Definitions

  • the invention relates to a locked handgun with a closure from a closure head and a Closure carrier, according to the preamble of claim 1.
  • Forward here means the direction that pointing to the muzzle of the weapon.
  • connection arrangement between the closure head and the forms a neck that for example, is rigidly connected to the closure head and telescopic into the fastener carrier by the length of the Locking section can be inserted when the closure is locked.
  • a neck can also on Closure carrier formed and in the closure head can be inserted, or can be of a separate part be formed, both in the breech head and in the closure carrier is insertable.
  • the locking piece is arranged to run and stationary is so when the closure is locked by the closure head attacked that of a fired cartridge at least the recoil exerted by the closure head does not moved back instantly and significantly.
  • the engagement between the locking head and locking piece can by means of radially extendable rollers, radially extendable Blocks or flaps or the like. nowadays is usually locked by turning the several locking lugs provided so that the locking lugs are stationary in the locking piece reach behind trained warts.
  • the release can be done with a recoil loader Backward movement of the barrel and the entire breech be effected over an initial distance, so that the Closure carrier is set in motion and then the Locking head twisted, the loading movement is carried out etc. But it is particularly easy to use a gas piston the launch gases removed from the barrel, in turn sets the fastener carrier in motion.
  • the locking device is constructed so that the Breech head very much when fired can perform slight backward movement, then this can Backward movement through a translation mechanism the closure carrier are applied, which in turn takes the breech head (such as the G 3 rifle).
  • the full rear moving shutter moves forward and on a Cartridge from a magazine or a de-belting device comes from behind with the breech head to this Push the cartridge into the barrel, then the breech head pressed against the closure carrier, so that the positive control seeks the locking movement of the Trigger head.
  • the Locking head in turn in guideways of the weapon housing guided so that this locking movement is prevented.
  • Breech head and guide thus move partly under strong mutual support sliding on each other, so that the wear increases and the reliability of the weapon is reduced.
  • sand through which the top cartridge in the magazine that counteracts with great force the magazine lip is pressed, sits even more tightly than common.
  • the impact of sand also makes it difficult Sliding engagement between the locking head and the guide is essential.
  • the invention is the Task based on the handgun mentioned at the beginning to further train that they are in functional safety is improved.
  • the only additional part is a spring plate sleeve required the fairly large dimensions has (the length corresponds at least to that Interlocking section) and each in the expanded state longitudinal force acting on the closure head, from this immediately and bypassing the forced control on the Lock carrier transmits.
  • the length section of the cuff that is in the annulus occurs corresponds approximately to the locking distance.
  • the cuff is an easy to manufacture, tallest uncomplicated component, its function during the loading process consists of expanding resiliently or slightly compressed against its spring action will. There is no intervention in pegs or the like. A There is no wear and tear. Since the travel of the Cuff is low, does not have to break with the Cuff.
  • the cuff can be removed and installed simply by Sliding on the connection arrangement with disassembled Closure.
  • the cuff is also made of relatively thick sheet metal educated. Its corrosion therefore does not affect the flawless effect, since the corrosion is only a small one Fraction of the material thickness concerns.
  • the cuff also protects her hidden parts of the connection arrangement Splashes of dirt.
  • the component or assembly that with "Connection arrangement” is or are, is the Arrangement that in the unlocked state of the closure Lock head and the lock carrier at least around the locking distance keeps spaced and their mutual Approach permitted in the locked state.
  • connection arrangement can be in the closure head and / or be insertable into the closure carrier.
  • the Connection arrangement can also extend in itself or shorten, e.g. in the form of a knee joint mechanism.
  • the lock carrier can be locked immediately sit on the breech head. In this case, he points in unlocked position a distance from the closure head, which corresponds to the locking distance.
  • the axial The length of the cuff is then advantageously correct also corresponds to the length of the locking section.
  • connection arrangement is like this trained that a distance already in the locked state between the breech head and the breech carrier, which then unlocks around the locking distance extended.
  • the cuff can be conveniently in their Length should be such that it is in the unlocked state entire distance between the closure head and the Locking straps bridged so that when Axial forces the connection arrangement always largely remains force-free (claim 3).
  • the rotary lock is one of the possible locking methods preferred, in which the closure head around elongated core axis of the barrel is rotatable.
  • the cuff preferably loosely surrounds the Connection arrangement (claim 4).
  • the advantage of the rotary lock is that with simple Averaging largely on the soul axis symmetrical support of the closure can be effected can, so that when shooting at the barrel not one-sided Impact loads that include the Can affect shooting performance.
  • Locking lugs the webs of the locking piece.
  • two are classic opposite locking lugs in a radial plane, if necessary at least one further locking lug in another radial plane.
  • the wall of the Cone for compressing the sleeve of longitudinal grooves is cut off, the exemptions for running in Form locking lugs (claim 5).
  • connection arrangement is preferred as a shaft-like Extension of the breech head arranged when Lock at least around the locking distance in the Closure carrier immersed (claim 6).
  • the shaft is already in the fastener carrier from the outset extend into it so that it only locks telescopically around the locking distance in the Pushes in the closure carrier.
  • the annular space is preferably in the closure carrier educated.
  • the cuff can form a guide element if when the lock is locked, on the one hand, from the inside rests against the cone under spring tension and on the other hand at least largely fills the annulus because then the closure carrier regardless of the closure head on the Cone and thus aligned to the soul axis of the barrel.
  • the locking lugs of the breech head form a front stop for the cuff.
  • the Closure carrier forms with its zone radially around the Annulus and outside the annulus a rear stop for the opened cuff.
  • the breech head has an extractor claw, the rear part preferably sits under the cuff (claim 7).
  • the cuff not only protects the rear part the extractor claw, but then supports it radially, if there is an arch movement under the Cartridge edge performs, so that the reliable hold of the Extractor claw on the cartridge bottom remains guaranteed.
  • the Cuff can even be the spring for the extractor claw form.
  • a closure head 1 in side view shown. This is made up of an overall cylindrical, elongated shaft 3 formed of a rear portion with a larger diameter and a front section with has a smaller diameter, between which a paragraph 17 is formed.
  • the rear section of the shaft 3 is with a transverse bore 15 for receiving a control pin (not shown).
  • the side surfaces of the locking lugs 5 are in Levels that extend parallel to levels that the Contain the longitudinal central axis 11 of the closure head 1.
  • the free edges of the locking lugs 5 are beveled.
  • the locking lugs 5 each have the same Angular distance to each other. One of these Locking warts 5 are missing. Extends through the gap an extractor claw 9.
  • the extractor claw 9 has a rear section, in a longitudinal groove in the front section of the shaft 3 sits and in the area between the two paragraphs 17, 19 largely flush with the outer surface of the shaft 3 completes.
  • the rear section of the extractor claw 9 is pivotable about a pivot pin 21 which passes through it transversely and which is embedded in the shaft 3.
  • Extractor spring Under the end of the extractor claw 9, which extends over the Swing pin 21 extends rearward, one in the shaft 3 embedded compression spring (not shown) as Extractor spring may be provided.
  • This spring can namely replaced by a resilient sleeve 13 (Fig. 1 b and 1 c) be, which is a circular cylinder made of spring sheet metal, the one has continuous longitudinal slot.
  • This longitudinal slot has in the relaxed state of the cuff 13 Slot width a on (Fig. 1 b).
  • the length of the cuff 13 is such that it is between the two paragraphs 17 and 19 fits.
  • the cuff 13 may prevent the Swivel pin 21 can fall out.
  • the inner wall of the cuff lies in a relaxed state 13 loosely above the rear section of the extractor claw 9.
  • the cuff 13 When assembled, the cuff 13 can be easily over the rear section of the shaft 3 are pushed.
  • the rear section of the shaft 3 with a larger diameter extends forward with little play open hole in a closure carrier 23, the one side is penetrated by an elongated hole forming a backdrop 27, that extends obliquely to the longitudinal direction and its Width corresponds to the final diameter of a control pin, who sits in the transverse bore 15.
  • a locking piece 35 trained to the rear end towards the rear and outwards, forming a cone 31 expanded. Between the cone 31 and the cartridge chamber 29 an inner annular groove 37 is formed. Their axial width corresponds at least to the axial length of the Locking lugs 5.
  • the cone has longitudinal grooves 33, the number, arrangement and training of the locking warts 5 on the locking head 1 corresponds.
  • the cuff 13 now ensures that the closure head 1 only then relative to the closure carrier 23 in Can move longitudinally and thus twist if he is in the foremost position (Fig. 2 a and 2 b).
  • the closure carrier 23 is in its movement in (not shown) gun housing so that it is not can rotate the longitudinal central axis 11. If he is relative to Locking head 1 by the locking distance b to the rear is offset, then the rear paragraph 17 of the Locking head 1 in a position in which it is flush with the front end face of a cylindrical connecting piece 25 completes or protrudes something below it, by which the Closure carrier 23 is extended to the front. If the Locking head 1 completely released from the locking piece 35 is then the cuff 13 is exposed and can spring apart (Fig. 1 b). She takes one Outer diameter that is larger than that Outside diameter of the rear section of the Closure head 1 and thus the hole in the closure carrier 23 and covers part of the front face of the Nozzle 25
  • Fig. 1a shows the extractor claw 9 with respect to Longitudinal central axis 11 opposite a projecting tooth 40, the forms a "counterholder" for the cartridge case.
