Abstract:

A body lift (10) has a wheeled frame (12) and drive motor (42, 44) for moving the frame (12) on its wheels (48, 54). A vertical support (14) extends upward from a base (32) of the wheeled frame (12). Arm and leg support pairs (56, 58 and 78, 80) are movably mounted for translation along the vertical support (14). An elevation motor (28) is connected to lead screw (16) to move the arm and leg support pairs (56, 58 and 78, 80) along the vertical support (14). The leg supports (78, 80) of the leg support pair are laterally pivotable toward and away from each other. A torsion spring (102) is connected to urge the leg supports (78, 80) to a normally outwardly pivoted position. The arm supports (56, 58) of the arm support pair are coupled to pivot the leg supports (78, 80) inward laterally in response to weight applied by a user to the arm supports (56, 58). A control (57) engageable by the user (100) is connected to the motors (28, 42 and 44) to allow the user to move the lift (10) on its wheels (46, 48) and casters (52, 54) and to adjust the height of the arm and leg support pairs (56, 58 and 78, 80).
