ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention is related to an improvement in the structure of an anti-skid device for vehicle tires and in particular to one which can be rapidly and securely attached to a vehicle tire.
2. Description of the Prior Art
An anti-skid device must be used on vehicle tires in order to drive on a roadway during inclement weather conditions. However, it has been found that installing and removing conventional anti-skid devices from vehicle tires in inclement weather conditions can be dangerous and difficult. The conventional anti-skid device includes two side arms and a plurality of nets arranged between the two side arms which are generally made from resin or synthetic rubber. The nets are transversely connected together by means of linking rings. However, when in use, the tire must be first lifted by a jack in order to place the anti-skid device under the tire and then the tire is lowered after mounting the anti-skid device. Alternatively, the anti-skid device is first placed on the ground, the vehicle is driven forward or rearward to position the tire on the anti-skid device, and then thereafter the anti-skid device is moved upwardly to enclose the tire. Nevertheless, such operations are very tiresome, especially in winters, thereby making the conventional anti-skid devices unfit for practical use.
Therefore, it is an object of the present invention to provide an improvement in the structure of an anti-skid device for vehicle tires which can obviate and mitigate the above-mentioned drawbacks.
SUMMARY OF THE INVENTION
This invention is related to an improvement in the structure of an anti-skid device for vehicle tires.
It is the primary object of the present invention to provide an improvement in the structure of an anti-skid device for vehicle tires which can be easily and securely mounted on a vehicle tire without using a jack or moving the vehicle.
According to a preferred embodiment of the present invention, an anti-skid device for vehicle tires includes a plurality of flexible net treads connected together by linking rings each of the net treads being provided with a net pattern at an intermediate portion and two pairs of slant arms, an upper portion of each of the net treads having a transverse grip which is shorter than width of a tire, anti-skip members being provided on appropriate positions of the net treads so as to further increase anti-skid ability of the anti-skid body, side arms mounted between outer ends of the slant arms, end arms connected with inner ends of the slant arm, and linking members connecting the end arms to the net treads, the slant arms extending outwardly from the transverse grip, distance between the slant arms being equal to the largest width of the anti-skid body.
The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts. Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
