  • Patent number: 12329330
    Abstract: A self-lowering toilet seat system includes a toilet bowl and a toilet seat. The system includes a hinge rotatably coupling the toilet seat and the toilet bowl. The hinge is configured so that the toilet seat is transitionable between a down position and an up position. A lowering device is configured to self-lower the toilet seat towards the down position. A fixedly sealed hinge housing has a delay device therein. The delay device is configured to cause a seat time delay before the lowering device causes the toilet seat to lower towards the down position. The delay device is engaged by applying a seat lifting force to raise the toilet seat towards the up position and removing the seat lifting force from the toilet seat. The delay device is configured to reset the seat time delay when the lifting force is reapplied before the delay device has expired.

  • Patent number: 12193617
    Abstract: A self-lifting toilet seat system includes a toilet seat configured to be sat upon by a user. The system has a hinge configured to rotatably couple the toilet seat and a toilet bowl. The hinge is configured so that the toilet seat is transitionable from an up position to a down position. A lifting system is configured to raise the toilet seat towards the up position. A sealed hinge housing has at least a portion of a delay system therein. The delay system is configured to cause a time delay before the lifting system causes the toilet seat to self-lift towards the up position. The delay system is configured so that the time delay begins after removal of a threshold downward force on the toilet seat.
