Abstract (en)

A cog wheel (9) of the gear, preferably the driving cog wheel directly or by means of pins fitting into the slide rod cogging, caries a carrier (18) on its flat side. A ring (19) is mounted on the same axis of the cog wheel and is held by the carrier. The ring has a carrier surface (22) in whose rotary circle a contact point of the change lever (13) is swiveled. An annular surface next to the carrier surface ejects the lever from the contact position.

Abstract (de)

Ein Mehrriegelverschluss mit Schließzylinderbetätigung und Getriebe weist zur Fallenbetätigung einen Wechselhebel (13) auf. Das abtreibende Zahnrad (9) des Getriebes wirkt über einen Mitnehmer (18) auf einen koaxialen drehbar gelagerten Ring (19), der gegenüber dem Mitnehmer einen Freiwinkel aufweist. Der Ring (19) trägt seinerseits eine Mitnehmerfläche (22), die auf den etwa tangential am Ring (19) unter Federvorspannung anliegenden Wechselhebel (13) bei einer Weiterdrehung nach dem Aufsperrvorgang einwirken. Durch Anheben des Wechselhebels (13) schwenkt ein Winkelhebel (14) um und zieht die Falle (12) über eine Stift (17)-Schlitzverbindung (15) ein. Es führt der Ring (19) eine geringere Winkelbewegung aus als das Zahnrad (9), sodass es nicht bei jeder Umdrehung des Zahnrades (9), sondern nur einmal im Anschluss an das Aufsperren zu einem Fallenrückzug über den Wechselhebel (13) kommt. Die am Wechselhebel (13) angreifende Feder (25) kann gleichzeitig als Fallenfeder ausgebildet sein. <IMAGE>
