Definitions

  • the invention relates to e.g. semi or fully automatic firearm with features as specified in claim 1.
  • Weapons of this type have been introduced in various armies, such as the G 3 in Germany or the M 16 in the USA, but these are proven weapons, but they have the disadvantage that the cartridge has to be driven out of the magazine in order to be inserted into the off-axis cartridge chamber to be transferred over a slope, which can lead to jamming of the cartridges during the loading process. Of course, this is particularly unsuitable for caseless ammunition because these cartridges are too sensitive.
  • "Firearm” includes firearms of any kind, including Cannons, heavy machine guns.
  • the magazine protrudes downward from the firearm.
  • the length of the magazine protruding from the firearm usually determines how far the shooter has to rise from the ground in order to be able to aim and fire with the firearm.
  • the shooter especially in very flat terrain, often has to rise more than his cover than would be necessary to look beyond the cover. He thus offers a larger target area for an enemy shooter when using his own firearm, simply because the magazine protrudes downward from the firearm, than would be necessary when using a firearm from which no magazine protrudes downward.
  • the General Electric 7.62mm Minigun Machine Gun (USA) has six tubes that rotate and are driven electrically.
  • the General Electric 25 mm light automatic cannon has two tubes that have two firing mechanisms that are automatically operated alternately. Both Constructions are only intended for several tubes.
  • the FN Minimi 5.56 mm machine gun (Belgium) can be equipped with either a magazine or a cartridge belt. This machine gun also has a tube.
  • the patent FR-A-493506 describes an auxiliary device for machine guns, which consists of a magazine and a drum, which has recesses on the circumference that do not align with the chamber of the machine gun.
  • This device is intended to enable an existing machine gun, particularly a Lewis machine gun, to hold a large number of cartridges in the magazine.
  • the drum is attached above the machine gun. It is not between the magazine and the chamber because the drum is positioned at the back but above the chamber.
  • the breech that moves below the drum, ie outside the drum's path of travel, is part of the machine gun, not the invention.
  • the cartridges fall down from the drum in front of the breech.
  • the rotating drum does not provide cooling because it is located above the weapon. Cartridge belts cannot be used.
  • At least one magazine or cartridge belt is used for stocking the cartridges, but when loading the firearm the top cartridge of the magazine or the first cartridge of the cartridge belt is not pushed diagonally upward into the chamber, for example, but by means of an intermediate transport drum, which does not necessarily have to have a round cross section, is first brought into a position behind the chamber and essentially flush with it, from where it is pushed axially forward into the chamber by means of the closure.
  • an intermediate transport drum which does not necessarily have to have a round cross section
  • the magazine does not have to be inserted directly into the fixed housing of the firearm, but possibly into a swivel sleeve which is present when a swivelable magazine is required and is otherwise superfluous, which is essentially coaxial to the transport drum, for example between it and the housing is arranged and can have extensions between which the magazine is inserted. Since this swivel sleeve can be pivoted together with the magazine around the longitudinal axis of the firearm, it is possible, for example, to pivot the magazine upward from the position projecting downward from the firearm into a laterally projecting position, which is generally the case with right-handed shooters will offer the left side, but the right side is also conceivable.
  • the angular division of the transport drum correlates with the angular difference between the individual positions that swivel sleeve and magazine can assume together to ensure that cartridges can be passed into the transport drum from the magazine in any ingestible position.
  • the magazine can be fixed radially to the housing at several positions, for example at the bottom and left. "Recesses" in the transport drum contains all kinds of cavities either on or within the circumference.
  • the transport drum can e.g. four recesses or a multiple of this distributed over the circumference to ensure that it is possible to fill the transport drum with cartridges from each of the two possible positions of the magazine.
  • the recess in the lower position from the magazine can be fitted with a cartridge the cartridge would move in this recess over the position on the left to the upper position, where it would be pushed into the chamber, fired with the help of the breech and, for example, a firing pin inside, and the empty sleeve would be fired into the same position, still in the recess located in the upper position would be pushed back, whereupon the transport drum would turn you again by 90 °, for example by at least one oblique plane protruding into the outer contour of the transport drum, the empty cartridge case can be removed from the recess before reaching the position on the right, for example , if the recesses on the Trom are located so that this recess is free to receive the next cartridge from the magazine when reaching the next, namely the position below.
  • the puller arranged at the front of the closure in the form of e.g. a hook, which engages in the annular groove at the rear end of the cartridge
  • the sleeve does not slide backwards into the recess in the housing which is intended for the closure, as a result of which the rotation of the drum would be blocked. Otherwise, this guide would have to be completely removed from the cartridge sleeve with the hook before it is transported further.
  • the opening in the housing of the firearm required to eject the empty sleeve is preferably closed by a pivotable flap which is attached to the housing.
  • the flap described above is omitted from the housing.
  • the inclined plane for pressing out the empty cartridge case from the transport drum can also be removed or is integrally connected to the housing in one piece.
  • cartridge cases in a conventional manner in e.g. the rear of the breech can be removed by extractors and ejectors
  • the transport drum can, for example, also be positioned such that the magazine opening or the openings of several magazines are located on the circumference of the drum, for example between two recesses with a design of a transport drum with several recesses, which in this example are on the circumference.
  • the cartridge is inserted into the transport drum when the transport drum is rotated or during the time in which the closure, for example when using a guide cylinder, is approximately in its rearmost position and the drum can come to a standstill.
  • the insertion time of the cartridges in the transport drum is significantly reduced in this example.
  • the magazine opening or cartridge belt opening can be positioned, for example, behind the transport drum in the longitudinal direction of the tube axis.
  • a radial extension of the breech or breech carrier or another device brings the cartridge, for example, when the breech is moved forward from the area of the magazine opening or cartridge belt opening into a recess which is approximately aligned with the cartridge in the magazine opening or cartridge belt opening.
  • the recess can be located on or near the circumference of the transport drum, for example.
  • a recess near the circumference of the transport drum can, for example, be a round hole which encloses part of the closure in its front position.
  • the transport drum can have, for example, a cross-shaped or star-shaped cross-section, can be made to a minimum in order to accommodate the recesses.
  • the breech extension can be dampened and, in contrast to conventional breech systems, touch a large area at the back of the cartridge so that caseless ammunition is not damaged. An almost straight supply into the chamber is ensured in this version, as well as the separation of the, for example, caseless ammunition from the cartridge fired in the chamber, which is necessary for caseless ammunition.
  • a device such as a linkage that activates a movable breech or breech carrier extension to push a cartridge forward into the transport drum when the loading lever is tensioned before the transport drum rotates can be used to ensure that the loading lever is pulled only once got to.
  • each tube can be fitted with a closure.
  • two closures can be put out of operation, for example by locking them further back like the guide grooves of the guide cylinder if a guide cylinder is used, so that one closure and one chamber can be activated and one closure in this Example of the movement of the transport drum is used.
  • all three closures would be in the rear part and would only move the guide grooves when they moved individually forward, so that two closures would be disengaged from the guide grooves when out of operation .
  • the transport drum can be provided with three recesses, for example on the circumference, in an embodiment with, for example, three chambers. Each recess can be fitted with a cartridge before it is essentially filled with one Chamber is brought in alignment. It is possible, in a version with, for example, three chambers, to firmly connect the three closures. If the magazine openings are located on the circumference of the transport drum, for example between two recesses, the magazines can be switched off by fitting the magazine openings, for example with an eccentric rod in the longitudinal direction of the magazine opening, which partially blocks the opening, or by allowing the cartridges to exit as desired.
  • a locking pin can be arranged in the housing, which then counteracts its spring preload from the extension attached to the bottom of the magazine is pressed at the back and blocks the tap when the magazine is empty and thus no cartridge slides out of the magazine into the lower recess of the transport drum.
  • This safety pin thus reports the empty state of the magazine, but can be pushed out of function by hand, that is, pushed forward again, if the existing cartridge or cartridges are to be deliberately fired from the transport drum.
  • This locking pin is intended to prevent that the transport drum is also completely empty and, when a full magazine is inserted, must first be loaded through before a cartridge is again in the chamber when the magazine is in the lower position.
  • the rotation of the drum can be effected, for example, in that a guide cylinder is arranged axially and in alignment with the actual transport drum and usually formed integrally with it, in the lateral surface of which, for example, individual guide grooves are incorporated in such a way that a guide pin protruding into these guide grooves extends from the closure arranged above the guide cylinder downwards, from each tip of the zigzag line, can only slide in a defined manner into the next guide groove.
  • the breech which can be operated by means of compression springs, can be brought back by means of a loading lever, for example for loading the firearm in order to bring the first cartridge into the chamber. This results in a section-by-section rotation of the transport drum which is non-rotatably connected to the guide cylinder.
  • the sliding of the guide pin into the next guide groove at each turning point can be realized, for example, in that the bottom of each guide groove approaches the outer surface of the jacket more and more in the direction in which the guide pin is to pass through it it opens into the beginning of the next guide groove, where the higher floor at the end of the first guide groove falls perpendicular to the lower floor at the beginning of the next guide groove, so that the spring-loaded guide pin must pass through the second guide groove after passing through this drop , the bottom of which increases in its course and exhibits the same drop when changing to the next guide groove.
  • the magazine and the swivel sleeve are also matched to one another in the case of a version with a swiveling magazine, for example between whose extensions the magazine with its open end will be inserted:
  • its inner contour can be dimensioned in this way be that the cartridges come in a double row one above the other and half next to each other.
  • This inner contour of the magazine can taper towards the upper open end and form a narrower neck, the inner contour of which is just wide enough for a single cartridge to pass through, thereby providing the necessary separation that is advantageous for loading the firearm.
  • the magazine In order to prevent cartridges from being lost from the magazine in a magazine that is not in a firearm, the magazine is in the normal state, for example, by means of two leaf springs which are attached to the side of the magazine and have an offset which partially protrude from one another over the open neck of the magazine , closed so far that no cartridge is pressed out of the magazine.
  • the prerequisite for this is, of course, that the tension of the leaf springs is sufficiently strong to hold the cartridges against the pressure of the magazine spring, which presses the cartridges towards the open neck.
  • These leaf springs do not lie close to the outer contour of the magazine, but keep a distance.
  • the offset of the leaf springs which partially close the open neck of the magazine, does not extend over the entire axial length of the leaf springs, but only over its beginning and end area, whereas, for example, a recess is provided in the middle area of the leaf springs instead of the offset.
  • the swivel sleeve in turn has mutually parallel and radially extending projections from the swivel sleeve, between which the neck of the magazine has to be inserted, at least two of these projections being arranged and dimensioned such that they slide through the recess in the cranks when the magazine is inserted
  • Leaf springs through between the leaf springs and the neck of the magazine slide, whereby the two leaf springs are pushed away from the neck of the magazine and the bends of the leaf springs move so far apart that the opening of the neck of the magazine is completely released, and the cartridges can be pressed into the recess of the transport drum.
  • the swivel sleeve has, for example, the shape of a tube piece, to which, for example, a box-shaped profile or parts of a box-shaped profile connect radially, both the tube part and the box-like attachment having to be broken through by the necessary openings for the cartridge ejection and the magazine insert.
  • FIGS. 1a and 1b show basic representations of an embodiment of a firearm 1 which is supplied with cartridges via a magazine 2.
  • this magazine 2 protrudes downward from the firearm
  • this magazine 2 is folded up to the left into the horizontal position, as would be done by a shooter who, with a foldable magazine in a lying position, has the smallest possible ground clearance wants to take.
  • Magazine is to be understood to mean all devices in this and other embodiments which are suitable for the supply of cartridges. Although only one such magazine is present in the exemplary embodiment described, it can be seen that in another embodiment of the invention, for example, two, for example, different magazines for, for example, different types of cartridges can also be present, which are not necessarily pivotable have to.
  • FIG. 2 shows a cut-away side view of such a firearm, which mainly shows the loading device 6.
  • the magazine 2 protrudes downward from the housing 4 of the firearm 1.
  • the ammunition is pressed out of the magazine 2 due to the spring force of the magazine spring 28 upwards in the direction of the transport drum 7 with its recesses 8.
  • This transport drum 7, which may consist, for example, of two or more connected disks with radial recesses, is arranged above the magazine 2 in such a way that an overlying recess 8 lies behind the chamber 5 and is essentially flush with it, into which the ammunition can be fired through the barrel 35 is advanced, as shown for example in Figure 3.
  • FIG 2 an empty magazine 2 is shown in the firearm 1, wherein a cartridge is neither in the transport drum 7 nor in the chamber 5.
  • 3 shows a cartridge 3 in the chamber 5.
  • the magazine 2 is not inserted directly into the housing 4, but into the extensions 12 of a swivel sleeve 11 which concentrically surrounds the transport drum 7, as can best be seen in FIGS. 5a and 5b.
  • the pivot sleeve 11 has at least the two extensions 12 lying parallel to the longitudinal axis 13 of the firearm 1, as can be seen in FIGS. 5a and 5b, whereas the two extensions 12 lying in front and behind, as seen in the direction of the longitudinal axis 13, as in FIG 2 and 3, possibly instead of being connected to the swivel sleeve 11, as shown in the present example, could also be connected to the housing 4.
  • the transport drum 7 has a certain number, namely in this case four axially lying recesses 8, which are suitable for receiving cartridges 3. If, for example, as shown in FIG. 5b, magazine 2 is in a position in which it protrudes downward from the housing 4 of the firearm 1, then a cartridge 3 is pressed from the magazine 2 into the recess 8 of the transport drum 7, which is in the lowest position.
  • a loading lever not shown, counterclockwise of the view shown in FIG.
  • the cartridge 3 migrates in the recess via the position on the right outside of the transport drum 7 in the top position, where it is aligned with the chamber 5, as shown in Figures 2 and 3.
  • the cartridge 3 is pushed forward by means of the breech 19 from the recess 8 of the transport drum 7 into the chamber 5 which is essentially in alignment therewith, where it is ignited and fired by means of the firing pin 17 arranged in the breech 19.
  • the firing pin 17 is actuated by opening the spring-loaded cock 36, which is released after actuation of the trigger 37.
  • the empty sleeve 33 located in the chamber 5 at the front of the closure 19 is pushed back into the same recess 8 of the transport drum 7 by the gas pressure or recoil together with the extractor.
  • the extractor 16 consists essentially of a hook 20 which engages in the annular groove 21 at the rear end of the cartridge 3 or sleeve 33.
  • the closure 19 is pretensioned by two compression springs 39 which are parallel to one another, so that one of these compression springs 39 can be seen in the illustrations of FIGS. 2 and 3.
  • the angular pitch 9 of the transport drum 7 is also the angular amount by which the transport drum 7 is rotated further, it is obvious that the angular pitch 9 of the transport drum 7 and the swivel angle 10 between the individual positions that the magazine 2 has with respect to the housing 4 can take, must be coordinated.
  • the magazine can assume two positions, which differ by a 90 ° angle, and the transport drum 7 is also provided with four recesses 8, each offset by 90 °.
  • FIGS. 1a and 1b or 5a and 5b The pivoting of the magazine 2, as shown in FIGS. 1a and 1b or 5a and 5b, is possible in that the magazine 2 is inserted into a component which also pivots, namely the pivot sleeve 11.
  • This swivel sleeve 11 is located concentrically between the transport drum 7 and the surrounding housing 4, and has the one in FIGS. 2, 3 and 5 visible extensions 12, which strive radially from the longitudinal axis of the swivel sleeve 11.
  • FIG. 7a shows a front view of the swivel sleeve 11 with one of the two extensions 12 lying transversely to the front view, which in FIGS. 2 and 3 are located in front of and behind the magazine 2 are recognizable.
  • FIG. 7b shows a top view of the swivel sleeve 11, in which the H-shaped opening can be seen, the longitudinal leg of which is necessary for the ejection of the empty sleeves 33 in the two positions which the swivel sleeve 11 can assume.
  • the transverse connection of the opening is necessary for the protrusion of the functional surfaces 32, which cause the sleeves 33 to be ejected.

  • FIG. 6 a shows in perspective how the magazine 2 is inserted between the extensions 12 of the swivel sleeve 11.
  • the shape of the leaf springs 27 is also drawn in a cross-sectional illustration of the magazine 2 in its normal position as well as in the position shown in broken lines and pushed apart. As can best be seen in FIG. 6b, these two leaf springs 27 in the normal position close the opening 31 of the hare 14 of the magazine 2 by means of their crankings 29 to such an extent that cartridges 3 are prevented from escaping. Of course, the force of the leaf springs 27 must be sufficient to retain the cartridges 3 despite the pressure shown from below, namely the magazine spring 28.
  • these leaf springs 27 do not lie tightly against the outside of the walls of the magazine 2 in the upper region of the neck 14 of the magazine 2, but instead are designed so that there is a distance between the leaf springs 27 and the walls of the magazine 2, in which the two, parallel to the longitudinal axis 13 of the firearm 1, approximately 12 in the middle of the pivot sleeve 11 arranged extensions 12 can engage.

  • the magazine 2 is positioned in the longitudinal direction with respect to the swivel sleeve 11 by the front and rear, additional extensions 12.
  • the rotary movement of the transport drum 7 is triggered by the movement of the closure 19. This is done in that, as shown in Figure 2, with the transport drum 7 axially aligned at least rotationally, if not in one piece, a guide cylinder 24 is arranged, as shown in Figure 2 only with its outer contour.
  • This guide cylinder 24 has the guide grooves shown in FIGS. 3 and 8b in its outer surface, into which the guide pin 26 engages, which is arranged in the closure 19 running over it.
  • these guide grooves 25 would form a zigzag line when the outer surface of the guide cylinder 24 was developed in one plane, the band of which extends transversely to the longitudinal axis 13 of the firearm 1.
  • the depth of these guide grooves 25 in the surface area of the guide cylinder 24 is not uniformly deep, as the section along VIII-VIII of FIG. 8b shown in FIG. 8c shows.

  • this is at its beginning again much deeper than the guide groove 25 opening into it at its end, so that at the transition from one guide groove to the next, a quasi-vertical drop from the higher floor at the end of the previous groove to the lower floor takes place at the beginning of the newly starting groove 25.
  • FIGS. 9a and 9b show such a closure 19 in side view and top view, the front view of which is drawn in accordance with X-X in FIG. 9b in FIG. 10.

  • the guide 18 may only encompass part of the circumference of the sleeve 33, since otherwise a further rotation of the sleeve 33 by the transport drum 7 in the direction of the functional surfaces 32 and thus the ejection from the housing 4 would be hindered.
  • FIG. 9a shows the guide pin 26 projecting downward from the closure 19, which is biased downwards by a compression spring (not shown) located in the closure 19, so that it always bears against the bottom of the guide groove 25 of the guide cylinder 24 is guaranteed.

  • the shutter 19 moves backwards and is no longer in the path of movement of the transport drum 7, the transport drum 7 rotates clockwise, as seen from behind.
  • the two remaining closures 19 are locked outside the guide groove 25 of the guide cylinder 24 so that the transport drum 7 can rotate.
  • Each magazine 2 and each closure 19, which corresponds to this, can be used individually. It can be seen that the three chambers 5 can be individually fitted with cartridges 3 by a magazine 2, as long as two closures 19 are out of operation.
  • a chamber 5 can be equipped with, for example, different cartridges 3 from two magazines 2. These magazines 2 can optionally be switched on and off by an eccentric rod 49 on the magazine turned off.
  • FIG. 16 A fifth embodiment of the invention is shown in FIG. 16.
  • a chamber 5 can be fitted with cartridges 3 from two magazines 2 which can be pivoted.
  • the transport drum 7 has a recess 8 which receives cartridges 3 at a rotation of approximately 180 °, e.g. when the closure 19 is approximately in its rearmost position and the transport drum has come to a standstill.
  • the magazines 2 are connected with a swivel sleeve 11, and can optionally be brought into the lowest position to accommodate cartridges 3.
  • a magezin 2 that is not used is blocked at the top to prevent cartridges 3 from escaping.
  • the transport drum can have several recesses 8.
