2. Description of the Related Art Conventionally, in this kind of tire anti-skid device, for example, a main body of the anti-skid device wound around a tire is formed in a net shape from rubber or the like, and the road surface of the metal anti-skid device is damaged. Although it had been able to eliminate vibrations and vibrations, but because the anti-slip effect was not sufficient, spike metal fittings made of strip steel plate, such as the tire anti-slip device described in Japanese Utility Model Laid-Open No. 60-38801, were used for the net. A rubber-like anti-slip body, which is wound around and fixed to each intersection, has been invented up to now.

[0003]

However, in the above-mentioned prior art, even if it is made of non-metal, it has the above-mentioned spike metal fitting (metal material), and there is a fear that the spike metal fitting may scrape the road surface, so that the anti-slip effect is not achieved. Even if it improved, there was still room for improvement in terms of road surface protection.

The present invention has been made in view of the above problems of the prior art. The purpose of the present invention is to improve the anti-slip effect without providing any metal material and to protect the road surface. To be effective.

[0005]

In order to achieve the above-mentioned object, the technical means of the present invention is to embed a non-slip tip on the entire surface of a non-metallic anti-slip device main body or a desired position on the surface. The tip surface is exposed so as to be flush with the surface of the anti-slip tool body, and the anti-slip tip is provided with a chip body having a desired shape in a direction substantially perpendicular to the surface of the tip body, A plurality of string-shaped fiber materials that are provided inside the chip body and each upper end surface of which is exposed on the surface of the chip body, and form a gap having a desired depth from the surface to the bottom surface of the chip body. Is.

[0006]

According to the technical means described above, when the tire anti-skid device of the present invention is mounted on a tire and travels, the rubber portion surrounding the fiber material is compressed by the fiber material when pressed on the road surface to form a dent and snow. A strong grip is generated because it captures irregularities on the surface.

Further, since each one of the string-like fiber materials is independent and the surrounding area is made of rubber, the string-like fiber material moves appropriately in all directions, so that complicated irregularities on the snow and snow surface can be detected and the exposed portion on the surface. The edge effect (snapping effect) creates resistance in all directions and demonstrates stable grip performance.

Further, each of the string-shaped fiber materials that are pressed and exposed on the surface of the chip body absorbs and removes moisture, and at the same time, the space between the adjacent string-shaped fiber materials and the gaps are frozen and frozen. Suction and remove the water film on the surface.

In addition, the space between the string-shaped fiber material exposed on the surface of the chip body when the tire slip stopper is pressed and the adjoining string-shaped fiber material has an adsorbing action and adheres closely to the road surface. To do.

Further, the fibrous material exposed on the surface of the chip body scratches the road surface by the edge effect, and the fibrous material removes moisture on the road surface, and the gaps on the surface of the anti-slip chip are formed by running. Repeats opening and closing to absorb and remove moisture from the road surface.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a tire slip stopper, and the slip stopper 1 comprises a slip stopper body 2 and a slip stopper 4. It consists of

The anti-skid body 2 is made of wire, natural fiber,
A core material of a desired shape made of synthetic fiber, glass fiber, etc. is internally provided, and the whole net shape is made of natural rubber, synthetic rubber or synthetic resin (vinyl chloride resin, polyurethane, etc.), etc. In that case, both ends 2 ',
2'is shown by abutting and connecting (FIG. 1).

The non-slip tip 4 is made of non-metal, that is, a tip body 5 of a desired shape made of natural rubber, synthetic rubber, synthetic resin (vinyl chloride resin, polyurethane, etc.), or the like.
.. arranged in the chip body 5, and an example thereof is as follows. First, between the unvulcanized rubber sheets rolled into a sheet having a desired thickness, the string-like fiber material 6 is provided. A large number of ... are arranged in parallel to form the chip piece 4a, and the chip piece 4a is formed.
The desired number of sheets are superposed and hot air vulcanized (pot vulcanized) to have a desired thickness, and a gap 4b is formed between the chip pieces 4a, 4a. Chips 4 are formed.

Therefore, the anti-slip tip 4 has a surface 4 '.
From the bottom to the bottom are formed gaps 4b.
Further, the above-mentioned string-like fiber materials 6 are provided in a direction substantially perpendicular to the surface 5'of the chip body 5 (the string-like fiber materials 6 may be inclined so that the edge effect is not lost). At the same time, the upper end surfaces 6a ... Are exposed on the surface 5'of the chip body 5 (at least flush with the surface 5 ').

The shape of the cube-shaped or rectangular-shaped chip body 5 described above is merely an example. For example, a long-sized chip piece is formed into a spiral shape or a triangular column shape. The size and thickness of each of them are arbitrary, and the gap 4b is not limited to the depth from the surface 4'to the midway portion or the plane wave shape.

The string-like fiber material 6 includes a thin-diameter thread such as a thread made of cotton, nylon, polyester, rayon, steel or the like, or a large-diameter thread such as a rope, a rope or a rope.
A single yarn form, a twisted yarn form, etc. are optional.

In order to provide the anti-slip tips 4 on the anti-skid body 2, the un-vulcanized anti-slip body 2 is first prepared.
A desired guide groove is formed on substantially the entire surface of the surface 3, that is, the surfaces of the straight line portions 3a, the intersecting portions 3b, and the butting piece portions 3c.

Then, the anti-slip chips 4 are pushed into the respective grooves to be embedded therein, and after the embedding of all the anti-slip chips 4 is completed, the entire anti-slip device main body 2 is press-vulcanized, whereby the anti-skid device body is pressed. Vulcanization molding is carried out together with 2, and the non-slip chips 4 ... Are embedded integrally.

The surface 4'of each of the non-slip chips 4 ...
Is exposed so as to be flush with the surface 3 of the anti-skid body 2.

Therefore, when the tire slip stopper 1 is mounted on the tire 7 and travels, the slip stopper body 2 surrounded by the string-like fiber material 6 is compressed by the fiber material 6 when it comes into contact with the road surface. The dents and the string-like fiber materials 6 ... Independently move one by one in all directions, so that the unevenness of the snow and snow surface can be captured and the string-like fibers exposed on the surface 4'of the anti-slip tip 4 The edge effect (strap effect) of the material 6 produces resistance in all directions to exert a stable grip performance, and the string-like fiber material 6 exposed on the surface 4 ′ absorbs and removes water. At the same time, the water film on the snow and snow surface is sucked up and removed in the space created between the fibrous materials 6 ... And the clearance 4b, so that the friction effect and the adhesion to the road surface are enhanced.

The above-mentioned tire slip stopper 1 is merely an example. For example, the slip stopper body 2 has a shape as shown in FIGS. 4 and 5, or a so-called not shown shape, The shape such as a ladder type is not limited in any way, and it corresponds to all non-metal tire anti-skid devices, and the anti-slip tips 4 are not limited to the entire area of the surface 3, but intersect at desired positions, for example, as shown in FIG. Only the portions 3b ... Or, although not shown, only the straight line portions 3a .. may be provided, and the shape may be substantially the same as the shape of the mesh 8 as shown in FIG. FIG. 7 shows another embodiment of the non-slip chips 4 ... In which the chip pieces 4a are erected on the base plate 9 and the side surfaces of the respective chip pieces 4a are separated from each other to form the gap 4b. Other configurations and operational effects are almost the same as those of the non-slip tip 4 shown in FIG. 2, and the same reference numerals are given to the same portions and the description thereof will be omitted. Compared to the edge effect.

In the above embodiment, the anti-slip tips 4 are pushed into the guide groove provided in the surface 3 of the anti-skid body 2 in advance, and then the entire anti-slip tool body 2 is press-vulcanized. The present invention is not limited to this. For example, a guide groove may be provided at the time of vulcanization of the anti-skid tool body 2, and after the vulcanization, the anti-slip tips 4 may be inserted and fixed in the guide groove, or without providing the guide groove. It may be directly pushed in, or an adhesive may be added when pushing it in.In addition, a recess for chip insertion is provided on the surface of the anti-slip tool body after vulcanization, and a slip is secured in the recess with an adhesive. The chips 4 may be inserted and fixed by adhesion (not by vulcanization adhesion).
