Patent ID: 7082644

Claim:
A handle extension for rotating a crank handle, the crank handle having a base portion with a rotational axis, a body portion that extends at an angle from the base portion, and a bent gripping portion that extends at an angle from the body portion and is axially offset from the rotational axis of the base portion, the handle extension comprising: an elongate shaft having an axis, a first end and a second end; a member fixedly secured in a transverse plane across the first end of the shaft, the member having a receptacle defined in the transverse plane to receive in close fitting relation the crank handle with the axis of the shaft in substantial axial alignment with the rotational axis of the crank handle, the receptacle having a first portion in the transverse plane adapted to receive the body portion of the crank handle and a second portion with a slotted opening defined perpendicular to the transverse plane, the slotted opening having a sidewall being defined axially offset from the rotational axis of the crank handle and adapted to receive in close fitting relation the bent gripping portion of the crank handle, thereby facilitating insertion of the bent gripping portion of the crank handle in the second portion of the receptacle; and a hand grip mounted on the second end of the shaft, such that grasping the hand grip and rotating the shaft about its axis causes the crank handle to rotate, wherein the sidewall of the slotted opening is configured to bear upon the bent gripping portion of the crank handle when a crank handle is received in the receptacle of the member and the elongate shaft is rotated.
