摘要 A flag assembly includes a lateral projection at its lower end enabling flag raising by fingertip pressure. A spring biased rod includes an arm member contactable with the projection during door opening to automatically lower the flag. A link associated with the rod moves past the door hinge pin axis to lock the door open and also to close the door after initial manual door closing movement.
