Definitions
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- the monitoring device signals an intrusion or the presence of an object in the security zone by a corresponding fault signal.
- 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.
- 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.
- 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.
- 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.
- 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.
- the monitoring devices of the safety devices should also have a compact design and not susceptible to damage.
- 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.
- 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.
- the emergency stop process ie the process of interrupting the sliding movement of a respective door leaf when an object enters the security zone.
- a sliding door in particular an automatic elevator sliding door, 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.
- 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.
- 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.
- 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.
- a pulse of electrical energy (“thrust reverser pulse”)
- the maximum available in the drive system electric drive energy can be provided during the thrust reverser pulse for the engine.
- 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.
- 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.
- 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.
- At least the first door element comprises or is formed from a glass pane.
- the sliding door can be, for example, an elevator door, in particular a telescopic sliding door of an elevator car or an elevator shaft.
- 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.
- reflex radiation probes are suitable for forming preferred embodiments of the invention.
- 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.
- 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.
- 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.
- sound reflex buttons can function according to the reflex light buttons.
- the invention and its preferred embodiments may find use in telescoping sliding doors and in non-telescopic sliding doors.
- 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.
- the two door leaves define a gap between them, which is sometimes referred to as a freewheeling gap.
- 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.
- 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 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.
- 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 Schfederschiscardi leading door leaf (in the example, the door leaf 3) is usually with approx the double speed, like the other door leaf.
- 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.
- 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.
- 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.
- a safety device 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.
- Fig. 3a and 3b is a situation indicated in which a person 23 engages with a hand 25 in the security zone 13.
- 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.
- 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.
- 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 Umlenkrollenabête 33,35, of which the Umlenkrollenabexcellent 33 has a larger diameter than the Umlenkrollenabrough 35.
- Each of the two Umlenkrollenabitese 33,35 is looped by a respective Endloszugseil 37,39 and serves to drive and deflection.

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.

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
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
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
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
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
In
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
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
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
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.
