Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an anti-slip net for tires.

(Prior Art) Conventionally, a connecting band extending over the entire length in the width direction of the non-slip net body is integrally provided at one end of the main body, and both ends of the connecting band are inserted into both sides of the other end of the non-slip net main body. There is an anti-slip net for tires provided with an annular connecting portion for latching, as shown in FIG.

This anti-slip net B has an annular connecting portion 32 at one end of a mesh-shaped anti-slip net main body 31,
32, and a straight connecting band 33 is integrally provided at the other end of the main body 31, and when installed, it is wound around the tire C and connects both ends of the anti-slip net main body 31. The fifth
As shown in the figure, both ends of the connecting band 33 are connected to the connecting portion 3.
2 and 32 and hook them to connect them.

Since the above-mentioned anti-slip net B is attached by connecting its both ends, a joint D as shown in Fig. 6 is formed at the connecting part, and a connecting band is placed next to this joint D. The central portion of the connecting band 33 is exposed, and the overlapping portions E, E of both ends of the connecting band 33 and the connecting portions 32, 32 protrude from other portions. When the connecting portion in the above state contacts the ground during driving, the overlapping portions E and E and the central portion of the connecting band 33 come into intensive contact with the road surface, and a large ground contact load is applied.

The ground load mentioned above is not a problem when driving at normal speeds, but it increases as the speed increases, and when driving at high speeds,
In addition to intense vibrations, early wear of the overlapping portions E and E and problems with the strength of the connecting band 31 occur.

(Technical Problem) A technical problem of the present invention is to reduce the ground load applied when the connecting band of the non-slip net contacts the ground in the anti-slip net having the above structure.

(Means for solving the technical problems) The means taken by the present invention to solve the above-mentioned technical problems is to provide a connecting band extending over the entire length of the anti-slip net body in the width direction at one end of the anti-slip net body; In an anti-slip net for a tire, which is provided with an annular connecting part into which both ends of the connecting band are inserted and hooked on both sides of the other end of the anti-slip net main body, the connecting band is inserted from the center part of the connecting band to both ends. It is formed so as to extend toward the opposite side of the anti-slip net body as it moves.

(Function) According to the above means, the overlapping portions of both ends of the connecting band and both connecting portions are moved to both side surfaces of the tire, and the overlapping portions do not come into contact with the ground during running, or the contact force is reduced.

Further, the contact surface with the road surface during running passes through the connecting portion of the non-slip net while continuously moving from the connecting portion side end of the non-slip net toward the connecting band side end. At this time, the ground load applied to the connecting band is distributed over the entire surface of the connecting band while moving from both ends of the connecting band toward the center.

(Effects) Since the present invention is as described above, in the installed state, the overlapping parts of both ends of the connecting band and both connecting parts are
It can be transferred to both side surfaces of the tire where there is no contact with the ground or where the contact force is small, thereby making it possible to prevent premature wear of the overlapping portion.

In addition, since the connecting strip is formed so as to extend to the opposite side of the net body as it moves from the center to both ends, the ground load generated when the connecting strip comes into contact with the road surface is lower than that of conventional slipping. Unlike a locking net, the ground load is not applied instantaneously and intensively to the connecting band, but connects by gradually transferring the ground load from both ends of the connecting band to the center of the band as the contact surface moves. Since it can be dispersed over the entire surface of the band, it can significantly improve the durability and abrasion resistance of the connecting band, and reduce the impact and noise when it touches the ground.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

A shown in FIG. 1 is an anti-slip net for tires, and the anti-slip net main body 1 with the mesh pattern shown in the figure is integrally made of a wire material 4 formed with a high-tensile core material inside. The anti-slip net body 1 is knitted and formed with connecting parts 3, 3 at one end thereof, and a connecting band 2 which is inserted into the connecting parts 3, 3 at both ends and hooked thereon is integrally formed at the other end of the main body. Furthermore, the latching fittings 6 are caulked and fixed to the respective latching portions 5 formed at predetermined intervals on both sides of the anti-slip net main body 1, and each latching fitting 6 inside the main body 1 is fixed.
A tightening rope 7 is spanned along.

The connecting parts 3, 3 are formed on both sides of one end of the anti-slip net main body 1, and are formed in an annular shape so that both ends of the connecting band 2 can be inserted into them. Further, the connecting parts 3, 3 may have any shape as long as they are annular, but the connecting parts 3, 3 of the anti-slip net A have approximately isosceles shapes as shown in FIGS. 1 and 3. It is formed in a triangular shape, and its base is located on the opposite side from the anti-slip net main body 1, so that the connecting parts 3, 3 themselves are pulled by the connecting band 2 while driving. This prevents the tire from expanding in the circumferential direction.

The connecting band 2 inserted into the connecting parts 3 and 3 is attached to the other end of the non-slip net main body 1.
It is provided over the entire length in the width direction. The connecting band 2 has both ends protruding toward the opposite side from the anti-slip net main body 1 with respect to the central part, and the entire band 2 is formed into a shallow V-shape, and furthermore, connecting parts 3 near the both ends, 3 is bent toward both sides of the anti-slip net main body 1, and at the extreme end thereof, hook holes 8, 8 for hooking the hook fittings 6' are provided. It has been done.

The above-mentioned connecting band 2 may have any other form as long as it extends to the side opposite to the net main body 1 as it moves from the center to both ends.
Like the connecting band 2' shown in the figure, the entire connecting band 2' is curved, both ends of which protrude toward the side opposite to the anti-slip net main body 1, and the bottom portions of the connecting parts 3, 3 near these ends The part that is hung,
The main body 1 may be bent in both directions.

When attaching the anti-slip net A having the above structure to the tire C, the anti-slip net A is wound around the tire C, and both ends of the connecting band 2 are connected to the connecting parts 3, 3 as shown in FIGS. 2 and 3. After inserting it from the back side into the tire C and latching it, connect both ends of the tightening rope 7 inside the tire C to tighten the inside of the anti-slip net A, and attach synthetic rubber to each latching fitting 6 on the outside of the net A. The tightening band 9 is hooked and the anti-slip net A is pressed onto the circumferential surface of the tire C.

As shown in FIG. 3, in the connecting part after installation, a substantially V-shaped connecting band 2 crosses the tread surface of the tire C, and both ends of this connecting band 2 are hooked into both connecting parts 3, 3. They are connected in a stopped state, and the overlapping parts E and E of both 2 and 3 are located relatively on both side surfaces of the tire c. As described above, by locating the overlapped parts E and E as close to both side surfaces of the tire c as possible, the overlapped parts E and E can be prevented from coming into contact with the ground, or by reducing the contact. This makes it possible to reduce wear on parts E and E.

Further, the contact surface with the road surface during running moves from the end of the non-slip net A on the connecting portions 3, 3 side toward the end of the connecting band 2 at the connecting portion of the anti-slip net A.

At this time, the ground load applied to the connecting band 2 moves from both end portions of the connecting band 2 located on the tire C tread surface toward the center, and is distributed over substantially the entire surface of the connecting band.

As described above, the anti-slip net A can disperse the ground load applied to the connecting band 2 over the entire surface of the connecting band 2 during running.
In addition, since the connecting parts 3, 3 are formed into a triangular shape as described above, it is possible to prevent the connecting parts 3, 3 from spreading during driving, and prevent slipping. This can prevent the slippage of the stopper net A and the phenomenon in which the stopper net A lifts off the tire C surface due to centrifugal force.
