Abstract

A computer system may comprise an upper housing, a processor, a display screen, a keyboard case, and a lower housing. The display screen may be attached to the upper housing. The processor may be disposed within the upper housing. The lower housing may comprise a keyboard and may be mounted to and pivotable with respect to the upper housing. The keyboard cover may be adapted to cover the keyboard.

Claims

1. A computer system comprising:

an upper housing;

a processor within the upper housing;

a display screen attached to the upper housing;

a lower housing comprising a keyboard, the lower housing being mounted to and pivotable with respect to the upper housing; and

a keyboard cover being mounted on an upper housing surface opposite of the display screen wherein the keyboard cover moves pivotably relative to the display screen.

2. The computer system of claim 1, wherein the upper housing surface opposite of the display screen has a recess for receiving and nesting the lower housing case.

3. The computer system of claim 1, wherein the keyboard cover has a hinge structure.

4. The computer system of claim 3, wherein the hinge structure is mounted transversely across the upper housing surface opposite of the display screen.

5. The computer system of claim 3, wherein the keyboard cover is adapted to move pivotally on the hinge.

6. The computer system of claim 1, wherein the keyboard cover further comprises a biasing element for generating a biasing force to damp pivoting force due to gravity.

7. The computer system of claim 1, wherein the upper housing surface opposite of the display screen has a recess for receiving and nesting the keyboard cover.

8. The computer system of claim 1, wherein the cover is adapted to act as an easel to support the upper housing.

9. The computer system of claim 1, wherein the keyboard case further comprises a hinge whereby the keyboard case is mounted to an edge of the upper housing.

10. The computer system of claim 1, wherein the keyboard and the keyboard cover form a latch key assembly wherein the keyboard cover locks the keyboard so as to maintain the keyboard at an angle with the upper housing.

11. An electronic computing device comprising:

an upper housing having a front face and an opposing rear face;

a processor within the upper housing;

a screen attached to the upper housing at the front face, the screen is coupled to be operable by the processor to display data to a user of the device; and

a lower housing having a hinge and a keyboard, wherein the lower housing is adapted to be received and nested in a recess on the rear face of the upper housing.

12. The electronic computing apparatus of claim 11, wherein the lower housing pivots over substantially 120 degrees with respect to the upper housing.

13. The electronic computing apparatus of claim 11, wherein the screen is a touch screen.

14. The electronic computing apparatus of claim 11, wherein the lower housing has a biasing element for generating a biasing force to damp pivoting force due to gravity.

15. The electronic computing apparatus of claim 11, wherein the lower housing and the upper housing have an angle stopper mechanism wherein the keyboard is urged to maintain a certain angle with the upper housing.

16. A mobile computing device comprising:

an upper housing having a screen carried on a first side;

a lower housing having a set of input keys disposed on an operational surface, the lower housing being operably coupled to the upper housing for movement between a slate mode and a desktop mode, wherein, in the slate mode, the lower housing folds into a surface of the upper housing opposite of the first side with the set of input keys facing away from the first side of the upper housing.

17. The mobile computing device of claim 16, wherein in the desktop mode, the lower housing is unfolded with the set of input keys facing upward.

18. The mobile computing device of claim 17, wherein in the desktop mode, the lower housing forms an angle with the upper housing.

19. The mobile computing device of claim 16, further comprising a laptop mode wherein, in the laptop mode, the lower housing is unfolded and is substantially parallel and adjacent to the upper housing.

20. The mobile computing device of claim 16, further comprising a keyboard cover being mounted on the upper housing surface opposite of the first side.
