Description

In Fig.1 1 ist schematisch eine bekannte Wandverkleidung 10 dargestellt. Vor der in gestrichelten Linien angedeuteten Gebäudewand 11 sind im Abstand voneinander mehrere zylinderförmige Wandelemente 12-15 aufgestellt. Diese Wandelemente weisen einen horizontalen Querschnitt auf, der einem gleichschenkligen oder einem gleichseitigen Dreieck entspricht. Die Elemente sind jeweils so angeordnet, daß sie um senkrechte Achsen 16-19 drehbar sind. Durch Drehen der Wandelemente 12-15 um diese Achse kann die Fläche, die dem der Wand 11 abgewandten Raum zugewandt ist, verändert werden. Aufgrund des großen Volumens jedes Wandelementes 12-15 ist ein verhältnismäßig großer Abstand zwischen der Gebäudewand 11 und der abschließend von den Elementen gebildeten, dem Raum zugewandten Wand 20 notwendig.A known wall covering 10 is shown schematically in FIG. In front of the building wall 11 indicated in dashed lines, a plurality of cylindrical wall elements 12-15 are placed at a distance from one another. These wall elements have a horizontal cross section, which corresponds to an isosceles or an equilateral triangle. The elements are each arranged so that they are rotatable about vertical axes 16-19. By rotating the wall elements 12-15 about this axis, the area facing the space facing away from the wall 11 can be changed. Due to the large volume of each wall element 12-15, a relatively large distance between the building wall 11 and the wall 20, which is finally formed by the elements and faces the room, is necessary.

In Fig. 2 ist ein anderes bekanntes Ausführungsbeispiel dargestellt, bei dem die einzelnen Wandelemente 21-23 aus kreisförmigen Zylindern, also Rollen, bestehen, die um senkrechte Achsen 24-26 drehbar sind. Zwischen jeweils aneinandergrenzenden Rollen sind in der Fig. 2 senkrecht verlaufende Blenden 27-29 angeordnet. Aufgrund ihres großen Volumens sind derartige Rollen äußerst schwer manipulierbar.Another known embodiment is shown in FIG. 2, in which the individual wall elements 21-23 consist of circular cylinders, that is to say rollers, which can be rotated about vertical axes 24-26. In FIG. 2, diaphragms 27-29 are arranged vertically between adjacent rollers. Due to their large volume, such roles are extremely difficult to manipulate.

Bei der in Fig. 3 gezeigten Ausführungsform einer erfindungsgemäßen Wandverkleidung ist vor der Gebäudewand 30 ein aus senkrechten und waagerechten Streben 31-34 verlaufendes Gittergerüst 35 angeordnet. Das Gittergerüst ist in einem geringen Abstand vor der Gebäudewand 30 angeordnet oder unmittelbar auf diese aufgesetzt Durch die Streben in dem Gittergerüst werden einzelne Felder, beispielsweise 36, 37, 38, 39, abgeteilt. Jedes Feld ist durch einen Rahmen eingerahmt, von denen nur der Rahmen 40 für das Feld 39 im einzelnen dargestellt ist. Bei dem vorliegenden Ausführungsbeispiel ist jeder dieser Rahmen an seiner senkrechten linken Kante in Fig. 3 an dem Gittergerüst 35 mit Hilfe von Scharnieren 41,42 angelenkt. Der Rahmen 40 ist somit um eine senkrechte Achse, die in oder vor der Strebe 32 verläuft, verschwenkbar. Der bzw. die Rahmen können aus Holz, Kunststoff oder Metall bestehen und sie können aus dem gleichen Material oder einem verschiedenen Material wie das Gittergerüst 35 hergestellt sein. Das Gittergerüst kann ggf. auch entfallen, wenn die einzelnen Rahmen unmittelbar an der Gebäudewand angelenkt sind.In the embodiment of a wall cladding according to the invention shown in FIG. 3, a lattice structure 35 extending from vertical and horizontal struts 31-34 is arranged in front of the building wall 30. The lattice structure is arranged at a short distance in front of the building wall 30 or placed directly on top of it. The struts in the lattice structure separate individual fields, for example 36, 37, 38, 39. Each field is framed by a frame, of which only the frame 40 for the field 39 is shown in detail. In the present exemplary embodiment, each of these frames is articulated on its vertical left edge in FIG. 3 to the lattice structure 35 with the aid of hinges 41, 42. The frame 40 can thus be pivoted about a vertical axis which runs in or in front of the strut 32. The frame or frames can consist of wood, plastic or metal and they can be made of the same material or a different material as the lattice structure 35. The lattice structure can also be omitted if the individual frames are hinged directly to the building wall.

In dem Rahmen 40 ist ein Wandelement 43 um eine senkrechte Symmetrieachse A verschwenkbar gehaltert. Die Schwenkachse A verläuft symmetrisch sowohl in Bezug auf den Rahmen 40 wie auch auf eine senkrechte Symmetrieachse des Wandelementes 43. Das Wandelement 43 ist bevorzugt in Form einer Platte ausgebildet. Die Oberflächen des Wandelementes 43 können beliebig ausgestaltet sein und bevorzugt sind die Vor- und die Rückseite des Wandelementes 43 mit verschiedenen Materialien bzw. Stoffen beschichtet, um ein unterschiedliches akustisches Absorptions- bzw. Reflexionsvermögen des Wandelementes zu erzielen. Trotz des unterschiedlichen akustischen Verhaltens könnten die Wandelemente auf ihrer Vor- und Rückseite durch akustisch transparente Oberflächen natürlich auch so ausgestaltet sein, daß sie ein gleichartiges optisches Aussehen aufweisen, sofern eine Wandverkleidung mit gleichen optischen aber variablen akustischen Eigenschaften gewünscht wird.A wall element 43 is held in the frame 40 so as to be pivotable about a vertical axis of symmetry A. The pivot axis A runs symmetrically both with respect to the frame 40 and to a vertical axis of symmetry of the wall element 43. The wall element 43 is preferably designed in the form of a plate. The surfaces of the wall element 43 can be of any design and the front and rear of the wall element 43 are preferably coated with different materials or substances in order to achieve a different acoustic absorption or reflectivity of the wall element. Despite the different acoustic behavior, the wall elements on the front and back could of course also be designed with acoustically transparent surfaces in such a way that they have a similar optical appearance if a wall covering with the same optical but variable acoustic properties is desired.

Das Wandelement 43 weist an seinen gegenüberliegenden Seitenkanten 44, 45 Rastelemente auf, von denen lediglich das Rastelement 46 sichtbar ist. Dieses Rastelement 46 kann mit einer entsprechenden Ausnehmung auf den Innenseiten der senkrechten Rahmenteile 47 bzw. 48 einrasten. Diese Ausnehmungen sind im einzelnen nicht gezeigt. Ebenso kann der Rahmen 40 selbst mit einer entsprechenden Rastvorrichtung des Gittergerüstes 35, und zwar an der Strebe 33, zusammenwirken. Eine solche Rastvorrichtung 49 kann beispielsweise aus einer federvorgespannten Kugel bestehen, die in eine entsprechende komplementäre Ausnehmung einrastet. Selbstverständlich können anstelle der Rastvorrichtungen auch übliche Verriegelungsvorrichtungen wie Riegel usw. vorgesehen werden.The wall element 43 has locking elements on its opposite side edges 44, 45, of which only the locking element 46 is visible. This locking element 46 can snap into place with a corresponding recess on the inner sides of the vertical frame parts 47 and 48. These recesses are not shown in detail. Likewise, the frame 40 itself can cooperate with a corresponding latching device of the lattice structure 35, specifically on the strut 33. Such a latching device 49 can consist, for example, of a spring-preloaded ball which snaps into a corresponding complementary recess. Of course, conventional locking devices such as bolts etc. can also be provided instead of the latching devices.

Die Wandelemente liegen, wenn der Raum auf ein bestimmtes akustisches Absorptions- bzw. Reflexionsverhalten eingestellt ist, vorzugsweise in der Ebene der Wandverkleidung 50. Das heißt, die Wandelemente liegen jeweils in der Ebene ihres zugehörigen Rahmens und der betreffende Rahmen seinerseits liegt in der Ebene des Gittergerüstes 35. Soll nunmehr das akustische Verhalten des Raumes geändert werden, so kann dies auf einfache Weise dadurch erfolgen, daß die einzelnen Rahmen, wobei in der Darstellung der Fig. 3 lediglich der Rahmen 40 näher dargestellt ist, um ihre senkrechte Achse, d.h. um die Scharniere 41, 42 aus der Ebene des Gittergerüstes 35 heraus verschwenkt werden können. Wenn sich der Rahmen 40 in dieser Verschwenkungsstellung befindet, kann seinerseits das Wandelement 43 um seine senkrechte Achse um 180° verschwenkt werden, bis nunmehr die vorherige Rückseite des Wandelementes 43 der Raumseite zugewandt ist. Nach der Verschwenkung um 180° wird das Wandelement 43 wieder in dem Rahmen 40 verriegelt bzw. einrasten gelassen. Sodann wird der Rahmen 40 seinerseits wieder in seine Ursprunsstellung zurückverschwenkt, das heißt so weit verschwenkt, bis er wieder in derselben Ebene wie das Gittergerüst 35 liegt. Dieser Vorgang wird für alle Felder 36-39 durchgeführt. Am Ende ergibt sich eine Wandverkleidung, die nunmehr gegenüber dem Ausgangszustand ein verändertes Raumakustikverhalten zeigt.If the room is set to a certain acoustic absorption or reflection behavior, the wall elements preferably lie in the plane of the wall cladding 50. That is, the wall elements each lie in the plane of their associated frame and the frame in question lies in the plane of the Lattice structure 35. If the acoustic behavior of the room is now to be changed, this can be done in a simple manner by the individual frames, only the frame 40 being shown in more detail in the illustration in FIG. 3, about its vertical axis, ie around the hinges 41, 42 can be pivoted out of the plane of the lattice structure 35. If the frame 40 is in this pivoted position, the wall element 43 can in turn be pivoted through 180 ° about its vertical axis until the previous rear side of the wall element 43 now faces the room side. After pivoting through 180 °, the wall element 43 is locked again in the frame 40 or snapped into place. The frame 40 is then pivoted back into its original position, that is, pivoted until it is again in the same plane as the lattice structure 35. This process is done for all fields 36-39. In the end, there is a wall cladding that now shows a changed room acoustic behavior compared to the initial state.

Die Wandelemente werden, wie oben beschrie- The wall elements are, as described above
