Abstract
A self-propelled spinning device having a first and second hemisphere connected together to form a hollow housing. A drive system is disposed in the hollow housing and a plurality of projections extends outward from the first or second hemisphere. The drive system includes an eccentric path of rotation causing the hollow housing to spin about a rotational axis. The projections propel the self-propelled spinning device in a forward direction.
Claims17
A self-propelled spinning device, comprising:
- a hollow housing comprising:
- a first hemisphere;
- and
- a second hemisphere connected to the first hemisphere;
- a drive system rotatably mounted about a rotational axle disposed in the hollow housing, the drive system having an eccentric path of rotation about the rotational axle;
- and
- a plurality of fins extending radially outwards from a partially spherical cap removably attached to the first hemisphere, wherein the eccentric path of the drive system rotates the hollow housing, which in turn rotates the fins that are statically fixed adjacent to an apex of the partially spherical cap attached to the hollow housing, propelling the hollow housing in a forward direction with eccentric rotation opposite of the fins through a liquid.

A self-propelled spinning device, comprising:
- a hollow housing comprising:
- a first hemisphere;
- and
- a second hemisphere connected to the first hemisphere;
- a drive system rotatably mounted about a rotational axle disposed in the hollow housing, the drive system having an eccentric path of rotation about the rotational axle, the eccentric path of rotation being caused by a weight attached to the drive system that is pulled by gravitational forces causing the hollow housing to eccentrically spin;
- and
- a plurality of projections extending radially outwards from a partially spherical cap removably attached to the first hemisphere, wherein the eccentric path of the drive system rotates the hollow housing, which in turn rotates the projections that are statically fixed adjacent to an apex of the partially spherical cap attached to the hollow housing, propelling the hollow housing in a forward direction with eccentric rotation opposite of the projections through a liquid.

- and
- a seal disposed between the first hemisphere connected to the second hemisphere;
- a drive system rotatably mounted about a rotational axle disposed in the hollow housing, the drive system having an eccentric path of rotation about the rotational axle;
- a weight attached to the drive system, wherein the weight is pulled by gravitational forces causing the hollow housing to spin;
- and
- a plurality of projections extending radially outwards from a partially spherical cap removably attached to the first hemisphere, wherein the eccentric path of the drive system rotates the hollow housing, which in turn rotates the projections that are statically fixed adjacent to an apex of the partially spherical cap attached to the hollow housing, propelling the hollow housing in a forward direction with eccentric rotation opposite of the projections through a liquid.
