Description

Tragbare elektrische Leuchte Portable electric light
Die vorliegende Erfindung liegt auf dem Gebiet der tragbaren elektrischen Leuchten und betrifft eine Leuchte mit einer flexiblen Halterung gemass dem Oberbegriff des ersten Patentanspruchs .The present invention is in the field of portable electric lights and relates to a light with a flexible bracket according to the preamble of the first claim.
Verhaltnismassig kleine, leichte und bezüglich Energieversorgung autonome, d. h. tragbare Leuchten, die auf flexiblen Halterungen montiert sind, können an einem gewünschten Ort positioniert und in eine gewünschte Richtung ausgerichtet werden, um Flachen oder Gegenstande optimal zu beleuchten. Deshalb haben sie eine grosse Vielfalt an Verwendungsmöglichkeiten, bspw. zur Beleuchtung eines Werkstucks an einer Werkbank, als Leselicht, für eine Punktformige Beleuchtung im Nasszellenbereich etc.Relatively small, light and autonomous in terms of energy supply, i. H. Portable lights that are mounted on flexible brackets can be positioned and oriented in a desired direction to optimally illuminate surfaces or objects. That is why they have a wide variety of possible uses, e.g. for illuminating a workpiece on a workbench, as a reading light, for spot lighting in the wet room area, etc.
Eine gattungsgemasse Leuchte ist aus der Schrift EP-0'683'345 Bl bekannt. Diese Leuchte umfasst ein Basisgehause mit einerA generic lamp is known from the document EP-0'683'345 Bl. This lamp comprises a basic housing with a
Öffnung zur Aufnahme von Batterien, ein Arbeitsendgehause mit einer Lampe und eine das Basisgehause mit dem Arbeitsendgehause verbindende flexible Kernanordnung. Die flexible Kernanordnung weist ein Paar leitfahiger Drahte, welche die Batterie elektrisch mit der Lampe verbinden und von einer flexiblen Befestigungsanordnung umgeben sind, auf. Die flexible Befestigungsanordnung weist mehrere miteinander verbundene und universell drehbare Elemente auf, die mit einem elastischen Hulsenelement n Eingriff stehen.Opening for receiving batteries, a working end housing with a lamp and the base housing with the Flexible core arrangement connecting work end housing. The flexible core assembly has a pair of conductive wires that electrically connect the battery to the lamp and are surrounded by a flexible attachment assembly. The flexible fastening arrangement has a plurality of interconnected and universally rotatable elements which are in engagement with an elastic sleeve element.
Diese aus dem Stand der Technik bekannte Leuchte hat den Nachteil, dass die Leuchte wegen der elektrischen Leitungen zur Speisung der Lampe storungsanfallig oder technisch aufwandig ist. Die flexible Kernanordnung muss derart gestaltet sein, dass auch be extremen Biege- und/oder Zugbelastungen die Leitungen nicht durch Einklemmen beschädigt und nicht freigelegt werden. Dies bedingt eine spezielle Bauweise der universell drehbaren Elemente der flexiblen Kernanordnung auf, die unter allen Umstanden verhindert, dass sich die Elemente voneinander losen können.This luminaire known from the prior art has the disadvantage that the luminaire is susceptible to faults or is technically complex because of the electrical lines for feeding the lamp. The flexible core arrangement must be designed in such a way that the lines are not damaged by pinching and are not exposed even in the event of extreme bending and / or tensile loads. This requires a special design of the universally rotatable elements of the flexible core arrangement, which in all circumstances prevents the elements from becoming detached from one another.
Ein weiterer Nachteil der aus dem Stand der Technik bekannten Leuchte besteht darin, dass der Durchgang der elektrischen Leitungen von der flexiblen Kernanordnung in das Arbeitsendgehause gut abgedichtet werden muss, um ein Eindringen von Feuchtigkeit und Verunreinigungen in das Arbeitsendgenause zu verhindern. Besonders für Anwendungen in rauen Umgebungen, wie z. B. an Werkbanken, wird die Abdichtung aufwandig und kostspielig. Es ist eine Aufgabe der vorliegenden Erfindung, eine Leuchte der eingangs genannten Art zu schaffen, welche die obigen Nachteile vermeidet.A further disadvantage of the luminaire known from the prior art is that the passage of the electrical lines from the flexible core arrangement into the working end housing must be well sealed in order to prevent moisture and contaminants from penetrating into the working end. Especially for applications in harsh environments, such as B. on workbenches, the seal is complex and expensive. It is an object of the present invention to provide a luminaire of the type mentioned at the outset which avoids the above disadvantages.
Die Aufgabe wird gelost durch die tragbare elektrische Leuchte, wie sie im ersten Patentanspruch definiert ist. Vorteilhafte Ausfuhrungsformen sind in den abhangigen Patentansprüchen aufgeführt.The task is solved by the portable electric light as defined in the first claim. Advantageous embodiments are listed in the dependent claims.
Die erfmdungsgemasse Leuchte umfasst eine Batterieaufnahmestelle, ein Gehäuse, welches eine mit der Batterieaufnahmestelle elektrisch verbundene elektrische Lichtquelle beinhaltet, und eine mit dem Gehäuse verbundene flexible Halterung, welche mehrere identische, jeweils paarweise miteinander verbundene und bezuglich mindestens einer Achse gegeneinander drehbare Glieder aufweist. Dabei ist die Batterieaufnahmestelle im Gehäuse untergebracht.The luminaire according to the invention comprises a battery receiving point, a housing which contains an electrical light source which is electrically connected to the battery receiving point, and a flexible holder which is connected to the housing and has a plurality of identical links which are each connected in pairs and rotatable relative to one another with respect to at least one axis. The battery holder is located in the housing.
Die erfindungsgemasse Leuchte erlaubt eine gezielte Beleuchtung einer gewünschten Flache, indem die Lichtquelle an diese Flache herangeführt und beliebig positioniert werden kann. Trotzdem ist die Leuchte einfach, kostengünstig und nicht storungsanfallig. Sie kann gegenüber der Umgebung effizient aogedichtet werden. Diese und andere Vorteile werden insbesondere dadurch erzielt, dass keine elektrischen Leitungen durch die flexible Halterung hindurch fuhren. Nachfolgend werden beispielhafte Ausfuhrungsformen der Erfindung anhand von Zeichnungen detailliert beschrieben. Dabei zeigen:The luminaire according to the invention permits targeted illumination of a desired area, in that the light source is brought up to this area and can be positioned as desired. Nevertheless, the lamp is simple, inexpensive and not prone to malfunction. It can be efficiently sealed to the environment. These and other advantages are achieved in particular in that no electrical lines run through the flexible holder. Exemplary embodiments of the invention are described in detail below with reference to drawings. Show:

Eine Ausfuhrungsform der erfindungsgemassen Leuchte 1 ist in perspektivischer Ansicht in Figur 1 und im Längsschnitt in Figur 2 dargestellt. Die Leuchte 1 beinhaltet ein Gehäuse 2, in dem sich eine Aufnahmestelle 3 für Batterien 4.1, 4.2 und eine elektrische Lichtquelle 5 befindet. Ferner beinhaltet die Leuchte 1 eine mit dem Gehäuse 2 verbundene flexible rohrformige Halterung 6, welche mehrere identische, jeweils paarweise miteinander verbundene und bezuglich mindestens einer Achse gegeneinander drehbare Glieder 60.1, 60.2, ... aufweist .An embodiment of the lamp 1 according to the invention is shown in a perspective view in FIG. 1 and in a longitudinal section in FIG. The lamp 1 contains a housing 2, in which there is a receiving point 3 for batteries 4.1, 4.2 and an electric light source 5. Furthermore, the luminaire 1 contains a flexible tubular holder 6 connected to the housing 2, which has a plurality of identical links 60.1, 60.2,.
Das Gehäuse 2 kann zylinderformig sein, wobei der Zylindermantel von einer Hülse 21, bspw. einem Metallrohr, mit einem Aussendurchmesser von bspw. 14 mm und einer Lange von bspw. 32 mm gebildet wird. Nach vorn kann das Gehäuse 2 offen oder von einer durchsichtigen (nicht eingezeichneten) Scheibe aus Glas oder Kunststoff abgedeckt sein; es können auch optische Filter oder Linsen eingesetzt werden. Nach hinten, gegen die flexible Halterung 6 hin, ist das Gehäuse 2 vorzugsweise abgeschlossen und abgedichtet. Im Ausfuhrungsbeispiel der Figuren 1 und 2 wird der Gehauseabschluss von einem Adapterelement 7, das bspw. aus Metall besteht, gebildet. Das Adapterelement 7 weist ein Aussengewinde 72 auf, welches in ein auf der Innenwand der Hülse 21 angebrachtes Innengewinde 22 eingreift. An seinem der flexiblen Halterung 6 zugewandten Ende ist das Adapterelement 7 derart gestaltet, dass es mit dem ersten Glied 60.1 der flexiblen Halterung 6 eine Verbindung eingeht, die analog zur paarweisen Verbindung der Glieder 60.1, 60.2, ... untereinander ist, in diesem Fall also eine universell drehbare Schnappverbindung. Das Gehäuse 2 kann bei Bedarf spritzwasserdicht ausgeführt sein; vgl. auch Fig. 4.The housing 2 can be cylindrical, the cylinder jacket being covered by a sleeve 21, for example a metal tube, with an outer diameter of, for example, 14 mm and a length of, for example, 32 mm. To the front, the housing 2 can be open or covered by a transparent (not shown) pane made of glass or plastic; optical filters or lenses can also be used. To the rear, against the flexible holder 6, the housing 2 is preferably closed and sealed. In the exemplary embodiment of FIGS. 1 and 2, the housing end is formed by an adapter element 7, which consists, for example, of metal. The adapter element 7 has an external thread 72 which engages in an internal thread 22 attached to the inner wall of the sleeve 21. At its end facing the flexible holder 6, the adapter element 7 is designed such that it enters into a connection with the first link 60.1 of the flexible holder 6, which is analogous to the paired connection of the links 60.1, 60.2,... In this case thus a universally rotatable snap connection. The housing 2 can be made splash-proof if necessary; see. also Fig. 4.
Die elektrische Lichtquelle 5 ist z. B. eine Leuchtdiode (light-emitting diode, LED) , und zwar vorzugsweise eine annähernd weisses Licht aussendende Leuchtdiode. Leuchtdioden nutzen die vorhandene elektrische Energie effizient aus, sind leicht, klein und langlebig; deshalb sind sie für diese Art von Leuchten besonders geeignet. Es können aber auch andere elektrische Lichtquellen 5 für die erfindungsgemasse Leuchte 1 verwendet werden, bspw. Glühlampen wie in herkömmlichen Taschenlampen. Die beiden Sockelstifte 51, 52 der Leuchtdiode 5 sind in einem plattenformigen, im Gehäuse 2 befestigten und elektrisch isolierenden Sockel 23 verankert. Dabei steht ein erster Sockelstift 51 mit einem ersten Batteriepol 41, bspw. dem negativen, in Kontakt. Ein zweiter Sockelstift 52 steht über eine auf mindestens einer Seite des Sockels 23 aufgebrachten elektrisch leitenden Schicht 24 mit dem GehäuseThe electric light source 5 is, for. B. a light emitting diode (LED), preferably an approximately white light emitting diode. LEDs use the available electrical energy efficiently, are light, small and durable; therefore they are particularly suitable for this type of luminaire. However, other electrical light sources 5 can also be used for the lamp according to the invention 1 are used, for example incandescent lamps as in conventional flashlights. The two base pins 51, 52 of the light-emitting diode 5 are anchored in a plate-shaped base 23, which is fastened in the housing 2 and is electrically insulating. In this case, a first socket pin 51 is in contact with a first battery pole 41, for example the negative one. A second socket pin 52 stands over an electrically conductive layer 24 with the housing applied to at least one side of the socket 23

Um einen elektrischen Kontakt des zweiten Socl<elst ftes 52 mit dem ersten Batteriepol 41 zu verhindern, kann eine Isolierbeilage 25 zwischen dem Sockel 23 und der E3attene 4.1 eingelegt werden. Die Leuchtdiode 5 kann bspw. von einem Reflektorelement 26 umgeben sein.2 and thus in contact with a second battery pole 42, for example the positive one. In order to prevent electrical contact of the second socket 52 with the first battery pole 41, an insulating insert 25 can be inserted between the base 23 and the plate 4.1. The light emitting diode 5 can, for example, be surrounded by a reflector element 26.
Im Ausfuhrungsbeispiel der Figuren 1 und 2 werden zwei Knopfbatterien 4.1, 4.2 verwendet. Dies sind scneibenformige Batterien, αeren Durchmesser gleich gross oder grosser ist als ihre Hohe. Es können bspw. zwei in Serie geschaltete Batterien 4.1, 4.2 mit je einem Durchmesser von 11.5 mm, einer Hohe von 5.4 mm und einer Nennspannung von 1,5 V eingesetzt werden. Die Batterien 4.1, 4.2 werden von einem elektrisch isolierenden Druckstift 73, welcher mittels einer Druckfeder 74 gegen das Adapterelement 7 abgestutzt ist, gegen den Sockel 23 gedruckt. Der elektrische Stromkreis wird durch Verdrehen der Hülse 21 gegenüber dem Adapterelement 7 geschlossen ozw. unterbrochen. In Figur 2 ist ein Zustand mit unterbrochenem Stromkreis dargestellt. Werden, ausgehend von diesem zustand, die Hülse 21 und das Adapterelement 7 gegeneinander geschraubt, so kommt das Adapterelement mit dem zweiten Batteriepol 42 der zweiten Batterie 4.2 in Kontakt. Über das Adapterelement 7, die Hülse 21 und die elektrisch leitende Schicht 24 wird eine elektrische Verbindung zwischen dem zweiten Batteriepol 42 und dem zweiten Sockelstift 52 der Leuchtdiode 5 hergestellt.In the exemplary embodiment of FIGS. 1 and 2, two button batteries 4.1, 4.2 are used. These are disk-shaped batteries whose diameter is equal to or greater than their height. For example, two series-connected batteries 4.1, 4.2, each with a diameter of 11.5 mm, a height of 5.4 mm and a nominal voltage of 1.5 V, can be used. The batteries 4.1, 4.2 are pressed against the base 23 by an electrically insulating pressure pin 73, which is supported against the adapter element 7 by means of a pressure spring 74.

In the example of FIGS. 1 and 2, the foot 63 of the last link 60.1 comprises the end 75 of the adapter element 7, which is designed as a head. Of course, the flexible holder can also have links or elements that are compatible with the system than those identical to one another in FIGS. 1 and 2 shown links 60.1, 60.2, ... include, for example, a (not shown) reversing piece, which connects two heads 61 together. Any adapter, base or fastening elements can be attached to the free end 69 of the flexible holder 6, which is not connected to the housing 2, for example those with magnets, suction cups or clamps. This ensures a wide variety of possible uses for the luminaire 1.
Eine zweite Variante der erfindungsgemassen Leuchte 1 ist in Figur 3 dargestellt, wobei der Einfachheit halber nur das letzte Glied 60.1 der flexiblen Halterung 6 gezeigt ist. In diesem Ausfuhrungsbeispiel ist das Gehäuse 2 derart gestaltet, dass es sich auch als Schlusselanhanger eignen wurde. Es weist einen batterieseitigen Verschluss 8 auf, der mit einer zur Aufhangung an einem Schlüsselring bestimmten Ose 81 ausgestattet ist. Die Aussenseite der Ose 81 ist mit einem Aussengewinde 82 versehen, welches mit einem auf der Innenflache des letzten Gliedes der flexiblen Halterung angebrachten Innengewinde 64 zusammenwirkt und so eine Schraubverbindung zwischen dem Gehäuse 2 und der flexiblen Halterung 6 herstellt. Es ist vorteilhaft, die Schraubverbindung mit einem Klebstoff zu sichern und irreversibel zu machen. Auf diese Weise halt die Verbindung den Kräften stand, die beim Verstellen der flexiblen Halterung 6 entstehen. Ausserdem wird durch die Verklebung sichergestellt, dass ein Schrauben am Gehäuse 2 bei festgehaltenem Halterungsglied 60.1 ein Abschrauben des Verschlusses 8 bewirkt, um bspw. die Batterien auszuwechseln. Ohne Verklebung wäre nicht bestimmt, ob ein solches Schrauben das Abschrauben des Verschlusses 8 vom Gehäuse 2 oder vom Halterungsglied 60.1 zur Folge hatte. Es kann ein Schalter 27 zum Ein- und Ausschalten der Leuchte vorgesehen sein.A second variant of the luminaire 1 according to the invention is shown in FIG. 3, only the last link 60.1 of the flexible holder 6 being shown for the sake of simplicity. In this exemplary embodiment, the housing 2 is designed such that it would also be suitable as a key fob. It has a battery-side lock 8, which is equipped with an eyelet 81 intended for hanging on a key ring. The outside of the eyelet 81 is provided with an external thread 82 which interacts with an internal thread 64 provided on the inner surface of the last link of the flexible holder and thus one Establishes screw connection between the housing 2 and the flexible holder 6. It is advantageous to secure the screw connection with an adhesive and make it irreversible. In this way, the connection withstands the forces that arise when adjusting the flexible holder 6. In addition, the adhesive ensures that screwing on the housing 2, with the holding member 60.1 held in place, causes the closure 8 to be unscrewed, for example to replace the batteries. Without gluing, it would not be determined whether such screwing resulted in the closure 8 being unscrewed from the housing 2 or from the mounting member 60.1. A switch 27 can be provided for switching the lamp on and off.
Eine dritte Ausfuhrungsform der erfindungsgemassen Leuchte 1 zeigt schliesslich Figur 4. Die Darstellung ist ein Längsschnitt wie in Fig. 2, und analoge bzw. gleich wirkende Elemente werden mit denselben Bezugszeichen bezeichnet. Dementsprechend wird hier nicht mehr auf die bereits in Fig. 2 eingeführten Elemente eingegangen. Auf einige Details wurde in Fig. 4 der Einfachheit halber verzichtet.Finally, a third embodiment of the luminaire 1 according to the invention is shown in FIG. 4. The illustration is a longitudinal section as in FIG. 2, and elements which are analogous or have the same effect are designated by the same reference symbols. Accordingly, the elements already introduced in FIG. 2 are no longer discussed here. Some details have been omitted in FIG. 4 for the sake of simplicity.
Das Reflektorelement 26 ist in der Ausführungsform von Fig. 4 mittels eines Presssitzes in die Hülse 21 eingefugt. Das Adapterelement 7 kann mit einer Querbohrung 76 versehen sein, die, sollte das Gehäuse 2 einmal ohne flexible Halterung 6 verwendet werden, z. B. zur Aufnahme eines Schlüsselrings verwendet werden kann.In the embodiment of FIG. 4, the reflector element 26 is inserted into the sleeve 21 by means of a press fit. The adapter element 7 can be provided with a transverse bore 76 which, should the housing 2 be without a flexible holder 6 are used, e.g. B. can be used to hold a key ring.
Es kann - je nach Anwendung - erwünscht sein, das Gehäuse 2 wasserdicht gegen die Umgebung abzuschliessen . Zu diesem Zweck können zwei O-Ringe 28, 29 das Gehäuse 2 am vorderen und am hinteren Ende abdichten, wobei ein erster O-Ring 28 die Hülse 21 gegen das Reflektorelement und ein zweiter 0- Ring 29 die Hülse 21 gegen das Adapterelement 7 abdichtet. Es kann auch vorteilhaft sein, mit einem die Batterien 4.1, 4.2 seitlich umgebenden Isolationsrohr 31 die Batterien 4.1, 4.2 gegen die Hülse 21 zu isolieren. Depending on the application, it may be desirable to seal the housing 2 watertight against the environment. For this purpose, two O-rings 28, 29 can seal the housing 2 at the front and rear ends, a first O-ring 28 sealing the sleeve 21 against the reflector element and a second O-ring 29 sealing the sleeve 21 against the adapter element 7 , It can also be advantageous to isolate the batteries 4.1, 4.2 from the sleeve 21 with an insulation tube 31 which laterally surrounds the batteries 4.1, 4.2.
