TORQUE HINGE WITH CLUTCH MECHANISM

WIPO Patent Application WO/2022/254916

A1

Provided is a novel torque hinge with which a driven member can be rotated with respect to a driving member with a sufficiently small force by performing a required operation, even if an inner ring 4 and an outer ring 6 are connected by a required frictional force by a connection member 8. A coil spring (89) having a pair of hook parts (92) is mounted on the outer peripheral surface of the outer ring (6), and the outer ring (6) is supported by a cylindrical support member (43). A control member (72) for controlling the coil spring (89) is assembled in series in the axial direction on the support member (43), and the control member (72) makes it possible to rotate around an axis of rotation (o1) shared by the inner ring (4) and the outer ring (6) with respect to the support member (43). The support member (43) and the control member (72) are provided with hook grooves (48 and 82) in which the pair of hook parts (92) of the coil spring (89) are respectively engaged. The coil spring (89) is configured to hold or open the outer ring (6) by means of a required operation.
