Abstract: A hinge mechanism for controlling the operation of a toilet seat cover comprising a base, two pairs of linkages and a cover engaging element. An adjusting bolt and spring provide a structure for adjusting the alignment of the linkages. When the linkages are below their axes of alignment, the adjusting bolt interacts with the base to provide resistance to the opening of the seat cover. An alternative embodiment incorporates magnets on the seat cover and the toilet bowl and relies on the repelling force of the magnets to resist the opening of the seat cover.

Abstract: Apparatus for automatically returning a hinged toilet seat to the lower horizontal position after use of the toilet as a urinal by a male. An operating cylinder is easily attached to the toilet by an adjustable mounting system. A piston is reciprocally disposed in the cylinder and operably linked by a pivoting lever mechanism to the pivoted toilet seat. Movement of the toilet seat to the upper position actuates a biasing spring to urge the piston to move to return the seat to the lower position. The biased piston movement is retarded by operating fluid in the cylinder to delay closing until the male user is finished.

Abstract: A hinged toilet seat that is spring-biased to either an upright or a horizontal position is slowed in its angular rotation to the spring-biased position. The user manually pushes the toilet seat to its use position and after use the toilet seat returns to its spring-biased position. This angular rotation is slowed by the present mechanism wherein the seat is attached to a hinge shaft which has a large gear engaging a small gear on an idler shaft. The rotation of the idler shaft is braked by a slipping clutch, which thereby slows the angular motion of the toilet seat to its spring-biased position.
