Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a tire chain that is attached to a tire to prevent the tire from slipping when the vehicle runs on a road such as snow and freezing.

[Prior Art] Conventionally, a tire chain of this type, that is, an inner chain located on one side surface of the tire, an outer chain located on the other side surface of the tire, and the inner chain and the outer chain are frozen at right angles to each of them. When attaching a tire chain consisting of a cross chain that is attached to the tire, jack up the car or lay the tire chain on the road surface to move the car, and connect the connecting metal fittings provided at both ends of the inner chain. I was putting my arm into the fender.

Therefore, the work of attaching and detaching in a cold place is very cumbersome and takes a long time, and the clothes are contaminated.

For this reason, the present inventor has recently developed a tire chain that does not require a car to be jacked up or moved when attaching a tire chain to a tire and does not require connection of an inner chain. In this tire chain, an inner member that engages with an inner side surface that is one side surface of the tire is made of synthetic resin, and an opening is cut out at one end to have a C-shape.

[Problems to be solved by the device]

As described above, when attaching a tire chain to a tire, a tire chain that has a C-shaped inner member made of synthetic resin has been proposed as a tire chain that can be attached and detached while the vehicle is in a normal stopped state. Since the C-shaped inner member made of synthetic resin has an asymmetrical shape while the vehicle is traveling, it has a possibility of causing a spreading action due to centrifugal force and possibly causing a positional shift.

The present invention solves the above-mentioned problems that occur in such a C-shaped inner member made of synthetic resin.

[Means for Solving the Problems]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a C-shaped inner member located on one side surface of a tire and having an opening cut out at one end made of synthetic resin, and an outer chain located on the other side surface of the tire. And between the inner member and the outer chain,
A plurality of belt-shaped cross belts that are curved and follow the curvature of the tire surface and are made of a wear-resistant and flexible material such as synthetic rubber.

[Action]

With the tire chain of the present invention, the vehicle can be attached to the tire without jacking up or moving, the tire can be easily attached to and detached from the tire, and
With the weight of the cross belt connecting the inner member and the outer chain attached to the attached tire chain, the expanding action of the inner member due to centrifugal force is suppressed, and in particular, the position shift at the opening of the inner member with respect to the tire occurs. Without it, the function as a tire chain can be fully exerted.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1, 2 and 3 are an inner front view, a side view and an outer front view in which the tire chain of the present invention is attached to a tire. 1 is an opening 1a made of a fiber reinforced synthetic resin material or the like. The inner member has a C shape and is located on the inner side surface 5a, which is one side surface of the tire 5. The outer chain 2 as a side chain is located on the outer surface 5b, which is the other side surface of the tire 5, and the inner member 1 is attached to one end of the outer chain 2.
A hook 3 is provided at a position corresponding to the opening 1a of the outer chain 2 and the hook 3 is hooked to the other end of the outer chain 2; Is the same as.

One end of the inner member 1 is formed so as to cross the tread surface 5c of the tire 5.
In addition, a plurality of curved cross belts (hereinafter, referred to as U-shaped cross belts) 4 along the curvature of the tire surface, the other ends of which are respectively locked to the outer chains 2, are arranged at equal intervals (eight in the embodiment). ) It is provided. As the cross belt 4, a material such as synthetic rubber or resin having abrasion resistance and flexibility is used, and the weight is reduced as compared with the conventional cross chain.

When the tire chain of the present invention is attached to the tire, the opening 1a of the inner member 1 and the outer chain 2 from which the hooks 3 are removed are set to the front, and the C-shaped inner member 1 is moved from the space between the fender and the tire 5. By dropping the outer chain 2 onto the inner surface 5a and the outer surface 5b of the tire 5, the opening 1a of the inner member 1 and the portion of the outer chain 2 from which the hook 3 is removed respectively correspond to rotation axes of the tire 5 not shown. It can pass through and be located on the inner surface 5a and the outer surface 5b of the tire 5.

Then, while adjusting the cross belt 4 connected between the both ends of the opening 1a of the inner member 1 and the both ends of the outer chain 2 where the hooks 3 are located from the outside of the tire 5 to the normal position, By adjusting the cross belt of the inner member 1 and the outer chain 2, the inner surface 5a and the outer surface of the tire 5 are
5b is installed at the correct position on the concentric circle with the rotary shaft,
The hook 3 of the outer chain 2 is hooked.

In the tire chain thus attached to the tire, the centrifugal force that acts on the lightweight cross belt 4 during traveling of the vehicle can be suppressed to be smaller than that of the conventional metal cross chain. Without applying unreasonable force to the C-shaped inner member to which the cross belt 4 is attached,
Therefore, the tire has a non-slip action on a road such as snow and freezing, and the asymmetrical inner member does not cause a positional deviation with respect to the tire.

When detaching the tire chain of the present invention from the tire, by removing the hook 3 that is hooked on the outer chain 2 and pulling the cross belt 4 connected to the opposite side of the opening 1a of the inner member 1 to the outside, Opening of inner member 1
The part of the outer chain 2 from which the 1a and the hook 3 have been removed passes through the rotation shaft and is lifted obliquely upward, and the part that has come out into the space between the fender and the tire 5 can be removed by pulling it out.

〔effect〕

 The present invention has the following effects.

(A) Since the inner member of the tire is made of synthetic resin and has a C-shape with one end open, the tire chain can be easily attached and detached without jacking up or moving the vehicle. You can

(B) Since the inner member does not need to be connected or removed, it can be attached to or removed from the tire without soiling the clothes in a short time.

(C) Since a U-shaped cross belt made of synthetic rubber or the like is arranged so as to hold the tire surface between the C-shaped inner member and the outer chain, the weight can be reduced as compared with the conventional cross chain, and the running chain is running. , The centrifugal force applied to the asymmetrical C-shaped inner member can be reduced, and the expansion action that occurs in the C-shaped inner member can be suppressed, and the durability of the tire chain including the C-shaped inner member can be reduced. This has the effect of increasing the number of positions and preventing displacement of the C-shaped inner member during traveling, that is, eccentric movement.
