Definitions

• the invention relates to a self-loading pistol, comprising: a grip, a barrel that is firmly supported on this barrel, an at least partially arranged behind the barrel, in the longitudinal direction of which a movable closure in the longitudinal direction between a front closed position and a rear open position, and a multi-turn, helical closing spring, which Presses the closure into the closed position and is compressed in its open position so that it sits on top of each other with all gears (preamble of claim 1).
• the invention relates to a conversion kit for converting a locked self-loading pistol, which is designed for firing strong pistol cartridges and has: a handle, a movable barrel which can be brought into fixed connection with the bolt, and a closing spring (preamble of claim 4).
• Such a pistol is known for example from German Patent DE 41 09 777 C (HECKLER & KOCH) and is manufactured by the applicant.
• the invention also relates to a weapon system from an optionally locked or unlocked self-loading pistol of the type specified in claim 10.
• Stronger pistol cartridges such as the 9 mm Parabellum cartridge, are usually fired from locked self-loading pistols.
• a locking device usually connects the barrel and the breech so tightly that both, driven by recoil from a shot cartridge, initially cover a common return path. Only then does the closure separate from the barrel and continue its further return path on its own. In the meantime, the empty cartridge case is ejected, an ignition device is cocked and the next cartridge is updated.
• Such cartridges often have particularly weak laborations, which are used, for example, in target shooting. This allows you to optimize the result of the hit, reduce noise pollution, protect the bullet trap or simply protect the cartridge cases when reloading, reduce powder consumption and thus reduce the costs of shooting.
• Such ammunition can also be fired in locked self-loading pistols, the locking devices of which are matched to standard commercial ammunition. However, their recoil is not sufficient to reliably load these weapons. Usually the guns just stay closed and have to be loaded by hand after each shot. Even the above-described pistol with a mass lock cannot load through automatically with such ammunition; if only because its closure is too heavy. Exercises that require the rapid firing of multiple shots cannot be performed with such weapons and such weak ammunition.
• Cartridges of the type mentioned above e.g. 9 mm parabellum
• Cartridges of the type mentioned above are also available in a shot version. Here they are only weakly charged for satisfactory cohesion
• Hikers, lumberjacks, etc. are often used to ward off snakes in snake-prone areas.
• Such a cartridge is usually loaded into the cartridge chamber of a self-loading pistol, while the magazine is loaded with conventional (heavily loaded)
• the shotgun cartridge is then ready. If you encounter larger predators or predators, such as an overgrown dog, you have to load it by hand after you have fired the shotgun cartridge. Then you can use the self-loading pistol in the usual way.
• the invention would like to provide a self-loading pistol that is weak for firing the aforementioned
• Ammunition is set up; also a conversion kit, by means of which a conventional locked Self-loading pistol, which is set up for firing conventional ammunition, can also be converted for firing said weak ammunition; finally a weapon system with a self-loading pistol, which can be set up to fire normal or weakly loaded ammunition.
• the closing spring is closely enclosed from the outside by a sleeve made of elastomer material, the length of which corresponds approximately to the length of the compressed closing spring at the end of the closure return.
• Breech weight and force of the closing spring are designed so that the function of the weapon with the mentioned weakly charged cartridges is trouble-free.
• the buffer arrangement formed from the elastomer sleeve and the compressed closing spring is no longer required for this.
• the breech not only hits the turns of the closing spring that are seated one on top of the other, but also on the elastomer sleeve.
• the elastomer sleeve creates a first buffer effect.
• the length of the elastomer sleeve determines when its damping effect begins.
• the elastomer sleeve can be longer than the fully compressed closing spring. Your optimal length is determined when optimizing the weapon.
• the optimal hardness and hysteresis effect of the elastomer sleeve are determined by the choice of material.
• a shot boar for example, as with a revolver, he only needs to fire the two shot cartridges and can then use the remaining normal cartridges to hit the boar Weir.
• a shotgun cartridge can be loaded as the first cartridge for a targeted warning shot, which may cause minor injuries.
• cartridges of the type mentioned can be loaded in any order regardless of their type and fired without interference.
• the self-loading pistol according to the invention has the advantage over a revolver with its usually only six shots available that it has a much larger magazine filling of e.g. fifteen shots.
• another magazine can be reloaded as often as required in just a few simple steps.
• magazines with special cartridges can be kept ready if necessary.
• the closing spring can be wound from a wire with a round cross section to form a helical compression spring with a round outer circumference.
• the closing spring is preferably formed from a spring steel band (claim 2), so that the individual turns sit flat on one another when the spring is compressed. The risk of lateral deflection of the individual turns when the closing spring is fully compressed is thereby reduced, but not eliminated.
• the elastomer sleeve can then also be loaded transversely to its axis when the closing spring is fully compressed.
• such a spring has proven to be particularly advantageous since it can be subjected to high overloading without being damaged.
• a plate spring assembly can also be regarded as a helical compression spring in the sense of the invention.
• the elastomer sleeve sits when compressed
• Closing spring in a bore of the handle (claim 3), which supports the elastomer sleeve from the outside and influences its deformation properties.
• This bore need not have an inner wall extending over the entire circumference, but can e.g. be open or slotted towards the barrel. This even advantageously prevents the inclusion of an uncontrolled air cushion, which could influence the effect of the elastomer sleeve in an unpredictable manner.
• the invention relates not only to an unlocked self-loading pistol, as described above, but also to a kit for converting a locked self-loading pistol, which can fire normal cartridges and strong cartridges, but not weak cartridges.
• the locked self-loading pistol can be converted into an unlocked self-loading pistol, which can fire cartridges of the same size but of considerably less strength. If necessary, the weak cartridges can be mixed with normal cartridges.
• the conversion kit is set up according to claim 4 for a locked self-loading pistol, which comprises: a handle, a movable barrel which is bingable in fixed connection with the breech, and a helical closing spring.
• this pistol is characterized by an interchangeable barrel that can be attached in the grip, without engaging in the breech, and by a sleeve made of elastomer material that closely encloses the closing spring from the outside, the length of which is approximately that of the length of the compressed spring corresponds.
• the locking spring of the locked self-loading pistol can also be replaced by a replacement locking spring with a different characteristic.
• the closure is usually kept. However, it is also possible to provide an exchange closure, the mass of which differs from that of the original closure (claim 6).
• “Run” is understood here to mean the "run group” which, in addition to the actual run, also includes elements of the locking device belonging to it. Where the actual run can be separated from the elements mentioned, it is even possible to maintain the actual run. Furthermore, the elastomer sleeve requires a space around the closing spring to accommodate this elastomer sleeve. A handle that, due to its construction, does not offer any space for it can also not be converted. As far as the handle can be structurally changed so that this recording space is created if necessary, it is a weapon system discussed below, which consists of a self-loading pistol and a conversion kit.
• a locked self-loading pistol which is particularly suitable for retrofitting is disclosed in the applicant's German patent DE 41 09 777 C.
• a guide is formed at the rear barrel end, which engages in counter-elements on the grip piece when the barrel is moved backwards so that the rear barrel end is moved downward as the barrel continues to move backwards.
• the closure is finally released from the attachment and can move further back alone.
• this attachment is missing, so that the breech can never engage in locked engagement with the barrel.
• the guide is designed to be held firmly in the handle, so that the barrel is not loosely movable in the handle (claim 7).
• a link is attached to the barrel as a guide, which is penetrated by a cross bolt. This is to be replaced by a rigid link.
• the guide is formed by a guide surface that slides along a cross bolt.
• This guide surface is to be replaced by an abutment that finds a firm hold in the cross bolt.
• This lock is similar to the pistol of the above. Patentes DE 41 09 777 C.
• the guide surface slides along a counter-formation of a movable buffer rod, which in turn serves as a guide rod for the closing spring and also has an additional buffer spring.
• this buffer rod is replaced by an exchange buffer rod, which in turn can be fixed immovably in the handle, in which the guide surface is fixed immovably. Since this replacement buffer rod does not perform a buffer movement, it does not have any Buffer spring on. Rather, the replacement closing spring extends over the entire length of the buffer rod and carries the elastomer sleeve on its outside.
• the original known buffer rod has an elongated recess, which can slide over a stationary cross pin in the grip piece, which can be removed for disassembling the weapon, and abuts against it with its limitations.
• the replacement buffer rod has a recess which is not elongated, but is complementary to the cross pin and can thus be held stationary by the latter.
• the barrel is more or less visible from the outside. This applies at least to the surface area of the barrel, which is visible through the ejection opening in the slide when the slide is closed.
• the barrel is usually burnished, but sometimes also bare, nickel-plated, bonded or gold-plated.
• the color of the visible running surface if it is not bare, usually corresponds to the color of the slide surface. In addition, this visible running surface is usually smooth.
• the interchangeable barrel of the conversion kit according to the invention has a different surface design from the original barrel and contrasts as much as possible with the surface of the slide, for example knurled, blued, galvanized with non-ferrous metal or painted.
• the purpose of this embodiment is to give the shooter a constantly visible and sometimes tangible indication that the weapon has just been converted to weak cartridges and is unlocked.
• the invention also comprises a weapon system which consists of a conversion kit of the type described above in connection with claims 4 to 10 and the associated locked self-loading pistol, which can optionally be modified to match the conversion kit.

• the carriage 5 is supported from the front on a closing spring 19 which is guided around a buffer rod 11.
• the rear end of the buffer rod 11 sits under the guide 9, is designed as a counter-guide 13 and accordingly has inclined surfaces complementary to the guide 9.
• the counter-guide 13 On the underside, the counter-guide 13 has an elongated recess 15 into which a cross pin 17 engages with play.

• the barrel 3 and the buffer rod 11 are shown enlarged in FIG. 2; the closing spring 19 and the buffer spring are omitted.
• FIG. 3 shows a conversion kit according to the invention for the pistol of FIG. 1, to be precise on the same scale as in FIG. 2.
• This conversion kit consists of an exchangeable barrel 3 ', an exchange buffer rod 11', an exchange closing spring 19 'and an elastomeric sleeve 24.
• the engagement training 9 'and the counter training 13' are designed and sit in one another so that a mutual relative movement is no longer possible.
• the recess 15 ' is adapted to the contour of the transverse pin 17 (FIG. 1) and forms a pin receptacle, so that the buffer rod 11' cannot move in the longitudinal direction.
• the elastomer sleeve 24 tightly encloses the exchange closing spring 19 'from the outside and is initially located at any point within its length. It is formed from steel strip so that its individual turns rest flat on one another when the exchange closing spring 19 'is fully compressed.
• the elastomeric sleeve 24 is thereby raised and comes into frictional engagement both with the inner wall of the bore mentioned and with the outer surface of the compressed exchange closing spring 19 '.
• the elastomeric sleeve 24 introduces all of the forces introduced from the slide 5 over a large area over the inner wall of the bore and said paragraph 21 into the handle 1. At the same time, a proportion of these forces is introduced via the compressed closing spring 19 'and the buffer rod 11' into the cross pin 17 and via this into the handle 1.
• the unlocked modification of the self-loading pistol according to the invention is obtained by assembling the parts shown in FIG. 3 with the other parts, in particular the handle according to FIG. 1. If an extremely powerful cartridge is accidentally fired with this recoil-free pistol, the carriage 5 is opened very quickly and may rebound very quickly. In no case will the slide 5 and especially the handle 1 be damaged. The recoil energy is introduced over a large area and damped into the handle 1, which in turn, because it is made of plastic, returns the impact "softer" than a handle made of hardened steel.
