FIELD: construction.
SUBSTANCE: anti-breaking system of sliding frames for doors and windows comprising the immovable profile (1) of the guide frame and the movable profile (3) of the sliding frame. Wherein the profile (3) of the sliding frame has a cavity (5) made with the possibility to arrange the locking profile (4) therein. There is a pair of clamping parts (6) arranged inside said cavity (5) of the sliding frame profile (3) at the upper and the lower edges of the locking profile (4). Wherein each of the clamping parts (6) has side projections (8) ensuring its direction when entering into said cavity (5) of the sliding frame profile (3), the through opening (9) made with the possibility to enter a threaded fastening element for fastening the clamping part (6) relative to the sliding frame profile (3), and the recess (7) providing a drive element for moving the locking profile (4). Wherein the locking profile (4) has the slot (11) extending along the helical line in the middle of its height, made with the possibility to enter thereto the rod (10) adapted for linear movement in the slot (11) and providing the rotary movement of the locking profile (4). The immovable profile (1) of the guide frame is provided with a groove (2) adapted to grip the locking profile (4) so that the movable profile (3) of the sliding frame along entire its height is connected integrally with the immovable profile (1) of the guide frame inside it, when the system of sliding frames is brought in the locked state.
EFFECT: increase of reliability.
