Description

The invention relates to a closure for a pistol with a rigid barrel, in particular for small-caliber pistols, training weapons or sporting weapons, according to the preamble of claim 1, which is discussed further below US 8,528,243 B1 and the EP 0 174 901 A2 .

The last-mentioned publication concerns the conversion of an automatic pistol into a single-shot weapon, in particular because it allows aiming and shooting more precisely. One focus is on creating an improved security mechanism. When ready to fire, the cartridge rests on a base formed on a bolt, which in turn is movably mounted in a projection of the slide, a construction that is not mechanically satisfactory.

In a pistol in the prior art, the breech refers to the sum of the components that are intended for feeding and positioning a cartridge and extracting a case.

Practice pistols or training pistols are usually pistols whose external dimensions and/or handling are as similar as possible to a "real" pistol. However, these weapons often have a different caliber, which is often weaker and/or smaller than the actual pistol. Rubber bullets, blank cartridges or colored ammunition are also often used, which require a smaller load. Such pistols represent a preferred area of application for the present invention, as does the use for sporting weapons.

Concepts for training pistols are known from the past, which, analogous to the "real" pistol, have a break-barrel (also known as the "browning system") and a ground lock. These include, among other things, pistols that can be used for color cartridges, for example. However, the relatively heavy slide of a "normal, real weapon" may not be able to be moved backwards enough to automatically complete the loading process with the comparatively weakly loaded cartridges of color ammunition. To solve this problem, the US 8,528,243 B1 a polymer-metal composite slide is proposed, which, among other things, has a bridge to stabilize the composite slide.

The use of polymers in the area of the breech of a pistol, in particular for the production of the slide or at least parts of it, is also used, among other things, in the DE 10 2006 031 657 A1 suggested.

For sport shooters or authorities, training with a break-barreled weapon with a "larger caliber", e.g. 9mm Luger and above, is often too expensive, which is why people often try to use cheaper alternative ammunition during training, such as .22 l.r. to avoid. Even for sport shooters who do not use "larger caliber" pistols, small caliber pistols represent a cost-effective training weapon and/or competition weapon. In these cases too, the requirement for a light slide or breech is given by the smaller load of small caliber pistols, which is why they are often used in the design A tilting barrel system with a ground lock is dispensed with and instead a rigid barrel with a ground lock and a lighter slide is used.

However, the shooter does not want to miss out on the necessary precision even with small-caliber weapons. In the context of this application, tilting barrels are understood to mean those barrels which are arranged to be movable within limits with respect to the frame of the weapon, for example by means of a barrel hook on the breech block, and can tilt downwards during the loading process. In contrast, in the context of this application, a rigid barrel is understood to mean that the barrel of the pistol is not moved relative to the breech block during the loading process. Here the loading process essentially takes place through a straight-line movement of the carriage along the barrel axis. The "rigid" barrel can rest on one or more designated support points on the frame, or on a locking block provided for this purpose, and is therefore not firmly connected to the frame - i.e. by means of screws, for example.

This type of storage of rigid barrels is therefore a challenge because, on the one hand, it should be easy to disassemble and, despite a comparatively small load, high forces still act on the barrel and thus its storage. On the other hand, when installed, the barrel should remain as rigid as possible relative to the frame, for example in order to prevent poor alignment in the horizontal and/or vertical position and still be able to "swing freely" with its muzzle in order to prevent distortion of the barrel in the event of any thermal expansion.

An additional requirement, especially for authorities, is the requirement that a training weapon with a smaller caliber be as similar to a service weapon with a larger caliber as possible in terms of handling.

Since training weapons can also have a high firing load, it is desirable if the weapon is easy to disassemble and made to be as durable as possible.

The invention is a pistol according to claim 1.

The present invention is based on the object of providing a closure for a pistol, in particular small-caliber and/or training pistols, which has a high level of precision. In addition, it is a further task to transfer the handling of a "real" pistol with a break-barrel system to the handling of a small-caliber and/or training pistol with a rigid barrel as analogously as possible. Furthermore, the invention is based on the object of creating, in one embodiment, a locking system for pistols with a rigid barrel that is as easy to disassemble and as robust as possible.

These tasks are achieved according to the invention by means of a closure which has the features specified in claim 1. In other words, it has at least one barrel with a barrel block and a slide with a breech guide, the breech guide being designed to cooperate with a rail guide formed on the frame of the pistol. The barrel is a rigid barrel that experiences no movement relative to the frame during loading. The slide guide has a base with a shock bottom and serves as a sliding or guiding element of the slide in the longitudinal direction of the pistol during the slide movement. In one embodiment, centering rails are formed on the inside of the locking guide in front of the base in the firing direction, which interact in a centering manner with recesses provided on the side of the barrel block during the closing movement in the horizontal and/or vertical direction, relative to the barrel core axis.

The centering rails are designed on the inside of the locking guide to complement the recesses in the barrel block in terms of shape and function. Through the lateral and/or vertical storage of the barrel with the recesses on the Centering rails form a first support or contact pairing, which promotes the repeatable alignment of the barrel.

Despite the use of small-caliber ammunition, mostly with rimfire, and the rigid barrel, the handling of the pistol is almost identical to the handling of pistols that use centerfire cartridges and have a tilting barrel. As a result, the complementary centering rails and recesses can relieve the load on the guide grooves and the rail guide, which increases the durability of the components.

According to the invention, the introduction of force when firing and during the closing process can take place in a relatively straight line along the centering elements mentioned, which promotes a reduction in a tilting moment around the cartridge chamber.

In addition, some preferred embodiments are described below, which describe additional second and/or third system pairings and can solve the aforementioned task in a supplementary manner and can be used together or individually.

In the context of this application, small-caliber pistols are referred to when the caliber is .380 Auto and lower, in particular .22 caliber. The .22 l.r. caliber, which is often used for sports and training purposes, is also included.

Small caliber cartridges are often designed as rimfire cartridges, which require an appropriately designed cartridge chamber and a cartridge extractor that corresponds to the cartridge rim. It should be noted that the embodiments according to the invention can also be adapted relatively easily by a person skilled in the art with knowledge of the invention for use on other calibers and/or centerfire cartridges.

Further components of a pistol, such as the trigger mechanism, are not explained in more detail within the scope of this invention, since the person skilled in the art will depend on the Cartridge type can also make modifications relatively easily based on his specialist knowledge.

In the following, the terms left, right, top, bottom, front and back always refer to the shooting direction of the firearm from the shooter's perspective when it is held ready to fire. The weapon has a central weapon plane running through the barrel axis and oriented vertically, which forms a plane of symmetry, cum grana salis.

The Fig. 1 shows the main assemblies of a pistol comprising barrel 1 with barrel core axis 18, slide 2, frame 3, trigger 34, magazine 35 and handle 36. The barrel 1 has a barrel block 11 on which a cartridge feed ramp 14, as well as a barrel hook 12 on the underside and contact webs on the back 16 are trained.

On the two block side surfaces 111 of the barrel block 11 on the left and right in the firing direction, at least one elongated recess 15 is formed, which is parallel to the barrel core axis 18 and extends from the rear end of the barrel block 11 in the firing direction, thus to the front. The barrel 1 is, as shown, preferably in one piece with the barrel block 11, the barrel hook 12 and a cartridge chamber 13 ( Fig. 4 , Fig. 7 ), but can also be made in several parts.

According to the invention, to save weight, the carriage 2 comprises a locking guide 21 and at least the carriage housing 22. Further components not explained in more detail here, such as a firing pin unit or a closing spring unit, can be arranged on or within the carriage 2, as is known to those skilled in the art. An ejection window 24 and the closure guide 21 with the guide grooves 211 arranged on both sides are, for example Fig.1 and particularly good when viewed together Figs. 3 and 8th visible. The closure guide 21 can be integrated in the slide 2, i.e. made in one piece, or can be connected to the slide 2 in a fixed or dismantled manner as a multi-part design. The slide housing 22 is preferably made of plastic and can also be molded onto the closure guide 21, for example. The carriage housing 22 is preferably by means of the in Figs. 3 , 4 and 8th visible mounting strips 27 connected to the closure guide 21. These mounting strips 27 are formed on the top of the closure guide 21 at least over part of the length and particularly preferably have a substantially L-shaped profile. As a result, the closure guide 21 can also be connected to the slide housing 22, for example by telescoping.

How out Fig. 1 Also visible, the frame 3 with trigger 34, handle 36 and magazine 35 has at least one guide surface 31 on both sides in the upper area, which is complementary in form and function to guide grooves 211 ( Fig. 4 ) of the closure guide 21 are formed. The guide surfaces 31, in cooperation with the guide grooves 211, serve to guide the forward and backward movement of the slide 2 or the closure guide 21 and are known to those skilled in the art.

In Figs. 2a -c normal projections of a pistol according to the invention are shown in the assembled state. The line VI-VI defines the section plane for the views of the Figs. 6a-c ; the line VII-VII is the section plane for the views of the Figs. 7a-c ; the line VIII-VIII is the section plane and viewing direction of the view Fig. 8 .

Like from the Figs. 2a-c As can be seen, the small caliber pistol corresponds externally to a larger caliber pistol, such as the well-known GLOCK 17, and is very similar in appearance. This also has the one shown according to the invention The pistol has a bolt catch lever 33 that protrudes laterally on both sides of the frame 3; likewise a disassembly lever 32 which can be operated on both sides and which, when actuated during the disassembly process, releases the slide 2, in this case with the locking guide 21 attached to it, in the firing direction. The mode of operation of these two levers (disassembly lever 32, bolt catch lever 33) is known to those skilled in the art and should only be mentioned in order to explain the analogous mode of operation with a completely different bolt structure using a rigid barrel.

The Fig. 3 represents the breech guide 21 according to the invention and the barrel 1 in an oblique view from the front and Fig. 4 from diagonally behind. The carriage 2 is not shown for better clarity. At the in Fig. 3 Visible, left side surface 111 of the barrel block 11 in the firing direction is an elongated recess 15 running parallel to the barrel core axis 18. On the right side surface 111, which is remote from the field of view and is not visible, there is also a recess 15 running parallel to the barrel axis 18. This is symmetrically opposite the left recess with respect to the weapon center plane.

At the rear end of the barrel block 11 there is the feed ramp 14, over which a cartridge can slide when taken out of the magazine 35 into the cartridge chamber 13, which is slightly above it in the running direction. In the area of the cartridge chamber 13, i.e. to the side of and/or above, contact webs 16 are formed, which in the exemplary embodiment shown are interrupted by an indicator recess 17. The contact webs 16 formed laterally from and/or above in the direction of the impact base 231 are in the Figs. 4-6 clearly visible. They have outer surfaces 161 in the transverse direction, which run parallel to the central plane of the weapon. The contact webs 16 serve to support the running block 11 at the rear when the shutter is closed, i.e. when the carriage 2 is in the front position, relative to the impact base 231, as is also the case in a synopsis of Figs.6a-c becomes clear.

In Fig. 3 and especially in Fig. 7c the indicator recess 17 can be seen, which forms a kind of recess of the two contact webs 16 in the running direction and preferably runs as an inclined surface, normal to the weapon center plane and from top/front to bottom/back. This creates a kind of when the shutter is closed "Viewing window" is formed from above in the direction of the cartridge chamber 13 or feed ramp 14, which can take on the function of a charge level indicator, since the edge of the cartridge can be seen from the outside. When the shutter is closed, the shooter can therefore see whether there is a cartridge in the cartridge chamber 13 or not.

In Figs. 3 and 4 It can also be clearly seen that the guide grooves 211 are located on the closure guide 21 in the lower area on both long sides. These essentially run from the front to the rear end of the closure guide 21. The guide grooves 211 are designed to complement the rail guides 31 of the frame 3 in terms of form and function. When assembled, the rail guides 31 engage in the guide grooves 211 and enable the slide guide 21 with slide 2 to move back and forth relative to the frame 3. A slide catch catch 28 interrupts the guide groove 211 and allows the slide 2 to engage on the slide catch lever when the slide is open 33 in the rear position, as can be done automatically by the feeder of the empty magazine 35 or manually in a manner known per se. This is also evident from a synopsis with Fig. 5 especially clear.

Like this in particular Fig. 3 shows, the closure guide 21 has an integrally formed base 23. The one-piece design allows high strength and low-torsion movement of the shutter guide 21 relative to the frame 3 as soon as the cartridge is supported on the shock base 231 after the shot has been fired. The shock base 231, which is designed normal to the barrel core axis 18, has a passage opening for the firing pin, as in Fig. 5 visible. Furthermore, one or more base extensions 233 are formed on the base 23 to the side of the butt plate 231, which protrude above the plane of the butt plate in the firing direction.

The extension 233, which is on the side of the weapon that has an ejection window 24 for the sleeve, has, as shown and preferred, a vertical surface, but inclined to the barrel axis 18, which facilitates the ejection of the sleeve.

According to the invention, viewed in the firing direction, at least one elongated, inwardly projecting centering rail 25, oriented parallel to the barrel axis 18, is formed symmetrically to the weapon center plane on the two long sides of the breech guide 21. The centering rails 25 are designed to be complementary in shape to the respective centering recesses 15 of the running block 11. In this way, during the locking process, the barrel 1 is supported horizontally and/or vertically via the barrel block 11 on the locking guide 21. The centering rails 25 can thus take over the storage of the barrel block 11 alone or in addition to the support on the locking block 37. The barrel 1 is thus aligned with repeat accuracy relative to the frame 3 thanks to this measure and can swing freely since contact with the barrel bearing 26 is no longer required.

The design according to the invention and the interaction of centering rails 25 and centering recesses 15 can thus solve the central task mentioned at the beginning and contribute to high precision and repeatability when firing shots. In addition, despite using small-caliber ammunition and a rigid barrel, the pistol can be handled almost identically to the usual use of centerfire cartridges and a break-barreled barrel. As a further consequence, the shape-complementary centering rails 25 and recesses 15 relieve the load on the guide grooves 211 and the rail guide 31, since the introduction of force during the firing of the shot and during the closing process takes place in a relatively straight line along the centering elements mentioned. This improves the service life of the components.

According to the present explanation, it is easily understandable for the person skilled in the art that more than one recess 15 can be formed on each side 111 of the barrel block 11, and similarly the corresponding centering rails 25 on the closure guide 21.

It has proven to be advantageous if the recesses 15 are positioned in a horizontal position symmetrically to the weapon center plane and therefore at the same height.

If only one recess 15 is formed on each side of the running block 11, it is advantageous that the recesses 15 or centering rails 25 are arranged at the level of the running core axis 18. In this way, a reduction in the tilting moment during the closing process can be achieved, since force is introduced almost in a straight line.

The centering rails 25 are preferably designed to run (tapering) towards the end in the weft direction, as can be seen from the top view in FIG Figs. 7 is visible. This course area is referred to in the application and the claims as a (horizontal) centering taper 251, since when the centering rails 25 come into contact with the recesses 15 of the barrel block 11, a horizontal self-centering of the barrel 1 is promoted. In this way, the barrel 1 can be self-centered even when the shot is fired very quickly, which in turn promotes repeatability or precision.

Another preferred embodiment has that in the Figs. 6 shown areas 252 of the centering rails 25 which taper vertically towards the front, at least on one side. The area of the vertical taper of the centering rails 25 can also be referred to as a bevel 252 and is particularly preferably formed on both sides in the vertical direction in the weft direction, i.e. at the top and bottom. This measure also promotes repeatable insertion of the centering rails 25, even with rapid firing succession, and prevents jamming.

When the gun is closed, as in Fig. 6c shown schematically, the barrel 1 is thus supported horizontally and/or vertically on the breech guide 21, whereby a muzzle-side support in the barrel bearing opening 26 is not absolutely necessary. Furthermore, support or contact of the base extension 233 on the running block 11 can be seen.

The butt base 231 also lies against the contact webs 16, whereby a further support and contact surface is formed between the running block 11 and the base 23.

As in Fig. 7 a) to c) As can be seen, the base extensions 233 can limit the impact base 231 in the outward direction, forming impact base side surfaces 232 and interact with the outer surfaces of the contact webs 161 in the closed state. During the closing process, the centering rails 25 are inserted into the recesses 15 and in the example shown, the abutment side surfaces 232 are also used to support and laterally guide the running block 11. In Fig. 7c ) the situation is shown shortly before the closing process is completed, in which it is easy to see for the person skilled in the art that the alignment of the barrel 1 is carried out to a large extent via the interaction of the centering rails 25 according to the invention with the recesses 15 according to the invention to form a contact and support pairing. The base extensions 233 with the surfaces adjoining the contact webs 16 on the outside form a further, second, contact pairing. A third contact pairing can preferably be formed, as shown, between the contact webs 16 and the abutment base 231. Furthermore, with a suitable choice of the gap dimensions in the locked state, a fourth support or contact of the base extension 233 on the running block 11 in the running direction, ( Fig. 6c ) are formed.

The geometries can therefore be easily adjusted by a person skilled in the art in order to optimize the precision and durability of the gun through the shape and position of the recesses 15 relative to the centering rails 25. In addition, the second and/or third and/or fourth contact pairs can be adjusted to one another in the vertical and/or horizontal direction as described in order to prevent horizontal and/or vertical tilting of the barrel 1 by means of the rear and/or side support relative to the base 23 avoid.

The Fig. 8 shows a section through the Fig. 2c ) along line VIII-VIII, with the frame 3 with closing spring and the like not being shown for the sake of simplicity. This cross section is intended to illustrate a possible shape of the guide grooves 211 and the positive reception and/or connection of the closure guide 21 upwards to the slide housing 22, which is preferably made of plastic, in particular a fiber-reinforced polymer. In comparison with Figs. 3 4 It can be seen that the centering rails 25 can continue to run in the outside area and can be designed as mounting rails 27. The chosen representation therefore falls the mounting rail 27 in the image direction as a lateral, essentially L-shaped extension with the respective centering rail 25 together. This one-piece design allows a very space- and weight-saving design of the locking guide 21, with high functionality and good connection to the slide housing 22.

In a special embodiment, the closure block 37 is designed to accommodate and/or support the barrel hook 12 on its surface in a form that is essentially complementary to the latter. The surface of the locking block 37 is preferably designed in such a way that, when viewed in the transverse direction, a trapezoidal, recessed cross-section is created, which forms a vertical and at the same time horizontal support with the correspondingly designed running hook 12.

The closure according to the invention can be produced, for example, by means of machining processes such as milling, turning or grinding, and the closure guide 21 and/or the barrel block 11 can also be designed according to the invention using shaping processes such as forging or hammering, powder metallurgy or MIM, or else using additive manufacturing processes such as 3D printing or a combination of these processes.

The invention is not limited to the exemplary embodiment shown and described, but can be modified and designed in various ways. In particular, the cross-sectional shapes of the strips, rails, recesses, etc. mentioned can be adapted to the specified basic data, and the lengths and positions with respect to the frame can also be easily adapted for the person skilled in the art given knowledge of the invention.

In the description and claims, as already stated above, the terms "front", "back", "top", "bottom" and so on are used in the common form and with reference to the object in its usual position of use. This means that in a weapon the muzzle of the barrel is "front", that the breech or slide is moved "back" by the explosion gases, etc. Transverse to a direction essentially means a direction rotated by 90° to it.

It should also be pointed out that in the description and the claims, information such as "lower area" of an object means the lower half and in particular the lower quarter of the total height, "lowest area" means the lowest quarter and in particular an even smaller part; while "middle area" means the middle third of the total height. This applies mutatis mutandis to the terms “width” and “length”. All of this information has its common meaning, applied to the intended position of the object under consideration.

In the description and claims, "substantially" means a deviation of up to 10% of the specified value, if physically possible, both downwards and upwards, otherwise only in the sensible direction, for degrees (angle and temperature) This means ± 10°. When terms like "essentially constant" etc. are used, what is meant is the technical and not the mathematical deviation possibility that the expert bases this on. A “substantially L-shaped cross section” comprises two elongated surfaces, each of which merges into the end of the other surface at one end, and whose longitudinal extent is arranged at an angle of 45° to 120° to one another.

All quantities and proportions, in particular those defining the invention, as long as they do not relate to the specific examples, are to be understood with a tolerance of ± 10%, so for example: 11% means: from 9.9% to 12.1%. In terms such as: "a solvent", the word "a" is not to be viewed as a numeral, but rather as an indefinite article or as a pronoun, unless the context indicates otherwise.

The term: "combination" or "combinations" stands, unless otherwise stated, for all types of combinations, starting from two of the components in question up to a large number or all of such components; the term: "containing" also stands for "existing out of".

The features and variants specified in the individual embodiments and examples can be freely combined with those of the other examples and embodiments and in particular to identify the invention in the claims without necessarily including the other details of the respective embodiment or the respective example
