Abstract
L'invention concerne un dispositif de capteur pour une porte capable de détecter de façon non coûteuse et précise un obstacle dans une entrée de porte qui est ouverte et fermée par une porte coulissante. Un premier miroir de réflexion est disposé sur un côté de l'entrée de porte et un projecteur/récepteur de lumière est placé sur l'autre côté de l'entrée de porte avec l'entrée de porte entre eux. Le projecteur/récepteur de lumière a un second miroir de réflexion dirigé vers le premier miroir de réflexion, une section de projection de lumière placée au-dessus du second miroir de réflexion, et une section de réception de lumière placée au-dessous du second miroir de réflexion. Le projecteur/récepteur de lumière est fabriqué de telle sorte qu'un faisceau lumineux émis à partir de la section de projection de lumière est reçu par la section de réception de lumière après avoir été réfléchi de nombreuses fois par les premier et second miroirs de réflexion. Lorsque le faisceau lumineux émis à partir de la section de projection de lumière n'est pas reçu par la section de réception de lumière, le dispositif de capteur pour une porte détecte la présence d'un obstacle dans l'entrée de porte.
