In order to facilitate the opening of a floor door and to counteract the slamming which causes damage, the door leaves (1) which are pivotable about shaft bolts are connected to a holding frame (4) on the shaft (26) in an articulated manner by means of articulated arms (20) which are shifted forwards in relation to the shaft bolts, the articulated arms (20) being equipped with damping members which act as an opening aid. <IMAGE> |
