description

technical field

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

State of the art

A firearm or handgun is a ballistic device in which a projectile is propelled by means of very rapidly expanding hot gases called propellant gases. The firearm typically has a barrel and a receiver, with the receiver being located in whole or in part behind the barrel. At its rear end, the barrel has a cartridge chamber for receiving a cartridge and an exit opening for a projectile of the cartridge arranged in front of the cartridge chamber. The housing typically includes 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 over other functions, such as loading, firing, securing and unloading the firearm.

Various breech mechanisms for firearms are known in the prior art, such as a tilting breech, a block breech, a cylinder breech, a toggle breech and/or a supporting flap breech. For semi-automatic firearms in particular, a Browning locking system, 1

CONFIRMATION COPY a mass closure and/or a roller closure, a closure driven by the tapped propellant charge gas, and a gas-braked closure are known. In the case of the mass breech, the mass of the mass breech used is set in relation to the strength of the cartridge used in order to ensure the breech function. In this case, the mass is typically designed in such a way that a safe firing is ensured, with the gas pressure acting backwards on the breech being sufficient to carry out at least the process of ejecting the cartridge case of the fired cartridge. In general, cocking a hammer of a trigger system of the firearm and reloading the firearm with a new cartridge are also performed. This is called a repeating process. A control of the closure device is achieved here in particular via the inertia of the closure.

A further development of a mass closure is the roller closure, which is structurally a deflected mass closure. There are known here rigid, so locked systems and semi-rigid systems. For example, the Swiss Army's assault rifle 57, the G3 rifle and the Heckler & Koch MP5 submachine gun use roller locks.

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.

The object is achieved by a locking device having the features of claim 1 and a handgun having the features of claim 22.

Advantageous configurations 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 in front of the bolt carrier is arranged, wherein the bolt head has a first control device and a second control device, wherein the first control device has at least one control lug and the second control device has at least one control lug, wherein the first control device with the at least one control lug is arranged at the front end of the bolt head and the second control device with the at least one control lug of the bolt head behind it is arranged on the breech head, wherein the at least one control lug of the second control device is in operative connection with the bolt carrier. The locking device is characterized in that the locking head is designed in one piece with the first control device and the second control device. In particular, the control lug of the second control device is operatively connected to a control flank of the bolt carrier. The control flank of the bolt carrier is preferably arranged on a side facing the bolt head, in particular a front side of the bolt carrier. The control lug 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 lug is arranged in the first row on the bolt head and the second control device with the at least one control lug is arranged in the second row on the bolt head. The first row is preferably arranged in front of the second row. In this case, the first row and the second row are preferably arranged at the front area of the closure head. The first row is particularly preferably arranged directly in front of the second row.

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

By arranging the at least one control lug of the second control device in the second row behind the first control device, the control lug of the second control device can be tilted with its sloping position when the handgun is in the ready-to-fire basic position The control surface rests against the associated inclined control flank on the bolt carrier without play. As a result, the bolt carrier can be pushed away from the bolt head by the movement of the bolt head. In particular, the bolt carrier can be pushed backwards.

In one embodiment of the closure device, the closure head is designed in one piece with the at least one control lug of the first control device and the at least one control lug of the second control device. In particular, the at least one control lug of the first control device and the at least one control lug of the second control device are formed on the closure head. As a result, the closure head with the at least one control lug of the first control device and the at least one control lug of the second control device can be produced simply and inexpensively. For example, the closure head with the control bosses of the first control device and the second control device can be manufactured in one piece as a milled part.

In one embodiment of the locking device, the locking head and the locking carrier are arranged axially one behind the other along a central axis of the locking device, so that when the locking head is subjected to an axial impulse, both the locking head and the locking carrier can be displaced along the central axis. In this case, the axial displacement of the bolt head can have a different amount than the axial displacement of the bolt carrier. The axial displacement is preferably decoupled.

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

The bolt head can have partial elements, which are called partial sections, which protrude into the bolt carrier and/or are movable in it. The closure head preferably has a first section and at least one second section. The first section is preferably a front section which is arranged on the side of the bolt head facing away from the bolt carrier. The second section preferably has a bolt head shaft. The second section can be accommodated in the lock carrier when the lock 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 bolt carrier can preferably move counter to the firing direction of the handgun, in particular move backwards. In this case, the second section is preferably moved out of the bolt carrier. In the unlocked state, the second section is arranged in sections between the first section of the bolt head and the bolt carrier. The bolt head shaft can be arranged on the second section.

In the context of the claims, an active connection is understood to mean a mechanical active connection. The operative 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 structurally specified. The control knob acts as the first component and forms a mechanical pairing with one of the control flanks assigned to it, which can act as the second component. This can be the pairing between the control lug and a control flank on the bolt carrier. In this case, the control flank on the bolt carrier essentially coincides with an associated control surface of the control lug; this is not a point or line contact, but preferably a surface contact. This has the advantage that large forces can also be transmitted and possible wear and tear can nevertheless be kept within limits. The control flank on the bolt carrier is aligned, at least in sections, essentially parallel to the associated control surface of the control lug. A movement of the control lug and/or the bolt carrier can preferably be initiated and/or stopped by the interaction of the control lug and the associated control flank on the bolt carrier. As a result, the control flank is preferably open to the front on the side facing the bolt head, the The control lug is arranged on the bolt head and a movement of the bolt carrier can thus be initiated. The movement of the bolt head and/or the bolt carrier can be positively guided by the interaction of the control lug and the associated control flank on the bolt carrier. In this case, further control elements, in particular stop surfaces or grooves, can in particular restrict, preferably restrict, the direction of movement of the bolt carrier and/or the bolt head.

The breechblock device may be a firearm breechblock device. In particular, the locking device is an improved geared mass lock. The advantage here is that the closure device is simple and robust. Furthermore, the closure device can have few components, in particular the closure device has no control pin. The locking device is free of control bolts. The function of the control bolt, as used in handguns according to the prior art, is in the locking device according to the invention by at least the front control lug and / or in particular the interaction between control lugs with inclined and parallel surfaces and the associated control flanks on the bolt carrier and / or taken over the locking piece and/or in the housing.

The control bolt is used in locking devices known from the prior art in order to control the movement of the locking head during operation of the handgun. The control bolt is a vulnerable component here, precisely because it is typically penetrated by a firing pin bore and is thus weakened and is shaped in line with the bolt carrier. Since the control pin is a relatively small component, it can also easily be lost when disassembling the bolt in the field. Furthermore, according to the state of the art, control bolts are often in operative connection with a sloping area of a lateral recess or pocket in the bolt carrier arranged perpendicularly to the firing direction during bolt return and/or bolt advance. This typically has the consequence that due to the inclined control area of the control cam, radial forces can always be transmitted to the bolt head via the control bolt during bolt return travel and/or bolt forward travel, and the bolt head and bolt carrier can thus become tense relative to the housing. At least the components involved are subject to significantly higher wear. Therefore, the advantage of the locking device according to the invention is a 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 knob. This can be done in particular by a rear control surface of the control lug of the second control device interacting with the bolt carrier. The The movement of the bolt carrier is preferably stopped in that the control lug can be supported on a surface of the bolt carrier. The bolt carrier preferably rests directly behind it on the at least one control lug of the second control device.

The bolt head is preferably arranged such that it can rotate and/or be linearly displaceable relative to the bolt carrier. The bolt head and the bolt carrier are particularly preferably arranged such that they can be displaced axially and/or radially in relation to one another. The bolt head and the bolt 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 bolt head and the bolt 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 lug can directly influence, in particular induce, the movement of the bolt head. The bolt head can be carried along by the movement of the cam. In particular, the movement and direction of movement of the closure head can be guided, in particular positively guided, by the control boss. There is preferably no relative movement between the at least one control lug 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 lug of the first control device and/or the control lug of the second control device.

In one embodiment of the locking device, in the case of the locking head the at least one control lug of the first control device is operatively connected to a locking piece, the locking piece being arranged in front of the locking head. The at least one control boss of the first control device is preferably in operative connection with at least one control flank formed on the locking piece. In particular, the at least one control knob is supported and guided on at least one control edge 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 bolt head, which can be initiated by a recoil, can be forced into a rotary movement of the bolt head by the geometry of the control lug of the first control device and the control flank of the locking piece. This advantageously results in a superimposed linear movement and rotary movement of the bolt head. The superimposed linear and rotary movement is preferably induced here by a linear, in particular axial, impulse that can be exerted on the closure head. In particular, the linear pulse can be caused by an expanding propellant charge.

In one configuration of the locking device, the at least one control lug of the first control device is positively guided in one end of the barrel, 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 point in time t, depending on its position in Longitudinal direction is predetermined radially.

In one embodiment of the locking device, the control lug has a first control surface which is arranged on a side facing the lock carrier and which has an inclined surface with an incline, the first control surface being able to slide along a front control flank of the locking piece. The control knob of the first control device is preferably guided by it. As a result, a rotary movement of the bolt head can be initiated. The inclination is preferably formed in the weft direction. The control surface is preferably substantially perpendicular to a horizontal central axis surface. The inclination is preferably formed to a normal surface of the central axis surface.

The control lug of the first control device preferably has a second control surface, with the second control surface being arranged opposite the first control surface of the control lug, with the second control surface of the control lug being in operative connection with the locking piece in such a way that a position of the bolt head is maintained at all times during locking - and unlocking process is predefined.

The control boss 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 boss facing away from the central axis.

The control boss of the first control device has the first inclined surface in its rear region, with 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 lug of the second control device has a control surface which is designed as an inclined surface with an incline in the opposite direction to the inclined surface of the control lug of the first control device. Opposite is to be understood as meaning that the inclination of the control surface of the second control device is oriented opposite to the firing direction, with the control surface of the control lug of the first control device being oriented along the firing direction. Here, the inclined surface can slide along a control flank of the bolt carrier.

In addition to the inclined surface, the at least one control lug of the second control device can form a stop surface which, in the unlocked state, strikes a front surface of the bolt carrier. This can stop a linear movement of the bolt carrier 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.

The control lug of the second control device preferably has a second inclined surface in its rear area, with the second inclined surface being able to slide along the control flank of the bolt carrier.

Preferably, a tangent applied to the control surface of the control lug of the first control device designed as an inclined surface and projected onto the central axis when viewed in the firing direction has a first angle of inclination a and a tangent applied to the control surface of the control lug configured as a second inclined surface and projected onto the central axis opposite to the firing direction Tangent has an angle of inclination ß.

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 ß can follow the relationship α = -ß. This enables the superimposed rotary and linear movement of the bolt head.

In one embodiment of the closure device, the total of the angle of inclination α between the first inclined surface and the angle of inclination β of the second inclined surface is approximately between 60° and 120°, in particular the sum of the amounts of α and β is equal to 90°. In this case, the angles α and β can assume different values, in particular they can be different. The first inclined surface and the second inclined surface are preferably arranged in opposite directions relative to a normal to the central axis. The sloping surface of the control lug of the first control device points in the firing direction and the sloping surface of the control lug of the second control device points in the opposite direction to the firing direction. Here, the normal to the central axis can be understood to mean the normal surface, the normal surface being aligned perpendicularly to a central axis surface running essentially horizontally through the central axis. The surfaces of the first control lug and/or the second control lug are preferably designed as a single or multiple trapezoidal, sawtooth or flat thread or partially as a trapezoidal, sawtooth or flat thread segment or sequentially as a trapezoidal, sawtooth or flat thread segment.

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

In one embodiment, the closure head is designed in one piece with the first control device and the second control device. The bolt head and the bolt carrier are particularly preferably connected to one another in a non-positive and/or positive manner.

A control lug of the bolt head can be in operative connection with one or alternately different of its 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 operative connection can be a forced operation. This allows the bolt head to be forced into a defined movement. For example, a linear movement of the breech head can be changed into a rotary movement by guiding the control surfaces of the control lug of the breech 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 used, an impulse that is triggered by the conversion of a propellant charge in a cartridge and separates a projectile from a cartridge case and accelerates it forward can be used to move the locking device or parts of the locking device. Here, in accordance with the conservation of momentum, the momentum of the projectile is partly absorbed by the housing and the shifting of the mass of the locking device into a taken in the 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 at a resulting speed in the opposite direction to the firing direction. The movement of the breech head is initially radial with a simultaneously superimposed linear movement. The movement of the bolt head is initiated by the interaction of the locking piece with the bolt head. The bolt carrier, which is in operative connection with the bolt head, moves exclusively linearly backwards, guided by at least one linear groove or longitudinal groove or edge on the housing. In this way, a spring element arranged behind the bolt 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 into its basic position, ready to fire.

During operation of the handgun, a breech-forward mechanism is provided, which can support the at least one control lug 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 edge on the locking piece is in particular an inclined control edge and can function as a control surface. As a result, the rotary movement of the breech head can be initiated, in particular the rotary movement of the breech head about a longitudinal axis of the breech head, in particular as long as the breech head moves simultaneously in the longitudinal direction in this area.

Due to the fact that 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 bolt head, the bolt carrier can cover a further distance per unit of time relative to the housing of the handgun than the bolt head. Here, the ratio of the bolt carrier travel and the bolt head travel relative to the housing is directly proportional to the effective angles α, β of the opposing bevels, in particular the beveled surfaces of the control lugs. The selection of the angles α, β determines the transmission ratio and is preferably matched 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 lug in addition to the at least one control lug. Here, the first control lug and the second control lug are preferably arranged rotationally symmetrically, preferably offset by 180° to one another. The first and second control knobs 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, ie in the 12 o'clock and 6 o'clock positions relative to one another. An extractor can be arranged on the breech head on one side offset by 90° to the two control lugs and can therefore be arranged horizontally in the 9 o'clock or 3 o'clock position within the weapon in the unlocked breech position. This has the great advantage that the ejection direction from the right side of the housing to the left side of the housing or from the left side of the housing to the right side of the housing can be easily changed by the shooter by simply rotating the bolt head by 180° around its longitudinal axis can be adjusted without tools. The bolt head is fixed in the preset position with regard to the selected ejection direction in the bolt carrier via a spring-loaded locking bolt. At the same time, this is the optimum mounting position in each case in order to be able to insert the breech into the weapon housing from behind. Furthermore, the control lug of the first control device in the 6 o'clock position in the unlocked breech position offers the great advantage that a cartridge can be pushed out of the magazine and placed in the cartridge chamber during the breech advance.

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 implemented.

Alternatively, however, four control knobs can also be provided, which are each arranged offset from one another by 90°. In the unlocked locking position, control knobs 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 lugs can also be arranged, which are also offset by 180° and arranged rotationally symmetrically to the bolt 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 lug in addition to the at least one control lug. The second control device is preferably arranged in the second row. The second control device is preferably arranged directly behind the first control device. In this case, the first control lug and the second control lug are preferably arranged offset radially by 180° with respect to one another.

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 bolt carrier, better, in particular more precise guidance can be implemented.

Alternatively, four control knobs can also be provided, which are each arranged radially offset from one another by 90°. As a result, the movement of the bolt head and the bolt carrier can be controlled more precisely. It is possible to prevent the components from tilting with one another and/or in the housing of the handgun. The symmetrical arrangement supports a smooth and tilt-free movement of the bolt carrier and the bolt head.

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

Due to the opposing bevels of the control knobs of the first control device and the second control device, a larger translation can be achieved. The translation of the first control device and the second control device can be realized by the configuration. As a result, the closure device, in particular the closure carrier, can advantageously have a small mass. In particular, with a cartridge of comparable caliber, a significantly smaller mass can be used than in mass locking systems according to the prior art. This makes it particular makes it possible to use larger and stronger calibers with the same or smaller mass of the bolt carrier in the bolting device in the case of the increased mass bolting with the bolting device according to the invention. 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 bolt carrier, the spring element being in an operative connection with the breech carrier when installed in the handgun, in particular being in direct operative connection with the bolt carrier.

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

The bolt head preferably has a rib-shaped thickening at least partially in the rear region, the rib-shaped thickening of the bolt head being able to be supported on the bolt carrier in such a way that the bolt head remains in operative connection with the bolt carrier inside the handgun. In particular, the bolt head always remains in operative connection with the bolt carrier, in particular at all times during the operation of the handgun. The bolt head cannot slip out of the bolt carrier. In particular, the second area or second section of the bolt head cannot slide out of the bolt carrier.

In one embodiment of the locking device, a breech head is formed on the breech head, with a cartridge resting without play on the breech head when the handgun is installed and ready to fire. The breech block is preferably formed on the front area of the bolt head facing the locking piece. The breech head of the breech head can rest against the cartridge and the cartridge can be clamped between a cartridge chamber and the breech mechanism without play. 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. As a result, the complete 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 breech spacing is the distance between a breech head of the breech head, i.e. the front contact surface of the breech head on the cartridge base, and a cartridge base of a case which is in contact with its front stop in the cartridge chamber. A cartridge case can always be automatically held or clamped between its front stop face in the cartridge chamber and the front face of the breech head by the locking device according to the invention. This preferably prevents uncontrolled, abrupt force peaks from occurring if the cartridge case were to hit the impact base surface of the breech head when the cartridge was fired. Thus, material protection of the components of the closure device is achieved and the durability is significantly improved. In addition, as a result of this feature of the locking device according to the invention, shooting tests show a significantly improved 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 when using the locking device, as the cartridge case is pushed out of the cartridge chamber by the gas pressure present. In particular, the extractor is subjected to less stress than in the case of prior-art locking devices. 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 for unloading the weapon.

In one configuration of the closure device, the closure head is designed in one piece with the first control device and the second control device. The closure head can preferably be manufactured and/or also printed as a milled part and/or turned part, in particular manufactured using 3D printing. As a result, the closure head can be guided, in particular forcibly guided, by means of the first control device and the second control device. Here, the control surfaces of the first control device with Control flanks of the locking piece are in operative connection and the control surfaces of the second control device interact with control flanks of the bolt carrier.

The bolt head and the bolt carrier are preferably connected to one another in a non-positive and/or positive 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 e.g. 1:3 or even less favorable and a very small taper, it tends to open as long as the propellant charge gas pressure is present. The cartridge case can be pressed against the internal geometry of the cartridge chamber by the internal gas pressure and can therefore not move longitudinally. Longitudinal grooves, referred to as relief grooves, are preferably arranged in the cartridge chamber, so that the cartridge case can be surrounded on all sides by the propellant charge gas pressure and the case can reliably drive the locking device according to the invention.

Due to the respective inclination of the control surfaces on the bolt head and the selection of the control surface angles α and β, it is possible that only partial components of the impulse are transmitted to the housing. This not only puts less strain on the handgun itself, but also on the shooter.

The relatively large incline of the sloping surfaces of more than approximately 30° is advantageous, since this can greatly reduce dependence on friction. Furthermore, foreign particles that have entered 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 locking head, locking carrier and control devices. Components of the closure device according to the invention do not have to be manufactured and adjusted with very high precision, as is the case with known roller closures, for example in the G3 rifle or the MP5 submachine gun. Occurs during long-term use of the invention If the locking device wears out, the new locking device automatically compensates for this.

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

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 as a result until the control surfaces of the bolt head in the first row touch the analogous control flanks in the locking piece come to the plant.

This can also prevent the bolt head from turning further. The bolt carrier holds the bolt head linearly and radially fixed in this position, preferably by the compressive force of the recoil spring applied to its rear, thereby ensuring that the cartridge or cartridge case is always clamped in the cartridge chamber without play.

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

There can therefore always be a gap or distance to 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 a steel part that is firmly anchored in the receiver while the bolt is being advanced, but rather an inclined surface on the bolt head and/or a cartridge case made of a rather soft case material, the risk of rebounding impacts on the bolt carrier can be greatly reduced. This is particularly advantageous, since a breech that bounces during the closing process can result in a serious malfunction of the weapon, especially in rapid firing sequences. The insensitivity of the closure device according to the invention to large tolerances and the automatic compensation of wear is preferably made possible and reinforced by the, in particular, very wide design of the control lugs in the first row and second row, since the wide design of the control lugs results in a relatively large, effective radial control path along the flank diameter of the control surfaces in radians.

The particularly wide design of the control lugs in the first and second row also brings with it a very great advantage for safety reasons, since the control lugs in the first row remain on the cartridge for a relatively long time when a cartridge is fired 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 so wide that they still fit horizontally between the magazine lips with the distance required for reasons of tolerance. In this context, 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 that faces the locking device. The magazine lips are preferably arranged on a longitudinal side that roughly corresponds to the length of the cartridge. The distance between the two magazine lips is preferably arranged symmetrically to the magazine housing when viewed horizontally from the side, so that the control boss of the first control device can pass through when it is in the 6 o'clock position.

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

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

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

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

The barrel may be a generally cylindrical tube. The inner tube geometry can be provided with a spiral 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 be used to hold a cartridge containing at least one projectile and a cartridge case. The tube is preferably made of a material which 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 bolt head and the bolt carrier are preferably arranged axially one behind the other and are operatively connected. In particular, they are arranged in a force-fitting and/or form-fitting manner, at least in some areas.

A locking piece is preferably arranged in front of the locking head on the pipe end, with 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 along the central axis and behind the bolt carrier of the bolting device, viewed counter to the firing direction, with the spring element in Is operatively connected to the closure device, in particular is directly operatively connected to the bolt carrier.

The spring element can be compressed by an axial movement of the breech head and the breech carrier, which are displaced axially 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 pushed forward axially.

The axial displacement of the locking device to the rear can preferably be implemented via the impulse introduction of the cartridge case onto the breech head 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 bolt carrier .

The handgun is preferably constructed in the AR15 or M4 design, in particular the necessary control elements are arranged as is 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 locking device is designed in particular for cartridge cases with a relatively large diameter-length ratio. In particular, cartridge cases without an extreme taper at a case mouth in the firearm can also be used 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 for firing intelligent ammunition. Projectiles from 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 munitions can be programmed using a laser range finder and ballistics computer to detonate in the air at a specific point on the trajectory. For example, this can hit an opponent behind a mound of earth. The range can be over 500 meters. The housing of the handgun is preferably designed as a one-piece lightweight construction and the housing has a magazine shaft, a connecting structure, a receiving structure for a fire control computer, a receiving structure for a trigger mechanism, preferably an ejection opening for cases and cartridges on both sides. Furthermore, a receiving structure for a pipe end and/or a locking piece are formed, in particular in one piece with the housing. Furthermore, a receiving structure for a handle cover is preferably provided. The one-piece lightweight construction can be made up of a thermoplastic and/or duroplastic matrix and reinforcing fibers.

In a preferred embodiment of the handgun, the housing comprises a plastic structure with a duroplastic 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.

In this case, 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 random order for component manufacture.

The use of the thermoplastic matrix, in particular with the fiber chips, has the advantage that the fiber chips can be recycled 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 reinforcement fibers allows the housing to be extremely rigid. Furthermore, the combination of matrix and reinforcing fibers enables the housing to be extremely strong. In addition, good damping properties can be realized.

In the manufacturing process, the matrix and the reinforcing fibers are pressed into the housing under pressure and at elevated temperatures in a largely automatic process. A 3D component is created, which is preferably produced 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. As a result, 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 interchangeable, electrically conductive areas or sub-areas that are protected from external influences and connect different 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 sub-areas can also be introduced permanently into the housing structure, preferably already 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 stored as a complete assembly in the Housing structure are attached.

In a further configuration 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 connection with a mechanical interface, in order to transfer information and/or energy between the handgun and external To be able to replace 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 manufacturing a handgun with a housing and a locking device, the housing can be made of a thermoplastic or thermoset matrix with reinforcing fibers are made by fiber chips are pressed under pressure and elevated temperature, with connecting parts, in particular Metallic connecting parts, for example the locking piece, can be integrated directly in the pressing process. In addition, fiber composite mats can be inserted partially or over the entire surface of 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. In this case, connecting parts, such as the locking piece, can preferably be integrated in the same process step. As a result, an automated manufacturing process for the housing of the handgun, the handgun housing is realized. This has the advantage of a cost-effective manufacturing process for the handgun, in particular for the housing.

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

Advantageously, a handgun that is as light as possible can be produced, which allows very compact external dimensions in relation to the cartridge diameter.

The essential elements of the preferred mode of operation of the locking device in the handgun are summarized below. In a basic position, the control surface of the first control device of the bolt head, which is formed in the firing direction, rests against the control flank of the locking piece. Due to the compressive force of the recoil spring, the bolt carrier rests with its control flank against the control surface of the bolt head, which is oriented counter to the firing direction, in particular without play. When the propellant charge is ignited and the gases in the propellant charge expand, an essentially axial force impulse is exerted on the breech head in the opposite direction to the firing direction. The bolt head is pressed against the firing direction. Due to the forced guidance of the control surfaces of the first control device of the bolt head on the control flanks of the locking piece, the bolt head is forced to rotate. At the same time, the bolt carrier is pushed away from the bolt head, since the control surfaces of the second control device slide along the control flanks of the bolt carrier. This movement of the bolt carrier continues until the control lug of the second control device is supported on the front end of the bolt carrier. This is initially the movement of the bolt carrier against the Firing direction stopped relative to bolt head. The bolt head rotates a little further, since 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 left the barrel. The closure device is pushed back into the initial position essentially by the stored kinetic energy in the closing spring.

At this point it is emphasized that, in addition to the previously described components of the locking device and the handgun, there are other components that are necessary for the function of the handgun and are not explicitly mentioned. These correspond to the components of a locking device and a handgun, as are described in the prior art. These are, for example, 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 description of the figures and the claims, the terms "front", "rear", top and bottom are used in the known form and in relation to a handgun that is used in the usual way. This means that the muzzle of the barrel is “in front”, that the breech device is moved backwards, in particular by the explosive gases, etc. The axial direction means the direction of the barrel axis (barrel axis), which is typically along the central axis .

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

character description

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

Figure 1 shows an isometric, schematic representation of a handgun 10 seen from above. The designations "front" and "back" as well as "in front" and "back" in the firing direction indicated by the 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 casing 18 on which a trigger guard 22 is attached. A fire selector lever 21 also projects out of the housing 14, preferably on the right and left side of the weapon housing. The trigger 20, a non-illustrated tap 23 (shown in Figure 2b) and the Fire selector lever 21 with a fire selector lever axis 21' together form a trigger mechanism.

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

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

A fire control unit 40 , which can be designed as a fire control computer 40 , is arranged geodetically above the housing 14 . Between the housing 14 and the fire control unit 40 is a load-through unit 42 or load-through mechanism 42 . The fire control unit 40 is mounted on a rail 17 or an alternative interface 17 or can also be attached directly to the weapon housing 14 .

In the housing 14 in the fully assembled handgun 10 in the area of Ejection window 32 arranged a locking device 44, not shown in Figure 1, which is described in more detail in the following figures.

Figure 2a shows the handgun 10 in a schematic representation in longitudinal section along the direction of fire 12. A center line 5 runs in the longitudinal direction essentially parallel to the direction of fire 12. The center line 5 runs in the center of the gun barrel 34 and the locking device 44. The trigger 20 is assigned to the hammer 23, which is in operative connection with the trigger 20. The axis 21' of the fire selector lever 21 can release or block the trigger 20.

In addition to the components of the handgun 10 identified in FIG. 1, individual parts of the locking device 44 can be seen in FIG. 2a.

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 detent that locks the firing pin 50 in its functional area is not shown in FIG. 2a. The bolt head 46 is arranged in front of the bolt carrier 48 . The firing pin 50 is arranged centrally in the breech head 46 and the breech carrier 48, in particular in a movable manner. The spring-loaded locking bolt runs in the bolt carrier 48 and essentially transversely to the central axis 5. A locking piece 68 is arranged in front of the bolt head 46. The locking piece 68 radially encloses a barrel 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 arranged radially 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 ladder 70 runs in the locking piece 68.

The bolt head 46 is arranged to be movable relative to the barrel 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 direction. When a projectile or cartridge 62 is fired, the breech head 46 can be displaced radially at least in some areas and at the same time superimposed in the horizontal direction axially to the rear, as long as the breech head 46 is aligned with an inclined groove area of the locking piece 68 is in operative connection. In this case, the movement of the closure device 44 takes place essentially along the arrow 12 and in the opposite direction to the arrow. More on this is described in the following figures. The locking piece 68 has control flanks that come into operative connection with control lugs (not shown) of the bolt head 46, namely when closing the bolt device 44 in the bolt forward movement in the firing direction 12 and when opening the bolt device 44 in the bolt return against the firing direction 12 if a shot is fired. In the area of the breech carrier 48 there is a recess or cut-out or cut-out 54 which serves to enable the hammer 23 to reach the firing pin 50 when the weapon is in the basic position 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 bolt carrier 48 (opposite the firing direction indicated by the arrow 12 ). Also shown are the cartridge 62, which is arranged halfway 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. The cartridge ascent 70 can also be seen. A cartridge 62 can get from the magazine 26 into the cartridge chamber 64 through the cartridge riser 70 .

Figure 2b shows a detail of the handgun 10 in a sectional view. Identical objects are denoted by the same reference numbers as in the previous figures. The locking device 44 can be seen more clearly. A driver surface Q can be seen on the bolt carrier 48 . A voltage supply unit, for example a battery, in particular a chargeable battery, can be provided in the handle cover 18 .

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

When the handgun 10 is in operation, 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 . In this case, 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 customary in known magazines. A longitudinal groove 76', which is arranged on the inner lower partial area of the housing 14, can be seen. The locking device 44 built into 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. In the area of the locking piece 68 facing away from the barrel 34, the longitudinal groove 76 merges into an oblique transverse groove (not shown). The longitudinal groove 76' is formed both in the lower area and in the upper area of the housing 14.

The longitudinal groove in the upper area is not shown in FIG. 3 and is denoted by reference numeral 76. The bolt carrier 48 can be positively guided by means of the longitudinal groove 76 and/or 76'. By means of longitudinal groove 76 and/or 76', but preferably longitudinal groove 76, which partially continues forward in firing direction 12 in locking piece 68 and merges into an oblique transverse groove 92 in the area of locking piece 68, locking head 46 of locking device 44 can be each position are forcibly guided. The longitudinal groove 76' is thereby interrupted by the cartridge feed opening 74. However, the locking piece 68 is not shown in FIG. The radial and linear orientation of the entire closure device 44 at any point in time t as a function of its position in the longitudinal direction along the center line 5 is predetermined here.

Also on the housing 14 is a receiving structure 77 for the trigger mechanism, which includes at least the trigger 20, the spring-loaded hammer 23, the fire selector lever 21 with fire selector lever axis 2T and the grip cover 18, preferably with the trigger guard 22 includes, which are shown in Figures 1 and 2, is provided. The receiving structure 77 can be shaped or designed in such a way that it can strengthen or stiffen the slotted area of the housing structure 14 in a weight-neutral manner, which is necessary for the hammer 23 of the trigger mechanism to be able to reach the firing pin 50 .

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

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

In particular, the receiving structure 77 for the trigger mechanism is molded on and is therefore formed in one piece with the housing 14 . A necessary longitudinal slit in the upper housing area, which ensures that the loading-through unit 42 can come into operative connection with the bolt carrier 48 when the weapon 10 is loaded through, is reinforced and stiffened by a composite structure 43 or overlapping 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 locking device 44 is positively guided in the opposite longitudinal direction and in the firing direction 12. A radial movement of the locking device 44 about its longitudinal axis 5 is prevented when the cartridge 62 is fired and the locking device 44 or the locking 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 to the housing structure 14 directly and in one piece and thus without play. However, the locking piece 68 can also be connected to the housing structure 14 without play via a holding structure that is connected directly and in one piece to the housing structure 14 and is therefore free of play. The housing structure 14 is at the Areas where recesses are arranged, reinforced by thickening. Thickenings and/or reinforcements mean, for example, double or multiple layers of fiber composite material.

The cartridge feed port 74 and/or a portion of the magazine well 24 are also integral with the housing 14 and/or molded thereto. In the housing 14 reinforcements by metal inserts, which are locally limited, are preferably arranged in areas that partially absorb large forces when firing.

Furthermore, known or future interfaces are provided or anchored on the housing 14 via which known or future accessories can be connected to the handgun 10 . These are, for example, aiming aids such as rear sight and front sight, laser 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 of an alternative material. The locking piece 68 is arranged and/or formed on and/or integrated at a front end of the housing structure 14 and is preferably connected in one piece to the housing part structure. Alternatively, the housing structure 14 can also be a tunnel-shaped or tubular partial structure reinforced and/or supplemented by a fiber composite structure and/or a plastic or metal structure.

The housing 14 or the housing structure 14 can be made of fiber composite material, with the locking piece 68 being arranged and integrated at its front end 15 in the interior 72 and preferably in one piece directly with the housing structure 14 without play or also via a holding body with this 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 designed to be extremely light. In the housing structure 14, only functionally absolutely essential openings are provided 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 74, which is preferably on the lower side of the weapon is arranged and a tap recess, which is preferably also arranged on the lower side of the weapon, introduced.

The slotted area extending longitudinally at the top, in which the loading-through unit 42 acts on the driver surface 85 of the bolt carrier 48 during the loading-through process through the housing structure 14, is also firmly closed by a composite structure 43 or overlapping structure 43 and so propped up.

To increase the buckling 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 matched to the respective partially acting forces with regard to strength, weight, costs and also haptics. A 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. At every point, the housing structure 14 is optimally matched to all load paths occurring during use in order to be able to design the housing structure 14 to be very stable and robust on the one hand and also very light on the other, ie without accumulating unnecessary weight. The housing structure 14 is therefore basically the same as the bionic structure, comparable to the trunk and root system of a tree or the structure of a bone.

Three design examples are listed below:

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 fabric structure with an optimized load path. Furthermore, the housing 14 has load-bearing and non-load-bearing filling and stiffening bodies laminated into it. The tube 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 manufacture of the housing structure 14 . Alternatively, a holding component made of metal for receiving the tube end 19 and/or the locking piece 68 is already laminated or glued into the fiber composite structure during the manufacture of the housing structure 14 .

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. At least the control flank area of the locking piece structure 68 or the locking piece structure 68 can be integrated directly 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 duroplastic and can be filled and unfilled.

3.) The housing 14 and/or housing structure 14 comprises a plastic structure of a thermoset and/or thermoplastic matrix and reinforcing fibers, the locking piece 68, the locking piece retaining component 68 and/or a conventionally constructed metal structure with locking piece 68 or a printed metal part, which is 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 at elevated temperature to form the complex housing structure 14, in particular pressed as a 3D molded part. As a result, series production is possible, a high level of reproducibility can be achieved and the housing 14 can be manufactured economically at low costs. Good damping properties of the housing 14 can be realized through the combination of matrix and reinforcing fibers. At the same time, the housing 14 has very good rigidity and strength properties. The thermoplastics polyamide (PA), polycarbonate (PC), PEEK, PEI, PPS and PES as well as some duroplastics 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 set almost as desired by the fiber length, the fiber type and the percentage of fiber volume.

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

Thermoplastic materials are preferably used for the matrix so that the fiber fragments 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 on the finished housing 14 to determine whether the housing structure 14 of the handgun 10 was produced using a method from a matrix with fiber snippets or fiber chips.

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

Recording structures for military and civil interfaces are embedded in the plastic structure of the weapon housing 14 analogous to the metal components described, such as the locking piece 68.

The design 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 in that the magazine shaft or at least a part of the magazine shaft is integrally formed on the housing structure 14.

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

In order to counteract a partial failure of the housing structure 14 in its construction from plastics) and/or fiber composite materials) and/or light metal, metal inserts, e.g. made of steel, are preferably introduced in areas in which partially applied large loads and forces act. in order to be able to introduce them into the housing structure 14 over a large area.

The handgun 10 with the housing 14 or the housing structure 14 has the guideway 71 arranged inside the housing structure 14, in which the through-loading unit 42 is accommodated 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 during the loading process moves out of the housing structure 14 backwards through-loading Unit 42 leads in whole or in part 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 of the weapon can be checked easily and in detail after the frame 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 grip casing 18 and is thus protected against external influences. The grip sleeve 18 is preferably slipped over the trigger mechanism mounted on the housing structure 14 and 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 receives a weapon barrel 34 directly or indirectly at its rear end 19 and permanently free of 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 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 off the housing inner structure 14 to the rear. This support plate or the bottom 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 space—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 exchangeable cartridge receiving magazine 26 and a very light and robust housing structure 14 with an overall width which corresponds approximately to twice the cartridge 0 and whose width is in the area of the handguard 38 encasing the weapon barrel 34 can be reduced to less than 1.3 times the cartridge 0, is characterized in that the handgun 10 can withstand the loads 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 grip casing 18), but also a bullpub design (magazine 26 behind the trigger 20 and the Handle shell 18 arranged) are constructed.

The handgun 10 with the housing 14 or the housing structure 14 and the locking device 44 can be configured in a manner suitable for an M4/M16 Operate in the usual way for shooters.

The housing 14 has a receptacle for a cable duct 73 in its upper area. Furthermore, the guideway 71 for the through-loading unit 42 is integrally formed on the housing 14 . A through-loading area 41 is shown in dashed lines. In the process, a charging lever 42' (not shown) is pulled out of the housing 14 and at the same time 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 .

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

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

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

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

FIGS. 4a and 4b each show two front control knobs 78a and 78b and two rear control knobs 79a and 79b. However, provision is also made for arranging four or more front control lugs 78 and four or more rear control lugs 79 on the bolt head 46 . Correspondingly, more control surfaces are then provided on the bolt carrier 48 . Thus, a pair of control flanks on the bolt carrier 48 is always assigned to a pair of control lugs 79 .

Furthermore, a spring-loaded extractor 81 is arranged on the bolt head 46 . The breech head 46 has an impact base 82 against which the cartridge 62 (not shown) can rest when the breech mechanism 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 breech head 46, the ejector being able to engage in the recess 83 when the breech device 44 is installed in the housing 14, as shown in FIG moved behind. Instead of the ejector fixed to the housing, a spring-loaded ejector mounted in the bolt head 46 can also be used.

A driver surface 85 can be seen on the upper part of the bolt carrier 48 , which is set up to establish an operative connection with the loading-through unit 42 .

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

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

FIGS. 5a (lock locked) and 5b (lock unlocked) show a schematic top view of the locking device 44. The control bosses can be seen 78, 78a and 78b in the front area 75 and thus in the first row on the bolt head 46 and the control lugs 79, 79a and 79b in the rear area 75 'in the second row on the bolt head 46 Control flank of the bolt carrier 48 has slid and the distance A' between the bolt head 46 and the bolt carrier 48 is now significantly greater than the distance A in FIG. 5a. The rear end X of the control lug 79 is supported on the bolt carrier 48, in particular on an end face SVT of the bolt carrier 48. In the unlocked state in FIG. It can be seen that due to a preceding combined rotational and linear movement of the bolt head 46, the control lug 79 is in a different position relative to the bolt carrier 48 in the unlocked state, radially and in the longitudinal direction. The bolt carrier 48 has moved in the opposite direction to the firing direction 12 and has been linearly forcibly guided since it has to move in the longitudinal groove (not shown) of the housing 14 .

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

X in FIGS. 6a, 6d and 6g designates the end face of the control lug 79, which leans against or is supported on the breech carrier 48 when the breech mechanism 44 is in the unlocked state. A feed surface Z on the control boss 78 is designed in such a way that when the cartridge 62 is to be removed from the magazine, it is fed over the feed surface Z can be pushed out of the magazine and the cartridge 62 does not jam. The front control surface 86 of the control boss 79 can be seen.

The surfaces S1 and S2 are a right surface (S1) of the control boss 78 and a left surface (S2), respectively. The distance between S1 and S2 is denoted by R. R thus corresponds approximately to a width of the longitudinal groove 76 in the locking piece 68 and in the housing 14, in which the control boss 78 is positively guided when the shot breaks. More on this is described in connection with the following figures.

The width of the width R of the control boss 78 corresponds approximately, in particular with the necessary tolerances, to the distance between the magazine lips. During the loading process, the control boss 78 can pass through the magazine lips. Thus, it is obvious that the width of the control boss 78 corresponds to the spacing of the magazine lips.

The locking head 46 is shown in FIG. 6h and the position of the angles α and β is indicated. A normal 6 is aligned perpendicular to the center axis 5 . The angle a is formed between a tangent on the control surface 80 of the control boss 78 and the central axis 5, the angle a being formed between the central axis 5 and the tangent as seen in the firing direction 12. A tangent on the control surface 86 of the control boss 79 and the central axis 5 enclose the angle β, the angle β being formed between the central axis 5 seen against the weft direction 12 and the tangent. The tangent projected onto the central axis 5 and projected onto the control surface 80 of the first control boss 78, 78a, 78b defines the first angle of inclination a to the central axis 5. The angle of inclination a corresponds to the angle of inclination of the inclined groove 80 to the central axis 5 in the firing direction 12 .

The control surface of the control boss 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 in the opposite direction to the weft direction 12 defining the angle of inclination β.

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

FIG. 7 shows a schematic representation, in half section, of the locking device 44 installed in the housing 14 of the handgun 10. Identical objects are provided with the same reference symbols as in the preceding figures. The housing 14 is cut open on the vertical center plane and the view of the locking device 44 in the handgun 10 is thus released. The through-loading unit 42 has a driver lug 42a. The through-loading unit 42 is guided in the groove 71 . The longitudinal groove 76' in the lower area of the housing and the longitudinal groove 76 in the upper area of the housing can be seen. The longitudinal groove 76 and 76' serve to guide the bolt carrier 48. The bolt carrier is positively guided by the longitudinal groove 76 and 76' and can only perform a linear movement. This is the case, for example, when 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 coil body 66 can be seen without a winding.

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

Figure 9 shows a schematic representation in a side view (lower part of Figure 9 and in a sectional view along the arrow A (upper part of Figure 9) of a section of the handgun 10 in the area in which the locking device 44 is installed. The locking device 44 is not built in. The sectional view shows the control groove 76. 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.

If the bolt head 46, driven by the ignition of the propellant charge and its expansion, is forced to move backwards in the opposite direction to the firing direction, the at least one control lug 78 of the bolt head 46 moves in the locking piece 68, in particular along the obliquely running section 92 of the oblique groove 92. This forces the bolt head 46 to rotate in addition to its longitudinal movement. Thus, the bolt head 46 performs a linear movement counter to the firing direction 12 and a rotary movement at the same time. The closure head 46 performs a superimposed linear movement and rotational movement. In the seamlessly adjoining linear groove area 90, the bolt head 46, on its way backwards in the opposite direction to the firing direction 12, then changes from a rotational movement with a superimposed linear movement already inside the locking piece 68 and then in the longitudinal groove area 76 of the housing 14 to a pure linear movement. 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 point in time t depending on its position in the longitudinal direction 5 or axial direction 5 .

FIG. 10 shows the handgun 10 in a schematic representation with the same section as in FIG. 9. The locking device 44 is installed in the representation. The front control lug 78, 78a, the linear groove 90 and the inclined groove 92 can be seen in the upper part of FIG is received in the linear groove 90 and can be seen. 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 figure).

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

FIG. 12 shows a different view of the locking piece 68 and the locking device 44 than in FIG. The representation is shown at a slight angle from behind and above. In the illustration, the locking head 46 is largely covered by the locking piece 68, which is why the reference number 46 is directed to the area next to the control boss 78, which is designed in one piece with the locking head 46. Visible here is the oblique groove 92 in the locking piece 68 with the control boss 78 arranged in it.

The areas a, b and c denoted by the lower-case letters are described below. An offset marked c is due to the presentation. In reality, the edges of the control knob 78 and the locking piece 68 are aligned. Area a is higher than area b.

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

This can also be the closing movement of the closing device 44 in the closing movement. The control lug 78 of the bolt head 46 has reached its front end of the linear groove area 90 in its linear range of movement 90 and strikes with its front control surface 87 against the corresponding front control flank of the inclined groove area 92 . As a result, a rotary movement on the locking head 46 is indicated. It can be seen that the left rotation of the bolt head 46 initiated by the front control surface 87 of the control lug 78 cancels the 90° rear position at the rear end X of the control lug 79 relative to the bolt carrier 48 . The locking head 46, which is designed in one piece with the control lug 78 and control lug 79, is converted into a rotary movement that is superimposed on the linear movement. the Control lug 79 slides into the recess on bolt carrier 48.

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

The angle of inclination a between the first rear control boss 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 in the opposite direction to a possible twist angle of a weapon barrel 34, so that any radial force components that may occur during the development of the shot and act on the handgun 10 around the Central axis 5 are compensated.

Figures 13a and 13b show a housing section 14 'of the housing 14 of the handgun 10. Shown is a shown in Figure 1 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 commonly referred to as the 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 shown only as a bobbin without a winding, with the coil 66 also being connected to the lead wire 96 . The wiring 96 designates a wiring 96 in a cable duct formed within the housing structure 14 . An exchangeable cable harness 96, in particular a cable harness 96 designed in one piece, is preferably arranged in the cable duct. The line guide 98 is the preferred line guide 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 guide 98 can be a short connection of the electrical and / or be electronic components of the combined interface 94. In this case, the line 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 which are permanently connected to the housing structure 14 and/or can be replaced. The electrically conductive areas 96, 98, 102 and 103 are protected from external influences and run inside the housing 14. The electrically conductive areas 96, 98, 102 and 103 connect electrical and/or electronic functional areas to one another. As a result, 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 operating 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 querying 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 grip cover 18 can also be electrically connected directly to the electrically conductive areas 103 , 102 , 96 , 98 .

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

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

initial position

• Cartridge 62 is fed and its front stop surface is in contact with the appropriate stop in chamber 64,

• The breech face 82 of the bolt head 46 rests against the cartridge case of the cartridge 62 without play. • The contact surfaces 80 or control surface 80 of the front control lugs 78, 78a, 78b of the bolt head 46 rest on the appropriate control flanks of the locking piece 68,

• Due to the compressive force of the recoil spring 60 acting on the bolt carrier 48, the latter rests with its control flanks on the adequate front control surfaces 86 of the rear control lugs 79, 79a, 79b of the bolt head 46 without play,

• The bolt carrier 48 rests with its lower surface on the top cartridge in the magazine 26 and presses it down against a follower (not shown) and a magazine spring (not shown),

• The breaker pawl or first catch detent (not shown) has been pushed out of the area of contact with the hammer 23 by the bolt carrier 48, so the first catch detent is now no longer behind the hammer 23,

• The hammer 23 is cocked and is only set back in the second click of the trigger 20.

shot initiation q

With the handgun 10 set up to program and fire smart munitions, 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 by the operator of the weapon 10 to the fire control computer 40 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,

• The trigger 20 is pulled,

The fire control computer 40 programs the fuze of the intelligent projectile in the cartridge chamber 64 with the desired detonation point on the projectile's trajectory, contactlessly via a coil or via contact pins and, if necessary, also supplies it with energy.

In the case of a weapon 10 set up for firing inert ammunition and for intelligent ammunition, the following steps are carried out, in particular one after the other:

• The trigger 20 is pulled, • The second catch, in particular the trigger 20 releases the spring-loaded hammer 23,

• The cock 23 starts to move,

• The hammer 23 hits the firing pin 50,

• The firing pin 50 moves forward and penetrates the cartridge primer 62 with its tip,

• the shot breaks,

• The propellant powder is ignited and expands greatly.

Entrieqelunqsvorqanq the closure

• The projectile is pushed out of the cartridge case into the tube 34 by the propellant gas,

• The propellant charge exerts a force that is also directed backwards via the cartridge case, in the direction of the breech head 82 of the bolt head 46,

• The empty case is pushed backwards out of the chamber 64,

• The extractor 81 sits loosely in the extractor groove,

• This pushes the bolt head 46 backwards,

• Due to its play-free support of its front control lugs 78, 78a, 78b arranged in the first row 75 on the oblique control flanks of the locking piece 68, a rotary movement of the bolt head 46 about its central axis 5 is initiated at the same time,

• The bolt carrier 48 is pushed away from the bolt head 46 by its control surfaces 86 of the control lugs 79, 79a, 79b, which are arranged directly behind it in the second row 75', rest against the bolt carrier 48 without play and are inclined in the opposite direction to the front row 75,

Due to the geometrically opposite bevels 80 and 86 between the breech head 46 and the locking piece 68 as well as the breech head 46 and the breech carrier 48, the breech carrier 48 covers a further distance relative to the barrel 34 and the weapon housing 14 per unit of time than the breech 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 a and ß in connection with a mass of the bolt carrier 48 must be matched to the impulse of the cartridge 62,

• The inclined surfaces 80 between the control lugs 78, 78a, 78b on the bolt head 46 in the first row 75 and the control flanks on the locking piece 68 are also designed so that they are longer effective than the inclined surfaces 86 between the control lugs 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 bolt head 46 is forced to continue rotating a little when the inclined surfaces 86 between the control lugs 79, 79a, 79b on the bolt head 46 in the second row 75' and the appropriate control flanks on the bolt carrier 48 have already come to an end,

• From this position, the bolt head 46 is rearranged at the front (i.e. 90°) relative to the bolt carrier 48 and vice versa,

• In this position, the bolt head 46 is then fixed relative to the bolt carrier 48, e.g. by a catch or preferably in the longitudinal groove 76, 76' on the housing side,

• This ensures that the breech - i.e. the breech head 46 to the breech carrier 48 - does not move during the breech return, when it hits the receiver, when the direction is reversed and when a new cartridge 62 is fed from the magazine 26 into the cartridge chamber 64 can lock or jam "on the way" and/or tend to jam in the housing 14,

• By moving the bolt carrier 48 to the rear, a spring-loaded breaker pawl (not shown) is released and the hammer 23 is cocked,

• The trigger pawl (second catch) and the interrupter pawl (first catch) can thus set the hammer 23 back again.

Ejection of the empty case

• The breech 44 runs further backwards with the case and always preloads the recoil spring,

• On the opposite side of the ejection window 32, the empty cartridge case is pulled by the locking device 44 onto a stop fixed in the housing, • 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 case further backwards,

• This initiates a lateral turning or tilting movement of the case towards the ejection window 32,

• The case detaches from the bolt head 46 and the extractor 81 and is ejected in such a way that

• As soon as the breech mechanism 44 leaves the area above the magazine 26, the uppermost cartridge 62 in the magazine 26, which was previously blocked by the underside of the breech carrier 48, jumps up in the magazine 26 due to a pretensioned magazine spring underneath and rests against the magazine lips,

• This top cartridge 62 in the magazine 26 is thus ready for delivery.

Another shutter return

• The locking device 44 runs further backwards,

• The bolt carrier 48 strikes the base piece or a bolt buffer,

• The bolt carrier 48 is braked down to a standstill and is moved forward again by the force of the fully pretensioned recoil spring 60 .

Shutter advance

• The front control lug 78, 78a, 78b of the bolt head 46, which is at the 6 o'clock position, hits the rear of the cartridge 62 that is in the uppermost position in the magazine.

• This is pushed by the bolt head 46 out of the magazine 26 over the ascent ramp 70 in the direction of the cartridge chamber 64,

• The locking device 44 runs over the magazine 26 and places behind the following cartridge 62 jumping up in the magazine 26,

• The upward movement of the bouncing cartridge 62 is limited by the underside of the bolt carrier 48.

locking the breech

The front control lug 78, 78a, 78b of the bolt head 46, which is at the 12 o'clock position, is in the continuous upper guide groove at all times t 76, with the groove 76 running in the housing 14 and partly also in the locking piece 68,

• If the front control surface 87 of the upper front control lug 78, 78a, 78b of the bolt head 46 at the front end of the linear groove 92, which is essentially on the housing side, hits the front inclined area 92 of the control flank in the locking piece 68, this causes a rotary movement of the bolt head 46 initiated around its central axis 5,

• The back position X between the control lugs 79, 79a, 79b of the bolt head 46 in the second row 75' and the bolt carrier 48 is thereby canceled,

• The breech head 46 continues to rotate under forced control 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 pressed forward by the recoil spring 60, exerts a radial force through its control flanks via the rear control surfaces 86 on the control lugs 79, 79a, 79b of the bolt head 46, this is rotated about its longitudinal axis 5 in such a way that the front control lugs 78 , 78a, 78b with the control surfaces 80 without play on the control flanks of the locking piece 68,

In order to effectively prevent the breech 44 from rebounding or rebounding in an uncontrolled manner, a recoil or rebound mass can preferably be placed in the breech 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 breech plate 82 of the bolt head 46,

• Even advanced wear or rough manufacturing tolerances are automatically compensated by the locking system 44,

• This has a very positive effect on the precision of the handgun 10 and its durability,

• The handgun 10 is loaded with a new cartridge 62 and is therefore ready for use again. Reference character list
