JP 2010-59775 A

  Various types of shutter devices have different shutter curtain width dimensions, and some shutter curtain width dimensions, that is, the left and right dimensions of the shutter curtain are large. In a shutter device in which the left and right dimensions of the shutter curtain are large, the shutter curtain closes and moves while a large vertical deflection occurs on the seat plate forming the lower end of the shutter curtain. Arrives on the floor and is fully closed.

  In this way, when the shutter curtain is landed on the floor and is fully closed, when the part of the seat plate that was at the lowest position due to bending has landed on the floor, the shutter curtain becomes an obstacle. As in the case of contact with the tensioning force, a tensioning force acts on the tensioning force acting member, and thereafter, the other part of the seat plate is further lowered to fully close the shutter curtain, so that the tensioning force acting member is further pulled. As a result, a large amount of tension is generated in the tension acting member.

  For this reason, the device which can cope effectively with the big tensile amount which acts on the tension force action member is calculated | required.

  An object of the present invention is to provide an opening / closing body stopping device for an opening / closing device that can effectively cope with a large amount of tension acting on a tension acting member.

  An opening / closing body stop device for an opening / closing apparatus according to the present invention includes an opening / closing body that opens and closes in the vertical direction, brake means for stopping the closing movement of the opening / closing body, A tension force acting member that exerts a tension force when contacted, and a device that mechanically turns on and off the brake means, and turns on the brake means when the tension force acts on the tension force acting member. An automatic closing device for stopping the closing movement of the opening / closing body, and the tensioning force acting member is connected between the tensioning force acting member and the automatic closing device. An opening / closing member stop device for an opening / closing device, comprising: an intermediate member for operating the automatic closing device to turn on the brake means when the tension force acts on a force acting member; Connecting portions of the tension acting member coupled to the timber is characterized in that it is movably coupled to the intermediate member.

  In the device according to the present invention, the connecting portion of the tension acting member connected to the intermediate member is movably connected to the intermediate member, and when a large tensile amount is generated in the tension acting member, the tension acting is applied. The connection part of a member will move with respect to an intermediate member, Therefore For this reason, it becomes possible to cope effectively with a large amount of tension acting on the tension acting member.

  In the present invention, when the automatic closing device is operated by moving the intermediate member to turn on the brake means, the connecting portion of the tension force acting member is connected to the tension force acting member when a large tensile amount is generated. In order to move the intermediate member relative to the intermediate member, for example, the large tensile amount is set to a tensile amount larger than the reference tensile amount, and the reference tensile amount is set so that the connecting portion of the tension force acting member is A tension amount generated in the tension force acting member by the intermediate member performing the motion without moving or hardly moving, and the large tension amount is used by the intermediate member and the tension force acting member. The tensile amount generated by the movement of the connecting portion relative to the intermediate member can be obtained.

  In the present invention, when the automatic closing device has a slide member for turning the brake means on and off by reciprocating sliding, the connecting portion of the tension force acting member is connected to the tension force acting member. In order to move the large tension amount relative to the intermediate member when a large tension amount is generated, for example, the tension acting member is further moved to a position where the brake means that has been turned on cannot be returned to the off position. The amount of tension for moving the slide member can be used.

  Further, in the present invention, as described above, in order to connect the connecting portion of the tension acting member movably to the intermediate member with respect to the large tensile amount of the tension acting member, a guide portion is formed on the intermediate member. It is preferable that the connecting portion of the tension force acting member is guided by the guide portion and is movable with respect to the intermediate member.

  According to this, the movement of the connecting portion of the tension acting member with respect to the intermediate member can be smoothly performed by the guiding action of the guide portion.

  The guide portion may be of any structure and shape as long as it can guide the movement of the connecting portion of the tension acting member with respect to the intermediate member, one example being a long hole, and the other example being Such as grooves and ridges.

  The guide portion may have a first portion and a second portion, and may have a bent shape in which the first portion and the second portion are connected with a bending angle.

  Furthermore, when the guide portion has such a bent shape, the guide portion may have a V shape or a substantially V shape whose bending angle is greater than 90 degrees.

  Further, when the guide portion is bent, the second portion when the connecting portion of the tension force acting member moves relative to the intermediate member guided by the guide portion is used as the tension force acting member. It is assumed that it extends in the same or substantially the same direction as the acting tension force, and is guided by the second portion so that the connecting portion of the tension force acting member moves relative to the intermediate member. It is preferable.

  According to this, when a large tensile amount is generated in the tension force acting member, the second portion extends in the same or substantially the same direction as the tension force acting on the tension force acting member. The movement of the connecting portion of the tension acting member based on the amount can be smoothly performed by the second portion without generating a large frictional force or the like with the intermediate member.

  In the apparatus according to the present invention, an elastic member is disposed on the intermediate member, and the connecting portion of the tension acting member has a component in a direction opposite to the moving direction of the connecting portion. An elastic force may be applied, and the connecting portion of the tension force acting member may move relative to the intermediate member against the elastic force.

  According to this, before a large tensile amount occurs in the tension force acting member, the connecting portion of the tension force acting member can be stopped at the original position before the movement by the elastic force of the elastic member, When a large tensile amount is generated in the tension force acting member, the connecting portion of the tension force acting member can be moved relative to the intermediate member against the elastic force of the elastic member.

  Then, by moving the connecting portion of the tension acting member against the intermediate member against the elastic force of the elastic member, the connecting portion of the tension acting member is moved to the original position before the movement. Since the elastic restoring force for restoring is accumulated, when the above-described large pulling amount disappears, the elastic restoring force causes the connecting portion of the tension acting member to return to the original position before the movement. be able to.

  In order to return the connecting portion of the tension force acting member to the original position before the movement by the elastic restoring force accumulated in the elastic member when such a large tensile amount disappears, What is necessary is just to have the part which has maintained the contact state with this connection part in the whole range which the connection part of a force action member moves.

  Such an elastic member may be of any structure and shape, and may be, for example, a torsion coil spring or a coil spring.

  In addition, when the intermediate member is a rotatable member that is rotatable about an axis, and the rotating member is provided with a turning force in one direction by a spring, the elastic recovery described above is performed. The spring may be an elastic member that accumulates force.

  According to this, since the elastic member for accumulating the elastic restoring force and the spring for applying the rotational force in one direction to the intermediate member can be made the same member, the structure can be simplified by sharing the member. Can be planned.

  Further, in the device according to the present invention, the above-described brake means may be a single device alone, or the brake means may be provided on the opening / closing body at least of an opening movement and a closing movement. A part of the opening / closing machine provided with the electric motor means for performing the opening movement may be configured.

  Furthermore, the present invention can be applied to an arbitrary opening / closing device in which an arbitrary opening / closing body is freely movable, and an example of the opening / closing device is a shutter device in which the opening / closing body is a shutter curtain, In addition, the present invention can be applied to various opening / closing devices such as an awning device and a smoke-proof banner device.

  Further, when the present invention is applied to a shutter device, the shutter device may be a disaster prevention shutter device for forming a disaster prevention zone with a fully closed shutter curtain, or the shutter is operated by operating the operation device. A shutter device for management in which the curtain opens / closes and stops moving, or a shutter device for both management and disaster prevention may be used.

  According to the present invention, it is possible to effectively cope with a large tensile amount acting on the tension acting member.

  FIG. 1 shows the entire shutter device according to the present embodiment, and FIG. 1 shows a half in which the opening / closing movement direction is up and down, and the shutter curtain 1 that is closed and moved downward is closed to about half. It shows when it is in the closed state. The opening that is opened and closed by the shutter curtain 1 is an entrance 2 formed in the building. The entrance 2 includes a left and right building housing 3 such as a wall and a lower end of the shutter curtain 1 when fully closed. It is surrounded by a floor 4 and a ceiling member 5 that are counterpart members to be hit. A pair of left and right guide rails 6 slidably inserted at both ends in the left and right direction of the shutter curtain 1, in other words, both ends in the width direction of the shutter curtain 1, are attached to the left and right building housings 3. The shutter curtain 1 is moved up and down by being guided by these guide rails 6 as members.

  A shutter box 8 is disposed in a ceiling space 7 partitioned by the ceiling member 5 with respect to the entrance / exit 2, and this shutter box 8 is shown in FIG. 2, which is a cross-sectional view taken along line S <b> 2-S <b> 2 of FIG. As shown in the figure, it is coupled to a building housing 9 such as a falling wall existing in the ceiling space 7 with a coupler 10 such as a bolt. A take-up shaft 11 is horizontally accommodated in the shutter box 8, and the take-up shaft 11 is rotatably supported by the left and right side portions 8A and 8B shown in FIG. Yes. As shown in FIG. 1, an opening / closing machine 13 is connected to one end of the winding shaft 11 via a driving force transmission means 12 using a sprocket wheel and a roller chain. The opening / closing machine 13 serving as a driving device for driving the winding shaft 11 is also shown in FIG. 2, and the rotational force of the driving shaft 14 of the opening / closing machine 13 is driven by a driving sprocket attached to the driving shaft 14. A driving force transmission means 12 includes a wheel 12A, a driven sprocket wheel 12B attached to the one end of the winding shaft 11, and an endless roller chain 12C bridged between the sprocket wheels 12A and 12B. Then, it is transmitted to the winding shaft 11.

  As shown in FIG. 2, the opening / closing device 13 of the present embodiment is attached to a bracket member 15 coupled to one of the left and right side surface portions 8A and 8B of the shutter box 8. ing.

  As can be seen from FIG. 2, the shutter curtain 1 is wound around the winding shaft 11, and the upper end of the shutter curtain 1 is coupled to the outer peripheral surface of the winding shaft 11. Further, the lower part of the shutter curtain 1 from the winding shaft 11 is suspended below the ceiling member 5 through a slit 17 provided in the lintel 16 disposed on the ceiling member 5, and further the shutter. Both ends in the width direction of the curtain 1 are slidably inserted into the left and right guide rails 6 as described above. The lintel 16 is formed by lintel members 16A and 16B arranged to face each other, and a slit 17 is formed between the lintel members 16A and 16B.

  FIG. 3 is a cross-sectional view showing the internal structure of the switch 13. As shown in FIG. 3, the opening / closing machine 13 has a DC or AC electric motor means 18 and a brake means 19 arranged in parallel in the axial direction. The drive shaft 14 described above is an electric motor means. The rotary shaft is fixedly arranged at the center of the 18 rotating rotors 18A. A disc-shaped brake shoe 20 is coupled to the end of the drive shaft 14 on the brake means 19 side. The brake means 19 is provided with a brake shaft 21 that is slidable by a fixed distance in the axial direction. The brake shaft 21 is coupled to a brake drum 22 facing the brake shoe 20 in the axial direction. The brake shaft 21 and the brake drum 22 in the normal state are pressed toward the electric motor means 18 by the spring 23, and therefore the brake means 19 is turned on by the pressure contact between the brake shoe 20 and the brake drum 22. Accordingly, the drive shaft 14 of the electric motor means 18 at this time is not rotated by the braking force of the brake means 19.

  On the other hand, when the solenoid 24 arranged in the brake means 19 is energized, the brake shaft 21 and the brake drum 22 slide in a direction away from the electric motor means 18 against the spring 23 by the magnetic force of the solenoid 24. For this reason, the pressure contact between the brake shoe 20 and the brake drum 22 is released, and the brake means 19 is turned off. Therefore, at this time, the drive shaft 14 of the electric motor means 18 can be rotated by energizing the coil 25.

  Thus, when the solenoid 24 is energized, the brake means 19 is turned off, and when this energization is stopped, the brake means 19 is turned on, so that the brake means 19 is electrically turned on and off. ing.

  In the present embodiment, as shown in FIG. 1, a control device 26 is attached to the switch 13, and the control device 26 electrically connects the electric motor means 18 and the brake means 19 of the switch 13. To control. The control device 26 may be attached to a member, means, device, or the like different from the opening / closing device 13, and the arrangement location thereof is arbitrary.

  Among the left and right building housings 3 shown in FIG. 1, in one building housing 3A, the shutter curtain 1 is opened and moved upward with respect to the doorway 2, closed and moved downward, and the movement is stopped. An operating device 30 is attached to perform the above. The operation device 30 is provided with an “open” button, a “close” button, and a “stop” button. Further, the shutter curtain 1 occupies most of the area of the shutter curtain 1, and a curtain body 1A whose upper end is coupled to the winding shaft 11 and a seat plate 1B provided at the lower end of the curtain body 1A. It has become. The curtain body 1A of the present embodiment is formed by connecting a large number of slats vertically.

  The curtain main body 1A is an opening / closing body main body in the present embodiment, and the seat plate 1B is an end member in the present embodiment.

  When the shutter curtain 1 reaches the height position of the lintel 16 disposed on the ceiling member 5 as described above, or when the occupant plate 1B has the lintel 16 and the floor 4 as shown in FIG. When the shutter button 1 of the operating device 30 is operated when the shutter curtain 1 that has reached the halfway position is in the half-closed state (half-open state), the control device 26 receives a signal from the “close” button. As a result of this control, the solenoid 24 of the brake means 19 is energized, so that the brake means 19 is turned off. Thus, the shutter curtain 1 is rotated downward from the take-up shaft 11 by rotating the take-up shaft 11 and the drive shaft 14 by the dead weight of the shutter curtain 1, and the shutter curtain 1 that is closed and moved thereby is brought into the fully closed position. When it reaches, the control of the control device 26 to which a signal from a sensor (not shown) that detects the fully closed position is inputted, the energization to the solenoid 24 is cut off, and the brake means 19 is turned on by the spring 23. In addition, when the shutter curtain 1 is fully closed, or the shutter curtain 1 is in a half-open state where the seat plate 1B reaches the midway position between the lintel 16 and the floor 4 as shown in FIG. When the “open” button is operated in the semi-closed state), the solenoid 24 of the brake means 19 is energized under the control of the control device 26 to which a signal from the “open” button is input. While being turned off, the coil 25 of the electric motor means 18 is energized under the control of the control device 26. For this reason, the drive shaft 14 rotates in the reverse direction, and this rotation is transmitted to the winding shaft 11 via the driving force transmission means 12 described above, and the shutter curtain 1 is moved to the winding shaft 11 by the reverse rotation of the winding shaft 11. It is rolled up and moved. When the shutter curtain 1 reaches the fully open position, the energization to the solenoid 24 is cut off and the brake means 19 is turned on by the spring 23 under the control of the control device 26 that receives a signal from a sensor (not shown) that detects the fully open position. At the same time, the power to the coil 25 is cut off by the control of the control device 26.

  Further, when the “stop” button is operated while the shutter curtain 1 is being closed and moved, the energization of the solenoid 24 is cut off by the control of the control device 26 to which a signal from the “stop” button is input. When the brake means 19 is turned on by the spring 23, the shutter curtain 1 stops at that position. Further, when the “stop” button is operated while the shutter curtain 1 is being opened and moved, the energization to the solenoid 24 is cut off by the control of the control device 26 to which a signal from the “stop” button is input. The brake means 19 is turned on by the spring 23, and energization of the coil 25 of the electric motor means 18 is cut off by the control of the control device 26, whereby the shutter curtain 1 stops at that position.

  As can be seen from the above description, the floor 4 and the guide rail 6, the shutter box 8, the bracket member 15 coupled to the shutter box 8, the lintel 16 and the like with respect to the shutter curtain 1 that opens and closes. Therefore, the floor 4, the guide rail 6, the shutter box 8, the bracket member 15, the lintel 16, and the like are immovable members for the shutter curtain 1.

  The shutter curtain 1 is closed and moved not only by its own weight, but by its own weight and the positive rotation of the drive shaft 14 driven by the electric motor means 18. You may make it make it.

  Further, as described above, the take-up shaft 11 that can be rotated forward and backward is provided with a return spring by a torsion coil spring or a mainspring spring in which a return force is accumulated during the closing movement of the shutter curtain 1, and the shutter curtain. One upward opening movement may be performed using the return force accumulated in the return spring as an auxiliary force.

  In the present embodiment, as shown in FIG. 3, a lever member 31 is disposed at the end of the brake shaft 21 opposite to the electric motor means 18 side. The lever member 31 penetrates the brake shaft 21 and includes a first portion 31A and a second portion 31B that are divided with the brake shaft 21 as a boundary. A first bent portion 31C is formed in the first portion 31A, and a second bent portion 31D is formed in the second portion 31B. When a load is applied to the first portion 31A in the A direction, that is, the side opposite to the electric motor means 18, the first portion 31A swings in the A direction with the second bent portion 31D as a fulcrum, so that the brake shaft 21 and the brake drum 22 slide in the A ′ direction which is the same direction as the A direction. For this reason, the brake means 19 can be turned off without energizing the solenoid 24.

  For this reason, the brake means 19 is also a mechanical brake means that turns on and off by the action of the load in the A direction on the first portion 31A and the spring 23 when the load is released.

  In addition, it is performed by the below-mentioned automatic closing device 32 attached to the opening / closing machine 13 that the load to A direction acts on 31 A of 1st parts. As will be described later, the automatic closing device 32 is a mechanical control device for mechanically controlling the opening / closing machine 13 serving as a driving device for driving the shutter curtain 1.

  Further, when a load in the same direction as the A direction acts on the second portion 31B, the second portion 31B swings in the same direction as the A direction with the first bent portion 31C as a fulcrum. 21 and the brake drum 22 slide in the A ′ direction. Therefore, the brake means 19 can be turned off at this time without energizing the solenoid 24.

  Thus, applying a load in the same direction as the A direction to the second portion 31B can be performed manually. For this reason, the opening / closing machine 13 according to this embodiment can turn off the brake means 19 by manual operation. Note that the second portion 31B may be omitted leaving the second bent portion 31D.

  4 shows a mechanical obstacle for mechanically detecting the obstacle 34 when the seat plate 1B of the shutter curtain 1 abuts against the obstacle 34 shown in FIG. A detection device 35 is shown. The mechanical obstacle detection device 35 includes a locking wire 36 serving as a bridging member having a portion spanned between the lintel 16 serving as the stationary member and the shutter curtain 1. And one end of the lock wire 36 having flexibility is coupled, and the first processing device 37 for processing the one end is connected to the other end of the lock wire 36. The second processing unit 38 processing the other end and the locking wire 36 are disposed in the middle of the length of the locking wire 36, and the locking wire 36 is mechanically moved when the shutter curtain 1 comes into contact with the obstacle 34. And, in other words, a mechanical coupling device 39 for mechanically coupling the shutter curtain 1 and the locking wire 36 to each other. The mechanical coupling device 39 is attached to the shutter curtain 1 as will be described later.

  The locking wire 36 serving as the above-described bridging member is also a flexible string-like member and an elongated member in the present embodiment.

  The first processing device 37, the second processing device 38, and the mechanical coupling device 39 are connected to each other by the lock wire 36, and therefore, mechanical obstacles including these devices 37 to 39 as constituent elements. The detection device 35 is a unit that is easy to handle.

  The first processing device 37 is provided with a rotatable reel 40, and the locking wire 36 is wound around the reel 40 to which one end of the locking wire 36 is coupled. A return spring 41 such as a mainspring spring is connected to the reel 40, and when the lock wire 36 rotates the reel 40 and is drawn out from the reel 40, a return force is accumulated in the return spring 41. When the locking wire 36 is slack, the reel 40 is rotated in the direction in which the locking wire 36 is wound by the return force accumulated in the return spring 41. For this reason, in the present embodiment, the first processing device 37 is a winding device for winding the locking wire 36 so as to be unwound.

  The second processing device 38 is provided with a rotating member 42 and a link member 43, and the other end of the lock wire 36 is connected to the link member 43.

  FIG. 7 shows a front view when the mechanical coupling device 39 is attached to the shutter curtain 1. FIG. 8 is a cross-sectional view taken along line S8-S8 of FIG. 7. FIG. 8 shows the internal structure of the seat plate 1B of the shutter curtain 1 described above, and FIG. The mechanical coupling device 39 is indicated by a two-dot chain line. As described with reference to FIG. 1, the shutter curtain 1 occupies most of the area of the shutter curtain 1, and is as shown in FIG. And a seat plate 1B provided at the lower end of the curtain body 1A and serving as an end member in the present embodiment. The seat plate 1B is fixed to the lower portion of the curtain body 1A, and a movable portion 70B is disposed below the fixed portion 70A and is movable in the vertical direction with respect to the fixed portion 70A. It consists of.

  Further, as shown in FIG. 7, the shutter curtain 1 of the present embodiment includes a curtain main portion 71A and a curtain sub-portion 71B. The curtain main portion 71A includes a curtain main body 1A and a seat plate 1B. The curtain sub-part 71B is constituted by the movable part 70B of the seat plate 1B. Accordingly, the curtain sub-portion 71B is disposed at the end of the shutter curtain 1 on the closing side. The curtain main portion 71A is an open / close body main portion in the present embodiment, and the curtain sub-portion 71B is an open / close body sub-portion in the present embodiment.

  As shown in FIG. 8, the fixing portion 70 </ b> A of the seat plate 1 </ b> B is formed by inner and outer members 75 and 76 each having a box shape in cross section, and the outer member 75 is divided in the thickness direction of the shutter curtain 1. The two divided members 75A and 75B are arranged, and these divided members 75A and 75B are coupled to the lower end portion of the curtain body 1A by a coupling tool 77 such as a bolt or a nut. Further, the lower surfaces of the inner and outer members 75 and 76 have an opening 78, and the upper end of the rising portion 79 of the movable portion 70B of the seat plate 1B is inserted into the internal space of the fixed portion 70A from the opening 78. At the upper end of the rising portion 79, extending portions 79A and 79B extending outward in the thickness direction of the shutter curtain 1 are formed, and these extending portions 79A and 79B are formed at the lower end of the inner member 76 of the fixing portion 70A. By riding on the upper surfaces of the formed projecting piece portions 76A and 76B, the lower limit of movement of the movable portion 70B relative to the fixed portion 70A is defined.

  A swinging member 81 that can swing up and down around a fulcrum shaft 80 extending in the width direction of the shutter curtain 1 is housed inside the fixed portion 70A. As shown in FIG. 14, the swinging member 81 is moved when the movable part 70B is lifted with respect to the fixed part 70A, that is, when the shutter curtain 1 in the closing movement is in contact with the obstacle 34 shown in FIG. When in contact, the extending portion 79A of the rising portion 79 of the movable portion 70B pushes up the protruding piece 81A of the swinging member 81, so that the swinging member 81 swings upward about the fulcrum shaft 80. Further, the fixed portion 70A and the movable portion 70B constituting the seat plate 1B have a length that extends to the left and right guide rails 6 shown in FIG. It has an extended length.

  The swing member 81 and the movable portion 70B are formed of an extrusion molded product or a pultruded molded product made of, for example, an aluminum alloy. When the lateral width of the entrance / exit 2 shown in FIG. 1 is large, it is difficult to form the swinging member 81 and the movable portion 70B with a single continuous extruded product or pultruded product. The swing member 81 and the movable portion 70B are formed by a plurality of extrusion molded products or pultruded molded products arranged in the length direction (width direction of the shutter curtain 1).

  FIG. 11 shows a case where the swing member 81 is formed by a plurality of molded products 82 arranged in the length direction. The swing member 81 is formed by connecting two molded products 82 adjacent to each other by connecting members 83 provided with portions 83A and 83B press-fitted into the molded products 82 at both ends. . The molded product 82 and the connecting member 83 may be joined by press-fitting as described above, using a fastener such as a screw, welding, or bonding. FIG. 12 shows a case where the movable portion 70B is formed by a plurality of molded products 84 arranged in the length direction. The movable portion 70B is formed by simply arranging a plurality of molded products 84 in the above-described length direction. Therefore, unlike the case of the swing member 81, the molded products 84 are not connected.

  Thus, even if the movable part 70B is formed by not connecting the molded products 84 to each other, thereby simplifying the structure of the movable part 70B and facilitating its manufacture, the swing member 81 extends to the left and right guide rails 6. Since it is in a continuous state, the movable portion 70B during the closing movement of the shutter curtain 1 no matter where the obstacle 34 shown in FIG. 1 exists between the left and right guide rails 6. Among the plurality of molded products 84 forming the one, the one that the obstacle 34 hits or the two molded products 84 that are adjacent to each other are raised with respect to the fixing portion 70A, whereby the swinging member 81 is moved. It can be swung upward.

  As shown in FIG. 7, the mechanical coupling device 39 described in FIG. 4 is incorporated in the fixing portion 70 </ b> A of the seat plate 1 </ b> B. That is, the mechanical coupling device 39 is disposed on the fixed portion 70A among the curtain main body 1A constituting the curtain main portion 71A described above of the shutter curtain 1 and the fixed portion 70A of the seat plate 1B. FIG. 13 is a cross-sectional view taken along line S13-S13 of FIG. 7, and is a cross-sectional view of the seat plate 1B at a portion where the mechanical coupling device 39 is disposed. As shown in FIG. 13, the upper and front parts of the inner and outer members 75 and 76 forming the fixing part 70 </ b> A of the seat plate 1 </ b> B have positions corresponding to the arrangement position of the mechanical coupling device 39. , An opening 90 is formed by notching, and a mechanical coupling device 39 is inserted into the opening 90 from above and coupled to the fixing portion 70A. Therefore, the opening 90 is a mechanical coupling device arrangement portion for arranging the mechanical coupling device 39.

  As shown in FIGS. 13 and 14, the protruding piece 81A of the swinging member 81 that is swingable in the vertical direction around the fulcrum shaft 80 is provided on the lower second side shown in FIG. A pressing member 91 is attached at a position corresponding to the downward convex portion 62B of the lever member 62. For this reason, during the closing movement of the shutter curtain 1, the movable portion 70B of the seat plate 1B comes into contact with the obstacle 34 that exists in the lower side in the closing movement direction, and as described with reference to FIG. When the extending portion 79A of the movable portion 70B swings the swinging member 81 upward about the fulcrum shaft 80, as shown in FIG. 15, the pressing member 91 presses the convex portion 62B. The second lever member 62 swings upward about the fulcrum shaft 63. Accordingly, the friction member 68 attached to the second lever member 62 pushes up the portion 36A between the roller 58 and the roller 59 of the locking wire 36 upward.

  By this push-up, the upper first lever member 61 swings upward about the fulcrum shaft 63 via the friction member 67 attached to the first lever member 61, and this upward swing As a result, the torsion coil spring 64 is compressed, so that the portion 36A between the roller 58 and the roller 59 of the lock wire 36 is clamped with a large load from above and below by the friction members 67 and 68 of the two lever members 61 and 62. By this clamping, the portion 36A of the lock wire 36 is locked, and the shutter curtain 1 and the lock wire 36 are mechanically coupled by the mechanical coupling device 39 by this locking. Become.

  As shown in FIG. 13, when the movable part 70B of the seat plate 1B reaches the lowest position with respect to the fixed part 70A, the protruding piece 81A of the swinging member 81 extends from the movable part 70B. By hitting the portion 79A, the downward swing of the swing member 81 about the fulcrum shaft 80 is restricted.

  As described above, when the shutter curtain 1 that is being closed is in contact with the obstacle 34, the friction member 67, 68 of the two lever members 61, 62 causes a large load on the portion 36A of the lock wire 36. In order to be locked, before the shutter curtain 1 comes into contact with the obstacle 34, in other words, when the movable part 70B of the seat plate 1B reaches the lowest position with respect to the fixed part 70A, It is important that the mechanical coupling device 39 is disposed at an appropriate vertical position with respect to the pressing member 91 of the swing member 81. Arranging the mechanical coupling device 39 at an appropriate vertical position with respect to the pressing member 91 of the swinging member 81 means that the mechanical coupling device 39 is attached to the fixing portion 70A of the seat plate 1B. That is, the coupling device 39 is attached to an appropriate vertical position in the fixing portion 70A. The present embodiment is devised so that the mechanical coupling device 39 can be attached to an appropriate vertical position in the fixing portion 70A.

  Next, this device will be described. As shown in FIG. 4, protrusions 55D are formed on both side surfaces of the case 55 of the mechanical coupling device 39, and the mechanical coupling device 39 is seated using these protrusions 55D. It is attached to the fixing portion 70A of the plate 1B. Since the attachment structure using these protrusion pieces 55D is the same, the attachment structure for one protrusion piece 55D will be described with reference to FIG.

  A base member 92 is coupled to the inner upper surface of the fixing portion 70A by a fastening tool 93 such as a rivet. The base member 92 is formed on the above-described inner and outer members 75 and 76 forming the fixing portion 70A. A screw shaft member 95 that penetrates the holes 94A and 94B and protrudes upward from the fixing portion 70A is provided. After inserting one or a plurality of washers 96 into the screw shaft member 95, the screw shaft member 95 is inserted into the hole 55E of the projecting piece 55D. By changing the number of washers 96 inserted into the screw shaft member 95 or not inserting the washers 96 into the screw shaft member 95, the vertical arrangement position of the mechanical coupling device 39 in the fixing portion 70A is adjusted. Become. Thereby, the arrangement position of the mechanical coupling device 39 can be set to an appropriate vertical position with respect to the pressing member 91 of the swing member 81.

  In order to be able to confirm whether or not the mechanical coupling device 39 is arranged at an appropriate vertical position with respect to the pressing member 91 of the swinging member 81 as shown in FIG. In addition, a window hole 55F is formed in the front portion 55C of the case 55 of the mechanical coupling device 39. From the window hole 55F, when the movable portion 70B of the seat plate 1B reaches the lowest position with respect to the fixed portion 70A, the friction member 68 of the lower second lever member 62 described above and the lock wire 36 The distance in the vertical direction between the portion 36A described above can be checked, and when the vertical distance becomes a value within a predetermined appropriate range, the nut 97 shown in FIG. The screw shaft member 95 is screwed and tightened. Thereby, the mechanical coupling device 39 is fixed to the fixing portion 70A of the seat plate 1B. Then, the window hole 55F is shielded with a shielding member such as a tape to prevent dust and the like from entering the inside of the case 55.

  As described above, the mechanical coupling device 39 is attached to an appropriate vertical position in the fixed portion 70A. As a result, when the shutter curtain 1 that is being moved is in contact with the obstacle 34, the mechanical coupling device 39 is mechanically coupled. The friction members 67 and 68 of the two lever members 61 and 62 provided in the device 39 can lock the portion 36A of the locking wire 36 with a large load.

  As described above, the structure for setting the arrangement position of the mechanical coupling device 39 to an appropriate vertical position with respect to the pressing member 91 of the swinging member 81 is not limited to the above-described structure.

  FIG. 10 shows a structure according to another method. In the structure of FIG. 10, a nut 98 is used instead of the washer 96 of FIG. When the nut 98 is rotated, the nut 98 moves up and down little by little along the screw shaft member 95. The height position of the mechanical coupling device 39 in the fixed portion 70A can be finely adjusted.

  The number of nuts 98 may be one. However, in FIG. 10, two nuts 98A and 98B are used, and these nuts 98A and 98B can press one nut against the other nut so that the height of the nuts 98A and 98B in the screw shaft member 95 can be increased. It is a double nut that can fix the position. For this reason, the arrangement position of the mechanical coupling device 39 can be more reliably fixed.

  As described above, the work for attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B is performed by replacing the shutter curtain 1 of the shutter device of the present embodiment with the shutter device according to the present embodiment. This is performed after the guide rail 6 attached to the left and right building frames 3 shown in FIG. That is, the installation work of the shutter device itself excluding the mechanical obstacle detection device 35 described above with reference to FIG. 4 is performed first, and then the installation work of the mechanical obstacle detection device 35 is performed. The installation work of the mechanical obstacle detection device 35 includes the work of attaching the unit structure 45 to the lintel 16 and the work of attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B. Of the work of attaching the unit structure 45 to the lintel 16 and the work of attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B, either work may be performed first, and these work are performed simultaneously ( Including the case of being said to be substantially simultaneous).

  Then, when performing the installation work of the mechanical obstacle detection device 35 in this way, the opening 90 shown in FIG. 14 for arranging and attaching the mechanical coupling device 39 to the fixing portion 70A of the seat plate 1B. Etc. are preferably formed in advance in a factory.

  In the present embodiment, as described above, the mechanical obstacle detection device 35 including the locking wire 36, the first processing device 37, the second processing device 38, and the mechanical coupling device 39 is unitized. Therefore, the installation work for the mechanical obstacle detection device 35 transported from the factory to the building where the shutter device according to the present embodiment is installed can be easily performed, and the first processing device 37 and Since the second processing device 38 is a unit structure 45 and only the first processing device 37 and the second processing device 38 are unitized, the first processing device 37 and the second processing device 38 are sprinkled. The attachment work to the length 16 can be easily performed.

  As described above, when the mechanical coupling device 39 is attached to the fixed portion 70A of the seat plate 1B, the first processing device 37 and the second processing device 38 of FIG. The locking wire 36 whose both ends are coupled to each other is bridged between the lintel 16 and the shutter curtain 1. Further, since the lock wire 36 is folded back by the mechanical coupling device 39, as shown in FIG. 1, the first portion 36B extending from the lintel 16 to the shutter curtain 1, and the shutter curtain 1 The second portion 36 </ b> C extends from the lintel 16 to the lintel 16. Of the locking wire 36, the portion 36 </ b> A shown in FIGS. 6 and 15 corresponding to the mechanical coupling device 39 becomes a folded portion of the U-shaped locking wire 36.

  When the shutter curtain 1 is closed and moved, the locking wire 36 rotates the reel 40 of the first processing device 37 according to the weight of the shutter curtain 1 and is fed out from the reel 40, whereby the first wire Each length of the part 36B and the 2nd part 36C becomes long. Further, when the shutter curtain 1 is opened and moved upward by the rotation of the drive shaft 14 of the opening / closing device 13 described above, the locking wire 36 is slackened. Therefore, the return force of the return spring 41 described above is opposite to the above. The locking wire 36 is taken up by the reel 40 that rotates in the direction, whereby the length of each of the first portion 36B and the second portion 36C is shortened. For this reason, the locking wire 36 follows the opening / closing movement of the shutter curtain 1.

  In this embodiment, as can be seen from FIG. 1, the unit structure 45 including the mechanical coupling device 39 and the first processing device 37 and the second processing device 38 is disposed at the central position B in the width direction of the shutter curtain 1. The mechanical coupling device 39 and the unit structure 45 constituting the above-described mechanical obstacle detection device 35 are not moved from the central position B to one side in the width direction of the shutter curtain 1. It is placed at a displaced position. This displaced position is a position on the side where the above-described opening / closing device 13 serving as a driving device for driving the shutter curtain 1 and the above-described automatic closing device 32 attached to the opening / closing device 13 are arranged. .

  Further, as shown in FIG. 1, the extending direction of the first portion 36B and the second portion 36C of the locking wire 36 is a vertical direction (substantially a vertical direction) along the curtain body 1A of the shutter curtain 1. The first portion 36B and the second portion 36C are parallel to each other (including what can be said to be substantially parallel to each other).

  As shown in FIGS. 2 and 4, the first portion 36 </ b> B and the second portion 36 </ b> C of the lock wire 36 are disposed at the inner position of the slit 17 for hanging the shutter curtain in the lintel 16. For this reason, the first portion 36 </ b> B and the second portion 36 </ b> C do not interfere with the lintel 16. In other words, in the first processing device 37 and the second processing device 38 arranged on the upper surface of the lintel 16, the position of the portion where the first portion 36 </ b> B and the second portion 36 </ b> C of the locking wire 36 hang down is the lintel 16. Is disposed on the lintel 16 so as to be positioned above the internal position of the slit 17 for hanging the shutter curtain.

  Further, as shown in FIG. 13, the arrangement position of the mechanical coupling device 39 in the fixing portion 70A of the seat plate 1B is not the central position in the thickness direction of the shutter curtain 1, but the thickness of the shutter curtain 1 from this central position. The position is displaced to one side in the vertical direction. For this reason, the lock wire 36 is paraphrased to a position in the shutter curtain 1 that does not interfere with the curtain body 1A, as shown in FIG. 8, for both the first portion 36B and the second portion 36C. The shutter body 1 is disposed at a position away from the curtain body 1 </ b> A in the thickness direction of the shutter curtain 1. That is, since the curtain main portion 71A described above is configured by the curtain body 1A and the fixed portion 70A of the seat plate 1B, both the first portion 36B and the second portion 36C of the locking wire 36 are It is arranged at a position away from the curtain main part 71A (curtain body 1A) excluding the fixing part 70A where the mechanical coupling device 39 is arranged in the thickness direction of the shutter curtain 1.

  A portion of the curtain main portion 71A excluding the fixing portion 70A where the mechanical coupling device 39 is disposed is a curtain main body 1A, and the curtain main body 1A is a large portion that occupies most of the area of the shutter curtain 1. For this reason, as described above, both the first portion 36B and the second portion 36C of the locking wire 36 are separated from the curtain main portion 71A excluding the fixing portion 70A where the mechanical coupling device 39 is disposed. Since it is arranged at a position away from the thickness direction and does not interfere with the curtain main part 71A, it is a bridge member that is bridged between the lintel 16 and the shutter curtain 1, and this embodiment The locking wire 36 that is a mechanical member in the embodiment does not hinder the opening / closing movement of the shutter curtain 1.

  Further, as described above, the movable portion 70B of the seat plate 1B forms the curtain sub-portion 71B. As shown in FIG. 8, the thickness direction dimension of the shutter curtain 1 with respect to the movable portion 70B. Is W1. The dimension in the thickness direction of the shutter curtain 1 for the fixing portion 70A of the seat plate 1B that constitutes a part of the curtain main portion 71A described above is W2, and this W2 is smaller than W1. The lock wire 36 is disposed within the range of W1 and within the range of W2. Since the movable portion 70B forms the curtain sub portion 71B, the lock wire 36 is disposed within the shutter curtain thickness direction dimension W1 of the curtain sub portion 71B, and W1. Is a dimension that defines the overall thickness dimension of the shutter curtain 1, so that the locking wire 36 is disposed within the entire thickness dimension of the shutter curtain 1.

  Therefore, the lock wire 36 is disposed along the curtain body 1A of the shutter curtain 1, and thereby the first portion 36B and the second portion 36C of the lock wire 36 are disposed at positions that do not interfere with the curtain body 1A. Moreover, it can suppress that the whole thickness dimension of the shutter curtain 1 containing this wire 36 for a lock | rock becomes large.

  Even when W1 is equal to W2 (including a case where there is some difference and it can be said that it is substantially equal), the entire thickness of the shutter curtain 1 including the lock wire 36 is also included. An increase in the size can be suppressed.

  In the present embodiment, as described with reference to FIG. 4, the arrangement positions of the first processing device 37 and the second processing device 38 in the lintel 16 are adjusted in the thickness direction of the shutter curtain 1 by the long holes 47 and 50. Therefore, both the first portion 36B and the second portion 36C of the locking wire 36 are removed from the curtain main portion 71A excluding the fixing portion 70A where the mechanical coupling device 39 is disposed. It can arrange | position more reliably in the position away in the vertical direction. Also. By adjusting the arrangement positions of the first processing device 37 and the second processing device 38 in the lintel 16 separately for the first processing device 37 and the second processing device 38, the first portion 36B and the second portion 36C. Can also be performed for separating the curtain main portion 71A excluding the fixing portion 70A where the mechanical coupling device 39 is disposed in the thickness direction of the shutter curtain 1 by the same distance.

  FIG. 16 shows the internal structure of the second processing device 38. As described above, the second processing device 38 is provided with the rotating member 42 and the link member 43 to which the end of the locking wire 36 is connected, and is arranged facing each other in the thickness direction. The rotating member 42 and the link member 43 are rotatable in the vertical direction about the same shaft 42A. For this reason, the rotating member 42 and the link member 43 are coaxially rotating members. ing. The link member 43 is provided with means for biasing the link member 43 in the direction C about the shaft 42A, that is, the link member 43 is biased in the direction in which the second portion 36C of the lock wire 36 is pulled up. A spring 101 serving as an urging means is provided. The spring 101 is a torsion coil spring in which a coil portion is wound around a shaft 42 </ b> A, and one extending portion 101 </ b> A is locked to a machine frame 49 of the second processing device 38. The rotation of 43 in the C direction is regulated by the upper surface of the link member 43 coming into contact with the opening 49 </ b> B of the machine frame 49. In addition, a coil spring 100 is bridged between the rotating member 42 and the machine casing 49, and the rotating member 42 serves as a rotation urging means. Is urged to rotate.

  The connecting portion 43A of the locking wire 36 in the link member 43 is constituted by a pin 105 as a constituent member, and this pin 105 is slidably inserted into a long hole 106 formed in the link member 43. The long hole 106 has a V shape or a substantially V shape in which the first portion 106A and the second portion 106B are connected with a bending angle, and the bending angle is larger than 90 degrees. Further, the other extending portion 101B of the torsion coil spring 101 is locked to the pin 105, and thereby, a biasing force in the C direction about the shaft 42A is applied to the link member 43. Further, a roller 107 is rotatably attached to one end portion of the pin 105 protruding from the long hole 106, and a contact surface 42B on which the roller 107 contacts from above is formed on the rotating member 42. Has been. FIG. 17 is a view of the rotating member 42 and the link member 43 as seen from above in order to show the relationship between the rollers 107 and the contacted surface 42B.

  As shown in FIG. 16, an electric switch 108 is disposed in the machine casing 49 of the second processing device 38 in the vicinity of the link member 43 on the upper side of the link member 43. The actuator 109 is in contact with the upper surface of the link member 43. The electric switch 108 is connected to the control device 26 shown in FIG.

  In addition, as shown in FIG. 16, gear teeth 42C are formed on a part of the outer peripheral portion of the rotating member 42. For this reason, the rotating member 42 is formed with gear teeth 42C on a part thereof. It is a sector gear. A rotary damper 102 is attached to the machine frame 49, and the damper 102 includes a pinion gear 103 that meshes with the gear teeth 42 </ b> C of the rotating member 42. A plurality of blades arranged inside the damper 102 are attached to the rotation center shaft 104 of the pinion gear 103 via a one-way clutch, and the pinion gear 103 and the center shaft are rotated by the rotation member 42 rotating in the C direction. When 104 rotates in the E direction, each blade rotates in the viscous fluid filled in the damper 102 via the connected one-way clutch. For this reason, the rotation member 42 rotates in the C direction at a low speed by the resistance force of the viscous fluid. On the other hand, when the rotating member 42 rotates in the D direction opposite to the C direction and the pinion gear 103 and the central shaft 104 rotate in the F direction, the rotation in this direction is caused by the cutting action of the one-way clutch. Is not transmitted to the blade. For this reason, the rotation member 42 can rotate at high speed in the D direction.

  The number of dampers 102 may be two or more. When a plurality of dampers 102 are provided in this manner, the above-described resistance force for rotating the rotating member 42 in the C direction at a low speed can be increased, and thus the speed of the rotating member 42 in the C direction is desired. It can be slow enough to speed.

  In the second processing apparatus 38 configured as described above, when a downward tensile force acts on the second portion 36C of the locking wire 36 shown in FIG. 16, the link member 43 is centered on the shaft 42A. The torsion coil spring 101 is rotated in the D direction against the torsion coil spring 101. By this rotation, the rotating member 42 is pressed by the pressing force from the roller 107 that is in contact with the contacted surface 42B of the rotating member 42. It rotates in the D direction against the coil spring 100 around the shaft 42A. As a result, the pinion gear 103 and the central shaft 104 of the damper 102 rotate in the F direction, and the rotation in the F direction is not transmitted to the respective blades of the damper 102 due to the cutting action of the one-way clutch as described above. The moving member 42 and the link member 43 rotate at high speed in the D direction.

  When the downward tensile force acting on the second portion 36 </ b> C of the locking wire 36 is reduced or disappears, the link member 43 is centered on the shaft 42 </ b> A by the urging force accumulated in the torsion coil spring 101. The rotating member 42 also returns and rotates in the C direction about the shaft 42A by the biasing force accumulated in the coil spring 100. At this time, the pinion gear 103 and the central shaft 104 of the damper 102 rotate in the E direction, and the rotation in the E direction is transmitted to each blade of the damper 102 by the connection action of the one-way clutch. The return rotation of the moving member 42 in the C direction is performed at a low speed.

  However, the link member 43 at this time accumulates the pressure of the torsion coil spring 101 by separating the roller 107 upward from the contact surface 42B of the rotating member 42, in other words, by separating from the rotating member 42. Since the urging force causes the shaft 42A to return and rotate in the C direction, the link member 43 is returned to the C direction quickly. Therefore, even if the return of the rotating member 42 to the old position is delayed due to the delay action by the damper 102, the link member 43 returns to the old position at an early stage.

  As can be seen from the above description, the damper 102 provided in the second processing device 38 constitutes a delay device 99 for delaying the return of the rotating member 42 to the old position, and The rotating member 42 is an operation member of the delay device 99 and is a first operation member in the present embodiment.

  Further, the link member 43 is a second operating member in the present embodiment. That is, when a downward tensile force is applied to the second portion 36C of the locking wire 36 that is a string-like member and also serves as a tension acting member, the rotating member 42 that is the first actuating member is The link member 43 is connected to the link member 43 via the roller 107 and the abutted surface 42B. The link member 43 rotates the rotation member 42 in the D direction. In this case, the link member 43 is separated from the rotating member 42, and this separation causes the link member 43 to return to the old position earlier in the C direction than the rotating member 42 by the urging force accumulated by the torsion coil spring 101. The link member 43 is a second operating member in the present embodiment.

  The rotating member 42 and the link member 43, which are coaxial rotating members that rotate about the same shaft 42A, are moved in the C direction by the coil spring 100 and the torsion coil spring 101, both of which are elastic members. Therefore, the coil spring 100 and the torsion coil spring 101 serve as biasing means for biasing and returning the pivot member 42 and the link member 43 to the old positions. .

  Further, the roller 107 is provided on the link member 43, and the roller 107 contacts the contacted surface 42 </ b> B of the rotating member 42 to rotate the rotating member 42. The abutted surface 42 </ b> B is a contacted portion provided in the rotating member 42 while being a provided contact portion. Further, since the abutting portion of the present embodiment is a rotatable roller 107, the rotating member 42 is connected to the link member 43 via the roller 107 and the abutted surface 42B. When the moving member 42 rotates in the D direction, the roller 107 is in contact with the contacted surface 42B while rotating with respect to the rotating member 42. For this reason, the roller 107 rotates from the link member 43 to the rotating member 42. Power can be transmitted smoothly with reduced frictional force.

  Further, these control wires 111 to 113 are slidably inserted into the flexible outer cables 114 to 116. For this reason, the control wires 111 to 113 are protected by the outer cables 114 to 116.

  As shown in FIG. 16, the first control wire 111 extends to the second processing device 38, and the end of the first control wire 111 is connected to the rotating member 42 of the second processing device 38. It is connected. Therefore, the first control wire 111 is stretched between the automatic closing device 32 and the second processing device 38. As shown in FIG. 2, the first processing wire 111 and the outer cable 114 into which the first control wire 111 is inserted are part of the second processing device 38. The above-described unit structure 45 and the switch 13 are wired in the ceiling space 7 where they are arranged, and avoid the object 117 existing in the ceiling space 7, in other words, bypass the object 117. The first control wire 111 and the outer cable 114 are wired in a space where wiring is possible. Note that this space may exist in advance, and when the first control wire 111 and the outer cable 114 are wired, a part of the object 117 is cut out or a hole is provided in the object 117. Or formed.

  Thus, it is possible to wire the first control wire 111 and the outer cable 114 without interfering with the object 117 because the first control wire 111 and the outer cable 114 have flexibility. is there. The object 117 may be related to the building itself in which the shutter device of the present embodiment is installed, or may be related to a part of the shutter device of the present embodiment, for example, the shutter box 8 described above.

  Further, as shown in FIG. 16, the first control wire 111 and the outer cable 114 are inclined with respect to the second processing device 38 in the vicinity of the second processing device 38. Accordingly, the first control wire 111 and the outer cable 114 do not interfere with the coupling member 27 that couples the lintel 16A of the lintel 16 illustrated in FIG. Yes.

  As shown in FIGS. 20 and 21, the machine casing 110 of the automatic closing device 32 is provided with two rising portions 110 </ b> B and 110 </ b> C facing each other, and formed on these rising portions 110 </ b> B and 110 </ b> C. A plate-like slide member 120 having a length straddling the two rising portions 110B and 110C is slidably inserted into the holes 110D and 110E. A spring 121 is wound around the outer periphery of the slide member 120. Due to the spring force of the spring 121, a forward force toward the rising portion 110B is constantly acting on the slide member 120. The direction of the forward force is a direction in which the first portion 31A of the lever member 31 provided in the opening / closing machine 13 described in FIG.

  As shown in FIGS. 3 and 20, the actuating member 122 is attached to the bent portion 120 </ b> A that is bent downward at the front end of the slide member 120, and the first portion of the lever member 31. An actuated member 123 is erected and coupled to 31A. When the slide member 120 moves forward by the spring force of the spring 121, the load in the direction A shown in FIG. 3 is applied to the first portion 31A of the lever member 31 by the operating member 122 coming into contact with the operated member 123. It comes to work. As shown in FIG. 20, in this embodiment, the actuating member 122 is the head 124 </ b> A of the bolt 124. By moving forward and backward with respect to 120A, the distance between the actuating member 122 and the actuated member 123 can be adjusted to an appropriate dimension. After this adjustment, the lock nut 125 screwed into the bolt 124 is rotated, and the lock nut 125 is pressed against the bent portion 120A, whereby the position of the operating member 122 relative to the operated member 123 is adjusted. It can be fixed in an appropriate position.

  As shown in FIG. 21, a solenoid 126 is attached to the machine casing 110 of the automatic closing device 32, and a spring force of a spring 128 is applied to the plunger 127 of the solenoid 126 from the solenoid 126. It always works in the protruding direction. One end of an L-shaped bent lever member 129 that is rotatable about a central axis 129A is connected to the tip of the plunger 127 by a slide-type connecting portion 129B. A roller 130 is rotatably provided at the other end of the bent lever member 129.

  A concave portion 120 </ b> B is formed in the portion of the slide member 120 that faces the roller 130. A portion of the recess 120B on the backward side of the slide member 120 is an inclined surface 120C. In the automatic closing device 32, the spring 131 for applying a turning force in the G direction about the central axis 129A to the bending lever member 129 and the direction in which the plunger 127 protrudes from the solenoid 126 together with the spring 128 described above. And a spring 132 for urging the bending lever member 129 in the G direction about the central axis 129A. Due to the spring force of these springs 128, 131, 132, the normal roller 130 is fitted in the recess 120 </ b> B as shown in FIG. 21, and this fitting causes the above-described sliding by the spring 121. Advancement of member 120 is stopped. Thus, the position of the front end of the slide member 120 when the forward movement is stopped by the roller 130 fitted into the recess 120B is the H position among the three positions H, I, and J shown in FIG.

  The slide member 120 is a member for mechanically turning on and off the brake means 19 of the opening / closing machine 13 as will be apparent from the following description.

  As shown in FIG. 21, the automatic closing device 32 is provided with a micro switch 135 that is an electric switch, and this micro switch 135 is an actuator that is biased in a direction protruding from the micro switch 135 by a spring. 136 is provided. In addition, a dog member 137 is attached to the slide member 120 at a portion opposite to the concave portion 120 </ b> B, and the actuator 136 is in contact with the dog member 137.

  A connecting member 138 provided with a first connecting portion 138A and a second connecting portion 138B is connected to the slide member 120, and a connecting member 140 is connected to the tip of the plunger 127 of the solenoid 126, as described above. One end of the spring 132 is connected to the connecting member 140. The other end of the first control wire 111, which has one end connected to the rotating member 42 of the second processing apparatus 38 shown in FIG. 4, is the first of the connecting member 138 of the slide member 120. The end portion of the second control wire 112 is connected to the connecting portion 138A, the end portion of the third control wire 113 is connected to the connecting member 140 connected to the plunger 127, and the end portion of the connecting member 138 of the slide member 120 is connected. It is connected to the second connecting part 138B.

  As shown in FIG. 20, the first control wire 111 is provided with a bending portion 111 </ b> A inside the automatic closing device 32.

  Further, the second control wire 112 inserted into the outer cable 115 extends to the operating device 30 shown in FIG. 1, and the end of the second control wire 112 is connected to the operating device 30. It is connected to a manually operated member such as a lever member. Further, the third control wire 113 inserted into the outer cable 116 also extends to the operating device 30, and the end of the third control wire 113 is a lever member or the like disposed in the operating device 30. It is connected to a manual operation member.

  When the shutter device according to the present embodiment is used as a management shutter device, as described above, the shutter curtain 1 is operated by operating the “open”, “closed”, and “stop” buttons provided on the operation device 30. Are opened, closed, and stopped by electrical control of the switch 13 by the control device 26.

  When the shutter curtain 1 is closed and moved by the operation of the “close” button, in other words, the shutter device according to the present embodiment is managed so that the opening / closing movement and stoppage of the shutter curtain 1 are performed by the operation device 30. 3 when the brake means 19 of the switch 13 shown in FIG. 3 is electrically turned off by energization of the solenoid 24 and the shutter curtain 1 is closed and moved. 1 is present in the middle of the closing movement of the shutter curtain 1, FIG. 8, FIG. 13 and FIG. In other words, the movable portion 70B that forms the lower portion of the seat plate 1B of the shutter curtain 1 It abuts harm objects 34, lowering of the movable part 70B is stopped.

  Even if the lowering of the movable part 70B is stopped, the curtain main part 71A composed of the curtain main body 1A and the fixed part 70A of the seat plate 1B is lowered. Due to the relative rise of the curtain sub-portion 71B with respect to the portion 71A, the first lever member 61 and the second lever member 62 of the mechanical coupling device 39 described above are in friction members 67 and 68 as described with reference to FIG. The above-described folded portion 36A of the locking wire 36 is clamped, and the locking wire 36 is locked by this clamping. As a result, the shutter curtain 1 and the locking wire 36 serving as the bridging member according to the present embodiment are mechanically coupled by the mechanical coupling device 39.

  The lock wire 36 until then follows the closing movement of the shutter curtain 1 and is fed out from the reel 40 of the first processing device 37. Therefore, the movement of the shutter curtain 1 with respect to the shutter curtain 1 by the closing movement of the shutter curtain 1 Is generated in the locking wire 36. When the folding portion 36A of the locking wire 36 is sandwiched between the friction members 67 and 68 and the locking wire 36 is locked, the folding wire 36 is folded based on the dent deformation of the obstacle 34. The first portion 36B and the second portion 36C of the lock wire 36 that are folded back at the portion 36A include the weight of the portion of the shutter curtain 1 above the curtain sub-portion 71B, that is, the curtain main portion 71A. Therefore, the lock wire 36, particularly the second portion 36C, has a large weight. Tension is applied.

  Therefore, when the obstacle 34 comes into contact with the shutter curtain 1, the locking wire 36 becomes a tension force acting member to which a downward tension force due to the weight of the curtain main portion 71A acts, and this tension force acting member causes the shutter curtain 1 1 and the second processing device 38 having the delay device 99 including the rotary damper 102 of FIG.

  And in this embodiment, as FIG. 15 shows, the folding | returning part 36A of the wire 36 for a lock | rock is the friction member 67 with large frictional force provided in the 1st lever member 61 and the 2nd lever member 62, The friction members 67 and 68 prevent the locking wire 36 from sliding with respect to the first lever member 61 and the second lever member 62 because they are sandwiched and locked at 68. Further, in the present embodiment, the above-described shaft 63 serving as the pivot center axis of the first lever member 61 and the second lever member 62 is shared by the first lever member 61 and the second lever member 62. Therefore, the structure of the mechanical coupling device 39 can be simplified by reducing the number of members, and the positional relationship between the friction members 67 and 68 can be appropriately set. Can be clamped and locked more reliably by the friction members 67 and 68.

  Further, the contact of the shutter curtain 1 with the obstacle 34 is not performed below the position where the mechanical coupling device 39 is disposed, and the shutter curtain 1 is viewed from below the position where the mechanical coupling device 39 is disposed. Therefore, when the portion of the shutter curtain 1 where the mechanical coupling device 39 is arranged is about to move slightly in the closing direction of the shutter curtain 1, the first processing device 37 is used. The locking wire 36 fed out from the reel 40 tries to move so that the portion clamped by the friction members 67 and 68 moves from the first portion 36B side to the second portion 36C side. Since the distance between the friction members 67 and 68 is gradually reduced in the direction opposite to the moving direction, the locking wire 36 is connected to the first lever member 61 and the second lever member 62. Can be more effectively prevented from sliding move.

  In the present embodiment, when the folded portion 36A of the locking wire 36 is clamped and locked by the friction members 67 and 68, as shown in FIG. One guide member 60A of the guide members 60 and the second lever member 62 form a bypass portion 36F that is not linear. For this reason, even if the obstacle 34 is a hard object that does not dent deform or hardly dent deforms, the second portion 36C of the locking wire 36 faces downward by forming the detour portion 36F in the locking wire 36. It can be pulled, and a large tension can be applied to the second portion 36C.

  As described above, the sliding movement of the locking wire 36 relative to the first lever member 61 and the second lever member 62 is prevented by the friction members 67 and 68, and the second portion 36 </ b> C of the locking wire 36 is prevented. When a large downward tension is applied, the end of the second portion 36C of the lock wire 36 is connected to the link member 43 provided in the second processing device 38 of FIG. 43 starts to rotate in the D direction around the shaft 42A.

  FIG. 18 shows a state in which the link member 43 is slightly rotated in the D direction around the shaft 42A from the state of FIG. 16, and when the link member 43 is slightly rotated in the D direction around the shaft 42A in this way. Since the actuator 109 of the electric switch 108 that has been in contact with the upper surface of the link member 43 is activated, a signal from the electric switch 108 is input to the control device 26 in FIG. Thereby, the control device 26 stops energization to the solenoid 24 energized until that time of the switch 13 shown in FIG. 2 for a short time to electrically turn on the brake means 19 of the switch 13. And when the closing movement of the shutter curtain 1 is performed by rotating the winding shaft 11 of FIG. 1 in the normal direction by energizing the coil 25 of the opening / closing machine 13, energizing the coil 25 is performed for a short time. After stopping the shutter curtain 1 in contact with the obstacle 34 for a short time set by the control device 26, the control device 26 brakes by energizing the solenoid 24. By electrically turning off the means 19 and energizing the coil 25, the shutter curtain 1 is reversed and raised by the reverse rotation of the winding shaft 11.

  When the shutter curtain 1 is turned upside down in this way, the shutter curtain 1 is separated from the obstacle 34, so that the tension force acting on the second portion 36C of the lock wire 36 starts to decrease or disappear, When the tension force starts to decrease or disappear in this way, the link member 43 of the second processing device 38 shown in FIG. 18 rotates in the direction C in FIG. 16 by the urging force accumulated by the torsion coil spring 101. It will return. As a result, the actuator 109 of the electric switch 108 also returns to the original state shown in FIG. 16, and therefore the control device 26 of FIG. The energization to the solenoid 24 of the opening / closing machine 13 is interrupted to turn on the brake means 19 and the energization to the coil 25 is interrupted to stop the reversal of the shutter curtain 1.

  For this reason, the shutter curtain 1 is stopped at a position where it is slightly reversed and raised, so that it is possible to perform operations such as removing the obstacle 34 from the entrance 2 shown in FIG. Further, by operating the operation device 30, the shutter curtain 1 can be closed and opened as a shutter curtain of the management shutter device.

  As described above, when the downward tension force acts on the second portion 36C of the locking wire 36 and the link member 43 of the second processing device 38 is slightly rotated in the direction D in FIG. The rotating member 42 of the device 38 is also slightly rotated in the D direction by the pressing force from the roller 107 that is in contact with the contacted surface 42B of the rotating member 42. As can be seen from the description, since the rotary damper 102 does not function as the delay device 99, a downward tension acts on the second portion 36C of the locking wire 36, so that the link member 43 immediately rotates in the D direction. By this rotation, the electric switch 108 can be actuated immediately.

  In the present embodiment, the delay device 99 using the rotary damper 102 and the automatic closing device 32 shown in FIGS. 20 and 21 are arranged apart from each other, and the delay device 99 is used together with the rotary damper 102. The rotating member 42 constituting the slide member 120 and the slide member 120 constituting the automatic closing device 32 are connected to each other via the first control wire 111. The first control wire 111 is delayed. The first control wire 111, which is a flexible connecting member for connecting the device 99 and the automatic closing device 32 and also serves as a string-like member, is shown in FIG. Therefore, even if the rotating member 42 is slightly rotated in the D direction and the first control wire 111 is slightly pulled by this rotation, the bent portion 111A is provided. The amount of bending is only reduced or eliminated, and a slight rotation of the rotating member 42 in the direction D does not affect the slide member 120 of the automatic closing device 32 shown in FIGS. .

  That is, even if the rotation member 42 is slightly rotated in the D direction, the slide member 120 does not slide from the position shown in FIG. 21 and maintains this position.

  Further, as described above, when the tension force acting on the second portion 36C of the locking wire 36 starts to decrease or disappear due to the reversal rise of the shutter curtain 1, the link member 43 of the second processing device 38 becomes When rotating back in the direction C in FIG. 16 due to the biasing force accumulated in the torsion coil spring 101, the pivoting member 42 of the second processing device 38 also moves in the direction C in FIG. The rotation return of the rotation member 42 is performed at a low speed because the rotary damper 102 functions as the delay device 99. At this time, the roller 107 is in contact with the contact surface of the rotation member 42. Since the link member 43 is separated from the rotation member 42 in order to leave the link member 42B, in other words, the link member 43 can be quickly rotated and returned in the C direction. Therefore, also be returned to the original condition shown an actuator 109 of the electrical switch 108 in FIG. 16, it is possible to quickly.

  The electrical switch 108 according to the present embodiment is a B-contact type electrical switch. In other words, no electricity flows through the normal electrical switch 108 shown in FIG. Electricity will flow through the electrical switch 108 in the state shown. In this way, when the electrical switch 108 is a B contact type electrical switch, the rotation member 42 is slightly rotated in the direction D more reliably than when the electrical switch 108 is an A contact type electrical switch. Since it becomes possible to transmit a signal from the switch 108 to the control device 26, the control of the control device 26 performs an operation of raising the reverse movement after temporarily stopping the closing shutter curtain 1 for a short time as described above. This can be done more quickly after the shutter curtain 1 comes into contact with the obstacle 34.

  As can be seen from the above description, according to the present embodiment, when the shutter device of the present embodiment is a management shutter device that opens / closes and stops moving by the operation of the operation device 30, the shutter being closed and moving When the curtain 1 abuts against the obstacle 34, this abutment can be detected by the electric switch 108 via the lock wire 36 and the link member 43 which are string-like members. For this reason, by electrically controlling the switch 13 with the control device 26 that receives the signal from the electric switch 108, the brake means 19 of the switch 13 is turned on electrically for a short time, and the shutter curtain 1 The shutter curtain 1 can be turned upside down by temporarily stopping and turning off the brake means 19 and energizing the coil 25.

  Further, when the tension force acting on the second portion 36C of the lock wire 36 is reduced or disappeared by the reversal and raising of the shutter curtain 1, it is not affected by the low-speed return rotation of the rotation member 42. Since the link member 43 can be quickly returned and rotated, the electric switch 108 can be quickly returned to the original state, and immediately after the start of the reverse rise of the shutter curtain 1 by this early return action. The control of stopping the shutter curtain 1 can be performed by the control device 26 to which a signal from the electric switch 108 is input.

  When the tension applied to the second portion 36C of the lock wire 36 is reduced or disappeared by the upward movement of the shutter curtain 1, the shutter 26 is controlled by the control device 26 to which a signal from the electric switch 108 is input. The control performed for 1 is not limited to the control for stopping the reversal and raising of the shutter curtain 1 as described above.

  That is, when the tension force acting on the second portion 36C of the lock wire 36 is reduced or disappeared by the reversal rise of the shutter curtain 1, the shutter curtain is controlled by the control device 26 to which a signal from the electric switch 108 is input. The control performed for 1 may be a control for causing the shutter curtain 1 that has been reversed and raised to stop the reverse rise and then restart the closing movement, or without raising the shutter curtain 1 that is in contact with the obstacle 34 by being reversed and raised. In the case of stopping, it may be a control for releasing the stop and restarting the closing movement.

  In a building where the shutter device of this embodiment is installed, when a disaster such as a fire occurs when the shutter curtain 1 is fully open and stopped, a signal from a sensor that detects the disaster is input. Since the control device (this control device may be combined with the control device 26 of FIG. 1), the solenoid 126 of the automatic closing device 32 of FIG. 21 is energized and the solenoid 126 is excited. The plunger 127 of the solenoid 126 moves backward against the spring 128. As a result, the bending lever member 129 rotates in the direction opposite to the G direction in FIG. 21 around the central axis 129A against the springs 131 and 132. The state at this time is shown in FIG. When the bending lever member 129 rotates about the central axis 129 </ b> A in the direction opposite to the G direction, the roller 130 of the bending lever member 129 escapes from the recess 120 </ b> B of the sliding member 120. The forward movement is stopped when the front end of the connecting member 138 comes into contact with the above-described rising portion 110B of the machine casing 110 of the automatic closing device 32. The position of the front end of the slide member 120 at this time is the I position that is the foremost position among the three positions H, I, and J shown in FIG. 21, as shown in FIG.

  The signal from the above-described sensor that detects the occurrence of a disaster such as a fire is sent to the control device 26 in FIG. 1, and the control device 26 that has received this signal subsequently operates the electric switch 108 in FIG. However, the signal sent from the electrical switch 108 is invalidated.

  When the slide member 120 moves forward to the position I in FIG. 22, the actuator 136 of the micro switch 135 is disengaged from the position of the dog member 137 attached to the slide member 120, so that the actuator 136 is protruded and moved by the biasing force of the spring. In response to the signal from the micro switch 135 that has performed the above, the control device stops energizing the solenoid 126.

  When the energization of the solenoid 126 is stopped, the plunger 127 protrudes from the solenoid 126 by the spring force of the spring 128, and the bending lever member 129 is centered on the central axis 129A by the spring force of the springs 131 and 132 in the G direction of FIG. To turn. Since the slide member 120 at this time has advanced to the limit of movement in which the front end of the slide member 120 reaches the I position, the roller 130 of the bending lever member 129 slides as shown in FIG. It hits the aforementioned inclined surface 120C of the member 120. For this reason, the protruding movement of the plunger 127 and the rotation of the bending lever member 129 about the central axis 129A in the G direction stop halfway.

  When the slide member 120 of the automatic closing device 32 advances as described above, the operating member 122 provided at the front end of the slide member 120 is connected to the opening / closing machine 13 via the operated member 123 shown in FIG. In order to press the first portion 31A of the lever member 31 in the direction A in FIG. 3, as described above, the first portion 31A swings in the A direction using the second bent portion 31D of the lever member 31 as a fulcrum. As a result, the brake shaft 21 and the brake drum 22 of the brake means 19 of the opening / closing machine 13 slide in the A ′ direction which is the same direction as the A direction. Turned off. For this reason, the shutter curtain 1 that is fully open is closed and moved downward while rotating the winding shaft 11 by the weight of the seat plate 1B and the like below the winding shaft 11. The above-described drive shaft 14 of the opening / closing machine 13 also freely rotates via the drive force transmission means 12 and the shutter curtain 1 is fully closed, whereby a disaster prevention zone is formed by the shutter curtain 1.

  Further, when a person discovers that a disaster such as a fire has occurred, this person is arranged in the operating device 30 shown in FIG. 1 and is connected to the end of the second control wire 112 described above. The second control wire 112 is pulled by a manual operation member such as a lever member. As a result, the plunger 127 of the solenoid 126 moves backward, so that even before the solenoid 126 is energized and excited, the bending lever member 129 is centered on the central axis 129A even when the solenoid 126 is energized and excited. 21, the roller 130 of the bending lever member 129 escapes from the concave portion 120 </ b> B of the slide member 120, and the slide member 120 moves forward by the spring force of the spring 121.

  For this reason, in the present embodiment, the second control wire 112 spanned between the automatic closing device 32 and the operation device 30 is a pull operation member that is pulled by the operation device 30. Even in the manual operation using the second control wire 112, the brake means 19 of the switch 13 can be mechanically turned off and the shutter curtain 1 that has been fully opened can be closed and moved by its own weight to be fully closed. .

  When the slide member 120 moves forward to the I position shown in FIG. 23, the bending portion 111A provided on the first control wire 111 shown in FIG. 20 disappears.

  In the present embodiment, as shown in FIG. 1, the operating device 30 includes a switch 13 and an automatic switch among the building housings 3 such as the left and right walls arranged on both sides in the width direction of the shutter curtain 1. It is arranged in one building housing 3A that is close to the closing device 32. For this reason, the length of the second control wire 112 that is stretched between the automatic closing device 32 and the operation device 30 and is a pulling operation member that is pulled by the operation device 30 can be shortened. . Accordingly, when the second control wire 112 is pulled by the manual operation member such as the lever member described above, compared to the case where the operating device 30 is arranged in the other building housing 3B among the building housings 3 such as the left and right walls. Can be instantaneously input to the automatic closing device 32, so that the brake means 19 of the switch 13 can be instantaneously turned off, and the closing movement of the shutter curtain 1 that has been fully opened can be quickly performed. Can be started.

  When the shutter curtain 1 reaches the fully closed position and a disaster such as a fire is resolved, the shutter curtain 1 is disposed on the operating device 30 shown in FIG. The third control wire 113 is pulled by a manual operation member such as a lever member. Accordingly, since the third control wire 113 is connected to the slide member 120 of the automatic closing device 32, the slide member 120 moves backward against the spring force of the spring 121. For this reason, the slide member 120 returns from the position shown in FIG. 23 to the initial position where the front end becomes the H position in FIG. Further, when the slide member 120 returns to this initial position, the bending lever member 129 rotates in the direction G in FIG. 21 by the spring force of the springs 131 and 132 about the central axis 129A. As shown in FIG. 21, the roller 130 is fitted into the recess 120B of the slide member 120, and the slide member 120 stops in a state where the front end of the slide member 120 reaches the H position. Thereby, the automatic closing device 32 returns to the initial state before the occurrence of a disaster such as a fire.

  When the slide member 120 returns to the initial position, the brake shaft 21 and the brake drum 22 of the brake means 19 of the opening / closing machine 13 are moved in the direction opposite to the A ′ direction by the spring 23 described above with reference to FIG. 19 is mechanically turned back on. Thereafter, by operating the above-mentioned “open” button provided in the operating device 30, the shutter curtain 1 opens and moves to the fully open position as described above.

  As described above, the solenoid 126 of the automatic closing device 32 is energized and excited by the control device that receives a signal from a sensor that detects a disaster such as a fire, or is connected to the end of the second control wire 112. The second control wire 112 is pulled by a manually operated member such as a lever member, and thereby the brake means 19 of the switch 13 is turned off, and the shutter curtain 1 is closed and moved downward from the fully opened position. The time is when the shutter device of this embodiment is a shutter device for disaster prevention. At this time, the brake means 19 of the switch 13 shown in FIG. 3 is a brake means that is mechanically turned on and off by the slide of the slide member 120 of the automatic closing device 32, as is apparent from the above description. ing.

  In addition, when the shutter device according to this embodiment is a disaster prevention shutter device and the shutter curtain 1 is closed and moved downward from the fully opened position, in other words, the automatic closing device 32 is shown in FIG. When the shutter curtain 1 is closed and moved downward from the fully open position and the obstacle 34 shown in FIG. 1 exists below the shutter curtain 1 in the closing movement direction. In the middle of the closing movement of the shutter curtain 1, the curtain sub-portion 71B arranged at the front end of the shutter curtain 1 in other words forms the lower part of the seat plate 1B of the shutter curtain 1. The above-mentioned movable part 70B is in contact with the obstacle 34. The obstacle is an evacuee who evacuates from a disaster such as a fire.

  Thus, even when the shutter device of the present embodiment is a disaster prevention shutter device, the mechanical coupling device 39 is the same as when the shutter device according to the present embodiment is the above-described management shutter device. Because the friction members 67 and 68 of the first lever member 61 and the second lever member 62 sandwich and lock the folded portion 36A of the locking wire 36, the second portion 36C of the locking wire 36 which is a tension acting member. The downward tension force due to the weight of the curtain main portion 71A of the shutter curtain 1 acts on the shutter curtain 1.

  Accordingly, the link member 43 of the second processing device 38 rotates in the direction D in FIG. 16, and the rotation member 42 in which the roller 107 of the link member 43 is in contact with the contacted surface 42B also rotates in the direction D. To do. When the link member 43 is slightly rotated in the direction D, the actuator 109 of the electric switch 108 shown in FIG. 16 operates. At this time, as described above, the signal input from the electric switch 108 to the control device 26 is Since the control device 26 is invalidated, the control device 26 does not perform control for causing the opening / closing device 13 to reversely lift the shutter curtain 1.

  For this reason, the link member 43 is rotated in the direction D in FIG. 16 by the downward tension acting on the second portion 36C of the locking wire 36 to the state in FIG. 19 through the state in FIG. The first control wire 111 is pulled longer than when the shutter device of the present embodiment is a management shutter device. At this time, the bending portion 111A shown in FIG. 20 has disappeared, and the slide member 120 of the automatic closing device 32 is moved to the J position shown in FIG. 21 by the pulling action of the first control wire 111. fall back. That is, the slide member 120 stops at the J position intermediate between the H position and the I position. The state at this time is shown in FIG. At this time, the position of the slide member 120 with which the roller 130 of the bending lever member 129 is in contact has moved in the length direction of the slide member 120, which is the slide direction of the slide member 120, as compared with FIG. 23. The roller 130 is still in contact with the inclined surface 120C described above.

  Further, since the position of the front end of the slide member 120 at this time is retracted from the I position to the J position, the operating member 122 of the slide member 120 moves the first portion 31A of the lever member 31 of FIGS. The load pressed in the A direction in FIG. 3 is released. For this reason, the brake means 19 of the switch 13 is mechanically switched from off to on. When the brake means 19 is turned on, the drive shaft 14 of the opening / closing machine 13 cannot rotate, so that the winding shaft 11 to which the upper end of the shutter curtain 1 is coupled cannot also rotate.

  Therefore, the shutter curtain 1 that is in contact with the obstacle 34 closes and stops moving at the contact position. This stop can be achieved by the mechanical coupling device 39 provided with the first lever member 61 and the second lever member 62 for locking the locking wire 36 with the friction members 67 and 68, or the second processing which is also mechanical. It is performed by a mechanical structure constituted by the device 38, the slide member 120 as a member of the automatic closing device 32 that slides mechanically, the brake means 19 of the switch 13 that is mechanically turned on, and the like. For this reason, after the shutter curtain 1 is closed and started moving, the building in which the shutter device according to the present embodiment is installed is blacked out due to the occurrence of a disaster such as a fire or other reasons. However, the shutter curtain 1 that is in contact with the obstacle 34 during the closing movement can be mechanically stopped.

  In the present embodiment, as described with reference to FIG. 1, the mechanical coupling device 39 and the unit structure 45 constituting the mechanical obstacle detection device 35 described above are arranged at the center position in the width direction of the shutter curtain 1. It is not arrange | positioned at B, but is arrange | positioned from this center position B in the position displaced to the one side in which the switch 13 and the automatic closing device 32 are arrange | positioned among the width directions of the shutter curtain 1. FIG. . For this reason, the second processing device 38 and the automatic closing device 32 are arranged on the same side in the width direction of the shutter curtain 1 with respect to the central position B. For this reason, the second processing device 38 and the automatic closing device 32 are automatically closed. The length of the first control wire 111 that is wired between the devices 32 and is a tension acting member that acts on the tension described above can be shortened, similarly to the locking wire 36. Therefore, when the closing shutter curtain 1 comes into contact with the obstacle 34, the tension force acting on the first control wire 111 is input to the automatic closing device 32 in a short time via the second processing device 38. As a result, the brake means 19 of the switch 13 can be quickly mechanically turned on.

  Further, in the present embodiment, as shown in FIG. 1, the unit structure 45 including the second processing device 38 and the automatic closing device 32 are spaced from the center position B in the width direction of the shutter curtain 1 by this width. The unit structure 45 and the automatic closing device 32 are not arranged at the same position in the width direction of the shutter curtain 1 and are automatically separated from the unit structure 45. In the closing device 32, the unit structure 45 is disposed closer to the center position B in the width direction of the shutter curtain opening / closing body than the automatic closing device 32. For this reason, in the present embodiment, the mechanical coupling device 39 connected to the unit structure 45 via the locking wire 36 is also located at the center position B in the width direction of the shutter curtain 1 rather than the automatic closing device 32. It is arranged at a close position. According to this, regardless of the position in the width direction of the shutter curtain 1 that the shutter curtain 1 in the middle of the closing movement comes into contact with the obstacle 34, the shutter curtain 1 and the lock wire 36 are connected to the mechanical coupling device 36. Can be more reliably performed to bring them into a mechanically coupled state.

  Further, the unit structure 45 is disposed closer to the center position B in the width direction of the shutter curtain opening / closing body than the automatic closing device 32, so that the automatic closing device 32 has a width of the shutter curtain 1 wider than the unit structure 45. It is arranged at a position far from the central position B in the direction. The position of the automatic closing device 32 is a member for supporting the shutter curtain 1 so that the shutter curtain 1 can be opened and closed, specifically, a winding shaft 11 that opens and closes the shutter curtain 1 by winding and unwinding the shutter curtain 1. Of the shutter box 8 serving as a support member for supporting, the position is close to the side surface portion 8B. Since the opening / closing machine 13 is attached to the side surface portion 8B via the bracket member 15 and the automatic closing device 32 is attached to the opening / closing machine 13, the automatic closing device 32 is more shuttered than the unit structure 45. By disposing the automatic closing device 32 at a position far from the central position B in the width direction of the curtain 1, the automatic closing device 32 is effectively disposed on the side surface portion 8 </ b> B of the shutter box 8 via the bracket member 15 and the switch 13. Can do.

  As described above, after the closing shutter curtain 1 comes into contact with the obstacle 34 and the brake means 19 of the switch 13 is mechanically turned on to stop the closing movement of the shutter curtain 1, the obstacle 34 When removed, the curtain sub-portion 71B of the shutter curtain 1 is lowered, so that the lock wire 36 is clamped by the friction members 67 and 68 of the first lever member 61 and the second lever member 62 of the mechanical coupling device 39. The lock is released, and the mechanical coupling state between the shutter curtain 1 and the locking wire 36 by the mechanical coupling device 39 is also released. As a result, the tension force of the locking wire 36 disappears. For this reason, the link member 43 and the rotating member 42 of the second processing device 38 on which the return force by the torsion coil spring 101 and the coil spring 100 of FIG. 16 is rotated in the C direction of FIG. 16, and the slide member 120 of the automatic closing device 32 that has been pulled in the backward direction by the first control wire 111 by the rotation of the rotating member 42 in the C direction is a spring. By 121, the front end moves forward from the J position shown in FIG. 24 to the I position shown in FIG. For this reason, the brake means 19 of the opening / closing machine 13 is mechanically switched again from on to off, and the shutter curtain 1 resumes its closed movement.

  When the rotating member 42 of the second processing device 38 rotates in the direction C in FIG. 16, the pinion gear 103 of the rotary damper 102 rotates in the direction E in FIG. Resistive force is generated by viscous fluid. Therefore, the position of the front end of the slide member 120 shifts from the J position shown in FIG. 24 to the I position shown in FIG. 23, and the brake means 19 of the switch 13 is mechanically switched from on to off by this shift. This is not done instantaneously due to the delay action of the damper 102. Therefore, the shutter curtain 1 closing and resuming the movement by removing the obstacle 34 starts with a time delay from the removal of the obstacle 34, and therefore, the removal operation of the obstacle 34 has a time margin. It can be carried out.

  As can be seen from this description, the damper 102 and the rotating member 42 in the second processing device 38 are the delay device 99 for delaying the restart when the shutter curtain 1 resumes the closing movement after the obstacle 34 is removed. It is what constitutes.

  In order to prevent the viscous fluid from dropping from the unit structure 45 shown in FIG. 4 even if the viscous fluid leaks from the damper 102 of the delay device 99, for example, the base of the unit structure 45 is used. By providing a rising wall around the member 44, the base member 44 may have a dish shape.

  Further, this delay device may employ, for example, mechanical means including a mainspring type timer instead of the damper 102. According to this mechanical means, unlike the viscous fluid damper 102, the delay time can be set more accurately without being affected by the environmental temperature.

  Then, after the shutter curtain 1, which has resumed the closing movement, is fully closed, the third control wire 113 is automatically closed by pulling it with the above-described manual operation member such as a lever member disposed in the operation device 30. Since the slide member 120 of the device 32 performs a return movement in which the position of the front end returns to the H position in FIG. 21, the entire automatic closing device 32 returns to the initial state in FIG. 21.

  In the above, when the locking wire 36 is locked by the mechanical coupling device 39, a large downward tensile amount may be generated in the second portion 36C of the locking wire 36 that is a tension acting member. Such a large downward tensile amount is, for example, a large deflection in the vertical direction on the seat plate 1B forming the lower end of the shutter curtain 1 because the width dimension in the left-right direction, which is the width dimension of the shutter curtain 1, is large. This occurs when the shutter curtain 1 reaches the floor 4 in FIG. 1 and is fully closed. That is, when the seat plate 1B is largely bent in the vertical direction, a part of the seat plate 1B comes into contact with the floor 4 first, and at this time, the above-described folded portion 36A of the lock wire 36 is used as a mechanical coupling device. Since the lock wire 36 and the shutter curtain 1 are coupled with each other by being locked at 39, a part of the seat plate 1B that is first landed on the floor 4 and a position where the mechanical coupling device 39 is disposed are the shutter curtain. 1, the other part of the seat plate 1B is delayed and landed on the floor 4 so that the second part 36C of the lock wire 36 has a vertical direction of the seat plate 1B. A large downward tensile amount corresponding to a large amount of deflection is generated.

  Further, the large downward pulling amount causes the position of the shutter curtain 1 in contact with the obstacle 34 and the position of the shutter curtain 1 where the mechanical coupling device 39 is arranged to be greatly shifted in the left-right direction, and the obstacle Even after the shutter curtain 1 comes into contact with 34, it also occurs when the location of the shutter curtain 1 where the mechanical coupling device 39 is arranged moves greatly downward.

  When a large downward pulling amount is generated in the second portion 36C of the locking wire 36, as can be seen from the above description, the automatic closing device 32 for turning on and off the brake means 19 by reciprocating sliding is provided. The slide member 120 slides excessively rearward, and the front end position of the slide member 120 becomes the H position instead of the J position in FIG. 21, whereby the roller 130 of the bending lever member 129 is As in the case of FIG. 21, the brake means 19 cannot be returned to the off state even when the obstacle 34 is removed by fitting into the recess 120 </ b> B of the slide member 120.

  For this reason, the shutter device according to the present embodiment is devised to function effectively when a large downward tensile amount acts on the second portion 36 </ b> C of the locking wire 36.

  That is, a long hole 106 is formed in the link member 43 of FIG. 16, and the pin constituting the connecting portion 43 </ b> A between the second portion 36 </ b> C of the locking wire 36 and the link member 43 is formed in the long hole 106. 105 is inserted and, as will be apparent from the description below, the elongated hole 106, which serves as a guide for guiding the movement of the connecting portion 43A, has a bending angle between the first portion 106A and the second portion 106B. Are connected in a V shape or substantially V shape, and the bending angle is greater than 90 degrees. And in this embodiment, when the shutter curtain 1 in the closing movement comes into contact with the obstacle 34, the rotating member 42 and the link member 43 change from the state of FIG. 16 or 18 to the state of FIG. The extension part 101B which is the end part of the torsion coil spring 101 which is an elastic member for applying the rotational force in the C direction to the link member 43 is the second part of the link member 43 and the lock wire 36. Since it is locked to the pin 105 constituting the connecting portion 43B with 36C, the connecting portion 43B is the same as in FIGS. 16 and 18 due to the elastic force of the extending portion 101B of the torsion coil spring 101. Of the first portion 106A and the second portion 106B of the long hole 106, the first portion 106A is stopped or almost stopped at the position of the first portion 106A.

  When a large downward tensile amount is generated in the second portion 36C of the locking wire 36, the link member 43 and the rotating member 42 according to the present embodiment are not rotated from the state shown in FIG. Instead, the connecting portion 43A moves from the first portion 106A to the second portion 106B of the elongated hole 106 while resisting the elastic force of the extending portion 101B of the torsion coil spring 101. In other words, the connecting portion 43A Then, it moves relative to the link member 43 while resisting the elastic force of the extension part 101B of the torsion coil spring 101, and the connecting part 43A is connected to the second part 106B as shown by the two-dot chain line in FIG. The end is reached.

  As can be seen from the above description, the link member 43 is an intermediate member disposed between the locking wire 36 and the automatic closing device 32. For this reason, out of the above-described large tensile amount, a reference to be described later is provided. A portion larger than the tensile amount is absorbed by the long hole 106 formed as a guide portion in the intermediate member, and as a result, the slide member of the automatic closing device 32 via the first control wire 111 It is possible to prevent 120 from sliding excessively backward. That is, in the shutter device according to the present embodiment, when a large tensile amount is generated in the locking wire 36 that is the tension acting member, the connecting portion 43A can move with respect to the link member 43. The sliding member 120 of the automatic closing device 32 can be prevented from sliding excessively rearward, and a large tension force can be prevented from acting on the second portion 36C of the locking wire 36 and the first control wire 111.

  As can be seen from the above, the large pulling amount of the locking wire 36 serving as the tension acting member is a pulling amount larger than the reference pulling amount, and the reference pulling amount is the locking wire. The connecting member 43A of the 36 does not move or hardly moves with respect to the link member 43, and the link member 43 performs a motion of turning in the D direction about the shaft 42A of FIG. The large pulling amount of the locking wire 36 causes the link member 43 to move in the D direction around the shaft 42A, and the connecting portion 43A of the locking wire 36 has the link member 43. On the other hand, the amount of tension is generated by moving along the long hole 106.

  Further, as described above, the automatic closing device 32 has the slide member 120 for turning on and off the brake means 19 by reciprocating sliding, and the large pulling amount of the locking wire 36 is turned on. Further, the lock wire 36 has a tensile amount that further retracts the slide member 120 to a position where the brake means 19 cannot be returned to the off state.

  Further, according to the present embodiment, the portion to which the connecting portion 43A moves when a large tensile amount is generated in the second portion 36C of the locking wire 36 is, as shown in FIG. The second portion 106B is vertical or substantially vertical, and the direction in which the second portion 106B extends is the same as or substantially the same as the direction of the tension force acting on the second portion 36C of the locking wire 36. Therefore, the connecting portion 43A can smoothly reach the end of the second portion 106B by the large amount of tension described above.

  Furthermore, in the state shown in FIG. 19 before a large amount of tension is applied to the second portion 36C of the locking wire 36, the elastic force of the extending portion 101B of the torsion coil spring 101 includes the moving direction of the connecting portion 43A. Since there is a component in the direction opposite to the extending direction of the long hole 106, the movement of the connecting portion 43A along the long hole 106 is prevented by the torsion coil spring 101. The position of the connecting portion 43A can be stopped at the position shown in FIGS.

  Further, in the entire range in which the connecting portion 43A is guided to the long hole 106 and moves to the position indicated by the two-dot chain line in FIG. 19, the extending portion 101B of the torsion coil spring 101 is always connected to the connecting portion 43A. In order to maintain the contact state, when the connecting portion 43A is guided and moved by the long hole 106, the torsion coil spring 101 has an elastic return for returning the connecting portion 43A to the original position before the movement. Therefore, when the shutter curtain 1 opens and moves, and the above-described large tensile amount disappears, the connecting portion 43A is long due to the elastic return force accumulated in the torsion coil spring 101. The hole 106 naturally returns to its original position in the first portion 106A.

  Further, the torsion coil spring 101 is an elastic member for applying a rotational force in the direction C in FIG. 1 to the link member 43 that is an intermediate member disposed between the locking wire 36 and the automatic closing device 32. For this reason, the elastic member having a component in the direction opposite to the extending direction of the long hole 106 is applied to the connecting portion 43A by the combined use of the elastic member. It is possible to realize the action and to return the connecting portion 43A to the original position before the movement.

  In the present embodiment, the first connecting member is a connecting member that connects the rotating member 42 that constitutes the delay device 99 together with the rotary damper 102 and the slide member 120 that constitutes the automatic closing device 32. Since the control wire 111 is provided with the bending portion 111A shown in FIG. 20 in a normal state, the slide of the automatic closing device 32 can be performed when the shutter curtain 1 being moved closes against the obstacle 34. The member 120 can switch the brake means 19 of the opening / closing machine 13 from OFF to ON more reliably.

  This will be described in detail. When the first control wire 111 is not provided with the bending portion 111A, the control wire 111 is tensioned to be bridged between the delay device 99 and the automatic closing device 32. May cause the first control wire 111 to bend due to secular change or the like. According to this, the shutter curtain 1 that is moving in close contact with the obstacle 34, so that the advance limit of the automatic closing device 32 is reached. When the slide member 120 that has reached is retracted by the pulling action of the first control wire 111, there is a risk that the amount of movement of the retraction is reduced by the amount of bending. As a result, the brake means 19 of the switch 13 is turned off. It may be difficult to switch on. However, by providing the first control wire 111 with the bending portion 111A in the normal state, it is possible to prevent the control wire 111 from being bent due to secular change or the like. When it comes into contact with the object 34, it is possible to more reliably switch the brake means 19 of the opening / closing machine 13 from OFF to ON by the slide member 120 of the automatic closing device 32.

  Although the above description has been made when the above-described disaster such as a fire occurs when the shutter curtain 1 is fully opened and stopped, the shutter curtain 1 is opened by the operation of the operation device 30 in FIG. When moving, when stopping, when closing, when stopping against an obstacle during closing, or when reaching the fully closed position If a disaster such as a fire occurs and the solenoid 126 of the automatic closing device 32 is energized and energized by the control device to which a signal from the sensor that has detected the disaster is input, or if a disaster such as a fire occurs Even when the discovered person pulls the second control wire 112, the slide member 120 reaches the I position, which is the foremost position, as shown in FIGS.

  In other words, the brake means 19 of the opening / closing machine 13 is controlled by both the operating device 30 and the automatic closing device 32, and the operating device is either turned on or off. Even when the slide member 120 of the automatic closing device 32 has advanced to the I position even when the state is electrically controlled by the brake 30, the brake means 19 is turned off. The brake means 19 can be turned off in preference to the mechanical control by the automatic closing device 32. And the operation | movement mentioned above regarding the rotation member 42 used as the 1st operation member and the link member 43 used as the 2nd operation member can be performed as predetermined, without generating inconveniences, such as a contradiction. .

  Next, a shutter device according to another embodiment will be described. The entirety of this shutter device is shown in FIG. 25, and this shutter device is also a shutter device for both management and disaster prevention. In the following description, devices, members, means, and the like corresponding to the devices, members, means, and the like in the shutter device in the above-described embodiment are denoted by the same reference numerals as those used in the above-described embodiment. The description about is omitted.

  In the shutter device shown in FIG. 25, the device 233 mounted on the upper part of the opening / closing machine 13 is configured such that a delay device and an automatic closing device are arranged adjacent to each other. Therefore, the device 233 is a composite device having a function as a delay device and a function as an automatic closing device. Therefore, in the shutter device of FIG. 25, no delay device is installed in the lintel 16, and the lintel 16 includes an apparatus corresponding to the first processing device 37 shown in FIG. One end portion of the locking wire 236 is connected, and a winding device 237 for winding the locking wire 236 so as to be unwound is installed.

  As described above, in this embodiment, the delay device and the automatic closing device are arranged adjacent to each other as the composite device 233, so that the device can be shared and the overall size of the shutter device can be reduced accordingly. .

  The other end portion of the lock wire 236 extends to the delay device of the composite device 233, and the shutter curtain 1 that is being closed is in contact with the obstacle 34 on the lock wire 236 that is a string-like member. When it does, the weight of the curtain main part 71A acts as a tension force among the weight of the shutter curtain 1. Of the locking wire 236, a portion from the winding device 237 to the mechanical coupling device 39 disposed on the shutter curtain 1 is a first portion 236 </ b> B, and from the mechanical coupling device 39 to the composite device 233. A portion up to the delay device is a second portion 236C, and a portion inserted into the mechanical coupling device 39 is a folded portion as in the above embodiment.

  26 is a plan view showing the internal structure of the composite device 233, and FIG. 27 is a front view of the delay device 299 of the composite device 233. As shown in FIG. 26, an auxiliary member 310A is provided in the machine casing 310 of the composite apparatus 233, and the auxiliary member 310A has a rotating member 242 and a link member 243, as shown in FIG. As shown in FIG. 26, the rotation center portion of the rotation member 242 and the link member 243 is a stepped shaft 242A fixed to the auxiliary member 310A. . For this reason, the rotation member 242 and the link member 243 are coaxial rotation members formed by the stepped shaft 242A. The end of the second portion 236C of the lock wire 236 is connected to the link member 243, and the link member 243 has the link member 243 centered on the shaft 242A in the direction P in FIG. A spring 301 serving as an urging means for urging and urging the second portion 236C of the locking wire 236 in the pulling direction is disposed. As shown in FIG. 26, the spring 301 is a torsion coil spring in which a coil portion is wound around a shaft 242A, and one extension portion 301A is engaged with a pin 310C provided on the auxiliary member 310A. It has been stopped.

  The rotating member 242 is urged to rotate by the torsion coil spring 300 about the shaft 242A in the direction P in FIG. The spring 300 serves as a biasing means for biasing the rotation member 242 in the P direction.

  As shown in FIG. 27, the second portion 236C of the lock wire 236 is guided horizontally or substantially horizontally to the link member 243 by the guide roller 350, and the guide roller 350 is shown in FIG. As shown, the auxiliary member 310A is disposed.

  29 is a cross-sectional view taken along line S29-S29 in FIG. As shown in FIG. 29, the connecting portion 243A between the link member 243 and the lock wire 236 is configured by a pin 305, and the pin 305 is formed on the link member 43. The long hole 306 is slidably inserted into the long hole 306, and the long hole 306 has a V shape or a substantially V shape in which the first portion 306A and the second portion 306B are connected with a bending angle larger than 90 degrees. Yes. In addition, the other extending portion 301B of the torsion coil spring 301 is locked to the pin 305, and thereby, the link member 243 is given a rotational biasing force in the direction P in FIG. 27 about the shaft 242A. Further, a roller 307 is rotatably attached to one end portion of the pin 305 protruding from the long hole 306, and a contacted portion 242B in which the roller 307 contacts the side surface is formed on the rotating member 242. Has been. The abutted portion 242B is formed as a thick portion formed by increasing the thickness of a part of the rotating member 242 or a plate-like member attached to the rotating member 242. FIG. 28 is a plan sectional view of FIG. 27 showing portions of the rotating member 242 and the link member 243 in order to show the relationship between these rollers 307 and the contacted portion 242B.

  As shown in FIG. 27, an electric switch 308 is disposed in the auxiliary member 310 </ b> A close to the link member 243, and an actuator 309 of the electric switch 308 is in contact with the upper side surface of the link member 243. Since the electrical switch 308 is connected to the control device 26 shown in FIG. 25 by an electric circuit, as in the above embodiment, the signal from the electrical switch 308 is sent to the control device 26.

  Further, as shown in FIG. 27, gear teeth 242C are formed on a part of the outer peripheral portion of the rotating member 242, and therefore, the rotating member 242 has gear teeth 242C formed on a part thereof. It is a sector gear. In addition, a rotary damper 302 is attached to the auxiliary member 310A, and the damper 302 includes a pinion gear 303 that meshes with the gear teeth 242C of the rotating member 242. A plurality of blades disposed inside the damper 302 are attached to the rotation center shaft 304 of the pinion gear 303 via a one-way clutch. When 304 rotates in the R direction in FIG. 27, each blade rotates in the viscous fluid filled in the damper 302 via the connected one-way clutch. For this reason, the rotation member 242 rotates in the P direction at a low speed by the resistance force of the viscous fluid. On the other hand, when the rotation member 242 rotates in the Q direction opposite to the P direction and the pinion gear 303 and the central shaft 304 rotate in the S direction, the rotation in this direction is caused by the cutting action of the one-way clutch. Is not transmitted to the blade. For this reason, the rotation member 242 can rotate at high speed in the Q direction.

  Of the both surfaces in the thickness direction of the rotating member 242, the surface opposite to the surface on which the above-mentioned contacted portion 242B is provided is shown in FIG. A roller 351 that is a protrusion is attached, and this roller 351 is rotatable.

  In the composite device 233 configured as described above, when a lateral tensile force acts on the second portion 236C of the locking wire 236 shown in FIG. 27, the link member 243 is twisted about the shaft 242A. The roller rotates in the Q direction against the spring 301, and the rotation member 242 is in contact with the side surface 242D (see FIG. 28) of the contacted portion 242B of the rotation member 242 by this rotation. Due to the pressing force from 307, the torsion coil spring 300 is rotated about the shaft 242A in the Q direction in FIG. As a result, the pinion gear 303 and the center shaft 304 of the damper 302 rotate in the S direction. As described above, the rotation in the S direction is not transmitted to the blades of the damper 302 due to the cutting action of the one-way clutch. The moving member 242 and the link member 243 rotate at high speed in the Q direction.

  Further, when the tensile force acting on the second portion 236C of the locking wire 236 is reduced or disappears, the link member 243 is moved in the P direction about the shaft 242A by the biasing force accumulated in the torsion coil spring 301. The rotating member 242 is also rotated in the P direction around the shaft 242A by the biasing force accumulated in the torsion coil spring 300. At this time, the pinion gear 303 and the central shaft 304 of the damper 302 rotate in the R direction, and the rotation in the R direction is transmitted to each blade of the damper 302 by the connection action of the one-way clutch. The return rotation of the rotation member 242 in the P direction is performed at a low speed.

  However, the link member 243 at this time is separated from the side surface 242D of the contacted portion 242B of the rotating member 242, in other words, separated from the rotating member 242, so that the accumulated pressure of the torsion coil spring 301 is increased. Since the urging force causes the shaft 242A to pivot around the shaft 242A, the link member 243 pivots and returns to the P direction quickly.

  As can be seen from the above description, the damper 302 provided in the composite device 233 constitutes a delay device 299 for delaying the return of the rotating member 242 to the old position. The moving member 242 is an operating member of the delay device 299 and is a first operating member in this embodiment. Further, the link member 43 is a second operating member in this embodiment. Further, the torsion coil spring 300 and the torsion coil spring 301 serve as urging means for urging and returning the rotating member 242 and the link member 243 to the old positions.

  Further, in this embodiment, a roller 307 is provided on a surface of the link member 243 facing the rotating member 242 among both surfaces in the thickness direction, and the roller 307 is a contacted portion 242B of the rotating member 242. The roller 307 is a contact portion provided on the link member 243 and the contacted portion 242B is provided on the rotation member 242 so that the rotation member 242 is rotated in contact with the side surface 242D. This is the contacted portion.

  Also in this embodiment, since the contact portion is a rotatable roller 307, the rotating member 242 is connected to the link member 243 via the roller 307 and the contacted portion 242B. When the rotation member 242 rotates in the Q direction, the roller 307 is in contact with the contacted portion 242B while rotating with respect to the rotation member 242, and therefore, the link member 243 to the rotation member 242 is contacted. The rotational power can be transmitted smoothly with reduced frictional force.

  Further, in this embodiment, as shown in FIG. 26, the auxiliary member 310A has the link member 243 centered on the shaft 242A toward the locking wire 236, in other words, the link member 243 is connected to the shaft 242A. A pressing means 352 for elastically pressing in the Q direction in FIG. 27 is provided at the center. For this reason, the second portion 236C of the locking wire 236 at the normal time is provided with a bending portion 236D shown in FIGS.

  FIG. 30 is a cross-sectional plan view of FIG. 29 showing the portion of the pressing means 352 shown by a two-dot chain line in FIG. 29 as a solid line, and the pressing means 352 according to this embodiment is formed by a leaf spring. Yes.

  Next, the automatic closing device 232 shown in FIG. 26 will be described. This automatic closing device 232 has a similar structure with basically the same members as the automatic closing device 32 of the embodiment described in FIG.

  That is, the automatic closing device 232 shown in FIG. 26 includes a plate-like slide member 320, and a spring 321 wound around the outer periphery of the slide member 320 in order to apply a forward force to the slide member 320. An actuating member 322 attached to the front end of the slide member 320, a solenoid 326, a spring 328 that imparts an elastic force in the protruding direction to the plunger 327 of the solenoid 326, and one of the sliding type at the tip of the plunger 327 An L-shaped bent lever member 329 connected by a connecting portion 329B and rotatable about a central axis 329A, and the other end of the bent lever member 329 serving as a trigger lever member are rotatable. The attached roller 330, the connecting member 340 attached to the tip of the plunger 327, and the bending lever member 3 It is configured to include a spring 331, 332 for applying a turning force to the T direction around the center axis 329A to 9.

  A concave portion 320B is formed in the portion of the slide member 320 facing the roller 330, and a portion of the concave portion 320B on the retreating side of the slide member 320 is an inclined surface 320C. As shown, the springs 328, 331, and 332 are fitted in the recess 120B by the spring force. By this fitting, the advance of the slide member 320 by the spring 321 is stopped. Thus, the position of the front end of the slide member 320 when the forward movement is stopped by the roller 330 fitted in the recess 320B is the U position among the three positions U, V, and W shown in FIG.

  As shown in FIG. 26, the automatic closing device 232 is provided with a micro switch 335 that is an electric switch, and the micro switch 335 includes an actuator 336. In addition, a dog member 337 is attached to the slide member 320 at a portion opposite to the concave portion 320 </ b> B, and the actuator 336 is in contact with the dog member 337.

  One end of the first manual wire 312 is connected to the connecting member 340 attached to the tip of the plunger 327 of the solenoid 326, and the first manual wire 312 is the same as that in the embodiment shown in FIG. Since it corresponds to the second control wire 112, the first manual wire 312 extends to the operating device 30 shown in FIG. 25, and the other end of the first manual wire 312 is The manual operation member such as a lever member disposed in the operation device 30 is connected.

  The above-described structure is that the automatic closing device 232 of this embodiment is configured in the same manner by basically the same members as the automatic closing device 32 of the above-described embodiment described in FIG.

  In the automatic closing device 232 of this embodiment, one end portion of the second manual wire 313 is connected to the connection portion 338B of the connection member 338 provided on the slide member 320, and this second manual use device 338 is connected. Since the wire 313 corresponds to the third control wire 113 in the embodiment shown in FIG. 21, the second manual wire 313 also extends to the operating device 30 shown in FIG. The other end of the second manual wire 313 is connected to a manual operation member such as a lever member arranged in the operation device 30.

  In this embodiment, as shown in FIG. 26, the slide member 320 has a protrusion 353 on the rear side in the sliding direction of the slide member 320 relative to the roller 351 provided on the rotating member 242. In this embodiment, the protrusion 353 is formed by bending the rear end portion of the connecting member 338 provided on the slide member 320.

  When the shutter device according to this embodiment is used as a management shutter device by operating the “open”, “closed”, and “stop” buttons provided on the operation device 30, the shutter curtain 1 When the obstacle 34 shown in FIG. 25 exists in the closing direction, the closing end of the shutter curtain 1 abuts against the obstacle 34 during the closing movement of the shutter curtain 1.

  As a result, as in the above-described embodiment, the shutter curtain 1 and the locking wire 236 that is the string-like member according to the present embodiment are mechanically coupled by the mechanical coupling device 39, and the lock Since the weight of the portion of the shutter curtain 1 above the curtain sub-portion 71B of the shutter curtain 1, that is, the weight of the curtain main portion 71A, acts on the second portion 236C of the wire 236 for locking. In FIG. 27, a lateral tensile force, in other words, a lateral tension force acts on the two portions 36C. Therefore, when the obstacle 34 comes into contact with the shutter curtain 1, the lock wire 236 becomes a tension force acting member to which the tension force due to the weight of the curtain main portion 71 </ b> A acts. 27, the delay device 299 including the rotary damper 302 of FIG. 27 is connected.

  In addition, when a lateral tension force acts on the second portion 236C of the locking wire 236 in FIG. 27, the end of the second portion 236C is connected to the link member 243 in FIG. After the bending portion 236D provided in the portion 236C disappears, the link member 243 starts to rotate in the Q direction around the shaft 242A while facing the torsion coil spring 301.

  FIG. 31 shows a state in which the link member 243 is rotated in the Q direction about the shaft 242A from the state of FIG. 27. Thus, when the link member 243 is rotated in the Q direction about the shaft 242A, the link Since the actuator 309 of the electrical switch 308 that has been in contact with the member 243 is activated, a signal from the electrical switch 308 is input to the control device 26 of FIG. Thereby, the control device 26 stops energization to the solenoid 24 energized until that time of the switch 13 shown in FIG. 25 for a short time, and electrically turns on the brake means 19 of the switch 13. And when the closing movement of the shutter curtain 1 is performed by rotating the winding shaft 11 of FIG. 25 by energizing the coil 25 of the opening / closing machine 13, the coil 25 is energized for a short time. After stopping the shutter curtain 1 in contact with the obstacle 34 for a short time set by the control device 26 as in the above embodiment, the control device 26 By electrically turning off the brake means 19 by energizing the solenoid 24 and energizing the coil 25, the shutter curtain 1 is moved by reverse rotation of the winding shaft 11. Rolling is increased.

  When the shutter curtain 1 is turned upside down in this way, the shutter curtain 1 moves away from the obstacle 34, so that the tension force acting on the second portion 236C of the lock wire 236 starts to decrease or disappear, like this When the tension force starts to decrease or disappear, the link member 43 in FIG. 27 returns to the direction P in FIG. 27 by the urging force accumulated in the torsion coil spring 301. As a result, the actuator 309 of the electric switch 308 also returns to the original state shown in FIG. 27, and the control device 26 of FIG. The energization to the solenoid 24 of the opening / closing machine 13 is interrupted to turn on the brake means 19 and the energization to the coil 25 is interrupted to stop the reversal of the shutter curtain 1.

  For this reason, also in this embodiment, the shutter curtain 1 is stopped at a position where it is slightly reversed and raised, and thus, an operation such as removal of the obstacle 34 from the entrance 2 shown in FIG. 25 can be performed. become able to. Further, by operating the operation device 30, the shutter curtain 1 can be closed and opened as a shutter curtain of the management shutter device.

  As described above, when a lateral tension force acts on the second portion 36C of the locking wire 36 and the link member 43 rotates in the Q direction in FIG. 27, it is a constituent member of the delay device 299. The rotating member 242 also rotates in the Q direction against the torsion coil spring 300 by the pressing force from the roller 307 that contacts the side surface of the contacted portion 242B of the rotating member 242, but in this Q direction. As can be seen from the above description, since the rotary damper 302 does not function as a constituent member of the delay device 299, the lateral tension acts on the second portion 36C of the locking wire 36, and thus the link The member 43 immediately rotates in the Q direction, and the electric switch 308 can be immediately activated by this rotation.

  In this embodiment, the auxiliary member 310A described above is provided with the stop member 354 shown in FIGS. 27 and 31, and the rotation of the link member 243 in the Q direction is shown in FIG. As described above, when the link member 243 comes into contact with the stop member 354, it stops. For this reason, the stop member 354 is a rotation limit defining member for defining the rotation limit of the link member 243 in the Q direction.

  In this embodiment, the delay device 299 by the rotary damper 102 and the automatic closing device 232 are disposed adjacent to each other as constituting the composite device 233, and the rotating member 242 is rotated to the state shown in FIG. When moved, the roller 351 provided on the rotating member 242 moves toward the protrusion 353 provided on the slide member 320 of the automatic closing device 232, but the link member 243 is defined by the stop member 354. When the rotation limit in the Q direction is reached, the roller 351 does not reach the position of the protrusion 353 as shown in FIG. For this reason, the rotation of the link member 243 in the Q direction does not affect the slide member 320 of the automatic closing device 232.

  That is, even if the rotation member 242 rotates in the Q direction, the slide member 320 does not slide from the position shown in FIG. 26 and maintains this position.

  Further, as described above, the link member 243 accumulates pressure on the torsion coil spring 301 when the tension force acting on the second portion 236C of the lock wire 236 starts to decrease or disappear due to the reversal rise of the shutter curtain 1. When the urging force is returned to the P direction in FIG. 27, the rotating member 242 of the delay device 299 is also rotated and returned in the P direction by the urging force accumulated in the torsion coil spring 300. Is returned at a low speed due to the delay action of the delay device 299 formed by the rotary damper 102. At this time, the roller 307 is separated from the side surface of the contacted portion 242B of the rotating member 242. In other words, since the link member 243 is separated from the rotation member 242, the link member 243 can be quickly returned to the P direction. Can be performed, thus, be restored to the actuator 309 of the electrical switch 308 to the original state shown in FIG. 27 can also be carried out rapidly.

  Also, the electrical switch 308 according to this embodiment is a B-type contact electrical switch, like the electrical switch 108 of the embodiment shown in FIG. It is possible to transmit a signal from the electric switch 308 to the control device 26 more reliably by a slight rotation of the member 242 in the Q direction. For this reason, the control device 26 controls the closed moving shutter curtain. The operation of once stopping 1 for a short time and then reversely raising it can be performed more rapidly after the shutter curtain 1 is brought into contact with the obstacle 34.

  As can be seen from the above description, also in this embodiment, when the shutter device of this embodiment is a management shutter device that opens / closes and stops moving by the operation of the operation device 30, the shutter curtain being closed and moving When 1 abuts against the obstacle 34, this abutment can be detected by the electric switch 308 through the lock wire 236 and the link member 243 which are string-like members. For this reason, by electrically controlling the switch 13 with the control device 26 that receives the signal from the electric switch 308, the brake means 19 of the switch 13 is electrically turned on for only a short time, and the shutter curtain 1 is turned on. The shutter curtain 1 can be turned upside down by temporarily stopping and turning off the brake means 19 and energizing the coil 25.

  Further, when the tension force acting on the second portion 236C of the lock wire 236 is reduced or disappeared due to the reverse movement of the shutter curtain 1, the low-speed return rotation in the P direction of the rotating member 242 is affected. Therefore, the link member 243 can be quickly returned and rotated, so that the electric switch 308 can be quickly returned to the original state, and the shutter curtain 1 can be reversed by this early return action. The control of stopping the shutter curtain 1 immediately after the start of ascent can be performed by the control device 26 to which a signal from the electric switch 308 is input.

  When the tension applied to the second portion 236C of the lock wire 236 is reduced or disappeared by the reversal and raising of the shutter curtain 1, the control device 26 to which a signal from the electric switch 308 is input causes the shutter curtain Also in this embodiment, the control performed for 1 is not limited to the control for stopping the reversal and raising of the shutter curtain 1 as described above.

  That is, also in this embodiment, when the tension force acting on the second portion 236C of the lock wire 236 is reduced or disappeared by the reverse raising of the shutter curtain 1, the signal from the electric switch 308 is input. The control performed on the shutter curtain 1 by the device 26 may be control for causing the shutter curtain 1 that has been reversed and lifted to stop the reversal and then restart the closing movement. Alternatively, the shutter curtain 1 that is in contact with the obstacle 34 may be controlled. In the case of stopping without reversing and raising, control for releasing the stop and restarting the closing movement may be performed.

  In a building where the shutter device according to this embodiment is installed, when a disaster such as a fire occurs when the shutter curtain 1 is fully open and stopped, a signal from a sensor that detects this disaster is input. Since the solenoid 326 of the automatic closing device 232 in FIG. 26 is energized and excited by a control device that does not (this control device may be used in this embodiment or the control device 26 in FIG. 25), The plunger 327 of the solenoid 326 is retracted against the spring force of the spring 328, and the bending lever member 329 is opposed to the spring force of the springs 331 and 332, and the T direction in FIG. It rotates in the opposite direction. The state at this time is shown in FIG. At this time, since the roller 330 of the bending lever member 329 escapes from the concave portion 320B of the slide member 320, the slide member 320 is advanced by the spring force of the spring 321, and this advance is caused by the front end of the connecting member 338 of the automatic closing device 232. It stops by contacting the rising portion 310B of the machine casing 310. The position of the front end of the slide member 120 at this time is the W position that is the foremost position among the three positions U, V, and W shown in FIG. 26, as shown in FIG.

  Note that a signal from a sensor that detects the occurrence of a disaster such as a fire is sent to the control device 26 in FIG. 25, and the control device 26 that has received this signal may subsequently operate the electric switch 308 in FIG. The signal sent from the electrical switch 308 is invalidated.

  When the slide member 320 advances to the W position in FIG. 32, the actuator 336 of the micro switch 335 is disengaged from the dog member 337 when the dog member 337 attached to the slide member 320 moves to the position in FIG. In response to a signal from the microswitch 335, the control device stops energizing the solenoid 326. Accordingly, the plunger 327 projects and moves from the solenoid 326 by the spring force of the spring 328, and the bending lever member 329 rotates in the T direction in FIG. 26 about the central shaft 329A by the spring force of the springs 331 and 332. Since the slide member 320 at this time has advanced to the movement limit where the front end of the slide member 320 reaches the W position, the roller 330 of the bending lever member 329 has a slide member 320 as shown in FIG. This corresponds to the above-described inclined surface 320C. For this reason, the protruding movement of the plunger 327 and the rotation of the bending lever member 329 about the central axis 329A in the T direction stop halfway.

  At this time, as shown in FIG. 33, the protrusion 353 provided on the slide member 320 is at the position of the roller 351 provided as a protrusion on the rotating member 242 of the delay device 299 or at this position. It has reached a close position. The state at this time is also shown in FIG.

  When the slide member 320 of the automatic closing device 232 moves forward as described above, also in this embodiment, the operating member 322 provided at the front end of the slide member 320 is moved via the operated member 123 shown in FIG. In order to press the first portion 31A of the lever member 31 of the opening / closing machine 13 in the direction A in FIG. 3, the brake shaft 21 and the brake drum 22 of the brake means 19 of the opening / closing machine 13 are in the same direction as the A direction. The brake means 19 that slides in the direction and has been turned on until then is mechanically turned off. For this reason, the shutter curtain 1 that has been fully opened moves and closes downward while rotating the winding shaft 11 due to the weight of the seat plate 1B and the like below the winding shaft 11. When the curtain 1 is fully closed, a disaster prevention zone by the shutter curtain 1 is formed.

  In addition, when a person discovers that a disaster such as a fire has occurred, this person is placed in the operating device 30 shown in FIG. 25 and is attached to the end of the first manual wire 312 in FIG. The first manual wire 312 is pulled by a manual operation member such as a connected lever member. As a result, the roller 330 of the bending lever member 329 escapes from the concave portion 320B of the slide member 320 as in the case where the second control wire 112 of the embodiment described above with reference to FIG. The slide member 320 moves forward by the spring force of the spring 321.

  When the shutter curtain 1 reaches the fully closed position and a disaster such as a fire is resolved, the shutter curtain 1 is disposed on the operating device 30 shown in FIG. 25 and is connected to the end of the second manual wire 313 described above. The second manual wire 313 is pulled by a manual operation member such as a lever member. As a result, the slide member 320 moves backward against the spring force of the spring 321 as in the case where the third control wire 113 of the embodiment described above with reference to FIG. For this reason, the slide member 320 returns from the position shown in FIG. 33 to the initial position where the front end is the U position in FIG. Further, when the slide member 320 returns to this initial position, the bending lever member 329 is rotated in the T direction in FIG. 26 by the spring force of the springs 331 and 332 about the central axis 329A. As shown in FIG. 26, the roller 330 is fitted into the recess 320B of the slide member 320, and the backward movement of the slide member 320 stops when the front end of the slide member 320 reaches the U position. Thereby, the automatic closing device 232 returns to the initial state before the occurrence of a disaster such as a fire.

  When the slide member 320 returns to the initial position, the brake shaft 21 and the brake drum 22 of the brake means 19 of the opening / closing machine 13 are moved in the direction opposite to the A ′ direction by the spring 23 described above with reference to FIG. 19 is mechanically turned back on. Thereafter, by operating the above-mentioned “open” button provided in the operating device 30, the shutter curtain 1 opens and moves to the fully open position as described above.

  In this embodiment as well, the solenoid 326 of the automatic closing device 232 is energized or excited by the control device that receives a signal from a sensor that detects a disaster such as a fire, or connected to the end of the first manual wire 312. The first manual wire 312 is pulled by a manual operation member such as a lever member, and thereby the brake means 19 of the switch 13 is turned off, and the shutter curtain 1 is closed and moved downward from the fully open position. The time is when the shutter device of this embodiment is a shutter device for disaster prevention. At this time, the brake means 19 of the switch 13 shown in FIG. 3 is a brake means that is mechanically turned on and off by the slide of the slide member 320 of the automatic closing device 232 as is apparent from the above description. ing.

  Further, when the shutter device according to this embodiment is a disaster prevention shutter device and the shutter curtain 1 is closed and moved downward from the fully open position, in other words, the automatic closing device 232 is shown in FIG. When the shutter curtain 1 is closed and moved downward from the fully open position and the obstacle 34 shown in FIG. 1 exists below the shutter curtain 1 in the closing movement direction. In the middle of the closing movement of the shutter curtain 1, the closing end of the shutter curtain 1 comes into contact with the obstacle 34.

  Accordingly, even when the shutter device of this embodiment is a disaster prevention shutter device, the shutter curtain 1 and the lock are locked as in the case where the shutter device according to this embodiment is the aforementioned management shutter device. The mechanical wire 236 is mechanically coupled to the mechanical coupling device 39, whereby a tension force due to the weight of the curtain main portion 71A of the shutter curtain 1 acts on the second portion 236C of the locking wire 236. become.

  For this reason, the link member 243 rotates in the Q direction in FIG. 27, and the rotation member 242 in which the roller 307 of the link member 243 contacts the side surface of the contacted portion 242B also rotates in the Q direction. When the link member 43 rotates in the Q direction, the actuator 309 of the electric switch 308 shown in FIG. 27 operates. At this time, as described above, the signal input from the electric switch 308 to the control device 26 is invalid. Therefore, the control device 26 does not cause the opening / closing machine 13 to perform control to reversely raise the shutter curtain 1.

  Further, when the link member 243 is rotated in the Q direction by the tension applied to the second portion 236C of the locking wire 236, the rotating member 242 is also rotated in the Q direction. By the contact between the roller 351 provided and the protrusion 353 provided on the slide member 320, the slide member 320 slides backward against the spring 321. That is, in this embodiment, the roller 351 provided on the rotating member 242 constituting the delay device 299 and the projection 353 provided on the slide member 320 constituting the automatic closing device 232 are directly provided. By abutting, the slide member 320 slides backward against the spring 321. As a result, the front end of the slide member 120 moves backward to the V position, which is an intermediate position between the W position and the U position in FIG. The state at this time is shown in FIGS. Although the slide member 320 at this time is retracted, the roller 330 of the bending lever member 329 is not fitted in the concave portion 320B of the slide member 320 as shown in FIG. As shown in FIG. 36, the limit of rotation of the link member 243 in the Q direction is defined by the stop member 354 when the link member 243 abuts on the stop member 354 described above.

  Note that the rotation of the rotation member 242 is rotation about the shaft 242A. For this reason, the roller 351 provided as a protrusion on the rotation member 242 is a protrusion 353 provided on the slide member 320. The roller 351 moves up and down with respect to the projection 353 when the slide member 320 is caused to slide backward due to the contact with the roller 351. However, since the roller 351 is rotatable, the roller 351 is moved relative to the projection 353. By rotating, the slide member 320 slides backward smoothly.

  Further, as described above, when the position of the front end of the slide member 320 is retracted from the W position to the V position, the operating member 322 of the slide member 320 causes the first portion 31A of the lever member 31 of FIG. The load that has been pressed in the A direction is released. For this reason, the brake means 19 of the switch 13 is mechanically switched from off to on. When the brake means 19 is turned on, the drive shaft 14 of the opening / closing machine 13 cannot rotate, so that the winding shaft 11 to which the upper end of the shutter curtain 1 is coupled cannot also rotate. Therefore, the shutter curtain 1 that is in contact with the obstacle 34 closes and stops moving at the contact position.

  Thus, after the shutter curtain 1 in the closing movement comes into contact with the obstacle 34 and the brake means 19 of the switch 13 is mechanically turned on to stop the closing movement of the shutter curtain 1, the obstacle 34 is removed. Then, the mechanical coupling state between the shutter curtain 1 and the lock wire 236 by the mechanical coupling device 39 is released. As a result, the tension of the second portion 236C of the lock wire 236 disappears, and the link member 243 and the rotating member 242 to which the return force by the torsion coil springs 301 and 300 in FIG. 27, and the slide member 320 of the automatic closing device 232 is moved by the spring 321 from the V position shown in FIG. 35 to the position shown in FIG. Move forward to the indicated W position. For this reason, the brake means 19 of the opening / closing machine 13 is mechanically switched again from on to off, and the shutter curtain 1 resumes its closed movement.

  In addition, when the rotating member 242 rotates in the direction P in FIG. 27, the pinion gear 303 of the rotary damper 302 rotates in the direction R in FIG. 27, and the resistance force caused by the viscous fluid is applied to the damper 302 in the direction R. Arise. For this reason, the position of the front end of the slide member 320 shifts from the V position shown in FIG. 35 to the W position shown in FIG. 26, and the brake means 19 of the switch 13 is mechanically switched from on to off by this shift. This is not done instantaneously due to the delay action of the damper 302. Therefore, the shutter curtain 1 closing and resuming the movement by removing the obstacle 34 starts with a time delay from the removal of the obstacle 34, and therefore, the removal operation of the obstacle 34 has a time margin. It can be carried out.

  As can be seen from the above description, the damper 302 and the rotating member 242 constitute a delay device 299 for delaying the restart when the shutter curtain 1 is closed and restarted after the obstacle 34 is removed. It has become.

  This delay device may employ mechanical means including a mainspring timer that can set the delay time more accurately without being affected by the environmental temperature, for example, instead of the damper 302.

  Then, after the shutter curtain 1 that has resumed the closing movement is fully closed, the second manual wire 313 is pulled by the above-described manual operation member such as a lever member disposed in the operation device 30, thereby automatically closing. Since the slide member 320 of the device 232 performs a return movement in which the position of the front end returns to the U position in FIG. 26, the entire automatic closing device 32 returns to the initial state in FIG.

  As described above, also in this embodiment, the long hole 306 is formed in the link member 243 of FIG. 27, and the connecting portion 243A of the second portion 236C of the locking wire 236 and the link member 243 is formed in the long hole 306. The pin 305 is inserted, and the elongated hole 306 has a V shape or a substantially V shape in which the first portion 306A and the second portion 306B are connected with a bending angle. It is bigger than the degree. Then, when the rotating shutter 242 and the link member 243 are in the state shown in FIG. 36 due to the shutter curtain 1 being moved in contact with the obstacle 34, as seen from the back side of the composite device 233, as shown in FIG. As shown in FIG. 37 showing a front sectional view, the extension portion 301B of the torsion coil spring 301 for applying the turning force in the direction P of FIG. 27 to the link member 243 is provided between the link member 243 and the locking wire 236. Since it is locked to the pin 305 that is a constituent member of the connecting portion 243A with the second portion 236C, the connecting portion 243A is connected to the first portion 306A and the second portion 306A of the elongated hole 306, as in FIG. Of the portion 306B, it remains at the position of the first portion 306A.

  Also in this embodiment, for the same reason as in the above embodiment, a large lateral tensile amount may occur in the second portion 236C of the locking wire 236.

  When a large lateral tensile amount is generated in the second portion 236C of the locking wire 236, the link member 243 and the rotating member 242 according to this embodiment stop the rotation of the link member 243 in the Q direction in FIG. Since it is restricted by the member 354, it does not rotate in the Q direction from the state of FIG. For this reason, the connecting portion 243A is a second portion from the first portion 306A of the elongated hole 306 that is a guide portion that guides the movement of the connecting portion 243A while resisting the elastic force of the torsion coil spring 301 that is an elastic member. Transition to 306B, the connecting portion 243A reaches the end of the second portion 306B, as indicated by the two-dot chain line in FIG.

  Also in this embodiment, the link member 243 is an intermediate member disposed between the locking wire 236 and the automatic closing device 232, which is a tension acting B member, as can be understood from the above description. When the connecting portion 243A reaches the end of the second portion 306B of the long hole 306 formed as a guide portion in the intermediate member, the large tensile amount is absorbed by the long hole 306. For this reason, also in this embodiment, when a large amount of tension is generated in the second portion 236C of the locking wire 236, the connecting portion 243A is movable with respect to the link member 243. For this reason, the locking wire 236 It is possible to prevent a large tension force from acting on the second portion 236C.

  In addition, as shown in FIG. 37, the portion where the connecting portion 243A moves when a large tensile amount is generated in the second portion 236C of the locking wire 236 is the horizontal direction or the substantially horizontal portion of the long hole 306. The second portion 306B extending in the direction, and the direction in which the second portion 306B extends is the same as or substantially the same as the direction of the tension force acting on the second portion 236C of the locking wire 236. Due to the large amount of tension, the connecting portion 243A can smoothly reach the end of the second portion 306B.

  Further, in the state shown in FIG. 37 before a large amount of tension acts on the second portion 236C of the lock wire 236, the elastic force of the extension portion 301B of the torsion coil spring 301 includes the moving direction of the connecting portion 243A. Since there is a component in the direction opposite to the extending direction of the long hole 306, the movement of the connecting portion 243A along the long hole 306 is prevented by the torsion coil spring 301. The position of the connecting portion 243A can be stopped at the position shown in FIGS.

  Further, in the entire range in which the connecting portion 243A is guided to the long hole 306 and moves to the position indicated by the two-dot chain line in FIG. 37, the extending portion 301B of the torsion coil spring 301 is always connected to the connecting portion 43A. In order to maintain the contact state, when the connecting portion 243A moves while being guided by the elongated hole 306, the torsion coil spring 301 has an elastic return for returning the connecting portion 243A to the original position before the movement. Accordingly, when the shutter curtain 1 is opened and moved and the above-described large tensile amount disappears, the connecting portion 243A is long due to the elastic restoring force accumulated in the torsion coil spring 301. The hole 306 will naturally return to its original position in the first portion 306A.

  Further, the torsion coil spring 301 is an elastic member for applying a rotational force in the direction P in FIG. 27 to the link member 243 that is an intermediate member disposed between the locking wire 236 and the automatic closing device 232. Therefore, the elastic force having a component on the side opposite to the extending direction of the long hole 306 is formed in the connecting portion 243A by the combined use of the elastic member. It is possible to realize the above-described operation and to return the connecting portion 243A to the original position before the movement.

  Further, in this embodiment, the pressing member 352 in FIG. 30 applies a pressing force in the Q direction in FIG. 27 to the link member 243, so that the second portion 236C of the locking wire 236 in the normal state is shown in FIG. 27 and FIG. 29, the bending portion 236D shown in the above embodiment is provided, so that the first control wire 111 described in the above embodiment is provided with the bending portion 111A. There is no possibility that the second portion 236C bend due to aging or the like that occurs when the second portion 236C is tensioned. For this reason, when the shutter curtain 1 in the closing movement comes into contact with the obstacle 34, the slide member 320 that has reached the advance limit of the automatic closing device 232 moves backward by the tensile action of the second portion 236 </ b> C of the locking wire 236. At this time, there is no possibility that the amount of reverse movement is reduced by the amount of bending, and as a result, the brake means 19 of the switch 13 can be switched from OFF to ON more reliably.
