Abstract

The lamp consists of a liquid container (FB) made of plastic and of a mounted metal holder (MH) for receiving the wick (D). The metal holder (MH) is mounted or pressed to the liquid container (FB), and the lamp is thus produced as a one-way lamp. In order to improve the optical impression, it is surrounded by a decorative shell (ZH) which also covers the metal holder (MH). The lamp remains transportable even after use has commenced, and is protected against spillage when not in use, since a covering jacket can be screwed onto the metal holder (MH) by means of a thread. It covers the wick (D) and the ventilation holes arranged therearound. <IMAGE>

Description

Die Erfindung betrifft eine Leuchte für flüssigen Brennstoff, die aus einem Flüssigkeitsbehälter besteht, in den ein Docht von einer obenliegenden Dochtöffnung aus eingehängt ist.The invention relates to a lamp for liquid fuel, which consists of a liquid container in which a wick is suspended from an overhead wick opening.

Eine derartige Leuchte wird in dem DE-GM 84 26 342 beschrieben. Diese Leuchten werden als Ersatz für Kerzen verwendet, da sie länger brennen und keine Verschmutzungsgefahr durch tropfendes Wachs besteht. Der Behälter ist im Fließpreß- oder Tiefziehver­fahren als Metallkartusche hergestellt. Der Docht wird von auf­gebogenen Spitzen des Behälters in der Öffnung gehalten. Da diese Öffnung sehr klein ist, muß bei der Herstellung der Leuchte der Behälter erst von unten befüllt und anschließend der Boden ein­gesetzt werden. Beim Stanzen der Öffnung und Einsetzen des Doch­tes muß sorgsam vorgegangen werden, um den Brennstoff nicht zu verschütten. Besonders die Metallkartusche ist aufwendig und teuer zu produzieren.Such a lamp is described in DE-GM 84 26 342. These lights are used as a replacement for candles because they burn longer and there is no risk of contamination from dripping wax. The container is manufactured as a metal cartridge using the extrusion or deep-drawing process. The wick is held in the opening by bent tips of the container. Since this opening is very small, the container must first be filled from below when the luminaire is manufactured and then the bottom must be inserted. When punching the opening and inserting the wick, care must be taken not to spill the fuel. The metal cartridge in particular is complex and expensive to produce.

Die US 4,025,290 zeigt eine Leuchte, deren Behälter durch eine mehrteilige Kappe verschlossen ist. Erst wird ein röhrchenarti­ger Brenner aufgesetzt, durch den ein Docht eingefädelt und von einer aufgesetzten Dochthalterung befestigt wird. Somit ist ein zusätzlicher Arbeitsgang notwendig, um nach der Montage des Brenners auf dem Flüssigkeitsbehälter den Docht einzuführen und mit der Halterung aufzusetzen.The US 4,025,290 shows a lamp, the container is closed by a multi-part cap. First a tube-like burner is put on, through which a wick is threaded and fastened by an attached wick holder. An additional operation is therefore necessary in order to insert the wick and mount it with the holder after the burner has been installed on the liquid container.

Der Erfindung liegt die Aufgabe zugrunde, die Herstellung und den Zusammenbau der Leuchte zu erleichtern.The invention has for its object to facilitate the manufacture and assembly of the lamp.

Dies wird gemäß Patentanspruch 1 dadurch erreicht, daß der Flüs­sigkeitsbehälter aus Kunststoff besteht und zur Fixierung des Dochtes eine Metallhalterung mit Stutzen zur Aufnahme der Docht­öffnung am Oberteil des Flüssigkeitsbehälers unlösbar aufgesetzt ist. Da die Metallhalterung des Dochtes eine nichtentflammbare Um­hüllung bildet, können die Kosten der Leuchte durch die Verwen­dung eines Kunststoffbehälters gesenkt werden. Bei unsachge­mäßer Handhabung der Leuchte, insbesondere in öffentlichen Lokalen, wird die Brandgefahr wie bei der Verwendung einer Me­tallkartusche in Grenzen gehalten. Der Zusammenbau der Leuchte kann so erfolgen, daß die Metallhalterung in einem unabhängigen Arbeitsgang gefertigt und der Docht eingesetzt wird. In den be­füllten Flüssigkeitsbehälter ist diese Einheit nurmehr einzu­setzen und abzudichten.This is achieved according to claim 1 in that the liquid container is made of plastic and a metal holder with a socket for receiving the wick opening on the upper part of the liquid container is permanently attached to fix the wick. Since the metal holder of the wick forms a non-flammable covering, the cost of the lamp can be reduced by using a plastic container. If the luminaire is handled improperly, especially in public places, the risk of fire is limited, as when using a metal cartridge. The lamp can be assembled so that the metal bracket is manufactured in an independent process and the wick is inserted. This unit is only to be inserted and sealed in the filled liquid container.

Das Aufsetzen und Verschweißen oder Verpressen der Metallhalte­rung mit dem Flüssigkeitsbehälter wird dadurch erleichtert, daß an der Verbindungsstelle zur Metallhalterung eine Aufsteckrastung oder eine Führungsnut am Oberteil des Flüssigkeitsbehälters an­geformt ist. Der Docht ist dadurch besser fixierbar, daß der Stutzen konisch zulaufend ausgebildet und durch sein Inneres ein sich von unten nach oben verjüngendes Längsrohr gebildet ist. Durch die sich nach obenhin verjüngende Form des Längsrohres entsteht während des Brennens ein Kamineffekt, der das Saugver­halten des Dochtes verbessert. Die Flamme flackert weniger und erzeugt weniger Ruß. Das flackerfreie Licht ist für die Augen angenehmer.The fitting and welding or pressing of the metal holder to the liquid container is facilitated in that a push-on catch or a guide groove is formed on the upper part of the liquid container at the connection point to the metal holder. The wick can be fixed better in that the socket is conically tapered and a longitudinal tube tapering from bottom to top is formed through its interior. The tapered shape of the longitudinal tube creates a chimney effect during firing, which improves the wicking behavior of the wick. The flame flickers less and produces less soot. The flicker-free light is easier on the eyes.

Um beim Transport oder Nichtgebrauch ein Verschmutzen des Dochtes und/oder ein Ausrinnen des Brennstoffes zu verhindern, ist eine die obere Brenneröffnung abschließende Abdeckhülse vorhanden. Die konische Stutzenform oder eine konische Form der Abdeckhülse ge­währleistet beim Wiederverschließen eine besonders gute Abdich­tung. Eine Abdeckhülse aus Metall kann auch zum Abdämpfen der Flamme verwendet werden. Zur besseren Fixierung ist im unteren Teil des Stutzens außen ein Gewinde zum Aufschrauben der Abdeck­hülse vorhanden.In order to prevent the wick from becoming dirty and / or the fuel from escaping during transport or when not in use, a cover sleeve is provided which closes the upper burner opening. The conical socket shape or a conical shape of the cover sleeve ensures a particularly good seal when reclosing. A metal cover sleeve can also be used to dampen the flame. For better fixation, there is a thread in the lower part of the socket for screwing on the cover sleeve.

Um den optischen Eindruck der Leuchte zu verbessern, ist der Flüssigkeitsbehälter mit der Metallhalterung von einer Zierhülle umgeben. Dadurch wird nach dem Verbrauchen des Brennstoffes nur der Flüssigkeitsbehälter gewechselt, eine teure und aufwendig gestaltete Zierhülle kann weiterverwendet werden. Zur Verlänge­rung der Brenndauer der Leuchte ist der Docht dünn ausgeführt.In order to improve the visual impression of the lamp, the liquid container with the metal holder is from a decorative cover surround. As a result, only the liquid container is changed after the fuel has been used up, and an expensive and elaborately designed decorative cover can continue to be used. The wick is thin to extend the burning time of the lamp.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dar­gestellt. Die Figur zeigt den Aufriß des Ausführungsbeispieles.In the drawing, an embodiment of the invention is shown. The figure shows the elevation of the embodiment.

Die Figur zeigt eine Leuchte, die aus einem Flüssigkeitsbehälter FB besteht, in den ein flüssiger Brennstoff eingefüllt ist. Als Brennstoff wird ein speziell gereinigtes Brennöl verwendet, in das ein Docht D getaucht ist. Der Docht D ist in den Stutzen S einer Metallhalterung MH eingeführt, die oben auf den Flüssig­keitsbehälter FB aufgeschweißt ist.The figure shows a lamp that consists of a liquid container FB, in which a liquid fuel is filled. A specially cleaned fuel oil is used as fuel, in which a wick D is immersed. The wick D is inserted into the socket S of a metal holder MH, which is welded onto the liquid container FB at the top.

Die Metallhalterung MH besteht aus Aluminium und hat im Inneren des Stutzens S ein konisches, sich nach obenhin verjüngendes Längsrohr ausgebildet. Es dient der Aufnahme des Dochtes D. Die Metallhalterung MH ist aus einem Stück hergestellt, und die Brenneröffnung auf der Oberseite des Stutzens S ist anfänglich verschlossen. Zum Einführen und Fixieren des Dochtes D wird ein Kreuzschlitz durchgestanzt. Dabei werden auch Belüftungslöcher in die durch den Kreuzschlitz gebildeten Quadranten gestochen. Zur Bildung der Öffnung werden die Ecken am Mittelpunkt des Kreuz­schlitzes aufgebogen. Der Stutzen S weist in seinem Unterteil ein Gewinde G auf, damit eine Abdeckhülse aufgeschraubt werden kann. Sie ist konisch ausgebildet und verschließt sowohl die Brenner­öffnung, als auch die Belüftungslöcher. Weiters ist der Stutzen S von einem wulstartigen Kragen K und einer Einsenkung umgeben, von der allfällige Brennstofftropfen oder Schmutzteilchen, beispiels­weise von einem Streichholz, aufgefangen werden. Darüberhinaus wird dadurch auch die Oberfläche der Metallhalterung MH ver­größert. Das bewirkt einen zusätzlichen Kühleffekt, und die Me­tallhalterung MH kann beim Brennen der Leuchte nicht überhitzt werden.The metal bracket MH is made of aluminum and has a conical longitudinal tube tapering towards the inside of the connector S. It serves to hold the wick D. The metal holder MH is made in one piece and the burner opening on the top of the nozzle S is initially closed. A cross recess is punched through for inserting and fixing the wick D. Ventilation holes are also made in the quadrants formed by the cross recess. To form the opening, the corners are bent open at the center of the cross recess. The socket S has a thread G in its lower part so that a cover sleeve can be screwed on. It is conical and closes both the burner opening and the ventilation holes. Furthermore, the socket S is surrounded by a bead-like collar K and a depression from which any fuel drops or dirt particles, for example a matchstick, are collected. In addition, this also increases the surface area of the metal bracket MH. This creates an additional cooling effect and the metal bracket MH cannot be overheated when the lamp is burning.

Der Flüssigkeitsbehälter FB ist zylindrisch geformt. Als Material wird ein durchsichtiger Kunststoff verwendet. So kann der Be­nutzer der Leuchte auf einfache Weise feststellen, wieviel Brenn­stoff sich noch darin befindet. Die Metallhalterung MH wird auf einen Hals des Flüssigkeitsbehälters FB aufgesetzt, der einen an die Form des Kragens K angepaßten Wulst aufweist. Der Kragen K wird mit dem Wulst dicht verpreßt. Zur Verschönerung kann eine kerzenartige Zierhülle ZH über Metallhalterung MH und Flüssig­keitsbehälter FB gestülpt werden. Der Flüssigkeitsbehälter FB ist nicht nachfüllbar und muß durch einen neuen ersetzt werden, wenn der Brennstoff verbraucht ist. Die Zierhülle ZH, die kunstvoll ausgestaltet sein kann, bleibt erhalten und wird wieder über den neuen Flüssigkeitsbehälter FB gestülpt. Dadurch ist der Flüssig­keitsbehälter FB bei Gebrauch der Leuchte nicht sichtbar und auf seine optische Gestaltung muß kein Wert gelegt werden. Er kann aus billigem Material hergestellt und aus einem oder mehreren Teilen zusammengeklebt werden. Um das fabriksmäßige Befüllen des Flüssigkeitsbehälters FB zu erleichtern, kann sich die Öffnung zur Aufnahme der Metallhalterung MH in einer trichterförmigen Mulde befinden. Der Docht D verbraucht sich durch Brennen nicht und muß auch nicht nachgezogen werden. Er ist bis zum oberen Ende der Metallhalterung MH durchgesteckt und reicht bis zum Boden des Flüssigkeitsbehälters FB.The liquid container FB is cylindrical. A transparent plastic is used as the material. So the user of the lamp can easily determine how much fuel is still in it. The metal holder MH is placed on a neck of the liquid container FB, which has a bead adapted to the shape of the collar K. The collar K is pressed tightly with the bead. For embellishment, a candle-like decorative cover ZH can be put over metal holder MH and liquid container FB. The liquid container FB cannot be refilled and must be replaced by a new one when the fuel is used up. The decorative cover ZH, which can be artistically designed, is retained and is slipped back over the new liquid container FB. As a result, the liquid container FB is not visible when the luminaire is in use and no importance has to be attached to its optical design. It can be made of cheap material and glued together from one or more parts. In order to facilitate the factory filling of the liquid container FB, the opening for receiving the metal holder MH can be located in a funnel-shaped depression. The wick D is not consumed by burning and does not have to be retightened. It is pushed through to the upper end of the metal bracket MH and extends to the bottom of the liquid container FB.
