Description

Taschenlampe mit einem Endkappenschalter  Flashlight with an end cap switch
Die vorliegende Erfindung betrifft eine Taschenlampe mit einem Taschenlampengehäuse und einem in einer Endkappe angeordneten Tast-, Rast- oder Drehschalter, der ein Schaltergehäuse besitzt, in das ein erstes und ein zweites Kontaktelement eingreifen. The present invention relates to a flashlight with a flashlight housing and arranged in an end cap tactile, detent or rotary switch, which has a switch housing, in which a first and a second contact element engage.
Es ist bekannt, einen Schalter in der Endkappe zu integriert, die auf das Taschenlampengehäuse aufgeschraubt wird, wobei die Batterie(n) bzw. die Akkumulatoren bei abgeschraubter Endkappe in das Taschenlampengehäuse eingeführt werden. Bei derartigen Taschenlampen ist das eine Kontaktelement des Schalters mit einer Spiralfeder verbunden, die einerseits die Batterien innerhalb der Taschenlampe fixiert und andererseits eine Verbindung mit einem Pol der Batterie bildet, so dass der Strom über die Spiralfeder fließt. Um im eingeschalteten Zustand einen geschlossenen Stromkreis zu schaffen, wird üblicherweise der andere Kontakt über die Endkappe geführt, so dass der elektrische Strom von dort aus weiter über das Gewinde oder andere Kontaktflächen über das Taschenlampengehäuse zur Lichtquelle fließt. It is known to integrate a switch in the end cap, which is screwed onto the flashlight housing, wherein the battery (s) or the accumulators are inserted with unscrewed end cap in the flashlight housing. In such flashlights, the one contact element of the switch is connected to a coil spring, which fixes the batteries on the one hand inside the flashlight and on the other hand forms a connection to one pole of the battery, so that the current flows through the coil spring. In order to create a closed circuit in the on state, usually the other contact is guided over the end cap, so that the electric current continues to flow from there via the thread or other contact surfaces via the flashlight housing to the light source.
Nachteilig an den Schaltungsanordnungen, wie sie in herkömmlichen Taschenlampen realisiert sind, ist zum einen, dass der Strom über eine Vielzahl von Kontaktflä- chen geführt wird, wobei über jeder Kontaktfläche ein entsprechender Kontaktwiderstand abfällt. Darüber hinaus wird durch den Stromfluss innerhalb der Spiralfeder eine Selbstinduktionsspannung induziert, die dem eigentlichen Stromfluss entgegenwirkt. Beides führt dazu, dass über der Lichtquelle eine geringere Spannung abfällt, womit die Leuchtintensität der Lichtquelle deutlich sinkt. A disadvantage of the circuit arrangements, as they are realized in conventional flashlights, is firstly that the current is passed over a multiplicity of contact areas, with a corresponding contact resistance dropping over each contact area. In addition, a self-induction voltage is induced by the current flow within the coil spring, which counteracts the actual current flow. Both result in a lower voltage dropping above the light source, whereby the luminous intensity of the light source drops markedly.
Es ist daher Aufgabe der vorliegenden Erfindung eine Taschenlampe mit einem Schalter zu schaffen, bei der die Anzahl der Kontakte reduziert und der Stromfluss optimiert wird, insbesondere ein Stromfluss über eine Spiralfeder vermieden wird. It is therefore an object of the present invention to provide a flashlight with a switch, in which the number of contacts is reduced and the current flow is optimized, in particular a flow of current through a coil spring is avoided.
Diese Aufgabe wird durch die Taschenlame nach Anspruch 1 gelöst, bei der erfindungsgemäß das erste Kontaktelement eine Blattfeder ist, die unmittelbar an dem elektrisch leitenden Taschenlampengehäuse oder unmittelbar an der elektrisch leitenden und mit dem Taschenlampengehäuse lösbar verbundenen Endkappe kontaktschließend anliegt, wobei das zweite Kontaktelement außerhalb des Schaltergehäuses als gebogene Blattfeder ausgebildet ist und unmittelbar mit einer Stromversorgung verbunden ist. Hierdurch wird eine Vielzahl von Kontaktflächen vermieden. Insbesondere wird ein Kontakt zwischen einem Kontaktelement und der Kontaktfeder eingespart. Darüber hinaus wird der Strom nicht mehr über die Spiralfeder geführt, so dass keine Leistung aufgrund der relativ hohen Eigeninduktivität einer Spiralfeder verloren geht. Vorteilhafterweise geht durch die erfindungsgemäße Schaltungsanordnung weniger Leistung verloren, so dass diese der Lichtquelle zur Verfügung steht. This object is achieved by the Taschenlame according to claim 1, wherein according to the invention, the first contact element is a leaf spring, which is directly on the electrically conductive flashlight housing or directly against the electrically conductive and detachably connected to the flashlight housing end cap is in contact-contact, wherein the second contact element is formed outside of the switch housing as a bent leaf spring and is directly connected to a power supply. As a result, a large number of contact surfaces is avoided. In particular, a contact between a contact element and the contact spring is saved. In addition, the current is no longer guided by the coil spring, so that no power is lost due to the relatively high self-inductance of a coil spring. Advantageously, less power is lost by the circuit arrangement according to the invention, so that it is available to the light source.
Weitere Ausgestaltungen der Erfindung werden im Folgenden sowie in den Unteransprüchen beschrieben. Further embodiments of the invention are described below and in the subclaims.
Insbesondere ist nach einer bevorzugten Ausführungsform vorgesehen, dass als Lichtquelle eine Leuchtdiode (LED) und als Stromversorgung mindestens eine Batterie oder ein Akkumulator, d.h. mindestens eine wiederaufladbare Batterie, vorgesehen ist. Gleichermaßen können auch - wie nach dem Stand der Technik bekannt - Batteriestapel aus mehreren in Serie geschalteten Batterien verwendet werden. Vor allem die Verwendung einer LED als Lichtquelle reduziert den Stromverbrauch, so dass zur Lichterzeugung mehr Energie zur Verfügung steht. In particular, according to a preferred embodiment, it is provided that the light source is a light-emitting diode (LED) and, as a power supply, at least one battery or accumulator, i. at least one rechargeable battery is provided. Likewise, as known in the art, battery packs may be used from a plurality of batteries connected in series. In particular, the use of an LED as a light source reduces power consumption, so that more energy is available to generate light.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Schalter in einem Führungsgehäuse angeordnet ist, das Ausnehmungen besitzt, durch die die Kontakte des Schalters radial oder stirnseitig nach außen ragen, wo sie als Blattfedern ausgebildet sind und stromleitende Kontaktflächen bilden. Das Führungsgehäuse ist vorzugsweise als Kunststoffspritzgießteil ausgebildet, womit die Produktionskosten äußerst gering gehalten werden können. Das Führungsgehäuse ist bevorzugt zweiteilig ausgestaltet und besteht vorzugsweise aus zwei halbzylinderschalenförmi- gen Teilsegmenten. Um einen Schalter in ein Führungsgehäuse einzuführen, werden zunächst die Teilsegmente voneinander getrennt und der Schalter wird in einer Aus- nehmung innerhalb eines Teilsegmentes gelegt. Anschließend werden die Teilsegmente wieder zu einem Führungsgehäuse zusammengefügt, womit der Schalter innerhalb des Führungsgehäuses gelagert und gehalten ist. Damit die Kontakte des Schalters aus dem Führungsgehäuse herausgeführt werden können, um einen elektrischen Kontakt zu ermöglichen, sind nach einer bevorzugten Ausführungsform der Erfindung an mindestens einer der Verbindungsflächen der Teilsegmente nut- förmige Ausnehmungen vorgesehen, in denen die Kontakte bei eingelegtem Schalter liegen. Bevorzugte Positionen der genannten Ausnehmungen werden später noch näher erläutert. According to a development of the invention it is provided that the switch is arranged in a guide housing having recesses through which the contacts of the switch project radially or frontally outwards, where they are formed as leaf springs and form electrically conductive contact surfaces. The guide housing is preferably designed as a plastic injection molded part, whereby the production costs can be kept extremely low. The guide housing is preferably designed in two parts and preferably consists of two halbzylinderschalenförmi- gene sub-segments. To insert a switch into a guide housing, first the sub-segments are separated from each other and the switch is in an output placed within a subsegment. Subsequently, the sub-segments are reassembled into a guide housing, whereby the switch is mounted and held within the guide housing. Thus, the contacts of the switch can be led out of the guide housing to allow electrical contact, groove-shaped recesses are provided in at least one of the connecting surfaces of the sub-segments according to a preferred embodiment of the invention, in which the contacts are when the switch is engaged. Preferred positions of said recesses will be explained later in more detail.
Das Führungsgehäuse besitzt vorzugsweise eine weitere Ausnehmung, durch die im zusammengebauten Zustand ein Betätigungsknopf greift, mit dem der Schalter betätigt wird. Der Betätigungsknopf ist dabei ein Bauteil der Endkappe, in der der Betätigungsknopf koaxial gelagert ist. Vorzugsweise ist zwischen dem Betätigungsknopf und dem Schalter eine flexible Gummidichtung angeordnet, womit der Schalter und die Kontakte staub- und feuchtigkeitsdicht gelagert sind. The guide housing preferably has a further recess through which engages in the assembled state, an operating knob with which the switch is actuated. The operating knob is a component of the end cap, in which the actuating button is mounted coaxially. Preferably, a flexible rubber seal is arranged between the actuating button and the switch, whereby the switch and the contacts are stored dust and moisture-proof.
Wie bereits angedeutet wurde, ist nach einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung vorgesehen, dass das Führungsgehäuse lösbar innerhalb der Endkappe befestigt ist, wozu das Führungsgehäuse vorzugsweise ein Außengewinde und die Endkappe vorzugsweise ein korrespondierendes Innengewinde besitzt, so dass das Führungsgehäuse in die Endkappe einschraubbar ist. Alternativ hierzu könnte das Führungsgehäuse auch mittels einer Steck-, Rast- oder Bajonettverbindung mit der Endkappe verbunden sein. Hiermit wird eine stabile und leicht zu montierende Möglichkeit geschaffen, den Schalter innerhalb einer Endkappe sicher zu lagern. Bemerkenswert ist dabei die geringe Anzahl von verwendeten Bauteilen, da neben der Endkappe, dem zweiteiligen Führungsgehäuse sowie dem Schalter keine weiteren Bauteile eingesetzt werden müssen, um einen funktionsfähigen Endkappenschalter zu realisieren. Hierdurch sinken nicht nur die Materialkosten, sondern auch die Montagekosten. Um einen sicheren, störungsfreien und stromführenden Kontakt zu gewährleisten, müssen die Kontakte, die als Blattfedern aus dem Führungsgehäuse herausragen, mit stromleitenden Teilen der Taschenlampe verbunden werden. Prinzipiell sind hierfür zwei verschiedene Möglichkeiten vorgesehen, die sich im Wesentlichen durch die Ausgestaltung des ersten Kontaktelementes unterscheiden, ohne dass die vorliegende Erfindung hierauf beschränkt ist. As already indicated, it is provided according to a particularly preferred embodiment of the present invention that the guide housing is releasably secured within the end cap, for which the guide housing preferably has an external thread and the end cap preferably has a corresponding internal thread, so that the guide housing can be screwed into the end cap , Alternatively, the guide housing could also be connected by means of a plug-in, latching or bayonet connection with the end cap. This provides a stable and easy-to-install way to safely store the switch within an end cap. Noteworthy here is the small number of components used, since in addition to the end cap, the two-part guide housing and the switch no other components must be used to realize a functional Endkappenschalter. This not only reduces the material costs, but also the assembly costs. In order to ensure a safe, trouble-free and energized contact, the contacts, which protrude as leaf springs from the guide housing, must be connected to current-carrying parts of the flashlight. In principle, two different possibilities are provided for this purpose, which differ essentially by the configuration of the first contact element, without the present invention being limited thereto.
Bei beiden Ausführungsformen durchgreift das zweite Kontaktelement eine Ausnehmung des Führungsgehäuses und bildet an dessen Stirnseite im zusammengebauten Zustand einen elektrischen Kontakt zu einem Pol der Batterie oder des Akkumulators. Hierdurch wird einerseits vermieden, dass der Strom über eine Spiralfeder fließt, andererseits kann der als gebogene Blattfeder ausgestaltete Kontakt fest anliegend mit dem Pol verbunden werden. Zur stabilen Halterung des zweiten Kontaktelements ist dessen freies Ende vorzugsweise in einer L-förmigen Ausnehmung innerhalb der Stirnseite des Führungsgehäuses angeordnet. Alternativ hierzu kann die Blattfeder auch über eine kleine Schraube oder ein anderes Befestigungsmittel fixiert werden. In both embodiments, the second contact element engages through a recess of the guide housing and forms on the end face in the assembled state an electrical contact to a pole of the battery or the accumulator. In this way, on the one hand avoided that the current flows through a coil spring, on the other hand, designed as a bent leaf spring contact can be tightly connected to the pole. For stable mounting of the second contact element whose free end is preferably arranged in an L-shaped recess within the end face of the guide housing. Alternatively, the leaf spring can also be fixed via a small screw or other fastening means.
Nach einer ersten bevorzugten Ausführungsform des ersten Kontaktelements durchgreift dieses eine Ausnehmung des Führungsgehäuses und bildet im zusammengebauten Zustand einen elektrischen Kontakt zu dem Taschenlampengehäuse. Hierzu ist die Ausnehmung an der Stirnseite des Führungsgehäuses ausgebildet, wobei der erste Kontakt als gebogene Blattfeder ausgestaltet ist und die Ausnehmung durchgreift und der herausragende Teil des Kontaktes den zylinderförmigen Mantel des Führungsgehäuses stirnseitig zumindest teilweise umgreift, so dass ein Kontakt- schluss zum Taschenlampengehäuse besteht, das hierzu vorzugsweise einen sockeiförmigen Vorsprung als Anlagefläche und elektrische Kontaktfläche besitzt. Dadurch, dass die Endkappe auf das Taschenlampengehäuse aufgeschraubt werden kann, kann der Druck, mit dem das erste Kontaktelement an den sockeiförmigen Vorsprung gedrückt wird, beliebig gewählt werden, so dass dort ein äußerst fester und sicherer Kontakt geschaffen wird. Zudem ergibt sich bei dieser Ausgestaltung der Vorteil, dass der Strom nicht über die Endkappe sondern direkt auf das Ta- schenlampengehäuse geführt wird, womit gegenüber herkömmlichen Taschenlampen eine Kontaktfläche, nämlich von der Endkappe auf das Taschenlampengehäuse, eingespart wird. According to a first preferred embodiment of the first contact element, this engages through a recess of the guide housing and forms an electrical contact with the flashlight housing in the assembled state. For this purpose, the recess is formed on the end face of the guide housing, wherein the first contact is designed as a bent leaf spring and engages through the recess and the protruding part of the contact, the cylindrical shell of the guide housing at least partially surrounds the end, so that a contact closure to the flashlight housing, for this purpose preferably has a sockeiförmigen projection as a contact surface and electrical contact surface. The fact that the end cap can be screwed onto the flashlight housing, the pressure with which the first contact element is pressed against the sockeiförmigen projection can be chosen arbitrarily, so that there is an extremely solid and secure contact is created. In addition, this embodiment provides the advantage that the current does not flow via the end cap but directly onto the tab. barrel lamp housing is performed, which compared to conventional flashlights a contact surface, namely from the end cap on the flashlight housing, is saved.
Nach einer alternativen Ausführungsform ist vorgesehen, dass das erste Kontaktelement eine Ausnehmung des Führungsgehäuses durchgreift und im zusammengebauten Zustand einen elektrischen Kontakt zu der Endkappe bildet. Hierzu ist die Ausnehmung an der Mantelfläche des Führungsgehäuses ausgebildet, wobei der erste Kontakt diese Ausnehmung durchgreift und das aus der Ausnehmung herausragende Ende des Kontaktes auf einer kragenförmigen Auflagefläche liegt, die zumindest bereichsweise radial von der Manteloberfläche des Führungsgehäuses absteht, so dass im zusammengebauten Zustand ein Kontaktschluss zur Endkappe besteht, in der das Führungsgehäuse lösbar fixiert ist. Die Auflagefläche kann dabei als ringförmige Verlängerung der Stirnseite des Führungsgehäuses ausgebildet sein. Mit anderen Worten, das erste Kontaktelement wird zwischen einer Auflagefläche des Führungsgehäuses und der Endkappe eingeklemmt, so dass beim Einschrauben des Führungsgehäuses in die Endkappe ein sicherer Kontakt durch einen hohen Druck geschaffen wird. Zwar wird bei dieser Ausführungsform der Strom über die Endkappe geführt, womit eine weitere Kontaktfläche zwischen Endkappe und Taschenlampengehäuse in Kauf genommen wird, allerdings ist der erste Kontakt bei dieser Ausführungsform vor Staub und Dreck sicherer gelagert, so dass ein Batteriewechsel vor allem in staubigen und dreckigen Umgebungen mit geringen Risiken verbunden ist, die Kontaktfläche zu verunreinigen, womit der elektrische Kontakt unter Umständen gestört werden könnte. According to an alternative embodiment, it is provided that the first contact element engages through a recess of the guide housing and forms an electrical contact with the end cap in the assembled state. For this purpose, the recess is formed on the lateral surface of the guide housing, wherein the first contact engages through this recess and the protruding from the recess end of the contact on a collar-shaped bearing surface which projects at least partially radially from the outer surface of the guide housing, so that in the assembled state Contact closure to the end cap is in which the guide housing is releasably fixed. The support surface may be formed as an annular extension of the end face of the guide housing. In other words, the first contact element is clamped between a support surface of the guide housing and the end cap, so that when screwing the guide housing into the end cap secure contact is created by a high pressure. Although the current is passed over the end cap in this embodiment, whereby a further contact surface between the end cap and flashlight housing is accepted, however, the first contact in this embodiment is stored safely from dust and dirt, so that a battery change especially in dusty and dirty Low-risk environments involve contaminating the contact surface, which may interfere with electrical contact.
Der Schalter besitzt ein einfaches Plastikgehäuse, aus dem neben den Kontaktelementen auch ein Betätigungselement hervorsteht. Nach einer bevorzugten The switch has a simple plastic housing from which protrudes in addition to the contact elements and an actuator. After a preferred
Ausgestaltung ist vorgesehen, dass das Betätigungselement axial beweglich ist und/oder stirnseitig eine elektrisch leitende Kontaktplatte besitzt, die mit beiden Kontaktelementen gleichzeitig verbindbar ist. Hierdurch wird eine einfache Möglichkeit geschaffen, einen Druckschalter mit möglichst wenig Kontakten zu bilden. Alternativ hierzu kann ein Kontaktelement innerhalb des Gehäuse als gebogene Blattfeder ausgebildet sein, die im entspannten Zustand von dem anderen Kontaktelement beabstandet ist, wobei beide Kontaktelemente durch das Betätigungselement gegen die Kraft der Blattfeder verbindbar sind. Durch diese Maßnahme wird gegenüber der Alternativen mit einer Kontaktplatte ein weiterer Kontakt eingespart. In beiden alternativen Ausführungsformen ist allerdings vorteilhafter Weise vorgesehen, dass das Betätigungselement ein Druck- oder Drehknopf ist, der gegen die Kraft einer Spiralfeder axial bewegbar ist. Hierdurch wird das Betätigungselement im entspannten Zustand von den Kontakten beabstandet gehalten, so dass ein ungewolltes An- oder Ausschalten der Taschenlampe verhindert wird. Embodiment is provided that the actuating element is axially movable and / or frontally has an electrically conductive contact plate which is connectable to both contact elements simultaneously. As a result, an easy way is created to form a pressure switch with as few contacts. Alternatively, a contact element may be formed within the housing as a bent leaf spring, which is spaced in the relaxed state of the other contact element, wherein both contact elements are connected by the actuating element against the force of the leaf spring. By this measure, a further contact is saved compared to the alternatives with a contact plate. In both alternative embodiments, however, it is advantageously provided that the actuating element is a pressure or rotary knob which is axially movable against the force of a spiral spring. As a result, the actuating element is kept at a distance from the contacts in the relaxed state, so that unintentional switching on or off of the flashlight is prevented.
Schließlich sind nach einer weiteren vorteilhaften Ausgestaltung der Erfindung Rastelemente am Bestätigungselement vorgesehen, so dass eine Tastfunktion oder wahlweise eine permanente Schaltfunktion einstellbar ist. Hiermit wird nicht nur die Handhabbarkeit der Taschenlampe, sondern auch die Funktionalität erhöht. Finally, locking elements are provided on the confirmation element according to a further advantageous embodiment of the invention, so that a tactile function or optionally a permanent switching function is adjustable. This not only increases the handling of the flashlight, but also the functionality.

The guide housing 13 has an external thread 17, so that it can be screwed with the integrated switch 1 into an end cap 6 (FIG. 1f, FIG. 2f). This end cap 6 in turn is connected to a flashlight housing 8 to the finished flashlight (Fig. 1g, Fig. 2g).
Wie bereits vorstehend erläutert wurde, sind für den Kontaktschluss zwischen dem ersten Kontaktelement 4 und dem Taschenlampengehäuse 7 im Wesentlichen zwei Möglichkeiten vorgesehen, die insbesondere in Fig. 1f, Fig. 1g und Fig. 2f dargestellt sind. Bei der Ausführungsform nach Fig. 1f ist die Ausnehmung 16 für das erste Kontaktelement 4 an der Stirnseite 18 des Führungsgehäuses 13 angeordnet. Das freie Ende des Kontaktelementes 4 umgreift den mantelförmigen Teil des Führungsgehäuses 13 teilweise (siehe Pfeil 19). Im zusammengebauten Zustand (Fig. 1g) wird das Kontaktelement 4 auf einen sockeiförmigen Vorsprung 111 innerhalb des Taschenlampengehäuses 7 gedrückt, womit ein elektrischer Kontaktschluss entsteht. As already explained above, essentially two possibilities are provided for the contact closure between the first contact element 4 and the flashlight housing 7, which are illustrated in particular in FIGS. 1f, 1g and 2f. In the embodiment according to FIG. 1f, the recess 16 for the first contact element 4 is arranged on the end face 18 of the guide housing 13. The free end of the contact element 4 surrounds the jacket-shaped part of the guide housing 13 partially (see arrow 19). In the assembled state (FIG. 1g), the contact element 4 is pressed onto a socke-shaped projection 111 within the flashlight housing 7, whereby an electrical contact closure is produced.
Bei der alternativen Ausführungsform (Fig. 2f) ist demgegenüber vorgesehen, dass die Ausnehmung 16 für den ersten Kontakt 4 mantelseitig des Führungsgehäuses 13 angeordnet ist, und im Anschluss hieran auf einer Auflagefläche 23 zum Liegen kommt.
