ABSTRACT:
A door opener provides for remotely opening and closing both a multi-panel closure and an overhead door used on the same doorway. The apparatus is expected to be most widely used with garage doors that have external screened closures installed outside them. An auxiliary opener, which can be configured to operate with either a chain-type overhead door opener or a screw-type opener, takes its power from a primary door opener and operates the screen closure in synchronism with the overhead door. The opening system can be used with a single doorway, or with a set of multiple doorways that share a common screen closure. The various versions of the apparatus are configured to continue to allow manual operation of slidable screen panels, and to permit the screen closure to be either open or closed when the main overhead garage door is open.
