| 20120112143 | Lifting Apparatus - One disclosed lifting apparatus includes a base, a receiving portion, first and second arms, and a support. The base has a proximal end, a distal end, and first and second opposed sides. The first side has a plurality of receiving areas spaced apart between the proximal and distal ends. The arms are rotatably coupled to the base for movement between lowered and raised positions, and are coupled to the receiving portion. The receiving portion is relatively near the base distal end when the first and second arms are at the lowered position, and the receiving portion is relatively distant to the base distal end when the first and second arms are at the raised position. The support rotatably extends from the first arm and automatically engages at least one of the receiving areas when the first and second arms move from the lowered position to the raised position. | 05-10-2012 |
| 20100258775 | Automatic Rising Jack Stand - Jack stands having support arms that automatically rise to meet lifted loads are disclosed herein. According to one embodiment, a jack stand includes a base having a collar, a support arm, a locking mechanism, and a lifting mechanism. The support arm is movable within the collar and has a plurality of teeth defining grooves and ridges. The locking mechanism has a handle and a stopper and is rotatably coupled to the base at an axis of rotation for movement between a first position where the stopper engages at least one of the grooves to restrict the support arm from moving downwardly, and a second position where the support arm is movable upwardly and downwardly. The lifting mechanism is coupled to the base and is in communication with the support arm to automatically raise the support arm relative to the collar when the locking mechanism is moved to the second position. | 10-14-2010 |
