Abstract:
A mobile phone or other electronic device is provided with an improved friction hinge with a radial range of motion greater than 180 degrees and with detents at both ends of travel. The friction hinge can include an asymmetrical cam in conjunction with a single tab on a follower. Advantageously, the electronic device with the improved friction hinge can allows a full 360 degree range of motion with any number of detents at any radial position.
