The invention achieves the object of providing a suspension system which is suitable for optional mounting on a ceiling hook (14) or directly on the ceiling (11). The invention provides a suspension frame (15) which has a mounting plate (19) that is to be fastened directly to the ceiling. Below the mounting plate (19) is a vertical eyelet (25) into which a ceiling hook (14) can be placed. The eyelet (25) is bounded by a retaining ring (22), into which a rod (17) on which the lamp hangs can be screwed. As an alternative to the rod (17), it is possible to use a cable which extends through bores (29) of the suspension frame (19) and has two pendant sections on which the lamp housing with the housing holder can be mounted. <IMAGE>

Description

Die Erfindung betrifft eine Aufhängevorrichtung für eine Hängeleuchte nach dem Oberbegriff des Patentanspruchs 1 bzw. einen Aufhängebügel für eine Hängeleuchte nach dem Oberbegriff des Patentauspruchs 16.The invention relates to a hanging device for a hanging lamp according to the preamble of claim 1 and a hanging bracket for a hanging lamp according to the preamble of patent claim 16.

Es ist bekannt, Hänge- oder Pendelleuchten an der Decke entweder an Haken oder an einer an der Decke zu befestigenden Halterung zu montieren. Bei Verwendung eines Deckenhakens kann sich zwischen dem in den Deckenhaken eingesetzten Aufhängebügel und dem unteren Gehäusehalter ein starrer rohrförmiger Pendelstab erstrecken, durch den das Leuchtenkabel geführt wird. Wenn an der Decke ein starrer Haltebügel befestigt wird, können zwischen diesem Haltebügel und dem Gehäuse Seile verlaufen, an denen das Leuchtengehäuse aufgehängt ist. Die beiden Befestigungsarten mit Pendelstab und Seilen erfordern unterschiedliche obere und untere Halterungen, so daß einer Pendelleuchte, die für beide Befestigungsarten wahlweise vorgesehen ist, jeweils ein kompletter Satz der beiden verschiedenartigen Aufhängevorrichtungen beigegeben werden muß. Wenn andererseits dasselbe Leuchtengehäuse jeweils nur mit einer bestimmten Aufhängevorrichtung für Hakenaufhängung oder Pendelstabaufhängung vorgesehen ist, wird dadurch die vom Leuchtenhersteller bereitzuhaltende Typenvielfalt erhöht.It is known to mount hanging or pendant lights on the ceiling either on hooks or on a bracket to be attached to the ceiling. When using a ceiling hook, a rigid tubular pendulum rod can extend between the hanging bracket inserted in the ceiling hook and the lower housing holder, through which the lamp cable is guided. If a rigid bracket is attached to the ceiling, ropes can run between this bracket and the housing, on which the lamp housing is suspended. The two types of attachment with pendulum rod and ropes require different upper and lower brackets, so that a pendant lamp, which is optionally provided for both types of attachment, each a complete set of the two different types of suspension devices must be added. If on the other hand the same luminaire housing is only provided with a specific suspension device for hook suspension or pendulum rod suspension, this increases the variety of types to be provided by the luminaire manufacturer.

Die Oberbegriffe der Patentansprüche 1 und 16 gehen aus von einer Aufhängevorrichtung bzw. einem Aufhängebügel für eine Hängeleuchte nach US-A-2 739 780. Hierbei ist ein Aufhängebügel vorgesehen, der eine unmittelbar unter einer Decke zu befestigende Montageplatte und mit Abstand unterhalb der Montageplatte einen Haltering aufweist. In den Haltering ist eine schwenkbare Gelenkkugel eingesetzt, von der ein Stab, an dem das Leuchtengehäuse befestigt ist, herabhängt. Die Gelenkkugel weist eine Öse für das seitliche Einschieben des oberen Endes des Stabes auf. Sie ermöglicht die pendelnde Aufhängung des Leuchtengehäuses, ist jedoch wegen des Kugelgelenks aufwendig.The preambles of claims 1 and 16 are based on a suspension device or a suspension bracket for a hanging lamp according to US-A-2 739 780. Here, a suspension bracket is provided which is a mounting plate to be fastened directly under a ceiling and a distance below the mounting plate Has retaining ring. A pivotable joint ball is inserted into the retaining ring, from which a rod to which the lamp housing is attached hangs. The joint ball has an eyelet for the lateral insertion of the upper end of the rod. It enables the lamp housing to be suspended, but is expensive due to the ball joint.

Aus US-A-2 990 153 ist ein Aufhängebügel bekannt, der ebenfalls eine an der Decke zu befestigende Montageplatte und unterhalb dieser einen Haltering aufweist. In den Haltering wird eine Schraube eingeschraubt, die einen Blendendeckel festhält und den Durchtritt des das Leuchtengehäuse haltenden Kabels ermöglicht. Ein derartiger Aufhängebügel ist ebenfalls ausschließlich für die unmittelbare Montage an einer Decke oder einer anderen Haltevorrichtung geeignet und nur für die Verwendung eines elektrischen Kabels als Aufhängevorrichtung für das Leuchtengehäuse vorgesehen.From US-A-2 990 153 a suspension bracket is known which also has a mounting plate to be fastened to the ceiling and below this a retaining ring. A screw is screwed into the retaining ring, which holds a cover lid and allows the cable holding the lamp housing to pass through. Such a suspension bracket is also only suitable for direct mounting on a ceiling or other holding device and is only intended for the use of an electrical cable as a suspension device for the lamp housing.

Aus US-A-1 680 078 ist ein Leuchtengehäuse bekannt, das an einen Aufhängebügel unmittelbar angeschraubt wird und diesen seitlich umschließt und somit unmittelbar an die Decke anschließt. Das Leuchtengehäuse weist an seinem Umfang eine Öse für den Durchtritt des elektrischen Zuleitungskabels auf.From US-A-1 680 078 a luminaire housing is known which is screwed directly onto a suspension bracket and encloses it laterally and thus directly on the ceiling connects. The circumference of the lamp housing has an eyelet for the passage of the electrical supply cable.

DE-U-8 518 629 beschreibt eine Hängeleuchte mit einem Aufhängebügel, von dem ein das Leuchtengehäuse haltendes Seil herabhängt. Der Haltebügel ist von einer Schutzkappe umgeben, die Durchtrittsöffnungen für das Leuchtenkabel und die beiden Züge des Seiles aufweist. Der Aufhängebügel ist ausschließlich für die direkte Deckenmontage und für die Seilaufhängung des Leuchtengehäuses geeignet.DE-U-8 518 629 describes a hanging lamp with a hanging bracket from which a rope holding the lamp housing hangs. The bracket is surrounded by a protective cap that has openings for the lamp cable and the two cables. The suspension bracket is only suitable for direct ceiling mounting and for rope suspension of the luminaire housing.

GB-A-1 515 400 beschreibt einen Aufhängebügel für die direkte Deckenmontage, wobei zwischen Montageplatte und Decke Pufferelemente vorgesehen sind.GB-A-1 515 400 describes a suspension bracket for direct ceiling mounting, buffer elements being provided between the mounting plate and the ceiling.

Bei einer Deckenleuchte nach FR-E-43 193 ist ein Aufhängebügel mit federnden Schenkeln versehen, die die Leuchtenschale festhalten.In the case of a ceiling light according to FR-E-43 193, a hanging bracket is provided with resilient legs that hold the light shell in place.

DE-C-820 262 beschreibt einen Leuchtenhalter mit einem pendelnd aufgehängten Stab, dessen unteres Ende die einander zugewandten Enden zweier Leuchtstofflampen trägt.DE-C-820 262 describes a lamp holder with a pendulum-suspended rod, the lower end of which supports the mutually facing ends of two fluorescent lamps.

Der Erfindung liegt die Aufgabe zugrunde, eine Aufhängevorrichtung bzw. einen Aufhängebügel für eine Hängeleuchte zu schaffen, die sowohl für Hakenaufhängung, als auch für die direkte starre Deckenbefestigung geeignet sind, ohne daß sämtliche Bestandteile in doppelter Ausführung vorgesehen sein müßten.The invention has for its object to provide a suspension device or a suspension bracket for a hanging lamp, which are suitable both for hook suspension, as well as for the direct rigid ceiling mounting, without all the components would have to be provided in duplicate.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 bzw. mit den Merkmalen des Patentanspruchs 16.This object is achieved according to the invention with the features of patent claim 1 or with the features of patent claim 16.

Bei der erfindungsgemäßen Aufhängevorrichtung ist der Aufhängebügel so ausgebildet, daß er wahlweise mit der Öse in einen Deckenhaken lose eingehängt oder mit der Montageplatte unmittelbar flach an der Decke anliegend starr mit der Decke befestigt werden kann. Der Aufhängebügel weist eine obere Montageplatte auf, die von unten her gegen die Decke gesetzt und mit dieser verschraubt werden kann. Unter der Montageplatte ist eine Öse vorgesehen, durch die hindurch an der Montageplatte vorbei der Haken geführt werden kann. Bei der Hakenbefestigung hängt der Aufhängebügel in vertikalem Abstand unter der Decke, wobei die Montageplatte unbenutzt ist. An dem Haltering, der das untere Ende der Öse bildet, kann ein Stab befestigt werden, der senkrecht von dem Aufhängebügel herabhängt und an dessem unteren Ende das Leuchtengehäuse befestigt wird. Bei Verwendung eines derartigen Stabes, der starr mit dem Aufhängebügel verbunden wird, sollte der Aufhängebügel pendelnd an einem Haken befestigt sein. Prinzipiell ist es zwar auch möglich, in dem Fall, daß der Aufhänge bügel unmittelbar an der Decke befestigt ist, einen starren Stab anzubringen, jedoch besteht dann die Gefahr, daß infolge der langen Hebelwirkung des Stabes bei Bewegungen des Leuchtengehäuses die Deckenbefestigung des Aufhängebügels ausreißt. Bei direkter Deckenbefestigung des Aufhängebügels sollte die Leuchtenaufhängung nicht mit einem starren Stab, sondern mit einem Seil erfolgen, das Leuchtenbewegungen zuläßt, ohne ein Moment auf den Aufhängebügel auszuüben.In the suspension device according to the invention, the suspension bracket is designed such that it can either be loosely hung in a ceiling hook with the eyelet or rigidly attached to the ceiling with the mounting plate lying flat against the ceiling. The suspension bracket has an upper mounting plate that can be placed against the ceiling from below and screwed to it. An eyelet is provided under the mounting plate, through which the hook can be guided past the mounting plate. When attaching the hook, the suspension bracket hangs vertically below the ceiling, whereby the mounting plate is not used. A rod can be attached to the retaining ring, which forms the lower end of the eyelet, which hangs vertically from the suspension bracket and the luminaire housing is attached to its lower end. At Using such a rod, which is rigidly connected to the suspension bracket, the suspension bracket should be attached to a hook in a swinging manner. In principle, it is also possible to attach a rigid rod in the event that the suspension bracket is attached directly to the ceiling, but then there is a risk that due to the long lever action of the rod when the lamp housing moves, the ceiling mounting of the suspension bracket will tear away. If the suspension bracket is directly attached to the ceiling, the luminaire should not be suspended with a rigid rod, but with a rope that allows the luminaire to move without exerting a moment on the suspension bracket.

Der Aufhängebügel kann entweder Bestandteil einer der Leuchte vom Hersteller beigegebenen vielseitig verwendbaren Aufhängevorrichtung sein, bei der bei Wahl einer bestimmten Aufhängeart nicht sämtliche Komponenten benutzt werden. Andererseits ist es auch möglich, den Aufhängebügel separat für eine Vielzahl von Leuchten, unabhängig davon, für welche Befestigungsart diese Leuchten ausgebildet sind, separat zu liefern. Der Aufhängebügel, der wahlweise für die Hakenbefestigung und für die direkte Deckenmontage geeignet ist, bildet in allgemeinster Form ein separates Aufhängeteil, das unabhängig von der speziellen Ausbildung des leuchtenseitigen Gehäusehalters verwendbar ist.The suspension bracket can either be part of a versatile suspension device provided by the manufacturer, in which not all components are used when a particular suspension type is selected. On the other hand, it is also possible to supply the suspension bracket separately for a large number of lights, regardless of the type of fastening for which these lights are designed. The hanging bracket, which is optionally suitable for hook mounting and for direct ceiling mounting, forms a separate hanging part in the most general form, which can be used regardless of the special design of the luminaire-side housing holder.

Grundsätzlich kann die Montageplatte so schmal sein, daß sie das Einsetzen des Deckenhakens in die Öse nicht behindert. Zweckmäßigerweise hat die Montageplatte jedoch eine größere Breite, wobei die Merkmale des Anspruchs 2 vorgesehen sind, um ein ungehindertes Einsetzen des Hakens und ein Pendeln des Aufhängebügels zu ermöglichen.Basically, the mounting plate can be so narrow that it does not hinder the insertion of the ceiling hook into the eyelet. Expediently, however, the mounting plate has a larger width, the features of claim 2 being provided in order to enable unimpeded insertion of the hook and an oscillation of the suspension bracket.

Die Merkmale der Ansprüche 3 und 4 ermöglichen die Verwendung eines Seiles als Zugorgan, wobei ein einziges Seil mit zwei im wesentlichen parallelen Abschnitten die Verbindung zwischen dem Aufhängebügel und dem Gehäusehalter herstellt. Die Längen der beiden im Aufhängebügel miteinander verbundenen Seilabschnitte können durch Verschiebung des Seils in Bezug auf den Aufhängebügel variiert werden. Durch die im Aufhängebügel vorgesehene Nut zwischen den Bohrungen wird erreicht, daß der Umlenkbereich des Seiles nicht zwischen Montageplatte und Decke festgeklemmt wird, so daß das Seil auch bei montiertem Aufhängebügel längenmäßig justierbar ist.The features of claims 3 and 4 enable the use of a rope as a tension member, a single rope with two substantially parallel sections establishing the connection between the suspension bracket and the housing holder. The lengths of the two rope sections connected to one another in the suspension bracket can be varied by moving the rope in relation to the suspension bracket. The groove provided in the suspension bracket between the holes ensures that the deflection area of the rope is not clamped between the mounting plate and the ceiling, so that the rope can be adjusted in length even when the suspension bracket is installed.

Der Aufhängebügel, der vorzugsweise aus Metall besteht, kann auf relativ einfache Weise geerdet werden, wodurch die an ihm befestigte Stange oder das aus Draht bestehende Seil ebenfalls geerdet wird. Wenn von dem Aufhängebügel ein elektrisches Kabel zu dem Gehäusehalter führt, sollte in dem Fall, daß das Kabel ungeschützt verläuft, eine Zugentlastung für das Kabel vorgesehen sein. Ein Zugentlastungsteil kann an dem Haltering, der sonst für die Befestigung der Stange dient, angebracht werden.The suspension bracket, which is preferably made of metal, can be grounded in a relatively simple manner, as a result of which the rod or rope attached to it is also grounded. If an electrical cable leads from the suspension bracket to the housing holder, a strain relief for the cable should be provided in the event that the cable runs unprotected. A strain relief part can be attached to the retaining ring, which is otherwise used to attach the rod.

Gemäß Fig. 1 ist eine Hängeleuchte 10 mit zwei Aufhängevorrichtungen an der Decke 11 aufgehängt, wobei nur die eine Aufhängevorrichtung 12 dargestellt ist. Beide Aufhängevorrichtungen greifen an den stirnseitigen Enden des langgestreckten Leuchtengehäuses 13 an, und zwar außerhalb des Bereichs, der von den im Innern des Leuchtengehäuses 13 vorgesehenen Lampenfassungen begrenzt wird.1, a hanging lamp 10 with two suspension devices is suspended from the ceiling 11, only one suspension device 12 being shown. Both suspension devices grip at the front ends of the elongated luminaire housing 13, specifically outside the area which is delimited by the lamp sockets provided in the interior of the luminaire housing 13.

An der Decke 11 ist in üblicher Weise ein Deckenhaken 14 befestigt, in den der Aufhängebügel 15 eingehängt ist. Bei der in den Fign. 1 bis 7 dargestellten Aufhängeart erstreckt sich zwischen dem Aufhängebügel 15 und dem am Leuchtengehäuse 13 befestigten Gehäusehalter 16 ein rohrförmiger Stab 17, durch den hindurch ein Kabel 18 zum elektrischen Verbinden der Leuchte mit einem (nicht dargestellten) Deckenanschluß in der Nähe des Hakens 14 verläuft.In the usual way, a ceiling hook 14 is attached to the ceiling 11, in which the suspension bracket 15 is suspended. In the case of the figures 1 to 7 shown hanging type extends between the suspension bracket 15 and the housing holder 16 attached to the lamp housing 13, a tubular rod 17 through which a cable 18 for electrically connecting the lamp with a (not shown) ceiling connection in the vicinity of the hook 14 extends.

Der Aufhängebügel 15 weist eine plane obere Montageplatte 19 auf, unter der sich ein rechtwinklig nach unten abstehender Steg 20 erstreckt. Von dem Steg 20 ragen zwei Arme 21 nach unten. Die unteren Enden der Arme 21 sind durch den Haltering 22, dessen Ringebene parallel zur Ebene der Montageplatte 19 verläuft, miteinander verbunden. Der Haltering 22 ist mit einem Innengewinde 23 versehen, in das ein am oberen Ende des Stabes 17 vorgesehenes Außengewinde 24 (Fign. 2 und 3) eingeschraubt werden kann.The suspension bracket 15 has a flat upper mounting plate 19, under which a web 20 protruding downwards at right angles extends. Two arms 21 project downward from the web 20. The lower ends of the arms 21 are connected to one another by the retaining ring 22, the ring plane of which extends parallel to the plane of the mounting plate 19. The retaining ring 22 is provided with an internal thread 23 into which an external thread 24 (FIGS. 2 and 3) provided at the upper end of the rod 17 can be screwed.

Der horizontale Steg 20 bildet zusammen mit den Armen 21 und dem Haltering 22 eine Öse 25 zum Hindurchstecken des Hakens 14. Die obere Begrenzung der Öse 25 hat die Form eines umgekehrten V, dessen beide Flanken in der Mitte der Länge des Haltebügels zusammenlaufen, so daß der Haltebügel 15 an dem Haken 14 selbstzentrierend ist.The horizontal web 20 forms, together with the arms 21 and the retaining ring 22, an eyelet 25 for the insertion of the hook 14. The upper limit of the eyelet 25 has the shape of an inverted V, the two flanks of which converge in the middle of the length of the holding bracket, so that the bracket 15 on the hook 14 is self-centering.

Die Montageplatte 19 ist im Mittelbereich ihrer Länge mit zwei seitlichen Aussparungen 26 versehen, deren Tiefe so groß ist, daß die Breite der Halteplatte 19 im Mittelbereich auf die Breite des Steges 20 reduziert ist. Die trapezförmigen Aussparungen 26 dienen dazu, das Einsetzen des Hakens 14 in die Öse 25 zu erleichtern und im eingesetzten Zustand Pendelbewegungen des Aufhängebügels 15 in Bezug auf den Haken 14 zu ermöglichen.The mounting plate 19 is provided in the central region of its length with two lateral recesses 26, the depth of which is so great that the width of the holding plate 19 is reduced to the width of the web 20 in the central region. The trapezoidal recesses 26 serve to facilitate the insertion of the hook 14 into the eyelet 25 and to enable pendulum movements of the suspension bracket 15 in relation to the hook 14 in the inserted state.

In der Montageplatte 19 sind querlaufende Langlöcher 27 vorgesehen, um die direkte Deckenmontage des Aufhängebügels 15 mit Schrauben durchführen zu können. Bei der Hakenmontage werden die Langlöcher 27 dazu benutzt, säulenförmige Pufferelemente 28 aus Gummi anzubringen, die von der Halteplatte 19 aufragen. Die elastischen Pufferelemente 28 ragen gemäß Fig. 2 bis in die Nähe der Decke 11 und dienen dazu, Pendelbewegungen des Aufhängebügels 15 zu begrenzen und zu dämpfen.Transversely extending slots 27 are provided in the mounting plate 19 in order to be able to carry out the direct ceiling mounting of the suspension bracket 15 with screws. During the hook assembly, the elongated holes 27 are used to attach columnar rubber buffer elements 28 which protrude from the holding plate 19. 2 extend into the vicinity of the ceiling 11 and serve to limit and dampen pendulum movements of the suspension bracket 15.

Durch die Montageplatte 19 und den Steg 20 verlaufen vertikale Bohrungen 29, in die im Bereich des Steges 20 querlaufende Gewindebohrungen 30 einmünden. In die Gewindebohrungen 30 sind Klemmschrauben 31 eingeschraubt, um ein durch die Bohrungen 29 gezogenes Seil festzuklemmen. In der Oberseite der Montageplatte 19 verläuft eine Nut 32, die die oberen Enden der Bohrungen 29 miteinander verbindet.Vertical bores 29 run through the mounting plate 19 and the web 20, into which transverse threaded bores 30 open in the region of the web 20. Clamping screws 31 are screwed into the threaded bores 30 in order to clamp a rope pulled through the bores 29. A groove 32 runs in the upper side of the mounting plate 19 and connects the upper ends of the bores 29 to one another.

Von den Enden der Montageplatte 19 ragen Klemmschenkel 33, die außen mit einer Riffelung versehen sind, nach unten. Wenn eine aus Kunststoff bestehende Schutzkappe 34, die eine Durchgangsöffnung 35 für den Stab 17 aufweist, von unten her auf den Aufhängelbügel 15 aufgeschoben wird, spreizen die Klemmschenkel 33 die Schutzkappe 34 geringfügig auseinander, so daß die Schutzkappe klemmend an dem Aufhängebügel 15 festgehalten wird. Die Schutzkappe kann dabei so weit auf den Aufhängebügel aufgeschoben werden, bis ihr oberes Ende gegen die Decke 11 stößt. Die Klemmschenkel 33 halten die Schutzkappe 34 unabhängig davon fest, wie weit diese Schutzkappe über den Aufhängebügel geschoben ist, bzw. wie weit der Aufhängebügel 15 in die Schutzkappe eintaucht.From the ends of the mounting plate 19, clamping legs 33, which are provided with corrugations on the outside, project downward. If a protective cap 34 made of plastic, which has a through opening 35 for the rod 17, is pushed onto the suspension bracket 15 from below, the clamping limbs 33 spread the protective cap 34 slightly apart, so that the protective cap is held clamped to the suspension bracket 15. The protective cap can be pushed onto the suspension bracket until its upper end abuts the ceiling 11. The clamping legs 33 hold the protective cap 34 in place regardless of how far this protective cap is pushed over the suspension bracket or how far the suspension bracket 15 plunges into the protection cap.

Neben den Gewindebohrungen 30 sind an dem Steg 20 Kontaktelemente 36 in Form von in Gewindebohrungen eingeschraubten Schrauben vorgesehen. Diese Kontaktelemente 36 können mit Masse- oder Erdleitungen verbunden werden, um den Aufhängebügel und die damit verbundenen elektrisch leitenden Teile zu erden.In addition to the threaded bores 30, contact elements 36 in the form of screws screwed into threaded bores are provided on the web 20. These contact elements 36 can be connected to earth or ground lines in order to ground the suspension bracket and the electrically conductive parts connected to it.

Der beschriebene Aufhängebügel besteht (mit Ausnahme der in ihn eingesetzten Schrauben) aus einem einstückigen Metallteil, das beispielsweise im Druckgußverfahren hergestellt werden kann.The suspension bracket described consists (with the exception of the screws inserted in it) from a one-piece metal part which can be produced, for example, by the die-casting process.

Der am unteren Ende der Stange 17 befestigte Gehäusehalter 16 besteht aus einem metallischen Block 40, der von innen her in einen Ausschnitt 41 der Stirnwand des Gehäuses 13 eingesetzt ist und einen Rand 42 aufweist, welcher nicht durch die Gehäuseöffnung 41 hindurchpaßt und somit ein Auflager für den Rand der Gehäuseöffnung bildet. Der durch die Gehäuseöffnung 41 hindurchragende Ansatz 46 des Blockes 16 enthält eine Gewindebohrung 47, in die ein am unteren Ende der Stange 17 vorgesehenes Gewinde 48 eingeschraubt werden kann.The attached to the lower end of the rod 17 housing holder 16 consists of a metallic block 40 which is inserted from the inside into a cutout 41 of the end wall of the housing 13 and has an edge 42 which does not fit through the housing opening 41 and thus a support for forms the edge of the housing opening. The projection 46 of the block 16 projecting through the housing opening 41 contains a threaded bore 47 into which a thread 48 provided at the lower end of the rod 17 can be screwed.

Am unteren Ende des Ansatzes 46 befindet sich ein kleiner Vorsprung 49 bzw. eine Hinterschneidung, die sich an dem Rand der Gehäuseöffnung 41 verhakt. An der dem Vorsprung 49 gegenüberliegenden Seite ist der Block 40 mit zwei elastischen Puffern 50 versehen, die geringfügig abstehen und gegen eine Innenwand 51 des Gehäuses 13 drücken. An dieser Innenwand 51 sind auch die (nicht dargestellten) Lampenfassungen befestigt. Durch die elastischen Puffer 50 wird der Block 40 mit seinem Vorsprung 49 nach außen über den Rand der Gehäuseöffnung 41 gedrückt, so daß er an dem Gehäuse 13 einen Halt erhält und nicht unbeabsichtigt in das Gehäuse hineinfallen kann. Der Block 40 ist also nur lose von innen her in das Gehäuse 13 eingesetzt und an der Gehäusewand festgeklemmt. Das Lösen des Blocks 40 erfolgt dadurch, daß dieser Block in Richtung auf die Wand 51 gedrückt wird, wodurch der Vorsprung 49 von dem Rand der Gehäuseöffnung 41 freikommt, so daß der Block 40 anschließend in das Gehäuseinnere hinein abgesenkt werden kann. Umgekehrt erfolgt die Montage des Blocks 40 in der in Fig. 5 dargestellten Weise vom Gehäuseinneren her.At the lower end of the extension 46 there is a small projection 49 or an undercut which hooks on the edge of the housing opening 41. At the block 40 is provided with protrusion 49 with two elastic buffers 50 which protrude slightly and press against an inner wall 51 of housing 13. The lamp holders (not shown) are also fastened to this inner wall 51. By means of the elastic buffers 50, the block 40 with its projection 49 is pressed outward over the edge of the housing opening 41, so that it receives a hold on the housing 13 and cannot accidentally fall into the housing. The block 40 is therefore only loosely inserted from the inside into the housing 13 and clamped onto the housing wall. The block 40 is released by pressing this block in the direction of the wall 51, as a result of which the projection 49 is released from the edge of the housing opening 41, so that the block 40 can subsequently be lowered into the interior of the housing. Conversely, the block 40 is assembled in the manner shown in FIG. 5 from the inside of the housing.

Unterhalb der Durchgangsöffnung 47 befindet sich im Block 40 ein Hohlraum 52, in den die Durchgangsbohrung 47 mündet und in dem eine Klemmvorrichtung 53 angebracht ist, um ein durch die Durchgangsöffnung 47 verlaufendes Kabel 18 zum Zwecke der Zugentlastung am Block 40 festklemmen zu können.Below the through opening 47 there is a cavity 52 in the block 40, into which the through hole 47 opens and in which a clamping device 53 is attached in order to be able to clamp a cable 18 running through the through opening 47 to the block 40 for the purpose of strain relief.

Durch die gesamte Höhe des Blocks 40 erstrecken sich zu beiden Seiten der Durchgangsöffnung 47 Seildurchgangsbohrungen 54, in die im Innern des Gehäuses Querbohrungen mit Klemmschrauben 55 münden. Die Klemmschrauben 55 dienen zum Festlegen der durch die Seildurchgangsbohrungen 54 hindurchgeführten Seilabschnitte. Die Köpfe der Klemmschrauben 55 sind, ebenso wie die Köpfe der Schrauben der Klemmvorrichtung 53, zum Gehäuseinnern gewandt, so daß sämtliche Schrauben des Gehäusehalters vom Gehäuseinnern her zugänglich sind. Das Ausrichten bzw. die Höheneinstellung kann daher bei in das Leuchtengehäuse eingesetztem Gehäusehalter 16 erfolgen, wenn beispielsweise die untere Lampenabdeckung aus dem Leuchtengehäuse entfernt ist.Through the entire height of the block 40, rope through bores 54 extend on both sides of the through opening 47, into which cross bores with clamping screws 55 open in the interior of the housing. The clamping screws 55 are used to fix the rope sections passed through the rope through holes 54. The heads of the clamping screws 55, like the heads of the screws of the clamping device 53, face the inside of the housing, so that all the screws of the housing holder are accessible from the inside of the housing. Alignment or height adjustment can therefore take place with the housing holder 16 inserted into the luminaire housing, for example if the lower lamp cover is removed from the luminaire housing.

Während bei der in den Fign. 1 bis 7 dargestellten Benutzungsart der Aufhängevorrichtung Stangen 17 verwendet werden, ist in den Fign. 8 und 9 eine Benutzungsart dargestellt, bei der die Leuchte mit einem Seil 60 an dem Aufhängebügel 15 aufgehängt ist. Es ist ein einziges Seil 60 vorhanden, dessen beide Endbereiche an dem Block 40 mit den Klemmschrauben 55 festgelegt sind. Die Seilenden ragen aus dem unteren Ende des Blocks 40 heraus in das Leuchtengehäuse 13 hinein. Die Seildurchgangsbohrungen 54 im Gehäusehalter 16 haben den gleichen gegenseitigen Abstand wie die Bohrungen 29 im Aufhängebügel 15. Zu beiden Seiten der Durchgangsöffnung 35 sind im Boden der Schutzkappe 34 Seilöffnungen 61 vorgesehen, die ebenfalls den Abstand der Bohrungen 29 haben. Das Seil 60 führt also von einer Seildurchgangsbohrung 54 aus in die Schutzkappe 34 hinein, durch eine Bohrung 29, anschließend an der Oberseite der Montageplatte 15 in der Nut 32 zur anderen Bohrung 29 und von dort wieder durch die Schutzkappe 34 hindurch zurück zum Gehäusehalter 16. Die Klemmschrauben 31 im Aufhängebügel 15 ermöglichen die Fixierung des Seils 60 in der Weise, daß ein späteres Schiefhängen der Leuchte 10 verhindert wird. Bei der in den Fign. 8 und 9 dargestellten Aufhängeart ist das elektrische Kabel mit einem Zugentlastungsteil 62 am Haltering 22 des Aufhängebügels 15 befestigt. Das Zugentlastungsteil 62 besteht aus einer Gewindebuchse, die in das Gewinde des Halterings 22 eingeschraubt ist und eine Klemmvorrichtung 63 in Form einer Klemmschraube zum Festklemmen des Kabels 18 aufweist. Das Kabel 18 führt durch die Durchgangsöffnung 35 der Schutzkappe 34 hindurch nach unten, ragt durch die Durchgangsöffnung 47 des Gehäusehalters 16 hindurch und ist im Gehäusehalter 16 mit der Klemmvorrichtung 53 fixiert.While in the figures 1 to 7 shown use of the suspension device rods 17 is used in Figs. 8 and 9 show a type of use in which the lamp is suspended from the suspension bracket 15 with a rope 60. There is a single rope 60, the two end regions of which are fixed to the block 40 with the clamping screws 55. The cable ends protrude from the lower end of the block 40 into the lamp housing 13. The rope through holes 54 in the housing holder 16 are at the same mutual distance as the holes 29 in the suspension bracket 15. On both sides of the through opening 35, rope openings 61 are provided in the bottom of the protective cap 34, which are also at a distance from the holes 29. The rope 60 thus leads from a rope through bore 54 into the protective cap 34, through a bore 29, then at the top of the mounting plate 15 in the groove 32 to the other bore 29 and from there through the protective cap 34 back to the housing holder 16. The clamping screws 31 in the suspension bracket 15 enable the rope 60 to be fixed in such a way that the lamp 10 is prevented from laterally sloping. In the case of the figures 8 and 9 shown suspension type, the electrical cable is fastened with a strain relief part 62 to the retaining ring 22 of the suspension bracket 15. The strain relief part 62 consists of a threaded bush which is screwed into the thread of the retaining ring 22 and a clamping device 63 in the form of a clamping screw for clamping the Cable 18 has. The cable 18 leads down through the through opening 35 of the protective cap 34, projects through the through opening 47 of the housing holder 16 and is fixed in the housing holder 16 with the clamping device 53.

Bei der zuletzt beschriebenen Befestigungsart wird der Aufhängebügel 15 mit der Montageplatte 19 direkt unter die Decke 11 gesetzt und mit Schrauben, die durch die Löcher 27 hindurchgehen, an der Decke befestigt. Die Schutzkappe 34 wird über die Klemmschenkel 33 geschoben, die in diesem Fall in der Nähe des oberen Randes an der Seitenwand der Schutzkappe 34 angreifen.In the type of fastening described last, the suspension bracket 15 with the mounting plate 19 is placed directly under the ceiling 11 and fastened to the ceiling with screws that pass through the holes 27. The protective cap 34 is pushed over the clamping legs 33, which in this case engage near the upper edge on the side wall of the protective cap 34.

Bei der beschriebenen Aufhängevorrichtung sind der Aufhängebügel 15, die Schutzkappe 34 und der Gehäusehalter 16 bei beiden Aufhängearten gleichermaßen verwendbar. Lediglich die Stange 17, das Drahtseil 60 und das Zugentlastungsteil 62 sind Teile, die jeweils bei einer bestimmten Aufhängeart wahlweise benutzt werden. Diese wahlweise zu benutzenden Teile sind relativ einfach, so daß ihre Herstellung keine großen Kosten verursacht und durch ihre Nichtbenutzung kein wesentlicher Mehraufwand besteht.In the suspension device described, the suspension bracket 15, the protective cap 34 and the housing holder 16 can be used equally with both suspension types. Only the rod 17, the wire cable 60 and the strain relief part 62 are parts which are each optionally used in a specific type of suspension. These optional parts are relatively simple, so that their production does not cause great costs and there is no significant additional effort due to their non-use.
