   Gemäss Fig. 2 ist ein Doppelzylinderschloss dargestellt, dessen Kupplung aus zwei zwischen den Zylinderkernen--2, 3--auf einen Rohrniet--18--verschieblich angeordnete, durch eine   Feder--19--   im Abstand voneinander gehaltene Scheiben-20, 21-besteht. 



   Bei eingeführtem   Normalschlüssel--15--in   das Doppelzylinderschloss wird die dem Normalschlüssel -   -15-- zugekehrte Kupplungsscheibe --21-- maximal   2/3 mit dem   Mitnehmersteg --22-- in   die Nut --23--derSperrnase--12--eingeschoben. 



   Um zu verhindern, dass auch die zweite   Kupplungsscheibe--20--in   die Sperrnase--12--eingreift, sind die beiden Kupplungsscheiben--20, 21--nach aussen wirkend durch eine Feder--18--belastet. Die   Feder--18--kann   als Schraubenfeder oder Federscheibe   od. dgl.   ausgebildet sein.

    --15-- verdreht--16--   an der Aussenkante der Kupplungsscheibe--20--, die Zuhaltungsstifte auf Teilung gebracht, wodurch der   Zyliderkern--3--gemeinsam   mit der Kupplungsscheibe--20--gedreht werden kann. 
 EMI2.2 
    --16-- wirdNotschlüssels--16--wird   nun die Sperrnase--12--mitgenommen und das Schloss kann geöffnet werden. 



   Der Ablauf des öffnens wird noch erleichtert, wenn der verdreht angesteckte   Normalschlüssel-15-bis   zur Nullstellung mitgedreht und dann durch den Notschlüssel --16-- über die Kupplung so weit aus dem Schloss geschoben wird, dass auf der Notschlüsselseite eine normale Schlüsselbetätigung erreicht wird.

   According to Fig. 2, a double cylinder lock is shown, the coupling of two between the cylinder cores - 2, 3 - on a tubular rivet - 18 - arranged displaceably, held at a distance from one another by a spring - 19 - 21-consists.



   When the standard key - 15 - is inserted into the double cylinder lock, the clutch disc --21-- facing the standard key - -15-- is inserted a maximum of 2/3 with the driving bar --22-- into the groove --23 - of the locking lug-- 12 - inserted.



   In order to prevent the second clutch disc - 20 - from engaging in the locking lug - 12 -, the two clutch discs - 20, 21 - are loaded by a spring - 18 - acting outwards. The spring - 18 - can be designed as a helical spring or a spring washer or the like.
 EMI2.1
    --15-- twisted - 16-- on the outer edge of the clutch disc - 20--, the tumbler pins are split so that the cylinder core - 3 - can be rotated together with the clutch disc - 20 -.
 EMI2.2
    --16-- If an emergency key - 16 - is used, the locking lug - 12 - is now taken along and the lock can be opened.



   The opening process is made even easier if the twisted normal key -15-is turned to the zero position and then pushed out of the lock by the emergency key -16- over the coupling so that normal key operation is achieved on the emergency key side .
