BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a shirt apparatus 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 shirt device. FIG. 1 shows a perspective view of the front side of the shirter device, and FIG. 2 shows a perspective view of the rear side of the shirter device. The shirter 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 has an opening section la that extends in a straight line along the left and right edges of the opening of the building, and a connecting section that bends to the back side of the opening at the upper end of the opening section la lb And a storage section lc extending linearly in the horizontal direction from the connecting section lb. The storage section lc and the connecting section lb 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 la, the plurality of slats are arranged so that the surfaces thereof are arranged in one plane. The surface of slat 2 is decorated to suit the interior. The same pattern or color may be applied to each of a plurality of slats 2, or a single pattern may be created when a plurality of slats 2 are combined.

[0029] 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. Slat 2 is a force that requires design rather than functionality.

3 and 4 show an example in which the shirter device is attached to the opening of the wall surface. Fig. 3 shows a cross-sectional view of the shutter device in the horizontal plane, and Fig. 4 shows a cross-sectional view of the shirt device in the vertical plane. As shown in FIG. 3, the shirt device is attached to the recessed wall 4. On both the left and right sides of the opening 4a of the wall surface 4, a step 4b corresponding to the thickness of the shirter device is formed. The height of the step 4b is equal to the height of the shirt device, and the surface of the slat 2 and the wall surface 4 are arranged in the same plane (coplanar). [0031] 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 rectangular 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. Left and right rollers 9 attached to both surfaces of the bracket body 7 are fitted in the two roller guide passages 8. 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 contacts 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. FIG. 5 (A) shows a front view of the bracket body 7, and FIG. 5 (B) shows a side view of the bracket body 7. A piece 11 on the front side of the bracket body 7 is a mounting surface to which the slat 2 is attached. A female screw 11a is added to the front-side piece 11. Three roller mounting female screws 12a, 12b and 12c for mounting the roller 9 are machined on the side surface 12 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 to 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 14b 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 11a of the bracket 3, the slat 2 can be attached to the mounting surface of the bracket 3. When removing the slat 2 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.

[0034] As shown in FIG. 3, the mounting surface 11 of the bracket body 7 to which the slat 2 is attached is It protrudes beyond the guide rail 1 to the front side of the shatter device. When viewed from the front side of the shatter device, both ends 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, the 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 sealer 9 is screwed to the bracket body 7 via the bush 18. A through hole 17a 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. Thus, the force S is used to move the connected bracket 3 along the guide rail 1.

[0036] The slat 2 may be manually operated or electrically operated. If the lowermost one of the plurality of slats 2 is held and lowered by hand, the plurality of slats 2 are lowered together, so that the opening can be closed. On the other hand, if the single slat at the bottom is raised, multiple slats will move up in conjunction with each other, so the opening force S can be increased. When the opening is opened, the plurality of slats move to the storage section lc and are hidden behind the ceiling. Note that the plurality of slats 2 that have risen up to the storage section lc are arranged in one plane in the same manner as when the slats 2 are descending into the opening section la.

[0037] As a method of electrically operating the slat 2, for example, a method of connecting one end of a chain or a 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 also a method in which a rack is provided along the guide rail 1, a pinion that engages 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.

Each of the plurality of brackets 22 is attached with a plurality of slats 23 each having a thin plate shape and elongated 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 set screw 24 for attaching the slats 23 and 23 and the slats 23 to the bracket 22 is the same as that of the shirt device of the first embodiment.

[0040] The guide rail 21 bends to the back side of the opening at the opening section 21a extending linearly in the vertical direction along the left and right edges of the opening of the building, and at the upper end of the opening section 21a. The connecting section 21b and the storage section 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).

FIG. 11 shows a cross-sectional view of the opening in the horizontal plane, and FIG. 12 shows a cross-sectional view of the shirter device in the vertical plane. In this embodiment, as shown in FIG. 11, a guide rail 21 is attached between a pair of opposing side wall surfaces 26a of a recessed wall surface 26. The width between the pair of side wall surfaces 26a is equal to the width of the shirter 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 mounting surface 31 of the bracket 22 so that the surface of the slat 23 is in a plane with the wall surface 26 (so that it is flush).

As shown in FIG. 11, the cross-sectional shape of the guide rail 21 is a U-shaped cross-section (C-shape) from which one side of the quadrangle is removed, and a pair of side portions 28 orthogonal to the bottom portion 27 and the bottom portion 27. It consists of and. 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 comes into contact with one of a pair of opposing side portions 28 of the guide rail 21. 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 shows an exploded perspective view of the bracket 22. The bracket 22 has a pair of left and right guide rails. A bracket main body 32 extending between the rails, and a roller 30 rotatably attached to the left and right ends of the bracket main body 32. The bracket body 32 is formed by projecting a pair of legs 33 from a plate-like base 34. The bracket body 32 is elongated 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.

[0044] 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 in a plane perpendicular to the surface of the slat 23 around the bush 35 with respect to the bracket 22. As a result, the series of connected brackets 22 can be moved along the guide rails 21 (see FIG. 12).

FIG. 14 to FIG. 17 show a shirt device in a third embodiment of the present invention. 14 and 15 are perspective views of the shirter device, and FIGS. 16 and 17 are front views of the shirter 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 openings are 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 over 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. It is the same as the shirt device. However, in the shirter device of this embodiment, unlike the shirter device 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 4 2 is stored in parallel with each other.

The guide rail 41 is arranged in the opening and extends in a straight line in the vertical direction 41a, and is arranged in the ceiling, extends in the vertical direction from the upper end of the opening 4 la, and is bent and then bifurcated. The connecting section 41b that extends in the horizontal direction by being divided into two parts is arranged inside the ceiling and connected to one end of the connecting section 41b. And the storage section 41c. 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 parallel arrangement.

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 shirter device (see FIG. 16). On the other hand, the guide rail 41 is arranged on the lateral side of the slat 42 in the storage section 41c (see 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 arranged behind the slat 42 is twisted to gradually increase the longitudinal length of the slat 42 as shown in FIGS. 21 (B) and (A). It will be located to the side of the direction. 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 wheel 52 of the bracket 43 attached to the back of the slat 42.

[0051] As shown in FIG. 20, the guide rail 41 is bifurcated after being twisted. Originally, one main roller guide passage 48 branches into two main roller guide passages 48a and 48b as the guide rail 41 branches. Originally, the two sub-roller guide passages 49 extend in a straight line with a state force aligned in parallel, branching into two branches in the connecting section 41b and branching into two branches in the storage 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 in 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 fastener 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 secondary roller guide passages 49, and the other of the two guide rail engaging portions 55 is the two secondary roller guide passages. You will be guided to the other side of Road 49. Of the two guide rails 41 branched 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 41 is engaged by the lower guide rail 41. Joint part 55 is guided.

[0053] The guide rail engaging portion 55 is coupled to the bracket body 54 via a hinge. The guide rail engaging portion 55 includes 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 about the main roller support shaft 60. Ij The ij roller 57 is connected to the main roller support shaft 60 via an L-shaped arm 58 and revolves around the main roller support shaft 60.

[0054] 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. The slat 42 can be attached to the mounting surface 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. 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 shirt device.

[0055] 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, as shown in FIG. 21, 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. . Eventually, the hinge piece 59 rotates 90 degrees. FIG. 22 shows the guide rail engaging portion 55 moving in the twisted connecting section. Corresponding to the twisted guide rail 41, the guide rail engaging portion 55 rotates about the hinge shaft 52.

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 is guided to the lower sub-roller guide passage 49. The auxiliary roller 57 of the rail engaging portion 55 is guided. In this way, 畐 ij roller 57 is guided to which sub-roller guide passage 49 after branching. It is decided whether it will be done. 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 branching point and branched into two strips.

[0057] Since the guide rail in the connecting section 41b is bent after the branching, the ij roller 57 turns around the main roller support shaft 60 so as to be able 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 IJ 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 secondary mouth roller 57 rotates 90 degrees, so the rotational axis of the secondary roller 57 and the rotational axis of the main roller 56 Are placed in the vertical plane.

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. In addition, the hinge piece is opened 90 degrees, and the slat 42 is sandwiched between the pair of guide rails 41.

[0059] Also in this embodiment, the slats of the shirter device may be operated manually or electrically. In the case of manual operation, the opening can be opened and closed by holding each one of the plurality of slats 42 and raising or lowering. As a method of operating the slat 42 electrically, a rack is provided along the guide rail, a pinion that engages with the rack is attached to the bracket, the pinion is rotated by the electric motor, and the bracket is raised or lowered by the rack and pinion mechanism. A method is conceivable. This electric motor pinion may be provided in all the brackets 43, or may be provided only in the brackets 43 at the uppermost end and the lowermost end. When the electric motor pinion is installed only in the uppermost and lowermost brackets 43, the drive mechanism attached to the lowermost bracket 43 pushes up the whole, and when lowering multiple slats 42, The drive mechanism attached to the uppermost bracket 43 will push down the whole. It is necessary to synchronize the electric motor regardless of whether the slats are raised or lowered. In addition, for example, one end of a chain or wire is connected to the lowermost slat, and the chain or wire is connected by an electric motor. It is also possible to adopt a mechanism that raises or lowers.

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 7 lc, the plurality of slats 72 are sandwiched between the pair of guide rails 71. In the storage section 71c, 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 is bent and then split into two branches and extends in the horizontal direction. The storage section 71c is connected to one end of the connection section 71b. In the storage section 71c, the guide rail 71 extends in a straight line in the horizontal direction in a bifurcated state. In the storage section 71c, the guide rail 71 is bifurcated because the slats 72 are arranged in parallel. It is for storing with.

FIG. 31 shows a cross-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 at the left and right sides of the guide rail 41 and 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 an auxiliary roller 80 of the bracket 73 is accommodated in the ij roller guide passage 78 so as to be capable of rolling. In the cross-sectional view of the guide rail 71, the rotation axis of the main roller 79 and the rotation axis of the auxiliary roller 80 are perpendicular to each other!

[0065] 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 shirt apparatus (refer FIG. 28). On the other hand, the guide rail 71 is disposed on the lateral side of the slat 72 in the storage section 71c (see FIG. 29). In order to realize this, the guide rail of the third embodiment is twisted 90 degrees in the connecting section. However, in the shatter device of this embodiment, the guide rail 71 is connected, and in the section 71b, the inner method of the pair of guide rails 71 is gradually increased from the opening section 71a without twisting toward the storage section 71c. .

[0066] 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 to the two main roller guide passages 77 as the guide rail 71 branches. Originally, the two sub-roller guide passages 78 are bifurcated in the connecting section 71b from the state of being arranged in parallel, and extend linearly in a state of being bifurcated in the storage section 71c! Since the guide rail 71 in the connecting section 7 lb is twisted and branched, the whole is divided into a plurality of divided pieces.
