Description

technical field

The invention relates to a closing spring device for a handgun. The invention also relates to a handgun with the closing spring device.

State of the art

A firearm or handgun is a ballistic device in which a projectile is propelled by means of very rapidly expanding hot gases called propellant gases. The firearm typically has a barrel and a receiver, with the receiver being located in whole or in part behind the barrel. At its rear end, the barrel has a cartridge chamber for receiving a cartridge and an exit opening for a projectile of the cartridge arranged in front of the cartridge chamber. The housing typically has a locking device or locking device with a firing pin arranged within it, a recoil spring device, and a trigger device. Furthermore, the housing typically has a magazine for cartridges, with at least one cartridge being able to be moved from the magazine into the cartridge chamber. The locking device closes the barrel, in particular the cartridge chamber, to the rear, together with the cartridge case, prevents the propellant gases from escaping to the rear and serves as a counter bearing for the cartridge. Furthermore, the locking device can take over other functions, such as loading, firing, securing and unloading the firearm. The closing spring device is typically arranged behind the closure device and is at least operatively connected to it.

Different closing spring devices are known. For example from the DE 000001578397A a recoil spring device for an automatic firearm is known. The closing spring device has a closing spring. From the DE19915646C2 a closing spring device is known, which is also referred to as a closing spring assembly. The closing spring device is operatively connected to a breech and a barrel of the handgun.

Presentation of the invention, task, solution, advantages

It is the object of the invention to provide an improved recoil spring device for a handgun. Furthermore, the task is to provide an improved ignition device.

Furthermore, it is the object of the invention to provide an improved handgun.

The object is achieved by a closing spring device having the features of claim 1 and a handgun having the features of claim 27.

Advantageous configurations of the closing spring device and the handgun can be found in the dependent claims.

The object is achieved by a recoil spring device for a handgun, which has a spring guide device and at least one recoil spring. The closing spring device is characterized in that the spring guide device has a first closing spring guide tube and at least one second closing spring guide tube, which has at least one closing spring, a first closing spring and at least one second closing spring and a spacer element is provided, with the spacer element being located axially between the first closing spring and the at least second closing spring is arranged. The spacer element advantageously makes it possible to design the closing spring in at least two parts.

The handgun has a central axis. The spring guide device is preferably arranged on a central axis of the handgun, as a result of which an asymmetrical application of force by the locking device to the closing spring device can be avoided. The weapon barrel, a locking device and the locking spring device are preferably arranged along the central axis. The central axis of the handgun essentially corresponds to a weapon barrel axis of the handgun. The spring guide device can guide the recoil spring, in particular the first and at least the second recoil spring, during a linear movement along the central axis of the handgun and prevent it from buckling. When the handgun is dismantled in the field, for example for cleaning, the weapon housing is generally opened and the locking device removed, with the locking spring device having to remain together as a prestressed unit. In this case, the closing spring device preferably remains together with the first closing spring, the spacer element and the at least second closing spring together with the closing spring guide tubes as a component group. The closing spring device is preferably attached to the closure device.

In particular, the spacer element is linearly movable relative to the first closing spring guide tube, in particular along a central axis of the closing spring device relative to the first and/or second recoil spring guide tube movably arranged. The spacer element is preferably arranged in a linearly displaceable manner in relation to the first closing spring guide tube. Thus, the unit made up of the first closing spring, spacer element and at least second closing spring can be moved linearly and relative to the spring guide device.

The second closing spring is preferably mounted in a floating manner, at least in sections, on the first closing spring guide tube and the second closing spring guide tube. Floating is understood to mean that a relative movement along the central axis is possible. In this case, the spacer element can be displaced in the longitudinal direction of the recoil spring device of the handgun relative to the first recoil spring guide tube. The spacer element preferably retains its radial position relative to the first closing spring guide tube. The spacer element can thus be blocked radially with respect to the first closing spring guide tube. In particular, the spacer element can be supported radially with respect to the first closing spring guide tube during operation. As a result, the spacer element is mounted so that it can move linearly and is supported radially with respect to the first closing spring guide tube. The spacer element is preferably arranged on/or on the first closing spring guide tube. The spacer element is preferably plugged onto the first shooting spring guide tube. It is advantageous here that the spacer element cannot move in an uncontrolled manner during operation.

The spacer element preferably has an inner and/or outer geometry which ensures that the spacer element does not rotate relative to the weapon housing within the weapon, but is supported radially, as specified by the design, and thus only moves longitudinally to the weapon housing can. By dividing the recoil spring, the overall length of the handgun can advantageously be significantly reduced. The first closing spring guide tube and the second closing spring guide tube preferably form a guide for the first and/or the at least second closing spring of the closing spring device. The first closing spring guide tube and the at least second closing spring guide tube are constructed in at least two parts so that they can be telescoped, with the first closing spring guide tube preferably being able to be pushed over the at least second closing spring guide tube and/or pushed away from it again, with pushing over and/or pushing away being referred to as a telescoping movement. The telescoping movement can preferably take place along, preferably on or parallel to the central axis.

The interface between the first closing spring guide tube and the second closing spring guide tube preferably has an undercut. The undercut at the interface between the two telescoping recoil spring guide tubes, the first recoil spring guide tube and the second recoil spring guide tube, ensures that the recoil spring, in particular the second recoil spring, the two telescoping recoil spring guide tubes when the housing of the handgun is open at the rear and/or out of the housing the locking device removed from the handgun with the preferably attached closing spring device cannot be pushed apart and the closing spring, in particular the second closing spring, cannot relax in an uncontrolled manner.

The two telescoping closing spring guide tubes essentially preferably have a cylindrical cross section. However, the telescoping closing spring guide tubes, the first closing spring guide tube and/or the second closing spring guide tube, can also have any other desired cross section, for example a square cross section. The cross section of the first and/or the second closing spring guide tube can deviate from a cylindrical cross section over the entire length or only in sections.

The closing spring device is preferably in operative connection with a locking device of the handgun. The closure device preferably has at least one closure head and one closure carrier. There is preferably no operative connection between the second closing spring and the lock carrier of the locking device. In particular, the second recoil spring is not in operative connection with the bolt carrier when the handgun is in the basic position ready to fire and/or is in firing mode.

During a movement along the central axis of the handgun, the second recoil spring can be supported with a front recoil spring end on the spacer element. The first closing spring and the second closing spring can be spaced apart by the spacer element. The first closing spring and the second closing spring have the task, in particular, of returning the locking device to its initial state during operation of the handgun after a backward movement of the locking device. In this case, the spring force and the effective lengths of the first closing spring and the second closing spring are matched in total in such a way that the locking device of the handgun can initially slide backwards properly and then move forward again into the basic firing position of the weapon.

In particular, the closing spring has at least two parts, but can also have more parts, ie, for example, have a third closing spring. The first closing spring is preferably arranged on an outer lateral surface of the first closing spring guide tube, in particular slipped onto the first closing spring guide tube. The second closing spring is preferably and at least in sections preferably arranged on the outer lateral surface of the first closing spring guide tube, preferably slipped on, and preferably and at least in sections preferably arranged on the outer lateral surface of the second closing spring guide tube, preferably slipped on. As a result, the second closing spring can be guided on an outer lateral surface of the second closing spring guide tube and/or on an outer lateral surface of the first closing spring guide tube. This advantageously prevents the second closing spring from buckling or buckling. If the first closing spring guide tube pushes over the second closing spring guide tube during the return movement of the locking device, the space between a base piece, which represents a rear housing boundary and preferably also a rear boundary of the second closing spring, and the spacer element becomes smaller and smaller. Since the second recoil spring is “floating” on the recoil spring guide tubes and can only be supported on the front on the spacer element and on the rear on the base piece, which is firmly connected to a housing viewed in the longitudinal direction, it is compressed in the process. The same preferably also applies to the first closing spring, which is supported at the front on a lock carrier and at the rear on the spacer element.

In terms of the magnitude of its initial force F1e, when the handgun is in the ready-to-fire basic position, the first recoil spring is preferably designed to be somewhat stronger than the initial force F1z of the second recoil spring. This ensures that the spacer element always remains in a defined position in its structurally specified position when the weapon is in the ready-to-fire basic position.

It is also advantageous that a stationary stop on the housing limits the longitudinal movement of the spacer element forwards approximately when the weapon is in the ready-to-fire basic position. A firing pin is usually anchored directly in the bolt carrier of the bolting device of a handgun. The firing pin can preferably be received directly or indirectly, for example via a second firing pin housing, at least in sections in a recoil spring guide tube, preferably in the first recoil spring guide tube. The second firing pin housing can be inserted without play into the recoil spring guide tube, preferably into the first recoil spring guide tube. The second firing pin housing can be integrally formed in and/or on the recoil spring guide tube.

The firing pin is usually made in one piece from a steel material. The firing pin typically has a firing pin tip, a firing pin body, one or more centering or support diameters, and a striking surface.

In one configuration, the firing pin can be designed as a light firing pin. Due to the design of the light firing pin, there is no need to install a firing pin safety without the risk that the firing pin moving forward during the closing movement of the forward-moving locking device can ignite the cartridge in the chamber in an uncontrolled manner. It is advantageous here that the handgun becomes less susceptible to faults as a result. There is also a cost advantage since the handgun has fewer components and can be manufactured more cheaply.

If a handgun is set up for a relatively long cartridge, for example, the firing pin must also be made long enough in order to be able to establish an operative connection between the hammer, which is usually located behind the cartridge magazine, and the cartridge to be fired in the barrel. As a result, the firing pin, which is made entirely of steel, is usually so heavy that it is already able to ignite the cartridge lying ready in the barrel or at least damage the primer of the waiting cartridge due to its own mass when the locking device is closed. A firing pin safety device is therefore usually installed in the breech mechanism in the case of firing pins which, due to their weight, are suitable for independently igniting a ready cartridge or at least for damaging the primer of a ready cartridge during the closing movement of the breech in order to be able to rule out this risk.

It is advantageous that the usable installation space for the recoil spring within the weapon housing can be significantly increased in the longitudinal direction, without lengthening the weapon housing itself, by dividing the one recoil spring usually installed in handguns according to the prior art into a first and at least one second Closing spring is done and the two closing spring elements are arranged separately by a spacer element. In this case, an additional installation space can be developed preferably in front of the effective range of a tap and/or as a first step ckungsraum be used for the first closing spring.

In one configuration of the closing spring device, the spacer element has an essentially cylindrical spacer element body with an essentially cylindrical spacer element jacket with an inner jacket surface and an outer jacket surface. The spacer element shell encloses a substantially cylindrical spacer element interior. The spacer element jacket preferably delimits the spacer element interior arranged in the direction of longitudinal extension. A first support surface is formed at a front end of the spacer shell and a second support surface is formed at a rear end of the spacer shell. A first end face is preferably formed on the front end of the spacer element casing. The spacer element jacket preferably has a second end face at its rear end. The design of the interior allows the spacer element to be mounted on the first closing spring guide tube so that it can be moved in the longitudinal direction along the central axis. The first closing spring can preferably be supported on the first support surface during a linear movement of the closing spring device, in particular the first closing spring. The at least second closing spring can be supported on the second support surface during a linear movement of the closing spring device. The interior space of the spacer element is preferably designed in such a way that the interior space can accommodate the first closing spring guide tube and/or the second closing spring guide tube. An inner diameter of the spacer element is preferably designed in such a way that the inner diameter is larger than an outer diameter of the first closing spring guide tube. The inner diameter is particularly preferably approximately 0.1 to 0.3 mm larger than the outer diameter in order to allow play in the linear movement.

The spacer element can be made of metal or plastic. If the spacer element is made of metal, for example, the interior space of the spacer element is produced by means of a bore through a solid cylinder, with the spacer element casing delimiting the interior space as an envelope. If the spacer element is made of plastic, a mold that reproduces the essentially cylindrical interior space of the spacer element can be used during production.

The spacer element has a first recess which extends from the inner surface of the jacket to the outer surface of the jacket, with the first recess preferably severing the jacket of the spacer element. In one embodiment of the spacer element, the first recess has an elongated hole shape, viewed in the longitudinal direction of the spacer element casing, the first recess having the elongated hole shape extending on the side of the spacer element facing the tap. The first recess is preferably delimited at the front by a first delimiting surface and the first delimiting surface is arranged at a distance from the first support surface, which preferably runs radially. Here, the first recess is preferably limited to the rear by the second boundary surface. The second boundary surface is arranged at a distance from the second support surface.

During the manufacture of the spacer element, the first recess can be milled out of the spacer element casing, so that the first recess severs the spacer element casing in the region of the first recess. If the spacer element is made of plastic, the first recess is taken into account, for example, in the manufacture of the injection mold.

During operation of the handgun, the hammer of the trigger can punch through the first recess in the spacer element and through a recess in the first recoil spring guide tube, reach the rear end of the firing pin and thus ignite a cartridge in the chamber. In this case, the first closing spring guide tube preferably also has a slot-shaped recess.

The spacer element preferably has at least one second recess. The second recess is formed in the inner surface of the casing, the second recess being formed essentially in the direction of longitudinal extent of the spacer element casing, in particular on the inner surface of the casing. Additional second recesses can be formed in the direction of longitudinal extent of the spacer element casing, in particular in or on the inner surface of the casing. If, for example, three second recesses are formed in the inner surface of the casing, each second recess runs parallel on the inner surface of the casing and is offset radially by approximately 60 degrees. All second recesses are preferably arranged equidistantly from one another. The second recesses are formed in such a way that the inner diameter of the spacer element is not reduced.

The at least one second recess is preferably designed as a groove in the inner surface of the casing. In particular, all other second recesses are each formed as a groove. In particular, all of the second recesses are formed in sections on the lateral inner surface of the spacer element. In particular, the second recesses only extend over a portion area of the inner surface of the jacket. The at least one second recess preferably forms at least one stop surface at the front end. The at least one stop surface is preferably designed in the form of ribs. The stop surface is formed in particular by the second recess, which does not extend over the entire inner wall surface. In one configuration, the spacer element has at least one section running radially outwards in the region of the rear end. It is advantageous here that the spacer element can be easily grasped by means of the at least one section during assembly and is easy to handle.

In one embodiment, a spacer element collar is formed at the rear end of the spacer element, with the spacer element collar running radially, in particular essentially perpendicularly, to the spacer element casing. The spacer element collar preferably has the second support surface. The second closing spring can be supported on the second support surface during a linear movement of the closing spring device. By means of the spacer element collar, the spacer element can be easily grasped and handled during assembly.

In one configuration, the spacer element collar has at least one first section. At least one second section is preferably provided, with the first section and the second section being arranged essentially offset by approximately 180° on the spacer element collar, in particular being arranged radially. As a result, the spacer element can be supported radially at least on an inner surface of the housing of the handgun. The spacer element can preferably be supported radially with respect to the outer surface of the jacket of the first closing spring guide tube. In particular, the spacer element is arranged by the spacer element collar and/or the first section and/or the second section in the ready-to-fire basic position of the locking device shortly before a stop in the housing, which is referred to as a housing-fixed stop, and during the closing movement of the locking device on the housing-fixed stop can be supported to the front.

The spacer element can preferably be supported radially with its spacer element collar at least on an inner surface of the housing. In one embodiment, the first closing spring guide tube can be supported on the bolt carrier via the spacer element body of the spacer element and/or via the spacer element collar or a partial area of the spacer element collar of the spacer element inside the housing. This is particularly advantageous since the head element of the first recoil spring guide tube is fastened on one side on or in the bolt carrier only in the front region. This can prevent the first recoil spring guide tube in the rear area, particularly in the area of the telescoping interface to the second recoil spring guide tube, from swinging open and/or buckling in the radial direction, particularly during the dynamics of the shot development, thereby interfering with the recoil of the locking device.

The spacer element collar of the spacer element preferably has a third and a fourth section, with the third and the fourth section each being arranged adjacent to the second section. The third section is preferably arranged on the right side and the fourth section on the left side of the second section. Thus, the third section and the fourth section are arranged symmetrically to the second section and a longitudinal axis of the spacer element collar.

In one embodiment, the front end of the first recoil spring can be supported on a bolt carrier of a locking device of the handgun or on a component that is firmly connected to the bolt carrier of a locking device of the handgun, at least in the longitudinal direction, in particular the recoil spring guide tube.

Preferably, the first closing spring can be supported with a rear closing spring end on the first preferably radially extending support surface on the spacer element. Furthermore, the second closing spring can be supported with a front closing spring end on the second, preferably radially extending support surface on the spacer element and/or with the rear closing spring end on a housing of the handgun and/or on a component which is firmly connected to the housing of a handgun at least in the longitudinal direction, such as for example a floor piece, supportable.

The first closing spring guide tube also has a slot-shaped recess, analogous to the first slot-shaped slot on the spacer element. The slot-shaped recess is also arranged in the ready-to-fire basic position of the weapon on the side of the first recoil spring guide tube facing a hammer. The slot-shaped recess is preferably on the first recoil spring guide tube in the ready-to-fire basic position of the handgun essentially congruent with the first slot-shaped recess on the spacer element.

The cocked hammer can in the ready-to-fire basic position of the weapon through this first recess with the slot-like shape on the spacer element, as well as through with this in Substantially congruently arranged oblong hole-shaped recess in the first recoil spring guide tube to reach the striking surface of a firing pin and push it forward to ignite a cartridge.

The firing pin is preferably supported in its rear region in a second firing pin housing, the second firing pin housing being introduced without play in the first recoil spring guide tube or being integrally formed directly in this. The second firing pin housing can limit the rearward movement of the firing pin and preferably guides the firing pin on the central axis of the handgun.

The linear movement of the firing pin backwards or forwards is preferably not completely limited. The firing pin is preferably not fully clamped in the longitudinal direction by the two stops. The firing pin can move at least a few millimeters in the longitudinal direction. In particular, the front area of the firing pin is mounted in a first firing pin housing. The first firing pin housing is preferably anchored without play, for example by means of a thread or preferably via a bayonet in the second firing pin housing. The first firing pin housing can also be anchored directly in the bolt carrier, preferably without play. The first firing pin housing can be separated from the second firing pin housing easily and particularly preferably without tools.

The first firing pin housing preferably limits the forward movement of the firing pin and guides the firing pin on the central axis of the handgun. If the first firing pin housing is separated from the second firing pin housing and/or the bolt carrier, the firing pin can be removed.

The spacer element is slipped onto the outer lateral surface of the first closing spring guide tube, the spacer element being movably mounted in the longitudinal direction on at least one outer surface of the first closing spring guide tube. When the handgun is in the ready-to-fire basic position, the spacer element is preferably pushed backwards by a force initiated by the first recoil spring, with the spacer element being pressed with its at least one stop surface of the at least one second recess against at least one lug, in particular a rib-shaped lug, on the first recoil spring guide tube, with the linear movement of the spacer element is limited to the rear relative to the recoil spring guide tube. The spacer element is advantageously permanently radially fixed relative to the first recoil spring guide tube and remains in this state in every operating state of the handgun.

The spacer element is preferably made of a light material, preferably made of a light metal and/or a plastic.

In the locking device with the closing spring device, the second firing pin housing and/or the first firing pin housing can preferably be connected directly to the bolt carrier.

The firing pin is preferably made entirely of steel. Due to the high density of 7.85 kg/dm3, the firing pin is relatively heavy. However, the firing pin is advantageously very wear-resistant.

The firing pin body of the firing pin can preferably be made easily, with the firing pin body being made from a light material, in particular a light metal and/or a light metal alloy and/or from a fiber-reinforced plastic, in particular GRP and/or CFRP, with wear-intensive areas of the firing pin, such as, for example, the firing pin tip and/or a rear firing pin surface and/or a centering sleeve are made of resistant and low-wear material, for example steel.

The object is also achieved by a handgun with a housing and a barrel, with a locking device and a closing spring device according to the invention being arranged in the housing. In one configuration, the recoil spring device with a first recoil spring guide tube, at least one second recoil spring guide tube, a first recoil spring and at least one second recoil spring is provided on a breech carrier of the breech block device along the central axis and viewed against the firing direction, with the spacer element being arranged on or on the first recoil spring guide tube , wherein the spacer element is arranged between the first closing spring and the second closing spring. In this case, a connection point between the bolt carrier and the closing spring device is positively locked within the weapon housing via a fixing bolt, preferably always positively locked. The connection point is preferably designed as a thread, but particularly preferably as a bayonet. The length / height that the fixing bolt protrudes upwards over the bolt carrier in the unlocked position ensures that the entire bolt can no longer be inserted into the weapon housing from behind. Therefore, the fixing bolt must preferably be outside the housing are first brought into its locking position for the first recoil spring guide tube, the second firing pin housing and the first firing pin housing in the bolt carrier. Only then is it located in the upper area of the bolt carrier within the contour of the bolt carrier and the entire bolt can be reinserted into the housing from behind.

The recoil spring device for a handgun is also referred to as a recoil spring assembly and has a spring guide device and a firing pin assembly, the spring guide device having a first recoil spring guide tube and at least one second recoil spring guide tube as well as a first recoil spring and at least one second recoil spring. A spacer element is provided, which is arranged between the first closing spring and the at least second closing spring. The spacer element is movable in the longitudinal direction relative to the first closing spring guide tube. The spacer element is preferably movably mounted in the longitudinal direction. The spacer element is preferably slipped onto the first closing spring guide tube. The spacer element is supported radially relative to the first closing spring guide tube.

A further advantage of using the closing spring device according to the invention is the smaller space requirement, the compact external dimensions and, as a result, a narrower silhouette of the handgun. This allows a lower line of sight to be realized. The handgun as a whole becomes much more manageable and can also be gripped better with one hand.

By arranging the recoil spring device on the central axis of the handgun and thus on the weapon barrel axis of the handgun, a through-loading device can be arranged in the upper area of the handgun. This is similar to, for example, the American M4 / M16 assault rifle. It is advantageous here that a very large number of shooters are familiar with such a through-loading device and can handle it with practice.

The recoil spring of the recoil spring device can be compressed by an axial movement of the bolt carrier, which is initiated, for example, by the recoil of the cartridge case or the propellant gas of the cartridge when the projectile is fired onto the bolt carrier. Due to the spring force, the bolt carrier and thus the entire bolt can be shifted forward axially.

The handgun with a housing and a barrel is characterized in that a locking device and a closing spring device according to the invention are arranged in the housing.

In one configuration of the handgun, the recoil spring device with the first recoil spring guide tube, the second recoil spring guide tube with the base piece and/or the rear limit, the first recoil spring, the second recoil spring and the spacer element is arranged on the breech carrier of the breech mechanism along the central axis and viewed against the firing direction , wherein the spacer element is arranged between the first recoil spring and the second recoil spring on or on the first recoil spring guide tube, the firing pin being attached directly in or on the bolt carrier.

In a further embodiment, individual components of the closure device and the closing spring device can be arranged in an alternative arrangement.

In the handgun, for example, the first recoil spring and the recoil spring device with the first recoil spring guide tube, the second recoil spring guide tube with the base piece and/or the rear boundary, the second recoil spring and the spacer element are arranged on the breech carrier of the breech block mechanism, viewed along the central axis and counter to the firing direction. the spacer element being arranged in front of the second recoil spring on or on the first recoil spring guide tube, the firing pin being fitted directly in or on the bolt carrier.

In the handgun, the recoil spring device with the first recoil spring guide tube, the second recoil spring guide tube with a base piece and/or rear boundary, a first recoil spring, a second recoil spring and a spacer element can be arranged on the breech carrier of the breech block mechanism along the central axis and viewed against the direction of fire, wherein arranged on or on the first recoil spring guide tube the spacer element is arranged between the first recoil spring and the second recoil spring, with a second firing pin housing preferably being accommodated at the front in the first inner area in the first recoil spring guide tube, with the firing pin being able to be locked with the first firing pin housing to form the closing spring device.

A fixing bolt with a head element and a fixing bolt body is preferably provided in the bolt carrier in the handgun, creating a connection point between the bolt carrier and the closing spring device inside half of the weapon housing is positively locked by means of the fixing bolt, preferably is always positively locked.

In the handgun, the fixing bolt on the fixing bolt body has a first latching position, a second latching position and a third latching position, wherein when the fixing bolt is pulled out of the bolt carrier into a third latching position, the recoil spring device can be completely removed from the bolt carrier, with the first firing pin housing and the Firing pin remains on the closing spring device.

In the handgun, the bolt head can be removed from the bolt device. In particular, the bolt head and the bolt carrier can be separated. When the fixing bolt is pulled out of the bolt carrier into the second detent position, the closing spring device will always remain locked to the bolt carrier, with the first firing pin housing and the firing pin being able to be removed from the closing spring device.

The design of the closing spring device is advantageous. Since the bolt carrier is rigidly connected to the first recoil spring guide tube, the second firing pin housing and the first firing pin housing, the weight of these three components can be added to the mass of the bolt carrier, i.e. in order to set the bolt function properly on the handgun, for physical reasons in relation to the Pulse of the cartridge necessary weight of the bolt carrier to be reduced by the weight of the first recoil spring guide tube, the second firing pin housing and the first firing pin housing and thus the handgun can be made lighter by this amount of weight.

At this point it is emphasized that, in addition to the previously described components of the locking device and the handgun, there are other components that are necessary for the function of the handgun and are not explicitly mentioned. These correspond to the components of a locking device and a handgun, as are described in the prior art. These are, for example, all components of a trigger mechanism without being explicitly mentioned.

In the description, the description of the figures and the claims, the terms "front", "rear", "top" and "bottom" are used in the known form and in relation to a handgun that is used in the usual way. This means that the muzzle of the barrel is “in front”, that the breech mechanism is moved backwards, especially by the explosive gases, etc. The axial direction means the direction of the barrel axis (barrel axis), which is typically along the central axis .

All features and advantages that are listed in connection with the recoil spring device also apply to the handgun, without being explicitly listed in the description of the handgun.

character description

The object of the invention is described in more detail below with reference to the objects shown in the figures. Identical objects are provided with the same reference symbols in the figures.

1a shows a handgun 10 seen obliquely from behind in an isometric, schematic representation. 1b shows the handgun 10 in side view. The designations “front” and “rear” as well as “in front” and “rear” are described below in the firing direction indicated by the arrow 12—referred to as firing direction 12 . A fired shot exits the front of the handgun 10.

The handgun 10 has a housing 14 which has an end cap 16 at its rear end. A trigger 20 is arranged on the housing 14 with a grip sleeve 18 on which a trigger guard 22 is attached. A fire selector lever 21 also projects out of the housing 14, preferably on the right and left side of the weapon housing. The trigger 20, a hammer 23 not shown, a hammer 25 not shown (both shown in 2a) and the fire selector lever 21 with a fire selector lever shaft 21' together form a trigger mechanism. Also arranged on the housing 14 is a magazine shaft 24 for receiving a magazine 26 with a magazine base 28. The housing 14 has an ejection window 32 on the left side (shown) and also on the right side (not shown), which is used for ejecting a cartridge case 63 is suitable after a shot is fired. Also, when the handgun 10 is unloaded, a cartridge 62 that has not yet been fired is generally ejected from the ejection port 32 . The ejection window 32 can be arranged both on the left and on the right side of the housing 14 . The housing 14 is preferably fabricated with an ejection port opening 32 on each side, with the unused ejection port 32 being plugged with a piece of material. Thus, the same housing 14 can be used for both right-handed and left-handed handguns 10.

A weapon barrel 34 , which is also referred to as the barrel 34 , is then arranged at a front end of the housing 15 seen in the firing direction 12 . The weapon barrel 34 is preferably designed as a cylindrical barrel 34 . The tube 34 is preferably torsionally rigid. The weapon barrel 34 is provided with a hand guard 38 in its partial section 36 facing the housing 14 . The hand guard 36 is here arranged around the weapon barrel 34 .

A fire control unit 40 , which can be designed as a fire control computer 40 , can be arranged geodetically above the housing 14 . Between the housing 14 and the fire control unit 40 is a load-through unit 42 or load-through mechanism 42 . The fire control unit 40 is mounted on a rail 17 or an alternative interface 17 or can also be attached directly to the weapon housing 14 . When the handgun 10 is fully assembled, the housing 14 has an in 1a and 1b locking device 44, not shown, and a closing spring device 55 are arranged.

2a shows the handgun 10 in a schematic representation in longitudinal section along the firing direction 12. The handgun 10 is loaded, the locking device 44 is locked (basic position), the cock 23 is cocked and the Handgun 10 is secured. A center line 5 runs in the longitudinal direction essentially parallel to the direction of fire 12. The center line 5 runs in the center of the weapon barrel 34 and the locking device 44 as well as the closing spring device 55 Hahn 23, which can be rearranged by the trigger 25. The fire selector shaft 21' of the fire selector 21 can release or lock the trigger 20.

In addition to the in 1 designated components of the handgun 10 are in 2a Individual parts of the closing spring device 55 and the locking device 44 can be seen. A cartridge 62 is shown in front of the locking device 44 . The locking device 44 has a locking head 46 , a locking carrier 48 , a spring-loaded locking bolt 52 , a spring-loaded locking pin 66 , a plug 67 and a closing spring device 55 . The bolt head 46 is arranged in front of the bolt carrier 48 . The spring-loaded detent pin 52 is located at the bottom in the breech carrier 48 and lies essentially transversely to the central axis 5 . A locking piece 68 is arranged in front of the locking device 44 . A cartridge ladder 70 can be seen below the breech head 46 . The closing spring device 55 has a first closing spring 59 and a second closing spring 61 . A spacer element 57 is arranged between the first closing spring 59 and the second closing spring 61 . The closing spring device 55 is as a closing spring assembly 55 in the 3 and 4 Shown individually and it is added to the description 3 and 4 referred.

2 B shows a schematic representation of a section of the handgun from 2a in sectional view. The locking device 44 with the attached closing spring device 55 is shown in the basic position, with the hammer 23 being cocked. In addition to the components in the 1a , 1 b and 2a 1, a locating bolt 72 disposed in bolt carrier 48 is shown. The fixing bolt 72 has a fixing bolt head 71 and a fixing bolt body 73 of essentially cylindrical shape.

2c shows another section of the handgun 10. In addition to the 1 , 2a and 2 B The objects illustrated show a first firing pin housing 51a and a second firing pin housing 51b. Furthermore, a first locking position 72a, a second locking position 72b and a third locking position 72c can be seen on the fixing bolt 72 . The locking pin 66 is locked in the first locking position 72a.

2d shows the closure device 44 with the closing spring device 55 attached 2c further enlarged. The trigger 25 and the position of the locking groove 23a on the hammer 23 can be seen.

2e shows the handgun 10 unlocked. Cock 23 has been knocked off. It can be seen that the hammer 23 has passed through a slot-shaped recess 106 in a spacer element jacket 100 of the spacer element 57 and through a slot-shaped recess 144 in the first closing spring guide tube 56 . Firing pin 50 is in firing position.

2f shows a section of the handgun 10 in longitudinal section. The closure device 44 is slightly open. The hammer 23 is being cocked by a front boundary 145 of the slot-shaped recess 144 in the recoil spring guide tube 56 and a rear edge at the bottom of the bolt carrier 48. The hammer 23 is located in the first recess 106 of the spacer element 57. The first recoil spring guide tube 56 has, since the closure device 44 has moved backwards, already pushed somewhat over the second recoil spring guide tube 58 . The first recoil spring guide tube 56 and the second recoil spring guide tube 58 are somewhat telescoped. The shoulder 118 of the second recess 116 of the spacer element 57 has moved away from a stop surface on the rib-shaped nose 142 on the first closing spring guide tube 56 . The spacer element 57 is shifted in the direction of the bolt carrier 48 and “penetrated” into it. The first closing spring 59 is somewhat compressed and the second closing spring 61 as well. A stop edge 147 fixed to the housing for the spacer element 57 is now clearly visible.

2g shows the handgun 10 in a schematic representation in longitudinal section. The locking device 44 is shown in the rear end position on the locking buffer, which is not shown. The first closing spring 59 and the second closing spring 61 are maximally prestressed. The first closing spring guide tube 56 is pushed over the second closing spring guide tube 58 . The spacer element 57 is pushed into the bolt carrier 48 as far as possible. The first recoil spring guide tube 56 sits over a second recoil spring guide tube 58 (telescope collapsed). The second barrel spring guide tube 58 is stationary connected to the housing 14 or is supported on the housing 14 to the rear. The hammer 23 is cocked. Thus, the closure device 44 and the Closing spring device 55 at the rear reversal point.

3a shows the closure device 44 with the closing spring device 55 in an isometric representation. The locking device 55 has the locking head 46 and the locking carrier 48 . The closure head 46 has at least one first control lug 78 in a front area 76 . At least one second control knob 82 is arranged in a rear row 80 . The lock carrier 48 has at least one recess 84 at a front end 86 of the lock carrier 48, with which the at least one second control lug 82 can come into operative connection.

The spacer element 57 and the second closing spring 61 and the first closing spring guide tube 56 and the second closing spring guide tube 58 can be seen. The second closing spring guide tube 58 is connected to the end cap 16, preferably permanently connected. The second closing spring 61 is preferably also supported on the end cap 16 .

3b shows the lock carrier 48 of the locking device 44 with the closing spring device 55 according to FIG 3a , with the bolt head 46 removed. The firing pin tip 50a of the firing pin 50 and the first firing pin housing 51a can be seen.

3c shows the lock carrier 48 with the closing spring device 55 according to FIG 3b , the fixing pin 72 in the second detent position 72b, whereby the forced locking of the first firing pin housing 51a is released, the first firing pin housing 51a being twisted out of its bayonet lock 148 and thus released and being shown on the left-hand edge of the figure.

3d shows the lock carrier 48 with the closing spring device 55 according to FIG 3c , wherein the firing pin 50 is removed. A part of the bayonet lock 148 in the second firing pin housing 51b, in which the first firing pin housing 51a in 3b is recorded. In the 3c the first firing pin housing 51a is removed.

In 3e is the lock carrier 48 with the closing spring device 55 according to FIG 3d shown in half section. The spring-loaded locking pin 66 is locked in the fixing bolt 72 in the second locking position 72b.

In 4a the closure device 44 with the closing spring device 55 is shown in half section. The fixing bolt 72 is locked in the first locking position 72a. In this state, the locking device 44 with the attached closing spring device 55 can be inserted from behind into the weapon housing 14 and brought into the basic position in the handgun 10 ready to fire.

In 4b is the locking device 44 with the closing spring device 55 according to FIG 4a shown. The fixing bolt 72 is locked in the third locking position 72c. In this state, the locking device 44 with the attached locking spring device 55 can no longer be inserted from the rear into the weapon housing 14 and brought into the ready-to-fire basic position in the handgun 10, since the fixing bolt head 71 of the fixing bolt 72 protrudes over the top edge of the bolt carrier 48 and therefore when inserting the locking device 44 into the weapon housing 14 would prevent the insertion. The same applies when the fixing bolt 72 is latched in the second latching position 72b.

In 4c is the locking device 44 with the closing spring device 55 according to FIG 4b shown in side view. Here, the closure device 44 is shown in the upper part of the figure and the closing spring device 55 underneath. The closing spring device 55 has been removed from the closing device 44 . A head part 88 arranged on the first closing spring guide tube 56 can be seen with a head part collar 90 and a substantially cylindrical head part body 92. Locking elements 95 are formed on the front end 94 of the head part body 92, which are used for locking, in particular a bayonet locking with the locking device 44.

In 4d is the locking device 44 with the closing spring device 55 according to FIG 4c shown in isometric view. The head element 88 with the head element collar 90 and the essentially cylindrical head part body 92 is arranged on the front end of the first closing spring guide tube 56 . The head element 88 is connected to the first closing spring guide tube 56, in particular firmly connected, particularly preferably integrally formed on the first closing spring guide tube 56.

In 4e is the locking device 44 with the closing spring device 55 according to FIG 4d is shown with the first firing pin housing 51a removed.

In 4f is the locking device 44 with the closing spring device 55 according to FIG 4e shown with firing pin 50 removed.

In 4g the closing spring device 55 is shown in a schematic representation in a perspective representation from the rear bottom to the front.

In 5a the spacer element 57 is shown schematically in an isometric representation in a simple embodiment. In 5b is the spacer element 57 according to 5a shown in half section from left. The description thus refers to the 5a and 5b . The spacer element 57 is an essentially cylindrical spacer element body 96 which has an essentially cylindrical spacer element interior 98 . The spacer element body 96 is essentially designed as a hollow cylinder 96 . The spacer element interior 98 is enclosed by a spacer element jacket 100 . The spacer element jacket 100 has an inner jacket surface 102 and an outer jacket surface 104 . The spacer element interior 98 can be produced, for example, from a cylindrical solid material body through a central bore. The spacer jacket 100 has a thickness d and a length L. The thickness d can be non-uniform. The wall thickness of the spacer element jacket 100 is reduced in particular in the area of the second recesses 116 .

At least one first in 5a recess 106 shown only in sections, which extends essentially in the form of a slot in the spacer element casing 100, in particular along the length L at least in sections in the spacer element casing 100. The first recess 106 cuts through the spacer element casing 100 in sections. A slot-shaped recess 106 is thus arranged in the spacer element casing 100 , the slot 106 extending along the spacer element casing 100 and essentially parallel to the central axis 5 . The function of the first recess 106 is to allow the tap 23 to pass through the spacer shell 100 . When the handgun 10 is installed and in the ready-to-fire basic position, the first recess 106 is arranged on a side of the spacer element 57 that is assigned to the hammer 23 . The first recess 106 has a first step 110 or a support surface 110 at a front end 108 . Furthermore, the first recess 106 has a second shoulder 112 at a rear end 114 opposite the first shoulder 110 of the recess 106 .

At least one second recess 116 is provided. A total of three second recesses 116a, 116b and 116c are shown. The second recesses 116, 116a, 116b, 116c are typically designed in the form of grooves in the inner wall 102 of the jacket. The second recesses 116, 116a, 116b and 116c only partially extend in the inner wall 102 of the casing and each form a stop surface 118, 118a, 118b, 118c. The second recesses 116, 116a, 116b and 116c are arranged at a distance from one another. The length L' of the second recesses 116, 116a, 116b and 116c is less than the length L of the spacer element jacket 100.

A first support surface 120 is formed at the front end 108 of the spacer element 57 and a second support surface 122 is formed at the rear end 114 . The first shoulder 110 is spaced from the first support surface 120 . The second shoulder 112 is spaced from the second support surface 122 .

5c shows the spacer element 57 with a spacer element collar 124 in an isometric view. The spacer element collar 124 is arranged at the rear end 114 of the spacer element casing 100 and extends essentially perpendicularly to the spacer element casing 100.

5d shows the spacer element 57 of FIG 5c in half section from the left. The spacer collar 124 has the second support surface 122 . The second support surface 122 is delimited by a rib-shaped shoulder 126 which is arranged in a cylindrical manner around the support surface 122 and essentially radially encloses it.
The second support surface 122 on the spacer element collar 124 is thus recessed in the spacer element collar 124 to save space, whereby the installation space for the second recoil spring 61 can be retained in the firing direction 12 or in the direction of the front recoil spring end 61' and/or the length of the weapon housing 14 can be retained with the same length of the second closing spring 61 can be maintained at the rear. The spacer element collar 124 thus has a sufficient length b to keep the structure of the spacer element collar 124 sufficiently stable in the longitudinal direction.

At least a first collar section 128 and preferably a second collar section 130 is formed on the spacer element collar 124 . The first collar portion 128 and the second collar portion 130 are disposed substantially opposite each other. The first collar section 128 is preferably arranged at the top of the spacer collar 124 . A further collar section 132 and 134 is arranged on each side of the second collar section 130 . The collar sections 128 and/or the collar section 130 have the function of supporting the spacer element 57 radially, in particular of supporting it against the housing 14 . The collar portions 128 and 130 are disposed radially outward. The sections 128 and 130 are designed as rib-shaped sections.

The sections 128, 130, 132, 134 on the outer edge of the spacer element collar 124, 126 are geometrically designed in such a way that the locking device 44 with the attached closing spring device 55 can be moved with slight play between the outer edge of the spacer element collar 124, 126 and the inner lateral surface of a housing 14 in the latter can be introduced into a housing structure 14 in a radially predetermined functional position. The radial position of the spacer element 57 is thus predetermined within the structure of the housing 14, also referred to as the weapon housing structure 14, at any point in time t.

The structure of the spacer element collar 124 is designed to keep it sufficiently stable in the longitudinal direction. This is particularly important if the spacer element 57 with at least a partial area of the spacer element collar 124, such as the second collar section 130, during the closing movement of the closure device 44 runs onto a stop edge 147 fixed to the housing or a stop surface 147 fixed to the housing, thereby limiting the forward movement of the spacer element 57 becomes. The stop edge 147 fixed to the housing or the stop surface 147 fixed to the housing is particularly preferably attached to the housing shortly before the spacer element collar 124 of the spacer element 57 when the locking device 44 is in its basic position ready to fire. This means that during the closing movement of the closure device 44, the spacer element 57 cannot swing forward against the spring force of the first closing spring 59, but the forward movement of the spacer element 57 is limited to the front by the stop edge 147 fixed to the housing or the stop surface 147 fixed to the housing.

Furthermore, it is particularly preferred to support the first recoil spring guide tube 56 in its central section 140 via the spacer element 57 on the inner geometry of the weapon housing 14 via a sufficiently stable structure of the spacer element collar 124 . This has the great advantage that the first recoil spring guide tube 56, otherwise only accommodated on one side on the head part 88 in the breech carrier 48, cannot swing open in the rear area during the shot development and cannot interfere with the proper backwards movement of the breech mechanism 44.

The spacer element collar 124 can be particularly preferably integrally formed on the spacer element jacket 100 all the way around or only partially.

For example, further bores and/or recesses can be arranged in the second support surface 122 of the spacer element collar 124 and/or in the spacer element jacket 100 in order to be able to carry out the weight of the spacer element 57 more lightly.

6a shows a detail of the first closing spring guide tube 56 in a view obliquely from below. The closing spring guide tube 56 has thickenings or rib-shaped lugs 142, 142a, 142b, 142c, in particular lug-shaped shoulders 142, 142a, 142b, 142c in a central region. A recess 144 in the form of a slot is formed in the area of the middle section 140 , the dimensions of which essentially correspond to the dimensions of the first recess 106 in the spacer element 57 . In the ready-to-fire basic position of the locking device 44 of the handgun 10 ( 2a until 2d ) the two recesses 106 and 144 are arranged substantially congruently. The slotted holes 106 and 144 are arranged opposite the hammer 23 so that the hammer 23 can pass through the slotted holes 106 and 144 when the handgun 10 is in operation and can reach a firing pin 50, 50d.

The removed hammer 23 can be moved—at least partially—from its vertical ignition position to its horizontal, ready-to-fire position ( 2f) .

6b shows the first closing spring guide tube 56 in plan view. The at least one thickening or rib-shaped lug 142, 142a, 142b, 142c can be seen in the central area 140, which serves as a stop for the spacer element 57 to the rear when the weapon 10 is in the basic position ready to fire. A head part collar 90 is arranged in the area of the head part 88 of the first closing spring guide tube 56 . The head part collar 90 is supported at the front directly on the closure carrier 48 of the closure device 44 . The bolt carrier 48 can push the first recoil spring guide tube 56 backwards via the head part collar 90 during the opening movement and the rearward movement of the closure device 44 against the firing direction 12 and thus reduce the installation space for the recoil spring 60, 59, 61. The head-part body 92 extends in front of the head-part collar 90 and has an essentially cylindrical outer lateral surface. The first recoil spring guide tube 56 is received and supported in an appropriate bore in the bolt carrier 48 via the header body 92 .

At the front of the head part body 92, the locking elements 95, 95a, 95b partially extend radially outwards. These are part of a bayonet lock and are used to connect the first recoil spring guide tube 56 and thus the recoil spring device 55 to the bolt carrier 48 in to connect longitudinally. A locking hole 146 extends at the top approximately in the middle of the head part body 92. This locking hole 146 is penetrated by the fixing bolt body 73 of the fixing bolt 72 when the fixing bolt 72 is in the first locking position 72a or in the second locking position 72b. If the fixing bolt 72 is in the third detent position 72c, the fixing bolt body 73 has left the area of the locking bore 146 . The first recoil spring guide tube 56 and thus the recoil spring device 55 can then be rotated out of their bayonet locking in the breech carrier 48 and removed from the breech carrier 48 .

7a 12 shows the firing pin 500 of the prior art. Prior art firing pins 500 are machined in one piece from steel.

7b shows the firing pin 50 according to the invention as a hybrid component. The firing pin 50 according to the invention has a lower weight than a firing pin 500 according to the prior art. Firing pin body 50b can be seen, which is made of a light material, for example a light metal and/or a light metal alloy and/or a fiber composite material such as CFRP or GFRP. Wear-intensive areas, such as the firing pin tip 50a and/or the striking surface 50d and/or one or more centering sleeves 50c are made of a wear-resistant material, such as steel. The reduced weight of the firing pin 50 according to the invention can ensure that the firing pin 50 cannot independently ignite the cartridge 62 in the weapon barrel 34 during the closing movement of the locking device 44 due to its own weight. The installation of a firing pin safety device in the handgun 10 can therefore be dispensed with. The handgun 10 can thus be made more cost-effective and less vulnerable.

The handgun 10 with the housing 14 or the housing structure 14 accommodates a support plate 16 or a base piece 16 in the rear area, which closes off the housing inner structure 14 to the rear. This support plate 16 or the base piece 16 can also be connected to an end cap 16 . This support plate 16 or a base piece 16 or an end cap 16 is preferably connected directly to the second closing spring guide tube 58 and thus to the closing spring device 55, so that the rear closing spring end 61" of the second closing spring 61 can contact the support plate 16 or the base piece at any time t 16 or on the end cap 16 can be supported.

The handgun 10 with the housing 14 or the housing structure 14 accommodates the locking device 44 in an interior space, preferably with the closing spring device 55 attached. The locking device 44 with the locking spring device 55 is stored in the housing 14 in the ready-to-fire basic position and when the handgun 14 is in operation, and the locking device 44 with the locking spring device 55 is guided.

The operation of the handgun 10 is described below. The various operational phases in a cycle from the primed position, in which the cartridge 62 is fed and the bolt 44 is locked, to when the cartridge 62 is fed again and the bolt 44 is locked, are summarized and explained as follows.

initial position

• • Cartridge 62 is fed and its front stop surface is in contact with the appropriate stop in chamber 64,
• • Due to the compressive force of the recoil spring 59, 60, 61 acting on the bolt carrier 48, the impact bottom surface 79 of the bolt head 46 rests against the cartridge case 63 of the cartridge 62 at the rear,
• • The bolt carrier 48 rests with its lower surface on the uppermost cartridge 62 in the magazine 26 and presses it down against a follower (not shown) and a magazine spring (not shown),
• • The breaker pawl (not shown) or catch catch (not shown) was pushed out of the effective range with the hammer 23 by the bolt carrier 48, so the catch catch (not shown) no longer puts the hammer 23 behind,
• • The hammer 23 is cocked and is only moved behind the trigger 25 in the locking groove 23a.

shot initiation

• • Der Abzug 20 wird gezogen,
• • Der Abzug 20 drückt dabei im hinteren Bereich den Abzughebel 25 nach oben
• • Der Abzughebel 25 bewegt sich dadurch im vorderen Bereich aus der Rastnut 23a am Hahn 23 nach unten und gibt somit den federbelasteten Hahn 23 frei,
• • Der Hahn 23 setzt sich in Bewegung,
• • Der Hahn 23 schlägt durch die erste Ausnehmung 106 im Distanzelementmantel 100 des Distanzelements 57 hindurch,
• • Hat der Hahn 23 den Distanzelementmantel 100 durchdrungen, schlägt er ebenfalls durch die langlochförmige Ausnehmung 144 im ersten Schließfederführungsrohr 56 hindurch und trifft dann auf die hintere Schlagfläche 50d des Schlagbolzens 50,
• • Der Schlagbolzen 50 bewegt sich nach vorne und dringt mit seiner Spitze 50a ins Zündhütchen der Patrone 62 ein,
• • Der Schuss bricht,
• • Das Treibladungspulver wird gezündet und dehnt sich sehr stark aus.

To fire the weapon 10, the following steps are carried out, in particular one after the other:

• • The trigger 20 is pulled,
• • The trigger 20 pushes the trigger lever 25 upwards in the rear area
• • As a result, the trigger 25 moves downwards in the front area out of the locking groove 23a on the hammer 23 and thus releases the spring-loaded hammer 23,
• • The cock 23 starts to move,
• • The tap 23 punches through the first recess 106 in the spacer element jacket 100 of the spacer element 57,
• • Once the hammer 23 has penetrated the spacer element shell 100, it also strikes through the slot-shaped recess 144 in the first recoil spring guide tube 56 and then hits the rear impact surface 50d of the firing pin 50,
• • The firing pin 50 moves forward and penetrates the cartridge primer 62 with its point 50a,
• • the shot breaks,
• • The propellant powder is ignited and expands greatly.

shutter opening process

• • The projectile is pushed out of the cartridge case 63 into the barrel 34 by the propellant gas,
• • The propellant charge exerts a force that is also directed backwards via the cartridge case 63, in the direction of the base of the bolt head 46,
• • The propellant charge exerts a force directed backwards onto the bolt carrier 48 via the cartridge case 63 and the bolt head 46 or via a gas piston system.
• • The breech 44 with its breech carrier 48 and breech head 46 is opened
• The first recoil spring guide tube 56 with the second firing pin housing 51b, the firing pin 50 and the first firing pin housing 51a, which is firmly connected to the slide carrier 48 of the slide 44, runs backwards together with the slide carrier 48 of the slide 44 against the firing direction 12.
• • By moving the slide carrier 48 backwards, a spring-loaded interrupter pawl (not shown) is released and the hammer 23 is released via the striking surface 50d of the firing pin 50, the second firing pin housing 51b, the front boundary surface 145 in the recoil spring guide tube 56 and the rear, lower edge on the Bolt carrier 48 cocked.
• • The trigger 25 and the interrupter pawl (not shown) can thus set the hammer 23, 23a back again.
• • The movement of bolt carrier 48 to the rear partially reduces the first recoil spring area of recoil spring 59 and the second recoil spring area of recoil spring 61 and thus the first recoil spring 59, 60 as well as the second recoil spring 61 via the spacer element 57 floating forward in the axial direction 5 , 60 more and more compressed.
• • The overlapping of the first recess 106 of the spacer element 57 with the adequate recess 144 in the first recoil spring guide tube 56 is canceled further and further as the breech 44 returns, analogous to the change in length of the first recoil spring 59, 60.
• • The at least one shoulder 118, 118a, 118b, 118c in the spacer element 57 moves further and further away from the at least one adequate contact surface on the rib-shaped nose 142, 142a, 142b, 142c on the first closing spring guide tube 56.

Ejection of the empty case

• • The breech 44 runs further to the rear with the sleeve 63 and always preloads the closing spring 59, 60, 61,
• • The empty cartridge case 63 is pulled on the opposite side of the ejection window 32 by the locking device 44 onto a housing-fixed or swiveled-in or spring-loaded stop (not shown),
• • The case 63 of the cartridge 62 is abruptly stopped at this point by
• • On the side of the ejection window 32, the spring-loaded extractor 81 attached to the bolt head 46 pulls the sleeve 63 further backwards,
• • This initiates a lateral turning or tilting movement of the sleeve 63 in the direction of the ejection window 32,
• • The case 63 detaches from the bolt head 46 and the extractor 81 and is ejected in such a way that
• • As soon as the breech mechanism 44 leaves the area above the magazine 26, the uppermost cartridge 62 in the magazine 26, which was previously blocked by the underside of the breech carrier 48, jumps up in the magazine 26 by a pretensioned magazine spring underneath and rests against the magazine lips of the magazine 26,
• • This top cartridge 62 in the magazine 26 is thus ready for delivery.

Another shutter return

• • The locking device 44 runs further backwards,
• • The bolt carrier 48 strikes the base piece 16 or a bolt buffer,
• • The bolt carrier 48 and thus the bolt 44 is braked down to a standstill and is moved forward again by the force of the fully pretensioned closing spring 59, 60, 61.

Shutter advance

• • The front of the bolt head 46 hits the rear of the cartridge 62 in the uppermost position in the magazine 26 in the 6 o'clock area.
• • This is pushed by the bolt head 46 out of the magazine 26 over the ascent ramp 70 in the direction of the cartridge chamber 64,
• • The locking device 44 runs over the magazine 26 and places behind the following cartridge 62 jumping up in the magazine 26,
• • The upward movement of the bouncing cartridge 62 is limited by the underside of the bolt carrier 48.

locking the breech

• • The breech head 46 of the breech 44 then locks the rear end 19 of the weapon barrel 34 and thus supports the sleeve 63 of the cartridge 62 in the cartridge chamber 64 to the rear.
• • A stop 147 is preferably attached in the area of the housing 14 or the grip 18 or in the area of the receiving structure for a trigger mechanism 20, 22, 23, 25, which stops the movement of the spacer element 57 from the functional position of the spacer element 57 in the basic position of the weapon 10 limited to the front. In this way, it can be ensured when the closure 44 is locked that the spacer element 57 quickly comes to rest in the functionally correct position and does not first move a few times between the closing spring areas 59 and 61 of the closing spring 60 and/or the closing spring 59 and the rib-shaped nose 142. and swings here.
• • The first recess 106 of the spacer element 57 is again above the effective range of the hammer 23 and is also aligned with the appropriate recess 144 in the first recoil spring guide tube 56.
• • In order to effectively prevent an uncontrolled rebounding or bouncing of the breech 44, a recoil or rebound mass can preferably be placed in the breech carrier 48 or in the area of the first recoil spring guide tube 56.

initial position

• • The breech 44 is again in the ready-to-fire basic position of the handgun 10
• • As long as the handgun 10 is not fired, the breech 44 is held in this position by the spring force of the recoil spring 59, 60, 61
• • The handgun 10 is loaded with a new cartridge 62 and is therefore ready for use again.
