Patent ID: 8191864

Claim:
A jack bar comprising: an inner member having a first longitudinal axis, an outer tube, said outer tube having a second longitudinal axis and a first external surface region; a driver, said driver including a first body portion and a second handle portion, said second handle portion being movably coupled to said inner member to urge a translation of said inner member along said second longitudinal axis, said first body portion having a second internal surface region, said second internal surface region being adapted to be disposed adjacent to said first external surface region; a removable fixturing member, said removable fixturing member being operatively coupled to said first body portion and being adapted to urge said second internal surface region into contact with said first external surface region so as to establish a releasable frictional coupling therebetween; an axle member, said axle member having a third longitudinal axis, said third longitudinal axis being disposed substantially orthogonal to said second longitudinal axis, said axle member being supported at first and second bearing surfaces of said body portion, said axle portion being adapted to support a detent member, said detent member being adapted for a pivotal motion around said third longitudinal axis of said axle member; and an elastic device, said elastic device being adapted to urge said detent member through said pivotal motion.
