  • the radiation source and the radiation sensor are arranged at one end of the security zone and jointly designed as a reflection radiation probe, which responds to radiation of the radiation source, which is reflected by a possible object in the security zone to the radiation sensor.
  • reflex radiation probes are also available in a very compact design inexpensive as a reflex light scanner on the market. They are easy to install and save space and reliable in their function. In the case of reflex radiation scanners, radiation is reflected by the object to be detected itself. Radiation transmitter and receiver are often housed parallel to each other in a common housing. Reflex radiation sensors are also available in one design as so-called reflex radiation sensors with background suppression. These work especially well when it comes to detecting dark objects against a light background. Reflex radiation probes suitable for range determination are sometimes referred to as reflection distance sensors or optical distance sensors. There are two basic principles of operation for which reflex radiation probes work.
  • a first functional principle is the principle of triangulation, according to which the button can switch or output an error message signal when radiation emitted by the radiation emitter is reflected back at certain angles and, accordingly, strikes certain areas of the radiation receiver of the reflex radiation probe.
  • the second operating principle is the transit time detection principle, according to which the button can switch or output an error message signal, if emitted by the radiation emitter radiation pulses within a certain time window to the radiation receiver of the reflective radiation probe be reflected back, wherein the duration of the radiation pulses is detected by measurement.

  • Suitable light sensors for detecting the reflected light are, for example, photodiodes, phototransistors or optionally photoresistors.
  • the responds preferably used reflex light sensors on light, which is reflected by the object to be detected in the surveillance area itself.
  • Photoelectric sensors whether disposable photoelectric sensors or reflex photoelectric sensors, are less suitable for the invention, since they require a greater amount of assembly work and their reliable and reproducible function depends on whether the light receiver or light reflector is clean at its light entry window or has dirt .
  • the fouling problem with light barriers is quite relevant for the considerations made here, since preferably the security zone to be monitored normally extends vertically from the upper end to the lower end of the relevant door and a light barrier element (transmitter, reflector or receiver) in the door threshold would be provided. However, this is a place prone to contamination, as it can easily be walked on with shoes by persons who pass through the door. This problem can easily be overcome with reflex radiation probes if the top door end is chosen as the installation location. Then there is no need to install components of the system on the floor or in the sill.
  • systems which use sound radiation, in particular ultrasound radiation, and which accordingly respond to sound reflected back from the object to be detected in the surveillance area could also be used as reflex radiation sensors.

  • One of the door leaves moves faster than the other door leaf, so that it comes in the door opening process to an increasingly larger overlap area of the two door leaves.
  • the two door leaves define a gap between them, which is sometimes referred to as a freewheeling gap.

  • this edge usually runs vertically.
  • the backup zone usually runs vertically.
  • the security zone may in preferred embodiments extend over a region of the vertical length of the respective door leaf or over the entire vertical door leaf length.
  • a reflex radiation probe should conveniently be located at the top of the door leaf moving slower in the direction of opening movement (in the telescoping sliding door) and / or close up to the frame portion behind which a door leaf moves during the door opening movement.
  • the reflex radiation probe is protected in such an installation position from being entered by users of the sliding door with shoes and thereby polluted.
  • the security zone can be set up more or less in the gap or outside close to the gap entrance.
  • Device now in a door opening a finger or other object in such a backup zone it reflects radiation from the transmitter of the reflex radiation sensor to the radiation receiver of the reflective radiation probe, upon detection of this reflected radiation, the security device signals the presence of an object in the security zone, whereupon the drive device is caused by the control device to interrupt a further displacement movement of the moving door leaf.
  • the detection of objects with appropriate means of the security zone can be done even before the column entrance and in particular contactless, a very fast response of the security device is possible when an object enters the security zone, which can be prevented that the object at all in the gap at the edge of the overlapping area. It is also not necessary that the object with the relevant door leaf or frame section comes into contact before the safety device responds. As soon as it penetrates the beam path of the reflex radiation probe, an object can be detected before it ever comes into contact with the sliding door. This also serves the faster response of the security system.

  • the two door leaves 3.5 have orthogonal to the shift planes E3, E5 a slight distance A from each other, so that they without mutual contact along the shift planes E3, E5 in the closed position according to Fig. 1a and in the open position according to Fig. 2a can be moved. Due to the different speeds of movement of the door leaves 3,5 it comes in an opening operation of the telescopic sliding door to an increasingly larger overlap O (ie to a - Seen in the direction orthogonal to the shift planes E3, E5 - increasingly large mutual overlap of the two leaves 3.5) with a vertical edge coinciding with the trailing in the direction of movement of the vertical edge 9 of the slower-moving door leaf 5. In so doing, the two door leaves 3, 5 define a narrow vertical gap 11 extending along the edge 9.

Description

Die Erfindung betrifft eine Schiebetür, insbesondere Aufzugschiebetür, mit einem Türrahmen und wenigstens einem ersten Türelement, welches relativ zu einem zweiten Türelement unter Bildung eines gemeinsamen Überlapps verschiebbar ist, einer elektrischen Antriebseinrichtung zur Ausübung einer das erste Türelement verschiebenden Kraft, einer Sicherungseinrichtung zum Unterbrechen einer etwaigen Verschiebebewegung des ersten Türelementes in einer bestimmten Bewegungsrichtung bei Eindringen eines Objektes in eine Sicherungszone, die sich an einem quer zur Bewegungsrichtung des ersten Türelementes verlaufenden Rand des Überlapps entlang dieses Randes erstreckt, und einer Steuereinrichtung zur Steuerung der elektrischen Antriebseinrichtung und der Sicherungseinrichtung, wobei die Sicherungseinrichtung Mittel zur Überwachung der Sicherungszone aufweist, und wobei die Steuereinrichtung dazu eingerichtet ist, die elektrische Antriebseinrichtung zum Unterbrechen einer etwaigen Verschiebebewegung des ersten Türelementes in der bestimmten Bewegungsrichtung zu veranlassen, wenn die Sicherungseinrichtung das Vorhandensein eines Objektes in der Sicherungszone signalisiert.The invention relates to a sliding door, in particular elevator sliding door, with a door frame and at least one first door element which is displaceable relative to a second door element to form a common overlap, an electric drive means for exercising a first door element shifting force, a safety device for interrupting any Moving movement of the first door element in a certain direction of movement upon penetration of an object in a security zone, the extends on a transverse to the direction of movement of the first door element edge of the overlap along this edge, and a control device for controlling the electric drive device and the safety device, wherein the safety device comprises means for monitoring the safety zone, and wherein the control device is adapted to the electrical Drive device for interrupting a possible sliding movement of the first door element in the particular direction of movement to cause when the safety device signals the presence of an object in the safety zone.

Schiebetüren der vorstehend erwähnten Bauart werden üblicherweise als automatisch öffnende und schließende Türen vorgesehen und betrieben. Sie werden häufig als Aufzugtüren eingesetzt, sei es als Aufzugkabinentüren oder Aufzugschachttüren. Man findet solche Schiebetüren oft auch im Eingangsbereich von Bürogebäuden, Kaufhäusern und sonstigen öffentlichen Gebäuden.Sliding doors of the type mentioned above are usually provided and operated as automatically opening and closing doors. They are often used as elevator doors, be it as elevator car doors or elevator shaft doors. One often finds such sliding doors also in the entrance area of office buildings, department stores and other public buildings.

Da bei einem automatischen Schiebetürbetrieb die bewegbaren Türelemente relativ zueinander motorisch bewegt werden, sind besondere Vorsichtsmaßnahmen erforderlich, um Unfälle und Beschädigungen von Personen und Gegenständen im Bewegungsbereich dieser Türelemente zu vermeiden.Since in an automatic sliding door operation, the movable door elements are moved by a motor relative to each other, special precautions are required to avoid accidents and damage to persons and objects in the range of motion of these door elements.

Als bewegbare Türelemente kommen insbesondere Türblätter in Frage, so dass sich die folgenden Betrachtungen vorwiegend auf Türblätter beziehen, wenn bewegbare Türelemente erwähnt werden. Der Vorgang des Notstopps bei Eindringen von Objekten in den Sicherungsbereich ist insbesondere in Bezug für den Türöffnungsvorgang relevant.As movable door elements are in particular door leaves in question, so that the following considerations mainly relate to door leaves when movable door elements are mentioned. The process of emergency stop when objects enter the security area is particularly relevant in relation to the door opening procedure.

Insbesondere Türblätter, welche aus Glasscheiben gebildet sind oder Glasscheibenfüllungen aufweisen, scheinen beliebte Objekte der Berührung mit Händen zu sein. Vor allem Kinder scheinen dazu zu neigen, die Glasscheibenflächen solcher Türblätter mit Fingern zu betasten. Bei einer solchen Fingerberührung eines in Türöffnungsrichtung bewegten Türblattes kann es passieren, dass die betreffenden Finger von dem Türblatt in Türöffnungsrichtung mitgeführt werden, bis sie an bzw. in den Spalt zwischen dem bewegten Türblatt und z.B. einem Türrahmenpfosten oder - im Falle einer Teleskoptür - z.B. in den Spalt zwischen den sich in Öffnungsrichtung unter Bildung eines Überlapps bewegenden Teleskoptürblättern geraten und dabei gequetscht werden. Ein solcher Spalt verläuft längs eines jeweiligen vertikalen Randes des gemeinsamen Überlapps zwischen Türblatt und Rahmen bzw. zwischen zwei Türblättern. Die Problematik des Einziehens von Fingern oder ganz allgemein von Objekten in den Spalt zwischen Türblatt und Rahmen bzw. zwischen zwei Türblättern einer Schiebetür wurde bereits von verschiedenen Türherstellern aufgegriffen, und es wurden verschiedene Lösungen vorgeschlagen, wie es zu verhindern ist, dass Finger oder ganz allgemein Gegenstände an oder in einen solchen Spalt geraten.In particular, door leaves which are formed of glass panes or have glass pane fillings appear to be popular objects of touch with hands. Especially children seem to tend to finger-touch the glass panel surfaces of such door leaves. In such a finger touch a door leaf moved in the door opening direction, it may happen that the respective fingers are carried by the door leaf in the door opening direction, until it or in the gap between the moving door leaf and eg a door frame post or - in the case of a telescope door - for example in the gap between the get advised in the opening direction to form an overlap moving telescope door leaves and thereby squeezed. Such a gap extends along a respective vertical edge of the common overlap between the door leaf and the frame or between two door leaves. The problem of pulling fingers or more generally objects into the gap between the door leaf and the frame or between two door leaves of a sliding door has already been taken up by various door manufacturers, and various solutions have been proposed, such as preventing fingers or more generally Objects get caught in or in such a gap.

So ist z.B. aus der DE 199 37 561 A1 eine gattungsgemäße Teleskopschiebetür mit wenigstens einem Paar von relativ zueinander verschiebbaren Türelementen, nämlich einem Türrahmen und einem oder mehreren Türblättern, bekannt, wobei sich die Türelemente zum Öffnen der Türe relativ zueinander verschieben und zwischen sich einen Freilaufspalt, also einen Spalt der vorstehend erläuterten Art, im gemeinsamen Überlappungsbereich begrenzen. Die bekannte Teleskopschiebetür weist eine Sicherungseinrichtung mit einer Überwachungseinrichtung auf, welche ein Vorhandensein oder/und Eindringen eines Gegenstandes in einer Sicherungszone überwacht, die sich an dem quer zur Bewegungsrichtung der Türelemente verlaufenden vertikalen Rand des gemeinsamen Überlapps entlang dieses Randes erstreckt. Unter der Kontrolle einer Steuereinrichtung beendet die Sicherungseinrichtung die Öffnungsbewegung der Teleskopschiebetür durch Stoppen des elektrischen Türantriebs, wenn die Überwachungseinrichtung ein Eindringen bzw. das Vorhandensein eines Objektes in der Sicherungszone durch ein entsprechendes Störungsmeldesignal signalisiert. Insbesondere bei Türblättern mit relativ großer Masse kann es bei solchen bekannten Teleskopschiebetüren passieren, dass bewegte Türblätter aufgrund ihrer Trägheit nicht sogleich bei Eindringen eines Objektes in die Sicherungszone stoppen, sondern noch geringfügig nachlaufen, nach dem der jeweilige Türantrieb die Notstoppanweisung erhalten hat und abgeschaltet wurde. Damit besteht ein Restrisiko dass dennoch ein Gegenstand in den Freilaufspalt gerät, obwohl die Sicherungseinrichtung sofort auf das betreffende Störungsmeldesignal der Überwachungseinrichtung reagiert hat.For example, from the DE 199 37 561 A1 a generic telescopic sliding door with at least a pair of relatively movable door elements, namely a door frame and one or more door leaves, known, with the door elements to open the door move relative to each other and between them a freewheeling gap, so a gap of the type described above, in limit common overlap area. The known telescopic sliding door has a safety device with a monitoring device which monitors the presence or / and penetration of an object in a safety zone which extends along the edge of the common overlap extending transversely to the direction of movement of the door elements along this edge. Under the control of a control device, the securing device terminates the opening movement of the telescopic sliding door by stopping the electric door drive, when the monitoring device signals an intrusion or the presence of an object in the security zone by a corresponding fault signal. Especially with door leaves with relatively large mass, it can in such known telescopic sliding doors happen that moving door leaves do not stop due to their inertia immediately upon the entry of an object in the security zone, but still lag behind, after the respective door drive has received the emergency stop instruction and has been turned off. Thus there is a residual risk that still an object gets into the freewheeling gap, although the safety device has responded immediately to the relevant fault signal of the monitoring device.

Die Sicherungseinrichtung der aus der DE 199 37 561 A1 bekannten Teleskopschiebetür umfasst als Überwachungseinrichtung eine im Wesentlichen mechanisch betätigbare Schlagleiste, die eine bewegbar oder verformbar am Türelement angeordnete Leiste umfasst, oder eine überwiegend elektronisch bzw. opto-elektronisch arbeitende Sensorleiste, die mindestens eine Einweg oder/und Zweiweg-Lichtschranke aufweist, ist. Die Überwachungseinrichtung ist gegenständlich an oder in dem Freilaufspalt am Rand des Überlappungsbereichs zwischen den relativ zueinander bewegten Türelementen angeordnet, das heißt im Beispielsfall an und längs einer Kante der Stirnseite eines Türelementes in der Überwachungszone, und zwar vorzugsweise an dem Türelement, dass beim Öffnen keinen oder einen geringeren Verschiebeweg zurückgelegt. Grundsätzlich wird dabei von dem Prinzip Gebrauch gemacht, dass bei Verformung oder Verschiebung der Schlagleiste durch einen darauf auftretenden Gegenstand ein Störmeldesignal ausgelöst wird. Eine solche Verformung oder Verschiebung der Schlagleiste wird in einigen Ausführungsbeispielen der DE 199 37 561 A1 optoelektronisch mittels Lichtschranken erfasst, die in Bewegungsrichtung der Türelemente ausgerichtet sind und ansprechen, wenn der oder die Senderlichtstrahlen nicht in einer vorbestimmten Weise den oder die Empfänger der betreffenden Lichtschranken erreichen, was z.B. bei einer Verformung oder Verschiebung der mechanisch betätigten Schlagleiste durch einen an der Sicherungszone in den Freilaufspalt eingreifenden Gegenstand erfolgt. Eine solche Sicherungseinrichtung ist nicht nur relativ aufwendig und schwierig zu installieren, sondern auch vergleichweise träge im Ansprechverhalten, so dass aus diesem Grunde die Gefahr besteht, dass ein Gegenstand bereits in den Freilaufspalt eindringen kann, bevor das Sicherungssystem die Türbewegung stoppen kann.The safety device of the DE 199 37 561 A1 known telescopic sliding door comprises as a monitoring device a substantially mechanically operable blow bar, which comprises a movably or deformably arranged on the door element strip, or a predominantly electronic or opto-electronically operating sensor strip having at least one disposable and / or two-way light barrier is. The monitoring device is objectively arranged on or in the freewheeling gap at the edge of the overlapping region between the relatively moving door elements, that is, in the example on and along an edge of the front side of a door element in the surveillance zone, preferably on the door element, that when opening no or covered a smaller displacement. In principle, use is made of the principle that upon deformation or displacement of the blow bar by an object occurring thereon, a fault message signal is triggered. Such deformation or displacement of the blow bar is in some embodiments of the DE 199 37 561 A1 opto-electronically detected by means of light barriers, which are aligned in the direction of movement of the door elements and respond when the transmitter or the light beams do not reach the receiver or the receiver of the respective light barriers in a predetermined manner, such as in a deformation or displacement of the mechanically operated blow bar by one at the security zone takes place in the freewheeling gap engaging object. Such a security device is not only relatively expensive and difficult to install, but also comparatively sluggish in response, so that for this reason the There is a risk that an object may already penetrate into the freewheeling gap before the securing system can stop the door movement.

Weitere Türsysteme mit Sicherungseinrichtungen zur Unterbindung des Eindringens von Objekten in den Freilaufspalt im Überlappungsbereich zwischen zwei relativ zueinander unter Bildung des Überlappungsbereiches bewegten Türelementen, nämlich zwischen einem bewegten Türblatt und einem weiteren Türelement, sei es ein Türblatt oder Türrahmenabschnitt, sind z.B. aus der EP 2 074 270 B1 und aus der DE 10 2004 053 820 B4 bekannt. Auch diese weiteren bekannten Türsysteme weisen als Überwachungseinrichtungen Schaltleisten bzw. mechanisch zu betätigende Schaltanordnungen auf, die auf ihre Verschiebung oder Deformation durch Gegenstände, die in den Freilaufspalt eingedrungen sind, ansprechen, um ein Störmeldesignal auszulösen, so dass daraufhin die Sicherungseinrichtung unter Kontrolle einer zugehörigen Steuereinrichtung den Türantrieb stoppt. Auch für diese bekannten Türsysteme gilt, dass die Sicherungseinrichtungen relativ aufwendig gestaltet sind und ein vergleichsweise träges Ansprechverhalten zeigen. Aus der EP 1 243 544 A2 ist ein ebenfalls ein Türsystem mit Sicherungseinrichtung bekannt.Other door systems with security devices to prevent the penetration of objects in the freewheeling gap in the overlapping area between two relative to each other to form the overlapping area moving door elements, namely between a moving door leaf and another door element, be it a door leaf or door frame section, are for example from EP 2 074 270 B1 and from the DE 10 2004 053 820 B4 known. These other known door systems have as monitoring devices switching strips or mechanically actuated switching arrangements, which respond to their displacement or deformation by objects that have penetrated into the freewheeling gap to trigger a fault message signal, so that then the securing device under control of an associated control device the door drive stops. For these known door systems applies that the security devices are designed relatively expensive and show a relatively sluggish response. From the EP 1 243 544 A2 is also a door system with safety device known.

Aus der EP 2 332 876 A1 ist eine automatische Schiebetür entsprechend dem Oberbegriff des Anspruchs 1 bekannt mit zwei separaten und sich beim Schließen aufeinander zu bewegenden Türelementen bekannt, bei der bei Erfassung eines Hindernisse während eines Schließvorgangs beider Türelemente der Schließvorgang in einen Öffnungsvorgang jeweils beider Türelemente umgeändert wird. Dies ist jedoch auf Schiebetüren mit einem Überlapp zwischen einem ersten und zweiten Türelement nicht anwendbar, da beispielsweise ein bereits im Überlappbereich befindliches Objekt oder ein dort befindlicher Finger durch den Schließvorgang eingeklemmt werden könnte bzw. eventuell schon eingeklemmt ist und durch den Schließvorgang weiter beschädigt bzw. verletzt werden könnte.From the EP 2 332 876 A1 an automatic sliding door according to the preamble of claim 1 is known with two separate and closing each other to be moved door elements, in which upon detection of an obstacle during a closing operation of both door elements of the closing operation is changed into an opening operation of both door elements. However, this is not applicable to sliding doors with an overlap between a first and second door element, since, for example, an object already in the overlap area or a finger located there could be pinched by the closing operation or possibly already jammed and further damaged by the closing process or could be hurt.

Aufgabe der vorliegenden Erfindung ist es, derartige Nachteile bekannter automatischer Schiebetüren zu überwinden und Möglichkeiten aufzuzeigen, die Erfassung des Vorhandenseins oder/und des Eindringens eines Objektes an bzw. in den Spalt im Überlappungsbereich zweier relativ zueinander unter Bildung des Überlappungsbereiches bewegter und quer zu der Bewegungsrichtung hintereinander und mit geringem Abstand voneinander positionierter Türelemente bei automatischen Schiebetüren dahingehend zu verbessern, dass die Sicherungseinrichtungen rasches Ansprechverhalten zeigen, zuverlässig funktionieren und insbesondere einfach und sicher zu installieren sind. Vorzugsweise sollten die Überwachungseinrichtungen der Sicherungseinrichtungen ferner einen kompakten Aufbau aufweisen und nicht beschädigungsanfällig sein.The object of the present invention is to overcome such disadvantages of known automatic sliding doors and to show ways of detecting the presence or / and penetration of an object into or into the gap in the overlapping area of two relative to one another to form the overlapping area and transverse to the direction of movement successively and with little distance from each other positioned door elements in automatic sliding doors to improve in that the security devices show rapid response, work reliably and in particular are easy and safe to install. Preferably, the monitoring devices of the safety devices should also have a compact design and not susceptible to damage.

Ein Hauptanwendungsbereich der Erfindung sind automatische Aufzugschiebetüren, insbesondere Teleskopschiebetüren, wenngleich die Erfindung nicht darauf beschränkt sein soll.A major field of application of the invention is automatic elevator sliding doors, especially telescoping sliding doors, although the invention is not intended to be so limited.

Bewegbare Türblätter einer automatischen Schiebetür können eine relativ große Masse und damit auch eine relativ große Massenträgheit aufweisen, was sich beim Notstoppvorgang, also dem Vorgang der Unterbrechung der Verschiebebewegung eines betreffenden Türblattes bei Eindringen eines Objektes in die Sicherungszone nachteilig auswirken kann. So wurde es bei einigen automatischen Schiebetüren nach dem Stand der Technik beobachtet, dass Türblätter nicht sogleich mit Wegnahme der elektrischen Antriebsenergie in den mechanischen Stoppzustand übergegangen sind, sondern sich aufgrund ihrer Massenträgheit noch geringfügig weiterbewegt haben. Dieser Nachlauf des betreffenden Türblattes konnte ausreichen, um etwaige Objekte in den Freilaufspalt im Überlappungsbereich zwischen dem Türblatt und dem betreffenden anderen Türelement eindringen zu lassen und dabei Quetschungen zu verursachen. Auch dieser Effekt ist Ergebnis eines nicht ausreichend schnellen Ansprechverhaltens oder Reaktionsverhaltens des Sicherungssystems der Schiebetür.Movable door leaves an automatic sliding door can have a relatively large mass and thus a relatively large inertia, which can adversely affect the emergency stop process, ie the process of interrupting the sliding movement of a respective door leaf when an object enters the security zone. Thus, it has been observed in some prior art automatic sliding doors that door leaves have not immediately transitioned to the mechanical stop state upon removal of the electric drive energy, but have continued to move slightly due to their inertia. This caster of the relevant door leaf could be sufficient to allow any objects to penetrate into the freewheeling gap in the overlapping region between the door leaf and the respective other door element and thereby cause bruising. Also, this effect is the result of not sufficiently fast response or reaction behavior of the safety system of the sliding door.

Hier setzt die vorliegende Erfindung an. Erfindungsgemäß wird eine Schiebetür, insbesondere automatische Aufzugschiebetür, vorgeschlagen, die einen Türrahmen und wenigstens ein erstes Türelement aufweist, welches relativ zu einem zweiten Türelement unter Bildung eines gemeinsamen Überlapps verschiebbar ist, und welche ferner eine elektrischen Antriebseinrichtung zur Ausübung einer das erste Türelement verschiebenden Kraft, eine Sicherungseinrichtung zum Unterbrechen einer etwaigen Verschiebebewegung des ersten Türelementes in einer bestimmten Bewegungsrichtung bei Eindringen eines Objektes in eine Sicherungszone, die sich an einem quer zur Bewegungsrichtung des ersten Türelementes verlaufenden Rand des Überlapps entlang dieses Randes erstreckt, und eine Steuereinrichtung zur Steuerung der elektrischen Antriebseinrichtung und der Sicherungseinrichtung umfasst, wobei die Sicherungseinrichtung Mittel zur Überwachung der Sicherungszone aufweist, und wobei die Steuereinrichtung dazu eingerichtet ist, die elektrische Antriebseinrichtung zum Unterbrechen einer etwaigen Verschiebebewegung des ersten Türelementes in der bestimmten Bewegungsrichtung zu veranlassen, wenn die Sicherungseinrichtung das Vorhandensein eines Objektes in der Sicherungszone signalisiert. Erfindungsgemäß ist die Steuereinrichtung dazu eingerichtet, die elektrische Antriebseinrichtung zur Ausübung einer aktiven Kraft auf das Türelement zu veranlassen, die der Kraft entgegen- gerichtet ist, welche das Türelement zur Verschiebung in der bestimmten Bewegungsrichtung veranlasst hat, wenn bei einer solchen Verschiebung des ersten Türelementes in die bestimmte Bewegungsrichtung die Sicherungseinrichtung das Vorhandensein eines Objektes in der Sicherungszone signalisiert. Bei der bestimmten Bewegungsrichtung handelt es sich normalerweise um die Türöffnungsrichtung.This is where the present invention begins. According to the invention, a sliding door, in particular an automatic elevator sliding door, is proposed, which has a door frame and at least one first door element which is displaceable relative to a second door element to form a common overlap, and which further comprises an electric drive device for exerting a force displacing the first door element, a safety device for interrupting a possible displacement movement of the first door element in a certain direction of movement upon penetration of an object into a safety zone extending at a transverse to the direction of movement of the first door element edge of the overlap along this edge, and a control device for controlling the electric drive device and the safety device comprises, wherein the safety device comprises means for monitoring the safety zone, and wherein the control device is adapted to the electrical Drive device for interrupting a possible sliding movement of the first door element in the particular direction of movement to cause when the safety device signals the presence of an object in the safety zone. According to the invention, the control device is set up to cause the electric drive device to exert an active force on the door element, which is opposite to the force which caused the door element to shift in the determined direction of movement, if such a displacement of the first door element in FIG the particular direction of movement signals the safety device the presence of an object in the safety zone. The particular direction of movement is usually the door opening direction.

Grundgedanke und wesentliches Merkmal der Erfindung ist es, unmittelbar nach Feststellung des Vorhandenseins oder Eindringens eines Objektes in die Sicherungszone eine einer Trägheitsbewegung des betreffenden Türblattes entgegengesetzte Kraft zu erzeugen und kurzzeitig auf das Türblatt auszuüben und so einen möglichst sofortigen Stopp des Türblattes oder gar eine geringfügige Zurückbewegung des Türblattes hervorzurufen.The basic idea and essential feature of the invention is, immediately after detecting the presence or penetration of an object in the security zone, to generate an inertial movement of the relevant door leaf and to exert short-term impact on the door leaf and to cause as immediate as possible a stop of the door leaf or even a slight return movement of the door leaf.

Die Gegenkraft wird durch entsprechende Ansteuerung eines Antriebselektromotors der Steuereinrichtung mit einem Impuls elektrischer Energie (" Schubumkehrimpuls") erzeugt, um eine Antriebsumkehr bzw. eine Überwindung des Trägheitsnachlaufs des Antriebssystems hervorzurufen. Dabei kann gemäß einer Variante der Erfindung, die maximal im Antriebssystem verfügbare elektrische Antriebsenergie während des Schubumkehrimpulses für den Motor bereitgestellt werden.The counterforce is generated by appropriate driving of a drive motor of the controller with a pulse of electrical energy ("thrust reverser pulse") to cause drive reversal or overcoming of the inertia tracking of the drive system. In this case, according to a variant of the invention, the maximum available in the drive system electric drive energy can be provided during the thrust reverser pulse for the engine.

Erfindungsgemäß ist die Steuereinrichtung dazu in der Lage, die Zeitdauer des Impulses elektrischer Energie zur Erzeugung der entgegengesetzt gerichteten Kraft von der aktuellen Verschiebeposition oder/und der aktuellen Verschiebegeschwindigkeit des ersten Türelementes bei dessen Verschiebung in der bestimmten Bewegungsrichtung festzulegen.According to the invention, the control device is able to set the duration of the pulse of electrical energy for generating the oppositely directed force from the current displacement position and / or the current displacement speed of the first door element during its displacement in the determined direction of movement.

Vorzugsweise hat der Impuls elektrischer Energie eine Zeitdauer im Bereich von 10 ms - 500 ms, vorzugsweise in einem Bereich von 50 ms - 250 ms.Preferably, the pulse of electrical energy has a duration in the range of 10 ms - 500 ms, preferably in a range of 50 ms - 250 ms.

Vorzugsweise ist das erste Türelement ein Türblatt und das zweite Türelement ein Türrahmenabschnitt oder ein weiteres Türblatt einer Teleskopschiebetür.Preferably, the first door element is a door leaf and the second door element is a door frame section or another door leaf of a telescopic sliding door.

Vorzugsweise umfasst zumindest das erste Türelement eine Glasscheibe oder ist aus einer solchen gebildet.Preferably, at least the first door element comprises or is formed from a glass pane.

Bei der Schiebetür kann es sich z.B. um eine Aufzugtür, insbesondere einer Teleskopschiebetür einer Aufzugkabine oder eines Aufzugschachtes handeln.The sliding door can be, for example, an elevator door, in particular a telescopic sliding door of an elevator car or an elevator shaft.

Bevorzugt sind die Strahlungsquelle und der Strahlungssensor an einem Ende der Sicherungszone angeordnet und gemeinsam als Reflex-Strahlungstaster ausgebildet, der auf Strahlung der Strahlungsquelle anspricht, die von einem etwaigen Objekt in der Sicherungszone zum Strahlungssensor reflektiert wird.Preferably, the radiation source and the radiation sensor are arranged at one end of the security zone and jointly designed as a reflection radiation probe, which responds to radiation of the radiation source, which is reflected by a possible object in the security zone to the radiation sensor.

Derartige Reflex-Strahlungstaster sind auch in sehr kompakter Bauform preiswert als Reflex-Lichttaster am Fachmarkt erhältlich. Sie sind einfach und platzsparend zu montieren und in ihrer Funktion zuverlässig. Bei Reflex-Strahlungstastern wird Strahlung von dem zu detektierenden Objekt selbst zurückgeworfen. Strahlungssender und -empfänger sind häufig parallel zueinander in einem gemeinsamen Gehäuse untergebracht. Reflex-Strahlungstaster sind auch in einer Bauart als sogenannte Reflex-Strahlungstaster mit Hintergrundausblendung verfügbar. Diese funktionieren besonders zuverlässig, wenn es darum geht, dunkle Objekte vor hellem Hintergrund zu erkennen. Reflex-Strahlungstaster, die zur Entfernungsbestimmung geeignet sind, werden gelegentlich auch als Reflexions-Abstandssensoren oder optische Abstandssensoren bezeichnet. Es gibt zwei grundsätzliche Funktionsprinzipien, nach denen Reflex-Strahlungstaster arbeiten.Such reflex radiation probes are also available in a very compact design inexpensive as a reflex light scanner on the market. They are easy to install and save space and reliable in their function. In the case of reflex radiation scanners, radiation is reflected by the object to be detected itself. Radiation transmitter and receiver are often housed parallel to each other in a common housing. Reflex radiation sensors are also available in one design as so-called reflex radiation sensors with background suppression. These work especially well when it comes to detecting dark objects against a light background. Reflex radiation probes suitable for range determination are sometimes referred to as reflection distance sensors or optical distance sensors. There are two basic principles of operation for which reflex radiation probes work.

Ein erstes Funktionsprinzip ist das Triangulationsprinzip, gemäß welchem der Taster schalten bzw. ein Störmeldesignal ausgeben kann, wenn von dem Strahlungssender ausgesandte Strahlung unter bestimmten Winkeln zurückreflektiert wird und dementsprechend auf bestimmte Bereiche des Strahlungsempfängers des Reflex-Strahlungstasters trifft.A first functional principle is the principle of triangulation, according to which the button can switch or output an error message signal when radiation emitted by the radiation emitter is reflected back at certain angles and, accordingly, strikes certain areas of the radiation receiver of the reflex radiation probe.

Das zweite Funktionsprinzip ist das Laufzeiterfassungsprinzip, gemäß welchem der Taster schalten bzw. ein Störmeldesignal ausgeben kann, wenn von dem Strahlungssender ausgesandte Strahlungssimpulse innerhalb eines bestimmten Zeitfensters zum Strahlungsempfänger des Reflex-Strahlungstasters zurück reflektiert werden, wobei die Laufzeit der Strahlungssimpulse messtechnisch erfasst wird.The second operating principle is the transit time detection principle, according to which the button can switch or output an error message signal, if emitted by the radiation emitter radiation pulses within a certain time window to the radiation receiver of the reflective radiation probe be reflected back, wherein the duration of the radiation pulses is detected by measurement.

Für die Zwecke der vorliegenden Erfindung sind all die genannten Reflex-Strahlungstaster geeignet zur Ausbildung von bevorzugten Ausführungsformen der Erfindung. Besonders vorzugsweise kommen jedoch Reflex-Lichttaster in Frage, insbesondere Infrarotlicht-Strahlungstaster. Als Lichtquellen solcher Reflex-Lichtaster kommen insbesondere Leuchtdioden und vorzugsweise IR-Laserdioden in Frage. Auch kombinierte Lichtquellen, die z.B. sichtbares Licht und Infrarotlicht entlang desselben optischen Weges emittieren können, kommen in Frage, wobei das sichtbare Licht das Justieren des Sensorsystems bzw. der Überwachungseinrichtung aufgrund des sichtbaren Lichtflecks erleichtert und das Infrarotlicht als eigentliches Meßlicht des Reflex-Lichttasters dient. Als Lichtsensoren zur Erfassung des reflektierten Lichtes kommen z.B. Fotodioden, Fototransistoren oder ggf. Fotowiderstände in Frage. Im Unterschied zu herkömmlichen Reflex-Lichtschranken, die einen Lichtsender und Lichtempfänger auf einer Seite der Überwachungsstrecke und einen Lichtreflektor auf der entgegengesetzten Seite der Überwachungsstrecke aufweisen und auf eine Unterbrechung des Lichtstrahls auf dessen Weg vom Lichtsender zum Lichtreflektor und vom Lichtreflektor zum Lichtempfänger anspricht, reagiert der bevorzugt genutzte Reflex-Lichttaster auf Licht, das vom zu detektierenden Objekt im Überwachungsbereich selbst zurückgeworfen wird. Lichtschranken, seien es Einweg-Lichtschranken oder Reflex-Lichtschranken, kommen für die Erfindung weniger in Frage, da sie einen größeren Montageaufwand bedeuten und ihre zuverlässige und reproduzierbare Funktion davon abhängig ist, ob der Lichtempfänger bzw. Lichtreflektor an seinen Lichteintrittsfenster sauber ist oder Verschmutzungen aufweist. Das Verschmutzungsproblem bei Lichtschranken ist für die hier gemachten Überlegungen durchaus relevant, da bevorzugt die zu überwachende Sicherungszone normalerweise vertikal vom oberen Ende zum unteren Ende der betreffenden Tür verläuft und ein Lichtschrankenelement (Sender, Reflektor oder Empfänger) in der Türschwelle vorzusehen wäre. Dies ist jedoch ein verschmutzungsanfälliger Ort, da er von Personen, die Tür durchschreiten, ohne weiteres mit Schuhen betreten werden können. Dieses Problem kann mit Reflex-Strahlungstastern leicht überwunden werden, wenn als Installationsort das obere Türende gewählt wird. Dann besteht keine Notwendigkeit, Komponenten des Systems am Boden bzw. in der Türschwelle zu installieren.For the purposes of the present invention, all of the mentioned reflex radiation probes are suitable for forming preferred embodiments of the invention. Particularly preferred, however, are reflex light scanners in question, in particular infrared light radiation probe. Light sources of such reflex light sensors are in particular light emitting diodes and preferably IR laser diodes in question. Also, combined light sources, which can emit visible light and infrared light along the same optical path, for example, come into question, the visible light facilitates the adjustment of the sensor system or the monitoring device due to the visible light spot and the infrared light serves as the actual measuring light of the reflex light sensor. Suitable light sensors for detecting the reflected light are, for example, photodiodes, phototransistors or optionally photoresistors. Unlike conventional photoelectric retro-photoelectric sensors, which have a light emitter and light receiver on one side of the monitoring line and a light reflector on the opposite side of the monitoring line and responds to an interruption of the light beam on its way from the light emitter to the light reflector and the light reflector to the light receiver, the responds preferably used reflex light sensors on light, which is reflected by the object to be detected in the surveillance area itself. Photoelectric sensors, whether disposable photoelectric sensors or reflex photoelectric sensors, are less suitable for the invention, since they require a greater amount of assembly work and their reliable and reproducible function depends on whether the light receiver or light reflector is clean at its light entry window or has dirt , The fouling problem with light barriers is quite relevant for the considerations made here, since preferably the security zone to be monitored normally extends vertically from the upper end to the lower end of the relevant door and a light barrier element (transmitter, reflector or receiver) in the door threshold would be provided. However, this is a place prone to contamination, as it can easily be walked on with shoes by persons who pass through the door. This problem can easily be overcome with reflex radiation probes if the top door end is chosen as the installation location. Then there is no need to install components of the system on the floor or in the sill.

Im Rahmen der Erfindung könnten als Reflex-Strahlungstaster auch Systeme Verwendung finden, die mit Schallstrahlung, insbesondere Ultraschallstrahlung funktionieren und dementsprechend auf vom zu detektierenden Objekt im Überwachungsbereich zurück reflektierten Schall reagieren. Abgesehen von der speziellen Strahlungsart können solche Schallreflex-Taster entsprechend den Reflex-Lichttastern funktionieren.In the context of the invention, systems which use sound radiation, in particular ultrasound radiation, and which accordingly respond to sound reflected back from the object to be detected in the surveillance area, could also be used as reflex radiation sensors. Apart from the special kind of radiation, such sound reflex buttons can function according to the reflex light buttons.

Die Erfindung und ihre bevorzugten Ausführungsformen können bei Teleskopschiebetüren und bei nichtteleskopischen Schiebetüren Verwendung finden. Bei Teleskopschiebetüren kommt es bei dem Türöffnungsvorgang zur gemeinsamen seitlichen Bewegung wenigstens zweier Türblätter in einer gemeinsamen Türöffnungsrichtung, wobei die Türblätter parallel zueinander positioniert- und quer zur Türöffnungsbewegungsrichtung hintereinander angeordnet sind. Eines der Türblätter bewegt sich schneller als das andere Türblatt, so dass es beim Türöffnungsvorgang zu einem zunehmend größer werdenden Überlappungsbereich der beiden Türblätter kommt. In diesem Überlappungsbereich begrenzen die beiden Türblätter einen Spalt zwischen sich, der gelegentlich auch als Freilaufspalt bezeichnet wird. In ähnlicher Weise bildet sich auch dort ein Spalt, wo ein jeweiliges Türblatt bei der Türöffnungsbewegung mit einem Türrahmenabschnitt oder Türpfosten hintereinander liegend überlappt. Letztere Situation ist üblicherweise sowohl bei Teleskopschiebetüren als auch bei nicht teleskopischen Schiebetüren gegeben. Wie schon erwähnt, soll der Gefahr begegnet werden, dass Finger einer Person bei Berührung eines sich bewegenden Türblattes von diesem zu dem betreffenden Spalt mitgeführt und an dem Spalt bzw. in dem Spalt gequetscht werden. Ganz allgemein soll der Gefahr begegnet werden, dass kleine Gegenstände unbeabsichtigt in den Spalt gelangen und es dadurch zu Beschädigungen der Gegenstände oder/und der Schiebetür kommt.The invention and its preferred embodiments may find use in telescoping sliding doors and in non-telescopic sliding doors. In telescopic sliding doors occurs in the door opening operation for common lateral movement of at least two door leaves in a common door opening direction, the door leaves are positioned parallel to each other and arranged transversely to the door opening movement direction behind the other. One of the door leaves moves faster than the other door leaf, so that it comes in the door opening process to an increasingly larger overlap area of the two door leaves. In this overlap area, the two door leaves define a gap between them, which is sometimes referred to as a freewheeling gap. Similarly, there is also formed a gap where a respective door leaf in the door opening movement with a door frame section or door jamb overlapping lying behind each other. The latter situation is usually given both telescopic sliding doors and non-telescopic sliding doors. As already mentioned, the risk is to be met that fingers of a person carried on touching a moving door leaf from this to the relevant gap and squeezed at the gap or in the gap become. In general, the danger is to be met that small objects inadvertently get into the gap and this leads to damage to the items or / and the sliding door.

Hierzu wird gemäß der vorliegenden Erfindung eine Sicherungszone überwacht, die sich an einem quer zur Bewegungsrichtung des sich bewegenden Türblattes verlaufenden Rand des Überlappungsbereiches entlang dieses Randes erstreckt. Bei sich horizontal bewegenden Türblättern verläuft dieser Rand normalerweise vertikal. Dementsprechend verläuft auch die Sicherungszone normalerweise vertikal. Je nach Betriebsweise des Reflex-Strahlungstasters kann sich die Sicherungszone in bevorzugten Ausführungsformen über einen Bereich der vertikalen Länge des betreffenden Türblattes oder über die gesamte vertikale Türblattlänge erstrecken. Ein Reflex-Strahlungstaster sollte zweckmäßigerweise am oberen Ende des sich in Öffnungsbewegungsrichtung langsamer bewegenden Türblattes (bei der Teleskopschiebetür) oder/und oben nahe an dem Rahmenabschnitt angeordnet sein, hinter dem hinweg sich ein Türblatt bei der Türöffnungsbewegung bewegt. Der Reflex-Strahlungstaster ist bei einer solchen Einbaulage davor geschützt, von Benutzern der Schiebetür mit Schuhen betreten und dabei verschmutzt zu werden. Je nach Anordnung und Ausrichtung des Reflex-Strahlungstasters kann die Sicherungszone mehr oder weniger in den Spalt hinein oder außen nahe an dem Spalteingang eingerichtet werden. Gerät nun bei einem Türöffnungsvorgang ein Finger oder ein sonstiges Objekt in eine solche Sicherungszone, so reflektiert er Strahlung des Senders des Reflex-Strahlungstasters zum Strahlungsempfänger des Reflex-Strahlungstasters, bei Erfassung dieser reflektierten Strahlung signalisiert die Sicherungseinrichtung das Vorhandensein eines Objektes in der Sicherungszone, woraufhin die Antriebseinrichtung von der Steuereinrichtung dazu veranlasst wird, eine weitere Verschiebebewegung des sich bewegenden Türblattes zu unterbrechen.For this purpose, a security zone is monitored according to the present invention, which extends at a transverse to the direction of movement of the moving door leaf edge of the overlap region along this edge. For horizontally moving door leaves this edge usually runs vertically. Accordingly, the backup zone usually runs vertically. Depending on the mode of operation of the reflex radiation sensor, the security zone may in preferred embodiments extend over a region of the vertical length of the respective door leaf or over the entire vertical door leaf length. A reflex radiation probe should conveniently be located at the top of the door leaf moving slower in the direction of opening movement (in the telescoping sliding door) and / or close up to the frame portion behind which a door leaf moves during the door opening movement. The reflex radiation probe is protected in such an installation position from being entered by users of the sliding door with shoes and thereby polluted. Depending on the arrangement and orientation of the reflective radiation probe, the security zone can be set up more or less in the gap or outside close to the gap entrance. Device now in a door opening a finger or other object in such a backup zone, it reflects radiation from the transmitter of the reflex radiation sensor to the radiation receiver of the reflective radiation probe, upon detection of this reflected radiation, the security device signals the presence of an object in the security zone, whereupon the drive device is caused by the control device to interrupt a further displacement movement of the moving door leaf.

Da die Erfassung von Objekten bei entsprechender Einrichtung der Sicherungszone schon vor dem Spalteingang und insbesondere berührungslos erfolgen kann, ist eine sehr schnelle Reaktion der Sicherungseinrichtung bei Eindringen eines Objektes in die Sicherungszone möglich, wodurch verhindert werden kann, dass das Objekt überhaupt in den Spalt am Rande des Überlappungsbereiches gelangt. Es ist auch nicht erforderlich, dass das Objekt mit dem betreffenden Türblatt oder Rahmenabschnitt in Berührung kommt, bevor die Sicherungseinrichtung anspricht. Bereits bei Eindringen in den Strahlengang des Reflex-Strahlungstasters kann ein Objekt erfasst werden, bevor es überhaupt mit der Schiebetür in Berührung kommt. Auch dies dient der schnelleren Reaktion des Sicherungssystems. Die bevorzugten Ausführungsformen der erfindungsgemäßen Schiebetür zeichnen sich somit in besonderer Weise dadurch aus, dass ihr Sicherungssystem sehr schnell und zuverlässig reagiert, mit einfachen Mitteln realisierbar- und platzsparend mit geringem Aufwand installierbar ist.Since the detection of objects with appropriate means of the security zone can be done even before the column entrance and in particular contactless, a very fast response of the security device is possible when an object enters the security zone, which can be prevented that the object at all in the gap at the edge of the overlapping area. It is also not necessary that the object with the relevant door leaf or frame section comes into contact before the safety device responds. As soon as it penetrates the beam path of the reflex radiation probe, an object can be detected before it ever comes into contact with the sliding door. This also serves the faster response of the security system. The preferred embodiments of the sliding door according to the invention are thus characterized in a special way that their security system reacts very quickly and reliably, with simple means feasible and space-saving installable with little effort.

Die in den Figuren gezeigte automatische Schiebetür ist eine Teleskopschiebetür mit einem Rahmen 2 und zwei Türblättern 3, 5, die sich beim Öffnungsvorgang und Schließvorgang der Teleskopschiebetür in zwei hintereinander liegenden, parallelen Verschiebeebenen E3, E5 parallel zueinander ausgerichtet und horizontal zueinander bewegen. Die Türblätter 3,5 können z.B. aus Glasscheiben gebildet und durchsichtig sein. Eine Antriebseinrichtung 7 dient dazu, die Teleskopschiebetür auf entsprechende Anforderung zu öffnen oder zu schließen, wobei sich das in Fig. 1a rechts positionierte und gemäß Fig. 1a und 1b in der etwas weiter hinten liegenden Verschiebeebene E3 positionierte Türblatt 3 schneller bewegt als das in der etwas weiter vorne liegenden Verschiebeebene E5 positionierte Türblatt 5. Bei derartigen Teleskopschiebetüren wird das in Öffnungsbewegungsrichtung nachlaufende- und Schließbewegungsrichtung vorlaufende Türblatt (im Beispielsfall das Türblatt 3) üblicherweise mit ca. der doppelten Geschwindigkeit verschoben, wie das andere Türblatt.The automatic sliding door shown in the figures is a telescopic sliding door with a frame 2 and two door leaves 3, 5, which are parallel to each other during the opening operation and closing operation of the telescopic sliding door in two parallel sliding planes E3, E5 and move horizontally to each other. The door leaves 3.5 can be formed, for example, from glass sheets and be transparent. A drive device 7 serves to open or close the telescopic sliding door on request, wherein the in Fig. 1a positioned right and according to Fig. 1a and 1b In such a telescopic sliding doors in the direction of movement of the trailing and Schließbewegungsrichtung leading door leaf (in the example, the door leaf 3) is usually with approx the double speed, like the other door leaf.

Die beiden Türblätter 3,5 weisen orthogonal zu den Verschiebeebenen E3, E5 einen geringfügigen Abstand A voneinander auf, so dass sie ohne gegenseitige Berührung entlang der Verschiebeebenen E3, E5 in die Schließstellung gemäß Fig. 1a und in die Öffnungsstellung gemäß Fig. 2a verschoben werden können. Aufgrund der unterschiedlichen Bewegungsgeschwindigkeiten der Türblätter 3,5 kommt es bei einem Öffnungsvorgang der Teleskopschiebetür zu einem zunehmend größer werdenden Überlapp O (d.h. zu einer - in Richtung orthogonal zu den Verschiebeebenen E3, E5 gesehen - zunehmend größer werdenden gegenseitigen Überdeckung der beiden Türblätter 3,5) mit einem vertikalen Rand, der mit dem in Öffnungsbewegungsrichtung nachlaufenden vertikalen Rand 9 des langsamer laufenden Türblattes 5 zusammenfällt. Dabei begrenzen die beiden Türblätter 3,5 einen längs des Randes 9 verlaufenden schmalen vertikalen Spalt 11.The two door leaves 3.5 have orthogonal to the shift planes E3, E5 a slight distance A from each other, so that they without mutual contact along the shift planes E3, E5 in the closed position according to Fig. 1a and in the open position according to Fig. 2a can be moved. Due to the different speeds of movement of the door leaves 3,5 it comes in an opening operation of the telescopic sliding door to an increasingly larger overlap O (ie to a - Seen in the direction orthogonal to the shift planes E3, E5 - increasingly large mutual overlap of the two leaves 3.5) with a vertical edge coinciding with the trailing in the direction of movement of the vertical edge 9 of the slower-moving door leaf 5. In so doing, the two door leaves 3, 5 define a narrow vertical gap 11 extending along the edge 9.

Aufgrund der unterschiedlichen Bewegungsgeschwindigkeiten der beiden Türblätter 3,5 besteht bei derartigen Teleskopschiebetüren die Gefahr, dass das schneller bewegte Türblatt 3 daran anliegende Objekte beim Öffnungsvorgang seitlich in den Spalt 11 mitbewegt. Dies ist besonders kritisch, wenn Finger einer Person, insbesondere kleine Finger eines Kindes auf diese Weise an oder in den Spalt 11 gelangen und dabei Quetschungen erleiden. Es hat sich in der Vergangenheit des Öfteren gezeigt, dass kleine Kinder die Oberfläche von Glasscheiben gerne betasten und zwar auch Glasscheibentürblätter von Teleskoptüren. Dabei kann es leicht zu der vorstehend geschilderten Situation kommen.Due to the different speeds of movement of the two door leaves 3.5 in such telescopic sliding doors there is a risk that the faster moving door leaf 3 moves laterally adjacent thereto objects in the gap 11 during the opening process. This is particularly critical when a person's fingers, in particular a child's little fingers, reach or enter the gap 11 in this way and suffer from bruising. It has often been shown in the past that small children like to feel the surface of glass panes, including glass pane door leaves of telescopic doors. This can easily lead to the situation described above.

Die vorliegende Erfindung setzt an dieser Problematik an und bietet eine besonders vorteilhafte Möglichkeit, das Eindringen von Objekten in den Spalt zwischen den Türblätter 3,5 zu verhindern.The present invention addresses this problem and offers a particularly advantageous possibility to prevent the penetration of objects into the gap between the door leaves 3,5.

Hierzu bietet die Verwendung von Reflex-Strahlungstastern eine zuverlässige und einfache Möglichkeit der Überwachung einer Sicherungszone 13, die sich nahe an dem Spalteingang längs des Randes 9 des Überlapps O der beiden Türblätter 3,5 erstreckt, und der sofortigen Unterbindung oder Unterbrechung der Türöffnungsbewegung der beiden Türblätter, wenn sich ein Objekt in der Sicherungszone 13 befindet bzw. darin eindringt.For this purpose, the use of reflex radiation scanners provides a reliable and easy way of monitoring a security zone 13, which extends close to the gap entrance along the edge 9 of the overlap O of the two leaves 3.5, and the immediate suppression or interruption of the door opening movement of the two Door leaves when an object is in the security zone 13 or penetrates therein.

Hierzu ist eine Sicherungseinrichtung vorgesehen, welche einen Reflex-Lichttaster 15 aufweist, der im Beispielsfall am oberen Ende des langsamer laufenden Türblattes 5 befestigt und so orientiert ist, dass er mit seinem Strahlungssender 19 einen Lichtstrahl 17 vertikal nach unten aussendet. Dieser Lichtstrahl 17 definiert die zu überwachende Sicherungszone 13. Der Reflex-Lichttaster 15 weist auch einen Strahlungsempfänger 21 oder Strahlungssensor auf. Der Reflex-Lichttaster 15 funktioniert so, dass er auf Licht seines Strahlungssenders 19 reagiert, welches von einem Objekt in der Sicherungszone 13 zu den Strahlungsempfänger 21 reflektiert wird, nicht aber auf das Licht seines Strahlungssenders 19, welches die Sicherungszone 13 ungehindert von oben nach unten passiert.For this purpose, a safety device is provided, which has a reflex light sensor 15, which is fastened in the example at the upper end of the slower-moving door leaf 5 and oriented so that it with his Radiation transmitter 19 emits a light beam 17 vertically downwards. This light beam 17 defines the security zone 13 to be monitored. The reflex light sensor 15 also has a radiation receiver 21 or radiation sensor. The reflex light sensor 15 functions to respond to light from its radiation transmitter 19, which is reflected by an object in the security zone 13 to the radiation receiver 21, but not to the light of its radiation transmitter 19, which the security zone 13 unhindered from top to bottom happens.

In Fig. 3a und 3b ist eine Situation angedeutet, in der eine Person 23 mit einer Hand 25 in die Sicherungszone 13 eingreift. Dabei unterbricht die Person 23 den unten gerichteten Lichtstrahl 17 mit der Hand 24 und es kommt zur (normalerweise diffusen) Rückreflexion von Licht dieses Lichtstrahls 17 zu dem Reflex-Lichttaster 15 durch die Hand 24. Der Lichtempfänger 21 des Reflex-Lichttaster 15 registriert derart rückreflektiertes Licht, was als Vorhandensein eines Objektes in der Sicherungszone 13 interpretiert wird. Der Reflex-Lichttaster 15 steht mit einer Steuereinrichtung 25 der Teleskopschiebetür in Datenübertragungsverbindung. Die Steuereinrichtung 25 erhält von dem Reflex-Lichttaster 15 ein Störmeldesignal, wenn das Vorhandensein eines Objektes in der Sicherungszone 13 in der vorstehend erläuterten Weise erfasst wird.In Fig. 3a and 3b is a situation indicated in which a person 23 engages with a hand 25 in the security zone 13. In this case, the person interrupts the 23 downwardly directed light beam 17 with the hand 24 and there is the (normally diffuse) back reflection of light of this light beam 17 to the reflex light sensor 15 by the hand 24. The light receiver 21 of the reflex light sensor 15 registers such retro-reflected Light, which is interpreted as the presence of an object in the security zone 13. The reflex light sensor 15 is connected to a control device 25 of the telescopic sliding door in data transmission connection. The control device 25 receives from the reflex light sensor 15 an error message signal when the presence of an object in the security zone 13 is detected in the manner explained above.

Die Steuereinrichtung 25 dient auch zur Steuerung der Türantriebseinrichtung 7, d.h. sie erzeugt Steuer- und Schaltbefehle für einen Elektromotor 27, um ihn gesteuert mit elektrischer Antriebsenergie zu versorgen und die jeweilige Motordrehrichtung vorzugeben. Je nach Motordrehrichtung des Elektromotors 27 bewegen sich die Türblätter 3, 5 in Öffnungsbewegungsrichtung oder in Schließbewegungsrichtung. Bei der in den Figuren stark vereinfacht dargestellten Türantriebseinrichtung 7 handelt es sich um einen Seilzugantrieb, bei dem der Elektromotor 27 über einen Transmissionsriemen 29 oder dgl. eine Umlenkrolle 31 rechts oberhalb der Türöffnung 4 antreibt, wobei die Umlenkung 31 zwei konzentrisch zur Umlenkrollenachse aneinander angeordnete zylindrische Umlenkrollenabschnitte 33,35 aufweist, von denen der Umlenkrollenabschnitt 33 einen größeren Durchmesser hat als der Umlenkrollenabschnitt 35. Jeder der beiden Umlenkrollenabschnitte 33,35 ist von einem jeweiligen Endloszugseil 37,39 umschlungen und dient zu dessen Antrieb und Umlenkung. Eine zweite Umlenkrolle 41 ist links oberhalb der Türöffnung 4 drehbar angeordnet und weist ebenfalls zwei konzentrisch zu ihrer Umlenkrollenachse aneinander angeordnete zylindrische Umlenkrollenabschnitte 43,45 mit entsprechend unterschiedlichen Durchmessern auf, welche von den Endloszugseilen 37,39 umschlungen werden und zu deren Umlenkung dienen. Mit dem unteren Trum 36 des um die Umlenkrollenabschnitte 33,43 mit größerem Durchmesser umlaufenden Endloszugseils 37 ist das schneller laufende Türblatt 3 über ein Mitnehmerelement 47 verbunden, wohingegen mit dem unteren Trum 38 des um die Umlenkrollenabschnitte 35,45 umlaufenden Endloszugseils 39 das andere Türblatt 5 über ein Mitnehmerelement 49 verbunden ist. Wird der Elektromotor 27 so angesteuert, dass er die Umlenkrolle 31 zur Drehung in Uhrzeigersinn (bezogen auf Fig. 1a) antreibt, so bewegen sich die Mitnehmerelemente 47,49 mit den unteren Trumen 36,38 in Fig. 1a nach links, so dass die Türblätter 3,5 ebenfalls im Türöffnungsbewegungsrichtung nach links verschoben werden. Wird der Elektromotor 27 so angesteuert, dass er die Umlenkrolle 31 zur Drehung entgegengesetzt dem Uhrzeigersinn (bezogen auf Fig. 2a) antreibt, so werden die Türblätter 3,5 aus ihrer Öffnungsstellung gemäß Fig. 2a in Schließbewegungsrichtung nach rechts mit dem unteren Trumen 36,38 bewegt.The control device 25 also serves to control the door drive device 7, ie it generates control and switching commands for an electric motor 27 in order to supply it under control with electrical drive energy and to specify the respective direction of motor rotation. Depending on the direction of motor rotation of the electric motor 27, the door leaves 3, 5 move in the direction of opening movement or in the closing movement direction. The door drive device 7 shown greatly simplified in the figures is a cable drive in which the electric motor 27 via a transmission belt 29 or the like. A deflection roller 31 drives right above the door opening 4, wherein the deflection 31 two concentrically arranged to Umlenkrollenachse each other cylindrical Umlenkrollenabschnitte 33,35, of which the Umlenkrollenabschnitt 33 has a larger diameter than the Umlenkrollenabschnitt 35. Each of the two Umlenkrollenabschnitte 33,35 is looped by a respective Endloszugseil 37,39 and serves to drive and deflection. A second deflection roller 41 is rotatably mounted on the left above the door opening 4 and also has two concentric with their Umlenkrollenachse arranged cylindrical Umlenkrollenabschnitte 43,45 with correspondingly different diameters, which are looped by the Endloszugseilen 37,39 and serve to their deflection. With the lower run 36 of the Umlenkrollenabschnitte 33,43 with larger diameter rotating Endloszugseils 37, the faster-running door leaf 3 is connected via a driver 47, whereas with the lower run 38 of the Umlenkrollenabschnitte 35,45 circulating Endloszugseils 39 the other door 5 is connected via a driver element 49. If the electric motor 27 is controlled so that it the deflection roller 31 for rotation in a clockwise direction (based on Fig. 1a ) drives, so the driver elements 47,49 move with the lower runs 36,38 in Fig. 1a to the left, so that the door leaves 3.5 are also moved in the Türöffnungsbewegungsrichtung to the left. If the electric motor 27 is controlled so that it the deflection roller 31 for rotation in the counterclockwise direction (relative to Fig. 2a ) drives, the door leaves are 3.5 from its open position according to Fig. 2a moved in the closing movement direction to the right with the lower Trumen 36,38.

Da das Zugseil 37 um die Umlenkrollenabschnitte 33,43 mit den größeren Durchmessern umläuft, hat es eine größere Umlaufgeschwindigkeit als das andere Zugseil 39, welches um die Umlenkrollenabschnitte 35,45 mit den kleineren Durchmessern umläuft. Dementsprechend wird das von dem Zugseil 37 mitbewegte Türblatt 3 auch schneller in Türschließbewegungsrichtung und den Türöffnungsbewegungsrichtung verschoben als das von dem Zugseil 39 mitbewegte Türblatt 5. Je nachdem, ob die Steuereinrichtung 25 den Elektromotor 27 zur Drehung im Uhrzeigersinn oder entgegen dem Uhrzeigersinn ansteuert, werden die Türblätter 3,5 in Türschließbewegungsrichtung oder in Türöffnungsbewegungsrichtung verschoben.Since the traction cable 37 revolves around the Umlenkrollenabschnitte 33,43 with the larger diameters, it has a greater rotational speed than the other Zugseil 39, which rotates about the Umlenkrollenabschnitte 35,45 with the smaller diameters. Accordingly, the moving of the pull cable 37 door leaf 3 is also moved faster in Türschließbewegungsrichtung and the door opening movement direction than that of the pull cable 39 mitbewegte door leaf 5. Depending on whether the controller 25, the electric motor 27 for rotation in a clockwise or counterclockwise direction the door leaves 3, 5 are moved in the door closing movement direction or in the door opening movement direction.

Es sei an dieser Stelle deutlich betont, dass die vorstehend erläuterte Zugseilantriebseinrichtung 7 lediglich exemplarisch als eine geeignete Antriebseinrichtung für eine erfindungsgemäße Schiebetür vorgestellt wurde. Es kommen auch andere Antriebseinrichtungen, etwa Spindelantriebe, Linearmotorantriebe usw. als Türantriebe in Frage.It should be emphasized at this point that the above-described Zugseilantriebseinrichtung 7 has been presented by way of example only as a suitable drive means for a sliding door according to the invention. There are also other drive devices, such as spindle drives, linear motor drives, etc. as door drives in question.

Wesentlich für die Erfindung ist lediglich, dass der betreffende Antriebsmotor der Antriebseinrichtung aus den nachstehend erläuterten Gründen schnell auf Richtungsumkehr-Steueranweisungen der betreffenden Steuereinrichtung reagiert.It is only essential for the invention that the relevant drive motor of the drive device reacts quickly to direction reversal control instructions of the relevant control device for the reasons explained below.

Tritt der in Fig. 3a und 3b illustrierte Fall ein, dass die Sicherungseinrichtung das Vorhandensein eines Objektes 25 in der Sicherungszone 13 detektiert, so reagiert die Steuereinrichtung 25 darauf unverzüglich mit der Abgabe einer Richtungsumkehr-Steueranweisung an den Elektromotor 27, so dass dem Elektromotor 27 nicht nur die elektrische Antriebsenergie zur aktuellen Verschiebung der Türblätter 3,5 in Türöffnungsbewegungsrichtung genommen wird, sondern der Elektromotor 27 darüber hinaus einen kurzen Impuls elektrischer Antriebsenergie zur Bewegungsrichtungsumkehr ("Schubumkehrimpuls") erhält. Auf diese Weise wird einer weiteren Trägheitsbewegung der Türblätter 3,5 in Türöffnungsbewegungsrichtung nach Unterdrückung der betreffenden elektrischen Antriebsenergie auf ein Störmeldesignal des Reflex-Lichttasters 15 aktiv entgegengewirkt. Damit wird erreicht, dass nach Erfassung eines Objektes 25 in der Sicherungszone 13 eine weitere Bewegung der Türblätter 3, 5 in Türöffnungsbewegungsrichtung schnellstmöglich gestoppt wird. Die Dauer eines solchen "Schubumkehrimpulses" kann ggf. abhängig von der Masse bzw. Massenträgheit der Türblätter 3,5 gewählt werden.Kick the in Fig. 3a and 3b illustrated case that the safety device detects the presence of an object 25 in the safety zone 13, the controller 25 responds promptly with the delivery of a direction reversal control instruction to the electric motor 27, so that the electric motor 27 not only the electric drive energy to the current displacement the door leaves 3, 5 are taken in the door opening movement direction, but the electric motor 27 also receives a short pulse of driving electric power for reversing the direction of travel ("thrust reversing pulse"). In this way, a further inertial movement of the door leaves 3.5 is actively counteracted in the door opening movement direction after suppression of the relevant electrical drive energy to a fault message signal of the reflex light sensor 15. This ensures that after detection of an object 25 in the security zone 13, a further movement of the door leaves 3, 5 in the door opening movement direction is stopped as quickly as possible. The duration of such a "thrust reverser pulse" may optionally be selected depending on the mass or mass inertia of the door leaves 3.5.

Nachzutragen ist noch, dass eine zweite Sicherungszone 13' am Rahmen 2 links oben an der Türöffnung 4 eingerichtet sein, wobei ein entsprechender Reflex-Strahlungstaste 15' diese zweite Sicherungszone 13' definiert und überwacht, um die Annäherung eines Objektes an den Überlappspalt 6 zwischen dem die Türöffnung 4 links begrenzenden Rahmenabschnitt 8 und dem zweiten Türblatt 5 zu detektieren und im Fall der Erfassung eines Objektes in der zweiten Sicherungszone 13' die Steuereinrichtung zur Auslösung eines Notstopps hier zumindest des zweiten Türblattes 5 in der Weise zu veranlassen, wie dies im Bezug auf die Erfassung eines Objektes in der Sicherungszone 13 beschrieben worden ist.It should also be added that a second security zone 13 'on the frame 2 at the top left of the door opening 4 be set, with a corresponding reflection radiation key 15' defines this second security zone 13 'and monitors the approach of an object to the overlap gap 6 between the to detect the door opening 4 left bordering frame portion 8 and the second door leaf 5 and in the case of detection of an object in the second security zone 13 'to cause the control device to trigger an emergency stop here at least the second door leaf 5 in the manner described in relation to the detection of an object in the security zone 13 has been described.
