Compact computing device having a compressible keyboard

DETAILED DESCRIPTION This invention provides portable electronic devices, such as notebook computers with the capability of a full-size or nearly full-size keyboard.
In specific embodiments, the present invention provides laptops, notebooks and sub-notebooks with increased size keyboards which approximate the size of a typical desktop computer keyboard when in use, but when in a non-use configuration smaller dimensions conforming to conventional form factors for these devices.
The increased keyboard size permits comfortable typing with layouts familiar to users without sacrificing the light weight and compactness normally associated with smaller portable computers.
In an embodiment of the invention, a portable notebook computer is provided which includes a top housing having a display and a bottom housing having a keyboard, with the two housings connected with a hinge for pivotally deploying the keyboard from a storage position.
The keyboard has several sections which are compressed in the storage position but expand when deployed to a keyboard having the layout and size of a desk top keyboard.
In another embodiment of the present invention, the keyboard sections are provided with collapsible skirts to provide additional space for the keyboard sections to move into closer proximity.
The collapsible skirts may also employ a rigid member to provide a firm upper surface for the key and may also be used as a portion of the key plunger.
An advantage of the present invention is the keyboard is a smaller keyboard to fit in the portable computer form factor but with the size and spacing of a larger or desktop keyboard.
Another advantage of the present invention is there is no need for a complex mechanical structure to guide and secure the individual keys as required in the prior art.
A further advantage of the present invention is the invention can be used with more conventional key switches because it does not rely on keys made as part of a molded flexible assembly.
In addition, the flexible skirt allows the keys to retain a more conventional shape which appeals to the user and helps to prevent foreign objects from becoming lodged between the keys
