Abstract

1. An emergency key device on a double-cylinder lock (1) comprising, in the case where a normal key (2) is inserted at one end, a locking member (4), which is rotatable from the other end by means of an emergency key (3), and further comprising a blocking coupling (11), which is displaceable in the locking member boss (5) for the purpose of alternately engaging the locking member (4) in, and disengaging it from, the two locking cylinder rotors (15, 16) arranged at the two ends of the locking member (4), the blocking coupling (11) having a groove (30; 31) at each of the end faces, and the tip of the key engaging in a shape-locking manner in these grooves (30; 31) ; characterized in that the boss (5) of the locking member (4) is provided with a planar serration (10) at at least one of the two end faces (8, 9) and in the zone opposite the locking cylinder rotors (15, 16), and in that a cam (29) is arranged at the forward end of the ward (27) of the emergency key, which cam extends beyond the outer limit of a normal key (2) and is so formed that when the emergency key (3) is fully inserted, the cam engages in one of the recesses in the planar serration (10) on the boss (5) of the locking member.
