A hinge having stationary and turnable components which respectively carry cams which cooperate with each other to displace the turnable component upwardly with respect to the stationary component during opening movement while permitting the turnable component to move downwardly with respect to the stationary component during closing movement. In addition, a spring structure acts on the turnable component to urge the latter to carry out its closing movement with respect to the stationary component.
