Abstract
A firearm with tilting barrel-receiver assembly. In one embodiment, the firearm includes a frame and a barrel-receiver assembly pivotably mounted to the frame. The barrel-receiver assembly is movable between an open position and a closed position. A latching mechanism may include a slide plate configured to selectively engage the frame. The latching mechanism is movable between a locked position wherein the barrel-receiver assembly is held in the closed position by the slide plate and an unlocked position wherein the barrel-receiver assembly is movable to the tilted open position. The slide plate may be spring biased into the locked position. An actuator button cooperates with the slide plate for moving the latching mechanism between the locked and unlocked positions.
Claims19
A firearm with tilting barrel-receiver assembly, the firearm comprising:
- a longitudinal axis;
- a frame;
- a barrel-receiver assembly pivotably supported by the frame, the barrel-receiver assembly angularly movable between a tilted open position and a closed position;
- and
- a latching mechanism disposed in the barrel-receiver assembly, the latching mechanism including a slide plate configured and operable to selectively engage or disengage the frame;
- the slide plate slideably movable between a locked position in which the barrel-receiver assembly is retained in the closed position, and an unlocked position in which the barrel-receiver assembly is movable to the open position:, and
- a vertically oriented latch pin mounted to the frame which is engaged or disengaged by the slide plate;
- wherein the latch pin includes a locking slot that is engaged or disengaged by the slide plate.
A pistol with tilting barrel-receiver assembly, the pistol comprising:
- a longitudinal axis;
- a grip frame defining a front trigger guard portion and a rear magazine well;
- a barrel-receiver assembly pivotably supported by the frame, the barrel-receiver assembly including a barrel coupled to a receiver, the barrel-receiver assembly angularly movable between a tilted open position and a closed position;
- a reciprocating bolt movably disposed in the barrel-receiver assembly for forward and rearward movement along the longitudinal axis;
- a bolt stop pin rigidly attached to the frame, the bolt stop pin arranged to engage the bolt to limit the forward movement of the bolt;
- and
- a latching mechanism disposed in the barrel-receiver assembly, the latching mechanism including a slide plate configured and operable to slidably engage the bolt stop pin in a locking manner;
- the slide plate axially movable between a locked position in which the slide plate engages the bolt stop pin to prevent the barrel-receiver assembly from being moved out of the closed position, and an unlocked position in which the slide plate disengages the bolt stop pin to allow the barrel-receiver assembly to move to the open position;
- wherein the slide plate engages a locking slot formed in the bolt stop pin when the slide plate is in the locked position.
A method for operating a firearm with tilting barrel-receiver assembly, the method comprising:
- providing a firearm including a longitudinal axis and a frame supporting a barrel-receiver assembly pivotably movable from a closed position to a tilted open position;
- moving the barrel-receiver assembly from the open to closed position;
- inserting a latch pin disposed in the frame through a slide plate movably disposed in the barrel-receiver assembly;
- axially sliding a slide plate in a first direction into mutual engagement with the latch pin;
- and
- locking the barrel-receiver assembly in the closed position wherein the barrel-receiver assembly cannot be moved to the open position:,
- wherein the inserting step includes inserting the latch pin through a locking aperture formed in the slide plate, a top end of the latch pin projecting above a top surface of the slide plate;
- wherein the locking step includes engaging a locking ledge projecting into the locking aperture with a locking slot formed in the latch pin.
