Abstract:
An electromechanical door supporting system for temporarily maintaining a door in an open position having: a) a housing with an electric motor in communication with a power source; b) a base plate sized to pass underneath a swinging door; c) the base plate extending away from the housing; d) the electric motor causing rotational movement in a rod extending from inside the housing, to outside the housing and over a surface of the base plate; e) a door supporting element extending 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 secure an opened door.
