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 of product display Kawatana, but it takes skill to transport pipes, pipe fittings, and other components to the site where products are displayed, such as a department store, and assemble the shelves in the appropriate shape. This requires a lot of manpower and a lot of work time. Due to the convenience of department stores and shops 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 the product to some extent in a factory and then transport it as a semi-finished product, but this will still require manpower 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 shelf foldable, so the shelf can be folded in one piece.
Usually, the structure does not allow adding shelves or making 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 be enough, so you can order custom-made folding shelves from the factory in advance and have them manufactured. I had to take into consideration the number of days left. This also had the disadvantage that the shelves themselves were relatively expensive. In particular, there were circumstances in which such special orders could not be accommodated for rental shelves.

Therefore, it became necessary to devise a shelf that was equipped with a folding shelf mechanism and could be quickly assembled into any type of structure.

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

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 depth pipe member 13 is configured to rotate horizontally by 90 degrees. FIG. 2 is a diagram showing the assembled product display shelf in a folded state. In this embodiment, if one of the two ends of each depth pipe 13 is configured to rotate slightly to the right, the other end is configured to rotate to the left.

All the depth pipes that make up the entire shelf are configured to move in the same way. Also, if one end rotates 90 degrees to the left, the other end will rotate to the right.

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

FIG. 3 is a perspective view showing the bendable pipe joint half and material used in the folding shelf according to the present invention. The pipe joint flat member has a structure in which one or more pipe fitting parts n are integrally joined at the root part 24 of a cube so that they are perpendicular to each other.

The pipe fitting portion 22 has a slightly tapered shape. The outer diameter of the pipe fitting portion is configured to match the inner diameter of the cavity of the square pipe member, and is fitted into the cavity of each square pipe.

The bent joint flat 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 6 is provided at the end opposite to the base part from which the pipe fitting part protrudes. It is being The bent joint flat portion 400 and the nine portions 44 have the same width as the root portion 24 of the cube, and have the same width as the outside of the depth pipe member 13 so that the nine assembled shelves are uniformly configured. It has become.

Further, a support portion 26 is provided protrudingly from the base portion C of the cube.

7- The supporting portion has a thickness of about 1/3 of the thickness of the root portion 24, and has a semicircular flat plate shape, with a through hole r in the center.
is perforated. Also in Motobe 44.

A through hole 47 is bored in the center thereof, and the wire hole passes through the upper and lower pieces forming the recess and reaches the lower end. The thickness of the support portion 4 and the thickness of the concave portion of the gripping portion of the base portion are formed to be approximately the same, so that the support portion can be inserted and held in the gripping portion.

After inserting the support part, a steel plate-shaped fixing pin 50 is rolled up and inserted under pressure to fix the support part and the bent joint part.

The tips of the upper and lower parts of the recess are formed so that half of them abut against the base U and fix the shelf in the assembled state.
The other half is circular. As a result, in this embodiment, the bending joint part rotates 90 degrees to the left and stops 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),
The pipe joint member shown in FIG. 3 corresponds to that indicated by A. To construct one shelf, a different type of pipe joint member than that shown in this embodiment is 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 the shelf support that also serves as a member (A) to prevent the sway of the assembled folding shelves. By placing a shelf made of glass or the like on the part 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 shelves. in this case,
A special fixing device is used to fix the shelf at an intermediate angle.
A pipe member with a specific length different from the standard one will be used.

Since the assembly shelf folding device according to the present invention has the configuration as described in detail above, it has a great advantage that various shapes can be easily formed compared to conventional folding shelves that have a single pattern. Also.

At the same time, you can freely decide how to fold left or right.

It can also be folded up and down. Furthermore, whereas conventional shelves had fixed opening angles, the present invention can be stopped at any angle, so the shelves can be assembled freely no matter the shape of the room. effective.
