Abstract

PURPOSE:To restrain noise generation and damage of a road surface, by forming a gap between the inner peripheral surface of a ring-like body attached circumferentially of a tire and the outer peripheral surface of the tire during attachment thereof, excepting the ground contact sections. CONSTITUTION:A generally ring-like tire slip preventing belt 1 is composed of a ground contact surface 2 and flanges 3 preventing the belt 1 from coming off from a tire T. A gap or clearance 4 is defined between the outer peripheral surface of the tire T and the inner peripheral surface of the tire slip preventing belt 1 during use of the latter. Convexities and concavities 5, etc. are formed, as a slip preventing section, in the ground contact surface 2. The main body of the tire slip preventing belt 1 is composed of, for example, two split halves in order to facilitate the attachment of the belt onto the tire T. With this arrangement the gap or clearance 4 may prevent noise generation and damage of a road surface, and the attachment of the belt onto the tire T may be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial Field of Application The present invention relates to a tire anti-slip belt that is attached to an automobile tire to reduce slippage during driving on snowy roads, frozen roads, muddy areas, sandy areas, etc. It is related to.

('b) Conventional technology Measures to prevent tires from slipping on snowy or icy roads include applying anti-slip measures to the tires themselves (for example, changing the shape and size of the individual blocks forming the pattern). Some are devised (or have spikes), while others have other components added (for example, tire chains). In addition, for muddy or sandy terrain, there are tires with lower air pressure, and tires with larger diameter to increase the ground contact area.

(C1 Problem to be solved by the invention) However, none of the conventional methods has been able to serve as an effective anti-slip means.An effective anti-slip means must first have high anti-slip performance. However, in addition to this, the steering wheel must be operable, the noise must be low, if it is a removable type it must be easy to put on and take off, it must not damage the road surface, and it must be easily compatible with general driving. However, conventional tire chains are difficult to attach and detach, and during normal driving they damage not only the chain but also the road surface, and spiked tires usually cause damage to the chain. Vehicles make a lot of noise when running, and the pollution caused by dust and damage to road surfaces has become a major social problem.

(dl Means for Solving the Problems) Therefore, in view of the above points, the inventor of the present invention has conducted extensive research over many years, and has found that the present inventor has the following advantages: does not damage the road surface, has low noise, is easy to attach and detach, and has a high anti-slip effect. Invented the anti-slip tire belt.

This is installed in the circumferential direction of the tire, and the inner peripheral surface of the ring-shaped main body that covers the outer peripheral surface and part of both side surfaces of the tire and the outer peripheral surface of the tire are at least connected to the area other than the ground contact area when installed. This member is characterized by having gaps in its parts, and is a member that makes it possible to dramatically improve the anti-slip effect by attaching it to general tires. This "gap" has the function of not transmitting the deformation of the tire to the components and increasing the contact area with the road surface, which improves the anti-slip effect, reduces damage to the road surface, and reduces noise. Also suppresses occurrence.

The size of this gap seems to vary depending on the material and structure of the tire anti-slip band, but in the prototype made by the present inventor, it is preferable that the gap is about 3 to 5 squares at the maximum.
If it is less than this, the tire and the tire anti-slip band will work together completely and have no effect, and if it is more than this, noise will be generated and deterioration of the tire anti-slip band will become a problem.

The term "tire" used in this specification generally refers to tires for use in automobiles, motorcycles, etc., but the description will be mainly based on automobiles.

(e) Examples The present invention will be described in detail below based on examples shown in the drawings.

FIG. 1 shows one embodiment of a tire anti-slip belt (1) according to the present invention. As is clear from the figure, the tire anti-slip belt (1) is ring-shaped as a whole, and consists of a contact surface (2) that contacts the road surface and a collar (3) whose main purpose is to prevent the tire from falling off. It is configured.

The flange (3) does not need to cover the entire side surface of the tire, and may be as small as in this example so that it can be easily attached and detached.

Note that the flange (3) does not necessarily need to be provided over the entire circumference.

In this example, the material is a synthetic resin elastic body with a tough cloth built into its inner surface, but any material may be used as long as it exhibits the same effect.

FIG. 2 schematically shows a state in which the tire anti-slip belt (1) shown in FIG. 1 is actually attached to a tire (T). The greatest feature of the present invention is that it plays as shown in the figure (4) during use.
is located between the outer peripheral surface of the tire (T) and the inner peripheral surface of the tire anti-slip belt (1). In addition to the above-mentioned advantages of suppressing noise generation and road surface damage, this also has the secondary effect of making it easier to attach and detach the tire anti-slip belt (1) to the tire (T).

The present inventor prototyped a tire anti-slip belt (1) with a maximum play (4) of 3fi, and as a result of actual running tests,
It exhibited the same anti-slip effect as snow chains on frozen and snowy roads, and did not slip on gravel and sandy roads even under normal tire pressure. This is because tires with spikes and snow chains have almost no anti-slip effect on gravel roads, etc., and the frictional force on the outer surface of the tire anti-slip band (1) is partially larger than the frictional force on the tire surface. It shows that this is not what the theory says. The details of the theory are unknown, but the inventor imagines that the presence of the tire anti-slip belt (1) of the present invention prevents gravel and sand that would be scattered when the tire (T) is in direct contact with the ground. It is thought that this is so that he can be held down without being kicked.

Next, Figure 3 (al and (bl) shows an example in which an uneven part (5) is provided on the surface of the main body as an example in which anti-slip means are added to the ground plane (2) of the main body in order to further improve the anti-slip effect ( Same figure (
a)), and one with a slit (6) cut out (FIG. 2(b)). In experiments conducted by the present inventors, a considerable anti-slip effect was obtained without providing any such anti-slip means, but in reality it is considered more suitable to provide such means.

FIG. 4 shows a tire anti-slip belt (1
) is divided into two halves for easy attachment and detachment. Tire anti-slip belt of this example (1)
As shown in the figure, first place one half of the tire (T) on the upper side, then attach the car to the tire (T) 1/2.
This is done by moving one of the halves by the amount of rotation to bring one of the halves to the ground contact side, and then leaving the remaining halves behind and connecting them.

Naturally, it is also possible to divide the body into three or more parts, and instead of dividing the body into three or more parts as in the previous example, it is also possible to use a method in which the body is fitted by the elastic force of the main body. In addition,
The connection between the divided parts does not need to be strong because almost no tensile force is applied to the connection part, and any method such as a fastener or a hook type may be used. (Not shown) FIG. 5 shows an example of the present invention applied to a double tire. In the case of double tires, 1 as in the previous example.
It may be provided for each tire, or it may be shaped like two tires and may be provided together, as in this example. In this case, the flange (3) is only on one side of each tire (T), and if a connecting part (7) as shown in the figure is provided on the opposing part, the structure will be such that it will not easily fall off. 3)・(3
) can be made with a small (or sometimes no) object that scratches the surface.

(f) Effects of the Invention As explained in detail above, the tire anti-slip band of the present invention is installed in the circumferential direction of the tire, and includes a ring-shaped main body that covers the outer peripheral surface and part of both side surfaces of the tire. The inner circumferential surface and the outer circumferential surface of the tire are characterized by having a gap at least in the area other than the ground contact area when installed, and the presence of the gap suppresses noise generation and road surface damage, and prevents snow-covered roads.・It is extremely useful because it allows safe driving on frozen roads, and it can be easily attached and detached.
