TORSION FRICTION SPRING HINGE

摘要

The present invention is a spring hinge (10) for generating torque. The spring hinge (10) includes a shaft (12) and a single helical element (14). The shaft (12) has a surface (13) with an outer diameter and is capable of rotation. The single helical element (14) is wrapped about the shaft (12). The helical element (14) includes a first end (16) and a second end (18). The helical element (14) produces a variable torque between the first (16) and second ends (18).
