Abstract

An emergency vehicle traction device for improving the traction of an automobile wheel having laterally communicating hub apertures. The device comprises a traction member preferably comprising a chain for improvement of the wheel's traction, a flexible rope or strap for wrapping around the inside of the wheel and through a hub aperture, and a novel fastener member for holding the traction device in place on the wheel. The fastener member comprises one or more rope binding channels and one or more rope binder adapted to bind a free end of the rope member, and thereby to hold the traction device securely in place. A preferred embodiment of the traction device further comprises a retrieval tool adapted to pass through the hub aperture and to draw the free end of the rope through the wheel by engaging an eye provided on the free end of the rope. No more than two or three traction devices according to the disclosure are needed to move a vehicle out of even the worst predicaments. Traction devices according to the invention are easy and quick to install, and may easily be installed without lying on the ground in the mud, snow, or dirt.

Dependent claims

An emergency vehicle traction device for improving the traction of an automobile wheel comprising a laterally communicating hub aperture and a bearing surface adapted for rolling contact with a driving surface, the traction device comprising:

a traction member comprising a first end, a second end, and a traction enhancing section therebetween;
a flexible rope member attached to said first end of the traction member, the flexible rope comprising a free end;
and
a fastener member attached to the second end of said traction member, the fastener member comprising a plurality of rope binding channels and a plurality of rope binding means adapted for binding said free end of said flexible rope within said channels when said free end is passed through a first binding channel, flexed, and passed through at least one additional binding channel;
whereby, upon passing said free end of said flexible rope member around a bearing surface of the wheel in such manner that a substantial portion of said traction section is disposed across a substantial portion of said bearing surface, through a laterally communicating aperture in a wheel hub of an automobile wheel, and through said fastener member, in such manner as to interpose said traction section between said bearing surface and a driving surface, when said wheel is rotated with respect to the driving surface with said free end bound by said fastener member, traction of said wheel upon said driving surface may be improved.
