Abstract
An overhead storage device having a lifting range. A constant torque spring is attached to a power pulley and is adapted to apply an approximately constant torque to the power pulley. A cable is partially wound around the power pulley and has an attachment mechanism at one end of the cable. A locking mechanism is adapted to permit the attachment mechanism and an attached load to be lowered and locked at any desired position within the range of the device. The approximately constant torque applied by the constant torque spring continuously causes the cable, unless restrained, to be further wound on the pulley.
