Abstract: The improved snorkel dry top has a fulcrum to which a float member and a diaphragm yoke are attached. The fulcrum has a blocking tab that rests in an aperture in the float member attaching hook when the snorkel is above the surface of the surrounding water. The diaphragm yoke cannot rotate the diaphragm when the blocking tab is in the hook aperture. Therefore, even when tilted, the snorkel remains open allowing free flow of air into the snorkel tube. Another significant improvement is the connection of the float member, diaphragm and yoke to the snorkel top's splashguard mask. This improvement assures that the delicate structures of these components are not exposed to potentially destructive impact forces in the event that the splashguard mask is removed from the snorkel tube.

The invention does not have fragile lenses. Also, its manufacturing processes are simple. Further, it is compact.

Abstract: Provided is a snorkel having a whistler. In one embodiment, the whistler is mounted on a breathing tube. A swimmer wearing the snorkel may seize the whistler by the mouth prior to making a clear, shrill sound by activating the whistler.

Abstract: A splash protector mounted at top of snorkel is disclosed and includes a tube-shaped adapter unit secured to the snorkel and including a passage; a float unit pivotably secured to the adapter unit and including a projected lever and two upper engagement members (e.g., tabs) at two sides of the lever; a closure unit pivotably secured to the adapter unit and including two mating engagement members (e.g., indents) at both sides, and a closure member adapted to close the passage when the lever pivots upward; and a splash guard secured to the adapter unit for receiving both the float and closure units and including windows for fluid communication. The engagement members are adapted to lockingly engage with the mating engagement members for stopping the closure unit from further pivoting upward and thus preventing the passage from being closed by the closure member undesirably.

Abstract: A mask strap retaining clip releasably secured a breathing tube of snorkel to a diver's mask strap. The retaining clip comprises a clip unit with the diver's mask strap passed through and a ring unit put on the breathing tube. The ring unit comprises a mushroomlike projection extended from its peripheral surface. The projection comprises a neck having a width and a length longer than the width. The clip unit comprises large and small holes. The neck can move from the large hole to the small hole when a lengthwise direction the breathing tube is aligned with a channel between the holes such that the breathing tube can be disposed in an operating position by subsequently turning itself. The clip unit has a tab and the ring unit has a dent for lockingly engaging the tab when the neck is disposed in the small hole.

Abstract: A compact, waterproof swim mask having a unitary skirt, a frame, and a clinging device. The unitary skirt has two lenses for covering the eyes and/or the nose of a user, a flexible frame including two eye-shaped frame elements being capable of communicating with each other. Each frame element is bendable to slightly enlarge when an upper portion is pulled away from a lower portion so that the two frame elements communicate through a gap of a separable intermediate portion for mounting the skirt. The frame also has two endpieces for coupling a rear headband therebetween. The clinging device is secured to the separable intermediate portion of the frame by snapping for fastening the whole swim mask.

Abstract: Provided is a swim mask having a member to cover at least the nose. The swim mask further comprises a peripheral skirt formed of elastomeric material. A portion of the skirt between the lenses is thus flexible such that a person wears the swim mask will feel comfort on a portion on top of the nose and between the eyes by buffering pressing of the portion of the skirt between the lenses thereon. The invention can eliminate the discomfort caused by pressing a hard member on the portion on top of the nose and between the eyes. Moreover, the invention can decrease a distance between the lens and the eye so as to increase view of the wearer.

Abstract: A pair of goggles having a main frame including two fitting members, two lenses fitted in the main frame, two hollow side guards, and a band secured to the side guards. Each of the two fitting members being separable at a line extended from an inner edge of a lens opening in the main frame to an outer edge of the main frame and having two latches extending rearwardly from the two fitting members. Inserting the latch into the side guard will fasten the main frame and the side guard together. Pressing and pulling the latch out of the side guard will disengage the main frame from the side guard. Pulling both latches away from each other will separate each of the two fitting members allowing the lens to be changed. Another embodiment includes a flexible second frame. The lenses are fitted in both the flexible second frame and the main frame.
