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 thedoor 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 transitionsfrom a compressed state to a relaxed state in response to the rotation of the door from the closed position to the open position.

Description

technical field [0001] The present disclosure relates generally to systems for sealing compartments and, more particularly, to lifting a seal placed on the bottom surface of a door when the door is opened to prevent the seal from dragging along the floor surface when the door is opened. system. Background technique [0002] The galley trolley compartment of an aircraft is often refrigerated to keep the contents cold. Traditional kitchen doors in such refrigerated areas use seals to keep the compartment cold. To maximize the interior volume of the compartment, the door extends to the floor, and a seal is placed along the bottom surface of the door and in contact with the floor. Existing seals on conventional kitchen doors may be more accurately described as close-outs. Such seals are typically "whisker brush" devices that allow air to flow through the whiskers, and otherwise do not seal completely against the floor since they cannot bend and conform to the floor. Further,...
