Door leaf device for opening and closing e.g. windows at casement in vertical position, has door leaf axes integrated to toothed sectors meshed on control racks, where assembly of sectors, door leaf axes and shuttles is laterally displaced

摘要

The device has a frame (1) provided with guiding profiles (2) in which shuttles (6) are slid. The shuttles have a bore in which door leaf axes (4) are guided by rolling and stopped. The axes are integrated to toothed sectors (5) that are meshed on control racks (3) fixed on a chassis. The control racks are detachably fixed on a part of the frame. Assembly of the toothed sectors, door leaf axes and the shuttles is laterally displaced in the guiding profiles by pushing a side of a door leaf and pulling another side of the door leaf.
