Description

Titel: Türbetätiger und Verfahren zur Herstellung Beschreibung Die vorliegende Erfindung betrifft einen Türbetätiger mit einem Gehäuse, in dem ein fluidisch und/oder federbelasteter Kolben in einem Kolbenraum verschiebbar angeordnet und geführt ist, wobei das Gehäuse stirnseitig durch ein Verschlusselement abgedichtet und verschlossen wird. Der Stand der Technik offenbart Türbetätiger, bei denen eine Verschlussschraube zum Einsatz kommt, die stirnseitig den Türbetätiger verschließt. Diese Verschlussschraube weist eine Nut auf, in der eine Dichtung zur Abdichtung des Kolbenraumes eingelegt wird, wobei die Verschlussschraube aufgrund eines angeordneten Gewindes in das Gehäuse des Türbetätigers eingeschraubt wird.  The present invention relates to a door operator with a housing in which a fluidically and / or spring-loaded piston is arranged and guided displaceably in a piston chamber, wherein the housing is sealed and closed at the end by a closure element. The prior art discloses door operators, in which a screw plug is used, the front side closes the door operator. This screw plug has a groove in which a seal for sealing the piston chamber is inserted, wherein the screw plug is screwed due to an arranged thread in the housing of the door operator.
Der Stand der Technik beinhaltet den Nachteil, dass an der Verschlussschraube eine Nut für die erforderliche Dichtung sowie ein Gewinde zum Einschrauben der Verschlussschraube in das Gehäuse des Türbetätigers angebracht werden müssen, wobei ein entsprechendes Gegengewinde am Gehäuse des Türbetätigers anzubringen ist, welches in der Herstellung teuer ist. The prior art has the disadvantage that on the screw plug a groove for the required seal and a thread for screwing the screw plug must be mounted in the housing of the door operator, with a corresponding mating thread is to be attached to the housing of the door operator, which is expensive to manufacture is.
Ein weiterer Nachteil der bekannten Türbetätiger besteht darin, dass bei der Montage des Türbetätigers der Arbeitsgang des Einschraubens der Verschlussschraube in das Gehäuse des Türbetätigers eine gewisse Zeit in Anspruch genommen werden muss, die in Bezug auf eine Jahresmenge von Türbetätigern erhebliche Montagekosten aufkommen lässt. Es ist daher die Aufgabe der vorliegenden Erfindung, ein Verschlusselement für ein Gehäuse eines Türbetätigers bereit zu stellen, welches einen Another disadvantage of the known door operator is that during the assembly of the door operator of the operation of screwing the screw plug into the housing of the door operator must be taken a certain amount of time, which costs considerable installation costs in relation to an annual amount of door operators. It is therefore an object of the present invention to provide a closure element for a housing of a door operator, which a
BESTÄTIGUNGSKOPIE einfachen Aufbau aufweist, kostengünstig herzustellen ist und auf einfache Weise dichtend zu montieren ist. CONFIRMATION COPY has simple structure, is inexpensive to manufacture and is easy to mount sealing.
Diese Aufgabe wird ausgehend von einem Türbetätiger gemäß dem Ober- begriff des Anspruches 1 in Verbindung mit den kennzeichnenden Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben. This object is achieved on the basis of a door operator according to the preamble of claim 1 in conjunction with the characterizing features. Advantageous developments of the invention are specified in the dependent claims.
Die Erfindung geht dabei von dem Gedanken aus, dass der Verschluss eines Türbetätiger nach der Montage der erforderlichen Bauteile durch einen Deckel erfolgt, der mit Hilfe eines Werkzeuges und einer Dichtung in eine leckagefreie Position montiert wird, bei der der Türbetätiger in seiner Funktion unbeeinträchtigt bleibt. Die Erfindung schließt die technische Lehre ein, dass ein Verschlusselement als gewölbter Deckel ausgebildet ist, der auf Grund plastischer Verformung das Gehäuse des Türbetätigers dichtend verschließt. The invention is based on the idea that the closure of a door operator after the assembly of the required components by a lid which is mounted by means of a tool and a seal in a leak-free position in which the door operator remains unaffected in its function. The invention includes the technical teaching that a closure element is designed as a domed lid, which sealingly seals the housing of the door operator due to plastic deformation.
Die erfinderische Ausführungsform besitzt den Vorteil, dass zum Ver- schluss des Gehäuses des Türbetätigers ein geometrisch einfach aufgebautes und somit kostengünstiges Bauteil verwendet werden kann. The inventive embodiment has the advantage that the closure of the housing of the door operator a geometrically simple and thus inexpensive component can be used.
Ebenso von Vorteil ist, dass das Gehäuse eine Öffnung mit einem Durchmesser aufweist, der eine zylinderförmige Fläche innerhalb des Gehäuses bildet. Zum Verschluss des Deckels sind einfach aufgebaute Werkzeuge benutzbar, wobei der Deckel am Gehäuse vertieft angeordnet ist und somit der Verschluss des Türbetätigers keine hervorstehende Abschnitte am Türbetätiger aufweist. Ebenfalls von Vorteil ist, dass der Kolbenraum, in dem der Kolben angeordnet ist, einen Durchmesser aufweist, der eine zylinderförmige Fläche innerhalb des Gehäuses bildet. Somit wird eine für den Türbetätiger erfor- derliche Geometrie zur Montage des Deckels verwendet, wobei die Funktion des Türbetätigers gewährleistet ist. It is also advantageous that the housing has an opening with a diameter which forms a cylindrical surface within the housing. For the closure of the lid are simple tools used, the lid is recessed on the housing and thus the closure of the door operator has no protruding portions on the door operator. It is also advantageous that the piston chamber, in which the piston is arranged, has a diameter which forms a cylindrical surface within the housing. Thus, a door operator required used derliche geometry for mounting the lid, the function of the door operator is ensured.
Weiterhin von Vorteil ist, dass am Übergang der Öffnung zum Kolbenraum eine umlaufende Nut für eine Dichtung angeordnet ist. Durch die angeordnete Nut ist eine erforderliche Dichtung auf einfache Weise zu montieren. It is also advantageous that a circumferential groove for a seal is arranged at the transition of the opening to the piston chamber. Through the groove arranged a required seal is easy to install.
Auch von Vorteil ist, dass der Durchmesser der Öffnung größer ist als der Durchmesser des Kolbenraumes. Der Deckel wird auf diese Weise zum Verschluss auf Position gehalten. It is also advantageous that the diameter of the opening is larger than the diameter of the piston chamber. The lid is held in this way to the closure in position.
Ebenso von Vorteil ist, dass am Übergang der Nut zum Kolbenraum eine umlaufende Fläche angeordnet ist, die zur Auflage des Deckels dient. Hierdurch kann der Deckel auf einfache Weise in die Öffnung eingelegt werden und liegt auf der umlaufenden Fläche an. It is also advantageous that a circumferential surface is arranged at the transition of the groove to the piston chamber, which serves to support the lid. In this way, the lid can be easily inserted into the opening and rests on the rotating surface.
Vorteilhaft ist, dass der Deckel auf der Fläche aufliegt und mit seinem Rand nach der plastischen Verformung zumindest teilweise in die Nut hineinragt und dabei die Dichtung verformt. Durch die plastische Verformung des Deckels erstreckt sich der größer werdende Außendurchmesser des Deckels in die Nut, wobei die Dichtung von dem Deckel dichtend verformt wird. It is advantageous that the lid rests on the surface and at least partially protrudes with its edge after the plastic deformation in the groove and thereby deforms the seal. Due to the plastic deformation of the lid, the larger outer diameter of the lid extends into the groove, wherein the seal is sealingly deformed by the lid.
Eine weitere bevorzugte Ausführungsform ist, dass der Deckel aus einem metallischen Werkstoff besteht. Bei einem im Betrieb befindlichen Türbetä- tiger herrschen Innendrücke, die von dem Deckel dauerhaft aufzufangen sind, um die leckagefreie Funktion des Türbetätigers sicher zu stellen, welches durch einen metallischen Werkstoff in Verbindung mit entsprechenden Eigenschaften und Abmaßen des Deckels gewährleistet ist. Weiterhin von Vorteil ist, dass die Dichtung unterschiedliche Formen, vorzugsweise ein O-Ring oder eine 4-Kanten Dichtung, aufweist. Somit kann eine kostengünstige Dichtung verwendet werden. Ebenso vorteilhaft ist, dass das Werkzeug zumindest teilweise in die Öffnung einführbar ist. Hierdurch wird der Verschluss versenkt am Gehäuse des Türbetätigers angeordnet, welches vorstehende Bauteile am Gehäuse des Türbetätigers verhindert und aus optischen Gründen zu bevorzugen ist. A further preferred embodiment is that the lid consists of a metallic material. In a door operator in operation, there are internal pressures which are to be permanently absorbed by the cover in order to ensure the leak-free operation of the door operator, which is ensured by a metallic material in conjunction with corresponding properties and dimensions of the lid. Another advantage is that the seal has different shapes, preferably an O-ring or a 4-edge seal. Thus, a low-cost seal can be used. It is also advantageous that the tool is at least partially insertable into the opening. As a result, the closure is sunk arranged on the housing of the door operator, which prevents protruding components on the housing of the door operator and is preferable for optical reasons.
Die Erfindung eines bevorzugten Ausführungsbeispiels wird anhand der nachstehenden Figuren und deren Beschreibungen näher dargestellt. The invention of a preferred embodiment will be further illustrated by the following figures and their descriptions.

Figur 6: eine Detail-Ansicht Z aus der Figur 5. In Figur 1 und 2 ist der Endbereich des Gehäuses 40 des Türbetätigers dargestellt. Das Gehäuse 40 kann als runder, ovaler oder rechteckiger Hohlzylinder ausgestaltet sein, in dem ein Kolben 20 fluidisch und/oder federbelastet verschiebbar angeordnet und geführt wird. Der Kolbenraum, in dem der Kolben 20 angeordnet ist, weist dabei einen Durchmesser B auf. Das Gehäuse 40 weist an einem Ende eine Öffnung 50 mit einem Durchmesser A auf. FIG. 6 shows a detail view Z from FIG. 5. In Figures 1 and 2, the end portion of the housing 40 of the door operator is shown. The housing 40 may be designed as a round, oval or rectangular hollow cylinder, in which a piston 20 is arranged and guided fluidly and / or spring-loaded. The piston chamber, in which the piston 20 is arranged, in this case has a diameter B. The housing 40 has an opening 50 with a diameter A at one end.
Am Ende des Gehäuses 40 ist im Bereich der Öffnung 50 eine umlaufen- de Nut 35 in die Wand des Gehäuses 40 eingearbeitet. In diese Nut 35 wird eine Dichtung 30 eingelegt. Der Durchmesser A der Öffnung 50 ist größer als der Durchmesser B des Kolbenraumes. Dadurch entsteht an der Nut stirnseitig zur Öffnung 50 hin eine ringförmige Fläche 45, die als Anschlag für einen Deckel 10 dient. At the end of the housing 40, a circumferential groove 35 is incorporated in the wall of the housing 40 in the region of the opening 50. In this groove 35, a seal 30 is inserted. The diameter A of the opening 50 is greater than the diameter B of the piston chamber. As a result, an annular surface 45, which serves as a stop for a cover 10, is produced on the groove at the end face toward the opening 50.
Zum Verschließen des Türschließergehäuses wird der Deckel 10 in die Öffnung 50 auf die Fläche 45 gelegt. Der Deckel 10 ist nach außen - also zur Öffnung 50 hin - konvex gewölbt. Der Deckel 10 wird durch ein Werkzeug 25 derart plastisch verformt, dass der Durchmesser des Deckels 10 sich vergrößert und dieser mit seinem Rand zumindest teilweise in die Nut 35 eintaucht. Dabei wird das Werkzeug 25 zu der gewölbten Fläche 15 des Deckels 10 geführt, bis er den Deckel 10 berührt. Als zusätzliche Abstützung des Deckels 10 wird der Kolben 20 derart positioniert, dass seine Stirnfläche im Bereich der ringförmigen Fläche 45 angeordnet ist. Dadurch wird der Verformungsvorgang unterstützt, in dem ein Durchrutschen des Deckels 10 - durch ein schnelles Umschlagen der Deckelwölbung - verhindert wird, wobei sich der Deckel 10 an den Kolben 20 anlegen kann. To close the door closer housing, the cover 10 is placed in the opening 50 on the surface 45. The cover 10 is outwardly convex - ie toward the opening 50 - convex. The lid 10 is plastically deformed by a tool 25 such that the diameter of the lid 10 is increased and this with its edge at least partially immersed in the groove 35. In this case, the tool 25 is guided to the curved surface 15 of the lid 10 until it touches the lid 10. As an additional support of the lid 10, the piston 20 is positioned such that its end face is arranged in the region of the annular surface 45. As a result, the deformation process is supported, in which slipping of the cover 10 - by a quick turning over the lid curvature - is prevented, with the lid 10 can invest in the piston 20.
In Figur 3 und 4 hat das Werkzeug 25 mit seiner Krafteinwirkung F auf die gewölbte Fläche 15 des Deckels 10 begonnen, wobei der Rand des De- ckels 10 sich schon teilweise in die Nut 35 erstreckt und dabei die Dichtung 30 verformt. In FIGS. 3 and 4, the tool 25 has begun to exert its force F on the curved surface 15 of the cover 10, the edge of the cover 10 10 already partly extends into the groove 35 and thereby deforms the seal 30.
In Figur 5 und 6 hat das Werkzeug 25 seine Endposition erreicht und den Deckel 10 plastisch verformt. Der Deckel 10 kann an dem Kolben 20 anliegen, wobei der Deckel 10 die Dichtung 30 derart verformt, dass die Dichtung 30 in Verbindung mit dem Deckel 10 eine leckagefreie Abdichtung vom Kolbenraum, dem Gehäuse 40 und der Öffnung 50 erzielt hat. Anschließend wird das Werkzeug 25 aus der Öffnung 50 herausgeführt und von dem Türschließer entfernt. In Figures 5 and 6, the tool 25 has reached its end position and the lid 10 plastically deformed. The lid 10 may abut the piston 20, the lid 10 deforming the seal 30 such that the seal 30 in conjunction with the lid 10 has achieved a leak-free seal from the piston chamber, the housing 40 and the opening 50. Subsequently, the tool 25 is led out of the opening 50 and removed from the door closer.
Bei dem Verschluss des Gehäuses 40 werden zunächst die erforderlichen Bauteile des Türbetätigers in das vorhandene Gehäuse 40 des Türbetäti- gers montiert, die für die Funktion des Türbetätigers notwendig sind. Schließlich erfolgt ein stirnseitiger Verschluss des Gehäuses 40. Das Gehäuse 40 besitzt im Abschnitt des Kolbenraumes eine Fläche 45, die durch die Nut 35 und dem Kolbenraum, in dem der Kolben 20 translatorisch bewegbar angeordnet ist, sowie der Öffnung 50, in die der Deckel 10 eingesetzt wird, gebildet wird. Dabei ist der Kolben 20 mit einem seiner Stirnseiten auf die Ebene der Fläche 45 positioniert und wird in dieser Position gehalten. Nachdem die Dichtung 30, vorzugsweise ein O-Ring, in die Nut 35 eingelegt ist, wird der gewölbte und somit vorgeformte Deckel 10 durch die Öffnung 50 des Gehäuses 40 bis zu der Ebene der Fläche 45 eingelegt. Der vorgeformte Deckel 10 besitzt eine gewölbte Fläche 15, wobei der Deckel 10 derart auf die Fläche 45 des Gehäuses 40 eingelegt wird, dass die gewölbte Fläche 15 in Richtung aus dem Gehäuse 40 zumindest teilweise herausragt. Die vorgeformte Kontur des Deckels 10 ist erforderlich, um den Deckel 10 durch die Öffnung 50 des Gehäuses 40 auf die Fläche 45 auflegen zu können, da der Außendurchmesser des gewölbten Deckels 10 kleiner ist als die Öffnung 50 des Gehäuses 40. Anschließend wird der gewölbten Fläche 15 ein Werkzeug 25 zugeführt, wo- bei das Werkzeug 25 eine Kraft F auf die gewölbte Fläche 15 ausübt, die dafür sorgt, dass der Deckel 10 plastisch verformt wird. Hierbei übt das Werkzeug 25 bis zu einer Endstellung eine Kraft F auf den Deckel 10 aus, wobei die Endstellung des Werkzeuges 25 erreicht ist, sobald der Deckel 10 sich plastisch verformt und die Dichtung 30 dichtend in der Nut 35 verformt hat, wobei sich der Deckel 10 an dem Kolben 20 abstützen kann. Das Werkzeug 25 besitzt einen Außendurchmesser, der derart ausgelegt ist, dass der Außendurchmesser durch die Öffnung 50 des Gehäuses 40 hindurchführbar ist. Dabei erstreckt sich der Deckel 10 zumindest teilweise in die Nut 35, da sich aufgrund der Krafteinwirkung des Werkzeuges 25 der Außendurchmesser des Deckels 10 vergrößert, wobei dieser Außendurchmesser größer ist als die Öffnung 50 des Gehäuses 40. Hierdurch hat sich der Deckel 10 derart plastisch verformt, wobei das Bestreben, in die vorgeformte Kontur zurück zu gelangen, verhindert wird. Die Vergrö- ßerung des Außendurchmessers des Deckels 10 in Verbindung mit der Tiefe der Nut 35 hat zur Folge, dass der Deckel 10 die in der Nut 35 befindliche Dichtung 30 verformt, wobei die Dichtung 30 und der Deckel 10 den Kolbenraum leckagefrei abdichten. In dieser Position ist der Deckel 10 unlösbar als Verschluss des Türbetäti- gers angeordnet, wobei ein kostengünstiger Deckel 10 verwendet wird und die Montage wenig Zeit in Anspruch nimmt. In the closure of the housing 40, the required components of the door operator are first mounted in the existing housing 40 of the Türbetäti- gers, which are necessary for the function of the door operator. Finally, there is a frontal closure of the housing 40. The housing 40 has in the portion of the piston chamber a surface 45 which is arranged translationally movable through the groove 35 and the piston chamber in which the piston 20 and the opening 50, in which the cover 10th is used, is formed. In this case, the piston 20 is positioned with one of its end faces on the plane of the surface 45 and is held in this position. After the seal 30, preferably an O-ring, is inserted into the groove 35, the curved and thus preformed cover 10 is inserted through the opening 50 of the housing 40 up to the plane of the surface 45. The preformed lid 10 has a curved surface 15, wherein the lid 10 is placed on the surface 45 of the housing 40 such that the curved surface 15 protrudes at least partially in the direction of the housing 40. The preformed contour of the lid 10 is required to place the lid 10 through the opening 50 of the housing 40 on the surface 45 can, since the outer diameter of the domed lid 10 is smaller than the opening 50 of the housing 40. Subsequently, the curved surface 15 a tool 25 is supplied, at the tool 25 exerts a force F on the curved surface 15, which ensures that the lid 10 is plastically deformed. In this case, the tool 25 exerts up to an end position a force F on the cover 10, wherein the end position of the tool 25 is reached when the lid 10 is plastically deformed and the seal 30 has sealingly deformed in the groove 35, wherein the lid 10 can be supported on the piston 20. The tool 25 has an outer diameter which is designed such that the outer diameter can be passed through the opening 50 of the housing 40. In this case, the cover 10 extends at least partially into the groove 35, as due to the force of the tool 25, the outer diameter of the lid 10 is increased, said outer diameter is greater than the opening 50 of the housing 40. As a result, the lid 10 has plastically deformed wherein the tendency to return to the preformed contour is prevented. The enlargement of the outer diameter of the cover 10 in conjunction with the depth of the groove 35 has the result that the cover 10 deforms the seal 30 located in the groove 35, wherein the seal 30 and the cover 10 seal the piston chamber without leakage. In this position, the lid 10 is permanently arranged as a closure of the Türbetäti- gers, wherein a cost-effective cover 10 is used and the assembly takes little time.
Diese Art des Verschlusses ist selbstverständlich auch anwendbar auf der Seite des Türbetätigers, an dem der Federraum des Türbetätigers angeordnet ist. Somit ist der Federraum eines Türbetätigers mit einem Deckel 10 in Verbindung mit einer innerhalb einer entsprechenden Nut 35 angeordneten Dichtung 30 leckagefrei abzudichten und zu verschließen. Bezugszeichenliste This type of closure is of course also applicable to the side of the door operator on which the spring chamber of the door operator is arranged. Thus, the spring chamber of a door operator with a lid 10 in conjunction with a disposed within a corresponding groove 35 seal 30 is leak-proof seal and close. LIST OF REFERENCE NUMBERS
