Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire chain mounted on a tire of a vehicle or the like and exhibiting a slip preventing function on a snowy road or the like.

[0002]

2. Description of the Related Art A tire chain shown in FIG. 3 has been known as a commonly used tire chain. As a similar invention, Japanese Patent Application No. 3-62770 tire chain shown in FIG. 4 has been proposed. Further relaxation member (wire)
As a tire chain having a method of tightening, a Japanese Patent Application No. 63-287609 slip prevention device for wheels and a Japanese Patent Application No. 63-169304 simple removable type anti-skid tire have been proposed.

According to the tire chain shown in FIG. 3, an anti-slip member (b10) arranged in contact with the outer circumference of the tire,
A coupling member (b11) that is coupled to one end of the anti-slip member (b10) in the tire width direction at a predetermined interval, and a hook receiver attached to one end of the coupling member (b11). (B12), the latching tool (b13) attached to the other end of the connecting member (b11), and the other end of each of the anti-skid members (b10) in the tire width direction while being separated by a predetermined distance. The non-slip member (b1) is attached by hooking the attached hooking member (b14) and each hooking member (b14).
0) pulling member (b1) for pulling and tightly contacting the outer circumference of the tire
5) and are provided.

However, in order to mount the tire chain on the tire, the tire chain is once attached along the outer circumference of the tire, the vehicle is put on the non-slip member (b10), and then the hook receiving member is attached. The tool (b12) and the latch (b13) must be engaged with each other. However, this engaging work is extremely complicated and time consuming because it is inside the tire (side hidden by the vehicle body), and there is a problem that the work itself is difficult for an inexperienced person. Further, in this work, there is a problem that the clothes are easily soiled by the mud attached to the vehicle because it is inside the tire.

Next, the tension members (b15) are attached by pulling the anti-slip members (b10) by latching the respective latch members (b14). However, the adhesion force to the outer circumference of the tire at this time is the tensile member (b15).
However, when the vehicle travels at a speed higher than a certain level, it is loosened by the centrifugal force and comes into contact with the vehicle.

According to the tire chain shown in FIG. 4, the anti-slip member (b) arranged in contact along the outer circumference of the tire of a vehicle or the like.
1) and a penetrating member (b2) provided at one end of the anti-slip member (b1) in the tire width direction at a predetermined interval.
The latch member (b3) provided at the other end of the anti-skid member (b1) in the tire width direction at a predetermined interval is variably linked to the latch member (b3) and the penetrating members (b2). A string-like loosening member (b4) that penetrates the hollow portion (b8) inside the anti-slip member (b1) in the tire width direction and is led out to the side of the hanging member (b3), and the loosening member (b).
4) A tension member (b) such as rubber or spring provided at the end of (4)
5) is provided.

According to this tire chain, when the anti-slip member (b1) is not integrally formed and does not have a shape that fits the outer circumference of the tire, a slippage during mounting is likely to occur, and the anti-slip member (b1) is manufactured. There is a problem that a mold is required for each tire size and the cost becomes high. In the case of tightening by the loosening member (b4) at the time of wearing, although the adhesion is obtained because the weight is applied and pulled, if it is misaligned and attached to the outer circumference of the tire, further tightening is required after running. There was also a problem.

[0008] A tire chain Japanese Patent Application No. 63-287609 anti-slip device for wheels and a Japanese application No. 63-169304 simple removable type anti-skid device for a tire chain having a method of tightening with a loosening member (wire). There is a problem that the storage cost is poor because the circular base plate that fixes the anti-slip member in a cantilever manner as a component that is indispensable, and the structure becomes more complicated, resulting in higher manufacturing costs. .

[0009]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has a simple structure and a low manufacturing cost, and simplifies the mounting work on a tire and shortens the mounting time. It is also intended to improve safety and adhesion to the tire by duplicating the tightening function of the tire chain by the conventional rubber band and the loosening member (wire) shown in FIGS. 3 and 4.

[Operations and Examples] Operations and examples of the tire chain having the above-described structure will be described in detail.

According to the tire chain of FIG. 1 showing the embodiment of the present invention, in order to mount the tire chain on the tire, once the tire chain is attached along the outer circumference of the tire, the vehicle is moved, The tire is placed on the anti-skid member (1) and the hollow anti-skid member (3). Next, the inner side of the tire (the side hidden by the vehicle body) is tightened by pulling the relaxation member (4) from the outside of the tire (the side not hidden by the vehicle body), and the locking means provided at the end of the hollow member (2). (1
4) are connected.

Next, the other non-slip member (1) is connected to the other end of the non-slip member (1) in the outer circumferential direction by a coupling hook metal fitting (13) provided on the side of the metal fitting (8) in the tire width direction. After engaging with the end portions, the rubber bands (7) are respectively retained on the tire central portion side of the double retaining metal fittings (9). Finally, after pulling out the pulled-out portion of the loosening member (4) to all the hanging members (8) and the double hanging metal fittings (9), the hooks (6) are hooked to the relaxing member (4). Then, the appearance shown in FIG. 1 is exhibited to complete the mounting.

According to the tire chain of the present invention shown in FIG. 1, the tire chains are arranged in contact along the outer circumference of the tire of a vehicle or the like,
A plurality of anti-slip members (1) provided with unevenness (15) and tacks (16) are connected to each other by a fitting (17) and a fitting (12).
And one end of the anti-skid member (1) in the tire width direction is hooked on the end of a hollow member (2) having an elongated tubular shape and fixed at a predetermined interval by a fixing fitting (11). Stop means (14) are provided.

Next, the other end of the anti-skid member (1) in the tire width direction is provided with a retaining metal fitting (8) provided at a predetermined interval, but three or more of the retaining metal fittings are provided. , The hanging metal fitting is a two-stage double hanging metal fitting (9). At this time, all may be the double hook metal fittings (9).

Next, the hollow member (2) is connected to one end of the hollow member (2), and the other end of the hollow member (2) passes through the inside of the hollow anti-slip member (3) arranged in contact with the inside of the hollow member (2) in the tire width direction. A string-shaped slackening member (4) led to the latching metal (8) side is provided, and one end of a spring (5) is joined to the end of the slackening member (4), and the other end A hook (6) is provided at the end of the. FIG. 2 shows a perspective view for explaining the above portion.

According to FIG. 2, since the hollow anti-slip member (3) corresponds to a portion for receiving the load of the tire, it has an independent structure and is replaceable. In addition, considering the load-bearing performance, the steel spiral guide is coated with vinyl, etc., and is also coated with the same material as the tire chain, so that it can respond quickly to deformation of the tire during running and has load bearing capacity. It has a different structure. The hollow anti-skid member (3) is held by coupling fixing fittings (12) provided at both ends in the tire width direction. The hooking means (14) is provided at both ends of the hollow member (2),

The tire chain has the same structure as the tire chain shown in the figure, but in the case of the present invention, the rubber band is slipped and attached to the non-slip member (1).
For the purpose of merely performing the tighter retightening, the tension is sufficiently weak because it engages only the double retaining metal fitting (9), so that even a woman can easily wear it.

[0019]

According to the present invention described in detail above, the following effects can be obtained due to the above configuration.

Since all of the tire mounting work can be performed on the outside of the tire (the side not hidden by the vehicle body), it can be easily carried out by any person, and the mounting work can be simplified and the mounting time can be shortened. Similarly, since the hooking work on the inside of the tire is eliminated, there is an effect that the clothes are not soiled. Further, the string-like slackening member (4) having no elasticity does not loosen even by centrifugal force during running, and the rubber band allows the tire to be retightened smoothly. Furthermore, due to the combined effect of the rubber band and the loosening member (4), it is safe even in the event of an accident such as cutting of one side, and even in an emergency, use of the rubber band (7) only or use of the loosening member (4) only. It also has the effect of being possible.
