Abstract: A swinging-sliding door for use in interior doorways of buildings. The door mechanism includes first and second upper swing arms each having opposite inner and outer ends. The inner ends are rotatably mountable to first and second ends of the upper jamb member in the door frame for rotation in a substantially common horizontal plane between a closed position flush along the upper jamb member and an open position substantially perpendicular to the upper jamb member. The inner end of the second upper swing arm is mountable into substantially a corresponding intersection between the upper jamb member and a vertical jamb member. A slide having first and second ends is mounted in the upper channel of the door and so as to be aligned parallel with the upper jamb member. The slide has a length corresponding to the length of the upper channel of the door. The outer ends of said first and second swing arms are rotatably mounted respectively to said first and second ends of said slide.
