Definitions

• Bushmaster foreign-powered machine gun has as a function control or drive to move the shutter and the ammunition feed a revolving chain, which gives her the name Chain Gun. Necessary downtimes are realized by guiding the chain (US 4,418,607, US 4,481,858, US 4,563,936, US 4,665,793, DE 30 21 200 C).
• DE 1 428 652 C also describes a loading device which has an endless pull chain which runs in a loop over sprockets.
• a pivotable carrier is proposed.
• the function control comprises two oppositely rotatable control rollers, each with a circumferential control groove (curve) for the axial reciprocation of the closure body.
• the control rollers are located in the rear of the pipe. Such an arrangement of the control roller is also described in DE 36 27 360 C1.
• a loading device for an automatic cross-closure tubular weapon is known from DE 31 18 383 A1.
• This charging device also comprises a control roller rotatably arranged in a feeder housing about an axis.
• a rigid locked Geradzugver gleich for a foreign-powered machine gun is published with DE 36 27 361 C1.
• a control roller is also proposed here.
• a cam drum has, operated by external drive, is used for linear movement of a straight pull closure.
• the cam drum accordingly has a circumferentially endless control cam. Furthermore, a short radially acting control cam and a longer axially acting control cam are arranged on the circumference.
• control roller is integrated in the plane of the tube axis soul.
• the control roller has a control body carrying at least two control cams.
• the curve information is converted into a rectilinear feed of the shutter. This solution is used especially for gas pressure boosters.
• the invention sets itself the task of demonstrating a simple function control, which also allows a small-scale weapons / machine gun.
• the invention is based on the idea to move away from known control drums or rollers to a control curve used in the function control in the vertical plane. This can then be incorporated, for example, below the shutter feed.
• a control link used for function control is incorporated in the vertical plane parallel to the path of a closure of the closure weapon which is to be guided in a straight line, which cooperates functionally with a drive link, likewise lying in the vertical plane, for guiding a means connected to the closure.
• the drive link is integrated in a movable slide, which in turn is adjusted by a universal design drive.
• a locking link is provided, which is preferably integrated together with the drive link in the movable slide. In this locking link, a bolt of a preferably weapon side arranged locking ring engage. This bolt in turn then moves the locking ring accordingly.
• the control link is weapons firmly integrated, the drive link and the locking linkage by means of slide back and forward run movably held.
• a connecting rod or the like is forcibly guided through the scenes and the slide along these scenes. With this connecting rod, the shutter is moved back and forth.
• the closure ring With the separate locking link, the closure ring can be rotated around the closure during the supply of the closure, whereby it is locked or unlocked. Warts are preferably attached to the locking ring, which in turn grip around warts on the closure and engage behind.
• Warts are preferably attached to the locking ring, which in turn grip around warts on the closure and engage behind.
• Such a rotatable closure is known for example from the applicant's own unpublished DE 10 2005 037 131.0.
• control link in a split rail and thus make them multi-part, preferably in two parts.
• This construction allows the consideration of the return paths of the weapon with the closure.
• the two-part rail preferably overlaps centrally and is held in this area against each other displaceable with a definable game.
• the drive of the connecting rod is effected by the slide, which is moved for example by means of a circulating chain, wherein other types of drive, such as connecting rods, motor etc. are alternatively also possible.
• This variability of the drive forms makes the novel guide system universally applicable and combinable.
• FIG. 2 is a view in view A-A of Fig. 1,
• Fig. 1, 3-6 a is a plan view of the individual positions.
• Fig. 1 to 6 is shown schematically a weapon 1 with the essential details for explaining the invention.
• a closure 2 Shown are a closure 2, a locking ring 3 and indicated a weapon barrel 4.
• the cover 2 for rectilinear feeding an ammunition / cartridge 5 travels within the weapon 1, a control link 11 a function control 10 is arranged, each in Top views in Fig. A is shown (to be carried out).
• the control link 11 has a shape comparable to a large S, with the central guide zone of the link 11 being stretched to the slightly curved curve ends (J).
• control link 11 is formed by a split rail 8.
• a circulating chain is indicated in this embodiment.
• This drive 6 interacts functionally with a sliding slide 7 incorporated on the closure side.
• a drive cam 12 which, in addition to the weapon side (8) integrated control link 11, part of the function control 10 is.
• the drive curve 12, starting with a short straight line, has a slightly s-shaped rise 12.1 in the front region, which subsequently loses again in a straight line 12.2.
• a connected to the shutter 2 connecting rod 14 engages within the drive cam 12 (also called connecting rod thrust curve) and the control link 11 a.
• a preferably likewise integrated in the slider 7 locking slot 13 is used to lock / unlock the shutter 2 in the use of the weapon 1 (will be explained).
• the slide 7 has a vertical plane, preferably slightly hired surface 7.1, in which the locking cam 13 is integrated so that a bolt attached to the locking ring 3 3.1 can engage in this slot 13.
• FIG. 2 shows a visual representation of the closure system in view A-A from FIG. 1. In this case, the side face 7.1 can be seen more clearly.
• the connecting rod 14 is in the so-called initial position A (Fig. 1) in the VerMedicbeladeposition 20 of the gate 11. Parallel to the connecting rod 14 is located at the straight beginning of the drive link 12. The cartridge 5 can in this position in the closure 2 are laid.
• the slider 7 is then moved, the connecting rod 14 is guided out of the shutter loading position 20, wherein the connecting rod 14 is transferred to the elongated guide zone of the control link 11 and the rising curve 12.1 of the drive link 12.
• the connecting rod 14 is displaced along the control link 11 by the slide 7 and thus the closure 2 with cartridge 5 is brought into the so-called feed position (position) 21 (FIGS. 3, 3a).
• the connecting rod 14 With a further adjustment of the slide 7, the connecting rod 14 at the slightly curved end of the control cam 11, the locking and firing position (parking position) 22, while the connecting rod 14 passes in this phase of the increase in 12.1 12.2 of the drive cam 12.
• the bolt 3.1 located on the locking ring 3 begins by being guided within the slot 13 with the locking by turning the locking ring 3 when the bolt 3.1 passes through the corresponding curve in the slot 13 (FIGS. 4, 4a).
• the connecting rod 14 itself is still in a so-called Parkposi- tion 22 together with the shutter 2 and is itself no longer moved, only the slide 7, wherein the drive link 12 further slides over the connecting rod 14 to drain the locking link 13.
• Fig. 5 the system takes the so-called weft release position.
• the shutter 2 is locked by the locking ring 3, the shot trigger is initiated, the drive 6 continues to run and moves the slider 7 further while the connecting rod 14 remains in the parked position of the control link 11 and slides within the Antriebskulisse 12 of the slide 7.
• the bolt 3.1 of the locking ring 3 also slides further within the locking cam 13, without in turn to adjust the ring 3.
• the slide 7 is now guided in the opposite direction by the continuously running drive 6, the steps described above are carried out in the reverse order.
• the shutter 2 is released (unlocked) by turning the locking ring 3 in the opposite direction, the connecting rod 14 is brought from the parking position and the shutter 2 is returned to the starting position.
• the solution provides to integrate in the rail 8 with the control link 11, a so-called backlash R.
• This game R takes into account the return path of the gun barrel 4 with closure 2.
