thereon, ~ es~eiving and retai~ g a leaf spring 60 extending in a generally lcngitudinal direction. In the h~nge a~bly 30 depicted in the dr~ings, the leaf ~pring 60 is generally w~rted ln a medial portia~ ween t~e as&ociated ~pring ~eats 54 ~t app~ite ends of the le~ ring 60. m.,8, w~en the hin~ ~ser~ly 30 i~
as#~nb;led, the leaf spring 60 ~8` 81 y engaged and resiliently dbflected ky ~he cam member 36 durlng pivokal rotational mivement o~
the vanity door 24 relative t~ the vanity housing æ. ~he deflected leaf spring 60 exerts a resilient bdasing for oe on the cam memker 36 in a generally lateral dlrectiQn~ generally toward the longitudinal ax~s o~ rotaticn extending through the pivot pin 50~ and thus al~o tends to res~liently bias the vanity dbor 24 and the vani~y hGusing 22 in generally cppoRi~e directions ~way from one another.
m e leaf ~pring 60 funct~ons to res~liently but releasably mai~tain the Yanity dbor 24 in p¢edbtermined rotational orientations relative to the vanity housing 22 when the leaf spring 60 i~ engaged by the dwell Fortions 40 and 42 o~ ~he cam member 36. ~he laterally-enlarged loke p~rtion 44 o the c~m ~ember 36 preferably has either ~he narrcw interEection of t~he dwell portions 40 and 42 ~hown in F~gures 5 and 6, or ~n oetional rounded or ~rcuate ~hape, confronting the le2f ~pring 60. Thu8~ the resllient bia~ing ~oroe of the leaf 0pring 60 tends to ~e~iliently and forcibly urge or self-Fro~el the vanity door 20 t4ward or into one of ~uch predete~mined rotational orientat$ ~ relat$~e to the v~nity hous$ng 22 when tbe lea~ Epring 60 i~ engaged by ~he l~terally-enlarged lobe portlon 44. ~his e~fect re~ults ps~marily ~rom the ~ct that the leæ~ ~pring 60 1~ pre~erably re~lien~ly deflected ~n a late~al . , , ~ .

Although such relative rokational orientatians cDrrespond to GQen and closed posit~ons of the vanity dbor 24 in the hinge assembly 30 depicted in the dr~ings, one skilled in the art will readily ap~rec~ate that the dwell portians of the c~m m~mber in any giYen application can be Fee~elected tD result ln any number of other Fredeternined relative rotational orienkation~.
In ~ddition to ~he above, it ~hould also be noted that although the exemplary hinge assembly 30 depicted in the dlawing~ includes the cam member 36 and the pivot bearing member~ ~2 on the vanity door 24, , with the pivok p~n 50, the leaf spring 60, and the related ~upporting~
