Abstract

A mobile communication device may include at least a lid member and a base member which are hingeably coupled together by a linkage mechanism. The device may include additional interface elements on an interface surface accessible when the device is in the closed position. A mobile communication device is provided which further comprises a rotatable member having an interface surface. The linkage mechanism actuates movement of the rotatable member from a first rotation state, such that the interface surface is accessible when the device is in a closed position, to a second rotational state, such that the interface surface is positioned between and concurrently viewable with inner surfaces of the lid and base members when the device is in an opened position. The linkage mechanism actuates the movement of the rotatable member responsive to movement of the device from the closed to the opened position and vice versa.

2. The device of claim 1, wherein the third surface includes at least one of a control surface, a graphical display, one or more keys, and a touch screen.

3. The device of claim 2, wherein the third surface is flush with the first surface when the rotatable member is in the second rotational state.

4. The device of claim 1, wherein the movement of the device from the closed position to the opened position comprises rotational movement of the first member with respect to the second member in a first direction of rotation;

the movement of the device from the opened position to the closed position comprises rotational movement of the first member with respect to the second member in a second direction of rotation opposite to the first direction of rotation;
