Description

Die Erfindung betrifft einen Antrieb für einen Flügel einer Tür oder eines Fensters nach dem Oberbegriff des Anspruchs 1 und des Anspruchs 16.The invention relates to a drive for a wing of a door or a window according to the preamble of claim 1 and claim 16.

Aus der CH 281 690 ist ein Türschließer bekannt, welcher ein mit einer Flüssigkeit gefülltes Gehäuse aufweist. Das Gehäuse kann dabei aus einem öldichten Kunststoff bestehen und ist über ein schwalbenschwanzförmiges Befestigungsteil an einer an der Tür zu befestigenden Montageplatte verschiebbar und über Schrauben feststellbar geführt.From the CH 281 690 For example, a door closer is known which has a housing filled with a liquid. The housing may consist of an oil-tight plastic and is guided via a dovetail-shaped fastening part on a mounting plate to be fastened to the door displaceable and lockable by screws.

Bei dieser Konstruktion ist es nachteilig, dass das Kunststoffgehäuse hohe Wandstärken aufweist, um die am und im Türschließer auftretenden Kräfte abstützen zu können. Dadurch wird eine maßhaltige Anfertigung mit nicht spanabhebenden Verfahren erschwert, da Kunststoffe beispielsweise bei einer Anfertigung durch Spritzgießen beim Erkalten schwinden.In this construction, it is disadvantageous that the plastic housing has high wall thicknesses in order to support the forces occurring at and in the door closer can. As a result, a dimensionally accurate production is made more difficult with non-cutting methods, since plastics, for example, shrink when they are manufactured by injection molding on cooling.

Nachteilig ist es auch, dass Kunststoffe bei einer andauernden Beaufschlagung mit einer Kraft wegfließen können, wodurch sich die Gehäusemaße verändern.It is also disadvantageous that plastics can flow away with a force in the event of continuous application, as a result of which the dimensions of the housing change.

Bei einer Anordnung des Türschließers an einer Brandschutztüre würde das Kunststoffgehäuse des Türschließers im Brandfall durch die Hitzeeinwirkung schmelzen und der Türschließer könnte die Tür nicht mehr zuhalten.In an arrangement of the door closer to a fire door, the plastic housing of the door closer would melt in case of fire due to the effect of heat and the door closer could not hold the door.

Aus der DE 298 22 099 ist ein Türschließer bekannt mit einer Hubkurvenscheibe, die mit einer aus einem mit einem Dämpfungsmedium gefüllten Gehäuse austretenden Antriebswelle verbunden ist. Die Hubkurvenscheibe liegt in Achsrichtung gesehen auf jeder Seite an einer Andruckrolle an und steht mit einem mit einer Schließerfeder beaufschlagten Kolben in Wirkverbindung. Der Kolben und das Gehäuse bestehen aus einem öldichten Kunststoff, wobei der Kolben eine Buchse oder einen Kolbenring aus einem anderen Material aufweist. Die den Kolben umschließende Bohrung kann ebenfalls eine Buchse aus einem anderen Material aufweisen.From the DE 298 22 099 a door closer is known with a Hubkurvenscheibe which is connected to an emerging from a filled with a damping medium housing drive shaft. The Hubkurvenscheibe is seen in the axial direction on each side of a pinch roller and is in operative engagement with a piston acted upon by a closing spring. The piston and the housing are made of an oil-tight plastic, wherein the piston is a socket or having a piston ring of a different material. The piston enclosing bore may also have a bush made of a different material.

Nachteilig ist, dass Eigenschaften von Kunststoffen, wie deren Gleiteigenschaften, nicht genutzt werden können, da den Kolben zur Erhöhung der Lebensdauer eine Buchse oder ein Kolbenring aus einem anderen Material als Kunststoff umschließt, und der Kolbenaufnahmeraum ebenfalls aus einem anderen Material besteht. Durch die großen Materialstärken des Kunststoffs beim Kolben und beim Gehäuse ergeben sich große Schwindmaße, welche sich ungünstig auf die Maßgenauigkeit und damit auf die Passgenauigkeit von Kolben und Gehäuse auswirken.The disadvantage is that properties of plastics, such as their sliding properties, can not be used because the piston to increase the life of a bush or a piston ring of a material other than plastic encloses, and the piston receiving space is also made of a different material. Due to the large material thicknesses of the plastic in the piston and the housing large shrinkage, which adversely affect the dimensional accuracy and thus the accuracy of fit of the piston and housing.

Bei der Anordnung des Türschließers an einer Brandschutztüre besteht weiterhin der Nachteil, dass die mechanische Befestigung im Kunststoff des Türschließers durch die Hitzeentwicklung zerstört werden kann und eine Zuhaltung der Tür durch den Türschließer dann nicht mehr gegeben ist.In the arrangement of the door closer to a fire door continues to have the disadvantage that the mechanical fastening in the plastic of the door closer can be destroyed by the heat and a guard locking of the door by the door closer is then no longer given.

Die WO 95/20090 A zeigt einen Türschließer mit einem in einem Türschließergehäuse geführten und über ein Schließgetriebe mit einer drehbaren Schließerwelle beim Öffnen des zugeordneten Türflügels gegen eine Rückstellkraft verschiebbaren Schließkolben. Die Schließerwelle ist mit einer zwischen dem Türflügel und dem feststehenden Türrahmenbereich angeordneten Betätigungseinrichtung zur Kraftübertragung zwischen dem Türflügel und dem Türrahmenbereich verbunden sowie mit einem in dem Türschließergehäuse mit dem Schließkolben gleichsinnig verschobenen Dämpfungskolben, welcher aus Kunststoff besteht, wobei ein nicht formgebender Verzahnungseinsatz aus Metall zwischen dem Schließ- und dem Dämpfungskolben vorgesehen ist.The WO 95/20090 A shows a door closer with a guided in a door closer housing and a closing mechanism with a rotatable closer shaft when opening the associated door leaf against a restoring force sliding lock piston. The closer shaft is connected to a arranged between the door and the fixed door frame actuator for power transmission between the door leaf and the door frame and a in the door closer housing with the closing piston in the same direction shifted damping piston, which consists of plastic, wherein a non-forming toothing insert made of metal between the Closing and the damping piston is provided.

Aus der DE 200 10 423 U1 ist ein Türschließer bekannt, mit einem Türschließergehäuse sowie einer darin geführten und mittels eines Türschließergetriebes verschiebbaren Kolbenanordnung, welche einen Schließkolben, einen davon in Verschieberichtung beabstandeten Dämpfungskolben sowie ein zwischen dem Schließ- und dem Dämpfungskolben angeordnetes Kolbenzwischenstück mit einem Getriebeelement des Türschließergetriebes und einem Trägerteil hierfür aufweist. Der Schließ- und der Dämpfungskolben ist aus Kunststoff gefertigt und das nicht formgebende, als Verzahnungseinsatz ausgebildete Kolbenzwischenstück ist aus Metall gefertigt und endseitig in den Schließ- und den Dämpfungskolben eingebettet.From the DE 200 10 423 U1 a door closer is known, with a door closer housing and a guided therein and displaceable by means of a door closer gear Piston assembly, which has a closing piston, one of which in the direction of displacement spaced damping piston and arranged between the closing and the damping piston piston intermediate piece with a transmission element of the door closer transmission and a support member for this purpose. The closing and the damping piston is made of plastic and the non-forming, designed as a toothed insert piston intermediate piece is made of metal and embedded in the end closing and the damping piston.

Der Erfindung liegt die Aufgabe zugrunde, einen kostengünstigen Antrieb für den Flügel einer Tür oder eines Fensters unter Verwendung von Kunststoff auszubilden, mit einem Gehäuse und/oder einem Kolben, welche formbeständig und stabil sind.The invention has for its object to provide a cost-effective drive for the wing of a door or a window using plastic, with a housing and / or a piston, which are dimensionally stable and stable.

Die Aufgabe wird durch die Merkmale des Anspruchs 1 und des Anspruchs 16 gelöst.The object is solved by the features of claim 1 and claim 16.

Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous embodiments of the invention.

Ein erfindungsgemäßer Antrieb kann als automatischer Antrieb für Türen oder Fenster ausgebildet sein. Der Antrieb kann auch ein manueller Fensterantrieb oder ein Boden- oder Obentürschließer sein.An inventive drive can be designed as an automatic drive for doors or windows. The drive can also be a manual window operator or a floor or overhead door closer.

Beispielsweise sind dabei Obentürschließer über ein Gestänge mit dem Flügel der dem Türschließer zugeordneten Tür verbunden. Dieses Gestänge überträgt die Drehbewegung des Flügels auf eine Welle im Türschließer, welche beispielsweise über eine Verzahnung oder eine Hubkurvenscheibe einen mit einer Feder beaufschlagten Kolben verschiebt. Diese Verschiebebewegung findet innerhalb einer im Gehäuse befindlichen Hydraulikflüssigkeit statt, wobei die Hydraulikflüssigkeit von einer Seite des Kolbens auf die andere Seite durch Überströmkanäle und Ventile überströmen kann. In den Überströmkanälen sind üblicherweise Drosselventile angeordnet, womit das Verhalten des Türschließers eingestellt werden kann. Durch das Öffnen des Flügels wird der Kolben im Türschließer derart verschoben, dass die Feder gespannt wird. Durch ein Entspannen der Feder wird der Kolben wieder zurück verschoben und die Welle zurückgedreht, wodurch der Flügel über das Gestänge in seine Geschlossenlage geführt wird. Die auftretenden Kräfte müssen dabei vom Gehäuse und vom Kolben abgestützt werden.For example, overhead door closers are connected via a linkage to the wing of the door closer associated door. This linkage transmits the rotational movement of the wing to a shaft in the door closer, which shifts, for example via a toothing or a Hubkurvenscheibe a acted upon by a spring piston. This displacement movement takes place within a hydraulic fluid in the housing, wherein the hydraulic fluid can flow from one side of the piston to the other side by overflow and valves. Throttle valves are usually arranged in the overflow channels, with which the behavior of the door closer can be adjusted. Opening the sash moves the piston in the door closer so that the spring is tensioned. By relaxing the spring, the piston is moved back and the shaft is rotated back, whereby the wing is guided over the linkage in its closed position. The forces occurring must be supported by the housing and the piston.

Um die auf einen Antrieb mit einem unter Verwendung von Kunststoff ausgebildeten Gehäuse einwirkenden Kräfte aufnehmen zu können und die günstigen Eigenschaften des Kunststoffes nutzen zu können, wie etwa die Reibeigenschaften, wird ein Einlegeteil verwendet, welches zumindest abschnittsweise mit Kunststoff ummantelt wird, beispielsweise durch ein Spritzgussverfahren. Das Einlegeteil ist so ausgeformt, dass es alle erforderlichen Bereiche des Antriebsgehäuses versteift. Dabei ist im Bereich der Schließerwelle beidseitig ein Dom ausgebildet, welcher die Lagerung der Welle abstützen kann. Auf der dem Kolben gegenüberliegenden Seite der Feder sind am Einlegeteil umgebogene Fortsätze vorgesehen, welche die Federkraft der gespannten Feder abstützen können. Prägungen oder Sicken können das Einlegeteil weiter versteifen. Am Einlegeteil ist es außerdem vorgesehen, dass Befestigungslaschen ausgebildet sind, welche es erlauben, den Antrieb an der Tür oder in einem Bodengehäuse zu befestigen. Dabei können die Befestigungslaschen mit Kunststoff umspritzt sein oder frei gehalten werden. Vorteilhaft ist es auch, dass zur Befestigung beispielsweise Gewinde im Einlegeteil vorhanden sein können, welche eine höhere Festigkeit als Gewinde im Kunststoff aufweisen. Erfindungsgemäss ist das Einlegeteil mit Aussparungen versehen, welche ein Umfließen mit Kunststoff begünstigen.In order to absorb the forces acting on a drive with a trained using plastic housing forces and to be able to use the favorable properties of the plastic, such as the frictional properties, an insert is used, which is at least partially coated with plastic, for example by an injection molding process , The insert is shaped to stiffen all required areas of the drive housing. In this case, a dome is formed on both sides in the region of the closer shaft, which can support the bearing of the shaft. On the side opposite the piston of the spring bent projections are provided on the insert, which can support the spring force of the tensioned spring. Embossing or beading can further stiffen the insert. At the insert it is also provided that fastening tabs are formed, which allow to secure the drive to the door or in a bottom housing. The attachment tabs can be encapsulated with plastic or kept free. It is also advantageous that, for example, threads can be present in the insert for attachment, which has a higher strength than threads in the insert Plastic have. According to the invention the insert is provided with recesses, which favor a flow around plastic.

Der Kolben des Antriebs wird ebenfalls unter Verwendung eines Einlegeteils hergestellt, wodurch ein der Gehäuseform angepasster Kolben ausgebildet werden kann. Im Einlegeteil kann die Verzahnung für die Schließerwelle mit ausgebildet oder in das Einlegeteil des Kolbens eingesetzt und daran festgelegt sein. Ebenfalls können Aufnahmen für Ventile vorgesehen sein. Mögliche Verrippungen und Aussparungen können das Aufbringen von Kunststoff begünstigen und die Festigkeit des Einlegeteils erhöhen.The piston of the drive is also manufactured using an insert, whereby a housing adapted piston can be formed. In the insert part, the teeth for the closer shaft can be formed with or inserted into the insert part of the piston and fixed thereto. Also, recordings may be provided for valves. Possible ribbing and recesses may favor the application of plastic and increase the strength of the insert.

Durch die Verwendung eines Einlegeteils für den Kolben und das Gehäuse kann die Materialstärke des Kunststoffs klein gehalten werden, ohne die Vorteile des Kunststoffs zu verlieren. Die Gehäusemaße können damit ebenfalls besonders klein gehalten werden, wobei unterschiedliche Gehäuseformen, insbesondere im Kolbenraum ausgebildet werden können, die eine geringe Baugröße des Türschließers erlauben. Dabei kann der Kolbenraum abweichend von der üblichen runden Form rechteckig oder mehreckig ausgebildet sein, wodurch auch eine Verdrehsicherheit des Kolbens erreicht wird. Die Kanten des Kolbens können dabei gerundet werden.By using an insert for the piston and the housing, the material thickness of the plastic can be kept small without losing the advantages of the plastic. The housing dimensions can thus also be kept very small, with different housing shapes, in particular in the piston chamber can be formed, which allow a small size of the door closer. In this case, the piston chamber deviating from the usual round shape may be rectangular or polygonal, whereby a rotation of the piston is achieved. The edges of the piston can be rounded.

Bei hohen Festigkeitseigenschaften und hoher Formstabilität können die Eigenschaften des Kunststoffs genutzt werden, und es ist eine kostengünstige Fertigung ohne aufwändige mechanische Bearbeitung möglich.With high strength properties and high dimensional stability, the properties of the plastic can be used, and it is a cost-effective production without complex mechanical processing possible.

Vorteilhaft ist es auch, dass bei einer Verwendung an Brandschutztüren ein Ablösen des Antriebs vom Flügel verhindert wird, wie es hingegen bei einer ausschließlichen Befestigung in Kunststoff der Fall sein könnte.It is also advantageous that when used on fire doors a detachment of the drive from the wing is prevented, as it could be the case with an exclusive attachment in plastic.

Des Weiteren wird dabei der Flügel durch den Antrieb in Geschlossenlage gehalten, auch wenn der Kunststoff des Gehäuses abschmilzt, da sich die Feder an den umgebogenen Fortsätzen des Einlegeteils abstützen kann.Furthermore, while the wing is held by the drive in the closed position, even if the plastic of the housing melts, since the spring can be supported on the bent extensions of the insert.

Das Einlegeteil kann aus Metall als Stanz-Biegeteil ausgebildet sein, wodurch eine günstige Fertigung erzielt wird. Es kann aber auch mit anderen Fertigungsverfahren, wie Innen-Hochdruck-Umformverfahren, hergestellt werden, wodurch nahtlose Einlegeteile möglich sind. Es ist auch denkbar, andere Materialien einzusetzen, welche den jeweiligen Anforderungen genügen, wie etwa andere Kunststoffe, wenn auf die Vorteile des Verhaltens im Brandfall verzichtet werden kann. Vorteilhaft ist dabei, dass bei aus Kunststoff angefertigten Einlegeteilen in der Form sehr komplexe Ausbildungen kostengünstig herstellbar sind.The insert may be formed of metal as a stamped and bent part, whereby a favorable production is achieved. However, it can also be produced with other manufacturing processes, such as internal high-pressure forming, whereby seamless inserts are possible. It is also conceivable to use other materials which meet the respective requirements, such as other plastics, if the advantages of the behavior in case of fire can be dispensed with. It is advantageous that in case of plastic inserts made in the form of very complex designs can be produced inexpensively.

Das Stanz-Biegeteil kann, nachdem seine endgültige Form gebildet wurde, durch Umbiegen von Verschlusslaschen, durch Nieten, Schrauben oder aber auch durch Löten oder Schweißen zusammengefügt werden.
