Toy for amusement and/or exercise
First Claim
1. A toy, comprising a large circular outer hoop, having a substantially round cross-section, a pair of smaller inner circular hoops of substantially identical size mounted in side-by-side relationship within the large outer hoop, the smaller inner hoops being disposed along a diametrical axis of the large outer hoop, and the smaller inner hoops joining each other directly at the approximate center of the large outer hoop, all of the hoops being in substantially the same plane, a substantially U-shaped trackway formed in each of the smaller hoops, each of the trackways having a pair of walls, at least one ball in each of the trackways, whereby the large hoop may be grasped and oscillated in a substantially vertical plane so that the balls in the respective smaller hoops rotate around the respective trackways by reason of centrifugal force, and at least one of the walls of one of the smaller hoops having a plurality of circumferentially-shaped apertures formed therein and communicating with the respective trackway in the one hoop, whereby an audible sound is produced as the respective ball rotates therein.

Abstract
A whirling toy for amusement and/or exercise has a plurality of small hoops in substantially side-by-side spaced relationship in the same plane, and balls are received in respective trackways formed in the hoops. In a preferred embodiment, the hoops are mounted within a large outer hoop. When the outer hoop is manually oscillated, the balls rotate around their respective trackways and are retained therein by reason of centrifugal force. A plurality of circumferentially-spaced apertures are formed in at least one of the smaller hoops, thereby providing an audible sound as the ball whirls around its respective trackway. Alternate embodiments of the invention are also illustrated.
