Description

[Technical Field]

[0001] The present invention relates to a panel member fastener for attaching a panel member to a scaffold. [Background technology]

[0002] Scaffolding is used for high-altitude work at construction sites and the like, and panels (hereinafter referred to as panel members) such as soundproofing panels are attached to the scaffolding to block noise and prevent the spread of dust. Conventionally, panel members have been fastened to wooden members attached to the scaffolding with screws, which has led to the problem of low work efficiency when assembling and dismantling the scaffolding.

[0003] Various methods have been proposed to solve such problems. For example, Patent Document 1 discloses a scaffolding panel connecting member that includes a connecting member main body having an upper groove portion that opens upward and into which a lower end portion of an upper scaffolding panel member of the plurality of scaffolding panel members arranged vertically is inserted, and a lower groove portion that opens downward and into which an upper end portion of a lower scaffolding panel member of the plurality of scaffolding panel members is inserted, and a fixing member that fixes the scaffolding panel member inserted into the lower groove portion to the connecting member main body, wherein the connecting member main body detachably supports the scaffolding panel member inserted into the upper groove portion without fixing it to the upper groove portion.

[0004] In the scaffolding panel connecting member of Patent Document 1, the lower end of the scaffolding panel member located above is inserted into the upper groove, and the upper end of the scaffolding panel member located below is inserted into the lower groove. At this time, the scaffolding panel member inserted into the lower groove is fixed by a fixing member. On the other hand, the scaffolding panel member inserted into the upper groove is not fixed and can be freely attached and detached. Therefore, the scaffolding panel member can be connected and disassembled efficiently. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2023-09152 Summary of the Invention [Problem to be solved by the invention]

[0006] In the technology of Patent Document 1, because scaffolding panel members need to be inserted into upper and lower gutter sections, the widths of the upper and lower gutter sections must be larger than the thickness of the scaffolding panel members. Furthermore, while the upper end of the scaffolding panel member is inserted into the lower gutter section and fixed by a fixing member, the lower end of the scaffolding panel member is not fixed. Therefore, the scaffolding panel member may have low resistance to horizontal forces. In the embodiment of Patent Document 1, the horizontal resistance is thought to be increased by separately fixing the scaffolding panel member to the scaffolding frame member. In this case, a separate process is required for attaching and detaching the scaffolding panel member to the scaffolding panel connecting member, which prevents the full benefit of the invention of Patent Document 1.

[0007] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a panel member fixing device that allows panel members to be easily attached and detached to scaffolding and can reliably fix the panel members. [Means for solving the problem]

[0008] In order to solve the above problem, the panel member fixing device of the present invention for attaching a panel member to scaffolding is a panel member fixing device for attaching a panel member to scaffolding, and comprises: a rear wall having a fixed portion on its outer side that is fixed directly or indirectly to the scaffolding; and an inner body provided on the inner side of the rear wall, wherein the inner body comprises a front wall whose upper end is located lower than the upper end of the rear wall and which is arranged opposite the rear wall at a position spaced from the inner side of the rear wall; and a connecting member provided from the upper end of the front wall to the rear wall so as to be perpendicular to the rear wall, and wherein the fixing member is displaceable between a retracted position in which the entire body does not protrude from the upper end of the inner body when viewed from the front, and a protruding position in which a part of the fixing member protrudes from the upper end of the inner body, and wherein the connecting member supports the lower end of the panel member, and when in the protruding position, the fixing member clamps and fixes the panel member between its protruding portion and the rear wall.

[0009] This panel member fastener is used to fasten the vicinity of the lower end of a panel member. In this configuration, with the fastening member displaced to the retracted position, the panel member is pushed into contact with the rear wall, and the lower end of the panel member is placed on the connecting member. This positions the outer side surface and the lower end of the panel member. In this state, by displacing the fastening member to the protruding position, the panel member is clamped and fixed between the rear wall and the fastening member. With the fastening member in the retracted position, it does not get in the way when removing or attaching the panel member, making it easier to remove or attach the panel member. Furthermore, by displacing the fastening member to the protruding position, the panel member is clamped and fixed between the fastening member and the rear wall, thereby ensuring reliable fixation of the panel member.

[0010] In addition, the panel member fixing device for attaching a panel member to scaffolding according to the present invention comprises a rear wall having a fixed portion on its outer side that is fixed directly or indirectly to the scaffolding, and an inner body provided on the inner side of the rear wall, the inner body comprising a front wall whose lower end is located higher than the lower end of the rear wall and which is arranged opposite the rear wall at a position spaced from the inner side of the rear wall, and a connecting member provided across the front wall and the rear wall, and a fixing member that is displaceable between a retracted position in which the entire body does not protrude from the lower end of the inner body when viewed from the front, and a protruding position in which a part of the fixing member protrudes from the lower end of the inner body, and in the protruding position, the fixing member clamps and fixes the panel member between its protruding portion and the rear wall.

[0011] This panel member fastener is used to fasten the vicinity of the upper end of a panel member. In this configuration, with the fastening member displaced to the retracted position, the panel member is pushed into contact with the rear wall, thereby positioning the outer side surface of the panel member. In this state, by displacing the fastening member to the protruding position, the panel member is clamped and fixed between the rear wall and the fastening member. With the fastening member in the retracted position, it does not get in the way when removing or attaching the panel member, making it easier to remove or attach the panel member. Furthermore, by displacing the fastening member to the protruding position, the panel member is clamped and fixed between the fastening member and the rear wall, thereby ensuring reliable fixation of the panel member.

[0012] In one preferred embodiment of the panel member fastener according to the present invention, the fastening member is displaceable between the retracted position and the extended position by swinging about an axis parallel to the normal to the rear wall.

[0013] In this configuration, the retracted position and the extended position can be shifted by a simple operation of swinging the fixing member.

[0014] In one preferred embodiment of the panel member fastener according to the present invention, the rear wall and the front wall have insertion holes formed at opposing positions, the fixing member is located between the rear wall and the front wall, the fixing member has a screw hole with a female thread formed therein, and a bolt has a shaft portion formed with a male thread that fits the female thread of the screw hole, and the bolt is inserted into the insertion hole. R At the same time, it is screwed into the screw hole.

[0015] In this configuration, the bolt is only inserted through the rear wall and the front wall, so the rotation of the bolt does not affect the rear wall or the front wall. On the other hand, because the bolt is threadedly engaged with the fixing member, the rotation of the bolt is transmitted to the fixing member as a rotational force. In this case, if the rotation of the fixing member is restricted, the rotational force of the bolt is transmitted to the fixing member as a translational force. In other words, if the bolt is turned while the rotation of the fixing member is restricted, the fixing member moves away from or toward the rear wall. This allows the distance between the fixing member and the rear wall to be changed. Therefore, this can be applied to panel members of different thicknesses. [Brief explanation of the drawings]

[0017] An embodiment of a panel component fastener according to the present invention will be described below with reference to the drawings. FIG. 1 is a partial front view showing a state in which a panel component P has been attached to a scaffolding B using a panel component fastener A according to the present invention. Normally, M×N panel components P are attached to the scaffolding B, but only a portion of them is shown here. Furthermore, this drawing shows only the vertical single pipes vp arranged in the vertical direction among the components that make up the scaffolding B. In this embodiment, the panel component P is a soundproof panel, but the panel component P is not limited to this and other plate-like components such as plywood and baseboards can also be used.

[0018] Fig. 2(a) is a front view of the panel member fastener A, (b) is a rear view, and (c) is a left side view. However, bolts 8 and nuts 9, which will be described later, are omitted from Figs. 2(a) and 2(b). Note that the height direction, width direction, and thickness direction in the present invention and this embodiment refer to the up-down direction in Fig. 2(a), the left-right direction in Fig. 2(a), and the left-right direction in Fig. 2(c), respectively. Also, the right side of Fig. 2(c) is referred to as the inner side, and the left side is referred to as the outer side.

[0019] As shown in the figure, panel member fixing device A comprises a first plate-shaped member 1 (an example of the rear wall in the present invention) having a horizontally long plate shape, and a second plate-shaped member 2 (an example of the front wall in the present invention) arranged opposite and spaced apart from the first plate-shaped member 1. The height direction length of the second plate-shaped member 2 is shorter than that of the first plate-shaped member 1, and the width direction length is the same as that of the first plate-shaped member 1. The width direction lengths of the first plate-shaped member 1 and the second plate-shaped member 2 can be changed as appropriate depending on the width direction length of the panel member P to be used.

[0020] A plurality of insertion holes 1a and 2a are formed in opposing positions of the first plate-shaped member 1 and the second plate-shaped member 2, respectively. Specifically, four insertion holes 1a, 2a are formed above the center and four insertion holes 1a, 2a are formed below the center along the width axis. As will be described later, the shanks of bolts 8 are inserted into these insertion holes 1a, 2a. Note that no female threads are formed on the inner peripheral surfaces of the insertion holes 1a, 2a.

[0021] Pockets 1b (an example of a fixed portion in the present invention) are formed near both widthwise ends of the outer side surface of the first plate-like member 1. The pockets 1b are hollow rectangular parallelepipeds that are open at the top and bottom. As will be described later, the pockets 1b are used when attaching the panel member fixing device A to the scaffolding B.

[0022] FIG. 3 is a perspective view of the panel member fastener A with the second plate-shaped member 2 removed. Note that the bolts 8 and nuts 9 are omitted in this figure as well. As shown in the figure, a plate-shaped upper partition member 3 (an example of a connecting member in the present invention) is provided above the center between the first plate-shaped member 1 and the second plate-shaped member 2, and a plate-shaped lower partition member 4 (an example of a connecting member in the present invention) is provided below the center. Specifically, as shown in FIG. 2(c), the upper partition member 3 extends horizontally from the upper end of the second plate-shaped member 2 toward the first plate-shaped member 1, and the lower partition member 4 extends horizontally from the lower end of the second plate-shaped member 2 toward the first plate-shaped member 1. In this embodiment, the second plate-shaped member 2, the upper partition member 3, and the lower partition member 4 constitute the inner body in the present invention. The thickness dimensions of the upper partition member 3 and the lower partition member 4 can be appropriately changed depending on the thickness of the panel member P used, and in this embodiment, they are set to be larger than the thickness of the panel member P.

[0023] As shown in Figures 2(c) and 3, eight rectangular plate-shaped fixing members 5 are provided between the first plate-shaped member 1 and the second plate-shaped member 2. In this embodiment, four fixing members 5 are arranged above the center and four fixing members 5 are arranged below. Hereinafter, when distinguishing between these, the fixing members 5 arranged above will be referred to as upper fixing members 6, and the fixing members 5 arranged below will be referred to as lower fixing members 7. The number of fixing members 5 can be changed as appropriate.

[0024] In Figure 3(a), the fixing member 5 is arranged so that its long axis is parallel to the width axis of the first plate-shaped member 1. In this state, in a front view, the upper fixing member 6 does not protrude above the upper ends of the second plate-shaped member 2 and the upper partition member 3, i.e., the upper end of the inner body, and the lower fixing member 7 does not protrude below the lower ends of the second plate-shaped member 2 and the lower partition member 4, i.e., the lower end of the inner body. Therefore, the position of the fixing member 5 in Figure 3(a) corresponds to the retracted position in this invention.

[0025] On the other hand, in Figure 3(b), a portion of the upper fixing member 6 protrudes upward from the upper ends of the second plate-shaped member 2 and the upper partition member 3, i.e., the upper end of the inner body, and a portion of the lower fixing member 7 protrudes downward from the lower ends of the second plate-shaped member 2 and the lower partition member 4, i.e., the lower end of the inner body. Therefore, the position of the fixing member 5 in Figure 3(b) corresponds to the protruding position in the present invention. As will be described in detail later, in the panel member fixing device A according to this embodiment, the fixing member 5 can be displaced between the retracted position and the protruding position by turning the bolt 8.

[0026] A screw hole 6a is formed in a position offset in the width direction from the center of the upper fixing member 6 when the upper fixing member 6 is in the retracted position. Similarly, a screw hole 7a is formed in a position offset in the width direction from the center of the lower fixing member 7 when the lower fixing member 7 is in the retracted position. Specifically, the screw hole 5a (a collective term for the screw holes 6a and 7a) of the fixing member 5 located to the left of the center in the width direction is offset to the left, and the screw hole 5a of the fixing member 5 located to the right is offset to the right. When viewed from the front, the fixing member 5 is positioned so that the insertion hole 1a of the first plate-like member 1 and the insertion hole 2a of the second plate-like member 2 overlap with the screw hole 5a. As described below, a bolt 8 is inserted through the insertion hole 1a, the screw hole 5a, and the insertion hole 2a. A female thread is formed on the inner surface of the screw hole 5a to be threaded onto a male thread formed on the shank of the bolt 8. Note that the bolts 8 in this embodiment include both right-handed and left-handed threads. Specifically, the screw holes 5a are as follows. The bolts 8 used for the upper fixing member 6 located in the left half are right-handed threads, the bolts 8 used for the upper fixing member 6 located in the right half are left-handed threads, the bolts 8 used for the lower fixing member 7 located in the left half are left-handed threads, and the bolts 8 used for the lower fixing member 7 located in the right half are left-handed threads.

[0027] 2(c), with the first plate-shaped member 1, fixing member 5, and second plate-shaped member 2 arranged in this manner, the shank of a bolt 8 is inserted through the insertion hole 1a of the first plate-shaped member 11, the screw hole 5a of the fixing member 5, and the insertion hole 2a of the second plate-shaped member 2 (the screw hole 5a of the fixing member 5 and the bolt 8 are screwed together), and the bolt is fastened with a nut 9. At this time, the nut 9 is tightened so that the head of the bolt 8 and the nut 9 are in close contact with each other to such an extent that the bolt 8 can rotate relative to the first plate-shaped member 1 and the second plate-shaped member 2. The nut 9 is then fixed to the bolt 8 so that the bolt 8 and the nut 9 rotate together.

[0028] As described above, because no female threads are formed on the inner peripheral surfaces of the insertion holes 1a, 2a, when the bolt 8 or nut 9 is turned, the bolt 8 rotates freely relative to the first plate-like member 1 and the second plate-like member 2. On the other hand, because the bolt 8 is threadedly engaged with the threaded hole 5a of the fixing member 5, when the bolt 8 or nut 9 is turned, the fixing member 5 also rotates when the fixing member 5 is in a state in which the fixing member 5 is freely rotatable, and when the rotation of the fixing member 5 is restricted, the relative positions of the fixing member 5 and the bolt 8 in the thickness direction are displaced.

[0029] As shown in FIG. 3 , in this embodiment, the upper partition member 3 and the lower partition member 4 each have four openings 3a, 4a. The width of the opening 3a is slightly longer than the longitudinal length of the upper fixing member 6, and the width of the opening 4a is slightly longer than the longitudinal length of the lower fixing member 7. The upper fixing member 6 is located directly below the opening 3a, and the lower fixing member 7 is located directly above the opening 4a. However, the upper fixing member 6 and the lower fixing member 7 located on the left side in the width direction are offset to the left relative to the openings 3a and 4a, respectively. On the other hand, the upper fixing member 6 and the lower fixing member 7 located on the right side in the width direction are offset to the right relative to the openings 3a and 4a, respectively. The fixing member 5 can be displaced to a protruding position by partially protruding from the upper or lower end of the inner body through these openings 3a and 4a.

[0030] Next, the operation of displacing the fixing member 5 between the retracted position and the extended position will be described using FIG. 3 . First, the operation of displacing the upper fixing member 6, located on the left side in the width direction, from the retracted position to the extended position will be described. The bolt 8 of the upper fixing member 6, which is in the retracted position shown in FIG. 3( a), is rotated counterclockwise. Because the insertion hole 1 a of the first plate-shaped member 1 and the insertion hole 2 a of the second plate-shaped member 2 are not female-threaded, the bolt 8 rotates freely relative to the first plate-shaped member 1 and the second plate-shaped member 2. However, the female thread of the screw hole 5 a of the fixing member 5 is threadedly engaged with the male thread of the shank of the bolt 8, and therefore the counterclockwise rotation of the upper fixing member 6 is not restricted. Therefore, the upper fixing member 6 begins to rotate counterclockwise together with the bolt 8. As this rotation occurs, a portion of the upper fixing member 6 protrudes above the upper partition member 3 through the opening 3 a. Then, as shown in FIG. 3(b), when the left long side of the upper fixing member 6 abuts against the left end of the opening 3a, counterclockwise rotation of the upper fixing member 6 is restricted. If the bolt 8 is further rotated counterclockwise in this state, because the bolt 8 is a right-handed thread, a force acts in a direction that moves the bolt 8 and the upper fixing member 6 relatively away from each other. At this time, since movement of the bolt 8 in the thickness direction is restricted, the upper fixing member 6 moves in the thickness direction. Specifically, the upper fixing member 6 moves toward the tip side of the bolt 8, i.e., toward the first plate-like member 1.

[0031] The same applies to the operation of the other fixing members 5, but for the upper fixing member 6 located on the right side in the width direction and the lower fixing member 7 located on the left side, the fixing member 5 can be displaced from the retracted position to the protruding position by turning the bolt 8 clockwise. Also, for the lower fixing member 7 located on the right side in the width direction, the lower fixing member 7 can be displaced from the retracted position to the protruding position by turning the bolt 8 counterclockwise.

[0032] Furthermore, when the fixing member 5 is to be displaced from the protruding position to the retracted position, the bolt 8 is turned in the direction opposite to the above-mentioned direction.

[0033] Next, a method for attaching a panel member P to scaffolding B using a panel member fixing tool A will be described. In this embodiment, a curing clamp 10 (a demon clamp) is fixed to the vertical single pipe vp of scaffolding B, and the panel member fixing tool A is attached to scaffolding B via the curing clamp 10. The panel member P is then attached via the panel member fixing tool A.

[0034] As shown in FIG. 4, the curing clamp 10 comprises a substantially arc-shaped first clamp member 101 and a substantially arc-shaped second clamp member 102. One end of the second clamp member 102 is fixed to one end of the first clamp member 101 by a pin 103 so as to be rotatable about an axis 103a of the pin 103. By rotating the second clamp member 102 about the axis 103a, the curing clamp 10 can be moved between an open position and a closed position. A fixing bolt 104 is connected to the free end of the first clamp member 101 (the end not provided with the pin 103) by a pin 105 so as to be rotatable about the axis 105a of the pin 105. Meanwhile, a groove 106 is formed in the free end of the second clamp member 102 (the end not provided with the pin 103) into which the tip of the fixing bolt 104 fits. A nut 107 is provided near the tip of the fixing bolt 104. Additionally, the first clamp member 101 of the curing clamp 10 is provided with a pair of L-shaped hooks 108 on its outer periphery. When clamping the vertical single pipe vp with this curing clamp 10, the vertical single pipe vp is sandwiched between the first clamp member 101 and the second clamp member 102, and the fixing bolt 104 is inserted into the groove 106 and tightened with a nut 107 to secure it in place.

[0035] As shown in Figure 5, these curing clamps 10 are fixed to the vertical pipes vp of scaffolding B. Specifically, multiple curing clamps 10 are fixed to each vertical pipe vp at a predetermined height. In the figure, two curing clamps 10 are fixed to each of the three vertical pipes vp. In the following explanation, the curing clamp 10 fixed at height position h1 will be referred to as curing clamp 10L, and the curing clamp 10 fixed at height position h2 will be referred to as curing clamp 10H.

[0036] Next, as shown in Figure 6, panel component fasteners A are attached to the curing clamps 10 attached to the vertical single pipes vp in this way. Specifically, panel component fasteners A are attached across the curing clamps 10 attached at the same height to adjacent vertical single pipes vp. Specifically, the left-side pocket 1b of the panel component fastener A on the right side in the figure is inserted from its bottom end into the hook 108 on the right side of the curing clamp 10 in the figure, and the right-side pocket 1b of the panel component fastener A on the left side in the figure is inserted from its bottom end into the hook 108 on the left side of the curing clamp 10 in the figure. In this way, the panel component fasteners A can be fixed across the adjacent vertical single pipes vp.

[0037] If the thickness direction length of the hollow portion of pocket 1b is too large compared to the diameter of hook 108, the panel member fixing device A may become unsteady, so it is preferable that the thickness direction length of the hollow portion of pocket 1b be approximately the same size as the diameter of hook 108.

[0038] Next, a method for attaching a panel component P to a panel component fastener A will be described using FIG. 7. Note that FIG. 7 shows the panel component fasteners AH and AL attached to the curing clamps 10H and 10L in FIG. 5, but does not include the vertical single pipe vp or the curing clamps 10. As shown in FIG. 5, the panel component fasteners AL and AH are separated by a distance δh in the height direction. This distance δh is set so that the distance from the top surface of the upper partition member 3 of the lower panel component fastener AL to the bottom surface of the lower partition member 4 of the upper panel component fastener AH is equal to or greater than the height length of the panel component P, and the distance from the top end of the upper fastening member 6 in the protruding position of the lower panel component fastener AL to the bottom end of the lower fastening member 7 in the protruding position of the upper panel component fastener AH is shorter than the height length of the panel component P.

[0039] First, before attaching the panel member P, the fixing members 5 of all panel member fixing devices A are displaced to the retracted position, and the fixing members 5 are brought close to the second plate-shaped member 2. At this time, the thickness direction length between the first plate-shaped member 1 and the fixing members 5 is greater than the thickness of the panel member P. In this state, as shown in FIG. 7(a), an L-shaped recess 1c is formed by the first plate-shaped member 1 and the upper partition member 3. Meanwhile, an inverted L-shaped recess 1d is formed by the first plate-shaped member 1 and the lower partition member 4.

[0040] Next, as shown in Figure 7(b), the panel member P is fitted across the recess 1c of the lower panel member fastener AL and the recess 1d of the upper panel member fastener AH. Specifically, the lower end of the panel member P is placed on the upper surface of the upper partition member 3 of the lower panel member fastener AL, and the panel member P is pressed down so that it abuts against the first plate-shaped member 1. In this embodiment, the distance δh is set so that a slight gap is formed between the upper end of the panel member P in the position shown in Figure 7(b) and the underside of the lower partition member 4 of the upper panel member fastener AH.

[0041] In this state, the panel member P is not fixed to the panel member fastener A, so it is necessary to press the panel member P toward the panel member fastener A with a hand or the like to prevent it from falling over. Then, as described above, the bolt 8 is rotated so that all of the fastening members 5 are in the protruding position (see FIG. 7(c)). At this time, the distance from the upper end of the upper fastening member 6 of the lower panel member fastener AL to the lower end of the lower fastening member 7 of the upper panel member fastener AH is shorter than the height of the panel member P, so it is possible to prevent the panel member P from falling over. However, in this state, the distance between the fastening members 5 and the first plate-shaped member 1 is greater than the thickness of the panel member P, so the panel member P is not fixed.

[0042] From this state, when the bolt 8 is further rotated, the fixing member 5 moves toward the first plate-shaped member 1 as described above, and the panel member P is clamped and fixed between the fixing member 5 and the first plate-shaped member 1, as shown in Figure 7(d). When fixing the panel member P, it is desirable to fix the upper end side of the panel member P with the lower fixing member 7 of the upper panel member fixing device AH, and then fix the lower end side of the panel member P with the upper fixing member 7 of the lower panel member fixing device AL.

[0043] On the other hand, when removing the panel member P, the bolt 8 of the panel member fastener A is rotated in the opposite direction to when it was fastened. As described above, the fastening member 5 tends to rotate with the rotation of the bolt 8 in the opposite direction, but the rotation of the fastening member 5 is restricted by hand or other means to a predetermined position. This moves the fastening member 5 toward the second plate-shaped member 2, and the distance between the fastening member 5 and the first plate-shaped member 1 becomes greater than the thickness of the panel member P. Then, all the fastening members 5 are displaced to the retracted position, and the panel member P is removed. Note that while the upper fastening member 6 of the lower panel member fastener AL may be restricted from rotating in the retracted position, it is preferable to restrict the rotation of the lower fastening member 7 of the upper panel member fastener AH in the protruding position. This prevents the panel member P from falling over.

[0044] In this way, by using the panel member fastener A according to the present invention, the panel member P can be attached and detached in the same substantially vertical position as when it was fastened. Furthermore, by simply turning the bolt 8 of the panel member fastener A, it is possible to securely fasten and release the fastening. Furthermore, because the distance between the first plate-like member 1 and the fastening member 5 is variable, panel members P of different thicknesses can be securely fastened. Furthermore, the panel member P can be used as both an interior and exterior lining.

[0045] [Another embodiment] (1) In the above-described embodiment, the fixing member 5 is provided between the first plate-shaped member 1 and the second plate-shaped member 2, but the fixing member 5 may also be provided on the inner side of the second plate-shaped member 2. In this configuration, since the fixing member 5 cannot move in the thickness direction, it is preferable to make the distance between the inner surface of the first plate-shaped member 1 and the outer surface of the fixing member 5 approximately the same as the thickness of the panel member P. In this configuration, as long as the panel member P has a specific thickness, the panel member P can be reliably fixed, similar to the panel member fixing device A in the above-described embodiment.

[0046] (2) In the above-described embodiment, the fixed member 5 can be moved between the retracted position and the extended position by rotating, but the method of movement is not limited to this. For example, the fixed member 5 may be configured to move up or down vertically to change its position. Furthermore, other configurations may be used as long as the object of the present invention is achieved.
