  • Patent number: 4682971
    Abstract: A toy having an elongate handle that terminates in a yoke member that loosely but non-releasably engages one or two hoop members. The hoop members are free to roll on a support surface when the user of the invention runs or walks quickly while holding onto the handle and while maintaining the hoop or hoops substantially in a vertical plane through skilled manipulation of the handle. The yoke member retains the hoop or hoops within a space defined by it at the end of the handle and the yoke member is fixedly secured to the end of the handle; accordingly, the hoop or hoops cannot escape the yoke member and thus cannot escape the control of the user of the invention.
