Abstract
A hinge assembly includes a guiding unit connected between and slidable relative to first and second hinge units along arcuate lines. The second hinge unit has a pivot shaft extending through first and second rings, and a resilient washer. The second ring is rotatable on the pivot shaft relative to the first ring and has a radial extension member telescopically connected to a pivotal arm of the first hinge unit. The resilient washer pushes the second ring against the first ring. A protrusion of the first ring slides along a contact surface of the second ring having a groove so that a variable friction toque is created against relative movement of the first and second hinge units.
