Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for reinforcing a shelf board in a moving shelf or other document storage shelf device.

[0002]

2. Description of the Related Art Conventionally, a shelf board of this type employs, for example, a single plate made of steel as a substrate as it is when a lightweight one is mounted thereon, and when a heavy one is mounted, As shown in FIG.
3 was spot-welded to have a structure resistant to deformation and the like.

[0003]

[Problems to be Solved by the Invention] As described above, it is necessary to prepare separate shelves in the production stage due to the weight of the products to be mounted conventionally, and there is a problem that two types of product stock must always be prepared. Was. In addition, when a shelf for a heavy weight is requested in place of a shelf for a light weight on the spot, it often happens that it is not possible to respond immediately. In addition, a heavy shelf board involves a troublesome work of spot welding a reinforcing material to the back surface, and there is an inconvenience that, after completion, it cannot be applied to a light-weight shelf board.

[0004] The present invention solves the above-mentioned problems of the conventional shelf, and does not distinguish between heavy and light at the production stage. It is an object of the present invention to provide a reinforcement structure for a shelf plate that can be easily assembled on-site when it is used for a weight shelf plate by being set.

[0005]

According to the present invention, as a specific means for achieving such an object, a leg 1 is provided on both left and right sides.
a, 1a, shelf supports 2, 2 disposed before and after the substrate 1, and a reinforcing material 3 disposed on the lower surface of the substrate 1 between the two shelf supports 2, 2 Notches 3a, 3a are provided at positions before and after the reinforcing member 3, and the notches 3a of the reinforcing member 3 are provided in the shelf supports 2, 2.
hooks 2 for positioning reinforcing material at positions corresponding to a and 3a
a, 2a, and protruding portions 2 at the lower edges thereof which engage with the inner portions 1b, 1b of the legs 1a, 1a of the substrate 1, respectively.
The present invention proposes a shelf board reinforcing structure characterized by providing b and 2b.

[0006]

The reinforcing member 3 is positioned only by aligning the notches 3a, 3a with the hooks 2a, 2a of the front and rear shelf receivers 2, 2, and the substrate 1 is positioned above the front and rear shelf receivers 2, 2.
By merely storing the space between the two, the legs 1a, 1a of the board 1 and the protrusions 2b, 2b of the shelf receivers 2, 2 are engaged with each other, and a reinforcing structure of the shelf can be realized.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an assembled state of a reinforced shelf according to the present invention, and FIG. 2 is a cross-sectional view showing a state where the assembly is completed.

In FIG. 1 and FIG. 2, a substrate (lightweight shelf) 1 is made of, for example, a rectangular flat plate having legs 1a, 1a formed by roll forming on both left and right sides of a mild steel plate. Shelf receivers 2 and 2 are arranged at positions before and after the substrate 1. Reference numeral 3 denotes a reinforcing member disposed between the shelf supports 2 and 2 on the lower surface of the substrate 1, and formed with rising portions 3b and 3b on both left and right sides to prevent deformation of the substrate 1. It has a structure that can withstand.

At the front and rear positions of the reinforcing member 3, a notch 3
a and 3a are provided. Further, hooks 2a, 2a for positioning a reinforcing member are provided at positions corresponding to the notches 3a, 3a in the shelf receivers 2, 2, and the reinforcing member 3 has the notches 3a, 3a in front and rear of the shelf receivers. 2, 2 hooks 2a, 2
It is positioned only by adjusting to a, and is prevented from moving in the front-back and left-right directions.

On the other hand, projections 2b, 2b are formed on the lower edges of the shelf supports 2, 2, respectively. When the substrate 1 is stored between the shelf supports 2, 2 from above, the legs 1a, 1a of the legs 1a, 1a are formed. Engagement with the inner portions 1b, 1b prevents the substrate 1 from moving in the front-rear and left-right directions.

In order to assemble the shelf board in this embodiment,
The reinforcing member 3 is mounted between the shelf supports 2 and 2 arranged in front and back with the cutouts 3a and 3a and the hooks 2a and 2a of the shelf supports 2 and 2 matched. Next, the substrate 1 is inserted between the front and rear shelf supports 2 and 2 by the inner portions 1b and 1b of the legs 1a and 1a.
And the projections 2b, 2b formed on the lower edges of the shelf supports 2, 2 are engaged and stored, thus completing the operation.

[0012]

As described above, according to the reinforcing structure for a shelf board according to the present invention, the following effects can be obtained. If you want to put a lightweight one on the shelf, use the board as it is,
When the object to be placed is a heavy object, the reinforcement structure of the shelf can be realized by a simple operation of storing the substrate in a state where the reinforcing member 3 is mounted between the two shelf receivers 2 and 2. Therefore, when a shelf for weight is required in place of a shelf for light weight at the site, it can be immediately coped with only by simple assembling in which the reinforcing material 3 is interposed on the lower surface of the substrate 1, as in the conventional case. In addition, there is no need to prepare separate shelves for weight and light weight in the production stage. And when assembling,
Of the hooks 2a, 2a and the notches 3a, 3a of the reinforcing member 3, and the inner portions 1b,
1b and projections 2b, 2b formed on the lower edges of the shelf supports 2, 2.
Only the simple operation of engaging with the reinforcing member is required, and the troublesome work of spot-welding the reinforcing member is not required. Further, by removing the reinforcing member after completion, the light-weight member can be easily replaced.
