Since the connection system provides a rotation of the mounting rail of maximum 360 °, the flexibility of a conventional Cable sufficient to follow this movement.
- the passage opening is aligned along the axis of rotation of the bearing parts.
- the mechanical forces acting on the wiring are lowest at this point.

Description
Die Erfindung betrifft ein Verbindungssystem für Tragschienen von Leuchteneinsätzen, wie sie zur Ausbildung von Lichtbändern eingesetzt werden. Mehrere Tragschienen lassen sich hintereinander durch das Verbindungssystem verbinden und sind dennoch beweglich gegeneinander.The invention relates to a connection system for mounting rails of lamp inserts, as they are used to form light bands. Several mounting rails can be connected in series through the connection system and are still movable against each other.
Lichtbänder werden üblicherweise aus einer Vielzahl von länglichen Leuchten oder Leuchteinsätzen zusammengesetzt, die stirnseitig aneinander angrenzend montiert werden. Um ein Ausrichten der Leuchten an den Stirnseiten zu ermöglichen, ist es im Stand der Technik üblich, die Leuchten fest miteinander zu verbinden. Zu diesem Zweck sind Verbindungssysteme bekannt.Light bands are usually composed of a variety of elongated lights or lighting inserts, which are mounted frontally adjacent to each other. In order to enable alignment of the lights on the end faces, it is common in the art to connect the lights firmly together. For this purpose connection systems are known.
Leuchten, die sich zu einem Lichtband miteinander verbinden lassen, sind beispielsweise aus der
Ein Nachteil des eingangs genannten Systems besteht jedoch darin, daß zum Verschwenken der Leuchte die Schraubverbindung wenigstens teilweise gelöst werden muß. Ferner besteht beim Verschwenken einzelner Leuchten die Gefahr, daß eine Durchgangsverdrahtung, die von einer zur nächsten Leuchte führt, beim Verschwenken beschädigt wird.A disadvantage of the aforementioned system, however, is that for pivoting the lamp, the screw must be at least partially solved. Furthermore, when pivoting individual lights there is a risk that a through-wiring, which leads from one to the next light, is damaged during pivoting.
Weitere Mechanismen zum schwenkbaren Montieren von Leuchten sind beispielsweise aus der
Es besteht daher ein Bedarf an einem Verbindungssystem für Leuchten eines Lichtbandsystems, insbesondere für Tragschienen eines solchen Lichtbandsystems, das ein Verstellen der Leuchten um ihre Längsachse ermöglicht und dennoch einfach zu handhaben ist und in bezug auf die elektrische Verdrahtung eine hohe Betriebssicherheit gewährleistet.There is therefore a need for a connection system for luminaires of a lighting system, in particular for mounting rails of such a lighting system that allows adjustment of the lights around its longitudinal axis and yet easy to handle and with respect to the electrical wiring ensures high reliability.
Die Erfindung wird gelöst durch ein Verbindungssystem nach Anspruch 1 bzw. durch ein Lichtbandsystem nach Anspruch 17.The invention is achieved by a connection system according to claim 1 or by a lighting system according to claim 17.
Das Verbindungssystem für Tragschienen eines Lichtbandsystems oder für Leuchten umfaßt folgendes: Zwei Verbinder, die jeweils zum Anbringen an einen stirnseitigen Abschnitt einer Tragschiene eingerichtet sind, eine bewegliche Kupplung, die zwischen den zwei Verbindern angebracht ist, wobei die Kupplung an zwei Seiten an jeweils einem Verbinder starr angebracht ist, wobei die Kupplung eine Durchgangsöffnung aufweist, durch die eine Durchgangsverdrahtung zwischen den angrenzenden Tragschienen hindurchführbar ist.The trunking system or lighting system trunking system includes: two connectors each adapted for attachment to an end portion of a support rail, a movable coupling mounted between the two connectors, the coupling being attached to two sides on a respective one connector is rigidly mounted, wherein the coupling has a passage opening through which a through-wiring between the adjacent support rails can be passed.
Insbesondere weist die Kupplung wenigstens ein erstes und ein zweites Lagerteil auf, die drehbar ineinandergreifen und jedes der Lagerteile ist an jeweils einen Verbinder starr angebracht.In particular, the coupling has at least a first and a second bearing part, which engage in a rotatable manner, and each of the bearing parts is rigidly attached to a respective connector.
Die bewegliche Kupplung der vorliegenden Erfindung stellt die Möglichkeit zur Verfügung, die Leuchte in der Längsachse zu drehen. Insbesondere kann die Kupplung so ausgebildet sein, daß eine Drehung der Leuchte um bis zu 360° möglich ist. Durch das Anordnen der Durchgangsverdrahtung in einer Durchgangsöffnung der Kupplung ist ein Drehen der Tragschiene um die Längsachse möglich, ohne die Gefahr einer Beschädigung der Durchgangsverdrahtung, insbesondere durch Abscheren. Üblicherweise werden zur Verdrahtung der Lichtbandsysteme Kabelbündel oder Flachbandkabel benutzt, die mehrfach in sich gedreht werden können, ohne daß die Gefahr eines Kabelbruchs besteht. Da das Verbindungssystem ein Drehen der Tragschiene von maximal 360° vorsieht, ist die Flexibilität eines herkömmlichen Kabels ausreichend, um dieser Bewegung folgen zu können. Durch die Anordnung der Durchgangsverdrahtung in einer Durchgangsöffnung der Kupplung besteht keine Gefahr, daß das Kabel an irgendeiner Stelle der beweglichen Teile beschädigt wird.The movable coupling of the present invention provides the ability to rotate the luminaire in the longitudinal axis. In particular, the coupling can be designed so that a rotation of the lamp by up to 360 ° is possible. By arranging the through-wiring in a through-opening of the coupling, a rotation of the support rail about the longitudinal axis is possible, without the risk of damage to the through-wiring, in particular by shearing. Usually, cable harnesses or ribbon cables are used for wiring the trunking systems, which can be rotated several times without the risk of cable breakage. Since the connection system provides a rotation of the mounting rail of maximum 360 °, the flexibility of a conventional Cable sufficient to follow this movement. By arranging the through-wiring in a through-hole of the coupling, there is no danger that the cable will be damaged anywhere in the moving parts.
Vorzugsweise ist die Durchgangsöffnung entlang der Drehachse der Lagerteile ausgerichtet. Die mechanischen Kräfte, die auf die Verdrahtung wirken, sind an dieser Stelle am geringsten.Preferably, the passage opening is aligned along the axis of rotation of the bearing parts. The mechanical forces acting on the wiring are lowest at this point.
Gemäß einer bevorzugten Ausführungsform weist das erste Lagerteil einen röhrenförmigen Abschnitt auf, der sich in eine zylindrische Öffnung des zweiten Lagerteils erstreckt. Insbesondere kann sich der röhrenförmige Abschnitt des ersten Lagerteils bis über die zylindrische Öffnung des zweiten Lagerteils erstrecken und an dem Abschnitt, der aus der zylindrischen Öffnung des zweiten Lagerteils herausragt, gesichert sein. Beispielsweise kann in dem überstehenden Abschnitt eine Nut vorgesehen sein, auf die ein Sprengring aufgeschoben ist. Die Lagerteile sind bei der bevorzugten Ausführungsform frei gegeneinander drehbar, werden jedoch in axialer Richtung aneinander gesichert.According to a preferred embodiment, the first bearing part has a tubular portion which extends into a cylindrical opening of the second bearing part. In particular, the tubular portion of the first bearing member may extend beyond the cylindrical opening of the second bearing member and be secured to the portion protruding from the cylindrical opening of the second bearing member. For example, may be provided in the protruding portion, a groove on which a snap ring is pushed. The bearing parts are freely rotatable against each other in the preferred embodiment, but are secured together in the axial direction.
Gemäß einer bevorzugten Ausführungsform ist die Kupplung bzw. das erste und das zweite Lagerteil gegeneinander blockierbar. Insbesondere kann ein Blockieren durch eine formschlüssige, eine reibschlüssige oder eine kraftschlüssige Verbindung vorgesehen sein. Das Blockieren der Lagerteile ermöglicht das Feststellen der Tragschienen in dem Lichtband. Dadurch läßt sich ein unbeabsichtigtes Verstellen der einmal eingestellten Leuchten verhindern, wie es beispielsweise bei Reinigungsarbeiten oder Wartungsarbeiten auftreten könnte. Ferner lassen sich durch die Möglichkeit der Blockierung des drehbaren Lagers auch Leuchten in eine beliebige Drehlage bringen, deren Schwerpunkt außerhalb der Drehachse ein selbständiges Zurückschwenken bewirken würde.According to a preferred embodiment, the coupling or the first and the second bearing part can be locked against each other. In particular, blocking may be provided by a positive, a frictional or a frictional connection. The blocking of the bearing parts allows the fixing of the mounting rails in the light band. This can prevent inadvertent adjustment of the lights once set, as might occur, for example, during cleaning or maintenance. Furthermore, by the possibility of blocking the rotatable bearing and lamps bring in any rotational position, the focus would cause an independent pivoting back outside the axis of rotation.
Insbesondere kann eines der Lagerteile eine Arretiereinrichtung aufweisen, die in einem arretierten Zustand der Kupplung auf das andere Lagerteil formschlüssig oder reibschlüssig einwirkt, um die Drehung zu blockieren oder wenigstens zu hemmen. Die Arretiereinrichtung kann eine Schraube umfassen, die direkt oder indirekt eine Kraft auf das andere Lagerteil aufbringt, um die Kupplung reibschlüssig oder kraftschlüssig zu blockieren.In particular, one of the bearing parts may have a locking device, which acts in a locked state of the coupling to the other bearing part positively or frictionally engaged to block the rotation or at least inhibit. The locking device may comprise a screw which directly or indirectly applies a force to the other bearing part in order to block the coupling frictionally or non-positively.
Vorzugsweise ist die Schraubenachse der Arretierschraube senkrecht zur Drehachse der Kupplung angeordnet. In dieser Position ist die Arretierschraube gut zugänglich, um von einem Monteur zum Verstellen der Leuchte geöffnet oder geschlossen zu werden. Insbesondere ist die Arretierschraube beispielsweise eine Madenschraube, die in einer Querbohrung eines der Lagerteile vorgesehen ist und auf dem Umfang des zweiten Lagerteils im eingeschraubten Zustand eine Kraft auswirkt.Preferably, the screw axis of the locking screw is arranged perpendicular to the axis of rotation of the coupling. In this position, the locking screw is easily accessible to be opened or closed by a fitter for adjusting the lamp. In particular, the locking screw, for example, a grub screw which is provided in a transverse bore of one of the bearing parts and on the circumference of the second bearing part in the screwed-in state, a force acts.
Gemäß einer alternativen Ausführungsform umfaßt die Arretiervorrichtung ein federbelastendes Element, beispielsweise eine federbelastende Kugel oder einen Stift, das unter einer Vorspannung auf eines der Lagerteile einwirkt, um die Kupplung reibschlüssig oder formschlüssig zu blockieren.According to an alternative embodiment, the locking device comprises a spring-loaded element, for example a spring-loaded ball or a pin, which acts under a bias on one of the bearing parts to frictionally or positively lock the coupling.
Gemäß einer bevorzugten Ausführungsform des Verbindungssystems mit Arretiereinrichtung sind auf einem der Lagerteile Rastvertiefungen vorgesehen, um mit der Arretiereinrichtung auf dem anderen Lagerteil zusammenzuwirken. Die Rastvertiefungen können beispielsweise runde Vertiefungen sein, in die das Ende der Arretierschraube formschlüssig eingreift. Bei einer Arretiervorrichtung in Form eines federbelastenden Elements kann beispielsweise eine Kugel durch eine Feder in die Vertiefung gedrückt werden. Letzteres hat den Vorteil, daß die Arretiereinrichtung zum Drehen der Tragschiene nicht von Hand gelöst werden muß, sondern nur ein mechanischer Widerstand überwunden werden muß, der durch die Stärke der Vorspannung, die auf das federbelastende Element wirkt, definiert ist. Für besonders schwere Leuchten oder Leuchten, die nur selten verstellt werden sollen, hat die Ausführungsform der Arretiereinrichtung mit einer Schraube den Vorteil, daß die Verstellmöglichkeit vollständig blockiert ist, so daß ein unbeabsichtigtes oder selbständiges Verstellen der Tragschiene ausgeschlossen ist.According to a preferred embodiment of the connection system with locking means locking recesses are provided on one of the bearing parts to cooperate with the locking device on the other bearing part. The detent recesses may be, for example, round depressions into which the end of the locking screw engages positively. In a locking device in the form of a spring-loaded element, for example, a ball can be pressed by a spring in the recess. The latter has the advantage that the locking device for rotating the support rail does not have to be released by hand, but only a mechanical resistance must be overcome, which is defined by the strength of the bias acting on the spring-loaded element. For particularly heavy lights or lights that are rarely adjusted, the embodiment of the Locking device with a screw has the advantage that the adjustment is completely blocked, so that an unintentional or independent adjustment of the support rail is excluded.
Gemäß einer bevorzugten Ausführungsform ist zwischen dem ersten Lagerteil und dem zweiten Lagerteil eine Buchse angeordnet. Die Buchse kann ein gehärtetes Material aufweisen, so daß der Verschleiß der Lagerflächen bei häufiger Bewegung reduziert wird.According to a preferred embodiment, a bush is arranged between the first bearing part and the second bearing part. The bush may comprise a hardened material so that the wear of the bearing surfaces is reduced with frequent movement.
In der Durchgangsöffnung der Kupplung ist gemäß einer bevorzugten Ausführungsform der Erfindung ein Schlauch, insbesondere aus einem elastischen Material, vorgesehen. Dieser Schlauch dient zum Schützen der durch die Durchgangsöffnung hindurchgeführten Durchgangsverdrahtung.In the passage opening of the coupling according to a preferred embodiment of the invention, a hose, in particular made of an elastic material, is provided. This tube serves to protect the through-wiring passed through the through-hole.
Gemäß einer Ausführungsform der Erfindung ist zwischen einem oder beiden der Lagerteile und dem jeweils daran angebrachten Verbinder eine Abdeckung angeordnet. Die Abdeckung ist dafür eingerichtet, die Kupplung sowie die Stirnseite der an den Verbinder montierten Tragschienen zu übergreifen. Die Abdeckung weist dazu vorzugsweise entlang ihres Umfangs einen Rand auf, der entsprechend des Umfangs der Tragschiene ausgebildet ist. Die Abdekkung dient nicht nur ästhetischen Gründen, sondern dient auch dazu, um das Eindringen von Fremdkörpern zu verhindern und vor den scharfkantigen Enden der Tragschiene, die beispielsweise aus Blech gefertigt ist, zu schützen.According to one embodiment of the invention, a cover is arranged between one or both of the bearing parts and the respectively attached connector. The cover is adapted to engage over the coupling and the face of the mounting rails mounted on the connector. For this purpose, the cover preferably has an edge along its circumference, which is formed in accordance with the circumference of the mounting rail. The cover not only serves aesthetic reasons, but also serves to prevent the ingress of foreign bodies and to protect against the sharp-edged ends of the support rail, which is made of sheet metal, for example.
Gemäß einer bevorzugten Ausführungsform ist der Verbinder dazu eingerichtet, in einen stirnseitigen Abschnitt einer Tragschiene eingeschoben zu werden. Dazu ist die Außenkontur des Verbinders entsprechend dem Querschnitt des Innenraums der Tragschiene an derem stirnseitigen Abschnitt angepaßt. Bei dieser Art der Verbindung ist im montierten Zustand der Verbinder und vorzugsweise auch das Kupplungselement vollständig von den Tragschienen oder ggf. von der Abdeckung abgedeckt. Es stehen keine Teile hervor, wodurch der optische Eindruck eines durchgängigen Lichtbandes vermittelt wird.According to a preferred embodiment, the connector is adapted to be inserted into a frontal portion of a support rail. For this purpose, the outer contour of the connector is adapted according to the cross section of the interior of the support rail to the frontal end section. In this type of connection in the assembled state, the connector and preferably also the coupling element completely from the mounting rails or possibly covered by the cover. There are no parts, which gives the visual impression of a continuous light band.
Gemäß einer bevorzugten Ausführungsform weist jeder Verbinder wenigstens ein Klemmelement auf, das zum Fixieren des stirnseitigen Abschnitts der Tragschiene an dem Verbinder eingerichtet ist. Vorzugsweise ist das Klemmelement in dem Verbinder angeordnet. Bei einer auf den Verbinder aufgeschobenen Tragschiene wirkt das Klemmelement von innen durch eine Öffnung in dem Verbinder gegen die Tragschiene, um die Tragschiene an dem Verbinder zu fixieren. Das Klemmelement ist dadurch von außen nicht sichtbar, so daß es den optischen Eindruck des Lichtbandes nicht stört.According to a preferred embodiment, each connector has at least one clamping element which is adapted for fixing the front-side portion of the mounting rail to the connector. Preferably, the clamping element is arranged in the connector. With a mounting rail slid onto the connector, the clamping element acts against the mounting rail from the inside through an opening in the connector in order to fix the mounting rail to the connector. The clamping element is thus not visible from the outside, so that it does not interfere with the visual impression of the light band.
Gemäß einer bevorzugten Ausführungsform ist das Klemmelement durch eine Schraubverbindung, mit der es an dem Verbinder verstellbar befestigt ist, gegen einen Abschnitt der Tragschiene verlagerbar, zum Aufbringen einer Klemmkraft, um den Verbinder in einer Tragschiene zu fixieren. Beispielsweise kann das Klemmelement eine Platte sein, die sich durch eine Schraubverbindung senkrecht zur Längserstreckung des Lichtbandes nach außen verlagern läßt. Die Platte kann flächig oder mit Dornen von Innen gegen die Tragschiene gedrückt werden.According to a preferred embodiment, the clamping element is displaceable by a screw, with which it is adjustably attached to the connector, against a portion of the support rail for applying a clamping force to fix the connector in a mounting rail. For example, the clamping element may be a plate which can be displaced outwards by a screw connection perpendicular to the longitudinal extension of the light band. The plate can be pressed flat or with thorns from the inside against the mounting rail.
Die Erfindung bezieht sich ferner auf ein Lichtbandsystem, das wenigstens ein Verbindungssystem und zwei Tragschienen aufweist, die an zwei Seiten des Verbindungssystems an diesem anbringbar sind.The invention further relates to a light strip system comprising at least one connection system and two support rails, which are attachable to this on two sides of the connection system.
Im folgenden wird das Verbindungssystem anhand einer bevorzugten Ausführungsform im Zusammenhang mit den beigefügten Zeichnungen erläutert.

Das Verbindungssystem umfaßt zwei Verbinder 2, die einander gegenüberliegend an jeweils einer Seite einer Kupplung 4 angebracht sind.The connection system comprises two
Die Verbinder sind aus einem etwa U-förmig gebogenen Blechabschnitt gebildet, der im Querschnitt auf die innere Form einer Tragschiene abgestimmt ist, die über den Verbinder der Länge nach mit einem Abschnitt der Stirnseite geschoben wird (die Tragschiene ist in der Figur nicht dargestellt). An den Tragschienen sind eine Durchgangsverdrahtung sowie elektrische Anschlüsse und/oder Anschlußbuchsen angebracht. Die Tragschienen sind ferner dazu eingerichtet, Leuchteneinsätze annzunehmen, welche die Betriebsmittel der Leuchten einschließlich Leuchtmittel, Vorschaltgerät, elektrische Anschlüsse usw. enthalten. Alternativ können auch komplette Leuchten mit einem Leuchtengehäuse direkt an dem Verbinder angebracht werden.The connectors are formed from an approximately U-shaped bent sheet metal section, which is matched in cross-section to the inner shape of a mounting rail, which is pushed over the connector lengthwise with a portion of the end face (the mounting rail is not shown in the figure). On the mounting rails a through-wiring and electrical connections and / or sockets are attached. The DIN rails are also adapted to accept lamp inserts containing the equipment of the lamps including bulbs, ballast, electrical connections, etc. Alternatively, complete luminaires with a luminaire housing can be attached directly to the connector.
An der zur Kupplung weisenden Seite der Verbinder 2 ist ein Blechabschnitt 6 vorgesehen, der eine Stirnseite des Verbinders bildet, an denen die Kupplung montiert werden kann. Zu diesem Zweck sind Löcher in dem Blechabschnitt 6 vorgesehen.On the coupling side facing the
Ferner sind im Verbinder, wie beispielsweise in der Querschnittsansicht gemäß
An den zur Kupplung 4 weisenden Stirnseiten 6 der Verbinder 2 sind Löcher vorgesehen, an denen die Kupplung vorzugsweise formschlüssig und kraftschlüssig durch wenigstens eine Schraube gehalten wird. In der dargestellten Ausführungsform ist eine zentrale Bohrung in der Stirnseite 6 vorgesehen, in der die Kupplung 4 formschlüssig eingreift und zusätzlich ein weiteres kleineres Loch außerhalb der Mitte, in der die Kupplung mit einer weiteren Schraube gegen Verdrehen gesichert ist.At the facing to the
Die Kupplung 4 umfaßt zwei Lagerelemente 16 und 18. Das erste Lagerelement 16 weist einen röhrenförmigen Abschnitt 20 auf, der in eine zylindrische Bohrung 22 des zweiten Lagerelements 18 eingeschoben werden kann. Zwischen dem röhrenförmigen Abschnitt 20 und der zylindrischen Öffnung 22 ist noch eine Buchse 24 angebracht, welche die Lagerflächen der Lagerelemente 16 und 18 schont. An dem äußeren Rand des röhrenförmigen Abschnitts 22 ist in Umfangsrichtung eine Nut 26 vorgesehen, in die im montierten Zustand der Kupplung ein Sprengring 28 aufgeschoben wird. Die montierte Kupplung wird durch den Sprengring 28 in Axialrichtung gehalten, während eine Drehbewegung um ihre Längsachse möglich ist.The
Das erste Lagerelement 16 weist entlang seines äußeren Umfangs eine Vielzahl von Kerben oder Vertiefungen 30 auf, die in der dargestellten Ausführungsform kreisförmig sind. Die Vertiefungen sind in engen Winkelabständen entlang des Umfangs des ersten Lagerelements 16 angeordnet. Das Lagerelement 16 wird an seiner Außenseite von dem zweiten Lagerelement 18 übergriffen. In dem zweiten Lagerelement 18 ist in radialer Richtung eine mit Innengewinde versehene Bohrung 32 vorgesehen, die im montierten Zustand der Kupplung gegenüber den Vertiefungen 30 liegt. In die Bohrung 32 ist eine Madenschraube 34 eingeschraubt, und kann soweit in das Loch 32 eingeschraubt werden, bis die Madenschraube 34 in eine der Vertiefungen 30 des ersten Lagerelements 16 formschlüssig eingreift. Durch die Madenschraube 34, welche auch als Arretierschraube bezeichnet wird, kann die Drehbewegung des Kupplungselements durch den Formschluß der Madenschraube 34 mit einer der Vertiefungen 30 blockiert werden. In der dargestellten Ausführungsform ist eine Vielzahl von Vertiefungen vorgesehen, beispielsweise in Winkelabständen von kleiner oder gleich 45°, bevorzugt kleiner oder gleich 15°, entlang des Umfangs des ersten Lagerelements 16, so daß sich das Kupplungselement nahezu in einem beliebigen Drehwinkel arretieren läßt.The
Gemäß einer alternativen Ausführungsform kann anstelle der Vertiefungen 30 auch eine durchgehende Nut vorgesehen sein, in der die Madenschraube 34 reibschlüssig eingreift. Bei dieser Ausführungsform der Kupplung kann die Kupplung in einem beliebigen Drehwinkel blockiert werden.According to an alternative embodiment, instead of the
In dem ersten Lagerelement 16, dem zweiten Lagerelement 18 sowie in den Stirnseiten 6 der Verbinder 2 sind entlang der Drehachse der Kupplung 4 Durchgänge vorgesehen, durch die eine Durchgangsverdrahtung von einem Verbinder 2 zu dem gegenüberliegenden Verbinder 2 hindurchgeschoben werden kann (die Explosionsdarstellung der
Die Durchgangsverdrahtung 36 ist ein Kabelbündel oder ein Flachbandkabel, welches zum Durchführen durch die Kupplung 4 in der Breite eingerollt sein kann.The through-
Ein Ende der Durchgangsverdrahtung endet in einer elektrischen Anschlußbuchse 37, die in Löchern an der Oberseite des Verbinders 2 eingerastet ist. An der elektrischen Anschlußbuchse 37 läßt sich die Durchgangsverdrahtung 36 zur nächsten Leuchte einstecken (nicht dargestellt), sowie Betriebsmittel einer Leuchte anschließen.One end of the through wiring terminates in an
Zwischen der Stirnwand 6 des Verbinders 2 und dem jeweils angrenzenden Lagerelement 16 bzw. 18 ist in der gezeigten Ausführungsform noch eine Abdeckung 40 angeordnet, die fest zwischen dem Lagerelement und dem jeweiligen Verbinder angebracht ist. Dazu sind Laschen 42 auf der Innenseite der Abdeckung vorgesehen, welche Schraubenöffnungen aufweisen, die mit der oder den entsprechenden Schraubenöffnungen in dem angrenzenden Lagerelement 16 bzw. 18 fluchten. Dadurch werden die Abdeckungen 40 gemeinsam mit dem Lagerelement 16 bzw. 18 an dem jeweiligen Verbinder 2 durch Schrauben gehalten.Between the end wall 6 of the
Die Abdeckung 40 weist einen breiten Rand 44 auf, der sich über die Kupplung 4 in Richtung zu dem Verbinder 2 erstreckt, wobei zwischen dem äußeren Umfang des Verbinders 2 und der Innenseite des Randes 44 ein Abstand verbleibt, der so bemessen ist, daß der äußere Rand einer Tragschiene, die auf den Verbinder 2 aufgeschoben wird, unter den Rand 44 eingeschoben werden kann. Alternativ kann die Tragschiene stirnseitig auch an die Abdeckung 40 stumpf anstoßen. Durch die Abdeckung 40 werden sowohl das Kupplungselement als auch die Ränder der montierten Tragschiene kaschiert. In dem Bereich der Arretierschraube 34 bzw. des Lochs 32 ist eine Aussparung 46 in dem Rand 44 der Abdeckung angeordnet, so daß die Arretierschraube 34 von außen zugänglich bleibt.The cover 40 has a
An dem vorhergehend beschriebenen Verbindungssystem können zahlreiche Änderungen vorgenommen werden, ohne von der Erfindung, wie sie in den Ansprüchen dargelegt ist, abzuweichen. Insbesondere ist es auch möglich, daß das Kupplungselement sich nicht in einer Längsachse erstreckt, sondern zur Bildung einer Eckverbindung zwischen zwei Tragschienen eines Lichtbands gewinkelt ausgebildet ist. Hierzu sind beispielsweise zwei Verbinder 2 mit jeweils einem Lagerelement 18 vorgesehen und der mittlere Bereich wird von einem dritten Lagerelement gebildet, das in beide angrenzenden Lagerelemente eingreift. Insbesondere sind Winkel von 45° oder 90° vorgesehen. Auch bei dieser Ausführungsform ist eine durchgehende Öffnung durch die abgewinkelte Kupplung vorgesehen, um die Durchgangsverdrahtung hindurchzuführen.Numerous changes can be made to the connection system described above without departing from the invention as set forth in the claims. In particular, it is also possible that the coupling element does not extend in a longitudinal axis, but is angled to form a corner joint between two mounting rails of a light band.
