Claim 0:
1. A door handle and locking system, including:
a base;
a first latching mechanism, the first latching mechanism being movable from a latched position to an unlatched position;
a handle connected to the base, the handle being movable from a first position in which the first latching mechanism is in the latched position to a second position in which the first latching mechanism is in the unlatched position;
a safety latch mechanism movable from a first position to a second position, the safety latch mechanism having a body having a first end, a second end, a first post extending from the body, and a second post extending from the body, the first and second posts connecting the safety latch mechanism to the base such that the safety latch mechanism is rotatable about the first and second posts from the first position to the second position;
a first biasing member for biasing the safety latch mechanism in the first position when the handle is in the first position, the first biasing member having a biasing force;
the first latching mechanism having a first cam mechanism, an actuator mechanism, a second cam mechanism, and a rotary mechanism;
the first cam mechanism having a shaft having a projection extending therefrom;
the actuator mechanism having a first end having a first projection extending therefrom, a second end having a second projection extending therefrom, and a third projection, the actuator mechanism being movable from a first position in which the first latching mechanism is in the latched position to a second position in which the first latching mechanism is in the unlatched position;
the second cam mechanism having a first arm, a second arm, a first opening, a second opening, and a second biasing member having a projection extending into the first opening of the second cam mechanism;
a third biasing member for biasing the second biasing member in a first position when the handle is in the first positon;
the rotary mechanism having a latch actuation mechanism, an actuator arm having a first projection extending through the second opening in the second cam mechanism, and a second projection that engages the latch actuation mechanism;
wherein moving the handle from the first position to the second position rotates the first cam mechanism so as to move the projection of the first cam mechanism into contact with the first projection of the actuator mechanism, thereby moving the actuator mechanism from the first position to the second position so as to engage the second projection of the actuator mechanism with the first arm of the second cam mechanism, thereby rotating the second cam mechanism such that the second cam mechanism bears against the first projection of the actuator arm to rotate the actuator arm such that the second projection of the actuator arm engages the latch actuation mechanism to move the first latching mechanism from the latched position to the unlatched position; and
wherein the safety latch mechanism remains in the first position upon movement of the handle from the first position to the second position.
