CENTRAL TIGHTENING SYSTEM FOR ANTI-SKID DEVICES AND AN ANTI-SKID DEVICE HAVING THE SAME
First Claim
1. A tightening system for use in anti-skid and traction enhancement devices, comprising:
- a central node (111, 112, 113) which is located on a principle axis of an axle of a wheel, said central node having a plurality of extensions adapted to fasten and tighten a plurality of radially extending straps around a periphery of said central node and being free of any connection to the wheel; and
a plurality of radially extending flexible straps, which are attached to a surface contact member (79) at their first ends and to said central node (111, 112, 113) at their second ends, wherein said flexible straps are bent and passed through a corresponding buckle (32) for tightening said surface contact members in a radial direction whereinsaid straps are provided with ratchet teeth (30) along at least one of their surfaces, andsaid buckle (32) has a driving thumb (36) which, when pulled in a first direction, adjusts a tightness of each strap and said each strap is prevented from reverse movement by a tooth (38) and a pawl (37) of said buckle (32).

Abstract
A tightening system of straps for use in anti-skid and traction enhancement devices is disclosed. The tightening system comprises a central node which is located on the principle axis of the axle of a wheel and which has a plurality of extensions adapted to fasten a plurality of radially extending straps around its periphery. A plurality of radially extending flexible straps, which are attached to a surface contact member at their first 10 ends and to the central node at their second ends, are used to tighten the anti skid device. The flexible straps are passed through a buckle for tightening the surface contact members in the radial direction in order to eliminate outward bulging on the surface contact members as well as to avoid eccentricity in the strap system.
