Description

  The present invention relates to a shutter device having a slat curtain.

In recent years, an intruder who cuts a slat curtain of a shutter device with a saw blade is increasing. Patent document 1 is disclosing the shutter apparatus which copes with the cutting | disconnection by an intruder. This shutter device has a slat curtain formed by assembling a plurality of slats so that they can be bent, and an opening / closing drive mechanism for opening and closing the slat curtain. The slat has an engagement end portion that engages adjacent slats so as to be bendable. The adjacent slats are always connected by the engagement between the engagement ends. In this case, the connecting portion between the adjacent slats is connected so that it can be bent. Therefore, the flexibility of the slat curtain is ensured so that the slat curtain can be wound. Here, a minute space is formed by the facing ends of the engaging ends of the adjacent slats. The minute space is formed so as to extend in the longitudinal direction of the slat. A reinforcing member having a rod shape that is difficult to cut with a saw blade is inserted into the minute space to strengthen the slat curtain against an intruder.
JP 2006-161493 A

  In the shutter device described above, the adjacent slats are always connected by the connection of the engagement ends formed at the ends of the slats. And the engagement edge part which engages the adjacent slat mutually faces each other, and forms micro space. In order to effectively use this minute space, a reinforcing member difficult to cut with a saw blade is inserted into this minute space. For this reason, depending on the cross-sectional shape, size, and the like of the reinforcing member, the flexibility of adjacent slats may be hindered. As a result, there exists a possibility of inhibiting the flexibility of the slat curtain formed by connecting several slats. Therefore, there is a great restriction on the shape such as the cross-sectional shape of the reinforcing member and the size such as the cross-sectional size. As the reinforcing member, a plate-shaped member cannot be practically used, and is limited to a rod-like shape. This originates in the crime prevention structure which has inserted the reinforcement member which makes | forms a rod shape in the micro space formed by the facing surface of the engaging edge parts of adjacent slats.

  The present invention has been made in view of the above circumstances, and by providing a slat with a cutting restraining member such as a reinforcing member that obstructs a cutting action by an intruder or the like, security against the intruder is improved. On the other hand, it is an object of the present invention to provide a shutter device that is advantageous in reducing the restriction on the shape such as the cross-sectional shape of the cutting suppressing member and the size of the cross-sectional size.

  A shutter device according to the present invention includes a slat curtain formed by bending a plurality of slats forming a shutter so as to be bendable, and an opening / closing drive mechanism for opening and closing the slat curtain, and among the plurality of slats forming the slat curtain At least one slat is provided with a cutting restraining member that restrains the cutting of the slat, and the cutting restraining member has engagement end portions that engage adjacent slats among the slats facing each other. It is arranged in a region other than the space to be formed.

  The slat is provided with a cutting suppressing member having a function of suppressing cutting. The arrangement is such that the cutting restraining member is embedded in the wall of the slat, the form disposed on the indoor space side of the slat, the form disposed on the outdoor space side of the slat, the accommodating chamber inside the slat In the case where is formed, it means to include a form arranged in the storage chamber. For this reason, even if an intruder or the like tries to cut the slat curtain with a cutting means such as a saw blade, cutting of the slat is suppressed.

In addition, the cutting suppressing member is preferably formed of a material having a higher melting point than the material of the slat, for example, at least one material of metal, glass, and sintered ceramics. If the melting point is high, it is easy to cope with cutting by heat. The cutting suppression member is preferably formed of at least one of a rod-like member, a plate-like member, a wire member (including a rope), a net-like member, and a rolling element assembly. A rolling element having a small diameter can be adopted, and a spherical body, a cylindrical body, and a cylindrical body are exemplified. Upon one of the slat, the cutting suppressing member has a plurality of arranged, one cutting suppressing member that is disposed in a position different from the other cutting suppressing member. This is because there are multiple disconnection failure points.

  In order to avoid local concentration of the cutting location in the cutting suppressing member, it is preferable that the cutting suppressing member is disposed so as to be movable relative to the slat. Even if a cutting means such as a saw blade tries to cut the cutting restraining member, if the cutting restraining member moves relative to the slat, the cutting restraining member becomes easy to move relative to the cutting means such as the saw blade. As a result, the cutting location in the cutting suppressing member is not stable, which is advantageous in avoiding local concentration of the cutting location. Therefore, cutting by a cutting means such as a saw blade is delayed or disabled. In this sense, the slat is exemplified by a configuration including a rotation support portion that supports the cutting suppressing member so as to be rotatable relative to the slat. The slat is exemplified by a configuration including a movement support portion that supports the cutting suppressing member so as to be movable relative to the slat along the longitudinal direction of the slat. Moreover, the form in which the slat is provided with the rotation support part which supports a cutting | disconnection suppression member so that relative rotation is possible is illustrated.

The cutting restraining member has an insertion hole and extends along the longitudinal direction of the slat, and is inserted into the insertion hole of the first cutting restraining member and extends along the longitudinal direction of the slat. It is preferable to provide the 2nd cutting | disconnection suppression member. Second cutting suppressing member, in the insertion hole of the first cutting suppressing member, that is inserted so as to be relatively displaced with respect to the first cutting suppressing member.

  The slat preferably includes a slat body having a screw attachment hole to which the attachment screw is attached, and a slat cover connected to the slat body by attaching the attachment screw to the screw attachment hole of the slat body. It is preferable that the cutting suppressing member is arranged to be movable or rotatable in the screw mounting hole of the slat body. In this case, the existing screw mounting hole can be used effectively.

It is preferable that a buffer coating such as rubber or resin is laminated on the cutting suppressing member. Even if the cutting suppression member moves, abnormal noise is suppressed. Adhesive receiving portion breakable accommodates the adhesive can be adhered to the cutting means, such as a saw blade that provided on the slats. The adhesive is advantageous in reducing the cutting ability of a cutting means such as a saw blade. The adhesive accommodating portion is preferably disposed on the back surface of the portion of the slat that bulges toward the outdoor space. In this case, when the intruder or the like cuts the slats by a cutting means such as a saw blade, the adhesive container is damaged early in the cutting action. For this reason, an adhesive agent can be made to adhere to cutting means, such as a saw blade, at an early stage, and the cutting capability of a cutting means can be reduced. Therefore, it becomes advantageous to reduce the cutting ability of cutting means such as a saw blade early in the cutting action. The slat curtain may be a blind type in which the slat is opened blindly for lighting, ventilation, or the like when the slat curtain is closed, or a non-blind type in which the slat cannot be opened.

  According to the present invention, when the slat curtain is closed, even if an intruder tries to cut the slat curtain by a cutting means such as a saw blade, the cutting of the slat constituting the slat curtain is suppressed by the cutting suppressing member. Is done. For this reason, intrusion by an intruder or the like becomes difficult or impossible.

  Furthermore, the cutting | disconnection suppression member is arrange | positioned in the area | regions other than the space formed so that the engagement edge parts which engage the adjacent slats among each other face each other. For this reason, even if it changes the cross-sectional shape, size, etc. of a cutting | disconnection suppression member, the possibility of inhibiting the flexibility of adjacent slats is reduced. As a result, the possibility of hindering the flexibility of the slat curtain is reduced. Therefore, the degree of freedom in which the shape such as the cross-sectional shape of the cutting suppressing member and the size such as the cross-sectional size can be changed can be increased. Accordingly, the degree of freedom for adjusting the cutting suppression member to a shape, size, etc. suitable for crime prevention is increased. Therefore, as a cutting suppression member, a rod-like member (including a straight bar and a bent bar), a plate-like member (including a flat plate and a corrugated plate), a wire member (including a rope), a net-like member, a rolling element assembly, etc. It can be arbitrarily adopted.

  Hereinafter, the best mode for carrying out the invention will be described based on examples.

  FIG. 1 schematically shows a front view of a shutter device installed on a structure so as to open and close an opening of the structure such as a building. The shutter device includes a shutter curtain 1 formed by arranging a plurality of slats 6 along the height direction, a horizontal winding body 2 that winds up the shutter curtain 1, and a winding body 2 that rotates. A motor 3 as a drive source that is a main element of the drive mechanism, a horizontal frame 4 that rotatably holds the winding body 2, and two vertical struts 5 that are provided on both sides of the shutter curtain 1. I have. A switch (not shown) for controlling the motor 3 is provided. When the motor 3 is driven by the switch and the winding body 2 rotates in one direction around the rotation center 2x, the shutter curtain 1 is wound around the winding body 2. When the motor 3 reversely moves by the switch and the winding body 2 rotates in the reverse direction, the shutter curtain 1 is unwound from the winding body 2. The vertical support 5 guides the lifting and lowering of the end of the shutter curtain 1. The winding body 2 and the motor 3 constitute an opening / closing drive mechanism that opens and closes the shutter curtain 1. The slat 6 extends between the two vertical struts 5 along the left-right direction (L direction). The winding body 2 or the motor 3 is provided with a brake portion 20 that disables the rotation of the winding body 2. FIG. 1 is a schematic diagram only, and the number of slats 6 is not limited to that shown in FIG. As shown in FIG. 1, chain-like linear coupling members 7 are respectively provided on the left and right sides of the shutter curtain 1. The linear connecting member 7 connects ends of the slats 6 provided adjacent to each other in the height direction (arrow H direction) of the shutter device, and can be wound up and down on the winding body 2. Thereby, the linear connection member 7 can be expanded and contracted along the height direction (arrow H direction).

  FIG. 2 shows a front view of one slat 6. FIG. 3 shows a cross section of the slat 6. As shown in FIG. 3, the slat 6 includes an outer wall 601 that can face the outdoor space X1, an inner wall 602 that can face the indoor space, a hollow chamber 610 defined by the outer wall 601 and the inner wall 602, and an outer wall 601. It has a second continuous wall 622 that connects the inner wall 602 and partitions the hollow chamber 610 into a thin flat first hollow chamber 611 and a thin flat second hollow chamber 612. The sectional space volume of the lower first hollow chamber 611 is larger than the sectional space volume of the upper second hollow chamber 612. As shown in FIG. 3, the outer wall 601 of the slat 6 has a bulging portion 604 that can face the outdoor space X1. The inner wall 602 has a recess 605 that can face the indoor space X2. The continuous wall 620 includes a first continuous wall 621 and a first continuous wall 622. The slat 6 is formed by extruding a material such as aluminum with the same cross-sectional shape along the longitudinal direction (arrow L direction) of the slat 6. Therefore, the first hollow chamber 611 and the second hollow chamber 612 are extended in the same cross-sectional shape along the longitudinal direction (arrow L direction) of the slat 6.

  The shutter device is a blind shutter device, and the slat 6 can be opened and closed for ventilation, lighting, and the like in a state where the slat curtain 1 is closed. In the cross section of the slat 6 (FIG. 3), the opening / closing movement direction of the slat curtain 1 is shown as an arrow H direction. A convex fitting portion 60 is formed as an engagement end portion at one end portion in the arrow H direction of the slat 6. At the other end of the slat 6 in the direction of the arrow H, a concave fitted portion 61 that can be fitted with the convex fitting portion 60 is formed as a mating engagement end portion. When the slat curtain 1 is closed, the convex fitting part 60 of one slat 6 and the concave fitting part 61 of the other slat 6 of the slats 6 provided adjacent to each other are fitted together. Facing each other, a space ME is formed (see FIG. 3). According to such a present Example, when the slat curtain 1 is closed, the slats 6 which adjoin each other in the opening-and-closing movement direction (arrow H direction) of the slat curtain 1 are fitted and engaged. As a result, the rigidity of the closed slat curtain 1 is increased, and the crime prevention property is improved.

  As shown in FIG. 2, a cutting suppression member 700 that suppresses complete cutting of the slat 6 is disposed in the hollow chamber 610 of the slat 6. A gap 619 is formed between the longitudinal end 6r of the slat 6 and the longitudinal end of the cutting suppressing member 700, and the cutting suppressing member 700 extends in the longitudinal direction (arrow L direction) of the slat 6. It is possible to move along. The cutting restraining member 700 is an obstacle to a cutting means such as a saw, extends along the longitudinal direction of the slat 6 (arrow L direction), and a plurality of slats are provided per slat. Yes. The cutting suppression member 700 includes a first cutting suppression member 701 extending along the longitudinal direction (arrow L direction) of the slat 6 and a second extending along the longitudinal direction (arrow L direction) of the slat 6. A cutting suppression member 702.

  As shown in FIG. 3, the first cutting suppression member 701 is disposed in the first hollow chamber 611 of the slat 6 so as to be movable relative to the slat 6 in the arrow T direction that is the thickness direction of the slat 6. The second cutting suppression member 702 is disposed in the second hollow chamber 612 of the slat 6 so as to be movable relative to the slat 6.

  Specifically, the first cutting suppressing member 701 can move relatively in the first hollow chamber 611 both in the thickness direction of the slat 6 (arrow T direction) and in the longitudinal direction of the slat 6 (arrow L direction). Further, the first cutting suppressing member 701 can be relatively moved in the first hollow chamber 611 even in the oblique direction with respect to the thickness direction (arrow T direction) and the longitudinal direction (arrow L direction) of the slat 6. Even if an intruder or the like existing in the outdoor space X1 tries to cut the first cutting restraining member 701 with a cutting means such as a saw blade, the first cutting restraining member 701 is one-dimensional with respect to the slat 6 in the first hollow chamber 611. If the two-dimensional or three-dimensional relative movement is performed, the first cutting suppressing member 701 can be relatively moved relative to the cutting means such as a saw blade. As a result, the part of the first cutting suppression member 701 where the cutting means such as a saw blade contacts the first cutting suppression member 701 varies with time. For this reason, in the 1st cutting | disconnection suppression member 701, a cutting location does not concentrate but it becomes unstable. Therefore, the cutting action of cutting the first cutting suppressing member 701 is greatly delayed or made impossible.

  Further, the second cutting suppressing member 702 can relatively move in the second hollow chamber 612 both in the thickness direction of the slat 6 (arrow T direction) and in the longitudinal direction of the slat 6 (arrow L direction). Further, the second cutting suppressing member 702 can be relatively moved in the second hollow chamber 612 even in the oblique direction with respect to the thickness direction (arrow T direction) and the longitudinal direction (arrow L direction) of the slat 6. Even if an intruder or the like existing in the outdoor space X1 tries to cut the second cutting restraining member 702 by a cutting means such as a saw blade, the second cutting restraining member 702 is one-dimensional with respect to the slat 6 in the second hollow chamber 612. If the two-dimensional or three-dimensional relative movement is performed, the second cutting suppression member 702 can be relatively moved relative to the cutting means such as a saw blade. As a result, the part of the second cutting suppression member 702 where the cutting means such as a saw blade contacts the second cutting suppression member 702 varies. Therefore, the part where the cutting means such as a saw blade comes into contact with the second cutting suppressing member 702 varies. As a result, in the second cutting suppressing member 702, the cutting portions are not concentrated and become unstable. Therefore, the cutting action by an intruder or the like is greatly delayed or made impossible.

  As shown in FIG. 3, the 1st cutting | disconnection suppression member 701 and the 2nd cutting | disconnection suppression member 702 are engagement end parts (fitting part 60 and to-be-fitted) which engage the adjacent slats 6 among the slats 6. As shown in FIG. 61) is arranged in a region MB other than the narrow space ME formed by facing each other. Compared to the narrow space ME, the region MB of the slat 6 has a large area, so that the degree of freedom for disposing the first cutting suppression member 701 and the second cutting suppression member 702 is increased. Accordingly, the degree of freedom of the shape and position of the first cutting suppression member 701 and the second cutting suppression member 702 is increased. As shown in FIG. 3, the 1st cutting | disconnection suppression member 701 and the 2nd cutting | disconnection suppression member 702 are plate-shaped members. The first cutting suppression member 701 and the second cutting suppression member 702 are made of a metal harder than a material of the slat 6 (for example, aluminum alloy or iron-based alloy) or a material having a higher melting point (for example, metal, glass, sintered ceramics, etc.). At least one material). Glass, sintered ceramics, etc. have hardness and higher melting point than the material of the slat 6. Examples of the metal include iron, titanium, and cemented carbide. Examples of the iron system include carbon steel (including carburized steel) and alloy steel, and the hardness can be increased by performing a heat treatment such as quenching. A hard metal can easily cope with mechanical cutting. If the melting point is high, it is easy to cope with cutting by heat. If the material of the 1st cutting | disconnection suppression member 701 and the 2nd cutting | disconnection suppression member 702 is glass, since cutting means, such as a saw blade, are easy to slide, Furthermore, since hardness is hard and melting | fusing point is high, cutting action is greatly Delayed or disabled. Moreover, if the material of the 1st cutting | disconnection suppression member 701 and the 2nd cutting | disconnection suppression member 702 is a hardening material and sintered ceramic, since hardness is hard and also melting | fusing point is high, it cut | disconnects by cutting means, such as a saw blade and fusing. And the cutting action is greatly delayed or impossible. Here, the first continuous wall 621, the first continuous wall 622, the inner wall 602, and the outer wall 601 formed in the slat 6 are extended along the longitudinal direction (arrow L direction) of the slat 6, Therefore, the cutting suppressing member 700 can function as a movement support portion that supports the slat 6 so as to be movable relative to the slat 6 along the longitudinal direction (arrow L direction) of the slat 6.

  As described above, according to the present embodiment, when the slat curtain 1 is closed (see FIG. 1), even if an intruder tries to cut the slat curtain 1 with a cutting means such as a saw blade, Even if the outer wall 601 is damaged, the first cutting suppression member 701 and the second cutting suppression member 702 function as an obstacle to cutting means such as a saw blade and fusing. Thereby, complete cutting of the slat 6 is suppressed. For this reason, intrusion by an intruder or the like becomes difficult. In particular, according to the present embodiment, the first cutting suppressing member 701 and the second cutting suppressing member 702 are accommodated in the hollow chamber 610 of the slat 6 so as to be movable relative to the slat 6. For this reason, when the cutting means such as a saw blade tries to cut the first cutting suppressing member 701, the first cutting suppressing member 701 moves relative to the slat 6 and the cutting means. As a result, the contact portion of the cutting means such as a saw blade in the first cutting suppressing member 701 varies with time. Therefore, the cutting location in the first cutting suppressing member 701 becomes unstable, local concentration of the cutting location is avoided, and the cutting action by an intruder or the like is likely to be delayed or impossible. If the cutting object is to be cut by a cutting means such as a saw blade, the cutting progress is fast if the cutting object is fixed. On the other hand, when the object to be cut is moved by a cutting means such as a saw blade, the progress of the cutting is significantly delayed or cannot be cut.

  Further, in this embodiment, when the cutting means such as a saw blade tries to cut the second cutting restraining member 702, the second cutting restraining member 702 is easily moved relative to the cutting means such as the slat 6 and the saw blade. Become. As a result, the cut portions in the second cutting suppressing member 702 are not concentrated, so that the second cutting suppressing member 702 is not stabilized and the cutting of the second cutting suppressing member 702 is delayed or disabled.

  Further, as shown in FIG. 6, in the direction of arrow T, which is the thickness direction of the slat 6, the first cutting suppressing member 701 is arranged at a position different from the second cutting suppressing member 702, and the amount of deviation ΔX (see FIG. 6). ) It is arranged on the indoor space X2 side. For this reason, even if an intruder or the like cuts the outdoor first cutting suppression member 701, the second cutting suppression member 702 faces the cutting means such as a saw blade as an obstacle. For this reason, cutting becomes more difficult, and the crime prevention property against the cutting action is improved. One slat 6 can have one first cutting suppression member 701. One slat 6 can have one second cutting suppression member 702. However, it is not limited to one.

  Furthermore, according to the present embodiment, the first cutting restraining member 701 and the second cutting restraining member 702 are engaging end portions (the fitting portion 60 and the fitted portion) for engaging adjacent slats 6 among the slats 6. The joint portion 61) is disposed in a region MB (see FIG. 3) other than the space ME formed so as to face each other. For this reason, even if the cross-sectional shape and size of the cutting suppressing member 700 are changed, the possibility of hindering the flexibility of the slats 6, that is, the flexibility of the slats 6 constituting the slat curtain 1 is reduced. Accordingly, it is possible to increase the degree of freedom in which the shape such as the cross-sectional shape and the size such as the cross-sectional size of the first cutting suppressing member 701 and the second cutting suppressing member 702 can be changed. Therefore, the degree of freedom for adjusting the first cutting suppression member 701 and the second cutting suppression member 702 to a shape and size suitable for crime prevention is increased. Therefore, the 1st cutting | disconnection suppression member 701 and the 2nd cutting | disconnection suppression member 702 can be made into plate shape. In addition, as a 1st cutting | disconnection suppression member and a 2nd cutting | disconnection suppression member, not only flat plate shape but corrugated plate shape may be sufficient, Furthermore, rod shape, pipe shape, linear shape, corrugated plate shape, wire shape (rope shape), net shape It is also good.

  FIG. 7 shows a second embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. FIG. 7A shows a cross section of the first cutting suppressing member 701A and the second cutting suppressing member 702A. As shown in FIG. 7A, the outer wall surfaces of the first cutting suppression member 701A and the second cutting suppression member 702A are covered with a buffer coating 730 having a buffer function. The buffer coating 730 is formed by laminating rubber, soft resin, or soft tape. Even when the first cutting suppression member 701A and the second cutting suppression member 702A move in the accommodation chamber 610 of the slat 6 by opening and closing the slat curtain 1, the noise is reduced. The buffer coating 730 can be formed on at least one of the outer wall surfaces of the first cutting suppression member 701A and the second cutting suppression member 702A.

  FIG. 7B shows a cross section of the corrugated first cutting suppression member 701B and the corrugated second cutting suppression member 702B. Even if a cutting means such as a saw blade comes into contact with the corrugated first cutting suppression member 701B and the corrugated second cutting suppression member 702B from the direction of the arrow WA, the saw blade or the like is formed by the curved surface formed in the corrugated shape. The cutting means can be expected to slide, which is advantageous for delaying or disabling the cutting action.

  FIG. 8 shows a third embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. A plurality of first cutting suppression members 701 are arranged in parallel so as to form a gap space 709 along the longitudinal direction (arrow L direction) of the slat 6 per one slat 6. A plurality of second cutting suppressing members 702 are arranged in parallel so as to form a gap space 709 along the longitudinal direction (arrow L direction) of each slat 6 per slat 6. The gap space 709 allows the first cutting suppression member 701 and the second cutting suppression member 702 to move in the longitudinal direction of the slat 6 (arrow L direction). For this reason, since the positions of the first cutting suppression member 701 and the second cutting suppression member 702 are not concentrated at the time of a cutting action by an intruder or the like, it is not stable and is advantageous for preventing the cutting action.

  FIG. 9 shows a fourth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. For each slat 6, a plurality of first cutting suppression members 701C are juxtaposed in the longitudinal direction of the slat 6 (arrow L direction). Accordingly, the mobility of the first cutting suppressing member 701C is ensured. However, the first cutting suppression member 701C has an intermediate plate portion 705 provided in the middle in the longitudinal direction and having a thickness ta, and a thickness tc provided at both ends in the longitudinal direction (thickness tc is thinner than the thickness ta). And an end plate portion 707. When the first cutting suppression member 701C is accommodated in the storage chamber 610 of the slat 6, the end plate portion 707 of one first cutting suppression member 701C and the end plate portion 707 of the other first cutting suppression member 701C face each other. But overlap. Therefore, when a plurality of first cutting suppression members 701C are arranged in the longitudinal direction of the slat 6 (arrow L direction), the first cutting suppression member 701C moves in the longitudinal direction of the slat 6 (arrow L direction). Even if possible, the end plate portions 707 in the longitudinal direction of the first cutting suppressing member 701C overlap each other. For this reason, although a meandering crank-shaped gap space 709a is formed in the cross section, it is suppressed that a large straight gap space is formed between the end plate portions 707 in the longitudinal direction of the first cutting suppressing member 701C. The Furthermore, since the first cutting suppressing member 701C is in the longitudinal direction, the divided body itself is reduced in weight and easily moved during a cutting action. Therefore, it is advantageous to avoid the concentration of the cut portions.

  According to the present embodiment, as shown in FIG. 9, since the gap space 709a has a meandering shape (crank shape), even if the cutting means such as a saw blade does not enter in the direction of the arrow WA, the cutting means such as a saw blade. Corresponds to the hard material (end plate portion 707) forming the first cutting suppressing member 701C. For this reason, it is suppressed that cutting means, such as a saw blade, approach only into crevice space 709a, and crime prevention nature becomes high. Accordingly, the gap space 709a is suppressed from being a weak point with respect to a cutting means such as a saw blade. Note that the second cutting suppression member 702C can have a similar structure.

  FIG. 10 shows a fifth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. The 1st cutting | disconnection suppression member 701 is formed with hard metals, such as carbon steel and alloy steel. A hard spray coating 750 is formed on at least a part of the first cutting suppressing member 701 by a thermal spraying method such as plasma spraying of a thermal spray material such as a ceramic material or a metal material. The thermal spray coating 750 has a hard hardness, of the first cutting restraining member 701, the outer surface facing the outer wall 601 of the slat 6 (the surface facing the cutting means by an intruder or the like), and further facing the inner wall 602 of the slat 6. It is formed on the inner surface. As a result, it becomes difficult to cut the first cutting suppressing member 701 by a cutting means such as a saw blade. In this case, the cutting action by an intruder or the like tends to be greatly delayed or impossible. Examples of the ceramic material include at least one of alumina, silica, silicon nitride, silicon carbide, zirconia, magnesia, and the like. Examples of the metal material include carbon steel or alloy steel. Since the thermal spray material is quenched at the time of thermal spraying, it is advantageous for increasing the hardness of the thermal spray coating 750. In addition, although the 2nd cutting | disconnection suppression member 702 is not provided in FIG. 10, you may provide.

  FIG. 11 shows a sixth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. The first cutting suppression member 701 and the second cutting suppression member 702 are formed of a large number of hard particles 762 such as sand and sintered ceramics and a base material 764 that embeds and bonds the large number of hard particles 762. Has been. The base material 764 may be any material that can hold the hard particles 762, and examples thereof include metals and resins. Since the hard particles 762 have a hardness that is harder than the material of the slat 6, it is advantageous in reducing the cutting ability of a cutting means such as a saw blade. As a result, it becomes difficult to cut the first cutting suppression member 701 and the second cutting suppression member 702 by a cutting means such as a saw blade. A buffer film may be laminated on the first cutting suppressing member 701 and the second cutting suppressing member 702.

  FIG. 12 shows a seventh embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. A loading material 670 is loaded in the hollow chamber 610 of the slat 6 (the first hollow chamber 611 and the second hollow chamber 612). Examples of the loading material 670 include a resin material (for example, a soft resin or a hard resin), a rubber material, and a polymer-based porous body (foam). When the slat curtain 1 is opened and closed in the direction of arrow H during normal use, the first cutting restraining member 701 operates excessively in the first hollow chamber 611 of the slat 6, and in the second hollow chamber 612 of the slat 6. It is suppressed that the 2nd cutting | disconnection suppression member 702 operate | moves excessively, and abnormal noise is suppressed. In other embodiments, a loading material may be provided to suppress noise generation.

  13 to 15 show an eighth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. The cutting restraining member 700D includes a hard first cutting restraining member 701D formed of a long hollow metal pipe or ceramic pipe having an insertion hole 703 having a circular cross section extending in the longitudinal direction of the slat 6, and the first cutting. And a plurality of hard second cutting suppression members 702D that are movably inserted into the insertion holes 703 of the suppression member 701D. Hard means that the hardness is harder than the material of the slats 6.

  The second cutting suppressing member 702D has a wire shape, and is formed of a hard wire such as a piano wire, a super hard wire, a hardened wire (including a carburized and hardened material), or a ceramic wire (alumina, silica, etc.). . The second cutting suppressing member 702D preferably has a hardness that is harder than that of the first cutting suppressing member 701D. The first cutting suppressing member 701 </ b> D is disposed so as to be relatively movable in both the first hollow chamber 611 and the second hollow chamber 612 of the slat 6.

  The first cutting restraining member 701D extends along the longitudinal direction (arrow L direction) of the slat 6, and the longitudinal direction (arrow L direction) of the slat 6 also in the thickness direction (arrow T direction) of the slat 6. Can also be moved relative to each other in the direction inclined with respect to the arrow T direction and the arrow L direction. For this reason, even if an outside intruder or the like tries to cut the first cutting suppression member 701D by a cutting means such as a saw blade, the first cutting suppression member 701D is one-dimensional with respect to the slat 6 in the hollow chamber 610. Move relative in two or three dimensions. For this reason, the first cutting suppressing member 701D is easily moved relative to the cutting means such as a saw blade. As a result, the cutting portions in the first cutting suppressing member 701D are not concentrated, so that it is not stable and cutting becomes difficult. Cutting action by a cutting means such as a saw blade is greatly delayed or made impossible.

  Further, the second cutting suppression member 702D has an arrow in the insertion hole 703 of the first cutting suppression member 701D, both in the thickness direction of the slat 6 (arrow T direction) and in the longitudinal direction of the slat 6 (arrow L direction). Relative movement is also possible in the direction inclined with respect to the T direction and the arrow L direction. For this reason, in the unlikely event that the first cutting suppression member 701D is damaged by a cutting means such as a saw blade, an outside intruder or the like is obstructed by the hard second cutting suppression member 702D against the cutting means such as a saw blade. It becomes a thing. Furthermore. Even if it tries to cut | disconnect, 2nd cutting | disconnection suppression member 702D moves relative to the slat 6 one-dimensionally, two-dimensionally, or three-dimensionally in the insertion hole 703 of the damaged 1st cutting | disconnection suppression member 701D. For this reason, the second cutting suppression member 702D is easily moved relative to the cutting means such as a saw blade. As a result, the cutting portions in the second cutting suppressing member 702D are not concentrated, so that the cutting action by the cutting means such as a saw blade is greatly delayed or made impossible.

  Furthermore, according to the present embodiment, as shown in FIG. 14, the first cutting suppression member 701 </ b> D and the second cutting suppression member 702 </ b> D are engagement end portions that engage adjacent slats 6 among the slats 6 ( The fitting part 60 and the fitted part 61) are arranged in a region MB other than the space ME formed to face each other. For this reason, even if the cross-sectional shape, size, etc. of 1st cutting | disconnection suppression member 701D and 2nd cutting | disconnection suppression member 702D are changed, the possibility that the flexibility of slat 6, ie, the flexibility of slat curtain 1, may be reduced. The Accordingly, it is possible to increase the degree of freedom in which the shape such as the cross-sectional shape and the size such as the cross-sectional size of the first cutting suppression member 701D and the second cutting suppression member 702D can be changed. Accordingly, the degree of freedom for adjusting the first cutting suppression member 701D and the second cutting suppression member 702D to a shape and size suitable for crime prevention is increased.

  Further, as shown in FIG. 15, a buffer coating 730 made of rubber, soft resin or the like having an abnormal noise prevention function or a buffer function may be formed on the outer wall surface of the first cutting suppressing member 701 </ b> D. A buffer coating 730 may be formed on the outer wall surface of the second cutting suppressing member 702D. The buffer coating 730 is made of rubber, soft resin, porous material or the like having a buffer function.

  Also in this embodiment, the loading material may be loaded into the hollow chamber 610 (the first hollow chamber 611 and the second hollow chamber 612) of the slat 6. Examples of the loading material include a resin material (soft resin or hard resin), a rubber material, and a porous material. When the slat curtain 1 is opened and closed, the first cutting suppression member 701D and the second cutting suppression member 702D are suppressed from operating excessively in the hollow chamber 610 of the slat 6, and noise generation is suppressed. In addition, about the hardness of 1st cutting | disconnection suppression member 701D and 2nd cutting | disconnection suppression member 702D, it does not specifically limit and may be made into the same degree of hardness.

  16 to 18 show a ninth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. As shown in FIG. 16, each slat 6 includes a slat body 6a and a slat cover 6c that is detachably connected to an end portion in the longitudinal direction of the slat body 6a. The slat body 6a has a wall-like screw attachment portion 803 having a screw attachment hole 801. Since the screw attachment portion 803 (attachment portion) and the screw attachment hole 801 (attachment hole) are formed at the same time when the slat 6 is extruded, the screw attachment portion 803 (attachment portion) extends along the longitudinal direction of the slat 6 (arrow L direction). . The screw attachment portion 803 is formed in a wall shape while forming an opening 803x in the second connecting wall 622. The screw attachment portion 803 is continuous with the second continuous wall 622, but is not limited thereto. The screw attachment portion 803 has a substantially C-shaped cross section, but may have a cylindrical shape.

  An attachment screw 800, which is a tapping screw having a function of automatically forming a screw, is detachably attached to the screw attachment hole 801 of the slat body 6a. The mounting screw 800 has a male screw 800r. As can be understood from FIG. 16, the attachment screw 800 is inserted into the screw opening 801a of the slat cover 6c, and the attachment screw 800 is detachably attached to the screw attachment hole 801 of the screw attachment portion 803 (support portion) of the slat body 6a. Thereby, the slat cover 6c is detachably attached to the end of the slat main body 6a in the longitudinal direction (arrow L direction). The slat cover 6c enhances the design of the end portion in the longitudinal direction of the slat 6 and is formed of resin or rubber. The slat cover 6c is attached to the end portion in the longitudinal direction of the slat 6 and Block it.

  As shown in FIGS. 17 and 18, the cutting suppressing member 700E is a rod-like member having a circular cross section, has a hardness (higher melting point) than that of the scrap 6, and has a wall-like screw attachment portion 803 of the slat body 6a. It is inserted into the screw mounting hole 801 of the (supporting portion) so as to be able to enter and exit. Accordingly, the cutting suppressing member 700E is disposed so as to be freely rotatable in the circumferential direction (arrow S direction). Therefore, the screw attachment portion 803 functions as a rotation support portion that rotatably supports the cutting suppressing member 700E. Thus, the cutting suppressing member 700E is a rod-like member having a circular cross section, and is movably inserted into the screw mounting hole 801 of the screw mounting portion 803 (support portion) of the slat body 6a. For this reason, the cutting | disconnection suppression member 700E is arrange | positioned so that a movement along the length direction (arrow L direction) of the slat 6 is possible.

  For this reason, even if the outer wall 601 of the slat 6 is damaged by a cutting means such as a saw blade, the cutting suppressing member 700E having a hardness higher than that of the slat main body 6a becomes an obstacle. For this reason, the cutting action by a cutting means such as a saw blade is greatly delayed or made impossible. In particular, since the cutting restraining member 700E is movably supported, when a cutting means such as a saw blade touches the cutting restraining member 700E, the cutting restraining member 700E moves in the circumferential direction (arrow S direction) or the slat 6. Relative movement along the longitudinal direction (arrow L direction) is possible. For this reason, the cutting | disconnection location in the cutting | disconnection suppression member 700E does not concentrate, but is not stable. Therefore, the cutting action by an intruder or the like is greatly delayed or made impossible.

  According to the present embodiment, the cutting suppressing member 700E is inserted into the screw mounting hole 801 of the wall-shaped screw mounting portion 803 (support portion) of the slat main body 6a and is supported so as to be rotatable in the circumferential direction (arrow S direction). Has been. For this reason, even when the slat curtain 1 opens and closes, excessive movement of the cutting suppressing member 700E is suppressed, which is advantageous in reducing abnormal noise. The screw attachment portion 803 is already formed on the existing slat 6 for attaching the slat cover 6c. For this reason, the existing screw attachment portion 803 can be used effectively in disposing the cutting suppressing member 700E inside the slat 6.

  Furthermore, also in the present embodiment, as shown in FIG. 17 (B), the engagement end portions (the fitting portion 60 and the fitted portion 61) that engage adjacent slats 6 among the slats 6 face each other. The cutting suppressing member 701E is disposed in the region MB other than the space ME formed by For this reason, even if it changes the cross-sectional shape, size, etc. of the cutting | disconnection suppression member 700, possibility that the flexibility of adjacent slats 6 may be inhibited is reduced. As a result, the possibility of hindering the flexibility of the slat curtain 1 is reduced. Therefore, the degree of freedom in which the shape such as the cross-sectional shape of the cutting suppressing member 700E and the size such as the cross-sectional size can be changed can be increased. Therefore, the degree of freedom for adjusting the cutting suppressing member 700E to a shape and size suitable for crime prevention is increased.

  FIG. 19 shows a tenth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. As shown in FIG. 19, the cutting suppressing member 700 </ b> F is a rod-shaped member having a circular cross section, and is inserted into the screw mounting hole 801 of the slat main body 6 a so as to be movable in the longitudinal direction of the slat 6. The outer diameter of the cutting suppressing member 700F is smaller than the inner diameter of the screw mounting hole 801 of the screw mounting portion 803. For this reason, the smooth rotation property of the cutting | disconnection suppression member 700F to the circumferential direction (arrow S direction) is ensured. The screw attachment portion 803 functions as a rotation support portion that rotatably supports the cutting suppressing member 700F. As a result, the mobility of the cutting suppressing member 700F is ensured, and the cutting portions in the cutting suppressing member 700F are not concentrated and are not stable. Therefore, the cutting action by an intruder or the like is greatly delayed or made impossible.

  Further, as shown in FIG. 19, an adhesive container 901 (or oil container) such as a flowable instantaneous adhesive and the like and a breakable adhesive container 900 (or oil container) are provided in the first hollow chamber of the slat 6. 611. For this reason, when an outside intruder or the like breaks the outer wall 601 of the slat 6 by a cutting means such as a saw blade and further breaks the adhesive accommodating portion 900 (or the oil accommodating portion), the instantaneous adhesive having fluidity is used. Or the like can be attached to a cutting means such as a saw blade. When the adhesive 901 such as the instantaneous adhesive adheres to the cutting means such as a saw blade, it can be expected that the operability of the cutting means such as the saw blade is lowered and the cutting ability of the cutting means such as the saw blade is lowered. As the adhesive 901, an adhesive that can exhibit an adhesive force at an early stage is preferable. As a result, the cutting of the slat curtain 1 is delayed or impossible, which is effective for preventing intrusion. The adhesive accommodating portion 900 is supported inside the slat 6 by a second support portion 6x formed inside the accommodating chamber 610 of the slat 6. The adhesive accommodating portion 900 extends along the longitudinal direction of the slat 6. The adhesive accommodating part 900 is arrange | positioned in the back surface side of the bulging part 604 which protrudes most toward the outdoor space X1 among the outer walls 601 of the slat 6.

  Therefore, when the slat 6 is cut by a cutting means such as a saw blade, the cutting means such as the saw blade comes into contact with the bulging portion 604 early in the cutting action. For this reason, when the bulging portion 604 is destroyed by an intruder or the like, the adhesive accommodating portion 900 is destroyed at an early stage of the cutting action, and the adhesive 901 flows out and adheres to a cutting means such as a saw blade. Therefore, the cutting ability of the cutting means such as a saw blade is reduced early in the cutting action. In this sense, the adhesive 901 is preferably firmly attached to a cutting means such as a saw blade. For this reason, it is advantageous to make the cutting action by an intruder or the like significantly delayed or impossible. In another embodiment, an adhesive accommodating portion 900 that accommodates an adhesive 901 such as an instantaneous adhesive and can be broken can be disposed in the slat 6.

  Since the adhesive 901 may deteriorate over time, it is preferable that the adhesive accommodating portion 900 can be replaced with the slat cover 6c (see FIG. 16) removed from the slat main body 6a during maintenance or the like. . Thereby, it is possible to cope with the aging deterioration of the adhesive 901. An adhesive may be used in place of the adhesive 901.

  Further, also in the present embodiment, as shown in FIG. 19, the cutting suppressing member 700 </ b> F is an engagement end portion (fitting portion 60 and fitted portion 61) that engages adjacent slats 6 among the slats 6. It is arranged in a region other than the space ME formed by facing each other. For this reason, even if the cross-sectional shape and size of the cutting suppressing member 700 are changed, the possibility of hindering the flexibility of the slat 6, that is, the flexibility of the slat curtain 1 is reduced. Therefore, the degree of freedom in which the shape such as the cross-sectional shape of the cutting suppressing member 700F and the size such as the cross-sectional size can be changed can be increased. Therefore, the degree of freedom for adjusting the cutting suppressing member 700F to a shape and size suitable for crime prevention is increased. Note that the rod-shaped adhesive accommodating portion 900 may be supported in the slat 6 by being inserted into the screw attachment hole 801 of the screw attachment portion 803 (support portion) of the slat body 6a.

  FIG. 20 shows Example 11. This embodiment basically has the same configuration and function as the ninth and tenth embodiments. In the following, different parts will be mainly described. As shown in FIG. 20, the hollow chamber 610 of the slat 6 accommodates an aggregate of a large number of rolling elements 770 in addition to the cutting suppressing member 700 </ b> F and the adhesive accommodating portion 900. The rolling element 770 is made of hard metal, sintered ceramics, or the like. As a result, the cutting action by a cutting means such as a saw blade is delayed or made impossible, and crime prevention is improved. Further, also in the present embodiment, as shown in FIG. 20, the assembly of rolling elements 770 is an engagement end portion (fitting portion 60 and fitted portion) that engages adjacent slats 6 among the slats 6. Part 61) is arranged in a region MB other than the space ME formed by facing each other. For this reason, the possibility that the flexibility of the slat 6, that is, the flexibility of the slat curtain 1 may be reduced. Since the excessive movement of the rolling element 770 is limited by the adhesive accommodating portion 900, even when the slat curtain 1 is opened and closed, the noise caused by the collision of the rolling element 770 is reduced. The surface of the rolling element 770 may be covered with a soft layer for preventing collision noise. Instead of the adhesive container 900, an oil container that stores oil may be used.

  FIG. 21 shows a twelfth embodiment. The present embodiment basically has the same configuration and effect as the ninth embodiment. In the following, different parts will be mainly described. As shown in FIG. 21, on the back surface of the outer wall 601 of the slat 6 (the side facing the storage chamber 610), a cylindrical shape that supports a bar-shaped cutting suppression member 700K with a hard circular cross section so as to be movable through a gap 601e. The moving support portion 680 is formed. The moving support portion 680 is formed by extruding the slat 6 along the longitudinal direction thereof. The rod-shaped cutting suppressing member 700K is movable in the circumferential direction and the length direction thereof. The movement support portion 680 extends along the longitudinal direction of the slat 6. The plurality of cutting restraining members 700 </ b> K are disposed at positions that are slightly shifted in the thickness direction of the slat 6. The rod-shaped cutting suppressing member 700 </ b> K may be extended over substantially the entire length of the slat 6, or a plurality of rod-shaped cutting suppressing members 700 </ b> K may be provided side by side in the longitudinal direction of the slat 6. In addition, you may form in the back surface (side facing the storage chamber 610) of the inner wall 602 of the slat 6 the movement support part which supports a cutting | disconnection suppression member so that a movement is possible.

  FIG. 22 shows Example 13. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. The shutter device is not a blind shutter device, and the slat 6H does not rotate when the slat curtain 1 is closed. FIG. 22 shows a cross section of the slat 6H. As shown in FIG. 22, a fitting portion 60H is formed as an engaging end portion at one end portion in the height direction (arrow H direction) of the slat 6H. A fitted portion 61H is formed as an engagement end at the other end of the slat 6H in the height direction (arrow H direction). The fitting portion 60H of one slat 6H and the fitted portion 61H of the other slat 6H are always fitted and engaged, and the slat curtain 1 is formed. A support portion 690 is formed in a region other than the fitting portion 60H and the fitted portion 61H in the slat 6H. The cutting suppressing member 700H is movably supported by the support portion 690 via the gap 690r, and is disposed on the indoor space X2 side of the slat 6H. Since the cutting suppressing member 700H is covered with the slat 6H, it cannot be visually recognized by an intruder or the like existing in the outdoor space X1. Even if an intruder or the like breaks the slat 6H with a cutting means such as a saw blade, the plate-like cutting suppressing member 700H becomes an obstacle to the cutting means such as the saw blade. Further, the cutting suppressing member 700H is movable in the longitudinal direction and the thickness direction thereof. For this reason, the cutting action by cutting means such as a saw blade is delayed or made impossible, and the crime prevention property is improved.

  Further, also in this embodiment, as shown in FIG. 22, the cutting suppressing member 700H is an engagement end portion (a fitting portion 60H and a fitted portion 61H) that engages adjacent slats 6 among the slats 6. It is arranged in a region MB other than the space ME formed by facing each other. For this reason, even if the cross-sectional shape and size of the cutting suppressing member 700H are changed, the possibility of hindering the flexibility of the slat 6, that is, the flexibility of the slat curtain 1, is reduced. Therefore, the degree of freedom in which the shape such as the cross-sectional shape of the cutting suppressing member 700H and the size such as the cross-sectional size can be changed can be increased. Therefore, the degree of freedom for adjusting the cutting suppressing member 700H to a shape and size suitable for crime prevention is increased.

  23 and 24 show a fourteenth embodiment. The present embodiment basically has the same configuration and operational effects as the first embodiment. In the following, different parts will be mainly described. In order to avoid complication, hatching is omitted in the drawings. As shown in FIGS. 23 and 24, a hard cutting restraining member 700 is disposed inside the slat 6 so as to be movable in the length direction and the thickness direction thereof. The linear connecting member 7 that conveys the slat 6 includes a first link 71 and a second link 72. The engagement pin 74 of the second link 72 is slidably fitted in the long hole 73 of the first link 71. The vertical strut 5 has a main guide passage 50 and a main rail portion 51 extending along the height direction (arrow H direction), as well as a sub guide passage 53 and a sub rail portion forming the sub guide passage 53. 54. The sub guide passage 53 is arranged in parallel along the height direction (arrow H direction) in parallel with the main guide passage 50. A guide portion 55 is attached to the vertical column 5 so as to connect the main rail portion 51 and the sub rail portion 54. The guide portion 55 is connected to the sub rail portion 54. The sub guide passage 53 and the main guide passage 50 communicate with each other. While the shutter curtain 1 is being rolled down, the amount of fitting between the fitting portion 60 of the slat 6 and the fitted portion 61 is reduced. For this reason, the stopper portion 68 and the stoppered portion 69 of the slat 6 are reduced. Is separated and brought into a non-contact state, and the slats 6 can be rotated relative to each other. Here, each slat 6 is provided with a closing spring 89 (see FIG. 23, a closing biasing member) formed of a torsion coil spring. Since the slat 6 is always urged to close by the urging force of the closing spring 89, the slat 6 descends in a closed state while the shutter curtain 1 is being rolled down.

  Now, the slat rotation mechanism 8 is attached to the vertical column 5. The slat rotation mechanism 8 has a function of rotating a predetermined slat 6 among the plurality of slats 6 constituting the shutter curtain 1. As shown in FIG. 23, the end link 6f of the slat cover 6c is provided with a first link 71 and a rotation link 57 (a rotation member for rotating the slat 6 sideways). The rotation link 57 is integrally attached to the end portion 6f of the slat 6 by a pivot pin 6w so as to rotate integrally with the slat 6. The rotation link 57 can rotate together with the slat 6 with respect to the linear connection member 7 around the pivot pin 6w. A guided pin 59 (engagement member) projects laterally from the rotation link 57. The guided pin 59 corresponds to a part of the slat 6. Here, when the motor 3 is driven in one direction (unwinding direction) in a state where the shutter curtain 1 is wound around the winding body 2, the winding body 2 rotates in the unwinding direction, and the winding body. The shutter curtain 1 wound around 2 is gradually rolled down in the downward direction (arrow H2 direction). Here, the guided pin 59 of the slat 6 enters the main guide passage 50 and descends along the main rail portion 51 in the main guide passage 50. An engagement position KA (see FIG. 23) through which the guided pin 59 passes is provided in the upper part of the main guide passage 50. As shown in FIG. 23, the slat rotation mechanism 8 includes a cam 80 as an operating body having a cam guide surface 81 and an actuator 85 that operates the cam 80. In the cam 80, the actuator 85 is formed of an electromagnetic solenoid, but it may be formed using a motor mechanism or a pneumatic cylinder. As shown in FIG. 23, the cam 80 can rotate in the retracting direction (arrow E2 direction) and the engaging direction (arrow E3 direction) with the cam pin 88 as the rotation center. A cam 80 is connected to the drive rod 86 attached to the actuator 85 via a connecting pin 86 e and a cam return spring 87. The cam 80 is always urged by the cam return spring 87 in the retracting direction (arrow E2 direction). For this reason, in a normal state, the cam guide surface 81 of the cam 80 stands by at the retracted position MA and is set so as not to engage with the guided pin 59 which is a part of the slat 6.

  In the case where the cam 80 is retracted to the retracted position MA as described above, when the shutter curtain 1 wound around the winding body 2 is lowered downward (in the direction of the arrow H2), the linear connecting member 7 The first link 71, the second link 72, and the pivot pin 6 w descend along the main rail portion 51 in the main guide passage 50. Further, the guided pin 59 of the slat 6 does not engage with the cam guide surface 81 of the cam 80, and moves downward (in the direction of arrow H <b> 2) along the main guide passage 50. As a result, the slat 6 moves downward (in the direction of the arrow H2) in a vertical state, that is, in a closed state. The reason is that each slat 6 is always urged by the closing spring 89 in the closing direction (the direction in which the ventilation opening 6e is not formed). Therefore, when the shutter curtain 1 is closed, all the slats 6 are closed in the vertical direction, and the ventilation openings 6e are not formed.

  On the other hand, when the ventilation opening 6e is formed between the slats 6 of the shutter curtain 1, when the shutter curtain 1 wound around the winding body 2 is rolled down in the downward direction (arrow H2 direction), The user operates the switch to turn on the actuator 85. Then, the actuator 85 moves the drive rod 86 in the drive direction (the direction of arrow E1 in FIG. 23). For this reason, the cam 80 rotates against the cam return spring 87 around the cam pin 88 in the engagement direction (in the direction of arrow E3 in FIG. 23), and the cam guide surface 81 of the cam 80 protrudes to the engagement position KA. To do. In this state, the guided pin 59 of the slat 6 descends and passes through the engagement position KA. As a result, as can be understood from FIG. 24, since the guided pin 59 moves along the cam guide surface 81 of the cam 80, the guide pin 59 moves laterally from the main guide passage 50 to the sub guide passage 53 (in the direction of arrow S1 in FIG. ) In contrast, the first link 71, the second link 72, and the pivot pin 6 w of the linear connecting member 7 descend along the main rail portion 51 along the main guide passage 50. As a result, the rotation link 57 rotates together with the slat 6 in the ventilation promotion direction (the direction of arrow F1 in FIG. 24) around the pivot pin 6w.

  Accordingly, the slats 6 are turned sideways, and ventilation openings 6e (see FIG. 24) are formed between the slats 6. The guided pin 59 moves downward (in the direction of arrow H2) along the sub rail portion 54 in the sub guide passage 53 while descending. In this way, the slat 6 moves downward (in the direction of the arrow H2) in a ventilated position, that is, in a state of being sideways. As a result, even when the shutter curtain 1 is fully closed, the slat 6 on the upper side of the shutter curtain 1 is in a ventable position, that is, sideways. Therefore, the ventilation opening 6e that also serves as the visual recognition opening or the daylighting opening is formed.

  (Others) The present invention is not limited to the embodiment described above and shown in the drawings, and can be appropriately modified and implemented without departing from the scope of the invention. Structures and functions specific to one embodiment can also be applied to other embodiments. For example, a sprayed coating can be formed on the cutting suppressing members according to all the embodiments. Moreover, the cutting suppression member which concerns on all the Examples can be formed with glass materials, such as a tempered glass material which has slidability with respect to cutting means, such as a saw blade.
