Abstract
Abstract A keyboard structure is supported on the top side of a base housing portion of a compact portable computer such as a notebook or laptop computer. In one keyboard embodiment pins on the keyboard are slidably received in slots on upstanding support brackets on the base housing, and in another keyboard embodiment the keyboard is movably secured to the base housing by pivotable support bars. When the lid portion of the computer is opened, the keyboard is in a storage/transport orientation in which it is generally parallel to the bottom wall of the base housing. With the lid portion opened, and the computer resting on a horizontal support surface, the keyboard may be used in this storage/transport orientation. The keyboard is supported on the base housing in a manner also permitting the keyboard to be moved forwardly relative to the base housing and be downwardly pivoted to a forwardly and downwardly sloped tilted use orientation in which the keyboard is disposed generally forwardly of the base housing, with a lower front edge portion of the keyboard downwardly engaging the support surface upon which the computer rests. In this manner, the notebook computer keyboard is disposed at an angle and elevation emulating the use orientation of a separate desktop computer keyboard.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
275 words
A portable computer comprising: a base housing having a bottom side restable on a generally horizontal support surface, a top side upwardly spaced apart from and disposed generally parallel to said bottom side, and a front side generally perpendicular to said top side; a keyboard structure having a body portion with a top side upon which a series of manually movable key elements are operably disposed; and linkage means for connecting said keyboard structure to said base housing for selective translational and pivotal movement relative thereto between: (1) a storage/transport and first use orientation in which said keyboard structure body portion is positioned on and generally parallel to said top side of said base housing with said key elements facing upwardly, and (2) a second use orientation in which said keyboard structure body portion is positioned generally forwardly of said base housing, and is sloped forwardly and downwardly relative thereto in a manner permitting a front portion of said keyboard structure body portion to be rested on the support surface, said base housing having first and second opposite, parallel sides each extending perpendicularly to said top, front and bottom sides of said base housing, and said linkage means including: first and second spaced apart elongated support brackets positioned on said top side of said base housing and longitudinally extending parallel to said first and second sides of said base housing, said first and second support brackets having elongated slots formed therein and extending parallel to their lengths, and a pair of pin structures secured to opposite sides of said keyboard structure body portion and captively retained in said slots for movement along the lengths thereof.
Claim 2
Dependent Claim
275 words
A portable computer comprising: a base housing having a bottom side restable on a generally horizontal support surface, a top side upwardly spaced apart from and disposed generally parallel to said bottom side, and a front side generally perpendicular to said top side; a keyboard structure having a body portion with a top side upon which a series of manually movable key elements are operably disposed; and linkage means for connecting said keyboard structure to said base housing for selective translational and pivotal movement relative thereto between: (1) a storage/transport and first use orientation in which said keyboard structure body portion is positioned on and generally parallel to said top side of said base housing with said key elements facing upwardly, and (2) a second use orientation in which said keyboard structure body portion is positioned generally forwardly of said base housing, and is sloped forwardly and downwardly relative thereto in a manner permitting a front portion of said keyboard structure body portion to be rested on the support surface, said base housing having first and second opposite, parallel sides each extending perpendicularly to said top, front and bottom sides of said base housing, and said linkage means including: first and second spaced apart elongated support brackets positioned on said top side of said base housing and longitudinally extending parallel to said first and second sides of said base housing, said first and second support brackets having elongated slots formed therein and extending parallel to their lengths, and a pair of pin structures secured to opposite sides of said keyboard structure body portion and captively retained in said slots for movement along the lengths thereof.
Claim 3
Dependent Claim
14 words
The portable computer of claim 1 wherein: said portable computer is a notebook computer.
Claim 4
Dependent Claim
66 words
The portable computer of claim 1 wherein: said top side of said base housing has an opening therein through which the interior of said base housing outwardly opens, said keyboard structure, in said storage/transport and first use orientation thereof, covers said opening, and said keyboard structure, in said second use orientation thereof, uncovers said opening to permit access therethrough to the interior of said base housing.
Claim 5
Dependent Claim
46 words
The portable computer of claim 1 wherein: each of said slots has downturned opposite end portions that act as detents to restrain the movement of said pin structures parallel to the lengths of said slots when said pin structures are received in said slot end portions.
Claim 6
Dependent Claim
393 words
A notebook computer comprising: a base housing having a bottom side restable on a generally horizontal support surface, a top side upwardly spaced apart from and disposed generally parallel to said bottom side, a front side generally perpendicular to said top side, and an opening in said top side through which the interior of said base housing outwardly extends; a lid housing secured to a rear side portion of said base housing for pivotal movement relative to said base housing between a closed position in which said lid housing extends across and parallel to said top side of said base housing, and an open position in which said lid housing extends upwardly from said base housing at an angle to said top side thereof; a keyboard structure having a body portion with a top side upon which a series of manually movable key elements are operably disposed; and linkage means for connecting said keyboard structure to said base housing for selective translational and pivotal movement relative thereto, with said lid housing in said open position thereof, between: (1) a storage/transport and first use orientation in which said keyboard structure body portion is positioned on and generally parallel to said top side of said base housing with said key elements facing upwardly, and said keyboard structure body portion covering said opening in said top side of said base housing, and (2) a second use orientation in which said keyboard structure body portion is positioned generally forwardly of said base housing, is sloped forwardly and downwardly relative thereto in a manner permitting a front portion of said keyboard structure body portion to be rested on the support surface, and uncovers said opening in said top side of said base housing, said base housing having first and second opposite, parallel sides each extending perpendicularly to said top, front and bottom sides of said base housing, and said linkage means including: first and second spaced apart elongated support brackets positioned on said top side of said base housing and longitudinally extending parallel to said first and second sides of said base housing, said first and second support brackets having elongated slots formed therein and extending parallel to their lengths, and a pair of pin structures secured to opposite sides of said keyboard structure body portion and captively retained in said slots for movement along the lengths thereof.
