Referring to FIG. 1, the leg portion 20 includes a base portion 21 formed in a substantially rectangular shape in a plan view, an upright portion 22 that is bent at a right angle from one end of the base portion 21, and rises up, and an upright portion 2 is formed.
2 is a sheet metal member integrally provided with a fixed attachment portion 23 extending from the upper end portion of the base portion 2 and extending obliquely in a direction away from the other end of the base portion 21.

The base portion 21 is fixed to the floor surface by fixing means such as concrete bolts or tape (not shown), and when used, the mat 5 with artificial turf (FIG. 1).
(See)). The upright portion 22 serves to float the electric wire receiver 30 from the floor surface. Standing part 2
A hinge 24 having an axis parallel to the longitudinal direction of the wiring plate 2 in the wiring stations S1 and S2 is attached to the upper end portion of the front surface (the surface facing the other end side of the base portion 21) of 2. The movable mounting portion 25 is rotatably supported via the hinge 24. The movable mounting portion 25 is shown in FIG.
In order to maintain the posture shown by the solid line, a pair of stopper members (maintaining means) 26 arranged on both sides of the hinge 24 are fixed to the upper end of the front surface of the standing portion 22.

Both the fixed mounting portion 23 and the movable mounting portion 25 are for mounting the electric wire receiver 30 while supporting it in a gutter shape.
It is open like a letter. The fixed mounting portion 23 is the base portion 21.
On the other hand, the movable attachment portion 25 has a plate piece 25A connected by the hinge 24 and a base end portion fixed to both side portions of the plate piece 25A.
The plate structure has a frame structure integrally including a pair of side pipes 25B whose tip ends extend along the longitudinal direction of the plate piece 25A and an end pipe 25C fixed to the tip end between the side pipes 25B and 25B.

FIG. 4 is an enlarged schematic view showing an enlarged main part of the electric wire protection device of FIG. With reference to the figure, as described above, the movable mounting portion 25 is rotatably provided via the hinge 24, and the direction A1 away from the fixed mounting portion 23 around the axis 24A of the hinge 24. Is configured to be rotatable in a direction A2 which is close to Then, with respect to the separating direction A1, the rotation amount is restricted by the stopper member 26, so that the posture shown by the solid line in FIG. 3A is maintained, and the rotating amount in the approaching direction A2 is As shown in FIG. 4, the movable mounting portion 25
It is regulated by the regulation projections 27 attached to both end portions in the width direction of the surface facing the fixed attachment portion 23, so that no pinching occurs between the both attachment portions 23 and 25.

With reference to FIGS. 1 and 3, the electric wire receiver 30
Is obtained by hanging a vinyl sheet material into a substantially U-shaped open shape and attaching the vinyl sheet material to the attachment portions 23 and 25, thereby forming a generally gutter-shaped shape. In order to maintain the electric wire receiver 30 made of a vinyl sheet material in a gutter shape along the longitudinal direction, as shown in FIG.
Wires 31 on the fixed side are stretched between 3, 23, ..., Wires 32 on the fixed side are stretched between the movable mounting portions 25, 25 ,.
In the state in which 3 is slackened in a U shape, both widthwise end portions 34 and 35 are folded back to the outer circumferences of the corresponding wires 31 and 32 and taped.

Further, in order to prevent the terminal fitting 7 attached to the end portion of the length-adjusted electric wire 6 from being caught, both end portions in the longitudinal direction of the electric wire receiver 30 are also attached to the corresponding mounting portions 2.
Taped to the edges of 3, 25. As a result, the vinyl sheet material attached to the fixed attachment portion 23 side has its upper end side facing the lower portion of the wiring board 2 and its lower end side approaches the operators of the wiring stations S1 and S2 as specific stations. Thus, the movable side receiving surface 30A is defined as a pair, and the portion attached to the movable mounting portion 25 is arranged on the operator side facing the fixed side receiving surface 30A to form a pair with the movable side receiving surface. The surface 30B is formed continuously.

Then, the movable side receiving surface 30B is attached to the movable attaching portion 25, so that the hinge 24 is moved.
By rotating around the axis 24A of the wiring board 2, the upper end side (the portion that covers the wire 32) of the movable side receiving surface is the wiring board 2.
Is maintained in a receiving posture capable of receiving the scaled electric wire 6 which is hung away from the wiring board 2 in a state in which it is allowed to approach the wiring board 2.

With the above construction, the wiring station S1,
When the scaled electric wire 6 is laid in S2, the scaled electric wire 6 can be received by the electric wire receiver 30 by carrying out the wiring work while the scaled electric wire 6 is hung on the electric wire receiver 30. Therefore, it is possible to protect the terminal fitting 7 and the like fixed to the end portion of the scaled electric wire 6 during the wiring work. Further, since the adjusted electric wire 6 having the electric wire receiver 30 hanging down is levitated from the floor surface, an operator does not accidentally step on the adjusted electric wire 6.

As described above, according to the above-described embodiment, when laying the scaled electric wire 6 at the wiring stations S1 and S2, the operator can attach the end portion of the scaled electric wire 6 hung from the wiring board 2 to the operator. Does not accidentally step on the end of the scaled electric wire 6 or get caught in the floor surface, so that the scaled electric wire 6 can be reliably protected, and it is provided in the wiring stations S1 and S2. Since the scaled electric wire 6 is protected by the equipment described above, one equipment can be shared by a plurality of wiring boards, and as a result, the cost of the equipment can be significantly reduced. Further, the stations after the wiring stations S1 and S2 do not hinder the work. Therefore,
According to the above-mentioned embodiment, there is a remarkable effect that the workability is good and the adjusted electric wire 6 to be laid can be protected with an inexpensive structure.

Moreover, since the electric wire receiver 30 is made of a material having a high flexibility and a low friction coefficient, such as a vinyl sheet material, the parts attached to the hanging scale electric wire 6 are caught. It will disappear and will not get scratched easily.
5 and 6 show a wire protection device 1 during wiring work.
6 is a schematic side view showing the action of 0.

As shown in FIG. 5, the worker P stands in front of the electric wire receiver 30 and performs the wiring work in front of the wiring plate 2. At this time, the worker P approaches the wiring board 2, and the foot is inside the component of the receiving surface 30B on the movable side (the movable mounting portion 25 or the wire 32 stretched on the movable mounting portion 25). Then, the movable mounting portion 25 integrally rotates in the counterclockwise direction in the figure and is displaced to the close attitude as shown in FIG. As a result, the electric wire receiver 30 allows the worker P to approach the wiring board 2 as much as possible, so that the electric wire receiver 30 does not obstruct the work area of the worker P. There is an advantage that workability is improved even during wiring work.

In addition, since the electric wire receiver 30 is formed of a vinyl sheet material in which slack is formed, even if the electric wire receiver 30 is closed in the close position, it is accommodated inside the slack formed at the bottom thereof. The end of the measuring wire 6 is the receiving surface 30.
Since it is not sandwiched between A and 30B, the electric wire can be protected more reliably. The above-described embodiment is merely an example of a preferred specific example of the present invention,
The present invention is not limited to the above embodiment.

For example, as the material of the electric wire receiver 30 described above, the vinyl sheet material as described above is suitable,
The present invention is not limited to the above-described embodiment, and for example, a highly flexible plastic plate material (trade name “Dampler”) may be adopted. It is preferable that the plastic plate member has a groove extending along the longitudinal direction (horizontal direction) of the wiring plate 2 so that friction is unlikely to occur between the hanging end and the end of the scaled electric wire. . Even in that case, as described above, the movable mounting portions connected by the hinge may be adopted to open and close, and both the receiving surfaces 30A and 30B are fixed in a V-shape. May be adopted.

Needless to say, various design changes can be made within the scope of the claims of the present invention.

[0029]

As described above, according to the present invention,
At stations such as wire laying stations where the wires are hung down, it is possible to perform the work while the sized wires are hung on the wire receivers. It will not step on the part or get caught on the floor,
In addition to being able to reliably protect the scaled wire, the equipment installed at the above-mentioned specific station protects the scaled wire, so one equipment can be shared by multiple wiring boards. The equipment cost can be reduced significantly. In addition, there is no hindrance to the work at the station where the wires are not hung. Therefore, according to the present invention, there is a remarkable effect that the workability is good, and the wire to be laid can be protected with an inexpensive structure.

In particular, when an electric wire receiver having a rotating side receiving surface is employed, the movable side receiving surface allows the operator to approach the wiring board as much as possible. There is an advantage that the electric wire receiver does not hinder the work area of a person and workability is improved even in the wiring work from this point. Further, when the receiving surface on the fixed side and the receiving surface on the movable side are continuous through the slack portion, the receiving surface on the movable side approaches the receiving surface on the fixed side and the electric wire receiver closes. Even if it reaches, there is no possibility that the end portion of the scaled electric wire will be caught between both receiving surfaces, and the electric wire can be protected more reliably.
