Description

Die Erfindung bezieht sich auf ein Schiebefalttor, dessen doppelwandige Torflügel durch profilierte Verbindungs-schienen um je zwei vertikale, innerhalb der Verbindungsschienen liegende Schwenkachsen miteinander verbunden sind.The invention relates to a sliding folding door, the double-walled gate leaves are connected by profiled connections g -rails by two vertical pivot axes lying within the connecting rails.

Die vorgeschlagene Erfindung findet Anwendung bei zwei-, drei- und mehrflügeligen Schiebefalttoren für Industriehallen und Großgaragen.The proposed invention is used in two-, three- and multi-leaf sliding folding gates for industrial halls and large garages.

Angesichts zunehmender Energieverknappung und steigender Energiekosten werden die Verbindungs- bzw. Schwenkstellen zwischen den Torflügeln von Schiebefalttoren immer mehr zu einem Problem. Während es gelungen ist, die Wärmedämmung der doppelwandigen Torflügel in zufriedenstellender Weise zu verbessern, bleiben bezüglich der Spalte an den Verbindungsstellen immer noch Wünsche offen. Diese langen Spalte konnten bisher bei keiner der verschiedenen bekannten Bauarten von Schiebefalttoren befriedigend abgedichtet werden, sodaß insbesondere bei starker Luftbewegung er- hebliche Verluste an Wärmeenergie in Kauf genommen werden müssen. Der Ausbildung der Verbindungs- und Schwenkstellen der Schibefalttore wurde bisher auch unter dem Blickwinkel der Unfallgefahr häufig nicht genügende Aufmerksamkeit geschenkt. Die an eich zu stellende Forderung, saß die an diesen Stellen unvermeidlichen. Spalte in jeder Stellung der Torflügel so klein sein müssen, daß auch Kinder dort keinen Finger einklemmen können, konnte bisher oft nicht ausreichend erfüllt werden.In view of increasing energy shortages and rising energy costs, the connection or pivot points between the gate leaves of sliding folding gates are becoming an increasing problem. While it has been possible to improve the thermal insulation of the double-walled gate leaves in a satisfactory manner, wishes still remain unanswered with regard to the gaps at the connection points. These long gaps have so far not been satisfactorily sealed in any of the various known types of sliding folding doors be so especially against strong air movement ER h ebliche losses of heat energy into account must be taken. The design of the connection and pivoting points of the folding ski gates has often not been given sufficient attention from the point of view of the risk of accidents. The request to be made to me sat the inevitable in these places. Gaps in every position of the gate wing must be so small that children cannot pinch a finger there, too, has so far often not been sufficiently fulfilled.

Mit der Deutschen Patentschrift 1 509 252 ist ein mehrflügeliges Schiebefalttor bekannt geworden, bei welchem die Torflügel mittels im Querschnitt U-förmiger Deckleisten gelenkig miteinander verbunden sind, wobei die Schwenkachsen der Torflügel innerhalb des Grundrisses der Deckschienen liegen. Die dabei vorgeschlagene Ausbildung der Längsränder der Torflügel sowie der Deckschienen ist nicht geeignet, die nachteiligen Wirkungen der aus technischen Gründen erforderlichen Längsspalte zwischen den schwenkbaren Teilen zu vermeiden.German patent specification 1 509 252 discloses a multi-leaf sliding folding door in which the door leaves are hingedly connected to one another by means of cover strips of U-shaped cross section, the pivot axes of the door leaves lying within the outline of the cover rails. The proposed design of the longitudinal edges of the gate leaves and the cover rails is not suitable for avoiding the adverse effects of the longitudinal gaps between the pivotable parts which are required for technical reasons.

Der Erfindung liegt die Aufgabe zugrunde, ein Schiebefalttor so auszubilden, daß die Längsspalte an den Schwenkstellen zwischen den Torflügeln in ihrer Geschlossenstellung einwandfrei abgedichtet sind und außerdem diese Spalte in jeder Schwenkstellung der Torflügel so klein sind, daß eine Unfallgefahr ausgeschlossen ist.The invention has for its object to design a sliding folding door so that the longitudinal gaps at the pivot points between the gate leaves are properly sealed in their closed position and also these gaps are so small in each pivoting position of the gate leaves that an accident risk is excluded.

Diese Aufgabe wird an einem Schiebefalttor der eingangs beschriebenen Bauart dadurch gelöst, daß jede Verbindungsschiene zwei im Querschnitt viertelkreisförmige, sich längs der Verbindungsschiene erstreckende, mit ihren Krümmungs-Mittelpunkten in den. Schwenkachsen liegende Zylinderwandungen aufweist und jeder Zylinderwandung ein entlang der Längsseite des Torflügels angeordneter Steg gegenübersteht. Diese Zylinderwandungen konstanter Krümmung bewirken in Verbindung mit den ihnen gegenüberliegenden Stegen, daß die Spalte an den Schwenkstellen fast beliebig klein wählbar und in jeder Schwenkstellung der Torflügel gleich sind, sodaß sowohl eine ausgezeichnets Abdichtung erzielt wie die Gefahr von Unfällen vermieden wird.This object is achieved on a sliding folding door of the type described at the outset in that each connecting rail has two cross-sections which are quarter-circular in cross section and extend along the connecting rail with their centers of curvature in the. Has cylinder walls lying pivot axes and each cylinder wall opposite web arranged along the long side of the gate wing. These cylinder walls of constant curvature, in conjunction with the webs opposite them, mean that the gaps at the pivot points can be chosen almost arbitrarily small and are the same in every pivot position of the gate leaves, so that both an excellent seal is achieved and the risk of accidents is avoided.

In bevorzugter Ausgestaltung der Erfindung trägt jede Verbindungsschiene zwei weitere, viertelkreisförmige, sich längs erstreckende, mit ihren Krümmungsmittelpunkten ebenfalls in den Schwenkachsen liegende Zylinderwandungen, denen zwei weitere Stege gegenüberstehen. Mittels dieser Maßnahme wird die Abdichtung zusätzlich verbessert, weil dadurch jede SchwenkstelLe mit zwei hintereinanderliegenden Spalten ausgestattet ist, die ein Luftpolster einschließen; darüber hinaus läßt sich damit bei geeigneter Dimensionierung ein identisches Aussehen der Innen- und Außenseite des Schiebefalttores erzielen.In a preferred embodiment of the invention, each connecting rail carries two further, quarter-circular, longitudinally extending cylinder walls with their centers of curvature likewise lying in the pivot axes, which are opposed by two further webs. By means of this measure, the sealing is additionally improved, because each pivot point is equipped with two columns one behind the other, which enclose an air cushion; moreover, with a suitable dimensioning, an identical appearance of the inside and outside of the sliding folding door can be achieved.

Aus konstruktiven und optischen Gründen setzen die Stege vorteilhaft an der Außenwand bzw. der Innenwand der Torflügel an.For structural and visual reasons, the webs are advantageously applied to the outer wall or the inner wall of the gate leaves.

Die Zylinderwandungen sind durch Querstege zweckmäßig verbunden.The cylinder walls are expediently connected by crossbars.

Zwischen den Zylinderwandungen kann Dämmaterial angeordnet sein.Insulating material can be arranged between the cylinder walls.

Es ist von Vorteil, wenn längs der Stege Dichtungsbänder angeordnet sind.It is advantageous if sealing tapes are arranged along the webs.

Nach einem weiteren, wichtigen Merkmal der Erfindung legt sich das verlängerte Ende der Zylinderwandung in Geschlossenstellung der Torflügel an ein an der Innenwand bzw. der Außenwand des Torflügels befestigtes Dichtungspolster an. Dieses Dichtunsspolster dient als Anschlag zur Begrenzung der Schwenkbewegung der Torflügel in ihrer Offenstellung und sie wirkt in dieser als zusätzliche Abdichtungsmaßnahme, weil das Luftpolster zwischen den beiden hinter- einander liegenden Spalten in zwei Teile aufgeteilt wird.According to another important feature of the invention the extended end of the cylinder wall in the closed position of the door wing adjoins a sealing cushion attached to the inner wall or the outer wall of the door wing. This sealing pad serves as a stop to limit the pivoting movement of the gate leaves in their open position and acts as an additional sealing measure because the air cushion is divided into two parts between the two columns one behind the other.

Eine Aufteilung des Luftpolsters in der Schwenkstelle in drei Teile und damit eine weitere Verbesserung der Dichtungen und der Wärmedämmung kann durch eine besondere Ausbildung der Schwenkgelenke erzielt werden, indem an den Verbindungsschienen endständige Gelenkbolzen tragende Bänder angeformt sind, die sich in an der Innenwand bzw. Außenwand des Torflügels angeformten, einen Längsschlitz aufweisenden Gelenkhülsen drehen.A division of the air cushion in the swivel point into three parts and thus a further improvement of the seals and the thermal insulation can be achieved by a special design of the swivel joints, by means of hinges on the connecting rails, which are formed by hinges which carry end bolts and which are located on the inner or outer wall of the gate wing molded, having a longitudinal slot sleeves.

Die Erfindung ist in einer beispielhaften Ausführungsform in der beigefügten Zeichnung dargestellt und wird anhand dieser im Folgenden näher beschrieben. Es zeigen:

  • Figur 2 das Schiebefalttor gemäß Figur 1, in einem Horizontalschnitt, in etwas vereinfachter Darstellung, wobei eine halbgeöffnete Stellung der Torflügel mit Strichlinien wiedergegeben ist;
  • Figur 3 eine Verbindungsschiene in einem Querschnitt, entsprechend dem Detail A in Figur 2, in etwa natürlicher Größe.
The invention is shown in an exemplary embodiment in the accompanying drawing and is described in more detail below with reference to this. Show it:
  • FIG. 1 shows a three-leaf sliding folding door equipped with new connecting rails, in a front view;
  • Figure 2 shows the sliding folding door according to Figure 1, in a horizontal section, in a somewhat simplified representation, with a half-open position of the gate wing is shown with dashed lines;
  • Figure 3 shows a connecting rail in a cross section, corresponding to detail A in Figure 2, approximately natural size.

Das Schiebefalttor, welches in den Figuren 1 und 2 dargestellt ist, besteht aus drei Torflügeln 1, 2 und 3, welche in einem vertikalen Torrahmen 4 nebeneinander angeordnet sind. Die beiden Zargenpfosten 5 sowie der Zargenkampfer 6 bestehen aus Stahlprofilen und sind fest mit der Gobäudewand 7 verbunden. Im zargenkämpfer 6 ist eine Tragschiene 8 vorgesehen, in welcher Tragrollen 9 laufen, an denen die Torflügel 2 und 3 drehbar aufgehängt sind. Die drei Torflügel 1, 2 und 3 sind doppelwandig ausgebildet, wobei Außenwand 10 und Innenwand i1 aus Stahlblechen hergestellt sind, zwischen welchen ein Wärmedämmaterial vorgesehen ist. Die Innenwände 11 legen sich (vgl. Figur 2) bei geschlossenem Schiebefalttor an eine in den Boden 12 eingelassene Anschlagschiene 13 an, eine entsprechende Anschlagschiene (nicht dargestellt) befindet sich an der Unterseite des Zargenkämpfers 6.The sliding folding door, which is shown in Figures 1 and 2, consists of three door leaves 1, 2 and 3, which are arranged side by side in a vertical door frame 4. The two frame posts 5 and the frame camphor 6 consist of steel profiles and are firmly connected to the wall 7 of the building. In the door frame 6 a support rail 8 is provided, in which support rollers 9 run, on which the gate leaves 2 and 3 are rotatably suspended. The three gate leaves 1, 2 and 3 are double-walled, the outer wall 10 and inner wall i1 being made from steel sheets, between which a thermal insulation material is provided. When the sliding folding door is closed, the inner walls 11 (see FIG. 2) lie against a stop rail 13 embedded in the floor 12; a corresponding stop rail (not shown) is located on the underside of the frame member 6.

Die drei Torflügel 1, 2 und 3 sind untereinander an ihren einander gegenüberliegenden Längsseiten 14 mittels profilierter Verbindungsschienen 15 um je zwei vertikale und innerhalb dieser Verbindungsschienen 15 liegende Schwenkachsen 16 und 17 schwenkbar miteinander verbunden. Eine entsprechende Verbindungsschiene 18 befindet sich zwischen dem ersten Torflügel 1 und dem Zargenpfosten 5, wo dieser Torflügel 1 schwenkbar angeschlagen ist. Die Verbindungsschienen 15 stehen mittels in drei verschiedenen Höhen angeordneter Scharniere 19 (vgl. Figur 1) mit den Torflügeln 1, 2 und 3 schwenkbar in Verbindung. Beim Öffnen des Schiebefalttores verschieben sich die Torflügel 1, 2, und 3 in Richtung des Pfeiles 20, und gleichzeitig schwer ken die Torflügel 1, 2 und3 entsprechend den'Pfeilen 21 gegeneinander sowie aus dem Torrahmen 4 nach vorn heraus (mit Strichlinien angedeutete Stellung in Figur 2), bis sie zuletzt parallel dicht nebeneinander und senkrecht zur Ebene des Torrahmens 4 an der Gebäudewand 7 stehen.The three gate leaves 1, 2 and 3 are connected to one another on their opposite longitudinal sides 14 by means of profiled connecting rails 15 such that they can pivot about two vertical pivot axes 16 and 17 lying within these connecting rails 15. A corresponding connecting rail 18 is located between the first gate leaf 1 and the frame post 5, where this gate leaf 1 is pivotally attached. The connecting rails 15 are pivotally connected to the gate leaves 1, 2 and 3 by means of hinges 19 arranged at three different heights (cf. FIG. 1). When the sliding folding door is opened, the gate leaves 1, 2 and 3 move in the direction of the arrow 20, and at the same time the gate leaves 1, 2 and 3 are difficult to move forward and out of the door frame 4 in accordance with the arrows 21 (position indicated by broken lines in Figure 2) until they are finally parallel to each other and perpendicular to the level of the goal frame 4 on the building wall 7.

Eine neuerungsgemäße, profilierte Verbindungsschiene 15 (vgl. Figur 3) besteht aus stranggepreßtem Aluminium. Diese Verbindungsschiene 15 weist zwei im Querschnitt viertelkreisförmige Zylinderwandungen 22, 22' sowie zwei weitere Zylinderwandungen 23, 23' auf, welche ebenfalls viertelkreisförmigen Querschnitt besitzen. Alle Zylinderwandungen 22, 22' und 23, 23' erstrecken sich in Längsrichtung der Verbindungsschiene 15 und sie sind an ihren Längskanten paarweise miteinander verbunden. Bei den Zylinderwandungen 22, 22' geschieht diese Verbindung durch stetigen Übergang mittels eines geraden-Verbindungsstükkes 24, während die beiden Zylinderwandungen 23, 23' einen spitzwinkeligen, schmalen Stoß 25 miteinander bilden. Die beiden Zylinderwandungen 22 und 22' weisen an ihrer Außenseite 26 den gleichen Krümmungsradius 27 auf und ihre Krümmungsmittelpunkte 28 liegen in den Schwenkachsen 16 und 17. Die beiden weiteren Zylinderwandungen 23 und 23' besitzen an ihren Innenseiten 29 einen ebenfalls übereinstimmenden Krümmungsradius 30 und ihre Krümmungsmittelpunkte 31 liegen wiederum in den Schwenkachsen 16 und 17. Der Krümmungsradius 27 ist größer als der Krümmungsradius 30.A profiled connecting rail 15 according to the innovation (see FIG. 3) consists of extruded aluminum. This connecting rail 15 has two cylinder walls 22, 22 'which are quarter-circular in cross section and two further cylinder walls 23, 23' which also have a quarter-circular cross-section. All cylinder walls 22, 22 'and 23, 23' extend in the longitudinal direction of the connecting rail 15 and they are connected to one another in pairs on their longitudinal edges. In the case of the cylinder walls 22, 22 ', this connection takes place through a continuous transition by means of a straight connecting piece 24, while the two cylinder walls 23, 23' form an acute-angled, narrow joint 25 with one another. The two cylinder walls 22 and 22 'have the same radius of curvature 27 on their outer side 26 and their centers of curvature 28 lie in the pivot axes 16 and 17. The other two cylinder walls 23 and 23' have a likewise corresponding radius of curvature 30 on their inner sides 29 and their centers of curvature 31 in turn lie in the pivot axes 16 and 17. The radius of curvature 27 is larger than the radius of curvature 30.

Den beiden Paaren von Zylinderwandungen 22, 22' und 23, 23' stehen Stege 32, 32' und 33, 33' (bzw.deren Enden)in geringem Abstand gegenüber, die entlang den Längsseiten 14 der Torflügel 1, 2, 3 angeordnet sind. Diese Stege 32, 32'-, 33, 33' sind die U-Schenkel eines stranggepreßten U-Profiles 34 aus Aluminium, welches beide Längsseiten 14 jedes Torflügels 1, 2, 3 bildet und an denen die Aussenwand 10 und die Innenwand 11 befestigt sind. Die Stege 32, 32', 33 und 33' setzen demgemäß an der Außenwand 10 bzw. der Innenwand 11 der Torflügel 1, 2, 3 an und sie liegen im wesentlichen in den Ebenen von Außenwand 10 und Innenwand 11. Wird der Krümmungsradius 30 wesentlch kleiner als der Krümmungsradius 27 gewählt und zugleich der Stoß 25 durch ein Verbindungsstück (nicht dargestellt) verbreitert, dann gelingt es ohne weiteres, daß der Abstand zwischen den Stegen 32 und 32' sowie den Stegen 33 und 33' gleichgroß gemacht werden kann, was bedeutet, daß Vorderseite und Rückseite des geschlossenen Schiebefalttores identisches Aussehen aufweisen.The two pairs of cylinder walls 22, 22 'and 23, 23' are spaced apart by webs 32, 32 'and 33, 33' (or their ends), which are arranged along the longitudinal sides 14 of the gate leaves 1, 2, 3 . These webs 32, 32'-, 33, 33 'are the U-legs of an extruded U-profile 34 made of aluminum, which forms both longitudinal sides 14 of each gate leaf 1, 2, 3 and to which the outer wall 10 and the inner wall 11 are fastened . The webs 32, 32 ', 33 and 33' accordingly apply to the outer wall 10 or the inner wall 11 of the gate leaves 1, 2, 3 and they lie essentially in the planes of the outer wall 10 and the inner wall 11. If the radius of curvature 30 becomes essential chosen smaller than the radius of curvature 27 and at the same time the joint 25 widened by a connecting piece (not shown), then it is readily possible that the distance between the webs 32 and 32 'and the webs 33 and 33' can be made the same size, which means that the front and back of the closed sliding folding door have an identical appearance.

Die Zylinderwandungen 22, 22' und 23, 23' sind durch Querstege 35 miteinander verbunden, wodurch sich zwischen den Zylinderwandungen 22, 22' und 23, 23' ein Hohlraum 36 ergibt, in welchem Dämmaterial 37 vorgesehen ist.The cylinder walls 22, 22 'and 23, 23' are connected to one another by transverse webs 35, which results in a cavity 36 between the cylinder walls 22, 22 'and 23, 23', in which insulating material 37 is provided.

Längs der freien Enden der Stege 32, 32', 33 und 33' sind Dichtungsbänder 38 angeordnet. Dabei handelt es sich um langgestreckte, schmale Bürsten, die in Nuten (nicht dargestellt) eingeschoben oder eingeklemmt sind.Sealing tapes 38 are arranged along the free ends of the webs 32, 32 ', 33 and 33'. These are elongated, narrow brushes which are inserted or clamped in grooves (not shown).

An den Innenwänden 10 der Torflügel 1, 2, 3 sind Dichtungspolster 39 befestigt, die sich entlang der ganzen Längsseite 14 der Torflügel 1, 2, 3 erstrecken. Die Zylinderwandungen 22, 23' weisen ein kurzes, verlängertes Ende 40 auf, mit welchen sie in Geschlossenstellung der Torflügel 1, 2, 3 an die Dichtungspolster 39 anstoßen und dichtend anliegen.Sealing pads 39 are attached to the inner walls 10 of the door leaves 1, 2, 3 and extend along the entire longitudinal side 14 of the door leaves 1, 2, 3. The cylinder walls 22, 23 'have a short, elongated end 40, with which they abut the sealing pads 39 in the closed position of the gate leaves 1, 2 and rest sealingly.

Die zur schwenkbaren Verbindung der Verbindungsschienen 15 mit den Torflügeln .1, 2 bzw. 3 dienenden Scharniere 19 sind mit ihrer einen Scharnierplatte 41 am Quersteg 35 (bzw. an dessen über die Zylinderwandung 22 hinausstehenden Verlängerung), und mit ihrer anderen, den Gelenkstift 42 ebenfalls umgreifenden Scharnierplatte 43 am einen U-Schenkel des U-Profiles 34 bzw. am Steg 33 angeschraubt. In einer anderen Ausführungsform dieses Gelenkes (die in Figur 3 im Bereich der Zylinderwandung 23' und des Steges 33' erkennbar ist) ist anstelle der Scharniere an der Verbindungsschiene 15 in Verlängerung des Quersteges 35 ein Band 44 angeformt, welches einen endständigen, ebenfalls angeformten Gelenkbolzen 45 trägt. Dieser Gelenkbolzen 45 sitzt drehbar in einer Gelenkhülse 46, die an der Außenwand (10) des Torflügels 1, 2, 3 (bzw. am Steg 33') angeformt ist und einen Längsschlitz 47 trägt, der einen Zentriwinkel von wenigstens neunzig Grad aufweist. Der Gelenkbolzen 45 ist an mehreren über die Längsseite 14 verteilten Stellen mit einer geschlitzten Lagerschale 48 aus Kunststoff umgeben, wodurch sich eine Schmierung dieses Gelenkes erübrigt.The hinges 19 used for the pivotable connection of the connecting rails 15 to the gate leaves .1, 2 or 3 are with their one hinge plate 41 on the transverse web 35 (or on its extension projecting beyond the cylinder wall 22), and with their other, the articulated pin 42 also surrounding hinge plate 43 screwed to a U-leg of the U-profile 34 or to the web 33. In another embodiment of this joint (which can be seen in FIG. 3 in the area of the cylinder wall 23 'and the web 33'), instead of the hinges on the Connecting rail 15 in the extension of the cross bar 35, a band 44 is formed, which carries a terminal, also molded hinge pin 45. This hinge pin 45 is rotatably seated in a hinge sleeve 46, which is formed on the outer wall (10) of the gate leaf 1, 2, 3 (or on the web 33 ') and carries a longitudinal slot 47 which has a central angle of at least ninety degrees. The hinge pin 45 is surrounded at several locations distributed over the long side 14 with a slotted bearing shell 48 made of plastic, which makes lubrication of this hinge unnecessary.
