ABSTRACT:
A hinge fastens a display screen to a keyboard base, and uses a frictional force generated by one or more compressed friction washers to control angular motion of the display screen with respect to the keyboard base. The hinge includes two shoulders defining inwardly-facing flat abutment surfaces separated by a first distance, the two shoulders being disposed on the keyboard base, and a knuckle having a pair of outwardly-facing flat abutment surfaces separated by a second distance which is less than the first distance, the knuckle being disposed on the display screen. Also included in the hinge is at least one compressible friction washer, disposed between the knuckle and the two shoulders, and having a thickness which is greater than a difference between the first distance and the second distance, but which is compressible to less than the difference. Each of the two shoulders, the knuckle, and the at least one compressible friction washer has an alignable throughbore. A pin fits through the alignable throughbores of the two shoulders, the knuckle, and the at least one compressible friction washer.
