| 摘要 |
<p>The invention relates to a swimming device with manual, pneumatic, hydraulic or electromechanical actuation intended for immersed or semi-immersed motion of humans. According to the invention, the device may have several embodiments with two or more propelling elements (), of the following types: with the prevalent dimension parallel to the attachment axis, with surfaces which are hydrodynamically profiled, axially flexible or elastic (V-shaped flexible wing, V-shaped tail); with the prevalent dimension perpendicular to the attachment axis(V-shaped flexible axial wing; transverse wing), with some mechanisms () for converting the reciprocating translation motion into multiplied oscillating motion or unitary, frontal or axial, mounted on a flat-type body () which is either held in the swimmer's hands or mounted at the user's back, being driven either by hand, through a drive mechanism () which uses the feet pushing force, by cable, or pneumatically, hydraulically, electromechanically, for the immersed or semi-immersed motion of humans.</p> |
