Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a wire tensioning device for stretching a pair of parallel electric wires for connecting lighting equipment.

[Conventional technology]

Conventionally, as shown in FIG.
There is a lighting device in which a lighting device 54 is connected to the device. The parallel electric wires 52 and 53 are stretched by attaching the mounting devices 50 and 51 to a wall or the like.

[The problem that the idea attempts to solve]

However, as shown in FIG.
When the walls 55 and 56 to which the 0 and 51 are attached are perpendicular to each other, the distance between the parallel electric wires 52 and 53 becomes narrow, causing the problem that the lamp 54 cannot be attached.

Therefore, the purpose of this invention is to provide a wire tensioning device that can match the distance between the parallel wires to the size of the lighting fixture to which they are connected, regardless of the angle formed by the mounting surfaces on which both ends of the parallel wires are attached. The goal is to provide the following.

[Means to solve the problem]

The wire tensioning device of this invention houses a wire winder with a rotation stop mechanism in a case, and the case is provided with a slit for drawing out the wire extending in a direction perpendicular to the rotation axis of the wire winder. It is.

Further, a scale may be provided along the slit of the case to indicate the direction in which the wire is drawn out.

[Effect]

When the wire tensioning device of this invention is attached to the end of the wire and fixed to a wall etc., the length of the wire is adjusted by winding the wire into a wire winder, and the wire is stretched along the slit of the case. By changing the drawing direction, the distance between the parallel electric wires can be adjusted to the size of the lighting equipment, regardless of the angle formed by the mounting surfaces to which both ends of the parallel electric wires are attached.

Furthermore, by providing a scale along the slit of the case, only one side of the parallel electric wire can be attached, and the other can be attached in accordance with the scale of the wire tensioning device in the attached state, improving workability.

〔Example〕

An embodiment of this invention will be described based on FIGS. 1 and 7.

FIG. 1 shows an enlarged view of the wire tensioning device A, in which 10 is a wire winder and 11 is a case. The wire winder 10 has a U-shaped base portion 12.
A rotary shaft 13 rotatably spanned between the upper and lower halves of the pedestal 12, a ratchet 14 fixed to the rotary shaft 13 on the upper surface of the pedestal 12, a knob 15 provided on the ratchet 14, and a rotary shaft 13 attached to the ratchet 14. Rotation stop mechanism 1 consisting of interlocking leaf springs
It consists of 6. In addition, case 11 is
The back side is an opening 17, which is formed in a size that can accommodate the wire winder 10, and the front side has a rotating shaft 1.
It has a slit 18 for drawing out electric wires extending in a direction perpendicular to the wire. The electric wire 19 connects to the rotating shaft 1
3 and passed through the slit 18. FIG. 2 shows an external view of the wire tensioning device A.

Figure 3 shows the wire tensioning device A used for parallel wires 20, 2.
The state shown is that they are attached to both ends of 1.
22 is a lighting fixture connected to parallel electric wires 20 and 21.

4 and 5 show wire tensioning devices A at both ends of parallel wires 20 and 21 being connected to walls 2 orthogonal to each other.
3 and 24 are shown. Turn the knob 15 of each wire tensioning device A to adjust the length of the wires 20, 21 to match the spacing between the two parallel wires 20, 21 to the size of the lighting fixture 22, cover the case 11, and set the wall 23, Fixed at 24.

In addition, FIGS. 6 and 7 show the wall 25 and the ceiling 2.
6 is shown.

According to the wire tensioning device configured in this way,
By adjusting the length of the electric wires 20, 21 using the electric wire winder 10 and changing the drawing direction along the slit 18, regardless of the angle formed by the wall or ceiling to which the parallel electric wires 20, 21 are attached, Both wires 2
The spacing between 0 and 21 can be adapted to the size of the luminaire.

Other embodiments of this invention are shown in Figures 8 to 10.
As shown in the figure. The wire tensioning device B of this example is the eighth
As shown in the figure, a scale is provided along the slit 18 of the case 11 to indicate the direction in which the wire is drawn out. If a scale is provided in this way, the 9th
As shown in the figure, one parallel electric wire 20 is connected to a wall 23,
24, and match the scale of the wire tensioning device B to the other parallel wire 21 as shown in FIG.
can be installed, improving workability. Note that numbers may also be provided on the scale.

[Effect of idea]

When the electric wire tensioning device of this invention is attached to the end of the electric wire and fixed to a wall etc., the electric wire is wound on a wire winder to adjust the length of the electric wire, and the electric wire is stretched along the slit of the case. By changing the drawing direction of the parallel electric wires, the distance between the two electric wires can be adjusted to the size of the lighting equipment, regardless of the angle formed by the mounting surfaces to which both ends of the parallel electric wires are attached.

In addition, by providing a scale along the slit of the case, it is possible to install only one side of the parallel wire and the other to match the scale of the wire tensioning device that is being installed, improving workability. Effects can be obtained.
