Abstract

1. Folding door with a support frame and an elastic panel (2) fixed therein, where at least one folding zone is provided on the horizontal strut (1, 1') of the frame, where the elastic panel (2) is made of a single piece and exhibits a vertical flexing area (5) with an increased bending elasticity in the vicinity of the folding zone (4), characterized in that the door activator comprises a rotating motor which has a vertical axis shifted with respect to the plane of the door and which is positioned above the sweeping arc of the folding door, where this motor urges a swinging arm (13), the sweeping end of which is slindingly engaged in a rail (14) running longitudinally along the upper, horizontal strut of the frame of the inner panel of the door in order to swing the same, where, in its two end positions, the swinging arm (13) is essentially normal to the surface of the frame.

Description

Die Erfindung betrifft eine Falttüre mit Tragrahmen und darin befestigter, elastischer Füllung, wobei am horizontalen Rahmenschenkel mindestens eine Faltstelle vorgesehen ist. Besonders im industriellen Bereich finden seit langem Pendeltüren Anwendung, die elastische Türfüllungen aus durchsichtigem Kunststoff besitzen und die für Fahrzeuge befahrbar sind, wobei sie sich jeweils in der Fahrtrichtung öffnen. Obwohl sich solche Pendeltüren im allgemeinen gut bewähren, treten in besonderen Fällen gewisse Nachteile auf. Soll etwa eine Pendeltüre zusammen mit einem Brandschutztor installiert werden, so besteht die Gefahr, dass ein offenstehender Flügel der Pendeltüre das Schliessen des Brandschutztores behindert. Dies kann zwar durch bloss einseitiges Öffnen der Pendeltüre verhindert werden, was aber aus Sicherheitsgründen unerwünscht ist, weil sich die Türe dann gegen eine der Fahrtrichtungen öffnen muss. Zudem muss in dieser Fahrtrichtung jeweils das vollständige Öffnen der Türe abgewartet werden. Auch für grosse Türöffnungen ergeben sich bei Pendeltüren der genannten Art gewisse Grenzen. Neben erheblichem, seitlichen Platzbedarf sind es vor allem die grossen Massen und Flächen der Türflügel, welche an den Antrieb besondere Anforderungen stellen und die Öffnungsgeschwindigkeit begrenzen. Zudem stellen solche Pendeltüren wegen ihres grossen Schwenkradius eine potentielle Gefahrenquelle für Personen dar.The invention relates to a folding door with a supporting frame and an elastic filling fastened therein, at least one folding point being provided on the horizontal frame leg. Swing doors have long been used, particularly in the industrial sector, which have elastic door panels made of transparent plastic and which can be driven on by vehicles, each opening in the direction of travel. Although such swing doors generally work well, there are certain disadvantages in special cases. If, for example, a swing door is to be installed together with a fire door, there is a risk that an open wing of the swing door will prevent the fire door from closing. This can be prevented by simply opening the swing door on one side, but this is undesirable for safety reasons because the door must then open against one of the directions of travel. In addition, the door must be fully opened in this direction of travel. There are also certain limits for swing doors of the type mentioned, even for large door openings. In addition to considerable lateral space requirements, it is above all the large masses and areas of the door leaves that place special demands on the drive and limit the opening speed. In addition, because of their large swivel radius, such swing doors represent a potential source of danger for people.

Es ist versucht worden, diese Probleme durch Falttore zu lösen, wie sie aus der DE-A 33 29 713 bekannt geworden sind. Das dabei verwendete Falttorblatt besteht über die ganze Breite des Torflügels aus einer elastischen Folie, die zwischen den Faltstellen vertikale Bahnen aus weniger elastischem Kunststoff besitzt, so dass ein winddichter Abschluss erzielt werden kann. Der Antrieb des Falttores erfolgt über einen motorgetriebenen Kettenzug. Für jede Bahn ist ein Laufwagen vorgesehen. Die Laufwagen werden durch den Kettenzug in einer horizontalen Führungsschiene hin- und herbewegt. Diese Antriebsart ist konstruktiv aufwendig, da über die gesamte Torbreite ein Kettenzug verläuft. Die Öffnungsgeschwindigkeit ist durch die Zugfestigkeit des Kettenzuges beschränkt. Im geöffneten Zustand müsste eine separate Bremse vorgesehen werden, um das selbsttätige Schliessen des Tores durch die elastischen Kräfte des gefalteten Torflügels zu verhindern.Attempts have been made to solve these problems by means of folding gates such as are known from DE-A 33 29 713. The folding door leaf used here consists of an elastic film over the entire width of the door leaf, which has vertical sheets of less elastic plastic between the folding points, so that a windproof closure can be achieved. The folding door is driven by a motorized chain hoist. A carriage is provided for each track. The carriage is moved back and forth by the chain hoist in a horizontal guide rail. This type of drive is structurally complex because a chain hoist runs across the entire door width. The opening speed is limited by the tensile strength of the chain hoist. When opened, a separate brake would have to be provided in order to prevent the door from closing automatically due to the elastic forces of the folded gate leaf.

In der Publikation DE-B 22 54 231 ist andererseits eine Antriebsvorrichtung zum Öffnen und Schliessen von Türen mittels einer Hebelanordnung beschrieben. Dieser Antrieb, der vor allem für Kipptore vorgesehen ist, beansprucht viel Raum ausserhalb des Schwenkbereiches der Türen. Er ist deshalb insbesondere für industrielle Anwendungen nicht geeignet.On the other hand, the publication DE-B 22 54 231 describes a drive device for opening and closing doors by means of a lever arrangement. This drive, which is primarily intended for up-and-over doors, takes up a lot of space outside the swivel range of the doors. It is therefore particularly unsuitable for industrial applications.

Auf dem Hintergrund dieses Standes der Technik stellt sich die Aufgabe, eine Falttüre der eingangs genannten Art zu schaffen, welche die erwähnten Nachteile nicht besitzt, zugleich aber die für die bekannten Pendeltüren charakteristischen Vorteile beibehält.Against the background of this prior art, the task arises of creating a folding door of the type mentioned at the outset, which does not have the disadvantages mentioned, but at the same time retains the advantages which are characteristic of the known swing doors.

Dies wird bei einer Falttüre der eingangs erwähnten Art durch die Merkmale gemäss Patentanspruch 1 erreicht.This is achieved in a folding door of the type mentioned by the features according to claim 1.

Vorzugsweise ist die Biegezone durch einen, mit den benachbarten Füllungsteilen fest verbundenen, sich im wesentlichen über die gesamte Höhe der Türfüllung erstreckenden, elastischen Streifen gebildet.The bending zone is preferably formed by an elastic strip which is firmly connected to the adjacent panel parts and extends essentially over the entire height of the door panel.

Da sich Falttüren, anders als Pendeltüren, nicht von den Zufahrtsrichtungen weg öffnen, ist ein relativ rasches seitliches Weichen der Türflügel erwünscht, wobei aber gegen die Endlagen hin eine Abbremsung erfolgen soll. Dies ist insbesondere beim Schliessvorgang nötig, da die einstükkigen elastischen Füllungen in der Schliessrichtung erhebliche Scherkräfte entfalten können. Jedenfalls beim Schliessen sollte demnach die letzte Phase aus Gründen der Sicherheit verlangsamt ablaufen. Der erfindungsgemässe Türantrieb besitzt den Vorteil, dass zufolge seiner Konstruktion beim Öffnen und Schliessen der Tür die Schwenkgeschwindigkeit der Türflügel jeweils in einem ersten Winkelbereich gesteigert und in einem zweiten Winkelbereich bis in die Endlage wieder herabgesetzt wird, wenn der Drehmotor mit gleichförmiger Drehgeschwindigkeit angetrieben wird. Zudem bewirkt der Eingriff des Schwenkhebels am Tragrahmen der Falttüre, dass die Türe selbsttätig in geschlossenem bzw. geöffnetem Zustand gehalten ist. Damit wird die Türe in geschlossenem Zustand selbsttätig gegen Winddruck gesichert.Since folding doors, unlike swing doors, do not open away from the direction of access, a relatively quick lateral wiping of the door leaves is desirable, but braking should take place towards the end positions. This is particularly necessary during the closing process, since the one-piece elastic fillings can develop considerable shear forces in the closing direction. In any case, when closing the last phase should slow down for security reasons. The door drive according to the invention has the advantage that, due to its construction, when opening and closing the door, the pivoting speed of the door leaves is increased in a first angular range and is reduced again in a second angular range to the end position when the rotary motor is driven at a uniform rotational speed. In addition, the engagement of the pivot lever on the support frame of the folding door means that the door is automatically held in the closed or open state. In this way, the door is automatically secured against wind pressure when closed.

Nachfolgend wird anhand der beiliegenden Zeichnungen ein entsprechendes Ausführungsbeispiel der Erfindung näher beschrieben. Es zeigen:

  • Fig. 1 eine Falttüre gemäss der Erfindung in Frontansicht;
  • Fig. 2 einen Schnitt durch die Biegezone der elastischen Türfüllung;
  • Fig. 3 eine Aufsicht auf den Türantrieb des einen Flügels in der geschlossenen Lage mit strichliert angedeuteter, offener Position, und
  • Fig. 4a bis 4c drei Positionen der Hebelanordnung des Türantriebes in schematischer Darstellung.
A corresponding exemplary embodiment of the invention is described in more detail below with reference to the accompanying drawings. Show it:
  • Figure 1 is a folding door according to the invention in a front view.
  • 2 shows a section through the bending zone of the elastic door panel;
  • Fig. 3 is a plan view of the door drive of a wing in the closed position with dashed lines, open position, and
  • 4a to 4c three positions of the lever arrangement of the door drive in a schematic representation.

In Fig. 1 ist zunächst eine Gesamtansicht der Falttüre mit Tragrahmen und elastischer Füllung 2 gezeigt. Der horizontale Rahmenschenkel 1, 1' weist eine Faltstelle 4 auf, während sich die Türvorderkante im wesentlichen längs dem Türsturz bewegt und in einer entsprechenden Führung 7 geführt sein kann. Ein Antrieb 3 wirkt auf den inneren Rahmenschenkel 1 und verschwenkt diesen zwischen der geschlossenen und der offenen Position, wie noch im einzelnen beschrieben wird. Um das einwandfreie Schliessen aus der offenen Position sicherzustellen, ist eine Zwangsfaltungseinrichtung 4, 15, 16 vorgesehen, welche bei der Verschwenkung des inneren Rahmenschenkels 1 zwangsweise eine gegensinnig gleiche Verschwenkung des äusseren Rahmenschenkels 1' bewirkt und die ebenfalls noch näher erläutert wird. Die Türfüllung 2 ist als ein Stück ausgebildet und am Tragrahmen mittels der in CH-PS 2 424 180 beschriebenen Einrichtung befestigt. Im Bereich der Faltstelle 4 besitzt die elastische Füllung eine vertikale Biegezone erhöhter Biegeelastizität, die durch einen, mit den benachbarten Füllungsteilen 6 fest verbundenen, sich im wesentlichen über die gesamte Höhe der Türfüllung erstreckenden, elastischen Streifen 5 gebildet ist, wie sich insbesondere aus Fig. 2 entnehmen lässt. Vorzugsweise bestehen sowohl die Füllungsteile 6 als auch der Streifen 5 aus Weich-PVC, wobei der Streifen 5 durch Kaltverschweissung mit den Füllungsteilen 6 verbunden wird. Die Füllungsteile 6 weisen dabei beispielsweise eine Dicke von 7 mm auf, während die Dicke des Streifens 5 1 mm beträgt. Damit kann eine einwandfreie Faltung der elastischen Türfüllung längs des Bereiches mit der grössten Biegeelastizität sichergestellt werden. Obschon die Unterseite der Türfüllung nicht geführt ist, sondern frei hängt, findet bei dieser Ausgestaltung auch dort eine einwandfreie Faltung statt.In Fig. 1, an overall view of the folding door with a support frame and elastic filling 2 is first shown. The horizontal frame leg 1, 1 'has a fold point 4, while the front edge of the door moves essentially along the lintel and can be guided in a corresponding guide 7. A drive 3 acts on the inner frame leg 1 and pivots this between the closed and the open position, as will be described in detail. In order to ensure proper closing from the open position, a forced folding device 4, 15, 16 is provided which, when the inner frame leg 1 is pivoted, inevitably causes the outer frame human to pivot in the same direction kels 1 'causes and which is also explained in more detail. The door panel 2 is designed as one piece and fastened to the support frame by means of the device described in CH-PS 2 424 180. In the area of the fold point 4, the elastic panel has a vertical bending zone of increased bending elasticity, which is formed by an elastic strip 5, which is firmly connected to the adjacent panel parts 6 and extends essentially over the entire height of the door panel, as can be seen in particular in FIG. 2 can be removed. Both the filling parts 6 and the strip 5 are preferably made of soft PVC, the strip 5 being connected to the filling parts 6 by cold welding. The filling parts 6 have, for example, a thickness of 7 mm, while the thickness of the strip 5 is 1 mm. This ensures proper folding of the elastic door panel along the area with the greatest bending elasticity. Although the underside of the door panel is not guided, but hangs freely, this embodiment also flawlessly folds there.

Der Türantrieb 3 lässt sich insbesondere den Figuren 3 und 4 entnehmen. Er ist mittels einer Halterung 12 seitlich am Türsturz über dem Schwenkbereich der Falttüre angeordnet. Ein Antriebsmotor 11 ist mit vertikaler Antriebswelle ausserhalb der Türebene plaziert und wirkt über eine Hebelanordnung 12,13 auf den inneren Türflügel.The door drive 3 can be seen in particular from FIGS. 3 and 4. It is arranged by means of a bracket 12 on the side of the lintel above the pivoting area of the folding door. A drive motor 11 is placed outside the door plane with a vertical drive shaft and acts on the inner door leaf via a lever arrangement 12, 13.

An der Antriebswelle des Motors 11 ist ein Antriebshebel 12 befestigt, der gleitend in einen Schwenkhebel 13 eingreift. Der Schwenkhebel 13 seinerseits greift gleitend in eine Längsführung 14 am inneren Rahmenschenkel ein. Wie aus Fig. 4a ersichtlich ist, stehen Antriebshebel 12, Schwenkhebel 13 und Längsführung 14 bei geschlossener Türe senkrecht zueinander und führen so zu einer selbsttätigen Fixierung, um das ungewollte Öffnen der Türe, z.B. durch Winddruck, zu verhindern. Die Hebelanordnung ist nun so getroffen, dass bei einer gleichförmigen Dreivierteldrehung der Antriebswelle des Motors eine aus dem Stillstand beschleunigte und hernach wieder bis zum Sillstand verzögerte Schwenkbewegung der Türflügel erzeugt wird. Wie aus den Fig. 4b und c ersichtlich ist, entspricht dabei das erste bzw. letzte Viertel der Motorendrehung einem relativ kleinen Schwenkwinkel, während im mittleren Viertel der Hauptteil der Schwenkung ausgeführt wird. Damit wird ein rasches Öffnen bzw. Schliessen der Falttüre erreicht, das zugleich den Sicherheitsanforderungen (langsames Schliessen im Endbereich) genügt und zu starke mechanische Beanspruchungen der Bauteile vermeidet.A drive lever 12 is fastened to the drive shaft of the motor 11 and slidably engages in a swivel lever 13. The pivot lever 13 in turn engages in a longitudinal guide 14 on the inner frame leg. As can be seen from Fig. 4a, drive lever 12, pivot lever 13 and longitudinal guide 14 are perpendicular to each other when the door is closed and thus lead to an automatic fixation in order to prevent the door from being opened unintentionally, e.g. due to wind pressure. The lever arrangement is now such that, with a uniform three-quarter turn of the drive shaft of the motor, a swivel movement of the door leaves that is accelerated from standstill and then decelerated to standstill is generated. As can be seen from FIGS. 4b and c, the first or last quarter of the motor rotation corresponds to a relatively small swivel angle, while the main part of the swivel is carried out in the middle quarter. This enables the folding door to be opened or closed quickly, which at the same time meets the safety requirements (slow closing in the end area) and avoids excessive mechanical stress on the components.

Da der Antrieb, wie beschrieben, auf den inneren Rahmenschenkel 1 wirkt, ist für den äusseren Rahmenschenkel l'eine Zwangsfalteinrichtung 4, 15, 16 vorgesehen, welche sicherstellt, dass sich bei jeder Verschwenkung des inneren Rahmenschenkels 1 der äussere um einen entsprechenden Winkel im Gegensinne verschwenkt. Die Zwangsfalteinrichtung 4, 15, 16 besteht im wesentlichen aus einer Stange 15, die zusammen mit dem inneren Rahmenschenkel 1 und einem Gelenkteil 16 ein Parallelogramm bilden, womit der Gelenkteil 16 bei der Türbewegung ausschliesslich Parallelverschiebungen ausführt (vgl. Fig. 3). Zwischen jedem Rahmenschenke! 1,1' und dem Gelenkteil 16 ist je ein Hebelpaar angeordnet, deren innere Hebel mittels Verzahnung ineinander greifen (nicht dargestellt). Wie leicht einzusehen ist, wird dadurch jede Verschwenkung des inneren Rahmenteiles 1 gegengleich auf den äusseren Rahmenteil 1' übertragen. Dies erlaubt insbesondere ein vollständiges Öffnen der Falttüre, ohne dass der äussere Rahmenteil 1' den nachfolgenden Schliessvorgang in der Anfangsphase behindert oder gar blockiert.Since the drive, as described, acts on the inner frame leg 1, a forced folding device 4, 15, 16 is provided for the outer frame leg 1 ', which ensures that each time the inner frame leg 1 is pivoted, the outer one in the opposite direction by a corresponding angle pivoted. The forced folding device 4, 15, 16 essentially consists of a rod 15, which together with the inner frame leg 1 and an articulated part 16 form a parallelogram, with which the articulated part 16 exclusively executes parallel displacements during the door movement (cf. FIG. 3). Between each frame bar! 1, 1 'and the joint part 16 each have a pair of levers, the inner levers of which engage in one another by means of teeth (not shown). As can easily be seen, each pivoting of the inner frame part 1 is thereby transferred in opposite directions to the outer frame part 1 '. In particular, this allows the folding door to be opened completely without the outer frame part 1 'hindering or even blocking the subsequent closing process in the initial phase.

Da die Phase der Beschleunigung der Schwenkbewegung beim Schliessen der Türe schon bei einem relativ steilen Winkel der Türflügel beginnt (vgl. Fig. 4c), kann auf diese Weise ferner eine übermässige Belastung der vorderen Führung 7 (Fig. 1) des äusseren Türflügels vermieden werden. Diese Führung 7 ist kinematisch an sich nicht nötig, stellt jedoch die exakte Position der Türvorderkante, insbesondere in der Endphase des Schliessvorganges, sicher.Since the phase of the acceleration of the swiveling movement when the door closes already begins at a relatively steep angle of the door leaf (see FIG. 4c), an excessive load on the front guide 7 (FIG. 1) of the outer door leaf can also be avoided in this way . This guide 7 is kinematically not necessary per se, but ensures the exact position of the front edge of the door, in particular in the final phase of the closing process.

Die beschriebene Falttüre stellt auch für grosse Öffnungsweiten ein gefahrloses und rasches Offnen und Schliessen bei geringem seitlichem Platzbedarf sicher, wobei die wesentlichen Vorteile herkömmlicher Pendeltüren erhalten bleiben. Insbesondere kann die Falttüre entsprechend bisherigen Pendeltüren mittels Fahrzeugen in beiden Richtungen gefahrlos befahren werden und bietet einen winddichten Abschluss, wobei jedoch grössere Türweiten als mit bisherigen Pendeltüren erreichbar sind. Die Installation zusammen mit Brandschutztoren bietet keinerlei Probleme.The folding door described also ensures safe and rapid opening and closing for large opening widths with a small space requirement, while maintaining the essential advantages of conventional swing doors. In particular, the folding door corresponding to previous swing doors can be driven safely in both directions by vehicles and offers a windproof closure, although larger door widths can be achieved than with previous swing doors. Installation together with fire gates does not pose any problems.
