Plasterboard Panel for Access to a Compartment

Abstract

In a plasterboard panel a first plasterboard sheet has an opening delimited by a first outer zone of the first sheet; a second plasterboard sheet forms a door which can be connected to the opening in the first sheet, the second plasterboard sheet comprising a second outer zone delimiting the door. The panel also comprises holding means for stably connecting the door to the opening. The first outer zone is tapered transversally to the plane in which the panel lies and narrows from a first flat surface of the first sheet to a second flat surface of the first sheet opposite the first flat surface. The second outer zone is tapered transversally to the plane in which the panel lies and narrows from a first flat surface of the second sheet to a second flat surface of the second sheet opposite the first flat surface.

1 . A plasterboard panel for access to a compartment comprising:
 a first plasterboard sheet having a first flat surface and a second flat surface opposite the first flat surface; the first plasterboard sheet having an opening extending between the first flat surface and the second flat surface; the first plasterboard sheet also comprising a first outer zone delimiting the opening, extending at least partly in the same plane as the first flat surface;   a second plasterboard sheet having a first flat surface and a second flat surface opposite the first flat surface, forming a door which can be connected to the opening in the first sheet; the second plasterboard sheet comprising a second outer zone delimiting the door;   holding means for stably connecting the door to the opening, for a door closed configuration, and for at least partly removing the door from the opening, for a door open configuration;   the door closed configuration forming a single plane between the first flat surface of the first plasterboard sheet and the first flat surface of the second plasterboard sheet; the panel being characterised in that:   the first outer zone is tapered transversally to the plane in which the panel lies and narrows from the first flat surface to the second flat surface of the first sheet;   the second outer zone is tapered transversally to the plane in which the panel lies and narrows from the first flat surface to the second flat surface of the second sheet.   
   
   
       2 . The panel according to  claim 1 , wherein the first outer zone comprises first outer edges facing the opening of the first sheet and the second outer zone comprises second outer edges around the outside of the door; the tapering of the first outer zone being formed by a portion inclined at a first constant angle formed between the first flat surface of the first sheet and the first edge; the tapering of the second outer zone being formed by a portion inclined at a second constant angle formed between the first flat surface of the door and the second edge. 
   
   
       3 . The panel according to  claim 2 , wherein the first angle and the second angle are supplementary angles. 
   
   
       4 . The panel according to  claim 2 , wherein a portion of the first flat surface of the first sheet extends without interruption forming at least the first outer edges and wherein a portion of the first flat surface of the second sheet extends without interruption forming at least the second outer edges. 
   
   
       5 . The panel according to  claim 1 , comprising at least one lock acting between the door and the first sheet in the door closed configuration. 
   
   
       6 . The panel according to  claim 1 , wherein the holding means comprise anchoring means, acting between the door and the first outer zone. 
   
   
       7 . The panel according to  claim 2 , wherein the holding means comprise at least one hinge, acting between the first edges of the first outer zone and the second edges of the second outer zone. 
   
   
       8 . The panel according to  claim 2 , wherein the holding means comprise:
 at least one hinge fixed; to the first sheet at the opening and connected to the door by at least one shaped bracket which allows the door to open without interfering with the first outer edges of the first outer zone;   at least one telescopic cylinder having a first end hinged to the door and a second end hinged to the first sheet;   the axes of rotation of the first and second ends of the telescopic cylinder being parallel with the axis of rotation formed by the hinge.   
   
   
       9 . The panel according to  claim 1 , wherein the door comprises a plurality of through-slits forming a ventilation grille. 
   
   
       10 . The panel according to  claim 1 , wherein the first outer zone is formed by an extension of the first plasterboard sheet projecting in the opening to form a first frame. 
   
   
       11 . The panel according to  claim 10 , wherein the extension of the first sheet is folded on the second flat surface of the first sheet. 
   
   
       12 . The panel according to  claim 11 , wherein the extension of the first sheet is in contact with the second flat surface of the first sheet. 
   
   
       13 . The panel according to  claim 1 , wherein the second outer zone is formed by an extension of the second plasterboard sheet to form a second frame. 
   
   
       14 . The panel according to  claim 13 , wherein the extension of the second sheet is folded on the second flat surface of the second sheet. 
   
   
       15 . The panel according to  claim 14 , wherein the extension of the second sheet is in contact with the second flat surface of the second sheet.
