Combination Heightened Toilet Seat Assembly

Abstract

A combination heightened toilet seat assembly includes a fixed base and a heightened seat. The fixed base has a mounting face having two fitting grooves. The heightened seat has two distal end faces each having a fitting protrusion. In assembly, the heightened seat is movable downward, with the fitting protrusion of each of the distal end faces of the heightened seat being slidable into each of the fitting grooves of the mounting face of the fixed base to combine the heightened seat with the fixed base. On the contrary, the heightened seat is movable upward, with the fitting protrusion of each of the distal end faces of the heightened seat being movable and detachable from each of the fitting grooves of the mounting face of the fixed base to detach the heightened seat from the fixed base.

1 . A combination heightened toilet seat assembly comprising:
 a fixed base; and   a heightened seat connected with the fixed base;   wherein:   the fixed base is mounted on a top portion of a toilet bowl;   the fixed base defines a bottom face and a top face opposite to the bottom face;   the fixed base has a side provided with a mounting face which has two fitting grooves spaced from each other;   each of the fitting grooves of the mounting face of the fixed base extends from the top face to the bottom face of the fixed base;   the heightened seat has a substantially U-shaped profile and defines a bottom face and a top face opposite to the bottom face;   the heightened seat has two distal end faces arranged in a symmetrical manner;   each of the distal end faces of the heightened seat has a fitting protrusion;   the fitting protrusion of each of the distal end faces of the heightened seat extends from the bottom face to the top face of the heightened seat;   the heightened seat is movable downward relative to the fixed base, with the fitting protrusion of each of the distal end faces of the heightened seat being slidable into each of the fitting grooves of the mounting face of the fixed base to combine the heightened seat with the fixed base; and   the heightened seat is movable upward relative to the fixed base, with the fitting protrusion of each of the distal end faces of the heightened seat being movable and detachable from each of the fitting grooves of the mounting face of the fixed base to detach the heightened seat from the fixed base.   
     
     
         2 . The combination heightened toilet seat assembly of  claim 1 , wherein each of the fitting grooves of the mounting face of the fixed base has an arcuate cross-sectional profile, and the fitting protrusion of each of the distal end faces of the heightened seat has an arcuate cross-sectional profile. 
     
     
         3 . The combination heightened toilet seat assembly of  claim 1 , wherein each of the fitting grooves of the mounting face of the fixed base has a dovetailed cross-sectional profile, and the fitting protrusion of each of the distal end faces of the heightened seat has a dovetailed cross-sectional profile.
