Mixed suspended ceiling comprising a stretched canvas

Abstract

A suspended ceiling includes at least one canvas ( 4 ) which is tightened at the periphery thereof to support elements ( 1 ) that are fixed to the ceiling and/or walls of a room. The inventive suspended ceiling is characterized by the fact that it also includes ceiling tiles ( 5 ) which are held by the support elements with the aid of holding members that allow the tiles ( 5 ) to be dismounted without first having to fully or partially dismount the canvas ( 4 ).

1 . Suspended ceiling constituted on the one hand by at least one canvas ( 4 ) tightened by its periphery on support elements ( 1 ) fast with the ceiling and/or the walls of a room, characterized in that it is constituted, on the other hand, by ceiling tiles ( 5 ) held by these support elements with the aid of holding means allowing the tiles ( 5 ) to be dismantled without first having to fully or partially dismantle the canvas ( 4 ).  
   
   
       2 . Suspended ceiling according to  claim 1 , characterized in that the support elements are constituted by rails, namely peripheral rails and median rails ( 1 ) which are held with respect to the ceiling, these latter being provided, on one of their sides, with means for holding the canvas ( 4 ) and, on their other side, with means ( 15 ) for holding the tiles ( 5 ).  
   
   
       3 . Suspended ceiling according to  claim 2 , characterized in that the tiles ( 5 ) are held in simple abutment, at least in part, on the median rails ( 1 ).  
   
   
       4 . Suspended ceiling according to  claim 3 , characterized in that the median rails ( 1 ) are provided, on one of their sides with means for hooking the canvas, and, on their other side, with a horizontal web ( 15 ) intended to receive the tiles ( 5 ).  
   
   
       5 . Suspended ceiling according to  claim 2 , characterized in that the hooking means of the median rail ( 1 ) are constituted by two parallel vertical flanges ( 9 ,  11 ), namely a first flange ( 9 ) disposed towards the canvas ( 4 ), and a second flange ( 11 ) disposed towards the tiles ( 5 ), the inner wall ( 11   a ) of the second flange ( 11 ) being provided with a shoulder ( 17 ) adapted to receive, in simple abutment, the free end of a border ( 25 ) integral with the canvas ( 4 ), so as to ensure holding of the latter stretched.  
   
   
       6 . Suspended ceiling according to  claim 5 , characterized in that the shoulder ( 17 ) is disposed on the lower part of the second flange ( 11 ).  
   
   
       7 . Suspended ceiling according to  claim 6 , characterized in that said first and second flanges ( 9 ,  1 ) have the same length.  
   
   
       8 . Suspended ceiling according to  claim 2 , characterized in that the upper part of the parallel flanges ( 9 ,  11 ) terminates in a horizontal web ( 10 ) of which the two ends terminate in two small vertical flanges ( 28 ) which extend upwardly and close at their respective upper parts by two horizontal borders ( 31 ), so as to form a slideway ( 29 ) intended to receive a slide block ( 30 ) in the form of a parallelogram and of which the width (e 1 ) is smaller than the opening of width (e 2 ) separating the two borders ( 31 ).  
   
   
       9 . Suspended ceiling according to  claim 3 , characterized in that the hooking means of the median rail ( 1 ) are constituted by two parallel vertical flanges ( 9 ,  11 ), namely a first flange ( 9 ) disposed towards the canvas ( 4 ), and a second flange ( 11 ) disposed towards the tiles ( 5 ), the inner wall ( 11   a ) of the second flange ( 11 ) being provided with a shoulder ( 17 ) adapted to receive, in simple abutment, the free end of a border ( 25 ) integral with the canvas ( 4 ), so as to ensure holding of the latter stretched.  
   
   
       10 . Suspended ceiling according to  claim 4 , characterized in that the hooking means of the median rail ( 1 ) are constituted by two parallel vertical flanges ( 9 ,  11 ), namely a first flange ( 9 ) disposed towards the canvas ( 4 ), and a second flange ( 11 ) disposed towards the tiles ( 5 ), the inner wall ( 11   a ) of the second flange ( 11 ) being provided with a shoulder ( 17 ) adapted to receive, in simple abutment, the free end of a border ( 25 ) integral with the canvas ( 4 ), so as to ensure holding of the latter stretched.  
   
   
       11 . Suspended ceiling according to  claim 3 , characterized in that the upper part of the parallel flanges ( 9 ,  11 ) terminates in a horizontal web ( 10 ) of which the two ends terminate in two small vertical flanges ( 28 ) which extend upwardly and close at their respective upper parts by two horizontal borders ( 31 ), so as to form a slideway ( 29 ) intended to receive a slide block ( 30 ) in the form of a parallelogram and of which the width (e 1 ) is smaller than the opening of width (e 2 ) separating the two borders ( 31 ).  
   
   
       12 . Suspended ceiling according to  claim 4 , characterized in that the upper part of the parallel flanges ( 9 ,  11 ) terminates in a horizontal web ( 10 ) of which the two ends terminate in two small vertical flanges ( 28 ) which extend upwardly and close at their respective upper parts by two horizontal borders ( 31 ), so as to form a slideway ( 29 ) intended to receive a slide block ( 30 ) in the form of a parallelogram and of which the width (e 1 ) is smaller than the opening of width (e 2 ) separating the two borders ( 31 ).
