Abstract: A pivotable glazing structure for covering an opening comprising sheets forming sections. Each sheet having a bottom edge and a top edge and each sheet is supported by its tip or bottom edge to a first bearing rail mounted on a structure and an opposite edge is supported at one supporting point to a second bearing rail mounted on a structure. The sheets can be individually moved to an edge of the opening covered by the sheets on sheet supporting points and pivoted through 90 degrees on first sheet hinge pines which are positioned at supporting points in alignment with each other so as to expose an outwardfacing surface of the sheet. A second hinge pin of the sheet is provided with a latch for locking the second hinge pin in position as the sheet is being pivoted on hinge pins. The latch comprises a jutting member made of a flexible material and the jutting member is adapted to engage with a toothed portion attached to or formed integrally with the bearing rail.
