2. Description of the Related Art Conventionally, a floor formed by arranging a number of unit floor materials is provided on a building floor surface, and various types of so-called underfloor wiring spaces are formed between the lower surface of the unit floor material and the building floor surface. Various types have been developed in which the wirings can be inserted. Then, the wirings, which are led out from an appropriate part of the floor and started up, are guided to a desired position of furniture such as a desk.

[0003]

However, if the wirings are simply erected from the floor, they tend to be unsightly and cluttered around furniture such as desks, and they become entangled with each other and cannot be removed. Easy to fall. There are also cases where a wiring duct is built into the desk and the wiring that is erected from the floor is guided to this wiring duct, but this makes the structure of the desk itself complicated, and in the case of an existing desk, In addition to not being able to realize the mode, if the desk is inadvertently moved when the layout of the office is changed, the wirings are forcibly pulled, which causes disconnection.

In order to eliminate such inconvenience, recently, there has been considered a wiring guide dedicated furniture for wiring arrangement which can be used by being attached to furniture such as a desk. This is a structure in which a pipe frame is combined to form a gate-shaped structure composed of left and right legs and a connecting portion for connecting the legs, and a wiring duct is installed between the left and right legs. However, this wiring guide furniture is merely intended to form a wiring duct that accommodates wirings between legs. For this reason, there is a drawback that the wirings are exposed before the wirings that are erected from the floor are guided to the wiring duct, and many pipe frames are used to form a structure including legs and connecting portions. Since it has to be constructed and an end plate is also required at a position for closing the pipe frames on the outer end face of the leg, there is a problem that the overall cost cannot be effectively reduced.

[0005]

In order to solve the above problems, the present invention provides a wiring accommodating function to the structural elements of the structure itself, thereby making it possible to suitably route the wiring with a simple structure. The purpose is to provide such furniture for wiring guidance.

Form a ridge extending parallel to the side wall, and between the side walls or side
It is characterized in that the space between the wall and the ridge is a lateral wiring space .

With such a construction, the wirings led out on the floor are first guided to the vertical wiring space of the legs, and then, if necessary, drawn into the horizontal wiring space of the trough, It can be led out to the outside through an opening provided in a part of these wiring spaces. The vertical wiring space is inside the leg body, and the lateral wiring space is also hidden from the outside by the exterior plate. For this reason, it is possible to effectively guide the wirings, which are erected from the floor, to a desired place such as a desk with the blindfolded state. Moreover, the leg and the trough-shaped member are not only structural members of the structure but also doubled as components of each wiring space, and it is not necessary to dispose the end plate on the outer end surface of the leg. , This one is basically a leg,
It can be composed of three members, a trough-shaped member and an exterior plate, and the number of parts and the number of assembling steps can be greatly reduced.

As a concrete mounting structure of the trough-shaped member, the leg body has an open groove extending vertically on the inner end surface, and vertical walls that are parallel to each other are integrally formed on both opening edges of the open groove. And the outer surfaces of both side walls of the trough-shaped member are in close contact with the opposing surfaces of these vertical walls to be rigidly connected. Preferred modes of the openings include an upward opening formed between the upper ends of the legs and a lateral opening formed on the outer end surfaces of both legs.

In order to effectively use the space between the legs in which the trough-like member is not disposed, a fixed mounting end face for detachably mounting the shelf is formed inside the legs. Is effective. Even if the legs are used like this,
In order to effectively carry out wiring change work etc. for the wiring accommodated in the vertical wiring space of the legs, an opening window for opening the vertical wiring space is provided on the outer end faces of both legs. ,
It is desirable that a cover is detachably attached to the opening window.
