【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In the figure, A represents a tire anti-skid net of the present invention, and the anti-slip net A is a net body 1, spike fittings 2, ..., spike pins 3 ... It is composed of.

The net body 1 has a conventionally well-known shape formed of a non-metallic material such as rubber in a desired mesh shape (net shape) as shown in the drawing. In the illustrated example, the core material 1 c ( (For example, wire, glass fiber, synthetic fiber, etc.) is shown, but the core material 1c may be omitted and the net body 1 is also shown as an example. However, the shape of the net is not limited to the above, and it is possible to change to a net shape of a non-metallic net body that is well known at present.

The spike metal fitting 2 is a conventionally well-known one which is formed in a strip shape from a desired steel material or the like, and is wound around the outer periphery of the desired crossing portion 1b ... Has been done.

The spike pin 3 is a desired steel material or a product obtained by quenching a desired steel material, for example, a bottom plate portion 3a, and rising portions 3b, 3b formed by rising from both side edges of the bottom plate portion 3a. It is formed in a concave shape, and in the present embodiment, the tips of the rising portions 3b, 3b are made of high wear resistance material 3b ', 3b' such as cemented carbide material or ceramics (brazing or crimping). The net body 1 is embedded in the desired portion (intersection 1b ...) of the grounding surface side 1a excluding the caulking portion of the spike metal fitting 2 from the bottom plate 3a side, and the tops of the rising portions 3b, 3b are formed. The surface, that is, the top surface 3b ", 3b" of the cemented carbide material or the high wear resistant material 3b ', 3b' faces the ground surface side 1a of the net body 1 in a substantially flush manner (Fig. 2). reference).

If the rising portions 3b, 3b are formed by using a cemented carbide material or a high wear resistance material from the top surface to a desired position below (the rising end base ends 4, 4). Often, the range may be one formed by cemented carbide steel or high wear resistance material 3b ', 3b' only at the tip as described above, but it is not limited to this and is arbitrary and rises. The entire parts 3b, 3b may be formed of a cemented carbide material or a material having high wear resistance.

In the present embodiment, the spike metal fittings 2 ... And the spike pins 3 ... Are alternately arranged on the surface of the net body 1, but the ratio is arbitrary, and the arrangement parts are intersections. It is not limited to 1b ... but is arbitrary.

The method of assembling the spike pins 3 ... will be described. At the time of so-called preforming of the net body 1 in which a filament material made of unvulcanized rubber having a core material 1c inside is braided to form a braided body. Is formed by being pushed into the desired crossing portion 1b of the unvulcanized net body 1 from the side of the bottom plate 3a and then vulcanized together with the net body 1 to be integrally formed with the net body 1. is there. Therefore, the rubber material of the net body 1 may cover the top surface 3b ″ of the rising portion 3b of the spike pin 3 in a thin film shape, but the thin film rubber is worn away as soon as it runs and the spike pin 3 is worn. Since the top surface 3b ″ of is exposed, there is no problem. The spike fittings 2 are wound around the desired intersecting portions 1b of the vulcanized net body 1 and fixed by caulking. The relationship with the core material 1c is that both core materials 1c and 1c 'are passed between the rising portions 3b and 3b as shown in the figure, or only one core material 1c is passed as shown in FIG. (The same applies to the embodiment shown in FIG. 4).

The spike pin 3 may have any height (thickness, length) as long as it has a height (thickness, length) at least equivalent to the wear amount (height) within the endurance limit of the net body 1. The height of the main body 1 may be set within the thickness of the main body 1), and the shape thereof is the inverted T-shape of the side surface or the rising portion 3b is formed from only one side edge of the bottom plate portion 3a shown in FIG. It may be any shape such as the side surface shape L-shaped and is not limited at all. Needless to say, the surface shape of the top surface 3b ″ of the rising portion 3b facing the ground contact surface side 1a may be any surface shape (circular shape, rectangular shape, etc.), linear shape, or dot shape.

The top surface 3b ″ of the spike pin 3 has only to face the ground surface side 1a of the net body 1, and as described above, the top surface 3b ″ is flush with the ground surface side 1a. However, it may be embedded so as to be projected (see FIG. 5) or recessed (not shown) from the grounding surface side 1a.

Further, although optional, the spike pin 3 may be twisted by 90 ° with respect to the rising portions 3b, 3b with respect to the traveling direction, or may have a communicating hole or a surface on the bottom plate portion 3a or a side surface of the rising portions 3b, 3b. A groove or the like may be provided, or the bottom plate portion 3a and the rising portions 3b, 3b may be bent to prevent the stopper from coming off.

Therefore, when the tire anti-slip net A of the present invention is mounted on the vehicle and the spike metal fitting 2 fixed by crimping to the intersection 1b of the net body 1 is worn, the spike pin 3 embedded in the net body 1 ... Of the rising portions 3b ..., ie, the top surface 3b ″ of the cemented carbide material or the high wear resistance material 3b ′ is exposed, and the spike function to the frozen road surface is relieved and the cemented carbide material 3b ′ is The top surface 3b ″ of the net increases durability, and the wide bottom plate portion 3a embedded in the net body 1 prevents the net body 1 from slipping out.

Further, a spike metal fitting 2 similar to the spike metal fitting 2 is further caulked and fixed to the outer peripheral surface of the intersecting portion 1b in which the spike pin 3 is embedded except for the caulking portion of the spike metal fitting 2. The spike pin 3 may be included inside, which is optional, so that the swing of the spike metal fitting 2 is reduced and premature cracking due to metal fatigue can be prevented.

[Effect of the device]

 According to the present invention, a band-shaped spike metal fitting is wound around a desired intersecting portion of a non-metallic tire anti-slip net body and caulked and fixed, and a spike pin including a bottom plate portion and a rising portion raised from the bottom plate portion. Is embedded from the bottom plate side in a desired position on the surface other than the caulked part of the spike metal fitting, and the top surface of the rising portion of the spike pin is exposed to the grounding surface side of the net body. Since the structure from the top surface down to the desired location is made of cemented carbide material or high wear resistance material, the spike metal fitting wound around the desired intersection of the net body and fixed by caulking is worn. However, the top surface of the rising part of the spike pin embedded in the net body surface is exposed (the spike pin projection amount increases as the wear amount of the net body increases). Since the spike function can be relieved, the spike function will be lost early in relation to the life of the net body (such as when the net body is damaged or the core material is exposed on the grounding surface side). Nonetheless, as long as the non-slip net itself can be used, the spike function can be exerted for a long period of time, which is extremely useful and useful.

Further, since the spike pin has a top surface exposed on the surface of the net body made of a cemented carbide material or a high wear resistance material, it has excellent durability and can be used for a longer period of time. And a rising portion that rises upward from the bottom plate portion. Since the bottom plate portion is held in the net body, it is possible to effectively prevent the retainer from coming off.
