Description

Die Erfindung betrifft eine Rückstoßdämpfvorrichtung, welche an eine Handfeuerwaffe anbringbar ist und/oder welche an einer Handfeuerwaffe angebracht ist.The invention relates to a recoil damping device, which is attachable to a handgun and / or which is attached to a handgun.

Bei Handfeuerwaffen treten bei Schußabgabe i. A. erhebliche Rückstoßkräfte auf. Durch diese wird die Waffe entgegen der Schußrichtung, d.h. zum Körper des Schützen hin beschleunigt. Dies kann dazu führen, daß die Waffe gegen den Körper des Schützen stößt, was starke Schmerzen verursacht. Um dies zu verhindern, drückt der Schütze die Waffe beim Anlegen fest gegen seinen Körper, insbesondere seine Schulter.For handguns occur in firing i. A. significant Recoil forces on. Through this the weapon is going against the weft direction, i. towards the shooter's body accelerated. This can cause the weapon against hits the shooter's body, causing severe pain. To prevent this, the shooter presses the Weapon when mooring firmly against his body, in particular his shoulder.

Um die beim Rückstoß auf den Körper des Schützen wirkenden Kräfte zu verringern, ist vorgeschlagen worden, das Waffengehäuse mit einer Dämpfvorrichtung zu versehen. Diese liegt beim Anlegen der Waffe zwischen dem Körper des Schützen, und dem Waffengehäuse, und absorbiert einen Teil der beim Rückstoß frei werdenden Energie.To those who act on the body of the shooter during the recoil Reducing forces has been suggested To provide weapon housing with a damping device. This is when you put the weapon between the body of the shooter, and the weapon housing, and absorbs one Part of the energy released during the recoil.

Beispielsweise ist die in der DE-T2 694 04 180 beschriebene Rückstoß-Dämpfvorrichtung in Form einer Tasche ausgebildet, die an dem Schulterstück eines Gewehrs angebracht ist. Die Tasche besteht aus einem Material, welches nicht oder nur wenig dehnbar ist, z.B. aus Stoff, und ist mit viskoelastischem Gummi gefüllt.For example, that described in DE-T2 694 04 180 Recoil damping device in the form of a pocket, attached to the shoulder piece of a rifle is. The bag is made of a material which not or only slightly extensible, e.g. made of fabric, and is filled with viscoelastic rubber.

Aus der US 4,683,671 ist eine Rückstoß-Dämpfvorrichtung bekannt, welche an einem Gewehr befestigt ist, und welche einen elastischen Außenmantel umfaßt, der einen im wesentlichen rechteckförmigen Querschnitt aufweist. Der Außenmantel ist mit einem Schockabsorbtionsmaterial gefüllt. From US 4,683,671 is a recoil damping device known, which is attached to a rifle, and which an elastic outer jacket comprising a substantially having rectangular cross-section. The outer jacket is filled with a shock absorbing material.

Die FR 2 167 317 zeigt besonders in Fig. 10 einen Rück-Stoßdämpfer für einen Gewehrschaft, mit einer Gummikappe, in der Aussparungen beim Schuß eine Nachgiebigkeit in Schußrichtung veranlassen. Die zusammenhängende Auflagefläche auf der Schulter des Schützen, die Wirkfläche, vergrößert sich dabei kaum.FR 2 167 317 shows, particularly in FIG. 10, a rear shock absorber for a rifle stock, with a rubber cap, in the recesses in the shot a yielding in To initiate weft direction. The coherent contact surface on the shooter's shoulder, the effective area, hardly enlarges.

Das gleiche gilt für die US 2 438 142, die einen Rückstoßdämpfer für einen Gewehrsehaft gemäß dem Oberbegrift des Ansprüchs 1 zeigt, bei der der Rückstoßdämpfer von einem Luftkissen gebildet ist, das jedoch von einer steifen Hülse umgeben ist, die die Vergrößerung der Wirkfläche eng begrenzt. The same applies to US Pat. No. 2,438,142 which discloses a recoil damper for rifle sticking according to US Pat Oberbegrift of Ansprüchs 1 shows, in which the recoil damper formed by an air cushion, however surrounded by a stiff sleeve, which is the enlargement the effective area is limited.

Die Erfindung hat sich zum Ziel gesetzt, die bekannten Rückstoß-Dämpfvorrichtungen weiterzuentwickeln.The invention has set itself the goal of the known To develop recoil damping devices.

Sie erreicht dieses Ziel durch den Gegenstand des Anspruchs 1. Demnach ist eine Rückstoß-Dämpfvorrichtung, welche an eine Handfeuerwaffe anbringbar ist, so ausgestaltet, daß sich deren Wirkfläche - zwischen einem ersten Zustand der Vorrichtung, bei welchem diese beim Anlegen der Waffe gegen den Körper eines Schützen gedrückt wird, und einem zweiten Zustand bei Schußabgabe - stark vergrößert.It achieves this goal through the subject-matter of the claim 1. Accordingly, a recoil damping device is which can be attached to a handgun, designed, that their effective area - between a first State of the device in which this when applying the weapon pressed against the body of a shooter becomes, and a second state at firing - strong increased.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen definiert.Advantageous embodiments of the invention are in the Subclaims defined.

Unter dem Begriff "Wirkfläche" wird hier allgemein der beim Anlegen der Waffe, und anschließender Schußabgabe den Körper des Schützen berührende Teil der Außenfläche der Rückstoß-Dämpfvorrichtung verstanden, insbesondere der Flächenteil, über welchen die Rückstoßkräfte von der Dämpfvorrichtung aus in den Körper des Schützen geleitet werden.The term "effective area" is here generally the when creating the weapon, and then firing the shooter's body touching part of the outer surface the recoil damping device understood, in particular the surface part over which the recoil forces of the Damping device directed into the body of the shooter become.

Beispielsweise kann die Wirkfläche derjenige Teil der Dämpfvorrichtungsfläche sein, der beim Anlegen und anschließender Schußabgabe die Schulter, die Wange oder den Oberarm des Schützen berührt (z.B. dann, wenn die Vorrichtung am Schulterstück eines Gewehrs angebracht ist). Denkbar ist z.B. auch, daß die Wirkfläche derjenige Teil der Außenfläche der Vorrichtung ist, welcher die Handinnenfläche des Schützen berührt (z.B. dann, wenn die Vorrichtung am Griff einer Pistole angebracht ist).For example, the effective area of that part of the Dämpfvorrichtungsfläche be that when creating and then Firing the shoulder, cheek or the Touched the shooter's upper arm (e.g., when the device attached to the shoulder piece of a rifle). It is conceivable, e.g. also, that the effective area of that part the outer surface of the device is which the palm of the hand touched by the shooter (e.g., when the device attached to the handle of a pistol).

Die Erfindung beruht auf folgendem Grundgedanken: Die Dämpfvorrichtung ist so ausgestaltet, daß sich deren Wirkfläche - zwischen einem ersten Zustand der Vorrichtung, bei welchem diese beim Anlegen der Waffe gegen den Körper eines Schützen gedrückt wird, und einem zweiten Zustand bei Schußabgabe - stark vergrößert. Dadurch wird die bei Schußabgabe auftretende Rückstoßkraft am Körper des Schützen auf eine größere Anlagefläche verteilt. Dies verringert den Druck, der beim Rückstoß auf den Körper ausgeübt wird; die Schußabgabe wird als "angenehmer" bzw. weniger schmerzhaft empfunden. Vorteilhaft ist es, wenn die Rückstoßkraft im wesentlichen gleichmäßig über die gesamte Wirkfläche verteilt auf den Körper des Schützen wirkt.The invention is based on the following basic idea: The Damping device is designed so that their Effective area - between a first state of the device, in which this when applying the weapon against the Body of a shooter is pressed, and a second Condition at firing - greatly increased. This will the repulsive force on the body when firing of the shooter spread over a larger contact surface. This Reduces the pressure on recoil on the body is exercised; the firing is called "more pleasant" felt less painful. It is advantageous if the recoil force substantially uniform over the entire effective area distributed on the body of the shooter acts.

Besonders vorteilhaft ist die Dämpfvorrichtung so ausgestaltet, daß sich deren Wirkfläche um mehr als 15%, insbesondere um mehr als 25%, besonders bevorzugt um mehr als 35%, oder um mehr als 50% oder 75% vergrößert. Durch die besonders starke Vergrößerung der Wirkfläche wird ein im besonderen Maß verringerter Rückstoßdruck erreicht.Particularly advantageously, the damping device is designed such that their effective area by more than 15%, in particular by more than 25%, more preferably by more as 35%, or increased by more than 50% or 75%. By the particularly large increase in the effective area is a in particular reduced recoil pressure achieved.

Die Vorrichtung kann z.B. integral ausgebildet sein, und beispielsweise aus einem elastischen Werkstoff bestehen.The device may e.g. be integrally formed, and for example, consist of an elastic material.

Besonders vorteilhaft weist die Vorrichtung einen Außenmantel auf. Dieser besteht bevorzugt aus einem elastischen Material. Besonders vorteilhaft ist der Außenmantel aus einem Elastomer gefertigt, d.h. einem Stoff mit gummiartiger Elastizität, wie beispielsweise Naturkautschuk, Chlorkautschuk, Polybutadien, Polyurethane, oder Silikonkautschuk. Elastomere strecken sich bei starkem Zug bis auf mehr als das Doppelte der anfänglichen Länge. Bei großer Dehnung besitzen sie eine hohe Zugfestigkeit und Steifheit, und nehmen nach Beanspruchung ihre ursprüngliche Form wieder an. Bevorzugt ist der erfindungsgemäße Außenmantel der Dämpvorrichtung so ausgestaltet, daß er sich bei Schußabgabe um mehr als 15%, besonders vorteilhaft um mehr als 30% oder 50% streckt. Particularly advantageously, the device has an outer jacket on. This is preferably made of an elastic Material. Particularly advantageous is the outer jacket made of an elastomer, i. a fabric with rubbery Elasticity, such as natural rubber, Chlorinated rubber, polybutadiene, polyurethanes, or silicone rubber. Elastomers stretch during strong pull until more than twice the initial length. at they have a high tensile strength and great elongation Stiffness, and take their original after stress Shape again. Preferably, the inventive Outer jacket of Dämpvorrichtung designed so that he in the case of a firing fee of more than 15%, especially advantageous stretches by more than 30% or 50%.

Bevorzugt ist der Außenmantel mit einem stoßabsorbierenden Werkstoff gefüllt. Dieser wandelt einen Teil der Rückstoßenergie in Wärme um. Als Stoßabsorptionswerkstoff kann ein Elastomer, z.B. Gummi verwendet werden, beispielsweise in kompakter, oder in nichtkompakter Form (z.B. aufgeschäumt, oder mit einer wabenartigen Struktur versehen). Vorteilhaft ist der Außenmantel mit einer Vielzahl kleiner Absorptionselemente z.B. aus Gummi gefüllt, die sich bei Schußabgabe relativ zueinander verschieben.Preferably, the outer jacket with a shock absorbing Material filled. This converts a part of Recoil energy into heat. As impact absorption material For example, an elastomer, e.g. Rubber can be used, for example in compact or non-compact form (e.g., foamed or with a honeycomb structure Mistake). The outer jacket is advantageous with a Variety of small absorption elements e.g. filled out of rubber, which move relative to each other at firing.

Die Rückstoß-Dämpfvorrichtung kann an einer Handfeurwaffe, z.B. einem Gewehr, einem Maschinengewehr, einer Pistole, oder einer Maschinenpistole angebracht sein. Vorteilhaft ist die Vorrichtung z.B. bei einem Gewehr an dessen Schulterstück, oder z.B. bei einer Pistole an deren Griff befestigt.The recoil damping device can be attached to a handgun, e.g. a rifle, a machine gun, a pistol, or a submachine gun. Advantageous if the device is e.g. at a rifle its shoulder piece, or e.g. at a gun at the Handle attached.

Besonders vorteilhaft weist die Rückstoß-Dämpfvorrichtung ein Trägerelement auf, mit dessen Hilfe die Vorrichtung an der Handfeuerwaffe angebracht ist. Vorzugsweise ist die Verbindung zwischen Waffe und Vorrichtung, insbesondere zwischen Waffe und Trägerelement, lösbar. Die lösbare Verbindung kann z.B. als Rastverbindung ausgestaltet sein. Beispielsweise kann die Dämpfvorrichtung so ausgebildet sein, daß sie jeweils an einer von mehreren, identischen Handfeuerwaffen angebracht werden kann. Vorteilhaft ist eine Ausgestaltung, bei der die Vorrichtung an jeweils einer von mehreren Handfeuerwaffen verschiedenen Typs angebracht werden kann, z.B. an verschiedenen Gewehren.Particularly advantageous, the recoil damping device a support element, by means of which the device attached to the handgun. Preferably the connection between weapon and device, in particular between the weapon and the carrier element, detachable. The detachable Compound can e.g. designed as a latching connection be. For example, the damping device may be formed be that they each at one of several, identical Handguns can be attached. Advantageous is an embodiment in which the device to each one of several handguns different Type can be attached, e.g. on different rifles.

Bei einer alternativen Ausgestaltung kann die Dämpfvorrichtung auch unlösbar mit der Waffe gekoppelt, z.B. mit dieser verschweißt oder vernietet sein. In an alternative embodiment, the damping device also indissolubly coupled to the weapon, e.g. With this welded or riveted.

Dann legt der Schütze das Gewehr an, und drückt dabei die Dämpfvorrichtung 1 fest nach hinten gegen seine Schulter 7, d.h. in Richtung eines Pfeils P. Hierbei wird der Elastomermantel 4a, und das Stoßabsorptionselement 4b leicht verformt. Das Dämpfelement 4 hat dann eine Länge 1 von ca. 5cm, und die hintere Endfläche 4a' des Dämpfelements 4 paßt sich ergonomisch der vorderen Schulterfläche 7a an.Before the use of the rifle, the damping device becomes 1 on the rear end surface 2a of the rifle shoulder piece 2 snapped on, i. firmly connected to the rifle (Fig.2), namely by means of a (not shown) locking connection. Then the shooter puts the rifle on and pushes while the damping device 1 firmly backwards against his Shoulder 7, i. in the direction of an arrow P. This is the elastomer sheath 4a, and the shock absorbing member 4b slightly deformed. The damping element 4 then has a length of 1 of about 5cm, and the rear end surface 4a 'of the damping element 4 fits ergonomically the front shoulder surface 7a on.

Beim Anlegen des Gewehrs hat die Wirkfläche 8, d.h. hier: der die vordere Schulterfläche 7a des Schützen berührende Teil der Außenfläche des Elastomermantels 4a eine Höhe i von ca. 7 cm, und gemäß Fig. 5 eine Breite c von ca. 3 cm. Die Außenkontur der Wirkfläche 8 ist im wesentlichen oval. Aufgrund der erwähnten ergonomischen Anpassung des Dämpfelements 4 ist die Wirkfläche 8 leicht nach innen hin gewölbt (vgl. Fig. 2).When applying the rifle, the effective area 8, i. here: the touching the front shoulder surface 7a of the shooter Part of the outer surface of the elastomer jacket 4a a height i of about 7 cm, and according to FIG. 5, a width c of about 3 cm. The outer contour of the active surface 8 is substantially oval. Due to the mentioned ergonomic adaptation of the Dämpfelements 4, the effective surface 8 is slightly inward arched (see Fig. 2).

Fig. 3 zeigt die in Fig. 1 und 2 dargestellte Dämpfvorrichtung 1 bei einem dritten Zustand, bei welchem ein Schuß aus dem Gewehr abgegeben wird. Durch die bei Schußabgabe auftretende starke Rückstoßkraft wird die Dämpfvorrichtung 1 in Richtung des Pfeils P - noch wesentlich stärker als beim Anlegen - gegen die Schulter 7 des Schützen gedrückt. Hierbei wird der Elastomermantel 4a, und das Stoßabsorptionselement 4b stark verformt. Das Dämpfelement 4 hat dann lediglich noch eine Länge 1 von ca. 2cm. (Anmerkung: in Fig. 3 ist der Zustand maximaler Verformung des Dämpfelements 4 dargestellt).Fig. 3 shows the damping device shown in Fig. 1 and 2 1 at a third state, in which a Shot is fired from the rifle. By at firing occurring strong recoil force is the damping device 1 in the direction of arrow P - still essential stronger than when putting on - against the shoulder 7 of the Shooters pressed. Here, the elastomeric sheath 4a, and the impact absorbing member 4b is greatly deformed. The Damping element 4 then only has a length 1 of about 2cm. (Note: in Fig. 3, the state is maximum Deformation of the damping element 4 shown).

Durch die Verformung des Dämpfelements 4 werden die folgenden Effekte erzielt: zum einen wird ein Teil der beim Rückstoß auftretenden Energie in Wärme umgewandelt, und dadurch die auf die Schulter 7 des Schützen wirkende Rückstoßkraft verringert.By the deformation of the damping element 4, the following Effects achieved: on the one hand, a part of the Recoil energy is converted into heat, and thereby acting on the shoulder 7 of the shooter Recoil force reduced.

Zum anderen wird die Wirkfläche 8, d.h. hier: der die vordere Schulterfläche 7a des Schützen berührende Teil der Außenfläche des Elastomermantels 4a stark vergrößert. Diese ist dann z.B. deutlich größer als die hintere Endfläche 2a des Gewehrschulterstücks 2. Im vorliegenden Fall hat sie bei Schußabgabe eine Höhe i von ca. 12cm, und gemäß Fig. 6 eine Breite c von ca. 5cm.On the other hand, the effective area 8, i. here: the the front shoulder surface 7a of the shooter touching part the outer surface of the elastomer jacket 4a greatly increased. This is then e.g. significantly larger than the rear end surface 2a of the rifle shoulder piece 2. In the present Case she has a height i of about 12cm when firing, and according to FIG. 6, a width c of about 5 cm.

Die Außenkontur der Wirkfläche 8 bleibt im wesentlichen oval. Wie in Fig. 2 und 3 gezeigt ist, ist die Verformung des Dämpfelements 4 so stark, daß Teile derjenigen Abschnitte der Dämpfelement-Außenfläche, die zunächst nicht nach hinten hin zeigen (d.h. z.B. nach oben bzw. unten oder seitlich), bei Schußabgabe einen Teil der Wirkfläche 8 bilden.The outer contour of the active surface 8 remains substantially oval. As shown in Figs. 2 and 3, the deformation is the damping element 4 so strong that parts of those sections the damper outer surface, not initially towards the rear (i.e., up or down, for example or laterally), at firing a portion of the effective area 8 form.

Gemäß Fig. 3 ist das Dämpfelement 4 so ausgebildet, daß die (nach der Dämpfung durch das Dämpfelement 4 verbleibende) Rückstoßkraft im wesentlichen gleichmäßig über die gesamte Wirkfläche 8 verteilt in die Schulter 7 geleitet wird. Beispielsweise sind die im zentralen Bereich der Wirkfläche 8 auf die vordere Schulterfläche 7a wirkenden Kräfte F2 und F3 im wesentlichen gleich groß wie Kräfte F1 und F4, die im oberen bzw. unteren Endbereich der Wirkfläche 8 auf die vordere Schulterfläche 7a wirken (ähnliches gilt z.B. auch im Hinblick auf nicht dargestellte, in linken bzw. rechten Endbereichen der Wirkfläche 8 auf die Schulter wirkende Kräfte im Vergleich mit den in den übrigen Wirkflächenbereichen wirkenden Kräften) .According to Fig. 3, the damping element 4 is formed so that the (remaining after the damping by the damping element 4) Repulsive force substantially uniform over the entire active surface 8 distributed in the shoulder 7 passed becomes. For example, those in the central area of the Working surface 8 acting on the front shoulder surface 7a Forces F2 and F3 are essentially the same size as forces F1 and F4 in the upper and lower end of the Working surface 8 act on the front shoulder surface 7a (Similarly, for example, with regard to not shown, in left and right end regions of the active surface 8 forces acting on the shoulder compared with the forces acting in the other active surface areas) ,

Durch die Verteilung der Rückstoßkraft auf eine relativ große Wirkfläche 8 wird gegenüber herkömmlichen Gewehren bei Schußabgabe ein deutlich geringerer Druck auf die Schulter des Schützen ausgeübt. By distributing the recoil force to a relative large effective area 8 is compared to conventional rifles at firing a much lower pressure on the Shoulder of the shooter exercised.

Nach Schußabgabe kehrt das Dämpfelement in den in Fig. 2 gezeigten Zustand zurück. Durch einen (nicht dargestellten) Betätigungsmechanismus kann dann bevorzugt vom Schützen die Rastverbindung zwischen Schulterstück 2 und Trägerplatte 3 gelöst werden, und somit die Dämpfvorrichtung 1 vom Gewehr abgenommen werden, um gegebenenfalls ausgetauscht zu werden.After firing, the damping element returns to the position shown in FIG. 2 shown state back. By a (not shown) Actuating mechanism can then be preferred from Protect the locking connection between shoulder piece 2 and Support plate 3 are released, and thus the damping device 1 are removed from the rifle, if necessary to be exchanged.
