Abstract

The door has at least one sliding door panel (1) coupled to an operating drive (3) via an intermediate displacement rod (5). This is formed in two parts, with one element coupled to the displacement drive. Another setting element is operated by an auxiliary drive to allow movement of the sliding door panel into the open position, independent of the main operating drive. The auxiliary drive acts directly or indirectly between the first element of the displacement rod and the setting element which is movable relative to it e.g. via a telescopic mechanism.

Description

Die Erfindung betrifft eine automatische Schiebetür mit mindestens einem Flügel nach dem Oberbegriff des Anspruches 1.The invention relates to an automatic sliding door at least one wing according to the preamble of the claim 1.

Eine gattungsbildende automatische Schiebetür ist aus der DE 44 00 940 C1 bekannt geworden. Die gattungsbildende Schiebetür zeichnet sich dadurch aus, daß die einen Türflügel tragende Laufeinrichtung über eine Kupplung mit einem Mitnehmer gekoppelt und davon trennbar ist, der durch einen üblicherweise verwendeten umlaufenden Riemen angetrieben wird. Über diesen Mitnehmer und die im Normal-Betrieb geschlossene Kupplung wird die Laufwageneinrichtung und damit die Türflügel in ihre jeweilige Öffnungs- und Schließstellung bewegt.A generic automatic sliding door is out of the DE 44 00 940 C1 become known. The generic Sliding door is characterized in that the one door leaf load-bearing running device with a clutch is coupled to a driver and is separable from it through a commonly used circumferential belt is driven. About this driver and in normal operation closed coupling becomes the carriage device and thus the door leaves in their respective opening and closed position moves.

Bei Stromausfall wird die zwischen der Mitnahme- und der Laufwageneinrichtung vorgesehene Kupplung automatisch geöffnet, so daß ein mit der gesamten Anordnung mit bewegbarer Hilfsantrieb wirksam wird und die Tür, bei nunmehr durch den Stromausfall nicht fortbewegtem Mitnehmer bzw. nicht fortbewegtem Antriebs- oder Übertragungsmittel, in die Öffnungsstellung verstellt wird.In the event of a power failure, the between the take-away and the Carriage device provided coupling automatically opened so that one with the entire arrangement with movable Auxiliary drive takes effect and the door, at now driver not moved due to power failure or immobile propulsion or transmission means, in the opening position is adjusted.

Dieses Konstruktionsprinzip zeichnet sich dadurch aus, daß der als Hilfsantrieb dienende Kraftspeicher als mitlaufender Kraftspeicher ausgebildet ist. D.h., in Abweichung zu noch früher bekannt gewordenen Lösungen ist der Kraftspeicher stets geladen. D.h., er muß bei jeder neuen Schließbewegung der Tür nicht jedesmal neu geladen werden, da während des ungestörten Betriebes beim Öffnen des Türflügels auch keine zwingend vorgeschriebene Entladung des Kraftspeichers erforderlich ist.This design principle is characterized in that the energy accumulator serving as an auxiliary drive as a rotating one Lift mechanism is designed. That is, in deviation from Solutions that became known even earlier are the energy accumulator always loaded. In other words, it has to be added to every new one Do not reload the door closing movement each time since during undisturbed operation when opening the Door wing also no mandatory discharge the lift mechanism is required.

Bei einem in der gattungsbildenden Vorveröffentlichung beschriebenen Ausführungsbeispiel ist eine Schiebetür über zwei in deren Längsrichtung versetzt angeordnete Laufwagen an einer Schienenanordnung aufgehängt und längs dieser verfahrbar. Als Mitnahmeeinrichtung und damit als Antriebs- und Verbindungsglied ist ein weiterer Laufwagen vorgesehen.With one in the generic prepublishing The embodiment described is a sliding door two carriages offset in the longitudinal direction hung on a rail arrangement and along it movable. As a driving device and thus as a drive and link is another carriage intended.

Obgleich sich dieses Konstruktionsprinzip durchaus bewährt hat, ist es Aufgabe der vorliegenden Erfindung, ausgehend von diesem gattungsbildenden Stand der Technik, eine nochmals verbesserte automatische Schiebetür mit mindestens einem Flügel zu schaffen.Although this construction principle has proven itself has, it is an object of the present invention, starting from this generic state of the art, one more improved automatic sliding door with at least to create a wing.

Die Aufgabe wird erfindungsgemäß entsprechend den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The task is according to the invention in accordance with the claim 1 specified features solved. Advantageous configurations of the invention are in the subclaims specified.

Die erfindungsgemäße Schiebetür weist gegenüber dem vorbekannten Stand der Technik weitere wesentliche Vorteile auf. The sliding door according to the invention has compared to the previously known State of the art further significant advantages on.

Erfindungsgemäß ist nämlich nunmehr vorgesehen, daß eine Schubstange verwendet wird. Schubstangen sind zwar an sich im Stand der Technik bekannt. Erfindungsgemäß ist aber nunmehr vorgesehen, daß die Schubstangenanordnung zumindest zweigeteilt, vorzugsweise teleskopartig ausgebildet ist, und dabei zwischen den beiden zusammenwirkenden Teilen der Schubstangenanordnung der Kraftspeicher sitzt und bei Bedarf wirksam ist.According to the invention it is now provided that a Push rod is used. Push rods are in themselves known in the art. According to the invention now provided that the push rod assembly at least divided into two, preferably telescopic and between the two interacting parts the push rod assembly of the energy storage sits and is effective when needed.

Dadurch läßt sich erfindungsgemäß eine derart konzipierte Schubstange bei unterschiedlich groß dimensionierten Flügeltüren einsetzen. Bei einer durchschnittlichen Länge einer derartigen erfindungsgemäßen Schubstange lassen sich problemlos Flügeltüren mit einer Öffnungsweite von 800 mm bis 2300 mm realisieren.According to the invention, this can be designed in this way Push rod for wing doors of different sizes deploy. With an average length such a push rod according to the invention can Gullwing doors with an opening width of 800 mm are no problem up to 2300 mm.

In einer bevorzugten Ausführungsform wird für die erfindungsgemäßen Schubstangenanordnungen ein ebenfalls an sich bekannter Kraftspeicher in Form eines elastomeren Elementes, insbesondere eines gummielastischen Seiles, verwendet. Aber auch ein Kraftspeicher in Form einer Druckfeder, insbesondere Gasdruckfeder, ist letztendlich möglich.In a preferred embodiment for the invention Push rod assemblies also in themselves known energy store in the form of an elastomeric element, especially a rubber-elastic rope used. But also an energy store in the form of a compression spring, in particular gas pressure spring, is ultimately possible.

Die erfindungsgemäße Anordnung ermöglicht es gemäß einem Ausführungsbeispiel, daß das gummielastische Kraftspeicher-Element in Seilform über die wesentliche Länge der erfindungsgemäßen Schubstange, d.h. des Schubstangen-Grundelementes, verlegt und am vorderen Ende des mit dem Riemenantrieb mit verfahrbaren Schubstangen-Grundelementes unter Umlenkung um 180° zurückgeführt wird. Eine Vergrößerung der elastischen Kraftwirkung des so gebildeten Hilfsantriebes läßt sich dadurch erzielen, daß das gummielastische Seilelement doppelt verlegt wird. Dabei kann es einstückig ausgebildet sein, so daß das gummielastische Element in der Mitte am Ende des bevorzugt teleskopartig ausfahrbaren Schubstangenelementes an diesem angreift und insbesondere bei Abnormbetrieb die damit gekoppelte Flügeltür öffnet.The arrangement according to the invention makes it possible according to one Embodiment that the rubber-elastic energy storage element in rope form over the essential length of the push rod according to the invention, i.e. the push rod basic element, misplaced and at the front end of the with the Belt drive with movable push rod basic element is returned by deflection by 180 °. An enlargement the elastic force effect of the auxiliary drive thus formed can be achieved in that the rubber elastic Rope element is laid twice. It can be in one piece be designed so that the rubber-elastic element in the middle at the end of the preferably telescopic extendable push rod element attacks this and the wing door coupled with it, particularly in the case of abnormal operation opens.

In einer bevorzugten Ausführungsform ist aber auch vorgesehen, daß das Gummiseil mit einer separaten Seilüberwachungseinrichtung stets auf seine Funktionstüchtigkeit überwacht wird. Würde aus irgendeinem Grunde das gummielastische Seil reißen oder aber durch langzeitigen Einsatz die gummielastischen Kräfte unter ein Mindestmaß absinken, kann mit der Gummiseil-Überwachung ebenfalls ein automatisches Umschalten in Abnormbetrieb erfolgen, verbunden mit einem automatischen Öffnen der zugehörigen Flügeltür.In a preferred embodiment but it is also provided that the rubber rope always with a separate rope monitoring device is monitored for its functionality. Would out for some reason tear the rubber elastic rope or but through long-term use the rubber-elastic forces can fall below a minimum with the rubber rope monitoring also an automatic switch to Abnormal operation take place, combined with an automatic Open the corresponding wing door.

Auch bei üblichen Testfahrten, bei denen in der Regel einmal am Tag zumindest ein Abnormbetrieb simuliert wird, kann mit dem erfindungsgemäßen Antrieb bei Wiederzuschaltung des üblichen Antriebsaggregates der üblicherweise verwendete Riemenantrieb so verfahren werden, daß das daran gekoppelte erste Schubstangenelement (Schubstangen-Grundelement) entgegen der Kraft des Hilfsantriebs-Speichers auf das relativ dazu verfahrbare zweite Schubstangenelement (Schubstangen-Stellelement) auffährt und dieses wieder in seiner Normalbetriebsstellung einfängt und verriegelt.Even with normal test drives, where usually at least one abnormal operation is simulated once a day, can with the drive according to the invention when reconnected the usual drive unit of the usual used belt drive so that the coupled first push rod element (push rod basic element) against the force of the auxiliary drive accumulator to the second push rod element which can be moved relative to it (Push rod actuator) opens and this catches again in its normal operating position and locked.

In einer bevorzugten Ausführungsform ist auch vorgesehen, daß die eigentliche Verriegelung des Hilfsantriebes mechanisch erfolgt, wohingegen die Auslösung magnetisch bewerkstelligt wird. Dadurch müssen mittels des Magneten nur vergleichsweise geringe Kräfte aufgebracht werden, um die Sicherungseinrichtung in üblicher Betriebsstellung zu halten. Bei Abnormbetrieb und Stromausfall oder bei einem Nachlassen der Zugkräfte des gummielastischen Seiles würde durch die erfindungsgemäß bevorzugt vorgesehene Gummiseil-Überwachung ein den Magneten mit Strom versorgender Stromkreis durch Betätigung eines Schalters unterbrochen und dadurch der entsprechende Magnet abgeschaltet werden. Auch hierdurch wird sofort die zugeordnete Schiebetür wieder in Öffnungsstellung verfahren.In a preferred embodiment it is also provided that the actual locking of the auxiliary drive mechanically takes place, whereas the triggering is magnetically effected becomes. This means that the magnet only has to be used comparatively low forces are applied to the belay device to keep in normal operating position. In the event of abnormal operation and power failure or one The tensile forces of the rubber-elastic rope would decrease by the rubber rope monitoring preferably provided according to the invention a circuit supplying power to the magnet interrupted by operating a switch and the corresponding magnet can be switched off. Also this will immediately switch the assigned sliding door back in Move to the open position.

In den Figuren 1 und 2 ist in schematischer auszugsweiser Darstellung eine Schiebetür mit zwei Schiebetürflügeln 1 gezeigt, und zwar in Figur 1 in geschlossener und in Figur 2 in geöffneter Stellung.In Figures 1 and 2 is a schematic excerpt Representation of a sliding door with two sliding door leaves 1 shown, in Figure 1 in closed and in Figure 2 in the open position.

Über einen umlaufenden Riemenantrieb 3 werden die Türen zwischen ihrer Verschluß- und ihrer Öffnungsstellung verfahren, wobei die Schiebetürflügel 1 üblicherweise mittels zweier in Längsrichtung der Türen versetzt angeordneten Laufwagen an einer im Bereich des Riemenantriebes 3 längs verlaufenden Schiene abgestützt sind.The doors are driven by a belt drive 3 move between their closed and open positions, the sliding door leaf 1 usually by means of two offset in the longitudinal direction of the doors Carriage on a longitudinally in the area of the belt drive 3 extending rail are supported.

Wie aus der Darstellung gemäß Figur 1 und 2 hervorgeht, ist jeder Schiebetürflügel 1 mit einer ihm zugeordneten Schubstange 5 mit integriertem Hilfsantrieb verbunden. Mit anderen Worten ist hier die Schubstange 5 an ihrem einen Ende an dem entsprechenden oberen oder unteren Trumen des Riemenantriebes 3 befestigt, wobei das gegenüberliegende Ende der Schubstange 5 mit dem betreffenden Schiebetürflügel 1 verbunden ist.As can be seen from the illustration according to FIGS. 1 and 2, is each sliding door leaf 1 with one assigned to it Push rod 5 connected to an integrated auxiliary drive. With in other words, the push rod 5 is on one of them End at the corresponding upper or lower strand of the Belt drive 3 attached, the opposite End of the push rod 5 with the relevant sliding door leaf 1 is connected.

Durch die versetzte Abstützung dieser Schubstange 5 mit ihrem einen Ende am Riemenantrieb 3 und dazu versetzt mit ihrem anderen Ende am zugeordneten Schiebetürflügel 1 ergibt sich die Möglichkeit, daß bei gleichbleibender Dimensionierung und gleichem Abstand der beiden in den Figuren 1 und 2 gezeigten Umlenkrollen 7 für den Riemenantrieb 3 durch versetzte Wahl der Abstützstellen der Schubstangen 5 am Riemenantrieb 3 und/oder an dem jeweiligen Schiebetürflügel 1 unterschiedliche Öffnungsweiten für die Tür von beispielsweise 800 mm bis 2300 mm realisiert werden können, da die Schiebetürflügel 1 sogar über die außenliegenden Umlenkrollen 7 hinaus durch Verwendung der Schubstange 5 in Öffnungsstellung verschoben werden können. Due to the offset support of this push rod 5 with one end of the belt drive 3 and offset with their other end on the associated sliding door leaf 1 results the possibility that with the same dimensioning and the same distance between the two in the figures 1 and 2 shown pulleys 7 for the belt drive 3rd through offset selection of the support points of the push rods 5 on the belt drive 3 and / or on the respective sliding door leaf 1 different opening widths for the door from 800 mm to 2300 mm, for example can, because the sliding door 1 even over the outside Deflection rollers 7 also by using the Push rod 5 can be moved into the open position.

Anhand der folgenden Figuren wird nunmehr der weitere Aufbau der erwähnten Schubstange 5 erläutert.With the help of the following figures, the further one is now Structure of the mentioned push rod 5 explained.

Die Schubstange 5 besteht dabei im gezeigten Ausführungsbeispiel aus einem Schubstangen-Grundelement 5a und einem relativ dazu mittels des integrierten Hilfs-Kraftantriebes verfahrbaren Schubstangen-Stellelement 5b, welches im gezeigten Ausführungsbeispiel teleskopartig mittels eines Hilfsantriebes zur axialen Verlängerung der Schubstange 5 ausgefahren werden kann.The push rod 5 is in the embodiment shown from a push rod base element 5a and one relative to this by means of the integrated auxiliary power drive movable push rod actuator 5b, which in Exemplary embodiment shown telescopically by means of a Auxiliary drive for the axial extension of the push rod 5 can be extended.

Anhand der Figuren 3 und 4 ist dabei das Wirkprinzip erläutert.The principle of action is explained with reference to FIGS. 3 and 4.

An dem Schubstangen-Grundelement 5a ist ein gummielastischer Seilzug an Seilbefestigungspunkten 9 befestigt und von diesen Befestigungsstellen (in der Nähe des Endes des Schubstangen-Grundelementes 5a) über am anderen Ende des Schubstangen-Grundelementes 5a sitzende Umlenkrollen 11 umgelenkt und unter Bildung einer Schlaufe 13 in dem hohlen Querschnitt des Schubstangen-Grundelementes 5a verlegt (auf die weiteren konstruktiven Einzelheiten der Schubstange wird später noch anhand der Figuren 5ff eingegangen). Dabei ist der gummielastische Seilzug 15 von der Schlaufenumkehrung 13 wieder parallel zurückverlegt, und zwar um eine zur ersten Umlenkrolle 11 parallele Umlenkrolle 11 zu dem zweiten Seilbefestigungspunkt 9.On the push rod base element 5a is a rubber elastic Cable attached to cable attachment points 9 and from these attachment points (near the end of the Push rod base element 5a) over at the other end of the Push rod base element 5a seated deflection rollers 11 deflected and forming a loop 13 in the hollow Cross section of the push rod base element 5a (on the further design details of the push rod will be discussed later with reference to Figures 5ff). The rubber-elastic cable 15 is of the Loop reversal 13 moved back in parallel again, and namely a deflection roller parallel to the first deflection roller 11 11 to the second rope attachment point 9.

Das relativ verfahrbare Schubstangen-Stellelement 5b ist im üblichen Betrieb mehr oder weniger ganz in das Schubstangen-Grundelement 5a eingeschoben, wobei die Schlaufe 13 das rückwärtige Ende des eingeschobenen Schubstangen-Stellelementes 5b druckbeaufschlagt. In dieser Grundposition ist das System gespannt, wie es in Figur 3 dargestellt ist. The relatively movable push rod actuator 5b in normal operation more or less entirely in the push rod basic element 5a inserted, the loop 13 the rear end of the inserted push rod actuator 5b pressurized. In this basic position the system is excited, as shown in Figure 3 is.

Im Abnormbetrieb wird ein entsprechender Sperrmechanismus freigegeben, so daß durch die Zugkraft des gummielastischen Seilzuges 15 über die am rückwärtigen Ende des Schubstangen-Stellelementes 5b angreifende Schlaufe das Schubstangen-Stellelement im Sinne einer Axialverlängerung der gesamten Schubstange 5 relativ zu dem am Riemenantrieb 3 abgestützten Schubstangen-Grundelement 5a ausfährt. Dadurch kann auch bei der Grundstellung der in Figur 1 dargestellten geschlossenen Schiebetür allein durch Wirksamwerden des so gebildeten Hilfsantriebes im Abnormfalle durch die erwähnte axiale Verlängerung der Schubstange 5 insgesamt, selbst bei stehendem Riemenantrieb 3, der jeweilige Schiebetürflügel in seine in Figur 2 gezeigte Öffnungsstellung verschoben werden.A corresponding locking mechanism is used in abnormal operation released so that by the tensile force of the rubber elastic Cable 15 over the at the rear end of Push rod actuator 5b attacking the loop Push rod actuator in the sense of an axial extension the entire push rod 5 relative to that on the belt drive 3 supported push rod base element 5a extends. Thereby can also in the basic position shown in Figure 1 closed sliding door only by taking effect of the auxiliary drive thus formed in the abnormal case by the aforementioned axial extension of the push rod 5 overall, even with the belt drive 3 stationary, the respective one Sliding door leaf in its open position shown in Figure 2 be moved.

Nachfolgend wird auf den weiteren Detailaufbau der Schubstange eingegangen.The following is the further detailed structure of the push rod received.

Gemäß den nachfolgenden Figuren besteht die Schubstange 5 aus einem im Querschnitt U-förmigen Schubstangen-Grundelement 5a, welches im gezeigten Ausführungsbeispiel aus zwei im Querschnitt L-förmigen und symmetrisch zueinander gebildeten und entsprechend zusammengesetzten Schalenteilen 5' und 5" besteht (Figuren 10 bis 15).According to the following figures, the push rod 5 from a push rod basic element with a U-shaped cross section 5a, which in the exemplary embodiment shown consists of two L-shaped in cross section and formed symmetrically to each other and correspondingly assembled shell parts 5 'and 5 "(Figures 10 to 15).

Entsprechend der Darstellung gemäß den Figuren 5 bis 8 und 10 bis 15 ergibt sich, daß von der Ausfahrseite des Schubstangen-Grundelementes 5a her (an welche im Abnormbetrieb das Schubstangen-Stellelement 5b durch den Hilfsantrieb ausgefahren wird) das im gezeigten Ausführungsbeispiel im Querschnitt rechteckförmig gestaltete Schubstangen-Stellelement 5b unter Spannung und Mitnahme der gummielastischen Schlaufe 13 und unter Dehnung des gummielastischen Seilzuges 15 in das Schubstangen-Grundelement 5a eingeschoben werden kann. Dabei ist entsprechend der Querschnittsdarstellung gemäß den Figuren 11 bis 15 das Schubstangen-Grundelement 5a so gestaltet, daß das Schubstangen-Stellelement 5b durch seitliche Führungsflächen 19 und eine nach unten weisende Führungsfläche 21 lediglich axial verschiebbar geführt ist.According to the representation according to Figures 5 to 8 and 10 to 15 results in that from the exit side of the Push rod base element 5a ago (to which in the abnormal operation the push rod actuator 5b by the auxiliary drive is extended) in the embodiment shown Push rod actuator with a rectangular cross section 5b under tension and driving the rubber elastic Loop 13 and stretching the rubber elastic Cable 15 in the push rod base element 5a can be inserted. This corresponds to the cross-sectional representation 11 to 15, the push rod base element 5a designed so that the push rod actuator 5b by lateral guide surfaces 19 and a downward facing guide surface 21 only axially is guided.

Im unteren Bereich des Schubstangen-Grundelementes 5a ist seitlich von den mit den Führungsflächen 19 versehenen Führungsansätzen 27 ein Freiraum gebildet, der von seiner Abmessung so gestaltet ist, daß in ihm gerade der gummielastische Seilzug 15 von den vorderen Umlenkrollen 11 kommend im Inneren des Schubstangen-Grundelementes 5a bis zur rückwärtigen Schlaufe 13 verlegt werden kann, wobei die rückwärtige Schlaufe 13 des gummielastischen Seilzuges 15 die rückwärtige Stirnseite des Schubstangen-Stellelementes 5b stets sicher umgreift und dadurch das Schubstangen-Stellelement 5b mit der Kraft des gummielastischen Seilzuges 15 druckbeaufschlagt.In the lower area of the push rod base element 5a laterally from those provided with the guide surfaces 19 Guide approaches 27 formed a free space by his Dimension is designed so that it is just the rubber elastic Cable 15 from the front pulleys 11 coming inside the push rod base element 5a to can be moved to the rear loop 13, wherein the rear loop 13 of the rubber-elastic cable 15 the rear end of the push rod actuator 5b always grips securely and thereby the push rod adjusting element 5b with the power of rubber elastic Cable 15 pressurized.

In dem oberhalb der Führungsansätze 27 liegenden Halbraum in dem Schubstangen-Grundelementes 5a sind von den in Ausfahrrichtung vorne liegenden Umlenkrollen 11 die beiden Abschnitte des gummielastischen Seilzuges 15 bis zu den erwähnten rückwärtigen Seilbefestigungspunkten 9 geführt (Figuren 8 und 9). In den Figuren 5 bis 9 und Figur 11 im Querschnitt sind Seilbefestigungseinrichtungen 9 bzw. 29 für die beiden Enden des gummielastischen Seilzuges 15 gezeigt. Über eine mittels zweier Schrauben 31 festdrehbare Spannplatte 33 können die Seilenden fest verspannt werden. Die Spannplatte 33 ist dabei Teil einer nachfolgend noch erläuterten Seilüberwachungseinrichtung.In the half space above the guide lugs 27 in the push rod base element 5a are of the in Extending direction lying front pulleys 11 the two Sections of the rubber-elastic cable 15 to the mentioned rear rope attachment points 9 performed (Figures 8 and 9). In Figures 5 to 9 and Figure 11 in Cross-section are rope fastening devices 9 and 29, respectively for the two ends of the elastic cable 15 shown. Via a screw which can be tightened by means of two screws 31 Clamping plate 33 can firmly clamp the rope ends become. The clamping plate 33 is part of a subsequent one still explained rope monitoring device.

Die Verspannung erfolgt aber nicht fest an dem Grundelement 5a, sondern fest an einem gegenüber dem Schubstangen-Grundelement 5a an dessem rückwärtigen Ende über einen gewissen Axialweg relativ verstellbaren und die Spannplatte 33 umfassenden Auslöseschlitten 35, auf dessen Bedeutung später noch eingegangen wird.However, the bracing is not fixed to the base element 5a, but firmly on one opposite the push rod base element 5a at its rear end over a certain axial travel relatively adjustable and the clamping plate 33 comprehensive trigger slide 35, on its importance will be discussed later.

Anhand der Figuren 16 bis 19 wird erläutert, wie der Hilfsantrieb unter Spannung des gummielastischen Seilzuges 15 in seine gespannte Position gebracht wird. Zum Spannen der relativ verfahrbaren Schubstange 5b wird das axial verfahrbare Schubstangen-Stellelement 5b von der stirnseitigen Einstecköffnung im Bereich der Umlenkrollen 11 unter Mitnahme der gummielastischen Schlaufe 13 in das Schubstangen-Grundelement 5a eingeschoben. Im rückwärtigen Bereich der Schubstange ist - wie sich insbesondere aus den Figuren 16 bis 19 ergibt - eine um eine horizontale und quer zur Längsrichtung der Schubstange verlaufende Achse frei drehbare Verriegelungsrolle 37 in einem Käfig drehbar gehalten. Der Käfig 39 für die Verriegelungsrolle 37 umfaßt einen Querschlitz 41 in einem rückwärtigen Bereich 43 des Schubstangen-Grundelementes 5a.16 to 19 explain how the Auxiliary drive under tension of the elastic cable 15 is brought into its cocked position. For tensioning the relatively movable push rod 5b becomes axial movable push rod actuator 5b from the front Insert opening in the area of the deflection rollers 11 below Carrying the rubber-elastic loop 13 into the push rod basic element 5a inserted. In the rear area the push rod is - as can be seen in particular from the Figures 16 to 19 results - one around a horizontal and Axis running transversely to the longitudinal direction of the push rod freely rotatable locking roller 37 rotatable in a cage held. The cage 39 for the locking roller 37 comprises a transverse slot 41 in a rear region 43 of the push rod base element 5a.

Der Durchmesser der Verriegelungsrolle 37 ist größer als die Dicke des rückwärtigen Bereiches 43 des Schubstangen-Grundelementes 5a. An den gegenüberliegenden Stirnseiten der Verriegelungsrolle 37 sitzen Zapfen 45, worüber die Verriegelungsrolle 37 unverrutschbar sitzt (Figur 15).The diameter of the locking roller 37 is larger than the thickness of the rear portion 43 of the push rod base 5a. On the opposite faces the locking roller 37 sit pin 45, about which Locking roller 37 sits non-slip (Figure 15).

In Einschubstellung - wenn also das Schubstangen-Stellelement 5b in das Schubstangen-Grundelement 5a eingeschoben ist - befindet sich eine den Querschlitz 41 in der Grundstellung überdeckende Schieberplatte 47a in der in Figur 16 gezeigten Stellung, bei der ein in der Schieberplatte 47a eingebrachter weiterer Durchtrittsschlitz 49 in Draufsicht oberhalb des im rückwärtigen Bereich 43 des Schubstangen-Grundelementes 5a eingebrachten Querschlitzes 41 zu liegen kommt.In the retracted position - if the push rod actuator 5b inserted into the push rod base element 5a is - there is a transverse slot 41 in the Basic position overlapping slide plate 47a in the in Figure 16 shown position, in which one in the slide plate 47a introduced further passage slot 49 in Top view above in the rear area 43 of the Push rod base element 5a introduced transverse slot 41 comes to rest.

Beim Einstecken des Schubstangen-Stellelementes 5b wird - wenn das vorlaufende Ende der Schubstange die Verriegelungswalze 37 erreicht - diese in die in Figur 16 gezeigte Stellung angehoben, bei der die Walze in dem aus dem Durchtrittsschlitz 49 und dem Querschlitz 41 gebildeten Hohlraum zu liegen kommt. Aus der Darstellung ist ersichtlich, daß die Gesamthöhe des Querschlitzes 41 und des Durchtrittschlitzes 49 dem Durchmesser der Walze 37 entspricht oder geringfügig größer ist.When the push rod actuator 5b is inserted, if the leading end of the push rod the locking roller 37 reached - this in that shown in Figure 16 Position raised in which the roller in the from the Passage slot 49 and the transverse slot 41 formed Cavity comes to rest. From the illustration it can be seen that the total height of the transverse slot 41 and the Pass-through slot 49 corresponds to the diameter of the roller 37 or slightly larger.

Beim weiteren Einschieben des Schubstangen-Stellelementes 5b fällt dann die Verriegelungswalze 37 mit einem Teildurchmesserbereich in eine auf der Oberseite des Schubstangen-Stellelementes 5b ausgebildete Verriegelungsvertiefung 51 ab, deren Höhe in etwa der Dicke der Schieberplatte 47a entspricht. Die Verriegelungsvertiefung 51 ist in Form einer Ausfräsung gestaltet, die in Schubrichtung vor- und nachlaufend mit einer Abschrägung, d.h. mit einer von einem Stufenabsatz abweichenden Anstiegsflanke, versehen ist.When pushing in the push rod actuator 5b, the locking roller 37 then falls with a partial diameter range into one on the top of the push rod actuator 5b trained locking recess 51, the height of which is approximately the thickness of the slide plate 47a corresponds. The locking recess 51 is designed in the form of a cutout in the direction of thrust leading and trailing with a bevel, i.e. with a rising edge deviating from a step paragraph is.

Damit der walzenförmige Verriegelungskörper 37 in dem erwähnten Käfig auch dann gehalten wird, wenn das Schubstangen-Stellelement 5b ausgefahren ist, ist vorgesehen, daß die Axiallänge der Verriegelungswalze 37 größer ist als die Breite des Schubstangen-Stellelementes 5b und damit größer als der durch die beiden gegenüberliegenden Gleitflächen 19 gebildete Abstandsraum im Schubstange-Grundelement 5a. Dabei ist ferner unterhalb der Verriegelungswalze 37 in den gegenüberliegenden Wandabschnitten 5', 5" des Schubstangen-Grundelementes 5a eine weitere, eine Vertiefung ergebende Ausfräsung 52 eingebracht, die in etwa der Tiefe der Ausfräsung 51 im Schubstangen-Stellelement 5b entspricht. Bei ausgefahrenem Schubstangen-Stellelement 5b ruht damit die Verriegelungswalze 37 mit ihren Mantelabschnitten benachbart zu ihren Stirnseiten auf den erwähnten Ausfräsungen 52. Diese Ausfräsungen 52 sind in der Querschnittsdarstellung gemäß Figur 15 sichtbar. So that the roller-shaped locking body 37 in the mentioned cage is held even when the push rod actuator 5b is extended, that the axial length of the locking roller 37 is greater than the width of the push rod actuator 5b and thus larger than that of the two opposite Sliding surfaces 19 formed space in the push rod base element 5a. It is also below the locking roller 37 in the opposite wall sections 5 ', 5 "of the push rod base element 5a is another, a recess 52 resulting in a recess, which approximately the depth of the cutout 51 in the push rod actuator 5b corresponds. With the push rod actuator extended 5b, the locking roller 37 rests with it their jacket sections adjacent to their end faces on the mentioned cutouts 52. These cutouts 52 are visible in the cross-sectional view according to FIG. 15.

Bei weiterem Eindrücken des Schubstangen-Stellelementes 5b wird nunmehr der Schieber 47 und damit die Schieberplatte 47a mit seiner stirnseitig vorgesehen, senkrecht zur Vorschubbewegung ausgerichteten Ankerplatte 53 bis zur Anlage an einen elektrischen Haftmagnet 55 vorbewegt. Dazu ist ein Mitnehmerstift 57 vorgesehen, der auf der Schieberplatte 47 sitzt und nach unten bis in Höhe des Schubstangen-Stellelementes 5b vorragt (Figur 18). Dabei ist aus dem erläuterten Aufbau auch ersichtlich, daß der Schieber 47, wie in der Zeichnung dargestellt ist, am Ende des Schubstangen-Grundelementes 5a sitzt und so verankert ist, daß dieser lediglich um einen Axialweg relativ zum Schubstangen-Grundelement 5a verstellt werden kann.When pushing in the push rod actuator 5b is now the slide 47 and thus the slide plate 47a with its end face, perpendicular to the feed movement aligned anchor plate 53 to the system moved to an electric holding magnet 55. Is to a driver pin 57 is provided on the slide plate 47 sits and down to the level of the push rod actuator 5b protrudes (Figure 18). It is over the structure described also shows that the slide 47, as shown in the drawing, at the end of Push rod base element 5a sits and is anchored so that this only by an axial path relative to the push rod base element 5a can be adjusted.

In dieser in Figur 19 gezeigten Stellung hält der Haftmagnet 55 die Ankerplatte 53 mit dem Schieber 47 in der verriegelten Stellung.The holding magnet holds in this position shown in FIG. 19 55 the anchor plate 53 with the slide 47 in the locked position.

Nach dem Loslassen des Schubstangen-Stellelementes 5b wird dies allerdings durch den erwähnten gummielastischen Seilzug 15 wiederum vom Haftmagnet 55 weggedrückt, allerdings nur bis in die in Figur 19 gezeigte Verriegelungsstellung. Denn durch die zuvor erfolgte Verschiebung und Mitnahme des Schiebers 47 kommt der in der Schieberplatte 47a vorgesehene Durchtrittsschlitz 49 versetzt zu dem Querschlitz 41 in der Deckplatte 43 zu liegen, so daß nunmehr die Schieberplatte 47a den Querschlitz 41 in der auf dem Schubstangen-Grundelement 5a fest und unverschieblich verankerten Deckplatte oben überdeckt und geschlossen hält, so daß die Verriegelungswalze 37 nicht nach oben hin aus der in Form einer Ausfräsung gebildeten Verriegelungsvertiefung 51 im Schubstangen-Stellelement 5b herausgedrängt werden kann. After releasing the push rod actuator 5b however, this is due to the rubber-elastic cable mentioned 15 again pushed away from the holding magnet 55, however only up to the locking position shown in FIG. 19. Because of the postponement and taking away of the slide 47 comes the one provided in the slide plate 47a Passage slot 49 offset to the transverse slot 41 to lie in the cover plate 43, so that now the Slider plate 47a the transverse slot 41 in the on the Push rod base element 5a fixed and immovable anchored cover plate covered at the top and closed stops, so that the locking roller 37 does not go up from the locking recess formed in the form of a cutout 51 pushed out in the push rod actuator 5b can be.

Aus dem geschilderten Einstellmechanismus geht auch hervor, daß die Länge der Verriegelungsvertiefung 51 derart ist, daß eine Vorschub- und Mitnahmebewegung des Schiebers 47 von der in den Figuren 16 und 17 gezeigten Stellung (Entriegelungsstellung) bis zu der in den Figuren 18 und 19 gezeigten Verriegelungsstellung ermöglicht wird.The adjustment mechanism described also shows that the length of the locking recess 51 such is that a feed and take-along movement of the slide 47 from the position shown in Figures 16 and 17 (Unlocking position) up to that in FIGS. 18 and 19 locking position shown is enabled.

Würde in einem Abnormbetrieb der Strom ausfallen, so würde der Haftmagnet 55 sofort abgeschaltet sein, worüber der Schieber 47 und damit die Schieberplatte 47a von ihrer in Figur 19 in die in den Figuren 16 und 17 gezeigte Stellung aufgrund der in den Figuren 6 bis 8 gezeigten Schieber-Zugfedern 59 zurückgezogen werden, mit der Folge, daß in dieser, wie in der in den Figuren 16 und 17 gezeigten Entriegelungsstellung, nunmehr das Schubstangen-Stellelementes 5b durch die Kraft des gummielastischen Seilzuges 15 unter Herausdrängung der Verriegelungswalze 37 aus der Verriegelungsvertiefung 51 sofort ausfährt.If the power would fail in an abnormal operation, it would the holding magnet 55 must be switched off immediately, via which the Slide 47 and thus the slide plate 47a from its in Figure 19 in the position shown in Figures 16 and 17 due to the slide tension springs shown in Figures 6 to 8 59 are withdrawn, with the result that in this as in that shown in Figures 16 and 17 Unlocking position, now the push rod actuator 5b by the force of the elastic cable 15 while pushing out the locking roller 37 immediately moves out of the locking recess 51.

Aus dem geschilderten Aufbau ist ersichtlich, daß die Verriegelung des ausfahrbaren Schubstangen-Stellelementes 5b mechanisch erfolgt, und zwar mittels eines im gezeigten Ausführungsbeispiel in Form einer Verriegelungswalze 37 ausgebildeten Verriegelungskörpers, wobei die Auslösung und Freigabe dieser mechanischen Verriegelung mittels einer magnetischen Betätigungseinrichtung durchgeführt wird. Dadurch müssen durch den Haftmagneten nur geringe Kräfte aufgebracht werden, um nämlich den Schieber 47 entgegen der Kraft der Schiebe-Zugfeder 59 in Verriegelungsstellung zu halten. Die eigentlichen von dem gummielastischen Seilzug 15 auf das verfahrbare Schubstangen-Stellelement 5b eingeleiteten Zugkräfte des Hilfsantriebes werden durch die mechanische Verriegelungseinrichtung aufgenommen und abgestützt.From the structure described it can be seen that the Locking of the extendable push rod actuator 5b takes place mechanically, namely by means of one shown in Embodiment in the form of a locking roller 37 trained locking body, the triggering and release of this mechanical locking means performed a magnetic actuator becomes. This means that only a small amount has to be used with the holding magnet Forces are applied, namely the slide 47 against the force of the slide tension spring 59 in the locking position to keep. The actual of the rubber elastic Cable 15 on the movable push rod actuator 5b initiated tensile forces of the auxiliary drive are taken up by the mechanical locking device and supported.

Wie anhand der Figuren 6 bis 9 auch ersichtlich ist, umfaßt das Ausführungsbeispiel auch eine Seilüberwachungseinrichtung 61. Nicht nur bei einem Riß des gummielastischen Seilzuges 15, sondern auch dann, wenn die Vorspannkraft unter einen voreinstellbaren Wert fällt, wird automatisch die Schiebetür auch bei nicht bewegten Riemenantrieb in Öffnungsstellung verfahren werden.As can also be seen from FIGS. 6 to 9, includes the embodiment also a rope monitoring device 61. Not only if the rubber elastic breaks Cable 15, but also when the biasing force falls below a preset value, will automatically the sliding door even when the belt drive is not moving be moved into the open position.

In den Figuren 6 und 7 ist dabei ferner wiederum das Ende des in das Schubstangen-Grundelement 5a eingesteckten und im gespannten Zustand gezeigten Schubstangen-Stellelementes 5b in verriegelter Stellung dargestellt.In Figures 6 and 7, the end is also again of the inserted in the push rod base element 5a and Push rod actuator shown in the tensioned state 5b shown in the locked position.

Dazu ist ferner an der oben bereits erwähnten und zur Seilüberwachungseinrichtung 61 gehörenden Spannplatte 33 ein Seilüberwachungsschalter 63 angebracht. Dieser Seilüberwachungsschalter 63 wird durch einen im Schubstangen-Grundelement 5a nach oben vorstehenden Stift 33a in seine betätigte Stellung geschaltet, in der der elektrische Haftmagnet 55 über eine über den Überwachungsschalter 63 führende und nicht näher dargestellte elektrische Leitung mit Spannung versorgt wird. In dieser in den Figuren 6 und 7 gezeigten Stellung ist die Verriegelungsrolle 37 ebenfalls wieder im Eingriff mit dem verfahrbaren Schubstangen-Stellelement 5b und damit verriegelt.For this purpose is also on the above and Rope monitoring device 61 belonging clamping plate 33 a rope monitoring switch 63 is attached. This rope monitoring switch 63 is by a basic element in the push rod 5a upwardly projecting pin 33a in its actuated position in which the electrical Holding magnet 55 via a via the monitoring switch 63 leading and not shown electrical line is supplied with voltage. In this in Figures 6 and 7 position is the locking roller 37 also again in engagement with the movable push rod actuator 5b and thus locked.

Die beiden den Schieber 47 unter Zugspannung setzenden Zugfedern 59 haben insoweit eine Doppelfunktion. Zum einen dienen sie nicht nur zur Umschaltung des Schiebers bei abfallendem Haftmagnet (also bei Stromausfall), sondern sie dienen gleichzeitig auch zur Seilüberwachung, indem sie der Gummikraft entgegenwirken. Denn die nach Art eines weiteren Schiebers ausgebildete und auf dem Schubstangen-Grundelement 5a nur um einen bestimmten Axialweg längs verschiebbare und nach Art eines Auslöseschlittens gebildete Seilüberwachungseinrichtung 61 wird nicht über separate Zugfedern, sondern über die bereits erwähnten gemeinsamen Zugfedern 59 abgestützt, worüber der Schieber 47 und die nach Art eines Schiebers gebildete Seilüberwachungseinrichtung 61 aufeinander zu vorgespannt gehalten sind.The two put the slide 47 under tension Tension springs 59 have a double function in this respect. On the one hand they are not only used to switch the slide falling holding magnet (i.e. in the event of a power failure), but they also serve for rope monitoring by they counteract the rubber force. Because the kind of further slide trained and on the push rod base element 5a only along a certain axial path displaceable and formed in the manner of a trigger slide Rope monitoring device 61 is not separate Tension springs, but over the already mentioned common Tension springs 59 supported, over which the slide 47 and the rope monitoring device formed in the manner of a slider 61 are held too biased towards each other.

Läßt nun die Seilspannung nach, so wird der erwähnte Auslöseschlitten 35 mit der Spannplatte 33 durch die Zugfedern 59 zurückgezogen (in Richtung Haftmagnet 55), so daß darüber der über den Seilüberwachungsschalter 63 mit dem elektrischen Haftmagnet geschlossene Stromkreis unterbrochen wird (Figuren 8 und 9). Dadurch fällt der Haftmagnet ab. Dadurch wird als nächstes wiederum durch die gleichen erwähnten Zugfedern 59 nunmehr der Schieber 47 vom Haftmagnet zurückgezogen, wodurch die mechanische Verriegelung des Schubstangen-Stellelementes 5b aufgehoben wird. Denn nunmehr kann die Verriegelungsrolle 37 wieder frei nach oben in den Ausweich- und Freigabeschlitz 49 angehoben werden, wodurch der bewegbare, ausfahrbare Teil der Schubstange, nämlich das Schubstangen-Stellelement 5b ausgefahren und darüber der ihm zugeordnete Schiebetürflügel 1 in Öffnungsstellung verschoben wird.If the rope tension now subsides, the above-mentioned release slide becomes 35 with the clamping plate 33 by the tension springs 59 withdrawn (in the direction of the holding magnet 55), so that above that via the rope monitoring switch 63 with the electric holding magnet closed circuit interrupted will (Figures 8 and 9). This will cause the magnet to drop from. This will turn through the next same slide springs 59 mentioned now the slide 47th withdrawn from the holding magnet, causing the mechanical Locking of the push rod actuator 5b released becomes. Because now the locking roller 37 can again freely upwards into the escape and release slot 49 be raised, causing the movable, extendable part the push rod, namely the push rod actuator 5b extended and above it the assigned sliding door leaf 1 is moved to the open position.
