ABSTRACT:
A remote controlled door brace for an entrance door with a doorknob in a building. The brace comprises a floor anchor mounted into the floor of the building, which is spaced away from the entrance door. A hanger engages with the doorknob on the interior side of the entrance door. A bar projects downwardly from the hanger. A motor is provided, while a structure is for securing the motor to a bottom end of the bar. An adjustable support extends between the motor and the interior side of the entrance door, so as to keep the motor at the proper angle away from the entrance door. A movable rod assembly extends from the motor to the floor anchor. A facility is for activating the motor on the exterior side of the entrance door, so as to operate the movable rod assembly to bear against the floor anchor and buttress the entrance door, to prevent an unauthorized person from jimmying open the entrance door and entering the building.
