Gun

Abstract

Gun comprising a gun frame, a barrel supported by the gun frame, a slide, translatable longitudinally in relation to the barrel, and at least a hammer, rotatably mounted with respect to the gun frame so as to move at least a firing pin of said gun towards the barrel. A centreline plane crosses said gun between opposite gun flanks, and the rotation axis of said hammer lies in the centreline plane or is substantially parallel to said plane.

1 . Gun comprising:
 a gun frame;   a barrel supported by the gun frame;   a slide, translatable longitudinally in relation to the barrel;   at least a hammer, rotatably mounted with respect to the gun frame so as to move at least a firing pin of said gun towards the barrel;   
       wherein a centreline plane crosses said gun between opposite gun flanks; said gun being characterized in that the rotation axis of said hammer lies in the centreline plane or is substantially parallel to said plane. 
     
     
         2 . Gun according to  claim 1 , wherein the barrel extends along a longitudinal direction, the rotation axis being substantially perpendicular to the longitudinal direction. 
     
     
         3 . Gun according to  claim 1 , wherein the hammer is integral with the slide during the translational movement of the latter, and is hingedly connected to said slide. 
     
     
         4 . Gun according to  claim 1 , comprising a rotation pin of the hammer, extending along the rotation axis and at least partially housed in the thickness of a slide wall. 
     
     
         5 . Gun according to the previous  claim 4 , wherein the slide wall delimits a rotation bore wherein the rotation pin is partially inserted, said bore passing completely through the thickness of said wall and being open towards a top surface of the slide, e.g. so as to enable lubrication operations. 
     
     
         6 . Gun according to  claim 1 , wherein the hammer is completely housed within a slide compartment of the slide, in each angular position thereof, said compartment being delimited at least in part by the gun frame. 
     
     
         7 . Gun according to  claim 1 , wherein the hammer has generically or substantially the shape of a solid of revolution. 
     
     
         8 . Gun according to  claim 1 , comprising elastic means forcing constantly the hammer towards a firing position, and at least a retention member for mechanically retaining the hammer in an armed position in contrast to the force exercised by the elastic means, said retention member being movable by means of a trigger for releasing said hammer towards the firing position. 
     
     
         9 . Gun according to  claim 1 , comprising elastic means engaged between the slide and a first engagement element of the hammer, and wherein the firing pin is urged by a second engagement element of the hammer towards the barrel. 
     
     
         10 . Gun according  claim 9 , wherein the first and the second engagement elements are eccentrically positioned in relation to the rotation axis. 
     
     
         11 . Gun according to  claim 9 , wherein the first and the second engagement elements project from opposite surfaces of a hammer body, said surfaces being located one above and one below an intermediate orthogonal plane of said body with respect to the rotation axis. 
     
     
         12 . Gun according to  claim 9 , wherein the first and the second engagement element each comprise an element pin developing substantially parallel to the rotation axis. 
     
     
         13 . Gun according to  claim 9 , wherein the first engagement element and/or the second engagement element are located in a sector-shaped depression of the hammer angularly delimited by hammer surfaces, rotation of the hammer bringing alternatively one of said surfaces in abutment with the elastic means and/or with the firing pin so as to determine end-stroke positions of the hammer. 
     
     
         14 . Gun according to  claim 13 , wherein the hammer surfaces extend axially along the rotation axis. 
     
     
         15 . Gun according to  claim 1 , wherein the firing pin comprises a pin body connected with the hammer, and a pin tips extending distally towards the barrel, the pin body and the hammer being connected by means of a cam mechanism. 
     
     
         16 . Gun according to  claim 15 , wherein the pin body delimits a pin slot wherein the second engagement element or a second element pin is partially lodged, and wherein the surfaces delimiting said slot make cam surfaces for moving the pin tip towards, and for distancing the pin tips from, the barrel. 
     
     
         17 . Gun according to  claim 8 , wherein the barrel proximally delimits a firing chamber and wherein, in the firing position, the firing pin partially projects into said chamber, orientation of the firing chamber being substantially parallel to a longitudinal direction in every moment of the firing cycle of said gun. 
     
     
         18 . Gun according to  claim 1 , characterized by the fact of being a semi-automatic or an automatic handgun.
