[0008] Next, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification, the "thickness direction of the opening / closing body" refers to the thickness direction of the opening / closing body in the closed state, and the "width direction of the opening / closing body" refers to a direction that is approximately perpendicular to the opening / closing direction of the opening / closing body, but is not the thickness direction of the opening / closing body. Also, the "opening / closing direction of the opening / closing body" means the direction in which the opening / closing body slides to partition or open the space for opening and closing operations.

[0009] In addition, in this specification, "outside the width direction of the opening / closing body" means the side in the direction toward the outside of the opening / closing body along the width direction of the opening / closing body, and "inside the width direction of the opening / closing body" means the side in the direction toward the inside of the opening / closing body along the width direction of the opening / closing body.

[0010] First Embodiment 1 and 2 show an opening / closing device installation structure A in which an opening / closing device using an example of an opening / closing device pivot support bracket according to the present invention is installed on a wooden frame X.

[0011] The opening and closing device 1 comprises an opening and closing body 10 that opens and closes in the vertical direction, a guide rail 20 that guides the widthwise end of the opening and closing body 10 in the opening and closing direction, and a storage section 30 that extends and stores the opening and closing body 10 on the upper side, and is attached to a wooden body X (see Figures 1 and 2).

[0012] The wooden skeleton X is a hanging wall in a wooden building, and is provided above the opening that is opened and closed by the opening and closing device 1, across the width direction. This wooden structure X (hanging wall) is integrally constructed from a hanging piece of wood x1 extending downward from the top across the width, and a fire-resistant covering material x2 covering the vertical surfaces and bottom end surface on both sides of the hanging piece of wood x1 in the thickness direction.

[0013] The hanging wooden piece x1 is formed from a wooden beam or the like that is long in the width direction, and has a suitable thickness of burning space on the surface side.

[0014] The fire-resistant covering material x2 is a fire-resistant board material, such as gypsum board or calcium silicate board, and is provided in a single layer or multiple layers (in the illustrated example, two layers) covering the vertical surfaces on both sides of the thickness direction and the lower end surface of the hanging wood x1. The surface of the fire-resistant covering material x2 is a substantially vertical immovable surface x21. A fastening piece 32a of a pivot support bracket 32 ​​(described later) is overlapped and fastened to this immovable surface x21.

[0015] The opening / closing body 10 is constructed by connecting multiple slats, each made by bending a horizontally elongated, roughly rectangular metal plate, in the vertical direction to form the opening / closing body main body 11, and connecting a seat plate 12 to the lower end of this opening / closing body main body 11 so that the seat plate 12 can be seated on a fixed surface below (for example, a floor, the ground, a door rail, etc.) (see Figure 1). Other examples of this opening / closing body 10 include a single or multiple panels, or a fire-resistant sheet or net-like material arranged in the opening / closing direction, or an appropriate combination of slats, panels, pipes, sheet or net-like materials, etc.

[0016] The guide rails 20 are provided on both ends of the opening / closing body 10, respectively. Each guide rail 20 is a long member that guides the opening / closing body 10 in the vertical direction by surrounding the end of the opening / closing body 10 in a concave shape. The guide rail 20 is erected substantially vertically on the lower immovable surface, and its upper end is inserted into the storage section 30.

[0017] The storage section 30 includes a winding shaft 31 that winds up and unwinds the opening / closing body 10, support brackets 32, 32 that rotatably support the winding shaft 31 at both ends, a drive mechanism 33 that drives and rotates the winding shaft 31, a cover member 34 that covers the periphery of the opening / closing body 10 wound around the winding shaft 31, a lintel member 35 that stores the seat panel 12 when the opening / closing body 10 is fully open, and a connecting member 36 that integrally connects the left and right support brackets 32, the cover member 34, and the lintel member 35, etc. (see Figure 2).

[0018] The winding shaft 31 is formed in a substantially cylindrical shape and is supported by bearings or the like on both sides of the shaft support brackets 32, 32.

[0019] Each support bracket 32 ​​is integrally provided with a fastening piece 32a that is superimposed on and fastened to the surface (immovable surface x21) of the wooden body X, and a support piece 32b that protrudes from the fastening piece 32a in a direction away from the immovable surface and supports the end side of the winding shaft 31.

[0020] The illustrated pivot bracket 32 ​​is formed by integrally joining a pivot member p having a curved piece p1 on the wooden skeleton X side and a plate-like member q joined to the curved piece p1 by an appropriate joining means (for example, welding, screwing, riveting), etc. Another example of this pivot bracket 32 ​​may be an integral member in which each part is formed by bending.

[0021] The pivotal support member p and the plate-like member q are both made by appropriately processing (for example, pressing or bending) hard metal plate material, and the thickness of the plate-like member q is greater than the thickness of the pivotal support member p. Due to the difference in thickness, the fastening piece 32a is configured to have higher rigidity than the support piece 32b. As another example, the fastening pieces 32a may be made of a material that is more rigid (less likely to deform) than the support pieces 32b.

[0022] The fastening piece 32a is formed in the shape of a vertically long rectangular plate. In the illustrated example, the fastening piece 32a is an integral part formed by overlapping a bent piece p1 with a plate-like member q. The fastening piece 32a is provided with a plurality of (two in the illustrated example) fastening portions 32a1 extending in the vertical direction, and a plurality of (two in the illustrated example) rows of fastening portions 32a1 extending in the horizontal direction.

[0023] According to the illustrated example, the fastening portion 32a1 is a fastening hole provided through the fastening piece 32a, and is fastened to the immovable surface x21 by a fastener 37. The fastening portions 32a1 are provided on one and the other sides of the fastening piece 32a in the width direction, with the support piece 32b disposed therebetween.

[0024] According to the example shown in FIG. 2, four of the fastening portions 32a1 (fastening holes) are provided, located above and below the support piece 32b and on the left and right sides of the support piece 32b. Fasteners 37 (for example, screws, bolts, anchors, etc.) are inserted into the plurality of fastening portions 32a1. The rear end of each fastener 37 is engaged with the fastening piece 32a, and the front end is embedded in the wooden skeleton X and fixed thereto.

[0025] The support piece 32b is formed in a plate shape that is approximately perpendicular to the winding shaft 31. The support piece 32b is located between the fastening portion 32a1 on one side in the width direction of the fastening piece 32a and the fastening portion 32a1 on the other side (in the illustrated example, approximately the center of the width of the fastening piece 32a), and protrudes approximately perpendicularly from the fastening piece 32a. The support piece 32b has a through cutout 32b1 near the center for supporting the winding shaft 31, and curved pieces 32b2, 32b2 at the upper and lower ends for reinforcement.

[0026] The drive mechanism 33 is configured to transmit the rotational force of an opening / closing machine 33a (for example, an electric motor) which is a drive source to the winding shaft 31 by a pulley, a belt, or the like. In the drawing, reference numeral 33b denotes a bracket that supports the opening / closing device 33a, and is connected integrally to the pivot bracket 32.

[0027] The cover member 34 is a member that covers the periphery of the winding shaft 31 in the width direction, and is fixed to a stationary portion of the storage section 30 by a connecting member 36 and a frame (not shown) or the like.

[0028] The lintel member 35 forms an opening through which the opening / closing body 10 passes in the vertical direction. The edge portions of the opening of the lintel member 35 are located on both sides of the seat plate 12 of the opening / closing body 10 in the fully open state, spaced apart in the thickness direction of the opening / closing body (see FIG. 2(a)).

[0029] The connecting member 36 is a long member that spans almost the entire width of the storage section 30, and receives the left and right connecting members 36 from below and connects them together, while also fixing the cover member 34, lintel member 35, etc. together.

[0030] Therefore, according to the opening and closing device installation structure A having the above configuration, it is possible to prevent the support piece 32b from shaking left and right due to earthquakes, etc., and in particular, a gap is formed between the fastening piece 32a and the fixed surface x21, which effectively prevents the entire support bracket 32 ​​from shaking in a rattling manner.

[0031] <Second embodiment> Next, another example of the switchgear installation structure according to the present invention will be described. The opening and closing device installation structure described below is a modified version of the opening and closing device installation structure A, so the modified parts will be mainly described in detail, and similar parts will be given the same symbols and redundant explanations will be omitted.

[0032] The opening and closing device installation structure B shown in FIGS. 4 and 5 is obtained by replacing the pivot bracket 32 ​​in the opening and closing device installation structure A with a pivot bracket 40.

[0033] Two support brackets 40 are provided to support the winding shaft 31 on both sides. Each support bracket 40 has a fastening piece 41 that is superimposed on and fastened to the surface (immovable surface x21) of the wooden body X, and a support piece 42 that protrudes from the fastening piece 41 at one end side in the width direction of the fastening piece 41 and supports the end side of the winding shaft 31. This pivot support bracket 40 is formed by appropriately processing (for example, pressing or bending) a flat plate made of hard metal, so that the fastening piece 41 and the support piece 42 are integrally formed.

[0034] The fastening piece 41 is formed in a vertically long rectangular plate shape and protrudes inward in the width direction of the opening / closing body from the support piece 42. The fastening piece 41 has a plurality of (three in the illustrated example) fastening portions 41a arranged in multiple rows (two rows in the illustrated example) in the horizontal direction, which are fastened to the immovable surface x21 in the vertical direction.

[0035] In the illustrated example, the fastening portion 41a is a fastening hole provided through the fastening piece 41. Of the multiple rows of fastening portions 41a, one row of fastening portions 41a is located near the support piece 42, and the other row of fastening portions 41a is located farther from the support piece 42 than the first row of fastening portions 41a (see Figure 4(b)).

[0036] According to the illustrated example, four of these fastening portions 41a (fastening holes) are provided so as to be positioned on the square sides of the support piece . The fastening members 37 are inserted through the plurality of fastening portions 41a. The rear end of each fastening member 37 is engaged with the fastening piece 41, and the front end is embedded in the wooden frame X and fixed thereto.

[0037] The support piece 42 is formed in a plate shape that is approximately perpendicular to the winding shaft 31, and protrudes approximately perpendicularly from the end of the fastening piece 41 on the outer side in the width direction of the opening / closing body (the right side in FIG. 4(b)). The support piece 42 has a through-shaped notch 42a near the center for supporting the winding shaft 31, and has reinforcing pieces 42b, 42b on the upper and lower end sides. Each reinforcing piece 42b is formed on the upper end side or the lower end side of the support piece 42 by bending or the like.

[0038] Therefore, according to the opening and closing device installation structure B having the above-mentioned configuration, it is possible to prevent the support piece 42 from shaking left and right due to earthquakes, etc., and in particular, by forming a gap between the fastening piece 41 and the fixed surface x21, it is possible to effectively prevent the entire support bracket 40 from shaking and rattling.

[0039] <Axis support bracket 40C> In the above-described opening / closing device installation structure B, the pivot bracket 40 can be replaced with a pivot bracket described below.

[0040] The pivot bracket 40C shown in Figure 6 is the pivot bracket 40 described above, with reinforcing pieces 41b, 41b provided on the upper and lower edges of the fastening piece 41, which protrude along these edges in a direction away from the immovable surface x21.

[0041] Each reinforcing piece 41b is formed by bending or the like on the upper or lower end side of the fastening piece 41. This reinforcing piece 41b extends along the upper or lower side of the fastening piece 41, and its end side is joined to the reinforcing piece 42b of the support piece 42. This joining means may be welding, screwing, riveting, or the like.

[0042] Therefore, by using the support bracket 40C shown in Figure 6, it is possible to obtain substantially the same effects as those of the above-mentioned opening and closing device installation structures A and B, and in addition, the bending deformation of the fastening piece 41 and the support piece 42 can be suppressed by the reinforcing pieces 41b and 42b, respectively, and the lateral movement of the support piece 42 facing the fastening piece 41 can be effectively reduced by the joining of the reinforcing pieces 41b and 42b together.

[0043] <Axis support bracket 40D> A pivot bracket 40D shown in FIG. 7 is the same as the pivot bracket 40C, except that the fastening piece 41 and the support piece 42 are connected by a connecting plate 43 between their upper end edges.

[0044] The connecting plate 43 is made of a hard metal material and has a triangular plate shape in plan view, with one side joined to the reinforcing piece 41b on the upper end side of the fastening piece 41, and the other side joined to the reinforcing piece 42b on the upper end side of the support piece 42. The joining means may be, for example, welding, riveting, screwing, etc.

[0045] Therefore, by using the support bracket 40D shown in Figure 7, it is possible to obtain substantially the same effects as the above-mentioned opening and closing device installation structures A and B, and in particular, it is possible to more effectively reduce the lateral movement of the support piece 42 facing the fastening piece 41.

[0046] <Axis support bracket 40E> 8 is intended to be welded to a metal immovable surface (for example, the surface of a steel plate or steel material, not shown). This pivot bracket 40E has a through-hole 41c (attached portion) for welding in a fastening piece 41 that is fastened to the immovable surface.

[0047] The through-hole 41c is a long hole that penetrates the fastening piece 41 and is elongated in the vertical direction, and is located near the support piece 42 of the fastening piece 41.

[0048] In the support bracket 40E of the above configuration, the inner edge portion 41c1 extending in the vertical direction of the fastening piece 41 and the vertical side portion 41d of the fastening piece 41 that is farther from the support piece 42 function as two rows of fastening portions, and are each welded to a fixed metal surface (not shown). Therefore, with this pivot bracket 40E, a gap is formed between the fastening piece 41 and a fixed surface (not shown), effectively preventing the pivot bracket 40 from rattling or swinging from side to side.

[0049] <Other variations> According to the above embodiment, as a particularly effective aspect, the immovable surface indicated by the symbol x21 is the surface of the fire-resistant covering material x2 constituting the wooden structure X. However, other examples of this immovable surface include the wooden wall surface constituting the wooden structure X, the surface of a metal plate attached to the surface of the wooden structure X, or the wall surface of a reinforced concrete structure.

[0050] According to the above embodiment, the fastening portions are provided in two rows in the horizontal direction, but as another example, the fastening portions may be provided in three or more rows in the horizontal direction.

[0051] According to the support bracket 40C of Figure 6, a particularly preferred embodiment is to provide reinforcing pieces 41b on both the upper and lower edges of the fastening piece 41, but as another example, it is also possible to omit one of these upper and lower reinforcing pieces 41b, 41b.

[0052] According to the support bracket 40C of Figure 6, a particularly preferred embodiment is that the reinforcing piece 41b of the fastening piece 41 is joined to the reinforcing piece 42b of the support piece 42, but as another example, it is also possible to have the reinforcing piece 41b and the reinforcing piece 42b separated from each other.

[0053] According to the support bracket 40D of Figure 7, the connecting plate 43 is provided only between the upper edges of the fastening piece 41 and the support piece 42, but as another example, it is also possible to provide the connecting plate 43 between both the upper and lower edges of the fastening piece 41 and the support piece 42.

[0054] 8, one vertical side portion 41d farther from the support piece 42 is the attachment portion that is fastened to the immovable surface by welding, but as other examples, it is also possible to use an embodiment in which the other vertical side portion closer to the support piece 42 is the attachment portion that is fastened to the immovable surface by welding, or an embodiment in which both vertical side portions are attachment portions that are fastened to the immovable surface by welding. In this case, it is preferable that the through hole 41c serving as the attachment portion be positioned closer to the vertical side portion 41d farther from the support piece 42.

[0055] According to the support bracket 40E of Figure 8, a single through hole 41c is provided as the fastening portion in the fastening piece 41, but as another example, it is also possible to provide a plurality of through holes 41c as the fastening portion in the fastening piece 41 at intervals in the horizontal direction.

[0056] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate within the scope of the present invention.
