DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a base leg and a support of a display stand used for displaying products in a supermarket or other stores.

[0002]

2. Description of the Related Art As a prior art of this type of display stand, there is one disclosed in, for example, Japanese Utility Model Laid-Open Publication No. 63-175963.

In this display stand, a substantially horizontal base shelf is erected between a pair of left and right base legs facing the front-rear direction, and a lower end of a column for supporting the shelf and the like is provided at an intermediate portion between the two base legs. The part was attached and the space between the left and right supports was covered with a decorative plate.

[0004] The base leg is made of a channel material having a U-shaped cross section which can be formed by shearing and pressing, and the lower end of the column is fitted into the inside of the base leg through an opening provided on the upper surface of the base leg. The support and the base leg are fixed by fixing means.

[0005]

In order to install a base shelf between base legs, a bracket is fastened to the base legs.
It is common to support the base shelf with this bracket. However, in the above-described conventional example, since the base leg is a channel material having a U-shaped cross section, when the bracket is fixed to the upper surface of the base leg, a load of a product or the like placed on the base shelf board is transmitted through the bracket. When it hangs on the upper surface of the base leg, the base leg may be deformed. Also, when a strong lateral force is applied to the support, the base leg may be deformed.

In order to solve such a drawback, it is conceivable that the base leg is formed in a tubular shape, a mounting hole is formed in the upper surface thereof, the lower end of the column is inserted into the mounting hole, and the column is mounted on the base leg. .

If the base leg is formed in a tubular shape, the strength of the base leg is improved. Therefore, even when the bracket is fixed to the base leg or when a large lateral force is applied to the column,
The risk of deforming the base leg is reduced.

However, since such a base leg has to be formed into a tubular shape by, for example, drawing a metal material, a mounting hole must be formed in the surface thereof. Therefore, the base leg is formed by shearing and pressing. The cost is higher than in the case.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a low-cost, high-strength mounting structure for a base leg and a column of a display stand. And
