State of the art

A firearm or handgun is a device in which a ballistic projectile is propelled using very rapidly expanding hot gases called propellant gases. The firearm typically has a barrel and a housing, with the housing being disposed wholly or partially behind the barrel. The barrel has at its rear end a cartridge chamber for receiving a cartridge and an outlet opening for a projectile of the cartridge arranged in front of the cartridge chamber. The housing typically has a locking 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 on other functions, such as loading, firing, securing and unloading the firearm.

There are different locking devices for firearms known in the art, such as a tilt-loading lock, a block lock, a cylinder lock, a knee joint lock and/or a support flap lock. A Browning locking system, a ground lock and/or a roller lock, a lock driven by the tapped propellant gas and a gas-braked lock are known, particularly for semi-automatic firearms. With the mass closure, the mass of the mass closure is set in relation to the strength of the cartridge used in order to ensure the closure function. Here, the mass is typically designed in such a way that a safe shot is guaranteed, with the gas pressure acting backwards on the breech being sufficient to at least carry out the process of ejecting the cartridge case of the fired cartridge. In general, the cocking of a hammer of a firearm's trigger system and the reloading of the firearm with a new cartridge are also carried out. This is called repeating. Control of the closure device is achieved in particular via the inertia of the closure.

A further development of a ground closure is the roller closure, which from a structural point of view is a redirected ground closure. Rigid, i.e. locked systems, and semi-rigid systems are known here. For example, the Swiss Army's 57 assault rifle, the G3 rifle and the MP5 submachine gun from Heckler & Koch use roller shutters.

The publication DE 102 29 846 B3 discloses a locked machine gun with a housing, a barrel, a lockable breech with at least one locking body, an abutment for receiving the one or more locking bodies of the locked breech and a quick-change device for removing the barrel and attaching a new barrel, i.e. for changing the barrel, wherein a first part of the abutment remains on the housing when changing the barrel, a second part of the abutment is firmly connected to the barrel, and the quick-change device is set up to cause a separation between the first part of the abutment remaining in the housing and the barrel with the second part , and wherein the second part of the abutment has a curved piece which controls its engagement in the abutment when the closure is closed in order to make an interchangeable barrel cost-effective.

The publication US 2017/0074609 A1 discloses a breech for a semi-automatic or automatic weapon, comprising a breech receiving a cartridge, a barrel extension aligned with and extending outwardly from the breech, the barrel extension having a through hole aligned with the breech and an internal thread, a elongated bolt having an external thread complementary to the internal thread in the bore of the barrel extension, and a bolt carrier longitudinally displaceable and locked against rotation on the barrel extension, the bolt carrier being connected to the bolt to accommodate the bolt in accordance with to move the bolt carrier in the longitudinal direction and thereby enable rotation of the bolt relative to the bolt carrier.

Presentation of the invention task, solution, advantages

It is the object of the invention to provide an improved locking device for a handgun.

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

For a device of the type mentioned at the outset, this object is achieved according to the invention in that the first control device with the at least one control cam is arranged at the front end of the closure head and the second control device with the at least one control cam is arranged behind it, and the at least one control cam of the second control device is operatively connected to the closure carrier, the closure head being formed in one piece with the first control device and the second control device, the at least one control cam of the second control device having a control surface which is designed as an inclined surface with an inclination, and the inclination of the first as an inclined surface designed first control surface and the inclination of the second second control surface designed as an inclined surface are arranged in opposite directions relative to a normal to the central axis, and wherein the closure head has a rear boundary surface, the closure carrier has a front end face, wherein the at least one control lug with the rear boundary surface forms the closure carrier supported on the front end.

For a handgun, this task is achieved according to the invention by integrating the locking device according to the invention.

Advantageous embodiments of the locking device and the handgun can be found in the dependent claims.

The locking device for installation in a housing of a handgun has a locking head and a locking carrier, the locking head being arranged in front of the locking carrier, the locking head having a first control device and a second control device, the first control device having at least one control lug and the second control device at least have a control cam, wherein the first control device with the at least one control cam is arranged at the front end of the closure head and the second control device with the at least one control cam of the closure head is arranged behind it on the closure head, the at least one control cam of the second control device being in operative connection with the closure carrier stands. The closure device is characterized in that the closure head is formed in one piece with the first control device and the second control device. In particular, the control cam of the second control device is in operative connection with a control flank of the closure carrier. The control edge of the The closure carrier is preferably arranged on a side facing the closure head, in particular on a front side of the closure carrier. The control cam can be supported on a side of the bolt carrier that faces the bolt head.

In one embodiment, the first control device with the at least one control cam is arranged in the first row on the closure head and the second control device with the at least one control cam is arranged in the second row on the closure head. The first row is preferably arranged in front of the second row. Here, the first row and the second row are preferably arranged at the front region of the closure head. The first row is particularly preferably arranged directly in front of the second row.

Preferably, the first control device with the at least one control cam and the second control device with the at least one control cam are arranged directly one behind the other. This can counteract torsion or twisting of the structure of the closure head under load. In particular, it can be ensured that a shaft of the locking head, the locking head shaft, cannot twist or twist under load. This means that a significantly longer service life of the closure head component can be achieved. The at least one control cam of the second control device is preferably arranged at a distance from the at least one control cam of the first control device. The distance is preferably small.

By arranging the at least one control cam of the second control device in a second row behind the first control device, the control cam of the second control device can rest with its oblique control surface without play on the associated oblique control flank on the bolt carrier when the handgun is in the basic position ready to fire. As a result, the closure carrier can be pushed away from the closure head by the movement of the closure head. The lock carrier can in particular be pushed backwards.

In one embodiment of the closure device, the closure head is formed in one piece with the at least one control cam of the first control device and the at least one control cam of the second control device. In particular, the at least one control cam of the first control device and the at least one control cam of the second control device are formed on the closure head. As a result, the closure head can be manufactured easily and cost-effectively with the at least one control cam of the first control device and the at least one control cam of the second control device. For example, the closure head can be manufactured in one piece as a milled part with the control lugs of the first control device and the second control device.

In one embodiment of the closure device, the closure head and the closure carrier are arranged axially one behind the other along a central axis of the closure device, whereby both the closure head and the closure carrier can be displaced along the central axis in the event of an axial impulse on the closure head. The axial displacement of the closure head can have a different amount than the axial displacement of the closure carrier. The axial displacement is preferably decoupled.

In a further embodiment of the closure device, the closure head is arranged at least in sections within the closure carrier, a distance A, A 'being adjustable and the relative axial position of the closure head and the closure carrier to one another being changeable. Although the closure head and the closure carrier are preferably axially displaceable relative to one another, they always remain in operative connection. This is achieved in that the control cam of the second control device can be supported on a front side of the lock carrier.

The closure head can have partial elements, which are referred to as partial sections, which protrude into the closure carrier and/or are movable therein. The closure head preferably has a first section and at least a second section. The first section is preferably a front section which is arranged on the side of the closure head facing away from the closure carrier. The second section preferably has a closure head shaft. The second section can be received in the locking carrier when the locking device is in the locked state. In an unlocked state, the second section can protrude at least in sections from the lock carrier. During an unlocking process, the locking carrier can preferably move counter to the firing direction of the handgun, in particular move backwards. The second section is preferably moved out of the closure carrier. In the unlocked state, the second section is arranged in sections between the first section of the locking head and the locking carrier. The locking head shaft can be arranged on the second section.

In connection with the claims, active connection means a mechanical effect connection understood. The active connection is preferably an interaction between two components and/or surfaces and/or flanks and/or edges, in which one component influences the other - as specified by the design. The control cam acts as the first component and forms a mechanical pairing with a control flank assigned to it, which can function as a second component. This can be the pairing between the control cam and a control flank on the bolt carrier. Here, the control flank on the bolt carrier essentially coincides with an associated control surface of the control cam; it is not a point or line system, but preferably a surface system. This has the advantage that large forces can be transmitted and possible wear can still be kept within limits. The control flank on the lock carrier is aligned, at least in sections, essentially parallel to the associated control surface of the control cam. Preferably, a movement of the control cam and/or the closure carrier can be initiated and/or stopped by the interaction of the control cam and the associated control flank on the lock carrier. As a result, the control flank is preferably open towards the front on the side facing the closure head. The control cam is arranged on the bolt head and thus a movement of the bolt carrier can be initiated. Through the interaction of the control cam and the associated control flank on the bolt carrier, the movement of the bolt head and/or the bolt carrier can be positively guided. Here, further control elements, in particular stop surfaces or grooves, can restrict, preferably restrict, the movement, in particular the direction of movement of the closure carrier and/or the closure head.

The locking weapon device can be a firearm locking device. The closure device is in particular an improved translated mass closure. The advantage here is that the closure device is simple and robust. Furthermore, the closure device can have a few components, in particular the closure device does not have a control bolt. The locking device is free of control pins. The function of the control bolt, as used in handguns according to the prior art, is in the locking device according to the invention through at least the front control cam and / or in particular the interaction between control cams with inclined and parallel surfaces and the associated control flanks on the locking carrier and / or the locking piece and/or in the housing.

The control bolt is used in locking devices known from the prior art to control the movement of the locking head during operation of the handgun. The control pin is a vulnerable component, precisely because it is typically penetrated by a firing pin hole and is therefore weakened and forms a line of contact with the bolt carrier. Since the control bolt is a relatively small component, it can easily be lost when dismantling the bolt in the field. Furthermore, control bolts according to the prior art are often in operative connection during a bolt return and/or bolt advance with an oblique region of a control cam formed in the bolt carrier in a manner perpendicular to the firing direction. This typically has the consequence that radial forces can always be transmitted to the bolt head due to the oblique control area of the control cam via the control bolt during the bolt return and/or bolt advance, and as a result the bolt head and bolt carrier can become clamped relative to the housing. At least the components involved are subject to significantly greater wear and tear. Therefore, the advantage of the locking device according to the invention is particularly reliable operation of the handgun.

During operation of the handgun, the function of the control bolt can be taken over by the second control device with the at least one control cam. This can be achieved in particular by the interaction of a rear control surface of the control cam of the second control device with the lock carrier. The movement of the locking carrier is preferably stopped by allowing the control cam to be supported on a surface of the locking carrier. The lock carrier preferably rests directly behind it on the at least one control cam of the second control device.

The closure head is preferably arranged to be rotatable and/or linearly displaceable relative to the closure carrier. Particularly preferably, the closure head and the closure carrier are arranged to be axially and/or radially displaceable relative to one another. The closure head and the closure carrier are preferably arranged essentially axially one behind the other and/or rotationally symmetrically along a central axis. In particular, no intermediate elements are arranged between the closure head and the closure carrier. The closure head and the control lugs arranged on it are preferably made in one piece. As a result, a movement of the control cam can directly influence, in particular induce, the movement of the closure head. The locking head can be moved by the movement of the control cam. The closure head can be guided, in particular forcibly guided, in particular in its movement and direction of movement by the control cam. Preferably no relative movement is possible between the at least one control cam of the first control device and/or the second control device and the closure head. The closure head can be positively guided by means of the control cam of the first control device and/or the control cam of the second control device.

In one embodiment of the closure device, the at least one control cam of the first control device is in operative connection with a locking piece in the closure head, the locking piece being arranged in front of the closure head. Preferably, the at least one control cam of the first control device is in operative connection with at least one control flank formed on the locking piece. In particular, the at least one control cam is supported and guided on at least one control flank of the locking piece.

The locking piece is preferably arranged between a barrel of the handgun and the bolt head. It is advantageous here that a linear movement of the closure head, which can be initiated by a recoil, can be forced into a rotational movement of the closure head by the geometry of the control cam of the first control device and the control flank of the locking piece. This advantageously creates a superimposed linear movement and rotary movement of the closure head. The superimposed linear and rotary movement is here preferably induced by a linear, in particular axial, impulse that can be exerted on the closure head.

In particular, the linear impulse can be caused by an expanding propellant charge.

In one embodiment of the locking device, the at least one control lug of the first control device is positively guided in a tube end, in particular by means of the locking piece and/or in connection with a housing structure of the handgun, in such a way that the movement of the locking head at any time t depends on its position in Longitudinal direction is predetermined radially.

In one embodiment of the closure device, the control cam has a first control surface which is arranged on a side facing the closure carrier and which has an inclined surface with an inclination, wherein the first control surface can slide along a front control flank of the locking piece. The control cam of the first control device is preferably guided by it. This allows a rotational movement of the closure head to be initiated. The inclination is preferably in the firing direction. The control surface preferably runs essentially perpendicular to a horizontal central axis surface. The inclination is preferably formed to a normal surface of the central axis surface.

Preferably, the control cam of the first control device has a second control surface, the second control surface being arranged opposite the first control surface of the control cam, the second control surface of the control cam being operatively connected to the locking piece in such a way that a position of the locking head is maintained at any time of locking - and unlocking process is predefined.

The control cam of the first control device preferably has two control surfaces which are in operative connection with the locking piece. The control surfaces are preferably formed on the sides of the control cam facing away from the central axis.

The control cam of the first control device has the first inclined surface in its rear region, the first inclined surface being able to slide along the control flank of the locking piece.

In one embodiment of the closure device, the control cam of the second control device has a control surface which is designed as an inclined surface with an inclination opposite to the inclined surface of the control cam of the first control device. Opposite is understood to mean that the inclination of the control surface of the second control device is aligned counter to the firing direction, with the control surface of the control lug of the first control device being aligned along the firing direction. Here, the inclined surface can slide along a control flank of the closure carrier.

The at least one control cam of the second control device can, in addition to the inclined surface, form a stop surface which, in the unlocked state, abuts against a front surface of the lock carrier. This allows a linear movement of the bolt carrier to be stopped relative to and closer to the bolt head. The transmission of a radial movement component of the bolt carrier to the bolt head can be effectively prevented.

Preferably, the control cam of the second control device has a second inclined surface in its rear region, wherein the second inclined surface can slide along the control flank of the closure carrier.

Preferably, a tangent applied to the control surface of the control cam of the first control device, which is designed as an inclined surface, and is projected onto the central axis when viewed in the firing direction, has a first angle of inclination α, and a tangent which is applied to the control surface of the control cam, which is designed as a second inclined surface, and is projected onto the central axis when viewed against the firing direction Tangent has an inclination angle β.

The angles of inclination α and β to the axis are preferably between 30° and 60°, in particular approximately 45°. Here the angles α and β can follow the relationship α = -β. This enables the superimposed rotary and linear movement of the closure head.

In one embodiment of the closure device, the amount of the inclination angle α between the first inclined surface and the inclination angle β of the second inclined surface is in total approximately between 60° and 120°, in particular the sum of the amounts of α and β equals 90°. Here, the angles α and β can take on different values, in particular be different.

Preferably, the first inclined surface and the second inclined surface are arranged in opposite directions relative to a normal to the central axis. The inclined surface of the control cam of the first control device points in the firing direction and the inclined surface of the control cam of the second control device points against the firing direction. Here, the normal to the central axis of the normal surface can be understood as meaning that the normal surface is aligned perpendicular to a substantially horizontal central axis surface running through the central axis. The surfaces of the first control cam and/or the second control cam are preferably designed as a single-start or multi-start trapezoidal, sawtooth or flat thread or partially as a trapezoidal, sawtooth or flat thread segment or sequentially as trapezoidal, sawtooth or flat thread segments.

The geometric design of the first inclined surface and the second inclined surface preferably determine the translation. In particular, the impulse of the cartridge and the geometric configuration of the first inclined surface and the second inclined surface determine a desired mass of the bolt carrier.

In one embodiment, the closure head is formed in one piece with the first control device and the second control device. Particularly preferably, the closure head and the closure carrier are connected to one another in a force-fitting and/or form-fitting manner.

A control cam of the closure head can be in operative connection with one or alternately different control or guide surfaces with other control surfaces or control flanks or guide surfaces, for example in a groove in the housing and/or in the locking piece. The active connection can be a forced operation. This allows the locking head to be forced into a defined movement. For example, a linear movement of the closure head can be changed into a rotary movement by guiding the control surfaces of the control cam of the closure head along the control flanks on the counter element, for example the locking piece.

During operation of the handgun in which the locking device is inserted, an impulse that is triggered by the conversion of a propellant charge in a cartridge and separates a bullet from a cartridge case and accelerates it forward can be used to relocate the locking device or parts of the locking device. Here, in accordance with the conservation of momentum, the momentum of the projectile is partially absorbed by the housing and the displacement of the mass of the locking device in an opposite direction. As a result, the locking device or parts of the locking device, for example the locking head and/or the locking carrier, can experience a correspondingly small acceleration in relation to the projectile and can move backwards against the direction of fire at a resulting speed. The movement of the closure head is initially radial with a simultaneously superimposed linear movement. The movement of the locking head is initiated by the interaction of the locking piece with the locking head. The bolt carrier, which is in operative connection with the bolt head, moves linearly backwards exclusively, guided by at least one linear groove or longitudinal groove or edge on the housing side. A spring element arranged behind the lock carrier can be compressed. The spring element thus stores the kinetic energy. Generally speaking, after the firing process has ended, the spring element can move the bolt carrier and thus the entire locking device forward again in the firing direction to its basic position ready to fire.

During operation of the handgun, a breech advance is provided, which can support the at least one control cam of the first control device arranged on the breech head with its oblique control surface without play on at least one control flank of a locking piece arranged in front of the breech head. The control flank on the locking piece is in particular an oblique control flank and can function as a control surface. This allows the rotational movement of the closure head to be initiated, in particular the rotational movement of the closure head about a longitudinal axis of the closure head, in particular as long as the closure head simultaneously moves in the longitudinal direction in this area.

Because the control surface of the first control device and the control surface of the second control device are aligned in opposite directions, in particular relative to the longitudinal axis of the breech head, the breech carrier can travel a further distance per unit of time relative to the housing of the handgun than the breech head. Here, the ratio of the bolt carrier path and the bolt head path relative to the housing is directly proportional to the effective angles α, β of the opposing slopes, in particular inclined surfaces of the control lugs. The choice of angles α, β determines the gear ratio and is preferably tailored to the impulse of the cartridge and the mass of the bolt carrier.

In one embodiment, the first control device of the closure device has a second control cam in addition to the at least one control cam. Here, the first control cam and the second control cam are preferably arranged rotationally symmetrically offset from one another by 180°. The first and second control cams of the first control device are preferably arranged radially opposite one another. In the unlocked locking position within the handgun, the first and second control lugs are preferably positioned essentially vertically, i.e. in the 12 o'clock and 6 o'clock positions to one another. An extractor can be arranged on one side of the breech head, offset by 90° to the two control lugs, and can therefore be arranged in the unlocked breech position within the weapon on the horizontal in the 9 o'clock or 3 o'clock position. This has the great advantage that the shooter can easily change the ejection direction from the right side of the casing to the left side of the casing or from the left side of the casing to the right side of the casing by simply turning the breech head by 180° around its longitudinal axis can be adjusted without tools. The bolt head is fixed in the bolt carrier in the preset position with respect to the selected ejection direction via a spring-loaded locking bolt. This is also the optimal mounting position in order to be able to guide the bolt into the weapon housing from behind. Furthermore, the control cam of the first control device in the 6 o'clock position in the unlocked locking position offers the great advantage that a cartridge can be pushed out of the magazine during the locking advance and placed in the cartridge chamber.

In the interaction of one to a maximum of three possible control surfaces of the first control device with their corresponding components on the locking piece, in particular the control flanks, better, in particular more precise, guidance can be achieved.

Alternatively, however, four control lugs can also be provided, each of which is arranged offset by 90° to one another. In the unlocked locking position, control lugs can preferably be arranged within the weapon in the "3 o'clock", "6 o'clock", "9 o'clock" and "12 o'clock" positions. An even multiple of further pairs of control cams can also be arranged, which are also arranged rotationally symmetrically offset by 180° to the closure head axis and can be mirrored on a vertical center plane and a horizontal center plane.

In a further embodiment of the closure device, the second control device has a second control cam in addition to the at least one control cam. The second control device is preferably arranged in the second row. The second control device is preferably arranged directly behind the first control device. Here, the first control cam and the second control cam are preferably arranged radially offset from one another by 180°.

In the interaction of one to a maximum of three possible control surfaces of the second control device with their corresponding components, in particular the control flanks on the lock carrier, better, in particular more precise, guidance can be achieved.

Alternatively, four control lugs can also be provided, each of which is arranged radially offset from one another by 90°. This allows the movement of the bolt head and the bolt carrier to be controlled more precisely. It can be prevented that the components tilt with each other and/or in the housing of the handgun. The symmetrical arrangement supports a uniform and tilt-free movement of the bolt carrier and the bolt head.

The closure head and the closure carrier of the closure device are preferably arranged essentially axially along a central axis, particularly preferably on the barrel central axis. Particularly preferably, the closure head and the closure carrier are arranged axially and rotationally symmetrically to the central axis. Due to the linear, axial and/or rotationally symmetrical arrangement, during operation of the handgun, the impulse emitted by the cartridge can be transmitted, in particular directly, to the bolt head, the locking piece and the bolt carrier. Due to the rotationally symmetrical arrangement, the handgun can easily be redesigned from a left-handed design to a right-handed design and vice versa.

A larger translation can be achieved due to the opposing slopes of the control lugs of the first control device and the second control device. The translation of the first control device and the second control device can be realized by the design. As a result, the closure device, in particular the closure carrier, can advantageously have a small mass. In particular, with a comparable cartridge caliber, a significantly smaller mass can be used than in mass closure systems according to the prior art. This makes it possible in particular to use larger and stronger calibers with the translated mass closure with the closure device according to the invention while at the same time having the same or smaller mass of the closure carrier in the closure device. Due to the axial arrangement of the two control devices, all forces run on a common line of action. The losses are preferably minimized.

A spring element is preferably arranged in the locking device along the central axis behind the locking carrier, the spring element being in operative connection with the locking carrier when installed in the handgun, in particular in direct operative connection with the locking carrier.

In one embodiment of the closure device, the closure head has a rear boundary surface and the closure carrier has a front end surface, which is preferably arranged at 90° to the firing direction. The at least one control cam in the second row preferably supports the lock carrier on the front end face. This ensures that, while the locking device remains in its linear range of motion, no force components can act from the locking head on the locking carrier and vice versa, which could, for example, lead to an inhibition of the locking movement in the housing structure.

Preferably, the breech head has at least partially a rib-shaped thickening in the rear area, wherein the rib-shaped thickening of the breech head can be supported on the breech carrier in such a way that the breech head remains in operative connection with the breech carrier within the handgun. In particular, the bolt head always remains in operative connection with the bolt carrier, particularly at any time during operation of the handgun. The bolt head cannot slip out of the bolt carrier. In particular, the second region or second section of the closure head cannot slide out of the closure carrier.

In one embodiment of the locking device, a shock base is formed on the closure head, with a cartridge resting on the shock bottom without play when installed and ready to fire in the handgun. The butt base is preferably formed on the front area of the locking head facing the locking piece. The butt base of the breech head can rest against the cartridge and the cartridge can be clamped without play between a cartridge chamber and the breech device.

In a preferred embodiment of the closure device, the first control device and the second control device are arranged symmetrically to an axis of rotation of the closure head of the closure device. This means that the entire closure system can be designed to be rotationally symmetrical. The advantage here is that the shutter distance can automatically adjust itself to a shutter distance of zero. The closure distance is to be understood as the distance between a butt base of the closure head, i.e. the front contact surface of the closure head on the cartridge base, and a cartridge base of a case, which rests on its front stop in the cartridge chamber. A cartridge case can always be automatically held or clamped firmly between its front stop surface in the cartridge chamber and the front closure head surface by the locking device according to the invention. This initially preferably prevents uncontrolled, sudden force peaks from occurring if, when the cartridge is ignited, the cartridge case would hit the bottom surface of the breech head. This means that the components of the closure device are protected from material and the durability is significantly improved.

In addition, shooting tests show this feature of the closure according to the invention device significantly improves the precision of the handgun equipped with it.

An extractor, in particular a spring-loaded extractor, can preferably be provided in the closure device. The extractor has the function of pulling the cartridge case out of the cartridge chamber. The extractor is subjected to little stress in the locking device, as the cartridge case is pushed out of the cartridge chamber by the applied gas pressure. In particular, the extractor is subjected to less stress than with locking devices according to the prior art. The extractor can be attached either to the bolt head or to the bolt carrier. The extractor is preferably attached to the bolt head. The extractor is preferably only used when ejecting a cartridge case or when ejecting an unfired cartridge to unload the weapon.

In one embodiment of the closure device, the closure head is formed in one piece with the first control device and the second control device. Preferably, the closure head can be manufactured and/or printed as a milled part and/or turned part, in particular produced using 3D printing. The closure head can thereby be guided, in particular positively guided, by means of the first control device and the second control device. Here, the control surfaces of the first control device can be in operative connection with control flanks of the locking piece and the control surfaces of the second control device can cooperate with control flanks of the lock carrier.

The closure head and the closure carrier are preferably connected to one another in a force-fitting and/or form-fitting manner.

It is advantageous that the closure device is easy to manufacture and robust. Furthermore, the closure device can be insensitive to contamination. The locking device can consist of only a few components and still enable the weapon to be highly precise.

If the cartridge case has a diameter-to-length ratio of, for example, 1:3 or even less favorable and a very small taper, it tends to lidate as long as the propellant gas pressure is applied. The cartridge case can be pressed against the internal geometry of the cartridge chamber by the internal gas pressure and therefore cannot carry out any longitudinal movement. Longitudinal grooves, referred to as relief grooves, are preferably arranged in the cartridge chamber, so that the cartridge case can be surrounded by propellant gas pressure on all sides and the sleeve can reliably drive the closure device according to the invention.

The respective inclination of the control surfaces on the closure head and the choice of the control surface angles α and β make it possible for only partial components of the impulse to be transmitted to the housing. This not only puts less strain on the handgun itself, but also on the shooter.

The relatively large gradient of the inclined surfaces of greater than approximately 30° is advantageous because it can greatly reduce the dependency on friction. Furthermore, foreign particles that have gotten into the closure device can easily be displaced or pushed away.

The locking device according to the invention in the handgun is characterized in particular by a very simple, cost-effective production of the components of the locking head, locking carrier and control devices. Components of the locking device according to the invention do not have to be manufactured and adjusted with very high precision, as is the case with known roller locks, for example in the G3 rifle or the MP5 submachine gun. If wear occurs during long-term use of the closure device according to the invention, the novel closure device compensates for this independently.

The recoil spring can push the bolt carrier of the bolt forward in the firing direction in a normal closing movement. If the breech head with the control lugs of the first control device, in particular in the first row, is located in the oblique control groove area of the locking piece, the butt base of the breech head comes into contact with the base of the cartridge case, which rests in its front area against its stop in the cartridge chamber. This prevents the bolt head from moving further forward.

However, since at the same time the bolt carrier can rest with its oblique control flanks on the control surfaces of the control lugs of the bolt head in the second row, the bolt head blocked in the longitudinal direction is preferably rotated further radially until the control surfaces of the bolt head in the first row rest on the analog control flanks in the locking piece come to the facility.

This can also prevent the locking head from turning any further. The locking carrier preferably holds the locking head in this position in a linear and radial manner by the pressure force of the closing spring applied to the back of it and thereby adjusts it Make sure that the cartridge or cartridge case is always clamped in the chamber without any play.

Structurally, the locking device is set up in such a way that the locking carrier always comes into contact with the control surfaces on the control lugs of the locking head in the second row in such a way that it always exerts a radial force component on the locking head located in the locking area of the locking piece.

There can therefore always be a gap or distance from the bolt head lug in the second row in the recess of the bolt carrier opposite its control surface.

Because the bolt carrier does not hit the front of a steel part that is firmly anchored in the housing in the bolt advance, but instead hits inclined surfaces on the bolt head and/or a cartridge case made of a rather soft case material, the risk of bounces acting on the bolt carrier can be greatly reduced. This is particularly advantageous because a bolt that impacts during the closing process can cause a serious disruption to the weapon's function, especially in rapid firing sequences.

The insensitivity of the closure device according to the invention to rough tolerances as well as the independent compensation of wear is preferably made possible and reinforced by the, in particular, very wide design of the control cams in the first row and second row, since the wide design of the control cams results in a relatively large effective radial control path along of the flank diameter of the control surfaces in radians.

The particularly very wide design of the control cams in the first row and second row also brings with it a very big advantage for safety reasons, since the control cams in the first row remain on the for a relatively long time when firing a cartridge with an incorrect, too strong charge Support the corresponding control edge in the locking piece.

The control lugs, in particular the control lugs in the first row, are preferably designed to be so wide that they still fit horizontally between the magazine lips with the distance required for tolerance reasons. Here, control lugs are to be understood as meaning the at least one control lug of the first control device and/or the control lugs of the second control device. As is usual in the prior art, the magazine lips are arranged on the side of a magazine facing the closure device. The magazine lips are preferably arranged on a long side that approximately corresponds to the length of the cartridge. The distance between the two magazine lips, viewed horizontally from the side, is preferably arranged symmetrically to the magazine housing, so that the control cam of the first control device can pass through when it is in the 6 o'clock position.

One advantage is that, apart from a pure ground closure, the number of components and/or assemblies is also smaller than in closure systems according to the prior art. It is also advantageous that the individual components do not require as strict tolerances as the components in closure systems according to the prior art.

Another advantage of using the locking device according to the invention is the smaller space requirement, the compact external dimensions and this results in a narrower silhouette of the firearm. This allows a lower line of sight to be achieved. The handgun as a whole becomes much more manageable and can also be grasped more easily with one hand.

The locking device according to the invention can be used in both automatic handguns and semi-automatic handguns.

During the firing of a cartridge, a force can be exerted on the bolt head by the cartridge case, which can push the bolt head backwards in an opening movement and the bolt carrier, due to the first control device and the second control device, moves further and further away from the bolt head moving backwards can be pushed away as long as the impulse initiated by the cartridge is effective and at least one front control cam is located in the sloping control surface area of the locking piece.

The object is also achieved by a handgun, the handgun having a housing and a barrel, a locking device according to the invention being arranged in the housing.

The barrel may be a substantially cylindrical tube. The pipe internal geometry can be provided with a spiral-shaped tension and field profile or a polygonal profile. This is advantageous for causing the fired projectile to rotate within the barrel in order to stabilize it for its subsequent flight phase. However, it can also be a smooth tube. The tube can accommodate a cartridge that is at least contains at least one bullet and one cartridge case. The tube is preferably made of a material that offers the lowest possible resistance to the magnetic field lines of a current-carrying coil.

The locking device built into the handgun has the locking head and the locking carrier. The closure head and the closure carrier are preferably arranged axially one behind the other and are in operative connection. In particular, they are arranged in a non-positive and/or positive manner, at least in some areas.

A locking piece is preferably arranged in front of the locking head at the end of the pipe, the locking head being in operative connection with the locking piece.

In an advantageous embodiment of the handgun it is provided that a spring element is arranged behind the bolt carrier of the locking device along the central axis and viewed against the direction of fire, the spring element being in operative connection with the locking device, in particular directly in operative connection with the bolt carrier.

The spring element can be compressed by an axial movement of the bolt head and the bolt carrier, which are axially displaced by the recoil of the cartridge case when the projectile is fired. The spring force allows the bolt head and the bolt carrier to be moved axially forward.

The axial displacement of the locking device to the rear can preferably be achieved via the impulse introduction of the cartridge case onto the butt base of the locking head, by the first control device, which is supported on the control flanks in the locking piece, and the second control device, which is supported on the control flanks on the locking carrier .

The handgun is preferably constructed in the AR15 or M4 design, in particular the necessary controls are arranged as usual in the AR15 or M4 design.

The handgun is preferably set up for ammunition in the caliber range from approximately 4 mm to approximately 50 mm. The closure device is designed in particular for cartridge cases with a relatively large diameter-length quotient. In particular, cartridge cases without extreme taper at a case mouth can also be used in the firearm with the locking device according to the invention.

The handgun is preferably also set up to program and fire intelligent ammunition arranged in the cartridge chamber of the barrel. The handgun is particularly preferably set up to fire intelligent ammunition. Projectiles of this ammunition have electronic components which, in one embodiment, can communicate with the handgun and/or the handgun can communicate with the ammunition.

In one embodiment, smart ammunition can be programmed to explode in mid-air at a specific point along the trajectory using a laser range finder and ballistics computer. For example, this can hit an enemy behind an earth wall. The range can be over 500 meters.

The housing of the handgun is preferably designed as a one-piece lightweight construction and a magazine shaft, a connecting structure, a receiving structure for a fire control computer, a receiving structure for a trigger mechanism, and preferably an ejection opening for cases and cartridges are provided on both sides. Furthermore, a receiving structure for a pipe end and/or locking piece are formed, in particular integrally with the housing. Furthermore, a receiving structure for a handle cover is preferably provided. The one-piece lightweight construction can be constructed from a thermoplastic and/or thermoset matrix and reinforcing fibers.

In a preferred embodiment of the handgun, the housing comprises a plastic structure with a thermoset and/or thermoplastic matrix. In particular, the housing comprises a thermoplastic matrix and reinforcing fibers. In particular, at least the locking piece or a holding component for the locking piece is integrated into the housing, in particular the plastic structure.

The reinforcing fibers are preferably provided in the form of fiber snippets or fiber chips. According to relevant literature, fiber chips or fiber snippets are relatively thin, rectangular or strip-shaped pieces in which several centimeters long, longitudinally oriented, unidirectionally arranged fibers are embedded in a matrix material. The fiber chips or fiber snippets are usually placed in the tool in a disordered manner for component production.

The use of the thermoplastic matrix, in particular with the fiber chips, has the advantage that the fiber chips are recyclable and/or are a recycled raw material. The reinforcing fibers are preferably carbon fibers and/or glass fibers and/or aramid fibers or a combination of different fibers, such as carbon fibers and/or glass fibers and/or aramid fibers. The combination of matrix and reinforcing fibers allows the housing to be very rigid. Furthermore, the combination of matrix and reinforcing fibers enables the housing to be very strong. In addition, good damping properties can be achieved.

During the manufacturing process, the matrix and the reinforcing fibers are pressed into the housing under pressure and elevated temperature in a largely automatic process. A 3D component is created, which is preferably made in one piece. Components that are made of metal, such as the locking piece or a holding component for the locking piece, can be inserted into the matrix during the pressing process and integrated at the same time. This means that interfaces can be manufactured in one piece with the fiber composite housing and/or the plastic structure.

In a particularly preferred embodiment of the handgun, the housing structure has replaceable, electrically conductive areas or partial areas that are protected from external influences and which connect various electrical or electronic functional areas within the handgun, preferably without further interfaces, and are particularly preferably designed in one piece . These electrically conductive areas or partial areas can also be permanently incorporated into the housing structure, preferably during production.

All electrical and electronic functional elements, such as sensors, buttons, switches, shot counters, programming coils, interfaces to external functional modules, such as a fire control computer, etc. can preferably be connected to a cable harness or cable harness and protected against external influences and as an overall assembly in the Housing structure can be attached.

In a further embodiment of the handgun, the electrically conductive areas or partial areas of the housing structure have at least one electrical or electronic interface, in particular also in conjunction with a mechanical interface, in order to transfer information and/or energy between the handgun and external ones attached to the handgun To be able to exchange or move modules, such as a fire control device or external modules that are not attached to the handgun, such as a service computer.

In particular, it is preferred that switching elements or sensors are attached to the electrically conductive areas or partial areas in the housing structure, which can detect relevant positions of weapon components and/or environmental data as well as control commands from the user.

In a method for producing a handgun with a housing and a locking device, the housing can be made from a thermoplastic or thermoset matrix with reinforcing fibers by pressing fiber chips under pressure and elevated temperature, with connecting parts, in particular metal connecting parts, for example the locking piece in the Pressing process can be integrated directly. Fiber composite mats can also be partially or completely inserted into the tool in order to further increase the strength and rigidity of the housing structure.

This allows the housing to be manufactured in an automated process. Connecting parts, such as the locking piece, can also preferably be integrated in the same process step. This creates an automated manufacturing process for the casing of the handgun, the handgun casing. This has the advantage of a cost-effective manufacturing process for the handgun, especially the housing.

The magazine housing can be manufactured using the same process and materials as the weapon housing, and metal parts can also be integrated.

It is advantageous to produce a handgun that is as light as possible and allows very compact external dimensions in relation to the cartridge diameter.

The preferred mode of operation of the locking device in the handgun is summarized in its essential elements below. In a basic position, the control surface of the first control device of the closure head, which is designed in the firing direction, rests on the control flank of the locking piece. Due to the compressive force of the closing spring, the locking carrier rests with its control flank on the control surface of the locking head, which is aligned opposite to the firing direction, in particular without play. When the propellant charge is ignited and the gases of the propellant charge expand, a substantially axial force impulse directed counter to the firing direction is exerted on the bolt head. The ver The firing head is pressed against the direction of the shot. Due to the positive guidance of the control surfaces of the first control device of the locking head on the control flanks of the locking piece, the locking head is forced into a rotary movement. At the same time, the bolt carrier is pushed away from the bolt head as the control surfaces of the second control device slide along the control flanks of the bolt carrier. This movement of the locking carrier occurs until the control cam of the second control device is supported on the front end of the locking carrier. This initially stops the movement of the bolt carrier relative to the bolt head against the firing direction. The locking head rotates a little further because the operative connection of the control surfaces of the first control device with the control flanks of the locking piece lasts a little longer. At this point the bullet has left the barrel. Essentially due to the stored kinetic energy in the closing spring, the locking device is pushed back into the starting position.

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

In the description, the figure description and the claims, the terms "front", "rear", top and bottom are used in the known form and in relation to a handgun used in the usual manner. This means that the muzzle of the barrel is "at the front", that the locking device is moved backwards, in particular by the explosion gases, etc. The axial direction is to be understood as the direction of the barrel axis (axis of the barrel), which typically runs along the central axis .

All features and advantages listed in connection with the locking device also apply to the handgun without being explicitly listed in the description of the handgun.

Character description

The subject matter of the invention is described in more detail below with reference to the objects shown in the figures. The same objects are given the same reference numbers in the figures.

1 shows a handgun 10 in an isometric, schematic representation, viewed obliquely from above. The terms “front” and “back” as well as “in front” and “behind” in the firing direction indicated by arrow 12 - referred to as firing direction 12 - are described below. A fired shot exits the front of the handgun 10.

The handgun 10 has a housing 14 which has a shoulder rest 16 at its rear end. A trigger 20 is arranged on the housing 14 with a handle cover 18 to which a trigger guard 22 is attached. A fire selector lever 21 also protrudes from the housing 14 - preferably on the right and left side of the weapon housing. The trigger 20, a cock 23 (not shown) (shown in 2 B) and the fire selector lever 21 with a fire selector lever axis 21' together form a trigger mechanism.

A magazine shaft 24 for receiving a magazine 26 with a magazine base 28 is also arranged on the housing 14. An operating window 30 is arranged on the magazine shaft 24. The magazine 26 has a substantially rectangular shape and has magazine lips (not shown) formed at one end which extend oppositely along a cartridge length of the cartridge 62 located in the magazine. The housing 14 has an ejection window 32 on the left side (shown) and also on the right side (not shown), which is suitable for ejecting a cartridge case after a shot has been fired. Even when the handgun 10 is unloaded, a cartridge 62 that has not yet been fired is generally ejected from the ejection window 32. The ejection window 32 can be arranged on both the left and the right side of the housing 14. The housing 14 is preferably manufactured with an ejection window opening 32 on each side, with the unused ejection window 32 being closed with a piece of material. The same housing 14 can therefore be used for both right-handed and left-handed handguns 10.

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

Seen geodetically, a fire control unit 40 is arranged above the housing 14, which can be designed as a fire control computer 40. A through-loading unit 42 or a through-loading mechanism 42 is arranged between the housing 14 and the fire control unit 40. 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.

In the housing 14, when the handgun 10 is fully assembled, in the area of the ejection window 32 there is an in 1 Locking device 44, not shown, is arranged and is described in more detail in the following figures.

2a shows the handgun 10 in a schematic representation in a longitudinal section along the firing direction 12. A center line 5 runs in the longitudinal direction essentially parallel to the firing direction 12. The center line 5 runs centrally in the weapon barrel 34 and the locking device 44. The tap 23 is assigned to the trigger 20, which is in operative connection with the trigger 20. The axis 21 'of the fire selector lever 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 closure device 44 can be seen.

The locking device 44 is also referred to as a locking device 44 and has a locking head 46, a locking carrier 48, a firing pin 50 and a spring-loaded locking pin 52. A locking lug, which locks the firing pin 50 in its functional area, is in 2a Not shown. The closure head 46 is arranged in front of the closure carrier 48. The firing pin 50 is arranged centrally in the closure head 46 and the closure carrier 48, in particular arranged in a movable manner. The spring-loaded locking bolt runs in the locking carrier 48 and essentially transversely to the central axis 5. A locking piece 68 is arranged in front of the locking head 46. The locking piece 68 radially encloses a tube end 19 of the weapon barrel 34, which is arranged in sections in the area of the housing end 15. The locking piece 68 is radial arranged between the housing 14 and the pipe end 19, in particular arranged radially in sections between the housing 14 and the pipe end 19. A cartridge riser 70 runs in the locking piece 68.

The closure head 46 is arranged to be movable relative to the tube end 19 of the barrel 34 and/or locking piece 68. The closure head 46 is arranged to be movable in particular in the radial and axial directions. When firing a projectile, a cartridge 62, the breech head 46 can be displaced axially backwards at least partially radially and at the same time superimposed in the horizontal direction, as long as the breech head 46 is in operative connection with an oblique groove region of the locking piece 68. Here, the movement of the closure device 44 takes place essentially along the arrow 12 and against the direction of the arrow. More information about this is described in the following figures. The locking piece 68 has control flanks which come into operative connection with control lugs (not shown) of the breech head 46, namely when closing the breech device 44 in the breech advance in the firing direction 12 and when opening the breech device 44 in the breech return against the firing direction 12, when a shot is fired. In the area of the bolt carrier 48, a recess or recess or recess 54 is provided, which serves to ensure that the cock 23 can reach the firing pin 50 in the basic position of the weapon, ready to fire.

A first recoil spring guide tube 56 and a second recoil spring guide tube 58 and a recoil spring 60 are arranged downstream of the closure carrier 48 (opposite to the firing direction indicated by arrow 12). Also shown are the cartridge 62, which is arranged half in the cartridge chamber 64 of the weapon barrel 34, and a bobbin 66 with a winding. The coil is used to program intelligent ammunition. Furthermore, the cartridge riser 70 can be seen. Through the cartridge riser 70, a cartridge 62 can get from the magazine 26 into the cartridge chamber 64.

2 B shows a section of the handgun 10 in a sectional view. The same objects are designated with the same reference numbers as in the previous figures. The closure device 44 can be seen more clearly. A driving surface Q can be seen on the lock carrier 48. A power supply unit, for example a battery, in particular a rechargeable battery, can be provided in the handle cover 18.

3 shows the housing 14 in an isometric view obliquely from above. The same objects are designated with the same reference numbers as in the previous figures. In the front area 15 an interior 72 of the housing 14 can be seen. The locking piece 68 is accommodated in the interior 72 of the housing 14 when the handgun 10 is assembled. Here, the locking piece 68 is preferably glued directly without play, laminated, injected, screwed in, welded, soldered or pinned or fastened in this area via a holding component which is glued, laminated, injected, screwed in, welded, soldered or pinned into the housing 14 . Preferably, the locking piece 68 or the holding component for the locking piece 68 is inserted in the manufacturing process of the housing 14.

During operation of the handgun 10, the cartridge 62 can be moved from the magazine 26 into the cartridge chamber 64 of the barrel 34 (not shown) through an opening 74. Here, the magazine 26 has a magazine housing 26, which is arranged in the magazine shaft 24. Furthermore, the magazine 26 has magazine lips, not shown, as are also common in known magazines. A longitudinal groove 76 ', which is arranged on the inner lower part of the housing 14, can be seen. The locking device 44 installed in the handgun 10 can move in the longitudinal groove 76', for example when a shot is fired with the handgun 10 or the handgun 10 is loaded. The width of the longitudinal groove 76, 76' corresponds approximately to the clear width between the magazine lips. The longitudinal groove 76 merges into an oblique transverse groove (not shown) in the area of the locking piece 68 facing away from the barrel 34. The longitudinal groove 76' is formed both in the lower region and in the upper region of the housing 14.

The longitudinal groove in the upper area is in 3 not shown and is designated by reference number 76. The lock carrier 48 can be positively guided by means of the longitudinal groove 76 and/or 76'. By means of the longitudinal groove 76 and / or 76 ', but preferably the longitudinal groove 76, which partially continues forward in the firing direction 12 in the locking piece 68 and merges into an oblique transverse groove 92 in the area of the locking piece 68, the locking head 46 of the locking device 44 can be in be forcibly guided in every position. The longitudinal groove 76 'is interrupted here by the cartridge feed opening 74. The locking piece 68 is in the 3 however not shown. The radial and linear alignment of the entire closure device 44 at each time t is predetermined depending on its position in the longitudinal direction along the center line 5.

Furthermore, on the housing 14 there is a receiving structure 77 for the trigger mechanism, which includes at least the trigger 20, the spring-loaded cock 23, the fire selector lever 21 with the fire selector lever axis 21 'and the handle cover 18, preferably with the trigger guard 22, which are in the 1 and 2 are shown. The receiving structure 77 can be shaped or designed in such a way that it can reinforce or stiffen the slotted area of the housing structure 14 in a weight-neutral manner, which is necessary so that the cock 23 of the trigger mechanism can reach the firing pin 50.

In the upper area of the housing 14, which is closed to the outside, a guide 71 for the through-loading unit 42 and a receptacle 73 for a cable duct are arranged.

The housing 14 is constructed in one piece and therefore has no unnecessary weak points. The housing 14 with its entire housing structure 14 is designed as a robust and stable lightweight construction. The housing structure 14 comprises a tunnel or tubular sub-structure.

In particular, the receiving structure 77 is molded on for the trigger mechanism and is therefore formed in one piece with the housing 14. A necessary longitudinal slot in the upper housing area, which ensures that the loading unit 42 can come into operative connection with the bolt carrier 48 when loading the weapon 10, is reinforced and stiffened by a composite structure 43 or overlap structure 43. The housing 14 has two grooves, an upper longitudinal groove 76 (not shown here) and the lower longitudinal groove 76 ', in which the closure device 44 is positively guided in the longitudinal direction in the opposite direction and in the firing direction 12. A radial movement of the closure device 44 about its longitudinal axis 5 is prevented when the cartridge 62 is fired and the closure device 44 or the closure head 46 is no longer in operative connection with the locking piece 68. The longitudinal grooves 76 and 76' each have a width, not shown, from one side surface 76a to the opposite side surface 76a. The width of the longitudinal grooves 76 and 76' corresponds approximately to the distance or the clear width of the magazine lips of the magazine 26.

The material of the housing 14 is preferably a fiber composite material. At the front end, the locking piece 68 is connected directly and in one piece and therefore without play to the housing structure 14. However, the locking piece 68 can also be connected to the housing structure 14 without play via a holding structure that is connected to the housing structure 14 directly and in one piece and thus without play. The housing structure 14 is reinforced by thickenings in the areas where recesses are arranged. Thickenings and/or reinforcements are understood to mean, for example, double or multiple layers of fiber composite material.

The cartridge feed opening 74 and/or a part of the magazine shaft 24 are also designed in one piece with the housing 14 and/or molded onto it. In the housing 14, reinforcements through metal inserts, which are locally limited, are preferably arranged in areas that partially absorb large forces during firing.

Furthermore, known or future interfaces are provided or anchored on the housing 14, via which known or future existing accessories can be connected to the handgun 10. These are, for example, aiming aids such as rear sights and front sights, lasers and/or a fire control computer 40. The aiming aids can be connected to the housing 14 without play via these interfaces and are then an integral part of the handgun 10. The interfaces also contain electronic interfaces, for example for the fire control computer 40.

A partial structure of the housing structure 14 is preferably made of steel or an alternative material. At a front end of the housing structure 14, the locking piece 68 is arranged and/or formed and/or integrated and preferably connected in one piece to the housing part structure. The housing structure 14 can alternatively also be a tunnel- or tubular partial structure reinforced and/or supplemented by a fiber composite structure and/or a plastic or a metal structure.

The housing 14 or the housing structure 14 can be made of fiber composite material, with the locking piece 68 arranged and integrated at the front end 15 in the interior 72 and preferably directly with the housing structure 14 in one piece without play or also via a holding body with it Housing structure 14 is connected without play.

The housing structure 14 is preferably completely closed on all sides and/or designed in one piece. As a result, the housing structure 14 is not only very stable and robust, but also very thin-walled and can therefore be made extremely light.

In the housing structure 14 there are only functionally absolutely necessary openings in the surfaces and side surfaces arranged perpendicular to the central axis 5, such as the ejection window 32, which can preferably be arranged on the right and left side of the weapon, the cartridge feed opening voltage 74, which is preferably arranged on the lower side of the weapon, and a cock recess, which is preferably also arranged on the lower side of the weapon, are introduced.

The slotted area extending at the top in the longitudinal direction, in which the loading unit 42 engages the lock carrier 48 on its driving surface 85 during the loading process through the housing structure 14, is firmly closed by a composite structure 43 or overlap structure 43 and so supported.

To increase the kink resistance and torsional rigidity in the area of the recesses, in particular in their edge areas, the housing structure 14 preferably has a thickening, which is preferably formed in one piece or is introduced by a reinforcement or a cavity, also formed with a filler .

The housing structure 14 is preferably designed as a one-piece hybrid component, in which each partial area of the housing structure 14 is tailored to the partially acting forces in terms of strength, weight, costs and also feel. Hybrid component is to be understood here as meaning that the housing 14 has a combination of fiber composite materials and/or metal components and/or plastics. The housing structure 14 is optimally matched at every point to all load paths that occur during use in order to make the housing structure 14 very stable and robust and also very light, i.e. without accumulating unnecessary weight. The housing structure 14 is basically similar to the bionic structure, comparable to the trunk and roots of a tree or the structure of a bone.

1. 1) Das Gehäuse 14 umfasst eine Faserverbund-Struktur, wobei die bionische Struktur insbesondere durch einen partiell mehrlagigen Aufbau realisiert wird. Der mehrlagige Aufbau umfasst eine gewebte und/oder gestrickte lastpfad-optimierte Gewebestruktur. Ferner weist das Gehäuse 14 einlaminierte tragende und auch nicht tragende Füll-und Aussteifungskörper auf. Das Rohrende 19 und/oder das Verriegelungsstück 68 mit seinen Steuerflanken, welches bevorzugt aus Metall gefertigt ist, wird bereits während der Fertigung der Gehäuse-Struktur 14 in die Faserverbund-Struktur einlaminiert oder eingeklebt. Alternativ wird ein Haltebauteil aus Metall zur Aufnahme des Rohrendes 19 und/oder des Verriegelungsstücks 68 bereits während der Fertigung der Gehäuse-Struktur 14 in die Faserverbund-Struktur einlaminiert oder eingeklebt.
2. 2.) Die Gehäuse-Struktur 14 ist zumindest partiell aus Metall und weist eine konventionelle rohrförmige Blechstruktur mit angebrachtem Dreh-/Frästeil und Hinterschnitten auf oder ist bevorzugt als gedrucktes Bauteil gefertigt. Hierbei kann zumindest der Steuerflanken-Bereich der Verriegelungsstück-Struktur 68 bzw. die Verriegelungsstück-Struktur 68 gleich in die Metall-Struktur integriert werden. Es handelt sich dabei um ein lastpfad-optimiertes bionisches Bauteil, welches sich bis an das Ende der Gehäuse-Struktur 14 erstrecken kann, besonders bevorzugt jedoch zumindest teilweise in die Faserverbund-Struktur eingebettet wird. Die Faserverbund-Struktur weist einen Thermoplast und/oder einen Duroplast auf und kann gefüllt und ungefüllt sein.
3. 3.) Das Gehäuse 14 und/oder die Gehäusestruktur 14 umfasst eine Kunststoff-Struktur aus einer duroplastischen und/oder thermoplastischen Matrix und Verstärkungsfasern, wobei das Verriegelungsstück 68, das Haltebauteil für das Verriegelungsstück 68 und/oder eine konventionell aufgebaute Metall-Struktur mit Verriegelungsstück 68 oder ein gedrucktes Metallteil, welches jeweils zumindest mit den Steuerflanken oder den Verriegelungsflanken des Verriegelungsstückes 68 ausgestattet ist, in die Matrix mit den Verstärkungsfasern eingebettet werden.

Three examples are listed below:

1. 1) The housing 14 comprises a fiber composite structure, the bionic structure being realized in particular by a partially multi-layer structure. The multi-layer structure includes a woven and/or knitted load path-optimized fabric structure. Furthermore, the housing 14 has laminated load-bearing and non-load-bearing filling and stiffening bodies. The pipe end 19 and/or the locking piece 68 with its control flanks, which is preferably made of metal, is already laminated or glued into the fiber composite structure during the production of the housing structure 14. Alternatively, a holding component made of metal for receiving the pipe end 19 and/or the locking piece 68 is laminated or glued into the fiber composite structure during the production of the housing structure 14.
2. 2.) The housing structure 14 is at least partially made of metal and has a conventional tubular sheet metal structure with an attached turned/milled part and undercuts or is preferably manufactured as a printed component. Here, at least the control flank area of the locking piece structure 68 or the locking piece structure 68 can be integrated into the metal structure. This is a load path-optimized bionic component, which can extend to the end of the housing structure 14, but is particularly preferably at least partially embedded in the fiber composite structure. The fiber composite structure has a thermoplastic and/or a thermoset and can be filled and unfilled.
3. 3.) The housing 14 and/or the housing structure 14 comprises a plastic structure made of a thermoset and/or thermoplastic matrix and reinforcing fibers, wherein the locking piece 68, the holding component for the locking piece 68 and/or a conventionally constructed metal structure with a locking piece 68 or a printed metal part, which is each equipped with at least the control flanks or the locking flanks of the locking piece 68, can be embedded in the matrix with the reinforcing fibers.

The components of the plastic structure are automatically pressed in a tool under pressure and elevated temperature to form the complex housing structure 14, in particular pressed as a 3D molded part. This makes series production possible, high reproducibility can be achieved and the housing 14 can be manufactured economically at low costs. Good damping properties of the housing 14 can be achieved through the combination of matrix and reinforcing fibers. The housing 14 also has very good rigidity and strength properties.

The thermoplastics polyamide (PA), polycarbonate (PC), PEEK, PEI, PPS and PES as well as some thermosets are suitable as materials for the matrix. Carbon fibers and/or glass fibers and/or aramid fibers are used as materials for the reinforcing fibers. The carbon fibers have the advantage of a lower specific density.

The mechanical component properties can be adjusted almost arbitrarily by the fiber length, the fiber type and the percentage of fiber volume.

Areas of the housing structure 14 that are subject to very high loads can be reinforced by additional fiber mats or fabrics introduced during the manufacturing process.

Thermoplastic materials are preferably used for the matrix so that the fiber snippets or fiber chips contained in the component structure can be recycled. The matrix preferably has resins, for example phenolic resins and/or melamine resins and/or urea resins.

Material analysis and/or structural analysis can be used to demonstrate on the finished housing 14 whether the housing structure 14 of the handgun 10 was manufactured using a method from a matrix with fiber snippets or fiber chips.

Insert components that are preferably already inserted during the manufacturing process sit permanently without play in the described plastic structure of the weapon housing 14.

Receiving structures for military and civilian interfaces are embedded in the plastic structure of the weapon housing 14 in a similar way to the metal components described, such as the locking piece 68.

The construction variants described for producing a light and robust housing structure 14 can be combined.

In the case of the housing structure 14, the cartridge feed opening 74 is preferably stiffened and/or reinforced in a weight-neutral manner by molding the magazine shaft or at least part of the magazine shaft in one piece onto the housing structure 14.

The handgun 10 with the housing 14 or the housing structure 14 is of light construction compared to handguns known in the prior art and is set up, for example, for very powerful and large calibers due to the reinforcements. Due to the structural design described, the housing 14 can permanently withstand the resulting large forces.

In order to counteract a partial failure of the housing structure 14 when it is constructed from plastic(s) and/or fiber composite material(s) and/or light metal, metal inserts, for example made of steel, are preferably introduced in areas in which large loads are partially applied and forces attack in order to be able to introduce them flatly into the housing structure 14.

The handgun 10 with the housing 14 or the housing structure 14 has the guide track 71 arranged inside the housing structure 14, in which the loading unit 42 is received and guided.

The handgun 10 with the housing 14 or the housing structure 14 has a guide or support contour in its rear upper outer area, which moves the loading device moving backwards out of the housing structure 14 during the loading process. Unit 42 completely or partially guides and/or supports.

The handgun 10 with the housing 14 or the housing structure 14 has the trigger mechanism 20, 21, 23 attached directly to the housing structure, the interaction of the trigger mechanism with other adequate mechanical and / or electrical / electronic functional components the weapon can be checked easily and in detail after the handle cover 18 has been removed.

The handgun 10 with the housing 14 or the housing structure 14 and the trigger mechanism 20, 21, 23 attached directly to the housing structure 14 is covered by the handle cover 18 and thus protected against external influences. The handle cover 18 is preferably placed over the trigger mechanism mounted on the housing structure 14 and is also attached to the housing structure 14.

The handgun 10 with the housing 14 or the housing structure 14 provides the locking piece 68 firmly anchored in the housing structure 14, which directly or indirectly receives a weapon barrel 34 at its rear end 19 and permanently frees it from play relative to the military or civilian Interfaces on the housing structure 14 or any aiming aids attached directly to the housing structure 14 or integrated into the housing structure 14 are fixed and aligned.

The handgun 10 with the housing 14 or the housing structure 14 accommodates a support plate or a base piece in the rear area, which closes the housing internal structure 14 to the rear. This support plate or the base piece can also be connected to an end cap.

The handgun 10 with the housing 14 or the housing structure 14 accommodates the locking device 44 in an interior - preferably with the closing spring unit 60 attached - and stores and guides the locking device 44 in a defined manner.

The handgun 10 with the locking device 44 and a cartridge feed from a very quickly replaceable cartridge holder magazine 26 and a very light and robust housing structure 14 with a total width which corresponds to approximately twice the cartridge ra and whose width is in the area of The hand guard 38 enveloping the weapon barrel 34 can be reduced to less than 1.3 times the cartridge capacity, is characterized by the fact that the handgun 10 can withstand the stresses in continuous military use.

The housing structure 14 and the locking device 44 for the handgun 10 can preferably have a standard design (magazine 26 arranged in front of the trigger 20 and the handle cover 18), but also in a bullpub design (magazine 26 behind the trigger 20 and the Handle cover 18 arranged).

The handgun 10 with the housing 14 or the housing structure 14 and the locking device 44 can be designed in an M4/M16 style in that the operating elements, such as the charging lever 42, are designed in an M4/M16 style. Operate the shooter in the usual way.

The housing 14 has a receptacle for a cable duct 73 in its upper area. Furthermore, the guide track 71 for the through-loading unit 42 is formed in one piece on the housing 14. A through-loading area 41 is shown in dashed lines. A loading lever 42 ', not shown, is pulled out of the housing 14 and the locking device 44 is actuated or the handgun 10 is loaded. A support and guide contour 47 can be seen in the upper area of the housing 14.

4a (isometric view) and 4b (side view) show a schematic representation of the locking device 44 in the locked state. The same parts/objects are provided with the same reference numbers as in the previous figures. The closure device 44 has the closure carrier 48 and the closure head 46. The closure head 46 has a front region in which at least one control cam 78 of the first control device is arranged in the first row 75 and at least one control cam 79 of the control device is arranged in the second row 75 '. The closure head has an SVK front surface and a HVK rear surface.

The control cam 78 has a rear control surface 80, which is designed as an inclined surface 80 or as an inclined flank 80 with an inclination with the inclination angle α. The inclination of the control surface 80 is in 6h explained in more detail. Furthermore, the control cam 78 has a front control surface 87. The front control surface 87 and the rear control surface 80 can be operatively connected to the locking piece 68 when the locking device 44 is installed in the handgun 10. In this exemplary embodiment, a total of two control cams 78a and 78b are arranged on a front region 75 of the closure head 46. The control cams 78, 78a, 78b are arranged radially offset from one another by 180° on the closure head 46. The control cams 78, 78a, 78b are arranged in the first row 75.

Further control cams 79, 79a, 79b are arranged in the further rear area 75' of the closure head 46 and thus in the second row. The control cams 79 in the second row 75 'are arranged radially offset from one another by 180 ° on the closure head 46. The control cams 79, 79a, 79b have a front control surface 86 (not shown) which has an angle of inclination β. The control cams 79, 79a, 79b are in operative connection with the lock carrier 48.

The control cams 78a and 78b can engage in control flanks (not shown) of the locking piece 68. The control cams 79, 79a and 79b are in operative connection with control flanks of the lock carrier 48.

In the 4a and 4b Two front control cams 78a and 78b and two rear control cams 79a and 79b are shown. However, it is also provided to arrange four or more front control cams 78 and four or more rear control cams 79 on the closure head 46. Accordingly, more control surfaces are then provided on the lock carrier 48. A pair of control flanks on the lock carrier 48 is therefore always assigned to a pair of control cams 79.

Furthermore, a spring-loaded extractor 81 is arranged on the closure head 46. The closure head 46 has a butt base 82 against which the cartridge 62, not shown, can rest when the closure device 44 is installed in the housing 14 of the handgun 10. A recess 83 for an ejector fixed to the housing is arranged on the closure head 46, the ejector being able to engage in the recess 83 when the closure device 44 is installed in the housing 14, as shown in 2 is shown and then moves backwards against the direction of the shot. Instead of the ejector fixed to the housing, a spring-loaded ejector mounted in the closure head 46 can also be used.

On the upper part of the lock carrier 48, a driving surface 85 can be seen, which is used to produce Positioning an active connection with the through-charging unit 42 is set up.

The lock carrier 48 has an end face SVT. The control cam 79 formed on the locking head 46 can be supported on the end face SVT of the locking carrier 48 when the locking device 44 is unlocked.

4c shows the locking device 44 in the installed state in the handgun 10. The illustration is an isometric view seen obliquely from behind. In addition to the objects already described, a side surface 76a of the upper longitudinal groove 76 can be seen.

5a (Lock locked) and 5b (Lock unlocked) show the locking device 44 in a schematic representation as a top view. The control cams 78, 78a and 78b can be seen in the front area 75 and thus in the first row on the locking head 46 and the control cams 79, 79a and 79b in the rear area 75` in the second row on the bolt head 46. In 5b the control cam 79 has slipped out of the area of the control flank of the bolt carrier 48 and the distance A` between the bolt head 46 and the bolt carrier 48 is now significantly larger than the distance A in 5a . Here, the control cam 79 is supported with a rear end X on the locking carrier 48, in particular on an end face SVT of the locking carrier 48. In the unlocked state 5b the bolt carrier 48 has moved backwards away from the bolt head 46 against the firing direction 12. It can be seen that due to a previous combined rotational and linear movement of the locking head 46, the control cam 79 lies in a different position relative to the locking carrier 48 in the unlocked state radially and in the longitudinal direction. The bolt carrier 48 has moved counter to the firing direction 12 and has been positively guided in a linear manner since it has to move in the longitudinal groove (not shown) of the housing 14.

6a , 6b , 6c , 6d , 6e , 6f , 6g and 6h show the closure head 46 in a schematic representation in different views. The same objects are provided with the same reference numbers as in the previous figures. In the 6a and 6g A locking surface Y is shown in each case, which is required when assembling the locking device 44 into the handgun 10. A locking pin (not shown) is supported on the locking surface Y. In the 6b , 6d and 6f Driver surfaces Q can be seen on the side of the bolt head 46 facing the bolt carrier 48. The driving surfaces Q or stop surfaces Q prevent the breech head 46 from falling out of the breech device 44, in particular from the breech carrier 48, when installed in the weapon 10. These are chamfered surfaces that are attached to the closure head 46 in order to largely reduce possible bouncing behavior from the outset when the two opposing surfaces hit each other.

With X is in 6a , 6d and 6g each denotes the end face of the control cam 79, which leans against or is supported on the locking carrier 48 in the unlocked state of the locking device 44. A feed surface Z on the control cam 78 is designed so that when the cartridge 62 is to be removed from the magazine, it can be pushed out of the magazine via the feed surface Z and the cartridge 62 does not jam. The front control surface 86 of the control cam 79 can be seen.

The surfaces S1 and S2 are each a right surface (S1) of the control cam 78 and a left surface (S2). The distance between S1 and S2 is designated R. R therefore corresponds approximately to a width of the longitudinal groove 76 in the locking piece 68 and in the housing 14, in which the control cam 78 is positively guided when the shot breaks. More information about this will be described in connection with the following figures.

The width of the width R of the control cam 78 corresponds approximately, especially with the necessary tolerances, to the distance between the magazine lips. During the loading process, the control cam 78 can pass through the magazine lips. It is therefore obvious that the width of the control cam 78 corresponds to the distance between the magazine lips.

In 6h the closure head 46 is shown and the position of the angles α and β is shown. A normal 6 is aligned perpendicular to the central axis 5. The angle α is formed between a tangent on the control surface 80 of the control cam 78 and the central axis 5, the angle α being formed between the central axis 5 and the tangent when viewed in the firing direction 12. A tangent on the control surface 86 of the control cam 79 and the central axis 5 enclose the angle β, the angle β between the central axis 5 viewed against the firing direction 12 and the tangent being formed. The tangent applied to the control surface 80 of the first control cam 78, 78a, 78b, which is designed as an inclined surface, and projected onto the central axis 5 defines the first angle of inclination α to the central axis 5. The angle of inclination α corresponds to the angle of inclination of the oblique groove 80 to the central axis 5 as seen in the firing direction 12 .

The control surface of the control cam 79, 79a, 79b, designed as a second inclined surface 86, defines the angle β, the tangent applied to the second inclined surface 86 and projected onto the central axis 5 as seen against the firing direction 12 defining the angle of inclination β.

The amount of the inclination angle α and the amount of the inclination angle β are preferably between 30° and 60°, in particular they are approximately 45°. α = - β applies, since the angle α is included in the firing direction 12 to the central axis 5 and the angle β is included opposite the firing direction 12 to the central axis. The sum of the amounts of the angles α and β is preferably 90°.

7 shows a schematic representation, in half section, of the locking device 44 installed in the housing 14 of the handgun 10. The same objects are provided with the same reference numbers as in the previous figures. The housing 14 is cut open on the vertical central plane and thus the view of the locking device 44 in the handgun 10 is released. The through-loading unit 42 has a driver nose 42a. The through-loading unit 42 is guided in the groove 71. Visible are the longitudinal groove 76' in the lower region of the housing and the longitudinal groove 76 in the upper region of the housing. The longitudinal grooves 76 and 76' serve to guide the bolt carrier 48. The bolt carrier is positively guided by the longitudinal grooves 76 and 76' and can only carry out a linear movement. This is the case, for example, if the shot breaks or a cartridge 62 is loaded.

The locking piece 68 is shown in half section. The locking device 44 is shown in the locking position, in particular the basic position. Furthermore, the bobbin 66 can be seen without winding.

8th shows a schematic view of the components - seen in the direction of flight 12 of the projectile - of the handgun 10: the spring device 60, the bolt carrier 48, the bolt head 46 and the cartridge 62. The same objects are provided with the same reference numbers as in the previous figures. The spring device 60 exerts a force on the closure device 44 in the firing direction 12. If the shot breaks and the locking device 44 moves backwards against the shot direction 12, the spring device 60 is compressed and the kinetic energy is stored.

9 shows a schematic representation in a side view (lower part of 9 and in a sectional view along arrow A (upper part of 9 ) a section of the handgun 10 in the area in which the locking device 44 is installed. The closure device 44 is not installed in the illustration. The control groove 76 can be seen in the sectional view. The longitudinal groove 76 or control groove 76 extends over the housing 14 and at least partially over the locking piece 68. The longitudinal groove 76 or control groove 76 has a linear section 90, the linear groove 90, and an oblique section 92, the oblique groove 92.

When the locking head 46, driven by the ignition of the propellant charge and its expansion, is forced to move backwards against the firing direction, the at least one control cam 78 of the locking head 46 moves in the locking piece 68, in particular along the obliquely extending section 92 of the oblique groove 92. As a result, the closure head 46 is forced into a rotational movement in addition to its longitudinal movement. The closure head 46 thus simultaneously performs a linear movement against the firing direction 12 and a rotary movement. The closure head 46 carries out a superimposed linear movement and rotational movement. In the seamlessly adjoining linear groove area 90, the locking head 46 then changes from a rotational movement with superimposed linear movement already within the locking piece 68 and then in the longitudinal groove area 76 of the housing 14 to a pure linear movement on its way backwards against the firing direction 12. The movement of the closure head 46 is positively guided in such a way that the movement of the closure head 46 is predetermined radially at any time t depending on its position in the longitudinal direction 5 or axial direction 5.

10 shows a schematic representation of the handgun 10 with the same section as in 9 . The closure device 44 is installed in the illustration. Can be seen in the upper part of 10 the front control cam 78, 78a, the linear groove 90 and the oblique groove 92. Due to the selected cutting profile, only a part of the locking carrier 48 is designated by the reference number 48, namely the entire upper rib of the locking carrier 48, which is accommodated in the linear groove 90, and is recognizable. The locking device 44 is unlocked and the distance A` between the locking head 46 and the locking carrier 48 can be seen (lower part of the picture).

In 11 the locking device 44, in particular the locking head 46, is shown in the basic locking position in the handgun 10 in a schematic, isometric representation. The control cam 78, 78a can be seen in the oblique groove 92 of the locking piece 68, with its control surface 80 on the corresponding one rear control flank in the oblique groove area 92 of the locking piece 68 rests without play. At this stage, the closure head 46 is at the beginning of the rotary movement and the linear movement against the firing direction 12 at time t=0. The amount of radial movement of the closure head 46 results from the angle α.

12 shows a different view of the locking piece 68 and the locking device 44 than in 11 . The illustration is shown slightly obliquely from the back above. The locking head 46 is largely covered in the illustration by the locking piece 68, which is why the reference number 46 is directed to the area next to the control cam 78, which is formed in one piece with the locking head 46. The oblique groove 92 in the locking piece 68 with the control cam 78 arranged in it can be seen here.

The areas designated with lower case letters a, b and c are described below. An offset marked c is due to the representation. The edges of the control cam 78 and the locking piece 68 are actually aligned. Area a is higher than area b.

The locking device 44 is in the (just) unlocked position in the lock return on its way to the rear. The control cam 78 of the locking head 46 has left the oblique groove area 92 and has reached the area of the linear groove 90. An end face SVT of the lock carrier 48 is behind a rear end face X of the control cam 79.

This can also be the closure device 44 in the closure advance in its closing movement. The control cam 78 of the closure head 46 has reached its front end of the linear groove area 90 in its linear movement range 90 and abuts the corresponding front control edge of the oblique groove area 92 with its front control surface 87. This indicates a rotational movement on the closure head 46. It can be seen that the left-hand rotation of the locking head 46 initiated by the front control surface 87 of the control cam 78 cancels the 90° rear position at the rear end The closure head 46, which is designed in one piece with the control cam 78 and control cam 79, is converted into a rotary movement which is superimposed on the linear movement. The control cam 79 slips into the recess on the lock carrier 48.

The closing spring 60 pushes the locking head 46 further linearly forward via the locking carrier 48. Due to the geometric design of the oblique groove 92, the control cam 78 guided therein and thus the locking head 46 are forced into a superimposed rotary movement until its abutment base 82 rests on a cartridge 62 and on the adequate control flank of the oblique groove area 92 in the locking piece 68 with its control surface 80 .

The angle of inclination α between the first rear control cam surface 80 of the first control device or a control flank of the locking piece 68 and the central axis 5 is particularly preferably directed opposite a possible twist angle of a weapon barrel 34, so that any radial force components that may occur during the shot development and act on the handgun 10 are around the Central axis 5 can be compensated.

13a and 13b show a housing section 14 'of the housing 14 of the handgun 10. Shown is a in 1 shown mechanical interface 17 to the fire control unit 40. The mechanical interface 17 can be combined with an electrical and / or electronic interface 94 and is generally referred to as a combined interface 94. Furthermore, line guides 102, 98, 96 from the operating window 30 to the interface 94, as well as line guides 103, 102, 98, 96 from the trigger mechanism to the interface 94 are shown. The programming coil 66 is only shown as a coil former without winding, the coil 66 also being connected to the line guide 96. The cable guide 96 designates a cable guide 96 in a cable channel formed within the housing structure 14. An exchangeable, in particular one-piece cable harness 96 is preferably arranged in the cable duct. The cable routing 98 is the preferred cable routing 98 when setting up a combined mechanical and electrical and/or electronic interface 94 for attaching the aiming aid 40 in general, in particular the fire control unit 40, to the handgun 10, which is intended to enable the exchange of energy and information between the components. The line 98 and/or line routing 98 can be a short connection of the electrical and/or electronic components of the combined interface 94. In this case, the cable guide 98 connects the interface 94 to the line 96, in particular to the cable harness 96.

The line guides 96, 98, 102 and 103 show electrically conductive areas 96, 98, 102 and 103 or partial areas that are permanently connected to the housing structure 14 and/or replaceable. The electrically conductive areas 96, 98, 102 and 103 are protected from external influences and run within the housing 14. The electrically conductive areas 96, 98, 102 and 103 connect electrical and/or electronic functional areas with each other. This means that preferably no further interfaces are necessary. The electrically conductive areas 96, 98, 102, 103 are designed in one piece, for example as a cable harness. The control element 30, which is preferably attached on both sides, is connected to the electrically conductive areas 96, 98, 102. Sensors 100, which query the weapon function, in particular query relevant positions, for example in the area of the trigger mechanism, are also connected to the electrically conductive areas 103, 102, 96, 98. A battery arranged, for example, in the area of the handle cover 18 can also be electrically connected directly to the electrically conductive areas 103, 102, 96, 98.

In 13b , which shows the handgun 10 in a top view, a vertical line area 102 can be seen. In this area, the interface 17, 94 is connected to the fire control computer 40. The vertical line area 102 can be seen.

The operation of the handgun 10 is described below. The various functional phases in a cycle from the basic position ready to fire, in which the cartridge 62 is fed, until the cartridge 62 is fed again are summarized and explained as follows.

initial position

• • Cartridge 62 is fed and rests with its front stop surface against the adequate stop in the cartridge chamber 64,
• • Butt surface 82 of the breech head 46 rests against the cartridge case of the cartridge 62 at the rear without play,
• • The contact surfaces 80 or control surface 80 of the front control cams 78, 78a, 78b of the locking head 46 rest on the adequate control flanks of the locking piece 68,
• • Due to the compressive force of the closing spring 60 acting on the locking carrier 48, its control flanks rest against the adequate front control surfaces 86 of the rear control cams 79, 79a, 79b of the locking head 46 without play,
• • The lower surface of the bolt carrier 48 rests on the top cartridge in the magazine 26 and presses it downwards against a feeder (not shown) and a magazine spring (not shown),
• • The interrupter pawl or first catch catch (not shown) was pushed out of the contact area with the hammer 23 by the locking carrier 48, so the first catch catch no longer blocks the hammer 23,
• • The hammer 23 is cocked and is only placed behind the second catch of the trigger 20.

Shot initiation

• • Ein Ziel wird über den Feuerleitrechner 40 aufgenommen,
• • Die Entfernung zum Ziel wird vermessen, wobei der entsprechende Mess-Befehl für den Feuerleitrechner 40 vom Bediener der Waffe 10 über eine Taste des Bedienfeldes 30 an den Feuerleitrechner 40 gesendet wird,
• • Die ermittelte Entfernung zum Ziel kann vom Bediener über eine Taste des Bedienfeldes 30 korrigiert werden,
• • Der Abzug 20 wird gezogen,
• • Der Feuerleitrechner 40 programmiert den Zünder des intelligenten Geschosses im Patronenlager 64 mit dem gewünschten Detonationspunkt auf der Flugbahn des Geschosses, kontaktlos über eine Spule oder über Kontaktpins und versorgt ihn gegebenenfalls auch mit Energie.

With the handgun 10 configured to program and fire smart ammunition, the following steps are performed:

• • A target is recorded via the fire control computer 40,
• • The distance to the target is measured, with the corresponding measurement command for the fire control computer 40 being sent to the fire control computer 40 by the operator of the weapon 10 via a button on the control panel 30,
• • The determined distance to the target can be corrected by the operator using a button on the control panel 30,
• • Trigger 20 is pulled,
• • The fire control computer 40 programs the detonator of the intelligent projectile in the cartridge chamber 64 with the desired detonation point on the trajectory of the projectile, contactlessly via a coil or via contact pins and, if necessary, also supplies it with energy.

• • Der Abzug 20 wird gezogen,
• • Die zweite Fangrast, insbesondere der Abzug 20 gibt den federbelasteten Hahn 23 frei,
• • Der Hahn 23 setzt sich in Bewegung,
• • Der Hahn 23 trifft den Schlagbolzen 50,
• • Der Schlagbolzen 50 bewegt sich nach vorne und dringt mit seiner Spitze ins Zündhütchen der Patrone 62 ein,
• • Der Schuss bricht,
• • Das Treibladungspulver wird gezündet und dehnt sich sehr stark aus.

When the weapon 10 is set up to fire inert ammunition and intelligent ammunition, the following steps are carried out, in particular one after the other:

• • Trigger 20 is pulled,
• • The second catch catch, in particular the trigger 20, releases the spring-loaded cock 23,
• • The tap 23 starts moving,
• • The cock 23 hits the firing pin 50,
• • The firing pin 50 moves forward and its tip penetrates the primer of the cartridge 62,
• • The shot breaks,
• • The propellant powder is ignited and expands greatly.

Unlocking process of the shutter

• • The bullet is pushed out of the cartridge case into the tube 34 by propellant gas,
• • The propellant charge also exerts a force directed backwards over the cartridge case towards the butt base 82 of the breech head 46,
• • The empty case is pushed backwards out of the cartridge chamber 64,
• • The extractor 81 sits loosely in the extractor groove,
• • The locking head 46 is thereby pushed backwards,
• • Due to its play-free support of its front control cams 78, 78a, 78b arranged in the first row 75 on the oblique control flanks of the locking piece 68, a rotational movement of the locking head 46 about its central axis 5 is simultaneously initiated,
• • Due to its control surfaces 86 of the control cams 79, 79a, 79b, which are arranged immediately behind it in the second row 75 ', rest against the bolt carrier 48 without play and are slanted in opposite directions relative to the front row 75, the bolt carrier 48 is pushed away from the bolt head 46,
• • Due to the geometrically opposite bevels 80 and 86 between the locking head 46 and the locking piece 68 as well as the locking head 46 and the locking carrier 48, the locking carrier 48 travels a further distance relative to the tube 34 and the weapon housing 14 per unit of time than the locking head 46,
• • The relationship between the bolt carrier path and the bolt head path relative to the barrel 34 or weapon housing 14 is directly proportional to the selected effective angles of the opposing inclined surfaces 80 and 86,
• • The resulting transmission ratio between the effective, opposing angles α and β in conjunction with a mass of the bolt carrier 48 must be coordinated with the impulse of the cartridge 62,
• • The inclined surfaces 80 between the control cams 78, 78a, 78b on the locking head 46 in the first row 75 and the control flanks on the locking piece 68 are further designed so that they are effective longer than the inclined surfaces 86 between the control cams 79, 79a, 79b on the bolt head 46 in the second row 75 'and the control flanks on the bolt carrier 48,
• • This ensures that the locking head 46 rotates a little further in a positively guided manner when the inclined surfaces 86 between the control lugs 79, 79a, 79b on the locking head 46 in the second row 75` and the adequate control flanks on the locking carrier 48 have already come to an end,
• • From this position, the bolt head 46 is positioned behind the front side (i.e. 90°) relative to the bolt carrier 48 and vice versa,
• • In this position, the locking head 46 is then fixed relative to the locking carrier 48, for example by a catch or preferably on the housing side in the longitudinal groove 76, 76 ',
• • This ensures that the breech - i.e. the breech head 46 to the breech carrier 48 - does not move during the breech return, the impact on the base piece, the reversal of direction and the feeding of a new cartridge 62 from the magazine 26 into the cartridge chamber 64 can lock or tilt “on the go” and/or tend to jam in the housing 14,
• • By moving the bolt carrier 48 backwards, a spring-loaded interrupter pawl (not shown) is released and the cock 23 is cocked,
• • The trigger pawl (second catch) and the interrupter pawl (first catch) can then set the tap 23 behind again.

Ejection of the empty case

• • The closure 44 moves further backwards with the sleeve and thereby tensions the closing spring further and further,
• • The empty cartridge case is pulled onto a stop fixed to the housing by the locking device 44 on the opposite side of the ejection window 32,
• • The sleeve is stopped abruptly at this point,
• • On the side of the ejection window 32, the spring-loaded extractor 81 attached to the bolt head 46 pulls the sleeve further backwards,
• • This initiates a lateral rotation or tilting movement of the sleeve in the direction of the ejection window 32,
• • The sleeve detaches from the locking head 46 and the extractor 81 and is ejected,
• • As soon as the locking device 44 leaves the area above the magazine 26, the top cartridge 62, which was previously blocked by the underside of the locking carrier 48, jumps up in the magazine 26 through a pre-tensioned magazine spring underneath and rests on the magazine lips,
• • This top cartridge 62 in the magazine 26 is therefore ready to be fed.

Further shutter rewind

• • The locking device 44 continues to run backwards,
• • The bolt carrier 48 hits the base piece or a bolt buffer,
• • The bolt carrier 48 is braked to a standstill and moved forward again by the force of the fully pre-tensioned recoil spring 60.

Shutter advance

• • The front control cam 78, 78a, 78b of the bolt head 46, which is at the 6 o'clock position, hits the rear of the cartridge 62, which is ready in the top position in the magazine,
• • This is pushed by the bolt head 46 out of the magazine 26 over the ascent ramp 70 towards the cartridge chamber 64,
• • The closure device 44 runs over the magazine 26 and places behind the subsequent cartridge 62 which jumps up in the magazine 26,
• • The upward movement of the upward-jumping cartridge 62 is limited by the underside of the bolt carrier 48.

Locking the shutter

• • The front control cam 78, 78a, 78b of the locking head 46, which is at the 12 o'clock position, is guided in the continuous upper guide groove 76 at any time t, the groove 76 running in the housing 14 and partly also in the locking piece 68,
• • If the upper front control cam 78, 78a, 78b of the locking head 46 at the front end of the essentially housing-side linear groove 92 with its front control surface 87 hits the front inclined region 92 of the control flank in the locking piece 68, this causes a rotary movement of the locking head 46 initiated around its central axis 5,
• • The frontal back position
• • The bolt head 46 continues to rotate in a forced manner until it comes to rest on the rear of the cartridge 62 already in the cartridge chamber 64,
• • Since the bolt carrier 48, which is pushed forward by the recoil spring 60, exerts a radial force via its control flanks via the rear control surfaces 86 on the control cams 79, 79a, 79b of the breech head 46, this is rotated about its longitudinal axis 5 in such a way that the front control cams 78 , 78a, 78b with the control surfaces 80 rest against the control flanks of the locking piece 68 without play,
• • In order to effectively prevent uncontrolled recoil or rebound of the closure 44, a recoil or rebound mass can preferably be placed in the closure carrier 48.

initial position

• • In the basic position of the handgun 10, the cartridge 62 is always automatically fixed without play between its stop in the cartridge chamber 64 and the butt base 82 of the breech head 46,
• • Even advanced wear or rough manufacturing tolerances are always automatically compensated for by the locking system 44,
• • This has a very positive effect on the precision of the handgun 10 as well as its durability,
• • The handgun 10 is loaded with a new cartridge 62 and is therefore ready for use again.
