Door operator assembly
First Claim
1. A door operator assembly for use with a door frame and a door wherein the door is rotatable about an axis of rotation passing through a door hinge connecting the door frame and the door, wherein the door operator assembly moves the door between an open position and a closed positon relative to the door frame and the door is manually movable between the closed positon and the open position by at least one of pushing on a pushing side of the door and pulling from a pulling side of the door, wherein the door operator assembly comprises:
- an operator unit operable to drive an arm linkage to move the door from the open position to the closed position, the operator unit mounted to the door on the pushing side thereof and the operator unit comprising an input drive unit and an output drive unit comprising an output shaft rotatable about a first axis;
the arm linkage having a first end and a second end, wherein the first end of the arm linkage is coupled to the output shaft and the second end of the arm linkage is mounted on a portion of the door frame;
wherein, as viewed along an axis of the door that is orthogonal to a longitudinal axis of the door, the operator unit is positioned on the door intermediate the door hinge and the portion of the door frame;
a motor having a drive shaft rotatable about a second axis parallel to the first axis, the drive shaft being able to rotate a sun gear about the first axis and the sun gear driving at least one planetary gear system and the at least one planetary gear system being operatively connected to the output shaft such that the input drive unit and the output drive unit are disposed adjacent one another;
a rechargeable power storage pack for powering the motor comprising at least one of (i) at least one rechargeable battery and (ii) one or more capacitors; and
a controller, operatively coupled to the motor, for monitoring a speed and a position of the door as the door is manually moved from the closed positon to the open position, wherein when the door is manually moved faster than a predeteimined speed from the closed position to the open position, the motor is used as a generator to charge the rechargeable power storage pack and the speed of the door is reduced.
