Abstract: There is disclosed herein a cup holder assembly particularly adapted to be secured to a variety of supporting surfaces which cup holder assembly is uniquely designed to support cups having downwardly converging side walls such as for example conventional paper cups or the like. The cup holder assembly includes a cup holding member having a generally circular opening provided therein which is designed to receive a portion of the cup in a manner so as to supportingly engage the side walls thereof. The cup holding member is designed to be supported upon a variety of adjacent surfaces by means of a mounting assembly. In one form the mounting assembly includes a support member adapted to removably receive and support the cup holding member in cantilevered relationship thereto and which support member is particularly suited to be secured to a generally cylindrical member such as the handle bars of a bicycle or the like by means of a strap clamp.
