FIELD: mechanical engineering.
SUBSTANCE: sliding mechanism for opening and closing, as well as for turning and/or tilting and blocking the closed state of the locking mechanism, at least by partially closing the opening, pivoting and/or tilting window or door. The technical result is achieved by the fact that the retractable mechanism for the tilt-and-turn leaf of a window or door, containing a locking mechanism on the leaf and a base part fixed to the frame, on which a force transmission means actuated by a mechanical drive device is installed, having a connecting element with the leaf, so that the connecting element is a connecting element of the drive rod, and the connecting element of the drive rod is located at the free end of the force transmission means with the possibility of connecting with the element of the drive rod located on the locking mechanism and the locking pin moving on it, moreover, with the help of a mechanical drive device by moving in the direction movement of the drive rod element with the locking pin located on it, the leaf takes the position of locking or unlocking, while the retractable mechanism contains a device for aligning the base part located on the frame with a force transmission means and a locking mechanism fixed to the leaf, which consists of a locking mechanism fixed in the body of the base part of the element and the trunnion fixed by the locking mechanism, wherein the engaging element and the trunnion form a dimensionally stable connection and the trunnion provides a constantly maintained distance of the value X to the corresponding predetermined positions of locking, or turning, or tilting the leaf to the locking trunnion, and the trunnion, when installed on the sash by a rigid connection, takes a constant rotary position, and the engaging element is rigidly connected by geometrical and/or forceful closure with the base part on the frame, and together they form an alignment device.
EFFECT: simple, fast, reliable and accurate mounting.
