Thus, the reinforcement band piece 14 can be effectively installed by very simple work (operation). The installed reinforcement band piece 14 has both end parts brought into contact with the inner surfaces of vertical outer both reinforcing rib parts 9a, 9a, so that the longitudinal movement can be effectively inhibited so as to prevent the locking pieces 11 from slipping off the locking parts 11a.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin in which a rectangular flat plate member such as a shelf plate or a top plate is assembled and disposed at predetermined intervals in a vertical direction via a column standing at a corner thereof. The present invention relates to a reinforcing structure for preventing deformation of a flat plate member constituting a shelf plate, a top plate, or the like in a storage shelf, a storage case, or the like made of steel.

[0002]

2. Description of the Related Art In general, such storage shelves and storage cases are made of synthetic resin and used for relatively light storage items. Flat plate members constituting a shelf plate or a top plate of a storage case or the like are not considered much in terms of strength, and inevitably warp and distortion occur, and the appearance of the product itself deteriorates, In addition, there has been a problem that the original use of the product is hindered. In order to solve the above-mentioned problems, in the related art, for example, a mechanism for preventing deformation of a plastic storage case described in Japanese Utility Model Registration No. 3036801 has been proposed. In this deformation prevention mechanism, a belt-like reinforcing material is attached to an adjacent portion of the storage case along the front edge of the back surface of the top plate. And a pair of fixing means including a hook-shaped sliding restraining portion whose both ends abut and are fixed by moving back and forth the reinforcing material, and the reinforcing material The intermediate portion is constituted by the front edge and holding means for maintaining a predetermined interval.

[0003]

However, in the above-mentioned conventional structure, although the intended purpose with respect to the top plate can be achieved by mounting the reinforcing material, the assembly with respect to the back surface of the top plate can be achieved. At the time of attachment, one end of the reinforcing member is first deflected once to be deflected while being inserted into the fitting portion, and then the reinforcing member is pulled back to be locked by the fixing means. Due to the configuration, the operation of bending the reinforcing material to be offset and the operation of pulling back and shifting the reinforcing material must be performed, and the assembling work becomes very cumbersome and troublesome, and the workability is increased. In addition, the fixing means is locked by the fitting means formed on the back surface of the top plate, that is, the fixing means positioned outside between the ribs to which the reinforcing material is attached. From, reinforcement Also the entire length of the inevitably of longer, were those that they can not be avoided high cost of the entire product due. Accordingly, the present invention has been made in view of the above-described conventional problems, and has been made to easily and effectively attach a reinforcing strip to a flat plate member constituting a shelf plate or a top plate of a storage shelf or a storage case. It is an object of the present invention to provide a reinforcement structure for a flat plate member in a storage shelf or the like that can perform the above-mentioned steps.

By locating it and pushing it into the slit for insertion from this state, both sides of one longitudinal end face of the reinforcing strip can be engaged with the locking pieces. That is, it is only necessary to move the reinforcing strip in the direction (width direction) orthogonal to the longitudinal direction, and the reinforcing strip can be mounted on the back surface of the flat plate member by a very simple operation (operation). In addition, the length of the reinforcing strip can be arbitrarily set within the dimension between the inner surfaces between the outer reinforcing ribs on the back surface of the flat plate member.

According to a second aspect of the present invention, there is provided a reinforcing structure of a flat plate member in a storage shelf or the like according to the first aspect, wherein a reinforcing strip is provided on a rear surface of the flat plate member in the vicinity of the locking piece in a longitudinal direction. The gist is that support pieces facing each other are formed.

Is inserted obliquely into the space formed by the locking piece and the support piece on one side, and then the other end is inserted into the space formed by the locking piece and the support piece on the other side. The reinforcing strip can be inserted laterally along the longitudinal direction of the reinforcing strip, and in this state, both sides of the reinforcing strip can be directly engaged with the locking pieces.
That is, only the operation of moving the reinforcing strip along the longitudinal direction is sufficient, and the reinforcing strip can be attached to the back surface of the flat plate member by a very simple operation (operation). In addition, the presence of the support piece, coupled with the support by the slit, allows the reinforcing strip to be securely attached.
