A door operating assembly (100) for operating a sliding door leaf (101) driven by a drive unit (112) along a sliding door rail (110), said door operating assembly (100) comprising a door bracket (150) configured to position the door leaf (101) relative the rail (110), a drive member (170) adapted to be driven by the drive unit (112), and a lever arm (160) having one end (161) pivotally connected to the drive member (170) and a remote portion (167) pivotally connected to the door bracket (150) via a cam structure (194) such that the vertical position of the door leaf (101) relative the rail (110) varies when the lever arm (170) pivots.

A double door gate apparatus having a frame, a main gate and a secondary gate, where the apparatus includes the unique features of a) a latch apparatus between uppermost framework members of the main gate and secondary gate, b) the latch apparatus being weighted to return to a normally closed position, c) each of the main gate and secondary gates having an inverted U-shaped piece engaging the bottommost horizontal member such that each of the main and secondary gates need to be lifted prior to being opened and prior to being closed, and d) a pair of hand wheels on a common shaft that work together to space the double door gate apparatus a desired distance from a vertical surface such as a wall.

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).
