Abstract: A tightening system (135) for use with anti-skid and traction devices for wheeled vehicles comprising a sealed tightening mechanism (130) which can clutch and ratchet the rotational movement applied by the user on a knob (212). The system further comprises at least one connection assembly (134) which is adapted to be pivotably and releasably attached to a proximal end of a surface contact member (63;71) and which is adapted to be connected to the tightening mechanism. The tightening mechanism comprises a locking component (193) which has a base plate (240), an inner sidewall (195) and an outer sidewall (194) standing perpendicular to said base plate (240). The inner sidewall recessed portion has a plurality of recess (230;231) which are adapted to engage with a peripheral projection of the upper clutch (206) for holding the knob in place during locked and unlocked positions of the knob.

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.

Abstract: An auxiliary pulling apparatus for attachment of the two ends of a flexible retaining ring of an anti skid device is disclosed. The auxiliary pulling apparatus comprise a first attachment means at its first end and a rope portion connected to the first attachment means. The auxiliary pulling apparatus is characterized by a mass which is connected to the second or outer end of its rope portion. The mass is preferably spherical in shape and rotatably connected to the rope portion. The mass maintains centrifugal forces when thrown towards the inner part of a vehicle and keeps the rope portion tight and straight. The user releases the auxiliary pulling apparatus off the anti skid device upon securing the first and second ends of the retaining ring.
