Description

Die Erfindung betrifft eine Leuchte mit mindestens einer langgestreckten in einem Leuchtengehäuse angeordneten Lampe, einer die Lampe übergreifenden und das Leuchtengehäuse verschließenden, durchsichtigen oder durchscheinenden Leuchtenwanne mit umlaufendem Rand, insbesondere Krallrand, die über mehrere Verschlüsse mit dem Leuchtengehäuse lösbar verbunden ist.The invention relates to a luminaire with at least one elongated lamp arranged in a luminaire housing, a lamp luminaire spanning the lamp and closing, transparent or translucent luminaire trough with a peripheral edge, in particular claw rim, which is detachably connected to the luminaire housing via a plurality of closures.

Eine auf dem Markt bekannte Leuchte weist einen, sich über die gesamte Länge der Seitenkante erstreckenden, Hinterschnitt des Leuchtengehäuses auf, der den Rand der Leuchtenwanne, der als Krallrand, d.h. nach außen gebogenem Rand ausgeführt ist, ebenfalls über die gesamte Länge übergreift.A lamp known on the market has an undercut of the lamp housing, which extends over the entire length of the side edge, which undercuts the edge of the lamp trough, which acts as a claw edge, i.e. outwardly bent edge is also overlaps over the entire length.

Als Nachteil dieser Leuchte wird hierbei angesehen, daß die Leuchte nur mit Mühe wieder geöffnet werden kann, insbesondere wenn diese eine bestimmte Lange überschreitet.A disadvantage of this lamp is considered that the lamp can be opened again only with difficulty, especially if it exceeds a certain length.

Ferner sind Leuchten bekannt, bei denen am Leuchtengehäuse mehrere Schnappverschlüssse gelenkig angebracht sind, die am Rand der Wanne, die hierfür einen Krallrand aufweisen muß, eingehängt werden können und dann in eine Schließstellung umgeklappt werden können. Zwar kann eine Leuchte mit derartigen Verschlüssen leichter geöffnet werden, jedoch sind diese Verschlüsse einerseits aufwendig herzustellen, andererseits muß das Leuchtengehäuse mit speziell für diese Verschlüsse ausgebildeten Aufnahmen versehen werden, in die die Verschlüsse eingehängt oder eingeklipst werden.Furthermore, lights are known in which several snap locks are articulated on the light housing, which can be hung on the edge of the tub, which must have a claw edge for this purpose, and can then be folded down into a closed position. Although a lamp with such closures can be opened more easily, these closures are complicated to manufacture on the one hand, on the other hand, the lamp housing must be provided with receptacles specially designed for these closures, into which the closures are hung or clipped.

Schließlich sind ist noch weitere Leuchte bekannt, wie sie beispielsweise in der DE 80 24 546 U1 oder der DE 84 31 426 U1 beschrieben sind, bei denen ohne zusätzliche Bauteile die Leuchtenwanne am Leuchtengehäuse angeklipst werden können.Finally, further luminaires are known, such as those described in DE 80 24 546 U1 or DE 84 31 426 U1, in which the luminaire trough can be clipped onto the luminaire housing without additional components.

Hierfür weist der im wesentlichen senkrechte Rand des Leuchtengehäuses den einen Teil des Verschlusses, meist in Form eines angespritzten Hakens, und der Rand der Leuchtenwanne den anderen Teil des Verschlusses auf, so daß durch Aufstecken der Leuchtenwanne auf das Leuchtengehäuse die beiden Teile der Verschlüsse ineinandergefügt und miteinander verrastet werden können. Als nachteilig wird bei dieser Art Leuchte angesehen, daß die Leuchtenwanne, die in der Regel aus einen sehr spröden Werkstoff, beispielsweise Polymethylmetacrylat, besteht, mit dem Verschlußteil versehen werden muß und daher beispielsweise nicht mehr durch einfaches Warmformen herzustellen ist. Beim Anbringen der Leuchtenwanne am Leuchtengehäuse bzw. beim Lösen werden die Verschlußteile Biegebelastungen ausgesetzt, sodaß die Gefahr besteht, daß das aus einem spröden Werkstoffbestehende Verschlußteil der Leuchtenwanne beschädigt wird. Ist eines dieses Verschlußteil beschädigt, kann die Leuchtenwanne nur noch ungenügend am Leuchtengehäuse befestigt werden, insbesondere ist dann die bei einer voll funktionsfähigen Leuchte ggf. vorhandene Staub und Spritzwasserdichtigkeit nicht mehr gegeben.For this purpose, the substantially vertical edge of the lamp housing has one part of the closure, usually in the form of a molded hook, and the edge of the lamp trough has the other part of the closure, so that the two parts of the closures are inserted into one another by plugging the lamp trough onto the lamp housing can be locked together. A disadvantage of this type of luminaire is that the luminaire trough, which generally consists of a very brittle material, for example polymethyl methacrylate, must be provided with the closure part and can therefore no longer be produced, for example, by simple thermoforming. When attaching the luminaire trough to the luminaire housing or when loosening, the closure parts are subjected to bending loads, so that there is a risk that the closure part of the luminaire trough consisting of a brittle material will be damaged. If one of these locking parts is damaged, the luminaire tray can only be insufficiently attached to the luminaire housing; in particular, the dust and splash water tightness that may be present in a fully functional luminaire is then no longer ensured.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Leuchte mit Verschlüssen zu versehen, wobei hierfür kein zusätzliches Bauteil benötigt wird, diese möglichst einfach zu bedienen sind und die Gefahr einer Beschädigung der Leuchtenwanne durch mechanischen Beanspruchungen der Verschlüsse klein ist.The invention is therefore based on the object of providing a lamp with closures, no additional component being required for this, these being as simple as possible to use and the risk of damage to the lamp tub being small due to mechanical stresses on the closures being small.

Diese Aufgabe löst die Erfindung dadurch, daß das Leuchtengehäuse einen umlaufenden Stehrand und eine gegenüber diesem tieferliegende Nut aufweist und daß die Verschlüsse einstückig an den umlaufenden Stehrand angeformt sind und in die den Rand der Leuchtenwanne aufnehmende Nut derart hineinragen, daß sie bei eingesetzter Leuchtenwanne deren nach außen gebogenen Rand übergreifen.This problem is solved by the invention in that the lamp housing has a circumferential standing edge and a groove lying opposite it, and in that the closures are integrally formed on the circumferential standing edge and protrude into the groove receiving the edge of the lamp trough in such a way that when the lamp trough is inserted, they follow it overlap the outside curved edge.

Diese Lösung hat den Vorteil, daß die Verschlüsse an das Leuchtengehäuse integriert sind, sodaß keine zusätzlichen Bauteile benötigt werden und die Verschlüsse zusammen mit dem Leuchtengehäuse als Spritzgußteil herstellbar sind. Außerdem sind die Verschlüsse lediglich am Leuchtengehäuse vorgesehen, sodaß die Leuchtenwanne keine besonderen Bauteile aufweist, die beim Schließen und Öffnen der Leuchte übermäßig beansprucht werden könnten. Im Gegensatz zur Leuchtenwanne, die meist aus einem spröden Material besteht, besteht das Wannengehäuse aus einem zähen Material, beispielsweise Polycarbonat. Daher können die Verschlüsse ohne die Gefahr einer Beschädigung bis zu einem gewissen Grad verformt werden.This solution has the advantage that the closures are integrated into the lamp housing, so that no additional components are required and the closures can be produced together with the lamp housing as an injection molded part. In addition, the closures are only provided on the lamp housing, so that the lamp tray has no special components that could be excessively stressed when closing and opening the lamp. In contrast to the lamp tray, which usually consists of one brittle material, the tub housing is made of a tough material, such as polycarbonate. Therefore, the closures can be deformed to a certain extent without the risk of damage.

Zur Vereinfachung der Demontage kann am Verschluß eine Griffnase vorgesehen sein, die über den Stehrand übersteht. Durch diese wird für den Monteuer sowohl die Verschlußstelle gekennzeichnet, als auch eine einfachere Bedienung ermöglicht.To simplify disassembly, a handle can be provided on the closure, which protrudes beyond the standing edge. This means that both the locking point is marked for the installer and it is easier to operate.

Vorzugsweise werden die Verschlüsse gleichmäßig über den Umfang oder über die Seitenlängen des Leuchtengehäuses verteilt vorgesehen. Durch diese gleichmäßige Verteilung der Verschlüsse wird auch die mechanische Belastung der Leuchtenwanne auf deren gesamten Umfang gleichmäßig verteilt und der Rand der Leuchtenwanne gleichmäßig in der umlaufenden Nut des Leuchtengehäuses gehalten.The closures are preferably provided evenly distributed over the circumference or over the side lengths of the lamp housing. As a result of this even distribution of the closures, the mechanical load on the luminaire trough is evenly distributed over its entire circumference and the edge of the luminaire trough is held evenly in the circumferential groove of the luminaire housing.

In einer bevorzugten Weiterbildung der Erfindung wird in die Nut des Leuchtengehäuses ein Dichtungsband eingelegt. Bei geschlossener Leuchte wird der Rand der Leuchtenwanne durch die übergreifenden Verschlüsse gegen das Dichtungsband gedrückt. Durch diese Abdichtung kann die Leuchte auch als Feuchtraumleuchte verwendet werden.In a preferred development of the invention, a sealing tape is inserted into the groove of the lamp housing. When the lamp is closed, the edge of the lamp trough is pressed against the sealing tape by the overlapping closures. Thanks to this seal, the luminaire can also be used as a damp room luminaire.

In einer Weiterbildung der Erfindung werden mindestens zwei weitere Aufnahmeeinrichtungen auf der gleichen Seitenlänge des Leuchtengehäuses an den Verschlüssen oder an den Stehrand einstückig angeformt, in die der Rand der Leuchtenwanne im geöffneten Zustand der Leuchte eingehängt werden kann. Diese Aufnahmeeinrichtungen können sowohl an einen Verschluß integriert sein, als auch an anderer Stelle an den Stehrand angeformt sein, falls dies aus stabilitätsgründen wünschenswert bzw. erforderlich ist.In a further development of the invention, at least two further receiving devices are integrally formed on the closures or on the standing edge on the same side length of the lamp housing, into which the edge of the lamp trough can be hung when the lamp is open. These receptacles can be integrated on a closure as well as molded onto the standing edge at another point, if this is desirable or necessary for reasons of stability.

Mit diesen weiteren Aufnahmeeinrichtung für den geöffneten Zustand der Leuchte wird, insbesondere bei Deckenmontage, die Montage und Wartung der Leuchte erleichtert.With this additional receiving device for the open state of the lamp, the assembly and maintenance of the lamp is facilitated, in particular for ceiling mounting.

Die Leuchte 10 besteht aus einem Leuchtengehäuse 12, einer das Leuchtengehäuse verschließenden, durchsichtigen oder durchscheinenden Leuchtenwanne 14 mit einem umlaufenden Rand 16. Das Leuchtengehäuse 12 weist einen umlaufenden Stehrand 18,18' und eine gegenüber diesem tieferliegende Nut 20 auf, in die ein Dichtungsband 22 eingelegt ist.The luminaire 10 consists of a luminaire housing 12, a transparent or translucent luminaire trough 14 which closes the luminaire housing and has a circumferential edge 16. The luminaire housing 12 has a circumferential standing edge 18, 18 'and a groove 20 lying deeper in relation to this, into which a sealing strip 22 is inserted.

An den Stehrand 18, 18' sind einstückig Verschlüsse 24, 24' angeformt, die aus Ausformungen 26, 26' des Stehrandes 18, 18', an diesen angeformten Rasthaken 28, 28' und Griffnasen 30, 30' gebildet werden. Von diesen Verschlüssen 24, 24' sind mehrere gleichmäßig verteilt auf den beiden gegenüberliegenden Seitenlängen des Leuchtengehäuses angebracht.Closures 24, 24 'are integrally formed on the standing edge 18, 18', which are formed from formations 26, 26 'of the standing edge 18, 18', locking hooks 28, 28 'formed thereon and grip tabs 30, 30'. Several of these closures 24, 24 'are evenly distributed on the two opposite side lengths of the lamp housing.

In dem in Fig.1 dargestellten Zustand der Leuchte 10 ragen die Rasthaken 28, 28' soweit in die Nut 20 des Leuchtengehäuses 12, daß sie das äußerste Ende des Rands 16 der Leuchtenwanne 14 übergreifen und den Bogen des Randes gegen das Dichtüngsband 22 drücken und somit die Leuchte staub-und spitzwasserdicht, bis zu wasserdicht verschlossen ist.In the state of the lamp 10 shown in FIG. 1, the latching hooks 28, 28 'project so far into the groove 20 of the lamp housing 12 that they overlap the extreme end of the edge 16 of the lamp trough 14 and press the arch of the edge against the sealing strip 22 and thus the light is dustproof and splashproof up to the watertight closure.

Zur leichteren Führung der Leuchtenwanne beim später beschriebenen Schließen der Leuchte sind auf der Innenseite des Leuchtengehäuses entlang der Nut 20, verteilt über den Umfang Zentrierstege 32, 32' vorgesehen.For easier guidance of the lamp tray when closing the Luminaires are provided on the inside of the luminaire housing along the groove 20, distributed over the circumference of centering webs 32, 32 '.

Zum Öffnen der Leuchte wird, wie in Fig. 1b dargestellt, die Ausformung 26 der auf einer Seiterlänge liegenden Verschlüsse 24 in Pfeilrichtung aufgebogen, bis der Rand 16 vollständig freigegeben ist. Das Dichtungsband drückt den Rand der Leuchtenwanne aus der Nut 20, sodaß die Rastnase 28 den Rand 16 nicht wieder übergreifen kann. Damit können nacheinander die auf der gleichen Längsseite liegende, im Schnitt nicht dargestellten, Verschlüsse 24 mühelos geöffnet werden. Für das Leuchtengehäuse und den Verschluß wird beispielsweise ein zähes Kunststoffmaterial (Polycarbonat) verwendet, bei dem die dargestellte, erforderliche Verformung der Ausformung 26 ohne Beschädigung möglich istTo open the lamp, as shown in FIG. 1b, the shape 26 of the closures 24 lying on one side length is bent in the direction of the arrow until the edge 16 is completely released. The sealing strip presses the edge of the lamp tray out of the groove 20, so that the locking lug 28 cannot overlap the edge 16 again. The closures 24 lying on the same long side, not shown in section, can thus be opened effortlessly one after the other. For the luminaire housing and the closure, for example, a tough plastic material (polycarbonate) is used, in which the required deformation of the formation 26 shown is possible without damage

Nachdem alle Verschlüsse 24 auf einer Seitenlänge der Leuchte 10 geöffnet sind, wird die Leuchtenwanne 14 in einer Drehbewegung (Fig. 1c) mit einem Drehpunkt in den Verschlüssen 24' der gegenüberliegenden Seiterlänge der Leuchte soweit gedreht, bis schließlich wie in Fig. 1d dargestellt die Leuchtenwanne 14 aus den Verschlüssen 24' entnommen werden kann.After all the closures 24 on one side length of the lamp 10 are opened, the lamp trough 14 is rotated in a rotational movement (FIG. 1c) with a pivot point in the closures 24 'of the opposite side length of the lamp until finally shown in FIG. 1d Luminaire tray 14 can be removed from the closures 24 '.

Zum Verschließen der Leuchte 10 kann im Prinzip in umgekehrter Folge vorgegangen. Wobei zunächst auf einer Seitenlänge des Leuchtengehäuses 12 die Leuchtenwanne 14 in die Verschlüsse 24' eingesetzt wird, dann durch eine Drehbewegung in diesen Verschlüssen 24' die Leuchtenwanne zu den Verschlüssen 24 auf der gegenüberliegenden Seite geführt. Beim Schließen muß die Ausformung 26 nicht wie in Fig. 1b dargestellt aufgebogen werden, sondern der Rand 16 wird gegen die schräge Ebene 34 des Rasthakens 28 gedrückt und biegt dabei die Ausformung 26 soweit auf, daß der Rand 16 in die Nut 20 eingeführt werden kann.In principle, the reverse procedure can be used to close the lamp 10. First, the lamp trough 14 is inserted into the closures 24 'on one side length of the lamp housing 12, then the lamp trough is guided to the closures 24 on the opposite side by a rotary movement in these closures 24'. When closing the formation 26 does not have to be bent as shown in Fig. 1b, but the edge 16 is pressed against the inclined plane 34 of the locking hook 28 and bends the formation 26 so far that the edge 16 can be inserted into the groove 20 .

Der Aufbau der Verschlüsse 24, 24' erlaubt aber auch eine gleichzeitige, senkrechte Einführung der Leuchtenwanne, bei der sowohl die Verschlüsse 24 als auch die gegenüberliegenden Verschlüsse 24' über die schräge Ebene 34, 34' der Rasthaken 28, 28' aufgedrückt werden und der Rand 16 in die Nut 20 eingeführt werden kann.The structure of the closures 24, 24 'also allows simultaneous, vertical insertion of the lamp tray, in which both the closures 24 and the opposing closures 24' are pressed over the inclined plane 34, 34 'of the latching hooks 28, 28' and Edge 16 can be inserted into the groove 20.

Fig.2 zeigt durch Verdeutlichung eine ausgebrochene Seitenansicht eines Verschlusses 24.2 shows a broken side view of a closure 24 by way of illustration.

An den Stehrand 18 ist einstückig die Ausformungen 26, 26' angeformt. Die Griffnase 30 ragt trapezförmig über den Stehrand 18 hinaus und kennzeichnet damit für den Benutzer zusätzlich den Verschluß und damit die Stelle an der ein Rasthaken 28 (Fig.1) in die Nut 20 (Fig.1) ragt.The molded portions 26, 26 'are integrally formed on the standing edge 18. The grip nose 30 protrudes in a trapezoidal shape beyond the standing edge 18 and thus additionally identifies the closure for the user and thus the point at which a latching hook 28 (FIG. 1) projects into the groove 20 (FIG. 1).

Fig. 3 zeigt eine ausgebrochene Draufsicht auf einen Verschlußbereich in der die langgestreckte Form der Zentrierstege 32 erkennbar ist. Die Ausformung 26 ragt auch seitlich etwas über den Stehrand 18 hinaus um hier mit nahezu gleicher Materialstärke zusätzlich Raum für die Rastnase 28 zu schaffen. Im Verschlußbereich vejüngt sich auch die Nut 20, wodurch einerseits eine zusätzliche Klemmwirkung für das Dichtband 22 erzielt wird und andererseits Platz für eine Öffnung 36 geschaffen wird, in der bei der Herstellung des Leuchtengehäuses 12 ein Tauchkern liegt. Dadurch wird die Ausformung des Verschlusses 24 und dessen Rastnase 28 mit einfachen Werkzeugen ermöglicht und komplizierte Schieber u.a. vermieden.Fig. 3 shows a broken plan view of a closure area in which the elongated shape of the centering webs 32 can be seen. The shape 26 also protrudes laterally beyond the standing edge 18 in order to create additional space for the locking lug 28 here with almost the same material thickness. In the closure area, the groove 20 also tapers, which on the one hand achieves an additional clamping effect for the sealing tape 22 and on the other hand creates space for an opening 36 in which a plunger core lies during the manufacture of the luminaire housing 12. This enables the closure 24 and its locking lug 28 to be shaped with simple tools and complicated slides, among other things. avoided.

In den Fig. 4a und b ist zusätzlich an den Verschlüssen 24', weitere Aufnahmeeinrichtung 40 angeformt, die im Wesentlichen aus einer L-förmigen, zur Mitte des Leuchtengehäuses gerichteten, Haken 41 besteht, wobei zwischen dem Schenkel 42 des Hakens und der Ausformung 26' des Verschlusses 24' ein Schlitz gebildet wird, in den der Rand 16 der Leuchtenwanne 14 eingeführt werden kann.4a and b, additional receptacle 40 is integrally formed on the closures 24 ', which essentially consists of an L-shaped hook 41 directed towards the center of the lamp housing, between the leg 42 of the hook and the shape 26 'of the closure 24' a slot is formed, into which the edge 16 of the lamp tray 14 can be inserted.

Die Aufnahmeeeinrichtungen 40 können auch an Bereiche des Stehrandes 18 angeformt sein, an denen keine Verschlüsse liegen, da wie aus Fig. 3 erkennbar ist, der Stehrand an den Verschlußstellen nur unwesentlich dicker ist und daher die Lage der Aufnahmeeinrichtung nicht von der Lage des Verschlusses abhängig ist.The receiving devices 40 can also be molded onto areas of the standing edge 18 where there are no closures, since, as can be seen from FIG. 3, the standing edge at the closing points is only insignificantly thicker and therefore the position of the receiving device does not depend on the position of the closure is.

Diese Aufnahmeeinrichtung 40 wird verwendet um bei Montage oder Wartungsarbeiten an der Leuchte 10 beispielsweise bei Deckenmontage die Leuchtenwanne 14 im geöffneten Zustand der Leuchte 10 einzuhängen.This receiving device 40 is used to mount the lamp trough 14 in the open state of the lamp 10 during assembly or maintenance work on the lamp 10, for example when mounting on the ceiling.

Dazu wird wie in Fig. 4a dargestellt, der Rand 16 der Leuchtenwanne 14 in den zwischen L-förmiger Haken 41 und Ausformung 26' verbleibenden Schlitz eingeführt, und danach nach unten gedreht. Der Rand 16 greift dabei hinter den Schenkel 42 der Aufnahmeeinrichtung 40, wobei abhängig vom Gewicht der Leuchtenwanne 14 und der Biegesteifigkeit der Aufnahmeeinrichtung diese auch noch zusätzlich leicht aufgebogen werden kann.For this purpose, as shown in FIG. 4a, the edge 16 of the lamp trough 14 is inserted into the slot remaining between the L-shaped hook 41 and the formation 26 ', and then turned downwards. The edge 16 engages behind the leg 42 of the receiving device 40, and depending on the weight of the lamp trough 14 and the bending stiffness of the receiving device, the latter can also be slightly bent open.

Die Fig. 5 und 6 zeigen zur Verdeutlichung eine ausgebrochene Seitenansicht eines Verschlusses mit angeformter Aufnahmeeinrichtung bzw. eine ausgebrochene Draufsicht.5 and 6 show a broken side view of a closure for clarification with molded receiving device or a broken top view.

In der Fig. 6 ist erkennbar, daß der Haken 41 über schräge Stege 44, 44', die von der Ausformung 26 ausgehen, an der Außenseite des Leuchtengehäuses 12 angeformt wird und durch den Schenkel 42 ein Schlitz zur Ausformung 26 gebildet wird.In Fig. 6 it can be seen that the hook 41 is formed on the outside of the lamp housing 12 via oblique webs 44, 44 ', which emanate from the formation 26 and a slot for the formation 26 is formed by the leg 42.

Auch hier wird durch diese Art der Ausformung eine Öffnung 46 geschaffen in der bei der Herstellung des Leuchtengehäuses 12 ein Tauchkern liegt. Dadurch wird die Ausformung des Aufnahmeeinrichtung 40 und deren zur Innenseite hin stehendem Schenkel 42 mit einfachen Werkzeugen ermöglicht und komplizierte Schieber u.a. vermieden.Here, too, this type of shaping creates an opening 46 in which a plunger core lies when the lamp housing 12 is manufactured. This makes it possible to shape the receiving device 40 and its leg 42, which faces towards the inside, with simple tools and complicated slides, among other things. avoided.
