  Hereinafter, a shutter device according to a first embodiment of the present invention will be described with reference to the accompanying drawings. 1 and 2 are perspective views of the shutter device. FIG. 1 is a perspective view of the front side of the shutter device, and FIG. 2 is a perspective view of the back side of the shutter device. The shutter device includes a pair of left and right guide rails 1 that extend in parallel, and a plurality of slats 2 that move along the guide rails 1. The guide rail includes an opening section 1a that extends linearly in the vertical direction along the left and right edges of the opening of the building, and a connecting section 1b that bends to the back side of the opening at the upper end of the opening section 1a. The storage section 1c extends linearly in the horizontal direction from the connecting section 1b. The storage section 1c and the connecting section 1b of the guide rail 1 are hidden behind the ceiling (see FIG. 4).

  As shown in FIGS. 1 and 2, a plurality of slats 2 are spanned between a pair of left and right guide rails 1. The slats 2 are thin and extend in the left-right direction. The plurality of slats 2 are not connected to each other and are separated from each other. Each of the plurality of slats 2 is attached to a pair of brackets 3 on the left and right. When the plurality of slats move to the opening section 1a, the plurality of slats are arranged so that the surfaces thereof are arranged in one plane. The surface of the slat 2 is decorated so as to be suitable for the interior. The same pattern or color may be applied to each of the plurality of slats 2, or one pattern may be created when a plurality of slats 2 are combined.

  It is desirable that the slats 2 are supplied through a distribution route different from the functional parts (metal parts) composed of the guide rails 1, the brackets 3 and the like. This is because the slat 2 is required to have a design rather than a functional aspect.

  3 and 4 show an example in which the shutter device is attached to the opening of the wall surface. 3 shows a cross-sectional view of the shutter device in the horizontal plane, and FIG. 4 shows a cross-sectional view of the shutter device in the vertical plane. As shown in FIG. 3, the shutter device is attached to the recessed wall surface 4. On the left and right sides of the opening 4a of the wall surface 4, there are formed steps 4b corresponding to the thickness of the shutter device. The height of the step 4b is equal to the height of the shutter device, and the surface of the slat 2 and the wall surface 4 are arranged on the same plane (coplanar).

  The guide rail 1 is coupled to the step 4b using a coupling means such as a screw 5. The cross-sectional shape of the guide rail 1 is a square shape. A slit 6 extending along the guide rail 1 is formed on one side of the square front side. A bracket body 7 having an L-shaped cross section projects from the slit 6. Two roller guide passages 8 are formed in the guide rail 1 with the bracket body 7 interposed therebetween. The two roller guide passages 8 are fitted with left and right rollers 9 attached to both surfaces of the bracket body 7. The cross-sectional shape of the two roller guide passages 8 is substantially equal to the cross-sectional shape of the roller 9. When the bracket body 7 moves along the guide rail 1, the outer peripheral surface of the roller 9 comes into contact with one of the opposing inner wall surfaces of the roller guide passage 8. Since the outer peripheral surface of the roller 9 is surrounded by the guide rail 1, the bracket body 7 cannot be extracted from the guide rail 1 to the front side of the opening.

  FIG. 5 shows a detailed view of the bracket body 7. 5A shows a front view of the bracket body 7, and FIG. 5B shows a side view of the bracket body 7. FIG. A piece 11 on the front side of the bracket body 7 serves as an attachment surface to which the slat 2 is attached. A female screw 11 a is processed on the front-side piece 11. Three roller mounting female screws 12 a, 12 b, and 12 c for mounting the roller 9 are processed on the piece 12 on the side surface side of the bracket body 7. A roller 9 is attached to the upper and lower roller mounting female screws 12a and 12c from the front side, and a roller 9 is attached to the central roller mounting female screw 12b from the rear side. By connecting a total of three rollers 9 on the left and right sides of the bracket body 7, the travel of the bracket body 7 can be stabilized (see FIG. 7). When the slat 2 is raised or lowered, the movement of the three rollers 9 of the bracket 3 is guided to the roller guide passage 8 of the guide rail 1 (see FIG. 4).

  FIG. 6 shows the set screw 14. The set screw 14 has a male screw 14b and a disc-shaped flange portion 14a as a head. As shown in FIG. 1, the slat 2 has a through hole 15 through which the male screw 14 b of the set screw 14 passes. By passing the set screw 14 through the through hole 15 of the slat 2 and fitting the set screw 14 into the female screw 11 a of the bracket 3, the slat 2 can be attached to the mounting surface of the bracket 3. Further, when the slat 2 is removed from the bracket 3, the set screw 14 may be removed from the bracket 3. The slat 2 can be attached to and detached from the bracket 3 while the bracket 3 is attached to the guide rail 1.

  As shown in FIG. 3, the mounting surface 11 of the bracket body 7 to which the slat 2 is mounted protrudes beyond the guide rail 1 to the front side of the shutter device. When viewed from the front side of the shutter device, both end portions of the slat 2 hide the guide rail 1.

  FIG. 7 shows an exploded perspective view of the bracket 3. As described above, the plurality of slats 2 are separated from each other. In order to move the slats 2 in conjunction with each other, a pair of brackets 3 adjacent to each other in the vertical direction among the plurality of brackets 3 are connected by a connecting member 17. The roller 9 is screwed to the bracket body 7 via the bush 18. A through hole 17 a through which the bush 18 passes is opened at both ends of the connecting member 17 in the vertical direction. The connecting member 17 rotates with respect to the bracket body 7 in a plane perpendicular to the surface of the slat 2 around the bush 18. Thereby, the connected series of brackets 3 can be moved along the guide rail 1.

  The slat 2 may be operated manually or electrically. If the lowermost one of the plurality of slats 2 is held and lowered by hand, the plurality of slats 2 are lowered in conjunction with each other, so that the opening can be closed. On the other hand, if the single slat at the bottom is raised, the plurality of slats rise in conjunction with each other, so that the opening can be opened. When the opening is opened, the plurality of slats are moved to the storage section 1c and are hidden in the ceiling. Note that the plurality of slats 2 that have risen up to the storage section 1c are arranged in one plane in the same manner as when the slats 2 are lowered to the opening section 1a.

  As a method of electrically operating the slat 2, for example, a method of connecting one end of the chain or wire to the lowermost slat 2 and pulling up or down the chain or wire by an electric motor is conceivable. In addition, there is a method in which a rack is provided along the guide rail 1, a pinion that meshes with the rack is attached to the bracket, the pinion is rotated by an electric motor, and the bracket is raised or lowered by a rack and pinion mechanism.

  8 to 10 show a shutter device according to the second embodiment of the present invention. 8 shows a perspective view of the shutter device as seen from the front side, FIG. 9 shows an exploded perspective view of the shutter device as seen from the front side, and FIG. 10 shows an exploded perspective view of the shutter device as seen from the back side. As in the shutter device of the first embodiment, the shutter device of this embodiment is supported by a pair of left and right guide rails 21 extending in parallel, a plurality of brackets 22 moving along the guide rails 21, and a plurality of brackets. A plurality of slats 23.

  The bracket 22 is not separated like the bracket 3 of the first embodiment, but is spanned between the pair of left and right guide rails 21. Each of the plurality of brackets 22 is attached with a plurality of slats 23 that are thin and extend in the left-right direction. The plurality of slats 23 are not connected to each other and are separated from each other. The configuration of the slat 23 and the set screw 24 for attaching the slat 23 to the bracket 22 is the same as that of the shutter device of the first embodiment.

  The guide rail 21 has an opening section 21a that extends linearly in the vertical direction along the left and right edges of the opening of the building, and a connecting section 21b that bends to the back side of the opening at the upper end of the opening section 21a. And a storage section 21c extending linearly in the horizontal direction from the connecting section 21b. The storage section 21c and the connecting section 21b of the guide rail 21 are hidden behind the ceiling (see FIG. 12).

  11 and 12 show an example in which the shutter device is attached to the opening of the wall surface. FIG. 11 shows a sectional view of the opening in the horizontal plane, and FIG. 12 shows a sectional view in the vertical plane of the shutter device. In this embodiment, as shown in FIG. 11, the guide rail 21 is attached between the pair of opposing side wall surfaces 26 a of the recessed wall surface 26. The width between the pair of side wall surfaces 26a is equal to the width of the shutter device. The mounting surface 31 of the bracket 22 to which the slat 23 is mounted protrudes beyond the guide rail 21 to the front side of the opening. The slat 23 is attached to the attachment surface 31 of the bracket 22 so that the surface of the slat 23 is in one plane with the wall surface 26 (so as to be flush with each other).

  As shown in FIG. 11, the cross-sectional shape of the guide rail 21 is a U-shaped (C-shaped) cross-section from which one side of the quadrangle is removed, and includes a bottom portion 27 and a pair of side portions 28 orthogonal to the bottom portion 27. Is done. The pair of guide rails 21 have openings facing each other. The inner space of the rectangular guide rail 21 forms a roller guide passage 29. The cross-sectional shape of the roller guide passage 29 is substantially equal to the cross-sectional shape of the roller 30. When the bracket 22 moves along the guide rail 21, the outer peripheral surface of the roller 30 contacts one of the pair of side portions 28 of the guide rail 21 that face each other. Since the outer peripheral surface of the roller 30 is surrounded by the guide rail 21, the roller 30 cannot be extracted from the guide rail 21 to the front side.

  FIG. 13 is an exploded perspective view of the bracket 22. The bracket 22 includes a bracket body 32 that extends between a pair of left and right guide rails, and a roller 30 that is rotatably attached to the left and right ends of the bracket body 32. The bracket body 32 is formed by projecting a pair of leg portions 33 from a plate-like pedestal 34. The bracket body 32 extends between the guide rails 21 in the left-right direction. The shaft portion of the roller 30 is screwed to both ends of the leg portion 33 in the longitudinal direction via bushes 35. In this embodiment, a total of four rollers 30 are attached to one bracket body 32.

  As described above, the plurality of slats 23 are separated from each other. In order to move the slats 23 in conjunction with each other, a pair of brackets 22 adjacent in the vertical direction among the plurality of brackets 22 are connected by a connecting member 37. The connecting member 37 is thin and elongated. A pair of through holes 37 a into which the bushes 35 are inserted are opened at both ends of the connecting member 37. The connecting member 37 can rotate with respect to the bracket 22 in a plane perpendicular to the surface of the slat 23 around the bush 35. Thereby, the connected series of brackets 22 can be moved along the guide rail 21 (see FIG. 12).

  14 to 17 show a shutter device according to the third embodiment of the present invention. 14 and 15 are perspective views of the shutter device, and FIGS. 16 and 17 are front views of the shutter device. 14 and 16 show a state in which the plurality of slats 42 are moved to the opening section 41a on the lower end side of the guide rail 41 and the opening is closed, and FIGS. 15 and 17 show the plurality of slats 42. Shows a state in which the opening is opened by moving to the storage section 41c on the upper end side of the guide rail 41. A plurality of slats 42 are stretched around a pair of guide rails 41, and the plurality of slats 42 move along the guide rails 41 to open and close the opening, in the first and second embodiments. This is the same as the shutter device. However, in the shutter device of this embodiment, unlike the shutter devices in the first and second embodiments, as shown in FIG. 15, when the slat 42 moves to the storage section 41c, a plurality of slats 42 are provided. Are stored in a state of being parallel to each other.

  As shown in FIGS. 14 and 15, the shutter device of this embodiment is assembled to a pair of left and right guide rails 41 that extend parallel to each other and guide the movement of the bracket 43, and the pair of guide rails 41. , A plurality of brackets 43 that can move along the pair of guide rails 41, and a plurality of slats 42 that are spanned between the pair of guide rails 41 and supported by the plurality of brackets 43. A pair of left and right brackets 43 are attached to the pair of left and right guide rails 41, and one slat 42 is supported by the pair of left and right brackets 43. The plurality of slats 42 are not connected to each other.

  As shown in FIG. 16, when the plurality of slats 42 move to the opening section 41 a on the lower end side of the guide rail 41, the guide rail 41 is hidden behind both ends of the slat 42. In the opening section 41 a, the inner method (inner distance) of the pair of guide rails 41 is shorter than the length of the slat 42 in the longitudinal direction. On the other hand, as shown in FIG. 17, when the plurality of slats 42 move to the storage section 41 c, the plurality of slats 42 are sandwiched between the pair of guide rails 41. In the storage section 41 c, the inner method of the pair of guide rails 41 is longer than the length of the slat 42 in the longitudinal direction. Since the length of the slat 42 in the longitudinal direction is constant, the inner method of the pair of guide rails 41 in the storage section 41c is larger than the inner method of the pair of guide rails 41 in the opening section 41a.

  FIG. 18 shows a horizontal cross-sectional view of the shutter device attached to the recessed wall surface 46. Steps 47 are formed on the left and right sides of the opening of the wall 46. The height of the step 47 is equal to the height of the shutter device, and the wall surface 46 and the surface of the slat 42 are arranged in the same plane. FIG. 18 also shows a cross-sectional view of the guide rail 41. The cross-sectional shape of the guide rail 41 is symmetrical. In the guide rail 41, a single main roller guide passage 48 extending in the longitudinal direction and two sub roller guide passages 49 are formed. The main roller guide passage 48 is formed in the center of the guide rail 41 and on the back side, and the two sub-roller guide passages 49 are formed on the left and right sides of the guide rail 41 and on the front side. A main roller 56 of the bracket 43 is accommodated in the main roller guide passage 48 so as to be capable of rolling, and a sub roller 57 of the bracket 43 is accommodated in the sub roller guide passage 49 so as to be capable of rolling. In the sectional view of the guide rail 41, the rotation axis of the main roller 56 and the rotation axis of the sub roller 57 are orthogonal to each other. Thus, rattling does not occur when the bracket 43 moves along the guide rail 41.

  FIG. 19 shows a side view of the guide rail 41. The guide rail 41 is disposed in the opening, and extends in a straight line in the vertical direction. The guide rail 41 is disposed in the back of the ceiling. The guide rail 41 extends in the vertical direction from the upper end of the opening section 41a. It is divided into a connecting section 41b that is divided and extends in the horizontal direction, and a storage section 41c that is arranged inside the ceiling and connected to one end of the connecting section 41b. In the storage section 41c, the guide rail 41 extends in a straight line in the horizontal direction in a bifurcated state. The reason why the guide rail 41 is bifurcated is to store the slats 42 in a state of being arranged in parallel.

  FIG. 20 shows an exploded perspective view of the guide rail 41 and the bracket 43. The guide rail 41 is disposed behind the both ends of the slat 42 in the opening section 41a when viewed from the front of the shutter device (see FIG. 16). On the other hand, the guide rail 41 is arrange | positioned in the side part of the longitudinal direction of the slat 42 in the accommodating part area | region 41c (refer FIG. 17). In order to realize this, the guide rail 41 of this embodiment is twisted 90 degrees in the connecting section 41b. FIG. 21 shows a change in the cross-sectional shape of the guide rail 41 in the twisted connecting section 41b. As shown in FIG. 21 (C), the guide rail 41 disposed behind the slat 42 is twisted to gradually increase the longitudinal direction of the slat 42 as shown in FIGS. 21 (B) and 21 (A). It will be located on the side of. When viewed from the guide rail 41, the slat 42 enters the inside of the guide rail 41. The center of rotation of the guide rail 41 is the hinge shaft 52 of the bracket 43 attached to the back surface of the slat 42.

  As shown in FIG. 20, the guide rail 41 is bifurcated after being twisted. Originally, the one main roller guide passage 48 branches into two main roller guide passages 48 a and 48 b as the guide rail 41 branches. Originally, the two sub-roller guide passages 49 extend in a straight line from a state in which they are arranged in parallel to branch into two branches in the connecting section 41b and branch into two branches in the storage section section 41c. In this embodiment, two sub-roller guide passages are formed in each of the bifurcated guide rails 41 in order to align the shape of the bifurcated guide rails 41 in the storage section 41c. Only one side of the two sub-roller guide passages is connected to the sub-roller guide passage 49 of the connecting section 41b. Since the guide rail 41 in the connecting section 41b is twisted and branched, the whole is divided into a plurality of divided pieces. The divided pieces are connected by a stopper 53.

  The bracket 43 includes a bracket main body 54 to which the slat 42 is attached, and two guide rail engaging portions 55 that are coupled to the bracket main body 54 at different positions in the longitudinal direction of the guide rail 41. One of the two guide rail engaging portions 55 is guided to one of the two sub roller guide passages 49, and the other of the two guide rail engaging portions 55 is guided to the other of the two sub roller guide passages 49. Of the two guide rails 41 branched in the storage section 41c, the upper guide rail 41 is guided by the upper guide rail 41 and the lower guide rail 41 is guided by the lower guide rail 41. 55 is guided.

  The guide rail engaging portion 55 is coupled to the bracket main body 54 via a hinge. The guide rail engaging portion 55 has a main roller 56 inserted into the main roller guide passage 48 of the guide rail 41 and a sub roller 57 accommodated in one of the two sub roller guide passages 49. The main roller 56 is coupled to a main roller support shaft 60 protruding from the hinge piece 59. The main roller 56 rotates around the main roller support shaft 60. The sub roller 57 is connected to the main roller support shaft 60 via an L-shaped arm 58 and revolves (revolves) around the main roller support shaft 60.

  A female screw 61 is processed in the bracket body 54. A through hole 62 is machined at a position of the slat 42 corresponding to the female screw 61 of the bracket body 54. By passing the set screw 63 through the through hole 62 of the slat 42 and fitting the set screw 63 into the female screw 61 of the bracket body 54, the slat 42 can be attached to the mounting surface of the bracket body 54. When removing the slat 42 from the bracket body 54, the set screw 63 may be removed from the bracket body 54. The slat 42 can be attached to and detached from the bracket body 54 while the bracket 43 is attached to the guide rail 41. The mounting surface 65 of the bracket body 54 to which the slat 42 is mounted protrudes beyond the guide rail 41 to the front side of the shutter device.

  When the slat rises, the bracket 43 moves from the opening section 41a to the connecting section 41b. Since the connecting section 41b is twisted, the guide rail engaging portion 55 rotates around the hinge shaft 52 so that the hinge piece 59 opens so as to correspond to the twist of the guide rail 41, as shown in FIG. . Eventually, the hinge piece 59 rotates 90 degrees. FIG. 22 shows the guide rail engaging portion 55 that moves in the twisted connecting section. It can be seen that the guide rail engaging portion 55 rotates about the hinge shaft 52 in correspondence with the twisted guide rail 41.

  FIG. 23 shows a state where the slat 42 is further moved up the connecting section 41b. The guide rail 41 in the connecting section 41b is twisted and then bifurcated. Of the two branched sub-roller guide passages 49, the sub-roller 57 of the upper guide rail engaging portion 55 is guided to the upper sub-roller guide passage 49, and the lower guide rail is guided to the lower sub-roller guide passage 49. The sub roller 57 of the engaging portion 55 is guided. In this way, it is determined which sub-roller guide passage 49 the sub-roller 57 is guided to after branching. The main roller 56 is guided to one of the main roller guide passages 48 that are pulled by the sub-roller 57 at the branch point and branch into two strips.

  Since the guide rail in the connecting section 41b is bent after branching, the sub-roller 57 turns around the main roller support shaft 60 so as to cope with this. FIG. 24 shows a vertical sectional view of the storage section 41c. As shown in the horizontal sectional view of FIG. 18, in the opening section 41a, the rotation shaft of the sub roller 57 and the rotation shaft of the main roller 56 are arranged in a horizontal plane. On the other hand, as shown in FIG. 24, in the storage section 41c, the arm 58 swings its head and the sub roller 57 turns 90 degrees, so that the rotation axis of the sub roller 57 and the rotation axis of the main roller 56 are perpendicular to each other. Placed inside.

  FIG. 25 is a perspective view of the plurality of slats 42 stored in the storage section 41c of the guide rail 41 as viewed from the back side of the shutter device. In the storage section 41c, the upper guide rail engaging portion 55 is guided by the upper guide rail 41, and the lower guide rail engaging portion 55 is guided by the lower guide rail 41. The plurality of slats 42 are arranged in parallel. Further, the hinge piece is opened 90 degrees, and the slat 42 is sandwiched between the pair of guide rails 41.

  Also in this embodiment, the slats of the shutter device may be manually operated or electrically operated. In the case of manual operation, the opening can be opened and closed by raising or lowering each of the plurality of slats 42 one by one. As a method of electrically operating the slat 42, a rack is provided along the guide rail, a pinion meshing with the rack is attached to the bracket, the pinion is rotated by an electric motor, and the bracket is raised or lowered by a rack and pinion mechanism. Can be considered. This electric motor and pinion may be provided in all the brackets 43, or may be provided only in the uppermost and lowermost brackets 43. When the electric motor and pinion are provided only in the uppermost end and the lowermost bracket 43, the drive mechanism attached to the lowermost end bracket 43 pushes up the whole, and when lowering a plurality of slats 42, the uppermost end The drive mechanism attached to the bracket 43 pushes down the whole. It is necessary to synchronize the electric motor regardless of whether the plurality of slats are raised or lowered. In addition, for example, a mechanism in which one end of a chain or a wire is connected to the lowermost slat and the chain or the wire is pulled up or down by an electric motor can be employed.

  26 to 29 show a shutter device according to the fourth embodiment of the present invention. 26 and 27 show perspective views of the shutter device, and FIGS. 28 and 29 show front views of the shutter device. 26 and 28 show a state in which the plurality of slats 72 are moved to the opening section 71a on the lower end side of the guide rail 71 and the opening is closed, and FIGS. 27 and 29 show the plurality of slats 72. Shows a state in which the opening is opened by moving to the storage section 71c on the upper end side of the guide rail 71. In this embodiment, similarly to the shutter device of the third embodiment, when the slat 72 moves to the storage section 71c, the plurality of slats 72 are stored in a state of being arranged in parallel to each other.

  As shown in FIGS. 26 and 27, the shutter device of this embodiment includes a pair of guide rails 71 extending in parallel to each other, a bracket 73 moving along the pair of guide rails 71, and a pair of guide rails 71. And a plurality of slats 72 supported by a plurality of brackets 73. The plurality of slats 72 are not connected to each other.

  As shown in FIG. 28, when the plurality of slats 72 move to the opening section 71 a on the lower end side of the guide rail 71, the guide rail 71 is hidden behind both ends of the slat 72. In the opening section 71 a, the inner method of the pair of guide rails 71 is shorter than the length of the slat 72 in the longitudinal direction. On the other hand, as shown in FIG. 29, when the plurality of slats 72 move to the storage section 71c, the plurality of slats 72 are sandwiched between the pair of guide rails 71. In the storage section 71 c, the inner method of the pair of guide rails 71 is longer than the length of the slat 72 in the length direction. Since the length of the slat 72 in the longitudinal direction is constant, the inner method of the pair of guide rails 71 in the storage section 71c is larger than the inner method of the pair of guide rails 71 in the opening section 71a.

  FIG. 30 shows a side view of the guide rail 71. The guide rail 71 includes an opening section 71a that extends in a straight line in the vertical direction, a connecting section 71b that extends in the vertical direction from the upper end of the opening section 71a, and that is bent and then split into two branches and extends in the horizontal direction. It is divided into a storage section 71c connected to one end of 71b. In the storage section 71c, the guide rail 71 extends in a straight line in the horizontal direction in a bifurcated state. The reason why the guide rail 71 is bifurcated in the storage section 71c is to store the slats 72 in a parallel arrangement.

  FIG. 31 is a sectional view of the guide rail 71. The cross-sectional shape of the guide rail 71 is symmetrical with respect to the center line. In the guide rail 71, a single main roller guide passage 77 extending in the longitudinal direction and two sub-roller guide passages 78 are formed. When viewed from the bracket 73 side, the main roller guide passage 77 is formed at the center and the back side of the guide rail 71, and the two sub-roller guide passages 78 are formed on the left and right sides of the guide rail 41 and at the front side. . A main roller 79 of a bracket 73, which will be described later, is accommodated in the main roller guide passage 77 so as to be capable of rolling, and a sub roller 80 of the bracket 73 is accommodated in the sub roller guide passage 78 so as to be capable of rolling. In the sectional view of the guide rail 71, the rotation axis of the main roller 79 and the rotation axis of the sub roller 80 are orthogonal to each other.

  As described above, the inner method of the pair of guide rails 71 in the storage section 71c is larger than the inner method of the pair of guide rails 71 in the opening section 71a. And the guide rail 71 is arrange | positioned behind the both ends of the slat 72 in the opening part 71a seeing from the front of a shutter apparatus (refer FIG. 28). On the other hand, the guide rail 71 is arrange | positioned in the side part of the longitudinal direction of the slat 72 in the accommodating part area 71c (refer FIG. 29). In order to realize this, in the shutter device of the third embodiment, the guide rail is connected and twisted 90 degrees in the connecting section. However, in the shutter device of this embodiment, the guide rail 71 is connected and the inner method of the pair of guide rails 71 is gradually increased from the opening section 71a toward the storage section 71c without twisting in the section 71b. .

  As shown in FIG. 26, the guide rail 71 branches into two branches after expanding the inner method in the connecting section 71b. As shown in FIG. 30, the one main roller guide passage 77 originally branches into the two main roller guide passages 77 as the guide rail 71 branches. Originally, the two sub-roller guide passages 78 branch from the state of being arranged in parallel into two branches in the connecting section 71b, and extend in a straight line in a state of branching into two in the storage section 71c. Since the guide rail 71 in the connecting section 71b is twisted and branched, the whole is divided into a plurality of divided pieces.

  FIG. 32 is an exploded perspective view of the bracket 73. The bracket 73 includes a bracket main body 81 to which the slat 72 is attached, and two guide rail engaging portions 82 that are coupled to the bracket main body 81 at different positions in the longitudinal direction of the guide rail 71. One of the two guide rail engaging portions 82 is guided to one of the two sub roller guide passages 78, and the other of the two guide rail engaging portions 82 is guided to the other of the two sub roller guide passages 78.

  The guide rail engaging portion 82 includes a disc-shaped rotating body 83 that is rotatably assembled to the bracket body 81, a slide body 84 that is slidably assembled to the rotating body 83 in a uniaxial direction, and an end portion of the slide body 84. A main roller 79 coupled to the main roller support shaft 85 and a sub roller 80 coupled to the main roller support shaft 85 via an L-shaped arm 86 are provided. The main roller 79 rotates about the main roller support shaft 85. The sub roller 80 revolves (revolves) around the main roller support shaft 85. Even if the auxiliary roller 80 is turned by the arm 86, the rotation axis of the auxiliary roller 80 passes through the rotation axis of the main roller 79.

  FIG. 33 shows a detailed view of the slide body 84. The slide body 84 has a semi-cylindrical shape and has a groove 88 having a T-shaped cross section extending in the axial direction. As shown in FIG. 32, the rotating body 83 is formed with a T-shaped projection 89 that fits into the groove 88. The slide body 84 slides in the uniaxial direction while being guided by the protrusions of the rotating body 83.

  As shown in FIG. 32, the bracket main body 81 is processed with a female screw. A through hole 90 is processed at a position of the slat 72 corresponding to the female screw of the bracket body 81. The slat 72 can be attached to the mounting surface of the bracket body 81 by passing the set screw 91 through the through hole 90 of the slat 72 and fitting the set screw 91 into the female screw of the bracket body 81. When removing the slat 72 from the bracket body 81, the set screw 91 may be removed from the bracket body 81. The slat 72 can be attached to and detached from the bracket 73 while the bracket 73 is attached to the guide rail 71. As shown in FIG. 31, the mounting surface 92 of the bracket body 81 protrudes beyond the guide rail 71 to the front side of the shutter device.

  FIG. 34 shows a change in the shape of the bracket 73 that moves the guide rail 71 in the connecting section 71b. The main roller 79 of the guide rail engaging portion 82 is inserted into the main roller guide passage 77 of the guide rail 71, and the sub roller 80 is inserted into one of the two sub roller guide passages 78. As shown in FIG. 34C, when the slat 72 is moving in the opening section 71a of the guide rail 71, the slide body 84 is moving inward (rightward in the figure) of the slat 72. . When the slat 72 rises and enters the connecting section 71b shown in FIG. 34 (B), the inner method of the pair of guide rails 71 becomes gradually longer as described above, and as shown in FIG. 34 (A). The guide rail 71 tends to be separated from the slat 72. Since the main roller 79 and the sub-roller 80 are inserted in the guide rail 71, the slide body 84 slides to the guide rail 71 side (left direction in the figure) by being pulled by the guide rail 71.

  35 and 36 show the movement of the bracket 73 along the guide rail 71. As shown in FIG. 35 (A), when the slat 72 is positioned in the opening section 71a of the guide rail 71, the upper and lower two slide bodies 84 are kept parallel and positioned in the innermost side (left direction in the figure). . As shown in FIG. 35B, when the slat 72 moves to the connecting section 71b, the upper slide body 84 is pulled toward the guide rail 71 by the widened guide rail 71. Since the guide rail 71 is inclined, the slide body 84 that is to be orthogonal to the guide rail 71 is also inclined. The rotation of the slide body 84 is guided by the rotation body 83. As shown in FIG. 36 (A), when the slat 72 is further raised, the upper slide body 84 moves most toward the guide rail 71 and moves to a position just before the branch position. Here, since the guide rail 71 is not inclined, the slide body 84 is also kept horizontal. The lower slide body 84 gradually moves toward the guide rail 71 and tilts according to the tilted rail. As shown in FIG. 36 (B), when the slat 72 is further raised, the main roller 79 of the upper guide rail engaging portion 82 moves upward as the sub roller 80 is guided to the upper sub roller guide passage 78. To the main roller guide passage 77. On the other hand, the main roller 79 of the lower guide rail engaging portion 82 is guided to the lower main roller guide passage 77 as the sub roller 80 is guided to the lower sub roller guide passage 78. As shown in FIG. 36C, when the slat 72 moves to the storage section 71c, the upper guide rail engaging portion 82 is guided to the upper guide rail 71, and the lower guide rail 71 is moved to the lower side. The guide rail engaging portion 82 is guided. Thereby, in the accommodating part area 71c, the several slat 72 maintains parallel.

  FIG. 37 shows a cross-sectional view of the storage section 71 c of the guide rail 71. When the slat 72 moves to the storage section 71c, the slide body 84 slides most toward the guide rail 71, and the two upper and lower slide bodies 84 keep parallel. In the storage section 71c, since the arm 86 swings its head and the sub roller 80 turns 90 degrees, the rotation shaft of the sub roller 80 and the rotation shaft of the main roller 79 are arranged in a vertical plane. Also in this embodiment, the slat 72 of the shutter device may be manually operated or electrically operated.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. For example, in the above-described embodiment, the guide rails are arranged to extend in the vertical direction, and the openings are opened and closed by moving a plurality of slats in the vertical direction (vertical direction). However, the guide rail may be arranged to extend in the horizontal direction, and the opening may be opened and closed by moving a plurality of slats in the horizontal direction (horizontal direction). In this case, it is conceivable that only one guide rail is provided on the upper side without providing a pair. Further, the guide rail may be bent to the back side or the front side as viewed from the front side of the shutter device.
