LOCK SYSTEM WITH MULTIPLE BOLTS WITH SECURITY DEVICE FOR DOORS

摘要

The safety system for a multiple door lock, with a central lock (1), has lower (2) and upper (3) rails with vertical movements bonded together with the bolt plate (5) and the holder (8) with its lateral strap (9) with a lower retainer (13) together with an upper retainer (14) and a swing lever (15), so that the lower rail has a weakened swing pin (10) sliding in an angled guide path (16) in the bolt plate. The upper rail has a further angled guide path (17) for a second weakened swing pin (11) assembled at the bolt plate. The two pins have a fracture strength which is lower than the lateral strap of the holder to act as a b lock for the bolt plate.
