Description

[Detailed description of the invention] The present invention relates to a tire chain device that wraps around the tires of a vehicle to prevent the tires from slipping during snowy conditions, and particularly relates to a tire chain device that allows the tire chain to be easily attached to the tires. .

Various types of tire chains have been developed to prevent tires from slipping during snowy conditions, but many of the conventional tire chains do not have to be attached to tires by moving the vehicle or by jacking up the vehicle body. The disadvantage was that it was not suitable for working in the cold.

A device disclosed in Japanese Utility Model Publication No. 56-23122 is already known as a device that eliminates the drawbacks of the conventional devices. It is stated that the chain can be easily attached to the tire, and the attachment process is also very simple. They are arranged so that their degrees are opposite, and a considerable number (5 in the example) are arranged in a range where they are not opposite.
Since the structure is equipped with free auxiliary cross chains, if these auxiliary cross chains become entangled with each other or with the side chains, it will take time to untie them, making it unsuitable for work in cold weather. Furthermore, if the side chain becomes twisted due to this entanglement, it is difficult to attach it to the tire, and if the side chain is attached to the tire while being twisted while driving, there is a risk that the chain will break. Furthermore, this product has the fatal drawback that it cannot be attached to the tire if the tire chain is misaligned with respect to the tire.Also, it has a considerable number of auxiliary cross chains, and the hook at the tip of each auxiliary cross chain is Since the hook is hooked onto the side chain ring, there is also the disadvantage that the existence of a hook that easily comes off makes it unstable.

The present invention eliminates the drawbacks of the conventional ones mentioned above, eliminates the need for moving the vehicle or jacking up the vehicle body, and also eliminates the need for the body to crawl under the vehicle body, allowing tire chains to be installed in a short period of time without soiling the body. The purpose of this invention is to provide a tire chain device that can be attached to a tire.

The object of the present invention is to consist of a tire chain and an operating rod used when winding the tire chain around a tire. a first side chain located inside two tires of approximately equal length wound in the circumferential direction at intervals in the width direction of the tires, and located outside the first side chain; It has a second side chain, these both side chains are arranged to be shifted in the longitudinal direction, and the mutually opposing parts of these both side chains are connected by a plurality of cross chains, and the first side Attach the bases of two auxiliary cross chains with locking devices at their tips to the end of the chain that does not face the second side chain,
One of the locking tools is made of a magnet and the other is made of a magnetic material, and an engagement tool that can be engaged with the locking tool is provided at an end of the second side chain that does not face the first side chain. Attachment: A mark is displayed at the longitudinal center of the second side chain to indicate that this area corresponds to the upper end position in the circumferential direction of the tire, and the operating rod is attached to the second side chain to which the auxiliary cross chain is attached. This is achieved by a tire chain device comprising a locking portion that can be engaged with an engaging member at the end of the side chain.

The present invention will be explained below with reference to embodiments shown in the drawings.

FIG. 1 shows a tire chain 1 of the tire chain device of the present invention. This tire chain 1 consists of two substantially equal-length first side chains 2 and second side chains 3 that are wound in the circumferential direction of a tire (not shown) at intervals in the width direction of the tire.

is arranged to be located inside the tire, and the second side chain 3 is arranged to be located outside the tire. The first side chain 2 and the second side chain 3 are arranged offset in the longitudinal direction, and a hook 4 as a locking device is attached to one end of both side chains 2 and 3. Moreover, the hook 4 is attached to the other end.
A ring 5 is attached as an engagement tool that engages with the ring 5.

The mutually opposing portions of both side chains 2 and 3 are connected by a plurality of (8 in the embodiment) cross chains 6, 6, which are perpendicular to both side chains 2 and 3. The crosschains 6 are arranged at equal intervals from each other.

At the end 7 of the first side chain 2 that does not face the second side chain 3, two auxiliary cross chains 8 having substantially the same length as the cross chain 6 are provided.
8 is attached to the base, and a hook 9 as a locking member is attached to the tip of each auxiliary cross chain 8. One of the hooks 9 of these auxiliary cross chains 8 is formed of a magnet or has a magnet embedded therein, and the other hook 9 is formed of a magnetic material. Therefore, by adhering both hooks 9, 9 when the tire chain 1 is not in use, both the auxiliary cross chains 8 may become tangled, and the troublesome task of untangling the tire chain 1 when installing the tire chain 1 on the tire can be avoided. No more work required. The spacing between these two auxiliary cross chains 8, 8 and the spacing between the adjacent cross chains 6 and auxiliary cross chains 8 are approximately equal to the spacing between each cross chain 6, 6, respectively.

Note that the opposing range of both side chains 2 and 3 may be increased compared to the embodiment, and only one auxiliary cross chain 8 may be provided.

At the end 10 of the second side chain 3 that does not face the first side chain 2, two rings 11, 11, which serve as engagement tools with which the hook 9 of the auxiliary cross chain 8 engages, are attached to the cross chain 6. , 6 at intervals equal to the intervals of .

Further, a mark 12 is displayed at the longitudinal center of the second side chain 3 to indicate that this portion corresponds to the upper end position of the tire in the circumferential direction.

Next, the tire chain device of the present invention includes an operating rod 13 in addition to the tire chain 1 described above. As shown in FIG. 2, this operating rod 13 has a linear main body 14 made of metal with a gripping portion 15 formed at the base end thereof, and a gripping portion 15 formed at the distal end of the first side chain 2 of the tire chain 1. A hook 16 as a locking portion that engages with the ring 5 is integrally formed. A rubber ring 17 is attached to the base of the operating rod 13, and by passing the side chains 2, 3 of the tire chain 1 through this rubber ring 17, the operating rod 13 can be removed.
This prevents the item from being lost when stored.
