Abstract
A lug wrench apparatus comprising a collet-type assembly whereby the socket clamps to the lug nut in a manner similar to the way a collet clamps a router bit. The clamping mechanism can be provided either by a screw-compression, or an eccentric cam compression. Arbitrarily large amounts of torque can be applied by means of an extension which fits over the arm of a wrench that is clamped to the shaft of the collet.
Claims5
An apparatus for removing and tightening nuts, including lug nuts on vehicular wheels comprising:
- a hexagonal socket having a tapered internal diameter and having longitudinal slits that provide flexion of the faces of the socket;
- a compression sleeve having a portion with a larger tapered internal diameter that is adapted to receive the hexagonal socket;
- a wrench having a handle adapted to receive extensions, the wrench having an engagement end that drives the hexagonal socket;
- a compression thrust washer that locks the wrench, compression sleeve and hexagonal socket together;
- wherein the wrench is a closed end wrench and is captured between the compression sleeve and the compression thrust washer;
- and
- a lever having an eccentric cam that pivots on a transverse pin through the posterior end of a threaded rod which threadedly engages a threaded hole in the posterior end of the socket.
