Automatic lock-unlock door safety control

A method of automatically and temporarily maintaining a swinging door in an open position comprising:

• a) providing an electromechanical door supporting system for temporarily maintaining a door in an open position having:
• a) a housing containing an electric motor in communication with a power source;
• b) a base plate configured to pass underneath a swinging door;
• c) the base plate extending away from the housing in a first direction;
• the electric motor comprising a drive rod operatively connected to a lever segment, the lever segment connected to the housing and to an extended rod, operation of the electric motor causing rotational movement in the extended rod extending from inside the housing, to outside the housing and over a surface of the base plate, wherein the electric motor causing rotational movement creates a tension in a biasing spring within the housing, with tension counter to a direction of rotation of the extended rod in its rotated position causing biasing tension against the lever segment engaged with the drive rod;
• e) a door supporting element extending approximately perpendicular to the extended rod;
• and
• f) the door supporting element being attached to the extended rod at a proximal location and extending over the surface of the base plate to a distal end so that rotation of the extended rod causes the distal end of the door supporting element to elevate above the base plate to provide a supporting area between the door supporting element and the housing;
• the method including activating the electric motor to cause the rotational movement in an extended rod, tension or force from the electric motor at least partially maintaining the extended rod to remain in a rotated position in which the distal end of the door supporting element maintains the door in an open position.
