  • Toilet seat structure capable of automatically feeding seat covering paper on toilet seat
    Patent number: 4926505
    Abstract: A toilet seat structure capable of automatically feeding a seat covering paper onto a toilet seat substantially comprises a seat covering paper roll disposed at the rear end of a toilet seat body, a seat covering paper feeding mechanism which is provided with a press plate, a seat covering paper tearing mechanism, a control unit for controlling the seat covering paper feeding mechanism and the seat covering paper tearing mechanism and tension applying means for applying tension to the seat covering paper, wherein the seat covering paper which is subjected to tension is cut by applying a pressure thereto by means of the press plate. Due to such construction, the tearing edge of the press plate can be formed in a round shape so that wear of the cutting edge which is generated through the tearing operation can be miminized whereby maintenance or repairing can be also minimized.
