Patent ID: 7121517

Claim:
A cup holder assembly comprising: a receptacle; a base defining a recess, said base being pivotable with respect to said receptacle between a stored position in which said base is substantially inside of said receptacle and a use position in which said base is at least partially outside of said receptacle; and a partial ring supported by said receptacle and being sufficiently slidable in one direction with respect to said base such that said partial ring is storable substantially within said base when said base is in said stored position and sufficiently slidable in another direction with respect to said base to extend sufficiently out of said base when said base is in said use position to cooperatively form with said base a circumferential support for receiving and at least partially supporting a container; wherein said receptacle forms a grooved track, a portion of said partial ring being captured within said track when said partial ring slides in said one direction with respect to said base, said track thereby guiding said partial ring in forming said circumferential support with said base.
