Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a tightening band attachment for a tire anti-slip device.

<Prior art> Conventionally, when attaching a tightening band, as shown in FIG. The ring-shaped rubber tightening band 22 is stretched by hand and hooked one by one, or a plurality of bands are hooked one after another.

On the other hand, the tightening band 22 has been used with a relatively weak contraction force so that it will not be difficult to operate even for women who are not very strong. However, after installation, the tightening force on the outside of the anti-slip net became weaker, and as the vehicle ran at higher speeds, there was a risk that the tightening band 22 would stretch and expand due to the centrifugal force caused by the rotation of the tires.

On the other hand, in order to eliminate the risk of the anti-slip device C rising above the tire D surface or coming off from the tire D due to the extension of the tightening band 22 as described above, the diameter is made smaller. tightening band 2 by increasing the shrinkage restoring force by changing the thickness, etc.
By increasing the tightening force of 2 and using a number of such tightening bands 22, the tightening bands 22 are prevented from stretching during driving, and the anti-slip device C is securely attached to the tire D. I tried to keep it in close contact with the surface.

By the way, when the tightening band 22 is hooked along each hook 21 located in a ring shape on the side surface of the tire D after the anti-slip device C is installed, the tightening band 2
2 are sequentially attached to the latching hooks 21 located symmetrically to each other so that the latching hooks 21 are finally attached in a ring shape, but the latching hooks 21
The later the locking operation is performed, that is, the closer the shape of the tightening band after locking is from a polygon to a ring, the more tensile force is required during the locking operation.

Therefore, when using the tightening band 22 which has a very large tightening force as described above, the tightening band 22 must be stretched by hand and hooked onto all the hooks 21 due to the strong contraction force. It is difficult to attach the belts 22 in a ring-like manner and to perform this operation on a plurality of tightening bands 22, especially in the case of a weak woman or the like.

<Technical Problem> The technical problem to be solved by the present invention is to provide a tightening band mounting device that allows the tightening band to be latched across each latching hook without requiring excessive force. Our goal is to provide the following.

<Means for solving the technical problems> The means taken by the present invention to solve the above problems is to form the fixture main body into an appropriate shape using a material having an appropriate hardness, and to form the fixture main body into an appropriate shape. It is characterized in that an operating hole is formed at one end of the anti-slip device so that the tightening band hook on the side edge of the anti-slip device can be loosely fitted and slid from the outside.

<Function> After the tire anti-slip device is attached to the tire, the tightening band is hooked to one or more hooks located at appropriate locations. In this state, hook the part inside the operation hole of the tightening band attachment tool to an appropriate position that is not hooked to the hook on the tightening band, and pull the tightening band in the outer circumferential direction. The hole is loosely engaged with the tip of the hook from the outside.

After that, when this fitting is slid in the outer circumferential direction using the tip of the hook as a fulcrum, the fitting hooking part of this tightening band, which attempts to contract and recover in the inner circumferential direction, will move toward the inner circumferential direction and the fitting hooking part will be moved toward the inner circumferential direction. It is guided to the connecting part at the tip of the hook, slides down from the fitting having an appropriate hardness, moves to the hook, and is hooked thereon. The operation of locking the tightening band through the operation hole of the fixture is sequentially applied to each of the symmetrically located locking hooks.

<Effects of the Invention> Since the present invention is configured as described above, it has the following effects.

The tightening band is hooked and pulled on the inner side of the operating hole in the mounting tool, and the operating hole is loosely engaged with the tip of the hook from the outside, and the tip of the hook is used as leverage. The tightening band can be latched onto the latching hook by a sliding operation using the . Therefore, the tightening band can be easily attached without requiring excessive force.

Since the operating hole is loosely engaged with the hook for sliding operation, the tightening band can be reliably guided to the hook and attached to the hook.

Since it is made of a material with appropriate hardness, when the tightening band is moved from the fixture to the hook by sliding operation, the tightening band can be moved smoothly and instantly with little frictional resistance. It can be moved.

Since unreasonable force is not required for the tightening operation, it can be applied to tightening bands with even stronger tightening force, thereby increasing the tightening force.
The adhesion of the anti-slip device to the tire can be further improved.

Thus, the intended purpose can be achieved.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. The illustrated tire anti-slip device is of a net type.

FIGS. 1 to 3 show a tightening band attachment A for a tire anti-slip device in which the present invention is implemented.

The fastening band attachment tool A is made of a material having an appropriate hardness, such as ABS resin, AAS resin, acrylic resin,
The fixture body is formed into a generally elongated shoe sole shape using materials such as hard polypropylene, hard polyethylene, hard polyvinyl chloride resin, FRP, etc., making it easy to hold, and an operation hole is provided on one end of the fixture body.
a ₁ has been opened.

The operation hole _a1 is formed to an appropriate size as shown in Fig. 3, and the front side is formed with an appropriate slope toward the tip, and as shown in Fig. 5, It is designed to be able to be slid by being externally inserted into the tightening band hook _b1 on the side edge of the anti-slip device B.

The size and shape of this operating hole A ₁ is the same as that of the latching hook B ₁
Selection shall be made as appropriate.

Appropriate unevenness is formed on the front side (FIG. 1) and back side (FIG. 2) of the tightening band fixture A to facilitate operation.

Note that this tightening band fixture A is not limited to the above-mentioned embodiment, and may be formed into an elongated rectangular shape, or may be made of a softer material than the above-mentioned one, etc.
Shape, thickness, material, etc. can be set arbitrarily.

Next, according to FIGS. 4 to 8, a tightening band having a strong tightening force and having elasticity is attached to the anti-slip device B attached to the tire D using the tightening band attachment device A configured as described above. 1 will be explained below.

After attaching tire anti-slip device B to tire D,
The first tightening band 1 is hooked to one or more hooks _b1 at appropriate positions (see FIG. 8). In this state, insert the tightening band fixture A into the operating hole.
Insert it into the tightening band 1 from the end side where a ₁ is located, move it in the outer circumferential direction, and do not hook the part rearward of the operating hole a ₁ of the fixture A to the hook b ₁ on the tightening band 1. Bring the tightening band into contact with the appropriate position so that it is hooked to the fixture A, then pull the fixture A slightly toward you and move it toward the outer circumference to pull the tightening band 1 (Fig. 4). Return it to the side of the tire D and loosely engage the operation hole _a1 with the tip of the hook _b1 from the outside (Fig. 5).

After that, when this fixture A is slid toward the outer circumference using the tip of the hook b ₁ as a fulcrum, the fixture retaining portion of this tightening band 1 tends to contract and recover as it moves toward the inner circumference. 101 is guided to the connecting portion between the tip of the fixture and the tip of the hook, slides down from the fixture A to the hook _b1 , and is hooked thereon (FIGS. 6 and 7). The latching operation of the tightening band 1 through the operation hole a ₁ of the fixture A is sequentially applied to each symmetrically located latching hook b ₁ , and the first tightening band 1 is attached to all the latching hooks b. ₁ and attach it in a ring shape.

Next, as shown in FIG. 9, the second tightening band 2 is similarly attached to all the hooks _b1 using the operation holes _a1 of the fixture A, so as to be attached in a ring shape.

The third and subsequent tightening bands can be attached as needed, but they can be attached to each of the locking hooks _B1 of the anti-slip device B using the operating hole _A1 of the Fixture A and using the same operating method as described above. Make sure to keep it locked.

FIG. 10 shows a tightening band 4 having a different shape from that described above, and this tightening band 4 connects an outer ring 4a and an inner ring 4b arranged concentrically to connecting arms 4c.
The outer ring 4a is configured to be hooked to each hook _b1 of the anti-slip device B. This tightening band 4 is the aforementioned tightening band 1,
By attaching the anti-slip device B last after attaching the anti-slip device B, the anti-slip device B can be attached to the tire D in a secure manner.

To attach the tightening band 4, use the operating hole _a1 of the attachment A to attach the outer ring 4a in the same manner as the attachment of the tightening bands 1 and 2 described above (see Figures 4 to 8). Perform the latching operation at each section, and attach the latches along each latching hook _b1 as shown in Fig. 11.

In addition, the above-mentioned tightening band fixture A can prevent ice, snow, etc. by forming the side surface etc. into an appropriate shape.
It may also have a function of removing frost, water droplets, etc.

In addition, in the present invention, the applicable tire slip prevention device is not limited to the above-mentioned net type, but for example, a plurality of anti-slip members that extend across the tire outer surface in the width direction are attached and fixed to connecting ropes that are arranged in parallel. However, the tightening band attachment device can also be used in a ladder-type tire skid device equipped with a hook for hooking the tightening band.
