Ceiling tile unit and a method for forming a ceiling tile unit

Abstract

The present invention relates to a ceiling tile unit comprising a tile body made of mineral fibre material, a surface layer and a guide. The tile body has a front side, a rear side and at least one side edge, and the surface layer is arranged on said front side of said tile body. A groove is provided in said rear side of said tile body dividing said tile body into a first tile body section and a second tile body section. Said guide is adapted to form a fold guidance for inclination of said first tile body section in relation to said second tile body section by folding about an axis parallel to the longitudinal direction of said groove. The invention further relates to a method for forming a ceiling tile unit.

         10 . A ceiling tile unit according to  claim 4 , wherein the profile comprises protrusions forming an angle bar. 
     
     
         11 . A ceiling tile unit according to  claim 1  or  2 , further comprising an additional groove provided in said rear side of said tile body, said groove and said additional groove dividing said tile body into said first tile body section, said second tile body section and a third tile body section, and
 wherein an additional guide is adapted to form a fold guidance for inclination of said third tile body section in relation to said first tile body section by folding about an axis being parallel to said additional groove. 
 
     
     
         12 . A ceiling tile unit according to  claim 1  or  2 , wherein the groove has a square cross section and has a width corresponding to a thickness of the tile body. 
     
     
         13 . A suspended ceiling comprising at least one ceiling tile unit, said at least one ceiling tile unit comprising a tile body made of mineral fibre material, a surface layer and a guide,
 the tile body having a front side, a rear side and at least one side edge,   the surface layer being arranged on said front side of said tile body,   wherein a groove is provided in said rear side of said tile body dividing said tile body into a first tile body section and a second tile body section, and   wherein said guide is adapted to form a fold guidance for inclination of said first tile body section in relation to said second tile body section by folding about an axis parallel to the longitudinal extension of said groove.   
     
     
         14 . A suspended ceiling according to  claim 13 , wherein the guide comprises a crease formed in said surface layer. 
     
     
         15 . A suspended ceiling according to  claim 13  or  14 , wherein the guide comprises a guide body of a compressible material, the guide body being adapted to be arranged in the groove. 
     
     
         16 . A suspended ceiling according to  claim 13  or  14 , wherein the guide comprises a profile insertable in said groove. 
     
     
         17 . A method for forming a ceiling tile unit, comprising
 providing a ceiling tile unit comprising a tile body made of mineral fibre material and a surface layer, said tile body having a front side, a rear side and at least one side edge, and said surface layer being arranged on said front side of said tile body,   forming a groove in said rear side of said tile body dividing said tile body into a first tile body section and a second tile body section,   providing a guide adapted to form a fold guidance for inclination of said first tile body section in relation to said second tile body section by folding about an axis parallel to the longitudinal extension of said groove.
