Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a messenger wire fixture for fixing equipment, such as electronic equipment, to a stretched messenger wire.

[Conventional technology]

An example of this type of fixture is explained in Fig. 3.
Messenger wire fixing device is TV signal amplifier 5
It consists of a mounting bracket 52 fixed to the upper part of the mounting bracket 1 and a presser metal fitting 54 inserted through a bolt 53 attached to the mounting bracket 52, and a nut 58 screwed onto the bolt 53 is loosened to open the space between the mounting bracket 52 and the presser metal fitting 54. Metal fittings 5
The television signal amplifier 51 was attached to the messenger wire 57 by fitting the messenger wire 57 into the wire guide grooves 55 and 56 of No. 2 and 54 and tightening the nut 58.

[Problem that the invention attempts to solve]

However, in such a messenger wire fixing device, the wire guide grooves 55, 5 of the metal fittings 52, 54
6, while supporting the weight of the television signal amplifier 51 with one hand,
The wire guide grooves 55 and 56 must be kept open with the other hand. Furthermore, when tightening the nut 58, if the TV signal amplifier 51 is not supported, there is a risk that the presser metal fitting 54 will come off from the messenger wire 57, and a bending moment will act on the bolt 53 due to the weight of the TV signal amplifier 51. This becomes a cumbersome task of supporting the television signal amplifier 51 with one hand while tightening the nut 58 with the other hand. Moreover, this work is difficult because it involves work at high places with unstable footing.
There are drawbacks that can be dangerous.

The present invention has been made in view of the above-mentioned points, and an object of the present invention is to provide a messenger wire fixture that can be easily fitted into and fixed to the messenger wire.

[Means for solving problems]

The first configuration of the present invention to achieve this purpose is
This will be explained using FIG.

A wire support part 6 is erected on the mounting seat 5 on which the device 2 is mounted on the lower surface, and a recess 9 is provided in the lower half of the front surface of the wire support part 6, and a guide groove 11 is provided at the top of the recess 9 for guiding the upper part of the messenger wire 10. This guide groove 1
A mounting bracket 3 is provided with a mounting part 8 for rotatably attaching a presser bracket 4, which will be described later, at the front above the mounting bracket 1.
A mounting part 16 is provided in the middle of the bent piece 12 to be rotatably attached to the mounting part 8, and a bolt 14 which is brought into contact with the upper front surface of the wire support part 6 is screwed into the upper part of the bent piece 12. A receiving portion 18 that comes into contact with the lower part of the messenger gear 10 that comes into contact with the guide groove 11
The presser metal fitting 4 formed with the above-mentioned shape constitutes a messenger wire fixing device.

[Effect]

Messenger wire 1 with the proposed fixing device stretched
Since the bolt 14 is loosened before insertion into the recess 9, the presser metal fitting 4 can be rotated in the vertical direction within the recess 9. Now, attach the proposed fixing device to the mounting wire 1 between the mounting seat 5 of the mounting bracket 3 and the holding bracket 4.
0, and when the messenger wire 10 reaches the lower part of the recess 9, if there is a receiving part 18 of the presser metal fitting 4 above it, rotate the receiving part 18 downward, and then guide the mounting metal fitting 3. Fit the groove 11 into the messenger wire 10. As a result, the device 2 to be attached to the main fixture and the mounting bracket 3 is connected to the messenger wire 1.
It is stably supported at 0. Here, the receiving part 18 is brought into contact with the lower part of the messenger wire 10, and the bolt 1
4 is brought into contact with the mounting bracket 3 and tightened, the presser metal fitting 4 rotates clockwise around the mounting part 8, and the mounting bracket 3 and the presser metal fitting 4 release the messenger wire 10.
Since the wires are firmly clamped, the attachment of the device 2 to the messenger wire 10 is completed. The bolt operation required for installing this device does not require supporting the weight of the device 2, so it can be easily carried out.

To remove the proposed fixing device 1 from the messenger wire 10, loosen the bolt 14 to enable the presser metal fitting 4 to rotate up and down, and then lift the proposed fixing device 1 a little and place the messenger wire 10 in contact with the mounting seat 5. On the other hand, a wire passage space is secured between the mounting seat 5 and the presser metal fitting 4, and the proposed fixture 1 is moved back and removed from the messenger wire 10 using the wire passage space.

〔Example〕

Embodiments of the present invention will be described based on the drawings. 1st
In the figures and FIG. 2, a messenger wire fixture (hereinafter simply referred to as a fixture) 1 is composed of a mounting bracket 3 that is attached to the top surface of a device 2, and a presser bracket 4 that is rotatably attached to the mounting bracket 3.

The mounting bracket 3 has a wire support part 6 erected integrally with the mounting seat 5 along the rear edge of the mounting seat 5, and a recess 9 in the lower front half of the wire support part 6 and a recess 9 in the recess 9. A guide groove 11 for guiding the upper part of the messenger wire 10 is provided horizontally at the top, and a pair of arms 7, 7 are provided along the front part of the guide groove 11 to protrude parallel to the mounting seat 5. A support shaft 8 is attached to the part. The height of the recess 9 is set to twice the diameter of the messenger wire 10 plus the thickness of the lower piece 17 of the presser metal fitting 4.

The presser metal fitting 4 has a bolt 14 attached to a screw hole 15 formed at the upper end of the upper piece 13 of the bent piece 12.
A J-shaped bearing 16 that is rotatably hooked onto the support shaft 8 of the mounting bracket 3 is protruded in the middle, and the lower piece 17 of the bent piece 12 has a Messenger wire 10 fitted in the guide groove 11 at the tip. Receiving part 18 for abutting the lower part
is formed. This receiving portion 18 is connected to the guide groove 11
When the bolt 14 that is in contact with the lower part of the messenger wire 10 fitted in the
Loosen to release the pinch.

Note that the shapes of the mounting bracket 3 and the holding bracket 4 are not restricted to the embodiments illustrated, and can be modified in various ways within the scope of the gist of the present invention. For example, the pair of arms 7 and the support shaft 8 may be provided on the upper piece 13 of the presser metal fitting 4, and the bearing 16 may be provided protruding from the wire support portion 6. In this case, if the pair of arms 7, 7 and the support shaft 8 are provided protruding from the outer surface of the upper piece 13 (the side with the bolt head), the bearing 16 provided on the wire support part 6 will not penetrate through the upper piece 13. Support shaft 8
will support. Further, a cylindrical bearing may be used instead of the J-shaped bearing 16.

[Effect of idea]

As is clear from the above explanation, according to the present invention, the fixing device is inserted into the messenger wire from between the mounting seat of the mounting bracket, which is always open, and the holding bracket. Since the guide groove of the mounting bracket is suspended from the messenger wire,
The fixing device can be easily inserted into and suspended from the messenger wire. Further, the bolt operation for fixing the fixing device to the messenger wire does not require supporting the weight of the device, so it can be easily carried out. Therefore, this type of installation work, which involves work at high places, can be carried out safely and easily.
