Abstract: Embodiments of the invention include a portable device hinge having an elastomer urging element that is used to supply the necessary force for controlled rotation of a main part and a flip part. Embodiments of the invention include low part count hinges. Embodiments of the invention also include hinges that permit pass-through of wiring between a flip part and a main part. A handset of the invention includes a flip part and a main part with one or more hinges of the invention controlling rotation between the flip part and the main part. Preferred embodiment handsets have wiring that passes though the can and the elastomer urging element of a hinge of the invention.

Abstract: The invention provides a dual axis hinge for handheld devices. A preferred embodiment is a self-contained hinge that provides controlled rotation about two axes, e.g., perpendicular x- and y-axes. Controlled rotation about an x-axis includes fully open and closed biased positions, and also preferably provides self-open and/or self-close assistance when predetermined rotational points about the x-axis are reached. Controlled rotation about a y-axis provides a bias position, e.g., 0°. Additionally, in the preferred embodiment both negative and positive rotation about the y-axis are permitted, and hard stops are defined at limits of negative and positive rotation. In a preferred embodiment hinge, a unitary main body supports x-axis and y-axis rotational control sub-assemblies. The main body is preferably substantially hollow, with bores that provide a path through which wiring, e.g., flex circuit, may be routed through. Embodiments of the invention also provide hinges with low part counts, e.g.
