Abstract: A method for the production of a flipper for swimming by injection molding that provides for the production first, of the fin (1) with one flat bent end (1a), then the molding on it of an intermediate element (2) comprising a substantially flat part (2a) overlapping the bent end and from which develop a substantially arcuate part (2b) over it and a forked part (2c) forming two ribs (3), each of which is located both above and below the fin along its lateral edges. Finally, a shoe (5) is molded onto said intermediate element which lines the internal faces of the flat part and the arcuate part.

Abstract: The invention refers to a swimming flipper of the type with a "shoe" part (10) made of relatively soft material and a blade part (20), made of relatively stiffer material, suitably joined to one another and preferably formed with the first part on top of the second. According to this invention, the blade (20) has an outer sole (22) which extends right under the heel (11) of the shoe (10). Furthermore, the blade (10) is equipped with an arched strap (23) which surrounds the upper (13) of the shoe transversally (FIG. 6).

Abstract: An improved diving mask includes a rubber body configured to mate with the user's face, a viewing lens having a mounting frame extending about and secured to its rim and a fairing body which substantially encompasses the rubber body and is configured for snap-fit engagement with the mounting frame with the forward edge of the rubber body sealingly engaged between the fairing body and mounting frame. The assembly is designed to maximize the visual field and means are also provided for quick and regulatable connection with a rear holding-strap.
