Description

Die Erfindung betrifft einen Dekorationskörper aus plattenförmigen Elementen, insbesondere Beleuchtungskörper aus Glasplatten, von denen jeweils mindestens zwei benachbarte Elemente mit Hilfe einer Befestigungsvorrichtung zusammengehalten werden, wobei die Befestigungsvorrichtung ein plattenförmiges Stützteil, auf dem am Aussenrand ein Ringflansch ausgebildet ist, der eine durchgehend gleiche Höhe aufweist, und der in jeweils eine am Rand der Aussenseite der Elemente ausgebildete Teilringnut eingreift, umfasst.The invention relates to a decorative body made of plate-shaped elements, in particular lighting elements made of glass plates, each of which at least two adjacent elements are held together with the aid of a fastening device, the fastening device being a plate-shaped support part on which an annular flange is formed on the outer edge and has a uniform height throughout , and which engages in a partial annular groove formed on the edge of the outside of the elements.

Dekorationskörper sind beispielsweise flächige Elemente, die zur Verkleidung von Wänden und/ oder Decken verwendet werden. Derartige Dekorationskörper bestehen aus einzelnen Platten, die mit Befestigungsvorrichtungen an der Wand bzw. der Decke, gegebenenfalls unter zusätzlicher Verwendung eines auf die Wand bzw. unter die Decke genagelten Gerüsts, befestigt werden. Bei als Deckenverkleidung verwendeten Dekorationskörpern werden z.B. mehrere matrixförmig angeordnete quadratische Platten durch an den Ecken der Platten befindliche Klemmvorrichtungen zusammengehalten, und der so gebildete Dekorationskörper wird unter der Decke aufgehängt.Decorative elements are, for example, flat elements that are used to clad walls and / or ceilings. Such decorative bodies consist of individual plates which are fastened to the wall or the ceiling with fastening devices, optionally with the additional use of a scaffold nailed to the wall or under the ceiling. For decorative bodies used as ceiling cladding, e.g. several matrix-shaped square plates are held together by clamping devices located at the corners of the plates, and the decorative body thus formed is suspended from the ceiling.

Eine andere Art von Dekorationskörpern sind Beleuchtungskörper, die entweder flächig zur Anbringung unter einer Decke oder an einer Wand ausgebildet sind, oder aber Bestandteil einer Lampe bzw. eines Leuchters sind. Bei solchen Beleuchtungskörpern sind z.B. mehrere quadratische, eine bestimmte Struktur aufweisende Glasplatten an einem Träger befestigt.Another type of decorative body are lighting fixtures, which are either flat for attachment under a ceiling or on a wall, or are part of a lamp or a chandelier. In such lighting fixtures, e.g. several square glass plates with a certain structure attached to a support.

Aus der US-A-2 958 761 ist ein Dekorationskörper bekannt, der kreisförmige Stützteile sowie Stützteile mit Kreissegmenten aufweist. Bei diesen Stützteilen ist es jedoch nicht möglich, die jeweilige Teilringnut in den plattenförmigen Elementen von dem jeweiligen Rand weiter entfernt anzuordnen, um die Gefahr eines Ausbrechens zu vermindern. Vielmehr müssen bei diesen Stützteilen die Teilringnuten jeweils gleich weit entfernt relativ nahe am Rand angeordnet sein. Eine weitere Entfernung der Ringnuten vom Rand führt bei diesen bekannten Stutzteilen zwangsläufig zu einer Vergrösserung der Stützteile und damit zu einer verminderten Lichtausbeute und einem verschlechterten ästhetischen Aussehen.A decorative body is known from US-A-2 958 761, which has circular support parts and support parts with circular segments. With these support parts, however, it is not possible to arrange the respective partial ring groove in the plate-shaped elements further away from the respective edge in order to reduce the risk of break-out. Rather, in these support parts, the partial ring grooves must be arranged equally far apart and relatively close to the edge. Further removal of the annular grooves from the edge inevitably leads to an enlargement of the support parts in these known support parts and thus to a reduced light yield and a deteriorated aesthetic appearance.

Aus der US-A-3 062 298 ist es bekannt, ein mit einem Stützteil zusammenwirkendes Andrückteil vorzusehen. Dieses Stützteil weist jedoch keinen an seinem Aussenrand angeordneten Ringflansch mit einer durchgehend gleichen Höhe auf.From US-A-3 062 298 it is known to provide a pressing part which interacts with a support part. However, this support part does not have an annular flange which is arranged on its outer edge and has the same height throughout.

Es ist daher Aufgabe der vorliegenden Erfindung, einen Dekorationskörper der eingangs genannten Art derart weiterzubilden, dass eine optimale Lichtausbeute bei einer sicheren Montage erreicht wird.It is therefore an object of the present invention to further develop a decorative body of the type mentioned at the outset in such a way that an optimal light yield is achieved with safe installation.

Bei einem Dekorationskörper der obengenannten Art wird diese Aufgabe erfindungsgemäss dadurch gelöst, dass das plattenförmige Stützteil oval ist und eine sich in dessen Längsrichtung erstreckende Hauptachse aufweist, wobei sich diese Hauptachse quer zu der Lücke, die zwischen benachbarten Kanten der Elemente gebildet wird, erstreckt, und dass die Befestigungseinrichtung ein mit dem Stützteil zusammenwirkendes Andrückteil aufweist, so dass die Elemente durch Formschluss zusammengehalten werden.In a decorative body of the type mentioned above, this object is achieved according to the invention in that the plate-shaped support part is oval and has a main axis extending in its longitudinal direction, this main axis extending transversely to the gap which is formed between adjacent edges of the elements, and that the fastening device has a pressing part which interacts with the support part, so that the elements are held together by positive locking.

Wenn bei dem erfindungsgemässen Dekorationskörper die Andrückteile fest angezogen sind, so sitzen die Ringflansche der Stützteile fest in benachbarten Teilnuten verschiedener plattenförmiger Elemente. Aufgrund der Ringflansche ist ein Ausweichen oder Lösen der plattenförmigen Elemente in deren Ebene nicht möglich. Die Elemente werden also durch Formschluss mit den Befestigungsvorrichtungen zusammengehalten.If, in the decorative body according to the invention, the pressing parts are firmly tightened, the ring flanges of the supporting parts are firmly seated in adjacent partial grooves of different plate-shaped elements. Because of the ring flanges, it is not possible to dodge or loosen the plate-shaped elements in their plane. The elements are thus held together with the fastening devices by a form fit.

Die erfindungsgemässe Verbindung zwischen Befestigungsvorrichtung und plattenförmigem Element ist von besonderem Vorteil bei als Glasplatten ausgebildeten Elementen, da trotz eines relativ geringen Anlagedrucks die Glasplatten sicher zwischen Stützteil und Andrückteil gehalten werden können. Da nur ein geringer Bereich des Randes der Glasplatten erfasst wird, bleibt die Hauptfläche der Glasplatten frei, was besonders vorteilhaft bei Beleuchtungskörpern oder dergleichen ist. Die Befestigungsvorrichtung besteht vorzugsweise aus Metall. Die Teilringnuten der Glasplatten lassen sich sehr leicht herstellen, sie können z.B. in die Ränder der Glasplatten eingefräst werden, wobei die Möglichkeit besteht, gleichzeitig in zwei mit ihren Rändern aneinanderliegende Glasplatten mit zwei mit ihren Rändern aneinanderliegende Glasplatten mit einem Fräsvorgang Teilnuten einzufräsen. Die Teilnuten können selbstverständlich auch beim Formen der Glasplatten gebildet werden.The connection according to the invention between the fastening device and the plate-shaped element is particularly advantageous in the case of elements designed as glass plates, since the glass plates can be held securely between the support part and the pressure part, despite a relatively low contact pressure. Since only a small area of the edge of the glass plates is detected, the main surface of the glass plates remains free, which is particularly advantageous in the case of lighting fixtures or the like. The fastening device is preferably made of metal. The partial ring grooves of the glass plates can be produced very easily, e.g. be milled into the edges of the glass plates, it being possible to simultaneously mill partial grooves in two glass plates lying against one another with their edges with two glass plates lying against one another with one edge. The partial grooves can of course also be formed when molding the glass plates.

Durch die besondere Ausgestaltung der erfindungsgemässen Befestigungsvorrichtungen können verschiedene Vorteile erzielt werden: Da das Stützteil oval, also länglich ist, kann zwischen zwei benachbarten, miteinander durch die Befestigungsvorrichtung verbundenen Platten ein beträchtlicher Zwischenraum überbrückt werden. Die Hauptsache des ovalen Stützteils läuft also bei z.B. quadratischen Glasplatten quer zu der Lücke, die zwischen benachbarten Kanten der Platten gebildet wird. Ein besonderer Vorteil ist darin zu sehen, dass beim Festziehen der Befestigungsvorrichtung, also beim Andrücken des Andrückteils gegen die Innenseite der Platten, das Stützteil sich nur geringfügig in den zugehörigen Teilringnuten zu bewegen vermag. Nach einer gewissen Drehung klemmt das Stützteil aufgrund seiner ovalen Ausgestaltung in der Teilringnut fest, so dass das Stützteil unbeweglich ist und hierdurch die Möglichkeit einer einfachen Montage bietet. Beispielsweise kann mit dem Stützteil ein Schraubenbolzen verbunden sein, auf dessen freiem Ende das Andrückteil sitzt. Wird auf den Schraubenbolzen eine Mutter aufgeschraubt, so wird aufgrund der ovalen Gestalt des Stützteils das Festschrauben erheblich vereinfacht, weil sich der Schraubenbolzen und das Stützteil nicht mitdrehen. Grundsätzlich kann der Schraubenbolzen einstückig mit dem Stützteil ausgebildet sein.Various advantages can be achieved by the special design of the fastening devices according to the invention: Since the support part is oval, that is to say elongated, a considerable space can be bridged between two adjacent plates connected to one another by the fastening device. The main thing of the oval support part thus runs, for example with square glass plates, transversely to the gap which is formed between adjacent edges of the plates. A particular advantage can be seen in the fact that when the fastening device is tightened, that is to say when the pressing part is pressed against the inside of the plates, the supporting part can only move slightly in the associated partial ring grooves. After a certain rotation, the support part clamps due to its oval configuration in the partial ring groove, so that the support part is immovable and thus offers the possibility of simple assembly. For example, a screw bolt can be connected to the support part, on the free end of which the pressure part sits. If a nut is screwed onto the screw bolt, tightening is made considerably easier due to the oval shape of the support part, because the screw bolt and the support part do not rotate. Basically, the screws bolt be integrally formed with the support member.

In einer bevorzugten Ausführungsform ist jedoch der Schraubenbolzen im Hinblick auf eine möglichst einfache und kostensparende Herstellung nicht einstückig mit dem Stützteil ausgebildet, sondern das Stützteil wird von einem Schraubenbolzen mit Kopf aufgenommen, und an den Kopf schliesst ein Abschnitt eckigen, vorzugsweise quadratischen Querschnitts des Bolzens an, auf welchem das mit einer Öffnung entsprechenden Querschnitts versehene Stützteil unverdrehbar sitzt. Aufgrund des eckigen Querschnitts der Öffnung und des genannten Abschnitts des Schraubenbolzens wird eine Relativverdrehung zwischen Schraubenbolzen und Stützteil verhindert.In a preferred embodiment, however, the screw bolt is not formed in one piece with the support part in order to make production as simple and cost-saving as possible, but the support part is received by a screw bolt with a head, and a section of an angular, preferably square cross section of the bolt adjoins the head , on which the support part provided with an opening of corresponding cross-section sits non-rotatably. Due to the angular cross section of the opening and the mentioned section of the screw bolt, a relative rotation between the screw bolt and the support part is prevented.

Alternativ kann der Bolzen auf seiner ganzen Länge runden Querschnitt haben und im Stützteil drehbar sein. Dies ist beispielsweise von Vorteil, wenn der Bolzen in andere Tragelemente eingeschraubt werden soll.Alternatively, the bolt can have a round cross-section over its entire length and can be rotated in the support part. This is advantageous, for example, if the bolt is to be screwed into other supporting elements.

Das Andrückteil ist vorzugsweise ein Andrückring, der auf dem Schraubenbolzen sitzt und an einer auf den Schraubenbolzen aufgeschraubten Mutter anliegt. Eine derartig einfach aufgebaute Befestigungsvorrichtung ist relativ billig in der Herstellung und gewährleistet dennoch eine relativ rasche Montage des Dekorationskörpers.The pressing part is preferably a pressing ring which sits on the screw bolt and rests on a nut screwed onto the screw bolt. Such a simply constructed fastening device is relatively cheap to manufacture and still ensures a relatively quick assembly of the decorative body.

Je nach Verwendung des Dekorationskörpers kann es ausreichen, wenn die erfindungsgemässe Befestigungsvorrichtung die plattenförmigen Elemente lediglich zusammenhält. Wird der Dekorationskörper z.B. unter einer Decke aufgehängt, oder wird er - als Beleuchtungskörper - an einem Lampengestell aufgehängt, so lässt sich eine solche Aufhängung in besonders einfacher Weise dadurch erreichen, dass das dem Kopf abgewandte Ende des Schraubenbolzens eine quer zur Bolzenachse verlaufende Bohrung zur Aufnahme eines Aufhängehakens oder dergleichen aufweist.Depending on the use of the decorative body, it may be sufficient if the fastening device according to the invention merely holds the plate-shaped elements together. If the decorative body e.g. Suspended under a ceiling, or if it is suspended on a lamp frame as a lighting fixture, such a suspension can be achieved in a particularly simple manner by the end of the screw bolt facing away from the head having a bore running transversely to the bolt axis for receiving a suspension hook or the like having.

Im folgenden wird eine Ausführungsform der Erfindung anhand der Zeichnung näher erläutert. Es zeigen:

  • Figur 1 eine Seiten-Teilansicht eines als Leuchtenabdeckung ausgebildeten Dekorationskörpers;
  • Figur 2 eine teilweise geschnittene Detailansicht der in Figur 1 mit bezeichneten Einzelheit und
  • Figur 3 eine perspektivische Ansicht eines Stützteils der in Figur 2 dargestellten Befestigungsvorrichtung.
An embodiment of the invention is explained in more detail below with reference to the drawing. Show it:
  • Figure 1 is a partial side view of a decorative body designed as a lamp cover;
  • Figure 2 is a partially sectioned detail view of the detail indicated in Figure 1 and
  • Figure 3 is a perspective view of a support member of the fastener shown in Figure 2.

Figur 1 zeigt einen Ausschnitt eines z.B. als Leuchtenabdeckung ausgebildeten Dekorationskörpers. Der Körper besteht aus mehreren jeweils identisch ausgebildeten Prismen-Glasplatten 3 quadratischen Grundrisses mit einer Kantenlänge von beispielsweise 5 cm. Der Beleuchtungskörper 1 ist mit Hilfe von Haken 2 an einer (nicht dargestellten) Tragvorrichtung aufgehängt.Figure 1 shows a section of e.g. decorative body designed as a lamp cover. The body consists of several identical prismatic glass plates 3 square plan with an edge length of 5 cm, for example. The lighting fixture 1 is suspended from a support device (not shown) with the aid of hooks 2.

Benachbarte Glasplatten 3 werden mit Hilfe von Befestigungsvorrichtungen 4 zusammengehalten, wobei jeweils eine Befestigungsvorrichtung 4 im mittleren Bereich einer Kante einer Glasplatte 3 angeordnet ist. In Figur 1 besitzt der Beleuchtungskörper nur eine einzige Reihe von Glasplatten 3. Es versteht sich aber, dass ein Beleuchtungskörper auch ein ganzes Feld von Glasplatten 3 enhalten kann, wobei dann die Verbindung zwischen jeweils zwei benachbarten Glasplatten 3 stets über eine Befestigungsvorrichtung 4 erfolgt.Adjacent glass plates 3 are held together with the aid of fastening devices 4, one fastening device 4 each being arranged in the central region of an edge of a glass plate 3. In FIG. 1, the lighting fixture has only a single row of glass plates 3. However, it goes without saying that a lighting fixture can also contain an entire array of glass plates 3, the connection between two adjacent glass plates 3 then always taking place via a fastening device 4.

Wie insbesondere Figur 2 zeigt, besteht die Befestigungsvorrichtung 4 im wesentlichen aus einem Stützteil 5 und einem Andruckring 6. Der Andruckring 6 wird über eine Federscheibe 7 von einer Schraube 8, die auf das freie Ende eines Schraubenbolzens 10 aufgeschraubt ist, gegen die Ränder der Innenseiten zweier benachbarter Glasplatten 3 gedrückt, wobei ein Kopf 12 des Schraubenbolzens 9 das Stützteil 5 gegen die Aussenseiten der Glasplatten 3 presst.As shown in Figure 2 in particular, the fastening device 4 consists essentially of a support member 5 and a pressure ring 6. The pressure ring 6 is via a spring washer 7 by a screw 8, which is screwed onto the free end of a bolt 10, against the edges of the inner sides pressed two adjacent glass plates 3, wherein a head 12 of the bolt 9 presses the support member 5 against the outside of the glass plates 3.

Der Schraubenbolzen besitzt in seinem Gewindeabschnitt eine sich quer zu seiner Längsachse erstreckende Öffnung 10, in die ein Haken 2 einhakbar ist. Zwischen dem Kopf 12 und der Bohrung befindet sich ein glatter Abschnitt 11 runden Querschnitts des Schraubenbolzens 9, und zwischen dem Kopf 12 und dem Abschnitt 11 befindet sich ein Abschnitt 13 quadratischen Querschnitts, dessen Aufgabe im Folgenden erläutert wird.In its threaded section, the screw bolt has an opening 10 which extends transversely to its longitudinal axis and into which a hook 2 can be hooked. Between the head 12 and the bore there is a smooth section 11 with a round cross section of the screw bolt 9, and between the head 12 and the section 11 there is a section 13 with a square cross section, the task of which is explained below.

Das Stützteil 5 hat, wie in Figur 3 gezeigt ist, die Form eines ovalen Plättchens 14 mit einem umlaufenden, ovalen Ringflansch 15. Der Ringflansch 15 hat etwa rechteckigen Querschnitt und ist etwas abgerundet, wie aus Figur 2 ersichtlich ist. In seiner Mitte besitzt das Plättchen 14 eine quadratische Öffnung 16, die etwas grösser bemessen ist als der Querschnitt des Abschnitts 13 des Schraubenbolzens 9. Wenn der Schraubenbolzen 9 soweit in das Stützteil 5 eingesetzt ist, dass der Kopf 12 an der Aussenseite des Stützteils anliegt, verhindert der Abschnitt 13 in Verbindung mit der Öffnung 16 eine Relativ-Verdrehung zwischen dem Stützteil 5 und dem Schraubenbolzen 9.As shown in FIG. 3, the support part 5 has the shape of an oval plate 14 with a circumferential, oval ring flange 15. The ring flange 15 has an approximately rectangular cross section and is somewhat rounded, as can be seen from FIG. In the middle, the plate 14 has a square opening 16 which is dimensioned somewhat larger than the cross section of the section 13 of the screw bolt 9. When the screw bolt 9 is inserted into the support part 5 so far that the head 12 lies against the outside of the support part, the section 13 in connection with the opening 16 prevents a relative rotation between the support part 5 and the screw bolt 9.

In den einander gegenüberliegenden Randbereichen der Glasplatten 3 ist jeweils eine etwa halbkreisförmige Teilringnut 17 ausgebildet, in die ein Teil des Ringflansches 15 eingreift. Das Stützteil 5 erstreckt sich mit seiner Hauptachse, also in Längsrichtung, zwischen den beiden Glasplatten 3.In the opposite edge regions of the glass plates 3, an approximately semicircular partial annular groove 17 is formed, in which a part of the annular flange 15 engages. The supporting part 5 extends with its main axis, that is to say in the longitudinal direction, between the two glass plates 3.

Bei der Montage des Beleuchtungskörpers 1 ist die Mutter 8 soweit auf dem Schraubenbolzen 9 zurückgedreht, dass der Abstand zwischen dem Andruckring 6 und dem Stützteil 5 so gross ist, dass der Rand mit der Teilringnut 17 der Glasplatte 3 in Richtung des Schraubenbolzens eingeschoben werden kann, der hochstehende Teil 18, der durch die Ringnut 17 gebildet wird, also gleichsam hinter den betreffenden Teil des Ringflansches 15 einhakt. Wenn beide Glasplatten eingehakt sind, kann die Mutter 8 angezogen werden, wobei die Federscheibe 7 ein geringfügiges Nachgeben des Andruckelements 6 ermöglicht. Beim Anziehen der Mutter 8 kann sich das Stützteil 5 und mithin der Schraubenbolzen 9 nur begrenzt um die Längsachse des Schraubenbolzens 9 bewegen, so dass keine weiteren Werkzeuge bei der Montage erforderlich sind. Auf einen Schlitz in dem Kopf 12 zum etwaigen Gegenhalten beim Anziehen der Mutter 8 kann verzichtet werden, so dass der Kopf 12 ein optisch vorteilhaftes Erscheinungsbild hat.When installing the lighting fixture 1, the nut 8 is turned back on the screw bolt 9 to such an extent that the distance between the pressure ring 6 and the support part 5 is so great that the edge with the partial ring groove 17 of the glass plate 3 can be pushed in in the direction of the screw bolt, the upstanding part 18, which is formed by the annular groove 17, so hooks as it were behind the relevant part of the ring flange 15. If both glass plates are hooked in, the nut 8 can be tightened, the spring washer 7 allowing the pressure element 6 to yield slightly. When tightening the nut 8, the support member 5 and thus the screw 9 can only limited movement around the longitudinal axis of the bolt 9, so that no further tools are required for assembly. There is no need for a slot in the head 12 to counteract when tightening the nut 8, so that the head 12 has an optically advantageous appearance.
