1. A protective enclosure for a touch screen device having a LCD touch screen comprising:

  • a shell that is capable of enclosing and substantially surrounding said touch screen device, said touch screen device being a separate unit from said protective enclosure, said shell being adapted to insert and remove said touch screen device by hand, said shell being made of a rigid plastic that is substantially devoid of soft PVC, thermoplastic elastomers, and thermoplastic polyurethanes, so that said shell is substantially crush-resistant, said shell having an elevated protective rim substantially surrounding a perimeter of said LCD touch screen of said touch screen device so that when said touch screen device is disposed in said enclosure, said LCD touch screen of said touch screen device is recessed with respect to said protective rim of said shell so that said elevated protective rim protects said LCD touch screen from deflection and breakage by contact with an object that is larger than said perimeter of said protective rim. a compressible gasket that is disposed in a perimeter portion of said shell;

    a clamp connected to said shell that clamps said shell in a closed position so as to compress said gasket when said shell is clamped closed providing an enclosure that is submersibly watertight; and

    a flexible protective membrane that is integrally fixed on said shell so that said flexible protective membrane is disposed over said LCD touch screen of said touch screen device when said touch screen device is disposed in said enclosure, said flexible protective membrane having a back side that has a substantially planar smooth surface that is adjacent to said LCD touch screen of said touch screen device when said touch screen device is disposed in said enclosure so that tactile inputs on a front side of said flexible protective membrane are communicated to said LCD touch screen through said flexible protective membrane, said flexible protective membrane being at least partially transparent such that said LCD touch screen is visible through said flexible protective membrane so that said LCD touch screen is capable of displaying and capturing information through said flexible protective membrane.
