DETAILED DESCRIPTION OF THE INVENTION

[0035] Depicted in FIG. 1 is a repeating rifle, denoted by 1, according to a first embodiment of the invention, the linear action of which (with a breechblock head located thereon in the firing direction) allows the operation as a straight-pull bolt action repeater. For this purpose, the breechblock, longitudinally guided in a housing 4 arranged between the forestock 2 and buttstock 3, is provided with a bolt handle 5, at the free end of which a handle ball is attached for comfortable repeating. A cartridge magazine 6 and a trigger assembly 7 are inserted in the housing 4, and a barrel 8 is arranged at the front end face of said housing.

[0036] The forestock 2 is passed through transversely to the barrel axis by an actuating handle 13, which is axially displaceable, is arranged in a rotationally-fixed manner, and is configured as a sliding switch 13, the two end faces of which are mirror-symmetrically opposite one another and are operable as push-buttons (with a left and a right end position). With these, the repeating rifle 1 can be switched between the two operating modes repeating by means of bolt handle and repeating by means of forestock.

[0037] In FIG. 2, the forestock 2 is removed, such that a longitudinal guide 9 becomes visible, said longitudinal guide being configured as a rectangular rod 9 in parallel to the barrel and being fixed to the housing 4 on the end face with a largely mirror-symmetrical slide 10 that is mounted on the longitudinal guide in an axially displaceable and rotationally-fixed manner. For this purpose, the slide 10 is provided with a preferably square longitudinal perforation 18. Perpendicular to said longitudinal perforation, the slide has a shaft-like transverse perforation 19 for longitudinally guiding the sliding switch in a rotationally-fixed manner. On its two side faces, the slide 10 is provided with mirror-symmetrical guide grooves 11 (or longitudinal perforations) for two actuating bars 12 (preferably of rectangular cross section), which are coupled to the linear breechblock in an axially-fixed manner. Alternatively, the at least one actuating bar 12 may be longitudinally guided only in the housing 4 or both in the housing 4 and in or on the slide 10.

[0038] The forestock 2 and the slide 10 form an assembly connected to one another in a mechanically rigid manner.

[0039] With the slide 10 removed, FIG. 3 shows the longitudinal guide 9 with a polygonal profile, as the aforementioned rectangular rod. It is preferably stationarily arranged as a cantilever on the housing 4 below the barrel 8 and substantially in parallel thereto (said barrel also being stationarily arranged on the housing 4). Since the slide-forestock-assembly 2, 10 is arranged on said cantilever (so as to be longitudinally movable) and is not in mechanical contact with the barrel 8, the cantilever can vibrate freely in a way that is conducive to shooting precision.

[0040] The straight-pull breechblock not depicted here is guided in the housing 4 so as to be longitudinally movable and is coupled, preferably in a positive-locking manner, to at least one of the two actuating bars 12 in an axially-fixed manner.

[0041] FIG. 3 to FIG. 6 disclose the compact and user-friendly switching mechanism, the sliding switch 13 of which comes into engagement either with the rectangular rod 9 (according to FIG. 4) or the actuating bar(s) 12 (according to FIG. 6) by said sliding switch being actuating in the manner of a push-button on its left or right end face. For this purpose, the latter 12 according to FIG. 5 is/are provided with at least one gap-like cut-out 14, and the rectangular rod 9 is provided with a vertical transverse groove 15.

[0042] In order to achieve a bolt-like positive engagement, the sliding switch 13 according to FIG. 5 is provided with a cuboidal locking projection 16, which on its side pointing away from the rectangular rod transitions into a groove-like locking set-back portion 17, which terminates with an end-face cross section in the outline of the locking projection 16.

[0043] On its side pointing toward the rectangular rod 9, the locking projection 16 is stepped. From here, the sliding switch 13 has a flat cross section, which according to FIG. 1 protrudes transversely out of the forestock 2 like a push-button. This shape of the sliding switch 13 provides in both its directions of movement locking noses 20, 21 on both sides of the locking projection 16, which serve to axially lock the slide 10 and thus the forestock 2 (see FIG. 5).

[0044] For the operating mode with the bolt handle 5 according to FIG. 1 to FIG. 3, according to FIG. 4 and FIG. 5 the groove-side locking nose 20 of the locking projection 16 comes into engagement with the vertical transverse groove 15 of the rectangular rod 9 and out of engagement with the gap-side portion 14 of the actuating bar(s) 12 with its opposite locking nose 21. The slide 10 with the forestock 2 attached thereto is thereby axially locked on its longitudinal guide 9 and the forestock 2 is thus fixed to the housing 4 in an axially-fixed manner. When actuating the bolt handle 5, the two actuating bars 12 slide unhindered in the guide grooves 11 of the slide 10 (or laterally past said slide 10) and thereby pass through the groove-like locking set-back portion(s) 17 according to FIG. 4 and FIG. 5.

[0045] After displacing the sliding switch 13 into the opposite end position by ergonomically comfortably pressing it from its end face projecting out of the forestock 2 (see FIG. 1), it is exactly the opposite: In this position of the sliding switch 13, according to FIG. 6, its groove-side locking nose 20 has now come out of engagement with the vertical transverse groove 15 of said locking nose 20 and its gap-side locking nose 21 has come into engagement (with the gap 14) with at least one of the two actuating bars 12. An axial connection of the slide 10 to the actuating bar(s) 12 is thus established in a positive-locking manner and is released from the rectangular rod 9. The firearm 1 can thus now be operated as a pump action repeater, the forestock 2 driving the linear breechblock (in the same direction) and the bolt handle 5 fixed thereto being moved uselessly back and forth therewith. This does not interfere mechanically and ergonomically, but it may be removed for aesthetic reasons.

[0046] FIG. 7 shows this operating mode with the breechblock closed with the slide 10 and FIG. 8 with the forestock 2 attached thereto in the front end position of said forestock 2. The market accepts the hand-wide gap that exists here between the forestock 2 and housing 4, even if it is concealed here and there with forestock extensions projecting to the rear in a U-shape. This is counteracted by the present invention in the operating mode with the bolt handle 5, which is presumably predominantly used: In FIG. 1 and FIG. 2, the slide 10 is located in its rear end position locked to the longitudinal guide 9 by the sliding switch 13, the forestock 2 transitioning flush into the housing 4 in a stylish manner.

[0047] The design of the sliding switch 13 with its latching noses 20, 21 on both sides, and the arrangement of the corresponding gap 14 or groove 15 arranged in alignment with said sliding switch 13, which gap 14 or groove 15 is arranged transversely to the barrel axis according to FIG. 5, allow for switching between the two described operating modes only when the breechblock is completely open. This switching logic has 3 advantages: [0048] 1. There is no cartridge in the barrel, so no unintentional shot can be fired when switching. [0049] 2. When the weapon 1 is loaded and possibly even ready to fire, the sliding switch 13 is automatically secured against displacement, so that the set operating mode cannot be changed unintentionally. [0050] 3. For the shooter, the two switching positions are clear, so that it is easy to learn and, after some practice, the weapon 1 can be intuitively controlled. To this end, it appears plausible to let the end face of the sliding switch 13 protrude on the side of the bolt handle in the operating mode with the bolt handle 5.

[0051] According to FIG. 5, the sliding switch 13, as mentioned, is stepped at the groove-side locking nose 20 and extends from here with its flat cross section up to its end face. This cross sectional profile allows for easy assembly with an open breechblock through the entire firearm 1. Here, the sliding switch 13 first passes a corresponding shaft in the forestock 2, then passes through the cross sectionally identical transverse perforation 19 of the slide 13, before it emerges with its end face out of the forestock 2 through a shaft of a small cross section. This end position is formed in a mechanically elegant manner by the groove-side locking nose 20 striking on the groove base of the vertical transverse groove 15 and thus ensures the maximum positive engagement between the longitudinal guide 9 and the sliding switch 13 and thus with the slide 10 and hence also on the forestock 2 fixed thereto.

[0052] In both end positions, the sliding switch 13 is secured in position by a spring catch and can be pushed out of the forestock 2 laterallyfor example with a screwdriver bladewhen the breechblock is open. The forestock-slide-assembly 2, 10 can then be removed in the firing direction, for example for cleaning the weapon.

[0053] As an alternative to the locking noses 20, 21, a round pin may be arranged on at least one of the two end faces of the locking projection 16, the axis of which round pin extends in the direction of movement of the sliding switch 13. The one engages into a corresponding transverse bore of the rectangular rod 9 and the other engages into a through-bore of the actuating bar(s) 12, which can be produced economically as a punched hole.

[0054] Nevertheless, at least one raised form that is arranged on the sheet metal strip(s) 12 and is economically producible by forming technology (e.g. bent sheet metal flap) can come into or out of positive-locking engagement with a corresponding recess of the locking projection 16.

[0055] In another embodiment, which is not graphically illustrated here, the sliding switch 13 described above is configured as an axially-fixed and rotatable switching shaft. It is rotatably mounted in an axially-fixed manner in a transverse bore, in a similar position as the transverse perforation 19, of the slide 10 and corresponds to recesses in the actuating bar(s) 12 and the rectangular rod 9, which recesses, when the breechblock is open, are congruent transverse to the barrel axis and are preferably of semi-circular cylindrical configuration, or of prismatic or V-shaped configuration. For this purpose, the lower side faces 22 of said bars 12 and the lower side face 23 of the rectangular rod 9 structurally form a plane in which (or in a plane parallel thereto) the axis of said switching shaft lies. The switching shaft is configured as a circular cylinder that can be manually rotated (from the outside by means of a rotary handle/rotary handles).

[0056] While the two half-shaft cross sections in the region of the actuating bars 12viewed axiallyare congruent, the half-shaft corresponding to the rectangular rod 9 is rotated by 180 compared to those two of the actuating bars 12. Thus, in the operating mode as a repeating rifle with the drive by way of the bolt handle 5, the switching shaft with its central half-shaft is in engagement with the rectangle 9 and out of engagement with the half-shaft pair of the actuating bar pair 12: The slide is thereby axially locked on its longitudinal guide 9 and thus the forestock 2 is locked to the housing 4 in an axially-fixed manner. Upon actuating the bolt handle 5, the two actuating bars 12 slide unhindered along the guide grooves 11 of the slide 10 and past their half-shaft cross sections.

[0057] After rotating the switching shaft by 180, it is exactly the opposite: In this angular position, the switching shaft is now in engagement with the two actuating bars 12 and is decoupled from the rectangular rod 9: An axial connection of the slide 10 to the actuating bars 12 is thus established in a positive-locking manner and is released from the rectangular rod 9. The firearm 1 can thus now be operated as a pump action repeater, the forestock 2 driving the linear breechblock (in the same direction) and here, too, the bolt handle fixed thereto being moved uselessly back and forth therewith.

[0058] The described design of the switching shaft, as well as the positions of the corresponding rectangular and actuating rod/bar(s) 9, 12 allow switching between the two described operating modes described only when the breechblock is completely open. This has the same 3 advantages as mentioned above: [0059] 1. There is no cartridge in the barrel, so no unintentional shot can be fired when switching. [0060] 2. When the weapon 1 is loaded and possibly even ready to fire, the switching shaft 13 is automatically secured against rotation, so that the set operating mode cannot be changed unintentionally. [0061] 3. For the shooter, the two switching positions are clear, so that it is easy to learn and, after some practice, the weapon 1 can be intuitively controlled.

[0062] In a second embodiment of the invention according to FIG. 9 and FIG. 10, the sliding switch 13 or the switching shaft or a pivot mechanism are arranged within the weapon, such that they are not visible from the outside and cannot be operated incorrectly, and after removing the cartridge magazine 6, for example, can be manually switched through the then free magazine well.

[0063] In the case of the pivot mechanism configured in this manner, according to FIG. 9, a mirror-symmetrical and fork-shaped pivot latch 24 (which can be considered a pendulum switch 13 and can be produced economically as a punched bent part), is guided with its two latch flanks 26 on bearing pins 28 arranged on the slide 10 on both sides, also mirror-symmetrically, so as to be pivotable about the pin axis transverse to the repeating rifle 1. For this purpose, the two flanks 26 are provided with two coaxial bearing bores 29.

[0064] At their free end, each of the two flanks 26 has a respective gap 33, 34 on both sides in the circumferential direction, wherein the one can come into or out of engagement with, e.g., a sheet metal flap 35 of the actuating bars(s) 12 and the other one with a projection or a recess of the buttstock-housing-barrel-longitudinal guide-assembly 3, 4, 8, 9. For this purpose, FIG. 9 shows a locking bolt 30 projecting transversely out of the rectangular rod 9 mirror-symmetrically on both sides, the two ends of which are laterally in engagement with the two gaps 33 of the pivot latch 24, wherein it is structurally preferable if the rear flanks of the gaps 33 abut against the rear outer surfaces of the locking bolts 30 and the slide 10 (including the forestock 2) preferably strikes against the housing 4 in the firing direction. The slide 10, preferably configured as a rectangular tube, is thereby connected to the buttstock-housing-barrel-rectangular rod-assembly 3, 4, 8, 9 in an axially-fixed manner and thus also the forestock 2 that is stationarily attached thereto or optionally formed in one piece therewith. This results in the operating mode by means of the bolt handle 5. During its repeating operation, both actuating bars 12, which are axially coupled to the breechblock in a mirror-symmetrical mannerof which actuating bars 12 only the left one is shown so that the pivot latch 24 becomes visibleoscillate through their shafts 32. The sheet metal flaps 35 bent inwardly in a mirror-symmetrical manner out of the two actuating bars 12 (and out of their bottom sides 22 by forming technology) hereby pass the bottom sides of both latch flanks 26 in an unhindered manner.

[0065] When the breechblock is open, the two ends of the locking bolt 30, which can be produced as welding bolts (bolt welded symmetrically on the rectangular rod 9), are mirror-symmetrically opposite one another with their two corresponding gaps 33 and the two sheet metal flaps 35 with their two corresponding gaps 34 in the latch flanks 26. In this position, the pivot latch 24 operable as a pendulum switch 13 can be used to switch between both operating modes in a manual and toolless manner. For this purpose, an operating finger engages through the open magazine well 31 according to FIG. 9 and engages under a handling lip 25, which is arranged on a latch bridge 27 connecting both latch flanks 26. By pressing a finger on the bottom side of the handling lip 25, the pendulum switch 13 jumps from its angular position in FIG. 9 into its other end position according to FIG. 10. Thus, the two gaps 33 in engagement with the two locking bolt ends 30 in FIG. 9 synchronously come out of engagement and the gaps 34, according to FIG. 10, synchronously enter into a positive engagement (in the direction of the direction of movement of the slide 10) with the two mirror-symmetrical sheet metal flaps 35 of the two actuating bars 12. This results in the operating mode as a pump action repeater with the following flow of force: forestock 2.fwdarw.slide 10.fwdarw.bearing pin 28.fwdarw.bearing bores 29.fwdarw.latch flanks 26.fwdarw.gaps 34.fwdarw.sheet metal flaps 35.fwdarw.actuating bars 12.fwdarw.breechblock.

[0066] To switch to the previous operating mode with the bolt handle 5, when the breechblock is open and the cartridge magazine 6 is removed, the pivot latch 24 must be pressed back into its original end position through the magazine well 31 by pressing a finger on the latch bridge 27, in which end position the two gaps 33 of the two flanks 26 again synchronously engage around the two locking bolt ends 30.

[0067] The pivot latch 24 snaps in a haptically perceptible manner into both end positions, in which it remains securely. This is achieved by a catch, which consists of at least one catch pin 38 arranged transversely on the slide 10, on the outside face of which catch pin 38 a ball rests that is acted upon by a catch compression spring 37. All catch elements are arranged in a respective, preferably congruent, perforation 36 of the latch flanks 26, which is covered inwards by the slide 10 and outwards by the respective actuating rod 12. Thus, they are enclosed securely in a sandwich-like manner in the latch flank(s) 26 between the actuating bar(s) and the side face(s) of the slide 10.

[0068] The pendulum switch 24 is to be understood mechanically as a single-arm lever with a pivot axis about the axis of its bearing pins 28. To operate it, the latch bridge 27 must be pressed or the handling lip 25 must be pulled (up). It may be economically advantageous if the switch 13, 24 is operable only by pressure. To achieve this, the pendulum switch must become a rocker switch 13. This is achieved by extending at least one latch flank 26 in the firing direction, whereby a two-armed lever would be created, the two ends of which could be operated by manual pressure through the forestock 2.

[0069] Another type of construction not graphically illustrated here comprises a pivot mechanism, also arranged on the slide 10, the axis of rotation of which extends substantially in parallel to the barrel axis and which is rotatably mounted on the slide 10 or forestock 2 in an axially-fixed manner. The end of the pivot mechanism accessible through the magazine well has a claw coupling configured as a rocker switch, which claw coupling in its one angular end position comes into or out of engagement with the housing-barrel-longitudinal guide-assembly 4, 8, 9 and in its other angular end position with the breechblock-actuating bar(s)-assembly 12.

[0070] The embodiments described above can be continued in a variety of variants. In order to fulfill the goal of the invention, all have in common the mechanical function that on the buttstock-housing-barrel-longitudinal guide-assembly 3, 4, 8, 9 both the forestock-slide-assembly 2, 10 and the breechblock-actuating bar(s)-assembly 12 are guided substantially in parallel to the barrel axis and independently of one another, wherein, in accordance with the invention, the first is coupleable to the second assembly in a toolless manner, such that the third assembly is then repeatable by means of the bolt handle 5, or the second is coupleable to the third assembly in a toolless manner, such that the repeating firearm 1 is repeated by means of the forestock 2.

[0071] In another embodiment, which is also not graphically illustrated here, the forestock 2 is decoupled from the slide 10 and is guided separately on the longitudinal guide 9 in an axially movable manner. Both elements are force-coupled by way of a reversing gear, so that they move axially in opposite directions. This design takes aesthetic aspects into account in the operating mode as a pump action repeater, since when the breechblock is closedi.e. when the weapon is ready to firethe forestock 2 transitions flush and seamlessly into the housing 4.

[0072] Another embodiment, also not graphically illustrated, comprises the so-called bullpup design. This is a short design of firearms, in which the classic buttstock 2 is omitted and the housing 4 replaces it with an ergonomically designed shoulder system. The subject matter of the invention is predestined for this short design, since the repetitionby means of the forestock 2 or bolt handle 5is carried out ergonomically comfortably in the front region of the weapon 1 using the actuating bar(s) 12, while the actuating bar(s) 12 ensure the other weapon functionse.g. loading by means of the movement of the breechblock and tensioning the lockin the housing 4 in the manner of transfer rails.

[0073] All features and advantages arising from the claims, description and drawings, including structural details, arrangements and method sequences, may be relevant to the invention both in themselves and in a variety of combinations.
