Description

Die Erfindung bezieht sich auf eine schalldämpfende Vorrichtung, die an Decken von Räumen beabstandet und parallel zu diesen verlaufend befestigt ist.The invention relates to a sound-damping device which is spaced from and fixed parallel to the ceilings of rooms.

Eine solche Vorrichtung ist aus der DE 10 2012 013266 A1 vorbekannt. Des Weiteren wird auf die DE 10 2015 101480 A1 , CH 708 188 A2 und die WO 2013/035016 A1 verwiesen.Such a device is from DE 10 2012 013266 A1 previously known. Furthermore, on the DE 10 2015 101480 A1 , CH 708 188 A2 and the WO 2013/035016 A1 referred.

Insbesondere in Besprechungszimmern hat sich herausgestellt, dass die durch Schallwellen verursachten Geräuschkulissen das Gespräch zu stören und folglich zu dämpfen sind. Daher werden oftmals Räume mit entsprechend groß bemessenen Abmessungen mithilfe von Flächengebilden, die eine schalldämpfende Eigenschaft aufweisen, entsprechend verkleidet, um die bei Gesprächen entstehenden Schallwellen zu dämpfen bzw. zu absorbieren. Diese Flächengebilde werden in einem Rahmen eingelegt oder eingesetzt und der Rahmen ist beispielsweise mittels Drähten oder Rohrstücken an der Decke befestigt.In conference rooms in particular, it has been found that the background noise caused by sound waves disturbs the conversation and must therefore be dampened. For this reason, rooms with correspondingly large dimensions are often appropriately clad with the aid of fabrics that have a sound-absorbing property, in order to dampen or absorb the sound waves generated during conversations. These fabrics are placed or used in a frame and the frame is attached to the ceiling by means of wires or pieces of pipe, for example.

Die mit schalldämpfenden Eigenschaften ausgerüsteten Flächengebilde haben sich zwar in der Praxis zur Absorbierung von Schallwellen bewährt, jedoch sind oftmals solche Räume ausreichend zu beleuchten, da in diesen Unterlagen anzusehen sind. Die verwendeten Flächengebilde weisen eine rechteckförmige Außenkontur auf, so dass die Rahmen aus einem Verbund von Rahmen besteht die vereinzelt herausgenommen werden können, um in den derart geschaffenen Freiraum eine Deckenlampe einzusetzen, durch die die erforderliche Beleuchtung zur Verfügung gestellt ist.Although the fabrics equipped with sound-absorbing properties have proven themselves in practice for absorbing sound waves, such rooms often have to be adequately illuminated, as can be seen in these documents. The flat structures used have a rectangular outer contour, so that the frame consists of a combination of frames that can be removed individually in order to insert a ceiling lamp into the free space created in this way, through which the required lighting is made available.

Allerdings weisen diese derart geschaffenen Freiräume keinerlei schaltdämpfenden Eigenschaften auf; vielmehr gelangen die Schallwellen ungehindert an die Decke und werden von dieser in das Rauminnere zurückgeworfen. Je mehr solche Freiräume benötigt werden, um die erforderliche Beleuchtung zu schaffen, desto störender sind die von dem Schall verursachten Nebengeräusche, da die Schallwellen in entsprechend groß bemessene Anzahl in das Rauminnere gelangen.However, these free spaces created in this way have no switching-damping properties; Rather, the sound waves reach the ceiling unhindered and are thrown back into the interior of the room. The more such free spaces are required to create the required lighting, the more disturbing are the background noises caused by the sound, since the sound waves reach the interior of the room in a correspondingly large number.

Es ist daher Aufgabe der Erfindung, eine schalldämpfende Vorrichtung der eingangsgenannten Gattung derart weiterzubilden, dass durch diese zum einen die schalldämpfende Eigenschaft möglichst über die gesamte Oberfläche der Decke vorhanden und dass zum anderen eine ausreichende Beleuchtung für das Rauminnere möglich ist.It is therefore the object of the invention to develop a sound-damping device of the aforementioned type in such a way that the sound-damping property is present over the entire surface of the ceiling and that sufficient lighting for the interior of the room is possible.

Diese Aufgabe ist erfindungsgemäß durch die Merkmale des kennzeichnenden Teils von Patentanspruch 1 gelöst.This object is achieved according to the invention by the features of the characterizing part of patent claim 1.

Weitere vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous developments of the invention result from the dependent claims.

Dadurch, dass in dem Flächengebilde mindestens ein Zwischenraum vorgesehen ist, dass in dem jeweiligen Zwischenraum ein oder mehrere Beleuchtungsmittel angeordnet sind und dass jedes der Beleuchtungsmittel unmittelbar oder mittels Abstützelementen an dem Rahmen arretiert ist, soll erreicht sein, dass die durch Gespräche und anderen Geräuschen entstehenden Schallwellen ausreichend absorbiert sind und dass gleichzeitig das Rauminnere mit einer ausreichenden Beleuchtung ausgestattet ist.By providing at least one gap in the fabric, by arranging one or more lamps in the respective gap and by locking each of the lamps to the frame directly or by means of support elements, the aim is to ensure that the noise caused by conversations and other noises Sound waves are sufficiently absorbed and that at the same time the interior of the room is equipped with sufficient lighting.

Da an dem Rahmen eine Abdeckplatte vorgesehen ist, durch die eine Auflage entgegen der Schwerkraftrichtung vorliegt, sind sowohl die Flächengebilde als auch die Beleuchtungsmittel in den jeweiligen Rahmen eingelegt oder eingesetzt, so dass keine zusätzlichen Befestigungselemente erforderlich sind, wodurch die Montage der schalldämpfenden Vorrichtung schnell und kostengünstig herstellbar ist. Durch die Abdeckplatte werden demnach die Flächengebilde und die Beleuchtungsmittel gehalten.Since a cover plate is provided on the frame, through which there is a support against the direction of gravity, both the surface structure and the lighting means are laid or inserted in the respective frame, so that no additional fastening elements are required, which means that the installation of the sound-damping device is quick and easy can be produced inexpensively. Accordingly, the flat structures and the lighting means are held by the cover plate.

Um sowohl die Ausleuchtung als auch die schalldämpfenden Eigenschaften der Flächengebilde zu optimieren, sind in die Abdeckplatte eine Vielzahl von Durchgangsöffnungen und Beleuchtungsdurchtritte eingearbeitet, die entweder dem jeweiligen Flächengebilde oder der jeweiligen LED der Beleuchtungsmittel zugeordnet sind. Somit können die Schallwellen durch die Durchgangsöffnungen in das Flächengebilde, das vorzugsweise als Polyestervlies ausgestaltet ist, nahezu ungehindert in dieses eindringen und dort absorbiert werden und die von den jeweiligen LED erzeugten Lichtwellen treten durch die Beleuchtungsdurchtritte in das Rauminnere, so dass dieser entsprechend ausgeleuchtet ist.In order to optimize both the illumination and the sound-absorbing properties of the surface structure, a large number of through openings and lighting passages are incorporated into the cover plate, which are assigned either to the respective surface structure or to the respective LED of the lighting means. The sound waves can thus penetrate through the passage openings in the fabric, which is preferably designed as a polyester fleece, almost unhindered and be absorbed there, and the light waves generated by the respective LEDs pass through the lighting passages into the interior of the room, so that it is illuminated accordingly.

Die Flächengebilde verhindern somit, dass die Schallwellen von der Decke in das Rauminnere zurückgeworfen oder von dieser reflektiert sind, wodurch erreicht ist, dass störende Geräuschkulissen gedämpft sind. Mithilfe der Beleuchtungsmittel, die vorzugsweise in zwei parallel zueinander verlaufenden Reihen angeordnet sind, wird dabei ein sehr geringer Flächenbedarf im Verhältnis mit der von den Flächengebilde abgedeckten Oberflächen der Decken eingenommen, so dass die schalldämpfenden Eigenschaften der Vorrichtung überwiegen.The fabrics thus prevent the sound waves from being thrown back from the ceiling into the interior of the room or reflected from it, which means that disturbing background noises are dampened. With the aid of the lighting means, which are preferably arranged in two rows running parallel to one another, a very small area is required in relation to the surfaces of the ceilings covered by the fabrics, so that the sound-absorbing properties of the device predominate.

In Figur 1 ist eine übliche Besprechungssituation in einem Raum 2 schematisch dargestellt, in dem an dessen Decke 3 zwei erfindungsgemäße Vorrichtungen 1 aufgehängt sind, durch die beispielsweise durch Gespräche entstehende Schallwellen 6 absorbiert werden sollen, so dass diese von der Decke 3 nicht in das Rauminnere zurückgeworfen bzw. reflektiert sind und gleichzeitig eine ausreichende Beleuchtung des Raumes 2 einstellbar sein soll.In figure 1 a typical meeting situation is shown schematically in a room 2, in which two devices 1 according to the invention are suspended from the ceiling 3, by means of which sound waves 6, for example caused by conversations, are to be absorbed so that they are not thrown back from the ceiling 3 into the interior of the room or are reflected and at the same time sufficient lighting of the room 2 should be adjustable.

Die Vorrichtung 1 besteht dabei aus drei Flächengebilden 5, die in einem Rahmen 4 eingelegt sind, der beabstandet von der Decke 3 und parallel zu dieser auferlegt ist. Dabei kann der Rahmen 4 eine L-förmige Querschnittsstruktur aufweisen, so dass die jeweiligen Flächengebilde 5 an den umlaufenden Rahmen 4 abgestützt sind. Die benachbart zu der erfindungsgemäßen Vorrichtung 1 an der Decke 3 abgehängten Rahmen 4 haben zwar die identische Außenabmessung, bestehen jedoch ausschließlich aus einem einschlägigen Flächengebilde 5, so dass diese ausschließlich zur Schallabsorption eingesetzt sind.The device 1 consists of three fabrics 5, which are inserted in a frame 4, which is spaced apart from the ceiling 3 and imposed parallel to it. The frame 4 can have an L-shaped cross-sectional structure, so that the respective fabrics 5 are supported on the surrounding frame 4 . The frames 4 suspended from the ceiling 3 adjacent to the device 1 according to the invention have the identical external dimensions, but consist exclusively of a relevant surface structure 5, so that they are used exclusively for sound absorption.

Die erfindungsgemäße Vorrichtung 1 weist dagegen zwischen zwei benachbarten Flächengebilden 5 einen Zwischenraum 11 auf, in den Beleuchtungsmittel 12 eingesetzt sind. Die Beleuchtungsmittel 12 bestehen aus einer Vielzahl von LEDs, die paarweise in Reihe zueinander angeordnet sind. Folglich nehmen die Reihen von Beleuchtungsmittel 12 einen wesentlich geringere Fläche ein als die dazu benachbarten Flächengebilde 5, so dass die überwiegende Oberfläche der Vorrichtung 1 schallabsorbierende Eigenschaften aufweist und lediglich eine dazu wesentlich geringere bemessenen Fläche die Beleuchtung für den Raum 2 zur Verfügung stellt.The device 1 according to the invention, on the other hand, has an intermediate space 11 between two adjacent flat structures 5, in which the lighting means 12 are inserted. The lighting means 12 consist of a large number of LEDs which are arranged in pairs in series with one another. Consequently, the rows of lighting means 12 take up a significantly smaller area than the adjacent planar structure 5, so that the majority of the surface of the device 1 has sound-absorbing properties and the lighting for the room 2 is only available on a significantly smaller dimensioned area.

Aus den Figuren 2, 3, 4a und 4b ist ersichtlich, dass in dem Rahmen 4 eine Abdeckplatte 14 eingelegt oder an diesem fixiert ist. In die Abdeckplatte 14 sind eine Vielzahl von Durchgangsöffnungen 15 sowie Beleuchtungsdurchtritte 16 eingearbeitet. Die Durchgangsöffnungen 15 sind dabei benachbart zu den jeweiligen Flächengebilden 5 und die Beleuchtungsdurchtritte 16 fluchtend zu dem jeweiligen Beleuchtungsmittel 12 angeordnet. Folglich können die Schallwellen 6 durch die Durchgangsöffnungen 15 in Richtung des jeweiligen Flächengebilde 5 hindurch gelangen und die von den Beleuchtungsmittel 12 emittierten Lichtwellen werden durch die Beleuchtungsdurchtritte 16 in den Raum 2 geleitet.From the figures 2 , 3 , 4a and 4b it can be seen that a cover plate 14 is inserted in the frame 4 or fixed to it. A large number of passage openings 15 and lighting passages 16 are incorporated into the cover plate 14 . The passage openings 15 are arranged adjacent to the respective surface structures 5 and the lighting passages 16 are arranged in alignment with the respective lighting means 12 . Consequently, the sound waves 6 can pass through the through-openings 15 in the direction of the respective fabric 5 and the light waves emitted from the lighting means 12 are guided into the space 2 through the lighting passages 16 .

Gleichzeitig hält die Abdeckplatte 14 die Flächengebilde 5 und die Beleuchtungsmittel 12 entgegen der Schwerkraft an dem Rahmen 4.At the same time, the cover plate 14 holds the fabric 5 and the lighting means 12 against the force of gravity on the frame 4.

Um störende Lichtreflexionen zu vermeiden, sind zwischen der Abdeckplatte 14 und dem jeweiligen Beleuchtungsmittel 12 ein Rohrstück 17 eingesetzt, so dass die Beleuchtungsmittel 12 geringfügig von der Abdeckplatte 14 beabstandet sind.In order to avoid disturbing light reflections, a piece of pipe 17 is inserted between the cover plate 14 and the respective lighting means 12 so that the lighting means 12 are slightly spaced from the cover plate 14 .

Für den Betrieb der Beleuchtungsmittel 12 sind elektrische Bauteile 7 erforderlich, beispielsweise in Form von Leiterplatten mit elektrischen Leitungen, Transformatoren, Widerständen oder dergleichen. Diese elektrischen Bauteile 7 sind auf der gegenüberliegenden Seite der Abdeckplatte 14, also oberhalb der Beleuchtungsmittel 12, im montierten Zustand angeordnet und werden mittels eines Deckels 18 gekapselt. Der Deckel 18 ist somit der Decke 3 zugewandt und beabstandet von dieser angeordnet.Electrical components 7 are required for the operation of the lighting means 12, for example in the form of printed circuit boards with electrical lines, transformers, resistors or the like. In the mounted state, these electrical components 7 are arranged on the opposite side of the cover plate 14 , ie above the lighting means 12 , and are encapsulated by means of a cover 18 . The cover 18 thus faces the ceiling 3 and is arranged at a distance from it.

Benachbarte Rahmen 4 liegen einer Ebene und zwischen dieser soll kein oder lediglich ein geringer Luftspalt vorhanden sein.Adjacent frames 4 are in one plane and there should be no or only a small air gap between them.
