Public restroom is one of the most common basic facilities. It is not easy for the user to tell whether there already is someone inside. The Right-angle Rotating Door is a new product that changes the traditional pattern of using door by a right-angle structure. Push the door directly from outside to enter the room. The door is rotated to be closed and separated from the next room. The part without handle means the room is occupied. Push the door from inside to open it. One part of the door out means there is nobody in it. It is convenient for telling way of operating door and using state of the room, avoiding unnecessary tries.
