  Hereinafter, Embodiment 1 of the present invention will be described in detail with reference to FIGS. 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.

  As shown in FIG. 1, the shutter device includes a shutter curtain 1 formed by arranging a plurality of slats 6 along the height direction (arrow H direction), and a winding body 2 that winds up the shutter curtain 1. A motor 3 that is a drive mechanism for rotating the winding body 2, a horizontal frame 4 that constitutes a part of a base that rotatably holds the winding body 2, and sides of the shutter curtain 1. And two vertical struts 5 constituting a part of the base. A switch (not shown) for controlling the motor 3 is provided. When the motor 3 is driven by the switch and the winder 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 6xo 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 shutter curtain 1 is formed by a plurality of slats 6 and a chain-like linear connecting member 7 that functions as a suspension member that suspends both ends of the slats 6 in the longitudinal direction (L direction). The slat 6 is extended along the longitudinal direction (L direction) between the two vertical struts 5. 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 connecting members 7 (suspension members) are respectively provided on the left and right sides of the shutter curtain 1.

  The linear connecting member 7 connects end portions in the length direction of the slats 6 adjacent to each other in the height direction (arrow H direction) of the shutter device, and expands and contracts along the height direction (arrow H direction). It is possible. 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 slat main body 60 made of metal or resin, and a resin slat cap 62 fitted to both ends of the slat main body 60 in the longitudinal direction. The slat cap 62 has an attached portion 63 attached to an end portion of the slat main body 60, and an axial shape protruding outward from the attached portion 63 in the axial direction along the outward direction (longitudinal direction of the slat 6). And a protrusion 64. The axial protrusion 64 is connected to the linear connecting member 7. Here, among the plurality of slats 6, a predetermined number (for example, three) of slats 6 on the uppermost side or the upper side are set so as to be in an open posture as rotating slats 6o.

  As shown in FIG. 5, the linear connecting member 7 rotates a first link 71 having a vertically long shape having ends 71 a and 71 c and a first link 71 adjacent in the height direction via a pivotal support 74. It is formed by alternately connecting the second links 72 having a vertically long shape that is pivotally supported. The linear connecting member 7 has a long hole 73 provided at 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). The first link 71 is pivotally connected to the end surface of the axial protrusion 64 of the slat 6 integrally with an end portion in the longitudinal direction of the slat 6 by a pivot pin 6w (connection element). Accordingly, the slat 6 is rotatable with respect to the first link 71 around the pivot pin 6w and the shaft core 64p of the shaft-like protrusion 64. Here, according to the present embodiment, a spring 650 (torsion coil spring, see FIG. 5) that exerts an urging force that closes the window opening 6 e is provided on all the slats 6, and the slats of the first link 71 and the slat 6. Provided between the cap 62 and the axial protrusion 64. In a normal state, the slat 6 is urged in the closing direction about the axis 64p by the urging force of the spring 650. For this reason, the stopper portion 600 formed on the shaft-like protruding portion 64 of the slat 6 is engaged with the abutted surface 711 of the stopper portion 710 of the first link 71, and as a result, All the slats 6 are maintained in the closed position.

  FIG. 3 relates to a comparative example and represents a cross section showing the thickness of the slat 6. As shown in FIG. 3, 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 fitting 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. When the shutter curtain 1 is in the fully closed state, the upper fitting portion 60u and the lower fitting portion 61d of the slats 6 adjacent to each other in the height direction (arrow H direction) are fitted to each other, and the slats 6 The amount of fitting has increased (not shown). 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 and the crime prevention property is improved.

  According to the present embodiment (FIG. 4), the slat opening mechanism 84 is provided as in the comparative example (FIG. 3). The slat opening mechanism 84 is a mechanism for rotating and opening a predetermined slat 6 so as to form a window opening 6e between the slats 6 when the shutter curtain 1 moves in the closing direction (arrow H2 direction) and performs a closing operation. It is. Here, the slat 6 to be rotated among the plurality of slats 6 is defined as a rotating slat 6o. The number of rotating slats 6o for opening the window openings 6e is preferably limited to several in terms of security in one shutter device. However, it is not limited to this. Here, among the plurality of slats 6, a predetermined number of the uppermost shutter shutter 1 is a rotatable slat that can rotate around the shaft core 64 p of the shaft-like protrusion 64 so that the window opening 6 e can be formed. 6o.

  FIG. 3 according to the comparative example shows a state in which the window slat 6o is formed by rotating the rotating slat 6o while the shutter curtain 1 moves in the closing direction (arrow H2 direction). When the shutter curtain 1 moves in the closing direction (arrow H2 direction), the linear connecting member 7 is in a flexible state. When the shutter curtain 1 is moving in the closing direction, as shown in FIG. 3, the lower fitting portion 61d and the upper fitting portion 60u adjacent to each other in the direction of the arrow H2 are fitted to each other. Or the degree of fitting is quite low. As a result, the rigidity of the shutter curtain 1 is low. Therefore, when the shutter curtain 1 is moved in the closing direction, the slat 6 constituting the shutter curtain 1 can be unwound from the winding body 2 together with the linear connecting member 7, and further, the shutter curtain 1 is opened in the opening direction (arrow H1). When moving in the direction), the slat 6 can be wound around the winding body 2 together with the linear connecting member 7.

  Further, among the slats 6, a non-rotating type slat that is adjacent to the rotating slat 6o and does not rotate so as to form the window opening 6e is defined as an adjacent slat 6sc. Of the slats 6, of the rotating slats 6 o that rotate so as to form the window opening 6 e, a single slat that exists immediately below the lowermost rotating slat 6 o is defined as an adjacent slat 6 sc. . Here, when the plurality of rotating slats 6o are collectively arranged in the height direction, one of the plurality of rotating slats 6o is located directly below the lowest rotating slat 6o. The slat corresponds to the adjacent slat 6sc. Alternatively, when every other rotating slat 6o is present, a non-rotating type slat that exists immediately below each rotating slat 6o corresponds to the adjacent slat 6sc. When the slat directly below a certain rotation slat 6o is the rotation slat 6o, the rotation slat 6o directly below is rotated to form the window opening 6e. The problem is suppressed.

  In the comparative example, as shown in FIG. 3, when the rotation slat 6o rotates in the rotation direction (in the direction of the arrow RK) about the axis 64p of the shaft-like protruding portion 64, the rotation slat 6o A trajectory that the end 61de of the lower fitting portion 61d can rotate is shown as a rotation trajectory RW. When the shutter device is manufactured, even if the end 61de of the lower fitting portion 61d of the rotating slat 6o is rotated about the axis 64p along the rotation locus RW so as to form the window opening 6e, A gap D1 (see FIG. 3) is set between the end portion 61de of the lower fitting portion 61d of the moving slat 6o and the end portion 60ue of the upper fitting portion 60u of the adjacent slat 6sc. As a result of the presence of the gap D1, the end 61de of the lower fitting portion 61d of the rotating slat 6o and the adjacent slat 6sc can be connected to each other even if the rotating slat 6o rotates along the rotation locus RW. It is set so as not to interfere with the end portion 60ue of the upper fitting portion 60u, that is, so as not to come into contact with each other and rub. In this case, as can be understood from FIG. 3, the end portion 60 ue of the upper fitting portion 60 u of the adjacent slat 6 sc is on the indoor 10 side with respect to the virtual line HP that connects the shaft cores 64 p of the shaft-like protruding portion 64. The end portion 60ue of the upper fitting portion 60u of the rotating slat 6o protrudes by the same amount, that is, ΔW1.

  By the way, there is a possibility that the above-described gap D1 may disappear due to the influence of the shutter device over time, dimensional tolerances, and the like. In this case, in the comparative example shown in FIG. 3, when the end 61de of the lower fitting portion 61d of the rotation slat 6o rotates along the rotation locus RW so as to form the window opening 6e, the portion XA The end portion 61de of the lower fitting portion 61d of the rotating slat 6o and the end portion 60ue of the upper fitting portion 60u of the adjacent slat 6sc may interfere with each other and rub against each other. In particular, when the length of the slat 6 is long, the central portion in the longitudinal direction of the slat 6 hangs down due to gravity, and there is a risk of rubbing by interference. In this case, abnormal noise may be generated due to rubbing, or the slat 6 may be damaged. Therefore, according to the present embodiment, as shown in FIGS. 5 to 7, an attachment 100 that functions as a cross-sectional posture displacement portion is separately provided on the linear connecting member 7 that is a component of the shutter curtain 1. Yes. That is, as shown in FIG. 6, the attachment 100 is attached to the first link 71 corresponding to the adjacent slat 6 sc that causes rubbing among the linear coupling members 7 via the attachment 77 (for example, a rivet). Yes. The attachment 100 is formed of a molded product obtained by press-molding a metal plate. As shown in FIG. 6, the first flange portion 101 having a mounting hole 104 through which the mounting tool 77 is inserted and the first link 71 are fitted. A second flange portion 102 that faces the first flange portion 101 so as to form the mounting groove 108, and a third flange that is bent from the second flange portion 102 and faces the outer peripheral surface of the axial protrusion 64. Part 103.

  As shown in FIG. 6, the first flange portion 101 and the second flange portion 102 are along the direction perpendicular to the axis of the axial protrusion 64 of the adjacent slat 6sc. The third flange portion 103 is along the shaft core 64p of the axial protrusion 64 of the adjacent slat 6sc, and has a displacement protrusion 106 at the tip. As shown in FIGS. 7 and 8, the displacement protrusion 106 of the attachment 100 can abut against the outer surface of the stopper portion 600 of the shaft-like protrusion 64 and restricts the posture of the adjacent slat 6sc. As described above, the attachment 100 is attached to the first ring 71 of the adjacent slat 6sc in the linear connecting member 7. For this reason, as can be understood from FIG. 8, the displacement protrusion 106 at the tip of the attachment 100 protrudes from the contacted surface 711 of the stopper target 710 of the first link 71 toward the stopper 600 by ΔK2. As a result, the displacement protrusion of the tip of the attachment 100 is made before the contact surface 711 of the stopper portion 710 of the first link 71 contacts the outer surface of the stopper 600 of the axial protrusion 64 of the adjacent slat 6sc. The portion 106 can abut on the outer surface of the stopper 600 of the axial protrusion 64 of the adjacent slat 6sc. As a result, the cross-sectional posture of the adjacent slat 6sc can be inclined in the direction of the arrow RS (see FIGS. 4 and 8) more than the slat posture according to the comparative example. In this case, as can be understood from FIG. 4 according to the present embodiment, the rotation slat 6o before the rotation with respect to the virtual line HP connecting the shaft cores 64p of the shaft-like protrusions 64 of the slat 6 The end portion 60ue of the upper fitting portion 60u protrudes ΔW1 toward the interior 10 side, and the end portion 61de of the lower fitting portion 61d of the rotating slat 6o is located substantially on the virtual line HP. ing. On the other hand, as can be understood from FIG. 4, with respect to the adjacent slat 6sc existing directly below the rotating slat 6o, the end 60ue of the upper fitting portion 60u projects ΔW1 + α toward the room 10 side. ing. ΔW1 + α is larger than ΔW1 in which the end portion 60ue of the upper fitting portion 60u of the rotating slat 6o protrudes toward the interior 10 side. Further, as can be understood from FIG. 4, the end 61de of the lower fitting portion 61d of the adjacent slat 6sc is displaced so as to protrude ΔW3 toward the outdoor 12 side which is the reverse direction.

  That is, according to the present embodiment, since the attachment 100 is attached to the first link 71 (part constituting the suspension member) of the adjacent slat 6sc, the upper end portion of the adjacent slat 6sc in the cross section of the slat 6 Is displaced in one direction (inside the room 10) around the axial protrusion 64, and the lower end of the adjacent slat 6sc is displaced in the other direction (outdoor 12 side) around the axial protrusion 64. In addition, the cross-sectional posture of the adjacent slat 6sc is inclined around the axial protrusion 64. In other words, with the attachment 100, the sectional posture of the adjacent slat 6sc can be inclined in the direction of the arrow RS (see FIG. 4) around the axis 64p with respect to the virtual line HP. Therefore, according to the present embodiment, as shown in FIG. 4, the end portion of the lower fitting portion 61d of the rotating slat 6o before the rotation and the end portion of the upper fitting portion 60u of the adjacent slat 6sc. A gap D2 (D2> D1) is formed between them. For the slats 6 other than the adjacent slats 6sc, the gap between the slats 6 is set to D1 (D2> D1) as in the comparative example.

  As described above, according to the present embodiment, the attachment 100 having a metal fitting shape is attached to the first link 71 facing the adjacent slat 6sc of the linear connecting member 7. As a result, when the shutter curtain 1 is closed in the closing direction (the direction of the arrow H2), the attachment 100 tilts the sectional posture of the adjacent slat 6sc by a small amount around the axis 64p. As a result, the adjacent slat 6sc has a direction in which the degree of interference due to contact between the end of the lower fitting portion 61d of the rotating slat 6o and the end of the upper fitting portion 60u of the adjacent slat 6sc is reduced or eliminated. The end portion 60ue of the upper fitting portion 60u is inclined and displaced toward the room 10 side. According to such a present Example, even if there exists a secular change etc., the rotation slat 6o is rotated centering | focusing on the axis 64p of the axial protrusion part 64 so that the window opening 6e may be formed. In this case, the gap D2 suppresses or eliminates the interference between the end portion 61de of the lower fitting portion 61d of the rotating slat 6o and the end portion 60ue of the upper fitting portion 60u of the adjacent slat 6sc. . As a result, the generation of abnormal noise due to rubbing is suppressed, damage to the slats 6 is suppressed, and it is possible to contribute to durability and long life of the slats 6.

  In addition, according to the present embodiment, as shown in FIG. 8, the displacement protrusion 106 of the attachment 100 faces the stopper portion 600 of the axial protrusion 64 of the adjacent slat 6sc. For this reason, the displacement protrusion 106 of the attachment 100 is close to the shaft core 64p serving as a rotation center for inclining the sectional posture of the adjacent slat 6sc. Therefore, when the sectional posture of the adjacent slat 6sc is tilted about the axis 64p so as not to rub, the distance ΔK1 (see FIG. 8) between the displacement projection 106 of the attachment 100 and the axis 64p is reduced. it can. As a result, the protrusion amount ΔK2 (see FIG. 8) of the displacement protrusion 106 of the attachment 100 can be reduced. In this case, there is an advantage that the change in the appearance structure can be reduced. As shown in FIG. 8, the attachment 100 is attached so as to overlap the stoppered portion 710 that is bent so as to form a hook shape of the first link 71, so that the attachment 100 is protected by the stoppered portion 710, The protection against the attachment 100 can be improved. According to this embodiment, when manufacturing the shutter device, the attachment 100 may be attached in advance to the linear connecting member 7 corresponding to the adjacent slat 6sc. Alternatively, the above-mentioned rubbing problem does not occur when the shutter device is installed, but the above-mentioned rubbing problem may occur due to secular change or the like. In this case, when a problem of rubbing is found, the attachment 100 may be attached later to the linear connecting member 7 corresponding to the adjacent slat 6sc that causes rubbing.

  As described above, the attachment 100 is attached to the adjacent slat 6sc immediately below the rotating slat 6o. FIG. 9 shows a normal slat 6 with no attachment 100 attached. The normal slat 6 means a slat other than the adjacent slat 6sc among the slats 6 described above. As shown in FIGS. 9A and 9B, as in the case of the adjacent slat 6sc, the linear connecting member 7 is adjacent to the first link 71 having a vertically long shape in the height direction. A second link 72 having a vertically long shape for pivotally supporting the first link 71; a long hole 73 provided at an upper end portion of the first link 71 and extending in the height direction (arrow H direction); It has a protruding fitting pin 74 (fitting body) provided on the link 72. The first link 71 is pivotally connected to an axial protrusion 64 of the slat 6 integrally with an end portion in the longitudinal direction of the slat 6 by a pivot pin 6w (connection element). However, as shown in FIGS. 9A and 9B, the attachment 100 is not attached to the first link 71. In addition, according to the present Example, although the attachment 100 is attached to the 1st link 71 of the linear connection member 7 as mentioned above, you may decide to attach to the 2nd link 72 depending on the case.

  FIG. 10 shows a second embodiment. The present embodiment basically shows the same configuration and effect as the first embodiment. As in the first embodiment, as shown in FIG. 10, the first link 71B constituting the linear connecting member 7 functioning as a suspension member is formed by press molding of a metal material. A cross-sectional posture displacement portion 100B is integrally formed by press molding on the first link 71B. The cross-sectional posture displacement portion 100B is a protrusion corresponding to the displacement protrusion 106 of the attachment 100 according to the first embodiment. Therefore, as in the first embodiment, the cross-sectional posture displacement portion 100B formed integrally with the first link 71B of the linear connecting member 7 reduces or eliminates rubbing between the rotating slat 6o and the adjacent slat 6sc. The sectional posture of the adjacent slat 6sc is displaced in the direction to be eliminated. Therefore, when the rotating slat 6o is rotated so as to form the window opening 6e, even if there is an influence of aging, dimensional tolerance, etc., the end of the lower fitting portion 61d of the rotating slat 6o is adjacent to the end. The interference with the end of the upper fitting portion 60u of the installed slat 6sc and rubbing is suppressed or eliminated. As a result, abnormal noise caused by rubbing is suppressed, damage to the slats 6 is suppressed, and it is possible to contribute to durability and long life of the slats 6.

  When manufacturing the shutter device, a first link 71B that can solve the problem of rubbing may be attached in advance instead of the first link of the linear connecting member 7 corresponding to the adjacent slat 6sc. Alternatively, when the shutter device is installed, the above-mentioned rubbing problem does not occur, but the above-mentioned rubbing problem may occur due to secular change or the like. In this case, instead of the first link of the linear connecting member 7 that cannot solve the problem of rubbing, a first link 71B having a cross-sectional posture displacement portion 100B that can eliminate the problem of rubbing may be attached later.

  11 and 12 show the third embodiment. The present embodiment basically shows the same configuration and effect as the first and second embodiments. As shown in FIG. 11 and FIG. 12, the axial protrusion 64 constituting the slat cap 62 of the adjacent slat 6sc is molded using resin as a base material. A cross-sectional posture displacement portion 110C is integrally formed of resin on the outer wall surface of the stopper portion 600 of the axial protrusion 64 of the slat cap 62. 110 C of cross-sectional attitude | position displacement parts are provided so that the to-be-contacted surface 711 of the to-be-stopped part 710 formed in the 1st link 71 of the linear connection member 7 may be faced and contacted. Accordingly, the cross-sectional posture displacement portion 110C integrally formed with the shaft-shaped protruding portion 64 has a cross-section of the adjacent slat 6sc in a direction to reduce or eliminate the friction between the rotating slat 6o and the adjacent slat 6sc. The posture can be displaced. Therefore, the pivoting slat 6o pivoting so as to form the window opening 6e suppresses the rubbing between the pivoting slat 6o and the adjacent slat 6sc even if there is an influence of aging, dimensional tolerance, or the like. It will be resolved. As a result, abnormal noise is suppressed, damage to the slats 6 is suppressed, and it is possible to contribute to durability and long life of the slats 6.

  When manufacturing the shutter device, the adjacent slat 6sc in which the cross-sectional posture displacement portion 110C is integrally formed may be attached in advance instead of the slat that may cause the above-mentioned rubbing problem. Alternatively, the above-mentioned rubbing problem does not occur when the shutter device is installed, but the above-mentioned rubbing problem may occur due to secular change or the like. In this case, instead of the slat that causes the problem of rubbing, the adjacent slat 6sc that does not cause the problem of rubbing because the cross-sectional posture displacement portion 110C is integrally formed may be attached later. According to the present embodiment, the sectional posture displacement portion 110C is integrally formed on the outer peripheral surface of the axial protrusion 64 of the adjacent slat 6sc, but this is not limiting, and the axial protrusion of the adjacent slat 6sc is not limited thereto. A cross-sectional posture displacement portion 110C, which is an attachment, may be attached to the outer peripheral surface of 64 by an adhesive or a fastener.

  13 to 21 show a fourth embodiment. The present embodiment shows basically the same configuration and operation effects as the first to third embodiments. 13 and 14 show the main part of the slat 6. FIG. FIG. 13 shows the vicinity of a slat cap 62 attached to a slat 6o (o: open) functioning as a rotating slat set so as to be in an open posture. As shown in FIG. 13, 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 at a distance ΔL (see FIG. 13) in the longitudinal direction (arrow L direction) of the slat 6.

  Among the plurality of slats 6 constituting the shutter curtain 1, slats 6s (s: shut) other than the rotating slats 6o are set so as not to be in the open posture. This is to prevent the window opening 6e from being formed more than necessary mainly for security reasons.

 FIG. 14 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. 13 and FIG. 14, 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.

  15 and 16 show the shutter curtain 1 in a state in which the slat 6o that can be set to the open posture is not in the open posture, but is in the closed posture. As shown in FIG. 16, 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. 18, the vertical support column 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. 15 and 16, the actuator 8 is detachably attached to the upper end portion of the guide rail portion 53 of the vertical column 5 which 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 A resin lid member 81 attached to 80, a hard resin or metal actuator 83 attached to the lid member 81, and a slat opening mechanism 84 (see FIG. 15) attached to the guide rail cap member 80. It has. 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. 20).

  According to the present embodiment, as shown in FIGS. 17 to 19, 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. 17, the cover 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. As shown in FIG. 17, the base end portion 82 a of the spring portion 82 is rotatably connected to the lid member 81. The projecting tip 82c of the spring portion 82 is a free end, faces the upper surface 83u that is part of the operating body 83, and maintains the cross-sectional posture of the operating body 83 at a fixed position (substantially horizontal position). It has a function to do. The lid member 81 has a long hole 81x and a hole 81y.

  Although the actuating body 83 is regulated by the spring portion 82, it can be displaced in the avoidance direction (the direction of the arrow F1 shown in FIG. 17) against the urging 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. 17) by the biasing force of the spring portion 82 and return to the home position. 18 and 19 are sectional views of the guide rail portion 53 in the direction perpendicular to the axis. As shown in FIGS. 18 and 19, the operating body 83 has an operating protrusion 83 e that protrudes toward the axial protrusion 64 of the slat 6. 18 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 S2 and switched to the retracted position B. FIG. In this case, as shown in FIG. 18, in the longitudinal direction of the slat 6 (arrow L direction), 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 rotating slat 6o and the operating protrusion 83e of the operating body 83 are not allowed to engage (contact). In this case, even the rotating slat 6o does not rotate. On the other hand, FIG. 19 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. 19, 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 of the slat 6 can be engaged (contacted).

  As shown in FIG. 15, the slat opening 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 portion 53. ing. The slat opening mechanism 84 includes a driving source 85, a link-like rotating body 86 that is rotated by the driving source 85, and a biasing coil spring that constantly biases the rotating body 86 toward the retracted position B. A member 86h. Here, the urging member 86h always urges the rotating body 86 toward the retreat position B in the retreat direction (arrow E1 direction). For this reason, even if the drive source 85 breaks down, the rotating body 86 is not in the engagement position A (position where the slat 6o is in the open position) but in the retracted position B (in which 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.

  As shown in FIG. 15, the drive source 85 is held by the guide rail cap member 80 of the actuator 8, and advances in one direction (K1 direction, upward direction) and the other direction (K2 direction, And a movable plunger 85c that can be retracted in the downward direction. 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. As shown in FIG. 15, the rotating body 86 has a center of rotation in the guide rail cap member 80 of the actuator 8 so as to be rotatable in one direction (arrow D1 direction) and the other direction (arrow D2 direction). It is pivotally supported by the fixture 87 which becomes. The rotating body 86 and the movable plunger 85c are connected by a pin-shaped first connecting tool 88 so as to be rotatable. Specifically, the long hole 86c of the rotating body 86 and the first connector 88 of the movable plunger 85c are fitted. The distal end portion 86e of the rotating body 86 and the base end portion 83k of the operating body 83 are connected to each other by a pin-shaped second connecting tool 89 so as to be rotatable.

  Here, as can be understood from FIG. 15, 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 rotating body 86 is attached. It moves in the engaging direction (arrow D1 direction) around the tool 87, and as a result, the operating protrusion 83e of the operating body 83 moves in the engaging direction (arrow E1 direction) to 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 rotating body 86 is moved in the retracting direction (arrow indicated by the attachment 87). D2 direction), and consequently 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. 15, the movable plunger 85c of the drive source 85 is moved in the retracting direction (arrow K2 direction), and the rotating body 86 is biased. It is urged by the member 86h and rotates in the retreat direction (arrow D2 direction) around the rotation center (attachment tool 87) of the rotation body 86. As a result, the operating body 83 moves in the retreat direction (arrow E2 direction) and is retreated to the retreat position B (see FIGS. 15 and 18). 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. 15, 16, and 18). For this reason, the passage 57 (see FIG. 18) 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. 18) are separated and do not engage (contact) each other. Therefore, the slat 6o does not rotate to the open position, but is lowered downward in the closed position. Therefore, when the shutter curtain 1 is closed, none of the rotating slats 6o is rotated to the open position, and no window opening 6e is formed between the adjacent rotating slats 6o (FIG. 16). 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. 18).

  Next, the case where the rotating 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), and the rotating body 86 is moved in the engagement direction (arrow D1 direction). The protrusion 83e moves in the engagement direction (arrow E1 direction). As a result, the operating projection 83e of the operating body 83 is switched to the engaging position A (see FIGS. 20 and 19). 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. 20 and 21, the first engaging portion 67 of the rotating slat 6 o is engaged (contacted) with the operating protrusion 83 e of the operating body 83. Accordingly, the rotation slat 6o rotates about the shaft-like protrusion 64 in the opening posture direction (the direction of the arrow M1 shown in FIG. 21). Thus, the 1st engaging part 67 can function as a rotation starting point part used as the starting point which rotates the rotation 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 the shutter curtain 1 is closed, the slat 6o in which the first engaging portion 67 is formed rotates in the opening posture direction (arrow M1 direction, RK direction). Therefore, as shown in FIGS. 20 and 21, a window opening 6e is formed between adjacent slats 6o. The window 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, a biasing force in a direction (arrow M2 direction) in which the slat 6 is in the closed posture is acting on the slat 6o by a spring (not shown), but the second engagement portion 68 is connected to the second guide passage 52. Since it hits the wall surface 52c (see FIG. 21), the slat 6o cannot be rotated in the closed posture direction (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, the window opening 6e is not formed between the adjacent slats 6s for the non-open slats 6s. Therefore, according to the present embodiment, the slat corresponding to the position where the window opening 6e is to be formed may be the rotating slat 6o having both the first engaging portion 67 and the second engaging portion 68. The slat corresponding to the position where the window 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 security, etc., the first engaging portion 67 and the second engaging portion 68 may be formed on the upper several of the plurality of slats 6 to form the rotating slat 6o. it can. In this case, even if the rotating 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. The wear of the second 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.

  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. 17, in order to avoid the interference, the operating body 83 is supported by the lid member 81 of the actuator 8 so as to be displaceable in the avoidance direction (arrow F1 direction, upward). 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 engaging portion 68, the second engaging portion 68 of the slat 6o that moves upward moves the lower surface 83d (FIG. 17) of the operating projection 83e of the operating body 83. The operating body 83 can be displaced in the avoidance direction (arrow F1 direction, upward) with the second connector 89 as the center. As a result, the slat 6o is always urged in the closed posture direction (arrow M2 direction shown in FIG. 21) 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 window opening 6e can be formed by rotating the rotating 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 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.

  Further, according to the present embodiment, the actuator 8 including the operating body 83 and the slat opening mechanism 84 is attached to the upper end opening 53f of the guide rail portion 53 of the vertical column 5 to thereby provide the guide rail portion 53 ( At the upper end of the 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. Furthermore, according to the present embodiment, the first engaging portion 67 for making the slat 6o open and the second engaging portion 68 for maintaining 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.

  Also in this embodiment, as in the first embodiment, the attachment 100 attached to the first link 71 of the linear connecting member 7 is adjacent to the rotating slat 6o when the rotating slat 6o rotates. The cross-sectional posture of the adjacent slat (corresponding to the slat directly below the lowermost rotating slat 6o) is displaced in a direction in which the degree of interference due to contact with the installed slat is reduced or eliminated. As a result, as shown in FIG. 4, when the slat 6 is rotated in the rotation direction with the shaft-like protrusion 64 as the rotation center to form the window opening 6e, even if there are aging, dimensional tolerances, etc. The rubbing of the lower end of the rotating slat 6o and the upper end of the adjacent slat 6sc is suppressed or eliminated. As a result, generation | occurrence | production of abnormal noise is suppressed, damage to the slat 6 is suppressed, and it can contribute to durability and long life of the slat 6.

(Other)
According to the first embodiment, as shown in FIG. 4, when the sectional posture of the adjacent slat 6 sc is inclined, the end of the upper fitting portion 60 u of the adjacent slat 6 sc is displaced toward the indoor 10 side and The end of the lower fitting portion 61d of the installed slat 6sc is displaced toward the outdoor 12 side. Conversely, the end of the upper fitting portion 60u of the adjacent slat 6sc is displaced toward the outdoor 12 side, and the end of the lower fitting portion 61d of the adjacent slat 6sc is directed toward the indoor 10 side. It may be displaced. According to the fourth 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 drive source of the actuator 8 when the slat 6o is put into the closed posture. However, 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 position, and the actuator 8 is turned into the closed position. The drive source 85 may be turned on.

  According to the fourth 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. On the upper side of the slat 6, a convex upper fitting portion 60u is formed. A concave lower fitting portion 61d is formed on the lower side of the slat 6. The concavo-convex relationship may be reversed.
