Patent ID: 7815232

Claim:
A door closure assist assembly for assisting in the closing of a door with respect to a doorframe, the assembly comprising: an extender portion attached to one of the door and the doorframe, the extender portion comprising a shape memory material; a releasable fastener comprising a magnet attached to the extender portion and a ferrous material attached to the other one of the door and the doorframe; an activation device in operative communication with the shape memory material; and a controller in operative communication with the activation device, wherein, when the door is moved toward a closed position, an energy field will be created when the magnet is proximate to the ferrous material at a first distance, the energy field will be detected, making the controller activate the activation device, the activation device will send an activation signal to the extender portion, the shape memory material will be operated to change the fundamental property of the shape memory material when exposed to the activation signal so that the extender portion is caused to linearly expand to a first position, attaching the magnet to the ferrous material, when the magnet is attached to the ferrous material at a second distance, the activation signal will be deactivate, making the shape memory material reverse the change in fundamental property and return the extender portion to its original position, providing a final closing action to the door against the doorframe.
