  • the invention relates to a ceiling absorber element, comprising a frame part, which on one side has a sound-permeable, continuous closed and level aligned sound entrance surface, wherein the rear side of the sound entrance surface foam members are arranged for sound absorption.
  • Absorber elements of the type in question are known. These are used for sound absorption, especially in enclosed spaces and have fastening means for fixing the absorber element to the ceiling.
  • the foam parts are interrupted along two running between opposite frame rails suspension rails to form separate, block-like foam elements.
  • the suspension rails are accordingly preferably part of the ceiling absorber element and are at least partly in a position of concealment within the frame part rear region of the absorber element in the absorber space defined by the foam part.
  • the foam part is interrupted accordingly to form block-like foam elements, further wherein the foam part or the block-like foam elements has a height considered perpendicular to the surface extension of the absorber element, which corresponds to a multiple of measured in the same direction height of the suspension rails.
  • the ceiling absorber element can be arranged close to the ceiling, furthermore possibly without gaps.
  • the block-like foam elements Moreover, further form a one-piece foam part, so that further, a continuous sound entry surface aligned with the frame part is given by the foam part.
  • the suspension rails are hereby preferably in valley-shaped incisions between two block-like, adjacent foam elements.
  • the suspension rails are screw-connected to the frame part, this more preferably with the interposition of the remaining between the block-like foam elements foam section, which on the connection of suspension rails and frame part at the same time the foam part is fixed.
  • the foam part has three foam elements, each with suspended between two adjacent foam elements suspension rails.
  • the foam elements can in this case further considered transversely to the orientation of the suspension rails have the same widths. Alternatively, different widths may be provided in this respect.
  • the outer, ie peripheral foam elements are the same width, while in a preferred embodiment with three foam elements, the middle foam element has a respect to the edge-side foam elements about twice the width.
  • At least two of the foam elements are chamfered along mutually parallel frame sides in such a way that they drop toward the edge which is not overstressed. Accordingly, a skew starting from the frame part in the direction of the installed state of the ceiling facing side is given, which offers both optical advantages at the same time an enlargement of the lateral, over the frame part projecting freely towards the ceiling absorption surface.
  • the height of a foam element which extends rearwardly beyond the frame corresponds to two or more times the frame width, so more preferably approximately 2 to 10 times, more preferably approximately 2 to 4 times the frame width or the frame height measured in the height direction of the foam element.
  • this angle is about 5 ° to 75 ° to a perpendicular to the sound entrance surface. In a preferred embodiment, this angle is about 30 ° to 60 °, more preferably 45 °, this further each inclination of the chamfer to the element interior.
  • the indicated numerical bandwidths also include all intermediate values, if not already indicated by way of example anyway, in particular in 1/10 steps, further in 1/10 steps from the lower and / or upper limit to the respective other limit limited.
  • "And” stands for the fact that both borders are shifted by one or more tenths to the limit, i. can be limited.
  • the foam element consists of an open-cell foam.
  • the foam element may also consist of a melamine resin foam.
  • the proposed absorber element is designed as a broadband absorber.
  • an absorber element according to the invention with a length of 2,500 mm, a width of 1,250 mm and a thickness of 80 mm at a frequency of about 100 Hz has a sound absorption coefficient of about 0.5, in a frequency range of about 91 to about 150 Hz, a sound absorption level of about 0.51 to 1.0, in a frequency range of about 151 to about 600 Hz, and in a frequency range of about 1.601 to 5000 Hz a sound absorption of about 1.01 to 1.5 and in a frequency range from about 601 Hz to about 1,600 Hz, a sound absorption level of about 1.51 to about 1.7.
  • a ceiling absorber element 1 for placement on a ceiling 2 of a room 3.
  • the absorber element 1 shown in the embodiment has a square outline with an edge length of about 1250 mm.
  • the absorber element 1 may also have a rectangular ground plan, so for example. Having a length of 2,500 mm and a width of 1,250 mm.
  • the absorber element 1 is, as further example. From the perspective view in Fig. 7 to recognize, essentially of a frame part 4, a foam part 5 and two suspension rails. 6
  • the frame part 4 is formed from a circumferential support profile, consisting of a metal material, in particular aluminum.
  • the support profile is L-shaped in cross-section, with legs which have approximately equal lengths, so in the illustrated embodiment about 10 mm.
  • the profile forms a support leg 7 oriented horizontally in the installed state and a frame leg 8 aligned perpendicular thereto.
  • the free peripheral edge of the surrounding support leg 7 pointing inwards leaves a window 9.
  • the frame part 4 comprises the foam part 5, which has a plan contour adapted to the inner contour of the frame part 4 or the surrounding frame leg 8. Correspondingly, the foam part 5 rests circumferentially on the support leg 7 of the frame part 4.
  • the foam part 5 consists in the illustrated embodiment of a melamine resin foam and has a perpendicular to the surface of the support leg 7 measured height a, which corresponds to about 3.5 times the height measured in the same direction of the frame leg 8.
  • the foam part 5 is provided with two incisions 10 extending parallel to these frame sides. These are in cross section as shown in FIG Fig. 6 in approximately rectangular shape with respect to the side facing away from the frame part 4 surface of the foam part 5 opening. To the frame part side surface of the foam part 5 through each incision 10 ends at a distance, this correspondingly leaving a continuous foam part bridge section 11. Accordingly, the frame part 4 facing and exposed through the window 9 foam part surface is designed as a closed, level aligned sound entrance surface 12.
  • the foam part 5 is divided into three separate, block-like foam elements 13, 14, which are connected together under integral formation on the bridge sections 11.
  • the arrangement and opening width of the incisions 10 is in this case selected so that the width of the two edge-side foam elements 13 measured transversely to the height extent of the foam part 5 is the same and the corresponding width of the middle foam element 14 corresponds approximately to 2 times an edge-side foam element 13.
  • edge-side foam elements 13 are chamfered along the associated, parallel frame leg 8, this further, starting from a plane spanned by the free edge of the peripheral frame leg 8 level towards the element interior. This concludes the created Chamfer 15 an angle ⁇ of 45 ° to a perpendicular to the sound inlet surface 12 a.
  • the incisions 10 have a free width, which is adapted to the cross-sectional width of the male suspension rails 6.
  • the suspension rails 6 are designed in cross-section approximately C-shaped, with a C-opening facing the incision opening.
  • the rails are made equal to the frame part 4 of a metal material, further example. Of aluminum and extend over the inside width between two leg inner sides of the transverse to the suspension rails 6 aligned, parallel frame legs 8. Accordingly, end portions of the suspension rails 6 in a projection on the Support leg 7 of the frame part 4 in coverage to portions of the frame legs. 8
  • the incisions 10 extend continuously in their longitudinal extension, opening towards the respective edge surfaces of the foam part 5.
  • the suspension rails 6 have a height measured perpendicular to the plane of the sound entrance surface 12, which corresponds to approximately one quarter of the height of the incisions 10 measured in the same direction. Accordingly, the suspension rails 6 positioned in a lowered position in the recesses 10 between the foam elements 13 and 14.
  • the cover-side determination is carried out via fixing elements 17 anchored on the ceiling side. These have a rod-shaped mounting portion 18, to which an end adapted to the free cross section of the suspension rails 6, shoe-like support portion 19 is attached. Suspending the ceiling absorber element 1 is effected by sliding it sideways while inserting the support sections 19 into the suspension rails 6.
