Description

Tire anti-slip device {A NONSKID APPLIANCE}

The present invention relates to a tire anti-slip mechanism for use in a vehicle or a motorcycle, and more particularly, it is possible to partially mount a tire along a circumference of a tire when driving a slippery place such as a snowy road or an ice sheet, and to easily remove and detach a tire. It relates to a prevention mechanism.

In general, if you ride a motorcycle in winter when the snow is slippery, the friction between the road and the tire trade (tread) directly decreases, making steering adjustment unstable during driving and the braking distance longer than usual. You lose.

Therefore, in order to prevent sliding accidents of snow roads or ice roads, a vehicle snow chain sold on the market is wound around a tire of a motorcycle to drive snow roads or ice roads. Therefore, when applied to a motorcycle, not only does it prevent the tire from slipping properly, but also it is difficult to use it on a motorcycle tire.

Thus, in the related art, in order to solve the above problems, the anti-slip spike belt of Korean Utility Model Registration Application No. 2001-25848 has been proposed. The non-slip spike belt disclosed in the publication is configured to be easily detachable by bolt / nut fastening, which is formed by a plurality of spike means formed on the entire bottom face of the tire when it is mounted on a vehicle or a motorcycle tire. Spike-like protrusions or spike pins) prevent slippery tires by slipping on slippery surfaces while driving.

However, in the aforementioned non-slip spike belt according to the related art, since the spike means are evenly distributed on the entire bottom surface facing the tire trade, the spike means is placed on most of the tire trade when the vehicle is mounted on a vehicle or motorcycle tire. In this case, in the case of a vehicle with a heavy body weight, the spike means are located in most of the tire trades. However, in the case of a motorcycle with a light body weight, the spike means are located in most of the tire trades. In this case, there is a problem in that the riding comfort of the motorcycle occupant is reduced, such as severe vibration and noise generated in the motorcycle body during low speed driving (10Km to 30Km per hour).

In addition, since the anti-slip spike belt according to the prior art is mounted between the spokes and the spokes of the tire wheels, it is difficult to be firmly fixed to the tires, so that the high-speed driving of the motorcycle (50 km to 60 km per hour) or braking is required. Twisting or thrust occurs easily, and thus spike means (spike-type protrusions or spike pins) are out of the trade of the tire, there was also a problem that does not function properly to prevent slipping.

Therefore, the present invention was devised to solve the above problems, the object of the present invention is to increase the fastening force while simple operation during fastening, and to increase the friction between the road surface and tire trade during low and high speed travel or braking, vibration and noise It is to provide a tire anti-slip mechanism that not only significantly lowers, but also enhances the ride comfort of the occupant, and can perform a sufficient anti-slip role without leaving the trade.

Tire anti-slip mechanism according to the present invention made to achieve the above object is a tire anti-slip mechanism that is partially mounted along the circumference of the tire, the non-slip member is installed across the trade of the tire, and the anti-slip member First and second support members fixed to both ends and closely attached to both sides of the tire, respectively, and installed on one side of the first and second support members, respectively, to be coupled or separated correspondingly across the wheel of the tire.
