Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is designed to wrap around the outer periphery of tires when driving on snowy or frozen roads. This relates to a ladder-type tire skid device that is used with a tire.

0002

[Conventional technology]

As this type of tire skid device, those illustrated in FIGS. 3 to 5 are known (for example, (See Special Publication No. 57-53201). This tire skid device 11 is made of rubber, synthetic resin, etc. A large number of substantially groove-shaped grooves formed of an elastic material so that they can be attached to the outer periphery of the tire T. A non-slip member 12, and each end of the non-slip member 11 is connected to a rope 13 (rope, wire, etc.). , consists of a large number of hooks 14 that connect the anti-slip member 12 and the cable 13. The inner surface 15 of the ear T that comes into contact with the tread contact surface TT is a flat surface.

0003

[Problem that the idea aims to solve]

By the way, when the above-mentioned conventional anti-skid device is attached to a tire, the tire tread surface is It is not parallel to the tire axis, but has an arcuate shape, so it is particularly difficult to A gap is created between the shoulder part and the shoulder part of the anti-slip member, and this gap Snow, ice, etc. can get into the tire and cause misalignment between the anti-skid member and the tire, causing the anti-skid device to There is a problem in that the original anti-slip function cannot be fully demonstrated.

0004 This invention was made in view of the above-mentioned circumstances, and its purpose is to There is no gap between the tire and the anti-slip member, preventing the intrusion of snow, ice, etc. To provide a tire skid device capable of eliminating misalignment between a tire and a tire.

[0005]

[Means to solve the problem]

In order to achieve the above object, the present invention takes the following technical measures. That is, the present invention uses elastic materials such as rubber and synthetic resin to cover the outer circumferential surface and both sides of the tire. A non-slip member with an inner shape and a required width that can fit the surface is formed, and multiple non-slip members are Connect each end to the cable using connecting hooks at appropriate intervals and attach it to the tire. In the tire skid device, the anti-slip member has at least an inner surface, especially the tire. The radius of curvature in the axial direction of the contact surface with the tire tread surface is The radius should be the same as or slightly smaller than the radius, and substantially the entire inside surface of the anti-skid member should be on the outside surface of the tire. It is characterized by being in contact with each other.

[0006]

[Effect]

According to the present invention, when the anti-skid device is attached to the tire, the tire tread of the anti-skid member The radius of curvature in the axial direction of the inner surface of the crown, which is in contact with the tire tread surface, is The radius of curvature in the axial direction is the same or slightly smaller, so the anti-slip member can be attached to the rope by the cable. When tightened, almost the entire inside surface of the anti-slip member comes into contact with the outside surface of the tire, especially the shoulder area. There is no gap between the two parts.

[0007]

【Example】

Hereinafter, embodiments of the present invention will be described based on the drawings. 1 and 2 show an embodiment of the present invention, in which the tire skid device 1 is made of rubber, synthetic resin, etc. Numerous anti-slip members 2 made of elastic material and tightening cables made of rope etc. 3,3, and a number of connecting hooks 4 that connect both ends of the anti-slip member 2 to the cables, respectively. ing.

[0008] The anti-slip member 2 covers the outer peripheral surface (tread surface TT) of the tire T and both side surfaces following this. It has an inner surface shaped to fit perfectly on the TS (shoulder part) and has the required width. The thickness and width of both ends 2b and 2c are the same as the tire tread surface TT contact area, that is, the crown. These are successively larger than the main part 2a. Then, as shown in Fig. 2, the anti-slip member 2 The axial radius of curvature RN of the crown inner surface 5 is the axial curvature of the tire tread surface TT. The radius of curvature of the inner shoulder part, RS, is the same as or slightly smaller than the radius of curvature of the tie. The radius of curvature of the shoulder part of Ya-T is made the same as that of the shoulder part. Therefore, tie the anti-slip member 2. When attached to the tire T, its entire inner surface contacts the outer surface of the tire T and fits.

[0009] In addition, a core material (not shown) is buried inside the anti-slip member 2, and the anti-slip member 2 Core metal (not shown) is embedded around the hook engagement holes 6, 6 provided in the ends 2b, 2c, Both ends of the core material are connected to a metal core. In addition, the crown portion 2a of the anti-slip member 2 is , spike pins can be buried. Both ends of the cable 3 are connected by a tightening device (indicated by reference numeral 16 in FIG. 3) to form an endless ring. The tightening force is adjustable.

0010 The connecting hook 4 has both ends of a metal bar bent in the same direction in a substantially U-shape, Fit the upper end 4a into the hook engagement hole 6 of the anti-slip member 2, and wrap the lower end 4b around the cable 3. It is fixed by caulking, and if the anti-slip member 2 is damaged or worn and needs to be replaced, Remove the end 4a from the non-slip member 2 and engage it with a new non-slip member 2 for easy replacement. It's starting to sound like this.

[0011] According to the above embodiment, when the anti-skid device 1 is attached to the tire T, the clamp of the anti-skid member 2 The inner surface 5 of the winding part fits the tire tread surface TT, and the following shoulder - part is also tightly sealed with the shoulder part of the tire T without creating a gap. wear it. Therefore, snow or ice is prevented from entering between the anti-skid member 2 and the tire T. Since the anti-slip member 2 does not shift, the anti-slip function can be fully demonstrated.

【Effect of the invention】

As mentioned above, this invention uses elastic materials such as rubber and synthetic resin to cover the outer circumferential surface of the tire. and a non-slip member with an inner shape and required width that can be adapted to both sides, and Connect each end of the stopper member to the cable with a connecting hook at appropriate intervals, and attach it to the tire. In a tire skid device that can be mounted, at least the inside surface of the anti-slip member is In particular, the radius of curvature in the axial direction of the contact surface with the tire tread surface is The radius of curvature in the direction is the same or slightly smaller, so that almost the entire inner surface of the anti-slip member is covered with the tire. Since it is characterized by being in contact with the outer surface, the inner side of the non-slip member The entire surface of the tire fits snugly against the outer surface of the tire, leaving no gap between it and the outer surface of the tire. Therefore, snow, ice, etc. do not get in, and the anti-slip member does not shift, so it has sufficient anti-slip function. In addition, the thickness of the shoulder part of the anti-slip member can be made thinner. This reduces heat generation while driving, improves the durability of the anti-skid device, and improves driving stability. You can aim for the top.
