Definitions

  • the present invention relates to a hand guard assembly for a weapon, in which one or more (usually two) shell elements are fixed in a holder, so that the handguard shells surround a running section.
  • the holder has a spring-loaded holding unit, which receives and fixes the shell element (s) at one end.
  • the holding unit can be brought against a spring force in a release position in which it releases the corresponding end of the shell element, so that it can be removed radially to the run or vice versa. It also relates to a corresponding barrel arrangement and weapon.
  • Direction information such as front, back, top, bottom, right and left are given from the perspective of the shooter for a weapon held in the stop.
  • Such hand protection arrangements with removable handguard shells make it possible, in particular in so-called gas pressure loaders, to make the throttle linkage or a gas line, which is led into the weapon housing by a mouth-side gas take-off, by removing the handguard shells.
  • Such handguard arrangements are used, for example, in the M16 weapon family.
  • the object of the present invention is to provide an improved hand guard assembly.
  • the hand protection arrangement which is usually arranged in the region of the interface between barrel and housing, designed so that it can be mounted in the mounted barrel, in particular from the mouth side, can be fixed at the intended location and can be removed in the reverse direction.
  • This special embodiment of the holding unit makes it possible to replace the handguard assembly with shells completely against a component carrier with mounting rails, which can be fixed in other ways to the weapon.
  • the flexibility of the weapon is increased, and the replacement can be made without the weapon must be disassembled, especially without the barrel must be removed from the housing. This is particularly desirable when a part of the sighting device is arranged on the barrel itself, which would have to be re-established during disassembly / assembly of the barrel under certain circumstances.
  • the development according to claim 2 relates to a design of the holding unit, in which the mouth-side mounting is also suitable for a weapon or a barrel with mounted gas removal and / or sighting device.
  • the holding unit must be designed so that it can be pushed completely or disassembled on the gas take-off and sighting.
  • the spring-loaded holding unit has a retaining sleeve surrounding the barrel, a retaining sleeve surrounding the barrel. ter position to run fixable coupling element and a spring arrangement, which acts axially in the direction of the axis of the soul (barrel axis) between the retaining sleeve and coupling element (claim 3).
  • the functions: attachment of the spring-loaded holding unit to the weapon and fixation of the shell element can be decoupled.
  • the retaining unit Due to the action of the spring arrangement in the axial direction, the retaining unit can be brought into its release position by a directed against the spring force movement of the retaining sleeve.
  • the clasp-shaped design of the coupling element according to claim 4 makes it possible in a particularly simple way to frictionally couple this with a complementary formed mounting portion, which is fixed with respect to the barrel.
  • the holding unit is completely placed on the run or made removable from this. This avoids complex individual assembly to the weapon.
  • the frictional connection can be reinforced according to claim 6 by the use of the radial inherent elasticity of the coupling element.
  • the ö Samuelpanel opening serves as a passage for the gas rod or the gas piping.
  • the frictional coupling is made via a frictional engagement between a cylindrical inner surface of the coupling portion and a cylindrical outer surface of the mounting portion.
  • the mounting section is arranged either directly on the barrel, on a running nut fixing the barrel in the housing or on a housing component.
  • the design of the spring assembly according to claim 9 facilitates in comparison to the barrel concentrically surrounding springs (eg corrugated springs, disc springs) on the one hand, the formation of the passage for the gas pressure loading mechanism (throttle linkage, gas piping) and allows for another eccentric actuation of the retaining sleeve, so that when arranged several handguard shells can each be removed or used individually, without loosening the other during assembly or disassembly.
  • the embodiments according to claims 10-12 relate to a second holding unit which receives each of the second end of the shell elements in a defined circumferential direction to run.
  • a repeatable assembly and disassembly of the shell elements in a defined circumferential direction to the run is possible (claim 10).
  • this second holding unit Due to the likewise clasp-shaped design of this second holding unit, it is possible to set them up either radially or axially to run or remove. This facilitates the arrangement on the housing side of a fixed sight on the barrel or gas extraction (claim 11). Thus, the second retaining element can be attached or removed without further disassembly of the weapon.
  • the design of the second holding unit according to claim 12 defines this in the circumferential direction to the barrel and thus ensures the defined in the circumferential direction to the barrel position of the shell member safely.
  • the holding units include the ends of the handguard shell cuff-shaped and set at least one end in the axial direction, the handguard shell is defined in the axial direction defined to run.
  • the interaction of a frusto-conical outer surface at one end of the shell member with one of the holding units according to claim 14 allows the shell member determined by the wedge effect thus caused radially and axially, so that it is largely free of play attached to the weapon.
  • Claims 15 and 16 each relate to a barrel assembly with a hand guard assembly according to the invention or a weapon with such a barrel assembly.
  • Show 1 shows the hand protection area of a weapon in a perspective view from above with cut-open holding units, wherein the barrel is not shown,
  • Fig. 2 is a side perspective view of a

  • other suitable measures to facilitate handling are provided (knurls, grip recesses, grip inserts, grip zones made of especially grippy materials, etc.).
  • the coupling element 14 (see also FIG. 6) has, in addition to the already described radial flange 17, one or more sleeve segments which define one or more cylindrical coupling sections 20 which correspond to the outer surface 12 of the running nut 4, which also serves as a mounting section.
  • the coupling element 14 is formed in a clasp-shaped, wherein the clasp opening. W is so large that it can receive the throttle linkage 22, which extends from the gas take-off 2 into the housing 3.
  • further recesses 23 are formed between the coupling sections 20, so that the individual coupling sections can be bent more or less elastically radially outwards.
  • the dimensioning of the coupling element 14 and the choice of material is made so that the coupling element 14 with a certain bias and, if necessary. a sub-tolerance can be postponed in the expanded state on the nut 4 and then spans on this elastic.
  • the friction-locking connection thus formed is so strong that all axial and circumferential loads can be transmitted from the coupling element 14 to the shell elements 7a, 7b.
  • the retaining sleeve 13 has in its upper region a recess 28 (see Fig. 3), but has a total of a closed annular shape.
