Description

Die Erfindung betrifft ein in Offenstellung verrastbares Türschliessergestänge nach dem Oberbegriff des Anspruchs 1.The invention relates to a door closer linkage that can be locked in the open position according to the preamble of claim 1.

Bei einem nach der DE-A 1 784038 bekannten Türschliessergestänge dieser Art sind die beiden Schenkel durch einen einstückigen Bolzen miteinander verbunden. Eine Nockenscheibe für die Verrastung ist auf einen verzahnten Abschnitt des Bolzens aufgesetzt. An seinem freien Ende weist der Bolzen eine weitere Verzahnung auf, die in eine Gegenverzahnung des einen Schenkels gesteckt ist. Der Bolzen ist in seiner Herstellung sehr aufwendig und daher kostspielig. Überdies kann man die Nockenscheibe nicht austauschen, ohne das ganze Gelenk auseinanderzunehmen.In a door closer linkage of this type known from DE-A 1 784038, the two legs are connected to one another by an integral bolt. A cam disc for locking is placed on a toothed section of the bolt. At its free end, the bolt has a further toothing, which is inserted into a counter toothing of one leg. The bolt is very complex to manufacture and therefore expensive. Furthermore, the cam disc cannot be replaced without disassembling the entire joint.

Aufgabe der Erfindung ist es demgegenüber, das Raststück bei einfacher Ausbildung des Gelenkzapfens den örtlichen Verhältnissen angepasst und auch im Falle des Ersatzes durch einen anderen austauschen zu können.In contrast, the object of the invention is to adapt the locking piece to the local conditions with a simple design of the pivot pin and also to be able to replace it with another in the event of replacement.

Die Lösung dieser Aufgabe ist im Kennzeichen des Anspruchs 1 angegeben.The solution to this problem is specified in the characterizing part of claim 1.

Wesentlich für die Erfindung ist die besondere Art der Aufteilung des Gelenkzapfens in ein Aufsatzteil und ein Raststück mit je einer zugeordneten Schraube. Durch das konstruktive Zusammenwirken der Merkmale des Anspruchs 1 wird die Aufgabe gelöst.What is essential to the invention is the special type of division of the pivot pin into an attachment part and a locking piece, each with an associated screw. The object is achieved by the constructive interaction of the features of claim 1.

Die Erfindung wird im folgenden an Ausführungsbeispielen unter Hinweis auf die beigefügten Zeichnungen erläutert.

Fig. 1 zeigt einen in Offenstellung verrasteten Türschliesser 2 mit zwei durch ein Gelenk 4 verbundenen Schenkeln 6, 8, deren freie Enden an einer Tür 10 bzw. einem Türstock 12 in bekannter Weise angelenkt sind. Gestrichelt ist der Schenkel 6 in Schliessstellung der Tür dargestellt. Das Gelenk 4 weist einen mit dem Schenkel 6 fest verbundenen Gelenkzapfen 14 auf. Dieser Gelenkzapfen 14 ist mit einer Abflachung 16 versehen, symmetrisch zu der je zwei Rastausnehmungen 18, 20, 22, 24 liegen. In dem Schenkel 8 befindet sich ein unter Federdruck stehendes Rastelement 26, das an die Abflachung 16 angreift, wenn die Tür geschlossen ist (und dabei die Feder entspannt ist) oder in Öffnungsstellung der Tür in eine der Rastausnehmungen 18, 20, 22, 24 eingreift. Das Rastelement 26 ist zylindrisch dargestellt und entsprechend hohlzylindrisch sind die Ausnehmungen 18, 20, 22, 24 dargestellt. Stattdessen kann aber auch eine Kugelverrastung vorgesehen sein, also das Rastelement kugelförmig sein und entsprechend hohlkugelförmig die Rastausnehmungen. Die Rastausnehmungen 18, 22 sind etwa einer Öffnungsstellung der Tür von 90° zugeordnet, die Rastausnehmungen 20, 24 etwa einer Öffnungsstellung der Tür von 170°. Die die Rastausnehmungen 18, 20, 22, 24 in Öffnungsrichtung begrenzenden Kanten 28, 30, 32, 34 sind mit einem grösseren Krümmungsradius abgerundet als die die Rastausnehmungen 18, 20, 22, 24 in Schliessrichtung begrenzenden Kanten 36, 38, 40, 42. Dadurch wird die Verrastung in Schliessrichtung der Tür 10 schwergängiger als in Öffnungsrichtung der Tür 10.1 shows a door closer 2 locked in the open position with two legs 6, 8 connected by a joint 4, the free ends of which are articulated to a door 10 or a door frame 12 in a known manner. The leg 6 is shown in dashed lines in the closed position of the door. The hinge 4 has a hinge pin 14 which is firmly connected to the leg 6. This pivot pin 14 is provided with a flattened portion 16, symmetrical to which two latching recesses 18, 20, 22, 24 are located. In the leg 8 there is a spring element locking element 26 which engages the flat 16 when the door is closed (and the spring is relaxed) or engages in one of the locking recesses 18, 20, 22, 24 in the open position of the door . The locking element 26 is shown cylindrically and the recesses 18, 20, 22, 24 are shown correspondingly hollow cylindrical. Instead, however, a ball catch can also be provided, that is to say the catch element be spherical and the catch recesses correspondingly hollow spherical. The latching recesses 18, 22 are approximately assigned to an open position of the door of 90 °, the latching recesses 20, 24 approximately to an open position of the door of 170 °. The edges 28, 30, 32, 34 delimiting the recesses 18, 20, 22, 24 in the opening direction are rounded off with a larger radius of curvature than the edges 36, 38, 40, 42 delimiting the recesses 18, 20, 22, 24 in the closing direction. As a result, the locking in the closing direction of the door 10 becomes more difficult than in the opening direction of the door 10.

Das Rastelement 26 steht unter dem Druck eines Kolbens 44, auf den eine Schraubenfeder 46 wirkt. Die Schraubenfeder 46 stützt sich ihrerseits an einer Stellschraube 48 ab. Der Kolben 44 und die Schraubenfeder 46 sind in einem Zylinder 50 eingeschlossen, in dem sich ein Innengewinde 52 für die Schraube 48 befindet. Der Zylinder 50 ist auf der Seite, von der die Schraube 48 zugänglich sein muss, offen und bildet einen Abschnitt des Schenkels 8. Ein zweiter Abschnitt 54 des Schenkels 8 ist mit dem ersten Abschnitt 50 durch eine zweiendige Stellschraube 56 verbunden, die in eine Gewindebuchse 58 im Abschnitt 50 und eine zweite Gewindebuchse (nicht dargestellt) im Abschnitt 54 eingreift. Die Gewinde auf den beiden Enden der Stellschraube 56 sind gegenläufig, so dass durch Verdrehen der Stellschraube 56 durch Angreifen an einen in ihrer Mitte befindlichen Mehrkant 60 der Abstand der Abschnitte 50, 54 zur Anpassung an die örtlichen Verhältnise eingestellt werden kann. Die Festlegung der Abschnitte 50, 54 erfolgt dann durch Anziehen von Kontermuttern 62, 64.The locking element 26 is under the pressure of a piston 44, on which a coil spring 46 acts. The coil spring 46 is in turn supported on an adjusting screw 48. The piston 44 and the coil spring 46 are enclosed in a cylinder 50 in which there is an internal thread 52 for the screw 48. The cylinder 50 is open on the side from which the screw 48 must be accessible and forms a section of the leg 8. A second section 54 of the leg 8 is connected to the first section 50 by a double-ended set screw 56 which is inserted into a threaded bushing 58 engages in section 50 and a second threaded bushing (not shown) in section 54. The threads on the two ends of the adjusting screw 56 are in opposite directions, so that by turning the adjusting screw 56 by engaging a polygon 60 located in its center, the spacing of the sections 50, 54 can be adjusted to adapt to the local conditions. Sections 50, 54 are then fixed by tightening lock nuts 62, 64.

An dem dem Türstock 12 zugewandten Ende des Abschnitts 54 ist um eine horizontale Achse 66 schwenkbar ein Auge 68 angelenkt.At the end of the section 54 facing the door frame 12, an eye 68 is pivoted about a horizontal axis 66.

Bei der Ausführungsform nach Fig. 4 ist der Gelenkbolzen 14' zweiteilig. Er besteht aus einem Konus 70 mit einem Ringflansch 72, der in eine konische Ausnehmung 74 des Schenkels 6 eingesetzt ist und aus einem entsprechend Fig. 3 ausgebildeten Raststück 76. Das Raststück 76 ist mit dem Konus 70 drehsicher durch Kupplungskugeln 78 zu verbinden. Die Verbindung erfolgt mittels einer Schraube 80, die von unten in den Schenkel 6 eingeführt wird und in ein Innengewinde 82 des Raststücks eingreift. Um den Schenkel 8 an dem Gelenk 14' zu sichern, ist eine Schraube 84vorgesehen, die eine Ringscheibe 86 durchdringt und von oben in ein Innengewinde 88 des Raststücks 76 eingreift. Durch Lockern und Wiederanziehen der Schraube 80 kann man das Raststück 76 in gewünschter Winkellage relativ zu dem Schenkel 6 festlegen. Diese Winkellagen sind allerdings nicht formschlüssig festgelegt.In the embodiment according to FIG. 4, the hinge pin 14 'is in two parts. It consists of a cone 70 with an annular flange 72, which is inserted into a conical recess 74 of the leg 6 and of a locking piece 76 designed according to FIG. 3. The locking piece 76 is to be connected to the cone 70 in a rotationally secure manner by coupling balls 78. The connection is made by means of a screw 80, which is inserted into the leg 6 from below and engages in an internal thread 82 of the locking piece. In order to secure the leg 8 to the joint 14 ', a screw 84 is provided which penetrates an annular disk 86 and engages in an internal thread 88 of the locking piece 76 from above. By loosening and tightening the screw 80, the locking piece 76 can be fixed in the desired angular position relative to the leg 6. However, these angular positions are not form-fitting.

Bei der Ausführungsform nach Fig. ist eine formschlüssige Festlegung des Raststücks 90 des Gelenks 14" in verschiedenen Winkellagen möglich.In the embodiment according to FIG., The locking piece 90 of the Joint 14 " possible in different angular positions.

Hierzu ist in dem Schenkel 6 eine Bohrung 92 mit Längsverzahnung 94 vorgesehen, in die eine entsprechende Aussenlängsverzahnung 96 an einem Aufsatzteil 98 für das Raststück in gewünschter Winkellage eingesteckt werden kann. Das Raststück 90 und das Aufsatzteil 98 können zusammen einstückig ausgebildet sein. Im dargestellten Ausführungsbeispiel ist das Raststück 90 auf das Aufsatzteil 98 aufschraubbar. Eine der Schraube 80 in Fig.4 entsprechende Schraube 100 greift in ein Innengewinde 102 des Aufsatzstücks 98 ein und hält das Aufsatzstück am Schenkel 6 fest. Der Schenkel 8 wird an dem Raststück 90 mittels einer Schraube 104 und einer Ringscheibe 106 ebenso gesichert wie bei der Ausführungsform nach Fig. 4.For this purpose, a bore 92 with longitudinal toothing 94 is provided in the leg 6, into which a corresponding external longitudinal toothing 96 can be inserted on an attachment part 98 for the locking piece in the desired angular position. The locking piece 90 and the top part 98 can be formed together in one piece. In the illustrated embodiment, the locking piece 90 can be screwed onto the top part 98. A screw 100 corresponding to the screw 80 in FIG. 4 engages in an internal thread 102 of the attachment piece 98 and holds the attachment piece firmly on the leg 6. The leg 8 is secured to the locking piece 90 by means of a screw 104 and an annular disk 106 as well as in the embodiment according to FIG. 4.

Der Schenkel 6 weist einen von seiner freien Stirnseite ausgehenden, bis zur konischen Ausnehmung 74 reichenden Schlitz 71 auf. In dem Abschnitt 73 des Schenkels 6, der durch den Schlitz 71 begrenzt ist, befindet sich ein Innengewinde. In dieses Innengewinde ist durch eine Bohrung 75 im anderen durch den Schlitz 71 begrenzten Abschnitt eine Schraube 79 zu schrauben. Mittels dieser Schraube 79 können die Abschnitte 73, 77 aneinandergezogen werden. Dadurch wird der Konus 70 drehfest gesichert.The leg 6 has a slot 71 extending from its free end face and extending as far as the conical recess 74. In the section 73 of the leg 6, which is delimited by the slot 71, there is an internal thread. A screw 79 is to be screwed into this internal thread through a bore 75 in the other section delimited by the slot 71. The sections 73, 77 can be pulled together by means of this screw 79. As a result, the cone 70 is secured against rotation.

Bei der Montage wird der Türschliesser mit seinen Schenkeln 6, 8 bei losem Konus 70 in üblicher Weise montiert, wobei sich das Rastelement 26 in derjenigen Rastausnehmung 18, 20, 22, 24 befindet, die der gewünschten Offenstellung der Tür entspricht. Dann wird die Tür in die gewünschte Offenstellung geschwenkt und die Schraube 79 angezogen. Man ist dann sicher, dass die Tür in der Offenstellung die gewünschte Winkellage zu ihrem Rahmen beim späteren Öffnen automatisch wieder einnimmt.During assembly, the door closer with its legs 6, 8 is mounted in the usual way with the cone 70 loose, the latching element 26 being located in the latching recess 18, 20, 22, 24 which corresponds to the desired open position of the door. Then the door is pivoted into the desired open position and the screw 79 is tightened. It is then certain that the door in the open position will automatically assume the desired angular position with respect to its frame when it is opened later.
