Schließeinrichtung für Riegelfallenschlösser, insbesondere für Hotelgastzimmertüren

摘要

An inside turn knob is equipped with an axially movable coupling member spring pressed to position coupling the knob to a deadbolt operating cam. A guest key inserted into an outside tumbler cylinder will press the coupling member to release position so that the key when rotating a latchbolt operating cam and the turn knob will not rotate the deadbolt cam. A manager's key is relatively short and will not depress the coupling member, and therefore can rotate the deadbolt cam along with the latchbolt cam.
