BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a suspension wire cross-shaped retainer fixing device used for holding a crossing state of suspension wires intersecting at a road intersection or the like.

[0002]

2. Description of the Related Art In order to arrange a pair of suspension wires, which are formed by spirally winding strands in a crosswise direction, and to relatively position a pair of the suspension wires, for example, see Japanese Patent Registration No. 737077. It is known to hold using such a suspension line cross-shaped holding tool.

[0003]

In the above-mentioned conventional example, when the suspension lines are arranged in a crossing direction and each suspension line is arranged and held in a straight line, the suspension line cross-shaped holder (hereinafter referred to as suspension line) is used. The tensions on the left and right centering around the holding tool) are almost equal to each other, and no resultant force is generated. Therefore, the load for moving the suspension wire holding tool is not applied, and the wiring along the road crossing condition is applied. There is no problem because the condition can always be maintained and the cable can be routed on a road with a wiring space (no obstacle), but as shown in FIG. 3, one suspension line 18a is used.
Has no choice but to bend and bend the suspension wire holder A at a certain angle into a V shape (when one of the intersecting roads has a V shape, etc.), one side of the suspension line 18a (electric pole D). ) To the other suspension wire 18b on the inner corner side, and when the cable C is wired to the telephone pole D ₁ , the suspension wire 1
Since 8a tends to become direct as shown by the broken line 18 in the figure, when this force acts on the suspension wire holder A in the above-mentioned inner angle direction, and when wind pressure is further applied to this, the metal fitting is attached to the suspension wire 18b. Therefore, the cable C is routed at a position off the road, which may cause damage to the fittings or standing trees and disconnection.

At present, there is no means for effectively solving the above problems.

The present invention has been devised in order to hold the suspension wire on the intersection at a predetermined position and prevent damage to the cable or the like due to the movement of the suspension wire holder.

[0006]

[Means for Solving the Problems] A shape retaining ring is provided on a suspending wire cross-shaped holder that holds a pair of suspending wires by sandwiching them, and a spiral element wire bundle made of an elastic metal wire is provided around the shape retaining ring. The open annular portion is engaged, and both ends of the spiral wire bundle connected to the open annular portion are wound around one of the suspension wires configured by winding the wires in a spiral shape.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a device for fixing a suspension wire holder A according to the present invention. FIG. 1 is a longitudinal sectional view, FIG. 2 is an exploded perspective view,
FIG. 3 is a schematic explanatory view.

The suspension wire holder A includes a substrate 1 and a cylindrical presser 2.
And a U-shaped bolt 3 assembled together,
The base plate 1 is provided with a through hole 5 and an arc-shaped long hole 6 on one side of the main plate 4, and both ends of a U-shaped rod 7 are attached to the other side corresponding to the one side so that the U-shaped rod 7 can retain its shape. The ring 8 is rotatably assembled.

The pressing element 2 is constructed by providing through holes 9 and 9 corresponding to the through hole 5 and the elongated hole 6 on the circumferential side, and
The middle portion of the U-shaped bolt 3 is bent toward the screw portions 10, 10 at both ends to form a second holding gap 13 between the screw portions 10, 10.
The U-shaped central portion 12 and the screw portions 10, 10 are configured as a first holding gap 11.

FIG. 15 shows a spiral element wire bundle made of an elastic metal wire, in which the central portion is bent to form an open annular portion 16 of the shape-retaining ring 8 in which the open annular portion 16 is assembled to the substrate 1. A spiral wire bundle 1 that engages with the circumferential side and continues to the annular portion 16
Both ends 17, 17 of 5 are alternately wound around and fixed to the second suspension wire 18b formed by spirally winding wires. (The spiral wire bundle 15 thus formed is referred to as a winding grip in the industry, and is generally used as a tensioning tool for fixing a suspension wire or a branch line to an electric pole.) This suspension wire holder A is in an intersecting state. To assemble the two suspension lines 18a and 18b, the U-shaped central portion 1 is provided on one side (interior corner side of the first suspension line 18a) of the intersection of both suspension lines of the upper second suspension line 18b.
2, the U-shaped bolt of the suspension wire holder A is positioned upside down, and the second suspension wire 18b is inserted between the screw portions 10 and 10 and rotated toward the opposite side of the intersection of the suspension wires to rotate both screw portions 1
By passing 0 and 10 under the first suspension line, the second suspension line 18b is provided in the second holding gap 13, and the first suspension line 1 is also provided.
8a are respectively hooked in the first holding gap, and further rotated until the second suspension wire 18b on the opposite side is also inserted, and thereafter, the screw portion 10, which protrudes onto the second suspension wire 18b on the opposite side,
The through hole 9, 9 of the presser 2 is inserted into
The substrate 1 is assembled to the V-shaped bolt 3, and the screw portions 10 and 10 projecting from the through holes 9 and 9 are assembled to the board 1 at the through hole 5 and the long hole 6, and the screw portion 10 projecting from the through hole 5 and the long hole 6. 1
The first and second suspension lines 18a and 18b are held in a crossed manner by screwing nuts 14 and 14 into 0, and described on the peripheral side of the shape-retaining ring assembled to one side of the substrate 1. To engage the open annular portion 16 of the spiral wire bundle 15,
Connect both ends 17, 17 of the spiral wire bundle 15 to the second suspension wire 18b.
Alternately wound around, then the nut 1 of the suspension wire holder
4 and 14 are finally tightened and fixed.

The suspension wire 18 of the suspension wire holder A as described above is used.
In assembling to a, 18b, only the second suspension wire 18b which is wired in a straight line is stretched with a predetermined tension in advance, and the first suspension wire 18a which is bent and wired is in a state where no tension is applied, The work can be smoothly performed by assembling and fixing the suspension wire holder A at the intended intersection point by the above-described procedure and then suspending the suspension wire with a predetermined tension.

Therefore, the first suspension wire 18a and the second suspension wire 18
When the angle formed by b is asymmetrical with respect to the second suspension line 18b, only the first clamping gap 11 with respect to the first suspension line 18a of the U-shaped bolt or the second clamping gap 13 with respect to the second suspension line 18b, respectively, is a space allowance. The suspension wire holder A as a whole is forced to change the angle when viewed from the left or right, and the orientation of the substrate 1 is the orientation of the second suspension wire 18b (stretching direction).
In such a case, the substrate 1 is appropriately rotated around the through hole 5 using the arc-shaped elongated hole 6 provided on one side of the main plate 4 so as to correspond to the second suspension line 18b. Just do it. (If the mounting of the substrate 1 is turned upside down depending on the rotation direction, it can be mounted on either the left or right side.)
The outer diameter spiral pitch of a and 18b and the inner diameter spiral pitch of the wire bundle 15 are made equal.

Further, since the spiral wire bundle 15 is publicly known as disclosed in, for example, Japanese Patent Publication No. 34-9672, detailed description thereof will be omitted.

[0014]

[Effect of the Invention] Since the present invention is configured as described above,
This is a practical structure with a simple structure that can effectively fix the suspension wire cross-shaped holding tool, the mounting work is easy, and any bending wiring situation can be dealt with.
