The present invention relates to a torsion spring that has a proximal leg with a proximal segment and a distal segment, a distal leg with a proximal segment and a distal segment, and a coil between the proximal and distal legs. The torsion spring is preferably used adjacent to a door hinge to bias the door in an open position. The proximal segment of the proximal leg and the distal segment of the distal leg are preferably curved so that they may be hammered into the door and door frame in order to keep the torsion spring in place.
