Toilet seat with built-in lift apparatus

Abstract

Toilet seat with built-in lift apparatus comprises a toilet seat that has built-in long pivot-rod whose each end has installed a small gear, a U-shaped lever whose each end has installed a large gear each and a reverse U-shaped plate fastener that has two side-wings. The U-shaped lever is fastened onto side-wings of U-shaped plate fastener. The toilet seat and the plate fastener are fastened onto toilet with a pair of bolts. Both small gears and large gears catch snugly each other. When large gears rotate clockwise small gears rotate counter clockwise and vice versa. Man steps downward the U-shaped lever to lift toilet seat and releases slowly U-shaped lever to lower toilet seat.

1 . Toilet seat with built-in lift apparatus comprising a toilet seat, a pair of small gears, a pair of large gears, a reverse U-shaped plate fastener, two bolt fasteners and a U-shaped gear-lever. 
   
   
       2 . The said toilet seat in  claim 1  has a built-in long rod as pivot that is installed at the rear end and the said a pair of small gears in  claim 1  that each gear is installed at the end of the said built-in long rod. Wherein the said built-in long rod is as long as the top of toilet where the pivot of toilet seat is located and is fastened onto toilet by bolt-fastener. 
   
   
       3 . The said reverse U-shaped plate fastener in  claim 1  is a U-shaped plate that is placed on top of toilet under the said built-in long rod in  claim 2  and has a top plate and two side-wings. Wherein the said top plate is as long as the said built-in rod in  claims 2  and  3  and has two holes in the middle to pass the said two bolt-fasteners in  claim 1  that hooks the said built-in long rod in  claims 2  and  3 . Wherein the said two side-wings each has a central hole to catch the said U-shaped gear-lever in  claim 1 . 
   
   
       4 . The said U-shaped gear-lever in  claims 1  and  3  is a U-shaped lever whose each end has installed one of the said a pair of large gears in  claim 1 . Wherein the said large gear each has a bolt installed at the center of inner side to pass through the said central hole of side-wings in  claim 3  and has a nut to screw onto it. Wherein the said large gears is preferably twice as large as the said small gears in  claims 1  and  2 . 
   
   
       5 . The said a pair of small gears in  claims 1 ,  2  and  4  catch snugly the said a pair of large gears in  claims 1  and  5  and rotate in reverse direction to the said a pair of large gears.
