[Industrial applications]

 The present invention relates to an improvement in a cable-type tire anti-skid device for automobiles used for traveling on ice and snow roads, and in particular, on the ice and snow roads with many exposed road surfaces, it improves the climbability of the vehicle and reliably prevents skidding. The purpose is to improve braking performance and durability.

[0002]

[Prior Art]

 As shown in FIG. 6, a conventionally known cable type tire anti-skid device comprises an outer side wire 1 along the outer tread surface of the tire and an inner side wire 2 along the inner tread surface of the tire. Between two parallel side cables, a cross cable 3 in which a spring 4, a collar 5, etc., which are wound in a coil at regular intervals, are inserted, and a folded back crushed portion is provided at each end of the cross cable 3. Each of them is attached in an orthogonal state through the side metal fittings 6 that are provided, and further, a plate hook 7 and a hook metal fitting 8 are provided at both ends of the tire corresponding to the inner circumference side of the tire, and a cut end portion corresponding to the outer circumference side of the tire. The S-shaped plate hook 9 is attached to one side of the through the end link 10, the stopper 11 and the end fitting 12, and the other side is attached to this. The C-shaped link 13 is constituted by oppositely arranged.

[Problems to be solved by the device]

 However, the above-mentioned conventional cable-type tire anti-skid device has sufficient strength because it has a high tensile property in the length direction of the cable and a certain degree of flexibility, and it has a local strength. Since it is possible to minimize such repeated bending stress and is excellent in workability, it has been widely used.On the other hand, when the tread portion of the cross cable is located directly under the tire when the vehicle is running, the tire is The surface of the tire is separated from the road surface as if a cross cable intervenes a rod-shaped roller between the road surface and the road surface.

Therefore, especially on an ice-snow road with a relatively small amount of ice and snow and a large amount of exposed road surface, slippage is likely to occur, which is rather dangerous because the climbability and braking performance of the vehicle are considerably deteriorated. In addition, there is also a problem that it is easy to slip because there is almost no frictional resistance in the axial direction of the wheel.

 In view of this, the present invention solves the various problems in the above-mentioned prior art, and the tread portion of the cross cable and a part of the tire are always in contact with the road surface while the vehicle is traveling, and the local portion for each cross cable is The purpose of this is to avoid the stress concentration, and to prevent the cross cable from being damaged by hitting the road surface while the vehicle is running.

That is, the present invention is a ladder-type tire anti-slip device configured by bridging a cross cable between two parallel side cables, and bridging between the two side cables described above. The present invention relates to a cable type tire anti-skid device characterized in that one diagonal line forms a polygonal tread surface in which the side cable extends in the lengthwise direction of the side cable.

Further, in the present invention, the polygonal tread formed by the cross cable bridged between the above-mentioned two side cables has one diagonal line oriented in the length direction of the side cable.
