Description

adapter component

The invention relates to an adapter component for receiving attachments for a weapon. Such an adapter component serves as an intermediate carrier for attaching ancillary equipment such as (night) aiming devices, illumination devices, bipods, grenade launchers, sighting devices or the like to firearms, and particularly to semi-automatic or automatic firearms.

Direction details such as front, back, top, bottom, right and left are indicated from the point of view of a shooter who holds the weapon properly in the stop. In the following, also such elements which connect other weapon components (for example a barrel) to the actual weapon housing are considered as a weapon housing component. Thus, for example, a running nut also applies as Waffengehäusebauteil.

From EP 0 082 257 a slotted ring is known to which can be attached via a carrier optical accessories. The ring surrounds the gun barrel and is clamped for attachment directly to the barrel. WO 2004/085950 discloses an adapter which surrounds a sleeve surrounding the barrel in a sleeve-like manner; the adapter is thereby fixed in a form-fitting manner via a locking element which engages in a ring formation on the sleeve and via a design which is in a complementary manner Counter-training on the weapon intervenes, secured against twisting.

The attachment directly to the barrel carries the risk that all deformations and thermal stresses of the barrel are transmitted directly to the adapter element. As a result, the shot accuracy, especially if the adapter element sighting devices are mounted, are adversely affected.

Although the positive coupling to a sleeve surrounding the barrel creates a decoupling of barrel and adapter and thus of the attachments, but it makes high demands to the manufacturing accuracy, since the adapter element in all possible operating states of the weapon and also to different weapons in a well-defined position should be set or attachable.

The object of the present invention is therefore to provide an adapter whose attachment to the weapon is improved.

This object is achieved by the adapter component according to claim 1. The adapter component surrounds a barrel-fixed weapon housing component in the manner of a sleeve. It can be frictionally coupled with an inner surface region to an outer surface region of the weapon housing component. The surface pressure required for the frictional engagement between the inner surface region of the adapter component and the outer surface region of the weapon housing component is effected by means of a tensioning element, which elastically deforms the adapter component at least in regions during adjustment. That is, the adapter element may have areas that deform more when adjusting the clamping element than other areas that deform only slightly elastic. By appropriate design of the adapter component, it is possible to realize a relatively large game between the sleeve and the adapter component with dissolved clamping element. As a result, the manufacturing tolerances for sleeve and adapter component can be increased and thus the manufacturing cost can be reduced. The adapter component is in a defined position on a weapon, especially on a rapid-fire weapon to install, in such a way that it can also accommodate sighting and influences are kept away from the adapter component on the barrel and vice versa. In addition, the corresponding interfaces to the weapon itself and the adapter component with comparatively low demands on the manufacturing accuracy can be produced. Thus, the processing cost can be limited. Claim 2 relates to an embodiment in which the

Weapon housing component is designed as a barrel in the weapon housing fixing sleeve. Such a sleeve or nut provides a particularly good basis for fixing the adapter element with respect to the barrel.

In the development according to claim 3, the adapter component is equipped with a plurality of coupling jaw segments, on each of which an inner surface region is formed which in each case at least partially touches the outer surface region of the weapon housing component. In this embodiment it is e.g. possible to provide the weapon housing member with a cylindrical outer surface, while the inner surface portions of the coupling jaw segments are made more or less flat. In this case, there is line contact between the inner surface areas and the outer surface area.

In the embodiment according to claim 4, the adapter component is formed prismatic along the axis of the soul. Thereby, the adapter component can be made so long that it can also accommodate attachments that require a correspondingly long guide parallel to the axis, e.g. Visor devices, or it is possible to form the adapter component as a hand guard, which largely surrounds the barrel in the front region of the weapon. According to claim 5, a special intimate coupling between the adapter component and weapon housing component is possible if the outer surface and the inner surface of the coupling jaw segments are each made correspondingly cylindrical. Cylindrical surfaces are easy to manufacture and ensure large-area coupling of the elements.

The claims 6-10 relate to the design of the adapter component, the clamping element and their interaction. According to claim 6 in each case elastic or articulated connection structures are provided between adjacent Koppelbackensegmen-, which allow the elastic deformation of the adapter component for coupling. Thus, the coupling jaw segments can be made relatively stable, so that high area Pressings between inner surfaces of the coupling jaw segments and the outer surface of the sleeve can be constructed. At the same time, they are so movable relative to one another by the connection structure that the adapter component can adapt to the circumference of the sleeve with the desired tolerances. The design of the connecting structure according to claim 7 has the advantage that the channels open towards the core axis can be formed so that they can accommodate other weapons elements associated with the barrel, for example a gas pressure loading mechanism extending between the outlet side gas removal and the closure mechanism. Thus, the adapter component can be pushed from the front, without the dismantling of elements in the mouth area on the barrel or the weapon housing component. According to claim 8, the clamping element acts on the connection structure. This reduces local loads on the coupling - jaw segments. Particularly simple, the clamping element according to claim 9 and 10 can be designed, the design according to claim 10 as a clamping screw, which engages directly into a threaded bore on the adapter component, is particularly easy to use.

To secure the clamping screw against loosening and removal the designs according to claim 11-14 are provided. The embodiment according to claim 12 allows the withdrawal or unscrewing the clamping screw by the resistance of a spring element is overcome, which prevents accidental or unwanted loosening, while the developments of claim 13 and 14 prevent the unwanted removal (claim 13), so that also In use, a loss of the important clamping screw can be excluded, but according to claim 14 still a removal or disassembly, for example, for maintenance, with tools is possible.

For additional securing of the adapter component in the axial direction, the clamping element can engage positively in a ring groove formed on the weapon housing component (claim 15). This additional positive locking allows a precise axial Arrangement of the adapter element on the weapon and prevents axial slippage even at high axial loads. In accordance with claim 16, the adapter component with respect. set the weapon in a defined angular position. In combination with the frictional engagement, these structures can be formed on the adapter component or on a weapon component such that a defined angular position is defined during assembly, but the torsional forces themselves are transmitted via the frictional engagement. However, the structures mentioned can also be formed so strongly that they absorb torsional forces. Thus, in connection with the embodiment according to claim 15, the adapter component respect. the weapon axially and positively fixed in the circumferential direction.

Claim 17 relates to a design of the clamping element, so that it can be operated without an additional required tool. According to claim 18 carries the adapter component on its outer side mounting structures for attachment of accessories. This allows the adapter component to be adapted to standardized fastening systems (Picatinny rails, etc.).

The one-piece, in particular closed version of the adapter component according to claim 19 has manufacturing and application advantages. The adapter component can be made, for example, from almost any configurable extrusion and the design with a closed cross-section makes it largely insensitive to damage. The embodiment according to claim 20 ensures accurate positioning of the adapter component with respect to the weapon in the axial direction and allows high axial loads without the adapter component shifts to the weapon. Claim 21 relates to a weapon or a weapon assembly comprising an inventive adapter component.

An embodiment of the present invention will now be described with reference to the figures. Showing: 1 shows a perspective view of a weapon with an adapter component according to the invention;

Fig. 5 is a perspective view of a clamping screw for a clamping element according to the invention.

1 shows an adapter component 1, which is arranged in the running region of the weapon 2. FIG. 2 shows the adapter component 1 with a part of the weapon 2 from FIG. 1, in which the barrel 4 and a housing component 6, on which the adapter component 1 adjoins in the assembled state (see FIG. 1), are shown. The barrel 4 is connected via the sleeve 7 with the housing member 6. Parallel to the barrel runs a gas pressure loading mechanism 27.

The illustrated in Fig. 3 partial longitudinal section through the connection area of the adapter element 1 shows the exact structure: In the closure area of the weapon 2, a locking piece 3 is arranged, in which a barrel 4 is inserted with its cartridge end 5. Run 4 and locking piece 3 are secured in a housing member 6 by the sleeve 7 is screwed via a threaded portion 8 with the housing member 6. The sleeve 7 has in the interior a paragraph 9, the attacking on an end face of the locking piece 3 arranged in the locking piece 3 run 4 in the housing component 6 fi- xed. For screwing the sleeve 7, this has radial openings 10 into which, for example, a suitable hook wrench can engage. The outside of the sleeve 7 has a substantially cylindrical outer surface 11 into which a semi-circular annular groove 12 is inserted.

4 shows the cross section A-A in FIG. 3 and makes the structure of the adapter component 1 clear. The adapter component 1 comprises four coupling jaw segments 13, which are connected to each other via radially outwardly facing connecting structures 14 in the illustrated embodiment elastic-articulated. The connecting structures are each formed by two side walls 15 and an end wall 16, each defining an approximately U-shaped channel 17.

In other embodiments, the end wall 16 can also be provided with a hinge or replaced by such a hinge (not shown). It is also possible that an end wall 16 is designed slotted, so that the entire Adapterbau- part 1 can be folded around the run 4 and the sleeve 7 around at a arranged opposite the slotted front wall hinge (not shown).

The lower connecting structure 14 is penetrated by a clamping screw 18 which attaches on one side with its head 19 at the edge 20 of a side wall 15 passing through hole and at its end a threaded portion 21 which in a corresponding threaded hole in the opposite Side wall 15 engages. In the illustrated embodiment engages the shaft 19 connecting the head 19 and the threaded portion 21 in the annular groove 12 on the sleeve 7 a. The axis 23 of the clamping screw 18 extends transversely to the running or soul axis 24 of the weapon. Thus, the adapter member 1 is positively fixed axially in the direction of barrel or bore axis 24 of the weapon. When tightening the clamping screw 18, the two side walls 15 are contracted to the lower Verbindungsstrukur 14 and thereby press each formed on the coupling jaw segments 13th Inner surface regions 25 on the outer surface region 11 of

Sleeve 7. The connecting structures 14 and to a lesser extent also the coupling jaw segments 13 can deform elastically and ensure that the inner surface regions 25 conform to the outer surface region 11.

In the illustrated embodiment, the outer surface portions 11 of the sleeve 7 and the inner surface portions 25 of the adapter member 1 are each formed correspondingly cylindrical. In another embodiment (not shown), these surface areas 11, 25 can also be designed to be flat according to each other. The sleeve 7 may for example have an octagonal outer cross-section. The inner surface regions 25 are then configured in a correspondingly complementary manner. Such an embodiment provides a rotational fixation of the adapter component 1 respect. the soul axis 24 sure. In a further embodiment, e.g. the inner surface portions 25 are made flat, while the outer surface 11 of the sleeve 7 is made cylindrical or curved. In such an embodiment, the coupling takes place via a line contact. The lines of contact run in the direction of the axis of the soul 24th

There are also embodiments (not shown) in which the outer surface regions 11 are not arranged on the sleeve 7, but on a correspondingly formed portion of the housing member 6.

In addition to the elastic-hinged coupling of the coupling jaw segments 13, the connecting structures 14 fulfill two further functions. First, they carry on their outside adapter rails 26, which are designed here as so-called. Picatinny rails. However, other suitable adapter structures can also be arranged or formed thereon. Secondly, the U-channels 17 defined by the side walls 15 and an end wall 16 form space for further weapon components. In the upper connecting structure 14, the gas pressure loading mechanism 27 extends here in this channel. The lateral U-channels 17 are here designed so that they fit here via eyelets 28, which are arranged for example on a gas take-off component 29 in the mouth region of the barrel. That is, the adapter component 1 can be pushed with disassembled or collapsed grain 29 '(see Fig. 2) from the front over the muzzle on the weapon 2 or vice versa removed to the front. For this purpose, the clamping screw 18 is pulled out of the lower connecting structure 14 so far that it is no longer in engagement with the annular groove 12 and the lower U-channel 17 releases.

To secure the clamping screw 18, a spring element 30 is provided in the edge region 20 of the adapter component 1 on the lower connecting structure 14. When the clamping screw 18 is fully inserted, this spring element 30 engages in a latching groove 31, which is formed between the head 19 and the shaft 22. The transition of the locking groove 31 to the shaft 22 is formed here obliquely, so that when unscrewing the clamping screw 18, this bevel, the spring element 30 so deformed that it can slide on the shaft 22 and thereby deformed correspondingly elastic. Once the threaded portion 21 is disengaged from the threaded hole, then the clamping screw 18 can be further pulled out of the adapter member 1. In order to prevent complete removal of the clamping screw, a further locking groove 32 is formed between the threaded portion 21 and the shaft 22, in which the spring element 30 is incident during withdrawal. The transition of this locking groove 32 to the threaded portion 21 is designed so that the spring element 30 abuts against a shoulder, which prevents further withdrawal of the clamping screw 18. The clamping screw 18 is thus captive, but releasably secured in the adapter component 1. That is, the clamping screw 18 can be pulled out so far that the lower U-channel 17 is released and also arranged outside the running contour components (such as a bayonet connection) can be passed through.

The tensioning screw shown in Fig. 5 has at its head 19 a knurling or toothing 33, the unscrewing the screw with the hand relieved. In addition, it has an inserted into the end face of the head 19 actuating profile 34, which coincides with a corresponding profile on a detachable weapon component, so that for lo sen or fixing the clamping screw 18 no special tools must be carried, but an existing anyway weapon component , For example, a closure piece or a belt holder (not shown) can be used. The actuation profile 34 corresponds in other embodiments a conventional tool profile (hexagon socket, Torx or the like).

FIGS. 1, 2 and 3 show on the adapter component 1 a securing lug 35, which is formed in a complementary recess 36 on the upper side of the housing component 6 of the weapon 2. Securing nose 35 and recess 36 define the adapter member 1 in the circumferential direction and secure this possibly additionally against rotation. The illustrated adapter component 1 has recesses 37 in the regions of the coupling jaw segments 13 lying outside the sleeve 7, which improve the cooling of the barrel 4.

In the illustrated embodiment, the adapter component 1 is fixed only at its weapon-side end and otherwise surrounds the barrel without contact. That is, the adapter component 1 does not affect the weft properties of the weapon 2 in any way. The axial alignment of the adapter component 1 to the core axis 24 is ensured by the frictional connection in the region of the sleeve 7 between its outer surface region 11 and the clamped inner surface regions 25. In the illustrated embodiment, the adapter component 1 is made of one piece. Starting material may be, for example, a suitable extruded profile. However, there are also embodiments in which the adapter component 1 is designed to be multi-piece, eg when two halves are connected to one another via a hinge running in the axial direction and a parting line exists at the opposite end. However, the illustrated closed cross-section has the Part that the adapter component 1 is so particularly insensitive to damage and thus very robust executable.

The adapter component can also be produced as a cast or forged part or as a plastic injection-molded part or also from a composite material.

Other variants and alternative embodiments will become apparent to those skilled in the scope of the appended claims.
