A door stop is provided comprising a first vertical plate for mounting to a wall and second horizontal pivot plate affixed to and extending outwardly from the wall-mounting plate. A third elongated member is pivotally mounted at its inner end to the pivot plate and at its outer end extends outwardly to a normal position perpendicular to the wall for making contact with a swinging door. A means is associated with the pivot plate for releaseably locking the third member in its normal position. In use, the door stop remains in its normal position until the elongated tube is struck by an object, such as a vacuum cleaner or mop. The impact releases the third member from its locked position and allows it to swing about its pivot point on the pivot plate to an out of the way position substantially parallel to the wall.
