Abstract
A mechanism for controlling and positioning a pivotable handle having lateral axes and extending from the frame of a floor jack, includes a pair of cylindrical discs fixed vertically to the lateral axels, and each has a plurality of radial notches in the periphery thereof. A U-shaped lever arm has each open end pivotally attached to the frame of the floor jack adjacent to and extending generally tangentially to the notched discs; and has a lug projecting toward the discs; and has the U lever handle at the other end extending beyond the rearward end of the frame for actuation by the toe of an operator. The lever arm is pivotable in one direction for engaging the lugs into one of the notches of the discs to fix the position of the handle in a desired angle relative to the frame; and the lever arm is pivotable in the other direction for disengaging the lugs from the notches of the discs so that the handle is free to pivot about the lateral axels.
