Patent Primary Examiner
The door stopper is adhered to the front wing of the door that has been completely opened and the door is prevented to move from this point on. When the door is desired to be closed, the door is pulled gently by hand, the force applied by the door to the stopper tensions the pressure spring and the pressure spring forces the moveable head down to the floor, thereby enabling the door to pass over the stopper.
