Description

Die Erfindung betrifft eine Vorrichtung zur Verbindung eines Zusatzgerätes, beispielsweise eines Schalldämpfers, mit dem Lauf einer Waffe, entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a device for connecting an accessory, such as a muffler, with the barrel of a weapon, according to the preamble of claim 1.

Als Stand der Technik im Zusammenhang mit Schalldämpfern können genannt werden: Die US 6,374,718 B, deren Schalldämpfer weit über den Lauf reicht; die GB 2 281 119 A , die einen Schalldämpfer aus Kunststoff zeigt; die US 3,677,132 A die den Schalldämpfer mittels eines abnehmbaren Stoppels auf der Laufseite und mittels eines beim ersten Schuss zerstörten Häutchens auf der Außenseite abdichtet; all diese Verbindungen erfolgen durch Gewinde und Gegengewinde.As state of the art in connection with silencers may be mentioned: The US 6,374,718 B, whose silencer reaches far beyond the barrel; the GB 2 281 119 A showing a plastic muffler; the US 3,677,132 A which seals the silencer on the outside by means of a removable stubble on the running side and by means of a pellet destroyed in the first shot; All these connections are made by thread and counter thread.

Die DE 100 01 374 C beschreibt die Möglichkeit, den an der Waffe befestigten Schalldämpfer um die Laufachse verdrehen und in beliebiger Drehlage fixieren zu können, um eine Fixierung in der Lage vorzunehmen, in der er die Schusseigenschaften der Waffe am wenigsten beeinträchtigt werden. Dazu ist ein Montagesockel vorgesehen, der auf dem Lauf der Waffe angeordnet wird und einen drehbaren Teil aufweist, auf den wiederum der Schalldämpfer aufgesetzt wird; eine extrem aufwendige und schwere Lösung, die erst wiederum Gewinde erfordert.The DE 100 01 374 C describes the possibility of twisting the muffler attached to the weapon about the barrel axis and fix in any rotational position can to make a fix in the position in which he least affected the firing properties of the weapon. For this purpose, a mounting base is provided, which is arranged on the barrel of the weapon and has a rotatable part, on which in turn the muffler is placed; an extremely complex and difficult solution, which requires threading again.

Im Stand der Technik wurden somit derartige Verbindungen stets in Form von Gewinde und Gegengewinde ausgeführt, was wegen der Kosten Herstellung teuer und wegen der Notwendigkeit des genauen Aufsetzens beim Montieren des Zusatzgerätes insbesondere während eines Einsatzes zeitaufwändig ist und stets die Gefahr der Beschädigung des Gewindes mit sich bringt.In the prior art, such compounds were thus always carried out in the form of thread and counter thread, which is expensive because of the cost of manufacturing and time-consuming because of the need for accurate placement when mounting the attachment especially during use and always the risk of damaging the thread with it brings.

Die Erfindung hat somit die Aufgabe, eine robuste und schnell zu bedienende Verbindung zu schaffen.The invention thus has the task of creating a robust and fast-to-use connection.

Erfindungsgemäß wird dies dadurch erreicht, dass die Verbindungsvorrichtung laufseitig aus zumindest einer, bevorzugt zwei einander gegenüberliegenden Abplattungen der äußeren Mantelfläche des Laufes und zumindest einer, bevorzugt zwei einander gegenüberliegenden Nuten, die in einer Normalebene zur Laufachse liegen, besteht, und am Zusatzgerät aus einem, bevorzugt zwei einander gegenüberliegenden, federnd ausgebildeten oder federnd gelagerten Stiften bzw. Plättchen entsprechend den kennzeichnenden Merkmalen des Anspruches 1.According to the invention this is achieved in that the connecting device running side of at least one, preferably two opposing flattenings of the outer surface of the barrel and at least one, preferably two each other opposite grooves, which lie in a normal plane to the barrel axis, consists, and the accessory of one, preferably two opposing, resiliently formed or resiliently mounted pins or plates according to the characterizing features of claim 1.

Die Erfindung ist in der Zeichnung in Form eines Ausführungsbeispieles dargestellt; dabei zeigt

  • die Fig. 1 die Spitze eine Laufes in perspektivischer Ansicht und zwei vergrößerte Seitenansichten und
  • die Fig. 2 einen Schnitt durch eine Verbindungsvorrichtung im eingesteckten Zustand.
The invention is illustrated in the drawing in the form of an embodiment; shows
  • the Fig. 1 the tip of a barrel in perspective view and two enlarged side views and
  • the Fig. 2 a section through a connecting device in the inserted state.

Die in den Fig. 1 und 2 dargestellte, neuartige und nicht nur für Schalldämpfer, sondern auch für andere Zusatzgeräte, die am Lauf einer Waffe befestigt werden, brauchbare Verbindung zwischen dem Lauf einer Waffe und dem Zusatzgerät ist folgendermaßen aufgebaut: Diese Verbindung besteht aus zwei Abplattungen 11 am Außenmantel des Laufes 12 der Waffe und zwei im Winkel, bevorzugt im rechten Winkel dazu angeordneten, gerade im Fleisch (Wandstärke) des Laufes 11 geführte Nuten 13. Dabei liegt die mündungsferne Wand 14 der Nuten 13 im Wesentlichen in derselben Ebene wie das mündungsferne Ende 14' der Abplattungen 11.The in the Fig. 1 and 2 shown, novel and not only for mufflers, but also for other accessories that are attached to the barrel of a weapon, useful connection between the barrel of a weapon and the attachment is constructed as follows: This compound consists of two flattenings 11 on the outer surface of the barrel 12 of Weapon and two at an angle, preferably arranged at right angles thereto, just in the meat (wall thickness) of the barrel 11 guided grooves 13. The mündungsferne wall 14 of the grooves 13 is located substantially in the same plane as the muzzle distal end 14 'of the flattenings eleventh

Das Gegenstück dieser Verbindungskonstruktion ist am aufzusetzenden Gegenstand, hier am Schalldämpfer 15, ausgebildet. Dieses Gegenstück weist zwei federnd ausgebildete oder federnd gelagerte, in einer Normalebene zur Laufachse 6 und symmetrisch zu dieser liegende Stifte 16 oder Plättchen auf. Durch die Federung, beispielsweise ein elastisch deformierbares Plättchen 23, werden die Stifte 16 innerhalb der Normalebene zur Achse 6, zueinander gedrückt.The counterpart of this connection construction is formed on the object to be placed on, here on the silencer 15. This counterpart has two spring-trained or spring-mounted, in a normal plane to the barrel axis 6 and symmetrically to this lying pins 16 or platelets. By the suspension, for example, an elastically deformable plate 23, the pins 16 are pressed within the normal plane to the axis 6 to each other.

Der minimale Abstand der Stifte 16 voneinander ist bevorzugt so groß, dass sie im montierten Zustand des Schalldämpfers federnd am Grund 17 der Nuten 13 anliegen. Ihr Abstand entspricht dem Abstand der Abplattungen am Lauf, was die Montage des Zubehörs 15 ermöglicht bzw. erleichtert. Wesentlicher ist aber, dass in der verriegelten Lage, in der die Stifte 16 in den Nuten 13 liegen, die Stifte so tief in den Nuten liegen, dass sie mit ihrer in Richtung der Laufachse gesehen vordersten und/oder hintersten Erzeugenden an der Nutwand anliegen. Mit anderen Worten: Die Stifte 16 tauchen zumindest mit ihrem halben Durchmesser in die Nuten 13 ein. Wenn statt Stiften mit kreisrundem Querschnitt Plättchen oder Stifte mit anderem Querschnitt verwendet werden, gilt dies mutatis mutandis. Dadurch wird auch beim Auftreten starker Erschütterungen bzw. Vibrationen oder Stöße das Auftreten jeder Kraftkomponente an den Stiften/Plättchen normal zur Laufachse 6 und damit jede Gefahr einer ungewollten Entriegelung der Verbindung verhindert.The minimum distance of the pins 16 from each other is preferably so great that they rest in the mounted state of the muffler resiliently on the base 17 of the grooves 13. Their distance corresponds to the distance of the flattenings on the barrel, which allows or facilitates the installation of the accessory 15. It is more important, however, that in the locked position in which the pins 16 are in the grooves 13, the pins are so deep in the grooves that they with their seen in the direction of the barrel axis foremost and / or rearmost generatrix rest against the groove wall. In other words, the pins 16 dive into the grooves 13 at least with their half diameter. If instead of pins with a circular cross section plates or pins with a different cross section are used, this applies mutatis mutandis. As a result, the occurrence of any force component on the pins / plate normal to the barrel axis 6 and thus any danger of unwanted unlocking of the compound is prevented even when strong shocks or vibrations or shock.

Zur Montage des Zubehörs 15 werden die beiden Teile mit annähernd fluchtenden Achsen und in einer Winkellage, in der die Stifte/Plättchen 16 den Abplattungen 11 gegenüber stehen, ineinander geschoben, bis die Stirnfläche des Zubehörs an der Stirnfläche des Laufs anliegt. In dieser Lage liegen die Stifte/Plättchen 16 an der Schulter bzw. Wand 14' an oder liegen unmittelbar davor. Sodann wird das Zubehör 15 gegenüber dem Lauf 12 um 90° verdreht, was durch die federnde Ausbildung/Lagerung der Stifte/Plättchen 16 möglich ist, bis diese unter bevorzugt teilweiser Entspannung in den Nuten 13 zu liegen kommen, wodurch die Verbindung hergestellt ist.To mount the accessory 15, the two parts with approximately aligned axes and in an angular position in which the pins / plates 16 the flattenings 11 face each other, pushed into each other until the end face of the accessory rests against the end face of the barrel. In this position, the pins / plates 16 are on the shoulder or wall 14 'or lie directly in front of it. Then, the accessory 15 is rotated relative to the barrel 12 by 90 °, which is possible by the resilient training / storage of the pins / plates 16 until they come to rest under preferably partial relaxation in the grooves 13, whereby the connection is made.

Diese erfindungsgemäße Verbindungsvorrichtung zwischen Lauf 12 und Zubehör 15 weist gegenüber den vorbekannten, bisher verwendeten Gewinden mehrere große Vorteile auf: Es ist nicht notwendig, die richtige Lage der beiden Gewinde zueinander zu finden, es ist insbesondere nicht notwendig, die Achse der Waffe mit der Achse des Zubehörs exakt zum Fluchten zu bringen, damit wird auch jede Gefahr einer Beschädigung des Gewindes und damit des Unbrauchbarwerdens des Laufes und/oder des Zubehörteils vermieden.This connecting device according to the invention between barrel 12 and accessories 15 has over the previously known, previously used threads several major advantages: It is not necessary to find the correct position of the two threads to each other, it is particularly not necessary, the axis of the weapon with the axis To bring the accessories exactly to align, so any danger of damage to the thread and thus the unusability of the barrel and / or the accessory is avoided.

Anhand des Beispiels von Schalldämpfern soll noch ausgeführt werden: Praktisch alle vorbekannten Schalldämpfer bestehen wegen der mechanischen und thermischen Beanspruchungen bei ihrer Verwendung aus metallischen Werkstoffen, meist Stahl. Eine wesentliche Eigenschaft eines Schalldämpfers ist seine Masse. Da er am vorderen Ende der Waffe montiert ist, führt seine Masse zu einer Verlagerung des Gesamtschwerpunktes der Waffe und, insbesondere bei Pistolen zu Beeinträchtigungen der Bewegung des Schlittens und damit beim Auswerfen der leeren Patronenhülse und dem Laden der nächsten Patrone. Dazu kommt, dass der Schütze den Schalldämpfer während des Einsatzes mit sich tragen muss. Eine Verringerung der Masse des Schalldämpfers durch möglichst weitgehende Verwendung von Kunststoff ist daher eine weitere Aufgabe der Erfindung.With reference to the example of silencers is still running: Virtually all known silencer exist because of the mechanical and thermal stresses in their use of metallic materials, usually steel. An essential feature of a muffler is its mass. Since it is mounted at the front end of the weapon, its mass leads to a shift of the overall center of gravity of the weapon and, especially in pistols to affect the movement of the carriage and thus when ejecting the empty cartridge case and loading the next cartridge. In addition, the shooter carry the muffler with him during use got to. A reduction of the mass of the muffler by using plastic as far as possible is therefore a further object of the invention.

Wenn metallische Teile verwendet werden, so insbesondere für die Befestigungsvorrichtung für die Befestigung an der Waffe, und gegebenenfalls für Teile der Einbauten. Dadurch wird die Gewichtsersparnis nicht besonders beeinträchtigt und es werden doch die am meisten belasteten Teile - oftmaliges Montieren und Demontieren, direkter Kontakt mit den Explosionsgasen im Bereich des Schusskanals - aus widerstandsfähigem Metall hergestellt. Diese Metallteile werden bevorzugt als "verlorene Kerne" beim Herstellen des Gehäuses vom Kunststoff ummantelt.If metallic parts are used, in particular for the fastening device for attachment to the weapon, and possibly for parts of the internals. As a result, the weight savings are not particularly impaired and yet the most heavily loaded parts - often mounting and demounting, direct contact with the explosion gases in the region of the firing channel - made of durable metal. These metal parts are preferably encased as "lost cores" in the manufacture of the housing of the plastic.

Die verwendeten Materialien kann der Fachmann auf dem Gebiete der Kunststofftechnik in Kenntnis der Anforderungen und Erfindung aus vielen auswählen, als Beispiel seien nur genannt: Thermoplastische Elastomere wie Polypropylen, Polyethylen, Polyolefine, Polyamide, Acetalharze und können faserverstärkt sein oder auch nicht. Als Verstärkung kommen beispielsweise Glasfasern, Kohlefasern oder Keflarfasern in Frage.The materials used can be selected by those skilled in the art of plastics technology with knowledge of the requirements and invention of many, for example: Thermoplastic elastomers such as polypropylene, polyethylene, polyolefins, polyamides, acetal resins and may or may not be fiber-reinforced. As reinforcement, for example, glass fibers, carbon fibers or Keflarfasern in question.
