Description

[Detailed explanation of the invention] A. Purpose of the invention [Industrial field of application] This invention is designed to provide cables that pass through the floor finishing material and run cables above the floor in computer rooms, office automation equipment rooms, etc. where wiring is installed under the floor. The present invention relates to a cover that is attached to the cable lead-out part of the floor finishing material to improve the appearance of the part when the cable is pulled out.

[Conventional technology]

In floor wiring equipment, in order to prevent cables that pass through the floor finishing material and are pulled out onto the floor from touching and damaging the edges of the cable exit hole in the floor finishing material, a rubber bushing should be fitted to the edge of the hole. There is.

[Problem that the invention attempts to solve]

The rubber bushing fitted into the cable lead-out hole above is
The edges of the rubber are exposed on the surface of the floor covering material, making it unsightly.

And if the floor finishing material is carpet tile,
Insert the rubber button into the cable outlet hole.
Due to the elastic compressive force of the rubber or the bending of the cable inserted through the hole, the area around the edge of the hole in the carpet tile may become erect or warp, impairing its appearance.

The object of the present invention is to solve the above-mentioned problem regarding the cable lead-out hole in a floor wiring device in which carpet tiles are used as a floor finishing material.

B. Structure of the invention [Means for solving the problem] The present invention provides a cover for the cable lead-out part that achieves the above object, and is large enough to cover the cable lead-out hole drilled in the carpet tile of the floor. It consists of a cover body that can be divided into two along a line that crosses the cable insertion hole in the center, and a protruding part whose lower surface touches the floor carpet tile is provided along the outer periphery of the cover body. The gist is that a male piece of hook-and-loop fastener is attached to the bottom surface of the exit part.

[Effect]

Connect the split cover body to the cable coming out of the cable outlet hole of the carpet tile by fitting the split cover body from the left and right so that the cable enters the central cable insertion hole, and connect the integrated cover body along the cable. It is moved to the top of the lead-out part and pressed against the carpet tile, and the cable lead-out part is covered by the cover body, and the cover body is
It is fixed by engaging the male piece of the surface fastener to the carpet tile.

〔Example〕

FIG. 1 is a perspective view showing the cable outlet cover of the present invention in use, and FIG. 2 is an enlarged perspective view of the main parts thereof.

Square unit panel 1 with a side of e.g. 600mm
Two orthogonal protruding wiring grooves 2 are provided on the upper surface of the wiring groove 2 .

The unit panel 1 consists of a large number of small rectangular blocks 1A made of lightweight concrete with a minute space between them.
Further, at the position of the wiring groove 2, a series of flexible sheets 3 (shown in the third figure) are arranged vertically and horizontally at intervals corresponding to the grooves, and on the top and side surfaces of the small blocks 1A and the bottom of the wiring groove 2. ) is used to connect small blocks to each other.The unit panel 1 is flexible and is laid to follow the unevenness of the floor.

In addition, the unit panel 1 may be constructed of a rigid plate made of an aluminum die-cast plate, a laminated asbestos plate, a particle plate, a concrete plate, a gypsum board, a reinforced plastic plate, or any combination thereof.

The bulge-shaped wiring groove 2 is covered with four cross-shaped cover plates 4 of the same shape and size, which are fitted into a stepped portion 5 (shown in the third figure) formed at the opening edge of the groove 2 to form a cross-shaped cover plate. The top surface of the cover plate 4 is the unit panel 1.
It is configured to match the top surface of the That is, the height of the stepped portion 5 and the thickness of the cover plate 4 are made equal.

The material of the cross-shaped cover 4 is arbitrary, such as a hard plastic plate, an aluminum plate, or a steel plate.
If necessary, the front and back surfaces of the cover plate 4 may be coated with soft plastic or electrostatically flocked to provide cushioning properties.

By laying the above unit panels 1 side by side on the floor, the orthogonal line grooves 2 of each unit panel 1 can be
A lattice-like wiring groove is formed one after another on the entire floor.

Power lines, telephone lines, information lines C, etc. are placed separately in the continuous wiring groove, the wiring groove is covered with a cross-shaped cover plate 4, and the position where the cable is pulled out is placed.
A cross-shaped cover plate 4, which has a lead-out hole 6 in advance, is fitted.

After the laying is completed, a carpet tile 7 is placed on each unit panel 1 with the wiring groove 2 covered with a cross-shaped cover plate 4. At the wiring lead-out position, a hole 8 is made in the carpet tile 7 in line with the cable lead-out hole 6 of the cover plate 4.

The cable outlet hole 8 of the carpet tile 7 is covered with the cable outlet cover of the present invention.

The cable outlet cover consists of a cover body 9 molded of synthetic resin or metal into a medium-height shape such as a sunken bowl, sunken bowl, or kasa-shape, and has a cable insertion hole 10 in the center of the top.

The cover main body 9 has a diameter that covers the cable lead-out hole 8 opened in the carpet tile 7, and is split into two from a diametrical line passing through the center of the central cable insertion hole 10.

The divided left and right cover halves 9A and 9B can be easily handled if one end is connected by a hinge portion 11 as shown in FIG. When the cover main body 9 is molded from a synthetic resin such as polypropylene or polyethylene, the hinge portion 11 can be molded integrally with the main body 9 at the same time.

As shown in FIG. 4, the abutting portions of the cover halves 9A and 9B are provided with positioning small uneven portions 12A and 12B that engage with each other.

A male piece (claw-shaped) of a hook and loop fastener 14 is attached to the lower surface of a projecting portion 13 that is formed outwardly in the shape of a flange along the outer peripheral edge of the cover body 9.

Note that the projecting portion 13 may be formed inward along the outer peripheral edge of the cover main body 9 as shown in FIG. 5.

When the cover body 9 is fitted onto the cable C and pressed against the surface of the carpet tile, the male piece 14 of the hook-and-loop fastener on the lower surface of the overhang 13 will be caught on the loop or fluff on the surface of the carpet tile 7. It is something that multiplies.

C. Effects of the invention Since the cable outlet cover of the invention has the above structure, it can be easily attached to a cable pulled out onto the floor through a carpet tile, and can be attached by simply pressing it onto the carpet tile. It can be mounted securely. Furthermore, when changing or inspecting wiring, the cable can be easily removed from the carpet tile by pulling, which has the effect of improving the appearance of the cable lead-out portion.
