Definitions
- the invention relates to a supporting structure for a suspended ceiling according to the preamble of the main claim.
- Such a supporting structure is known from DE-U-84 35 293.
- bending tongues are arranged on the end pieces of the carrier webs, which have latching heads which can interact with latching receiving holes provided in the hanging bars.
- latching receiving holes provided in the hanging bars.
- the invention has for its object, starting from the known construction, to provide a supporting structure for a suspended ceiling, with which it is possible to use plate-shaped elements, i.e. System modules to connect to the hanging rods, whereby these plate-shaped elements can be adjusted to different heights.
- plate-shaped elements i.e. System modules to connect to the hanging rods, whereby these plate-shaped elements can be adjusted to different heights.
- the claims 7 to 11 relate to the formation of the actual ceiling.
- the hanging rods are equipped on the outside with dovetail-shaped grooves extending over their height, into which appropriately designed support webs can be inserted. These carrier webs are locked with dovetail pins in the dovetail grooves and in turn now carry the actual ceiling panels. This arrangement enables adjustment at any height, and several panels at different heights can also be carried by one hanging bar.
- the actual hanging bars connect to the support device, for example the original ceiling, via a fastening bracket.
- This mounting bracket can be designed in a certain way and the connection of the hanging bar to the mounting bracket can be carried out with the interposition of a ball joint, wherein the carrier webs can also carry ball joints.
- Additional devices such as lights, loudspeakers or the like, can be connected to the hanging bar above and below the plates.
- the supporting structure defined in the claims is preferably intended for a suspended ceiling, but can also be used for fastening wall elements or the like.
- a hanging bar 2 is shown, which is equipped on its outer circumference with dovetail grooves 7 extending over its height.
- This hanging bar 2 connects to a mounting bracket 3 (Fig. 3), which consists essentially of an internally threaded support plate 16 and there is a connecting plate 17 provided with an external thread.
- the connecting plate 17 can be set in an adjustable manner with the interposition of a fixing plate 18 and a fastening screw 19 on the actual carrying device 1, for example a ceiling recognizable from FIG. 3. Because the connection plate 17 has a relatively large central opening 30, adjustments of the fixing plate 18 are easily possible.
- the dowel 31 used to hold the fastening screw 19 is shown in FIG. 5.
- the suspension rod 2 can be fastened to the support plate 16 by means of a support screw 20 and the suspension rod 2 is now securely carried by the support device 1 by screwing the support plate 16 onto the connection plate 17. This construction enables adjustment in the horizontal plane, which enables the hanging rod 2 to be adjusted precisely.
- Carrier webs 4 are used in the dovetail grooves 7 of the hanging rod 2, which essentially consist of two scissors prongs 9 and 10 which can be pivoted about the joint formed by the screw 21. By actuating an expansion screw 11, these tines 9 and 10 can now be pressed apart and thereby dovetail pins 8 arranged on the free ends of the tines 9 and 10 are locked within the dovetail groove 7.

- Fig. 3 shows how 4 different plates 5 and 6 can be connected to different support webs at different heights. While the ceiling plate 5 in FIG. 3 is shown as a relatively thick plate, for example made of wood, the thinner ceiling plate 6 in FIG. 3 is made of a different material, e.g. B. glass.
- the connection via the fastening means 80 shown in FIG. 1 is not possible, but here a fastening screw 14a is simply inserted into a bore 33a.
- the suit case of the "Minifix connection” is actuated by a pivot lever 32 which is arranged on the edge of the plate and which can therefore be actuated from the outside without great effort without the aid of tools.
- This construction also has the advantage that it is possible to detach individual panels 5 or 6 from the dressing in the case of an overall lower-hung ceiling, without having to remove the entire dressing. A single plate can therefore be removed and replaced or certain work can be carried out behind this plate.
- Fig. 4 it is shown how two ceiling panels 5, 6 connect to a hanging bar 2.
- the plates are usually fixed at all three or all four corners.
- the plates are then rounded at their corners 34 and thereby adapt to the shape of the hanging bar 2.
- the holes 33 used to receive the fastening means 80 lie on a straight line which passes through the imaginary tip or corner of the plate 5, 6 and encloses an angle ⁇ with the side edge in the size of 22.5 °. This enables easy assembly with an octagonal hanging bar 2.
- Fig. 4 which shows a plan view of the arrangement shown in Fig. 3, is intended to clarify that the differently designed in shape and material ceiling panels 5, 6 can be connected to the actual hanging bar 2 and how the dovetail grooves 7 are formed.
- connection of the hanging rod 2 can also be carried out with the interposition of a ball joint 12, so that an alignment of the hanging rod 2 with respect to the vertical is possible.
- fastening means 80 it is also possible for the fastening means 80 to be connected to the carrier web 4 with the interposition of a ball joint 50.
- carrier webs 4 are not only ceiling panels 5 and 6 wear, but that it is also possible to connect 4 lighting fixtures 25, loudspeakers or the like to these carrier webs.

Die Erfindung bezieht sich auf eine Tragkonstruktion für eine abgehängte Decke gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a supporting structure for a suspended ceiling according to the preamble of the main claim.
Eine derartige Tragkonstruktion ist durch das DE-U- 84 35 293 bekannt. Bei dieser Anordnung sind an den Endstücken der Trägerstege Biegezungen angeordnet, die Rastköpfe aufweisen, die mit in den Hängestangen vorgesehenen Rastaufnahmelöcher zusammenwirken können. Hierdurch werden die Trägerstege in der Höhe festgelegt, aber können nicht stufenlos in der Höhe eingestellt werden.Such a supporting structure is known from DE-U-84 35 293. In this arrangement, bending tongues are arranged on the end pieces of the carrier webs, which have latching heads which can interact with latching receiving holes provided in the hanging bars. As a result, the height of the support webs is fixed, but they cannot be continuously adjusted in height.
Der Erfindung liegt die Aufgabe zugrunde, ausgehend von der bekannten Konstruktion, eine Tragkonstruktion für eine abgehängte Decke zu schaffen, mit der es möglich ist, plattenförmige Elemente, d.h. Systemmodule, an die Hängestangen anzuschließen, wobei diese plattenförmigen Elemente in unterschiedlichen Höhen einstellbar sind.The invention has for its object, starting from the known construction, to provide a supporting structure for a suspended ceiling, with which it is possible to use plate-shaped elements, i.e. System modules to connect to the hanging rods, whereby these plate-shaped elements can be adjusted to different heights.
Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object underlying the invention will solved by the teaching of the main claim.
Vorteilhafte Ausgestaltungen sind in den Unteransprüchen 2-6 erläutert.Advantageous embodiments are explained in subclaims 2-6.
Die Ansprüche 7 bis 11 beziehen sich auf die Ausbildung der eigentlichen Decke.The
Die Hängestangen sind an ihrer Außenseite mit über ihre Höhe verlaufenden schwalbenschwanzförmigen Aufnahmenuten ausgerüstet sind, in die entsprechend ausgebildete Trägerstege einsetzbar sind. Diese Trägerstege werden mit Schwalbenschwanzzapfen in den Schwalbenschwanznuten arretiert und tragen ihrerseits nunmehr die eigentlichen Deckenplatten. Durch diese Anordnung ist ein Einstellen in beliebiger Höhe möglich, wobei von einer Hängestange auch mehrere Platten in unterschiedlichen Höhen getragen werden können. Die eigentlichen Hängestangen schließen über eine Befestigungskonsole an der Tragvorrichtung, beispielsweise der ursprünglichen Decke, an. Diese Befestigungskonsole kann in bestimmter Weise ausgebildet sein und der Anschluß der Hängestange an die Befestigungskonsole kann unter Zwischenschaltung eines Kugelgelenkes erfolgen, wobei auch die Trägerstege Kugelgelenke tragen können.The hanging rods are equipped on the outside with dovetail-shaped grooves extending over their height, into which appropriately designed support webs can be inserted. These carrier webs are locked with dovetail pins in the dovetail grooves and in turn now carry the actual ceiling panels. This arrangement enables adjustment at any height, and several panels at different heights can also be carried by one hanging bar. The actual hanging bars connect to the support device, for example the original ceiling, via a fastening bracket. This mounting bracket can be designed in a certain way and the connection of the hanging bar to the mounting bracket can be carried out with the interposition of a ball joint, wherein the carrier webs can also carry ball joints.
Oberhalb und unterhalb der Platten können an die Hängestange Zusatzeinrichtungen, wie beispielsweise Leuchten, Lautsprecher od. dgl., angeschlossen werden.Additional devices, such as lights, loudspeakers or the like, can be connected to the hanging bar above and below the plates.
Die in den Ansprüchen definierte Tragkonstruktion ist vorzugsweise für eine abgehängte Decke bestimmt, kann aber auch zur Befestigung von Wandelementen od. dgl. dienen.The supporting structure defined in the claims is preferably intended for a suspended ceiling, but can also be used for fastening wall elements or the like.

In Fig. 1 ist eine Hängestange 2 dargestellt, die auf ihrem Außenumfang mit über ihre Höhe verlaufenden schwalbenschwanzförmigen Nuten 7 ausgerüstet ist. Diese Hängestange 2 schließt an eine Befestigungskonsole 3 (Fig. 3) an, die im wesentlichen aus einer mit Innengewinde versehenen Tragplatte 16 und einer mit Außengewinde versehenen Anschlußplatte 17 besteht. Die Anschlußplatte 17 kann unter Zwischenschaltung einer Festlegplatte 18 und einer Befestigungsschraube 19 an der eigentlichen Tragvorrichtung 1 beispielsweise einer aus Fig. 3 erkennbaren Decke einstellbar festgelegt werden. Dadurch, daß die Anschlußplatte 17 eine relativ große Mittelöffnung 30 aufweist, sind Verstellungen der Festlegplatte 18 leicht möglich. Der zur Aufnahme der Befestigungsschraube 19 dienende Dübel 31 ist in Fig. 5 dargestellt. Über eine Tragschraube 20 kann die Hängestange 2 an der Tragplatte 16 befestigt werden und durch Einschrauben der Tragplatte 16 an der Anschlußplatte 17 wird nunmehr die Hängestange 2 sicher von der Tragvorrichtung 1 getragen. Durch diese Konstruktion wird eine Einstellung in der horizontalen Ebene möglich, was eine exakte Einstellung der Hängestange 2 ermöglicht.In Fig. 1, a
In die Schwalbenschwanznuten 7 der Hängestange 2 werden Trägerstege 4 eingesetzt, die im wesentlichen aus zwei Scherenzinken 9 und 10 bestehen, die um das durch die Schraube 21 gebildete Gelenk scbwenkbar sind. Durch Betätigen einer Spreizschraube 11 können diese Zinken 9 und 10 nun auseinandergepreßt werden und dadurch werden an den freien Enden der Zinken 9 und 10 angeordnete Schwalbenschwanzzapfen 8 innerhalb der Schwalbenschwanznut 7 verriegelt.
An die Unterseite der Trägerstege 4 schließen Befestigungsmittel 80 für Deckenplatten 5 an, wobei bei dem in Fig. 1 dargestellten Ausführungsbeispiel diese Befestigungsmittel 80 aus einer Befestigungsschraube 14 bestehen, mit denen sich das Befestigungsmittel 80 in die Unterseite des Trägersteges 4 einschraubt und aus einem Verbindungsbolzen 15, der in eine Aufnahmebohrung 33 in der Platte eingesetzt werden kann und der mit einem in der Deckenplatte 5 angeordneten Anzugsgehäuse zusammenwirkt. Diese Verbindung ist als"Minifix-Verbindung"® im Stand der Technik allgemein bekannt.Fastening means 80 for
Fig. 3 zeigt, wie in unterschiedlicher Höhe an unterschiedliche Trägerstege 4 unterschiedliche Platten 5 und 6 angeschlossen werden können. Während die Deckenplatte 5 in Fig. 3 als relativ dicke, beispielsweise aus Holz bestehende Platte dargestellt ist, besteht die dünnere Deckenplatte 6 in Fig. 3 aus anderem Werkstoff, z. B. Glas. Hier ist der Anschluß über das in Fig. 1 dargestellte Befestigungsmittel 80 nicht möglich, sondern hier wird einfach eine Befestigungsschraube 14a in eine Bohrung 33a eingesetzt.Fig. 3 shows how 4
Wie aus der Darstellung in Fig. 1 ersichtlich ist, erfolgt die Betätigung des Anzugsgehäuses der "Minifix-Verbindung" durch einen Schwenkhebel 32, der am Plattenrand angeordnet ist und der daher ohne große Mühe von außen ohne Zuhilfenahme von Werkzeug betätigt werden kann. Diese Konstruktionsweise hat weiterhin den Vorteil, daß es möglich ist, bei einer insgesamt tiefergehängten Decke einzelne Platten 5 oder 6 aus dem Verband herauszulösen, ohne daß ein Aufheben des Gesamtverbandes notwendig ist. Es kann also eine einzelne Platte herausgenommen werden und ersetzt werden oder es können hinter dieser Platte bestimmte Arbeiten vorgenommen werden.As can be seen from the illustration in Fig. 1, the suit case of the "Minifix connection" is actuated by a
In Fig. 4 ist gezeigt, wie zwei Deckenplatten 5, 6 an eine Hängestange 2 anschließen. Hier ist darauf hinzuweisen, daß - wie dies insbesondere deutlich die Fig. 8 zeigt - die Platten üblicherweise an allen drei oder allen vier Ecken festgelegt sind. Hierzu sind dann die Platten an ihren Ecken 34 abgerundet und passen sich dadurch der Form der Hängestange 2 an.In Fig. 4 it is shown how two
Die zur Aufnahme der Befestigungsmittel 80 dienenden Bohrungen 33 liegen auf einer Geraden, die durch die gedachte Spitze oder Ecke der Platte 5, 6 geht und einen Winkel α zur Seitenkante in der Größe von 22,5° einschließt. Hierdurch ist bei einer achteckigen Hängestange 2 eine leichte Montage möglich.The
Fig. 4, die eine Draufsicht auf die in Fig. 3 dargestellte Anordnung zeigt, soll verdeutlichen, daß die unterschiedlich in ihrer Form und ihrem Material ausgebildeten Deckenplatten 5, 6 an die eigentliche Hängestange 2 angeschlossen werden können und wie die Schwalbenschwanznuten 7 ausgebildet sind.Fig. 4, which shows a plan view of the arrangement shown in Fig. 3, is intended to clarify that the differently designed in shape and
Aus der Darstellung in Fig. 2 ist erkennbar, daß der Anschluß der Hängestange 2 auch unter Zwischenschaltung eines Kugelgelenkes 12 erfolgen kann, so daß ein Ausrichten der Hängestange 2 gegenüber der Vertikalen möglich ist.From the illustration in Fig. 2 it can be seen that the connection of the hanging
In gleicher Weise ist es möglich, so wie dies in Fig. 7 dargestellt ist, daß auch der Anschluß der Befestigungsmittel 80 an dem Trägersteg 4 unter Zwischenschaltung eines Kugelgelenkes 50 erfolgen kann.In the same way, as is shown in FIG. 7, it is also possible for the fastening means 80 to be connected to the
Bei der Darstellung in Fig. 6 ist verdeutlicht, daß die Trägerstege 4 nicht nur Deckenplatten 5 und 6 tragen, sondern daß es auch möglich ist, an diese Trägerstege 4 Beleuchtungskörper 25, Lautsprecher od. dgl. anzuschließen.6 shows that the
