发明名称 Hoop-type amusement device
摘要 An improved hoop-type amusement system is disclosed wherein a plurality of variously sized and shaped connectable components may be selectively interconnected by the user to form simple and complex hoop configurations of a particular size and complex geometric shape. Hoop components may have opposing ends that are adapted for mating engagement with other components to form a hoop of a particular size and shape. In addition, the hoop components may include a radially inner edge defining a recessed groove, and a radially outer edge defining a projecting tongue, or opposite variations thereof, thereby enabling the components to be connected with other components in tongue and groove engagement to form a wide variety of hoop configurations, whether annular or otherwise, thereby enhancing fun and enjoyment.
