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 bands 22 are hooked along the respective hooks 21 arranged in a ring on the side surface of the tire D after the anti-slip device C is installed, the tightening bands should be mutually symmetrical. By sequentially latching on the symmetrically located latching hooks 21, it can finally be attached in a ring shape, but the later the latching operation on the latching hooks 21 is done, the more the shape of the tightening band after latching changes. The closer the shape is from a polygon to a ring shape, the more tensile force is required during the latching 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 fastening bands 22 in a circular manner and to perform this operation on a plurality of tightening bands 22, especially for women who are weak.

<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. At one end of
It is characterized in that the tightening band hook on the side edge of the anti-slip device is provided with an operating groove of an appropriate depth that can be loosely inserted from the outside.

<Function> After installing the tire anti-slip device on the tire, the first
Hang the tightening band on one or more latching hooks at appropriate positions. In this state, hook the part inside the operation groove of the tightening band attachment tool to an appropriate position that is not hooked to the hook on the tightening band, and then pull the tightening band in the outer circumferential direction. The operation groove is loosely fitted along the locking hook, and the side surface or bottom of the operation groove is brought into contact with the tip of the locking hook, or the tip of the operation groove is brought into contact with the side surface of the tire. After that, when the tightening band fixture is slid toward the outer periphery so that the operating groove crosses the hook, the tightening band fixture tries to contract and restore its shape toward the inner periphery. The stop part is guided at the tip side of the fitting with the operating groove, and slides down from the fitting having an appropriate hardness to transfer to the latching hook.
It is attached to this. The latching operation of the tightening band using the operating groove of the fixture is sequentially applied to each symmetrically located latching hook.

When attaching the second and subsequent tightening bands, hook the part inside the operating groove of the fixture onto the appropriate position of this tightening band and pull it outward. Place the operating groove of the tension fixture into the latching hook. After fitting loosely along the operating groove, either bring the back side of the tip of the fitting with the operating groove into contact with the outer circumferential surface of one or more tightening bands attached in a ring shape, or press the operating groove on the side or bottom surface. is brought into contact with the distal end side of the latching hook, and from this state the fitting is slid in the outer circumferential direction to transfer the tightening band to the latching hook. This operation is sequentially applied to each symmetrically located latching hook.

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

Hook and pull the tightening band on the inside part of the operating groove of the mounting tool, and place the operating groove loosely along the latching hook from the outside, and use this principle to slide the latching hook part. The tightening band can be latched onto the latching hook by operation.
Therefore, the tightening band can be attached easily, reliably, and quickly without requiring excessive force.

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. can be done.

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

Thus, the intended purpose can be achieved.
