Definitions

  • the present invention relates to the technical field of firearms, in particular shotguns with manual feeding of cartridges into a barrel or into two barrels lying one above the other.
  • the lock mechanisms are actuated due to the movement of the barrels around a pivot point near the front of the base. Such tipping of the barrels also allows the rear of the barrel or both barrels to be released to insert the cartridges.
  • the articulated connection should also be formed in such a way that the frame and the barrels can be easily coupled and uncoupled from one another.
  • a disadvantage of the known solutions for this is that after long use of the shotgun, certain games occur between the joint parts on the barrels and those of the barrel. In addition, an axial pressure is exerted on the barrels when the shot is fired, which reduces the wear of said Ge steering parts accelerated.
  • the axial pressure which arises when the shot is fired causes a partial force which creates a bending moment which acts on the side walls of the base and tends to open outward.
  • the present invention is therefore based on the object of providing an articulated connection in which a partial force arises during the development of the shot, which generates a bending moment which closes the side walls of the crest inwards, thereby delaying the development of the games.
  • an articulated connection arranged between the base and the shotgun barrels, which is characterized in that it has two coaxial pairs of articulated parts, the articulated parts of each pair complementing one another and attached to the said base and to the corresponding side wall of the or the barrels are formed and have a matching coupling profile, so that the axial pressure which arises when the shot is fired generates a partial force perpendicular to this axial pressure which counteracts the bending moment which causes the two side walls of the base to spread apart.
  • the joint part on the side walls 1b of the basket 1 is indicated by reference number 1a
  • the complementary joint part arranged on the side wall 2, which is formed in one piece with the barrels 2o of a shotgun 3o is indicated by reference number 2a.
  • the joint parts 1a are arranged on the inside in the front region of the side walls 1b facing the barrels 2o and are manufactured in one piece with them or, in the case of separate production, subsequently connected to them, for example by welding, soldering, gluing or the like.
  • Reference number 2b indicates the opening zone of the joint part 2a, which permits the insertion and / or removal of the above-mentioned barrels 2o into or out of the basket 1.
  • the hinge parts 1a and 2a are designed so that 5 not only the usual connection in the longitudinal or axial direction of the base or barrel, but also Lich also a positive locking between the side walls 1b and the barrels 2o transverse to the firing direction, as shown in more detail in Fig.2 and 3.
  • the barrels 2o are locked in the firing position with the base 1 by hooking elements 3, which are arranged on the side walls 1b of the base and are designed such that they engage in the recesses 4 provided on the side walls of the barrels.
  • the profile P1 of the joint parts 1a shown in FIG. 2 has a truncated cone shape, the smaller top surface of which faces the side walls 1b.
  • the profile P2 of the embodiment according to FIG. 3, likewise shown in the view, has a "T-shape" in that the joint part 1a is designed as a stepped circular cylinder which is arranged with its smaller diameter area facing the side walls 1b, and its small area is located on said side wall 1b of the base 1.
  • the hinge parts 2a which are attached to the side wall 2 on the outside, complement the profiles P1 and P2 of the hinge parts 1a by being formed with corresponding undercuts which prevent the hinge parts 1a from “snagging” (positive connection) in them not only in the axial direction, but also perpendicular to it, ie transverse to the shot direction in the horizontal direction
  • the force acting on the barrels 2o in the axial direction which develops due to the gas pressure when the shot is fired, causes a shear stress on the joint parts 1a, to which is added the bending moment which is also caused by the gas pressure and acts on the side walls 1b.
