Description

The present invention relates to a shelf board receiving structure and a non-welding type shelf board receiving device, and more particularly to a receiving structure and a receiving tool in which a shelf board such as a bookshelf or a display shelf is fixed to a shelf receiving leg or the like without welding.

For example, when attaching a shelf board to a support column, a method is known in which a slit is provided in the support column, the rear hook of the bracket is inserted into the slit, and the shelf board is supported by the bracket. However, the engagement between the slit and the locking hook of the bracket is known. Since there is a gap in the part, it may be disengaged, rattled, or tilted.

On the other hand, there has been proposed a receiving structure in which a holding metal fitting is inserted into a slit and a shelf plate received by the bracket is held by the holding metal fitting (Patent Document 1).

Further, a receiving structure has also been proposed in which a projecting piece is fitted in a gap between a slit and a locking hook, and a bracket is fixed without a gap to fix a shelf plate without slack (Patent Document 2).

Further, a receiving structure has been proposed in which the base portion of the presser fitting is inserted into the slit and the presser fitting is twisted to strongly press the shelf board (Patent Document 3).
