US12624908 - Break-barrel firearm

The present invention concerns a firearm comprising at least one frame; and a barrel group comprising at least one barrel, the barrel group being mounted in a tilting manner with respect to the frame, wherein the frame houses at least one closing device configured to act between the frame and the barrel group so as to selectively prevent the frame of the barrel group from tilting with respect to the frame, and is characterized in that the closing device comprises at least one pair of clamping elements with longitudinal development independent of each other, the clamping elements being slidably housed inside the frame, each along its own longitudinal development axis; and at least one pair of buffers each coupled to a respective clamping element so as to exert an axial thrust force on the respective clamping element substantially in parallel to and/or substantially along the respective longitudinal development axis.

The invention describes a break-barrel firearm featuring a frame and a tilting barrel group, with a closing device that selectively prevents the barrel group from tilting. This closing device includes independent clamping elements and buffers that exert axial thrust forces to maintain stability during operation.

Claim 1

1 . A firearm comprising at least: a frame; and a barrel group comprising at least one barrel, the barrel group being mounted in a tilting manner with respect to the frame, wherein the frame houses at least one closing device configured to act between the frame and the barrel group so as to selectively prevent the barrel group from tilting with respect to the frame, wherein the closing device comprises: at least one pair of clamping elements with longitudinal development independent of each other, the clamping elements being slidably housed inside the frame each along its own longitudinal development axis; and at least one pair of buffers each coupled to a respective clamping element so as to exert an axial thrust force on the respective clamping element substantially in parallel to and/or substantially along a respective longitudinal development axis. a frame; and a barrel group comprising at least one barrel, the barrel group being mounted in a tilting manner with respect to the frame, wherein the frame houses at least one closing device configured to act between the frame and the barrel group so as to selectively prevent the barrel group from tilting with respect to the frame, wherein the closing device comprises: at least one pair of clamping elements with longitudinal development independent of each other, the clamping elements being slidably housed inside the frame each along its own longitudinal development axis; and at least one pair of buffers each coupled to a respective clamping element so as to exert an axial thrust force on the respective clamping element substantially in parallel to and/or substantially along a respective longitudinal development axis.
