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.

Systems and methods for providing a door seal system for top-hanging sliding doors. In some implementations, two angled mating surfaces are used, one angled surface on a fixed frame and one reversed angled surface on the slideable door panel. The slideable door panel slides directly parallel to the fixed door frame. A mating seal surface is created that is only in frictional contact for a small portion of the linear slide distance of the door panel. In some implementations, rather than placing two opposing angled seal surfaces, the sealing system has one angled surface on the fixed door frame. In such implementations, the sliding door panel is adjusted to be in a reverse angled orientation relative to the angled surface of the fixed door frame. Seal designs for the rear vertical edge of the slideable door panel are also provided herein.

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.

The invention relates to a drop-down seal for a building part comprising a housing (1), a sealing strip (2, 3) that can be raised and lowered in said housing (1), and a spring-loaded lowering mechanism (8), which causes automatic lowering of the sealing strip (2, 3) when the building part is closed. The lowering mechanism (8) is connected to a slide (4, 6), which protrudes beyond the housing (1) at one end and which activates the lowering mechanism (8) when the building part is closed. The slide (4, 5) applies a tension to the lowering mechanism (8). The drop-down seal according to the invention enables a one-sided triggering in tension, wherein the seal has a space-saving design.

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.

A door opening and closing device for a refrigerator includes a door coupled by means of a hinge unit to a main body defining a storage compartment therein, a gasket disposed between the door and the main body to provide a hermetic seal therebetween, and an opening and closing unit for opening and closing the door with respect to the main body, wherein the opening and closing unit includes a drive unit for generating a driving force, a gasket separation mechanism for pushing the main body using rotational force transmitted from the drive unit to separate the gasket from the main body or the door, and a door rotating mechanism for rotating the door using the rotational force transmitted from the drive unit.
