Abstract
In an oscillating fin propulsion apparatus operatively connected to a scuba diver moving on or through a body of water, a propulsive force may be produced by a pair of fins adapted to sweep back and forth in a generally transverse direction relative to the longitudinal axis of the scuba diver's body. The fins may be mounted on opposite sides of a frame detachably secured to a scuba tank. The fins may be rotatable in an oscillatory motion about respective axes coplanar to the center longitudinal axis of the frame. Drive members operable by the scuba diver may be operatively connected to the fins. The oscillating fins may provide a propulsive force to propel the scuba diver longitudinally forward during both oscillating directions of the fins as they sweep back and forth.
Claims9
A water propulsion apparatus, comprising:
- a) a clamp frame, said clamp frame including a left portion, an intermediate portion and a right portion, said left portion and said right portion extending generally laterally outward from respective opposite lateral sides of said intermediate portion;
- b) a left fin and a right fin rotatably secured to a respective said left portion and said right portion of said frame;
- c) a left drive handle and a right drive handle operatively connected to a respective said left fin and said right fin;
- d) a shaft bearing fixedly secured to a distal end of each said left portion and said right portion of said clamp frame;
- and
- e) wherein said left fin and said right fin are fixedly connected to a respective fin base rotatably connected to respective said left portion and said right portion of said clamp frame, wherein movement of said left drive handle and said right drive handle in a reciprocating motion generally transmits a torque force for oscillating said left fin and right fin transverse to the a center longitudinal axis of said clamp frame.
