Method and apparatus for underwater operation of non-waterproof equipment

DETAILED DESCRIPTION What I claim is: 1.
An apparatus for adapting a device for underwater operatin, comprising: a waterproof container for said device fabricated from a flexible material; a collapsible gas container fabricated from a material more rigid than said flexible material but less rigid than the device being protected; a pressurization port means for pressurizing said waterproof container; and means for connecting said collapsible gas container to said pressurization port, said connection means including a gas passage between the interior of said waterproof container and said collapsible gas container.
2.
An apparatus as defined in claim 1, further comprising a safety valve for preventing the pressure within said container from exceeding said container's structural limitations.
3.
An apparatus as defined in claim 2 wherein said safety valve includes a pressure release means for equalizing the pressure within said container and the ambient atmosphere.
4.
An apparatus as defined in claim 1, further comprising a valve means for allowing the one-way passage of gas into said container.
5.
An apparatus as defined in claim 4 wherein said valve is a tire valve.
6.
An apparatus as defined in claim 1, wherein said flexible material forming said collapsible gas container has a resistance to deformation which is less than the pressure required to activate any push-button controls on the protected device.
7.
An apparatus as defined in claim 1, further comprising means for inflating said collapsible gas container.
8.
An apparatus as defined in claim 7 wherein said means for inflating said collapsible gas container comprises a sports ball needle valve and said means for connecting said collapsible gas container to said pressurization port comprises a hollow inflation needle of the type used with sports ball needle valves.
9.
An apparatus as defined in claim 1, comprising a weight means to at least partially offset the buoyancy of said collapsible gas container.
10.
An apparatus as defined in claim 9, wherein said weight means is a dense material contained within said collapsible gas container
