<p>A swim fin (20) has articulating wing members (24) articulated by means of clock washers (70) or the like with respect to a foot pocket (22) to provide, among other things, adjustment of pitch and tension of such wing members or other fin blade. A swim fin with articulating wing members may have a foot pocket with a forked end. Articulating wing members may then be attached to the fork stubs (46, 48), there being right and left articulating wing members. Clock washers or the like may serve to provide stable and adjustable means by which the disposition of the individual articulating wing members may be selectably disposed with respect to the foot pocket. Each of the articulating wing members extends away from the foot pocket, there possibly being a gap (60) separating the individual articulating wing members. The ends of the wing members may be flared outwardly. The outermost side of the articulating wing members may also be flared upwardly.</p> |
