ABSTRACT:
A toplet assembly of inner, intermediate and outer toplets has releasable catches on respective housings of the outer and intermediate toplets which secure the intermediate and inner toplets to the outer and intermediate toplets, respectively, nested one inside another, on a common spin axis, for separation during spinning by floor impact, when dropped. The outer and intermediate toplets have respective pivot pins mounted in respective housings for limited axial sliding movement. Springs are connected between respective pivot pins of the outer and intermediate toplets and the respective housings of the intermediate and inner toplets to transmit upward axial movement of the pivot pins thereof, by a first floor impact to the intermediate toplet independently of the pivot pin thereof, thereby releasing only the catch of the outer toplet permitting ejection therefrom both the intermediate and inner toplets secured together as a subassembly and, by a subsequent floor impact of the subassembly, to release the catch of the intermediate toplet, permitting subsequent ejection of the inner toplet from the intermediate toplet. The toplet assembly has an upper face with concentric outer and inner sockets having ratchet teeth and a keyway, respectively, formed by outer and inner toplet housings, respectively, for engagement with ratchet arms and a spring powered spindle of a hand-held spinner.
