ABSTRACT:
A toilet-seat flush-valve operating device has an energy transceiver, a connecting portion and a control portion. When adapted to conventional toilet equipment, the device serves to raise and lower the toilet seat automatically. If necessary, a flush-valve opening arrangement is mounted between the energy transceiver and the flush valve so that the device also operates to automatically open the flush valve at the appropriate time. The toilet seat stays at a slightly forwardly inclined vertical position and always tends to fall under its own weight. When an outside force is applied to the control portion, which is capable of transmitting the outside force to the energy transceiver, comprised of a spring and/or a dead weight, the energy transceiver is driven and releases the toilet seat from the control of a linkage mechanism, thereby permitting the seat to fall under its own weight. When the toilet seat falls to lay flat on the toilet bowl and has completed its stoke, it is then possible to withdraw the outside force. Thereafter, the energy transceiver starts to act in a direction opposite to the stroke mentioned above to release the energy gathered from the toilet seat during the stroke. The energy is returned to the toilet seat through the connecting portion as dynamic energy for raising the toilet seat.
