ABSTRACT:
Rotatable assemblies for building blocks include a wheel having a peripheral annular cylindrical surface adapted to support building blocks joined thereabout in hinged, end to end fashion, the wheel including annular flanges extending radially outwardly and spaced axially to retain the blocks therebetween. A pivot shaft extends fixedly from a first end surface of the wheel, and is disposed coaxially therewith. The opposed, second end surface includes a coaxially disposed bore dimensioned to receive a pivot shaft of another, similar wheel. A plurality of cylindrical interconnection projections extend from the second end face and are arrayed symmetrically about the bore. A plurality of socket-like interconnection receptacles are formed in the second end face and interspersed with the cylindrical projections. The first end face also includes a like plurality of interconnection receptacles disposed to engage the cylindrical projections of another like-formed wheel for stackable interconnection therebetween. The cylindrical projections also permit connection between the wheel and building blocks having similar interconnection features. A mounting block is also provided, including similar interconnection features and a plurality of shaft-engaging bores extending laterally into side portions of the mounting block.
