BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhibition wall suitable for use in art galleries, museums, etc.

0002

2. Description of the Related Art When exhibiting paintings, calligraphy, etc. in art galleries, museums, and other places, not only architectural walls but also partition-like walls that partition exhibition spaces are often used as exhibition surfaces.

[0003] Conventionally, this type of wall has generally been constructed by attaching panels to both sides of a frame assembled on-site, and is dismantled after the event is over.

0004

[Problem to be solved by the invention] However, it takes a lot of time and effort to disassemble and reassemble such walls every time they are redecorated, and there is a shortage of manpower these days. This is a particularly big problem in the current era.

[0005] In addition, in museums, etc., storage rooms are generally installed in areas other than the exhibition halls, and it may be possible to store the walls of such storage rooms without dismantling them. However, since such a wall body is bulky, if it is stored as is, there will be a problem in that the space for storing other equipment etc. will be significantly reduced.

The present invention aims to solve all of these problems.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention takes the following measures. That is, the exhibition wall according to the present invention includes a pair of frames, casters that movably support these frames, frame fixing means for disabling the traveling function of the casters at a desired position, and both of these. a link mechanism that connects the frames so that they can be moved toward and away from each other; an operating mechanism that operates the link mechanism to move the frames toward and away between a used position where they are separated and a storage position where they are close; It is characterized by comprising a panel attached to each.

[0008] In order to effectively prevent the frames from falling when moving them close to the storage position, when both frames are set in the use position, the frame should be located between both panels, and both frames should be placed in the storage position. If the panels are brought close to each other, it is advisable to equip the bottom with an anti-fall bar with both ends protruding outward from the panel.

[0009] In order to have the fall prevention bar protrude equally to both sides with a simple structure, for example, the fall prevention bar may be slidably penetrated through tubular brackets fixed to both frames, and the fall prevention bar A large diameter portion is provided in the center of the housing to be held between the tubular brackets at the storage position.

[0010] As a specific embodiment of the link mechanism, an X
A link method may be considered. In this case, one end of each link member is pivotally attached to each frame, and the other end is slidably supported by each frame.

[0011] Specific aspects of the operating mechanism include, for example,
A nut provided at a pivot point of the link mechanism, a pair of operating link members having one end pivoted to each other and the other end pivoted to each link member of the link mechanism, and the pivot of these operating link members. One example includes a threaded rod that is rotatably held at a node and whose distal end is screwed into the nut, and an operating section provided at the base end of the threaded rod.

[0012] In order to facilitate movement, it is desirable that the upper ends of both frames be configured so that they can be folded inward together with the panel.

[0013]

[Operation] With this kind of configuration, if the frame is moved away to the use position and the running function of the casters is stopped by the frame fixing means, the entire wall will be installed on the floor. Become. Therefore, the outer surfaces of both panels attached to both frames can be used as display surfaces.

When the wall is to be put away, after restoring the function of the casters, the operating mechanism operates the link mechanism to bring both frames close to the storage position. In this state, by pressing the entire wall, the entire wall can be easily moved using the action of the casters, and can be carried into a storage room or the like.

In this manner, the wall of the present invention connects both frames between the use position where installation stability is high and the storage position where the overall bulk can be reduced by operating the link mechanism using the operation mechanism. Can be operated separately. Therefore, it can be used for display as appropriate and stored when not needed, without requiring the effort of assembling or disassembling it. And, in the exhibition state, it can be installed in a stable state,
When storing, the frames can be moved close together to save space.

Thus, this upper end portion 11 can be folded toward the inner surface 1n, as shown by the imaginary line in FIG. Further, a fall prevention bar 8 is installed between the bottom frame members 12a of the frame bodies 12 of both frames 1. The anti-fall bar 8 is located between both panels 7 when both frames 1 are set at the use position a, and when both frames 1 are brought close to the storage position b, both ends 8a thereof are located above the panels 7. The dimensions are set so that it protrudes outward. As shown in FIG. 5, the anti-fall bar 8 is slidably passed through a tubular bracket 14 fixed to both frames 1, and has a large diameter portion 81 at its center. This large diameter portion 81 is designed to be centered between the two tubular brackets 14 when both frames 1 are brought close to the storage position b as shown by imaginary lines in FIG.

The frame fixing means 3 is provided on a mounting plate 15 fixed to the bottom frame material 12a of the frame 1, as shown in FIG. The threaded rod 32 screwed into the threaded rod 3
2, and a lever 34 for rotating the threaded rod 32. When the lever 34 is operated to screw the threaded rod 32 downward, the grounding portion 33 contacts the floor F and the adjacent caster 2 is lifted up.

As shown in FIGS. 1 and 3, the horizontal link mechanism 4 is provided between the bottoms of both frames 1 and between the middle portions, and is a pair of links whose center portions are pivoted to each other. It has an X-link structure having members 41, one end 41a of each link member 41 is pivoted to each frame 1, and a roller 41c is pivoted to the other end 41b.
is guided by a rail member 42 fixed to each frame 1. The rail member 42 is shaped like a rectangular pipe, and the roller 41c is rotatably accommodated in the rail member 42. A support shaft 43 that pivotally supports the roller 41c is attached to the upper surface of the rail member 42. It is designed to move within a long hole 44 provided.

As shown in FIG. 3, the erecting link mechanism 5 has the following structure:
It is provided between the two frames 1 near one end, and has an X-link structure comprising a pair of link members 51 whose central parts are mutually pivoted, and one end 51a of each link member 51 is It is pivoted to each frame 1, and the other end 5
A roller 51c pivotally attached to 1b is guided by a rail member 52 fixed to each frame 1. The rail member 52 is shaped like a rectangular pipe, and the roller 51c is rotatably accommodated in the rail member 52.
A support shaft 53 that pivotally supports c is adapted to move within a long hole 54 provided in the rail member 52.

As shown in FIGS. 3 and 6, the operating mechanism 6 includes a nut 61 provided at the pivot point 5s of the upright link mechanism 5.
and a pair of operating link members 62 whose one ends 62a are pivotally connected to each other and whose respective other ends 62b are pivotally connected to each link member 51 of the upright link mechanism 5, and these operating link members 62.
A threaded rod 64 is rotatably held by a member 63 provided at a pivot point of the threaded rod 64 and has its tip end screwed into the nut 61, and a handle-like operating portion 65 provided at the base end of the threaded rod 64. It will be done.

As shown in FIG. 2, the panels 7 have a horizontally long rectangular shape, and a plurality of panels 7 are attached to the outer surfaces of both frames 1 so as to be vertically adjacent to each other. Each panel 7 may be mounted using an appropriate bracket (not shown) or the like. The uppermost panel 7 is supported by the upper end 11 of the frame 1, and follows when the upper end 11 is folded inward.

Note that 9 is an auxiliary bar. That is, when folding the upper end portion 11 of the auxiliary bar 9, at least one end can be removed from the frame 1 and retracted to a position where it does not get in the way.

With such a configuration, after the frame 1 is separated to the use position a, the lever 34 of each frame fixing means 3 is operated to lower the threaded rod 32,
When all the casters 2 are lifted off the floor F, the entire wall body will be installed on the floor F. Therefore, the outer surface 7g of each panel 7 attached to both frames 1 can be used as an exhibition surface. In actual use, a plurality of wall bodies A shown in the drawings are arranged in a horizontal direction. In that case,
If necessary, it is preferable to connect the frames 1 of adjacent wall bodies A with each other using a connecting means 10 as shown in FIG. 7, for example. This connecting means 10 has a connecting plate 111 having an engaging portion 111a at its tip rotatably pivoted to one of the adjacent frames 1, and a bolt 113 having an operating grip 112 screwed to the other side. There is. Then, the engaging portion 111a of the connecting plate 111 is engaged with the bolt 113 at a position adjacent to the wall A, and the operating grip 112 is rotated to screw the bolt 113 into the connecting plate 111. is clamped and fixed between the operating grip 112 and the frame 1. FIG. 7 shows a connecting means 1 for connecting the bottom parts of the frame body 12 of the wall body A.
0, the connecting means 10 is preferably provided near the upper end of the frame body 12 or also at the upper end 11 of the frame 1.

When cleaning up this wall A, first rotate the operation grip 112 to connect the connecting plate 111 with the bolt 1.
13 and release the restraint by the auxiliary bar 9, the upper end 11 of the frame 1 is sequentially removed from the inner surface 1n.
Fold to the side. Then, by operating the lever 34 in the opposite direction, the ground contact portion 33 is raised from the floor surface F, and the function of the caster 2 is restored. Thereafter, the operating portion 65 of the operating mechanism 6 is rotated to reduce the expansion angles of the link members 51 and the operating link members 62, and both frames 1 are brought closer to the storage position b. In this state, if the entire wall is pressed, the entire wall can be easily moved using the function of the casters 2, and can be carried into a storage room or the like. At this time, if the upper end 11 of the frame 1 is folded, it is possible to easily pass through openings and passages with relatively low height dimensions. Furthermore, when both frames 1 are brought close to storage position b, both ends 8a of fall prevention bar 8 protrude outward beyond outer surfaces 7a of both panels 7. In this case, since the large diameter portion 81 of the fall prevention bar 8 is held and centered by the tubular brackets 14 of both frames 1, both ends 8a of the fall prevention bar 8 protrude evenly. However, if such a fall prevention bar 8 is provided, when the entire wall A is slightly tilted, the fall prevention bar 8 will come into contact with the floor surface F, thereby preventing further tilting. Become. Therefore, even if the wall A is moved by reducing its width to the storage position b, it will not easily fall over. Moreover,
This fall prevention bar 8 only partially protrudes, and can be sunk into the bottom of another wall A. Therefore, by sequentially shifting the positions of the fall prevention bars 8 and overlapping them, It is possible to closely house a plurality of wall bodies A.

It should be noted that the present invention is of course not limited to the embodiments described above; for example, as shown in FIG.
A stay 201 is provided between the upper end 11 of the frame 1 and the frame main body 12, and the lower end of the stay 201 is supported by a locking mechanism 202.
Safety can be increased by preventing the objects from falling all at once toward the inside. The locking mechanism 202 used in such a location is such that the stay 201 is locked at a single locking position by alternately applying compressive force and tensile force to the stay 201.
It is preferable to use a system that moves downward step by step. Further, the bolt 203 is held in the frame body 12 so as to be movable up and down, and the bolt 203 is raised and engaged with the upper end 11 at a position where the upper end 11 of the frame 1 is vertically erected. The upper end portion 11 may be prevented from falling toward the inner surface. The lock 203 can be held in the raised position by rotating it, but the locking pins and the like for this purpose are well known and are therefore not shown.

Furthermore, the configurations of the link mechanism and the operating mechanism are not limited to those of the illustrated embodiment; for example, as shown in FIG. The lower end may be slidably supported. In this way, it is possible to prevent the operating portion 65 of the operating mechanism 6 from moving up and down significantly as the frame 1 approaches and separates.

[0029]

[Effects of the Invention] Since the present invention has the above-described configuration, the link mechanism is actuated by the operation mechanism, and both frames can be installed at a use position with high stability and a storage position where the overall bulk can be reduced. It is possible to perform contact and separation operations between the two. Therefore, there is no need for assembly or disassembly.
It can be used for display as needed and stored when not needed. In other words, according to the wall body of the present invention, in the display state, the required thickness can be ensured, so it can be installed in a stable state, and when it is stored, the frames are brought close together so that it does not take up space. It is possible to make the state.
