Trigger mechanism for hand firearms

Abstract

The invention concerns a trigger mechanism for hand firearms, in particular pistols, with a striking lever ( 2 ) for the actuation of a firing pin ( 6 ), a pre-tensioning spring ( 13 ) associated with the striking lever ( 2 ), a trigger spring ( 14 ), associated with the striking lever ( 2 ), a striking lever ( 5 ) for control of the pre-tensioning spring ( 13 ), and a trigger rod ( 8 ) which is connected with a trigger ( 9 ) at its front end and cooperates with the striking lever ( 2 ) and the control lever ( 5 ) at its rear end. A particularly compact design is thus attainable in that the pre-tensioning spring ( 13 ) and the trigger spring ( 14 ) are placed inside the striking lever ( 2 ).

1 . Trigger mechanism for hand firearms, in particular pistols, with a striking lever for the actuation of a firing pin, a pre-tensioning spring associated with the striking lever, a trigger spring associated with the striking lever, a control lever for control of the pre-tensioning spring, and a trigger rod which is connected with a trigger at its front end and which cooperates with the striking lever and the control lever, wherein the pre-tensioning spring and the trigger spring are placed inside the striking lever. 
   
   
       2 . Trigger mechanism according to  claim 1 , wherein the trigger spring is located within the pre-tensioning spring. 
   
   
       3 . Trigger mechanism according to  claim 1 , wherein the pre-tensioning spring is supported on a pre-tensioning spring guide located inside the striking lever. 
   
   
       4 . Trigger mechanism according to  claim 1 , wherein the pre-tensioning spring is supported on the pre-tensioning spring guide via a spacer sleeve. 
   
   
       5 . Trigger mechanism according to  claim 1 , wherein the trigger spring is supported on a trigger spring guide located inside the striking lever. 
   
   
       6 . Trigger mechanism according to  claim 5 , wherein the trigger spring guide is supported on a striking lever pin. 
   
   
       7 . Trigger mechanism according to  claim 3 , wherein the pre-tensioning spring guide is guided so it can be displaced and rotated inside the striking lever, and contains a latching cam for engagement in a latching recess on a latching slot in the striking lever. 
   
   
       8 . Trigger mechanism according to  claim 7 , wherein the control lever comprises a slot for engagement with the latching cam on the pre-tensioning spring guide. 
   
   
       9 . Trigger mechanism according to  claim 1 , wherein the control lever comprises a control surface for the actuation of a firing pin safety for the release or blocking of the firing pin. 
   
   
       10 . Trigger mechanism according to  claim 1 , wherein the trigger rod is associated with an interrupter lever for controlling the engagement of the trigger rod with the striking lever. 
   
   
       11 . Trigger mechanism according to  claim 7 , wherein a stop for the actuation of the latching cam on the pre-tensioning spring guide is associated with the striking lever. 
   
   
       12 . Trigger mechanism according to  claim 1 , wherein the trigger rod is pre-tensioned by a trigger rod spring.
