Abstract: A skylight and roof assembly with at least a portion of the skylight adapted to be pivoted by a drive mechanism between open and closed positions with respect to an opening in the roof. At least one hinge is connected to the movable portion of the skylight and the fixed portion of the assembly to permit the pivotal movement. The hinge includes a first leg adapted to be mounted on the movble portion of the skylight in fixed position. The hinge includes a second leg adapted to be mounted on the non-movable portion of the skylight and roof assembly. A flange extends from the second leg and mating surfaces are on the first leg and the flange adapted to receive a coupling pin for pivotally interengaging the first and second leg with the first leg spaced from the second leg by the flange therebetween so that the movable portion of the skylight can be pivoted in a desired manner between the open and closed position.
