Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a desk wiring structure that is preferably used in an office or the like.

[Prior Art] Conventionally, when a device is placed on a tabletop of a desk, its wiring is raised from the floor so as to be guided to the device.

[Problems to be solved by the invention] However, in such a case, it is inevitable to guide the wirings raised from the floor to the equipments on the top plate without any guidance. Therefore, the wirings may become messed up, and the appearance may be impaired, or the wires may be caught and cut.

In order to eliminate such a problem, a wiring insertion port is provided at the corner of the top plate, and the wiring insertion port is formed by a cylindrical seat so that the lid can be attached to and detached from the upper end opening of the wiring insertion port. It is possible to put it on. in this case,
A step portion is formed on the inner circumference of the seat, and the lid body is provided with a plurality of wall pieces forming a cylindrical wall and a projecting ridge protruding outward at the tip of the wall piece. Then, if it is such a thing, when wiring is not required, a lid is attached to the wiring insertion port and the brim is hooked on the step portion of the seat, and if necessary, the above-mentioned Wiring is possible by removing the lid.

However, in such a structure, the wall piece of the lid body is curved inward, and the flange at the tip also functions as a rib. Therefore, when the lid is removed, even if an upward pulling force is applied to the lid, the wall piece is unlikely to be elastically deformed inward, and the lid may not be easily removed.

The present invention aims to solve such problems.

[Means for Solving the Problem] The present invention has taken the following means in order to achieve the above-mentioned object.

That is, the wiring structure of the desk according to the present invention comprises a wiring insertion opening provided at a corner portion of a top plate, a seat forming the wiring insertion opening, and a lid detachably attached to an upper end opening of the wiring insertion opening. The seat has a step on the inner circumference, and the lid has a plurality of wall pieces forming a cylindrical wall. A protrusion protruding outward is provided at a corner of the tip, and the protrusion of the lid is hooked on the step of the seat. Then, in order to make it easier to remove the lid and to make the wiring insertion hole inconspicuous in the wiring state, the seat has a recessed portion continuous to the wiring insertion opening at the upper end, and the lid is attached to a part of the wall. It is characterized in that it has a notch and is rotatably attached to the upper end opening of the wiring insertion opening.

[Operation] With such a configuration, it is possible to guide the wirings on the floor onto the top plate through the wiring insertion openings provided at the corners of the top plate. When the wires are not inserted, the wire insertion port may be closed with a lid, and the appearance is not damaged.

Further, the corner portion at the tip of the wall piece of the lid can be elastically deformed inward relatively easily. Therefore, when the lid body is pulled up when removing the lid body, the corner portion is elastically deformed, and the engagement state between the projection of the wall piece and the step portion of the seat is released.

Further, when the diameter of the wirings is relatively small, the lid can be attached even in the wiring state. That is, when wiring is performed with the lid attached, if the lid is rotated so that the notch and the recess of the seat are located in the same direction,
Wirings can be guided onto the top plate through the notches and the recesses. Further, the wirings may be passed through the recess in advance, and the lid may be attached so that the notch and the recess are aligned. By doing so, the wiring insertion port can be made inconspicuous even in the wiring state, and the appearance can be improved.
