Trench Drain System and Method of installation on Level Floor Surface, Particularly for Shower Rooms

Abstract

A trench drain system and method of installation thereof on a level floor surface. An elongate channel member is placed on the floor surface. A preformed elongate sloping member having a thick end tapering to a thin end in inserted into the channel with its thin end closest to the channel drain opening, thereby forming an inclined sloping surface. A grate extends over the channel inlet. The area adjacent the channel is filled to the height of the channel, whereby water thereon flows through the grate into the channel, along the inclined surface and out through the drain opening. The channel can be placed adjacent a vertical wall whereby wall tile may be installed over a channel top edge. The floor area adjacent the channel is filled with preformed sloping sheet members or with plastically formable material positioned at an incline using a floor height setting post.

         20 . A trench drain system for installation on a level floor surface comprising:
 an elongate channel member having a bottom surface, side walls extending upwardly therefrom to side walls top edges, a channel inlet between the side walls top edges and a drain opening, said elongate channel adapted to be placed on a level floor surface; and,   a preformed elongate sloping member having a thick end tapering to a thin end adapted to be inserted into said channel on said bottom surface thereof with said thin end closest to said channel drain opening, said sloping member forming an inclined surface sloping toward said drain opening whereby, by filling an area adjacent said channel over the level floor surface with a material to a height of a channel side wall top edge, liquid on the adjacent fill material can flow into the channel member through the channel inlet and along said inclined surface and out through said channel drain opening.   
     
     
         21 . The trench drain system of  claim 20  further comprising an impermeable covering layer adapted to be placed over and covering the inclined surface. 
     
     
         22 . The trench drain system of  claim 20  further comprising an elongate grate adapted to be located over the channel opening. 
     
     
         23 . The trench drain system of  claim 20  wherein said sloping member is preformed of a material selected from one or more of foam, plastic, and fiberglass. 
     
     
         24 . The trench drain system of  claim 20  wherein said channel drain opening extends through the channel bottom surface and is adapted for connecting a pipe thereto. 
     
     
         25 . The trench drain system of  claim 20  wherein said channel drain opening extends in part through a channel side wall and is adapted for connecting a pipe thereto. 
     
     
         26 . The trench drain system of  claim 20  wherein said elongate channel member comprises one or more preformed channel sections selected from elongate straight channel sections, 90° corner sections, 45° corner sections, 30° corner sections and sections with a drain opening, said channel sections adapted to selectively be adhered to one another for thereby forming the elongate channel member. 
     
     
         27 . The trench drain system of  claim 26  further comprising an impermeable covering layer adapted to be placed over and covering the inclined surface and an elongate grate adapted to be located over the channel opening. 
     
     
         28 . The trench drain system of  claim 20  further comprising an impermeable covering layer adapted to be placed over and covering the inclined surface and an elongate grate adapted to be located over the channel opening. 
     
     
         29 . The trench drain system of  claim 28  wherein said sloping member is preformed of a material selected from one or more of foam, plastic, and fiberglass. 
     
     
         30 - 62 . (canceled) 
     
     
         63 . The trench drain system of  claim 20  comprising a second preformed elongate sloping member having a thick end tapering to a thin end adapted to be inserted into said channel on said bottom surface thereof with said thin end closest to said channel drain opening, said second preformed sloping member also forming an inclined surface sloping toward said drain opening, whereby liquid on the adjacent fill material can flow into the channel member through the channel inlet and along said inclined surfaces of both preformed elongate sloping members and out through said channel drain opening. 
     
     
         64 . The trench drain system of  claim 20  comprising a second preformed elongate sloping member having a thick end tapering to a thin end adapted to be inserted into said channel on said bottom surface thereof, wherein said thick end of said first one of said elongate sloping members has a thickness substantially equal to said thin end of said second elongate sloping member, whereby said ends having substantially equal thicknesses may be placed adjacent one another and the first and second sloping members form a continuous sloping inclined surface. 
     
     
         65 . The trench drain system of  claim 64  further comprising an elongate grate adapted to be located over the channel opening. 
     
     
         66 . The trench drain system of  claim 64  further comprising an impermeable covering layer adapted to be placed over and covering the inclined surfaces of said first and second preformed elongate sloping members. 
     
     
         67 . The trench drain system of  claim 20  wherein at least one of said side walls top edges comprises a tile abutting edge for supporting tile. 
     
     
         68 . The trench drain system of  claim 20  further comprising an elongate grate supporting member having a plurality of large inlet openings adapted to be located over the channel opening and an elongate grate adapted to be located over said grate supporting member. 
     
     
         69 . The trench drain system of  claim 68  wherein said elongate grate supporting member includes a rail for supporting wall tile. 
     
     
         70 .
