Description

Die Erfindung betrifft einen Keg-Zapfer zum Ausschenken einer Flüssigkeit, insbesondere eines unter Druck stehenden Getränkes, aus einem mit einem Keg-Verschluß versehenen Behälter, bestehend aus einem mit einem Druckerzeugungselement in Verbindung stehenen und einem Druckraum umschließenden Gehäuse, durch das eine mit einem Keg-Verschluß zusammenwirkende, axial bewegbare Ventilöffnungsstange gesteckt ist, die an einem über die Gehäusewand vorstehenden Ende als Ventilöffnungselement gestaltet und an ihrem gegenüberliegenden Ende mit einem Betätigungsteil verbunden ist.The invention relates to a keg dispenser for pouring out a liquid, in particular a pressurized beverage, from a container provided with a keg closure, consisting of a housing which is connected to a pressure generating element and encloses a pressure chamber, through which a housing with a keg Closure cooperating, axially movable valve opening rod is inserted, which is designed as a valve opening element at one end projecting beyond the housing wall and is connected at its opposite end to an actuating part.

Keg-Zapfer werden in der Gastronomie zum Zapfen von Bier aus Fässern verwendet, wobei Zapfköpfe für den Korbfitting und solche für den Flachfitting bekannt sind. Beide Ausführungen bestehen aus einem eine Druckkammer umschließenden Gehäuse, durch das eine hebelbetätigte Ventilöffnungsstange zum Öffnen des Ventils des Keg-Verschlusses gesteckt ist. Der Zapfkopf weist einen Druckgasanschluß und einen Anschluß für einen zum Zapfhahn führenden Schlauch auf. Keg-Zapfer dieser Art sind für den Hausgebrauch nicht geeignet.Keg taps are used in the catering industry for tapping beer from barrels, with tapping heads for basket fitting and those for flat fitting being known. Both versions consist of a housing enclosing a pressure chamber, through which a lever-operated valve opening rod is inserted to open the valve of the keg lock. The tap head has a compressed gas connection and a connection for a hose leading to the tap. Keg dispensers of this type are not suitable for domestic use.

Aus der US-A 4 516 698 ist weiterhin ein Keg-Zapfer zum Ausschenken eines unter Druck stehenden Getränkes aus einem mit einem Keg-Verschluß versehenen Behälter bekannt, der ein mit einem Druckerzeugungselement in Verbindung stehendes und einen Druckraum umschließendes Gehäuse und eine mit einem Keg-Verschluß zusammenwirkende, axial bewegbare Ventilöffnungsstange aufweist, die an einem Ende als Ventilöffnungselement gestaltet und an ihrem gegenüberliegenden Ende mit einem Betätigungsteil verbunden ist.From US-A 4 516 698 a keg dispenser for serving a pressurized beverage from a container provided with a keg closure is also known, which has a housing connected to a pressure generating element and enclosing a pressure chamber and one with a keg -Closure cooperating, axially movable valve opening rod, which at one end as a valve opening element designed and connected at its opposite end to an actuating part.

Nachteilig bei diesem Stand der Technik ist jedoch, daß zunächst vor Anbringen des Zapfers von Hand der Keg-Verschluß des Behälters geöffnet werden muß.A disadvantage of this prior art, however, is that the keg closure of the container must first be opened by hand before the tap is attached.

Daher schlägt das EP 0 283 797 vor, das Anstechen mit Hilfe eines Absenkens der Ventilöffnungsstange durch einen Gewindering vorzunehmen, wobei die Drehbewegung des Gewinderinges sowohl den Bügel mit dem in diesem angeordneten Flüssigkeitskanal als auch die mit diesem verbundene Ventilöffnungsstange absenkt.EP 0 283 797 therefore proposes that the piercing be carried out by lowering the valve opening rod by means of a threaded ring, the rotational movement of the threaded ring lowering both the bracket with the liquid channel arranged therein and the valve opening rod connected to it.

Diese Drehbewegung des Gewinderinges hat sich als verbesserungsbedürftig erwiesen, da die Schraubbewegung mehrere Handgriffe erfordert, was z.B. bei schnellen Faßwechseln hinderlich ist und zum anderen eine Kontrolle des vollständigen Anstechens des Kegs nur schwer möglich ist und ein Drehen des Schraubringes bis zum Anschlag die Gewinde der aus Kunststoff gefertigten Teile überbeansprucht. Gleichzeitig soll aber auch die Einstückigkeit des Gehäuses beibehalten werden.This rotary movement of the threaded ring has proven to be in need of improvement, since the screwing movement requires several handles, which e.g. is a hindrance for quick barrel changes and on the other hand it is difficult to check that the keg has been fully pierced and turning the screw ring as far as it will go would overstress the threads of the plastic parts. At the same time, however, the one-piece construction of the housing should also be maintained.

Die vorliegende Neuerung hat sich daher die Aufgabe gestellt, einen derartigen Keg-Zapfer dahingehend zu verbessern, daß unter Beibehalt der Einstückigkeit des Gehäuses die Auf- und Abwärtsbewegung der Ventilöffnungsstange mit Hilfe eines Hebelmechanismus möglich wird.The present innovation has therefore set itself the task of improving such a keg tap to the extent that the upward and downward movement of the valve opening rod is possible with the help of a lever mechanism while maintaining the one-piece construction of the housing.

Die vorliegende Neuerung besteht zur Lösung dieser Aufgabe aus einem Keg-Zapfer zum Ausschenken einer unter Druck stehenden Flüssigkeit aus einem mit einem Keg-Verschluß versehenen Behälter, mit einem einen Druckraum umschließenden Gehäuse, durch das eine mit Keg-Verschluß zusammenwirkende, axial bewegbare Ventilöffnungsstange gesteckt ist, die an einem über eine Gehäusewand vorstehenden Ende als Ventilöffnungselement gestaltet und mit einem Betätigungsteil verbunden ist, wobei das Gehäuse im wesentlichen zylindrisch ist, und die das Gehäuse durchquerende Ventilöffnungsstange einen durchgehenden, im Ventilöffnungselement nach außen mündenden Flüssigkeitsdurchlauf aufweist, der an seinem gegenüberliegenden Ende in einer hier im wesentlichen im rechten Winkel zum Flüssig-keitsdurchlauf angeordneten Flüssigkeitskanal übergeht, der in einem durch eine Ausnehmung in der Wand des Gehäuses gesteckten Bügel ausgespart ist, und einen mit einem Absperrventil verschließbaren Auslauf für die Flüssigkeit aufweist, und wobei der Bügel und die Ventilöffnungsstange gemeinsam angehoben und gesenkt werden, bei welchem erfindungsgemäß im unteren Ende des Gehäuses ein Einsatz angeordnet ist, der von der Ventilöffnungsstange durchgriffen wird und in dem Bohrungen an Halteelementen angeordnet sind, in die Zapfen eines mit einer Gabel versehenen, festlegbaren Hebels hineinragen, wobei nahe der Bohrungen des Einsatzes an der Ventilöffnungsstange ein oberer und ein unterer Flansch angeformt sind, zwischen die ebenfalls gegenüberliegende Zapfen der Gabel greifen, und wobei die Ventilöffnungsstange mit Hilfe des Hebels auf- und abbewegbar ist und auf das untere Ende des Gehäuses eine dieses teilweise umgreifende Muffe aufgeschoben und fixiert ist, wobei Gehäuse, Einsatz und Muffe seitlich neben der Ventilöffnungsstange liegende Schlitze aufweisen, in denen die Gabel des Hebels geführt ist, und wobei an die Muffe Halteelemente zur Befestigung des Zapfers auf dem Keg angeformt sind.To solve this problem, the present innovation consists of a keg tapper for pouring out a pressurized liquid from a container provided with a keg closure, with a container enclosing a pressure chamber Housing, through which an axially movable valve opening rod cooperating with a keg plug is inserted, which is designed as a valve opening element at one end projecting from a housing wall and is connected to an actuating part, the housing being essentially cylindrical, and the valve opening rod passing through the housing is one has continuous, in the valve opening element outwardly flowing liquid passage, which at its opposite end merges into a liquid channel arranged here essentially at right angles to the liquid passage, which is recessed in a bracket inserted through a recess in the wall of the housing, and one with has a shut-off valve closable outlet for the liquid, and wherein the bracket and the valve opening rod are raised and lowered together, in which, according to the invention, an insert is arranged in the lower end of the housing, which is from the V Passed through the valve opening rod and in which holes on the holding elements are arranged, protrude into the pins of a lever which is provided with a fork and can be fixed, with an upper and a lower flange being formed near the holes of the insert on the valve opening rod, between the likewise opposite pins of the fork grip, and wherein the valve opening rod can be moved up and down by means of the lever and a partially encompassing sleeve is pushed and fixed onto the lower end of the housing, the housing, insert and sleeve having slots on the side next to the valve opening rod, in which the fork of the lever is guided, and wherein on the sleeve holding elements are formed for fastening the tap on the keg.

Dabei ist die Ventilöffnungsstange nunmehr durch einen im Gehäuse unten ortsfest angebrachten Einsatz geführt, das ein Lager für die Enden eines in eine Gabel auslaufenden Hebels bildet. Das Gehäuse besitzt dabei Schlitze, durch die die Gabel von außen in dieses und die Schlitze des dahinterliegenden Einsatzes einführbar ist, und bei welcher die Zapfen an den Gabelenden zur Montage in die Bohrungen an dafür vorgesehenen Stegen des Einsatzes durch die Federwirkung der aus Kunststoff gefertigten Gabel einschnappen. Gleichzeitig weist die Ventilöffnungsstange etwa in Höhe der Lagerbohrungen des Einsatzes einen oberen und unteren Flansch auf, zwischen die beidseitig ebenfalls an der Innenseite der Gabel angeordnete Zapfen eingreifen, über die die Ventilöffnungsstange entsprechend der Hebelbewegung gehoben und gesenkt wird. Derart wird der Hebel gleichzeitig gegen Herausziehen gesichert.The valve opening rod is now guided through an insert which is fixed in the lower part of the housing and forms a bearing for the ends of a lever running out into a fork. The housing has slots through which the fork can be inserted from the outside into this and the slots of the insert behind it, and in which the pins on the fork ends for mounting in the bores on the ridges provided for this purpose by the spring action of the fork made of plastic snap in. At the same time, the valve opening rod has an upper and lower flange approximately at the level of the bearing bores of the insert, between which engage pins arranged on both sides on the inside of the fork, via which the valve opening rod is raised and lowered in accordance with the lever movement. In this way, the lever is secured against being pulled out at the same time.

Auf das Gehäuse ist dabei eine Muffe von unten aufgeschoben und mit diesem verbunden, wobei dieses ebenfalls Schlitze trägt und die notwendigen Befestigungsmittel für die Verbindung mit dem Keg, z.B. in Form einen Gewindes, aufweist.A sleeve is slid onto the housing from below and connected to it, which also has slots and the necessary fastening means for the connection to the keg, e.g. in the form of a thread.

Der Einsatz trägt dabei vorteilhaft ein Rückschlagventil zwischen den Schlitzen, so daß die Gabel sowohl die Ventilöffnungsstange als auch den Sitz des Rückschlagventils zwischen sich aufnimmt, und der Mantel des darüberliegenden Teils des Gehäuses dient in an sich bekannter Weise als Zylinder eines Luftpumpe, die Muffe ist dazu mit einem Anschluß für Druckluftzuführung über das Rückschlagventil in das Keg versehen.The insert advantageously carries a check valve between the slots, so that the fork receives both the valve opening rod and the seat of the check valve between them, and the jacket of the overlying part of the housing serves in a manner known per se as a cylinder of an air pump, which is a sleeve To do this, provide a connection for compressed air supply via the check valve in the keg.

Der Hebel muß in seiner unteren Lage gesichert werden. Dazu wird vorgeschlagen, über das untere Ende der Muffe einen Ring aus Kunststoff zu schieben, der einen Riegel trägt und mit dem Hebel verhakt werden kann. Der Hebel besitzt dazu eine an diesen angeformte Kante. Insbesondere kann dabei die Federwirkung des Riegels dazu genutzt werden, daß er beim Hinunterdrücken des Hebels selbsttätig über die Kante des Hebels schnappt. Zum Öffnen braucht der Riegel gegen seine Federwirkung lediglich geringfügig zurückgeschoben werden, um den Hebel freizugeben.The lever must be secured in its lower position. For this purpose, it is proposed to slide a plastic ring over the lower end of the sleeve, which carries a bolt and can be hooked with the lever. For this purpose, the lever has an edge molded onto it. In particular, the spring action of the bolt can be used so that it automatically snaps over the edge of the lever when the lever is pressed down. To open the latch, it only needs to be pushed back slightly against its spring action to release the lever.

Da die Muffe wegen des Durchgreifens des Rückschlagventils nicht mit dem Gehäuse verschraubt werden kann, andererseits aber eine feste, einteilige Verbindung mit dem Gehäuse geschaffen werden muß, wird vorgeschlagen, die Muffe auf das Gehäuse aufzuprellen und gegebenenfalls gegen Verdrehen durch eine Schraube zu sichern. Der Prellverschluß besteht dabei aus mehreren Rillen und gegenüberliegenden, ineinandergreifenden, entsprechenden Nuten.Since the sleeve cannot be screwed to the housing due to the gripping through of the check valve, but on the other hand a solid, one-piece connection must be created with the housing, it is proposed to bounce the sleeve onto the housing and, if necessary, to secure it against rotation by a screw. The impact lock consists of several grooves and opposite, interlocking, corresponding grooves.

Die zum Aufziehen der Muffe auf die Rillung notwendige Querschnittsvergrößerung wird neuerungsgemäß in eleganter Weise dadurch möglich, daß die Schlitze der Gabelaufnahmen im Gehäuse nach unten offen sind, so daß diejenigen der Muffe oben und unten geschlossen sein können, um den erforderlichen hochfesten Verbund zu gewährleisten.The cross-sectional enlargement necessary for pulling the sleeve onto the groove is made possible in an elegant manner by the fact that the slots of the fork receptacles in the housing are open at the bottom, so that those of the sleeve can be closed at the top and bottom in order to ensure the required high-strength bond.

Anhand der beiliegenden Figuren wird die vorliegende Neuerung näher erläutert.

Figur 1: Der Zapfer besteht aus einem Gehäuse 1 mit rundem Querschnitt sowie einer in diesem angeordneten, über den Griff 5 betätigbaren Luftpumpe mit Pumpventil 8 und Pumpgestänge 26. Das Gehäuse besitzt gegenüberliegende Ausnehmungen 16, in der der Bügel 15 mit Absperrventil 19 und Auslauf 18 zusammen mit der Ventilöffnungsstange 3 vertikal bewegt werden können. Der Bügel 15 ist fest mit der Ventilöffnungsstange 3 verbunden, in der der Flüssigkeitsdurchlauf 7 liegt und der an den Flüssigkeitskanal des Bügels 15 angeschlossen ist. Figure 1: The tapper consists of a housing 1 with a round cross-section and an air pump with a pump valve 8 and a pump rod 26 arranged therein, which can be actuated via the handle 5. The housing has opposite recesses 16 in which the bracket 15 with a shut-off valve 19 and outlet 18 can be moved vertically together with the valve opening rod 3. The bracket 15 is fixedly connected to the valve opening rod 3, in which the liquid passage 7 lies and which is connected to the liquid channel of the bracket 15.

Figur 2 : Im unteren Ende des Gehäuses 1 befindet sich ein Einsatz 2, der in dazu im Einsatz vorgesehenen Stegen angeordnete Bohrungen aufweist (nicht gezeigt), in die an einer Gabel 9 innenliegende, endseitig angeordnete Zapfen 6 eingreifen und so das ortsfeste Schwenklager für den Hebel 10 bilden. Die Gabel 9 durchgreift dabei zum Hebel hin angeordnete axial verlaufende Schlitze, über die der Hebel montiert werden kann. Figure 2: In the lower end of the housing 1 there is an insert 2, which has bores arranged in the ridges provided for this purpose (not shown), into which pins 6 located on the inside at a fork 9 engage, and thus the fixed pivot bearing for the Form lever 10. The fork 9 passes through axially extending slots towards the lever, via which the lever can be mounted.

Die Ventilöffnungsstange 3 besitzt nahe des fest gelagerten Zapfens 6 obere und untere angeformte Flansche 11 und 11', zwischen die wiederum entsprechend an der Gabel je gegenüber- und innenliegend eigene Zapfen 6' eingreifen und über die die Kraft zum Heben und Senken der Ventilöffnungsstange 3 auf die Flansche bzw. die Stange übertragen wird, die unten das Ventilöffnungselement für das Keg trägt.The valve opening rod 3 has, near the fixed journal 6, upper and lower molded flanges 11 and 11 ', between which, in turn, corresponding pins 6' engage each other on the fork and on the inside and via which the force for lifting and lowering the valve opening rod 3 is applied the flanges or the rod is transmitted, which carries the valve opening element for the keg below.

Gegen den Pumpenraum 29 ist der Einsatz 2 über einen außenliegenen O-Ring 25' und einen die Ventilöffnungsstange umfassenden Teller 30 sowie in diesem liegenden, inneren O-Ring 25'' abgedichtet. Das mit der Pumpe verbundene Rückschlagventil 12 steckt in einer Aufnahme 20 des Einsatzes 2, die zwischen den Gabelschenkeln angeordnet ist. Das Rückschlagventil 12 ragt in eine Hülse 27 und ist dort abgedichtet gehalten und über deren untere Öffnung mit dem Keg-Ventil verbindbar.The insert 2 is sealed against the pump chamber 29 by means of an outer O-ring 25 'and a plate 30 encompassing the valve opening rod, as well as an inner O-ring 25''located therein. The check valve 12 connected to the pump is in a receptacle 20 of the insert 2, which is arranged between the fork legs. The check valve 12 projects into a sleeve 27 and is kept sealed there and can be connected to the keg valve via its lower opening.

Diese Hülse 27 ist Teil einer auf das Gehäuse 1 aufprellbaren Muffe 13, die am unteren freien Ende die Befestigungsmittel (eingängiges Grobgewinde) für die Anbringung des Zapfers auf dem Keg trägt. Dazu besitzt die Muffe eine zentrale, angeformte, koaxiale Hülse 24, in denen das untere Ende der Ventilöffnungsstange gegen Druckverlust aus dem Keg mit Hilfe zweier O-Ringe 25 abgedichtet ist.This sleeve 27 is part of a sleeve 13 which can be pushed onto the housing 1 and which carries the fastening means (coarse thread) at the lower free end for attaching the tap to the keg. For this purpose, the sleeve has a central, integrally formed, coaxial sleeve 24, in which the lower end of the valve opening rod is sealed against pressure loss from the keg with the aid of two O-rings 25.

Die Muffe 13 einerseits ist übergriffen von einem Ring 21, ebenfalls aus Kunststoff, an den der federnde Riegel 22 angeformt ist, der zwischen die Gabelzinken 9 greift und mit seiner Nase 28 über die Kante 23 des Hebels 10 diesen in der unteren Stellung sichert, wie strichliert dargestellt ist.The sleeve 13 is overlapped on the one hand by a ring 21, also made of plastic, to which the resilient latch 22 is formed, which engages between the fork prongs 9 and secures the latter in the lower position with its nose 28 via the edge 23 of the lever 10, such as is shown in dashed lines.

Das gesamte Gehäuse ist damit aus fest miteinander verbundenen Teilen einstückig aufgebaut und in der Lage, die Hebelkräfte aufzunehmen und auf das zu öffnende Ventil des Kegs zu übertragen.The entire housing is thus constructed in one piece from firmly connected parts and is capable of absorbing the lever forces and transmitting them to the openable valve of the keg.

Der Hebelmechanismus ist innenliegend und verletzungsungefährlich.The lever mechanism is internal and not dangerous to injuries.
