Abstract

A spring closing assembly is disclosed which is adapted to be selectively installed and removed from a firearm. The illustrated spring closing assembly includes a rod having a free forward end which defines a slot dividing the free forward end into fork prongs. The assembly also includes a spring mounted on the rod, and a projecting part located on a first one of the fork prongs. At least the first fork prong is resiliently displaceable in an inward direction. The assembly also includes a washer dimensioned to be forced onto the free end of the rod by inwardly displacing the first fork prong. At least one of the projecting part and the washer is chamfered to promote the inward displacement of the first fork prong. The washer is captured between the projecting part and the spring.</PTEXT>

Description

Baugruppe für Handfeuerwaffen Handgun assembly
Die Erfindung betrifft eine Baugruppe für Handfeuerwaffen, mit: einer Stange mit einem freien Ende, mindestens einem Bauteil, das auf die Stange aufgezogen bzw. aufge- fädelt ist, und einer Halteanordnung, die das Bauteil unverlierbar auf der Stange hält und bei eingebauter Baugruppe unbelastet ist (Oberbegriff des Anspruchs 1) . Es wird in diesem Zusammenhang auf die DE-PS 437 959 verwiesen.The invention relates to an assembly for small arms, comprising: a rod with a free end, at least one component which is pulled or threaded onto the rod, and a holding arrangement which holds the component captively on the rod and is unloaded when the assembly is installed is (preamble of claim 1). In this connection, reference is made to DE-PS 437 959.
Eine derartige Baugruppe muß beim Zerlegen der Handfeuerwaffe ausgebaut werden, soll aber ihrerseits nicht oder vorläufig nicht weiter zerlegt werden; etwa weil dann der erneute Einbau der Baugruppe zu schwierig ist. Üblicher- weise wird eine derartige Baugruppe durch eine Sicherungsscheibe unzerlegbar zusammengehalten, die in eine Ringnut nahe dem freien Ende der Stange eingedrückt ist und dort federnd festsitzt. Solche Sicherungsscheiben sind beispielsweise in der DIN 6799 gezeigt.Such an assembly must be removed when disassembling the handgun, but should not be disassembled, or should not be disassembled for the time being; for example, because then it is too difficult to reinstall the module. Usually, such an assembly is held together by a locking washer, which is pressed into an annular groove near the free end of the rod and rests there resiliently. Such locking washers are shown for example in DIN 6799.
Dabei dienen diese Sicherungsscheiben lediglich dem Zusammenhalt der ausgebauten Baugruppe; bei eingebauter Baugruppe bleiben diese Sicherungsscheiben funktionslos und übernehmen keinerlei Kräfte. Ein besonders typisches Beispiel für eine derartige Baugruppe ist die Schließfedereinrichtung von Selbstladepi- stolen mit Colt-Browning-Verriegelung : Am hinteren Ende einer Feder-Zentrierstange ist ein Raststück fest angebracht. Auf die Stange selbst ist eine wendeiförmige Schließfeder aufgeschoben. Darauf folgt eine ringförmige Feder-Abstützplatte, die hier allgemein als Bauteil bezeichnet ist. Dabei ist die Feder in entlastetem Zustand länger als die Feder-Zentrierstange, so daß der Zusammenbau recht knifflig ist. Um diesen Zusammenbau zu erleichtern, ist im vorderen Ende der Feder-Zentrierstange.eine Ringnut ausgebildet, in der eine Sicherungsscheibe sitzt. Bei ausgebauter Schließfedereinrichtung drückt die leicht zusammengedrückte Schließfeder die Feder-Abstützplatte gegen die Sicherungsscheibe, kann sie aber nicht von der Feder-Zentrierstange herunterschieben. Beim Zusammenbau wird die Schließfedereinrichtung von unten her in den Schlitten der Pistole eingelegt, in der sich bereits der Lauf befindet, leicht nach vorne gedrückt und in den Verriegelungskörper am Ende des Laufes eingerastet. In diesem Einbauzustand ist die Schließfeder ein wenig weiter zusammengedrückt, als vorher, so daß die Sicherungsscheibe entlastet ist.These lock washers only serve to hold the removed assembly together; When the module is installed, these lock washers remain inoperative and do not take on any forces. A particularly typical example of such an assembly is the closing spring device of self-loading pistols with a Colt-Browning lock: A locking piece is firmly attached to the rear end of a spring centering rod. A helical closing spring is pushed onto the rod itself. This is followed by an annular spring support plate, which is generally referred to here as a component. The spring is longer in the unloaded state than the spring centering rod, so that the assembly is quite tricky. To facilitate this assembly, an annular groove is formed in the front end of the spring centering rod, in which a locking washer is located. When the closing spring device is removed, the slightly compressed closing spring presses the spring support plate against the locking washer, but cannot push it down from the spring centering rod. During assembly, the closing spring device is inserted from below into the slide of the pistol, in which the barrel is already located, pushed slightly forward and locked into the locking body at the end of the barrel. In this installed state, the closing spring is compressed a little more than before, so that the locking washer is relieved.
Es hat sich aber gezeigt, daß einige Sicherungsscheiben beim Gebrauch der Waffe zerspringen oder abspringen. Offensichtlich überleben sie Schwingungen nicht, die auf die Feder-Zentrierstange beim Schuß aufgebracht wurden. Die Funktion der Waffe wird dabei in aller Regel nicht beeinträchtigt, aber nach dem nächsten Zerlegen ist der erneute Zusammenbau erheblich erschwert .However, it has been shown that some locking washers crack or come off when using the weapon. Obviously, they do not survive vibrations that were applied to the spring centering rod when it was fired. The function of the weapon is usually not affected, but after the next disassembly, the reassembly is considerably more difficult.
Natürlich wurden die zu Bruch gegangenen oder abgesprun- genen Sicherungsscheiben und die zugehörige Ringnut eingehend untersucht und vermessen, doch ohne Unregelmäßigkeiten zu entdecken. Es wurde daher in Erwägung gezogen, daß der Kunde bei der Waffe die Sicherungsscheibe unsachgemäß entfernt, dabei beschädigt und danach wieder aufge- setzt hatte. Befragungen der Kunden konnten diese Annahme jedoch nicht bestätigen.Of course, the lock washers that broke or cracked and the associated ring groove were examined and measured in detail, but without discovering any irregularities. It was therefore considered that the customer improperly removed the safety washer on the weapon, damaged it and then reinstalled it. had set. However, customer surveys were unable to confirm this assumption.
Es trat ferner eine Häufung von Schadensfällen bei den Sicherungsscheiben spezieller Hersteller auf, ohne daß aber eine vernünftige Verallgemeinerung möglich gewesen wäre, um der Ursache der Schadensfälle auf die Spur zu kommen .There was also an accumulation of damage to the lock washers of special manufacturers, but without a reasonable generalization to find the cause of the damage.
Nun wäre es am einfachsten, ein Beutelchen mit Sicherungsscheiben (ein Pfennigartikel) jeder ausgelieferten Waffe beizupacken. Dies würde aber gewissermaßen ein Eingeständnis bedeuten, daß eine schadhafte oder zumindest noch nicht voll durchkonstruierte, in jedem Fall aber nicht völlig zuverlässige Waffe ausgeliefert wird. Da die Kundschaft aber höchste Zuverlässigkeit fordert, ist diese Vorgehensweise verworfen worden.Now it would be easiest to pack a bag with lock washers (a penny item) with every weapon delivered. To a certain extent, however, this would mean an admission that a defective or at least not yet fully designed, but in any case not completely reliable weapon will be delivered. However, since customers demand the highest level of reliability, this approach has been rejected.
Aufgabe der Erfindung ist es, die eingangs genannte Bau- gruppe dahingehend weiterzubilden, daß sie beim Ausbau sicherer zusammenhält.The object of the invention is to develop the module mentioned at the outset in such a way that it holds together more securely during removal.
Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Anspruchs 1 gelöst, also dadurch, daß in der gat- tungsgemäßen Baugruppe an der Stange mindestens ein abgefederter Vorsprung angeordnet oder ausgebildet ist, der beim Aufschieben des Bauteils au.f die Stange ausweicht, danach wieder in seine Ruhelage zurückkehrt und in dieser bei ausgebauter Baugruppe mit dem Bauteil in rückhalten- den Eingriff tritt.This object is achieved according to the invention by the subject matter of claim 1, that is to say in that at least one spring-loaded projection is arranged or formed on the rod in the generic assembly, which protrudes when the component is slid onto the rod, then back into it Returns to the rest position and engages with the component with the component removed.
In der erfindungsgemäßen Baugruppe werden also die Sicherungsscheibe und die Aufnahmenut weggelassen und an deren Stelle ein Vorsprung angeordnet, der radial nach außen federbelastet ist. In seiner Ruhelage (der radial am weitesten außenliegenden Lage) tritt der entsprechend bemessene und ausgebildete Vorsprung gegebenenfalls in Eingriff mit dem Bauteil, um zu verhindern, daß dieses von der Stange abrutscht. Die Abfederung des Vorsprunges läßt aber zu, daß dieser radial so weit nach innen abgesenkt werden kann, daß das Bauteil über den Vorsprung hinweg auf die Stange oder von dieser herunter geschoben werden kann.In the assembly according to the invention, the locking washer and the receiving groove are therefore omitted and a projection is arranged in their place, which is spring-loaded radially outwards. In its rest position (the radially outermost position), the appropriately sized and formed protrusion may engage the component to prevent it from slipping off the rod. The cushioning of the projection leaves but to the fact that this can be lowered radially inwards so far that the component can be pushed over the projection onto the rod or from it.
Versuche haben die Haltbarkeit der erfindungsgemäßen Baugruppe ergeben, obwohl letztlich nicht genau bekannt wurde, warum die früheren Sicherungsscheiben zerbarsten und jetzt der Vorsprung hält.Tests have shown the durability of the assembly according to the invention, although in the end it was not known exactly why the earlier locking washers burst and why the projection now holds.
Es ist grundsätzlich möglich, den Vorsprung oder die Vorsprünge etwa in einer Montagevorrichtung radial einzudrücken und dann das Bauteil überzuschieben. Um den Zusammenbau der Baugruppe zu erleichtern, wird jedoch fol- gendes vorgeschlagen: die dem freien Ende der Stange zugewandte Fläche des Vorsprunges bzw. der Vorsprünge und/oder die beim Aufschieben des Bauteils in dessen Bewegungsrichtung weisende Fläche werden so abgeschrägt, daß durch Auflaufen vorzugsweise einer Schrägfläche des Bauteils auf den bevorzugt abgeschrägten Vorsprung dieser radial eingedrückt wird (Anspruch 2) . Die beiden jeweils anderen, d. h. die vor dem Zusammenbau voneinander abgewandten Flächen von Bauteil und Vorsprung sollen dagegen so beschaffen sein, daß sie sich aufeinander abstützen können.In principle, it is possible to radially press in the projection or the projections, for example in an assembly device, and then slide the component over. In order to facilitate the assembly of the assembly, however, the following is proposed: the surface of the protrusion or the protrusions facing the free end of the rod and / or the surface pointing in the direction of movement when the component is pushed on are beveled in such a way that preferably by running up an inclined surface of the component is pressed radially onto the preferably beveled projection (claim 2). The other two, d. H. on the other hand, the surfaces of the component and the protrusion which face away from one another before the assembly should be such that they can be supported on one another.
Der Vorsprung kann etwa als Stift ausgebildet sein, der in der Stange nahe deren freiem Ende radial beweglich angeordnet ist, durch eine Feder auswärts gedrückt wird und radial so weit einwärts gedrückt werden kann, bis er voll in die Stange eingetreten ist.The projection can be designed approximately as a pin, which is arranged in the rod near its free end in a radially movable manner, is pressed outwards by a spring and can be pressed radially inwards until it has fully entered the rod.
Erfindungsgemäß ist es jedoch von Vorteil, in der Stange einen Längsschlitz auszubilden, der von deren freiem Ende ausgeht, achsparallel über einen kurzen Abschnitt dieser läuft und sich quer, bevorzugt diametral durch die Stange erstreckt (Anspruch 3) . Das Ende der Stange ist somit gegabelt, und das Material dieser Stange und die Abmessung des Schlitzes sind so ausgebildet, daß sie, von ihrer Ruhelage ausgehend, federnd zusammengedrückt werden können, aber nach der Frei- gäbe wieder in ihre Ruhelage zurückkehren.According to the invention, however, it is advantageous to form a longitudinal slot in the rod, starting from its free end, running axially parallel over a short section of this and extending transversely, preferably diametrically, through the rod (claim 3). The end of the rod is thus bifurcated, and the material of this rod and the dimension of the slot are designed such that they can be pressed together resiliently, starting from their rest position, but return to their rest position after the releases.
Auf der Außenseite mindestens eines dieser Gabelzinken sitzt der Vorsprung (Anspruch 4) . Dieser Vorsprung ist fest mit der Stange verbunden und etwa ein eingeschlage- ner Kerbstift. Stattdessen kann er auch einstückig mit der Stange ausgebildet sein. Diese letztgenannte Lösung hat den Vorteil gegenüber dem Stand der Technik, daß sich die Gesamtzahl der Bauteile verringert (der Sicherungsring oder Kerbstift entfällt) .The projection sits on the outside of at least one of these fork tines (claim 4). This protrusion is firmly connected to the rod and is a grooved pin, for example. Instead, it can also be formed in one piece with the rod. This latter solution has the advantage over the prior art that the total number of components is reduced (the locking ring or grooved pin is omitted).
Bevorzugt sind zwei einander gegenüberliegende Vorsprünge vorgesehen, die in Bezug auf den Längsschlitz symmetrisch angeordnet sind. Es kann auch nur ein solcher Vorsprung vorgesehen sein.Two mutually opposite projections are preferably provided, which are arranged symmetrically with respect to the longitudinal slot. Only such a projection can also be provided.
Wie schon eingangs vermerkt, ist die Stange bevorzugt als Feder-Zentrierstange ausgebildet, auf der die Schließfeder vorzugsweise einer Pistole sitzt. Diese Schließfeder stützt sich mit ihrem dem freien Ende der Feder- Führungsstange nahegelegenen Ende auf einer Ringsscheibe als Widerlager ab; dieses Ringscheibe bildet das Bauteil, das bei ausgebauter Baugruppe von dem oder den Vorsprung bzw. Vorsprüngen gegen die Kraft der Schließfeder gehalten wird (Anspruch 5) .As already noted at the beginning, the rod is preferably designed as a spring centering rod, on which the closing spring, preferably a pistol, sits. This closing spring is supported with its end near the free end of the spring guide rod on an annular disk as an abutment; this annular disc forms the component which is held by the projection or projections or projections against the force of the closing spring when the assembly is removed (claim 5).
Die Erfindung wird anhand eines Ausführungsbeispiels und der beigefügten Zeichnung noch näher erläutert; in dieser zeigt :The invention is explained in more detail using an exemplary embodiment and the accompanying drawing; in this shows:
Fig. 1 den vorderen Teil eines Längsschnitts durch eine Selbstladepistole, mit einer Schließfeder- Baugruppe aus dem Stand der Technik, Fig. 2 einen Längsschnitt wie in Fig. 1, jedoch mit einer erfindungsgemäßen Schließfeder-Baugruppe,1 shows the front part of a longitudinal section through a self-loading pistol, with a closing spring assembly from the prior art, 2 shows a longitudinal section as in FIG. 1, but with a closing spring assembly according to the invention,

Baugruppe der Fig. 3 und 4, im Schrägbild und ab- geschnitten.3 and 4, in the oblique image and cut off.
In Fig. 1 ist im Längsschnitt der vordere Teil einer verriegelten Selbstladepistole gezeigt, die in üblicher Weise einen Schlitten oder Verschluß 1, einen Lauf 3 und ein (nicht gezeigtes) Griffstück aufweist. Vorne an der Oberseite des Schlittens 1 ist eine Quernut 7 zur Aufnahme eines Kornes oder einer sonstigen Visiereinrichtung gezeigt .In Fig. 1, the front part of a locked self-loading pistol is shown in longitudinal section, which in the usual way has a slide or breech 1, a barrel 3 and a handle (not shown). A transverse groove 7 for receiving a grain or other sighting device is shown at the front on the upper side of the carriage 1.
Eine bekannte Feder-Zentrierstange 9 liegt unter dem Lauf 3 und ragt durch eine Bohrung in der vorderen Endfläche des Schlittens 1. Auf die Stange 9 ist eine wendeiförmige Schließfeder 11 aufgeschoben, die sich mit ihrem nicht gezeigten, hinteren Ende auf einem Element abstützt, das zumindest im gezeigten Zustand der Pistole (Verschluß 1 geschlossen und verriegelt) gegenüber dem Griffstück ortsfest ist. Das vordere Ende der Schließfeder 11 stützt sich über eine Ringscheibe 13, die mit ihrer Bohrung eng, aber verschieblich auf der Stange 9 aufsitzt, nach vorne hin am Verschluß 1 ab.A known spring centering rod 9 is located under the barrel 3 and protrudes through a bore in the front end face of the carriage 1. On the rod 9, a helical closing spring 11 is pushed, which is supported with its rear end, not shown, on an element that at least in the shown state of the gun (breech 1 closed and locked) with respect to the handle is stationary. The front end of the closing spring 11 is supported on the closure 1 towards the front by means of an annular disk 13 which, with its bore, sits tightly but displaceably on the rod 9.
Im vorderen Ende der Stange 9, an einer Stelle, die mit Spiel in der Bohrung in der vorderen Endfläche des Schlittens 1 sitzt, ist eine Ringnut (nicht gezeigt) aus- gebildet, in der eine Sicherungsscheibe 15 aus Federblech sitzt .In the front end of the rod 9, at a point that sits with play in the bore in the front end face of the slide 1, an annular groove (not shown) is formed formed, in which a locking washer 15 from spring plate sits.
Im gezeigten, eingebauten Zustand ist die Sicherungs- scheibe 15 scheinbar völlig unbelastet. Wird die Baugruppe aus Stange 9, Schließfeder 11, Ringscheibe 13 und Sicherungsscheibe 15 jedoch ausgebaut, dann kann die Schließfeder 11 sich ein wenig entspannen und stützt sich danach über die Ringscheibe 13 auf der Sicherungsscheibe 15 ab.In the installed state shown, the locking washer 15 appears to be completely unloaded. However, if the assembly of rod 9, closing spring 11, washer 13 and locking washer 15 is removed, the closing spring 11 can relax a little and is then supported on the locking washer 15 via the washer 13.
Wie schon oben vermerkt, kommt es bisweilen dazu, daß die Sicherungsscheibe zerspringt oder abspringt. Fehlt die Sicherungsscheibe 15, dann schiebt die Schließfeder 11 beim Ausbau die Ringscheibe 13 nach vorne von der Stange 9 herunter, so daß diese Ringscheibe 13 zu Boden fallen und verlorengehen kann.As noted above, it sometimes happens that the lock washer breaks or jumps off. If the locking washer 15 is missing, the closing spring 11 pushes the washer 13 downward from the rod 9 during removal, so that this washer 13 can fall to the ground and be lost.
Fig. 2 zeigt die erfindungsgemäße Baugruppe im eingebau- ten Zustand und Fig. 3 zeigt sie im ausgebauten Zustand. Die Fig. 4 bis 6 zeigen Einzelteile dieser Baugruppe. Die in der erfindungsgemäßen und in der bekannten Baugruppe identsichen Bauteile haben in allen Figuren die gleichen Bezugszeichen. Unterschiedlich sind lediglich die Feder- Zentrierstangen, welche in der bekannten Baugruppe das Bezugszeichen 9 hat, in der erfindunsgemäßenBaugruppe hingegen das Bezugszeichen 19. Außerdem weist die erfindungsgemäße Baugruppe keine Sicherungsscheibe 15 auf. Stattdessen ist das vordere Ende der Stange 19 mit einem Längsschlitz 21 versehen, der symmetrisch zur Längsachse der Stange 19 angeordnet ist. Die Länge des Schlitzes 21, der die Stange 19 auf ganzer Breite durchsetzt, beträgt etwa den 1,5-fachen Durchmesser der Stange 19. Die Höhe des Schlitzes 21 beträgt etwa ein Drittel des Durchmes- sers der Stange 19.FIG. 2 shows the assembly according to the invention in the installed state and FIG. 3 shows it in the removed state. 4 to 6 show individual parts of this assembly. The components which are identical in the assembly according to the invention and in the known assembly have the same reference symbols in all the figures. The only difference is the spring centering rods, which have the reference number 9 in the known assembly, but the reference number 19 in the assembly according to the invention. In addition, the assembly according to the invention has no locking washer 15. Instead, the front end of the rod 19 is provided with a longitudinal slot 21 which is arranged symmetrically to the longitudinal axis of the rod 19. The length of the slot 21, which passes through the rod 19 over its entire width, is approximately 1.5 times the diameter of the rod 19. The height of the slot 21 is approximately one third of the diameter of the rod 19.
Beiderseits des Schlitzes 21 und symmetrisch zu diesem ist jeweils ein Vorsprung 17 an der Außenseite der Stange 19 einstückig mit dieser ausgebildet. Jeder Vorsprung 17 ist auf der Seite, die dem nahen freien Ende der Stange 19 zugewandt ist, abgeschrägt. Auf der gegenüberliegenden Seite hingegen fällt er nicht nur steil bzw. rechtwinklig ab, sondern mündet am Grund auch noch in eine flache Ringnut in der Oberfläche der Stange 19 ein, um den üblichen, abgerundeten Übergang zwischen aneinandergrenzenden Flächen zu ermöglichen. Fig. 6 zeigt die Ausbildung der Stange 19 besonders deutlich.On both sides of the slot 21 and symmetrical to this, a projection 17 is formed on the outside of the rod 19 in one piece with this. Every projection 17 is bevelled on the side facing the near free end of the rod 19. On the opposite side, on the other hand, it not only falls steeply or at right angles, but also ends at the bottom in a flat annular groove in the surface of the rod 19 in order to enable the usual, rounded transition between adjoining surfaces. 6 shows the design of the rod 19 particularly clearly.
Die Fig. 3 und 4 zeigen das Ende der Stange 19 mit3 and 4 show the end of the rod 19 with
Ringscheibe 13 und Schließfeder 11 in ausgebautem Zustand, in welchem die Scheibe 13 von der Schließfeder 11 gegen die Vorsprünge 17 gedrückt wird und an diesen anliegt. - In Fig. 4 ist die Schließfeder 11 zur Verdeutli- chung der restlichen Bauteile weggelassen worden.Washer 13 and closing spring 11 in the disassembled state, in which the disk 13 is pressed by the closing spring 11 against the projections 17 and bears against them. 4, the closing spring 11 has been omitted to clarify the remaining components.
Fig. 5 zeigt die Ringscheibe 13 allein.Fig. 5 shows the washer 13 alone.
Wie ersichtlich, ist das über die Ringscheibe 13 überste- hende freie Ende der Stange 19 recht kurz, so daß es nicht ohne weiteres von einem Bastler in den Schraubstock gespannt und zusammengedrückt werden kann, um die Scheibe 13 zu entfernen. Ohne Scheibe 13 würde die Pistole wohl weniger störungsfrei funktionieren. Die Stange 19 wäre dann nämlich nicht geführt. Hierdurch auftretende Funktionsstörungen würden allerdings dem Hersteller angelastet nicht dem Bastler, der die Waffe. unvollständig zusammengesetzt hat. Dies ist nachteilig.As can be seen, the free end of the rod 19 protruding beyond the annular disk 13 is quite short, so that it cannot be easily clamped and compressed by a hobbyist in the vice to remove the disk 13. Without disk 13, the pistol would probably work less trouble-free. The rod 19 would then not be guided. Malfunctions that occur as a result, however, would be charged to the manufacturer, not to the hobbyist who uses the weapon. has composed incompletely. This is a disadvantage.
wie ein Vergleich der Fig. 1 und 2 zeigt, befindet sich im eingebauten Zustand der erfindungsgemäßen Baugruppe keines seiner Bauteile an derjenigen Stelle, an der die bekannte Sicherungsscheibe 15 angebracht war. Dort kann demnach auch nichts zu Bruch gehen. As a comparison of FIGS. 1 and 2 shows, none of its components is in the installed state of the assembly according to the invention at the point at which the known locking washer 15 was attached. Nothing can therefore break there.
