Abstract

A linkage for actuating swinging wings, such as doors (5) and the like, consists, as a rule, of a toggle-lever linkage (11). In order to avoid the risk of a possible shearing and pinching effect between the two levers (11a, b), particularly in their initial or closing position, provision is made for at least one of the two levers (11a, 11b) to be provided with an angular extension (23) projecting transversely away from the lever. This angular extension (23) can be dimensioned in such a way that, where a sliding linkage is concerned, whilst any pinching effect between the first and second lever (11a, 11b) or a rail (11c) is avoided, the spacing over the entire length of the levers or the rail is sufficiently large. <IMAGE>

Description

Die Erfindung betrifft ein Gestänge zum Antrieb von Drehflügeln wie Türen und dergleichen nach dem Oberbegriff des Anspruches 1.The invention relates to a linkage for driving rotating leaves such as doors and the like according to the preamble of claim 1.

Ein Drehflügelantrieb ist beispielsweise aus dem Prospektblatt "record-automatischer Drehflügelantrieb DFA 125" der Fa. AG für Türautomation bekannt geworden. Zwischen der eigentlichen, in einem Gehäuse untergebrachten Antriebseinheit und beispielsweise dem oberen Türrahmen wird herkömmlicherweise ein V-förmiges Gestänge, d. h. ein Kniehebel verwandt. Durch Verdrehen der Ausgangswelle der Antriebseinheit wird jeweils einer der beiden Hebel des Kniehebels in Rotation versetzt, der über die Gelenkverbindung den zweiten Hebel des Kniehebels und damit letztlich die zu betätigende Tür auf- und zuschwenkt.A swing door operator has become known, for example, from the brochure "record-automatic swing door operator DFA 125" from AG for door automation. Between the actual drive unit, which is accommodated in a housing, and, for example, the upper door frame, a V-shaped linkage, ie. H. a toggle lever used. By rotating the output shaft of the drive unit, one of the two levers of the toggle lever is set in rotation, which, via the articulated connection, pivots the second lever of the toggle lever and thus ultimately the door to be actuated.

Es handelt sich hierbei um ein sogenanntes Standardgestänge, welches in seiner Ruhelage in der Regel nach Art eines fast geschlossenen V's oberhalb der zu bewegenden Tür mehr oder weniger von der Türebene senkrecht vorsteht.It is a so-called standard linkage, which in its rest position is usually more like an almost closed V above the door to be moved or less protrudes vertically from the door plane.

Es sind allerdings auch sogenannte Parallelgestänge bekannt geworden, bei welchen die beiden zu dem Kniegelenk-Antrieb gehörenden Hebel eher in Parallellage zur Türebene ausgerichtet sind. Der Antrieb und die Funktion entsprechen aber ansonsten dem Standardgestänge.However, so-called parallel linkages have also become known, in which the two levers belonging to the knee joint drive are aligned more in parallel to the door plane. Otherwise, the drive and function correspond to the standard linkage.

In dem o. g. Prospektblatt ist darüber hinaus auch ein sogenanntes Gleitgestänge gezeigt. Hier wird eine an der Tür selbst angebrachte Gleitschiene verwandt, in welche der mit der Ausgangswelle der Antriebseinheit verbundene Hebel eingreift. Die an der Tür befestigte Gleitschiene dient insoweit als zweiter Hebel, wobei das freie Ende des in Rotation versetzbaren Hebels längs der Schiene bewegbar ist, also nach Art einer während des Öffnungs- und Schließvorganges der Tür nicht ortsfesten sondern relativ fortbewegbaren Gelenkverbindung.In the above Brochure sheet is also shown a so-called sliding linkage. Here a slide rail attached to the door is used, in which the lever connected to the output shaft of the drive unit engages. The slide rail attached to the door serves as a second lever, the free end of the rotatable lever being movable along the rail, that is, in the manner of an articulated connection that is not fixed but relatively movable during the opening and closing process of the door.

Die in diesem Zusammenhang bekannt gewordenen Gestänge werden seit Jahren und Jahrzehnten durchaus erfolgreich verwandt und eingesetzt. Allerdings bergen diese Gestänge auch gewisse Nachteile und Gefahren in sich.The rods that have become known in this context have been used and used successfully for years and decades. However, these linkages also have certain disadvantages and dangers.

Aufgabe der vorliegenden Erfindung ist es von daher ein Gestänge zum Antrieb von Drehflügeln wie Türen und dergleichen zu schaffen, welches gegenüber dem Stand der Technik bei insgesamt weiterhin einfachem Aufbau eine erhöhte Sicherheit aufweist.It is therefore an object of the present invention to provide a linkage for driving rotating leaves, such as doors and the like, which has increased safety compared to the prior art, while still being of a simple construction overall.

Die Aufgabe wird erfindungsgemäß entsprechend den im Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved according to the features specified in claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Die vorliegende Erfindung schafft auf verblüffende Art und Weise eine deutliche Verbesserung bezüglich des Sicherheitsstandards derartiger Gestänge. Denn die nach dem Stand der Technik bekannt gewordenen Gestänge weisen vor allem bei Verschwenkung in Verschlußlage Gefahren auf. Denn in Verschlußlage sind die über die beiden über ein Gelenk in Verbindung stehenden Hebel in eine V-Position gebracht, bei welcher der maximale Abstand zwischen den Hebeln oft nur weniger als 2 oder 3 cm beträgt. In Richtung des Gelenkes selbst nimmt dieser Abstand scherenartig ab, so daß beim Schließvorgang in ungünstigsten Fällen eine zwischen die beiden Hebeln eingebrachte Hand oder ein Finger gequetscht und abgeschert werden könnten.The present invention amazingly provides a significant improvement in security standards such linkage. This is because the linkages which have become known according to the prior art are particularly dangerous when pivoted in the locked position. Because in the locked position, the two levers, which are connected via a joint, are brought into a V position, in which the maximum distance between the levers is often only less than 2 or 3 cm. In the direction of the joint itself, this distance decreases like scissors, so that in the worst case a hand or a finger inserted between the two levers could be squeezed and sheared off during the closing process.

Demgegenüber schlägt die vorliegende Erfindung vor, zumindest an einem der Hebel einen in Querrichtung wegragenden zusätzlichen Hebelansatz vorzusehen, so daß zumindest einer der beiden Hebel im wesentlichen eine L-Form aufweist. Die Länge und Ausrichtung des Hebelansatzes kann derart sein, daß in Verschlußstellung die beiden Hebel z.B. eine Parallellage zueinander einnehmen, deren Abstand zueinander so ausreichend groß bemessen ist, daß vor allem dazwischen eingebrachte Finger oder die dazwischen eingebrachte Hand selbst nicht gequetscht werden können.In contrast, the present invention proposes to provide, at least on one of the levers, an additional lever shoulder projecting in the transverse direction, so that at least one of the two levers has an essentially L-shape. The length and orientation of the lever attachment can be such that in the closed position the two levers e.g. take a parallel position to each other, the distance between them is dimensioned sufficiently large that especially fingers inserted between them or the hand inserted between them cannot be squeezed.

Ein gattungsgemäßes Gestänge zum Antrieb von Drehflügeln ist grundsätzlich auch aus der DE-Z "BKS GmbH: Der Anschlag. In: Baubeschlag Magazin, 1957, Heft 3, Seiten 37 und 38" bekannt. Gemäß Abbildung 108 dieser Entgegenhaltung ist gezeigt, daß mindestens einer der beiden Hebel mit einem vom Hebel quer wegragenden Winkelansatz versehen ist, so daß zwischen dem ersten Hebel und dem zweiten Hebel ein über deren gesamte Länge verlaufender Abstand vorhanden ist. Durch die Schaffung einer Höhendifferenz zwischen den Befestigungspunkten des Schließers und des Gabelarmes mag zwar eine gewisse Verbesserung der Sicherheit gegenüber anderen herkömmlichen Lösungen erzielt werden. Eine stets ausreichende Sicherheit für alle nur denkbaren Fälle läßt sich jedoch mit einer derartigen Lösung nicht realisieren.A generic linkage for driving rotating blades is also known from DE-Z "BKS GmbH: The stop. In: Baubeschlag Magazin, 1957, Issue 3, pages 37 and 38". According to Figure 108 of this document, it is shown that at least one of the two levers is provided with an angular extension projecting transversely from the lever, so that there is a distance between the first lever and the second lever over their entire length. By creating a height difference between the fastening points of the closer and the fork arm, a certain improvement in safety compared to other conventional solutions may be achieved. However, adequate security for all conceivable cases can be achieved with such a system Do not implement the solution.

In einer besonders bevorzugten Ausführungsform der Erfindung ist das eine Ende des Hebels gabelförmig gestaltet und nimmt darin das andere Ende des zweiten Hebels auf. Dadurch können beide Hebel in einer Ebene liegend angeordnet werden. Unerwünschte zusätzliche Kippmomente bei der Kraftübertragung werden dadurch vermieden.In a particularly preferred embodiment of the invention, one end of the lever is fork-shaped and receives the other end of the second lever therein. As a result, both levers can be arranged lying in one plane. This prevents undesired additional tilting moments during power transmission.

In Figur 1 ist in ausschnittsweiser schematischer Darstellung ein Türrahmen 1 mit einer mittels einner Schwenkachse verschwenkbaren Drehflügel-Tür 5 gezeigt. Im Ausführungsbeispiel ist am oberen horizontalen Querholm des Türrahmens 1 das Gehäuse 7 eines Drehflügelantriebes 9 montiert. Über eine unten am Drehflügelantrieb 9 austretende Antriebsachse wird ein in Form eines Kniehebel gebildetes Gestänge 11 angetrieben, um darüber die Drehflügel-Tür 5 zu öffnen und zu schließen.FIG. 1 shows a partial schematic representation of a door frame 1 with a swing door 5 that can be pivoted by means of a pivot axis. In the exemplary embodiment, the housing 7 of a rotary leaf drive 9 is mounted on the upper horizontal cross member of the door frame 1. A linkage formed in the form of a toggle lever is driven via a drive axle emerging at the bottom of the swing door drive 9 in order to open and close the swing door 5.

Der genaue Aufbau und die Funktionsweise wird nachfolgend anhand der Figuren 2 und 3 erläutert.The exact structure and the mode of operation is explained below with reference to FIGS. 2 and 3.

In Figur 2 und 3 ist eine vertikal verlaufende Antriebsachse 13 gezeigt, die gleichzeitig die Ausgangswelle des Drehflügelantriebs 9 darstellt und bei entsprechendem in der Regel elektrischen Antrieb den in Figur 2 in seiner Ausgangs- und Verschlußstellung gezeigten ersten Hebel 11a längs der Kreisbahn 17 verschwenken kann.FIGS. 2 and 3 show a vertically running drive axis 13, which at the same time represents the output shaft of the rotary leaf drive 9 and can pivot the first lever 11a shown in FIG. 2 in its starting and closed position along the circular path 17 with a corresponding, usually electrical drive.

Der zweite Hebel 11b des Gestänges 11 ist an der Drehflügel-Tür 5 über ein Gelenk 19 angelenkt.The second lever 11b of the linkage 11 is articulated on the swing door 5 via a joint 19.

Beide Hebel 11a und 11b sind über eine Gelenkverbindung 21 verbunden.Both levers 11a and 11b are connected via an articulated connection 21.

Aus der Darstellung geht auch hervor, daß im gezeigten Ausführungsbeispiel der erste Hebel 11a benachbart zu der Gelenkverbindung 21 mit einem Hebel- oder Winkelansatz 23 versehen ist. Es ergibt sich dadurch eine L-Form, nachfolgend auch kurz als Golfschläger-Form bezeichnet.The illustration also shows that, in the exemplary embodiment shown, the first lever 11a is provided with a lever or angled shoulder 23 adjacent to the articulated connection 21. The result is an L-shape, hereinafter also referred to as a golf club shape.

Die Länge des Hebel-Winkelansatzes 23 wird bevorzugt so gewählt, daß er in der Regel mehr als 2 cm, vorzugsweise mehr als 2,5 cm, 3 cm, 3,5 cm, 4 cm, 4,5 cm, 5 cm usw. bis beispielsweise bei Bedarf auch 10 cm und sogar mehr betragen kann, je nach den Gegebenheiten und Anforderungen. In der Regel wird die Länge so gewählt, daß auch der rückwärtige Abstand zwischen der Antriebsachse 13 und dem Gelenk 19, also zwischen den beiden Anlenkpunkten der beiden Hebel 11a, 11b am Drehflügelantrieb 9 bzw. der Drehflügel-Tür 5 zumindest in etwa der Länge des Winkelansatzes 23 entspricht, so daß die beiden Hebel 11a oder 11b mit entsprechendem Abstand im wesentlichen parallel zueinander ausgerichtet sind und in der Regel in einem Winkel um etwa 90° von der Türebene vorstehen.The length of the lever-angle projection 23 is preferably chosen so that it is generally more than 2 cm, preferably more than 2.5 cm, 3 cm, 3.5 cm, 4 cm, 4.5 cm, 5 cm etc. up to 10 cm and even more if necessary, depending on the circumstances and requirements. In As a rule, the length is chosen so that the rear distance between the drive axis 13 and the hinge 19, that is, between the two articulation points of the two levers 11a, 11b on the rotary leaf drive 9 or the rotary leaf door 5 is at least approximately the length of the angle approach 23 corresponds, so that the two levers 11a or 11b are aligned at a corresponding distance substantially parallel to one another and generally protrude from the plane of the door at an angle of approximately 90 °.

Aus der in Figur 4 gezeigten teilweise im Schnitt wiedergegebenen Darstellung ist ersichtlich, daß der mit dem Winkelansatz 23 versehene Hebel 11a in einem gabelförmigen Ende 27 ausläuft, in welchem die Gelenkachse 21' gehalten ist, an welchem ein mit einer von der Gelenkachse 21' durchsetzten Querbohrung versehener und zum Hebel 11b gehörender Zapfen 12 verschwenkbar verankert ist. Durch diese Anordnung ist es möglich sicherzustellen, daß das Gestänge 11 und damit beide Hebel 11a und 11b in einer gemeinsamen Ebene senkrecht zu den Achsen 13, 19 sowie 21' liegen. Dadurch lassen sich beim Verschwenken unerwünschte Kippmomente vermeiden.From the illustration shown partially in section in FIG. 4, it can be seen that the lever 11a provided with the angular extension 23 ends in a fork-shaped end 27, in which the hinge axis 21 'is held, on which one is penetrated by the hinge axis 21' Cross bore provided and belonging to the lever 11b pin 12 is pivotally anchored. This arrangement makes it possible to ensure that the linkage 11 and thus both levers 11a and 11b lie in a common plane perpendicular to the axes 13, 19 and 21 '. This prevents undesired tilting moments when swiveling.

Zum Öffnen der Drehflügel-Tür 5 wird in nicht näher dargestellter Weise der Drehflügelantrieb 9 betätigt, so daß der erste Hebel 11a von der in Figur 2 bis in die in Figur 3 gezeigte Stellung verschwenkt wird, worüber unter entsprechender Verschwenkung des zweiten Hebels 11b die Tür in die in Figur 3 dargestellte Öffnungslage gebracht wird. Der Schließvorgang erfolgt umgekehrt, wobei durch die spezifische Gestaltung des Gestänges 11 selbst beim Einbringen von Fingern oder der Hand in den Abstandsraum zwischen den beiden Hebeln 11a und 11b die Finger bzw. die Hand nicht gequetscht werden können bzw. kann, da der Abstand ausreichend groß bemessen ist.To open the swing door 5, the swing drive 9 is actuated in a manner not shown, so that the first lever 11a is pivoted from the position shown in FIG. 2 to the position shown in FIG. 3, via which the door is pivoted accordingly is brought into the open position shown in Figure 3. The closing process takes place in reverse, whereby the fingers or the hand cannot or cannot be squeezed due to the specific design of the linkage 11 even when fingers or hand are inserted into the space between the two levers 11a and 11b, since the distance is sufficiently large is measured.

Abweichend vom gezeigten Ausführungsbeispiel könnte natürlich auch der andere Hebel 11b mit dem Winkelansatz 23 oder beide Hebel mit einem entsprechenden Winkelansatz versehen sein. Das kabelförmige Ende 27 könnte abweichend von dem gezeigten Ausführungsbeispiel am anderen Hebel vorgesehen sein.Deviating from the embodiment shown could of course the other lever 11b can also be provided with the angle extension 23 or both levers with a corresponding angle extension. In a departure from the exemplary embodiment shown, the cable-shaped end 27 could be provided on the other lever.

Grundsätzlich ist es auch möglich, beide Hebel um die Dicke des jeweiligen Hebels in Gelenkachsen-Richtung 21' versetzt aneinander anzulenken, wobei dann jedenfalls geringe Kippmomente auftreten können.In principle, it is also possible to link both levers to one another offset by the thickness of the respective lever in the joint axis direction 21 ', in which case, in any case, small tilting moments can occur.

Die Figuren 5 und 6 zeigen ein Beispiel, bei dem das Gestänge 11 nach Art eines Parallelgestänges dargestellt ist.Figures 5 and 6 show an example in which the linkage 11 is shown in the manner of a parallel linkage.

Von "Parallelgestänge" wird dann gesprochen, wenn der eine Hebel 11a etwa in Parallelrichtung zur Ebene der Drehflügel-Tür 5 ausgerichtet ist. Der zweite mit den ersten über die Gelenkverbindung 21 verbundene Hebel 11b greift dann an einem Drehflügel-Ansatz 5' an, der als feststehende kurze Säule sich z. B. etwa rechtwinklig von der Ebene der Drehflügel-Tür 5 weg erstreckt.The term "parallel linkage" is used when one lever 11a is aligned approximately in the direction parallel to the level of the swing door 5. The second lever 11b, which is connected to the first via the articulated connection 21, then engages with a rotary wing attachment 5 ', which, as a fixed short column, is arranged e.g. B. extends approximately at right angles from the plane of the swing door 5 away.

Bei Anwendung der Erfindung sind auch hier in der Schließstellung die beiden Hebel 11a und 11b in einem ausreichend großen Abstand zueinander verlaufend ausgerichtet, so daß auch hier keine Quetschungen entstehen können. Der Abstand kann gegebenenfalls auch so gewählt werden, daß in Schließstellung der Abstand zwischen dem über das Gehäuse 7 etwa in Parallellage nach vorne hin überstehenden zweiten Hebel 11b in ausreichendem Abstand von dem eigentlichen Gehäuse 7 zu liegen kommt, so daß bei dieser Ausführungsform auch keine Quetschung zwischen diesem zweiten Hebel 11b und der entsprechenden Gehäusewandung des Gehäuses 7 entstehen können.When using the invention, the two levers 11a and 11b are also aligned in the closed position at a sufficiently large distance from one another so that no bruises can occur here either. The distance can optionally also be chosen so that in the closed position the distance between the second lever 11b projecting beyond the housing 7 approximately in parallel position comes to lie at a sufficient distance from the actual housing 7, so that in this embodiment there is also no pinching can arise between this second lever 11b and the corresponding housing wall of the housing 7.

Das gleiche gilt grundsätzlich auch für das in den Figuren 7 und 8 dargestellte Beispiel unter Verwendung eines sogenannten Gleitgestänges. Hier greift an der Stelle, an der bei den anderen Ausführungsbeispielen die Gelenkachse 21' vorgesehen ist, ein entsprechender Gelenkbolzen 21'' in eine am Drehflügel 5 angebrachte Schiene 11c ein. Beim Öffnen und Schließen wird dieser Gelenkbolzen 21'' in der Schiene 11c verschoben. Dieser Gelenkbolzen 21'' kann insoweit auch als beim Öffnen und Schließen längs der Drehflügel-Tür 5 verfahrebare Gelenkverbindung zwischen dem ersten Hebel 11a und der im Sinne eines zweiten Hebels 11b wirkenden Schiene 11c verstanden werden. Auch bei dieser Ausführungsform kann der Hebel 11a neben seinem einen Winkelansatz 23 noch einem weiteren im Bereich der Antriebsachse 13 des Drehflügelantriebs 6 weiteren, sich in gleiche Seitenrichtung erstreckenden Winkelansatzes versehen sein, so daß hier ebenfalls keine Quetschung zwischen dem Hebel 11a und der Schiene 11c bzw. dem Gehäuse 7 des Drehflügelantriebes 9 eintreten kann. In diesem Falle könnten die Winkelansätze gleichgeformt sein, so daß sich der zwischen den Winkelansätzen verlaufende Abschnitt des Hebels 11a beispielsweise parallel zu einer zwischen seinen beiden gegenüberliegenden Anlenkpunkten verlaufenden Geraden ausgerichtet ist.The same basically applies to that in the figures 7 and 8 shown example using a so-called sliding linkage. Here, at the point at which the hinge axis 21 ′ is provided in the other exemplary embodiments, a corresponding hinge pin 21 ″ engages in a rail 11c attached to the rotating wing 5. When opening and closing, this hinge pin 21 ″ is displaced in the rail 11c. In this respect, this hinge pin 21 ″ can also be understood as a hinge connection between the first lever 11a and the rail 11c acting in the sense of a second lever 11b that can be moved along the swing door 5 when opening and closing. In this embodiment as well, the lever 11a can be provided, in addition to its one angle shoulder 23, another one in the area of the drive axis 13 of the rotary leaf drive 6, another angle shoulder extending in the same lateral direction, so that there is also no crushing between the lever 11a and the rail 11c or can enter the housing 7 of the rotary leaf drive 9. In this case, the angle lugs could be of the same shape, so that the section of the lever 11a running between the angle lugs is aligned, for example, parallel to a straight line running between its two opposite articulation points.
