Description
Die vorliegende Erfindung bezieht sich auf ein handbetätigtes Austraggerät für Kartuschen mit einer auf eine Schubstange wirkenden Reibungsbremse gemäss Oberbegriff von Patentanspruch 1, sowie auf eine Bremsfeder zur Verwendung als Reibungsbremse in einem Austraggerät für Kartuschen.The present invention relates to a manual discharge device for cartridges with a a push rod acting friction brake according to the preamble of claim 1, as well as a brake spring for use as a friction brake in a discharge device for Cartridges.
Ein solches Austraggerät ist aus der US-A-4 826 053 des gleichen Anmelders bekannt. Die dort offenbarte Reibungsbremse besteht aus vielen Einzelteilen, die einen relativ grossen Platz beanspruchen und keine Ausrichtung bewirken.Such a discharge device is known from US-A-4 826 053 same applicant. The one revealed there Friction brake consists of many individual parts, one take up relatively large space and no alignment cause.
Aus der EP-A-791 404, ebenfalls vom gleichen Anmelder, ist eine vereinfachte Reibungsbremse offenbart, die nur aus einer Omegaförmigen Feder besteht. Es hat sich herausgestellt, dass eine solche Omegafeder schlecht auf die Toleranzen der Schubstange eingestellt werden kann und ausserdem die Schubstange nicht ausrichtet.From EP-A-791 404, also by the same applicant a simplified friction brake that only reveals an omega-shaped spring. It has pointed out that such an omega spring bad on the Tolerances of the push rod can be adjusted and also does not align the push rod.
Reibungsbremsen haben als primäre Aufgabe, nach Beendigung des Vorschubes den durch die Entlastung der flexiblen Kartuschen bedingten Entlastungsweg der Schubstange zu ermöglichen. Das heisst, die Schubstange möglichst wenig zu behindern, jedoch die während des Nachfasshubes durch das Vorschuborgan verursachte, auf die Schubstange wirkende Schleppkraft wirkungsvoll zu bremsen. Während beim Vorschub die Schubstange oder bei einer Zweikomponentenkartusche die Doppelschubstange infolge des Eingriffs des Vorschuborgans geführt ist, besteht beim Nachfasshub die Gefahr, dass die Schubstange leicht quergestellt wird und daher der saubere Eingriff mit den Zähnen des Vorschuborgans nicht mehr gewährleistet ist.Friction brakes are the primary job after finishing of the feed by relieving the flexible Cartridge-related relief path of the push rod too enable. That means closing the push rod as little as possible hinder, however, during the follow-up stroke by the Feed element caused acting on the push rod To effectively brake towing power. While feeding the push rod or in the case of a two-component cartridge Double push rod due to the engagement of the feed element there is a risk that the Push rod is easily crossed and therefore the clean one No more engagement with the teeth of the feed element is guaranteed.
Es ist von diesem Stand der Technik ausgehend Aufgabe der vorliegenden Erfindung, ein handbetätigtes Austraggerät mit Reibungsbremse anzugeben, das die oben geschilderten Nachteile nicht aufweist und eine kostengünstig herstellbare Reibungsbremse enthält, die sowohl die Schubstange beim Nachfasshub wirkungsvoll bremst als auch die Schubstange oder bei Zweikomponentenkartuschen die Doppelschubstange derart ausrichtet, dass beim Nachfassen die Verzahnung des Vorschuborgans einwandfrei in die Verzahnung der Schubstange eingreifen kann.Starting from this prior art, it is the task of present invention, a hand-operated discharge device with Specify friction brake that the above Does not have disadvantages and an inexpensive to produce Contains friction brake, which both the push rod when Follow-up stroke effectively brakes as well as the push rod or in the case of two-component cartridges, the double push rod aligns in such a way that the teeth of the Feed organ perfectly in the toothing of the push rod can intervene.

In der vorliegenden Anmeldung sind nur die für das Verständnis und für die Wirkungsweise der erfindungsgemässen Reibungsbremse notwendigen Teile des Austraggeräts beschrieben. Für die übrigen Teile und die Wirkungsweise des Austraggeräts wird auf die vorgenannte EP-A-791 404 Bezug genommen, die Ausführungsbeispiele offenbart.In the present application, only those for Understanding and for the mode of operation of the inventive Friction brake necessary parts of the discharge device described.

In den Figuren 1 und 2 ist ein Teil des Gehäuses 1
dargestellt, das im wesentlichen aus dem Gehäusekörper 2 und
dem Deckel 3 besteht. Man erkennt ferner die Doppel-Schubstange
4, im nachfolgenden nur noch Schubstange
benannt, da es nicht erfindungswesentlich ist, ob es sich um
eine einfache oder um eine Doppel-Schubstange handelt, mit
den beiden Stösselplatten 5 und 6, die entweder den gleichen
Querschnitt aufweisen können oder einen unterschiedlichen
Querschnitt für Kartuschen mit unterschiedlichen Volumina
bzw. Querschnittsflächen. Ausserdem wird in der vorliegenden
Beschreibung mit "vorne" das stösselplattenseitige Ende und
dementsprechend mit "hinten" das andere Ende gemeint.In FIGS. 1 and 2, part of the housing 1
shown, which consists essentially of the
Die hier eingezeichnete Schubstange 4 besitzt am hinteren
Ende eine Lasche 7, um sie daran für das Auswechseln der
Kartusche zurückziehen zu können. Die Schubstange 4 besitzt
ferner eine Verzahnung 8, siehe auch Figur 6, in die die mit
einer Verzahnung 9 versehene Klinke 10 eines Vorschuborgans
11 greift. In Figur 6 erkennt man ferner den Drehpunkt 12
des Vorschuborgans sowie den Hebel 13, um das Vorschuborgan
zu schwenken und die Zähne ausser Eingriff zu bringen und
somit den Rückzug der Schubstange zu ermöglichen.The
Wichtig für das einwandfreie Funktionieren des Vorschubs
sowie des Entlastungsweges und das Nachfassen ist eine
genaue Führung der Schubstangen sowie ein exaktes Eingreifen
der Zähne des Vorschuborgans in die Verzahnung der
Schubstangen. In erster Näherung wird die Führung dadurch
gewährleistet, dass die Schubstangen Stege 14 und 15
aufweisen, die sich längs der Schubstange erstrecken und
senkrecht zur Ebene 8E stehen, auf der die Verzahnung 8
angeordnet ist und dass diese Stege in entsprechend
geformten Führungen im Gehäuse geführt sind, wobei
entsprechende hintere Führungen 16 und 17 sowie vordere
Führungen 18 und 19 in Figur 1 gezeigt werden, während in
Figur 2 die vorderen Führungen 18 und 19 dargestellt sind.
Wie aus der nachfolgenden Beschreibung und Wirkungsweise der
Reibungsbremse hervorgehen wird, ist es vor allem wichtig,
dass mindestens eine Schubstange mindestens einen Steg nach
oben, d.h. zum Deckel des Gehäuses hin gerichtet, aufweist.Important for the proper functioning of the feed
as well as the relief route and follow-up is one
precise guidance of the push rods as well as exact intervention
of the teeth of the feed element in the toothing of the
Pushrods. In the first approximation, the leadership
ensures that the connecting
Wollte man mit diesen Massnahmen allein eine genaue Führung bewirken, müssten sowohl die Führungsnuten als auch die Stege an den Schubstangen sehr genau und mit sehr geringen Toleranzen gearbeitet sein. Solch enge Toleranzen sind jedoch bei der Massenherstellung dieser Produkte nicht möglich. Es wurde nun erkannt, dass es möglich ist, mit einer entsprechend gestalteten Bremsfeder nicht nur die Forderungen zu erfüllen, die an eine wirksame Reibungsbremse gestellt werden, sondern auch eine exakte Führung der Schubstange, sei es eine einzelne Schubstange oder eine Doppelschubstange, zu bewirken. If these measures alone were to be used for precise guidance effect, both the guide grooves and the Bridges on the push rods very precisely and with very little Tolerances worked. Such tight tolerances are but not in the mass production of these products possible. It has now been recognized that it is possible to use a correspondingly designed brake spring not only that To meet requirements for an effective friction brake be put, but also an exact management of the Push rod, be it a single push rod or one Double push rod.
In den Figuren 1 bis 5B ist eine als Bremsfeder 20
ausgebildete Reibungsbremse dargestellt, die nicht nur die
Aufgaben einer Reibungsbremse erfüllt, sondern auch die
Schubstange dann exakt führt, wenn die Zähne des
Vorschuborgans wieder eingreifen sollen. Gemäss Figur 3
besteht die Feder 20 im wesentlichen aus einem Schlaufenteil
21, der einen Radius R aufweist, sowie einem daran
anschliessenden Klemm- und Ausrichtteil, der aus den beiden
Schenkeln 22 und 23 besteht. Wie am besten aus den Figuren 1
und 5 hervorgeht, ist der eine Schenkel 22 geradlinig,
während der andere Schenkel 23 gebogen oder abgewinkelt ist,
so dass die Feder insgesamt bezüglich ihrer Längsachse
asymmetrisch ausgebildet ist. Der geradlinige Schenkel 22
weist ferner ein Langloch 24 zur Sicherung und Wegbegrenzung
auf.1 to 5B is a
Durch diese spezielle Federform wird einmal bewirkt, dass
die Schubstange, bzw. deren Steg, im Beispiel gemäss Figur 1
Steg 15, stets geradlinig ausgerichtet und gegen die beiden
Aussenkanten 25 und 26 der hinteren Führung 17 und der
vorderen Führung 19 gedrückt wird. Ausserdem erlaubt die
Form des Schlaufenteils die Federkraft, abgesehen vom
Einfluss der Wandstärke und des Materials, durch die Grösse
von Radius R präzise abzustimmen.This special shape of the spring causes that
the push rod, or its web, in the example according to FIG. 1
Die ausgerichtete Stellung gemäss Figur 1 entspricht der
Schubstangenstellung von Figur 5A, in welcher skizziert ist,
dass der Steg 15 der Schubstange gegen die beiden Kanten 25
und 26 der Führungen 17 und 19 anliegt.The aligned position according to Figure 1 corresponds to
Push rod position of Figure 5A, in which is sketched,
that the
In vorliegendem Ausführungsbeispiel ist die Feder am Deckel
des Gehäuses angebracht, wobei sie an der Innenseite der
Aussenwand 27 des Deckels anliegt und zwischen der
Innenseite der Aussenwand und einem zu dieser mit Abstand
angeordneten Führungssteg 28 eingeklemmt ist. Der
Führungssteg dient der genauen Ausrichtung des geraden
Schenkels 22 der Bremsfeder, wobei die beiden Führungskanten
25 und 26 sowie die der Aussenwand zugewandte Anschlagfläche
29 des Führungsstegs in einer Ebene liegen. Die Höhe des
Führungsstegs entspricht etwa der Höhe des Absatzes 30 an
der Bremsfeder, siehe Figur 3, so dass der Steg 15 unter dem
Führungssteg durchgleitet. Es ist selbstverständlich, dass
der Führungssteg 28 eine etwas kleinere Dicke aufweist als
der Steg 15, um diesen wirksam einzuklemmen.In the present exemplary embodiment, the spring is on the cover
of the housing attached, being on the inside of the
In der Innenseite der Aussenwand 27 befinden sich zwei
Anschläge für die Bremsfeder, der vordere Anschlag 31 und
der hintere Anschlag 32. Der Weg, den die Bremsfeder
zurückweicht, der als freier Entlastungsweg definiert ist,
ist in Figur 1 mit B bezeichnet. Zur Sicherung der
Bremsfeder und auch zur Begrenzung des freien
Entlastungsweges ist ein Stift durch die Aussenwand und
durch das Langloch 24 vorgesehen, so dass die Bremsfeder
zwar gesichert, aber in Längsrichtung um einen bestimmten
Weg verschiebbar ist.There are two in the inside of the
Im folgenden wird die Wirkungsweise der erfindungsgemässen Reibungsbremse beschrieben.The mode of operation of the invention is described below Friction brake described.
Unter Last, d. h. beim Austrag, bleibt die Schubstange zum Gehäuse ausgerichtet, auch wenn verschiedene Kräfte auf die Schubstange ausgeübt werden können, wie dies insbesondere bei einer Doppel-Schubstange der Fall ist und wenn das Verhältnis der Volumina der Kartuschen bzw. das Verhältnis der Querschnitte, vom Verhältnis 1 : 1 abweicht und beispielsweise 1 : 4 oder 1 : 10 beträgt, weil der sägezahnartige Zahneingriff des Schuborgans die Schubstange nach der spielarm eingebauten Klinke des Schuborgans ausrichtet. Beim Entlastungsweg und dem Nachfasshub durch die Klinke hingegen fällt diese Ausrichtung weg, weil unterschiedliche Kräfte oder unterschiedliche Reibungssituationen eine seitliche Verschiebung oder eine Schrägstellung der Schubstange bewirken können, wie dies in Figur 5B dargestellt ist.Under load, i.e. H. when discharging, the push rod remains to Housing aligned, even when different forces on the Push rod can be exercised, like this in particular is the case with a double push rod and if that Ratio of the volumes of the cartridges or the ratio the cross sections, deviates from the ratio 1: 1 and for example 1: 4 or 1:10 because of the sawtooth-like meshing of the thrust member the push rod after the ratchet of the thrust member installed with little play aligns. With the relief path and the follow-up stroke the jack, however, does not have this orientation because different powers or different Frictional situations a lateral shift or a Inclination of the push rod can cause such as in Figure 5B is shown.
Nach Beendigung des Nachfasshubes richtet die leicht
verspannte Bremsfeder die Schubstange wieder nach der
hinteren und vorderen Kante 25 und 26 der Führungen aus,
während der gerade Schenkel 22 der Feder an der
Anschlagfläche 29 des Führungsstegs ausgerichtet wird und
abstützt. Dadurch wird erreicht, dass beim Nachfassen und
beim Beginn des Austraghubes die Verzahnung der Schubstange
und die Klinkenzähne genau ausgerichtet sind und die Klinke
nicht durch unsauberen Zahneingriff beim Einrastvorgang
hängen bleibt, was zu Beschädigungen der Verzahnung an der
Schubstange und der Klinke sowie zu Knackgeräuschen führen
kann.After completing the follow-up stroke, it straightens easily
tensioned brake spring the push rod again after the
rear and
Aus obiger Beschreibung geht hervor, dass die Ausrichtung der Schubstange durch die erfindungsgemässe Bremsfeder alleine einwandfrei bewirkt werden kann, wodurch die Einzelteil- sowie die Montagekosten stark reduziert werden, was gerade für grosse Stückzahlen wesentlich ist, und ausserdem, dass die Schubstange gegenüber dem Gehäuse nur eine sehr kleine Reibung aufweist, was sich günstig auf die Entlastung der Kartusche auswirkt.From the above description it is clear that the alignment the push rod by the brake spring according to the invention alone can be effected flawlessly, whereby the Component and assembly costs are greatly reduced, which is essential for large quantities, and also that the push rod is only opposite the housing has a very low friction, which is beneficial to the Relief of the cartridge affects.
Die erfindungsgemässe Bremsfeder wurde anhand eines Beispiels einer Doppelkartusche beschrieben, da sie gerade dort von besonderem Vorteil ist, denn die Bremsfeder braucht nur auf einen Steg einer Schubstange zu wirken, um die ganze Schubstange, d. h. die Doppel-Schubstange, auszurichten, wobei es unerheblich ist, ob die Stösselplatten der Schubstange Kartuschen mit einem Verhältnis von 1 : 1 oder ein unterschiedliches Verhältnis bis zu einem Verhältnis von 1 : 10 auspressen. Die erfindungsgemässe Bremsfeder kann jedoch auch für Austraggeräte mit nur einer Schubstange eingesetzt werden.The brake spring according to the invention was based on a Example of a double cartridge described because it is straight there is a particular advantage because the brake spring needs to act only on a web of a push rod to the whole Push rod, d. H. to align the double push rod, it is irrelevant whether the pusher plates of the Push rod cartridges with a ratio of 1: 1 or a different ratio up to a ratio of Squeeze 1:10. The brake spring according to the invention can however also for discharge devices with only one push rod be used.
