Description

[Detailed Description of the Invention] Industrial Field of Use The present application relates to a shelf board in a document cabinet on which books, documents, etc. are placed.

Conventional Technologies and Problems Conventionally, in document shelves on which magazines, books, etc. are placed, a large number of locking holes for attaching shelf boards are spaced along the height direction at the front and back positions of the inner surfaces of the left and right side walls of the housing. The above-mentioned locking of the shelf bracket is made by integrally providing a mountain fold-shaped locking portion at the rear and an upwardly U-shaped receiving portion at the front in each of the left and right front and rear locking holes at the same height position. At the same time, an edge of a shelf board formed by bending downward from the periphery of the rectangular upper plate and further bending the lower edge inward is placed on the receiving part. Therefore, multiple shelves are arranged inside the housing.

However, according to the above-mentioned known shelf board, when the shelf board is placed on the shelf bracket, a gap at least equivalent to the material thickness of the receiving part is created between the inner surface of the side wall of the housing and the side surface of the shelf board. Therefore, there are defects such as not being able to effectively use the full horizontal width of the shelf board for placing documents, etc., and paper sheets such as documents entering through this gap and damaging the documents. death,
Furthermore, the receiving portions of the shelf brackets also bulge out on the lower surface of the shelf, and when documents placed on the lower shelf are taken out, they get caught and damage the documents.

Purpose, Examples, and Effects of the Invention Therefore, the present invention solves the above-mentioned conventional defects by configuring so that no gap is created between the side surface of the shelf board and the inner surface of the side wall of the case. To explain in detail, 1 is made by bending the rear edge and left and right side edges of a horizontally rectangular upper plate 2 made of a metal plate vertically downward, and then bending the lower edge inward to form an edge 3, 4, 4, the front edge of the upper plate 2 is bent into an arc shape, and the bent piece 5 is extended inward for a relatively long time. Preferably, as shown in this example, at least in the front and back positions of the lower half of the vertical plane of the left and right edges 4, the entire lower half 6 is placed between the upper half 7 and the material thickness t of the shelf bracket 8. It is formed by forming a recessed part 9 that is recessed inward so that a step corresponding to the height of the recessed part 9 is formed. 1
0 is a plurality of locking holes provided in the front and back positions of the inner surface of the left and right side walls 11 of the housing A, respectively, in the height direction; 14 is a reinforcing piece;
Reference numeral 16 designates notches on the left and right sides of the lower surface of the front edge of the shelf board 1 for insertion of the shelf brackets 8.

As is well known, the shelf bracket 8 has a locking portion 12 bent in a mountain-fold shape that locks into the locking hole 10 at the rear, and an upwardly U-shaped receiving portion 13 at the front thereof.
Therefore, in the present application, when a shelf is placed on the shelf holder 8, the shelf holder 8 protruding from the lower surface of the shelf allows the shelf to be placed on the lower level. In order to prevent the upper part of the document from getting caught on the shelf holder 8 and damaging the document when taking out documents, etc., the shelf holder 8 is placed at the front and rear of the lower sides of the left and right edges 4 of the shelf board 1. A recessed portion 15 corresponding to the material thickness t of the receiving portion 13 is provided.

However, when using the left and right side walls 1 of the housing A,
The locking portions 12 of the shelf bracket 8 are respectively locked in the locking holes 10, 10 provided at the front and back positions of the inner surfaces of the shelves 1 and 11 at the same height, and in this state, the left and right edges 4, 4
is placed on the receiving part 13 of the shelf bracket 8 so that the recessed part 15 fits, and in this state,
The rear hanging piece of the shelf bracket 8 intervenes in the recess 9, and the upper half 7 of the edge 4 comes into contact with the inner surface of the side wall 11.

Effects of the invention As described above, according to the present application, the shelf board can be placed on the shelf bracket so that the side surface of the shelf abuts against the inner surface of the side wall of the housing. There is no risk of paper sheets such as documents getting in and damaging the shelf, and the entire horizontal width of the shelf board can be used effectively for placing documents, etc., and the bottom surface of the shelf board is designed to accommodate shelf brackets. Since the portion does not bulge out, there is an advantage that when taking out documents placed on the lower shelf, there is no risk of them getting caught and being damaged.
