Protective enclosure for electronic device
View Patent ↗A protective cover for an electronic device that has an interactive control panel includes a protective shell having a first member and a second member. The second member is configured to join with the first case. An aperture defined by the protective shell aligns with the interactive control panel. A protective membrane for an electronic device includes a sheet of engineered thermoplastic having dimensions corresponding to features of a surface of the electronic device, and has a combination of sufficient thinness and a dielectric constant that together permit capacitive inputs on a front side of the protective membrane to be transmitted to the capacitance sensing interactive control panel. The protective cover and/or the protective membrane include a metalized coating or metallic additive.
1. A protective cover for an electronic device having an interactive control panel, the protective cover comprising:
a protective shell that is crush resistant and has an inner surface and an outer surface, the protective shell formed to at least partially cover the electronic device when the electronic device is disposed in the shell, the electronic device being a separate unit from the protective enclosure;
an aperture defined by the protective shell, the aperture being aligned to expose at least the interactive control panel when the electronic device is at least partially covered by the protective shell; and
a metallized coating provided to at least part of the protective shell.
2. The protective cover in accordance with claim 1 , wherein the metallized coating includes metal flakes.
3. The protective cover in accordance with claim 1 , wherein the metallized coating is provided to at least the outer surface of the protective shell.
4. The protective cover in accordance with claim 1 , wherein the metallized coating includes an additive.
5. The protective cover in accordance with claim 1 , wherein at least a portion of the protective shell is formed of a rigid plastic.
6. A protective cover for an electronic device having an interactive control panel, the protective cover comprising:
a protective shell having an inner surface and an outer surface, the protective shell formed to at least partially cover the electronic device when the electronic device is disposed in the shell, the electronic device being a separate unit from the protective enclosure;
an aperture defined by the protective shell, the aperture being aligned to expose at least the interactive control panel when the electronic device is at least partially covered by the protective shell; and
a metallic additive provided to at least part of the protective cover.
7. The protective cover in accordance with claim 6 , wherein the metallic additive includes metal flakes.
8. The protective cover in accordance with claim 6 , wherein the metallic additive is a metal coil provided to the protective shell.
9. The protective cover in accordance with claim 6 , wherein at least a portion of the protective shell is formed of a rigid plastic.
10. A protective membrane to be disposed over a capacitance-sensing panel of an electronic device, the protective membrane comprising:
a sheet of engineered thermoplastic selected from a group consisting of thermoplastic polycarbonate, thermoplastic polypropylene, thermoplastic acrylonitrile-butadiene-styrene and thermoplastic compositions containing one or more thereof, the sheet formed in a shape corresponding with features of a front surface of the electronic device including the capacitance sending interactive control panel, the sheet of engineered thermoplastic having a combination of sufficient thinness and a dielectric constant that together allow capacitive inputs on a front side of the protective membrane to be transmitted to the capacitance-sensing interactive control panel through the protective membrane; wherein the protective membrane is configured for use with a protective cover for the electronic device, the protective cover comprising:
a protective shell that is crush resistant and has an inner surface and an outer surface, the protective shell formed to at least partially cover the electronic device when the electronic device is disposed in the shell, the electronic device being a separate unit from the protective enclosure; and
an aperture defined by the protective shell, the aperture being aligned to expose at least the interactive control panel when the electronic device is at least partially covered by the protective shell.
11. The protective membrane according to claim 10 , wherein the protective membrane has a dielectric constant in the range of 2.2 to 3.8.
12. The protective membrane according to claim 10 , wherein the protective membrane has a thickness in the range of 0.003 inches to 0.020 inches.
13. The protective membrane according to claim 10 , wherein the protective membrane has matte texture, said texture having a texture depth of 0.0004 to 0.003 inches that reduces the surface area of said protective membrane that is in frictional contact with a user's finger and permits said user's finger to glide smoothly upon the surface of the membrane without sticking.
14. The protective membrane in accordance with claim 10 , further including a chemically resistant additive provided to at least part of the membrane enclosure to impart chemical resistance to the protective membrane.
15. The protective membrane in accordance with claim 14 , wherein the chemically resistant additive includes metal flakes.
16. The protective membrane in accordance with claim 14 , wherein the chemically resistant additive includes a metallized coating.
17. A protective membrane for placement on an electronic device having an interactive control panel, the protective membrane comprising:
a sheet of engineered thermoplastic having perimeter dimensions corresponding to features of at least one surface of the electronic device, and configured to be disposed over and adjacent to at least the interactive control panel of the electronic device, the protective membrane being sufficiently thin to allow inputs on a front side of the protective membrane to be received by the interactive control panel; and
a metallized coating provided to at least part of the sheet; wherein the protective membrane is configured for use with a protective cover for the electronic device, the protective cover comprising:
a protective shell having an inner surface and an outer surface, the protective shell formed to at least partially cover the electronic device when the electronic device is disposed in the shell, the electronic device being a separate unit from the protective enclosure; and
an aperture defined by the protective shell, the aperture being aligned to expose at least the interactive control panel when the electronic device is at least partially covered by the protective shell.
18. The protective membrane in accordance with claim 17 , wherein the metallized coating includes metal flakes.
19. The protective membrane in accordance with claim 17 , wherein the metallized coating includes a metal-based additive.
20. The protective cover in accordance with claim 4 , wherein the additive includes metal flakes.
