Abstract

The space planning element (1) has a sound absorbing element (2) provided on a frame (4), and/or a wall and/or ceiling. The sound absorbing element is formed of wavy formation (6) that is arc or curve shaped such that the wavy formation forms the maximum thickness portion of the sound absorbing element. The sound absorbing element is formed parallel to the long side of the frame. A separator (7) made of glass is formed in the space planning element free end.

Description

The invention relates to a space dividing element according to the preamble of claim 1.

The spatial classification elements in question are used for sound insulation or sound absorption in rooms such as open-plan offices, conference rooms, meeting rooms, etc. The sound is perceived in closed rooms in addition to the direct sound also by its reflection from walls, ceilings or other objects. If this is the case, this leads to unpleasant reverberation effects that hinder clear comprehension and concentrated work in this environment, especially in open-plan offices. In particular, the perception of disturbance to human speech and especially in the frequency range of 200-500 Hz is pronounced.

To make matters worse, that in many rooms, especially in new buildings largely soundproof construction materials such as wood, glass and concrete surfaces are used, which further affect the room acoustics due to their strong reverberation and thus contribute to increased Störvorfind.

It is known that the acoustic properties of rooms by usually plate or web-shaped sound absorbers such as in DE 10 2007 000 568 A1 to improve. The sound absorbers typically consist of porous materials such as fibrous materials or plastic foams.

The DE 10 2005 045 702 A1 discloses an absorption module for a particularly vertically oriented installation as a sound absorption device in a room. The absorption module comprises surface elements which are arranged parallel to one another and delimit an absorption space which is filled with an absorption material.

A disadvantage of the known sound absorbers is first of all the fact that an acoustically effective sound insulation or sound absorption in rooms such as open-plan offices can only be implemented with structurally complex means, in particular in the form of a ceiling-high installation. Frequently, such a measure is also associated with a visual obstruction and additional darkening of the rooms.

A disadvantage of freestanding space division elements for sound absorption such. B. Room dividers is the fact that these are not satisfactory because of their substantially open structure of the sound insulation or sound absorption. Since such room dividers are usually not designed to be ceiling high, also resulting in the edges or edges of such space dividing elements adverse Umbeugungseffekte. The acoustically effective design of space division elements as a sound absorber with a low technological cost and taking into account the design and acoustic requirements is thus a challenge.

Unless otherwise stated below, the abovementioned features may be combined as desired individually or in any combination with the subject matter of the invention described below.

It is an object of the invention to improve a space dividing element for sound insulation or sound absorption.

The object is achieved by a space dividing element according to claim 1. Advantageous embodiments and further developments emerge from the subclaims.

Essential is the consideration to form the space dividing element with a wavy shape, which is particularly aligned vertically. The wave-shaped formation means a wavy configuration of the wall thickness of the sound absorber part, as seen in the cross section of the sound absorber part. This wave-shaped formation preferably extends vertically over the entire height of the sound absorber part. If the wave-shaped formation extends over the height, then this is aligned vertically. When viewed in front of the space-dividing element perpendicular to the floor, the wave-shaped formation then protrudes over the entire height of the sound absorber part. The wave-shaped formation then protrudes even when using the space dividing element to the sound incident side, so as to achieve an improved sound insulation or sound absorption in this area, in particular with respect to sound waves occurring laterally on the space dividing element. On the rear side, the sound absorber part is preferably connected to a frame element which, in particular, is free-standing, for example, as a stand construction.

The sound absorber part basically comprises a sound absorber, which preferably consists of a porous material such as glass, mineral wool and / or foams, in particular open-cell foam. The properties such as density, porosity and / or flow resistance are particularly advantageously chosen so that a substantially broadband sound absorption is achieved, in particular in the frequency range of 200 to 500 Hz which is critical for human perceptions.

The wavy shape of the Schallabsorberteils leads to an improved acoustic shielding of the space dividing element. If a sound wave falls on the undulating shape of the sound absorber part, the energy of the sound wave is absorbed more strongly in this area. This enables improved sound insulation or sound absorption in the area of the wave-shaped formation of the sound absorber part. Compared to the planning elements of the state of the art spatial arrangement elements, an improved sound insulation or sound absorption is thus brought about to the screened side of the space segmentation element. Furthermore, possible Umbeugungseffekte be avoided at the edges and edges of the Raumgliederungselementes improved in this way, so that in an optically pleasing manner improved sound absorption or sound absorption of the proposed partitioning element is achieved.

A wavy shape in the sense of the invention means an arcuate, sinusoidal or curved configuration. The cross-section or the wall thickness of the sound absorber part thus increases in this area, so that an increased sound insulation or sound absorption is made possible there. Preferably, the maximum wall thickness of the sound absorber part is in the region of the wave-shaped formation.

In one embodiment of the invention, the wave-shaped formation is arranged adjacent to the lateral edge of the sound absorbing part and / or adjacent to the free end of the space-dividing element. Preferably, the wave-shaped formation of the sound absorber part is designed such that the maximum wall thickness of the sound absorber part is arranged over the width of the Schallabsorberteils seen off-center, in particular towards the free end of the space dividing element. This contributes to the fact that the shielding effect is reinforced towards the free end of the space-dividing element. Furthermore, Umbeugungseffekte be avoided at the lateral edges of the space dividing element to a greater extent. In this way, it is ensured that the areas of a room which are subdivided by a space-dividing element are acoustically effectively shielded.

In a further embodiment, the sound absorber part is flat apart from the wave-shaped formation. In principle, the planar region of the sound absorber part may be formed parallel to the longitudinal side of the frame element and have a constant wall thickness. This not only allows a visually appealing design of the space-dividing element, but also promotes a sound reflection due to the transition from a flat surface to a curved surface of the wave-shaped formation in the sound absorber part.

In one embodiment, the sound absorber part comprises, at least in regions, a protective cover for the sound absorber part which is provided with a multiplicity of apertures. The protective cover preferably covers at least the non-contact with the frame member areas of Schallabsorberteils for example by means of a correspondingly shaped perforated plate o. The like. The protective cover is preferably plate-shaped and may have a wall thickness of 1 to 3 mm. Basically, the protective cover made of metal, plastic, wood or textile can be performed. The openings are preferably formed as holes and / or slots, which are distributed in particular uniformly and / or grid-shaped over the protective cover. This allows mechanical protection of the sound absorber part and at the same time sufficient sound transmission, so that the sound waves can continue to penetrate into the sound absorber part. Particularly advantageously, the protective cover can be realized as a perforated plate, wherein the perforated plate is in particular designed so that the porous sound absorbing material is at least partially enveloped.

In a preferred embodiment, the sound absorber part has fastening means for releasable attachment to the frame element. The fastening means is in particular designed and dimensioned such that a hooking attachment to the frame element is made possible. Accordingly, the attachment means may be provided at opposite ends of the sound absorbing member. This makes it possible to flexibly, so also rotated by 180 ° to mount the sound absorber on the frame member. Depending on the application, the space-dividing element can therefore be flexibly adapted to the conditions in order to achieve acoustically effective sound insulation or sound absorption with targeted shielding.

In a further preferred embodiment, the space-dividing element comprises at least one further separating element. The separating element is preferably made of glass and thus contributes to the fact that the visual obstruction due to the space-dividing element is reduced and at the same time there is sufficient light transmission. Particularly advantageous is the structure of the space dividing element is made so that at the free ends of the Raumgliederungselementes sound absorber parts are provided with wave-shaped formations, which are optionally centrally connected via a separator, for example made of glass. This structure ensures that the shielding effect of the spatial classification element Both free ends of the space dividing element is achieved.

In order to allow soundproofing or sound absorption on both sides of the space-dividing element, sound absorber parts are provided in a preferred embodiment on both longitudinal sides of the frame element. The frame element then has front and rear side a sound absorber part, so that the space dividing element achieves sound insulation or sound absorption on both sides.

In order to enable a structurally simple fastening of the sound absorber part to the frame element, the frame element has in one embodiment connecting elements, in particular in the form of construction profiles for connection to sound absorber parts. The sound absorber part is then in particular designed so that vertically aligned webs are provided with recesses, which allow a positive connection, in particular with the construction profiles of the frame members. The design of the construction profiles is in particular made such that a suspension attachment of the sound absorber parts is made possible. This allows a flexible and easy attachment of Schallabsorberteile to the frame members, which can be done rotated by 90 ° if necessary.

In a particularly preferred embodiment, the frame element is designed as a stand construction, which includes, for example, a foot construction. This makes it possible to set up the space dividing element at any desired location without assembly-technical effort.

It is particularly advantageous to carry out the wave-shaped formation with a maximum wall thickness of the sound absorber part of at least 60 mm, more preferably at least 80 mm. The width of the sound absorber part is preferably at least 500 mm, more preferably at least 700 mm.

The claimed sound absorber part does not necessarily have to be coupled to a frame element. The claimed sound absorber part can be coupled to a wall and / or ceiling of the space-dividing element, preferably by hanging. Such a wall and / or ceiling consist for example of glass or metal. The space dividing element then preferably has no frame elements or a stand construction, in order to minimize the number of parts and thus, above all, to improve the mobility of the system.

In one embodiment, the space-dividing element not only has one or more claimed sound-absorbing parts to lateral boundaries. In this embodiment, one or more further sound-absorbing parts are provided on the wall and / or the ceiling, which are coupled to the space-dividing element, for example, by hanging. The one or more further sound absorber parts have in particular a conventonal shape.

If the claimed room dividing element has a sound absorber part according to the claim under a ceiling, then lateral sound incidence is better dampened compared to flat systems.

A wall of the space dividing element may be straight or curved. For example, the wall may be semicircular.

The info with the impedance jump could, as with the telephone box also appear here.

In particular, the sound absorber part comprises a plurality of porous layers or regions. No air gaps remain between the porous layers or areas. The transition from a porous layer to an adjacent porous layer proceeds with an impedance discontinuity according to the German patent application 10 2007 000 568 A1 associated. This means that the input impedance or the input resistance of a porous region differs so significantly from the input impedance of an adjacent porous region that low frequencies are absorbed below 600 Hz, preferably below 500 Hz. In particular, sound with a frequency of less than 600 Hz is absorbed to at least 50%, preferably to at least 80%. In the following the invention will be explained in more detail by means of exemplary embodiments. In the drawings show:

1 a plan view of a proposed spatial arrangement element,

2 a view of a Schallabsorberteils and

3 a side view of the sound absorber part.

The representation in 1 it can be seen that the proposed spatial arrangement element 1 at least one sound absorbing part 2 and at least one frame member 4 includes. In case of 1 are on both sides of the frame element 4 , So on both sides of the frame element 4 , Sound absorber parts 2 arranged. The sound absorber parts 2 have a wavy shape 6 on that across the width of the Sound absorber part 2 seen off-center, and that are arranged adjacent to the edge of the Schallabsorberteils. On the left side of the in 1 shown room division element 1 are the two-sided on the frame element 4 provided sound absorber parts 2 aligned so that the wavy formations 6 the Schallabsorberteile adjacent to the free end of the Raumgliederungselementes 1 are aligned. It is also possible, as on the right side of 1 visible, the sound absorber parts 2 so on the frame element 4 align that wavy shape 6 spaced from the free end of the space-dividing element 1 are arranged. This arrangement is at the upper Schallabsorberteil 2 on the right side of 1 clarified. For fastening the sound absorber parts 2 on the frame element 4 are connecting means and that profiles 5 at opposite ends of the frame member 4 intended. The profiles 5 serve as below to explain the attachment of Schallabsorberteile 2 ,

Furthermore, the space-dividing element can be a further separating element 7 For example, glass o. The like. To reduce the visual obstruction of a longitudinally extending Raumgliederungselementes while allowing an acoustically effective separation of spatial areas. The separating element 7 is preferred with the frame element 4 connectable designed and can, for example, in the profiles 5 be taken fixed or detachable. In case of 1 is the separator 7 between two frame elements 4 along the longitudinal extent of the frame elements 4 arranged.

2 illustrates in a schematic plan the sound absorber part 2 , The wavy shape 6 preferably in the cross section of the sound absorber part 2 seen a maximum wall thickness 8th of at least 60 mm, more preferably 80 mm. This makes it possible to achieve an effective acoustic sound insulation or sound absorption, in particular with respect to laterally arriving sound waves. Due to the undulating shape on the sound absorber part 2 These sound waves can be better insulated or absorbed. The sound absorber part 2 is, by the way, so apart from the wavy shape 6 , preferably formed flat. The wall thickness in the planar region of the sound absorber part 2 is preferably between 30 and 50 mm, for example 42 mm. As from the illustration in 2 can be seen, the sound absorber part comprises a protective cover for the particular porous sound absorber material of the sound absorber part 2 , Preferably, the protective cover is a perforated plate 3 executed with a plurality of evenly distributed openings, for example in the form of holes. As material for the perforated plate 3 Preferably, metal is used. The shape of the perforated plate 3 Preferably, by rolling, in order to advantageously produce the wavy shape 6 to build.

It is also possible to make the protective cover made of plastic, wood or textile. The breakthroughs for the protective element can also be provided as slots, in order to achieve a targeted sound transmission of the protective element.

The sound absorber part 2 has at the back, so on the side facing away from the sound, basically fastening means 8th on to connect to the frame element 4 to enable. How out 3 can be seen, the fastener 8th as a vertically aligned fastening bar 8a be executed. The fastening bridge 8a In particular, it can also advantageously be made in one piece on the protective cover of the sound absorber part 2 for example, on the perforated plate 3 be formed. The fastening bridge 8a preferably has at least one recess 15 on to a hanging attachment to the frame element 4 to enable. Accordingly, the frame element 4 Connecting elements in the form of profiles 5 have, in particular, are designed as construction profiles and, for example, have U-shaped or a hat-like profiles to a quick hang-attach the Schallabsorberteile 2 to the frame element 4 to enable. The fasteners 8th on the sound absorber part 2 and the corresponding profiles 5 on the frame element 4 are in particular designed such that the sound absorber part is rotated by 180 ° mountable. For this purpose, the recess 15 at the attachment bridge 8a projections 13 have, which are in particular hook-shaped. The projections 13 at a recess 15 are preferably vertically seen at the top and bottom of the recess 15 provided in a structurally advantageous manner by 180 ° twisted mounting of Schallabsorberteils 2 on the frame element 4 to enable. In this way, the undulating shape 6 - as in 1 visible - depending on the application adjacent to the free end of the space dividing element 1 or be aligned remotely to the free end to obtain a targeted acoustic shielding effect of the space dividing element.

The fasteners 8th may be at opposite ends of the sound absorbing part 2 be provided. The width 10 of the fastening bridge 8a , which are - as in 3 visible - perpendicular to the sound absorber part 2 extends, is preferably at least 10 mm, for example 19 mm.

The width 12 of the sound absorber part 2 is preferably at least 500 mm, more preferred at least 700 mm. The height 14 of the sound absorbing part is preferably at least 1500 mm, more preferably at least 1800 mm. These dimensions of the sound absorber part 2 put in connection with the wavy shape 6 a particularly acoustically effective shielding by means of the space-dividing element 1 for sure.

It is particularly advantageous, the sound absorber part 2 as a hanging cassette to an overall stable construction of Schallabsorberteils 2 to obtain. Such a hanging cassette can then be flexible in a particularly simple manner with a frame element 4 connect and, depending on the circumstances of a room together with the wave-shaped formation on Schallabsorberteil 2 Align as required to optimize the room acoustics in the desired manner. Sound absorber parts 2 in the form of hanging cassettes, frame elements 4 and optionally separating elements 7 In particular of transparent material can be combined in a variety of ways to a spatial classification element for sound insulation or sound absorption.
