Description

Field of invention

The present invention relates to a weapon housing for a self-loading firearm according to claim 1.

The invention also relates to a self-loading firearm equipped with such a weapon housing.

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

A weapon housing is the component that houses the barrel, the trigger mechanism, the breech assembly and the loading device.

A loading device is used to load a self-loading firearm using a loading lever in order to put it in 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 locking arrangement is provided in the weapon housing for firing a shot, extracting a fired cartridge case and reloading it. To fire the shot, the breech assembly, in particular its breech head, introduces the top cartridge from the magazine in a known manner into a cartridge chamber in the barrel. When a trigger mechanism is activated, a firing pin hits the base of the cartridge and ignites a propellant charge there, so that a Projectile is fired from the cartridge case through the tube. As soon as the projectile passes the hole in the weapon barrel, the propellant gases released during the firing process can be diverted into a gas outlet with a gas pressure charger. The branched off propellant gases are used to cause the closure arrangement to move backwards in a known manner. The propellant gases drive the closure assembly backwards towards the shaft at high speed via the gas pickup and a gas linkage coupled to it. In the case of a recoil loader, the drive takes place via the bullet impulse and the gases driving the bullet, which in this case act directly on the bolt head via the cartridge case and drive 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 assembly moves back. An ejection device then pushes the cartridge case out of the weapon housing via a cartridge ejection window in a known manner. When the shutter assembly returns, it slides over the magazine towards the stock. During the subsequent advance of the breech assembly, the breech head in particular now grabs the top cartridge from the magazine and feeds it into the cartridge chamber and the cycle repeats itself. 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 over a certain distance at their upper end. 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 upwards within the magazine housing and this thus pushes the cartridges upwards to the magazine lips.

In so-called self-loading firearms, the breech (bolt carrier and breech head) is in its forward position before the shot is fired as shown above, ie the breech head is located on the cartridge chamber. After inserting a first or possibly a new magazine into the self-loading firearm, the above-mentioned loading is now carried out.

With a so-called closing bolt, the bolt is brought into a rear position using the loading lever before firing (before the trigger is curved), in which it is caught by the trigger mechanism.

Known loading devices are often attached directly to the breech, with the loading lever allowing the breech to be moved backwards, i.e. towards the stock, so that the breech is moved backwards via the magazine against the force of the recoil spring. When the bolt then advances, the bolt head takes the top cartridge from a magazine and inserts it forward into the chamber, with the loading lever attached to the bolt following all movements of the bolt.

A charging lever that is firmly coupled to the closure is provided, for example, in the applicant's well-known G36 or also in the well-known SA 80. Such a charging lever is also referred to as a rotating charging lever because, due to the coupling with the bolt carrier, it also follows the previously described forward and backward movement. If the loading lever protrudes from the weapon, there is a risk of injury to a shooter. If the protruding charging lever hits an obstacle, this can lead to loading jams. Such a fixed mounting on the breech is now known in both military and civilian self-loading rifles.

Non-rotating charging levers are also known from the AR15 variants such as the HK 416/417 from the same applicant. In addition, it is known that the loading lever can be mounted and dismantled on the loading device without tools.

Even before the First World War, loading devices were developed in which the loading lever was decoupled from the breech after loading. Due to this decoupling, the disadvantage is that the shutter cannot be closed using the charging lever in the event that it does not close properly.

Overall, loading devices are known in a wide variety of designs; these can also have a loading lever that is provided either on the right or left side of the weapon.

For example, from the DE 101 22 345 C1 The same applicant has known a non-rotating cocking slide that is mounted on one side and can be operated on one side, in particular for the MG4, by means of which the closure is pretensioned against the pressure of a closing spring. A longitudinal slot is formed in the housing with a clamping rail in which the tension 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 right side. Actuating one handle automatically releases the second handle from locking the weapon in order to carry out a loading process.

Furthermore, from the EP 0 489 024 B1 The same applicant has disclosed a loading device for self-loading handguns, in particular for the well-known G36, with a pivotable and lockable loading lever. 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.

With military weapons, the boundary conditions that occur during use are increasingly changing, such as ambient temperature, weapon temperature, contamination, continuous fire and the like. This can result in a cartridge not being fully fed in when it is inserted into the chamber or in some other way causing jamming. However, in the event of jamming, the locking system can often no longer be closed properly without additional manipulation, which puts the shooter at risk. Such loading jams are extremely rare, but in principle a military weapon should be as free of malfunctions as possible. In such cases, the closure can often be operated manually using an appropriate through-loading device, thereby eliminating any jamming.

From the US 7,798,045 B 1, a through-loading device with a non-rotating through-loading lever is known, the through-loading lever being provided with handles protruding on the left and right sides. This cannot be dismantled without tools and can also be operated either on the left or right side. The through-loading device comprises a carriage which has a catch hook at its end facing the bolt carrier, which engages in a corresponding recess on the bolt carrier in order to guide it forward towards the cartridge chamber in the function of a closing aid.

From the US Patents 9,109,848 B2 , US 8,156,854 B2 and US 8,561,517 B2 There are known through-loading devices that cannot be mounted on the left or right side without tools. The self-loading firearm disclosed there comprises a weapon housing and a handguard coupled to it, with the loading device being guided in the handguard. The loading lever can be pivoted between a rest and actuation position, whereby in the actuation position it engages with a recess in the gas piston rod both when loading and in its function as a closing aid. The loading device therefore does not act directly on the bolt carrier. In an alternative embodiment, the through-loading device is provided with operating handles designed on both sides.

The US 8,307,747 B2 discloses a further non-rotating through-loading device with a through-loading carriage with a spring-loaded catch lug for engagement with the lock carrier. The loading lever protrudes rigidly from the side of the weapon. In its function as a closing aid, the catch lug engages in the bolt carrier and guides 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 non-rotating through-loading carriage, which is designed to be directly coupled to the locking carrier via a locking pin. The Through-loading device is arranged on the top of the weapon and includes a spring-loaded central cocking handle, which acts either purely spring-loaded via a threaded connection or a pivotable lever on a locking element and transfers it from a rest position to its operating position, in which the cocking slide can be coupled directly to the bolt carrier. This through-loading device cannot be converted to either right-hand or left-hand operation without tools.

Furthermore, they show DE 199 03 321 A1 and the parallel US 2002/0046642 A1 from the applicant of the same name a loading lever arrangement for a handgun. The charging lever can be converted without tools, is mounted directly into the breech and is therefore designed to move. The loading lever cannot be swiveled and therefore protrudes 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 via a slide on the end of a longitudinal guide rod of the breech. In its closing aid function, the loading lever also engages with the longitudinal guide rod via the slide.

The US 3,686,998 reveals a pivoting loading lever that does not move when loading. A slider acts directly on the closure. When used as a closing aid, the pivoting loading lever is positively locked into place via an elongated hole on its axis and a hook provided on it with a locking extension. Disassembly without tools is not intended.

The US 2016/0047611 A1 discloses a rifle with a receiver-a bolt handle is positionable in a manual position extending from a side of the rifle to permit manual firing of the rifle and in a semi-automatic position. The position of the bolt carrier can be changed between the manual and semi-automatic positions without removing the bolt carrier from the rifle.

Finally, the reveals DE 10 2018 001 984 A1 a through-loading device of a self-loading firearm with a longitudinally movable breech in a weapon housing. The charging device comprises a charging lever which has a charging lever handle coupled to a charging lever holder, and a charging lever housing which is guided in a longitudinally movable manner in the weapon housing. The charging lever handle is provided so that it can be pivoted from a rest position into an operating position and vice versa in the charging lever holder. Furthermore, the charging lever holder is in or on

Charging lever housing can be mounted and removed on the left and/or right side without tools.

Task and solution of the invention

Against this background, it is the object of the invention to provide an alternative, structurally simple and functionally reliable weapon housing for a self-loading firearm. In particular, it is the object of the invention to provide a weapon housing that enables simple and functionally reliable loading. It is also an object of the invention to provide a self-loading firearm with such a weapon housing.

This task is solved by the subjects of independent claims 1 and 22.

The invention is therefore based on a weapon housing with a first guide slot within which a charging lever can be moved for moving a charging tube that can be brought into contact with the breech or is in contact. The weapon housing is suitable for a self-loading firearm that has a breech that is guided in the weapon housing in a longitudinally movable manner. The weapon housing is characterized by a second guide link connected to the first guide link via a first recess in the weapon housing, within which the loading lever can be moved to move the loading tube, so that the loading lever can be operated either on the left or right side in order to load the self-loading firearm.

The self-loading firearm according to claim 22 is characterized in that it is equipped with such a weapon housing.

By providing a second guide link, which is connected to the first guide link via a first recess, the loading lever can advantageously be operated either on the left or right side. To do this, a user simply needs to move the loading lever from left to right or from right to left. Because the loading lever can be folded over without modification or additional tools, a loading device that can be operated either on the left or right side of the weapon can be provided using structurally simple means, which can be adapted to the ergonomics of the shooter and therefore in particular to a left-handed or right-handed person is. Usability from both sides is a criterion that is often required in government tenders today.

The invention is also characterized by the fact that changing the loading lever from the first to the second guide slot and vice versa is possible very quickly since, as already mentioned, it can be implemented without modification and without tools. A major advantage is that the weapon can be passed from a left-handed user to a right-handed user and vice versa if necessary, and the new user can quickly adapt a weapon that was not originally aimed at them to their needs. This time saving is particularly advantageous in an operation such as a battle.

In addition, the second guide slot and the first recess result in a weight reduction, so that a lighter weapon housing or a lighter self-loading firearm can be provided. Loading activities can also advantageously be carried out in the secured state of the self-loading firearm, with fall safety in particular being guaranteed.

The process of changing the loading lever from the first guide link to the second guide link and vice versa is referred to as reversing the loading lever. The loading lever can be flipped when the weapon is unloaded, partially loaded or fully loaded. The loading lever can be flipped either with the weapon secured or unsecured.

The first and second guide slots can in particular be designed as a slot running in the longitudinal direction of the weapon housing, a so-called longitudinal slot. The loading lever is arranged to be movable within the guide slots in the longitudinal direction between two end positions, namely between a front end position and a rear end position. The two guide slots are expediently arranged symmetrically to one another.

The first recess can in particular be an opening in the upper weapon housing, which connects the two guide slots with one another. The The first recess can, for example, connect the front area of the first and second guide links, in particular the area in which the loading lever assumes its front end position, to one another.

However, it is preferred if the first recess connects the rear area of the first and second guide links, in particular the area in which the charging lever assumes its rear end position. If the recess is arranged in this area, the flipping of the loading lever can advantageously be combined with the loading of the weapon, so that loading and flipping can take place in one go. The arrangement in the rear area also protects against unintentional tipping, as the user has to consciously move the loading lever against the force of the closing spring in order to tip it over.

In a preferred embodiment of the invention, the first and second guide slots each have a recess for locking the loading lever, so that the loading lever can be locked on the left or right side of the weapon housing. The respective recess is intended in particular to hold the loading lever in the rear position, for example to enable a view into the cartridge chamber.

It is particularly advantageous if the respective recess is provided in the same recess that connects the first guide link with the second guide link. This makes it possible to quickly flip the charging lever from the locked position of the charging lever.

In a structurally simple embodiment, the respective recess has an extension pointing in the direction of the mouth of the weapon housing, in particular a semicircular extension. The term semicircular extension also means a U-shaped and/or V-shaped extension or geometry. The choice of the geometry of the recess can also depend on the geometry of the charging lever.

It is preferred if the two recesses are separated from one another by a housing section of the weapon housing, the housing section projecting beyond the two recesses in the direction of the shaft of the weapon housing. Such a housing section can reduce the risk of the charging lever being accidentally tipped over.

The extent of the first recess between the housing section and the part of the weapon housing opposite this section must be larger than the part of the charging lever that is guided through the first recess. A ratio d of the extent d1 of the recess and the corresponding extent d2 of the charging lever 1 <d <2.0 is expedient, where d = d1/d2.

A ratio in the range 1.0 < d < 1.5 has proven to be a good compromise between preventing unintentional flipping and intentional flipping of the holding lever. A ratio of essentially 1.2 has proven to be particularly preferred in this context.

In a preferred embodiment of the invention, a securing device is provided with a securing element which can be moved from a first position to a second position and vice versa, the securing element in the first position preventing the loading lever from being transferred from the first guide link to the second guide link or vice versa , and in the second position allows this transfer, and the securing device is designed to hold the securing element at least in the first position.

The safety device can be provided to prevent the loading lever from being accidentally flipped over. Unlike the ratio d described above, the safety device defines a mechanical lock or baffle that must be actuated by the user before flipping the charging lever.

The securing device is at least configured in such a way that a securing element is held in the first position, i.e. in the position in which tipping over is prevented. The security device is preferably additionally configured in such a way that that the securing element is also held in the second position, i.e. in the position in which flipping is permitted. However, it is conceivable that instead the securing element is held manually in the second position by the user using appropriate handling.

In a structurally simple embodiment, the securing element is arranged on the weapon housing or on a component connected to the weapon housing. In this context, it is particularly preferred that the securing element is arranged in or on a profile rail arranged on an upper side of the weapon housing. The Picatinny rail is an example of such a profile rail. The Picatinny rail is a NATO-standard, toothed rail for quick and repeatable mounting of accessories on firearms. It is particularly preferred to accommodate the securing device or the securing element on the front side of the profile rail or a component connected to the front side of the profile rail. This advantageously does not affect the assembly of accessories that generally initially extend vertically and then horizontally.

The securing element can in particular be designed as a securing pin, which in particular has a circular or polygonal cross section.

In a structurally simple embodiment, the securing element is arranged to be longitudinally movable and spring-mounted, and can be moved from the first position to the second position by pressing against the force of the spring and from the second position to the first position with the force of the spring. The longitudinally movable arrangement on the front side of the profile rail has proven to be particularly advantageous. The longitudinally movable arrangement enables easy handling for both left- and right-handed people. Alternatively, the securing element can be mounted in an articulated manner and can be pivoted about an axis from the first position to the second position and vice versa.

In the presence of the longitudinally movable and spring-loaded arrangement, it is preferred if the securing means comprises a gear that interacts with the spring in such a way that the securing element is in the first position and in the second Position can be maintained without the influence of an external force. Such a mechanism or mechanics is, in principle, similar to that of retractable ballpoint pens.

For example, by actuating the securing element against the spring force in the longitudinal direction, the loading lever can be pressed in until it audibly and/or tactilely engages in the second position. By pressing the securing element again or by activating an unlocking mechanism, it is unlocked from the second position and transferred to the first position using the spring force.

In a preferred embodiment of the invention, the weapon housing has at least one counter-latch for engaging a latching element of the loading lever, such that the loading lever can be secured to the weapon housing both in the first guide link and in the second guide link during a locking movement. The locking element and the charging lever are preferably designed in one piece, i.e. in one piece, with the locking element being designed in particular as a locking lug. For example, a further recess, a groove or the like can be used as a counter catch.

If the loading lever is fixed to the weapon housing, the loading tube, which is mechanically coupled to the loading lever, is also fixed to the weapon housing. Fixing the loading tube ensures that it does not move back and forth in the weapon housing when the weapon is in use and, in particular, does not negatively influence the closing function of the breech.

It is preferred if the at least one counter-catch is formed by a second and third recess in the weapon housing. This makes it possible to realize a structurally simple design. The second and third recesses can in particular be arranged axially between the mouth and the respective guide link. It is particularly preferred if the first guide link and the second recess as well as the second guide link and third recess are arranged essentially aligned with one another in the axial direction.

By essentially aligned is meant that, for example, the upper end of the respective guide link and the upper end of the second or third recess are aligned with one another, i.e., form a straight line in the longitudinal direction. In this context, alignment can also mean that, for example, only the lower end of the respective guide link and the lower end of the second or third recess are aligned with one another, i.e., forming a straight line in the longitudinal direction. It is preferred if both the respective upper and the respective lower ends of the guide slots or the second and third recesses each form a straight line in the longitudinal direction.

A second and third recess, which is arranged as an extension towards the front, is particularly easy to implement in terms of manufacturing technology. In addition, a loading lever with a substantially constant profile thickness can be used, which also enables a structurally simple loading lever.

A particularly secure engagement of the latching element, in particular the latching lug, is achieved in that the second and third recesses are polygonal, in particular rectangular. With such a second and third recess, it is expedient for the locking element, in particular the locking lug, to have a polygonal geometry corresponding to the second and third recess.

As already stated above, the security device with security element described above is preferably arranged on the profile rail for the weapon housing. Accordingly, a modified Picatinny rail is provided for the weapon housing.

The profile rail preferably has the securing device with the securing element on its end face pointing towards the mouth, the securing element being able to be moved from a first position to a second position and vice versa, and the securing device being set up to hold the securing element at least in the first position . At least in the first position, the securing element extends in the longitudinal direction of the profile rail in order to prevent the loading lever from being accidentally flipped over.

Such a profile rail can be referred to as an “extended” Picatinny rail. The safety device is advantageously arranged at the front so as not to impair the installation of accessories on the profile rail.

The securing element can in particular be designed as a pin or pin, which preferably has a cylindrical, angular or oval cross section. The securing element can be arranged by means of or on an elastically deformable element. A spring is an example of an elastically deformable element.

In a first embodiment of the profile rail it is provided that the securing element is arranged to be longitudinally movable and spring-mounted, and can be moved from the first position to the second position by pressing against the force of the spring and from the second position to the first position with the force of the spring .

A profile rail is particularly preferred if the securing device comprises a mechanism such as a gear that interacts with the spring in such a way that the securing element can be held in the first position and in the second position without the influence of an external force. Such a mechanism is advantageous because the user has one hand free, for example to flip the loading lever while holding the self-loading weapon with the other hand. In the case of the embodiment in which the securing means is only held in the first position by the securing device, the user would have to hold the securing means in the second position manually, for example on a side recess in the front region of the profile rail which is attached to the securing element and guided through a side recess handle.

As an alternative to the longitudinally movable locking pin, it is preferred if the locking element is mounted in an articulated manner and can be pivoted about an axis from the first position into the second position and vice versa.

The structure and functionality of the weapon housing for a self-loading firearm, which has a longitudinally movable breech in the weapon housing, or the self-loading firearm with such a weapon housing, are explained below with reference to the figures. The figures show preferred embodiments of the invention.

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

Fig. 1 shows a section of a self-loading firearm 100, in which the weapon housing according to the invention is used. The self-loading firearm is, for example, the applicant's Universal Submachine Gun (UMP), a self-loading recoil loader with a ground closure. The detail shows the left side of the self-loading firearm 100 or the weapon housing 10. Fig. 1 also represents a first snapshot.

The weapon housing 10 of the self-loading firearm 100 has a first guide link 11 designed as a longitudinal slot and a second guide link 12 designed as a longitudinal slot opposite the first guide link 11, the second guide link 12 being covered by the weapon housing 10 in this view. The first guide link 11 and the second guide link 12 are connected to one another by a first recess 13. The first recess 13 is arranged in the rear area of the guide slots 11, 12.

The self-loading weapon 100 also has a loading lever 20 which is guided within the first guide link 11 and is mechanically coupled to a loading tube 21. The loading lever 20 is arranged to be longitudinally movable within the first guide link and has a handle 22 by means of which a user can move the loading lever 20. Fig. 1 shows the charging lever 20 in its front end position. The charging lever 20 can, starting from this position, move in the direction 98 can be moved backwards, whereby the charging tube 21 is brought into mechanical contact with the closure and the closure is moved backwards against the force of the closing spring. If the loading lever 20 is moved maximally in the direction 98, it is in its rear end position. The movement of the charging lever in direction 98 corresponds to the movement in the direction of the stock.

The first and second guide slots also each have a recess for locking the loading lever 20, so that the loading lever 20 can be locked on the left or right side of the weapon housing 10. If the loading lever 20 is rotated from its rear position about the axis of rotation of the loading tube 21, it can be held securely in a first recess.

Opposite the first recess 14, i.e. on the right side of the weapon housing, a second recess 15 is provided, which allows the loading lever 20 to be locked if it is guided in the second guide slot.

The recesses 14, 15 are provided in the recess 13, i.e. the recess that connects the first guide link 11 with the second guide link 12. In other words, the recesses 14, 15 are part of the first recess 13.

The recesses 14, 15 each have a semicircular extension pointing in the direction 99, i.e. in the longitudinal direction forward. The movement of the charging lever in direction 99 corresponds to the movement in the direction of muzzle 50.

The first and second recesses 14, 15 are therefore separated from one another by a housing section 16 in the upper part of the weapon housing 10. According to this embodiment, the housing section 16 projects beyond the two recesses 14, 15 in the direction 98, i.e. in the direction of the shaft.

The weapon housing 10 also has a profile rail 30 on its top, which is intended for the assembly of accessories. A safety device 40 with a safety element 41 is provided at the front end of the profile rail 30. The According to this embodiment, the safety device 40 is an integral part of the profile rail 30. In this respect, it is an “extended” Picatinny rail. The safety device 40 can also be provided as a separate component. It is therefore conceivable to provide the safety device 40 as a modular accessory that is mounted on the front end of a known Picatinny rail.

The securing element 41 is designed as a cylindrical pin which is arranged on the end face 42 of the securing device 40 or the profile rail 30. The securing element 41 can be moved from a first position to a second position and vice versa, with the securing element 41 in the first position preventing the transfer of the charging lever 20 from the first guide link into the second guide link 12 or vice versa, and allowing this transfer in the second position . The security device 40 is also designed to hold the security element 41 in the first position and in the second.

For this purpose, the securing element 41 is arranged to be longitudinally movable and spring-mounted (not shown). The securing device 40 further comprises a gear (not shown) which cooperates with the spring in such a way that the securing element 41 can be held in the first position and in the second position without the action of an external force.

Fig. 1 shows the securing element 41 in the first position. In this case it is not possible to move the loading lever 20 from the first guide link 11 into the second guide link 12.

If the loading lever 20 is to be folded over, a user actuates the securing element 41 in the direction 98 until it clicks into place. The securing element 41 is now in the second position. The loading lever can now be folded over. The securing means 41 can then be moved from the second position to the first position by pressing again in direction 98.

The weapon housing 10 also has at least one counter-latch for engaging a latching element of the loading lever. If the loading lever 20 is engaged with its locking element in the counter-lock, the loading tube 21 is fixed to the weapon housing 20 and does not move while the shutter is moving. According to this embodiment, the counter-latch is formed by a second recess 17 and a third recess 18 in the weapon housing 10. The second recess 17 is arranged in an extension of the first guide link 11 to the front and thus axially between the mouth 50 and the first guide link 11.

The second recess 17 has a rectangular shape extending in the longitudinal direction, with the upper limit of the second recess 17 and the upper limit of the first guide link forming a straight line. The third recess 18 is covered by the weapon housing. It is arranged symmetrically to the second recess 17 on the right side of the weapon housing 10.

In the position of the charging lever 20 shown, the locking element of the charging lever 20 is engaged in the third recess 18.

The loading lever 20 is pivotably mounted on a spring within the loading tube. To release or unlock the locking lug from the third recess, the handle is moved backwards. The loading lever 20 is arranged in the loading tube in such a way that a movement backwards initially causes a pivoting movement about a vertical axis, whereby the locking lug is removed from the third recess 18.

As already mentioned, shows Fig. 1 the charging lever in the front end position. Based on the following Figures 2 to 10 the transfer of the loading lever 20 from the first guide link 11 into the second guide link 12 is explained. The following Figures 2 to 10 represent successive snapshots.

Fig. 2 represents a second snapshot and shows the loading lever 20 or the handle 22 in the first guide link 11 in its rear end position. The closing spring of the closure is now compressed to the maximum. The user's hand holding the handle 22 is not shown.

Fig. 3 represents a third snapshot. The tensioned loading lever 20 is locked in the first recess 14 after a pivoting movement to the right and movement forward 99. The first recess 14 surrounds the charging lever 20 so that it cannot slide down out of the first recess 14. The user can let go of the handle.

Fig. 4 represents a fourth snapshot. The tensioned charging lever 20 is locked into the first recess 14 without any changes. However, the securing pin 41 of the securing device 40 has now been moved from the first position along the arrow direction 98 into the second position. To do this, the user has pressed the locking pin 41 with his hand until it clicks into place. The locking pin is held in the second position by the locking device. In the second position of the locking pin 41, the charging lever 20 can now be folded over.

Fig. 5 represents a fifth snapshot. The loading lever 20 or the handle 22 is led out of the first recess 14 in the direction 98 and is now folded to the right.

Fig. 6 shows a sixth snapshot, which shows the charging lever 20 or the handle 22 in the middle, i.e. between the housing section 16 and the securing element 41.

Fig. 7 shows a seventh snapshot. The loading lever 20 or the handle 22 is now partially folded to the right. In this snapshot, the handle 22 is still held by hand in the area of the second recess 15.

Fig. 8 shows an eighth snapshot. The loading lever 20 and the handle 22, which are covered by the weapon housing 10, are now in the rear end position in the second guide slot 12, analogous to the position of the loading lever 20 Fig. 2 .

Fig. 9 shows a ninth snapshot. The locking pin 41 was transferred from the second position back to the first position.

Fig. 10 shows a tenth snapshot. This view shows the weapon housing 10 or the self-loading firearm 100 from the right side. The loading lever is now in its front end position within the second guide slot 12. The locking lug of the charging lever 20 is snapped into the opposite second recess 17.

The loading lever 20 has now been moved from the first guide link 11 via the first recess 13 into the second guide link 12. The loading lever 20 is moved from right to left in a similar manner.

At this point it should be noted that the steps explained above can also be carried out in a different sequence. This is how the safety device is transferred from the first position to the second position ( Fig. 4 ) also possible at another time, for example at the time of the snapshot according to Fig. 1 . It is not necessary to place the charging lever in the recess 14. The folding can also be done without snapping into the respective recess 14 or 15. However, it is advisable to let the charging lever 20 snap into the respective recess 14 or 15 if the locking pin 41 has not yet been moved into the second position.

Fig. 11 shows the through-loading device in an exploded view. The through-loading device therefore comprises a substantially L-shaped through-loading lever 20, which has a profiled handle 22 on one of its leg ends and a locking element 23 designed as a locking lug on its other leg end. The locking lug is directed forward, i.e. in the direction of 99.

The charging lever 20 can be replaced by a (in Fig. 11 (covered) elongated hole can be inserted into the side of the through-loading pipe 21. A leg spring 24 is arranged in such a way that one leg rests on the through-loading tube 21 and the other leg rests in the through-loading lever 20. A pin 25, which is guided through the winding of the leg spring 24 and corresponding holes in the charging lever 20 and charging tube 21, fixes the charging lever 20 on or in the charging pipe 21. The pin 25 also forms the axis around which the charging lever 20 counteracts or with the force or moment of the leg spring 24 can be pivoted. The leg spring is inserted pre-tensioned so that it always exerts a moment on the locking lug 23 in the direction of the second or third recess 14, 15 opposite the handle 22. This always allows the charging lever 20 to engage securely in the front end position. Against the force of the leg spring 24, the locking lug 23 can be guided out of the corresponding recess 14, 15 by the user, for example to carry out a loading process or to flip the loading lever.

On the side opposite the covered elongated hole, the through-loading pipe has a further elongated hole 26 and an open elongated hole 27, which are separated by a web 28. Part of the charging lever 20 can be moved through the longitudinally extending elongated hole 26. In other words, the elongated hole 26 provides a pivoting radius for pivoting the charging lever 20. Through the elongated hole 27, the locking lug 23 can engage in the second or third recess 14 or 15. An area 29 of the charging lever 20 can come into contact with the web 28.

Fig. 12 shows charging lever 20 and charging tube 21 in an assembled state in a perspective view. Also visible are the handle 22, the pin 25, the elongated surfaces 26, 27 and the web 28.

Fig. 13 shows a top view of the weapon housing 10 as well as that in Fig. 11 and 12 Through-loading device described in more detail in a section. To the left of the weapon housing is the first guide link 11 and the second recess 17 is arranged in its extension. To the right of the weapon housing is the second guide link 12 and the third recess 18 is arranged in its extension. The loading lever 20 is guided in the first guide link 11 and is in its front end position. The locking lug 23 of the charging lever 20 is snapped into the third recess 18.

For this purpose, the locking lug 23 is pressed through the elongated hole 27 of the through-loading tube 21 by the spring torque of the leg spring, not shown. The locking lug 23 engages through the elongated hole 27 into the recess 18 and rests against a boundary of the recess 18. Thus, the loading lever 20 and thus the loading tube 21 are fixed to the weapon housing 10. The loading lever can be pivoted about the axis of the pin 25 and can be unlocked by pivoting the handle.

Fig. 14 shows the charging lever of the Fig. 13 in an unlocked state. For this purpose, the handle 22 was first pivoted in the direction of the arrow 97 about the axis of the pin 25 and then moved in the direction 98. It can be clearly seen in this view that the third recess 18 extends longer to the rear on the outside of the weapon than on the inside of the weapon. In other words, the third recess 18 has a trapezoidal cross section. This profile, which tapers from the outside inwards, ensures that the locking lug 23 engages securely and makes it difficult for the locking lug 23 to be unintentionally unlocked in the locked state. The second recess 17 has a corresponding geometry, ie also a trapezoidal cross section.

Fig. 15 shows the section of the Fig. 13 in a vertical section. Loading lever 20 and loading tube 21 are therefore in an unlocked state in the front end position. It can be clearly seen in this view that the securing element 41 completely covers the first recess 13 in the axial direction and at least partially covers the housing section 16 of the weapon housing 10. However, it is also conceivable to provide a securing element that only partially covers the recess 13. So, with the appropriate thickness of the loading lever 20, it is sufficient if the securing element 41 covers the recess 13 only half or only two thirds or in an area in between.

Fig. 16 to 19 show the weapon housing 10 or the self-loading firearm 100 in a complete view, where Fig. 16 and 18 a perspective from the left side or a perspective from the right side and Fig. 17 and 19 show a side view of the left and right sides of the self-loading firearm.

The loading lever 20 or the handle 22 is guided in the first guide slot and is in the locked state in the front end position. The extended Picatinny rail 30 includes the safety device 40 with a safety pin 41 located in the first position. In this position, it is not possible to fold the loading lever 20 or the handle 22. The second recess 17 is arranged in an extension of the first guide link 11. For this purpose, the locking pin 41 projects beyond the recess 13, which connects the first guide link 11 with the second Leadership backdrop 12 connects. The shaft 60 is arranged opposite the mouth 50. For the rest, please refer to the comments Fig. 1 referred.

Fig. 20 finally shows the self-loading firearm 100 or the weapon housing 10 Fig. 17 , but without charging lever. It can be clearly seen that the first guide link 11 and the second recess 17 are arranged axially symmetrically and also aligned with one another. The same applies to the second guide link 12 and the third recess 18.

Further refinements of the invention will become apparent to those skilled in the art within the scope of the following claims and the accompanying drawings.
