Abstract

The invention relates to an acoustic panel (1) for producing a wall and ceiling lining, comprising a front face (2) and a rear face (3) and recesses (4, 6) which extend from the front face (2) and from the rear face (3) into the acoustic panel. In order to provide an acoustic panel which both prevents the ability to see through from the front face to the absorber and also prevents particles from passing from the absorber through the acoustic panel (1), according to the invention at least one front-face recess and one rear-face recess (6) are arranged so as to be partially offset from one another and comprise a through-opening (7).

First claim

The invention claimed is:

1. An acoustic panel ( 1 ) for producing a wall and ceiling covering, comprising
a front face ( 2 ) and a rear face ( 3 ), and
recesses ( 4 , 6 ) which extend from the front face ( 2 ) and from the rear face ( 3 ) into the acoustic panel ( 1 ),
wherein at least one front-face recess ( 4 ) and one rear-face recess ( 6 ) are arranged so as to be offset from one another in sections and comprise a through-opening ( 7 )
wherein
locking profiles ( 16 ), which correspond to one another and which are lockable to one another without the use of adhesive, are arranged on at least two opposing side edges ( 10 a , 10 b ) and
the front-face recesses ( 4 ) protrude to below a profile plane (P) of the acoustic panel, wherein the profile plane (P), starting from the front face ( 2 ), extends parallel to the front face and rear face ( 2 , 3 ) at the deepest point of the locking profiles ( 16 ).

2. The acoustic panel according to claim 1 , wherein the front-face and the rear-face recess ( 4 , 6 ) overlap one another in the direction perpendicular to the panel plane and the through-opening ( 7 ) is arranged in an overlapping portion of the recesses ( 4 , 6 ).

3. The acoustic panel according to claim 1 , wherein, in the case of two recesses ( 4 , 6 ) forming a through-opening ( 7 ), the front-face recess ( 4 ) protrudes more deeply into the acoustic panel ( 1 ) relative to the rear-face recess ( 6 ).

4. The acoustic panel according to claim 1 , wherein the ratio between the panel thickness and the depth of the front-face recess ( 4 ) and the depth of the rear-face recess ( 6 ) is 10:7:6 to 13:9:5.

5. The acoustic panel according to claim 1 , wherein the front-face recess ( 4 ) has a width ratio of 2.5:3 relative to the rear-face recess ( 6 ).

6. The acoustic panel according to claim 1 , wherein the recesses ( 4 , 6 ) are configured as grooves.

7. The acoustic panel according to claim 1 , wherein the through-opening ( 7 ) extends over the entire length of the front-face recess ( 4 ).

8. The acoustic panel according to claim 1 , wherein each of the recesses ( 4 , 6 ) has a fold ( 13 ) in the region of a recess base ( 12 ).

9. The acoustic panel according to claim 1 , wherein the rear-face recesses ( 4 ) are configured to open toward the rear face ( 3 ).

10. The acoustic panel according to claim 1 , wherein the plane formed by the through-opening ( 7 ) is located in an oblique manner.

11. The acoustic panel according to claim 1 , wherein locking profiles ( 16 ) are, in particular, turn-swivel and/or push button profiles.

12. The acoustic panel according to claim 1 , wherein in the case of two recesses ( 4 , 6 ) forming a through-opening ( 7 ), the spacing of the rear-face recess ( 6 ) from a side edge ( 10 a , 10 b ) with an upper groove cheek ( 14 a ) is smaller relative to the spacing of the front-face recess ( 4 ) from the side edge ( 10 a , 10 b ) with the upper groove cheek ( 14 a ).

13. The acoustic panel according to claim 1 , wherein the front-face recess ( 4 ) in the region up to a depth of 20% is 10% to 50% wider relative to the recess width.

14. A wall and ceiling covering comprising acoustic panels ( 1 ) according to claim 1 , which are fastened to a substructure, wherein a sound-attenuating absorber is arranged adjoining a rear face ( 3 ) of the acoustic panels ( 1 ).
