Description

  The present invention relates to a shutter device having a system in which a shutter curtain is wound around a winding body or a shutter curtain is rolled down from the winding body.

  Conventionally, there has been disclosed a shutter device including a shutter curtain formed by arranging a plurality of slats extending in the left-right direction along the height direction, and a winding body (Patent Documents 1 and 2). . When the winding body rotates in one direction, the shutter curtain is wound around the outer periphery of the winding body. When the winding body rotates in the reverse direction, the shutter curtain wound around the outer periphery of the winding body is unwound. This shutter curtain has a plurality of slats that extend in the left-right direction and are adjacent to each other in the height direction, and a linear connection that is provided at the end of each slat and has flexibility to roll up and down the slats. And a member.

In this case, the slat is made rotatable. When the slat is rotated sideways, the shutter curtain is lifted up in a state where the shutter curtain is closed. At this time, since the actuator is driven, the capturing member operates in the capturing direction, and thereby the control plate moves to the slat side. As a result, the locking pin of the slat that moves up engages with the locking hole of the control plate. Even after the engagement, since the slat moves up, the slat is lifted around the locking hole. As a result, the slats rotate laterally around the locking pin as a rotation center, and an opening is formed between the slats. Therefore, in the shutter device described above, even if the shutter curtain is closed, the opening is formed in the shutter curtain, so that high crime prevention is maintained and air permeability, visibility, or daylighting are ensured. Is done.

  In the shutter device described above, when the slats are rotated to form the openings between the slats, an operation for raising the shutter curtains must be performed in a state where the shutter curtains are closed. Here, the operation of raising the shutter curtain corresponds to the direction of opening the shutter curtain. In order to improve the crime prevention property, it is preferable that the shutter curtain is set in a completely closed state when the shutter curtain is closed. For this reason, when the shutter curtain is closed, it is not preferable to raise the shutter curtain so as to form an opening between the slats.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a shutter device capable of forming an opening between slats while ensuring high crime prevention.

  The present inventor has been developing a shutter device under the above-described problems. And, when the shutter curtain is rolled down rather than when the shutter curtain is raised, if the operation of rotating the slat to form the opening is executed, the opening between the slats is secured while ensuring high crime prevention. The present inventors have found that a shutter device capable of forming a film can be provided, and have completed the present invention based on such knowledge.

That is, the shutter device according to aspect 1 includes a rollable shutter curtain in which a plurality of rotatable slats extending in the left-right direction are arranged in parallel along the height direction, and rotation in one direction. A shutter device comprising: a winding body that winds up the shutter curtain and unwinds the shutter curtain with rotation in a reverse direction; and a drive mechanism that rotates the winding body.
An actuator that engages at least a portion of a slat of the shutter curtain to be rolled down to rotate the slat to form an opening between the slats when the shutter curtain is rolled down;
An operating body switching mechanism that switches the operating body between an engaging position where the operating body engages with a part of the slat and a retracted position where the operating body is retracted with respect to the slat is provided.

  According to this aspect, when the opening is formed between the slats, when the shutter curtain is rolled down, the operating body is switched from the retracted position to the engaged position by the operating body switching mechanism. For this reason, the operating body at the engagement position is engaged with at least a part of the slat of the shutter curtain that is rolled down. As a result, the slats rotate and an opening is formed between the slats. The direction in which the shutter curtain is rolled down corresponds to the closing direction of the shutter curtain. For this reason, the closing property of the shutter curtain is well maintained while the openings are formed between the slats.

  According to this aspect, when the slats are rotated to form the openings between the slats, the shutter curtain is lifted in an operation (shutter curtain) different from the prior art when the shutter curtain is closed. Need not be executed. For this reason, this aspect can form an opening between slats, ensuring high crime prevention property. Openings between the slats can contribute to improvements in air permeability, visibility, daylighting, and the like. The slat is a member having a shape extending in the left-right direction to constitute a shutter curtain.

  According to the shutter device according to aspect 2, in the above-described aspect, the operating body switching mechanism operates against the urging force of the retracting urging member that urges the operating body to the retracted position and the urging force of the retracting urging member. And an actuator for switching the body to the engagement position. In this case, since the operating body is quickly switched to the engaged position by the on-operation of the actuator, the slats can be rotated to form an opening between the slats. If the driving force of the actuator does not act on the operating body, the operating body is quickly switched to the retracted position by the biasing force of the retracting biasing member, so that the operating body does not engage the slat. Examples of the urging member for retraction include a coil spring, a torsion coil spring, a leaf spring, and a foam, but are not limited thereto. Examples of the actuator include a motor, an electromagnetic solenoid, a pneumatic cylinder, and a hydraulic cylinder.

  According to the shutter device according to aspect 3, in the above-described aspect, at least one of the plurality of slats engages with the operating body and rotates the slat when the operating body is switched to the engagement position. A rotation engagement portion is provided, and the slat provided with the rotation engagement portion among the plurality of slats is rotated. In this case, since the rotation engaging portion of the slat engages with the operating body at the engagement position, the slat can be quickly rotated to form an opening between the slats. An opening can be formed by rotating a slat having a rotation engaging portion among a plurality of slats. A slat that does not have a rotating engagement portion is not rotated. The rotation engaging portion can be convex or concave.

  According to the shutter device according to aspect 4, in the above-described aspect, the rotation engagement portion includes the rotation member held by the slat so as to rotate integrally with the slat, and the rotation member held by the rotation member. And an engaging member engageable with the operating body. In this case, since the engagement element of the rotation engagement portion of the slat engages with the operating body at the engagement position, the slat is quickly rotated and an opening is formed between the slats. For example, the engagement element can be in the form of a pin or a ball, but is not limited thereto.

  According to the shutter device according to aspect 5, in the above-described aspect, the shutter curtain has a linear connecting member extending along the height direction and connected to each slat, and the linear connecting member is flexible. It is possible to switch between a flexible state having a property and a high-rigidity state having higher rigidity than the flexible state. In this case, the linear connecting member can be switched between a flexible state having flexibility and a highly rigid state having high rigidity. When winding the linear connecting member around the winding body or unwinding the linear connecting member, the linear connecting member is set in a flexible state. When the shutter curtain is in a closed state, the linear connecting member is in a highly rigid state, and the crime prevention property by the shutter curtain is enhanced.

  According to the shutter device according to aspect 6, in the above-described aspect, when the linear coupling member is raised by rotating the winding body in the winding direction, the linear coupling member is configured to be switched to a flexible state. . In this case, when the linear coupling member is raised by rotating the winding body in the winding direction, that is, when the shutter curtain is opened and wound up, the linear coupling member is switched to the flexible state. Here, according to this invention, when raising a linear connection member, the operation | movement which rotates a slat and forms opening between slats is not performed. Thus, in forming an opening between slats, since a linear connection member is not raised, it can contribute to further improving the crime prevention property by a shutter curtain.

  According to the shutter device according to aspect 7, in the above-described aspect, the linear coupling member can be expanded and contracted along the height direction, and when the linear coupling member is at the extended position, the linear coupling member is expanded. Is in a flexible state, and when the linear connecting member is in a contracted position where the linear connecting member contracts, the linear connecting member is switched to a high-rigidity state, thereby improving crime prevention.

  According to the shutter device according to aspect 8, in the above-described aspect, the linear connecting member pivotally supports the first link attached to the end of the slat and the first link adjacent thereto so as to be rotatable. A link, a long hole provided in one of the first link and the second link and extending in the height direction, and a long hole provided in the other of the first link and the second link along the major axis direction of the long hole. The linear coupling member is set to be extendable and retractable when the fitting body relatively moves along the long diameter direction of the long hole. Since this structure is adopted, the linear connecting member can be expanded and contracted, and can be satisfactorily switched between the extended position (flexible state) and the contracted position (high rigidity state).

  According to the shutter device according to aspect 9, in the above-described aspect, when the shutter curtain is closed, the relative rotation between the adjacent first links is limited to make the linear coupling member in a highly rigid state. It has a dynamic regulation part. In this case, a highly rigid state of the linear connecting member can be obtained satisfactorily and crime prevention is ensured.

  According to the shutter device according to aspect 10, in the above-described aspect, the main rail portion that guides the slat along the height direction while maintaining the slat in the vertical direction, and the slat is raised in a state in which the slat is rotated. A sub rail portion that guides along the direction is provided. With the main rail portion, a vertically oriented slat (a slat that does not form an opening) can be lowered. The rotated slat (the slat in which the opening is formed) can be lowered by the sub rail portion.

  According to the shutter device according to aspect 11, in the above-described aspect, the closing urging member that urges the slat in the direction of closing the opening is provided on the shutter curtain, and the operating body is disposed on the closing urging member. Rotate the slats against. If the operating body and the slat do not engage with each other, the slat is urged by the urging force of the closing urging member in the direction of closing the opening, so that the slat is automatically closed. Examples of the urging member for closing include a coil spring, a torsion coil spring, a leaf spring, and a foam, but are not limited thereto.

  According to the shutter device according to aspect 12, in the above-described aspect, the slat includes an upper fitting portion that engages with a slat adjacent to the upper side, and a lower fitting portion that engages with a slat adjacent to the lower side. When the shutter curtain is closed, the upper fitting portion and the lower fitting portion are fitted. In this case, when the shutter curtain is closed, the upper fitting part of the slat and the lower fitting part of the slat are fitted, so that the rigidity of the boundary between the slats is increased. Therefore, it becomes difficult for foreign matters such as bar to enter the boundary between the slats, and the crime prevention property is improved.

  According to the shutter device according to aspect 13, in the above aspect, the winding body or the drive mechanism has a brake portion that brakes the rotation of the winding body. When the brake unit is activated, the winding body is not rotated. In this case, the extension of the linear connecting member is suppressed, which is advantageous for maintaining the linear connecting member in a highly rigid state, and the crime prevention property is improved.

  According to the shutter device according to aspect 14, in the above aspect, (i) the linear coupling member is provided on the winding body so that it can be wound together with the slats, and has a connecting portion connected to the winding body. (Ii) When a virtual horizontal line passing through the center of rotation of the winding body in the horizontal direction is set, when the shutter curtain is in the fully closed state, the starting point site that is the starting point of separation from the winding body among the linear connecting members is , Arranged below or below the virtual horizon.

  The starting point portion is a starting point that separates from the winding body among the linear connecting members. The starting point portion is arranged at or below the virtual horizontal line. For this reason, when the shutter curtain is closed, it is suppressed that the part by the side of a connection part among linear connection members is located above a virtual horizontal line. Therefore, it is suppressed that the linear connection member wound up by the winding body will be in a low rigidity state. Accordingly, the linear connecting member including the connecting portion is in the contracted position, and the rigidity of the linear connecting member is maintained high.

  According to the present invention, when the operation of lowering the shutter curtain wound around the winding body is performed downward, the operating body switching mechanism rotates the slats to form the openings between the slats. Here, the direction in which the shutter curtain is operated upward corresponds to the direction in which the shutter curtain is opened. On the other hand, the direction in which the shutter curtain is rolled down corresponds to the direction in which the shutter curtain is closed, which is a preferable direction for obtaining high crime prevention. For this reason, according to this invention, opening can be formed between slats, ensuring the high crime prevention property by a shutter curtain.

  Embodiments of the present invention will be specifically described below with reference to the drawings. In order to avoid complication, hatching is omitted in the drawings. 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 winding body 2 that winds up the shutter curtain 1, and a driving mechanism that rotates the winding body 2. A motor 3 that is a base, a horizontal frame 4 that rotatably holds the winding body 2, and two vertical columns 5 that are provided on both sides of the shutter curtain 1 are provided. 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 slat 6 extends between the two vertical struts 5 along the left-right direction (L direction). The winding body 2 or the drive mechanism 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 the ends of the slats 6 provided adjacent to each other in the height direction (arrow H direction) of the shutter device, and can extend and contract along the height direction (arrow H direction). Yes.

  As shown in FIG. 2, the vertical column 5 is provided with a main guide passage 50 in which the linear connecting member 7 moves in the up-and-down direction, and a main rail portion 51 that forms the main guide passage 50. The main guide passage 50 and the main rail portion 51 are extended along the height direction (arrow H direction). The upper part of the main rail part 51 has the expansion part 51p which guides the linear connection member 7. FIG. The linear connecting member 7 can move in the height direction (arrow H direction) along the main rail portion 51 in the main guide passage 50. FIG. 2 shows an arrow view along line II-II in FIG. 1, and mainly shows the linear connecting member 7. FIG. 3 shows an arrow view along the line III-III in FIG. As shown in FIG. 2, the linear connecting member 7 includes a first link 71 having a vertically long shape and a second link having a vertically long shape that pivotally supports a first link 71 provided adjacently in the height direction. 72, a long hole 73 provided in each of the upper end portion and the lower end portion of the first link 71 and extending in the height direction (arrow H direction), and a protruding fitting pin 74 (fitting body) provided in the second link 72 ) As shown in FIG. 2, the upper end portion 7 u of the linear connecting member 7 is connected to the outer peripheral surface 2 p of the winding body 2 by a first bolt 75 and a second bolt 76 as connecting portions. The first bolt 75 is located on the lower side, and the second bolt 76 is located on the upper side of the first bolt 75. A portion of the linear connecting member 7 below the first bolt 75 can be detached from the outer peripheral surface 2p of the winding body 2 in the separating direction (arrow HB direction). A portion of the linear connecting member 7 immediately below the first bolt 75 is a starting point for disengaging the outer peripheral surface 2p of the winding body 2 in the separating direction (the direction of the arrow HB shown in FIG. 2) of the linear connecting member 7. This corresponds to the starting point portion 77. Therefore, when the winding body 2 rotates in the unwinding direction (arrow A2 direction), the part of the linear connecting member 7 below the starting part 77 can be separated from the outer peripheral surface 2p of the winding body 2. . In addition, the intermediate part 7m of the 1st volt | bolt 75 and the 2nd volt | bolt 76 among the linear connection members 7 cannot detach | leave with respect to the outer peripheral surface 2p of the winding body 2. FIG. The first link 71 is connected to the end of the slat 6 in the left-right direction so as to be rotatable with respect to the slat 6 by a pivot pin 6w (connection element). Therefore, the slat 6 is rotatable with respect to the first link 71 in the vertical direction around the pivot pin 6w.

  In FIG. 2, when the winding body 2 is rotated in the winding direction (arrow A1 direction) around the rotation center 2x by the motor 3, the linear connecting member 7 below the winding body 2 is moved upward (arrow). H1 direction) and is gradually wound around the outer peripheral surface 2p of the wound body 2. On the other hand, when the motor 3 reversely moves and the winding body 2 rotates about the rotation center 2x in the unwinding direction (arrow A2 direction), the linear connecting member 7 moves downward (arrow H2 direction). ) And is unwound from the outer peripheral surface 2p of the winding body 2. FIG. 4 shows the operation of the linear connecting member 7. As shown in FIG. 4, the fitting pin 74 is fitted in a long hole 73 having a long diameter and a short diameter. The fitting pin 74 is movable in the long hole 73 along the long diameter direction (arrow B direction) of the long hole 73. Here, as shown in FIG. 4 (B), when a tensile force acts on the first link 71 in the direction of arrow B1 (upward), the upper first link 71 moves to one of the long-diameter direction of the long hole 73 (in the direction of arrow B1). ) And the fitting pin 74 is relatively moved to be positioned on one end side 73 a of the long hole 73. As a result, as shown in FIG. 4B, since the ends 71c of the first links 71 are separated from each other, the linear connecting member 7 is extended in the height direction (arrow H direction), and the linear connecting member 7 is The extended position. When the linear connecting member 7 is extended in this way, as shown in FIG. 4C, the first links 71 can bend in the direction of the arrow R1, and therefore the linear connecting member 7 is wound up. It can be wound on the outer peripheral surface 2p of the body 2. On the other hand, as shown in FIG. 4A, when the pushing force in the direction of arrow B2 (downward) acts on the first link 71, the first link 71 is in the other of the long holes 73 in the long-diameter direction (in the direction of arrow B2). ) Move toward. As a result, the fitting pin 74 relatively moves and moves to the other end 73 c side of the long hole 73. Then, as shown in FIG. 4A, since the ends 71c of the first links 71 approach each other, the linear connecting member 7 is contracted in the length direction, and the linear connecting member 7 is switched to the contracted position.

  As shown in FIGS. 4A, 4 </ b> B, and 4 </ b> C, the second link 72 of the linear connecting member 7 is integrally provided with a plate-like rotation restricting portion 78 by bending. The rotation restricting portion 78 is disposed between adjacent slats 6. The rotation restricting portion 78 is disposed on the indoor 10 side rather than the outdoor 12 side of the linear connecting member 7. FIG. 4A shows a state in which the shutter curtain 1 is closed, that is, the linear connecting member 7 is contracted in the height direction (arrow H direction) to the contracted position (high rigidity state). Show. Thus, at the contracted position, as shown in FIG. 4A, the distance between the portion 71x of the first link 71 and the rotation restricting portion 78 is ΔL1, and the portion 71x of the first link 71 is turned to the rotation restricting portion 78. Is approaching. For this reason, even if the adjacent first links 71 attempt to rotate relative to each other in the direction of the arrow R1 with the fitting pin 74 as the rotation center, the portion 71x of the first link 71 immediately contacts the rotation restricting portion 78. For this reason, the relative rotation of the first links 71 in one direction (the direction of the arrow R1) is limited. Similarly, even if the adjacent first links 71 try to rotate relative to each other in the other direction (arrow R2 direction) with the fitting pin 74 as the rotation center, the first link 71 can be understood from FIG. The end 71c immediately contacts the rotation restricting portion 78. As a result, when the shutter curtain 1 is closed, the rotation restricting portion 78 restricts the relative rotation between the first links 71 provided adjacent to each other. For example, the first links 71 can relatively rotate in the directions of arrows R1 and R2 only by about 3 to 5 degrees, for example. Therefore, when the shutter curtain 1 is closed, the linear connecting member 7 is switched to the high rigidity state (contracted position), and the rigidity of the linear connecting member 7 is increased by the rotation restricting portion 78, and consequently the shutter curtain. The rigidity of 1 is increased. Therefore, the second link 72 having the rotation restricting portion 78 can function as a rigidity reinforcing means. Here, when the shutter curtain 1 is closed, the winding body 2 is restrained by the brake unit 20 so as not to rotate. In this case, even if an intruder tries to lift the shutter curtain 1, the linear connecting member 7 is made highly rigid and is prevented from bending, so that the shutter curtain 1 can be prevented from being lifted, and the crime prevention property is improved.

  FIG. 4B shows a state in which the linear connecting member 7 is extended in the height direction (arrow H direction) and set to the extended position (flexible state). At this time, as shown in FIG. 4B, the portion 71x of the first link 71 is separated from the rotation restricting portion 78 by ΔL2 (ΔL2> ΔL1). For this reason, when the adjacent first links 71 try to rotate relative to each other in the direction of the arrow R1 with the fitting pin 74 as the center of rotation, the first link 71 until the portion 71x of the first link 71 contacts the rotation restricting portion 78. The one link 71 can be relatively rotated in the direction of the arrow R1. Therefore, the first links 71 can be rotated to, for example, a rotation angle of about 60 degrees, and the flexibility of the linear connecting member 7 can be ensured. As a result, the shutter curtain 1 can be easily wound around the outer peripheral surface 2p of the winding body 2. Here, when the shutter curtain 1 is wound around the winding body 2, the winding body 2 rotates in the winding direction (in the direction of arrow A <b> 1 in FIG. 2), so that the first link 71 of the linear connecting member 7 faces upward ( As a result, the linear connecting member 7 is stretched. In such an extended position (flexible state), the rigidity of the linear connecting member 7 is reduced, and the linear connecting member 7 has high flexibility. As a result, the rigidity of the shutter curtain 1 is lowered and the flexibility is increased. Therefore, the shutter curtain 1 can be satisfactorily wound around the outer peripheral surface 2p of the winder 2 (see FIG. 4C).

  In FIG. 2, a virtual horizontal line HA passing through the rotation center of the winding body 2 in the horizontal direction is set. As described above, the starting point portion 77 becomes a starting point that separates from the outer peripheral surface 2 p of the winding body 2 in the linear connecting member 7. Here, when the shutter curtain 1 is in the fully closed state or the pseudo fully closed state, as shown in FIG. 2, the starting point portion 77 is set so as to be arranged on the virtual horizontal line HA or below the virtual horizontal line HA. Yes. That is, the starting portion 77 of the linear connecting member 7, that is, the portion immediately below the first bolt 75 is a virtual horizontal line HA passing through the rotation center 2 x of the winding body 2 in the horizontal direction or below the virtual horizontal line HA. The number of the first links 71 and the slats 6 is set so as to be arranged in the above. According to this embodiment, as shown in FIG. 2, when the shutter curtain 1 is in the fully closed state or the pseudo fully closed state, the starting point portion 77 is prevented from being positioned above the virtual horizontal line HA. Is done. As a result, the uppermost first link 71 of the linear connecting member 7 is prevented from being disposed on the arcuate outer peripheral surface 2p of the winding body 2. For this reason, when the shutter curtain 1 is in the fully closed state or the pseudo fully closed state, the linear connecting member 7 is in the contracted position, and thus has high rigidity. Therefore, the winding body 2 is prevented from lifting the uppermost first link 71 of the linear connecting member 7. As a result, the force FA in the pushing direction that causes the linear connecting member 7 to act downward can be applied to the linear connecting member 7 in a highly rigid state. Further, when the shutter curtain 1 is closed, the lower end portion of the shutter curtain 1 is constrained, so that the first link 71 and the second link 72 of the partial linear connecting member 7 are linear. Downward gravity acts on the connecting member 7. As a result, the linear connecting member 7 is prevented from reaching the extended position (flexible state). Therefore, when the shutter curtain 1 is in the fully closed state or the pseudo fully closed state, the first links 71 of the linear connecting member 7 are brought close to each other, and the linear connecting member 7 is in its contracted position (high rigidity state, FIG. 4). (See (A)) can be easily set. Thus, when the linear connection member 7 is set to a highly rigid state, the crime prevention property with respect to an intruder is improved. Here, when the shutter curtain 1 is in a fully closed state or a pseudo fully closed state, the winding body 2 is restrained by the brake unit 20 in a non-rotating state. For this reason, even if an intruder tries to lift the shutter curtain 1 upward to open it, the shutter curtain 1 does not lift up, that is, the shutter curtain 1 does not open, and crime prevention is improved.

  Next, the slat 6 will be described with reference to FIGS. As shown in FIG. 5, a convex upper fitting portion 60 is formed on the upper side of the slat 6. A concave lower fitting portion 61 is formed on the lower side of the slat 6. The upper fitting portion 60 can be fitted to and detached from the lower fitting portion 61 of the slat 6 adjacent to the upper side. The lower fitting portion 61 can be fitted to and detached from the upper fitting portion 60 of the slat 6 adjacent to the lower side. FIG. 5C shows a fitted state of the slat 6 when the shutter curtain 1 moves in the opening or closing direction. When the shutter curtain 1 moves in the opening or closing direction, the linear connecting member 7 is in the extended state (flexible state) as described above, and the separation distance between the first links 71 of the linear connecting member 7 is as follows. It is said to be large. For this reason, the separation distance in the height direction (arrow H direction) between the slats 6 connected to the first link 71 is also large. As a result, when the shutter curtain 1 moves in the opening or closing direction, the lower fitting portion 61 and the upper fitting portion 60 of the slat 6 are adjacent to each other as shown in FIG. Or the degree of fitting is quite low. In this case, the adjacent slats 6 can rotate relative to each other in the direction of the arrow R3, so that the slats 6 can be wound around the outer peripheral surface 2p of the winding body 2.

  On the other hand, FIG. 5 (A) and FIG. 5 (B) show the slat 6 when the shutter curtain 1 is in a fully closed state. When the shutter curtain 1 is in the fully closed state, the linear connecting member 7 is in a contracted state (high rigidity state) as described above, and the distance between the first links 71 of the linear connecting member 7 is small. Has been. Accordingly, the slats 6 connected to the first link 71 approach each other. Therefore, as shown in FIGS. 5 (A) and 5 (B), the upper fitting portion 60 of the slat 6 adjacent to each other in the height direction (arrow H direction) is fitted to the lower fitting portion 61. As a result, the amount of fitting between the slats 6 increases. For this reason, relative rotation between adjacent slats 6 in the directions of arrows R3 and R4 is prevented. As a result, the rigidity at the boundary between adjacent slats 6 increases. As a result, the rigidity of the shutter curtain 1 is increased.

  In other words, when the linear connecting member 7 is in the extended extended position, the linear connecting member 7 has low rigidity and is flexible, so that the upper fitting portion 60 and the lower fitting of the slat 6 are fitted. The linear connecting member 7 can set the shutter curtain 1 so that the part 61 can rotate relative to the part 61. On the other hand, when the linear connecting member 7 is in the contracted position where the linear connecting member 7 is contracted, the linear connecting member 7 has high rigidity. Therefore, the upper fitting portion 60 and the lower fitting of the adjacent slats 6 are fitted together. The linear connecting member 7 can set the shutter curtain 1 so that relative rotation with the part 61 is restricted. Therefore, when the shutter curtain 1 is closed (see FIGS. 5A and 5B), the upper fitting portion 60 of the slat 6 and the lower fitting portion 61 of the slat 6 are fitted to each other. The rigidity of 1 is increased and crime prevention is enhanced. Further, according to the present embodiment, in the state where the shutter curtain 1 is rolled down, the crime prevention property for the boundary 63 between the slats 6 adjacent to each other in the height direction (arrow H direction) is further enhanced. That is, a step suppressing structure that suppresses a step between adjacent slats 6 in the height direction is set.

  As shown in FIG. 5C, a step is formed at the boundary between the upper fitting portion 60 and the lower fitting portion 61 of the slat 6 while the slat 6 of the shutter curtain 1 is moving up and down. Yes. However, when the shutter curtain 1 is closed, a step suppressing structure is employed. That is, as shown in FIG. 5B, while the upper fitting portion 60 and the lower fitting portion 61 of the slat 6 are fitted together, the upper fitting portion 60 and the lower fitting portion on the outdoor 12 side. The level | step difference in the boundary 63 between 61 is suppressed. Specifically, it is preferable that the step is 2 millimeters or less, 1 millimeter or less, and particularly substantially 0. Here, if a level difference is generated, the intruder uses the level difference to make use of the foreign object 100 such as a bar to use the upper side fitting part 60 and the lower side fitting part 61 of the slat 6. The boundary 63 may be forcibly opened. Therefore, according to the present embodiment, when the shutter curtain 1 is rolled down (closed state), as shown in FIG. 5B, the upper fitting portion 60 and the lower fitting portion of the slat 6 While the 61 is fitted to each other, the step at the boundary 63 between the upper fitting portion 60 and the lower fitting portion 61 is suppressed on the outdoor 12 side. Therefore, the intruder is prevented from prying open the boundary 63 between the upper fitting portion 60 and the lower fitting portion 61 with the foreign matter 100 such as a bar using the step, and the crime prevention property is excellent.

  In other words, in a state where the shutter curtain 1 is rolled down, as shown in FIGS. 5B and 6, the lower fitting portion 61 of the slat 6 has the engagement wall body 64 on the outdoor 12 side. It extends downward. A concave portion 65 extends upward on the upper fitting portion 60 of the slat 6 on the outdoor 12 side. Here, as shown in FIG. 6, the groove depth h <b> 1 of the concave portion 65 and the thickness t <b> 1 of the engaging wall body 64 are set to substantially the same value. As a result, when the upper fitting portion 60 and the lower fitting portion 61 of the slat 6 are fitted, the engagement wall body 64 and the concave portion 65 are engaged in a flat state as shown in FIG. ing. That is, in the state where the shutter curtain 1 is rolled down (closed state), the boundary between the exposed surface 60 a on the outdoor 12 side of the upper fitting portion 60 and the exposed surface 61 a on the outdoor 12 side of the lower fitting portion 61. 63 is a flat. Therefore, the intruder is prevented from prying open the boundary 63 between the upper fitting portion 60 and the lower fitting portion 61 with a foreign object 100 such as a bar using a step, and crime prevention against the intruder is enhanced. Yes.

  Furthermore, according to this embodiment, in order to further improve crime prevention, a clearance suppression structure that suppresses the clearance width of the boundary 63 between adjacent slats 6 is set. That is, in the state where the shutter curtain 1 is rolled down (closed state), as shown in FIGS. 5B and 6, the upper fitting portion 60 and the lower fitting portion 61 of the slat 6 are fitted to each other. However, the gap width at the boundary 63 between the upper fitting portion 60 and the lower fitting portion 61 on the outdoor 12 side is 1.5 millimeters or less, 1 millimeter or less, and particularly substantially zero. It is suppressed to become. In other words, the gap at the boundary 63 between the upper fitting portion 60 and the lower fitting portion 61 of the slat 6 is suppressed on the outdoor 12 side where the intruder exists. Therefore, it is suppressed that the intruder uses the gap to open the boundary 63 between the upper fitting portion 60 and the lower fitting portion 61 with the foreign matter 100 such as a bar, and the crime prevention property against the intruder is further enhanced. ing.

  Even if a minute gap is formed between the distal end portion 64c of the engagement wall body 64 and the proximal end portion 65c of the concave portion 65 by an intrusion action, the thickness t1 of the engagement wall body 64 is thin ( For example, 3 mm or less, 2 mm or less), the tip of the foreign matter 100 such as a bar is prevented from being caught on the tip 64c of the engagement wall 64. In this sense, crime prevention is further enhanced. Further, even if a foreign matter 100 such as a bar causes a minute gap to be formed between the distal end portion 64c of the engagement wall body 64 and the proximal end portion 65c of the concave portion 65 by an intruding action, Accordingly, as shown in FIGS. 5B and 7, an upright barrier 66 is formed on the outdoor 12 side of the upper fitting portion 60 of the slat 6. In the state in which the shutter curtain 1 is rolled down (closed state), the upright barrier 66 is in the vertical direction (arrow P direction) at the fitting portion between the upper fitting portion 60 and the lower fitting portion 61 of the slat 6. It is extended along. The upright barrier 66 is located inside the engagement wall body 64 and is covered with the engagement wall body 64. As a result, even if the intruder uses a foreign object 100 such as a bar to pry open the boundary 63 between the upper fitting portion 60 and the lower fitting portion 61 of the slat 6, FIG. 5 (B) and FIG. As shown, the upright barrier 66 acts as a barrier against intrusion of foreign matter 100 such as burls. Therefore, intrusion of a bar or the like is prevented by the upright barrier 66 of the slat 6.

  Furthermore, according to this embodiment, the fitting part rotation restraint part 67 is provided in the slat 6 in order to ensure crime prevention. The fitting part rotation restricting part 67 is a relative rotation between the upper fitting part 60 and the lower fitting part 61 of the slats 6 provided adjacent to each other in a state where the shutter curtain 1 is rolled down (closed state). It has a function to restrain. The fitting part rotation restricting part 67 is provided so that it can come into contact with the stopper part 68 in the hook claw-like stopper part 68 provided in the upper fitting part 60 of the slat 6 and the lower fitting part 61. And a stoppered portion 69 having a shape. When the shutter curtain 1 is closed and the foreign matter 100 is not pressed against the boundary 63 between the slats 6, as shown in FIG. 6, the stopper portion 68 and the stopper portion 69 are not in contact with each other. It is. When the shutter curtain 1 is closed, the stopper portion 68 and the stopper portion 69 are positioned away from the boundary 63 and above.

  In addition, when the shutter curtain 1 is in the closed state, foreign matter 100 such as bar from the outdoor 12 side excessively adds the boundary 63 between the upper fitting portion 60 and the lower fitting portion 61 in the intrusion direction (arrow X1 direction). As shown in FIG. 7, when the pressure is to be applied, the stopper portion 68 on the indoor 10 side comes into contact with and engages with the stopper portion 69 on the indoor 10 side. For this reason, the further relative rotation to the arrow R4 direction of the upper side fitting part 60 and the lower side fitting part 61 of the slat 6 is suppressed. Therefore, the rigidity in the fitting portion of the slat 6 is further increased. That is, the rigidity at the boundary 63 of the adjacent slat 6 is enhanced. Also in this sense, the rigidity of the shutter curtain 1 is increased and the crime prevention property is enhanced. In the middle of moving in the height direction (arrow H direction), such as when the slat 6 is wound around the winding body 2, as shown in FIG. 69 is separated from each other and brought into a non-contact state, and the adjacent slats 6 are rotatable relative to each other. That is, the fitting part rotation restricting part 67 allows relative rotation between the upper fitting part 60 and the lower fitting part 61.

  As shown in FIGS. 8 and 9, the vertical column 5 has a main guide passage 50 and a main rail portion 51 extending along the height direction (arrow H direction), a sub guide passage 53, And a sub rail portion 54 that forms a sub guide passage 53. 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 are communicated with each other by a communication passage 53x (see FIG. 10). While the shutter curtain 1 is being rolled down, as shown in FIG. 5C, the fitting amount between the upper fitting portion 60 and the lower fitting portion 61 is reduced. 68 and the to-be-stopped part 69 are separated and in 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. 8, closing urging 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, a slat rotation mechanism 8 (actuator switching mechanism) 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. Hereinafter, the slat rotation mechanism 8 will be described. As shown in FIG. 8, the end portion 6 f of the slat 6 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. The guided pin 59 may be rollable or may have a non-rolling structure. 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. 8) through which the guided pin 59 passes is provided in the upper part of the main guide passage 50. As shown in FIG. 8, the slat rotation mechanism 8 includes a cam 80 as an operating body having a cam guide surface 81 (guide surface), and an actuator 85 (operating body drive source) that operates the cam 80. Yes. 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. 8, 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 to which the actuator 85 is attached via a connecting pin 86e (connecting element) and a cam return spring 87 (retraction biasing member). 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 in the shutter curtain 1, the user switches the shutter curtain 1 wound around the winding body 2 when the shutter curtain 1 is rolled down in the downward direction (arrow H2 direction). 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. 8). Therefore, the cam 80 rotates against the cam return spring 87 in the engaging direction (in the direction of arrow E3 in FIG. 8) around the cam pin 88, and the cam guide surface 81 of the cam 80 protrudes to the engaging 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. 9, 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. 9). ) 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 around the pivot pin 6w in the ventilation promotion direction (the direction of the arrow F1 in FIG. 9).

  Accordingly, the slats 6 are turned sideways, and ventilation openings 6e (see FIG. 9) 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. Thus, even when the ventilating opening 6e is formed in the closed shutter curtain 1, the linear connecting member 7 is in a highly rigid state and the upper side of the slat 6 that has not been turned sideways. Since the fitting part 60 and the lower fitting part 61 are fitted to each other and the boundary 63 of the slat 6 is in a highly rigid state, it is advantageous in terms of crime prevention.

  According to this embodiment, since the guided pins 59 are formed on only a few of the upper slats 6, only the upper several slats 6 can be turned sideways, and only the upper few slats 6. Can be ventilated. However, the present invention is not limited to this, and the guided pin 59 may be provided only on the slat 6 located in the middle in the height direction. Furthermore, you may decide to provide only in the lower slat 6 of a height direction. Furthermore, the guided pins 59 may be provided on all the slats 6 so that all the slats 6 can be ventilated. In short, the slat 6 provided with the guided pin 59 can be turned sideways.

  By the way, when the shutter curtain is in a closed state, when the shutter curtain is pulled upward (in the direction of arrow H1) and operated to be lifted, the actuator is driven and the slat is rotated by the cam. A sideways ascent method is also conceivable. However, when this raising method is adopted, in order to make the slats beside, an operation of pulling the shutter curtain upward in the state where the shutter curtain is closed is essential. Here, pulling the shutter curtain upward is opposite to increasing the closing degree of the shutter curtain, and corresponds to operating the shutter curtain in the opening direction. Here, when the shutter curtain is in a closed state, in order to enhance crime prevention, the shutter curtain is completely closed (the linear connecting member is in a highly rigid state at the contracted position, or the slat is highly rigid. It is preferable that it is set to the state of For this reason, in a state where the shutter curtain is closed, the operation of raising the shutter curtain to form the opening between the slats causes the linear connecting member to be at least partially in the extended position, resulting in a low rigidity state. Because it is easy, it seems that it is not very good. In this regard, according to the present embodiment, when the slat 6 is rotated and turned sideways, as described above, the shutter curtain 1 wound around the winding body 2 is rolled down in the downward direction (arrow H2 direction). When the slat is rotated, the slat 6 is rotated laterally by the slat rotation mechanism 8 to form a ventilation opening 6e. For this reason, according to the present embodiment, when the shutter curtain 1 is closed, it is not necessary to operate the shutter curtain 1 in the direction in which the shutter curtain 1 is opened. .

  Further, when the slat 6 is rotated and turned sideways, the operation of pulling the shutter curtain 1 upward corresponds to applying an upward tensile force to the linear connecting member 7. According to the present embodiment, as described above, the linear connecting member 7 has a characteristic that can be switched between a flexible state and a highly rigid state. When an upward tensile force acts on the linear connecting member 7, the linear connecting member 7 is likely to be in the extended position, and thus is likely to be in a flexible state. For this reason, it is not a good measure to induce a reduction in rigidity of the linear connecting member 7 and to improve the crime prevention property by the shutter curtain 1. In this regard, according to the present embodiment, when the slat 6 is rotated and turned sideways, as described above, the shutter curtain 1 wound around the winding body 2 is unwound downward (arrow H2 direction). The method is adopted. For this reason, according to this embodiment, when the slat 6 is rotated and turned sideways, an upward tensile force is prevented from acting on the linear connecting member 7. Therefore, the linear connecting member 7 is prevented from reaching the extended position (corresponding to the flexible state). Therefore, according to this embodiment, even if it is a case where the slat 6 is rotated and it becomes sideways, the high rigidity of the linear connection member 7 is maintained, and high crime prevention property is maintained.

  Further, when the rolled shutter curtain 1 is wound around the winding body 2 by the motor 3, the user operates the switch to reversely move the motor 3. Thus, since the motor 3 is driven, the winding body 2 is rotated in the winding direction, and the linear connecting member 7 and the slat 6 are gradually wound around the outer peripheral surface 2p of the winding body 2. At this time, the guided pin 59 of the slat 6 that has been oriented sideways moves upward (in the direction of the arrow H1) along the sub-rail portion 54 along the sub-guide passage 53. When the guided pin 59 reaches the upper end portion 53 u of the auxiliary guide passage 53, the guided pin 59 is released from restraint by the auxiliary rail portion 54. The closing spring 89 always urges the slat 6 in a vertical direction so that the ventilation opening 6e disappears and is closed. For this reason, the slat 6 is automatically rotated in the direction in which the ventilation opening 6e disappears by the urging force of the closing spring 89 and returned to the vertical direction. At this time, since the actuator 85 is turned off, the cam 80 is returned to the retracted position MA by the urging force of the cam return spring 87 and is not engaged with the guided pin 59. Thus, the slat 6 returned to the vertical direction is gradually wound up on the outer peripheral surface 2p of the winding body 2.

  Further, according to the present embodiment, when the shutter curtain 1 that has been rolled down is manually wound up on the winding body 2 during an emergency or the like (for example, during a power failure), the brake action of the brake unit 20 is manually released. In this state, the shutter curtain 1 may be manually lifted by the user and wound up on the winding body 2. The actuator 85 and the guided pin 59 are preferably provided in both of the left and right directions of the slat 6, but may be provided in only one of them. In the above-described embodiment, the guided pin 59 attached to the slat 6 as a part of the slat 6 is engaged with the cam 80 to rotate the slat 6 sideways. The slat 6 itself may be directly engaged with the cam 80 and rotated. A cam 80 is provided as an operating body that engages with a part of the slat 6, but a link, an arm, a sphere, or the like may be used. The slat rotation mechanism has a function of switching the position of the operating body between an engaging position where the operating body engages with a part of the slat 6 and a retracted position where the operating body is retracted with respect to the slat. ,anything is fine. As in the other embodiment shown in FIG. 11, the second link 72 is eliminated, and the upper fitting pin 74 of the lower link 71 is inserted into the long hole 73 formed on the lower side of the upper first link 71. May be inserted movably. A rotation restricting portion 78 may be provided on the upper side of the lower link 71. Here, when the link 71 relatively swings, the lower end portion of the upper link 71 and the rotation restricting portion 78 of the lower link 71 are engaged. As a result, the rotation restricting portion 78 restricts rotation between the upper and lower links 71, 71, that is, position restriction, and secures rigidity. The present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist.
