Vibration-powered floating object

摘要

A vibration-powered device adapted for flotation and propulsion on an upper surface in a liquid. The device having a body with a top side adapted to be at least partially disposed above the surface of the liquid, and a bottom side adapted to be at least partially submerged below the surface of the liquid. A vibration mechanism is disposed in the body. A propulsion fin is connected to the body. The fin includes a top side adapted to be disposed at least partially above the liquid surface, a bottom side adapted to be disposed at least partially below the surface. The vibration mechanism is adapted to oscillate the free distal end of the propulsion fin upward and downward.

1. A vibration-powered device adapted for flotation and propulsion on an upper surface in a liquid, said device comprising:
a body having an internal water-resistant cavity and an external surface, the body further having a longitudinal axis, a front end portion and a rear end portion, a top side and a bottom side, a vibration mechanism disposed with the internal water resistant cavity and the vibration mechanism having a rotational motor adapted to rotate an eccentric load; a propulsion fin, said fin having a proximal end connected to the body, said fin having a free distal end opposite the proximal end, said fin having a top side adapted to be disposed at least partially above the surface of the liquid, said fin having a bottom side adapted to be disposed at least partially below the surface of the liquid; wherein said vibration mechanism when actuated is configured to oscillate the free distal end of the propulsion fin upward and downward; and a flotation member, the flotation member having a recess configured to directly secure over a portion of the external surface of the body, the flotation member having a shape configured to substantially maintain a portion of the top side of the body above the surface of the liquid and further configured to substantially maintain a portion of the bottom side of the body below the surface of the liquid when the flotation member is secured over the portion of the external surface of the body.
