Description

[Detailed description of the invention] [Field of industrial application] This invention is designed to prevent wiring cords for these electrical appliances from interfering with each other when electrical appliances such as lighting fixtures and telephones are installed on the top of a study desk or office desk. This invention relates to the structure of a leg device for a desk that allows easy wiring without having to do anything.

[Prior art] As seen in the prior art Japanese Utility Model Application Publication No. 49-4804, the legs of a desk are formed into a hollow shape, and wiring cords are inserted vertically into the hollows, and the lower ends of the legs are A configuration in which a wiring terminal plug is provided near the part is disclosed.

[Problem that the invention attempts to solve]

However, in the prior art, the upper and lower longitudinal sides of the legs are closed. Therefore, before attaching the desk top and legs, it is necessary to insert the wiring cord inside the legs and connect the cords to the wiring terminal plugs. It was almost impossible to add or change cords, such as wiring along the inside of the cord.

Furthermore, no measures have been taken to deal with problems such as power lines and telephone lines, which can cause electrical interference when the two lines come close enough to touch each other.

The present invention aims to solve the above-mentioned conventional problems.

[Means for solving problems]

Therefore, in the present invention, the legs that support the desk top are formed into a hollow shape with longitudinal openings along one side of the upper and lower longitudinal sides, and the upper and lower longitudinal partition plates are provided along the inside of the hollow parts of the legs. A rear wiring space that is not open to the longitudinal opening side and the wiring space that is open to the longitudinal opening side are formed, and the front wiring space is closed in the longitudinal opening. A top and bottom longitudinal cover body is provided removably, while a corner plate is fixed to the leg near the bottom end of the longitudinal opening adjacent to the bottom end of the cover body, and a wiring terminal plug is provided on the corner plate, The cord outlet on the rear surface of the wiring terminal plug is configured to face the inner wiring space.

[Action/Effect]

According to this configuration, the inside of the hollow leg having a longitudinal opening on one side is divided into two wiring spaces by the upper and lower longitudinal partition plates, so that the wiring cords can be inserted into the two wiring spaces independently and interfere with each other. It can be inserted without being damaged.

These two wiring spaces are separated into a front wiring space that is open to the longitudinal opening, and a back wiring space that is further back than that and is not directly open to the longitudinal opening. In addition, the cord outlet on the rear side of the wiring terminal plug attached to the corner plate near the lower end of the leg faces the back side wiring space, so it can be pre-wired like a power wiring cord. A cord can be inserted into the wiring space on the back side, and its end can be connected to the cord outlet on the rear side of the wiring terminal plug attached to the corner plate.
For items such as telephone wiring cords that need to be added or abolished freely, the wiring space on the front side can be used to easily install wiring by attaching and removing the cover body.

Furthermore, since the corner plate is fixed to the lower end of the longitudinal opening of the leg, deformation of the leg that would cause the opening to open can be easily prevented, and the strength and rigidity of the leg can be increased. This simultaneously serves as a leg reinforcing member and a wiring terminal plug mounting member, and has the effect of simplifying the structure of the leg.
