Description

Die Erfindung betrifft ein Lichtbandsystem mit einer länglichen Tragschiene und wenigstens eine Leuchte, die dazu ausgestaltet ist, mit der Tragschiene verbunden zu werden.The invention relates to a light line system with an elongate mounting rail and at least one lamp that is designed to be connected to the mounting rail.

Die Anmelderin vertreibt ein derartiges Lichtbandsystem unter der Bezeichnung "Slotlight Infinity". Bei diesem Lichtbandsystem ist die Tragschiene durch ein im Querschnitt im Wesentlichen U-förmiges Profilelement gebildet, das zum Betrieb derart ausgerichtet wird, dass die beiden U-Schenkel nach unten weisen. Innerhalb des so gebildeten Kanals können von unten kommend balkenförmige Leuchten eingesetzt werden. Die Lichtabgabe erfolgt dabei nach unten.The applicant sells such a light line system under the name "Slotlight Infinity". In this continuous-row system, the mounting rail is formed by a profile element that is essentially U-shaped in cross section, which is aligned for operation in such a way that the two U-legs point downwards. Beam-shaped lights coming from below can be used within the channel formed in this way. The light is emitted downwards.

Es hat sich gezeigt, dass es nicht ohne Weiteres möglich ist, bei einem solchen Lichtbandsystem eine höhere Schutzart zu erzielen. Zwar kann die Unterseite mit Hilfe einer Abdeckung, durch die hindurch die Lichtabgabe erfolgt, gut abgeschlossen werden, jedoch weist die Tragschiene an ihrer Oberseite einige Öffnungen auf, die zum Halten bestimmter weiterer Komponenten des Lichtbandsystems dienen, sowie der Durchführung von Zuführungsleitungen. Zwar lassen sich diejenigen dieser Öffnungen, die nicht gebraucht werden, grundsätzlich durch Tüllen, Stopfen oder dergleichen verschließen, allerdings ist ein solches Vorgehen nicht Praxis-tauglich.It has been shown that it is not easily possible to achieve a higher degree of protection with such a continuous-row system. Although the underside can be closed well with a cover through which the light is emitted, the mounting rail has a few openings on its upper side, which are used to hold certain other components of the light line system and to feed through supply lines. Although those of these openings that are not needed can in principle be closed with grommets, plugs or the like, such a procedure is not practical.

Ein anderes Lichtbandsystem ist in US 2005/0152132 A1 offenbart. Es bezieht sich auf eine gekippt arretierbare Leuchte mit einer hängenden Schienenbefestigung und vertieftem Luftführungskanal. Das System besteht im Wesentlichen aus einer U-förmigen Abdeckung mit einer ersten Oberfläche und zwei benachbarten Befestigungsoberflächen, die über eine Anzahl von Befestigungselementen an einen Verteiler - bzw. Anschlusskasten anmontiert werden kann. Der Verteilerkasten weist an bestimmten Stellen Öffnungen, welche mit entsprechenden Öffnungen im Luftkanal korrespondieren, um Rückluft nur durch definierte, gewünschte Luftrückführungsschlitze zu leiten. Generell deckt die Abdeckung die Luftrückführungsschlitze des Kanals ab.Another light line system is in U.S. 2005/0152132 A1 disclosed. It refers to a tiltable lockable light fixture with a hanging rail mount and recessed air duct. The system essentially consists of a U-shaped cover with a first surface and two adjacent mounting surfaces, which can be attached to a junction box via a number of fasteners. The junction box has openings at certain locations which correspond to corresponding openings in the air duct in order to direct return air only through defined, desired air return slots. Generally, the cover covers the air return slots of the duct.

US 4138716 A bezieht sich auf ein lang gestrecktes Beleuchtungsgehäuse, welches gegenüber Feuchtigkeit, Staub sowie korrosiven Elementen abgedichtet ist und so Bereichen starker Beanspruchung ausgesetzt sein kann. Das Gehäuse besteht im Wesentlichen aus zwei zueinander horizontal abgedichteten Hälften, wobei die untere Hälfte ein nach oben offenes einstückiges, durchscheinendes oder transparentes Kunststoffteil darstellt. Die obere Hälfte enthält sämtliche elektrischen und lichttechnischen Komponenten, ist über Halterungen an der Decke aufgehängt und kann mit einer Vielzahl von Aussparungen versehen sein, um elektrische Verbindungen aufzunehmen. US4138716A refers to an elongated lighting housing that is sealed from moisture, dust, and corrosive elements that may be exposed to high-stress areas. The housing essentially consists of two halves that are horizontally sealed to one another, with the lower Half represents an open-topped one-piece, translucent or transparent plastic part. The top half contains all the electrical and lighting components, is suspended from the ceiling by brackets, and can be provided with a variety of cutouts to accommodate electrical connections.

US 2007/0109795 A1 betrifft ein Wärmeableitsystem für ein Vorschaltgerät eines Beleuchtungssystems insbesondere aus Leuchtstofflampen. Dazu steht ein Ballastgehäuse in Eingriff mit einem länglichen Träger. Das Ballastgehäuse besteht aus wärmeleitfähigem Material in Form von Wärmeübertragungsflächen, die mittels thermischer Reibungspassung in den Träger eingepasst sind. Der Körper des Ballastgehäuses ist im Prinzip eine Wanne, die den Ballast - im Wesentlichen in Form von wärmeerzeugenden Lichtsystemkomponenten - enthält. U.S. 2007/0109795 A1 relates to a heat dissipation system for a ballast of a lighting system, in particular made of fluorescent lamps. For this purpose, a ballast housing is in engagement with an elongate carrier. The ballast housing consists of thermally conductive material in the form of heat transfer surfaces that are thermally friction fit into the carrier. The body of the ballast housing is essentially a trough that contains the ballast - essentially in the form of heat-generating light system components.

US 2012/0162974 A1 bezieht sich ebenfalls auf eine Wärmeableitungsvorrichtung - allerdings für eine (Hochleistungs-)LED-Lampe. Die LED-Lampe umfasst einen Kühlkörper in Form eines länglichen, hohlen aber geschlossenen Extrusionskörpers, auf den ein LED-Modul mit einer Vielzahl an LEDs und genauso vielen Linsenmodulen aufmontiert ist. Darüber befindet sich eine konkave Reflektorschiene, die das LED-Licht reflektiert und wieder darüber eine transparente Platte, die durch zwei Befestigungsstreifen fixiert ist. U.S. 2012/0162974 A1 also refers to a heat dissipation device - but for a (high-power) LED lamp. The LED lamp includes a heat sink in the form of an elongated, hollow but closed extruded body on which an LED module with a large number of LEDs and just as many lens modules is mounted. Above it is a concave reflector rail that reflects the LED light and above it a transparent plate that is fixed by two fastening strips.

EP 2 672 172 A1 betrifft eine Leuchte, insbesondere für ein Lichtband, wobei die Leuchtmittel unterhalb eines Trägers angebracht sind, welcher wiederum den bodenflächigen Abschluss eines Tragprofils bildet. Das Leuchtmittel ist einerseits seitlich mit einem nach unten offenen Reflektor umgeben, andererseits befindet sich direkt unterhalb ein komplex strukturierter Diffusor, der abschnittsweise mit Klammern an der Basis des Reflektors hängend befestigt ist. Der Reflektor hängt mitsamt Leuchtmittel und Diffusor an dem Träger, der bodenseitig mit dem Tragprofil fest verbunden ist. Das Tragprofil wiederum ist an einer Wand oder Decke montiert. WO 2017/202666 A1 betrifft ein Lichtbandsystem mit einer länglichen sich entlang einer Längsachse erstrechenden Tragschiene, die in einem Querschnitt normal zur Längsachse betrachtet in erster Näherung eine U-Form aufweist, sodass ein nach unten weisender erster U-Schenkel, ein nach unten weisender zweiter U-Schenkel und ein, die beiden U-Schenkel miteinander verbindender Verbindungsschenkel gebildet sind.

Gemäß der Erfindung ist ein Lichtbandsystem vorgesehen, das eine längliche, sich entlang einer Längsachse erstreckende Tragschiene aufweist, die in einem Querschnitt normal zu der Längsachse betrachtet in erster Näherung eine U-Form aufweist, so dass ein nach unten weisender erster U-Schenkel, ein nach unten weisender zweiter U-Schenkel und ein, die beiden U-Schenkel miteinander verbindender Verbindungsschenkel gebildet sind; dabei ist in dem Verbindungsschenkel wenigstens eine Durchgangsöffnung gebildet. Weiterhin umfasst das Lichtbandsystem wenigstens eine Leuchte, die dazu ausgestaltet ist, mit der Tragschiene verbunden zu werden. Außerdem weist das Lichtbandsystem wenigstens ein Abdeckelement auf, welches zwei Verbindungsbereiche und einen Deckenbereich aufweist, der die beiden Verbindungsbereiche miteinander verbindend gestaltet ist, und dazu ausgestaltet ist, die wenigstens eine Durchgangsöffnung abdeckend an der Tragschiene montiert zu werden.According to the invention, a light band system is provided which has an elongate support rail which extends along a longitudinal axis and which, viewed in a cross section normal to the longitudinal axis, has a U-shape in a first approximation, so that a downward-pointing first leg of the U, a downward-pointing second leg of the U and a connecting leg connecting the two U-legs to one another are formed; at least one through-opening is formed in the connecting leg. Furthermore, the light line system includes at least one lamp that is designed to be connected to the mounting rail. In addition, the light line system has at least one cover element, which has two connection areas and a ceiling area, which is designed to connect the two connection areas to one another and is designed to be mounted on the mounting rail so as to cover the at least one through-opening.

Die Erfindung ist insbesondere dadurch gekennzeichnet, dass der Verbindungsschenkel eine profilierte Struktur aufweist, durch die eine nach oben offene Ausnehmung gebildet ist, die einen Bodenbereich aufweist, in dem die wenigstens eine Durchgangsöffnung ausgebildet ist, wobei zwischen dem Bodenbereich der Ausnehmung und einem Deckenbereich des Abdeckelements ein vertikaler Abstand gebildet ist, wobei das Abdeckelement länglich ist, wobei die beiden entsprechenden Endbereiche derart gestaltet sind, dass sich das Abdeckelement mit einem weiteren, baugleichen Abdeckelement der Länge nach abdichtend verbinden lässt, und das Abdeckelement an wenigstens einem der beiden Endbereiche eine Dichtlippe aufweist.The invention is characterized in particular in that the connecting leg has a profiled structure which forms a recess which is open at the top and has a base area in which the at least one through-opening is formed, with the base area of the recess and a top area of the cover element being formed between a vertical distance is formed, with the cover element being elongated, with the two corresponding end regions being designed in such a way that the cover element can be sealingly connected lengthwise to another cover element of the same construction, and the cover element having a sealing lip on at least one of the two end regions .

Durch das Abdeckelement lässt sich eine verbesserte Abdichtung des Lichtbandsystems erzielen. Insbesondere lässt sich so erzielen, dass das Lichtbandsystem eine höhere Schutzart erfüllt, beispielsweise die Schutzart IP (ingress protection) 40, gemäß der insbesondere ein Schutz gegen Eindringen von festen Fremdkörpern mit einem Durchmesser von mehr als einem Millimeter gegeben ist.Improved sealing of the light line system can be achieved by the cover element. In particular, it can be achieved in this way that the continuous-row system meets a higher degree of protection, for example degree of protection IP (ingress protection) 40, according to which in particular protection against the ingress of solid foreign bodies with a diameter of more than one millimeter is provided.

Vorzugsweise ist die Durchgangsöffnung kreisförmig oder länglich geformt und insbesondere zur Aufnahme eines Befestigungselements vorgesehen. So eignet sich das Abdeckelement besonders.Preferably, the through-opening has a circular or elongate shape and is provided in particular for receiving a fastening element. So the cover is particularly suitable.

Vorzugsweise ist das Abdeckelement als Profilteil gestaltet. Dies ist herstellungstechnisch vorteilhaft; außerdem lässt sich so besonders geeignet ein ebenmäßiges äußeres Erscheinungsbild erzielen.The cover element is preferably designed as a profile part. This is advantageous in terms of manufacturing technology; moreover, an even external appearance can be achieved in a particularly suitable manner.

Vorzugsweise sind in dem Verbindungsschenkel mehrere Durchgangsöffnungen gebildet, wobei das Abdeckelement dazu ausgestaltet ist, die mehreren Durchgangsöffnungen abdeckend an der Tragschiene montiert zu werden. So lassen sich die mehreren Durchgangsöffnungen besonders einfach abdecken.A plurality of through-openings are preferably formed in the connecting leg, with the cover element being designed to be mounted on the mounting rail so as to cover the plurality of through-openings. In this way, the several passage openings can be covered in a particularly simple manner.

Vorzugsweise ist die Gestaltung derart, dass das Abdeckelement über eine Rastverbindung an der Tragschiene gehalten wird. Auf diese Weise lässt sich erzielen, dass das Abdeckelement besonders handhabungsfreundlich an der Tragschiene montiert werden kann.The design is preferably such that the cover element is held on the mounting rail by a snap-in connection. In this way it can be achieved that the cover element can be mounted on the mounting rail in a particularly easy-to-handle manner.

Die Verbindungsbereiche des Abdeckelements bestehen vorzugsweise aus einem elastischen Material. So lässt sich besonders geeignet eine dichte Verbindung zwischen dem Abdeckelement und der Tragschiene erzielen.The connecting areas of the cover element are preferably made of an elastic material. A tight connection between the cover element and the mounting rail can thus be achieved in a particularly suitable manner.

Vorzugsweise besteht der Deckenbereich des Abdeckelements aus einem weniger elastischen Material. So lässt sich insbesondere eine geeignete Eigensteifigkeit des Abdeckelements erzielen.The top area of the cover element is preferably made of a less elastic material. In particular, a suitable inherent rigidity of the covering element can be achieved in this way.

Vorzugsweise ist das Abdeckelement als Zweikomponenten-Strangpressprofil gestaltet. Dies ist herstellungstechnisch vorteilhaft.The cover element is preferably designed as a two-component extruded profile. This is advantageous in terms of manufacturing technology.

Erfindungsgemäß ist das Abdeckelement länglich, wobei die beiden entsprechenden Endbereiche derart gestaltet sind, dass sich das Abdeckelement mit einem weiteren, baugleichen Abdeckelement der Länge nach abdichtend verbinden lässt. So lässt sich erzielen, dass sich zwei entsprechende Abdeckelemente stirnseitig bzw. der Länge nach geeignet dicht verbinden lassen. Durch eine entsprechende Anzahl von derartigen Abdeckelementen lässt sich dann die Tragschiene über ihre gesamte Länge entsprechend abdecken.According to the invention, the cover element is elongate, with the two corresponding end regions being designed in such a way that the cover element can be connected to a further, structurally identical cover element lengthwise in a sealing manner. In this way it can be achieved that two corresponding cover elements can be connected tightly in a suitable manner on the front side or lengthwise. The mounting rail can then be covered over its entire length by a corresponding number of such cover elements.

Erfindungsgemäß weist dabei das Abdeckelement an wenigstens einem der beiden Endbereiche eine Dichtlippe auf. Auf diese Weise lässt sich eine besonders geeignete Dichtigkeit erzielen.According to the invention, the cover element has a sealing lip on at least one of the two end regions. A particularly suitable tightness can be achieved in this way.

Vorzugsweise ist die wenigstens eine Leuchte dazu ausgestaltet, zur Verbindung mit der Tragschiene zwischen die beiden U-Schenkel eingesetzt zu werden. So lässt sich insbesondere auch eine geeignete Abdichtung der Tragschiene von der, dem Verbindungsschenkel gegenüber liegenden Seite erzielen.The at least one lamp is preferably designed to be inserted between the two U-legs for connection to the mounting rail. In this way, in particular, a suitable sealing of the support rail can also be achieved from the side lying opposite the connecting leg.

Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels und mit Bezug auf die Zeichnungen näher erläutert. Es zeigen:

Die Erfindung betrifft ein Lichtbandsystem mit einer Tragschiene 1, wie sie perspektivisch in geschnittener Form in Fig. 2 dargestellt ist; Fig. 4 zeigt eine der Fig. 2 entsprechende Darstellung mit teilweise durchscheinenden Begrenzungen. Die Tragschiene 1 ist länglich und erstreckt sich entlang einer Längsachse L. Insbesondere kann die Tragschiene 1 als Profilelement gestaltet sein; vorzugsweise besteht die Tragschiene 1 aus einem Metall, beispielsweise Aluminium.The invention relates to a light line system with a mounting rail 1, as shown in perspective in section in 2 is shown; 4 shows one of the 2 Corresponding representation with partially translucent boundaries. The support rail 1 is elongated and extends along a longitudinal axis L. In particular, the support rail 1 can be designed as a profile element; preferably, the support rail 1 consists of a metal, for example aluminum.

Die Tragschiene 1 weist in einem Querschnitt normal zu der Längsachse L betrachtet in erster Näherung eine U-Form auf, so dass ein erster U-Schenkel 2, ein zweiter U-Schenkel 3 und ein, den ersten U-Schenkel 2 mit dem zweiten U-Schenkel 3 verbindender Verbindungsschenkel 4 gebildet sind. Insbesondere ist die Tragschiene 1 dafür vorgesehen, zum Betrieb des Lichtbandsystems derart ausgerichtet zu werden, dass der erste U-Schenkel 2 und der zweite U-Schenkel 3 nach unten weisen und der Verbindungsschenkel 4 nach oben weist.In a cross section, viewed normal to the longitudinal axis L, the support rail 1 has a U-shape to a first approximation, so that a first U-leg 2, a second U-leg 3 and a first U-leg 2 with the second U -Leg 3 connecting connecting leg 4 are formed. In particular, the mounting rail 1 is intended to be aligned for the operation of the light line system in such a way that the first leg 2 of the U and the second leg 3 of the U point downwards and the connecting leg 4 points upwards.

Insbesondere kann der Verbindungsschenkel 4 strukturiert gestaltet sein, so dass geeignete Angriffsflächen für Befestigungselemente, beispielsweise in Form von Halteklammern gebildet sind, durch die sich die Tragschiene 1 befestigen lässt, zum Beispiel an einer Raumdecke. Beispielsweise kann vorgesehen sein, dass die Tragschiene 1 als Anbauteil an der Raumdecke befestigt wird oder mithilfe von Abhänge-Elementen als Pendel-Teil.In particular, the connecting leg 4 can be structured so that suitable contact surfaces for fastening elements, for example in the form of retaining clips, are formed, by which the support rail 1 can be fastened, for example to a ceiling. For example, it can be provided that the support rail 1 is attached to the ceiling as an add-on part or as a pendulum part using suspension elements.

Weiterhin umfasst das Lichtbandsystem wenigstens eine Leuchte, die dazu ausgestaltet ist, mit der Tragschiene 1 verbunden zu werden. Insbesondere kann die Gestaltung derart sein, dass die Leuchte zur Verbindung mit der Tragschiene 1 zwischen die beiden U-Schenkel 2, 3 eingesetzt wird. Vorzugsweise ist die Leuchte dazu ausgestaltet, ein Licht in den unteren Halbraum abzugeben, wenn sie wie vorgesehen mit der Tragschiene 1 verbunden ist.Furthermore, the light line system includes at least one light that is designed to be connected to the mounting rail 1 . In particular, the design can be such that the lamp for connection to the mounting rail 1 between the two U-legs 2, 3 is used. The lamp is preferably designed to emit a light into the lower hemisphere when it is connected to the mounting rail 1 as intended.

Insbesondere kann vorgesehen sein, dass die Leuchte länglich ist, jedoch eine kleinere Länge aufweist als die Tragschiene 1. Besonders bevorzugt sind mehrere entsprechende Leuchten vorgesehen, die der Länge nach eine Reihe bildend mit der Tragschiene 1 verbunden werden können. So lässt sich mit den Leuchten ein langes Lichtband erzeugen.In particular, it can be provided that the lamp is elongated, but has a shorter length than the mounting rail 1. Particularly preferably, several corresponding lamps are provided, which can be connected to the mounting rail 1 to form a row lengthwise. In this way, a long light band can be created with the luminaires.

Vorzugsweise ist die Tragschiene 1 dazu ausgestaltet, in ihrem durch die U-Form gebildeten Innenbereich weiterhin elektrische Leiter aufzunehmen, die zur Stromversorgung der wenigstens einen Leuchte dienen. Außerdem sind elektrische Kontaktierungselemente vorgesehen, die ebenfalls in dem Innenbereich angeordnet werden und die zur elektrischen Stromübertragung zwischen den elektrischen Leitern und der wenigstens einen Leuchte dienen.Preferably, the support rail 1 is designed to continue to accommodate electrical conductors in its interior formed by the U-shape, which are used to power the at least one lamp. In addition, electrical contacting elements are provided, which are also arranged in the interior and are used to transmit electrical current between the electrical conductors and the at least one lamp.

In Fig. 3 ist eine Ansicht der Tragschiene 1 von oben skizziert. In dem Verbindungsschenkel 4 ist wenigstens eine Durchgangsöffnung 5 gebildet, die insbesondere der Halterung bestimmter Komponenten, wie beispielsweise der oben erwähnten Kontaktierungselemente oder einer Durchführung einer elektrischen Zuführungsleitung dient. Dementsprechend sind in dem Verbindungsschenkel 4 vorzugsweise mehrere Durchgangsöffnungen 5, 5' gebildet.In 3 is a view of the mounting rail 1 outlined from above. In the connecting leg 4 at least one through-opening 5 is formed, in particular the mounting of certain components, such as the above mentioned contacting elements or a passage of an electrical supply line is used. Accordingly, a plurality of through-openings 5, 5' are preferably formed in the connecting leg 4.

Beispielsweise kann die wenigstens eine Durchgangsöffnung 5 kreisförmig oder länglich sein; insbesondere kann sie zur Aufnahme eines Befestigungselements, beispielsweise einer Schraube 7 zur Befestigung einer entsprechenden Komponente dienen.For example, the at least one through opening 5 can be circular or oblong; In particular, it can be used to hold a fastening element, for example a screw 7 for fastening a corresponding component.

In Fig. 1 ist ein Ausschnitt aus einem Querschnitt normal zu der Längsachse L der Tragschiene 1 skizziert. Wie aus dieser Figur ersichtlich, weist das Lichtbandsystem weiterhin ein Abdeckelement 6 auf, das dazu ausgestaltet ist, die wenigstens eine Durchgangsöffnung 5, 5' abdeckend an der Tragschiene 1 montiert zu werden. Dies hat den Vorteil, dass die wenigstens eine Durchgangsöffnung 5, 5' abgedeckt wird, so dass ein Eindringen eines Fremdkörpers in den Innenbereich der Tragschiene 1 erschwert ist. Dies ist insbesondere von Vorteil, wenn in dem Verbindungsschenkel 4 mehrere Durchgangsöffnungen 5, 5' gebildet sind und nicht alle dieser Durchgangsöffnungen 5, 5' durch entsprechende Befestigungselemente bzw. Zuführungsleitungen belegt und somit mehr oder weniger verschlossen sind.In 1 a section of a cross section perpendicular to the longitudinal axis L of the support rail 1 is sketched. As can be seen from this figure, the light line system also has a cover element 6, which is designed to be mounted on the mounting rail 1 so as to cover the at least one through-opening 5, 5'. This has the advantage that the at least one through-opening 5, 5' is covered, so that it is more difficult for a foreign body to penetrate into the interior of the mounting rail 1. This is particularly advantageous if several through-openings 5, 5' are formed in the connecting leg 4 and not all of these through-openings 5, 5' are occupied by corresponding fastening elements or supply lines and are therefore more or less closed.

Beispielsweise lässt sich durch das Abdeckelement 6 erzielen, dass die Schutzart IP 40 erzielt wird.For example, the cover element 6 can achieve protection class IP 40.

Vorzugsweise ist das Abdeckelement 6 als Profilteil gestaltet, insbesondere derart, dass es sich mit seiner entsprechenden Profilachse parallel zur Längsachse L der Tragschiene 1 orientiert mit Letzterer verbinden lässt. Dabei ist vorzugsweise die Gestaltung derart, dass das das Abdeckelement 6 so lange ist, dass es wenigstens zwei der mehreren Durchgangsöffnungen 5, 5' abdeckt.The cover element 6 is preferably designed as a profile part, in particular in such a way that it can be connected to the carrier rail 1 with its corresponding profile axis oriented parallel to the longitudinal axis L of the latter. The design is preferably such that the cover element 6 is so long that it covers at least two of the plurality of through-openings 5, 5'.

Vorteilhaft sind mehrere entsprechende bzw. baugleiche Abdeckelemente vorgesehen, die entlang der Längsachse L eine Reihe bildend an der Tragschiene 1 montiert werden können, so dass die Tragschiene 1 entlang ihrer gesamten Längserstreckung entsprechend abgedeckt ist. Hierdurch lässt sich ein besonders geeigneter Schutz erzielen.Several corresponding or structurally identical covering elements are advantageously provided, which can be mounted in a row along the longitudinal axis L on the mounting rail 1, so that the mounting rail 1 is correspondingly covered along its entire length. A particularly suitable protection can be achieved in this way.

Vorzugsweise ist die Gestaltung derart ist, dass das Abdeckelement 6 über eine Rastverbindung R an der Tragschiene 1 gehalten wird. Hierdurch lässt sich erzielen, dass sich das Abdeckelement 6 besonders einfach bzw. handhabungsfreundlich, beispielsweise ohne Zuhilfenahme eines Werkzeugs an der Tragschiene 1 montieren lässt. Durch die Rastverbindung R lässt sich erzielen, dass sich das Abdeckelement 6 an der bereits betriebsfertig eingerichteten Tragschiene 1 montieren lässt. Das Abdeckelement 6 eignet sich daher als "Nachrüst-Teil", durch das eine gewünschte erhöhte Schutzklasse nachträglich bewirkt werden kann.The design is preferably such that the cover element 6 is held on the mounting rail 1 via a latching connection R. This makes it possible for the cover element 6 to be mounted on the mounting rail 1 in a particularly simple and easy-to-handle manner, for example without the aid of a tool leaves. The latching connection R makes it possible for the cover element 6 to be mounted on the mounting rail 1 that is already set up and ready for use. The cover element 6 is therefore suitable as a "retrofit part" through which a desired increased protection class can be brought about later.

Im gezeigten Beispiel umfasst das Abdeckelement 6 zwei Verbindungsbereiche 8, 9, die dazu ausgestaltet sind, bei der Montage des Abdeckelements 6 die Tragschiene 1 kontaktierend angeordnet zu werden, wobei die Verbindungsbereiche 8, 9 aus einem elastischen Material bestehen. So lässt sich eine besonders geeignete Dichtheit zwischen dem Abdeckelement 6 und der Tragschiene 1 bewirken. Die Verbindungsbereiche 8, 9 können dabei als profilartige Armbereiche gestaltet sein, die sich dementsprechend entlang der Profilachse bzw. im montierten Zustand entlang der Längsachse L erstrecken.In the example shown, the cover element 6 comprises two connection areas 8, 9, which are designed to be arranged in contact with the mounting rail 1 when the cover element 6 is installed, the connection areas 8, 9 consisting of an elastic material. A particularly suitable tightness between the cover element 6 and the support rail 1 can thus be brought about. The connecting areas 8, 9 can be designed as profile-like arm areas, which accordingly extend along the profile axis or along the longitudinal axis L in the assembled state.

Durch die Rastverbindung R lässt sich zudem erzielen, dass sich das Abdeckelement 6 an der bereits betriebsfertig eingerichteten Tragschiene 1 montieren lässt. Das Abdeckelement 6 eignet sich daher also ein Nachrüst-Teil, durch das eine gewünschte erhöhte Schutzklasse nachträglich bewirkt werden kann.The latching connection R also makes it possible for the cover element 6 to be mounted on the mounting rail 1 that is already set up and ready for operation. The cover element 6 is therefore suitable as a retrofit part, which can subsequently bring about a desired increased protection class.

Wie im gezeigten Beispiel der Fall, kann das Abdeckelement 6 dabei außerdem einen Deckenbereich 10 aufweisen, der die beiden Verbindungsbereiche 8, 9 miteinander verbindend gestaltet ist, wobei der Deckenbereich 10 aus einem weniger elastischen Material besteht. So lässt sich das Abdeckelement 6 sowohl mit einer geeigneten Eigenstabilität, als auch mit vorteilhaften Rastverbindungseigenschaften gestalten. Zur Herstellung des Abdeckelements 6 eignet sich hierbei zweckmäßig beispielsweise ein Zwei-Komponenten-Strangpressverfahren. Der Deckenbereich 10 kann insbesondere in erster Näherung plan bzw. plattenförmig gestaltet sein.As is the case in the example shown, the cover element 6 can also have a top area 10 which is designed to connect the two connecting areas 8, 9 to one another, the top area 10 being made of a less elastic material. In this way, the covering element 6 can be designed both with suitable inherent stability and with advantageous snap-in connection properties. A two-component extrusion process, for example, is expediently suitable for producing the cover element 6 . In a first approximation, the ceiling area 10 can in particular be planar or plate-shaped.

Im gezeigten Beispiel weist der Verbindungsschenkel 4 eine profilierte Struktur auf, durch die eine nach oben offene Ausnehmung 40 gebildet ist, die einen Bodenbereich 45 aufweist, sowie zwei seitliche Begrenzungsbereiche 42, wobei die wenigstens eine Durchgangsöffnung 5, 5' in dem Bodenbereich 45 ausgebildet ist. Dabei ist das Abdeckelement 6 vorzugsweise derart gestaltet, dass es - wie in Fig. 1 beispielhaft skizziert - die Ausnehmung 40 abdeckt bzw. überdeckt.In the example shown, the connecting leg 4 has a profiled structure that forms a recess 40 that is open at the top and has a base area 45, as well as two lateral boundary areas 42, with the at least one through-opening 5, 5' being formed in the base area 45 . The cover element 6 is preferably designed in such a way that - as in 1 outlined as an example - the recess 40 covers or covers.

Im gezeigten Beispiel ist die profilierte Struktur des Verbindungsschenkels 4 weiterhin derart gestaltet, dass zwei Haltebereiche 41 gebildet sind, die als Angriffsflächen für wenigstens eine Halteklammer 50 dienen, die beispielsweise für eine Befestigung der Tragschiene 1 an einer Raumdecke vorgesehen ist oder für die Verbindung mit einem Seil oder einem anderen Abhänge-Element zur abgehängten Befestigung der Tragschiene 1. Im gezeigten Beispiel sind die beiden Haltebereiche 41 vorteilhaft als Teile der beiden seitlichen Begrenzungsbereiche 42 der Ausnehmung 40 gestaltet.In the example shown, the profiled structure of the connecting leg 4 is also designed in such a way that two holding areas 41 are formed, which serve as contact surfaces for at least one holding clip 50, which is provided, for example, for fastening the support rail 1 to a ceiling or for connecting to a Cable or another suspension element for suspended attachment of the support rail 1. In the example shown, the two holding areas 41 are advantageously designed as parts of the two lateral boundary areas 42 of the recess 40.

Im gezeigten Beispiel weisen die beiden seitlichen Begrenzungsbereiche 42 der Ausnehmung 40 jeweils eine längliche Nut auf, wobei die so gebildeten beiden Nuten zur Aufnahme der beiden Verbindungsbereiche 8, 9 ausgestaltet sind. Die Verbindungsbereiche 8, 9 können hierbei besonders vorteilhaft derart gebogen gestaltet sein, dass sie bei der Montage des Abdeckelements 6 an der Tragschiene 1 in die Nuten einrasten, so dass hierdurch die oben erwähnte Rastverbindung hergestellt ist, durch die das Abdeckelement 6 an der Tragschiene 1 gehalten ist.In the example shown, the two lateral delimiting areas 42 of the recess 40 each have an elongated groove, the two grooves formed in this way being designed to accommodate the two connecting areas 8 , 9 . The connection areas 8, 9 can be particularly advantageously curved in such a way that they snap into the grooves when the cover element 6 is mounted on the mounting rail 1, so that the above-mentioned snap-in connection is produced by which the cover element 6 is attached to the mounting rail 1 is held.

Wie aus Fig. 1 hervorgeht, kann die Gestaltung vorteilhaft derart sein, dass zwischen dem Bodenbereich 45 der Ausnehmung 40 und dem Deckenbereich 10 des Abdeckelements 6 ein vertikaler Abstand gebildet ist, der beispielsweise etwa so groß ist wie die Höhe der beiden seitlichen Begrenzungsbereiche 42. Auf diese Weise lässt sich erzielen, dass ein in die Durchgangsöffnung 5 eingreifendes Befestigungselement durch das Abdeckelement 4 ebenfalls abgedeckt wird.How out 1 shows, the design can advantageously be such that a vertical distance is formed between the bottom region 45 of the recess 40 and the top region 10 of the cover element 6, which is, for example, approximately as large as the height of the two lateral boundary regions 42. In this way, achieve that an engaging in the through-opening 5 fastener is also covered by the cover 4.

Wie bereits kurz erwähnt, können über die gesamte Längserstreckung der Tragschiene 1 hinweg entsprechende Abdeckelemente montiert werden und dabei Stirn an Stirn aneinander angeordnet werden. Um die Länge der Abdeckelemente mit der Länge der Tragschiene 1 in Übereinstimmung zu bringen, kann gegebenenfalls eines der Abdeckelemente entsprechend gekürzt werden.As already briefly mentioned, corresponding cover elements can be mounted over the entire longitudinal extension of the mounting rail 1 and arranged face to face on one another. In order to match the length of the cover elements with the length of the support rail 1, one of the cover elements can be shortened accordingly if necessary.

Entsprechend gestaltete Endkappen 51, 52 können dazu vorgesehen sein, die Abdeckelemente entlang der Längsachse L betrachtet zu arretieren, so dass sie sich parallel zur Längsachse L nicht mehr bewegen können. Die Endkappen 50, 51 können - wie in Fig. 2 skizziert, so gestaltet sein, dass sie auch den Innenbereich der Tragschiene 1 entsprechend abschließen.Appropriately designed end caps 51, 52 can be provided to lock the cover elements viewed along the longitudinal axis L, so that they can no longer move parallel to the longitudinal axis L. The end caps 50, 51 can - as in 2 outlined, be designed so that they complete the interior of the mounting rail 1 accordingly.

Erfindungsgemäß ist das Abdeckelement 6 länglich, wobei die beiden entsprechenden Endbereiche derart gestaltet sind, dass sich das Abdeckelement 6 mit einem weiteren, baugleichen Abdeckelement der Länge nach abdichtend verbinden lässt. So lässt sich auch an den längsseitigen Endbereichen des Abdeckelements eine geeignete Dichtigkeit erzielen. Erfindungsgemäß weist das Abdeckelement 6 hierzu an wenigstens einem der beiden Endbereiche eine Dichtlippe auf. Die Gestaltung kann auch derart sein, dass ein endseitiges Ineinandergreifen ermöglicht ist, so dass zwei benachbarte Abdeckelemente etwas überlappend angeordnet werden können.According to the invention, the cover element 6 is elongate, with the two corresponding end regions being designed in such a way that the cover element 6 can be sealingly connected lengthwise to a further, structurally identical cover element. In this way, a suitable achieve tightness. According to the invention, the cover element 6 has a sealing lip on at least one of the two end regions. The design can also be such that an end-to-end interlocking is made possible, so that two adjacent cover elements can be arranged with a slight overlap.

Wie erwähnt, kann mit Hilfe des Abdeckelements 6 beispielsweise die Schutzart IP 40 erzielt werden. Allerdings kann - je nach Ausgestaltung der Abdeckelemente 6 - auch eine noch höhere Schutzart erzielt werden. Beispielsweise kann hierzu die Querschnittform des Abdeckelements 6 entsprechend angepasst werden und/oder das zur Herstellung des Abdeckelements 6 verwendete Material entsprechend gewählt werden. Beispielsweise lässt sich das Abdeckelement 6 auch so gestalten, dass ein Schutz vor einem Eindringen von Staub oder Feuchtigkeit erzielt wird.As mentioned, the protection class IP 40 can be achieved with the help of the cover element 6, for example. However--depending on the configuration of the cover elements 6--an even higher degree of protection can also be achieved. For example, the cross-sectional shape of the cover element 6 can be adapted accordingly and/or the material used to produce the cover element 6 can be selected accordingly. For example, the cover element 6 can also be designed in such a way that protection against the ingress of dust or moisture is achieved.

Um eine elektrische Zuführung zu ermöglichen, die von außen kommend in den Innenbereich des Tragschiene 1 führt, kann vorgesehen sein, dass das Abdeckelement 6 mit einem entsprechenden Durchführungsloch versehen werden kann bzw. versehen wird, durch das eine entsprechende Zuführungsleitung geführt werden kann; zur Abdichtung kann hierbei beispielsweise eine Tülle vorgesehen werden, die der gewünschten Schutzart entspricht.In order to enable an electrical supply which, coming from the outside, leads into the interior of the mounting rail 1, it can be provided that the cover element 6 can be or is provided with a corresponding lead-through hole through which a corresponding supply line can be routed; a grommet, for example, which corresponds to the desired degree of protection, can be provided for sealing purposes.
