초록 ▼

A method and apparatus for rapidly and reliably sealing off a selected opening from an adjacent path of smoke, noxious fumes or contaminated air which comprises a reel of reinforced transparent, temperature, chemical or radiation resistant material having flexible magnetic edge strips on each side thereof mounted and centered above said opening, and causing the reel to drop in vertical fall adjacent to the opening and simultaneously causing the flexible magnetized strips to become rapidly and magnetically attached to ferromagnetic side rails or ferromagnetic door frame used for fire doors and to expand under pressure while maintaining an air tight seal of the opening. This apparatus is elegantly simple and reliable in both its construction and operation and has an extremely high price/performance figure of merit.

An apparatus for rapidly and reliably sealing off an opening defined at a lower limit by a floor in response to smoke, noxious fumes, or contaminated air, comprising: a curtain of temperature, chemical or radiation resistant flexible material reinforced to limit ripping of the curtain if penetrated or punctured; a flexible magnetic strip means attached to and extending along each of the left and right edges of the curtain; an expansion means attached to the curtain to allow expanding movement of the curtain in response to differential pressure after deployed; a fire resistive container located adjacent to an upper limit of the opening; a reel means initially positioned within the container and upon which the curtain is wound in preparation for deployment, the reel means being movable downward and upward across the opening, the reel means being rotated to unroll the curtain from the reel means in a position adjacent to the opening as the reel means moves downward, and rotated to subsequently rewind the curtain onto the real means as the reel means moves upward to allow passage through the opening; a powered, automatic drive means connected to the reel means to brake the downward movement of the reel means and rotate the reel in one rotational direction as the reel moves downward to unroll the curtain and to move the reel means upward and rotate the reel in an opposite rotational direction as the reel means moves upward to rewind the curtain onto the reel means; a deployment control means which stops the drive means to limit the downward movement of the reel means and the unrolling of the curtain when the curtain is at a position adjacent to the floor; a rewind control means which stops the drive means to limit the upward movement of the reel means and the rewinding of the curtain onto the reel means; a bottom seal means which resists air leakage between the curtain and the floor when the curtain is positioned adjacent to the floor; a ferrous metal frame means attached to the wall directly adjacent to each of the left and right sides of the opening, the curtain being sized such that as the curtain unrolls from the reel means as the reel means moves downward, the flexible magnetic strip means attached to each edge of the curtain is magnetically attached to a corresponding one of the frame means; and a ferrous metal seal means located at the junction of a lower end of each of the frame means and against the floor such that when the curtain is positioned adjacent to the floor the flexible magnetic strip means attached to each edge of the curtain is magnetically attached to a corresponding one of the seal means to resist air leakage between the curtain and the seal means.
