[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 snowy road surfaces, and in particular, it has markedly improved wearability to tires, durability of the anti-skid device, climbability, and traveling. The purpose is to improve stability.

[0002]

[Prior art]

 As shown in FIG. 3, a conventionally known cable-type tire anti-skid device includes an outer side cable 1a along an outer tread surface of a tire and an inner side cable 1b along an inner tread surface of the tire. According to the above, a cross cable in which a spring 2, a collar 3, etc., which are wound in a coil at regular intervals, are inserted between two parallel side cables, and side cables 5 are provided at both ends of the cross cable. They are attached in an orthogonal state and are configured as a whole as a ladder, 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, the anti-slip device is extended from the side of the ground contact point of the wheel toward the traveling direction of the vehicle, and then the vehicle is mounted. The wheels are moved and placed on the anti-skid device, and the both ends of the anti-skid device in the longitudinal direction are raised so as to surround the wheel. This is because the hooks are hooked to connect them to each other in an annular shape, and finally the intermittent part of the front side band, which is formed in an annular shape, is pulled in the axial direction by a tension metal fitting or the like to complete the attachment. In addition, the vehicle structure itself requires a great deal of labor and risk when installing anti-skid on a recent vehicle in which the space between the wheel and the vehicle body is narrow.

Not only that, it is not easy to adapt the cross cables individually to the uneven tread of the tire after being wound around the tire, and in the above-described non-slip device of the conventional structure, When traveling on a road, the sideways slippage of the vehicle is likely to occur due to the extremely small slip resistance in the axial direction of the wheels.In addition, not only the vehicle vibrates violently when running on a snow-free road, but also the climbing performance is improved. It was inferior and had some difficulties such as requiring a certain level of skill in safe driving.

[0005]

[Means for Solving the Problems]

 Therefore, in the present invention, the various problems in the above-mentioned conventional technology are solved, the wearability to the tire is improved significantly, and the slip resistance of this kind of anti-skid device in all directions of the road surface is secured. It is designed to drastically reduce climbing and driving vibrations and improve durability.Specifically, multiple cross treads are placed between parallel inner and outer side bands. In a tire anti-skid device in which hooks are attached to the ends of each of the above sidebands so as to engage with each other to form an annular shape, both ends of the outer sidebands are interposed, and chain links are interposed in the middle. And connect them to each other. It relates to cable-type tire antiskid apparatus characterized by comprising linked to each other via a metal fitting having a locking hook without mounting the coater sideband.

[0006]

[Action]

 With both ends of the inner side band as the entrance, put the anti-skid device from above the tire downward and rotate the wheel about 45 to 90 degrees to make the connecting part of the anti-slip device easy to work. The outer ends of the cross tread, which are located at both ends of the outer side band without being attached to the outer side band, are connected to each other via metal fittings with locking hooks. Ride on the front side of the tire and slide the outer sideband with a chain link in the middle toward the backside of the tire until the outersideband is fully extended, drop the cross treads at the both ends on the backside of the tire, and then place the inner sideband on the backside of the tire. Join both ends of each other.

Next, the outer side band having a chain link in the middle on the front side of the tire is pulled outward and the above-described upper cross tread is pulled out so as to be positioned at the center of the tire tread surface (at this time, the inner side band is It is stretched on the back side and adheres to the tire). Connect both outer side ends of the pulled out cross tread to the chain link of the outer side band described above, and finally, on the outer side (front side) of the tire, use a tensioning means such as a chain band to set the annular side band in the radial direction. Tension on and put on.

【Example】

 1 to 2 are inner side bands, 4 are outer side bands, and 8 is a cross tread. The inner side band 1 has a hook 2 at one end thereof and an annular connecting fitting 3 at the other end thereof so that they can be joined endlessly with one touch, and the outer side band 4 is A chain link 7 is interposed between the connecting rings 5.6 at both ends. The inner side band 1 and the outer side band 4 are parallel to each other, and a pair of two cross treads 8 are provided between the inner side band 1 and the outer side band 4 by crimping both ends with cross metal fittings 9 and 10, respectively. There is.

Further, the pair of cross treads 8 installed in parallel are held parallel to each other by the parallel metal fittings 11 and 12 at the positions near the side bands 1.4, and one of them and another adjacent thereto. Of the pair of cross treads 8 and the respective central portions thereof are attracted to each other by the pulling metal fittings 13 to separate the pair of cross treads 8.8 from each other in the central portions thereof. A substantially hexagonal shape is formed between each pair of cross treads 8.8. In addition, a collar and a spring wound in a coil shape at regular intervals are inserted into each cross-tread 8.

In the structure of the above-mentioned embodiment, the both sides of the inner side band 1 are used as entrances, and the slip prevention device is covered from the upper side to the lower side of the tire (T). Rotate about a degree to stop the joint part of the anti-slip device at a position where it is easy to work, and connect it to each other via the locking hooks C, which are located on both ends of the outer side band 4 without being attached to the outer side band 4. The outer side ends of the resulting cross tread 8 ride on the tread surface of the tire (T), and the outer side band 4 with the chain link 7 interposed in the middle is slid toward the rear side of the tire until the both ends described above. Drop the cross tread 8 on the back side of the tire, and hooks 2 and connecting metal fittings at both ends of the inner side band 1 on the back side of the tire. The inner side band 1 is formed into an annular shape by connecting the inner side band 1 and the inner side band 3 to each other.

Next, the outer side band 4 having the chain link 7 in the middle on the front side of the tire is pulled outward to pull out the above-described upper cross tread 8 so as to be positioned at the center of the tire (T) tread surface ( At this time, the inner side band 1 fully extends and is stretched and adheres to the back side of the tire). Further, the locking hooks C formed at both outer side ends of the cross-tred 8 that have been pulled out are joined to the chain links 7 of the outer side band 4, and finally at the outer side (front side) of the tire (T), the chain band is attached. The annular outer side band 4 is tensioned in the radial axis direction by a tensioning means such as the above to complete the mounting work.

When removing the side band 1.4, the vehicle is stopped when both ends of the side band 1.4 are located in the upper part, the tension means such as the chain band is released, and the hook 2 of the inner side band 1 and the connecting fitting are connected. After releasing the connection with 3, the whole anti-skid device is lowered toward the bottom of the tire (T) and then the vehicle is moved to remove the anti-skid device.

[Effect of device]

 As described above, the present invention has a plurality of cross treads mounted between the inner side band and the outer side band that are parallel to each other, and the ends of each side band are mutually attached to form an annular shape. In the tire anti-skid device with hooks for attaching the outer side band, both ends of the outer side band are connected to each other with a chain link in between, and the outer side of the cross tread located at both ends of the outer side band. Since both ends are connected to each other via the metal fittings that have the locking hooks without being attached to the outer side band, the cross tread fits well to the tire tread surface when mounted on the tire, and the tire The wearability with respect to is greatly improved.

Not only that, one of the two pairs of cross treads is pulled toward the other of the pair of adjacent cross cables by the pulling metal fittings in the central portion thereof to pull the side cables of the above pairs. However, when they are separated from each other in the central portion to form a substantially hexagonal shape, the grip force on the road surface is significantly improved, and when driving the vehicle, not only the rotational direction of the wheels but also the axial direction. It provides better skiing resistance, improves stability and running performance on icy and snowy roads, and excels in climbing on snow-free roads, resulting in good safety.

In addition, in particular, since each pair of cross treads bridged between the two side bands has the pulling metal fittings for pulling the central portions to each other as described above, the cross treads are bridged to the cross cable and the side cable. No excessive bending point is formed at the connecting part with the cross metal fitting, and it is always laid at right angles to the side cables, so that the connecting part is not damaged and the durability is remarkably improved.
