Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tire anti-slip device that prevents tires from slipping on snowy or frozen road surfaces.

(Prior Art) In recent years, tire slip prevention devices made of rubber or plastic have been used instead of metal chains, which are less noisy, cause less damage to roads, and have excellent durability. In particular, F.F.
With the proliferation of cars, mesh-type (net-type) anti-slip devices have become popular due to their excellent handling stability.

(Problem to be solved by the invention) Rubber and plastic tire slip prevention devices have various advantages over metal chains, but they have not yet become widespread among users. , sudden starts, high-speed driving, etc., can cause problems such as slippage of the anti-slip device and damage to the vehicle, or slipping of the anti-slip device, which can lead to accidents. Furthermore, since the anti-slip device has a flexible structure, it also has the disadvantage that it takes time to attach and remove it if you are not used to it.

That is, in the conventional tightening method, as shown in FIG. 1, a rope fixing fitting 14 is attached to a conventional mesh rubber band 1', and a fiber rope 6 is inserted into this for tightening. ing. However, since the mesh rubber band is a flexible structure and the fiber rope 6 is flexible when tightening, the distance between both ends of each mesh of the mesh rubber body cannot be fixed, and it takes time to attach and detach. The disadvantage is that there is a high risk of incorrect installation.

(Means for Solving the Problems) The present invention improves the drawbacks of the conventional tire skid device, improves the safety of the tire skid device, and makes it easier to handle.

Hereinafter, the term "rubber" in the present invention shall mean both rubber and plastics.

The present invention provides a mesh rubber band having a length approximately equal to the circumference of a target tire, and rope insertion holes formed protruding from both side edges of each mesh of the Y1 mesh rubber (IP). In a tire slip prevention device that includes a tightening rope inserted into the rope insertion holes on both side edges, and a connecting fitting connecting both ends of the tightening rope, each mesh of the mesh rubber band is inserted in the inner direction of the tire. A rope insertion vibrator is provided between each rope insertion hole on the side edge of the rope, and the rope is tightened by alternately inserting the rope through the rope insertion hole and the rope insertion pipe.

A rope insertion vibrator and an S-shaped fitting are provided alternately between each rope insertion hole on the side edge of each mesh of the mesh rubber band in the tire outward direction, and tightening is performed by inserting the rope into the rope insertion hole, the rope insertion pipe, and the S-shaped fitting. It is preferable to insert it into a metal fitting.

Note that spike metal fittings can be integrally molded at predetermined positions of each mesh of the mesh rubber band.

The rubber used may be either natural rubber or synthetic rubber, and rubber chemicals such as a vulcanizing agent may be added thereto. In particular, a compound containing a reinforcing agent such as carbon black and having excellent strength, abrasion resistance, cold resistance, and weather resistance can be used.

Any natural synthetic fiber can be used as the reinforcing fiber core material, but polyamide, polyester, aramid fibers, etc., which have excellent strength, are preferable.
Those treated with resorcinol, formalin, or latex are best.

The tightening rope used on the inner side edge of the tire when the mesh rubber band is installed is preferably a metal wire rope coated with synthetic resin; The attached rope is preferably a braid of natural or synthetic fibers.

The rope insertion pipe acts as a spacer to approximately fix the distance between the rope insertion holes, and has excellent strength, cold resistance, impact resistance,
Preferably, it is made of synthetic resin, which has excellent weather resistance. The connecting fittings and the S-shaped fittings are preferably made of mild steel with anti-rust plating.

Preferably, the tip portion of the spike fitting is made of tungsten carbide or titanium alloy, which has excellent wear resistance, and the shank portion and flange portion are made of carbon steel.

(Example) In the following, the invention will be explained in more detail with reference to the drawings.

In the embodiment shown in FIGS. 2 to 6, a mesh rubber band 1 having a length approximately equal to the circumference of the tire to be mounted is provided, and projections are formed on both side edges of each mesh of the mesh rubber band 1. A tightening rope 5.6 is inserted into the rope insertion hole 2 formed in the same manner, and a connecting fitting 7 for connecting both ends of the rope 5.6 is inserted into the rope insertion hole 2 on both side edges. 8 and has
A rope insertion vibrator 4 is provided between each rope insertion hole 2.2 on the inner side edge of the tire of each mesh of the mesh rubber band 1, and the rope 5 is tightened between the rope insertion hole 2 and the rope insertion vibrator. 4 and 4, and a rope insertion vibrator 4 and a figure-8 metal fitting 9 are alternately inserted between each rope insertion hole 2.2 on the side edge of each mesh of the mesh rubber band 1 in the tire outward direction. , tighten the rope 6 through the rope insertion hole 2, the rope insertion vibrator 4,
The rope is inserted through the combination of the rope insertion hole 2 and the figure 8 fitting 9 repeatedly. At the desired position of each mesh of the mesh rubber band 1,
The spike fittings 10 are integrally vulcanized and molded.

For tightening, connecting fittings 8 are attached to both ends of the rope 5. That is, in tightening the tire slip prevention device of the present invention, the length of the row 15 is configured to be shorter than the length in the longitudinal direction of the mesh rubber band 1, and is provided protruding from one end of each mesh of the mesh rubber band 1. Since the rope insertion pipe 4 is arranged between the formed rope insertion holes 2.degree.2, the distance between the rope insertion holes 2, 2 is substantially fixed.

A rope insertion pipe 4 and a three-shaped metal fitting 9 for attaching a rubber ring 12 are installed between the rope insertion holes 2, which are formed by protruding from the other end (outside the tire) of each mesh of the mesh rubber band 1. They are provided alternately and tightened by attaching connecting fittings 7 to both ends of the rope 6.

During installation, the rope 6 is tightened to fit the tire 13 after the tire slip prevention device is installed, and the end of the rope 6 is fixed with the rope end fixture 11. After that, attach the rubber ring 12 to the 3-shaped metal fitting 9, and attach the tire 1.
3) Attach the anti-slip device to the tire sufficiently.

(Effect of the invention) The tire slip prevention device of the present invention has a rope 6 for tightening the tire.
Since it is double-tightened with the rubber ring 12, there is no possibility of incorrect installation method, and there is no risk of the anti-slip tool being displaced and damaged due to steering wheel, sudden start, high-speed driving, etc. In addition, when the mesh rubber band 1 is vulcanized and molded, the spike metal fittings 10 are integrally embedded and molded in the desired positions of each mesh of the mesh rubber band 1, so that the spike metal fittings 10 are firmly prevented from slipping. It can be fixed to the tool body, there is no fear that the spike fitting 10 will collapse between the tire tread surface and the road surface, and the anti-slip effect will be great. Furthermore, the spike fittings will not fall off even during long and harsh driving.

Furthermore, the tire slip prevention device of the present invention can be easily attached and detached, and is easy to handle even for beginners. Therefore, the tire slip prevention device of the present invention has extremely great practical effects in terms of functionality and safety.
