Patient lifting and rehabilitation device

A lift device system comprising:

• a lift device including
• two vertical extendible tower members supporting a horizontal extendible transverse member further including
• a horizontal extension assembly configured to extend and retract the horizontal extendible transverse member in a horizontal direction perpendicular to a vertical direction,
• a traveler carriage configured to move in the horizontal direction upon the horizontal extension assembly between the two vertical extendible tower members,
• the horizontal extension assembly further including
• a first pair of telescopic slides attached to a left horizontal end structure and the traveler carriage, the first pair of telescopic slides defining a first plane being substantially diagonal to a longitudinal axis of the traveler carriage;
• and
• a second pair of telescopic slides attached to a right horizontal end structure, the second pair of telescopic slides defining a second plane being substantially diagonal to the longitudinal axis of the traveler carriage and substantially orthogonal to the first plane, and
• an omnidirectional wheel assembly configured to translate and rotate the lift device, and
• a payload lifting device configured to raise and lower a payload with respect to the horizontal extendible transverse member and translate the payload in a horizontal direction between the two vertical extendible tower members;
• a navigation control system configured to provide navigation control to the lift device when the omnidirectional wheel assembly is operating;
• an extension control system configured to provide extension control to the two vertical extendible tower members and the horizontal extendible transverse member;
• and
• a user-interface system configured to receive input from and provide feedback to an operator.

A method of operating a lift device, the method comprises:

• providing a lift device including
• two vertical extendible tower members supporting a horizontal extendible transverse member,
• an omnidirectional wheel assembly configured to translate and rotate the lift device,
• a payload lifting device configured to raise and lower a payload with respect to the horizontal extendible transverse member and translate the payload in a horizontal direction between the two vertical extendible tower members;
• and
• extending the horizontal extendible transverse member along two pairs of telescopic slides, wherein
• a first pair of telescopic slides are attached to a left horizontal end structure of the horizontal extendible transverse member and a traveler carriage, the first pair of telescopic slides defining a first plane being substantially diagonal to the horizontal direction, the first pair of telescopic slides attached from the left horizontal end structure to an upper portion of a first side and to a lower portion of an opposite second side of the traveler carriage, and
• a second pair of telescopic slides are attached to a right horizontal end structure of the horizontal extendible transverse member and the traveler carriage, the second pair of telescopic slides defining a second plane being substantially diagonal to the horizontal direction and substantially orthogonal to the first plane defined by the first pair of telescopic slides, the second pair of telescopic slides attached from the right horizontal end structure to an upper portion of the opposite second side and to a lower portion of the first side the traveler carriage;
• and
• translating the payload lifting device on the traveler carriage within a range motion between the two vertical extendible tower members.

A lift device comprising:

• a horizontal extendible transverse member including
• a first horizontal end structure at a first distal end of the horizontal extendible transverse member, and an opposite second horizontal end structure at a second opposite distal end of the horizontal extendible transverse member, each horizontal end structure configured to be connected to a vertical support structure;
• a traveler carriage configured to move in a horizontal direction upon the horizontal extendible transverse member and lift a payload in a vertical direction;
• and
• a telescopic slide assembly configured to connect the first and the opposite second horizontal end structures by
• a first pair of telescopic slides attached to the first horizontal end structure and the traveler carriage, the first pair of telescopic slides defining a first plane being substantially diagonal to the horizontal direction;
• and
• a second pair of telescopic slides attached to the opposite second horizontal end structure and the traveler carriage, the second pair of telescopic slides defining a second plane being substantially diagonal to the horizontal direction and substantially orthogonal to the first plane defined by the first pair of telescopic slides.
