[0008] Next, an embodiment of the present invention will be described in detail with reference to the drawings. First Embodiment The opening and closing device 1 opens and closes an opening A1 in a skeleton A of a building or the like, and in the illustrated example, constitutes a waterproof shutter device that closes the opening A1 in a substantially watertight manner. This opening and closing device 1 comprises an upper part 10 attached to a wall surface A2 above the opening A1 in the main body A and protruding approximately horizontally from this wall surface A2, a suspension member 15 that suspends the protruding part of the upper part 10 from the wall surface A2 and is connected to the top surface A3 which is a fixed part of the main body A, an opening and closing body 20 that is unreeled from the upper part 10 and performs a closing operation downward, a guide rail 30 that guides the widthwise end of the opening and closing body 20 in the vertical direction, and a center pillar 40 that supports the opening and closing body 20 from the downstream side (indoor side) when the opening and closing body 20 in the closed state is subjected to water pressure.

[0009] According to the illustrated example, the upper portion 10 is a component located above the guide rail 30. The upper portion 10 does not include the opening / closing body 20, the guide rail 30, or the center post 40. This upper portion 10 includes a storage case 11 that surrounds the opening / closing body 20 in the stored state, and an opening / closing body storage device 12 that pulls the opening / closing body 20 upward and moves it in a direction away from the wall surface A2 (leftward in Figure 4).

[0010] The storage case 11 is attached to a wall surface A2 of the body A and protrudes substantially horizontally from the wall surface A2. The storage case 11 closes the opening A1 by extending the opening / closing body 20 downward. The portion of the storage case 11 that protrudes from the wall surface A2 is hung from a fixed portion of the body A (top surface A3 in the illustrated example) by a hanging member 15, which will be described later.

[0011] This storage case 11 is configured in an approximately rectangular parallelepiped shape and integrally comprises plate-like members 11a, 11b, 11c, and 11d that cover the opening / closing body 20 in the stored state, a support frame 11e that supports these plate-like members, and a fixing bracket 11f that connects and fixes these plate-like members and support frame to the wall surface A2 (see Figures 2 and 3).

[0012] The plurality of plate-like members 11a, 11b, 11c, and 11d are configured in a generally box-like shape that is elongated in the width direction of the opening A1. Of these plurality of plate-like members, two plate-like members 11a are provided so as to cover the left and right side surfaces of the storage case 11, respectively.

[0013] Plate-like member 11b is located on the end face of the portion of storage case 11 that protrudes from wall surface A2, and is detachably attached to support frame 11e with fasteners such as screws or bolts. By removing plate-like member 11b, an opening can be formed on the indoor side of storage case 11, and this opening makes it possible to perform maintenance work such as inspection and repair inside storage case 11.

[0014] The plate-like member 11c is located on the upper end surface of the storage case 11, covers the opening / closing body storage device 12 and the opening / closing body 20 in the stored state, and is fixed to the support frame 11e. This plate-like member 11c is formed in a plate shape without any notches in order to maintain strength, etc. (see FIG. 3). The lower end of the hanging member 15 is connected to the upper surface of the plate-like member 11c, and the pivot bracket 12b1 is connected to the lower surface of the plate-like member 11c via a support member 12b2.

[0015] The plate-like member 11d is located on the lower end surface of the storage case 11, and covers the underside of the opening / closing body storage device 12 and the opening / closing body 20 in the stored state, leaving only the insertion portions of the opening / closing body 20, guide rail 30, center column 40, etc., and is fixed to the support frame 11e.

[0016] The support frame 11e includes a plurality of frame members 11e1 (angle members in the illustrated example) made of hard metal, arranged along each side of the rectangular parallelepiped storage case 11. Adjacent ends of these frame members 11e1 are integrally connected by joining means such as welding.

[0017] This support frame 11e supports each side of the plate-like members 11a, 11b, 11c, and 11d from the inside by frame members 11e1 (see FIGS. 2 and 3). The frame material 11e1 and each of the plate-like members are connected by appropriate connecting means (for example, screws, rivets, welding, etc.).

[0018] The fixing bracket 11f is a member that connects the support frame 11e to the wall surface A2. The fixing bracket 11f is fixed integrally to the end of the support frame 11e that is closer to the wall surface A2, and is fixed to the wall surface A2 with fasteners such as anchors (see FIG. 2). This fixed bracket 11f may be configured in such a manner that a plurality of vertically elongated frame members (e.g., L-angles) are arranged at intervals in the width direction of the storage case 11, or that the frame members are configured in a rectangular shape that follows the back surface of the storage case 11 (the surface on the wall surface A2 side).

[0019] The opening / closing body storage device 12 comprises a lifting rotation section 12a that lifts the opening / closing body 20, a driving rotation section 12b that drives and rotates the lifting rotation section 12a in the separation direction (left direction in Figure 2) away from the wall surface A2, a driving source 12c that rotates the driving rotation section 12b, and a rail 12d that suspends the opening / closing body 20 and guides it in the separation direction, and is connected to the upper inner surface of the storage case 11. The opening / closing body storage device 12 has a fixed portion (a pivot bracket 12b1 in the illustrated example) connected to the plate-like member 11c of the storage case 11.

[0020] The lifting rotation parts 12a are rotatably supported sprockets, and are provided above the guide rails 30 on both ends of the storage case 11 in the width direction. This lifting rotation part 12a has a connecting member 22 that constitutes the opening / closing body 20 wrapped around it, and by rotating in one direction, it lifts up the connecting member 22 and guides it toward the driving rotation part 12b, and by rotating in the opposite direction, it extends the connecting member 22 downward.

[0021] The driving rotation part 12b is a sprocket that rotates by the rotational force of the driving source 12c. The rotational force of the driving rotation part 12b is transmitted to the lifting rotation part 12a by a power transmission member 12e such as a chain. The drive rotation part 12b is rotatably supported by a substantially plate-shaped support bracket 12b1 that intersects with the direction of its rotation axis, a bearing (not shown), etc. The support bracket 12b1 is connected to the lower surface of the plate-shaped member 11c of the storage case 11 via a vertically long support member 12b2, etc.

[0022] In the illustrated example, the support member 12b2 is an angle member made of hard metal that extends in the vertical direction. The support member 12b2 is disposed in the storage case 11 in a substantially linear manner relative to the hanging member 15. The lower end of this support member 12b2 is connected to the upper end of the pivot bracket 12b1 via a similar angle bar extending in a substantially horizontal direction. The upper end of the support member 12b2 is also connected to the lower surface of the plate-like member 11c via another angle bar extending in a substantially horizontal direction. These connections may be made by welding, or may be made by fasteners such as screws, bolts, or rivets.

[0023] Driving source 12c is a rotary driving source such as an electric motor. Driving source 12c is supported by a substantially plate-shaped bracket 12c1. Bracket 12c1 is fixed to a pivot bracket 12b1 that supports driving rotation unit 12b. Bracket 12c1 and pivot bracket 12b1 may be an integrated member.

[0024] The reference numeral 12f denotes a beam-like member that is fixed to the lower end side inside the storage case 11 and continues in the width direction. This beam-like member 12f supports the pivot bracket 12b1, the lifting rotation part 12a, etc. via sheet metal members and the like (not shown).

[0025] The hanging member 15 hangs and holds the connection portion of the storage case 11 with the opening / closing body storage device 12 (specifically, the pivot bracket 12b1) on the separating direction side (left direction side in FIG. 2) away from the wall surface A2. The hanging member 15 is a long member extending in the vertical direction, and in the illustrated example, is made of an angle bar made of hard metal. The lower end of the hanging member 15 is connected to the upper surface of the plate-like member 11c via a substantially horizontal angle bar, and the upper end of the hanging member 15 is connected to the top surface A3 of the frame A via a substantially horizontal angle bar.

[0026] The opening / closing body 20 comprises a plurality of panels 21 that are extended downward from the upper portion 10 (storage case 11) and stacked on a lower immovable surface A4 (e.g., a floor surface, etc.), and connecting members 22 that connect these panels 21.

[0027] Each panel 21 is a plate-like member that is long in the width direction of the opening / closing body and has a rectangular shape when viewed from the front. A seal portion 21a is provided at the lower end of each panel 21 and is pressed against the lower portion (the lower panel 21, the floor surface, etc.) in a watertight manner. Additionally, roller members 21b are supported on the upper side of the side surfaces of each panel 21 so as to roll on rails 12d.

[0028] The connecting members 22 are well-known roller chains and are respectively disposed on both sides of the opening-closing body 20. A plurality of panels 21 constituting the opening-closing body 20 are fastened to each connecting member 22 at intervals in the longitudinal direction. When the lifting and rotating portion 12a is rotated in one direction, the connecting member 22 looped around the lifting and rotating portion 12a moves upward, and the plurality of panels 21 perform an opening operation. Furthermore, when the lifting rotation portion 12a is rotated in the reverse direction, the connecting member 22 moves downward, and the plurality of panels 21 perform a closing operation, and are stacked one after another on the lower stationary surface A4.

[0029] The guide rail 30 has a vertical recessed groove 31 that fits into the widthwise end of the opening / closing body 20, and this recessed groove 31 guides the opening / closing body 20 in a straight line in the vertical direction during opening and closing operations.

[0030] A plurality of center posts 40 (two in the illustrated example) are provided so as to be housed on the guide rail 30 side. The upper end of each center pillar 40 is suspended via a hoisting wheel so as to be movable in the width direction relative to the storage case 11. When the opening / closing body 20 is fully closed, each center pillar 40 is moved toward the center of the opening / closing body 20 and comes close to or into contact with the indoor side of the opening / closing body 20, thereby preventing the opening / closing body 20 from bending toward the indoor side due to water pressure, etc.

[0031] <Action and effect> According to the opening and closing device 1 having the above-described configuration, the upper portion 10 is suspended by the suspension member 15 on the side away from the wall surface A2 (to the left in Figure 2) from the opening and closing body 20 in the stored state and the pivot point P of the drive rotating portion 12b. Therefore, it is possible to effectively prevent the upper portion 10 (storage case 11) from being deflected by the weight of the opening / closing body 20, the opening / closing body storage device 12, and the like.

[0032] <Second embodiment> In the opening and closing device 2 shown in FIG. 4, the position at which the suspending member 15 suspends the storage case 11 is shifted further toward the separation direction (to the left in the drawing). The lower end of the hanging member 15 is connected to the frame member 11e1 of the support frame 11e on the side closer to the driving source 12c in the separation direction, and the upper end of the pivot support bracket 12b1 is connected to the same frame member 11e1 via the frame member 11e1 of the support member 12b2. According to this opening and closing device 2, it is possible to more effectively prevent the upper portion 10 (storage case 11) from being deflected by the weight of the opening and closing body 20, the opening and closing body storage device 12, and the like.

[0033] <Other variations> According to the embodiment shown in FIG. 2, the pivot bracket 12b1 is connected to the top plate-like member 11c via the support member 12b2, but other examples include a configuration in which the pivot bracket 12b1 is directly attached to the plate-like member 11c, a configuration in which the pivot bracket 12b1 is connected to another plate-like member, or a configuration in which the pivot bracket 12b1 is connected to the support frame 11e.

[0034] According to the above embodiment, the upper end of the hanging member 15 is connected to the top surface A3 of the main body A, but as another example, it is also possible to connect the upper end of the hanging member 15 to an immovable part of the main body A other than the top surface A3 (for example, a beam material not shown).

[0035] In the above embodiment, a two-axis shutter device was configured having two rotating parts, a lifting rotating part 12a and a driving rotating part 12b. However, as another example, in a single-axis shutter device in which the shutter curtain is wound up on a single rotating part (winding shaft), it is also possible to hang the upper part (for example, a storage case or a support bracket, etc.) by a hanging member 15.
