Abstract
An anti-drowning apparatus configured to inflate a balloon when a swimmer with the apparatus is submerged to an unsafe depth so as to help the swimmer return to the surface. The apparatus may be integrated into a swimming garment. An integrated emergency flotation apparatus may also include a manual pump configured to inflate a compression port used to store compressed air for inflating the balloon.
Claims20
A swimming garment including emergency flotation apparatus, the apparatus comprising:
- a compression port configured to store compressed air;
- an inner tube slidably engaged with an outer tube, each of the inner and outer tubes having respective apertures formed therein, wherein compressed air stored in the compression port is expelled into a flotation balloon when the inner tube apertures and outer tube apertures are aligned;
- a spring disposed between a proximate end of the outer tube and a proximate end of the inner tube to urge the inner tube proximate end away from the outer tube proximate end such that the inner tube apertures and outer tube apertures are not aligned;
- and
- a water pressure responsive mechanism configured to urge the inner tube toward the spring, wherein a water pressure level associated with an unsafe depth is sufficient to cause compression of the spring such that the inner tube aperture and outer tube aperture become aligned such that the flotation balloon is inflated.

Apparatus disposed within a swimming garment to provide emergency flotation thereto, the apparatus comprising:
- a compression port configured to store compressed air;
- an inner tube slidably engaged with an outer tube, each of the inner and outer tubes having respective apertures formed therein, wherein compressed air stored in the compression port is expelled into a flotation balloon when the inner tube apertures and outer tube apertures are aligned;
