Definitions

  • the invention relates to a fore-end repeater according to the preamble of claim 1.
  • the fore-end of the weapon ready to fire is always in the front end position, ie the end position facing away from the shooter. In this position, the shutter of the weapon is closed. The opening of the shutter, the ejection of the empty cartridge and the tensioning of the lock takes place by manual displacement of the forearm of the front end position in the shooter facing the rear end position. By the subsequent displacement of the forend into the front end position the barrel of the Vorderschaftrepetierers from the magazine for the subsequent shot certain cartridge is supplied and closed the shutter. The fore-end repeater is then ready to fire.
  • a major disadvantage of known forearm repeaters is therefore basically due to their typical construction handling. To close the shutter, the shooter must push the forend in the firing direction. However, for the firing immediately after pull on himself. The locking device prevents unwanted opening of the weapon. Such a movement is cumbersome, time-consuming and contrary to the natural disposition of the shooter.
  • the plurality of known fore-end repeaters have a repeating stroke of the same magnitude as the repeating stroke at the initial position between the housing and the fore-end.
  • part of the guide and the rods of the repeater are unprotected.
  • Known still repeaters are therefore quite susceptible to malfunction caused by, for example, the ingress of dirt. The shooter must therefore always ensure that the ingress of dirt is avoided. This is disadvantageous in particular with regard to the most comfortable handling possible of the percussion repeater.
  • the aim of the invention is to provide a fore-end repeater, which is safe to handle without a locking device and which has no Repetierhublücke in the fire-ready initial state.
  • the aim is also a weapon that is tailored to the ergonomics of the shooter and has a pleasing appearance in the closed or ready to fire state.
  • the invention provides that the closure device and the forend are coupled in such a manner, in that, when the forearm is displaced, the closure device can be actuated opposite to the displacement direction of the fore-end.
  • a cartridge is supplied to the barrel of the Vorderschaftrepetierers by shifting the forearm from the shooter facing away from the front end position in the shooter facing the rear end position of the barrel and closed the closure device.
  • the forward end position of the fore-end rather than the front end position, defines the ready-to-fire state of the fore-end repeater, in which the rear end of the forend is in abutment with the housing.
  • An unintentional displacement of the forearm by the guide hand is therefore excluded and has the further advantage that it can be dispensed with the necessary in known Vorderschaftrepetierern locking device.
  • the inventive lash adjuster in the ready-to-fire starting state no longer has a repositioning gap, ie a gap the size of the repetition stroke.
  • the fore-end repeater in contrast to the known fore-repeaters, is completely closed. The penetration of dirt into the interior of the weapon is therefore largely excluded. In contrast to known Vorderschaftrepetierern comfortable handling is also guaranteed. The shooter can safely put the gun ready to shoot even in polluted environments, without always having to worry about the dirt entering the weapon.
  • the closure and the forend are coupled to one another via a reversing gear, which in one specific embodiment is formed by a push rod connected to the forearm, an actuating rod connected to the closure device and at least one rotatably arranged one Gear which engages formed in the engagement of the gear portions of the push rod and the actuating rod.
  • a reversing gear which in one specific embodiment is formed by a push rod connected to the forearm, an actuating rod connected to the closure device and at least one rotatably arranged one Gear which engages formed in the engagement of the gear portions of the push rod and the actuating rod.
  • the operating rod connected to the closure device serves to actuate the closure head.
  • the gear which engages in the engagement of the gear formed portions of the push rod of the fore and the actuating rod the movement of the push rod connected to the forearm is converted into an opposite movement of the actuating rod.
  • the portions of the actuating rod and the push rod formed for the engagement of the gear are toothed or perforated.
  • they have in an alternative embodiment ladder-like recesses, which are preferably formed continuously, with this alternative embodiment can be realized inexpensively by means of a ladder-type stamped grid.
  • the gear is mounted on a housing-fixed axis.
  • Vorstepreperser the gear is rotatably mounted on a guide arranged along the run, on which a carriage is slidably mounted. At this the forearm and the push rod is fixed, so that a manual displacement of the forearm is converted directly into a displacement of the carriage on the guide arranged along the barrel and ultimately into a displacement of the push rod. This in turn is converted via the gear in an oppositely directed displacement of the actuating rod of the closure.
  • the closure device and the forend are or the like to realize the reversal of motion via an envelope drive, a belt drive, a belt transmission or the like.
  • coupled which may be formed in a specific embodiments as a cable drive, chain drive, belt drive or as a toothed belt drive, wherein the cable drive two rollers and a roller spanning the rope, the chain drive two sprockets and sprockets spanning the chain, the belt drive two discs and a belt spanning the pulleys and the toothed belt drive comprises two toothed pulleys and a toothed belt spanning the toothed pulleys.
  • the rollers, the sprockets, the discs or the toothed disks of the envelope drive are rotatably mounted on a guide arranged along the barrel, on which a carriage is slidably mounted, to which the fore-end is attached wherein the carriage is connected to one of the two strands of the envelope drive and an actuating rod connected to the closure with the other of the two strands.
  • a manual displacement of the fore-end is translated immediately into a displacement of the carriage on the guide arranged along the barrel, which in turn, due to the existing connection of the carriage with one of the two strands of the envelope drive in a rotation of the Rolls, the sprockets, the discs or the toothed disks of the Hülltriebes is implemented, which ultimately leads to an oppositely directed displacement of the connected to the other strand of the Hülltriebs actuating rod of the closure device.
  • the invention further provides that the reversing gear, the outer drive, the belt drive, the belt transmission or the like. a reduction or transmission gear is. As a result, the forearm and the closure head can travel different distances if necessary.
  • Vorderstate repeater has a barrel 11 and a shaft main part 13, the rear has a rifle piston 14 and the front side merges into a forearm 12. Between the shaft 13 and the piston 14, a pistol grip 15 is formed, which allows the comfortable operation of a trigger 16. The latter is embedded in the shaft main body 13 from below immediately before the pistol grip 15. He stands for the purpose of firing shot in a conventional manner with a (not shown) cock in Connection that actuates a (also not shown) firing pin.
  • the shaft main part 13 carries as a system housing in the axial direction of the bolt action rifle 10 forwardly extending barrel 11, the rear end 21 of a closure device 17 is closed. The latter has a closure head 18, which in the closed position of the weapon 10 with the rear end 21 of the barrel 11 is engageable.
  • the fore-end 12 is designed to be displaceable along the barrel 11.
  • the upper half of Fig. 1 shows the fore-end repeater 10 with the fore-end 12 in a rear end position and the closure device 17 in its front closed position.
  • the fore-end 12 is in its front end position, while the closure device 17 is open to the rear.
  • the movement of the forearm 12 from the front end position to the rear end position is thus converted into an opposite movement of the closure device 17 and the closure head 18, respectively.
  • the weapon 10 is closed and at the same time pulled into the shoulder.
  • the actuating rod 19 coupled to the push rod 20 via the gear 29 moves the closure device 17 immediately to the rear.
  • the closure head 18 moves to the rear; the weapon 10 is opened and ejected a fired cartridge.
  • the movement reversal formed according to the invention makes it possible to realize a fore-end repeater 10, in the ready-to-fire starting position of which the fore-end 12 is located in a rear, closed end position.
  • the fore-end repeater 10 no longer has a repeating stroke, as is the case in known backstops. An adverse penetration of dirt is therefore reliably avoided.
  • no locking device is necessary because the forearm 12 is already in its ready-shot starting position to stop the housing 13. Rather, the weapon 10 can be designed to be extremely slim, which leads to a pleasing and elegant appearance, for example, often important for hunting weapons.
  • Fig. 2 shows another embodiment of a Vorderschaftrepetierers 10 in a perspective view, wherein like components are provided with the same reference numerals.
  • a longitudinal recess 32 is laterally inserted in the housing 13. Through this, a fired cartridge case is ejected and a new cartridge 31 is loaded from a magazine 30. The latter can be inserted, for example, from below into the housing 13.
  • FIG. 3 shows the inner structure of the forearm repeater 10, which is otherwise concealed by the forearm 12. It can be seen that the forearm 12 of the fore-repeater 10 is in its rear end position, ie in the ready-to-fire starting position.
  • a guide 22 is mounted on which a carriage 23 is slidably received.
  • a disk 25 rotatably mounted (see also Fig. 5), which are both spanned by a belt 26, a chain or an endless belt.
  • the fore-end 12 is fixed to the carriage 23, which in turn is connected to one of the two strands (not visible in FIG. 3) of the enveloping drive formed by the two disks 25 and the belt 26.
  • FIG. 5 shows the forearm 12 in the front end position with open closure 17 and the actuating rod 19, which is inserted in the housing 13 compared to the position shown in Fig. 3.
  • the assembly consisting of the forearm 12, the push rod 20 and the slide 23 is subject to an inertial force which the entire assembly wishes to remain in relative to the recoil-conditioned, rear-running barrel-housing-closure assembly.
  • the force sprays generated thereby can be achieved by means of resilient components arranged in the force flow, such as e.g. Coil springs or damping elements are encountered.
  • FIGS. 4 and 5 also show that although the fore-end 12 is in the forward end position and the closure 17 is in the rearward end position, the effective guide length of the carriage 23, and thus that of the fore-end 12, is maintained. It is also advantageous that the present Hülltechnischkonstrutation has no direct contact with the barrel, which is imperative for good shot images.
  • FIG. 6 shows a further embodiment of a fore-end repeater 10 according to the invention with the forearm 12 in the rear end position.
  • the actuating rod 19 connected to the closure device 17 (see also FIGS. 7 and 8) and the push rod 20 connected to the forearm 12 via the carriage 23 are designed in the form of a ladder-type stamped grid which can be produced at low cost.
  • FIG. 7 and 8 show the embodiment of Fig. 6 with a fore-end 12 in a position between the rear and front end positions (see Fig. 7) and a fore-end 12 in Fig. 7, to illustrate the mechanism according to the invention front end position.
  • the closure 17 is only partially opened in FIG. 7 and completely opened in FIG.
  • the gear (29) for example, stepped (two-ply) be formed, wherein the gear stages have different numbers of teeth. If the actuating rod (19) with the first and the push rod (20) with the second gear stage engaged, the reversing gear forms a lower or transmission gear and the two rods (19, 20) set in the operation of the forearm (12) different distances back.
  • two gears (29) can be arranged parallel to each other. The important thing is that they are firmly linked.
  • FIGS. 2 to 8 are also suitable for the construction of a weapon according to the so-called bullpup design, because the awkward gripping of the forearm on the located near the shoulders Kammerstengel deleted.
  • Bullpup weapons are weapons in which the barrel has been moved farther back toward the buttstock in relation to other known weapons and the magazine 30 is in the rifle butt 14. This makes it possible to realize a very short compact weapon.
  • a short design of the weapon is also achieved if the trigger 16 is not firmly embedded in the shaft main body 13, but is integrated in the forearm 12.
  • the trigger 16 thus belongs to the fore-end assembly, which is moved relative to the barrel-housing-closure assembly and thus brought forward to open the weapon in the firing direction. This makes it possible to arrange the magazine 30 (with the weapon closed) directly above the trigger 16 or even behind it, which has a very favorable effect on the overall length of the weapon. If the weapon is open, you can remove the magazine unhindered down. The handling of the weapon is further improved.
  • Vorderstate repeater has a barrel 11 and a shaft main part 13, the rear has a rifle piston 14 and the front side merges into a forearm 12. Between the shaft 13 and the piston 14, a pistol grip 15 is formed, which allows the comfortable operation of one. The latter is embedded in the shaft main body 13 from below immediately before the pistol grip 15. He stands for the purpose of firing a shot in a manner known per se with a (not shown) cock in connection, which operates a (also not shown) firing pin.
  • the shaft main part 13 carries as a system housing in the axial direction of the bolt action rifle 10 forwardly extending barrel 11, the rear end 21 of a closure device 17 is closed. The latter has a closure head 18, which in the closed position of the weapon 10 with the rear end 21 of the barrel 11 is engageable.
  • FIGS. 2 to 8 can also be realized on shotguns with tube magazine, wherein the carriage is guided on the magazine tube longitudinally displaceable and rotationally fixed and carries the forearm 12.
  • the rotary elements of the envelope or the gear 29 are laterally mounted on the magazine tube rotatably.
  • the fore-end repeater 10 has a barrel 11, a shaft main part 12, a longitudinally displaceable forearm 12 and a closure device 17 coupled thereto, the latter being engageable with the rearward end 21 in the closed position of the repeater 10.
  • the closure device 17 and the front stock 12 are coupled in such a way that, when the forearm 12 is displaced, the closure device 17 can be actuated opposite to the direction of displacement of the forearm 12.
  • the fore-end repeater 10 can be handled safely without a locking device and has no repeating stroke in the ready-to-fire initial state.
  • a matched to the ergonomics of the shooter weapon is created, which has a pleasing appearance in the closed or ready to fire state
