Abstract

A handheld computer comprises a generally rectangular housing and a cover movably connected thereto by a hinge assembly. The hinge assembly includes a tubular member or arm that has one end fixedly (non-rotatably) secured to an edge of the cover and an opposite end pivotally coupled to an edge of the cover. The hinge assembly enables the cover to be moved to at least three different positions. The cover provides a different function in each position. A method of reconfiguring an encasement of a handheld computer to provide at least two different functions includes rotating the cover about at least two different axes to move the cover between at least two different positions. The cover provides a different function in each position

Claims

1. A handheld computer, comprising:

a housing; and

a cover movably connected to the housing by a hinge assembly that enables the cover to be moved to at least three different positions, the cover providing a different function in each position.

2. The handheld computer of claim 1, wherein the hinge assembly enables the cover to be moved to a closed position, an open position, and a stand position.

3. The handheld computer of claim 2, wherein the cover in the closed position is configured to protect a display screen, the cover in the open position is configured to overly a rear face of the housing for permitting access to the display screen, and the cover in the stand position forms an outrigger for maintaining the housing in an inclined position when placed on a horizontal surface.

4. The hand held computer of claim 2, wherein the cover has an inner surface that faces the display screen when the cover is in the closed position, the inner surface facing a rear face of the housing when the cover is in the open position.

5. The hand held computer of claim 2, wherein the cover has an inner surface that faces the display screen when the cover is in the closed position, the inner surface abutting a horizontal support surface when the cover is in the stand position.

6. The handheld computer of claim 1, wherein the hinge assembly comprises a ball and socket arrangement.

7. The handheld computer claim 6, wherein the ball and socket arrangement allows the cover to be detached and reattached.

8. The handheld computer of claim 6, wherein the ball and socket arrangement includes a ball connected to the cover and a corresponding socket formed in an edge of the housing.

9. The handheld computer of claim 8, further including a pair of pads located within the socket on opposite sides of the ball and biased against the ball.

10. The handheld computer of claim 8, wherein the ball has a non-spherical outer surface.

11. The handheld computer of claim 8, wherein the ball has an outer surface having one or more depressions.

12. The handheld computer of claim 2, wherein the cover in the stand position has a corner that engages a notch formed in a rear face of the housing to allow the housing to remain in an inclined position when placed on a horizontal surface.

13. The handheld computer of claim 1, wherein the hinge assembly comprises a unitary tubular member that is fixedly connected to a first edge of the cover and pivotally connected to a second edge of the housing.

14. The handheld computer of claim 13, wherein the tubular member permits rotation of the cover about two different axes.

15. The handheld computer of claim 14, wherein the tubular member includes a ball and socket arrangement that permits rotation of the cover about a first axis extending along an edge of the housing and a second axis extending through the tubular member.

16. The handheld computer of claim 15, wherein the ball and socket arrangement permits the cover to abut a rear face of the housing when an inner face of the cover is oriented toward the rear face of the housing, the ball and socket arrangement preventing the cover from abutting the rear face of the housing when an outer face of the cover is oriented toward the rear face.

17. A handheld computer, comprising:

a housing; and

a cover movably connected to the housing by a unitary hinge assembly that enables the cover to be moved to at least two different positions, the cover providing a different function in each position.

18. The handheld computer of claim 17, wherein the unitary hinge assembly comprises an arm having one end connected to the cover and an opposite end terminating in a ball, the ball being configured to fit within a socket formed in an edge of the housing.

19. The handheld computer of claim 17, wherein the unitary hinge assembly permits the cover to be detached and reattached.

20. The handheld computer of claim 17, wherein the unitary hinge assembly permits the cover to be moved to at least three different positions including a closed position, an open position and a stand position.

21. A handheld computer, comprising:

a housing; and

a cover movably connected to the housing by a hinge assembly that enables the cover to be rotated about at least two different axes.

22. The handheld computer of claim 21, wherein the first axis extends along an edge of the housing and the second axis extends transversely to the edge of the housing.

23. The handheld computer of claim 21, wherein the hinge assembly comprises a ball and socket arrangement.

24. The handheld computer of claim 21, wherein the cover is rotatable about two different axes to at least three different positions, the cover providing a different function in each position.

25. The handheld computer of claim 24, wherein the hinge assembly enables the cover to assume a closed position, an open position, and a stand position.

26. The handheld computer of claim 25, wherein the cover in the closed position is configured to protect a display screen, the cover in the open position is configured to permit access to the display screen without increasing a footprint of the computer, and the cover in the stand position forms an outrigger for maintaining the housing in an inclined position when placed on a horizontal surface.

27. A handheld computer, comprising:

a housing;

a cover; and

means for pivotally coupling the cover to the housing for rotation about two different axes.

28. The handheld computer of claim 27, wherein the pivotal coupling means comprises a ball and socket arrangement.

29. The handheld computer of claim 27, wherein the pivotal coupling means enables the cover to move between at least two different positions, the cover providing a different function in each position.

30. The handheld computer of claim 27, wherein the pivotal coupling means enables the cover to move between at least three different positions, the cover providing a different function in each position.

31. The handheld computer of claim 30, wherein the pivotal coupling means enables the cover to move between a closed position, an open position, and a stand position.

32. The handheld computer of claim 31, wherein the cover in the closed position is configured to protect a a display screen, the cover in the open position is configured to permit access to the display screen without increasing a footprint of the computer, and the cover in the stand position forms an outrigger for maintaining the housing in an inclined position when placed on a horizontal surface.

33. A method of reconfiguring an encasement of a handheld computer to provide at least two different functions, the encasement including a housing and a cover pivotally connected thereto, the method comprising:

rotating the cover about at least two different axes to move the cover between at least two different positions, the cover providing a different function in each position.

34. The method of claim 33, wherein the cover is pivotally mounted to an edge of the housing, and the rotating step includes rotating the cover about an axis extending generally parallel to the edge of the housing.

35. The method of claim 33, wherein the cover is pivotally mounted to an edge of the housing, and the rotating step includes rotating the cover about an axis extending generally perpendicular to the edge of the housing.

36. The method claim 33, wherein the cover in at least one of the positions functions to protect the display screen from damage.

37. The method of claim 33, wherein the cover in at least one of the positions functions to maintain the housing at an inclined angle relative to a horizontal surface on which the computer is placed.

38. The method of claim 33, wherein the cover in at least one of the positions functions to permit access to the display screen.
