Abstract: The mount is installed to the top horizontal segment of the door frame. The swing hangs from the mount by at least two cords. The mount includes two U-shape clamp frames, each having a first leg engaging vertical walls on opposite sides of the door frame top segment, and a second leg telescopically engaged into one another. Reciprocating motion of the two clamps one relative to the other is controlled by an endless screw shaft, the shaft being actuated by a handle. A pair of tilt-controlling arms are provided about the web of the corresponding clamps, adjacent their telescopic legs, to engage the bottom edge of the door frame top segment so as to prevent mount tilt during swinging motion of the swing.
