Definitions

  • the invention relates to a hunting or sports weapon with an interchangeable barrel, a barrel and a breech housing.
  • Hunting or sporting weapons are known which accommodate an interchangeable barrel. This makes it possible to adapt the same weapon to different calibers or to shorten the weapon for transport purposes.
  • the invention aims at a weapon that is as short as possible, without thereby reducing the intended use of the weapon, be it that the accuracy or accuracy decreases or the weapon has to be re-shot in each case by mounting or re-assembly, or that the interchangeability of the barrel the stability of the weapon is reduced.
  • the invention is based on a weapon of the type described in the introduction and proposes that the barrel be held only on the breech housing, which connects the barrel and the fore-end separated therefrom.
  • the invention connects the barrel only with the breech housing avoids disadvantages of the long shaft, which is otherwise customary for mounting the barrel.
  • a shaft is a relatively unstable structure that is easily deformed under load and also deforms without load, for example when the humidity changes. If these deformations are transferred to the barrel, the accuracy drops considerably.
  • the breech housing in turn provides a good attachment option for the barrel. Any forces acting on the barrel in connection with the attachment do not lead to deformation of the barrel.
  • the breech housing has a groove in which the barrel engages with an adapted shoulder, and that a screw clamps the barrel with the shoulder perpendicular to the barrel axis on the groove bottom.
  • the groove and the shoulder are formed by turning, ie if they represent parts of a rotating body, for example with the barrel axis as the axis of rotation.
  • Such grooves or approaches are easy to manufacture in this way with high accuracy.
  • the fastening screw itself only has to transmit holding forces. Forces in use are usually absorbed by the groove and the shoulder.
  • the invention proposes that the closure designed as a cylinder closure is movable together with the upper parts of the closure housing on guide strips which are fastened to the upper part of the closure housing. This ensures that despite the need for axial movement of the breech or the associated breech housing parts, which are required for ejecting the cartridge and reloading, the overall length of the weapon is not increased.
  • the relatively long guide strips are in the locked state of the weapon next to the rear part of the barrel or between the barrel and the adjacent shaft parts.
  • a stop made of plastic on the closure housing limits the path of the movable upper parts of the closure housing.
  • a stop is, in particular, immovable and consists of plastic.
  • the immovable design facilitates the use of plastic for this part, which in turn has the advantage that there is little noise when the attack takes effect.
  • the invention proposes that the stop cooperates with a locking lug, which is located at a suitable height on the stop, and that the lock of the cylinder lock can be disengaged after loosening an anti-rotation device .
  • the proposal according to the invention can advantageously be used when it is a repeating weapon in which the breech housing is designed as a magazine.
  • the sturdy breech housing that holds the magazine provides good fastening options for the interchangeable barrel and also for the shaft. It is recommended that the magazine has an interchangeable insert so that different ammunition always provides good guidance for the ammunition that is fed into the magazine. This reduces the risk of repetition problems.
  • Fig. 1 only the rear part of the barrel 1 is shown, which is essentially formed by the sleeve 21, in which the barrel part 22 is inserted with the cartridge chamber.
  • This sleeve 21 is shown in detail in Figs. 2-6.
  • the sleeve has an extension 6 on the underside, which is placed on a somewhat thickened part 23 a.
  • the outside contour of the approach 6 is obtained by a turning process.
  • a screw hole 24 is provided, in which the screw 7 (Fig. 1) engages.
  • the sleeve 21 also has at the rear end the locking lo, which consists essentially of three staggered projections 25. Areas 26 for the locking projections of the cylinder lock remain between the individual projections 25.
  • the locking takes place in that the locking lugs of the closure are pushed through the regions 26 and the closure is then correspondingly rotated.
  • the screw 7 holds the barrel inserted into the groove 5 in the lock housing 2.
  • This closure housing is designed in its main part as a magazine 18, which receives the magazine insert 19.
  • the front end 27 of the magazine insert 19 is held by the barrel 1.
  • the magazine insert receives the cartridges, of which the cartridge 28 is shown in FIG. 1.
  • the magazine insert has a suitable shoulder system for the cartridges 28 on the outside for some contours 29 for a secure hold in the magazine and inside.
  • the breech housing also carries those elements which connect the trigger 30 to the lock parts arranged in the upper part 12 of the breech housing 2. However, these parts are not shown in detail. Only the hook part 31 is shown, which interacts with the lock part 32 in the upper part 12.
  • the upper part 12 of the closure housing encloses or receives the essential parts of the closure.
  • the closure 9 is designed as a cylinder closure and carries, as is known per se, a plurality of warts 33 and 17 which cooperate with the projections 25 at its front end.
  • the plate 14 covers the upper part of the closure housing from below or holds these closure elements in part 12.
  • the closure On the lever 34 (FIG. 7), which is attached to the closure 9, the closure can be opened by turning and the opened closure can be withdrawn.
  • the upper part 12 of the closure housing slides on the guide strips, the cross-sectional configuration of which can be seen in FIG. 8.
  • Two guide strips are provided, the U-shape of which faces one another.
  • the guide strips are supported on the underside by rolling elements 15; of which one pair of rolling elements is mounted in the closure housing in the region of the front end of the magazine insert 19, while the other pair of rolling elements is arranged behind the rear wall of the magazine .18.
  • the rolling elements are not shown in FIG. 1.
  • the U-shape of the guide strips 13 allows the arrangement of guide bodies 35, for example are held by screws 36 in the closure housing.
  • These guide bodies can be made of plastic, in particular in the front area, in order to improve the sliding property and to reduce noise.
  • the use of metallic guide bodies is recommended in the rear area of the breech housing.
  • the underlying locking lug 17 comes to rest against the stop 16, which prevents inadvertent separation of the upper part 12 of the breech housing from the rest of the breech housing 2 or from the weapon. In this fully open position, the shot cartridge is ejected and a new cartridge is pushed out of the magazine insert.
  • the known anti-rotation device can be released in the open state against unintentional rotation of the cylinder breech, for example by pushing in the corresponding pin 37 or actuating a suitable device. As a result, the locking lug 17 can be rotated so far that it except. Engagement with the stop 16 comes.
  • the shaft 3 is attached to the breech housing 2, and the fore-end 4 is at least essentially carried by the breech housing 2.
