Hinge mechanism for mobile electronic device
First Claim
1. A hinge mechanism for a mobile electronic device,comprising:
- a first leaf comprising a first pivot axis and a second pivot axis, the first and second pivot axes being spaced from one another and fixed relative to the first leaf;
a second leaf comprising a third pivot axis and a fourth pivot axis, the third and fourth pivot axes being spaced from one another and fixed relative to the second leaf, the first, second, third and fourth pivot axes being substantially parallel to one another;
a first linkage pivotally coupled to the first leaf such that the first linkage is pivotable about the first pivot axis relative to the first leaf, and pivotally coupled to the second leaf such that the first linkage is pivotable about the fourth pivot axis relative to the second leaf; and
a second linkage pivotally coupled to the first leaf such that the second linkage is pivotable about the second pivot axis relative to the first leaf, and pivotally coupled to the second leaf such that the second linkage is pivotable about the third pivot axis relative to the second leaf;
wherein the first leaf and the second leaf are pivotable, between a closed position and an open position, at least about 180°
relative to one another in a plane substantially perpendicular to the first, second, third and fourth pivot axes; and
wherein, when the hinge mechanism is in the closed position, the first linkage and the second linkage are transverse to one another when viewed in an axial direction of the first, second, third and fourth pivot axes;
wherein the first leaf and the second leaf are pivotable, between a fully closed position and an open position, wherein the first and second leaves extend in opposite directions from each other in the open position, and wherein the first leaf pivots about 180°
relative to the second leaf between the closed and open positions; and
wherein, when the mobile device is in the open position, the distance between the first pivot axis and the third pivot axis is substantially different than the distance between the second pivot axis and the fourth pivot axis.

Abstract
A hinge mechanism for a mobile electronic device includes a first leaf comprising first and second fixed pivot axes and a second leaf comprising third and fourth fixed pivot axes, the four pivot axes being substantially parallel to one another. A first linkage is pivotally coupled to the first leaf at the first pivot axis and pivotally coupled to the second leaf at the fourth pivot axis. A second linkage is pivotally coupled to the first leaf such at the second pivot axis and pivotally coupled to the second leaf at the third pivot axis. The first and second leaves are pivotable at least about 180° relative to one another. A cam mechanism can be included to bias the pivotal motion of the leaves. An FPC or other electrical connector linking the leaves can pass through a passage in at least one of the linkages.
