Abstract
A swimmers paddle wheel (10) that utilizes a crankshaft (20) with a pair of ends (22,24) containing crank arms (28). Each crank arm (28) is out of angular alignment relative to each other, and each crank arm includes a handle grip (46) with a rotating cylinder (48) and a resilient hand grip (50) such that a swimmer may grasp a handle grip (46) with each hand and rotate the crankshaft (20). Floats (52,54) are disposed on each end (22,24) of the crankshaft (20), with the floats (52,54) having a plurality of paddle blades (56) extending outward to provide propulsion when manually rotated within a body of water. A removable swimmer seat (64) is attached to the crankshaft (20) and is used to support a swimmer when stationary in the water or when the paddle blades (56) are rotated.
Claims19
A swimmers paddle wheel comprising:
- a) a crankshaft having a first end with a crank arm, a second end with a crank arm, and a center section in between the crank arms, with each crank arm out of angular alignment relative to each other, and each crank arm having a handle thereon such that a swimmer may grasp a handle with each hand and rotate the crankshaft, wherein said crankshaft first end, second end and center section further comprise a hollow thermoplastic tube having plugs on the tube's open ends to prevent water from entering, thus adding to the buoyancy of the paddle wheel,
- b) a float disposed on each crankshaft end, with said floats having a plurality of paddles extending outward therefrom for propulsion within a body of water when manually rotated, and
- d) a removable swimmer seat attached to said crankshaft for supporting a swimmer.
A swimmers paddle wheel comprising:
- a) a crankshaft having a first end, a second end and a center section with a pair of offset crank arms positioned between the center section and each end, with said crank arms out of alignment relative to each other by being angularly slanted from 40 degrees to 50 degrees to assure optimum balance,
- b) each crank arm having a retained revolving handle grip thereon such that a swimmer may grasp the handle grip with each hand and rotate the crankshaft without changing the balance and hand angle position,
- c) a first wheel float disposed on the crankshaft first end, and a second wheel float disposed on the crankshaft second end, with both floats having a plurality of paddle blades extending outward therefrom in a horizontal transverse pattern for propulsion within a body of water when manually rotated, and
- d) a removable swimmer seat attached to said crankshaft at a midpoint of the center section, said seat for supporting a swimmer.
