Abstract

A firearm (1) comprising a firearm frame (2) which delimits at least one first friction surface (6, 6′); one barrel (4, 4′), mounted to said frame (2) in a rotatable manner (A1) between opening and closing configurations and comprising an abutment appendix (8); and an adjustment device (10). Such a device comprises: 1) a second friction surface (12) placed in a sliding contact with the first friction surface (6, 6′) to oppose a resistance to the rotation of the barrel (4, 4′) between the configurations; ii) a contact surface (14) with the abutment appendix (8); iii) an adjustment member (16), longitudinally movable (LI, L2) for modifying a relative distance between the second friction surface (12) and the contact surface (14), thereby adjusting the sliding friction between said friction surfaces (6, 6′, 12); and iv) a maneuvering element (18) rotatable in discrete adjustment positions, interacting with the adjustment member (16) to move it by a constant pitch at each angularly adjacent adjustment position.

Abstract

A firearm (1) comprising a firearm frame (2) which delimits at least one first friction surface (6, 6'); one barrel (4, 4'), mounted to said frame (2) in a rotatable manner (Al) between opening and closing configurations and comprising an abutment appendix (8); and an adjustment device (10). Such a device comprises: 1) a second friction surface (12) placed in a sliding contact with the first friction surface (6, 6') to oppose a resistance to the rotation of the barrel (4, 4') between the configurations; ii) a contact surface (14) with the abutment appendix (8); iii) an adjustment member (16), longitudinally movable (LI, L2) for modifying a relative distance between the second friction surface (12) and the contact surface (14), thereby adjusting the sliding friction between said friction surfaces (6, 6', 12); and iv) a maneuvering element (18) rotatable in discrete adjustment positions, interacting with the adjustment member (16) to move it by a constant pitch at each angularly adjacent adjustment position.

Abstract

The firearm comprises a firearm frame, a barrel sleeve mounted in a rotatable manner on the firearm frame, and at least one rotation pin which extends between the firearm frame and the barrel sleeve to guide the sleeve around a rotation axis. The rotation pin and the firearm frame, or said pin and the barrel sleeve, lie in abutment with each other by means of complementary sliding surfaces, at least one sliding surface being borne by a wear component connected in a releasable manner to the rotation pin, to the firearm frame and/or to the barrel sleeve. The invention also relates to a kit for a firearm.

• F41A 3/06 - Block action, i.e. the main breech opening movement being transverse to the barrel axis with pivoting breech-block about a horizontal axis transverse to the barrel axis at the rear of the block
• F41A 3/58 - Breakdown breech mechanisms, e.g. for shotguns
• F41C 7/11 - Breakdown shotguns or rifles
