Abstract
A door system having a linkage assembly with a drive arm and an attendant arm coupled at the ends through a gear joint. The gear joint has drive teeth on an end of the drive arm and attendant teeth on an end of the attendant arm. The drive arm is coupled to a motor in the door system that is coupled to a door, or a door frame or a wall. The attendant arm is coupled to the opposite of the door, or the door frame or the wall to which the door system is coupled. When the door system is installed on the push side or the pull side of the door the drive arm and the attendant arm are parallel with the door and the upper door frame. During operation the motor transfers the torque from the motor through the gear joint to open the door.
Claims20
A door system comprising:
- a door system housing, wherein the door system is operatively coupled to a door, a door frame, or a wall;
- a motor located at least partially within the door system housing;
- a linkage assembly comprising:
- a drive arm having a distal drive end and a proximal drive end, wherein the proximal drive end has drive teeth;
- and
- an attendant arm having a distal attendant end and a proximal attendant end, wherein the proximal attendant end has attendant teeth;
- wherein the drive teeth and the attendant teeth are operatively coupled together in a gear joint to allow the transfer of torque from the drive teeth to the attendant teeth which moves the attendant arm and the drive arm with respect to each other;
- and
- wherein the distal drive end of the drive arm is operatively coupled to the motor and the distal attendant end of the attendant arm is operatively coupled to the door, the door frame, or the wall.
A door assembly, the door assembly comprising:
- a door frame;
- a door operatively coupled to the door frame;
- a door system operatively coupled to the door, the door frame, or a wall, wherein the door system comprises:
- a door system housing;
- a motor located at least partially within the door system housing;
- a linkage assembly comprising:
- a drive arm having a distal drive end and a proximal drive end, wherein the proximal drive end has drive teeth;
- and
- an attendant arm having a distal attendant end and a proximal attendant end, wherein the proximal attendant end has attendant teeth;
- wherein the drive teeth and the attendant teeth are operatively coupled together in a gear joint to allow the transfer of torque from the drive teeth to the attendant teeth which moves the attendant arm and the drive arm with respect to each other;
- and
- wherein the distal drive end of the drive arm is operatively coupled to the motor and the distal attendant end of the attendant arm is operatively coupled to the door, the door frame, or the wall.
A method of mounting a door system, wherein the door system comprises a door system housing, a motor located at least partially within the door system housing, and a linkage assembly comprising a drive arm having a distal drive end and a proximal drive end, wherein the proximal drive end has drive teeth and an attendant arm having a distal attendant end and a proximal attendant end, wherein the proximal attendant end has attendant teeth, and wherein the drive teeth and the attendant teeth are operatively coupled together in a gear joint to allow the transfer of torque from the drive teeth to the attendant teeth which moves the attendant arm and the drive arm with respect to each other, and wherein the distal drive end of the drive arm is operatively coupled to the motor, wherein the door system is operatively coupled to a door, or a door frame or a wall, and the distal attendant end of the attendant arm is operatively coupled to the other of the door, or the door frame or the wall, the method comprising:
- mounting the door housing to the door or the door frame or the wall;
- and
- mounting the distal attendant arm of the linkage assembly having the gear joint to the opposite of the door or the door frame or the wall.
A method of operating a door system, wherein the door system comprises a door system housing, a motor located at least partially within the door system housing, and a linkage assembly comprising a drive arm having a distal drive end and a proximal drive end, wherein the proximal drive end has drive teeth and an attendant arm having a distal attendant end and a proximal attendant end, wherein the proximal attendant end has attendant teeth, and wherein the drive teeth and the attendant teeth are operatively coupled together in a gear joint to allow the transfer of torque from the drive teeth to the attendant teeth which moves the attendant arm and the drive arm with respect to each other, and wherein the distal drive end of the drive arm is operatively coupled to the motor, wherein the door system is operatively coupled to a door, or a door frame or a wall, and the distal attendant end of the attendant arm is operatively coupled to the other of the door, or the door frame or the wall, the method comprising:
- activating the motor to provide a force;
- and
- transferring the force of the motor through the gear joint to open or close the door.
