Remotely controllable automatic door operator and closer

A door operator apparatus mountable to a door frame structure and a movable door to control movement between a closed position and an opened position, said operator apparatus remotely controllable, said operator apparatus comprising:

• a motor assembly having an output shaft, said motor mountable to one of the door and the door frame structure;
• a rotation reduction assembly including a first input shaft and a reduced second output shaft;
• a linkage device coupled to said reduced second output shaft, said linkage device mountable to either the door or the door frame structure to control movement of the door;
• a slip clutch assembly coupled between said output shaft and said first input shaft to transfer torque therebetween, to enable a manual operation of the door by causing said clutch assembly to slip, and to enable a remote operation of the door;
• and
• a controller unit coupled to said motor assembly to activate said operator apparatus to close the door in manual operation, and to control remote operation of said door operator apparatus to open and to close said door in response to at least one remote signal.

A method of remotely controlling a door using a door operator including a motor assembly having an output shaft, said motor mountable to one of the door and the door frame structure, and a linkage device mountable to either the door or the door frame the door frame structure to control movement of the door, a slip clutch assembly coupled between said output shaft and said linkage device to transfer torque therebetween, said method comprising:

• mounting the door operator apparatus between a door frame structure and a movable door to control door movement between a closed position and an opened position;
• sensing a position of the door from positions consisting of:
• a closed position, an open position, and an unknown position;
• receiving at least one remotely generated signal;
• enabling and disabling a remote operation of the door;
• evaluating a received signal, said position, and said enabling said remote operation using a controller unit coupled to said motor assembly to activate said motor to open and to close said door;
• and
• enabling a manual operation of the door with the application of a manual force applied to the door and causing a slip clutch assembly to slip.
