<p>The invention relates to a device for indicating the direction of opening of doors using color codes based on the colors red and green. The color red is used to signal that the door, if it has leaves should be pulled, whilst if it is a sliding door or a door with automatically opening leaves, it indicates that the proximity sensor is on the other side from the user, and therefore will not open on the user's side. The color green indicates that the direction of opening is in the direction of forward movement, i.e. a door consisting of leaves should be pushed, whilst an automatic door, sliding, or leaf-type door will open, in accordance with the proximity of a person, on the same side as that from which that person is approaching. Thus, the user anticipates the functioning of series of doors, and the invention achieves a significant time-savings for persons as they pass through doorways, prevents accidents and overcomes the language barrier by using colors to indicate the way in which the doors operate.</p> |
