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.

The present disclosure relates to an air tight door including a frame having three frame members disposed, respectively, at a first lateral side, a second lateral side, and an upper side of an opening; and a longitudinal member disposed at a lower side of the opening. The door is rotatably connected to the frame member disposed at the first lateral side of the opening so as to open and/or close the opening. A first sealing disposed at each of the three frame members closely contacts the door in a closed state; and a second sealing elevatably disposed at a lower end of the door descends from the lower end of the door to closely contact the longitudinal member in the closed state. A locking device fixes a position of the door in the closed state; and an actuating device is configured to unlock the locking device.

A sliding door system (105) includes a track assembly (120) and a door (125) slidably connected to the track. Seals (245, 250, 605, 610, 300, 500) disposed about the door limit sound and/or infectious materials from passing thereby. One or more of the seals (245, 250) are disposed between the door and the track assembly. One or more other seals (605, 610) are disposed between the door and a wall to seal around the trailing end of the door. The system may also include a door dock (130) with one or more seals (300, 500) to seal around the leading end of the door. The system can also include a drop seal assembly (700) that selectively seals off a gap between the bottom of the door and the floor.

A sealing assembly for a door of a vehicle includes a housing provided on the door, a sealing slider retractably mounted in the housing, a drawing-out device for urging the sealing slider away from the housing, an inserting device for urging the sealing slider into the housing, and a weather strip for air-tight sealing with the sealing slider when the door is closed, where the drawing-out device includes an operating lever rotatably installed on the housing to push an end portion of the sealing slider away from the housing and a support to rotate the operating lever in response to closing of the door, where the sealing slider is slidably movable between a first door and a second door.

A drop down seal is provided which has a channel-shaped external support profile configured to be fixed to a base of a panel of a door or window, a rod-shaped support element slidably housed in the channel-shaped external support profile and a movable element connected to the rod-shaped support element by a parallelogram articulation mechanism allowing the movable element to move in height between a raised rest position and a lowered working position. The movable element, when in the raised rest position, is also operationally and removably connected to the channel-shaped external support profile. The rod-shaped support element, at a proximal end thereof, forms, or is provided with, a laterally protruding control portion configured to be engaged by a trigger base fixed to an abutment surface.

A door sealing mechanism includes a solenoid for operating a cam mechanism to extend or retract a spring mechanism, causing a seal to engage/disengage with a floor/threshold, for allowing ease of opening/closing of the door while still providing sealing when the door is closed.
