20110197881 | Underwater Breathing Apparatus - An underwater breathing apparatus includes a water resistant enclosure for floating on the surface of a body of water. An air collection header and an air pump for generating a constant flow of breathable air, an air supply line for delivering a flow of the breathable air to a user and a check valve for exhausting used air are also provided. At least one mouth piece connected to one of said supply lines and to a user's mouth together with a solar powered rechargeable battery connected to the air pumps enables the air pump to supply breathable air to the user. A safety flag mounted on the water resistant enclosure and extending upward therefrom indicate the presence of an individual below the surface of the water as does a safety warning light mounted on top of the water resistant enclosure. A fresh air vent tube supplies air to the air pump and prevents water from entering the water resistant enclosure while a jet ski fixed to an underside of said water resistant enclosure and guided by the user is used for moving the water resistant enclosure to a different area. Finally, a tether line connects the user to the jet ski while a retractable hose mechanism automatically reels out air hoses when a diver descends and reels in the air hose when the diver ascends. In the preferred embodiment of the invention a micro-computer contains the data from dive tables and automatically reels in and stops at various steps the air hose. | 08-18-2011 |
