Description

[Technical field]

[0001] The present invention relates to a switchgear support structure for supporting a switchgear on a skeleton, and a method for manufacturing the switchgear support structure. [Background technology]

[0002] In broadcasting studios and other facilities, it is desirable to reduce as much as possible the vibrations and sounds that may intrude from outside the studio. Therefore, in typical studios, a floating floor is installed between the stationary floor and the floating floor, with cushioning material (such as glass wool) between the floating floor and the stationary floor, and walls and ceilings are then installed on top of the floating floor. This type of floating floor structure is effective in reducing the intrusion of vibrations from outside the studio, such as foot traffic vibrations, through the floor into the studio. Furthermore, in order to partition the studio so that it can be opened and closed, an opening and closing device is useful, as described in Patent Document 1, for example, in which a number of panels are pulled out from a storage section and stacked on the floor to close the studio.

[0003] [Patent Document 1] JP 2010-37849 A Summary of the Invention [Problem to be solved by the invention]

[0004] In order to partition the studio so that it can be opened and closed using the opening and closing device, the opening and closing device can be installed either on a fixed floor or on a floating floor. In the former embodiment, the panel abuts against the fixed floor to be fully closed, so there is a risk that vibrations from the fixed floor will be transmitted to the fully closed panel, generating vibration noise. In contrast, in the latter embodiment, the panel is abutted against a floating floor that is separated from the fixed floor and fully closed, thereby preventing vibrations from the fixed floor from being transmitted to the panel and generating vibration noise. However, even in the latter embodiment, if the storage section that unfolds the panels is supported on an immovable part near the upper floor, foot vibrations on the floor of the upper floor, etc., may be transmitted to the storage section via the immovable part, potentially causing vibration noise from the storage section. In particular, since the total weight of the storage section, including the panels, differs between the fully closed state where the multiple panels are extended to close the opening and the fully open state where the multiple panels are stored and the opening is open, the natural frequency of the entire storage section, including the panels, also differs between the fully closed state and the fully open state. Therefore, even if measures against vibration and noise are taken in the fully closed state, these vibration and noise measures may not function effectively in the fully open state, which has a different natural frequency. [Means for solving the problem]

[0005] In view of the above problems, one aspect of the present invention has the following configuration. An opening / closing device support structure in which an opening / closing device that closes an opening by an opening / closing body that is extended from a storage section and opens the opening by returning the opening / closing body toward the storage section is supported on a surrounding structure, wherein the storage section is supported on a fixed portion of the structure via a first vibration-damping member having elasticity. Effect of the Invention

[0006] Since the present invention is configured as described above, it is possible to effectively suppress the generation of vibrations and noise in the opening and closing device due to vibrations transmitted from the outside. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] <First embodiment> Next, a first embodiment of the present invention will be described in detail with reference to the drawings. The opening / closing device support structure A of the present invention is configured to support an opening / closing device 2, which closes an opening x by an opening / closing body 50 that is extended from a storage section 90 and opens the opening x by returning the opening / closing body 50 to the storage section 90 side, on a surrounding body 1.

[0009] The structure 1 is, for example, a building that constitutes a broadcasting station's studio 1a, and according to the example shown in Figure 1, it has a fixed floor 10 that is fixed in place and a floating floor 20 that is supported so as to be able to move slightly relative to the fixed floor 10 by placing a cushioning material (such as glass wool, not shown) between the fixed floor 10.

[0010] 1, the fixed floor 10 is formed in a stepped shape with a recess on the left side, and the floating floor 20 is supported in this recess via a cushioning material (not shown). The floating floor 20 has its upper surface exposed to the space above, and the fixed floor 10 has an upper surface adjacent to the floating floor 20 exposed to the space above.

[0011] A fixed-side three-sided frame 11 is fixed on the fixed floor 10 at a position adjacent to the floating floor 20. This fixed-side three-sided frame 11 is integrally formed of left and right vertical frames 11a spaced apart in the width direction of the opening / closing body, and an upper frame 11b connecting the upper ends of these vertical frames 11a. In FIG. 1, reference numeral 12 denotes a top wall portion connected to the upper end side of the fixed-side three-sided frame 11, and is fixed to a wall, beam, or the like on the fixed floor 10 side of the framework 1.

[0012] A floating-side frame 22 is provided on the floating floor 20 so that a lower guide rail 70 (described later) is placed between the fixed-side frame 11 and the floating-side frame 22. The floating-side frame 22 is integrally formed of left and right vertical frames 22a spaced apart in the width direction of the opening / closing body, and an upper frame 22b connecting the upper ends of the vertical frames 22a. 1, reference numeral 23 denotes a top wall portion connected to the upper end side of the floating-side three-sided frame 22. This top wall portion 23 is composed of a ceiling material, a wall material, etc., and is fixed to a wall, beam, etc. on the floating floor 20 side of the framework 1. The space between the ceiling wall portion 23 and the floating floor 20 is used as a broadcasting studio 1a.

[0013] A space is provided above the top walls 12 and 23 to accommodate a storage section 90, which will be described later. A beam-shaped steel material (not shown) is provided in the space to support the storage section 90. An upper floor section 30 is provided above the space.

[0014] The opening and closing device 2 comprises an opening and closing body 50 which performs a closing operation to separate a space and abuts against the floating floor 20 (the surface facing the closing direction), an upper guide rail 60 and a lower guide rail 70 which guide the opening and closing body in the vertical direction on both sides in the width direction, a lintel section 80 provided on the lower end side of the upper guide rail 60, and a storage section 90 which stores the opening and closing body 50 on the upper side when opened.

[0015] The opening / closing body 50 includes a plurality of panels 51, 52 aligned vertically in the closed state, and a flexible, long connecting member 53 (a metal chain in the illustrated example) connecting the plurality of panels 51, 52 together. This opening / closing body 50 operates to close by stacking multiple panels 51, 52 one after another on the floating floor 20 as the connecting member 53 is extended from the storage section 90. In addition, the opening / closing body 50 opens the multiple panels 51, 52 when the linking member 53 is returned to the storage section 90.

[0016] Each of the panels 51, 52 is a metal member having a rectangular plate shape when viewed from the front and is long in the width direction of the opening / closing body. According to an example shown in Fig. 2, the vertical cross-sectional shape of each of the panels 51, 52 is a generally rectangular frame shape that is long in the up-down direction and has a hollow interior. A support shaft portion 54 supported by a connecting member 53 is provided at the widthwise end portion of each of the panels 51, 52 (see FIG. 8).

[0017] The support shaft portion 54 is inserted through the connecting member 53, and rotatably supports a roller 55 at its tip end (see FIG. 9). The roller 55 rolls on a rail 91d in the storage portion 90. 9 denotes a roller-shaped anti-sway shaft that protrudes from the widthwise end on the lower end side of each of the panels 51, 52. This anti-sway shaft 56 is guided and regulated by a guide section (not shown) in the storage section 90, thereby preventing each panel from shaking in the thickness direction.

[0018] In the drawing, the panel designated by the reference numeral 51 is the panel located at the bottommost position when the door is fully closed. If necessary, an obstacle sensor for detecting an obstacle below may be provided at the bottom end of the panel 51. Moreover, the panel indicated by the reference numeral 52 is a panel that is stacked on the bottom panel 51.

[0019] As shown in FIG. 7, the upper end of each of the panels 51, 52 is formed in a generally stepped shape in vertical section with one side in the thickness direction of the opening / closing body recessed downward and the other side protruding upward.

[0020] The lower end of each panel 52 is formed in a stepped shape in vertical cross section so as to fit into the upper ends of the panels 51, 52.

[0021] Between the vertically adjacent panels 51, 52 (or 52, 52), a plurality of types of rubber cushioning materials 54a, 54b, 54c, 54d, 55a, 55b, and 55d are provided.

[0022] The cushioning materials 54a, 55a are continuous over the entire width of the panels 51, 52, respectively, and are sandwiched between the portions where the lower panels 51, 52 and the upper panel 52 overlap in the thickness direction of the opening / closing body, thereby elastically contracting in the thickness direction of the opening / closing body (see Figure 7(b)). That is, the buffer materials 54a, 55a prevent the formation of gaps through which sound passes in the portions where the lower panels 51, 52 and the upper panel 52 overlap in the thickness direction of the opening / closing body.

[0023] The cushioning materials 54b, 55b are provided so as to be sandwiched in the vertical direction between the vertically adjacent panels 51, 52 (or 52, 52) and elastically contract. In other words, the buffer materials 54b and 55b prevent gaps through which sound can pass from being formed in the portions where the lower panels 51 and 52 and the upper panel 52 overlap in the vertical direction. In the illustrated example, one of the cushioning materials 54b is fixed to the lower panels 51, 52, and the other cushioning material 55b is fixed to the upper panel 52 so as to be spaced apart from the cushioning material 54b in the thickness direction of the opening / closing body. The cushioning materials 54a, 54b, 55a, and 55b are cushioning materials with a relatively low rubber hardness, and also serve as airtight members, contributing to ensuring airtightness.

[0024] In addition, the cushioning material 54c is set to have a rubber hardness greater than those of the above-mentioned cushioning materials 54a, 55a, 54b, and 55b, and is located between the cushioning materials 54b and 55b in the thickness direction of the opening / closing body, and maintains the distance between the lower panels 51 and 52 and the upper panel 52 at a predetermined designed dimension. That is, the lower panels 51, 52 and the upper panel 52 elastically contract the cushioning materials 54b, 55b and sandwich a cushioning material 54c having a harder hardness than the cushioning materials 54b, 55b from above and below, thereby determining the vertical distance between them.

[0025] The cushioning material 54d is provided at the upper ends of the lower panels 51, 52, at one end side in the thickness direction of the opening / closing body (the left end side in FIG. 7). Similarly, the cushioning material 55d is provided at the lower end of the upper panel 52, on the other end side in the thickness direction of the opening / closing body (the right end side in FIG. 7). These cushioning materials 54d, 55d are provided separately on one end side and the other end side of the opening / closing body 50 in the width direction of the opening / closing body. Each of the cushioning materials 54d, 55d is pressed against an elastic airtight member 62a1 that is continuous in the vertical direction within the lower guide rail 70 (see FIG. 9).

[0026] The cushioning materials 54d and 55d are configured to have greater elasticity than the cushioning material 54c. That is, the cushioning materials 54d and 55d in the illustrated example are formed by stacking and integrating rubber materials 54d2 and 55d2 having a lower rubber hardness than the rubber material 54d1 and 55d1 on the panel side, the rubber material having the same rubber hardness as the cushioning material 54c. According to this configuration, the distance between the upper panel 52 and the lower panel 51 (or 52) can be determined only by the buffer material 54c, without being affected by the buffer materials 54d and 55d. According to one example of the present embodiment, the cushioning material 54c and the rubber materials 54d1 and 55d1 are made of the same rubber material.

[0027] The upper guide rails 60 are provided above the fixed-side frame 11 and the floating-side frame 22, at one end and the other end of the opening / closing body 50 in the width direction. Each upper guide rail 60 is formed with a concave cross section surrounding an end side in the width direction of the opening / closing body 50, and is continuous in an elongated shape in the vertical direction. More specifically, each upper guide rail 60 includes a guide portion 62 that guides the end portion in the width direction of the opening / closing body 50 in the up-down direction (see FIG. 9).

[0028] The guide portion 62 is integrally formed of an inner member 62a surrounding the width direction end of the opening / closing body 50 in a concave cross section, and an outer member 62b surrounding the inner member 62a in a concave cross section.

[0029] The inner member 62a is provided with elastic airtight members 62a1 in a vertically elongated shape at a position facing the front surface of the opening / closing body 50 and at a position facing the rear surface of the opening / closing body 50, respectively.

[0030] The elastic airtight member 62a1 is made of an elastic material such as rubber, or an elastically flexible fibrous member, and prevents sound leakage due to a gap that occurs between the front or back surface of the opening / closing body 50 and the guide portion 62. The elastic airtight member 62a1 is sometimes called mohair.

[0031] The upper guide rail 60 configured as described above has the guide section 62 fixed to a member of the framework 1 on the floating floor 20 side (e.g., a wall, a beam, the lower guide rail 70, etc.) with a vertical gap s1 (see FIG. 2) secured between the upper guide rail 60 and the storage section 90. In other words, the upper guide rail 60, together with the floating floor 20, is supported relative to the fixed floor 10 so as to be slightly movable. The gap s1 is appropriately set so that the storage section 90 does not come into contact with the upper guide rail 60 when the storage section 90 moves slightly up and down as the first vibration isolating member 111 elastically contracts.

[0032] In addition, as shown in Figure 9, the lower guide rail 70 has a double structure including a fixed portion 61 that is fixed to the main body 1 side in the vertical direction, and a guide portion 62 that is detachably attached to the fixed portion 61 and guides the widthwise end portion of the opening / closing body 50 in the vertical direction.

[0033] The fixing portion 61 is formed with a generally concave cross section into which the guide portion 62 can be inserted from one side in the width direction of the opening / closing body, and has a fastening piece 61a on the inside for fastening the guide portion 62. The fastening piece 61a is formed in a flat plate shape that protrudes inward in the thickness direction of the opening / closing body.

[0034] Moreover, the guide portion 62 of the lower guide rail 70 is a member having substantially the same configuration as the guide portion 62 of the upper guide rail 60. According to Fig. 9, the guide portion 62 of the lower guide rail 70 is indicated by the same reference numeral as the guide portion 62 of the upper guide rail 60. The outer member 62b of the guide portion 62 is provided with flanges 62b1 protruding on both sides in the projection direction (see FIG. 9(b)). The flanges 62b1 are overlapped with the fastening piece 61a. The fastening piece 61a and the flanges 62b1 are detachably connected by a fastener 62c (e.g., a screw, a bolt, or the like) that penetrates them.

[0035] The lower guide rail 70 is provided so as to continue downward from the upper guide rail 60, and the fixing portion 61 is fixed to a member of the framework 1 on the floating floor 20 side (for example, a wall, a beam, etc.).

[0036] In the illustrated example, of the upper guide rail 60 and the lower guide rail 70, only the lower guide rail 70 has the above-mentioned double structure, but as another example, it is also possible for both the upper guide rail 60 and the lower guide rail 70 to have the above-mentioned double structure, or for both the upper and lower guide rails to have the same structure as the upper guide rail 60. In this way, when both the upper and lower sides are made to have the same structure, the upper and lower guide rails do not need to be separated, but may be made into a continuous, integrated structure.

[0037] The lintel portion 80 is located between the upper frame 11b of the fixed-side three-sided frame 11 and the upper frame 22b of the floating-side three-sided frame 22, and functions as an outlet for sending the opening / closing body 50 downward when performing the closing operation. This lintel section 80 is composed of a fixed-side lintel member 81 located on the fixed-side jamb 11 side and a floating-side lintel member 82 located on the floating-side jamb 22 side.

[0038] The fixed lintel member 81 is a long member that continues in the width direction of the opening / closing body 50, and is supported on a stationary portion F of the frame 1 via a second vibration isolating device 120 described later.

[0039] Here, the immovable part F is a part that is immovable relative to the floating floor 20 which is movable slightly, and this immovable part F includes the fixed floor 10, as well as walls, ceilings, beams, etc. that are integral with the fixed floor 10. The immovable portion F supporting the fixed-side lintel member 81 may be, for example, a beam-shaped steel material or the like that is supported immovably on the upper side of the fixed-side lintel member 81.

[0040] The floating-side lintel member 82 faces the fixed-side lintel member 81 with the opening-closing body 50 therebetween (see FIG. 1), and is an elongated member that continues in the width direction of the opening-closing body 50. This floating-side lintel member 82 is fixed to a member of the frame 1 on the floating floor 20 side (for example, a wall, a beam, the upper guide rail 60, the lower guide rail 70, etc.).

[0041] The storage section 90 moves the opening / closing body 50, which is made up of the panels 51 and 52, to one side in the forward direction (the right side in FIG. 1) and then moves it downward to perform a closing operation. The storage section 90 also moves the opening / closing body 50, which is performing an opening operation, to the other side in the forward direction (the left side in FIG. 1) on its upper side to store it.

[0042] According to an example shown in FIG. 1, when the opening x is open, some of the multiple panels 51, 52 constituting the opening / closing body 50 are stored in a space below the storage section 90 and above the opening x in a vertical line, and the other panels are stored in the storage section 90.

[0043] The storage section 90 is integrally configured to include a storage main body section 91 for storing the opening / closing body 50 when opened, and a weight adjustment member 92 fixed to the storage main body section 91.

[0044] The storage main body 91 has a base 91a, a sprocket 91b around which the connecting member 53 is wound, a drive mechanism 91c (e.g., an electric motor, a drive sprocket, a chain, etc.) that rotates the sprocket 91b in both directions, and rails 91d that transport multiple panels 51, 52 in the forward direction.

[0045] The base body 91a is made of a rigid material such as a plurality of steel members or metal panels and has, for example, a frame or box shape. The upper end side of the connecting member 53, which is hung on the sprocket 91b, has a hanging portion 53a which is connected to the base 91a so as to be movable in the forward direction but not in the vertical direction.

[0046] The weight adjustment member 92 is made of a metal material having rigidity and is formed into a rectangular pipe shape long in the width direction of the opening / closing body. According to the illustrated example, the weight adjustment member 92 is provided on the opening / closing body storage side (left side in Figs. 1 and 2) and the opening / closing body extension side (right side in Figs. 1 and 2) in the projection direction of the base 91a, and is fixed to the upper end of the base 91a by suitable fixing means (for example, welding, bolting, etc.). The weight adjustment member 92 adjusts the total weight of the storage section 90 so that the natural frequency of the storage section 90 becomes equal to or less than a first specified value, which will be described later.

[0047] In detail, the weight adjustment member 92 adjusts the total weight of the storage section 90 so that when the opening-closing body 50 is fully closed, the natural vibration frequency of the storage section 90 is below a first specified value, and when the opening-closing body 50 is fully open, the natural vibration frequency of the storage section 90 is below a second specified value that is smaller than the first specified value.

[0048] That is, when fully closed, the weight of the opening / closing body 50 is supported by the floating floor 20, so the total weight of the storage section 90 becomes relatively light. Therefore, the natural frequency of the storage section 90 becomes relatively high. In contrast, when fully open, the weight of the opening / closing body 50 is added, so the total weight of the storage section 90 becomes heavier than when it is closed. Therefore, the natural frequency of the storage section 90 becomes lower than when it is fully closed. In this embodiment, the weight of the entire storage section 90 including the weight adjustment members 92 is set by adjusting the length, size, material, quantity, etc. of the weight adjustment members 92 so that the natural frequency of the entire storage section 90 is below the first specified value when fully closed and below the second specified value when fully open.

[0049] In the illustrated example, a weight adjustment member 92 is connected to the first vibration-damping device 110 on the opening / closing body storage side (left side in Figures 1 and 2), and a weight adjustment member 92 is fixed to the storage main body 91 on the opening / closing body extension side (right side in Figures 1 and 2). However, the installation positions, quantities, etc. of these weight adjustment members 92 can be appropriately adjusted and set to a configuration other than that shown in the illustrated example.

[0050] The first and second specified values ​​are set to values ​​smaller than 20 Hz because a typical audible frequency is 20 Hz or higher. In a preferred example of the present embodiment, the first specified value is set to 14 Hz, and the second specified value is set to 10 Hz.

[0051] The natural frequency can be estimated from the height H (see FIG. 5) of the first vibration isolating member 111 and the second vibration isolating member 121 when compressed. For example, when the height dimension H of the first vibration isolating member 111 is reduced, it can be estimated that the weight of the storage section 90 is increased and the natural frequency is reduced. In this embodiment, the relationship between the height dimension H and the natural frequency is expressed by a formula, and the natural frequency is derived from the height dimension H.

[0052] The storage section 90 having the above-mentioned configuration is supported at a plurality of points by immovable parts F of the frame 1 (for example, beams, pillars, walls, etc.) on the frame 1 side via first vibration isolation devices 110. And, below the storage section 90, the fixed lintel member 81 is supported by a stationary part F on the frame 1 side via a second vibration isolating device 120 having substantially the same configuration as the first vibration isolating device 110.

[0053] The first vibration-damping device 110 comprises a first vibration-damping member 111 made of an elastic material, a receiving member 112 that receives the first vibration-damping member 111 on the lower side and is fixed to a fixed portion F, and a connecting member 113 that is placed on the upper end of the first vibration-damping member 111 and connected to the storage section 90 (see Figures 2 and 3).

[0054] The first vibration isolating member 111 is a cylindrical member made of a rubber material, with its central axis oriented in the vertical direction. This first vibration-isolating member 111 is connected to a receiving member 112 and a connecting member 113 by bolts, nuts, etc. This first vibration-isolating member 111 is sandwiched between the receiving member 112 and the connecting member 113 to support the weight of the storage section 90 and elastically contract.

[0055] The receiving member 112 is a rigid metal member. The receiving member 112 in the illustrated example is formed in an L-angle shape, one side of which receives the first vibration-isolating member 111 and the other side of which is fixed to the immovable portion F.

[0056] The connecting member 113 is a rigid metal member. The connecting member 113 in the illustrated example is formed in an L-angle shape, with one piece placed on and fixed to the upper end of the first vibration-isolating member 111, and the other piece fixed to the base 91a or the weight adjustment member 92 in the storage section 90.

[0057] The first vibration isolating devices 110 having the above-mentioned configuration support the storage section 90 near one end and the other end in the width direction of the opening / closing body, and are provided in plurality so as to support the storage section 90 also on the central side. According to the example shown in FIG. 3, four of the first vibration isolation devices 110 are provided on one end side in the width direction of the storage section 90, four on the other end side, and two on the center side.

[0058] Further, a plurality of first vibration isolation devices 110 are provided so as to support the storage section 90 on one side and the other side in the projection direction. Furthermore, the number of first vibration-damping devices 110 supporting the storage section 90 on the opening / closing body extension side (right side in Figure 2) is greater than the number of first vibration-damping devices 110 supporting the same storage section 90 on the opposite side (left side in Figure 2).

[0059] That is, the number of first vibration isolators 110 supporting the storage section 90 on the opening / closing body payout side (the right side in FIG. 2) is six, spaced apart vertically and in the opening / closing body width direction (see FIG. 3). In contrast, the number of first vibration isolation devices 110 supporting the storage section 90 on the opening / closing body storage side (left side in FIG. 2) is four, lined up in the opening / closing body width direction above the weight adjustment member 92 (see FIG. 3).

[0060] The second vibration-damping device 120, similar to the first vibration-damping device 110, comprises a second vibration-damping member 121 made of an elastic material, a receiving member 122 that receives the second vibration-damping member 121 on the lower side and is fixed to a fixed part F, and a connecting member 123 that is placed on the upper end of the second vibration-damping member 121 and connected to the fixed side lintel member 81 (see Figure 5).

[0061] In addition, storage section slippage prevention devices 130a, 130b are provided between the storage section 90 and the immovable portion F to prevent the storage section 90 from moving in the horizontal direction, and a lintel slippage prevention device 140 is provided between the fixed side lintel member 81 and the immovable portion F to prevent the fixed side lintel member 81 from moving in the horizontal direction.

[0062] One of the storage section anti-slip devices 130a is configured to elastically contract an anti-slip member 131 made of an elastic material (e.g., rubber) by abutting against a fixed portion F of the main body 1 when the storage section 90 moves in the width direction (left and right direction in Figure 3) due to an earthquake or the like. As shown in FIG. 3, this storage section slippage prevention device 130a is provided on both sides of immovable parts F (e.g., beam-shaped steel material, etc.) spaced apart vertically at the center of the width direction of the storage section 90 on the opening / closing body extension side. Each storage section slippage prevention device 130a is composed of a slippage prevention member 131 that faces the immovable part F with a predetermined gap s2 in the width direction, and a support member 132 that supports the slippage prevention member 131 and connects it to the storage section 90. The gap s2 is set to about several millimeters.

[0063] The other storage section anti-slip device 130b is configured to elastically contract an anti-slip member 131 made of an elastic material (e.g., rubber) by abutting against a fixed portion F of the main body 1 when the storage section 90 moves in the expected direction (left and right direction in Figure 2) due to an earthquake or the like. As shown in Figs. 2 and 3, the storage section slippage prevention devices 130b are provided on the left and right sides in the width direction of the storage section 90 on the opening / closing body extension side. Each storage section anti-slip device 130b consists of an anti-slip member 131 facing in one of the projecting directions (the right direction in Figure 2), an anti-slip member 131 facing in the opposite direction (the left direction in Figure 2), and a support member 132 fixed to the storage section 90 so as to support these two anti-slip members 131.

[0064] One of the anti-slip members 131 is supported by a support member 132 so as to face a plate-like member f1 integral with the immovable portion F with a gap s2 therebetween. The collapse prevention member 131 facing in the opposite direction is supported by a support member 132 so as to face, with a gap s2 therebetween, the inner surface of a fixing member f2, which has a generally U-shaped cross section and is fixed to a plate-like member f1. The support member 132 is a member that protrudes from the storage section 90 and is bent into approximately an L shape, and supports the two anti-slip members 131 described above at the bent portion (see Figures 2 and 3), and has its base end fixed to the base body 91a.

[0065] In addition, the lintel slippage prevention device 140 is configured so that when the fixed lintel member 81 moves in the expected direction (left and right direction in Figure 2) due to an earthquake or the like, the slippage prevention member 141 made of an elastic material (e.g., rubber, etc.) abuts against the immovable part F of the main body 1 and elastically contracts. This lintel slippage prevention device 140 is composed of two slippage prevention members 141 facing one and the other in the projection direction, and a support member 142 that supports these slippage prevention members 141 at their center (see FIG. 5).

[0066] The two opposing anti-slip members 141 face the fixed member f3 with a gap s2 therebetween. The fixed member f3 is formed in an inverted concave shape surrounding the two opposing anti-slip members 141, as shown in FIG. 5(b), and is fixed to the immovable portion F via the receiving member 122. Each of the anti-slip members 141 is disposed adjacent to the inner surface of the fixing member f3 with a gap s2 therebetween.

[0067] 3 and 6, reference numeral 151 denotes a rigid support member that is used only when the storage section 90 is installed on the frame 1. As shown in FIG. More specifically, the rigid support members 151 are detachably provided at a plurality of locations, such as both sides in the width direction of the storage main body portion 91 and both sides in the width direction of the weight adjustment members 92 (see FIG. 3). Each rigid support member 151 is screwed downwardly into a bracket 152 integral with the storage section 90, and its lower end abuts against a fixed portion F to support the storage section 90 immovably.

[0068] <Action and effect> The operation and effect of the opening and closing device support structure A having the above configuration during manufacture and during use after manufacture will be described in detail below.

[0069] First, in the operation of installing the storage unit 90 on the main body 1, the storage unit 90 is placed on the immovable portion F of the main body 1 via a plurality of rigid support members 151 (see FIG. 6(a)). In this state, the lower end of each rigid support member 151 abuts against the immovable portion F, and the storage section 90 is placed immovably without shaking or sinking. As a result, operations such as attaching some of the parts that make up the storage section 90 to the storage main body 91 and the weight adjustment member 92 (for example, attaching the upper end of the connecting member 53 (chain) to the base 91a, installing the drive shaft, installing the opening / closing motor, hanging the panel, etc.) and ensuring a specified gap s2 between the anti-slip member 131 and the immovable part F can be performed efficiently in a stable state.

[0070] Thereafter, all of the rigid support members 151 are loosened and removed to allow the storage unit 90 to descend under its own weight, and the storage unit 90 is elastically supported by the multiple first vibration-isolating members 111. Fig. 6(b) shows a state in which the storage unit 90 has sunk down by dimension y as the first vibration-isolating members 111 have contracted under its own weight.

[0071] In this support state, for example, the upper floor portion 30 or the fixed floor 10 may be subjected to a force such as walking. When vibration occurs, the vibration is absorbed by the plurality of first vibration-isolating members 111 and second vibration-isolating members 121. Therefore, the vibration on the immovable part F side can be prevented from being transmitted to the storage section 90 or the fixed side lintel member 81 and generating vibration noise.

[0072] In particular, according to the above embodiment, the number of first vibration-damping members 111 on the opening / closing body extension side, which tends to be heavy when fully open, is greater than the number of first vibration-damping members 111 on the opposite side. Therefore, the amount of compression of the first vibration-damping members 111 can be appropriately ensured both when fully open and when fully closed, and thus the transmission of vibration from the immovable part F to the storage section 90 can be effectively reduced.

[0073] Even if vibrations that cannot be absorbed by the first vibration-damping member 111 and the second vibration-damping member 121, or vibrations caused by an earthquake, are transmitted to the storage section 90 or the fixed side lintel member 81, the natural vibration frequencies of the storage section 90 and the fixed side lintel member 81 are set lower than the audible frequency, so vibration noise is unlikely to be generated. In particular, the natural vibration frequencies of the storage section 90 when fully closed and fully open are set to be equal to or lower than the first specified value and the second specified value, respectively, as described above, so that the generation of noise caused by the vibration of the storage section 90 can be effectively prevented regardless of the open / close position of the opening / closing body 50.

[0074] Furthermore, according to the above embodiment, when the opening / closing body 50 is fully closed, it is abutted against the floating floor 20 rather than the fixed floor 10, thereby preventing vibrations from the fixed floor 10 from being transmitted to the opening / closing body 50, causing the opening / closing body 50 to generate vibration noise. That is, the floating floor 20 is separated from the fixed floor 10 via a cushioning material (such as glass wool), and its natural frequency is set below the audible frequency. This makes it possible to prevent vibrations on the fixed floor 10 side from being transmitted to the components on the floating floor 20 side (the floating-side three-sided frame 22, the floating-side lintel component 82, the top wall portion 23, the opening / closing body 50 when fully closed, etc.) and generating vibration noise.

[0075] Furthermore, according to the above embodiment, for example, when the storage section 90 or the fixed lintel member 81 attempts to move significantly in the horizontal direction due to large vibrations such as an earthquake, the slippage prevention member 131 abuts against the immovable portion F. This prevents the first vibration-isolating member 111 and the second vibration-isolating member 121 from being bent or deformed due to the movement, which would cause the storage section 90 and the fixed side lintel member 81 to be unable to maintain their proper positions.

[0076] Furthermore, according to the above embodiment, cushioning materials 54b, 55b, 54a, and 55a are provided between adjacent panels 51 (or 52) and 52, which are sandwiched vertically between these panels and elastically contract. This not only reduces the impact noise generated when these panels come into contact, but also prevents gaps that could cause sound leakage between the upper and lower panels when the panel is fully closed.

[0077] Furthermore, according to the above embodiment, at least the lower guide rail 70 has a double structure consisting of the fixed portion 61 and the guide portion 62 (see FIG. 9), so that the guide portion 62 can be easily attached to and detached from the fixed portion 61. Furthermore, it is possible to easily perform operations such as fitting the opening / closing body 50 into the lower guide rail 70 when assembling the opening / closing device 2, and removing the opening / closing body 50 from the lower guide rail 70 for maintenance, etc.

[0078] <Second embodiment> According to the opening / closing device support structure A shown in FIG. 1, when the opening x is open, some of the multiple panels 51, 52 are arranged in a vertical line in the space below the storage section 90 and above the opening x, and the other panels 52 are stored within the storage section 90. However, as another example, it is possible to increase the number of panels arranged in the vertical line. For example, in the opening / closing device support structure B shown in Figure 10, of the multiple panels 51, 52, only the topmost panel 52 is pulled further back (to the left as shown) than sprocket 91b within the storage section 90, the second-highest panel 52 is stored in front of the sprocket 91b within the storage section 90 (to the right as shown), and the other panels 51, 52 are stored in a vertical line within the upper guide rail 60' on the lower side of the storage section 90.

[0079] In the opening / closing device support structure B, the portion of the connecting member 53 that is closer to the hanging side than the uppermost panel 52 sags toward the lower side of the storage section 90 so as to fit along the multiple panels 52 that are lined up in the vertical direction. The hanging portion 53a of the connecting member 53 is shifted toward the opening / closing body extension side of the base body 91a (the right side in FIG. 10).

[0080] In addition, the opening / closing device 3 in this opening / closing device support structure B is obtained by replacing the upper guide rail 60 of the above-mentioned opening / closing device 2 with an upper guide rail 60' and adding a linking member case 91e.

[0081] The upper guide rail 60' is set to a length capable of accommodating the panels 51, 52 other than the uppermost two panels 52, 52. The connecting member case 91e is formed in an elongated shape extending in the vertical direction so as to cover the downwardly loosened connecting member 53. If a space for loosening the connecting member 53 can be secured below the storage section 90, the connecting member case 91e can be omitted.

[0082] Therefore, according to the opening and closing device support structure B shown in Figure 10, the space above the three-sided frames 11, 22 can be effectively utilized to store multiple panels 51, 52 in a vertically linear manner, and these panels 51, 52 can be opened and closed quickly and with relatively little vibration.

[0083] <Third embodiment> In the opening and closing device 3 of the opening and closing device support structure B shown in Figure 10, the uppermost two panels 52 are stored within the storage section 90, and the other panels 51, 52 are stored below the storage section, but in the opening and closing device 3 of the opening and closing device support structure C shown in Figure 11, all of the panels 51, 52 are stored below the storage section 90. In other words, in the opening / closing device 3 configured as described above, when the opening x is opened, some or all of the multiple panels 51, 52 can be stored in a vertical line in the space below the storage section 90 and above the opening x, thereby making effective use of the space above the frames 11, 22 and enabling the opening / closing body 50 to be opened and closed quickly and with little vibration.

[0084] <Other Modifications> According to the above embodiment, as a particularly preferred aspect, the first vibration-damping member 111 and the second vibration-damping member 121 are formed from a rubber material, but as an example other than the example shown in the figures, these vibration-damping members can also be made from an elastic material other than rubber, a spring, etc.

[0085] Furthermore, according to the above embodiment, the opening / closing body 50 is constructed from a plurality of panels as an embodiment with particularly good soundproofing performance, but other examples of this opening / closing body include an opening / closing body made of a plurality of slats connected in the vertical direction, an opening / closing body made of a flexible sheet, an opening / closing body made of a pipe-shaped member, or an opening / closing body made by appropriately combining slats, a flexible sheet, a pipe-shaped member, etc.

[0086] In addition, the opening / closing device 2 shown in Figures 1 and 2 is configured to store multiple panels 51, 52 separately, but the storage method for the opening / closing body can also be such that the various opening / closing bodies described above are rolled up for storage, slid for storage, folded for storage, etc.
