ERGONOMIC LIFTING AND LOWERING MECHANISM FOR APPARATUSES FOR ASSISTING A HANDICAPPED PERSON

摘要

An ergonomic, power-assisted lifting-lowering unit for lifting or lowering a user, such as a disabled person. The lifting-lowering unit includes a body-holder, adapted to firmly hold/support at least at one body member/section of the torso of the user; a lifting-lowering-mechanism; a motion and force transmitting mechanism; and a power activator. The lifting-lowering-mechanism includes a power actuator that is operatively engaged with the body-holder, at preconfigured locations. The power activator activates the power actuator to thereby set in motion the motion transmitting mechanism that causes the body-holder to move in a path closely approximating to the movement of the femur bones, or a in path parallel thereto, when the user is moving between a standing position and a sitting position, the knees being the proximal center of the pivotal motion of the femur bones of the user.

主权项

1. An ergonomic lifting-lowering unit for lifting and/or lowering a user, such as a disabled person, the power-assisted lifting-lowering unit comprising:
a) a body-holder adapted to firmly hold or support the torso of the user at least at one body member and/or body section of the torso; b) a lifting-lowering-mechanism comprising:
i) at least one power actuator, wherein said power actuator is operatively engaged with said body-holder, at preconfigured locations; andii) a power providing member for operating said power actuator; c) a motion and force transmitting mechanism; and d) a power activator,wherein said power activator is in operational communication with said power actuator to thereby set in motion said motion transmitting mechanism that causes said body-holder to move in a path closely approximating to the movement of the femur bones, or a in path parallel thereto, when the user is moving between a standing position and a sitting position, the knees being the proximal center of the pivotal motion of the femur bones of the user.
