Abstract

The bearing casing has an edge-open recess (16) in which a brake ring at least partly engaging around the bearing pin (3) and a drive pressing the brake ring on the bearing pin are provided. The drive is operable from outside the bearing casing. The brake ring and the drive are successively radially insertable in the recess. The recess is closable by a cover plate. The drive is a brake wedge which on operation causes a displacement or deformation of the brake ring. The adjustment path of the brake wedge occurs in a tangential direction to the bearing pin axis. An adjustment screw penetrates the brake wedge and supports in the recess.

Description

Die Erfindung betrifft ein Lager für einen zumindest drehbaren Flügel eines Fensters, einer Tür o.dgl. mit einem Rahmen-Lagerteil und einem Flügel-Lagerteil, von denen eines einen Lagerzapfen und das andere eine Lagerhülse mit Lagerbohrung aufweist.The invention relates to a bearing for an at least rotatable wing of a window, a door or the like. with a frame bearing part and a wing bearing part, one of which has a bearing journal and the other has a bearing sleeve with a bearing bore.

Lager dieser Art sind schon lange und in verschiedensten Ausführungen bekannt. Moderne Ausführungen sind sehr leichtgängig, was jedoch den Nebeneffekt hat, daß dann, wenn der Flügel nicht genau im Lot eingebaut wird, dies zu einer unerwünschten Flügelbewegung eines ganz oder teilweise geöffneten Flügels gegenüber dem festen Rahmen führen kann.Bearings of this type have been known for a long time and in various designs. Modern designs are very smooth, but this has the side effect that if the sash is not installed exactly in the plumb line, this can lead to an undesired sash movement of a fully or partially opened sash relative to the fixed frame.

Aus der US-A-4 964 193 ist ein Drehlager bekannt, bei dem zwischen den Scharnierhülsen und der Scharnierachse eine rohrförmige Hülse aus gleitfähigem Material eingesetzt ist, das bei zunehmenden Druck Bremskräfte entwickelt. Auf diese Weise soll eine Bremsung des Flügels bewirkt werden, so daß dieser nicht mehr durch das Eigengewicht oder durch Luftzug verschwenkt wird.From US-A-4 964 193 a pivot bearing is known, in which a tubular sleeve made of slidable material is used between the hinge sleeves and the hinge axis, which develops braking forces with increasing pressure. In this way, braking of the wing is to be effected so that it is no longer pivoted by its own weight or by drafts.

Ferner ist aus der US-A-4 490 884 ein gebremstes Drehlager bekannt. Dieses Drehlager ist vor allem für die Verwendung von Eingangstüren vorgesehen, wobei die Bremskraft einstellbar sein soll und unabhängig von der Anzahl der erreichten Öffnungszyklen die eingestellte Bremskraft konstant bleiben soll.Furthermore, a braked rotary bearing is known from US-A-4 490 884. This pivot bearing is primarily intended for the use of entrance doors, the braking force should be adjustable and the set braking force should remain constant regardless of the number of opening cycles achieved.

Als weiterer Stand der Technik ist aus der DE-A-14 59 042 ein Schwingflügellager bekannt geworden, das mit einer definiert einstellbaren Bremsvorrichtung versehen ist. Dieses Schwingflügellager ist jedoch von seinen baulichen Dimensionen her nicht für Drehflügel bzw. Drehkippflügel verwendbar.As a further prior art, a swing-wing bearing has become known from DE-A-14 59 042, which is provided with a defined adjustable braking device. In terms of its structural dimensions, however, this oscillating-wing bearing cannot be used for rotating sashes or tilt-and-turn sashes.

Aus der EP-A-258 639 ist eine nachrüstbare Bremsvorrichtung für solche Drehkipp-Fenster oder -Türen bekannt geworden, bei denen sich der Bedarf erst nach dem Einbau des Fensters bzw. der Tür in das Gebäude abzeichnet. Diese Bremsvorrichtung stellt ein separat zu montierendes Nachrüstteil dar, es ist aufwendig und teuer und stört das Design des Fensters bzw. der Tür.EP-A-258 639 has disclosed a retrofittable braking device for tilt-turn windows or doors in which the need only becomes apparent after the window or door has been installed in the building. This braking device is a separately assembled Retrofit part, it is complex and expensive and disturbs the design of the window or door.

Aus der EP-A-215 281 ist ein Flügel lager mit einstellbarer Bremsvorrichtung bekannt geworden, mit der eine unerwünschte Leichtgängigkeit des Flügellagers eliminiert werden kann. Hierzu ist am Lager eine Klemmschraube vorgesehen, mittels welcher eine den Lagerzapfen umgreifende Klemmhülse auf die gewünschte Bremskraft eingestellt werden kann. Hierzu weist die Klemmhülse einen Vertikalschlitz auf, der eigens zur Realisierung der Verstellmöglichkeit in die Klemmhülse eingefräst oder eingesägt werden muß. Außerdem muß die Klemmhülse mit einem Gewinde für die Klemmschraube versehen werden. Da die Klemmhülse Teil der den Lagerzapfen aufnehmenden Lagerhülse ist, muß der elastische Abschnitt der Klemmhülse noch über einen Horizontalschlitz vom Rest der Lagerhülse abgesetzt werden. Sowohl die Schlitze als auch das Gewinde sind relativ aufwendig, da eine Durchführung der Arbeitsgänge zu deren Herstellung an Bearbeitungsmaschinen mit automatischer Teilezufuhr sehr schwer möglich ist.From EP-A-215 281 a wing bearing with adjustable braking device has become known, with which an undesired smooth operation of the wing bearing can be eliminated. For this purpose, a clamping screw is provided on the bearing, by means of which a clamping sleeve encompassing the bearing journal can be set to the desired braking force. For this purpose, the clamping sleeve has a vertical slot, which has to be milled or sawed into the clamping sleeve specifically to realize the adjustment possibility. In addition, the clamping sleeve must be provided with a thread for the clamping screw. Since the clamping sleeve is part of the bearing sleeve receiving the journal, the elastic section of the clamping sleeve must still be separated from the rest of the bearing sleeve via a horizontal slot. Both the slots and the thread are relatively complex, since it is very difficult to carry out the operations for their production on processing machines with automatic parts feed.

Ausgehend von der EP-A-215 281 liegt der Erfindung die Aufgabe zugrunde, ein Lager der eingangs genannten Art so weiterzubilden, daß die Bremskraft zwischen Lagerzapfen und Lagerhülse einfach einstellbar ist, wobei jedoch die Herstellung des Lagers kostengünstig und einfach durchführbar sein soll.Starting from EP-A-215 281, the invention has for its object to develop a bearing of the type mentioned so that the braking force between the journal and bearing sleeve is easily adjustable, but the Production of the bearing should be inexpensive and easy to carry out.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Lagerhülse mit einer randoffenen Ausnehmung versehen ist, daß in der Ausnehmung ein den Lagerzapfen wenigstens teilweise umgreifender Bremsring und ein den Bremsring an den Lagerzapfen pressender Antrieb vorgesehen sind.This object is achieved in that the bearing sleeve is provided with an open-edged recess that a brake ring at least partially encompassing the bearing pin and a drive pressing the brake ring on the bearing pin are provided in the recess.

Die Herstellung des erfindungsgemäßen Lagers, insbesondere der Lagerhülse ist wesentlich einfacher als beim bekannten Stand der Technik, da die randoffene Ausnehmung bereits in der Gußform als Tasche berücksichtigt werden kann. Es bedarf keiner Schlitze für ein Klemmelement. Das am Lagerzapfen angreifende bremsende Element wird von einem Bremsring gebildet, der in die randoffene Ausnehmung eingesetzt wird. Dieser Bremsring ist ein separat hergestelltes Bauteil aus Zinkdruckguß oder vorzugsweise aus Kunststoff (z.B. Polyamid o.dgl.). Der Andruckvorgang des Bremsrings an den Lagerzapfen erfolgt über einen Antrieb, der sich ebenfalls in der Ausnehmung befindet. Beim erfindungsgemäßen Lager sind demnach alle für die Bremsung des Lagerzapfens erforderlichen Bauteile in der Ausnehmung angeordnet. Sie stören also weder das Design des Lagers noch dessen Funktion.The manufacture of the bearing according to the invention, in particular the bearing sleeve, is considerably simpler than in the known prior art, since the open-edged recess can already be taken into account as a pocket in the casting mold. No slots are required for a clamping element. The braking element which engages the journal is formed by a brake ring which is inserted into the recess which is open at the edge. This brake ring is a separately manufactured component made of die-cast zinc or preferably made of plastic (eg polyamide or the like). The brake ring is pressed onto the bearing journal by a drive, which is also located in the recess. In the bearing according to the invention, all the components required for braking the bearing journal are accordingly arranged in the recess. So you do not interfere with the design of the bearing or its function.

Bei einer Weiterbildung ist vorgesehen, daß der Antrieb von außerhalb der Lagerhülse betätigbar ist. Auf diese Weise kann bequem nach der kompletten Montage des Flügels die Bremskraft eingestellt werden, bzw. kann die Bremskraft erforderlichenfalls zu einem späteren Zeitpunkt erhöht bzw. verringert werden. Dies kann ohne Demontage des Lagers und somit auch von nicht spezialisierten Personen durchgeführt werden.In a further development it is provided that the drive can be actuated from outside the bearing sleeve. In this way, the braking force can be conveniently adjusted after the complete assembly of the wing, or the braking force can be increased or decreased at a later time if necessary. This can be done without dismantling the bearing and therefore also by non-specialized people.

Gemäß einer bevorzugten Ausführungsform sind der Bremsring und der Antrieb, insbesondere in dieser Reihenfolge radial in die sacklochartig ausgebildete Ausnehmung einschiebbar. Hierfür bildet die Ausnehmung eine an der Innenoberfläche der Lagerhülse vorgesehene Umfangsnut, in die sowohl der Bremsring als auch der Antrieb eingeschoben werden. Über die Nut werden diese Bauteile axial sicher gehalten. Dabei ist die randseitige Öffnung der Ausnehmung insbesondere über ein Abdeckblech o.dgl. verschließbar. Dieses Abdeckblech kann angeschraubt, angenietet oder auf entsprechende Weise an der Außenseite der Lagerhülse über der Öffnung befestigt werden.According to a preferred embodiment, the brake ring and the drive, particularly in this order, can be inserted radially into the blind hole-like recess. For this purpose, the recess forms a circumferential groove provided on the inner surface of the bearing sleeve, into which both the brake ring and the drive are inserted. These components are held axially securely via the groove. The edge opening of the recess or the like is in particular via a cover plate. lockable. This cover plate can be screwed on, riveted on or attached in a corresponding manner to the outside of the bearing sleeve above the opening.

Bei einer bevorzugten Ausführungsform ist vorgesehen, daß der Antrieb ein Bremskeil ist. Dabei verursacht der Bremskeil bei Betätigung eine radiale Verlagerung oder Deformation des Bremsringes in Richtung auf den Lagerzapfen.In a preferred embodiment it is provided that the drive is a brake wedge. When actuated, the brake wedge causes a radial displacement or deformation of the brake ring in the direction of the bearing journal.

Anstelle eines Bremskeils kann jedoch auch eine Exzenterschraube o.dgl. Einsatz finden.Instead of a brake wedge, however, an eccentric screw or the like can also be used. Find use.

Der Verstellweg des Bremskeils erfolgt bevorzugt im wesentlichen in tangentialer Richtung zur Lagerzapfenachse. Dabei zeigt die Keilfläche in radialer Richtung, wodurch der Bremsring betätigt, d.h. verlagert oder verformt wird, insbesondere an den Lagerzapfen gepreßt wird.The adjustment of the brake wedge is preferably essentially in the tangential direction to the journal axis. The wedge surface points in the radial direction, whereby the brake ring is actuated, i.e. is shifted or deformed, in particular is pressed on the bearing journal.

Bei einem bevorzugten Ausführungsbeispiel ist der Bremskeil von einer Stellschraube durchsetzt, die sich in der Ausnehmung abstützt. Durch Verstellung der Stellschraube wird der Bremskeil verstellt, wobei die Stellschraube bevorzugt in den Bremskeil eingeschraubt ist. Der Bremskeil besteht vorzugsweise aus Zinkdruckguß und bietet dadurch einen guten Halt für die Schraube. Er kann aber auch aus Kunststoff, z.B. Polyamid bestehen.In a preferred embodiment, the brake wedge is penetrated by an adjusting screw, which is supported in the recess. The brake wedge is adjusted by adjusting the adjusting screw, the adjusting screw preferably being screwed into the brake wedge. The brake wedge is preferably made of die-cast zinc and therefore offers a good hold for the screw. But it can also be made of plastic, e.g. Polyamide exist.

Bei einer Weiterbildung ist vorgesehen, daß der Kopf der Stellschraube durch eine Öffnung, deren Querschnitt kleiner ist als der Durchmesser des Kopfes, von außen zugänglich ist. Diese Konstruktion erlaubt eine Abstützung des Kopfes der Schraube an der Innenfläche der Ausnehmung, wobei aber eine Betätigung der Schraube dennoch von außen möglich ist. Das andere Ende der Schraube stützt sich an der gegenüberliegenden Seite der Ausnehmung ab, was wichtig für das Lösen der Bremse ist. Der Bremskeil kann somit auf dem Gewinde der Schraube entlangfahren.In a further development it is provided that the head of the set screw is accessible from the outside through an opening, the cross section of which is smaller than the diameter of the head. This construction allows the head of the screw to be supported on the inner surface of the recess, but actuation of the screw is nevertheless possible from the outside. The other end of the screw is supported on the opposite side of the recess, which is important for the brake is released. The brake wedge can thus travel along the thread of the screw.

Bevorzugt weist der Bremsring eine zur Keilfläche des Bremskeils kongruente Schrägfläche auf. Auf diese Weise wird der Bremsring in jeder Stellung des Bremskeils optimal an den Lagerzapfen angepreßt.The brake ring preferably has an inclined surface congruent to the wedge surface of the brake wedge. In this way, the brake ring is optimally pressed against the bearing journal in every position of the brake wedge.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel handelt es sich um ein Dreh-Kipp-Lager mit einem Flügel-Lagerteil 1 und einem Rahmen-Lagerteil 10, wobei das Rahmen-Lagerteil (10) in herkömmlicher Weise ausgebildet ist. Das Flügel-Lagerteil 1 weist eine Lagerhülse 2 auf, in deren Lagerbohrung 13 ein schwenkbar gelagerter Lagerzapfen 3, der insbesondere aus Stahl besteht, von unten her eingreift. Dieser Lagerzapfen 3 ist über ein Kipplager 12 schwenkbar am Rahmen-Lagerteil 10 befestigt. Demnach ist der nicht dargestellte Flügel eines Fenster oder einer Tür o.dgl. im Sinne des Doppelpfeils 4 um die geometrische Achse 5 des Lagerzapfens 3 drehbar und in Richtung des Pfeils 6 in eine Kippstellung überführbar. Die geometrische Zapfenachse 5 ist zugleich auch die geometrische Achse der Lagerbohrung 13 bzw. die Drehachse der Lagerhülse 2.The embodiment shown in the drawing is a turn-tilt bearing with a wing bearing part 1 and a frame bearing part 10, wherein the frame bearing part (10) is designed in a conventional manner. The wing bearing part 1 has a bearing sleeve 2, in the bearing bore 13 of which a pivotally mounted bearing journal 3, which consists in particular of steel, engages from below. This journal 3 is pivotally attached to the frame bearing part 10 via a tilting bearing 12. Accordingly, the wing of a window or a door, not shown, or the like. in the sense of the double arrow 4 rotatable about the geometric axis 5 of the bearing journal 3 and can be converted into a tilting position in the direction of the arrow 6. The geometric journal axis 5 is also the geometric axis of the bearing bore 13 or the axis of rotation of the bearing sleeve 2.

Das erfindungsgemäße Lager dient insbesondere zum Lagern eines Flügels, eines Fensters oder einer Tür an einem Blendrahmen. Infolgedessen ist das Lager als verstärkte Ausführung mit Tragwinkeln 8 und 9 ausgebildet. Außerdem bildet das Gehäuse 7 einen weiteren Tragwinkel 11, der ebenfalls am Flügelrahmen befestigt wird. Hierfür dient eine Bohrung 14 am oberen Ende des Tragwinkels 11. Weitere Befestigungsbohrungen sind an den beiden Tragwinkeln 8 und 9 vorgesehen.The bearing according to the invention is used in particular for storing a wing, a window or a door on a frame. As a result, the bearing is designed as a reinforced version with support brackets 8 and 9. In addition, the housing 7 forms a further support bracket 11, which is also attached to the casement. A hole 14 at the upper end of the support bracket 11 is used for this purpose. Additional mounting holes are provided on the two support brackets 8 and 9.

Das untere Ende des Gehäuses 7 wird von einem winkel- oder bogenförmigen Lageransatz 15 gebildet, an welchem die beiden Tragwinkel 8 und 9 befestigt insbesondere angenietet sind.The lower end of the housing 7 is formed by an angular or arcuate bearing projection 15, to which the two support brackets 8 and 9 are attached, in particular riveted.

Orthogonal zu diesem Lageransatz 15 erstreckt sich die Lagerhülse 2.The bearing sleeve 2 extends orthogonally to this bearing projection 15.

Diese Lagerhülse 2 weist eine Ausnehmung 16 auf, die randoffen ist. Die Öffnung 17 weist dabei in Richtung des Flügels, d.h. in der Figur 2 nach links. Diese Ausnehmung 16 wird bereits beim Gießen der Lagerhülse 2 hergestellt und weist die Form einer Tasche auf. Sie wird von einer Innenumfangsnut 18 gebildet, in die ein Bremsring 19 und ein als Antrieb 20 dienender Bremskeil 21 radial, d.h. von der Öffnung 17 her, einschiebbar sind. Dabei wird zuerst der Bremsring 19 eingeschoben, und der Bremskeil 21 auf den Bremsring 19 aufgesetzt. Der Bremsring 19 weist eine Bohrung 22 auf, die im wesentlichen dem Durchmesser des Lagerzapfens 3 entspricht. Außerdem ist der Bremsring 19 mit einem Vertikalschlitz 23 versehen. An der dem Bremskeil 21 zugewandten Seite weist der Bremsring 19 eine Schrägfläche 24 auf, über die er am Bremskeil 21 bzw. an dessen Keilfläche 25 anliegt. Die der Keilfläche 25 gegenüberliegende Seite des Bremskeils 21 stützt sich an einem Abdeckblech 26 ab, welches mit der Lagerhülse 2 verschraubt oder vernietet ist.This bearing sleeve 2 has a recess 16 which is open at the edge. The opening 17 faces in the direction of the wing, i.e. to the left in FIG. 2. This recess 16 is already produced when the bearing sleeve 2 is cast and has the shape of a pocket. It is formed by an inner circumferential groove 18 into which a brake ring 19 and a brake wedge 21 serving as a drive 20 radially, i.e. are insertable from the opening 17. First, the brake ring 19 is inserted, and the brake wedge 21 is placed on the brake ring 19. The brake ring 19 has a bore 22 which corresponds essentially to the diameter of the bearing journal 3. In addition, the brake ring 19 is provided with a vertical slot 23. On the side facing the brake wedge 21, the brake ring 19 has an inclined surface 24, via which it rests on the brake wedge 21 or on its wedge surface 25. The side of the brake wedge 21 opposite the wedge surface 25 is supported on a cover plate 26 which is screwed or riveted to the bearing sleeve 2.

Der Bremskeil 21 ist von einer Stellschraube 27 durchsetzt, die in ein entsprechendes Gewinde des aus Zinkdruckguß bestehenden Bremskeils 21 eingeschraubt ist. Die Länge der Stellschraube 27 entspricht dabei dem Abstand der einander zugewandten Innenflächen der vertikalen Wände der Ausnehmung 16. Auf diese Weise wird die Stellschraube 27 in Richtung deren Achse 28 im wesentlichen spielfrei gehalten, und es liegt eine hinreichende Reibung gegen selbsttätiges Verstellen vor. In der Achse 28 der Stellschraube 27 ist die Lagerhülse 2 mit einer Bohrung 29 versehen, deren Bohrungsdurchmesser geringer ist als der Durchmesser des Schraubenkopfes 30. Auf diese Weise kann die Stellschraube 27 von außen z.B. mit einem Schraubendreher betätigt werden, wobei sie jedoch verliersicher gehalten wird.The brake wedge 21 is penetrated by an adjusting screw 27 which is screwed into a corresponding thread of the brake wedge 21 made of die-cast zinc. The length of the set screw 27 corresponds to the distance between each other facing inner surfaces of the vertical walls of the recess 16. In this way, the set screw 27 is kept substantially free of play in the direction of the axis 28 thereof, and there is sufficient friction against automatic adjustment. In the axis 28 of the adjusting screw 27, the bearing sleeve 2 is provided with a bore 29, the bore diameter of which is smaller than the diameter of the screw head 30. In this way, the adjusting screw 27 can be actuated from the outside, for example with a screwdriver, but it is held captively .

Beim Betätigen der Stellschraube 27 wird der Bremskeil 21 in Richtung der Achse 28 verlagert und drückt dabei über die Keilfläche 25 auf die Schrägfläche 24 des Bremsrings 19 und preßt diesen auf die Umfangsfläche des Lagerzapfens 3. Auf diese Weise wird im Bereich des Bremsrings 19 die Reibung am Lagerzapfen 3 erhöht, wodurch die Leichtgängigkeit des Lagerzapfens 3 in der Lagerbohrung 13 der Lagerhülse 2 gezielt reduziert wird.When the adjusting screw 27 is actuated, the brake wedge 21 is displaced in the direction of the axis 28 and presses on the wedge surface 25 onto the inclined surface 24 of the brake ring 19 and presses it onto the circumferential surface of the bearing journal 3. In this way, the friction in the area of the brake ring 19 becomes increased on the bearing journal 3, whereby the smooth running of the bearing journal 3 in the bearing bore 13 of the bearing sleeve 2 is specifically reduced.

Aus Figur 3 ist erkenntlich, daß die Bohrung 29 an der Lagerhülse 2 an der dem Betrachter des Flügel-Lagerteils 1 abgewandten Seite vorgesehen ist, so daß die Optik bzw. das Design des Lagers durch diese Bohrung 29 nicht gestört wird.From Figure 3 it can be seen that the bore 29 is provided on the bearing sleeve 2 on the side facing away from the viewer of the wing bearing part 1, so that the optics or the design of the bearing is not disturbed by this bore 29.

In Figur 2 ist außerdem ein Höhenverstellmechanismus für das Flügel-Lagerteil 1 auf dem Lagerzapfen 3 andeutungsweise dargestellt. Dieser Mechanismus weist eine Höheneinstellschraube 31 auf, die auf eine Lagerbuchse 32 wirkt. Diese Lagerbuchse 32 sitzt auf dem freien Ende des Lagerzapfens 3 auf. Um die Lagerbuchse 32 in Drehrichtung des Lagerzapfens 3 in der Lagerhülse 2 zu arretieren, weist die Lagerbuchse 32 eine radial vorstehende Nase auf, die in eine Längsnut in der Lagerhülse 2 eingreift. Auf diese Weise werden die Relativbewegungen des Lagerzapfens 3 bezüglich der Lagerhülse 2 nicht auf die Lagerbuchse 32 übertragen, so daß die Höheneinstellschraube 31 nicht ungewollt verstellt wird.In Figure 2, a height adjustment mechanism for the wing bearing part 1 on the journal 3 is also indicated shown. This mechanism has a height adjustment screw 31 which acts on a bearing bush 32. This bearing bush 32 sits on the free end of the journal 3. In order to lock the bearing bush 32 in the direction of rotation of the bearing journal 3 in the bearing sleeve 2, the bearing bush 32 has a radially projecting nose which engages in a longitudinal groove in the bearing sleeve 2. In this way, the relative movements of the journal 3 with respect to the bearing sleeve 2 are not transmitted to the bearing bush 32, so that the height adjustment screw 31 is not inadvertently adjusted.

In der Figur 4 ist eine Einstellvorrichtung für die Ausrichtung des Lagerzapfens 3 in der Lagerhülse 2 dargestellt. Diese Vorrichtung weist eine Einstellschraube 33 auf, die über einen Teil ihrer Länge mit einer Eindrehung 34 versehen ist. Die Einstellschraube 33 ist an ihrer Außenseite, insbesondere im Bereich der Enden mit einem Gewinde versehen und in eine Gewindebohrung in der Lagerhülse 2 eingeschraubt. Außerdem ist die Lagerhülse 2 mit einem Langloch 35 zur Aufnahme des Lagerzapfens 3 versehen. Wird der Lagerzapfen 3 in die Lagerhülse 2 eingeschoben, dann liegt der Lagerzapfen 3 am Grund der Eindrehung 33 sowie an der gegenüberliegenden Fläche des Langlochs 35 an. Beim Betätigen der Einstellschraube 33 wird der Lagerzapfen 3 durch die Eindrehung 34 mitgenommen und im Langloch 35 in Richtung dessen großer Halbachse bewegt. Auf diese Weise kann der Andruck des geschlossenen Flügels gegen den Blendrahmen eingestellt werden.FIG. 4 shows an adjusting device for the alignment of the bearing journal 3 in the bearing sleeve 2. This device has an adjusting screw 33 which is provided with a recess 34 over part of its length. The adjusting screw 33 is provided on its outside, in particular in the area of the ends, with a thread and screwed into a threaded bore in the bearing sleeve 2. In addition, the bearing sleeve 2 is provided with an elongated hole 35 for receiving the journal 3. If the bearing journal 3 is inserted into the bearing sleeve 2, then the bearing journal 3 rests on the bottom of the recess 33 and on the opposite surface of the elongated hole 35. When the adjusting screw 33 is actuated, the bearing journal 3 is taken along by the recess 34 and moved in the elongated hole 35 in the direction of its large semi-axis. On in this way the pressure of the closed wing against the frame can be adjusted.
