发明名称 Method of preventing persons from forgetting a door key and being locked out of a room
摘要 A method of reminding a person from locking themselves out of a room or dwelling comprises the steps of hanging a key on a door frame adjacent a door opening having a door hingedly mounted thereon, in such a position that when the door is swung open with respect to the door frame, the door will engage the key and dislodge the key from its means of support to cause it to fall to a floor surface adjacent the door opening. These steps alert the person of the presence of the key so as to remind the person to pick up and retain the key before allowing the door to close, thus preventing the person from being locked out of entry to the room without the key if the door automatically locks upon closing.
