Description

[Detailed description of the invention] <Industrial field of application> The present invention relates to a hose clamp used to fasten hoses such as rubber hoses, and more specifically, to a structure for holding the hose clamp in an enlarged diameter state. Regarding.

<Prior art and its problems> The conventional hose clamp shown in FIG. 1 has been used. That is, the hose clamp 1
is composed of an annular clamp part 2 and grip parts 3 and 4 that stand up after extending opposite ends of the annular clamp part 2 and intersecting each other, and the grip parts 3 and 4 of the hose clamp 1 The diameter of the annular clamp part 2 is expanded by bringing the clamp parts close to each other, and after the clamp part 2 is inserted into an object to be clamped in the expanded diameter state, the clamp part 2 is fastened by its own elastic force by releasing the expanded diameter state. . However, when using such a fastening method, it is necessary to work on each hose clamp while holding the grip part with a jig, which requires a lot of work. In some cases, it was necessary to obtain the expanded diameter again, which was particularly inconvenient. For this purpose, hose clamps such as those illustrated in FIGS. 2-3 were provided. That is, in the device disclosed in Japanese Utility Model Publication No. 52-14511, the grip portions 3, 4 are attached in advance to the gripping tool 5 formed in a U-shape as shown in the figure.
was installed, and the fastening position could be corrected when the clamp part 2 was in the expanded diameter state. When using the clamping tool 5, a jig is used to pull out the U-shaped clamping tool 5 after positioning it with respect to the object to be clamped, but in the case of the one shown in the figure, the jig is clamped from both sides. In order to pull it out, the clamp part 2 itself was subjected to diameter reduction pressure, and an abnormal pulling force was required. Moreover, the above-mentioned diameter reduction pressure causes stress to be concentrated on the curved portion 5a of the clamping tool 5, which inevitably requires rigidity in the curved portion 5a itself.

Another known example is a hose tightening fitting disclosed in Japanese Utility Model Publication No. 51-40088, but since this known hose tightening fitting does not have a grip part, it can be expanded in diameter using commercially available pliers, etc. It is difficult to do so, and there is the disadvantage that a tool specially made for this purpose is required, and it is not possible to maintain a steady expanded diameter state without the tool.

In view of the above-mentioned problems, the present invention aims to provide a structure in which the expanded diameter state of the hose clamp can be maintained with a simple structure, and which can be easily handled with commercially available pliers or the like.

<Means for Solving the Problems> In order to achieve the intended purpose, the present invention has an annular shape in which one end having a slide hole and the other end having a width that allows entry into the slide hole intersect with each other. The hose clamp is composed of a clamp part made of an elastic band material, and grip parts protruding from both ends of the annular clamp part in the centrifugal direction of the clamp part, and the annular clamp part is expanded in diameter. In the structure for holding the clamp in this state, the diameter of the annular clamp part is expanded so that the inner surface of the grip part at one end of the clamp part and the inner surface of the grip part at the other end of the clamp part face each other with a gap between them. A plate material is interposed in the gap between the grip portions facing each other, and the inner surface of each grip portion is in pressure contact with both surfaces of the plate material.

<Example> Hereinafter, an example of the hose clamp according to the present invention will be described with reference to the drawings.

4 to 6 are views showing an embodiment of the hose clamp 10 according to the present invention, and FIG. 4 shows the state when the hose clamp 10 is in a free state and an object to be clamped is fastened. 5 and 6,
FIG. 6 is a perspective view when the plate is inserted between the grip portions and expanded in diameter.

That is, the hose clamp 10 is defined by a thin metal plate made of an elastic material, and the clamp portion 11 is formed by a band material having approximately the same width and a predetermined length.
Then, grip portions 12, 12 are formed at both ends of the clamp portion 11, and then the grip portion 11 is formed into an annular shape. The grip portions 12, 12 are located at both ends and extend in opposite directions, one being two parallel grip portions 12 having a slide hole 13 in the center along the strip, and the other grip portion 12 extending in opposite directions. Two grip portions 12 having a width to be inserted into the hole 13 are formed.
The grip portions 12, 12 are configured to stand up in a manner that crosses each other toward the outside.
That is, the hose clamp 10 is completed in such a manner that the annular clamp portion 11 is reduced in diameter by its own elastic force and the object to be clamped is always clamped. Therefore, the grip portion 12 is configured to intersect with the other grip portion 12 by expanding or contracting the annular clamp portion 11 in diameter.

Next, before tightening the hose clamp 10, that is, in order to make the diameter expanded, as shown in FIGS. 5 and 6,
When the mutual grip parts 12, 12 are brought close to each other against the restoring force and the grip parts 12, 12 are released from the intersecting state, that is, when the plate material 14 is sandwiched between the opposing grip parts, the plate material 14 is held in a stable state by the pressure of the grip portions 12, 12 to reduce the diameter thereof, thereby maintaining the expanded diameter of the hose clamp. In such a state, the hose clamp 10
When the hose lamp 10 is inserted into a predetermined position of the object to be held and the plate 14 is pulled out using a suitable jig, the hose lamp 10 will reduce in diameter by its own restoring force and fasten the object to be held. The above-mentioned plate material 14 is a flat plate and its shape is not particularly limited, but as shown in the figure, there is a space 14 that can be held by a jig when an object to be held is fastened.
It is sufficient that a and 14b are defined.

<Effects of the invention> As explained above, in the present invention, in a prescribed hose clamp, the annular clamp part is enlarged in diameter,
The inner surface of the grip portion at one end of the clamp portion and the inner surface of the grip portion at the other end of the clamp portion face each other with a gap, and a plate material is interposed in the gap between the grip portions facing each other. The inner surfaces of each grip portion are in pressure contact with both surfaces.

Therefore, in the case of the present invention, it is possible to interpose the plate material between the grip parts using commercially available pliers, and once the plate material is interposed, the expanded diameter state of the clamp part can be adjusted without using tools. In this state, it is easy to fit the hose clamp around the outer periphery of the hose and to adjust the movement of the hose clamp in the longitudinal direction of the hose.

Moreover, when tightening the hose with a hose clamp, all you have to do is grasp a part of the plate material with commercially available pliers and pull it out from between the grips.
At this time, since no force is applied that would tighten the grips together, the operation can be performed easily.

Furthermore, since it is only necessary to interpose the plate material between the grip portions, the structure for holding the expanded diameter of the clamp portion is extremely simple.
