Description
Anchoring element for a firearm system, as well as a firearm system with such an anchoring element.
The invention relates to an anchoring element for a firearm system, as well as to a firearm system with such an anchoring element.
The term "firearm system" inGudes firearms that have at least one first barrel and at least two modules, that is to say, structural- and/or add-on elements. The firearm system can optionally additionally have a weapon casing, but this does not absolutely have to be present, however.
The positional terms that are used in the following, such as "forward", "top", "left", etc, relate to a weapon that is positioned in an orderly manner upon the firing of a horizontal shot, whereby the direction of shooting proceeds forward. The same is applicable to statements about direction ("to the front", "upwardly", "to the left", etc.).
The article "Futuristic vision achieved" [/in GermaN] by R. Withelm, in: "DE-2: Deutsches Waffenjoumal" [I= German Weapons Journallj, 5/99, pages 672-679, as well as DE
15 261 C1, are noted as state of the' art. In this, the publication "Deutsches Waffenjoumal"
does not show the technician anything more than a ring which sits on the barrel and supports the necessary sight.
The patent documents DE 25 31 620 A, US 3 325 967 A, and FR 555 668 A depict a connecting part connectable with the barrel which has a mount for one single module which can, if necessary, be exchanged for another one. The module can, for example, be a second barrel, a telescopic sight, or a gradated sight.
In modem military hand-held firearms, it is common for optical aiming devices or other add-on elements to be attached to the weapon casing. As a general rule, supplemental parts, such as mounts or other connecting elements, which are attached to the weapon casing -2_ and which make the attachment of the add-on elements possible, are used for that purpose. The barrel of the firearm is, in most cases, thereby supported within the interior of the weapon casing, along with the breech. This construction has proven its value in many ways, since the barrel and breech are thus protected against damages from impacts or contamination. In any event, such a construction also has the disadvantage that parts of the weapon casing are also positioned between the barrel and the add-on element, such as a telescopic sight next to the connecting elements, for example. The barrel and telescopic sight are then connected with one another by means of a chain of individual parts, the manufacturing tolerances of which can be added to one another.
These "chains of tolerance" can make expensive subsequent adjustments necessary and can, in the extreme case, lead to clearance and thereby to imprecisions in the shooting pattern. Upon attaching an additional add-on element to the weapon casing, such as to an add-on firearm, for example, the chain between the telescopic sight and the longitudinal direction then becomes still longer, and the possibilities of imprecisions still greater.
The problems represented are additionally reinforced if the individual parts of the said chain consist of different materials. Because of the different thermal expansions of the individual parts upon temperature oscillations, additional problems of precision can then appear.
Now, it does lie essentially within the skill of the technician to counteract the problems represented by means of a more precise manufacturing or a suitable selection of materials.
Such measures, however, necessarily increase the manufacturing costs of the ~reann.
In addition, weapons in which the mount of the telescopic sight is attached directly to the barrel are already known from the areas of hunting and sports weapons. The chain of tolerance between the barrel and the sight is thereby shorter, which has a positive effect on the precision of the shooting pattern. Such solutions are not known from other.areas of weapons, however, particularly from the area of semi- and fully-automatic military _3_ weapons, which is presumably to be attributed to the covering of the barrel by the weapon casing that is present in these weapons.
The task that forms the basis of the present invention is that of describing an additional possibility, in a firearm system, of attaching several modules and, at the same time, of avoiding the problems of precision described.
The present invention proceeds from the knowledge that this task can be solved by means of a separate component, such as the said anchoring element. This is attached to the first barrel of the firearm system and can be connected with several of the modules (structural-and/or add-on elements) by way of corresponding mounting guides. The anchoring element thus represents a "fixing body" oriented towards the first barrel, to which several modules can be directly attached and which can, if applicable, be oriented towards the first barrel or towards one another. In this way, longer chains of tolerance between the first barrel and the modules, or between the modules themselves, are avoided.
The use of the anchoring element in accordance with the invention has, as a rule, effects on the overall design of the firearm system, since it is -- as will become evident later -advantageous if the individual modules are positioned in a manner suitable for connection with the anchoring element. Thus, the invention is, in addition to the anchoring element, also directed to a firearm system with such an anchoring element.
In individual terms, the invention in accordance with claim 1 details an anchoring element for a firearm system of DE 25 31 620 A, in which at least one additional mounting guide, to which ['fnounting guide] or which [mounting guides] an additional module is attachable, is provided, and the relative position of which to the first barrel is determined or can be determined.
The solution in accordance with the invention thereby has the advantage that, as a rule, it is sufficient, for a precise adjustability of the individual modules, to only manufacture the anchoring element (and not entire parts of the weapon casing) with corresponding precision. The expense for manufacturing and other costs is thereby comparatively lower.
In regard to the function of the anchoring element, it should be clarified yet again that this connects at least two modules with the barrel by way of the mounting guide(s).
It is therefore necessarily designed in a "multi functional" manner, and thereby goes far beyond the function of known solutions, such as of the telescopic sight mount described above, for example.
Nevertheless, the applicant additionally reserves independent protection to itself for an anchoring element in accordance with claim 1 which is, however, oriented towards a military firearm system with at least one module. In addition, the applicant also reserves protection for such an anchoring element with one or more characteristics of the claims 2 to 10 listed in the following.
The anchoring element is (in accordance with claim 2) preferably configured in such a manner that it can be connected, by way of the mounting guide(s), with at least two of the following modules:
~ At least one optical aiming device, preferably to a computer-supported fire control device and/or a necessary sighting device;
An add-on firearm, such as a rapid-fire gun or a grenade-thrower add-on device, for example;
An adjustment device, preferably of a 2-axis adjustment unit, by means of which an additional module for the first barrel, for example, can be adjusted;
-- At least one part of the weapon casing;
-- Means for carrying the weapon, such as a carrying strap or a support grip, for example; andlor:
-- At least one part of the breech or of the breech guide unit.
It proceeds from this that the individual mounting guides can be designed very differently, depending on which modules they are each to be connected with and the level of precision that is required for the connection. The term "mounting guide" thus comprises every type of connecting element, such as mounts, guide units, or bracing supports.

for fitting-, snapping-, or clamping connections, or even simple attachment borings. In this, it is not absolutely necessary for the mounting guide to support the specific module alone.
Rather, the module in question can additionally be supported on another part of the firearm system.
The anchoring element is, in accordance with the invention, connected with the first barrel by way of the connecting part. This does not necessarily mean that the relative positions of anchoring element and barrel are completely fixed. Rather, it is sufficient if the position of the anchoring element is fixed at least in relation to one axis of the barrel, which is generally the axis of the bore.
In one preferred configuration (in accordance with claim 3), the anchoring element can be connected, by way of its connecting part, with a mounting cylinder supporting the first barrel or another part of the firearm system, such as the weapon casing, for example. The anchoring element and the mounting cylinder can thereby also be combined into an integral component. Such an arrangement is, in particular, sensible in those cases in which the first barrel should be partially movable relative to the anchoring element, such as for the purpose of damping a recoil, for example. The barrel is, in that case, supported' in a movable manner inside the mounting cylinder in the direction of its axis of the bore.
In one additional preferred configuration (in accordance with claim 4), the anchoring element can be directly connected with the first barrel by way of its connecting part. A
relative movement between the barrel and anchoring element is also possible in this arrangement by means of corresponding constructive measures. The advantage here is that, because of the direct connection, intermediate parts (such as the said mounting cylinder) are excluded, as the result of which the chain of tolerance between the anchoring element and the barrel is shortened, and the precision of the connection can be increased still further.
_7_ In one additional configuration (in accordance with claim 5), the anchoring element is configured in such a manner that it can be positioned on the forward part of the barrel. A
positioning in this area is frequently advantageous for constructive reasons, particularly if parts of the weapon casing or movable breech parts make an attaching of the anchoring element to the rear part of the barrel difficult. In order to attach an optical aiming device, the mounting guide concerned must, if applicable (in the event of the anchoring element being positioned too far forward), be extended to the rear, such as by means of an extension bar proceeding to the rear, for example. This aiming device is, when the weapon is assembled in an orderly manner, thereby located in the correct position.
Another possibility consists of attaching the optical aiming device with its forward end on the anchoring element and the rear end only in the event of need, that is to say, in the event that the attachment to the front does not suffice to additionally connect with the weapon casing or another part of the firearm system.
In a firearm system in the bull pup method of construction, the magazine, and thereby the closing position of the breech, are placed behind the trigger, instead of in front of the same. The central installation is thus, for the reasons stated above, generally simpler in such a "bull pup". Thus, the firearm system is (in accordance with claim 10) preferably formed as a bull pup.
From what has been said above, it is evident that the anchoring element is, as a rule, connected with modules that are positioned outside of the weapon casing, or which at least project out from this. These modules are, upon the use of the weapon, particularly during use in combat, frequently subjected to impacts and other high forces which are caused, for example, by the maneuvering of the gun in open country. The anchoring element is thus (in accordance with claim 6) preferably configured in such a manner that it can absorb such forces. The forces that appear are transferred by the anchoring element through its connection with the first barrel into the interior of the weapon preferably on supporting parts, that is to say, parts which are correspondingly stressable. In this manner, the force introduced is distributed in the interior of the weapon. On the one hand, the weapon casing is balanced by that means, so that it can be designed to be correspondingly lighter and more favorable in terms of cost. On the other hand, a damaging of less sturdy parts in the interior of the weapon is avoided.
In an additional configuration (in accordance with claim 7), the anchoring element is produced from a one-part block of material and is preferably milled out from this. The advantage of this configuration particularly lies, in addition to technical manufacturing reasons, in an increased sturdiness relative to the forces arising during the use of the weapon which have already been discussed. For the same reasons, the anchoring element is, in an additional configuration (in accordance with claim 8), produced from a metallic alloy, preferably from an aluminum alloy, in order to save weight.
The anchoring element can, alternatively to this, also be manufactured by means of other processes, such as injection molding or casting, and/or from other materials, such as from plastic.
In one further configuration (in accordance with claim 9), the firearm system is developed as a semi- or fully-automatic hand-held firearm. The firearm system can, in an alternate manner, also be developed as a single-loader.
The above statements for the anchoring element are also applicable, in regard to their entire content, to the firearm system in accordance with the invention in accordance with claim 11, namely; a firearm system with a first barrel and a second barrel as a module (structural- and/or add-on element), optionally a weapon casing, and an anchoring element, in accordance with one of the claims 1 to 10.
_g_ The invention will now be illustrated in further detail by means of one example of implementation, as well as the diagrams attached by way of example. The diagrams depict the following:
Figure 1: A cut-away side view from the left of an anchoring element in accordance with the invention, with necessary front sight deployed, a mounting cylinder, and the 2-axis adjustment unit;
Figure 2: An isolated rear view (not to scale) of the anchoring element from Figure 1;
Figure 3: A view from above of the section III-III from Figure 2;
Figure 4: A frontal view of the section IV-IV from Figure 3.
Figure 1 depicts an anchoring element ( 1 ) in accordance with the invention, for a partially depicted firearm (3). The direction of shooting of the firearm (3) is indicated by the arrow (5). This firearm (3) involves a combination of large-caliber semi-automatic rifle and add-on rapid ire gun with a trigger device in common, the barrels of which are supposed to be adjustable to one another. The first barrel, in this case, the barrel of the large-caliber semi-automatic rifle (not depicted), is supported, in a manner free of clearance, in an intermediate casing (7) serving as a mounting cylinder, which [intermediate casing] is solidly connected with the weapon casing. The support bearing of the intermediate casing (7) permits a longitudinal movement of this barrel during the shooting process. The second barrel, in this case, the barrel of the add-on rapid fire gun (not depicted), is connected with a 2-axis adjustment unit (9), by means of which this can be adjusted in its position relative to the first barrel.
The anchoring element (1 ) has an upper part (1-[a]) as well as a lower component (1-[b]) configured in a ring shape (see Figure 2 or 4), which wilt be referred to in the following as the "connecting ring". A necessary front sight (13), which is secured in its position, in a rotatably supported manner, by means of a pin (15), and a bolt (17) which is spring-stressed (spring not depicted), are attached in the upper part (1-[a]). The necessary front sight (13) can thus be folded over from the deployed position that is depicted into an essentially horizontal resting position. The anchoring element (1 ) is supported in a clearance free and rotatable manner on the intermediate casing (7) and is connected with this, by way of a first key / slot connection ( 11 ), in such a manner that it is secured against twisting.
The 2-axis adjustment unit (9) is supported, next to the anchoring element (1 ), on the intermediate casing (7). An adjustment element (9-[aj) of the 2-axis adjustment unit (9) is connected, by means of a second key 1 slot connection (19), with the anchoring element (1 ) and thereby secured against twisting (for the purpose of adjusting, it thereby remains displaceable in the vertical direction).
1t can be seen from Figure 2 that the upper part (1-[a]) has a dovetail guide unit (21) on the upper side in the longitudinal direction. This serves as a universal interface for the accommodation of different add-on devices, particularly of optical aiming devices. The upper part (1-[a]) additionally has two blind borings (23-[a] and 23-[b]) (see also Figure 3) which serve for the accommodation of two closing spring rods, which are not depicted.
These are part of the breech guide unit of the large-caliber semi-automatic rifle and are supported, in the installed condition, with their forward end in the blind borings (23-[a], -[b]), while their rears ends are supported on the weapon casing.
The connecting ring (1-[b]) has two carrier bars (25-[a] and 25-[b]) extending essentially horizontally which, in the installed condition of the anchoring element ( 1 ), project out over the weapon casing on either the left side or the right side of the weapon. it can be seen in Figure 3 (or also Figure 4) that the carrier bars (25-[a], -[b]) have loop-shaped cross-borings (27-[a] or 27-[b]). These serve for the attachment of a carrying strap for carrying the firearm (3). The carrier bars (25-[a], -[b]) have, in addition, two shoulders (29-[a] or 29-[b]) projecting at a height (see Figure 2), which form the counterpart to a snap connection of a part of the weapon casing, which is not depicted. This part of the housing, which serves as a protective covering for the 2-axis adjustment unit, is, for the attachment to the anchoring element (1 ), placed onto the carrier bars (25-[a], -[b]) from the front side of the firearm (3). Correspondingly molded elastic side parts of the housing part are thereby clicked into the shoulders (29-[a], -[b]) from the internal side. The housing part is thereby secured in its inserted position and can thereby be removed from the gun again without the use of a tool in the event of need, such as for the operation of the 2-axis adjustment unit.
Figure 4 shows, finally, that the upper part (1-[a]) is, towards the front, divided into two bars ( 1-[a'] and 1-[a"]), by means of which the upper part ( 1-[a]) is connected with the connecting ring (1-[b]). The bars (1-[a'] and 1-[a"]) define a hollow space (31 ) between themselves, which space serves for the accommodation of the necessary front sight (13) in the installed condition (not depicted). The pin (15) of.the necessary front sight (13) is, in that case, supported in penetrating borings (33-[a] and 33-[b]) of the bars (1-[a'] or 1-[a"]).
In summary, it is to be seen that the present anchoring element ( 1 ) fulfills a total of six functions. It serves:
1. As a suspension unit for the necessary front sight and the engaging of the same;
2. For the accommodation of various add-on devices, particularly of optical aiming devices;
The invention relates to an anchoring element for a firearm system, as well as to a firearm system with such an anchoring element.

The above statements for the anchoring element are also applicable, in regard to their entire content, to the firearm system in accordance with the invention in accordance with claim 11, namely; a firearm system with a first barrel and a second barrel as a module (structural- and/or add-on element), optionally a weapon casing, and an anchoring element, in accordance with one of the claims 1 to 10.
_g_ The invention will now be illustrated in further detail by means of one example of implementation, as well as the diagrams attached by way of example. The diagrams depict the following:
Figure 1: A cut-away side view from the left of an anchoring element in accordance with the invention, with necessary front sight deployed, a mounting cylinder, and the 2-axis adjustment unit;
Figure 2: An isolated rear view (not to scale) of the anchoring element from Figure 1;
Figure 3: A view from above of the section III-III from Figure 2;
Figure 4: A frontal view of the section IV-IV from Figure 3.
Figure 1 depicts an anchoring element ( 1 ) in accordance with the invention, for a partially depicted firearm (3). The direction of shooting of the firearm (3) is indicated by the arrow (5). This firearm (3) involves a combination of large-caliber semi-automatic rifle and add-on rapid ire gun with a trigger device in common, the barrels of which are supposed to be adjustable to one another. The first barrel, in this case, the barrel of the large-caliber semi-automatic rifle (not depicted), is supported, in a manner free of clearance, in an intermediate casing (7) serving as a mounting cylinder, which [intermediate casing] is solidly connected with the weapon casing. The support bearing of the intermediate casing (7) permits a longitudinal movement of this barrel during the shooting process. The second barrel, in this case, the barrel of the add-on rapid fire gun (not depicted), is connected with a 2-axis adjustment unit (9), by means of which this can be adjusted in its position relative to the first barrel.
The anchoring element (1 ) has an upper part (1-[a]) as well as a lower component (1-[b]) configured in a ring shape (see Figure 2 or 4), which wilt be referred to in the following as the "connecting ring". A necessary front sight (13), which is secured in its position, in a rotatably supported manner, by means of a pin (15), and a bolt (17) which is spring-stressed (spring not depicted), are attached in the upper part (1-[a]). The necessary front sight (13) can thus be folded over from the deployed position that is depicted into an essentially horizontal resting position. The anchoring element (1 ) is supported in a clearance free and rotatable manner on the intermediate casing (7) and is connected with this, by way of a first key / slot connection ( 11 ), in such a manner that it is secured against twisting.
The 2-axis adjustment unit (9) is supported, next to the anchoring element (1 ), on the intermediate casing (7). An adjustment element (9-[aj) of the 2-axis adjustment unit (9) is connected, by means of a second key 1 slot connection (19), with the anchoring element (1 ) and thereby secured against twisting (for the purpose of adjusting, it thereby remains displaceable in the vertical direction).
1t can be seen from Figure 2 that the upper part (1-[a]) has a dovetail guide unit (21) on the upper side in the longitudinal direction. This serves as a universal interface for the accommodation of different add-on devices, particularly of optical aiming devices. The upper part (1-[a]) additionally has two blind borings (23-[a] and 23-[b]) (see also Figure 3) which serve for the accommodation of two closing spring rods, which are not depicted.
These are part of the breech guide unit of the large-caliber semi-automatic rifle and are supported, in the installed condition, with their forward end in the blind borings (23-[a], -[b]), while their rears ends are supported on the weapon casing.
The connecting ring (1-[b]) has two carrier bars (25-[a] and 25-[b]) extending essentially horizontally which, in the installed condition of the anchoring element ( 1 ), project out over the weapon casing on either the left side or the right side of the weapon. it can be seen in Figure 3 (or also Figure 4) that the carrier bars (25-[a], -[b]) have loop-shaped cross-borings (27-[a] or 27-[b]). These serve for the attachment of a carrying strap for carrying the firearm (3). The carrier bars (25-[a], -[b]) have, in addition, two shoulders (29-[a] or 29-[b]) projecting at a height (see Figure 2), which form the counterpart to a snap connection of a part of the weapon casing, which is not depicted. This part of the housing, which serves as a protective covering for the 2-axis adjustment unit, is, for the attachment to the anchoring element (1 ), placed onto the carrier bars (25-[a], -[b]) from the front side of the firearm (3). Correspondingly molded elastic side parts of the housing part are thereby clicked into the shoulders (29-[a], -[b]) from the internal side. The housing part is thereby secured in its inserted position and can thereby be removed from the gun again without the use of a tool in the event of need, such as for the operation of the 2-axis adjustment unit.
Figure 4 shows, finally, that the upper part (1-[a]) is, towards the front, divided into two bars ( 1-[a'] and 1-[a"]), by means of which the upper part ( 1-[a]) is connected with the connecting ring (1-[b]). The bars (1-[a'] and 1-[a"]) define a hollow space (31 ) between themselves, which space serves for the accommodation of the necessary front sight (13) in the installed condition (not depicted). The pin (15) of.the necessary front sight (13) is, in that case, supported in penetrating borings (33-[a] and 33-[b]) of the bars (1-[a'] or 1-[a"]).
In summary, it is to be seen that the present anchoring element ( 1 ) fulfills a total of six functions. It serves:
1. As a suspension unit for the necessary front sight and the engaging of the same;
2. For the accommodation of various add-on devices, particularly of optical aiming devices;
3. As a mount for a carrying strap;
4. For the securing of a housing part serving as a cover;
5. As part of the guide unit for the 2-axis adjustment unit of the add-on rapid-fire gun;
6. As a bracing support for both of the closing spring rods.
The anchoring element (1 ) thereby consists of an aluminum alloy and is produced from a one-part block of material by means of milling out. It thereby has both a high precision of shape as welt as also a high stability.
By means of this special configuration of the anchoring element (1 ) and a clearance free bearing support on the intermediate casing (7), a precise adjustment of the optical aiming devices which can be attached to the dovetail on the first barrel is possible.
Because of the relatively short length of the dovetail guide unit, larger aiming device, such as a night vision device or a computer-controlled fire control device, for example, can be attached to the firearm (3) in such a manner that it is suspended on the anchoring element (1 ) at the one end, and on the rear part of the weapon casing at the other end. Practice tests have also shown that such a partial attachment to the anchoring element is sufficient to guarantee a precise shooting pattern.
As has already been described, the intermediate casing (7) is, in the present example, positioned between the anchoring element (1 ) and the first barrel. It is entirely possible, however, to attach the anchoring element (1 ) directly with the first barrel by means of a constructive modification and to position it next to the intermediate casing (7) (this will, if necessary, be interrupted, at the corresponding spot, by the anchoring element [1 ]). In the present example, however, such a solution will be dispensed with for technical manufacturing reasons.
In addition to the improvement of the precision of shooting, the anchoring element (1 ) brings the advantage that the weapon casing can be designed to be relatively light and cost favorable in its construction. The reason for this is that the forces normally acting on the weapon casing are supported almost exclusively by the anchoring element.
Thus, impacts and similar forces that are, upon the use of the weapon, exerted on the add-on device, or, in particular, on the carrier bars (25-[a], -[b]), are guided by the anchoring element (1 ) into the interior of the weapon. These forces are then transferred to supporting parts of the firearm (3), such as the intermediate casing (7) and the first barrel, for example, and distributed over a large surface in this way. A damaging of the weapon casing, as well as of other parts of the firearm (3), is thereby effectively prevented, and the weapon is, on the whole, sturdier.
The anchoring element (1 ) thereby consists of an aluminum alloy and is produced from a one-part block of material by means of milling out. It thereby has both a high precision of shape as welt as also a high stability.
By means of this special configuration of the anchoring element (1 ) and a clearance free bearing support on the intermediate casing (7), a precise adjustment of the optical aiming devices which can be attached to the dovetail on the first barrel is possible.
