Upright lift toilet seat

Abstract

Upright lift toilet seat comprises one toilet seat with an upward-turned rear end, two pull strings and two weights. Upright lift toilet seat is kept at upright position by weight through the mechanism of seesaw and can be turned to horizontal position by hand. Male has to lift ordinary toilet seat to urinate to prevent toilet seat from being wetted by urine. If toilet has installed upright lift toilet seat then male does not have to raise toilet seat every time before urinating.

1 . Upright lift toilet seat comprising a toilet seat with an upward-turned rear end, two Z-shaped pivot anchors, two pull strings with attached hook apparatus and two weights with hook apparatus. 
     
     
         2 . Upright lift toilet seat of  claim 1  wherein said toilet seat with an upward-turned rear end is a toilet seat which has one upward-turned rear end. Wherein said upward-turned rear end has two identical slots, one at each side. Each one of said two identical slots has installed two pivots which are one small pivot and one large pivot. Wherein said small pivot is across said slot and fixed in each side wall and near upper end of said slot. Wherein said large pivot is across said slot and fixed in each sidewall and near lower end of said slot. Wherein said two identical slots separate each other at a distance which is preferable equal to the distance of separation of two toilet seat anchor bolts canals on top of toilet frame of toilet and in front of toilet water tank to fasten toilet seat onto toilet. Wherein said slot is upward-turned at an angle in correspondent to that of said upward-turned rear end. Wherein said slot is about 1.5 to 4 inches long and the longer the said slot is the greater the leverage will be. Wherein said upward-turned rear end is best 45 degrees turned upward for the best leverage effect. Wherein said large pivots of said two identical slots align. Wherein said small pivots of said two identical slots align. 
     
     
         3 . Upright lift toilet seat of  claim 1  wherein said two Z-shaped pivot anchors are identical and each one of said two Z-shaped pivot anchors has one base plate, one built-in rear tube which connects the rear end of said base plate at right angle and points downwardly, one built-in front toilet seat holder blade which connects the front end of said base plate at right angle and points upwardly and one nut. Wherein said built-in rear tube can pass through built-in toilet anchor bolt canal which locates on each side of top frame of toilet in front of toilet water tank to hold anchor bolt of toilet seat. Wherein said built-in rear tube has one threaded lower end. Wherein said nut can screw onto said threaded lower end. Wherein said built-in front toilet seat holder blade is about 1.5 inches to 4 inches in length which is equal to or preferable a little bit greater than that of said base plate and said upward-turned rear end of  claim 2  and has one side pivot canal at the middle of upper end. Wherein said side pivot canal can be passed loosely through by said large pivot of  claim 2 . 
     
     
         4 . Upright lift toilet seat of  claim 1  wherein said two pull strings with attached hook apparatus are identical. Each one of said pull strings can be nylon string or cable or rope and has one attached ring at upper end and one attached lower hook apparatus at the lower end. Each one of said pull strings can pass loosely through said built-in rear tube of  claim 3 . Wherein said attached ring at upper end can be passed loosely by said small pivot of  claim 2 . Wherein said attached lower hook apparatus can hook said weight of  claim 1 . 
     
     
         5 . Upright lift toilet seat of  claim 1  wherein said two weights are identical and each one of said weights has one hook apparatus at the center of its top and one shock absorber sponge which is attached at its lower end. Wherein said hook apparatus at the center of its top can hook to said attached lower hook apparatus of  claim 4 . The sum of vectors of leverage of said two weights must be greater than vector of leverage of said toilet seat with upward-turned rear end of  claims 1  and  2 .
