    -m'belSichentng   für Rechenmaschinen. 



   Bei den bekannten Kurbelsicherungen für Rechenmaschinen ist der unter der Wirkung einer (oder mehrerer) Feder stehende Federbolzen des Griffes so lang gewählt, dass er beim Vorbeischlagen der Handkurbel am Kurbelbock mit seinem hinteren Ende aus der dafür vorgesehenen Aussparung des Griffes herausgedrängt wird. Befindet sich ein Finger des Benutzers der Rechenmaschine gerade an dieser Stelle des Griffes, so wird das Heraustreten des Federbolzens gehindert und das vordere, in die Sicherungrast eintretende Ende des Federbolzens schlägt bei einer Kurbeldrehung gegen den Kurbelbock der Maschine.

   Um das Auftreten dieses, ein   Uberschleudern   der drehbaren Einstellteile herbeiführenden Schlages zu vermeiden, ist nach der Neuerung der Kurbelgriff so lang gewählt, dass er in der nicht zurückgezogenen Stellung den Federbolzen auch in seiner am weitesten zurückgedrängten Lage deckt. 



   In der Zeichnung ist eine als Beispiel dienende Ausführungsform der Neuerung in Seitenansicht und teilweise geschnitten dargestellt. 



   Für den im Innern des Griffes a der Kurbel   l) eingesetzten   Federbolzen   c,   der in eine Rast am   Kurbelbock d   der Rechenmaschine eingreifen kann. ist im Griff a eine Eindrehung e vorgesehen, in der 
 EMI1.1

    -furniture security for calculating machines.



   In the known crank locks for calculating machines, the spring bolt of the handle, which is under the action of one (or more) springs, is chosen to be so long that when the hand crank hits the crank bracket, its rear end is forced out of the recess in the handle provided for this purpose. If a finger of the user of the calculating machine is at this point on the handle, the spring bolt is prevented from stepping out and the front end of the spring bolt entering the safety catch strikes against the crank bracket of the machine when the crank is turned.

   In order to avoid the occurrence of this shock causing the rotatable adjustment parts to be thrown over, the crank handle is chosen so long that it covers the spring bolt in its most pushed-back position in the non-retracted position.



   In the drawing, an exemplary embodiment of the innovation is shown in side view and partially cut.



   For the spring bolt c inserted inside the handle a of the crank l), which can engage in a latch on the crank bracket d of the calculating machine. a recess e is provided in the handle a, in which
 EMI1.1
 can.
