Abstract

The present invention relates to a small firearm, and in particular to a rapid-use weapon (2) comprising a shoulder support (3) that can be pivoted around a hinge (4) arranged on one side of the weapon (2). The weapon is pivoted to occupy a position which extends backwards and engages the locking elements 8, 13 mounted on the other side of the weapon 2. According to the invention, the locking elements 8, 13 are inseparable at least under normal lateral loading so that an inorganic form with a rigid rear shaft is formed. The present invention also relates to a shoulder support of the above type.

Description

Shoulder support for small firearms and small firearms {HAND FIREARM AND A RIGID SHOULDER SUPPORT THEREFOR}

The present invention relates to a small firearm, and in particular in accordance with the preamble of claim 1, which can be pivoted around a hinge mounted on one side of the weapon to occupy a position forming a rearward extension of the weapon and in the process the other side of the weapon. An automatic rifle having a shoulder support that engages a catch mounted thereon.

The invention also relates to such a shoulder support itself (claim 7).

Swivel shoulder supports are provided in DE 12 13 303 B to provide firm fixation and low wear.

In the use of the positional term in the following document, the firing point direction proceeds from a horizontally aligned weapon in the normal firing standby state with respect to the front.

Folding shoulder supports have long been known. These shoulder supports can be folded down so that they rest from below, above or side to the weapon. These weapons always have a catch and, in the case of the German MP 38/40, a hinge extending horizontally, for example. With the help of this hinge, the shoulder support can be pivoted forward and the position of the shoulder support can be detachably fixed by the catch.

In the case of the named shoulder support MP 38/40, the axis of rotation of the catch and hinge is closer. This first prior art provides a very light and compact design, but rather a rocking hold. This shoulder support is incompatible with a conventional rear butt after at least some use in its use, because the catch is easily worn. The use of plastic only as a folding butt and inorganic material inevitably leads to further distances between the hinge axis and the catch position, because the specific flexibility of this plastic requires a drastic reduction in generating force and Because of the light weight of the larger design of the swing mechanism and the greater distance from the catch and pivot, it is still acceptable.

Thus, in the case of the known German Rifle G36, it has been found that the named shoulder support is installed at least as tightly as the fixed rear butt when it is not pivoted too often.

In the case of known rifle, for example the Soviet Union AK 74, there is a design with or without a foldable shoulder support adjacent to each other. In many cases the infantry is more practically equipped with a fixed shoulder support rather than a foldable shoulder support. On the other hand, foldable shoulder supports are required for tank bottles, motorcycle messengers, etc., because these soldiers are frequently placed in a limited environment where the use of a rifle with a rigid shoulder support is impossible or at least burdensome.

However, rifle manufacture of two different designs is not only expensive, but also logistically impractical. It has also been found that a rifle with a folding butt, which is also a design with a rigid butt, is an indication that the bearer is a special case. As a result, many soldiers acquire as much rifle as possible with a folding butt, resulting in a desire to ascend from the military class, at least in speculation. However, this environment ensures that at least the rifle with a folding butt on the display sometimes goes into the misoperation area.

The known German Rifle G36, on the one hand, is equipped with a folding butt to allow only one model on the one hand and to take into account the representative needs of soldiers on the other. However, within a relatively short time, rigid butts have been found to be more appropriate in some cases.

Summary of the Invention

From the foregoing description of the prior art, it is an object of the present invention to find the most economical solution to the problem of having one and the same rifle model with optionally folding butt rear butt. In the process, when the same case design is provided for both versions, these two versions must be similar to each other so that a version with a rigid rear butt can be taken for the folding version.

This object is solved by taking a catch (claim 1) which cannot be detached in the case of at least normal lateral loads on the basis of the prior art described at the outset.

In this regard, the present invention does not proceed from a rifle with a rigid afterboard butt or rigid shoulder support attempted to make it customarily flexible, and a foldable shoulder that can be inseparably fastened in a position extending the case of the weapon. It proceeds from a rifle with a support. Thus, experience has shown that the best design for a folding butt can be selected first, and then the best fit configuration is selected. The term “in fact cannot be separated” should be understood that the separation can only be carried out by weapons mechanics and not by a soldier with a rifle.

In this way, several advantages are achieved, the biggest advantage of which is that there is no change in the rifle or weapon (for example, an automatic rifle) and the rifle and shoulder support are used as they are used in the case of a weapon with a folding shoulder support. Is that. It is true that this design is more expensive than a simple rigid support, but this cost is more than offset by the savings of a separate model. Only the catch is changed, so that the movable catch portion is mounted to the shoulder support. However, if this catch portion is made of plastic, it can be made into a mold of the catch portion by an adapter, so that the catch portion does not require, for example, an operating handle.

A further advantage is that the rifle can be designed to open in case of catch overload, for example when tilted off. Thus in many accidents the shoulder support can be folded before it is destroyed.

In this connection, for example in the case of a fold version, the helical pin used on the hinge side can be replaced by a rigid shoulder support by means of removable retaining bolts. This is appropriate in the case of certain weapons to remove the rigid shoulder support when cleaning the weapon.

The design according to the invention preferably comprises a selected folding mechanism, which is formed of elements which are removed far from each other, which thus holds the shoulder support in spite of the tolerances and the choice of plastic for these elements. Is particularly preferred.

The catch can be made in a number of different ways, and in addition to presenting a foldable shoulder support provided in the presence of a finished weapon, it must present a rigid shoulder support in accordance with the present invention, and compromises must be made. However, according to one particularly simple design of the catch, the catch is formed by a rear facing bracket mounted on the other side of the weapon, which presents a recess to which the spring-acting slide bar installed on the shoulder support engages, the slide bar being It does not have a force absorbing element that projects outwardly (claim 2). This slide bar can be the only element between the rigid shoulder support and the foldable shoulder support, presenting a handle that the slide bar of the foldable shoulder support can easily obtain and can be pushed against the force of the spring by the handle. The resulting shoulder support is released for folding, while the slide bar according to the present invention protrudes backwards and presents no elements that can be used for the operation of the slide bar.

To block the slide bar against the outside, the recess can be designed as a blind hole. This prevents the possibility of contamination since the catch does not open. However, it is preferable that the recess is a through hole (claim 3). Here, in the case of a foldable shoulder retard, the shoulder support is fully fixed or not, contamination is limited and inspection by eye contact is possible, as well as the tool (in the case of a rigid shoulder support according to the invention) Can be inserted into the recess, the tool being formed on the front side complementary to the slide bar, so that the slide bar can be moved by the tool without any difficulty and in particular without causing damage.

It is, of course, forbidden for soldiers to use weapon pokes around the holes or to carry screwdrivers or the like near the brackets. However, in an emergency, for example, before a soldier rides on a limited lander, the tool may leak out, so that the fixed shoulder support can also be folded without special expertise. Once the soldier has enough space again, the shoulder support is simply unfolded, the catch bar's slide bar engages with the associated hole, and the rifle is again provided with a rigid shoulder support.

There are various possibilities for folding the shoulder support up and down, for example in the case of the initially named MP 38/40 there is a shotgun in which the shoulder support is folded down, which is folded up.

However, according to the invention it is particularly preferred when the pivot axis of the hinge extends parallel to the relevant side of the weapon (claim 4), so that the shoulder support lies laterally with respect to the weapon when it is folded forward. A particular advantage of this design is that neither the aimer nor the magazine and the handle are surrounded by the shoulder support and are unlikely to be damaged in the process. In other respects the hinges or catch brackets are externally located prior to gripping or aiming, so they can be made relatively large and robust and do not compromise the usefulness of the weapon. Therefore, the rigid shoulder support can be mounted, like the conventional rear butt is firmly installed on the weapon without rocking.

In this case the hinge can be installed on the left or right side of the weapon. However, the hinge is preferably installed on the right side of the weapon (claim 5). If the catch collapses, for example due to the destruction of the slide bar, the joint (if it is a right-handed sniper) is folded inward, and further folding is prevented by the body of the sniper. This makes the operation safer even in extremely rare cases where catches fail.

The foregoing is directed to the fact that the specific and limited elastic flexibility of the parts of the joint contributes to allow the shoulder support to be fully rigidly mounted to the rifle, as with conventional rigid rear butts. For this reason, it is preferred according to the invention that all or most of the catch and hinge are made of plastic (claim 6). Although the case of the weapon must be fairly rigid, it can be made to exhibit the required flexibility in the case of the shoulder support and / or in the case of parts of the catch and as a result is better protected from breakage in other respects.

In other respects the invention relates not only to a small firearm with a folding butt, but also to the shoulder support (claim 7) itself, which can be produced simultaneously or separately for an already existing weapon. In the process, parts of the shoulder support according to the invention can be made redundant to replace existing worn weapons with this, since again a completely strong sheet of shoulder support is produced (due to spare). In addition, since the shoulder support according to the invention cannot be folded in daily use, further wear and cracking of parts such as brackets and hinge parts on the case of the weapon is eliminated. Thus the weapon can be used continuously without loss of its usefulness.

A particular and non-limiting embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a horizontal cross sectional view of a joint for strong mounting of a shoulder support.

A part of the case 2 is shown in FIG. 1, in which two eyes 6 of the rear left bracket 7 and the right hinge 4 are molded in a single piece. The bracket 7 has a continuous recess 13. On the back of the case 2 (right side of the drawing), a shoulder support 4 is disposed on the same plane as the case, and on the right side, an eye 6 assembled with the other eye 6 is provided, and a hinge ( The removable retaining bolt 9 perpendicular to 4) cannot be removed without the tool.

The shoulder support has a transverse hole 10 which opens to the left side (lower side of the drawing), in which the spring 5 is first inserted in sequence and then the slide bar 1 is inserted. The slide bar 1 has a stop 11 in the process, which is compressed during its installation and then bounced back to engage the recess 12 of the bore 10, which limits the stroke of the slide bar. To ensure that the slide bar cannot be disassembled without difficulty.

The slide bar 1 has a nose 8 which is coupled to the recess 13 of the bracket 7, which nose cannot be detached again after being locked in position because the slide bar 1 This is because) does not have protrusions that can be accessed from the outside.

The engagement of the slide bar 1 into the recess 13 of the bracket 7 is excessively lateral to the right (upper side of the figure) through the bending of the parts, all of which are made of plastic, except for the retaining bolts 9. In this case, the slide bar 1 is freed, whereby the shoulder support 3 is not broken and in particular the bracket 7 is not pulled out.

When a tool complementary to the projection 8 of the slide bar 1 is inserted into the recess 13 of the bracket 7 from the left side, the slide bar 1 can be pushed back with it and the shoulder support 3 Can be turned as an exception.

Rifles with pivoting butts are provided with a slide bar, in which case the left rear (lower right side in the drawing) is molded with a trigger extending to the left (lower side in the drawing), followed by the bracket standing outwards and the sniper with the slide bar The trigger must be depressed in order to be able to move to the right and tilt the shoulder support 3 forward.

Due to the particularly good and strong retention the invention is particularly suitable for rifle, in particular for sniper rifle or automatic rifle. However, the shoulder support shown may also be mounted on a machine gun or automatic rifle or a small automatic rifle.
