Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an automobile tire anti-slip device that prevents automobile tires from slipping on snowy, frozen, muddy, or other road surfaces.

(Prior Art) Conventionally, metal chains have been widely used as anti-slip devices for automobile tires, but they are heavy and inconvenient to handle, and they also cause vibrations and vibrations of the car when driving on roads that are clear of snow. The disadvantages are that it is very noisy and difficult to drive, and that the road surface and chain are subject to significant wear and damage.

In order to improve this problem, anti-slip devices for automobile tires made of elastic materials (for example, Japanese Utility Model Publication No. 13126/1982) have become popular. Among these, the elastic mesh rubber band is particularly highly evaluated because of its anti-slip effect, excellent drivability, and durability, but the elastic mesh rubber band needs to be firmly connected at both ends to form a ring shape. Many methods have been used in the past.

(Problems to be solved by the invention) A device in which both ends of an elastic mesh rubber band are connected with metal fittings requires a lot of work when installing it on a tire.
Another disadvantage is that the metal fittings may be damaged due to wear while the car is running.

There is also a method of attaching a connecting piece to the top surface of one of the meshes of an elastic mesh rubber band and inserting this into the other vertex mesh to connect the band. Because these parts intersect and overlap at the tire tread, when the car brakes or starts, a strong load is placed on this part, causing significant wear and tear, which can lead to damage.

(Means for Solving the Problems) In order to improve the above-mentioned drawbacks, the present invention has been improved so that the mesh part of the tire tread part and the connecting part do not cross or overlap and can be easily and firmly connected. It is something.

The present invention consists of an elongated elastic mesh rubber band with a length sufficient to surround an automobile tire, string passing holes formed protruding from both ends of each mesh of the mesh rubber band, and an elastic In the anti-slip device for a tire configured to be connected in a ring shape by a tightening string inserted into the string passing holes at both ends of the mesh rubber band and a connecting fitting connecting both ends of the tightening string, the elastic mesh rubber band An abutting portion projecting laterally and a connecting portion having a metal fitting through hole are integrally molded at both longitudinal ends of the elastic mesh rubber band. The anti-slip tool for automobile tires is characterized in that the connecting metal fittings are inserted into the two metal fitting through-holes that abut against each other, and the elastic mesh rubber bands are connected in a ring shape by means of a string latching fitting.

(Example) An embodiment of the present invention will be described below with reference to the drawings. In Fig. 1, reference numeral 1 denotes a cross-shaped mesh rubber band, and this mesh rubber band 1 is made by braiding reinforcing fiber-cored rubber cords into a lath mesh shape, press-molding it in a mold, and attaching it to the tire in a ring shape. It consists of a long and narrow mesh-like rubber band 1 that can be wrapped around a string, string-passing hole support portions 2 that protrude outward from both ends of each mesh, and a string-passing hole portion 3 formed at the tip of this support portion 2. The string passing hole 4 formed in the through hole portion 3 is formed so that its axis coincides with the axis of the mesh rubber band 1. This mesh rubber band 1 has string passing holes 3 formed on both sides thereof.
and the string passing hole support part 2 that supports it are braided with a rubber cord containing a reinforcing fiber core in a mesh shape using a middle mold and a supporting die, and the core forming the string passing hole is wound. The cord passing hole part is braided with a single cored rubber cord together with the mesh part, and the cord is inserted into a middle mold between the upper and lower molds and press-molded. Since the string passing hole 3 formed in the section is made of press-molded rubber string containing the same reinforcing fiber core as the mesh rubber band 1, sufficient strength can be maintained.

In the present invention, a cross-shaped mesh rubber band 1
Insert the tightening strings 5 into the string passing holes 4 of the string passing holes 3 which are protrudingly formed at a predetermined interval by the supporting portions 2 on both side edges of the It is configured to be hooked by a hook hole 7 of a connecting fitting 6 connected to the terminal and a string hooking fitting 8 connected to the end of the other string.

In the present invention, a cross-shaped mesh rubber band 1
A connecting part 10 having an abutting part 9 is formed at the longitudinal end 1A of the body, and a fitting through hole part 12 having a fitting through hole 11 for the connecting fitting 6 at the tip of the abutting part 9.
are formed so that the axes of the holes 11 are in the longitudinal direction of the mesh rubber band 1, and the mesh rubber bands 1,
1, and insert the connecting fitting 6 into the fitting through hole 11 of the fitting through hole 12 formed at the end of each abutting portion 9, 9. A string hook 8 is connected to the end of the other string 5 in a hook hole 7 formed at the end of the connecting fitting 6.
It is constructed so that it can be hooked and latched.

In FIG. 3, 13 is a normal rubber ring hook, 14 is a rubber ring hooked onto this to tighten the mesh rubber band 1, and 15 is a tire, showing the state in which the mesh rubber band 1 is attached.

In the present invention, since the abutment parts 9 and 9 provided at the ends of the mesh rubber band 1 in the longitudinal direction are integrally molded with the mesh rubber band 1 by means of linear reinforcing pieces 16, the mesh rubber band The part of the connection part 1 that comes into contact with the tire tread is the metal fitting through hole 12 on both sides.
The connecting part 1 between the connecting fitting 6 and the abutting part 9 inserted into the
Since the connection with 0 is strongly pulled in the direction of both side edges of the tire, it does not open in the longitudinal direction, and a strong connection is possible.

As shown in FIGS. 1 and 2, the mesh rubber band 1 of the present invention is inserted into the string passing holes 4 of the string passing holes 3 provided by the supporting parts 2 on both sides of the mesh rubber band 1, respectively. A metal fitting of the connecting part 10 in which the tightening string 5 is inserted and connecting fittings 6, 6 are attached to each end, and the abutting parts 9, 9 formed at both longitudinal ends of the cored mesh rubber band 1 are abutted against each other. The connecting fitting is inserted into the through hole 11, and is hooked into the hooking hole 7 provided at the tip of the connecting fitting 6 with a string hooking fitting 8 connected to the end of another tightening string 5, as shown in FIG. In this way, the rubber ring 14 is hung around a plurality of rubber ring hooks 13 provided at equal intervals on the tightening string 5 on one side, and is irremovably attached to the tire 15.

(Effect of the invention) The effect of the invention is that the abutting portions 9 provided at the left and right connecting portions avoiding the tire tread portion abut against each other and connect both ends of the mesh rubber band, resulting in the following effects. There is.

In the present invention, the abutment part 9 is abutted and joined at the side edge that is off the tread surface of the tire, and unlike conventional products, the connecting piece and the mesh overlap at the tire tread surface. Therefore, when the vehicle is running, the overlapped connecting portions will not be subject to excessive loads and will not be worn out and damaged.

The butt part meets at the side edge of the tire, avoiding the tread, so even if it is subjected to strong stress, the butt position will not shift and no excessive load will be applied to the connecting fittings, making it safe and strong. Can be connected.

Between the abutment parts 9 on both sides, a linear reinforcing piece 16 perpendicular to the longitudinal direction is integrally molded with the mesh rubber band 1 and connected, so that the abutment part 9 can be connected even when mounted on a tire and driven. , 9 can be connected without opening to provide sufficient reinforcement.
