ABSTRACT:
A hinge mechanism capable of making fluidic damping action ineffective or reducing fluidic damping action to the least possible extent so that the seat or the seat lid of a toilet bowl can be lightly raised when raising the seat or the seat lid, holds in the seat or the seat lid in a self-supporting state. Fluidic damping action is so that the seat or the seat lid can be turned gently when turning the seat or the seat lid to its fully lowered position and prevent damaging a fluid damping mechanism by overloading. The hinge mechanism comprises: a bracket fixedly mounted on the toilet bowl; a shaft having one end fixedly supported on the bracket, and extended in a horizontal position; a rotary drum coaxially and rotatably mounted on the shaft so as to be slightly axially slidable to hold the seat or the seat lid; a compression spring wound around the shaft and compressed in an annular space between the shaft and the rotary drum to bias the rotary drum in one direction; and a fluid damping mechanism disposed between the stationary shaft and the rotary drum and provided with valves.
