DEVICE TO OPEN PARACHUTE Russian patent published in 1994 - IPC

FIELD: aviation technology. SUBSTANCE: device has flexible pin 1, aneroid mechanism 2 and clock mechanism 3, located in device body 5 blocking levers 4, lock 6, fixed on body 5 lower side pulling mechanism 7. Pulling mechanism 7 has guiding pipe 8, shock absorber 9, heavy-duty springs 10, piston 11 with fixed rope 12. Flexible polymeric pipe 13 with armed cover 14 is fixed on guiding pipe 8. Adjusting collar 16 is mounted on tail 15 of armed cover 14 free end. polymeric pipe 13 is made of fluoroplastic with armed cover 14, made of metal wire and polymeric threads flexible pin 1 is pulled out, it starts clock mechanism 3, driven by springs. Motion from clock mechanism 3 through system of gears is passed to blocking levers 4, that open lock 5 of pulling mechanism 6. Flexible pipe in the form of polymeric pipe 13 with armed cover 14 is fixed to output coupling of guiding pipe 8. Flexible pipe 13 with armed cover 14 is by other end 15 connected through adjusting color 16 with joints of parachute pack. Flexible pipe provides protection of rope 12 from external actions without limiting its freedom. EFFECT: device is used in aviation as parachute lock. 4 cl, 2 dwg
