Drainage System For A Floor

Abstract

A drain system for draining water from a lanai floor to eliminate rainwater build-up on lanai floors and speed-up draining time on such floors. The device is attached to the edge of the Lanai floor and acts as a scupper.

1 . A scupper unit system adapted to incorporate into a metal track, the scupper unit comprising:
 (A) a U-shaped housing having
 (1) a first leg having an opening defined therein, 
 (2) a second leg, 
 (3) a bight section connecting the first and second legs together and being oriented horizontally when the scupper unit is mounted on the floor and is in use, 
 (4) each of the first and second legs having an opening to allow fluid to flow through the first and second legs, and 
 (5) each of the first and second legs having a porous screen coincident with the opening defined in the first and second legs; and 
   B) a pair of wing plates adapted to couple the bight section of the scupper unit to a top surface of the metal track.   
   
   
       2 . The drain unit defined in  claim 1  wherein the mounting elements include self-drilling screws to couple the pair of wing plates to the bight section of the scupper unit and the top surface of the metal track. 
   
   
       3 . The drain unit defined in  claim 1 , wherein the first leg has a C-shaped channel adapted to receive a locking member of a retaining screen. 
   
   
       4 . The drain unit defined in  claim 3  wherein the C-shaped channel is oriented at an oblique angle to the first wall. 
   
   
       5 . The drain unit defined in  claim 1  wherein the U-shaped housing is plastic. 
   
   
       6 . The drain unit defined in  claim 1  wherein the pair of wing plates are co-planar with each other and are offset from a plane containing the bight section. 
   
   
       7 . A scupper unit system adapted to incorporate into a metal track, the scupper unit consisting of:
 (A) a U-shaped housing having
 (1) a first leg having an opening defined therein, 
 (2) a second leg, 
 (3) a bight section connecting the first and second legs together and being oriented horizontally when the scupper unit is mounted on the floor and is in use, 
 (4) each of the first and second legs having an opening to allow fluid to flow through the first and second legs, and 
 (5) each of the first and second legs having a porous screen coincident with the opening defined in the first and second legs; and 
   B) a pair of wing plates adapted to couple the bight section of the scupper unit to a top surface of the metal track.
