And mounting holes 62, 62 are formed. The other ends of the bands 3 and 3a are fixed to one of the mounting holes 62, and the other end is a free end 30. The free end 30 is configured to be insertable into and removable from the other mounting hole 62. ing.
The mounting hole 62 is not limited to the illustrated example, but may be a cutout hole formed in the mounting piece 61 from the side, or may be a projection that can be wound around the free end 30 and attached. Good thing.

Although the spacing member 3b may be the same as that of the first embodiment, the spacing member 3b in the illustrated example is used.
Are formed into a thick, rigid plate-like body, and bands 3 and 3 are provided in mounting holes 31, 31 formed in the plate-like body with a tightening interval L.
3a is slidably inserted and supported so that the positioning of the spacing member 3b with respect to the outer rod 2 can be adjusted. The contact area with the rod 2 can be increased, and the outer rod 2 can be stably supported or the posture can be corrected with the spacing member 3b.

In the fastening fixture 1 thus constructed, the bands 3, 3a are set to an appropriate length so that, for example, the inner rod 2a is supported in the tightening adjustment part 5 while being supported. While pressing the inner rod 2a against the outer rod 2, the free end 30 side of the band 3, 3a is wound around the outer periphery of the outer rod 2 as desired, and the free end 30 is connected to the other end. Each of the inserted free ends 30 is pulled and tightened using pliers or the like as shown by the dotted line in FIG. 8, and then the free end 30 is bent as shown by the solid line in FIG. Thus, the bands 3, 3a can be properly tightened and fixed while maintaining the tightened state of the outer rod 2 and the inner rod 2a.

Therefore, according to the fastening fixture 1, the bands 3 and 3a can be efficiently and freely irrespective of the size and outer shape of various fastening objects such as the outer rod 2 and the inner rod 2a. When the outer rod 2 has a large diameter or the like, the free end 30 of the band 3, 3a can be inserted into an insertion hole formed in the middle of the outer rod 2 when the outer rod 2 is large in diameter. There is such a feature that it can be tightened and fixed in the state where it is made. In fastening the bands 3 and 3a, the bent free end 3

This fastening fixture 1 can surround the outer periphery of the outer rod 2 intersecting the inner rod 2a with an appropriate tightening interval, and can clamp the inner rod 2a to the tightening adjuster 5. And a pair of bands 3, 3a formed in a loop field so as to be able to be included via the inner rod 2a, and each pair of bands 3, 3a outside the inner rod 2a are attached separately in a state where they are crossed. And a conventional rod-end bolt-type tightening adjuster 5 for adjusting the distance so that the distance can be adjusted.

That is, the tightening adjustment section 5 in the illustrated example is
An adjusting screw 9 formed with a small-diameter stepped locking portion 95 at the tip of a screw portion 91 having a screw; a mounting piece 61 with mounting holes 62, 62 screwed into the screw portion 91 of the adjusting screw 9; In a state where the bases of the pair of bands 3, 3a are crossed with each other in a side view,
One end of the band 3 is held under the washer 96 by a locking portion 95.
The other band 3a is attached to the mounting hole 62 of the mounting piece 61 in a flexible manner with an appropriate configuration.

Therefore, when the adjusting screw 9 is rotated in the tightening direction, the ends of the bands 3 and 3a are attached to the mounting piece 61 and the washer 9 respectively.
By moving away through (separating) via 6, the two loop portions are pulled, and the outer rod 2 and the inner rod 2a can be properly tightened and fixed in the same manner as in the above embodiment. In addition, it is possible to provide the fastening fixture 1 having a simple and inexpensive configuration. In this embodiment, similarly to the second embodiment, one of the ends of the bands 3 and 3a may be separately engaged with and disengaged from the mounting piece 61 and the locking portion 95.

The bands 3 and 3a may be a plastic band or a string such as a fiber rope, and the configuration of the tightening adjusting section 5 is not limited to the illustrated example. That is, the tightening adjusting section 5 may be a fixing tool for releasably connecting both ends of the band like a conventional patchon lock. In this case, for example, the hook section side of the patchon lock and the fixing section 5 may be used. It is preferable that the locking operation side for releasably locking the hook portion is provided separately at each end of the pair of bands 3, 3a, and that the bands 3, 3a themselves be formed of a relatively strong elastic member. .

In this case, the fastening fixture 1 can be easily and largely opened by releasing the locking of the fastening adjusting portion 5 at each end of the pair of bands 3 and 3a. Therefore, for example, when the rod is to be vertically mounted on the inner rod 2a framed in the horizontal direction, the tightening adjuster 5 is mounted with the tightening fixture 1 mounted on the inner rod 2a. The rod-shaped body can be easily and easily inserted into the band 3, 3a loosened through the open portion with respect to the opened band 3, 3a. The rod can be quickly mounted and fixed by the operation, and the rod can be easily removed by the reverse operation. Therefore, the fastening fixture 1 configured as described above is suitably used as a fixture for temporarily attaching a temporary tacking member such as a warning light, a diffused light, or a flag, which is temporarily attached. Can be done.
