A door is mounted within a doorway to be pivotal about a pivot axis disposed close to and along one of side surfaces of the doorway to selectively open and close the doorway. A guide roller protrudes toward the upper surface of the doorway from the upper edge of the door at a location remote from the location of the pivot axis when the door is closed. A guide rail extends along the length of the upper surface of the doorway for guiding the guide roller along the length of the upper surface of the doorway. The guide rail is pivotal about the pivot axis. Means is provided to disengageably engage the guide rail with the upper surface of the doorway.

Une porte est montée dans une entrée de porte de manière à pivoter autour d'un axe de pivotement placé à proximité et le long d'une des surfaces latérales de l'entrée de porte pour ouvrir et fermer sélectivement la porte. Un galet fait saillie vers la surface supérieure de l'entrée de porte depuis le bord supérieur de la porte en un point éloigné de l'emplacement de l'axe de pivotement quand la porte est fermée. Un rail de guidage s'étend le long de la surface supérieure de l'entrée de porte pour guider le galet le long de la surface supérieure de l'entrée de porte. Le rail de guidage peut pivoter autour de l'axe de pivotement. Un moyen est prévu pour mettre le rail de guidage en prise de façon réversible sur la surface supérieure de l'entrée de porte.
