ABSTRACT:
A notebook computer is provided with a collapsible keyboard in which a dome sheet with elastomeric key return dome members thereon is horizontally shiftable through elevation and retraction strokes to respectively shift the keys between elevated operating positions in which the domes underlie and support the keys, and retracted positions in which the domes are shifted away from their key-underlying positions. A linkage member interconnected between the computer lid and a drive bar on the dome sheet creates initial triggering movements of the dome sheet through its elevation and retraction strokes in response to opening and closing of the lid. In response to these lid-created triggering movements of the dome sheet, a bistable spring structure connected to the drive bar takes control of the dome sheet and drives it through the balance of the stroke and then releasably retains the fully shifted dome sheet in the resulting stroke end position thereof.
