Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the configuration as disclosed in Patent Document 1, the connecting members are fixed to each panel by screws. Therefore, when assembling the partitioning device, in order to connect the panels by the connecting members, the screws must be tightened using tools, which is time-consuming. An object of the present invention is to provide a panel system and a partitioning device that can be easily assembled.

Means for Solving the Problems

[0005] In order to achieve the above object, a panel unit according to one aspect of the present invention includes a plate-shaped first panel, a plate-shaped second panel provided side by side with the first panel in a first direction, and a connecting member that connects the first panel and the second panel. The first panel and the second panel each have a flat surface portion that intersects the thickness direction of the first panel and the second panel. The connecting member has a main body portion having a member surface that abuts against the flat surface portion. A first engaged portion is formed on either the main body portion or the flat surface portion. A first locking portion that can be locked to the first engaged portion is formed on the other of the connecting member and the flat surface portion by rotating the connecting member around a rotation center on one side in a direction intersecting the member surface.

[0006] In this way, when the connecting member is rotated to one side around the rotation center with the member surface of the connecting member in contact with the flat surface portions of the first panel and the second panel, the first locking portion is locked to the first engaged portion. In this manner, the connecting member is connected to the first panel and the second panel, and the first panel and the second panel are connected by the connecting member. Therefore, when connecting the first panel and the second panel by the connecting member, it is not necessary to use a tool to tighten a screw. As a result, the assembly of the panel unit can be easily performed.

[0007] In the panel unit according to one aspect of the present invention, the connecting member may be configured to be movable between a locked state in which the first locking portion is locked to the first engaged portion by rotating the connecting member to one side around the rotation center, and a released state in which the first locking portion is disengaged from the first engaged portion by rotating the connecting member to the other side around the rotation center from the locked state. According to this configuration, when the connecting member is rotated to one side around the rotation center, the first locking portion is locked to the first locked portion and enters a locked state. Thereby, the connecting member can be connected to the flat portions of the first panel and the second panel. Further, when the connecting member is rotated to the other side around the rotation center, the first locking portion that was locked to the first locked portion in the locked state disengages from the first locked portion. Thereby, the connecting member can be shifted from the locked state to the disengaged state, and the connecting member can be removed from the first panel and the second panel. In this way, by simply switching the rotation direction of the connecting member, the connection of the connecting member to the first panel and the second panel and the removal of the connecting member from the first panel and the second panel can be easily performed.

[0008] In the panel unit according to one aspect of the present invention, the first locked portion may be formed to extend in the circumferential direction around the rotation center, and when the first locking portion is inserted into the first locked portion and rotated by an angle defined around the rotation center, the first locking portion may be locked to the first locked portion by hitting the end portion on the first side around the rotation center of the first locked portion. According to this configuration, when the connecting member is rotated by an angle defined on one side around the rotation center, the operator can easily and surely recognize that the first locking portion has hit the end portion on the first side around the rotation center of the first locked portion, and thus the first locking portion has been locked to the first locked portion and has shifted to the locked state.

[0009] In the panel unit according to one aspect of the present invention, the first locked portion may be a hole formed in the flat portion, and the first locking portion may include a locking piece that extends from the main body portion in the direction around the rotation center and in the plate thickness direction of the main body portion. According to this configuration, after inserting the locking piece of the first locking portion into the hole as the first locked portion in the plate thickness direction, when the connecting member is rotated to one side around the rotation center, a flat portion enters between the locking piece and the main body portion, and the first locking portion is locked to the first locked portion. In this way, it becomes possible to connect the connecting member to the first panel and the second panel with a locking piece having a simple configuration.

[0010] In the panel unit according to one aspect of the present invention, a second locked portion is formed on either one of the main body portion and the flat portion, and the connecting member and the other one of the flat portions are rotated around the rotation center extending in a direction intersecting the member surface, and in a state where the first locking portion is locked to the first locked portion, a second locking portion that locks to the second locked portion may be formed to restrict rotation of the connecting member around the rotation center. According to this configuration, when the connecting member is rotated around the rotation center and the second locking portion is locked to the second locked portion in a state where the first locking portion is locked to the first locked portion, rotation of the connecting member around the rotation center is restricted. As a result, the first locking portion is restricted in a state of being locked to the first locked portion, and it is possible to prevent the connecting member from being inadvertently detached from the first panel and the second panel.

[0011] In the panel unit according to one aspect of the present invention, the first panel and the second panel each include a pair of panel members and a support structure sandwiched between the pair of panel members and having the flat portion, and the connecting member may be connected to the flat portion of the support structure between the pair of panel members 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 members with respect to the flat portions of the first panel and the second panel, so that the attachment portions of the connecting member to the first panel and the second panel are suppressed from being exposed to the outside. Further, by connecting the connecting member to the support structure, the first panel and the second panel are firmly connected.

[0012] In a panel unit according to an aspect of the present invention, the connecting member includes a first mounting plate portion, a second mounting plate portion disposed apart from the first mounting plate portion, and a connecting portion that rotatably connects the first mounting plate portion and the second mounting plate portion relative to each other around a rotation axis extending between the first mounting plate portion and the second mounting plate portion. The connecting member has a first form in which the connecting portion is disposed between the first panel and the second panel, the first mounting plate portion is supported by the first panel, and the second mounting plate portion is supported by the second panel, and a second form in which the connecting portion is disposed so as to straddle the first panel and the second panel along the first direction with the axial direction of the rotation axis arranged along the first direction, and both the first mounting plate portion and the second mounting plate portion are supported so as to straddle the first panel and the second panel. The mounting state of the connecting member with respect to the first panel and the second panel may be made changeable. According to this configuration, the first form of the connecting member is realized by disposing the connecting portion between the first panel and the second panel, supporting one first mounting plate portion by the first panel, and supporting the other first mounting plate portion by the second panel. In the first form, the first panel and the second panel can be relatively rotated about the rotation axis of the connecting portion together with the first mounting plate portion and the second mounting plate portion. Thereby, the angle formed by the first panel and the second panel can be arbitrarily adjusted. Further, in the second form, the first mounting plate portion and the second mounting plate portion are disposed so as to straddle the first panel and the second panel, respectively, and are supported by each of the first panel and the second panel. As a result, the first panel and the second panel are fixed in a state along at least one of the first mounting plate portion and the second mounting plate portion. The first panel and the second panel are constrained to be linearly arranged. Therefore, there is no need to use different connecting members for the first form and the second form, and both the first form and the second form can be realized only by changing the orientation of the same connecting member. As a result, the angle formed by the panels can be easily changed, and when the panels are arranged linearly, it is possible to reliably maintain the state where the panels are arranged linearly.

[0013] The partition device according to the present invention includes the panel system as described above.

[0014] In this way, by installing the first panel and the second panel on the installation surface facing upward respectively, and arranging the first panel and the second panel side by side in the direction along the installation surface, the indoor space formed above the installation surface can be partitioned. In such a partition device, with the member surface of the connecting member in contact with the flat portions of the first panel and the second panel, by rotating the connecting member to one side around the rotation center, the connecting member is connected to the first panel and the second panel, and the first panel and the second panel are connected by the connecting member. Therefore, when connecting the first panel and the second panel by the connecting member, there is no need to use tools to tighten screws. As a result, it becomes possible to easily assemble the panel unit.

Effect of the Invention

[0015] According to one aspect of the present invention, it is possible to provide a panel system and a partition device that can be easily assembled.

Embodiments for Carrying out the Invention

[0017] Hereinafter, with reference to the accompanying drawings, embodiments for carrying out the panel system and the partition device according to the present invention will be described. However, the present invention is not limited only to these embodiments.

[0018] FIG. 1 is a perspective view showing the appearance of the panel unit 10 according to the present embodiment. FIG. 2 is a cross-sectional view taken along the line I-I of FIG. 1. FIG. 3 is a view showing the internal configuration of the above panel unit 10, and is a perspective view in a state where one panel material 30 is removed. FIG. 4 is a view showing the internal configuration of the above panel unit 10 from a direction different from that of FIG. 5, and is a perspective view in a state where the other panel material 30 is removed. FIG. 5 is a view of the above panel unit 10 seen from the second direction Dt in a state where one panel material 30 is removed. <Panel Unit> The panel unit 10 shown in FIG. 1 is applied to the 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.

[0019] <Support Structure> As shown in FIGS. 3 to 5, the support structure 20 is disposed between a pair of panel members 30. The support structure 20 includes a vertical frame member 21 and a horizontal frame member 22. The vertical frame member 21 extends in the vertical direction Dv. In the present embodiment, the vertical frame member 21 has, for example, a circular tube shape extending in the vertical 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 member 30.

[0020] The horizontal frame member 22 extends on both sides of the first direction Dw intersecting the vertical direction Dv with respect to the vertical frame member 21. In other words, the vertical frame member 21 supports the horizontal frame member 22 at the middle portion of the first direction Dw. In the present embodiment, the horizontal frame member 22 is disposed at the middle portion of the vertical direction Dv of the vertical frame member 21. The horizontal frame member 22 has a lower (smaller) height dimension in the vertical direction Dv than the vertical frame member 21. In the illustrated example, the dimension of the horizontal frame member 22 in the vertical direction Dv is set to about 1 / 3 of the total length of the vertical frame member 21. Thereby, the support structure 20 of the present embodiment including the vertical frame member 21 and the horizontal frame member 22 is formed in a cross shape when viewed from the second direction Dt (the direction intersecting the first direction Dw when viewed from the vertical direction Dv) intersecting the vertical direction Dv and the first direction Dw. That is, with respect to the intersection portion of the vertical frame member 21 and the horizontal frame member 22, the vertical frame member 21 protrudes on both sides in the vertical direction Dv, and the horizontal frame member 22 protrudes on both sides in the first direction Dw. In the present embodiment, the middle portion in the vertical direction Dv is a portion of the vertical frame member 21 excluding the portions protruding on both sides in the vertical direction Dv with respect to the horizontal frame member 22, and is preferably a portion excluding, for example, a 1 / 4 region located on both sides in the vertical direction Dv with respect to the total length of the vertical frame member 21. In the illustrated example, a region of about 1 / 3 located at the center of the total length of the vertical frame member 21 divided into three equal parts constitutes the middle portion in the vertical direction Dv.

[0021] The horizontal frame member 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 vertical direction Dv is smaller (lower) than the width dimension of the plate portion 23 in the first direction Dw. The flange portions 24 are respectively formed above and below the plate portion 23. The flange portions 24 respectively rise from the plate portion 23 toward the other panel member 30 side in the second direction Dt. The flange portions 24 extend in the first direction Dw. In this way, the horizontal frame member 22 is formed in a U shape when viewed from the first direction Dw.

[0022] As shown in FIGS. 3 and 4, a groove-shaped portion 22d extending in the vertical direction Dv is formed at the central portion of the horizontal frame member 22 in the first direction Dw. The middle portion of the vertical frame member 21 in the vertical direction Dv is fitted into the groove-shaped portion 22d. The vertical frame member 21 and the horizontal frame member 22 are integrally joined by appropriate joining means such as bolt joining, rivet joining, and welding at the portion of the groove-shaped portion 22d.

[0023] <Panel member> As shown in FIGS. 2 to 5, the pair of panel members 30 are arranged on both sides of the support structure 20 in the second direction Dt. The pair of panel members 30 are arranged on both sides of the support structure 20 so as to sandwich the support structure 20. The pair of panel members 30 are respectively supported by the support structure 20.

[0024] Each panel member 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 formed of a non-woven fabric or has a configuration in which a core material is covered with a tension material such as a woven fabric. Hereinafter, among the panel body 31 (panel member 30), the surface that is exposed to the outside as the panel member 30 may be referred to as the front surface, and the surface that is not exposed to the outside as the panel member 30 may be referred to as the back surface.

[0025] In the following description, when explaining each component of the panel material 30 with the same configuration among the panel materials 30, mainly one of the panel materials 30 will be used as an example for explanation. The panel 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 in a straight line shape in a longitudinal sectional view along the vertical direction Dv, and is formed in a convex arc shape in a transverse sectional view along the first direction Dw, separating from the support structure 20 as it goes from the outer end portion to the central portion in the first direction Dw. However, the surface shape of the facing portion 31f may be formed in an arc shape in both the longitudinal sectional view and the transverse sectional view, or may be formed on a flat surface orthogonal to the second direction Dt. Also, the surface shape of the facing portion 31f may be formed in a convex arc shape approaching the support structure 20 in either the longitudinal sectional view or the transverse sectional view. Note that the back surface of the facing portion 31f is formed on a flat surface orthogonal to the second direction Dt.

[0026] The panel outer edge portion 31g is formed on the outer peripheral 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 defined as the outer peripheral side, and the direction approaching the center of the panel material 30 is defined as the inner peripheral side. The panel outer edge portion 31g is formed along the four sides of the panel body 31. The panel outer edge portion 31g extends toward the other panel material 30 side 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 side in the second direction Dt as it goes from the facing portion 31f toward the outer peripheral side. As a result, the panel outer edge portions 31g of the pair of panel materials 30 project in directions 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).

[0027] The bracket 35 is arranged on the side facing the other panel material 30 with respect to the panel body 31 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 arranged on the outer peripheral portion of the panel material 30. In the present embodiment, the brackets 35 are arranged at the four corners of the panel body 31. The brackets 35 are respectively arranged on both sides of the vertical frame member 21 in the first direction Dw and on both sides of the horizontal frame member 22 in the vertical direction Dv. The upper bracket 35 with respect to the horizontal frame member 22 is placed on the horizontal frame member 22. The upper bracket 35 and the lower bracket 35 with respect to the horizontal frame member 22 sandwich the horizontal frame member 22 from the vertical direction Dv.

[0028] Each bracket 35 is separately formed in an L shape straddling the corner portion 31c at each corner portion 31c of the panel body 31. Among the brackets 35, the portion extending in the vertical direction Dv from the corner portion 31c constitutes the vertical extension portion 35a, and the portion extending in the first direction Dw from the corner portion 31c constitutes the horizontal extension portion 35b.

[0029] FIG. 6 is a perspective view showing the bracket 35 constituting the panel material 30. FIG. 7 is a perspective view showing a bracket 35 different from that in FIG. 6. As shown in FIGS. 2, 3, 6, and 7, each bracket 35 integrally has a fixed base portion 35d, an extending wall 35w, and a bracket edge portion 35g. The fixed base portion 35d constitutes the appearance of the bracket 35 as viewed from the second direction Dt, and extends in an L shape along the back surface of the panel body 31 across the vertical extension portion 35a and the horizontal extension portion 35b. The fixed base portion 35d is fixed to the back surface of the panel body 31. The extending wall 35w extends from the outer peripheral edge of the fixed base portion 35d toward the other panel material 30 side in the second direction Dt.

[0030] As shown in FIG. 2, the bracket edge portion 35g is formed at a position on the extending wall 35w that faces the panel outer edge portion 31g of the panel body 31 in the second direction Dt. The bracket edge portion 35g extends from the tip portion 35e of the extending wall 35w (the end portion on the other panel material 30 side in the second direction Dt) orthogonally to the second direction Dt toward the outer peripheral side. The brackets 35 of the pair of panel materials 30 face each other with the tip portions 35e of the extending walls 35w and the bracket edge portions 35g in contact with each other. That is, at positions that do 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 member 22), the outer peripheral portions of the pair of panel materials 30 are in contact with each other via the brackets 35.

[0031] The panel outer edge portion 31g of the panel body 31 abuts against the bracket edge portion 35g. As a result, at the portion where the bracket 35 is provided, the bracket edge portion 35g is sandwiched between the pair of panel bodies 31. In the present 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 flush with each other on the outermost peripheral surface of the panel material 30. However, only the panel outer edge portion 31g may constitute the outermost peripheral surface of the panel material 30, and the bracket edge portion 35g may be located on the inner peripheral side with respect to the panel outer edge portion 31g.

[0032] As shown in FIGS. 3 and 4, each bracket 35 is formed with a coupling portion 36 or a portion to be coupled 37. For example, a coupling portion 36 is formed in the brackets 35A disposed at two corner portions 31c facing each other in one diagonal direction among the four corners of the panel body 31 constituting the panel material 30. A portion to be coupled 37 is formed in the brackets 35B disposed at the remaining two corner portions 31c facing each other in the other diagonal direction among the four corners of the panel body 31 constituting the panel material 30.

[0033] Here, the first panel member 30A (see FIG. 3) and the second panel member 30B (see FIG. 4), which are provided as a pair of panel members 30 facing each other with the support structure 20 interposed therebetween, have the same configuration. That is, the first panel member 30A and the second panel member 30B each include a bracket 35A disposed at two corner portions 31c facing each other in one diagonal direction and a bracket 35B disposed at the remaining two corner portions 31c facing each other in the other diagonal direction. The first panel member 30A and the second panel member 30B are arranged with their orientations in the second direction Dt being different from each other. As a result, the bracket 35A disposed at two corner portions 31c facing each other in one diagonal direction of the first panel member 30A and the bracket 35B disposed at the remaining two corner portions 31c facing each other in the other diagonal direction of the second panel member 30B face each other in the second direction Dt. Also, the bracket 35B disposed at two corner portions 31c facing each other in the other diagonal direction of the first panel member 30A and the bracket 35A disposed at the remaining two corner portions 31c facing each other in one diagonal direction of the second panel member 30B face each other. In this way, the brackets 35A and 35B are provided in pairs between the corresponding corner portions 31c of the pair of first panel member 30A and second panel member 30B.

[0034] As shown in FIG. 6, in the present embodiment, the coupling portion 36 is provided at a boundary portion between the longitudinal extension portion 35a and the lateral extension portion 35b of the fixed base portion 35d in the bracket 35A. The coupling portion 36 includes a cylindrical convex portion 36t. The convex portion 36t protrudes from the fixed base portion 35d toward the other panel member 30 side in the second direction Dt. The convex portion 36t includes an elastically deformable elastic claw 36k.

[0035] As shown in FIG. 7, in the present embodiment, the portion 37 to be joined is provided at the boundary portion between the longitudinal extension portion 35a and the lateral extension portion 35b of the fixed base portion 35d in the bracket 35B. The portion 37 to be joined is formed in a cylindrical shape that protrudes from the fixed base portion 35d toward the other panel material 30 side in the second direction Dt. The portion 37 to be joined includes a recess 37s into which the convex portion 36t can be inserted. In the recess 37s, a hole 37h is formed with which the elastic claw 36k engages in a state where the convex portion 36t is inserted into the recess 37s by a predetermined dimension. By the elastic claw 36k engaging with the hole 37h, the convex portion 36t and the recess 37s are locked.

[0036] As shown in FIG. 2, at each corner portion 31c, the brackets 35A of one of the pair of panel materials 30 (the first panel material 30A and the second panel material 30B) face the brackets 35B of the other panel material 30. The coupling portion 36 (convex portion 36t) of the bracket 35A of one of the panel materials 30 fits into the portion 37 to be joined (recess 37s) of the bracket 35B of the other panel material 30. Thereby, at each corner portion 31c, the bracket 35A of one panel material 30 and the bracket 35B of the other panel material 30 are coupled. In this way, the pair of panel materials 30 are coupled via the brackets 35 at the four corners.

[0037] The bracket 35 of the first panel material 30A and the bracket 35 of the second panel material 30B among the pair of panel materials 30 are connected at a position where they do not overlap the support structure 20 when viewed from the second direction Dt. As a result, the brackets 35 provided on the outer peripheral portions of the pair of panel materials 30 are in contact with each other at a position where they do not overlap the support structure 20 when viewed from the second direction Dt. In this state, the outer panel edges 31g of the panel bodies 31 of the pair of panel materials 30 are separated from each other in the second direction Dt by the thickness of the bracket edge 35g.

[0038] Each bracket 35 is locked to the horizontal frame member 22. Specifically, as shown in FIGS. 3 and 4, the horizontal frame member 22 is formed with a bracket locking hole 22h and a locking groove 22m. The bracket locking hole 22h is formed at a predetermined position of the plate portion 23. The bracket locking hole 22h is formed so as to penetrate the plate portion 23. The locking grooves 22m are respectively formed in the upper and lower flange portions 24 of the plate portion 23. The locking groove 22m is open at the leading edge of the flange portion 24.

[0039] FIG. 8 is a cross-sectional view showing the configuration of the locking portion of the bracket 35 with respect to the horizontal frame member 22. As shown in FIGS. 6 to 8, a locking member 38 that is locked to the horizontal frame member 22 is formed on the vertical extension portion 35a of each bracket 35. The bracket 35 disposed above the horizontal frame member 22 is provided with the locking member 38 at the lower end of the vertical extension portion 35a. The bracket 35 disposed below the horizontal frame member 22 is provided with the locking member 38 at the upper end of the vertical extension portion 35a. The locking member 38 is formed in an L shape when viewed from the first direction Dw. Specifically, the locking member 38 integrally has a locking base portion 38a that protrudes and extends in the vertical direction Dv from the vertical extension portion 35a, and a locking claw 38b that protrudes from the locking base portion 38a toward the other panel member 30 side in the second direction Dt.

[0040] As shown in FIG. 8, in the bracket 35P provided on the first panel member 30A and disposed above the horizontal frame member 22, the locking claw 38b is inserted into the bracket locking hole 22h. As a result, the movement of the bracket 35P and the panel body 31 (first panel member 30A) to which the bracket 35P is fixed in the vertical direction Dv and the first direction Dw is restricted.

[0041] In the bracket 35Q provided in the second panel member 30B and disposed above the horizontal frame member 22, the locking base portion 38a is inserted into the locking groove 22m. Thereby, the movement of the bracket 35Q and the panel body 31 (panel member 30B) to which the bracket 35Q is fixed in the first direction Dw is restricted. Note that the movement of this bracket 35Q in the vertical direction Dv is restricted with respect to the bracket 35P facing in the second direction Dt by the coupling of the coupling portion 36 and the coupled portion 37. In this way, the lower ends of the brackets 35P and 35Q disposed above the horizontal frame member 22 are supported by the horizontal frame member 22 via the locking member 38.

[0042] In the bracket 35R provided in the first panel member 30A and disposed below the horizontal frame member 22, the locking claw 38b is inserted into the bracket locking hole 22h. Thereby, the movement of the bracket 35R and the panel body 31 (first panel member 30A) to which the bracket 35R is fixed in the vertical direction Dv and the first direction Dw is restricted.

[0043] In the bracket 35S provided in the second panel member 30B and disposed below the horizontal frame member 22, the locking base portion 38a is inserted into the locking groove 22m. Thereby, the movement of the bracket 35S and the panel body 31 (second panel member 30B) to which the bracket 35S is fixed in the first direction Dw is restricted. Note that the movement of this bracket 35S in the vertical direction Dv is restricted with respect to the bracket 35P facing in the second direction Dt by the coupling of the coupling portion 36 and the coupled portion 37. In this way, the lower ends of the brackets 35R and 35S disposed below the horizontal frame member 22 are supported by the horizontal frame member 22 via the locking member 38.

[0044] <Vertical connection structure of panel unit> FIG. 9 is a perspective view showing a structure for connecting the panel units 10 vertically. FIG. 10 is a perspective view showing a structure for connecting the base legs 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 to be able to connect other panel units 10 vertically. Also, as shown in FIG. 10, the panel unit 10 is configured to be able to connect the base legs 70 to the lower side. Specifically, the support structure 20 includes a lower connecting portion 25 and an upper connecting portion 26.

[0045] As shown in FIGS. 9 to 11, the upper connecting portion 26 is provided at the upper end portion of the support structure 20. The upper connecting portion 26 is provided at the upper end portion 21t of the vertical frame member 21. The upper connecting portion 26 is configured such that the lower connecting portion 25 of another panel unit 10 disposed above one panel unit 10 can be connected to the upper end portion 21t of the vertical frame member 21 in one panel unit 10. The upper connecting portion 26 includes an upper connecting member 28 and a restraining member 29.

[0046] As shown in FIG. 11, the upper connecting member 28 includes a first semi-cylindrical member 28A and a second semi-cylindrical member 28B. The first semi-cylindrical member 28A and the second semi-cylindrical member 28B are each formed in a substantially semi-cylindrical shape extending in the vertical direction Dv. The first semi-cylindrical member 28A and the second semi-cylindrical member 28B are each arranged along the outer peripheral surface of the vertical frame member 21. The first semi-cylindrical member 28A and the second semi-cylindrical member 28B are arranged to face each other in the first direction Dw with the vertical frame member 21 interposed therebetween. The first semi-cylindrical member 28A and the second semi-cylindrical member 28B configure the upper connecting member 28 to be in a substantially cylindrical shape extending in the vertical direction Dv as a whole.

[0047] As shown in FIGS. 9 and 10, a pair of flange portions 27 protruding on both sides in the second direction Dt are formed on the outer peripheral surface of the upper connecting member 28 (the first half-cylindrical member 28A and the second half-cylindrical member 28B). Each flange portion 27 extends in the vertical direction Dv. The flange portion 27 includes an upper flange portion 27A and a lower flange portion 27B that are formed with a space therebetween in the vertical direction Dv.

[0048] As shown in FIGS. 3 and 4, in order to mount the upper connecting member 28, through holes 21h are formed in the vertical frame member 21. A plurality of through holes 21h are formed at appropriate intervals in the vertical direction Dv.

[0049] As shown in FIG. 11, at the lower end portions of the upper connecting member 28 (the first half-cylindrical member 28A and the second half-cylindrical member 28B), lower end locking claws 28t that can be locked to the through holes 21h of the vertical frame member 21 are respectively formed. At the upper end portion of the first half-cylindrical member 28A, a screw insertion hole 28h that communicates with another through hole 21h is formed in a state where the lower end locking claw 28t is locked to the through hole 21h. At the upper end portion of the second half-cylindrical member 28B, a boss 28b that is inserted into another through hole 21h is formed in a state where the lower end locking claw 28t is locked to the through hole 21h. A female screw hole 28n is formed in the boss 28b.

[0050] The restraining member 29 fixes the upper connecting member 28 (the first half-cylindrical member 28A and the second half-cylindrical member 28B) to the vertical frame member 21. The restraining member 29 is, for example, a urea screw. The restraining member 29 is fastened to the female screw hole 28n formed in the boss 28b of the second half-cylindrical member 28B through the screw insertion hole 28h of the first half-cylindrical member 28A and the through hole 21h of the vertical frame member 21. The upper connecting member 28 is configured such that the position of the upper connecting member 28 in the vertical 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 through which the restraining member 29 is locked or inserted.

[0051] As shown in FIGS. 3 and 4, in each panel unit 10, a lower opening 30L and an upper opening 30K are formed between a pair of panel members 30. The lower opening 30L is formed between the lower end edges 30b (the lower sides of the panel outer edge portions 31g) of the pair of panel members 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 at the central portion in the first direction Dw and is circular when viewed from the vertical direction Dv. The circular opening 30Lc is formed at a position where the lower connecting portion 25 faces downward. The slit-shaped opening 30Ls extends from the circular opening 30Lc to both sides in the first direction Dw. The upper opening 30K is formed between the upper end edges 30t (the upper sides of the panel outer edge portions 31g) of the pair of panel members 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 at the central portion in the first direction Dw and is circular when viewed from the vertical direction Dv. The circular opening 30Kc is formed at a position where the upper connecting portion 26 faces upward. The slit-shaped opening 30Ks extends from the circular opening 30Lc to both sides in the first direction Dw.

[0052] As shown in FIGS. 9 to 11, the upper connecting member 28 is configured such that the position in the vertical direction Dv with respect to the vertical frame member 21 can be changed between a storage position P1 and a protruding position P2. As shown in FIG. 9, in the storage position P1, the upper connecting member 28 is located between the upper end edge 30t and the lower end edge 30b of the panel member 30 and is stored between the pair of panel members 30. In the storage position P1, the upper connecting member 28 is disposed below the upper end edge 30t of the panel member 30 and above the horizontal frame member 22.

[0053] As shown in FIGS. 10 and 11, at the protruding position P2, the upper connecting member 28 protrudes upward from the upper end edge 30t of the panel material 30 through the circular opening 30Kc of the upper opening 30K. At the protruding position P2, the lower locking claws 28t of the first semi-cylindrical member 28A and the second semi-cylindrical member 28B are locked to the through holes 21h located at the upper end of the vertical frame member 21. At the protruding position P2, the lower flange portion 27B of the upper connecting member 28 is disposed below the upper end edges 30t of the pair of panel materials 30. At the protruding position P2, the upper part of the upper connecting member 28 protruding upward from the circular opening 30Kc of the upper opening 30K is inserted downward into the circular opening 30Lc of the lower opening 30L of the other panel unit 10 on the upper side. At the protruding position P2, the upper flange portion 27A of the upper connecting member 28 is disposed above the lower end edges 30b of the pair of panel materials 30. Therefore, at the protruding position P2, among the upper connecting members 28, the lower part is sandwiched by the pair of panel materials 30 constituting the lower panel unit 10, and the upper part is sandwiched by the pair of panel materials 30 constituting the upper panel unit 10. In this state, the panel outer edge portion 31g located at the upper end edge 30t of the lower panel unit 10 and the panel outer edge portion 31g located at the lower end edge 30b of the upper panel unit 10 enter between the upper flange portion 27A and the lower flange portion 27B.

[0054] 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 to be insertable into the upper connecting portion 26 (see FIG. 9) of another panel unit 10 disposed below the panel unit 10 or the upper end portion 72t (see FIG. 10) of the base leg 70 installed on the installation surface F. In the lower connecting portion 25, a plurality of through holes 21h are formed in the vertical frame member 21 at intervals in the vertical direction Dv below the horizontal frame member 22.

[0055] As shown in FIGS. 9 and 11, when connecting another panel unit 10 (the upper panel unit in FIGS. 9 and 11) above one panel unit 10 (the lower panel unit 10 in FIGS. 9 and 11), the lower end locking claws 28t of the first half cylinder member 28A and the second half cylinder member 28B of the upper connecting member 28 are locked to the through hole 21h at the upper end portion 21t of the vertical frame member 21 of the lower panel unit 10. Thereby, the upper connecting member 28 is disposed at a protruding position P2 that protrudes above the upper end edge 30t of the panel member 30 through the upper opening 30K. In this state, the lower connecting portion 25 (the lower end portion 21b of the vertical frame member 21) of the panel unit 10 located above is inserted between the first half cylinder member 28A and the second half cylinder member 28B of the upper connecting member 28 disposed at the protruding position P2. Further, a urethane nut as a restraining member 29 is fastened to the upper connecting member 28 and the lower connecting portion 25 of another panel unit 10 located above. Thereby, another panel unit 10 is connected above one panel unit 10. At this time, when viewed from the upper panel unit 10, the upper connecting portion 26 of another panel unit 10 disposed below the panel unit 10 is connected to the lower connecting portion 25 of the upper panel unit 10.

[0056] Also, as shown in FIG. 10, when connecting the base leg 70 installed on the installation surface F below the panel unit 10, the lower connecting portion 25 of the panel unit 10 is inserted into the base leg connecting member 74 provided at the upper end portion 72t of the base leg 70. The base leg 70 has a base plate 71 disposed along the installation surface F and a base column 72 extending upward from the base plate 71. The base column 72 is provided with a base leg connecting member 74. A through hole (not shown) is formed in the base column 72. The base leg connecting member 74 is formed with a screw insertion hole through which a fastening member 75 such as a urethane nut is inserted and a female screw hole (not shown). The base leg connecting member 74 is cylindrical and extends in the vertical direction Dv, and the lower connecting portion 25 of the panel unit 10 is inserted inside thereof.

[0057] The lower connecting part 25 of the panel unit 10, the connecting member 74 for the base leg, and the base support column 72 are connected by fastening a fastening member 75 to the female screw hole of the connecting member 74 for the base leg through the screw insertion hole of the connecting member 74 for the base leg, the through hole 21h of the lower connecting part 25, and the through hole of the base support column 72.

[0058] <Connection of the panel unit in the first direction> FIG. 12 is a diagram showing a configuration for connecting the panel units 10 in the first direction Dw. FIG. 13 is a perspective view of the surface 41f side of the connecting member 40 used for connecting the panel units 10. FIG. 14 is a perspective view of the side opposite to the surface 41f of the connecting member 40. FIG. 15 is a view of the connecting member 40 as seen from the second direction Dt (plate thickness direction). FIG. 16 is a view of the connecting member 40 as seen from a direction intersecting the second direction Dt. As shown in FIG. 11, the panel unit 10 as described above is configured to be able to connect to another panel unit 10 adjacent in the first direction Dw. The panel unit 10 is connected to another panel unit 10 adjacent in the first direction Dw via a connecting member 40. In other words, in the panel units 10 adjacent in the first direction Dw, the end of the horizontal frame member 22 of the first panel unit (first panel) 10P on one side in the first direction Dw and the 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 a connecting member 40. Thereby, the first panel edge 10f of the first panel unit 10P (the edge on the side of the second panel unit 10Q in the first direction Dw) and the second panel edge 10g of the second panel unit 10Q (the edge on the side of the first panel unit 10P in the first direction Dw) are connected via a connecting member 40.

[0059] As shown in FIGS. 12 to 16, the connecting member 40 is made of, for example, resin and includes a plate-shaped main body portion 41. The main body portion 41 is formed in a substantially circular shape when viewed from the plate thickness direction (the second direction Dt in a state where the connecting member 40 is arranged along the plate portion 23 of the horizontal frame member 22). When connecting the first panel unit 10P and the second panel unit 10Q by the connecting member 40, the connecting member 40 abuts a member surface 41f facing one side in the second direction Dt of the main body portion 41 against a flat surface portion 23f (see FIG. 12) of the plate portion 23 of the first panel unit 10P and a flat surface portion 23f of the plate portion 23 of the second panel unit 10Q. The flat surface portion 23f faces the direction in which the flange portion 24 protrudes in the second direction Dt and is a surface intersecting 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.

[0060] 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 semi-circular arc 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 semi-circular arc 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 in a state of 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 intervals in a direction along the member surface 41f. Thereby, the second mounting plate portion 43 is arranged separated from the first mounting plate portion 42.

[0061] 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 continuously formed between the first mounting plate portion 42 and the second mounting plate portion 43 in the direction in which the linear edges 42a and 43a extend. The connecting portion 44 connects the first mounting plate portion 42 and the second mounting plate portion 43. The connecting portion 44 is configured to be elastically deformable with 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. Thereby, the connecting portion 44 connects the first mounting plate portion 42 and the second mounting plate portion 43 so as to be relatively rotatable about the rotation axis 44c along which the connecting portion 44 extends and is continuous between the first mounting plate portion 42 and the second mounting plate portion 43.

[0062] As will be described in detail later, the connecting member 40 engages with and disengages from the first panel unit 10P and the second panel unit 10Q by rotating in the circumferential direction Dc about the rotation center 40c located at the center of the main body portion 41.

[0063] The connecting member 40 includes a first locking portion 45, a second locking portion 46, an outer peripheral extending 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. The first locking portion 45 is formed, for example, in a plurality of concentric circles centered on the rotation center 40c with intervals in the circumferential direction Dc. In the present embodiment, four sets of the first locking portions 45 are formed at equal intervals in the circumferential direction Dc. Two sets of the first locking portions 45 are formed on each of the first mounting plate portion 42 and the second mounting plate portion 43.

[0064] Each first locking portion 45 has a locking piece 45s. The locking piece 45s extends from the main body portion 41 toward one side in the circumferential direction Dc and extends in the second direction Dt. In the present embodiment, the locking piece 45s 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 in the first side Dc1 (clockwise direction in FIGS. 12 and 15) of the circumferential direction Dc, and an inclined portion 45c extending obliquely from the tip of the first arm portion 45b in a direction away from the member surface 41f in the second direction Dt, and integrally has them. The first arm portion 45b and the member surface 41f of the main body portion 41 are spaced apart by a distance substantially equal to the plate thickness of the plate portion 23 in the second direction Dt. The first arm portion 45b is formed to be elastically deformable in the second direction Dt about the standing portion 45a.

[0065] The second locking portion 46 is formed radially inward with respect to the plurality of first locking portions 45 about the rotation center 40c. The second locking portion 46 is formed, for example, in two sets at intervals in the circumferential direction Dc. The second locking portion 46 is 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 cantilevered from the central portion of the main body portion 41 radially outward and a locking protrusion 46b formed at the tip 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.

[0066] As shown in FIGS. 13 and 15, the outer peripheral extension portion 47 is formed on the outer peripheral portion of the main body portion 41. The outer peripheral extension portion 47 is formed, for example, in four sets at intervals in the circumferential direction Dc. The outer peripheral extension portion 47 is formed in two sets on each of the first mounting plate portion 42 and the second mounting plate portion 43. Each outer peripheral extension portion 47 extends from the outer peripheral edge portion 41s of the main body portion 41 in the tangential direction of the outer peripheral edge portion 41s as viewed from the second direction Dt. As shown in FIGS. 14 and 16, the holding projections 48 are formed on the surface 41g of the main body 41 opposite to the member surface 41f. The holding projections 48 are formed in a pair at intervals in the circumferential direction Dc, for example, at the central portion of the main body 41. The holding projections 48 are formed one by one on each of the first mounting plate portion 42 and the second mounting plate portion 43. The holding projections 48 project from the tip of the second arm portion 46a in the second direction Dt to the side opposite to the member surface 41f side. By gripping the holding projections 48, an operator can easily hold the connecting member 40 and perform a pivoting operation around the rotation center 40c of the connecting member 40. Further, by pulling the pair of holding projections 48 from the side opposite to the member surface 41f, the second arm portion 46a can be elastically deformed, and the locking projection 46b protruding from the member surface 41f can be displaced to the surface 41g side on the opposite side.

[0067] As shown in FIG. 5, the support structure 20 of each panel unit 10 is formed with connecting member locking portions 50A and 50B to which the connecting member 40 can be locked. The connecting member locking portions 50A and 50B are formed at both ends of the plate portion 23 in the first direction Dw. As shown in FIG. 12, when connecting the first panel unit 10P and the second panel unit 10Q, the connecting member 40 straddles 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 among the panel units 10 adjacent in the first direction Dw.

[0068] As shown in FIG. 5, the connecting member locking portion 50A includes two first locked portions 51A and 51B and two second locked portions 52A and 52B. Two sets of the first locking portions 45 adjacent in the circumferential direction Dc among the four sets of the first locking portions 45 of the connecting member 40 are locked to the two first locked portions 51A and 51B. The two first locked portions 51A and 51B are each a long hole (hole) that penetrates the plate portion 23 in the second direction Dt (plate thickness direction) and extends in an arc shape with a curvature radius equal to the dimension between the rotation center 40c and the first locking portion 45. One of the first locked portions 51A opens at the side edge of the horizontal frame member 22. The two second locked parts 52A and 52B are formed inside the first locked parts 51A and 51B. One of the second locked parts 52A is a round hole 52h that penetrates the plate part 23 in the second direction Dt. The other second locked part 52B is a locking hole 52g formed by an oblong hole having the first direction Dw as the major axis.

[0069] The connecting member locking part 50B includes two first locked parts 51C and 51D, and two second locked parts 52C and 52D. Of the four sets of first locking parts 45 of the connecting member 40, the remaining two sets of first locking parts 45 (the first locking parts 45 other than the first locking parts 45 locked to the first locked parts 51A and 51B) are locked to the two first locked parts 51C and 51D. The two first locked parts 51C and 51D are oblong holes (holes) that penetrate the plate part 23 in the second direction Dt (the plate thickness direction) and extend in an arc shape with a curvature radius equal to the dimension between the rotation center 40c and the first locking part 45. One of the first locked parts 51C opens at the side edge of the horizontal frame member 22. The two second locked parts 52C and 52D are formed inside the first locked parts 51C and 51D. One of the second locked parts 52C is a round hole 52h that penetrates the plate part 23 in the second direction Dt. The other second locked part 52D is a locking hole 52g formed by an oblong hole having the first direction Dw as the major axis.

[0070] As shown in FIG. 12, the connecting member 40 locks the four sets of first locking parts 45 to the first locked parts 51A and 51B of the first panel unit 10P and the first locked parts 51C and 51D of the second panel unit 10Q, respectively. For this, the four sets of first locking parts 45 of the connecting member 40 are inserted along the second direction Dt inside the first locked parts 51A to 51D, and the member surface 41f of the connecting member 40 is brought into contact with the flat part 23f. At this time, the second locking part 46 is pushed into the second direction Dt when the locking protrusion 46b abuts against the flat part 23f of the plate part 23.

[0071] FIG. 17 is a diagram showing a locked state Pk in which each first locking part 45 of the connecting member 40 is locked to the first locked parts 51A to 51D. In this state, as shown in Fig. 17, when the connecting member 40 is rotated with respect to the plate portion 23 toward the first side Dc1 in the circumferential direction Dc, a portion 23k of the plate portion 23 that is located on the first side Dc1 in the circumferential direction Dc with respect to the first engaged portions 51A to 51D is inserted between the first arm portions 45b of each first locking portion 45 and the member surface 41f. When the connecting member 40 is further rotated and the standing portions 45a of each first locking portion 45 abut against the ends 51e on the first side Dc1 in the circumferential direction Dc of the first engaged portions 51A to 51D, each first locking portion 45 is in a locked state Pk locked to the first engaged portions 51A to 51D. Thereby, the rotation of the connecting member 40 toward the first side Dc1 in the circumferential direction Dc with respect to the plate portion 23 is restricted. At this time, the outer surfaces 47s of two of the outer peripheral extending portions 47 of the outer peripheral extending portion 47 abut against the flange portion 24 of the horizontal frame member 22. Also by this, the rotation of the connecting member 40 toward the first side Dc1 in the circumferential direction Dc with respect to the plate portion 23 is restricted.

[0072] When the connecting member 40 is rotated in the circumferential direction Dc, the locking protrusions 46b of the second locking portions 46 are in contact with the member surface 41f. When the standing portions 45a of each first locking portion 45 abut against the ends 51e on the first side Dc1 in the circumferential direction Dc of the first engaged portions 51A to 51D, the locking protrusions 46b of each second locking portion 46 face the second engaged portions 52A and 52C in the second direction Dt. Thereby, due to the second locking portion 46 being restored and deformed, the locking protrusion 46b fits into the second engaged portions 52A and 52C, or the second engaged portions 52B and 52D. In this way, with each first locking portion 45 locked to the first engaged portions 51A to 51D, each second locking portion 46 is locked to each second engaged portion 52, thereby restricting the rotation of the connecting member 40 in the circumferential direction Dc. In this way, the connecting member 40 is connected to the plate portion 23 of the support structure 20 between the pair of panel members 30 with respect to each of the first panel unit 10P and the second panel unit 10Q.

[0073] Further, in the locked state Pk shown in FIG. 17, when the pair of holding protrusions 48 are pulled from the side opposite to the member surface 41f to displace the locking protrusion 46b protruding from the member surface 41f toward the opposite surface 41g side, the locking between each second locking portion 46 and each second locked portion 52 is released.

[0074] FIG. 18 is a view showing a detached state Pr in which the engagement states between each first locking portion 45 of the connecting member 40 and the first locked portions 51A to 51D are released. In this state, as shown in FIG. 18, if the connecting member 40 is rotated relative to the plate portion 23 in the second side Dc2 in the circumferential direction Dc (counterclockwise direction in FIG. 18), the engagement states between each first locking portion 45 and the first locked portions 51A to 51D, and the engagement states between each second locking portion 46 and the second locked portions 52A and 52C are released, and the state transitions to the detached state Pr.

[0075] In this way, the connecting member 40 is configured to be shiftable between the locked state Pk and the detached state Pr by being rotated around the rotation center 40c. The connecting member 40 is brought into the locked state Pk in which each first locking portion 45 is locked to the first locked portions 51A to 51D by rotating the connecting member 40 to the first side Dc1 around the rotation center 40c. The connecting member 40 is brought into the detached state Pr in which each first locking portion 45 is detached from the first locked portions 51A to 51D by rotating the connecting member 40 to the second side Dc2 around the rotation center 40c from the locked state Pk.

[0076] Further, the connecting member 40 is configured to be able to change the attachment state of the connecting member 40 to the first panel unit 10P and the second panel unit 10Q. The connecting member 40 is configured to be able to change the attachment state of the connecting member 40 between the following first form S1 (see FIG. 19) and the second form S2 (see FIGS. 12 and 17) by changing the orientation of the connecting member 40 with respect to the first panel unit 10P and the second panel unit 10Q.

[0077] FIG. 19 is a view 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 form 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 (vertical direction Dv) in which the first panel edge 10f and the second panel edge 10g extend, intersecting 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 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.

[0078] FIG. 20 is a plan view seen from the vertical direction Dv of a state in which the first panel unit 10P and the second panel unit 10Q, to which the connecting member 40 is attached in the first form S1, are relatively rotated about the rotation axis 44c of the connecting portion 44. As shown in FIG. 20, in the first form S1, the first panel unit 10P and the second panel unit 10Q can be relatively rotated 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. Thereby, the angle θ formed by the first panel unit 10P and the second panel unit 10Q can be arbitrarily adjusted. In the present embodiment, the angle θ formed by the first panel unit 10P and the second panel unit 10Q refers to an angle formed between the first mounting plate portion 42 and the second mounting plate portion 43 with the connecting portion 44 interposed therebetween.

[0079] As shown in FIG. 19, in the first embodiment S1, in the locked state Pk, the locking projection 46b fits into the second locked portions 52B and 52D each formed by a locking hole 52g (elongated hole). Thus, the locking projection 46b locks the first panel unit 10P and the second panel unit 10Q to the second locked portions 52B and 52D in a state where they are relatively displaceable 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 configured to be changeable. In the first embodiment S1, when the first panel unit 10P and the second panel unit 10Q are relatively rotated 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, and the angle θ formed by 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.

[0080] As shown in FIG. 17, in the second embodiment S2, the connecting portion 44 extends and is arranged in a direction different from that in the first embodiment S1. In the present embodiment, the connecting portion 44 (axial direction of the rotation axis 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. Thus, 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 embodiment S2, both the first mounting plate portion 42 and the second mounting plate portion 43 extend across the first panel unit 10P and the second panel unit 10Q. In the second embodiment 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 rotation axis 44c (first direction Dw in the second embodiment S2) is supported by the first panel unit 10P. Further, in the second embodiment S2, in the locked state Pk, the other end portion 42t, 43t of each of the first mounting plate portion 42 and the second mounting plate portion 43 in the axial direction of the rotation axis 44c (first direction Dw in the second embodiment S2) is supported by the second panel unit 10Q.

[0081] 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 member 40 is attached in the second form S2, are arranged linearly when viewed from the vertical direction Dv. In the second form S2, the first mounting plate portion 42 and the second mounting plate portion 43 are arranged so as to straddle 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 along both the first mounting plate portion 42 and the second mounting plate portion 43, and are arranged linearly (the angle θ is 180°) along the first direction Dw in a plan view from the vertical direction Dv.

[0082] As shown in FIG. 17, in the second form S2, in the locked state Pk, the locking projection 46b fits into the second locked portions 52A and 52C each formed of a round hole 52h. As a result, the locking projection 46b is made incapable of relative displacement in the arrangement direction (the first direction Dw) with respect to the second locked portions 52A and 52C. Therefore, the connecting member 40 is firmly connected to the first panel unit 10P and the second panel unit 10Q, and the state in which the first panel unit 10P and the second panel unit 10Q are arranged linearly along the first direction Dw in a plan view from the vertical direction Dv is firmly maintained.

[0083] 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 closing member 80 that can close the upper opening 30K. As shown in FIGS. 22 and 23, the closing member 80 integrally has a closing portion 81 and a boss portion 82. The closing portion 81 integrally has a first closing portion 81a that closes the circular opening 30Kc of the upper opening 30K, and a second closing portion 81b that extends from the first closing portion 81a to both sides in the first direction Dw and closes the slit-shaped opening 30Ks of the upper opening 30K. The boss portion 82 is inserted into the upper opening 30K when the closing member 80 is attached to the upper opening 30K.

[0084] As shown in FIG. 5, the above-described connecting member 40 and the closing member 80 can be accommodated in the panel unit 10 when not in use. The connecting member 40 and the 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 includes a connecting member holding portion 91 and a closing member holding portion 92 in a portion covered with the panel material 30 (a portion overlapping 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 member 22. The connecting member holding portion 91 and the closing member holding portion 92 are respectively formed on both sides in the first direction Dw with the vertical frame member 21 interposed therebetween.

[0085] The connecting member holding portion 91 has a first holding hole 91a into which the first locking portion 45 of the connecting member 40 can be locked, and a second holding hole 91b into which the second locking portion 46 can be locked. The connecting member holding portion 91 can lock the connecting member 40 to the first holding hole 91a and the second holding hole 91b by rotating the connecting member 40 to the first side Dc1 (see FIG. 15) in the circumferential direction Dc in the same manner as when the connecting member 40 is attached to the connecting member locking portions 50A and 50B. Further, 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 holding hole 91a and the second holding hole 91b by rotating to the second side Dc2 (see FIG. 15) in the circumferential direction Dc.

[0086] The blocking member holding portion 92 is formed at the center of the connecting member holding portion 91. The blocking member 80 in the non-use state is detachably attached by fitting the boss portion 82 of the blocking member 80 into the blocking member holding portion 92.

[0087] <Partition device> By using one or a plurality of the panel units 10 as described above, partition devices in various forms can be configured. FIG. 24 is a diagram showing a partition device 1 configured using the panel unit 10. As shown in FIG. 24, the partition device 1 is installed on an installation surface F facing upward and is used to partition the 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 them in a plurality of rows in the first direction Dw at each stage in the vertical direction Dv. In the present embodiment, a total of six panel units 10, two rows in the first direction Dw and three stages vertically, are connected.

[0088] In each row in the first direction Dw, the partition device 1 is provided with, for example, three panel units 10 connected in the vertical direction Dv on the base legs 70 installed on the installation surface F. The panel units 10 positioned vertically with respect to each other are connected by the lower connecting portion 25 and the upper connecting portion 26 as described above. Here, the number of panel units 10 stacked vertically is not limited to three and can be increased or decreased as appropriate.

[0089] In each stage in the vertical direction Dv, a first panel unit 10P arranged in a row on one side in the first direction Dw and a second panel unit 10Q arranged in a row on the other side in the first direction Dw are each connected by the connecting members 40 between the horizontal frame members 22. At this time, as shown in FIG. 21, if the first panel unit 10P and the second panel unit 10Q are arranged linearly in a plan view seen from the vertical direction Dv, the connecting member 40 is attached to the first panel unit 10P and the second panel unit 10Q with the attachment state being the second form S2 (see FIG. 19) as shown in FIG. 20. Further, if the first panel unit 10P and the second panel unit 10Q are arranged such that the angle θ formed by the first panel unit 10P and the second panel unit 10Q is bent to 180° or less in a plan view seen 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 attachment state being the first form S1 (see FIG. 17).

[0090] To assemble the partition device 1 as described above, in each panel unit 10, with the panel material 30 removed, connection is performed using the connecting members 40 between the panel units 10 adjacent to each other in the first direction Dw, and connection is performed using the lower connecting portion 25 and the upper connecting portion 26 between the upper and lower panel units 10. Thereafter, the pair of panel materials 30 are connected by coupling the brackets 35. At this time, the connection between the panel units 10 adjacent to each other in the first direction Dw is executed by rotating the connecting member 40. Also, the connection using the lower connecting portion 25 and the upper connecting portion 26 between the upper and lower panel units 10 is performed by locking the upper connecting portion 26 to the vertical frame member 21 and tightening the restraining member 29 using a urea nut. Further, the pair of panel materials 30 are connected by coupling the brackets 35. Therefore, the assembly of each panel unit 10 and the connection work between the panel units 10 can be easily performed manually without tools.

[0091] Also, when removing the panel unit 10 or changing the combination of the panel units 10, the operations reverse to the above-described assembly method are performed. That is, first, for the panel unit 10 to be removed (target panel unit 10) and the panel unit 10 connected to the target panel unit 10 (connected panel unit 10), the connection between the pair of panel members 30 via the bracket 35 is released to expose the support structure 20. Next, between the support structures 20 of the target panel unit 10 and the connected panel unit 10, the connection by the connecting member 40 or the connection by the upper connecting portion 26 (lower connecting portion 25) is released. Thereby, the support structure 20 of the target panel unit 10 can be removed from the support structure 20 of the connected panel unit 10.

[0092] Thus, in the partition device 1 of the present embodiment, the first panel unit 10P and the second panel unit 10Q each have a flat surface portion 23f intersecting the thickness direction (second direction Dt) of the first panel unit 10P and the second panel unit 10Q. The connecting member 40 has a main body portion 41 having a member surface 41f that abuts against the flat surface portion 23f. First engaged portions 51A to 51D are formed on the main body portion 41. By rotating the connecting member 40 around a rotation center 40c extending in a direction (second direction Dt) intersecting the member surface 41f on the flat surface portion 23f to the first side Dc1, a first engaging portion 45 that can be engaged with the first engaged portions 51A to 51D is formed.

[0093] According to such a configuration, when the connecting member 40 is rotated to the first side Dc1 around the rotation center 40c with the member surface 41f of the connecting member 40 in contact with the flat portions 23f of the first panel unit 10P and the second panel unit 10Q, the first locking portion 45 is locked to the first locked portions 51A to 51D. In this way, the connecting member 40 is connected to the first panel unit 10P and the second panel unit 10Q, and the first panel unit 10P and the second panel unit 10Q are connected by the connecting member 40. Therefore, when connecting the first panel unit 10P and the second panel unit 10Q by the connecting member 40, it is not necessary to use a tool to tighten a screw. As a result, the assembly of the partition device 1 can be easily performed.

[0094] In the present embodiment, the connecting member 40 is configured to be shiftable between a locked state Pk in which the first locking portion 45 is locked to the first locked portions 51A to 51D by rotating the connecting member 40 to the first side Dc1 around the rotation center 40c, and a released state Pr in which the first locking portion 45 is detached from the first locked portions 51A to 51D by rotating the connecting member 40 to the second side Dc2 around the rotation center 40c from the locked state Pk. According to such a configuration, when the connecting member 40 is rotated to the first side Dc1 around the rotation center 40c, the first locking portion 45 is locked to the first locked portions 51A to 51D and enters the locked state Pk. Thereby, the connecting member 40 can be connected to the flat portions 23f of the first panel unit 10P and the second panel unit 10Q. Further, when the connecting member 40 is rotated to the second side Dc2 around the rotation center 40c, the first locking portion 45 that was locked to the first locked portions 51A to 51D in the locked state Pk is detached from the first locked portions 51A to 51D. Thereby, the connecting member 40 is shifted from the locked state Pk to the released state Pr, and the connecting member 40 can be removed from the first panel unit 10P and the second panel unit 10Q. In this way, by simply switching the rotation direction of the connecting member 40, the connection of the connecting member 40 to the first panel unit 10P and the second panel unit 10Q and the removal of the connecting member 40 from the first panel unit 10P and the second panel unit 10Q can be easily performed.

[0095] In the present embodiment, when the first locking portion 45 is rotated by an angle defined around the rotation center 40c in a state where the first locking portion 45 is inserted into the first locked portions 51A to 51D, the first locking portion 45 abuts against the end portion 51e of the first side Dc1 around the rotation center 40c of the first locked portions 51A to 51D, so that the first locking portion 45 is configured to be locked to the first locked portions 51A to 51D. According to such a configuration, when the connecting member 40 is rotated by an angle defined on the first side Dc1 around the rotation center 40c, the operator can easily and surely recognize that the first locking portion 45 abuts against the end portion 51e of the first side Dc1 around the rotation center 40c of the first locked portions 51A to 51D, and thus the first locking portion 45 is locked to the first locked portions 51A to 51D and has shifted to the locked state Pk.

[0096] In the present embodiment, the first locked portions 51A to 51D are holes formed in the flat portion 23f, and the first locking portion 45 is configured to include a locking piece 45s that extends from the main body portion 41 in the direction around the rotation center 40c and in the plate thickness direction of the main body portion 41. According to such a configuration, after inserting the locking piece 45s of the first locking portion 45 into the holes as the first locked portions 51A to 51D from the plate thickness direction, when the connecting member 40 is rotated to the first side Dc1 around the rotation center 40c, the flat portion 23f enters between the locking piece 45s and the main body portion 41, and the first locking portion 45 is locked to the first locked portions 51A to 51D. In this way, with the locking piece 45s having a simple configuration, it becomes possible to connect the connecting member 40 to the first panel unit 10P and the second panel unit 10Q.

[0097] In this embodiment, second engaged portions 52A to 52D are formed on the main body portion 41, and the connecting member 40 is rotated around the rotation center 40c extending in a direction intersecting the member surface 41f on the flat surface portion 23f, and a second engaging portion 46 that is engaged with the second engaged portions 52A to 52D is formed in a state where the first engaging portion 45 is engaged with the first engaged portions 51A to 51D. According to such a configuration, when the connecting member 40 is rotated around the rotation center 40c and the second engaging portion 46 is engaged with the second engaged portions 52A to 52D in a state where the first engaging portion 45 is engaged with the first engaged portions 51A to 51D, the rotation of the connecting member 40 around the rotation center 40c is restricted. As a result, the first engaging portion 45 is restricted to a state of being engaged with the first engaged portions 51A to 51D, and it is possible to prevent the connecting member 40 from accidentally coming off from the first panel unit 10P and the second panel unit 10Q.

[0098] In this embodiment, the connecting member 40 is configured to be connected to the flat surface portion 23f of the support structure 20 between the pair of panel members 30 for each of the first panel unit 10P and the second panel unit 10Q. According to such a configuration, the connecting member 40 is connected to the support structure 20 between the pair of panel members 30 with respect to the flat surface portion 23f of each of the first panel unit 10P and the second panel unit 10Q, so that the attachment portions of the connecting member 40 to each of the first panel unit 10P and the second panel unit 10Q are prevented from being exposed to the outside. Further, 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.

[0099] In this embodiment, the connecting member 40 has a first form S1 in which the connecting portion 44 is disposed between the first panel unit 10P and the second panel unit 10Q, the first mounting plate portion 42 is supported by the first panel unit 10P, and the second mounting plate portion 43 is supported by the second panel unit 10Q, and a second form S2 in which the connecting portion 44 is disposed across the first panel unit 10P and the second panel unit 10Q along the first direction Dw, and both the first mounting plate portion 42 and the second mounting plate portion 43 are supported across the first panel unit 10P and the second panel unit 10Q. The mounting state of the connecting member 40 with respect to the first panel unit 10P and the second panel unit 10Q can be changed. According to such a configuration, the first form S1 of the connecting member 40 is realized by disposing the connecting portion 44 between the first panel unit 10P and the second panel unit 10Q, supporting one first mounting plate portion 42 by the first panel unit 10P, and supporting the other second mounting plate portion 43 by the second panel unit 10Q. In the first form S1, the first panel unit 10P and the second panel unit 10Q can rotate relative to each other 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. Thereby, the angle formed by the first panel unit 10P and the second panel unit 10Q can be arbitrarily adjusted. Further, in the second form S2, the first mounting plate portion 42 and the second mounting plate portion 43 are disposed so as to straddle the first panel unit 10P and the second panel unit 10Q, respectively, and are supported by the first panel unit 10P and the second panel unit 10Q, respectively. As a result, the first panel unit 10P and the second panel unit 10Q are fixed in a state along at least one of the first mounting plate portion 42 and the second mounting plate portion 43. The first panel unit 10P and the second panel unit 10Q are constrained to be linearly arranged. Therefore, there is no need to separately use different connecting members 40 for the first form S1 and the second form S2. By simply changing the orientation of the same connecting member 40, both the first form S1 and the second form S2 can be realized. As a result, the angle θ formed by the first panel unit 10P and the second panel unit 10Q can be easily changed, and when the first panel unit 10P and the second panel unit 10Q are arranged linearly, it is possible to reliably maintain the state where the first panel unit 10P and the second panel unit 10Q are linearly arranged.

[0100] In the partition device 1 of the present embodiment, the first panel unit 10P and the second panel unit 10Q are respectively installed on the installation surface F facing upward, and the first panel unit 10P and the second panel unit 10Q are arranged side by side in the direction along the installation surface F, whereby the indoor space formed above the installation surface F can be partitioned. In such a partition device 1, with the member surface 41f of the connecting member 40 in contact with the flat portions 23f of the first panel unit 10P and the second panel unit 10Q, the connecting member 40 is rotated to the first side Dc1 around the rotation center 40c, so that the connecting member 40 is connected to the first panel unit 10P and the second panel unit 10Q, and the first panel unit 10P and the second panel unit 10Q are connected by the connecting member 40. Therefore, when connecting the first panel unit 10P and the second panel unit 10Q by the connecting member 40, there is no need to use a tool to tighten a screw. As a result, the assembly of the partition device 1 can be easily performed.

[0101] (Other Embodiments) As described above, the preferred embodiments of the present invention have been described, but the present invention is not limited to these embodiments. Additions, omissions, substitutions, and other changes to 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 appended claims. For example, in the above-described embodiment, the connecting member 40 is connected in a state of being in contact with the flat surface portion 23f formed on the horizontal frame member 22 of the first panel unit 10P and the second panel unit 10Q, but the present invention is not limited to this.

[0102] Further, in the above-described embodiment, an example is shown in which the first panel unit 10P and the second panel unit 10Q constituting the partition device 1 are connected by the connecting member 40, but the present invention is not limited to this. A configuration in which the first panel unit 10P and the second panel unit 10Q are connected by the connecting members 40 and 60 may be a panel system for various uses configured by connecting a plurality of panels other than the partition device 1.

[0103] Also, the arrangement direction of the first panel unit 10P and the second panel unit 10Q connected by the connecting member 40 is not limited to the first direction Dw, and may be other directions such as the vertical direction Dv.

[0104] Further, in the above-described embodiment, the connecting member 40 is arranged only in the middle portion in the vertical direction Dv of the first panel unit 10P and the second panel unit 10Q, but the connecting member 40 may be provided at a plurality of locations in the vertical direction Dv. Further, the connecting members 40 and 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 the present invention is not limited to this. The connecting members 40 and 60 may be configured by combining separate parts for the first mounting plate portion 42, the second mounting plate portion 43, and the connecting portion 44, or other materials such as metal may be adopted.
