Description

Die Erfindung betrifft einen Türschließer nach dem Oberbegriff des Patentanspruches 1, bei dem eine Hubkurvenscheibe vorhanden ist, die mit einer aus einem mit einem Dämpfungsmedium gefüllten Gehäuse austretenden Abtriebswelle kraft- und formschlüssig verbunden ist, wobei die Hubkurvenscheibe in Achsrichtung auf den Türschließer gesehen auf jeder Seite an je einer Andruckrolle anliegt und andererseits mit einem mit einer Schließfeder beaufschlagten Federkolben und andererseits mit einem Dämpfungskolben in Wirkverbindung steht, wobei der Kolben und das Gehäuse aus einem öldichten Kunststoff bestehen.The invention relates to a door closer according to the preamble of claim 1, in which a Hubkurvenscheibe is present, which is non-positively and positively connected to a discharged from a filled with a damping medium housing output shaft, the Hubkurvenscheibe seen in the axial direction of the door closer on each side abutting on a respective pinch roller and on the other hand is in operative connection with a spring loaded with a closing spring and on the other hand with a damping piston, wherein the piston and the housing are made of an oil-tight plastic.

Ein gattungsbildender Türschließer ist aus der Schweizer Patentschrift 281 690 bekannt geworden. Der dort beschriebene Türschließer ist für DIN links und DIN rechts angeschlagene Türen verwendbar, wobei eine vorhandene Abtriebswelle mit einer symmetrisch ausgebildeten Nockenscheibe ausgestattet ist, die mit dem Kolben und damit mit der Schließfeder in Kontakt steht. Sowohl das Gehäuse als auch der Kolben sind aus einem öldichten Kunststoff angefertigt.A generic door closer has become known from Swiss patent specification 281 690. The door closer described therein is suitable for DIN left and DIN right hinged doors, with an existing output shaft is equipped with a symmetrically shaped cam, which is in contact with the piston and thus with the closing spring. Both the housing and the piston are made of an oil-tight plastic.

Einen weiteren Türschließer zeigt die GB 2 292 182 A, wo ein Türschlie-ßer beschrieben wird, der eine in einem Kolben vorhandene Innenverzahnung wiedergibt. Hier sind die Verzahnung und der Kolben als getrennte Bauteile ausgeführt, wobei vorzugsweise die Verzahnung aus einem anderen Material als Kunststoff, aus dem nämlich der Kolben besteht, gefertigt wird. Ebenso sind dort das Gehäuse und der das Gehäuse verschließende Stopfen aus Kunststoff hergestellt.Another door closer is shown in GB 2 292 182 A, where a door closer is described, which reproduces an internal toothing present in a piston. Here, the toothing and the piston are designed as separate components, wherein preferably the toothing of a material other than plastic, from which the piston is made, is made. Similarly, there are the housing and the housing closing plug made of plastic.

Die DE 9413039 U beschreibt einen Türschließer mit Zahnkolben und Ritzel, bei dem zusätzlich zum Gehäuse der Dämpfungskolben und der Schließkolben aus Kunststoff gefertigt sind.DE 9413039 U describes a door closer with toothed piston and pinion, in which in addition to the housing of the damping piston and the closing piston are made of plastic.

Die Aufgabe der Erfindung besteht darin, einen leichten kostengünstigen Türschließer herzustellen, bei dem die üblicherweise anfallende spanabhebende Bearbeitung entfallen kann.The object of the invention is to produce a lightweight, cost-effective door closer, in which the usually resulting machining can be omitted.

Die Aufgabe der Erfindung wird durch die Merkmale des Patentanspruches 1 gelöst.The object of the invention is solved by the features of claim 1.

Zur Kostenreduzierung wird deshalb erfindungsgemäß vorgeschlagen, neben den bekannten Teilen aus Kunststoff, sämtliche bearbeitungsintensiven Teile aus Kunststoff zu fertigen. Diese sind neben dem Dämpfungskolben, dem Federkolben und dem Gehäuse, die Hubkurvenscheibe, die Abtriebsachse und/oder die Andruckrollen, die mit der Hubkurvenscheibe zusammenwirken. Darüber hinaus wird nach einer erfindungsgemäßen Weiterbildung vorgeschlagen, auch die außerhalb des Türschließers vorhandenen Teile, wie Scherengestänge oder Betätigungsarm, bei einem Gleitschienentürschließer in Verbindung mit der Gleitschiene insgesamt aus Kunststoff herzustellen. Dabei ist es unerheblich, ob es sich um einen Bodentürschließer, Rahmentürschließer oder Innentürschließer handelt.To reduce costs is therefore proposed according to the invention, in addition to the known parts made of plastic to manufacture all machining-intensive parts made of plastic. These are in addition to the damping piston, the spring piston and the housing, the Hubkurvenscheibe, the output shaft and / or the pressure rollers, which cooperate with the Hubkurvenscheibe. In addition, it is proposed according to a development of the invention, also the outside of the door closer existing parts, such as scissor linkage or actuator arm to produce at a sliding rail door closer in conjunction with the slide rail of plastic. It does not matter whether it is a floor spring, frame door closer or internal door closer.

Üblicherweise sind die die Kolben umgebenden Zylinderwandungen rund ausgeführt. Dieses liegt insbesondere an den sonst stattfindenden Nacharbeiten, da die runde Form am einfachsten zu bewerkstelligen ist. Will man aber einen preiswerten kleinen Türschließer, d. h. einen Türschlie-ßer, der nicht stark aufbaut, herstellen, kann auch der Querschnitt des Kolbens, d. h. des Dämpfungskolbens und des Federkolbens oder aber auch des Kunststoffkolbens mit Verzahnungen einen anderen Querschnitt als den runden einnehmen, nämlich einen ovalen, rechteckigen, quadratischen oder viereckigen Querschnitt. All diese Formen sind fertigungstechnisch in Kunststoff problemlos herzustellen, da derlei Gehäuse bzw. Kolben im so genannten Spritzgussverfahren hergestellt werden. Diese Verfahren weisen heutzutage aufgrund der verfügbaren Kunststoffe eine enorme Maßtoleranz und damit Passgenauigkeit auf.Usually, the cylinder walls surrounding the pistons are round. This is particularly due to the otherwise occurring rework, since the round shape is the easiest to accomplish. But if you want a cheap small door closer, ie a Türschlie-ßer that does not build up strong, can also cross section of the piston, ie the damping piston and the spring piston or even the plastic piston with teeth take a different cross-section than the round, namely an oval, rectangular, square or square cross section. All of these forms can be produced without problems in plastic, since such housings or pistons are manufactured in the so-called injection molding process. These methods have today due to the available plastics an enormous dimensional tolerance and thus fit on.

Ein derartiges Gehäuse muss aufgrund der geometrischen Querschnitte nicht unbedingt aus einem Teil im Spritzgussverfahren hergestellt werden. Dieses ist auch aus mehreren Segmenten oder Teilsegmenten möglich. Diese Segmente oder Teilsegmente werden über angeformte Passer bzw. Vorsprünge und damit übereinstimmende Vertiefungen im Gegenteil zusammengesetzt bzw. aneinander gesetzt und durch entsprechende Verfahren, wie Verkleben, Ultraschallschweißen, Laserschweißen oder dergleichen, kraft- und formschlüssig dauerhaft untereinander verbunden. Durch diese Verfahren wird die Formstabilität der einzelnen Segmente erhalten. Gleichzeitig ist es in der Ausführung in den einzelnen Segmenten bei dem Gehäuse möglich, auch Kanäle, Bohrungen, Taschen, Ventilsitz oder auch selbst Ventile direkt beim Herstellungsprozess, ohne Nacharbeit, mit ein- bzw. anzuformen. Hierdurch wird der Montageaufwand und damit der Herstellkostenfaktor reduziert.Due to the geometric cross sections, such a housing does not necessarily have to be produced from one part by injection molding. This is also possible from several segments or subsegments. These segments or sub-segments are put together on integrally formed Passer or projections and matching recesses on the contrary or placed together and connected by appropriate methods, such as gluing, ultrasonic welding, laser welding or the like, non-positively and positively permanently. By these methods, the dimensional stability of the individual segments is obtained. At the same time it is possible in the design in the individual segments in the housing, even channels, holes, pockets, valve seat or even valves directly during the manufacturing process, without rework, with or on. As a result, the installation effort and thus the manufacturing cost factor is reduced.

Üblicherweise sind bei Türschließern die Enden durch so genannte Verschlusskappen oder Verschlüsse verschlossen, diese brauchen je nach gefertigten Segment bei dem erfindungsgemäßen Gegenstand nicht unbedingt vorhanden zu sein, da durch das Zusammenfügen der einzelnen einseitig verschlossenen Segmente eine Vormontage einzelner Teile durchaus denkbar ist. An den Segmenten, an denen erst im Nachhinein eine Verschließung möglich ist, werden dann separate Verschlüsse eingebracht. Auch diese Verschlüsse können durch Verkleben, Ultraschallschweißen oder dergleichen kraft- und formschlüssig mit den Segmenten bzw. mit dem Gehäuse kraft- und formschlüssig verbunden werden. Dabei sind neben stumpfen Ausführungen auch mit Rillen, Hinterschnitten oder Bajonettverschlüssen versehene Verschlüsse zu verwenden, um so die Montagezeiten beim Zusammenfügen zu reduzieren.
Auch die Befestigungsvorrichtungen, in Form von entsprechenden Bohrungen, um den Türschließer im fertigen Zustand an seinem angestammten Platz zu montieren, können gleichzeitig bei einer Spritzgussausführung in Kunststoff spanlos angeformt werden. Die Erfindung wird nachfolgend anhand verschiedener schematisch dargestellter Ausführungsbeispiele näher erläutert.Typically, in door closers, the ends are closed by so-called caps or closures, these need not necessarily be present depending on manufactured segment in the subject invention, since the joining of the individual closed-sided segments pre-assembly of individual parts is quite conceivable. Separate closures are then inserted on the segments where it is only possible to close them afterwards. These closures can be non-positively and positively connected by gluing, ultrasonic welding or the like non-positively and positively with the segments or with the housing. there In addition to blunt designs, it is also necessary to use closures provided with grooves, undercuts or bayonet closures in order to reduce assembly times during assembly.
The fastening devices, in the form of corresponding holes to mount the door closer in the finished state at its original place, can be formed without cutting in plastic injection molding in the same time. The invention will be explained in more detail with reference to various schematically illustrated embodiments.

Neben der nachfolgenden Figurenbeschreibung verschiedener Ausführungsbeispiele gemäß eines Obentürschließers ist der erfindungsgemäße Gedanke ebenso auf Bodentürschließer, Rahmentürschließer und Innentürschließer anzuwenden. Bei den Obentürschließern, Rahmentürschlie-ßern und Innentürschließern kann sowohl eine Gestänge, in Form eines Scherengestänges, oder ein Betätigungsarm in Verbindung mit einer Gleitschiene verwendet werden. Auch diese Teile, Gleitschiene, Betätigungsarm und Scherengestänge, sind aus einem die entsprechende Festigkeit aufweisenden Kunststoff hergestellt.In addition to the following description of the figures of various embodiments according to an overhead door closer, the idea according to the invention is also applicable to floor spring closers, frame door closers and internal door closers. In the overhead door closers, frame door locks and interior door closers, both a linkage, in the form of a scissor linkage, or an actuating arm in conjunction with a slide rail can be used. These parts, slide rail, operating arm and scissors linkage are made of a plastic having the appropriate strength.

Der in den Figuren 1 und 2 wiedergegebene Türschließer weist eine Hubkurvenscheibe 1 auf, die von einer Abtriebsachse 3 durchdrungen wird. Die Abtriebsachse 3 ist im oberen Bereich durch eine Abtriebsachsenlagerung 17 und im unteren Bereich durch eine Abtriebsachsenlagerung 16 innerhalb eines Gehäuses 2 gelagert. Das Lager besteht dabei entweder aus einem Sintermaterial oder einem Nagellager bzw. Kugellager. Die Abtriebsachsenlagerungen 16 und 17 können neben dem Gehäuse 2 ebenfalls aus Kunststoff hergestellt sein. Die Kurvenbahnen der Hubkurvenscheibe 1 kommen auf der einen Seite mit einer Andruckrolle 7, die über eine Achse 14 innerhalb eines Dämpfungskolbens 14 gelagert ist, in Berührung. Auf der anderen Seite liegt die Hubkurvenscheibe 1 mit einer Andruckrolle 8, die über eine Achse 15 innerhalb eines Federkolbens 6 gelagert ist, in Berührung. Gegen das andere Ende des Federkolbens 6 kommt eine Schließfeder 13 einerends und andererends gegen eine Federgegenplatte 31 zur Anlage. Die seitlichen Enden des Gehäuses 2 sind durch Verschlüsse 18 und 19, die entweder durch Verkleben, Ultraschallschweißen, Laserschweißen oder dergleichen mit dem Gehäuse 2 kraft- und formschlüssig verbunden sind, verschlossen. Da für die Steuerfunktion eines Türschließers entsprechende Kanäle 20 in Verbindung mit Ventilen 29 notwendig sind, sind diese im Herstellungsprozess gleichzeitig in das Gehäuse 2 spanlos eingeformt worden. Sowohl innerhalb des Dämpfungskolbens 4 als auch im Federkolben 6 sind darüber hinaus während des Fertigungsprozesses dieser Kolben Rückschlagventile 5 gleichzeitig mit eingeformt worden. Es ist jedoch auch möglich, diese Rückschlagventile 5 separat herzustellen, wobei sie in einem solchen Fall auch nur aus Kunststoff bestehen.The illustrated in Figures 1 and 2 door closer has a Hubkurvenscheibe 1, which is penetrated by an output shaft 3. The output shaft 3 is mounted in the upper region by a output shaft bearing 17 and in the lower region by a Abtriebsachsenlagerung 16 within a housing 2. The bearing consists of either a sintered material or a nail bearing or ball bearings. The output shaft bearings 16 and 17 may also be made of plastic next to the housing 2. The cam tracks of Hubkurvenscheibe 1 come on the one hand with a pinch roller 7, which is mounted on an axis 14 within a damping piston 14 in contact. On the other side, the Hubkurvenscheibe 1 with a pinch roller 8, which is mounted on an axis 15 within a spring piston 6, in contact. Against the other end of the spring piston 6 is a closing spring 13 at one end and the other against a spring counter-plate 31 to the plant. The lateral ends of the housing 2 are closed by closures 18 and 19, which are connected by means of gluing, ultrasonic welding, laser welding or the like with the housing 2 non-positively and positively. Since for the control function of a door closer corresponding channels 20 in conjunction with valves 29 are necessary, they have been simultaneously formed without cutting in the manufacturing process in the housing 2. Both inside the damping piston 4 as well as in the spring piston 6 check valves 5 are also molded in addition during the manufacturing process of this piston. However, it is also possible to produce these check valves 5 separately, and in such a case they also consist only of plastic.

Um ein solches Gehäuse 2 an einer Tür oder oberhalb der Tür zu befestigen, ist eine Befestigungsvorrichtung 28 gleichzeitig in oder an das Gehäuse 2 während des Herstellprozesses spanlos angeformt worden.In order to secure such a housing 2 to a door or above the door, a fastening device 28 has been simultaneously formed without cutting in or on the housing 2 during the manufacturing process.

Es versteht sich, durch den Weg der Kunststoffverarbeitung, ohne nachträgliche Bearbeitung, dass neben der durchgehenden Zylinderbohrung für den Dämpfungskolben 4, den Federkolben 6 und die Schließfeder 13, die im Stand der Technik rund ausgeführt sind, dass auch andere Formen möglich sind. Dieses sind insbesondere eine ovale Form, was gleichzeitig bedeuten würde, dass der Schließer in seinen Abmaßen wesentlich schmaler wäre, oder eine rechteckige oder quadratische Form.It is understood, by the way the plastic processing, without subsequent processing, that in addition to the continuous cylinder bore for the damping piston 4, the spring piston 6 and the closing spring 13, which are executed in the prior art around, that other shapes are possible. These are in particular an oval shape, which would mean at the same time that the closer would be much narrower in dimensions, or a rectangular or square shape.

In der Figur 2, bei der ein einteiliges Gehäuse wiedergegeben wird, wird deutlich, dass aufgrund von gleichen Materialien sowohl für den Dämpfungskolben 4 als auch den Federkolben 6 und die Hubkurvenscheibe 1 mit der Abtriebsachse 3 aufgrund von Erwärmungen, beispielsweise durch Sonneneinstrahlung, bei einem solchen Türschließer keine Probleme hinsichtlich der Wärmeausdehnung auftreten können, da das verwendete Material für alle Bauteile den gleichen Ausdehnungskoeffizienten hat. Dieses ist im Stand der Technik nicht gegeben, da bei der Verwendung von beispielsweise Stahl oder Leichtmetall in Verbindung mit Kunststoff unterschiedlichste Ausdehnungskoeffizenten wirken, was zwangsläufig zu Leckagen bzw. zu Ausfällen einer solchen Tür führen muss.In the figure 2, in which a one-piece housing is reproduced, it is clear that due to the same materials for both the damping piston 4 and the spring piston 6 and the Hubkurvenscheibe 1 with the output shaft 3 due to heating, for example by solar radiation, in such Door closer no problems in terms of thermal expansion can occur because the material used for all components has the same coefficient of expansion. This is not the case in the prior art, since when using, for example, steel or light metal in conjunction with plastic different expansion coefficients act, which inevitably lead to leaks or failure of such a door.

In einem Beispiel der Figuren 3 und 4 nach dem Stand der Technik wird ein Zahnstangentürschließer mit einem Kolben 10, der aus Kunststoff besteht und eine Innenverzahnung 11 aufweist, wiedergegeben. Mit der Verzahnung 11 steht ein Ritzel 12 in Wirkverbindung, wobei das Ritzel 12 auf der Abtriebsachse 3 kraft- und formschlüssig mit angeformt ist. Neben dem Gehäuse 9 sind bei diesem Ausführungsbeispiel der Kolben 10 mit seiner Verzahnung 11 und die Abtriebsachse 3 mit ihrem Ritzel 12 ebenfalls aus Kunststoff hergestellt. Somit hat der Türschließer die gleichen Eigenschaften der Figuren 1 und 2, d. h. auch bei diesem Türschließer würde eine Erwärmung aufgrund der gleichen Ausdehnungskoeffizienten hinsichtlich der Funktion keine Ausfälle mit sich bringen. Die Enden des Gehäuses 9 sind ebenfalls durch Verschlüsse 18 und 19, die ebenfalls durch Verkleben, Ultraschallschweißen, Laserschweißen oder dergleichen kraft- und formschlüssig mit dem Gehäuse 9 verbunden sind, verschlossen.In an example of Figures 3 and 4 of the prior art, a rack and pinion door closer is shown with a piston 10 made of plastic and having internal teeth 11. With the teeth 11 is a pinion 12 in operative connection, wherein the pinion 12 is formed on the output shaft 3 non-positively and positively with. In addition to the housing 9, the piston 10 with its toothing 11 and the output shaft 3 with its pinion 12 are also made of plastic in this embodiment. Thus, the door closer has the same characteristics of Figures 1 and 2, d. H. Even with this door closer heating due to the same expansion coefficients would bring with respect to the function no failures. The ends of the housing 9 are also by closures 18 and 19, which are also connected by gluing, ultrasonic welding, laser welding or the like non-positively and positively connected to the housing 9, closed.

Bei der Ausführung eines Bodentürschließers ganz in Kunststoff wird natürlich auch der zu dem Bodentürschließer gehörende Zementkasten ebenfalls aus Kunststoff hergestellt.In the execution of a floor door closer entirely in plastic, of course, also belonging to the bottom door closer cement box is also made of plastic.

Das in der Figur 5 dargestellte Ausführungsbeispiel zeigt ein Gehäuse eines Türschließers, welches aus verschiedenen Segmenten 21 und 22 zusammengesetzt wird. Dabei ist es möglich, verschiedene Segmente fertigungstechnisch einzeln auszuführen, so beispielsweise das Segment 22, welches als einseitig offenes Segment mit angeformten Befestigungen 28 wiedergegeben worden ist. An den zu verbindenden Stellen haben die Segmente 21 und 22 Passer 26 und Vertiefungen 27, die beim Aneinanderfügen ineinander eingreifen und beim anschließenden Verfahren zur Verbindung der Segmente 21 und 22 eine kraft- und formschlüssige und darüber hinaus formstabile Form eingehen. Der Kolbenraum 30, der sich innerhalb der Segmente 21 und 22 befindet, wird auf der offenen Seite des Segmentes 21 durch einen Verschluss 19 verschlossen. In dem Segment 21 ist darüber hinaus eine Bohrung 23 für die in der Figur 1 wiedergegebenen Abtriebsachsenlagerungen 16 und 17 gleichzeitig spanlos mit eingeformt.The embodiment shown in Figure 5 shows a housing of a door closer, which is composed of different segments 21 and 22. It is possible to perform different segments manufacturing technology individually, such as the segment 22, which has been shown as unilaterally open segment with molded fasteners 28. At the points to be joined, the segments 21 and 22 have passer 26 and recesses 27, which engage in the joining together and enter into a subsequent positive and positive locking and beyond dimensionally stable shape in the subsequent process for connecting the segments 21 and 22. The piston chamber 30, which is located within the segments 21 and 22, is on the open side of the segment 21 is closed by a closure 19. In the segment 21, a bore 23 for the reproduced in the figure 1 output shaft bearings 16 and 17 is also formed without cutting.

Neben der Teilung der Segmente 21 und 22 ist es auch möglich, die Segmente in anderer Form zu teilen, wie es die Figur 6 wiedergibt. Hier sind Segmente 24 und 25 dargestellt, die in Längsrichtung des Türschließer über Passer 26 und Vertiefungen 27 miteinander verbunden werden. Gleichzeitig ist in diesem Ausführungsbeispiel der Figur 6 der Kolbenraum 30 als quadratischer Kolbenraum wiedergegeben worden.In addition to the division of the segments 21 and 22, it is also possible to divide the segments in a different form, as shown in FIG. 6. Here, segments 24 and 25 are shown, which are connected to each other in the longitudinal direction of the door closer via register 26 and recesses 27. At the same time in this embodiment of Figure 6, the piston chamber 30 has been reproduced as a square piston chamber.

Bei den vorgenannten Ausführungsbeispielen, die keinen Anspruch auf Vollständigkeit erheben, wird davon ausgegangen, dass es sich um Türschließer jeglicher Art handelt, die ohne nachträgliche Bearbeitung der Einzelteile und Segmente zusammengebaut werden. Dabei kann ein solcher Zusammenbau auch in einem automatischen Verfahren durchgeführt werden. Die aus Kunststoff, vorzugsweise in einem spritztechnischen Verfahren, hergestellten Teile werden, ohne nachträgliche weitere Bearbeitung, durch Verkleben, Ultraschallschweißen, Laserschweißen oder dergleichen untereinander kraft- und formschlüssig verbunden. Als Kunststoff kann ein carbonfaser- oder glasfaserverstärkter Kunststoff verwendet werden. In the aforementioned embodiments, which are not exhaustive, it is assumed that they are door closers of any kind, which are assembled without subsequent processing of the items and segments. In this case, such an assembly can also be carried out in an automatic process. The parts made of plastic, preferably in an injection molding process, are non-positively connected to one another by means of gluing, ultrasonic welding, laser welding or the like without further subsequent processing. As plastic, a carbon fiber or glass fiber reinforced plastic can be used.
