Patent ID: 8484894

Claim:
A method of operating a door assembly including a first door and second door, comprising the steps of: pivoting the first door to the closed position; pivoting the second door about a second pivot axis from a closed position to an open position when the first door is in the closed position such that when the second door is in the a fully open position, an opening of the second door faces in a direction opposite the direction of an opening of the first door when the first door is in the a fully open position; pivoting the first door about a first pivot axis from a closed position to an open position such that the first door acts as an inlet; pivoting the first door to the closed position; pivoting the second pivot axis about the first pivot axis when pivoting the first door, the second door being of a smaller size than the first door and forming at least a portion of the first door; and pivoting the first door and the second door between each door's respective open and closed positions using a single actuator and a linkage assembly comprising a radial arm fixedly coupled to the actuator and a link pivotably coupling the radial arm to the second pivot axis.
