Dome trap

Abstract

An improved dome shaped trap for bathroom, kitchen or other sink comprising a dome shaped trap, threadably attached to a cover. The cover comprises a vertical conduit adapted to receive the existing vertical influent drain from the sink, a horizontal conduit adapted to be attached to the existing effluent exit drain, the vertical conduit extending down below the water line, providing an extension for the exisiting influent drain, making the trap easily adjustable to be installed any existing sink. The dome trap is easily removable by hand, by unscrewing it from the cover, to clean out any debris clogging the line or to retrieve any item inadvertently dropped into the sink and down the drain into the dome trap.

I claim:  
     
         1 : A drain trap for a sink having an influent drain line and an effluent exit line comprising, a trap which fits between the influent drain line and the effluent exit line, the trap having a transparent dome shaped lower trap bowl having a cone-shaped indicator fixedly attached to the bottom thereof, the lower trap bowl threadably attached to a sealed cover, a vertical conduit inside of said cover, which is an integral part of said cover and formed monolithically as a part of the cover, the vertical conduit having an inside diameter equal to, or slightly larger than, the influent drain line, the lower end of said vertical conduit extending below the water line in the trap, said vertical conduit adapted to receive the influent drain line, a horizontal conduit exit line above the dome shaped lower trap bowl, the exit line having a flexible conduit segment and being an integral part of the cover, the exit line having an inside diameter equal to or greater than the influent drain line.  
     
     
         2 : The device of  claim 1  further comprising means to seal the connection between influent drain line and the vertical conduit, and the connection between the horizontal conduit exit line and the effluent exit line.  
     
     
         3 : The device of  claim 2  in which said means is a compression nut.  
     
     
         4 : The device of  claim 3  in which said compression nut has an integrated plastic washer.  
     
     
         5 : The device of  claim 3  in which said compression nut has a non-integrated plastic slip washer.  
     
     
         6 : The device of  claim 1  in which the dome trap is made of plastic.  
     
     
         7 : The device of  claim 1  in which the cover, vertical conduit and horizontal conduit are all injection molded monolithically as a single integrated unit.  
     
     
         8 : A drain trap for a sink having an influent drain line and an effluent exit line comprising, a trap which fits between the influent drain line and the effluent exit line, the trap having a dome shaped lower trap bowl, threadably attached to a sealed cover, a vertical conduit inside of said cover, which is an integral part of said cover and formed monolithically as a part of the cover, the vertical conduit having an inside diameter equal to, or slightly larger than, the influent drain line, the lower end of said vertical conduit extending below the water line in the trap, said vertical conduit adapted to receive the influent drain line, a horizontal conduit exit line above the dome shaped lower trap bowl, the exit line being an integral part of the cover and formed monolithically as a part of the cover, the exit line having an inside diameter equal to or greater than the influent drain line.  
     
     
         9 : The device of  claim 8  further comprising means to seal the connection between drain line and the vertical conduit, and the connection between the horizontal conduit and the exit line.  
     
     
         10 : The device of  claim 9  in which said means is a compression nut.  
     
     
         11 : The device of  claim 10  in which said compression nut has an integrated plastic washer.  
     
     
         12 : The device of  claim 10  in which said compression nut has a non-integrated plastic slip washer.  
     
     
         13 : The device of  claim 8  in which the dome trap is made of plastic.
