FRICTION HINGE WITH SELECTIVELY TIGHTENING BANDS

摘要

An inventive friction hinge is disclosed that uses two or more bands (3, 13) each operating in their loosening mode of operation. The loosening mode is used to take advantage of the more reliable frictional characteristics that it provides. Each band wraps nearly around the hinge pin (7). Any number of bands can be used in each direction to obtain the desired torque characteristics. The novel friction hinge exhibits no lost motion and very slight spring-back.
