Definitions

  • the present invention relates to a housing for a firearm for receiving therein a longitudinally displaceably mounted closure carrier, which has a nose for the attack of a Re- petiergestShes, wherein housing and lock carrier are made of different materials.
  • the invention further relates to a firearm with such a housing.
  • the pressure of the powder gas generated when a shot is fired is often used to open the closure and the closure carrier during the repeating process.
  • the powder gases are recycled directly from a Laufanzapfung to the closure carrier.
  • the resulting heavy contamination of the closure carrier by Pulverschmauch often leads to malfunction.
  • it is of other types, e.g. from the assault rifle Steyr AUG, known to impart the necessary movement impulse with the pistons driven by the powder gases via the repeating linkage and the nose.
  • the contamination of the closure carrier is largely avoided.
  • the object is achieved according to a first aspect of the invention with a housing of the aforementioned type, which is characterized in that the side facing away from the nose of the inner surface of the housing is equipped with a sliding block of a different material from the housing material.
  • Such a sliding block absorbs the pulse-shaped torque in the housing and thus counteracts the wear and consequently the tilting of the closure carrier in the housing.
  • the material of the sliding block can - regardless of the housing material - be chosen so that arise in conjunction with the closure carrier material particularly favorable sliding properties.
  • the housing material is thereby freely selectable, so that even materials which have hardly or never been used up to now, e.g. Plastics or other metals or metal alloys, can be considered.
  • the housing made of aluminum and the sliding block are made of steel. It is particularly favorable if the sliding block is made of hardened steel, preferably of hardened steel provided with a sliding coating. This leads to particularly favorable sliding properties and increases the durability of the sliding block. Furthermore, this can achieve almost or even completely lubricant-free operation of the firearm.
  • the sliding block is in the region of the rear end of the housing. This leads to a point of torque introduction into the housing as far as possible from the point of action of the repeating linkage on the nose and thus to the smallest possible force acting on the housing, which reduces the load in the housing and increases the durability of the sliding block.
  • the sliding block is used interchangeably in the inner surface. So you can choose different Slide blocks, eg of different material or with different coating, used Vierden. Also, the exchange of a worn or damaged sliding block, for example, by frequent heavy load, simply possible.
  • the invention provides a firearm having a housing having the aforesaid features and a latch carrier received therein which has a tab for engaging a firing gun repeater linkage and slides on its side facing away from the nose on the slider block.
  • FIG. 1 shows a housing according to the invention for inserting a closure carrier with closure in a perspective view from above.
  • FIG. 2 shows the housing of FIG. 1 with inserted parts as well as a section of a detail in a longitudinal section
  • FIG. 3 the housing of FIG. 2 in a cross section along the section line A-A (FIG. 3) and B-B (FIG. 4) of FIG. Second
  • a housing 1 for a firearm e.g. a handgun, such as a semi-automatic or automatic rifle shown.
  • a closure support 2 and a closure 3 are accommodated therein.
  • the housing 1 is further the rear end of a (not shown here) barrel 4 is inserted, which can be coupled by means of a bayonet coupling 5 with the shutter 3.
  • a movable in the shutter 3 firing pin 6 is directed to a molded in the rear end of the barrel 4 cartridge chamber 7.
  • the firing pin 6 is in a conventional manner via a trigger mechanism (not shown) operable to its cultivation and attack on the firing pin 6, a housing 1 and the bolt carrier 2 from below passing through the shaft. 8 is provided. Fresh cartridges can be supplied via a further, the housing 1 also passing through from below the magazine shaft 9.
  • the housing 1 could extend around the barrel 4 in the direction of its mouth. Also, the barrel 4 could be bolted to the housing 1 or fixed in some other way and / or the trigger mechanism on the housing 1 to be firmly attached.
  • closure carrier 2, closure 3 and barrel 4 are made of steel in the present exemplary embodiment.
  • the housing 1 itself is made of aluminum to reduce the weight of the firearm.
  • the housing 1 and the closure carrier 2 could also be made of other material combinations, e.g. with plastics and / or other metals or metal alloys.
  • the housing 1 is provided with four slide rails 10, one or more of which are e.g. to form the shafts 8, 9 may also be interrupted in sections, as shown in one of the slide rails 10.
  • the slide rails 10 may be removable from the housing 1, e.g. inserted in dovetail grooves, so that they can be easily replaced in case of heavy wear or damage or to adapt to a new lock carrier 2.
  • the slide rails 10 may be permanently inserted into the inner surface of the housing 1, e.g. glued in, welded in, pressed in or the like.
  • the slide rails 10 are distributed around the circumference of the inner surface 11 around the lock carrier 2 and extend in the longitudinal direction of the lock carrier 2, so that the lock carrier 2 on the slide rails 10 and not on the inner surface 11 of Housing 1 slides.
  • the sides of the slide rails 10 facing the closure carrier 2 may be convex, concave or flat in cross section, so that slide rails 10 and closure carriers 2 are in line or planar contact with one another.
  • longitudinal webs for resting on the slide rails 10 could also be formed on the closure carrier 2 (not shown).
  • the slide rails 10 are made of a material different from the material of the housing 1.
  • the slide rails 10 are made of steel.
  • the steel of the slide rails 10 can be hardened.
  • the slide rails 10 could be made of special, for example, sintered materials.
  • the slide rails 10 may additionally be provided with a sliding coating.
  • the closure carrier 2 also has a nose 12 for the engagement of a linkage 13 for repeating the closure carrier 2 or closure 3.
  • the repeating linkage 13 can be driven in a manner known per se by one of the explosion gases during the firing Pistons ("gas drive", not shown here) or in any other suitable manner, eg by hand, the repeating linkage 13 pushes the bolt carrier 2 on his nose 12, and the bolt carrier 2 slides on the slide rails 10 in the housing first in the direction of 14.
  • a guide pin 15 of the closure 3 (FIG.
  • a sliding block 17 is arranged on the side of the inner surface 11 of the housing 1 facing away from the nose 12.
  • the slide block 17 is in the region of the rear end of the housing 1. Since the pulse of the RepetiergestShes 13 only acts on a part of the displacement path of the closure carrier 2, it is e.g. sufficient if the closure carrier 2 is slidably supported on the sliding block 17 only with a correspondingly short, preferably behind the shaft 8 bearing surface 18.
  • the sliding block 17 thus supports the slide rails 10 during the sliding movement of the closure carrier 2 during the action of the repeating rod 13 on the nose 12.
  • the sliding block 17 is - like the slide rails 10 - made of a different material from the housing material, in the present embodiment in coordination with the steel lock carrier 2 also made of steel.
  • the steel of the sliding block 17 can be hardened.
  • the sliding block 17 could be made of special, for example, sintered materials.
  • the sliding block 17 may be additionally provided with a sliding coating.
  • the sliding block 17 may be attached to the housing 1 e.g. be exchangeably mounted by means of a countersunk screw 19, so that it can be easily replaced in case of heavy wear or damage or for adaptation to a new lock carrier 2.
  • the sliding block 17 can be anchored in the housing 1 inextricably, eg glued, welded, pressed od. like.
