Definitions

  • the invention relates to a lockable self-loading handgun, for example from the US 3,955,470 (Kruzell ) is known.
  • Such a weapon is from the DE 196 16 397 C2 (Guhring et al. ) known and has proven to be excellent, especially under difficult conditions, such as the sand-mud test according to NATO AC225.
  • Similar weapons are for example from the DE-PS 478 630 together with the associated master registration DE-PS 459 454 (both Kiraly ), DE 28 12 732 A (cedar ), U.S. PS 2,941,449 (Reed ), U.S. Patent 4,604,942 (Benelli ), U.S. Patent 3,318,192 (Miller ), U.S. Patent 3,955,470 (Kruzell ), known; also as assault rifles HK416, Steyr Aug, FN CAL and US rapid-fire rifle M16.
  • the invention aims to provide an alternative breech control, which is more closely adapted to the energy conditions in the weapon during the self-loading process and is easy to manufacture.
  • the division of the unlocking control edge into three different, mutually merging edge sections, each with an increasing angle of inclination with respect to the longitudinal direction, serves to optimize the unlocking function of the locking head controlled by the control link via the control bolt.
  • the control link of the backward moving lock carrier hits the longitudinally stationary control bolt of the lock head with its first unlocking edge section with a very flat slope.
  • This first unlocking edge section serves as a lift slope for releasing and for the first movement of the closure head, which is under pressure.
  • the adjoining second unlocking edge section accelerates the rotary movement of the locking head in the direction of its unlocked position via the control bolt.
  • This is also known per se from the two aforementioned German Kiraly patents.
  • the finally third unlocking edge section additionally and continuously accelerates the rotary movement of the closure head into its final unlocked position.
  • the control bolt, and with it the locking head remains in its unlocked position. He now takes part in the return movement of the closure carrier. He loosens the cartridge case that has been deflated in the cartridge chamber and pulls it out. The following has emerged in the case of attempts to fire: after the cartridge has been fired and the cartridge case has been loosened in and its pulling out of the cartridge chamber, there is still a residual gas pressure in the cartridge chamber and tube that is not harmful to safety. This residual gas pressure also accelerates the cartridge case, which has been deflated in the cartridge chamber, and the already retracting locking head with control bolts.
  • the locking head would even overtake the locking carrier moving backwards, if it were not for the control bolt on the control link.
  • This phenomenon is used in that the longitudinal diameter of the sixth edge section is somewhat larger than the diameter of the control bolt. Therefore, the control pin carried backwards by the control link initially has a small one Distance from the right, that is, in the rearward direction, lower part of the sixth section of the curve and, owing to the aforementioned additional acceleration, imprints this on an impulse which in turn accelerates the return movement of the entire closure carrier. At the same time, this pulse is imprinted - somewhat in accordance with the increase in the longitudinal diameter - which has proven very useful in attempts at bombardment. The closure carrier and the closure head thus accelerate onto the closing spring, from which they are finally brought to the style and are then accelerated forward again.
  • the breech head comes to a standstill shortly before the cartridge chamber - but not the breech block. Whose front, at the transition from the sixth to the fourth edge section z. B. rounded edge now lifts the control pin strongly. The locking rotation of the breech head begins and is slowed down to the end by the fourth edge portion and further by the fifth locking edge portion.
  • the radius of curvature of the part of the circular-arc-like sixth edge section adjoining the third unlocking edge section and / or the part of the circular-arc-like sixth edge section corresponding to the radius of the control bolt corresponds (cf. claim 2). This measure ensures a good retention of the control pin in its fully unlocked position during the reverse and subsequent forward movement of the lock carrier; likewise a good transmission of the backward pulse exerted by the residual tube pressure from the deflated cartridge case to the closure head together with the control bolt and finally - via the rear end of the sixth edge section - onto the closure carrier.
  • the difference between the elongated longitudinal diameter of the sixth edge section and the diameter of the control bolt is preferably in the range from 0.2 mm to 1 mm, particularly preferably between 0.3 mm and 0.8 mm, in particular in the range from 0.4 mm to 0 , 6mm (see claim 3).
  • the weapon geometry and the ammunition used e.g. Cal. 5.56 x 45 NATO, in particular to consider the propellant charge.
  • a substantially U-shaped seventh edge section preferably connects the beginning of the first unlocking edge section with the end of the fifth locking edge section (cf. claim 4). This measure ensures a secure fit of the control pin in the locked position of the locking head. At the same time, it ensures that the unlocking rotation of the locking head begins with a delay depending on the length of the U-legs, i.e. when the gas pressure in the pipe has already dropped sufficiently. In addition, this allows the lock carrier to pick up speed before its control link begins to pivot the control pin u.
  • the distance between the mutually parallel unlocking and locking edge sections and between the two U-legs corresponds to the diameter of the control pin, preferably a few hundredths of a millimeter larger than this diameter (cf. claim 5).
  • control link is preferably selected so that it allows a longitudinal displacement of the locking member relative to the control pin of 9mm to 17mm, preferably 11mm to 15mm, in particular 12mm to 14mm (see claim 6).
  • U-leg of the seventh edge section which adjoins the beginning of the first unlocking edge section and is longer than the parallel U-leg adjoining the end of the fifth locking edge section (cf. claim 8). This further delays the start of the unlocking rotation of the locking head, i.e. unlocked at even lower pressure.
  • the control link is preferably arranged laterally opposite the cartridge ejection window in such a way that its unlocking edge is above, i.e. lies above the locking edge (cf. claim 11). This measure serves to counter any dirt that is adhering to the unlocking edge. Because of gravity, it falls down more easily.
  • Designing the weapon as a gas pressure loader has the advantage that further control measures can be carried out via an adjustable gas take-off on the tube, in particular after a possible exchange of the tube and the associated change in caliber and propellant charge.
  • the Figures 1 to 4b each schematically show the breech system or parts thereof of a rapid-fire rifle designed here as a gas pressure loader.
  • the tube 2 with its selenium axis designated as the longitudinal direction 4, has a cartridge chamber 6 at its rear end and is fixed in a rotationally fixed manner in a locking sleeve 8, which in turn is rigidly mounted in the weapon housing (not shown).
  • the rear end of the locking sleeve 8 has a round opening 10, from which radially arranged radial grooves 12 extend, each of which has an approximately rectangular cross section.
  • a round chamber 16 is formed between the front edge 14 of this opening and the rear end of the tube 2, the inside diameter of which corresponds approximately to the diameter that the groove bottoms of the round opening 10 form.
  • the closure has a closure carrier 18 and a closure head 20 mounted therein for longitudinal displacement and rotation.
  • the closure head 20 has at its front end a cross section complementary to the round opening 10 of the locking sleeve 8 with projections or locking lugs 22, the geometry of which corresponds to that of the radial grooves 12; and a length that corresponds to the length of the chamber 16.
  • the closure head 20 can be inserted through the round opening 10 into the round chamber 16 in a rotational angle position aligned with the round opening 10.
  • This angular position of the locking head corresponds to its fully unlocked position. From this position, the closure head 20 is rotated into its locked rotational position when the closure carrier 18 continues to advance and is completely unlocked again after a cartridge has been fired.
  • the locking head 20 must maintain its unlocked rotational angle position during its subsequent return movement together with the closure carrier 18 and, in turn, subsequent forward movement until it has again run forward through the round opening 10.
  • closure head 20 If the closure head 20 is then rotated again in this position, its locking lugs 22 engage behind the webs, also called counter-warts, between the radial grooves 12 of the locking sleeve 8, while the locking head 20 simultaneously sits or almost sits on the rear end of the tube 2. Now the closure head 20 can no longer be moved in a straight line in the longitudinal direction 4 of the tube 2; it is "locked”. Is it turned back to its previous position, i.e. "unlocked”, then it can be pulled back out of the round chamber 16.
  • the closure part 20 is guided with its rear part in the closure carrier 18.
  • the closure carrier 18 is by means of a gas piston device (not shown) ( FIG. 3 only shows a gas take-off device 34 on the tube 2) when firing backwards in the direction of arrow 32 against a closing spring (not shown) and then forced back into the lead by the latter.
  • FIG. 4b also shows a cartridge extractor 28 together with cartridge ejector 30.
  • a control bolt 36 attached to the rear part of the closure head 20 passes through a control link 40 designed as an elongated hole in a wall of the closure carrier 18.
  • Fig. 5 shows schematically the contour of the control link 40 is on an enlarged scale.
  • the closure carrier 18 When the locking head 20 is locked ( Fig. 1 ) or is in a locked position ( Fig. 4a and 6 ), then the closure carrier 18 is in its foremost position and is at the rear end of the tube 2. The control pin 36 is therefore shortly before the rear end of the U-shaped seventh edge section 80.
  • the breech carrier 18 When firing, the breech carrier 18 is in the direction of arrow 32 in Fig. 2 moves, and slides in with his Fig. 5 illustrated legs and edge portions 82, 52, 54 and 56 over the control pin 36. Since the locking head 20 is locked, it remains stationary in the longitudinal direction; likewise the control bolt 36 rigidly connected to it.
  • the locking head 20 is rotatably supported in the locking carrier 18, with the result that the unlocking control edge holds it 50 first with the help of its first edge section 52, then its second edge section 54 and finally its third edge section 56 increasingly pushes downward and turns it counterclockwise - viewed from behind - increasingly faster into the unlocked position.
  • the control bolt 36 After leaving the third unlocking edge section 56, the control bolt 36 remains in the sixth edge section 70.
  • its locking lugs 22 are aligned with the radial grooves 12 of the locking sleeve 8.
  • control pin 36 bears against the rear section of the sixth edge section 70 during this forward movement. This advance continues until the closure head 20 lies against the rear end of the tube 2. As soon as he and with him the control pin 36 have become longitudinally stationary, the control pin 36 is rotated into the locked position by the locking edge 60, more precisely by its fourth and fifth edge sections 62 and 64 - that is to say seen clockwise from the rear. It is now back in the Figures 1 and 6 locked position shown.
  • the empty cartridge case is ejected when the breech head 20 returns and a new cartridge is fed in during its course in a manner known per se.
  • the fully unlocked rotational position of the breech head 20 can be additionally secured during its common return and advance with the breech carrier 18 by reaching under the control bolt 36 under a guide rail 90 fastened in the weapon housing (see Fig. 12 ).
  • the rear edge portion 80 of the control link 40 has a U-shape and receives the control pin 36 in its locked pivot position. With its two legs running in the longitudinal direction 4, it merges into the first unlocking edge section 52 and the fifth locking edge section 64. The length of these two U-legs determines the distance D1 which the breech carrier 18 initially runs back after the shot and thereby absorbs kinetic energy before its unlocking control edge 50 engages the control pin 36.
  • Fig. 5 it can also be seen that the breech carrier 18 and thus its control link 40 runs through a distance D2 with respect to the breechhead 20 for the complete rotation thereof into its unlocked or locked position, the length of which - depending on the weapon geometry and ammunition used, for example cal. 5.56 x 45 NATO, in particular propellant charge - preferably in the range from 9 mm to 17 mm, more preferably 11 mm to 15 mm, particularly preferably 12 mm to 14 mm, for example 13 mm.
  • the center point of the free end of the control pin 36 lying in the control link 40 passes through approximately the distance identified by the reference numbers 41, 42, 44, 46 and 49.
  • the section ⁇ d 49 serves for the already mentioned utilization of the residual tube pressure acting on the deflated cartridge.
  • the length of ⁇ d corresponds to the difference between the longitudinal diameter of the sixth edge section 70 and the diameter of the control bolt 36. It is preferably in the range of 0.2 mm and 1 mm , in particular of 0.3 mm and 0.8 mm, particularly preferably in the range of 0.4 mm and 0.6 mm, for example 0.5 mm.
  • the radii of curvature of the front and rear areas are true of the sixth edge section 70 is adapted to the radius of the control pin 36, but the additional distance ⁇ d 49 lengthens the longitudinal diameter of this edge section 70, ie it is larger than the diameter of the control pin 36.
  • the unlocking control edge 50 is composed of the first rectilinear edge section 52 with a relatively flat angle of inclination a to the longitudinal direction 4, the adjoining rectilinear second edge section 54, with a significantly steeper angle of inclination ⁇ to the longitudinal direction 4 and an adjoining curved third edge section 56, whose all tangents ⁇ i have a larger angle of inclination to the longitudinal direction 4 than the second edge section 54 with its angle of inclination ⁇ .
  • angles of inclination are preferably in the following ranges: angle of inclination a in the range from 16 ° to 32 °, preferably 20 ° to 28 °, particularly preferably 22 ° to 26 °, for example 24 °; Inclination angle ⁇ in the range from 30 ° to 45 °, preferably 34 ° to 41 °, particularly preferably 35 ° to 40 °, for example 38 °.
  • the third angles of inclination ⁇ i of the tangents on the curved sixth unlocking edge section 70 move in the range from 55 ° to 85 °, preferably 60 ° to 80 °.
  • the first edge section 52 with the angle of inclination a ensures a smooth entry of the control link 40 into its unlocking work and is significantly shorter than the second edge section 54. Its larger angle of inclination ⁇ accelerates the unlocking rotation of the locking head 36 until the third edge section 56 as a curved edge section for the control pin 36 again impresses with an additionally increasing rotational acceleration.
  • the control pin 36 In its fully unlocked position, the control pin 36 is located in the sixth edge section 70 and initially lies with its forward, i.e. in the longitudinal direction 4 directed to the peripheral section of the sixth edge section 70.
  • the two areas of the control bolt 36 and the edge section which abut one another have radii which correspond to one another.
  • the closure head 20 comes to a standstill in the round chamber 16 in front of the cartridge chamber 6.
  • the Figures 6 to 14 show the control link 40 of the lock carrier 18 and the control pin 36 in their different functional positions, during a cycle of the lock control.
  • Fig. 6 shows the control pin 36 in the locked position of the locking head 20 - as is known in the upper rear horizontal niche of the control link 40 of the lock carrier 18.
  • the control link 40 is located - as already mentioned in the introduction DE 196 16 397 C2 (Guhring et al. ) known - on the left vertical side of the closure carrier 18 facing away from the cartridge ejection window.
  • DE 196 16 397 C2 Guhring et al.
  • the first and the second edge sections 52, 54 of the unlocking control edge 50 run parallel to the respectively opposite fourth and fifth edge sections 62 and 64 of the locking control edge 60.
  • This also has manufacturing advantages, among other things, since the mutually parallel edges of the control link are lighter can be produced, that is to say differently inclined control edges, for example can be produced in a single milling operation.
  • the lower front edge section 70 of the control link 40 is provided as a longitudinally elongated, circularly rounded recess, the diameter of which in the longitudinal direction is somewhat larger than the diameter of the control pin 36.
  • Fig. 6 further show that there is a free gap 81 between the control bolt 36, which remains in its locked position, and the right end of the control link 40, that is to say the right end of its seventh edge section 80.
  • the control pin is not in the locked state on the lock carrier.
  • the first control slope i.e. the first unlocking edge section 52. Because of its flat incline, it serves as a lifter slope for loosening and for the first movement of the closure head 20 which is under pressure. Due to the gentle run-up of the first flat unlocking slope 52 on the control bolt, there is hardly any loss in speed of the returning closure carrier 18.
  • control link 40 is already in its backward movement as a result of the closure carrier 18 driven backwards by the gas piston after the shot.
  • Fig. 8 the closure carrier 18 is still on its return.
  • the second edge section 54 runs onto the periphery of the control pin 36 and again accelerates its rotational movement owing to the steeper inclination angle ⁇ . The unlocking rotation of the closure head 20 thus increases.
  • Fig. 9 shows the closure carrier 18 still on its return. Its third unlocking edge section 56 now runs over the periphery of the control pin 36 and, due to its greater curvature, presses the control pin 36 down even faster. The pivoting movement of the same and thus the unlocking rotation of the closure head 20 is accelerated again.
  • the control pin 36 After finally leaving the curved third unlocking edge portion 56 ( Fig. 10 ), the control pin 36 is in its unlocked state in the sixth edge section 70.
  • This edge section has a somewhat elliptical shape insofar as the radii of curvature of its front and rear sections each correspond to the radius of the control pin 36, but its longitudinal diameter is longer by the distance ⁇ d than the control pin diameter.
  • the control pin 36 Due to the use of the residual pressure energy in the tube 2 already described, the control pin 36 now strikes the rear section of the sixth edge section 70 and accelerates it again (see here Fig. 11 ).
  • the resulting additional speed increase for the closure carrier 18 can be up to 1 m per second and more, depending on the residual gas pressure in the pipe 2, that is to say depending on the location of the gas pressure-reducing device 34 on the pipe 2 and the caliber used, in particular propellant charge.
  • control pin 36 In order to ensure the complete movement of the control pin 36 into its lowermost position (unlocking position) in the control link 40 in the event of shooting under difficult conditions (eg sand / mud tests according to NATO AC225) even if dirt has entered the control link and elsewhere, are they in the Figures 10, 11 and 15 Embodiments of the control pin 36 and the sixth edge section 70 shown.
  • the control pin 36 has a recess 37 in its peripheral sections respectively opposite the front and / or the rear edge section of the sixth edge section 70, so that only the shaded area of the control pin 36 remains. Additionally or alternatively, the sixth edge section 70 is curved elliptically in the longitudinal direction 4.
  • the resulting free spaces serve as a dirt reservoir for any residues of contamination that may be in the control link or can no longer be removed quickly enough.
  • any dirt residues With the further movement of the control link 40 in relation to the control pin 36, any dirt residues are usually released automatically. With appropriate accumulation, especially before the first shot, they can lead to high friction losses and malfunctions.
  • the returning breech After pulling out and ejecting the shot sleeve, the returning breech reaches its rearmost position in the housing, after which the closing spring (not shown), which is tensioned in the return, reverses and drives it forward in the direction of the cartridge chamber 6.
  • control pin 36 In this position of the locking head 20, the control pin 36 has already run in front of the guide rail 90 in the longitudinal direction 4 and is then moved by the edges 62 and 64 of the locking control edge 60 of the locking carrier which continues to advance 18 pivoted into its locking position, like that 13 and 14 demonstrate.
  • Fig. 15 shows an embodiment of a control pin 36 with the bore 24 for the firing pin 26 and recesses 37 to provide a space for dirt that has penetrated into the control link 40.
  • the section of the control pin 36 shown with reference number 35 protrudes from the control link 40.
  • the peripheral firing pin upper side 38 and the opposite peripheral firing pin lower side are guided by the control edges of the control link 40.
