Abstract
Obstacle sensing apparatus for a pivotal door has a drive for operating the door between open and closed positions. Linkage is provided between the pivotal column which supports the door for swinging movement and a platform pivotally mounted on a fixed adjacent structure. When an obstacle is encountered the reactive force pivots the platform through the linkage and activates switches which reverse the drive. Elastic blocks keep the platform centered except when an obstacle is encountered.
