Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] This invention relates to the structure of floor wiring.

[Background technology]

As shown in FIG. 1, an undercarpet wiring system consisting of a top protection sheet 1, a flat cable 2, etc. is laid directly on the floor and covered and hidden by a carpet 3. As the carpet 3, a rectangular floor-type carpet called a tile carpet is generally used. The floor outlet is attached to the flat cable 2 in the following manner. That is, as shown in FIG. 2, a part of the top protection sheet 1 is cut and removed, a terminal block 4 is electrically connected to the exposed flat cable 2, and a wiring opening 5 provided in the center of the bottom piece of the base 5 is opened. Position the terminal block 4 and fix the base 5 to the floor with the screws 6. Lay the carpet 3 on the floor so that the support 5b of the base 5 passes through the outlet mounting hole 3a of the carpet 3, and then attach the outlet main body 7. Screw holes 8 and 9 between the pillars 5b of the base 5
The outlet body 7 and the terminal block 4 are electrically connected to each other by a lead wire (not shown), the outlet body 7 is fitted into the notch 11a of the cover 11, and the cover 11 is inserted into the screw hole 12,
It is attached to the base 5 with screws 14 through 13.

However, since the outlet mounting hole 3a is formed by cutting and removing a part of the carpet 3, when the floor outlet is removed, the outlet mounting hole 3a remains at the removed position as shown in Fig. There was a problem in that the cable 2 was exposed and it was necessary to replace it with a new carpet.

[Purpose of the invention]

An object of this invention is to provide a floor wiring structure that allows continued use of the carpet even after the floor outlet is removed.

[Disclosure of the invention]

The structure of the floor wiring of this invention has a π
A shaped cut line is provided, and the tongue-shaped areas on both sides and the center surrounded by the π-shaped cut line are raised along three sides of the base other than the side where the outlet body is attached, and the cover is attached from above. After the floor outlet is removed, the tongue-shaped area is returned to its original position to close off the removal position.

An embodiment of the present invention will be explained using FIGS. 4 to 7. That is, the structure of this floor wiring is as shown in FIG. As shown in the figure and Fig. 6, the cover 18 is placed along the three sides of the base 17 other than the side where the outlet body is attached as shown in Fig.
is attached to the base 17.

To explain in detail, the flat cable 2 is formed by arranging band-shaped flat conductors 2a, 2b, and 2c in parallel at predetermined intervals and covering them with an insulating member 2d, and is laid on the floor.

The upper surface protection sheet 1 is laid so as to cover the upper surface of the flat cable 2, and is cut and removed only at the installation position of the floor outlet.

At this cut-off position of the top protection sheet 1, one end of each lead wire 19 is electrically connected to each conductor 2a, 2b, 2c of the flat cable 2 via a terminal block 20, respectively.

The base 17 has a wiring opening 17b in the center of the bottom piece 17a, supports 17c are erected at the four corners of the bottom piece 17a, and a connecting piece 17d is bridged between the upper ends of the supports 17c. In addition, each pillar 17
An engagement hole 17e is provided on the outer surface of the connecting piece 17.
A screw hole 17f is formed in d, and elongated screw holes 17g are bored on both sides of the bottom piece 17a. The base 17 is fixed to the floor with screws 21 with its bottom piece 17a placed across the flat cable 2 at the cut-off position of the top protection sheet 1.

The carpet 15 has a base 1 in an opening 15b (FIG. 6) formed by raising its tongue-shaped region 15a.
Lay it on the floor by inserting each support 17c of No. 7. In this case, each tongue-shaped region 15a is raised along three sides of the base 17 other than the side where the outlet main body is attached.

The outlet main body 22 has a pair of inverted L-shaped protrusions 22b protruding toward the back side on both sides of the plug insertion part 22a, and these inverted L-shaped protrusions 22b are connected to the engagement hole 17.
It is attached to the base 17 by inserting into and engaging with e. On the back side of this outlet main body 22, a connection terminal 19 provided at the other end of each lead wire 19 is provided.
a to electrically connect the ground terminal 22c and both power supply terminals 22d of the plug insertion portion 22a to the conductors 2b, 2a, 2c of the flat cable 2, respectively.

The cover 18 has a notch 18 extending upward from the lower end in one side piece 18a of the box body whose lower surface is open.
b, and a screw insertion hole 18d corresponding to the screw hole 17f of the base 17 is formed at the opposite corner of the upper piece 18c.
perforate. This cover 18 is attached to each support column 17 of the base 17 so as to cover each tongue-like region 15a.
c, and insert the plug insertion part 2 into the notch 18b.
2a, and screw the screw 23 through the screw insertion hole 18d into the screw hole 17f of the base 17 to fix it. In this state, the cover 18 covers the entire base 17 and covers the tongue-shaped region 15a and the lead wire 19.
is hidden.

In this way, the π-shaped cut line 16 is formed on the carpet 15.
Since the tongue-shaped region 15a is inserted between the three sides of the base 17 and the cover 18, even if the floor outlet is removed, the tongue-shaped region 15a can be simply returned to its original position as shown in FIG. The removed position can be closed off and the carpet 15 can be continued to be used.
In addition, since the tongue-shaped region 15a acts as a cushion material and absorbs impact force, the cover 18 is less likely to be deformed even if an external force such as a foot strain is applied to the cover 18.

〔Effect of the invention〕

According to the above-floor wiring structure of the present invention, the carpet can be continued to be used even after the floor outlet is removed.
