HIGHER SECURITY LOCKING DEVICE Russian patent published in 1997 - IPC

FIELD: shackle-lock production engineering. SUBSTANCE: device has lock 1 and locking rods 11 and 12 connected with lock cross-bar 3 by rectilinear kinematic pairs, each of them is made like resilient connection of finger-pin 5 and elongated groove 14, which direction makes acute angle with cross-bar 3 motion direction. Device is furnished by one at least additional lock 2 arranged in parallel with respect to first lock, but cross-bar 4 of second lock interacts with cross-bar 3 of first lock 1 and second locking rod 12 just like lock 1 does. Both locks cross-bars are connected between by dynamic link composed by rectilinear kinematic pairs, and one of them is analogous with mentioned above, but second differs from first one by groove stepped geometry. Higher reliability and better secrecy are achieved by means of two or more standard locks using by the way of interaction between them while mounting on guarding object. EFFECT: higher reliability, better secrecy of lock. 2 cl, 10 dwg
