Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a tire skid device.

(Prior art) Non-metallic anti-slip devices for automobile tires include those shown in Japanese Patent Publication No. 18648-1981.
In this product, a net serving as a reinforcing core material is covered with rubber.

Spikes are provided at the intersections of the meshes to increase resistance to slippage in the axial and circumferential directions of the tire.

However, in the above conventional method, the spike tool is caulked to the intersection of the mesh so as to embrace the intersection.

For this reason, the spike tool was easily removed. or,
Since the entire spike tool is exposed, the spike tool is susceptible to rust and is also susceptible to hitting objects such as stones, and due to these factors, there is a problem that the spike tool is easily broken.

In order to solve this problem, various anti-slip devices have been proposed in which substantially the entire spike device is covered with a covering material. However, in the past, a reinforcing core material was avoided and spikes were provided instead.

(Problems to be Solved by the Invention) For this reason, in the above-mentioned conventional method, the spikes easily come off, and it was necessary to provide the covering material with a special attachment portion for the spikes.

In addition, if a spike device is provided and the reinforcing core material is covered with a covering material, if the spike device is to be provided at the attachment part, the spike device must be held in a predetermined position by a holding means during the above-mentioned covering. Therefore, there is a problem in that the non-slip device cannot be manufactured easily.

In addition, after the reinforcing core material is covered with the covering material, when inserting the spike tool into the spike tool attachment hole of the attachment part, it is necessary to push the attachment hole wide and drive the spike tool, In this case as well, there is a problem that the non-slip device cannot be manufactured easily.

An object of the present invention is to provide a tire skid device that can solve the above problems.

(Means for Solving the Problems) In order to achieve the above object, the present invention is characterized in that the reinforcing core material 7 is covered with a covering material 8 made of a non-metallic elastic material. in a shape and equipped with a spike tool 15,
The spike tool 15 is formed into a ring shape that surrounds the reinforcing core material 7 at appropriate intervals, and is engaged and held by the reinforcing core material 7 in an externally fitted manner, and is substantially entirely covered with the covering material 8. The covering material 8 is also interposed between the reinforcing core material 7 and the spike device 15, and the spike portion thereof is made to protrude from the road surface side of the covering material 8, and furthermore, the spike device 15 is elastic in the radial direction of the tire. The point is that it is formed to be deformable.

(Embodiment) Hereinafter, a first embodiment of the present invention will be described based on the drawings. 1 is a tire, 2 is a tread portion of the tire 1,
3 is a shoulder portion of the tire 1, 4 is a rim, and 5 is a disk.

Reference numeral 6 denotes a band-shaped anti-slip device which is removably wound around the outer circumferential surface of the tire 1, and has a mesh-like structure by covering a reinforcing core material 7 with a covering material 8.

As the reinforcing core material 7, synthetic fibers or natural fibers such as polyester, nylon, or rayon are used. The reinforcing core material 7 itself may or may not be woven into a mesh shape by means such as lattice weaving.

Rubber is generally used as the covering material 8, but plastic or other non-metallic materials may also be used.

The anti-slip device 6 consists of a main body part 9 located on the tread part 2 of the tire 1 and a pair of side parts 10 located on both sides of the tire 1.

A large number of hexagonal anti-slip meshes 11 are arranged in the circumferential direction of the main body 9, and a pair of opposing sides of each anti-slip mesh 11 is arranged in an axial direction parallel to the axial direction of the tire 1. The other two pairs of opposing sides of the anti-slip mesh 11 are sloped portions 13 that are sloped in both the axial direction and the circumferential direction of the tire 1. The axial portions 12 of adjacent anti-slip meshes 11 are shared.

Coil-shaped spikes 15 are fitted onto the reinforcing core members 7 on both sides of the axial portion 12 and held therein. In this case, both ends of the spike tool 15 may or may not be fixed to the reinforcing core material 7. Since the spikes 15 are coiled, they can be elastically deformed in the radial direction, and therefore can be elastically deformed in the radial direction of the tire 1. Further, although the spike tool 15 is almost entirely covered with the covering material 8, the spike tool 15 is covered with the covering material 8.
A part of each ring-shaped portion 5 is made to protrude from the road surface side of the covering material 8 as a spike portion.

The spike tool 15 is installed in the following manner.

That is, when putting the reinforcing core material 7 into the mold and covering it with the covering material 8 made of rubber, the spikes 15 are fitted onto the reinforcing core material 7 and held in engagement. 7 and the spike tool 15 are covered with the covering material 8.

In this way, since the spike tool 15 is engaged and held by the reinforcing core material 7, the spike tool 15 is difficult to come off, and moreover, the covering material 8 prevents the spike tool 15 from coming off.
When covering the reinforcing core material 7 and the spike tool 15,
A means for holding the spike tool 15 is not required, the non-slip tool 6 can be manufactured easily, and there is no need to provide a special attachment part for the spike tool 15 on the covering material 8.

On both sides of the hexagonal anti-slip mesh 11, there are a substantially hexagonal engagement mesh 16 and a substantially pentagonal non-engagement mesh 1.
7 are arranged in succession in the circumferential direction alternately. Anti-slip mesh 1 in the engaging mesh 16 and the non-engaging mesh 17
The side portion on the first side is constituted by an inclined portion 13 of the anti-slip mesh 11. The inner portions of the engaging mesh 16 and the non-engaging mesh 17 are included in the main body portion 9, and the other portions constitute a side portion 10.

Connecting parts 18 extending in the axial direction of the tire 1 are formed at both ends of the anti-skid tool 6, and both sides of the connecting parts 18 are separably connected by a pair of connecting fittings 19, so that the anti-skid tool 6 is annular.

A pair of flexible cables 20 are made of ropes, wires, etc., and are arranged on both sides of the tire 1.
0 is attached to the outer side of the engagement mesh 16 of each side portion 10 and each side end of the connecting portion 18, respectively, with connecting fittings 2.
2 and 23. The ends of each flexible cable 20 are also separably connected to each other by a connector 24, and the flexible cable 20 tightens the engagement mesh 16 of each side portion 10 inward in the radial direction of the tire 1. By doing so, the anti-slip device 6 is held on the tire 1.

According to the embodiment configured as described above, a large number of polygonal anti-slip meshes 11 are arranged in a row in the circumferential direction on the main body portion 9 of the anti-slip device 6, and the opposing two meshes of the anti-slip mesh 11 are arranged in a row in the circumferential direction. Since the pair of side portions are sloped portions 13 that are sloped both in the axial direction and the circumferential direction of the tire 1, the anti-slip device 6 is strong against slippage in the axial direction of the tire 1, and Since the pair of opposing sides of the anti-slip mesh 11 are the axial portions 12 parallel to the axial direction of the tire 1, the anti-slip device 6 is sufficient to prevent slipping in the circumferential direction of the tire 1. It has no problems in terms of traction, climbing ability, and braking. In addition, since the main body portion 9 is equipped with spikes 15, the anti-slip device 6
is extremely resistant to slippage in both the axial and circumferential directions of the tire 1.

FIG. 6 shows a second embodiment, in which an X-shaped intersection is formed in the main body 9 of the anti-slip device 6, and coil-shaped spikes 15 are engaged at two locations near the intersection of the reinforcing core material 7. is maintained.

(Effects of the invention) As described in detail above, according to the invention, the spike tool is difficult to come off, and even though almost the entire spike tool is covered with the covering material, the spikes are not attached to the covering material. There is no need to provide a special attachment part for the tool, and the non-slip tool can be manufactured easily. In addition, the spike tool is formed in a ring shape, and is fitted onto the reinforcing core material, with an appropriate distance from the reinforcing core material, and a covering material is interposed between them, so that it can be used while driving. In addition, since the reinforcing core material and the spike tool do not rub against each other and the reinforcing core material is damaged or cut, and since the spike tool is formed to be elastically deformable in the radial direction of the tire, there is no slippage. When a load from the tire is applied to the stop main body, the spikes are elastically deformed together with the covering material, and the ride comfort is good despite having the spikes. The present invention has the above advantages and is of great practical benefit.
