Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to an anti-skid device for tires.

(Prior Art) As a non-metallic anti-slip device for automobile tires, there is one shown in Japanese Utility Model Application Publication No. 60-127207, in which a non-slip mesh is formed in the circumferential direction on a band-shaped main body located on the tread of the tire. A flexible cable is provided in a pair of side parts located on both sides of the tire, and connecting parts extending in the axial direction of the tire are provided at both ends in the longitudinal direction of the band of the main body part. Both sides of the connecting part are separably connected by connecting fittings, so that the connecting part is provided around the tire.

(Problem to be solved by the invention) When driving with anti-skid devices installed around the tires, the anti-skid devices may float above the tires due to centrifugal force. Not only will the anti-slip function be impaired, but it will also be damaged early, resulting in poor durability, and there is a possibility that it will come into contact with the fender, making it impossible to drive.

In the conventional technology described above, since the stripes (reinforcing core material and covering material) constituting the anti-slip mesh and the connecting portions have approximately the same thickness, they tend to float due to centrifugal force at the connecting portions, and Since the metal fittings that connect the connecting portions to each other are located on the side portions, the effect of preventing the connecting portions from floating was small.

The present invention improves the rigidity of the connecting parts at both ends of the main body to suppress levitation due to centrifugal force, and also connects the connecting fittings that connect the connecting parts to each other as close to the center of the main body as possible. , the purpose is to prevent the connection part from floating.

(Means for Solving the Problems) The present invention has a belt-like main body part 9 which is located on the tread part 2 of the tire 1 and has a large number of anti-slip meshes 11 arranged in a circumferential direction, and A pair of left and right side portions 10 are located, and connecting portions 18 extending in the axial direction of the tire 1 are provided at both ends of the main body portion 9 in the band longitudinal direction, and the connecting portions 18 are connected to each other so as to be freely joined and separated. In order to achieve the above-mentioned object in the tire skid device 6 provided with a pair of left and right connecting fittings 19, the following technical measures are taken.

That is, in the present invention, the connecting portion 18 is made of strips 7 and 8 that are wider than the strips 7 and 8 constituting the anti-slip mesh 11 of the main body portion 9, and the pair of left and right coupling fittings 19 are Connecting portions 18 on each side of the pair of left and right connecting fittings 19 are provided at the connecting portions 18 in the pair of side portions 10 outside and near both sides of the tire tread portion 2, respectively.
This is characterized in that the strips 7 and 8 forming the anti-slip mesh 11 are connected to each other.

(Embodiment) Hereinafter, an embodiment of the present invention will be described based on the drawings. In FIGS. 2 to 4, 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 belt-shaped main body portion 9 located on the tread portion 2 of the tire 1, and a pair of left and right side portions 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 an axial portion parallel to the axial direction of the tire 1. 12, and 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.

In a pair of adjacent anti-slip meshes 11, a pair of inclined portions 13 are provided at each end of the axial portion 12.
are connected to each other, and this joint part 1
The details of 4 are as shown in FIGS. 1 and 5, in which the reinforcing core material 7 runs from the axial portion 12 to each inclined portion 13, and also extends between both inclined portions 13. running

As shown in Figure 6, 15 is a spike tool;
It is provided in the coupling portion 14 and consists of a disk-shaped base 15a and three upright portions 15b that are erected at equal intervals in the circumferential direction from the outer peripheral edge of the base 15a.

The spike tool 15 is connected to the axial portion 1 to be coupled.
2 and the reinforcing core members 7 on the pair of inclined portions 13 from below, respectively, and the reinforcing core members 7 are respectively disposed between a pair of adjacent upright portions 15b.

The spike tool 15 is almost entirely covered with the covering material 8, but the upper part of each standing portion 15b is covered with the covering material 8.
protrudes upward from the road surface.

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, it is engaged with the reinforcing core material 7 of the joint part 14, and the spike tool 15 is inserted together with the reinforcing core material 7. It is covered with a covering material 8.

In this way, since the spikes 15 are engaged with the reinforcing core material 7 on the axial portion 12 and the pair of inclined portions 13 to be coupled, the spikes 15 are not easily detached, and the spikes 15 are reinforced. Even though it is not fixed to the core material 7, the spike tool 15 is difficult to shift when being covered with the covering material 8, and furthermore, the covering material 8 has a special attachment part for the spike tool 15. There is no need to provide one.

By the way, substantially hexagonal engaging meshes 16 and substantially pentagonal non-engaging meshes 17 are alternately arranged in succession in the circumferential direction on both sides of the hexagonal anti-slip mesh 11. The sides of the engaging mesh 16 and the non-engaging mesh 17 on the side of the anti-slip mesh 11 are formed by the inclined portions 13 of the anti-slip mesh 11. Engagement mesh 16
The inner portion of the non-engaging mesh 17 is 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 in the band longitudinal direction of the anti-slip device 6, and both sides of the connecting parts 18 are separably connected by a pair of connecting fittings 19. The anti-slip device 6 is annular.

That is, the connecting portion 18 has stripes 7, which are wider than the strips 7, 8 constituting the anti-slip mesh 11 of the main body portion 9.
8, and the connecting fitting 19 is connected to the tire tread portion 2.
The pair of lateral parts 10 outwardly and near both sides of the
The connecting portions 1 are provided in the connecting portion 18 on both sides of the pair of left and right connecting fittings 19.
8, the strips 7 and 8 constituting the anti-slip mesh 11 are combined, and the connecting fittings 19 connect the connecting parts 18 to each other at the stiff parts.

A pair of flexible cables 20 are made of ropes, wires, etc., and are arranged on both sides of the tire 1.
Connecting fittings 22,
They are engaged via 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, pitchability, and braking.

Further, since the main body portion 9 is provided with the spikes 15, the anti-slip device 6 is extremely strong against slippage in both the axial direction and the circumferential direction of the tire 1.

In the embodiment, spikes are provided at the joints of three sides of the mesh, but spikes may be provided at the joints of four or more sides.

(Effects of the invention) As detailed above, according to the invention, the connecting portion 18 is composed of the stripes 7 and 8 that are wider than the strips 7 and 8 that constitute the anti-slip mesh 11 of the main body portion 9. Therefore, the rigidity of the connecting portion 18 is increased, and when the connecting portion 18 is fixed to the tire tread portion 2, it is prevented from floating due to centrifugal force, and the strip-shaped non-slip device 6 can be easily attached to the tire 1.

Furthermore, since the pair of left and right connecting fittings 19 are provided on the connecting portions 18 of the pair of side portions 10 on the outside of both sides of the tread portion 2 and in the vicinity thereof, the chances of contact with the ground are reduced. Regardless, floating of the connecting portion 18 due to centrifugal force can be more reliably prevented.

Furthermore, since the strips 7 and 8 constituting the anti-slip mesh 11 are connected to the connecting portions 18 on both sides of the pair of left and right connecting fittings 19, the connecting fittings 19 are connected here at the strong parts. Since the parts 18 are joined together, there is less risk of them coming apart.
