Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a sleeve cabinet placed below the top of a desk, and a structure of a cabinet that is movable by having casters at the lower end of the cabinet body. It is something.

[Conventional technology and issues to be solved]

In a sleeve cabinet placed on the floor below a desk, or in a configuration in which a drawer is disposed in the main body of a cabinet that can be moved freely on casters, drawer rails are provided on both the left and right outside of each drawer. On the inside of the left and right side panels of the main body,
It is usual to provide a support rail for supporting the drawer rail.

In this case, as disclosed in Japanese Utility Model Publication No. 39-23574, if the side surfaces of each support rail are removably attached to the reinforcing frames on both left and right sides of the cabinet body, Although it is easy to attach and detach the support rail, the bonding strength between the support rail and the reinforcing frame is not strong. Therefore, in order to increase the strength and rigidity of the main body of the cabinet, it is necessary to firmly weld the reinforcing frame to the inner surfaces of the left and right side plates. I had no choice but to do it.

In addition, if a stopper to prevent the drawer from slipping forward or a roller to support the drawer is provided at the front end of the support rail, the left and right It was not possible to make the support rails on both sides a common shape, and the support rails were generally formed separately for the right and left sides of the drawer.
There was a problem that the manufacturing cost of parts increased.

The present invention aims to solve this conventional problem.

[Means to solve the problem]

In order to achieve this purpose, the present invention provides a cabinet in which a drawer is disposed within the main body of the cabinet made of a thin metal plate so as to be movable back and forth. A pair of left and right support rails for supporting the drawer rails protruding from both left and right sides of the drawer are fixed to the reinforcing frame at an appropriate distance from the front and back, and are vertically symmetrical and have a substantially U-shaped cross section;
Both support rails are bent in a vertically symmetrical manner so that their front end open parts widen vertically as they go forward, and the front end open parts of both support rails are attached to the front reinforcing frame. While the rear side surfaces are appropriately fixed to the rear reinforcing frame, the front reinforcing frame has a lower guide plate in front of the open front end portion of the support rail.
The structure includes a support rotating roller and a stopper for preventing the drawer from coming off at the front.

[Functions and effects of the idea]

According to this configuration, the front reinforcing frame and the rear reinforcing frame are fixed to the front and back positions inside the left and right side panels of the cabinet main body, and the support rails are arranged horizontally front and back across both the front and rear reinforcing frames, and welding, etc. Since the support rail is fixed to the reinforcing frame, the support rail can contribute to improving the strength and rigidity of the main body, and compared to the case where the support rail is detachably attached to the reinforcing frame, the strength and rigidity of the main body are significantly improved. It will improve.

The cross-sectional shape of the support rail is made into a vertically symmetrical shape with a substantially U-shaped cross section, and the support rail is bent vertically symmetrically so that its front end open part widens vertically as it goes forward. Since the stopper to prevent the drawer from coming off at the front and the support rotating roller are not attached to the support rail, they are attached to the front reinforcement frame.
This has the remarkable effect that the support rails on both the left and right sides can be made into the same shape, and the manufacturing cost of the main body of the cabinet can be significantly reduced.
