Description

ELASTIC RUBBER STRAP WHEELCHAIN FOR AUTOMOBILE}

The present invention relates to a snow chain that is used to attach to the wheels of a vehicle, and it is possible to prevent slippage on ice roads during winter driving. It is in the technical field.

Conventional techniques are largely divided and can be divided into metal chains and non-metal chains according to materials used for fabrication, and the metal chains are prevented from slipping again. According to the shape and structure of the connecting arrangement of the iron rings, the basic units in charge of the technology, the original chains of the four-sided continuous form It can be divided into straight or ladder-like linear arrangement or ZIGZAG-type arrangement. It is a non-metallic chain made of synthetic resin such as rubber or urethane, etc. ) It is made by using a compound as a material, and it is shaped like a round and thin rod, a thin flap, a band, or a tile pad (PAD). A basic unit for preventing slipping and forming a date Shapes, ladders, or ZIGZAG, or NET-shaped structures can be classified and used. Urethane pads are used for each unit pad. It can also be seen that the entire area of the vehicle wheel tread is independent and distributed.

Overall, although many improvements and developments have been made, whether metal or non-metal, there have been parts and breakdowns. A satisfactory solution to problems such as complications of work has not yet appeared.

The present invention did not start under the objective of improving the problems of existing snow chains, but paradoxically it brought about the solution of almost all problems. However, the motivation is the rubber elasticity, which is the principle of my own design, the elastic rubber band hanger for preventing slippery shoes. It is derived from the intention of applying and preventing slippage. In the case of human walking, the elastic rubber band is always placed between the sole of the shoe and the ice, so that slippage is prevented. In the case of driving a vehicle, the elastic rubber body (having an appropriate thickness) is always under the tread part of the wheel of the vehicle because it can be prevented (or the synthetic resin of elasticity). System compound ( The technical task was to find the most rational and practical way of letting go.

As a result of studying the technical problem of the present invention, as shown in Fig. 1, the body of a rectangular elastic rubber strap having a suitable thickness (about: 6-20 mm large car 15-20 mm) The anti-slip base unit is used, and an anti-separation collar {FLAP} is attached to it to attach the elastic rubber-strap chain and The constitution of the invention was completed by taking charge of all the skills involved in the process of dissolution.

Now, let's take a look at the detailed configuration and operation of each of the elastic rubber strap and the escape prevention feather.

Elastic rubber straps are made of elastic rubber with a thickness of 6 to 10 mm (for passenger cars). [At this time, the outer surface of the elastic rubber strap (the side in contact with the ice sheet) has irregularities. The width is equal to the width of the tread portion of the vehicle wheel and the length is equal to the circumference of the vehicle wheel. At this time, the escape preventing feathers are bonded to each other along the length of the rectangular body of the elastic rubber strap as shown in FIG. The body of the elastic rubber strap chain attached to the vehicle wheel prevents slipping by the following actions.

When the vehicle starts to run and the wheels rotate, the body of the elastic rubber strap chain that is pressed under the tread part of the wheels in the stationary state. The upper part is moved upward, and the body of the adjacent part is squeezed as it enters between the wheel and the ice plate. At this time, the parts that are compressed by the force of gravity due to the weight of the body and the reaction force from the ice sheet are deformed. (取: thinner and wider) makes the tread part of the wheel and the ice plate adhere to the surface. It can be seen indirectly as follows that the state integrating and forming this surface adhesion is supported by the high strength generated from the physical deformation.

At any point in time when the vehicle is attached to the elastic rubber strap chain, the elastic rubber strap body is deformed, and the tread portion of the wheel and the ice plate are in close contact with each other. Assume a situation in which the state that caused the integrated integration is stopped as it is, and the force is applied in the horizontal direction in this state. In order to be able to move the vehicle, the elastic rubber strap body of the part that is deforming is intuitively incapable of being broken or melted. I can sense it.

The conditions that can cause rupture or fusion of the elastic rubber strap body in the above situation are difficult to find in relation to normal vehicle operation. Tread part of the wheels, the temperature, and the climatic conditions at the time of operation, and the tread part of the wheel and the ice plate are integrated in surface contact. It can be seen that the place of support is supported by a great force.

From now on, as a final step to identify the anti-slip action of the elastic rubber strap, the tread part of the wheel and the ice plate overlap with the media of the body of the elastic rubber strap. Let's analyze the effect of the forces in the area of 힘들.

First, this part is the working point of the force that the weight of the vehicle is transmitted to the ground through the ice when the vehicle is stationary. When the vehicle starts to move, the wheel acts as a functioning point of the force that acquires the frictional force by applying the force of the rotating wheel there.

Second, when the vehicle is positioned on an inclined ice plate and the vehicle body slides manually, the force to slip down and the force to stop it (: Gravity action of the vehicle body functions as an operating point of the force that continues to collide with the inclined surface.

As seen above, the part retains the strong force supported by the elasticity of the rubber and functions as a functioning point of several forces. During rotational movement, it receives enough force to prevent the idle wheels, and on the sloping surface of the car, As the force continues to surpass the force to slip, the body will not slip.

The following describes the structure and operation of the anti-seizure feather {FLAP}. The release landing target is installed along the length of both sides of the rectangular body of the elastic rubber strap chain (see Fig. 1), and the body of the elastic rubber strap is positioned in the correct position {: Tread part of the wheel ( It provides the function of maintaining the position of the overlapping state without facing the gap, and all functions related to the attachment and release of the elastic rubber strap chain. As a major component that is being received, it is flexible and resistant to tensile strength and is not easily torn. Synthetic fiber cloth or synthetic resin system. Using synthetic artificial leather, film, net, net, etc., the width should be about 30 ~ 60mm, and the length should be the same as the body length of the elastic rubber strap chain. Keep extra lengths so that they can be hooked up. The fabric tunnel (CLOTH) is installed by overlapping the other side of the joint where the separation prevention feather and the body of the elastic rubber strap are bonded together by 3 to 5 mm inward along the length. TUNNEL) (or ring straps with rings of constant length and ends at regular intervals along the joints) is made, and a string of about 2-3 mm in diameter is passed through. At this point, in order to better understand the function and function of the escape guard, the process and method of attaching the elastic rubber strap to the wheels will be examined at the same time. do.

As shown in Fig. 7, the vehicle is moved to the center of the elastic rubber strap chain body by moving the vehicle with the length in front of the wheels of the vehicle to which the elastic rubber strap chain is attached. After positioning, the wheels face each other, and in the sitting position, lift the left and right parts of the body of the elastic rubber strap chain, and the upper part of the tread of the wheel. Overlap in the middle and press to complete the primary connection of the body (see Fig. 4). Subsequently, the two ends of the separation prevention blades (see Fig. 3) facing each other are overlapped, and then the locking button is locked to complete the connection of the elastic rubber strap body. , Hold the one end of the clamping strings at both ends of CLOTH TUNNEL and pull it out 2 or 3 times, so that the escape prevention feather is formed in the outer space of the elastic rubber strap body. The circumference of the circle shape is reduced to the first order. On the other side, the same tips and movements are used to further reduce the circumference of the circle shape and arrange it, and then take the same process from the inside of the wheel. The elastic rubber strap chain is attached by reducing the diameter of the circular shape, which is formed by the separation prevention feather toward the space. The process is terminated and the wheels are confined to the inner side of the body formed by the elastic rubber strap chain body and the escape prevention collar, and the relatively elastic rubber strap body is in the correct position. Will be maintained.

The present invention makes it possible to integrate the complicated structure and shape of a conventional snow chain into an elastic rubber strap body as a unitary body, while also slipping the elasticity of rubber. By using the prevention function for 10 minutes, the function was enlarged and improved, and the attachment and release of the anti-seizure collar was installed. By making the work simple, the users avoid using the winter snow chains or passive consciousness of the snow chains. By disabling this system, it promotes the use of it, making it possible to facilitate the smooth communication of winter traffic, and make traffic safety accidents. It seems to contribute greatly to prevention, and the elasticity of the present invention Rubber strap chains are non-vibrating, trouble-free and durable in addition to lightweight, noise-free, pollution-free, which is the advantage of non-metallic chains. It is expected to be widely used at home and abroad as well as the appearance of products.
