ンに代わつて注目されている。(Prior art) When driving on snowy or icy roads, non-metallic tire skids made of substantially rubber, such as those formed with a ladder-shaped or tortoise-shell mesh-like part, or those formed in a chain shape, are used. However, recently it has been attracting attention as an alternative to metal chains.

方向に対して滑らないようにされている。 This type of anti-slip device includes a mesh type device having a rectangular mesh as shown in Japanese Patent Publication No. 18648/1983, and in this device, a net serving as a reinforcing material is covered with rubber. Spike pins are provided at the intersections of the meshes to prevent slippage in the axial and circumferential directions of the tire.

いる。 As a method for fixing the spike pins to the non-metallic tire anti-slip device, there are two methods: applying a strong adhesive in addition to the tips of the spike pins and embedding and fixing the spike pins into the anti-slip device body, and a special spike pin inside the main body. After implantation, methods are known in which both the upper and lower ends are caulked and fixed, and methods in which the material of the non-metallic tire skid stopper itself is made of a material with high rigidity, such as polyurethane.

いるためである。(Problems to be Solved by the Invention) The method using the adhesive has manufacturing difficulties, the upper and lower crimping method requires special pins and is expensive, and the material of the main body has to be made of a highly rigid material. If you use a slipper, the riding comfort will be poor, and the frictional force with the ice surface will be small, which will impair the functionality of the anti-skid device. Furthermore, in the above-mentioned conventional device, the spike pin fixed to the main body may fall off due to long-term use, impairing the functionality of the anti-slip device. This is because the main body is made of a soft elastic material such as rubber.

を採用した。(Means for Solving the Problems) The present invention was made in order to solve the above-mentioned conventional drawbacks, and is aimed at improving the function of the anti-slip device, improving productivity, streamlining, etc. As a means to achieve this purpose, in the spike pin attachment part provided on the rib of the main body of a non-metallic tire skid device made of substantially rubber, etc., which is used by being wrapped around a vehicle tire, A spike pin consisting of at least one flange provided on the body and a tip protruding in the axial direction of the body is embedded in the main body, and has a highly rigid cylindrical expansion/contraction that tightens the body of the spike pin from the outer periphery. In addition to adopting a configuration in which a tightening reinforcing body is embedded, a spike pin consisting of a body, at least one flange provided on the body, and a tip protruding in the axial direction of the body is used for vehicle use. When driving and fixing to the rib of the main body of a non-metallic tire skid device made of real rubber, etc. that is used around the tire,
A hole approximately the same shape as the trunk is provided in the main body, and a highly rigid cylindrical expansion/contraction tightening reinforcement body is embedded in advance concentrically with the hole, and the spike pin is driven into the hole to expand/contract. A method was adopted in which the spike pin is integrally fixed within the main body by expanding the tightening reinforcement body once and then contracting it so that the inner periphery of the expansion/contraction tightening reinforcement body bites into the outer periphery of the trunk of the spike pin and tightens it. .

方法。[Scope of Claims] 1. In the spike pin mounting portion provided on the rib of the main body of a non-metallic tire skid device made of substantially rubber, etc., which is used around a vehicle tire, A spike pin consisting of at least one flange and a tip protruding in the axial direction of the body is embedded in the main body, and a highly rigid cylindrical expansion/contraction tightening reinforcement body tightens the body of the spike pin from the outer periphery. A non-metallic tire anti-slip device equipped with a spike pin embedded therein. 2. A non-metallic tire made of substantially rubber, etc., in which a spike pin consisting of a trunk, at least one flange provided on the trunk, and a tip protruding in the axial direction of the trunk is used by being wrapped around a vehicle tire. When driving and fixing to the ribs of the main body of the non-slip device, a hole is provided in the main body with approximately the same shape as the body, and a highly rigid cylindrical expansion and contraction reinforcing body is embedded in advance concentrically with the hole. Then, after driving the spike pin into the hole and expanding the expansion/contraction tightening reinforcement body,
A spike pin of a non-metallic tire skid device, characterized in that the spike pin is integrally fixed within the main body by contracting and tightening the inner periphery of the expansion/contraction tightening reinforcing body to the outer periphery of the body of the spike pin. Fixing method.
