Description

Die Erfindung betrifft eine Faltanlage mit oben- und untenseitig in Führungsschienen geführten Faltflügeln nach dem Oberbegriff des Anspruchs 1. Dabei können zum Öffnen die Flügel der Faltanlage in den Führungsschienen verschoben und/oder aus diesen heraus verschwenkt werden. In geschlossener Position bedarf es einer Verriegelung. Dazu ist ein Verriegelungsbeschlag im Rahmenprofil von zumindest einem der Faltflügel aufgenommen. Über ein Verriegelungsgetriebe können Verriegelungszapfen zumeist oben und unten in die Führungsschiene hineinbewegt werden, bzw. aus dieser hinaus, wenn die Anlage wieder geöffnet werden soll.The invention relates to a folding system with folding wings guided in guide rails at the top and bottom according to the preamble of claim 1. The wings of the folding system can be moved in and / or pivoted out of the guide rails for opening. A lock is required in the closed position. For this purpose, a locking fitting is received in the frame profile of at least one of the folding sashes. Locking pins can usually be moved up and down into the guide rail via a locking gear, or out of this when the system is to be opened again.

Um einer verbesserten Absicherung Rechnung zu tragen, wird in der EP 2 275 632 B1 bereits ein Verriegelungsmechanismus vorgeschlagen, bei dem das benachbarte Rahmenprofil des sich an den zu verriegelnden Faltflügel anschließenden Flügels ebenfalls einen Riegel aufweist, der über Mitnehmer am Verriegelungsbeschlag gleichzeitig betätigbar ist. Diese Konstruktion bietet zwar einen erhöhten Einbruchschutz, ist aber verhältnismäßig kompliziert.In order to take better protection into account, the EP 2 275 632 B1 a locking mechanism has already been proposed in which the adjacent frame profile of the sash adjoining the folding sash to be locked also has a latch which can be actuated simultaneously via drivers on the locking fitting. Although this construction offers increased protection against burglary, it is relatively complicated.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Faltanlage mit einer sicheren Verriegelung zu schaffen, die konstruktiv einfach und solide ist. Diese Aufgabe wird durch eine Faltanlage mit den Merkmalen des Anspruchs 1 gelöst.The invention is therefore based on the object of creating a folding system with a secure lock that is structurally simple and solid. This object is achieved by a folding system with the features of claim 1.

Durch das Vorsehen mindestens eines Verriegelungszapfens in der Funktion eines Verstärkungszapfens im Rahmenprofil desselben Faltflügels, in dem sich auch der Verriegelungszapfen befindet, können die beiden Zapfen hinsichtlich ihrer Bewegung parallel aber fest verbunden werden, so dass der Verstärkungszapfen mit dem Verriegelungszapfen mitbewegbar angeordnet ist. Es bedarf keiner Koppelung über den beweglichen Zwischenraum zweier Flügel hinweg. Die Verriegelung beider Zapfen kann weiterhin nur über ein Verriegelungsgetriebe erfolgen. Durch den zusätzlichen Verstärkungszapfen setzen die Verriegelungskräfte jedoch an mehreren Punkten an (Verriegelungszapfen und Verstärkungszapfen), dadurch wird die Belastung bzw. Kraft auf den einzelnen Zapfen zumindest halbiert. Bei Einbruchversuchen oder anstehenden Windlasten verteilt sich die Krafteinleitung in die Führungsschiene besser und verringert die Gefahr, dass sich die Führungsschiene oder die Zapfen verbiegen. Wenn benachbarte Faltflügel über Scharniere verbunden sind, erstreckt sich die verbesserte Verriegelungswirkung auch auf den zur Verriegelung benachbarten Faltflügel. Die erfindungsgemäße Verriegelung kann jedoch ebenfalls wandseitig oder bei Faltflügeln zum Einsatz kommen, die mit einem benachbarten Flügel nicht fest, insbesondere nicht über Scharniere verbunden sind.By providing at least one locking pin in the function of a reinforcing pin in the frame profile of the same folding sash in which the locking pin is also located, the two pins can be connected in parallel but firmly with regard to their movement, so that the reinforcing pin can be moved along with the locking pin. There is no need for coupling across the movable space between two wings. Both pins can still only be locked using a locking gear. However, due to the additional reinforcement pin, the locking forces are applied at several points (locking pin and reinforcement pin), which means that the load or force on the individual pins is at least halved. In the event of attempted break-ins or pending wind loads, the introduction of force into the guide rail is better distributed and reduces the risk of the guide rail or the pins bending. If adjacent folding wings are connected via hinges, the improved locking effect also extends to the folding wing adjacent to the locking. The lock according to the invention can, however, also be used on the wall side or with folding sashes that are not firmly connected to an adjacent sash, in particular not connected via hinges.

Neben der Sicherung gegen Einbrüche ist insbesondere ein sicheres Verschließen von Faltanlagen bei hohen Windlasten vorteilhaft. Dazu erweist es sich als positiv, den Verstärkungszapfen in einem ergänzenden Verstärkungsprofil des Rahmenprofils aufzunehmen, wodurch die Stabilität des Faltflügels gegen Verbiegen erhöht wird. Bei entsprechender Auslegung kann eine Durchbiegung der Faltflügel unter Windlast soweit herabgesetzt werden, dass keine Gefahr mehr besteht, dass Verriegelungs- und Verstärkungszapfen aus den Führungsschienen herausspringen. Auch lässt sich ein ergänzendes Verstärkungsprofil, insbesondere wenn dieses lösbar am bisherigen Rahmenprofilstück befestigt ist, problemlos nachrüsten oder nur im Bedarfsfall vorsehen. Es ist jedoch auch möglich, das Verstärkungsprofil einstückig mit dem die Verriegelungszapfen aufnehmenden Profilstück auszubilden.In addition to securing against break-ins, it is particularly advantageous to securely lock folding systems in the event of high wind loads. For this purpose, it has proven to be positive to accommodate the reinforcement pin in a supplementary reinforcement profile of the frame profile, as a result of which the stability of the folding sash against bending is increased. With an appropriate design, the folding sash can sag under Wind load can be reduced to such an extent that there is no longer any risk of locking and reinforcing pins jumping out of the guide rails. A supplementary reinforcement profile can also be retrofitted without any problems, in particular if it is detachably fastened to the previous frame profile piece, or only provided if necessary. However, it is also possible to form the reinforcement profile in one piece with the profile piece receiving the locking pin.

Eine Stabilitätsverbesserung lässt sich auch erreichen, indem das Rahmenprofil einen senkrecht verlaufenden, schwertartigen Vorsprung aufweist, der Durchbiegungen entgegenwirkt. Der Vorsprung hat bevorzugt eine leistenartige bzw. schwertartige Form mit einer Höhe, die vorzugsweise einen überwiegenden Teil der Höhe des senkrechten Rahmenprofils einnimmt. Die Breite des Vorsprungs ist demgegenüber eher gering, und seine Tiefe, d.h. seine Erstreckung senkrecht zur Faltflügelebene ist bevorzugt größer als seine Breite. Der Vorsprung kann einstückig mit dem Rahmenprofil ausgebildet oder mit diesem verbunden sein. Wenn dieser Vorsprung am Verstärkungsprofil vorgesehen wird, kann die Anzahl der benötigen Komponenten für verschiedene Ausführungsformen dennoch klein gehalten werden, da die erforderliche Stabilität fallweise durch die Wahl eines geeigneten Verstärkungsprofils, mit oder ohne Vorsprung eingestellt werden kann.An improvement in stability can also be achieved if the frame profile has a vertically extending, sword-like projection that counteracts deflection. The projection preferably has a strip-like or sword-like shape with a height that preferably occupies a predominant part of the height of the vertical frame profile. In contrast, the width of the projection is rather small, and its depth, i.e. its extent perpendicular to the plane of the folding wing, is preferably greater than its width. The projection can be formed in one piece with the frame profile or connected to it. If this projection is provided on the reinforcement profile, the number of components required for different embodiments can nevertheless be kept small, since the required stability can be adjusted on a case-by-case basis by choosing a suitable reinforcement profile, with or without a projection.

Auf konstruktiv einfache Weise, ohne die Ausgestaltung des Verriegelungsgetriebes verändern zu müssen, kann der Verstärkungszapfen über ein Adapterstück mit dem Verriegelungszapfen verbunden werden. Zur fallweise auch nachträglichen Montage kann es vorteilhaft sein, wenn das Adapterstück dazu eine Montageausnehmung aufweist, die den Zugriff durch Werkzeug zur Herstellung der Verbindung ermöglicht. Das Adapterstück kann dazu im Wesentlichen C- bzw. U-förmig ausgebildet sein.In a structurally simple manner, without having to change the design of the locking gear, the reinforcing pin can be connected to the locking pin via an adapter piece. For subsequent assembly in some cases, it can be advantageous if the adapter piece has a mounting recess for this purpose which allows access by tools to make the connection. For this purpose, the adapter piece can be essentially C-shaped or U-shaped.

Darüber hinaus kann das Adapterstück konstruktiv zur Führung der Bewegung des Verstärkungszapfens genutzt werden, wozu es von Vorteil ist, dass das Adapterstück eine Führungsfläche aufweist, die an einer Führungsgegenfläche des Verstärkungsprofils senkrecht verschiebbar anliegt. Eine entsprechende Ausgestaltung ist auch gegenüberliegend im Profilstück möglich.In addition, the adapter piece can be used constructively to guide the movement of the reinforcement pin, for which purpose it is advantageous that the adapter piece has a guide surface which rests vertically displaceably on a guide counter surface of the reinforcement profile. A corresponding configuration is also possible opposite in the profile piece.

Das C- bzw. U-förmige Adapterstück hat vorzugsweise zumindest zwei im Wesentlichen waagerechte Schenkel, die durch zumindest einen im Wesentlichen senkrechten Schenkel verbunden sind. In den im Wesentlichen waagerechten Schenkeln sind Koppelbereiche ausgebildet, an denen Kraftübertragungselemente, insbesondere Riegelstangen zur Kraftübertragung auf die Zapfen angreifen. Zwischen den im Wesentlichen horizontalen Schenkeln befindet sich eine Montageausnehmung, deren freie Höhe in vertikaler Richtung vorzugsweise größer als die Höhe in vertikaler Richtung der im Wesentlichen horizontalen Schenkel ist, insbesondere sogar als die Summe der Höhen der im Wesentlichen vertikalen Schenkel. Dieser Aufbau erleichtert die Montage und Wartung der Faltanlage. Konkret sollte die freie Höhe der Montageausnehmung mindestens der Länge zu verwendender Verbindungselemente entsprechen, z.B. von Schrauben inklusive der Schraubenköpfe, die die Koppelbereiche durchgreifen.The C- or U-shaped adapter piece preferably has at least two essentially horizontal legs which are connected by at least one essentially vertical leg. In the essentially horizontal legs, coupling areas are formed, on which force transmission elements, in particular locking rods, engage for force transmission to the pins. Between the essentially horizontal legs there is a mounting recess, the free height of which in the vertical direction is preferably greater than the height in the vertical direction of the essentially horizontal legs, in particular even than the sum of the heights of the essentially vertical legs. This structure facilitates the assembly and maintenance of the folding system. Specifically, the free height of the mounting recess should at least correspond to the length of the connecting elements to be used, for example screws including the screw heads that reach through the coupling areas.

Die Koppelbereiche des Adapterstücks sind zumindest teilweise als Ausnehmungen bzw. teilweise sogar als Durchgangsbohrungen ausgebildet und können sich von unten/oben vorzugsweise parallel durch das Adapterstück hindurcherstrecken. Zumindest eine der beiden Ausnehmungen ist insbesondere durch einen ersten der im Wesentlichen waagerechten Schenkel als Durchgangsbohrung ausgebildet. Die andere Ausnehmung in diesem Schenkel kann eine Sacklochbohrung sein. Im montierten Zustand der Faltanlage kann jede der beiden Ausnehmungen eine Riegelstange aufnehmen. Eine der Riegelstangen ist dabei mit dem Verriegelungszapfen, die andere der Riegelstangen mit dem Verstärkungszapfen verbunden. Eine dritte Ausnehmung ist bevorzugt als Durchgangsbohrung durch einen zweiten der im Wesentlichen waagerechten Schenkel ausgebildet. Im montierten Zustand der Faltanlage kann diese Bohrung eine Schubstange zur Einleitung von Kraft aufnehmen. Besonders bevorzugt ist am Verriegelungsgetriebe beidseitig je ein derart ausgebildetes Adapterstück angeordnet.The coupling areas of the adapter piece are at least partially designed as recesses or partially even as through bores and can extend through the adapter piece from below / above, preferably parallel. At least one of the two recesses is designed as a through-hole, in particular through a first of the essentially horizontal legs. The other recess in this leg can be a blind hole. In the assembled state of the folding system, each of the two recesses can accommodate a locking bar. One of the locking bars is connected to the locking pin, the other of the locking bars is connected to the reinforcing pin. A third recess is preferably designed as a through hole through a second of the essentially horizontal legs. In the assembled state of the folding system, this hole can accommodate a push rod for introducing force. Particularly preferably, an adapter piece designed in this way is arranged on both sides of the locking gear.

Die Übertragung der Verriegelungskräfte auf die Führungsschienen erfolgt besonders sicher aber materialschonend, wenn Verriegelungszapfen und Verstärkungszapfen hinsichtlich ihrer Berührpunkte mit der Führungsschiene voneinander beanstandet angeordnet sind. Der Abstand kann etwa dem Durchmesser der Zapfen entsprechen. Vorteilhaft ist es, wenn der Abstand zumindest so groß ist, wie die tragende Eindringtiefe der Zapfen in die Führungsschiene.The transmission of the locking forces to the guide rails is particularly secure but gentle on the material when the locking pins and reinforcing pins are spaced apart from one another with regard to their points of contact with the guide rail. The distance can correspond approximately to the diameter of the pin. It is advantageous if the distance is at least as great as the load-bearing penetration depth of the pin in the guide rail.

Die dargestellten Faltflügel 1 haben jeweils Glasscheiben 2, die in Rahmenprofilen 3,4 gehalten sind. Der in der Darstellung rechte Faltflügel 1 verfügt dabei über eine Verriegelung, die über einen Griff 5 betätigbar ist. Damit lassen sich ein Verriegelungszapfen 6 und ein Verstärkungszapfen 7 in die Führungsschiene 8 hineinbewegen, wodurch ein Verschwenken der Flügel verhindert wird. Der Verriegelungszapfen 6 ist in einem Profilstück 4' des Rahmenprofils 4 geführt, während der Verstärkungszapfen 7 in einem Verstärkungsprofil 4" des Rahmenprofils 4 aufgenommen ist.In Fig. 1 the lower area of two interconnected folding panels 1 is shown in the closed functional position of the lock. Above this there is a small pictogram-like representation of an exemplary folding system to illustrate the function. The folding leaves 1 shown each have glass panes 2 which are held in frame profiles 3, 4. The one on the right in the illustration The folding sash 1 has a lock which can be actuated via a handle 5. In this way, a locking pin 6 and a reinforcing pin 7 can be moved into the guide rail 8, thereby preventing the wings from pivoting. The locking pin 6 is guided in a profile piece 4 ′ of the frame profile 4, while the reinforcement pin 7 is received in a reinforcement profile 4 ″ of the frame profile 4.

Die Fig. 2 bis 5 veranschaulichen die Funktion und die Einzelkomponenten der erfindungsgemäßen Konstruktion. So sind in den Fig. 3 und 4 unter Weglassung des Griffs die Rahmenprofile 3,4 und die Führungsschiene 8 transparent (strichpunktiert) dargestellt, so dass der Blick auf ein innenliegendes Verriegelungsgetriebe 9 mit sich daran anschließenden Bauteilen freigegeben ist. Das Verriegelungsgetriebe 9 wirkt über Schubstangen 10 und sich daran anschließende Adapterstücke 11 auf mit diesen verbundene Riegelstangen 12, an deren Enden sich Verriegelungszapfen 6 und Verstärkungszapfen 7 befinden. Auch die oberen Riegelstangen 12 tragen bei dieser Ausführungsform Zapfen 6,7, die jedoch wegen der oben abgeschnittenen Darstellung hier nicht zu sehen sind. Selbstverständlich können die Riegelstangen 12 mit ihren Enden auch selbst die Zapfen 6,7 ausbilden und/oder auch einstückig in diese übergehen.The Figures 2 to 5 illustrate the function and the individual components of the construction according to the invention. So are in the Fig. 3 and 4th with the omission of the handle, the frame profiles 3, 4 and the guide rail 8 are shown transparently (dash-dotted), so that the view of an internal locking mechanism 9 with adjoining components is released. The locking gear 9 acts via push rods 10 and adapter pieces 11 connected to them on locking rods 12 connected to them, at the ends of which there are locking pins 6 and reinforcing pins 7. In this embodiment, the upper locking rods 12 also carry pins 6, 7, which, however, cannot be seen here because of the illustration cut off above. Of course, the ends of the locking rods 12 can also form the pins 6, 7 themselves and / or also merge into them in one piece.

In den Fig. 2 und 3 ist die Verriegelung in ihrer geschlossenen Funktionsstellung gezeigt, wobei die Zapfen 6,7 in die Führungsschiene 8 eintauchen und die Faltflügel so verriegeln. Fig. 4 hingegen zeigt die Verriegelung in ihrer geöffneten Position. Dazu wurden der dort nicht dargestellte Griff 5 um 180° nach oben verschwenkt und so über das Getriebe 9 die Adapterstücke 11 mit den angeschlossenen Riegelstangen 12 und den Zapfen 6,7 zum Verriegelungsgetriebe 9 hin verschoben. Die Zapfen 6,7 befinden sich nun außerhalb der Führungsschiene 8 und geben die Faltflügel 1 zur Öffnung frei. Um die Verriegelungskräfte in der Führungsschiene 8 zu verteilen, sind die Zapfen 6,7 um einen Abstand A voneinander beabstandet. Dieser bemisst sich bei der dargestellten Ausführungsform zwischen den Mittellängsachsen der Zapfen 6,7, da diese rund sind und in der Schiene 8 somit nur linienförmig berührend anliegen. Der Abstand A sollte zumindest der tragenden Eindringtiefe E der Zapfen 6,7 in der Schiene 8 entsprechen, bevorzugt aber größer, besonders bevorzugt sogar doppelt so groß sein.In the Fig. 2 and 3 the locking mechanism is shown in its closed functional position, with the pins 6, 7 dipping into the guide rail 8 and thus locking the folding sashes. Fig. 4 however, shows the lock in its open position. For this purpose, the handle 5, not shown there, was pivoted upwards by 180 ° and so via the gear 9, the adapter pieces 11 with the connected locking rods 12 and the pins 6, 7 are moved towards the locking gear 9. The pins 6, 7 are now outside the guide rail 8 and release the folding sash 1 for opening. In order to distribute the locking forces in the guide rail 8, the pins 6, 7 are spaced from one another by a distance A. In the embodiment shown, this is measured between the central longitudinal axes of the pegs 6, 7, since these are round and therefore only contact the rail 8 in a linear manner. The distance A should at least correspond to the load-bearing penetration depth E of the pins 6, 7 in the rail 8, but should preferably be larger, particularly preferably even twice as large.

Weitere Details der Konstruktion sind den Fig. 2 und 5 sowie der in Fig. 6 dargestellten Variante zu entnehmen. In zusammengebautem Zustand ist das Verriegelungsgetriebe 9 mit den Schubstangen 10 im Profilstück 4' des Rahmenprofils 4 angeordnet, während sich die Verstärkungszapfen 7 mit einem entsprechenden Teil der Adapterstücke 11 im Verstärkungsprofil 4" befinden. Im Übergang zwischen dem Profilstück 4' und dem Verstärkungsprofil 4" haben beide Teile 4',4" eine Ausnehmung 16 (siehe Fig. 2), durch die die Adapterstücke 11 hindurchtauchen. Die Ausnehmungen 16 sind so groß auszubilden, dass sie die Auf- und Abbewegung der Adapterstücke 11 bei einem Ver- und Entriegeln zulassen. Die Adapterstücke 11 haben Montageausnehmungen 11', die es ermöglichen, an den Adapterstücken 11 mit entsprechendem Werkzeug die angrenzenden Schubstangen 10 und Riegelstangen 12 zu befestigen. Die Adapterstücke 11 haben auf ihrer dem Verstärkungsprofil 4" zugewandten Seite Führungsflächen 11", die an einer Führungsgegenfläche 21 des Verstärkungsprofils 4" anliegen, wodurch die Auf- und Abbewegung der Adapterstücke 11 stabilisiert und geführt ist. Bei der dargestellten Ausführungsform sind in vorteilhafter Weise stabilitätserhöhend entsprechende Führungsflächen 11"' auch auf der gegenüberliegenden Seite vorgesehen, die an einer Führungsgegenfläche 21' des Profilstücks 4' anliegen.Further details of the construction are the Fig. 2 and 5 as well as the in Fig. 6 shown variant. In the assembled state, the locking gear 9 with the push rods 10 is arranged in the profile piece 4 'of the frame profile 4, while the reinforcement pins 7 with a corresponding part of the adapter pieces 11 are in the reinforcement profile 4 ". In the transition between the profile piece 4' and the reinforcement profile 4" both parts 4 ', 4 "have a recess 16 (see Fig. 2 ) through which the adapter pieces 11 dip. The recesses 16 are to be made so large that they allow the adapter pieces 11 to move up and down during locking and unlocking. The adapter pieces 11 have assembly recesses 11 'which make it possible to fasten the adjoining push rods 10 and locking rods 12 to the adapter pieces 11 with a suitable tool. The adapter pieces 11 have on their side facing the reinforcement profile 4 "guide surfaces 11" which are on a guide counter surface 21 of the reinforcement profile 4 ″, whereby the up and down movement of the adapter pieces 11 is stabilized and guided. In the embodiment shown, corresponding guide surfaces 11 ″ 'are advantageously provided on the opposite side to increase stability, which are on a guide counter surface 21' of the profile piece 4 '.

Während die Fig. 1 bis 5 eine Ausführungsform zeigen, bei der sich das Rahmenprofil 4 aus zwei mittels Schraubverbindungen 17 lösbar verbundenen Profilteilen, nämlich dem Profilstück 4' und dem Verstärkungsprofil 4" zusammensetzt, zeigt Fig. 6 eine alternative Ausführungsform mit einer einstückigen Ausführung des Rahmenprofils 4. In beiden Fällen jedoch ist das Rahmenprofil 4 über Scharnierbeschläge 18 mit dem Rahmenprofil 3 des benachbarten Faltflügels 1 verbunden, so dass die beiden Faltflügel 1 im fertig montierten Zustand der Faltanlage und bei geöffneter Position der Verriegelung gegeneinander verschwenkbar sind, jedoch verbunden bleiben.While the Figs. 1 to 5 show an embodiment in which the frame profile 4 is composed of two profile parts releasably connected by means of screw connections 17, namely the profile piece 4 ′ and the reinforcement profile 4 ″ Fig. 6 An alternative embodiment with a one-piece design of the frame profile 4. In both cases, however, the frame profile 4 is connected to the frame profile 3 of the adjacent folding sash 1 via hinge fittings 18, so that the two folding sashes 1 in the fully assembled state of the folding system and with the lock in the open position are pivotable against each other, but remain connected.

Die konstruktive Gestaltung der erfindungsgemäßen Faltanlage und insbesondere ihrer Verriegelung ist einfach, solide, wartungsarm und sicher.The structural design of the folding system according to the invention and in particular its locking is simple, solid, low-maintenance and safe.
