た。2. Description of the Related Art Conventionally, in this type of spike fitting, there is one shown in FIG. 7 in which unevenness for preventing slip is formed on a ground surface of a fitting body. This spike fitting 100
In the mounting state, a concave groove 102 is formed on the grounding surface of the metal fitting body 101 which is bent in a substantially square annular shape and extends in the entire length of the metal fitting (in the width direction of the net). By forming the concave groove 102 along the center of the metal fitting body 101 as described above,
Two protruding portions 103 are formed on both front and rear edges of the ground contact surface so as to protrude relatively to the concave groove 102. In the spike fitting 100, the protrusion 103 serves as an edge portion that bites into a frozen road surface, thereby obtaining a grip performance.

Is difficult. Further, since the protrusion height of the protrusion 103 is determined relative to the depth of the groove 102 formed in the metal fitting body 101, the protrusion height of the protrusion 103 from the bottom of the groove cannot be made too high. Therefore, the traction and braking performance obtained by the protrusion 103 are also limited.

ことである。The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to improve the durability of the spike metal fitting by improving the abrasion resistance of the projection of the spike metal fitting as described above. The aim is to improve the traction and braking performance obtained by the protrusions, as well as to increase the traction.

In the spike fittings that fasten across,
A projection that extends in the width direction of the net on the ground surface of the metal fitting body is formed integrally with the metal fitting body.

As shown in FIG. 2, the spike metal fitting is attached to the stitch intersection b1 of the non-slip net b from the back side of the metal fitting main body 1 formed in a substantially U-shape. Is bent to the surface side of the non-slip net main body b, so that it is fixed in a form extending in the width direction of the net. Further, the above-mentioned non-slip net body b may be a conventionally well-known one, and its mesh shape is not limited to a rhombus shape as shown in the figure, but may be various mesh shapes such as a triangular shape and a rectangular shape. May be changed.

A belt-shaped steel material having a hardness of about HV is bent in a substantially U-shape, and a protruding portion 3 extending elongated along the entire length in the longitudinal direction of the metal fitting along a substantially center on the surface side of the metal fitting a is formed integrally with the metal fitting body 1. . The protruding portion 3 is a narrow band-shaped protruding portion extending in the net width direction on the grounding surface 4, and is formed by a cold rolling method or the like when manufacturing the metal fitting body 1. Although the above-mentioned protrusion 3 is formed so as to protrude from the ground contact surface 4 in a semicircular cross section, the protrusion shape of the protrusion 3 is not limited to this, and the cross section may be square, triangular or trapezoidal. It may be. Further, it is optional to form small irregularities on the surface of the projection 3.

突部3と段違い平行状となっている。The metal fitting body 1 has front and rear edge portions 1.
a and 1b are formed as a main body edge portion with a substantially right angle or a shape close to a right angle in cross section. The edges 1a and 1b are parallel to the protrusion 3 in a stepped manner.

Is provided, the cross-section becomes substantially convex, and the thickness of the metal fitting body 1 is increased by the amount of the protrusion 3 protruding from the flat plate constituting the metal fitting body 1, whereby the toughness of the metal fitting body 1 is increased and the wear resistance is increased. Performance can be improved. For example, when compared with a conventional metal fitting in which a metal groove is formed in the metal fitting body 1 to form a relative protrusion, the center of the grounding surface 4 is formed by the metal protrusion 1 instead of the metal groove. The reinforcing ribs are formed, and even if the front and rear edge portions 1a and 1b, which are liable to be worn by dry running, are worn, the strength of the metal fitting body 1 is obtained by the protrusion 3 projecting to the center of the grounding surface 4. And the grip performance can be maintained stably.

る。Further, the height of the projection 3 from the ground contact surface 4 to the maximum height of the projection can be freely set at the time of molding. Therefore, the traction and braking performance can be greatly improved as compared with the conventional one by making the protrusion height of the protrusion 3 sufficiently large. Although the height of the protrusion 3 is not particularly limited, it is not necessary to provide a very high height because the protrusion 3 is formed in a narrow band shape. Specifically, the protruding height from the ground plane 4 is about 0.5 to 1.5 mm.

As a result, when the spike fittings a and a 'located at each part of the net main body b start to contact the frozen road surface or the like, the protrusion 3
Is grounded together with the edge portions 1a and 1b of the metal fitting body 1 and bites into a wide shape, so that the hook on the frozen surface becomes strong,
Excellent braking effect was obtained. Therefore, by using the spike fitting a of the present invention, it is possible to provide a tire anti-slip net A having a good braking force on an ice burn (freezing road surface), thereby contributing to a reduction in rear-end collision, slip accident and the like.

上させることができる。[Effects of the Invention] As described above, the present invention is formed by projecting a projection extending in the width direction of the net on the grounding surface of the metal fitting body integrally with the metal fitting body. In addition to being able to be formed easily, the thickness of the metal fitting body can be increased by a projection that protrudes from the grounding surface of the metal fitting body while extending in the net width direction. By forming the groove, the metal fitting main body becomes tougher and the abrasion resistance can be improved as compared with the case where the protrusion is relatively formed by forming the groove. In addition, since it is possible to freely set the height of the protrusion from the contact surface to the highest portion of the protrusion, the protrusion height of the protrusion can be made sufficiently large to further improve traction and braking performance. .
