Definitions

  • the invention relates to a sports or hunting rifle with at least one barrel, each barrel being assigned a firing pin driven by a striking piece, a lock housing with a trigger device and at least one striking piece, the at least one striking piece being guided in an axially movable manner and - if several striking pieces are present - they are arranged one above the other, a tensioning device with a tensioning rod and a securing device.
  • the striking pieces are generally radially striking and arranged side by side. Because of this relatively wide construction of the lock housing, the barrel of the rifle is weakened in the lock area.
  • a rifle lock for a multi-barrel break barrel weapon in which striking elements, clamping elements and firing pins are arranged parallel to one another and can be moved in the same direction and these elements, which are designed as rotating parts, are guided in bores.
  • the invention relates to a rifle according to the preamble, in which the at least one striker has an angular, substantially rectangular shape in cross section and is accommodated in a lock housing which can be removed from the breech box.
  • the parallel movement of the striking pieces in the lock housing is approximately the same direction as the movement of the striking pin. This minimizes energy transmission losses; a relatively low impact energy is sufficient. With such an arrangement, the stroke distance is short, which correlates with a quick ignition. Due to a smaller energy, preferably stored in a helical spring, the force required for tensioning is correspondingly lower and the pull-off resistance is lower.
  • the cross-sectionally angular, preferably rectangular striking pieces with elevations and depressions, preferably with grooves or edges on the striking piece and corresponding edges or grooves on the lock housing, can be guided in the lock housing in a simple manner and are inexpensive to manufacture. It may be sufficient if the lock housing has only one side wall parallel to the level of the striking pieces, because the striking pieces can also be adequately guided from a side wall.
  • the lock housing can be made particularly narrow without sacrificing precision and stability.
  • the clamping pieces can be clamped directly by a linear movement of the clamping rod without any intermediate pieces; the movement of the tension rod and the movement of the striking pieces run approximately parallel.
  • a further preferred embodiment is characterized in that the end of the tension rod presses on the lower striker during tensioning and it stretches, an attachment is provided on the top striker which laterally overlaps the lower striker such that the end of the tension rod also opens when tensioned presses this approach and thus also tensions the upper striking piece. In this way, the simultaneous tensioning of the striking pieces arranged one above the other can take place without any special effort and without further deflection devices or translations.
  • a further development of the invention is characterized in that a guide pin for guiding a the striking coil spring is attached.
  • An advantageous embodiment of the rifle with the removable lock housing is characterized in that there are bores in the striking pieces, into which the coil springs partially protrude. In this way, a compact design can be achieved even with angular striking pieces.
  • the guide pin connected to the striking piece is particularly suitable for taking on additional securing tasks. It is advantageous if the guide pin is guided in the rear wall of the lock housing (facing away from the barrel) and is so long that it does not protrude from the rear wall of the lock housing when the striker is knocked off; protrudes from the rear that simple measures on the lock case can prevent the tips of the guide pins protruding from the lock housing, that the lock housing can be removed if only one guide pin still protrudes on the lock housing: the lock housing can only be removed and installed if both strikes are relaxed.
  • a pressure pin which has grooves and is arranged somewhat offset to the level of the guide pins in the lock housing so that the ends of the guide pins can only protrude from the rear wall of the lock housing if the guide pins can slide in the grooves of the pressure pin.
  • a switch must be available for the striking elements arranged one above the other.
  • the switchover can take place by means of a switch bolt which can be moved transversely to the direction of travel.
  • a switching bolt has the advantage that the shooter no longer has to let go of the barrel already encompassed for switching the barrel.
  • the transverse displacement of the switch pin is transferred to a switch rocker, which in turn adjusts an oscillating weight, by means of correspondingly running surfaces.
  • the oscillating weight is preferably displaceable perpendicularly to the plane of the striking pieces so that the oscillating weight engages only on one of the trigger rods of the upper or lower striking piece.
  • the swinging weight is rotatable in the plane of the striking pieces so that it only engages on one of the trigger rods of the upper or lower striking piece.
  • the lock housing Since the lock housing is very compact and in particular very narrow, the barrel of the rifle in the lock area is not weakened.
  • the lock housing is inserted in a form-fitting manner in the lock case.
  • a locking pawl has to be actuated, which clamps the lock housing best on the side facing away from the barrel and which should preferably only be operated when a safety slide attached to the top of the barrel is pushed back.
  • a lock housing 1 is matched to a corresponding approximately cuboid breech box 2 in the rifle.
  • a single locking pawl 50 is sufficient for fastening in the case of positive locking; it is only indicated by dashed lines in FIG. 2 in the rear wall 3 of the lock housing 1; it is arranged in the lock housing 1 offset to the level of the striking elements 4, 5 or the again slightly offset pressure pin 32.
  • the parallel, cross-sectionally impact pieces 4, 5 transmit the energy stored in tensioned coil springs 6, 7 to firing pins 8, 9.
  • the coil springs 6, 7 are pushed over guide pins 10, 11.
  • the striking pieces 4, 5 have bores 12, 13 into which the guide pins 10, 11 protrude. They are connected to the striking elements 4, 5 at the bottom of the bores 12, 13.
  • the bottom of the bore 12, 13 and the rear wall 3 of the lock housing 1 serve as counter bearings for the coil springs 6, 7
  • trigger rods 14, 15 are located in grooves 16, 17 of the striking elements 4, 5.
  • the trigger rods 14, 15 are pivotally mounted about pivot points 18, 19 and are supported on support points 20, 21.
  • the path of each striker 4, 5 to the striker 8, 9 is limited in a known manner by stops, not shown in the figure. Due to springs 22, 23, the trigger rods 14, 15 engage at the support points 20, 21 during tensioning.
  • the guide pins 10, 11 for the coil springs 6, 7 also perform an important securing function.
  • the tips 27, 28 of the guide pins 10, 11 protrude from the rear wall 3 of the lock housing 1 in the tensioned state. Edges 29, 30 matched to the tips 27, 28 of the guide pins 10, 11 are present in the breech box 2 in the rifle, which in a simple manner prevents the lock housing 1 from being released from the breech box 2 (in the drawing downward) can be removed.
  • the pressure pin 31 is inserted into the rear wall 3 of the lock housing 1 in such a way that when it is pressed by a matching pin 32 in the lock box 2 (downwards in the drawing), it becomes possible for the tips 27, 28 of the guide pins 10, 11 can be inserted through the rear wall 3 because grooves 33, 34 in the push pin 31 push the guide pins 10, 11 past the "obstacle push pin” 31 which is offset somewhat from the plane of the striking pieces 4, 5 enable.
  • the striking pieces 4, 5 are tensioned by a tensioning rod 36.
  • the tensioning rod 36 moves towards the lock housing 1 and thereby pushes the front side 37 of the lower striking piece 5 - if it should have been relaxed - against the coil springs 7 in the breech housing 1 until the trigger rod 15 engages behind the support point 21.
  • the tensioning of the striking piece by the tensioning rod 36 is particularly inexpensive and mechanically very simple.
  • both or each striker can be individually tensioned by the tension rod 36 be recorded. This means that both striking elements 4, 5 can be brought back into the cocked position when the barrels tip over, provided they have not remained cocked.
  • the striking elements 4, 5 are released via a trigger lever 39 about a pivot point 40.
  • a trigger arm 41 is located in a bore in the trigger lever 39 is arranged to be longitudinally displaceable, raised, it in turn takes the swing weight 24 with it.
  • the swing weight 24 is blocked by the safety slide 42; when it is pushed into a central position (FIG. 2), in FIG. 1, as in FIG.
  • the swinging weight 24 can tilt somewhat by a spring 43 around a pivot point 48 and the upper catch 25 on the swinging weight 24 is brought into a positive connection with the upper trigger rod 15, so that the upper catch 25 releases the blockage of the upper striking piece 4 when the oscillating weight 24 is moved again.
  • the shooter wants the upper striker 4 to be triggered first (FIG. 1), he only needs to move a switch pin 44.
  • the movement of the switching pin 44 takes place transversely to the plane of the striking pieces 4, 5.
  • In the switching pin 44 there is a groove with an inclined position, into which a ball head 45 is guided in connection with a switching rocker 46 so that the switching rocker 46 is about a pivot point 47 at Switching swiveled.
  • the longer arm of the switching rocker 46 runs in a backdrop of the trigger arm 41 and moves it backwards.
  • the swing weight 24 movable about the pivot point 48 comes out of engagement with the trigger rod 15 at the catch 26, while the upper catch 25 engages with the swing weight 24 in the upper trigger rod 14. This has reversed the sequence of shots.
  • the oscillating weight 24 is automatically engaged with the lower trigger rod 15 (FIG. 2).
  • lock housing 1 If the lock housing 1 is to be removed, only one locking pawl 50 in the rear wall 3 of the lock housing 1 is to be actuated. It makes sense if the actuation of the spring-loaded locking pawl 50 can only take place in the securing of the safety slide 42 on the top of the rifle.
  • the pressure pin 31 When the lock housing 1 is removed, which is only possible with relaxed strikers 4, 5, the pressure pin 31 is displaced in the axial direction by the spring 35, whereby a state is automatically reached in which the strikers 4, 5 cannot be tensioned.
  • a trigger guard 49 is integrally connected to the lock housing 1.
