Protective enclosure for personal digital assistant case having integrated back lighted keyboard
First Claim
1. A protective enclosure for an electronic device having an interactive control panel and an alphanumeric keyboard comprising:
- a protective shell that is crush resistant and impact resistant, said electronic device being a separate unit from said protective enclosure, said electronic device being insertable in and removable from said shell by hand;
a first aperture in said shell that is aligned with said interactive control panel when said electronic device is disposed in said protective enclosure;
a first protective membrane integrally fixed to said shell over said first aperture so that said first protective membrane is disposed over said interactive control panel of said electronic device when said electronic device is disposed in said protective enclosure and recessed from an outer surface of said shell, said first protective membrane and said shell forming a protective enclosure for said interactive control panel;
a second aperture in said shell that is aligned with said alphanumeric keyboard when said electronic device is disposed in said protective enclosure; and
a second protective membrane that is formed to the shape of said alphanumeric keyboard and that is integrally fixed to said shell over said second aperture so that said second protective membrane is disposed over said alphanumeric keyboard when said electronic device is disposed in said protective enclosure, said second protective membrane having sufficient flexibility to allow activation of said keyboard through said second protective membrane.

Abstract
There is provided by this invention a protective enclosure for a personal electronic device that is generally comprised of a shell that is capable of enclosing and substantially surrounding the electronic device disposed to make the shell substantially watertight, substantially rigid and substantially crush-resistant. The enclosure has a transparent flexible protective membrane that is integrally fixed on the shell so that the flexible protective membrane is positioned over the touch screen of the electronic device when the electronic device is enclosed in the shell. The flexible protective membrane having a back side that has a substantially planar smooth surface that is adjacent to the touch screen of the electronic device wherein tactile inputs on a front side of the flexible protective membrane are communicated to the touch screen through the transparent flexible protective membrane. The enclosure also has a second transparent flexible protective membrane that is integrally fixed on the shell so that the flexible protective membrane is positioned over an alphanumeric keyboard of the electronic device forming a keyboard in the flexible protective membrane such that the flexible protective membrane has total interface with the enclosed keyboard allowing the user to use the keyboard of the enclosed electronic device through the flexible protective membrane.
