Abstract

A housing for a rifle, comprising a first anchoring for a barrel, a second anchoring for a butt, a guide for a breech that can be locked with the barrel, and a seat for a trigger that interacts with the breech. The housing is subdivided into a lower part and a separate upper part which can be firmly connected thereto. The lower part forms the anchorings for the barrel and the butt and the seat for the trigger and the upper part forms the guide for the breech.

Description

The present invention relates to a housing for a rifle, with
a first anchorage for a run,
a second anchorage for a shaft,
a guide for a lockable with the barrel closure and
a receptacle for a cooperating with the closure trigger. Such a housing is in WO 03/076863 shown.

Such housing provide the central element of a rifle there, which supports the individual components such as barrel, shaft, closure, trigger and magazine and ensures the power transmission between these assemblies.

For static and dynamic reasons, the known housing of this type are currently made of one piece. For the construction of different types of rifles with different application requirements, which are reflected in different assemblies and materials, a separate housing must currently be developed, manufactured and officially approved for each type of rifle, which is a high design, manufacturing, testing and logistics.

The invention has for its object to overcome the disadvantages of the known constructions and to provide a rifle housing, which allows the construction of rifles in a high type and quality variety in a simple and cost-effective manner.

This object is achieved with a housing of the aforementioned type, which is characterized according to the invention in that the housing is divided into a lower part and a separate, but firmly connectable upper part, wherein the lower part of the anchorages for the barrel and the shaft and the receptacle for the trigger and the upper part forms the guide for the closure.

In this way, a housing is created for the first time, which allows the modularization of a rifle to the greatest extent possible. The invention is based on the finding that the closure guide of a directly lockable with the barrel closure, such as a rotary piston closure, not subject to the same high mechanical stresses as that housing part, which produces the power transmission from the barrel to the shaft. Based on this knowledge, a modularization is created in a closure-carrying upper part and a system-supporting lower part. This makes it possible for the first time to realize a variety of different weapon types with a single base as a system carrier and changing tops for the closure.

For example, military designs require particularly robust surfaces that can be provided by a corresponding top - in conjunction with correspondingly designed other assemblies such as shanks, etc. - hunting weapons are intended to provide the opportunity for finishings and ornaments, e.g. can be met by a plastic top, army weapons should be particularly lightweight, which can be achieved for example by aluminum production, etc .; All this can be achieved with one and the same lower part as a system carrier in conjunction with varying tops for the closure guide.

Due to the modularity of the upper housing part and the lower housing part and their arbitrary combinability, the number of different housings to be manufactured can be reduced to a few basic types of upper parts and lower parts. This simplifies not only the warehousing and distribution logistics, but also the production itself: The division of the housing simplifies the shaping and milling, since the two parts can be manufactured separately, and the easier milling results in less waste.

In addition, there is the advantage that for the official bombardment of a new weapon, which all at the firing must be subjected to power-conducting parts, only the run and the closure must be checked, since the upper part plays no force-bearing role in the firing. This greatly simplifies the bombardment and type testing of new types of rifles.

A particularly advantageous embodiment of the invention is characterized in that the upper part is modular exchangeable connected to the lower part. This allows the user himself and even in the field use his rifle system modular from different top and bottom parts and run, shaft, trigger, closure and magazine assemblies assemble. The modular interchangeability has the additional advantage that in the case of a housing defect only the affected housing part must be replaced.

The modularization of the housing according to the invention opens up the possibility, according to a preferred embodiment, of manufacturing the upper part and the lower part from different materials. As a result, it is possible, for example, to use particularly stable materials for the force-conducting lower part and less expensive materials for the non-force-conducting upper part. Or it is alternatively - because of the largely concealed installation of the base - just used particularly inexpensive materials for the lower part and particularly high-quality materials for the outer visible upper part. Both possible combinations are within the scope of the present invention.

A particularly preferred choice of material is to manufacture the upper part of plastic and the lower part of metal. This combines high strength with the greatest possible cost savings.

In this sense, it is particularly advantageous if the upper part machined at least on its outer surface, painted, coated and / or finished. As a result, special requirements can be met with the help of the upper part based on one and the same lower part.

The top may be connected to the base in any manner known in the art. According to a preferred embodiment of the invention, the upper part is anchored by means of a dovetail joint on the lower part. As a result, the upper part can be pushed onto the lower part during assembly of the weapon. The fixation of the dovetail connection can be achieved for example by securing screws or by a positive fixing of the upper part between barrel and shaft.

According to a preferred feature of the invention, the guide is a per se known axial guide for a rotary piston closure. Rotary piston closures are self-sufficient, compact units, which can thus be easily guided in the upper part.

According to further preferred features it is provided that the lower part has a receptacle for a magazine, a third anchoring for a forearm and / or a fourth anchoring for lateral Schaftwangen or accessories. In this way, can be built with the housing according to the invention a large number of different types of weapons.

The invention will be explained in more detail with reference to an embodiment shown in the accompanying drawings. In the drawings shows

• Fig. 1 a fragmentary illustrated rifle with a housing according to the invention in a exploded perspective view;
• Fig. 2 the housing of the invention in an exploded perspective view in detail; and
• Fig. 3 the housing of the invention with attached side sheep cheeks in cross section.

Fig. 1 shows a rifle 1 of modular assemblies, which are mounted on or in a central housing 2. The assemblies are in detail a barrel 3, a forearm 4, a (rear) shaft 5, a rotary piston closure 6, a magazine 7 and a modular trigger 8, as known in the art.

According to Fig. 2 is the housing 2 in a lower part 9 and one separate, but firmly connected to the lower part 9 upper part 10 divided. In the upper part 10, a guide 11 is formed for the closure 6, in the example shown in the form of a longitudinal, downwardly open guide trough known type.

The lower part 9 is equipped with a first anchorage 12 for the barrel 3, more precisely for running lugs 13 formed at the root of the barrel 3, which engage between latching bars 14 of the lower part 9 ( Fig. 1 ). At its opposite end, the lower part 9 has a second anchoring 15 for the shank 5, for example in the form of a shoulder for engagement in a complementary recess 16 of the shank 5.

In the region of the first anchoring 12 for the barrel 3, optionally a third anchoring 16 for - if available - the forearm 4 or a bipod, etc., can be provided. On both sides of the lower part 9 can also have a fourth anchor 17 for - if present - lateral Schaftwangen 18 ( Fig. 3 ) or accessories such as cartridge holder, rangefinder, camouflage means, etc. may be provided, for example in the form of corresponding recesses or recesses.

The lower part 9 is finally equipped in a conventional manner with a receptacle 19 for the magazine 7 and a receptacle 20 for the trigger 8. In the assembled state, the magazine 7 opens through the lower part 9 into the interior of the upper part 10, which presents itself with the closure 6 open.

When closing the shutter 6 this is locked in a bayonet-like manner with its front closure head 21 in the root of the barrel 3 and forms with this in the firing task a rigid unit.

It has been recognized that in the locked state, the upper part 10 need not exert a holding function for the closure 6, whereby for the upper part 10, another, for example, less stress-resistant material can be selected as for the Lower part 9, which produces the power transmission from the barrel 3 to the shaft 5. As a result, depending on the requirement and intended use of the lower part 9 and the upper part 10 of different materials and with different finishes, finishes, finishes, etc. are made.

For example, the upper part 10 of inexpensive plastic, lightweight aluminum, etc. are made. The lower part 9, however, is preferably always made in one and the same embodiment, for example made of aluminum or steel. By combining corresponding upper parts 10 with corresponding lower parts 9 can be realized with a few basic components numerous different types of weapons.

Fig. 3 shows the anchoring of the upper part 10 on the lower part 9 via a detachable dovetail connection. The dovetail connection comprises corresponding projections 22 on the upper part 10 and complementary projections 23 on the lower part 9.

The lugs 22, 23 of the dovetail connection extend only over a part of the length of the upper part 10 or lower part 9, so that the upper part 10 can be placed offset on the lower part 9 and then displaced in the axial direction to the lugs 22, 23 into engagement bring to. In the engaged position, the dovetail joint may e.g. be fixed by means of locking screws 24, or the upper part 10 is simply set during assembly between 3 barrel and lower part 9.

The invention is not limited to the illustrated embodiments, but includes all variants of modifications that fall within the scope of the appended claims.
