Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tire anti-slip device that is attached to the outer periphery of a tire to prevent the tire from slipping on icy and snowy roads.

[Prior Art] Tire anti-slip devices that are attached to tires on snow-covered roads to improve the performance of vehicles on snow have long been used with a main body made of a metal chain. Tire anti-slip devices whose bodies are made of materials such as rubber or flexible polymers have become popular because they are heavy and difficult to handle.

In a tire anti-slip device whose main body is made of a material such as rubber or a flexible polymer, the main body is attached to a tire in a pressed state using an elongated fastener and an external attachment device.

The fastening tool is arranged on the inner side surface of the tire by connecting the ends of flexible elongated materials such as fiber ropes or wire lobes in an annular manner via a connecting means, and is attached to an outer mounting tool arranged on the outer side surface of the tire. Tension is generated by tightening, and the outer fitting presses the main body against the tire.

As shown in FIG. 10, the connecting means of the fastener is a rope disposed on the inner side of the vehicle (left side in FIG. 10) on one side in the width direction of the tire anti-slip device main body 102 of the tire anti-slip device 100. A tire slip prevention device 100 is generally provided with a hook 106 latched to one end of the lobe 104 and an eye 108 formed at the other end of the lobe 104.

However, in this connection means, when the hook 106 is locked to the eye portion 108, both the hook 106 and the eye portion 108 are located on the inside side of the vehicle, which is the opposite side to the tire side surface facing the outside of the vehicle. Since both are small, it is necessary to insert both hands deep inside the vehicle and feel around to bring the tip 106A of the hook 106 into the frame of the eye 108 to lock them together. It took a long time to lock it.

[Problems to be Solved by the Invention] In consideration of the above facts, an object of the present invention is to provide a tire anti-slip device that can improve the workability of attaching the tire anti-slip device to a tire.

[Means for Solving the Problems] The present invention provides a tire slip prevention device main body that is wrapped around the tire by winding it around the tire and connecting both ends in the longitudinal direction, and a tire slip prevention device main body that is wound around the tire by winding it around the tire and connecting both ends in the longitudinal direction.

An intermediate portion of a hook 44 serving as a locking portion is locked to this loop portion 42A. A base end portion 44A of the hook 44 is engaged with the small frame portion 32 to support the hook 44 on the tire anti-slip device main body 12.

As shown in FIG. 2, this hook 44 has a screw hole 46 formed at its tip 44B facing in the width direction of the tire anti-skid device main body 12. A male threaded portion 50 formed at the tip end 48A of the guide body 48 is screwed into the threaded hole 46, so that the hook 44 and the guide body 48 are integrated.

The guide body 48 is made of a material with high torsional rigidity, such as steel wire. The tip of this guide body 48 is extended to the other side (right side in FIG. 1) of the tire anti-slip device 10 to form an insertion base 48B.

As shown in FIG. 1, an eye portion 42B serving as a locking portion is formed at the other end of the lobe 42.

This loop-shaped eye portion 42B is inserted from the insertion base 48B of the guide body 48, guided in the longitudinal direction of the guide body 48, and engaged with the hook 44. This hook 44 has a bent portion 44C projecting toward the eye portion 42B between the base end 44A and the other end 44B.
is formed so that it does not come off the eye portion 42B.

Next, a procedure for attaching the tire slip prevention device 10 of the present invention to a tire 37 as shown in FIG. 3 will be described.

First, as shown in FIG.
4 (in the direction of the arrow in FIG. 2), screw the male threaded portion 50 of the guide body 48 into the screw hole 46 formed in the hook 44
and the guide body 48 are connected. Then, the tire anti-slip device main body 12 is placed over the outer periphery of the tire 37 so that the side on which the lobe 42 is arranged corresponds to the vehicle inner surface of the tire 37. Next, the rubber ring 39 is appropriately selected 2.3
