Automatic pistol

Abstract

Provided is an automatic pistol comprising a frame with frame guides, a barrel arranged on the frame guides of the frame, a breech and a closing and locking device. The closing and locking device comprises a rod with a closing spring and further comprises a guide bushing, wherein the guide bushing is couplable to the rod and wherein the rod comprises lateral locking elements at its rear end. The frame also has symmetrically arranged inclined grooves designed to receive the locking elements of the rod, so that the rod is guided from an inclined position (locking position) to a horizontal position (unlocking position) and vice versa as a result of a shot from the gun.

1 . Automatic gun comprising:
 A frame ( 1 ) having frame guides,   a barrel ( 3 ) arranged on the frame guides of the frame ( 1 )   a shutter ( 2 ), and   a closing and locking device,   characterized in   that the closing and locking device comprises a rod ( 4 ) with a closing spring ( 8 ) and further comprises a guide bush ( 7 ), wherein the guide bush ( 7 ) can be coupled to the rod ( 4 ) and wherein the rod ( 4 ) comprises lateral locking elements ( 5 ) at its rear end, and   in that the frame ( 1 ) further has symmetrically arranged inclined grooves ( 9 ) which are designed to receive the locking elements ( 5 ) of the rod ( 4 ), so that the rod ( 4 ) is guided from an oblique position (locking position) into a horizontal position (unlocking position) and vice versa as a result of a shot from the pistol.   
     
     
         2 . Automatic pistol according to  claim 1 , further comprising:
 two frame pins ( 14 ) which are arranged opposite each other in the frame ( 1 ),   wherein the guide bush ( 7 ) is rotatably arranged on the frame pins,   wherein the closing fields ( 8 ) in the locking position exert a spring force on the guide bushing ( 7 ), the line of force of which runs above the axis of rotation of the guide bushing ( 7 ), and   wherein in the unlocked position the closing fields ( 8 ) exert a spring force on the guide bushing ( 7 ), the line of force of which extends below the axis of rotation of the guide bushing ( 7 ).   
     
     
         3 . Automatic gun according to  claim 1 , further comprising:
 a recoil limiting element ( 6 ), which is arranged in a frame guide groove ( 21 ) of the frame ( 1 ) provided for this purpose and the movement clearance of which is limited during recoil by a rear wall of the frame guide groove ( 21 ) and during forward travel by a barrel retaining lever ( 10 ) fastened in the frame ( 1 ),   wherein the support element ( 7 ) is rotatably arranged on the barrel retaining lever ( 10 ),   wherein the closing fields ( 8 ) in the locking position exert a spring force on the guide bush ( 7 ), the line of force of which runs above the axis of rotation of the guide bush ( 7 ), and   wherein, in the unlocked position, the closing fields ( 8 ) exert a spring force on the guide bushing ( 7 ), the line of force of which runs below the axis of rotation of the guide bushing ( 7 ).   
     
     
         4 . Automatic gun according to one of the preceding claims, wherein the lateral locking elements ( 5 ) of the rod ( 4 ) each have a rear slope ( 15 ) and a front slope ( 16 ), the course of which corresponds to the course of the inclined grooves ( 9 ) of the frame ( 1 ). 
     
     
         5 . automatic pistol according to one of the preceding claims, wherein two locking projections ( 11 ) arranged symmetrically to one another are formed in the shutter ( 2 ). 
     
     
         6 . automatic pistol according to  claim 5 , wherein the lateral locking elements ( 5 ) of the rod ( 4 ) are further adapted to engage the locking protrusions ( 11 ) of the shutter ( 2 ) in the locking position and to effect a locking.
