Appl. No.:

09/505240

Inventors:

Christopher M. Valente - Lombard IL
James J. Fitzgibbon - Batavia IL
Ramon Tam - Chicago IL
Mark Siegler - Aurora IL
Martin Rathgeber - Chicago IL

Assignee:

The Chamberlain Group, Inc. - Elmhurst IL

International Classification:

E05F 1510

US Classification:

318468, 3185681

Abstract:

A method of programming a controller for a movable barrier operator includes enabling and disabling an input device within a predetermined period of time, a predetermined number of times. This sequence of short activations of an input device, such as a switch on a wall unit, puts the controller in a learn mode or a programmed state. Thereafter, the controller is responsive to learn any of the various routines that can be programmed for the movable barrier operator, such as transmitter code, limits of travel, force settings, and so on.

International Classification:

E05F 11/00

US Classification:

49199, 49322

Abstract:

A jack shaft garage door operator for opening and closing a movable garage door has a drive containing an electric motor. A rotatable jack shaft is connected to the drive unit to be driven thereby. A pull-up cable drum is connected to and driven by the jack shaft. A pull-up cable extends from the drum about which it is wound and connects to a bottom part of the garage door to raise the door. A pivoting arm is mounted near the jack shaft and provides tension to the cable. A shaft lock hub mounted on the jack shaft is engaged and locked by the arm if the tension in the cable drops. A stop is mounted on the garage door for engagement by the movable arm in the event that the door is opened without the cable being drawn in the cable drum.

Mark D. Siegler - Brookfield IL

Assignee:

The Chamberlain Group, Inc. - Elmhurst IL

International Classification:

F16H 718

US Classification:

74140

Abstract:

A chain guide is provided for the otherwise unsupported upper run of the endless roller chain of a motor-driven garage door operator. With the chain loop in a vertical plane, the chain guide takes the form of a trough having at its bottom an upstanding central ridge which supports the chain by its rollers and with the links clear of contact with the floor and sides of the trough. The chain guide is supported indirectly by the trackage of the door operator, being mounted upon the fixed rail spacer of one form and carried upon the movable trolley of the other.
