JP 2001-271574 A

  According to the shutter device described above, when the shutter curtain is in a semi-closed state, the slat is maintained in the open posture. However, as the seat plate at the tip of the shutter curtain lands and the shutter curtain is fully closed, the slat in the open position is changed to the closed position. For this reason, when the shutter curtain is fully closed, the slats are in a closed posture, and no opening is formed between the slats, and there is a limit to lighting, ventilation, visual recognition, and the like.

  The present invention has been made in view of the above circumstances, and the slats constituting the shutter curtain can be rotated to the open posture, and even if the seat plate at the front end of the shutter curtain lands, It is an object of the present invention to provide a shutter device that can be maintained in an open posture and can satisfactorily maintain an opening that performs at least one function such as daylighting, ventilation, and visual recognition.

  According to the present invention, when the opening is not formed between the slats, when the shutter curtain moves in the closing direction, the operating body is set to the retracted position instead of the engaged position by the operating body switching mechanism. For this reason, the operating body does not engage with at least a part of the slats of the shutter curtain moving in the closing direction. For this reason, an opening is not formed between adjacent slats.

  In contrast, when the opening is formed between the slats, when the shutter curtain moves in the closing direction, 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 engaging position is engaged with at least a part of the slat of the shutter curtain that moves in the closing direction. As a result, the slat rotates to the open posture, and an opening is formed between adjacent slats. The opening described above performs at least one function such as lighting, ventilation, and visual recognition. Thus, according to the present invention, when the operating body is switched to the engaged position by the operating body switching mechanism, the slat can be rotated to the open posture. According to the present invention as described above, even if the seat plate at the tip of the shutter curtain lands, the slats constituting the shutter curtain can be maintained in the open posture, and the opening can be maintained.

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 line 2x, the shutter curtain 1 moves in the arrow H2 direction (shutter closing direction), and the seat plate 6x lands. 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 and moves in the arrow H1 direction (shutter opening direction).

  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 conceptual 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 shutter curtain 1 includes a plurality of slats 6 arranged in parallel in the opening / closing direction (arrow H direction) of the shutter curtain 1. The slat 6 includes a metal or resin slat main body 60 and a resin slat cap 62 fixed to both longitudinal ends of the slat main body 60. The slat cap 62 includes an adherend portion 63 attached to an end portion of the slat main body 60, and an axial protrusion portion 64 that protrudes axially from the adherend portion 63 in the outward direction (extending direction of the slat 6). ing. The axial protrusion 64 is connected to the linear connecting member 7. Here, among the plurality of slats 6, the upper predetermined number (for example, three) of slats 6 is set so as to be in an open posture. 3 and 4 show the main part of the slat 6. FIG. 3 shows a slat cap 62 of a slat 6o (o: open) that is set to be in an open position. As shown in FIG. 3, a first engaging portion 67 and a second engaging portion 68 are integrally formed on a resin slat cap 62 of the slat 6o using a resin material as a base material. The first engaging portion 67 is provided on the outer wall surface of the shaft-like protruding portion 64. The second engaging portion 68 is provided on the outer wall surface of the adherend portion 63 so as to protrude outward substantially parallel to the axial protrusion 64. The center of the first engaging portion 67 and the center of the second engaging portion 68 are formed with a distance ΔL (see FIG. 3) in the longitudinal direction (arrow L direction) of the slat 6.

  Of the plurality of slats 6 constituting the shutter curtain 1, slats 6s (s: shut) other than the slats 6o are set so as not to be in the open posture. This is to prevent the opening 6e from being formed more than necessary mainly for security reasons. FIG. 4 shows a main part of the slat cap 62 of the slat 6s set so as not to be in the open posture. As can be understood from the comparison between FIG. 3 and FIG. 4, the first engaging portion 67 and the second engaging portion 68 are not formed on the resin slat cap 62 of the slat 6 s.

  5 and 6 show the shutter curtain 1 in a state where the slat 6o that can be set to the open posture is not in the open posture but in the closed posture. As shown in FIG. 6, a convex upper fitting portion 60 u is formed on the upper side of the slat 6. A concave lower fitting portion 61d is formed on the lower side of the slat 6. The upper fitting portion 60u can be fitted to and detached from the lower fitting portion 61d of the slat 6 adjacent to the upper side. The lower fitting portion 61d can be fitted to and detached from the upper fitting portion 60u of the slat 6 adjacent to the lower side.

  As shown in FIG. 8, the vertical strut 5 is provided with a guide rail portion 53 that forms a first guide passage 51 and a second guide passage 52. The first guide passage 51, the second guide passage 52, and the guide rail portion 53 are extended along the height direction (arrow H direction).

  As shown in FIGS. 5 and 6, the actuator 8 is detachably attached to the upper end portion of the guide rail portion 53 of the vertical column 5 that is a part of the base portion. The actuator 8 includes a guide rail cap member 80 fixed to the upper end portion of the guide rail portion 53 so as to close the upper end opening 53f of the guide rail portion 53 of the vertical column 5 so as to become a part of the base portion, and a guide rail cap member Resin lid member 81 attached to 80, hard resin or metal actuator 83 attached to lid member 81, and actuator switching mechanism 84 attached to guide rail cap member 80 (see FIG. 5) And. The fitting portion 80 a that forms the lower portion of the guide rail cap member 80 is fitted in the upper end opening 53 f at the uppermost end of the guide rail portion 53 of the vertical column 5. The fitting portion 80a is attached to the guide rail portion 53 with a fixture 80d (see FIG. 10).

  According to the present embodiment, as shown in FIGS. 7 to 9, the operating body 83 is slidably supported by the lid member 81 of the actuator 8 so as to be movable in the directions of arrows E1 and E2. That is, as shown in FIG. 7, the lid member 81 includes a moving path 81b for moving the operating body 83 in the directions of arrows E1 and E2 (linear movement direction, a direction orthogonal to the opening / closing direction of the shutter curtain 1), and the operating body 83. And a plate-like spring portion 82 that faces and regulates the upper side surface 83u. Thus, the operating member 83 is movable between the engaging position A and the retracted position B along the direction intersecting the opening / closing direction (arrow H direction) of the shutter curtain 1 so as to be movable. 81. A base end portion 82 a of the spring portion 82 is connected to the lid member 81 so as to be swingable. A tip end portion 82c forming a protrusion shape of the spring portion 82 is a free end shape, faces the upper surface 83u which is a part of the operating body 83, and maintains the posture of the operating body 83 at a fixed position (substantially horizontal position). It has a function. The lid member 81 has a long hole 81x and a hole 81y.

  Although the operating body 83 is regulated by the spring portion 82, it can be displaced in the avoidance direction (the direction of arrow F <b> 1 shown in FIG. 7) against the biasing force of the spring portion 82. Even if the position of the operating body 83 is displaced in this way, the operating body 83 can return to the return direction (in the direction of arrow F2 shown in FIG. 7) by the biasing force of the spring portion 82 and return to the home position.

  8 and 9 show sectional views of the guide rail portion 53 in the direction perpendicular to the axis. As shown in FIGS. 8 and 9, the operating body 83 has an operating protrusion 83 e that protrudes toward the axial protrusion 64 of the slat 6. FIG. 8 shows a state where the surface 83eo of the operating projection 83e of the operating body 83 is separated from the outer wall surface 53e of the guide rail portion 53 by a distance S2 and switched to the retracted position B. In this case, as shown in FIG. 8, in the longitudinal direction of the slat 6 (in the direction of the arrow L), the operating projection 83e of the operating body 83 and the first engaging portion 67 of the slat 6 are separated by a dimension LW. As a result, even if the slat 6 is lowered, the first engaging portion 67 of the slat 6 and the operating projection 83e of the operating body 83 cannot be engaged (contacted).

  On the other hand, FIG. 9 shows a state in which the surface 83eo of the operating projection 83e of the operating body 83 is separated from the outer wall surface 53e of the guide rail portion 53 by the distance S1 and switched to the engaging position A. In this case, as shown in FIG. 9, in the longitudinal direction (arrow L direction) of the slat 6, the first engaging portion 67 of the slat 6 and the operating projection 83e of the operating body 83 can face each other. The operating protrusion 83e of the operating body 83 and the first engaging portion 67 can be engaged (contacted).

  As shown in FIG. 5, the operating body switching mechanism 84 switches the operating body 83 between the engagement position A and the retracted position B, and is mounted on the guide rail cap member 80 held at the upper end of the guide rail section 53. Has been. The operating body switching mechanism 84 includes a drive source 85, a link-like swing body 86 that is swung by the drive source 85, and a bias coil spring that constantly biases the swing body 86 toward the retracted position B. A member 86h. Here, the biasing member 86h constantly biases the swinging body 86 toward the retracted position B in the retracting direction (arrow E1 direction). For this reason, even if the drive source 85 breaks down, the oscillating body 86 is not in the engagement position A (the position where the slat 6o is in the open position) but in the retracted position B (the slat 6o is in the open position). Is not maintained). Therefore, it is possible to prevent the slat 6o from being erroneously opened, which is preferable for crime prevention.

  The drive source 85 is held by the guide rail cap member 80 of the actuator 8 and can advance in one direction (K1 direction, upward direction) and retreat in the other direction (K2 direction, downward direction) with the excitation solenoid 85a. And a movable plunger 85c. The drive source 85 has an exciting solenoid, but it may be a motor, a pneumatic cylinder, or a hydraulic cylinder, and may be anything that can move the operating body 83 between the engagement position A and the retracted position B.

  The swinging body 86 is pivotally supported by a fixture 87 serving as a swing center in the guide rail cap member 80 of the actuator 8 so as to be swingable in one direction (arrow D1 direction) and the other direction (arrow D2 direction). Has been. The swinging body 86 and the movable plunger 85c are connected to each other by a pin-shaped first connecting tool 88 so as to be swingable. Specifically, the long hole 86c of the rocking body 86 and the first connector 88 of the movable plunger 85c are fitted. The distal end portion 86e of the swinging body 86 and the base end portion 83k of the actuating body 83 are connected by a pin-like second connecting tool 89 so as to be swingable.

  Here, when the drive source 85 is driven in one direction (engagement direction) and the movable plunger 85c is moved in the engagement direction (arrow K1 direction), the oscillator 86 moves around the fixture 87 in the engagement direction. Then, the operating projection 83e of the operating body 83 moves in the engaging direction (arrow E1 direction) and becomes the engaging position A (see FIG. 10). On the other hand, when the drive source 85 is driven in the other direction (retracting direction) and the movable plunger 85c is moved in the retracting direction (arrow K2 direction), the swinging body 86 is retracted around the fixture 87 (arrow). D2 direction), and as a result, the operating projection 83e of the operating body 83 moves in the retracting direction (arrow E2 direction) to the retracted position B.

  Next, a case where the shutter curtain 1 is closed will be described. In this case, if the drive source 85 of the actuator 8 is off, as shown in FIG. 5, the movable plunger 85c of the drive source 85 is moved in the retracting direction (arrow K2 direction), and the swinging body 86 is energized. It is urged by the member 86h and swings in the retreat direction (arrow D2 direction) around the rotation center (mounting tool 87) of the swinging body 86. As a result, the operating body 83 moves in the retracting direction (arrow E2 direction) and is retracted to the retracting position B (see FIGS. 5 and 8). In this state, when the motor 3 operates in the unwinding direction and the winding body 2 rotates in the unwinding direction, the shutter curtain 1 is unwound from the winding body 2, and the shutter closing direction (arrow H2 direction, downward direction). Move to. At this time, as described above, since the drive source 85 of the actuator 8 is OFF (disconnection), the operating projection 83e of the operating body 83 is switched to the retracted position B by the urging force of the urging member 86h ( (See FIGS. 5, 6, and 8). For this reason, the passage 57 is secured. Therefore, even if the slat 6 moves downward, the first engaging portion 67 of the slat 6 can pass through the passage 57 without hindrance. Therefore, the operating protrusion 83e of the operating body 83 and the first engaging portion 67 of the slat 6 are different. The distances LW (see FIG. 8) are separated and do not engage (contact) each other. Accordingly, the slat 6o does not rotate to the open posture but is lowered downward in the closed posture. Therefore, when the shutter curtain 1 is closed, none of the slats 6o is rotated to the open posture, and no opening 6e is formed between the adjacent slats 6o (see FIG. 6). When the slat 6 descends in the direction of the arrow H2 (downward), the axial protrusion 64 of the slat cap 62 of the slat 6 descends in the first guide passage 51 of the guide rail portion 53 (see FIG. 8).

  Next, the case where the slat 6o is set to the open posture when the shutter curtain 1 is closed will be described. In this case, the drive source 85 of the actuator 8 is turned on. Then, the movable plunger 85c of the drive source 85 is moved in the engagement direction (arrow K1 direction), the swinging body 86 is moved in the engagement direction (arrow D1 direction), and as a result, the operation body 83 is operated. The protrusion 83e moves in the engagement direction (arrow E1 direction). As a result, the operating protrusion 83e of the operating body 83 is switched to the engagement position A (see FIGS. 10 and 9). Thus, when the operating body 83 is switched to the engagement position A, when the motor 3 operates in the unwinding direction and the winding body 2 rotates in the unwinding direction, the shutter curtain 1 is moved from the winding body 2. Unwinding and moving in the direction of arrow H2 (closed direction, downward). At this time, as described above, the operating protrusion 83e of the operating body 83 is located at the engagement position A, and closes the passage 57. Therefore, as can be understood from FIGS. 10 and 11, the first engaging portion 67 of the slat 6 o is engaged (contacted) with the operating protrusion 83 e of the operating body 83. Accordingly, the slat 6o rotates around the axial protrusion 64 in the opening posture direction (the direction of the arrow M1 shown in FIG. 11). Thus, the 1st engaging part 67 can function as a rotation starting point part used as the starting point which rotates the slat 6o to an open posture direction. Therefore, the slat 6 is maintained in the open posture and is lowered downward in the open posture. Therefore, when closing the shutter curtain 1, the slat 6o in which the first engaging portion 67 is formed rotates in the opening posture direction (arrow M1 direction). Therefore, as shown in FIGS. 10 and 11, an opening 6e is formed between adjacent slats 6o. The opening 6e can function for ventilation, lighting, and visual recognition. Thus, when the slat 6o rotates in the direction of the arrow M1 and assumes the open posture, the second engagement portion 68 remains in the second guide passage 52 of the guide rail portion 53 as shown in FIG. To descend. In this state, the slat 6o is applied with a biasing force in a direction (arrow M2 direction) in which the slat is in a closed posture by a spring (not shown). Since it hits 52c (see FIG. 11), the slat 6o cannot rotate in the closed posture (arrow M2 direction). For this reason, when the shutter curtain 1 is closed, the slat 6o can be maintained in the open posture. Thus, the 2nd engaging part 68 can function as an open posture maintenance part which maintains the slat 6o in an open posture.

  However, even when the operating protrusion 83e of the operating body 83 exists at the engagement position A, the non-open slat 6s does not include the first engaging portion 67, and therefore cannot engage with the operating protrusion 83e. The slats 6s cannot rotate to the open posture and move downward (in the direction of the arrow H2) in the closed posture. Therefore, in the non-open slat 6s, the opening 6e is not formed between the adjacent slats 6s. Therefore, according to the present embodiment, the slat 6 corresponding to the position where the opening 6e is desired to be formed may be the slat 6o having both the first engaging portion 67 and the second engaging portion 68. The slat 6 corresponding to the position where the opening 6e is not desired to be formed may be the slat 6s (without the first engaging portion 67 and the second engaging portion 68). In this way, any of the plurality of slats 6 can be used as the slat 6o. In general, in consideration of crime prevention or the like, the first engaging portion 67 and the second engaging portion 68 can be formed on the upper several of the plurality of slats 6 to form the slat 6o. In this case, even if the slat 6o rotates in the opening posture direction and the second engagement portion 68 frictionally slides on the wall surface 52c of the second guide passage 52, the friction sliding distance is short and clear. 2 Wear of the engaging portion 68 is suppressed. The first engaging portion 67 and / or the second engaging portion 68 may be formed of the same material as that of the slat cap 62, or may be more frictional than the resin constituting the slat cap 62. Further, it may be formed of a strong resin (for example, engineer plastic), and in some cases, a metal such as an aluminum alloy may be used. Of course, the first engaging portion 67 and the second engaging portion 68 may be formed for all the slats 6 to form the slats 6o.

  Next, a case where the shutter curtain 1 in the closed state is moved in the opening direction (arrow H1 direction) will be described. In this case, the winding body 2 is rotated around the rotation center line 2x by the motor 3 in the winding direction. Then, the linear connecting member 7 below the winding body 2 moves upward (in the direction of arrow H1) and is gradually wound around the outer peripheral surface of the winding body 2. In this case, the drive source 85 for setting the slat 6o to the open posture is off, and the operating projection 83e of the operating body 83 is retracted to the retracted position B. Thus, when the operating projection 83e of the operating body 83 is retracted to the retracted position B, when the slat 6o moves upward (in the direction of the arrow H1), the second engaging portion 68 that moves upward together with the slat 6o operates. There is a risk of contact with the operating projection 83e of the body 83 and interference. In this case, there is a possibility that the slat 6o cannot move upward. Therefore, according to the present embodiment, as shown in FIG. 7, the operating body 83 is supported by the lid member 81 of the actuator 8 so as to be displaceable in the avoiding direction (arrow F1 direction, upward) so as to avoid the interference. Yes. That is, as described above, the lid member 81 includes the moving passage 81b that moves the operating body 83 in the directions of arrows E1 and E2, and the plate-like spring that supports the operating body 83 so as to be displaceable in the avoidance direction (arrow F1 direction). Part 82. Therefore, when the slat 6o moves upward (in the direction of the arrow H1) together with the second engagement portion 68, the second engagement portion 68 of the slat 6o that moves upward moves the lower surface 83d (FIG. 7) of the operation projection 83e of the operating body 83. The operating body 83 can be displaced in the avoidance direction (the direction of the arrow F1) around the second connector 89. As a result, the slat 6o is always urged in the closed posture direction (arrow M2 direction shown in FIG. 11) by a spring (not shown), so the slat 6o is automatically urged in the closed posture direction (arrow M2 direction). Therefore, the second engaging portion 68 of the slat 6o can escape from the interference. As a result, the slat 6o can be wound around the winding body 2 in a closed state.

  As described above, according to the present embodiment, the opening 6e can be formed by rotating the slat 6o constituting the shutter curtain 1 to the open posture. Further, according to the present embodiment, the operating projection 83e of the operating body 83 is located between the engagement position A and the retracted position B in a direction (arrow E1) that intersects the opening / closing direction (arrow H direction) of the shutter curtain 1. , E2 direction). For this reason, the moving distance between the engaging position A and the retracted position B can be shortened for the operating protrusion 83e of the operating body 83. Therefore, the switching time between the engagement position A and the retracted position B can be completed in a short time.

  In addition, according to the present embodiment, the actuator 8 including the operating body 83 and the operating body switching mechanism 84 is attached to the upper end opening 53 f of the guide rail portion 53 of the vertical column 5, whereby the guide rail portion 53 of the vertical column 5. It is provided at the upper end of (base). For this reason, it is not necessary to form an unnecessary mounting opening in the guide rail portion 53 of the vertical column 5, the assembling property of the actuator 8 can be improved, and the strength of the guide rail portion 53 can be ensured.

  Further, according to the present embodiment, the first engaging portion 67 that makes the slat 6o open and the second engaging portion 68 that maintains the slat 6o in the open posture are integrally formed on the resin slat cap 62 of the slat 6o. Has been. For this reason, an increase in the number of parts can be suppressed. Further, even when the positions, shapes, sizes, etc. of the first engaging portion 67 and the second engaging portion 68 are changed, the first engaging portion 67 and the second engaging portion 68 are made of resin slat caps. Since it is integrally formed at 62, the positions, shapes, sizes, etc. of the first engaging portion 67 and the second engaging portion 68 can be easily changed.

  Further, the moving direction of the operating body 83 is the directions of arrows E1 and E2, and along the longitudinal direction of the slat 6 (the direction of arrow L), the moving direction of the movable plunger 85c of the drive source 85 is the vertical direction. For this reason, it is suppressed that the size of the shutter device increases laterally outward.

  By the way, when the slat 6 moves in the closing direction (arrow H2 direction), when the drive source 85 is off, the operating body 83 is set to the retracted position B (a position where the slat 6 is not in the open posture). Nevertheless, depending on conditions or the like, the slat 6 may be affected by frictional sliding between the slat 6 and the vertical support 5 and the slat 6 may be erroneously opened toward the open posture.

  In this regard, according to the present embodiment, although the driving source 85 is off and the operating body 83 is set to the retracted position B (a position where the slat 6 is not in the open position), frictional sliding or the like is performed. When the slat 6 is erroneously opened due to the influence, a depressing surface 830 (see FIG. 6) is formed on the operating body 83 as a deterring portion that deters the erroneous opening of the slat 6. The restraining surface 830 contacts the slat 6 to prevent the slat 6 from being in an open posture due to an error. Specifically, as can be understood from FIG. 6, the restraining surface 830 contacts the second engagement portion 68 of the slat 6 to prevent the slat 6 from being erroneously in the open posture direction (arrow M1 direction). be able to. Since the engaging body 83 is made of resin, the restraining surface 830 can be easily formed by integral molding, and an increase in the number of parts is prevented.

According to the present embodiment, when the shutter curtain 1 is closed, the drive source 85 of the actuator 8 is turned on to bring the slat 6o into the open posture, and the actuator 8 is driven when the slat 6o is put into the closed posture. Although the power source 85 is turned off, the present invention is not limited to this. In some cases, the drive source 85 of the actuator 8 is turned off to bring the slat 6o into the open posture, and the actuator when the slat 6o is put into the closed posture. Eight drive sources 85 may be turned on.

  According to the present embodiment, the first engaging portion 67 and the second engaging portion 68 are formed in each of the slat caps 62 at both ends of the slat body 60, and the first guide is provided in each of the two vertical struts 5. Although the passage 51 and the second guide passage 52 are formed, the actuator 8 for setting the slat 6o to the open posture is mounted on only one of the two vertical struts 5 to reduce the cost. Yes. However, the actuator 8 may be mounted on both of the two vertical columns 5.

  According to the present embodiment, the first engaging portion 67 and the second engaging portion 68 are formed in each of the slat caps 62 at both ends of the slat main body 60. However, when the length of the slat 6 is short, etc. The first engaging portion 67 and the second engaging portion 68 may be formed on the slat cap 62 at one end of the slat main body 60. In the present embodiment, the first engaging portion 67 of the slat cap 62 attached to the slat 6 as a part of the slat 6 is engaged with the operating body 83 so that the slat 6 is rotated to the open posture. However, the present invention is not limited to this, and the slat body 60 itself may be directly engaged with the operating projection 83e of the operating body 83 to rotate the slat 6o to the open posture.

(Embodiment 2)
FIG. 12 shows a second embodiment. This embodiment has basically the same configuration and the same function and effect as the first embodiment. In the operating body switching mechanism 84 according to the present embodiment, as shown in FIG. 12, the movable plunger 85 c of the drive source 85 is connected to the operating body 83 without the oscillating body 86 according to the first embodiment. . The moving direction of the movable plunger 85c of the drive source 85 is a horizontal direction (directions of arrows E1, E2 and a direction intersecting with the opening / closing direction of the shutter curtain 1). In this case, the movable plunger 85c of the drive source 85 can be directly connected to the operating body 83, and the rocking body 86 can be eliminated. Also in the present embodiment, when the movable plunger 85c of the drive source 85 moves in the arrow E1 direction, the operating body 83 moves in the arrow E1 direction. When the movable plunger 85c of the drive source 85 moves in the arrow K2 direction, the operating body 83 moves in the arrow E2 direction.

(Embodiment 3)
13 to 15 show the third embodiment. Since this embodiment basically has the same configuration and the same function and effect as those of the first embodiment, FIGS. 1 to 11 can be applied mutatis mutandis. In the present embodiment, as shown in FIG. 13, the linear connecting member 7 is guided from the expansion guide portion 51p to the first guide passage 51 of the guide rail portion 53, and has a vertically long first shape. The link 71, the second link 72 having a vertically long shape that pivotally supports the first link 71 that is adjacent in the height direction, and the height direction provided at the upper and lower ends of the first link 71, respectively. It has a long hole 73 extending in the direction of arrow H and a protruding fitting pin 74 (fitting body) provided in the second link 72. As shown in FIG. 13, 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 from the outer peripheral surface 2p of the winding body 2 in the separating direction (in the direction of arrow HB shown in FIG. 13) 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, 7 m of intermediate parts of the 1st volt | bolt 75 and the 2nd volt | bolt 76 among the linear connection members 7 cannot detach | leave from 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. 13, when the winding body 2 is rotated around the rotation center line 2x by the motor 3 in the winding direction (arrow A1 direction), the linear connecting member 7 below the winding body 2 is moved upward ( It moves in the direction of arrow H1) and is gradually wound around the outer peripheral surface 2p of the wound body 2. On the other hand, when the motor 3 moves backward and the winding body 2 rotates in the unwinding direction (arrow A2 direction) around the rotation center line 2x, the linear connecting member 7 moves downward (arrow H2). Direction) and is unwound from the outer peripheral surface 2p of the winding body 2. 14A, 14B, and 14C show the operation of the linear connecting member 7. FIG. As shown in FIG. 14, 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. 14 (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 (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. 14B, 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. 14C, 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. 14A, 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. 14A, 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. 14A, 14 </ b> B, and 14 </ 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, in the contracted position, as shown in FIG. 14A, 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 a 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. 14B shows a state where 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. 14B, 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. 13), 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. 14C).

  In FIG. 13, 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. 13, 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 point portion 77 of the linear connecting member 7, that is, the portion immediately below the first bolt 75 is set to the virtual horizontal line HA passing through the rotation center line 2 x of the winding body 2 in the horizontal direction or to the virtual horizontal line HA. The number of the first links 71 and the slats 6 is set so as to be disposed below. According to this embodiment, as shown in FIG. 13, 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. 14). (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 the fully closed state or the pseudo fully closed state, the winding body 2 is restrained to the non-rotating state by the brake unit 20. 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.

  The slat 6 according to the present embodiment will be described with reference to FIG. As shown in FIGS. 15A, 15 </ b> B, and 15 </ b> C, a convex upper fitting portion 60 u is formed on the upper side of the slat 6. A concave lower fitting portion 61d is formed on the lower side of the slat 6. The upper fitting portion 60u can be fitted to and detached from the lower fitting portion 61d of the slat 6 adjacent to the upper side. The lower fitting portion 61d can be fitted to and detached from the upper fitting portion 60u of the slat 6 adjacent to the lower side. FIG. 15C shows the 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, as shown in FIG. 15C, the lower fitting portion 61d and the upper fitting portion 60u of the slat 6 are provided adjacent to each other. 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. 15A and FIG. 15B 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. Accordingly, as shown in FIGS. 15A and 15B, the upper fitting portion 60u and the lower fitting portion 61d of the slat 6 that are adjacent to each other in the height direction (arrow H direction) are fitted to each other. And 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 60u of the slat 6 and the lower fitting are provided. The linear connecting member 7 can set the shutter curtain 1 so that the part 61d can rotate relative to the part 61d. 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 60u of the adjacent slat 6 and the lower fitting are provided. The linear connecting member 7 can set the shutter curtain 1 so that relative rotation with the part 61d is restricted. Therefore, when the shutter curtain 1 is closed (see FIGS. 15A and 15B), the upper fitting portion 60u of the slat 6 and the lower fitting portion 61d of the slat 6 are fitted, so the shutter curtain The rigidity of 1 is increased and crime prevention is enhanced. Furthermore, according to the present embodiment, in the state where the shutter curtain 1 is rolled down, the crime prevention property for the boundary 63x 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. 15C, a step is formed at the boundary between the upper fitting portion 60u and the lower fitting portion 61d 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. 15B, while the upper fitting portion 60u and the lower fitting portion 61d of the slat 6 are fitted to each other, the upper fitting portion 60u and the lower fitting portion on the outdoor 12 side. The level difference at the boundary 63x with respect to 61d 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 60u and the lower side fitting part 61d of the slat 6. There is a risk of forcibly opening the boundary 63x.

  Thus, according to the present embodiment, when the shutter curtain 1 is rolled down (closed state), as shown in FIG. 15B, the upper fitting portion 60u and the lower fitting portion of the slat 6 are arranged. While the 61d is fitted to each other, the step at the boundary 63x between the upper fitting portion 60u and the lower fitting portion 61d is suppressed on the outdoor 12 side. Therefore, the intruder is prevented from opening the boundary 63x between the upper fitting portion 60u and the lower fitting portion 61d with the foreign matter 100 such as a bar using the step, and the crime prevention property is excellent.

  In other words, in the state where the shutter curtain 1 is rolled down, as shown in FIG. 15B, the engaging wall body 64x extends downward on the lower fitting portion 61d of the slat 6 on the outdoor 12 side. It is installed. A concave portion 65x extends upward on the upper fitting portion 60u of the slat 6 on the outdoor 12 side. When the upper fitting portion 60u and the lower fitting portion 61d of the slat 6 are fitted, as shown in FIG. 15A, the engagement wall body 64x and the recessed portion 65x are engaged in a flat state. ing. That is, in the state where the shutter curtain 1 is rolled down (closed state), the boundary between the exposed surface 60a on the outdoor 12 side of the upper fitting portion 60u and the exposed surface 61a on the outdoor 12 side of the lower fitting portion 61d. 63x is flat. Therefore, the intruder is prevented from prying open the boundary 63x between the upper fitting portion 60u and the lower fitting portion 61d with the foreign matter 100 such as a bar by using the step, and the security against the intruder is improved. Yes.

  Furthermore, according to this embodiment, the fitting part rotation restraint part 67x is provided in the slat 6 in order to ensure security. The fitting portion rotation restricting portion 67x is a relative rotation between the upper fitting portion 60u and the lower fitting portion 61d of the slats 6 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 67x is provided so that it can come into contact with the stopper part 68x in the hook claw-like stopper part 68x provided in the upper fitting part 60u of the slat 6 and the lower fitting part 61d. And a stoppered portion 69x having a shape. In a state where the shutter curtain 1 is closed and the foreign matter 100 is not pressed against the boundary 63x between the slats 6, as shown in FIG. 14, the stopper portion 68x and the stopper portion 69x are not in contact with each other. It is. When the shutter curtain 1 is closed, the stopper portion 68x and the stopper portion 69x are located away from the boundary 63x.

However, the actuator 8 is not limited to this and may be positioned below the upper end portion of the vertical column 5. As in the embodiment, the second link 72 is abolished, and the upper fitting pin 74 of the lower link 71 is movably inserted into the long hole 73 formed on the lower side of the upper first link 71. May be. 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.
