  • Patent number: 5836021
    Abstract: A flexible chain and cord-and-return mechanism used in flushing a toilet. A handle is removably attached to the end of the chain. Various handles are designed in a multitude of shapes including objects relating to a decorating theme, a special occasion or event, or a hobby or interest. The chain passes into the toilet housing through a smooth opening with minimal friction and, within the housing, is connected to a line that passes through a pair of tubes that are slidably connected, the line ending at the tank valve. A spring is fixed to each of the two tubes to return the chain-and-line tank valve actuator to its initial, actuation position after each flushing.
