  • Patent number: 9492712
    Abstract: A swimming paddle with an upper rounded swimcap-shaped edge terminating in side indentations that define cap-securing temples, and a central goggle-securing notch cooperating with a concave region in the lower edge to store goggles vertically on the paddle. The paddle may further include fingerpad-indexing holes extending through the body of the paddle from the inner face to the outer face, the holes sized to allow only the fingerpads of a swimmer's extended fingers to partially protrude from the inner face. A method for custom fitting a swimming paddle to a particular swimmer's hand includes generating a side-by-side image of the swimmer's hand and a commonly-carried object such as a mobile phone in a common plane. The image is compared to stored dimensional data for the object to remotely determine the dimensions of the swimmer's hand and manufacture a custom paddle.

  • Patent number: 9248344
    Abstract: This invention is related to an apparatus and method for swimming by use of a swimming aid comprising an anchoring article and handlebars that are rotated side-to-side by the user. The side-to-side rotation of the handlebars causes a vertical tail fin to move laterally through the water, displacing water, and propelling the user in a forward direction. In a preferred embodiment of the present invention, foldable swim fins are attached to the handlebars. These swim fins can rotate about a horizontal axis such that they displace water when the handlebars are rotated in one direction and rotate horizontally 90 degrees to minimize resistance when the handlebars are rotated in the opposite direction.

  • Publication number: 20120009833
    Abstract: Disclosed is a unique concept of a handheld swimming paddle containing a pivoting member with an attached angled section, which provides instant resistive and visual feedback when a swimming stoke is not properly executed. Such feedback allows the unique paddle to act as a technical aid for all levels of swimmers, as well as a device to build the correct muscles required to swim with proper stroke mechanics through constant monitoring. The disclosed invention will introduce resistance that will impede the swimmer's forward progress only when a pull is not properly executed, which means that it will be easier for the swimmer to execute a full proper stroke rather than swim with poor mechanics. Additionally, the disclosed invention will assist in the proper hand placement and orientation at the beginning of the stroke.

When the connected dolphin-tail style swim fin flows through a path of displaced water from the flat swim fin at a proper angle of attack, it produces a lifting force that assists in swimming. The dolphin-tail style swim fin is shaped to enhance the propulsion from the flat swim fin. A swim fin assembly can be integrated with both flat and dolphin-tail style fins as one unit. The dolphin-tail style swim fin is shaped to generate lift as water flows across it and can be used directly by the hand (without a flat fin) or used with a handle that can be attached in lieu of the flat fin.

  • Patent number: 5795201
    Abstract: This one-handed canoe paddle is comprised of a blade portion, a hand grip portion, and an arm cuff portion. The hand grip is integral with the blade and is at an angle to the centerline of the paddle approximating the angle which a closed hand makes with the centerline of the forearm when the hand and forearm are in alignment. The arm cuff is U-shaped, positioned perpendicular to the plane of the paddle, and connected to the paddle by a shaft that is of a piece with the blade portion and offset of the centerline of the paddle. The angled hand grip being integral with the blade, the connecting shaft being offset, and the uniquely positioned arm cuff taken together create an aggregate design which:permits quick, easy access to the paddle;lets the paddle be picked up and used with one hand;provides the leverage necessary to propel the canoe in any direction without changing grip position;allows the wrist to be held in a neutral position during use of the paddle; andproduces an esthetically pleasing unit.
