Protective eyewear comprising a pair of eye pieces, each defining one of two opposing inner lateral surfaces spaced by a nose bridge. At least one of the inner lateral surfaces comprises a slot for slidably and releasably engaging a locating rib provided on said nose bridge. Said slot comprises a slot locking element and said nose bridge comprises a nose bridge locking element. In a use configuration with the locating rib of the nose bridge engaged within the slot, the slot locking element and the nose bridge locking element cooperate within said slot to releasably secure the locating rib within the slot.

A swim goggles (1) with a spacing adjuster, comprising a left and right eyepiece (2) retained in a frame (4), and an adjustment means (6) for adjusting the spacing (7) between the left and right eyepieces (2) composed of a rotating element (16), which is located between two connecting pieces (5), such that it can be adjusted, and is connected at each end with two opposing threaded connections (18, 19; 20, 21) to the connecting pieces (5), wherein the connecting pieces (5) have a twisting safeguard (8, 8a, 34) that prevents a twisting of the connecting pieces (5) counter to one another in the frame (4).

Methods for providing swimmers with performance metrics, turn detection, and stroke rate detection are disclosed. An example method comprises mounting a wearable device comprising an accelerometer, gyroscope and processor on a swimmer's head, continuously measuring acceleration using said accelerometer and angular velocity using said gyroscope to provide acceleration and angular velocity signals to said processor, processing said acceleration and angular velocity signals to determine first roll and pitch angles, applying a correction to axes of said gyroscope based on said roll and pitch angles to determine corrected angular velocity signals, initializing a heading angle at a pre-defined, non-zero value, integrating said corrected angular velocity signals over a time window to determine changes to the heading angle, determining maximum and minimum heading angles within the time window, and, recording a turn when a difference between the maximum and minimum heading angles within the time window is at least approximately 180 degrees.

The present invention provides a strap adjustment device for connecting with a body of a mask. The strap adjustment device comprises a female element, an elastic strap, and a regulating device. The female element is disposed on one side of the body of the mask and has an opening and a slot. The elastic strap has a male element and an adjusting end portion, which is opposite to the male element. The male element has a shape which is substantially corresponding to the female element. The regulating device is connected to the adjusting end portion. When the strap adjustment device is assembled with the body of the mask, the adjusting end portion passes through the opening and the slot before passing through the regulating device in an adjustable manner and being engaged in place by the regulating device. The male element is located in and positioned in the opening.

Disclosed are foldable swimming goggles. The swimming goggles include a left frame body and a right frame body, wherein the left frame body is provided with a supporting block and a limiting block, the supporting block is internally provided with an accommodating groove, a pressing shaft is clamped in the accommodating groove, the lower portion of the pressing shaft is fixedly provided with a positioning rotary wheel, and the right frame body is provided with a steering block. Firm connection of the product is completed through the pressing shaft and the positioning rotary wheel. When the swimming goggles need to be folded, the pressing shaft is pressed to separate the positioning rotary wheel from the steering block, so that the right frame body rotates to make the product folded.

The present invention relates to a floatable breathing device. The floatable breathing device provides includes a head unit, a snorkel, a plurality of receiving passageways, and an internal pathway. The head unit has buoyant properties and includes an ornamental shaped buoyant outer material and an inner shell positioned within the buoyant outer material. The inner shell forms a head receiving section and a protruding section. The head receiving section is received internal to the buoyant outer material and is configured to be contoured to a human head, the protruding section extending from the head receiving section to a vent opening in the outer buoyant material. The snorkel is connected to and extending through the head unit, while the plurality of receiving passageways are disposed about the inner shell and receiving the snorkel such that the snorkel extends through and exits a portion of the head unit at the vent opening. The internal pathway is positioned along a base of the outer buoyant material and extends between the internal shell and the buoyant outer material, passing to the interior of the interior shell through a cutout in a protruding portion thereof and terminating adjacent to the vent opening.

The present invention relates to water goggles, and particularly relates to water goggles having an excellent waterproofing effect, including a rim, a lens sealedly arranged on the rim, an elastic waterproofing ring sealedly arranged on an inside edge of the rim, and a head band whereof two ends are separately connected to the elastic waterproofing ring. The flexible waterproofing ring includes a first connection part connected to the rim, a support part connected to the first connection part, a left-eye contact part connected to the support part and pressed against the rim of a person's left eye, and a right-eye contact part connected to the support part and pressed against the rim of a person's right eye. The left side of the head band is connected to the left-eye contact part, and the right side of the head band is connected to the right-eye contact part.
