Abstract:
1. A portable computing device comprising a base, a lid and a hinge mechanism, the base including at least a keyboard disposed at a top surface of the base, the hinge mechanism comprising: a base link pivotally connected with the base such that the base link rotates about a first axis of rotation, the base link being in sliding communication with the lid; a lid link pivotally connected with the lid such that the lid link rotates about a second axis of rotation, the lid link being in sliding communication with the base; and a center pin pivotally connecting the base link with the lid link such that the base link and the lid link rotate about a third axis of rotation wherein the base link, the lid link, and the center pin cooperatively function to translate the lid over at least two planes of motion with respect to the base, wherein a first rotation of the lid with respect to the base is associated with a maximum horizontal translation of the lid with respect to the base, the maximum horizontal translation of the lid with respect to the base being larger than any other horizontal translation of the lid with respect to the base with the base being coupled with the lid by the hinge mechanism, the first rotation being measured from a closed position of the lid with respect to the base, the keyboard being hidden when the lid is in the closed position with respect to the base, the keyboard being revealed when the lid is not in the closed position with respect to the base, a second rotation of the lid with respect to the base is associated with a maximum vertical translation of the lid above the top surface of the base, the maximum vertical translation of the lid with respect to the base being larger than any other vertical translation of the lid with respect to the base with the base being coupled with the lid by the hinge mechanism, the second rotation being measured from the closed position of the lid with respect to the base, and the first rotation of the lid with respect to the base is larger than the second rotation of the lid with respect to the base.
