Description of the Related Art Recently, a wiring cable such as a power cord extending from an electric device or the like placed on a desk or an extension cord connected to the power cord is provided on a desk from the viewpoint of appearance and appearance. They are not exposed to the outside through the duct.

In most conventional wiring duct structures, the opening surface of the duct into which a cable or the like is inserted is limited to either the front or back of the desk, and the insertion opening is always open. How was it?

[0004]

Therefore, the wiring work for the cables and the like has to be carried out by moving to either the front or rear duct surface, and the workability is poor. Further, if the opening of the duct is always open, the cable or the like wired or housed in the duct is not only easily protruded by an external force but also exposed from the outside, which is not preferable in terms of appearance.

The present invention has been made in order to solve the above-mentioned problems, and the wiring of cables and the like and the storage work are
It is an object of the present invention to provide a wiring duct structure for a desk or the like that can be carried from both front and rear sides of the desk or the like, and can securely and cleanly store and conceal cables and the like.

[0006]

In order to achieve the above-mentioned object, the present invention provides a locking piece on the upper surface of a front end portion of a support substrate having a hinge portion which is vertically bendable near the rear end portion.
In addition, the rear end of the duct unit in which the closing pieces elastically deformable in the front-rear direction are erected upwardly at the rear end is spaced apart from the lower surface of the rear end of the top plate by a required dimension. It is fixed to the upper end of the provided curtain plate so that the upper end of the closing piece and the lower surface of the top plate abut or come close to each other, and the locking piece is detachably engaged with the reinforcing member below the top plate. It is characterized by having done.

[0007]

When the closing piece located between the top plate and the curtain plate is elastically deformed forward, the cables and the like can be stored and concealed in a duct below the top plate from the rear of the desk or the like in a good appearance. Also, if the engaging piece on the upper surface of the front end of the support substrate is disengaged from the reinforcing member below the top plate, the support substrate pivots and tilts downward around the hinge portion, so that cables, etc. It can be easily stored in the duct from the front.
