Abstract
A garage door drive assembly for moving a linkage arm connected to a garage door, the assembly being adapted for shipping in a partially assembled condition in at least a box for on-site installation, the assembly has a longitudinally-extending rail with laterally extending flanges. The assembly also has a carriage shaped to fit about the flanges. A drive mechanism is movably mounted to the rail. An anchor is coupled to the drive mechanism. The assembly also has a coupler with a selectively releasable connection to the anchor, a connector pivotably connectable to the linkage arm, and a detachable connection enabling the coupler to be fixedly secured to and carried by the carriage. The rail and the carriage may be shipped to the installation site in a box having a smaller cross-sectional profile than would be required to accommodate the carriage and coupling in their connected state.
