Description
Die vorliegende Erfindung betrifft eine Taschenlampe mit einem zylinderförmigen Batteriegehäuse an dessen einem Ende eine stromleitende Kontaktfläche ausgebildet ist, einer Endkappe sowie einer Kontaktfeder mit Kontaktpunkten, die einen Pol einer im Batteriegehäuse gelagerten Batterie mit der Kontaktfläche des Batteriegehäuses verbindet.The present invention relates to a flashlight with a cylindrical battery housing at one end of a current-conducting contact surface is formed, an end cap and a contact spring with contact points, which connects a pole of a battery housing mounted in the battery housing with the contact surface of the battery case.
Eine derartige Taschenlampe ist beispielsweise in der
Bereits in dieser Druckschrift wird erwähnt, dass sich eine Vielzahl von Kontaktstellen in einem Stromkreis einer Taschenlampe ungünstig auf die Bedienbarkeit auswirken, da an Kontaktstellen die elektrischen Kontakte durch Oxidation, Verschmutzung und Verschleißerscheinungen keinen optimalen elektrischen Kontakt bilden, so dass nach Lösungen gesucht wird, die Anzahl der Kontaktstellen zu verringern. Die in der
Es ist daher Aufgabe der vorliegenden Erfindung eine Taschenlampe mit einer Endkappe zu schaffen, die bei einer möglichst geringen Anzahl von erforderlichen Kontaktstellen einfach herzustellen ist, womit einerseits Produktionskosten reduziert werden und andererseits ein stabilerer elektrischer Kontakt geschaffen wird.It is therefore an object of the present invention to provide a flashlight with an end cap, which is easy to manufacture with the lowest possible number of contact points, which on the one hand production costs are reduced and on the other hand a more stable electrical contact is created.
Dieser Aufgabe wird durch die Taschenlampe nach Anspruch 1 gelöst, wonach erfindungsgemäß die Kontaktpunkte an gegenüberliegenden Enden der Kontaktfeder angeordnet sind. Mit anderen Worten, es wird eine Taschenlampe vorgeschlagen, die in ihrer Endkappe eine Kontaktfeder besitzt, wobei diese an zwei gegenüberliegenden Enden Kontaktpunkte aufweist, die einerseits mit dem Pol einer Batterie und andererseits mit den Kontaktflächen des Batteriegehäuses verbunden werden können. Vorzugsweise ist hierbei die Kontaktfeder als Schraubenfeder oder als Blattfeder ausgebildet, wobei auch andere Kontaktfedern vorstellbar sind.This object is achieved by the flashlight according to claim 1, which according to the invention, the contact points are arranged at opposite ends of the contact spring. In other words, it is proposed a flashlight, which has a contact spring in its end cap, which has contact points at two opposite ends, which can be connected on the one hand to the pole of a battery and on the other hand to the contact surfaces of the battery case. Preferably, in this case, the contact spring is designed as a helical spring or as a leaf spring, wherein other contact springs are conceivable.
Prinzipiell sind drei verschiedene Ausgestaltungen der vorliegenden Erfindung vorgesehen, die im Folgenden sowie in den Unteransprüchen erläutert werden.In principle, three different embodiments of the present invention are provided, which are explained below and in the dependent claims.
Nach einer ersten bevorzugten Ausgestaltung ist vorgesehen, dass die Endkappe ein Außengewinde und das Batteriegehäuse ein korrespondierendes Innengewinde besitzt und dass die Kontaktfeder endseitig mindestens ein radiales Teilstück besitzt, das in eine Ausnehmung der Endkappe derart eingreift, dass das Teilstück im zusammengebauten Zustand mit der Kontaktfläche des Batteriegehäuses verbunden ist. Hierzu muss das Teilstück aus der Ausnehmung um ein bestimmtes Maß herausragen, so dass das herausragende Teilstück auf die Kontaktflächen des Batteriegehäuses gedrückt werden kann. Prinzipiell kann die Kontaktfläche ring- oder teilringförmig an der Stirnseite des Batteriegehäuses angeordnet sein. Alternativ hierzu kann die Kontaktfläche auch als ring- oder teilringförmiger Sockel innerhalb des Batteriegehäuses ausgebildet sein. Vorzugsweise ist die Ausnehmung zwischen dem Gewinde der Endkappe und einem Abschlussstück angeordnet. An dieser Stelle kann die Ausnehmung besonders einfach durch eine Bohrung in die Endkappe eingebracht werden.According to a first preferred embodiment, it is provided that the end cap has an external thread and the battery housing has a corresponding internal thread and that the contact spring end has at least one radial portion which engages in a recess of the end cap such that the portion in the assembled state with the contact surface of the Battery housing is connected. For this purpose, the portion of the recess must protrude by a certain amount, so that the protruding portion can be pressed onto the contact surfaces of the battery case. In principle, the contact surface may be arranged annularly or partially annularly on the end face of the battery housing. Alternatively, the contact surface may be formed as a ring or semi-annular base within the battery case. Preferably, the recess is disposed between the threads of the end cap and a termination piece. At this point, the recess can be particularly easily introduced through a hole in the end cap.
Nach einer alternativen Ausgestaltung der vorliegenden Erfindung ist vorgesehen, dass die Endkappe ein Innengewinde und das Batteriegehäuse ein korrespondierendes Außengewinde besitzt und dass die Kontaktfeder endseitig zumindest in einem Teilbereich einen so großen Radius aufweist, dass dieser Teilbereich im eingebauten Zustand mit der Kontaktfläche des Batteriegehäuses verbunden ist. Vorzugsweise ist hierzu die Kontaktfeder eine Schraubenfeder, die bevorzugt kegelstumpfförmig ausgebildet ist. Dabei weist die kegelstumpfförmige Schraubenfeder vorzugsweise endseitig einen Teilbereich auf mit einem so großen Radius auf, dass dieser Teilbereich im eingebauten Zustand mit der Kontaktfläche des Batteriegehäuses verbunden ist. Anders ausgedrückt, das spitze Ende der Kontaktfeder ist mit der Batterie und das erweiterte Ende mit der Endkappe bzw. der Kontaktfläche verbunden, so dass ein kreisförmiger Linienkontakt gebildet wird. Diese Ausführungsform ist besonders gut als Schalter auszugestalten, da der Kontaktschluss aufgrund eines Linienkontaktes zwischen Kontaktfeder und Batteriegehäuse durch Drehen der Endkappe hergestellt werden kann. Ferner ist vorgesehen, dass die Endkappe so weit auf das Batteriegehäuse aufgeschraubt werden kann, dass der Kontakt gerade so noch nicht geschlossen ist, so dass ein Kontakt unter Ausnutzung des Gewindespiels geschlossen werden kann, womit diese Ausführungsform auch als Tastschalter ausgebildet sein kann.According to an alternative embodiment of the present invention, it is provided that the end cap has an internal thread and the battery housing has a corresponding external thread and that the contact spring has at least in a partial region such a large radius that this portion is connected in the installed state with the contact surface of the battery case , For this purpose, the contact spring is preferably a helical spring, which is preferably frusto-conical. In this case, the frustoconical helical spring preferably has a partial region on the end with such a large radius that this partial region is connected in the installed state to the contact surface of the battery housing. In other words, the tip end of the contact spring is connected to the battery and the extended end to the end cap or the contact surface, so that a circular line contact is formed. This embodiment is particularly well designed as a switch, since the contact closure due to a line contact between the contact spring and battery case can be made by turning the end cap. It is further provided that the end cap can be screwed onto the battery case so far that the contact is just not closed so that a contact can be closed by utilizing the thread play, so this embodiment can also be designed as a push button.
Nach einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung ist vorgesehen, dass die Kontaktfeder ein radiales Teilstück aufweist, das ein- oder zweistückig mit einem Clip verbunden ist, wobei der Kontakt durch Drehen der Endkappe hergestellt wird. Ferner ist nach einer weiteren Ausgestaltung vorgesehen, dass zwischen dem Teilbereich und der Kontaktfläche im eingebauten Zustand eine Lücke besteht, so dass der Kontakt durch eine Schwenkbewegung des Clips geschlossen wird. Bei beiden Ausgestaltungen ergeben sich hinsichtlich der Ausbildung als Schalter die oben genannten Vorteile, da auch hier die Endkappe soweit gedreht werden kann, dass der Kontaktschluss entweder über eine Drehbewegung der Endkappe oder durch Drücken unter Ausnutzung des Gewindespiels hergestellt werden kann.According to another preferred embodiment of the present invention it is provided that the contact spring has a radial portion which is connected in one or two pieces with a clip, wherein the contact is made by rotating the end cap. Furthermore, according to a further embodiment, there is a gap between the partial area and the contact area in the installed state, so that the contact is closed by a pivoting movement of the clip. In both embodiments, the above-mentioned advantages arise in terms of training as a switch, since here too, the end cap can be rotated so far that the contact closure can be made either by a rotational movement of the end cap or by pressing the thread play using.
Vorzugsweise ist der Clip längsaxial am Batteriegehäuse angeordnet. Diese Taschenlampe lässt sich durch Drehen der Endkappe derart einstellen, dass die Taschenlampe durch ein leichtes Drücken bzw. Verschwenken des Clips ein Kontakt geschlossen wird und der Kontakt durch entgegengesetztes Ziehen wieder unterbrochen wird. Hiermit ist es sogar möglich, die Taschenlampe so einzustellen, dass der Kontakt unterbrochen ist, wenn die Taschenlampe an dem Clip in einer Tasche hängt, wie beispielsweise einer Brusttasche, und der Stromkreis geschlossen wird, sobald die Taschenlampe der Tasche entnommen wird.Preferably, the clip is arranged longitudinally axially on the battery housing. This flashlight can be adjusted by turning the end cap so that the flashlight is closed by a slight pressing or pivoting of the clip a contact and the contact is interrupted by opposing pulling again. This even makes it possible to adjust the flashlight so that the contact is broken when the flashlight hangs on the clip in a pocket, such as a breast pocket, and the circuit is closed as soon as the flashlight is removed from the pocket.
