Abstract
Abstract A collapsible keyboard that is collapsible between a deployed configuration in which the keyboard is generally planar and a collapsed configuration, the keyboard being foldable about three substantially parallel axes between the deployed and collapsed configurations, the keyboard having four rigid subframes for supporting keys, each subframe being pivotally connected at a folding axis to an adjacent subframe. The keyboard preferably has support frames supporting keys thereon. The keys are slidable and are connected by flexible connectors that span the axes. The keyboard can be locked in either the collapsed or deployed configuration and can be combined with a remote communication unit.
