Description

[Technical field]

[0001] The present invention relates to a panel system and a partition device. [Background technology]

[0002] In spaces such as offices, public facilities, and commercial facilities, it is common to partition the space formed within the facility using a partition device. For example, Patent Document 1 discloses the configuration of a partition device (partition) that includes a plurality of panels and a connecting member that connects the plurality of panels to each other. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-169932 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the configuration disclosed in Patent Document 1, the angle between the panels is fixed by a connecting member. Therefore, if it is desired to change the angle between the panels, multiple types of connecting members must be prepared to match the angle, which is time-consuming and costly. The present invention aims to provide a panel system and partition device that can easily change the angle between panels without preparing multiple types of connecting members, and that can reduce the effort and cost required to change the angle between a first panel and a second panel. [Means for solving the problem]

[0005] In order to achieve the above object, a panel unit according to one embodiment of the present invention comprises a first panel and a second panel arranged side by side in a first direction, and a connecting member connecting the first panel and the second panel, the connecting member comprising a first mounting plate portion, a second mounting plate portion arranged at a distance from the first mounting plate portion, and a connecting portion between the first mounting plate portion and the second mounting plate portion that connects the first mounting plate portion and the second mounting plate portion so as to be rotatable relative to each other around a rotation axis extending in a transverse direction intersecting the first direction, the connecting member being capable of changing an attachment state of the connecting member to the first panel and the second panel between a first configuration in which the connecting portion is arranged between the first panel and the second panel, and the first mounting plate portion is supported by the first panel while the second mounting plate portion is supported by the second panel, and a second configuration in which at least one of the first mounting plate portion and the second mounting plate portion is supported across the first panel and the second panel.

[0006] In this way, the first form is realized by arranging the connecting member so that the connecting portion is disposed between the first panel and the second panel, one of the first mounting plate portions is supported by the first panel, and the other of the first mounting plate portions is supported by the second panel. In the first form, the first panel and the second panel, together with the first mounting plate portion and the second mounting plate portion, can rotate relatively around the rotation axis of the connecting portion. This makes it possible to arbitrarily adjust the angle between the first panel and the second panel without preparing multiple types of connecting members according to the angle. As a result, the effort and cost required to change the angle between the first panel and the second panel can be reduced. In the second embodiment, at least one of the first mounting plate and the second mounting plate is supported across both the first panel and the second panel. With this, in a state in which the first panel and the second panel are linearly arranged in the first direction, the relative displacement between the first panel and the second panel in a direction that increases or decreases the angle between the first panel and the second panel is restricted by at least one of the first mounting plate and the second mounting plate. As a result, the first panel and the second panel can be firmly connected in a state in which they are linearly arranged. Therefore, there is no need to use different connecting members for the first and second forms. By simply changing the mounting state of the same connecting member, it is possible to easily change the angle between the panels without having to prepare multiple types of connecting members.

[0007] In a panel unit according to one embodiment of the present invention, in the second form, with the axial direction of the pivot shaft arranged along the first direction, the connecting portion is arranged straddling the first panel and the second panel along the first direction, and one end of each of the first mounting plate portion and the second mounting plate portion is supported by the first panel in the axial direction, and the other end of each of the first mounting plate portion and the second mounting plate portion is supported by the second panel, so that both the first mounting plate portion and the second mounting plate portion are supported straddling the first panel and the second panel. According to this configuration, the first mounting plate portion and the second mounting plate portion are supported by the first panel and the second panel, respectively, while being arranged so as to straddle the first panel and the second panel. As a result, when the first panel and the second panel are arranged linearly in the first direction, the relative displacement between the first panel and the second panel in a direction that increases or decreases the angle between the first panel and the second panel is restricted by both the first mounting plate portion and the second mounting plate portion. As a result, the first panel and the second panel can be firmly connected in a linear arrangement. Therefore, there is no need to use different connecting members for the first and second forms. By simply changing the mounting state of the same connecting member, it is possible to easily change the angle between the panels without having to prepare multiple types of connecting members.

[0008] In a panel unit according to one embodiment of the present invention, in the second form, one of the first mounting plate portion and the second mounting plate portion may be supported across the first panel and the second panel, the other of the first mounting plate portion and the second mounting plate portion may be supported by one of the first panel and the second panel, and the connecting portion may be positioned overlapping one of the first panel and the second panel. According to this configuration, one of the first mounting plate portion and the second mounting plate portion is supported across the first panel and the second panel, so that when the first panel and the second panel are arranged linearly in the first direction, relative displacement between the first panel and the second panel in a direction that increases or decreases the angle between the first panel and the second panel is regulated by one of the first mounting plate portion and the second mounting plate portion. Since the first configuration and the second configuration can be switched by changing the mounting positions of the connecting members relative to the first panel and the second panel, the mounting state of the connecting members can be easily changed between the first configuration and the second configuration.

[0009] In a panel unit according to one embodiment of the present invention, the first panel and the second panel each include a pair of panel materials and a support structure sandwiched between the pair of panel materials, and the connecting member may be connected to the support structure between the pair of panel materials for each of the first panel and the second panel. According to this configuration, the connecting member is connected to the support structure between the pair of panel materials for each of the first and second panels, so that the attachment portions of the connecting member to each of the first and second panels are prevented from being exposed to the outside. Also, by connecting the connecting member to the support structure, the first and second panels are firmly connected to each other.

[0010] In a panel unit according to one embodiment of the present invention, the first panel and the second panel each have a planar portion that intersects in a thickness direction of the first panel and the second panel, and the connecting member may be connected to the first panel and the second panel while abutting against the planar portion. According to this configuration, the connecting member abuts against the planar portions of the first panel and the second panel, respectively, thereby enabling the first panel and the second panel to be firmly connected to the connecting member.

[0011] In a panel unit according to one embodiment of the present invention, a locking hole may be formed in either the connecting member or the planar portion, and a locking protrusion capable of locking into the locking hole may be formed in the other of the connecting member or the planar portion, and the locking protrusion may be configured to lock into the locking hole in a state in which the first panel and the second panel can be displaced relatively in the first direction. According to this configuration, the connecting member can be connected to each of the first panel and the second panel by engaging the locking protrusion with the locking hole. The locking protrusion allows the first panel and the second panel to be displaced relative to the locking hole in the first direction, so that the distance between the first panel and the second panel in the first direction can be changed. This makes it possible to prevent the ends of the first panel and the second panel from interfering with each other when, in the first form, the first panel and the second panel, together with the first mounting plate portion and the second mounting plate portion, are rotated relatively around the rotation axis of the connecting portion to adjust the angle between the first panel and the second panel.

[0012] The partition device according to the present invention comprises the panel system described above. In such a partition device, the first panel and the second panel are installed on an installation surface facing upward, and the first panel and the second panel are arranged side by side in a direction along the installation surface, thereby partitioning an indoor space formed above the installation surface. In such a partition device, by changing the attachment state of the connecting members to the first panel and the second panel, it is possible to provide a partition device that makes it possible to easily change the angle between the panels without preparing multiple types of connecting members. Effect of the Invention

[0013] According to one aspect of the present invention, it is possible to provide a panel system and partition device that can easily change the angle between panels without preparing multiple types of connecting members, thereby reducing the effort and cost required to change the angle between a first panel and a second panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Hereinafter, embodiments for carrying out the panel system and partition device according to the present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] (First embodiment) FIG. 1 is a perspective view showing the appearance of a panel unit 10 according to this embodiment. FIG. 2 is a cross-sectional view taken along the line II in FIG. 1. FIG. 3 is a perspective view showing the internal configuration of the panel unit 10 with one panel material 30 removed. FIG. 4 is a perspective view showing the internal configuration of the panel unit 10 from a different direction than FIG. 5 with the other panel material 30 removed. FIG. 5 is a view of the panel unit 10 with one panel material 30 removed, viewed from a second direction Dt. <Panel unit> The panel unit 10 shown in Fig. 1 is applied to a partition device 1 (see Fig. 24) which will be described in detail later. As shown in Figs. 1 to 5, the panel unit 10 includes a support structure 20 and a pair of panel materials 30.

[0017] <Support structure> As shown in Figs. 3 to 5, the support structure 20 is disposed between a pair of panel materials 30. The support structure 20 includes vertical frame members 21 and horizontal frame members 22. The vertical frame members 21 extend in the up-down direction (intersecting direction) Dv. In this embodiment, the vertical frame members 21 have, for example, a circular tube shape extending in the up-down direction Dv along the vertical direction. The support structure 20 is made of, for example, metal or resin, and has higher rigidity than the panel body 31 of the panel material 30.

[0018] The horizontal frame members 22 extend on both sides of the vertical frame members 21 in a first direction Dw intersecting with the up-down direction Dv. In other words, the vertical frame members 21 support the horizontal frame members 22 at their intermediate portions in the first direction Dw. In this embodiment, the horizontal frame members 22 are disposed at intermediate portions of the vertical frame members 21 in the up-down direction Dv. The height dimension of the horizontal frame members 22 in the up-down direction Dv is lower (smaller) than that of the vertical frame members 21. In the illustrated example, the dimension of the horizontal frame members 22 in the up-down direction Dv is set to about 1 / 3 of the overall length of the vertical frame members 21. As a result, the support structure 20 of this embodiment, which includes the vertical frame members 21 and the horizontal frame members 22, is formed in a cross shape when viewed from the up-down direction Dv and the second direction Dt intersecting with the first direction Dw (the direction intersecting with the first direction Dw as viewed from the up-down direction Dv). That is, in the support structure 20, the vertical frame members 21 protrude on both sides in the up-down direction Dv and the horizontal frame members 22 protrude on both sides in the first direction Dw with respect to the intersections of the vertical frame members 21 and the horizontal frame members 22. In this embodiment, the intermediate portion in the up-down direction Dv refers to a portion of the vertical frame members 21 excluding the portions that protrude on both sides in the up-down direction Dv with respect to the horizontal frame members 22, and is preferably, for example, a portion excluding 1 / 4 regions located on both sides in the up-down direction Dv with respect to the entire length of the vertical frame members 21. In the illustrated example, an area of ​​about 1 / 3 located in the middle of dividing the entire length of the vertical frame members 21 into thirds constitutes the intermediate portion in the up-down direction Dv.

[0019] The horizontal frame material 22 integrally has a plate portion 23 and a flange portion 24. The plate portion 23 extends along the first direction Dw with the second direction Dt as the thickness direction. The height dimension of the plate portion 23 in the up-down direction Dv is smaller (lower) than the width dimension of the plate portion 23 in the first direction Dw. The flange portions 24 are formed on the top and bottom of the plate portion 23. The flange portions 24 rise from the plate portion 23 toward the other panel material 30 in the second direction Dt. The flange portions 24 extend in the first direction Dw. In this way, the horizontal frame material 22 is formed in a U-shape when viewed from the first direction Dw.

[0020] 3 and 4, a groove-shaped portion 22d extending in the up-down direction Dv is formed in the center of the horizontal frame member 22 in the first direction Dw. An intermediate portion of the vertical frame member 21 in the up-down direction Dv is fitted into the groove-shaped portion 22d. The vertical frame member 21 and the horizontal frame member 22 are joined together at the groove-shaped portion 22d by an appropriate joining means such as bolt joining, rivet joining, or welding.

[0021] <Panel material> 2 to 5, the pair of panel materials 30 are disposed on both sides of the support structure 20 in the second direction Dt. The pair of panel materials 30 are disposed on both sides of the support structure 20 so as to sandwich the support structure 20. Each of the pair of panel materials 30 is supported by the support structure 20.

[0022] Each panel material 30 includes a plate-shaped panel body 31 and a bracket 35. The panel body 31 is formed in a rectangular shape when viewed from the second direction Dt. The panel body 31 is, for example, integrally molded from nonwoven fabric, or configured such that a core material is covered with a covering material such as woven fabric. Hereinafter, of the panel body 31 (panel material 30), the surface exposed to the outside as the panel material 30 may be referred to as the front surface, and the surface not exposed to the outside as the panel material 30 may be referred to as the back surface.

[0023] In the following description, when describing the configuration of each component of the panel material 30 that is the same among the panel materials 30, the description will be given mainly by taking one of the panel materials 30 as an example. The panel main body 31 integrally includes a facing portion 31f and a panel outer edge portion 31g. The facing portion 31f is formed to face the support structure 20 in the second direction Dt. The surface shape of the facing portion 31f is formed linearly in a vertical cross section along the up-down direction Dv, and is formed in a convex arc shape in a direction away from the support structure 20 from the outer end portion of the first direction Dw toward the center portion in a horizontal cross section along the first direction Dw. However, the surface shape of the facing portion 31f may be formed in an arc shape in a vertical cross section and a horizontal cross section, or may be formed in a flat surface perpendicular to the second direction Dt. The surface shape of the facing portion 31f may be formed in an arc shape in a direction approaching the support structure 20 in either a vertical cross section or a horizontal cross section. The back surface of the facing portion 31f is formed in a flat surface perpendicular to the second direction Dt.

[0024] The panel outer edge portion 31g is formed on the outer periphery side of the facing portion 31f. Here, in the panel material 30, the direction away from the center of the panel material 30 as viewed from the second direction Dt is the outer periphery side, and the direction approaching the center of the panel material 30 is the inner periphery side. The panel outer edge portion 31g is formed along the four sides of the panel main body 31. The panel outer edge portion 31g extends toward the other panel material 30 in the second direction Dt with respect to the facing portion 31f. The panel outer edge portion 31g extends while curving toward the other panel material 30 in the second direction Dt as it moves from the facing portion 31f toward the outer periphery side. As a result, the panel outer edge portions 31g of the pair of panel materials 30 protrude in a direction approaching each other in the second direction Dt. The panel outer edge portions 31g of the pair of panel materials 30 surround the periphery of the support structure 20 (both sides in the vertical direction Dv and the first direction Dw).

[0025] The bracket 35 is disposed on a side of the panel body 31 facing the other panel material 30 in the second direction Dt. The bracket 35 is made of, for example, resin. The bracket 35 is fixed to the panel body 31. The bracket 35 is disposed on the outer periphery of the panel material 30. In this embodiment, the bracket 35 is disposed at the four corners of the panel body 31. The brackets 35 are disposed on both sides of the vertical frame material 21 in the first direction Dw and on both sides of the horizontal frame material 22 in the up-down direction Dv. The upper bracket 35 with respect to the horizontal frame material 22 is placed on the horizontal frame material 22. The horizontal frame material 22 is sandwiched in the up-down direction Dv by the upper bracket 35 and the lower bracket 35 with respect to the horizontal frame material 22.

[0026] Each bracket 35 is formed separately in an L-shape spanning each corner 31c of the panel main body 31. In each bracket 35, a portion extending from the corner 31c in the up-down direction Dv constitutes a vertical extension portion 35a, and a portion extending from the corner 31c in the first direction Dw constitutes a horizontal extension portion 35b.

[0027] Fig. 6 is a perspective view showing a bracket 35 constituting the panel material 30. Fig. 7 is a perspective view showing a bracket 35 different from that in Fig. 6. 2, 3, 6, and 7, each bracket 35 integrally includes a fixed base 35d, an extending wall 35w, and a bracket edge 35g. The fixed base 35d constitutes the appearance of the bracket 35 as viewed from the second direction Dt, and extends in an L-shape along the rear surface of the panel main body 31 across the vertical extension portion 35a and the horizontal extension portion 35b. The fixed base 35d is fixed to the rear surface of the panel main body 31. The extending wall 35w extends from the outer peripheral edge of the fixed base 35d toward the other panel material 30 in the second direction Dt.

[0028] As shown in FIG. 2, the bracket edge 35g is formed in the extending wall 35w at a position facing the panel outer edge 31g of the panel main body 31 in the second direction Dt. The bracket edge 35g extends from the tip 35e of the extending wall 35w (the end on the other panel material 30 side in the second direction Dt) to the outer periphery side perpendicular to the second direction Dt. The brackets 35 of the pair of panel materials 30 face each other with the tip 35e of the extending wall 35w and the bracket edge 35g abutting each other. That is, the outer peripheries of the pair of panel materials 30 abut each other via the bracket 35 at a position that does not overlap with the support structure 20 when viewed from the second direction Dt (both sides in the vertical direction Dv with respect to the horizontal frame material 22).

[0029] The panel outer edge portion 31g of the panel main body 31 abuts against the bracket edge portion 35g. As a result, in the portion where the bracket 35 is provided, the bracket edge portion 35g is sandwiched between the pair of panel main bodies 31. In this embodiment, the panel outer edge portion 31g covers the bracket edge portion 35g from the outside in the second direction Dt, so that the panel outer edge portion 31g and the bracket edge portion 35g are disposed flush with each other on the outermost peripheral surface of the panel material 30. However, it is also possible that only the panel outer edge portion 31g constitutes the outermost peripheral surface of the panel material 30, and the bracket edge portion 35g is located on the inner peripheral side of the panel outer edge portion 31g.

[0030] 3 and 4, each bracket 35 is formed with a joining portion 36 or a joined portion 37. For example, bracket 35A arranged at two diagonally opposing corners 31c of the four corners of panel main body 31 constituting panel material 30 is formed with joining portion 36. Bracket 35B arranged at the remaining two diagonally opposing corners 31c of the four corners of panel main body 31 constituting panel material 30 is formed with joined portion 37.

[0031] Here, the first panel material 30A (see FIG. 3) and the second panel material 30B (see FIG. 4), which are provided as a pair of panel materials 30 facing each other with the support structure 20 in between, have the same configuration. That is, the first panel material 30A and the second panel material 30B each have brackets 35A arranged at two corners 31c facing each other in one diagonal direction, and brackets 35B arranged at the remaining two corners 31c facing each other in the other diagonal direction. The first panel material 30A and the second panel material 30B are arranged with their orientations in the second direction Dt different from each other. As a result, the brackets 35A arranged at the two corners 31c facing each other in one diagonal direction of the first panel material 30A and the brackets 35B arranged at the remaining two corners 31c facing each other in the other diagonal direction of the second panel material 30B face each other in the second direction Dt. In addition, brackets 35B arranged at two diagonally opposing corners 31c of the first panel material 30A face brackets 35A arranged at the remaining two diagonally opposing corners 31c of the second panel material 30B. In this manner, brackets 35A, 35B are provided in pairs between corresponding corners 31c of the pair of first panel material 30A and second panel material 30B.

[0032] As shown in Fig. 6, in this embodiment, the joint portion 36 is provided in the bracket 35A at a boundary portion between the vertical extension portion 35a and the horizontal extension portion 35b of the fixed base portion 35d. The joint portion 36 includes a cylindrical protrusion portion 36t. The protrusion portion 36t protrudes from the fixed base portion 35d toward the other panel material 30 in the second direction Dt. The protrusion portion 36t includes an elastic claw 36k that is elastically deformable.

[0033] As shown in Fig. 7, in this embodiment, the joinable portion 37 is provided in the bracket 35B at the boundary between the vertical extension portion 35a and the horizontal extension portion 35b of the fixed base portion 35d. The joinable portion 37 is formed in a cylindrical shape protruding from the fixed base portion 35d toward the other panel material 30 in the second direction Dt. The joinable portion 37 has a recess 37s into which the protrusion 36t can be inserted. The recess 37s has a hole 37h into which the elastic claw 36k engages when the protrusion 36t is inserted a predetermined distance into the recess 37s. The elastic claw 36k engages with the hole 37h, thereby locking the protrusion 36t and the recess 37s.

[0034] As shown in FIG. 2, a pair of panel materials 30 (first panel material 30A, second panel material 30B) are arranged such that a bracket 35A of one panel material 30 faces a bracket 35B of the other panel material 30 at each corner 31c. A joining portion 36 (convex portion 36t) of the bracket 35A of one panel material 30 fits into a joining portion 37 (concave portion 37s) of the bracket 35B of the other panel material 30. As a result, the bracket 35A of one panel material 30 and the bracket 35B of the other panel material 30 are joined at each corner 31c. In this way, the pair of panel materials 30 are joined together via the brackets 35 at the four corners.

[0035] Of the pair of panel materials 30, the bracket 35 of the first panel material 30A and the bracket 35 of the second panel material 30B are connected at positions that do not overlap with the support structure 20 when viewed from the second direction Dt. As a result, the brackets 35 provided on the outer peripheries of the pair of panel materials 30 abut against each other at positions that do not overlap with the support structure 20 when viewed from the second direction Dt. In this state, the panel outer edge portions 31g of the panel bodies 31 of the pair of panel materials 30 are spaced apart in the second direction Dt by the thickness of the bracket edge portions 35g.

[0036] Each bracket 35 is engaged with the horizontal frame member 22. Specifically, as shown in Figs. 3 and 4, a bracket engagement hole 22h and an engagement groove 22m are formed in the horizontal frame member 22. The bracket engagement hole 22h is formed at a predetermined position in the plate portion 23. The bracket engagement hole 22h is formed penetrating the plate portion 23. The engagement grooves 22m are formed in the upper and lower flange portions 24 of the plate portion 23, respectively. The engagement grooves 22m are open on the tip edges of the flange portions 24.

[0037] FIG. 8 is a cross-sectional view showing the structure of the engaging portion of the bracket 35 with respect to the horizontal frame member 22. As shown in FIG. As shown in Figs. 6 to 8, the vertical extension 35a of each bracket 35 is formed with a locking member 38 that is locked to the horizontal frame member 22. The bracket 35 arranged on the upper side with respect to the horizontal frame member 22 is provided with the locking member 38 at the lower end of the vertical extension 35a. The bracket 35 arranged on the lower side with respect to the horizontal frame member 22 is provided with the locking member 38 at the upper end of the vertical extension 35a. The locking member 38 is formed in an L-shape when viewed from the first direction Dw. Specifically, the locking member 38 integrally includes a locking base 38a that protrudes and extends from the vertical extension 35a in the up-down direction Dv, and a locking claw 38b that protrudes from the locking base 38a toward the other panel member 30 in the second direction Dt.

[0038] 8, in bracket 35P that is provided on the first panel material 30A and disposed on the upper side relative to the horizontal frame member 22, locking claw 38b is inserted into bracket locking hole 22h. This restricts movement of bracket 35P and panel main body 31 (first panel material 30A) to which bracket 35P is fixed in the up-down direction Dv and the first direction Dw.

[0039] In bracket 35Q, which is provided on the second panel material 30B and disposed on the upper side relative to the horizontal frame material 22, locking base 38a is inserted into locking groove 22m. This restricts movement of bracket 35Q and panel main body 31 (panel material 30B) to which bracket 35Q is fixed in the first direction Dw. Note that, due to the connection between connecting portion 36 and connected portion 37, movement of bracket 35Q in the up-down direction Dv is restricted relative to bracket 35P facing it in the second direction Dt. In this manner, the lower ends of brackets 35P, 35Q arranged on the upper side of horizontal frame member 22 are supported by horizontal frame member 22 via locking members 38.

[0040] In bracket 35R, which is provided on the first panel material 30A and disposed below the horizontal frame material 22, locking claw 38b is inserted into bracket locking hole 22h. This restricts movement of bracket 35R and panel main body 31 (first panel material 30A) to which bracket 35R is fixed in the up-down direction Dv and the first direction Dw.

[0041] In bracket 35S, which is provided on the second panel material 30B and disposed below the horizontal frame material 22, locking base 38a is inserted into locking groove 22m. This restricts movement of bracket 35S and panel main body 31 (second panel material 30B) to which bracket 35S is fixed in the first direction Dw. Note that, due to the connection between connecting portion 36 and connected portion 37, movement of bracket 35S in the up-down direction Dv is restricted relative to bracket 35P facing it in the second direction Dt. In this manner, the lower ends of the brackets 35R, 35S arranged on the lower side of the horizontal frame member 22 are supported by the horizontal frame member 22 via the locking members 38.

[0042] <Vertical connection structure of panel units> Fig. 9 is a perspective view showing a structure for vertically connecting the panel units 10. Fig. 10 is a perspective view showing a structure for connecting a base leg 70 to the lower side of the panel unit 10. Fig. 11 is a cross-sectional view showing an upper connecting member 28 that constitutes the upper connecting portion 26 of the panel unit 10. As shown in Fig. 9, the panel unit 10 is configured so that other panel units 10 can be connected above and below. Also, as shown in Fig. 10, the panel unit 10 is configured so that a base leg 70 can be connected to the lower side. Specifically, the support structure 20 includes a lower connecting portion 25 and an upper connecting portion 26.

[0043] As shown in Figures 9 to 11, the upper connecting part 26 is provided at the upper end part of the support structure 20. The upper connecting part 26 is provided at the upper end part 21t of the vertical frame member 21. The upper connecting part 26 is configured so that the lower connecting part 25 of one panel unit 10 arranged above the other panel unit 10 can be connected to the upper end part 21t of the vertical frame member 21 in one panel unit 10. The upper connecting part 26 includes an upper connecting member 28 and a restraining member 29.

[0044] As shown in Fig. 11, the upper connecting member 28 includes a first semi-cylinder member 28A and a second semi-cylinder member 28B. The first semi-cylinder member 28A and the second semi-cylinder member 28B are each formed in a substantially semi-cylindrical shape extending in the up-down direction Dv. The first semi-cylinder member 28A and the second semi-cylinder member 28B are each disposed along the outer circumferential surface of the vertical frame member 21. The first semi-cylinder member 28A and the second semi-cylinder member 28B are disposed to face each other in the first direction Dw with the vertical frame member 21 in between. The first semi-cylinder member 28A and the second semi-cylinder member 28B form the upper connecting member 28 into a substantially cylindrical shape extending in the up-down direction Dv as a whole.

[0045] 9 and 10, a pair of flanges 27 protruding on both sides in the second direction Dt are formed on the outer circumferential surface of the upper connecting member 28 (first semi-cylinder member 28A, second semi-cylinder member 28B). Each flange 27 extends in the up-down direction Dv. The flanges 27 include an upper flange 27A and a lower flange 27B that are spaced apart in the up-down direction Dv.

[0046] 3 and 4, through holes 21h are formed in the vertical frame material 21 in order to attach the upper connecting member 28. A plurality of through holes 21h are formed at appropriate intervals in the up-down direction Dv.

[0047] As shown in Fig. 11, the lower end of each of the upper connecting members 28 (first half-cylinder member 28A, second half-cylinder member 28B) is formed with a lower end locking claw 28t that can be locked into the through hole 21h of the vertical frame member 21. The upper end of the first half-cylinder member 28A is formed with a screw insertion hole 28h that communicates with the other through hole 21h in a state in which the lower end locking claw 28t is locked into the through hole 21h. The upper end of the second half-cylinder member 28B is formed with a boss 28b that is inserted into the other through hole 21h in a state in which the lower end locking claw 28t is locked into the through hole 21h. The boss 28b is formed with a female screw hole 28n.

[0048] The restraining member 29 fixes the upper connecting member 28 (first semi-cylinder member 28A, second semi-cylinder member 28B) to the vertical frame member 21. The restraining member 29 is, for example, a urea screw. The restraining member 29 passes through a screw insertion hole 28h of the first semi-cylinder member 28A and a through hole 21h of the vertical frame member 21, and is fastened to a female screw hole 28n formed in the boss 28b of the second semi-cylinder member 28B. The upper connecting member 28 is configured so that the position of the upper connecting member 28 in the up-down direction Dv with respect to the vertical frame member 21 can be changed by appropriately selecting the lower end locking claw 28t and the through hole 21h for locking or inserting the restraining member 29.

[0049] As shown in FIGS. 3 and 4, in each panel unit 10, between the pair of panel materials 30, a lower opening 30L and an upper opening 30K are formed. The lower opening 30L is formed between the lower end edges 30b (lower sides of the panel outer edge portions 31g) of the pair of panel materials 30 and between the lower brackets 35 (lateral extension portions 35b) facing each other in the first direction Dw. The lower opening 30L has a circular opening 30Lc and a slit-shaped opening Ls. The circular opening 30Lc is formed in the center of the first direction Dw and is formed in a circular shape when viewed from the up-down direction Dv. The circular opening 30Lc is formed at a position where the lower connecting portion 25 faces downward. The slit-shaped openings 30Ls extend from the circular opening 30Lc to both sides in the first direction Dw. The upper opening 30K is formed between the upper edges 30t (upper sides of the panel outer edge portions 31g) of the pair of panel materials 30 and between the upper brackets 35 (lateral extension portions 35b) facing each other in the first direction Dw. The upper opening 30K has a circular opening 30Kc and a slit-shaped opening Ks. The circular opening 30Kc is formed in the center of the first direction Dw and is formed in a circular shape when viewed from the up-down direction Dv. The circular opening 30Kc is formed at a position where the upper connecting portion 26 faces upward. The slit-shaped openings 30Ks extend from the circular opening 30Lc to both sides in the first direction Dw.

[0050] As shown in Figs. 9 to 11, the upper connecting member 28 is configured so that its position in the up-down direction Dv with respect to the vertical frame member 21 can be changed between a stored position P1 and a protruding position P2. 9, in the storage position P1, the upper connecting member 28 is located between the upper edge 30t and the lower edge 30b of the panel material 30, and is stored between the pair of panel materials 30. In the storage position P1, the upper connecting member 28 is disposed below the upper edge 30t of the panel material 30 and above the horizontal frame material 22.

[0051] As shown in FIG. 10 and FIG. 11, in the protruding position P2, the upper connecting member 28 protrudes upward from the upper edge 30t of the panel material 30 through the circular opening 30Kc of the upper opening 30K. In the protruding position P2, the lower end locking claws 28t of the first semi-cylinder member 28A and the second semi-cylinder member 28B are locked in the through holes 21h located at the upper end of the vertical frame material 21. In the protruding position P2, the lower flange portion 27B of the upper connecting member 28 is disposed below the upper edge 30t of the pair of panel materials 30. In the protruding position P2, the upper portion of the upper connecting member 28 protruding upward from the circular opening 30Kc of the upper opening 30K is inserted from below into the circular opening 30Lc of the lower opening 30L of the other panel unit 10 on the upper side. In the protruding position P2, the upper flange portion 27A of the upper connecting member 28 is disposed above the lower edge 30b of the pair of panel materials 30. Therefore, at protruding position P2, the lower portion of the upper connecting member 28 is sandwiched between the pair of panel materials 30 constituting the lower panel unit 10, and the upper portion is sandwiched between the pair of panel materials 30 constituting the upper panel unit 10. In this state, the panel outer edge portion 31g located on the upper edge 30t of the lower panel unit 10 and the panel outer edge portion 31g located on the lower edge 30b of the upper panel unit 10 are inserted between the upper flange portion 27A and the lower flange portion 27B.

[0052] The lower connecting portion 25 is provided at the lower end portion 21b of the vertical frame member 21. The lower connecting portion 25 is configured so as to be insertable into an upper connecting portion 26 (see FIG. 9) of another panel unit 10 arranged below the panel unit 10, or into an upper end portion 72t (see FIG. 10) of a base leg 70 installed on the installation surface F. In the lower connecting portion 25, a plurality of through holes 21h are formed at intervals in the up-down direction Dv below the horizontal frame member 22 in the vertical frame member 21.

[0053] As shown in Figs. 9 and 11, when connecting one panel unit 10 (the upper panel unit in Figs. 9 and 11) to the upper side of another panel unit 10 (the lower panel unit 10 in Figs. 9 and 11), the lower end locking claws 28t of the first semi-cylinder member 28A and the second semi-cylinder member 28B of the upper connecting member 28 are locked to the through holes 21h of the upper end 21t of the vertical frame member 21 of the lower panel unit 10. As a result, the upper connecting member 28 is disposed at a protruding position P2 protruding above the upper end edge 30t of the panel material 30 through the upper opening 30K. In this state, the lower connecting portion 25 (the lower end 21b of the vertical frame member 21) of the panel unit 10 positioned on the upper side is inserted between the first semi-cylinder member 28A and the second semi-cylinder member 28B of the upper connecting member 28 disposed at the protruding position P2. Furthermore, urea screws are fastened as restraining members 29 to the upper connecting member 28 and the lower connecting portion 25 of the other panel unit 10 located above. This connects the other panel unit 10 to the upper side of the one panel unit 10. When viewed from the upper panel unit 10, the upper connecting portion 26 of the other panel unit 10 located below the panel unit 10 is connected to the lower connecting portion 25 of the upper panel unit 10.

[0054] As shown in FIG. 10, when connecting a base leg 70 to be installed on an installation surface F to the lower side of the panel unit 10, the lower connection portion 25 of the panel unit 10 is inserted into a base leg connecting member 74 provided on an upper end portion 72t of the base leg 70. The base leg 70 has a base plate 71 arranged along the installation surface F and a base support 72 extending upward from the base plate 71. The base support 72 is provided with a base leg connecting member 74. A through hole (not shown) is formed in the base support 72. The base leg connecting member 74 has a screw insertion hole through which a fastening member 75 such as a urea screw is inserted, and a female screw hole (not shown). The base leg connecting member 74 is tubular extending in the up-down direction Dv, and the lower connection portion 25 of the panel unit 10 is inserted inside the base leg connecting member 74.

[0055] The lower connecting portion 25 of the panel unit 10, the connecting member 74 for the base leg, and the base support 72 are connected by passing a fastening member 75 through the screw insertion hole of the connecting member 74 for the base leg, the through hole 21h of the lower connecting portion 25, and the through hole of the base support 72, and fastening it to the female screw hole of the connecting member 74 for the base leg.

[0056] <Connection of panel units in the first direction> Fig. 12 is a diagram showing a configuration for connecting the panel units 10 to each other in the first direction Dw. Fig. 13 is a perspective view of the member surface 41f side of the connecting member 40 used to connect the panel units 10 to each other. Fig. 14 is a perspective view of the connecting member 40 from the opposite side to the member surface 41f. Fig. 15 is a view of the connecting member 40 as viewed from the second direction Dt (plate thickness direction). Fig. 16 is a view of the connecting member 40 as viewed from a direction intersecting the second direction Dt. As shown in FIG. 11, the panel unit 10 as described above is configured to be adjacent to another panel unit 10 in the first direction Dw and connectable to the other panel unit 10. The panel unit 10 is connected to the other panel unit 10 adjacent to the first direction Dw via a connecting member 40. In other words, in the panel units 10 adjacent to each other in the first direction Dw, an end of the horizontal frame member 22 of the first panel unit (first panel) 10P on one side in the first direction Dw and an end of the horizontal frame member 22 of the second panel unit (second panel) 10Q on the other side in the first direction Dw are connected via the connecting member 40. As a result, the first panel edge 10f (the edge on the second panel unit 10Q side in the first direction Dw) of the first panel unit 10P and the second panel edge 10g (the edge on the first panel unit 10P side in the first direction Dw) of the second panel unit 10Q are connected via the connecting member 40.

[0057] As shown in Figs. 12 to 16, the connecting member 40 is made of, for example, resin and has a plate-like main body 41. The main body 41 is formed in a substantially circular shape when viewed in its plate thickness direction (the second direction Dt in a state in which the connecting member 40 is aligned with the plate portion 23 of the horizontal frame material 22). When the connecting member 40 connects the first panel unit 10P and the second panel unit 10Q, the connecting member 40 abuts a member surface 41f facing one side of the second direction Dt of the main body 41 against a flat portion 23f (see Fig. 12) of the plate portion 23 of the first panel unit 10P and a flat portion 23f of the plate portion 23 of the second panel unit 10Q. The flat portion 23f is a surface that faces a direction in which the flange portion 24 protrudes in the second direction Dt and intersects with the second direction Dt in each of the plate portion 23 of the first panel unit 10P and the plate portion 23 of the second panel unit 10Q.

[0058] The main body portion 41 integrally includes a first mounting plate portion 42, a second mounting plate portion 43, and a connecting portion 44. The first mounting plate portion 42 is formed in a substantially semicircular shape when viewed from the second direction Dt. A linear edge portion 42a and a semicircular edge portion 42b are formed on the outer edge of the first mounting plate portion 42. The second mounting plate portion 43 is formed in a substantially semicircular shape when viewed from the second direction Dt. A linear edge portion 43a and a semicircular edge portion 43b are formed on the outer edge of the second mounting plate portion 43. The linear edge portion 42a of the first mounting plate portion 42 and the linear edge portion 43a of the second mounting plate portion 43 are arranged in parallel while facing each other. The linear edge portion 42a of the first mounting plate portion 42 and the linear edge portion 43a of the second mounting plate portion 43 are arranged at an interval in a direction along the member surface 41f. As a result, the second mounting plate portion 43 is arranged at a distance from the first mounting plate portion 42.

[0059] The connecting portion 44 is formed between the first mounting plate portion 42 and the second mounting plate portion 43. The connecting portion 44 is formed continuously between the first mounting plate portion 42 and the second mounting plate portion 43 in the direction in which the linear edge portions 42a, 43a extend. The connecting portion 44 connects the first mounting plate portion 42 and the second mounting plate portion 43. The connecting portion 44 has a thickness in the second direction Dt smaller than the plate thicknesses of the first mounting plate portion 42 and the second mounting plate portion 43, and is configured to be elastically deformable. As a result, the connecting portion 44 connects the first mounting plate portion 42 and the second mounting plate portion 43 to be relatively rotatable around the rotation axis 44c along which the connecting portion 44 extends between the first mounting plate portion 42 and the second mounting plate portion 43.

[0060] As will be described in detail later, the connecting member 40 is engaged with and disengaged from the first panel unit 10P and the second panel unit 10Q by rotating it in a circumferential direction Dc around a rotation center 40c located in the center of the main body 41.

[0061] The connecting member 40 includes a first locking portion 45, a second locking portion 46, an outer peripheral extension portion 47, and a holding protrusion 48. As shown in Figs. 13, 15, and 16, the first locking portion 45 and the second locking portion 46 are formed on the member surface 41f side of the main body portion 41. For example, the first locking portions 45 are formed in a plurality of pairs at intervals in the circumferential direction Dc on a concentric circle centered on the rotation center 40c. In this embodiment, the first locking portions 45 are formed in four pairs at equal intervals in the circumferential direction Dc. Two pairs of the first locking portions 45 are formed on each of the first mounting plate portion 42 and the second mounting plate portion 43.

[0062] Each first locking portion 45 has a locking piece 45s. The locking piece 45s extends from the main body 41 toward one side in the circumferential direction Dc and in the second direction Dt. In this embodiment, the locking piece 45s integrally includes a standing portion 45a rising from the member surface 41f, a first arm portion 45b extending from the tip of the standing portion 45a along the member surface 41f toward the first side Dc1 in the circumferential direction Dc (clockwise direction in Figs. 12 and 15), and an inclined portion 45c extending from the tip of the first arm portion 45b in a direction away from the member surface 41f in the second direction Dt. The first arm portion 45b and the member surface 41f of the main body 41 are spaced apart from each other in the second direction Dt by a distance substantially equal to the plate thickness of the plate portion 23. The first arm portion 45b is formed to be elastically deformable in the second direction Dt around the standing portion 45a.

[0063] The second locking portion 46 is formed on the inside in the radial direction with respect to the rotation center 40c with respect to the plurality of first locking portions 45. The second locking portions 46 are formed, for example, in two sets at intervals in the circumferential direction Dc. The second locking portions 46 are formed one by one on each of the first mounting plate portion 42 and the second mounting plate portion 43. Each second locking portion 46 integrally has a second arm portion 46a extending in a cantilever manner from the center of the main body portion 41 toward the outside in the radial direction, and a locking projection 46b formed at the tip end portion of the second arm portion 46a. The second arm portion 46a is formed in the same plane as the main body portion 41. The second arm portion 46a is formed to be elastically deformable in the second direction Dt starting from the base end portion.

[0064] 13 and 15, the outer circumferential extensions 47 are formed on the outer periphery of the main body 41. The outer circumferential extensions 47 are formed in, for example, four sets spaced apart in the circumferential direction Dc. Two sets of the outer circumferential extensions 47 are formed on each of the first mounting plate 42 and the second mounting plate 43. Each outer circumferential extension 47 extends from the outer circumferential edge 41s of the main body 41 in a tangential direction of the outer circumferential edge 41s when viewed from the second direction Dt. As shown in FIG. 14 and FIG. 16, the holding protrusions 48 are formed on the surface 41g of the main body 41 opposite the member surface 41f. The holding protrusions 48 are formed in a pair at a distance in the circumferential direction Dc, for example, at the center of the main body 41. The holding protrusions 48 are formed on each of the first mounting plate 42 and the second mounting plate 43. The holding protrusions 48 protrude from the tip of the second arm 46a to the opposite side to the member surface 41f in the second direction Dt. By gripping the holding protrusions 48, an operator can easily hold the connecting member 40 and rotate the connecting member 40 around the rotation center 40c. In addition, by pulling the pair of holding protrusions 48 from the opposite side to the member surface 41f, the second arm 46a can be elastically deformed, and the locking protrusions 46b protruding from the member surface 41f can be displaced to the opposite surface 41g.

[0065] As shown in Fig. 5, the support structure 20 of each panel unit 10 is formed with connecting member locking portions 50A, 50B to which the connecting member 40 can be locked. The connecting member locking portions 50A, 50B are formed at both ends in the first direction Dw of the plate portion 23. As shown in Fig. 12, when connecting a first panel unit 10P and a second panel unit 10Q, the connecting member 40 is disposed across both the connecting member locking portion 50A of the first panel unit 10P and the connecting member locking portion 50B of the second panel unit 10Q on the other side in the first direction Dw in the panel units 10 adjacent to each other in the first direction Dw.

[0066] As shown in Fig. 5, the connecting member locking portion 50A includes two first locked portions 51A, 51B and two second locked portions 52A, 52B. Two pairs of first locking portions 45 adjacent to each other in the circumferential direction Dc among the four pairs of first locking portions 45 of the connecting member 40 are locked to the two first locked portions 51A, 51B. The two first locked portions 51A, 51B are elongated holes (holes) that penetrate the plate portion 23 in the second direction Dt (plate thickness direction) and extend in an arc shape with a radius of curvature equal to the dimension between the rotation center 40c and the first locking portions 45. One first locked portion 51A opens at a side edge of the horizontal frame member 22. The two second locked portions 52A, 52B are formed on the inside of the first locked portions 51A, 51B. One of the second locked portions 52A is a round hole 52h penetrating the plate portion 23 in the second direction Dt. The other second locked portion 52B is a locking hole 52g consisting of an elongated hole whose major axis is in the first direction Dw.

[0067] The connecting member locking portion 50B includes two first locked portions 51C, 51D and two second locked portions 52C, 52D. The remaining two pairs of first locking portions 45 (the first locking portions 45 other than the first locking portions 45 locked to the first locked portions 51A, 51B) of the four pairs of first locking portions 45 of the connecting member 40 are locked to the two first locked portions 51C, 51D. The two first locked portions 51C, 51D are elongated holes (holes) that penetrate the plate portion 23 in the second direction Dt (plate thickness direction) and extend in an arc shape with a radius of curvature equal to the dimension between the rotation center 40c and the first locking portions 45. One first locked portion 51C opens at the side edge of the horizontal frame member 22. The two second locked portions 52C, 52D are formed on the inside of the first locked portions 51C, 51D. One of the second locked portions 52C is a round hole 52h penetrating the plate portion 23 in the second direction Dt. The other second locked portion 52D is a locking hole 52g consisting of an elongated hole whose major axis is in the first direction Dw.

[0068] 12, the connecting member 40 has four sets of first locking portions 45 locked to the first locked portions 51A and 51B of the first panel unit 10P and the first locked portions 51C and 51D of the second panel unit 10Q. To achieve this, the four sets of first locking portions 45 of the connecting member 40 are inserted inside the first locked portions 51A to 51D along the second direction Dt, and the member surface 41f of the connecting member 40 is brought into contact with the flat surface portion 23f. At this time, the second locking portions 46 are pushed in the second direction Dt by the locking projections 46b hitting the flat surface portion 23f of the plate portion 23.

[0069] FIG. 17 is a diagram showing a locked state Pk in which the first locking portions 45 of the connecting member 40 are locked to the first locked portions 51A to 51D. In this state, as shown in Fig. 17, when the connecting member 40 is rotated relative to the plate portion 23 toward the first side Dc1 in the circumferential direction Dc, a portion 23k of the plate portion 23 located on the first side Dc1 in the circumferential direction Dc with respect to the first locked portions 51A to 51D is inserted between the first arm portion 45b of each first locking portion 45 and the member surface 41f. When the connecting member 40 is further rotated, the standing portion 45a of each first locking portion 45 abuts against the end portion 51e of the first side Dc1 in the circumferential direction Dc of the first locked portions 51A to 51D, resulting in a locked state Pk in which each first locking portion 45 is locked to the first locked portions 51A to 51D. This restricts the rotation of the connecting member 40 relative to the plate portion 23 toward the first side Dc1 in the circumferential direction Dc. At this time, the outer surfaces 47s of the two outer peripheral extensions 47 abut against the flange portions 24 of the horizontal frame material 22. This also restricts the rotation of the connecting member 40 relative to the plate portion 23 toward the first side Dc1 in the circumferential direction Dc.

[0070] When the connecting member 40 is rotated in the circumferential direction Dc, the locking projection 46b of the second locking portion 46 contacts the member surface 41f. When the rising portion 45a of each first locking portion 45 abuts against the end portion 51e of the first side Dc1 in the circumferential direction Dc of the first locked portions 51A to 51D, the locking projection 46b of each second locking portion 46 faces the second locked portions 52A, 52C in the second direction Dt. As a result, the second locking portion 46 is restored and deformed, so that the locking projection 46b fits into the second locked portions 52A, 52C or the second locked portions 52B, 52D. In this way, with each first locking portion 45 locked to the first locked portions 51A to 51D, each second locking portion 46 is locked to each second locked portion 52, and thus the rotation of the connecting member 40 in the circumferential direction Dc is restricted. In this manner, the connecting members 40 are connected to the plate portions 23 of the support structure 20 between the pair of panel materials 30 for each of the first panel unit 10P and the second panel unit 10Q.

[0071] In addition, in the locked state Pk shown in Figure 17, when the pair of retaining protrusions 48 are pulled from the side opposite the component surface 41f, the locking protrusions 46b protruding from the component surface 41f are displaced toward the opposite surface 41g, whereby the locking between each second locking portion 46 and each second locked portion 52 is released.

[0072] FIG. 18 is a diagram showing a disengaged state Pr in which the first locking portions 45 of the connecting member 40 and the first locked portions 51A to 51D are no longer engaged with each other. In this state, as shown in Figure 18, when the connecting member 40 is rotated relative to the plate portion 23 toward the second side Dc2 in the circumferential direction Dc (counterclockwise in Figure 18), the engagement state between each first locking portion 45 and the first locked portions 51A to 51D, and the engagement state between each second locking portion 46 and the second locked portions 52A, 52C transition to a disengaged state Pr.

[0073] In this manner, the connecting member 40 is configured to be able to transition between the locked state Pk and the disengaged state Pr by rotating the connecting member 40 about the rotation center 40c. The connecting member 40 is in the locked state Pk in which the first locking portions 45 are locked to the first locked portions 51A to 51D by rotating the connecting member 40 to the first side Dc1 about the rotation center 40c. The connecting member 40 is in the disengaged state Pr in which the first locking portions 45 are disengaged from the first locked portions 51A to 51D by rotating the connecting member 40 from the locked state Pk to the second side Dc2 about the rotation center 40c.

[0074] The connecting member 40 is configured so that the attachment state of the connecting member 40 to the first panel unit 10P and the second panel unit 10Q can be changed. The connecting member 40 is configured so that the attachment state of the connecting member 40 can be changed between a first configuration S1 (see FIG. 19) and a second configuration S2 (see FIGS. 12 and 17) described below by changing the orientation of the connecting member 40 relative to the first panel unit 10P and the second panel unit 10Q.

[0075] FIG. 19 is a diagram showing a state in which the connecting member 40 is attached to the first panel unit 10P and the second panel unit 10Q in the first configuration S1. As shown in Fig. 19, in the first form S1, the connecting portion 44 is disposed between the first panel edge 10f of the first panel unit 10P and the second panel edge 10g of the second panel unit 10Q. The connecting portion 44 is disposed in a direction in which the first panel edge 10f and the second panel edge 10g extend (vertical direction Dv) intersecting with the arrangement direction (first direction Dw) of the first panel unit 10P and the second panel unit 10Q. In this first form S1, by setting the above-mentioned locking state Pk, the first mounting plate portion 42 is supported by the first panel unit 10P, while the second mounting plate portion 43 is supported by the second panel unit 10Q.

[0076] FIG. 20 is a plan view of the first panel unit 10P and the second panel unit 10Q, to which the connecting member 40 is attached in the first configuration S1, rotated relatively around the rotation axis 44c of the connecting portion 44, as viewed from the vertical direction Dv. 20, in the first configuration S1, the first panel unit 10P and the second panel unit 10Q are relatively rotatable about the rotation axis 44c of the connecting portion 44 together with the first mounting plate portion 42 and the second mounting plate portion 43. This allows the angle θ between the first panel unit 10P and the second panel unit 10Q to be adjusted arbitrarily. Note that in this embodiment, the angle θ between the first panel unit 10P and the second panel unit 10Q refers to the angle formed between the first mounting plate portion 42 and the second mounting plate portion 43 with the connecting portion 44 in between.

[0077] 19, in the first form S1, in the locked state Pk, the locking projection 46b fits into the second locked portions 52B, 52D consisting of the locking holes 52g (long holes). As a result, the locking projection 46b is locked to the second locked portions 52B, 52D in a state in which the first panel unit 10P and the second panel unit 10Q can be displaced relative to each other in the arrangement direction (first direction Dw). Therefore, the distance between the first panel unit 10P and the second panel unit 10Q in the arrangement direction (first direction Dw) is changeable. In the first form S1, when the first panel unit 10P and the second panel unit 10Q, together with the first mounting plate portion 42 and the second mounting plate portion 43, are rotated relatively around the pivot axis 44c of the connecting portion 44, and the angle θ between the first panel unit 10P and the second panel unit 10Q is set to 180° or less, interference between the first panel edge 10f of the first panel unit 10P and the second panel edge 10g of the second panel unit 10Q can be suppressed.

[0078] As shown in FIG. 17, in the second form S2, the connecting portion 44 is arranged to extend in a direction different from that of the first form S1. In this embodiment, the connecting portion 44 (axial direction of the pivot shaft 44c) is arranged along the arrangement direction (first direction Dw). The connecting portion 44 extends across the first panel unit 10P and the second panel unit 10Q. As a result, the connecting portion 44 is arranged to overlap both the first panel unit 10P and the second panel unit 10Q when viewed from the second direction Dt. In the second form S2, the first mounting plate portion 42 and the second mounting plate portion 43 are arranged across both the first panel unit 10P and the second panel unit 10Q. In the second form S2, in the locked state Pk, one end portion 42s, 43s of each of the first mounting plate portion 42 and the second mounting plate portion 43 in the axial direction of the pivot shaft 44c (first direction Dw in the second form S2) is supported by the first panel unit 10P. In addition, in the second form S2, in the locked state Pk, the other ends 42t, 43t of the first mounting plate portion 42 and the second mounting plate portion 43 in the axial direction of the pivot shaft 44c (first direction Dw in the second form S2) are supported by the second panel unit 10Q.

[0079] FIG. 21 is a plan view showing a state in which the first panel unit 10P and the second panel unit 10Q to which the connecting members 40 are attached in the second configuration S2 are arranged in a straight line when viewed from the up-down direction Dv. In the second form S2, the first mounting plate portion 42 and the second mounting plate portion 43 are disposed straddling the first panel unit 10P and the second panel unit 10Q in the first direction Dw, and are supported by the first panel unit 10P and the second panel unit 10Q, respectively. As a result, as shown in Fig. 21, the first panel unit 10P and the second panel unit 10Q are fixed in a state along both the first mounting plate portion 42 and the second mounting plate portion 43, and are disposed in a straight line (angle θ is 180°) along the first direction Dw in a plan view from the up-down direction Dv.

[0080] 17, in the second form S2, in the locked state Pk, the locking projection 46b fits into the second locked portions 52A, 52C consisting of the round holes 52h. This prevents the locking projection 46b from displacing the first panel unit 10P and the second panel unit 10Q relative to the second locked portions 52A, 52C in the arrangement direction (first direction Dw). Therefore, the connecting member 40 is firmly connected to the first panel unit 10P and the second panel unit 10Q, and firmly maintains the state in which the first panel unit 10P and the second panel unit 10Q are linearly arranged along the first direction Dw in a plan view from the up-down direction Dv.

[0081] Fig. 22 is a plan view showing the closing member 80 provided in the panel unit 10. Fig. 23 is a front view showing the closing member 80. As shown in Fig. 22, the panel unit 10 includes a blocking member 80 capable of blocking the upper opening 30K. As shown in Figs. 22 and 23, the blocking member 80 integrally includes a blocking portion 81 and a boss portion 82. The blocking portion 81 integrally includes a first blocking portion 81a that blocks the circular opening 30Kc of the upper opening 30K, and a second blocking portion 81b that extends from the first blocking portion 81a on both sides in the first direction Dw and blocks the slit-shaped opening 30Ks of the upper opening 30K. The boss portion 82 is inserted into the upper opening 30K when the blocking member 80 is attached to the upper opening 30K.

[0082] As shown in Fig. 5, the above-mentioned connecting member 40 and closing member 80 can be stored in the panel unit 10 when not in use. The connecting member 40 and closing member 80 are attached to the support structure 20 when not in use. For this reason, as shown in Fig. 3, the support structure 20 is provided with a connecting member holding portion 91 and a closing member holding portion 92 in a portion covered by the panel material 30 (a portion overlapping with the panel material 30 when viewed from the second direction Dt). The connecting member holding portion 91 and the closing member holding portion 92 are formed in the plate portion 23 of the horizontal frame material 22. The connecting member holding portion 91 and the closing member holding portion 92 are formed on both sides of the vertical frame material 21 in the first direction Dw.

[0083] The connecting member holding portion 91 has a first retaining hole 91a in which the first locking portion 45 of the connecting member 40 can be locked, and a second retaining hole 91b in which the second locking portion 46 can be locked. The connecting member holding portion 91 can lock the connecting member 40 in the first retaining hole 91a and the second retaining hole 91b by rotating the connecting member 40 to a first side Dc1 (see FIG. 15) in the circumferential direction Dc, similar to when the first locking portion 45 and the second locking portion 46 are attached to the connecting member locking portions 50A and 50B. In addition, the connecting member holding portion 91 can release the locking of the first locking portion 45 and the second locking portion 46 of the connecting member 40 to the first retaining hole 91a and the second retaining hole 91b by rotating the connecting member 40 to a second side Dc2 (see FIG. 15) in the circumferential direction Dc.

[0084] The closing member holding portion 92 is formed in the center of the connecting member holding portion 91. The closing member holding portion 92 is fitted onto the boss portion 82 of the closing member 80, so that the closing member 80 is removably attached when not in use.

[0085] <Partition device> By using one or more panel units 10 as described above, partition devices of various shapes can be constructed. FIG. 24 is a diagram showing a partition device 1 configured using the panel unit 10. As shown in FIG. As shown in Fig. 24, the partition device 1 is installed on an installation surface F facing upward, and is used to partition an indoor space formed above the installation surface F in the second direction Dt. The partition device 1 is configured, for example, by stacking a plurality of panel units 10 in a plurality of stages in the vertical direction Dv, and connecting the panel units 10 in a plurality of rows in the first direction Dw in each stage in the vertical direction Dv. In this embodiment, a total of six panel units 10 are connected, with two rows in the first direction Dw and three rows vertically.

[0086] The partition device 1 includes, in each row in the first direction Dw, three panel units 10, for example, connected in the vertical direction Dv on base legs 70 installed on an installation surface F. The panel units 10 positioned above and below each other are connected to each other by the lower connecting portions 25 and upper connecting portions 26 as described above. Here, the number of panel units 10 stacked vertically is not limited to three, but can be increased or decreased as appropriate.

[0087] In each row in the up-down direction Dv, the first panel unit 10P arranged in a row on one side in the first direction Dw and the second panel unit 10Q arranged in a row on the other side in the first direction Dw have their horizontal frame members 22 connected to each other by the connecting member 40. In this case, as shown in Fig. 21, if the first panel unit 10P and the second panel unit 10Q are arranged in a straight line in a plan view seen from the up-down direction Dv, the connecting member 40 is attached to the first panel unit 10P and the second panel unit 10Q as shown in Fig. 20 with the mounting state being the second form S2 (see Fig. 19). Furthermore, if the first panel unit 10P and the second panel unit 10Q are arranged such that the angle θ between the first panel unit 10P and the second panel unit 10Q is bent to 180° or less when viewed in a plan view from the vertical direction Dv at the connecting portion between the first panel unit 10P and the second panel unit 10Q, the connecting member 40 is attached to the first panel unit 10P and the second panel unit 10Q with the mounting state being the above-mentioned first form S1 (see Figure 17).

[0088] To assemble the partition device 1 as described above, with the panel material 30 removed from each panel unit 10, adjacent panel units 10 in the first direction Dw are connected to each other using the connecting members 40, and upper and lower panel units 10 are connected to each other using the lower connecting parts 25 and upper connecting parts 26. After that, the pair of panel materials 30 are joined to each other by connecting the brackets 35. At this time, adjacent panel units 10 in the first direction Dw are connected to each other by rotating the connecting member 40. Furthermore, the upper and lower panel units 10 are connected to each other using the lower connecting portion 25 and the upper connecting portion 26 by engaging the upper connecting portion 26 with the vertical frame member 21 and tightening the restraining member 29 using a urea screw. Furthermore, a pair of panel members 30 are connected to each other by connecting the brackets 35 to each other. Therefore, the assembly of each panel unit 10 and the connection of the panel units 10 to each other can be easily performed manually without tools.

[0089] Furthermore, when removing a panel unit 10 or changing the combination of panel units 10, the above-mentioned assembly method is performed in reverse. That is, first, for the panel unit 10 to be removed (target panel unit 10) and the panel unit 10 (connected panel unit 10) connected to the target panel unit 10, the connection between the pair of panel materials 30 via the brackets 35 is released to expose the support structure 20. Next, the connection by the connecting member 40 or the connection by the upper connecting portion 26 (lower connecting portion 25) between the target panel unit 10 and the support structure 20 of the connected panel unit 10 is released. This allows the support structure 20 of the target panel unit 10 to be removed from the support structure 20 of the connected panel unit 10.

[0090] In this manner, in the partition device 1 of the present embodiment, the first configuration S1 is realized by arranging the connecting member 40 so that the connecting portion 44 is disposed between the first panel unit 10P and the second panel unit 10Q, one of the first mounting plate portions 42 is supported by the first panel unit 10P, and the other first mounting plate portion 42 is supported by the second panel unit 10Q. In the first configuration S1, the first panel unit 10P and the second panel unit 10Q can rotate relatively around the rotation axis 44c of the connecting portion 44 together with the first mounting plate portion 42 and the second mounting plate portion 43. This makes it possible to arbitrarily adjust the angle θ between the first panel unit 10P and the second panel unit 10Q without preparing multiple types of connecting members 40 that correspond to the angle between the first panel unit 10P and the second panel unit 10Q. As a result, the effort and cost required to change the angle between the first panel unit 10P and the second panel unit 10Q can be reduced. In the second form S2, both the first mounting plate portion 42 and the second mounting plate portion 43 are supported straddling both the first panel unit 10P and the second panel unit 10Q. As a result, in a state in which the first panel unit 10P and the second panel unit 10Q are linearly arranged in the first direction Dw, the relative displacement between the first panel unit 10P and the second panel unit 10Q in a direction that increases or decreases the angle between the first panel unit 10P and the second panel unit 10Q is regulated by at least one of the first mounting plate portion 42 and the second mounting plate portion 43. As a result, the first panel unit 10P and the second panel unit 10Q can be firmly connected in a state in which they are linearly arranged. Therefore, there is no need to use different connecting members 40 for the first configuration S1 and the second configuration S2. By simply changing the mounting state of the same connecting member 40, the angle between the panels can be easily changed.

[0091] In this embodiment, in the second configuration S2, both the first mounting plate portion 42 and the second mounting plate portion 43 are configured to be supported across the first panel unit 10P and the second panel unit 10Q. According to this configuration, the first mounting plate portion 42 and the second mounting plate portion 43 are supported by the first panel unit 10P and the second panel unit 10Q in a state in which they are arranged so as to straddle the first panel unit 10P and the second panel unit 10Q, respectively. As a result, in a state in which the first panel unit 10P and the second panel unit 10Q are arranged linearly in the first direction Dw, the relative displacement between the first panel unit 10P and the second panel unit 10Q in a direction that increases or decreases the angle between the first panel unit 10P and the second panel unit 10Q is restricted by both the first mounting plate portion 42 and the second mounting plate portion 43. The connecting member 40 can easily change the mounting state of the connecting member 40 between the first form S1 and the second form S2 by changing the direction around the rotation center 40c.

[0092] In this embodiment, the connecting members 40 are configured to connect the first panel unit 10P and the second panel unit 10Q to the support structure 20 between the pair of panel materials 30. This configuration prevents the attachment portions of the connecting member 40 to the first panel unit 10P and the second panel unit 10Q from being exposed to the outside. Furthermore, by connecting the connecting member 40 to the support structure 20, the first panel unit 10P and the second panel unit 10Q are firmly connected to each other.

[0093] In this embodiment, the first panel unit 10P and the second panel unit 10Q each have a planar portion 23f, and the connecting member 40 is configured to be connected to the first panel unit 10P and the second panel unit 10Q while abutting against the planar portion 23f. According to this configuration, the connecting member 40 is abutted against the planar portions 23f of the first panel unit 10P and the second panel unit 10Q, thereby firmly connecting the connecting member 40 to each of the first panel unit 10P and the second panel unit 10Q.

[0094] In this embodiment, a locking hole 52g is formed in the planar portion 23f, and a locking protrusion 46b capable of engaging with the locking hole 52g is formed in the connecting member 40, and the locking protrusion 46b is configured to be engaged with the locking hole 52g in a state in which the first panel unit 10P and the second panel unit 10Q can be displaced relatively in the first direction Dw. According to this configuration, the locking hole 52g is locked with the locking protrusion 46b, so that the connecting member 40 can be connected to the first panel unit 10P and the second panel unit 10Q. The locking protrusion 46b allows the first panel unit 10P and the second panel unit 10Q to be displaced relative to the locking hole 52g in the first direction Dw, so that the distance between the first panel unit 10P and the second panel unit 10Q in the first direction Dw can be changed. This makes it possible to prevent the ends of the first panel unit 10P and the second panel unit 10Q from interfering with each other when the first panel unit 10P and the second panel unit 10Q are rotated relatively to each other around the rotation shaft 44c of the connecting portion 44 together with the first mounting plate portion 42 and the second mounting plate portion 43 in the first form S1 to adjust the angle θ between the first panel unit 10P and the second panel unit 10Q.

[0095] The partition device 1 of this embodiment is capable of partitioning an indoor space formed above the installation surface F by installing the first panel unit 10P and the second panel unit 10Q on an installation surface F facing upward and arranging the first panel unit 10P and the second panel unit 10Q side by side in a direction along the installation surface F. In such a partition device 1, by changing the attachment state of the connecting members 40 to the first panel unit 10P and the second panel unit 10Q, it is possible to provide a partition device 1 that makes it possible to easily change the angle θ between the panels without preparing multiple types of connecting members 40.

[0096] Second embodiment Next, a second embodiment of the panel system and partition device according to the present invention will be described. In the second embodiment described below, the same reference numerals are given to the components common to the first embodiment, and the description thereof will be omitted. Fig. 25 is a diagram showing a configuration for connecting the panel units 10 to each other in the first direction Dw. Fig. 26 is a perspective view of a member surface 61f side of a connecting member 60 used to connect the panel units 10 to each other. Fig. 27 is a perspective view of the connecting member 60 on the opposite side to the member surface 61f. As shown in FIG. 25, a first panel unit 10P and a second panel unit 10Q that are adjacent to each other in the first direction Dw are connected via a connecting member 60.

[0097] As shown in Figs. 25 to 27, the connecting member 60 is made of, for example, resin and includes a plate-shaped main body 61. The main body 61 is formed in a rectangular shape when viewed in its plate thickness direction (the second direction Dt in a state in which the connecting member 60 is aligned with the plate portion 23 of the horizontal frame material 22). When viewed in the second direction Dt, the main body 61 is formed in a rectangular shape with the first direction Dw as the long side direction and the up-down direction Dv as the short side direction. When the connecting member 60 connects the first panel unit 10P and the second panel unit 10Q, the connecting member 60 abuts a member surface 61f of the main body 61 facing one side in the second direction Dt against the flat portion 23f (see Fig. 25) of the plate portion 23 of the first panel unit 10P and the flat portion 23f of the plate portion 23 of the second panel unit 10Q. The planar portion 23f is a surface that faces the other side of the second direction Dt and intersects with the second direction Dt in each of the plate portion 23 of the first panel unit 10P and the plate portion 23 of the second panel unit 10Q.

[0098] The main body portion 61 integrally includes a first mounting plate portion 62, a second mounting plate portion 63, and a connecting portion 64. The first mounting plate 62 is formed in a vertically long rectangular shape with the long side direction being the up-down direction Dv and the short side direction being the first direction Dw when viewed from the second direction Dt. The second mounting plate 63 is formed in a substantially square shape when viewed from the second direction Dt. As shown in Fig. 27, in this embodiment, the width dimension W2 of the second mounting plate 63 in the first direction Dw is set to be approximately twice the width dimension W1 of the first mounting plate 62 in the first direction Dw. An edge 62a on the other side in the first direction Dw of the first mounting plate portion 62 and an edge 63a on one side in the first direction Dw of the second mounting plate portion 63 each extend in the up-down direction Dv and are disposed parallel to each other. The edge 62a of the first mounting plate portion 62 and the edge 63a of the second mounting plate portion 63 are disposed at an interval in the first direction Dw. As a result, the second mounting plate portion 63 is disposed at a distance from the first mounting plate portion 62 in the first direction Dw.

[0099] The connecting portion 64 is formed between the first mounting plate portion 62 and the second mounting plate portion 63. The connecting portion 64 extends continuously in the up-down direction Dv between the edge portion 62a of the first mounting plate portion 62 and the edge portion 63a of the second mounting plate portion 63. The connecting portion 64 connects the first mounting plate portion 62 and the second mounting plate portion 63. The connecting portion 64 has a thickness in the second direction Dt smaller than the plate thicknesses of the first mounting plate portion 62 and the second mounting plate portion 63, and is configured to be elastically deformable. As a result, the connecting portion 64 connects the first mounting plate portion 62 and the second mounting plate portion 63 to be relatively rotatable around the rotation axis 64c along which the connecting portion 64 extends between the first mounting plate portion 62 and the second mounting plate portion 63.

[0100] The connecting member 60 includes locking projections 65. The locking projections 65 are formed in a pair with a gap therebetween in the up-down direction Dv. In this embodiment, one set of the pair of locking projections 65 is disposed on the first mounting plate portion 62. Two sets of the pair of locking projections 65 are formed on the second mounting plate portion 63 with a gap therebetween in the first direction Dw.

[0101] As shown in Figures 26 and 27, each locking projection 65 includes a frame portion 66 and a locking piece 67. As shown in Figure 26, the frame portion 66 is formed on a member surface 61f of the main body portion 61. The frame portion 66 protrudes from the member surface 61f in the second direction Dt. When viewed from the second direction Dt, the frame portion 66 integrally includes a first wall portion 66a extending in the first direction Dw, and a pair of second wall portions 66b extending in the up-down direction Dv from both ends of the first wall portion 66a in the first direction Dw. 27, the locking piece 67 integrally includes a base 67a protruding from a surface 61g of the main body 61 facing the opposite side to the member surface 61f, and a folded-back piece 67b folded back at the tip of the base 67a and passing through an opening 61k formed in the main body 61. A tip 67t of the folded-back piece 67b is disposed at substantially the same position as a tip 66t of the frame 66 in the second direction Dt. An engagement claw 67s that engages with a locking hole 58 described later is formed on the folded-back piece 67b. The folded-back piece 67b of the locking piece 67 is formed so as to be elastically deformable in a direction approaching and separating from the first wall portion 66a of the frame portion 66 in the up-down direction Dv.

[0102] As shown in Fig. 25, the support structure 20 of each panel unit 10 is formed with locking holes 58 into which the connecting members 60 can be locked. The locking holes 58 are formed in the plate portion 23. The locking holes 58 are formed in a pair with a gap therebetween in the up-down direction Dv. A plurality of pairs of locking holes 58 are formed with a gap therebetween in the first direction Dw. When viewed from the second direction Dt, each of the locking holes 58 is formed in a horizontally long rectangular shape whose longer side direction is the first direction Dw and whose shorter side direction is the up-down direction Dv.

[0103] The connecting member 60 is attached to the plate portion 23 by engaging each of the locking projections 65 with the locking holes 58. To engage each of the locking projections 65 with the locking holes 58, the locking projections 65 are inserted into the locking holes 58, and the member surface 61f of the connecting member 60 is abutted against the flat portion 23f. In this state, the frame portion 66 and the tip portion of the folded piece 67b are inserted into the locking hole 58. In the locking hole 58, at least the first wall portion 66a of the frame portion 66 abuts against an edge portion located on one side of the locking hole 58 in the vertical direction Dv, and the folded piece 67b abuts against an edge portion located on the other side of the locking hole 58 in the vertical direction Dv. The engaging claw 67s formed on the folded piece 67b engages with the plate portion 23 at the outer edge portion of the locking hole 58, and prevents the locking projection 65 from falling out of the locking hole 58. The connecting member 60 causes all of the locking projections 65 formed on the first mounting plate portion 62 and the second mounting plate portion 63 to engage with the locking holes 58 of the plate portion 23 . Furthermore, when removing the connecting member 60 from the plate portion 23, after removing the panel material 30, the tip of the folded piece 67b of each locking projection 65 is pressed toward the first wall portion 66a. This releases the engagement of the engagement claws 67s with the plate portion 23, making it possible to pull out the locking projections 65 from the locking holes 58. By performing the same disengagement operation on all of the locking projections 65, the connecting member 60 can be removed from the plate portion 23.

[0104] The connecting member 60 is configured so that the attachment state of the connecting member 60 to the first panel unit 10P and the second panel unit 10Q can be changed. The connecting member 60 is configured so that the attachment state of the connecting member 60 can be changed between a first form S11 (see FIG. 28) and a second form S12 (see FIG. 29) described below by changing the position in the first direction Dw relative to the first panel unit 10P and the second panel unit 10Q.

[0105] 13 is a diagram showing a state in which the connecting member 60 is in a first configuration S11, connecting a first panel unit 10P and a second panel unit 10Q. As shown in FIG. 28, in the first form S11, the connecting portion 64 is disposed between the first panel edge 10f of the first panel unit 10P and the second panel edge 10g of the second panel unit 10Q. The connecting portion 64 is disposed in a direction (vertical direction Dv) in which the first panel edge 10f and the second panel edge 10g extend, intersecting with the arrangement direction (first direction Dw) of the first panel unit 10P and the second panel unit 10Q. In this first form S11, each locking protrusion 65 of the first mounting plate portion 62 is locked to each of the two locking holes 58 of the first panel unit 10P. Each locking protrusion 65 of the second mounting plate portion 63 is locked to each of the four locking holes 58 of the second panel unit 10Q. In this way, the first mounting plate portion 62 is supported by the first panel unit 10P, while the second mounting plate portion 63 is supported by the second panel unit 10Q.

[0106] In the first form S11, the connecting portion 64 is arranged between the first panel edge 10f of the first panel unit 10P and the second panel edge 10g of the second panel unit 10Q, so that the first panel unit 10P and the second panel unit 10Q can be rotated relatively around the pivot axis 64c of the connecting portion 64, thereby allowing the angle θ between the first panel unit 10P and the second panel unit 10Q to be adjusted arbitrarily.

[0107] FIG. 29 is a diagram showing a state in which the connecting member 60 is in the second configuration S12, connecting the first panel unit 10P and the second panel unit 10Q. 29, in the second configuration S12, the connecting member 60 is slid in the first direction Dw with respect to the first configuration S11, and the second mounting plate portion 63 is disposed straddling both the first panel unit 10P and the second panel unit 10Q. A total of four locking projections 65 provided on the first mounting plate portion 62 are locked into two locking holes 58 on the first panel unit 10P side and two locking holes 58 on the second panel unit 10Q side, respectively. As a result, the second mounting plate portion 63 is supported straddling both the first panel unit 10P and the second panel unit 10Q. In the second configuration S12, the first mounting plate portion 62 and the connecting portion 64 overlap the planar portion 23f of the first panel unit 10P when viewed from the second direction Dt. The pair of locking projections 65 of the first mounting plate portion 62 are locked into the two locking holes 58 of the first panel unit 10P.

[0108] Thus, in the partition device 1 of this embodiment, the connecting member 60 connecting the first panel unit 10P and the second panel unit 10Q has a connecting portion 64 arranged between the first panel unit 10P and the second panel unit 10Q, and the mounting state of the connecting member 60 relative to the first panel unit 10P and the second panel unit 10Q can be changed between a first configuration S11 in which the first mounting plate portion 62 is supported by the first panel unit 10P while the second mounting plate portion 63 is supported by the second panel unit 10Q, and a second configuration S12 in which the second mounting plate portion 63 is supported across the first panel unit 10P and the second panel unit 10Q. According to this configuration, the angle between the first panel unit 10P and the second panel unit 10Q can be arbitrarily adjusted by changing the attachment state of the connecting member 60, without having to prepare multiple types of connecting members 60 that match the angle. As a result, it is possible to reduce the effort and cost required to change the angle between the first panel unit 10P and the second panel unit 10Q. In the second form S12, at least one of the first mounting plate portion 62 and the second mounting plate portion 63 is supported across both the first panel unit 10P and the second panel unit 10Q. This allows the first panel unit 10P and the second panel unit 10Q to be firmly connected in a state where they are linearly arranged. Therefore, by simply changing the mounting state of the same connecting member 60, it is possible to easily change the angle between the panels without having to prepare multiple types of connecting members 60.

[0109] In this embodiment, in the second configuration S12, the second mounting plate portion 63 is supported across the first panel unit 10P and the second panel unit 10Q, the first mounting plate portion 62 is supported by the first panel unit 10P, and the connecting portion 64 is positioned overlapping the first panel unit 10P. According to this configuration, the second mounting plate portion 63 is supported across the first panel unit 10P and the second panel unit 10Q, so that in a state in which the first panel unit 10P and the second panel unit 10Q are linearly arranged in the first direction Dw, the relative displacement between the first panel unit 10P and the second panel unit 10Q in a direction that increases or decreases the angle between the first panel unit 10P and the second panel unit 10Q is regulated by the second mounting plate portion 63. By changing the mounting position of the connecting member 60 relative to the first panel unit 10P and the second panel unit 10Q, it is possible to switch between the first configuration S11 and the second configuration S12, so that the mounting state of the connecting member 60 can be easily changed between the first configuration S11 and the second configuration S12.

[0110] (Other embodiments) Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the scope of the attached claims. For example, in the above-described embodiment, the connecting members 40, 60 are connected in a state where they are in contact with the flat surface portions 23f formed on the horizontal frame members 22 of the first panel unit 10P and the second panel unit 10Q, but this is not limited thereto. The connecting members 40, 60 may be connected in a state where they are in contact with the flat surface portions of the panel surfaces of the first panel unit 10P and the second panel unit 10Q. In addition, the first panel unit 10P and the second panel unit 10Q are configured to sandwich the support structure 20 between a pair of panel materials 30, but this is not limited thereto. As long as the connecting members 40, 60 are in contact with the flat surface portions, the first panel and the second panel may be, for example, simply plate-shaped.

[0111] In the above embodiment, the first panel unit 10P and the second panel unit 10Q constituting the partition device 1 are connected by the connecting members 40, 60, but the present invention is not limited to this.

[0112] The arrangement direction of the first panel unit 10P and the second panel unit 10Q connected by the connecting members 40, 60 may be other directions, such as the vertical direction Dv. For example, when the first panel unit 10P and the second panel unit 10Q are arranged in the vertical direction Dv, the vertical direction Dv becomes the first direction, and the left-right direction intersecting the vertical direction Dv becomes the intersecting direction in which the rotation axis extends.

[0113] In addition, in the above embodiment, the connecting members 40, 60 are arranged only in the middle of the first panel unit 10P and the second panel unit 10Q in the vertical direction Dv, but the connecting members 40, 60 may be provided at multiple locations in the vertical direction Dv. Furthermore, the connecting members 40, 60 are made of resin and integrally include the first mounting plate portion 42, the second mounting plate portion 43, and the connecting portion 44, but are not limited to this. The connecting members 40, 60 may be configured by combining the first mounting plate portion 42, the second mounting plate portion 43, and the connecting portion 44 with separate parts, or may be made of other materials such as metal.

[0114] In the above embodiment, the first locking portion 45 and the second locking portion 46 are formed on the main body 41, and the first locked portions 51A-51D and the second locked portions 52A-52D are formed on the flat surface portion 23f, but this is not limited thereto. For example, the first locked portions 51A-51D and the second locked portions 52A-52D may be formed on the main body 41, and the first locking portion 45 and the second locking portion 46 may be formed on the flat surface portion 23f.

[0115] In the above embodiment, the configuration of each part of the panel unit 10 has been described as including the support structure 20, a pair of panel materials 30, a lower connecting portion 25, an upper connecting portion 26, etc., but the configuration of each part of the panel unit 10 can be changed to other configurations as appropriate. In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate.
