US 9,791,223 B2 · Firearm with pivoting barrel-receiver assembly

Abstract

A firearm with tilting barrel-receiver assembly 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 includes a latch that selectively engages the barrel-receiver assembly. The latching mechanism may be disposed in the frame in one embodiment. The latching mechanism is movable between a locked position wherein the barrel-receiver assembly is held in the closed position and an unlocked position wherein the barrel-receiver assembly is movable to the tilted open position. The latch may be spring biased into the locked position. The barrel-receiver assembly may be configured for complete removal from the pistol in some embodiments. An interlock mechanism formed by a movable safety may be provided which prevents the barrel-receiver assembly from being unlocked when the firearm is in a ready-to-fire condition.

Dependent claims

A firearm with tilting barrel-receiver assembly, the firearm comprising:

a longitudinal axis;
a frame;
a barrel-receiver assembly pivotably mounted to a front end of the frame, the barrel-receiver assembly angularly movable as a unit between a tilted open position and a closed position;
and
a latching mechanism disposed in the frame, the latching mechanism including a latch comprising a latch hook configured and operable to selectively engage or disengage the barrel-receiver assembly, and a rear actuating end projecting rearwards from the frame to actuate the latch;
the latch slideably movable in an axial direction in the frame 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;
wherein the barrel-receiver assembly includes a forwardly open locking recess which engages the latch hook when the latch is in the locked position, the latch hook projecting in a rearwards direction on the latch.

A firearm with tilting barrel-receiver assembly, the firearm comprising:

a longitudinal axis;
a frame;
a barrel-receiver assembly pivotably mounted to a front end of the frame, the barrel-receiver assembly angularly movable as a unit between a tilted open position and a horizontal closed position;
and
a latching mechanism disposed in the frame, the latching mechanism including a latch comprising a latch hook configured and operable to selectively engage or disengage the barrel-receiver assembly;
the latch slideably movable in an axial direction in the frame 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;
the frame including an upwardly extending pivot protuberance defining an arcuate pivot surface which is insertably received in a downwardly open elongated slot formed in the barrel-receiver assembly to pivotably mount the barrel-receiver assembly to the frame;
wherein the pivot protuberance and slot are obliquely angled to the longitudinal axis of the firearm and arranged such that the barrel-receiver assembly cannot be vertically lifted off the frame when the barrel-receiver assembly is in the horizontal closed position;
and
wherein the barrel-receiver assembly can be vertically lifted off the frame when the barrel-receiver assembly is in the tilted position.
