ABSTRACT:
A lift jack is provided for use with a vehicle having a structural member on the underside of the vehicle, which structural member defines a transverse rotational axis. An elongated body member defines a longitudinal axis, and has a top end portion and a bottom end portion. The longitudinal axial length of the elongated body member is greater than the height of the transverse rotational axis above the ground. The bottom end portion has a radiused lifting surface and a generally planar foot extending contiguously from the radiused lifting surface, toward a second lateral edge of the bottom end portion. The elongated body member may be rotationally mounted on the vehicle by attachment of the top end portion to the structural member. The elongated body member may in this manner be rotated about the transverse rotational axis from a stored position, through an initial deployed position, wherein the radiused lifting portion contacts the ground; and thence on to a fully deployed position, wherein the foot portion contacts the ground and the longitudinal axis of the elongated body member is substantially aligned with the true vertical direction, so as to lift the vehicle above the ground. The motive force of the vehicle is preferably used to accomplish rotation of the elongated body member from the initial deployed position to the fully deployed position.
