摘要： An automatic closure is disclosed which is adapted to block the flow of air through a door opening. The closure comprises a pliant curtain supported by its upper edge and by a portion of one side edge. The curtain includes a pocket which contains a bracing panel supported by the flanges of a pair of mutually perpendicular split sleeves. The sleeves are secured to a rotatable post, which normally assumes a preferred rotational position corresponding to the air-blocking position of the curtain in the door opening. The curtain, which also carries weights to facilitate its movement into and out of the latter position, is readily installed on, or removed from, its supporting structure.
