Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a cable hanger that supports cables such as electric wires and telephone lines in the air on hanging wires such as stranded steel wires that have been stretched in advance. .

(b) Conventional technology Conventionally, this type of cable hanger was
Structures as shown in Figures 9 to 9 have been proposed and are generally widely used, but in the structure shown in Figure 7, a metal steel wire 11 is bent into a W-shape, and the central crest 1
2 is suspended across the suspension wire a, and the cables b and c are passed over the valleys 14 and 14 with cable pads 13 and 13 interposed on both sides, and both ends 1 of the steel wire 11 are suspended.
5 and 15 are fixed at the symmetrical suspension wire position a with the peak 12 in between, but there is a problem in that the overhead wire work such as adding or replacing cables is troublesome, and therefore, the original suspension wire is usually It is normally used only for overhead line construction of scheduled cables. In addition, the one shown in FIG. 8 is provided with a triangular frame 22 whose apex is the base of a hook part 21 that is hooked and locked onto a hanging wire a, and a low side frame 23 of the frame 22 is provided with two long and short zinc plates. One end of 26, 27 is fixed, and the cables b, c are wound in a U shape with the plate, and the other end 28,
29 are overlapped and folded by a C-ring 25 that is engaged by spanning between the oblique frames 24, 24 on both sides of the frame body 22, and the four overlapping pieces are integrally crimped at the tip of the folded back. However, in this case as well, as in the previous example, there are drawbacks such as the complexity of the overhead line work such as adding or replacing cables, the work being limited to the initial overhead line work, and the work of fixing the hook part 21 to the hanging wire a. What is shown in FIG. 9 is a metal steel wire 31 that forms a downward projecting part 32 whose central part is substantially orthogonal to the suspension line a, and whose both ends 33 form a symmetrical suspension line with the central part in between. The hanger body 34 is bent so that it can be locked at position a, and crushed flat parts 36, 36 are formed on the upper parts of the rising frames 35, 35 of the recessed part 32, and the central part of the band body 37 The more biased part is inserted into the oblong band body insertion hole 41 of the attachment plate 40 having the hanger body insertion hole 39 with the side opening guide groove 38 and folded back, and the folded base part is fixed with the eyelet 42. The band body 37 has a structure in which a retaining plate 40 similar to the aforementioned retaining plate 40 is fixed to each free end of the band body 37, and each retaining plate 40 connects the flat part 36 of the hanger body 34 to its guide groove The hanger body 34 is supported by the hanger body 34 by aligning and inserting it into the opening and inserting it into the insertion hole 39, but in this case, overhead line work such as adding or replacing cables is required. Although it is easy to do so, the attachment plate 40 moves laterally due to vibrations caused by external forces such as wind, and the hanger body 34
The band body can be easily released by detaching from the retaining plate 4.
Since the load acting on the zero plate is supported by an extremely small portion of the plate thickness, there were drawbacks such as weak strength.

(c) Problems to be solved by the invention The problems to be solved by the invention are to solve the above-mentioned conventional technical difficulties at once, to make it easy to attach and detach from the suspension wire, and to eliminate the need for adding cables. It is an object of the present invention to provide a cable hanger that not only facilitates overhead line work such as maintenance and replacement, but also has no fear of the band body opening due to vibrations caused by external forces, and is extremely strong in terms of strength.

(d) Means for solving the problem In order to solve the above problem, the present invention forms a flat downwardly projecting flat part in the center of a single net wire and bends both ends in opposite directions. The hanger body has a hook part that is suspended from a hanging line, and the side wall W has three folded parts to narrow the open space entrance part.
It consists of a mold hanger body and band bodies of different lengths with fitting bodies such as C-rings attached to both ends, and the downwardly projecting flat part of the hanger body is connected to the open center of the hanger body. Press-fit from the entrance part and lock in the space, press-fit the fitting body on one end side of each band body into the open entrance part on one side of the hanging body and lock in the space,
The cable is wound in a U-shape with the band body, and the fitting body on the other end side is press-fitted into the open entrance part on the other side of the hanging receiver so that it can be locked in that space, and if necessary, the hooking body can be closed. A cable hanger is provided on the folded side surface of the cable hanger, which is provided with a locking claw whose free end side protrudes from the inner part of the cable hanger, with the open entrance section serving as a knot in the central open space.

(e) Effect Next, the operation of the present invention will be explained.

Suspend the hooks at both ends of the hanger body from a pre-stretched suspension wire such as stranded steel wire, and fit one end into the open space on one side of the hanger body, which is attached to the downwardly projecting flat part of the center of the hanger body. Among the band members of different lengths that are suspended by anchoring the stopper, the upper cable is wound in a U-shape with a relatively short band, and the stopper at the other end is connected to the other end of the hanging receiver. The cable is supported by being attached to the open space, and in the same way, other cables at the lower stage are successively supported using longer band members.

(f) Example An example of the present invention will be described below with reference to drawings 1 to 6.
The configuration will be explained with reference to the drawings.

As shown in Figures 1 and 2, one rope 1
A flat downwardly projecting flat part 2 is formed in the center thereof, and both ends are bent in opposite directions to form hook parts 3, 3.
A hanger body 4 is provided to form a hanger body 4. As shown in FIGS. 3 and 4, it has three folded parts 5a, 5b, 5c, and open spaces 6a,
A side wall W-shaped hanging receiver 8 is provided with narrow inlet portions 7a, 7b, and 7c of b and 6c. And again,
Band bodies 10a and 10b of different lengths are provided at both ends with fitting bodies 9 such as C rings as shown in FIG. 5, respectively.

Therefore, the lower projecting flat portion 2 of the hanger body 4
is press-fitted from the open entrance part 7b at the center of the hanging body 8 and fixed in the space 6b, and one end side of each band body 10a, 10b is fitted into the open entrance part 7a on one side of the hanging body 8. The body 9 is press-fitted into the space 6a, and the hook portions 3, 3 at both ends of the hanger body 4 are suspended from a suspension line a, such as a steel stranded wire, which has been stretched in advance. Cables b and c are wound in a U-shape, and the fitting body 9 on the other end side is press-fitted into the open entrance portion 7c on the other side of the hanging body 8, so that it can be locked in the space 6c.

In this case, a locking claw A is provided on the folded side surface of the hanging receptacle 8, and the free end side protrudes into the inner part of the center open space 6b with the open entrance 7b as a node. When the flat part 2 of the hanger body 4 is press-fitted into the central flat part 2 of the hanger body 8 from the central open entrance part 7b of the hanger body 8, the locking claw A is folded back and pushed toward the side surface of the flat part. 2 passes through the position of the free end, the free end side naturally extends to the open space 6b side due to elasticity and completely locks the flat part 2, thereby causing the flat part 2 to move into the open space 6b.
You can restrict them from dancing inside.

(g) Effects of the invention As is clear from the above explanation, the present invention allows for quick and easy attachment and removal of the hanging wire with one touch, and also allows one fitting body of the band body to be attached to one side of the hanging support body. By removing it from the open space, overhead line work such as adding or replacing cables can be easily done.
In addition, there is no risk of the band body coming loose due to vibrations caused by wind or other external forces because its fitting body is securely supported in the open space that narrows the entrance of the hanging body. The center of gravity is stable and averaged in the Yajirobe style, and the shaking is very small. Furthermore, since the hanger is supported by the entire length of the central flat part of the hanger, the load per unit length is small and it is extremely strong and has many excellent practical values.
