2. Description of the Related Art In order to display an article such as a product in the above-mentioned various spaces, a display case provided with a transparent case on an exhibition stand is used so that the display is not directly touched.

Conventionally, there are two types of display cases, one that cannot be disassembled, and one that can be disassembled. The former case, which cannot be disassembled, uses a box-like structure made by gluing, nailing, or screwing the display stand and transparent case. It has a structure assembled in.

[0004] The latter disassembly has a structure in which a frame structure is made of an extruded aluminum material, an iron pipe, or the like, and a glass plate, a plastic plate, or the like is fitted and fastened with screws while being assembled.

[0005]

However, in the case of the former structure which cannot be disassembled, it is bulky when used many times at an exhibition or the like at a time, or when used many times at a mobile exhibition or the like, so that the transportation cost and the warehouse cost are increased. Storage costs are high, and as a result they are often thrown away in short cycles, leading to resource problems and garbage problems.

[0006] The latter, which can be disassembled, has a problem in that it is structurally complicated, requires time and labor to assemble and disassemble, and is difficult for a layman to work.

Therefore, an object of the present invention is to assemble and disassemble even an unskilled person, to facilitate repeated use, to reduce the weight and size during disassembly, and to reduce initial costs and running costs. It is an object of the present invention to provide a foldable display case.

[0008]

To solve the above problems BRIEF SUMMARY OF THE INVENTION, The invention according to claim 1, formed on the interpolated so fitted and rectangular tube-shaped case foldable, the lower end portion of the rectangular cylindrical-shaped case Height adjustable lower frame, a groove is provided in the periphery of the upper surface, a top plate that fits into the upper end of the rectangular tubular case, and four sheets that fit the lower end into the groove of this top plate With a transparent plate,
In a display case composed of a ceiling plate provided with a groove for fitting the transparent plate on the periphery to hold the transparent plate at the upper end, both ends in the vertical direction of each transparent plate are inclined at 45 °. For a pair of two transparent plates that are cut and opposed to each other, an angle material is fixed to the outer peripheral surfaces of both ends so that one side protrudes at a right angle to the inclined surface side, and the inclination between the opposed transparent plates is set. This adopts a configuration in which a transparent case is assembled by inserting another set of two transparent plates between the surfaces.

[0009]

[Function] If the lower end of the rectangular cylindrical case is fitted into the lower frame and the concave portion of the top plate is fitted and placed on the upper end of the rectangular cylindrical case, the assembling of the display stand is completed. By folding the rectangular cylindrical case flat, the whole becomes low in bulk. On the display stand, a pair of transparent plates are erected in opposition, and angle materials are fixed to both ends in the vertical direction of the transparent plates. When inserted between the angles facing each other, the transparent plate is cut at 45 ° at both ends in the vertical direction, so that it is easy to insert, the cut surfaces abut each other, and a transparent case with stable strength is assembled.

FIG. 1 and FIG. 2 show a display case in which a display stand 1 and a transparent case 2 are combined.
The transparent case 2 is formed by four transparent plates 6a to 6d and an upper frame 7 constituting a ceiling plate.

First, in the display stand 1, the rectangular tubular case 4 of the first example shown in FIGS. 1 to 4 has four panels 8 having the same size arranged in a tubular shape. Adjacent longitudinal side edges are connected using hinges 9 and FIG.
From the flat folded state shown by the solid line, it can be developed into a rectangular tube shape as shown by the dashed line in FIG.

As shown in FIGS. 4 (C) and 4 (D), the hinge 9 has a pair of mounting portions 10, 10 formed in a U-shaped cross section using a hard synthetic resin, for example, hard vinyl chloride.
It has a structure integrally formed with a connection portion 11 made of a soft synthetic resin, for example, soft vinyl chloride, which connects the two attachment portions 10 and 10 to each other on the back side, and by inserting an end of the panel 8 into the attachment portion 10. , Two panels 8, 8 with a hinge 9,
They are connected so that they can be bent at right angles from the folded state.

The upper and lower ends of each panel 8 are shown in FIG.
A horizontal frame member 12 made of a hard synthetic resin having a U-shaped cross section shown in FIG.

Attachment portion 10 of hinge 9 and horizontal frame member 12
In the case of FIG. 4 (C), the fixing of the panel 8 to the panel 8 is performed by using a strong adhesive tape 13 and affixing it over the inner surface side of the panel 8 and the mounting portion 10 or the horizontal frame member 12. This portion can be fixed using rivets or tapping screws, but the method of fixing with an adhesive tape 13 is the simplest including maintenance.

In FIG. 4C, a hollow sheet made of polypropylene is used for the panel 8.
A single plate such as a synthetic resin plate, various plywoods, a composite plate, and an aluminum plate can also be used.

FIG. 5 shows a second example of the rectangular cylindrical case 4,
Each panel 8 is a single plate. Adjacent ends of each panel arranged in a rectangular tube shape are formed of a soft polypropylene tape 14 having a thickness of about 0.2 mm to 0.5 mm. The structure 15 is applied to the panels 8 and 8. It is known that the hinge effect of polypropylene is obtained by integrally forming a thin case in a small case or part of an electric appliance, but there is no hinge having a structure in which a polypropylene tape is attached with a double-sided adhesive tape. Did not.

Next, as shown in FIGS. 2A and 3, the lower frame 3 on which the rectangular cylindrical case 4 is mounted is made of an angle material so that the lower portion of the rectangular cylindrical case 4 fits outside. The assembled rectangular frame 16 and the frame 1 at the lower four corners of the frame 16
The frame 16 includes a receiving plate 17 which is fixed so as to protrude to the outside and supports a lower end of the rectangular tubular case 4, and a height-adjustable grounding member 18 which is also attached to the lower four corners of the frame 16.

A top plate 5 placed on the rectangular cylindrical case 4
As shown in FIG. 3, a peripheral frame 20 is fixed to a lower portion around a top plate 19 which is slightly larger than the outer diameter of the rectangular cylindrical case 4, and a concave portion is formed in a lower portion of the top plate 19. 2
0 is fitted to the upper end of the rectangular cylindrical case 4.

At the top surface of the top plate 5 near the outer periphery, a flat rectangular groove 21 is provided, and a synthetic resin groove member 22 having a U-shaped cross section is embedded in the groove 21. 5, the transparent case 2 can be mounted.

The transparent case 2 includes four transparent plates 6a, 6b, 6c, 6d using a transparent acrylic material or a glass plate.
Are arranged in a rectangular tube shape, and the upper frame 7 is mounted on this transparent plate.

Each of the transparent plates 6a, 6b, 6c, 6d is shown in FIG.
As shown in the figure, both ends in the vertical direction are cut into 45 ° inclined surfaces 23, and when arranged in a rectangular tube shape, the inclined surfaces come into contact with each other, so that the corner is finished at a right angle,
As for a pair of two transparent plates 6a and 6b which are arranged to face each other, an angle member 24 is fixed to the outer surfaces of both ends in the longitudinal direction by means such as bonding so that one side thereof projects perpendicularly to the inclined surface 23 side. The angle member 24 is not fixed to the remaining two transparent plates 6c and 6d.

As shown in FIG. 3, an upper frame 7 mounted on the group of transparent plates 6a, 6b, 6c, and 6d includes a frame member 25 formed by using an angle member to have a planar rectangular shape, 25, an inner frame member 27 fixed to the outer periphery at the lower surface of the ceiling plate 26, and grooves formed between the frame member 25 and the inner frame member 27 are formed in the transparent plates 6a to 6a. 6d.

To assemble the transparent case 2 on the top plate 5,
The one transparent plate 6a on which the angle material 24 is stuck is
The transparent plates 6c and 6d, on which the angle material is not stuck, are set at the opposing positions, and the exhibit is set on the top plate.
The remaining transparent plate 6b on which is adhered is set up.

Each of the transparent plates 6a, 6b, 6c, and 6d has a lower end portion elastically held by a channel member 22, and an end surface on both sides in contact with an inclined surface 23, which is held by an angle member 24. Moreover, since the upper frame 7 is fitted to the upper ends of the transparent plates 6a, 6b, 6c, 6d, the entire transparent case 2 is assembled firmly. Also, if the length of the transparent plate is as long as about 1 m, the transparent plate itself may be warped and difficult to assemble in the conventional method. However, as in the present invention, both ends in the vertical direction are inclined by 45 °. If the cut is made on the surface 23 and the butt is held by the angle member 24, the insertion work from the lateral direction can be easily performed, and the butt portion becomes wedge-shaped so that the warp of the transparent plate can be absorbed and the appearance is improved. At the same time, the angle member 24 may have a small cross-sectional dimension.

The display case of the present invention is configured as described above. The lower part of the rectangular cylindrical case 4 is externally fitted to the lower frame 3 and the top plate 5 is placed on the rectangular cylindrical case 4 to display the display. 1
