Combination yo-yo and top
The present invention is directed to a combination yo-yo and top device comprising first and second yo-yo body halves, a hollow dowel element detachably connecting one of the yo-yo body halves to the other, a ball bearing element mounted on the hollow dowel element between the yo-yo body halves, a first flywheel assembly having an elongated flywheel axle, wherein the first flywheel assembly is adapted for attachment to the yo-yo body, a second flywheel assembly adapted for attachment to the yo-yo body, a string element having a first end coupled to the hollow dowel element, a power element adapted for attachment to either the first flywheel assembly or the second flywheel assembly to activate both flywheel assemblies, and, at least one removable top component adapted to be secured to the yo-yo body to convert the device from a yo-yo to a top.
1. A combination yo-yo and top device comprising:
a yo-yo body having first and second yo-yo body halves each having an interior side, an exterior side, a rim, and central opening;
an externally threaded hollow dowel element detachably connecting one of the yo-yo body halves to the other;
a ball bearing element mounted on the hollow dowel element between the yo-yo body halves;
a first flywheel assembly having an elongated flywheel axle, wherein the first flywheel assembly is adapted for attachment to the yo-yo body;
a second flywheel assembly adapted for attachment to the yo-yo body;
a string element having a first end coupled to the hollow dowel element;
a power element adapted for attachment to either the first flywheel assembly or second flywheel assembly to activate both flywheel assemblies; and
at least one removable top component adapted to be secured to the yo-yo body to convert the device from a yo-yo to a top.
2. The device of claim 1 wherein the first flywheel assembly further comprises a first flywheel having a central opening and a first gear portion having a central opening, wherein the first gear portion is adjacent the first flywheel, such that the elongated flywheel axle is inserted through the first flywheel central opening and through the first gear central opening when the device is assembled.
3. The device of claim 1 wherein the second flywheel assembly comprises a second flywheel having a central opening and a second gear portion having a central opening, wherein the second gear portion is adjacent the second flywheel, such that the elongated flywheel axle is inserted through the second flywheel central opening and through the second gear central opening when the device is assembled.
4. The device of claim 1 wherein the first yo-yo body half contains at least two slots formed in the rim of the first yo-yo body half.
5. The device of claim 1 wherein the second yo-yo body half contains at least two slots formed in the rim of the second yo-yo body half.
6. The device of claim 1 wherein the top component comprises a first removable cover element for coupling to the exterior side of the first yo-yo body half, and a second removable cover element for coupling to the exterior side of the second yo-yo body half.
7. The device of claim 6 wherein the first cover element contains at least two slots formed in first cover element.
8. The device of claim 6 wherein the second cover element contains at least two slots formed in second cover element.
9. The device of claim 1 wherein the top component comprises a tip portion that may be coupled to one or both of the yo-yo body halves.
