Mobility system including an exoskeleton assembly releasably supported on a wheeled base

A mobility system for providing mobility assistance to a user, the system comprising a wheeled base, an exoskeleton assembly, and a docking assembly arranged to selectively support the exoskeleton assembly on the wheeled base, the wheeled base comprising a base frame and wheels supporting the base frame for rolling movement along the ground and the exoskeleton assembly comprising:

• an upper portion arranged to be braced to a torso of a user;
• an intermediate portion arranged to be braced to thighs of the user;
• a hip joint pivotally coupling the intermediate portion to the upper portion;
• a lower portion arranged to be braced to lower legs of user;
• a knee joint pivotally coupling the lower portion to the intermediate portion;
• whereby the exoskeleton assembly is configured to provide a walking, motion to the user;
• the docking assembly being operable between a coupled position in which the exoskeleton assembly is coupled to the wheeled base and the exoskeleton assembly is movable relative to the wheeled base between respective standing and sitting positions and a released position in which the exoskeleton assembly is readily separable from the wheeled base in the standing position of the exoskeleton assembly;
• and
• a seating surface providing sole sifting support to the user seated thereon in the sitting position of the exoskeleton assembly, the seating surface being supported on the intermediate portion of the exoskeleton assembly for separation from the wheeled base together with the exoskeleton assembly in the released position of the docking assembly, the seating surface being adapted to move with the intermediate portion of the exoskeleton assembly when the exoskeleton assembly provides said walking motion to the user.

A mobility system for providing mobility assistance to a user, the system comprising a wheeled base, an exoskeleton assembly, and a docking assembly arranged to support the exoskeleton assembly on the wheeled base such that the exoskeleton assembly is movable relative to the wheeled base between respective standing and sitting positions, wherein:

• the wheeled base comprises a base frame and wheels supporting the base frame for roiling movement along the ground;
• the exoskeleton assembly comprises:
• an upper portion arranged to be braced to a torso of a user;
• an intermediate portion arranged to be braced to thighs of the user;
• a hip joint pivotally coupling the intermediate portion to the upper portion;
• a lower portion arranged to be braced to lower legs of user;
• and
• a knee joint pivotally coupling the lower portion to the intermediate portion;
• the lower portion of the exoskeleton assembly comprises two independent lower leg members arranged to be braced to respective ones of the lower legs of the user;
• the docking assembly comprises a pair of lower docking members arranged to be coupled to respective ones of the two lower leg members independently of one another, each lower docking member comprising an extensible link in the coupled position of the docking assembly which is extendible in length between the exoskeleton assembly and the wheeled base;
• and
• the extensible links are independently extendable relative to one another such that the lower docking members are arranged to remain coupled between the wheeled base and the exoskeleton assembly during a walking motion of the exoskeleton assembly.
