Abstract
The door stop mechanism wedges beneath the door knob of a closed door and against the floor to prevent the door from being opened from the outside. An over-center effect of the mechanism assures a positive lock securing position and an angular slot arrangement provides a foldable rigid mechanism without the use of other pins or fixing devices.
