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, which have a holding flange and a coaxial extraction valve and an external thread with a diameter D1 for fitting burners, which are equipped with an adjusting valve for the burner output, the coupling piece having a drilled threaded connection with one of the Have external threads of the small gas bottle complementary internal thread, a pierced pressure piece for opening the sampling valve and a clamping ring, which is divided into sectors that can be clamped against the retaining flange by means of a screw cap with a truncated cone surface.

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 non-detachably connected to the respective burner, so that only burners can be used for the small gas bottles in question which have an internal thread within the coupling piece which matches the external thread of the small gas bottle. On the one hand, the burners in question are not with others Gas sources connectable, and the known small gas bottles can not be equipped with burners that have other coupling threads.

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 specifying a coupling piece of the type described at the outset, which fits the standardized small gas cylinders and actuates their removal valve, but also enables the connection of the small gas cylinders to burners with a different design.

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 problem is solved in the coupling piece specified at the outset according to the invention in that the threaded connector has at its end facing away from the internal thread a pierced transition piece which carries an external thread with a diameter D2 which is larger than the diameter D1 of the external thread of the small gas bottle.

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 enables the use of burners that are not exclusively intended for the known small gas cylinders, for example also for burners that do not necessarily have a metric thread. Couplings of this type, which can be produced cheaply as mass products, on the other hand enable the optional use of small gas cylinders which are not matched to one another.

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 is connected to the threaded connector via a threaded connection, which is made non-detachable, for example by gluing. This makes production easier, and the transition piece and the threaded connector represent an inseparable unit.

Es ist weiterhin von Vorteil, 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 also advantageous if the transition piece between the screw cap and its own external thread has a flange with a polygonal outer surface, which is used to attach a tool is provided. This polygon is preferably a hexagon for attaching a wrench. This allows the coupling piece to be tightly connected to the burner, with which it remains connected as long as the burner is to be used for the same small gas cylinders.

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 of the transition piece facing away from the screw cap is designed as an annular surface for compressing a seal which lies between the burner and the transition piece.

Ein Ausführungsbeispiel des Erfindungsgegenstandes wird nachstehend anhand der Figuren 1 und 2 näher erläutert.An embodiment of the subject matter of the invention is explained below with reference to Figures 1 and 2.

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 burner 1 is shown, which has a handle part 2 and a burner tube 3, which is connected to the handle part via an adjusting valve 4. The burner works according to the so-called Bunsen principle, ie gas flows through a burner nozzle (not shown here) into the burner tube 3, to which ambient air is admixed by the injection effect of the gas jet via the suction openings 5. The adjustment valve 4 is adjustable via a knurled knob 6 and thus the so-called burner output.

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.A pushbutton 7 is arranged laterally in the grip part 2 and actuates a main valve (not shown here) and a piezo igniter (also not shown). The main valve is closed as long as the push button is in the position shown. By pressing the pushbutton 7, the main valve is opened and an ignition spark is transmitted to the burner tube 3, which ignites a flame when the adjusting valve 4 is open. The ignition spark is transmitted through a line which runs in a protective tube 8 and is connected to an electrode arranged in the burner tube 3. The push button 7 can be locked in the inserted state by pressing in a locking button 9 so that the main valve remains open. When the pushbutton 7 is pressed again, the locking button 9 is released and jumps out of the handle part 2 in a direction parallel to the burner tube 3. The pushbutton 7 then moves under spring force into the pushed-out position according to FIG. 1, as a result of which the main valve is closed and the burner flame goes out. At the end facing away from the burner tube 3, the grip part has an internal thread 10 with the diameter D2. The burner described above is state of the art and is therefore not further explained.

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 core of the invention is a coupling piece 11 which is screwed into the internal thread 10 and which connects the burner to a small gas bottle 12, which is also state of the art. The small gas bottle 12 has a holding flange 13 and a coaxial removal valve 14 which is surrounded by an external thread 15 which also belongs to the small gas bottle 12. This external thread has a diameter D1.

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.The coupling piece 11 includes an axially pierced threaded connector 16 with an internal thread 17 which is complementary to the external thread 15 of the small gas bottle 12 and a pressure piece 18 which is also coaxially pierced therewith for opening the removal valve 14. The pressure piece 18 holds the removal valve 14 in the open position as long as that Coupling piece 11 is connected to the small gas bottle 12. For this reason it will Appropriately leave the coupling piece on the burner 1 so that the fuel gas cannot escape from the small gas bottle as long as the pushbutton 7 of the burner 1 is not actuated and the main valve is thereby opened.

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 small gas bottle 12, the coupling piece 11 has a clamping ring 19 known per se, which is divided into sectors 20 by a plurality of slots distributed equidistantly on the circumference, which can be clamped against the holding flange 13 by means of a screw cap 21. For this purpose, the screw cap 21 is provided with a truncated cone surface 21a which presses the sectors 20 against the holding flange 13. This radial pressing of the sectors 20 onto the holding flange 13 takes place by means of an axial movement component of the screw cap 21, which is indirectly connected to the threaded connector 16 via an actuating thread 22. This type of attachment or support of a burner with respect to a gas bottle is also known from the prior art specified at the outset.

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 connector 16 is screwed at its end facing away from the internal thread 17 to a pierced transition piece 23 by means of a threaded connection 24, which is made non-detachable after assembly, for example by gluing. The pierced transition piece 23 has an external thread 23a with a diameter D2, which is significantly larger than the diameter D1 of the external thread 15 of the small gas bottle 12.

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 screw cap 21 and the external thread 23a of the transition piece 23, a flange 25 with a polygonal outer surface 26 is arranged, which is used for attaching a tool in order to screw the coupling piece 11 firmly to the burner 1.

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.To produce the necessary seal, the transition piece 23 is on its end face 27 facing the burner 1 as an annular surface formed on which a sealing ring 28 rests. The handle part 2 of the burner 1 has a circular ring surface which is suitable for this and is not described in any more detail. In the center of the circular ring surface of the grip part 2 there is a pierced pipe socket 29 with a tapered extension 30 which engages in a complementary bore of the threaded socket 16.

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 Kleingasflasche 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 and that the various axial bores of the individual parts are connected in series, so that the fuel gas can flow out of the small gas bottle 12 as long as the coupling piece 11 is firmly connected to the small gas bottle 12 and the adjusting valve 4 and the main valve, not numbered, are open. Other seals that are made of elastomeric materials are not specified. The coupling piece 11 performs two functions: It can be connected to an equally standard burner 1, which is not designed for standardized small gas cylinders 12, for an unlimited period of time. However, its pressure piece 18 also extends the function of this burner 1, namely by causing the otherwise not possible opening of the extraction valve 14 of the small gas bottle 12.
