Description
Die vorliegende Erfindung betrifft eine Taschenlampe mit einem Gehäuse, einer Lichtquelle, einem Lampenkopf mit einer Vorsatzoptik, der zur Fokussierung des abgestrahlten Lichtkegels relativ zur Lichtquelle längsaxial verschiebbar ist und einer Klemmvorrichtung zur Fixierung des Lampenkopfes in einer wählbaren längsaxialen Position.The present invention relates to a flashlight with a housing, a light source, a lamp head with an attachment optics, which is longitudinally axially displaceable for focusing the emitted light cone relative to the light source and a clamping device for fixing the lamp head in a selectable longitudinal axial position.
Taschenlampen sind nach dem Stand der Technik bereits bekannt. Beispielsweise wird in
Nachteilig an einer solchen Taschenlampe ist jedoch, dass die Einstellung der relativen Position zwischen Lampenkopf bzw. Reflektor und Lichtquelle möglichst leichtgängig sein soll, was allerdings zur Folge hat, dass die relative Position zwischen Lampenkopf bzw. Reflektor und Lichtquelle schon bereits bei leichten Erschütterungen ungewollt verschoben werden kann, womit sich die eingestellte Fokussierung verstellt. Insbesondere bei Fahrradlampen, die im Gebrauch einer permanenten Erschütterung unterliegen, ist dieses Problem häufig zu beobachten.A disadvantage of such a flashlight, however, is that the setting of the relative position between the lamp head or reflector and light source should be as smooth as possible, but this has the consequence that the relative position between the lamp head or reflector and light source already moved unintentionally even with slight shocks can be, which adjusts the set focus. In particular, in bicycle lamps, which are subject to a permanent vibration in use, this problem is frequently observed.
Eine Taschenlampe, die fokussierbar ist und deren Larnpenkopf mittels einer Klemmvorrichtung in einer wählbaren längsaxialen Position fixierbar ist, geht aus
Es ist daher die Aufgabe der vorliegenden Erfindung eine Taschenlampe zu schaffen, die einerseits eine leichtgängige Verschiebung des Reflektors relativ zu der Lichtquelle ermöglicht und andererseits ein ungewolltes Verstellen der eingestellten Fokussierung verhindert.It is therefore an object of the present invention to provide a flashlight, on the one hand enables a smooth displacement of the reflector relative to the light source and on the other hand prevents unintentional adjustment of the adjusted focus.
Diese Aufgabe wird durch die Taschenlampe nach Anspruch 1 gelöst. Erfindungsgemäß besitzt die Klemmvorrichtung einen um die Längsachse der Taschenlampe drehbaren Klemmkörper mit mindestens einem endseitig angeordneten, in radialer Richtung schwenk- oder spreizbaren Klemmelement.This object is achieved by the flashlight according to
Hierdurch wird vorteilhafter Weise die Möglichkeit geschaffen, eine leichtgängige und präzise einstellbare Fokussiermechanik mit einer Fixierungsmöglichkeit des Lampenkopfes zu verbinden, so dass die eingestellte Fokusstellung nicht verstellt werden kann.As a result, the possibility is advantageously created to connect a smooth and precisely adjustable focusing mechanism with a fixation possibility of the lamp head, so that the set focus position can not be adjusted.
Bevorzugte Ausgestaltungen der vorliegenden Erfindung werden im Folgenden sowie in den Unteransprüchen beschrieben.Preferred embodiments of the present invention are described below and in the subclaims.
Nach einer ersten bevorzugten Ausführungsform ist eine reib- oder formschlüssige Fixierung des Lampenkopfes vorgesehen, wobei die Klemmvorrichtung vorzugsweise über eine Drehbewegung des Lampenkopfes relativ zu dem Gehäuse bedienbar ist. Somit kann die Fokusstellung einfach und präzise durch längsaxiales Verschieben des Lampenkopfes eingestellt werden, wobei die Position über eine Drehbewegung des Lampenkopfes fixiert werden kann. Beide Einstellungen können einhändig durchgeführt werden, was die Bedienbarkeit der Taschenlampe zudem erhöht. Alternativ hierzu sind auch Konstruktionen denkbar, bei denen die längsaxiale Verschiebung des Reflektors relativ zu der Lichtquelle durch eine Drehbewegung und die Fixierung durch eine längsaxiale Verschiebung des Lampenkopfes bewirkt wird. Hierzu eignet sich beispielsweise die Verwendung eines Spreizkonus.According to a first preferred embodiment, a frictional or positive fixing of the lamp head is provided, wherein the clamping device is preferably operable via a rotational movement of the lamp head relative to the housing. Thus, the focus position can be easily and precisely adjusted by longitudinal axial displacement of the lamp head, wherein the position can be fixed by a rotational movement of the lamp head. Both settings can be performed with one hand, which also increases the usability of the flashlight. Alternatively, constructions are conceivable in which the longitudinal axial displacement of the reflector is effected relative to the light source by a rotational movement and the fixation by a longitudinal axial displacement of the lamp head. For this purpose, for example, the use of an expansion cone is suitable.
Nach einer weiteren bevorzugten Ausführungsform der vorliegenden Erfindung gleitet das Klemmelement bei einer Drehung des Klemmkörpers auf einer Auflauffläche, die so angeordnet ist, dass das Klemmelement mit zunehmender Drehung des Klemmkörpers in radialer Richtung zunehmend verschwenkt oder gespreizt wird. Hierzu kann die Auflauffläche einerseits parallel zur Umfangslinie der Taschenlampe angeordnet und das Klemmelement verjüngend ausgebildet sein, oder die Auflauffläche ist winklig zur Umfangslinie der Taschenlampe ausgerichtet und das Klemmelement besitzt eine konstante Dicke. Selbstverständlich sind Kombinationen hiervon soweit mit abgedeckt, solange gewährleistet ist, dass die Klemmelemente mit zunehmender Drehung des Klemmkörpers in radialer Richtung hinreichend verschwenkt oder gespreizt werden, so dass sie deren Klemmfunktion erfüllen.According to a further preferred embodiment of the present invention, the clamping element slides on a rotation of the clamping body on a Bearing surface which is arranged so that the clamping element is increasingly pivoted or spread with increasing rotation of the clamping body in the radial direction. For this purpose, the ramp surface on the one hand arranged parallel to the peripheral line of the flashlight and the clamping element may be tapered, or the ramp surface is aligned at an angle to the peripheral line of the flashlight and the clamping element has a constant thickness. Of course, combinations thereof are so far covered as long as it is ensured that the clamping elements are swiveled or spread sufficiently with increasing rotation of the clamping body in the radial direction, so that they fulfill their clamping function.
Im zusammengebauten Zustand der Taschenlampe umgreift der Lampenkopf die Klemmvorrichtung, so dass zwischen der Klemmvorrichtung und dem Lampenkopf ein Ringspalt entsteht. Solange das Klemmelement nicht in radialer Richtung verschwenkt oder gespreizt wird, ist der Lampenkopf längsaxial beweglich, so dass die gewünschte Fokusstellung eingestellt werden kann. Über eine Drehbewegung des Lampenkopfes wird das Klemmelement jedoch vorzugsweise derart radial verschwenkt, dass es auf die Innenmantelfläche des Lampenkopfes drückt, so dass der Lampenkopf reibschlüssig fixiert ist.In the assembled state of the flashlight, the lamp head surrounds the clamping device, so that an annular gap arises between the clamping device and the lamp head. As long as the clamping element is not pivoted or spread in the radial direction, the lamp head is longitudinally movable, so that the desired focus position can be adjusted. By way of a rotary movement of the lamp head, however, the clamping element is preferably pivoted radially in such a way that it presses against the inner lateral surface of the lamp head, so that the lamp head is fixed in a frictionally engaged manner.
Um den Klemmkörper und mithin die Klemmelemente drehen zu können, ist nach einer bevorzugten Ausführungsform der vorliegenden Erfindung vorgesehen, dass der Klemmkörper einen Mitnehmer aufweist, der in eine Nut des Lampenkopfes eingreift, so dass der Klemmkörper durch eine Drehung des Lampenkopfes drehbar ist.In order to rotate the clamping body and thus the clamping elements, according to a preferred embodiment of the present invention, it is provided that the clamping body has a driver, which engages in a groove of the lamp head, so that the clamping body is rotatable by rotation of the lamp head.
Damit die Klemmvorrichtung auch bei starken Erschütterungen die eingestellte Stellung beibehält, ist vorzugsweise die Klemmvorrichtung im Klemmzustand in eine Raststellung überführbar, wozu der Klemmkörper, insbesondere das Klemmelement, und/oder die Auflagefläche, eine Nut und/oder eine entsprechende Rastnase besitzen. Mit anderen Worten, die Klemmvorrichtung rastet bei einem bestimmten überstrichenen Drehwinkel in eine Raststellung ein, so dass der Lampenkopf sich nicht ungewollt in die nicht fixierte Stellung zurückgedreht.Thus, the clamping device maintains the set position even with strong shocks, preferably the clamping device in the clamping state in a detent position can be transferred, including the clamping body, in particular the clamping element, and / or the support surface, a groove and / or a corresponding locking lug. In other words, the clamping device engages at a certain swept angle of rotation in a locked position, so that the lamp head is not unintentionally turned back into the unfixed position.
Die vorliegende Erfindung ist nicht auf Klemmkörper beschränkt, die ein einziges Klemmelement besitzen, sondern es sind auch Klemrrikörper vorgesehen, die mehrere, vorzugsweise zwei, Klemmelemente aufweisen. Die Klemmkörper und insbesondere die Klemmelemente sind als Kunststoffspritzgießteile ausgebildet.The present invention is not limited to clamping bodies having a single clamping element, but Klemrrikörper are also provided which have a plurality, preferably two, clamping elements. The clamping body and in particular the clamping elements are formed as plastic injection molded parts.

Nach einer konkreten Ausführungsform der vorliegenden Erfindung besitzt die Klemmvorrichtung 1 einen Klemmkörper 2, der um die Längsachse A der Taschenlampe 3 drehbar gelagert ist. Dabei liegt der Klemmkörper 1 auf einem Sockel 5 auf, auf dem in zentraler Position eine Lichtquelle, vorzugsweise eine LED 21, angeordnet ist. Ferner sind auf dem Sockel 5 zwei nierenförmige Elemente 6, 6' angeordnet, die zweierlei Funktionen erfüllen. Einerseits sind die Außenflächen der nierenförmigen Elemente 6, 6' als Auflaufflächen 7, 7' ausgebildet. Andererseits dienen die nierenförmigen Elemente 6, 6' als Abstandhalter für eine Abdeckplatte 8 (siehe
Der Klemmkörper 2 besteht im Wesentlichen aus einem entlang des Durchmessers der Taschenlampe 3 angeordneten Steg 9, wobei zur Durchführung der LED 21 eine zentrale Ausnehmung 10 vorgesehen ist. An dem Steg 9 sind in radialer Richtung zwei Klemmelemente 11, 11' schwenkbar angeordnet, die in Anlage mit den Auflaufflächen 7, 7' sind. Darüber hinaus besitzt der Klemmkörper 2 einen radial abstehenden Mitnehmer 12, der im zusammengebauten Zustand in eine Nut 13 des Lampenkopfes 14 eingereift. Im dargestellten Ausführungsbeispiel entsteht zwischen dem Lampenkopf 14 und dem Gehäuse 16 bzw. dem Sockel 5 ein Ringspalt 17, so dass der Lampenkopf 14 in längsaxialer Richtung (Pfeil 4) verschoben werden kann.The
Sofern der Lampenkopf 14 jedoch im Uhrzeigersinn (Pfeil 18) gedreht wird, pressen sich die Klemmelemente 11, 11' gegen die Zylinderinnenmantelfläche des Lampenkopfes 14, da die Klemmelemente 11, 11' eine zunehmend größere Dicke 15, 15' besitzen, so dass sie von den nierenförmigen Elementen 6, 6' nach außen gedrückt werden und den Ringspalt 17 bereichsweise schließen. Die Kraft, mit der die Klemmelemente 11, 11' auf die Innenmantelfläche des Lampenkopfes 14 drücken, ist groß genug, um diesen reibschlüssig zu fixieren. Damit die Klemmvorrichtung 1 nicht in die in
