Abstract
A battery driven toy top containing a motor rotated flywheel enclosed in a domed housing. The top may be spun on either the dome or preferably on the opposite end of the tubular housing and contains noise generators and flashing lights controlled by a novel centrifugal switch.
Claims6
An electrically rotated toy top comprising:
- a tubular first housing;
- an electric motor within said first housing, said motor having an extending rotatable shaft coaxial with said tubular first housing;
- a battery within said tubular first housing, said battery having a first terminal in contact with a first motor terminal and a second terminal in contact with a second motor terminal through a momentary contact electrical switch;
- a rotatable flywheel coupled to said motor shaft, said flywheel including an overlying hollow dome with a small opening therein;
- a second housing, said second housing including a second hollow dome closely overlying the hollow dome on said rotatable flywheel, said second hollow dome having a plurality of openings to form first sound generating means upon relative rotation between said hollow domes;
- and
- second sound generating means including a multiple spoked non-rotatable disc centered around the shaft end of said motor and a resilient member coupled to said rotatable flywheel and extending into the spokes of said disc.
