The present invention relates to an air injection device. The air injection device includes: a body having an air passage formed therein; and an opening and closing part coupled to one end periphery of the body and having an opening and closing protrusion protruding from an inner surface thereof toward the air passage of the body by a given length in such a manner as to open and close the air passage, wherein the opening and closing protrusion is moved in a first direction toward the body or in a second direction opposite to the first direction by means of a user's control for the opening and closing part, and the movement of the opening and closing protrusion in the first direction or in the second direction is guided by means of a guide groove formed on an outer peripheral surface of one end portion of the body and a guide protrusion formed on the inner peripheral surface of the opening and closing part in such a manner as to be inserted into the guide groove.

A fabric for wetsuits is provided, the fabric having heat retention, stretchability, and quick drying properties. The fabric for wetsuits is formed by bonding a cloth of a weft knitted fabric plait knitted from polypropylene multifilament threads and elastic threads onto one or both surfaces of a sponge sheet made of chloroprene foamed rubber. Furthermore, the elastic threads of this cloth are heat-fused polyurethane elastic fibers, and the elastic threads of the weft knitted fabric are heat fused to each other. Moreover, the elastic threads are heat fused to each other by heat setting at 100 to 140°C.

The invention consists of a safety device that can easily be incorporated into any type of waterproof clothes and work clothes and is designed for protecting people who accidentally fall into the sea, insulation against low water temperatures, as well as a heat source that considerably prolongs survival time in low-temperature water being provided. The invention comprises: a main ring-shaped bag (1), the outermost part of which is provided with a plurality of long, narrow secondary bags (5); and a check valve (3) arranged on the surface of the main bag which contains sodium which, upon contact with water, causes a chemical reaction that seals possible points at which water could enter the clothing and further provides a heat source for the body.

A paddle sport garment (10) is provided, which comprises: a main body portion (12) including at least one buoyancy device; first and second arm portions (14, 16) extending from the main body portion (12); and a spraydeck (30) including a further buoyancy device. The paddle sport garment (10) may further comprise a harness (20) including one or more straps (21-25) arranged to extend around the torso of a wearer of the paddle sport garment (10).
摘要:
A wearable computing device that is secured or attached to a resilient strap, the resilient strap sized to fit around at least a part of a circumference of a human head. The device has a waterproof storage volume housing a plurality of sensors. The wearable computing device may calculate a plurality of swimming metrics based at least partly on data received from the at least one sensor. The wearable computing device may include a wireless communication subsystem secured to the resilient strap within the waterproof storage volume and may transmit at least one of the calculated plurality of swimming metrics to at least one computing device via the wireless communication subsystem. The wearable computing device may include at least one user output component and may present an indication of at least one of the calculated plurality of swimming metrics at the at least one user output component for communication to the user. The indication may be audio played in an ear piece connected to the strap, or may be visually displayed on a display in an eye goggle portion of the strap.
