Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tire skid device that is wrapped around and attached to a tire of a traveling vehicle.

(Prior Art) As a tire skid device for a vehicle traveling on a snowy or icy road, there is one shown in FIG. 8 (Japanese Patent Publication No. 49366/1983). This anti-slip device 21 has a wide belt-shaped wrapping body 3 wrapped around the outer periphery of the tire, and both tip edges 11A and 11B of this wrapping body 3 are connected facing each other, and is provided on the left and right side edges 9 of the wrapping body 3. The engagement member 4 is tightened by the tightening ring 5
It is configured to engage with both tip edges 11.
A and 11B are connected by passing the string member 22 through them, or they are connected via a ring-shaped connecting member.

(Problems to be Solved by the Invention) In the conventional technology, when using the string member 22, it is necessary to separately form the string member 22 and insert it into the wrapped body 3. Even when it is used, it must be formed separately and engaged with the wound body 3, which increases the number of parts and makes the connection work extremely difficult.

(Means for Solving the Problems) The present invention provides both tip edges 11A and 11B of the wrapped body 3.
A pair of tangling pieces 12A and 12B are provided in a protruding manner and are connected to each other by being intertwined with each other.
By providing this, all of the problems of the conventional techniques mentioned above can be solved.

That is, the specific structure of the problem-solving means of the present invention is characterized by the two leading edges 11A, 11 of the wide band-shaped wrapping body 3 wound around the outer periphery of the tire.
B are opposed to each other, and the tangle pieces 12A, 12B protruding from the tip edges 11A, 11B on both left and right sides are intertwined with each other, and each tangle piece 12
A tire skid device in which an engaging member 4 penetrating through the tip of the winding member 4 is engaged with a tightening ring 5, and the tire slip stopper is provided with an engaging member 4 extending through the tip of the wrapped body 3 from inside each tip edge 11 to the left and right tangling pieces 12 to the tip edge 11. The core material 7 that returns is embedded and the core material 7 is wound around the engaging member 4 attaching portion 20 of the tangling piece 12.

(Function) Wrap the winding body 3 around the tire 2 and wrap the both end edges 1
After 1A and 11B are made to face each other, when the opposing pieces 12A and 12B are intertwined, both tip edges 1
1A, 11B are connected, and the tangling pieces 12A, 12
When the engaging member 4 of B is engaged with the tightening ring 5, the connected state is maintained.

Tangled pieces 12A, 1 from the tip edges 11A, 11B
The core material 7 embedded in the interior of the core material 2B increases the strength thereof, and also wraps around the engaging member 4 provided through the tips of the tangling pieces 12A and 12B, thereby attaching the engaging member 4 mounting portion 20. Improves strength and prevents breakage.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. In the first embodiment shown in FIGS. 1 to 3, a tire skid device 1 includes a winding body 3 wound around the outer periphery of a tire 2, and a plurality of winding bodies 3 provided on the wave-shaped left and right side edges 9 of the winding body 3. It has a book engaging member 4 and a pair of left and right tightening rings 5 that are engaged with all the engaging members 4.

The wrapping body 3 is formed into a wide band shape to cover the entire tread portion of the tire 2, and has a net shape to provide an anti-slip function. This wrapped body 3
In this method, synthetic fibers such as polyester, nylon, or rayon or natural fibers are embedded as a core material 7 in an elastic body 6 such as rubber or synthetic resin, either in a linear form or in the form of a net by, for example, lattice weaving. , spikes 8 are buried in appropriate locations.

The winding body 3 has a tip edge 11 of maximum thickness at both ends thereof.
A, 11B, both tip edges 11A, 11B
are wound around the tire 2 and face each other. Tangle pieces 12A, 12B are provided protruding from both left and right (tire axial direction) ends of each tip edge 11A, 11B.
A core material 7 is also embedded within this entangling piece 12.

That is, the core material 7 is embedded in a loop shape from within each tip edge 11 to the left and right side pieces 12 and back to the tip edge 11. Hole) 20 is wound outward,
Even if the engaging member 4 is pulled, the attachment portion 20 is prevented from being damaged. Both tip edges 11A, 1
The opposing tangle pieces 12A and 12B of 1B are symmetrical and substantially hook-shaped and can be intertwined with each other, and by intertwining both tangle pieces 12, both end edges 11A and 11B are connected.

The tightening ring 5 is made of rubber or a spring and is formed into a string shape. Both ends of the string are connected by a connecting member 13 to form an annular shape. Engagement member 4 engaged with 9
By engaging with, the wrapped body 3 is pulled in the width direction and attached to the tire 2 in a tightened state.

The wrapped body 3A of the first embodiment crosses the inclined line portions 16 that are inclined with respect to the tire circumferential direction in a net shape, and forms ladder long line portions 17A at every other intersection position of the inclined line portions 16. , this ladder long line part 17
A ladder short line portion 17B is formed at the intersection between A and A. These ladder line portions 17A, 17B are along the tire axial direction and are designed to increase the slip resistance against the road surface. The ladder line portion 17A, 1
Core material 7 is also buried in 7B, and spike tool 8
is provided at the center of the ladder line portion 17A.

FIG. 4 shows a second embodiment, in which the wrapped body 3B has no ladder line portion, but has a reinforced side edge 18, and a spike tool 8 is embedded at the intersection of the inclined line portions 16. The tangle piece 12 is the same as in the first embodiment.

FIG. 5 shows a third embodiment, and this wrapped body 3C has no short ladder line part and is formed of an inclined line part 16 and a long ladder line part 17A, and the tangling piece 12 is the same as in the first embodiment. be.

In the fourth embodiment shown in FIG. 6, the wrapped body 3D is mainly formed of a long ladder line part 17A and a short ladder line part 17B, and the side ends of each ladder line part 17A, 17B are connected by an inclined line part 16. Therefore, when the entangling pieces 12 are straight and facing each other and are intertwined with each other, it is necessary to deform them so as to twist them.

The fifth embodiment shown in FIG.
A and the X-shaped inclined line portion 16 form a wound body 3E, and the tangling piece 12 is the same as in the fourth embodiment.

In each of the embodiments described above, a plurality of holes for engaging the engaging member 4 may be provided in each of the tangling pieces 12 so that the mounting position of the engaging member 4 can be adjusted freely. A hole may be formed in one of the pieces 12A, 12B through which the other is inserted, and the two pieces may be entangled in an inserted state.

If the wrapping body 3 is integrally molded from an elastic material such as rubber as in the embodiment, there is no need to use any metal fittings to connect the two end edges 11, and the entangled pieces 12 are connected to the sidewall portion of the tire 2. Since it is located at the tread portion, there is no need to particularly protrude from the tread portion and cause it to be ground quickly, and durability can be improved.

(Effects of the invention) According to the invention described in detail above, both end edges 11A and 11B can be connected by simply intertwining the tangling pieces 12A and 12B without using independent connecting parts, and the connection work is simplified. It becomes extremely easy.
Moreover, not only each tip edge 11 but also the left and right binding pieces 12 can be reinforced with the core material 7, and the core material 7 also includes the attachment portion 20 of the binding piece 12 through which the engaging member 4 is inserted. It can be reinforced to prevent damage and improve durability.
