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).

Dependent claims

A body lift for a disabled person comprising:

a frame including a base and a plurality of wheels mounted on said base for permitting movement of said frame;
a first drive means mounted on said frame and operatively connected for imparting rotation to said wheels;
a vertical support extending upward from said base of said frame;
a pair of arm supports and a pair of leg supports movably mounted for translation along said vertical support;
means for operatively connecting said leg supports to said arm support;
a second drive means mounted on said frame and connected to move said arm and leg support pairs along said vertical support;
said leg supports of said leg support pair being laterally pivotable toward and away from each other;
a biasing means connected to urge the leg supports to a normally outwardly pivoted position;
said arm supports of said arm support pair being coupled to pivot the leg supports inward laterally in a substantially orthogonal direction relative to said arm supports in response to weight applied by a user to the arm supports;
and
a control means connected to said first and second drive means for controlling movement of said frame on its wheels and for adjusting the height of said arm and leg support pairs.
