Abstract: There is disclosed a lift-and-slide handle assembly (10) which includes a drive shaft (28) operatively adapted to couple with a roller actuating assembly of a lift-and-slide roller carriage. The lift-and-slide handle assembly (10) includes an electronic drive assembly (30) operatively adapted to couple with the drive shaft (28) to apply torque to the drive shaft and a manual drive assembly (32) operatively adapted to couple with the drive shaft (28) to apply torque to the drive shaft (28). The lift-and-slide handle assembly (10) further includes an override coupling assembly (34) operatively adapted to decouple the electronic drive assembly (30) from the drive shaft (28) to couple the manual drive assembly (32) to the drive shaft (28).

Abstract: A driving system for an automatic sliding door includes a driver and a rack and pinion mechanism. The pinion is selectively attachable to the driver in a first position to cause sliding movement of the door in the first direction and in a second position to cause sliding movement of the door in the second direction. A device for indicating whether a driving system is suitable for driving a sliding door includes a first end, a region including one or more calibrations; and a second end. The first end is adapted to be pulled by a user. The second end is adapted to be selectively and detachably attached to one of the calibrations. The region is located between the first end and the second end.
