The invention relates to an automatic weapon composed of several assemblies, the barrel with a locking piece, the actual weapon housing, the buttstock and the fume cupboard with the handle form the individual assemblies. Weapons of this type are known.

The invention is based on the object of creating a weapon of this type which is used to achieve a weight reduction allows, e.g. to use materials for the weapon housing that are due to the forces to be transmitted were not previously suitable as load-bearing components.

According to the invention, this object is achieved in that the assemblies run with the non-running Locking piece, weapon housing and shoulder rest connected to the locking piece Tie rods are held, with the trigger box as additional stiffening with at least two of the is connected to the assembly groups lined up on the tie rods. As a result, the shot in the ao Weapon occurring longitudinal forces absorbed in a particularly advantageous manner by the tie rods, so that the hitherto these forces absorbing weapon housing, which for this purpose so far has always been made from a comparison strong sheet metal was made, now from comparatively thin and possibly Can be made of light metal sheets or plastic.

In order to reduce the structural effort and to save weight, the aforementioned tie rods can be used advantageous at the same time as guide elements, ζ. B. for the weapon lock, use. Here you can In an advantageous embodiment of the invention, the tie rods consist of tubes, the free ends of which Have annular grooves that after the weapon housing has been pushed onto the tie rods for inclusion a retaining latch are used, and which are screwed into the locking piece.

Considerable weight savings result in the context of the invention when the weapon housing from a shell part in lightweight construction, in particular using specifically lighter Materials such as B. light metal, fiberglass-reinforced plastics or the like. Is, in which the actually load-bearing or stressed components, such as guides for locking links, spacer rings for the tie rods, used, for. B. are poured or injected in a known manner.

In order to use several coupled assemblies: barrel with locking piece, Weapon housing, shoulder rest, to achieve a backlash-free connection is according to one From assemblies

compound automatic weapon

further features of the invention between the shoulder rest or its retaining latch and the Weapon housing has a spring element acting in the axial direction, for example a curved or corrugated one Leaf spring, arranged, this leaf spring expediently with its outer contours the connection cross-section the weapon housing and / or the shoulder rest is adapted. To simplify the Overall assembly, this suspension element can also be designed in a ring shape and in the area of the tie rods be provided with guides open on one side. The mentioned suspension element is also used for the rest in addition to the shrinkage that occurs during injection molding or pulling of the plastic jacket for the housing compensate.

Further details of the invention will be described using an exemplary embodiment that is shown in FIG Drawing is illustrated.

F i g. 1 shows a schematic representation of a weapon consisting of four assemblies before connecting the assemblies;

Fig.2 shows a further detail, namely on Hand ernes schematic cross-section of the weapon housing one way of fixing the Tie rods in a weapon housing in lightweight construction, z. B. made of plastic.

In Fig. 1, 1 is the barrel with the cartridge chamber !. With 3 the locking piece for the lock is designated, while at 4 the hand guard is indicated. Positions 5, 6 are two tie rods screwed to the locking piece, tubular tie rods for reasons of lightweight construction, which are provided with annular grooves 7 and 8 at their ends. The actual weapon housing is denoted by 9, and 10 is the shoulder rest.

The connection of the aforementioned parts takes place in such a way that the weapon housing 9 is expedient via corresponding guide, recognizable at 5 '

grooves in the housing along the tie rods 5, 6 in the direction of the parts 1 to 4, d. H. on the group »locking piece« is postponed, at the end of the fixed Verklammerang these two assemblies is effected by means of a retaining bolt 11, which with its locking openings 12,13 in the Ring grooves 8 and 7 of the tie rod is inserted. Before this insertion, the corrugated or curved leaf spring 14, which at 15 'is provided with guides that are open on one side along the tie rods 5, 6 is postponed. Then the shoulder rest 10, which is in the area of the weapon housing facing Front end has a groove or detent (not shown), with this groove on the hook-shaped Extension 15 of the retaining bar 11 is placed. Then the fourth assembly, consisting from the trigger box 16 with handle piece 17, which is a structural unit with the magazine well indicated at 18 forms, can be used as an additional link for the three remaining assemblies. To this Purpose it is only necessary to attach the named parts via socket pins, which are in the bores 19 to 22 ' be introduced to connect with each other. The curved or corrugated leaf spring ensures this 14, which can be tensioned effortlessly under the leverage of the shoulder rest, a backlash-free connection of the individual assemblies with each other. Likewise, differences in the longitudinal direction compensated.

Instead of the in FIG. 1 drawn two tie rods can for example - as FIG. 2 illustrates - also several, e.g. B. four tie rods can be used. To ensure an exact fixation of the To ensure tie rods in the housing, spacer rings 23 can be provided that are firmly attached to the housing connected, e.g. B. are cast or injected into the housing shell. One can, however, also specialize Provide guides for the breech or other parts in the weapon housing 9, as in the middle part of Fig. 1 at 24, 25 is indicated.

The handle 17 is intended in the lower part of Fig. 1 as a stamped sheet metal part, but could also be Be executed light metal casting. A production of the handle piece from plastic would certainly also be possible possible. As is known, the trigger system is combined in a special trigger box and inserted as a whole in the handle, or the trigger parts are directly in the handle ~ piece built in.
