-25- A door arrangement for mounting in the opening of a building comprises an upper panel and a lower panel connected for pivotal movement about a horizontal axis at the junction therebetween with the upper panel mounted for pivotal movement about a horizontal axis at the top edge of the panel relative to the building. The door panel is opened by pulling the lower edge of the lower panel upwardly in guide tracks on respective sides of the door panels. The door is locked by a lever projecting from the door panel and engaging an abutment on the ground so as to push the lower door panel in a direction to pivot the common axis of the door rearwardly into the plane of the opening.

Porte pour bâtiment, comprenant un panneau supérieur et un panneau inférieur joints de façon à pouvoir pivoter le long de l'axe horizontal les reliant. Le bord supérieur du panneau supérieur est conçu pour pivoter sur un axe horizontal par rapport au bâtiment. Pour ouvrir la porte, il suffit de tirer vers le haut sur le bord inférieur du panneau inférieur, de sorte qu'il se déplace dans des coulisses placées des deux côtés de la porte. Cette dernière est verrouillée au moyen d'un levier se prolongeant à partir du panneau inférieur et s'appuyant contre une butée sur le sol, ce qui a pour effet de pousser le panneau inférieur dans une direction qui provoque le pivotement de l'axe commun des deux panneaux de la porte vers l'arrière par rapport au plan d'ouverture de la porte.
