Protective case for a computing device

1. A composite case for a computing device, comprising:

a first portion operable to protect and detachably connect to a display portion of the computing device, the first portion having one or more perimetral fasteners disposed on edges of the first portion;

a second portion operable to protect and detachably connect to an input device portion of the computing device, the second portion having one or more perimetral fasteners disposed on edges of the second portion wherein the display and input device portions of the computing device are detachably connected to each other through a multi-pivot hinge unit operable to rotate about one or more computing device axes defined between the display and input device portions to move the computing device between open and closed states;

a hinge cover portion defining a rigid elongate hemispheric chamber for receiving the hinge cover of the computing device and connected to the first portion operable to detachably receive and surround the multi-pivot hinge of the computing device wherein the rigid elongate hemispheric chamber comprises a plurality of bulkheads;

wherein a protective shell is formed between the first and second portions when the first and second portions are joined at the hinge cover portion and one or more perimetral fasteners of the first and second portions opposite the hinge cover portion are secured with each other in a closed position.

2. The case of claim 1 , wherein the first portion further comprises:

a resilient portion dimensioned to detachably receive perimetral edges of the display portion of the computing device; and

a rigid portion detachably connected to a rear surface of the display portion of the computing device, the rigid portion being impact resistant and dimensioned to shield a rear surface of the display portion.

3. The case of claim 2 , wherein one or more impact resistant corners are formed with the perimetral edge and/or the rear surface.

4. The case of claim 1 , wherein the rigid elongate hemispheric chamber extends between lateral edges of the second portion of the case, the rigid elongate hemispheric chamber being operably to axially align with and receive the hinge cover of the computing device;

a gap for moving between open and closed states between the multi-pivot hinge of the computing device to and the chamber when the hinge cover portion is secured to the multi-pivot hinge;

a resilient fastener tab extended from a lower portion of the chamber for connecting the hinge cover portion to a recess on a lower surface of the second portion of the case, the tab extended between opposite lateral edges of the second portion and being substantially planar to the recess on the lower surface of the second portion.

5. The case of claim 4 , the resilient fastener tab comprising:

a first portion substantially surrounding an outer surface of the chamber; and

a second portion pivotally attached to the first portion along an edge axially aligned with the chamber, the second portion being operable to be substantially planar and connected to the recess of the second portion of the case.

6. The case of claim 5 , wherein the first and second portion are formed from a shared outer grip inducing surface.

7. The case of claim 4 , further comprising:

a retention band extended from opposite ends of the chamber, the retention band being operable to securely retain the multi-pivot hinge of the computing device with the chamber.

8. The case of claim 7 , the retention band being movable and/or flexible.

9. The case of claim 4 , wherein the plurality of bulkheads are normal to the longitudinal axis of the rigid elongate hemispheric chamber and extend along the chamber between lateral edges of the second portion; wherein the second portion is substantially rigid and the hinge cover is resilient; and

wherein the recess of the second portion render flexible the rear edge of the second portion.

10. The case of claim 1 , wherein the perimetral fasteners of the first portion include:

a forward edge fastener defined by an inwardly facing lip operable to detachably secures to an upper edge of the display portion opposite the hinge cover portion; and

a plurality of lateral edge fastener tabs that extend downward from opposing lateral edges of the first portion, each lateral edge fastener tab being operable to flex outwardly and securely engage with a corresponding receiver disposed on a lateral edge of the second portion.

11. The case of claim 10 , wherein the corresponding receiver of the second portion extends outwardly from the respective lateral edge of the second portion is capable of being received by a recess of the corresponding lateral edge fastener tab of the first portion;

wherein the lateral edge fastener tab is resilient and the corresponding receiver of the second portion is rigid.

12. The case of claim 1 , wherein an axis of rotation of the hinge cover portion is co-extensive to a hinge axis of the multi-pivot hinge unit; and

wherein the multi-pivot hinge unit is an armadillo hinge assembly.

13. The case of claim 1 , wherein when the first portion is detachably connected to the display portion, the first portion provides impact resistance to the display portion regardless of whether the second portion is detachably connected to the input device portion or the first portion.

14. The case of claim 1 , wherein perimetral edges of the first portion extend away from a rear support surface and terminate in a flexible inwardly extending lip operable to flex outwards and securely retain the display portion of the computing device; and

wherein the lip is thicker than the portion of the perimetral edge extending away from the rear support surface.
