Abstract: In accordance with the invention a device in door arrangements is provided comprising a plurality of door panels which by hinge means are hingedly interconnected in sequence to pivot axes. The door panels are arranged to be guided by rollers arranged between guide tracks and the door panels for guided movement of said panels along the guide tracks extending along the intended path of movement of the door. The pivot axes of each hinge means is portioned between the side walls of contacting door panels. The hinge means hingedly interconnecting said contacting door panels comprise a convex member forming part of one of said contacting door panels and a concave member forming part of the other one of said contacting door panels. The members extend along the edges of the corresponding contacting door panels with their axes coinciding with pivot axis. The members form a bearing face, and the convex member is a separate component.

Abstract: A device in door arrangements includes a plurality of door panels hingedly interconnected to pivot about respective pivot axes. The pivot axes are positioned Between the side walls of contacting door panels. The hinge includes a convex member and a concave member, the concave member forming part of the other door panel. These two members extend along the edges of the corresponding door panels, coinciding with the pivot axis, with each member collectively forming a bearing face. Each door panel has a main profile extending uninterrupted over the entire cross section, and the edge of the door panel exhibits a curved section extending in the thickness direction. Further, each door panel has rigidifying portions arranged in the edge area.
