Description

Field of invention

[0001] The present invention relates to a weapon housing of a self-loading firearm according to the preamble of claim 1.

[0002] The invention also relates to a self-loading firearm equipped with such a weapon housing.

[0003] In these documents, location terms 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 forward away from the shooter.

[0004] A weapon receiver is the component that houses the barrel, trigger mechanism, breech assembly, and charging device.

[0005] A charging device is used to cock a self-loading firearm using a charging handle, bringing it into a ready-to-fire state. The operating sequence for firing and automatic reloading in a self-loading firearm can be simplified as follows: The receiver contains a longitudinally movable bolt assembly for firing, extracting a spent cartridge case, and reloading. To fire, the bolt assembly, particularly its bolt head, feeds the top cartridge from the magazine into a chamber in the barrel in a known manner. When a trigger mechanism is actuated, a firing pin strikes the cartridge case and ignites a propellant charge, thus firing a projectile from the cartridge case through the barrel.As soon as the projectile passes through the bore in the gun barrel, the propellant gases released during firing can be diverted into a gas port in a gas system. These diverted gases are used to propel the breechblock assembly backwards in a known manner. The propellant gases, via the gas port and a connected gas rod, drive the breechblock assembly backwards at high speed towards the stock.

[0006] In a recoil-operated firearm, the drive is provided by the projectile impulse and the gases propelling the projectile, which in this case act directly on the bolt head via the cartridge case and drive it.

[0007] The bolt head incorporates an extractor that grips the cartridge case at its base and, during the recoil of the bolt assembly, pulls it from the chamber. An ejector then pushes the cartridge case out of the receiver through an ejection port in a known manner. During the bolt assembly's recoil, the cartridge case slides over the magazine and rearward toward the stock. During the subsequent forward movement of the bolt assembly, the bolt head again picks up the top cartridge from the magazine and feeds it into the chamber, and the cycle repeats. Alternatively, a recoil-loading mechanism of a known design can be used for this cycle.

[0008] To feed a cartridge, the upper surface of both the magazine's rear and front walls is recessed along a certain distance at their top. The magazine's side walls extend upwards, forming magazine lips that prevent the cartridge from falling out. A spring inside the magazine pushes the follower upwards within the magazine housing, which in turn pushes the cartridge upwards towards the magazine lips.

[0009] In so-called self-loading firearms, the bolt (bolt carrier and bolt head) is in its forward position before firing, meaning the bolt head is at the chamber. After inserting the first or possibly a new magazine into the self-loading firearm, the previously described racking process is performed.

[0010] In a so-called closing bolt, the bolt is moved to a rear position by means of the charging handle before firing (before the trigger is pulled), where it is caught by the trigger mechanism.

[0011] Common charging mechanisms are often attached directly to the bolt, with the charging handle allowing the bolt to be moved rearward, towards the stock, so that the bolt is forced backward over the magazine against the force of the recoil spring. During the subsequent forward movement of the bolt, the bolt head picks up the top cartridge from a magazine and feeds it forward into the chamber, with the charging handle attached to the bolt following all movements of the bolt.

[0012] A charging handle permanently coupled to the bolt is, for example, provided in the applicant's known G36 or the known SA 80. Such a charging handle is also referred to as a moving charging handle, since, due to its coupling with the bolt carrier, it also follows its previously described forward and backward movement. If the charging handle protrudes from the weapon, there is a risk of injury to the shooter. If the protruding charging handle strikes an obstacle, this can lead to malfunctions. Such a fixed mounting on the bolt is known today in both military and civilian self-loading rifles.

[0013] Furthermore, non-rotating charging handles are also known from AR15 variants such as the HK 416 / 417 of the same applicant. Additionally, it is known that the charging handle can be mounted and dismounted on the charging device without tools.

[0014] Even before the First World War, charging mechanisms were developed in which the charging handle disengages from the bolt after the action has been loaded. A disadvantage of this decoupling is that, if the bolt fails to close properly, it cannot be closed using the charging handle.

[0015] Overall, loading devices are known in a wide variety of designs; these can also have a loading lever that is located either on the right or left side of the weapon.

[0016] For example, from DE 101 22 345 C1 of the same applicant, a non-moving tensioning slide, mounted on one side and operable on one side, is known, particularly for the MG4, by means of which the breech is pre-tensioned against the pressure of a closing spring. A longitudinal slot is formed in the housing with a clamping rail in which the tensioning slide is guided and can be fixed.

[0017] From DE 10 2006 006 034 B3 of the same applicant, a charging device, e.g. for the HK416, is also known, in which the charging handle can be operated from either side via two handles, either on the left or right side. Actuation of one handle automatically releases the second handle from a locking position of the weapon in order to perform a charging operation.

[0018] Furthermore, EP 0 489 024 B1 of the same applicant discloses a charging device for self-loading handguns, in particular for the known G36, with a pivotable and lockable charging lever. This lever is arranged directly or via an intermediate piece on the bolt and can be pivoted out of the receiver on both sides of the bolt's longitudinal axis.

[0019] With military weapons, the conditions encountered during use are constantly changing, such as ambient temperature, weapon temperature, fouling, sustained fire, and similar factors. This can result in a cartridge not being fully fed into the chamber or a malfunction occurring in some other way. In the event of a malfunction, the bolt often cannot be properly closed without additional manipulation, endangering the shooter. While such malfunctions are extremely rare, a military weapon should ideally be as free of malfunctions as possible. Using a suitable charging handle, the bolt can often be manually operated in such cases, thereby clearing any malfunction.

[0020] US Patent 7,798,045 B1 discloses a charging device with a non-moving charging handle, wherein the charging handle is provided with handles projecting on the left and right sides. It cannot be disassembled without tools and can be operated from either the left or right side. The charging device comprises a slide which has a catch at its end facing the bolt carrier that engages in a corresponding recess on the bolt carrier to guide it forward toward the chamber, acting as a closing aid.

[0021] US patents 9,109,848 B2, 8,156,854 B2, and 8,561,517 B2 disclose charging devices that cannot be mounted on the left or right side without tools. The self-loading firearm disclosed therein comprises a receiver and a handguard attached to it, with the charging device guided within the handguard. The charging lever is pivotable between a rest position and an operating position, engaging a recess in the gas piston rod in the operating position both during charging and when acting as a closing aid. The charging device thus does not act directly on the bolt carrier. In an alternative embodiment, the charging device is provided with operating handles on both sides.

[0022] US Patent 8,307,747 B2 discloses another non-moving charging device with a charging slide featuring a spring-loaded catch for engagement with the bolt carrier. The charging handle is rigidly mounted laterally to the weapon. In its function as a closing aid, the catch engages the bolt carrier and guides it forward. US Patent 8,539,871 B1 shows a similar charging device.

[0023] German Patent FR 1,349,766 and the parallel German patent DE 1 208 221 disclose a charging device with a non-moving charging slide that can be directly coupled to the bolt carrier via a locking pin. The charging device is located on the top of the weapon and comprises a spring-loaded central cocking handle that acts either spring-loaded via a threaded connection or a pivotable lever on a locking element, moving it from a rest position to its operating position in which the cocking slide can be directly coupled to the bolt carrier. This charging device cannot be converted without tools for optional right- or left-handed operation.

[0024] Furthermore, DE 199 03 321 A1 and the parallel US 2002 / 0046642 A1 of the applicant of the same name disclose a charging handle arrangement for a handgun. The charging handle can be changed without tools, is mounted directly into the bolt, and is therefore designed to move with the bolt. The charging handle is not pivotable and therefore protrudes laterally from the weapon.

[0025] EP 0 207 058 B1 discloses a non-moving through-loading device with a non-removable, laterally pivotable, one-sided loading lever. During loading, the loading lever acts via a slide on the end of a longitudinal guide rod of the breech. In its closing-assist function, the loading lever also engages with the longitudinal guide rod via the slide.

[0026] US Patent 3,686,998 discloses a pivoting charging handle that does not move during cocking. A slide acts directly on the bolt. When used as a cocking aid, the pivoting charging handle is positively locked to a bolt extension via a slotted hole on its axis and a hook provided thereon. Tool-free disassembly is not provided for.

[0027] Finally, DE 10 2018 001 984 A1 discloses a charging device for a self-loading firearm with a bolt guided longitudinally within a receiver. The charging device comprises a charging lever, which has a charging handle coupled to a charging handle bracket, and a charging handle housing that is guided longitudinally within the receiver. The charging handle is pivotable within the charging handle bracket from a rest position to an operating position and vice versa. Furthermore, the charging handle bracket can be selectively mounted and dismounted without tools on either the left or right side of the charging handle housing. Problem and solution of the invention

[0028] Against this background, the object of the invention is to provide an alternative, structurally simple and functionally reliable receiver for a self-loading firearm. In particular, the object of the invention is to provide a receiver that enables simple and reliable cocking. Furthermore, the object of the invention is to provide a self-loading firearm with such a receiver.

[0029] This problem is solved by the subject matter of independent claims 1 and 18.

[0030] The invention therefore relates to a weapon housing with a first guide track within which a charging handle is movable for moving a charging tube that can be brought into contact with or is in contact with the bolt. The weapon housing is suitable for a self-loading firearm that has a bolt guided longitudinally within the weapon housing. The weapon housing is characterized by a second guide track connected to the first guide track via a first recess in the weapon housing, within which the charging handle is movable for moving the charging tube, so that the charging handle can be operated either from the left or right side.

[0031] The self-loading firearm according to claim 18 is characterized in that it is equipped with such a weapon housing.

[0032] By providing a second guide track connected to the first via a recess, the charging handle can be advantageously operated from either the left or right side. To do this, the user simply needs to flip the charging handle from left to right or from right to left. Because flipping the charging handle requires no modifications or additional tools, a charging device that can be operated from either the left or right side of the weapon can be provided with simple design elements, adapting to the shooter's ergonomics, particularly for left- or right-handed users. Ambidextrous operation is a criterion frequently required in public tenders today.

[0033] The invention is further distinguished by the fact that the charging handle can be changed very quickly from the first to the second guide track and vice versa, as this can be done without modification or tools, as already mentioned. A major advantage is that the weapon can be transferred from a left-handed to a right-handed user and vice versa, and the new user can quickly adapt a weapon that was not originally designed for them to their needs. This time saving is particularly advantageous in an operational situation, such as combat.

[0034] Additionally, the second guide rail and the first recess result in a weight reduction, allowing for a lighter weapon receiver or a lighter self-loading firearm. Furthermore, loading operations can be performed with the weapon on safe, ensuring drop safety.

[0035] The process of moving the charging handle from the first guide track to the second guide track, and vice versa, is called charging handle flipping. Charging handle flipping can be performed with the weapon unloaded, partially loaded, or fully loaded. It can also be performed with the weapon on or off safe.

[0036] The first and second guide slots can be designed, in particular, as a slot running lengthwise along the weapon housing, a so-called longitudinal slot. The charging handle is arranged to be movable longitudinally within the guide slots between two end positions, namely between a front end position and a rear end position. The two guide slots are expediently arranged symmetrically to each other.

[0037] The first recess can be, in particular, an opening in the upper receiver that connects the two guide tracks. The first recess can, for example, connect the front sections of the first and second guide tracks, especially the area where the charging handle reaches its forward end position.

[0038] However, it is preferred if the first recess connects the rear portion of the first and second guide tracks, in particular the area where the charging handle assumes its rear end position. If the recess is located in this area, the actuation of the charging handle can advantageously be combined with the racking of the weapon, so that racking and actuation can be performed in one movement. Furthermore, the rearward arrangement prevents unintentional actuation, as the user must consciously move the charging handle against the force of the recoil spring to actuate it.

[0039] In a preferred embodiment of the invention, the first and second guide tracks each have a recess for locking the charging handle, so that the charging handle can be locked on the left or right side of the weapon housing. The respective recess is specifically designed to hold the charging handle in the rear position, for example, to allow a view into the chamber.

[0040] It is particularly advantageous if the respective recess is provided in the same opening that connects the first guide track to the second guide track. This allows the charging handle to be quickly switched from its locked position.

[0041] In a structurally simple design, the respective recess extends towards the muzzle of the weapon housing, in particular a semicircular shape. The term "semicircular shape" can also encompass U-shaped and / or V-shaped shapes or geometries. Furthermore, the choice of recess geometry can depend on the geometry of the charging handle.

[0042] Preferably, the two recesses are separated by a housing section of the weapon receiver, with the housing section projecting beyond the two recesses towards the stock of the weapon receiver. Such a housing section can reduce the risk of unintentionally engaging the charging handle.

[0043] The extent of the first recess between the receiver section and the section of the receiver opposite it must be greater than the portion of the charging handle that passes through the first recess. A ratio d of the recess extent d1 to the corresponding extent d2 of the charging handle 1 < d < 2.0 is advantageous, where d = d1 / d2.

[0044] A ratio in the range of 1.0 < d < 1.5 has proven to be a good compromise between preventing unintentional and intentional activation of the locking lever. A ratio of approximately 1.2 has proven particularly advantageous in this context.

[0045] In a preferred embodiment of the invention, a locking device is provided with a locking element which can be moved from a first position to a second position and vice versa, wherein the locking element in the first position prevents the transfer of the charging lever from the first guide track to the second guide track or vice versa, and in the second position allows this transfer, and the locking device is configured to hold the locking element at least in the first position.

[0046] The safety device may be provided to prevent unintentional activation of the charging handle. Unlike the ratio d described above, the safety device defines a mechanical lock or constraint that must be actuated by the user before the charging handle is activated.

[0047] The locking device is configured at least such that a locking element is held in the first position, i.e., the position in which it prevents the device from being flipped. Preferably, the locking device is additionally configured such that the locking element is also held in the second position, i.e., the position in which it is allowed to be flipped. However, it is conceivable that the user could instead manually hold the locking element in the second position using appropriate handling.

[0048] In a structurally simple embodiment, the locking element is arranged on the weapon housing or on a component connected to the weapon housing. It is particularly preferred that the locking element is arranged in or on a profile rail located on the top surface of the weapon housing. The Picatinny rail is an example of such a profile rail. The Picatinny rail is a toothed rail standardized according to NATO standards for the quick and repeatable mounting of accessories on firearms. It is particularly preferred that the locking device or locking element be mounted on the end face of the profile rail or on a component connected to the end face of the profile rail. This advantageously avoids interfering with the mounting of accessories that typically extend vertically and then horizontally.

[0049] The locking element can in particular be designed as a locking pin, which in particular has a circular or polygonal cross-section.

[0050] In a structurally simple embodiment, the locking element is arranged to be longitudinally movable and is spring-mounted. It can be moved from the first position to the second position by pushing against the spring force and from the second position to the first position with the force of the spring. The longitudinally movable arrangement on the end face of the profile rail has proven particularly advantageous. This arrangement allows for easy handling by both left- and right-handed users.

[0051] Alternatively, the locking element can be mounted on a hinge and pivot about an axis from the first position to the second position and vice versa.

[0052] In the presence of the longitudinally movable and spring-loaded arrangement, it is preferred that the locking device comprises a gear mechanism that interacts with the spring in such a way that the locking element can be held in the first position and in the second position without the application of an external force. Such a mechanism is, in principle, similar to that of ballpoint pens.

[0053] For example, by pressing the safety mechanism against the spring force in a longitudinal direction, the charging handle can be depressed until it audibly and / or tangibly clicks into the second position. Pressing the safety mechanism again or activating a release mechanism unlocks it from the second position, and the spring force moves it back to the first position.

[0054] In a preferred embodiment of the invention, the weapon housing has at least one detent for engaging a detent element of the charging handle, such that the charging handle can be locked in both the first and second guide grooves on the weapon housing during a bolt movement. The detent element and the charging handle are preferably formed in one piece, with the detent element being designed, in particular, as a detent lug. For example, a further recess, a groove, or the like can be used as the detent.

[0055] If the charging handle is fixed to the receiver, then the charging tube, which is mechanically coupled to the charging handle, is also fixed to the receiver. Fixing the charging tube prevents it from moving back and forth within the receiver during use of the weapon and, in particular, prevents it from negatively affecting the locking function of the bolt.

[0056] It is preferred if at least one counter-stop is formed by a second and third recess in the weapon housing. This allows for a structurally simple design. The second and third recesses can, in particular, be arranged axially between the muzzle and the respective guide cam. It is especially preferred if the first guide cam and the second recess, as well as the second guide cam and the third recess, are arranged substantially aligned with each other in the axial direction.

[0057] Essentially aligned means that, for example, the upper end of each guide track and the upper end of the second or third recess are aligned with each other, i.e., form a straight line in the longitudinal direction. However, alignment in this context can also mean that, for example, only the lower end of each guide track and the lower end of the second or third recess are aligned with each other, i.e., form a straight line in the longitudinal direction. It is preferred if both the upper and lower ends of the guide tracks or the second and third recesses form a straight line in the longitudinal direction.

[0058] A second and third recess, arranged almost as an extension forward, is particularly easy to manufacture. Furthermore, a charging handle with a substantially constant profile thickness can be used, which also allows for a structurally simple charging handle.

[0059] Particularly secure engagement of the locking element, especially the locking lug, is achieved by making the second and third recesses polygonal, particularly rectangular. With such a second and third recess, it is advantageous for the locking element, especially the locking lug, to have a polygonal geometry corresponding to the second and third recesses.

[0060] Another aspect of the invention is to provide a profile rail for the weapon housing or for the self-loading firearm, which includes the safety device with safety element described above. Accordingly, a modified Picatinny rail is provided in particular.

[0061] The profile rail has a locking device with a locking element on its muzzle-facing end face, wherein the locking element can be moved from a first position to a second position and vice versa, and the locking device is designed to hold the locking element at least in the first position. At least in the first position, the locking element extends longitudinally along the profile rail to prevent unintentional movement of the charging handle.

[0062] Such a profile rail can be described as an "extended" Picatinny rail. The locking device is advantageously located on the end face so as not to interfere with the mounting of accessories on the profile rail.

[0063] The locking element can be designed, in particular, as a pin or bolt, preferably having a cylindrical, rectangular, or oval cross-section. The locking element can be arranged by means of or on an elastically deformable element. A spring is an example of an elastically deformable element.

[0064] In a first embodiment of the profile rail, it is provided that the locking element is arranged to be longitudinally movable and is 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.

[0065] A profile rail is particularly preferred if the safety device comprises a mechanism, such as a gear, that interacts with the spring in such a way that the safety element is held in the first and second positions without the application of an external force. Such a mechanism is advantageous because it leaves one hand free for the user to, for example, operate the charging handle while holding the self-loading weapon with the other hand. In the embodiment where the safety device only holds the safety in the first position, the user would have to manually hold the safety in the second position, for example, by means of a handle attached to the safety element and passing through a lateral recess in the front area of ​​the profile rail.

[0066] As an alternative to the longitudinally movable locking pin, it is preferred if the locking element is pivotally mounted and can be pivoted about an axis from the first position to the second position and vice versa. List of characters

[0067] Exemplary embodiments of the invention are explained in more detail below with reference to the accompanying schematic drawings: The drawings show: Fig. 1 a first perspective side view of a section of a weapon housing of a self-loading firearm in a preferred embodiment and the position of the charging handle in a first snapshot; Fig. 2 the position of the charging handle in a second snapshot; Fig. 3 the position of the charging handle in a third snapshot; Fig. 4 the position of the charging handle in a fourth snapshot; Fig. 5 the position of the charging handle in a fifth snapshot; Fig. 6 the position of the charging handle in a sixth snapshot; Fig. 7 the position of the charging handle in a seventh snapshot; Fig. 8 the position of the charging handle in an eighth snapshot; Fig. 9 the position of the charging handle in a ninth snapshot; Fig. 10 a second perspective side view of the section from Fig. 1and the position of the charging handle in a tenth snapshot; Fig. 11 a charging device in an exploded view; Fig. 12 the charging device of the Fig. 11 in a composite state; Fig. 13 a top view of an enlarged section of the front area of ​​the self-loading weapon according to Fig. 1 and the charging handle in a locked position in a section; Fig. 14 the charging handle of the Fig. 13 in an unlocked position; Fig. 15 a side view of the cutout.

[0068] The construction and function of the receiver for a self-loading firearm, which has a bolt guided longitudinally within the receiver, or the self-loading firearm with such a receiver, are explained below with reference to the figures. The figures show preferred embodiments of the invention.

[0069] Reference symbols are not consistently included in all figures to avoid compromising clarity. However, the same reference symbols apply to all figures throughout.

[0070] Fig. 1Figure 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, by way of example, the Universal Submachine Gun (UMP), a blowback-operated, recoil-operated weapon of the applicant. The section shows the left side of the self-loading firearm 100, or the weapon housing 10. Fig. 1 It also represents a first snapshot.

[0071] The receiver 10 of the self-loading weapon 100 has a first guide cam 11 designed as a longitudinal slot and a second guide cam 12 designed as a longitudinal slot opposite the first guide cam 11, the second guide cam 12 being concealed by the receiver 10 in this view. The first guide cam 11 and the second guide cam 12 are connected to each other by a first recess 13. The first recess 13 is located in the rear region of the guide cams 11 and 12.

[0072] The self-loading weapon 100 further features a charging handle 20 guided within the first guide track 11, which is mechanically coupled to a charging tube 21. The charging handle 20 is arranged to be longitudinally movable within the first guide track and has a grip 22 by means of which a user can move the charging handle 20. Fig. 1Figure 1 shows the charging handle 20 in its forward end position. From this position, the charging handle 20 can be moved rearward in the direction 98, thereby bringing the charging tube 21 into mechanical contact with the bolt and moving the bolt rearward against the force of the recoil spring. When the charging handle 20 is moved to its maximum extent in the direction 98, it is in its rear end position. The movement of the charging handle in the direction 98 corresponds to the movement toward the stock.

[0073] The first and second guide cams each have a recess for locking the charging handle 20, so that the charging handle 20 can be locked on the left or right side of the weapon housing 10. If the charging handle 20 is rotated from its rear position around the axis of rotation of the charging tube 21, it can be securely held in a first recess.

[0074] Opposite the first recess 14, i.e. on the right side of the weapon housing, a second recess 15 is provided, which allows the charging lever 20 to be locked if it is guided in the second guide track.

[0075] The recesses 14 and 15 are provided in the recess 13, i.e., the recess that connects the first guide track 11 with the second guide track 12. In other words, the recesses 14 and 15 are part of the first recess 13.

[0076] The recesses 14 and 15 each have a semicircular extension pointing in the direction 99, i.e., longitudinally forward. The movement of the charging handle in the direction 99 corresponds to the movement towards the muzzle 50.

[0077] The first and second recesses 14, 15 are therefore separated from each other 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 stock.

[0078] The weapon housing 10 also has a profile rail 30 on its upper surface, which is intended for mounting accessories. A locking device 40 with a locking element 41 is provided at the front end of the profile rail 30. According to this embodiment, the locking device 40 is an integral part of the profile rail 30. In this respect, it is an "extended" Picatinny rail. However, the locking device 40 can also be provided as a separate component. For example, it is conceivable to provide the locking device 40 as a modular accessory that is mounted at the front end of a known Picatinny rail.

[0079] The locking element 41 is designed as a cylindrical pin located on the end face 42 of the locking device 40 or the profile rail 30. The locking element 41 can be moved from a first position to a second position and vice versa. In the first position, the locking element 41 prevents the transfer of the charging handle 20 from the first guide track to the second guide track 12 or vice versa, while in the second position it allows this transfer. The locking device 40 is also configured to hold the locking element 41 in both the first and second positions.

[0080] For this purpose, the locking element 41 is arranged to be longitudinally movable and is spring-mounted (not shown). The locking device 40 further comprises a gear mechanism (not shown) which interacts with the spring in such a way that the locking element 41 can be held in the first position and in the second position without the application of an external force.

[0081] Fig. 1 The safety element 41 is shown in the first position. In this position, it is not possible to move the charging handle 20 from the first guide track 11 to the second guide track 12.

[0082] To engage the charging handle 20, the user moves the safety element 41 in the direction of 98 until it engages. The safety element 41 is now in the second position. The charging handle can now be engaged. The safety element 41 can then be moved from the second position to the first position by pushing it again in the direction of 98.

[0083] The weapon housing 10 further comprises at least one detent for engaging a locking element of the charging handle. When the charging handle 20 with its locking element is engaged in the detent, the charging tube 21 is fixed to the weapon housing 20 and does not move during movement of the bolt. According to this embodiment, the detent is formed by a second recess 17 and a third recess 18 in the weapon housing 10. The second recess 17 extends forward along the first guide track 11 and is thus axially located between the muzzle 50 and the first guide track 11.

[0084] The second recess 17 has a longitudinally extending rectangular shape, with the upper boundary of the second recess 17 and the upper boundary of the first guide track forming a straight line. The third recess 18 is concealed by the weapon housing. It is arranged symmetrically to the second recess 17 on the right side of the weapon housing 10.

[0085] In the position shown of the charging lever 20, the detent element of the charging lever 20 is engaged in the third recess 18.

[0086] The charging handle 20 is pivotally mounted on a spring within the charging tube. To release or unlock the locking lug from the third recess, the grip is moved backward. The charging handle 20 is arranged in the charging tube such that a backward movement initially causes a pivoting movement about a vertical axis, thereby disengaging the locking lug from the third recess 18.

[0087] As already mentioned, shows Fig. 1 the charging handle in the forward end position. Based on the following Figures 2 to 10 The process of moving the charging lever 20 from the first guide track 11 to the second guide track 12 is explained. The following Figures 2 to 10 represent snapshots taken in succession over time.

[0088] Fig. 2 This represents a second snapshot and shows the charging handle 20 or the grip 22 in the first guide track 11 in its rearmost position. The locking spring of the bolt is now maximally compressed. The user's hand holding the grip 22 is not shown.

[0089] Fig. 3This represents a third snapshot. The cocked charging handle 20, after a pivoting movement to the right and a forward movement 99, is engaged in the first recess 14. The first recess 14 surrounds the charging handle 20, preventing it from sliding down out of the first recess 14. The user can now release the grip.

[0090] Fig. 4 This represents a fourth snapshot. The cocked charging handle 20 remains engaged in the first recess 14. However, the safety pin 41 of the safety device 40 has now been moved from the first position, in the direction of arrow 98, to the second position. To do this, the user manually pressed the safety pin 41 in until it clicked into place. The safety device holds the safety pin in the second position. With the safety pin 41 in the second position, it is now possible to move the charging handle 20.

[0091] Fig. 5This represents a fifth snapshot. The charging handle 20 or the grip 22 is led out of the first recess 14 in the direction of 98 and is now folded to the right.

[0092] Fig. 6 shows a sixth snapshot, which shows the charging lever 20 or the grip 22 in the middle, i.e. between housing section 16 and safety element 41.

[0093] Fig. 7 This shows a seventh snapshot. The charging handle 20, or rather the grip 22, is now partially folded to the right. In this snapshot, the grip 22 is still being held by hand in the area of ​​the second recess 15.

[0094] Fig. 8 An eighth snapshot is shown. The charging handle 20, concealed by the weapon housing 10, and the grip 22 are now in the second guide track 12 in the rear end position, analogous to the position of the charging handle 20 in Fig. 2 .

[0095] Fig. 9This shows a ninth snapshot. The locking pin 41 has been moved from the second position back to the first position.

[0096] Fig. 10 This shows a tenth snapshot. This view shows the weapon housing 10, or the self-loading weapon 100, from the right side. The charging handle is now in its forward end position within the second guide track 12. The locking lug of the charging handle 20 is engaged in the opposite second recess 17.

[0097] The charging handle 20 has now been moved from the first guide track 11, through the first recess 13, into the second guide track 12. Moving the charging handle 20 from right to left is accomplished in the same manner.

[0098] It should be noted that the steps described above can also be carried out in a different sequence. For example, moving the locking device 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 handle in recess 14. It can also be flipped without engaging the respective recess 14 or 15. However, it is advisable to engage the charging handle 20 in the respective recess 14 or 15 if the safety pin 41 has not yet been moved to the second position.

[0099] Fig. 11Figure 1 shows an exploded view of the charging device. The charging device comprises an essentially L-shaped charging lever 20, which has a profiled grip 22 at one end of its legs and a locking element 23 designed as a detent lug at the other end of its legs. The detent lug is directed forward, i.e., in the direction 99.

[0100] The charging lever 20 can be operated by a (in Fig. 11A concealed elongated hole is inserted laterally into the charging tube 21. A torsion spring 24 is arranged such that one leg rests against the charging tube 21 and the other leg rests against the charging lever 20. A pin 25, which passes through the coil of the torsion spring 24 and corresponding bores in the charging lever 20 and charging tube 21, secures the charging lever 20 to or within the charging tube 21. The pin 25 also forms the axis about which the charging lever 20 can pivot against or with the force or torque of the torsion spring 24. The torsion spring is pre-tensioned so that it always exerts a torque on the detent lug 23 in the direction of the second or third recess 14, 15 opposite the grip 22. This ensures that the charging lever 20 always engages securely in the forward end position.Against the force of the torsion spring 24, the locking lug 23 can be led out of the corresponding recess 14, 15 by the user, for example to carry out a charging operation or to move the charging lever.

[0101] The charging tube has, on the side opposite the concealed elongated hole, another elongated hole 26 and an open elongated hole 27, which are separated by a web 28. A portion of the charging lever 20 can be moved through the longitudinally extending elongated hole 26. In other words, the elongated hole 26 provides a pivot radius for pivoting the charging lever 20. The locking lug 23 can engage in the second or third recess 14 or 15 through the elongated hole 27. A section 29 of the charging lever 20 can bear against the web 28.

[0102] Fig. 12Figure 1 shows the charging handle 20 and charging tube 21 in an assembled state in a perspective view. Also visible are the grip 22, the pin 25, the elongated holes 26 and 27, and the bridge 28.

[0103] Fig. 13 shows a top view of the weapon housing 10 as well as the one in Fig. 11 and 12 The charging device described in more detail is shown in a cross-sectional view. To the left of the weapon housing is the first guide track 11 and, extending from it, the second recess 17. To the right of the weapon housing is the second guide track 12 and, extending from it, the third recess 18. The charging lever 20 is guided in the first guide track 11 and is in its forward end position. The locking lug 23 of the charging lever 20 is engaged in the third recess 18.

[0104] For this purpose, the locking lug 23 is pressed through the elongated hole 27 of the charging tube 21 by the spring torque of the (not shown) torsion spring. The locking lug 23 engages through the elongated hole 27 into the recess 18 and rests against a limit of the recess 18. Thus, the charging lever 20, and therefore the charging tube 21, is fixed to the weapon housing 10. The charging lever can pivot about the axis of the pin 25 and can be unlocked by pivoting the grip.

[0105] Fig. 14 shows the charging lever of the Fig. 13in an unlocked state. For this purpose, the grip 22 was first pivoted in the direction of arrow 97 about the axis of the pin 25 and then moved in the direction of 98. It is clearly visible in this view that the third recess 18 extends further to the rear on the outside of the weapon than on the inside. In other words, the third recess 18 has a trapezoidal cross-section. This profile, which tapers from the outside to the inside, ensures a secure engagement of the locking lug 23 and makes it more difficult for the locking lug 23 to be unintentionally unlocked when locked. The second recess 17 has a corresponding geometry, i.e., also a trapezoidal cross-section.

[0106] Fig. 15 shows the section of the Fig. 13In a vertical section, the charging handle 20 and charging tube 21 are shown in their forward end position in an unlocked state. This view clearly shows that the locking element 41 completely covers the first recess 13 axially and at least partially covers the housing section 16 of the weapon housing 10. However, it is also conceivable to provide a locking element that only partially covers the recess 13. For example, depending on the thickness of the charging handle 20, it is sufficient if the locking element 41 covers only half, two-thirds, or an intermediate portion of the recess 13.

[0107] Figs. 16 to 19 show the weapon housing 10 or the self-loading firearm 100 in a complete view, whereby Fig. 16 and 18 a perspective from the left side or a perspective from the right side and Fig. 17 and 19show a side view of the left or right side of the self-loading firearm.

[0108] The charging handle 20 or the grip 22 is guided in the first guide track and is in the locked position in the forward end position. The extended Picatinny rail 30 includes the safety device 40 with a locking pin 41, which is in the first position. In this position, the charging handle 20 or the grip 22 cannot be moved. The second recess 17 is arranged in line with the first guide track 11. The locking pin 41 projects beyond the recess 13, which connects the first guide track 11 with the second guide track 12. The stock 60 is arranged opposite the muzzle 50. For further details, please refer to the descriptions in [reference to be added]. Fig. 1 referred.

[0109] Fig. 20 Finally, the self-loading firearm 100 or the weapon housing 10 of the Fig. 17, however, without a charging handle. It is thus clearly visible that the first guide cam 11 and the second recess 17 are arranged axially symmetrically and, moreover, aligned with each other. The same applies to the second guide cam 12 and the third recess 18.
