Device for pivoting a frame in an opening (bay)

摘要

Device for pivoting a frame in an opening, characterised in that it is formed by two arms (3) constituting the side branches of a stirrup-shaped piece, the central part (4) of which can pivot freely about a longitudinal axis (YY1) parallel to the usual axis (XX1) for pivoting the frame. The free ends of the arms (3) are guided in a groove made on the internal face of the uprights of the frame (1), an adjustable stop being arranged in at least one of the grooves in order to limit the pivoting of the arms in the direction of opening of the frame. <IMAGE>
