ABSTRACT:
A flipper-type swimming propulsion aid assembly for attachment to the feet of a swimmer to increase the swimmer's effective foot area. The swimming aid for each foot includes a collapsible frame of generally isosceles triangular configuration having side frame members of substantially equal length which are pivotally joined through a heel plate at the heel end of the frame and a foldable cross frame member joining the toe ends of the side frame members. The swimming aid also includes a fabric or plastic sheet web component which is placed over the collapsed frame assembly and thereafter the side frame members are separated with the cross frame member opened and extended. The web component is provided with mating attachment straps affixed to the toe end of said web component and positioned to be wrapped about the cross frame member to maintain such member's open and extended orientation. The side frame members have a relatively inflexible portion along the area of the frame and web component which is spanned by the swimmer's foot and a relatively flexible portion extending from the inflexible portion to the toe end of the side frame members whereby the flipper-type swimming propulsion aid assembly displays flutter flexibility in the extended effective fin area of the assembly and thereby added forward propelling force and action through leg flutter kick movements of the swimmer wearing the propulsion aid assembly on each foot.
