Abstract: A swimming fin includes a foot pack and a blade. The foot pack has a space therein for being inserted with a sole of a wearer. The blade extends from the foot pack with a flat shape. It is characterized in that a root, which is disposed at an intersection of the foot pack and the blade, is formed by way of alternate arrangement of at lest a hard coil and at least a soft coil.

Abstract: A buckle structure for a swimming mask having a soft mask body, at least one lens, a buckle and a strap. The mask body and lens are integrally combined. The buckle is connected to the mask body by a plurality of pins, which reduces the deformation of the mask body due to the bearing strength of the buckle.

Abstract: A snorkel fixture of swimming mask, it provides a function that allows the user to easily separate the snorkel and the mask, a concaving buckle with a round hole is placed on the snorkel, also an attaching and releasing structure is build to slide into the hole on the concaving buckle to attach on the snorkel. By the chain reaction between the embodiment and allow the buckle to contract, the user can remove the buckle body. The snorkel and the mask can be easily attached and released.

Abstract: A diving mask having a framing apparatus provided on both sides of a nose portion with at least front glasses mounted in front frame; and a mask apparatus made of a soft and flexible material. The mask apparatus includes a nose portion and an edging piece extending with the facial shape, on both sides of nose portion under the front frame, integrally forming lower frames and each frame having a lower lens.

Abstract: An improvement of buckle of swimming mask, said swimming mask comprising a soft mask body, at least a lens, buckle and strap; said mask body and lens are combined integral; the buckle are provided to the mask body in larger area which enable the mask body not easy to misshape which the buckle bearing the strength.

Abstract: A new buckle structure on the two sides of a diving mask, these buckles are used to connect to the strap; the structure includes a frame on each side of the mask frame, a setting hole on the frame, a holder fixed and a fixed cover of the setting hole, a button on fixed cover, the strap goes between holder and a roller, the stopper on the button allows the users to adjust the strap; the structures allows the users to lose the strap by pressing down the button, also the strap can rotate within a small angle due to the holder structures.

Abstract: A diving mask which comprising: A framing apparatus, provided in both sides of nose portion, at least giving front glasses mounted in front frame; A mask apparatus which made by soft and flexible material, having a nose portion and edging piece extending along the facial shape, on the both side of nose portion under the front frame, integrally forming lower frames and each frame providing a lower glasses.

Abstract: A semi-frameless mask; its structure contains a hard glass lens, and a soft flexible skirt; Longer distance buckles are implemented at the sides of the intersection of the lens and the skirt, and the strap is implemented on the buckles. By implementing the longer distance buckles close to the hard lens on the skirt, the forces apply can be averagely spread on the mask while pulling or pushing the strap.

Abstract: The present invention relates to a water preventing equipment fo a snorkel, that attaches to the end of a snorkel, which includes an embodiment and a cover. The embodiment contains a first room and a second room, which is divided by a baffle. The first room connects to the conduit. The cover is located above the end opening and it is an active structure that can flip up and down. The cover covers the end opening and is located above the first room. By using this active cover, this equipment can easily prevent large amounts of water from splashing into the conduit, and can still remain the smoothness of the airway for exhaling water and exhausting air.
