Description

Die vorliegende Erfindung betrifft eine Taschenlampe mit einem Gehäuse, einer Lichtquelle, einer in einem Lampenkopf angeordneten Vorsatzoptik, wobei der Lampenkopf gegenüber der Lichtquelle längsaxial verschiebbar ist und einem zwischen dem Lampenkopf und dem Gehäuse angeordneten zweiteiligen Verbindungselement, dessen Teile gegeneinander längsaxial verschiebbar und verliersicher befestigt sind, wobei ein Teil des Verbindungselementes mit dem Lampenkopf und das andere Teil mit dem Gehäuse verbunden ist, die Teile zylinderförmig ausgebildet sind und jeweils einen Gewindeabschnitt besitzen und der Lampenkopf und das Gehäuse korrespondierende Gewindeabschnitte aufweisen.The present invention relates to a flashlight with a housing, a light source, arranged in a lamp head intent optics, wherein the lamp head relative to the light source is longitudinally displaceable axially and arranged between the lamp head and the housing two-piece connecting element whose parts are mounted against each other längsaxial displaced and captive wherein a part of the connecting element is connected to the lamp head and the other part is connected to the housing, the parts are cylindrical and each have a threaded portion and the lamp head and the housing have corresponding threaded portions.

Fokussierbare Taschenlampen der eingangs genannten Art sind prinzipiell nach dem Stand der Technik bekannt, wobei insbesondere in US 5,595,435 eine fokussierbare Taschenlampe mit einer entsprechenden Ausgestaltung offenbart wird.Focusable flashlights of the type mentioned are known in principle according to the prior art, in particular in US 5,595,435 a focusable flashlight with a corresponding configuration is disclosed.

Ferner wird in der DE 203 08 739 U1 eine Taschenlampe mit einer an der Stirnseite angeordneten Sammellinse, einer Lichtquelle und einem zwischen der Sammellinse und der Lichtquelle angeordneten, teilweise lichttransparenten Bildträger beschrieben. Um eine Projizierung des Bildes zu ermöglichen, ist der Bildträger in einer längsaxial beweglichen Schiebehülse angeordnet, mit derer längsaxialen Verschiebung sowohl der Abstand der Lichtquelle zur Sammellinse als auch der Abstand des Bildträgers zur Sammellinse veränderbar ist. Zur verschiebbaren Lagerung des Bildträgers sind neben dem Lampenkopf und dem Gehäuse mindestens drei weitere Verbindungselemente vorgesehen, nämlich ein Adapter, eine Führungshülse und eine Schiebehülse, so dass insbesondere die Montage der Taschenlampe relativ aufwendig ist.Furthermore, in the DE 203 08 739 U1 a flashlight with a arranged on the front side of the converging lens, a light source and arranged between the converging lens and the light source, partially transparent image carrier described. In order to enable a projection of the image, the image carrier is arranged in a longitudinally axially movable sliding sleeve, with which longitudinal axial displacement of both the distance of the light source to the converging lens and the distance of the image carrier to the converging lens is variable. For displaceable mounting of the image carrier at least three further connecting elements are provided in addition to the lamp head and the housing, namely an adapter, a guide sleeve and a sliding sleeve, so that in particular the assembly of the flashlight is relatively expensive.

Darüber hinaus sind Taschenlampen bekannt, bei denen zur Fokussierung des emittierten Lichts der Lampenkopf mit einem hierin gelagerten Reflektor und das Gehäuse mit der Lichtquelle über eine Gewindeverbindung so miteinander verbunden sind, dass der Reflektor und die Lichtquelle durch eine Drehbewegung relativ zueinander verschoben werden können. Diese Ausführungsform hat jedoch den Nachteil, dass zur Fokussierung stets zwei Hände benötigt werden, wobei mit einer Hand das Gehäuse festgehalten und mit der anderen Hand der Lampenkopf gedreht wird oder umgekehrt.In addition, flashlights are known in which for focusing the emitted light of the lamp head with a reflector mounted therein and the housing with the light source via a threaded connection are interconnected so that the reflector and the light source by a rotational movement relative to each other can be moved. However, this embodiment has the disadvantage that for focusing always two hands are needed, with one hand holding the case and rotated with the other hand, the lamp head or vice versa.

Schließlich wird in US 5,440,462 eine Lampe mit einem verschiebbaren Linsenhalter beschrieben, der über ein Schraubgewinde mit dem Gehäuse verbunden ist und hierüber verschoben werden kann.Finally, in US 5,440,462 a lamp with a sliding lens holder described which is connected via a screw thread with the housing and can be moved over it.

Es ist daher die Aufgabe der vorliegenden Erfindung eine fokussierbare Taschenlampe zu schaffen, die mit einer Hand fokussiert werden kann und für deren Montage nur eine geringe Anzahl von Verbindungselementen benötigt wird.It is therefore an object of the present invention to provide a focusable flashlight that can be focused with one hand and for their assembly only a small number of fasteners is needed.

Diese Aufgabe wird durch die Taschenlampe nach Anspruch 1 gelöst. Erfindungsgemäß besitzt ein Teil längsaxial abstehende Gleitschienen, die in Anlage mit auf dem anderen Teil ausgebildeten Gleitflächen sind, die das Gewinde des anderen Teils zumindest bereichsweise unterbrechen, wobei zur verliersicheren Verbindung die Gleitflächen einen Anschlag und die Gleitschienen verbreiterte Kopfteile aufweisen. Hierdurch wird eine besonders kompakte Bauweise einer fokussierbaren Taschenlampe geschaffen, die einfach herzustellen und zu bedienen ist. Aufgrund der geringen Anzahl von verwendeten Bauteilen reduzieren sich zudem die Montagekosten. Ferner löst sich durch die verliersichere Verbindung der Teile der Lampenkopf beim Fokussieren nicht ungewollt von dem Gehäuse und die relative Bewegung der Teile zueinander wird einerseits durch die Stirnseiten der Teile selbst und andererseits durch den Anschlag und das verbreitete Kopfteil begrenzt.This object is achieved by the flashlight according to claim 1. According to the invention has a part longitudinally projecting slide rails, which are in contact with formed on the other part sliding surfaces, which interrupt the thread of the other part at least partially, for captive connection, the sliding surfaces have a stop and the slide rails widened head parts. As a result, a particularly compact design of a focusable flashlight is created, which is easy to manufacture and operate. Due to the small number of components used, the assembly costs are also reduced. Furthermore, by captive connection of the parts of the lamp head when focusing not unintentionally detached from the housing and the relative movement of the parts to each other is limited on the one hand by the end faces of the parts themselves and on the other hand by the stop and the common head.

Weitere bevorzugte Ausführungsformen der vorliegenden Erfindung werden im folgenden sowie in den Unteransprüchen beschrieben.Further preferred embodiments of the present invention are described below and in the subclaims.

Nach einer ersten Ausführungsform ist vorgesehen, dass die Teile zylinderförmig ausgebildet sind und jeweils einen Gewindeabschnitt besitzen, wobei der Lampenkopf und das Gehäuse korrespondierende Gewindeabschnitte aufweisen. Alternativ hierzu können die Teile auch über eine Bajonettverbindung oder eine andere lösbare Verbindung, wie beispielsweise eine Rastverbindung, mit dem Gehäuse bzw. dem Lampenkopf verbunden sein. Eine Gewindeverbindung ist allerdings aufgrund der einfachen Herstellbarkeit und Montierbarkeit bevorzugt.According to a first embodiment, it is provided that the parts are cylindrical and each have a threaded portion, wherein the lamp head and the housing have corresponding threaded portions. alternative For this purpose, the parts can also be connected via a bayonet connection or another releasable connection, such as a latching connection, with the housing or the lamp head. However, a threaded connection is preferred because of the ease of manufacture and assembly.

Vorzugsweise sind die Gleitschienen teilzylinderförmig ausgebildet. Bei einer Ausführungsform mit teilzylinderförmigen Gleitschienen sind diese vorzugsweise äquiangular beabstandet. Je nach Größe der Taschenlampe kann die Anzahl von Gleitschienen variieren, wobei drei Gleitschienen und entsprechend drei Gleitflächen bevorzugt sind.Preferably, the slide rails are partially cylindrical. In an embodiment with part-cylindrical slide rails, these are preferably equiangularly spaced. Depending on the size of the flashlight, the number of slides may vary, with three slides and correspondingly three sliding surfaces are preferred.

Bei einer Ausführungsform mit mehreren Gleitschienen können die Erweiterungen in tangentialer Richtung angeordnet sein.In an embodiment with a plurality of slide rails, the extensions may be arranged in the tangential direction.

Vorzugsweise ist vorgesehen, dass die Gleitflächen auf der Außenseite des Teils angeordnet sind und dass das Gewinde von den Gleitflächen zumindest bereichsweise unterbrochen ist.It is preferably provided that the sliding surfaces are arranged on the outside of the part and that the thread of the sliding surfaces is at least partially interrupted.

Um zu verhindern, dass der Lampenkopf ungewollt gegenüber dem Gehäuse und damit der Lichtquelle verschoben wird, ist vorzugsweise ein Führungselement angeordnet, so dass eine Relativbewegung der Teile nur gegen eine Kraft ausgeführt werden kann. Im einfachsten Fall ist das Führungselemente eine O-Ring aus Gummi oder einem anderen elastischen Material, der einerseits das Gehäuse umfasst und andererseits so dimensioniert ist, dass zwischen dem Lampenkopf und dem O-Ring eine so große Reibung entsteht, dass der Lampenkopf nur gewollt verschoben werden kann. Ein derartiges Führungselement ist günstig herstellbar und im Verschleißfall einfach austauschbar. Zudem dient das Führungselement als Dichtung, so dass kein Schmutz in Form von Staub in den Lampenkopf eindringen kann.In order to prevent that the lamp head is moved unintentionally relative to the housing and thus the light source, a guide element is preferably arranged so that a relative movement of the parts can be performed only against a force. In the simplest case, the guide elements is an O-ring made of rubber or other elastic material, which on the one hand comprises the housing and on the other hand dimensioned so that between the lamp head and the O-ring such a friction arises that the lamp head moved only deliberately can be. Such a guide element is inexpensive to produce and easy to replace in case of wear. In addition, the guide element serves as a seal, so that no dirt in the form of dust can penetrate into the lamp head.

Das Verbindungselement ist vorzugsweise ein Kunststoffspritzgießteil oder aus Metall, insbesondere Aluminium, gefertigt.The connecting element is preferably a plastic injection-molded part or made of metal, in particular aluminum.

Nach einer weiteren Ausgestaltung der vorliegenden Erfindung ist vorgesehen, dass die Lichtquelle eine LED ist, die auf einem plattenförmigen Halter angeordnet ist.According to a further embodiment of the present invention it is provided that the light source is an LED which is arranged on a plate-shaped holder.

Dieser Halter weist vorzugsweise rückseitig kreis- und/oder ringförmig konzentrisch angeordnete elektrische Kontaktflächen auf, die mit entsprechenden elektrischen Kontakten der Batterien oder der Akkumulatoren verbunden sind. Ferner besitzt der Halter rückseitig eine ringförmige Anlagefläche, die aus einem wärmeleitenden Material besteht und mit dem Gehäuse in Anlage ist. Hierdurch wird die in der Lichtquelle entstehende Wärme an das Gehäuse abgeführt, was insbesondre die Haltbarkeit der Lichtquelle erhöht. Als Materialien eignen sich insbesondere Aluminium, Messing oder Kupfer.This holder preferably has on the back circular and / or annular concentrically arranged electrical contact surfaces which are connected to corresponding electrical contacts of the batteries or accumulators. Furthermore, the holder has on the back an annular contact surface, which consists of a thermally conductive material and is in contact with the housing. As a result, the heat generated in the light source is dissipated to the housing, which increases insbesondre the durability of the light source. As materials are particularly suitable aluminum, brass or copper.
