Device in door arrangements

摘要

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.
