Abstract
A door assembly has a first door integrated with a second door. The first door has a first door cowl. The second door is pivotably mounted to the first door and has a second door cowl forming at least a portion of the first door cowl. The door assembly includes at least one actuator coupled to the first and second doors. Each one of the first and second doors is pivotable between open and closed positions and defines an opening when moved to the open position. The openings of the first and second doors face in opposite directions. The actuator is operative to pivotably move at least one of the first and second doors between the open and closed positions.
Claims16
A door assembly, comprising:
- a first door acting as an inlet and having a first door cowl being pivotable about a first pivot axis;
- a second door acting as an outlet and having a second door cowl being of a smaller size than the first door cowl and being contained within boundaries of the first door cowl and forming at least a portion of the first door cowl, the second door cowl being pivotable about a second pivot axis, the second pivot axis being pivotable about the first pivot axis;
- and
- at least one actuator coupled to the first and second doors;
- wherein:
- each one of the first and second doors is pivotable between open and closed positions and defining an opening when moved to the open position;
- the second door being pivotable into the open position when the first door is in the closed position;
- the openings of the first and second doors facing in opposite directions;
- the actuator being operative to pivotably move at least one of the first and second doors between the open and closed positions.
