Abstract
A blocking system for doors, windows and the like, particularly of the armored type, to have antitheft, antibreaking, fluid-tight and soundproof features, comprising a frame (11), a wing (12) and two pairs of mechanically interconnected blocking members (13,13'-14,14') which are arranged in housing slots (15,15'-16,16') provided along the opposite perimetrical flat inner edges of the frame (11) and sliding into facing slots (17,17'-18,18') of the wing (12) by the tension action of springs (34,34') to close the door, the backwards motion of these blocking members being carried out by the pushing action of a pin (38) which is manually operated through a central control device (20), when the door is to be opened. The outwards and backwards motions of the blocking members are synchronous and the outwards motion of same from the housing slots of the frame into facing slots of the wing is automatically provided by means of the tension of springs (34,34').
