Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Application on WitI The present invention relates to a tire chain for double tires used during snowfall.

(b) Conventional technology Conventional tire chains for double tires consist of a ladder-like double chain consisting of two inner and outer side chains having a cross chain with the length of the double tire contracted length, and a triple chain at the center of the inner and outer sides. The cross chain consists of a tire chain called a triple chain, in which the center side chain is attached with the positions alternately shifted from inside to outside. belongs to.

(c) Problems to be solved by the invention Conventional tire chains for double tires with a shape called a double chain used a cross chain with a length equal to the width of the double tires, so when worn and driven, it would look like a skipping rope. Because the cross chain spreads due to centrifugal force, it could hit the car body, and if the cross chain broke, it would become whip-like due to its length and become entangled with the car body, causing damage to one car body. .

Also, in order to prevent the cross chain from becoming long and whip-like even if it breaks, there is also a ladder-like tire chain made by shifting the left and right sides of the cross chain, which is currently called a triple chain. However, since there are three side chains and they are fixed by the central side chain, it is possible to prevent the rope from flying due to centrifugal force while driving.
There was a problem that it was inconvenient to install.

The conventional tire chains described above are installed by laying them on the road surface and moving the car, jacking up the car, or placing the tires on a pillow. Vehicles equipped with double tires range from small trucks to large trucks and omnibuses, and in the case of large vehicles, they were often installed by placing them on or laying them on top of a tree, without using the jack-up method. These can be installed on stable ground such as snow-free concrete roads, but when the road is frozen or snowy, there is a danger that the tree may slip and fly out, causing property damage or serious injury if it hits someone. In addition, during snowy conditions, snow gets into the gap between the tires of the double tires, so it takes a lot of time to attach the conventional tire chains for double tires, especially those with a side chain in the center.

(d) Means for Solving the Problems The present invention provides a tire chain that can be installed without using jacks or pillows, without moving the vehicle, and that can be installed even under adverse snowy conditions. be.

The basic structure is a ladder-like tire chain consisting of a three-speed side chain. A locking device is provided at one end of the side chain, the cross chain at the other end is fixed only to the inner side chain part, and the center It was confessed that a through ring was installed in the side chain and the part that attaches to the outside side chain, and one side of the side chain that did not have a locking device was attached to a cross chain that was one length longer than a normal tire chain. The long side chain can be used to easily pass the inside of the double tire or through the gap, making it easy to install. Since the side chain is locked and fixed to a locking tool provided at one end of the side chain, it can be installed without having to move or jack up the vehicle.

A through ring is used to lengthen one end of the side chain and to make it similar to normal cross chain attachment.The shape may be a large circle or a double circle, and the shape is such that the side chain can pass freely through it. It is fine as long as it is something. The through ring is installed so that it will fall diagonally when installed, and when the side chains are assembled at right angles, it will not shift between the side chains while driving.

(e) Embodiments In the claims of the present invention, a cross chain provided with a basic through-ring can be installed in the direction of the locking device of the inner side chain and the outer side chain, or in the opposite direction, depending on the difference in position. The patent claims include a structural change due to the difference in how the central side chain is shifted, the inner and outer side chains, a new triple chain or loss chain connection structure, and a new attachment structure of the center side chain. It is something.

This will be explained by showing the structure in the drawings for each claim. 1st
The figure shows the structure of claim 1, and relates to a ladder-like tire chain in which the left and right cross chains of the triple chain are attached alternately by shifting their positions.

Since the number of connectors used in the cross-chain connection from both sides to the central side chain as shown in claims 3 and 4 can be reduced by half, the weight can be reduced.

In addition, the locking tool in the present invention is not limited to the so-called duck shape, but may be a zero-shaped locking tool, and other shapes are arbitrary.

(F) Effects of the Invention It is very time-consuming to attach a tire chain to a single tire, but since there are many large vehicles with double tires, the weight of the tire chain itself is considerable. Moreover, due to the nature of tire chains, they are forced to be used under adverse conditions such as when it is snowing, and working outdoors when it is snowing is extremely difficult and laborious. Particularly for those who drive long-distance transport trucks, installing tire chains is as simple as possible, as they are nervous about driving on snowy roads and are also fatigued by long hours of driving. We desire things, and that also leads to safe driving. In view of these circumstances, the present invention provides a tire chain that can be smoothly attached even under snowy conditions without moving the vehicle while getting on and off the vehicle.
