ROTARY HANDLE-EQUIPPED SECURING SYSTEM APPLICABLE TO SLIDING DOOR AND WINDOW LEAVES

摘要

Novelty: a rotary handle-equipped securing system applicable for sliding door and window leaves is disclosed. Constitution: a handle-lever 4 or, alternatively, a spaniolet-type handle 12 connected to the lock’s body 3 via a square axle 5 and having a rotary portion 1 with integral Y-like pin 9, and a portion 2 provided with the securing tongue 6 which screws into threads and enters the aperture 7 of the frame for securing up the door or window leaves. Operation mode: the rotary portion 1 is secured by the square axle 5 via the securing axle 10, the handle 4 and the pin 11 so that -when the handle 4 is displaced from the idling 1 to the operational position 2- the portion 1 can rotate via the square axle 5 and the incorporated rotarily moving pin 9 can trace a complete constant-radius cycle urging the portion 2 with which said pin is constantly engaged to rectilinearly move up and down inside the groove 13 for securing the securing tongue.
