发明名称 Door opening system
摘要 A door opening system for permitting ingress and egress through a door utilizing a displaceable impact loading in one motion of a user. The door opening system includes a broad surface planar member which extends in a transverse direction across the door to be opened. The planar member has a mechanism for actuating a door latch mounted to a rear surface thereof. By displacing the planar member in a unitary direction, the actuating mechanism which interfaces with a latch lever displaces the latch lever and removes the lever from a catch member. Thus, the door is unlatched and continued motion or displacement by the body of the user against the planar member causes an opening of the door.
