DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhibition wall suitably used in museums and the like.

[0002]

2. Description of the Related Art When paintings, books, etc. are displayed in museums and other museums, not only architectural walls but also partition walls that partition the exhibition space are often used as exhibition surfaces.

Conventionally, this type of wall body is generally constructed by attaching panels to both sides of a frame assembled by on-site construction, and is dismantled when the event is over.

[0004]

However, disassembling and assembling such a wall body for each pattern change requires a great deal of time and labor, and manpower is insufficient as in recent years. It is a particularly big problem in an era of

[0005] In museums and the like, it is general that a storage is installed in addition to the exhibition space, and it is conceivable to store the wall of such a storage without disassembling it. However, since such a wall body is bulky, if it is stored as it is, the space for accommodating other equipment and the like will be significantly narrowed, which causes a problem.

The present invention aims to solve all such problems.

[0007]

In order to achieve the above object, the present invention takes the following measures. That is, the display wall according to the present invention includes a pair of frames, casters for movably supporting these frames, frame fixing means for invalidating the running function of the casters at a desired position, and both of these. A link mechanism that connects the frames so that they can be brought into contact with each other, an operation mechanism that operates the link mechanism to bring them into contact with and separate between a separated use position and an approaching storage position, and an outer surface side of the both frames. Ri name and and a panel that each attached, link machine
It is characterized in that the components are concentrated on the lower half portions of both frames .

In order to effectively prevent a fall when the frame is moved to the storage position, it is positioned between both panels when both frames are set in the use position, and both frames are stored at the storage position. It is better to equip the bottom with a fall-prevention bar so that both ends thereof project outwardly from the panel when they are brought close to each other.

In order to allow the fall prevention bar to project evenly to both sides with a simple structure, for example, the fall prevention bar is slidably passed through tubular brackets fixed to both frames, and the fall prevention bar is provided. A large-diameter portion is provided in the central portion of the above, which is held between the two tubular brackets at the storage position.

As a concrete mode of the link mechanism, an X having a pair of link members whose central parts are pivotally connected to each other is provided.
A link method can 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.

As a concrete mode of the operating mechanism, for example,
A nut provided at a pivot point of the link mechanism, a pair of operation link members having one end pivotally connected to each other and the other end pivotally attached to each link member of the link mechanism, and pivot points of these operation link members. An example thereof is one that includes a screw rod that is rotatably held at a knot and has a tip side screwed into the nut, and an operating portion that is provided at the base end of the screw rod.

For the convenience of movement, it is desirable that the upper ends of both frames be constructed so that they can be folded inward together with the panels.

[0013]

With such a structure, if the caster running function is stopped by the frame fixing means after the frame is separated to the use position, the entire wall body is installed on the floor. Become. Therefore, it is possible to use the outer surfaces of both panels mounted on both frames as an exhibition surface.

When this wall body is put away, after the function of the caster is restored, the link mechanism is operated by the operating mechanism to bring both frames close to the storage position. In this state, if the entire wall is pressed, the entire wall body can be moved lightly by utilizing the function of the casters, and the wall body can be carried into a storage or the like.

As described above, in the wall body of the present invention, the link mechanism is actuated by the operating mechanism to install both frames, and the frame is connected between the use position where the stability is high and the storage position where the overall volume can be reduced. Can be operated separately. That is,
The link mechanism is concentrated on the lower half of both frames.
Therefore, the center of gravity of the entire wall is lowered, improving stability.
And the space in the upper half of both frames
Can be formed. Therefore, it can be appropriately used for an exhibition and can be stored when it is not needed, without the trouble of assembling and disassembling. In addition, in the display state, it can be installed in a stable state, and it becomes possible to bring the frames close to each other to store them in a space-saving state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 to 3, the exhibition wall body has a pair of frames 1, casters 2 for movably supporting the frames 1, and a running function of the casters 2 at a desired position. A frame fixing means 3 for invalidating and a horizontal link mechanism 4 for connecting the both frames 1 so that they can be contacted and separated from each other.
And the stand-up link mechanism 5, the operating mechanism 6 for operating the stand-up link mechanism 5 to move the two frames 1 into and out of a separated use position a and an approaching storage position b, and outer surfaces of the two frames 1. And a panel 7 mounted on each side.

More specifically, each frame 1 is made of metal, and casters 2 are attached to mounting plates 12b horizontally fixed to both ends of the bottom frame member 12a. In addition,
The upper end 11 of each frame 1 and the frame main body 12 each have a frame shape, and the upper end 11 is hinged to the upper edge 12b of the frame main body 12 via a hinge 13.
Thus, the upper end portion 11 can be folded toward the inner surface 1n as shown by an imaginary line in FIG. In addition, a fall prevention bar 8 is provided between the bottom frame members 12a forming the frame bodies 12 of both frames 1.
The fall-prevention bar 8 is located between both panels 7 when both frames 1 are set to the use position a, and both end portions 8 a of the both ends are more than the panel 7 when both frames 1 are brought close to the storage position b. The size is set so that it projects outward.
As shown in FIG. 5, the fall prevention bar 8 is slidably pierced through a tubular bracket 14 fixed to both frames 1, and a large diameter portion 81 is provided in the center thereof. The large-diameter portion 81 is sandwiched between the tubular brackets 14 and centered when the two frames 1 are brought close to the storage position b as shown by an imaginary line in FIG.

The frame fixing means 3 is provided on a mounting plate 15 fixed to the bottom frame member 12a of the frame 1 as shown in FIG. 4, and a nut 31 fixed to the mounting plate 15 and this nut 31. And a threaded rod 32 screwed into the
It comprises a grounding portion 33 provided at the lower end of 2 and a lever 34 for rotating the screw rod 32. When the screw rod 32 is screwed down by operating the lever 34, the grounding portion 33 is grounded on the floor surface F and the adjacent caster 2 is lifted.

As shown in FIGS. 1 and 3, the horizontal link mechanism 4 is provided between the bottom portions of both frames 1 and between the middle portions thereof, and forms a pair of links in which the central portions are mutually pivoted. The roller 41c has an X-link structure having a member 41, and has one end 41a of each link member 41 pivotally attached to each frame 1 and the other end 41b thereof.
Is guided to a rail member 42 fixed to each frame 1. The rail member 42 has a rectangular pipe shape, and the roller 41c is rotatably accommodated in the rail member 42, and the support shaft 43 that pivotally supports the roller 41c is provided on the upper surface of the rail member 42. It is adapted to move within the provided long hole 44.

The standing link mechanism 5, as shown in FIG.
It is provided between the end portions of both frames 1 and has an X-link structure having a pair of link members 51 whose central portions are pivotally connected to each other, and one end 51a of each link member 51 is It is axially attached 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 in the shape of a square pipe, and the roller 51c is rotatably accommodated in the rail member 52.
The support shaft 53 that supports c is configured to move within the elongated hole 54 provided in the rail member 52. in this way,
The horizontal link mechanism 4 and the standing link mechanism 5 are both frames.
1 are arranged centrally on the lower half side.

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 operation link members 62 in which one end 62a is pivotally connected to each other and each other end 62b is pivotally attached to each link member 51 of the standing link mechanism 5, and these operation link members 62.
A screw rod 64 rotatably held by a member 63 provided at the pivot point of the screw rod 64, and the distal end side of which is screwed into the nut 61, and a handle-like operation portion 65 provided at the base end of the screw rod 64. I will do it.

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

Reference numeral 9 is an auxiliary bar. That is, when folding the upper end portion 11 of the auxiliary bar 9, at least one end thereof can be detached from the frame 1 and retracted to a position where it does not interfere.

In the case of such a structure, 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 screw rod 32,
When all the casters 2 are floated from the floor surface F, the entire wall body is installed on the floor F. Therefore, the outer surface 7g of each panel 7 mounted on both frames 1 can be used as an exhibition surface. In actual use, a plurality of wall bodies A shown in the drawing are arranged in the lateral direction. In that case,
If necessary, it is advisable to connect the frames 1 of the adjacent wall bodies A to each other by connecting means 10 as shown in FIG. 7, for example. The connecting means 10 pivotally mounts a connecting plate 111 having an engaging portion 111a at one end thereof on one of adjacent frames 1 in a rotatable manner, and a bolt 113 having an operating grip 112 on the other by screwing. There is. Then, the engaging portion 111a of the connecting plate 111 is engaged with the bolt 113 at a position where the wall bodies A are adjacent to each other, and the operating grip 112 is rotated to screw the bolt 113 into the connecting plate 111. Is clamped between the operation grip 112 and the frame 1. FIG. 7 shows a connecting means 10 for connecting between the bottom portions of the frame body 12 of the wall body A. The connecting means 10 is provided in the vicinity of the upper end of the frame body 12 or the upper end portion 11 of the frame 1. It is also good to set up.

When the wall A is to be put away, first, the operating grip 112 is rotated to connect the connecting plate 111 to the bolt 1.
After releasing from 13 and releasing the restraint by the auxiliary bar 9, the upper end 11 of the frame 1 is sequentially moved to the inner surface 1n.
Fold it to the side. Then, the lever 34 is operated in the opposite direction so that the grounding portion 33 is levitated from the floor surface F, and the function of the caster 2 is restored. Then, the operation portion 65 of the operation mechanism 6 is rotated to reduce the expansion angle of the link members 51 and the operation link members 62, and the both frames 1 are brought close to the storage position b. In this state, if the entire wall body is pressed, the entire wall body can be moved lightly by using the function of the casters 2, and can be carried into a storage or the like. At this time, if the upper end 11 of the frame 1 is folded, it is possible to easily pass through an opening or a passage having a relatively small height. Further, when both frames 1 are brought close to the storage position b, both end portions 8a of the overturn preventing bar 8 are projected more outward than the outer surface 7a of both panels 7.
In this case, since the large-diameter portion 81 of the fall prevention bar 8 is sandwiched and centered by the tubular brackets 14 of both frames 1, both ends 8a of the fall prevention bar 8 project evenly. If such a fall prevention bar 8 is provided, if the entire wall A is slightly inclined, the fall prevention bar 8
Comes into contact with the floor surface F, and further tilting is prevented. Therefore, even if the wall body A is moved to the storage position b and the wall body A is moved, it is difficult to fall down. Moreover, since the fall prevention bar 8 is only partially projected and can be made to sneak into the bottom portion of another wall body A, the position of the fall prevention bar 8 is sequentially shifted and overlapped. As a result, it is possible to tightly store the plurality of wall bodies A. Furthermore, the width that can be stored in this way
Even in the extended state, the horizontal link mechanism 4 and the standing link machine
Structure 5 is concentrated on the lower half side of both frames 1.
It has a lower center of gravity and is also on the frame 1
Since the space can be formed in the half part, the upper end 11 is
The height dimension can be reduced by folding to the 1n side.
Therefore, the stability of the wall body A itself can be increased. I
Therefore, the frame 1 is separated and widened as when using.
Even if the condition is not deteriorated, the possibility of falling is high and
It is possible to secure safety.

The present invention is, of course, not limited to the embodiment described above. For example, as shown in FIG.
The stay 201 is provided between the upper end portion 11 of the frame 1 and the frame body 12, and the lower end portion of the stay 201 is supported by the lock mechanism 202.
It is possible to improve safety by keeping the inside from suddenly falling. As for the lock mechanism 202 used in such a place, the lock position is set to 1 by alternately applying a compressive force and a tensile force to the stay 201.
It is preferable to use a system that moves downward step by step. Further, the bar body 203 is held by the frame body 12 so as to be able to move up and down, and the bar bar 203 is raised at a position where the upper end portion 11 of the frame 1 is vertically erected and engaged with the upper end portion 11. You may make it prevent the upper end part 11 from inclining to the inner surface side. Although the barb 203 can be held in the raised position by rotating, the locking pin and the like for this are well known and are not shown.

Further, the structure of the link mechanism and the operating mechanism is not limited to that of the illustrated embodiment. For example, as shown in FIG. 9, the upper end of each link member 51 is pivotally attached to the frame 1, The lower end may be slidably supported. With this configuration, it is possible to prevent the operating portion 65 of the operating mechanism 6 from significantly moving up and down as the frame 1 comes in and out.

[0029]

EFFECTS OF THE INVENTION Since the present invention has the above-described structure, the link mechanism is operated by the operating mechanism to install both frames, and the use position is highly stable and the storage position is capable of reducing the overall bulk. It can be moved to and from. Therefore, it can be appropriately used for an exhibition and can be stored when it is not needed, without the trouble of assembling and disassembling. That is, according to the wall body of the present invention, since it is possible to secure a necessary thickness in an exhibition state, the wall body can be installed in a stable state, and when storing the frame, the frame is made close to each other to save space. It becomes possible to make it into a state. Moreover, the link mechanism does not
Center of gravity is low due to concentration in the lower half of the ram
Therefore, stability can be increased. this
As a result, the possibility of tipping is low and
It is possible to secure safety.
