A seal for a sill-free door for sealing a gap between a door leaf and a floor has a carrier rail (2) and a sealing profile 13) retained on the carrier rail (2). The sealing profile (3) has a substantially u-shaped cross section with two limbs (30) and a sealing crosspiece (32), which connects the two limbs (30) to one another and is intended for bearing with sealing action on the floor. There is a cavity (37) present, said cavity being defined by an underside (23) of the carrier rail (2), by the limbs (30) and by the sealing crosspiece (32), wherein the sealing profile (3), on each limb (30), has at least one strip (34) which is arranged on an inner side of the limb (30), projects into the cavity and is intended for improving the sound insulation. At least two strips (34) have a thickness which is greater than the thickness of the adjacent region of the limb (30). Said seal has optimized sound insulation.

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.

The sliding door system includes a sliding door, displaceable along a running rail relative to a stationary activation member up to a closing position; which includes a door leaf equipped with an activatable sealing device including an extractable sealing strip and actuating element equipped with a transmission device including a transmission element; and includes at least two carriages, including a carriage body and running elements connected to the door leaf, and are held in the running rail displaceable in parallel to the longitudinal axis of the running rail; wherein the activation member and transmission device are arranged so that, when the sliding door enters the closing position, a force can be transmitted from the activation member via the transmission element to the actuating element in order to drive out the sealing strip. A stationary buffer device stops the sliding door in the closing position and includes the activation member.

A pet door apparatus (10) discloses a pet door frame (12), an opening (34), and closure flap (36) which is rotatable for at least partly closing the opening or extending away from the opening. A magnet (102) and magnetically attractable element are respectively on one or the other of the flap and frame, and an actuator can move the magnet or magnetically attractable element to change the distance, and magnetic attraction force, between them. A blocking member (176) attached to a side part (28) of the frame is movable under gravitational force and due to engaging cam surfaces (196, 198), from an extended, raised position for partially closing a gap (160) between the flap and frame, to a retracted, lowered position, and back to the raised, extended position by magnetic attraction between a magnet (164) on the flap and another magnet (190) on the frame.

Systems and methods for providing a drop seal assembly which is concealed within an opening in the bottom of a sliding door panel of a top-hanging sliding door. The drop seal assembly may include bottom guide which defines a downward facing elongated slot or track which receives a sill guide therein. The drop seal assembly also includes a drop down acoustic seal which automatically drops down to contact the floor surface below the door panel when the door panel is moved from an open position into a closed position. The distance that the seal drops down upon closing of the door panel may be selectively adjustable to accommodate variances in the air gap between the door bottom and the floor surface due to particular installation conditions. A concealed magnetic bottom seal activator may be used to provide self-adjusting activation of the door bottom seal assembly using two opposing magnets.

An automatic door seal is provided for sealing the gap between the lower edge of a door and a threshold. The seal is magnetically actuated so as to move downward into sealing engagement with the threshold when the door is closed and raises out of engagement when the door is opened. A transmission assembly converts horizontal movement from the magnetic force into vertical movement for the seal. Springs provide a reset force when the magnetic force is eliminated so as to retract the seal strip whenever the door is moved from the closed position.

The system includes a gear mounted for rotation relative to the fenestration member. A mechanical linkage connects the latch control member and the gear such that the gear is rotated from a first position, where the latch is disengaged, to a second position as the latch is moved to engage the fenestration member frame. A rack in engagement with the gear is mounted to a first bar for linear movement in a given direction as the gear is rotated. A first triangular member moves with the rack. A second triangular member attached to a second bar cooperates with the first triangular member to move the second bar in a direction substantially perpendicular to the direction of rack movement. A gasket moves with the second bar to a position abutting the adjacent surface to automatically seal the member to the adjacent surface as the member is latched.
