A drill guide for a drill bit of a chucked hand-held drill is disclosed. The drill guide includes a mount, a coupler, a telescoping guard, and a guide foot. The mount is configured to couple to a non-rotating portion of the chucked hand-held drill. The coupler extends from the mount and forms a chuck access window aligned with the chuck when the mount is coupled to the non-rotating portion of the chucked hand-held drill thereby allowing a chuck key to interface with the chuck. The telescoping guard extends from the coupler and is configured to telescope into a retracted position from an extended position. The guide foot is coupled to the telescoping guard such that the drill guide enshrouds the drill bit when the telescoping guard is in the extended position, and the drill bit passes through the guide foot when the telescoping guard is in the retracted position.

The present disclosure provides system for sealing a refrigerated galley of an aircraft. The system includes a door, and a seal assembly positioned at a bottom surface of the door. The seal assembly includes (i) a housing coupled to the bottom surface of the door, (ii) a seal positioned at least partially in the housing, wherein the seal is moveable relative to the housing and the door, (iii) a biasing mechanism coupled to the housing and the seal and configured to hold the seal in a relaxed state by applying a biasing force to the seal in a direction away from a floor surface of the refrigerated galley, and (iv) an activation mechanism coupled to the housing. The activation mechanism is configured to transition the seal from the relaxed state to a compressed state in response to a rotation of the door from an open position to a closed position.

Systems and methods for sealing a refrigerated galley of an aircraft

A drill guide for a drill bit of a hand-held drill is disclosed. The drill guide includes a mount, a telescoping guard, and a guide foot. The mount is configured to couple to a non-rotating portion of the hand-held drill. The telescoping guard extends from the mount and is configured to telescope into a retracted position from an extended position. The guide foot is coupled to the telescoping guard opposite the mount such that the drill guide enshrouds the drill bit when the telescoping guard is in the extended position, and the drill bit passes through the guide foot as the telescoping guard telescopes into the retracted position from the extended position.

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.
