DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a base side plate in a commodity display stand.

[0002]

2. Description of the Related Art Conventionally, a base side plate in a commodity display stand is formed by bending the upper and lower edges and the front and rear edges of a single thin steel sheet inward to each other to form a shallow box frame shape, and bending the front edge thereof. The hooks which are inserted into the locking holes of the pillars and locked are formed integrally at the end edges of the pillars.

[0003]

Since the base side plate in the above-mentioned conventional product display stand is formed by bending only one thin steel plate, the strength of the hook piece can be sufficiently obtained. I didn't. For this reason, when the strut is twisted or oscillated in the horizontal direction due to the load while the hook is locked in the locking hole of the strut, the hook is bent and rattling occurs, and the base side plate is fixed to the strut. However, there was a problem that it was very unstable and inferior in strength.

[0004] On the other hand, the present applicant has disclosed a side plate main body having a bent hook piece as a base side plate in a commodity display stand which solves such a problem, and a hook having the same shape as the hook piece of the side plate body. Japanese Patent Application No. Hei 6-218151 proposes a base side plate for a product display stand in which a reinforcing plate provided with pieces is superposed and integrated by welding to increase the overall strength.

[0005] However, in the prior art, it is necessary to weld the hooks of the side plate main body and the hooks of the reinforcing plate so as to be correctly aligned with each other. Since the hooks to be hooked on each other have a two-layered structure formed by polymerization, there is another problem that the strength is further deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to increase the overall strength with a simple structure and reduce the manufacturing cost. The object of the present invention is to obtain a base side plate for a simple product display stand.

[0007]

In order to achieve the above object, the base side plate of the commodity display stand according to the present invention is formed by bending the upper and lower edges and the front and rear edges of a single metal plate inward at right angles. And a side plate body having a vertically elongated hole formed in a bent portion of a rear edge closely contacting the column, and protruding outward from the vertically elongated hole of the side plate body to be inserted into a locking hole of the column. And a metal reinforcing plate provided with upper and lower hooks that are locked by locking.The stepped portion at the front end of the metal reinforcing plate is superimposed on the inner surface of the side plate main body and fixed by welding, and the bent portion at the lower end is formed. The side plate body and the metal reinforcing plate are integrated by welding and fixing to the bent portion at the lower edge of the side plate body.

Preferably, the metal reinforcing plate is formed of a metal plate thicker than the side plate main body.

Therefore, in the present invention, the hooks of the metal reinforcing plate may be integrated by welding while protruding outward from the vertically long holes of the side plate main body, thereby facilitating manufacture and reducing costs. It becomes possible.

Also, since the hooks of the metal reinforcing plate are correctly positioned at the center so as not to be displaced from side to side by the vertically long holes of the side plate main body, and are firmly supported and reinforced, the support columns are twisted and laterally bent. It is possible to obtain a base side plate in a commodity display stand that is excellent in strength without bending of the hooks even against runout.

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a product display stand to which the present invention is applied, FIG. 2 is a perspective view of a base side plate according to the present invention, and FIG. 3 is an exploded perspective view of the base side plate. In FIG. 1, reference numerals 1 and 1 denote a pair of right and left columns, 2 a base side plate,
3 is a kick plate, 4 is a stage shelf, 5 is a backboard, 6 is a trim cover, and 7 is a shelf board.

As shown in FIGS. 2 and 3, the base side plate 2 is formed by bending the upper and lower edges of a metal plate made of a single thin steel plate inwardly at right angles, respectively, to form bent portions 8a having a U-shaped cross section. 8b, the front and rear edges are bent inward at right angles, and the side plate main body 10 is formed with bent portions 9a and 9b having an L-shaped cross section, and upper and lower hook pieces 12a and 12b are formed to project from the rear edge. And a metal reinforcing plate 11.

In the bent portion 9a at the rear edge of the side plate body 10, vertically long holes 13a and 13b are formed so as to face the upper and lower hook pieces 12a and 12b of the metal reinforcing plate 11, and the bent portion 8b at the lower edge is formed.
Is mounted with an adjusting bolt 14 for height adjustment.

The metal reinforcing plate 11 is formed by pressing a steel plate having a thickness about twice that of the side plate main body 10, and is superposed on the inner surface of the side plate main body 10 at the front portion from the center thereof. A stepped portion 15 is formed, and a side plate main body 1 is provided at a lower end.
A bent portion 16 joined to the lower edge bent portion 8b is formed.

The side plate body 10 and the metal reinforcing plate 11 are
The upper and lower hooks 12a, 12b of the metal reinforcing plate 11 are
The bent portion 9a of the rear edge is made to face the vertically long holes 13a and 13b.
And the stepped portion 15 is overlapped on the inner side surface of the side plate main body 10 and fixed by spot welding 17, and the tip of the bent portion 16 is joined to the bent portion 8 b at the lower edge of the side plate main body 10. Then, it is fixed by welding 18. Thereby, the base side plate 2 having sufficient strength is obtained by integrating the side plate main body 10 and the metal reinforcing plate 11.

In order to attach the base side plate 2 of the present embodiment configured as described above to the column 1, the base side plate 2 is first inclined as shown by a chain line in FIG. Then, the base plate 2 is placed in a horizontal state as shown by the solid line in the figure, and the hook 12a is inserted into the locking hole 20. At this time, the U-shaped lock member 21 slidably provided in the hollow portion of the column 1 is pushed upward as shown by the chain line in FIG. 4 by contact of the upper hook piece 12a, and the upper hook piece 12a is At the same time when the lock member 21 is completely inserted into the lock member 20, the lock member 21 is released from being pushed up and descends by its own weight, and engages with the upper hook piece 12a as shown by the solid line in FIG. Thereby, the base side plate 2 can be firmly attached to the column 1. When the base side plate 2 is removed from the column 1, a rod member may be inserted into the small hole 22 of the lock member 21 from outside the column 1 and the lock member 21 may be slid upward. 23 is pillar 1
