Abstract: A wet suit for scuba divers comprising a front portion (2) in the form of two flaps (2a, 2b) that can be opened to permit the suit being put on. The flaps are connected to each other by means of a zip fastener (3). The front portion (2) has associated with it an elastic and impermeable diaphragm (9) that extends in a position corresponding to the front portion (2) and will come to be interposed between the front portion and the diver's body when the suit is worn.

Abstract: A device for operating the inflation and deflation valves of the air chamber of a scuba diver's balancing jacket (10) provided with inflation and deflation valves and means (31, 34) for operating these valves that can be controlled by the diver and comprising a handgrip (30) forwardly projecting from a side position on the lower edge of the jacket, said operating means of said inflation and deflation vales being situated on said handgrip.

Abstract: A buoyancy compensator jacket comprising at least one air chamber (3) associated to a back portion (2) of the jacket and a couple of quick-release valves (6, 7), arranged on an outer face (2a) of said back portion (2), respectively near the upper and lower edges (2b, 2c) thereof. Respective ropes (8, 9) extend from the valves (6, 7) for the operation thereof. A supplementary operation rope (11) extends from the lower valve (7), the supplementary rope (11) of the lower valve (7) and the rope (8) of said upper valve (6) being mutually connected at least in correspondence to the free ends, whereby the air chamber (3) can be deflated through both valves (6, 7) by means of a single action.

Abstract: Swimming goggles comprising a rigid frame (2) for supporting a pair of glass-shaped transparent members (1), each formed by a flat lens (1a) and a flanged bush (1b) for the connection to the frame, the bush being made of a mouldable thermoplastic material. The flat lenses are made of a plastic material different from that of the bushes and having a softening temperature higher than that of the material of the bushes and no-mist and/or no-scratch properties. The lenses are perimetrically fixed to the bushes within grooves (6) formed on the respective bushes.

Abstract: A dive mask comprising a rigid frame (1) for supporting transparent glasses (3), and a flexible seal (5) extending from the contour of the frame (1) and fit to be secured on the diver's face by means of an adjustable strap. The glasses (3) are supported by the frame (1) so as to have a downward inclination with respect to the orthogonal plane of the visual axis (X) of the diver when the mask is put on. In the dive mask, the ratio between the height of the glasses (3), measured orthogonally to the axis of view (X) when the mask is put on, and the maximum distance between the axis of symmetry of the frame (1) and the edge of each glass (3) is greater than or equal to 0.75. The view of the upper chest portion of the diver is made possible.

Abstract: A swimming fin comprising a blade (1) in a relatively stiff material extending from a shoe (7) of incomplete development at the rear in a relatively soft material and a strap (6) of adjustable length connected to the shoe for wrapping at the rear the foot of the swimmer. From the rear side of the blade there extends a concave sole (2), the shoe (7) being connected to the top face thereof, and to the sides thereof flaps (4) extend to which the ends of the strap (6) are connected. The swimming fin further comprises a longitudinal strip (11), in a material of intermediate stiffness between that of the blade and that of the shoe, extending along the top face of the blade (1) and above the shoe (7) to connect the blade and the shoe therebetween.

Abstract: A device for regulating the length of a swimming goggles strap (5), said goggles comprising a pair of supporting frames (1) providing a couple of parallel fins (3) radially extending from the outer side of each frame, the free ends of each couple of the fins being joined by a respective pivot (4), strap (5) wrapping around each pivot and having a plurality of transverse stop-ribs (7). The device comprises a respective stop lever (9) and a tooth (8) extending from it, engageable with one of ribs (7), said stop lever comprising a first arm (11), having a first end pivotally connected to fins (3) and a second end abutting against said frame, and a second arm (10), from the substantially intermediate section of which said tooth transversely extends, said second arm having a free first end for operating and a second end which is integral to the second end of said first arm.

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.
