Abstract
Abstract A portable computing device includes pivoting and hinging mechanisms which enable its housing to reconfigure to function in multiple modes. In one configuration the device functions as a laptop computer with keyboard input. In another configuration the device folds into a compact, hand-held, pen-based computer. In another configuration the device folds around the display for protection during transport. A set of adjustable stops enable easy and repeatable transitions between the different configurations.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
288 words
A foldable keyboard, comprising: a) a first keyboard section having first front edge, a first rear edge, a substantially planar first top surface, and a plurality of keys protruding from said first top surface; b) a second keyboard section having a second front edge, a second rear edge, a substantially planar second top surface and a plurality of keys protruding from said second top surface; c) a first keytop surface formed from the tops of said keys protruding from said first keyboard section; d) a second keytop surface formed from the tops of said keys protruding from said second keyboard section; e) a first hinge, said first hinge adjacent to said first and second rear edges, connecting said first and second keyboard sections and allowing said first and second keyboard sections to rotate with respect to each other from an extended position to a collapsed position, said first hinge having an axle whose axis of rotation with respect to said first keyboard section is at least as high as the said keytop surfaces in the said extended position; f) a second hinge, said second hinge located closer to said first and second front edges than said first hinge, said second hinge connecting said first and second keyboard sections, and said second hinge having no axle with the same axis of rotation with respect to said first keyboard section as the said axle of the said first hinge, whereby said first and second hinges allow said keyboard to fold from a more compact collapsed condition to an extended position for use, and during said use said second hinge retracts to facilitate typing, and whereby due to said rearward location of said first hinge, said first hinge need not retract.
Claim 2
Dependent Claim
288 words
A foldable keyboard, comprising: a) a first keyboard section having first front edge, a first rear edge, a substantially planar first top surface, and a plurality of keys protruding from said first top surface; b) a second keyboard section having a second front edge, a second rear edge, a substantially planar second top surface and a plurality of keys protruding from said second top surface; c) a first keytop surface formed from the tops of said keys protruding from said first keyboard section; d) a second keytop surface formed from the tops of said keys protruding from said second keyboard section; e) a first hinge, said first hinge adjacent to said first and second rear edges, connecting said first and second keyboard sections and allowing said first and second keyboard sections to rotate with respect to each other from an extended position to a collapsed position, said first hinge having an axle whose axis of rotation with respect to said first keyboard section is at least as high as the said keytop surfaces in the said extended position; f) a second hinge, said second hinge located closer to said first and second front edges than said first hinge, said second hinge connecting said first and second keyboard sections, and said second hinge having no axle with the same axis of rotation with respect to said first keyboard section as the said axle of the said first hinge, whereby said first and second hinges allow said keyboard to fold from a more compact collapsed condition to an extended position for use, and during said use said second hinge retracts to facilitate typing, and whereby due to said rearward location of said first hinge, said first hinge need not retract.
Claim 3
Dependent Claim
15 words
The foldable keyboard of claim 1, wherein said first hinge is a simple pivoting joint.
Claim 4
Dependent Claim
30 words
The foldable keyboard of claim 1, wherein said first and second keyboard sections rotate relative to each other about the axis which passes through said axle of said first hinge.
Claim 5
Dependent Claim
78 words
The foldable keyboard of claim 1, wherein said second hinge includes a first front axle, a second front axle, and a link connecting said first and second front axles, whereby in said extended position, said first and second front axles and said link remain beneath the keytop surfaces, and in said collapsed condition, said link crossed the first and second keytop surfaces and forms a brace to maintain a fixed spacing between said first and second keyboard sections.
Claim 6
Dependent Claim
26 words
The foldable keyboard of claim 1, wherein said rear axle, said first front axle, and said second front axle have rotation axes which are mutually parallel.
Claim 7
Dependent Claim

The foldable keyboard of claim 1, wherein said first and second hinges comprise pairs of lugs pivotally connected by axels.
Claim 8
Dependent Claim
24 words
The foldable keyboard of claim 1, wherein the relative motion between connected parts in said first and second hinges is restricted to relative rotation.
Claim 9
Dependent Claim
24 words
The foldable keyboard of claim 1, wherein the relative motion between connected parts in said first and second hinges does not include relative translation.
