A planar suspended ceiling system and a method for installing the ceiling system

Abstract

The inventive concept relates to a planar suspended ceiling system comprising: a ceiling tile ( 10 ) having a front side ( 1 ), a rear side ( 2 ) and at least one side edge extending between the front side ( 1 ) and the rear side ( 2 ), the ceiling tile ( 10 ) comprising an acoustical absorbing body ( 4 ), and a front cover ( 3 ) arranged at the front side ( 1 ) of the ceiling tile ( 10 ); wherein a slit ( 5 ) is provided extending across the entire rear side ( 2 ) of the acoustical absorbing body ( 4 ) thereby dividing said acoustical absorbing body ( 4 ) into a first and a second body section ( 4 a, 4 b ), and having a depth such that the ceiling tile ( 10 ) is foldable along the slit ( 5 ) with the front cover ( 3 ) acting as a joint; wherein opposing portions of the at least one side edge are provided with each a groove ( 6 ) and; a grid of profiles ( 11 ) for supporting said ceiling tile ( 10 ) in a planar, non-folded state in which flanges ( 7 ) of the grid of profiles ( 11 ) extend into the grooves ( 6 ) thereby supporting the ceiling tile ( 10 ).

1 . A planar suspended ceiling system comprising:
 a ceiling tile ( 10 ) having a front side ( 1 ), a rear side ( 2 ) and at least one side edge extending between the front side ( 1 ) and the rear side ( 2 ), the ceiling tile ( 10 ) comprising an acoustical absorbing body ( 4 ), and a front cover ( 3 ) arranged at the front side ( 1 ) of the ceiling tile ( 10 ),   wherein a slit ( 5 ) is provided extending across the entire rear side ( 2 ) of the acoustical absorbing body ( 4 ) thereby dividing said acoustical absorbing body ( 4 ) into a first and a second body section ( 4   a ,  4   b ), and having a depth such that the ceiling tile ( 10 ) is foldable along the slit ( 5 ) with the front cover ( 3 ) acting as a joint,   wherein opposing portions of the at least one side edge are provided with each a groove ( 6 ) and,   a grid of profiles ( 11 ) supporting said ceiling tile ( 10 ) in a planar non-folded state in which flanges ( 7 ) of the grid of profiles ( 11 ) extend into the grooves ( 6 ) thereby supporting the ceiling tile ( 10 ).   
     
     
         2 . A system according to  claim 1  wherein the ceiling tile ( 10 ) comprises a compressed fiber material such as glass wool. 
     
     
         3 . A system according to  claim 1  wherein the grid of profiles ( 11 ) have an inverted T-shape. 
     
     
         4 . A system according to  claim 1  wherein the front cover ( 3 ) comprises a woven or nonwoven glass fiber fabric. 
     
     
         5 . A system according to  claim 1  wherein the front cover ( 3 ) is glued to the acoustical absorbing body ( 4 ). 
     
     
         6 . A system according to  claim 1  wherein the grooves ( 6 ) of the ceiling tile ( 10 ) are configured to conceal the grid of profiles ( 11 ) in the planar non-folded state of the ceiling tile ( 10 ), thereby enabling concealed mounting. 
     
     
         7 . A method for installation of a suspended ceiling system comprising:
 a ceiling tile ( 10 ) having a front side ( 1 ), a rear side ( 2 ) and at least one side edge extending between the front side ( 1 ) and the rear side ( 2 ), and a grid of profiles ( 11 ) comprising flanges ( 7 ) for supporting the ceiling tile ( 10 ),   the ceiling tile ( 10 ) comprising an acoustical absorbing body ( 4 ), and a front cover ( 3 ) arranged at the front side ( 1 ) of the ceiling tile ( 10 ),   wherein a slit ( 5 ) is provided extending across the entire rear side ( 2 ) of the acoustical absorbing body ( 4 ) thereby dividing said acoustical body ( 4 ) into a first and a second body section ( 4   a ,  4   b ), and having a depth such that the ceiling tile ( 10 ) is foldable along the slit ( 5 ) with the front cover ( 3 ) acting as a joint,   wherein opposing portions of the at least one side edge are provided with each a groove ( 6 ), the method comprising:   installing the grid of profiles ( 11 ) in a room of a building,   mounting the ceiling tile ( 10 ) in the grid of profiles ( 11 ) by   arranging the ceiling tile ( 10 ) in a folded state by folding the ceiling tile ( 10 ) along the slit ( 5 ) with the front cover ( 3 ) acting as a joint,   directing an apex of the folded ceiling tile ( 10 ) in an upward direction,   advancing the folded ceiling tile ( 10 ) from below to position in which the groves ( 6 ) are aligned with an opposing pair of flanges ( 7 ) of the grid of profiles ( 11 ), and   straightening the folded ceiling tile ( 10 ) to a planar, non-folded state such that the flanges ( 7 ) are received by the grooves ( 6 ).
