REMOVABLE STRUCTURE FOR TURN AND TILT OR TILT LEAF OF WINDOW OR DOOR FOR MANUAL AND/OR MECHANICAL TILTING Russian patent published in 2016 - IPC E05D15/52 

FIELD: construction.

SUBSTANCE: removable structure (1) for a turn and tilt leaf of a window or a door with a lock module (4) located on a leaf (3) and a frame (2) comprising scissors (40) and lock elements. To remove the leaf (3), the scissors (40) by one end are fixed on the frame (2) as capable of rotation, and by the other end are fixed on the lock module (4) of the leaf (3) as capable of rotation and displacement, and lock elements located on the leaf (3) are movable relative to lock elements located on the frame (2) opposite to each other and may be engaged, and also with a basic part (5) fixed on the frame (2) of the window/door frame, where scissors (7) are located driven by means of a mechanical driving device (6), which comprise a connector (8) with lock elements of the lock module (4) arranged on the leaf (3). The connector (8) represents a connection element of a driving rod (9) and forms a connection between the mechanical driving device (6) and the lock module (4), thanks to which by means of the mechanical driving device (6) the lock module (4) may be put in the locking and unlocking positions, so that the basic part (5) has a body 10, comprising a mechanical driving device (6). The mechanical driving device (6) comprises a spindle (18), a spindle nut (19) moved on the spindle (18) in the longitudinal direction of the body (10), a grip pin (20), which moves on the body (10) and is connected with one end (17) of a unilateral flexible circuit (15) and a driving motor (21). Scissors (7) comprise a bracket (11). A straight splint (12) located on the bracket (11) longitudinally moves with the pin (13) located on the basic part (5) and is arranged so that it rotates along the axis of the pin (14) and is connected with the other end (16) of the unilaterally flexible circuit (15). The unilaterally flexible circuit (15) on its other end (16) is connected to the bracket (11) and has at its other end (16) a circuit stabilizer (29), which provides for impact of the torque at the circuit (15) around the axis (32) and continuously holds the circuit (15) between the bracket (11) and the basic part (5) in the unilaterally flexible position. The circuit stabilizer (29) interacts with two guides (30) located on the bracket (11) with appropriate pressure springs (31).

EFFECT: increased reliability of use.
