Abstract
A toy construction set comprises a base block and one or more rotating blocks configured for coupling to the base block, to other rotating blocks, or to both. The base block may be define by an upper surface, a lower surface, and at least one side surface. The base block may comprise a body and a plurality of projections extending outward from the body. Interior cylindrical surfaces may extend between the upper surface and the lower surface of the base block. An upper chamfer may connect the interior cylindrical surface with the upper surface, and a lower chamfer may connect the interior cylindrical surface with the lower surface. The rotating blocks may comprise a hub having a body and a grip extending upward from the upper end of the body. Optionally, the hub may also have a coupling mechanism extending downward from the lower end of the body. Structural elements may emanate from the body of the hub. In various embodiments, the structural elements may comprise a spur gear body, a picture holder support body, a fold-up toy support body, a drive wheel support body, or a driven wheel support body.
