Abstract: A splash guard for a snorkel tube has an extension pipe, a pivot member pivotally mounted on the extension pipe, a space surrounded by the extension pipe and the pivot member, a float member pivotally mounted on the pivot member and located in the space, a closure member disposed on the pivot member, and a cover disposed on the extension pipe. The extension pipe has a first aperture and a second aperture in opposition. The pivot member has two pivot arms and a support portion. A pivoting limit is formed in a surface of the support portion facing the extension pipe which is selectively abutted by the float member. The closure member selectively seals the first aperture. The cover has a socket selectively engaged by the projection. The present invention can prevent inadequate sealing and has the advantages of light weight and small volume.

Abstract: A splash guard comprises a housing comprising a first aperture, a pivotal member comprising a pivot aim pivotally connected with the housing and a loading part connected with the pivot arm, a space surrounded by the pivot arm, the loading part, and the housing, a float member pivotally connected with the loading part and positioned in the space, and a closure member mounted on the first mounting portion and selectively covering the first aperture. The loading part has a side surface facing the housing and a pushing portion positioned on the side surface. The float member selectively abuts the pushing portion. The direction in which the float member pivots about the pivotal member and the direction in which the pivotal member pivots about the housing are reverse to each other. The splash guard is convenient in use and storage and provides safety and comfort to the snorkeler.

Abstract: A diving mask has a mask portion and a skirt mounted securely to the mask portion. The skirt has an opening with a contact surface and has at least two pads. The contact surface of the opening fits and covers a diver's eyes to prevent water from permeating the mask, when worn. The pads are made of soft and resilient material, are attached to the contact surface of the opening of the skirt and respectively correspond to corners of the diver's eyes. Each pad may be an arch and defines a gap between the pad and the contact surface so when a diver wears the diving mask, the pads closely abut around the corners of the diver's eyes to avoid the corners being pressed. Therefore, the diving mask is ensures a diver experiences normal eyesight and comfort for improved safety.

Abstract: A snorkel connector has a base tube, a mounting tube and a mouthpiece. The base tube has two outer side walls and two side recesses. The side recesses are respectively formed in the outer side walls and each have a bottom and a bottom recess. The bottom recesses are formed respectively in the bottoms of the side recesses. The mounting tube is removably mounted on the base tube and has two wings and a supporting part. The wings are formed on the mounting tube, are held in the side recesses of the base tube and have protrusions. The protrusions are formed on the wings of the mounting tube and engage the bottom recesses of the base tube to hold the mounting tuber onto the base tube. The mouthpiece is mounted on the mounting tube and allows the support part of the mounting tube to extend into.

Abstract: Protective lenses with a flexible gasket assembly has a main lens, at least one peripheral lens, at least one hinge, a main lens gasket and at least one peripheral lens frame. Each hinge bonds to the main lens and one of the at least one peripheral lens to connect the main lens and the peripheral lens and provides a resilient cushion between the main lens and the peripheral lens to keep the lenses from breaking. The main lens gasket and the peripheral lens gasket are able to compensate for inaccuracies in the lenses prevent sharp edges on the lenses from injuring people.

Abstract: A valve for a snorkel has a body, a floating cylinder and a seat. The body has a floating cylinder chamber. The floating cylinder chamber is formed inside the body and has a top opening, a bottom and a tracking extension. The tracking extension is formed at the bottom of the floating chamber. The floating cylinder is slidably mounted inside the floating cylinder chamber and has a bottom and a channel. The channel is formed at bottom of the floating cylinder and receives the tracking extension of the floating cylinder chamber to guide the floating cylinder toward to certain direction. The seat is mounted at the top opening of the floating cylinder chamber and has a cushion. The cushion is bellows-shaped and is mounted on the seat. When the cushion abuts against the floating cylinder, the cushion is adjustable at angle to seal tightly the floating cylinder chamber.

Abstract: A method for making a lens retainer for a dive mask has multiple steps comprising preparing a frame, mounting a mold on the frame, filling the mold with liquid plastic, curing the liquid plastic and removing the mold from the frame. A first step is preparing a frame having at least one opening and multiple interface holes. The at least one opening is formed through the frame. The holes are formed through the frame. A second step is mounting a mold on the frame. Then the mold and the interface holes are filled with liquid plastic to form a crown on the frame. The plastic is cured, and the mold is removed from the frame. The plastic in the interface holes form multiple rods that hold the crown on the frame.

Abstract: A mask strap adjuster attaches a strap with right triangular ribs to a mask, allows the strap to be tightened by pulling the strap and comprises a base, a cover and a connector. The base has two corresponding moveable caps. Each cap has two nubs. The cover is mounted on the base and has a pawl and two nubs. The pawl engages the ribs on the strap to allow the strap to be tightened by simply pulling the strap. The nubs of the cover are pressed selectively by the nubs on the caps and press the cover away from the base and the pawl away from the ribs to loosen the strap. The cover and the base can be short.

Abstract: A waterproof device for a snorkel is mounted on a distal end of a breather pipe and has a lower shell, a ring, an upper tube with an open end, an elastic collar, and an upper shell. A lower pipe is mounted to a lower end of the lower shell and the ring is received into the lower pipe. The upper tube is pivotally connected to the ring via the elastic collar securely mounted between the ring and the upper tube. A seal board is mounted in an inner wall of the upper shell thereby achieving a water proof effect when the open end is securely connected to the seal board.

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 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 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: A structural improvement of a diving mask which consists of a main frame, a sub-frame, a lens and a skirt. Tenons are provided on the sub-frame, engaging mortises on the lens. A soft connecting edge is provided on the skirt, which is closely connected with a periphery of the lens. A rigid structure is established by the tenon jointing the sub-frame with the lens, and the connecting frame of the skirt is closely connected with periphery of the lens, when the main frame is connected with sub-frame. This construction allows the diving mask lens removal and keeps a stable connecting state after its assembly.
