ABSTRACT:
An expandable keyboard in accordance with the present invention provides a full-size or expanded keyboard for typing which folds to minimize size during transport or storage, and can be converted to substantially twice its folded length for use. Its use of sliding segments permits a straight hinge line for folding. Its operating mechanism supports a large number of electrical interconnections between the hinged wing section or sections and the central platform, and provides for straight-line engagement as well as environmental and ESD protection of the mating electrical connectors. It permits the operation of removable modules such as PCMCIA cards or fixed circuitry such as speakers or keypads in the wing section or sections in both their open and closed positions. It includes a central keyboard assembly and a first assembly comprising a first segment and a first wing. The central keyboard assembly includes one or more keys and a platform. The first wing is pivotally connected along one side to one side of the platform about a first axis and is pivotable to a closed position where the first wing rests substantially on the platform and to an open position where the first wing provides an extension of the platform. The first segment is slidably connected to the first wing and is moveable to a first position which exposes the first axis and permits the first wing to pivot about the first axis and to a second position which covers the first axis and substantially prevents the first wing from pivoting about the first axis. The expandable keyboard may also include a second assembly comprising a second segment and a second wing, pivotally connected along one side of the platform about a second axis, which operates in the same manner as the first wing.
