Definitions
- the present invention relates to a light or an electrical unit that is provided for connection to a mounting rail, the mounting rail having a mounting rail profile with two side walls and at least one conductor rail arranged in the mounting rail profile with lines that can be contacted.
- Support rails with a support rail profile and a busbar held in the support rail profile are known from the prior art and are used, for example, to implement elongated so-called continuous lighting systems.
- a well-known light line system is sold by the applicant under the name "TECTON" and is characterized in that lights or other electrical loads can be flexibly positioned on the mounting rail over the entire length of the system. This is made possible by the fact that due to a special mounting of the lines of the busbar, these are accessible to consumers over essentially the entire length of the continuous lighting system, so that the lines can be contacted not only at fixed positions, but at any point.
- the WO 2001/091250 A1 such a lighting system.
- two conductor rails are arranged opposite one another on the two side walls of a U-shaped carrier rail profile that is open at the bottom.
- the lines of the busbars are then contacted by the lamp or consumer having a rotatable contacting element, which is inserted into the mounting rail from the underside and then rotated by approximately 45°.
- Contacts arranged on the contacting element are designed in such a way that they are pivoted out to the side as a result of the twisting and ultimately contact the lines of the busbars in the twisted state.
- the rotatable contacting elements described above were designed and mounted on the lamp or the electrical load in such a way that they could be actuated by a user from below the lamp, ie rotated.
- the lamp or a carrier element of the lamp or the consumer was then attached to the mounting rail from the underside, in which case the contacting element or elements was/were twisted in this state resting on the mounting rail.
- the contacting elements had to be accessible for actuation from the underside of the light or the consumer, which usually did not pose a problem, since elongated fluorescent lamps were usually used as the light sources, which were only switched on after the light was attached to the mounting rail could easily be used by the consumer in the sockets of the lamp.
- LEDs or LED circuit boards are predominantly used as illuminants in lighting technology, even in the case of luminaires that are intended for use with such mounting rails. Since the subsequent arrangement of LED lamps on a luminaire is not sensible or possible and, moreover, a uniform light output can only be achieved if the LEDs are arranged more or less continuously and evenly distributed over the entire length of the light line system, it is usually no longer possible to design the rotatable contacting elements explained above in such a way that they are accessible from the underside.
- FIG. 4 Such a solution known from the prior art is in figure 4 shown, with the elongate carrier element 110 of a so-called bar light 100 being visible here first, on which a contacting element 120 is rotatably mounted.
- the carrier element 110 present in the form of a profile element must be attached to the support rail of the continuous lighting system from the underside—not shown—and then the contacting element 120 must be rotated in order to mount the luminaire 100 .
- the carrier element 110 has side walls 111 on both longitudinal sides, an elongated slot 112 being formed on one side wall 111, through which the end region of a lever 125 connected to the contacting element 120 protrudes.
- the lever 125 can be pivoted along the slot 112 between the two positions shown, with a corresponding rotation of the contacting element 120 then also taking place.
- Contacts 122 of the contacting element 120 which are arranged on the outer circumference of the base body 121, are then swung out to the side in this case, so that they rest against the lines of the busbars come.
- mechanical locking elements are also swiveled out, which engage behind corresponding projections of the mounting rail profile, so that in addition to the electrical contacting, the luminaire 100 is also mechanically fastened to the mounting rail.
- the lever 125 project laterally to a certain extent in order to allow a comfortable actuation of the contacting element 120.
- the lateral slit 112 represents a permanent opening and thus a problem if the luminaire 100 is to be protected from the ingress of dust and/or moisture in order to meet the requirements of a so-called IP protection class.
- the present invention is therefore based on the object of offering an alternative possibility of reliably contacting the lines of a busbar positioned in a mounting rail profile, with the aim of avoiding the disadvantages mentioned above.
- connection contacts are now not arranged on a rotatable body, but are part of a linearly laterally adjustable contact block, which can be moved between an open position, in which the contacting element can be inserted and removed from the mounting rail profile, and a contacting position, in which the contact block can be connected to the connection contacts is extended laterally to contact the lines, is adjustable.
- a light or an electrical unit for a mounting rail which has a mounting rail profile with two side walls and at least one busbar, which is arranged on one of the two inner sides of the side walls of the mounting rail profile and has lines that can be electrically contacted, with the Luminaire or the electrical unit has a contacting element for electrical and, if necessary, mechanical connection to the mounting rail, and wherein the contacting element can be inserted into the mounting rail profile and has connection contacts, which are adjustable so that when the contacting element is in contact with lines when it is inserted into the mounting rail profile to get to the power rail.
- the contacting element has at least one linearly laterally adjustable contact block with at least one connection contact, which can be positioned between an open position, in which the contacting element can be inserted and removed from the mounting rail profile, and a contacting position, in which the contact block with the connection contact can be laterally contacted for contacting the Lines is extended, is adjustable.
- a contacting element for the electrical and mechanical connection of a lamp or an electrical unit to a mounting rail, which has a mounting rail profile with two side walls and at least one busbar, which is arranged on one of the two inner sides of the side walls of the mounting rail profile and has lines that can be electrically contacted , wherein the contacting element can be inserted into the mounting rail profile and has connecting contacts, which are adjustably mounted so that when the contacting element is inserted into the mounting rail profile, it comes into contact with lines of the busbar, and wherein, according to the invention, the contacting element has at least one linearly laterally adjustable contact block with at least has a connection contact, which can be adjusted between an open position, in which the contacting element can be inserted and removed from the support profile, and a contacting position, in which the contact block with the connection contact is extended laterally for contacting the lines.
- the contacting element is preferably made to have two contact blocks with connection contacts pointing in opposite directions, with both contact blocks being coupled in such a way that, starting from the open position, they can be transferred into the contacting position, moving away from one another.
- This configuration is particularly useful when corresponding conductor rails are arranged on both side walls of the mounting rail, as is the case, for example, with the "TECTON" system mentioned above.
- Both contact blocks can then move in opposite directions or towards one another in order to transfer the contacting element from a state in which it can be inserted into the mounting rail or removed from the mounting rail, into a state in which the lines of the busbars be contacted to carry out.
- Both contact blocks can advantageously interact with one another in order to use the linear movement according to the invention for contacting the lines.
- the two contact blocks are connected to one another via articulated arms that form a parallel guide.
- the two contact blocks are mounted pretensioned in the contacting position, with suitable pressing or actuating elements being arranged on the contacting element or a carrier element of the lamp or the electrical unit, which enable the contact blocks to be manually pressed together into the open position .
- the two contact blocks only have to be temporarily pressed together for inserting or removing the contacting element from the mounting rail. If, on the other hand, the pressure or actuating elements are relieved, the contact blocks automatically migrate to the side in order to contact the conductors of the busbars.
- another preferred embodiment of the invention provides that the contacting element is designed in such a way that a movement directed axially into the mounting rail profile is converted into a lateral movement of the two contact blocks.
- the two contact blocks are connected to one another via articulated arms that form a toggle joint.
- the toggle joint can be designed such that when pressure is exerted on the contact blocks in a direction opposite to the direction of insertion into the mounting rail profile, the contact blocks are transferred from the open position to the contacting position.
- the contact blocks When the contacting element is inserted into the mounting rail, the contact blocks automatically move laterally into the contacting position, which represents a particularly efficient and convenient configuration of the contacting element according to the invention.
- a solution that is comparable to the variant just described provides that the two contact blocks are mounted on a support of the lamp or the electrical unit by means of a wedge guide in such a way that when pressure is exerted on the contact blocks in a direction opposite to the direction of insertion into the mounting rail profile Contact blocks are pushed by a wedge arranged on the carrier from the open position to the contacting position. In this case, too, the insertion movement is automatically used to move the contact blocks laterally into the contacting position.
- the contact blocks are pretensioned in the open position, in particular are connected to one another accordingly via a tension spring.
- the contact blocks of the contacting element according to the invention can also have, in addition to the contacts for contacting the lines of the busbars, also outwardly pointing latching elements for mechanical attachment to the mounting rail profile.
- the effect can also be achieved in this case that, in addition to contacting the lines of the busbars, the luminaire or the electrical unit is also mechanically fastened to the mounting rail profile.
- At least one of the contacts of the contacting element according to the invention can be mounted on its contact block so that it can be adjusted in height. This opens up the possibility of making flexible contact with the various lines of the busbars, for example in order to assign a specific function to the consumer or the light.
- the light according to the invention is preferably an LED bar light.
- the design of the contacting element according to the invention opens up the possibility of continuously arranging LEDs as lighting means over the entire length of the lamp.
- an arrangement for light emission with a mounting rail which has a mounting rail profile with two side walls and at least one busbar, which is arranged on one of the two inner sides of the side walls of the mounting rail profile and has lines that can be electrically contacted, with a lamp or an electrical unit exists as described above.
- Busbars are preferably arranged on both sides of the mounting rail.
- the present invention is not limited to this special trunking system, but that the contacting elements according to the invention can always be used in principle whenever corresponding contacts of the contacting element have to be moved laterally to contact the lines of a mounting rail of a trunking system in order to connect the lines of a contact busbar.
- the support rail with the conductor rails arranged therein is therefore shown only schematically.
- connection to data lines used for communication would also be conceivable, whereby in particular the connection of sensors, cameras or similar components would be conceivable, which themselves transmit data via the lines of the light line system, which are then used, for example, for the automated control of the system.
- the present invention includes all conceivable electrical units that can be connected to a power rail in a meaningful way.
- the support rail 10 of the continuous-row system 1 has a downwardly open, U-shaped support rail profile 15 as a load-bearing element, which encloses an elongated receiving space 18 with two side walls 16 and a horizontal wall 17 connecting the side walls 16, into which the following is explained in more detail described contacting element is to be introduced.
- Busbars 20 with contactable lines 25 are arranged on both inner sides of the side walls 16, which can be contacted by the lights or other electrical units to be connected to the system 1.
- the storage of the lines 25 can be carried out by specially designed, consisting of an insulating material line support elements that form elongated grooves or channels open towards the inside, in which the lines 25, which are connected by uninsulated wires are formed, are stored.
- the configuration of the busbars 20 could also vary.
- the lines 25 are mounted in such a way that they are accessible from the interior 18 of the mounting rail 10 and can be contacted accordingly from this direction.
- the lines 25 do not necessarily have to cover the entire be accessible along the length of the system 1, but it would also be conceivable that contacting is only possible or provided in sections.
- the present figures show a so-called bar light 30 as the light to be connected to the system 1, which corresponds to the representation according to FIGS Figures 1a and 1b in the mounted state rests against the underside of the support rail profile 15 and has an elongate profile body 31 as a supporting element.
- the profile body 31 is also used here in particular for mounting the lamps, any components for the power supply of the lamps and any optical components which are present and which influence the light output of the lamp 30 in the desired manner.
- the design of these components is independent of the present invention, which is why these components are not shown in detail in the figures and are not to be explained in more detail below.
- the lamp 30 is designed to be mechanically fastened to the mounting rail 10 and to contact at least some of the lines 25 of the two busbars 20, which is made possible with the aid of the contacting elements according to the invention described in more detail below.
- the contacting elements are designed in such a way that they can be converted from a first configuration into a second configuration.
- the contacting element is designed in such a way that it can be inserted into the interior 18 of the mounting rail 10 and, in particular, does not collide with the bottom edges of the side walls 16 of the mounting rail profile 15 . In this state, there is also no contacting of the lines 25 of the busbars 20.
- the contacting element is in a state in which at least some of the lines 25 of the busbars 20 are contacted.
- mechanical latching or locking elements also engage behind corresponding projections on the mounting rail 10, so that mechanical attachment to the mounting rail 10 also takes place in addition to the electrical contacting.
- the contacting element is therefore also responsible for fastening the unit to be connected to the mounting rail 10 .
- the first exemplary embodiment of a contacting element according to the invention is provided with the reference number 40 .
- it has two so-called contact blocks 41 and 42, which are arranged on both sides of a longitudinal center plane E and carry contacts 43 pointing in opposite directions or respectively outwards.
- the number and the height positioning of the contacts 43 are only shown as examples in the figures and can, of course, also vary.
- the contact blocks 41, 42 are coupled to one another via a so-called toggle joint 45.
- This toggle joint 45 is formed by a first arm 46 which projects vertically upwards and is rigidly connected to the carrier 31 of the lamp 30 .
- the arm 46 is connected via a joint 47 to two pivoted arms 48, the end regions of which are in turn coupled in an articulated manner to one of the contact blocks 41 and 42, respectively.
- a tension spring 49 is provided, which connects the end regions of the two arms 48 to one another.
- the toggle joint 45 formed in this way now enables the two contact blocks 41 and 42 to be moved from the in Figure 1a illustrated position, which corresponds to an open position of the contacting element 40, in Figure 1b position shown can be transferred.
- the two contact blocks 41 and 42 are slightly extended laterally to the side in such a way that the outer ends of the contact tongues 43 now come into contact with the lines 25 of the busbars 20 .
- latching lugs 44 of the contact blocks 41, 42 engage behind latching projections provided at the lower end of the side walls 16 of the mounting rail 10.
- the lamp 30 is not only electrically connected to the lines 25 of the busbars 20, but is also fixed mechanically to the mounting rail 10.
- the position of the arms 48 in the contacting position of the contact blocks 41 and 42 shown is also such that the contact blocks 41 and 43 are locked by the tension spring 49 in the position shown.
- FIGS. 2a and 2b show a second exemplary embodiment of a contacting element according to the invention, which is now provided with the reference number 50 .
- This also offers the advantage that the two contact blocks 51, 52, which are equipped with corresponding contacts 53, come into contact with a stop 19 or the wall 17 when they are pushed into the receiving space 18 of the mounting rail 10 and then automatically migrate to the side. Again, the axial insertion movement is converted into a lateral movement of the contact blocks 51, 52.
- a guide element 55 used for this purpose is in turn firmly connected to the carrier 31 of the lamp 30 and forms two guide surfaces 56 that project upwards at an incline which in turn can slide over a tension spring 59 interconnected contact blocks 51, 52.
- the contact blocks 51, 52 have side walls facing the guide surfaces 56, which have a corresponding inclination, so that a change in the height of the contact blocks 51, 52 compared to the guide element 55 is converted into a lateral movement.
- the contact blocks 51, 52 then assume a position in which, on the one hand, the contacts 53 contact the lines 25 of the busbars and, on the other hand, latching projections 54 engage behind the support rail 10.
- latching projections or latching elements which are provided, for example, on the latching lugs 54 of the contact blocks 51, 52 and interact in a corresponding manner with the mounting rail profile 15, in the Figure 2a shown end position is secured.
- This latching or locking can then be overcome by suitably tightening the lamp 30 so that the lamp 30 can in turn be detached from the mounting rail 10 very easily in this way.
- FIGS Figures 3a and 3b A third exemplary embodiment of a contacting element 60 according to the invention is shown in FIGS Figures 3a and 3b shown.
- an axial movement is not automatically converted into a lateral movement of the two contact blocks 61,62.
- both contact blocks 61, 62 are connected to one another via a parallel guide 65.
- the guide 65 in Figure 3a is achieved by a cross into a slot-like recess 66 of a contact block 62 web 67 of the other contact block 61, while in the variant according to Figure 3b the parallel guide 65 is formed with the aid of two articulated arms 68 .
- both contact blocks 61, 62 are biased to an outward position.
- leaf springs 69 located in the space between the contact blocks 61, 62 ( Figure 3a ) and on the other hand a spiral spring 70 positioned in the lower area ( Figure 3b ). Both variants cause the contact blocks 61, 62 to be pretensioned in the outwardly directed contacting position.
- the two contact blocks 61, 62 In order to insert the contacting element 60 into the interior 18 of the mounting rail 10, it is therefore necessary for the two contact blocks 61, 62 to be temporarily moved towards one another against the spring force, which can be done manually by means of two laterally provided pressure fields 71, 72. If these pressure pads 71, 72 are relieved in the inserted state of the contacting element 70 in the interior 18 of the mounting rail 10, the contact blocks 61, 62 automatically move outwards again due to the spring force and in turn there is contact with the lines 25 of the busbars 20 and additionally also one mechanical locking with the mounting rail 10 via the locking elements 64.

Ein bekanntes Lichtbandsystem wird von der Anmelderin unter der Bezeichnung "TECTON" vertrieben und zeichnet sich dadurch aus, dass Leuchten oder andere elektrische Verbraucher flexibel über die gesamte Länge des Systems hinweg an der Tragschiene positioniert werden können. Ermöglicht wird dies dadurch, dass aufgrund einer speziellen Lagerung der Leitungen der Stromschiene diese über die im Wesentlichen gesamte Länge des Lichtbandsystems hinweg für die Verbraucher zugänglich sind, sodass ein Kontaktieren der Leitungen nicht nur an fest vorgegebenen Positionen, sondern an beliebiger Stelle erfolgen kann. Beispielsweise zeigt die
Bei dem oben angesprochenen System "TECTON" sind zwei Stromschienen einander gegenüberliegend an den beiden Seitenwänden eines nach unten offenen, U-förmigen Tragschienenprofils angeordnet. Das Kontaktieren der Leitungen der Stromschienen erfolgt dann dadurch, dass die Leuchte oder der Verbraucher ein drehbares Kontaktierungselement aufweist, welches von der Unterseite her in die Tragschiene eingeführt und anschließend um etwa 45° verdreht wird. An dem Kontaktierungselement angeordnete Kontakte sind hierbei derart ausgeführt, dass sie durch das Verdrehen seitlich ausgeschwenkt werden und letztendlich im verdrehten Zustand die Leitungen der Stromschienen kontaktieren.In the "TECTON" system mentioned above, two conductor rails are arranged opposite one another on the two side walls of a U-shaped carrier rail profile that is open at the bottom. The lines of the busbars are then contacted by the lamp or consumer having a rotatable contacting element, which is inserted into the mounting rail from the underside and then rotated by approximately 45°. Contacts arranged on the contacting element are designed in such a way that they are pivoted out to the side as a result of the twisting and ultimately contact the lines of the busbars in the twisted state.
Ursprünglich waren die oben beschriebenen drehbaren Kontaktierungselemente derart ausgeführt und an der Leuchte bzw. dem elektrischen Verbraucher gelagert, dass sie von der Unterseite der Leuchte her durch einen Benutzer betätigt, also verdreht werden konnten. Die Leuchte bzw. ein Trägerelement der Leuchte oder des Verbrauchers wurde dann also von der Unterseite her an die Tragschiene angesetzt, wobei dann in diesem an der Tragschiene anliegenden Zustand das oder die Kontaktierungselemente verdreht wurden. In diesem Fall mussten also die Kontaktierungselemente von der Unterseite der Leuchte oder des Verbrauchers her für eine Betätigung zugänglich sein, was üblicherweise kein Problem darstellte, da als Leuchtmittel in der Regel längliche Leuchtstofflampen zum Einsatz kamen, welche erst nach Befestigung der Leuchte an der Tragschiene in einfacher Weise durch den Verbraucher in die Fassungen der Leuchte eingesetzt werden konnten.Originally, the rotatable contacting elements described above were designed and mounted on the lamp or the electrical load in such a way that they could be actuated by a user from below the lamp, ie rotated. The lamp or a carrier element of the lamp or the consumer was then attached to the mounting rail from the underside, in which case the contacting element or elements was/were twisted in this state resting on the mounting rail. In this case, the contacting elements had to be accessible for actuation from the underside of the light or the consumer, which usually did not pose a problem, since elongated fluorescent lamps were usually used as the light sources, which were only switched on after the light was attached to the mounting rail could easily be used by the consumer in the sockets of the lamp.
Zwischenzeitlich kommen allerdings in der Beleuchtungstechnologie anstelle von Leuchtstofflampen überwiegend LEDs bzw. LED-Platinen als Leuchtmittel zum Einsatz, auch bei Leuchten, die zur Verwendung bei derartigen Tragschienen vorgesehen sind. Da das nachträgliche Anordnen von LED-Leuchtmitteln an einer Leuchte eher nicht sinnvoll bzw. möglich ist und ferner eine gleichmäßige Lichtabgabe nur dann erzielt werden kann, wenn die LEDs mehr oder weniger kontinuierlich über die gesamte Länge des Lichtbandsystems hinweg gleichmäßig verteilt angeordnet werden, ist es in der Regel nicht mehr möglich, die oben erläuterten drehbaren Kontaktierungselemente derart auszugestalten, dass sie von der Unterseite her zugänglich sind.In the meantime, however, instead of fluorescent lamps, LEDs or LED circuit boards are predominantly used as illuminants in lighting technology, even in the case of luminaires that are intended for use with such mounting rails. Since the subsequent arrangement of LED lamps on a luminaire is not sensible or possible and, moreover, a uniform light output can only be achieved if the LEDs are arranged more or less continuously and evenly distributed over the entire length of the light line system, it is usually no longer possible to design the rotatable contacting elements explained above in such a way that they are accessible from the underside.

Der vorliegenden Erfindung liegt deshalb die Aufgabenstellung zugrunde, eine alternative Möglichkeit anzubieten, die Leitungen einer in einem Tragschienenprofil positionierten Stromschiene zuverlässig zu kontaktieren, wobei die oben genannten Nachteile vermieden werden sollen.The present invention is therefore based on the object of offering an alternative possibility of reliably contacting the lines of a busbar positioned in a mounting rail profile, with the aim of avoiding the disadvantages mentioned above.
Die Aufgabe wird durch eine Leuchte oder eine elektrische Einheit mit den Merkmalen des Anspruchs 1 gelöst. Ferner wird die Aufgabe durch ein Kontaktierungselement mit den Merkmalen des Anspruchs 15 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a lamp or an electrical unit with the features of
Die erfindungsgemäße Lösung beruht auf dem Gedanken, die bislang bei den bekannten Kontaktierungselementen genutzte Rotationsbewegung durch linear seitlich verlaufende Bewegungen der Kontakte zu ersetzen. Die einzelnen Anschlusskontakte sind nunmehr also nicht an einem drehbaren Körper angeordnet, sondern Bestandteil eines linear seitlich verstellbaren Kontaktblocks, der zwischen einer Offenposition, in welcher ein Einführen und Entnehmen des Kontaktierungselements aus dem Tragschienenprofil ermöglicht ist, und einer Kontaktierungsposition, in welcher der Kontaktblock mit den Anschlusskontakten seitlich zum Kontaktieren der Leitungen ausgefahren ist, verstellbar ist. Wie nachfolgend anhand mehrerer Ausführungsbeispiele detailliert erläutert wird, kann in diesem Fall dann wiederum ein zuverlässiges und effizientes Kontaktieren der Leitungen der Stromschiene und darüber hinaus auch ein mechanisches Befestigen an der Tragschiene erzielt werden, wobei allerdings auf den im Stand der Technik genutzten Hebel bzw. generell auf Betätigungselemente, die durch Öffnungen oder Durchbrüche in der Leuchte seitlich herausragen, verzichtet werden kann. Damit können die oben beschriebenen Nachteile im Stand der Technik vermieden werden.The solution according to the invention is based on the idea of replacing the rotational movement previously used in the known contacting elements with linear lateral movements of the contacts. The individual connection contacts are now not arranged on a rotatable body, but are part of a linearly laterally adjustable contact block, which can be moved between an open position, in which the contacting element can be inserted and removed from the mounting rail profile, and a contacting position, in which the contact block can be connected to the connection contacts is extended laterally to contact the lines, is adjustable. As will be explained in detail below with reference to several exemplary embodiments, reliable and efficient contacting of the lines of the busbar and also mechanical attachment to the mounting rail can be achieved in this case, although this is based on the lever used in the prior art or in general there is no need for actuating elements that protrude laterally through openings or openings in the luminaire. The disadvantages of the prior art described above can thus be avoided.
Gemäß der vorliegenden Erfindung wird also eine Leuchte oder eine elektrische Einheit für eine Tragschiene, welche ein Tragschienenprofil mit zwei Seitenwänden sowie mindestens eine Stromschiene aufweist, welche an einer der beiden Innenseiten der Seitenwände des Tragschienenprofils angeordnet ist und elektrisch kontaktierbare Leitungen aufweist, vorgeschlagen, wobei die Leuchte oder die elektrische Einheit ein Kontaktierungselement zum elektrischen und ggf. mechanischen Anschließen an die Tragschiene aufweist, und wobei das Kontaktierungselement in das Tragschienenprofil einführbar ist und Anschlusskontakte aufweist, welche verstellbar sind, um in einem in das Tragschienenprofil eingesetzten Zustand des Kontaktierungselements in Anlage gegen Leitungen der Stromschiene zu gelangen. Erfindungsgemäß weist das Kontaktierungselement zumindest einen linear seitlich verstellbaren Kontaktblock mit mindestens einem Anschlusskontakt auf, der zwischen einer Offenposition, in welcher ein Einführen und Entnehmen des Kontaktierungselements aus dem Tragschienenprofil ermöglicht ist, und einer Kontaktierungsposition, in welcher der Kontaktblock mit dem Anschlusskontakt seitlich zum Kontaktieren der Leitungen ausgefahren ist, verstellbar ist.According to the present invention, a light or an electrical unit for a mounting rail is proposed, which has a mounting rail profile with two side walls and at least one busbar, which is arranged on one of the two inner sides of the side walls of the mounting rail profile and has lines that can be electrically contacted, with the Luminaire or the electrical unit has a contacting element for electrical and, if necessary, mechanical connection to the mounting rail, and wherein the contacting element can be inserted into the mounting rail profile and has connection contacts, which are adjustable so that when the contacting element is in contact with lines when it is inserted into the mounting rail profile to get to the power rail. According to the invention, the contacting element has at least one linearly laterally adjustable contact block with at least one connection contact, which can be positioned between an open position, in which the contacting element can be inserted and removed from the mounting rail profile, and a contacting position, in which the contact block with the connection contact can be laterally contacted for contacting the Lines is extended, is adjustable.
Ferner wird erfindungsgemäß ein Kontaktierungselement vorgeschlagen zum elektrischen und mechanischen Anschließen einer Leuchte oder einer elektrischen Einheit an eine Tragschiene, welche ein Tragschienenprofil mit zwei Seitenwänden sowie mindestens eine Stromschiene aufweist, welche an einer der beiden Innenseiten der Seitenwände des Tragschienenprofils angeordnet ist und elektrisch kontaktierbare Leitungen aufweist, wobei das Kontaktierungselement in das Tragschienenprofil einführbar ist und Anschlusskontakte aufweist, welche verstellbar gelagert sind, um in einem in das Tragschienenprofil eingesetzten Zustand des Kontaktierungselements in Anlage gegen Leitungen der Stromschiene zu gelangen, und wobei erfindungsgemäß das Kontaktierungselement zumindest einen linear seitlich verstellbaren Kontaktblock mit mindestens einem Anschlusskontakt aufweist, der zwischen einer Offenposition, in welcher ein Einführen und Entnehmen des Kontaktierungselements aus dem Tragprofil ermöglicht ist, und einer Kontaktierungsposition, in welcher der Kontaktblock mit dem Anschlusskontakt seitlich zum Kontaktieren der Leitungen ausgefahren ist, verstellbar ist.Furthermore, according to the invention, a contacting element is proposed for the electrical and mechanical connection of a lamp or an electrical unit to a mounting rail, which has a mounting rail profile with two side walls and at least one busbar, which is arranged on one of the two inner sides of the side walls of the mounting rail profile and has lines that can be electrically contacted , wherein the contacting element can be inserted into the mounting rail profile and has connecting contacts, which are adjustably mounted so that when the contacting element is inserted into the mounting rail profile, it comes into contact with lines of the busbar, and wherein, according to the invention, the contacting element has at least one linearly laterally adjustable contact block with at least has a connection contact, which can be adjusted between an open position, in which the contacting element can be inserted and removed from the support profile, and a contacting position, in which the contact block with the connection contact is extended laterally for contacting the lines.
Vorzugsweise ist vorgesehen, dass das Kontaktierungselement zwei Kontaktblöcke mit in entgegengesetzte Richtungen weisenden Anschlusskontakten aufweist, wobei beide Kontaktblöcke derart gekoppelt sind, dass sie ausgehend von der Offenposition sich voneinander entfernend in die Kontaktierungsposition überführt werden können. Diese Konfiguration bietet sich insbesondere dann an, wenn an beiden Seitenwänden der Tragschiene entsprechende Stromschienen angeordnet sind, wie dies bspw. bei dem oben erwähnten System "TECTON" der Fall ist. Beide Kontaktblöcke können sich dann in entgegengesetzte Richtungen bzw. aufeinander zu bewegen, um eine Überführung des Kontaktierungselements von einem Zustand, in dem ein Einführen in die Tragschiene bzw. ein Entnehmen aus der Tragschiene möglich ist, in einen Zustand, in dem die Leitungen der Stromschienen kontaktiert werden, durchzuführen. Beide Kontaktblöcke können dabei in vorteilhafter Weise miteinander zusammenwirken, um die erfindungsgemäße Linearbewegung zum Kontaktieren der Leitungen zu nutzen.Provision is preferably made for the contacting element to have two contact blocks with connection contacts pointing in opposite directions, with both contact blocks being coupled in such a way that, starting from the open position, they can be transferred into the contacting position, moving away from one another. This configuration is particularly useful when corresponding conductor rails are arranged on both side walls of the mounting rail, as is the case, for example, with the "TECTON" system mentioned above. Both contact blocks can then move in opposite directions or towards one another in order to transfer the contacting element from a state in which it can be inserted into the mounting rail or removed from the mounting rail, into a state in which the lines of the busbars be contacted to carry out. Both contact blocks can advantageously interact with one another in order to use the linear movement according to the invention for contacting the lines.
Dabei ist bei einem ersten Ausführungsbeispiel der Erfindung vorgesehen, dass beide Kontaktblöcke über Gelenkarme, die eine Parallelführung bilden, miteinander verbunden sind. Insbesondere kann hierbei dann vorgesehen sein, dass die beiden Kontaktblöcke in die Kontaktierungsposition vorgespannt gelagert sind, wobei an dem Kontaktierungselement oder einem Trägerelement der Leuchte oder der elektrischen Einheit geeignete Drück- bzw. Betätigungselemente angeordnet sind, welche ein manuelles Zusammendrücken der Kontaktblöcke in die Offenposition ermöglichen. Lediglich für das Einführen bzw. Entnehmen des Kontaktierungselements aus der Tragschiene müssen also beide Kontaktblöcke vorübergehend zusammengedrückt werden. Werden hingegen die Drück- bzw. Betätigungselemente entlastet, so wandern automatisch die Kontaktblöcke seitlich aus, um die Leitungen der Stromschienen zu kontaktieren.In a first exemplary embodiment of the invention, it is provided that the two contact blocks are connected to one another via articulated arms that form a parallel guide. In particular, it can then be provided that the two contact blocks are mounted pretensioned in the contacting position, with suitable pressing or actuating elements being arranged on the contacting element or a carrier element of the lamp or the electrical unit, which enable the contact blocks to be manually pressed together into the open position . The two contact blocks only have to be temporarily pressed together for inserting or removing the contacting element from the mounting rail. If, on the other hand, the pressure or actuating elements are relieved, the contact blocks automatically migrate to the side in order to contact the conductors of the busbars.
Eine andere bevorzugte Ausführungsform der Erfindung sieht hingegen vor, dass das Kontaktierungselement derart ausgebildet ist, dass eine axial in das Tragschienenprofil gerichtete Bewegung in eine seitliche Bewegung der beiden Kontaktblöcke umgesetzt wird.In contrast, another preferred embodiment of the invention provides that the contacting element is designed in such a way that a movement directed axially into the mounting rail profile is converted into a lateral movement of the two contact blocks.
Gemäß einer ersten Variante kann hierbei vorgesehen sein, dass die beiden Kontaktblöcke über Gelenkarme, die ein Kniehebelgelenk bilden, miteinander verbunden sind. Insbesondere kann hierbei das Kniehebelgelenk derart ausgeführt sein, dass bei Druckausübung auf die Kontaktblöcke in einer Richtung entgegengesetzt zur Richtung des Einführens in das Tragschienenprofil die Kontaktblöcke von der Offenposition in die Kontaktierungsposition überführt werden. Beim Einsetzen des Kontaktierungselements in die Tragschiene wandern also die Kontaktblöcke automatisch seitlich in die Kontaktierungsposition aus, was eine besonders effiziente und komfortable Ausgestaltung des erfindungsgemäßen Kontaktierungselements darstellt.According to a first variant, it can be provided that the two contact blocks are connected to one another via articulated arms that form a toggle joint. In particular, the toggle joint can be designed such that when pressure is exerted on the contact blocks in a direction opposite to the direction of insertion into the mounting rail profile, the contact blocks are transferred from the open position to the contacting position. When the contacting element is inserted into the mounting rail, the contact blocks automatically move laterally into the contacting position, which represents a particularly efficient and convenient configuration of the contacting element according to the invention.
Eine zu der soeben beschriebenen Variante vergleichbare Lösung sieht hingegen vor, dass die beiden Kontaktblöcke mittels einer Keilführung derart an einem Träger der Leuchte oder der elektrischen Einheit gelagert sind, dass bei Druckausübung auf die Kontaktblöcke in einer Richtung entgegengesetzt zur Richtung des Einführens in das Tragschienenprofil die Kontaktblöcke durch einen an dem Träger angeordneten Keil von der Offenposition in die Kontaktierungsposition gedrängt werden. Auch in diesem Fall wird also die Einführbewegung automatisch dazu genutzt, die Kontaktblöcke seitlich in die Kontaktierungsposition zu verschieben.On the other hand, a solution that is comparable to the variant just described provides that the two contact blocks are mounted on a support of the lamp or the electrical unit by means of a wedge guide in such a way that when pressure is exerted on the contact blocks in a direction opposite to the direction of insertion into the mounting rail profile Contact blocks are pushed by a wedge arranged on the carrier from the open position to the contacting position. In this case, too, the insertion movement is automatically used to move the contact blocks laterally into the contacting position.
Bei beiden soeben beschriebenen Varianten kann dabei vorgesehen sein, dass die Kontaktblöcke in die Offenposition vorgespannt sind, insbesondere über eine Zugfeder entsprechend miteinander verbunden sind.In both of the variants just described, it can be provided that the contact blocks are pretensioned in the open position, in particular are connected to one another accordingly via a tension spring.
Die Kontaktblöcke des erfindungsgemäßen Kontaktierungselements können ferner neben den Kontakten zum Kontaktieren der Leitungen der Stromschienen auch nach außen weisende Rastelemente zum mechanischen Befestigen an dem Tragschienenprofil aufweisen. In gleicher Weise wie im Stand der Technik kann auch in diesem Fall der Effekt erzielt werden, dass neben einem Kontaktieren der Leitungen der Stromschienen gleichzeitig auch ein mechanisches Befestigen der Leuchte oder der elektrischen Einheit an dem Tragschienenprofil erfolgt.The contact blocks of the contacting element according to the invention can also have, in addition to the contacts for contacting the lines of the busbars, also outwardly pointing latching elements for mechanical attachment to the mounting rail profile. In the same way as in the prior art, the effect can also be achieved in this case that, in addition to contacting the lines of the busbars, the luminaire or the electrical unit is also mechanically fastened to the mounting rail profile.
Zumindest einer der Kontakte des erfindungsgemäßen Kontaktierungselements kann hierbei höhenverstellbar an seinem Kontaktblock gelagert sein. Dies eröffnet die Möglichkeit, die verschiedenen Leitungen der Stromschienen flexibel zu kontaktieren, um bspw. dem Verbraucher bzw. der Leuchte gezielt eine bestimmte Funktion zuzuweisen.At least one of the contacts of the contacting element according to the invention can be mounted on its contact block so that it can be adjusted in height. This opens up the possibility of making flexible contact with the various lines of the busbars, for example in order to assign a specific function to the consumer or the light.
Vorzugsweise handelt es sich bei der erfindungsgemäßen Leuchte um eine LED-Balkenleuchte. Die erfindungsgemäße Ausgestaltung des Kontaktierungselements eröffnet hierbei die Möglichkeit, über die gesamte Länge der Leuchte hinweg kontinuierlich LEDs als Leuchtmittel anzuordnen.The light according to the invention is preferably an LED bar light. The design of the contacting element according to the invention opens up the possibility of continuously arranging LEDs as lighting means over the entire length of the lamp.
Erfindungsgemäß wird ferner eine Anordnung zur Lichtabgabe mit einer Tragschiene vorgeschlagen, welche ein Tragschienenprofil mit zwei Seitenwänden sowie mindestens eine Stromschiene aufweist, welche an einer der beiden Innenseiten der Seitenwände des Tragschienenprofils angeordnet ist und elektrisch kontaktierbare Leitungen aufweist, wobei ferner eine Leuchte oder eine elektrische Einheit wie oben beschrieben vorhanden ist. Vorzugsweise sind an beiden Seiten der Tragschiene Stromschienen angeordnet.According to the invention, an arrangement for light emission with a mounting rail is also proposed, which has a mounting rail profile with two side walls and at least one busbar, which is arranged on one of the two inner sides of the side walls of the mounting rail profile and has lines that can be electrically contacted, with a lamp or an electrical unit exists as described above. Busbars are preferably arranged on both sides of the mounting rail.

Bei der nachfolgenden detaillierten Erläuterung der erfindungsgemäßen Ausführungsbeispiele wird von einem Lichtbandsystem ausgegangen, welches hinsichtlich seiner Ausgestaltung im Wesentlichen dem bereits oben erwähnten, von der Anmelderin vertriebenen Lichtbandsystem "TECTON" entspricht. Eine Besonderheit dieses Systems besteht darin, dass die hier entlang der Tragschiene verlaufenden Leitungen zur Stromversorgung der Leuchten oder Verbraucher derart gelagert sind, dass sie über die gesamte Länge des Lichtbandsystems hinweg durchgängig kontaktierbar sind, sodass Leuchten oder andere Verbraucher flexibel über die gesamte Länge des Lichtbandsystems hinweg angeordnet werden können. Allerdings ist darauf hinzuweisen, dass die vorliegende Erfindung nicht auf dieses spezielle Lichtbandsystem beschränkt ist, sondern die erfindungsgemäßen Kontaktierungselemente grundsätzlich immer dann verwendet werden können, wenn zum Kontaktieren der Leitungen einer Tragschiene eines Lichtbandsystems entsprechende Kontakte des Kontaktierungselements seitlich bewegt werden müssen, um die Leitungen einer Stromschiene zu kontaktieren. In den nachfolgend näher erläuterten Figuren ist deshalb die Tragschiene mit den darin angeordneten Stromschienen lediglich schematisch dargestellt.The following detailed explanation of the exemplary embodiments according to the invention is based on a continuous-row system which, in terms of its configuration, essentially corresponds to the “TECTON” continuous-row system already mentioned above and sold by the applicant. A special feature of this system is that the cables running along the mounting rail for the power supply of the lights or consumers are mounted in such a way that they can be continuously contacted over the entire length of the light line system, so that lights or other consumers can be flexibly connected can be arranged over the entire length of the light line system. However, it should be pointed out that the present invention is not limited to this special trunking system, but that the contacting elements according to the invention can always be used in principle whenever corresponding contacts of the contacting element have to be moved laterally to contact the lines of a mounting rail of a trunking system in order to connect the lines of a contact busbar. In the figures explained in more detail below, the support rail with the conductor rails arranged therein is therefore shown only schematically.
Ferner ist darauf hinzuweisen, dass ein Kontaktieren der Leitungen einer Stromschiene nicht unbedingt dazu dienen muss, die anzuschließende Einheit mit Strom zu versorgen. Auch der Anschluss an zur Kommunikation genutzte Datenleitungen wäre denkbar, wobei insbesondere auch das Anschließen von Sensoren, Kameras oder ähnlichen Komponenten denkbar wäre, die von sich aus Daten über die Leitungen des Lichtbandsystems übermitteln, welche dann z.B. zur automatisieren Steuerung des Systems genutzt werden. Im diesen Sinn umfasst die vorliegende Erfindung sämtliche denkbaren elektrischen Einheiten, die in sinnvoller Weise an eine Stromschiene angeschlossen werden können.It should also be pointed out that contacting the lines of a power rail does not necessarily have to be used to supply the unit to be connected with power. The connection to data lines used for communication would also be conceivable, whereby in particular the connection of sensors, cameras or similar components would be conceivable, which themselves transmit data via the lines of the light line system, which are then used, for example, for the automated control of the system. In this sense, the present invention includes all conceivable electrical units that can be connected to a power rail in a meaningful way.
Entsprechend den Darstellungen weist also die Tragschiene 10 des Lichtbandsystems 1 als tragendes Element ein nach unten offenes, U-förmiges Tragschienenprofil 15 auf, welches mit zwei Seitenwänden 16 sowie einer die Seitenwände 16 verbindenden Horizontalwand 17 einen länglichen Aufnahmeraum 18 umschließt, in den das nachfolgend näher beschriebene Kontaktierungselement einzuführen ist. An beiden Innenseiten der Seitenwände 16 sind Stromschienen 20 mit kontaktierbaren Leitungen 25 angeordnet, die durch die an das System 1 anzuschließenden Leuchten oder anderen elektrischen Einheiten kontaktierbar sind. Wie bereits aus dem Stand der Technik bekannt, kann hierbei die Lagerung der Leitungen 25 durch speziell ausgebildete, aus einem isolierenden Material bestehende Leitungshalterungselemente erfolgen, die zur Innenseite hin offene längliche Nuten bzw. Kanäle bilden, in denen die Leitungen 25, welche durch unisolierte Drähte gebildet werden, gelagert sind. Grundsätzlich könnte die Ausgestaltung der Stromschienen 20 auch variieren. Wesentlich ist allerdings, dass die Leitungen 25 derart gelagert sind, dass sie vom Innenraum 18 der Tragschiene 10 aus zugänglich sind und von dieser Richtung aus entsprechend kontaktiert werden können. Die Leitungen 25 müssen hierbei allerdings nicht zwingend über die gesamte Länge des Systems 1 hinweg zugänglich sein, sondern es wäre auch denkbar, dass lediglich abschnittsweise eine Kontaktierung möglich bzw. vorgesehen ist.According to the illustrations, the
Als an das System 1 anzuschließende Leuchte ist in den vorliegenden Figuren eine sog. Balkenleuchte 30 gezeigt, welche entsprechend der Darstellung gemäß den
Entscheidend ist, dass die Leuchte 30 dazu ausgebildet ist, an der Tragschiene 10 mechanisch befestigt zu werden und zumindest einige der Leitungen 25 der beiden Stromschienen 20 zu kontaktieren, was mit Hilfe der nachfolgend näher beschriebenen erfindungsgemäßen Kontaktierungselemente ermöglicht wird.The decisive factor is that the
Grundsätzlich sind die Kontaktierungselemente derart ausgeführt, dass sie von einer ersten Konfiguration in eine zweite Konfiguration überführt werden können.In principle, the contacting elements are designed in such a way that they can be converted from a first configuration into a second configuration.
In der ersten Konfiguration ist das Kontaktierungselement derart ausgestaltet, dass es in den Innenraum 18 der Tragschiene 10 eingeführt werden kann und hierbei insbesondere nicht mit den Unterkanten der Seitenwände 16 des Tragschienenprofils 15 kollidiert. In diesem Zustand erfolgt ferner auch noch keine Kontaktierung der Leitungen 25 der Stromschienen 20.In the first configuration, the contacting element is designed in such a way that it can be inserted into the interior 18 of the mounting
In der zweiten Konfiguration hingegen befindet sich das Kontaktierungselement in einem Zustand, in dem zumindest einige der Leitungen 25 der Stromschienen 20 kontaktiert werden. Idealerweise hintergreifen mechanische Rast- oder Verriegelungselemente zusätzlich auch noch entsprechende Vorsprünge an der Tragschiene 10, sodass zusätzlich zur elektrischen Kontaktierung auch eine mechanische Befestigung an der Tragschiene 10 erfolgt. Das Kontaktierungselement ist somit zusätzlich auch für eine Befestigung der anzuschließenden Einheit an der Tragschiene 10 verantwortlich.In the second configuration, on the other hand, the contacting element is in a state in which at least some of the

Damit die z.B. als Kontaktzungen ausgebildeten Kontakte 43 die Leitungen 25 kontaktieren können, muss die Möglichkeit bestehen, diese Kontakte 43 seitlich auszufahren. Ermöglicht wird dies bei dem ersten erfindungsgemäßen Ausführungsbeispiel dadurch, dass die Kontaktblöcke 41, 42 über ein sog. Kniehebelgelenk 45 miteinander gekoppelt sind. Dieses Kniehebelgelenk 45 wird durch einen vertikal nach oben ragenden ersten Arm 46 gebildet, der starr mit dem Träger 31 der Leuchte 30 verbunden ist. An seinem oberen Ende ist der Arm 46 über ein Gelenk 47 mit zwei schwenkbar gelagerten Armen 48 verbunden, deren Endbereiche jeweils wiederum gelenkig mit einem der Kontaktblöcke 41 bzw. 42 gekoppelt sind. Weiterhin ist eine Zugfeder 49 vorgesehen, welche die Endbereiche der beiden Arme 48 miteinander verbindet.In order for the

Ermöglicht wird dies im zweiten Ausführungsbeispiel durch eine Keilführung für die beiden Kontaktblöcke 51 und 52. Ein hierzu verwendetes, im Schnitt etwa kegelstumpfartig ausgebildetes Führungselement 55 ist wiederum fest mit dem Träger 31 der Leuchte 30 verbunden und bildet zwei geneigt nach oben ragende Führungsflächen 56, entlang denen die wiederum über eine Zugfeder 59 miteinander verbundenen Kontaktblöcke 51, 52 gleiten können. Die Kontaktblöcke 51, 52 weisen hierbei den Führungsflächen 56 zugewandte Seitenwände auf, die eine entsprechende Neigung aufweisen, sodass eine Veränderung der Höhe der Kontaktblöcke 51, 52 im Vergleich zum Führungselement 55 in eine seitliche Bewegung umgesetzt wird.In the second exemplary embodiment, this is made possible by a wedge guide for the two

Wiederum nehmen die Kontaktblöcke 51, 52 in diesem Fall dann eine Stellung ein, in der einerseits die Kontakte 53 die Leitungen 25 der Stromschienen kontaktieren und andererseits Rastvorsprünge 54 die Tragschiene 10 hintergreifen. Dabei kann vorgesehen sein, dass mittels spezieller - nicht dargestellter - Rastvorsprünge oder Rastelemente, die bspw. an den Rastnasen 54 der Kontaktblöcke 51, 52 vorgesehen sind und in entsprechender Weise mit dem Tragschienenprofil 15 zusammenwirken, die in

Werden diese Drückfelder 71, 72 im eingesetzten Zustand des Kontaktierungselements 70 in dem Innenraum 18 der Tragschiene 10 entlastet, so wandern die Kontaktblöcke 61, 62 automatisch durch die Federkraft wieder nach außen und wiederum erfolgt ein Kontaktieren der Leitungen 25 der Stromschienen 20 sowie zusätzlich auch eine mechanische Verriegelung mit der Tragschiene 10 über die Rastelemente 64.In order to insert the contacting
Alle drei beschriebenen Varianten zeichnen sich also dadurch aus, dass in einfacher aber effizienter Weise ein Kontaktieren von Stromschienen einerseits sowie ein mechanisches Befestigen von Verbrauchern an Tragschienen andererseits ermöglicht wird. Dadurch allerdings, dass nunmehr kein Verdrehen bzw. Verschwenken eines Kontaktierungselements erforderlich ist, können die oben beschriebenen Nachteile im Stand der Technik vermieden werden.All three variants described are characterized in that, on the one hand, contacting busbars and, on the other hand, mechanical attachment of consumers to mounting rails is made possible in a simple but efficient manner. However, the fact that now no twisting or pivoting of a Contacting element is required, the disadvantages described above in the prior art can be avoided.
