Definitions
- the invention relates to a ring detonator in a projectile ammunition consisting of a projectile and a sleeve, in particular a rifle cartridge, with a hollow ignition ring receiving an ignition means, the ignition ring having a substantially U-shaped, axially aligned cross-section, the inner leg and preferably the bottom thereof the outer leg are reinforced.
- Firearms or the like arranged laterally next to the loading space or a radially penetrating ignition pin into the loading space. require ammunition equipped with circumferential fuses, as is known from EP-A-255 996. There the circumferential fuse is accommodated in an annular groove in the head part of the sleeve, the inner leg of the annular groove forming a socket for the projectile.
- this known ring igniter can be filled with ignition means only with great difficulty and therefore entails a considerable manufacturing outlay.
- the projectile used in the cartridge case is used as an abutment, whereby a special design of the cartridge case is required to or the like by the firing pin. to be able to actually use the applied ignition energy to squeeze the ignition means and not to make it ineffective due to excessive deformation work.
- this configuration of the abutment depends on the respective cartridge and the positioning of the ring fuse is predetermined, which considerably complicates the adaptation of the ring fuse ammunition to the respective ignition systems of different firearms.
- the invention is therefore based on the object to remedy these deficiencies and to create a ring fuse of the type described, which can be produced rationally, ensures a largely free use of the actual design of the cartridge, and also offers full functional reliability in cartridges with plastic sleeves.
- the invention solves this problem in that the ring fuse is inserted within the sleeve receiving a propellant charge at a distance from the projectile.
- This simple open ignition ring can be manufactured economically and easily filled.
- the ignition ring can be used without a third-party abutment and is suitable for a wide variety of cartridges and ammunition types with or without plastic sleeves, and its position is largely free depending on the ignition system of the associated firearms can be chosen.
- the ignition ring can also be used with its open side in or against the direction of the shot in order to influence the combustion process when igniting and burning off the propellant charge, with the open ignition ring also ensuring immediate and uniform ignition of the propellant charge on the circumference.
- the ignition ring is made of aluminum or an aluminum alloy and the thickness of the inner leg and, if applicable, of the base corresponds approximately to twice the thickness of the outer leg, a resistant, functionally reliable ring igniter results in a particularly economical manner.
- a cartridge 1 has a projectile 2 and a sleeve 4 receiving a propellant charge 3.
- the cartridge 1 is equipped with a ring detonator 5, which consists of an ignition ring 6 with a U-shaped cross section and an ignition means 7 pressed into the cavity of the U-shaped cross section.
- the inner leg 6a and the bottom 6b of the ignition ring 6 are reinforced with respect to the outer leg 6c, so that the inner leg 6a and bottom 6b themselves form the abutment for a squeezing of the ignition means 7 required for ignition by the radial action of an ignition pin.
- the ignition ring 6 is filled in a rational manner outside the sleeve 4 with the ignition means, or the like by a seal.
- the primer filling is closed and thus secured against falling out during assembly or protected against becoming damp and then can usually be inserted into the sleeve 4 mostly with the open side first.
- the axial position of the ring detonator 5 can be freely selected as a function of the ignition system of the associated weapon within the sleeve 4 and, in itself, a corresponding press fit is sufficient for fixing it in position, but also forms of the Sleeve or other spacers for positioning the ring igniter within the sleeve 4 may be provided.

Description
Die Erfindung bezieht sich auf einen Ringzünder in einer aus Geschoß und Hülse bestehenden Schußwaffenmunition, insbesondere Gewehrpatrone, mit einem hohlen, ein Zündmittel aufnehmenden Zündring, wobei der Zündring einen im wesentlichen U-förmigen, axial ausgerichteten querschnitt besitzt, dessen Innenschenkel und vorzugsweise dessen Boden gegenüber dem Außenschenkel verstärkt sind.The invention relates to a ring detonator in a projectile ammunition consisting of a projectile and a sleeve, in particular a rifle cartridge, with a hollow ignition ring receiving an ignition means, the ignition ring having a substantially U-shaped, axially aligned cross-section, the inner leg and preferably the bottom thereof the outer leg are reinforced.
Schußwaffen, die eine seitlich neben dem Laderaum angeordnete Zündeinrichtung bzw. einen radial in den Laderaum eindringenden Zündstift od.dgl. aufweisen, verlangen mit Umfangszündern ausgerüstete Munition, wie sie aus der EP-A-255 996 bekannt ist. Dort ist der Umfangszünder in einer Ringnut im Kopfteil der Hülse untergebracht, wobei der innere Schenkel der Ringnut eine Fassung für das Geschoß bildet.Firearms or the like arranged laterally next to the loading space or a radially penetrating ignition pin into the loading space. require ammunition equipped with circumferential fuses, as is known from EP-A-255 996. There the circumferential fuse is accommodated in an annular groove in the head part of the sleeve, the inner leg of the annular groove forming a socket for the projectile.
Dieser bekannte Ringzünder läßt sich allerdings nur recht umständlich mit Zündmittel füllen und bringt daher einen beträchtlichen Herstellungsaufwand mit sich. Darüber hinaus wird das in der Patronenhülse eingesetzte Geschoß als Widerlager benutzt, wodurch eine spezielle Ausgestaltung der Patronenhülse erforderlich ist, um die durch den Zündstift od.dgl. aufgebrachte Zündenergie auch tatsächlich zum quetschen des Zündmittels nutzen zu können und sie nicht auf Grund zu starker Verformungsarbeiten unwirksam werden zu lassen.However, this known ring igniter can be filled with ignition means only with great difficulty and therefore entails a considerable manufacturing outlay. In addition, the projectile used in the cartridge case is used as an abutment, whereby a special design of the cartridge case is required to or the like by the firing pin. to be able to actually use the applied ignition energy to squeeze the ignition means and not to make it ineffective due to excessive deformation work.
Abgesehen vom damit verbundenen Mehraufwand ist diese Ausbildung des Widerlagers aber von der jeweiligen Patrone abhängig und die Positionierung des Ringzünders ist dadurch vorgegeben, was die Anpassung der Ringzündermunition an die jeweiligen Zündsysteme verschiedener Schußwaffen beträchtlich erschwert.Apart from the additional effort involved, this configuration of the abutment depends on the respective cartridge and the positioning of the ring fuse is predetermined, which considerably complicates the adaptation of the ring fuse ammunition to the respective ignition systems of different firearms.
Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und einen Ringzünder der eingangs geschilderten Art zu schaffen, der rationell herstellbar ist, eine weitgehend von der eigentlichen Ausgestaltung der Patrone freie Einsatzmöglichkeit gewährleistet und auch bei Patronen mit Kunststoffhülsen volle Funktionssicherheit bietet.The invention is therefore based on the object to remedy these deficiencies and to create a ring fuse of the type described, which can be produced rationally, ensures a largely free use of the actual design of the cartridge, and also offers full functional reliability in cartridges with plastic sleeves.
Die Erfindung löst diese Aufgabe dadurch, daß der Ringzünder innerhalb der eine Treibladung aufnehmenden Hülse mit Abstand von dem Geschoß eingesetzt ist. Dieser einfache offene Zündring läßt sich wirtschaftlich fertigen un problemlos befüllen. Er bildet darüber hinaus mit seinem verstärkten Innenschenkel und dem die sich ergebende Steifigkeit weiter erhöhenden verstärkten Boden selbst das für den Zündvorgang erforderliche Widerlager und der verbleibende Außenschenkel, der besonders dünnwandig sein kann, erleichtert dabei zusätzlich die Quetschung des Zündmittels durch einen Zündstift. Der Zündring ist ohne ein fremdes Widerlager einzusetzen und eignet sich für die verschiedensten Patronen und Munitionsarten mit oder ohne Kunststoffhülsen, wobei seine Lage jeweils in Abhängigkeit vom Zündsystem der zugehörigen Schußwaffen in weiten Bereichen frei gewählt werden kann. Auch läßt sich der Zündring mit seiner offenen Seite in oder gegen Schußrichtung einsetzen, um den Verbrennungsvorgang beim Zünden und Abbrennen der Treibladung zu beeinflussen, wobei durch den offenen Zündring auch eine unmittelbare und umfangsseitig gleichmäßige Zündung der Treibladung gewährleistet ist.The invention solves this problem in that the ring fuse is inserted within the sleeve receiving a propellant charge at a distance from the projectile. This simple open ignition ring can be manufactured economically and easily filled. In addition, with its reinforced inner leg and the reinforced bottom, which further increases the resulting rigidity, it itself forms the abutment required for the ignition process and the remaining outer leg, which can be particularly thin-walled, additionally facilitates the squeezing of the ignition means by an ignition pin. The ignition ring can be used without a third-party abutment and is suitable for a wide variety of cartridges and ammunition types with or without plastic sleeves, and its position is largely free depending on the ignition system of the associated firearms can be chosen. The ignition ring can also be used with its open side in or against the direction of the shot in order to influence the combustion process when igniting and burning off the propellant charge, with the open ignition ring also ensuring immediate and uniform ignition of the propellant charge on the circumference.
Besteht der Zündring aus Aluminium bzw. einer Aluminiumlegierung und entspricht die Stärke des Innenschenkels und gegebenenfalls des Bodens etwa der doppelten Stärke des Außenschenkels, ergibt sich auf besonders wirtschaftliche Weise ein widerstandsfähiger, funktionssicherer Ringzünder.If the ignition ring is made of aluminum or an aluminum alloy and the thickness of the inner leg and, if applicable, of the base corresponds approximately to twice the thickness of the outer leg, a resistant, functionally reliable ring igniter results in a particularly economical manner.
In der Zeichnung ist der Erfindungsgegenstand beispielsweise an Hand einer im Axialschnitt dargestellten Patrone mit erfindungsgemäßem Ringzünder veranschaulicht.In the drawing, the subject matter of the invention is illustrated, for example, with the aid of a cartridge shown in axial section with a ring igniter according to the invention.
Eine Patrone 1 weist ein Geschoß 2 und eine eine Treibladung 3 aufnehmende Hülse 4 auf. Die Patrone 1 ist mit einem Ringzünder 5 bestückt, der aus einem im Querschnitt U-förmigen Zündring 6 und einem in den Hohlraum des U-förmigen Querschnittes eingepreßten Zündmittel 7 besteht. Der Innenschenkel 6a und der Boden 6b des Zündringes 6 sind dabei gegenüber dem Außenschenkel 6c verstärkt, so daß Innenschenkel 6a und Boden 6b selbst das Widerlager für ein zum Zünden erforderliches Quetschen des Zündmittels 7 durch die radiale Einwirkung eines Zündstiftes bilden. Der Zündring 6 wird auf rationelle Weise außerhalb der Hülse 4 mit dem Zündmittel befüllt, wobei durch eine Versiegelung od.dgl. die Zündmittelfüllung verschlossen und somit vor einem Herausfallen bei der Montage gesichert oder vor einem Feuchtwerden geschützt und dann einfach meist mit der offenen Seite voran in die Hülse 4 eingesetzt werden kann. Die axiale Lage des Ringzünders 5 läßt sich in Abhängigkeit vom Zündsystem der zugehörigen Waffe innerhalb der Hülse 4 frei wählen und zu seiner Lagefixierung genügt an und für sich ein entsprechender Preßsitz, doch könnten auch Ausformungen der Hülse oder andere Abstandhalter zur Positionierung des Ringzünders innerhalb der Hülse 4 vorgesehen sein.A
