Abstract:
A wireless handheld device comprises a lower casing having a bottom end and a top end and a lid having a bottom end and a top end. The top end of the lid is rotatably coupled to the top end of the lower casing with at least one hinge component such that the handheld device is rotatable from a closed position to an open position and from an open position to a closed position. The lid and the lower casing have adjacent facing surfaces when in the closed position. When the wireless handheld device is in the closed position, at least the bottom end of the lid is displaceable relative to the lower casing generally in an axial direction of the hinge component such that the facing surfaces become misaligned for easy grasping of the lower casing and the lid.
