Description

Die Erfindung bezieht sich auf eine Niedervolt-Beleuchtungseinrichtung, mit einem parallelverlegten Stromschienenpaar und einem auf dem Stromschienenpaar verschiebbar geführten Stromabnehmerschlitten, der eine den Stromfluß zwischen den beiden Stromschienen unterbindende Isolierung und eine schwenkbare Halterung für eine an den beiden durch diese Isolierung voneinander elektrisch getrennten Schlittenteilen leitend angeschlossene Lampenfassung od. dgl. aufweist. Eine Niedervolt- Beleuchtungseinrichtung der eingangs geschilderten Art ist bereits aus der EP-A- 0 129 325 bekannt mit zwei Abnehmer kontakten zum elektrisch leitenden und mechanischen Kontakt zwischen dem Stromabnehmerschlitten und dem Stromschienen.The invention relates to a low-voltage lighting device, with a pair of busbars installed in parallel and a current collector carriage which is displaceably guided on the pair of busbars and which conducts insulation that prevents the flow of current between the two busbars and a pivotable holder for a slide part that is electrically separated from the two by this insulation connected lamp holder or the like. A low-voltage lighting device of the type described at the outset is already known from EP-A-0 129 325 with two pickup contacts for electrically conductive and mechanical contact between the pantograph slide and the busbars.

Wie aus der EP-A1-0 171 326 hervorgeht, gibt es auch bereits eine solche Niedervolt-Beleuchtungseinrichtung der eingangs geschilderten Art im Zusammenhang mit einer Aufhängevorrichtung für Bilder od.dgl., wobei am in sich starren Abnehmerschlitten zwei voneinander isolierte Schwenkarme angelenkt sind, die zwischen ihren freien Enden schwenkbar ein Lampengehäuse aufnehmen und zur elektrisch leitenden Verbindung zwischen den einzelnen Stromschienen und dem Lampengehäuse dienen. Diese Beleuchtungseinrichtung baut daher verhältnismäßig groß und sperrig, sie erlaubt außerdem nur ein Verschwenken der Lichtquelle um eine zur Schlittenführung querliegende Achse und außerdem kommt es häufig zu Kontaktschwierigkeiten in den Scharnierbereichen zwischen Schlitten und Schwenkarmen bzw. Schwenkarmen und innerhalb des Lampengehäuses sitzender Lampenfassung.As is apparent from EP-A1-0 171 326, there is already such a low-voltage lighting device of the type described at the outset in connection with a hanging device for pictures or the like, two pivot arms which are insulated from one another being articulated on the rigid sled carriage, which pivotally accommodate a lamp housing between their free ends and for the electrically conductive connection between the serve individual busbars and the lamp housing. This lighting device is therefore relatively large and bulky, it also only allows the light source to be pivoted about an axis lying transversely to the slide guide and, moreover, there are often contact difficulties in the hinge areas between the slide and swivel arms or swivel arms and the lamp holder seated within the lamp housing.

Gemäß der DE-A-3 151 996 wurde auch schon eine Niedervolt-Beleuchtungseinrichtung vorgeschlagen, die einen auf dem Stromschienenpaar verschiebbar aufgesetzten klotzförmigen Stromabnehmeer aufweist, der eine Aufnahmemulde und einen Magneten zur Aufnahme einer Lampe mit Kugelgehäuse aufweist. Hier muß die Stromverbindung zwischen Abnehmerschlitten und Lampe über ein eigenes Kabel geschlossen werden und die Halterung der Lampe über Magnetkräfte bleibt wegen der durch die oft hohen Stromstärken der Niedervoltanlagen bedingten elektromagnetischen Felder recht unsicher. Dazu kommt noch, daß trotz der freien Verschwenkbarkeit des Kugelgehäuses innerhalb der Aufnahmemulde der mögliche Beleuchtungsbereich durch den Stromabnehmerklotz selbst beträchtlich eingeschränkt ist.According to DE-A-3 151 996, a low-voltage lighting device has also been proposed which has a block-shaped current collector which is slidably mounted on the pair of busbars and which has a receiving trough and a magnet for receiving a lamp with a ball housing. Here, the power connection between the pick-up carriage and the lamp must be closed using a separate cable, and the mounting of the lamp using magnetic forces remains rather unsafe due to the electromagnetic fields caused by the often high currents of the low-voltage systems. In addition, despite the free pivotability of the ball housing within the receiving trough, the possible lighting area is considerably restricted by the pantograph block itself.

Der Erfindung liegt daher die Aufgabe zugrunde, diese Mängel zu beseitigen und eine Niedervolt-Beleuchtungseinrichtung zu schaffen, die sich durch ihre platzsparende, kompakte Bauweise, ihre Robustheit und Funktionssicherheit und vor allem durch ihre Schwenkfreiheit und ihren allseitigen Leuchtbereich auszeichnet.The invention is therefore based on the object of eliminating these deficiencies and of creating a low-voltage lighting device which is distinguished by its space-saving, compact design, its robustness and functional reliability and, above all, by its freedom of pivoting and its all-round lighting area.

Die Erfindung löst diese Aufgabe dadurch, daß bei einer Niedervolt- Beleuchtungseinrichtung der eingangs geschilderten Art der Abnehmerschlitten aus zwei auf den Schienen verschiebbar sitzenden Abnehmerköpfen und einem zwischen den Abnehmerköpfen um eine zur Schlittenführungsrichtung normale Querachse drehbar gelagerten Fassungsträger besteht, wobei der an den Abnehmerköpfen elektrisch leitend angelenkte Fassungsträger durch ein die Isolierung bildendes Zwischenstück unterteilt und selbst als Halterung und Stromanschluß der Lampenfassung vorgesehen ist. Die Lampenfassung bzw. die Lampe sitzt daher unmittelbar am den frei drehbar gelagerten Mittelteil des Abnehmerschlittens bildenden Fassungsträger und kann so wunschgemäß zwischen den Abnehmerköpfen verdreht werden. Es sind keine eigenen Schwenkarme erforderlich und keine Drahtverbindungen, und es entsteht auf kleinsten Raum eine kompakte, stabile Beleuchtungseinrichtung.The invention solves this problem in that in a low-voltage lighting device of the type described above, the pick-up carriage consists of two pick-up heads which are displaceably seated on the rails and there is a mount support which is rotatably mounted between the pickup heads about a transverse axis normal to the slide guide direction, the mount support which is articulated in an electrically conductive manner on the pickup heads being divided by an intermediate piece which forms the insulation and is itself provided as a holder and power connection for the lamp holder. The lamp holder or the lamp is therefore seated directly on the frame support forming the freely rotatable middle part of the pick-up carriage and can thus be rotated between the pick-up heads as desired. No separate swivel arms are required and no wire connections, and a compact, stable lighting device is created in the smallest space.

Um den Schwenkbereich der Lampenfassung um eine weitere Dimension zu vergrößern, weist nach einer besonders vorteilhaften Ausgestaltung der Erfindung der Fassungsträger zur Halterung der Lampenfassung einen Aufnahmearm auf, der um eine Normalachse zur Fassungsträger-Drehachse drehbar zwischem dem einen Fassungsträgerteil und einem leitend am anderen Fassungsträgerteil angesetzten Haltebügel lagert, wobei der beiderends elektrisch leitend abgestützte Aufnahmearm wie der Fassungsträger durch ein isolierendes Zwischenstück unterteilt ist und seinerseits die Lampenfassung aufnimmt. Es ergibt sich als Halterung für die Lampenfassung ein selbstleitendes Kardangelenk, so daß die Lampe allseitig ausgerichtet werden kann und es zu einem praktisch uneingeschränkten Leuchtbereich kommt. Trotz der Schwenkfreiheit bleibt aber der Platzbedarf minimal und die selbstleitenden Träger- und Armteile gewährleisten den drahtlosen Stromanschluß an die Stromschienen und sichern einen störunanfälligen, langlebigen Betrieb.In order to enlarge the pivoting range of the lamp holder by a further dimension, according to a particularly advantageous embodiment of the invention, the holder for holding the lamp holder has a receiving arm which is rotatable about a normal axis to the holder axis of rotation between the one holder part and one attached to the other holder part Bracket supports, the receiving arm, which is supported on both ends in an electrically conductive manner, is divided by an insulating intermediate piece and the lamp holder, in turn, and receives the lamp holder. The result is a self-conducting universal joint as a holder for the lamp holder, so that the lamp can be aligned on all sides and there is a practically unrestricted lighting area. Despite the freedom of swiveling, however, the space requirement remains minimal and the self-conducting support and arm parts ensure the wireless power connection to the power rails and ensure trouble-free, long-lasting operation.

Bestehen erfindungsgemäß Fassungsträger und gegebenenfalls Aufnahmearm jeweils aus zwei Metallbüchsen, die beidseits auf das scheibenförmige, Steckzapfen bildende Zwischenstück aufgesteckt sind, ergibt sich eine einfache, aufwandsarme Konstruktion, die optimal zur Erfüllung einerseits ihrer isolierenden, anderseits ihrer stromführenden Aufgaben geeignet ist.If, according to the invention, the mount support and, if applicable, the receiving arm each consist of two metal bushings, which are fitted on both sides of the disc-shaped, plug-in intermediate piece, this results in a simple, low-cost construction that is optimally suited to fulfilling on the one hand its insulating and on the other hand its current-carrying tasks.

Günstig ist es auch, wenn ein Steckpolepaar die Lampenfassung bildet, dessen Steckpole beiderseits des Zwischenstückes in den beiden Fassungsträger- oder Aufnahmearmteilen eingesetzt sind, da eine besonders aufwandsarme, platzsparende und auch robuste Lampenfassung entsteht.It is also advantageous if a pair of plug-in poles forms the lamp socket, the plug-in poles of which are inserted on both sides of the intermediate piece in the two socket support or receiving arm parts, since a particularly inexpensive, space-saving and also robust lamp socket is produced.

Ragen dabei die Steckpole radial einwärts durch die Metallbüchsen hindurch bis in die Steckzapfen des Zwischenstückes, lassen sich diese Steckpole gleichzeitig zum Fixieren des Zwischenstückes gegenüber den Metallbüchsen verwenden, was den Aufbau weiter vereinfacht.If the plug-in poles protrude radially inwards through the metal bushes into the plug-in pins of the intermediate piece, these plug-in poles can simultaneously be used to fix the intermediate piece in relation to the metal bushes, which further simplifies the construction.

Um eine gute, widerstandsarme Leitungsverbindung zwischen den relativ zueinander verdrehbaren Teilen zu erreichen, können zur Drehlagerung des Fassungsträgers oder des Aufnahmearmes die Metallbüchsen mit einer stirnseitigen Lagerbohrung auf einem in den sie abstützenden Teil eingesetzten metallenen Lagerbolzen aufgesteckt und zwischen dem Abstützteil und einem Bolzenkopf über eine metallene Feder verspannt sein. Es kommt zu einer im gewissen Sinne selbsthemmenden Verdrehbarkeit des Fassungsträgers gegenüber den Abnehmerköpfen bzw. des Aufnahmearmes gegenüber dem Fassungsträger bzw. seinem Haltebügel, wodurch die Lampenfassung in jeder Drehstellung lagesicher verbleibt, und außerdem wird über die federnde Verspannung der Teile für einwandfreie Stromführungskontakte gesorgt.In order to achieve a good, low-resistance line connection between the parts which can be rotated relative to one another, the metal bushings with a front-side bearing bore can be plugged onto a metal bearing pin inserted in the supporting part and rotatably mounted between the supporting part and a bolt head via a metal one for the rotary mounting of the socket carrier or the receiving arm Spring tensioned. In a certain sense, there is a self-locking rotatability of the holder in relation to the pick-up heads or the receiving arm in relation to the holder or its retaining bracket, as a result of which the lamp holder remains securely in any rotational position, and the resilient tensioning of the parts also ensures that it is in perfect condition Current supply contacts provided.

In der Zeichnung ist der Erfindungsgegenstand schematisch veranschaulicht, und zwar zeigen

  • Fig. 1 eine erfindungsgemäße Niedervolt-Beleuchtungseinrichtung im perspektivischen Schaubild und
  • Fig. 2 und 3 zwei Ausführungsbeispiele des Abnehmerschlittens dieser Beleuchtungseinrichtung im teilgeschnittenen Schaubild unterschiedlichen Maßstabes.
In the drawing, the subject matter of the invention is illustrated schematically, namely show
  • Fig. 1 shows a low-voltage lighting device according to the invention in a perspective diagram and
  • 2 and 3 show two exemplary embodiments of the pick-up carriage of this lighting device in a partially sectioned diagram of different scales.

Auf einem in nicht weiter dargestellter Weise an eine Niedervolt-Stromquelle angeschlossenen Stromschienenpaar 1, das über Schienenhalter 2 parallelverlaufend und gegeneinander isoliert in beliebiger Lage und Richtung verlegt werden kann, ist ein Stromabnehmerschlitten 3 verschiebbar geführt, der mit zwei Abnehmerköpfen 4 auf den Stromschienen 1 sitzt und durch Klemmschrauben 5, die in die schlitz- oder lochförmigen Führungen 6 der Abnehmerköpfe 4 eindringen, in jeder Verschiebepostition fixierbar ist. Der Abnehmerschlitten 3 weist einen zwischen den Abnehmerköpfen 4 um eine zu den Führungsbohrungen 6 normale Querachse A drehbar gelagerten Fassungsträger 7 für die Lampenfassung einer Niedervoltlampe L auf, der seinerseits durch ein isolierendes Zwischenstück 8 unterteilt ist, wobei der Fassungsträger 7 aus zwei Metallbüchsen 7a, 7b besteht, die gegengleich auf das scheibenförmige, beidseits Steckzapfen 8a bildende Zwischenstück aufgesteckt sind. Zur Anlenkung des Fassungsträgers 7 an den Abnehmerköpfen 4 gibt es jeweils einen eine stirnseitige Lagerbohrung 9 der Metallbüchsen 7a, 7b durchragenden, im benachbarten Abnehmerkopf 4 eingesetzten Lagerbolzen 10 und eine sich an einem Bolzenkopf 10a und an der Metallbüchse 7a,7b abstützende metallene Feder 11 sorgt für eine Verspannung zwischen Metallbüchse 7a, 7b und Abnehmerkopf 4. Es entsteht eine elektrisch gut leitende, selbsthemmende Drehlagerung des Fassungsträgers 7 an den Abnehmerköpfen 4.On a pair of busbars 1 which is connected to a low-voltage power source in a manner not shown and which can be laid parallel to one another and insulated from one another in any position and direction, a pantograph carriage 3 is slidably mounted on the busbars 1 with two pickup heads 4 and can be fixed in any displacement position by means of clamping screws 5 which penetrate the slot-shaped or hole-shaped guides 6 of the pick-up heads 4. The pick-up slide 3 has a holder 7 for the lamp holder of a low-voltage lamp L, which holder is rotatably mounted between the holder heads 4 about a transverse axis A normal to the guide bores 6 and which is in turn divided by an insulating intermediate piece 8, the holder 7 consisting of two metal bushings 7a, 7b there are, which are plugged in opposite directions on the disc-shaped, on both sides spigot 8a forming intermediate piece. For the articulation of the holder 7 on the pick-up heads 4, there is in each case a bearing pin 9 projecting through an end-side bearing bore 9 of the metal bushings 7a, 7b and inserted in the adjacent pick-up head 4, and one on a bolt head 10a and on the metal bushing 7a, 7b Supporting metal spring 11 ensures tension between the metal bushing 7a, 7b and the pick-up head 4. An electrically well-conductive, self-locking rotary bearing of the holder 7 on the pick-up heads 4 is produced.

Wie in Fig. 2 angedeutet, kann nun der Fassungsträger 7 unmittelbar selbst Halterung und Fassung für die Niedervoltlampe 11 bilden, wozu als Lampenfassung ein Steckpolepaar 12 beidseits des Zwischenstückes 8 in die Metallbüchsen 7a, 7b des Fassungsträgers 7 eingesetzt sind, welche Steckpole 12 gleichzeitig zur Sicherung des Zusammenhaltes des Fassungsträgers 7 durch die Metallbüchsen 7a, 7b hindurchragen und in die Steckzapfen 8a des Zwischenstückes 8 eingreifen. Da die Steckpole 12 durch ihren Sitz in den Metallbüchsen 7a, 7b unmittelbar an den beiden durch das Zwischenstück 8 voneinander elektrisch getrennten, stromführenden Schlittenteilen anschließen, ist die erforderliche Stromversorgung einer in die Steckpole 12 eingesteckten Lampe 12 gewährleistet. Diese Lampe läßt sich dabei durch Verschieben des Abnehmerschlittens 3 beliebig entlang des Stromschienenpaares 1 positionieren und durch Verdrehen des Fassungsträgers 7 in jede Schwenkrichtung um die Querachse A verdrehen.As indicated in Fig. 2, the socket holder 7 can now directly form the holder and socket for the low-voltage lamp 11, for which purpose a pair of plug-in poles 12 are inserted on both sides of the intermediate piece 8 into the metal bushings 7a, 7b of the socket holder 7, which plug-in poles 12 simultaneously Securing the cohesion of the frame support 7 protrude through the metal bushings 7a, 7b and engage in the plug pins 8a of the intermediate piece 8. Since the plug-in poles 12 connect directly through their seat in the metal bushings 7a, 7b to the two current-carrying slide parts which are electrically separated from one another by the intermediate piece 8, the required power supply for a lamp 12 plugged into the plug-in poles 12 is ensured. This lamp can be positioned as desired along the pair of busbars 1 by moving the pick-up carriage 3 and rotated about the transverse axis A in each pivoting direction by rotating the socket support 7.

Um eine größere Schwenkfreiheit zu erreichen, kann, wie in Fig. 3 veranschaulicht, der Fassungsträger 7 mit einem Aufnahmearm 13 ausgestattet sein, der um eine Normalachse B zur Querachse A drehbar zwischen der einen Metallbüchse 7b bzw. einem passend auf die Metallbüchse 7b aufsetzbaren sattelförmigen Ansatzstück 7c des Fassungsträgers 7 und einem in die andere Metallbüchse 7a eingesetzten metallenen Haltebügel 14 lagert und sich ähnlich wie der Fassungsträger 7 aus zwei Metallbüchsen 13a, 13b und einem isolierenden Zwischenstück 15 zusammensetzt. Auch hier sind zur elektrisch leitenden Drehlagerung Lagerbolzen 10 und die relativ zueinander verdrehbaren Teile miteinander verspannende Federn 11 vorgesehen und das Steckpolepaar 12 bildet die Lampenfassung, wobei die Steckpole 12 wiederum in das Innere der Metallbüchsen 13a, 13b hineinragen und in die Steckzapfen 15a des Zwischenstückes 15 eingreifen. Es entsteht eine Beleuchtungseinrichtung, deren Lampe nicht nur entlang des Schienenpaares 1 längsverschiebbar und um die Querachse A verschwenkbar, sondern zusätzlich auch um eine Normalachse B verdrehbar ist, so daß praktisch ein allseitig nutzbarer Leuchtbereich zur Verfügung steht.In order to achieve greater freedom of pivoting, as illustrated in FIG. 3, the mount carrier 7 can be equipped with a receiving arm 13 which can be rotated about a normal axis B to the transverse axis A between the one metal bushing 7b or a saddle-shaped one which can be fitted onto the metal bushing 7b Attachment 7c of the holder 7 and a metal bracket 14 inserted into the other metal sleeve 7a is stored and is similar to the holder 7 made of two metal sleeves 13a, 13b and an insulating intermediate piece 15 composed. Here, too, bearing pins 10 and the springs 11 which clamp the mutually rotatable parts are provided for the electrically conductive rotary bearing, and the plug-in pole pair 12 forms the lamp holder, the plug-in poles 12 in turn projecting into the interior of the metal bushes 13a, 13b and into the plug-in pins 15a of the intermediate piece 15 intervention. The result is a lighting device, the lamp of which is not only longitudinally displaceable along the rail pair 1 and pivotable about the transverse axis A, but can also be rotated about a normal axis B, so that practically a usable lighting area is available.
