Description

[Detailed Description of the Invention] Industrial Application Field The present application relates to an office cabinet used on a tabletop or the like for storing and organizing documents, etc.

Conventional technology In the past, simple office cabinets used on tabletops, etc., were made from synthetic resin with multiple rail pieces extending in the front and back direction and spaced apart in the height direction on the left and right inner surfaces of a hollow case with an open front. There is a well-known office cabinet in which plate-shaped shelf members are mounted and faced to each other, and a drawer made of synthetic resin can be pulled out between the opposing left and right rail pieces. , to prevent the drawer from coming off the rail when you pull it out toward you.
The front part of the rail piece is made wider than the middle part, and a step part for a stopper is provided on the inner edge side, and a locking protrusion that locks to the step part is provided protrudingly at the rear position of the bottom surface of the drawer. It is structured as follows.

Problems to be Solved by the Invention However, according to the conventional cabinet described above, when the drawer is removed from the rail piece and used by placing it on the top of the desk, the drawer is protruded from the rear of the bottom of the drawer. There is a risk that the locking protrusion may damage the desk top, and since the front part of the rail piece is made wide in order to provide a step for the stopper, the inner edge of the rail piece may be damaged by the load of the drawer. It tends to deform downward due to the collision with the locking protrusion, and there is a risk that the locking protrusion will not reliably lock with the stopper step when the drawer is pulled out. In order to avoid this fear, when the height of the locking protrusion was increased, the problem was that the locking protrusion became a nuisance.

Therefore, the purpose of the present application is to eliminate the deficiencies of the conventional devices described above.

Means for Solving the Problems In order to achieve the above object, the present application provides a composite structure in which a plurality of rail pieces are provided on the left and right inner surfaces of a hollow casing having an open front and extending in the front and back direction and spaced apart in the height direction. Platy-shaped shelf members made of resin are attached to each and face each other,
In addition, in an office cabinet in which a drawer made of synthetic resin is extendably extended between opposing rail pieces on the left and right sides, a drawer made of synthetic resin is protruded upward from the front part of the rail piece at a required distance from the inner surface of the shelf member. A stopper is provided, and sliding contact ridges are provided on the bottom surface of the drawer along the left and right edges of the drawer to make sliding contact with the top surface of the base of the rail piece. The present invention is characterized in that a locking protrusion that protrudes within the height range of the protrusion and locks with the stopper is provided.

Function: The sliding protrusion intervenes between the inner surface of the shelf member and the front stopper on the lower surface of the drawer that is suspended between the opposing rail pieces of the shelf member, and when the drawer is pulled out in this state, , when the sliding protrusion is guided by the inner surface of the shelf member and the front stopper and slides on the upper surface of the base of the rail piece, and when the drawer is pulled out, the drawer engages with the front stopper of the rail piece. The stop protrusion comes into contact with the drawer and can protrude about 2/3 forward.
