BARRIER OPERATOR WITH RACK AND PINION DRIVE AND COUPLING ASSEMBLY FOR AN INTEGRATED DOOR AND OPERATOR

摘要

The barrier operator system, method and kit described herein contemplate theuse of arack and pinion drive mechanism which is mounted on tracks of the operatorsystem such thatthe pinion is positioned to ideally engage the rack which is coupled to thebarrier to move thebarrier along the tracks in both the upstream and downstream direction. Pre-positioning thepinion relative to the rack and using the rack and pinion drive as describedherein permitscoupling the rack and motor at any variety of points along the barrier to moveit. Further whenthe barrier is an over head door, such as a garage door, the door is connectedto the rack througha coupling assembly which connects the door to the rack without making thelatter connectionthrough the motor driving the pinion.
