[Industrial applications]

 The present invention relates to a tire chain that is attached to a tire of a vehicle during snowfall or road surface freezing.

[0002]

[Prior art]

 Conventionally, a cross chain consisting of a number of chain links between a pair of side chains mounted on the inside and outside of a tire is a metal chain in which a chain chain or ladder shape is installed at appropriate intervals, and the inside of the tire. Also, there has been proposed a non-slip stopper made of rubber, plastic, or the like in which a slip prevention member is installed between a pair of binding members mounted on the outside in a ladder shape at appropriate intervals.

[0003]

[Problems to be solved by the device]

 However, the metal chain, on the other hand, has the drawbacks that it tends to skid, making it difficult for the vehicle to drive safely, and that the running noise is a little noisy. On the other hand, the other non-metal anti-slip device cannot be bent from the binding member or the anti-slip member when not in use, and the whole is bulky, which is inconvenient for packing, transporting, and storing. There were drawbacks such as being more expensive than the chain.

Therefore, the present invention has been devised to solve the above-mentioned problems, and when used, not only does the metal chain allow safe traveling of the automobile, but also when traveling, The running noise is quieter than that of a metal chain, the road surface is not damaged by a metal chain, and the braking effect is better than that of a non-metallic non-slip device. Like the chain, it is compact enough to be conveniently packed, transported and stored, and has a simpler structure than non-metallic anti-skid devices and is cheaper than non-metallic anti-skid devices. To provide various tire chains.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a metal cross chain consisting of a large number of chain links between a pair of metal side chains mounted inside and outside a tire, in a hexagonal shape or In a tire chain erected in a ladder shape at appropriate intervals, the thickness of a non-metallic non-slip member such as rubber or plastic abutting the tire tread surface on all or every one or more chain links of the cross chain. They are provided respectively.

[0006]

[Action]

 With the above-mentioned technical means, the skid of each of the cross chains can be prevented from being skided when it is mounted on the tire of an automobile during snowfall or when the road surface freezes. Each non-metallic cleat of the cross chain should be able to mute the sound, and when the brakes are applied while driving, the cleat of the chain link of the cross chain should sink and the chain link should hit the road surface. They should be in contact with each other, and when not in use, each chain link of the cross chain should be easily bent like a metal chain.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 7, the tire chain of the present invention includes a pair of metal side chains 1 mounted on the inside and the outside of the tire A and having a plurality of chain links 2 between them. In a tire chain in which cross chains 3 made of turtle shells or ladders are laid at appropriate intervals, all of the cross chains 3 or every other chain link 2 or a plurality of chain links 2 made of non-metal such as rubber or plastic. The anti-skid devices 4 are each provided in a thickness that makes contact with the tire tread surface B.

That is, as shown in FIG. 1 and FIG. 2, the cross chain 3 includes a plurality of horizontal links 5 to which a plurality of chain links 2 are connected. A vertical chain 6 to which individual chain links 2 are connected is laid via a connecting ring 7, and the cross chains 3 are alternately arranged between a pair of side chains 1. As shown in the figure, it is erected in a tortoiseshell shape at appropriate intervals. Further, in the cross chain 3, only a few horizontal chains 5 to which a large number of chain links 2 are connected may be installed between a pair of side chains 1 in a ladder shape at appropriate intervals. In this case, the chain link 2 has a straight elliptical shape as shown in FIGS. 1 to 4, but has a twisted substantially elliptical shape as shown in FIGS. 5 and 6. But either is fine.

Then, as shown in FIGS. 1 to 7, every other one of the metal cross chains 3 formed as described above or all chain links 2 are made of a non-metal non-slip material such as rubber or plastic. The tool 4 is provided with a thickness such that it is brought into contact with the tire tread surface B by a baking means, an adhesive means, a fitting means, a mechanical baking means, or the like. It is preferable that the shape of the anti-skid 4 has a V-shaped cross section so that the left and right link side pieces 8 of the chain link 2 can be locked. According to this, it is possible to prevent the slip stopper 4 from falling off while the vehicle is running.

In addition, in the straight chain link 2 having a substantially elliptical shape, the anti-skid 4 is shown in FIGS. 1 to 4 so as to be provided on every other chain link 2 of the cross chain 3, respectively. In the twisted substantially elliptical chain links 2, it is shown in FIGS. 5 and 6 that each chain link 2 of the cross chain 3 is provided, but any of these may be used. Without limitation, in the case of a straight chain link 2 having a substantially elliptical shape, it may be provided on all or a plurality of chain links 2 of the cross chain 3, or a twisted substantially ellipse. The shaped chain links 2 may be provided on every other chain link 2 of the cross chains 3 or on every other chain link 2. Further, although the anti-skid 4 is illustrated as being provided integrally with the chain link 2 of the cross chain 3, the present invention is not limited to this, and as shown in FIG. In addition, the upper anti-skid 4a and the lower anti-skid 4b each having one fitting piece 10 and one fitting hole 11 are molded separately, and these are formed on the chain links 2 of the cross chain 3 and the respective locking portions 9a. May be connected to the left and right link side pieces 8 of the chain link 2 and the fitting piece 10 may be joined from above and below via an adhesive or the like so as to be fitted in the fitting hole 11. .

The outer side chain 1 is tightened by inserting the other end of the outer side chain 1 into the tightening ring 12 at one end of the outer side chain 1 and then tightening the other end of the outer side chain 1. A tightening spring 13 at the other end of the outer side chain 1 is engaged with an appropriate chain link in the vicinity. According to this, it is possible to obtain an effect that the size of the tire A can be adjusted.

[Effect of device]

 In the tire chain of the present invention, as described above, the metal cross chain 3 having a large number of chain links 2 between the pair of metal side chains 1 mounted on the inside and the outside of the tire A is formed in a hexagonal shape. In a tire chain that is erected at an appropriate interval in a ladder shape or a ladder shape, a non-metallic non-slip 4 such as rubber or plastic is attached to the chain links 2 of all or every one or more of the cross chains 3 in the tire tread. As shown in FIGS. 1 and 2, the cross chain 3 is attached to the tire T of an automobile during snowfall or when the road surface freezes, as shown in FIGS. 1 and 2. Since each skid 4 can prevent skidding, not only can the vehicle run safely from the metal chain, but also the cross chain 3 Each anti-slip members 4 made of non-metallic, it is possible to mute, running noise is quieter than metal chain does not injure the road from and metal chain. In addition, when the brakes are applied during running, the anti-skid 4 of the chain link 2 of the cross chain 3 sinks and the chain link 2 (the twisted substantially elliptical chain link 2 does not slip). Since the chain link 2 provided with the stopper 4 and the straight chain link 2 having a substantially elliptical shape which does not have the anti-slip 4 contact the road surface, the chain link 2 is made of a non-metallic material. Brake is better than the non-slip device.

In addition, by providing the metal cross chains 3 made up of a large number of chain links 2 with all or every other chain links 2 or with a plurality of chain links 2 provided with non-metal cleats 4, respectively. When not in use, each chain link 2 of the cross chain 3 can be easily folded like a metal chain, so the entire unit shrinks compactly, and it is convenient for packing, transporting and storing like a metal chain. Is.

Furthermore, since the non-metallic anti-skid device 4 is provided on all or every one or more chain links 2 of the metal cross chain 3, Due to its simple structure, it can be offered at a lower cost than non-metallic chains.
