Foldable sheet for forming support structure on roof

Abstract

A cardboard or plastic sheet can be folded into a support structure for supporting an object on an inclined roof. The sheet has multiple fold lines which, when used to fold the sheet, form a base for mounting on the roof and a shelf for supporting the object at an angle relative to the roof. A roofing assembly includes bundles of roofing shingles and a sheet between the bundles. The sheet has multiple fold lines which, when used to fold the sheet, form a support structure for supporting an object on an inclined roof.

What is claimed is:  
     
         1 . A sheet made predominantly from a material selected from cardboard and plastic, and combinations thereof, the sheet being adapted to be folded into a support structure for supporting an object on an inclined roof, the sheet having multiple fold lines which, when used to fold the sheet, form a base adapted for mounting on the roof and a shelf adapted for supporting the object at an angle relative to the roof.  
     
     
         2 . A sheet according to  claim 1  further having a cut line which is pre-cut during manufacture of the sheet, or which is adapted for cutting during construction of the support structure.  
     
     
         3 . A sheet according to  claim 1  further having a foot portion which, when the sheet is folded, is adapted for holding the support structure on the roof.  
     
     
         4 . A sheet according to  claim 3  further having a mark on the foot portion indicating a location adapted for insertion of a fastener.  
     
     
         5 . A sheet according to  claim 1  further having a stop portion which, when the sheet is folded, is adapted for restraining the object.  
     
     
         6 . A roofing assembly comprising bundles of roofing shingles and a sheet between the bundles, the sheet having multiple fold lines which, when the sheet is folded, form at least a portion of a support structure adapted for supporting an object on an inclined roof.  
     
     
         7 . A roofing assembly according to  claim 6 , wherein the support structure includes a base adapted for mounting on the roof and a shelf adapted for supporting the object at an angle relative to the roof.  
     
     
         8 . A roofing assembly according to  claim 6 , wherein the sheet further has a cut line which is pre-cut during manufacture of the sheet, or which is adapted for cutting during construction of the support structure.  
     
     
         9 . A roofing assembly according to  claim 6 , wherein the sheet further has a foot portion which, when the sheet is folded, is adapted for holding the support structure on the roof.  
     
     
         10 . A roofing assembly according to  claim 6 , wherein the sheet further has a stop portion which, when the sheet is folded, is adapted for restraining the object.  
     
     
         11 . A roofing assembly according to  claim 6 , wherein the sheet is made predominantly from a material selected from cardboard and plastic, and combinations thereof.  
     
     
         12 . A roofing assembly according to  claim 6 , wherein the sheet is a first sheet which forms a first portion of the support structure, and further comprising a second sheet between the bundles, the second sheet having a line which, when cut or used to fold the sheet, forms a second portion of the support structure.  
     
     
         13 . A roofing assembly according to  claim 12 , wherein one of the first sheet and the second sheet forms a base adapted for mounting on the roof, and the other of the first sheet and the second sheet forms a shelf adapted for supporting the object at an angle relative to the roof.  
     
     
         14 . A roofing assembly according to  claim 12 , wherein the first sheet and the second sheet have tabs adapted for locking the sheets together.  
     
     
         15 . A support structure for supporting an object on an inclined roof comprising a sheet made from a material which can be folded by hand, the sheet being folded into a support structure which includes a base adapted for mounting on the roof and a shelf adapted for supporting the object at an angle relative to the roof.  
     
     
         16 . A support structure according to  claim 15 , wherein the sheet is cut during construction of the support structure.  
     
     
         17 . A support structure according to  claim 16 , wherein the sheet has lines to indicate locations for folding and cutting.  
     
     
         18 . A support structure according to  claim 15 , wherein the support structure has a foot portion which, when the sheet is folded, is adapted for holding the support structure on the roof.  
     
     
         19 . A support structure according to  claim 15 , wherein the support structure has a stop portion which, when the sheet is folded, is adapted for restraining the object.  
     
     
         20 . A support structure according to  claim 15 , wherein the sheet is made predominantly from a material selected from cardboard and plastic, and combinations thereof.
