Abstract
Abstract A method and apparatus is described for reducing the width of a keyboard, such as a keyboard of a portable computing device, for folding the keyboard from a first width of the keyboard in operative position to a second width of the keyboard in a storage position. The keyboard has a plurality of keyboard sections each having a plurality of keys, where the operative position of the keyboard has the sections disposed in a line. The keyboard folds such that the keyboard sections are vertically adjacent to each other. The keys of the keyboard sections are compressed for storage to take up their travel and thereby conserve storage volume as well as storage width. Multiple implementations are disclosed, including keyboards that fold such that the keys of one section are in contact with the keys of another section, and keyboards that fold such that the keys are not in contact with keys of another section.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
208 words
A method for reducing the width of a keyboard from a first width of the keyboard in operative position to a second width of the keyboard in a storage position, where the keyboard is an electronic type for use with portable computing devices, comprising: providing a keyboard comprising a plurality of keyboard sections including at least a first keyboard section and a second keyboard section, each keyboard section having a top face from which a plurality of keys extend, an opposite bottom face, and opposite sides, and where the operative position of the keyboard has the sections disposed side-by-side in a line; providing a component having a first slot, the first and the second keyboard sections being slidably engaged in the first slot when the keyboard is in operative position; sliding the first keyboard section relative to the component having the first slot until the first keyboard section disengages from the first slot; folding the keyboard such that a face of the first keyboard section selected from the group consisting of the top face and the bottom face is adjacent to a face of the second keyboard section selected from the group consisting of the top face and the bottom face to place the keyboard in storage position.
Claim 2
Independent Claim
208 words
A method for reducing the width of a keyboard from a first width of the keyboard in operative position to a second width of the keyboard in a storage position, where the keyboard is an electronic type for use with portable computing devices, comprising: providing a keyboard comprising a plurality of keyboard sections including at least a first keyboard section and a second keyboard section, each keyboard section having a top face from which a plurality of keys extend, an opposite bottom face, and opposite sides, and where the operative position of the keyboard has the sections disposed side-by-side in a line; providing a component having a first slot, the first and the second keyboard sections being slidably engaged in the first slot when the keyboard is in operative position; sliding the first keyboard section relative to the component having the first slot until the first keyboard section disengages from the first slot; folding the keyboard such that a face of the first keyboard section selected from the group consisting of the top face and the bottom face is adjacent to a face of the second keyboard section selected from the group consisting of the top face and the bottom face to place the keyboard in storage position.
Claim 3
Dependent Claim
33 words
The method of claim 1, further comprising the step of collectively compressing the keys of the keyboard sections to reduce the thickness of the keyboard sections while placing the keyboard in storage position.
Claim 4
Dependent Claim
20 words
The method of claim 1 wherein the first and the second keyboard section are mechanically interconnected by an interconnection mechanism.
Claim 5
Dependent Claim
18 words
The method of claim 3, wherein the interconnection mechanism comprises a hinge at a face of the keyboard.
Claim 6
Dependent Claim
81 words
The method of claim 4, wherein the interconnection mechanism comprises a plurality of hinges such that no hinge is at or above the top face of a keyboard section, and the interconnection mechanism retains the keyboard sections adjacent to each other with little or no play when the keyboard is in operative position, and wherein the top face of the first keyboard section is adjacent to the top face of the second keyboard section when the keyboard is in storage position.
Claim 7
Dependent Claim
167 words
A keyboard assembly for portable computing devices, the keyboard assembly having an operative position and a storage position, the keyboard assembly comprising: a first and a second keyboard section each having a plurality of keys; a mechanical interconnection device interconnecting the first and the second keyboard section in line for an operative position, where the mechanical interconnection device is operable to permit the first and second keyboard section to be moved to a position vertically adjacent to each other for a storage position; apparatus for electrically interconnecting the first and the second keyboard section when the keyboard is in operative position; apparatus for electrically connecting the first keyboard section to the portable computing device; a component having a slot within which the first and second keyboard sections are slidably engaged when the keyboard is in operative position; and wherein when the keyboard is in storage position the first keyboard section is engaged within the said slot and the second keyboard section is not engaged in said slot.
Claim 8
Dependent Claim
167 words
A keyboard assembly for portable computing devices, the keyboard assembly having an operative position and a storage position, the keyboard assembly comprising: a first and a second keyboard section each having a plurality of keys; a mechanical interconnection device interconnecting the first and the second keyboard section in line for an operative position, where the mechanical interconnection device is operable to permit the first and second keyboard section to be moved to a position vertically adjacent to each other for a storage position; apparatus for electrically interconnecting the first and the second keyboard section when the keyboard is in operative position; apparatus for electrically connecting the first keyboard section to the portable computing device; a component having a slot within which the first and second keyboard sections are slidably engaged when the keyboard is in operative position; and wherein when the keyboard is in storage position the first keyboard section is engaged within the said slot and the second keyboard section is not engaged in said slot.
Claim 9
Dependent Claim
33 words
