DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base and a lid fitted to each other and wiring and wiring in a housing space formed therebetween.
The present invention relates to a protective cover for wiring and piping material in which piping material is stored and protected.

[0002]

2. Description of the Related Art A conventional protective cover for accommodating and protecting wiring and piping materials is composed of a base and a lid which are assembled in a mutually fitted state. In a normal design, no gap was provided in the assembly direction with the body.

[0003] Although the fitting force of the base and the lid is increased by the above-mentioned fitting structure, it may be necessary to remove the lid from the base for repair and inspection after construction.
In this case, it is not easy to remove the lid from the base because the lid is firmly fitted to the base so as to be immovable in all directions. In particular, when the protective cover is small, it is difficult to insert a small tool into the contact portion between the base and the lid and to pry it, so that the removal is more difficult.

That is, in a protective cover in which a base and a lid are fitted together, it becomes more difficult to remove the lid from the base as the fitting force between them increases, and the fitting force increases. Doing so and facilitating the removal of the lid from the base are mutually contradictory matters.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a protective cover for a wiring / pipe material in which a base and a lid are fitted to each other, while maintaining a fitting force required for fitting the two.
It is an object of the present invention to facilitate release of fitting between a base and a lid.

[0006]

According to a first aspect of the present invention, a base and a lid are fitted together and integrally assembled to house and protect wiring and piping materials therein. A protective cover for wiring and piping material, wherein the base and the lid are assembled so that, in a state where the two are fitted, a gap serving as a removal allowance for releasing the fitting faces the outside. Is its characteristic. Claim 2
Is a similar wiring and piping material protective cover,
The fitting between the base and the lid is a first fitting in which the two are relatively separated from each other so that a gap serving as a removal allowance for releasing the fitting between the base and the lid is exposed to the outside. It is assembled so as to be slidable along the assembling direction between a mating state and a second fitting state in which the two fit relatively close to each other so as to eliminate the gap. Is its characteristic. In any of the first and second aspects of the present invention, the base and the lid have a necessary assembling force by fitting each other, and release the fitting in the fitted state. When a tool such as a screwdriver is inserted into the gap and turned, an excessive force acts on the lid, and the fitting is easily performed. It is released.

[0007] The invention according to claim 3 is the invention according to claim 1 or 2.
The base and the lid are formed so as to be fitted to each other by an engagement between an engaging portion formed on the lid and an engaged portion formed on the base. Since the joint portion is disposed inside the engaged portion, when an external force acts on the protective cover from above or from the side, and both the base and the lid are deformed, The deformation acts in a direction that further ensures the engagement between the engaging portion and the engaged portion.
Therefore, even when an external force acts on the protective cover in use, the lid is not removed from the base.

According to a fourth aspect of the present invention, based on the first and second aspects of the present invention, the base and the lid are provided with an engaging portion formed on the lid and an engaged portion formed on the base. The engagement portion is formed so as to be fitted with each other, and the engagement portion is arranged outside the engaged portion. Is played.

According to a fifth aspect of the present invention, based on any one of the first to fourth aspects of the present invention, the cover is directed to a fixing surface to which the base is fixed so as to cover the side of the base. A gap that serves as a removal allowance for releasing the fitting between the base and the lid is formed between the extended end of the side wall and the fixing surface. Therefore, even in a protective cover in which the base side is covered by the lid, a gap serving as a removal allowance for releasing the fitting between the base and the lid can be formed in a state facing the outside. Therefore, it is easy to release the fitting between the base and the lid, and the fitting portion is covered by the lid,
Aesthetics increase.

According to a sixth aspect of the present invention, on the premise of the first to fifth aspects, the clearance serving as a removal allowance is obtained by rotating a tool such as a screwdriver inserted therein.
Since it functions so as to release the engagement between the two, the release operation of the base and the lid is facilitated.

Further, according to a seventh aspect of the present invention, based on the first to sixth aspects of the present invention, the base and the lid are fitted to each other to accommodate the wiring and piping material formed at the end thereof. The opening of the space is characterized in that it has such a size that a human finger cannot be inserted. The protective cover according to the invention of claim 7 is small, and it is more difficult to remove the lid from the base, but such a small protective cover faces the outside of the protective cover and is a removal allowance. Since the gap is formed, the fitting between the base and the lid can be easily released by inserting and prying small tools into the gap. In addition, the protective cover before the construction is generally such that the base and the lid are fitted together. In the construction, when the fingertip is inserted into the opening and lifted, the base is applied with a relatively small force. And the lid are sequentially separated in the longitudinal direction.
