Description

[Detailed description of the invention] [Industrial application field] The invention relates to a wiring ring used for erection of a wiring such as a drop wire on a rectangular hardware such as a protruding hardware.

[Related Art] Negotiation of a communication line from a terminal pole to each house is performed as follows.

First, connect one end of the wiring for the house to the terminal pole suspended on the tip side of the protruding hardware of the communication column, protrude the communication line on the lower surface of the hardware, protrude the wiring of the crawled part, and protrude the spacing between the hardware Then, tie (fasten) with a tying cord, etc., further project the wiring on the communication pole side, hold it to the communication pillar higher than the hardware position with the fastening bracket, etc., and wire the wiring on the other end side from the stopped part to the house I was going to build it.

[Problem to be solved by the present invention] However, the work of performing a plurality of shackles with a tying string or a binding wire in a high place where the scaffold is unstable such as on a pillar is extremely troublesome and requires a lot of work time. Since it was a work, improvement was required.

An object of the present invention is to provide a wiring ring that can be easily attached to a metal piece having a rectangular cross section such as a protruding metal piece and can easily perform wiring such as a drop wire.

[Means for Solving the Problems] In this invention, a steel wire of a predetermined length is bent in a loop shape in the opposite direction in the middle of the longitudinal direction to form a hanging portion of the wiring, and the hanging portion is protruded to form a metal part or the like. In order to suspend the steel wire on the rectangular hardware, the steel wires at both ends from the hanging portion are bent at right angles in opposite directions at predetermined intervals, respectively, to form a U-shaped band portion, and the tip of the steel wire on which the band portion is formed is further squared. To form a locking portion, and form a guide portion by bending the distal end portion of the locking portion at an obtuse angle outwardly of the rectangle formed by the U-shaped band portion to form a guide portion in the leg opening direction and the torsion direction. A shape having an appropriate spring function, the U-shaped band portion is opened, and the rectangular hardware is sandwiched and engaged, whereby the rectangular hardware is tightened and integrated by its own rigidity. It is.

[Operation] Hold the hanging part downward with respect to a metal piece having a rectangular cross section such as a metal piece, and open each of the band parts, and sandwich the metal piece with each of the U-shaped band parts in the opened state. I do.
Next, the entire wiring band is rotated by 90 ° to project the U-shaped band portion, engage with the hardware, and pull down. As a result, each U-shaped band portion protrudes due to its own rigidity, and tightens and protrudes the hardware to integrate with the hardware. That is, the rotation of the wiring band is also prevented by vibration or wind pressure. This operation is repeated at intervals in the projecting direction of the protruding hardware to mount the wiring ring on the protruding hardware. As a result, the hanging portions of the wiring rings protrude and are aligned along the longitudinal direction of the hardware, so that a wiring path is formed for each hanging portion to pass through the drop wire and to be supported.

[Embodiment] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

The wiring ring is formed of a rigid steel wire having a predetermined length, for example, a steel wire 1 having a diameter of about 2 mm cut into a predetermined length.

Using the cut steel wire 1 as a raw material, as shown in FIGS. 1 and 2, the steel wire 1 is first bent in the middle in the longitudinal direction into a loop in the opposite direction, and a lead wire or the like is inserted into the loop. The hanging part 2 to be supported is formed. Then, as shown in FIG. 3, the steel wires 1 on both ends of the hanging portion 2 are bent twice at right angles twice in opposite directions so as to suspend the hanging portion 2 on the protruding hardware 3 as a rectangular metal. The U-shaped band portions 4 which are opposite to each other are formed. Here, the U-shaped band portion 4 is bent at a portion where the lengths of the opposite sides of each U-shaped band portion 4 are equal, and the U-shaped band portion 4 is bent at the U-shaped portion with respect to the portion of the steel wire 1 forming the hanging portion 2. The part forming the band part 4 is bent in a direction in which the part becomes the same plane. Thereafter, the tip of the portion forming each U-shaped band portion 4 (both ends of the steel wire 1 before forming the suspension portion 2)
Is further bent at a right angle to form a locking portion 5 for preventing rotation. Then, a guide portion 6 is formed by bending a portion on the distal end side of the locking portion 5 outwardly at an obtuse angle in a rectangular shape formed by the U-shaped band portion 4 so as to protrude and improve the engagement with the hardware 3.

The wiring ring 7 thus formed has a proper spring function in the open leg direction and the torsion direction.

The mounting procedure of the wiring ring 7 is shown in FIG.
For example, the following is performed.

First, the hanging part 2 is held downward with respect to the protruding hardware 3, each of the band parts 4 is opened, and the protruding hardware 3 is sandwiched in a state where the legs are opened. Next, the entire wiring band is 90
After the rotation, the guide portion 6 and the locking portion 5 protrude, engage with the hardware 3, and are pulled down. As a result, the U-shaped band portion 4 protrudes due to its own rigidity, and tightens and protrudes the hardware 3 to be integrated with the hardware 3. That is, the projection 3 is always protruded by the vibration and the wind pressure and is integrated with the hardware 3 without rotating.

This work is repeated at intervals in the longitudinal direction of the protruding hardware 3 to attach the wiring ring 7 to the protruding hardware 3. As a result, the hanging portions 2 of the wiring rings 7 protrude and are aligned along the longitudinal direction of the hardware 3, and the hanging portions 2 pass through the drop wire 8 and are supported to form the wiring path 9.

Of course, it is also possible to apply a rubber coating to the outer peripheral surface of the hanging portion 2 so as to protect the jacket of the drop wire. The steel wire 1 is plated or formed of a stainless steel wire 1 and is configured to cope with rust and the like.

[Effects of the Invention] As is clear from the above description, according to the invention, the following excellent effects are exhibited.

(1) One-handed and one-touch operation can be performed on metal parts with a rectangular cross section, such as protruding metal parts, so that the function of interworking communication lines and the like can be greatly improved. In the state where it is drawn through, it can be prevented from rotating with respect to the rectangular hardware due to vibration or wind pressure.

(2) It is excellent in manufacturability and can be formed at low cost.
