The lip 10 near the bottom 11 has a ground line 11' on the bottom 11.
The grounding bulge 18 bulges further downward. That is, when the grounding bulge 18 touches the ground, the grounding resistance pushes up the grounding bulge 18 and elastically deforms the side pieces 12 A 12 B inward as shown by the dotted line in FIG. 8. By doing so, the width of the U-shaped portion of the wrapping portion 5 is reduced, so that the wrapping portion 5 is evenly and strongly clamped to the abdomen of the tire 8 from the left and right sides.

A block pattern in which the recesses 7 are grouped is formed on the grounding portion of the bottom 11 of the winding portion 6, and the block pattern is configured to provide an anti-slip effect.

The connecting piece 6 is paired with a female connecting piece 6M provided on one side and a bifurcated female connecting piece 6B provided on the other side.
A bottle insertion hole 14 for a connecting bottle is formed at the tip of the male and female connecting pieces 6M 6B, and when the male and female connecting pieces 5A5B are combined with each other and the connecting bottles are inserted into the bottle insertion hole 14, they are successively connected in series. The snow body and body 1 are connected to form a chain body.

Note that both ends of the bottle insertion hole 14 of the female connecting piece 6B are tapered to facilitate insertion of the connecting bottle at the edges of the bottle insertion hole 14 from which the ends of the inserted connecting bottle protrude from the female connecting piece 6B. A guide portion 16 is formed.

In addition, 8 in the figure is a spike bin provided above the ground contact part of the winding part 5, 9 is a locking bin for the tire 8 provided inside the winding part 6, and 20 is a linking part of the connecting piece 6 that is connected directly to the tire 8. This is a raised grounding point to prevent it from touching the ground.

On the other hand, the connecting portion 2 is a connecting portion of a two-fulcrum mechanism composed of a male connecting plate 17, a female connecting plate 18, and a book plate 19.

That is, the male connecting plate 17 is connected to the female connecting piece 6B of the snow body 1.
It has several bottle insertion holes 14 in parallel at one end so that it can be connected to a mouth plate 19, and the other end is bendably connected to a mouth plate 19. Further, one end of the female connecting plate 18 is connected to the snow kick body 1.
There are several bottle insertion holes 14 so that 6 female connecting pieces can be connected.
are arranged in parallel, and the other end is bendably connected to the plate 19. Then, when the female connecting plate 18 is pushed down and the opening plate 19 is brought down, the lock plate 19 and half of the male connecting plate 17 are stored in the recess 21 provided inside the female connecting plate 18, and the female and male connecting plates 11 ? 10 Jte ii!

The tire skid device of the present invention having the above configuration is deployed in a straight line in front of the drive wheel to be mounted with the winding portion 5 facing upward, and the snow kick body 1 is extended to the tire 8 by running gently on the winding portion 5 facing upward. When the two-fulcrum locking mechanism of the connecting portion 2 is closed, the tire is wound around the outer periphery of the tire 8 under tension as shown in FIG. 1.

The tire skid device of the present invention having the above structure can be attached to and removed from the tire even if there are fork bodies supporting the axle on both sides of the wheel, such as in a bicycle, so it is suitable for tires of motorcycles and bicycles as well. It is something to be applied.

According to the tire slip prevention device of the present invention described above, the snow kick bodies 1 made of synthetic resin having appropriate elasticity and rigidity are wound around the tire 8 in the form of a chain, so that the individual snow kick bodies 1 is sensitive to the deformation of the tire 8 upon contact with the ground, and the U-shaped part of the winding part 6 is narrowed by the ground contact bulge 18, and the side pieces 12 12B of the tire 8
Snoki strongly pinches from the left and right in proportion to the ground resistance of the snow.

The center of the snow kick body 1 and the tire 8 always match and fit onto the tire 8, which stabilizes the wrapping position. In addition, the noise level is extremely low, resulting in particularly excellent running performance.

Since the mounting means described above can be used for mounting on the tire, the mounting and dismounting operation can be done with one touch, making it extremely simple and easy for anyone, including women and inexperienced people ( (Approximately 2 minutes to attach) It has excellent attachability and can be attached and detached accurately.

Furthermore, the tire skid device of the present invention can adjust the unfolded length by adjusting the number of connections of the snow kick body 1, so it is versatile with respect to the circumference of the tire, and can be adjusted according to the cross-sectional shape of the tire. By simply preparing 8 to 4 types of snow kick bodies 1, it can be used for all types of vehicles and is economical.

- It is lightweight (approximately 4.5 kg or less for four-wheeled vehicles) and can be rolled up into a ball shape when removed from the tire, making it easy to handle and store.

- When the snow kick body 1 is provided with the pro, cup pattern and spikes of the above embodiment, it has a non-slip effect on both snowy road surfaces and ice slabs, and also has a sideways sliding effect on the tires, regardless of the location of use (early spring, etc.) It has all-purpose anti-tilt performance.

- Since the snow kick body 1 is made of synthetic resin, it can be colored freely, and the attachment of the tire anti-slip device can be confirmed from a distance by coloring, making it easy to manage the attachment.

There is no risk of "knocking noise" caused by improper installation on the tire.

・Due to its lightweight characteristics, the centrifugal force during driving is small, so there is little risk of it coming off while driving.

- When a conventional tire chain is run on an asphalt road surface, it breaks quickly, but the anti-slip device of the present invention is durable even when running on an asphalt road surface, and even if it breaks, it hardly damages the vehicle body.

Economical maintenance is possible by only partial replacement of the working snow ski and sliding body 1.
