Patent ID: 10228732

Abstract:
A friction hinge is described. Generally, the friction hinge provides a variable torque profile for a movable component. In an example, the friction hinge includes a hinge frame; a pivot member pivotably engaged with the hinge frame, the pivot member being attached to a support component movably attached to a device; an elongated member attached to the to hinge frame, the elongated member having a ramped surface on at least a first portion of the elongated member; and an engagement member slidably engaged with the elongated member, the engagement member configured to slide along the elongated member during pivoting of the pivot member relative to the hinge frame, the sliding of the engagement member along the taped surface of the elongated member causing variations in a sliding friction based on an amount of change in surface height over longitudinal distance of the ramped surface and contributing to a torque profile of the hinge.
