Description

Die Erfindung betrifft einen neuen abnehmbaren Boden eines Feuerzeugs, insbesondere eines Gasfeuerzeugs, mit einer betätigbaren Verriegelung, zum Schutz und zur Abdeckung des Feuerzeug-Nachfüllstutzens, mit einem mit einer Feuerzeughülse zu verbindenden Zwischenboden und einem Federsystem.The invention relates to a new removable base of a lighter, in particular a gas lighter, with an actuatable lock, for protecting and covering the lighter refill, with an intermediate base to be connected to a lighter sleeve and a spring system.

Feuerzeugböden der genannten Art sind bereits bekannt, beispielsweise aus der US-A 1 874219 und der DE-A 27 52 664. Dieses zuletzt genannte Feuerzeug weist einen zweiteiligen Boden auf, bestehend aus einem nicht näher bezeichneten Einsteckteil, welches in die Hülse eingesteckt wird und auf einer Hälfte des Bodens den Abschluss bildet und auf der anderen Hälfte mit Bohrungen zur Aufnahme einiger Elemente versehen ist. Eine Platte, welche die zweite Hälfte des Bodens bildet, ist kipp- und drehbar gelagert. Die Platte verdeckt den Zugang zum Füllmundstück des Ventils und ein Einschnitt gestattet das Verdrehen der Platte, welche in einem Drehlager drehbar und federnd gelagert ist. Dieses bekannte Feuerzeug weist daher weder einen abnehmbaren Boden (von einer Demontage abgesehen), noch einen Zwischenboden auf.Lighter bases of the type mentioned are already known, for example from US-A 1 874219 and DE-A 27 52 664. This last-mentioned lighter has a two-part base, consisting of an insertion part, not specified, which is inserted into the sleeve and forms the end on one half of the floor and is drilled on the other half to accommodate some elements. A plate, which forms the second half of the floor, is tiltable and rotatable. The plate covers the access to the valve's mouthpiece and an incision allows the plate to be rotated, which is rotatably and resiliently mounted in a pivot bearing. This known lighter therefore has neither a removable floor (apart from disassembly) nor an intermediate floor.

Die Böden der bekannten Feuerzeuge sind üblicherweise mit der Feuerzeughülse verschraubt und zur Vereinfachung des Lösens der Verschraubung sind die Schrauben mit Einkerbungen versehen, welche eine solche Grösse aufweisen, dass die Betätigung mit einer Münze erfolgen kann. Ein Feuerzeug jedoch, welches weltweit vertrieben werden soll, müsste unterschiedliche Schlitze aufweisen, da die Münzen in den verschiedenen Ländern unterschiedlich sind und nicht die gleiche Stärke besitzen. Nimmt der Verbraucher eine Münze mit einer nicht geeigneten Stärke, dann wird der Schlitz beschädigt. Dies kann für ein hochwertiges Feuerzeug nicht zugelassen werden. Ferner besteht noch der nicht unwesentliche Nachteil, dass sich die Schrauben unbeabsichtigt lösen können, wodurch der Nachfüllstutzen freigelegt wird und somit verschmutzen kann. Darüberhinaus können die Schrauben verloren gehen.The bases of the known lighters are usually screwed to the lighter sleeve and, to simplify the loosening of the screw connection, the screws are provided with notches which are of such a size that they can be actuated with a coin. However, a lighter that is to be sold worldwide would have to have different slots because the coins in different countries are different and do not have the same strength. If the consumer takes a coin with an unsuitable strength, the slot will be damaged. This cannot be allowed for a high quality lighter. Furthermore, there is the not insignificant disadvantage that the screws can loosen unintentionally, as a result of which the refill nozzle is exposed and can thus become dirty. The screws can also be lost.

Der Erfindung liegt daher die Aufgabe zugrunde hier Abhilfe zu schaffen. Somit besteht die Aufgabe konkret darin, einen abnehmbaren Boden für ein Feuerzeug der oben aufgeführten Art zu schaffen, welcher eine Verriegelung aufweist, die sich ohne Verwendung eines Werkzeugs öffnen und schliessen lässt, wobei sichergestellt ist, dass sich die Verriegelung nicht selbsttätig öffnen kann. Der Boden soll ferner mit der Hülse des Feuerzeugs optisch eine geschlossene Einheit bilden.The invention is therefore based on the object to remedy this. Thus, the concrete task is to create a removable base for a lighter of the type listed above, which has a lock that can be opened and closed without the use of a tool, ensuring that the lock cannot open automatically. The bottom should also form a closed unit with the sleeve of the lighter.

Die Lösung dieser Aufgabe besteht gemäss der Erfindung darin, dass in dem Zwischenboden zwei gegeneinander wirkende Federsysteme exzentrisch zur Mitte des Zwischenbodens angeordnet sind, wobei das eine Federsystem eine um eine Achse einer schwenkbar gelagerten Schwinge geführte Torsionsfeder aufweist, und die Torsionsfeder die Schwinge mit dem Boden in Verriegelungsposition hält, während das zweite Federsystem mit einer auf einen Bolzen wirkenden Spiralfeder versehen ist, und die Spiralfeder über den Bolzen auf den verriegelten Boden eine Kraft ausübt, welche von der Schwinge aufgenommen wird und der Boden eine Bohrung aufweist, deren eine Seite mit einer Schrägfläche entsprechend dem Schwenkradius der Schwinge versehen ist, wobei deren andere Seite eine Stufe aufweist, gegen deren Aussenfläche die Innenfläche einer Nase der Schwinge im verriegelten Zustand der Schwinge anschlägt.According to the invention, this object is achieved in that two counter-acting spring systems are arranged eccentrically to the center of the intermediate floor in the intermediate floor, one spring system having a torsion spring guided about an axis of a pivotally mounted rocker arm, and the torsion spring holding the rocker with the floor holds in the locked position, while the second spring system is provided with a coil spring acting on a bolt, and the coil spring exerts a force on the bolt on the locked bottom, which is received by the rocker and the bottom has a bore, one side of which with a Inclined surface is provided according to the swing radius of the rocker, the other side of which has a step, against the outer surface of which the inner surface of a nose of the rocker strikes in the locked state of the rocker.

In Weiterbildung der Erfindung ist auf der den Federsystemen gegenüberliegenden Seite des Zwischenbodens - bezogen auf die Mitte des Zwischenbodens - eine Bohrung mit einer Hinterdrehung vorhanden, in die die Nase eines mit dem Boden verbundenen Nockens in Verriegelungsposition eingreift.In a further development of the invention, on the side of the intermediate floor opposite the spring systems, with respect to the center of the intermediate floor, there is a bore with a backward rotation into which the nose of a cam connected to the floor engages in the locking position.

Gemäss vorteilhafter Ausführung der Erfindung befinden sich der Bolzen und die auf ihn einwirkende Spiralfeder in einer Bohrung des Zwischenbodens, wobei sich die Spiralfeder gegen ein in der Bohrung befestigtes Gegenlager abstützt und der Bolzen an seinem oberen Ende mit einem Bund versehen ist, der im geöffneten Zustand des Zwischenbodens gegen eine untere Stufe in der Bohrung anschlägt.According to an advantageous embodiment of the invention, the bolt and the spiral spring acting on it are located in a bore in the intermediate floor, the spiral spring being supported against a counter bearing fastened in the bore and the bolt being provided at its upper end with a collar which is in the open state of the intermediate floor strikes against a lower step in the bore.

Durch die zwei gegeneinander wirkenden Federsysteme wird gemäss der Aufgabenstellung der Erfindung sichergestellt, dass das Verriegelungssystem stets fest geschlossen ist, da die Torsionsfeder ständig dafür sorgt, dass die Schwinge in Verriegelungsposition verbleibt. Hierfür weist der Boden in vorteilhafter Weise die genannte Bohrung auf.The two spring systems acting against each other ensure, according to the object of the invention, that the locking system is always firmly closed, since the torsion spring constantly ensures that the rocker remains in the locking position. For this purpose, the base advantageously has the bore mentioned.

Um den Boden in einfacher Weise öffnen zu können, weist die nach aussen gerichtete Fläche der Schwinge eine Einkerbung zur Ausübung einer Tangentialkraft mit Hilfe eines Fingernagels auf.In order to be able to open the base in a simple manner, the outward-facing surface of the rocker has a notch for exerting a tangential force with the aid of a fingernail.

Unmittelbar nach Ausübung einersolchen Tangentialkraft zum Öffnen des Bodens wird das zweite Federsystem aktiv und stösst den Boden einseitig aus der Feuerzeughülse, sobald die Nase der Schwinge die Aussenfläche der Stufe des Bodens durch die sich ergebende Tangentialbewegung frei gibt.Immediately after exerting such a tangential force to open the floor, the second spring system becomes active and pushes the floor out of the lighter sleeve on one side as soon as the nose of the rocker releases the outer surface of the step of the floor by the resulting tangential movement.

In einer weiteren Ausführungsform der Erfindung weist der Boden eine exzentrisch zur Schwinge ausgerichtete Stufen-Bohrung auf, in der ein axial verschieblich gelagerter Bolzen angeordnet ist, welcher mit einem Bund versehen ist, der zur Begrenzung der oberen Bewegung des Bolzens gegen eine in der Stufen-Bohrung befindliche Büchse anschlägt, während die untere Bewegung des Bolzens durch eine Stufe der Stufen-Bohrung begrenzt wird.In a further embodiment of the invention, the base has a stepped bore which is aligned eccentrically to the rocker arm and in which an axially displaceably mounted bolt is arranged, which is provided with a collar which is used to limit the upper movement of the bolt against one in the stepped Bore located stop, while the lower movement of the bolt is limited by a step of the step hole.

Ferner weist bei dieser Lösung der Erfindung der Bolzen eine nach aussen gerichtete Einkerbung auf, welche zur Aufnahme einer Kugelschreiberspitze ausgebildet ist.Furthermore, in this solution of the invention, the bolt has an outward notch, which is designed to receive a ballpoint pen tip.

Zum Öffnen dieser Ausführungsform der Erfindung wird mit einer Kugelschreiberspitze auf die genannte Einkerbung ein Druck ausgeübt, wodurch die Schwinge ihre zuvor beschriebene Funktion ausübt. Da Kugelschreiber mit genormten Spitzen weltweit verbreitet sind, besteht kein Problem einen solchen Schreiber zum Öffnen des Bodens einzusetzen. Es entfällt bei dieser Ausführungsform die in der Schwinge vorgesehene Einkerbung für die Öffnungsbetätigung mit Hilfe eines Fingernagels.To open this embodiment of the invention, pressure is exerted with a ballpoint pen tip on said notch where performs its previously described function through the swing arm. Since ballpoint pens with standardized tips are widespread worldwide, there is no problem using such a pen to open the bottom. In this embodiment, the notch provided in the rocker for opening actuation with the aid of a fingernail is omitted.

Die Erfindung wird anhand der Zeichnungen, in denen zwei Ausführungsbeispiele dargestellt sind, näher erläutert. Hierbei zeigen:

  • Figur 4 einen Querschnitt durch den Zwischenboden und den abnehmbaren Boden gemäss der Ausführungsform nach Figur 3 im geöffneten Zustand;
The invention is explained in more detail with reference to the drawings, in which two exemplary embodiments are shown. Here show:
  • 1 shows a cross section through the intermediate floor and the removable floor according to the invention in the closed state;
  • Figure 2 shows a cross section through the intermediate floor and the removable floor according to the invention in the open state;
  • 3 shows a cross section through the intermediate floor and the removable floor of a further embodiment according to the invention in the closed state, and
  • Figure 4 shows a cross section through the intermediate floor and the removable floor according to the embodiment of Figure 3 in the open state;

Wie aus den Figuren 1 und 2 ersichtlich ist, sind in einem mit der Feuerzeughülse 26 verbundenen Zwischenboden 1 zwei gegeneinander wirkende Federsysteme 2, 3 exzentrisch zur Längsachse 28 des Feuerzeugs angeordnet. Das eine Federsystem 2 weist eine um eine Achse 7 einer schwenkbar gelagerten Schwinge 5 geführte Torsionsfeder 6 auf, welche die Schwinge 5 mit dem Boden 27 in Verriegelungsposition hält, während das zweite Federsystem 3 mit einer auf einen Bolzen 8 wirkenden Spiralfeder 9 versehen ist, wobei die Spiralfeder 9 über den Bolzen 8 auf den verriegelten Boden 27 eine Kraft ausübt, welche von der Schwinge aufgenommen wird.As can be seen from FIGS. 1 and 2, two counter-acting spring systems 2, 3 are arranged eccentrically to the longitudinal axis 28 of the lighter in an intermediate floor 1 connected to the lighter sleeve 26. One spring system 2 has a torsion spring 6 which is guided about an axis 7 of a pivotably mounted rocker 5 and which holds the rocker 5 with the base 27 in the locking position, while the second spring system 3 is provided with a spiral spring 9 acting on a bolt 8, whereby the coil spring 9 exerts a force on the locked base 27 via the bolt 8, which force is absorbed by the rocker arm.

Auf der dem Federsystem 2, 3 gegenüberliegenden Seite des Zwischenbodens 1 - bezogen auf die Längsachse 28 des Feuerzeugs - ist eine Bohrung 20 mit einer Hinterdrehung 30 vorhanden, in die die Nase 19 eines mit dem Boden 27 verbundenen Nockens 18 in Verriegelungsposition eingreift.On the side of the intermediate floor 1 opposite the spring system 2, 3 - with respect to the longitudinal axis 28 of the lighter - there is a bore 20 with a backward rotation 30 into which the lug 19 of a cam 18 connected to the floor 27 engages in the locking position.

Der Bolzen 8 und die auf ihn einwirkende Spiralfeder 9 befinden sich in einer Bohrung 11 des Zwischenbodens 1, wobei sich die Spiralfeder 9 gegen ein in der Bohrung 11 befestigtes Gegenlager 10 abstützt und der Bolzen 8 an seinem oberen Ende mit einem Bund 12 versehen ist, der im geöffneten Zustand des Zwischenbodens 1 gegen eine untere Stufe 13 in der Bohrung 11 anschlägt.The bolt 8 and the spiral spring 9 acting on it are located in a bore 11 in the intermediate floor 1, the spiral spring 9 being supported against a counter bearing 10 fastened in the bore 11 and the bolt 8 being provided with a collar 12 at its upper end, which strikes in the open state of the intermediate floor 1 against a lower step 13 in the bore 11.

Der Boden 27 weist ferner eine Bohrung 4 auf, deren eine Seite mit einer Schrägfläche 31 entsprechend dem Schwenkradius der Schwinge 5 versehen ist, und deren andere Seite eine Stufe 32 aufweist, gegen deren Aussenfläche die Innenfläche einer Nase 16 der Schwinge 5 anschlägt, wie aus der Figur 1 ersichtlich ist.The bottom 27 also has a bore 4, one side of which is provided with an inclined surface 31 corresponding to the swing radius of the rocker 5, and the other side of which has a step 32, against the outer surface of which the inner surface of a nose 16 of the rocker 5 strikes, as from 1 can be seen.

Die nach aussen gerichtete Fläche der Schwinge 5 ist mit einer Einkerbung 34 zur Ausübung einer Tangentialkraft mit Hilfe eines Fingernagels versehen.The outward-facing surface of the rocker 5 is provided with a notch 34 for exerting a tangential force with the aid of a fingernail.

Zur Befestigung und Verriegelung des Bodens 27 mit der Hülse des Feuerzeugs wird dieser mit seinem Nocken 18 in die Bohrung 20 und sodann mit der Nase 19 in die Hinterdrehung 30 geschoben, wie insbesondere aus der Figur 2 zu entnehmen ist. Der Boden 27 wird anschliessend gegen die Kraft der Feder 9 und damit gegen den Bolzen 8 gedrückt, wobei die Schwinge 5 mit ihrer Nase 16 um die abgerundeten Kanten der Stufe 32 des Bodens 27 geführt wird. Die Torsionsfeder 6 der Schwinge 5 übt dabei ständig einen solchen Druck aus, dass beim Anschlag des Bodens 27 an den Zwischenboden 1 die Nase 16 unter die Stufe 32 geschoben wird, so dass damit die Verriegelung des Bodens 27 leicht hörbar eingerastet ist. In dieser Einrastposition ist die Feder 9 des Federsystems 3 maximal gespannt und übt zwischen dem Gegenlager 10 und dem Bund 12 und damit auf den Bolzen 8 einen entsprechenden Druck aus, der diesen auf den Boden 27 überträgt. Damit wird die Aussenfläche der Stufe 32 des Bodens an die Innenfläche der Nase 16 der Schwinge 5 gepresst. Ausserdem wird durch die Wirkung der Torsionsfeder 6 eine in Schliessrichtung weisende Tangentialkraft ausgeübt, so dass durch die gegeneinander wirkenden Federkräfte eine sichere Verriegelung gegeben ist.To fasten and lock the base 27 with the sleeve of the lighter, it is pushed with its cam 18 into the bore 20 and then with the nose 19 into the backward rotation 30, as can be seen in particular from FIG. The base 27 is then pressed against the force of the spring 9 and thus against the bolt 8, the rocker 5 being guided with its nose 16 around the rounded edges of the step 32 of the base 27. The torsion spring 6 of the rocker 5 constantly exerts such a pressure that when the base 27 strikes the intermediate base 1 the nose 16 is pushed under the step 32, so that the locking of the base 27 is easily audibly engaged. In this latching position, the spring 9 of the spring system 3 is maximally tensioned and exerts a corresponding pressure between the thrust bearing 10 and the collar 12 and thus on the bolt 8, which transmits it to the floor 27. So that the outer surface of the step 32 of the floor is pressed against the inner surface of the nose 16 of the rocker 5. In addition, the action of the torsion spring 6 exerts a tangential force pointing in the closing direction, so that a secure locking is provided by the spring forces acting against each other.

Für den Entriegelungsvorgang oder für das Öffnen des Bodens 27 ist es lediglich erforderlich mit dem Fingernagel oder einem entsprechend geformten Gegenstand eine Tangentialkraft entgegen der Wirkung der Torsionsfeder 6 auszuüben. Sobald die gegeneinander drückenden Flächen, nämlich die Aussenfläche der Stufe 32 und die Innenfläche der Nase 16, voneinander frei kommen, hebt sich der Boden 27 durch die Wirkung der Spiralfeder 9 von dem Zwischenboden 1 ab, und kann sodann durch Herausführen des Nokkens 18 aus der Bohrung 20 abgenommen werden.For the unlocking process or for opening the bottom 27, it is only necessary to exert a tangential force against the action of the torsion spring 6 with the fingernail or a correspondingly shaped object. As soon as the surfaces pressing against each other, namely the outer surface of the step 32 and the inner surface of the nose 16, come free from one another, the base 27 lifts off from the intermediate base 1 by the action of the spiral spring 9, and can then be carried out by guiding the cam 18 out of the Hole 20 are removed.

Die Figuren 3 und 4 zeigen eine weitere Ausführungsform der Erfindung. Hierbei weist der Boden 27 eine exzentrisch zur Schwinge 5 ausgerichtete Stufen-Bohrung 21 auf, in der ein axial verschieblich gelagerter Bolzen 22 angeordnet ist, welcher mit einem Bund 23 versehen ist, der zur Begrenzung der oberen Bewegung des Bolzens 22 gegen eine in der Stufen-Bohrung 21 befindliche Büchse 24 anschlägt, während die untere Bewegung des Bolzens 22 durch eine Stufe 25 der Stufen-Bohrung 21 begrenzt wird.Figures 3 and 4 show a further embodiment of the invention. Here, the bottom 27 has an eccentrically aligned to the rocker 5 step bore 21, in which an axially displaceably mounted pin 22 is arranged, which is provided with a collar 23, which limits the upper movement of the pin 22 against one in the steps -Bore 21 abuts bush 24, while the lower movement of the pin 22 is limited by a step 25 of the step hole 21.

Zur Durchführung der Entriegelung weist der Bolzen 22 eine nach aussen gerichtete Einkerbung 33 auf, welche zur Aufnahme einer Kugelschreiberspitze 17 ausgebildet ist.To carry out the unlocking, the pin 22 has an outwardly directed notch 33, which is designed to receive a ballpoint pen tip 17.

Bei dieser Ausführungsform der Erfindung sind die Federsysteme 2 und 3 wie im Ausführungsbeispiel nach den Figuren 1 und 2 ausgebildet, so dass sich ihre Beschreibung hier erübrigt.In this embodiment of the invention, the spring systems 2 and 3 are designed as in the exemplary embodiment according to FIGS. 1 and 2, so that their description is unnecessary here.

Zur Entriegelung wird mit einer Kugelschreiberspitze ein Druck auf die Einkerbung 33 ausgeübt, wie anhand der Figur 3 ersichtlich ist. Hierdurch drücktder Bolzen 22 exzentrisch auf die Schwinge 5 und bewirktso ein Drehmoment der Schwinge 5 gegen die Wirkung der Torsionsfeder 6, so dass die sich beklemmenden Flächen, nämlich die Aussenfläche der Stufe 32 und die Innenfläche der Nase 16 voneinander frei kommen. Dieser Zustand ist aus der Figur 4 zu entnehmen. In diesem Zustand kann die Spiralfeder 9 sich entspannen, wodurch die Öffnung des Bodens 27 ausgelöst wird. Ähnlich wie anhand der Figuren 1 und 2 beschrieben wurde, kann nun der Boden 27 aus seiner Entriegelung mit dem Nocken 18 in der Bohrung 20 entnommen werden, wodurch der Boden 27 vollständig von der Feuerzeughülse 26 frei ist.For unlocking, pressure is exerted on the notch 33 with a ballpoint pen tip, as can be seen from FIG. 3. As a result, the pin 22 presses eccentrically on the rocker 5 and thus causes a torque of the rocker 5 against the action of the torsion spring 6, so that the jammed surfaces, namely the outer surface of the step 32 and the inner surface of the nose 16 come free from each other. This state can be seen in FIG. 4. In this state, the spiral spring 9 can relax, which triggers the opening of the bottom 27. Similar to that described with reference to FIGS. 1 and 2, the base 27 can now be removed from its unlocking with the cam 18 in the bore 20, as a result of which the base 27 is completely free of the lighter sleeve 26.

Bei der Verwendung eines breiten Bodens 27 kann es vorteilhaft sein zwei Federsysteme 3 zu verwenden, welche parallel zur Achse 7 des Federsystems 2 liegen und gemeinsam und gleichzeitig wirken. Diese Massnahme kann für beide Ausführungsformen der Erfindung von Vorteil sein.When using a wide base 27, it can be advantageous to use two spring systems 3, which are parallel to the axis 7 of the spring system 2 and act together and simultaneously. This measure can be advantageous for both embodiments of the invention.

Für den Bolzen 22 ist es nicht erforderlich eine Spiralfeder als Druckelement vorzusehen, da dieser lediglich als Druckübertragungselement wirksam ist. Da dieser Bolzen 22 notwendigerweise mit einem Spiel versehen ist, ist es vorteilhaft ihn in Silikonfett zu lagern.For the bolt 22, it is not necessary to provide a spiral spring as a pressure element, since this is only effective as a pressure transmission element. Since this pin 22 is necessarily provided with play, it is advantageous to store it in silicone grease.

Mit der vorliegenden Erfindung wird ein abnehmbarer Boden eines Feuerzeugs vorgeschlagen, der sich ohne besondere Werkzeuge leicht lösen und verriegeln lässt, und welcher sich nicht in unbeabsichtigter Weise löst. Die Federsysteme wirken gegeneinander und stellen somit eine zuverlässige und dauerhaft wirkende Sicherung dar.With the present invention, a removable bottom of a lighter is proposed which can be easily released and locked without special tools and which does not inadvertently release. The spring systems work against each other and thus represent a reliable and long-lasting safeguard.
