Deck Drainage System

Abstract

A plurality of interlocking sloped channels, which drain water seeping through the deck into a rain gutter comprises a deck drainage system. Each channel provides a flashing on each side edge, which overlaps the corresponding flashing on the neighboring channel to prevent leakage. The flashings overlap each other on the top surface of the deck joists, and the channels are suspended between the joists, such that they only occupy unused space.

I claim: 
     
         1 . A deck drainage system, comprised of:
 a. a plurality of interlocking sloped channels having a front edge, rear edge, and two side edges;   b. a plurality of flashings;   b. one of said plurality of flashings being a base flashing and being connected to one side edge of said interlocking sloped channel;   c. one of said plurality of flashings being an overlapping flashing and being connected to one side edge of said interlocking sloped channel opposite said base flashing;   d. a plurality of deck joists;   e. wherein said plurality of interlocking sloped channels are suspended between said plurality of deck joists and supported on each side by said plurality of flashings.   
     
     
         2 . The deck drainage system of  claim 1 , wherein one of said plurality of flashings being a rear flashing and being connected to said rear edge. 
     
     
         3 . The deck drainage system of  claim 1 , further comprising a flange; said flange being connected to said overlapping flashing; said flange being configured such that a waterproof seal is formed when said overlapping flashing is placed over said base flashing. 
     
     
         4 . The deck drainage system of  claim 2 , further comprising a flange; said flange being connected to said overlapping flashing; said flange being configured such that a waterproof seal is formed when said overlapping flashing is placed over said base flashing. 
     
     
         5 . The deck drainage system of  claim 1 , further comprising a profile board; said profile board being L-shaped and having a back edge and bottom edge; said back edge being configured to attach to a ledger board of a wall; said bottom edge being configured to attach to said plurality interlocking sloped channels. 
     
     
         6 . The deck drainage system of  claim 2 , further comprising a profile board; said profile board being L-shaped and having a back edge and bottom edge; said back edge being configured to attach to a ledger board of a wall; said bottom edge being configured to attach to said rear flashing. 
     
     
         7 . The deck drainage system of  claim 3 , further comprising a profile board; said profile board being L-shaped and having a back edge and bottom edge; said back edge being configured to attach to a ledger board of a wall; said bottom edge being configured to attach to said plurality interlocking sloped channels. 
     
     
         8 . The deck drainage system of  claim 4 , further comprising a profile board; said profile board being L-shaped and having a back edge and bottom edge; said back edge being configured to attach to a ledger board of a wall; said bottom edge being configured to attach to said rear flashing. 
     
     
         9 . The deck drainage system of  claim 1 , further comprising a rain gutter; said rain gutter being attached to the front edge of said plurality of interlocking sloped channels. 
     
     
         10 . The deck drainage system of  claim 1 , wherein the channels are four feet long. 
     
     
         11 . The deck drainage system of  claim 1 , wherein the channels are six feet long. 
     
     
         12 . The deck drainage system of  claim 1 , wherein the channels are eight feet long. 
     
     
         13 . The deck drainage system of  claim 10 , wherein the deck joists are spaced 16 inches apart and said plurality of interlocking sloped channels are configured and sized to be suspended between said deck joists. 
     
     
         14 . The deck drainage system of  claim 10 , wherein the deck joists are spaced 24 inches apart and said plurality of interlocking sloped channels are configured and sized to be suspended between said deck joists. 
     
     
         15 . The deck drainage system of  claim 11 , wherein the deck joists are spaced 16 inches apart and said plurality of interlocking sloped channels are configured and sized to be suspended between said deck joists. 
     
     
         16 . The deck drainage system of  claim 11 , wherein the deck joists are spaced 24 inches apart and said plurality of interlocking sloped channels are configured and sized to be suspended between said deck joists. 
     
     
         17 . The deck drainage system of  claim 12 , wherein the deck joists are spaced 16 inches apart and said plurality of interlocking sloped channels are configured and sized to be suspended between said deck joists. 
     
     
         18 . The deck drainage system of  claim 12 , wherein the deck joists are spaced 24 inches apart and said plurality of interlocking sloped channels are configured and sized to be suspended between said deck joists. 
     
     
         19 . The deck drainage system of  claim 1 , wherein said base flashing is secured to said deck joist with nails. 
     
     
         20 . The deck drainage system of  claim 2 , wherein said base flashing is secured to said deck joist with nails.
