Abstract

A handheld computer comprises a housing and a cover removably connected thereto by a universal hinge assembly. The universal hinge assembly includes a tubular member or arm having a proximal end fixedly (non-rotatably) secured to an edge of the cover and a distal end pivotally coupled to an edge of the cover. The pivotal coupling may comprise a ball and socket arrangement, a pin and slot arrangement, or any other type of coupling arrangement that enables universal pivoting movement and releasable attachment between the cover and the housing. The cover may include a cushion designed to abut a display screen mounted in the housing when the cover is in a closed position. A method of reconfiguring an encasement of a handheld computer having a cover releasably coupled thereto includes removing the first cover and replacing it with a second cover of a different type.

Claims

1. A handheld computer, comprising:

a cover releasably connected to the housing by a universal hinge assembly.

2. The handheld computer of claim 1, wherein the universal hinge assembly allows universal pivotal motion between the cover and the housing.

3. The handheld computer of claim 1, wherein the cover has an inner surface that faces a display screen when the cover is in a closed position, and wherein the inner surface of the cover faces a rear face of the housing when the cover is in an open position.

4. The handheld computer of claim 1, wherein the cover has an inner surface that faces a display screen when the cover is in a closed position, and wherein the inner surface of the cover engages a horizontal work surface when the cover is in a stand position that maintains the housing at an inclined angle relative to the work surface.

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

6. The handheld computer of claim 5, wherein the ball and socket arrangement includes a ball connected to the cover and a corresponding socket formed in an edge of the housing.

7. The handheld computer of claim 6, further including a pair of movable pads located within the socket on opposite sides of the ball for releasably receiving the ball therebetween.

8. The handheld computer of claim 7, wherein the pads are resiliently biased inwardly against the ball.

9. The handheld computer of claim 6, wherein the ball has a non-spherical outer surface.

10. The handheld computer of claim 6, wherein the ball has an outer surface including one or more depressions.

11. The handheld computer of claim 1, wherein the universal hinge assembly comprises a pin and slot arrangement.

12. The handheld computer of claim 11, wherein the pin and slot arrangement includes a pin connected to the cover and a corresponding slot formed in an edge of the housing.

13. The handheld computer of claim 1, wherein the universal hinge assembly includes a tubular member fixedly coupled to a first edge of the cover and pivotally coupled to a second edge of the housing.

14. The handheld computer of claim 13, wherein the pivotal coupling is provided by a ball and socket arrangement.

15. The handheld computer of claim 14, wherein the ball and socket arrangement includes a ball provided on a distal end of the tubular member and a corresponding socket provided in the second edge of the housing.

16. The handheld computer of claim 13, wherein the pivotal coupling is formed by a pin and slot arrangement.

17. The handheld computer of claim 16, wherein the pin and slot arrangement includes a pin provided on a distal end of the tubular member and a corresponding slot provided in the second edge of the housing.

18. A handheld computer, comprising:

a housing;

a first cover configured for releasable coupling to the housing; and

a second cover configured for releasable coupling to the housing,

wherein the first and second covers are of different types and one of the first and second covers is releasably coupled to the housing.

19. The handheld computer of claim 18, wherein the first and second covers differ from each other by having different indicia on outer surfaces thereof.

20. The handheld computer of claim 19, wherein the indicia on the outer surfaces of the first and second covers are selected from colors, patterns, textures, designs, pictorial images, graphic image, relief image, and combinations thereof.

21. The handheld computer of claim 19, wherein the indicia on the outer surfaces of the first and second covers are selected from business identifiers, sports team identifiers, educational school identifiers, names or initials, logos, and combinations thereof.

22. A handheld computer, comprising:

a housing; and

a cover releasably connected to the housing by a hinge assembly that allows universal pivoting movement between the cover and the housing.

23. The handheld computer of claim 22, wherein the hinge assembly comprises a ball and socket arrangement.

24. The handheld computer of claim 23, wherein the ball and socket arrangement includes a ball provided on a distal end of a tubular member attached to the cover and a corresponding socket provided in an edge of the housing.

25. The handheld computer of claim 24, wherein the socket includes a pair of pads slidably mounted in the socket on opposite sides of the ball and biased into contact therewith.
