  • Patent number: 5488743
    Abstract: A mechanical apparatus used to lift and lower the lid and seat of a toilet by way of a pedal mechanism. The pedal mechanism is connected by levers to a cylindrical lifting device mounted on a shaft. The lifting device is connected to the lid and seat by clasps which are screwed, bolted, riveted, or glued to the toilet lid and seat. The apparatus is held in place by floor braces attached by threaded studs which are fixed to the floor by nuts or by being cemented in depending on the material to be fixed to. An adjusting lever proceeding from the lifting device and connected to the pedal mechanism by a lever, can be adjusted so that the lid and seat stay up after taking the foot away from the pedal. One or both pedals can be actioned at the same time with one foot. The pedal stirrups are cup shaped. Thus the lid and seat can be lifted by pressing down with the sole of the shoe.
