Abstract

Door leaf made of a number of panels connected by means of hinges, in particular an articulated ceiling door, in which the insertion of fingers into the gap between two consecutive panels is prevented in that those end faces of adjacent panels which are turned towards one another are provided with end surfaces which run in arched manner approximately about the hinge axis, so that a finger-wide gap does not arise between the panels in any pivoting position, in which connection, outside the end surfaces which run in an arched manner and start from the outside of the door leaf, in the region close to the inside of the door leaf, step regions are formed, which engage in one another in the closed position of the door leaf. In order to be able simply to manufacture such a door made of panels in a tight or supported or accurately oriented closed position in relation to one another, a gap section, in which the gap distance is interrupted and across which the panels, in the closed position of the door leaf, lie against one another, is provided in the gap region between those end faces of adjacent panels which are turned towards one another, seen from the outside of the door leaf to the inside of the door leaf.

Description

Die Erfindung bezieht sich auf ein Torblatt mit den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a door leaf with the features of the preamble of claim 1.

Ein solches Torblatt ist aus der DE 37 26 699 A1 bekannt. Beim Übergang von der Schließlage in die Öffnungslage und umgekehrt durchlaufen die in Bewegungsrichtung aufeinanderfolgend aneinander angelenkten Paneele eines solchen Torblattes - insbesondere eines Sektionaltores - einen bogenförmigen Führungsbereich, der sich zwischen dem etwa vertikal gerichteten geradlinigen Führungsabschnitt für die Aufnahme des Torblattes in der Schließstellung und dem etwa horizontal verlaufenden Führungsabschnitt für die Aufnahme des Torblattes in der Offenstellung befindet. Zu diesem Zwecke sind die Paneele durch Scharniere aneinander angelenkt, deren Scharnierachse an der Torblattinnenseite verläuft, der Torblattseite also, die dem Inneren des mit dem Torblatt zu verschließenden Gebäuderaumes oder dergleichen zugewandt ist. Um zu verhindern, daß in den bei Durchlaufen des bogenförmigen Führungsbereiches entstehenden Verschwenklagen benachbarter Paneele zueinander zwischen diesen ein Spalt entsteht, in welchen man mit den Fingern ungewollt oder im Zuge einer insoweit nicht sachgerechten Handhabung des Torblattes von Hand eingreifen kann, sind die einander zugewandten Stirnseiten der jeweils benachbarten Paneele mehr oder weniger im Querschnitt kreisbogenförmig verwölbt ausgebildet, und zwar in etwa mit dem Kreisbogenmittelpunkt in der Scharnierachse gelegen. Dabei ist zwischen den beiden einander gegenüberliegenden verwölbten Stirnseiten jeweils ein Spalt gebildet, der sich zwischen der Außenseite und der Innenseite des Torblattes durchgehend erstreckt, wenn man von gesondert vorgesehenen, elastischen Dichtungsstreifen absieht. Die Verbindung zwischen den jeweils benachbarten Paneelen unter Einhaltung des dort vorgesehenen Spaltes wird durch die zugehörigen Scharnierverbindungen sichergestellt und muß nicht zuletzt wegen der vorgesehenen Dichtungen in genauer Zuordnung erfolgen, was bei Anbringung dieser Scharnierverbindungen zwischen den Paneelen entsprechend umständlich ist.Such a door leaf is known from DE 37 26 699 A1. During the transition from the closed position to the open position and vice versa, the panels of such a door leaf, in particular a sectional door, which are articulated in succession in the direction of movement pass through an arcuate guide region which is located between the approximately vertically directed rectilinear guide section for receiving the door leaf in the closed position and approximately horizontally extending guide section for receiving the door leaf is in the open position. For this purpose, the panels are articulated to one another by hinges, the hinge axis of which runs on the inside of the door leaf, ie the side of the door leaf which faces the interior of the building space or the like to be closed with the door leaf. In order to prevent a gap from forming between the adjacent panels in the pivoting positions of adjacent panels when they pass through the arcuate guide area, in which one can intervene with the fingers unintentionally or in the course of improper handling of the door leaf, the mutually facing end faces are each of the adjacent panels is more or less arched in cross-section, and is located approximately at the center of the circular arc in the hinge axis. In this case, a gap is formed between the two opposite, arched end faces, which extends continuously between the outside and the inside of the door leaf, with the exception of separately provided, elastic sealing strips. The connection between the adjacent panels, while observing the gap provided there, is ensured by the associated hinge connections and, not least because of the seals provided, must be made in an exact assignment, which is correspondingly cumbersome when these hinge connections are made between the panels.

Andererseits ist bei diesem Stand der Technik im Gegensatz zu anderen bekannten Ausbildungen - FR-PS 1.310.605, DE-GM 88 00 956 - eine Stufenausbildung vorgesehen, bei welcher an die konvex und konkav ausgebildeten Oberflächenbereiche anschließend Stufenbereiche vorgesehen sind, die in der Torblattschließstellung ineinandergreifen. Aufgrund dieses Stufenverlaufes wird der Spalt nach Art einer Labyrinthdichtung geführt, die Stufenbereiche können eine Versetzbewegung der Paneele senkrecht zur Ebene des geschlossenen Torblattes behindern, beispielsweise unter Windeinfluß, und die Scharnierlappen finden an den Stufenbereichen eine geeignete Anlagefläche und lassen sich besser proportionieren.On the other hand, in this prior art, in contrast to other known designs - FR-PS 1.310.605, DE-GM 88 00 956 - a step design is provided in which step areas are provided on the convex and concave surface areas, which are in the door leaf closed position interlock. Because of this step profile, the gap is guided like a labyrinth seal, the step areas can hinder a movement of the panels perpendicular to the level of the closed door leaf, for example under the influence of wind, and the hinge lugs find a suitable contact surface on the step areas and can be proportioned better.

Der Erfindung liegt die Aufgabe zugrunde, ein Torblatt der eingangs genannten Art zur Verfügung zu stellen, dessen benachbarte Paneele unter verbesserten Dichtungsbedingungen exakt und einfach verbindbar sind.The invention has for its object to provide a door leaf of the type mentioned, the adjacent panels can be connected precisely and easily under improved sealing conditions.

Ausgehend von einem Torblatt mit den Merkmalen des Oberbegriffes des Anspruches 1 wird diese Aufgabe erfindungsgemäß durch dessen kennzeichnende Merkmale gelöst.Starting from a door leaf with the features of the preamble of claim 1, this object is achieved according to the invention by its characterizing features.

Erfindungsgemäß sind die einander zugewandten Stirnseiten je zweier benachbarter Paneele derart gestaltet, daß der zwischen Ihnen gebildete Spalt bei etwa in einer Ebene verlaufendem Torblatt, also im deckennahen Öffnungszustand, oder - was hier wichtig ist - im Schließzustand des Torblattes derart unterbrochen ist, daß die beiden Stirnseiten in einem Teilbereich des sich von der Außenseite des Torblattes zu dessen Innenseite hin erstreckenden Spaltes in einem Spaltabschnitt aneinander anliegen und sich das obere Paneel an dem jeweils unteren Paneel abstützt. Damit kann man in diesem Spaltabschnitt bzw. Anlagebereich nicht nur eine Abdichtung zwischen den Paneelen herbeiführen, sondern vor allem die Lage der Paneele im Torblattschließzustand zueinander exakt bestimmen, so daß eine im übrigen Spaltbereich vorgesehene Dichtung wegen der dort definierten Spaltbreite und dergleichen Formgebung genau bemessen und hinsichtlicher ihrer Elastizität derart bestimmt werden kann, daß eine Dichtung unter minimalem Verschleiß und geringstem Reibwiderstand vorgesehen werden kann. Von besonderem Vorteil ist, daß jeweils benachbarte Paneele durch den Angriff im Anlagebereich des Spaltabschnittes aneinander genau Abstandsdefiniert angeordnet werden können, bevor die Gelenkverbindung zwischen den Paneelen durch die Scharnierverbindung, insbesondere in Form von über die quer zur Bewegungsrichtung verlaufende Länge verteilt angeordneten Scharnieren, hergestellt wird, deren lagegerechte Anbringung sich dadurch ganz erheblich erleichtert. Darüber hinaus können die Paneele im Schließzustand des Torblattes aufeinander abgestützt ruhen, praktisch ohne die Scharnierverbindungen zwischen ihnen zu belasten, so daß diese insoweit nur auf Zug beansprucht werden und Wechselbelastungen entfallen, die die Dauerhaftigkeit der Scharnierbefestigungen beeinträchtigen können.According to the invention, the mutually facing end faces of two adjacent panels are designed in such a way that the gap formed between them is interrupted in such a way that the door leaf runs approximately in one plane, i.e. in the opening state close to the ceiling, or - which is important here - in the closed state of the door leaf in such a way that the two End faces in a partial area of the gap extending from the outside of the door leaf to the inside thereof abut against one another in a gap section and the upper panel is supported on the respective lower panel. This means that not only can a seal be created between the panels in this gap section or contact area, but above all the position of the panels in the door leaf closing state can be precisely determined with respect to one another, so that a seal provided in the remaining gap area is dimensioned precisely because of the gap width and the like shape defined there and with regard to their elasticity can be determined in such a way that a seal can be provided with minimal wear and the lowest frictional resistance. It is of particular advantage that adjacent panels can be arranged at precisely defined distances from one another by the attack in the contact area of the gap section before the articulated connection between the panels is produced by the hinge connection, in particular in the form of hinges arranged distributed over the length running in the direction of movement , their correct fitting is considerably easier. In addition, the panels can rest against each other in the closed state of the door leaf, practically without stressing the hinge connections between them, so that they are only stressed to the extent that alternating loads are eliminated, which can impair the durability of the hinge fastenings.

Die schematisierte Seitenansicht eines Sektionaltores nach Figur 1 zeigt ein insgesamt mit 1 bezeichnetes Torblatt, das in der Schließstellung 2 mit durchgezogenen Linien wiedergegeben ist, während die gestrichelte Wiedergabe des Torblattes bzw. der Paneele annähernd die Öffnungsstellung 3 des Torblattes unterhalb der Decke eines mit dem Torblatt zu verschließenden Raumes erkennen läßt. Das in der Schließstellung unterste Paneel ist mit 4', das darüber angeordnete mit 4 und das widerum oberhalb des Paneels 4 gelegene Paneel mit 4" bezeichnet. Im Scharnierbereich zwischen den Paneelen sind an diesen Rollen 5 vorgesehen, die in Führungsschienen 6 eingreifen, wie dies bei den Toren dieser Art allgemein bekannt ist. Die Führungsschienen setzen sich aus einem etwa vertikal verlaufenden, geradlinigen Abschnitt für die Aufnahme des Torblattes in der Schließstellung 2, einem bogenförmigen Übergangsabschnitt und einem etwa horizontal geradlinig verlaufenden Abschnitt für die Aufnahme des Torblattes in der Öffnungsstellung zusammen. Für die obere Rolle des in der Schließstellung obersten Paneeles ist eine gesonderte horizontale Führung mit schräg verlaufendem Übergangsstück 6' vorgesehen, um das oberste Paneel bei geringer Sturzhöhe in die Schließlage zu überführen, wie dies Figur 1 erkennen läßt. In der Schließlage 2 bildet das Torblatt eine nach außen gerichtete Torblattaußenseite 17 und eine in das Innere des zu verschließenden Raumes gerichtete Torblattinnenseite 18.The schematic side view of a sectional door according to FIG. 1 shows a door leaf designated as a whole by 1, which is shown in the closed position 2 with solid lines, while the dashed representation of the door leaf or the panels approximately the open position 3 of the door leaf below the ceiling of one with the door leaf reveals the room to be locked. The lowest panel in the closed position is denoted by 4 ', the one arranged above it by 4 and the panel located above the panel 4 by 4 ".

In den Figuren 2 bis 9 ist jeweils der Verbindungsbereich zwischen zwei benachbarten Paneelen 4 und 4' wiedergegeben, und zwar zeigt die jeweils linke Darstellung die beiden Paneele in der Verschwenkstellung, in der sie sich in einer Torblattebene befinden, hier in der Torblattschließstellung 2, und die jeweils rechte Darstellung zeigt die Paneele in der Verschwenkstellung, in der sie beim Übergang zwischen der Torblattschließstellung 2 und der Torblattöffnungsstellung 3 ihren größten Verschwenkwinkel 16 zueinander einnehmen. In der Torblattschließstellung liegt die nach oben gerichtete Stirnseite 8 des jeweils unteren Paneels 4' der nach unten gerichteten Stirnseite 9 des oberen Paneels 4 gegenüber. Die nach oben gerichtete Stirnseite 8 weist einen konvexen Oberflächenbereich 10 und die nach unten gerichtete Stirnseite 9 einen konkaven Oberflächenbereich 11 auf, welche Bereiche bogenförmig, insbesondere kreisbogenförmig etwa mit dem Mittelpunkt in der Scharnierachse 13 gelegen ausgebildet sein können. Im Rahmen der vorliegend wiedergegebenen Ausführungsbeispiele sind sowohl der konvexe Oberflächenbereich 10 als auch der konkave Oberflächenbereich 11 jeweils in Gestalt eines Polygons aus mehreren Polygonabschnitten ausgebildet. Die Brennpunkte der Polygonzüge aus den jeweiligen Polygonabschnitten, d.h. die Schnittpunkte der Mittelsenkrechten auf den einzelnen Abschnitten, treffen sich in einem Punkt oder Punktbereich, der in der Scharnierachse 13 oder nahe bei dieser, zumindest aber auf die benachbarte Scharnierachse 13 zu gerichtet liegt. Zwischen den aus diesen Polygonabschnitten 48 und 49 bzw. 50, 51 und 52 gebildeten konvexen und konkaven Oberflächenbereichen 11 bzw. 11 der beiden in der Torblattschließstellung - jeweils linke Darstellung - einander gegenüberliegenden Stirnseiten 8 und 9 wird ein Spaltbereich 15 gebildet, der in den wiedergegebenen Ausführungsbeispielen über die Dicke der Paneele gesehen nicht gleichbleibend breit verlaufend ausgebildet ist. Es kann der Oberflächenbereich 10 der nach unten weisenden Stirnseite 9 des oberen Paneels 4 auch rechtwinkelförmig ausgebildet sein, wobei der nach unten abragende Schenkel in der Außenfläche des Torblattes verläuft und mit seiner frei abragenden Kante unter Nachzeichnung des Spaltbereiches gegenüber dem nach oben konvex verwölbten Oberflächenbereich 10 des unteren Paneels 4' im Zuge der Verschwenkbewegung der Paneele gegeneinander verschoben wird. Wichtig ist dabei, daß der Spaltbereich 15 in jedem durch den Betrieb bedingten Verschwenkzustand zwischen den Paneelen 4 und 4' so schmal bleibt, daß ein Fingereingriff nicht möglich ist. Dies gilt für alle angesprochenen und vergleichbaren Ausbildungen der konvexen und konkaven Oberflächenbereiche. Jeweils läuft der Oberflächenbereich 11 der nach unten gerichteten Stirnseite 9 in einer Nasenkante 23 aus, während der konvexe Oberflächenbereich 10 der nach oben gerichteten Stirnseite 8 von der Torblattaußenseite 17 her gesehen ins Paneelinnere hinein in einer Eckkante 22 ausläuft. Wie die jeweils rechte Darstellung der Figuren 2 bis 9 erkennen läßt, endet die Überlappung der Oberflächenbereiche 10 und 11 über einen Restwinkelbereich im Zuge sich vergrößernden Schwenkwinkels, so daß zwischen der Nasenkante 23 und der Eckkante 22 ein Öffnungsspalt 21 gebildet wird, der kleiner ist, als daß die Finger einer Hand durch diesen Öffnungsspalt in den Raum zwischen den Stirnseiten 8 und 9 der Paneele 4 und 4' eingeführt werden könnten; diese Weite des Öffnungsspaltes 21 ist vorzugsweise kleiner als 4 mm.In Figures 2 to 9, the connection area between two adjacent panels 4 and 4 'is shown, and that the left illustration shows the two panels in the pivoted position, in which they are in a door leaf level, here in the door leaf closed position 2, and the right-hand illustration shows the panels in the pivoting position, in which they assume their greatest pivoting angle 16 relative to one another during the transition between the door leaf closing position 2 and the door leaf opening position 3. In the door leaf closed position, the upward end face 8 of the respective lower panel 4 'is opposite the downward end face 9 of the upper panel 4. The upward-facing end face 8 has a convex surface area 10 and the downward-facing end face 9 has a concave surface area 11, which areas can be designed in an arcuate, in particular circular arc shape, approximately with the center in the hinge axis 13. Within the scope of the exemplary embodiments shown here, both the convex surface area 10 and the concave surface area 11 are each formed in the form of a polygon from a plurality of polygon sections. The focal points of the polygons from the respective polygon sections, that is to say the intersection points of the perpendicular bisectors on the individual sections, meet at a point or point region which is located in the hinge axis 13 or close to it, or at least towards the adjacent hinge axis 13. A gap region 15 is formed between the convex and concave surface regions 11 and 11 of the two front sides 8 and 9, which are formed from these polygon sections 48 and 49 and 50, 51 and 52, respectively, in the door leaf closed position - shown on the left - and shown in FIGS Embodiments seen across the thickness of the panels do not run consistently wide is trained. The surface area 10 of the downward-facing end face 9 of the upper panel 4 can also have a rectangular shape, the downwardly projecting leg running in the outer surface of the door leaf and with its freely projecting edge, tracing the gap area with respect to the upwardly convex surface area 10 of the lower panel 4 'in the course of the pivoting movement of the panels against each other. It is important that the gap area 15 remains so narrow in any pivoting state between the panels 4 and 4 'caused by the operation that finger intervention is not possible. This applies to all mentioned and comparable designs of the convex and concave surface areas. In each case, the surface area 11 of the downward face 9 ends in a nose edge 23, while the convex surface area 10 of the upward face 8, seen from the outside of the door leaf 17, runs out into the inside of the panel in a corner edge 22. As can be seen from the right-hand illustration of FIGS. 2 to 9, the overlap of the surface areas 10 and 11 ends over a residual angle area in the course of an increasing swivel angle, so that an opening gap 21 which is smaller is formed between the nose edge 23 and the corner edge 22. than that the fingers of one hand could be inserted through this opening gap into the space between the end faces 8 and 9 of the panels 4 and 4 '; this width of the opening gap 21 is preferably less than 4 mm.

Im Spaltbereich der Torblattaußenseite 17, d.h. in den Figuren 2 bis 9 nach links gerichtet, ist zwischen den Außenwandungen der Paneele 4 und 4' eine Fuge freigelassen, die in den Spaltbereich 15 übergeht. Diese Fuge simmuliert eine Sicke, deren mehrere in nicht dargestellter Weise im Bereich der Paneele vorgesehen sind.In the gap area of the outside of the door leaf 17, i.e. In Figures 2 to 9 directed to the left, a joint is left between the outer walls of the panels 4 and 4 ', which merges into the gap area 15. This joint simulates a bead, several of which are provided in a manner not shown in the area of the panels.

Während der zwischen den Oberflächenbereichen 10 und 11 der Stirnseiten 8 und 9 in der Torblattschließstellung 2 gebildete Spaltbereich 15 sich - abgesehen von einer Dichtung 33 - zur Torblattaußenseite 17 hin öffnet, setzt sich der Spalt - besser die Trennebene - zwischen den Stirnseiten 8 und 9 in Richtung der Torblattinnenseite 18 gesehen in einem Stufenabschnitt fort, der zwischen einem von der nach oben gerichteten Stirnseite 8 nach unten und damit ihn das zugeordnete Paneel 4' hinein gerichteten Stufenbereich 19 und einem von der nach unten gerichteten Stirnseite 9 nach unten und damit von dem zugeordneten Paneel 4 abragend ausgebildeten Stufenbereich 20 gebildet ist. Die in der Torblattschließstellung ineinandergreifenden Stufenbereiche 19 und 20 bilden zusammen mit den konvexen und den konkaven Oberflächenbereichen 10 und 11 einen formschlüssigen Eingriff zwischen den einander zugewandten Stirnseiten 8 und 9 benachbarter Paneele, so daß diese sich unter senkrecht zu ihrer Torblattbreitseite gerichteten Kräften - beispielsweise Winddruck - nicht gegeneinander verschieben können und damit keine Öffnungsbildung in dem in der Schließstellung befindlichen Torblatt zulassen. Sie dienen darüber hinaus der Aufnahme der Scharnierlappen 26 und 27 der Scharniere 12, deren Scharnierachsbereich in besonders bevorzugter Ausführung zwischen die in der Torblattschließstellung aufeinander zu gerichteten Stirnseitenbereiche 63 und 64 der Stufenbereiche 19 bzw. 20 mehr oder weniger weit eingreifend aufgenommen ist.While the gap area 15 formed between the surface areas 10 and 11 of the end faces 8 and 9 in the door leaf closing position 2 opens - apart from a seal 33 - towards the outside of the door leaf 17, the gap - better the parting plane - settles between the end faces 8 and 9 in Seen in the direction of the door leaf inner side 18 in a step section, which extends between a step region 19 directed downwards from the upward end face 8 and thus the associated panel 4 ′ and a step region 19 directed downward from the downward end face 9 and thus from the associated one Panel 4 projecting step area 20 is formed. The interlocking step regions 19 and 20 in the door leaf closed position, together with the convex and concave surface regions 10 and 11, form a positive engagement between the mutually facing end faces 8 and 9 of adjacent panels, so that these are subjected to forces directed perpendicularly to their broad side of the door leaf - for example wind pressure - cannot move against each other and therefore do not allow opening in the door leaf in the closed position. They also serve to accommodate the hinge tabs 26 and 27 of the hinges 12, the hinge axis area of which, in a particularly preferred embodiment, is more or less engagingly received between the end face areas 63 and 64 of the step areas 19 and 20 which are directed towards one another in the door leaf closed position.

Der nach unten abragende Stufenbereich 20 an der nach unten gerichteten Stirnseite 9 läuft zusammen mit der an der Mündung des Spaltbereiches 15 in der Torblattaußenfläche gelegenen Nasenkante 23 jeweils desselben Paneels 4 in einer Ebene aus, die senkrecht zu den Paneelbreitseiten verläuft und ein sicheres Abstellen des Paneels 4 hochkant auf einem ebenen Boden erlaubt.The downwardly protruding step region 20 on the downward end face 9 runs together with the nose edge 23 located at the mouth of the gap region 15 in the outer surface of the door leaf of the same panel 4 in a plane that runs perpendicular to the broad sides of the panel and a secure parking of the panel 4 upright allowed on a flat floor.

Die in den Figuren 2 bis 9 wie auch in den übrigen Figuren wiedergegebenen, in Scharnierachsrichtung gesehenen Querschnittskonturen der Paneele gehören jeweils zu Wandungsausbildungen, die sich über die gesamte Länge der Paneele, d.h. die gesamte Torblattbreite senkrecht zur Bewegungsrichtung des Torblattes, in dieser Konturenform gleichmäßig erstrecken.The cross-sectional contours of the panels shown in FIGS. 2 to 9, as well as in the other figures, seen in the hinge axis direction, each belong to wall configurations that extend over the entire length of the panels, i.e. extend the entire door leaf width perpendicular to the direction of movement of the door leaf in this contour shape.

Die vorgeschilderten Merkmale sind den gezeichneten Ausführungsformen gemeinsam und zum Teil aus dem eingangs genannten Stand der Technik bekannt. Die nachfolgende Beschreibung der einzelnen Ausführungsbeispiele berücksichtigt deren unterschiedlichen Einzelaufbau sowie unterschiedliche Scharnierausbildungen und -anordnungen und vor allem die Ausbildung des Spaltabschnittes 60, in welchem die jeweils benachbarten Paneele in der Torblattschließstellung aneinanderliegen bzw. aufeinander abgestütz sind. Insbesondere letzteres hat den großen Vorteil, daß im Zuge des Torblattaufbaues die jeweils aufeinander aufgesetzten Paneele durch die Abstützung ihre optimale Zuordnung erfahren, woraufhin sich die Scharniere besonders einfach in der richtigen Lage anbringen lassen und damit die Beibehaltung der optimalen Ausrichtung und Zuordnung der Paneele zueinander im fertigen Torblatt sicherstellen. Soweit sich bestimmte Ausbildungen und Merkmalsgruppen bei den unterschiedlichen Ausführungsformen aus der jeweiligen Zeichnung entnehmbar wiederholen, wird darauf im Folgenden nicht näher eingegangen.The features described are common to the illustrated embodiments and in part are known from the prior art mentioned at the outset. The following description of the individual exemplary embodiments takes into account their different individual construction, different hinge designs and arrangements and, above all, the design of the gap section 60, in which the respectively adjacent panels lie against one another or are supported on one another in the door leaf closed position. The latter in particular has the great advantage that, in the course of building the door leaf, the panels placed one on top of the other are optimally assigned by the support, whereupon the hinges can be attached particularly easily in the correct position and thus maintaining the optimal alignment and assignment of the panels to one another ensure the finished door leaf. Insofar as certain designs and groups of features repeat themselves in the different embodiments from the respective drawing, this will not be discussed in more detail below.

Figur 2 zeigt eine erste Ausführungsform der Paneele 4, und zwar in Form einer einzigen Schale 29, deren zur Torblattaußenseite 17 hin gerichtete Breitseite als Außenwandung 35 des Paneels ausgebildet ist. Von der Torblattinnenseite 18 her gesehen sind die Paneele "offen" und zwar bis auf quer zur Bewegungsrichtung verlaufende obere und untere Randbereiche 24, 25, die jeweils auf sich selbst zurückgefaltet sind und somit eine verstärkte Zone für die Festlegung der Scharnierlappen 26 und 27 der Scharnierverbindung 12 mit Hilfe von Schrauben 36 bilden. Die Scharnierverbindung 12 besteht aus mehreren, über die Breite der Paneele in Richtung der Scharnierachse 13 aufeinanderfolgend angeordneten Einzelscharnieren. Die aus dünnem Blech bestehende Schale 29 ist mittels Streben 39 ausgesteift, die im Bereich der Scharnierlappen 26 und 27 mit zungenförmigen Enden 40 außenseitig auf den Randbereichen 24 aufliegen. Diese zungenförmigen Enden 40 werden mit von den Schrauben 36 durchgriffen.FIG. 2 shows a first embodiment of the panels 4, specifically in the form of a single shell 29, the broad side of which is directed toward the outside of the door leaf 17 and is designed as the outer wall 35 of the panel. From the inside of the door leaf 18 ge see the panels are "open", namely up to transverse to the direction of movement upper and lower edge regions 24, 25, which are each folded back on themselves and thus a reinforced zone for the fixing of the hinge tabs 26 and 27 of the hinge connection 12 with the aid of screws 36 form. The hinge connection 12 consists of a plurality of individual hinges arranged one after the other across the width of the panels in the direction of the hinge axis 13. The shell 29 made of thin sheet metal is braced by means of struts 39 which rest on the outside on the edge regions 24 with tongue-shaped ends 40 in the area of the hinge tabs 26 and 27. These tongue-shaped ends 40 are penetrated by the screws 36.

Die in der Torblattschließstellung einander zugewandten Stirnseiten 8 (unteres Paneel 4') und 9 (oberes Paneel 4) setzen sich aus verschiedenen Abschnitten zusammen. Die nach oben weisende Stirnfläche 8 wird von der Torblattaußenseite 17 her gesehen nach einer der Nasenkante 23 des oberen Paneels 4 gegenüberliegenden, eine Sicke nachbildenden Abkantung durch einen konvexen Oberflächenbereich 10 aus einem Polygonzug von Abschnitten 50, 51 und 52 gebildet, auf den in Richtung auf die Torblattinnenseite 18 zu ein Stirnseitenbereich 61 folgt, der weiter in dieser Richtung nach innen gesehen in eine etwa parallel zur Torblattinnenfläche verlaufende Wandung übergeht, an die sich eine schräg zur Torblattinnenseite 18 verlaufende Wandung 63 anschließt. Die beiden zuletzt erwähnten Wandungen bilden den Stufenbereich 19 der Stirnseite 8, der sich zum Inneren des zugehörigen Paneels hin erstreckt. Die nach unten gerichtete Stirnseite 9 wird von der Torblattaußenseite 17 aus gesehen durch einen an die Nasenkante 23 anschließenden, den konkaven Oberflächenbereich 11 bildenden Polygonzug aus den Abschnitten 48 und 49 gebildet, auf den in Richtung auf die Torblattinnenseite 18 zu ein Stirnseitenbereich 62 folgt, der weiter in dieser Richtung nach innen gesehen in einer etwa parallel zur Torblattinnenfläche verlaufende Wandung übergeht, an die sich eine schräg zur Torblattinnenseite 18 verlaufende Wandung 64 anschließt. Diese beiden zuletzt erwähnten Wandungen bilden zusammen mit einem Bereich der zur Torblattinnenseite 18 weisenden Paneelwandung den Stufenbereich 20 der Stirnseite 9, der sich vom Inneren des zugehörigen Paneels abgewandt erstreckt und in der in der linken Darstellung wiedergegebenen Torblattschließstellung in den insoweit eine Ausnehmung bildenden Stufenbereich 19 des benachbarten Paneels eingreift.The end faces 8 (lower panel 4 ') and 9 (upper panel 4) facing each other in the door leaf closed position are composed of different sections. The upward-facing end face 8 is seen from the outer side 17 of the door leaf after an edge opposite the nose edge 23 of the upper panel 4, which simulates a bead, is formed by a convex surface area 10 made of a polygonal line of sections 50, 51 and 52, in the direction of the inside of the door leaf 18 follows an end region 61 which, seen further in this direction, merges into a wall running approximately parallel to the inside surface of the door leaf, which is followed by a wall 63 which runs obliquely to the inside of the door leaf 18. The two last-mentioned walls form the step region 19 of the end face 8, which extends towards the interior of the associated panel. The downward facing end face 9 is formed from the door leaf outer side 17 as seen by a polygonal line from sections 48 and 49, which adjoins the nose edge 23 and forms the concave surface area 11, followed by an end face region 62 in the direction of the door leaf inner side 18, which seen further inward in this direction, it merges into a wall running approximately parallel to the inner surface of the door leaf, which is followed by a wall 64 running obliquely to the inner side of the door leaf 18. These two last-mentioned walls, together with an area of the panel wall facing the inside of the door leaf 18, form the step area 20 of the end face 9, which extends away from the interior of the associated panel and, in the door leaf closed position shown in the left-hand illustration, in the step area 19 forming a recess engages adjacent panels.

Die beiden Oberflächenbereiche 10 und 11 der Stirnseiten 8 und 9 schließen in der Torblattschließstellung den Spaltbereich 15 ein, in welchem die Stirnseiten voneinander beabstandet sind. Die beiden Stirnseitenbereiche 61 und 62 der Stirnseiten 8 und 9 liegen dagegen aneinander und bilden den Spaltabschnitt 60, in welchem der Spaltabstand des Spaltverlaufes von der Torblattaußenseite 17 zu der Torblattinnenseite 18 hin entsprechend unterbrochen ist. Der Spaltabschnitt 60 bildet insoweit einen Abstützbereich mit Abstütz- oder Anlageflächen 61 und 62. Weiter zur Torblattinnenseite 18 gesehen entsteht wieder ein Spaltabstand zwischen den etwa parallel zueinander und zur Torblattinnenwandung verlaufenden Wandungen der beiden Stufenbereiche 19 und 20 und mündet zwischen deren Wandungen 63 und 64, die zur Torblattinnenseite 18 hin gesehen die Seitenwandungen eines sich öffnenden Trapezes bilden. Das Querschnittsbild benachbarter Paneele in der Torblattschließstellung zeigt also keinen von der Torblattaußenseite 17 zu der Torblattseite 18 durchgehend mit Abstand versehenen Spalt auf, sondern zeigt einen Spaltverlauf, der im Spaltabschnitt 60 unterbrochen ist, weshalb besser von einer Trennlinie zwischen den Stirnseiten 8 und 9 gesprochen wird, die in der Zeichnung den Querschnittsverlauf wiedergibt und die in Breitenrichtung der Paneele gesehen die Kontur eines entsprechenden Flächenverlaufes andeutet.In the door leaf closed position, the two surface regions 10 and 11 of the end faces 8 and 9 enclose the gap region 15 in which the end faces are spaced apart from one another. The two end face regions 61 and 62 of the end faces 8 and 9, however, lie against each other and form the gap section 60, in which the gap distance of the gap course from the door leaf outer side 17 to the door leaf inner side 18 is interrupted accordingly. In this respect, the gap section 60 forms a support area with support or contact surfaces 61 and 62. Further to the inside of the door leaf 18, there is again a gap distance between the walls of the two step regions 19 and 20, which run approximately parallel to one another and to the inside wall of the door leaf, and opens between the walls 63 and 64 thereof, seen towards the inside of the door leaf 18 form the side walls of an opening trapezoid. The cross-sectional image of adjacent panels in the door leaf closed position therefore does not show a gap which is continuously spaced from the door leaf outer side 17 to the door leaf side 18, but rather shows a gap course which is interrupted in the gap section 60, which is why it is better to speak of a dividing line between the end faces 8 and 9 , which reproduces the cross-sectional profile in the drawing and which, viewed in the width direction of the panels, indicates the contour of a corresponding surface profile.

In der Zeichnung ist die bevorzugte Formgebung des Spaltabschnittes 20 bzw. der Stirnseitenbereiche oder Anlageflächen 61 und 62 als ebene Wandungen wiedergegeben, die sich parallel zur Scharnierachse 13 und senkrecht zu der Paneelebene bzw. deren Paneelbreitseiten erstrecken. Die Stirnseitenbereiche des Spaltabschnittes können aber auch im Querschnitt bzw. in Richtung der Scharnierachse gesehen gewinkelt oder verwölbt verlaufen und/oder müssen nicht exakt senkrecht zur Paneelebene ausgerichtet sein. Hier, wie auch in den Ausführungen nach den Figuren 3 bis 7, ist der vorgeschilderte Verlauf der Stirnseitenbereiche 61 und 62 des Spaltbereiches 60 jeweils zwischen den konkaven bzw. konvexen Oberflächenbereichen und den etwa parallel zur Paneelebene verlaufenden Wandungen der Stufenbereiche 19 und 20 angeordnet, man kann auch sagen in der Endzone des Spaltbereiches, an die die Stufenbereiche anschließen. Dann spricht man den Spaltabschnitt insoweit als Teil des Spaltbereiches 15 an und kann für den in diesen Ausführungsbeispielen wiedergegebenen Anordnungsfall des Spaltabschnittes auch davon sprechen, daß dessen Stirnseitenbereiche 61 und 62 Teile der Polygonzüge der Oberflächenbereiche 10 und 11 bilden, also an den Polygonabschnitt 50 bzw. den Polygonabschnitt 48 anschließen. Der Spaltabschnitt kann grundsätzlich aber auch weiter auf die Mitte der Oberflächenbereiche 10 und 11 hin verschoben angeordnet bzw. im Zuge der dortigen Polygonabschnitte ausgebildet sein.In the drawing, the preferred shape of the gap section 20 or of the end face regions or contact surfaces 61 and 62 is shown as flat walls which extend parallel to the hinge axis 13 and perpendicular to the panel plane or the panel broad sides thereof. The end face regions of the gap section can also be angled or arched in cross-section or in the direction of the hinge axis and / or need not be aligned exactly perpendicular to the panel plane. Here, as in the embodiments according to FIGS. 3 to 7, the above-described course of the end face areas 61 and 62 of the gap area 60 is arranged between the concave or convex surface areas and the walls of the step areas 19 and 20 running approximately parallel to the panel plane can also say in the end zone of the gap area to which the step areas connect. Then the gap section is addressed as part of the gap area 15 and, for the arrangement case of the gap section shown in these exemplary embodiments, one can also speak of the fact that its end face areas 61 and 62 form parts of the polygon courses of the surface areas 10 and 11, that is to say to the polygon section 50 or connect the polygon section 48. In principle, however, the gap section can also be displaced further towards the center of the surface regions 10 and 11 or can be formed in the course of the polygon sections there det be.

Der Scharnierachsbereich des Scharnieres 12, im vorliegenden Fall die konkrete, stiftförmige Scharnierachse 13 nebst den diese umgreifenden Rollungsabschnitten 73, ist im Ausführungsbeispiel gemäß Figur 2 zwischen die Seitenwandungen 63 und 64 der Stufenbereiche 19 und 20 aufgenommen, während sich die Scharnierlappen 26 und 27 über parallel zu den Wandungen 63 und 64 erstreckende Zwischenstege 72 an die Rollungsabschnitte 73 anschließen und im übrigen an den zungenförmigen Enden 40 der Strebe 39 und damit den Randbereichen 24, 25 der Schalen 29 anliegen und sich in der jeweiligen Paneelebene der Torblattinnenseite 18 erstrecken. Auf diese Weise gelangt die Schwenkachse der Scharnierachsen 13 in eine Lage von der Torblattinnenseite 18 zum Paneelinneren hin versetzt, wie dies die Figur zeigt. Dies stellt eine besonders bevorzugte Anordnung dar, die auf die Formgebung der Stirnseiten 8 und 9 im Hinblick auf die auszuführende Verschwenkung bis auf einen maximalen Verschwenkwinkel 16 einen positiven Einfluß hat. Der senkrecht zur Paneeldicke gesehene Abstand zwischen der Scharnierverschwenkachse 13 und der in derselben Richtung gesehenen Mitte des Spaltabschnittes 60 beträgt etwa ein Viertel der gesamten Dickenabmessung der Paneele und damit des Torblattes.The hinge axis area of the hinge 12, in the present case the specific pin-shaped hinge axis 13 along with the rolling sections 73 encompassing it, is accommodated in the exemplary embodiment according to FIG. 2 between the side walls 63 and 64 of the step areas 19 and 20, while the hinge tabs 26 and 27 are parallel to the walls 63 and 64 extending intermediate webs 72 connect to the rolling sections 73 and otherwise rest on the tongue-shaped ends 40 of the strut 39 and thus the edge regions 24, 25 of the shells 29 and extend in the respective panel plane of the inside of the door leaf 18. In this way, the pivot axis of the hinge axes 13 moves into a position from the inside of the door leaf 18 to the interior of the panel, as shown in the figure. This represents a particularly preferred arrangement which has a positive influence on the shape of the end faces 8 and 9 with regard to the pivoting to be carried out up to a maximum pivoting angle 16. The distance between the hinge pivot axis 13 and the center of the gap section 60, seen in the same direction, perpendicular to the panel thickness is approximately a quarter of the total thickness dimension of the panels and thus of the door leaf.

Weiterhin ist aus Figur 2 ersichtlich, daß im Spaltbereich 15 zwischen den Oberflächenbereichen 10 und 11 in der Endzone des Überdekkungsbereiches, bei Übergang der Verschwenklage zwischen den benachbarten Paneelen von der Torblattoffenstellung in die Torblattschließstellung eine Dichtung 33 in Form einer sich senkrecht zur Bewegungsrichtung des Torblattes, also in Richtung der Breite der Paneele 4 erstreckenden Dichtungsleiste vorgesehen ist, die in eine in dem Oberflächenbereich 10 der nach oben gerichteten Stirnseite 8 ausgebildete, entsprechend verlaufende Dichtungs-Aufnahmenut 34 eingesetzt ist. Damit wird erreicht, daß die durch den Angriff der Dichtung 33 an dem anderen, gegenüberliegenden Oberflächenbereich 11 der nach unten gerichteten Stirnseite 9 des in der Schließstellung oberen Paneeles 4 bedingte Reibung nur über einen relativ kleinen Endverschwenkwinkelbereich zwischen den Paneelen auftritt.It can also be seen from FIG. 2 that in the gap area 15 between the surface areas 10 and 11 in the end zone of the covering area, when the pivot position between the adjacent panels changes from the door leaf open position to the door leaf closed position, a seal 33 in the form of a perpendicular to the direction of movement of the door leaf, that is, sealing strip extending in the direction of the width of the panels 4 is provided, which is inserted into a correspondingly extending sealing receiving groove 34 formed in the surface area 10 of the upward-facing end face 8. This ensures that the friction caused by the attack of the seal 33 on the other, opposite surface area 11 of the downward face 9 of the upper panel 4 in the closed position occurs only over a relatively small end pivoting angle range between the panels.

Die Paneele nach dem Ausführungsbeispiel gemäß Figur 3 sind jeweils als doppelwandiger Korpus ausgebildet, der durch eine die Außenwandung 35 und die beiden Stirnseiten 8 und 9 sowie an diese anschließende Randbereiche 24 aufweisende Außenschale 30 und durch eine die Rückwand 41 bildende Abdeckung 42 zusammengebaut ist. Die Abdeckung 42 ist mit durch Umfaltungen auf sich selbst verstärkten Randabschnitten 43 auf die durch umgefaltete Wandungsabschnitte 25 verstärkten Randbereiche 24 der Außenschale 30 aufgelegt, so daß die Scharnierlappen 26 und 27 mit den verstärkten Randabschnitten 43 und den verstärkten Randbereichen 24, 25 der Außenschale 30 durch strichpunktiert angedeutete Verschraubungen 26 verbunden sind. Die zum Inneren des jeweils zugehörigen Paneels 4 bzw. 4' hin abragenden Ränder der Randabschnitte 43 der Rückwand 41 sind mit Klippkanten 45 versehen, die die Umfaltungsbereiche zwischen den Randbereichen 24 und deren auf sich selbst zurückgefalteten Wandungsabschnitte 25 nach Art eines Schneppers federelastisch übergreifen. Auf diese Weise lassen sich die Außenschale 30 und die Rückwand 41 vor der Verschraubung mit den Scharnierlappen 2 und 27 im Sinne einer einfachen Vormontage miteinander verbinden. Die Paneele können mit einer Isoliermasse 32 beispielsweise ausgeschäumt sein. Im übrigen sind die Konturen der Stirnseiten 8 und 9, die Scharniere und die Dichtung nach Art und Ausbildung so getroffen wie bei dem Ausführungsbeispiel nach Figur 2.The panels according to the exemplary embodiment according to FIG. 3 are each designed as a double-walled body which is assembled by an outer shell 30 which has the outer wall 35 and the two end faces 8 and 9 and border regions 24 adjoining these and by a cover 42 which forms the rear wall 41. The cover 42 is placed with edge portions 43 reinforced by itself on the edge portions 24 of the outer shell 30 reinforced by folded-over wall portions 25, so that the hinge tabs 26 and 27 with the reinforced edge portions 43 and the reinforced edge portions 24, 25 of the outer shell 30 pass through Connections 26 indicated by dash-dotted lines are connected. The edges of the edge sections 43 of the rear wall 41 projecting towards the interior of the associated panel 4 or 4 'are provided with clip edges 45 which overlap the fold-over areas between the edge areas 24 and their wall sections 25 folded back onto themselves in the manner of a snapper. In this way, the outer shell 30 and the rear wall 41 can be connected to one another before the screwing with the hinge tabs 2 and 27 in the sense of a simple pre-assembly. The panels can be foamed with an insulating compound 32, for example. Otherwise, the contours of the end faces 8 and 9, the hinges and the seal are of the same type and design as in the exemplary embodiment according to FIG. 2.

Das Ausführungsbeispiel nach Figur 4 unterscheidet sich von demjenigen nach Figur 3 durch eine verdickte Paneelausbildung derart, daß die Außenschalen 59 im Bereich der Stirnseitenwandungen 63 und 64 der Stufenbereiche 19 und 20 länger ausgebildet sind. Im übrigen umfassen die Außenschalen 59 wiederum die Außenwandung 35 sowie die Randbereiche 24 nebst deren Umfaltungen, wie dies im Zusammenhang mit Figur 3 beschrieben wurde. Aufgrund der länger ausgebildeten Stirnseitenwandungen 63 und 64 greift die Scharnierachse 13 entsprechend weiter in das Innere der Paneele ein, wie dies Figur 4 erkennen läßt. Es ergeben sich insoweit bei der Verschwenkung dieselben Verhältnisse hinsichtlich der Formgebung der Oberflächenbereiche 10 und 11 wie bei den Beispielen nach den Figuren 2 und 3, was auch für die Dichtung 33 gilt. Auch diese Paneele können mit einer Isoliermasse 32 ausgeschäumt sein. Die Anordnungen und Ausbildungen im Bereich der Verbindung zwischen Außenschale und Rückwand entsprechen denjenigen des Ausführungsbeispiels gemäß Figur 3, und die Ausbildung des Scharnieres 12 unterscheidet sich insoweit nur durch an die Stirnseitenwandungen 63 und 64 angepaßt längere Bemessungen der Zwischenstege 72.The embodiment according to FIG. 4 differs from that according to FIG. 3 by a thickened panel construction in such a way that the outer shells 59 are longer in the area of the end walls 63 and 64 of the step areas 19 and 20. Otherwise, the outer shells 59 in turn include the outer wall 35 and the edge regions 24, together with their folds, as was described in connection with FIG. 3. Due to the longer side walls 63 and 64, the hinge axis 13 engages correspondingly further into the interior of the panels, as can be seen in FIG. In this respect, the same relationships with regard to the shape of the surface regions 10 and 11 result from the pivoting as in the examples according to FIGS. 2 and 3, which also applies to the seal 33. These panels can also be foamed with an insulating compound 32. The arrangements and configurations in the area of the connection between the outer shell and the rear wall correspond to those of the exemplary embodiment according to FIG. 3, and the configuration of the hinge 12 differs only in this respect by longer dimensions of the intermediate webs 72 adapted to the end walls 63 and 64.

Bei dem Ausführungsbeispiel nach Figur 5 weisen die Paneele 4 und 4' jeweils Rahmen 47 auf, deren jeder einen randseitigen Abschnitt der Außenwandung 35, die Stirnseiten 8 und 9 und die Randbereiche 24 bzw. einen diese bildende Randabschnitt der Rückwandung 41 für die Halterung der Scharnierlappen 26 und 27 umfaßt. Die Gestaltung der Stirnseiten und die Ausbildung und Anordnung der Scharniere 12 entspricht wie diejenige der Dichtung 33 den Verhältnissen wie beim Ausführungsbeispiel nach den Figuren 2 und 3. In den von den jeweiligen Rahmen 47 eingefaßten Raum ist eine Verglasung oder Blende eingesetzt. Der Rahmen 47 kann aus Metall - beispielsweise Blech oder Leichtmetall -, Kunststoff und/oder Holz bestehen.In the exemplary embodiment according to FIG. 5, the panels 4 and 4 'each have frames 47, each of which has an edge-side section of the outer wall 35, the end faces 8 and 9 and the edge regions 24 or an edge section of the rear wall 41 forming this, for holding the hinge tabs 26 and 27 includes. The design of the end faces and the training and arrangement The opening of the hinges 12, like that of the seal 33, corresponds to the conditions as in the exemplary embodiment according to FIGS. 2 and 3. In the space enclosed by the respective frame 47, glazing or a panel is inserted. The frame 47 can consist of metal - for example sheet metal or light metal -, plastic and / or wood.

Das Ausführungsbeispiel nach Figur 6 weist eine Abwandlung desjenigen nach Figur 5 dahingehend auf, daß ein Wärmeübergang von der einen Torblattseite zur anderen behindert ist. Zu diesem Zweck weisen die Rahmen 47 der Paneele 4 und 4' jeweils einen an der Torblattaußenseite 17 gelegenen Rahmenteil 74 und einen an der Torblattinnenseite 18 gelegenen Rahmenteil 75 auf. Beide Rahmenteile 74 und 75 sind in Richtung der Paneeldikke durch zwischen ihnen brückenförmig festgelegte, wärmeisolierende Kunststoffstege 76 verbunden und aneinander festgehalten. Die Kunststoffstege sind gegen höhere Temperaturen beständig. Die nach oben gerichtete Stirnwand des aus den beiden Rahmenteilen 74 und 75 gebildeten Rahmens 47 weist zwischen diesen Rahmenteilen einen Isolierkörper 77 auf, der einen Teil des den Spaltbereich 15 begrenzenden Polygonzuges des konvexen Oberflächenbereichs 10 und zumindest einen Teil des Stirnseitenbereiches bzw. der Anlagefläche 61 des Spaltbereiches 60 bildet. Der Isolierkörper ist zugleich als Dichtungsleiste ausgebildet, so daß eine solche im zur Torblattaußenseite 17 hin gerichteten Endbereich des Spaltbereiches 15 als gesonderte Dichtleiste entfallen kann. Auch ist die Mündung des Spaltbereiches 15 an der Außenseite 18 nicht als Nachbildung einer Sicke gestaltet, weil solche Sicken bei den hier in Rede stehenden Rahmenbauweisen der Paneele sich über deren Erstreckung in Bewegungsrichtung wiederholend nicht vorgesehen sind.The exemplary embodiment according to FIG. 6 has a modification of that according to FIG. 5 in that heat transfer from one side of the door leaf to the other is impeded. For this purpose, the frames 47 of the panels 4 and 4 'each have a frame part 74 located on the outside of the door leaf 17 and a frame part 75 located on the inside of the door leaf 18. Both frame parts 74 and 75 are connected in the direction of the panel thickness by means of heat-insulating plastic webs 76 which are defined in a bridge-like manner between them and are held together. The plastic bars are resistant to higher temperatures. The upward-facing end wall of the frame 47 formed from the two frame parts 74 and 75 has an insulating body 77 between these frame parts, which forms part of the polygonal shape of the convex surface area 10 delimiting the gap area 15 and at least part of the end face area or the contact surface 61 of the Gap area 60 forms. The insulating body is at the same time designed as a sealing strip, so that such a sealing strip in the end region of the gap region 15 directed towards the outside of the door leaf 17 can be dispensed with. Also, the mouth of the gap area 15 on the outside 18 is not designed as a replica of a bead, because such beads are not repeatedly provided in the frame construction of the panels in question because of their extension in the direction of movement.

Das Ausführungsbeispiel gemäß Figur 7 unterscheidet sich von demjenigen gemäß Figur 2 durch die Ausbildung der Scharniereinrichtung bzw. der Scharniere 12: Die Scharniere gemäß Ausführungsbeispiel 2 sind derart ausgebildet, daß jeder Scharnierlappen 26 und 27 einen sich parallel zur Torblattinnenseite 18 des jeweils anzuschließenden Paneels 4 bzw. 4' verlaufenden Befestigungsbereich 71 und einen demgegenüber zur Torblattaußenseite 17 hin schräg, beispielsweise um einen Winkel größer 30°, aus der Ebene des Befestigungsbereiches 71 von diesem abgebogen verlaufenden Zwischensteg 72 sowie einen sich an letzteren anschließenden, die Scharnierachse 13 umgreifenden Rollungsabschnitt 43 aufweist, der im Anschlußbereich an den Zwischensteg 72 auf einen der Torblattaußenseite 17 zugewandten Mantelbereich der Scharnierachse 13 aufläuft. Bei dem Ausführungsbeispiel gemäß Figur 7 sind dagegen Scharniere 12' eingesetzt, deren jeder Scharnierlappen 26' und 27' einen sich parallel zur Torblattinnenseite 18 des jeweils anzuschließenden Paneels 4 bzw. 4' verlaufenden Befestigungsbereich 71' und einen sich in gleicher Ebene oder zum Paneelinneren geneigt verlaufenden Zwischensteg 72' sowie einen sich an letzteren anschließenden, die Scharnierachse 13' umgreifenden Rollungsabschnitt 73' aufweist, der mit seinem an den Zwischensteg anschließenden Anfangsbereich auf einen von der Torblattaußenseite 17 abgewandten Mantelbereich der Scharnierachse aufläuft. Selbstverständlich sind für die Verschwenkbewegung der Scharnierlappen um die Scharnierachse herum erforderliche Ausnehmungen in den Zwischenstegen der Scharnierlappen entsprechend dem größten Verschwenkwinkel vorgesehen.The embodiment according to FIG. 7 differs from that according to FIG. 2 by the design of the hinge device or the hinges 12: the hinges according to embodiment 2 are designed such that each hinge flap 26 and 27 has a panel 4 or panel 4, which is parallel to the inside of the door leaf 18 4 'extending fastening area 71 and, in contrast, inclined toward the outer side 17 of the door leaf, for example at an angle greater than 30 ° , from the plane of the fastening area 71, which has an intermediate web 72 bent therefrom and also has a rolling section 43 which adjoins the latter and encompasses the hinge axis 13, that runs in the connection area to the intermediate web 72 onto a jacket area of the hinge axis 13 facing the door leaf outside 17. In the exemplary embodiment according to FIG. 7, on the other hand, hinges 12 'are used, each of which hinge tabs 26' and 27 'has a fastening area 71' which runs parallel to the inside of the door leaf 18 of the panel 4 or 4 'to be connected in each case and which is inclined in the same plane or to the interior of the panel extending intermediate web 72 'and a rolling portion 73' which adjoins the latter and encompasses the hinge axis 13 'and which, with its initial region adjoining the intermediate web, runs onto a jacket region of the hinge axis which faces away from the outside of the door leaf 17. Of course, for the pivoting movement of the hinge flaps around the hinge axis, recesses are provided in the intermediate webs of the hinge flaps corresponding to the largest pivoting angle.

Das Ausführungsbeispiel gemäß Figur 8 entspricht hinsichtlich der Scharnierausbildung und Scharnieranordnung dem Ausführungsbeispiel gemäß Figur 3, jedoch ist die Ausbildung der konvexen und konkaven Oberflächenbereiche 10 und 11 sowie die Lage des Spaltabschnittes 20 anders getroffen. Der konvexe Oberflächenbereich 10 der nach oben gerichteten Stirnwandung 8 des unteren Paneels 4' weist weitgehend den Polygonzug aus den Abschnitten 50, 51 und 52 sowie die Aufnahmenut 34 für die Dichtung 33 auf. Der konkave Oberflächenbereich 11 der nach unten gerichteten Stirnseite 9 des oberen Paneels 4 ist dagegen aus zwei Abschnitten 48 und 49 gebildet, die unmittelbar an die Wandung des Stufenbereiches 20 dieser Stirnseite anschließen. Damit bilden diese Abschnitte mit der Wandung fast eine U-förmige Rille. Die Nasenkante 23 ist jedoch erhalten geblieben und verschwenkt gegenüber dem konvexen Oberflächenbereich 10 in vergleichbarer Weise wie beim Ausführungsbeispiel gemäß Figur 3 bzw. 2. Der Spaltabschnitt 20 ist in den Bereich der Stufenbereiche 19 und 20 verlegt, d.h. der Stirnseitenbereich bzw. die Anlagefläche des Spaltabschnittes 20 wird von einem Teil 62' der Stirnwandung 64 des Stufenbereichs 20 gebildet und greift an einem Teilbereich 61' der Stirnwandung 63 des Stufenbereichs 19 an. Die Stirnwandung 63 ist zu diesem Zwecke gestuft ausgebildet, so daß der Scharnierbereich der Scharniereinrichtung 12 in einer annähernd U-förmigen Rinne Platz findet, während die im Spaltabschnitt 20 aneinanderliegenden Wandungsbereiche der Stirnwandungen 63 und 64 oberhalb der Scharnierachse 13 liegen, wie dies die Figur erkennen läßt, worauf ausdrücklich Bezug genommen wird.The embodiment according to FIG. 8 corresponds to the embodiment according to FIG. 3 with regard to the hinge configuration and hinge arrangement, but the configuration of the convex and concave surface regions 10 and 11 and the position of the gap section 20 are different. The convex surface area 10 of the upwardly directed end wall 8 of the lower panel 4 'largely has the polygon course from the sections 50, 51 and 52 and the receiving groove 34 for the seal 33. The concave surface area 11 of the downward face 9 of the upper panel 4, on the other hand, is formed from two sections 48 and 49, which directly adjoin the wall of the step area 20 of this face. These sections form almost a U-shaped groove with the wall. However, the nose edge 23 has been preserved and swiveled with respect to the convex surface area 10 in a manner comparable to that in the exemplary embodiment according to FIGS. 3 and 2. The gap section 20 is laid in the area of the step areas 19 and 20, i.e. the end face region or the contact surface of the gap section 20 is formed by a part 62 'of the end wall 64 of the step region 20 and engages a part region 61' of the end wall 63 of the step region 19. The end wall 63 is stepped for this purpose, so that the hinge area of the hinge device 12 can be accommodated in an approximately U-shaped groove, while the wall areas of the end walls 63 and 64 which lie against one another in the gap section 20 lie above the hinge axis 13, as can be seen in the figure leaves what is expressly referred to.

Figur 9 zeigt eine Abwandlung der Ausbildung des Beispieles nach Figur 8 bei einer dickeren Paneelausführung. Hier sind die Oberflächenbereiche 10 und 11 der Stirnseiten 8 und 9 vergleichbar wie beim Ausführungsbeispiel gemäß Figur 8 geschildert ausgebildet. Der Spaltabschnitt 20 befindet sich ebenfalls in der Eingriffszone der Stufenbereiche 19 und 20, jedoch hinsichtlich der im Spaltabschnitt 20 aneinanderliegenden Wandungsbereiche 61', 62' wiederum durch Stufungen der in Dickenrichtung der Paneele einander gegenüberliegenden Wandungen der Stufenbereiche 19 und 20. Die Stufungen 19 und 20 sind demnach jeweils als Doppelstufen ausgebildet, wie dies Figur 9 deutlich erkennen läßt. De Spaltabschnitt 20 liegt dabei deutlich oberhalb der Scharnierachse, was für die Verhinderung eines Fingereingriffes von zusätzlichem Vorteil ist.FIG. 9 shows a modification of the design of the example according to FIG. 8 with a thicker panel design. Here, the surface areas 10 and 11 of the end faces 8 and 9 are comparable to those in the exemplary embodiment according to FIG. 8 ge describes trained. The gap section 20 is also located in the engagement zone of the step regions 19 and 20, but with respect to the wall regions 61 ', 62' which are adjacent to one another in the gap section 20, again by steps of the walls of the step regions 19 and 20 lying opposite one another in the thickness direction of the panels. The steps 19 and 20 are accordingly designed as double stages, as can be clearly seen in FIG. 9. The gap section 20 is clearly above the hinge axis, which is an additional advantage for preventing finger intervention.

Das bei diesem Ausführungsbeispiel eingesetzte Scharnier 12 ist in bsonders einfacher Ausführung mit einer Scharnierachse 13 versehen, deren Verschwenkachse in der Fläche der Torblattinnenseite 18 verläuft, so daß das Scharnier nur teilweise zwischen den torblattinnenseitig gelegenen Abschnitten der Stirnwandungen 63 und 64 der Stufenbereiche 19 und 20 eingreift. Eine solche Scharnierausbildung läßt sich auch bei den vorgenannten Ausführungen einsetzen, und umgekehrt lassen sich Scharniere der bei den vorgenannten Ausführungen verwendeten Art bei diesem letzteren Ausführungsbeispiel verwenden, wobei sich die Formgebung der konvexen und konkaven Oberflächenbereiche gegebenenfalls etwas ändern kann, so daß die Nachzeichnung des Spaltbereiches 15 durch die Nasenkante 23 bei Verschwenken der Paneele gegeneinander derart erhalten bleibt, daß ein Fingereingriff zwischen die Paneele verhindert ist. Die zwischen den Einzelscharnieren verbleibenden Bereiche an der Torblattinnenseite 18 sind so bemessen, daß ein Fingereingriff verhindert bzw. derart möglich ist, daß ein Verschwenken der Paneele nicht zu einer Quetschung der Finger führt.The hinge 12 used in this embodiment is provided in a particularly simple version with a hinge axis 13, the pivot axis of which extends in the surface of the inside of the door leaf 18, so that the hinge only partially engages between the inner side of the door leaf sections of the end walls 63 and 64 of the step regions 19 and 20 . Such a hinge design can also be used in the aforementioned designs, and conversely, hinges of the type used in the aforementioned designs can be used in this latter embodiment, the shape of the convex and concave surface areas possibly changing somewhat, so that the tracing of the gap area 15 is retained by the nose edge 23 when the panels are pivoted relative to one another in such a way that finger engagement between the panels is prevented. The areas between the individual hinges on the inside of the door leaf 18 are dimensioned in such a way that finger engagement is prevented or possible in such a way that pivoting of the panels does not lead to crushing of the fingers.

Figur 10 gibt die stirnseitige oder Querschnittsdarstellung in Achsrichtung gesehen eines doppelschaligen Paneels 4 wieder, das aus durchscheinendem oder klarglasartigem Kunststoff besteht, beispielsweise durch Extrudieren gewonnen ist. Das Profil weist in den Anschlußbereichen der Scharnierlappen entsprechende Verstärkungen bzw. Hohlräume auf und ist im übrigen über seine Höhe gesehen mit in Dickenrichtung verlaufenden Versteifungsstegen versehen. Grundsätzlich könnte ein solches Paneel bei entsprechend versteifter bzw. dickwandigerer Ausführung auch einschalig ausgebildet sein. Man kann eine Vielzahl solcher lichtdurchlässigen Paneele zu einem Torblatt verbinden, oder aber auch nur ein oder einige der Paneele in dieser lichtdurchlässigen Form ausgebildet in eine Reihe von Paneelen lichtundurchlässiger Bauart einschalten, wodurch man einen entsprechenden Beleuchtungs- und/oder Fenstereffekt erhält.Figure 10 shows the frontal or cross-sectional view in the axial direction of a double-skin panel 4, which consists of translucent or clear glass-like plastic, for example, obtained by extrusion. The profile has corresponding reinforcements or cavities in the connection areas of the hinge tabs and is also provided with reinforcing webs running in the thickness direction, viewed over its height. In principle, such a panel could also have a single-shell design in the case of a correspondingly stiffened or thick-walled design. A large number of such translucent panels can be connected to form a door leaf, or just one or some of the panels formed in this translucent form can be switched into a series of panels of opaque construction, which gives a corresponding lighting and / or window effect.
