  • Patent number: 6301748
    Abstract: The present invention relates to a clip type friction hinge device, which can be conveniently assembled and can freely adjust the torque to a desired rotary direction. The clip type friction hinge device of the present invention comprises a housing having an axial hole and a fixing slit formed at a lower portion of the axial hole; a rotary axis which is inserted to the housing to be rotatable; a torsion spring which elastically supports the rotary axis for the housing and is comprised of a pair of semi-cylindrical spring members; and a plurality of C type clips which are elastically inserted to the outer circumference of the torsion spring.
