A curved track support is disclosed for a door, window, access door and the like which includes a curved track carrier having a curved track and a trunnion carrier having a trunnion for engaging the first track. Furthermore, the curved track carrier is provided with a second trunnion and the trunnion carrier is provided with a second curved track. Thus, the curved track support includes mutually opposite and reverse, positive guide structures. The mutually opposite placement of the trunnions and guide tracks stabilizes the curved track support and allows it to handle higher loads. At the same time, a defined rotation/sliding movement of the door is achieved by controlled displacement of the axis of rotation. Moreover, an exactly defined jam-free positioning of the door is achieved with substantially no play at any opening angle. The respectively opposite positioning of the trunnions and the curved tracks results in a positive guiding operation and provides for a large range of trunnion paths with respectively different geometry so that substantially any desired rotation/sliding movement of the door can be achieved by appropriately designing the curved tracks.
