Abstract

The invention relates to a modular system for assembling different types of air guns, each air gun comprising: a first assembly comprising at least one barrel (10), a front piece (13) as a second assembly, a third assembly comprising at least one cylinder with a piston and a compression spring, and a gun stock. In each case, an identical second assembly which has the front piece (13) can selectively be releasably connected to different first assemblies comprising barrels with different respective calibers and/or to different third assemblies comprising cylinders which generate different muzzle energies. The invention is advantageous in that a manufacturer can now produce a larger number of different air gun types with defined properties using substantially fewer components. For example, if air guns are to be produced which comprise barrels with different respective calibers, the same front piece (13) can be used for this purpose.

Description

air rifle

The present invention relates to a modular system for the assembly of air guns of different types, each air rifle each comprising: a first assembly comprising at least one barrel, a front piece as a second assembly, a third assembly comprising at least one cylinder with piston and compression spring, and a rifle stock.

Air rifles are known from the prior art, which have a Kipplauf or buckling, which serves to tension by tilting the barrel when loading the air rifle, the compression spring of the piston of a Luftdruckkompressionskammer. DE 101 50 645 B4 describes an air rifle with a so-called suspension device for the dump, at the top of which there is also a housing on which the rear sight of the air rifle can be secured. The barrel is attached to this suspension device, which is formed as a box-shaped barrel suspension, by a molding process such as example by injection so that there is a one-piece connection between the barrel and the suspension device. The rear portion of the barrel is thus formed in the suspension device, so that a replacement of the barrel is not possible, please include. In this air rifle, the suspension device consists of a plastic material with fillers. In other conventional air rifles, the suspension device may also be made of metal (steel) and the run is just inextricably linked during manufacture with the suspension device to a one-piece component, usually by compression.

In the air rifle known from DE 101 50 645 B4 a fork is still seen easily, which is also integral with the front end of the air pressure chamber and thus un detachably connected. In this fork, the barrel is held in its closed position. Thus, such a conventional air rifle after assembly comprises an integrally formed component, which comprises the barrel and the suspension device and another integrally formed component which the fork and the air pressure chamber includes. A use of a single suspension for different runs with un ferent calibers or dimensions is also provided or technically feasible as the use of a single suspension for different air pressure chambers or other components that allow different Geschos generate senergies. This means that all components of an air rifle bestimm¬ a building type are each matched to each other and in the manufacture of air rifle partly inextricably linked, so that it is not possible for the manufacturer, for example, using a reduced number of components several Lufge weirs of different types manufacture.

Object of the present invention is to provide a modular system for the assembly of air rifles of the type mentioned, which allows a more flexible and cost-effective production of different types of air guns using a reduced number of components / assemblies.

The solution to this problem provides a modular system for the assembly of air rifles of the aforementioned type with the features of claim 1.

According to the invention, it is provided that a respective identical, the front piece aufwei send second assembly, optionally with each different first assemblies encompass runs each having different caliber and / or each with different third assemblies with cylinders that produce different projectile energies, is detachably connectable.

An advantage of the solution according to the invention that a manufacturer can now manufacture wesent Lich fewer components a larger number of different types with defined egg properties. For example, if air rifles produced with runs who, which each have different caliber, the same front piece can be used to. Alternatively, you can, for example, at the Monta ge the same front piece with different components connect the manufacturer, which include the cylinder and the air pressure chamber, making it possible, for example, to assemble with the same front piece different air rifles, in which the cylinder assembly generates different projectile energies ,

As regards its function, the second subassembly referred to in the context of the present invention corresponds in part to that component which is referred to in the cited prior art as a suspension device, since at the second assembly of the barrel of the weapon is attached. Here is the "front piece" with mounted weapon between the barrel or the first assembly and the cylinder and the air pressure chamber comprehensive third assembly.

The inventive solution is thus achieved that can be a number of air rifles of different types and build with different properties by means of egg ner reduced number of modules. The second subassembly referred to herein as a front piece is designed such that it can be combined with different runs and / or combined with different cylinders (air pressure chambers). To realize this technically, it is preferred that each identi cal, the front piece having second assembly, optionally with each nen different first assemblies comprising runs of different lengths releasably bond bar is. The respective first assembly comprising the barrel is thus compatible with the first assembly comprising the front piece, irrespective of the caliber and / or the length of the barrel. Thus, for example, with only one front piece Lufge weights with optionally produce a larger number of different runs.

According to a preferred embodiment of the invention, it is provided that the second sub-assembly before having having different first assemblies, each comprising a barrel, can be screwed. It is in the air rifle according to the present invention is preferably one which has a bend run / Kipplauf whose break point is between the rear end of the front piece and the front end of the third module, wherein a locking slide in a back open longitudinal bore of the front piece is received and is acted upon by its inner end face by a compression spring.

In the aforementioned variant of the invention, it is preferably such that a Verriege ment wedge is provided, which piece with an edge at the rear lower end of the front piece and recorded in the longitudinal bore of the front piece Verriege lungsschieber cooperates, wherein the relative height position of the locking wedge with respect to the locking slide is variably adjustable. By this measure, the coaxiality of the barrel and the rear of the air rifle with the third construction group (compressed air system) can be set repeatable and permanently fixed. When assembling articulated rifles, it is very important that the longitudinal axis of the barrel is aligned with the longitudinal axis of the compressed air system. In this case, it is particularly advantageous if the various respective first assemblies in the region of the barrel, which is screwed to the second assembly having the front piece, each have the same standardized thread. This solution not only reduces the number of assemblies needed to manufacture different air rifles, but also substantially reduces the risk of misassembly. In addition, it is (possibly at the manufacturer) possibly also possible, please replace the barrel after assembly by unscrewing the first assembly with the barrel of the front piece and then unscrew a first assembly with another run on the front piece.

According to a preferred embodiment of the invention, the front piece has de second assembly pushed onto the rear end of the barrel and recorded in a Boh tion of the Vorderstücks mother, the so-called barrel nut is to determine the front piece on the barrel on the rear end of the barrel the first assembly can be screwed on. The connection of front piece and barrel assembly can thus be done in a relatively simple assembly process by pushing the front piece over the rear end of the barrel and then unscrew the nut on the external thread at the rear end of the barrel. In this case, an elongated lower-side cutout is preferably provided in the rear region of the barrel, which serves to prevent rotation of the barrel during assembly and when tightening the barrel mounting nut.

A preferred embodiment of the invention provides that one with a sleeve ver provided grain base (or grain base) postpone to the front end of the barrel and set by means of a screw on a thread of the barrel at the front end muzzle nut on the barrel. This allows the grain, i. the front sighting unit of the weapon are mounted on the one hand in a simple manner on the barrel of the weapon and you have the opportunity to then put on said grain lower part optionally functionally under different grain or visor components. It is preferred in the front Endbe rich of the barrel a cutout, preferably on the underside of the barrel, mounted, which serves to receive a mounted on the grain base nose.

Preferably, different Visiereinrich lines are thus mounted on the said grain basis, selected from the group comprising a grain attachment and under differently configured components of a sighting group. This has the advantage that you can always use the same grain for different gun variant always the same run and for different grain and sighting during production. According to a preferred embodiment of the invention, a silencer on a Ge thread at the front end of the barrel can be screwed, on which optionally also an end nut is screwed. The provided at the front end of the barrel Au ßengewinde can be used in this solution variant to assemble in the production under different variants of the weapon, where each of the same run Verwen training finds.

According to a further preferred embodiment of the invention, a substantially elongated, preferably hollow cylindrical-shaped barrel weight pushed onto the front En de the barrel and screwed onto a thread at the front end of the barrel. Thus, in this variant of the invention can again be assumed during assembly of the same basic type of the barrel on which in this case the barrel weight is attached. Unlike conventional models, it is not necessary to use another barrel of higher weight. Since it is possible to unscrew weights of different sizes, the weight of the barrel can thus be varied over a wide range without the manufacturer having to make another run.

A further preferred embodiment provides that muffler and Laufge weight in their outer contours are aligned with each other and the muffler seen in the weft direction before the running weight on the barrel can be mounted. When using a basic type of run on the part of the manufacturer, it is thus also possible to attach both a barrel weight and a silencer to the barrel of the weapon.

A preferred embodiment of the invention provides that on the front piece a Vi sier and / or a rear sight is mountable. Again, it is also advantageous that you can assemble various other components on the same front piece, so that you can, for example, as needed in the production of the weapon the same front piece with a sight or a sighting device provided in different construction variants. Such a conversion of the weapon thus requires no replacement of Vorderstücks or even the purchase of another weapon. Here, the increased flexibility is particularly evident on the part of the manufacturer, which must provide fewer components to manufacture a number of different types of air guns.

Another preferred embodiment of the invention provides that the front assembly having the second assembly, each with different third components, each comprising a cylinder, can be screwed. In this advantageous variant, it is thus possible, for example, on the one hand to screw the first assembly comprising the barrel to the predecessor region of the front piece and, on the other hand, to embrace the cylinder bolt the third assembly to the rear of the front piece. This made light easy and quick installation and also makes it possible to produce by means of only one front piece a considerable number of different variants of air rifles.

According to a preferred embodiment of the invention it is provided that the Zylin having the third assembly also includes the trigger. In this assembly, the lock of the air rifle and all essential components for the initiation of the shot can be located. For example, in turn cylinder with air pressure chambers can be used for this third assembly, in which a different Fe derkraft and thus a different projectile energy is generated. Different projectile energies can alternatively be generated via the respective drive type for the trigger mechanism. For example, it is possible to use a conventional spring as a drive variant and to use a gas pressure spring (N-TEC) as an alternative drive variant and make both variants compatible. In all variants, it is advantageous that the assembly comprising the cylinder in the region in which the connec tion is made to the front piece, each formed uniformly, for example, with a standard each identically dimensioned thread, so that the respective Vari anten third assembly can always screw with a uniformly shaped front piece.

According to a preferred embodiment of the invention, for example, an adapter may be provided for the trigger, by means of which an actuatable via a coil spring trigger can be converted to an actuatable via a gas pressure piston trigger. In this variant of the invention te can use a substantially uniform design deduction for ver different weapon types, which then converts as needed via an adapter in another drive variant. Again, this results in a reduction of the manufacturer required components for weapons with different Abzugsmecha mechanisms.

Reference is first made to Figures 1 to 3, wherein Figure 1 shows a side view of the pure run 10 without further modules. The barrel 10 has at its front end an external thread 10 a. Figure 1 a shows a sectional view of the barrel 10, in which one can recognize the gradations in the rear and the trains inside the barrel.

Figure 2 shows the barrel of Figure 1, in which on the external thread 10 a at the front end a nut (nut 1 1), which has an internal thread was screwed. This mouth nut 1 1 may have a knurling on the outside, so you can screw it einfa cher. At the rear end of the barrel also has an external thread 10 b. On this external thread 10 b at the rear end can also be a nut 12 are screwed with internal thread, as shown in Figure 3. This nut 12 is used to attach the barrel 10 on the front piece and is also characterized as a barrel nut be distinguished.

In Figure 4 it can be seen how this nut 12, the front piece 13 is connected to the rear end of the barrel, wherein in the front piece 13 has a bore with a paragraph (see sectional view of Figure 4 a) and the front piece 13 on the Hinte re running can postpone and then set by screwing the nut 12, which is received by the bore of the front piece 13, the front piece 13 at the rear end of the barrel 10. The attached at the rear end of the barrel 10 in this Wei se front piece is shown in the view of Figure 4. The front piece is thereby as shown in Figure 4 a partially pushed into a receptacle of the front piece 13 through and present at the rear end of the barrel 10 optionally multi-stepped paragraphs results in a stop of the barrel in the front piece, so that when donning the barrel mounting nut 12 provides a secure frictional Ver connection between barrel and front piece.

Figure 4 b shows an enlarged detail of a detail of the sectional view of Figure 4 a, in which you can see the seat of the barrel mounting nut 12 in the bore in the rear ren region of the front piece 13 even better.

In the following, reference is made to FIGS. 5 to 9 and on the basis of these views the assembly of various alternatively attachable sighting groups on the barrel is explained in greater detail. The grain bottom part 15 shown in FIG. 5 has a sleeve 151 formed on the bottom, which can be pushed over the front end of the barrel 10. Subsequently, the grain base 15 can be set on the front on the barrel screwed running nut 1 1 who the. Figure 9 shows a mounted on the barrel in the front area sighting with grain tunnel 18 and in front of the sleeve of the grain base 15 on the barrel 10 screwed barrel nut 1 first

Figure 6 illustrates a first possible variant for the design of a sighting, in which an open Kornaufsatz 16 is attached to the grain base 15 from above. For example, by a screw connection of the grain attachment 16 may be connected to the Kornun terteil 15. The grain of grain base 15 and grain attachment 16 is here a mechanical variant, wherein an adjustment in height can be provided. Here, therefore, a sighting group with a classical grain of two superimposed positio- nierten components 15 and 16 constructed and the attachment to the barrel via the mounted on the grain base 15 sleeve 151th

As an alternative to the variant shown in FIG. 6, according to the invention there are various other variants of sighting groups, each of which can be fastened on the above-described Kornun terteil 15, for example, one can attach a fiber optic 17 on the grain base 15, as shown in FIG is shown. Here the advantage of the here also modular construction of the air rifle becomes clear. Characterized in that one uses in each case the same grain lower part 15, which in turn is detachably attachable to a ge in Figure 1 showed basic variant of a run 10 is fastened, reduces the number of different manufacturers for ver different firearms components. FIG. 8 shows a further alternative variant of a sighting group in which a grain tunnel 18, which as a rule has a ring grain, can be fastened on the grain base 15 described above. In Figure 9, a sighting group with a ring core 18 is again shown, which is mounted at the front end on the barrel 10, wherein the running nut 1 1 is shown, which is screwed in front of the grain base 15 on the barrel 10 to festzule the sighting group ,

Hereinafter, reference is made to Figures 10 to 14. In Figure 10, the barrel 10 is shown with a sight mounted on the barrel, you can see the sleeve of Kornun terteils 15, in which case in addition to the front of the barrel a muffler 19 is screwed. The screwing of the muffler 19 can be carried out in a simple manner by unscrewing the muffler 19 on the external thread 10 a at the front end of the barrel at the front end of the barrel at the forward end of the barrel 1 1 (see Figure 2), the one on the external thread 10th a of the barrel 10 has matching internal thread. Here again the advantage of the modular design becomes clear. The fact that the front of the barrel has a standardized thread, it is not necessary for the manufacturer to change the basic component of the pure run, as shown in Figure 1, when a weapon with silencer is to be made. The customer can purchase the silencer as an additional component ben and install it on the barrel of the weapon or this assembly is made by the manufacturer. With comparatively few basic components, one can produce a comparatively large number of different variants of the firearm.

In Figure 1 1, a barrel weight 20 is shown. The barrel weight 20 can be pushed onto the barrel from the front. The running weight comprises in principle a tube 20, a mouth cap 21 at the front end and a running cone 23 at the rear end. In FIG. 12, the running weight 20 is shown as it is pushed onto the barrel 10 and placed thereon on the barrel 10. Rich the mouth cap 21 is screwed tight. The barrel weight 20 is pushed with its hinte ren end practically as far over the barrel 10 that the mouth cap 21 on the thread 10 a (see Figure 1) can be screwed at the front end of the barrel 10.

FIG. 11 a shows various variants of silencers 19 which can be attached to the barrel 10 in the front region. For this purpose, the muffler 19 practically consists of a tube which has two internal threads, once at the front and once at the rear end. At the rear end, a cone 19a may be screwed to the tube of the muffler 19 so as to provide an optical transition to the barrel 10 somewhat reduced in diameter compared to the muffler (see for example Figure 13). At the front end you can screw a nut 19 c in the internal thread of the tube 19 a. Figure 1 1 a shows below a variant in which one screws a diameter corresponding to the muffler 19 nut 19 d instead of the cone 19 a in the rear In nengewinde the tube 19, which takes place, for example, if in addition to the muffler 19 yet a barrel weight 20 is mounted on the barrel.

FIG. 13 shows such a variant in which the running weight 20 is mounted on the barrel 10 in addition to a sound absorber 19 in such a way that then the silencer

19 sits in the axial direction in front of the barrel weight on the barrel, the attachment in the components in turn can be done by screwing the nut 19 d of the muffler on the aforementioned external thread 10 a of the barrel.

In Figure 14, an overall view is again shown, in which both the muffler 19, the barrel weight 20 and at the rear end of the front piece 13 on the barrel 10 are introduced. The barrel 10 with muffler 19, barrel weight 20, optionally alternatively a sighting group with grain forms the run group or first assembly according to the definition of the present invention, while the front piece 13 the second assembly 13 bil det, as shown in Figures 4 and 14 sees during assembly of the air rifle with the rear end of the first assembly (run group) is connectable.

In Figure 14 a are again different possible variants and combinations shown by way of example, wherein in the upper view, a muffler 19 and a sighting group 17 are mounted on the barrel 10, in the middle view, a barrel weight 20 on the barrel 10 mounted on it and in the bottom view a combination of muffler 19 and barrel weight

20 is mounted on the barrel. In Figure 15, the combination of the first assembly with the barrel 10 with the second assembly with the front piece and the clamping lever 24 is shown, by means of which the compressed air piston 25 is tensioned during loading of the rifle, wherein the clamping lever 24 at the bottom of the rifle below Barrel and front piece runs. It is in the air rifle according to the invention to such a Kipplauf or Knicklauf, which is opened by kinking of the barrel, then with the projectile (in air rifles usually a diabolo) is loaded, which is tensioned when opening the buckling of the compressed air piston. On the front piece 13, for example, a rear sight 42 can be mounted.

Further details regarding the connection between the barrel 10 and the front piece 13 egg nerseits and the cylinder assembly on the other hand emerge from the detailed sectional view of Figures 16 a and 16 b, to which reference is made below. The cylinder assembly comprises an air piston 25 and a pneumatic cylinder 26, which in its front region has a compressed air channel 27 which connects axially to the rear end of the inner bore of the barrel. The break point of the Kipplaufs is located between the rear end of the front piece 13 and the front end of the air cylinder 26. The clamping lever 24 includes a front lever 24 a, which pivots about the axis of the joint 29 when kinking of the barrel and the front end ge articulated on the front piece 13 is attached. About the hinge 29, the rear end of the front lever 24a is pivotally connected to the rear lever 24 b of the clamping lever. At its front end, the front lever 24 a is connected via a hinge 41 with the front piece 13. The projectile is inserted into the rear end of the inner bore of the barrel 10 and when firing the rifle from the compressed air, which passes through the compressed air channel 27 into the barrel bore, acted upon and accelerated. On the compressed air cylinder 26, a mounting rail 40 can be mounted on the upper side.

The compressed air piston 25 is guided displaceably in the compressed air cylinder 26. Druckluftkol ben 25 and compressed air cylinder 26 are components of the third assembly 27, namely the cylinder assembly to which the trigger mechanism 28 be found in the rear section. In Figure 16 a it can be seen that the pneumatic piston 26 has at its front end a piston head 30 with seals that pushes the compressed air into the compressed air channel when the rifle is fired. Connected to the piston head 30 is the front end of a rod 31, the rear end as seen in Figure 16 b, engages in a compressed air cylinder 32 and is guided in this displaceable. When clamping the air rifle over the buckling of the air piston 25 is taken from the rear lever 24 b and pushed in the air cylinder 26 to the rear, which in turn the Rod 31 is pushed into the compressed air cartridge 32 and the compressed air volume stored therein is compressed. In its rear end position, when the rifle is tensioned ge, the pneumatic piston 25, which has a recess 33 in its rear region, locked to the nose 34 of a pivoting lever. This pivoting lever is part of a trigger mechanism with trigger lever 35 and sear 36 so that at Be actuation of the trigger 35 of the lever with the nose 34 pivots about its axis 37 and the compressed air piston 25 thereby releases that the nose 34 out of engagement with the savings from 33 of the pneumatic piston 25 passes.

Trigger mechanisms of the aforementioned type are known per se from weapons technology. The peculiarity of the air rifle according to the invention, however, is that the entire cylinder assembly with the compressed air cylinder 26 and the compressed air piston 25 can be replaced with another cylinder assembly, for example, egg nen longer or shorter stroke of the pneumatic piston and / or another compressed air cartridge and / or or a longer compressed air cylinder, so that different Geschos can be generated senergies, but the assembly with the front piece 13 for these different variants can always remain the same. This allows you to keep in modu larer design, the front piece and replace only the cylinder assembly.

The connection between compressed air cylinder 26 and front piece 13 is better seen in Figure 17 as in the sectional view of Figures 16 a and 16 b. FIG. 17 shows a view of a fully assembled rifle with the rifle stock 14. It can be seen there that the cylinder assembly with the pneumatic cylinder 26 does not terminate behind the front piece, but at its front end has a kind of fork 38 so that it laterally surrounds the rear portion of the front piece 13 on both sides. In this way, it is possible, for example, by a screw 39 (in Figure 17 only to be recognized) in the transverse direction the air cylinder 26 via the fork 38 with the front piece 13 releasably connect, so that the cylinder assembly is interchangeable with another and re.

Reference will now be made to FIGS. 18 to 23, and with reference to which an exemplary alternative embodiment of an air rifle according to the present invention will be explained. In this variant, some details are different, which simplify the installation of the air rifle. The overall view of this slightly modified air rifle is shown in Figure 18, which is a longitudinal sectional view. The features to be described here emerge from the respective enlarged detail views, wherein reference is first made below to the enlarged sectional view B according to FIG. 19 in the lower region of the front piece.

19 shows a section through a lower portion of the front piece 13. In the assembly of kinked rifles, it is very important that the longitudinal axis of the barrel is aligned with the longitudinal axis of the system. In the conventional type of mounting that is achieved, for example, via the change of seals whose

Production is very expensive. In contrast, in the solution according to the invention shown in Figure 19, a locking wedge 47 is used, which cooperates with an edge 49 at the rear lower end of the front piece 13 and a recorded in a longitudinal bore of the front piece locking slide 48. This Verrie gelungsschieber 48 is acted upon in the longitudinal bore of the front piece 13 from its inner end side by a compression spring 43. The relative height position of Verrie gelungskeils 47 and its contact surfaces with respect to the locking slide 48 according to the invention via one or more intermediate plates 46, which may have different Materi alstärke determined. Instead of the intermediate plates 46 can also be used under differently thick locking wedges 47. Subsequently, the Ver locking wedge 47 and optionally used intermediate plates 46 fe, for example via a countersunk screw 52 with the other components of the rear portion of Waf fe, ie the pressure cylinder, etc. connected. Through these measures, the coaxiality of the barrel and the system providing the launch energy (compressed air cylinders, etc.) can be set to be repeatable and permanently fixed.

A further detail of this Ausfüh tion variant of the air rifle will be described with reference to Figure 20. FIG. 20 shows in longitudinal section the upper area C of the front piece 13 of the weapon shown in FIG. 18 enlarged. Accordingly, here is an elongated lower-side cutout 44 vorgese hen in the rear region of the barrel 10, which serves to ensure that the barrel 10 during assembly and when tightening the Laufbe fastening nut 12 can not rotate. When mounting the barrel 10 is first pushed into the front piece 13, while aligned with a utility not shown convincing here, which is inserted through a transverse bore of the front piece 13, and then retracted and fixed with the barrel mounting nut 12. When mounting the front piece 13 with the barrel 10 in the overall system a hinge screw 45 is then used instead of the above-mentioned auxiliary tool, which engages through the Querboh tion of the front piece 13 and engages in the elongated cutout 44. Reference is now made to FIG. 21, which shows an enlarged detail of the barrel 10 in longitudinal section at the level of the grain base 15 placed on the barrel (see also FIG. 15). Here, in the front end region of the barrel 10 also a solution 50 is attached to the bottom of the barrel. This cutout 50 serves to accommodate a nose 51 mounted in the inside diameter of the grain base 15. In this way, the grain base 15 can be easily and safely positioned when pushed onto the barrel 10. In Figure 23, this cutout 50 is recognizable at the bottom in vorde ren area of the barrel 10. The above-described elongated cutout 44 on the underside of the barrel in its rear region can also be seen in FIG.
