Abstract:
A friction torque hinge comprising:a rotatable shaft; one or more frictional elements each having an outer edge, an outer edge feature and a surface to engage the shaft, wherein each of the frictional elements are mounted on the shaft such that their outer edges and outer edge features collectively form an outer element perimeter; a molded element housing formed over each of the frictional elements using a flowable material that hardens around the outer element perimeter such that the element housing has an inner cavity having a shape that intimately matches the outer element perimeter of the frictional elements and such that element housing is prevented from rotating relative to the frictional elements; and a lubricating substance trapped between the frictional elements and the shaft.
