Description

Field of the Invention

The present invention relates to a through-loading device of a self-loading firearm according to the preamble of claim 1.

The invention also relates to a self-loading firearm equipped with such a through-loading device.

In these documents, positional designations such as "top", "bottom", "front", "back", etc. relate to a self-loading firearm in which the soul axis runs horizontally and the shot is fired away from the shooter.

A through-loading device is used for loading a self-loading firearm using a through-loading lever in order to put it into a ready-to-fire state. The functional sequence for shooting and automatic reloading in a self-loading firearm can be simplified as follows:
A longitudinally movable breech arrangement is provided in the weapon housing for firing the shot, pulling out a shot cartridge case and reloading it. To fire the shot, the breech assembly, in particular its breech head, introduces the top cartridge from the magazine into a cartridge chamber in the tube in a known manner. When a trigger mechanism is actuated, a firing pin hits the bottom of the cartridge and ignites a propellant charge there, so that a projectile is fired from the cartridge case through the tube. As well as the projectile Drilled hole in the gun barrel, the propellant gases released during the shooting process can be branched off into a gas take-off in a gas pressure loader. The branched propellant gases are used to cause the closure arrangement to move backwards in a known manner. The propellant gases drive the locking arrangement towards the rear at high speed via the gas take-off and a gas linkage connected to it.

An extractor is provided on the breech head, which grips a cartridge case at its edge on the base of the case and pulls it out of the cartridge chamber when the breech arrangement moves back. An ejection device then pushes the cartridge case out of the weapon housing in a known manner via a cartridge ejection window. When the locking arrangement returns, it slides back over the magazine towards the shaft. During the subsequent advance of the breech arrangement, the breech head in particular now grips the top cartridge from the magazine again and feeds it into the chamber and the cycle is repeated. Alternatively, a recoil loading mechanism can be used in a known manner for this cycle.

To feed a cartridge, the top of the magazine rear wall and the magazine front wall are each recessed at their upper end over a certain distance. The side walls of a magazine are extended upwards and form so-called magazine lips, which prevent the cartridge from falling out of the magazine. A spring arranged in the magazine pushes the cartridge feeder inside the magazine housing upwards and this pushes the cartridges up to the magazine lips.

In so-called shooting self-loading firearms, the breech (breech carrier and breech head) is in its forward position before the shot fired previously, i.e. the breech head is locked to the cartridge chamber. After inserting a first or possibly a new magazine into the self-loading firearm, the loading mentioned above is carried out.

In the case of a so-called closing closure, the closure can be moved into a rear position by means of the loading lever, in which it is caught by the trigger mechanism.

Known through-loading devices are often attached to the closure and by grasping the loading lever, the closure can be moved backwards, that is to say in the direction of the shaft, so that the closure is moved backwards against the force of the closing spring via the magazine. When the breech is advanced, the breech head takes the top cartridge out of a magazine and introduces it to the front of the cartridge chamber.

A through-loading lever which is firmly coupled to the closure is provided, for example, in the known G36 from the applicant or also in the known SA 80. Such a loading lever is also referred to as a moving loading lever because, due to the coupling with the closure carrier, it also participates in the previously described forward and return movement. If the loading lever protrudes from the weapon, there is a risk of injury to a rifle. If the protruding charging lever hits an obstacle, this can lead to loading inhibitions. Such a fixed mounting on the breech is known today for both military and civil self-loading rifles.

Also not included are through-loading levers from the AR15 variants such as the one HK 416/417 known to the same applicant. In addition, it is known that the loading lever on the loading device can be assembled and disassembled without tools.

Even before the First World War, through-loading devices were developed in which the loading lever decouples from the lock after loading. Because of this decoupling, the closure, in the event that it should not close properly, cannot be closed with the aid of the loading lever.

Through-loading devices in various designs are known overall, these can also have a loading lever which is provided either on the right or on the left side of the weapon.
For example, from the DE 101 22 345 C1 the same applicant has known a one-sided and one-sided operated, non-rotating cocking slide, in particular for the M64, by means of which the closure against the pressure of a closing spring is biased. A longitudinal slot is formed in the housing with a clamping rail in which the tensioning slide is guided and can be fixed.

From the DE 10 2006 006 034 B3 The same applicant also knows a through-loading device, for example for the HK416, in which the through-loading lever can be operated on both sides using two handles, either on the left or on the right. Activation of one handle automatically releases the second handle from locking the weapon in order to carry out a through-loading process.

Furthermore, from the EP 0 489 024 B1 the same applicant a loading device for self-loading handguns, in particular for the known G36, with a pivotable and lockable loading lever known. This is arranged directly or via an intermediate piece on the breech and can be pivoted out of the weapon housing on both sides of the longitudinal axis of the breech.

In the case of military weapons, the boundary conditions that occur during use, such as ambient temperature, weapon temperature, contamination, continuous fire and the like, are increasingly changing. As a result, a cartridge may not be fully fed when it is inserted into the cartridge chamber, or it may cause an inhibition of loading in some other way. In the event of an escapement, however, the locking system can often no longer be closed properly without additional manipulation, which leads to a danger to the shooter. Such escapements are extremely rare, but in principle a military weapon should be as free from interference as possible. In such cases, the closure can often be operated manually by means of an appropriate loading device, thereby eliminating any inhibition of charging.

From the US 7,798,045 B1 a through-loading device with a through-loading lever that does not follow is known, the through-loading lever being provided with handles protruding on the left and right sides. This cannot be dismantled without tools and cannot be operated either on the left or right side. The through-loading device comprises a carriage which has a catch hook on its end facing the closure carrier, which engages in a corresponding recess on the closure carrier in order to to guide it towards the cartridge chamber as a locking aid.

From the U.S. Patents 9,109,848 B2 , US 8,156,854 B2 and US 8,561,517 B2 Through-loading devices are known which cannot be mounted on the left or right side without tools. The self-loading firearm disclosed therein comprises a weapon housing and a hand guard coupled thereto, the through-loading device being guided in the hand guard. The loading lever can be pivoted between a rest and actuation position, and in the actuation position it engages with a recess in the gas piston rod both during loading and in its function as a closing aid. The loading device therefore does not act directly on the closure carrier. In an alternative embodiment, the through-loading device is provided with actuating handles configured on both sides.

The US 8,307,747 B2 discloses another non-rotating through-loading device with a through-loading carriage with a spring-loaded catch nose for engagement with the closure carrier. The loading lever is rigidly on the side of the weapon. In its function as a locking aid, the catch engages in the lock carrier and leads it forward. The US 8,539,871 B1 shows a similar through-loading device.

The FR 1,349,766 and the parallel German patent DE 1 208 221 disclose a through-loading device with a through-loading carriage that does not follow and is provided that can be coupled directly to the closure carrier via a locking pin. The through-loading device is arranged on the top of the weapon and comprises a spring-loaded central clamping handle, which acts either purely spring-loaded via a threaded connection or a pivotable lever on a locking member and transfers it from a rest position into its operating position, in which the cocking slide can be coupled directly to the breech block. This through-loading device cannot be converted without tools for optional right-hand or left-hand operation.

Furthermore, the DE 199 03 321 A1 and the parallel US 2002/0046642 A1 the applicant of the same name a loading lever arrangement for a handgun. Of the Charging lever can be converted without tools, is mounted directly in the lock, and is therefore designed to follow. The loading lever cannot be swiveled and therefore projects laterally from the weapon.

The EP 0 207 058 B1 discloses a non-rotating through-loading device with a non-convertible, laterally pivotable one-sided loading lever. When loading, the loading lever acts on the end of a longitudinal guide rod of the lock via a slide. In its locking aid function, the loading lever also engages with the longitudinal guide rod via the slide.

Finally the US 3,686,998 a swiveling through-loading lever that does not run along with the loading. A slide acts directly on the closure. When used as a locking aid, the swiveling loading lever is positively locked with a locking extension via a slot on its axis and a hook provided on it. Disassembly without tools is not intended.

Object and solution of the invention

Against this background, it is the object of the invention to provide an alternative, structurally simple and functionally reliable through-loading device for a self-loading firearm.

This object is solved by the subject matter of independent claims 1 and 19, respectively.

The through-loading device of a self-loading firearm mentioned at the outset is additionally distinguished by the fact that the loading lever handle can be pivoted from a rest position into an actuating position and vice versa in the loading lever holder, and the loading lever holder in the loading lever housing can be mounted and dismantled without tools either on the left or on the right.

The self-loading firearm according to claim 19 is characterized in that it is equipped with such a through-loading device.

The loading lever holder in the loading lever housing can advantageously be mounted or removed on the left and / or right side. In particular due to the tool-free assembly and disassembly option, a through-loading device that can be operated either on the left or right side of the weapon can be provided with structurally simple means, which can be adapted to the ergonomics of the shooter and thus in particular to a left-handed or right-handed person. The ability to be used from both sides is a criterion that is often required today in government tenders.

In addition, the through-loading device, in particular the through-loading lever, can be ergonomically optimally positioned in comparison to the loading lever housing, so that the self-loading firearm can be held well in the target during the through-loading process and can also be operated while lying down without increasing the body signature. Charging activities can also advantageously be carried out in the secured state of the self-loading firearm, with safety in particular being guaranteed.

In a structurally simple embodiment, the loading lever handle is provided in the loading lever holder so as to be pivotable about a bearing axis between its rest position and its actuation position. In a simple embodiment, the loading lever axis can be provided as a pin.

The loading lever handle can have a profiled surface in order to improve its grip, in particular under difficult conditions and / or with gloves. The loading lever handle can also be provided at least in whole or in part with a casing and / or profile elements. A rubberized coating in particular improves the feel. Such a sheathing material can also be provided as a buffer material.

The loading lever handle is preferably pretensioned on the loading lever holder in its rest position.

In a technically or structurally simple embodiment, it is prestressed by an elastic element, for example a spring element.

Preferably, when loading the self-loading firearm, only one contact surface of the loading lever holder and / or one end face or end face of the loading lever housing is detachably connected to the breech.

The breech can be moved backwards in the direction of the barrel of the weapon when loading through the contact surface or the front surface of the loading lever housing. This is advantageously only a positive connection and additional coupling elements, as in the prior art, can be avoided. It is also ensured that the closure and the loading lever holder or the loading lever housing and thus the entire loading device can only be releasably connected to one another during loading, but not when shooting.

It is therefore preferred that when the self-loading firearm is fired, the through-loading device is completely separated from the breech.

Advantageously, the charging lever remains in its position when shooting. This measure increases the security of the shooter, especially in stressful situations. On the other hand, a shooter also has unlimited hold and stop options. Such a loading lever is referred to as a non-moving loading lever. In comparison to a moving through-loading lever, for example in the known G36 from the applicant or the known SA80, injuries to the shooter due to the moving through-loading lever can be avoided.

Since the through-loading device is completely separated from the breech carrier, it is also guided separately and can be locked in the weapon housing.

For this purpose, at least one locking element is preferably provided on the loading lever, which is designed for locking on or with a counter-locking on the weapon housing, so that the loading lever can be fixed on the counter-locking.

In a structurally simple embodiment, the latching element can be provided, for example, as a latching lug on the loading lever, in particular on the inside thereof, which faces the weapon housing.

The locking element is preferably provided on the loading lever handle and serves to engage with a counter-locking provided in the weapon housing and designed to be complementary thereto, for example also a locking lug. Since the loading lever or its loading lever handle is prestressed in its rest position, it preferably lies in this position on the weapon housing, its latching nose being in engagement with the counter-latch on the weapon housing. In this way, it can advantageously be ensured that the through-loading device is fixed to the weapon housing during the closing movement, in particular when firing, that is, it does not run with it. In the rest position, the loading lever lies flat on the side.

The loading lever housing can be solid. It is preferably penetrated by at least one recess formed in its longitudinal direction, which is provided in particular for receiving a gas piston rod.

In addition, further recesses can be provided, which serve in particular to save weight on the loading lever housing. The recess in the longitudinal direction for the gas piston rod is approximately complementary to the outer dimensions of the gas piston rod.

The through-loading device is preferably provided so that it can be manually fed into a cartridge chamber in a cartridge chamber on the self-loading firearm, in particular on the gas piston rod.

After fixing it to the gas piston rod, the through-loading device can be moved forwards towards the cartridge chamber via the loading lever, which automatically moves the bolt coupled to the gas piston rod towards the cartridge chamber.

This function serves as an integrated closing aid and in particular for the manually supported feeding of a cartridge into the cartridge chamber. Because the through-loading device is disconnected from the lock, a connection or coupling is required for this manual locking function.

The locking aid function is used to eliminate malfunctions, for example loading inhibitions, or for quiet closing.

In the actuation position, the loading lever handle can be acted on in the direction of the weapon housing in the locking aid function.

The through-loading device can be fixed on the gas piston rod by means of suitable coupling measures.

The through-loading device preferably comprises an engagement element for engagement with at least one recess in the gas piston rod, the engagement element being provided so as to be adjustable between an engagement position and a release position.

In the operating position of the loading lever handle, this can be acted upon in the direction of the weapon housing. In a simple embodiment, the engaging element can be provided, for example, as a spring-loaded locking pin, the outer dimensions of which are approximately complementary to the recess in the gas piston rod and, in the engaged position, reach through the loading lever housing or the slide and thus fix the loading lever on the gas piston rod locked.

For this purpose, the engagement element is preferably biased into its release position via an elastic element.

The elastic element can be a suitable elastic means, in particular a spring.

In the engaged position, the loading lever is in its pivoted-out or pivoted position, that is to say the actuating position, in which it is transverse to the direction of firing is folded down. The charging lever can be fixed in this position via the engagement position.

If, for example, the breech is released from its rear position with an extended and fixed loading lever that is in the engaged position, the loading lever housing can strike a fixed stop in the weapon housing with its front stop. This ensures that the loading lever automatically folds down and engages again with the counter-latch on the weapon housing after it has been pivoted into its rest position, in which it extends parallel to the weapon housing.

Preferably, the loading lever handle is only displaceable and / or pivotable in its engagement position only in the actuating position in the loading lever holder.

This measure ensures that no unintentional connection with the gas piston rod is created.

Preferably, the loading lever handle is pivotally articulated at its end facing the loading lifting housing about a position axis provided in the loading lever holder between its rest position and its actuation position and, in particular, comprises an elongated hole which surrounds the bearing axis and extends in the actuation position approximately transversely to the longitudinal direction of the through-loading device.

This measure ensures that the position axis is guided in the slot.

In the rest position, the elongated hole extends approximately parallel to the weapon housing and in its actuation position at approximately a 90 ° angle to the firing direction.

Preferably, the loading lever handle is pivotable between its rest position and its actuating position about the end of the elongated hole facing the loading lever housing, and when the loading lever handle is moved in its engagement position within the elongated hole, it is displaceable such that the bearing axis is on the end of the slot opposite the loading lever housing comes into contact.

This measure can be provided with structurally simple means and ensures that the entire loading lever handle can be pushed into the loading lifting holder in the defined position approximately over the entire length of the elongated hole and thereby displaces the loading lever handle over a defined distance.

The loading lever handle preferably comprises a locking catch on its end facing the loading lever housing for engagement with the engagement element in the rest position. When the loading lever handle is pivoted into the actuating position, the locking catch disengages from the engagement element and pivots and / or shifts the engagement element in the direction of the loading lever housing.

The end of the loading lever handle facing the loading lever housing can e.g. be rounded and have a locking recess which is in engagement with the engagement element in the rest position. For this purpose, the engagement element can be provided in a structurally simple configuration, for example as a locking pin or bolt. The locking position prevents unintentional actuation in the rest position.

In the case of a design as a locking pin or bolt, the underside of the pin can have an inclined wedge surface which cooperates with the end of the loading lever handle such that when it is pivoted it engages the wedge surface and pivots or displaces the locking pin or bolt in the direction of the gas piston rod . In the actuating position, which is additionally combined with the engagement position, the locking pin can then be acted upon or displaced relative to the gas piston rod such that it engages with the recess provided there.

The loading lever housing preferably has at least one receiving bearing on both sides for receiving and coupling the loading lever holder.

With this measure, structurally simple means can be used to define a repeatable use position of the loading lever holder with the loading lever handle coupled to it establish. The loading lever holder can be inserted into the receiving bearing from the side. Alternatively, the loading lever holder can also be inserted from the rear or from the front into corresponding guide sections in the loading lever housing, depending on where the receiving bearing is provided on the loading lever housing.

The loading lever holder is preferably provided such that it can be latched on the loading lever housing, in particular on the receiving bearing.

In a structurally simple embodiment, for example, a spring-loaded pin or bolt can be provided for this. This measure can be securely locked in place using structurally simple means of the loading lever holder.

The loading lever holder preferably has a spring-loaded dismantling element, the actuation of which in a dismantling position cancels the latching of the loading lever holder on the loading lever housing.

For example, the dismantling element can be provided as a dismantling slide, when it is actuated or pulled out of the loading lever holder, preferably against the force of a spring, the latching of the loading lever holder on the loading lever housing can be released.

The loading lever housing preferably comprises on both sides at least one guide section for engaging and guiding in complementary guide rails in the weapon housing.

At least two guide sections are particularly preferably provided on both sides, in order to enable a two-point guidance of the loading lever housing. For example, the guide sections can be provided in the manner of a groove in the loading lever housing and have internal dimensions that are approximately complementary to the guide rails.

A stop element with a buffer element for abutment against a fixed stop in the weapon housing is preferably provided on the loading lever housing. At the Lock advance strikes the loading lever housing at the fixed stop in the weapon housing.

The buffer element serves to reduce the impact forces and can be provided from a suitable buffer material.

Guide rails for guiding the breech carrier each extend over at least one guide section provided on both sides of the breech carrier and for guiding the loading lever housing over the at least one guide section thereof, which is formed on both sides, in the interior of the weapon housing on both sides in the longitudinal direction of the weapon housing.

The guide rails can be formed in one piece during manufacture of the weapon housing, for example in aluminum extrusion. However, they can also be retrofitted into the weapon housing.

A recess is preferably provided at least on one side of the weapon housing, through which the loading lever holder coupled to the loading lever handle can be inserted or removed in the loading lever housing for assembly or disassembly and is guided there during loading.

Recesses are particularly preferably provided on both sides as guide slots in the weapon housing. On the one hand, these can be formed using structurally simple means and serve to accommodate the loading lever holder and loading lever handle. With a complementary design of guide sections on the loading lever holder, they can also be used to guide the through-loading handle within the weapon housing. The loading lever is installed, for example, through a window in the weapon housing or via the receptacle, for example on a T-slot in the loading lever housing. At least one counter detent is preferably provided on the weapon housing, on which the loading lever can be fixed during the locking movement.

In another embodiment, the counter detent can be provided as detents on the weapon housing that are complementary to the detent element on the loading handle.

The structure and the mode of operation of the through-loading device according to the invention are explained below with reference to the figures.

The reference symbols are not inserted throughout in all figures in order not to impair the clarity. However, the same reference numerals apply to all figures.

The through-loading device 1 according to the invention essentially comprises the following components: a through-loading lever 13, 13 ', which is assembled from a loading lever handle 15 and a loading lever holder 17 and can be coupled to a carriage or a loading lever housing 59, 59', which is in a weapon housing 3 is performed.

Figures 16 a to 19b show, inter alia, elements of a self-loading firearm required for the function of the through-loading device 1, which in the present case is intended as an assault rifle, namely the HK433 of the applicant.

The HK433 is a so-called indirect gas pressure charger with a short-stroke gas piston system and a lockable turn-lock lock. After firing the shot, the short-stroke gas piston system transmits an impulse via a gas rod to a breech block. A short-stroke gas piston is characterized by a short movement path, which is sufficient to transmit a corresponding drive pulse to the gas linkage or the closure arrangement. The short-stroke gas piston is not firmly connected to a gas linkage of the closure arrangement. The breech comprises a breech carrier 119 and a breech head 172. The breech carrier 119 is guided in a longitudinally movable manner within the weapon housing or its upper part 3 in a known manner.

Figures 16a to 17b show the loading device 1 in its rest position, in which the loading lever housing or the slide 59, 59 'rests with its rear end (contact surface 121 of the loading lever holder 17) on the front end of the closure carrier 119 (cf. Figures 17a and 17b ). The loading lever handle 15 is located near the front end of the guide slot 7 in the weapon housing 3 and is locked there via a locking lug 23 on its inside 22 with a complementary counter-locking 24 on the weapon housing 3. The closure carrier 119 is in its foremost position, in which the closure head 172 is locked in the cartridge chamber 155 (cf. FIG. 17a). In this position, a magazine (not shown) can now be inserted into the self-loading firearm from below in a known manner.

In order to now insert a cartridge (not shown) into the cartridge chamber 155, that is to put the self-loading firearm in a ready-to-fire state, the through-loading device 1 can be actuated. For this purpose, a shooter grasps the loading lever handle 15 of the loading lever 13, 13 'and folds it backwards from the self-loading firearm so that in its actuation position it protrudes sideways to the upper part 3 of the weapon housing at an angle of approximately 90 degrees (cf. Figure 18b and 19b ).

The through-loading device 1 can now be moved backwards in the direction of the shaft (not shown) via the loading lever handle 15, the loading lever handle 15 acting on the carriage or loading lever housing 59, 59 ′ resting on the front of the closure carrier 119 and thus on the carriage or the loading lever housing 59 , 59 'and thus the closure carrier 119 against the force of the closing spring 161 (cf. Figures 17a and 17b ) leads backwards. The loading lever housing or the carriage 59, 59 'is guided in the weapon housing 3.

In Figures 18a to 19b the closure carrier 119 and the through-loading device 1 guiding it are in their rearmost position. When the closure carrier 119 is brought into this position, the closure head 172 has slid over the magazine, as described at the beginning. During the subsequent advance, he can grip a cartridge (not shown), lead it out of the magazine and insert it into the cartridge chamber 155. During the forward movement of the loading device 1 and the closure carrier 119, the loading lever handle 15 of the loading lever 13, 13 'folds. back towards the gun housing 3 and lands again in its starting position or rest position (cf. Figures 16a and 16b ), in which the closure head 172 is locked in the cartridge chamber 155 in a known manner. The weapon is now ready to fire.

In the event of an escapement, if an automatic closing of the locking system or locking bracket 119 should not be possible, a shooter can also use the loading lever handle 15 within the loading lever holder 17 and in the gas piston rod 111 via a locking aid pin 125 (cf. Fig. 6c and 8th ) in a recess 127 provided on both sides in the gas piston rod 111, so that the loading lever handle 15 does not automatically pivot into its rest position, but is fixed at an approximately 90 degree angle. A shooter can then pass through-loading device 1 to the front via loading lever handle 15. The loading lever handle 15 pivots back into its rest position only when it is carried out from its locked position or strikes a fixed stop 109, which is secured to the weapon housing 3 by a fastening screw 6, during the breech advance (cf. Figures 4a to 6a and 9 ).

The loading described above is now described in detail using all the figures:
Figure 1 a shows an enlarged detailed view of the weapon housing 3. The upper part of the weapon housing 3 is made monolithically from a high-strength aluminum and has an integrated Picatinny rail 5 on its upper side, for example according to NATO standards. For example, sighting devices and / or night vision devices can be mounted on the Picatinny rail 5. Within the weapon housing 3, the breech carrier 119 is guided in a known manner as in the applicant's G36, so that functional reliability and reliability of the self-loading firearm is ensured.

On the underside 9 of the upper part 3 of the weapon housing, receptacles 11 are provided for fastening the handle and hand protection in a known manner. In the longitudinal direction of the upper weapon housing part 3, guide slots 7 are provided on both sides, within which the through-loading device 1 or its through-loading lever 13, 13 ′ can be moved. The loading lever 13 (13 ') includes the loading lever handle 15 and the loading lever holder 17. The details of which are particularly shown in FIGS Figures 2a and 2 B shown enlarged. Of the Loading lever holder 17 can optionally be mounted or removed on the left and / or right side of the self-loading firearm without tools. It is inserted in the carriage or loading lever housing 59 (59 ') (cf. enlarged detail representations of the embodiment in FIGS Figures 3a and 3b ).

In Figures 1a and 1b is the loading lever 13 in its rest position, in which it is locked on its inside 22 extending towards the weapon housing 3 towards the weapon housing 3 with a complementary counter-locking 24 on the weapon housing upper part 3. Due to this latching, the loading lever 13 (13 ') is fixed on the upper part 3 of the weapon housing, so that it does not follow a locking movement, but rather the locking carrier 119 can move independently and freely.

The inner end of the 20 of the loading lever handle 15 is pivotally mounted within the loading lever holder 17 (see here Figures 2a and 2 B and 4a to 6c, 10 and 11).

Since the loading lever 13 (13 ') in its rest position lies flat against the side of the weapon housing 3 and is locked there, it is also referred to as a non-rotating loading lever 13 (13'). Since it does not follow, the loading lever 13 (13 ') remains in its locked rest position when the shot is fired (cf. Figures 1a and 1b ). The fixed through-loading lever 13 (13 ') increases the safety of a shooter and prevents possible injuries. The shooter is also not restricted in any holding and firing positions of the self-loading firearm. The loading lever 13 (13 ') can be converted without tools from the left to the right side of the weapon and can therefore be provided so that it can be operated on the left or right side. In addition, the through-loading lever 13 (13 ') has a locking aid function for quietly feeding a cartridge into the cartridge chamber 155 (cf. inter alia Fig. 6c and 8th ).

Figure 2a shows a first embodiment of a loading lever 13 and Figure 2b a second embodiment 13 '. The loading lever 13, 13 'is shown in its rest or starting position and has approximately the shape of a lying "L". The long leg of the "L's" forms the loading lever handle 15, which can have a rubberized casing 21 which extends in whole or in part over its outer holding and gripping section. The loading lever handle 15 comprises an external one End 19 and an inner end 20. On the inside 22 of the loading lever handle 15, that is to say on the side facing the weapon housing 3 in the assembled state, there is a detent 23 for loading lever locking on the weapon housing 3, as described at the beginning.

The outer outer side facing away from the weapon housing 3 comprises two surfaces 25, which are approximately wedge-shaped and extend in the longitudinal direction of the loading lever handle 15. These surfaces are also beveled towards the outer end 19 of the loading lever handle 15 downwards via wedge-shaped surfaces 27. At the lower front end, the outer end 19 of the loading lever handle 15 runs approximately semicircularly over a rounded underside 29 to the inner side 22.

The inner end 20 of the loading lever handle 15 is arranged within a slot 39 in the loading lever holder 17 so as to be pivotable about a loading lever axis 31. For this purpose, an elongated hole 33 (cf. Figures 4c , 5c , 6c and 8th ) the inside in the longitudinal direction of the loading lever handle 15. The slot 39 passes through the loading lever holder 17 horizontally such that the loading lever handle 15 from its starting position or rest position, in which it rests on the weapon housing upper part 3 and is locked there, by about 90 degrees in one Actuating position is pivotable, in which it protrudes at approximately a right angle from the upper part 3 of the weapon housing. The guide slot 39 is limited at its outer end by a stop 40, which also limits the pivoting movement of the loading lever handle 15.

Adjacent to the stop 40, a disassembly slide 43 is provided within the outer contour or the surface 37 of the loading lever holder 17, which is mounted transversely to the longitudinal direction of the loading lever holder 17 to the outside, that is to say displaceably away from the weapon housing upper part 3. The top and bottom of the disassembly slide 43 is provided with a profile structure 44 in order to enable better gripping, in particular, for example, in the event of contamination or with gloves.

The removal slide 43 can be removed from the outside 37 of the loading lever holder 17 against the force of a removal slide spring 45 for removing the loading lever 13, 13 '(cf., inter alia, 4c, 5c and 6c). In the loading lever holder 17, the dismantling slide 43 is in its interior via a bearing pin 123 (cf. also Figure 8 , Figure 4c , 5c , 6c , 12b, 12c and 13 ) coupled with a locking pin 51. The locking pin 51 is slidably mounted within a bore 53 within the loading lever holder 17. The bearing pin 123 passes through the locking pin 51 approximately vertically. Adjacent to the bearing pin 123, the end of the locking pin 51 towards the outside 37 of the loading lever holder 17 is approximately in the form of a pin and thus forms a bearing 124 for the dismantling slide spring 45. The bore 53 is provided as a blind bore, so that the dismantling slide spring 45 engages with the other End supported on the bottom of the blind bore 53 and the locking pin 51 of the disassembly slide 43 in the direction of the weapon housing upper part 3 towards the inside. This is done in such a way that the locking pin 51 as in FIG Figure 2a shown, protrudes from the underside of the loading lever holder 17, which faces the weapon housing upper part 3.

The operation of the locking pin 51 and that of the disassembly slide 43 are explained below. In the surface 41 of the loading lever holder 17, a circumferential recess 47 is provided in the direction of the underside 50 thereof, which engages the loading lever holder 17 within the slide 59 (59 ') (cf. Figure 3a and 3b ) enables. The loading lever holders 13, 13 ′ rest in the guide slots 7 of the weapon housing 3 with their guide surfaces 46 (see Fig. 2a , 2 B , 7 , 10th , 13 , 20a , 20b and 20c ) Towards the end 50 there are 17 locking lugs 49 on the outer peripheral surface of the loading lever holder. The two outer locking lugs 49 extend all around the outer contour of the loading lever holder 17 and the middle locking lug 49 is also formed on the opposite side or underside of the loading lever holder 17, not shown.

The locking lugs 49 are dimensioned such that they have locking lugs 85 of complementary dimensions in the bearing 83 via the loading lever holder 17 (cf. Figure 3a ) fit together in such a way that the loading lever holder 17 can be inserted from the outside onto the slide or the loading lever housing 59 into the bearing 83. The locking lugs 49 of the loading lever holder 17 slide past the locking lugs 85 of the slide or the loading lever housing 59 until they are brought into abutment with the bearing 83. In this position, the disassembly slide 43 must additionally be brought outwards against the force of the disassembly slide spring 45, so that the locking pin 51 no longer protrudes over the end or underside 50 of the loading lever holder 17, but is located completely within the loading lever holder 17. Now the loading lever can be moved backwards until its rear end or the rear detent 49 within the bearing 83 is completely stopped.

In this position, the detents 49 are arranged offset to the detents 85 to the rear, that is, they are positioned behind them. The locking pin 51 is located opposite a bore 87 provided in the carriage or loading lever housing 59, 59 '(cf. Fig. 3a and 3b ). In this position, the removal slide 43 no longer protrudes from the outer contour 37 of the loading lever holder 17 ( Fig. 2a ), the locking pin 51 dips with its front end into the bore 87, locked there and so the loading lever holder 17 is fixed in this position. The disassembly slide is then in his again Fig. 2a shown starting position. The dismantling slide spring 45 is relaxed.

Figure 2b shows a second embodiment of the loading lever 13 according to the invention, which also includes a loading lever handle 15 and a loading lever holder 17. The structure and mode of operation are essentially identical to that in Figure 2a Charging lever 13 shown. The charging lever handle 15 differs from the first embodiment in that it has a slightly modified outer contour in which the front beveled wedge-shaped surfaces 27 are designed to be somewhat longer. On the inside 22, which faces the weapon housing, the detent 23 is accordingly in comparison to the first embodiment Figure 2a designed differently so that it extends almost the entire length of the inside.

In contrast to the first embodiment according to Figure 2a a continuous locking link 57 is provided on the loading lever holder 17 here. The latching link 57 extends from the rear end of the loading lever holder 17 in an approximately U-shaped manner around the outer contour of the end 50 facing the weapon housing 3. The latching link 57 serves to insert the loading lever 13 into a slide or loading lever housing 59 ', which is shown in FIG Figure 3b is shown.
The loading lever housing 59 'comprises a bearing 99 with a rail-shaped guide link 103 formed parallel to the continuous latching link 57. The loading lever 13' is therefore inserted with its latching link 57 into the guide link 103 and is placed there accordingly. For disassembly is here as well as for the pull the first embodiment of the dismantling slide 43 against the spring force of the dismantling sliding spring 45 from the loading lever holder 17 and to remove the loading lever holder 17 with its latching link 57 from the bearing 99 for the loading lever holder 17 to the rear. For assembly, it is sufficient to push the loading lever holder 17 with its latching link 57 into the bearing 99 for the loading lever holder 17 and into its guide link 103 as far as it will go. The spring-loaded locking pin 51 slides over its bevel 52 into and over the inner contour of the bearing 99 for the loading lever holder 17 and plunges into the complementary bore 87. In this position, the loading lever holder 17 is completely fixed and locked.

The in Figure 3a shown carriage or the loading lever housing 59 is for assembly with or disassembly of the loading lever 13 according to the first embodiment Figure 2a provided and formed as an aluminum extrusion. On the upper side 61 of the loading lever housing 59 there is an elevation 63, which is located partially above the bearings 83 formed on both sides. At its front end, ie towards the muzzle of a self-loading firearm, a padded stop 67 is provided. This is used to strike a fixed stop 109 (cf. Figure 4a , 5a , 6a and 9 ) and limits the movement of the loading lever housing or slide 59 to the front, beyond its rest position. At the rear end of the carriage 59, an approximately wave-shaped elevation 69 is formed. The area between the two ridges 63 and 69 is recessed at the top of the carriage 59 via a large-area recess 71 in order to save weight.

A front slide guide 73 and a rear slide guide 75 are provided on both sides of the outside of the slide 59. Both slide guides each comprise upper guide sections 77 and lower guide sections 79 which engage with guide rails 175 which are provided on the inside of the upper part of the weapon housing (cf. Fig. 21 , 22a and b ).

The front and rear slide guides 73 and 75 together form a type of two-point guide in order to keep the overall frictional resistance of the slide 49 against the guide rails 175 in the weapon housing 3 low.

The bearing 83 for the loading lever holder 17 extends approximately adjacent to the front carriage guide 73 in the longitudinal direction of the carriage 59. In the first exemplary embodiment shown here, locking lugs 85 are formed on the top and bottom of the outer contour of the bearing 83. As stated, the loading lever holder 17 with its complementary locking lugs 49 is placed between the locking lugs 85 in the bearing 83 from the outside and inserted and then moved under the locking lugs 85 in the bearing 83 to the rear until the locking lugs 49 are positioned behind the locking lugs 85 and themselves the locking pin 51 is located opposite the locking pin bore 87 in the carriage 59 and can dip into it.

A further through bore 89 is provided approximately in the center of the bearing 83, and a locking aid pin 125 can be inserted into it. This is particularly from the Figures 4c , 5c , 6c and the enlarged detail in Figure 8 refer to. Its mode of operation is explained in more detail in the context of these figures.

The upper side surfaces 91 of the carriage 59 extend adjacent to the bearing 83 with a slight bevel, the undersides of the carriage 59 are also partially recessed to save weight. In addition, further recesses 93 extend in the longitudinal direction of the slide 59 to further save weight. A receptacle 95 for the gas piston rod 111 penetrates the entire slide 59 in the longitudinal direction approximately in the center. The underside of the carriage 59 is designed or formed in the region of the front and rear carriage guides 73, 75 in an approximately semicircular manner, as is the section 98 which extends in the longitudinal direction and connects the two sections 73, 75. This serves for improved guidance of the carriage 59 and the gas piston rod 111.

Figure 3b shows the second embodiment of the carriage 59 'according to the assembly and disassembly of the loading lever (s) 13' Figure 2b is provided. The carriage 59 'also includes front and rear carriage guides 73 and 75 on both sides with upper and lower guide sections 77 and 79. The area 107 between the carriage guides 73 and 75 is more or less circumferentially recessed. For this reason, in comparison to the first embodiment, no further cutouts are provided which extend in the longitudinal direction inside the carriage 59 '.

A buffer bearing 104 is provided on the upper side of the slide 59 ′ in the vicinity of the front slide guide 73 and is fitted with a rubber buffer 106 (cf. Figure 4a , 5a , 6a and 9 ) can be engaged. The rubber buffer 106 can be fixed to the buffer bearing 104 via a cross pin (not shown) which can be inserted into the cross pin bearing 105. The buffer 106 serves as a stop with the fixed stop 109 on the inside of the weapon housing (cf. Figure 4a , 5a , 6a and 9 ) and, as in the first exemplary embodiment, limits movement of the through-loading device 1 beyond its rest position.

At the rear end of the carriage 59 ', bearings 99 for the loading lever holder 17 are made on both sides Figure 2b intended. These comprise an approximately U-shaped continuous guide link 103, each of which is provided for engagement with the circumferential locking link 57 which is approximately complementary thereto. The loading lever 13 'can thus be used either on the left and / or right side, that is also on both sides, and it can be pushed fully into the left or right side bearing 99 as far as it will go. The two bearings 99 each extend to the rear end 101 of the carriage 59 '. Provided approximately in the middle is an approximately square-shaped receptacle 95 for the gas piston rod 111, which extends in the longitudinal direction of the carriage 59 'and passes through the carriage 59' from its rear end 101 to the front. The underside of the slide 59 'comprises a semicircular outer contour 97 which extends over its entire length and widens in the areas of the front and rear slide guides 73, 75 over the cross section of the slide 59'.

Figures 4a , 5a and 6a each show a side view of the carriage 59 '(second embodiment) Figure 3b with through-loading lever 13 'mounted thereon and a partial cutout of the closure carrier (cf. Figures 4a , 5a and 6a ). The slide 59 'is penetrated by a gas piston rod 111 of the self-loading firearm. Figures 4b , 5b and 6b each show a cross-sectional view along the sectional plane II and Figures 4c , 5c and 6c each a longitudinal sectional view along the sectional plane II-II.

In the Figures 4a to 4c is the loading lever 13 'via the loading lever holder 17 in the associated bearing 99 of the carriage 59', the locking pin 51 of the Disassembly slide 43 is in engagement with the associated bore 87. In Figure 4a the loading lever handle 15 is locked and fixed via its loading lever latching or latching lug 23 on the weapon housing (not shown) at the counter latch 24 provided there. When the lock carrier 119 moves, the loading lever 13 does not run with it. At the top of the carriage 59 ', the rubber buffer 106 is fixed to the buffer bearing 104 via a cross pin (not shown) in the cross pin bearing 105. The rubber buffer 106 abuts the fixed stop 109 of the weapon housing (not shown here) and limits a forward movement of the through-loading device 1. At the front lower end of the breech carrier 119 there is a breech carrier guide 120 for guiding on a guide rail 175 (cf. Fig. 21 , 22a , b ) provided on the inside of the gun housing 3. The closure carrier guide 120 is also formed on both sides of the closure carrier 119.

The carriage 59 'is pushed over the front end 115 of the gas piston rod 111 and penetrated by it in a longitudinally movable manner. The rear end 113 of the gas piston rod 111 (cf. Figure 8 such as Figures 4c , 5c and 6c ) is inserted approximately centrally in a complementary recess 117 in the front end of the closure carrier 119, fixed in a known manner via a thread (not shown) and secured via a cross pin 117. The loading lever holder 17 rests with its rear contact surface 121 on the front of the closure carrier 119.

In Figures 5a, 5b and 5c the loading lever handle 15 is folded away from the carriage 59 'rearward into its actuating position. To this end, the loading lever handle 15 can be pivoted about the loading lever axis 31 against the force of the spring 35 and is guided in the rear end of the elongated hole 33. The locking pin 51 of the disassembly slide 43 is in engagement with the associated bore 87 in the carriage 59 '.

In addition, in Figures 4b and 4c as well as the parallel Figures 5b, 5c and 6b, 6c the auxiliary locking pin 125 is shown, which is movably guided within a bore 55 within the loading lever holder 17 transversely to the longitudinal direction of the self-loading firearm and is arranged parallel to the locking pin. The locking aid pin 125 comprises an inner end 129 which faces the gas piston rod 111 and can be brought into engagement with a recess 127 in the gas piston rod 111. The locking aid pin 125 is from a spring 137, which is supported on the one hand on a projection on the locking aid pin 125 and is supported on its side facing the slide 59 'on a locking aid spring bearing 138 in such a way that it prestresses the locking aid pin 125 in the direction of the loading lever axis 31.

In the in Figures 4a to 4c shown rest position of the loading lever 13 is a wedge-shaped end portion 131 of the locking pin 125 in engagement with a locking latch 34 provided at the inner end 20 of the loading lever handle 15 above the elongated hole 33, which has approximately the shape of a rounded trapezoid. This locking latch 34 thus holds the loading lever handle 15 additionally in its locked rest position.

When pivoting the loading lever handle 15 from its in Figures 4a to 4c rest position shown in its in Figures 5a to 5c shown operating position, the loading lever latch 23 is out of engagement with the counter-latch 24 on the weapon housing 3 and the loading lever handle 15 is folded down in approximately 80 to 85 degrees to the gas piston rod 111. As in Figures 4b , 5b and 6c shown, the bearing axis 31 is surrounded by a spring 35 which additionally biases the loading lever handle 15 into its rest position. Transfer to the actuation position (cf. Figures 5a to 5c ) takes place as against the spring force of the spring 35.

When pivoting the loading lever handle 15, the inner end 20 of the loading lever handle 15 rotates about the position axis 31. The wedge-shaped end 131 of the locking aid pin 125 moves relative to the locking catch 34 such that when the wedge surface 131 is acted upon by the rounded inner end 20 of the loading lever handle 15 Locking aid pin 125 is shifted within the loading lever holder 17 in the direction of the gas piston rod 111. How out Figures 5b and 5c As can be seen, the locking aid pin 125 protrudes from its bore 55 in the loading lever holder 17 in the direction of the gas piston rod 111, but is not yet in engagement with one of the recesses 127 formed on both sides in the gas piston rod 111.

In Figures 6a to 6c the loading lever handle 15 is in its closing aid position. In this position, the loading lever handle 15 is pivoted about 90 degrees to the rear and is also pushed manually into the loading lever holder 17. Here is the locking aid pin 125 inserted from the inner end 20 of the loading lever handle 15 against the force of the closing aid pin spring 137 such that the closing aid pin 125 engages with one of the two recesses 127 in the gas piston rod 111 with its end facing the gas piston rod 111.

In this fixed locking aid position, the loading lever handle 15 and thus the loading device 1 can now be moved forward in the direction of the muzzle of the weapon, the entire loading lever 13 being fixed to the gas piston rod 111 due to the locking aid pin 125 being fixed in the recess 127. Since the gas piston rod 111 in turn, as previously described, engages with the closure carrier 119, the gas piston rod 111, the loading lever 13 and the closure carrier 119 can be moved forward, for example in order to move the closure carrier 119 from its incompletely closed position into its closed position Position (cf. Figures 16a to 17b ) to the front, the breech head 172) completely feeding a cartridge into the cartridge chamber 155 and locking it there. In the locking aid position, for example, a cartridge can also be fed manually and therefore with little noise. The latched through-loading lever 13 can also be used as a closing aid for this.

Figure 6a shows the position in which the closure head 172 is locked in the cartridge chamber 155. The rubber buffer 106 bears against the fixed stop 109 in the weapon housing 3 and the loading lever holder 17 bears against the front of the breech bracket 119 with a stop surface 121.

When loading, the loading lever 13/13 'can be moved backwards both in its actuation position and in its closing aid position. In practice, the locking aid pin 125 is not locked for loading. In the event of a lock, however, when the breech carrier and slide 59 'are advanced, the loading lever handle 15 of the loading lever 13/13' is automatically pivoted into its starting position, so that a part does not inadvertently protrude or protrude from the weapon and could possibly endanger the shooter when shooting .

The loading lever handle 15 and the locking aid pin 125 automatically disengage from the locking aid position when the loading lever handle 15 is out of its rearmost position (cf. Figures 18 and 18a to 19b ) is released and the closing spring 161 drives the closure carrier 119 and thus the slide 59 'and the loading lever 13 to the front and the loading device 1 hits the housing. The actuation position is also referred to as the loading position.

Figure 7 shows an enlarged detail view of the loading lever handle 15 and the loading lever holder 17 and the loading lever 13 'in the closing aid position. The dismantling slide 43 is fully inserted into the loading lever holder 17 and the locking pin 51 is thus fixed. When the loading lever handle 15 is pushed in, the locking aid pin 125 is displaced in accordance with the length of the elongated hole 33 up to the stop on the loading lever axis 31 at the second end of the elongated hole 33.

Figure 8 shows a longitudinal sectional view through the view Figure 7 . The through-loading lever 13 'is in its closing aid position, in which the end of the closing aid pin 125 engages with the recess 127 in the gas piston rod 111. Here is the slot 33 with its end facing the loading lever handle 15 in abutment with the loading lever axis 31. The wedge surface 133 at the opposite end of the locking aid pin 125 is out of engagement with the latching recess 34 at the inner end 20 of the loading lever handle 15. In addition, a stop and Locking pin 141 shown, which limits the movement of the locking aid pin 125 within the loading lever holder 17 and which prevents the locking aid pin 125 from rotating. The inner end 20 of the loading lever handle 15 comprises a locking surface 139, via which the inner end 20 of the loading lever handle 15 is supported on the inner housing of the loading lever 13/13 'when the loading lever handle 15 is in the closing aid position. In order to counteract any wear due to the leverage effect, the locking surface 139 is sufficiently large. The locking surface 139 prevents the loading lever handle 15 from folding forward. Figure 9 shows an enlarged detail view of the front of the carriage 59 ' Figures 4a to 6c with its front slide guide 73. The rubber buffer 106 is mounted in the buffer bearing 104 via the cross pin (not shown) which can be inserted in the cross pin bearing 105. In the rest position of the through-loading device 1, the buffer 106 comes into contact with the fixed stop 109 which is inserted in the inside of the weapon housing 3. Of the Fixed stop 109 limits a forward movement of the carriage 59 'towards the mouth beyond the rest position.

Figure 10 shows a perspective view of the carriage 59 'with the loading lever 13' inserted therein. The loading lever handle 15 is in its folded position, in which it is locked on the weapon housing (not shown) with its loading lever latch 23. The loading lever 13 'is inserted into the bearing 99 of the slide 59' and the locking pin 51, as explained above, is locked, so that the dismantling slide 43 is completely in the loading lever holder 17. The loading lever 13 is in its rest position.

Figure 11 shows a perspective view of the carriage 59 'with the loading lever 13' removed. The dismantling slide 43 is in its locked position, in which it is pushed in and rests on the loading lever holder 17. For disassembly via the disassembly slide 43, as already described, the locking pin 51 was pulled out within the bore 53 against the spring force of the locking pin spring or disassembly slide spring 45 (cf. Figures 12 and 13 ), so that it came out of engagement with the locking pin bore 87 in the bearing 99 with its side facing the gas piston rod 111 and was approximately flush with the end 50 of the loading lever holder 17. In the in Fig. 11 In the position shown, the circumferential locking link 57 can be inserted into the guide link 103, which is complementary thereto, optionally on the left or right side in the carriage 59 '. When the loading lever holder 17 is fully inserted, the locking pin 51 engages in the bearing 99 by the force of the dismantling slide spring 45, more precisely in the complementary bore 87 provided there.

In the loading lever housing 59 of the first embodiment, the locking pin 51 is automatically pressed against the force of the spring 137 when the loading lever housing 59 is pressed into the bearing 83 and also automatically locks in the bore 87 when the loading lever housing 59 strikes in the rear part of the bearing 83. The disassembly slide 43 only has to be actuated if the loading lever housing 59 is to be removed.

In the case of the loading lever housing 59 'of the second embodiment, the locking pin 51 has a bevel 52 at its latching end (cf. Fig. 8 ). To slide into the bearing 99 for the loading lever holder 17, the dismantling slide 43 does not have to be pulled out.

It is sufficient to simply push the loading lever housing into the bearing 99, the locking pin 51 being acted upon by the slope 52 against the force of the dismantling slide spring 45 and automatically engaging in the bore 87 as soon as the loading lever housing 59 'strikes the front part of the bearing 99. The dismantling slide 43 only has to be actuated to remove the loading lever housing 59 '.

Figures 12a to 12c show the through-loading lever 13 'fully inserted into the left-hand bearing 99, which is in the stop 99 in the stop, but is not yet locked there. The dismantling slide 43 still protrudes from the loading lever holder 17. The locking pin 51 comprises a bevel 52 at its front end, which faces the bearing 99 (cf. also Figure 8 ). When the loading lever holder 17 is inserted into the bearing 99, this oblique surface 52 overflows the contour of the rear guide link 103. When the loading lever holder 17 is inserted, the bevel 52 and thus the locking pin 51 are displaced in the direction of the locking pin spring and thus acted upon and compressed. Only when the locking pin 51 is in alignment over the bore 87 in the bearing 99 in its rolling position, does the locking pin 51 penetrate into the bore 87 and latches the loading lever 13.

Furthermore, in, in Figure 12b Section plane II shown, the receiving bearing 36 for the loading handle leg of the leg spring 35, which pivots the loading lever handle 15 into the folded starting or rest position. The leg spring 35 itself is not shown here. The cross-sectional representation in Figure 12c along the section plane II-II Fig. 12b shows the bearings 99 formed on both sides for receiving the loading lever 13 '. The cross pin 123 is also shown as a holding pin for the dismantling slide 43.

Figure 13 shows a further perspective view of the carriage 59 'without the gas piston rod 111 and with the loading lever 13' inserted or inserted but not locked. The loading lever holder 17 is fully inserted into the left bearing guide link 103 of the bearing 99. The dismantling slide 43 projects with its outer end out of the loading lever holder 17, so that the loading lever holder 17 is not locked in the bearing guide link 103. The right side of the warehouse 99 is free.

In the side view of the Figure 14a and the longitudinal section along the section planes II in Figure 14a and the cross-sectional representation in Figure 14c along the section planes II-II in Figure 14b the loading lever 13 'is shown in its fully inserted position in the bearing 99 and additionally locked there. The dismantling slide 43 is located completely in the loading lever holder 17, so that the locking pin 51, with its end facing the carriage 59 ', is immersed in the bore 87 in the carriage 59' and is locked there. The auxiliary locking pin 125 is disengaged and is located outside the bore 89. The auxiliary locking pin spring 107 is supported on its spring bearing 138 within the loading lever holder 17, more precisely within the bore 55, and urges the auxiliary locking pin 125 against the inner end 20 of the loading lever handle 15 the wedge surface 133 on the locking pin 125 within the locking catch 34 and thus locks the loading lever 13 in a force-locked manner in its folded rest position.

Figure 15 shows a comparable perspective representation for illustration Figure 13 , in which the disassembly slide 43 is in its locked position, in which the locking pin 51 is in engagement with the bore 87 within the bearing 99 on the slide 59 '.

Figures 16a, 16b and 18a and 18b show, as stated at the outset, parts of a self-loading firearm with a through-loading device 1 inserted therein. Figures 17a, 17b and Figures 19a and 19b show the representation Figures 16a, 16b and 18a, 18b without upper part 3.

The pipe 143 comprises a muzzle fire damper 145 at its front end. On the pipe top, a gas outlet 147 is fixed in a known manner and mounted on the pipe 143 via a pin or retaining pin 149. In the area of the gas takeoff 147, the gun barrel 143 is provided in a reinforced section 151. To the rear, the tube passes into a cartridge chamber 155, into which a cartridge (not shown) is inserted in a known manner via the closure head 172.

On the underside of the upper part 3 of the weapon housing, two receptacles 11 for the attachment of a handle piece (not shown) and a hand protection attachment are shown.

At the rear end of the weapon housing upper part 3 there is a further receptacle 153 for a rear locking pin for a handle and base piece, not shown. The well-known Picatinny rail 5 is located on the upper side of the upper part 3 of the weapon housing. The upper part of the upper part of the weapon housing 3 is provided by guide slots 7 formed on both sides for an optional left-hand or right-hand installation of the loading lever 13 with its loading lever handle 15 and loading lever holder 17. The loading lever handle 15 is with its loading lever latching in the Figures 16a to 17b fixed to a counter detent 24 on the weapon housing in its rest position.

In the rest position, the through-loading device 1 (and thus the through-loading lever 13) is in its foremost position, in which the buffer 106 rests on the slide 59 'on the fixed stop 109 in the inside of the upper part 3 of the weapon housing.

In Figures 17a and 17b (without upper part of the weapon housing 3) is shown how the breech member 119 with its upper front end on the loading lever holder 17, more precisely on its contact surface 121 (cf. Figure 2b and 4c to 6c ) is present. The underside of the breech carrier 119 lies against the cartridge chamber 155, the breechhead 172 being arranged in the locked position within the cartridge chamber 155. A control pin 157 is provided within a control link 158.

A firing pin safety device 159 is provided at the rear lower end of the lock carrier 119. The upper rear end of the closure carrier 119 adjoins a closing spring 161 which surrounds a closing spring guide tube 163.

When the shot is fired, the breech block 119 is acted upon by the propellant gases branched off via the gas take-off 147, which act on the front end 115 of the gas piston rod 111, and is decoupled from the loading lever 13 and the slide 59, 59 '. Since the carriage 59, 59 'is fixed in its starting position on the weapon housing 3, it does not run with it. In the rearmost position of the closure carrier 119 (cf. Figures 18a to 19b ), the closing spring 161 is completely compressed and the closure bracket 119 receives the closing spring guide tube 163, so that the closing spring 161 now urges the closure bracket 119 forward.

At the rear end of the lock spring guide tube 163 and the lock spring 161, a base piece 165 is provided in a known manner, at the upper end of which a locking pin 167 is provided for coupling to the upper side 3 of the weapon housing. A known removal handle 169 and a receptacle 171 for receiving a housing holding pin are provided on the underside of the base piece 165.

Going back to Figure 16a is the through-loading lever 13 'compared to the first embodiment offset by about 6 cm in the weapon housing to the rear. This is due to the different arrangement of the bearings 99 and 83 (cf. Figures 3a and 3b ) on slide 59 or 59 '. Correspondingly, the counter-catch 24 on the upper part 3 of the weapon housing is also offset in the two embodiments.

Through-loading simulates firing a shot, but is carried out manually. For this purpose, as mentioned at the beginning, the loading lever handle 15 is pivoted backwards by approximately 90 degrees (cf. Figures 18a to 19b ). The shooter now grips the loading lever handle 15, depending on whether it is attached to the left or right weapon side, on the left or on the right weapon side, this being released from the counter detent 24 by the weapon housing 3.

When the loading lever handle 15 is guided to the rear, in the first embodiment the back of the slide 59 and in the case of the second embodiment the contact surface 121 acts on the front of the locking carrier 119. The locking carrier 119 can be manually operated together with the loading lever handle 15 and the loading lever holder 17 as well as the Guide the slide 59 'backwards within the guide slot 7 against the force of the closing spring 161. In the process, the breechhead 172 overflows a magazine (not shown) inserted into the self-loading firearm.

Figures 18a to 19b show the closure carrier 119 and the slide 59 'in their rearmost position, in the in Figure 19a the closure head 172 is also shown. The control pin 157 is located within the link 158 in its foremost position, in which the breechhead 172 can be unlocked from the cartridge chamber 155 and brought out. The locking or unlocking within the control link 158 takes place in a known manner. The closing spring guide tube 161 is completely within the Closure carrier 119 added. The front end 115 of the gas piston rod 111 is completely decoupled from the gas outlet 147.

Is now in the Figures 18 to 19b When the loading position or operating position of the loading levers 13, 13 'is released or possibly manually engaged for a quiet closing, the breech head 172 engages a cartridge in the magazine (not shown here) with a front lower end, and leads it out of the magazine into the Cartridge bearing 155, the locking head 172 being guided along the control link 158 in a known manner and thus locking within the chamber 155. The buffer 106 also stops with the fixed stop 109 inside the upper part of the weapon housing, the latching of the possibly locking locking pin 125 being released, so that the loading lever handle 15 swivels forward again into its initial or rest position and on the upper part 3 of the weapon housing in the counter-latch 24 formed there locked. The weapon is now fully loaded and ready to fire.

Figures 20a to 20c show further perspective representations of the carriage 59 and loading lever 13 of the first embodiment (cf. Figures 2a and 3a ). In Figure 20a the loading lever holder 17 is inserted into the bearing 83 of the carriage 59. The locking lugs 49 are aligned with the recesses between the locking lugs 85 in the bearing 83 of the slide 59. The locking lugs 85 on the bearing 83 together form a bearing link. In this position, the loading lever 13 can be inserted into the bearing 83 or removed there. The dismantling slide 43 is located in Figure 20a in its locked position, so it is fully inserted into the loading lever holder 17. The locking pin 51 (cf. Figure 2a ) looks out on the lower side of the loading lever holder 17.

In Figure 20b the disassembly slide 43 is pushed out of the loading lever holder 17, so that the locking pin 51 is inserted into the underside of the loading lever holder 17. In this position, the underside of the loading lever holder 17 lies completely on the surface of the bearing 83.

Locking the loading lever holder 17 is in Figure 20c shown. Compared to Figure 20b is the loading lever holder 17 moved back so that it is there with the stop of the outer end of the bearing link. The locking pin is in this position (see. Figure 2a ) above the associated complementary bore 87 within the bearing 82 of the carriage 59 and can be immersed there, the dismantling slide 43 again being flush with the outside 37 of the loading lever holder 17. When the loading lever holder 17 is moved rearward within the slide 59, the locking lugs 49 are moved relative to the bearing link and the locking lugs 85 and are placed behind by the latter. The loading lever 13 is thus locked and fixed in the bearing 82.

Fig. 21 shows a side view of the weapon housing of the assault rifle HK433 from the applicant of the same name from a parallel application DE 10 2017 002 242.9 . Fig. 22a and 22b each show cross-sectional views through the weapon housing Fig. 21 along the section planes AA and EE. The details of this gun case are in the DE 10 2017 002 242.9 described.

The breech guide rails 175 are formed approximately in the center on both sides in the weapon housing 3 and extend for engagement with bilateral guide grooves of the breech carrier guide 120 on the upper side of the breech carrier 119 and with the front and rear slide guides 73 and 75 approximately at right angles to the inside. The lock guide rails 175 are formed in one piece with the monolithic weapon housing during extrusion or during extrusion of the weapon housing 3 over approximately the entire length of the weapon housing. The lock guide rails 175 form a rail guide both for the lock carrier 119 and for the slide or the loading lever housing 59, 59 '.

Due to this housing guide, the loading lever can be arranged relatively far back in the weapon, which in turn improves the ergonomic handling of the loading device 1.

Further refinements of the invention result for the person skilled in the art within the scope of the following claims and attached drawings.
