US12546549 - Firearm
The patent describes a firearm featuring a frame, barrel, hand grip, and a breechblock that slides along the frame, with a striker and a recoil recovery mechanism. A closing block is incorporated to lock the breechblock in place during firing, allowing for efficient energy recovery and rearming of the striker.
Claim 1
1 . A firearm, comprising: a frame; a barrel which has a longitudinal axis arranged in a median plane which divides said gun into a right part and a left part; a hand grip; a breechblock slidable along the frame parallel to the longitudinal axis of the barrel for closing of a breech of the barrel; a striker slidable in the breechblock parallel to the longitudinal axis of the barrel; a longitudinal elastic device for recovery of recoil kinetic energy of the breechblock for rearming the striker; and further comprising a closing block, supported by said frame in a movable way in said plane of the gun along an inclined direction with respect to the axis of the barrel and engageable with the breechblock for locking the breechblock in the closing position, said closing block having a body which extends longitudinally in a parallel direction to said axis of the barrel and having a rear wall engaged with a downward protrusion integral with the barrel, a front wall engageable with the breechblock and a longitudinal recess which opens at said front wall, where said closing block acts on said downward protrusion during a firing cycle, causing the barrel to move backwards, where said longitudinal elastic device for the recovery of kinetic energy has a longitudinal rear portion housed in said longitudinal recess of the closing block and a longitudinal front portion retractable towards the inside of said longitudinal recess, and is longitudinally interposed between a front stop abutment solidly constrained to said breechblock and a rear stop abutment solidly constrained to said frame. a frame; a barrel which has a longitudinal axis arranged in a median plane which divides said gun into a right part and a left part; a hand grip; a breechblock slidable along the frame parallel to the longitudinal axis of the barrel for closing of a breech of the barrel; a striker slidable in the breechblock parallel to the longitudinal axis of the barrel; a longitudinal elastic device for recovery of recoil kinetic energy of the breechblock for rearming the striker; and further comprising a closing block, supported by said frame in a movable way in said plane of the gun along an inclined direction with respect to the axis of the barrel and engageable with the breechblock for locking the breechblock in the closing position, said closing block having a body which extends longitudinally in a parallel direction to said axis of the barrel and having a rear wall engaged with a downward protrusion integral with the barrel, a front wall engageable with the breechblock and a longitudinal recess which opens at said front wall, where said closing block acts on said downward protrusion during a firing cycle, causing the barrel to move backwards, where said longitudinal elastic device for the recovery of kinetic energy has a longitudinal rear portion housed in said longitudinal recess of the closing block and a longitudinal front portion retractable towards the inside of said longitudinal recess, and is longitudinally interposed between a front stop abutment solidly constrained to said breechblock and a rear stop abutment solidly constrained to said frame.
