Abstract
Description
Die Erfindung betrifft ein Kupplungsstück für Kleingasflaschen, die einen Halteflansch und ein hierzu koaxiales Entnahmeventil und ein Außengewinde mit einem Durchmesser D1 für das Aufsetzen von Brennern aufweisen, die mit einem Einstellventil für die Brennerleistung ausgestattet sind, wobei das Kupplungsstück einen durchgebohrten Gewindestutzen mit einem zu dem Außengewinde der Kleingasflasche komplementären Innengewinde, ein durchbohrtes Druckstück für das Öffnen des Entnahmeventils und einen Klemmring aufweisen, der in Sektoren unterteilt ist, die mittels einer Schraubkappe mit einer Kegelstumpffläche gegen den Halteflansch verspannbar sind.The invention relates to a coupling piece for small gas cylinders, the one Holding flange and a coaxial extraction valve and an external thread having a diameter D1 for the placement of burners that are equipped with a control valve for the burner output, whereby the Coupling a drilled threaded connector with one to the External thread of the small gas bottle complementary internal thread pierced pressure piece for opening the sampling valve and one Have clamping ring, which is divided into sectors that by means of a Screw cap with a truncated cone surface against the retaining flange are braced.
Derartige Kupplungsstücke sind bekannt; sie sind unlösbar mit dem jeweiligen Brenner verbunden, so daß für die betreffenden Kleingasflaschen jeweils nur Brenner verwendbar sind, die innerhalb des Kupplungsstücks ein Innengewinde aufweisen, das zu dem Außengewinde der Kleingasflasche passend ist. Die betreffenden Brenner sind einerseits nicht mit anderen Gasquellen verbindbar, und die bekannten Kleingasflaschen können nicht mit Brennern ausgestattet werden, die andere Kupplungsgewinde aufweisen.Couplings of this type are known; they are insoluble with the respective Burner connected so that only for the small gas bottles in question Burners are usable within the coupling piece Have internal thread that to the external thread of the small gas bottle is appropriate. On the one hand, the burners in question are not with others Gas sources connectable, and the known small gas bottles can not Burners that have different coupling threads.
Durch die EP 0 221 259 A1 ist es bekannt, einen kompletten Gasbrenner mit Einstellventil und Zündelektrik mittels zweier unterschiedlicher formschlüssiger Verbindungselemente entweder unter Ausnutzung jeweils eines Verbindungselements mit unterschiedlichen Anschlüssen verschiedener Flüssiggasflaschen zu verbinden oder unter gleichzeitiger Ausnutzung beider formschlüssiger Verbindungselemente mit zwei Anschlüssen ein und derselben Flüssiggasflasche, die zwei entsprechende komplementäre Anschlußelemente aufweist. Solche Flüssiggasflaschen sind als Kleingasflaschen genormt im Handel. Das eine Verbindungselement des Gasbrenners besteht dabei aus einem Innen-Feingewinde, das andere Verbindungselement aus einem elastomeren Ring mit Federzungen und aus einem Spannring mit einer konischen Innenfläche, die auf die Federzungen einwirkt. Die bekannte Kupplung ist jedoch weder dafür vorgesehen noch geeignet, mit kompletten Gasbrennern unterschiedlicher Herkunft und mit unterschiedlichen Anschlußelementen und -maßen verbunden zu werden.EP 0 221 259 A1 discloses a complete gas burner with adjusting valve and ignition electronics using two different positive locking Fasteners either using each a connecting element with different connections different To connect liquefied gas cylinders or with simultaneous use both positive connection elements with two connections one and the same liquid gas bottle, the two corresponding complementary Has connection elements. Such LPG bottles are as small gas bottles standardized in trade. One connecting element of the gas burner consists of an internal fine thread, the other connecting element from an elastomer ring with spring tongues and from a clamping ring with a conical inner surface, which on the spring tongues acts. However, the known clutch is neither intended for this nor suitable with complete gas burners of different origins and with different connection elements and dimensions to be connected.
Durch die nicht vorveröffentlichte WO 96/02791 ist es Stand der Technik, einen Adapter für den Anschluß von öfen, Gaslaternen o. dgl. an unterschiedliche Flüssiggasflaschen dadurch herzustellen, daß man einen Ventilkörper, ggf. mit einer Zündelektrik, für den Anschluß an die Öfen, Gaslaternen o. dgl. permanent mit einem Hohlkörper verbindet, der an seinem unteren Ende ein Anschlußelement für die Verbindung mit der Flüssiggasflasche besitzt. Die permanente Verbindung erfolgt durch einen plastischen Verformungsvorgang von Zungen zwischen dem Ventilkörper und dem Hohlkörper und ist nicht mehr lösbar. Dieser Adapter ist wegen seiner Ventils aufwenig und nach seiner Verbindung nur noch für die Verbindung jeweils des gleichen Verbrauchertyps mit dem gleichen Gasflaschentyp verwendbar.Due to the unpublished WO 96/02791 it is state of the art an adapter for connecting ovens, gas lanterns or the like to different To produce liquefied gas cylinders by one Valve body, if necessary with an electrical system, for connection to the furnaces, Gas lanterns or the like permanently connects to a hollow body that is attached its lower end a connector for connection to the Owns LPG bottle. The permanent connection is made by a plastic deformation process of tongues between the valve body and the hollow body and is no longer detachable. This adapter is due of its valve and after its connection only for Connection of the same consumer type to the same Gas bottle type usable.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Kupplungsstück der eingangs beschriebenen Gattung anzugeben, das zu den genormten Kleingasflaschen paßt und deren Entnahmeventil betätigt, aber auch die Verbindung der Kleingasflaschen mit anders ausgestatteten Brennern ermöglicht.The invention is therefore based on the object of a coupling piece Specify the genus described above, which to the standardized Small gas bottles fit and operate their extraction valve, but also the Connection of the small gas cylinders with differently equipped burners allows.
Die Lösung der gestellten Aufgabe erfolgt bei dem eingangs angegebenen Kupplungsstück erfindungsgemäß dadurch, daß der Gewindestutzen an seinem dem Innengewinde abgekehrten Ende ein durchbohrtes Übergangsstück aufweist, das ein Außengewinde mit einem Durchmesser D2 trägt, der größer ist als der Durchmesser D1 des Außengewindes der Kleingasflasche.The solution to the problem is the one specified at the beginning Coupling piece according to the invention in that the threaded connector a pierced end facing away from the internal thread Has transition piece that has an external thread with a diameter D2 carries, which is larger than the diameter D1 of the external thread Small gas cylinder.
Ein derartiges Kupplungsstück ermöglicht den Einsatz von Brennern, die nicht ausschließlich für die bekannten Kleingasflaschen vorgesehen sind, beispielsweise also auch für Brenner, die nicht unbedingt ein metrisches Gewinde aufweisen. Derartige Kupplungsstücke, die billig als Massenprodukte herstellbar sind, ermöglichen die wahlweise Verwendung von Kleingasflaschen andererseits, die nicht aneinander angepaßt sind.Such a coupling piece allows the use of burners that are not are intended exclusively for the known small gas cylinders, for example for burners that are not necessarily metric Have threads. Such coupling pieces, which are cheap as mass products are producible, allow the optional use of Small gas cylinders, on the other hand, which are not adapted to each other.
Es ist dabei von besonderem Vorteil, wenn das Übergangsstück über eine Gewindeverbindung mit dem Gewindestutzen verbunden ist, die unlösbar gemacht wird, beispielsweise durch Verkleben. Dadurch wird die Herstellung erleichtert, und das Übergangsstück und der Gewindestutzen stellen eine untrennbare Baueinheit dar.It is particularly advantageous if the transition piece has a Threaded connection is connected to the threaded connector, which is unsolvable is made, for example by gluing. This will make it relieved, and the transition piece and the threaded connector provide one inseparable unit.
Es ist weiterhin von wenn das Übergangsstück zwischen der Schraubkappe und seinem eigenen Außengewinde einen Flansch mit einer polygonalen Außenfläche besitzt, der zum Ansetzen eines Werkzeugs versehen ist. Dieses Polygon ist vorzugsweise ein Sechskant für das Ansetzen eines Schraubenschlüssels. Dadurch kann das Kupplungsstück dicht mit dem Brenner verbunden werden, mit dem es solange verbunden bleibt, wie der Brenner für die gleichen Kleingasflaschen verwendet werden soll.It is still from when the transition piece between the Screw cap and its own external thread with a flange has a polygonal outer surface for attaching a tool is provided. This polygon is preferably a hexagon for that Apply a wrench. This allows the coupling piece tightly connected to the burner with which it is connected for as long remains as the burner can be used for the same small gas cylinders should.
Es ist weiterhin von Vorteil, wenn das der Schraubkappe abgekehrte Ende des Übergangsstücks als Ringfläche für das Zusammenpressen einer Dichtung ausgebildet ist, die zwischen dem Brenner und dem Übergangsstück liegt.It is also advantageous if the end facing away from the screw cap of the transition piece as an annular surface for compressing one Seal is formed between the burner and the transition piece lies.
Ein Ausführungsbeispiel des Erfindungsgegenstandes wird nachstehend anhand der Figuren 1 und 2 näher erläutert.An embodiment of the subject invention is below with reference to Figures 1 and 2 explained in more detail.
Es zeigen:

In Figur 1 ist ein Brenner 1 dargestellt, der ein Griffteil 2 und ein Brennerrohr
3 aufweist, das über ein Einstellventil 4 mit dem Griffteil verbunden ist. Der
Brenner arbeitet nach dem sogenannten Bunsen-Prinzip, d.h. durch eine hier
nicht gezeigte Brennerdüse strömt Gas in das Brennerrohr 3, dem durch die
Injektionswirkung des Gasstrahls über die Ansaugöffnungen 5 Umgebungsluft
beigemischt wird. Das Einstellventil 4 ist über einen gerändelten Drehknopf 6
verstellbar und damit die sogenannte Brennerleistung. In Figure 1, a
Im Griffteil 2 ist seitlich eine Drucktaste 7 angeordnet, die ein hier nicht
gezeigtes Hauptventil und einen gleichfalls nicht gezeigten Piezo-Zünder
betätigt. Solange sich die Drucktaste in der gezeichneten Stellung befindet,
ist das Hauptventil geschlossen. Durch Eindrücken der Drucktaste 7 wird das
Hauptventil geöffnet und ein Zündfunke zum Brennerrohr 3 übertragen, der
eine Flamme zündet, wenn das Einstellventil 4 geöffnet ist. Der Zündfunke
wird durch eine Leitung übertragen, die in einem Schutzrohr 8 verläuft und an
eine im Brennerrohr 3 angeordnete Elektrode angeschlossen ist. Die
Drucktaste 7 läßt sich in eingeschobenem Zustand durch das Eindrücken
einer Verriegelungstaste 9 verriegeln, so daß das Hauptventil geöffnet bleibt.
Bei erneutem Drücken der Drucktaste 7 wird die Verriegelungstaste 9
freigegeben und springt aus dem Griffteil 2 in einer Richtung parallel zum
Brennerrohr 3 heraus. Die Drucktaste 7 gelangt hierauf unter Federkraft in die
herausgeschobene Stellung gemäß Figur 1, wodurch das Hauptventil
geschlossen wird und die Brennerflamme erlischt. An dem dem Brennerrohr 3
abgekehrten Ende besitzt das Griffteil ein Innengewinde 10 mit dem
Durchmesser D2. Der zuvor beschriebene Brenner ist Stand der Technik und
wird daher nicht weiter erläutert.In the handle part 2 a push button 7 is arranged on the side, which is not one here
shown main valve and a piezo igniter also not shown
actuated. As long as the push button is in the drawn position,
the main valve is closed. Pressing the pushbutton 7 will

Kern der Erfindung ist ein Kupplungsstück 11, das in das Innengewinde 10
eingeschraubt ist und das den Brenner mit einer Kleingasflasche 12
verbindet, die gleichfalls Stand der Technik ist. Die Kleingasflasche 12 besitzt
einen Halteflansch 13 und ein hierzu koaxiales Entnahmeventil 14, das von
einem gleichfalls zur Kleingasflasche 12 gehörenden Außengewinde 15
umgeben ist. Dieses Außengewinde besitzt einen Durchmesser D1.The essence of the invention is a
Zum Kupplungsstück 11 gehört ein axial durchbohrter Gewindestutzen 16 mit
einem zu dem Außengewinde 15 der Kleingasflasche 12 komplementären
Innengewinde 17 und ein hierzu koaxiales gleichfalls durchbohrtes Druckstück
18 für das Öffnen des Entnahmeventils 14. Das Druckstück 18 hält das
Entnahmeventil 14 solange in geöffneter Stellung, wie das Kupplungsstück 11
mit der Kleingasflasche 12 verbunden ist. Aus diesem Grunde wird das
Kupplungsstück zweckmäßig am Brenner 1 belassen, so daß Brenngas aus
der Kleingasflasche nicht entweichen kann, solange die Drucktaste 7 des
Brenners 1 nicht betätigt und dadurch das Hauptventil geöffnet wird.An axially drilled threaded
Um die Kleingasflasche 12 mechanisch zu entlasten, besitzt das
Kupplungsstück 11 einen an sich bekannten Klemmring 19, der durch eine
Vielzahl von auf dem Umfang äquidistant verteilten Schlitzen in Sektoren 20
unterteilt ist, die mittels einer Schraubkappe 21 gegen den Halteflansch 13
verspannbar sind. Zu diesem Zwecke ist die Schraubkappe 21 mit einer
Kegelstumpffläche 21a versehen, die die Sektoren 20 gegen den Halteflansch
13 preßt. Dieses radiale Anpressen der Sektoren 20 an den Halteflansch 13
geschieht durch eine axiale Bewegungskomponente der Schraubkappe 21,
die über ein Betätigungsgewinde 22 mittelbar mit dem Gewindestutzen 16
verbunden ist. Auch diese Art der Befestigung bzw. Abstützung eines
Brenners gegenüber einer Gasflasche ist durch den eingangs angegebenen
Stand der Technik bekannt.In order to mechanically relieve the
Zum Unterschied vom Stand der Technik ist der Gewindestutzen 16 an
seinem dem Innengewinde 17 abgekehrten Ende mit einem durchbohrten
Übergangsstück 23 mittels einer Gewindeverbindung 24 verschraubt, die
nach dem Zusammenbau unlösbar gemacht wird, beispielsweise durch
Verkleben. Das durchbohrte Übergangsstück 23 besitzt ein Außengewinde
23a mit einem Durchmesser D2, der deutlich größer ist als der Durchmesser
D1 des Außengewindes 15 der Kleingasflasche 12.In contrast to the prior art, the threaded
Zwischen der Schraubkappe 21 und dem Außengewinde 23a des
Übergangsstücks 23 ist ein Flansch 25 mit einer polygonalen Außenfläche 26
angeordnet, die zum Ansetzen eines Werkzeugs dient, um das
Kupplungsstück 11 fest mit dem Brenner 1 zu verschrauben.Between the
Zur Herstellung der notwendigen Abdichtung ist das Übergangsstück 23 an
seiner dem Brenner 1 zugekehrten Stirnseite 27 als Kreisringfläche
ausgebildet, auf der ein Dichtungsring 28 aufliegt. Der Griffteil 2 des Brenners
1 besitzt eine hierfür geeignete, nicht näher bezeichnete Kreisringfläche. Im
Zentrum der Kreisringfläche des Griffteils 2 befindet sich ein durchbohrter
Rohrstutzen 29 mit einem verjüngten Fortsatz 30, der in eine hierzu
komplementäre Bohrung des Gewindestutzens 16 eingreift.The
Es ist erkennbar, daß das gesamte Kupplungsstück rotationssymmetrisch
ausgebildet ist und daß die verschiedenen axialen Bohrungen der einzelnen
Teile in Reihe geschaltet sind, so daß das Brenngas aus der Kteingasflasche
12 solange ausströmen kann, wie das Kupplungsstück 11 fest mit der
Kleingasflasche 12 verbunden und das Einstellventil 4 sowie das nicht
bezifferte Hauptventil geöffnet sind. Weitere Dichtungen, die aus elastomeren
Werkstoffen bestehen, sind nicht näher bezeichnet. Das Kupplungsstück 11
übt dabei zwei Funktionen aus: Es läßt sich mit einem gleichfalls
handelsüblichen Brenner 1, der nicht für genormte Kleingasflaschen 12
ausgebildet ist, auf unbegrenzte Zeit verbinden. Es erweitert durch sein
Druckstück 18 aber auch die Funktion dieses Brenners 1, indem es nämlich
das ansonsten nicht mögliche Öffnen des Entnahmeventils 14 der
Kleingasflasche 12 herbeiführt. Es erweitert dadurch sowohl das
Einsatzgebiet derartiger Kleingasflaschen 12, die in unterschiedlichen Größen
im Handel sind, als auch das Einsatzgebiet von Brennern, die von Haus aus
nicht mit einem Kupplungsstück für derartige Kleingasflaschen versehen sind
und beispielsweise über die üblichen Schläuche an größere Gasflaschen
anschließbar sind.It can be seen that the entire coupling piece is rotationally symmetrical
is formed and that the different axial bores of each
Parts are connected in series so that the fuel gas from the Kteingasottle
