Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a metallic coupling band for fastening circular objects to be fastened.

<Prior Art> For example, a bellows-shaped rubber boot is tied to a connecting portion of a tie rod of an automobile as a dustproof cover. Additionally, various rubber ducts are connected inside the engine room. Metal bands are used to fasten these circular objects.

Conventional general metal coupling bands are made by bending both ends of the band outward in an L-shape, wrapping the band around the outer circumferential surface of the object to be tightened, and connecting the bent pieces at both ends facing each other. Then insert the screw into the screw hole drilled in the bent piece.
It is tightened with a nut.

In this case, the bent piece protrudes in the outer diameter direction and it takes time to tighten the screws and nuts.
A band is used that is fastened with one touch without using screws or nuts. Its structure is the fourth
As shown in the figure, a metal band 1 is bent into a ring shape, both ends 2 are overlapped, and both ends of the overlapped band 1 are spot-welded to the outer surface of one end 3a of an arcuate handle 3, and the end of the one end 3a is The other end 3 with the part 3b as a fulcrum
c is folded down to the outer surface of the band 1, and the other end 3c of the handle 3 is gripped by a grip 4 spot-welded to the band 1.

<Problems to be solved by the invention> The above-mentioned conventional coupling band is fastened with one touch by tilting the arc-shaped handle to the outer surface of the band, and there is no problem of protruding in the outer radial direction like a bent piece. However, since there is only one handle, a large amount of force is required to push down the handle when the tightening margin of the object to be tightened is large, which poses a problem in workability. Furthermore, if excessive force is applied to the tip 3c of the handle, there is a problem in that the handle where the both ends 3a of the band 1 are welded becomes bent. Furthermore, as shown in Figure 5, after tightening, there is a step h between the grip 4 and the outer surface of the band 1, so it is possible that the grip 4 may become deformed and loosen due to flying stones or other factors. It will be done.

<Means for Solving the Problems> In order to solve the above problems, the present invention provides a first belt portion whose length is at least approximately equal to or slightly shorter than the circumferential length of the object to be tightened; an arcuate second band portion corresponding to a part of the second band portion, and approximately 1/2 of the total length of the arcuate portion of the second band portion between both ends of the first band portion and both ends of the second band portion.
A pair of arc-shaped handles having a long length are connected to each other so as to face each other on the inside of the arc, and both handles are attached to a substantially central portion of the second band portion, with the handle end on the second band side serving as a fulcrum, and a second band portion is provided. The first parts that abut each other when brought into contact with the outer surface of the
A grip is provided at the end of the handle on the band side.

<Example> An example of the present invention will be described below based on FIGS. 1 to 3. In FIG. 1, reference numeral 10 indicates a first band portion constituting the band, and reference numeral 11 indicates a second band portion. The first belt portion 10 has a length that is at least approximately the same as or slightly shorter than the circumferential length of the object to be fastened, and the second
The band portion 11 has an arc shape corresponding to a part of the object to be tightened.

A pair of handles 12 and 13 are connected between both ends of the first band part 10 and both ends of the second band part 11 by welding or the like. The handles 12 and 13 are arc-shaped, and the total length of the arc-shaped portion is approximately 1/2 of the total length of the arc-shaped portion of the second band portion 11. The handles 12 and 13 are connected to each other as described above, facing the inner arcuate surfaces thereof.

The handles 12 and 13 are connected to the end of the first band portion 10 by wrapping the ends 12b and 13b of the handles 12 and 13, as shown in FIG.
The base portions 12a, 1 of the handles 12, 13 overlap with the arc-shaped inner surfaces of the handles 12, 13, and are also connected to the end portions of the second band portion 11.
It is preferable that the handles 12 and 13 are wrapped around each other and overlapped with the arcuate outer surfaces of the handles 12 and 13, and then joined by spot welding or the like.

Further, a grip 14 for gripping the handles 12 and 13 is fixed to the center portion of the second band portion 11 by welding or the like.

Since the present invention has the above-described structure, when both handles 12 and 13 are in an upright position, as shown in FIG. The circle of people who do this is expanding. Insert this into the outer periphery of the object to be tightened, and both handles 12,
13 at the same time toward the outer surface of the second band portion 11 in the direction of the arrow. At this time, handles 12,1
When force is applied to the tips 12b and 13b of 3, the handle 1
2 and 13 use their tips 12a and 13a as fulcrums to fall down while pulling the first band portion 10, thereby generating a tightening force.

When the handles 12 and 13 are folded down, as shown in Figure 3,
The tips 12b and 13b are abutted on the outer surface of the second band 11 and overlapped on the second band 11. By gripping both tips 12b and 13b with the grip 14, the tightening of the object to be tightened is completed.

<Effects of the invention> As described above, according to the invention, the band is divided into two members, the first band part and the second band part, and the ends of both band parts are connected by an arc-shaped handle. Since the two handles are folded down onto the second band and gripped and fixed using the grip, the two handles reduce the tightening margin by half, reducing the force applied to the handle compared to the conventional single handle. This reduces the amount by half and improves work efficiency. Further, since the point of force and the point of action when folding the handle are distributed to the same point on the base ends 12a and 13a of the two handles, there is no bending of the handle. Furthermore, since the two folded handles are fixed with a grip on the second band with their tips abutted against each other, there is no difference in the grip part, and the grip is not deformed by flying stones or other factors, and the fastened state can be maintained. It has the effect of ensuring
