摘要:
A disc-shaped throwing toy includes a collapsible shell cooperatively formed by a plurality of segments coupled between a first and second center element and at least one elastic element coupled between at least two of the plurality of segments, each of the plurality of segments includes a first and second segment member operatively coupled together by a hinge wherein corresponding first and second segment members are selectively movable between a first or collapsed position and second or expanded position relative to each other such that as disc-shaped throwing toy with the corresponding first and second segment members in the first or collapsed position relative to each other is thrown the centrifugal force initially maintains the disc-shaped throwing toy in a substantially flat configuration and as the rotational speed of the disc-shaped throwing toy decreases the elastic element causes the corresponding first and second segment elements to move to the second or expanded position relative to each other whereby the disc-shaped throwing toy forms a substantially spherical configuration.
