Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes means for detecting the state of the opening / closing means, such as an obstacle detection means for detecting an obstacle during the opening / closing operation by a seat plate switch at the closing tip provided on the opening / closing means such as a shutter curtain. The present invention relates to an opening / closing device, and more particularly, to an opening / closing device in which the routing means of wiring means for transmitting a detection signal detected by a detection means to a place other than the opening / closing means is improved.
[0002]
[Prior art]
The opening / closing device closes the opening by moving an opening / closing member such as a shutter curtain installed in the opening of a structure housing including a building such as a house, building, factory, warehouse, or garage. The opening / closing device gradually draws and lowers the shutter curtain as an opening / closing member from the upper part of the opening to close the entire opening. A seat plate switch is provided on the closing tip side of the opening / closing member. When this seat plate switch contacts any obstacle during the opening / closing operation, an obstacle detection signal is output from the seat plate switch. The control device that has received the obstacle detection signal stops the opening / closing operation of the opening / closing member itself in order to avoid the obstacle being caught, and controls the operation of the opening / closing member to perform the avoiding operation.
[0003]
Conventionally proposed devices that transmit obstacle detection signals detected by the seat switch to the control device include wireless and wired methods. In the case of the wireless system, a battery for driving the signal generator is required on the seat plate switch side, and its maintenance is difficult. On the other hand, in the case of the wired system, it is only necessary to electrically connect the seat plate switch and the control device using a lead wire or the like. It is advantageous.
[0004]
In the case of the wired system, the distance from the seat plate switch to the control device differs greatly between when the open / close member is in the open state and when it is in the closed state. It is necessary to make the length of the lead wire longer or shorter according to the distance between the seat plate switch and the control device so that the length of the lead wire does not bend or come into contact with other members. There is. Therefore, conventionally, the lead wire is directly wound around the take-up reel biased in the winding direction by the spring so that the length of the lead wire can be appropriately adjusted according to the opening / closing operation of the shutter curtain. Things have been proposed. Since the lead wire is directly wound around the reel, the winding diameter of the reel itself may be increased depending on the length and thickness of the lead wire. Therefore, it may be difficult to install the entire winding mechanism in the case that houses the shutter curtain. Therefore, Patent Document 1 discloses a configuration in which a lead wire is accommodated in a rail.
[Patent Document 1]
Japanese Utility Model Publication No. 2-134299
[0005]
[Problems to be solved by the invention]
In Patent Document 1, a static pulley and a moving pulley are interposed in an intermediate portion of a lead wire so that the moving pulley is accommodated in the rail and moved up and down in the rail. However, since the lead wire routed from the seat switch as an obstacle detection unit to the static pulley is disposed between the shutter curtain and the rail member, the one described in Patent Document 1 Since the shutter curtain and the rail member come into contact with each other at the time of ascent and descent, the lead wire may be damaged or the wire may be severely disconnected, which is not preferable.
[0006]
An object of the present invention is to provide a switchgear that can be wired without causing wiring means such as a lead wire to come into contact with or damage to other members.
[0007]
[Means for Solving the Problems]
The opening / closing device according to claim 1 detects opening / closing means operating to open / close the opening, guide means for guiding the opening / closing operation of the opening / closing means, and movement of the opening / closing means to detect the state of the opening / closing means. Detection means for outputting the detection signal, control means for recognizing the state of the opening / closing means based on the detection signal, wiring means for transmitting the detection signal detected by the detection means to the control means, The wiring means heading from the detection means to the control means is once bent using a fixed guiding means provided in the vicinity of the guide means so that a guide groove for guiding the wiring means is substantially parallel to the opening surface. The wiring means is further bent using a movable guiding means so as not to bend and urged in a predetermined direction, and the distance between the detection means and the control means is determined according to the open / close state of the open / close means. The movable guiding means moves along the predetermined direction in response to the change in the position, and the wiring means is mounted on the opening / closing means separated from the guide means by a predetermined distance so as not to be detached from the fixed guiding means. And a wiring routing means configured as described above.
[0008]
The opening / closing means is composed of an opening / closing member such as a shutter curtain that opens and closes an entrance / exit, a window, or an internal passage / space in a structure such as a building, house, factory, warehouse, etc. . When the opening / closing means is a shutter curtain, for example, the shutter curtain is housed in an upper portion of an opening such as a building, and the shutter curtain descends along the guide means via a lintel or the like to close the opening. In addition to this, there is a type in which the opening / closing means is housed in the side portion of the opening and opened and closed by a horizontal pulling method, or is housed in the lower part of the opening and moved in an ascending manner. The detection means is provided at the tip of the opening / closing means and moves together with the opening / closing means. For example, the obstacle detection is to detect the presence of an obstacle on or near the movement path during the opening / closing movement of the opening / closing member. It is a means (for example, a seat plate switch), an opening / closing position of an opening / closing member, a heat detector for detecting heat of the opening / closing member, and a lock / unlock state of the opening / closing member is detected. Or something to do. Therefore, the detection signal detected by the detection means is transmitted to the recognition means provided separately from the opening / closing means via the wiring means. The recognizing unit recognizes the state of the opening / closing unit in accordance with the detection signal, and performs processing corresponding to the state. For example, when the detection means is an obstacle detection means and the detection signal is taken into the recognition means, the recognition means performs an obstacle avoidance operation or the like. The recognizing unit only recognizes the detection signal from the obstacle detecting unit, and transmits the recognition result to another control device or the like so that the obstacle avoiding operation or the like is executed by the control device. It may be a thing.
[0009]
At this time, the wiring means for transmitting the detection signal from the detection means to the recognition means is bent so as not to be bent by the fixed guiding means and the movable guiding means so as not to pass between the opening / closing means and the guide means. Be circulated. The fixed guiding means and the movable guiding means are configured to guide or guide the wiring means by rotation, such as a roller or a pulley, or to guide and guide the wiring means by a member that does not rotate but has good slippage. It has a guide groove for guiding. The fixed guiding means is provided in the vicinity of the guide means so that the guide groove is substantially parallel to the opening surface. The movable guiding means further bends the wiring means bent by the fixed guiding means and biases it in a predetermined direction. Therefore, even when the distance between the detection means and the control means changes due to the opening / closing operation of the opening / closing means, the length of the wiring means from the fixed guidance means to the detection means by moving the movable guidance means in a predetermined direction. Is appropriately adjusted so that the wiring means does not bend as a whole. The movable guiding means may move inside the guide means, or may be provided along the guide rail and move inside the structure that is protected and covered by a cover or the like. Moreover, you may make it move on the special rail provided in the opening part along the periphery. When the movable guiding means is provided inside or along the guide means, the movable guiding means can be biased downward by a load such as a weight. Further, in the case where it is not possible to urge by a weight or the like, it can be dealt with by adding an elastic means such as a spring for urging the movable guiding means in a predetermined direction.
[0010]
Since the guide groove of the fixed guiding means is provided in the vicinity of the guide means so as to be substantially parallel to the opening surface, wiring is performed during the opening / closing operation of the opening / closing means depending on the vicinity of the opening / closing means. There is a possibility that the means may come off the fixed guiding means. For example, when the crossing angle formed by the wiring means and the extension line of the guide groove of the fixed guide means is almost 0 °, that is, when the wiring means is positioned on the extension line of the guide groove of the fixed guide means, the wiring means is fixed. Although there is little possibility of coming off from the guide groove of the guide means, the greater the crossing angle, the higher the possibility that the wiring means will come off the guide groove of the fixed guide means. Therefore, in the present invention, the crossing angle is prevented from becoming so large by mounting the wiring means on the opening / closing means separated from the guide means by a predetermined distance so as not to be detached from the fixed guiding means.
[0011]
According to a second aspect of the present invention, in the switchgear according to the first aspect, the wiring routing means is an angle formed between the wiring means heading from the detection means toward the fixed guiding means and an extension line of the guide groove of the fixed guiding means. However, the wiring means can be mounted on the opening / closing means that is separated by a predetermined distance from the guide means so that the wiring means does not come off from the fixed guiding means. This means that when the wiring means is mounted on the opening / closing means separated from the guide means by a predetermined distance so as not to be detached from the fixed guiding means, the crossing angle is set to an angle or less so that the wiring means is not detached from the fixed guiding means. It is a thing. The angle at which the wiring means does not come off from the fixed guiding means depends on the structure of the fixed guiding means. In the case of a pulley, the angle is determined based on the shape of the groove and the wiring means.
[0012]
According to a third aspect of the present invention, the opening / closing device according to the first or second aspect is configured such that the movable guiding means is arranged in the guide means or adjacent to the guide means. This relates to the arrangement place of the wiring routing means, and the movable guiding means is arranged in the guide means provided on both sides of the shutter curtain or the like so as to be adjacent thereto. Arranging the wiring routing means in the guide means is effective when a sufficient installation space cannot be secured on the storage side of the opening / closing means. Further, if the wiring routing means is arranged adjacent to the guide means, there is an advantage that a new storage member for storing the movable guiding means need only be installed in the guide means.
[0013]

In addition to stopping the lowering operation, the shutter curtain 2 may be controlled to move up so that the detection signal is not output, and other operations, for example, the operation of decreasing the lowering speed without stopping the operation. You may control to perform.
[0017]
FIG. 2 is a perspective view showing a part of the obstacle detection device and the wiring means shown in FIG. FIG. 3 is a front view of FIG. 2 viewed from a direction perpendicular to the opening surface. FIG. 4 is a diagram showing a wiring state around the seat plate of FIG. 2, and is a diagram showing a part of the seat plate portion removed. FIG. 5 is a side view of FIG. 4 viewed from the right side. The obstacle detection device basically includes a seat plate switch 10 serving as an obstacle detection means, cords 11a to 11c serving as wiring means, a fixed pulley 18a serving as a fixed guiding means, a movable pulley 18b serving as a movable guiding means, and weight means. It is comprised from the wiring management means which consists of the flat bar 19 used.
[0018]
The seat plate switch 10 is provided in a lower part on the closed front end side of the shutter curtain 2. Since the seat plate switch 10 is a known one, a detailed description thereof will be omitted here, but basically, an upper seat plate 100, and a lower seat plate 101 held so as to be vertically movable with respect to the upper seat plate 100, The pressing portion 102 attached to the lower seat plate 101 and the rotating portion 103 rotate as the lower seat plate 101 (that is, the pressing portion 102) moves up and down, whereby the micro switch 105 is turned on / off. Has been. That is, the seat plate switch 10 outputs a detection signal indicating that the micro switch 105 is turned on and the obstacle is detected when the lower seat plate 101 contacts the obstacle and moves upward. . The cords 11 a to 11 c are wiring means for transmitting a detection signal from the seat plate switch 10 to the control device 8. The cord 11a is wired so as to form a predetermined angle with the direction along the rising and lowering of the seat plate switch 10. That is, the guide rails 3 and 4 are provided so as to form a predetermined angle (a predetermined angle with respect to the floor 21).
[0019]
The connector 11 d provided at the tip of the cord 11 a is housed in the wiring cover 40 via the rubber bush 34. At this time, the cord 11 a is fixed in contact with the rubber bush 34 that is ball-tied in the wiring cover 40 and inserted into the notch 40 c of the wiring cover 40. The connector 11 d is connected in the wiring cover 40 to the connector of the cord 106 connected to the microswitch 105. The cord 106 connected to the microswitch 105 is bent from the right end of the upper seat plate 100 in FIG. 4 and wired to the upper portion of the upper seat plate 100, and is connected to the connector 11d at the upper portion of the upper seat plate 100. The wiring cover 40 is fixed integrally to the slat curtain 2 by fixing tools 40a and 40b such as bolts, screws and rivets. A touch plate 41 is fixed to the slat curtain 2 as a single unit by a fixing tool such as a bolt, a screw, or a rivet at a position adjacent to the wiring cover 40 and facing an emergency switch (not shown). . The wiring cover 40 has notches 40c and 40d on the left and right, but the rubber bush 34 is inserted into the notch 40c when attached to the right front side as shown in FIG. 4, and the notch 40d has the opposite. The rubber bush 34 is inserted when attached to the left front side. By appropriately adjusting the positions of the notches 40c and 40d, the angle of the cord 11a with respect to the guide rails 3 and 4 (or the angle with respect to the floor surface 21) can be adjusted.
[0020]
The fixed pulley 18 a converts the cord 11 a into a cord 11 b in a direction parallel to the longitudinal direction of the guide rail 3. The movable pulley 18b changes the direction of the cord 11b to a cord 11c parallel to the longitudinal direction of the guide rail 3 and opposite to the cord 11b, bends, and is introduced into the control device 8 via the cord fixing plate 20. To do. The flat bar 19 supplies a constant tensile force to the cords 11a to 11c.
The movable pulley 18b and the flat bar 19 are connected (linked) as a unit by a fixing tool such as a screw or a rivet. Further, in the drawing, the movable pulley 18b is provided on the upper side of the flat bar 19 so as to be separable. However, the present invention is not limited to this, and the movable pulley 18b may be provided integrally in the flat bar 19. Thus, by installing the movable pulley 18b, the flat bar 19 and the like in the guide rail 3, it is not necessary to provide a separate installation location. In this embodiment, since the movable pulley 18b and the flat bar 19 are accommodated in the guide rail 3 and moved up and down there, it is not necessary to separately provide an installation location. Further, since the cord 11a is connected to the seat plate switch 10 at a predetermined angle with respect to the guide rail 3, there is no risk of contact interference between the shutter curtain 2 and the guide rail 3, and a stable obstacle Detection can be performed.
[0021]
FIG. 6 is a diagram showing details of the wiring routing means including the cord, fixed pulley, movable pulley and flat bar of FIG. FIG. 7 is a perspective view showing a part of FIG.
The base 30 is attached to the lintel unit 9 by a fixture such as a screw or a rivet. The fixed pulley 18a is rotatably attached to the base 30. The cords 11a to 11b are moved along the guide groove of the fixed pulley 18a by the guide rollers 31 and 32. The connector 11d is attached to the tip of the cord 11a and is connected to the connector on the seat plate switch 10 side. The connector 11e is attached to the tip of the cord 11c and connected to the control device 8. The cord 11c is fixed to the base 30 via the rubber bush 33. The cord 11 a is fixed to the seat plate switch 10 via the rubber bush 34.
[0022]
As described above, the cord 11a is provided so as to form a predetermined angle φ1 with respect to the guide rails 3 and 4, when the shutter curtain 2 is stored, the angle φ1 is substantially (90 °) and the cord 11a is accordingly accompanied. This is to reduce the length of contact with the fixed pulley 18a as much as possible. Conversely, when the cord 11a is provided so as to be substantially parallel to the guide rails 3 and 4, the angle φ1 is substantially 0 °, and the length of the cord 11a contacting the fixed pulley 18a is increased. If the contact length increases, the contact area between the cord 11a and the fixed pulley 18a increases, the stress applied to the cord 11a increases, and the life of the cord 11a may be shortened. is there.
[0023]
FIG. 8 is a view of the relationship between the cord 11a connected to the seat plate switch 10 of FIG. 1 and the fixed pulley 18c as viewed from the winding shaft 5 side. In FIG. 8, the tip of the cord 11a is connected to the seat switch 10 side. As shown in FIG. 8 (A), it is most desirable that the cord 11a is positioned on the extended line of the guide groove of the fixed pulley 18a. However, depending on the actual shape of the seat plate switch 10, FIG. As shown to (B), the attachment position of the code | cord | chord 11a may shift | deviate by y1 to a perpendicular | vertical (y) direction with respect to an opening surface. Further, in conjunction with the opening / closing operation of the shutter curtain 2, the seat plate portion may swing in the vertical (y) direction with respect to the opening surface. Accordingly, as shown in FIG. 8B, the cord 11a crosses at an angle θ1 with respect to the extension line of the guide groove of the fixed pulley 18a. Here, the crossing angle θ1 is θ1 = tan ^-1 It can be expressed by (y1 / x1).
[0024]
As shown in FIGS. 8A and 8B, when the attachment position of the cord 11a is sufficiently away from the fixed pulley 18a in the x direction as x1, there is no problem because the crossing angle θ1 is sufficiently small. However, as shown in FIG. 8C, if the attachment position of the cord 11a is like the position x2 close to the fixed pulley 18a side, the crossing angle θ2 also becomes large, and the cord 11a is opened during the opening / closing operation of the shutter curtain 2. There is a risk of being pinched between the fixed pulley 18a and the guide roller 31 or the cord 11a coming off the guide groove of the fixed pulley 11a. Accordingly, it is preferable that the attachment position of the cord 11a is such that the aforementioned crossing angle θ1 is about 30 ° or less. The intersection angle θ1 of 30 ° means that the ratio (y1 / x1) between the attachment position x1 of the cord 11a and the maximum deflection width y1 in the vertical direction of the attachment position should be smaller than ½. Means. Further, the crossing angle θ1 needs to be equal to or less than the maximum angle at which the cord 11a is not sandwiched between the fixed pulley 18a and the guide roller 31. In other words, the crossing angle θ1 needs to be equal to or less than the maximum angle at which the cord 11a does not come off the guide groove of the fixed pulley 18a.
[0025]
FIG. 9 is a diagram showing a state when both the movable pulley and the flat bar shown in FIG. 6 are housed in the rail. When the movable pulley 18b and the flat bar 19 are stored in the rail 3, since the flat bar 19 is long in the direction along the rail 3, the winding shaft 5 is not at a high position sufficiently separated from the lower surface of the shutter case 1. In some cases, the flat bar 19 and the movable pulley 18b cannot be accommodated in the rail 3. Therefore, it is preferable that the movable pulley and its weight means can be accommodated in the rail 3 even when the winding shaft 5 is at a low position close to the lower surface of the shutter case 1 without being so far away from the lower surface.
[0026]
FIG. 10 is a diagram showing another embodiment of the shutter device provided with the obstacle detection device of the present invention. FIG. 11 is a diagram showing details of the wiring routing means including the cord, fixed pulley, movable pulley and chain type weight of FIG. FIG. 12 is a front view of FIG. In other words, this wiring routing means allows the movable pulley and its weight means to be easily accommodated in the rail 3 even when the winding shaft 5 is at a low position close to the lower surface of the shutter case 1 without being far away from the lower surface of the shutter case 1. Is.
[0027]
If the weight means is long like the flat bar 19 as described above, the take-up shaft 5 must be at a high position sufficiently separated from the lower surface of the shutter case 1 when the weight means is housed in the rail 3. Therefore, as shown in FIG. 10, instead of the flat bar 19, a chain type weight 60 serving as weight means is used. The total weight of the chain type weight 60 is almost the same as that of the flat bar 19, and its shape can be flexibly deformed. That is, the chain-type weight 60 is configured to be able to deform its entire shape by an assembly of a plurality of members. Therefore, even when the winding shaft 5 is at a low position close to the lower surface of the shutter case 1 without being far away from the lower surface of the shutter case 1, the chain type weight 60 can be compactly deformed and stored in the rail 3.
[0028]
When the chain-type weight 60 is stored in the rail 3, it may be inserted from the upper surface side of the rail 3, or the chain-type weight 60 is moved laterally from left to right in FIG. You may make it accommodate. In FIG. 10, the chain type weight is described as an example in which the entire shape can be deformed by an assembly of a plurality of members. However, a plurality of weight pieces connected by a ring or the like or the like Needless to say, it is also possible to use a thing (for example, a bag enclosing sand, pebbles, cobblestones, pebbles glass or the like, or clay whose whole shape can be deformed alone). Further, in FIG. 10, the case where both ends of the chain type weight 60 are connected to the movable pulley 18b side has been described, but only one end of the plurality of chain type weights may be connected to the movable pulley 18b side. Thus, even if the winding shaft 5 is in a low position that is not so far away from the lower surface of the shutter case 1 and close, the movable pulley and its weight means can be stored in the rail 3, so that these are stored. The overall size of the shutter case 1 can be reduced.
[0029]
In the above-described embodiment, the case where the shutter curtain is drawn out from above by the descending method has been described. However, the present invention can be similarly applied even when the shutter curtain is drawn out by the ascending method. Furthermore, the present invention can be similarly applied even if the shutter-like opening / closing member is extended by a horizontal pulling method or is extended by a horizontal method. Examples of the opening / closing device include a shutter device, a blind device, a roll screen device, a hanging curtain device, a sliding door device, a moving partition device, an awning device, and a waterproof plate device. Further, the material of the opening / closing member as the opening / closing means may be any as long as it is suitable for the purpose of use. Specifically, it can be made of metal, wood, plastic, cloth, or a composite of these.
[0030]
In the above-described embodiment, the seat plate switch has been described as an example of the detection means. However, the seat plate switch detects an obstacle by contacting the obstacle. It may be capable of detecting an obstacle. For example, as an object that detects an obstacle without contact, an infrared light emitting element and a light receiving element are provided on both sides of the opening / closing means, and the obstacle is detected when the infrared light is blocked. There is. Further, the detecting means may be one that detects the opening / closing position of the shutter curtain, a heat sensor that detects the temperature of the shutter curtain itself, or one that detects the locking / unlocking state of the shutter curtain.
[0031]
In the above-described embodiment, the guide rails 3 and 4 that are fixedly provided on both sides of the shutter curtain have been described. However, the present invention is not limited to this, and one side is movable and installed in conjunction with the operation of extending the shutter curtain. Even if it is a movable rail type guide rail and the other is a fixedly provided guide rail, the above-described wiring routing means is provided on the fixedly provided guide rail side. It is applicable similarly by providing.
[0032]
In the above-described embodiment, the case where the wiring routing means is arranged in the guide rail 3 has been described, but the wiring routing means may be arranged above the lintel 9. In this case, a means for applying an urging force to the code is required. For this, an urging means as shown in Japanese Patent Application No. 2001-318677 filed earlier by the applicant of the present application may be used. .
[0033]
Furthermore, in the above-described embodiment, the case where the cord 11a is provided to form the predetermined angle φ1 with respect to the guide rails 3 and 4 has been described, but the cord 11a and the guide rails 3 and 4 are substantially parallel to each other. In addition, a new fixed pulley may be provided on the lintel 9 above the attachment position of the cord 11a. In this case, the angle of the attachment position between the new fixed pulley and the fixed pulley 18a may be set to be equal to or smaller than the maximum angle at which the cord 11a is not sandwiched between the fixed pulley 18a and the guide roller 31.
Further, the fixed pulley 18a (fixed guiding means) is configured to be capable of swinging, turning, swinging, etc., so that slight angle adjustment and position adjustment are automatically performed following the movement of the opening / closing means. It may be performed.
[0034]
【The invention's effect】
As described above, according to the switchgear of the present invention, there is an effect that wiring means such as a lead wire can be wired without being damaged by coming into contact with other members.
