Abstract

Various accessories are to be able to be fastened to a ceiling light fixture in a simple and reliable manner, without adjustment and with tools which are as simple as possible. The ceiling light fixture (2) has a cover ring (6) with an edge groove (62). A mounting (10) which has a clamp-like upper part (13) can be suspended in this edge groove. A lower part (14) of the mounting is constructed to have the shape of a shoe and rests against the outside of the cover ring. The mounting parts have centring surfaces (133 respectively 145), which are constructed with mirror-image symmetry and are at a slight angle with respect to each other, and become tensioned against one another during assembly so as to bear against the cover ring in a tolerance-free manner. A spacer block (9) is constructed so as to be placable into the mounting (10) and a clamping element (11) for accommodating an accessory (7) is constructed so as to be placable and secure against rotation. The fastening device is thus self-adjusting. The fastening device can be used, in particular for interior spaces, for luminaires which are attached, for surface-type luminaires and built-in luminaires. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Einrichtung zum Befestigen von Zubehörteilen an einer Deckenleuchte in einem vorgegebenen Abstand gemäß dem Oberbegriff des Patentanspruches 1. Vergleichbare Einrichtungen sind z.B. aus DE-C-493 015 oder aus GB-A-383 145 bekannt.The invention relates to a device for attaching accessories to a ceiling lamp at a predetermined distance according to the preamble of claim 1. Comparable devices are e.g. known from DE-C-493 015 or from GB-A-383 145.

Es ist in einer Vielzahl von Anwendungsfällen bekannt, an Deckenleuchten, wie z. B. Strahlern oder auch Deckenanbau- bzw. Deckeneinbauleuchten in einem vorgegebenen Abstand Zubehörteile zu befestigen. Solche Zubehörteile können Elemente sein, die ohne eine wesentliche lichttechnische Funktion vorwiegend als Gestaltungselemente dienen, die den optischen Eindruck der jeweiligen Leuchte hervorheben soll. In vielen Fällen aber haben derartige Zubehörteile vor allem eine lichttechnische Funktion. Je nach ihrem Zweck können solche Zubehörteile unterschiedliche Formen aufweisen, sie können beispielsweise als plane Platten, Ringe oder auch Kegel ausgebildet sein, die als Blickfang dienen und oder das von der Leuchte ausgestrahlte Licht formen, um beispielsweise einen die Deckenleuchte umgebenden Flächenbereich der Decke aufzuhellen. Diese Beispiele umreißen die vielfältigen Anwendungs- und Gestaltungsmöglichkeiten, bei denen an die Deckenleuchte angehängte Zubehörteile verwendet werden.It is known in a variety of applications, on ceiling lights, such as. B. spotlights or ceiling or recessed ceiling lights to attach accessories at a predetermined distance. Such accessories can be elements which, without an essential lighting function, primarily serve as design elements which are intended to emphasize the optical impression of the respective luminaire. In many cases, however, such accessories have primarily a lighting function. Depending on their purpose, such accessories can have different shapes, for example they can be designed as flat plates, rings or cones, which serve as eye-catchers and or shape the light emitted by the lamp, for example to lighten a surface area of the ceiling surrounding the ceiling lamp. These examples outline the diverse application and design options in which accessories attached to the ceiling light are used.

Um Zubehörteile an einer Deckenleuchte in einem vorgegebenen Abstand zu befestigen, wird eine entsprechende Einrichtung benötigt. Diese besteht aus einem oder mehreren Distanzstücken, beispielsweise Rundstäben, die endseitig an der Deckenleuchte z. B. durch eine Schraub- oder Schweißverbindung lösbar bzw. unlösbar festgelegt sind. Am leuchtenfernen Ende des Distanzstückes bzw. der Distanzstücke ist dann das Zubehörteil beispielsweise ebenfalls durch eine Schraubverbindung festgelegt. In manchen Anwendungsfällen gehören zu einem Leuchtenprogramm verschiedene Zubehörteile, die alternativ eingesetzt werden können. Auch ist es aus Gründen des einfacheren Versandes häufig wünschenswert, die Deckenleuchte, ein Zubehörteil sowie die zugehörige Befestigungsvorrichtung unmontiert zu verschicken. In all diesen Fällen ist zu fordern, daß Montage oder auch Demontage des Zubehörteiles möglichst einfach und ohne aufwendiges Werkzeug zu bewerkstelligen ist.In order to attach accessories to a ceiling lamp at a specified distance, an appropriate device is required. This consists of one or more spacers, for example round rods, the ends of the ceiling lamp z. B. are detachable or non-detachable by a screw or welded connection. At the distant end of the spacer or spacers, the accessory is then also fixed, for example, by a screw connection. In some use cases a range of accessories that can be used alternatively. For reasons of easier shipping, it is also often desirable to send the ceiling light, an accessory and the associated fastening device unmounted. In all of these cases, it must be demanded that assembly or disassembly of the accessory is as simple as possible and without the need for expensive tools.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, für eine Einrichtung der eingangs genannten Art eine weitere Lösung anzugeben, mit der sich ein Zubehörteil an einer Deckenleuchte sicher, einfach und vor allem auch ohne wesentlichen Justieraufwand, gegebenenfalls auch durch einen Ungeübten, ohne komplizierte Montageanleitung durchführen läßt.The present invention is therefore based on the object of specifying a further solution for a device of the type mentioned at the outset, with which an accessory on a ceiling light can be carried out safely, simply and above all without any substantial adjustment effort, possibly also by an inexperienced person, without complicated assembly instructions leaves.

Bei einer Einrichtung der eingangs genannten Art wird diese Aufgabe erfindungsgemäß durch die im Kennzeichen des Patentanspruches 1 beschriebenen Merkmale gelöst.In a device of the type mentioned, this object is achieved according to the invention by the features described in the characterizing part of patent claim 1.

Dabei ist die leuchtenseitige Aufnahme der Einrichtung als Abdeckring ausgebildet, in den eine Halterung so eingehängt wird, daß sie im montierten Zustand den Umfang dieses Abdeckringes klemmend umfaßt. Sie ist so ausgebildet, daß sie sich beim Verspannen toleranzfrei an den Abdeckring anlegt und dabei selbst gegenüber der Deckenleuchte ausrichtet. Dazu ist die Halterung zweiteilig ausgebildet. Sie besitzt ein den Rand des Abdeckringes umgreifendes, als Klammer ausgebildetes, hakenförmiges Oberteil und ein schuhförmiges Unterteil, das sich beim Verbinden dieser beiden Teile mit seiner Vorderseite gegen die Unterseite des Abdeckringes anlegt. Die klammernde Wirkung dieser beiden Halterteile wird dadurch erreicht, daß eine ihrer beiden gegenseitigen Berührungsflächen um wenige Winkelgrade angeschrägt ist, so daß beim Verbinden dieser beiden Teile eine leichte zangenförmige Bewegung auftritt, mit der die beiden Halterteile den Abdeckring umfassen. Neben dieser einfachen Montagemöglichkeit besteht ein wesentlicher Vorteil dieser Einrichtung gegenüber an sich bekannter Lösungen zum Befestigen von Zubehörteilen in der Optimierung der Anzahl von Einzelteilen eines Leuchtenprogrammes. Auch bei bekannten Leuchten werden Abdeckringe als solche häufig eingesetzt. Werden dann Zubehörteile mittels Schraubverbindungen am Abdeckring befestigt, so sind für einen Leuchtentyp zwei unterschiedliche Abdeckringe im Programm erforderlich, in denen keine bzw. die nötigen Aufnahmebohrungen vorgesehen sind. Auch ist es dann ohne Austausch des Abdeckringes nicht möglich, ein und dieselbe Leuchte wahlweise mit Zubehörteilen zu bestücken bzw. Zubehörteile im nachhinein anzubringen. Die erfindungsgemäße Lösung verringert damit auch den Herstellungs- und Lagerhaltungsaufwand des Herstellers und ist wesentlicher flexibler in bezug auf Kundenanforderungen.The light-side receptacle of the device is designed as a cover ring, in which a holder is hung so that it encompasses the circumference of this cover ring in a clamped state. It is designed in such a way that when it is braced, it rests on the cover ring without tolerances and aligns itself with the ceiling light. For this purpose, the bracket is formed in two parts. It has a hook-shaped upper part encompassing the edge of the cover ring, designed as a clamp, and a shoe-shaped lower part which, when these two parts are connected, lies against the underside of the cover ring with its front side. The clinging effect of these two holder parts is achieved in that one of their two mutual contact surfaces is chamfered by a few angular degrees, so that when these two parts are connected there is a slight pincer-shaped movement with which the two holder parts enclose the cover ring. In addition to this simple installation option, there is a Significant advantage of this device compared to known solutions for fastening accessories in the optimization of the number of individual parts of a lighting program. Cover rings as such are also frequently used in known lights. If accessories are then attached to the cover ring by means of screw connections, two different cover rings are required in the program for a type of luminaire, in which no or the necessary mounting holes are provided. Even without replacing the cover ring, it is then not possible to equip one and the same lamp with accessories or to attach accessories afterwards. The solution according to the invention thus also reduces the manufacturing and storage costs of the manufacturer and is considerably more flexible with regard to customer requirements.

Weiterbildungen der Erfindung sind in Unteransprüchen definiert.Further developments of the invention are defined in subclaims.

In Figur 1 ist eine in eine Decke 1 eingesetzte Einbauleuchte 2 dargestellt. Einzelheiten der Ausgestaltung einer solchen Leuchte sind im vorliegenden Fall lediglich von untergeordnetem Interesse. Deshalb ist hier schematisch lediglich eine mit ihrem Lampenkolben in den Ausschnitt eines haubenförmigen Reflektors 3 eingesetzte Lampe 4 angedeutet. Die Lichtaustrittsöffnung der Deckenleuchte 2 ist durch eine lichtdurchlässige Scheibe 5 abgedeckt, die als Filter und/oder als Streuscheibe ausgebildet sein kann. Als Abschluß gegen die Decke dient ein die Scheibe 5 umgreifender Abdeckring 6. Insoweit ist die in Figur 1 dargestellte Deckenleuchte 2 an sich lediglich ein Beispiel für eine Vielzahl von bekannten Deckenleuchten, die als Deckenanbauleuchten, Deckeneinbauleuchten, aber auch als Deckenaufbauleuchten handelsüblich sind.1 shows a recessed luminaire 2 inserted into a ceiling 1. Details of the design of such a lamp are only of minor interest in the present case. Therefore, only one lamp 4 inserted with its lamp bulb into the cutout of a hood-shaped reflector 3 is indicated schematically here. The light exit opening of the ceiling lamp 2 is covered by a translucent pane 5, which can be designed as a filter and / or as a diffuser. A cover ring 6 encompassing the disc 5 serves as a closure against the ceiling. In this respect, the ceiling light 2 shown in FIG. 1 is in itself only an example of a large number of known ceiling lights, which are commercially available as surface-mounted ceiling lights, recessed ceiling lights, but also as ceiling-mounted lights.

Eine erste Besonderheit der in Figur 1 dargestellten Leuchtenform liegt in der Ausgestaltung des Abdeckringes 6. Er schließt nicht nur an die Decke 1 an, um den für den Einsatz der Leuchte notwendigen Deckenausschnitt abzudecken, sondern weist darüber hinaus zumindestens in Teilbereichen einen Randwulst 61 auf, der seitlich nach außen hervorsteht. In die der Decke 1 zugekehrte Oberseite dieses Randwulstes 61 ist eine Randnut 62 eingelassen. Außerdem ist die von der Decke 1 abgewandte Unterseite des Abdeckringes 6 als geneigte Schrägfläche 63 ausgebildet.A first special feature of the luminaire shape shown in FIG. 1 lies in the design of the cover ring 6. It not only adjoins the ceiling 1 in order to cover the ceiling cutout required for the use of the luminaire, but also has an edge bead 61 at least in some areas, that protrudes laterally outwards. An edge groove 62 is embedded in the top of this edge bead 61 facing the ceiling 1. In addition, the underside of the cover ring 6 facing away from the ceiling 1 is designed as an inclined inclined surface 63.

Es ist nun nicht ungewöhnlich für solche Deckenleuchten Zubehörteile vorzusehen, die in einem bestimmten Abstand unterhalb der Deckenleuchte anzuordnen sind. Solche Zubehörteile können als funktional die Wirkung der Deckenleuchte mitbestimmende Elemente, d. h. lichttechnisch wirksame Elemente ausgebildet sein, sie können aber auch reine Gestaltungselemente ohne eine lichttechnische Funktion sein, die die Deckenleuchte in ihrem Eindruck auf den Betrachter hervortreten lassen. Daraus ergibt sich eine Vielzahl von möglichen Gestaltungsformen solcher Zubehörteile, die hier als solche ebenso von untergeordneter Bedeutung sind. Deshalb ist in Figur 1 als ein Beispiel für ein solches Zubehörteil in unterbrochenen Linien ein unterhalb der Deckenleuchte 2 abgehängter Ring 7 angedeutet, der wie einige schematisch eingezeichnete Lichtstrahlen 81 bzw. 82 zeigen, auftreffendes Licht teilweise durchläßt bzw. in Randbereichen zur Aufhellung der Decke 1 in der Umgebung der Deckenleuchte 2 reflektiert.It is now not uncommon to provide accessories for such ceiling lights that are to be arranged at a certain distance below the ceiling light. Such accessories can functionally determine the effect of the ceiling light, i.e. H. lighting technically effective elements can be formed, but they can also be pure design elements without a lighting function, which let the ceiling light emerge in its impression on the viewer. This results in a variety of possible forms of design of such accessories, which as such are also of minor importance here. For this reason, a ring 7 suspended below the ceiling light 2 is indicated in broken lines in FIG. 1 as an example of such an accessory, which, as some schematically illustrated light beams 81 and 82 show, partially passes incident light or in peripheral areas for brightening the ceiling 1 reflected in the vicinity of the ceiling lamp 2.

Diese Ausführungsform eines Zubehörteiles als Ring 7 ist aber lediglich beispielhaft zu verstehen und zur Illustration stellvertretend für eine Vielzahl von Gestaltungsmöglichkeiten ausgewählt.However, this embodiment of an accessory as ring 7 is only to be understood as an example and is selected for illustration as representative of a large number of design options.

Wesentlicher dagegen ist, wie dieses Zubehörteil 7 unterhalb der Deckenleuchte 2 abgehängt ist, d. h. wie die Einrichtung zum Befestigen dieses Zubehörteiles 7 zur Deckenleuchte 2 ausgestaltet ist. Diese Einrichtung besteht aus einem stangenförmigen Distanzstück 9, an dessen der Deckenleuchte 2 zugekehrtem Ende eine zweiteilige Halterung 10 festgelegt ist. Am anderen Ende des Distanzstückes 9 ist ein Klemmelement 11 zum Aufnehmen des entsprechenden Zubehörteiles vorgesehen. Diese Einrichtung zum Befestigen von Zubehörteilen an einer Deckenleuchte 2 in einem vorgegebenen Abstand kann mit einem Stativ verglichen werden, das in einer zur Deckenleuchte 2 asymmetrischen Anordnung das Zubehörteil 7 trägt.What is more important, however, is how this accessory 7 is suspended below the ceiling lamp 2, ie how the device for fastening this accessory 7 to the ceiling lamp 2 is designed. This device consists of a rod-shaped spacer 9, at the end facing the ceiling lamp 2, a two-part bracket 10 is fixed. At the other end of the spacer 9, a clamping element 11 is provided for receiving the corresponding accessory. This device for attaching accessories to a ceiling lamp 2 at a predetermined distance can be compared to a tripod which carries the accessory 7 in an arrangement asymmetrical to the ceiling lamp 2.

In Figur 2 ist in einem gegenüber der Darstellung von Figur 1 vergrößerten Ausschnitt deutlicher dargestellt, wie diese Einrichtung an dem Abdeckring 6 der Deckenleuchte 2 festgelegt ist. Dieser Ausschnitt verdeutlicht, daß die Halterung 10 zweiteilig ausgebildet ist, d. h. ein als Klammer 13 ausgebildetes Oberteil sowie ein als Schuh 14 ausgebildetes Unterteil aufweist. Klammer 13 und Schuh 14 der Halterung 10 sind durch eine Verbindungsschraube 15, die in eine Gewindebohrung des halterungsseitigen Endes des Distanzelementes 9 eingreift, miteinander verbunden. Wie noch näher zu erläutern sein wird, ist diese Halterung 10 in den Randwulst 61 des Abdeckringes 6 eingehängt, d. h. an diesem form- und kraftschlüssig festgelegt.In FIG. 2, an enlarged detail compared to the representation of FIG. 1 shows more clearly how this device is fixed to the cover ring 6 of the ceiling lamp 2. This section illustrates that the bracket 10 is formed in two parts, i. H. has an upper part designed as a clip 13 and a lower part designed as a shoe 14. Bracket 13 and shoe 14 of the holder 10 are connected to one another by a connecting screw 15 which engages in a threaded bore in the holder-side end of the spacer element 9. As will be explained in more detail, this holder 10 is suspended in the edge bead 61 of the cover ring 6, i. H. on this positively and non-positively.

In den Figuren 3 bis 5 ist die Klammer 13 der Halterung 10 zur Verdeutlichung ihres Aufbaues in je einer Ansicht gezeigt. Die Klammer 13 weist eine Durchgangsbohrung 131 zur Aufnahme der Verbindungsschraube 15 einschließlich ihres Schraubenkopfes auf. In Figur 3 ist am deutlichsten ein hakenförmiger Ansatz 132 der Klammer 13 zu erkennen, dessen Umriß der Form der Randnut 62 des Abdeckringes 6 angepaßt ist. Mit diesem hakenförmigen Ansatz 132 umgreift die Klammer 13 im montierten Zustand den Abdeckring 6 der Deckenleuchte 2 von oben. Der hakenförmige Ansatz 132 und die Randnut 62 des Abdeckringes 6 sind in ihren Abmessungen sorgfältig aufeinander abgestimmt. Vorzugsweise ist der Nutboden der Randnut 62 des Abdeckringes nach außen ansteigend angestellt, wobei diese Neigung des Nutbodens der Randnut 62 in etwa der Neigung der Schrägfläche 63, d. h. der Unterseite des Abdeckringes entspricht. Spiegelbildlich symmetrisch dazu sind die Eingriffsflächen des hakenförmigen Ansatzes 132 der Klammer 13 ausgebildet.In Figures 3 to 5, the bracket 13 of the bracket 10 is shown in each view to illustrate its structure. The bracket 13 has a through hole 131 for receiving the connecting screw 15 including its screw head. A hook-shaped extension 132 of the clamp 13 can be seen most clearly in FIG. 3, the outline of which is adapted to the shape of the edge groove 62 of the cover ring 6. With this hook-shaped extension 132, the clamp 13 engages around the cover ring 6 of the ceiling lamp 2 from above in the assembled state. The dimensions of the hook-shaped extension 132 and the edge groove 62 of the cover ring 6 are carefully coordinated. The groove bottom of the edge groove 62 of the cover ring is preferably inclined to the outside, this inclination of the groove bottom of the edge groove 62 being approximately the inclination of the inclined surface 63, i. H. corresponds to the underside of the cover ring. The engagement surfaces of the hook-shaped extension 132 of the clamp 13 are formed in a mirror-symmetrical manner.

Darüber hinaus ist die Ausgestaltung der Unterseite der Klammer 13, d. h. der Berührungsfläche mit dem Schuh 14 von funktionaler Bedeutung. Diese Unterseite weist einen dachförmig ausgebildeten, mit aus einer Dachkante senkrecht zum hakenförmigen Ansatz 132 stehenden Vorsprung 133 auf. Dieser Vorsprung 133 dient als Zentrierfläche der Klammer 13 gegenüber dem Schuh 14. Betrachtet man die Achse der Durchgangsbohrung 131 der Klammer 13 als Hauptachse der Klammer, so verdeutlicht Figur 3, daß die Giebelkante des dachförmigen Vorsprunges 133 in bezug auf diese Symmetrieachse nicht exakt senkrecht liegt, sondern um einen definierten Neigungswinkel α dagegen angestellt ist. Durch diesen Neigungswinkel α ist bedingt, daß der dachförmige Vorsprung 133 in Richtung auf den hakenförmigen Ansatz 132 der Klammer 13 allmählich flacher wird. Die Bedeutung dieser Einzelheit wird später noch erläutert.In addition, the design of the underside of the clamp 13, ie the contact surface with the shoe 14, is of functional importance. This underside has a roof-shaped, with a roof edge perpendicular to the hook-shaped Approach 132 stand up projection 133. This projection 133 serves as the centering surface of the bracket 13 with respect to the shoe 14. If the axis of the through-hole 131 of the bracket 13 is the main axis of the bracket, FIG. 3 shows that the gable edge of the roof-shaped projection 133 is not exactly vertical with respect to this axis of symmetry , but is set against a defined angle of inclination α. This inclination angle α means that the roof-shaped projection 133 gradually becomes flatter in the direction of the hook-shaped extension 132 of the clamp 13. The meaning of this detail will be explained later.

Analog ist in den Figuren 6 bis 8 jeweils eine Ansicht des Schuhs 14 als dem Unterteil der Halterung 10 dargestellt. Wie der Querschnitt dieses Schuhs in Figur 6 zeigt, weist auch dieser eine zentrale Bohrung auf, die hier allerdings geteilt ist. Der im oberen Teil des Schuhs 14 liegende Bohrungsabschnitt 141 ist exakt kreisförmig und entspricht in seinem Durchmesser dem Durchmesser der Durchgangsbohrung 131 in der Klammer 13 und ist damit dem Schaftdurchmesser der Verbindungsschraube 15 angepaßt. Der untere Bohrungsabschnitt 142 bildet ein Sackloch zur Aufnahme des oberen Endes des Distanzelementes 9. Dieser untere Bohrungsabschnitt 142 ist in seinem Querschnitt als Kreissegment ausgebildet, wie die Unteransicht des Schuhs, dargestellt in Figur 7, am deutlichsten zeigt. Dieser Querschnitt entspricht dem Querschnitt des Distanzelementes 9, d. h. daß auch dieses entsprechend einseitig angefast ist. Damit ist das Distanzelement 9 in bezug auf den Schuh 14 und somit die gesamte Klammer 13 exakt zentriert.Analogously, FIGS. 6 to 8 each show a view of the shoe 14 as the lower part of the holder 10. As the cross-section of this shoe in FIG. 6 shows, it also has a central bore, which is, however, divided here. The bore section 141 located in the upper part of the shoe 14 is exactly circular and corresponds in diameter to the diameter of the through bore 131 in the bracket 13 and is thus adapted to the shaft diameter of the connecting screw 15. The lower bore section 142 forms a blind hole for receiving the upper end of the spacer element 9. This lower bore section 142 is designed in its cross section as a circular segment, as the bottom view of the shoe, shown in FIG. 7, shows most clearly. This cross section corresponds to the cross section of the spacer element 9, i. H. that this is also chamfered accordingly on one side. Thus, the spacer 9 is exactly centered with respect to the shoe 14 and thus the entire bracket 13.

Die Ristfläche 143 des Schuhs, d. h. seine im montierten Zustand der Schrägfläche 63 des Abdeckringes 6 zugekehrte Oberseite ist entsprechend der Neigung dieser Schrägfläche ebenso geneigt ausgebildet. Die Deckfläche 144 des Schuhs 14 schließlich weist, wie in der Seitenansicht von Figur 8 am deutlichsten erkennbar, eine V-förmige Nut 145 auf. Diese V-förmige Nut 145 des Schuhs 14 entspricht spiegelbildlich symmetrisch dem dachförmigen Vorsprung 133 der Klammer 13. Die Klammer 13 und der Schuh 14 sind mit Hilfe dieser beiden Flächen beim Zusammensetzen zueinander zu zentrieren.The instep surface 143 of the shoe, ie its upper side facing the inclined surface 63 of the cover ring 6 in the assembled state, is also inclined in accordance with the inclination of this inclined surface. Finally, the top surface 144 of the shoe 14 has, as in the side view of FIG most clearly recognizable, a V-shaped groove 145. This V-shaped groove 145 of the shoe 14 corresponds mirror-symmetrically to the roof-shaped projection 133 of the bracket 13. The bracket 13 and the shoe 14 are to be centered with one another with the aid of these two surfaces when they are assembled.

In den Figuren 9 bis 11 ist in je einer Ansicht das Klemmelement 11 dargestellt, das am leuchtenfernen Ende des stabförmigen Distanzelementes 9 angeordnet ist, um als Aufnahme für das Zubehörteil 7 zu dienen. Wie aus der Schnittdarstellung von Figur 10 am besten zu erkennen ist, besitzt es eine Durchgangsbohrung 110, die eng toleriert dem einseitig angefasten Querschnitt des Distanzelementes 9 entspricht. In Richtung der senkrecht zu dieser Durchgangsbohrung 110 verlaufenden Längsachse des Klemmelementes 11 ist von seiner dem Zubehörteil 7 abgewandten Seite her eine erste Gewindebohrung 111 des Klemmelementes 11 zur Aufnahme einer in der Zeichnung nicht dargestellten Befestigungsschraube, beispielsweise einer Madenschraube vorgesehen. Mit dieser Befestigungsschraube ist das Klemmelement 11 an dem Distanzelement 9 kraftschlüssig festzulegen.FIGS. 9 to 11 each show a view of the clamping element 11, which is arranged at the end of the rod-shaped spacer element 9 remote from the lamp, in order to serve as a receptacle for the accessory part 7. As can best be seen from the sectional illustration in FIG. 10, it has a through-bore 110 which, with a close tolerance, corresponds to the cross-section of the spacer element 9 which is chamfered on one side. In the direction of the longitudinal axis of the clamping element 11 running perpendicular to this through-bore 110, a first threaded bore 111 of the clamping element 11 is provided from its side facing away from the accessory part 7 for receiving a fastening screw, not shown in the drawing, for example a grub screw. With this fastening screw, the clamping element 11 is non-positively fixed on the spacer element 9.

In Richtung auf das Zubehörteil 7 weist das Klemmelement 11 einen durch zwei parallel zu seiner Längsachse stehende Schenkel 112 bzw. 113 gebildeten U-förmigen Querschnitt auf. Dabei ist der untere Schenkel 113 beidseitig angefast und dient als Auflagefläche für das randseitig zwischen diese beiden Schenkel 112 bzw. 113 einzuschiebende Zubehörteil 7. Es kann zweckmäßig sein, Anlageflächen 115 für das Zubehörteil 7 an dessen Randform anzupassen, um so auch das Zubehörteil 7 in bezug auf das Klemmelement 11 zu zentrieren. Um das Zubehörteil 7 in der eingeschobenen Lage festzulegen, ist in dem oberen Schenkel 112 parallel zur Achse der Durchgangsbohrung 110 eine weitere Gewindebohrung 114 des Klemmelementes 11 vorgesehen. Auch diese Gewindebohrung dient zur Aufnahme einer Befestigungsschraube, mit der dann das Zubehörteil kraftschlüssig zwischen den beiden Schenkeln 112 bzw. 113 des Klemmelementes 11 festlegbar ist.In the direction of the accessory part 7, the clamping element 11 has a U-shaped cross section formed by two legs 112 and 113 which are parallel to its longitudinal axis. The lower leg 113 is chamfered on both sides and serves as a contact surface for the accessory 7 to be inserted at the edge between these two legs 112 and 113. It may be expedient to adapt contact surfaces 115 for the accessory 7 to its edge shape, in order to also include the accessory 7 in center with respect to the clamping element 11. In order to fix the accessory part 7 in the inserted position, a further threaded bore 114 of the clamping element 11 is provided in the upper leg 112 parallel to the axis of the through bore 110. This threaded hole is also used to hold a fastening screw, with which the accessory part can be non-positively fixed between the two legs 112 or 113 of the clamping element 11.

Figur 2 zeigt in dem vergrößerten Ausschnitt wohl am deutlichsten, wie die beschriebene Einrichtung montiert wird. Das Distanzelement 9 wird von unten in den Schuh 14 der Halterung 10 eingeschoben und ist aufgrund seiner Querschnittsform in einer definierten Lage gegenüber dem Schuh 14 drehbeweglich gesichert. Auf den Schuh 14 wird die Klammer 13 der Halterung 10 so aufgesetzt, daß sein dachförmiger Vorsprung 133 in die V-förmige Nut 145 des Schuhs 14 eingreift. Nach dem Einsetzen der Verbindungsschraube 15 sind die Klammer 13 und der Schuh 14 ebenfalls zueinander zentriert. Die Klammer 13 wird mit ihrem hakenförmigen Ansatz 132 in die Randnut 61 des Abdeckringes 6 eingehängt, anschließend wird die Verbindungsschraube 15 in der endseitigen Gewindebohrung des Distanzelementes 9 angezogen. Aufgrund der mit dem Neigungswinkel α angeschrägten Anlagefläche der Klammer 13 an die Oberseite des Schuhs 14 verspreizt sich die Klammer 13 geringfügig gegenüber dem Schuh 14 derart, daß sich diese beiden Teile der Halterung 10 auch formschlüssig von oben und unten an den Abdeckring 6 kraft- und formschlüssig und vor allem auch toleranzfrei anlegen. Mit dem Festziehen der Verbindungsschraube 15 ist damit die Einrichtung zum Befestigen von Zubehörteilen an der Deckenleuchte 2 bereits eindeutig gegenüber dem Abdeckring 6 und damit der gesamten Deckenleuchte 2 justiert. Nun ist lediglich noch das Klemmelement 11 auf das Distanzelement 9 aufzuschieben, sowie das jeweilige Zubehörteil 7 an dem Klemmelement festzulegen.Figure 2 shows most clearly in the enlarged section how the device described is assembled. The spacer element 9 is inserted from below into the shoe 14 of the holder 10 and, due to its cross-sectional shape, is rotatably secured in a defined position relative to the shoe 14. On the shoe 14, the clip 13 of the bracket 10 is placed so that its roof-shaped projection 133 engages in the V-shaped groove 145 of the shoe 14. After insertion of the connecting screw 15, the bracket 13 and the shoe 14 are also centered on one another. The clip 13 is hooked with its hook-shaped projection 132 into the edge groove 61 of the cover ring 6, then the connecting screw 15 is tightened in the end threaded bore of the spacer element 9. Because of the inclined angle α of the contact surface of the bracket 13 on the top of the shoe 14, the bracket 13 spreads slightly relative to the shoe 14 such that these two parts of the bracket 10 are also positively from above and below on the cover ring 6 form-fitting and above all tolerance-free. By tightening the connecting screw 15, the device for fastening accessories to the ceiling lamp 2 is already clearly adjusted with respect to the cover ring 6 and thus the entire ceiling lamp 2. Now only the clamping element 11 has to be pushed onto the spacer element 9 and the respective accessory part 7 has to be fixed on the clamping element.

Damit ist verdeutlicht, daß die vorstehend beschriebene Einrichtung zum Befestigen von Zubehörteilen an einer Deckenleuchte mit einfachen Werkzeugen auch für einen Laien ohne weiteres montierbar ist und sich dabei zuverlässig und eindeutig gegenüber dem Abdeckring 6 und damit der Deckenleuchte 2 justiert. Dies ist insbesondere dann von Bedeutung, wenn das entsprechende Zubehörteil nicht nur ein äußeres Designmerkmal der Deckenleuchte darstellt sondern auch eine lichttechnische Funktion zu erfüllen hat, bei der es häufig auf eine exakte geometrische Zuordnung des Zubehörteiles gegenüber der an- oder eingebauten Deckenleuchte 2 ankommt.This makes it clear that the device described above for attaching accessories to a ceiling lamp with simple tools can also be easily installed by a layperson and thereby reliably and clearly adjusts itself to the cover ring 6 and thus the ceiling lamp 2. This is particularly important if the corresponding accessory is not just an external design feature represents the ceiling lamp but also has to fulfill a lighting function, in which it is often a question of an exact geometrical assignment of the accessory compared to the attached or installed ceiling lamp 2.

Wie Figur 12 als Darstellung eines weiteren Ausführungsbeispieles zeigt, kann die vorstehend beschriebene Einrichtung gegebenenfalls auch mehrfach vorgesehen sein, um ein Zubehörteil 7 zum Beispiel in einer rotationssymmetrischen Anordnung an der Deckenleuchte 2 bzw. deren Abdeckring 6 festzulegen. Dabei können an sich dieselben Klemmelemente 11 wie bei der vorstehend beschriebenen Ausführungsform verwendet werden. Es ist aber auch denkbar, wie in Figur 12 schematisch dargestellt, ein entsprechendes Zubehörteil 7 nicht randseitig umfassend durch diese Klemmelemente 11 festzulegen. So wäre es denkbar, in einem Zubehörteil nahe dem Umfang Durchgangsbohrungen vorzusehen, in die jeweils ein Befestigungselement eingeschoben wird, das seinerseits an dem Distanzelement 9 mit Hilfe einer Schraubverbindung zu befestigen ist.As shown in FIG. 12 as a representation of a further exemplary embodiment, the device described above can optionally also be provided several times in order to fix an accessory 7, for example in a rotationally symmetrical arrangement on the ceiling lamp 2 or its cover ring 6. In this case, the same clamping elements 11 can be used as in the embodiment described above. However, it is also conceivable, as shown schematically in FIG. 12, not to fix a corresponding accessory part 7 by means of these clamping elements 11. It would be conceivable to provide through holes in an accessory near the circumference, into each of which a fastening element is inserted, which in turn is to be fastened to the spacer element 9 with the aid of a screw connection.
