ABSTRACT:
A hinge assembly has a plurality of rollers which are pressed against an elastic washer by a shaft. The rollers and elastic washer are contained within a cylindrical retainer which is held in a fixed position relative to a first bracket, while the shaft is held in a fixed position relative to a second bracket so that, when either or both the first and second brackets are moved relative to each other, the roller move around the outside diameter of the shaft resisted by the elastic washer, providing a smooth resistance to the movement of the first bracket and/or second bracket relative to the other. An electronic digital device, having a display section with an adjustable viewing angle utilizing the improved hinge assembly, is shown in which the hinge assembly provides a smooth resistance for the movement of the display section relative to the base of the device.
