ABSTRACT:
A closure structure especially for openings in a building, in which a flexible closure member (e.g. a door) is laterally guided in substantially vertical guides and is prevented from accidentally slipping out of the vertical guides by means of latching members, e.g. steel balls, which during the downward movement of the closure member are released through a discharge opening of a magazine into and through a passage in the closure member and into the respective adjacent guide. In response to the upward movement of the closure member, the latching members are returned to the magazine and stored therein. The upward movement of the closure member is brought about by winding the latter up upon a reel, and the downward movement of the closure member is brought about by winding the closure member off the reel.
