Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention mainly relates to an undercarpet cable support structure suitable for wiring undercarpet cables for power use.

"Conventional technology" In recent years, microcomputers and OA equipment used indoors in offices, laboratories, factories, etc. are connected to each other or to a common data bank, and the data held by each equipment is transferred. So-called local network systems for mutually effective use are being planned and put into practical use in various places.

As communication cables used for such purposes, for example, the "undercarpet cable" proposed by the applicant in U.S. Patent Application No. 58-123468, U.S. Pat. No. 58-123469, U.S. Pat. By laying this under-carpet cable under the carpet etc. and wiring between each of the above-mentioned devices, each of the above-mentioned devices can be connected without spoiling the aesthetics of the room.
It has become possible to interconnect OA equipment.

In addition to the above-mentioned communication cables, each of the above-mentioned office automation equipment requires a power cable, and in order to further enhance the aesthetics of the room, a belt-shaped power cable is used as the power cable, and it is placed under the carpet. It is planned to enable the wiring of

``Problems to be solved by the invention'' By the way, the power cable mentioned above requires a larger current capacity than a communication cable, so it requires a conductor with a larger cross-sectional area.
As the cross-sectional area of a conductor increases, its rigidity tends to increase.

As mentioned above, if the rigidity of the cable increases, the bent cable will have a large elastic force, and for example, a large force may be required to fix the cable, or the elastic force may cause the carpet to close near the bend. There are problems such as being lifted up.

The present invention was proposed in view of the above-mentioned circumstances, and its main purpose is to provide a wiring structure that can securely fix a highly rigid power undercarpet cable.

"Means for Solving the Problem" In order to achieve the above object, the present invention provides a pair of mounting members that are fixed to a wall surface near the floor at two points spaced apart from each other in the horizontal direction, which are spaced apart from the wall surface. A plurality of clamping parts are connected to each other by a pressing member at a position, and a space is provided between the pressing member and the wall surface, and the plurality of clamping parts are set in a predetermined positional relationship with respect to the pressing member. By arranging the undercarpet cable, the undercarpet cable is fixed to the wall at a plurality of locations including the wall surface and the protruding portions from the wall surface.

"Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, referring to FIG. 1, the structure of a power undercarpet cable 1 that is wired using the structure according to the present invention will be explained. As shown in FIG. A plurality of (three in the illustrated example) conductors 2 formed in a plate shape
are lined up in the same plane and are integrally covered with an insulating material 3 made of polyvinyl chloride or the like, which is laid with a bottom shield 5 interposed between it and the floor 4, and is further fixed to the floor 4. It is attached to the floor 4 while being covered by a top shield 6.

The bottom shield 5 is made of, for example, plastic such as polyvinyl chloride, that is, a material that has a buffering effect due to elastic deformation and has excellent electrical insulation properties. Further, the top shield 6 is constructed such that a fixing means 6a such as a double-sided adhesive tape is provided at the widthwise end of a thin plate made of steel or the like having high mechanical strength.

Next, one embodiment of the support structure for the undercarpet cable 1 will be described with reference to FIGS. 2 and 3.

That is, to explain the structure of the protective plate 7 that constitutes this support structure, this protective plate 7
is formed by punching and bending a steel plate, and includes a first holding part 11 fixed to a baseboard 10 that frames a wall surface 9 near the floor 4 on which the carpet 8 is laid, and It has a structure in which a second clamping part 12 fixed to the upper wall surface 9 is integrally connected.

The first and second holding parts 11 and 12 each include an attachment member 13 attached to the wall surface 9 (or the side surface of the baseboard 10) and the attachment member 1.
3 and a holding member 14 that connects the baseboards 10 and 3 to each other, and are set in a positional relationship parallel to each other and offset from each other in the thickness direction over a dimension corresponding to the thickness dimension of the baseboard 10. In this state, they are connected to each other via the connecting member 15. The connecting member 15 is connected to both the clamping parts 11 and 1.
2 are connected to each other, and the undercarpet cable 1 is sandwiched between the baseboard 10 and the upper surface of the baseboard 10.

Further, the mounting member 13 is attached to the wall surface 9 (or baseboard 10) by means of fixing means 16 such as wood screws.
On the other hand, the holding member 14 is provided at a position spaced apart from the mounting member 13 in the thickness direction, and is attached between the wall surface 9 (or baseboard 10) and the underside. A space 17 is formed through which the carpet cable 1 is inserted.

Note that the reference numeral 18 in the figure is a terminal box,
One end of the undercarpet cable 1 is connected to the terminal box 18.

In each of the above embodiments, a gap is provided between the protective plate and the undercarpet cable, but the undercarpet may also be sandwiched between the protective plate and the wall while being in close contact with them. good. Further, the specific shape of the protective plate applied to the wiring structure of the present invention is not limited to those of the above-mentioned embodiments, but may include a mounting member attached to a wall near the floor and integrally formed with the mounting member. It goes without saying that other shapes may be employed, including a clamping portion that forms a space for the undercarpet cable to be inserted between it and the wall surface.

"Effects of the Invention" As is clear from the above explanation, the present invention fixes the mounting members at two points spaced apart from each other in the surface direction of the wall near the floor, and also inserts the undercarpet cable between the wall and the wall. Since the mounting members are connected to each other by the clamping members that form a common space, a power undercarpet cable with a large cross-sectional area is inserted into the space between the wall surface and the clamping member, and the It can be held securely against rigidity, so it can be used not only for communication cables that connect OA equipment, etc., but also for power cables that connect these equipment and power sources under the carpet. This has the effect of making wiring possible and further enhancing the aesthetics of rooms such as offices. In addition, since the undercarpet cable is fixed to the wall surface and the part of the skirting board that protrudes from the wall using multiple holding parts, the undercarpet cable cannot be attached to the wall surface even though there are protruding parts on the wall surface. Can be placed along. In addition, the baseboard is stronger than the materials that make up the wall, such as plasterboard or plasterboard, so it has a greater holding power for wood screws, etc.
This has the effect that the undercarpet cable can be securely fixed.
