Publication number: 20020008231Abstract: A vehicle jack adapted to be mounted to a vehicle chassis is provided. In one embodiment, the jack comprises a base member, a guide member, a flexible rod, and an actuator. One end of the rod is fixedly attached to the base member while a second end is slideably disposed within a passageway defined by the guide member. The actuator forces the flexible rod to deform by causing the second end of the rod to move with respect to the passageway. When mounted to a vehicle chassis, the jack is operated by deforming the flexible rod until a support surface, such as the ground, is encountered, and subsequently continuing to deform the rod until the vehicle becomes elevated. A vehicle jacking system incorporating the jacks of the invention is also provided.Type: ApplicationFiled: July 12, 2001Publication date: January 24, 2002Inventors: Andrew Zachary Glovatsky, Robert Edward Belke, Jay DeAvis Baker, Joseph Mario Giachino, Lakhi Nandlal Goenka, Myron Lemecha
