Dabei ist der bzw. sind die Türflügel (2) über eine Türflügelanbindung (6) mit einem Linearantrieb, beispielsweise einem Spindelantrieb, verbunden. Um die Einklemmkraft zu begrenzen ist vorgesehen, dass zumindest eine der Türflügelanbindungen (6) mit dem Linearantrieb über eine Feder (12), bevorzugt eine Kompressionsfeder, verbunden ist, die den Türflügel (2) in Schließrichtung mit Kraft beaufschlagt.The invention relates to a device for protection at the main closing edge (15) in the closing end of a door (1) for trapped persons, animals or objects in sliding doors and sliding doors, especially of vehicles and especially of rail vehicles such as suburban trains or subways. In this case, the or the door leaves (2) via a door leaf connection (6) with a linear drive, such as a spindle drive connected. In order to limit the pinching force, it is provided that at least one of the door leaf connections (6) is connected to the linear drive via a spring (12), preferably a compression spring, which acts on the door leaf (2) in the closing direction.
Description
Die Erfindung betrifft eine Vorrichtung zum Schutz von eingeklemmten Personen, Tieren oder Gegenständen bei Schiebetüren und Schwenkschiebetüren, insbesondere von Fahrzeugen und ganz besonders von Schienenfahrzeugen wie S-Bahnen oder U Bahnen, an der Hauptschließkante im Schließendbereich der Türen, entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a device for the protection of trapped persons, animals or objects in sliding doors and sliding doors, especially of vehicles and especially of rail vehicles such as rapid-transit railways or subways, on the main closing edge in the closing end of the doors, according to the preamble of
Vorrichtungen und auch Steuerverfahren zur Bewegung von Türen, im Zusammenhang mit dem Problem des Einklemmens von Gegenständen, der Einfachheit halber wird im Folgenden nur von Gegenständen gesprochen, worunter auch Mensch und Tier zu subsummieren sind, an der Hauptschließkante im Schließendbereich der Türen, sind verschiedentlich bekannt, beispielsweise aus der
Diese Vorrichtungen haben sich bewährt und werden vielfach eingesetzt, doch besteht nach wie vor Bedarf an einer wesentlich einfacheren, daher auch kostengünstigeren, leichter zu wartenden und dennoch gleichermaßen zuverlässigen Lösung.These devices have proven themselves and are widely used, but there is still a need for a much simpler, therefore cheaper, easier to maintain and yet equally reliable solution.
Es ist Aufgabe der Erfindung, eine solche Lösung anzugeben.It is an object of the invention to provide such a solution.
Dies geschieht erfindungsgemäß durch die im Anspruch 1 im kennzeichnenden Teil angegebenen Merkmale; mit anderen Worten, bei einer Tür mit Spindelantrieb wird bei einem der Türflügel die Türflügelanbindung gegenüber der Spindelmutter mit Schiebesitz über eine Druckfeder, gesehen in Schließrichtung geführt. Wenn der Fingerschutz auf einen Gegenstand stößt, wird der Antrieb weiterbetätigt bis die Spindelmutter in der Schließendlage ist und die Verriegelung des Türantriebs erfolgen kann, der Türflügel selbst wird durch die Druckfeder nicht starr, nämlich mit der Schließkraft des Türantriebs, sondern nur mit der voreingestellten Federkraft und deren Zunahme durch die zunehmende Spannung der Feder, gegen das Hindernis gedrückt und durch diese Federkraft wird die Tür nach Entfernen des Hindernisses ebenfalls in ihre Schließendlage gebracht.This is done according to the invention by the features specified in
Bei Türen mit Linearantrieb wird die Erfindung mutatis mutandis angewandt, letztlich besteht sie aus der federnden Verbindung zwischen dem Antrieb (Mutter auf Spindel, Kolbenstange, beweglicher Teil eines linearen Elektromotors) einerseits und dem Türblatt andererseits.In doors with linear drive, the invention is mutatis mutandis applied, ultimately, it consists of the resilient connection between the drive (mother on spindle, piston rod, moving part of a linear electric motor) on the one hand and the door leaf on the other.
Gegenüber dem Stand der Technik hat dies den Vorteil, dass der Schließvorgang und das schlussendliche Verriegeln des Antriebes nicht verzögert wird, und dass dennoch das Einklemmen von Gegenständen nicht mit der vollen Schließkraft erfolgt, sondern mit der entsprechend voreingestellten begrenzten Federkraft. Damit wird das Aufdrücken der Tür zuverlässig verhindert, das Entfernen des eingeklemmten Gegenstandes erleichtert und es ist sichergestellt, dass nach dem Entfernen des eingeklemmten Gegenstandes auch der Türflügel ohne weitere Tätigkeit in die Schließendlage kommt.Compared to the prior art, this has the advantage that the closing process and the final locking of the drive is not delayed, and that still the jamming of objects does not take place with the full closing force, but with the corresponding preset spring force limited. Thus, the pressing of the door is reliably prevented, facilitates the removal of the trapped object and it is ensured that after removal of the trapped object and the door without any further activity comes in the Schließendlage.

Wie aus
Erfindungsgemäß wird nun die Türflügelanbindung 6 mit der Spindelmutter 11 über eine, bevorzugt vorgespannte, Feder 12, im dargestellten Ausführungsbeispiel eine Schraubenfeder, verbunden. Damit ist der axiale Abstand a' (= in Richtung der Spindelachse 13), zwischen der Spindelmutter 11 und der Türflügelanbindung 6 variabel und nimmt, wie in
In
Auf der jeweils rechten Seite der
Die Funktionsweise ist nun Folgende: Selbst, wenn ähnlich wie in
Die Erfindung kann natürlich mit allen Schutz- und Sicherheitsvorrichtungen kombiniert werden, im Stand der Technik, beispielsweise für das Aufprallen der Türen auf Hindernissen weit außerhalb des Schließendbereiches, bekannt sind. Es können, wie in
In diesem Zusammenhang soll noch darauf hingewiesen werden, dass die axiale Erstreckung der Hindernisse für deren Behandlung sich die Erfindung eignet im Bereich bis zu einigen Zentimetern liegt. Als Grenze nach oben für den maximalen Abstand A ist die Sicherheit gegen das vollständige durch den gebildeten Schlitz im Bereich der Hauptschließkante treten von größeren Gegenständen oder gar Kindern anzusehen; als Grenze nach unten die Notwendigkeit, zumindest die empfindlichen Körperteile, insbesondere die Finger und Hände, gegen das Auftreten der eigentlichen Schließkraft zu schützen. Damit kommt man auf eine Untergrenze von a ∼ 3 cm und eine Obergrenze von A ∼ 12 cm, bei besonders voluminösen Fingerschutzgummis kann A auch merklich kleiner sein, beim Fehlen derartiger Fingerschutzgummis auch merklich größer.In this context, it should be noted that the axial extent of the obstacles to their treatment, the invention is suitable in the range up to a few centimeters. The limit upwards for the maximum distance A is the security against the complete passage through the formed slot in the area of the main closing edge of larger objects or even children; as a limit down the need to protect at least the sensitive body parts, especially the fingers and hands, against the occurrence of the actual closing force. Thus, one comes to a lower limit of a ~ 3 cm and an upper limit of A ~ 12 cm, with particularly voluminous finger protectors A can also be noticeably smaller, in the absence of such finger protectors also noticeably larger.
