Abstract
An anti-skid device for a vehicle wheel is provided comprising an axial part having a plurality of arms extending therefrom which are attached to an anti-skid assembly, such as a snow chain arrangement. The axial part includes a securing device which rotates freely relative to the axial part for securing the anti-skid device to the vehicle wheel. Thus, the rotary motion of the anti-skid assembly around the wheel is not transferred to the securing device.

An anti-skid device for a wheel having an inner rim portion and an outer circumferential portion, comprising;
- an axial part located at an axis of rotation of the wheel;
- said axial part having a securing means facing the wheel for securing said axial part to the inner rim portion and a retaining portion facing away from the wheel;
- a rotation means connecting said securing means and said retaining portion;
- said securing means thereby being freely rotatable about said rotation means relative to said retaining portion;
- a plurality of attaching arms extending from said retaining portion;
- an anti-skid means attached to said attaching arms;
- said anti-skid means being disposed about said outer circumferential portion of the wheel;
- said securing means having a plurality of securing members extending from a central portion;
- said securing members having attaching means disposed at distal ends thereof for attaching said securing members to the inner rim portion thereby drawing said anti-skid means toward the axis of rotation of the wheel and drawing said axial part toward the wheel;
