[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a cable type tire anti-slip device for automobiles used for traveling on ice and snow roads, and an object thereof is to improve the durability of the anti-slip device, the climbing property, and the running stability.

[0002]

[Prior Art]

 As shown in FIG. 2, a conventionally known cable-type tire anti-skid device includes an outer side cable 1a extending along the outer tread surface of the tire and an inner side cable 1b extending along the inner tread surface of the tire. The cross cable in which the spring 2, the collar 3, etc., which are wound in a coil shape at regular intervals, are inserted between the two parallel side cables according to They are attached in a state of being orthogonal to each other and are configured in a ladder shape as a whole, and further, at both ends of the side cable, coupling tools 6a and 6b for coupling with each other to form an annular shape are attached.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional cable-type tire anti-skid device, when this is installed and the vehicle travels on an ice / snow road, the side-slip of the vehicle is caused due to the extremely small slip resistance in the axial direction of the wheels. When driving on a snow-free road, there were problems that not only the vibration to the vehicle was severe but also the climbing performance was poor, and some skill was required for safe driving.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention solves the above-mentioned various problems in the prior art, secures the slip resistance in all directions of the road surface in this type of anti-skid device, and at the same time suppresses the climbing and traveling vibrations. It is designed to be drastically reduced and to have improved durability.Specifically, it should be parallel to each other with a certain interval, and the positions corresponding to the left and right ends of the tread surface of the tire to be mounted should be set respectively. Plural pairs of cross cables connected by locking hooks are arranged between two parallel side cables at intervals larger than the distance between the pair of cross cables described above and along the length direction of the side cables. While crossing over, pull one of the above pairs of cross cables together with one of the pair of adjacent cross cables at the center with pulling metal fittings. And by the above pair of side cables, it relates to a cable-type tire antiskid device consisting by spaced apart from each other in the central portion.

[0005]

[Action]

 As described above, by pulling one of each pair of cross cables spanning the lengthwise direction of the side cable and the other of the pair of adjacent cross cables and the pulling metal fitting at the center, If the side cables of each pair are configured to be separated from each other at their center portions, the center portions of the cross cables of each pair are separated from each other between the left and right side cables, and as a result, the side cables of each pair are separated. A roughly hexagonal shape is formed between the cables, and any part of the cross cable will always come into contact with the road surface between the tire and the road surface, and not only in the radial direction of the tire but also in the thrust direction. It can exhibit slip resistance in all directions.

Further, in the above-mentioned hexagonal cross cable, since any part of the locking hook and the pulling metal, and the cross cable is always in contact with the road surface between the tire and the road surface, Very little vibration is generated when driving. Moreover, since the pair of cross cables described above are connected in parallel at the positions corresponding to the left and right ends of the tread surface of the tire to be mounted with the locking hooks in parallel, a cross metal fitting for bridging the cross cable and the side cable. The joint with and is not bent excessively, and is always laid at right angles to the side cables. As a result, the joint is not damaged and the durability is significantly improved.

Further, in particular, the above-mentioned pair of cross cables are parallel to each other with a constant space as described above, and the positions corresponding to the left and right ends of the tread surface of the tire to be mounted are respectively locked by hooks. Because of the connection, in addition to the construction of the pulling fitting and the hexagonal cross cable when the vehicle travels, the locking hook acts to surely prevent the tire from sliding in the axial direction.

Further, a spring wound in a coil shape and a roller are inserted into each cross cable, and each cross cable is arranged in a direction inclined with respect to the rotation axis of the tire. As a result, the slip resistance in the axial direction of the wheel can be more reliably ensured.

【Example】

 The concrete contents of the present invention will be described below with reference to the embodiment of FIG. 1. 11a and 11b are two side cables parallel to each other, and 12a and 12b are between two side cables 11a and 11b. , A pair of cross cables, which are parallel to each other with a certain distance a, and which are connected by locking hooks 16a and 16b at positions corresponding to the left and right ends of the tread surface of the tire to be mounted, are connected to the side cable. By using the cross metal fitting 13 for crimping and fixing, the side cables 11a and 11b are paralleled to each other between the two side cables parallel to each other at a distance b larger than the distance a between the pair of cross cables. Multiple pairs are laid across the length of the cable.

Further, each pair of cross cables 12a and 12b laid in parallel are connected to each other and one pair of cross cables 12a and 12b adjacent thereto by pulling metal fittings 17 at their respective central portions. The pair of cross cables 12a and 12b are separated from each other at their central portions, so that a substantially hexagonal shape is formed between the pair of cross cables 12a and 12b.

Fasteners 18 and 19 are attached to both ends of the above-mentioned two side cables 11a and 11b, respectively. Further, the cross cables 12a and 12b include a collar 14 and a coil at regular intervals. A spring 15 wound in a shape is inserted. In the above embodiment, one cross cable 12a and 12b is attached to each end of each of the two side cables 11a and 11b, so that the tire is endlessly attached to the tire. In this case, one substantially hexagonal shape is formed between the side cables 11a and 11b, but the invention is not necessarily limited to these configurations, and the side cables 11a are not limited thereto. A pair of cross cables 12a and 12b may be attached over the entire length of 11b.

[Effect of the device]

 As described above, the present invention spans a plurality of pairs of cross cables parallel to each other between two side cables in the length direction of the side cable, and adjoins one of the pair of cross cables. One of the pair of cross cables and the center of the cross cables are pulled together by the pulling metal fittings so that the pair of side cables are separated from each other in the central portion to form a substantially hexagonal shape. The grip force of the vehicle has been significantly improved, and when the vehicle travels, not only the rotation direction of the wheels but also the slip resistance in the axial direction is improved, improving stability and running performance on ice and snowy roads, and climbing slopes on snowless roads. Also excellent in sex.

[0013] Furthermore, in particular, each pair of cross cables laid between the two side cables are laid over the cross cable and the side cable because they have pulling metal fittings for pulling the central parts toward each other as described above. Since there is no extreme bending at the joint with the cross metal fittings and it is always laid at right angles to the side cables, the joint is not damaged and the durability is significantly improved.

Not only that, a plurality of pairs of side cables are spanned in the length direction of the side cables at intervals larger than the distance between the pair of cross cables, between the two parallel side cables, and as described above. Since there are locking hooks that connect positions corresponding to the left and right ends of the tread surface of the tire to be mounted, the locking hooks, together with the pulling metal fittings, significantly increase the slip resistance in the axial direction of the wheel. It is possible to improve driving safety.

Further, between the tire and the road surface, any part of the hexagonal cross cable and the locking hook always comes into contact with the road surface, and as a result, vibration occurs when the vehicle runs. In addition, each cross cable has a coiled spring and roller inserted through each cross cable, but each cross cable is arranged in a direction inclined with respect to the tire rotation axis. As a result, the slip resistance in the axial direction of the wheel can be made more reliable.
