  • Publication number: 20050197057
    Abstract: An air curtain doorway for preventing cross-filtration of air at a doorway between a relatively warm area and a relatively cool area has duct work and an air mover. The duct work includes a supply air duct and a return air duct at opposite sides of the doorway joined by an intermediate air duct at the top of the doorway. The intermediate air duct houses the air mover, which creates an air stream circulated through the duct work that blows an air curtain from the supply air duct to the return air duct. The return air duct has an enlarged collector chamber upstream of an adjustable return air inlet aperture into which the downstream end of the air curtain is drawn. The supply air outlet aperture is at the base of a nozzle that has an upper portion that directs the air curtain toward the warm side and a lower portion that directs the air curtain toward the cold side of the doorway.

  • Publication number: 20050028946
    Abstract: An industrial sliding door has one or more panel assemblies, each panel assembly having a track panel secured to a header and a swinging panel hinged at the inner edge of the track panel to pivot in either direction about a vertical axis if the swinging panel is impacted by a vehicle such as a fork lift. Both panels can also pivot in at least one direction about a horizontal axis. A rail mounted stationary relative to the doorway at the lower edge of the door holds the lower edge of the door in proximity to the doorway and is disengagable if the door is hit from the opposite side, to permit the door panel assembly to swing about the horizontal axis away from the doorway. The swinging panel is held by a detent in the plane of the track panel in a normal position.
