[Technical Field]

[0001] The present invention relates to a water-stop shutter device that closes an opening to prevent water from flowing through the opening. [Background Art]

[0002] Conventionally, as disclosed for example in Patent Document 1, this type of invention presses a shutter curtain formed of a plurality of vertically stacked panels by an electric pressing device including a power cylinder, a piston rod, etc., and presses the shutter curtain against an immovable part (such as a floor surface or a rail) via watertight rubber to maintain watertightness.

[0003] [Patent Document 1] Japanese Unexamined Patent Application Publication No. 2019-94774 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] By the way, according to the above-described conventional technology, if a power outage occurs while the pressing device is pressing the closed shutter curtain, the pressed state by the pressing device cannot be released, which may make it difficult to open the shutter curtain. To address this issue, a backup power source such as a battery is sometimes provided, but the backup power source itself may fail due to flood damage or the like. [Means for Solving the Problem]

[0005] In view of such problems, one aspect of the present invention has the following configuration. A water-stopping shutter device comprising an opening / closing body that closes in a manner that partitions a space, and a pressing device that generates a pressing force, wherein the closed opening / closing body is pressed against a stationary part by the pressing force of the pressing device, and further comprising a pressing force transmission member that transmits the pressing force of the pressing device, The pressing device generates the pressing force by advancing the movable part of the pressing device in the pressing direction. The pressing force transmission member is equipped with a variable portion that can selectively change its position between a pressable position, which is advanced to enable the transmission of the pressing force, and a retracted position, which is retracted to disable the transmission of the pressing force and enable the opening of the opening / closing body. Furthermore, the variable part can be repositioned from the pressing position to the retracted position while the movable part of the pressing device remains in the advanced position. A water-stopping shutter device characterized by the following features. [Effects of the Invention]

[0006] As described above, the present invention is configured in such a way that the pressing state by the pressing device can be easily released. [Brief explanation of the drawing]

[0008] Next, embodiments of the present invention will be described in detail with reference to the drawings. In this specification, "thickness direction of the opening / closing body" means the thickness direction of the opening / closing body in the closed state. Also, "width direction of the opening / closing body" means a direction that is substantially perpendicular to the opening / closing direction of the opening / closing body, but is not the thickness direction of the opening / closing body. Furthermore, "opening / closing direction of the opening / closing body" refers to the sliding direction in which the opening / closing body partitions or opens up space for its opening and closing operation.

[0009] Furthermore, "outside in the width direction of the opening / closing mechanism" refers to the direction that extends outward along the width direction of the opening / closing mechanism. For example, if the right-hand guide rail is used as the reference point, the outside in the width direction of the opening / closing mechanism would be the rightward direction. Furthermore, "inside in the width direction of the opening / closing mechanism" refers to the direction toward the inside of the opening / closing mechanism along its width direction. For example, if the right-hand guide rail is used as the reference point, the inside in the width direction of the opening / closing mechanism would be the left-hand side.

[0010] Furthermore, "outside in the thickness direction of the opening / closing body" refers to the side that moves away from the center of the opening / closing body's thickness along the thickness direction of the opening / closing body. Furthermore, "inside in the thickness direction of the opening / closing body" refers to the side that is aligned with the thickness direction of the opening / closing body and moves towards the center of the thickness of the opening / closing body.

[0011] The water-stopping shutter device 1 is installed to open and close openings in the building structure, etc., using an opening / closing mechanism 10. This water-stop shutter device 1 includes an opening / closing body 10 which performs a closing operation to partition a space, and is fully closed by abutting its closing direction end against an opposing abutted surface G (e.g., ground, floor, etc.), left and right guide rails 20, 20 that respectively surround both ends of the opening / closing body 10 in the width direction with a concave cross-section and guide the opening / closing body 10 in the closing direction, an opening / closing body storage unit 30 that stores and pays out the opening / closing body 10 on the upper side, pressing devices 40, 50 that generate a pressing force within the opening / closing body storage unit 30, and pressing force transmission members 60, 70 that transmit the pressing force of the pressing devices 40, 50 (see FIG. 1). The opening / closing body 10 in the closed state is pressed against the abutted surface G, which is a stationary portion, and the guide rails 20 by the pressing force of the pressing devices 40, 50.

[0012] The opening / closing body 10 is brought into a fully closed state by stacking a plurality of panels 11, 12 sequentially paid out in the closing direction by the opening / closing body storage unit 30 substantially vertically (see FIG. 2). The plurality of panels 11, 12 are connected in the opening / closing direction by a panel connecting chain 14.

[0013] The panel 11 is a rectangular plate-shaped member elongated in the width direction of the opening / closing body when viewed from the front. This panel 11 is formed of a hard material such as metal into a vertical cross-sectional frame shape having cavities partitioned vertically. The lower end portion of the panel 11 protrudes in a substantially V-shaped vertical cross-section over the entire length in the width direction of the opening / closing body, and a seal portion 16 is integrally provided on the protruding outer surface.

[0014] The seal portion 16 is formed of an elastic material such as rubber or elastomer resin into a V-shaped vertical cross-section along the lower end of the panel 11, and is joined to the lower end portion of the panel 11 over the entire length in the width direction of the opening / closing body.

[0015] Further, at the upper end of the panel 11, a concave portion 11a having a substantially V-groove vertical cross-section is formed over the entire length in the width direction of the opening / closing body so as to fit with the seal portion 16 of the panel 11 (or 12) overlapping above. At both ends in the width direction of the panel 11, support shaft portions 13 are provided so as to protrude in the width direction of the opening / closing body.

[0016] The uppermost panel 12 has a rectangular shape when viewed from the front, which is elongated and continuous in the width direction of the opening / closing body, and its height is smaller than that of panel 11. The dimensions are set appropriately according to the height of the opening that is opened and closed by the opening / closing body 10. Panel 12 is formed in substantially the same manner as panel 11 by drawing or extruding a metal material, resulting in a vertical cross-sectional frame shape with a continuous cavity in the width direction of the opening / closing body. A sealing portion 16 is provided on the lower end of panel 12, similar to panel 11. Furthermore, a support shaft portion 13 is provided on the side of panel 12, similar to panel 11. In addition, a recess 12a is provided on the upper end of panel 12, which extends continuously in the width direction of the opening and closing body.

[0017] Furthermore, if the opening / closing body 10 of the desired height can be constructed using only multiple panels 11, then panel 12 can be omitted. In this case, panel 11 is located at the top, and the upper end of this panel 11 is pressed by the pressing device 40.

[0018] The support shaft portion 13 protrudes outward in the width direction of the opening / closing body from both ends in the width direction of each panel 11, 12 (see Figure 3). This support shaft portion 13 is formed by rotatably supporting a roller on the tip side of a shaft-shaped member that is inserted through the panel connecting chain 14.

[0019] The panel connecting chain 14 is a so-called roller chain used for power transmission, etc., and the support shafts 13 are rotatably inserted at predetermined intervals along its length. This panel connecting chain 14 connects all the panels 11 and 12 in the vertical direction via the support shaft portion 13, and its upper end is attached to a plurality (two in the illustrated example) of sprockets 31a and 31b inside the opening / closing body housing portion 30.

[0020] Furthermore, on the side of each panel 11, a guide shaft portion 15 is provided at the lower end, closer to the interior (see Figures 2 and 3). The guide shaft portion 15 is formed by rotatably supporting a roller on the tip side of a shaft-shaped member that protrudes from the widthwise end of each panel 11. This guide shaft portion 15 engages with and guides the guide member 34 (see Figure 2) inside the opening / closing body storage portion 30 when each panel 11 is stored in the opening / closing body storage portion 30, thereby suppressing runout in the thickness direction of the opening / closing body. Note that this guide shaft portion 15 can be omitted.

[0021] The guide rail 20 is formed in a concave or U-shape in cross-section so as to surround the widthwise end of the opening / closing body 10 when it is closed (see Figure 3). This guide rail 20 is formed in an elongated shape extending from the contact surface G to the opening / closing body storage section 30. Within the guide rail 20, a thickness-direction pressing mechanism 55 that presses the closed opening / closing body 10 from the outdoor side to the indoor side, and a receiving member 21 that receives the opening / closing body 10, which has been pushed by the thickness-direction pressing mechanism 55, from the indoor side, are continuously provided in the vertical direction.

[0022] The thickness-direction pressing mechanism 55 is a device that presses the fully closed opening / closing body 10 toward the indoor side with the downward force of the pressing device 50, which will be described later. This thickness-direction pressing mechanism 55 comprises a contact member 55a that abuts against the outdoor side surface of the opening / closing body 10, a pressing direction changing mechanism 55b that moves the contact member 55a parallel to the indoor side, and an interlocking member 55c that moves up and down in conjunction with the advancement and retraction of the rod 52 (see Figures 3 and 8).

[0023] The pressure direction conversion mechanism 55b is a mechanism that converts vertical force into force in the thickness direction of the opening / closing body. The pressing direction conversion mechanism 55b comprises two link members 55b1 and 55b2 that convert vertical force into the thickness direction of the opening / closing body, and a support member 55b3 that supports these link members 55b1 and 55b2 (see Figure 8).

[0024] The two link members 55b1 and 55b2 are arranged in series in the thickness direction of the opening / closing body, and their central sides are rotatably connected, so that the connection portion protrudes upward, forming a roughly V-shape in side view. One of the link members 55b1 has its outdoor side (left side according to Figure 8) pivotally supported by the support member 55b3 so as to be rotatable. This pivoted portion does not move in the thickness direction of the opening / closing body or in the vertical direction.

[0025] The other link member 55b2 has an indoor-facing portion (right side according to Figure 8) that engages with the support member 55b3 so as to be movable in the thickness direction of the opening / closing body, and is pivotally attached to the contact member 55a so as to be rotatable. This pivot portion does not move in the vertical direction.

[0026] The interlocking member 55c is a long, rod-shaped member that extends in the vertical direction and is engaged with the support member 55b3 so as to be movable in the vertical direction. The upper end of this interlocking member 55c is pivotally attached via a pressing force transmission member 70, which will be described later, and the portion below this pivot point fits into the connection portion of the two link members 55b1 and 55b2. Therefore, when the interlocking member 55c moves in the vertical direction, the connecting portion of the link members 55b1 and 55b2 also moves in the same vertical direction in conjunction with it.

[0027] For example, when the pressing force of the pressing device 50 causes the pressing force transmission member 70 and the interlocking member 55c to move downward, the contact member 55a moves to the outdoor side (to the right in Figure 8) and pushes the opening / closing body 10. Furthermore, as the rod 52 retracts, the pressing force transmission member 70 and the interlocking member 55c move upward, causing the contact member 55a to move towards the indoor side (left side according to Figure 8) and move away from the opening / closing body 10.

[0028] Although not shown in the diagram, a single interlocking member 55c is equipped with multiple pressing direction changing mechanisms 55b spaced apart in the vertical direction.

[0029] Furthermore, the receiving member 21 is a long member that contacts the opening / closing body 10 in the closed state along its entire length in the vertical direction (see Figures 3 and 8). This receiving member 21 is made of an elastic material such as rubber or elastomer resin and elastically contacts the indoor side surface of the opening / closing body 10 to maintain watertightness between the opening / closing body 10 and the guide rail 20.

[0030] Furthermore, the opening / closing body storage section 30 is fixed to the wall surface of the building structure or other object on which the water-stopping shutter device 1 is installed, above the opening that is opened and closed by the opening / closing body 10. As shown in Figure 2, the opening and closing storage section 30 supports a base body 30a having an internal space, sprockets 31a and 31b with a panel connecting chain 14 wrapped around them, a drive mechanism 32 that rotates these sprockets 31a and 31b in both directions, a storage rail 33 that suspends the panels 11 and 12 via a support shaft portion 13 and guides them in the front-rear direction, and a guide member 34 that guides the guide shaft portion 15 on the lower end side of the panel 11 in the horizontal direction.

[0031] The opening / closing storage section 30 rotates sprockets 31a and 31b in one direction using a drive mechanism 32, sequentially extending the multiple panels 11 and 12 that are in the stored state toward the outdoors and closing downwards. The opening / closing storage section 30 also opens the panels 11 and 12 that are in the closed state by rotating sprockets 31a and 31b in the opposite direction using the drive mechanism 32, and stores them toward the indoor side at the top.

[0032] One sprocket 31a is located above the fully closed opening / closing body 10 and closer to the interior. The other sprocket 31b is located above sprocket 31a and closer to the interior. Therefore, when the opening / closing body 10 is closed, the panels 11 and 12 that extend from the opening / closing body storage section 30 are extended diagonally downward towards the outside by the sprockets 31a and 31b. Also, when the opening / closing body 10 is opened, the panels 11 and 12 are moved diagonally upward towards the inside and stored by the sprockets 31a and 31b.

[0033] Furthermore, the drive mechanism 32 includes an electric opening and closing mechanism that operates the chain and sprockets 31a, 31b, etc., using an electric motor, and a manual opening and closing mechanism that operates the chain and sprockets, etc., by manual operation of the operating part 32a. In the illustrated example, the operating part 32a is a chain that can be rotated by pulling it by hand.

[0034] Multiple pressing devices 40 and 50 are mounted on the base 30a of the opening / closing body housing section 30 at intervals in the width direction of the opening / closing body (see Figure 1).

[0035] The pressing device 40 comprises a cylindrical main body 41 fixed to the base 30a of the opening / closing body storage section 30, a rod 42 fitted to the main body 41 so as to move forward relative to it, and a drive source (for example, an electric motor not shown) for moving the rod 42 forward. The drive source drives the rod 42 forward to generate a pressing force, or retracts the rod 42 to release the pressing force.

[0036] Below the multiple pressing devices 40, a pressing force transmission member 60 is provided, which straddles the multiple rods 42 of the pressing devices 40 and is pressed by these rods 42. More specifically, multiple pressing devices 40 are provided on both the left and right sides (two in the example shown in Figure 1). One pressing force transmission member 60 is provided to move up and down by the multiple pressing devices 40 on the left side (two in the illustrated example), and another is provided to move up and down by the multiple pressing devices 40 on the right side (two in the illustrated example) (see Figure 1).

[0037] Each pressing force transmission member 60 is supported by a link mechanism 44 so as the rod 42 moves forward, it follows a predetermined trajectory and approaches the upper end of the opening / closing body 10 (see Figure 7).

[0038] The link mechanism 44 consists of multiple arms that are supported and rotated by a base 30a via brackets or the like. This link mechanism 44 moves the pressing force transmission member 60 closer to or further away from the upper end of the opening / closing body 10 by tracing an arc-shaped trajectory in a side view, while keeping the pressing force transmission member 60 in a substantially horizontal position (see Figure 7).

[0039] The pressing force transmission member 60 supports a variable part 62 in a changeable position below the base 61 which receives the pressing force from the pressing device 40 (see Figure 4). More specifically, the pressing force transmission member 60 comprises a base 61 pivotally supported on the tip side of the rod 42, a variable part 62 provided below the base 61, and a connecting part 63 that connects the variable part 62 to the base 61 so that its position can be changed in the vertical direction.

[0040] The base 61 comprises an angle-shaped base body 61a with horizontal and vertical pieces extending in the width direction of the opening / closing body. This base body 61a is pivotally supported on the tip side of each rod 42, and is also pivotally supported on multiple arms that constitute the link mechanism 44. In Figure 4, reference numeral 61b denotes a pivot bracket that pivotally supports the rod 42 and also pivotally supports a portion of the plurality of arms. Also in Figure 4, reference numeral 61c denotes a pivot bracket that pivotally supports another portion of the plurality of arms.

[0041] The variable portion 62 is a plate-shaped member that extends along the base portion 61 in the width direction of the opening / closing body, and is connected to the base portion 61 by a plurality of connecting portions 63 spaced apart in the width direction of the opening / closing body (see Figure 4). The variable part 62 is supported on the base 61 by a connecting part 63 and a locking / unlocking device 64 so that it can be selectively repositioned between a pressable position (see Figure 5(a)) that enables the transmission of pressing force by the pressing device 40, and a retracted position (see Figure 5(b)) that prevents the transmission of the pressing force and allows the opening / closing body 10 to be opened. When the variable part 62 is in the retracted position, it is no longer located on the opening path of the opening / closing body 10, thereby enabling the opening of the opening / closing body 10.

[0042] Each connecting portion 63 is a bolt-shaped member having a male threaded portion on its outer circumference. The upper end of this connecting portion 63 is loosely inserted into the base body 61a so as to be able to change its position in the vertical direction, and is also locked in place by a locking / unlocking device 64 so as to be able to lock and unlock.

[0043] According to the illustrated example, the engagement / detachment device 64 is a nut-shaped member that screws onto the bolt-shaped connecting portion 63, and is tightened in two ways, one above the other, by sandwiching the horizontal piece of the base body 61a. Furthermore, the lower end of the connecting portion 63 is fixed immovably to the variable portion 62 by welding or the like.

[0044] Therefore, by loosening the two engagement / disengagement devices 64 and moving them vertically, it is possible to change the vertical position of the variable part 62.

[0045] The other pressing device 50, similar to the pressing device 40, comprises a cylindrical main body 51 fixed to a stationary part such as the case of the opening / closing body storage section 30, a rod 52 fitted to the main body 51 so as to move forward relative to it, and a drive source (for example, an electric motor, etc.) for moving the rod 52 forward, generating a pressing force by the forward movement of the rod 52 (see Figure 8). The stroke of the rod 52 in this pressing device 50 is different from that of the pressing device 40. The stroke of the rod 52 is set appropriately according to the amount of movement of the thickness direction pressing mechanism 55, etc.

[0046] The pressing device 50 is provided on the left and right sides of the opening / closing body, with intervals between them, so as to place multiple pressing devices 40 in the width direction of the opening / closing body (see Figure 1). A pressing force transmission member 70 is provided below each pressing device 50 so as to move up and down by the rod 52 of the pressing device 50.

[0047] The pressing force transmission member 70 has the same basic structure as the pressing force transmission member 60, and comprises a base portion 71 pivotally supported on the tip side of the rod 42, a variable portion 72 spaced below the base portion 71, a connecting portion 73 whose upper end is repositionably engaged with the base portion 71 and whose lower end is fixed to the variable portion 72, and a locking / detaching device 74 that locks the upper end of the connecting portion 73 to the base portion 71 in a locking / detaching manner (Figure 6). In Figure 6, reference numeral 71a denotes a pivot bracket that is pivotally supported by the rod 52 and is integrally joined to the base 71.

[0048] In Figure 2, reference numeral 90 denotes a deflection suppression device that moves the movable column 91 towards the center in the width direction of the opening / closing body and presses this movable column 91 against the indoor side surface of the opening / closing body 10 to suppress the deflection of the opening / closing body 10.

[0049] <Effects and Effects> Next, the characteristic effects and advantages of the water-stopping shutter device 1 with the above configuration will be explained in detail.

[0050] With the panels 11 and 12 stored in the opening / closing body storage section 30, when the closing operation by the drive mechanism 32 is started, the multiple panels 11 and 12 are sequentially extended downward from the opening / closing body storage section 30 and stacked on the contact surface G. The opening / closing body 10, consisting of these multiple panels 11 and 12, then comes to a stationary position in the fully closed state shown in Figure 2.

[0051] In this fully closed state, when the pressing devices 40 and 50 are operated, the opening / closing body 10 is pressed vertically and horizontally via the pressing force transmission members 60 and 70. In the initial state, the variable parts 62 and 72 of the pressing force transmission members 60 and 70 are in a pressable position (states as shown in Figures 4 and 6) where pressing force can be transmitted.

[0052] To describe the vertical movement, the pressing device 40 operates based on signals and power from a control circuit (not shown), extending the rod 42 downward relative to the main body 41 (see Figures 7(a) and 7(b)). Then, the pressing force transmission member 60 connected to the front end of the rod 42 rotates in an arc shape by the link mechanism 44, comes into contact with the upper end of the panel 12 (opening / closing body 10), and presses the opening / closing body 10 downward.

[0053] Furthermore, regarding horizontal movement, the pressing device 50 operates based on signals and power from a control circuit (not shown), extending the rod 52 downward relative to the main body 51 (see Figures 8(a) and 8(b)). As a result, the pressing force of the rod 52 causes the pressing force transmission member 70 to move downward, and the contact member 55a moves horizontally and comes into contact with the outdoor side surface of the opening / closing body 10. Furthermore, as this horizontal movement continues, the opening / closing body 10 is pushed inward and pressed against the receiving member 21 (see Figure 8(b)).

[0054] The vertical pressing force from the pressing device 40 and the pressing force transmission member 60 causes the lowest panel 11 to elastically deform by pressing its lower end sealing portion 16 against the contact surface G. Additionally, the sealing portion 16 is also elastically deformed between the vertically adjacent panels 11, 11 (or 12). Furthermore, the horizontal pressing force from the pressing device 50, the pressing force transmission member 70, and the thickness direction pressing mechanism 55, etc., presses each panel 11, 12 of the opening / closing body 10 against the receiving member 21 of the guide rail 20, causing the receiving member 21 to elastically deform. Therefore, watertightness is maintained between the lower end of the opening / closing body 10 and the contact surface G, between the vertically adjacent panels 11, 11 (or 12), and between the opening / closing body 10 and the guide rail 20.

[0055] <Release action> When opening the opening / closing body 10 in the aforementioned pressed state, the pressing devices 40 and 50 can usually be operated in the reverse direction by electrical operation via the control circuit, etc., to release the pressed state. However, if, for example, a power outage occurs and power is not supplied to the pressing devices 40, 50 or the control circuit, making electrical release impossible, the pressing force transmission members 60, 70 are operated manually to contract.

[0056] To describe in detail the procedure for contracting one of the pressing force transmission members 60, first, loosen the upper and lower engaging and disengaging devices 64, 64 that clamp the base body 61a of the base portion 61. Then, move the connecting portion 63 and the variable portion 62 upward (see Figure 5). This movement may be achieved by manually lifting the connecting portion 63 and the variable portion 62, or by loosening the lower locking / unlocking device 64 and then tightening the upper locking / unlocking device 64 to move the variable portion 62 upward.

[0057] Then, after moving the connecting portion 63 and the variable portion 62 by a predetermined amount as described above, the upper and lower locking devices 64, 64 are tightened to fix the connecting portion 63 and the variable portion 62 in place so that they do not descend.

[0058] The procedure for contracting the other pressing force transmission member 70 is substantially the same as in the case of the pressing force transmission member 60: loosen the upper and lower locking / unlocking devices 74, 74 to raise the connecting portion 73 and the variable portion 72, and then tighten the locking / unlocking devices 74, 74.

[0059] These operations allow the opening / closing body 10 to be opened upwards (see Figures 7(c) and 8(c)). To open the opening / closing mechanism 10 while the power is off, the operating unit 32a can be operated manually to move the drive mechanism 32 in the opening direction by hand.

[0060] Therefore, with the water-stopping shutter device 1 configured as described above, the pressing state by the pressing devices 40 and 50 can be easily released manually, and consequently, even in the event of a power outage or other power supply failure, the pressing state by the pressing devices 40 and 50 can be released and the opening / closing body 10 can be opened. For this reason, it is also possible to eliminate the need for a backup power supply to electrically release the pressing devices 40 and 50 in the event of a power outage.

[0061] <Other examples of pressure transmission members> In the water-stopping shutter device 1 of the above embodiment, the pressing force transmission members 60 and 70 can be replaced with other components, such as the pressing force transmission member 80 shown in Figure 9.

[0062] The pressing force transmission member 80 comprises a base 81 pivotally supported on the tip side of the rod 42 of the pressing device 40, a plurality of variable parts 82 provided below the base 81, and a connecting part 83 that connects the variable parts 82 to the base 81 so that their position can be changed in the vertical direction.

[0063] The base 81 comprises an angle-shaped base body 81a with horizontal and vertical pieces extending in the width direction of the opening / closing body. This base body 81a is pivotally supported on the tip side of each rod 42 and is also pivotally supported on a plurality of arms that constitute the link mechanism 44. In Figure 9, reference numerals 81b and 81c indicate pivot brackets having the same structure as those of the pressing force transmission member 60.

[0064] The horizontal piece of the base body 81a is provided with a female screw hole 81a1 into which the male screw portion of the connecting portion 83 is screwed in through.

[0065] The variable portion 82 is provided on the base portion 81 in one or more units (two in the illustrated example). Each variable part 82 is formed in a substantially disc shape and is held in a pressable position at a distance below the base 81.

[0066] The connecting portion 83 is a substantially shaft-shaped member having at least an upper screw portion, and its lower end is fixed immovably to the approximate center of the variable portion 82. The male threaded portion at the upper end of this connecting portion 83 is screwed into the female threaded hole 81a1 of the base portion 81.

[0067] Therefore, with the pressing force transmission member 80 configured as described above, the pressing force of the pressing device 40 can be transmitted when the variable part 82 is advanced downward to a pressing position. To retract the variable part 82, the variable part 82 is rotated by hand, causing the male threaded portion of the connecting part 83 to screw into the female threaded hole 81a1, and the variable part 82 to rise. In the retracted position, the transmission of the pressing force of the pressing device 40 is disabled, and the opening / closing body 10 becomes open. Although not shown in the diagram, the pressing force transmission member 70 can also be replaced with one having substantially the same configuration as the pressing force transmission member 80.

[0068] <Other variations> According to the above embodiment, the opening / closing body 10 is composed of multiple panels 11, but it is also possible to compose the opening / closing body 10 from a single substantially plate-shaped member.

[0069] Furthermore, in the above embodiment, the pressing devices 40 and 50 are mechanisms that generate pressing force using a piston cylinder system. However, other examples of the pressing devices include mechanisms that generate pressing force using a nut-shaped member screwed onto a rotating screw member, mechanisms that generate pressing force using rotating spur gears and rack gears, mechanisms that generate pressing force using a linear motor, and other mechanisms.

[0070] Furthermore, in the above embodiment, the pressing device 40 and the pressing device 50 have different strokes, but in other examples not shown, it is also possible to make the strokes of the two pressing devices 40 and 50 substantially the same by appropriately adjusting the amount of movement of the thickness direction pressing mechanism 55, etc.

[0071] Furthermore, in the above embodiment, the pressing direction conversion mechanism 55b converts the vertical force of the rod 52 into a force in the thickness direction of the opening / closing body by means of a link mechanism or the like. However, as an alternative example, it is also possible to convert the vertical force of the rod 52 into a force in the thickness direction of the opening / closing body by a configuration other than the illustrated example (for example, a rack and pinion mechanism or the like).

[0072] Furthermore, in the above embodiment, the lower ends of the connecting parts 63, 73, and 83 are fixed to the variable part, and the upper ends of these connecting parts are connected to the base in a position that can be changed. However, in another example, the lower ends of the connecting parts are connected to the variable part in a position that can be changed, and the upper ends of these connecting parts are fixed to the base. Of course, in this other example, the connecting parts are configured so as not to interfere with the opening and closing body.

[0073] Furthermore, in the above embodiment, the variable part can be repositioned vertically by screwing the connecting part and the base part together. However, in another example, the connecting part and the base part can be repositioned by a means of engagement and disengagement (not shown), and the variable part is fixed when engaged by the means of engagement and disengagement, and moves vertically when the engagement state by the means of engagement and disengagement is released.

[0074] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without altering the essence of the invention.
