A hinge assembly and door closure assembly. The assembly generally includes fork members with slots to receive a connector and gears, where one or more pins pivotally couple the gears and connector to the fork members, and where the connector maintains the gears in meshing engagement through substantially 360 degrees of pivotal movement between the fork members. The closure assembly generally includes a rack and pinion, a biasing mechanism, a slider mechanism, and an arm pivotally coupled to the slider mechanism and the pinion, wherein the arm rotates the pinion in response to pivoting of the door, and where rotation of the pinion causes the rack to move against the force of biasing mechanism.
