Abstract

Automatic door protected by means of light barriers, which has a device voluntarily actuable by the passenger and making it impossible for the light to be reflected to the receiver. <IMAGE>

Description

Bei heute üblichen automatischen Türen werden diese vom Benützer durch einen elektrischen Kontakt, der den Öff­nungsmechanimus auslöst, geöffnet.In automatic doors that are common today, the user opens them by means of an electrical contact that triggers the opening mechanism.

Um ein ungewolltes Schließen der Tür zu verhindern, wenn sie gerade jemand durchschreitet, ist in der Türöffnung ein Lichtschranken angeordnet. Eine Lichtquelle sendet einen Lichtstrahl an eine an einen ihr gegenüberliegenden Seite angeordneten Empfänger, der den Einfall des Licht­strahles registriert und bei Unterbrechung des Lichtein­falles ein Schließen der Tür verhindert, bzw. wenn die Tür bereits im Schließen ist, diese wieder öffnet.To prevent the door from being closed accidentally when someone is walking through it, a light barrier is installed in the door opening. A light source sends a light beam to a receiver located on its opposite side, which registers the incidence of the light beam and prevents the door from closing when the light is interrupted, or opens the door again when the door is already closing.

Nachteilig an einer solchen Bauart ist, daß sowohl ein Mechanismus zum Öffnen durch den Benützer, als auch eine Öffnungseinrichtung für den Lichtschranken vorhanden sein muß.A disadvantage of such a design is that both a mechanism for opening by the user and an opening device for the light barriers must be available.

Unserer Erfindung liegt die Aufgabe zugrunde, diese bei­den Öffnungsmechanismen zu vereinen und dadurch die An­zahl der nötigen Einrichtungen zur Benützung einer auto­matischen Tür zu verringern.The object of our invention is to combine these two opening mechanisms and thereby to reduce the number of devices required to use an automatic door.

Erfindungsgemäß wird das so erreicht, daß sie eine vom Benützer willkürlich betätigbare Einrichtung aufweist, die die Reflexion des Lichtes zum Empfänger unmöglich macht. Somit wird die Lichtschrankensicherung auch zum bedarfsmäßigen Öffnen der Tür verwendet.According to the invention this is achieved in such a way that it has a device which can be operated arbitrarily by the user and which makes the reflection of the light to the receiver impossible. The light barrier protection is thus also used to open the door as required.

Erfindungsgemäß kann eine vorteilhafte Ausführung so er­folgen, daß die willkürlich betätigbare Einrichtung am Türblatt befestigt ist und einen Reflektor mit, in Licht­ strahleinfallsrichtung gesehen, vor diesem angeordneter verschieblicher oder verdrehbarer Abdeckung aufweist. Es ist aber auch möglich, statt einer Abdeckung einen ver­drehbaren Reflektor zu verwenden.According to the invention, an advantageous embodiment can take place in such a way that the arbitrarily operable device is attached to the door leaf and a reflector with, in light seen direction of incidence, has arranged in front of this movable or rotatable cover. However, it is also possible to use a rotatable reflector instead of a cover.

Die Bauweise eignet sich besonders für solche automati­sche Türen, bei denen die Öffnungsbetätigungstaste am Türblatt angeordnet ist, da keine Kabelverbindungen oder Schleifkontakte zwischen Türblatt und Türrahmen nötig sind.The design is particularly suitable for those automatic doors in which the opening actuation button is arranged on the door leaf, since no cable connections or sliding contacts between the door leaf and door frame are necessary.

Falls der Lichtschranken knapp über den Boden verlaufen soll, ist es ungünstig, die Konstruktion so auszuführen, daß die willkürlich betätigbare Einrichtung einen Auslö­ser aufweist, der in normaler Griffhöhe am Türblatt ange­ordnet ist und der Teil mit der Reflexionsverhinderung im Bereich zwischen Türöffnungsschalter und dem vom Türbe­nützer begangenen Boden angeordnet ist, wobei die Kraft­übertragung zwischen Auslöser und Reflexionsverhinde­rungseinrichtung durch ein Gestänge erfolgt.If the light barrier is to run just above the floor, it is unfavorable to construct the construction in such a way that the arbitrarily operable device has a trigger which is arranged at the normal handle height on the door leaf and the part with the reflection prevention in the area between the door opening switch and that of the door user floor is arranged, the power transmission between the trigger and reflection prevention device is carried out by a linkage.

Eine andere mögliche, vorteilhafte Ausführung ist so be­schaffen, daß Lichtsender und Empfänger des Lichtschran­kens gemeinsam am Türkasten in Höhe zwischen der Griff­höhe und dem begangenen Boden angeordnet sind, ein Um­lenkreflektor am Türblatt in gleicher Höhe wie der Licht­sender befestigt ist und der Auslöser gemeinsam mit der Reflexionsverhinderungseinrichtung in Griffhöhe am Tür­blatt befestigt ist.Another possible, advantageous embodiment is such that the light transmitter and receiver of the light barrier are arranged together on the door box at a height between the handle height and the floor being walked on, a deflection reflector is attached to the door leaf at the same height as the light transmitter, and the trigger is mounted together with the reflection prevention device is attached to the door leaf at handle height.

Der Lichtstrahl kann dabei im Rahmen des Türblattes oder in einer Verkleidung verlaufen und ist somit vor unge­wollten Unterbrechungen geschützt. Die Einrichtung kann außerdem als kompakte Einheit ausgeführt werden.The light beam can run in the frame of the door leaf or in a panel and is thus protected against unwanted interruptions. The device can also be designed as a compact unit.

Falls gewünscht ist, die Unterbrechung des Lichtschran­kens in verschiedenen Höhen zu ermöglichen, kann die Er­findung so gestaltet sein, daß der Lichtsender des Licht­schrankens am Türkasten in Höhe zwischen der Griffhöhe und dem begangenen Boden angeordnet ist, ein Umlenkre­flektor am Türblatt in gleicher Höhe wie der Lichtsender befestigt ist, der Auslöser mit dazugehöriger Reflexions­verhinderung in Griffhöhe angeordnet und der Empfänger in Höhe der Reflexionsverhinderung angebracht ist.If it is desired to enable the interruption of the light barrier at different heights, the invention can be designed so that the light transmitter of the light barrier is arranged on the door box at a height between the handle height and the floor being walked on, a deflection reflector on the door leaf at the same height as the light transmitter is attached, the trigger with the associated reflection prevention is located at handle height and the receiver is attached at the level of reflection prevention.

Ein Verfahren zum Betrieb einer solchen Tür, das die er­findungsgemäßen Vorteile ausnützt, kann so durchgeführt werden, daß zur Freigabe der Benützung der automatischen Tür der Lichtsender des Lichtschrankens eingeschaltet wird und ein, die Tür öffnen wollender durch Betätigen des Auslösers die Reflexion des Lichtstrahls verhindert, wodurch die Tür automatisch geöffnet wird.A method for operating such a door, which takes advantage of the advantages of the invention, can be carried out in such a way that the light transmitter of the light barrier is switched on in order to release the use of the automatic door and a reflection of the light beam is prevented by opening the door by actuating the trigger, which will automatically open the door.

Die Erfindung wird anhand der nachstehenden Zeichnungen erklärt.The invention is explained with reference to the drawings below.
