Abstract
A swimmer's aid including a strip to which a plurality of laterally extending finlets are attached with the strip being attachable to one or more portions of a swimmer's leg e.g. his shank or his foot, or both. The fins flex in directions opposite to the kick of a swimmer's legs in a manner similar to a conventional foot fin but their center of effort is located closer to the stronger parts of a swimmer's legs rather than only at their extremities as with conventional foot fins. The invention includes a short downwardly angled foot fin having a permanent but shallow angle of about 15.degree. relative to the plane of the foot to permit walking on dry ground while requiring less effort to use in the water.
Claims14
A swimmer's aid comprising a flexible substantially planar finlet having upper and lower end parts and a latterly extending base having first and second sides and being integral with the upper end part of said finlet, means for releasably fixing said base to a portion of a swimmer's leg with the upper end part of said finlet extending from said base laterally away from said swimmer's leg portion and said lower end part extending freely downwardly from said upper end part and laterally spaced away from said portion of a swimmer's leg, said power end part of said finlet having a free end having flexibility enabling said free end to flex about said base beyond said first and second sides of said base and to either side of the plane of said finlet in response to up and down kicking motion in water of said leg portion, and means for restraining said finlet from flexing in response to said kicking motion in any other direction with respect to said leg portion.
