  • Patent number: 6290242
    Abstract: A two-wheel inline skate is disclosed having double-action turning means and dual surfaced wheel rollers providing maneuverability, traction, control, and safety in executing turns. The rollers have a two-point stance providing increased leverage and turning force, and are in combination with double-action wheel hangers. The double-action hanger mechanism incorporates elements of a kingbolt platform, a pivot post and a roller-supporting bracket, all emanating from a central hanger crossmember located directly over the roller. The entire hanger frame may be cast in one piece thus constituting a unified and strong hanger for the transmission of turning forces in operating the double-action mechanism.
