Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a carpet/nod in which electric wires are buried, and a wiring system using this carpet. Recently, OA
With the spread of devices, each desk in a typical office now has a telephone, a computer terminal, a word processor, and a personal computer. By the way, desk positions in offices often change due to organizational changes or the assignment of new employees. Wiring changes (2) must be made each time, but since the floor is carpeted, the carpet has to be moved each time, which takes time for wiring work, which limits the ability to change the layout. Sometimes it appeared. Furthermore, having electric wires rolled on the carpet surface spoils the aesthetics of the interior and is not desirable from the standpoint of safety.

The present invention provides a new carpet with buried electric wires that has improved the above-mentioned drawbacks, and a wiring system using the carpet.

The present invention will be described in detail below based on one embodiment thereof.

In the figure, 1 is a carpet, which has a fiber layer 2, an elastic electrical insulating material layer 3, and a thin sheet-like electric wire 6 in which a flat conductor 4.4 is covered with rubber 5 is embedded in the electrical insulating material layer 3. It is something. If the electrically insulating material layer 3 has sufficient safety (strength, electrical resistance, heat resistance), the conductors 4, 4 may be directly embedded in the electrically insulating material layer 3. Reference numeral 7 denotes a display section in which the color and pattern (3) for indicating the device in which the electric wire 6 is buried are different from those of the other portions of the fiber layer. At the same time, this display also serves as an accent pattern on the carpet. In addition, if the flat buried conductor is buried separately not only for commercial power supply but also for electric signals, this display section 7
also be displayed so that they can be distinguished. Reference numeral 8 denotes a plug connected to the end of the buried electric wire as an end connector of the carpet, and connecting pins 14a, 14a are provided on the underside of the connector 8'' shown in FIGS. 8 to 9. The terminal plate 14b is made to protrude and connected to the connecting pins 14a, 14a.

14b, and connect the plug L to this terminal board 14b, 14b.
A connector 8' may be used to which the electric wire 14d connected to the electric wire 4c is connected. Suitable when the carpet is not a standard size.

Such a wiring system using a carpet with buried electric wires can be used, for example, when connecting electrical equipment such as a load or a signal transmitter in a room with a pet as shown in Figures 2 to 5. As shown in the figure, (4) In particular, in the case of a signal transmitter, electrical signals may be transmitted by electromagnetic inductive coupling.

First, referring to FIGS. 2 to 4, reference numeral 9 denotes an electrical connector, which includes a base 10, a lid 11, a blade holder spring 13 housed in a recess 12 provided in the base 10, and this blade holder spring. 13 and the connecting pin 14 electrically coupled to the connector 9
and a tapping screw 15.15 for bonding the electric wire 6 to the insulating material layer in which it is embedded.

The connecting pins 14, 14 are embedded and fixed by simultaneously molding the heads 16 on the base 10. Note that 17 is a terminal portion, and has a cover 18. 19 is a cover made of the same material as the carpet or a similar material.

20 is a screw for connecting this cover to the connector 9. It is preferable that the plug blade inlet 21° 21 of the connector 9 be provided on the side (see FIG. 5). Then, the display part 7 of the carpet 1 is cut open as shown in FIG. 2 to expose the insulating material layer 3.
4.14 and connect it to the conductor plate 4.4, and by screwing in the tapping screw 15° (5) 15, the insulating material layer 3 is drawn toward the connector 9 side, and the connecting pin 14.14 and the flat conductor plate are connected. 4. Assume that the connection in 4 is confirmed.

The cover 19 is designed to cover the connector 9.

Next, in the case shown in FIG. 6, an electrical signal is transferred from the surface of the carpet 1 by electromagnetic induction without making a direct electrical connection.

A magnetic material 23 is placed on the electric wire 6 buried in the carpet 1. 23 is a coil, and 24 is an electric wire connected to this coil.

25 is a cover. Therefore, by intermittently passing a pulsed current through the coil 23, the signal 26 can be superimposed on the commercial power source as shown in FIG. This superimposed electrical signal 26 may vary depending on its position and number.
This electrical signal can be given a specific meaning, received by a receiver installed in another room, and used to control the load using the receiver's output.

The explanation so far has been about the connection between electric wires buried in the carpet and (6) electrical equipment such as loads and signal transmitters placed on desks. Next, a method for connecting the electric wire 6 buried in the carpet to a power source or to an electric device installed in another room will be explained. FIG. 10 is a sectional view showing a corner part of the room;
27. 27 is a wall surface. 28.28 is a synthetic resin wire gutter. This synthetic resin line gutter 28, 28 is provided with a round hole 29 or an electrical connector 30 such as an outlet. An automatic power supply circuit breaker 31 may also be provided if necessary. The buried electric wire 6 of the carpeller) 1 is connected to an outlet provided in the synthetic resin wire gutter with a plug as shown in Fig. 1 or a connector 8'' as shown in Figs. 8 and 9, and It can be connected to a commercial power source through an automatic circuit breaker 31 or to electrical equipment in another room through a connector 32.

As described above, according to the present invention, an electrically insulating material layer 3 having elasticity is provided below the fiber layer 2, and a thin electrical conductor 4.4 is covered with a rubber 5 (7) on this electrically insulating material layer 3. Since the carpet 1 has a structure in which N2 is buried, there is no need to remove the carpet and install electrical wiring every time the arrangement of multiple desks is changed in an office. Since the elastic insulating material layer 3 below the fiber N2 can be exposed and wiring can be carried out by cutting it open, the wiring work is extremely efficient, and after removing the connector 9, the fiber If layer 1 is returned to its original state, it can be used as before.
