Abstract:
1. A door lock assembly adapted to secure a door in a closed configuration within a doorframe, the door lock assembly comprising: a bolt guide; a bolt extending between a proximal end and a distal end, the bolt including a first portion adjacent the proximal end and a second portion adjacent the distal end, and the bolt including a spring metal core surrounded by an energy absorbing polymer; a bolt actuator adapted to move the bolt along the bolt guide between a locked position and an unlocked position, the second portion of the bolt extending beyond the bolt guide when the bolt is moved to the locked position; and a bolt receiver adapted to receive the second portion of the bolt when the bolt is moved to the locked position; wherein the bolt is adapted to deform within the bolt receiver and thereby absorb energy delivered to the door lock assembly by an intrusion load; and wherein the energy delivered to the door lock assembly by the intrusion load is predominantly absorbed by deformation of the bolt.
