Abstract:

A yo-yo having a unique axle design and end pieces capable of retaining POG-shaped inserts. The axle is designed to increase the yo-yo's sleep time as well as to improve the facility with which the yo-yo can be returned from a sleeping condition. The yo-yo's axle includes an axle block that is itself similar in shape to a yo-yo and has a uniquely shaped central groove. The groove has parallel upper sidewalls and a bottom tapered section. The axle block is preferably made of wood and the yo-yo's end members are preferably made of plastic. When a wooden axle block is used with plastic end members, the yo-yo will display the performance advantages that were previously only afforded by wooden yo-yo's while at the same time providing the lower manufacturing costs and high durability of a plastic yo-yo. The yo-yo's end pieces include retaining structure that allows a user to secure a POG-shaped insert to each end piece. The end pieces may include two retaining structures to enable a user to secure two inserts to each end piece with the outer insert overlying and thereby protecting the inner insert.
