Abstract
A discus-like hurling toy is formed of a disc of cloth having a gathered and downturned hemmed edge. A string of regularly spaced small metallic weights are fixed within the hem. The device may be worn as a hat or folded or crumpled for storage and when hurled with a rotational motion the centrifugal force acting on the weights extends the device so that it exhibits aerodynamic properties to prolong its flight and give it a true trajectory. Alternative embodiments employ a stranded metal cable and an annular sand bag as weights.
Claims14
A device comprising a disc-shaped section of flexible, non-resilient sheet material having an edge section with an extension in a direction normal to the nominal plane of the disc when the sheet and edge section are extended, and an annular distributed weight formed of a material having a density substantially in excess of the sheet material connected to said laterally extending edge, whereby the device may be readily folded or crumpled, and when hurled with a rotational motion the centrifugal forces acting on the weights will cause the device to assume an extended position so as to exhibit aerodynamic properties.
