Description

[Detailed Description of the Invention] This invention relates to a pipe joint member and a foldable product display shelf using the same, and in particular, the joint part of the pipe joint is separated into two parts so that the tip part can be rotated horizontally. The present invention also relates to a foldable product display shelf assembled using the pipe joint member.

In recent years, prefabricated shelves have become the mainstream for product display shelves, but pipes, pipe fittings, and other components are transported to the department store sales point where products are displayed, and the shelves are assembled into appropriate shapes there. requires skilled acquisition and additional labor time. Due to the convenience of department stores and stores that display products,
This work is usually done for a short period of time on limited days such as store holidays, and is usually carried out at the same time as the replacement work. However, with on-site assembly methods, problems often arise in mobilizing skilled workers and limiting work time.

Therefore, a method has been considered in which shelves are assembled in advance at a workshop such as a factory and then transported to a display site such as a department store. However, transporting and moving the entire assembled shelf is not only inconvenient due to its size, but also very inefficient. It may be possible to assemble it to some extent in a factory and then transport it as a semi-finished product, but it will still need to be obtained on site.
It is also being considered to make the shelves foldable so that they can be folded during transportation to improve transportation efficiency. However, the folding shelves that have been developed to date have the major drawback that they can only be provided that meet certain specific standards. In other words, mechanical processing has been added to make the shelves foldable, so although the shelves can be folded together, the structure usually does not allow for the addition of shelves or other appropriate changes. . If you want to change the size, length, or depth of the shelves depending on the display situation at a department store or store, standard folding shelves will not suffice, so you can order custom-made folding shelves from the factory in advance. , we had to take into account the extra production time. This also had the disadvantage that the shelves themselves were relatively expensive. In particular, there were circumstances in which we were unable to accommodate such special orders for the shelves for shipping.

Therefore, it became necessary to devise a shelf that was equipped with a folding shelf mechanism and that could be arbitrarily assembled into any shape.

An object of the present invention is to provide a new assembly-type product display shelf that eliminates the drawbacks of the prior art as described above, and which has a structure that is both assembly-type and foldable. .

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 is a perspective view of a product display shelf assembled with an assembled shelf folding device according to the present invention. The assembled product display shelf 10 consists of a vertical pipe member 11 and a horizontal pipe 1.
2 and a depth pipe member 13, and the depth pipe member 13 is structured to rotate horizontally by 90 degrees. FIG. 2 is a diagram showing the assembled product display shelf in a folded state. In this embodiment, one end of each depth pipe 13 is 90 degrees to the right.
If the shelf rotates 90 degrees, the other end rotates 90 degrees to the left, and all the depth pipes making up the entire shelf move in the same way. Also, if one end rotates 90 degrees to the left, the other end will rotate 90 degrees.

It is also possible to vertically fold the shelf by rotating the depth pipe member 13 90 degrees vertically.

FIG. 3 is a perspective view showing a bendable pipe joint member used in the folding shelf according to the present invention. The pipe joint member 20 has a structure in which one or more pipe fitting parts 22 are integrally joined at a cube root part 24 so as to be perpendicular to each other. Pipe insertion part 22
It has a slightly tapered structure. The outer diameter of the pipe fitting portion is configured to match the inner diameter of the cavity of the square pipe member 30, and is fitted into the cavity of each square pipe.

The bending joint part 40 that fits and supports the deep pipe is composed of a pipe fitting part 42 and a base part 44, and a concave holding part 46 is provided at the end opposite to the base part from which the pipe fitting part protrudes. ing. The base portion 44 of the bending joint portion 40 has the same width as the root portion 24 of the cube, and has the same width as the outside of the depth pipe member 13, so that the assembled shelf is configured flush. It's summery. Furthermore, a support portion 26 is provided protruding from the cubic base portion 24 .

The support part 26 has a thickness of about 1/3 of the thickness of the base part 24, and has a semicircular flat plate shape, and a through hole 27 is bored in the center thereof. Also, Motobu 4
4 also has a through hole 47 bored in its center, passing through the upper and lower pieces forming the recess and reaching the lower end. The thickness of the supporting portion 26 is approximately the same as the thickness of the recessed portion of the gripping portion of the base portion,
The support part can be inserted into and held by the clamping part.

After inserting the support part, the flat plate-shaped fixing pin 50 made of steel is
The supporting part and the bending joint part are fixed by rolling it up and inserting it with pressure.

Half of the tips of the upper and lower pieces of the recess are formed so as to come into contact with the base 24 and fix the shelf in the assembled state, and the other halves are formed in a circular shape. As a result, in this embodiment, the bending joint part is configured to rotate 90 degrees to the left and stop when it comes into contact with another fitting part. FIG. 4 is a plan view of the shelf in a folded state (see FIG. 2), and the third
The pipe joint member shown in the figure corresponds to that indicated by A. To configure one shelf,
A different type of pipe fitting member than that shown in this example would be required. That is, all of these modifications have the same basic structure as that shown in FIG. 3, although some are required in the opposite direction.

FIG. 5 shows a shelf support member 60 that also serves to prevent the assembled folding shelf from swinging, and has a U-shaped crotch 62.
Straddle each square pipe member from above,
By fixing the shelf and placing a shelf made of glass or the like on the shelf holder 64, shaking of the shelf can be effectively prevented.

In addition to the above-mentioned effects, as shown in Fig. 6, the pipe joint member according to the present invention can be stopped at any angle. You can create a modified shelf. In this case, a special fixture is used to fix the shelf at an intermediate angle, and a pipe member of a specific length different from the standard one is used.

Since the assembly shelf folding device according to the present invention has the configuration as described in detail above, it has the great advantage that various shapes can be easily formed compared to conventional folding shelves that have a single pattern. In addition, the folding method can be freely determined from left to right, and at the same time, it is also possible to fold up and down. Furthermore, whereas conventional shelves were fixed at 90 degrees, the present invention can be fixed at any angle, allowing the user to freely assemble the shelves no matter what the shape of the room. effective.
