发明名称 Rock and roll recreational toy
摘要 An amusement toy comprising an annular body which has an outer peripheral surface containing profiled hoop edge portions at its outboard edges which are joined by a squat barrel-shaped portion, such edge portions being integral with vertical side wall portions which are somewhat bulged in an outboard direction and which terminate at an inner rim. A gripping bar joins the rims and a cover is rigidly connected across the rims which bulges inwardly towards the center of the toy to form with peripheral surfaces a channel of about 120 DEG of arc, the end of the channel being about 30 DEG of arc from the bar. All parts of the toy except the gripping bar are composed of a rigid resin material and all surfaces are compound curves. A person who places himself in the channel and holds onto the gripping means is capable of causing the toy to rock on a level surface and by sufficient rocking to roll over whereby the cover joining the rims holds the person within the channel.
