Abstract

A friction lock bar jack for lifting items including an elongated bar having a distal end and a proximal end, a lifting mechanism reciprocally slidably carried by the elongated bar and including a toggle mounting body, an actuating lever pivotally coupled to the toggle mounting body and movable between a neutral position and a drive position and a toggle mechanism to frictional engage the elongated bar and move the toggle mounting body incrementally toward the distal end with the actuating lever in the drive position, and freely movable along the elongated bar with the actuating lever in the neutral position. A locking assembly is received about the elongated bar and carried by the lifting mechanism to selectively prevent movement of the lifting mechanism toward the proximal end and allow movement toward the distal end.
