Removable panel for suspended ceiling and suspended ceiling integrating such a removable panel

Abstract

A removable panel includes a fixed section, an opening section able to be reversibly nested in the fixed section, at least one sling fastened to the fixed section at a first end and reversibly fastened to the opening section at a second end. The removable panel also includes at least one attachment means making it possible to maintain the opening section engaged in the fixed section. Each attachment means including a central portion in pivot connections with the opening section, the central portion having at an upper end an attachment portion intended for coming into contact with the fixed section, and at a lower end a manipulation portion. A suspended ceiling is also provided and includes an assembly of modular panels at least one of which is the removable panel.

What is claimed is: 
     
         1 . A removable panel including:
 a fixed section;   an opening section configured to be reversibly nested, at least partially, in said fixed section;   at least one sling fastened to said fixed section at a first end and reversibly fastened to said opening section at a second end;   
       said removable panel being characterised in that:
 the opening section includes at least one attachment means making it possible to maintain said opening section engaged in said fixed section, each attachment means including a central portion fastened as a pivot connection with the opening section, said central portion having at an upper end an attachment portion intended for coming into contact with the fixed section, and at a lower end a manipulation portion, and 
 the fixed section includes at least one plateau and at least one notch configured to cooperate with said attachment means. 
 
     
     
         2 . The removable panel according to  claim 1 , including a closed position wherein the attachment portion is bearing on the plateau of the fixed section, and an open position wherein the attachment portion is pivoted in the notch. 
     
     
         3 . The removable panel according to  claim 1 , wherein the notch of the fixed section includes an “L” or “inverted L” shape, a longitudinal side of the notch being aligned with an edge of the fixed section, and the plateau is located in continuity with said notch. 
     
     
         4 . The removable panel according to  claim 2 , wherein the attachment portion is a substantially flat portion, and in the closed position, said attachment portion is in face-to-face contact with the plateau of the fixed section. 
     
     
         5 . The removable panel according to  claim 1 , characterised in that said removable panel includes moreover at least one safety device able to provide a fastening of the at least one sling to the opening section. 
     
     
         6 . The removable panel according to  claim 5 , characterised in that the opening section includes at least one groove, each groove being associated with a safety device, and in that each safety device includes an arm, and a first rivet and a second rivet disposed on either side of said associated groove, the arm being fastened by means of the first rivet to the frame of the opening section by a first end of said arm, so that the arm is able to pivot about the axis of said rivet by manual action, the second rivet being intended for cooperating with a hole of said arm to lock said safety device. 
     
     
         7 . The removable panel according to  claim 1 , characterised in that the fixed section is a parallelepiped frame having a square section, of which a vertical branch is disposed on the inside side of said frame, and of which a horizontal branch includes said notch. 
     
     
         8 . The removable panel according to  claim 1 , characterised in that the central portion has a substantially flat and rectangular shape, the attachment portion extends in a plane substantially perpendicular to the central portion from the upper end of said central portion, and the manipulation portion is a substantially flat portion extending from the lower end of said central portion in a direction forming an angle substantially comprised between 0 and 180 degrees with a direction normal to said central portion. 
     
     
         9 . The removable panel according to  claim 8 , characterised in that the angle formed by the manipulation portion and the direction normal to said central portion is substantially comprised between 30 and 90 degrees. 
     
     
         10 . A suspended ceiling including an assembly of modular panels characterised in that it includes at least one removable panel according to  claim 1 . 
     
     
         11 . The suspended ceiling according to  claim 10 , characterised in that said suspended ceiling is an acoustic suspended ceiling and in that the modular panels as well as the at least one removable panel are of the type:
 aerated filter panel comprised of a framework covered with a perforated textile cover stretched over said framework or;   absorbent panel comprised of a framework supporting an absorbent wad and a microporous veil, the assembly being covered with a textile cover.   
     
     
         12 . The suspended ceiling according to  claim 10 , characterised in that the modular panels are maintained together by linear junction systems providing a flatness of said suspended ceiling.
