A castor assembly structured for use in combination with or independently of a dolly or other support platform including a one piece base comprising a housing and a head integrally connected to the housing and extending radially outward from one end thereof. The housing includes an open interior and a open end structured to movably retain a surface engaging roller ball therein. A retaining portion may be formed on said base in cooperative relation with said head so as to secure a support platform to the base when in a first operative position. A second operative position comprises said head disposed in engagable and at least partially supporting relation to an object while the base is not secured to or used in combination with a dolly or other support platform.

A castor assembly as recited in claim 1 wherein said plurality of housing segments are flexibly attached to said head and extend outwardly therefrom towards said first open end. 3. A castor assembly as recited in claim 2 wherein said plurality of housing segments are collectively disposed in surrounding relation to said open interior and include free ends terminating at and at least partially defining a periphery of said open end. 4. A castor assembly as recited in claim 3 wherein adjacent ones of said plurality of housings segments are disposed in spaced relation to one another along at least a portion of their respective lengths. 5. A castor assembly as recited in claim 2 wherein each of said housing segments includes an interior surface having an at least partially concave configuration, said interior surfaces at least partially defining said open interior and said concave configurations collectively and at least partially corresponding to an outer surface of said roller ball. 6. A castor assembly as recited in claim 1 further comprising a retaining portion disposed on said base intermediate said head and said first open end, said retaining portion structured to secure a support platform to said base. 7. A castor assembly as recited in claim 6 wherein said retaining portion is disposed on said exterior surface of said housing adjacent an under portion of said head; said head and said retaining portion cooperatively disposed and structured to retain the support platform on an exterior of said base in confronting relation to said under portion of said head. 8. A castor assembly as recited in claim 7 wherein said retaining portion comprises a recess formed in said exterior surface of said housing, said recess dimensioned to receive and removably retain the support platform therein. 9. A castor assembly as recited in claim 6 wherein said housing comprises a plurality of housing segments having one end connected to said head and an opposite end terminating at and at least partially defining a periphery of said first open end. 10. A castor assembly as recited in claim 9 wherein said retaining portion comprises a plurality of recess segments each formed in an exterior surface of a different one of said housing segments, said plurality of recess segments collectively dimensioned and disposed to removably receive and movably retain the support platform on said base. 11. A castor assembly as recited in claim 1 wherein said head is disposable in confronting at least partially supporting relation to the object when in an operative position. 12. A castor assembly as recited in claim 11 wherein said head comprises an outer surface configured and structured to at least temporarily maintain said confronting, at least partially supporting relation of said head with the object. 13. A castor assembly structured for use in combination with or independently of a support platform, said castor assembly comprising: a one piece base including a housing and a head integrally connected to one end of said housing,said housing including an open interior and an open end disposed in communicating relation to said open interior at an opposite end of said housing relative to said head,a roller ball disposed within said open interior and at least partially extending outwardly therefrom through said open end,a retaining portion formed on said base intermediate said head and said open end, said retaining portion and said head cooperatively disposed and structured to collectively and removably secure said base to the support platform when in a first operative position,said first operative position further comprising said base extending through the support platform and said head and said open end disposed on opposite sides of the support platform, andsaid base disposable in a second operative position comprising said head disposed in confronting, at least partially supporting relation to an object, when said base is not secured to the support platform. 14. A castor assembly as recited in claim 13 wherein said housing comprises a plurality of housing segments disposed in spaced relation to one another and each having an outer end terminating at and at least partially defining a periphery of said open end; each of said housing segments including an interior surface having an at least partially concave configuration; said interior surfaces at least partially defining said open interior and said concave configurations collectively and at least partially corresponding to an outer surface of said roller ball. 15. A castor assembly as recited in claim 13 wherein said retaining portion comprises a recess formed in an exterior surface of said housing, said recess dimensioned to receive the support platform therein, said recess and said head cooperatively disposed on said base to collectively retain the support platform on said base. 16. A castor assembly as recited in claim 13 wherein said first operative position and said second operative position comprise said head disposable in at least partially supporting relation to the object being supported; said head extending radially outward from said housing and beyond an exterior surface thereof, said head comprising an outer surface portion structured to restrict removal of a supported object from said confronting, at least partially supporting relation with said head. 17. A castor assembly as recited in claim 13 wherein said first operative position further comprises said base extending through the support platform concurrently to an under portion of said head disposed in abutting, confronting relation with an outer portion of the support platform and said roller ball and said head being located on opposite sides of the support platform. 18. A castor assembly as recited in claim 13 wherein said retaining portion is dimensioned and structured to movably connect the support platform to said base, when said base is in said first operative position. 19. A castor assembly attachable to a support platform and structured to at least partially support an object, said castor assembly comprising: a base including a head portion and a housing removably connected to one another,said head portion including a head and a body fixedly connected to said head,said head having a greater diameter than a transverse dimension of said body and extending radially outward therefrom,a retaining portion at least partially formed on said body adjacent said head, said retaining portion and said head cooperatively structured to removably retain the support platform connected to said base when said head portion and said housing are connected to one another,said base removably disposed in an operative position on the support platform; and said operative position comprising said head portion passing through the support platform into removable connection with said housing and said head and said housing concurrently disposed on opposite sides of the support platform, anda movable support attached to said housing in supporting relation to said base. 20. A castor assembly as recited in claim 19 wherein said removable connection of said head portion comprises said body passing through the support platform and at least partially disposed within an interior of said housing into removable attachment with said interior of said housing.
