ABSTRACT:
A pet door hinge adapted to accommodate potentially damaging forces. The hinge mechanism includes a shaft that is received by a shock-absorbing bearing. The bearing is received by a sleeve. The bearing rotates within the sleeve to allow pivoting of the flap. In the event of potentially damaging forces, a resilient and deformable material forming the core of the bearing gives to prevent damage to or destruction of the hinge mechanism or the pet door.
