ABSTRACT:
The present invention relates to a door stop mechanism to be used as a child safety device. The door stop mechanism of the invention is for a door with a rotating door opening mechanism and a door jamb. The invention includes a blocking element, a flexible positioning member and an attachment hook member integrally joined to form a single molded structure. The door stop mechanism of the invention is attached to the rotating shaft of a door opening mechanism, such that the door stop mechanism will rotate in direct relation to the rotation of the door opening mechanism. In its closed position, the door stop mechanism rests across the edge of the door to prevent the door from completely closing. To close the door, the door opening mechanism must be rotated and held in this rotated position while closing the door. When the door opening mechanism is rotated, the blocking element of the present invention is moved away from the door edge which allows the door to be closed. Since the door opening mechanism must be held in a rotated position, the door stop mechanism of the invention prevents the door from being unintentionally shut by a small child, or other person.
