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

Die Erfindung betrifft eine Baugruppe für Handfeuerwaffen, nach dem 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, according to the preamble of claim 1. It is in in this connection referred 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. Üblicherweise 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 disassemble the handgun to be expanded, but should not in turn or for the time being cannot be further dismantled; about because then the Reinstalling the assembly is too difficult. Usually is such an assembly by a lock washer held together indivisibly, into one Ring groove is pressed near the free end of the rod and is stuck there springy. Such lock 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. These lock washers are used only for cohesion the removed assembly; with built-in These lock washers remain inoperative and don't take on any powers.

Ein besonders typisches Beispiel für eine derartige Baugruppe ist die Schließfedereinrichtung von Selbstladepistolen mit Colt-Browning-Verriegelung: Am hinteren Ende einer Feder-Zentrierstange ist ein Raststück fest angebracht. Auf die Stange selbst ist eine wendelförmige 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.A particularly typical example of such an assembly is the closing spring device of self-loading pistols with Colt-Browning lock: at the rear end a spring centering rod has a locking piece. On the pole itself is a helical one Closing spring pushed on. This is followed by an annular one Spring support plate, commonly referred to here as a component is. The spring is in a relieved state longer than the spring centering rod, so that the assembly is quite tricky. To make this assembly easier, is in the front end of the spring centering rod-one Ring groove formed in which a locking washer sits. When the closing spring device is removed, it presses slightly compressed spring the spring support plate against the lock washer, but can not from the Push down the spring centering rod. When assembling the closing spring device from below into the Carriage of the pistol inserted, in which the Barrel, pushed slightly forward and into the locking body engaged at the end of the barrel. In this When installed, the closing spring is a little further compressed than before, so that the lock 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 bounce when using the weapon. Obviously they don't survive vibrations that are on the spring centering rod was applied during the shot. The function of the weapon is usually not impaired, but after the next disassembly is the reassembly considerably more difficult.

Natürlich wurden die zu Bruch gegangenen oder abgesprungenen 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 aufgesetzt hatte. Befragungen der Kunden konnten diese Annahme jedoch nicht bestätigen.Of course, those that broke or jumped off Lock washers and the associated ring groove in detail examined and measured, but without irregularities to discover. It was therefore considered that the customer improperly locks the lock washer on the weapon removed, damaged and then replaced would have. Customer surveys made this assumption but do not confirm.

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 without but a reasonable generalization has been possible would be to track down the cause of the damage come.

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 have a bag with lock washers (a penny item) each delivered Grab your gun. In a way, this would be an admission mean a defective or at least not yet fully designed, but in any case not fully reliable weapon is shipped. Since the But customers demand the highest level of reliability Approach has been discarded.

Aufgabe der Erfindung ist es, die eingangs genannte Baugruppe dahingehend weiterzubilden, daß sie beim Ausbau sicherer zusammenhält.The object of the invention is the assembly mentioned above to further educate them in the process of expansion holds together more securely.

Diese Aufgabe wird erfindungsgemäß durch den Gegenstand des Anspruchs 1 gelöst, also dadurch, daß in der gattungsgemäßen Baugruppe an der Stange mindestens ein abgefederter Vorsprung angeordnet oder ausgebildet ist, der beim Aufschieben des Bauteils auf die Stange ausweicht, danach wieder in seine Ruhelage zurückkehrt und in dieser bei ausgebauter Baugruppe mit dem Bauteil in rückhaltenden Eingriff tritt. Eine solche Halteanordnung ist aus der US 5 127 310 bekannt, aber in anderem Zusammenhang.This object is achieved by the subject of claim 1 solved, that is in that in the generic Assembly on the rod at least one sprung Projection is arranged or formed, the dodges when pushing the component onto the rod, then returns to its rest position and in this position when the assembly is removed with the component in restrained Intervention occurs. Such a holding arrangement is out known from US 5,127,310, but in a different context.

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 omitted and at their Place a protrusion arranged radially outward is spring-loaded. In its rest position (the most radially external position) occurs the appropriately dimensioned and trained projection may be engaged with the component to prevent this from the rod slips. The cushioning of the projection leaves but to the fact that it is lowered radially so far inwards can be that the component over the projection on or off the bar can.

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 the durability of the assembly according to the invention result, although it was ultimately not known exactly why the earlier lock washers burst and now the lead 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 folgendes 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.It is basically possible to have the protrusion or the protrusions about to press radially in a mounting device and then slide the component over. To assemble to facilitate the assembly, however, will be the following suggested: the one facing the free end of the rod Area of the protrusion or protrusions and / or when the component is pushed on in its direction of movement facing surfaces are bevelled so that preferably by running up an inclined surface of the Component on the preferably bevelled projection of this is pressed radially (claim 2). The two of them other, d. H. those facing away from each other before assembly In contrast, surfaces of component and protrusion should be designed to support each other can.

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 as a pin, for example arranged radially movable in the rod near its free end is pressed outwards by a spring and can be pushed radially inwards until it is full got into the bar.

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). According to the invention, however, it is advantageous in the bar to form a longitudinal slot from its free end goes out, axially parallel over a short section of this runs and runs across, preferably diametrically through the bar extends (claim 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 Freigabe wieder in ihre Ruhelage zurückkehren.The end of the bar is forked, and the material this rod and the dimension of the slot are so trained that they, starting from their rest position, resilient can be squeezed but after the release return to their rest position.

Auf der Außenseite mindestens eines dieser Gabelzinken sitzt der Vorsprung (Anspruch 4). Dieser Vorsprung ist fest mit der Stange verbunden und etwa ein eingeschlagener 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).At least one of these forks on the outside the projection sits (claim 4). That lead is firmly connected to the rod and about a hammered one Cotter pin. Instead, it can also be made in one piece the rod be formed. This latter solution has the advantage over the prior art that the total number of components is reduced (the circlip 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 preferred provided that symmetrical with respect to the longitudinal slot are arranged. It can only be such a head start 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 noted at the beginning, the rod is preferred as Spring centering rod formed on which the closing spring preferably a pistol sits. This closing spring is supported with the free end of the spring guide rod nearby end on an washer as abutment; this ring disk forms the component, that with the assembly removed from the or the projection or projections held against the force of the closing spring will (claim 5).

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 is in longitudinal section Self loading pistol shown in the usual way a carriage or breech 1, a barrel 3 and a Has grip (not shown). In the front at the top the carriage 1 is a transverse groove 7 for receiving a grain or some other sighting device.

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 wendelförmige 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 under the barrel 3 and protrudes through a hole in the front end surface of the carriage 1. On the rod 9 is a helical Closing spring 11 pushed on, which is not with her shown, the rear end is supported on an element that at least when the pistol is shown (breech 1 closed and locked) opposite the handle is stationary. The front end of the closing spring 11 supports over an annular disc 13 which is narrow with its bore, but slidably on the rod 9, forward towards the closure 1.

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) ausgebildet, in der eine Sicherungsscheibe 15 aus Federblech sitzt.In the front end of the rod 9, at a point that with Play in the hole in the front end face of the Seated slide 1, an annular groove (not shown) is formed, in the one lock washer 15 made of spring plate sitting.

Im gezeigten, eingebauten Zustand ist die Sicherungsscheibe 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.The locking washer is in the installed state shown 15 apparently completely unencumbered. Will the assembly from rod 9, closing spring 11, washer 13 and locking washer 15 expanded, however, then the Closing spring 11 relax a little and is supported then over the washer 13 on the locking washer 15 from.

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. Missing that Lock washer 15, then pushes the closing spring 11 when removing the washer 13 to the front of the rod 9 down so that this washer 13 fall to the ground and can get lost.

Fig. 2 zeigt die erfindungsgemäße Baugruppe im eingebauten 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 Durchmessers der Stange 19.Fig. 2 shows the assembly according to the invention in the built-in Condition and Fig. 3 shows it in the removed state. 4 to 6 show individual parts of this assembly. The in the assembly according to the invention and in the known assembly Identical components have the same in all figures Reference numerals. The only difference is the spring centering rods, which in the known assembly Has reference numeral 9 in the assembly according to the invention however, the reference number 19. In addition, the invention Assembly no lock washer 15. Instead, the front end of the rod 19 is one Provided longitudinal slot 21, which is symmetrical to the longitudinal axis the rod 19 is arranged. The length of the slot 21, which passes through the rod 19 over its entire width is about 1.5 times the diameter of the rod 19. The height the slot 21 is about a third of the diameter 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 is a projection 17 on the outside of the rod 19 integrally formed with this. Every projection 17 is on the side that is near the free end of the rod 19 facing, beveled. On the opposite On the other hand, it not only falls steeply or at right angles but also flows into a flat one at the bottom Ring groove in the surface of the rod 19 a to the usual, rounded transition between adjacent To enable surfaces. Fig. 6 shows the formation of the Rod 19 particularly clearly.

Die Fig. 3 und 4 zeigen das Ende der Stange 19 mit 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 Verdeutlichung der restlichen Bauteile weggelassen worden.3 and 4 show the end of the rod 19 with Washer 13 and closing spring 11 in the disassembled state, in which the disc 13 from the closing spring 11th is pressed against the projections 17 and abuts them. - In Fig. 4, the closing spring 11 is for clarification the remaining components have been omitted.

Fig. 5 zeigt die Ringscheibe 13 allein.Fig. 5 shows the washer 13 alone.

Wie ersichtlich, ist das über die Ringscheibe 13 überstehende 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, this protrudes beyond the washer 13 free end of the rod 19 quite short, so that it not easily by a hobbyist in the vice can be tensioned and compressed to the disc 13 to remove. Without target 13 the pistol would be fine work less trouble-free. The rod 19 would be then not led. Malfunctions that occur as a result would however be blamed on the manufacturer not the hobbyist who assembled the weapon incompletely Has. 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, there is in the installed state of the assembly according to the invention none of its components at the point where the known lock washer 15 was attached. There can therefore nothing will break.
