Abstract

A sliding door closure system is provided including close and energy harvesting to recover kinetic energy from the motion of the door. According to some embodiments, the relative motion between a sliding door and sliding door track may be configured to drive a generator. The generator may be driven by a driving a wheel rotationally connected to the generator. Examples include driving the generator by a friction wheel, by a chain and sprocket, or by a gear and rack. The generator may recover kinetic energy from the motion of the door during the deceleration of the soft close function. Energy recovered from the door may be stored and used to assist the motion of the door or to operate sensors to monitor the operation of the door closure system. The door closure system may transmit data and preserve a record of use.
