DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. 1 to 4, in which a ladder-shaped metal chain is mounted on a tire. In FIG. 1, reference numeral 1 denotes a widely used automobile tire, in which a ladder-shaped chain holding groove 3 is engraved so as to go around the entire outer peripheral portion of the tire 1.
The chain holding groove 3 serves as a normal tire groove except during a snowfall in winter, and is provided so that a chain 2 described later is mounted at the time of snowfall.

The chain 2 to be mounted in the chain holding groove 3 is made of iron or other metal, and has a ladder-like shape similar to the chain holding groove 3, but has a lateral width (e.g. The width of the chain-like member 4 (described later) is formed slightly narrower than the chain holding groove 3. For example, if the chain holding groove 3 is set to have a groove width of about 1 cm, the chain 2 has a width of about 1 cm. It is provided so as to have a width of about 8 mm. Further, when the thickness of the chain 2 (thickness of the chain member 4) and the depth of the chain holding groove 3 are substantially the same, when the chain 2 is mounted in the chain holding groove 3, the chain member 4 It is configured such that only the provided protrusion 5 protrudes outward.

Each of the chain members 4 forming the chain 2 is formed in a thin and substantially box-like shape as shown in FIG. 2, and is connected by a connecting member interposed between the chain members 4. The chain 2 is configured to be capable of bending. Further, a substantially cross-shaped projection 5 is provided on the upper surface of the chain member 4 on the front side.
Each of the cross-shaped protrusions 5 exerts a strong impact on the frozen snow surface and exerts a high braking force, so that a large running performance on ice and snow can be obtained. It is. Furthermore, this cross-shaped projection 5
As shown in FIG. 3, the chain 2 itself does not come into contact with the road surface, and the protrusion 5 alone scratches the ice and snow surface to exhibit an anti-slip effect. The car can be run while running. In this embodiment, an example is shown in which the protrusion 5 is formed in a cross shape. However, the shape of the protrusion 5 may be other shapes such as a cylindrical shape or a three-letter shape. .

Next, a connection state of both ends of the chain 2 will be described with reference to FIG. The connection of the chain 2 in the present embodiment is performed by connecting a projecting engagement piece 6 extending from one end of the chain 2 and a concave engagement piece 7 extending from the other end.
The shafts 8 are inserted between the two connecting members, and are fixed using screws 9 from the outside of the shafts 8. The connection between both ends of the chain 2 is not limited to the connection method using such a shaft rod, and any other connection method may be adopted.

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, the chain 2A is formed in a ladder shape by a rubber plate material.
A large number of metal protrusions 5 are appropriately arranged on the upper surface of the front side. The projection 5 is formed in a substantially cylindrical shape and further has a small projection 10 protruding from the upper surface thereof. When the chain 2A is mounted on the tire 1, the projection 5 and the small projection 10 are formed. Only the protrusion 10 protrudes outward from the surface of the tire 1. As described above, the chain 2A of the present embodiment is made of a rubber plate, so that it is lightweight, and has a structure that it is easy to be mounted on a tire because it is flexible. The shape of the projection 5 is not limited to a cylindrical shape, and may be provided in a cross shape as in the previous embodiment, and the small projection 10 may not be provided. In addition, the connecting method of the ends of the chain 2A is performed by using a known connecting means, and the other structure is the same as that of the previous embodiment, so that the description thereof is omitted.

Next, still another embodiment will be described with reference to FIG. In this embodiment, the chain holding groove 3 and the chain 2 or 2A are provided not in a ladder shape but in a belt shape. One or two of the belt-shaped chains 2 or 2A are mounted in a chain holding groove 3 formed in the same shape. FIG. 6 shows a belt-shaped chain 2A formed of a rubber plate material. A state in which the end portions are connected in a ring shape according to the size of the tire 1 is shown. Also, a metal projection 5 is provided on the front side upper surface of the chain 2A at an appropriate interval as in the previous embodiment, and a small projection 10 is further protruded from the projection 5. Is also good. Although not shown, FIG.
Needless to say, the metal chain 2 as shown in FIG. 2 may be provided in a belt shape as shown in FIG.

Since the present invention is configured as described above, the chain is always stored in another place and is mounted on a tire at the time of snowfall or the like. If the chain is to be mounted on a tire, it can be mounted manually, but the chain must be unfolded on the road, and the car can be moved over the tire so that the tire passes over it. The chain can be mounted (buried) inside.

[0015]

The automobile tire of the present invention and the tire chain to be mounted on the tire are mounted and used as if the chain were buried in the chain holding groove of the tire.
As the anti-slip effect, the construction is such that only the projecting body provided on the chain exhibits the running performance on ice and snow, so it is possible to reduce the impact on the occupant while the car is running and to damage the road surface There is a great effect that the noise generated when the vehicle is running can be reduced, and the chain is not exposed to the outside, so that it has an advantage that it can give a smart feeling to the appearance. Furthermore, if the anti-slip protruding body is formed in a cross shape or a small protruding body is further protruded on the upper surface of the protruding body, extremely high performance on ice and snow can be exhibited and the car can be safely operated. There is a feature that it can be operated. When the chain is formed of a rubber plate, the weight of the entire chain can be reduced, and the chain has flexibility, so that the tire can be easily mounted on the tire and an inexpensive product can be manufactured. There is an advantage that it can be provided.
