ABSTRACT:
A garage door operator is provided which includes a flexible, elongated tape within a relatively rigid, elongated guide rail mounted in a garage. The tape has first and second runs longitudinally disposed in first and second guide channels in the guide rail. A motor is connected to drive a drive wheel with the tape wrapped around a part of the drive wheel and having a positive drive engagement therewith. A carriage is longitudinally guided on the guide rail and is connected both to the tape for movement therewith and by a link to a garage door for opening and closing movements of the door. The guide rail may be cut into sections for a shorter shipping package, and the tape coiled in a loop during shipment but then disposed within the guide channels during operation, the guide rail being spliced into one long, continuous assembly for use in the garage. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
