DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a brace mounting structure for a shelf on which a brace for reinforcing a shelf for displaying and storing articles is mounted.

[0002]

2. Description of the Related Art In such a shelf, for example, two braces 16, 16 are attached between left and right supports in a crossed state as shown in FIG. 1 in order to reinforce the shelf itself. I have. Conventionally, each of the braces is shown in FIG.
And as shown in FIG. In other words, at each end of the rod-shaped brace 16 having a circular cross-section,
Substantially U that is engaged with slits 7a formed in the right and left columns 7
係 止 -shaped engaging portion 16K is provided.

[0003] The substantially U-shaped locking portion 16K of the brace 16 having the above-described configuration is connected to the slits 7a of the rear left and right columns 7,9,
9a (only one pillar 7 is shown in the figure) to make each brace 16 in a tensioned state, or to engage the locking portion 16K with slits 7a, 9a of the left and right pillars 7,9.
After that, the brace 16 is tensioned by operating a turn buckle or the like provided in the middle part of the brace 16 to reinforce the shelf.

However, since the locking portion 16K has a substantially U-shape, when the brace 16 is tensioned, the locking portion 16K and the column 7 or 9 are in point contact only at two places. In other words, as shown in FIG. 23, the tip of the locking portion 16K makes point contact with the inner surface of the column 7 or 9, and the portion of the locking portion 16K facing the locking hole 7a and the corner of the locking hole 7a. The part is in an unstable state with point contact. For this reason, the position of the locking portion 16K with respect to the column 7 or 9 may be changed unexpectedly, and there has been an inconvenience that the brace 16 cannot be stably tensioned. In addition, the slits 7a which are particularly weak in strength among the portions of the columns 7 or 9
Or, since the tension of the brace acts intensively around 9a, if the tension of the brace is increased, it may not be able to withstand this tension and the portion may be damaged.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and aims to solve the problem by devising the shape of the brace so that the position of the locking portion with respect to the column is not changed unexpectedly. In addition, the brace can be stably tensioned without damaging the column.

[0006]

According to the present invention, in order to solve the above-mentioned problems, the pillars are erected at four corners of a rectangular plane whose opposing sides are parallel to each other, and two pillars are located at the front and rear of the pillars.
The pairs of columns are connected to each other by a first connecting member having a width smaller than the width of the columns, and the two columns located on the left and right are connected to each other by a second connecting member. A plurality of shelves are provided at predetermined intervals in the vertical direction between the four columns, and a locking hole for locking a bar-shaped brace for tension is provided between the columns adjacent in the horizontal direction. A brace mounting structure for a shelf formed at the end of the brace which has entered the inside of the support column through the locking hole, and a first contact portion for linearly or surface-contacting the inner surface of the support column at the end of the brace. At the same time, at the position of the brace near the locking hole and outside the support,
A second contact portion is provided on the outer surface of the column facing away from the locking hole, the second contact portion being in line contact or surface contact. That is, since the first contact portion and the second contact portion contact the inner surface and the outer surface of the column, respectively, the movement of the brace in the insertion direction into the locking hole is prevented. This can be maintained even when the tension is applied. Moreover, the tension of the brace is not concentrated only in the vicinity of the locking hole of the column, but is dispersed through the first contacting portion and the second contacting portion at a portion away from the locking hole of the column. .

The column is formed in a rectangular cross section having four side surfaces having corners located in the front, rear, left and right directions, and the corners of the columns located in the front and rear are connected to each other by the first connecting member. Since the second contact portion is brought into contact with an outer surface of a pillar extending from a locking hole formed on one of the four side surfaces to a corner located on the inner side of the locking hole, the second contact portion is provided. Among the parts, the tension of the brace can be dispersed toward the corner of the pillar that is most advantageous in terms of strength.

A tension portion is provided for forcibly moving the plurality of braces provided between the columns which are adjacent in the left-right direction to a side where they come close to each other, thereby bringing them into a tension state. Thus, the braces move in any direction that intersects them, placing them in tension. By the way, when the brace is tensioned by the turn buckle, tension is applied only in one direction along the longitudinal direction of the brace. If it is not formed accurately,
In the case of the turnbuckle, it is necessary to apply tension in a well-balanced manner, but in the case of the present invention, the accuracy error can be absorbed by movement of the brace in any direction intersecting with the brace, and the entire brace can be balanced. Tension can be applied.
