Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a tightening device for a bondage band that can easily tighten a bondage band to an object to be tightened, such as a utility pole, without using any tools.

BACKGROUND TECHNOLOGY An operating frame is combined with a base frame having a hooking hole for hooking one end of the bondage band on the base plate, and the other side of the bondage band is attached to a rotation shaft that rotates when the operation frame is operated. A tightening device for tightening bands with one end penetrated to tighten the tightening bands to telephone poles, etc.
No. 35266 is of course known.

The tightening device described in this bulletin is assembled to the underframe by hooking one end of the tightening band to a latching hole provided in the base plate, and wrapping the other end around a utility pole etc., and attaching it to a through-hole provided on the rotating shaft. , operate the operating frame while fully tightening the bondage band, rotate the operation frame halfway forward to temporarily secure it, and then tighten the remaining length of the other end of the bondage band. After cutting with a tool such as a bench to prevent any protrusion to the outside after completion, the operation frame is further rotated forward to lock the tip to the underframe, and the tightening operation of the binding band is completed.

Problems to be Solved by the Invention According to the conventional example described in the above-mentioned publication, when cutting the extra length of the bondage band, it is necessary to remove the fingertip from the tightening device, so it is necessary to rotate the rotation shaft. It is necessary to rotate the operation frame considerably forward and bend the bondage band to some extent to temporarily secure it.

However, if this forward rotation operation is performed until the temporary fixing is firm, the operating frame will get in the way and it will be difficult to cut the extra length of the band with the tool.
Temporary tightening is performed without sufficient forward rotation, and the binding band often slips during cutting of the extra length or during subsequent final tightening, resulting in insufficient tightening.

Means for Solving the Problems The present invention was devised for the purpose of providing a tightening device that eliminates the drawbacks of the conventional example, and in order to achieve this purpose, one end of the bondage band is It is constructed by providing a temporary fixing part for temporarily fixing the other end of the binding band passed through the rotating shaft on the underframe provided with a hooking hole for hanging.

Embodiment FIGS. 1 to 3 show an embodiment of a tightening device for a bondage band according to the present invention, and A indicates a base plate 1.
This underframe is made up of a cross-sectional shape consisting of a side plate 2, 2, and a circular hole 3, at the base of the side plate 2, 2 of this underframe A.
3, and the central plate 4 of the operation frame B is provided in the circular holes 3, 3.
The parallel long holes 6, 6 provided in the side plates 5, 5 provided oppositely on both sides of the operation frame B are aligned, and the side plates 5, 5 of the operating frame B are aligned.
5, the side plates 2, 2 of the underframe A are engaged, and the rotation shaft 7, which is slightly U-shaped than the pair of parallel shaft plates 7', 7', is passed through one parallel long hole 6, and the other Rotation in which the tips of the parallel shaft plates 7', 7' protruding from one parallel long hole 6 are bent to form a through hole 8 by the underframe A, the operation frame B, and the parallel shaft plates 7', 7'. A latching hole 9 for latching one end of the bondage band a is provided on the tip side of the base plate 1 of the underframe A, and a portion of the side plate 2 near the latching hole 9 is provided with a latching hole 9 for latching one end of the bondage band a. Hang the lower part of the base plate 1, cut it horizontally inward, and temporarily fix the side 11.
By protruding, a temporary fixing portion 10 having a band insertion gap 12 is provided below the temporary fixing side 11.

Reference numeral 14 in the figure indicates a locking hole that locks into a locking protrusion 13 provided at the tip of the side plates 2, 2 of the underframe A, and the locking hole 14 is provided in the side plates 5, 5 of the operating frame B.

FIG. 4 shows another embodiment in which the upper edges of the side plates 2, 2 of the underframe A are bent inward to provide temporary fixing pieces 11, 11 to form the temporary fixing part 10. It shows.

In addition, the temporary fixing piece 1 constituting the above-mentioned temporary fixing part 10
1 does not necessarily need to be provided on both sides of the underframe, and may be provided on one side, and the shape is not limited to the illustrated example. It is okay to do nothing.

Therefore, in order to tighten the bondage band a using this product, one end of the bondage band a is inserted into the hooking hole 9 from the front side of the base plate 1, bent to the back side of the base plate 1, and attached to the base frame A. (The method of assembling the bondage band a to the base plate 1 is arbitrary.), the other end of the bondage band is wound around the telephone pole D, and the through hole 8 of the rotation shaft 7 and the temporary fixing part 10 are secured. After sequentially passing through the insertion gap 12 and pulling it strongly, bend the end toward the rotating shaft 7 side, and after locking the binding band to the temporary fastening piece 11, leave enough space so that the end of the band can all be stored in the tightener. The binding band a is rotated by cutting the long portion with a tool such as pliers, and then rotating the operating frame B and locking the locking protrusion 13 of the operation frame into the locking hole 14 of the underframe A. The bondage band a is bent and wound around the moving shaft 7 in an almost S-shape without loosening, and is tightened to the telephone pole D, and in this tightened state, the locking hole 14 of the operation frame B is locked in the underframe A. It is maintained by being locked to the protrusion 13.

Effects of the invention According to the invention, the work of cutting the extra length of the bondage band, which has tended to be insufficiently tightened in the past, can be performed with a reliable temporary fixing function, so it is possible to obtain a reliable tightening condition. After installation, there are no dangerous protrusions on the outside, making it safe and practical.
