Patent

CA 2310574

A pair of swim fins is disclosed with each fin (1) comprising a blade (3) having a first planar surface (x-x) and defined by an elongated front edge (5) terminated by inner (7) and outer (9) corners and a rear portion (13), the front edge (5) and rear portion (13) held in spaced-apart arrangement by a pair of opposed side edges (15) extending therebetween. The rear portion (13) of the blade (3) has formed therein the bottom portion (17) of a foot pocket (19) arranged about a second planar surface (y-y) for partial inserting therein of the foot of the wearer and including an open heel portion and heel strap (49) to retain a foot in the pocket. The second planar surface (y-y) of the pocket is inclined to the outside of the first planar surface (x-x) of the blade (3) to compensate for the natural pronation of the foot.

L'invention concerne une paire de palmes, chaque palme (1) comportant une lame (3) qui présente une première surface plane (x-x), et étant définie par un bord (5) antérieur allongé terminé par des coins intérieur (7) et extérieur (9) et une partie postérieure (13). Le bord antérieur (5) et la partie (13) postérieure sont maintenus de façon espacée par deux bords (15) latéraux opposés s'étendant entre ceux-ci. La partie (13) postérieure de la lame (3) contient, formée dans celle-ci, la partie (17) inférieure d'un logement (19) de pied placé autour d'une deuxième surface (y-y) plane et permettant à un utilisateur d'insérer partiellement un pied, et comprend une partie de talon ouverte et une bride (49) de talon servant à retenir le pied dans le logement. La deuxième surface (y-y) plane du logement est inclinée vers l'extérieur de la première surface (x-x) plane de la lame (3) afin de compenser la pronation naturelle du pied.
