  • Portable remote controlled door closer
    Patent number: 6061964
    Abstract: A portable remotely controlled automatic door closing apparatus enables the door of a room or office to be closed from a remote location within the room or office by transmitting a signal to an actuator which exerts a force on the door to move it from an opened position to a closed position. The apparatus comprises a battery or AC powered motor which moves a lever arm into engagement with the door to rotate the door about its hinges from the open to the closed position. The apparatus is free standing and immobilized on the floor in a non-connected relationship thereto between an apparatus wall and the door in its open position. The apparatus is immobilized to prevent slipping by a floor-engaging mechanism, such as an adhesive, an anti-skid rubber material, or suction cups, or carpet engaging projections.
