Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-slip device mounted on a tire for preventing slipping when an automobile runs on a snowy road surface.

[0002]

2. Description of the Related Art Conventionally, as an anti-skid device for a tire, there is a tire chain in which chains are connected like a ladder. However, this is not preferable due to intermittent impact during running, and especially when running on a dry road surface. There was a drawback that this impact was so great that I could not drive. As a countermeasure against this, there is also a method of covering the outer circumference of the tire with a mesh-like tire slip band formed of synthetic resin, but in this case, the impact is small during running, but the mold is large due to integral molding, and the tire size There is a drawback that the manufacturing cost is high because the mold is different for each.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tire anti-skid device that has less impact during running, is inexpensive to manufacture, and is easy to adjust to changes in tire size.

[0004]

According to the present invention, as shown in FIG. 1, a part of the filament 3a is made of a synthetic resin in a mesh shape so as to obliquely intersect the rotation axis of the tire 1, and The linear portion of one side edge along the outer periphery of the tire 1 engages with the back side 2 of the tire so that the linear portion of the side edge is a back side short-circuit piece (not shown).
The tire slippery piece 3 which is connected shorter than the central portion and which can be mounted along the arc surface of the tire outer circumference at an arbitrary angle, and the tire slippery piece 3 are connected in a plurality of strips corresponding to the outer circumference of the tire 1. And a second connecting tool 6 for connecting both ends of a tire slip band 5 formed by connecting a plurality of tire slip pieces 3 into an endless tire slip band. And elasticity for pulling the tire front side 7 of the plurality of tire anti-slip pieces 3 endlessly connected to cover the outer circumference of the tire toward the center of the tire 1 to bring the tire anti-slip pieces 3 into close contact with the outer circumference of the tire 1. A gist of a tire anti-skid device is characterized in that each of them is provided with a fastening tool 8 made of a material.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the structure of an embodiment of the present invention will be described with reference to FIGS.
Explained by. A reticulated flexible tire anti-slip piece 11 formed of a synthetic resin such as polyurethane, in this case, the tire 1.
2 Tire slip piece 1 formed to have a length of approximately 1/4 of the outer circumference
On the surface of 1, the head of the spike-shaped spike 13 protrudes,
The back side short-circuit piece 15 of the tire anti-slip piece 11 located on the back side 14 of the tire 12 and attached to the tire 12 is formed by partially cutting off the net portion 16 as shown in FIG. Boss portion 17 and boss portion 18 formed on the net portion 16
The back side short-circuit piece 15 of the tire anti-slip piece 11 is formed shorter than the front side 20 by swaging studs (not shown) through the holes 19 formed in the boss portions 17 and 18.
As is apparent from FIG. 2, the boss portion 1 of the back side short-circuit piece 15
7 and the boss portion 17 are separated from each other by the distance between the boss portion 18 and the boss portion 1.
Since it is formed to be shorter than the distance between the tires 8, the back side of the tire slipping piece 11 shrinks shortly when caulking.

[0006] In this case, four pieces of the tire anti-slip pieces 11 thus formed are prepared in accordance with the size of the tire 12,
Holes 21 formed in each corner of both ends of the tire anti-slip piece 11
4 pieces of tire slipping pieces 11 with the ring 22 passed through
To form a tire non-slip belt 23, and cover the tire anti-slip belt 23 thus formed with the back side short-circuit piece 15 positioned on the back side 14 of the tire 12 to prevent tire slippage. The band 23 is detachably connected to the holes 21 at both ends thereof through the C-shaped rings 24 to form the endless tire slip band 23. In this state, the back short-circuit piece 15 of the tire slip band 23 engages with the back side 14 of the tire 12, and the tire slip band 23 does not move to the front side 25 of the tire 12.

Therefore, in this state, a C-shaped ring 26 is fitted to each mesh of the front side 20 of the tire slip band 23 (see FIG. 6), and each ring 26 is communicated with each other to form a strong elastic rubber band. When the fastener 27 is applied, each tire slip piece 11
Are strongly attached to the tire 12 while being connected to each other.

That is, since the tire anti-slip pieces 11 are formed such that the filaments forming the mesh portion 16 intersect the rotation axis of the tire 12 obliquely, four tire anti-slip pieces 11 are connected. The endless tire non-slip belt 23 can expand and contract in the axial direction and the width direction. Therefore, when the tire non-slip belt 23 is attached to the tire 12 and the rubber band fastener 27 is hung,
The tire non-slip belt 23 extends in the width direction and contracts in the axial direction, and is firmly attached to the tire.

Although the shape of the tire changes between when the vehicle is stopped and when the vehicle is running, the tire slipping piece 11 is capable of expanding and contracting in the axial direction and the width direction. The tongue 23 firmly bites into the tire 12, and the mounted state of the endless non-slip belt 23 to the tire 12 does not loosen when the vehicle travels. Further, since the tire anti-slip member 11 can expand and contract in the axial direction and the width direction, the tire anti-slip belt 23
The tire can be mounted on the tire 12 by extending the tire non-slip belt 23 in the axial direction, and the mounting work is also simplified.

The shape and size of the mesh of the mesh portion 16 are
It may be the same or different. For example, the mesh of the central portion in contact with the road surface is enlarged, and the line of that portion is the same as the line of both ends of the tire slipping piece 11 with respect to the rotation axis of the tire. You may make it parallel. Further, in the central portion of the net portion 16 that is in contact with the road surface, the slip may be provided by deforming the shape of the line, such as providing unevenness on the line. The C-shaped ring 26 is an S-shaped ring 2 as shown in FIG.
It may be 6 '. When running, the distance between the tire slip pieces 11 is relatively short, so there is no impact unlike the conventional ladder-shaped tire chain, and the tire 1
The size change of 2 can be sufficiently dealt with by changing the distance between the tire slip pieces 11 by the length of the ring 22, and the price of the tire slip device can be reduced.

The fastener 27 is a ring 26 as shown in FIG.
In addition to being able to hang on each side of the mesh through the ring, it can also be hung on the hole 28 formed at the intersection of the mesh through the ring 26 as shown in FIG. In addition to the rubber band as the fastening tool 27, it may be shaped like a rubber band and hung between two points at each opposing position. Further, the tire slipping pieces 11 are two or more kinds having different lengths. Tire 1 by combining
It is possible to sufficiently cope with a large change in the size of item 2.

[0012]

Industrial Applicability The present invention reduces the cost of a tire antiskid device by connecting a plurality of synthetic resin tire anti-slip pieces having a length obtained by arbitrarily dividing the tire outer circumferential length and covering the tire with the tire anti-skid device. In addition, it is possible to reduce the impact during running while sufficiently coping with the change in tire size. Further, the tire anti-slip piece is made of a synthetic resin in a mesh shape so that a part of the filament crosses the rotation axis of the tire at an angle, and is stretchable in the axial direction and the width direction, It is possible to improve workability when the tire slip pieces are connected and attached to the tire. Also, after mounting, pulling the tire front side of the tire anti-slip piece toward the center of the tire with the fastener will cause the tire anti-slip piece to expand in the width direction and contract in the axial direction, so the fastener will provide a strong bond to the tire. Even when the tire is deformed while the vehicle is running, the tire slipping piece is deformed according to the deformation, and therefore the tire slipping piece is not loosely attached when the vehicle is running.
