Description

[Detailed Description of the Invention] The present invention relates to an anti-slip net for tires made of a rubber surface, and more particularly to an improvement of an anti-slip net in which the net body has a diagonal lattice-like mesh.

Conventionally, this type of anti-slip net made of rubber surface is easy to manufacture as it can be integrally molded with a molding die, and has a wire core, so it is strong enough for practical use and does not damage the road surface or tires. It has characteristics such as being silent and silent.

However, on the other hand, because it is a simple diagonal lattice structure, it is free to expand in the longitudinal direction, that is, in the circumferential direction of the tire, and therefore, during use (when running with the tire mounted), the centrifugal force of the tire The net body also expands in the longitudinal direction (circumferential direction of the tire) due to road resistance, creating play between the net and the tire.
As a result, there is a loss in the transmission of driving force between the tires and the road surface, uneven road resistance causes the nets to be easily worn and damaged, and the nets bulge and hit the inside of the fender. .

The purpose of the present invention is to eliminate the above-mentioned conventional drawbacks and provide an anti-slip net that can be integrated with a tire and can reliably transmit its driving force to the road surface. , on both sides in the longitudinal direction of the net body having a diagonal lattice mesh,
The structure is such that beam band portions and bent band portions are alternately and continuously formed. This beam band portion is formed by interconnecting the intersecting portions of meshes adjacent to each other in the longitudinal direction at every other point, and the bending band portion is located between the beam band portions and is bent outward from the beam band portion. It will be done.

An example of implementing the present invention will be described below based on the drawings.

In the figure, reference numeral 1 denotes a rubber net body, which is molded into a diagonal lattice shape with an angle in the longitudinal direction (circumferential direction of the tire), and has a wire core 2 built into the center. Further, the net main body 1 is formed by alternately and continuously forming beam band portions 1a and bent band portions 1b on both sides in the longitudinal direction.

The beam band portion 1a is formed by interconnecting intersecting portions a, a... of meshes adjacent to each other in the longitudinal direction at every other position,
The crossing portions a, a... are prevented from expanding excessively in the longitudinal direction, and the net body is prevented from expanding in the longitudinal direction.

Further, the bent band portion 1b is located between the beam band portions 1a, 1a... and is bent outward from the beam band portion 1a, and the connecting rings 3..., 3a... are fixed thereto, respectively.
The connecting rings 3 on one side are fixed to a tightening lobe 4 that is skewered over them.

Note that the net main body 1 is usually molded so that its longitudinal dimension is slightly shorter than the circumferential dimension of the tire, and when it is installed, it is slightly stretched due to the expansion of the bending band portion 1b, so that it can be installed on the tire without loosening. .

Furthermore, a joint band 1c is molded in the width direction at one end of the net main body 1, and at both ends of the joint band 1c there are connecting hooks 5 for connecting to a tightening rope 4 and connecting hooks 5 for connecting to a tightening band 8, which will be described later.
A is fixed.

Next, we will explain how to attach the anti-slip net of the present invention to a tire. When installing by jacking up or positioning the tire on the net body, attach the net body 1 to the tire with the tightening rope 4 inward. A, the connecting hook 5 of the joint band 1c is passed through the mesh at the other end and hooked to the tightening rope 4, and the hook 6 at the end of the rope is hooked to the rope end ring 7. Each connecting hook 5a on the other side is hung with a tightening band 8 and attached. When installing the tire after removing it from the axle, return the joint band 1c to the other end and pass it through the mesh, connect the net body 1 in a ring shape, and then attach the connecting hook 5 to the tightening rope 4. At the same time, the hook 6 at the end of the rope is hooked to the rope end ring 7, and then the tire A is put on and the tightening band 8 is hung over each connecting hook 5a.

As described above, the present invention connects longitudinally adjacent intersecting portions of the mesh at every other point on both sides of the net body in the longitudinal direction, the surface of which is made of rubber and has a diagonal lattice mesh. Since the beam band portions formed by the beam strips and the bent band portions located between the beam band portions and bent outward from the beam band portions are alternately and continuously molded, it has the following advantages.

The beam band prevents excessive elongation of the net body in the longitudinal direction, completely preventing play of the net due to centrifugal force of the tire and road resistance during use, thereby reducing the driving force of the tire. The information can be transmitted reliably to the road surface, ensuring safe driving performance, and there is no fear that the net will bulge and hit the inside of the fender.

By slightly expanding the bent band portion in the longitudinal direction during installation, the net main body can be reliably and firmly installed on the tire without loosening.

Since the number of connecting hooks is halved, both side edges of the net body are tightened along the shape of the tire, so there is no fear of it coming off, and attachment and detachment operations can be performed easily and quickly.

Therefore, the present invention achieves the intended purpose.
