A system for mounting a secondary panel within a window frame of an existing window. The system includes a rigid panel, an elongated deformable bulb, and an elongated carrier. The bulb has a resilient portion, a base section, an extension extending from the base section, and a crosspiece coupled to a distal end of the extension. The crosspiece includes a pair of shoulders at opposite ends of the crosspiece. Each shoulder protrudes laterally beyond the extension. The elongated carrier has a receiving slot opposite a panel gap configured to receive an edge of the panel. The receiving slot has a neck laterally narrower than an interior cavity of the receiving slot. The receiving slot is configured to securely receive the crosspiece of the bulb and to confine the shoulders of the crosspiece.

A roll-up door assembly including a plurality of door panels; a pneumatic seal apparatus having an elastic membrane of an elongated tube disposed around a perimeter of the trailer door so as to be adjacent to the plurality of door panels, wherein pressurized air is injected into the pneumatic seal apparatus to expand the elastic membrane and to apply an outward force against multiple sides of the plurality of door panels, wherein applying the outward force against the plurality of door panels on multiple sides keeps the plurality of door panels as a single unit such that substantially less air flows through the plurality of door panels than prior to the application of the outward force to seal the trailer door.

A sealing system for doors and windows includes a reservoir device, a sealing tube configured to expand and to contract, and a transfer valve configured to couple the reservoir device to a first end of the sealing tube. Responsive to either of a door or window closing, a medium may be transferred from the reservoir device via the transfer valve to the sealing tube. Responsive to receiving the medium, the sealing tube may expand to substantially seal a gap between an edge of either of the door or the window and a surface in proximity to the edge. Responsive to either of the door or window opening, the medium may be discharged from the sealing tube via the transfer valve. The sealing tube may contract in response to discharging the medium.

An inflatable, window-covering system is described. The inflatable, window-covering system may include an inflatable cushion and a drive assembly, the drive assembly including a power source; one or more sensors, where the one or more sensors may be configured to detect a triggering event; and an air pump configured to inflate the inflatable cushion based, at least in part, on the detected triggering event. In some cases, the triggering event may include any of sensing a predetermined temperature, sensing a predetermined level of light intensity, sensing a predetermined time, or receiving an instruction, or any combination thereof.

A method for reducing air leakage from a refrigerated container includes positioning at least one inflatable device about a rear end of the refrigerated container; coupling the at least one inflatable device to one end of an elongated duct located within an interior space of the refrigerated container; coupling a second end of the elongated duct to an outlet port of the evaporator fan; circulating, via the evaporator fan, air through the interior space; and extracting the circulated air through the elongated duct and into the at least one inflatable device.

An inflatable barrier (10) including a wall member (12) which includes at least one inflatable element, and at least one frame member (22), the frame member (22) including a guide formation (16), the at least one guide formation (16) including a channel in which at least a part of a corresponding guide member (24), which is carried by the wall member (12), is receivable, wherein in use, at least a part of the guide member (24) is able to travel along the channel of the guide formation (16), to at least assist in erecting the wall member (16) from an inactive position to an in use position.

A pedestrian door system includes a door frame comprising a frame strike side, a frame hinge side, and a frame sealing surface that extends up each of the frame strike and frame hinge sides. A threshold extends between the frame strike and frame hinge sides and includes a base secured to a floor surface and a threshold sealing surface. A door panel includes a panel bottom side, a panel strike side, a panel hinge side, and a continuous gasket extending continuously along the panel bottom side and up each of the panel strike and panel hinge sides. A door hinge couples the panel hinge side to the frame hinge side and facilitates hinged movement of the door panel between an open position and a closed position in which the gasket seals against the frame sealing surface and the threshold sealing surface in a liquid-tight manner.

A system for mounting a secondary panel within a window frame of an existing window. The system includes a rigid panel, an elongated deformable bulb, and an elongated carrier. The bulb has a resilient, rounded portion, a base section, an extension extending from the base section, and a crosspiece coupled to a distal end of the extension. The crosspiece includes a pair of shoulders at opposite ends of the crosspiece. Each shoulder extends laterally away from a centerline of the bulb and protrudes laterally beyond the extension. The elongated carrier has a receiving slot opposite a panel gap configured to receive an edge of the panel. The receiving slot has a neck laterally narrower than an interior cavity of the receiving slot. The receiving slot is configured to securely receive the crosspiece of the bulb and to confine the shoulders of the crosspiece.

A sectional door comprising a plurality of panels which can be stacked on top of each other in a stacked state, and next to each other in a stored state; a drive system with a cable or chain for moving the bottom panel in the height direction; upright rails for guiding the panels in the stacked state; means for guiding the panels in the stored state comprising a worm wheel with helical groove for guiding the panels in the storage room; wherein the drive system further comprises a lifting mechanism for removing the upper panel from the stack, and for transferring it to the storage zone.
