DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1A shows an auxiliary device for a tire anti-slip device according to the present invention. The auxiliary device A includes a grounding piece 1 and a locking claw 3 provided at each end of the grounding piece 1. Already tire C
Over the desired tire anti-slip device B wound around the vehicle, and the locking claw portion 3 is provided on the inner and outer sides of the tire anti-slip device B with the inner tightening rope B2 and the outer tightening rope B2. It is locked to a rope or a rubber band B3 or the like, and is individually and protrudingly mounted on the tire anti-slip device B.

The auxiliary tool A has a metal chain 2 provided inside a grounding piece 1 formed of, for example, rubber or synthetic resin into a rectangular shape (quadrangular cross section) as shown in the figure. Are formed by connecting a desired number radially through connecting fittings 4 and 4 or a single strip, and locking pawls 3 are provided on the free ends 1a of the grounding pieces 1 respectively. .

The assisting device A constructed as described above is, for example, a desired mesh shape (net shape) wound around the tire C.
Of the rubber tire anti-slip device B, the inner tightening rope B2 at the inner edge and the outer tightening rubber bands B3, B at the outer edge.
4 and B5, the respective locking claws 3 are locked, and each of the grounding strips 1 is hung over the tire anti-slip device B so as to be orthogonal to the longitudinal direction of the tread surface c so as to protrude. In this embodiment, four are mounted at opposing locations (the number of mountings is increased or decreased as appropriate according to the situation). When the auxiliary tool A is mounted as described above, first, the locking claws 3, 3 on one side are locked to the inner tightening rope B2 of the tire anti-slip tool B located inside the tire C, Each of the grounding strips 1 is wrapped around the anti-slip device B, and the other claw portions 3, 3
To the outer tightening rope or rubber bands B3, B4 and B5, the locking claws 3, 3 for locking to the inner tightening rope B2 are so arranged that the claw tip sides 3a, 3a face inward ( (Facing the tire C) to improve the ease of mounting (see FIG. 3).

Therefore, as shown in FIG. 3, the position where the auxiliary tool A is attached is equivalent to the height (thickness) of the grounding pieces 1 of the auxiliary tool A.
Since the groove, that is, the groove due to the difference between the surface of the ground contact strip 1 and the surface of the tire anti-skid device B or the surface of the tire C becomes deeper,
On a snowy road, a greater snow column shearing force (a force that steps on the snow and increases resistance) can be obtained.

The auxiliary tool A is not limited to the above embodiment, but may be any shape, such as a shape (a variety of plane shapes, cross-sectional shapes, etc., polygons, circles, etc.), material, etc. As shown in FIG. 4, one piece (a) formed in a long rectangular shape, the one formed in a substantially horizontal H shape (b), or the one formed in a substantially X-shaped surface shape (Not shown)
Changes within the scope of the present invention are free. Further, in the illustrated example, the overall shape formed by the above-mentioned grounding pieces 1 is formed in a size corresponding to the tread surface of the tire C (see FIG. 3), but the side surface (shoulder portion or 4 (a) (see FIG. 4 (a)), which may be large enough to hang on the side wall portion (in this case, the grounding piece which hangs on the side surface of the tire is preferably provided with a curved surface along the side surface in advance). The same applies to the case of b) and the like.

The tire slip stopper B to which the auxiliary tool A is attached is not limited to the rubber net-shaped one, but may be a conventional one such as a ladder type made of non-metallic material, a turtle-shaped type made of metal material, or a ladder type. It is possible to use a well-known anti-slip device. When an outer fastening rope is provided on the outer edge, the outer locking claws 3 are replaced with an outer fastening rubber band B3 or the like, and the outer locking claw portions 3 are replaced with the outer fastening rubber band B3 or the like. It is also possible to lock on a fastening rope.

Further, in this embodiment, the locking claw portions 3 of the auxiliary tool A are respectively locked to the inner tightening rope B2 and the outer tightening rubber bands B3, B4 and B5. However, this is only an example, and the locking position of the locking claw portion 3 is not limited to this. For example, any one of the outer tightening rubber bands B3, B4 or B5 is selected and locked. It may be fixed to the inner and outer sides of the tire anti-slip device B, and the hooks for holding the inner tightening rope B2 and the outer tightening rubber band B3 may be sandwiched or hooked. The movement to the left and right may be arbitrarily determined.

[0015]

According to the present invention, there is provided an auxiliary tool which is mounted on a tire anti-slip device wound around a tire. The auxiliary device includes a metal chain covered with a rubber or a synthetic resin. Formed and provided at the end of the grounding piece are locking claws for locking to an inner tightening rope and an outer tightening rope or a rubber band provided inside and outside the tire anti-slip device. Since the claw tip side of the locking claw portion that locks to the tightening rope is configured to face inward, each locking claw portion is mounted inside the tire anti-slip device already wound around the tire and mounted. When the grounding strip is hooked onto a desired portion of the tightening rope and the outer tightening rope or rubber band, and the grounding strip is protruded over the surface of the tire anti-slip device, the grounding strip of the auxiliary tool is consequently formed. Height (thickness) (Grooves due to the difference between the grounding piece surface and the tire slip instruments surface or tire surface) becomes deeper,
On snowy roads, a greater snow column shearing force (a force that squeezes snow and increases resistance) is obtained, and grip will be improved. In the event that inconvenience such as inability to run or the like occurs, the vehicle can be mounted urgently and easily, and it is possible to provide a vehicle which can sufficiently cope with an emergency.

In addition, it is considered that it is sufficient to simply mount another tire anti-slip device, but in this case, for example, when the vehicle cannot run on a place where jack-up is impossible (slope, deep snow), etc. Although it is not possible, since the present invention aid is partially attached to the surface of the tire antiskid device,
It can be easily and quickly mounted without moving the car, and is very easy to use and easy to achieve.
