Description

[Technical field]

[0001] The present invention relates to an opening and closing device that partitions and closes a space using an opening and closing body. [Background technology]

[0002] Conventional inventions of this type, as described in Patent Document 1, for example, include a water stop shutter device that comprises a number of panels that extend downward from a lid opening below a storage section, guide rails that guide the multiple panels downward at their widthwise ends, and a movable pillar that moves from the widthwise end side of the opening / closing body to the center when the multiple panels are stacked on the floor in a closed state, and approaches the multiple panels from the downstream side, and in which the multiple panels in the closed state block the flow of water. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2022-180953 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, according to the above-mentioned conventional technology, when the multiple panels are stored in the upper storage section in the open state, openings, irregularities, etc. are formed on the wall surfaces on both sides in the width direction of the opening / closing body by components that function on the lateral side, such as the guide rails and the movable columns in the stored state. As a result, there is a risk that the openings and unevenness will mar the aesthetic appearance of the wall surface, that passersby may come into contact with the openings or unevenness, or that wind and rain may enter the openings. [Means for solving the problem]

[0005] In view of the above problems, one aspect of the present invention has the following configuration. An opening and closing device comprising: an opening and closing body that is extended downward and performs a closing operation to partition a space; a side functional part that forms and functions an opening on the side of the closing path of the opening and closing body; and a side opening and closing member that covers the side functional part in an openable and closable manner. Effect of the Invention

[0006] Since the present invention is configured as described above, it is possible to reduce openings and irregularities formed on the side wall surfaces. [Brief description of the drawings]

[Figure 12] 13 is a cross-sectional view showing another example of the installation structure of the side opening / closing member. FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Next, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification, the term "thickness direction of the opening / closing body" refers to the thickness direction of the opening / closing body in a closed state, and the term "width direction of the opening / closing body" refers to 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. Further, the "opening / closing direction of the opening / closing body" refers to the sliding direction in which the opening / closing body divides or opens the space for the opening / closing operation.

[0009] In addition, the term "outer side in the width direction of the opening / closing body" refers to the direction toward the outside of the opening / closing body along the width direction of the opening / closing body. For example, when the guide rail on the right side is used as a reference, the outer side in the width direction of the opening / closing body is the right side. In addition, the term "inner side in the width direction of the opening / closing body" refers to the direction toward the inside of the opening / closing body along the width direction of the opening / closing body. For example, when the guide rail on the right side is used as a reference, the inner side in the width direction of the opening / closing body is the left side.

[0010] Additionally, the term "outside in the thickness direction of the opening / closing body" refers to the side in the direction away from the center of the thickness of the opening / closing body along the thickness direction of the opening / closing body. Additionally, the term "inner side in the thickness direction of the opening / closing body" refers to the side toward the center of the thickness of the opening / closing body along the thickness direction of the opening / closing body.

[0011] In addition, the "upstream side" and the "downstream side" refer to the upstream side and downstream side of the assumed flow direction, and in the illustrated example, the outdoor side is the upstream side and the indoor side is the downstream side. As another example, it is also possible to configure the outdoor side as the downstream side and the indoor side as the upstream side.

[0012] <First embodiment> The opening / closing device A comprises an opening / closing body 10 that is extended downward from a top opening 2 and performs a closing operation to divide a space, a lateral functional unit 30 that forms and functions an opening (in the illustrated example, a guide opening 31a and a movable center column storage opening 32a) on the lateral side of the closing path of the opening / closing body 10, an opening / closing body storage unit 40 that stores the opening / closing body 10 above it, a top opening 2 that extends downward the opening / closing body 10 sent out from the opening / closing body storage unit 40, a top opening member 50 that opens and closes the top opening 2, and a side opening member 60 that covers the side functional unit 30 in an openable and closable manner (see Figures 1 to 9). In addition, this opening / closing device A is equipped with a movable center pillar 20 that approaches or comes into contact with the opening / closing body 10 from the downstream side when the opening / closing device is in the closed state, and forms a water-stopping shutter device that uses the opening / closing body 10 to prevent water from flowing through the main body passage 1a during floods, etc. (see Figures 1 and 5).

[0013] The ceiling opening 2 is configured by reinforcing an opening formed in the structural ceiling portion 1b with a lintel member 2a. The top opening 2 is formed in a horizontally elongated rectangular shape that allows the opening / closing body 10 and the movable center post 20 to pass through. That is, the opening / closing body 10 performs an opening operation in the vertical direction by passing through the top opening 2. Also, the movable center post 20 moves in the width direction of the opening / closing body by inserting its upper end portion into the top opening 2.

[0014] The lintel members 2a are provided at positions along the inner edge of the upstream side (outdoor side) of the top opening 2, and at positions along the inner edge of the downstream side (indoor side) of the top opening 2. Each lintel member 2a is fixed to an immovable portion (for example, a steel material supporting the opening / closing body storage portion 40, a beam member, etc.) above the skeleton ceiling portion 1b.

[0015] The opening / closing body 10 comprises a plurality of panels 11, 12 which are successively fed out from the opening / closing body storage section 40, and a flexible, long panel connecting member 13 which connects these panels 11, 12. In the drawing, reference numeral 11 denotes the lowermost panel, and reference numeral 12 denotes the other panels.

[0016] 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. The panels 11, 12 are 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. The lower ends of the panels 11, 12 protrude in a generally V-shaped vertical cross section over the entire length in the width direction of the opening / closing body, and the protruding outer surfaces are covered with a seal portion made of an elastic material (such as rubber or elastomer resin).

[0017] The lowermost panel 11 is pressed against the lower frame member 3 in a watertight manner. The lower frame member 3 is a long member that continues across the width of the body passage 1a and is provided approximately flush with the floor surface of the body passage 1a. This lower frame member 3 may also be called a door sill or the like.

[0018] The other panel 12 fits watertightly against the upper end of the approximately V-shaped concave vertical cross section of the lower panel 11 (or 12).

[0019] A support shaft portion 12a and a guide shaft portion 12b are provided on both ends in the lateral direction of each panel 12 so as to protrude in the width direction of the opening / closing body.

[0020] The support shaft portion 12 a rotatably supports a roller for rolling on the storage rail 43 of the opening / closing body storage portion 40 at the tip side of a shaft-shaped member inserted into the panel connecting member 13 of each panel 12 .

[0021] The guide shaft portion 12b is configured to rotatably support a roller on the tip side of a shaft-shaped member protruding from an end portion in the width direction of each panel 12. When each panel 12 is stored in the opening / closing body storage section 40, this guide shaft section 12b engages with and is guided by a guide member 44 (see FIG. 4) in the opening / closing body storage section 40, thereby suppressing vibration in the opening / closing body thickness direction.

[0022] The panel connecting member 13 is a so-called roller chain used for power transmission or the like, and has the support shaft portions 12a inserted therethrough at predetermined intervals in the longitudinal direction. The panel connecting member 13 connects all of the panels 11, 12 in the vertical direction via a support shaft portion 12a, and its upper end side is hooked onto a sprocket 41 in the opening / closing body storage portion 40.

[0023] The lateral functional part 30 is located on the lateral side of the closing path of the opening / closing body 10 and is equipped with a guide rail 31 that inserts the opening / closing body 10 into the guide opening 31a to guide it in the closing direction, and a movable center column storage part 32 upstream of the guide rail 31 that stores the movable center column 20 inserted into the movable center column storage opening 32a (see Figure 9). This lateral functional portion 30 is provided in the space between the body wall portion 1d and the inner wall material 1e, and the guide opening 31a and the movable center pillar storage opening 32a are disposed substantially flush with the surface of the inner wall material 1e.

[0024] The wall portion 1d of the framework is a wall constituting a building or the like in which the opening and closing device A is to be installed. The inner wall material 1e is a plate-like member provided approximately parallel to the structural wall portion 1d at a distance therefrom, and is made of, for example, a plaster board, a decorative board, or other building material.

[0025] The guide rail 31 is formed with a concave cross section that vertically covers the widthwise end of the opening / closing body 10 in the closed state. An opening on the inner side of the guide rail 31 in the widthwise direction of the opening / closing body (the left side in FIG. 9) functions as a guide opening 31a through which the widthwise end of the opening / closing body 10 is inserted in the vertical direction. Provided inside this guide rail 31 are a thickness direction pressing mechanism 31d that presses the opening / closing body 10 in the closed state from the downstream side to the upstream side, and a receiving member 31e that receives the opening / closing body 10 from the upstream side as it is pressed by this thickness direction pressing mechanism 31d (see Figure 9). For the thickness direction pressing mechanism 31d and the receiving member 31e, those described in Patent Document 1, for example, can be used.

[0026] The guide rail 31 has its upper end inserted through the top opening 2 and its lower end in contact with the lower frame member 3 and the frame floor 1c, etc., and is fixed to an immovable portion such as the frame wall 1d.

[0027] The movable center post 20 is configured to move from a storage position at the end of the opening / closing body in the width direction to a reinforcing position at the center of the opening / closing body in the width direction so as to approach or come into contact with the opening / closing body 10 in the closed state from the downstream side (see Figures 2 to 4). In more detail, this movable center column 20 comprises a long center column main body 21 spanning almost the entire height of the opening / closing body 10, a hoist 22 provided at the upper end of this center column main body 21, and an engagement / disengagement mechanism 23 for engaging and disengaging the center column main body 21 with a fixed portion at the storage position and the opening / closing body reinforcement position. This movable center post 20 is suspended from a movable center post guide portion 24 fixed to an upper immovable portion (in the illustrated example, the opening / closing body storage portion 40) and moves between the storage position and the opening / closing body reinforcement position.

[0028] The center pillar body 21 is a long columnar member that extends over the entire vertical length of the opening / closing body 10 in the closed state. The center pillar body 21 has a rectangular cross section that is continuous in the vertical direction, and a plate-shaped elastic watertight member 21a that extends in the vertical direction is provided on one side of the cross section.

[0029] The center pillar body 21 is suspended by a hoist 22 so as to rotate about a vertical suspension shaft 21b. This center pillar body 21 moves between a storage position at the end of the opening / closing body in the width direction and a reinforcing position for the opening / closing body at the center of the opening / closing body in the width direction, and in the storage position, the elastic watertight member 21a faces outward in the width direction of the opening / closing body (see Figures 2 and 3). Moreover, the center pillar body 21 is rotated approximately 90 degrees at the opening / closing body reinforcing position, so that the elastic watertight member 21a faces close to or contacts the downstream side surface of the opening / closing body 10 (see FIG. 4).

[0030] The hoist 22 is configured as a roller that freely rotates around an axis in the thickness direction of the opening / closing body, and rolls in the width direction of the opening / closing body along the movable center pillar guide portion 24.

[0031] The engaging / disengaging mechanism 23 is configured to cause the rods 23b to extend and retract from the upper and lower ends of the center pillar body 21 by rotating a handle-shaped operating part 23a exposed to the outside of the center pillar body 21. A mechanism called a French drop or the like can be applied to this engaging / disengaging mechanism 23. The rod 23b engages with and disengages from receiving holes or the like (not shown) provided in the upper and lower immovable portions at each of the storage position at the end of the opening / closing body in the width direction and the opening / closing body reinforcement position at the center of the opening / closing body in the width direction.

[0032] The movable center post guide portion 24 is a horizontally elongated member that follows the movement path of the movable center post 20, and is fixed to a stationary portion above the top opening 2 (for example, the opening / closing body storage portion 40, etc.). The movable center pillar guide portion 24 illustrated in Figures 5 to 7 and the like is configured by integrating members having a U-shape in vertical cross section facing each other at a distance, and the hoist 22 is supported and rolled by its inner concave portion.

[0033] The movable center pillar storage section 32 is configured so that the movable center pillar storage opening 32a is substantially concave in cross section facing inward in the width direction of the opening / closing body (see FIG. 9), and is provided so as to extend elongatedly in the vertical direction. The movable center post storage opening 32a is a vertically long rectangular opening through which the movable center post 20 can pass in the width direction of the opening / closing body. The movable center post storage opening 32a, together with the guide opening 31a, is provided substantially flush with the inner wall material 1e.

[0034] The opening / closing body storage section 40 is located above the top opening 2 and pays out the opening / closing body 10 for a closing operation, and rewinds the opening / closing body 10 in a closed state for an opening operation. As shown in Figure 5, this opening / closing body storage section 40 supports a base 40a fixed to a fixed portion, a sprocket 41 around which the panel connecting member 13 is hung, a drive mechanism 42 that rotates this sprocket 41 in both directions, a storage rail 43 that suspends the support shaft portion 12a of the panel 12 and guides it in the forward / backward direction, and a guide member 44 that guides the guide shaft portion 12b of the panel 12 horizontally.

[0035] In this opening / closing body storage section 40, a sprocket 41 is rotated in one direction by a drive mechanism 42, thereby sequentially sending out a plurality of panels 11, 12 downward and causing them to pass through the top opening 2. The panels 11, 12 are unfurled so as to pass downward through the top opening 2 and are stacked on the lower frame member 3, thus closing off the main body passage 1a.

[0036] In addition, the opening / closing body storage section 40 opens the panels 11, 12, which are in a closed state, by rotating the sprocket 41 in the reverse direction using the drive mechanism 42, and stores them above the main body ceiling section 1b and downstream (in the illustrated example, on the indoor side). To this opening / closing body storage section 40, for example, the basic structure of Patent Document 1 can be applied.

[0037] <About the top opening and closing parts> The top opening / closing member 50 is configured in an approximately plate-like shape that covers the top opening 2 from below, and rotates about a rotation axis 50a (e.g., a hinge) that runs along the width direction of the opening / closing body to open and close between a closed position (see Figures 5 and 8) in which the top opening 2 is approximately closed, and an open position (see Figures 6 and 7) in which the top opening 2 is open. In the closed position, the top opening / closing member 50 covers the movable center pillar guide portion 24 from below, and in the open position, it allows the opening / closing body 10 to pass through in the vertical direction and the movable center pillar 20 to move in the width direction of the opening / closing body.

[0038] The top opening / closing member 50 is made up of a plurality of panels 51, 52, 53 (three in the illustrated example) that are arranged side by side in the width direction of the opening / closing body and that can rotate independently. The number of panels is set according to the width of the opening opened and closed by the opening / closing body 10, and may be a number other than that shown in the drawings (for example, one, two, or four or more).

[0039] Each of the panels 51, 52, 53 is formed in a generally rectangular plate shape in a plan view and rotates about a rotation shaft 50a that extends in the width direction of the opening / closing body on the upstream side as a fulcrum. A hook bar hook portion 50c that is recessed in a plan view is provided on the rotation end side of each of the panels 51, 52, and 53.

[0040] The hanging rod hooking portion 50c is a portion for hooking a hanging rod (not shown) having a hook-shaped engaging portion at the tip. That is, when opening the top opening / closing member 50, an operator hooks the hanging rod to the hanging rod hooking portion 50c of each panel and pulls it downward to open it. When closing the top opening / closing member 50, the operator puts the hanging rod near the hanging rod hooking portion 50c and pushes up the rotating end side of each panel.

[0041] Further, each of the panels 51, 52, and 53 is provided with one or more dampers 50d (see FIG. 8) to provide resistance to the opening operation of the panel. The number of the dampers 50d is appropriately set according to the weight and size of each panel.

[0042] The damper 50d is a well-known hydraulic damper that applies fluid resistance by oil to a piston that moves back and forth within a cylinder. According to the example shown in FIG. 8, this damper 50d has a base end side of a cylinder supported on a stationary portion with the tip rod side facing diagonally downward. With this configuration, more oil is stored in the cylinder ahead of the piston, so the amount of oil passing through the valve on the piston can be increased, and this provides a relatively large fluid resistance compared to when the damper 50d is installed substantially horizontally. Therefore, the cushioning function of the damper 50d works effectively, and the panels 51, 52, and 53 descend and open more slowly.

[0043] Further, between each of the panels 51, 52, 53 and the immovable part (lintel member 2a) facing it in the closed state, one or more attachment / detachment devices 50e for attaching and detaching each panel to and from the immovable part are provided (see FIG. 8). The attachment / detachment tool 50e attaches and detaches each panel by the magnetic force of a magnet, and may be called a magnet catcher or the like. The number of attachments 50e for each panel is set appropriately depending on the weight of each panel, etc. According to the illustrated example, the number of attachments 50e for panel 51 having an engagement / detachment device 51a described later is reduced compared to other panels 52 and 53, improving opening and closing operability.

[0044] The panel 51 located at the end-most side in the width direction of the opening / closing body is provided with an engagement / disengagement device 51a that engages the panel 51 with a fixed part (in the illustrated example, the lintel member 2a) to prevent it from being opened, and that releases this engaged state.

[0045] This engaging / disengaging device 51a includes a release button 51a1 that is pressed from below, a hook piece 51a2 that releases the hooked state with the immovable part when the release button 51a1 is pressed, and a lever 51a3 that protrudes downward in conjunction with the release of the hook piece 51a2 (see FIG. 10). For example, a lock device called a distribution board lock or the like can be applied to this engaging / disengaging device 51a. According to this engaging / disengaging device 51a, when the panel 51 in the closed state is opened, pressing the release button 51a1 releases the engaged state of the engaging piece 51a2 and causes the lever 51a3 to protrude downward, thereby enabling the panel 51 to be opened. When the panel 51 is in an open state and is to be closed and hooked to a fixed portion, by closing the panel 51 and pushing back the downwardly protruding lever 51a3, the release button 51a1 is hooked to the fixed portion and the panel 51 is maintained in the closed state.

[0046] In addition, the engagement / disengagement device 51a may be configured to engage and detach the panel 51 to and from the immovable portion by external operation.Other examples include a configuration in which the panel 51 is engaged and detached to and from the immovable portion by operating a handle, a configuration in which the panel 51 is engaged and detached to and from the immovable portion by rotating operation using a hook rod, and a configuration in which the panel 51 is engaged and detached to and from the immovable portion by pulling and pushing operations using a hook rod.

[0047] Furthermore, a sensor 50f is provided at a fixed position on the upper side of the panel 51, for detecting when the panel 51 is fully closed (see FIG. 8). The sensing unit 50f in the illustrated example is a limit switch that directly senses the closing panel 51 by an actuator. As another example of the sensing section 50f, it is possible to use a mode that senses when a magnet has attracted the panel 51, or a proximity sensor that senses the proximity of the panel 51, or the like.

[0048] The above-mentioned plurality of panels 51, 52, 53 are configured to open in sequence in conjunction with one another starting from one side in the width direction of the opening / closing body (see FIG. 10). In more detail, of the two panels 51, 52 (or 52, 53) adjacent in the width direction of the opening / closing body, one of the panels 51 (or 52) is provided with an engagement portion 50b that protrudes toward the other panel 52 (or 53) and covers the upper side. Therefore, when the one panel 51 (or 52) is rotated downward to open, the engaging portion 50b engages with the other panel 52 (or 53), and the other panel 52 (or 53) also rotates downward to open.

[0049] In this way, according to the above configuration, when the panel 51 on one side is opened, the adjacent panel 52 is opened in a following manner, and the further adjacent panel 53 is also opened. Moreover, when closing these panels 51, 52, 53, they can be closed in the reverse order to that described above.

[0050] Moreover, the engagement portion 50b is provided so as to cover the gap s1 between the two adjacent panels 51, 52 (or 52, 53) from above. More specifically, the engaging portion 50b is formed in a shape (inverted L-shaped cross section according to FIG. 10) that protrudes upward from one of the two adjacent panels 51, 52 (or 52, 53) and faces the upper side of the other panel across the gap s1. When the top opening / closing member 50 is in a fully closed state, the engaging portion 50b covers the gap s1 between the adjacent panels over substantially the entire length in the thickness direction of the opening / closing body. According to these configurations, it is possible to prevent the inside from being seen from below through the gap s1 between two adjacent panels, and thus it is possible to improve the appearance of the multiple panels 51, 52, 53.

[0051] <About the side opening and closing parts> The side opening / closing member 60 is formed in a substantially plate shape that covers the guide opening 31a and the movable center pillar storage opening 32a in the vertical direction (see Figs. 5 to 7 and 9, etc.). This side opening / closing member 60 rotates about a vertical rotation axis 60a (e.g., a hinge, etc.) as a fulcrum between a closed position (see Figures 2 and 9) that covers the guide rail 31 and the movable center column storage section 32, and an open position (see Figures 3 and 4) that exposes the guide rail.

[0052] The rotating shaft 60a is composed of a hinge or the like that rotatably connects one piece to the other piece, and connects the one piece to the lateral functional part 30 and the other piece to a fixed part on the side (the movable center column storage part 32 according to Figure 9).

[0053] A gap s2 is provided on the rotation end side of the side opening / closing member 60 so that fingers inserted from the outside can be grasped by the side opening / closing member 60 (see FIG. 9). In the illustrated example, this gap s2 is a gap between the rotation end side of the side opening / closing member 60 and the side functional portion 30 in the opening / closing body width direction.

[0054] An attachment / detachment tool 33 for attaching and detaching the side opening / closing member 60 to and from the side functional part 30 is provided on the inner side of the gap s2. The attachment / detachment device 33 may be a magnet catcher that attracts the side opening / closing member 60 by the magnetic force of a magnet, similar to the attachment / detachment device 50e, or may be other fastening / detachment devices.

[0055] According to the above configuration, a user can insert his / her fingers into the gap s2, hook the side opening / closing member 60, and pull the side opening / closing member 60 in the opening direction to separate it from the attachment / detachment tool 33, thereby opening it. In this open state, the opening / closing body 10 that performs the opening / closing operation can be inserted into the guide opening 31a of the guide rail 31, and the movement path of the movable center post 20 is secured. To close the side opening / closing member 60 in the open state, the side opening / closing member 60 is rotated in the opposite direction and attached to the attachment / detachment device 33.

[0056] Further, at the rotation end side of the side opening / closing member 60, an engagement / disengagement mechanism 61 is provided which causes a rod 61a to extend and retract upward and downward by operating an operation portion 61b exposed on the surface of the side opening / closing member 60. As with the above-mentioned engaging and disengaging mechanism 23, a mechanism such as a French drop can be applied to this engaging and disengaging mechanism 61.

[0057] When the side opening / closing member 60 is in the fully closed state (see Figures 2 and 9), the engagement / disengagement mechanism 61, when the operating part 61b is operated, causes the upper rod 61a to protrude upward and fit into a receiving hole (not shown) provided in the upper immovable part (for example, the upstream lintel member 2a or the ceiling component member, etc.), and further causes the lower rod 61a to protrude downward and fit into a receiving hole (not shown) provided in the lower immovable part (for example, the bottom frame or floor surface, etc.), thereby engaging the side opening / closing member 60 so that it cannot be opened.

[0058] When the side opening / closing member 60 is in the fully closed state (see Figure 3), the engagement / disengagement mechanism 61, when the operating part 61b is operated, causes the upper rod 61a to protrude upward and fit into a receiving hole (not shown) provided in the upper immovable part (for example, the downstream lintel member 2a or the ceiling component member, etc.), and further causes the lower rod 61a to protrude downward and fit into a receiving hole (not shown) provided in the lower immovable part (for example, the bottom frame or floor surface, etc.), thereby engaging the side opening / closing member 60 so that it does not close.

[0059] Furthermore, sensors 62, 63 are provided above the side opening / closing member 60 when it is in the fully closed position and above the side opening / closing member 60 when it is in the fully open position, respectively (see Figs. 2 to 4 and 9). One of the sensing parts 62 is fixed to a stationary portion above the engaging / disengaging mechanism 61 when the side opening / closing member 60 is in the fully closed position. The other sensing portion 63 is fixed to a stationary portion above the engaging / disengaging mechanism 61 when the side opening / closing member 60 is in the fully open position. These sensing units 62, 63 are constituted by, for example, a limit switch or a proximity switch, and sense the rod 61a protruding upward from the side opening / closing member 60, and transmit the sensing signal to a control unit (not shown).

[0060] <Control features> Next, the control features of the opening and closing device A having the above configuration will be described. The opening / closing device A enables the closing operation of the opening / closing body 10 on the condition that the top opening / closing member 50 is open and the side opening / closing member 60 is open. More specifically, a control section (not shown) of the switching device A is configured with, for example, a relay circuit, a sequencer, a microcomputer, etc., and executes the flowchart shown in FIG.

[0061] First, in step S1, it is determined whether the top opening / closing member 50 is fully closed based on the detection signal of the detection unit 50f (see FIG. 8). If it is fully closed, the process jumps to step S5, and if not, the process proceeds to step S2.

[0062] In step S2, it is determined whether the side opening / closing member 60 is fully closed based on a detection signal from the detection unit 62 (see Figs. 2 to 4). If it is fully closed, the process jumps to step S5, and if not, the process proceeds to step S3.

[0063] In step S3, it is determined whether the side opening / closing member 60 is fully open based on the detection signal from the detection unit 63 (see Figs. 2 to 4). If it is fully open, the process proceeds to step S4; if not, the process jumps to step S5.

[0064] In step S4, the opening / closing body 10 is made closable. That is, when the opening / closing body 10 is in the fully open state and a closing command is received from an operation signal of an operation switch (not shown) or an external signal, the drive mechanism 42 is operated in the closing direction to close the multiple panels 11, 12 downward.

[0065] Furthermore, in step S5, even if the closing command is received when the opening / closing body 10 is in the fully open state, the drive mechanism 42 is maintained in a stopped state so that the opening / closing body 10 does not perform a closing operation.

[0066] <Action and effect> According to the opening and closing device A configured as described above, when the opening and closing body 10 is in the fully open state, the top opening 2 can be covered and blocked by the top opening and closing member 50. This makes it possible to prevent the inside of the ceiling from being seen through a gap between the opening and closing body 10 in the fully open state and the top opening 2, and to prevent wind and rain from entering the ceiling through the gap. Furthermore, by eliminating unevenness on the ceiling surface caused by the top opening 2 using the top opening / closing member 50, the visual difference between the top opening / closing member 50 and adjacent building materials (ceiling materials, etc.) is reduced, and boundaries, etc. are made less noticeable, improving the aesthetic appearance of the ceiling surface.

[0067] Furthermore, when the opening / closing body 10 is in a fully open state and the movable center pillar 20 is stored in the movable center pillar storage section 32, the guide opening 31a and the movable center pillar storage opening 32a can be covered and blocked by the lateral opening / closing member 60. This makes it possible to prevent pedestrians or objects from interfering with the guide opening 31a and the movable center pillar storage opening 32a, and to prevent wind and rain from entering the interior through the guide opening 31a and the movable center pillar storage opening 32a, etc. Furthermore, by eliminating the unevenness of the side wall surface caused by the guide opening 31a and the movable center column storage opening 32a using the side opening / closing member 60, the visual difference between the side opening / closing member 60 and adjacent building materials (wall materials, etc.) is reduced, and the boundaries, etc. are made less noticeable, improving the aesthetic appearance of the side wall surface.

[0068] Furthermore, when either the top opening / closing member 50 or the side opening / closing member 60 is closed, the opening / closing body 10 is controlled so as not to perform a closing operation, thereby preventing the opening / closing body 10 from interfering with the top opening / closing member 50 or the side opening / closing member 60.

[0069] Second Embodiment The opening / closing device B shown in Figure 12 is configured so that only the movable center column storage section 32, which is a side functional part located on one side in the left-right direction (in the illustrated example, the right side), is covered in an openable and closable manner by a side opening / closing member 60'. That is, the guide rail 31 and the guide opening 31a that guide the opening / closing body 10 in the up and down direction are exposed without being covered by the side opening / closing members or the like. Additionally, the top opening 2 through which the opening / closing body 10 is extended is also exposed without being covered by top opening / closing members or the like. In addition, the movable center post 20 is singular and is stored in the movable center post storage section 32 on one side in the left-right direction (the right side in the illustrated example), so there is no movable center post storage section or the like on the other side. In the opening and closing device B shown in FIG. 12, components that function in substantially the same manner as the opening and closing device A are denoted by the same reference numerals as those in the opening and closing device A, and duplicated detailed description will be omitted.

[0070] According to the opening / closing device B shown in FIG. 12, the opening and closing members 60' on the side walls can reduce openings and irregularities, improving the aesthetic appearance of the side walls. In addition, the interference of passing objects and the intrusion of wind and rain can be prevented.

[0071] In addition, in this opening / closing device B, it is also possible to cover the guide rail 31 with a side opening / closing member 60', or to cover the guide rail 31 in an openable and closable manner with a side opening / closing member (not shown) separate from the side opening / closing member 60'.

[0072] Furthermore, in the opening and closing device B, similarly to the opening and closing device A, it is also possible to provide a top opening and closing member 50 that opens and closes the top opening 2.

[0073] <Other Modifications> According to the above embodiment of the opening / closing device A, the movable center column guide portion 24 is covered by the top opening / closing member 50. As another example, however, it is also possible to have only the opening through which the opening / closing body 10 is extended covered in an openable / closable manner by the top opening / closing member 50, and to leave the movable center column guide portion 24 uncovered.

[0074] According to the above embodiment, the side opening / closing member 60 is configured from a single plate-like member, but as another example, the side opening / closing member 60 can be configured from a plurality of plate-like members. In this case, for example, among the plurality of plate-like members constituting the side opening / closing member 60, some of them may close the guide opening 31a, and the other parts may close the movable center pillar storage opening 32a.

[0075] In the above embodiment, an example is given in which both the guide rail 31 and the movable center column storage section 32 are covered by the side opening / closing member 60 (see Figure 9), and an example is given in which only the movable center column storage section 32 is covered by the side opening / closing member 60' (see Figure 12). However, as another example, it is also possible to cover only the guide rail 31 by the side opening / closing member.

[0076] In the above embodiment, a side opening / closing member 60 (or 60') is provided, but as another example, it is also possible to have a configuration in which only the top opening 2 is covered by the top opening / closing member 50 without providing a side opening / closing member 60 (or 60').

[0077] According to the above embodiment, as a particularly preferred example, the open state of the side opening / closing member 60 is determined by two sensing units 62, 63, but as another example, it is also possible to determine the open state of the side opening / closing member 60 by only one of the sensing units.

[0078] According to the above embodiment, the opening / closing device AB is configured as a water-stopping shutter device, which is a mode that particularly effectively exerts the effects of the present invention. However, the present invention can also be applied to opening / closing devices (including shutter devices, overhead doors, etc.) that do not have a water-stopping function.

[0079] According to the above embodiment, the opening / closing body 10 is configured by a plurality of panels, but other examples of this opening / closing body can be configured using a plurality of slats, pipes, sheets, panels, etc. as appropriate.

[0080] According to the above embodiment, the adjacent panels 52, 53 are sequentially linked to the opening rotation of the panel 51 on one side. However, as other examples, it is also possible to have the adjacent panels 51, 53 on both sides or one side be linked to the opening movement of the panel 52 from the center, or to have only a portion of a plurality of panels be linked to be openable while the other panels are openable without being linked to one another.

[0081] 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.
