Abstract

The component has a locking arrangement, which is detachably fixed at a hinged position. The arrangement is formed in such a manner that the hinged position is engaged and/or removed under deformation of the arrangement, when a preset locking force and/or unlocking force act on the arrangement. The arrangement has a holding bolt (22) and a locking latch (26), which is engaged with the holding bolt in the hinged position, where the holding bolt and/or the locking latch are elastically deformable during locking and unlocking of the arrangement.

Description

The invention relates according to the preamble of claim 1, a hinge member for connecting a shoulder support with a handgun, so that the shoulder support is arranged between a folded and unfolded position about a pivot axis pivotally mounted on the weapon. From the US 2,405,758 A a hinge member is known in which a latching arrangement is provided which removably fixes the retracted position. In this case, the latching arrangement is formed so that the retracted position under elastic, spring-loaded adjustment of the latching arrangement with effect of a particular latching or disengaging force is ingestible or canceled.

folded is called in this context, that the buttstock rests on the weapon, and unfolded means that the shoulder rest an extension the weapon forms to the rear.

The Invention also relates to a shoulder rest with such a hinge component, a handgun, especially a grenade weapon, which with a such shoulder rest is provided (claim 15) and a weapon assembly with such Handgun (claim 19).

The hereinafter used position designations apply from the point of view of Protect for a weapon, he is in normal readiness to fire aligned. The weft direction points horizontally forward.

foldable shoulder rests are in various designs known. Such shoulder rests can be folded or folded so that they below, above or laterally rest against the weapon. The pivot axis is thereby by a hinge at which the shoulder rest or a portion of the shoulder rest adjoin can be pivoted forward, so that the weapon when folded buttstock has particularly compact dimensions. Such a folded weapon can easier to stow and reduces when carrying the Danger in the equipment or in terrain to get caught.

So that the shoulder rest remains folded, it is fixed by a locking mechanism. Such a known locking mechanism is in 11 shown. Position I shows a shoulder support part (left end) in the unfolded position and position II shows it in the folded position. The locking mechanism is formed by a locking lever (H) and a nose (N) on the hinge. In the unfolded position, the lever is located in a cavity formed between the rear end of the weapon and the front shoulder support end. Upon collapse of the shoulder support end, the locking end (E) of the locking lever (H) slides along the outer surface of the hinge eye until the end falls behind a lug (N) on the hinge eye. The rear end of the shoulder rest is locked in the folded position on the weapon (item II). Over the operating end (B), the locking end (E) can be released from the recess, and the shoulder support end can be folded out about the pivot axis (Pos. I). The unfolded position of the shoulder rest secures another locking mechanism.

So a locking mechanism has disadvantages: First, there is the lock very close to the pivot axis. That is, at the shoulder rest end attacking shear forces work with a very big one Lever and cause huge Forces between the safety lever and the hinge nose or in the hinge itself. The locking mechanism must therefore very resilient be to damage and increased Wear too avoid. On the other hand, the mechanism can pollute because he fully open when folded shoulder rest. This can cause that the Lever for unlocking the shoulder rest difficult or impossible to press is, i. the shoulder rest can no longer be unfolded. The weapon can only be used to a limited extent be and precise goals is not possible. Finally exists also the danger that one or several fingers which actuate the lever for unlocking Unfolding the shoulder rest be trapped. The leverage ratios can cause high clamping forces, which can cause serious injury to the hands.

From the US 3,369,316 A a folding shoulder rest is known in which a protruding locking head is provided on the weapon housing, which releasably engages in a corresponding receptacle with the shoulder support folded or folded. Since the locking head protrudes from the weapon housing, it represents a possible risk of injury when handling the weapon. There is also the danger that the protruding locking head is sheared when using the weapon. The shoulder rest is then no longer lockable in the folded position.

From the DE 10 2004 050 963 A1 a mechanism is known in which a magnetic element fixes the shoulder rest in the folded position. Here, additional magnetic elements or magnetizable counterparts on the shoulder support or on the weapon housing are required to fix the shoulder support in the folded position.

In the from the US 3,369,316 A and the DE 10 2004 050 963 A1 known designs are the connecting the shoulder rest with the weapon Each hinge element is provided with a locking mechanism which fixes the shoulder support in the unfolded position. For fixing in the folded position, additional retaining elements on the shoulder support shaft itself and / or the weapon housing are required.

At the time of the US 2,405,758 A known embodiment, from which the present invention proceeds, an elastic latching is realized. Here, however, a guide pin and a compression spring is additionally required to realize the necessary guidance and the input and / or Ausrastkräfte.

outgoing From this prior art, it is the object of the present Invention, a fixation of the shoulder rest or a folding stock in folded position represent the high reliability at least reduces the disadvantages presented.

These Task solves the hinge member according to the present Claim 1.

there is on the hinge component itself, which is the shoulder support with the weapon case or the weapon connects, a locking arrangement is provided. These is designed to be the folded position detachable fixed, whereby to ingest (fold in) or lift (unfold) a latching or disengaging force is required, which the latching arrangement correspondingly elastically deformed. To take or pick up the folded position is only the latching or disengaging on the shoulder rest applied. The operation a special locking lever deleted.

Thereby, that the Locking arrangement is provided on the hinge member itself, are none additional Holding or fixing elements on the shoulder support shaft or on the weapon housing or the weapon itself required. So there are no design restrictions or requirements for the weapon or the weapon housing or the shoulder rest. In order to This hinge component is universal on virtually all small arms (Rapid-fire rifles, submachine guns, grenade weapons) in conjunction with various shoulder support versions (fixed, adjustable in length, frame-like, closed) usable.

The Further developments according to claims 2 to 5 relate to embodiments of this locking arrangement. According to claim 2, while the locking assembly has a transverse to the pivot direction retaining bolts on. The arrangement of the retaining bolt allows transverse to the pivoting direction an arrangement in which the retaining bolt at its two ends in the hinge member can be fixed and a corresponding locking element transverse to longitudinal axis of the retaining bolt can attack it. This design allows especially high holding forces between the two elements. These are especially necessary when the latching arrangement are arranged near the pivot axis, and only a comparatively short lever arm for fixing the hinge component or the shoulder rest is available in folded position. The elastic Deformability of the retaining bolt and / or the locking element when Locking in and out permits simple and effective constructions. According to claim 3, the locking path in a simple manner by the thickness of the retaining bolt (Diameter) and a suitably shaped recess on the locking element be defined. This detent path determines the force curve when and disengagement. Depending on the version can so that the courses the latching or disengaging force are affected and the desired locking characteristic be set. According to claim 4, the locking element to the retaining bolt arranged elastically deformable or formed. Elastic deformable means here that the Locking element either self-deforming or elastically adjustable - for example as Sprung lever - is executed. So is over the design or arrangement of the locking element, the desired voltage or spring force adjustable, which determines the required latching or disengaging force.

According to the training according to claim 10, the operating surface can be carried out in this way, that she either by hand or with a tool is operable around the shoulder rest to fold. A pure tool operation is desirable if it should be excluded that the slide accidentally operated by hand can (for example, in a sniper rifle) and the shoulder rest unintentionally collapses.

Becomes the control surface executed according to claim 11 in alignment with the surrounding outer surface of the shoulder rest, so are on the weapon or on the shoulder rest no projecting surface elements present when accidentally operated or when striking of the locking portion of the weapon on an object from the shoulder rest solve their unfolded position could.

claim 12 relates to a shoulder rest with a hinge component indicated above, wherein the shoulder rest a has retractable or extendable shaft end. Such shoulder rests are adjustable to the anatomical conditions of each shooter and inserted Position even more compact than conventional Shoulder rest executable. Especially with such shoulder rests it is advantageous if all the folding and fixing functions in the hinge component united.

claim 13 concerns a shoulder rest, when the shoulder-side end - usually the shoulder pad - only one Frame assembly is connected to the hinge assembly and the shoulder support itself is arranged hinged on the top of the weapon. At this execution can the shoulder rest especially easy to do be, and it will ensure that everyone is on the side of the weapon arranged control or coupling devices even when folded buttstock accessible and functional cartridge cartridge, safety lever, loading lever, swing-out tube, etc.).

According to claim 14, the frame has a recess, which is one on the top can accommodate the weapon arranged sighting device. This is on the one hand the collapse of the shoulder support even with mounted visor possible, on the other hand, such a sighting device, which is usually special shock and shock-sensitive, with folded-in shoulder rest - ie during transport - additionally from protected surrounding frame.

claim 15 concerns a handgun having the above-described buttstock is provided, and in particular is designed as a grenade weapon. According to the training according to claim 16, the handgun while a Koppelein direction on, with which they are solvable can be coupled to another weapon. This allows a special flexible use of different weapons. For example such a rapid-fire rifle and a grenade weapon, depending on the mission, together or independently usable. According to claim 17, the coupling then takes place via a Picatinny rail, a bayonet mount, a gas take off or a bolt connection. It can Several coupling devices are combined to the stability of the coupling to increase. According to claim 18, the handgun is designed as a grenade weapon and claim 19 concerns an armament arrangement in which two weapons are linked together coupled, wherein a weapon is a handgun according to the above specified claims is.
