FIELD: window making.
SUBSTANCE: invention relates to the structure of a mechanism for opening pivoting-folding shutters of windows or doors. The retractable mechanism for pivoting-folding shutters of windows or doors contains a regulating traction mechanism, which is moved by means of a drive along a fold of a shutter to various fixed positions. Retractable bracket (19) is located on the opening side of the shutter opposite the vertical rotary axis, which, in the position of the pivot opening, is connected by means of connecting element (18) to retractable guide (1) located on the frame along the plane of frame fold (RF). Retractable guide (1), open on both sides, contains guide jumper (4) located in the direction of opening of the shutter, connected by a geometric closure to bar (8) of support plate (2), and it is made with the possibility of moving along the plane of frame fold (RF) relatively to support plate (2). Opposite movable guide jumper (4), there is fixed guide jumper (3), which includes locking element (6) for connecting element (18).
EFFECT: invention is based on the task of creating a retractable structure that provides simpler and fault-tolerant operation.
