Locking device for a pistol

Abstract

The invention concerns a blocking device for a pistol with a trigger, a trigger mechanism and a firing pin, hammer or the like operated by these. The invention is characterized by the fact that a cylindrical lock ( 3 ) is arranged in the grip of the weapon behind the magazine shaft, whose closing cylinder can be rotated with a key ( 7 ), that a transmission mechanism ( 6,4 ), which includes rods, levers, threading and the like, brings a blocking element ( 9 ) from a position in which it is situated outside the movement path of a part of the trigger mechanism of the weapon to a position in which it extends into the movement path of this part.

1 . Blocking device for a pistol with a trigger ( 27 ), a trigger mechanism ( 13 ) and a firing pin, hammer ( 23 ) or the like operated by them, characterized by the fact that the blocking mechanism consists of a cylindrical lock ( 3 ) arranged in the grip of the weapon, whose closing cylinder ( 15 ) can be rotated with a key ( 7 ), in which a transmission mechanism ( 6 ,  4 ), which includes rods, levers, threading and the like, brings a blocking element ( 9 ) from a position in which it is situated outside the movement path of a part ( 10 ) of the trigger mechanism ( 13 ) of the weapon into a position in which it extends into the movement path of this part ( 13 ), and that the cylindrical lock ( 3 ) and at least part of the transmission mechanism are arranged behind the magazine shaft ( 26 ).  
     
     
         2 . Blocking device according to  claim 1 , characterized by the fact that the rotational axis of the cylindrical lock ( 3 ) runs at least essentially parallel to the axis of the magazine shaft ( 26 ).  
     
     
         3 . Blocking device according to  claim 1  or  2 , characterized by the fact that the transmission mechanism includes a threaded piece ( 16 ) and a connector mount ( 22 ) that cooperates with it, through which the rotational movement of the closing cylinder ( 15 ) is converted to a translatory movement of the blocking element ( 9 ).  
     
     
         4 . Blocking device according to  claim 3 , characterized by the fact that the rotational movement of the closing cylinder is transferred to the threaded piece ( 16 ) by means of a rotating rod ( 6 ).  
     
     
         5 . Blocking device according to  claim 4 , characterized by the fact that the rotating rod ( 6 ) carries an essentially radially running pin ( 20 ) that rotates in a recess ( 21 ) of the connector mount ( 22 ), and that the recess ( 21 ) is connected to its surroundings by means of an essentially radially running slit ( 25 ).  
     
     
         6 . Blocking device according to one of claims  2 - 5  for a hammer pistol, characterized by the fact that a blocking tab ( 9 ′) extends into a notch, recess ( 24 ), etc. of a part that rotates together with hammer ( 23 ).  
     
     
         7 . Blocking device according to one of the preceding claims, characterized by the fact that an indicator ( 8 ) that extends outward through a slit in housing ( 1 ) of the weapon in the blocked position of the blocking device ( 14 ) is provided on lock ( 3 ).
