A hinge construction for joining panels of a foldable closure assembly, comprising a female hinge member including an elongated substantially hollow channel which defines in cross-section an inner concave surface extending along an arc of circle and a fulcrum element in a spaced apart relationship with the concave surface. A male hinge member is received in the elongated channel for pivotal movement about the fulcrum element. The male hinge member includes an arcuate member defining in crosssection a convex surface extending along an arc of a circle and being in sliding contact with the concave surface, the male hinge member further including a supporting leg projecting from the arcuate member and engaging the fulcrum element in a supporting contact, the concave and convex surfaces being in an eccentric relationship whereby during a pivotal movement between the hinge members the surfaces contact each other in a sliding relationship over a zone smaller than the area of either one of the convex or the concave surfaces. The invention also extends to a foldable closure assembly comprising a novel hinge.
