Safety device for revolvers

Abstract

The present invention concerns a safety device for a firearm such as a revolver, which includes a flexible, elastic element ( 24 ) fixed to the hammer and having a free end ( 26 ) interacting with the tail of a cylinder blocking lever ( 13 ) to move the latter from an active block position to an inactive release position of the cylinder consequent to a rotation of the hammer from a rest position to a cocked position passing through an intermediate, safety half-cocked position.

1 . Safety device for a firearm such as a revolver, which includes a body housing a cylinder for the ammunition, a cylinder blocking lever to stop the cylinder in each of a plurality of angular positions, a hammer, a trigger controlling the hammer and a firing pin controlled by the hammer in order to fire each cartridge, where the cylinder blocking lever ( 13 ) rocks on a pin ( 13 ′) and moves between an active cylinder block position and an inactive cylinder release position, and where said cylinder blocking lever has, on one side of said pin, a nose ( 17 ) designed to engage and block the cylinder and, on the other end, a tail ( 18 ) facing towards the hammer and designed to interact with said hammer, wherein an attached flexible, elastic element ( 24 ) is fixed to the hammer and has a free end ( 26 ) interacting with the tail ( 18 ) of said cylinder blocking lever ( 13 ) to move this from the active block position to the inactive release position of the cylinder consequent to a turn of the hammer from the rest position to the cocked position passing through an intermediate safety, half-cocked position.  
     
     
         2 . Safety device according to  claim 1 , wherein said elastic element comprises a flexible blade ( 24 ) fixed to the hammer remaining within the shape of the hammer.  
     
     
         3 . Safety device according to  claim 2 , wherein said elastic blade ( 24 ) is positioned and set in a recess provided in one side of the hammer and is on a plane containing the tail of the cylinder blocking lever, the elastic blade acting on the side of the cylinder locking lever.  
     
     
         4 . Safety device according to  claim 3 , wherein the free end ( 26 ) of said elastic blade ( 24 ) has a rounded or bevelled end portion, and the tail ( 18 ) of the cylinder blocking lever ( 13 ) has, in cross section, a lateral inclined plane starting from the top side of said tail.  
     
     
         5 . Safety device according to  claim 4 , wherein the cylinder blocking lever has a solid cross section tail.  
     
     
         6 . Safety device according to  claim 4 , wherein the free end ( 26 ) of said elastic blade ( 24 ) is positioned below the tail ( 18 ) of the cylinder blocking lever ( 18 ) when the hammer is in the rest position, moves the cylinder blocking lever in the inactive position when the hammer is or passes into the intermediate safety, half-cocked position, is located above the tail of the cylinder blocking lever when the hammer is in the cocked position, and passes alongside said tail when the hammer moves into the rest position.
