Abstract
A floor-mounted door lock which includes in a first preferred embodiment, a floor anchor mounted to the floor near a door threshold in the path of swing of a door and having an upward-standing anchor flange. An anchor wedge is fitted with a bottom slot for removably receiving the anchor flange and obstructing the opening swing of the door. In an alternative preferred embodiment, the floor anchor is provided with a flange opening and the anchor wedge has a downwardly-extending wedge flange for registration with the flange opening and mounting the anchor wedge in position to block opening of the door. In a third preferred embodiment for application to raised thresholds, a flat threshold plate is fitted with an engaging flange on one end for engaging the threshold outside of the door and an upward-standing anchor flange or slot located at the opposite end for interlocking with an anchor wedge to locate the anchor wedge in a position to block the opening swing of the door.
