    Conversion kit for a firearm and method for converting a
    firearm
    The invention relates to a Umrüstbausatz for a firearm with a handle and a discharge opening having a locked by a movable barrel closure.
    In addition, the invention relates to a use of such Umrüstbausatzes.
    Furthermore, the invention relates to a method for converting a firearm with a handle and a closure having an ejection opening, locked by a movable barrel.
    Finally, the invention also relates to a method for operating a firearm with a handle and a closure having an ejection opening, locked by a movable barrel, wherein the closure is moved to the rear after a shot firing.
    Firearms, in particular self-loading pistols, usually have a closure which closes a barrel when a shot is fired on the back. After a shot firing usually opens the shutter automatically, whereby a cartridge case can be removed from a chamber. To prevent injury, the shutter opens only when a gas pressure has dropped to a safe level. A correspondingly timely opening of the closure can be achieved on the one hand by an unlocked closure, which has a defined mass, so that due to inertia, a backward movement is introduced slowly enough. On the other hand, locked closure systems have become known, wherein the closure is connected to the barrel during the firing of the shot by means of solid locking elements. As a result, a lower weight of the firearm can be achieved compared to an unlocked closure.
    In a Browning system, which is often used for pistols, the shutter is connected by a locking comb with a movable barrel when firing. After triggering the shot of the lock is complete with the run through the 2/33 2
    Gas pressure moves backwards relative to the pistol grip. In this case, the barrel executes a tilting movement defined by a control cam in the grip piece backwards and downwards, while the closure is moved linearly to the rear. Due to the different movement of the barrel and the shutter, the barrel is separated from the shutter 5 during the movement, whereby the shutter is unlocked. Subsequently, a
    Ejection opening between barrel and lock released. Tilting the barrel back and down also causes a cartridge case in a cartridge chamber of the barrel to be accelerated back and down. As a result, the cartridge shell bounces on a cartridge ejector, which is usually arranged below a running axis or in a rear part of the grip piece and underneath the cartridge chamber. In a subsequent rebound from the cartridge ejector, the cartridge case is thrown out of the firearm through the ejection port.
    After the closure has reached a dead center, this is moved forward again by a closing spring which is tensioned backwards during the movement, whereby a cartridge slipping out of a magazine is introduced through a push bottom of the closure and via a feed ramp into the chamber. It also takes the barrel forward to a starting position so that the gun is locked again and ready to fire. Often, a cartridge extractor 20 is provided in the closure to reliably guide the cartridge case on the shock bottom and take off.
    Such firearms having a Browning system are lightweight and insensitive to dirt, so such guns, such as a so-called Glock pistol, are often used by police units, for example. The disadvantage, however, that these guns have only a low intrinsic precision and short ranges of about 50 m due to the movable or tipping, short barrel. Although a self-precision can be improved when using a longer and / or non-tilting alternating barrel, replacement of the dumping, short barrel with a replacement barrel of this type is not compatible with the Browning system.
    A replacement of the tipping, short barrel by a lock interlocking lock leads in particular to the fact that an opening of the closure is not done in time or is not possible and a cartridge case can not be ejected. At 3/33 3
    Use of a non-locking lock the lock opens too early, which is a high risk of injury.
    This is where the invention starts. The object of the invention is to provide a Umrüstbausatz of the type mentioned, with which a timely opening of the closure is then ensured if a lock not interlocking lock is used to increase the precision of the firearm.
    A second object of the invention is to provide a use of such Umrüstbausatzes.
    Further, it is an object of the invention to provide a method of the type mentioned, with which a firearm is easily convertible, so that a timely opening of the closure is ensured after a shot firing when used to increase the precision of the firearm a lock not interlocking change barrel becomes.
    Moreover, it is an object of the invention to provide a method for operating a firearm of the type mentioned, wherein an improved precision of the firearm is achieved and a timely opening of the closure is ensured.
    The first object is achieved by a Umrüstbausatz of the aforementioned type, which comprises a lock releasably connectable to the closure for using a non-interlocking coat, wherein the jacket has a defined mass for the predetermined movement of the closure after firing a shot.
    By connected to the closure jacket to be accelerated after a shot release mass is increased, whereby the acting as a grounding closure opens in time, even if a non-locking lock is used. A mass of the shell therefore results from a mass of the closure, an inserted ammunition and a desired delay time between a shot triggering and an ejection of the cartridge case. As a result, a firearm with a movable, short barrel and low precision can be easily and reversibly converted into a firearm with high precision or high intrinsic precision.
    Because such a jacket can be easily formed, for example, as a steel part, the Umrüstbausatz is produced at low cost and easy to transport. For a particularly good connection between the jacket and closure, it is advantageous if the jacket is formed enveloping the closure. The jacket preferably encloses the closure in a retrofitted firearm on five sides, wherein the jacket has laterally a discharge opening corresponding to an ejection opening of the closure and at a front side a usually round opening for the barrel. When converting the coat is usually placed over the closure or put on this, so that a simple producible, positive connection is given.
    It is advantageous if a cocking slide is arranged on the jacket in order to be able to easily repeat the closure when the jacket is mounted. The cocking slide can be formed directly, for example, by a bolt which is usually releasably connected to the jacket, or indirectly by a part movably mounted in a housing. In such an indirect embodiment, only a contact surface for the cocking slide is provided in the shell, in order to achieve a simple construction. It is advantageous if the jacket has a recess for a spring guide rod on a front side, so that good movability of the closure together with the jacket relative to the grip piece and the spring guide rod connected to the grip piece is provided.
    It can also be provided that a contact surface for the closing spring is provided directly on a front side of the jacket, in particular if the jacket is designed for a firearm in which a so-called bushing is not absolutely necessary, for example a so-called Colt-M1911 gun. 5/33 5
    In many pistols such as the Glock pistol, it is possible to enable a continuous fire operation by attaching a continuous fire device in the jacket. A lever for switching between a continuous fire mode and a single fire mode may be positioned in the shell or in a housing connected to the gun for ease of construction. It is favorable if a jacket for a pistol with a continuous fire device arranged in the closure, for example a Glock pistol model 18, has a recess through which a switching lever or switching button of the continuous firing device can be operated in order to be able to operate it easily.
    Advantageously, the jacket has a fixing recess for fixing to the closure by a cartridge extractor protruding from the discharge opening. As a result, a very stable, positive connection between shell and closure can be formed. Especially with Glock pistols, the cartridge extractor protrudes from the ejection opening of the shutter when a cartridge is loaded, so that a fixation can be easily ensured by a corresponding corresponding recess in the jacket. In addition, the coat is fixed to the closure by the replacement barrel inserted in the converted firearm, and guided in a movement to the rear of the replacement barrel.
    In order to ensure a function of a slide catch, it is favorable if the jacket has a catch catch which widened a catch catch of the closure, in order to increase a contact surface with the slide catch. As a result, an excessive pressing of a surface serving as a catch on the closure can easily be avoided.
    It is advantageous that the Umrüstbausatz includes a connectable to the firearm reset means by which a force in the closure of a cartridge case in the direction of a arranged in the firearm cartridge ejector is exercisable. With such a restoring device, a movement of the cartridge case to the cartridge ejector is achieved during a movement of the closure together with the cartridge case to the rear after a shot triggering, usually downwards. Characterized a contact of the cartridge case with the cartridge ejector is ensured even when a rigidly connected to the handle barrel 6/33 6 is used and the cartridge ejector is arranged below the barrel axis or below the cartridge chamber, as is common in the Glock pistol , With such a restoring device, a reliable ejection of a cartridge case in such a firearm can thus be achieved even if a rigid alternating barrel is used.
    In firearms, in which the cartridge ejector is not arranged below the barrel axis or below the cartridge chamber, such a return device is not required. Such firearms have, for example, a groove in a shockbore, through which a central cartridge ejector projects, onto which the cartridge shell bounces after a shot being fired and is thus ejected.
    A structurally simple and robust design is achieved when the restoring device is arranged in the jacket, preferably at a position corresponding to the ejection opening.
    Conveniently, the restoring device is designed as a flat spring. This ensures a very cost-effective manufacturability. When the flat spring is positioned in the jacket, a connection of the flat spring with the jacket usually takes place in a form-fitting manner through a shaping groove, for example a dovetail groove. However, the flat spring normally disposed between shell and closure may also be connected to an attachment recess at an additional bend by a connecting means such as a screw or bolt to the shell.
    It is advantageous if the leaf spring is arranged on a corresponding to a groove for a running approach in the closure position in the jacket. As a result, the leaf spring can protrude through this groove in the firearm, whereby a conversion with very little effort is possible.
    When feeding a cartridge from the magazine from below, the flat spring is pushed up, with an approximately vertical force is exerted downward on the cartridge. A lifting of the shell from the closure due to this vertical force is ensured by the barrel, which fixes the coat on the closure, so that a function of the firearm is guaranteed. 7/33 7
    When the cartridge is pulled out by the shutter moving backward upon firing of a shot under the action of gas pressure, the leaf spring continues to push down the cartridge shell so that it is moved down relative to the barrel axis to the cartridge ejector and, as in a tipping barrel operation, to FIG Cartridge ejector bounces. At the cartridge ejector, the cartridge shell bounces off and is ejected through the ejection port.
    Advantageously, a rigidly connectable with the handle changeable barrel is provided, which is preferably inserted from the front into the closure. As a result, the intrinsic precision 10 of the firearm is increased because the barrel does not tip over after the shot has been fired, whereby a position of the barrel to a target device always remains the same. In general, the removable barrel is detachably connectable to the handle so that the firearm can be easily and reversibly converted from a Browning system with tipping barrel to a firearm with a rigid barrel. In order to further increase the precision, in particular the self-precision, of the firearm, it has been proven that the replacement barrel is designed to be longer than the movable or tipping barrel usually located in the firearm. For ease of assembly, the change-over barrel is preferably designed such that it can be introduced from the front through the opening into the closure. Normally, the alternating barrel, which is advantageously substantially rotationally symmetrical, as a rule cylindrical, has different diameters over a run length and shoulders at a transition between the different diameters, so that a defined stop of the change barrel is provided at a mounting position. 25
    The interchangeable barrel can be indirectly rigidly connected directly or via an intermediate piece with the handle, usually by screws and / or clamps. A simple and robust construction results when a releasably connectable to the handle housing is provided through which the removable barrel is indirectly connected to the handle, preferably non-positively. The housing may also be designed for a positive and non-positive connection in order to achieve a high accuracy of fit with the handle. A connection between the housing and the removable barrel can be done, for example, by a threaded part arranged in the housing, to which the alternating barrel can be fixed by means of a union nut or another fixing means 8/33. It can be provided at the interchangeable barrel, in particular on a shoulder of the interchangeable barrel, a groove or flat and on the threaded portion a corresponding elevation in order to achieve a stable, positive and non-positive connection. This also allows easy insertion of different barrels with different run lengths.
    A very stable connection between the housing and the handle results in a structurally simple manner, when two half-shells are provided, which have a negative mold of a part of the handle and on the one hand with the handle and on the other hand connected to the housing. As a result, on the one hand, a large contact surface is achieved with little pressure between the half shells and the grip piece, so that wear is reduced when the half shells are positively connected to the grip piece. On the other hand, a connection to the housing can be made easily and quickly, for example, by a shaft connecting the housing and the half-shells, which is preferably fixed by means of a quick release lever and a Wellenfixiermutter. A power transmission between the housing and the half shells takes place over a large area and with low surface pressure, in particular when a shaft with a large diameter is used. In order to minimize a load on the handle, an insertable support in the housing may be provided on a rear side of the handle, through which a stable connection between the handle and the housing is achieved. For firearms with a stopcock, such as the Colt-M1911 pistol, it is favorable if no corresponding support is provided in order to achieve a good operability of the cock. The housing may be similar to a shaft system available under the trade KPOS system.
    By a shaft mounted in the housing with a semi-circular cross-section, a connection between the half-shells and the housing can be made with a high accuracy of fit. In addition, this achieves a simple and fast fixability. For this purpose, the shaft is inserted through a guide with a cross section corresponding to a narrow side of the semicircular cross section in the half shells and rotated at a Wellenfixierausnehmung with a cross section corresponding to a broad side of the semicircular cross section through 180 °, whereby a positive connection is made. In contrast to the KPOS system, there is a fixing 9/33 9 by pivoting the quick release lever by 180 °, so that the quick release lever can be pivoted after fixing in the recess and a position of the quick release lever, in contrast to the KPOS system is irrelevant. This improves handling. 5
    In addition, a so-called Picatinny rail can be provided on the half shells, so that more accessories can be connected to the handle via the half shells. Usually a Zuführrampe part of the barrel and cohesively connected to a rear end 10 of the barrel with this, are passed over which from the magazine nachrutschende cartridges in the cartridge chamber. In the case of a removable barrel which can be introduced from the front into the closure, this is generally not possible due to a size of the opening in the closure. In order nevertheless to ensure a supply of cartridges, it is advantageous to provide a feed ramp which can be introduced through the ejection opening into the firearm. 15 A connection of this separate feed ramp with the handle is usually form-fitting, preferably on a control cam or a chain link axis, which defines a Abkippbewegung during a tipping run, whereby the feed ramp is fixed in the longitudinal direction. It is advantageous if the feed ramp is finally fixed by introducing the removable barrel, which usually protrudes in the built-up state up to the feed ramp. For example, this can be done by a positive fixation of the feed ramp in the control cam, wherein the feed ramp is fixed between the control cam and removable barrel.
    The precision of the firearm can easily be further improved if an attachable with the firearm stop shaft is provided. As a result, the weapon can be easily taken in a shoulder stop, whereby an improved goals is possible. In general, the stop shaft with the firearm is indirectly connected by the housing. Usually, a hinged connection between the housing and stop shaft is provided so that the housing is stowed on the one hand on a small space and on the other hand, the stop shaft can be quickly folded into a firing position when needed.
    Timely closure of the closure and fast loading of a converted firearm are easily ensured if an exchange closing spring 10/33 10 is provided for resetting the closure after a firing shot having a higher rigidity than a recoil spring inserted in the firearm. Due to the increased rigidity, despite the increased by the shell, to be accelerated in a loading movement masses rapid charging. The 5 replacement closing spring can be used instead of the original closing spring or an additional spring, which is connected in parallel with the original closing spring. For example, an additional closing spring may be connected on the one hand in a rear region of the housing and on the other hand with the jacket, preferably on an upper side, so that an overall spring stiffness is increased even using the original closing spring. A particularly simple retooling is possible if a stiffer closing spring is used instead of an original closing spring, for example, can be used to retrofit a gun Glock 19 a closing spring a gun Glock 17 type. A spring force results depending on the selected length of the replacement barrel and mass of the shell. Thus, even with a lighter coat, a stronger replacement closing spring may be required. However, it can in principle, depending on the vote of run length and mass of the shell, and the original closing spring can be used. It is advantageous if a firearm with a handle, a discharge opening 20 having closure and a cartridge ejector is retrofitted with a Umrüstbausatz invention. This can be improved in a simple manner and at low cost, the precision of the firearm. Because retrofitting with the retrofit kit according to the invention is reversible, the firearm, for example, can be retrofitted easily and quickly into an original state with a tilting barrel and low weight, for example, after long-range use.
    The second object is achieved in that an inventive conversion kit is used to convert a firearm with a movable barrel on a firearm with a rigid barrel. As a result, the intrinsic precision of a firearm is improved in a simple manner.
    The further object is achieved in that in a method of the type mentioned for converting a firearm for use of the lock non-interchangeable alternating barrel, a jacket with the closure releasably connected 11/33 11, wherein the jacket a defined mass to the predetermined Movement of the closure after a shot firing has. Because an additional weight for the closure is formed by the jacket, a timely opening of the closure is thus ensured in a simple manner even when using a rigid, non-locking lock the interchangeable barrel. A connection of the shell with the closure is usually carried out by a form-fitting closure by a coat enveloping the closure.
    In order to ensure ejection of the cartridge case even with firearms with a cartridge ejector positioned below a barrel axis, a restoring device is expediently connected to the firearm, by means of which a force in the direction of a cartridge ejector arranged in the firearm can be exerted on a cartridge case located in the closure. Usually, this is a sheath-mounted flat spring.
    High reach and improved precision can be easily achieved by replacing the barrel with a removable barrel rigidly connected to the handle. For a simple conversion, it is advantageous if the removable barrel is inserted from the front into the closure. Furthermore, it is easily possible to use a change barrel that is longer in relation to an originally inserted barrel.
    Conveniently, the firearm is preferably non-positively connected to a housing, which connects the removable running indirectly with the handle. As stated above, this is normally done via half-shells, which are connected to the handle frictionally and / or positively releasably.
    To ensure a cartridge feed when using a removable barrel, it is advantageous if a feed ramp is inserted through the ejection opening in the firearm and positively connected to the handle.
    The further object is achieved in that in a method of the type mentioned for operating a firearm, the closure is not 12/33 12 interlocking interchangeable barrel is used and the shutter after firing shot due to a releasably connected to the closure shell with a defined mass only opens after a predetermined time. As a result, with a conventional firearm, a high range and simultaneously improved precision can be achieved. In addition, the firearm can easily be converted back to an original state with tipping barrel, since the jacket and the removable barrel are usually reversibly connected to the firearm. The predetermined time, after which the shutter opens, is usually that time within which a gas pressure in the alternating operation has dropped to an uncritical value.
    Preferably, force is applied to a cartridge case in the direction of a cartridge ejector disposed in the firearm by a return means connected to the firearm whereby the cartridge case rebounds toward the cartridge ejector as the closure is moved and ejected through the ejection port. This ensures a cartridge ejection even if a firearm is used with a arranged below the barrel axis cartridge ejector.
    Further features, advantages and effects of the invention will become apparent from the embodiment illustrated below. In the drawings, to which reference is made, show:
    1 and 2 exploded views of a converted firearm;
    Fig. 3 is a plan view of a converted firearm;
    4 to 8 sectional views of a converted with a Umrüstbausatz invention firearm;
    9 to 12 a detail of a converted firearm in different views.
    Fig. 1 and 2 show a converted with a Umrüstbausatz invention firearm 1 in an exploded view. Shown is a retrofitted Glock gun, which typically has a dumping barrel that closes a closure 2 according to a Browning system. 13/33 13
    In order to achieve an increased range and improved precision with the Glock pistol, instead of the original barrel in the retrofitted firearm 1, a replacement barrel 4 is inserted, which is rigidly connected to an original grip 7 of the Glock pistol via a threaded portion 16 and a housing 19 connected is. Since the interchangeable barrel 4 is not tilted or not movable and is designed without a locking comb corresponding to the closure 2, the interchangeable barrel 4 does not close the closure 2 even when a shot is fired.
    A structurally simple construction of Umrüstbausatzes is achieved because in an inventively retrofitted firearm 1 of the original shutter 2 of the Glock pistol is used. In order to ensure a timely opening of this closure 2 despite the use of a non-interlocking lock 4 after a shot triggering, a jacket 3 enveloping the closure 2 is provided, which has an inner contour corresponding to an outer contour of the closure 2. This is connected to increase a mass of the closure 2 releasably connected thereto.
    To produce a connection between the closure 2 and the jacket 3, the jacket 3 is placed on the closure 2. On a front side of the shell 3 is a preferably round, 4 for changing clearance corresponding jacket opening 43 is provided, through which the interchangeable barrel 4 in the closure 2 insertable and with the firearm 1 is connectable. As a result, the jacket 3 is fixed on the closure 2 and a release even with a movement of the closure 2 relative to the handle 7 is simply prevented. With an inserted cartridge 36, the shell 3 is further connected by a laterally pressed out to the outside cartridge extractor 27 with the shutter 2 at a Fixierausnehmung 28.
    The interchangeable barrel 4 is connected to the handle 7 by a housing 19 by means of a threaded portion 16, wherein the threaded portion 16 is fixed in the housing 19 by fixing screws 18. With the threaded portion 16 of the interchangeable barrel 4 is connected by means of a union nut 17, as is common in other weapons, for example, in a so-called Uzi. For a secure, positive connection, a survey 35 is provided on the threaded portion 16, which corresponds to a flat 34 on a shoulder 33 of the interchangeable barrel 4. The union nut 17 is fixed by 14/33 14 a locking pin 31 and a Sicherungsstiftfixierschraube 32 in a closed state on the threaded portion 16.
    A connection of the housing 19 with the handle 7 takes place on the one hand by a form-fitting of the handle 7 corresponding inner contour of the housing 19. On the other hand, a positive and non-positive connection between the housing 19 and handle 7 indirectly by two between the housing 19 and the handle. 7 These have each one to a part of the handle 7 corresponding half shell inner contour 44, which allows a large-area connection with the handle 7, so that a surface pressure and wear are minimized. A connection between the half-shells 11 and the housing 19 is realized by a shaft 12 mounted in bores 13 of the housing 12, which at least partially has a non-circular cross section, preferably a semicircular cross section. Correspondingly, a guide 41 and a Wellenfixierausnehmung 40 are provided in the half-shells 11, wherein the shaft 12 is feasible only with rotated in a certain position cross-section through the guide 41 to the Wellenfixierausnehmung 40. In the illustrated embodiment, a center of gravity of the shaft 12 must be turned down. At the Wellenfixierausnehmung 40, the shaft 12 is rotated by 180 °, so that a stable connection at a contact surface between the shaft 12 and Wellenfixierausnehmung 40 and between the half-shell inner contours 44 and the handle 7 results. In order to fix the shaft 12 in this position, a quick-release lever 10 is provided at one end of the shaft 12 and at a further end of the shaft 12 a Wellenfixiermutter 39, so that the shaft 12 can be fixed non-positively on the housing 19.
    The interchangeable barrel 4 is designed substantially rotationally symmetrical for insertion from the front into the closure 2 and, in contrast to an originally inserted barrel, has no end feed ramp 9 for a cartridge feed, for which reason the conversion kit comprises a separate feed ramp 9 which passes through the ejection opening 26 in FIG the firearm 1 is inserted.
    In a Glock pistol, a cartridge ejector 29 is usually arranged below a running axis 37 or below a cartridge chamber 8. By the original tilting barrel 15/33 15 a cartridge case is accelerated after a shot trigger down in the direction of the cartridge ejector 29 and ejected from this rebounding. In order to achieve a safe ejection of the cartridge case in spite of the used, rigidly connected to the handle 7 change cycle 4, a connected to the shell 3 flat spring 23 is provided which pushes the cartridge case down so that a cartridge case upon a return movement of the closure 2 bounces upon a shot firing on the cartridge ejector 29 and then ejected through the ejection opening 26. The flat spring 23 is bent, attached to the end of the shell 3 in a fastening recess 38 and executed with a corresponding to a groove 24 of the closure 2 dimension. As a result, the flat spring 23 can be inserted through the groove 24 of the closure 2 through the closure 2 into the firearm 1.
    In order to bring the closure 2 and the shell 3 back to a front position or a loading position after a shot release from a rear end position, an exchange closing spring 5 is provided, which is guided by a spring guide rod 6 of the original Glock pistol. Depending on the vote, the exchange closing spring 5 can have a higher rigidity than a closing spring normally used in the firearm 1, in order to initiate a movement forward with corresponding acceleration despite increased masses to be accelerated and to enable rapid loading.
    Further, a catch catch of the closure 2 extending catch catch is provided on the jacket 3, to increase a contact surface and to avoid excessively high pressures on the catch catch of the closure 2.
    In the illustrated embodiment, an original magazine 15 of the Glock pistol is used. Alternatively, a larger or longer magazine 15 can be used to increase a cartridge capacity.
    On an upper side of the housing 19, a Picatinny rail 30 is provided, on which further accessories can be detachably mounted, for example a target device.
    Furthermore, corresponding rails for mounting additional accessories can also be arranged laterally on the housing 19. A corresponding Picatinny rail 30 is 16/33 16
    Advantage also arranged on an underside of the half-shells 11, so that the Umrüstbausatz is expandable in a simple manner.
    The jacket 3 has a cocking slide opening 22, in which a cocking slide 20 5 is detachably fixed, so that the converted firearm 1 can also be easily loaded manually. By a provided in the housing 19, elongated Spannschieberausnehmung 21 of the jacket 3 and the shutter 2 moving clamping slide 20 can be moved relative to the housing 19 even when the housing 19 is mounted. When retooling the cocking slide 20 is inserted through the 10 clamping slide recess 21 of the housing 19 in the cocking slide opening 22 of the shell 3, after the jacket 3 and the housing 19 are mounted.
    Fig. 3 shows a converted with a Umrüstbausatz invention firearm 1 in a plan view. In this case, the housing 19 is connected to the handle 7 through 15 the shaft 12, which is fixed by means of the quick release lever 10 on the one hand and by means of a Wellenfixiermutter 39 on the other hand on the housing 19. Furthermore, the change-over shaft 4 connected to the housing 19 by the union nut 17 and the cocking slide 20 located in a rear end position, by means of which the firearm 1 can be loaded manually, are shown. 20
    Fig. 4 shows a section through a firearm 1 along the line IV-IV in Fig. 3. It can be seen that the closure 2 and the shell 3 are in a rear end position, wherein the exchange closing spring 5 is compressed. Upon a forward movement of the shutter 2, the cartridge 36 is guided by relaxation of the exchange closing spring 5 via 25 the feed ramp 9 in the chamber 8, wherein the forward movement of the shutter 2 is transmitted through a push bottom 45 on the cartridge 36.
    At the same time the cartridge 36 is pressed in the forward movement by the feed ramp 9 upwards, wherein the flat spring 23 is pressed elastically upwards. The feed ramp 9 is arranged as shown on a control cam 42 in the handle 7 and 30 is fixed by the rigidly connected to the handle 7 changeable barrel 4.
    It can also be seen that the housing 19 is connected to the half-shells 11 by the shaft 12, wherein the half-round cross-section of the shaft 12 in the 17/33 17
    Wellenfixierausnehmung 40 is rotated upward to make a positive connection.
    As shown, the barrel is connected to the handle 7 through the union nut 17 and the threaded portion 16, wherein the threaded portion 16 in the housing 19 through
    Fixing screws 18 is attached. A connection between the union nut 17 and the threaded portion 16 is ensured by a locking pin 31 and a Sicherungsstiftfixierschraube 32. FIG. 5 shows a section through a firearm 1 along the line V-V in FIG. 4.
    It can be seen, the fixing of the housing 19 to the half-shells 11 through the shaft 12 by means of the semi-circular cross-section of the shaft 12 in a central region. A resulting from the half-round cross-section, in an axial section approximately rectangular wave recess 14 allows insertion of the shaft 12 in the guide 41 of the 15 half-shells 11 when the shaft 12 is rotated relative to the position shown by 180 °. In the illustrated position, the shaft 12 is fixed by the quick release lever 10 and the shaft fixing nut 39.
    It can also be seen that the housing 19 on an upper side and the half-shells 11 20 on a lower side have a dovetail-like cross-section. With a corresponding profile in each case a Picatinny rail 30 is formed for receiving accessories.
    Fig. 6 shows a section through a firearm 1 along the line VI-VI in Fig. 4. 25 It can be seen that a cartridge 36 is positioned at an upper end of a schematically illustrated magazine 15. Further, a cartridge extractor 27 and the flat spring 23 are shown, which are elastically moved when loading the cartridge 36. In this case, the resiliently executed cartridge extractor 27 is moved to the side, wherein this engages in a fixing recess 28 of the shell 3 and thus this 30 positively fixed to the closure 2. The restoring device, which is in a relaxed position and is designed as a flat spring 23, is pushed up when the cartridge 36 is loaded, with a force being exerted on the cartridge 36 downwards. Further, the cartridge ejector 29 arranged below the barrel axis 37 is shown, which bounces off a cartridge case after a shot firing and is ejected through the ejection opening 26 formed in the cap 2 and in the barrel 3.
    In Fig. 7 is a firearm 1 shown in FIG. 3, wherein closure 2 and 5 jacket 3 are moved from the rear end position back to a front end position and the exchange closing spring 5 is relaxed. In addition, there is a cartridge 36 in the chamber 8, so that the firearm 1 is loaded. The flat spring 23 is elastically deformed by the cartridge 36 and pushed upward, so this exerts a force on the cartridge 36 down. 10
    Fig. 8 shows a section through a firearm 1 along the line VIII-VIII in Fig. 7. As shown, the shell 3 is fixed in the position shown by the outwardly displaced cartridge extractor 27 on the closure 2, since the cartridge extractor 27 in the Fixierausnehmung 28 of the shell 3 engages. As a result, 15 a positive fixation of the shell 3 is ensured on the closure 2.
    9 to 12 show in various views a detail of a converted firearm 1, wherein a shell 3 including closure 2 and flat spring 23 existing assembly is shown. FIG. 12 shows a section through the assembly 20 along the line XII-XII in FIG. 11. It can be seen that the jacket 3 encloses the closure 2, so that a positive connection is provided. It can also be seen that the flat spring 23 fastened in the fastening recess 38 is arranged between the jacket 3 and the closure 2 and projects through the groove 24 into the firearm 1. In addition, the ejection opening 26 and the 25 Fixierausnehmung 28 can be seen, in which the cartridge extractor 27 engages with loaded cartridge 36 to fix the jacket 3 on the closure 2. At a front end of the shell 3, the shell opening 43 is provided through which the removable barrel 4 is inserted into the firearm 1. Further, a recess 25 is provided for the spring guide rod 6 at a front end of the shell 3, to allow a 30 movement of the shell 3 after a shot release to the rear. In a rear area, the jacket 3 has the cocking slide recess 21, in which the cocking slide 20 can be connected to the jacket 3, so that the firearm 1 can be manually loaded even when arranged in a housing 19. 19/33 19
    To convert a firearm 1 such as a Glock pistol, the magazine 15 and the shutter 2 are released from the firearm 1 and removed an original barrel and an original closing spring. Subsequently, the exchange closing spring 5 is fixed in the handle 7 and the shutter 2 is again connected to the handle 7, after which the feed ramp 9 is inserted through the discharge opening 26 in the closure 2 and arranged on the control cam 42. In a next step, the jacket 3 is placed on the closure 2, after which the housing 19 is connected by the shaft 12 with the handle 7. Finally, the cocking slide 20 are fixed by the Spannschieberausnehmung 21 in the cocking slide opening 22 and the interchangeable barrel 4 connected via the firearm 1 housing 19 by the threaded portion 16 and the union nut 17 rigidly connected to the handle 7, whereby the Zuführrampe 9 fixed to the cam 42 is. Through the interchangeable barrel 4 and the shell 3 is fixed to the closure 2. Now the magazine 15 can be used again and the firearm 1 loaded.
    With a conversion kit according to the invention a firearm 1 with low mass and short range such as a Glock pistol can be converted very easily changing a locking system and a run length to a carabiner system, which has an increased range of more than 100 m and improved inherent precision , A conversion can be done quickly and reversibly, so that a change from a state with a tipping barrel to a state with an extended, rigid alternating barrel 4 is easily possible. Because multiple parts of the original firearm 1 as the shutter 2 and the handle 7 can be used and the additional required for the Umrüstbausatz components, for example, by turning or milling, can be produced, a production of a corresponding Umrüstbausatzes with little effort is possible.
    The cost of a Umrüstbausatzes invention are only slightly above the cost of commercially available shaft systems, for example, under the trade KPOS (Fab Defense) or TRIARII (Hera Arms) are known, but can with a Umrüstbausatz invention, in contrast to known shaft systems also a range and an intrinsic precision of a Firearm 1 can be improved. 20/33
