Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wiring device for neatly processing cords for office automation equipment, etc. used on an office desk.

[Conventional technology]

In recent years, so-called OA equipment such as office computers and word processors have become popular in order to improve the efficiency of office work.However, since many cords are connected to these OA equipment, it is difficult to place OA equipment on a desk. In some cases, there was a problem in that the cords hung around the desk, worsening its appearance and getting in the way of walking.

Therefore, it has been considered to form a storage area for cords on the back of the desk.
Japanese Utility Model Application Publication No. 56-158926 as a prior art discloses that a rear curtain plate that closes the back of the desk is detachably attached between the inner surface of the leg body and the inner surface of the sleeve cabinet. It is proposed that a locking member around which a cord is wound is fixed to the inner surface of the holder.

Also, U.S. patent no.
No. 3829187 discloses that a frame having a rectangular shape in front view is attached between the rear ends of the left and right legs of a desk so that the side surface of the frame is exposed to the side of the desk, and A device is disclosed in which a round hole or a square hole for passing a cord is formed on the left and right sides, and a rear curtain plate is attached to the rear surface of the frame to cover the rear surface of the frame. .

[The problem that the idea attempts to solve]

However, if the cord is attached to the inner surface of the rear curtain plate as in the former prior art of these two prior arts, the rear curtain plate cannot be removed or attached with the cord attached to the rear curtain plate. However, with this prior art, there is a problem that the work of attaching and detaching the rear curtain plate is extremely troublesome.
The rear curtain plate is attached between the inside surface of the legs and the inside surface of the cabinet, and the cords have to be inserted into and taken out from the inside of the desk from the bottom edge of the rear curtain plate, so they are lined up on the left and right. When drawing a cord into the inside of a desk that has been installed, the cord must be routed around the outside of the adjacent legs of the desks adjacent to the left and right before being drawn into the inside of each desk. There was also a problem in that the appearance deteriorated due to exposure to water.

On the other hand, in the case of the latter device described in the U.S. patent specification, the cord is stored inside the frame, so the rear curtain plate can be easily attached and detached. Since the cord can be pulled out to the side of the desk from the desk, it has the advantage that when the desks are installed side by side, the cord can be pulled directly into the inside of the left and right desks. The sides of the frame are exposed to the outside, which deteriorates the appearance.Furthermore, the cord must be passed through each round or square hole drilled in the side of the frame, making it difficult to insert the cord. There is a problem that is extremely troublesome.

Furthermore, in any of the above-mentioned prior arts, in order to pull out the cord onto the desk, the cord must be pulled out from the outside of the rear end of the top plate, so the rear end of the top plate must be brought into close contact with the wall of the room, or two desks must be connected to each other. Another problem was that it was not possible to arrange a desk with the rear end surfaces of the top plates in close contact with each other.

The present invention aims to solve these problems in the prior art.

[Means to solve the problem]

In order to achieve this object, the present invention provides a desk in which a top plate is supported by a pair of left and right legs, with the rear ends of the left and right legs being moved rearward by an appropriate dimension from the rear end surface of the top plate. A cord storage frame, which is approximately rectangular in front view and has at least the rear and upper surfaces open, is fixed between the inner surfaces of the rear ends of the left and right legs, and the left and right edges are attached to the rear of the frame. a rear curtain plate formed by bending the rear curtain plate such that bent pieces on both left and right edges of the rear curtain plate are in contact with the rear end surfaces of the left and right legs, and between the rear end surface of the top plate and the rear curtain plate; The cord is detachably attached to the rear panel so that a gap is left in which the cord can be freely pulled out, and cord insertion grooves communicating with the inside of the frame are formed in both bent pieces of the left and right side edges of the rear curtain plate. I made it.

[Functions and effects of the idea]

With this configuration, the top surface of the frame is open and there is a gap between the rear end surface of the top plate and the rear curtain plate that allows the cord to be pulled out freely, so that the cord can be stored inside the frame. The cord can be pulled directly upward from between the rear edge of the top plate and the rear curtain plate, so you can line up desks with their rear curtain plates close to each other, or place the rear curtain plate against the wall of the room. The cord can be pulled out onto the desk even when placed in close contact with the frame, and the frame is hidden between the left and right legs, leaving the rear curtain plate exposed to the outside. Therefore, the appearance does not deteriorate due to the provision of the frame.

The cord is inserted into and taken out from the cord insertion groove cut in the bent piece on the left and right side edges of the removable rear curtain plate.When desks are installed side by side on the left and right, the cord of the rear curtain plate for one person's desk is Since the insertion groove and the cord insertion groove of the rear curtain plate of the other desk face each other, is it possible to reliably prevent the cord from being exposed to the outside of the desk when inserting the cord inside the desks arranged side by side on the left and right? , or it can be reduced to the minimum necessary level.

Since the rear surface of the frame is open, it is possible to take the cord in and out of the frame by removing the rear curtain plate, but the cord insertion groove of the bent piece on the left and right side edges of the rear curtain plate is Because the cord is cut open, when inserting or removing the cord into the frame, there is no need to pass the cord through the cord insertion groove one by one. Since the curtain plate can be attached and detached, it is extremely easy to insert and remove the cord into and out of the frame.

Therefore, according to the present invention, it is extremely easy to insert and remove the cord into the frame, the cord can be pulled out onto the desk regardless of the installation state of the desk, and it also reliably prevents deterioration of the appearance. It has the effect that it can.
