Description

Die Erfindung betrifft eine Leuchte, vorzugsweise eine Deckeneinbauleuchte, gemäß dem Oberbegriff des Anspruches 1.The invention relates to a lamp, preferably a recessed ceiling lamp, according to the preamble of claim 1.

Bei einer bekannten Leuchte dieser Art (DE-U 7 522 285) wird eine Leuchtenabdeckung mittels zweischenkligen Federdrahtbügeln am Leuchtengehäuse gehalten, indem diese Federdrahtbügel am Leuchtengehäuse angeordnete Kulissen durchdringen und in der Betriebsstellung der Abdeckung mit den Kulissen verrastet sind. Die Schenkel der Federdrahtbügel haben obenseitig hakenförmige Abwinklungen, derart, daß, wenn man die Leuchtenabdeckung unter Überwindung der von den Federdrahtbügeln ausgeübten Rastkräfte nach unten zieht, dann diese hakenförmigen Enden der Federdrahtbügel seitlich auf die Kulissen zum Aufliegen kommen und so dann die Abdeckung in ihrer abgehängten Stellung halten. Aus dieser abgehängten Stellung kann die Abdeckung abgeklappt werden, indem man die Federdrahtbügel an einer Seite des Leuchtengehäuses aus den Kulissen aushängt.In a known luminaire of this type (DE-U 7 522 285), a luminaire cover is held on the luminaire housing by means of two-leg spring wire clips, in that these spring wire clips penetrate baffles arranged on the luminaire housing and are locked with the baffles in the operating position of the cover. The legs of the spring wire bracket have hook-shaped bends on the top, such that when the lamp cover is overcome by overcoming the Spring wire brackets exerted locking forces pulls down, then these hook-shaped ends of the spring wire bracket come to rest laterally on the scenes and so then hold the cover in its suspended position. From this suspended position, the cover can be folded down by unhooking the spring wire bracket on one side of the lamp housing.

An eine sichere Schutzleiterverbindung zwischen der Abdeckung und dem Leuchtengehäuse ist nicht gedacht. Auch ist das manuelle Einsetzen der Federbügel in die Schlitze der Kulissen schwierig und nicht ohne weiteres von einer einzigen Person ausführbar. Auch ist die Tragkraft solcher Federdrahtbügel in ihren verrasteten Stellungen nicht bedeutend, wenn sie so schwach ausgebildet werden, daß eine nur relativ wenig Kraft erfordernde manuelle Bedienung von ihnen möglich sein soll.A secure protective conductor connection between the cover and the luminaire housing is not intended. The manual insertion of the spring clip into the slots of the scenes is difficult and cannot be carried out easily by a single person. Also, the load-bearing capacity of such spring wire clips in their locked positions is not significant if they are so weakly designed that manual operation of them which requires relatively little force should be possible.

Es ist eine Aufgabe der Erfindung, eine Leuchte der im Oberbegriff des Anspruches 1 genannten Art zu schaffen, welche sichere elektrische Schutzleiterverbindung zwischen dem Raster und dem Leuchtengehäuse über die Abhängevorrichtung ermöglicht, die ferner im Innenraum des Leuchtengehäuses angeordnet werden kann und die einfache Bedienung und sichere Verrastung zuläßt, die selbst ungeübten Personen keine Probleme zu bereiten braucht.It is an object of the invention to provide a luminaire of the type mentioned in the preamble of claim 1, which enables safe electrical protective conductor connection between the grid and the luminaire housing via the suspension device, which also in the interior of the Luminaire housing can be arranged and allows easy operation and secure locking that even inexperienced people need not cause any problems.

Diese Aufgabe wird erfindungsgemäß durch die in Anspruch 1 angegebene Leuchte gelöst.This object is achieved by the lamp specified in claim 1.

Bei dieser erfindungsgemäßen Leuchte ergibt sich eine auch unter schwierigen Bedingungen sichere elektrische Schutzleiterverbindung zwischen dem Raster und dem Leuchtengehäuse über die Abhängevorrichtungen. Die Abhängevorrichtungen sind baulich einfach und eignen sich für kostengünstige Herstellung und schnelle, leichte Montage. Auch kann man sie ohne weiteres so ausbilden, daß sie selbst bei hohen Rastkräften nur wenig Kraft zum Einsetzen der Träger in die Druckfederteile benötigen. Indemdie Druckfeder des Druckfederteiles den in es eingeschobenen Träger ständig kontaktiert und an das Druckfederteil andrückt, ist stets sichere elektrische Verbindung zwischen dem Träger und dem Druckfederteil gewährleistet, so lange diese beiden Teile in Eingriff miteinander sind. Auch in abgehängtem und gegebenenfalls abgeklapptem Zustand des Rasters ist die sichere Schutzleiterverbindung zwischen dem Raster und dem Leuchtengehäuse gewährleistet, solange mindestens ein Träger noch durch die Druckfeder des ihm zugeordneten Druckfederteiles belastet ist. Damit kann es nicht zum vorzeitigen Unterbrechen der elektrisch leitenden Schutzleiterverbindung zwischen dem Raster und dem Träger und dem Leuchtengehäuse kommen, die durch jede einzelne Abhängevorrichtung für sich hergestellt ist.With this luminaire according to the invention, an electrical protective conductor connection between the grid and the luminaire housing, which is secure even under difficult conditions, is obtained via the suspension devices. The suspension devices are structurally simple and are suitable for economical manufacture and quick, easy assembly. They can also be easily designed so that they require little force to insert the carrier into the compression spring parts, even with high locking forces. Since the compression spring of the compression spring part constantly contacts the carrier inserted into it and presses it against the compression spring part, a secure electrical connection between the carrier and the compression spring part is always ensured as long as these two parts are in engagement with one another. Even when the grid is suspended and possibly folded down, the secure protective conductor connection between the Grid and the lamp housing guaranteed as long as at least one carrier is still loaded by the compression spring of the compression spring part assigned to it. This cannot lead to premature interruption of the electrically conductive protective conductor connection between the grid and the support and the luminaire housing, which is made for each individual suspension device.

Auch ist das Aushängen des Trägers aus dem Druckfederteil äußerst einfach vorzunehmen, weil hierzu nur der Träger im Ganzen gegen die Kraft der Druckfeder von Hand so zu bewegen ist, daß sein Haltevorsprung vom Auflager des Druckfederteiles freikommt. Auch das Wiedereinsetzen des Trägers in das Druckfederteil ist äußerst einfach, sei es, daß hierzu der Träger von Hand unter Biegen der Druckfeder außer seiner Aufwärtsbewegung auch seitlich bewegt wird oder daß man den Haltevorsprung obenseitig so schräg ausbildet, daß er bei Aufwärtsbewegung die Druckfeder mit Keilwirkung von selbst biegt.It is also extremely easy to unhook the carrier from the compression spring part, because only the carrier as a whole can be moved by hand against the force of the compression spring so that its retaining projection is released from the support of the compression spring part. Reinstalling the carrier in the compression spring part is extremely simple, be it that for this purpose the carrier is moved laterally by bending the compression spring in addition to its upward movement, or that the retaining projection on the top is so inclined that it compresses the compression spring with a wedge effect when moving upward bends by itself.

Die Bedienung dieser Leuchte ist also selbst für ungeübte Personen äußerst einfach und unproblematisch und es besteht keine Sicherheitsgefahr infolge der ständig guten Schutzleiterverbindung zwischen dem Raster und dem Leuchtengehäuse.The operation of this lamp is extremely easy and unproblematic even for inexperienced people and there is no safety hazard as a result of constantly good protective conductor connection between the grid and the luminaire housing.

Die Leuchte kann von irgendeiner gewünschten Art sein, vorzugsweise eine Deckeneinbauleuchte sein. Das Leuchtengehäuse kann runde, quaderförmige oder sonstige gewünschte Gestalt aufweisen. Bei kleineren Leuchten ist es zumindest in vielen Fällen ausreichend, den Raster nur mittels zwei Abhängevorrichtungen zu halten. Die einzelne Abhängevorrichtung braucht dabei nur aus dem Druckfederteil und dem Träger zu bestehen, wobei diese beiden Teile vorzugsweise kostengünstig herstellbare Stanz- und Biegeteile sein können. Bei größeren Leuchten können jedoch auch mehr als zwei Abhängevorrichtungen vorgesehen sein, vorzugsweise vier.The lamp can be of any desired type, preferably a recessed ceiling lamp. The lamp housing can have a round, cuboid or any other desired shape. In the case of smaller luminaires, it is sufficient, at least in many cases, to hold the grid using only two suspension devices. The individual suspension device need only consist of the compression spring part and the support, these two parts preferably being inexpensive to produce stamped and bent parts. With larger lights, however, more than two suspension devices can be provided, preferably four.

Eine Fehlbedienung ist nicht möglich, da der Träger aus dem Druckfederteil nur unter manuellem Querbewegen ausgehängt werden kann.Incorrect operation is not possible since the support can only be removed from the compression spring part by moving it manually.

Die in der Zeichnung dargestellte Leuchte 10, die vorzugsweise eine Deckeneinbauleuchte sein kann, weist ein metallisches Leuchtengehäuse 11 und einen in ihm mittels Abhängevorrichtungen, wie 9, lösbar gehaltenen metallischen Raster 13 auf. Ferner ist im Leuchtengehäuse 11 eine Lampe 12, die in diesem Ausführungsbeispiel eine gerade Leuchtstofflampe sein kann, angeordnet.The luminaire 10 shown in the drawing, which may preferably be a recessed ceiling luminaire, has a metallic luminaire housing 11 and a metallic grid 13 detachably held in it by means of suspension devices, such as 9. Furthermore, a lamp 12, which in this exemplary embodiment can be a straight fluorescent lamp, is arranged in the lamp housing 11.

Der Raster 13 weist zwei vom Lampenraum aus gesehen konkav gewölbte, als metallische Seitenreflektoren dienende Profilseitenbleche 14 auf, die durch in ihrem unteren Bereich in sie eingesetzte metallische Querlamellen 15 fest und elektrisch leitend miteinander verbunden sind.The grid 13 has two profile side plates 14 which are concavely curved as seen from the lamp space and serve as metallic side reflectors and which are firmly and electrically conductively connected to one another by metallic transverse lamellae 15 inserted in their lower region.

Die Abhängevorrichtungen 9 sind unter sich gleich ausgebildet und weisen je einen Träger 26 und je ein Druckfederteil 33 auf, Jeder Träger 26 ist an ein Halteteil 17 des Rasters 13 schwenkbar angelenkt.The suspension devices 9 are of identical design and each have a support 26 and a compression spring part 33, each support 26 is pivotally articulated to a holding part 17 of the grid 13.

Die Seitenbleche 14 des Rasters 13 weisen untenseitig je eine nach oben offene, sich über ihr Länge erstreckende Rinne 16 auf. In jede solche Rinne ist mindestens ein federndes Halteteil 17 eingesetzt. Je nach Länge der Leuchte 10 können in die einzelnen Rinnen 16 ein Halteteil 17 oder im Abstand voneinander mehrere Halteteile 17 eingesetzt sein, an die je ein Träger 26 schwenkbar angelenkt ist. Eine schaubildliche Ansicht eines solchen Halteteiles 17 ist in Fig. 6 dargestellt. Es besteht aus Federblech und weist untenseitig ebenfalls eine Rinne 19 auf, die formschlüssig in die Rinne 16 des betreffenden Seitenbleches 14 eingesetzt ist.The side plates 14 of the grid 13 each have an upwardly open channel 16 which extends over their length. At least one resilient holding part 17 is inserted into each such groove. Depending on the length of the lamp 10, a holding part 17 or a plurality of holding parts 17 can be inserted into the individual grooves 16, to each of which a support 26 is pivotally articulated. A perspective view of such a holding part 17 is shown in FIG. 6. It consists of spring plate and also has a groove 19 on the underside, which is inserted in a form-fitting manner in the groove 16 of the side plate 14 in question.

Dieses Halteteil 17 weist eine bogenförmige Auswölbung 20 auf, die seiner besseren Eigenfederung dient und obenseitig weist es zwei scharfe Krallen oder Spitzen 21 auf, über die das betreffende Seitenblech 14 hakenförmig umgebogen ist, so daß diese Spitze sich in das Seitenblech 14 sicheren elektrischen Kontakt schaffend etwas eindrücken, da dieses Halteteil 17 federnd vorgespannt ist, so daß dieser sichere elektrische Kontakt ständig aufrecht erhalten wird.This holding part 17 has an arcuate bulge 20, which serves its better self-resilience and on the top it has two sharp claws or tips 21, over which the side plate 14 in question is bent in a hook shape, so that this tip makes safe electrical contact in the side plate 14 push something in, since this holding part 17 is resiliently biased so that this safe electrical contact is constantly maintained.

Das Halteteil 17 ist ein einstückiges Stanz- und Biegeteil, das nach seinem Biegen zur Herstellung seiner federnden Eigenschaften gehärtet wurde. Es weist an der Außenseite seiner Rinne 19 einen Lagerbügel 23 auf, der, wie dargestellt, zwei mit je einem Lagerloch versehene freie Schenkel 22 aufweist. Der diese frei endenden Schenkel 22 verbindende Zwischensteg 25 ist zur besseren Federung dieser die miteinander fluchtenden Lagerlöcher, wie 24, des Bügels 23 aufweisenden Schenkel 22 durch zwei L-förmige, zueinander symmetrische Einschnitte aufgesplissen, so daß diese Schenkel 22 gut federn können. Diese Schenkel 22 des Bügels sind so gebogen, daß sie mit Vorspannung an den in ihren Lagerlöchern 24 drehbar gelagerten starren Träger 26 zur Herstellung sicherer elektrischen Verbindung zwischen dem Halteteil 17 und dem metallischen Träger 26 angedrückt sind. Und zwar ist der Träger 26 ein L-förmig gebogener, starrer Blechstreifen, der an seinem kurzen unteren, ungefähr horizontalen Schenkel 27 zwei mit angestanzte, miteinander fluchtende Zapfen 28 aufweist, die in die Lagerlöcher 24 des Lagerbügels 23 zur Drehlagerung des einen Schwenkbügel bildenden Trägers 26 eingreifen. Wie erwähnt, liegen die beiden Schenkel 22 des Lagerbügels 23 ständig mit Vorspannung an dem in ihnen drehbar gelagerten Träger 26 an, um ständig sicheren elektrischen Kontakt zwischen dem Träger 26 und dem Halteteil 17 zu schaffen.The holding part 17 is a one-piece stamped and bent part which, after it has been bent, has been hardened to produce its resilient properties. It has on the outside of its channel 19 a bearing bracket 23 which, as shown, has two free legs 22 each provided with a bearing hole. The intermediate web 25 connecting these free-ended legs 22 is split for better suspension of these mutually aligned bearing holes, such as 24, of the arm 23 having legs 22 by two L-shaped, symmetrical incisions, so that these legs 22 can spring well. These legs 22 of the bracket are bent so that they are preloaded on the rigid support 26 rotatably mounted in their bearing holes 24 Establishing secure electrical connection between the holding part 17 and the metallic carrier 26 are pressed. Namely, the support 26 is an L-shaped, rigid sheet metal strip, which has on its short lower, approximately horizontal leg 27 two with stamped, aligned pins 28, which in the bearing holes 24 of the bracket 23 for pivoting the bracket forming a pivot bracket 26 intervene. As mentioned, the two legs 22 of the bearing bracket 23 are always with prestress against the support 26 rotatably mounted in them, in order to always provide reliable electrical contact between the support 26 and the holding part 17.

Der in Fig. 5 schaubildlich dargestellte Träger 26 weist an seinem langen, ungefähr vertikalen, geraden Schenkel 29 eine Rastnase 30 und einen Haltevorsprung 31 auf.The carrier 26 shown diagrammatically in FIG. 5 has a latching lug 30 and a retaining projection 31 on its long, approximately vertical, straight leg 29.

Der gesamte Träger 26 ist einstückig aus Blech durch Stanzen und Biegen hergestellt. Sein Haltevorsprung 31 ist als ein durch Stanzen und rechtwinkliges Biegen gebildeter ebener Lappen und die Rastnase 30 ist durch Einstanzen von zwei zueinander parallelen Schlitzen und Ausbiegen des hierdurch gebildeten Steges in ungefähr V-förmige Gestalt hergestellt.The entire support 26 is made in one piece from sheet metal by stamping and bending. Its holding projection 31 is in the form of a flat tab formed by punching and right-angled bending, and the latching lug 30 is made by punching two mutually parallel slots and bending out the resultant thereby Bridges made in approximately V-shaped shape.

Das in Fig. 4 schaubildlich dargestellte Druckfederteil 33 der einzelnen Abhängevorrichtung 9 ist ebenfalls aus Blech durch Stanzen und Biegen hergestellt und besteht aus federndem Metall. Es weist einen ebenen, breiten Hauptbereich 34 auf, der an einem ebenen Bereich der Seitenwand 35 des Leuchtengehäuses 11 anliegt. Obenseitig schließen an diesen Hauptbereich 34 zwei im Bogen nach oben führende Krallen oder Zinken 36 an, die durch kleine Löcher der Decke 37 des Leuchtengehäuses 11 hindurchragen und die sich von ihren freien Enden aus in abwärtiger Richtung so verbreitern, daß sie an die Ränder dieser Löcher mit federnder Eigenvorspannung ständig angedrückt sind, um ständige, sichere elektrische Verbindung zwischen dem metallischen Leuchtengehäuse 11 und diesem metallischen Druckfederteil 33 zu schaffen.The compression spring part 33 of the individual suspension device 9, shown diagrammatically in FIG. 4, is also made of sheet metal by punching and bending and is made of resilient metal. It has a flat, broad main area 34, which bears on a flat area of the side wall 35 of the lamp housing 11. On the upper side adjoin this main area 34 two claws or tines 36 leading upwards in an arc, which protrude through small holes in the ceiling 37 of the lamp housing 11 and which widen in a downward direction from their free ends so that they reach the edges of these holes are constantly pressed with resilient self-bias to create permanent, secure electrical connection between the metallic lamp housing 11 and this metallic compression spring part 33.

Dieses einstückige Druckfederteil 33 weist ferner in der Nähe seines unteres Endes, kurz oberhalb seines abgekröpften Endbereiches 38 zwei schräg nach hinten unten ragende, federnde Lappen auf, die durch entsprechende kleine Löcher in der Seitenwand 35 des Gehäuses 11 auf deren unteren Rändern fest aufsitzend hindurchragen. Dieses Druckfederteil 33 ist hierdurch untenseitig am Leuchtengehäuse abgestützt und seine Zinken 36 sind ständig mit federnder Vorspannung an die Ränder der von ihnen durchdrungenen Deckenlöcher des Leuchtengehäuses 11 angedrückt, so daß es am Leuchtengehäuse lösbar gehalten ist.This one-piece compression spring part 33 also has in the vicinity of its lower end, just above its cranked end region 38, two resilient tabs projecting obliquely backwards downwards, which are seated firmly on the lower edges of the housing 11 through corresponding small holes in the side wall 35 protrude through. This compression spring part 33 is thereby supported on the underside of the lamp housing and its prongs 36 are constantly pressed with resilient bias against the edges of the ceiling holes of the lamp housing 11 which they penetrate, so that it is detachably held on the lamp housing.

Dieses Druckfederteil 33 weist eine zungenförmige Blattfeder 39 auf, die einstückig an es mit angestanzt ist und deren freier Endbereich, wie dargestellt, V-formig abgewinkelt ist. Diese Blattfeder 39 setzt am oberen Rand eines umfangsseitig geschlossenen Durchbruches 40 des Druckfederteiles einstückig an, welcher Durchbruch 40 sich von dem oberen Fuß der Blattfeder 39 aus ungefähr bis zum Beginn des untersten, ebenen Endbereiches 41 des Druckfederteiles 33 oder noch in ihn ein kurzes Stück hinein erstreckt. Dieser konstante Breite aufweisende Durchbruch 40 geht hier also auch durch den senkrecht zu dem unteren Endbereich 41 und zu dem Hauptbereich 34 verlaufenden kurzen, ebenen Querbereich 42 des Druckfederteiles 33 hindurch. Der Querbereich 42 ist horizontal und die Bereiche 34, 41 sind vertikal gerichtet.This compression spring part 33 has a tongue-shaped leaf spring 39 which is stamped in one piece with it and whose free end region, as shown, is angled in a V-shape. This leaf spring 39 attaches in one piece to the upper edge of a circumferentially closed opening 40 of the compression spring part, which opening 40 extends from the upper foot of the leaf spring 39 approximately to the beginning of the lowest, flat end region 41 of the compression spring part 33 or a short distance into it extends. This opening 40, which has a constant width, therefore also passes through the short, flat transverse region 42 of the compression spring part 33 which runs perpendicular to the lower end region 41 and to the main region 34. The transverse region 42 is horizontal and the regions 34, 41 are directed vertically.

Dieser Durchbruch 40 ist vom Träger 26, wie dargestellt, durchdrungen und der Träger 26 kann aus ihm nur in abwärtiger Richtung unter gleichzeitigem manuellen Seitwärtsbewegen herausgezogen werden, so daß der Träger 26 gegen unbeabsichtigtes Abnehmen vom Druckfederteil 33 gesichert ist.This opening 40 is penetrated by the carrier 26, as shown, and the carrier 26 can only from it in the downward direction at the same time manual sideways movement are pulled out so that the carrier 26 is secured against unintentional removal from the compression spring part 33.

Der untere Rand 43 des Durchbruches 40 bildet sowohl ein Auflager für den Haltevorsprung 31 des Trägers 26 als auch eine Raste für die Rastnase 30 des Trägers 26.The lower edge 43 of the opening 40 forms both a support for the holding projection 31 of the carrier 26 and a catch for the locking lug 30 of the carrier 26.

In der in das Leuchtengehäuse 11 eingesetzten Betriebstellung des Rasters 13 befindet sich der den Durchbruch 40 des Druckfederteiles, wie dargestellt, durchdringende Träger 26 in seiner obersten, mit dem Druckfederteil 33 verrasteten Stellung, in welcher seine Rastnase 30 mit ihrem unteren Ende durch die Druckfeder 39 des Druckfederteiles 33 seitlich an den hierbei als Raste dienenden unteren Rand 43 des Durchbruches 40 angedrückt ist.In the operating position of the raster 13 inserted into the luminaire housing 11, the support 26 penetrating the opening 40 of the compression spring part, as shown, is in its uppermost position, which is latched to the compression spring part 33 and in which its lower end 30 is held by the compression spring 39 of the compression spring part 33 is pressed laterally onto the lower edge 43 of the opening 40, which serves as a catch.

Wenn man den Raster 13 aus dieser Betriebstellung von Hand nach unten zieht unter Überwindung der von den Druckfedern 39 erzeugten Rastkräfte dieser Verrastungen der Träger 26 mit den Druckfederteilen 33 der Abhängevorrichtungen 9, gleiten dabei zunächst die Rastnasen 30 mit ihren kurzen unteren schrägen Bereichen auf den unteren Rändern 43 der Durchbrüche 40 der Druckfederteile 33 und hierdurch werden die Träger 26 durch ihre Rastnasen 30 verschwenkt und die Blattfedern 39 der Druckfederteile 33 durch die Träger 26 entsprechend unter Anstieg ihrer Federkräfte gebogen. Sobald die Scheitel der Rastnasen 30 an den Rändern 43 nach unten vorbeigelangt sind, sind hierdurch die Träger 26 aus den Druckfederteilen 33 ausgerastet und man kann den Raster 13 weiter nach unten bewegen, und zwar in vertikaler gerader Richtung so lange, bis die Haltevorsprünge 31 diese Abwärtsbewegung abstoppen.Bei dieser Abwärtsbewegung des Rasters 13 bleiben die Träger 26 ständig durch die Druckfedern 39 an die Ränder 43 angedrückt, so daß hierdurch sicherer elektrischer Schutzkontakt auch während dieses Abwärtsbewegens des Rasters 13 gewährleistet ist. Diese Abwärtsbewegung des Rasters 13 endet, wenn die Haltevorsprünge 31 auf die dabei für sie Auf-oder Widerlager bildenden Ränder 43 zur Auflage kommen, wie es Fig. 7 an einem Beispiel zeigt. Diese Haltevorsprünge 31 sind rechtwinklig zur Längsrichtung der ungefähr vertikalen, langen Schenkel 29 der Träger 26 gerichtet und können folglich nicht an den Rändern 43 von selbst vorbeigelangen, sondern kommen auf ihnen zur sicheren Auflage, so daß nunmehr die abgehängte Stellung des Rasters nach Fig. 3 eingestellt ist, in der der Raster 13 in abgehängter horizontaler Lage durch die Abhängevorrichtungen 9 gehalten ist.If you pull the grid 13 from this operating position by hand, overcoming the locking forces generated by the compression springs 39, these lockings of the supports 26 with the compression spring parts 33 of the suspension devices 9, the locking lugs 30 with their short, lower, sloping regions initially slide onto the lower ones Edges 43 of Openings 40 of the compression spring parts 33 and thereby the supports 26 are pivoted by their locking lugs 30 and the leaf springs 39 of the compression spring parts 33 are bent accordingly by the supports 26 with an increase in their spring forces. As soon as the vertices of the latching lugs 30 have passed the edges 43 downward, the supports 26 are thereby disengaged from the compression spring parts 33 and the grid 13 can be moved further downward, in a vertical straight direction until the retaining projections 31 are this Stop this downward movement. With this downward movement of the grid 13, the supports 26 remain constantly pressed against the edges 43 by the compression springs 39, so that thereby secure electrical protective contact is ensured even during this downward movement of the grid 13. This downward movement of the grid 13 ends when the holding projections 31 come to rest on the edges 43 which form supports or abutments for them, as shown in FIG. 7 using an example. These holding projections 31 are directed at right angles to the longitudinal direction of the approximately vertical, long legs 29 of the supports 26 and consequently cannot pass the edges 43 by themselves, but come to rest securely on them, so that now the suspended position of the grid according to FIG. 3 is set in which the Grid 13 is held in a suspended horizontal position by the suspension devices 9.

Wenn man den Raster 13 nunmehr abklappen will, dann verschwenkt man von Hand den oder die betreffenden Träger 26 an der gewünschten Seite des Leuchtengehäuses, wo man ihn oder sie zu diesem Zweck aus dem oder den zugeordneten Druckfederteilen 33 aushängen will, gegen die Kraft der betreffenden Druckfeder 39 oder Druckfedern, bis der oder die Haltevorsprünge 31 aus der oder den Durchbrüchen 40 des oder der betreffenden Druckfederteile freikommt bzw. -kommen. Man kann dann den oder die betreffenden Träger 26 vollends nach unten aus diesem oder diesen Druckfederteilen 33 herausziehen und der Raster 13 gelangt dann in eine noch einseitig aufgehängte , abgeklappte Schwenkstellung, wie sie an einem Beispiel in Fig. 3 strichpunktiert dargestellt ist. Wenn man den Raster 13 vollends abnehmen will, kann man dann auch den oder die restlichen Träger 26 aus dem oder den zugeordneten Druckfederteilen 33 aushängen. Wenn man den Raster nicht in die in Fig. 3 dargestellte Schwenkstellung abklappen will, sondern in die entgegengesetzte Schwenkstellung, dann ist dies ohne weiteres möglich, indem man den oder die rechtsseitig befindlichen Träger 26 nicht aushängt, sondern den oder die linksseitig befindlichen Träger 26.If you now want to fold the grid 13, then you pivot the hand or the relevant support 26 on the desired side of the lamp housing, where you want to unhook him or her for this purpose from the associated compression spring parts 33 against the force of the concerned Compression spring 39 or compression springs until the retaining protrusion (s) 31 comes out of the opening (s) 40 of the compression spring component (s) in question. The carrier or carriers 26 in question can then be pulled completely downwards out of this or these compression spring parts 33 and the grid 13 then moves into a pivoted position which is still suspended on one side and is folded down, as is shown by dash-dotted lines in an example in FIG. 3. If you want to remove the grid 13 completely, you can then unhook the rest of the support 26 or 26 from the associated compression spring parts 33. If one does not want to fold down the grid into the swivel position shown in FIG. 3, but rather into the opposite swivel position, then this is easily possible by not unhooking the support or supports 26 located on the right, but rather the one or the carriers 26 located on the left.

Die Druckfedern 39 gewährleisten sicheren elektrischen Kontakt der Träger 26 mit ihnen, solange die Träger 26 nicht aus den Druckfederteilen 33 ausgehängt sind. Auch alle anderen Verbindungsstellen zwischen Leuchtengehäuse 11 und Raster 13 über die Abhängevorrichtungen 9 sind elektrisch leitende Verbindungen, so daß hervorragende und sichere elektrische Schutzleiterverbindung zwischen dem Raster 13 und dem Leuchtengehäuse 11 über jede einzelne der Abhängevorrichtungen 9 sichergestellt ist, solange noch mindestens ein Träger 26 in das zugeordnete Druckfederteil 33 eingesetzt ist. Auch sind diese Abhängevorrichtungen 9 konstengünstig und sehr einfach zu montieren und ermöglichen äußerst einfaches Abhängen und Abklappen des Rasters 13 auch durch ungeübte Personen. Auch das Zurückführen des Rasters 13 in seine in das Leuchtengehäuse 11 eingesetzte Betriebsstellung ist ebenfalls denkbar einfach und kann ebenfalls auch von ungeübten Personen, wie Hausfrauen oder dergl. ohne weiteres vorgenommen werden. Denn es ist nur notwendig, den oder die ausgehängten Träger 26 wieder in das oder die Druckfederteile 33 von unten her einzuschieben, wobei man ihn oder sie lediglich so drückt, daß sein oder ihre Haltevorsprünge 31 durch die Durchbrüche 40 der Druckfederteile 33 hindurch wieder über den oder die unteren Ränder 43 der Durchbrüche 40 hinaus gelangen.The compression springs 39 ensure reliable electrical contact of the supports 26 with them as long as the supports 26 are not detached from the compression spring parts 33. All other connection points between the lamp housing 11 and grid 13 via the suspension devices 9 are electrically conductive connections, so that excellent and secure electrical protective conductor connection between the grid 13 and the lamp housing 11 is ensured via each of the suspension devices 9, as long as at least one carrier 26 in the associated compression spring part 33 is inserted. These suspension devices 9 are also inexpensive and very easy to assemble and enable extremely simple suspension and folding of the grid 13 even by inexperienced people. The return of the grid 13 into its operating position inserted into the lamp housing 11 is also extremely simple and can also be carried out by inexperienced persons such as housewives or the like. Because it is only necessary to push the unhooked carrier 26 back into the compression spring parts 33 from below, one just pressing him or her so that his or her retaining projections 31 through the openings 40 of the compression spring parts 33 through again over the or the lower edges 43 of the openings 40 get out.
