Definitions

  • the present invention relates to a weapon housing 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 weapon housing.
  • 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.
  • the shutter arrangement leads to the firing of shots whose bolt head, the top cartridge from the magazine in a known manner into a cartridge chamber in the barrel.
  • 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 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.
  • 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.
  • the shutter assembly returns, it slides over the magazine towards the stock.
  • 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.
  • a recoil loading mechanism can be used in a known manner for this cycle.
  • 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.
  • the breech (bolt carrier and breech head) is in its forward position before the shot is fired as shown above, i.e. 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.
  • the bolt 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.
  • 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.
  • the loading lever can be mounted and dismantled on the loading device without tools.
  • 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.
  • 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.
  • 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.
  • 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 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.
  • the EP 0 207 058 B1 discloses a non-rotating through-loading device with a non-convertible, laterally pivotable one-sided loading lever.
  • 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.
  • 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 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.
  • the charging lever holder can be mounted and dismantled in or on the charging lever housing either on the left and/or right side without tools.
  • the object of the invention to provide an alternative, structurally simple and functionally reliable weapon housing for a self-loading firearm.
  • 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.
  • the self-loading firearm according to claim 18 is characterized in that it is equipped with such a weapon housing.
  • the charging lever is advantageous Can 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. 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.
  • 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 located within the guide slots in the longitudinal direction between two End positions arranged movably, 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 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.
  • 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.
  • 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.
  • the respective recess has an extension pointing in the direction of the mouth of the weapon housing, in particular one semicircular extension.
  • 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.
  • 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.
  • 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 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.
  • 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. Different from the one described above Ratio d, 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 securing device is additionally configured such that the securing element is also held in the second position, i.e. in the position in which folding over is permitted.
  • the securing element is held manually in the second position by the user using appropriate handling.
  • the securing element is arranged on the weapon housing or on a component connected to the weapon housing.
  • 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.
  • 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.
  • 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.
  • the securing means comprises 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 action of an external force.
  • a mechanism or mechanics is, in principle, similar to that of retractable ballpoint pens.
  • the loading lever can be pressed in until it audibly and/or tactilely engages in the second position.
  • the securing element 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.
  • 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.
  • a further recess, a groove or the like can be used as a counter catch.
  • 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.
  • the at least one counter-catch is formed by a second and third recess in the weapon housing.
  • 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.
  • 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.
  • 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.
  • 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.
  • a further 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 a safety element described above. Accordingly, in particular a modified Picatinny rail is provided.
  • the profile rail has a securing device with a securing element on its end face pointing towards the mouth, the securing element can be moved from a first position to a second position and vice versa, and the securing device is designed 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.

  • Fig. 1 shows the charging lever 20 in its front end position. Starting from this position, the charging lever 20 can be moved backwards in the direction 98, 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 weapon housing 10 also has at least one counter-latch for engaging a latching element of the loading lever. If the charging lever 20 is engaged with its locking element in the counter-locking position, the charging tube 21 is fixed to the weapon housing 20 and does not move during movement of the breech.
  • 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.
  • 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.
  • FIG. 1 shows Fig. 1 the charging lever in the front end position.
  • FIG. 2 to 10 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 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.
  • 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.

  • 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.
  • 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.
  • 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.
  • the pin 25 also forms the axis about which the charging lever 20 can be pivoted against or with the force or moment of the leg spring 24.
  • the leg spring is inserted pretensioned 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.
  • the through-loading pipe 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. You can also see the handle 22, the pin 25, the elongated holes 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.
  • 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 lies at a boundary of the Recess 18.
  • 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.
  • 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.
  • the third recess 18 extends longer to the rear on the outside of the weapon than on the inside of the weapon.
  • 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.
  • Charging lever 20 and charging pipe 21 are therefore in an unlocked state in the front end position.
  • 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.
  • 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 the flipping of the Loading lever 20 or handle 22 is not possible.
  • 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 guide link 12.
  • 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.
