Abstract: A swinging screen door and associated frame are provided for coupling to a doorway of a structure such as a house. Hinges are provided which pivotably connect the doors to the frame in a fashion allowing the doors to pivot inward through the doorway and outward away from the doorway. The hinge includes a knuckle joint between the frame and a bottom of each door. A knuckle and recess of the knuckle joint are provided with a complemental form to cause the knuckle joint to bias the door toward a closed position. A ramp and wing combination in the knuckle joint cause the door to be elevated when moved away from the closed position so that the door can more easily clear obstacles on the floor adjacent the doorway. A recoil joint axially aligned with the knuckle joint holds a top of the door relative to the frame.
