Abstract

A portable computer has a base housing to which a display housing is pivotally secured for movement between open and closed orientations. Extending across a top side opening of the base housing is a keyboard assembly which may be removed from the top side of the base housing. The removed keyboard assembly may be vertically supported on a rear portion of the base housing, to permit access to the base housing through its now exposed top side opening, by means of tabs formed on a rear side edge of the keyboard support plate structure and removably insertable in corresponding vertically extending slots in the top side wall of the base housing. This vertical support of the removed keyboard assembly prevents it from being misplaced, reduces the potential for damaging it by laying it aside on an adjacent work space area, holds the vertically supported keyboard assembly away from the display screen to prevent the keyboard assembly from scratching it. Additionally, the vertical support of the removed keyboard assembly may be achieved without disconnecting the ribbon cable that operatively couples the keyboard assembly to the associated electronics within the base housing. When the keyboard assembly is operatively installed on the top side of the base housing, the rear side edge tabs on the support plate are removably received in corresponding horizontal slots in the base housing.

Claims

1. A personal computer, comprising:

a base housing;

a display connected to the base housing by a hinge;

a keyboard assembly; and

an interlock system coupled to the base housing and the keyboard assembly,

wherein the interlock system maintains the keyboard assembly at a plurality of selected angular positions.

2. The personal computer as recited in claim 1, wherein the interlock system comprises a plurality of interlocking tabs and slots.

3. The personal computer as recited in claim 2, wherein the tabs and slots are positioned to lock the keyboard at one of the plurality of selected angular positions.

4. The personal computer as recited in claim 3, wherein the tabs are disposed on the keyboard assembly and the slots are disposed in the base housing.

5. The personal computer as recited in claim 1, wherein the keyboard assembly is disposed in a portable computer.

6. The personal computer as recited in claim 1, wherein the keyboard assembly is disposed in a notebook computer.

7. The personal computer as recited in claim 1, further comprising a conductive cable that maintains an electrical connection between an electrical connection device mounted in the housing and the keyboard at each of the plurality of selected angular positions.

8. A portable computer, comprising:

a base having a recess;

a keyboard sized to fit within the recess;

an electrical connector disposed to electrically couple the base to the keyboard; and

an interlock system designed to hold the keyboard against pivotal motion at an angular position, the angular position permitting access to the recess otherwise containing the keyboard.

9. The portable as recited in claim 8, further comprising a display connected to the base by a hinge.

10. The personal computer as recited in claim 9, wherein the interlock system comprises a plurality of interlocking tabs and slots.

11. The personal computer as recited in claim 10, wherein the tabs and slots are positioned to lock the keyboard at one of a plurality of selected angular positions.

12. The personal computer as recited in claim 11, wherein the tabs are disposed on the keyboard and the slots are disposed in the base.

13. The personal computer as recited in claim 8, wherein the keyboard is disposed in a portable computer.

14. The personal computer as recited in claim 8, wherein the keyboard is disposed in a notebook computer.

15. The personal computer as recited in claim 8, wherein the electrical connector comprises a flexible cable.

16. A personal computer, comprising:

a base;

a display connected to the base by a hinge;

a keyboard assembly; and

an interlock system comprising a plurality of tabs and a plurality of corresponding slots that permit the keyboard assembly to be locked at one of a plurality of selected angular positions.

17. The personal computer as recited in claim 16, wherein the tabs are disposed on the keyboard assembly and the slots are disposed in the base.

18. The personal computer as recited in claim 16, wherein the keyboard assembly is disposed in a portable computer.

19. The personal computer as recited in claim 16, wherein the keyboard assembly is disposed in a notebook computer.

20. The personal computer as recited in claim 16, further comprising a conductive cable that maintains an electrical connection between an electrical connector device mounted in the housing and the keyboard during each of the plurality of selected angular positions.
