Definitions
- the present invention relates to a machine gun, the feed system and the carcass of such a machine gun.
- the ergonomics of a weapon is a rather particular concept in the sense that it brings together a number of criteria ranging from the mass and the size of a weapon to its grip in shooting conditions and conditions. handling. It is generally accepted that a weapon with better ergonomics is a weapon that allows the user to better fulfill his role within his unit. An improvement in the ergonomics of the weapon can be translated in different ways on the ground. It can lead to an increase in user mobility, an improvement in the availability of the weapon on the ground, an easing of the use of the weapon ...
- a machine gun is understood to mean a firearm capable of firing a band of ammunition, as opposed to firearms being fed from a magazine (rifle or pistol).
- the ammunition strip consists of a series of cartridges linked together by links, said links being detached from each other when the cartridges are extracted.
- the carcass of a machine gun is the central piece of the weapon, which serves as both main structural element, but also a reference base for the positioning of all the inserts or assemblies that perform the cycle of operation of the weapon.
- the functions related to the feeding band are present in the upper part of the weapon.
- the ammunition band being Manually placed on a feed chute before being held by different elements in the feed cover.
- the main advantage of this configuration is that it facilitates the handling of rearming and resolution of firing incidents by the horizontal positioning of the supply corridor as well as by the good accessibility, both visual and touched, elements achieving power functions.
- a disadvantage of this architecture is that, sighting systems being placed above the barrel, it is necessary to partially integrate (mechanical sighting eyecup handlebar) or completely (modular sighting devices mounted via a standard rail Picatinny) on the power supply cover of the weapon. This results in a certain inaccuracy in the alignment of the aiming point and the point of impact of the projectiles because of the uncertainty on the repositioning of the feed cover at each opening and closing thereof.
- the optics do not go above the power supply cover to allow the opening of the latter.
- This limitation also applies to the alignment of several optical components (light intensifier in front of a conventional sighting device ).
- the front member must, in this case, be mounted on the cover (this which brings the drawbacks mentioned above concerning the limitations of the sighting devices mounted directly on the power supply cover), or be mounted in front of the power supply cover which considerably distances the two optical devices.
- the carcass of a machine gun is made by assembling intermediate components. The goal is to be able to accurately perform the finishing machining of different parts before assembling them.
- the different components have an "open" shape that allows access to cutting tools (for milling or turning). For machine guns this opening is generally made in the upper part of the carcass because it will be covered by the supply cover which is removable to allow the establishment of a new band.
- the ejection of the links is generally performed by the dynamic band moving: when the band is pushed by its advance mechanism, the link released from its cartridge is directed to its window ejection out of the carcass.
- the last cartridge fed there remains 2 links to eject. No mechanism is provided for this particular case of the last cartridge.
- the main risk of this mode of operation is to allow a link to enter the interior of the carcass through the opening of the supply corridor which allows the passage of the lock and the cartridge. If a link falls inside the carcass it will cause a shooting incident by blocking the movement and mechanism of the parts included inside the weapon. This risk is increased if the machine gun feed chute is tilted from the horizontal: gravity can then direct the link to the opening of the feed chute.
- a second problem is that the last link usually remains on the supply corridor, the soldier must usually "clean" it before positioning a new band, and there is therefore a loss of time associated.
- the movable lid disposed on the top of the weapon prevents the reliable positioning of fixed accessories such as a telescopic sight;
- one or more links generally remain in the corridor, and the shooter must generally evacuate these links before being able to recharge;
- the positioning of the band, and in particular the positioning of the first cartridge is not accurate and may also lead to shooting incidents;
- a first aspect of the invention relates to a machine gun comprising an ammunition strip feed passage and a supply passage cover whose closing movement induces an adjustment of the longitudinal position of the ammunition strip. in the supply corridor.
- the adjustment of the longitudinal position of the strip in the corridor is obtained via an element for pushing the strip in the feed corridor during the closing movement of the lid, and allowing the passage of the strip during subsequent firing cycles (non-return ratchet).
- the non-return ratchet is integrated in the lid, and the closing movement of said cover comprises a component parallel to said feed passage, so as to allow a precise adjustment of the first munition.
- the parallel component of the closing movement of the lid is obtained by an axis of rotation of the secant lid relative to the plane of the supply corridor.
- the feed passage and its cover are arranged laterally, inclined relative to the vertical, the opening axis of the lid being substantially vertical.
- the machine gun according to the invention comprises, on its upper face, a fixed attachment assembly interface, this interface may preferably include a Picatinny type rail.
- a rod system actuating the anti-return ratchet is integrated in the carcass or cover to push the band to its loading position when closing the lid.
- the rod or rods actuating the pawl may for example be set in motion by a button or a lever protruding from the carcass or lid actuated by the closure.
- a second aspect of the invention relates to a mechanism for feeding a firearm fed by an ammunition strip comprising a mechanism for ejecting the last two links of said band.
- this mechanism comprises a movable pawl pushing on the penultimate link and actuated by the moving parts of the machine gun.
- the mobile ratchet ejection of the last two links is secured to the traction mechanism of the band.
- the tape traction mechanism comprises a movable pawl pushing, in use, against a munition, said pawl pushing against the ammunition and the ejection pawl of the last two links being actuated by the same lever actuated by the movement of moving parts of the machine gun.
- the ejection pawl of the last two links and the advance pawl can be made in one piece or separate. Preferably, it is two pieces rotating about the same axis and secured via an elastic piece such as a spring or a leaf spring.
- the tape traction mechanism comprises a star engrainant, in use, on the cartridges and the ejection mechanism of the last two links comprises a second star engrainant, in use, on the links.
- the two stars revolve around the same axis.
- the connection between the two stars is ensured by an elastically deformable element such as a torsion spring or a pin of elastic material (elastomer) passing through the web advance star and the star of ejection.
- the ejection means of the last two links comprise a flexible claw mounted on a spring and pushing on the last link to eject it.
- the flexible claw is mounted on a spring whose energy serves for the ejection of the last link.
- the portion for ejection of the link of the flexible claw comes into contact with a link when the link is not linked to a munition.
- the claw is held in a position intermediate, when a munition is present, by the non-return ratchet which occupies an extreme position when it no longer leans on a munition (ie at the end of the band).
- the flexible claw is resiliently connected to valves holding links and ammunition in the supply corridor.
- the flexible claw is linked to an indicator of the presence of ammunition station in the supply corridor.
- a third aspect of the invention relates to a machine gun comprising a supply corridor comprising a main sliding surface of an ammunition strip, lateral faces guiding, in use, the ammunition strip, and one, or web holding surfaces positioned at the upper edge of the side faces, said holding surfaces facing the sliding surface and said holding surfaces being open, so as to allow the introduction of the ammunition strip.
- At least one of the or the holding surfaces is retractable, leaving free at least one upper edge of the side faces, so as to facilitate the positioning of an ammunition strip.
- the or the holding surfaces are narrow and elastic, allowing introduction "in force" of the band.
- the retaining surface or the band belong to the slideways along the upper edges of the side faces of the feed passage, at least one of these slides being retractable.
- the retractable slide (s) are maintained along the lateral faces of the feed passage by elastic means.
- the retractable slide or slides have an inclined upper surface allowing the introduction of the ammunition strip by simply pressing it against the inclined surface of the slideway.
- the retractable slide or slides have a chamfer in the portion corresponding to the entrance of the strip in the corridor. power supply allowing the removal of a strip of ammunition by the torsion of the strip.
- a fourth aspect of the invention relates to a firearm comprising a carcass body having a substantially tubular geometry.
- the firearm comprises a feed passage and a lid arranged laterally, inclined outwardly with respect to the vertical, the opening axis of the lid being substantially vertical.
- the firearm according to the invention comprises, on its upper face, a fixed attachment assembly interface, this interface may preferably include a Picatinny type rail.
- Figure 1 shows a side view of a machine gun according to the invention.
- Figure 2 shows a perspective view of an example of supply corridor according to the invention, open cover, an ammunition strip in place.
- FIG. 3 represents a perspective view of an example of a feed passage according to the invention, open cover, without ammunition strip.

- FIG. 14 represents a claw advancing the band and ejecting the last link according to an example of the invention.
- FIG. 15 represents an example of a machine gun carcass according to the invention.
- Figure 16 shows an exploded view of a supply corridor according to the invention.
- FIG. 17 represents an exploded view of a feed corridor cover according to the invention.
- FIG. 18 represents a perspective view of another example of a supply corridor comprising means for repositioning the strip.
- FIG. 19 represents an exploded view of the corridor of FIG. 18.
- Figures 20 and 21 show sectional views of the device comprising the corridor of Figures 18 and 19, showing the movement induced by the closure of the lid.
- the term longitudinal when referring to a feed corridor, or the movement of a strip of ammunition relates to the direction of travel feeding the band, the barrel is therefore in the transverse direction relative to the longitudinal direction of supply of the weapon.
- FIG. 1 represents an example of a machine gun according to the invention.
- This machine gun has a lateral feed allowing the use of a Picatinny type rail 21, continuous and fixed on the top of the carcass body 22.
- On top we mean the upper part when the weapon is used according to a conventional position .
- other types of accessory attachment interfaces could be used.
- Figure 2 shows a perspective view of the supply corridor with a munition strip 5 positioned, 2 open lid.
- This lid comprises closure means 19 cooperating with corresponding means on the carcass 22.
- FIG. 3 shows the same corridor, without the ammunition strip 5, which makes it possible to distinguish the pawls 15 and 14, pushing respectively on the anterior part of the penultimate munition, and on the central portion 10 of the penultimate link.
- These pawls 14, 15 project from the sliding surface 3 of the ammunition strip 5. As will be seen below, the central position of the pawl 14 can eject the last link.
- This horizontal component allows a non-return ratchet 12 to push on the second-to-last munition (or rather here on the central part of the penultimate link) This positioning movement is better illustrated in the sections of FIG. 5.
- the lid is not yet closed, and the band rests on the feed pawls of the strip 16, 15.
- These pawls 15, 16, free to rotate about their axis do not allow precise positioning of the band.
- a positioning too low of the last ammunition ie the ammunition is not "post” positioned in the middle of the opening of the supply corridor.
- the position of the feed pawls depends on the position of the latch 17 and the moving parts, which is not unambiguous when placing the strip, in particular in the case of weapons operating with open yoke: the lock 17 can be in the front position, empty chamber and locked, or the latch 17 is in the rear position, empty chamber.
- the ratchets 14, 15, 16 advancement will be at different positions.
- the repositioning of the strip can be obtained in other ways, the essential being that the closing movement of the cover can induce a readjustment movement of the strip parallel to the sliding thereof.
- the strip 5 slides on a horizontal surface 102 and is correctly positioned by non-return pawls 101 actuated by the closure of the lid 107.
- the non-return pawls 101 are fixed on a slider 103 comprising an inclined surface 105 cooperating with a corresponding inclined surface 106 on the cover 107.
- the non-return pawls 101, 12 can be erased to let the successive ammunition 18 in the normal direction of feeding .
- the inclination at 45 ° of the sliding plane 3 of the supply corridor has the advantage already cited of allowing, in combination with the axis of rotation 4 of the vertical cover, the adjustment of the ammunition to post . Moreover, this inclination makes it easier to position the band, by hanging the band on the advancing ratchets 14, 15, 16 either by keeping the weapon upright (which is not possible for vertical feed weapons), or by tilting the weapon by only 45 ° to position the horizontal lane . It is understood that other angles of inclination are possible, provided that the lateral space is sufficiently limited, and that the horizontal component of the sliding plane 3 is sufficient so that the strip of stably on the advancing pawls 14, 15 16 without tilting the weapon. Reasonable angles of inclination are between 20 and 70 °, preferably between 30 and 60 °.
- FIGS 5 to 8 illustrate the operation of the power system of the example of the invention.
- the machine gun operates according to a cycle called "open yoke", a device in which out of shooting, the latch 17 and the moving parts are in the rear position, open chamber and empty.
- the complete cycle of a shot is then as follows: The release of the trigger releases the moving parts and the lock 17, which introduces the passage through its ergo 20 a munition 18 in the room. At the end of the forward movement, the lock is locked to the lock ring, behind the barrel chamber. This forward movement is induced by a compressed recovery spring during the backward movement of the moving parts. The ammunition is then impacted, and a gas recovery in the last section of the barrel can return the moving parts back by compressing the recovery spring.
- the moving parts After the firing of the last ammunition, the trigger being generally kept pressed, the moving parts make a last movement forward, and the weapon is found breech closed, empty room. Depending on whether the user reloads the mechanism before or after placing the ammunition strip, the moving parts are therefore in the forward or reverse position.
- Figure 5 shows the weapon in the waiting position, rearward moving parts, a stationary ammunition, the lug 20 of the latch 17 placed behind the ammunition station.
- the advancing pawls of the band 14, 15, 16 are in the lower position behind the penultimate ammunition, the band rests on the non-return pawl 12 and the holding valves 11 press on the links and hold the ammunition in position. in the middle of the opening of the supply corridor, ready to be fed by the latch 17.
- ejection claw 13 grows on the anterior lateral parts 9 of the penultimate link.
- the last ammunition is driven into the chamber by the lug 20 of the latch 17. During this movement, as soon as the ammunition is fully unmated, the feed pawls 14, 15, 16 begin. to advance.
- Figures 9 to 12 illustrate the ejection of the last two links, when firing the last ammunition.
- the last ammunition is stationary and the central part 10 of the last link rests on the non-return pawl 12.
- the lateral advancement pawls 15 and 16 no longer rely on ammunition and can no longer push on the rest of the band. Only the central pawl 14 is still facing the central part 10 of the penultimate link, which at the beginning of the cycle rests on the non-return pawl 12.
- the munition is loaded into the chamber.
- the claw 13 is no longer based on a munition, and, therefore, occupies an extreme position that it never occupies during a cycle in the presence of a band of ammunition. This movement to an extreme position can be used to move a tape indicator giving an indication of the absence of tape.
- Figure 13 shows a section of the supply corridor, with a stationary ammunition.
- retractable slides 6, 7 could be replaced by holding surfaces facing the sliding surface 3 directly fixed (see, forming part) to the side faces 23, 8 of the feed corridor, or these surfaces, the walls of the supply corridor being sufficiently flexible (s) to allow the "force" of the tape.
- FIGS 14 to 17 show different elements in perspective, so as to clarify the parts possibly hidden in the previous figures.
- Figure 14 shows a driving claw of the band.
- This claw has three pawls 14, 15, 16.
- the two side pawls bear directly on the penultimate ammunition, respectively forward and backward of the anterior lateral portions 9 of the antepenultimate link.
- Pawl 14 meanwhile pushes on the central portion 10 of the penultimate link.
- These three pawls 14, 15, 16 may be integral, or, preferably, the central pawl 14 is elastically connected to the other two pawls, for example via a torsion spring. Indeed there is a space between the ammunition which allows a greater range of motion for the side pawls 15, 16 than for the central pawl, blocked by the surface linking the successive links. Therefore, the support provided by the central ratchet 14 provides a less reliable support, and potentially prevents the lateral ratchets to take an optimal position. Detaching the central pawl 14 then allows an optimum range of motion for the lateral pawls 15, 16.
- the central pawl 14 is no longer blocked by the surface linking the successive links, and it can then take a more reliable support surface.
- the lateral pawls 15, 16 no longer rely on a munition, and therefore no longer participate in the movement of the band.
- Figure 15 shows a tubular carcass body 22.
- This closed geometry makes it possible to obtain a better rigidity, and in particular a better resistance to torsion than open profiles.
- the lateral positioning of the feed passage allows the fixing of a fixed Picatinny rail 21.
- the positioning of the carcass side band feed mechanism rather than in the lid allows a short-length lateral opening, which further improves the mechanical properties of the whole.
- Figure 16 shows an exploded view of the supply corridor. There are two springs 24 for holding slides 6, 7.
