Description

[Detailed Description of the Invention] This invention relates to a cable raising device used for floor cable wiring.

BACKGROUND ART Conventionally, the following two methods have been mainly used for wiring telephones, electronic devices, etc. on the floor of a room. The first method is to run the cable through a conduit pipe that has been pre-buried in the floor, and the second method is to route the cable on the floor and then cover it with a wire protector.

However, the former method has the advantage of being able to route cables without protruding from the floor;
The construction cost of installing conduit pipes is high;
Another problem is that it lacks flexibility when changing wiring. Further, although the latter method has the advantage of being easy to construct and having low construction cost, it also has the disadvantage that the wire protector protrudes from the floor surface and obstructs pedestrian passage and transportation of goods.

In consideration of these circumstances, the applicant
-142814, Utility Application No. 142815, etc. proposed the ``floor cable''. These floor cables are made by arranging a large number of core wires in a horizontal row at intervals, mutually shielding each pair, and then applying insulation coating to these core wires to form a tape-like structure as a whole. Because it is thin, it can be placed under a carpet or the like for wiring without protruding from the floor, and it has good crosstalk characteristics, making it suitable for telephone wiring.

In order to raise these floor cables and protect the raised parts, the applicant filed a patent application filed in 1983.
-68256, Utility Application No. 57-50208, etc., proposed a ``floor cable raising device.'' These lifting tools are provided with a support that is approximately parallel to the floor surface and around which the floor cable is wound and raised up, inside a hollow cap, and furthermore, a support body is provided at the top of the cap for pulling out the floor cable. It has an insertion hole and is excellent in protecting the rising part of the floor cable.

However, when starting up the floor cable, it is necessary to wind the floor cable around the support, so there is room for improvement in terms of workability. Furthermore, when installing the floor cable, it is necessary to cut out a hole in the carpet into which the cap fits, which poses a problem in terms of appearance.

This idea was proposed in consideration of the above-mentioned circumstances, and it has good workability and makes it possible to use the notch formed in the carpet when standing up floor cables that are routed under the carpet. The purpose of this invention is to provide a floor cable raising tool that can be used to raise floor cables.

EMBODIMENT OF THE INVENTION Hereinafter, the cable raising tool based on this invention is demonstrated based on the Example shown in drawing.

FIGS. 1 to 5 show examples of floor cable wiring using cable raising tools.

The floor cable 1 used for this wiring is, for example, a cable in which a large number of core wires are arranged horizontally in a row and are integrally coated with insulation. This floor cable 1 is connected to a terminal box 2, and
As shown in FIG. 1, the required number of core wires (for example, four in the case of a push-button telephone) are sequentially torn and branched from both sides.

In addition, as shown in Fig. 2, the branched floor cable 1 is routed with a carpet 3 laid underneath, and a cut 4 is made in the carpet 3 to connect the cable to the floor 5. The telephone 8 is raised by a fixture 6 and connected via a rosette 9 to a telephone 8 placed on a desk 7.

This cable raising tool 6 will be explained below.

This cable erecting tool 6 is, for example, integrally molded from a material having more rigidity than the floor cable 1, such as rubber, metal, or engineering plastic, and includes a mounting plate 10 for mounting on the floor 5 as described later. The vertical member 11 stands up from this mounting plate 10. The mounting plate 10 is formed in the shape of a bent thin plate, and has a groove 12 formed in its lower surface for passing the floor cable 1 through, and both sides of the groove 5 are flat plate parts. The vertical member 11 is attached to the mounting plate 1
An insertion hole 13 is integrally provided so as to protrude in a direction perpendicular to the upper surface of the floor cable 1, and an insertion hole 13 through which the floor cable 1 is inserted in the vertical direction is formed. Also,
This insertion hole 13 is parallel to the groove 12 in the width direction,
and are connected at the bottom. A corner 14 formed at a bending point between the insertion hole 13 and the groove 12 is formed to have a larger curvature than the minimum curvature that allows the floor cable 1 to bend. Further, it is advantageous to make the wall thickness around the insertion hole 13 of the vertical member 11 thin enough to support the elastic reaction force of the bent portion of the floor cable 1.

As shown in FIG. 3, the total height from the bottom of the flat plate part of the mounting plate 10 to the top end of the vertical member 11 is approximately equal to the thickness of the carpet 3 to which this raising tool 6 is applied. It is set.

In addition, in order to reinforce the floor cable 1 near the upper end of the vertical member 11, a protective tube 15 made of rubber or the like is used as necessary.

Hereinafter, a specific usage example of this cable raising tool 6 will be explained.

To raise the floor cable 1 using the cable raising tool 6, for example, the floor cable 1 is bent and passed through the groove 12 and the insertion hole 13, and then the mounting plate 10 is attached to the floor with adhesive or the like. , form a notch 4 in the carpet 3,
This is done by inserting the vertical member 11 of the cable raising device 6 together with the floor cable 1 into this cut 4 . In addition, in the case where the jacket is made by joining pieces of triangle, square, hexagonal, etc., the joints can also be used as the cuts 4. As an example, FIG. 5 shows an example in which a square carpet is used.

Furthermore, by appropriately changing the dimensions and shapes of the groove 12 and the insertion hole 13, this cable raising tool 6 can be applied to cable raising tools of other shapes such as round cables.

As is clear from the above explanation, this invention provides the following effects.

(b) By fixing the floor cable to the floor while passing it through the groove and insertion hole, it can be installed not only in the insertion hole of the vertical member but also in the mounting plate.
Movement in the left and right direction is restrained by the flat plate portions on both sides of the groove, and the right-angled bent shape is supported in this restrained state, thereby increasing stability. Also,
Without complicated bending of floor cables,
Pass the floor cable through the insertion hole of the vertical member,
Just by placing it on the floor along the groove of the mounting plate, it can be held in an upright position, making it easy to work.
Furthermore, since the bent shape is at a right angle, sharp bends in the floor cable are prevented, and wiring can be performed without impairing reliability.

(b) Since the overall height is set almost equal to the thickness of the carpet, it can be installed without protruding from the surface of the carpet.
By making the wall thickness of the vertical member thinner, it does not stand out from the surface of the carpet and does not spoil the aesthetics of the room.

(c) Furthermore, when the vertical member is removed from the notch in the carpet, the notch is closed due to the elasticity of the carpet, making it less noticeable and causing fewer defects in appearance.
