Definitions

  • the invention is directed to a barrel-barrel weapon with at least one barrel and a cartridge ejection device in the monoblock, which has a cartridge ejector that is movable in the barrel direction per barrel, which when tilting the barrel via a cam on the cartridge extractor and a corresponding guidance of the cam in the breech box from a retrieved into a pre-selected position is movable and makes a reverse movement when stretching, whereby an ejector spring can also be tensioned when the barrel is stretched, and a control bolt leading through the barrel wall is present per barrel, which after firing a shot causes the cartridge ejector to tip in one when tipped Tension position remains, and the tension position can only be canceled when the barrel is completely tilted.
  • the mechanical control of the ejection device by the trigger mechanism is by a control about the gas pressure that arises when a cartridge is fired in the chamber.
  • a control pin is embedded in the wall of each barrel, which is moved somewhat outwards by the widening sleeve wall, and this minimal movement of the control pin causes the tip of the control pin to positively engage in the cartridge extractor and hold it in a tensioned position can.
  • an ejector pawl at the end of the tipping of the barrel, this connection is canceled and the impulse transmitted jerkily from a tensioned spring to the ejection device is used to eject the cartridge case.
  • the cartridge ejection device described in EP 103 568 B1 has the disadvantage that other disadvantages had to be accepted in the implementation of this idea.
  • the control of the clamping device is housed between the barrel and the cartridge extractor, which is extremely unsatisfactory from a manufacturing point of view.
  • the slight movement of the control pin in the running wall by only a few tenths of a millimeter also has a negative impact on reliability, especially since it is impossible to readjust or rework this structure.
  • the object of the invention is to alleviate the disadvantages mentioned and to increase the durability and reliability of the weapon.
  • the invention relates to a barrel-barrel weapon according to the preamble, which is characterized in that there is a control flap attached to the outside of the monoblock with a detent, the control flap is movable about an axis transversely to the direction of travel, the control pin does not act on the cartridge ejector, but after delivery of a Shot raises the control flap so that when the control bolt is extended, the catch on the control flap hits an edge on the cartridge ejector and as a result, the cartridge ejector initially remains in the tensioned position when the barrel is tilted further, whereas the movement of the cartridge extractor is not impeded when the control flap is not deployed.
  • control pin does not act on the cartridge ejector directly from the barrel side, but that in addition to the control pin there is also a control flap which is easily accessible from the outside and whose switching path can be increased due to the leverage effect on the movement of the control pin, and this control element is much easier to handle in terms of production technology, which increases the reliability of the weapon.
  • the movement of the front edge of the catch on the control flap is in the same direction as the movement of the control pin.
  • the cartridge ejector is constructed from two parts, the term cartridge extractor being used for the part of the cartridge ejector which engages the cartridge edge, and the second part of the cartridge ejector, which takes over the control of the cartridge extractor, being referred to as an extractor element.
  • the cartridge extractor can be guided in a round hole. There is enough space for such a hole in the monoblock and such a guide does not weaken the monoblock. With a round guide, the cartridge extractor can be of the same design for each barrel, only the extractor elements are different, depending on which side of the barrel they are used for. Protection from twisting the cartridge extractor can be taken over by the extractor element, since the extractor element is secured against twisting by grooves. In advantageous The radial guidance of the cartridge extractor is achieved by means of two mutually facing longitudinal surfaces on the extractor element and on the cartridge extractor, the surfaces allowing the mutual distance between the cartridge extractor and extractor element to change, as will be described later.
  • the cartridge extractor and extractor element are coupled via a spring, the path of the cartridge extractor being equal to or less than the path of the extractor element which is positively guided by cams. In this way it can be ensured that the cartridge extractor is fully retracted before the closing process is completed and the cartridge can slide into the cartridge chamber through the breech block without pressure.
  • the spring reduces the impact load on the cartridge extractor and thus improves the durability and reliability of the weapon.
  • the ejector spring is usually covered by the fore-end.
  • the cartridge ejector is pulled in completely by a control cam via the control cam in the breech box before the barrels are tipped into the breech box.
  • the spring is stretched or compressed between the extractor element and the cartridge extractor, depending on whether it is designed as a tension or compression spring. There are no overloads on the cartridge extractor, which has already been fully retrieved, and on the extractor element which is moved by the cams.
  • the control pin is secured by steps to prevent it from penetrating too far into the barrel, from falling out and from twisting.
  • the ejector spring which is tensioned when the barrels are stretched, should preferably no longer act on the cartridge ejector when the cartridge ejector has traveled 80-90% of its way. Damping elements on the ejector spring should also be preferred acted upon pressure pin or provided on the extractor element to dampen noise. In a preferred embodiment, the movement of the control flap is also damped, preferably by a rubber or plastic ring on the cam of the extractor element.
  • One embodiment is characterized in that the control flap is guided in a hinge-like manner by tabs and grooves on the monoblock.
  • a further advantageous embodiment is characterized in that an externally accessible stud screw is provided on the monoblock, by means of which, when it is fully screwed in, movement of the control flap by the control bolt can be prevented. In this way, the automatic ejection can be switched off easily.
  • control device is characterized in that a spring is pressed against the control flap from the monoblock.
  • the control device can be made "stiff", whereby the reliability can be increased still further, because a lifting of the control flap without a shot being fired can be excluded with certainty.
  • the cartridge extractors and their guidance in multi-barrel weapons are designed such that a uniform type can be used for each barrel.
  • FIG. 1 shows a monoblock 1 with two barrels 2, 3 in the pre-fetched position of the cartridge extractor 4. This position is always assumed when the barrel is completely bent. If no shot has been fired, the cartridge extractor 4 holding the cartridge sleeve 4 gradually moves into this position during tilting due to the ejector spring 5 designed as a compression spring. When a shot has been fired, the cartridge extractor 4 engages in a clamping position, as shown in FIG. 2. The blockage of the cartridge extractor movement is only lifted when the barrel is completely tilted. This is done in that the control flap is pressed inwards by an extension in the area of the hinge of the lock box and thus the catch 17 releases the cam 6. The empty cartridge case is ejected by the pulse transmitted by the ejector spring 5.
  • the movement of the cartridge extractor 4 takes place via a cam 6 which is positively guided in the lock box in such a way that the cartridge extractor is guided from the retrieved to the retrieved position when tilted or from the retrieved to the retrieved position when closing.
  • cams are attached to both sides of the barrels.
  • a control pin 7 is embedded in the wall of the barrel 2, the control pin is shown in section in FIG. 3. It has a shoulder 8 which abuts a corresponding edge in the running wall. This ensures that the tip 9 of the control bolt 7, which is adapted to the cartridge case, does not protrude too far into the barrel.
  • An edge 10, created by milling on the other side of the control pin 7, enables the control pin 7 to be supported on a control flap 11, thereby protecting it from twisting and falling out.
  • the control flap 11 is movable about an axis 12. It is shown in Figure 4. It has a longer arm 13. If the control pin 7 pushes the control flap 11 slightly away from the barrel (in the drawing in FIGS. 1 and 2 from the plane of the drawing), the movement thereby caused at the end 14 of the arm 13 leads to a movement opposite the pin increased movement. On the control flap 11 there are connecting flaps 15 which, in conjunction with corresponding grooves 16 (FIG. 8) in the monoblock 1, act as a hinge.
  • the control flap 11 has a catch 17 which corresponds to an edge on the cam 6 of the cartridge ejection device. As will be explained further below, the cartridge ejector is in two parts and the cam 6 is fastened to an ejector element (FIG. 6) which is connected to the cartridge extractor 4 via a spring, but this is of no importance for the function of the catch.
  • the ejector spring 5 is guided by a bolt 19, which in turn is held in a spring counter bearing plate 20a by a bushing 20 and is guided axially displaceably in a bore in the monoblock 1; the bolt 19 has a collar 21 towards the monoblock 1 which, like the bushing 20, serves as a spring counter bearing.
  • the position of the collar 21 on the bolt 19 is determined so that in the pre-fetched position of the cartridge extractor 4 there is still some play for the cartridge extractor 4 (5-15% of the total travel).
  • FIGS. 5 and 6 show the two parts of the cartridge ejector, the cartridge extractor 4 and the extractor element 18, from which the cartridge ejector is preferably composed.
  • the cartridge extractor 4 has a cylindrical base body 22, which enables circular guides in the monoblock in the area of the current. With such a design, the cartridge extractor 4 for the upper and lower barrel 2, 3 can be the same.
  • the cartridge extractor 4 is secured against rotation by the extractor element 18, which is shown in section in FIG. 6, in which the structure on the right of the piece on the left of the rifle (mirror image) differs.
  • a damping element 28 in the form of an O-ring is attached to the cam 6 on the extractor element 18 in a bore, by means of which the impact of the control plate (edge 29 on the cam 6) is braked.
  • control pin 7 shows the interaction of the control pin 7 with the control flap 11. It can be seen in particular that the control of the cartridge extractor 4 by the control flap 11 is on the outside of the monoblock 1 and is therefore easily accessible. It can also be seen that the cartridge extractor 4 can be guided in a round bore 30 in the monoblock 1 without the monoblock 1 being weakened inadmissibly.
  • the ejector device according to the invention is shown in FIG. 8 with a further special feature.
  • One recognizes the cartridge extractor 4, the extractor element 18 and the control flap 11 driven by the control pin 7, which can be tilted about the axis 12, in this position the catch 17 against the cam 6 on the control flap 11 blocking the movement of the cartridge ejector (clamping position) .
  • a threaded bore 31 in the monoblock 1 there is an internal head screw 32 which can be screwed in so far that its tip extends into a bore 33 at the end 14 of the longer arm 13 of the control flap 11. This prevents the control flap 11 from tilting about the axis 12 through the control pin 7 into the clamping position.
  • Such a simple switch-off of the automatically operating cartridge ejection device is desirable, which, however, has not hitherto been possible with known rifles for reasons of space alone.
  • the mobility of the control device can also be changed.
  • the control pin 7 should be "stiff". Such a condition is difficult to meet or to maintain over a long period of time.
  • the stiffness can also be taken over by the control flap 11 as the element which transmits and reinforces the bolt movement.
  • the mobility is changed, for example, by the pressure of a spring 34, which can be pressed more or less strongly by the screw 32 onto the longer arm 13 of the control flap 11.
