A barrel locking mechanism for a break-open-action gun having a barrel and a mechanical section rotatably engaged with each other by a hinge-pin. It has a lug secured to the barrel and having a delining surface. While a stationary receiver is integrally mounted on the mechanical section. On the top of it, a movable receiver having a delining surface corresponding to that of the lug is vertically movably mounted through a spring. When the gun is locked, the lug moves downwards depressing the movable receiver against the spring. As a result, intimate contact of the corresponding surfaces is obtained in order to receive the load when the gun is discharged.
A break open sporting firearm with one to four barrels that lock up in line directly behind the chambers for strength and rigidity. The load from firing is taken up by two or more circularly spaced lugs in the breech engaging with mating lugs on the frame. A rotating breech plate slider and hinge within the breech are the functioning means for this invention.
A folding firearm comprises a stock supporting a receiver, the receiver defining a bore for receiving a first end of the firearm barrel. A forearm is operably pivotally connected to the stock. The forearm includes a barrel securing mechanism having a securement member. The firearm barrel has a surface adjacent to the first end for engaging the securement member. The securement member is matingly engageable with the surface of the barrel. The securement member, in response to pivotal movement by the forearm, moves into engagement with the surface to urge the first end of the barrel into the bore of the receiver when the firearm is pivoted into a firing position. The firearm also includes a locking mechanism capable of selectively locking the forearm in the firing position.
A barrel retaining device for an automatic pistol has a locking element that locks the pistol barrel and breech both of which are guided on the stock of the weapon. In order to remove the breech with the barrel from the stock in order to disassemble the pistol, the locking element has an actuating element on both sides of the stock which, when depressed, unlocks a lock between the barrel and the stock. At the same time, depressing of the actuation element releases the trigger finger into a forward position to impart a forward movement to a spring loaded trigger arm which is also cammed downwardly to disengage the trigger arm and the driver on the firing pin in the breech. The connections between the breech and the stock are thus released by a single unlocking movement when disassembling a pistol.
