Abstract:
A swimming device operable by a user, comprising:a. a frame having a body potion and an elongated portion, wherein the body portion has a first surface and an opposite second surface, and a first end and an opposite second end, the first surface receiving the upper body of the user, and the elongated portion has a first end associated with the second end of the body portion and an opposite second end defining an axis therebetween, and a channel extending from the first end of the elongated portion to the opposite second end of the elongated portion, and extending away from the second end of the body portion; b. a first housing and a second housing formed between the first surface and the second surface and positioned on each side of the axis of the elongated portion, respectively; c. a main shaft positioned between the first end and the second end of the elongated portion and rotatable about the axis of the elongated portion, the main shaft having a circumference of a size to be complementarily received in the channel of the elongated portion; d. a first pedal and a second pedal positioned on each side of the elongated portion near the second end of the elongated portion, respectively, the first pedal and the second pedal being rotatably coupled to the main shaft for receiving the feet of the user, so that the user may rotate the first pedal and the second pedal; e. a first propeller and a second propeller received in the first housing and the second housing, respectively, each of the first propeller and the second propeller being rotatably coupled to the main shaft, f. a first drive shaft having a first end and an opposite second end, the first drive shaft being mounted between the first propeller and the second propeller and rotatably coupled to the main shaft and the first propeller near the first end and the second propeller near the second end; and g. a second drive shaft having a first end and an opposite second end, the second drive shaft being mounted between the first pedal and the second pedal and rotatably coupled to the main shaft and the first pedal near the first end and the second pedal near the second end, wherein the first propeller and the second propeller are positioned substantially around the center of gravity of the swimming device so as to provide a stable underwater movement when the first propeller and the second propeller rotate, whereby rotation of the first pedal and the second pedal causes rotation of the main shaft, which in turn causes the first propeller and the second propeller to generate thrust for propelling the swimming device in a desired direction.
