THE BACKGROUND OF THE INVENTION Male urinates several times a day and defecates only once a day. Male has to lift toilet seat every time before urinating to prevent toilet seat from being wetted by urine. Upright lift toilet seat keeps toilet seat at upright position to prevent toilet seat from being wetted by urine when male urinates. Upright lift toilet seat can be turned to horizontal position by hand.
THE SUMMARY OF THE INVENTION Upright lift toilet seat can be installed on a new toilet. Upright lift toilet seat can replace ordinary toilet seat to keep toilet seat at upright position all the time. Upright lift toilet seat also can be converted into ordinary toilet seat by removing attached weights when no male lives in household.
