Patent ID: 7610067

Claim:
A portable communication device comprising: a first housing; a second housing opened from and closed onto the first housing by a hinge about a first hinge axis; a third housing disposed between the first and second housings, the third housing being rotated about a second hinge axis, which is separated from the first hinge axis and follows a vertical direction, so as to be disposed parallel to the first and second housings, the third housing folded or unfolded about a third hinge axis perpendicular to the second hinge axis; and a swing hinge module connecting the third housing to the first housing, so that the third housing can be rotated about the second and third hinge axes, wherein the swing hinge module comprises: a shaft assembly having a first shaft providing the third hinge axis and a second shaft providing the second hinge axis and extending in a direction perpendicular to the first shaft; an upper hinge member engaged with the second shaft so as to be rotated together with the second shaft; a lower hinge member restricted by a mounting member so as to be coaxial with the upper hinge member, the lower hinge member being independent from the movement of the second shaft; a resilient member disposed between the upper and lower hinge members, for applying a constant force when the third housing is swung; and a stopping means disposed between the upper and lower hinge members, for limiting a rotation angle of the second shaft.
