Abstract
An expandable car jack including a base with a first base extension member and a second extension member rotatably, removably, and directly coupled to one another, the first and second base extension members operably configured to rotate with respect to one another to define a planar lower support surface forming an x-shape or a substantially perpendicular configuration. The expandable car jack may also include a plurality of hinged members supported by the base, wherein the plurality of hinged members define a lifting surface and are coupled together with a screw, the screw operably configured to rotate, expand and contract a width separating the plurality of hinged members, and place the lifting surface at a plurality of raised height positions.
Claims14
An expandable car jack comprising:
- a portable base and a vehicle lifting assembly coupled to one another, the vehicle lifting assembly having a lifting surface and operably configured, through at least one of a threaded screw-hinge configuration and pneumatic force, to place the lifting surface at a plurality of raised height positions with respect to a lower support surface, opposing the lifting surface, of the base, the base including:
- a first base extension member having a planar lower surface, a proximal end, a distal end, and a first member length separating the proximal and distal ends of the first base extension member;
- a second base extension member coupled to the first base extension member and having a planar lower surface, a proximal end, a distal end, and a second member length separating the proximal and distal ends of the second base extension member;
- a first position along a base expansion path with the first and second base extension members in a vertically-stacked overlapping and substantially parallel configuration with one another where the planar lower surface of the first base extension member and the planar lower surface of the second base extension member are non-coplanar with one another;
- and
- a second position along the base expansion path with the first and second base extension members in overlapping and substantially perpendicular configurations with one another where the planar lower surface of the first base extension member and the planar lower surface of the second base extension member are coplanar with one another.

- operably configured to rotate with respect to one another from a vertically-stacked overlapping and substantially parallel configuration with one another where the planar lower surface of the first base extension member and the planar lower surface of the second base extension member are non-coplanar with one another, to an overlapping and substantially perpendicular configuration with one another where the planar surface of the first base extension member and the planar surface of the second base extension member are coplanar with one another, forming an x-shape;
- and
- a plurality of hinged members supported by the base, defining a lifting surface, and coupled together with a screw, the screw operably configured to rotate, expand and contract a width separating the plurality of hinged members, and place the lifting surface at a plurality of raised height positions.

An expandable car jack base comprising:
- a base with a first base extension member and a second base extension member rotatably, removably, biasedly, and directly coupled to one another with a fastener and a spring, at least one of the first base extension member and the second base extension member having side walls defining a recess thereon and the first and second base extension members operably configured to rotate with respect to one another about the fastener along a base expansion path to reach a locked position, forming an x-shape, with the other of the at least one of the first base extension member and the second base extension member disposed within the recess and restricted from rotational movement by at least one of the side walls of the at least one of the first base extension member and the second base extension member, each of the first and second base extension members having a planar lower surface;
- and
- a plurality of hinged members supported by the base, defining a lifting surface, and coupled together with a screw, the screw operably configured to rotate, expand and contract a width separating the plurality of hinged members, and place the lifting surface at a plurality of raised height positions, wherein
- the planar lower surface of the first base extension member and the planar lower surface of the second base extension member are coplanar with one another in the locked position.
