Description

Die Erfindung betrifft ein Drehlager für Fensterflügel, insbesondere für um eine seitlich und lotrecht verlaufende Achse bewegliche Drehflügel, die als Mittel- bzw. Zwischenflügel in drei- oder mehrflügelige Fenster mit Blendrahmen ohne Zwischenpfosten eingebaut sind, bestehend aus einer an der raumseitigen Stirnfläche des Blendrahmens aufliegend montierbaren Rahmen-Lagerhälfte und einer an der Umfangsfläche des Flügelüberschlags im Bereich einer Flügelecke montierbaren Flügel-Lagerhälfte, wobei jeweils eine Lagerhälfte mit einem Lagerzapfen und die andere Lagerhälfte mit einer Lagerbüchse zur Aufnahme des Lagerzapfens versehen ist, wobei weiterhin die Rahmen-Lagerhälfte aus einem Befestigungsteil sowie einem hiervon getragenen Verstellteil besteht, das parallel zur Blendrahmenebene über einen begrenzten Verschiebebereich justierbar ist, wobei das Verstellteil entweder den Lagerzapfen trägt oder die Lagerbüchse enthält, und wobei das Verstellteil von einem in einer Ausnehmung oder einem Durchbruch des Befestigungsteils verschiebbar geführten und abgestützten Kulissentein gebildet ist, an dem eine parallel zur Verschieberichtung verlaufende Schraubspindel angreift, die ihr Widerlager am Befestigungsteil hat sowie mindestens ein von außen zugängliches Endes aufweist, das mit einem Eingriff für ein Verstellwerkzeug versehen ist.The invention relates to a pivot bearing for window sashes, in particular for rotary sashes movable about a laterally and perpendicularly extending axis, which are installed as central or intermediate sashes in three- or multi-sash windows with frames without intermediate posts, consisting of one lying on the face end face of the frame mountable frame bearing half and a wing bearing half which can be mounted on the peripheral surface of the sash flap in the area of a wing corner, one bearing half each being provided with a bearing journal and the other bearing half being provided with a bearing bush for receiving the bearing journal, the frame bearing half also comprising a fastening part and an adjustment part carried by it, which can be adjusted parallel to the frame level over a limited displacement range, the adjustment part either carrying the bearing journal or containing the bearing bush, and wherein the adjustment part moves from one into one r recess or an opening of the fastening part is slidably guided and supported link block, which is attacked by a screw spindle running parallel to the direction of displacement, which has its abutment on the fastening part and has at least one end accessible from the outside, which is provided with an engagement for an adjusting tool.

Ein Drehlager für Fensterflügel mit dieser Merkmalsausstattung gehört durch DE-A- 27 03 995 zum Stand der Technik. Es wird dabei als Ecklager, insbesondere für Drehkippfenster eingebaut und hat eine Ausbildung, die zumindest eine Justierung des Flügels relativ zum Blendrahmen in horizontaler Richtung und parallel zur Blendrahmenebene ermöglicht.A pivot bearing for window sash with this feature is part of the prior art by DE-A-27 03 995. It is installed as a corner bearing, in particular for tilt-and-turn windows, and has a design which at least allows the sash to be adjusted relative to the window frame in the horizontal direction and parallel to the window frame plane.

Nachteilig bei dem bekannten Drehlager ist, daß dessen Rahmen-Lagerhälfte eine beträchtliche Bauhöle benötigt, weil sie aus einem Lagergehäuse besteht, in dem sich die Flügel-Lagerhälfte in einer durch eine Boden begrenzten Tasche über ein besonderes Auflager verschiebbar abstützen muß. Das Auflager der Flügel-Lagerhälfte ist dabei so angeordnet und ausgebildet, daß die als Verstellmittel benutzte Schraubspindel im Gehäuse der Rahmen-Lagerhälfte oberhalb des Bodens der Tasche, aber unterhalb des Lagerteils der Flügel-Rahmenhälfte liegen muß und durch den dort benötigten Einbauraum zu der ungünstigen Gesamt-Bauhöhe des Drehlagers führt.A disadvantage of the known pivot bearing is that its frame bearing half requires a considerable construction cavity because it consists of a bearing housing in which the wing bearing half has to be displaceably supported in a pocket limited by a base via a special support. The support of the wing bearing half is arranged and designed so that the screw spindle used as an adjusting means in the housing of the frame bearing half must be above the bottom of the pocket, but below the bearing part of the wing frame half and due to the installation space required there to the unfavorable Overall height of the pivot bearing leads.

Bei einem anderen bekannten Drehlager ist das Befestigungsteil der Rahmen-Lagerhälfte als eine schmale, langgestreckte Platte gestaltet, die an ihrer Stirnseite einen längsverlaufenden Steg trägt. Mit diesem Steg steht über eine rückseitige Längsnut das Verstellteil in formschlüssigem Verschiebeeingriff, welches wiederum mit Langlöchern versehen ist, die von Klemmschrauben durchgriffen sind, welche in Gewinden des Befestigungsteils sitzen.In another known pivot bearing the fastening part of the frame bearing half designed as a narrow, elongated plate, which carries a longitudinal web on its front side. With this web, the adjustment part is in a form-fitting sliding engagement via a rear longitudinal groove, which in turn is provided with elongated holes which are penetrated by clamping screws which sit in the threads of the fastening part.

Nach Lockern der Klemmschrauben läßt sich das Verstellteil relativ zum Befestigungsteil über den durch die Langlöcher eingegrenzten Verstellbereich hinweg verschieben sowie in jeder möglichen Verschiebelage durch Anziehen der Klemmschrauben wieder festlegen. Es ist daher möglich, die Einbaulage des jeweils über ein Drehlager-Paar am Blendrahmen aufgehängten Fensterflügels zum Blendrahmen zu justieren.After loosening the clamping screws, the adjustment part can be moved relative to the fastening part over the adjustment range delimited by the elongated holes and can be fixed again in any possible displacement position by tightening the clamping screws. It is therefore possible to adjust the installation position of the window sash, which is suspended from the frame in each case via a pair of pivot bearings, in relation to the frame.

Eine Unzulänglichkeit dieser bekannten Drehlager liegt darin, daß sich das Verstellteil relativ zum Befestigungsteil ohne weiteres verschieben kann, sobald die Klemmschrauben gelockert sind. Es ist daher in der Regel nötig, die Justierarbeiten für den Fensterflügel am Blendrahmen mit zwei Personen zu bewirken. Dies in der Weise, daß jeweils eine Person den Flügel hält und ausrichtet, während die andere Person die Klemmschrauben zwischen dem Befestigungsteil und dem Verstellteil lockert und wieder anzieht. Da die Koordination der von beiden Personen vorzunehmenden Manipulationen eine gewisse Geschicklichkeit erfordert, sind die an den bekannten Drehlagern vorzunehmenden Justierarbeiten verhältnismäßig umständlich und zeitraubend.An inadequacy of these known pivot bearings lies in the fact that the adjustment part can easily move relative to the fastening part as soon as the clamping screws are loosened. It is therefore usually necessary to carry out the adjustment work for the window sash on the window frame with two people. This in such a way that one person holds and aligns the wing, while the other person loosens the clamping screws between the fastening part and the adjusting part and then pulls them back on. Since the coordination of the manipulations to be carried out by both persons requires a certain skill, the adjustment work to be carried out on the known pivot bearings is relatively cumbersome and time-consuming.

Der Erfindung ist zur Ausräumung dieser Nachteile die Aufgabe gestellt, gattungsgemäße Drehlager zur schaffen, die eine laiengerechte, also problemlos und schnell durchzuführende Justierung durch nur eine Bedienungsperson gewährleisten.To overcome these disadvantages, the invention is based on the task of creating generic pivot bearings which ensure that only one operator can make adjustments that are suitable for laymen and are therefore easy and quick to carry out.

Solche Drehlager zeichnen sich dabei nach der Erfindung wesentlich dadurch aus, daß die Lagerbüchse oder der Lagerzapfen nahe dem vom Blendrahmen abgewendeten Ende des Kulissensteins sitzt, während die Schraubspindel in der Nähe von dessen Blendrahmen zugewendeten Ende angreift.Such rotary bearings are characterized according to the invention essentially in that the bearing bush or the bearing pin sits near the end of the sliding block facing away from the frame, while the screw engages near its end facing the frame.

Ohne daß irgendwelche Klemmelemente zwischen dem Befestigungsteil und dem Verstellteil gelockert und wieder angezogen werden müßten, kann bei einem erfindungsgemäßen Drehlager eine stufenlose und zugleich formschlüssige Verlagerung des als Verstellteil dienenden Kulissensteins gegenüber dem Befestigungsteil vorgenommen werden.Without any clamping elements between the fastening part and the adjustment part having to be loosened and tightened again, a stepless and at the same time positive displacement of the sliding block serving as the adjustment part relative to the fastening part can be carried out in a pivot bearing according to the invention.

Es gibt zwei Möglichkeiten für das Zusammenwirken der Schraubspindel einerseits mit dem Befestigungsteil und andererseits mit dem Verstellteil. Im einen Falle lagert die Schraubspindel drehbar und verschiebesicher im Befestigungsteil und steht mit einem Gewindeabschnitt des Kulissensteins in Eingriff. Im anderen Falle kann jedoch die Schraubspindel in mindestens einem Gewindeabschnitt des Befestigungsteils für schraubende Bewegung gehalten werden, während sie relativ zum Kulissenstein eine zwar drehbare, aber unverschiebliche Fixierung hat.There are two possibilities for the screw spindle to interact with the fastening part on the one hand and with the adjustment part on the other hand. In one case, the screw spindle is rotatably and non-displaceably mounted in the fastening part and is in engagement with a threaded section of the sliding block. In the other case, however, the screw spindle can be held in at least one threaded section of the fastening part for screwing movement, while it has a rotatable but non-displaceable fixation relative to the sliding block.

Eine stabile Ausgestaltung der Drehlager ergibt sich dadurch, daß der Kulissenstein von einem Boden oder mindestens einer Rippe bzw. einem Steg des Befestigungsteils untergriffen und/oder abgestützt ist.A stable design of the pivot bearing results from the fact that the sliding block is gripped and / or supported by a base or at least one rib or a web of the fastening part.

Die Rippe bzw. der Steg kann der Ausnehmung bzw. dem Durchbruch des Befestigungsteils an dem vom Blendrahmen abgewendeten Ende zugeordnet werden und dort in eine Abstufung am vorderen Ende des Kulissensteins eingreifen.The rib or the web can be assigned to the recess or the opening of the fastening part at the end facing away from the frame and there engage in a gradation at the front end of the sliding block.

Gegen Verschwenken um die Längsachse der Schraubspindel läßt sich der Kulissenstein einfach dadurch schützen, daß er an seinem hinteren Ende eine zur Längsachse der Schraubspindel parallele, aber normal zu seiner Hauptebene ausgerichtete Fläche aufweist, die sich an einer zugeordneten Widerlagerfläche des Befestigungsteils abstützt.Against pivoting about the longitudinal axis of the screw spindle, the sliding block can be protected simply by having at its rear end a surface parallel to the longitudinal axis of the screw spindle, but oriented normal to its main plane, which is supported on an associated abutment surface of the fastening part.

Die Fig. 1 der Zeichnung stellt ein als Dreiflügel-Fenster ausgeführtes Mehrflügel-Fenster 1 dar, welches den Blendrahmen 2 sowie zwei Seitenflügel 3 und 4 und einen Mittelflügel 5 aufweist.1 of the drawing shows a multi-wing window 1 designed as a three-wing window, which has the window frame 2 and two side wings 3 and 4 and a middle wing 5.

Der Blendrahmen 2 ist dabei ohne vertikale Zwischenpfosten ausgeführt. Bei in Schließlage am Blendrahmen 2 anliegenden Flügeln 3, 4 und 5 wirken daher deren einander benachbarte, aufrechte Flügelholme 6 und 7 bzw. 8 und 9 unmittelbar zusammen, um an den betreffenden Stellen den Dichtschluß des Mehrflügel-Fensters 1 zu bewirken.The window frame 2 is designed without vertical intermediate posts. When in the closed position on the frame 2 wings 3, 4 and 5 therefore their adjacent, upright wing spars 6 and 7 or 8 and 9 interact directly to bring about the tight closure of the multi-sash window 1 at the relevant points.

Die Zeichnung zeigt in Fig. 1, daß einerseits die aufrechten Flügelholme 6 und 7 des linken Seitenflügels 3 und des Mittelflügels 5 einander zugeordnet sind, während andererseits die aufrechten Flügelholme 8 und 9 des Mittelflügels 5 sowie des rechten Seitenflügels 4 unmittelbar miteinander in Wirkverbindung treten. Der aufrechte Flügelholm 10 des linken Seitenflügels 3, der aufrechte Flügelholm 11 des rechten Seitenflügels 4 sowie die horizontalen Flügelholme 12 bis 17 aller drei Flügel 3, 4 und 5 kommen hingegen mit ihrem sogenannten Überschlag an den aufrechten Rahmenholmen 18 und 19 bzw. den horizontalen Rahmenholmen 20 und 21 des Blendrahmens 2 zur Dichtungsanlage.The drawing shows in Fig. 1 that on the one hand the upright wing spars 6 and 7 of the left side wing 3 and the middle wing 5 are assigned to each other, while on the other hand the upright wing spars 8 and 9 of the middle wing 5 and the right side wing 4 come into direct connection with each other. The upright wing spar 10 of the left side wing 3, the upright wing spar 11 of the right side wing 4 and the horizontal wing spars 12 to 17 of all three wings 3, 4 and 5, however, come with their so-called rollover on the upright frame spars 18 and 19 or the horizontal frame spars 20 and 21 of the frame 2 to the sealing system.

Der linke Seitenflügel 3 und der rechte Seitenflügel 4 des Mehrflügel-Fensters 1 sind jeweils als sogenannte Stulpflügel ausgeführt, die an ihren aufrechten Flügelholmen 6 bzw. 9 jeweils eine sogenannte Schlagleiste 22 bzw. 23 tragen können, mit der sie innenseitig auf den aufrechten Flügelholmen 7 und 8 des Mittelflügels 5 zur Dichtungsauflage kommen. Folglich ist der Mittelflügel 5 im Verhältnis zu den beiden Seitenflügeln 3 und 4 als sogenannter unterschlagender Flügel ausgeführt.The left side wing 3 and the right side wing 4 of the multi-sash window 1 are each designed as so-called sash sashes, which can each carry a so-called impact bar 22 or 23 on their upright wing spars 6 and 9, respectively, with which they are on the inside on the upright wing spars 7 and 8 of the middle wing 5 come to the sealing pad. Consequently, the middle wing 5 is designed in relation to the two side wings 3 and 4 as a so-called underlapping wing.

Sämtliche Flügel 3 bis 5 des Mehrflügel-Fensters können am Blendrahmen 2 als reine Drehlfügel angeschlagen werden.All of the sashes 3 to 5 of the multi-sash window can be attached to frame 2 as pure rotating sashes.

Unter bestimmten Voraussetzungen hinsichtlich der Beschlagausstattung lassen sich aber die Seitenflügel 3 und 4 des Mehrflügel-Fensters 1 auch als sogenannte Drehkippflügel am Blendrahmen 2 anschlagen. Der Mittelflügel 5 ist jedoch in diesem Falle immer nur als reiner Drehflügel vorgesehen.Under certain conditions with regard to the fitting equipment, the side wings 3 and 4 of the multi-wing window 1 can also be attached to the frame 2 as so-called tilt and turn sashes. In this case, the middle wing 5 is only ever provided as a pure rotating wing.

Der Mittelflügel 5 wirkt mit den horizontalen Rahmenholmen des Blendrahmens 2 jeweils über ein unteres Drehlager 24 und ein oberes Drehlager 25 zusammen, wobei diese Drehlager 24 und 25 nach Fig. 1 im Bereich des aufrechten Flügelholms 7 vorgesehen sind.The middle wing 5 interacts with the horizontal frame spars of the frame 2 each via a lower pivot bearing 24 and an upper pivot bearing 25, these pivot bearings 24 and 25 according to FIG. 1 being provided in the region of the upright wing spar 7.

Selbstverständlich wäre es auch möglich, die Drehlager 24 und 25 benachbart dem aufrechten Flügelholm 8 des Mittelflügels 5 vorzusehen.Of course, it would also be possible to provide the pivot bearings 24 and 25 adjacent to the upright wing spar 8 of the middle wing 5.

Aufbau und Wirkungsweise der zum unteren Drehlager 24 gehörenden Rahmen-Lagerhälfte 26 gehen aus de Fig. 2 bis 4 der Zeichnung hervor, während sich Aufbau und Wirkungsweise der Rahmen-Lagerhälfte 27 für das obere Drehlager den Fig. 5 bis 7 entnehmen lassen.The structure and mode of operation of the frame bearing half 26 belonging to the lower pivot bearing 24 are shown in FIGS. 2 to 4 of the drawing, while the structure and mode of operation of the frame bearing half 27 for the upper pivot bearing can be seen in FIGS. 5 to 7.

Aus Fig. 8 ergibt sich ein Detail, welches bei beiden Rahmen-Lagerhälften 26 und 27 übereinstimmend verwirklicht ist.8 shows a detail which is realized in the same way in both frame bearing halves 26 and 27.

Die Ausgestaltung der zu den Drehlagern 24 und 25 gehörenden Flügel-Lagerhälften 28 und 29 ist von üblicher Art. Daher sind die Flügel-Lagerhälften 28 und 29 lediglich schematisch und andeutungsweise -strichpunktiert- in den Fig. 1, 4 und 7 zu sehen.The design of the wing bearing halves 28 and 29 belonging to the pivot bearings 24 and 25 is of a conventional type. Therefore, the wing bearing halves 28 and 29 can only be seen schematically and indicated by dash-dotted lines in FIGS. 1, 4 and 7.

Die Rahmen-Lagerhälfte 26 des unteren Drehlagers 24 ist an der raumseitigen Stirnfläche des Blendrahmens 2, nämlich am unteren, horizontalen Rahmenholm 21 desselben, montiert, wie das den Fig. 2 und 3 entnommen werden kann. Hingegen ist es für die zugehörigen Flügel-Lagerhälfte 28 zweckmäßig, diese zumindest teilweise an der Umfangsfläche des Flügelüberschlags im Bereich einer Flügelecke zu befestigen.The frame bearing half 26 of the lower pivot bearing 24 is mounted on the room-side end face of the frame 2, namely on the lower, horizontal frame spar 21 of the same, as can be seen in FIGS. 2 and 3. On the other hand, it is expedient for the associated wing bearing half 28 to at least partially fasten it to the peripheral surface of the wing flap in the region of a wing corner.

Die Rahmen-Lagerhälfte 26 besteht aus einem Befestigungsteil 30 sowie einem hiervon getragenen Verstellteil 32, das parallel zur Blendrahmenebene über einen begrenzten Verschiebebereich justierbar ist und einen Lagerzapfen 34 trägt, mit dem die Flügel-Lagerhälfte 28 über eine Lagerbüchse oder Lageröffnung 36 in axialen Steckeingriff gebracht werden kann.The frame bearing half 26 consists of a fastening part 30 and an adjustment part 32 carried by it, which can be adjusted parallel to the frame level over a limited displacement range and carries a bearing journal 34 with which the wing bearing half 28 is brought into axial engagement via a bearing bush or bearing opening 36 can be.

Das Verstellteil 32 der Rahmen-Lagerhälfte 26 wird von einem in einer Ausnehmung oder einem Durchbruch 38 des Befestigungsteils 30 verschiebbar geführten und abgestützten Kulissenstein gebildet, an dem eine parallel zur Verschieberichtung verlaufende Schraubspindel 40 angreift. Diese Schraubspindel 40 hat dabei ihr Widerlager am Befestigungsteil 30 und weist an mindestens einem Ende einen von außen zugänglichen Eingriff 42, beispielsweise einen Innensechskant, für ein Verstellwerkzeug, vornehmlich einen Steckschlüssel, auf.The adjusting part 32 of the frame bearing half 26 is formed by a sliding block which is guided and supported in a recess or an opening 38 in the fastening part 30 and on which a screw spindle 40 which runs parallel to the direction of displacement acts. This screw spindle 40 has its abutment on the fastening part 30 and has at least one end an externally accessible engagement 42, for example a hexagon socket, for an adjusting tool, primarily a socket wrench.

Aus Fig. 2 der Zeichnung ist dabei ersichtlich, daß die Schraubspindel 40 einerseits drehbar und verschiebesicher im Befestigungsteil 30 lagert, während sie andererseits mit einem Gewindeabschnitt 44 des das Verstellteil 32 bildenden Kulissensteins in Eingriff steht.From Fig. 2 of the drawing it can be seen that the screw 40 is rotatably and securely mounted on the one hand in the fastening part 30, while on the other hand it is in engagement with a threaded portion 44 of the sliding block forming the adjusting part 32.

Möglich wäre es allerdings auch, die Schraubspindel 40 in mindestens einem Gewindeabschnitt des Befestigungsteils für schraubende Bewegung zu halten, während sie dann relativ zu dem das Verstellteil 32 bildenden Kulissenstein eine zwar drehbare, aber unverschiebliche Fixierung hat. Die drehbare, aber unverschiebliche Fixierung der Schraubspindel 40 relativ zum Verstellteil 32 kann beispielsweise durch einen in eine Umfangsnut der Schraubspindel eingerückten Sprengring oder Seegerring erhalten werden, der von einem Schlitz aufgenommen ist, welcher sich quer zur Längsachse der Schraubspindel 40 erstreckt und im Verstellteil 32 bzw. Kulissenstein vorgesehen ist.However, it would also be possible to hold the screw spindle 40 in at least one threaded section of the fastening part for screwing movement, while it then has a rotatable but non-displaceable fixation relative to the sliding block forming the adjusting part 32. The rotatable but non-displaceable fixation of the screw spindle 40 relative to the adjustment part 32 can be obtained, for example, by a snap ring or circlip which is inserted into a circumferential groove of the screw spindle and which is received by a slot which extends transversely to the longitudinal axis of the screw spindle 40 and in the adjustment part 32 or Sliding block is provided.

Beiden Funktionsarten der Schraubspindel 40 ist gemeinsam, daß eine Drehung derselben um ihre Längsachse eine Verschiebung des Verstellteils 32 innerhalb der Ausnehmung bzw. des Durchbruchs 38 des Befestigungsteils 30 bewirkt. Aus der in Fig. 2 gezeigten Mittelstellung des als Kulissenstein ausgeführten Verstellteils 32 kann dieses sowohl nach links als auch nach rechts praktisch stufenlos verlagert werden. Bei jeder möglichen Einstellung ist dabei das Verstellteil 32 bzw. der Kulissenstein formschlüssig gegenüber dem Befestigungsteil 30 fixiert.Both types of function of the screw spindle 40 have in common that a rotation of the same about their longitudinal axis causes a displacement of the adjusting part 32 within the recess or the opening 38 of the fastening part 30. From the central position shown in FIG. 2 of the adjusting part 32 designed as a sliding block, it can be shifted practically continuously both to the left and to the right. With each possible setting, the adjusting part 32 or the sliding block is fixed in a form-fitting manner with respect to the fastening part 30.

Während der Lagerzapfen 34 nahe dem vorderen Ende des als Verstellteil 32 dienenden Kulissensteins sitzt, greift die Schraubspindel 40 in der Nähe von dessen hinterem Ende an, wie das deutlich aus Fig. 2 ersichtlich ist.While the bearing pin 34 sits near the front end of the sliding block serving as the adjusting part 32, the screw spindle 40 engages near the rear end thereof, as can be clearly seen in FIG. 2.

Das vordere Ende des als Kulissenstein ausgebildeten Verstellteils 32 wird von einer Rippe bzw. einem Steg 46 am Befestigungsteil 30 untergriffen und/oder abgestützt, wobei diese Rippe bzw. dieser Steg in eine Abstufung 48 eingreift, die sich am vorderen Ende des das Verstellteil 32 bildenden Kulissensteins befindet (Fig. 8).The front end of the adjusting part 32, which is designed as a sliding block, is gripped and / or supported by a rib or a web 46 on the fastening part 30, this rib or this web engaging in a step 48 that forms at the front end of the adjusting part 32 The sliding block is located (Fig. 8).

Die Rippe bzw. der Steg 46 befindet sich in der Ausnehmung bzw. im Durchbruch 38 des Befestigungsteils 30 an dem vom Blendrahmen 2 abgewendeten Ende. Andererseits hat der das Verstellteil 32 bildende Kulissenstein an seinem hinderen Ende eine zur Längsachse der Schraubspindel 40 parallele, jedoch normal zu seiner Hauptebene ausgerichtete Fläche 50, die sich an einer zugeordneten Widerlagerfläche 52 des Befestigungsteils 30 abstützt.The rib or the web 46 is located in the recess or in the opening 38 of the fastening part 30 at the end facing away from the frame 2. On the other hand, the sliding block forming the adjusting part 32 has at its rear end a surface 50 which is parallel to the longitudinal axis of the screw spindle 40 but is oriented normally to its main plane and which is supported on an associated abutment surface 52 of the fastening part 30.

Das Befestigungsteil 30 der Rahmen-Lagerhälfte 26 für das untere Drehlager 24 weist rückseitig vorspringende Tragzapfen 54 auf, die in dazu passende Bohrungen am Rahmenholm 21 des Blendrahmens 2 eingeschoben werden können. Sodann erfolgt die Festlegung der Rahmen-Lagerhälfte 26 am Blendrahmen 2 durch Schrauben, welche in Senklöcher 56 des Befestigungsteils 30 zum Eingriff gelangen.The fastening part 30 of the frame bearing half 26 for the lower pivot bearing 24 has projecting support pins 54 on the rear, which can be inserted into matching bores on the frame spar 21 of the frame 2. Then the frame bearing half 26 is fixed to the frame 2 by screws which engage in countersunk holes 56 in the fastening part 30.

Erwähnt sei hier noch, daß der Lagerzapfen 34 unterhalb eines angeformten Stützbundes 58 mit einem koaxialen Gewindeansatz 60 versehen werden kann, der mit einem Innengewinde in dem als Kulissenstein ausgeführten Verstellteil 32 stufenlos höhenjustierbar zusammenwirkt. Gewindeansatz 60 und Innengewinde 62 stehen vorzugsweise schwergängig verdrehbar miteinander in Eingriff, während der Lagerzapfen 34 stirnseitig -oben- einen Werkzeugeingriff 64, beispielsweise einen Innensechskant, enthält. Auf die beschriebene Art und Weise erhält der Lagerzapfen 34 mit seinem Stützbund 58 eine höhenjustierbare Anordnung in dem als Kulissenstein ausgeführten Verstellteil 32.It should also be mentioned here that the bearing pin 34 can be provided below a molded support collar 58 with a coaxial threaded shoulder 60 which interacts with an internal thread in the adjusting part 32, which is designed as a sliding block, and is continuously adjustable in height. Threaded shoulder 60 and internal thread 62 are preferably rotatably engaged with one another, while the bearing journal 34 contains a tool engagement 64, for example an internal hexagon, on the front side. In the manner described, the bearing journal 34, with its support collar 58, has a height-adjustable arrangement in the adjustment part 32 designed as a sliding block.

Die Rahmen-Lagerhälfte 27 des oberen Drehlagers 25 ist an der raumseitigen Stirnfläche des Blendrahmens 2 am oberen, horizontalen Rahmenholm 20 desselben, montiert, wie das den Fig. 5 und 6 entnommen werden kann. Hingegen ist es für die zugehörigen Flügel-Lagerhälfte 29 zweckmäßig, diese zumindest teilweise an der Umfangsfläche des Flügelüberschlags im Bereich einer Flügelecke zu befestigen.The frame bearing half 27 of the upper pivot bearing 25 is mounted on the room-side end face of the frame 2 on the upper, horizontal frame spar 20 of the same, as can be seen in FIGS. 5 and 6. On the other hand, it is expedient for the associated wing bearing half 29 to at least partially fasten it to the peripheral surface of the wing flap in the area of a wing corner.

Die Rahmen-Lagerhälfte 27 besteht aus einem Befestigungsteil 31 sowie einem hiervon getragenen Verstellteil 33, das parallel zur Blendrahmenebene über einen begrenzten Verschiebebereich justierbar ist und eine Lagerbüchse 37 enthält, mit der die Flügel-Lagerhälfte 29 über einen Lagerzapfen 35 in axialen Steckeingriff gebracht werden kann.The frame bearing half 27 consists of a fastening part 31 and an adjustment part 33 carried by it, which is adjustable parallel to the frame level over a limited displacement range and contains a bearing bush 37 with which the wing bearing half 29 can be brought into axial engagement via a bearing pin 35 .

Das Verstellteil 33 der Rahmen-Lagerhälfte 27 wird von einem in einer Ausnehmung oder einem Durchbruch 39 des Befestigungsteils 31 verschiebbar geführten und abgestützten Kulissenstein gebildet, an dem eine parallel zur Verschieberichtung verlaufende Schraubspindel 41 angreift. Diese Schraubspindel 41 hat dabei ihr Widerlager am Befestigungsteil 31 und weist an mindestens einem Ende einen von außen zugänglichen Eingriff 43, beispielsweise einen Innensechskant, für ein Verstellwerkzeug, vornehmlich einen Steckschlüssel, auf.The adjustment part 33 of the frame bearing half 27 is formed by a sliding block which is guided and supported in a recess or an opening 39 in the fastening part 31 and on which a screw spindle 41, which runs parallel to the direction of displacement, engages. This screw spindle 41 has its abutment on the fastening part 31 and has at least one end an externally accessible engagement 43, for example a hexagon socket, for an adjusting tool, primarily a socket wrench.

Aus Fig. 5 der Zeichnung ist dabei ersichtlich, daß die Schraubspindel 41 einerseits drehbar und verschiebesicher im Befestigungsteil 31 lagert, während sie andererseits mit einem Gewindeabschnitt 45 des das Verstellteil 33 bildenden Kulissensteins in Eingriff steht.From Fig. 5 of the drawing it can be seen that the screw 41 is rotatably and securely mounted on the one hand in the fastening part 31, while on the other hand it is in engagement with a threaded portion 45 of the sliding block forming the adjusting part 33.

Möglich wäre es allerdings auch, die Schraubspindel 41 in mindestens einem Gewindeabschnitt des Befestigungsteils für schraubende Bewegung zu halten, während sie dann relativ zu dem das Verstellteil 33 bildenden Kulissenstein eine zwar drehbare, aber unverschiebliche Fixierung hat. Die drehbare, aber unverschiebliche Fixierung der Schraubspindel 41 relativ zum Verstellteil 33 kann beispielsweise durch einen in eine Umfangsnut der Schraubspindel 41 eingerückten Sprengring oder Seegerring erhalten werden, der von einem Schlitz aufgenommen ist, welcher sich quer zur Längsachse der Schraubspindel 41 erstreckt und im Verstellteil 33 bzw. Kulissenstein vorgesehen ist.However, it would also be possible to hold the screw spindle 41 in at least one threaded section of the fastening part for screwing movement, while it then has a rotatable but non-displaceable fixation relative to the sliding block forming the adjusting part 33. The rotatable but immovable fixation of the screw spindle 41 relative to the adjustment part 33 can be obtained, for example, by a snap ring or circlip inserted into a circumferential groove of the screw spindle 41, which is received by a slot which extends transversely to the longitudinal axis of the screw spindle 41 and is provided in the adjusting part 33 or sliding block.

Beiden Funktionsarten der Schraubspindel 41 ist gemeinsam, daß eine Drehung derselben um ihre Längsachse eine Verschiebung des Verstellteils 33 innerhalb der Ausnehmung bzw. des Durchbruchs 39 des Befestigungsteils 31 bewirkt. Aus der in Fig. 5 gezeigten Mittelstellung des als Kulissenstein ausgeführten Verstellteils 33 kann dieses sowohl nach links als auch nach rechts praktisch stufenlos verlagert werden. Bei jeder möglichen Einstellung ist dabei das Verstellteil 33 bzw. der Kulissenstein formschlüssig gegenüber dem Befestigungsteil 31 fixiert.Both types of function of the screw spindle 41 have in common that a rotation of the screw spindle about its longitudinal axis causes a displacement of the adjusting part 33 within the recess or the opening 39 of the fastening part 31. From the central position shown in FIG. 5 of the adjusting part 33 designed as a sliding block, it can be shifted practically continuously both to the left and to the right. With each possible setting, the adjusting part 33 or the sliding block is fixed in a form-fitting manner with respect to the fastening part 31.

Während die Lagerbüchs 37 nahe dem vorderen Ende des als Verstellteil 33 dienenden Kulissensteins sitzt, greift die Schraubspindel 41 in der Nähe von dessen hinterem Ende an, wie das deutlich aus Fig. 5 ersichtlich ist.While the bearing bush 37 sits near the front end of the sliding block serving as the adjusting part 33, the screw spindle 41 engages near its rear end, as can be clearly seen in FIG. 5.

Das vordere Ende des als Kulissenstein ausgebildeten Verstellteils 33 wird von einer Rippe bzw. einem Steg 46 am Befestigungsteil 31 untergriffen und/oder abgestützt, wobei diese Rippe bzw. dieser Steg in eine Abstufung 48 eingreift, die sich am vorderen Ende des das Verstellteil 33 bildenden Kulissensteins befindet (Fig. 8).The front end of the adjusting part 33 designed as a sliding block is gripped and / or supported by a rib or a web 46 on the fastening part 31, this rib or this web engaging in a step 48 which forms at the front end of the adjusting part 33 The sliding block is located (Fig. 8).

Die Rippe bzw. der Steg 47 befindet sich in der Ausnehmung bzw. im Durchbruch 39 des Befestigungsteils 31 an dem vom Blendrahmen 2 abgewendeten Ende. Andererseits hat der das Verstellteil 33 bildende Kulissenstein an seinem hinderen Ende eine zur Längsachse der Schraubspindel 41 parallele, jedoch normal zu seiner Hauptebene ausgerichtete Fläche 51, die sich an einer zugeordneten Widerlagerfläche 53 des Befestigungsteils 31 abstützt.The rib or the web 47 is located in the recess or in the opening 39 of the fastening part 31 at the end facing away from the frame 2. On the other hand, the sliding block forming the adjusting part 33 has at its rear end a surface 51 which is parallel to the longitudinal axis of the screw spindle 41 but is oriented normally to its main plane and which is supported on an associated abutment surface 53 of the fastening part 31.

Das Befestigungsteil 31 der Rahmen-Lagerhälfte 27 für das obere Drehlager 25 weist rückseitig vorspringende Tragzapfen 55 auf, die in dazu passende Bohrungen am Rahmenholm 20 des Blendrahmens 2 eingeschoben werden können. Sodann erfolgt die Festlegung der Rahmen-Lagerhälfte 27 am Blendrahmen 2 durch Schrauben, welche in Senklöcher 57 des Befestigungsteils 31 zum Eingriff gelangen.The fastening part 31 of the frame bearing half 27 for the upper pivot bearing 25 has projecting support pins 55 on the rear, which can be inserted into matching bores on the frame spar 20 of the frame 2. Then the frame bearing half 27 is fixed to the frame 2 by screws which engage in countersunk holes 57 in the fastening part 31.
