DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring duct device for a desk which can accommodate a wiring cord or the like of an electric device or the like placed on the desk in a vertical manner along a curtain plate.

[0002]

2. Description of the Related Art As a wiring duct device of this type, for example, Japanese Patent Application Laid-Open No. 2-177906 discloses a cover formed by forming a vertically extending concave groove at the rear of the inner surface of a side panel (side leg plate) of a desk. An invention is described in which the apparatus is detachably mounted, and a cord or the like is inserted into a concave groove from a wiring passage opening at a lower end of a cover so that it can be connected to an electric device on a top plate.

[0003]

This desk does not expose the cover and the like to the outside and does not impair the appearance of the desk. However, it is necessary to attach and detach the cover when wiring and removing the cord and the like. . However, since the cover is located at the back portion below the top plate, it is troublesome to attach and detach the cover, and when the cover is attached, the cover may be caught by the cords and may be difficult to attach. Also, if the cover is frequently attached and detached, the claws for locking the cover to the side panel may be worn, making it difficult to attach the cover.

Further, since a concave groove must be formed in the side panel, much labor is required, and the concave groove slightly reduces the strength of the side panel.

In the above-described wiring duct device, if a groove is provided in the sleeve box, the production of the sleeve box becomes more troublesome.

[0006] The present invention does not require the above-mentioned concave groove, the duct for passing the cords can be easily attached and detached, and the cord and the like can be easily taken in and out with the duct attached. It is another object of the present invention to provide a wiring duct device for a desk in which a duct can be easily attached to the inner surface of a sleeve box and the appearance of the desk is not impaired.

[0007]

The above object can be attained as follows. (1) At least one side edge of a curtain plate of a desk having a sleeve box or a side leg plate faces up and down, and the plan view is L in the forward and inward directions.
A flexible hard plate which is provided with a mounting plate which is bent in a letter shape and whose inner side surface is open, is provided forward, and between the curtain plate and the mounting plate, which faces in the up-down direction, has an E-shape in plan view and has an outer side surface opened. The rear piece and the center piece of the synthetic resin duct are detachably fitted to each other, and the side edge of the front piece is close to the inner surface of the sleeve box or the side leg plate.

(2) In the above item (1), the base of the front piece of the duct is formed of a flexible soft synthetic resin,
The base is elastically bent so that the front piece can be opened and closed.

(3) In the above item (1) or (2), the mounting plate or the curtain plate and the duct are elastically engaged with each other,
An elastic engagement means for preventing the duct from coming off is provided.

(4) In the above item (3), the elastic engaging means is provided on the locking piece bent backward from the inner end of the mounting piece and on the center piece of the duct. It is comprised with the engaging ridge which matches.

[0011]

According to the present invention, the duct can be easily attached to and detached from the mounting plate, and the wiring to the electric equipment on the desk is made by elastically bending the front piece of the duct attached to the mounting piece in advance to the end. It is sufficient to insert a cord or the like from between the edge and the side leg plate, or take out an unnecessary cord or the like, and it is not necessary to attach or detach the duct. Therefore, the wiring is extremely easy, and if the base of the front piece of the duct is made of a flexible soft synthetic resin as described in claim 2, it is easier to take in and out the cord and the like.

Since wiring can be provided between the rear piece and the center piece of the duct, wiring to a circuit which is easily affected by an external magnetic field or an electric field can be separately provided as necessary.

Since the duct can be easily attached to the side leg plate or sleeve box without special processing, the desk can be manufactured easily and inexpensively, and the duct can be formed at the inner rear end of the side leg plate or sleeve box. , So that the appearance of the desk is not impaired.

【The invention's effect】

(a) When wiring on a desk, the front piece of the duct previously attached to the mounting plate is elastically bent forward, and a cord or the like is put in and out of the gap formed between the edge and the side leg plate. Since there is no need to attach and detach the duct, the wiring on the desk is extremely easy despite the tight space.

(B) If the base of the duct is made of a flexible soft synthetic resin as in the second aspect, it is easier to put cords and the like in and out.

(C) Attaching and detaching of the duct is easy, and there is no need to attach or detach the duct when wiring, so that part of the duct is not damaged.

(D) If the duct is attached and detached, wiring can be made between the rear piece and the center piece of the duct. Therefore, wiring to a circuit which is easily affected by an external magnetic field or an electrostatic field can be performed separately. it can.

(E) The duct can be easily attached to each member other than the curtain plate without special processing, so that it can be easily attached to the inner surface of the sleeve box, and the desk can be easily and inexpensively manufactured. Can be manufactured.

(F) The duct can be attached to the side leg plate and the inside rear portion of the sleeve box, so that the appearance of the desk is not impaired.

(G) Providing the elastic engagement means as in claims 3 and 4 has the advantage that the duct itself is unlikely to come off the curtain plate or the like when the front piece of the duct is opened. In particular, claim 4
