Description

[Detailed Description of the Invention] The present invention relates to a tire chain for preventing slip accidents in automobiles.

Tire chains are extremely effective in preventing slips on snow-covered roads, icy roads, etc., but they are often not used because they are not easy to install, resulting in car accidents. The present invention aims to provide an automobile tire chain that can be easily attached and detached, and will be described in detail below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention, in which two opposing ring-shaped chain parts 1a,
A suitable number of cross chain parts 2 are provided between the ring-shaped chain parts 1b so as to be perpendicular to the ring-shaped chain parts 1b, and the ring-shaped chain parts 1a,
One ring-shaped chain portion 1a of 1b is opened at one location, and flexible wires 4a and 4b are connected to each of the open ends 3a and 3b, respectively. The two flexible wires 4a, 4b are guided through a T-shaped guide tube 5, which has one end 5a branched into a T-shape and the other end 5b fixed to the other ring-shaped chain portion 1b. The two wires guided to one ring-shaped chain side and coming out from the guide tube end 5b are combined (6) to form a loop-shaped wire 3 together with the ring-shaped chain portion 1a, and a locking hook is attached to this wire 3. 7 is attached to it. When the T-shaped guide tube is made of a rigid material, it is desirable that these end portions 5a and 5b have a shape that extends toward the center of the ring-shaped chain portion, as shown in FIG. Also, the portion where the wire enters the guide tube does not necessarily have to branch into a T-shape, but at least these ends 5a and 5b are subject to the tensile force of the chain, so they should have enough strength to withstand this. It requires that. At least the part of the guide tube 5 that comes into contact with the ground must also perform the function of preventing tires from slipping like the other cross chain parts, so it is made of synthetic rubber, plastic, or a composite material of these with metal, ceramic, etc. Alternatively, a metal pipe, metal wire pipe, etc. may be covered with rubber or a composite material such as rubber and ceramic, or an integrated structure may be adopted. Further, as the locking hook, for example, one having a snap spring 21 as shown in FIG. 2 can be used. As shown in FIG. 3, the tire chain of the present invention has a ring-shaped chain part 1a having a flexible wire approximately centered on the guide tube 5, and the other ring-shaped chain part 1 on the upper side.
Pull out the flexible wire sufficiently from the T-shaped guide tube so that b is on the lower side, and spread it on the ground.
Place the car wheels on top. Next, after attaching the ring-shaped chain part 1a so as to cover the wheel (not shown) from the front, when holding the vicinity of the locking ring 7 and pulling the wire 3, the open ends 3a and 3b of the ring-shaped chain gradually open. Approaching T-shaped guide tube end 5
In a, a ring is formed only by the chain portion. On the other hand, the wire 3 that has been pulled out is secured to the appropriate position of the ring-shaped chain portion 1b by the locking hook 7, and is locked by attaching a locking chain band with a hook attached to a rubber ring. Installation of the chain is completed. Desorption is the exact opposite operation to the above. Conventionally, it is difficult to access the inside of the wheel (on the vehicle body side) and it is not possible to see it directly, so it is necessary to manually connect or remove the connecting hook located at the position corresponding to the open ring end in the present application. Therefore, it was very difficult to put on and take off, and it was inevitable that the work posture would be unreasonable and the clothes would get dirty, so it was difficult for elderly and female drivers to put on and take off, and it took a long time. Since all the steps can be done on the front side, it is extremely easy to attach and detach, and has the advantage that anyone can operate it in a short time.
