摘要
The barrier operator system, method and kit described herein contemplate the use of a rack and pinion drive mechanism which is mounted on tracks of the operator system such that the pinion is positioned to ideally engage the rack which is coupled to the barrier to move the barrier along the tracks in both the upstream and downstream direction. Pre- positioning the pinion relative to the rack and using the rack and pinion drive as described herein permits coupling the rack and motor at any variety of points along the barrier to move it. Further when the barrier is an over head door, such as a garage door, the door is connected to the rack through a coupling assembly which connects the door to the rack without making the latter connection through the motor driving the pinion.
