ABSTRACT:
A full function foldable keyboard for an electronic device and in particular a mobile communication terminal having first, second and third body elements is disclosed wherein hinged together second and third body elements are arranged for pivotal movement relative to one another about a lengthwise axis passing through the hinge as the device is moved between its operative closed and open positions. The second body element is arranged for rotational movement with respect to the first body element about a pivot axis passing lengthwise through the first and second body elements and is offset from one edge of the first body element and the hinge edge of the second body element. The third body element moves with transverse sliding movement along an angular linear path with respect to the first body element as the device is moved between its operative closed and open positions. A communication keyboard is accessible for usage in the closed operative position and a full function keyboard is exposed and accessible for usage in the open operative position. A display is constructed in the first body element.
