Abstract
A strip-type door having a plurality of individual strips arranged in overlapped relationship one to another comprises a series of swingable supports on which the individual strips are vertically suspended when the latter take a vertical position. A mounting element connected to a lintel over the door opening has a mounting portion, a supporting bar and an arcuate wall defining an arcuate channel. Each of the supports is formed with a curved portion insertable into the channel in the mounting element to form with this wall a hinge about which the supports carrying the individual strips can swing relative to the mounting element between a plurality of positions. The curved end portion may be inserted into said channel in only one of these positions so that the inadvertent falling or removal of the supports out of the channel when the strips are in their working swingable positions is prevented.
