Abstract

A motor driven door assembly is provided, the motor driven door assembly includes a door frame, a motor assembly connected to the door frame and having a motor directly connected to a first portion of a door hinge, and a door connected to the door hinge. The door hinge includes a second portion supported by a bearing assembly that carries substantially all of the door'"'"'s weight, and the motor directly drives the door hinge to open or close the door.

Claims

1. A motor driven door assembly comprising:

a door frame;

a motor assembly connected to the door frame and having a motor directly connected to a first portion of a door hinge; and

a door connected to the door hinge, the door hinge having a second portion supported by a bearing assembly that carries substantially all of the door'"'"'s weight;

wherein the motor directly drives the door hinge to open and close the door.

2. The motor driven door assembly of claim 1, further comprising an access panel arranged adjacent to the door to conceal the motor assembly and door hinge during operation of the door.

3. The motor driven door assembly of claim 1, wherein the bearing assembly is mounted flush to a floor on which the motor driven door assembly is installed.

4. The motor driven door assembly of claim 1, wherein the door has a weight of up to about 200,000 lbs.

5. The motor driven door assembly of claim 1, wherein the door hinge has an axis of rotation that is aligned with an axis of rotation of a drive shaft of the motor.

6. The motor driven door assembly of claim 1, wherein the door hinge includes a bottom hinge and a separate top hinge.

7. The motor driven door assembly of claim 6, wherein the motor is connected to the bottom hinge.

8. The motor driven door assembly of claim 6, wherein the top hinge rotates about a bearing assembly mounted to a ceiling of the door frame.

9. The motor driven door assembly of claim 1, wherein the door has an inner core formed of modular shielding elements and an outer surface formed of removable modular panels.

10. The motor driven door assembly of claim 1, further comprising a user control system electrically connected to the motor assembly to control operation of the door.

11. The motor driven door assembly of claim 10, wherein the door includes a sensor configured to relay signals to the user control system.

12. The motor driven door assembly of claim 11, wherein the user control system comprises a display interface configured to receive user input information and display output information, the display interface being connected to a processor that receives signals from the sensor, records data to a memory, and controls the motor.

13. A motor driven door assembly for installation in an existing entryway, the motor driven door assembly comprising:

a motor having a drive shaft that rotates about a vertical axis;

a door having a hinge connected to the drive shaft;

a first access panel arranged adjacent to the door outside of the existing entryway; and

a second access panel arranged adjacent to the door inside of the existing entryway opposite from the first access panel,

wherein the first and second access panels are movable and conceal the motor and hinge during operation of the door.

14. The motor driven door assembly of claim 13, wherein the first access panel is rotatably connected to the door and configured to slide along an adjacent wall during operation of the door, and the second access panel is rotatably connected to an adjacent wall and configured to slide along the door during operation of the door.

15. The motor driven door assembly of claim 14, wherein the first and second access panels are connected to the door and the adjacent wall, respectively, by spring hinges.

16. A floor mounted motor driven door assembly comprising:

a door frame;

a motor assembly connected to the door frame, the motor assembly having a motor with a rotating drive shaft;

a door having a hinge directly connected to the rotating drive shaft;

a bearing assembly that supports a lower end of the hinge and is mounted flush with a floor on which the floor mounted motor driven door assembly is installed; and

a movable access panel arranged between and connected to one of the door and a side of the door frame to conceal the motor assembly and the hinge during operation of the door,

wherein the door is directly driven by the rotating drive shaft as the door pivots about the hinge between a closed position and an open position, without use of any intervening components between the rotating drive shaft and the hinge.
