Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to the structure of a rear curtain plate in an office desk.

[Background of the idea]

In recent years, with the advancement of office automation, computers, word processors, and other so-called OA equipment are increasingly placed on desks. As devices are connected, cords and intermediate devices protrude outside the desk, resulting in poor appearance and increasing problems such as people tripping over cords that are dripping onto the floor.

[Conventional technology]

Incidentally, there have been various attempts to store cords for telephones and other electrical devices used on the desk in the back of the desk. For example, in Japanese Utility Model Application Publication No. 56-158926, a frame having a rectangular shape when viewed from the front is detachably attached to the back opening of a desk, a curtain plate is fixed to the back of the frame, and the inner surface of the curtain plate is attached to the back of the desk. A device has been disclosed in which a cord hanger and a connector holder are firmly fixed.

Furthermore, in Japanese Utility Model Application Publication No. 57-124127, by disposing an inner surface plate along the inner surface of the rear curtain plate of the desk,
A hollow part for storing the cord is formed at the rear of the desk, and a cord locking tool is fixed to the inner surface of the rear curtain plate.
A device has been disclosed in which the inner surface plate can be opened and closed by facing the front of the desk.

[Problem that the invention attempts to solve]

However, in all of the above-mentioned prior art, the cord retainer and the connector receiver are fixed to the inner surface of the rear curtain plate, so when storing the cord etc., the rear curtain plate must be placed on the desk in advance. After fixing the cables to the desk, the worker had to crawl inside the desk and gather the cords together to store them, making the task of storing the cords and the like troublesome. In addition, since cord anchors, connector holders, etc. are fixed to the wide rear curtain plate, if a large number of cord anchors and connector holders are installed, the rear curtain plate will be affected by the weight of the stored items. There was also a problem in that the amount of storage for cords, intermediate equipment, etc. was limited due to bending and deformation.

The present invention does not cause such problems,
A storage section for cords, etc. can be formed on the back side of the desk.

[Means for solving problems]

In order to achieve this purpose, in the present invention, a rear curtain plate placed on the back side of the desk is attached to and detachable from a frame body which is rectangular in front view and is made up of horizontal beam members connected above and below the left and right column members, and from the back side of the frame body.
