Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is installed on the outer circumference of the tire to prevent the tire from slipping when driving on icy and snowy roads. The present invention relates to a tire anti-slip device that prevents tire slippage.

0002

[Conventional technology]

Traditionally, it has been used as a tire skid device for vehicles that is attached to the outer circumference of the tire on icy and snowy roads. The tire is equipped with an anti-slip member made of a rubber-like elastic body that is installed across the ground contact surface of the tire. There is something I learned.

0003

[Problem that the idea aims to solve]

The anti-slip member has a high rigidity at its ground-contacting part, so it does not come into close contact with the icy and snowy road surface. The adhesion is not sufficient, and braking, hill climbing, and traction performance on icy and snowy roads may not be fully demonstrated. It was. Therefore, in view of the above-mentioned problems, the present invention forms sipes in the anti-slip member to prevent slipping. By improving the adhesion of the material to the icy and snowy road surface, the tire skid device can be used to brake on icy and snowy roads and climb hills. , to improve the traction performance and ensure the crack resistance of the anti-slip member. The purpose is to

[Means to solve the problem]

The technical means taken by the present invention to achieve the above object are as follows: , a non-slip device made of a rubber-like elastic material and installed across the ground contact surface 3 of the tire 2. In a tire skid device equipped with a member 4, the ground contact surface of the anti-slip member 4 is provided with a sipes 10 are formed at appropriate intervals in the left and right direction to prevent slipping. The sipe forming portion 11 of the connecting member 4) is separated from the portion 12 on the side that contacts the ground contact surface of the tire 2. It lies in the point where it is formed.

[0005]

[Effect] On the contact surface of the anti-slip member 4 made of rubber-like elastic material, there is a support that is inclined in the left and right direction. Since the grooves 10 are formed in the left and right direction at appropriate intervals, it is a non-slip member. The rigidity of the contact area of 4 has been lowered to improve adhesion to the icy and snowy road, making it easier to use on icy and snowy roads. The braking, hill climbing, and traction performance of the anti-slip member 4 are significantly improved. Also, the anti-slip member 4 The sipe forming portion 11 is formed separately from the portion 12 on the side that contacts the ground contact surface of the tire 2. Therefore, the tire contacting part 12 of the anti-slip member 4 is replaced with the rubber of the conventional anti-slip member. Adopts a rubber material with superior crack resistance compared to other materials, so it does not slip even when Sipe 10 is formed. The crack resistance of the stopper member 4 can be ensured.

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. In Figures 1 and 2, The ear anti-skid device 1 is provided across the ground contact surface 3 of the tire 2 and around the circumference of the tire 2. A plurality of band-shaped anti-slip members 4 are arranged at appropriate intervals in the direction, and a ring-shaped anti-slip member 4 is arranged. Tension cables 6 made of ropes etc. are placed on the left and right sides 5 of the tire 2, and and connecting hooks 7 that connect both longitudinal ends of the retaining member 4 to the cables 6, respectively. has been done.

[0007] The anti-slip member 4 is made of a rubber-like elastic material, and is adapted to correspond to the contact surface 3 of the tire 2. The tire comprises a central portion 8, and left and right side portions 9 corresponding to the left and right side portions 5 of the tire 2. It is formed in a U-shape that can fit around the outer circumference of 2. The ground plane of the central part 8 has many A sipe (cut or crack-like groove) 10 is formed, and the sipe 10 extends in the left and right direction. It is formed in an inclined shape, and is spaced in the left and right direction (this space is determined by (determined by the degree of adhesion required) The adhesion of the holding member 4 to the icy and snowy road surface is said to be good, making it suitable for braking, climbing slopes, and traction on icy and snowy roads. The pulling performance is fully demonstrated. In addition, in the left and right direction of the sipe 10, The inclination angle θ is set to 5 to 30°. In other words, when the inclination angle θ=0° When the driving force is repeatedly applied to the anti-slip member 4 while the vehicle is running, the anti-slip member 4 It breaks quickly and shortens its lifespan. Also, if the inclination angle θ exceeds 30°, the circumferential It becomes difficult to bring out the driving performance in the direction, so braking with Sipe 10, hill climbing, This means that the traction performance cannot be fully demonstrated.

[0008] Furthermore, the sipe forming portion 11 of the anti-slip member 4 is formed separately from the tire contact side portion 12. The central part 8 has a two-layer structure. This is tire contact The crack resistance of the anti-slip member 4 is improved by using a side part 12 with excellent crack resistance. This is to make it happen. Note that the tire contact side portion 12 is integrally formed with the left and right side portions 9. Ru.

[0009] In this embodiment, the tire skid device 1 has two types of sipes 10 with different inclination directions. It is constructed by combining anti-slip members 4 regularly (for example, alternately) or randomly. However, it is not limited to this, and may be composed of one type of anti-slip member4, It is configured by combining multiple types of anti-slip members 4 with sipes 10 having an inclination angle θ. It's okay. In addition, the inclination angle θ or the inclination angle of the sipe 10 formed on one anti-slip member 4 The diagonal direction may be uniform or non-uniform.

[Effect of the idea]

According to the present invention, on the contact surface of the anti-slip member 4 made of a rubber-like elastic body, a On the other hand, the inclined sipes 10 are formed at appropriate intervals in the left and right direction. , the sipes 10 improve the adhesion of the anti-slip member 4 to the icy and snowy road surface, making it easier to use on the icy and snowy road. The braking, hill climbing, and traction performance of the anti-slip member 4 is significantly improved. In addition, anti-slip members The sipe forming part 11 of 4 is shaped separately from the part 12 on the side that contacts the ground contact surface of the tire 2. Therefore, the tire contact side portion 12 of the anti-slip member 4 is made of rubber with excellent crack resistance. The crack resistance of the anti-slip member 4 is ensured even when the sipes 10 are formed. This has the effect of making it possible to
