【Example】

Example 1. 1 and 2 show an embodiment of a rotation preventing jig for a simple rod according to the present invention. In the drawings, the same parts as those of the conventional example are designated by the same reference numerals, and the description thereof will be omitted.

Reference numeral 8 indicates simple rods 3a, 3b and 3
It is continuously inserted into the lateral hole 6 of c, and the simple rod 3a,
A string made of wire rope or the like that binds 3b and 3c at a time and holds them so that they do not rotate; 9 is a grip fitting that is attached to one end of the string 8 and that grips the other end of the string 8; It is a metal fitting that is attached to the other end of the cord and that prevents the end portion of the cord 8 from being frayed.

The holding metal fitting 9 is attached to one end of the string 8 and a U-bolt 12 which is inserted into the left and right bolt holes 11a of the holding block 11 and strongly holds the other end of the string 8 with the holding block 11. Is attached to the back side of the grip block 11 and is screwed to the tip of the left and right bolt portions 12a of the U bolt 12 with a set screw 13.
The fixing plate 14 is fixed so as not to come off from the 1a, and is interposed between the grip block 11 and the fixing plate 14, and the U bolt 1
2 and a spring 15 for tightening.

The grip block 11 and the string 8 of the U bolt 12
Concavo-convex portions 11b and 12b are formed at the portions where the contact is made so that the string 8 does not slip off.

Further, the projection 1 with which the end of the spring 15 is engaged with the grip block 11 and the portion of the fixed plate 14 against which the spring 15 abuts so that the spring 15 does not laterally shift.
6 are formed respectively.

In such a structure, in order to adjust the tension of the wire ropes 1a, 1b and 1c, the cord 8 is continuously passed through the lateral holes 6 of the simple rods 3a, 3b and 3c from the side of the holding metal fitting 10. Next, the grip block 11 and the fixing plate 14 are strongly gripped and the U bolt 12 is pushed up to widen the gap D between the uneven portions 11b and 12b.

Then, the other end of the string 8 is passed through the gap D,
Narrow down strongly. When the string 8 is sufficiently squeezed, the grip block 11 and the fixing plate 14 are strongly gripped and released, and the U-bolt 12 is generated by the spring force of the left and right springs 15.
Is strongly drawn into the bolt hole 11a of the fixing bolt 11, so that the other end of the string 8 is strongly gripped by the grip fitting 9. Therefore, the simple rods 3a, 3b and 3c respectively attached to the ends of the wire ropes 1a, 1b and 1c are fixed and fixed integrally and do not rotate. Therefore, the bolts of the simple rods 3a, 3b and 3c are fixed. The tension of the wire ropes 1a, 1b and 1c can be smoothly adjusted by appropriately turning the fixing nut 4 screwed to the portion.

Example 2. FIGS. 5 and 6 show another embodiment of the simple rod rotation stopping jig according to the present invention.
In the figure, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. Reference numeral 16 is a grip fitting that is attached to one end of the string 8 and grips the other end of the string 8.

The holding metal fitting 16 has a holding block 17 attached to one end of the string 8 and a large hole 1 through which the other end of the string 8 is passed at one end.
8a, a movable block 18 that is inserted into the large hole 17a of the grasping block 17, grasps the other end of the string 8 with the grasping block 17 firmly, and is attached to the back side of the grasping block 17 and is movable. The fixing plate 14 is fixed to the other end of the block 18 by a set screw 13 and fixes the movable block 18 so as not to come out of the large hole 17a of the grip block 17, and is interposed between the grip block 17 and the fixed plate 14. 1 to tighten the movable block 18
