Abstract:
The present disclosure provides a system for sealing a compartment. The system includes a door with a seal positioned on a bottom surface of the door. The system also includes one or more hinges coupled to the door. The door rotates from a closed position to an open position via the one or more hinges. A height of the door with respect to a floor surface increases in response to a rotation of the door from the closed position to the open position due to a helical slope of both a first cam surface of the one or more hinges and a second cam surface of the one or more hinges. The seal transitions from a compressed state to a relaxed state in response to the rotation of the door from the closed position to the open position.
