Description

[Detailed explanation of the idea] B Industrial application field The present invention relates to a foldable display case.

B. Prior Art Conventionally, there is a foldable display case in which each component wall is separated, but in this case, the separation and assembly work is troublesome. Therefore, Mikoaki
As disclosed in No. 50-20625, the side wall plates are divided and connected with hinges, and when folded, the side wall plates are folded inward like an accordion and brought close to the front and rear walls, making the entire case flat. There are some that are foldable. However, in this case, when folded, the top plate is completely removed from the main body frame and stored in the folded case, which requires time and effort to store the top plate. There is also concern about the strength after assembly.

C. Purpose of the invention In view of the above, the present invention is designed so that both side wall plates can be folded in an accordion style, and the top plate can be transformed into a horizontal usage state at the upper end of the rear wall of the case body and a vertical usage state where it lies down on the rear surface of the rear wall. It is rotatably connected to the top plate so that each component including the top plate can be folded without separating, making folding and assembly operations convenient.Furthermore, the folded form can be folded into a flat vertical position, allowing it to be placed in a corner of a room, etc. To provide a show case that can be placed without taking up much space, has a top plate rotation mechanism that is easy to install, and is stable even after assembly.

D. Structure of the invention In order to achieve the above object, the present invention divides both side walls 3, 3 into a front side wall 3a and a rear side wall 3b, and connects these so that they can be bent inward by a hinge 6. The side wall 3a is attached to the front frame 1, and the rear side wall 3b is attached to the rear frame 2.
are connected so as to be bendable inwardly by hinges 4 and 5, respectively, and the floor plate 7 is connected to the front frame 1 so as to be rotatable upward,
A top plate 8 is rotatably connected at its rear end to the upper crosspiece 2a of the rear frame 2 so as to be freely openable and closable between a horizontal state and a hanging state along the rear surface of the rear frame 2. The front frame 1 and both side walls 3, 3 are attached to the edge beams 81 on both sides.
A downward protrusion is provided to cover the upper part of the top plate 8.
The rotation mechanism has a mounting piece 8d protruding from the base parallel to the rotation shaft 8c in the longitudinal direction, and the rotation shaft 8c is attached to the rear frame 2.
At both ends of the upper crosspiece 2a, the mounting pieces 8d are inserted into notches at both ends of the rear end crosspiece 8a of the top plate 8, and are secured with screws 9.

Example Next, embodiments of the present invention will be described based on the drawings.

Reference numeral 1 denotes a front frame consisting of an upper crosspiece 1a, a middle crosspiece 1b, a lower crosspiece 1c, and both side pillars 1d, 1d, into which glass is fitted to form a front wall. Casters 1e are provided on the lower surface of the lower crosspiece 1c. 2 is upper rail 2
a, a rear frame consisting of an intermediate crosspiece 2b, a lower crosspiece (not shown), and both side pillars 2d, into which a glass door is fitted to form a rear wall. After this frame 2
A caster is also provided on the underside of the. Reference numerals 3 and 3 denote both side walls, each of which is divided into a front wall 3a and a rear wall 3b. The front wall 3a is connected to the side post 1d of the front frame 1 by a hinge 4 so as to be rotatable inward. The rear wall 3b is connected to the side post 2d of the rear frame 2 by a hinge 5 so as to be rotatable inward. Furthermore, these front side wall 3a and rear side wall 3b are connected by a hinge 6. Reference numeral 7 denotes a floor plate connected to the intermediate crosspiece 1b of the front frame 1 with a hinge so that it can be raised and lowered.The plate area is approximately the same as that between the front and rear frames 1 and 2 when the front frame 1 and the rear frame 2 are expanded to the usage configuration. The rear end edge of the floor plate 7 is set to engage with the intermediate crosspiece 2b of the rear frame 2. Reference numeral 8 denotes a top plate, and a rear end crosspiece 8a is connected to the upper crosspiece 2a of the rear frame 2 so as to be rotatable in the front-rear direction. This connection structure is as shown in FIGS. 8 and 9. That is, an upwardly rising wall 2e and a cylindrical portion 2f projecting rearward from the rising wall 2e are integrally molded at the rear of the upper crosspiece 2a of the rear frame 2, and the left and right sides of the rear end crosspiece 8a of the top plate 8 are integrally formed. A hollow portion 8e is provided at the end of the joint member 8f at a portion where the joint member 8f comes into contact with the joint member 8f, and a mounting piece 8d and a rotating shaft 8c are provided protruding from the base 8b of the joint member 8f, so that the mounting piece 8d is hollow. The top plate 8 is inserted into the portion 8e and is provided so as to rotate back and forth about the rotating shaft 8c as a fulcrum. Furthermore, the edge rail 81 of the top plate 8 is designed to cover the front frame and the side frames.

In the figure, 9 is a screw, which fixes the joint member 8f to the abutting portion of the rear end crosspiece 8a of the top plate. 10 is a shelf post, 11 is a shelf support, and 22 is a shelf board.

F Operation To fold it from the use state shown in FIG. 1, first open the top board 8 backward as shown in FIG. 2 with the rotation shaft 8c as a fulcrum, and hang it down from the rear surface of the rear frame 2 as shown in FIG. 3. Next, as shown in FIG. 3, the shelf board 1
2. Remove the shelf support 11 from the upper opening. Next, as shown in Fig. 4, raise the floor plate 7 forward with the hinges at the front edge as fulcrums. Next, press the both side walls 3, 3 inwards from the outside to raise the front wall 3a.
The front and rear walls 3a and 3b are rotated inward by hinges 4, 5, and 6, and both side walls 3, 3 are folded as shown in Fig. 5. Next, the front frame 1 and the rear frame 2 are pressed inward so that they approach each other, and both side walls 3, 3 are folded so that the front and rear walls 3a and 3b are parallel to each other. This causes the entire case to be folded flat as shown in Figs. 6 and 7. The front and rear frames 1, 2 can be easily moved by the casters 1e provided on each of them.

Next, in order to transform the folded form described above into the usage form shown in FIG. 1, the operation is reversed.

G. Effects of the invention As described above, according to the invention, each component wall including the top plate can be folded and assembled without separating, so the folding and assembly work is extremely convenient. Since it has a flat shape with both side walls retracted inward, it becomes compact when not in use, making storage convenient. Furthermore, the rotating part of the top plate 8 can be easily folded by simply inserting the rotating shaft and mounting pieces from both rear ends and fixing them with screws. Since the tops of the front frame and side frames are covered with crosspieces, it can be held firmly.
