Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a non-slip body of a non-slip device for tires.

(Prior Art) B shown in FIG. 13 is a conventionally well-known anti-slip device for tires, in which an anti-slip body 31 of a predetermined width is stretched between both the inner and outer surfaces of the tire body through the tread surface.
Tightening ropes 32, 32' are hung between the inner and outer ends of these anti-slip bodies 31 via hook fittings 33, and the anti-slip bodies 31 are connected at predetermined intervals.

As shown in FIG. 14, the anti-slip body 31 is formed by forming a non-slip body 31a using rubber into a shape that follows the tread surface and both inner and outer surfaces of the tire body.
In addition, hook fittings 31b, 31b for hooking the hook fitting 33 are provided inside both the inner and outer ends, and
One or several wires 31c are passed through the anti-slip main body 31a and stretched between these latches 31b, and the tensile strength is maintained by the wires 31c.

When touching the ground, the anti-slip body 31
A strong force is applied to turn the central portion of 1a inside out. However, in the above-described anti-slip body 31, since the wire 31c is installed inside the anti-slip body 31a along the approximate center of the anti-slip body 31a, the elastic anti-slip body 31a is wound around the strong wire 31c. This causes vibrations and noises to be generated during driving, and there is also the problem that the anti-slip body can be torn and torn in a relatively short period of time.

(Technical Problem) The technical problem of the present invention is to increase the rigidity of the anti-slip body against turning over.

(Means for solving the technical problems) The means for solving the above-mentioned technical problems of the present invention is to arrange a predetermined number of anti-slip bodies of a predetermined width that are stretched between the inner and outer surfaces of the tire body through the tread surface. In the anti-slip body of the anti-slip device for tires, which is formed by connecting both the inner and outer ends of each anti-slip body at predetermined intervals with a tightening rope, the anti-slip body is formed of rubber or synthetic resin. , substantially ring-shaped latching metal fittings are internally provided at both the inner and outer ends of the anti-slip body, and extend over the entire length of the anti-slip body;
A plurality of belt-shaped core materials made of high tensile strength fibers and having approximately the same width as the main body of the anti-slip body are passed through both ends of each of the above-mentioned latching fittings, and then folded back in the same direction and latched therein. It is characterized by

(Function) According to the above means, the anti-slip body and the plurality of belt-shaped core materials, whose ends are folded back in the same direction and arranged in a superimposed manner, are completely bonded over the entire width and are integrated. .

When the latches at both ends of the anti-slip body are pulled toward the center of the tire by both the inner and outer tightening ropes, tension is applied to the multiple core strips of polymeric material between the latches, causing the tire body to tighten. The anti-slip body body, which is in close contact along the tread surface and both inner and outer surfaces and is integrally fleshed out around each core material, is brought into close contact with the tire surface.

When the non-slip body touches the ground while running and a force is applied to the tread surface of the non-slip body, both ends of the core material are folded back in the same direction, and both sides of the core material (both lengths) are folded back in the same direction. The sides (sides) resist the force that tries to roll up the anti-slip body by collecting forces in the same direction, thereby suppressing the deformation of the body.

(Effects) As described above, the present invention consists of a plurality of belt-shaped core materials made of high-tensile fibers and having approximately the same width as the non-slip body over the entire length of the non-slip body, and each end of which is attached to both latching metal fittings. The belt-shaped core material and the anti-slip body are firmly bonded over a wide area to integrate them, so the anti-slip body is Reinforced by the plurality of belt-shaped core materials folded in the same direction and formed in a polymeric manner, it is possible to significantly reduce the amount of curling deformation when touching the ground, and to increase the strength of the anti-slip body against cutting. .

Therefore, it is possible to reduce the vibration and noise generated due to the rolling deformation of the anti-slip body while driving, and also to prevent the anti-slip body from being twisted and torn.
