Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device in a wiring floor in a double floor for wiring, which is installed from the upper portion of the wiring path to serve as a lid for the wiring path and provided with electrical wiring components such as outlets. Is.

[0002]

2. Description of the Related Art At present, double floor systems for floor wiring are widely known for OA floors. In particular, as a double-floor structure of this type, for example, a plurality of wiring paths are formed in a floor mat with concave grooves, a large number of wirings are laid here, and a step portion is provided in the concave groove portion. A grooved wiring system is used that includes a wiring path cover that is placed on a stepped-down portion and covers the wiring path.

In this type of groove wiring system, an electric wiring component such as an outlet is embedded in a part of the floor mat, which is cut out, or in the wiring path, so that it can be easily installed in any place where an outlet is required. It has the feature that wiring can be relocated and expanded.

In recent years, a technique has been known in which an electric wiring component such as an outlet is integrally provided on the wiring path cover as described above (Japanese Patent Laid-Open No. 5-153714). This is a part of the rear side of the cover plate of the wiring path cover that covers the wiring groove of the grooved wiring type, and has a structure in which electrical wiring components such as an outlet whose planar shape is almost the same as that of the cover plate are provided. By utilizing the installation portion of the board, the electric wiring component can be easily arranged only in the wiring path without cutting off a part of the floor mat.

Specifically, a lid plate is arranged so as to close the upper opening of the wiring groove, and the planar shape of the lid plate is formed in almost the same shape in place of the lid plate in a part of the installation portion of the lid plate. It is a structure with electrical parts, and outlets for electrical wiring parts are
It has a structure that opens to the upper surface of the lid plate.

[0006] With this configuration, since the electrical component uses the installation portion of the cover plate, it can be arranged at the construction site without cutting off a part of the floor base material. No tools or the like for cutting out the floor material are required, and it is not necessary to process a part of the floor base material to be cut off.

[0007]

However, the above-described structure in which a device such as an outlet is integrally provided on the wiring path cover has the following drawbacks.

(1) Since the groove cover plate is simply replaced with the original groove cover plate and the groove cover plate is placed in the stepped recess, it cannot be securely fixed. That is, although it can be easily replaced, it cannot be reliably fixed because of the structure and method in which it is forcibly restrained from the top by the finishing material only by mounting it, resulting in misalignment and pedestrian noise.

(2) Since the electrical parts are opened above the floor and the cables are connected from the floor, the electrical parts are exposed on the upper surface of the cover plate. Therefore, it is necessary to make a hole for the opening, which is troublesome. In addition, a level difference corresponding to the thickness of the finishing material is generated, and the flatness of the walking surface is impaired. To solve this problem, for example, as shown in FIG. 11 of Japanese Patent Laid-Open No. 5-153714, it is possible to further attach a lid such as a finishing material, but this will deteriorate usability.

(3) The connection between the wiring device and the wiring cable is within the wiring path and covered by the wiring path cover, so it is preferable to be able to confirm the disconnection of the cable connection or the like. However, since no measures have been taken to prevent the cable connection from coming off, it is not easy to confirm whether or not the cable has been reliably connected. In addition, this kind of cable retaining structure is
As a unitary structure, for example, it is disclosed in Japanese Utility Model Application Laid-Open No. 64-2519. However, this is a structure in which the retaining portion and the wiring device are separate bodies, and thus the operability and the assemblability are poor. For this reason, in the cable retaining structure, a structure that has good operability and can be easily attached and detached and assembled has been required.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to securely and easily fix it in a wiring path without causing a positional displacement, a stepping noise, etc. (EN) Provided is a structure of a wiring device having electric wiring parts that can be easily installed and removed, which is easy to move and add wiring devices while maintaining flatness, and has good operability. .
