ABSTRACT:
This invention relates to a hinge which needs only small force to be turned in one rotational direction and relatively larger force to be turned in the opposite direction. The hinge comprises a pair of hinge members each having a cylindrical end and a fixing portion, the fixing portion having at least one aperture defined therein. An intermediate member is disposed between and pivotally connected to the pair of hinge members, the intermediate member having opposite cylindrical ends respectively aligned with and adjacent to the cylindrical ends of the pair of hinge members. A pair of helical springs with leads extending in directions opposite to each other are retained around and have different magnitudes of retaining forces acting upon corresponding adjacent ends of the intermediate member and the pair of hinge members.
