Description

[Detailed description of the invention] [Field of industrial application] The present invention is to provide a cord storage body along the bottom surface of the top plate of a desk for storing cords for electrical equipment used on the desk. This invention relates to improvements to wiring devices.

[Conventional technology]

Japanese Utility Model Publication No. 60-34166 as prior art describes a wiring device for processing cords for electrical equipment used on the desk in an ordinary desk consisting of a single top plate fixed to the legs. A pocket drawer for storing cords with an upward opening is provided on the lower surface of the rear of the top plate so that it can be freely pulled out toward the rear of the desk, and a cutout groove for pulling out cords is formed in the rear panel of this pocket drawer. The configuration is described.

Also, Utility Model Application No. 58-114127 as other prior art
In the publication, the top plate of the desk is divided into front and back,
While the front top plate is fixed to the left and right legs, a left and right long cord storage body that opens upward is provided below the rear top plate, and on the rear edge of the cord storage body,
The rear top plate is pivoted via a hinge so that it can be flipped up and rotated toward the rear. In other words, the rear top plate is also used as a lid for the cord storage body. A device is described in which the opening of the wiring tray can be opened and closed.

[The problem that the idea aims to solve]

However, in the former configuration, in which the cord is taken in and out of the pocket drawer by pulling it out to the rear of the desk, the back of the desk is in contact with the wall of the building. When the cord is installed or two desks are placed back to back, the cord cannot be pulled in or out of the pocket drawer, making the desk inconvenient to use.

On the other hand, in the latter case, the cord can be inserted and removed from the top of the cord body, so it is possible to install the desk against the wall of the building, or to install two desks back to back. This has the advantage of not impairing the ability to take cords in and out of the cord storage body, but on the other hand, it is not possible to take cords in and out of the cord storage body without rotating the rear top plate. Each time the cord is inserted or removed from the body, the devices placed on the rear top plate must be removed and reinstalled one by one, which poses a problem in that wiring work is time-consuming.

This invention does not reduce the usability of the desk.
It is an object of the present invention to provide a wiring device that allows cords to be taken in and out of a cord storage body with extreme ease.

[Means to solve the problem]

To achieve this purpose, the present invention provides a desk with left and right legs and a top plate, in which the top plate is connected to a rear top plate that is fixed to the left and right legs, and a rear top plate that is movable in the front and back direction. The front top plate is divided into a front top plate, and a cord storage body with an upward opening is placed below the contact area between the rear top plate and the front top plate, and the opening of the cord storage body is connected to the front top plate. By moving back and forth to open and close the cord storage body, and by arranging the rear end edge of the cord storage body to be located below the rear top plate, the upper end of the rear edge of the cord storage body and the top plate can be opened and closed. It is configured to form a gap between it and the bottom surface through which the cord can be freely inserted.

[Functions and effects of the idea]

In this configuration, when the front top plate is moved toward the front of the desk, the top surface of the cord storage body opens, allowing you to insert and remove cords from above the desk and store cords inside the cord storage body. You can organize them so that they don't get tangled.

In that case, since the opening of the cord storage body is opened and closed by moving the front top plate back and forth, it is necessary to remove the equipment placed on the front and rear top plates one by one and reinstall them. Instead, wiring work can be done quickly while the equipment is placed on the front top plate.

In addition, a gap through which the cord can be freely inserted is formed between the upper end of the rear edge of the cord storage body and the bottom surface of the rear top plate, extending along the longitudinal direction of the cord storage body, so it can be used on a desk. Cords for electrical equipment, etc. that are used can be inserted into and taken out of the cord storage body from the rear side of the desk through this gap. Since the cord can be put in and taken out inside the cord storage body, heavy equipment is placed on the front top plate, or equipment is placed across the rear top plate and the front top plate. The cord can be reliably put in and taken out of the cord storage body even when the cord is placed in the cord storage body, and it is also possible to insert the cord into the cord storage body between two desks installed on the left and right or back to back. This can be done extremely easily.

Therefore, according to the present invention, since the cord can be put in and taken out from the inside of the cord storage body both from above and from the back side of the desk, the cord can be inserted and taken out from the inside of the cord storage body from both directions, such as from above the desk and from the rear side. Since you can select the insertion method for the cords, it is possible to wire the cords for electrical equipment used on the desk extremely easily without impairing the usability of the desk, and it is also possible to properly and neatly dispose the cords. It has an effect that can be done to.
