Handgun with a locking device

Abstract

Gun comprising a gun frame; a barre supported by the gun frame, proximally delimiting a firing chamber extending along a longitudinal axis; a slide, translatable longitudinally in relation to the barrel between a forward configuration wherein the slide closes the firing chamber, and a rearward configuration wherein it is distanced from a proximal mouth of the firing chamber, to open the latter; wherein orientation of said chamber is substantially parallel to said axis in the forward configuration and in the rearward configuration; and a locking device mechanically locking barrel and slide to each other in the forward configuration, and that in the rearward configuration is guided transversally in relation to the barrel for unlocking the slide. Slide and locking device delimit arched locking surfaces that in the forward configuration are coupled with each other for locking the slide, and that in the rearward configuration are mutually spaced in a transversal direction for opening said chamber.

         2 . The gun according to the  claim 1 , wherein the gun frame comprises said one or two guiding elements that project towards at least one of said arms to intercept and deviate the latter, in order to distance the locking device from the slide,
 and/or wherein   said one or two guiding elements interact with one or both said arms to guide the locking device from the forward configuration to the backward configuration,   and/or wherein   at least one guiding element of said one or two guiding elements comprises a pointed portion, directed towards the device arm.   
     
     
         3 . The gun according to  claim 1 , wherein at least one of said device arms comprises a first cam surface for promoting a transversal translation of the locking device with respect to the barrel. 
     
     
         4 . The gun according to  claim 3 , wherein at least one of said device arms delimits in its thickness said first cam surface, directed towards the guiding element. 
     
     
         5 . The gun according to  claim 4 , wherein the first cam surface and said arm surface extend along reciprocally incident planes, so as to delimit an arm cavity engageable by the one or two guiding elements, preferably by the pointed portion thereof. 
     
     
         6 . The gun according to  claim 1 , wherein the opposite movement of locking device from the backward to the forward configuration is performed by means of at least a second cam surface delimited by the gun frame, that contacts one or both said arms, preferably a distal surface thereof. 
     
     
         7 . The gun according to  claim 1 , wherein the locking device comprises at least a sliding projection that, in the rearward configuration, engages in a slidable manner a longitudinal rifling of the slide, and wherein
 the sliding projection is positioned on at least one of said device arms, and comprises a fin substantially parallel to the longitudinal axis.   
     
     
         8 . The gun according to  claim 1 , wherein the locking device is joined in translation to the barrel in a longitudinal direction, although with a freedom of movement in said transversal direction,
 and wherein   said slide and said locking device delimit arched locking surfaces that in the forward configuration are coupled with each other for locking the slide, and that in the rearward configuration are mutually spaced, preferably at least in said transversal direction, for unlocking the slide and opening said chamber.   
     
     
         9 . The gun according to  claim 8 , wherein one or both said arched locking surfaces at least partially enclose barrel, and/or
 wherein the arched locking surfaces extend along planes that are incident, preferably orthogonal, to the longitudinal axis, and/or   wherein in the rearward configuration, the arched locking surfaces are mutually directed in opposite directions, a first arched locking surface of the slide faces proximally, while a second arched locking surface of the locking device is directed distally.   
     
     
         10 . The gun according to  claim 8 , wherein the locking device comprises a shaped body, delimiting one of said arched locking surfaces, and/or
 wherein the locking device comprises a bent, originally straight, shaped body.   
     
     
         11 . The gun according to  claim 10 , wherein in the forward configuration, the shaped body is at least partially housed in a recessed locking seat, partially extending in the thickness of a top wall of the slide. 
     
     
         12 . The gun according to  claim 11 , wherein the shaped body is substantially U-shaped, and wherein said top wall delimits a bowed seat surface that delimits said seat on one side, directed towards the gun frame and shape-coupled to said body in the forward configuration. 
     
     
         13 . The gun according to  claim 1 , wherein said slide internally delimits a concave, preferably half-tubular, gliding surface that in the rearward configuration is in a gliding contact with the firing chamber, in particular with a top surface thereof. 
     
     
         14 . The gun according to  claim 12  and  claim 13 , wherein the bowed seat surface and the half-tubular gliding surface extend around parallel and non-coincident surface axes, wherein the radiuses of curvature of bowed seat surface and of the half-tubular gliding surface could be identical or dissimilar to each other,
 and wherein the above-mentioned surfaces are radially divided by a first arched locking surface delimited by the slide. 
 
     
     
         15 . The gun according to  claim 1 , wherein distally to the locking device, the barrel comprises a radial projection or a radial lip that extends towards the slide, such projection/lip interacts with the locking device, to move the latter from the forward to the backward configuration,
 and wherein the radial projection or radial lip makes an end-stroke for the slide during its proximal or backward movement in the rearward configuration, wherein said projection/lip is aligned in a direction substantially parallel to the longitudinal axis with an abutment tooth of the slide, so as to contact with the projection/lip.
