ABSTRACT:
A highly mobile support cart for automotive service personnel presents an elevated support platform over the engine compartment of a vehicle undergoing service. The wheeled frame, ideally supported by a smooth, concrete surface, comprises a rigid, transverse base from which rigid, elongated rails outwardly diverge. The frame mounts an extensible, slightly inclined ladder that supports the work platform. The frame rails and base are equipped with suitable caster wheel assemblies for locomotion. The divergent, reinforced frame design enhances stability and structural integrity. The extensible ladder transported by the frame projects upwardly from the rear. The ladder comprises a lower half pivoted to the frame that telescopingly receives a sliding upper half. Registered locking orifices are pinned by a spring biased clip system to lock the ladder halves against axial displacement. The locking clip comprises a generally C-shaped clasp that is yieldably, spring biased to a locking position. One end of the clasp penetrates aligned locking orifices in the ladder. Ladder orientation is established by a pivotal support brace angularly extending between the frame rails and the ladder. The brace terminates in a lower, transverse foot adapted to be cradled between aligned notches defined in supporting receptacle structure mounted on the frame rails.
