Abstract
An aquatic device, such as a paddle board or surfboard, that includes a propulsion device that utilizes paddle wheels positioned on either side of the board, wherein the paddle wheels are driven by foot operated drive mechanism that utilizes elliptical type of pedaling by the user, and further includes hand controlled rudders to control the direction of travel of the device.
Claims19
An aquatic device, comprising:
- an elongated, buoyant paddle board having a top surface, a first and second elongated edge, a front and a rear;
- a propulsion system positioned on the top surface of the paddle board;
- the propulsion system including,
- at least two paddle wheels, with a first paddle wheel positioned proximate the first elongated edge and the second paddle wheel positioned proximate the second elongated edge;
- an axle rotatably connected to the first paddle wheel and the second paddle wheel;
- and
- foot operated drive mechanism rotatably connected to the axle, such that activation of the foot operated drive mechanism by a user cause the axle and first and second paddle wheels to rotate.

An aquatic device, comprising:
- an elongated, buoyant paddle board having a top surface, a first and second elongated edge, a front and a rear;
- a propulsion system including;
- a platform positioned on the top surface of the paddle board;
- an elongated axle having a first end and second end, the axle being rotatably connected to the platform proximate the rear of the platform;
- a first paddle wheel connected to the first end of the axle and a second paddle wheel connected to the second end of the axle such that when the axle rotates, each of the first and second paddle wheels rotate;
- and
- a first foot plank rotatably connected to the axle and a second foot plank rotatably connected to the axle, with each of the first foot plank and the second foot plank operable between at least a first position and a second position, such that the movement of the first foot plank and the second foot plank between the first position and the second position causes the axle and the first and second paddle wheels to rotate.

A propulsion system for an aquatic device, comprising:
- a platform configured to be positioned on a top surface of a buoyant device;
- an elongated axle having a first end and second end, the axle being rotatably connected to the platform proximate the rear of the platform;
- at least one propulsion device connected to a first end of the axle, such that when the axle rotates, the at least one propulsion device rotates, the at least one propulsion device including a paddle wheel, the paddle wheel including a plurality of wedge shaped portions extending radially from the center of the paddle wheel;
- and
- a foot operated drive mechanism rotatably connected to the axle, such that activation of the foot operated drive mechanism by a user causes the axle and the at least one propulsion device to rotate.
