The invention relates to a device for indicating the direction of opening of doors using colour codes based on the colours red and green. The colour 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 colour 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, 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-saving for persons as they pass through doorways, prevents accidents and overcomes the language barrier by using colours to indicate the way in which the doors operate.

L'invention concerne un indicateur du sens d'ouverture d'une porte à l'aide de codes de couleur basés sur les couleurs rouge et verte. La couleur rouge sert à signaler que la porte, si elle est battante, doit être tirée, tandis que si elle est coulissante ou battante mais automatique, elle indique que le capteur de proximité se trouve du côté contraire, et que la porte ne pourra donc pas s'ouvrir de ce côté. La couleur verte indique que le sens d'ouverture correspond au sens du passage, c'est-à-dire qu'une porte battante doit être poussée, tandis qu'une porte automatique, coulissante ou battante, s'ouvrira selon la proximité de la personne du côté correspondant. L'invention permet ainsi à un utilisateur d'anticiper le fonctionnement de portes consécutives, aux personnes passant par les portes de gagner beaucoup de temps de manière signaificative, d'éviter les accidents et de résoudre le problème de la barrière lingüistique grâce à l'utilisation des couleurs pour indiquer le mode de fonctionnement des portes.
