The combination has a first hinge leaf with an integral plastic camming surface positioned eccentrically about the common axis, a second hinged leaf with an integral plastic cam follower surface positioned about the common axis to engage the camming surface with increasing friction as the camming surface is cammed thereagainst, and structures for increasing the frictional engagement between the camming surface and cam follower surface in response to weight added to either of the hinged leafs to control the rate at which the leafs rotate relative to each other.
