Abstract
A shuttle for carrying an item includes a shuttle body having a raisable platform, a first motor for moving the shuttle body via wheels, and a pair of oppositely mounted linear actuators for actuating to selectively raise the platform to lift an item, the platform being raised by camming devices that rotate around horizontal axes. Other shuttles include a shuttle body having a raisable platform and wheels, the wheels being mounted to the shuttle body on axles coaxial with tubes, a first motor operatively interconnected with the axles for moving the shuttle body via the axles and wheels, and at least one actuator operatively interconnected with the tubes for rotating the tubes relative to the shuttle body to move the platform relative to the shuttle body.
Claims29
A shuttle for carrying an item, the shuttle comprising:
- a shuttle body having two ends and two lateral sides;
- two axles extending across the shuttle body between the lateral sides;
- wheels mounted to the axles outside the shuttle body;
- a motor within the shuttle body for driving the wheels via the axles to move the shuttle body;
- tubular members rotatably mounted about the axles within the shuttle body;
- camming members attached to each tubular member;
- a platform sized to cover the shuttle body and to receive and carry the item;
- and
- at least one actuator within the shuttle body operatively interconnected with the tubular members, actuation of the at least one actuator moving the platform relative to the shuttle body via movement of the tubular members and camming members.

A shuttle for carrying an item, the shuttle comprising:
- a shuttle body having two ends and two lateral sides;
- wheels rotatably mounted to the shuttle body;
- a motor for driving the wheels to move the shuttle body;
- a platform sized to cover the shuttle body and to receive and carry the item;
- a pair of linear actuators located within the shuttle body, each linear actuator having an actuation rod with a distal end extending outward from a central area of the shuttle body toward a respective end of the shuttle body, the linear actuator capable of moving the actuation rod between a retracted position and an extended position;
- a pair of elongated members rotatably attached to the shuttle body between the lateral sides;
- two camming members attached to each elongated member, each camming member being attached to the respective elongated member adjacent a respective lateral side of the shuttle body;
- and
- a connector attached to the distal end of each actuation rod and a respective elongated member, movement of the actuation rods from the retracted position toward the extended position lifting the platform relative to the shuttle body via movement of the connector, elongated members and camming members.

A shuttle for carrying an item comprising:
- a shuttle body having a raisable platform, a first motor for moving the shuttle body via wheels, and a pair of oppositely mounted linear actuators for actuating to selectively raise the platform to lift an item, the platform being raised by camming devices that rotate around horizontal axes.
