DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG.
The anti-slip net A includes a tire anti-slip net main body 1, a main spike metal 2, a sub spike metal 3, and the like.

The tire anti-slip net body 1 has a conventionally well-known shape formed of a non-metallic material such as rubber into a desired mesh shape (net shape) as shown in the figure. The material 1c (for example, wire, glass fiber, synthetic fiber, etc.) is shown inside, but the material without the core material 1c may be used arbitrarily. This is merely an example, and the present invention is not limited to the above-described net shape, but can be changed to a net shape of a conventionally known nonmetal tire anti-slip net body.

The main spike fittings 2 are formed of a desired steel material or the like in a belt shape and are well known in the art. The main spike fittings 2 are wound around the outer periphery of the desired intersections 1b. Has been established.

The sub-spike metal fitting 3 is made of a desired material such as a desired steel material or a material quenched into a desired steel material, or a highly wear-resistant material such as a cemented carbide material or a ceramic. A spike pin formed in a side surface inverted concave shape with the plate portion 3a, at a desired position (intersection 1b...) On the grounding surface side 1a of the anti-slip net main body 1 excluding the caulking portion of the main spike fitting 2. the main from the leg portion 3b side
It is embedded separately from the spike fitting 2, and the top surface 3a 'of the top plate portion 3a faces the ground surface side 1a of the non-slip net main body 1 substantially flush (see FIG. 2).

In this embodiment, the main spike fittings 2...
And the auxiliary spike fittings 3 ... at the intersection 1b of the net body 1 ...
Are arranged alternately, but the ratio is arbitrary, and the location of the main spike fittings 2 and the auxiliary spike fittings 3 is not limited to the intersections 1b and is optional.

The sub-spike metal fitting 3 has a height (thickness, length) at least corresponding to the wear amount (height) within the durability limit of the net main body 1, and the tread portion facing surface 1d of the net main body 1. As long as it is not exposed to the side, the height is arbitrary (thus not shown, but may be the full height within the thickness of the main body 1), and the shape is also a side surface shape T (not shown) or FIG. (A) A side surface inverted L-shape or the like in which a leg portion 3b is suspended from only one side edge of the top plate portion 3a shown in FIG.
Alternatively, as shown in FIGS. 3B and 3C, a projection 3c made of a cemented carbide or a highly wear-resistant material is provided on the pin body (in this case, the top surface 3c 'of the projection 3c is on the ground plane side). 1a
3 (d) is an arbitrary shape such as a cross-sectional view taken along line xx of FIG. 3 (c), and is not limited at all. Needless to say, the top surface 3 of the top plate portion 3a facing the ground surface side 1a.
The surface shape of a 'is arbitrary such as planar (circular, rectangular, etc.), linear, or dotted.

The sub-spike fitting 3 has a top surface 3a '.
It is sufficient that the top surface 3a 'is embedded in the ground surface 1a so as to be flush with the ground surface 1a as described above. (See FIG. 3E) or may be buried so as to be immersed (not shown).

The method of assembling the sub-spike metal fittings 3 will be described. The so-called non-slip net body 1 which is formed by braiding a filament material made of unvulcanized rubber and having a core material 1c therein, to form a braided body. At the time of preforming, the unvulcanized anti-slip net body 1 is buried by pressing into the desired intersections 1b from the leg portions 3b, 3b side, and then vulcanized and molded together with the anti-slip net main body 1. Body 1
It is formed integrally with. Therefore, the secondary spike
The top surface 3a of the shell 3 'is also the rubber material of the net body 1 slip on top covers the thin film, but the film-like rubber top surface 3a of quickly worn when traveling secondary spike bracket 3' There is no problem because it is exposed. Also the main spike fitting 2 ...
Is the desired intersection 1 of the vulcanized net body 1
b) and fix by caulking.

Furthermore, although optional, the auxiliary spike fitting 3
Can be removed by twisting the legs 3b, 3b by 90 ° with respect to the traveling direction, providing communication holes or grooves on the side surfaces of the legs 3b, 3b, or bending the legs 3b, 3b. It is good also as what aims at stopping.

Therefore, the tire anti-slip net A of the present invention
When the main spike fitting 2 caulked and fixed to the intersection 1b of the net main body 1 wears, the net main body 1
The top surface 3a 'of the top plate portion 3a of the sub-spike metal fitting 3 embedded in the base is exposed and grounded, and the main spike metal fitting 2
Relieves the ability to spike on frozen roads, which has been impaired by the wear of tires .

[0018] The main spike fitting 2 except crimping portion to the outer peripheral surface of the cross section 1b which the secondary spike fittings 3 are embedded, and further caulked main spike fitting 2 similar to the main spike fitting 2, This main spike fitting 2 has a secondary spa
The spike fitting 3 may be optionally included, and the swing of the main spike fitting 2 is reduced, thereby preventing early cracking from metal fatigue.

[0019]

Since the present invention, according to the invention] is structured as described above, caulking fixed to the net by winding into a desired cross-section of the net body
Even if the main spike fitting protruding from the main body surface is worn, the top surface of the sub-spike fitting buried separately from the main spike fitting on the net main body surface is gradually exposed and grounded. However, the spike function, which has been impaired by the wear of the main spike fitting, can be relieved by the sub-spike fitting continuing to exert its life. The life of the net body (the net body is damaged or the core material is exposed on the ground surface side) The spike function can be maintained for a long period of time as long as the anti-slip net body can be used without loss of the spike function at an early stage. Useful.

Further , it is embedded in the main body of the anti-slip net.
The secondary spike bracket has no exposed surface on the side facing the tread.
Not for spikes as a whole non-slip net
While increasing the number of fittings, spike fittings
