ABSTRACT:
A roller-ball assembly including a spherically shaped ball but comprising a multi-piece construction including a substantially centrally disposed roller element and two ball segments preferably disposed at opposite ends or sides of said roller element and fixedly secured to one another or to said roller ball structure generally such that the roller element is movable relative to said ball segments. A rolling surface is collectively defined by the external surfaces of the roller element and said ball segments wherein collectively the external surfaces define an external spherical configuration of the roller ball assembly. The external or rolling surface of the roller ball, due to its multi-piece construction, may be defined by one or more external surfaces of said roller element and/or ball segments concurrently engaging a supporting surface over which the roller ball travels. Depending upon the combination of fixed and movable surfaces engaging the supporting surface, the path of travel of said roller ball is determined and may vary greatly.
