Abstract:
A garage door drive assembly for moving a linkage arm connected to a garage door to raise and lower the garage door, the assembly being adapted for shipping in a partially assembled condition in at least a box for on-site installation, the assembly comprising:a longitudinally-extending rail having laterally extending flanges extending therefrom; a carriage shaped to fit about the flanges thereby supporting the carriage for sliding motion along the rail; a drive mechanism movably mounted to the rail for longitudinal motion along the rail; an anchor coupled to the drive mechanism for movement with the drive mechanism; and a coupler having, 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; wherein 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 the coupler in their connected state; and wherein the detachable connection includes a biased clip connected to the coupler, the biased clip having a hook; and a clip opening in the carriage, the clip opening being positioned so that the hook is inserted into the clip opening upon proper engagement between the carriage and the coupler.
