Anchor sheet and anchor sheet module

Abstract

This application discloses a relatively thin flexible anchor sheet for installation under carpets or other decorative coverings and a covering module composed of a pre-attached decorative covering and anchor sheet which can be assembled by overlapping hook and loop attachment to an additional covering module to create a complete floor covering of carpet, tile, stone or other material and without substantial attachment to a floor.

1 . A covering module for transportation to a surface to be covered and for attachment to additional modules to form a finished decorative surface comprising: 
 at least one decorative covering having an upper decorative surface and an opposite lower surface, a non-decorative anchor sheet having an upper surface and a non-decorative lower surface, the decorative covering detachably attached across a substantial portion of its lower surface to the non-decorative anchor sheet and the anchor sheet dimensioned so that, after attachment of the decorative covering to the anchor sheet, there is provided an overlap area of upper surface of anchor sheet exposed along one edge of the module, which overlap area is provided with means for detachable attachment of such module to an adjoining module by attachment to an overlapping exposed area of the lower surface of a decorative covering attached to an adjoining module.    
   
   
       2 . A covering module for transportation to a surface to be covered and for attachment to additional modules to form a finished decorative surface comprising: 
 at least one decorative covering having an upper decorative surface and an opposite lower surface, a non-decorative anchor sheet having an upper surface and a non-decorative lower surface, the decorative covering detachably attached across a substantial portion of its lower surface to the non-decorative anchor sheet and the anchor sheet dimensioned so that, after attachment of the decorative covering to the anchor sheet, there is provided an overlap area of lower surface of the decorative covering exposed along one edge of the module, which overlap area is provided with means for detachable attachment of such module to an adjoining module by attachment to an overlap area of the upper surface of an anchor sheet attached to an adjoining module.    
   
   
       3 . A covering module as claimed  claim 1  in which the means for detachable attachment in the overlap area is a part of a hook and loop attachment system.  
   
   
       4 . A covering module as claimed in  claim 3  in which there is provided a temporary covering for the overlap area to prevent attachment of such module to an adjoining module until the module and adjoining module are in the desired position relative to each other.  
   
   
       5 . The covering module of  claim 4  in which the temporary covering is a thin smooth sheet of at least substantially the shape of the overlap area, which cannot bind to either a hook part or a loop part of a hook and loop attachment system.  
   
   
       6 . A covering module as claimed in  claim 5  in which the temporary covering is sufficiently rigid and thin that it can be pushed between the hooks and loops of an attached hook and loop attachment system.  
   
   
       7 . A covering module as claimed in  claim 1  in which the decorative covering and non-decorative anchor sheet are precisely dimensioned and attached off site in pre-determined alignment to provide for a pre-determined overlap area of anchor sheet and decorative covering so that when the anchor sheet of a first module is placed in position next to an adjacent second module the decorative covering of the first module overlaps the second module by a predetermined amount and in a predetermined relation to the decorative covering of the second module.  
   
   
       8 . A covering module as claimed in  claim 7  in which the decorative covering and the non-decorative anchor sheet are attached by means of a complementary hook and loop attachment system covering the lower surface of the decorative covering and the upper surface of the anchor sheet.  
   
   
       9 . The covering module of  claim 1  in which there is provided an additional overlap area of exposed anchor sheet along a second edge of the covering module.  
   
   
       10 . The covering module of  claim 2  in which there is provided an additional overlap area of exposed decorative covering along a second edge of the covering module.  
   
   
       11 . The covering module of  claim 3  in which the lower surface of the anchor sheet is provided with a resilient undercushion.  
   
   
       12 . The covering module of  claim 3  additionally comprising other like modules laid onto a floor and attached to form part of a covering of sufficient mass and rigidity to remain in place on a floor without buckling or movement when subject to normal traffic without attachment to the floor.  
   
   
       13 . The covering module of  claim 12  in which the lower surface of the anchor sheet is provided with a non-slip covering.  
   
   
       14 . A covering module for transportation to a surface to be covered and for attachment to additional modules to form a finished decorative surface comprising: 
 a decorative covering having an upper decorative surface and an opposite lower surface, a non-decorative anchor sheet having an upper surface, the decorative covering attached to the non-decorative anchor sheet and the anchor sheet dimensioned so that, after attachment of the decorative covering to the anchor sheet, there are provided first overlap areas of upper surface of anchor sheet exposed along at least two adjacent edges of the module, and second overlap areas of lower surface of decorative covering exposed along at least two edges opposite the first overlap areas, which overlap areas are provided with means for detachable attachment of such module to an adjoining module by attachment to an overlap area of an adjoining module by means of a complementary hook and look attachment system.    
   
   
       15 . The covering module of  claim 14  which is provided with a temporary hook covering for the overlap area.  
   
   
       16 . The covering module of  claim 15  in which the anchor sheet is covered on its underside with a resilient cushion layer.
