  • High efficiency swim fin using multiple high aspect ratio hydrodynamic vanes with pliable hinges and rotation limiters
    Patent number: 8926385
    Abstract: Apparatus, devices and methods of multiple high aspect ratio hydrodynamic horizontal ladder oriented vanes with pliable hinges and rotation limiting flexible webs attached between semi-flexible support beams on swim fins. Pivotal rotation of the hydrofoil vanes can be restricted by flexible membranes, between the hydrofoil vanes and the support beams, to provide an optimum angle of attack for the hydrofoil vanes during a swimming stroke. The fins can have at least one pivoting vane region connected to the support beams with a flexible hinge member. The support beams can be fixedly or rotationally attached at one end to a foot pocket. Methods are provided for limiting the rotation of at least one of the pivoting vanes using flexible web members between vanes and the support beams. Methods for increasing lift and decreasing turbulence and drag on hydrofoils or vanes of the swim fins are also included.
