Definitions

  • the invention relates to a device for feeding cartridges to a height-adjustable firearm from a stationary cartridge magazine with a cartridge feed channel in which the ammunition is transported to the firearm.
  • a disk channel for example, is suitable as a deflection device.
  • a disk channel is described in DE-A-32 04 499.
  • the individual discs of the disc channel are rotatably mounted at three points.
  • the disks are connected to one another by a gearbox, the transmission ratio of which decreases from disk to disk.
  • these disks are connected to each other with the weapon and with a fixed channel by elastic connecting links.
  • a flexible channel can be used instead of a disk channel.
  • a flexible delivery channel is described in US-A-34,37,005. The ammunition is removed from the stationary container through a flexible delivery channel of a rapid-fire weapon, e.g. fed to a Gatling cannon, this flexible delivery channel being exposed to strong bends and twists.
  • the object to be achieved by the present invention is to provide a device for supplying cartridges to a height-adjustable firearm, which takes up as little space as possible and does not require any additional drive power and enables reliable supply of the cartridges in any position of the weapon.
  • the device for feeding cartridges with which this object is achieved is characterized in that that this cartridge feed channel is curved in a circular arc and the center of curvature lies in the axis of elevation, that the tips of the cartridges located in this cartridge feed channel are directed against the elevation axis and the cartridge axes are radial to the elevation axis, that this cartridge feed channel is arranged approximately parallel to the swivel plane of the firearm during the elevation, - That an endless conveyor chain is arranged in this feed channel, with which the cartridges are transported to the cartridge entry opening of the firearm, and - That the conveyor chain can be expanded and contracted when the weapon is being raised, depending on the position of the firearm in the elevation plane.
  • the personnel for operating the firearm 11 are located partly in the armored hood 12 and partly in the container 13.
  • the armored turret 10 is rotatably mounted in a tank vehicle, not shown, in a manner known per se.
  • the cartridges 16 are arranged in cup chains 17 (see also FIGS. 4 and 5). With these cup chains 17, the cartridges can be conveyed out of the magazine 14 on the one hand and can be transported from the magazine 14 to the firearm 11 on the other hand.
  • the firearm 11 can be pivoted about an elevation axis 50. In Fig.1 three different positions of the weapon 11 are indicated.
  • the weapon 11 In a first position, the weapon 11 is arranged horizontally; in a second position the weapon is shown inclined by + 45 ° and in a third position by - 10 °. The supply of ammunition to the weapon 11 must be ensured in each of these positions and also in all intermediate positions.
  • the subject of the present invention is a cartridge feed device 15 which allows the feed of cartridges 16 at any inclination, i.e. Elevation of the firearm 11 enables, as described below.
  • the cartridge magazine 14 is divided into two halves 18 and 19.
  • the two conveyors 15 'and 15 ⁇ have an arcuate guide channel 20.
  • the center of curvature of this arcuate guide channel 20 coincides with the Elevation axis 50 together, such that in each position of the firearm 11, the cartridges 16 can be fed to the entry opening, not shown, of the firearm 11 in the guide channel 20 (see FIG. 1).
  • this guide channel 20 can be telescopically extended and shortened in such a way that the end of the guide channel 20 is in the region of the aforementioned entry opening of the weapon 11 in any position of the weapon 11.
  • the cup chain 17 located therein can be lengthened and shortened when the guide channel 20 is lengthened and shortened, it is designed accordingly, as will be explained below with reference to FIGS. 4 and 5.
  • the cup chain 17 is composed of a number of cups 21.
  • These cups 21 are of conventional design and are therefore not described in detail here.
  • Each cup 21 serves to hold a cartridge 16, as can be seen in particular from FIG.
  • the cups 21 are connected to one another via three tabs 22, 23 and 24 in the form of a knee joint. Of these three tabs 22-24, only two tabs 22 and 23 are visible in FIG. 4, since the third tab 24 is located behind the second tab 23 in this view.
  • the two tabs 23 and 24 are articulated on a cup 21 and the first tab 22 is articulated on the next cup 21 and forms a joint with the other two tabs 23 and 24.
  • the distance between adjacent cups 21 can be increased and decreased.
  • the maximum distance a can be reduced to the minimum distance b.
  • the tabs 22-24 are designed such that the cup chain 17 can be curved in different planes.
  • the cup chain 17 can be adapted to the arcuate curvature of the guide channel 20, as can be seen from FIG. 5.
  • the guide channel 20 consists of three groups A, B and C of rails that can be telescopically pushed into one another.
  • the first group A is composed of four outer guide rails 25-28 and two inner guide rails 29 and 30.
  • the second group B is also composed of four outer guide rails 31-34 and two inner guide rails 35 and 36.
  • the third group C is also composed of four outer guide rails 37-40 and two inner guide rails 41 and 42. 7 shows all eighteen rails 25 - 42 in section.
  • the twelve outer rails 25 - 28; 31-34 and 37-40 serve to guide the cartridges 16 and the six inner rails 29, 30; 35, 36; 41, 42 serve to guide two cup chains 17, of which only two cups 21 are shown in FIG.
  • Each of the three groups A, B and C of outer guide rails 25-28; 31-34 and 37-40 is able to guide cartridges 16.
  • two of the three groups A and B of inner guide rails 29, 30 and 35, 36 are able to guide the cups 21.
  • the two inner guide rails 41, 42 of the third group C according to FIG. 7 are unable to guide the cups 21.
  • a further inner guide rail 43 is required, which can guide the cups 21 with the guide channel 20 fully extended, see FIG. 6.
  • each cup 21 has four guide bolts 44-47, only the two bolts 44, 45 being visible in FIG. 4 and only the two bolts 44 and 46 being visible in FIG. 7, while the other two are in the current view are behind it.
  • the outer ends of the bolts 44-47 are guided and with the further inner guide rail 43, the inner ends of the bolts 44-47 are guided, as can be seen from FIG. 7 are located in Guide channel 20 two cup chains 17 side by side, one of which brings the cartridges 16 to the firearm 11, while the other returns the cartridges 16 to the cartridge magazine. At the upper end, these two cup chains 17 are connected to one another, as can be seen from FIG.
  • the upper end of the cartridge guide channel 20 is connected to the firearm and the lower end is connected to the stationary cartridge magazine, such that when the firearm 11 is pivoted about its elevation axis 50, the cartridge guide channel automatically shortens or lengthens, depending on whether the elevation angle is increased or is reduced.
  • the cup chain 17 at the upper end of the guide channel 20 is driven directly by the firearm 11, in synchronism with the cadence of the weapon 11.
  • the cup chain 17 is driven by a Booster motor 44, the booster motor 44 not having to rotate exactly in synchronism with the cadence of the firearm 11 due to the length of the cup chain 17.
  • the two booster motors 44 not only drive the two cup chains 17 on the right and left of the firearm 11, but also all the cartridges 16 which are located in both halves 18 and 19 of the cartridge magazine 14 of the container 13.
  • the cartridges 16 pass from the cartridge magazine 14 onto the cup chain 17 and from there into the firearm 11, as can be seen in particular from FIG.
  • the guide channel 20 can be shortened and lengthened during a series fire in accordance with the elevation of the firearm 11. If the weapon 11 is inclined downwards by an angle of -10 °, the guide channel 20 must be fully extended, see Fig. 1. However, it is Firearm 11 directed upwards by an angle of + 45 °, the guide channel 20 must be completely pushed into one another, since the cartridge entry opening of the firearm 11 is then in its lowest position. The distance a between the individual cups 21 of the cup chain 17 is then reduced to the distance b, see FIG. 4. The three groups A, B and C of guide rails 25-40 are completely pushed into one another at this maximum elevation, see FIG. 6, in which these three groups A, B and C of guide rails 25-40 are shown completely pulled apart. 3, the cup chain 17 moves upward on the inner side of the guide channel 20, as indicated by arrows. The cup chain 17 thus moves downward on the outer side of the guide channel 20. Cartridges 16 can be filled into the cartridge magazine 14 with this part of the cup chain 17 moving downward.
