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

[0002] A known prior art waterproof door closes an opening using multiple panels stacked vertically, in which the multiple panels are pressed downwards by a vertical compression means against the floor surface, and the multiple panels are pressed horizontally by a horizontal compression means against a guide rail, thereby maintaining watertightness between the panels and the floor surface, and between the panels and the guide rail (see Patent Document 1).

[0003] [Patent Document 1] JP 2019-94774 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned conventional technology, the horizontal pressing means includes a power cylinder that projects a piston rod downward, and a link mechanism that converts the downward force of the power cylinder into a horizontal force, and the horizontal force presses the multiple panels against the watertight rubber member in the guide rail. This horizontal pressing means converts the vertical force of the power cylinder into a horizontal force using a complex link mechanism, so the structure is complex and there is room for improvement in terms of maintainability, etc. In addition, since the horizontal compression means uses an electrically controlled power cylinder, there is a risk that the water stop operation cannot be performed if there is no electricity due to a power outage during a disaster such as a typhoon or heavy rain.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and its objective is to provide a waterstop shutter device that enables stable waterstop operation during disasters such as typhoons and heavy rains, and also has improved maintainability. [Means for solving the problem]

[0006] In view of the above problems, one aspect of the present invention has the following configuration. a horizontal pressing mechanism that generates a horizontal pressing force, and stops water by pressing the opening / closing body in a closed state against a specified abutment portion with the pressing force of the horizontal pressing mechanism, wherein the horizontal pressing mechanism has an advancing / retreating mechanism consisting of a main body member that is attached and fixed to the guide rails, an operating member that is manually rotatable relative to the main body member, an advancing / retreating member that is horizontally movable relative to the main body member, and a conversion member that converts the rotation of the operating member into a horizontal advancing / retreating movement of the advancing / retreating member, and wherein the horizontal pressing mechanism is configured to be switchable between a pressing state in which the opening / closing body in a closed state is pressed against the specified abutment portion and a pressing release state in which the pressing state is released, by manually operating the operating member. Effect of the Invention

[0007] Since the watertight shutter device of the present invention is configured as described above, it is possible to perform stable watertight operation during disasters such as typhoons and heavy rain, and it is also possible to improve maintainability. [Brief description of the drawings]

[0009] Next, an embodiment of the present invention will be described. Fig. 1 is a schematic front view showing an overall outline of a waterproof shutter device according to the present invention, and Fig. 2 is a schematic side cross-sectional view showing an overall outline of the same waterproof shutter device. As shown in Figure 1, the watertight shutter device 1 comprises an opening / closing body 10 which performs a closing operation to divide a space, left and right guide rails 20 which surround both ends of the opening / closing body 10 in a concave cross section and guide them in the closing direction, a storage section 30 which stores and extends the opening / closing body 10 on the upper side, a closing direction pressing mechanism 40 which presses the opening / closing body 10 in the vertical direction in the fully closed state, and a horizontal direction pressing mechanism 50 which presses the opening / closing body 10 in the horizontal direction in the fully closed state.

[0010] This watertight shutter device 1 is configured to close an opening in a structural element of a building or the like using an opening / closing body 10, and to stop water by pressing the opening / closing body 10 in the closed state against a specified abutting portion using a closing direction pressing mechanism 40 and a horizontal direction pressing mechanism 50.

[0011] (Opening and closing body) First, the configuration of the opening-closing body 10 will be described. As shown in Fig. 2, the opening-closing body 10 is composed of a plurality of panels 11, 12 that are sequentially fed out in the closing direction by a storage section 30. The plurality of panels 11, 12 are connected in the opening-closing direction by a panel connecting chain 14. This opening-closing body 10 is in a fully closed state when the plurality of panels 11, 12 are stacked substantially vertically on a fixed portion G on the lower side (a portion that is abutted against the lower frame, floor surface, ground, etc.). The opening / closing body 10 is opened by moving the vertically stacked panels 11, 12 upward and storing them in the storage section 30.

[0012] Each of the panels 11, 12 is a member having a rectangular plate shape when viewed from the front, which is long in the width direction of the opening / closing body. Each of the panels 11, 12 is formed by pultrusion or extrusion molding a metal material into a frame-like shape in vertical cross section having a cavity partitioned into upper and lower parts.

[0013] The lower end of each of the panels 11, 12 protrudes in a generally 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] Further, at the upper end of each panel 11, a recess 11a having a generally V-groove-like vertical cross section is formed over the entire length in the width direction of the opening / closing body so as to fit into the seal portion 16 of the panel 11 (or 12) overlapping above.

[0015] The seal portion 16 is made of an elastic material such as rubber or elastomer resin and has a V-shaped cross section along the lower end of each panel 11, 12, and is joined to the lower end of each panel 11, 12 over the entire length in the width direction of the opening / closing body.

[0016] The uppermost panel 12 has a rectangular shape when viewed from the front that is continuous and elongated in the width direction of the opening / closing body, and has a smaller height dimension than the panel 11. The dimensions of the uppermost panel 12 are set appropriately depending on the height dimension of the opening that is opened and closed by the opening / closing body 10, etc.

[0017] In addition, support shafts 13 (see FIG. 6) are provided on both ends in the width direction of each of the panels 11, 12 so as to protrude in the width direction of the opening / closing body. The support shafts 13 are formed by rotatably supporting a roller on the tip side of a shaft-shaped member inserted into a panel connecting chain 14.

[0018] The panel connecting chain 14 is a so-called roller chain used for power transmission, etc., and has the support shaft portions 13 inserted therethrough at predetermined intervals in the longitudinal direction. This panel connecting chain 14 connects all of the panels 11, 12 in the vertical direction via the support shaft portion 13, and its upper end side is hung on a sprocket 31 inside the storage portion 30.

[0019] A guide shaft portion 15 (see FIG. 6) is provided on the side surface of each panel 11, closer to the indoor side on the lower end side. This guide shaft portion 15 is configured by supporting a roller rotatably on the tip side of a shaft-shaped member protruding from the end portion of each panel 11 in the width direction. When each panel 11 is stored in the storage section 30, the guide shaft portion 15 engages with and is guided by a guide member 34 in the storage section 30, suppressing vibration in the thickness direction of the opening / closing body (left and right direction in FIG. 2). Note that the guide shaft portion 15 may be omitted.

[0020] (Guide rail) The guide rail 20 is formed to have a concave or U-shaped cross section so as to surround the widthwise end of the opening / closing body 10 in the closed state (see FIG. 6). The guide rail 20 is formed in an elongated shape extending from the immovable portion G to the storage section 30.

[0021] The guide rail 20 is provided with a horizontal pressing mechanism 50 that presses the opening / closing body 10 in the closed state from the outdoor side to the indoor side. Also, a receiving member 21 (contact portion: see Figs. 5 and 6) is provided inside the guide rail 20 to receive the opening / closing body 10 pushed by the horizontal pressing mechanism 50 from the indoor side. This receiving member 21 is an elongated member that is adapted to contact the opening / closing body 10 in the closed state over its entire length in the vertical direction. The receiving member 21 is made of an elastic material such as rubber or elastomer resin, and elastically contacts the indoor side of the opening / closing body 10 to maintain watertightness between the opening / closing body 10 and the guide rail 20.

[0022] (Storage section) The storage section 30 is fixed to a wall surface of a structure or the like on which the water stop shutter device 1 is to be installed, above the opening that is opened and closed by the opening / closing body 10. As shown in Figure 2, this storage section 30 supports a base 30a that is attached and fixed to a wall surface of a main body or the like, a sprocket 31 around which the panel connecting chain 14 is hung, a drive mechanism 32 that rotates the sprocket 31 in both directions, a storage rail 33 that supports the support shaft portions 13 of the panels 11, 12 and suspends the panels 11, 12 to guide them in the front-to-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.

[0023] 2 denotes a deflection suppression device that moves a movable column 25a toward the center in the width direction of the opening / closing body 10 and presses the movable column 25a against the indoor side of the opening / closing body 10 to suppress deflection of the opening / closing body 10.

[0024] The storage unit 30 rotates the sprocket 31 in one direction using the drive mechanism 32, thereby sequentially feeding out the multiple panels 11, 12 in the stored state to the outdoor side and performing a closing operation downward. Also, the storage unit 30 rotates the sprocket 31 in the opposite direction using the drive mechanism 32, thereby performing an opening operation on the panels 11, 12 in the closed state, and stores them on the indoor side at the upper side.

[0025] The drive mechanism 32 also includes an electric opening / closing mechanism (not shown) that uses an electric motor to operate the panel connecting chain 14 and the sprocket 31, etc., and an operating unit 32a as a manual opening / closing mechanism that manually operates the panel connecting chain 14 and the sprocket 31, etc. In the illustrated example, the operating unit 32a is a chain that can be rotated by pulling it by hand.

[0026] (Closing direction pressing mechanism) Next, a description will be given of the closing direction pressing mechanism 40. Fig. 3 shows a schematic side view illustrating the closing direction pressing mechanism in operation. The closing direction pressing mechanism 40 is a device for pressing the opening / closing body 10 in the closed state in the closing direction (up and down direction) of the opening / closing body, and is composed of an electric actuator 41 and an up and down pressing section 42 that presses the opening / closing body 10 in the up and down direction by driving the actuator 41.

[0027] The actuator 41 comprises a cylindrical main body 41a supported by the base 30a, a rod-shaped advancing / retreating portion 41b fitted to the main body 41a so as to be able to move back and forth freely, and a drive portion (e.g., an electric motor and gears, not shown) that advances the advancing / retreating portion 41b, and by driving this drive portion, the advancing / retreating portion 41b is advanced and retreated a predetermined amount relative to the main body 41a.

[0028] A plurality of actuators 41 (two each according to the example in FIG. 1) are provided on each of the left and right halves of the storage section 30. On each of the left and right halves, a vertical pressing portion 42 that presses the opening / closing body 10 from above is provided below the plurality of actuators 41.

[0029] The vertical pressing unit 42 includes a pressing member 42a connected to the advancing and retracting parts 41b of the actuators 41, and a link mechanism 42b that moves the pressing member 42a in an arc shape in a side view. As the advancing and retracting parts 41b advance and retreat, the vertical pressing unit 42 advances and retreats the pressing member 42a in an arc shape, and presses the upper end of the opening / closing body 10 (panel 12) in the closed state downward with the pressing member 42a, thereby pressing the opening / closing body 10 against a fixed part G on the lower side, or releasing this pressed state.

[0030] The pressing member 42a is an angle-shaped member having a horizontal piece and a vertical piece, and is elongated in the width direction of the opening-closing body. The pressing member 42a moves toward and contacts the upper end of the opening-closing body 10 along a circular arc-shaped trajectory in a side view while maintaining its lower surface facing downward, and moves away from the opening-closing body 10.

[0031] The link mechanism 42b is made up of a plurality of arms that are supported by the base 30a via brackets and rotate. The link mechanism 42b moves the pressing member 42a toward or away from the upper end of the opening / closing body 10 while holding the pressing member 42a substantially horizontally, so as to draw an arc-shaped trajectory in a side view.

[0032] (Horizontal pressing mechanism) Next, the horizontal pressing mechanism 50 will be described. Fig. 4 shows a schematic side view of an example of the horizontal pressing mechanism, Fig. 5 shows a schematic side view of the horizontal pressing mechanism in operation, and Fig. 6 shows a schematic plan view of the horizontal pressing mechanism in operation.

[0033] The horizontal pressing mechanism 50 is a device for pressing the opening / closing body 10 in the closed state in the thickness direction (horizontal direction) of the opening / closing body. As shown in Fig. 4, the horizontal pressing mechanism 50 includes a main body member 51, an operating member 52 provided rotatably by manual operation with respect to the main body member 51, an advancing / retreating member 53 provided to be capable of moving forward and backward with respect to the main body member 51, a conversion member 54 for converting the rotational movement of the operating member 52 into the advancing / retreating movement of the advancing / retreating member 53, a connecting member 55 provided at the tip of the advancing / retreating member 53, and a horizontal pressing member 60 provided rotatably on the advancing / retreating member 53 via the connecting member 55.

[0034] The horizontal pressing mechanism 50 is provided at a predetermined height relative to the left and right guide rails 20.

[0035] [Main body] The main body member 51 is made of, for example, a metallic cylindrical member, and supports the operation member 52 so as to be rotatable, and also supports the advancing and retreating member 53 so as to be capable of advancing and retreating. The main body member 51 is attached and fixed to the guide rail 20 by using a fixing means 51a. The fixing means 51a is composed of, for example, a pair of nuts 51a that screw into a thread groove (not shown) formed on the outer circumferential surface of one end of the main body member 51. The main body member 51 is fixed by tightening the pair of nuts 51a so as to sandwich the guide rail 20 with one end side inserted into a mounting hole 20a formed in the guide rail 20.

[0036] The means for attaching the main body member 51 to the guide rail 20 is not limited to this example. For example, the main body member 51 may be attached by an appropriate fastener (for example, a screw, a bolt, a rivet, a bracket, etc.) in a state where one end side of the main body member 51 is inserted into a mounting hole 20a formed in the guide rail 20.

[0037] [Operation section] The operating member 52 is formed, for example, from a metal plate-like member, and is configured as an operating lever having a grip that is held by an operator. The operating member 52 is attached, for example, to one end side of the main body member 51 so as to rotate (swing) via a rotation shaft 52a. The operating member 52 is configured to rotate (swing) by manual operation between, for example, a position in which it lies behind the rear end of the main body member 51 (see Figs. 4 and 5(a)) and a position in which it stands up above the rear end of the main body member 51 (see Fig. 5(b)), and to move the advancing and retreating member 53 forward and backward in the horizontal direction by this rotation (swing).

[0038] [Advance / retreat section] The advancing / retreating member 53 is made of, for example, a metal rod member, and is provided inside the main body member 51 so as to be movable linearly back and forth (horizontally). One end of this advancing / retreating member 53 is connected to the operating member 52 via a conversion member 54, and the other end on the tip side is connected to the horizontal pressing member 60 via a connecting member 55. By operating the operating member 52, the advancing and retreating member 53 advances and retreats between a most retreated position (see FIG. 5(a)) and a most advanced position (see FIG. 5(b)) relative to the main body member 51.

[0039] [Conversion section] The conversion member 54 is made of, for example, a metal plate-shaped link member, and functions to convert the turning motion (rotational motion) of the operating member 52 into the advancing and retreating motion (horizontal motion) of the advancing and retreating member 53. By turning the operating member 52 (operating lever) about the turning shaft 52a, the advancing and retreating member 53 can be moved in the horizontal direction.

[0040] The main body member 51, the operating member 52, the advancing and retreating member 53, and the conversion member 54 constitute an advancing and retreating mechanism that is operated by manual operation by an operator. Since this advancing and retreating mechanism does not require electricity to operate, the water stop operation can be performed by the opening and closing body 10 even when electricity is not supplied due to a power outage during a disaster such as a typhoon or heavy rain. The advancing / retreating mechanism is not limited to the above-mentioned configuration, and may be, for example, a known toggle clamp or other configuration that can convert manual operation of the operating unit into advancing / retreating movement of the advancing / retreating unit.

[0041] [Connection part] The connecting member 55 constitutes a structure that connects the advancing / retreating member 53 and the horizontal pressing member 60. The connecting member 55 is, for example, a rectangular or cylindrical metal block body, and is provided integrally with the tip side of the advancing / retreating member 53. As shown in FIG. 6(a), a bearing hole 55a is provided penetrating the connecting member 55, extending in the horizontal direction approximately perpendicular to the advancing / retreating direction of the advancing / retreating member 53. The horizontal pressing member 60 is supported rotatably relative to the advancing / retreating member 53 by inserting a shaft member 61 through the bearing hole 55a and a shaft hole 60b1 provided in the horizontal pressing member 60.

[0042] In this embodiment, one advance / retreat mechanism is arranged for the horizontal pressing member 60, and the connecting member 55 is arranged at approximately the center of the longitudinal direction of the horizontal pressing member 60 to connect the advance / retreat member 53 and the horizontal pressing member 60.

[0043] [Horizontal pressure part] The horizontal pressing member 60 is made of a long metal member extending in the vertical direction. The horizontal pressing member 60 extends in the vertical direction along the opening / closing body 10 in the closed state, and is formed to a length that can uniformly press each of the panels 11, 12. 6(a), the horizontal pressing member 60 is formed in a U-shaped cross section by a pressing wall 60a facing the opening / closing body 10 and a pair of side walls 60b extending from both side edges of the pressing wall 60a toward the advancing / retracting mechanism part side generally perpendicularly. The horizontal pressing member 60 is disposed in the internal space S defined by the guide rail 20 such that the pressing wall 60a faces the outdoor surface of the opening / closing body 10. The horizontal pressing member 60 can be made of, for example, an extrusion formed from a metal such as aluminum or an aluminum alloy, or a member formed by bending a steel material.

[0044] The pressing wall 60a has a flat pressing surface facing the opening / closing body 10, and is configured to press the opening / closing body 10 with this pressing surface. The pair of side walls 60b form a connecting portion with a connecting member 55 provided at the tip of the advancing / retreating member 53. A shaft hole 60b1 for supporting the connecting member 55 rotatably is formed in the side walls 60b.

[0045] The horizontal pressing member 60 is rotatably supported by the connecting member 55 with the connecting member 55 accommodated in a space defined by the pressing wall 60a and the pair of side walls 60b. Specifically, as shown in Fig. 6(a), a shaft member 61 serving as a support shaft is inserted and supported in a state where a shaft hole 60b1 formed in the pair of side walls 60b of the horizontal pressing member 60 and a bearing hole 55a formed in the connecting member 55 are communicated with each other. The structure of the pivotal support of the horizontal pressing member 60 with respect to the connecting member 55 is not limited to this example. For example, the connecting member 55 may be configured to be pivotally supported by providing a protrusion that is pivotally supported (pivoted) in the shaft hole 60b1 of the horizontal pressing member 60.

[0046] With this configuration, the horizontal pressing member 60 can be switched, by rotating the operating member 52, between a pressing state in which the opening / closing body 10 in the closed state is pressed against the receiving member 21 (the abutting portion) provided inside the guide rail 20, and a pressing release state in which the pressing state is released.

[0047] Next, the manner in which the closing direction pressing mechanism 40 and the horizontal direction pressing mechanism 50 of the water stop shutter device 1 operate will be described. When the panels 11, 12 are stored in the storage section 30 and the closing operation is initiated by the drive mechanism 32 or the operating section 32a, the multiple panels 11, 12 are sequentially pulled downward from the storage section 30 and stacked in the immovable area G on the lower side. The opening / closing body 10 consisting of these multiple panels 11, 12 remains stationary in the fully closed state shown in Fig. 2. In this fully closed state, when the closing direction pressing mechanism 40 operates, the opening / closing body 10 is pressed in the closing direction (vertical direction), and when the horizontal direction pressing mechanism 50 operates, the opening / closing body 10 is pressed in the horizontal direction.

[0048] <Operation of the closing direction pressing mechanism 40> First, a description will be given of the operation in the closing direction by the closing direction pressing mechanism 40. Fig. 3(a) shows a state in which the closing direction pressing mechanism is located in the pressing position, and Fig. 3(b) shows a state in which the closing direction pressing mechanism is located in the pressing position.

[0049] The drive unit (e.g., an electric motor, not shown) of the closing direction pressing mechanism 40 operates by a signal and power from a control circuit (not shown) and extends the advancing / retreating unit 41b downward relative to the main body unit 41a. Then, the vertical pressing unit 42 connected to the front end of the advancing / retreating unit 41b rotates in an arc by the link mechanism 42b and comes into contact with the upper end of the panel 12 (opening / closing body 10), pressing the opening / closing body 10 downward. When the downward pressure on the opening / closing body 10 is to be released, the closing direction pressing mechanism 40 may be operated in the reverse direction by electrical operation via a control circuit or the like to release the pressing state.

[0050] Due to the vertical pressing force of the closing direction pressing mechanism 40, the lowermost panel 11 elastically deforms by pressing the lower end seal portion 16 against the lower immovable portion G. In addition, the seal portion 16 is sandwiched and elastically deformed between the vertically adjacent panels 11, 11 (or 12). Therefore, watertightness is maintained between the lower end of the opening / closing body 10 and the lower immovable portion G, between the vertically adjacent panels 11, 11 (or 12), and between the opening / closing body 10 and the guide rail 20.

[0051] <Operation of the horizontal pressing mechanism 50> Next, a description will be given of the horizontal operation of the horizontal pressing mechanism 50. Figures 5(a) and 6(a) show the horizontal pressing mechanism 50 in the released position, and Figures 5(b) and 6(b) show the horizontal pressing mechanism 50 in the pressed position.

[0052] The advance / retract mechanism of the horizontal pressing mechanism 50 is operated by manually operating (rotating) the operating member 52 in the forward and reverse directions. When the operating member 52 of the horizontal pressing mechanism 50 (see FIG. 5(a)) located in the pressure release position is rotated in the forward direction (clockwise in the figure), this rotational motion is converted into a horizontal advance / retract motion by the conversion member 54, and the advance / retract member 53 is extended in the horizontal direction. Then, the horizontal pressing member 60 rotatably connected via the connecting member 55 provided at the tip of the advance / retract member 53 comes into contact with the outdoor side surface of the opening / closing body 10.

[0053] Furthermore, as the horizontal movement by the horizontal pressing member 60 continues, the opening / closing body 10 is pushed toward the indoor side, and comes into contact with and presses against the receiving member 21 (the abutment portion) provided on the guide rail 20 (see Figure 5 (b)). When releasing the horizontal pressure on the opening / closing body 10, the horizontal pressure mechanism 50 (see FIG. 5(b)) located in the pressing position is manually operated (rotated) in the reverse direction (counterclockwise in the same figure) to operate the horizontal pressure mechanism 50 in the reverse direction and release the pressing state.

[0054] Due to the horizontal pressing force of the horizontal pressing mechanism 50, each panel 11, 12 of the opening / closing body 10 is pressed against the receiving member 21 provided on the guide rail 20, causing the receiving member 21 to elastically deform. Therefore, watertightness is maintained between the opening / closing body 10 and the guide rail 20 (receiving member 21).

[0055] This horizontal pressing mechanism 50 can be operated manually, so even if there is no power supply due to a power outage or the like, the horizontal pressing mechanism 50 can be operated to ensure watertightness between the opening / closing body 10 and the guide rail 20 (receiving member 21). In addition, the horizontal pressing mechanism 50 has a simplified structure in which the horizontal pressing member 60 is axially supported by the advancing / retreating mechanism section consisting of the main body member 51, the operating member 52, the advancing / retreating member 53, and the conversion member 54 via the connecting member 55, thereby reducing the number of parts and improving maintainability.

[0056] (Other variations) Next, another embodiment of the horizontal pressing mechanism of the water stop shutter device 1 according to the present invention will be described with reference to the drawings. Fig. 7 is a schematic side view showing another example of the horizontal pressing mechanism. The horizontal pressing mechanism 50A shown in FIG. 7 is a modified version of the advance / retreat mechanism of the horizontal pressing mechanism 50 shown in FIG. 4 described above. Therefore, the modified parts will be mainly described, and the same components as those of the horizontal pressing mechanism 50 will be given the same reference numerals and redundant descriptions will be omitted.

[0057] 7, the horizontal pressing mechanism 50A is configured such that a plurality of (two in the illustrated example) advancing and retreating mechanisms, each consisting of a main body member 51, an operating member 52, an advancing and retreating member 53, and a conversion member 54, are disposed vertically spaced apart from each other with respect to the horizontal pressing member 60. Specifically, the main body members 51 of each advancing and retreating mechanism are attached and fixed to the guide rail 20 by fixing means 51a, vertically spaced apart from each other, and the advancing and retreating members 53 of each advancing and retreating mechanism are rotatably attached to the horizontal pressing member 60 via connecting members 55.

[0058] According to this horizontal pressing mechanism 50A, the horizontal pressing member 60 is configured to be operable by each of the operating members 52 of the multiple advancing and retreating mechanism parts. Therefore, even if a malfunction occurs in the movement of the opening / closing body 10 due to deterioration over time or the like when moving the opening / closing body 10 toward the receiving member 21 (contact portion), sufficient operating force can be secured by the multiple operating members 52. As a result, the horizontal pressing mechanism 50A can be easily operated to ensure watertightness between the opening / closing body 10 and the guide rail 20 (receiving member 21).

[0059] 7, the operating members 52 of the multiple advancing and retreating mechanisms may be connected by a connecting arm 70 extending in the vertical direction, so that these operating members 52 can be operated in conjunction with each other. In this case, for example, each end of the connecting arm 70 extending in the vertical direction may be pivotally supported by each operating member 52 of each advancing and retreating mechanism, so that the rotational movement of one operating member 52 and the rotational movement of the other operating members 52 are linked (synchronized). With this configuration, multiple advancing and retreating mechanisms operate in conjunction (synchronization), so that the horizontal pressing member 60 can be moved more smoothly to press the opening / closing body 10 against the receiving member 21 (the abutment portion).

[0060] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without departing from the gist of the present invention.
