Abstract

The door leaf (1), in particular of an overhead sectional door, comprises a row of successively arranged, interlinked lamellae (4, 4'). For the purpose of a freer design of the overall door leaf structure and above all to make possible for transparent door leaf zones to be arranged in a simple manner, the door leaf is designed in such a manner that at least one single- or double-shell lamella (4) consists of transparent shell material and is inserted into the row of the other lamellae (4') which consist of non-transparent shell material. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Torblatt, insbesondere eines Überkopf-Sektionaltores, aus einer Reihe aufeinanderfolgend angeordneter, aneinander angelenkter Paneele, deren wenigstens eines als ein- oder doppelschalige Lamelle aus transparentem Werkstoff ausgebildet und in die Reihe der anderen, aus lichtundurchlässigem Schalenwerkstoff bestehenden Lamellen eingesetzt ist.The invention relates to a door leaf, in particular an overhead overhead door, consisting of a series of consecutively arranged, articulated panels, the at least one of which is designed as a single- or double-skin slat made of transparent material and inserted into the row of the other slats made of opaque shell material is.

Ein solches Torblatt aus einheitlich ausgestalteten Lamellen ist beispielsweise aus der GB-A-2.155.527 bekannt. Bei solchen Torblättern wurde dem Bedürfnis nach Durchblickmöglichkeiten bisher dadurch genügt, daß man in Lamellen aus lichtundurchlässigem Werkstoff, beispielsweise Stahlblech mit und ohne Isolierfüllung, fensterartige Öffnungen eingeschnitten und mit einem eine Kunstglasfensterscheibe enthaltenden Rahmen versehen hat, oder es wurden aneinander angelenkte Lamellen in Form von Rahmenkonstruktionen verwendet, in deren Rahmenfelder durchsichtige oder lediglich lichtdurchlässige, also milchglasähnliche oder durch sonstige Konfiguration bzw. Beigaben "halbdurchsichtige" transparente Scheibengebilde eingesetzt wurden; auch ist es in diesem Zusammenhang bekannt, einen Teil der Paneele des Torblattes zwischen den Verbindungen zum jeweiligen Nachbartorblatt lichtdurchlässig auszubilden oder zur Gänze aus lichtdurchlässigem Werkstoff herzustellen (US-A-1,983,098; DE-A-31.02.897).Such a door leaf made of uniformly designed slats is known for example from GB-A-2.155.527. In the case of door leaves of this type, the need for perspectives has hitherto been met by cutting window-like openings into slats made of opaque material, for example steel sheet with and without insulating filling, and providing them with a frame containing an artificial glass window pane, or slats articulated to one another in the form of frame structures used, in whose frame fields transparent or only translucent, ie frosted glass-like or "semitransparent" transparent pane structures were used by other configuration or additions; it is also known in this connection to make part of the panels of the door leaf between the connections to the respective neighboring door leaf translucent or to produce them entirely from translucent material (US Pat. No. 1,983,098; DE-A-31.02.897).

Bei Verwendung von unterschiedlichen Schalenwerkstoffen, so insbesondere lichtundurchlässige, metallische Schalenwerkstoffe einerseits und transparente Kunststoffe andererseits, wird vielfach ein so verschiedenes Wärmeausdehnungsverhalten auftreten, daß sich über die jahreszeitlichen Temperaturänderungen hin gesehen Probleme im Anlenkungsbereich der Lamellen unterschiedlicher Schalenwerkstoffe ergeben. Soweit beim vorgenannten Stand der Technik lichtundurchlässige Lamellen an lichtdurchlässige Lamellen angrenzen, sind die Gelenkverbindungen zwischen diesen durch hakenförmig ineinandergreifende, über die Lamellenbreite durchgehende Vorsprünge getroffen.When using different shell materials, in particular opaque, metallic shell materials on the one hand and transparent plastics on the other hand, such a different thermal expansion behavior will occur that, in view of the seasonal temperature changes, problems arise in the articulation area of the lamellae of different shell materials. Insofar as opaque slats border on translucent slats in the aforementioned prior art, the articulated connections between them are made by means of hook-like interlocking projections that extend across the slat width.

Der Erfindung liegt die Aufgabe zugrunde, ein Torblatt der eingangs genannten Art zu schaffen, das bei freier Gestaltung der gesamten Torblattausbildung mit lichtdurchlässigen Torblattzonen die Verbindung zwischen unterschiedlichen Lamellen unter Berücksichtigung der Temperatureinflüsse möglichst einfach auszubilden sind.The invention has for its object to provide a door leaf of the type mentioned that the connection between different slats are as simple as possible with free design of the entire door leaf formation with translucent door leaf zones, taking into account the temperature influences.

Diese Aufgabe wird durch die Verwendung von in Gelenkachsrichtung voneinander beabstandet angeordneten Einzelscharnieren gelöst, von denen alle bis auf eines eine Versetzbewegung von Lamellenabschnitten in Lamellenbreitenrichtung gesehen unter Wärmeeinfluß zulassen, und zwar auf verschiedene Weise, nämlich zum einen durch ein entsprechendes axiales Spiel zwischen den ineinandergreifenden Scharnierlappen der einzelnen Scharniere bis auf eines oder durch Anordnung der Scharnierlappen, die die Verbindung zu einer Lamelle aus transparentem Schalenwerkstoff herstellen, derart, daß im angrenzenden Kantenbereich dieser letzteren Lamelle eine Metallschiene engesetzt ist, an der die Scharnierlappen derart festgelegt sind, daß sie in Scharnierachsrichtung gesehen in breitere Öffnungen der Lamelle eingreifen, als die Scharnierlappen selbst breit sind. Beide Maßnahmen können kombiniert werden.This object is achieved by the use of individual hinges spaced apart from one another in the joint axis direction, all of which, except for one, permit a displacement movement of lamella sections in the lamella width direction under the influence of heat, in different ways, namely on the one hand through a corresponding axial play between the interlocking hinge tabs of the individual hinges except for one or by arranging the hinge lugs, which produce the connection to a lamella made of transparent shell material, in such a way that a metal rail is inserted in the adjacent edge region of this latter lamella, on which the hinge lobes are fixed such that they are seen in the hinge axis direction engage in wider openings in the slat than the hinge lugs themselves are wide. Both measures can be combined.

In einer der Ausführungen werden daher die Scharniere mit einem entsprechend dem unterschiedlichen Temperaturausdehnungsverhalten der Schalenwerkstoffe zwischen zwei Lamellen bemessenen axialen Spiel zwischen den Scharnierlappen ausgebildet, so daß sich die Befestigungsstellen der Scharnierlappen an der einen Lamelle einerseits und der anderen Lamelle andererseits gegeneinander in Scharnierachsrichtung verschieben können. Um eine solche Verschiebung nicht unnötig durch die Führung bzw. Laufrollen der einzelnen Lamellen begrenzen zu müssen, ist eines der Scharniere, insbesondere im in Scharnierachsrichtung gesehenen Mittelbereich der Lamelle, in Axialrichtung spielarm ausgebildet, so daß eine Lageausrichtung der Lamellen insbesondere in deren Mittelbereich über dieses Scharnier erfolgt.In one of the versions, therefore Hinges are designed with an axial play between the hinge tabs that is dimensioned according to the different temperature expansion behavior of the shell materials between two lamellas, so that the fastening points of the hinge tabs on the one lamella on the one hand and the other lamella on the other hand can shift relative to one another in the hinge axis direction. In order not to unnecessarily limit such a displacement by the guidance or rollers of the individual slats, one of the hinges, in particular in the central area of the slat seen in the direction of the hinge axis, is designed with little play in the axial direction, so that a positional alignment of the slats, in particular in their central area, over this Hinge is done.

Eine derartige in Axialrichtung spielbehaftete und damit eine Verschiebung der an den zu verbindenden Lamellen jeweils anzulegenden Scharnierlappen zulassende Ausbildung wenigstens aller Scharniere bis auf eines ist immer dann von Bedeutung, wenn mittels einer solchen Scharnierverbindung Lamellen aus Schalenwerkstoffen unterschiedlicher Temperaturausdehnung aneinander angelenkt werden sollen; insoweit ist diese Scharnierausbildung nicht an die Verwendung einer oder mehrerer Lamellen aus transparentem Werkstoff gebunden, sondern von selbständiger Bedeutung. Beispielsweise könnte man eine ausgeschäumte Stahlblechlamelle mit einer solchen axial spielbehafteten Scharnierverbindung an eine Lamelle anschließen, die aus Aluminium gebildet ist, ein Aluminiumprofil aufweist oder aus einem Aluminiumrahmen mit transparenten scheibenförmigen Gebilden besteht.
Des weiteren ist es möglich, eine aus transparentem Schalenwerkstoff bestehende Lamelle mit einer Metallkörpereinlage, insbesondere einer Schiene, beispielsweise aus Aluminium, zu versehen, an der die zugehörigen Scharnierlappen festgelegt werden. Für diesen Fall hat man es mit drei unterschiedlichen Temperaturausdehnungen zu tun, nämlich einmal derjenigen der lichtundurchlässigen Lamelle, beispielsweise Stahlblechlamelle, derjenigen der Aluminiumstange und derjenigen des transparenten Werkstoffes der an die vorerwähnte Lamelle angeschlossenen transparenten Lamelle. In einem solchen Fall kann es erforderlich sein, sowohl eine axial spielbehaftete Scharnierverbindung der vorstehend genannten Art als auch eine Zuordnung zwischen dem transparenten Schalenwerkstoff und der eingelegten Metallstange vorzusehen, die eine in Scharnierachsrichtung gesehene Versetzbarkeit zwischen dem transparenten Schalenprofil und der Metallstange erlaubt. Natürlich wäre es auch möglich, die Metallstange aus demselben Werkstoff bzw. einem Werkstoff mit annähernd demselben Temperaturausdehnungskoeffizienten zu wählen, wie die angeschlossene Lamelle aus lichtundurchlässigem Werkstoff, beispielsweise also in beiden Fällen Stahl. Dann könnte man auf das axiale Scharnierspiel verzichten und lediglich dasjenige zwischen dem transparenten Lamellenprofil und der in dieses eingelegten Metallstange vorsehen. Auch hier ist es wie bei der spielbehafteten Scharnierverbindung von Vorteil, insbesondere im Mittelbereich eine insoweit spielfreie Anpassung zwischen dem Scharnierlappen und der diesen aufnehmenden Öffnung des transparenten Schalenprofiles vorzusehen. Dieser Mittelbereich arbeitet dann als axiales Festlager, während die übrigen Durchtrittsöffnungen gegenüber den in ihnen aufgenommenen Scharnierlappen ein axiales Spiel aufweisen, das man als Loslager bezeichnen könnte.Such an embodiment, which is subject to play in the axial direction and thus permits a displacement of the hinge tabs to be applied to the slats to be connected in each case, at least all but one of the hinges is always of importance if by means of a such hinge connection slats made of shell materials of different temperature expansion should be hinged together; In this respect, this hinge design is not tied to the use of one or more slats made of transparent material, but of independent importance. For example, one could connect a foamed steel sheet lamella with such a hinge connection with axial play to a lamella which is formed from aluminum, has an aluminum profile or consists of an aluminum frame with transparent disk-shaped structures.
Furthermore, it is possible to provide a lamella made of transparent shell material with a metal body insert, in particular a rail, for example made of aluminum, on which the associated hinge tabs are fixed. In this case, there are three different temperature expansions, namely that of the opaque lamella, for example sheet steel lamella, that of the aluminum rod and that of the transparent material of the transparent lamella connected to the aforementioned lamella. In such a case, it may be necessary to provide both an axially free-play hinge connection of the type mentioned above and an assignment between the transparent shell material and the inserted metal rod, which has a displaceability between the hinge axis direction the transparent shell profile and the metal rod allowed. Of course, it would also be possible to choose the metal rod from the same material or a material with approximately the same coefficient of thermal expansion as the connected lamella made of opaque material, for example steel in both cases. Then one could do without the axial hinge play and only provide that between the transparent slat profile and the metal rod inserted into it. Here too, as in the case of the hinge connection with play, it is advantageous, in particular in the middle region, to provide an adaptation free of play between the hinge flap and the opening in the transparent shell profile which receives it. This central region then works as an axial fixed bearing, while the other passage openings have an axial play relative to the hinge lugs accommodated in them, which could be called a floating bearing.

Figur 1 zeigt ein insgesamt mit 1 bezeichnetes Torblatt, das in der Schließstellung 2 mit durchgezogenen Strichen wiedergegeben ist, während die gestrichelte Wiedergabe des Torblattes bzw. der Lamellen annähernd die Öffnungsstellung 3 des Torblattes erkennen läßt. Die in der Schließstellung etwa in Augenhöhe gelegene, aus transparentem Kunststoff gebildete Lamelle ist mit 4, die übrigen, darüber und darunter gelegenen Lamellen, die lichtundurchlässig aus zwei Stahlblechschalen mit einer Isolierschaumfüllung ausgebildet sind, tragen die Bezeichnung 4′. 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 vertikal verlaufenden geradlinigen Abschnitt für die Einnahme der Schließstellung des Torblattes, einem bogenförmigen Übergangsabschnitt und einem etwa horizontal geradlinig verlaufenden Abschnitt für die Aufnahme des Torblattes in der Öffnungstellung zusammen. Für die obere Rolle der in der Schließstellung obersten Lamelle ist eine gesonderte horizontale Führung mit schräg verlaufendem Übergangsstück 6′ vorgesehen, um die oberste Lamelle bei geringer Sturzhöhe in die Schließlage zu überführen, wie dies Figur 1 erkennen läßt. In der Schließlage bildet das Torblatt eine nach außen gerichtete Außenseite und eine ins Innere des zu verschließenden Raumes gerichtete Innenseite.Figure 1 shows a door leaf generally designated 1, which is shown in the closed position 2 with solid lines, while the dashed representation of the door leaf or the slats almost reveals the open position 3 of the door leaf. The lamella, which is approximately at eye level in the closed position and is made of transparent plastic, is provided with 4 lamellae, the remaining lamellae, above and below, are made of two sheet steel shells with an insulating foam filling are trained, bear the designation 4 '. In the hinge area between the panels, rollers 5 are provided on these, which engage in guide rails 6, as is generally known for gates of this type. The guide rails are composed of a vertically running rectilinear section for taking the closed position of the door leaf, an arcuate transition section and an approximately horizontally rectilinear section for receiving the door leaf in the open position. For the upper role of the topmost slat in the closed position, a separate horizontal guide with an inclined transition piece 6 'is provided in order to transfer the uppermost slat into the closed position at a low lintel height, as can be seen in FIG. In the closed position, the door leaf forms an outside facing outside and an inside facing inside the room to be locked.

Das in Stirnseitenansicht wiedergegebene extrodierte Schalenprofil 8 einer Ausführungsform einer aus durchscheinendem oder hier entsprechend der Anordung in Augenhöhe als Fenster aus klarglasartigem Kunststoff hergestellten Lamelle 4 ist mit einer Außenschale 9 und einer dieser abgewandt und dem Inneren des mit dem Torblatt 1 zu verschließenden Raumes zugewandten Innenschale 10 versehen. Diese beiden Schalenteile 9 und 10 sind mit Hilfe von senkrecht dazu und sich in horizontaler Richtung erstreckenden Zwischenstegen 11 einstückig miteinander verbunden und begrenzen zwischen sich und den Stegen 11 Profil-Kammern 12, die mit Hilfe von an den schmalen Stirnseiten des Profiles 8 anzubringenden Abdeckungen 29 -Figuren 3 und 4- verschließbar sind. Die Außenschale 9 ist mit in Profilrichtung, also im Gebrauchszustand horizontal, verlaufenden Sicken 13 unterbrochen, die bei aneinander angelenkten Lamellen auch zwischen diesen in ähnlicher Form in Erscheinung treten. Die Seitenwandungen der Sicken 13 gehen in entsprechend angeordnete Zwischenstege 11 über bzw. werden durch diese gebildet. Am Bereich der oberen Stirnbreitseite 15 ist oberhalb des die oberste Kammer 12 nach oben hin begrenzenden Zwischensteges 11 eine Halterung 17 gebildet, die nach Art einer sich in Profillängsrichtung erstreckenden hinterschnittenen Nut ausgeformt ist. Diese Halterung 17 für einen nach oben hin abragenden Dichtungswulst schließt sich an die Außenschale 9 an und ist neben einem Profilhohlraum 26 ausgebildet, dessen nach innen gerichtete Abschlußwandung mit der Innenschale 10 fluchtet. In diesem Profilhohlraum 26 im Bereich der oberen Stirnbreitseite 15 ist eine Aluminiumstange 25 eingesetzt, die sich über die gesamte horizontale Breite des Profiles erstreckt und der Halterung der Scharniere 19 dient, wie dies durch den inneren Scharnierlappen 21 angedeutet wurde.The extruded shell profile 8 shown in the front view of an embodiment of a lamella 4 made of translucent plastic or, in this case, corresponding to the arrangement at eye level as a window made of clear glass-like plastic, has an outer shell 9 and one facing away from it and the inside of the inner shell 10 facing the door leaf 1 to be closed Mistake. These two shell parts 9 and 10 are perpendicular to it and extend in the horizontal direction Intermediate webs 11 are integrally connected to one another and delimit between themselves and the webs 11 profile chambers 12, which can be closed with the aid of covers 29 — figures 3 and 4 — to be attached to the narrow end faces of the profile 8. The outer shell 9 is interrupted by beads 13 which run horizontally in the profile direction, that is to say horizontally in the state of use, which also appear in a similar form between the slats articulated to one another. The side walls of the beads 13 merge into correspondingly arranged intermediate webs 11 or are formed by these. At the area of the upper front broad side 15, a holder 17 is formed above the intermediate web 11 which delimits the uppermost chamber 12 upwards and is shaped in the manner of an undercut groove extending in the longitudinal direction of the profile. This holder 17 for an upwardly protruding sealing bead connects to the outer shell 9 and is formed next to a profile cavity 26, the inward end wall of which is flush with the inner shell 10. In this profile cavity 26 in the region of the upper front broad side 15 an aluminum rod 25 is inserted, which extends over the entire horizontal width of the profile and serves to hold the hinges 19, as was indicated by the inner hinge flap 21.

An der in der Schließstellung 2 des Torblattes 1 nach unten gerichteten Stirnbreitseite 16 ist eine an die Außenschale 9 senkrecht anschließende und vorstehend ausgebildete Dichtfläche 18 ausgeformt, die sich wie die Halterung 17 im oberen Stirnbreitseitenbereich 15 über die Breite der Lamelle hinweg erstreckt und der Anlage des in die Halterung 17 der nächstfolgenden benachbarten Lamelle eingesetzten Dichtungswulstes dient.On the front broadside 16 facing downward in the closed position 2 of the door leaf 1 there is one on the Outer shell 9 formed vertically adjoining and above-formed sealing surface 18 which, like the holder 17, extends across the width of the lamella in the upper front broad side region 15 and serves to abut the sealing bead inserted into the holder 17 of the next adjacent lamella.

In gleicher Weise wie im oberen Stirnbreitseitenbereich 15 ist auch im unteren Stirnbreitseitenbereich 16 bzw. fluchtend anschließend an die Innenschale 10 ein weiterer Profilhohlraum 26 ausgebildet, der in gleicher Weise der Aufnahme einer Aluminiumstange 25 dient, so daß die Befestigung der Scharnierlappen im oberen und unteren Breitseitenbereich der Lamelle dieselbe ist. Lediglich zu Demonstrationszwecken wurde in Figur 2 eine andere Befestigungsalternative dargestellt, und zwar mit Hilfe einer Hülsenschraube 24, die durch die Profildicke hinweg geführt ist und deren den Schraubweg begrenzende Hülsenlänge so gewählt ist, daß bei Festziehen der Schraube nur ein verhältnismäßig geringer Druck auf die Schalen 9 und 10 ausgeübt wird. Auf diese Weise erreicht man eine Festlegung der Scharnierlappen unmittelbar an dem Profil, ohne Gefahr zu laufen, daß durch entsprechendes Anziehen der Schrauben das Profil zerstört wird.In the same way as in the upper front broad side region 15, a further profile cavity 26 is also formed in the lower front broad side region 16 or in alignment with the inner shell 10, which in the same way serves to accommodate an aluminum rod 25, so that the hinge tabs are fastened in the upper and lower broad side region the lamella is the same. Another fastening alternative was shown in FIG. 2 only for demonstration purposes, namely with the aid of a sleeve screw 24 which is guided through the profile thickness and whose sleeve length limiting the screw path is selected such that when the screw is tightened only a relatively small pressure on the shells 9 and 10 is exercised. In this way, the hinge flaps are fixed directly to the profile without running the risk that the profile will be destroyed by appropriate tightening of the screws.

Das Profil kann aus einem klarglasartigen Kunststoff wie Polycarbonat, Plexiglas oder ähnlichem mit glatter oder strukturierter Oberfläche hergestellt sein, es kann aber auch lediglich durchscheinend weiß oder in diversen Farben zur Verfügung gestellt werden, wenn eine fensterartige Durchblickmöglichkeit nicht vorgesehen sein soll. Darüber hinaus können insbesondere durch mechanische Oberflächenbehandlung der Schalenteile glasklare Fensterbereiche verbleiben, während die um diese herumliegenden Schalenflächen lediglich noch milchglasartig durchscheinend sind; dies kann man beispielsweise durch Herstellung der Lamelle aus glasklarem Kunststoff, anschließendem Abdecken bzw. Abkleben der Fensterbereiche und daran anschließendes Sandstrahlen oder dgl. erreichen.The profile can be made of a clear glass-like plastic such as polycarbonate, plexiglass or the like with a smooth or structured surface, however, it can also be made available in translucent white or in various colors if a window-like view is not to be provided. In addition, crystal-clear window areas can remain, in particular due to mechanical surface treatment of the shell parts, while the shell surfaces lying around them are only translucent like frosted glass; this can be achieved, for example, by producing the lamella from crystal-clear plastic, then covering or masking off the window areas and then sandblasting or the like.

Figur 3 ist eine Breitenansicht auf den Scharnierbereich zwischen zwei Lamellen, deren in der Darstellung obere 4′ als zweischalige Blechlamelle mit Isolierfüllung ausgebildet ist, während die in der Darstellung untere Lamelle 4 aus transparentem bzw. klarglasartigem Kunststoff besteht und hinsichtlich der Scharnierlappenbefestigung mit den vorerwähnten Hülsenschrauben arbeitet.Figure 3 is a width view of the hinge area between two slats, the upper 4 'in the illustration is formed as a double-skin sheet metal lamella with insulating filling, while the lower lamella 4 in the illustration consists of transparent or clear glass-like plastic and with respect to the hinge flap attachment with the aforementioned sleeve screws is working.

Zwischen beiden Lamellen 4′ und 4 ist eine ungerade Anzahl von Scharnieren angeordnet, von denen nur das im Breitenmittelbereich der Lamellen angeordnete Scharnier 19′ und die beiden randseitigen Scharniere 19 wiedergegeben sind. Die an der oberen, lichtundurchlässigen Blechlamelle 4′ angeordneten Scharnierlappen 20 dieser Scharniere sind in herkömmlicher Weise an der Lamelle festgelegt, während die der unteren, klar durchsichtigen Lamelle 4 zugeordneten Scharnierlappen 21 der Scharniere 19 und 19′ mit Hilfe der vorerwähnten Hülsenschrauben unmittelbar an dem doppelschaligen Paneeleprofil befestigt sind. Bei Temperaturunterschieden, wie sie über den Jahresablauf hinweg gesehen auftreten, ergeben sich hinsichtlich der Blechlamelle 4′ und der Kunststofflamelle 4 je nach Material mehr oder weniger große Temperaturausdehnungsunterschiede, was bei Verwendung normaler Scharniere zu Spannungen, Verwerfungen bzw. Zerstörungen führen würde. Aus diesem Grunde sind die Scharniere 19 als "Loslager" derart ausgebildet, daß zwischen den Scharnierlappen 20 und 21 in Richtung der Scharnierachse 22 gesehen eine Verschiebemöglichkeit gegeben ist. Dies läßt sich aus der Zeichnung deutlich entnehmen. Hier sind mittlere Temperaturen angenommen, es kann sich also in Richtung niedrigerer Temperatur eine Verschiebung in der einen und in Richtung höherer Temperatur eine Verschiebung in der anderen Richtung der Scharnierachse vollziehen. Im vorliegenden Beispiel ist dies dadurch erreicht, daß die Scharnierlappen 20 gabelförmig mit entsprechend weitem Gabelabstand ausgebildet sind, während der Verschwenkteil des Scharnierlappens 21, der in die Gabel des Scharnierlapens 20 eingreift, wesentlich schmaler als diese ausgebildet ist.Between the two slats 4 'and 4 an odd number of hinges is arranged, of which only the hinge 19' arranged in the central width region of the slats and the two edge-side hinges 19 are shown. The on the upper, opaque sheet metal plate 4 'arranged hinge tabs 20 of these hinges are fixed in a conventional manner on the slat, while that of the lower, clear transparent lamella 4 associated hinge tabs 21 of the hinges 19 and 19 'are attached directly to the double-skin panel profile with the aid of the aforementioned sleeve screws. With temperature differences, such as occur over the course of the year, there are more or less large differences in temperature expansion with regard to the metal plate 4 'and the plastic plate 4, which would lead to tension, warping or destruction if normal hinges were used. For this reason, the hinges 19 are designed as a “floating bearing” in such a way that there is a possibility of displacement between the hinge tabs 20 and 21 in the direction of the hinge axis 22. This can be clearly seen from the drawing. Average temperatures are assumed here, so there can be a shift in one direction in the direction of lower temperature and a shift in the other direction of the hinge axis in the direction of higher temperature. In the present example, this is achieved in that the hinge flaps 20 are fork-shaped with a correspondingly wide fork spacing, while the pivoting part of the hinge flap 21, which engages in the fork of the hinge flap 20, is substantially narrower than this.

Um zu vermeiden, daß die benachbarten aneinander angelenkten Lamellen sich über das gesamte Loslagerspiel willkürlich in der einen oder in der anderen Richtung bewegen können, so daß nur die Rollen in den Rollenführungen die Lageposition bestimmen müssen, was zu entsprechenden Reibungsverlusten führt, ist das in Scharnierachsrichtung gesehen im Breitenmittelbereich der Lamellen angeordnete Scharnier 19′ als "Festlager" ausgebildet, d.h. das im Zusammenhang mit den anderen Scharnieren 19 geschilderte Loslagerspiel ist dort nicht vorhanden bzw. durch Abstandshülsen 23 unterbunden, die beidseitig des Gelenkteils des Scharnierlappens 21 zwischen diesem und den Gabelausbildungen der Scharnierlappen 20 angeordnet sind, wie dies die Figuren 3 bis 5 zeigen. Durch den Einsatz dieser Abstandshülsen 23 wird eine identische Ausbildung sämtlicher Scharnierlappen ermöglicht, was von herstellungstechnischem Vorteil ist. Selbstverständlich könnte man auch hinsichtlich des Scharnieres 19′ ein solches verwenden, das in bekannter Weise von Hause aus in axialer Richtung zwischen den Scharnierlappen praktisch spielfrei arbeitet.In order to avoid that the adjacent slats articulated to one another can move arbitrarily in one or the other direction over the entire floating bearing play, so that only the rollers in the Roller guides have to determine the position, which leads to corresponding friction losses, the hinge 19 'arranged in the hinge axis direction in the central width region of the slats is designed as a "fixed bearing", ie the bearing play described in connection with the other hinges 19 is not present there or by spacers 23 prevented, which are arranged on both sides of the hinge part of the hinge flap 21 between the latter and the fork configurations of the hinge flap 20, as shown in FIGS. 3 to 5. The use of these spacer sleeves 23 enables all hinge tabs to be designed identically, which is of advantage in terms of production technology. Of course, one could also use one with regard to the hinge 19 ', which works in a known manner practically without play in the axial direction between the hinge tabs.

Bei dem Ausführungsbeispiel gemäß 4 ist die klarglasartige Lamelle 4 so ausgebildet, wie dies die Profildarstellung gemäß Figur 2 zeigt. Um eine bessere Lastverteilung hinsichtlich der Scharnieranschlüsse zu erreichen, sind Aluminiumstangen 25 vorgesehen, die in Profilhohlräume 26 eingeschoben sind, wie dies Figur 2 zeigt. Dabei könnte man grundsätzlich die Scharnierlappen von außen auf die Innenschale 10 aufsetzen und durch den Kunststoff in die Metallschiene 25 einschrauben. Das wäre insbesondere für den Fall möglich, daß Kunststoff- und Metallschiene einen etwa gleichen Temperaturausdehnungskoeffizienten haben, was jedoch grundsätzlich nicht der Fall sein dürfte. Dann müßte man in dem Kunststoff im Bereich der Befestigungsschrauben Langlöcher einbringen. Eine andere Lösung zeigt Figur 4 dergestalt, daß im Bereich der an die Lamelle 4 anzuschließenden Scharnierlappen 21 Aussparungen in der an die Innenschale 10 anschließenden Wandung des Profilhohlraumes 26 eingebracht sind.Dabei werden mit Ausnahme der Aussparung, die den Scharnierlappen 21 des im Mittelbereich des Paneeles angeordneten Scharnieres 19′ aufnimmt, die Aussparungen der übrigen Scharniere in Achsrichtung des Scharniers gesehen größer ausgebildet, es werden somit Öffnungen 27 freigelassen, die eine unterschiedliche Temperaturausdehnung zwischen dem Scharnierlappen 21 bzw. der Stange 25 und dem Schalenprofil 8 der Lamelle 4 ermöglichen. Da die Temperaturausdehnung zwischen der Stahlblechlamelle 4′ und der Aluminiumstange 25 ebenfalls unterschiedlich ist, werden Scharniere 19 bzw. 19′ verwendet, wie sie im Zusammenhang mit Figur 3 beschrieben und hinsichtlich ihrer Funktion erläutert worden sind.In the exemplary embodiment according to FIG. 4, the clear glass-like lamella 4 is designed as shown in the profile illustration according to FIG. 2. In order to achieve a better load distribution with regard to the hinge connections, aluminum rods 25 are provided which are inserted into profile cavities 26, as shown in FIG. 2. In principle, the hinge tabs could be placed on the inner shell 10 from the outside and screwed into the metal rail 25 through the plastic. That would be especially the case possible that plastic and metal rails have approximately the same coefficient of thermal expansion, but this should not be the case in principle. Then you would have to make elongated holes in the plastic in the area of the fastening screws. Another solution is shown in FIG. 4 in such a way that, in the area of the hinge lugs 21 to be connected to the lamella 4, recesses are made in the wall of the profile cavity 26 adjoining the inner shell 10. With the exception of the recess, the hinge lobe 21 in the central area of the panel Arranged hinge 19 'takes, the recesses of the other hinges seen larger in the axial direction of the hinge, openings 27 are thus left open, which allow a different temperature expansion between the hinge tab 21 or the rod 25 and the shell profile 8 of the slat 4. Since the temperature expansion between the sheet steel plate 4 'and the aluminum rod 25 is also different, hinges 19 and 19' are used, as described in connection with Figure 3 and explained with regard to their function.

Bei dem Ausführungsbeispiel gemäß Figur 5 ist die untere Lamelle 4˝ nicht wie die übrigen als Schalenprofil ausgebildet, sondern weist einen - beispielsweise aus Aluminium bestehenden - Rahmen 30 auf, welcher - gegebenenfalls mit einer Reihe von Unterteilungen - klarglasartige oder halbdurchsichtige, in grundsätzlicher Möglichkeit aber auch lichtundurchlässige Scheiben aufnimmt. Der Aluminiumrahmen ist mit Hilfe der Scharniere 19 und 19′ unmittelbar an die Stahlblechlamelle 4′ angeschlossen, so daß sich ähnliche Verhältnisse wie im Zusammenhang der Verbindung zwischen der Stahlblechlamelle 4′ und der Aluminiumstange 25 der Lamelle 4 in Figur 4 ergeben. Mit Ausnahme des im Mittelbereich angeordneten Scharnieres 19′ sind die übrigen Scharniere 19 - hier wiederum nur die beiden außenseitigen dargestellt - mit einem axialen Spiel zwischen den Scharnierlappen 20 und 21 ausgeführt, so daß die unterschiedliche Temperaturausdehnung zwischen Stahl und Aluminium sich entsprechend in einer axialen Verschiebung zwischen den Scharnierlappen 20 und 21 der Scharniere 19 auswirken kann und somit keine temperaturbedingten Spannungen und Zerstörungsgefahren auftreten.In the exemplary embodiment according to FIG. 5, the lower lamella 4˝ is not designed as a shell profile like the others, but instead has a frame 30, for example made of aluminum, which - optionally with a number of subdivisions - is clear glass-like or semi-transparent, in basic possibility but also opaque panes. The aluminum frame is connected by means of hinges 19 and 19 'directly to the sheet steel plate 4', so that there are similar conditions as in connection with the connection between the sheet steel plate 4 'and the aluminum rod 25 of the plate 4 in Figure 4. With the exception of the hinge 19 'arranged in the central region, the remaining hinges 19 - here again only the two outside are shown - with an axial play between the hinge tabs 20 and 21, so that the different temperature expansion between steel and aluminum correspondingly in an axial displacement can affect between the hinge tabs 20 and 21 of the hinges 19 and thus no temperature-related tensions and risk of destruction occur.
