Description

Die vorliegende Erfindung betrifft eine Haltevorrichtung für die Lampenfassungen einer sog. zweiflammige Leuchte gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a holding device for the lamp holders of a so-called two-lamp lamp according to the preamble of claim 1.

Leuchten mit länglichen Gasentladungslampen sind in den unterschiedlichsten Formen bekannt. Die Halterung und Stromversorgung der Gasentladungslampen erfolgt dabei über an den Stirnseiten der Leuchten angeordnete Fassungen, die jeweils in einer Haltevorrichtung - dem sog. Fassungshalter - angeordnet sind. Dabei ist es auch bekannt, in einer Leuchte zwei Gasentladungslampen parallel nebeneinander anzuordnen, um die von der Leuchte abgegebene Lichtmenge insgesamt zu erhöhen.Luminaires with elongated gas discharge lamps are known in a variety of forms. The holder and power supply of the gas discharge lamps takes place via arranged on the end faces of the lights versions, each in a holding device - the so-called. - Holder are arranged. It is also known to arrange two gas discharge lamps in parallel side by side in a lamp to increase the amount of light emitted by the lamp in total.

Bei solchen zweiflammigen Leuchten sind die Fassungshalter in der Regel derart ausgebildet, dass die Fassungen für die Gasentladungslampen und damit die Gasentladungslampen selbst sehr eng beieinander liegen. Diese eng aneinanderliegende Anordnung wird deshalb gewählt, da zum einen auf diese Weise Platz gespart wird und zum anderen die beiden Gasentladungslampen als eine nahezu einheitliche Lichtquelle erscheinen. Auf der anderen Seite bringt diese enge Anordnung den Nachteil mit sich, dass sich die beiden Gasentladungslampen gegenseitig stark erwärmen, was insbesondere bei Leuchtstoffröhren mit der Folge verbunden ist, dass der Wirkungsgrad der Lampen und damit die Lichtausbeute sinkt.In such two-lamp lights, the frame holders are usually designed such that the sockets for the gas discharge lamps and thus the gas discharge lamps themselves are very close together. This close-fitting arrangement is chosen because on the one hand in this way space is saved and on the other hand, the two gas discharge lamps appear as a nearly uniform light source. On the other hand, this close arrangement has the disadvantage that the two gas discharge lamps heat each other strongly, which is particularly associated with fluorescent tubes with the result that the efficiency of the lamps and thus the luminous efficacy decreases.

Demzufolge wäre es wünschenswert, Fassungshalter für jeweils zwei Gasentladungslampen-Fassungen zu verwenden, bei denen die Fassungen und damit die beiden Gasentladungslampen einen größeren Abstand voneinander aufweisen. Durch den größeren Abstand würde nämlich der Wirkungsgrad der Gasentladungslampen wie zuvor erläutert steigen. Da jedoch die derzeit verwendeten zweiflammigen Fassungshalter in überwiegender Anzahl eng beieinander liegende Fassungen aufweisen, wäre es ferner auch wünschenswert, den neu zu konstruierenden Fassungshalter derart auszubilden, dass er in einen Zustand versetzt werden kann, der den bisher verwendeten Fassungshaltern entspricht. Dies ist deshalb wünschenswert, da das Bestücken der Fassungshalter mit den Lampenfassungen sowie das anschließende Befestigen an den Tragelementen der Leuchten automatisch, d.h. mit Robotern oder entsprechend ausgebildeten Werkzeugen erfolgt. Um diese teuren Hilfsmittel auch für den Fassungshalter mit den weiter auseinander liegenden Lampenfassungen verwenden zu können, müsste er in eine Montageposition gebracht werden können, die derjenigen der bisherigen Fassungshalter entspricht.Accordingly, it would be desirable to use socket holders for every two gas discharge lamp sockets in which the sockets and thus the two gas discharge lamps have a greater distance from each other. The greater distance would increase the efficiency of the gas discharge lamps as explained above. However, since the currently used dual-lamp holder holders have a predominantly number of closely spaced versions, it would also be desirable to design the newly designed socket holder such that it can be placed in a state that corresponds to the previously used socket holders. This is desirable because the loading of the socket holder with the lamp holders and the subsequent attachment to the support elements of the lights automatically, ie with robots or trained accordingly Tools done. In order to use these expensive tools for the holder with the lamp sockets further apart, he would have to be able to be brought into a mounting position that corresponds to that of the previous frame holder.

Eine Ansatz zur Lösung dieses Problems ist in der GB 577,239 beschrieben. Diese Patentschrift beschreibt einen Fassungshalter, der aus einem kastenförmigen Grundkörper besteht, an dem Trägerarme zum Halten jeweils einer Fassung für eine Gasentladungslampe befestigt werden können. Bei einer speziellen Variante besteht die Möglichkeit, die Trägerarme entlang einer gekrümmten Führungsnut zu verschieben, d. h. aus einem Zustand, in dem sie eng beieinander liegen, in einen Zustand zu überführen, in dem sie einen weiteren Abstand voneinander aufweisen. Der erste Zustand, in dem die Trägerarme eng beieinander liegen, könnte dann als Montageposition genutzt werden, wobei die Trägerarme nach der Bestückung mit den Lampenfassungen in eine Benutzerposition überführt werden, in der sie einen weiteren Abstand voneinander aufweisen.One approach to solving this problem is in the GB 577,239 described. This patent describes a socket holder, which consists of a box-shaped body, can be attached to the support arms for holding a respective socket for a gas discharge lamp. In a special variant, it is possible to move the support arms along a curved guide groove, ie to move from a state in which they are close together in a state in which they have a further distance from each other. The first state in which the support arms are close together, could then be used as a mounting position, the support arms are transferred after the assembly with the lamp holders in a user position in which they have a further distance from each other.

Die in der GB 577,239 beschriebene Schwenkbarkeit der Trägerarme entlang der Führungsnut ermöglicht allerdings lediglich eine geringfügige Vergrößerung des Abstands zwischen den beiden Lampenfassungen, die für die angestrebte Erhöhung des Lampenwirkungsgrads nicht ausreichend ist. Hierbei ist nämlich zusätzlich zu berücksichtigen, dass die Lampenfassungen nach dem Verschwenken einen gewissen Mindestabstand von dem Montagegrund bzw. den Anbauelementen der Leuchte aufweisen müssen, damit eine zu starke Erwärmung der Umgebung der Lampen vermieden wird.The in the GB 577,239 However described pivoting of the support arms along the guide allows only a slight increase in the distance between the two lamp sockets, which is not sufficient for the desired increase in the lamp efficiency. In this case, in addition to take into account that the lamp holders after pivoting must have a certain minimum distance from the mounting surface or the add-on elements of the lamp, so that excessive heating of the environment of the lamps is avoided.

Aus der US 6,102,550 ist eine Haltevorrichtung für zwei Fassungen bekannt, die einen Grundkörper und zwei daran vorgesehene Trägerarme für jeweils eine Fassung aufweist. Um den Abstand zwischen den beiden Fassungen zu ändern, können die Trägerarme aus- und eingeschoben werden. Außerdem weisen die Trägerarme jeweils ein Gelenk auf, so dass durch eine entsprechende Schwenkbewegung die Relativposition der beiden Fassungen weitergehend variiert werden kann.From the US 6,102,550 a holding device for two versions is known, which has a base body and two support arms provided thereon, each for a socket. To change the distance between the two sockets, the support arms can be extended and retracted. In addition, the support arms each have a joint, so that the relative position of the two versions can be further varied by a corresponding pivoting movement.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, eine Haltevorrichtung zum Halten von zwei Fassungen für Gasentladungslampen anzugeben, bei der eine größere Veränderung des Abstands zwischen den beiden Lampenfassungen möglich ist.Therefore, the present invention has for its object to provide a holding device for holding two sockets for gas discharge lamps, in which a larger change in the distance between the two lamp sockets is possible.

Die Aufgabe wird durch eine Haltevorrichtung, welche die Merkmale des Anspruchs 1 aufweist, gelöst.The object is achieved by a holding device, which has the features of claim 1.

Die Haltevorrichtung gemäß der vorliegenden Erfindung besteht aus einem Grundkörper sowie zwei an dem Grundkörper angeordneten Trägerarmen zum Halten jeweils einer Fassung für eine Gasentladungslampe. Die Trägerarme sind jeweils gegenüber dem Grundkörper wahlweise verschwenkbar, wobei zum Erzielen eines größeren Abstands erfindungsgemäß zusätzlich ihre Länge verstellbar ist. Das Verstellen der Länge kann insbesondere dadurch erfolgen, dass die Trägerarme gegenüber dem Grundkörper eine Translationsbewegung durchführen.The holding device according to the present invention consists of a base body and two arranged on the body support arms for holding a respective socket for a gas discharge lamp. The support arms are each optionally pivotable relative to the base body, wherein to achieve a greater distance according to the invention additionally their length is adjustable. The Adjusting the length can be effected in particular by the carrier arms making a translational movement relative to the base body.

Die Translationsbewegung impliziert, dass die beiden Trägerarme selbst jeweils längere Abmessungen aufweisen, als bisher üblich. Aufgrund dieser größeren Länge ist es möglich, den Abstand der beiden Fassungen zueinander weiter zu vergrößern, als dies bei dem Fassungshalter gemäß der GB 577,239 der Fall ist. Insbesondere kann bei der Haltevorrichtung gemäß der vorliegenden Erfindung die zuvor erwähnte erforderliche Mindesthöhe zum Montagegrund leichter eingehalten und trotzdem ein größerer Abstand zwischen den beiden Lampenfassungen erzielt werden.The translational movement implies that the two support arms each have longer dimensions than previously customary. Due to this greater length, it is possible to further increase the distance between the two versions to each other, as in the frame holder according to the GB 577,239 the case is. In particular, in the holding device according to the present invention, the aforementioned minimum required height for mounting reason easier adhered and still a greater distance between the two lamp sockets can be achieved.

Die erfindungsgemäße Haltevorrichtung eröffnet somit die Möglichkeit, die Trägerarme mit den Lampenfassungen von einer ersten Montageposition, die der Anordnung bisheriger Fassungshalter entspricht und in der die Trägerarme mit den Fassungen bestückt werden können, in eine zweite Benutzerposition, in der die Lampenfassungen den gewünschten großen Abstand voneinander aufweisen, zu überführen, wobei die Trägerarme zum Erreichen der Benutzerposition aus der Montageposition gegenüber dem Grundkörper sowohl eine Translationsbewegung als auch eine Schwenkbewegung durchführen. Damit können die bisherigen Werkzeuge zum automatischen Montieren und Bestücken der Fassungshalter auch für die neue Haltevorrichtung verwendet werden.The holding device according to the invention thus opens up the possibility of the support arms with the lamp holders from a first mounting position, which corresponds to the arrangement of previous frame holder and in which the support arms can be fitted with the versions, in a second user position in which the lamp sockets the desired large distance from each other have to transfer, wherein the support arms to achieve the user position from the mounting position relative to the base body perform both a translational movement and a pivoting movement. Thus, the existing tools for automatic mounting and loading the socket holder can also be used for the new holding device.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche. Sie betreffen insbesondere Maßnahmen, welche zum einen eine zuverlässige Durchführung der Translations- und Schwenkbewegung und zum anderen eine Arretierung der Trägerarme zumindest in der Benutzerposition ermöglichen. So sind die Trägerarme gegenüber dem Grundkörper vorzugsweise gleitend gelagert und weisen hierzu jeweils eine längliche Führungsnut auf, in welche ein an dem Grundkörper angeordneter Führungsstift eingreift. An den beiden Enden einer Führungsnut kann dann jeweils eine Rastöffnung angeordnet sein, wobei die von den Fassungen entfernter liegenden Rastöffnungen jeweils die Schwenkachsen für die beiden Trägerarme definieren.Further developments of the invention are the subject of the dependent claims. They relate in particular to measures which on the one hand enable a reliable performance of the translational and pivotal movement and, on the other hand, a locking of the support arms at least in the user position. Thus, the support arms are preferably slidably mounted relative to the base body and for this purpose each have an elongated guide groove into which a guide pin arranged on the base body engages. At the two ends of a guide groove can then be arranged in each case a detent opening, wherein the remote from the sockets lying latching openings in each case define the pivot axes for the two support arms.

Dargestellt ist eine zweiflammige Leuchte 1, die zunächst ein längliches Trägerelement 2 zur Halterung von zwei Leuchtstofflampen 3 aufweist. Die Halterung der Leuchtstofflampen 3 an dem Trägerelement 2 erfolgt mit Hilfe von zwei Haltevorrichtungen 4, die jeweils an den Stirnseiten des Trägerelements 2 angeordnet sind. Jede Haltevorrichtung 4 dient zur Lagerung von jeweils zwei Lampenfassungen 5, in welche die Leuchtstofflampen 3 mit ihren Stirnenden eingesetzt sind.

In der dargestellten Anordnung weisen die Lampenfassungen 5 und damit die Leuchtstofflampen 3 einen verhältnismäßig großen Abstand voneinander auf. Aufgrund dieses großen Abstands wird eine gegenseitige Erwärmung der Leuchtstofflampen 3, die zu einem Abfallen des Lampenwirkungsgrads führen würde, weitestgehend ausgeschlossen. Die Leuchtstofflampen 3 beanspruchen dadurch zwar einen etwas größeren Raum und erscheinen nun nicht mehr als eine einheitliche Lichtquelle, dies wird allerdings durch den Vorteil eines größeren Lampenwirkungsgrads aufgehoben.In the illustrated arrangement, the lamp holders 5 and thus the fluorescent lamps 3 a relatively large distance from each other. Due to this large distance, mutual heating of the fluorescent lamps 3, which would lead to a drop in lamp efficiency, is largely excluded. Although the fluorescent lamps 3 thereby occupy a slightly larger space and now no longer appear as a single light source, this is offset by the advantage of greater lamp efficiency.

Die Fig. 2a und 2b zeigen die erfindungsgemäße Haltevorrichtung 4 in zwei unterschiedlichen Positionen, Fig. 2a in der Montageposition und Fig. 2b in der Fig. 1 entsprechenden Benutzerposition. Die Haltevorrichtung 4 besteht im wesentlichen aus einem Grundkörper 10, an dem zwei Trägerarme 30 befestigt sind, die jeweils eine topfartige Ausnehmung 32 zur Aufnahme einer (hier nicht dargestellten) Lampenfassung aufweisen. Sowohl der Grundkörper 10 als auch die Trägerarme 30 bestehen vorzugsweise aus Kunststoff und können insbesondere im Spritzgußverfahren hergestellt werden.The Fig. 2a and 2b show the holding device 4 according to the invention in two different positions, Fig. 2a in the mounting position and Fig. 2b in the Fig. 1 corresponding user position. The holding device 4 consists essentially of a base body 10 to which two support arms 30 are fixed, each having a cup-shaped recess 32 for receiving a (not shown here) lamp socket. Both the base body 10 and the support arms 30 are preferably made of plastic and can be produced in particular by injection molding.

Die beiden Trägerarme 30 können gegenüber dem Grundkörper 10 eine Translationsbewegung sowie eine Schwenkbewegung durchführen, um zwischen den beiden in den Fig. 2a und 2b dargestellten Positionen zu wechseln. Sie sind in der in Fig. 2a dargestellten Montageposition derart angeordnet, dass die Anordnung der Ausnehmungen 32 den bisher verwendeten Fassungshaltern für zweiflammige Leuchten entspricht. Diese Montageposition wird verwendet, um die Fassungen für die Gasentladungslampen in die Ausnehmungen 32 einzusetzen, die Haltevorrichtung 4 an dem Trägerelement der Leuchte zu befestigen und die Lampenfassungen mit den Stromversorgungsleitungen zu verbinden. All diese Schritte erfolgen automatisch mit Robotern oder entsprechend ausgebildeten Werkzeugen, wobei die für die bisherigen Fassungshalter verwendeten Hilfsmittel wie angestrebt auch für die erfindungsgemäße Haltevorrichtung 4 verwendet werden können.The two support arms 30 can perform relative to the main body 10 a translational movement and a pivoting movement to between the both in the Fig. 2a and 2b change positions shown. They are in the in Fig. 2a shown mounting position arranged such that the arrangement of the recesses 32 corresponds to the previously used holder holders for two-lamp lights. This mounting position is used to insert the sockets for the gas discharge lamps in the recesses 32, to attach the holding device 4 to the support element of the lamp and to connect the lampholders to the power supply lines. All these steps are carried out automatically with robots or appropriately designed tools, wherein the aids used for the previous frame holder can be used as desired for the holding device 4 according to the invention.

Nach dem Bestücken der Haltevorrichtung 4 mit den Lampenfassungen und der Montage an dem Trägerelement der Leuchte kann die Haltevorrichtung 4 in die in Fig. 2b dargestellte Benutzerposition überführt werden, was dadurch erfolgt, dass die beiden Trägerarme 30 gegenüber dem Grundkörper 10 zunächst eine Translationsbewegung nach unten und anschließend eine nach außen gerichtete Schwenkbewegung durchführen.After loading the holding device 4 with the lamp sockets and the mounting on the support element of the lamp, the holding device 4 in the in Fig. 2b shown user position to be transferred, which takes place in that the two support arms 30 relative to the base body 10 first perform a translational movement down and then an outwardly directed pivoting movement.

Die nach unten gerichtete Translationsbewegung bewirkt zunächst eine Verlängerung der Trägerarme 30 und damit eine Vergrößerung des Abstands der Lampenfassungen bzw. der damit verbundenen Gasentladungslampen gegenüber dem Montagegrund. Diese wird zwar nachfolgend durch die seitliche Schwenkbewegung zumindest teilweise wieder aufgehoben wird, als Folge der Translationsbewegung können allerdings die Trägerarme 30 weiter nach außen geschwenkt werden als dies bisher möglich war. Die erfindungsgemäße Haltevorrichtung 4 ermöglicht somit trotz der Tatsache, dass die beiden Lampenfassungen in einer ersten Position sehr eng beieinander liegen, die Einstellung eines verhältnismäßig großen Abstands in der Benutzerposition.The downward translational movement initially causes an extension of the support arms 30 and thus an increase in the distance of the lamp sockets or the associated gas discharge lamps relative to the mounting reason. Although this is subsequently at least partially canceled by the lateral pivoting movement, as a result of the translational movement, however, the support arms 30 can be pivoted further outwards than was previously possible. Thus, despite the fact that the two lampholders are very close together in a first position, the holding device 4 according to the invention makes it possible to set a relatively large distance in the user position.

Die Translations- und Schwenkbewegungen der Trägerarme 30 gegenüber dem Grundkörper 10 werden durch spezielle Ausgestaltungen dieser beiden Bauelemente der erfindungsgemäßen Haltevorrichtung 4 ermöglicht, was nachfolgend anhand der Fig. 3 bis 11 erläutert werden soll.The translational and pivotal movements of the support arms 30 relative to the base body 10 are made possible by special embodiments of these two components of the holding device 4 according to the invention, which is described below with reference to FIG Fig. 3 to 11 should be explained.

Die Fig. 3-6 zeigen zunächst den Aufbau des Grundkörpers 10, Fig. 3 in einer Ansicht von unten und die Fig. 4-6 in unterschiedlichen perspektivischen Darstellungen.The Fig. 3-6 first show the structure of the main body 10, Fig. 3 in a view from below and the Fig. 4-6 in different perspective views.

Der Grundkörper 10 besteht zunächst aus einem kastenförmigen Haltebereich 11 für die Trägerarme 30, von dessen Vorderseite aus sich eine Montagezunge 12 erstreckt. Die Montagezunge 12 dient der Befestigung des Grundkörpers 10 an dem Trägerelement der Leuchte und weist dementsprechend strukturierte Wandabschnitte auf. Ferner sind in den Seitenbereiche der Montagezunge 12 zwei Rastvorsprünge 13 vorgesehen, welche mit entsprechenden Ausnehmungen an dem Trägerelement der Leuchte zusammenwirken und eine Verrastung bewirken. Hierdurch wird ein unbeabsichtigtes Abgleiten des Haltevorrichtung von dem Trägerelement vermieden.The base body 10 initially consists of a box-shaped holding portion 11 for the support arms 30, from the front of which an assembly tongue 12 extends. The mounting tongue 12 serves to fasten the main body 10 to the carrier element of the luminaire and accordingly has structured wall sections. Further, two locking projections 13 are provided in the side regions of the mounting tongue 12, which cooperate with corresponding recesses on the support element of the lamp and cause a latching. As a result, an unintentional sliding of the holding device is avoided by the support member.

Der Haltebereich 11 des Grundkörpers 10 wird durch eine mittig angeordnete Trennwand 14 in zwei Aufnahmebereiche 15 unterteilt, die jeweils der Aufnahme eines der beiden Trägerarme dienen. Die beiden Aufnahmebereiche 15 werden jeweils von vier Seitenwänden 14, 16, 18 und 22 umschlossen, wobei die der Trennwand 14 gegenüberliegenden Stirnwände 16 jeweils eine nach oben gezogene Ausnehmung 17 aufweisen. Die Ausnehmungen 17 ermöglichen das seitliche Verschwenken der Trägerarme 30, wie später ausführlich erläutert wird.The holding region 11 of the main body 10 is divided by a centrally arranged partition wall 14 into two receiving regions 15, which each serve to receive one of the two carrier arms. The two receiving areas 15 are each enclosed by four side walls 14, 16, 18 and 22, wherein the partition wall 14 opposite end walls 16 each have an upwardly drawn recess 17. The recesses 17 allow the lateral pivoting of the support arms 30, as will be explained in detail later.

An den der Montagezunge 12 zugewandten Seitenwänden 18 der Aufnahmebereiche 15 ist jeweils eine kreisförmige Rastöffnung 19 angeordnet, die durch eine in der Seitenwand 18 verlaufende Vertiefung 20 zur Oberseite der Seitenwand 18 hin fortgeführt ist. Darüber hinaus befinden sich an dieser Wand 18 im unteren Bereich angeordnete Rastvorsprünge 21, die in den Innenraum der Aufnahmebereiche 15 ragen und eine Arretierung der seitlich herausgeschwenkten Trägerarme 30 in der Benutzerposition ermöglichen. An der der Seitenwand 18 gegenüberliegenden Rückwand 22 befinden sich ferner in Höhe der zuvor beschriebenen Rastöffnung 19 ein kreisförmiger, nach innen ragender Führungsstift 23 sowie - gegenüberliegend von dem Rastvorsprung 21 - ein weiterer, schräg angeordneter Rastvorsprung 24, der ebenfalls der Arretierung der Trägerarme in der Benutzerposition dient.At the assembly of the tongue 12 facing side walls 18 of the receiving areas 15 each have a circular detent opening 19 is arranged, which is continued by a recess 20 extending in the side wall 18 to the top of the side wall 18. In addition, located on this wall 18 arranged in the lower region latching projections 21 which protrude into the interior of the receiving areas 15 and allow locking of the laterally swung-out support arms 30 in the user position. On the opposite side wall 18 of the rear wall 22 are also in the amount of the previously described detent opening 19, a circular, inwardly projecting guide pin 23 and - opposite of the locking projection 21 - another, obliquely arranged locking projection 24, which is also the locking of the support arms in the User position serves.

Die Ausgestaltung der Trägerarme 30 soll nunmehr anhand der Fig. 7-11 erläutert werden.The design of the support arms 30 will now be based on the Fig. 7-11 be explained.

Grundsätzlich gesehen besteht ein Trägerarm 30 aus einem länglichem Arm 31, an dessen einem Ende eine topfartige Ausnehmung 32 zur Aufnahme einer Lampenfassung angeordnet ist. Die Ausnehmung 32 weist im vorliegenden Fall die Kontur einer üblichen Leuchtstofflampen-Fassung auf, wobei in den Seitenwänden Öffnungen 33 und 34 angeordnet sind, welche ein Einsetzen der Fassung bzw. ein späteres Entfernen aus der Ausnehmung 32 erleichtern.In principle, a carrier arm 30 consists of an elongate arm 31, at one end of a pot-shaped recess 32 is arranged for receiving a lamp holder. The recess 32 has in the present case, the contour of a conventional fluorescent lamp socket, wherein in the side walls openings 33 and 34 are arranged, which facilitate insertion of the socket or a later removal from the recess 32.

Die Vorderseite 35 des Arms 31 weist einen kreisförmigen Rastvorsprung 36 sowie zwei parallelogrammartig ausgebildete Rastausnehmungen 37 auf. Die Rastausnehmungen 37 sind zu beiden Seiten der Mittelachse des Trägerarms 30 spiegelbildlich zueinander angeordnet, was den Vorteil hat, dass der hierdurch symmetrisch ausgebildete Trägerarm 30 sowohl auf der linken als auch auf der rechten Seite des Grundkörpers 10 angeordnet werden kann. Es muss dementsprechend lediglich eine Art von Trägerarmen 30 bereit gestellt werden, wodurch der Aufwand bei der Montage der Haltevorrichtung erheblich reduziert wird.The front side 35 of the arm 31 has a circular latching projection 36 and two parallelogram-shaped latching recesses 37. The latching recesses 37 are arranged on both sides of the central axis of the support arm 30 mirror images of each other, which has the advantage that the thus symmetrically formed support arm 30 can be arranged on both the left and on the right side of the body 10. Accordingly, only one type of support arms 30 has to be provided, as a result of which the outlay on assembly of the holding device is considerably reduced.

An der der Vorderseite 35 gegenüberliegenden Rückseite 38 befinden sich zunächst zwei mittig angeordnete kreisförmige Rastöffnungen 39a und 39b, wobei die erste Rastöffnung 39a in Höhe des Rastvorsprungs 36 der Vorderseite 35 und die zweite Rastöffnung 39b in etwa in Höhe der beiden Rastausnehmungen 37 angeordnet ist. Beide Rastöffnungen 39a und 39b sind über eine an der Außenseite der Rückwand 38 verlaufende Führungsnut 40 miteinander verbunden. Zu beiden Seiten der unteren Rastöffnung 39b sind ferner zwei Rastschlitze 41 angeordnet, wobei die beidseitige Anordnung wiederum aufgrund der zuvor erläuterten angestrebten Symmetrie des Trägerarms 30 erfolgt.At the rear side 38 opposite the front side 35 there are initially two centrally arranged circular detent openings 39a and 39b, the first detent opening 39a being at the level of the detent projection 36 of the front side 35 and the second detent opening 39b approximately at the level of the two detent recesses 37. Both latching openings 39a and 39b are connected to one another via a guide groove 40 extending on the outside of the rear wall 38. On both sides of the lower detent opening 39b two locking slots 41 are also arranged, wherein the two-sided arrangement again takes place on the basis of the previously described desired symmetry of the support arm 30.

Wie insbesondere Fig. 11 zu entnehmen ist, befinden sich an den Innenseiten der beiden Schmalwände 42 des Arms 31 Durchgangsöffnungen 43, die sich von der oberen Stirnseite des Arms 31 bis zu der Ausnehmung 32 für die Lampenfassung erstrecken und letztendlich in diese münden. Diese Durchgangsöffnungen 43 dienen der Führung von Drähten um die Lampenfassungen mit den Stromversorgungsleitungen der Leuchte zu verbinden.In particular Fig. 11 can be seen, are located on the insides of the two narrow walls 42 of the arm 31 through openings 43 which extend from the upper end face of the arm 31 to the recess 32 for the lamp holder and ultimately open into this. These passage openings 43 are used to guide wires to connect the lamp sockets with the power supply lines of the lamp.

Im Folgenden soll dass Zusammenwirken der verschiedenen Rastausnehmungen bzw. Rastvorsprüngen des Grundkörpers 10 und der Trägerarme 30 während der Positionsveränderung der Trägerarme 30 erläutert werden.In the following, the interaction of the various latching recesses or latching projections of the base body 10 and the support arms 30 during the change in position of the support arms 30 will be explained.

In der in Fig. 2a dargestellten Montageposition befinden sich die beiden Trägerarme 30 in einer eng beieinanderliegenden Position, wobei sie senkrecht angeordnet sind. In dieser Stellung greifen die Führungsstifte 23 des Grundkörpers 10 jeweils in die unteren Rastöffnungen 39b an den Rückwänden 38 der Trägerarme 30 ein. Durch diesen Eingriff ist ein leichtes Verrasten der Trägerarme 30 mit dem Grundkörper 10 gewährleistet. Da ferner die Seitenwände der Ausnehmungen 32 der Trägerarme 30 an der Trennwand 14 sowie an den Unterkanten der Rastvorsprünge 21 und 24 des Grundkörpers 10 anliegen, ist auch eine seitliche Fixierung der Trägerarme 30 gewährleistet. Insgesamt gesehen werden damit die beiden Trägerarme 30 in der in Fig. 2a dargestellten Montageposition gehalten, wodurch eine Bestückung mit Lampenfassungen, elektrische Kontaktierung und Befestigung der Haltevorrichtung 4 an dem Trägerelement der Leuchte ermöglicht wird.In the in Fig. 2a illustrated mounting position, the two support arms 30 are in a close-spaced position, wherein they are arranged vertically. In this position, the guide pins 23 of the main body 10 respectively engage in the lower detent openings 39b on the rear walls 38 of the support arms 30. By this engagement, a slight locking of the support arms 30 is ensured with the main body 10. Further, since the side walls of the recesses 32 of the support arms 30 abut against the partition wall 14 and at the lower edges of the latching projections 21 and 24 of the base body 10, is also a lateral fixation of the support arms 30th guaranteed. Overall, so that the two support arms 30 in the in Fig. 2a held mounting position, whereby a fitting with lamp holders, electrical contact and attachment of the holding device 4 is made possible on the support element of the lamp.

Um die Trägerarme 30 nunmehr in die in Fig. 2b dargestellte Benutzerposition zu überführen, müssen sie zunächst in einer Translationsbewegung senkrecht nach unten bewegt werden, wobei die Verrastung zwischen den Führungsstiften 23 und den Rastöffnungen 39b ohne größeren Kraftaufwand gelöst werden kann.To the support arms 30 now in the in Fig. 2b To transfer shown user position, they must first be moved vertically downward in a translational movement, the latching between the guide pins 23 and the locking holes 39 b can be solved without much effort.

Während dieser Translationsbewegung gleitet der Führungsstift 23 des Grundkörpers 10 entlang der Führungsnut 40 des Trägerarms 30, bis er in die obere Rastöffnung 39a eingreift. Zu diesem Zeitpunkt greift ferner auch der an dem Trägerarm 30 angeordnete Rastvorsprung 36 in die Öffnung 19 an der Wand 18 des Grundkörpers 10 ein, nachdem er zunächst entlang der Führungsnut 20 des Grundkörpers geführt wurde.During this translational movement of the guide pin 23 of the body 10 slides along the guide groove 40 of the support arm 30 until it engages in the upper detent opening 39a. At this time, furthermore, the latching projection 36 arranged on the carrier arm 30 also engages in the opening 19 on the wall 18 of the base body 10, after it has first been guided along the guide groove 20 of the base body.

Bei Abschluss der Translationsbewegung greifen somit jeweils die Führungsstifte 23 bzw. Rastvorsprünge 36 in die entsprechenden Ausnehmungen 19 und 39a ein, wodurch eine sichere Halterung des Trägerarms 30 an dem Grundkörper 10 gewährleistet ist. Die Vorsprünge 23 und 36 bzw. Ausnehmungen 19 und 39a definieren ferner zwei Schwenkachsen, um welche nunmehr die beiden Trägerarme 30 seitlich nach außen geschwenkt werden können, wobei sie hierbei jeweils in die Ausnehmungen 17 der Seitenwände 16 des Grundkörpers 10 einschwenken.When the translational movement is completed, the guide pins 23 and / or latching projections 36 thus engage in the corresponding recesses 19 and 39a, thereby ensuring secure holding of the carrier arm 30 on the base body 10. The projections 23 and 36 or recesses 19 and 39a further define two pivot axes about which now the two support arms 30 can be pivoted laterally outwards, in which case they each pivot into the recesses 17 of the side walls 16 of the base body 10.

Die Trägerarme 30 werden dabei jeweils soweit nach außen geschwenkt, bis sie mit ihren Seitenwänden 42 in Anlage zu den Oberkanten der Ausnehmungen 17 gelangen. Diese sind derart bemessen, dass in dieser Position ferner auch die Rastvorsprünge 21 und 24 des Grundkörpers 10 in die jeweils zur Mitte des Grundkörpers 10 hin orientierten Ausnehmungen 37 und 41 des Trägerarms 30 eingreifen. Dieser Eingriff bewirkt eine feste Arretierung der Trägerarme 30 in der in Fig. 2b dargestellten Benutzerposition, durch die ein unbeabsichtigtes Verschwenken der Trägerarme 30 ausgeschlossen wird.The support arms 30 are in each case pivoted so far outward until they come with their side walls 42 in abutment with the upper edges of the recesses 17. These are dimensioned such that in this position, furthermore, the latching projections 21 and 24 of the base body 10 in the recesses 37 and 41 of the support arm 30 oriented toward the center of the main body 10, respectively. This engagement causes a firm locking of the support arms 30 in the in Fig. 2b shown user position, by the unintentional pivoting of the support arms 30 is excluded.

Anzumerken ist, dass jeweils nur die zur Mitte des Grundkörpers 10 hin orientierten Ausnehmungen 37 und 41 der Trägerarme 30 mit den entsprechenden Vorsprüngen 21 und 24 des Grundkörpers 10 verrasten. Die jeweils außen liegenden Ausnehmungen 37 und 41 sind hingegen funktionslos. Dennoch ist die zur jeweiligen Mittelachse symmetrische Anordnung der Rast- und Führungselemente der Trägerarme 30 - also der Ausnehmungen 37, 41, des Vorsprungs 36, der Öffnungen 39a, 39b sowie der Führungsnut 40 - von Vorteil, da hierdurch ein Trägerarm 30 an beiden Seiten des Grundkörpers 10 angeordnet werden kann.It should be noted that in each case only the recesses 37 and 41 of the carrier arms 30 which are oriented towards the center of the main body 10 engage with the corresponding projections 21 and 24 of the main body 10. The respective outer recesses 37 and 41, however, are inoperative. Nevertheless, the symmetrical to the respective central axis arrangement of the locking and guiding elements of the Carrier arms 30 - so the recesses 37, 41, the projection 36, the openings 39 a, 39 b and the guide groove 40 - of advantage, as a carrier arm 30 can be arranged on both sides of the body 10 thereby.

Die erfindungsgemäße Haltevorrichtung 4 kann somit durch einfache und wenige Handgriffe aus der Montageposition in die Benutzerposition überführt werden. Da die Arretierung der beiden Trägerarme 30 in den verschiedenen Positionen sowie die Führung während der Translations- und Schwenkbewegung ausschließlich durch die an dem Grundkörper 10 und den Trägerarmen 30 angeordneten Rast- und Führungselemente erfolgt, sind auch keine zusätzlichen Bauteile erforderlich, um die gewünschten Funktionen zu erzielen.The holding device 4 according to the invention can thus be transferred by simple and few handles from the mounting position to the user position. Since the locking of the two support arms 30 in the various positions as well as the guide during the translation and pivoting movement takes place exclusively by the arranged on the base body 10 and the support arms 30 locking and guide elements, no additional components are required to the desired functions achieve.

Die vorliegende Haltevorrichtung zeichnet sich somit insbesondere auch durch ihren einfachen und kostengünstigen Aufbau aus. Gleichzeitig bietet sie die Möglichkeit, die Lampenfassungen und damit die Gasentladungslampen nach einer automatisch durchgeführten Montage in einem sehr weiten Abstand voneinander anzuordnen und damit den Lampenwirkungsgrad zu erhöhen.The present holding device is thus characterized in particular by its simple and inexpensive construction. At the same time it offers the possibility of arranging the lamp sockets and thus the gas discharge lamps after an automatically performed assembly at a very large distance from each other and thus to increase the lamp efficiency.
