Description

[Detailed Description of the Invention] This invention relates to a floor cable raising tool 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 is 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 has the problem that the wire protector protrudes from the floor surface and obstructs the passage of pedestrians and the 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 row horizontally 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 laid under carpets and wired without protruding from the floor, and it has good crosstalk characteristics, making it suitable for telephone wiring. There remains the problem of how to make the stand-up part stand up, or how to protect the stand-up part.

This idea was proposed in consideration of the above-mentioned circumstances, and involves pulling out the floor cables laid under the modular carpets, which are spread in large numbers on the floor, from the joints of the modular carpets. The purpose of this invention is to facilitate the construction of the standing part of the floor cable by pinching and bending the floor cable and modular carpet by the top plate and bottom plate that are connected together. It is something.

This invention will be explained below based on embodiments shown in the drawings.

1 to 4 show a wiring row of floor cables using a cable raising device according to a first embodiment of this invention.

That is, the floor cable 1 is connected to an outlet box 2 as shown in FIG.
At the same time, the required number of core wires (for example, four in the case of a push-button telephone) are torn from the sides and branched out, and as shown in Figure 2, a module car is formed. It is raised from the seam of the pet 3 and connected to a telephone 5 placed on a desk 4 via a rosette 6. A cable erecting tool (hereinafter abbreviated as erecting tool) 7 according to this invention is used in a portion indicated by a chain line A in FIG. 2.

As shown in FIGS. 3 and 4, this lifting tool 7 is formed by bending a highly elastic plate material such as spring steel into a U-shape (or U-shape), and is used to lift the module carpet 3. A floor cable 1 whose ends are held together and folded back approximately 180 degrees in a U-shape (or U-shape) is held together with a modular carpet 3 from both sides.

Then, the top plate 8 and bottom plate 9 of this rising tool 7
are opposed to each other with an interval S, and
They are integrally connected via the side plates 10 so as to be elastically deformable in the direction of mutual separation, and the distance S is the thickness of the modular carpet 3 t ₁ , and the floor cable 1
The thickness is set to be t ₂ , and the relationship is S<t ₁ +2t ₂ . Further, the upper plate 8 is formed with a notch 8a for pulling out the floor cable 1 almost vertically upward.

When lifting up the floor cable 1 using the lifting tool 7 configured as described above, first pull out the floor cable 1 from the seam of the module carpet 3, and then pull out the floor cable 1 from the module carpet. The ends of the carpet 3 may be pinched and folded back, and the folded portion may be held together with the modular carpet 3 by the raising tool 7, and then pulled out from the notch 8a and raised. As shown in FIG. 3, the raising tool 7 holds the modular carpet 3 and the floor cable 1 in a state where the bristles 3a of the modular carpet 3 are bent.

Further, FIGS. 5 and 6 show a second embodiment of this invention, in which a recess 11 for fitting the floor cable 1 into the inner surface of the raising tool 7 is formed, and the upper surface of the bottom plate 9 That is, the recessed portion 1 of the surface of the modular carpet 3 facing the core material 3b
Core material 3b of modular carpet 3 on both sides of 1
A plurality of protrusions 12 are provided to prevent the lifting tool 7 from falling off (movement to the right in FIG. 5). In addition, the distance S' between the top plate 8 and the bottom plate 9 of the rising tool 7 is set so that S'<t ₁ approximately takes into account the fact that the floor cable 1 is fitted into the recess 11. There is.

The raising tool 7 of the second embodiment can prevent the floor cable 1 from shifting in the width direction by holding the floor cable 1 in a state where it is fitted into the groove 11, and can also prevent the floor cable 1 from shifting in the width direction. By biting into the core material 3b of the modular carpet 3, the lifting tool 7 can be prevented from falling off.

In the first and second embodiments, the upright tool 7 is formed by bending a plate material such as spring steel. Other possible materials may also be used, such as plastic.

In addition, the floor cable 1 is connected to the notch 8a of the upper plate 8.
In order to prevent wear due to contact with the floor cable 1, the floor cable 1 may be covered with a protective tube made of rubber, plastic, etc.

As is clear from the above explanation, this invention involves folding the floor cable pulled out from the seam of adjacent modular carpets by sandwiching the end of one of the modular carpets, and also connecting the floor cables to each other. It is characterized in that it is integrally held with the modular carpet by a stand-up tool having a top plate and a bottom plate with a space between them,
It has the following actions and effects.

(a) Since the floor cable can be pulled out and raised from the joint of the modular carpet, there is no need to cut the modular carpet.

(b) The raising tool can be easily fixed by holding the floor cable and the modular carpet.

(c) The rising part of the floor cable is protected by the rising tool.
