Abstract

Pictures or other objects hung on a wall could be illuminated hitherto by means of compact lamps in an unsatisfactory manner in terms of design. In order to achieve an improvement both in respect of the construction and the design, the picture rail is constructed as a profile rail (6) which serves at the same time as an electric conductor and is connected to a current supply. The hanging elements (7) are likewise constructed as electric conductors and are in connection via contact heads with the respective electric phase of the profile rail (6). A lamp (11) can then be attached to the hanging elements (7), the support parts of which lamp form the electric conductors at the same time. This enables a filigree-type design if thin or possibly springy wires are used. <IMAGE>

Description

Die Erfindung betrifft eine Galerielieste zum Hängen Von Objekten, insbesondere Bildern, entsprechend dem Oberbegriff des Anspruchs 1. Galerieleisten der eingangs bezeichneten Art sind beispielweise aus der CH-A-655 900 bekannt. Um nun an derartigen Galerieleisten aufgehängte Objekte, beispielsweise Bilder, beleuchten zu können, war hierbei als Hängesystem eine Hohlprofilstange vorgesehen, die an einem Ende mit einem Anschlußadapter zum Anschluß an eine Stromschiene und an anderen Ende mit einem verschiebbaren Haken versehen ist Die Zuleitungskabel, die an den Adapter angeschlossen sind, werden in die Profilstange eingelegt und mit dem ebenfalls an der Profilstange angeklemmten Beleuchtungskörper verbunden. Eine derartige Anordnung, genügt modernen ästhetischen Anforderungen nicht.The invention relates to a gallery list for hanging objects, in particular pictures, according to the preamble of claim 1. Gallery bars of the type mentioned at the outset are known, for example, from CH-A-655 900. In order to be able to illuminate objects, such as pictures, suspended from such gallery strips, a hollow profile rod was provided as the hanging system, which is provided at one end with a connection adapter for connection to a power rail and at the other end with a sliding hook the adapter are connected, are inserted into the profile rod and connected to the lighting fixture, which is also clamped to the profile rod. Such an arrangement does not meet modern aesthetic requirements.

Der Erfindung liegt die Aufgabe zugrunde, eine Galerieleiste zu schaffen, die zugleich die elektrische Installation führ den Anschluß von Leuchten enthält, die nahezu unauffällig ist und ästhetische Gestaltungen zulässt.The invention has for its object to provide a gallery bar, which also contains the electrical installation for the connection of lights, which is almost inconspicuous and allows aesthetic designs.

Diese Aufgabe wird erfindungsgemäß mit dem im Kennzeichungsteil des Anspruchs 1 angegebenen Mitteln gelöst, Diese Anordnung erlaubt es, unter Ausnutzung des geringen Gewichtes derartiger NiedervoltLeuchten, das Hängeelement für das Objekt zugleich zur Stromversorgung der dem Objekt zuzuordnenden Leuchte einzusetzen. Das Hängeelement kann hierbei als zweiadriger elektrischer Leiter ausgebildet sein, wobei der Kontaktkopf entsprechend zwei mit den beiden Teilen der Kontaktschiene verbindbare Kontakte aufweist. Die Leuchte selbst kann hierbei unmittelbar am Bild befestigt sein. Besonders einfach ist es, wenn das Hängeelement nur eine stromführende Ader bildet so daß je Objekt zwei Hängeelemente einzusetzen sind. Besonders vorteilhaft ist es hierbei, das Hängeelement aus einem steifen Metalldraht herzustellen, der zugleich als Tragteil für die Leuchte dient. Damit ist es möglich, unter Ausnutzung des geringen Gewichtes von Niedervolt-Leuchten, die Leuchten mit Abstand oberhalb des aufgehängten Objekten unmittelbar an den beiden Hängeelementen zu befestigen.This object is achieved according to the invention with the means specified in the characterizing part of claim 1. This arrangement makes it possible, using the low weight of such low-voltage lamps, to use the hanging element for the object at the same time to supply power to the lamp to be assigned to the object. The hanging element can be designed as a two-wire electrical conductor, the contact head correspondingly having two contacts that can be connected to the two parts of the contact rail. The lamp itself can be attached directly to the picture. It is particularly simple if the hanging element forms only one current-carrying wire so that two hanging elements are to be used for each object. It is particularly advantageous here to produce the hanging element from a rigid metal wire, which also serves as a supporting part for the lamp. This makes it possible, using the low weight of low-voltage luminaires, to attach the luminaires directly to the two hanging elements at a distance above the suspended objects.

Besonders zweckmäßig ist es gemäß einer Ausgestaltung der Erfindung hierbei, wenn die Leuchte über wenigstens zwei im wesentlicher steife und als Stromleiter dienende Metalldrähte im Abstand zur Gebäudewandung gehalten wird, deren Enden jeweils mit einem Hängeelement verbunden sind. Diese von den Hängeelementen abzweigenden Metalldrähte dienen wiederum sowohl als Tragteile für die Leuchte als auch als elektrische Leiter für die Stromversorgung der Leuchte. Der besondere Vorteil dieser Ausbildung besteht darin, daß von den Leuchten praktisch nur das Leuchtmittel mit dem zugehörigen Reflektor im Raum sichtbar ist, während die Verbindung zur Wand über die Stahldrähte nahezu unsichtbar ist. Hierdurch ergibt sich eine besonders ansprechende Raumgestaltung, da der Betrachter nur den dem zu beleuchteten Objekt zugeordneten "Lichtpunkt" wahrnimmt, da die zugehörige Verbindung zur Gebäudewand praktisch nicht sichtbar ist. Je nach dem gewünschten Kragabstand können zusätzliche drahtförmige Abstützungen aus dem gleichen Drahtmaterial vorgesehen sein, die sich entweder unmittelbar auf der Gebäudewand oder in Dreieckform am Hängeelement oder am aufgehängten Objekt abstützen.It is particularly expedient according to an embodiment of the invention if the lamp is kept at a distance from the wall of the building via at least two essentially rigid metal wires serving as current conductors, the ends of which are each connected to a hanging element. These metal wires branching off the hanging elements in turn serve both as supporting parts for the lamp and as electrical conductors for the power supply to the lamp. The particular advantage of this design is that practically only the illuminant with the associated reflector is visible in the room from the lights, while the connection to the wall via the steel wires is almost invisible. This results in a particularly appealing interior design, since the viewer only perceives the "light point" assigned to the object to be illuminated, since the associated connection to the building wall is practically invisible. Depending on the desired cantilever distance, additional wire-shaped supports made of the same wire material can be provided, which are supported either directly on the building wall or in a triangular shape on the hanging element or on the suspended object.

In Ausgestaltung der Erfindung ist vorgesehen, daß die Profilschiene zwei elektrisch gegeneinander isoliert zusammenfügbare Profilhälften aufweist, die jeweils wenigstens teilweise aus elektrisch leitendem Material bestehen. Diese Ausgestaltung hat den Vorteil der einfachen Montage, da die eine Profilhälfte an die Wand angeschraubt werden kann und dann die andere, außenliegende Profilhäfte, beispielsweise über eine Schnappverbindung von außen aufgeklippt werden kann, so daß die Befestigung nicht sichtbar ist. Besonders zweckmäßig ist es, wenn die Profilhälften aus einem elektrisch leitendem Werkstoff, beispielsweise Aluminium, hergestellt werden, da dann bei entsprechend symmetrischer Ausbildung der Profilhälften nur eine einzige Profilkontur konzipiert zu werden braucht. Hierbei ist es jedoch erforderlich, daß die beiden Profilhälften über stopfenförmige oder Ieistenförmige Haltekörper aus einem Isolierwerkstoff miteinander verbunden sind. Da schon aus Festigkeitsgründen der Querschnitt jeder Profilhälfte groß bemessen sein muß, ergibt sich als weiterer Vorteil, daß bei den üblichen Raumlängen sich kein durch die als Leiter dienenden Profilhälften bewirkter Spannungsabfall ergibt Dies erlaubt es, die Stromversorgung jeweils am Ende einer Profilschiene anzuschließen.In an embodiment of the invention, it is provided that the profile rail has two profile halves which can be electrically insulated from one another and which each consist at least partially of electrically conductive material. This configuration has the advantage of simple assembly, since one profile half can be screwed onto the wall and then the other, external profile half can be clipped on from the outside, for example via a snap connection, so that the fastening is not visible. It is particularly expedient if the profile halves are made from an electrically conductive material, for example aluminum, since only a single profile contour then has to be designed with a correspondingly symmetrical design of the profile halves. Here, however, it is necessary that the two profile halves are connected to one another via plug-shaped or bar-shaped holding bodies made of an insulating material. Since the cross-section of each profile half must be large for reasons of strength, there is a further advantage that there is no voltage drop caused by the profile halves serving as conductors in the usual room lengths. This makes it possible to connect the power supply to the end of a profile rail.

In einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß für die Isolierung der Profilhälften gegeneinander eine durchgehende Leiste aus einem elektrischisolierendem Werkstoff vorgesehen ist, die eine durchgehende nutförmige Ausnehmung zur Aufnahme eines Stromkabels aufweist.In an advantageous embodiment of the invention it is provided that a continuous strip made of an electrically insulating material is provided for the insulation of the profile halves against each other, which has a continuous groove-shaped recess for receiving a power cable.

Diese Anordnung erlaubt es, die Galerieleiste zusätzliche als "Kabelkanal" für ein 220 Volt-Kabel zu verwenden, so daß bei sehr langen Räumen eine durchgehende Galerieleiste in mehrere Teilstücke unterteilt werden kann, wobei jedes Teilstück mit einer eigenen Niedervolt-Stromversorgung in Verbindung steht, die jedoch ihrerseits über das durch die Galerieleiste geführte 220 Volt-Kabel gespeist wird.This arrangement allows the gallery bar to be used additionally as a "cable duct" for a 220 volt cable, so that in very long rooms a continuous gallery bar can be divided into several sections, each section being connected to its own low-voltage power supply, which in turn is fed via the 220 volt cable that runs through the gallery bar.

In zweckmäßiger Ausgestaltung der Erfindung ist vorgesehen, daß die Ränder der Ausnehmung federnd ausgebildet sind und die Ausnehmung wenigstens teilweise überdecken. Bei einer derart stranggespreßten aus einem Kunststoffmaterial hergestellten Leiste bietet diese Ausgestaltung die Möglichkeit, das 220 Volt-Kabel in die nutförmige Ausnehmung "einzuklippsen", so daß das Kabel in der Leiste gehalten ist und sichergestellt ist, daß auch bei einem schadhaften Kabel die mit Niederspannung gespeisten, nicht mit einem Isoliermantel versehenen Hängeelemente über die Profilhälften der Profilschiene mit dem Kabel in Verbindung kommen Können.In an advantageous embodiment of the invention it is provided that the edges of the recess are resilient and at least partially cover the recess. With such an extruded strip made of a plastic material, this embodiment offers the possibility of the 220 volt cable "Clip" into the groove-shaped recess so that the cable is held in the bar and it is ensured that even with a defective cable, the low-voltage, not provided with an insulating jacket hanging elements can come into connection with the cable via the profile halves of the profile rail .

In weiterer Ausgestaltung der Erfindung ist vorgesehen, daß wenigstens eine Profilhälfte mit mehreren im Abstand zueinander angeordneten Ausklinkungen zum Einführen eines Kontaktkopfes versehen ist. Diese Ausgestaltung erlaubt einen einfachen Wechsel von Hängeelementen und/oder auch von unmittelbar mit einem Kontaktkopf versehenen Leuchten, ohne daß hierzu die gesamte Hängung an einer Wand durch Verschieben verändert werden muß.In a further embodiment of the invention, it is provided that at least one profile half is provided with a plurality of notches arranged at a distance from one another for inserting a contact head. This configuration allows a simple change of hanging elements and / or also of lights directly provided with a contact head, without the entire hanging on a wall having to be changed by shifting.

In Fig. 1 ist in einem Teilschnitt durch einen Raum eine Bilderwand mit mehreren Bildern 1, 2 und 3 dargestellt. An der Gebäudewand 5 ist im Deckenbereich eine Profilschiene 6 befestigt, an der über jeweils zwei Hängeelernente 7 die betreffenden Bilder abgehängt sind. Über hier nicht näher dargestellte Befestigungsmittel können die einzelnen Bilder höheneinstellbar an den Hängeelementen 7 befestigt werden. Über einen mit dem Hängeelement 7 jeweils verbundenen Kontaktkopf 8, dessen Aufbau nachstehend noch näher beschrieben werden wird, sind die Hängeelemente 7 in der Profilschiene 6 formschlüssig gehalten, so daß die Bilder durch einfaches seitliches Verschieben der jeweiligen Hängeelemente 7 auch in Längsrichtung in einfacher Weise ausgerichtet werden können.In Fig. 1, a picture wall with several pictures 1, 2 and 3 is shown in a partial section through a room. A profile rail 6 is fastened to the building wall 5 in the ceiling area, on which the pictures in question are suspended via two suspension elements 7 each. The fastening means, which are not shown in detail here, can be attached to the hanging elements 7 in a height-adjustable manner. Via a contact head 8 each connected to the hanging element 7, the structure of which will be described in more detail below, the hanging elements 7 are held in a form-fitting manner in the profile rail 6, so that the images can also be aligned in the longitudinal direction in a simple manner by simply moving the respective hanging elements 7 laterally can be.

Die Profilschiene 6 ist entweder mit einer zweipoligen Kontaktschiene versehen oder, wie nachstehend noch näher beschrieben werden wird, selbst als zweipolige Kontaktschiene ausgebildet und an eine Niederspannung-Strornversorgung 9 angeschlossen. Diese wird beispielsweise durch einen Transformator gebildet, der ggf. wählbar eine Niederspannung von beispielsweise 6 bis 24 Volt abgibt. Die Niederspannungs-Stomversorgung 9 ist über ein Zuleitungskabel 10 an die normale Stromversorgung, beispielsweise eine 220 Volt-Spannung angeschlossen.The profile rail 6 is either provided with a two-pole contact rail or, as will be described in more detail below, itself designed as a two-pole contact rail and connected to a low-voltage power supply 9. This is formed, for example, by a transformer, which optionally supplies a low voltage of, for example, 6 to 24 volts. The low-voltage power supply 9 is connected to the normal power supply, for example a 220 volt voltage, via a supply cable 10.

Die Hängeelemente 7 sind nun als elektrischer Leiter ausgebildet, beispielsweise in Form einer Drahtlitze, vorzugsweise aber auch in Form eines federnd-steifen Stahldrahtes, wobei der Kontaktkopf 8 so ausgebildet ist, daß er wahlweise mit dem einen Pol und dem anderen Pol der Profilschiene 6 in Verbindung steht Damit ist für jede Hängung eine Stromzuführung für Leuchten 11, 12 oder 13 geschaffen die nachstehend noch näher beschrieben werden wird. Die Hängeelemente 7 sind ohne, können jedoch auch mit Isoliermantel ausgeführt sein.The hanging elements 7 are now designed as an electrical conductor, for example in the form of a wire strand, but preferably also in the form of a resiliently rigid steel wire, the contact head 8 being designed such that it can be optionally with one pole and the other pole of the profile rail 6 in Connection is established This creates a power supply for lights 11, 12 or 13 for each hanging, which will be described in more detail below. The hanging elements 7 are without, but can also be designed with an insulating jacket.

Die Leuchte 11 ist in einer Seitenansicht in Fig. 2 dargestellt. Die Leuchte 11 besteht beispielsweise aus einer handelsüblichen Niedervolt-Lampe mit integriertem Reflektor und ist über zwei als elektrische Leiter ausgebildete, federnd-steife Stahldrähte 15 jeweils mit den beiden Hängeelementen 7 des Bildes 1 verbunden. Die Drähte 15 bilden somit zugleich als elektrische Leiter ausgebildete "Hängeelemente" für die Leuchte 11, über die sie mit der als Kontaktschiene dienenden Profilschiene 6 verbunden ist Die Befestigung der freien Enden der Drähte 15 an den Hängeelementen 7 erfolgt über entsprechende Halteelemente 16, die über eine Klemm- oder Schraubverbindung an den Hängeelementen 7 verschiebbar festgelegt sind, so daß eine genaue Einjustierung der Leuchte 11 in bezug auf das zu beleuchtende Bild 1 möglich ist. Durch die Verwendung eines federndsteifen Drahtes, beispielsweise eines Stahldrahtes, ergibt sich für die Hängeelemente 7 und die die Leuchte 11 mit den Hängeelementen 7 verbindenden Drähte 15 eine filigranartige, praktisch "unsichtbare" Gestaltungsmöglichkeit. Außer der in Fig. 2 dargestellten freien Biegekurve erlaubt die Verwendung eines federnd-steifen Drahtes als Trägerelement für die Leuchte 11 vielfältige gewillkürte Gestaltungsmöglichkeiten bei der Verwendung von mehreren miteinander verbundenen Drähten, wobei die Formgebung über unterschiedliche, sich gegenseitig beeinflussende Biegekräfte gestaltbar ist.The lamp 11 is shown in a side view in FIG. 2. The lamp 11 consists, for example, of a commercially available low-voltage lamp with an integrated reflector and is connected to the two hanging elements 7 of FIG. 1 via two spring-stiff steel wires 15 designed as electrical conductors. The wires 15 thus form at the same time formed as electrical conductors "hanging elements" for the lamp 11, via which it is connected to the profile rail 6 serving as a contact rail. The free ends of the wires 15 are attached to the hanging elements 7 by means of corresponding holding elements 16, which a clamp or screw connection on the hanging elements 7 are slidably fixed, so that an exact adjustment of the lamp 11 with respect to the image 1 to be illuminated is possible. The use of a spring-stiff wire, for example a steel wire, results in a filigree, practically “invisible” design option for the hanging elements 7 and the wires 15 connecting the lamp 11 to the hanging elements 7. In addition to the free bending curve shown in FIG. 2, the use of a resiliently rigid wire as a carrier element for the lamp 11 allows a variety of arbitrary design options when using a plurality of interconnected wires, the shape being able to be designed using different, mutually influencing bending forces.

Die Hängung gem. der Linie III-III zeigt eine Ausführungsform, bei der die beiden Bilder 2 und 3 gemeinsam an zwei Hängeelementen 7 an der Profilschiene 6 abgehängt sind. Auch hier sind die Hängeelemente 7 wie derum als elektrische Leiter ausgebildet, wobei jedem Bild ohne zusätzliche Zuleitung eine eigene Leuchte 12 bzw. 13 zugeordnet werden kann. Die Leuchte 12 ist in einer anderen etwas steiferen Gestaltung mit den Hängeelementen 7 unmittelbar verbunden, während die Leuchte 13 am Rahmen des Bildes 3 befestigt ist, wobei die Stromversorgung über entsprechende Zuleitungen 16' von den Hängeelementen 7 auf der Rückseite des Bildes abgegriffen wird. Die Anordnung gem. Fig. 3 zeigt ferner die Möglichkeit die Profilschiene 6 im Deckenbereich in gleicher Weise wie für Gardinenschienen bekannt ist, unter Putz zu verlegen.The hanging acc. the line III-III shows an embodiment in which the two images 2 and 3 are suspended together on two hanging elements 7 on the profile rail 6. Here too, the hanging elements 7 are again designed as electrical conductors, and each image can be assigned its own lamp 12 or 13 without an additional supply line. In another somewhat stiffer design, the lamp 12 is directly connected to the hanging elements 7, while the lamp 13 is attached to the frame of the picture 3, the power supply via corresponding supply lines 16 'from the hanging elements 7 on the back of the Image is tapped. The arrangement acc. Fig. 3 also shows the possibility to lay the profile rail 6 in the ceiling area in the same way as is known for curtain rails.

Während bei entsprechender Bemessung des Leiterquerschnittes der stromführenden Teile der Profilschiene 6 praktisch kein Spannungsabfall über die Länge der Stromschiene auftritt, entsteht bei der Verwendung eines federnd-biegbaren Stahldrahtes für die Hängeelemente 7 und 15 infolge des gegenüber normalen elektrischen Leitern etwas höheren elektrischen Widerstandes je Leuchte ein entsprechender Spannungsabfall. Bei den üblichen Längen für derartige Hängeelement Jassen sich jedoch mit den üblichen Leistungen von Niedervolt-Trafos vier Leuchten je Profilschieneneinheit problemlos betreiben. Bei besonders langen Bilderwänden ist es jedoch zweckmäßig, die Profilschiene 6 zu unterteilen und, wie Fig. 1 zeigt, eine weitere Niederspannungs-Stromversorgung 9' zwischenzuschalten, die jeweils der Stromversorgung der anschließenden Profilschiene 6' dient. Der Anschluß an die Stromversorgung ist jeweils durch einen Pfeil kenntlich gemacht.While with appropriate dimensioning of the conductor cross-section of the current-carrying parts of the profile rail 6 there is practically no voltage drop over the length of the conductor rail, a spring-bendable steel wire is used for the hanging elements 7 and 15 due to the somewhat higher electrical resistance per luminaire compared to normal electrical conductors corresponding voltage drop. With the usual lengths for such hanging elements Jassen, however, four lights per profile rail unit can be operated with the usual performance of low-voltage transformers. In the case of particularly long picture walls, however, it is expedient to subdivide the profile rail 6 and, as shown in FIG. 1, to interpose a further low-voltage power supply 9 ', which in each case serves to supply power to the subsequent profile rail 6'. The connection to the power supply is indicated by an arrow.

In Fig. 4 ist in größerem Maßstab im-Schnitt eine Ausführungsform für eine Profilschiene 6 dargestellt. Diese besteht im wesentlichen aus zwei Profilhälften 18' und 18'', die beispielsweise aus Aluminium stranggepreßt und damit elektrisch leitend sind. Die beiden Profilhälften 18' und 18" sind über mehrere über die Länge der Profilschiene verteilte stopfenartige Haltekörper 19 aus einem Isolierwerkstoff miteinander verbunden, wobei die Profilschiene 6 insgesamt über die Haltekörper 19 fest mit der Gebäudewand verschraubt sind. Durch eine entsprechende Bohrung 20 in der wandseitigen Profilhälfte 18', in die ein entsprechender Ansatz am Haltekörper 19 eingreift, ist für eine einwandfreie, beide Profilhälften gegeneinander isolierende Befestigung gesorgtIn Fig. 4, an embodiment for a profile rail 6 is shown on a larger scale in section. This consists essentially of two profile halves 18 'and 18' ', which are extruded from aluminum, for example, and are therefore electrically conductive. The two profile halves 18 'and 18 "are connected to one another via a plurality of stopper-like holding bodies 19 made of an insulating material and distributed over the length of the profile rail, the profile rail 6 being firmly screwed to the building wall via the holding bodies 19 as a whole. Through a corresponding hole 20 in the wall side Profile half 18 ', in which a corresponding approach engages on the holding body 19, ensures that the two profile halves are mutually insulated from one another without any problems

Die beiden, die Profilschiene 6 bildenden Profilhälften 18' und 18'' sind symmetrisch, so daß mit nur einer Profilform gearbeitet werden kann. Die Profilform ist so gewählt, daß im zusammengebauten Zustand, wie in Fig. 5 dargestellt, sowohl an der Oberseite wie auch an der Unterseite eine durchlaufende Nut 21 nach Art einer Hammerkopfnut entsteht. In die Nut 21 wird nun von der Stirnseite her oder über Ausklinkungen 22 in der wandseitigen Profilhälfte 18', die mit Abstand über die Länge verteilt angeordnet sind, ein Kontaktkopf 8 eingeschoben, der am freien Ende des Hängeelementes 7 befestigt ist. Der Kontaktkopf 8 besteht hierbei aus einem Isolierkörper 24, in dem ein mit dem Hängeelement 7 verbundenerTragnippel 25 aus elektrisch leitendem Material fest verbunden ist. Da jede Profilhälfte jeweils eine Phase der die elektrische Stromversorgung bildenden Profilschiene 6 bildet, ist hierdurch gewährleistet, daß ein Hängeelement 7 immer nur mit einer Phase der Stromversorgung in Verbindung stehen kann. Da der Kontaktkopf 8 im übrigen symmetrisch ausgebildet ist, kann somit wahlweise durch entsprechende Ausrichtung des Isolierkörpers 24 jeweils eine der Profilhälften in elektrisch leitende Verbindung mit dem Hängeelement gebracht werden.The two profile halves 18 'and 18' 'which form the profile rail 6 are symmetrical, so that it is possible to work with only one profile shape. The profile shape is chosen so that in the assembled state, as shown in Fig. 5, both on the top and on the bottom a continuous groove 21 is formed in the manner of a hammer head groove. A contact head 8, which is fastened to the free end of the hanging element 7, is now inserted into the groove 21 from the end face or via notches 22 in the wall-side profile half 18 ', which are distributed at a distance over the length. The contact head 8 here consists of an insulating body 24, in which a support nipple 25 connected to the hanging element 7 and made of electrically conductive material is firmly connected. Since each profile half forms a phase of the profile rail 6 forming the electrical power supply, this ensures that a hanging element 7 can only be connected to one phase of the power supply. Since the contact head 8 is otherwise symmetrical, one of the profile halves can thus be brought into an electrically conductive connection with the hanging element either by appropriate alignment of the insulating body 24.

Die Ausführungsform gern. Fig. 5 zeigt eine Abwandlung, bei der die Profilschienen anstelle von stopfenförmigen Haltekörpern über eine durchgehende Leiste 26 aus einem elektrisch isolierenden Werkstoff gehalten werden. Die Leiste 26 weist eine durchgehende nutenförmige Ausnehmung 27 auf, die im Randbereich mit nach innen gerichteten federnden Randlippen 28 versehen ist. Die Ausnehmung 27 dient hierbei als Kabelkanal, durch die in elektrisch einwandfreier Isolierung gegenüber der durch die Profilhälften 18' und 18'' gebildeten Niederspannungsseite ein Kabel 29 mit beispielsweise 220 Volt-Spannung geführt werden kann. Auf diese Weise ist es ohne Beeinträchtigung der Raumgestaltung möglich, die in Fig. 1 angedeutete Hinteneinanderschaltung von mehreren Niederspannungs-Stromversorgungen 9 und 9' deckenseitig anzuordnen. Jede folgende Niederspannungs-Stromversorgung wird dann gesondert an das Kabel 29 angeschlossen. Zugleich ist es möglich, hiermit die Stromversorgung für andere 220 Volt-Stromverbraucher im Deckenbereich abzugreifen. Der Aufbau entspricht im übrigen dem Aufbau der anhand von Fig. 5 beschriebenen Profilschiene.The embodiment like. Fig. 5 shows a modification in which the rails instead of plug-shaped holding bodies are held by a continuous strip 26 made of an electrically insulating material. The strip 26 has a continuous groove-shaped recess 27 which is provided in the edge region with resilient edge lips 28 directed inwards. The recess 27 serves here as a cable duct through which a cable 29 with, for example, 220 volt voltage can be guided in electrically sound insulation with respect to the low-voltage side formed by the profile halves 18 'and 18' '. In this way, it is possible without affecting the room design to arrange the rear connection of several low-voltage power supplies 9 and 9 'indicated in FIG. 1 on the ceiling. Each subsequent low voltage power supply is then separately connected to the cable 29. At the same time, it is possible to tap the power supply for other 220 volt power consumers in the ceiling area. The structure otherwise corresponds to the structure of the profile rail described with reference to FIG. 5.

In Fig. 6 ist noch einmal in zwei Ansichten der Kontaktkopf 8 eines Hängeelementes 7 dargestellt, um zu verdeutlichen, wie durch unterschiedliches Einhängen in die Profilschiene 6 jeweils unterschiedliche Phasen der Stromversorgung von der Profilschiene 6 abgegriffen werden können.In Fig. 6, the contact head 8 of a hanging element 7 is shown again in two views, to illustrate how different phases of the power supply can be tapped from the profile rail 6 by different hooking into the profile rail 6.

Die Erfindung ist nicht auf die dargestellte und beschriebene Ausführungsfonm der Profilschiene und der damit verbundenen Hängeelemente beschränkt. So ist es beispielsweise möglich, die Profilschiene 6 einstückig aus einem Kunststoff herzustellen, wobei dann lediglich im Bereich der untenliegenden, in Form einer Hammerkopfnut ausgebildeten Ausnehmung 21 entsprechend zwei Kontaktschienen aus Metail mit eingearbeitet sein müssen.The invention is not limited to the illustrated and described embodiment of the profile rail and the associated hanging elements. For example, it is possible to produce the profile rail 6 in one piece from a plastic, in which case two contact rails made of metal need to be incorporated in the area of the recess 21 in the form of a hammer head groove.

Sofern aus Gründen der Raumgestaltung eine metallisch blanke Profilschiene nicht akzeptabel ist, besteht auch die Möglichkeit, die von außen jeweils aufzusetzende Profilhälfte 18'' bereits bei der Herstellung mit einer entsprechenden Abdeckung aus Kunststoff, Holz oder dgl. zu versehen, wobei die Abdeckung auch als Ornamentleiste ausgebildet sein kann. Wie anhand von Fig. 6 dargestellt, kann eine derartige Ornamentleiste 30 auch nachträglich von außen aufgesetzt werden.If, for reasons of interior design, a bare metal profile rail is not acceptable, there is also the possibility of providing the respective profile half 18 '' to be fitted from the outside with a corresponding cover made of plastic, wood or the like during manufacture, the cover also being able to be designed as an ornamental strip. As shown in FIG. 6, such an ornamental strip 30 can also be retrofitted from the outside.

Die Profilschienen 6 sind zweckmäßig zumindest an einem Ende mit Steckkontakten versehen, so daß die elektrische Verbindung mit der Stromversorgung, aber auch mit einer anschließenden Profilschiene durch einfaches Zusammenstecken erfolgen kann. Für den Bereich von Raumecken sind entsprechend ausgebildete Eckverbinder zweckmäßig.The profile rails 6 are expediently provided with plug contacts at least at one end, so that the electrical connection to the power supply, but also to a subsequent profile rail, can be made by simply plugging them together. Appropriate trained corner connectors are appropriate for the area of room corners.
