Definitions

  • the invention relates to a swinging wing bearing with a frame bearing part and a wing bearing part and a rocker arm connecting both, one end of which is rotatably supported on the frame bearing part and the other end on the wing bearing part about a first and subsequently or simultaneously about a second axis of rotation, the end facing away from the room of the bearing is closed at its lower end in the installed position by a lower cover plate of the frame loader part and at its upper end by an upper cover plate of the wing bearing part.
  • a swing wing bearing is known from DE-C-1708217. Swing wing bearings are usually used to support the swing wing of a window, with the bearing axis running horizontally through the center of the wing. Rotating the wing about the first axis of rotation causes it to be inclined by a predetermined angle of rotation.
  • This position is used as the ventilation position of the window. If you then turn the wing about its second axis of rotation, the wing outer surface enters the interior, while the inner wing surface now points outwards. This position is intended as a cleaning position, since it allows the outer surface of the wing to be cleaned effortlessly from inside the room. The wing assumes a position parallel to its closed position, however, it is offset towards the interior of the room.
  • the sash and frame of modern swing windows are preferably made of aluminum or plastic profiles, but wooden frames are still in use.
  • the profile systems have both internal and external seals, so that drafts can practically not occur in the actual frame area. Because the upper wing half of a swing-wing bearing swivels into the interior of the room with a rotation around the first axis of rotation, while the lower wing half is moved outwards, a change in the sealing plane must take place in the bearing itself. This fact and also the well-known design of the swing wing bearings lead to creeping paths for drafts occurring in the swing wing bearing. If there is a leak at any point in the outer seal due to a processing or material defect, the air can enter the gaps between the alternating profile and the main profiles.
  • the swing-wing bearing remains as a display point for the passage of this air into the interior of the room. The user is therefore of the opinion that the oscillating-wing bearing as such would be leaky, even though the air entry took place at a different location.
  • the object of the invention is consequently seen in developing a swing-wing bearing of the type described at the outset in such a way that air passage is prevented with little effort and without increasing the tolerance requirements.
  • the swing-wing bearing is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim.
  • a rebate overlaps a rollover, and due to the leaking seal in the two pivoting wing bearings, there is also a leaping seal in the pivoting wing bearing seal formed by rollover and rebate, which enables the pivoting wing to move first about the first and subsequently or simultaneously about the second axis of rotation .
  • the width of the rebate and rollover depend on the tolerances in the manufacture of frame and sash as well as the amount by which the frame and sash bearing part can be pulled apart in the longitudinal direction of their axes of rotation if unfavorable tolerances and stresses. All of the above and the following explanations relate to the closed window and the built-in swing-wing bearing, for an observer standing inside the room.
  • the front end of the bearing is accordingly the end of the bearing which has visible surfaces and which faces the interior of the room.
  • the first axis of rotation lies below the second axis of rotation.
  • the frame bearing part have a fold extending from its upper end to the height of the first axis of rotation, and the rocker arm on its longitudinal edge assigned to the frame bearing part have a first projection which is laterally protruding and engages in the fold and has approximately the same length.
  • a fold of fold and rollover then takes place on the first axis of rotation, because with the Tilting movement of the wing about the first axis of rotation, pivot the upper part of the rocker arm with the wing bearing part into the interior, while the lower part is pivoted outwards. These swiveling movements must of course not be hindered by the fold extending into the neighboring part.
  • first sealing strip projecting laterally beyond the first rollover, which extends from the lower rocker arm end to approximately the height of the first axis of rotation and an edge at the lower end of the Reaches behind the frame bearing part.
  • This first sealing strip is advantageously molded on.
  • the length of the said edge corresponds at least to the length of the first sealing strip.
  • the piece of the latter located below the first axis of rotation and extending the fold on the frame bearing part is addressed.
  • the edge of the frame bearing part, which is engaged by the first sealing strip when the sash is closed, lies laterally next to the fold, that is to say further from the center of the rocker arm than the fold of the frame bearing part.
  • Another variant of the invention is characterized by a recess in the frame bearing part, the lower end of which is arched and shaped like a staircase, the radius of the arch corresponding to the radius of the movement path of the lower end of the rocker arm.
  • This recess is located essentially below the first axis of rotation, as seen from the interior of the room, starting behind the rear edge of the frame bearing part. It then extends to the lower cover plate of the frame bearing part. This creates an approximately wedge-shaped shape of the recess.
  • Their depth corresponds to the amount by which the first sealing strip protrudes laterally beyond the first rollover. With regard to the first landing, the depth corresponds to the width of the first rollover.
  • the end of the recess facing the lower cover plate also forms a stop for the rocker arm.
  • This stop limits the first rotary movement, i.e. the transfer of the wing from the closed position to the ventilation position.
  • another stop in the bearing can also be provided for this first rotary movement. In the case of a swing-wing bearing with simultaneous rotation about both axes, such a stop is not necessary.
  • the rocker arm on its longitudinal edge assigned to the wing bearing part has a laterally projecting second rollover from its lower end to the level of the second bearing axis, which folds into a fold extending from the lower end to the level of the second axis of rotation of the wing bearing part engages.
  • This is part of the seal between the rocker arm and the wing bearing part u. up to the second axis of rotation, where there is also a jump in the sealing plane, analogous to the jump between the frame bearing part and the rocker arm on the first axis of rotation.
  • This leap in the sealing plane takes place to the side. I.e. the parts of the sealing plane above and below the sealing step both lie in a common plane, but they are laterally offset from one another.
  • Another embodiment of the invention provides that at the upper end of the rocker arm on its longitudinal edge assigned to the wing bearing part there is a second sealing strip which projects laterally beyond the second flap and which engages behind an edge at the upper end of the wing bearing part which resets laterally with respect to the fold of the wing bearing part is. This creates the upper part of the seal between the rocker arm and wing bearing part, which extends from the upper end of the swing arm bearing to about the second axis of rotation.
  • the second sealing strip is located in a very advantageous manner on an element which is detachably held on the rocker arm or the second axis of rotation.
  • the element forms a brake part of the bearing, which is detachably connected to the upper rocker arm end and has or receives an element which acts in the manner of a sliding block or the like and which fits into a circumferential groove of one of the engages second axis of rotation forming pin of the wing bearing part.
  • the element acting as a sliding block can be the previously known screw-in element or a screw. Its shaft engages tangentially in the circumferential groove of the bearing journal.
  • a strip-like sealing element is attached to the upper and lower end face of the plate-like part of the rocker arm. It can be a circular cross-section that is pressed into a corresponding groove Act sealing element. To the left and right of this, a sealing element between the bearing and the further spar can also be used at the front end area of the frame or wing bearing part. In a comparable manner, the gap between the lower cover plate of the frame bearing part and the upper cover plate of the wing bearing part can also be sealed by switching a strip-like sealing element fastened to one of the cover plates between the facing end edges of the upper and lower cover plate.
  • the sealing element itself can have a strip-like shape. Instead, however, it can also be a molded-on strip of a plate which is attached to the inner surface of either the lower or the upper cover plate, for example by gluing.
  • the three most important elements of the swing wing bearing are the wing bearing part 1, the rocker arm 2 and the frame bearing part 3.
  • the rocker arm 2 is rotatably connected to both the wing bearing part and the frame bearing part, the first axis of rotation 4 serving for the pivotable articulation of the rocker arm on the frame bearing part 3, while the second axis of rotation 5 causes the rotatable articulation of the rocker arm on the wing bearing part 1.
  • Both rotary movements are limited and can only be carried out successively in a known manner. First, the wing is rotated about the first axis of rotation 1 into an oblique position, which serves as the ventilation position of the wing. The wing can then be rotated further until it has made a total of 180 ° rotation.
  • the outside pane is then easily accessible from the interior of the room, so that it can be cleaned without problems.
  • the sash assumes an inward parallel position, so that even in the rotating end position, the space can be ventilated via the gaps between the frame and sash frame.
  • the rotary movement of the wing is braked by means of a preferably adjustable brake, while a positive control, as said, ensures the successive sequence of the two rotary movements when opening and closing the wing.
  • Both the wing bearing part 1 and the frame bearing part 3 have an angular shape, whereby in the case of the wing bearing part 1 the one angle leg is formed by the upper cover plate 6 and in the frame bearing part 3 the one angle leg is formed by the lower cover plate 7.
  • the two cover plates are each shorter than the adjacent longitudinal edge of the other leg of the bearing part in question. When the bearing is closed, the two cover plates are directly one above the other, and together they form a bearing housing wall which is located inside the frame and points outwards. The gap between the two cover plates is sealed by means of a strip-like sealing element which is used on one of the two end edges, in particular on the upper end edge 9 of the lower cover plate 7.
  • This upper end edge 9 is shaped like a trough to form a retaining groove for the strip-like sealing element. Opposite is an inclined lower front edge 10 of the upper cover plate 6, which is pressed firmly against the strip-like sealing element 8 when the bearing is closed.
  • the rocker arm 2 consists essentially of the bearing leg 11 with the bearing bore 12 for the first axis of rotation 4 consisting of a pin and the plate-like part 13 arranged at right angles thereto. Its surface facing the interior forms a visible surface 14 of the swing-wing bearing. To the left of this is the visible surface 15 of the wing bearing part 1 in the installed state of the bearing and to the right of it the visible surface 16 of the frame bearing part 3.
  • the visible surface 15 is located at the front end region 17 of the wing bearing part and the visible surface 16 at the front end region 18 of the frame bearing part 3.
  • the plate-like part 13 of the rocker arm 2 and the front end regions 17 and 18 of the leaf or the frame bearing part are mutually folded and folded over sealed, as will be explained in more detail below. As a result, any outside air that may have entered the interior of the swing-wing bearing cannot escape into the interior of the room.
  • the frame bearing part 3 has a fold 19 extending from its upper end 20 to the level of the first axis of rotation 4. When the sash is closed, it is overlapped by a first flap 21 which is located on the Frame bearing part 3 associated longitudinal edge 22 of the rocker arm 2 is located. The length and shape of the flap 21 correspond to that of the fold 19. In addition, the flap 21, as shown in FIG. 3, is flush with the visible surface 14. At the lower end 23 of the rocker arm 2 there is a first on the longitudinal edge 22 associated with the frame bearing part 3 Rollover 21 laterally projecting first sealing strip 24. Its lower end also follows the front end region 18 of the frame bearing part 3, as is the case with the upper end of the first rollover 21 and the fold 19.
  • this first sealing strip 24 extends from the lower rocker arm end 23 to approximately the height of the first axis of rotation 4.
  • the frame bearing part 3 is provided with a recess 26, the shape and size and arrangement of the frame bearing part 3 with respect to the first axis of rotation 4 depends on the size and movement path of the first sealing strip 24.

Otherwise, the rocker arm has at this lower end 23 as well as at its upper end 29, u. on the plate-like part 13, a receiving groove 30 or 31 for a stiffened sealing element, not shown, which can correspond to that 8 at the upper end of the lower cover plate 7.
  • the rocker arm 2 has, on its longitudinal edge 32 assigned to the wing bearing part 1, a second rollover 34, which extends from its lower end 23 to the level of the second bearing axis 5 and projects laterally to the left (FIG. 2) and also ends flush with the visible surface 14.

Description

Die Erfindung Bezieht sich auf ein Schwingflügellager mit einem Rahmenlagerteil und einem Flügellagerteil sowie einem beide verbindenden Kipphebel, dessen eines Ende am Rahmenlagerteil und dessen anderes Ende am Flügellagerteil um eine erste und nachfolgend oder gleichzeitig um eine zweite Drehachse begrenzt drehbar gelagert sind, wobei das raumabgewandte Ende des Lagers an seinem in Einbaulage unteren Ende durch eine untere Deckplatte des Rahmenladerteils und an seinem oberen Ende durch eine Obere Deckplatte des Flügellagerteils verschlossen ist. Ein solches Schwingflügellager ist aus der DE-C-1708217 bekannt. Schwingflügellager dienen in der Regel zur Lagerung des Schwingflügels eines Fensters, wobei die Lagerachse horizontal durch die Mitte des Flügels verläuft. Ein Drehen des Flügels um die erste Drehachse bewirkt dessen Schrägstellung um einen vorgebenen Drehwinkel.The invention relates to a swinging wing bearing with a frame bearing part and a wing bearing part and a rocker arm connecting both, one end of which is rotatably supported on the frame bearing part and the other end on the wing bearing part about a first and subsequently or simultaneously about a second axis of rotation, the end facing away from the room of the bearing is closed at its lower end in the installed position by a lower cover plate of the frame loader part and at its upper end by an upper cover plate of the wing bearing part. Such a swing wing bearing is known from DE-C-1708217. Swing wing bearings are usually used to support the swing wing of a window, with the bearing axis running horizontally through the center of the wing. Rotating the wing about the first axis of rotation causes it to be inclined by a predetermined angle of rotation.

Diese Stellung wird als Lüftungsstellung des Fensters benutzt. Wenn man den Flügel nachfolgend um seine zweite Drehachse dreht, so gelangt die Flügelaußenfläche ins Rauminnere, während die Flügelinnenfläche nunmehr nach außen zeigt. Diese Stellung ist als Putzstellung gedacht, da sie ein müheloses Reinigen der Außenfläche des Flügels vom Rauminnern her gestattet. Der Flügel nimmt dabei eine zu seiner Schließstellung parallele Stellung ein, jedoch ist er dabei gegen das Rauminnere hin versetzt.This position is used as the ventilation position of the window. If you then turn the wing about its second axis of rotation, the wing outer surface enters the interior, while the inner wing surface now points outwards. This position is intended as a cleaning position, since it allows the outer surface of the wing to be cleaned effortlessly from inside the room. The wing assumes a position parallel to its closed position, however, it is offset towards the interior of the room.

Die Flügel- und Blendrahmen moderner Schwingflügelfenster werden in bevorzugter weise aus Aluminium- oder Kunststoffprofilen hergestellt jedoch sind auch noch Holzrahmen in Gebrauch. Bei den Profilsystemen sind sowohl Innen- wie auch Außendichtungen vorhanden, so daß im eigentlichen Rahmenbereich Zugluft praktisch nicht auftreten kann. Weil bei einem Schwingflügellager die obere Flügelhälfte bei einer Drehung um die erste Drehachse ins Rauminnere schwenkt, während die untere Flügelhälfte nach außen bewegt wird, muß im Lager selbst ein Wechsel in der Dichtebene stattfinden. Diese Tatsache und auch die bekannte Konstruktion der Schwingflügellager führen dazu, daß im Schwingflügellager Schleichwege für Zugluft entstehen. Wenn nun an irgendeiner Stelle der Außendichtung aufgrundeines Verarbeitungs-oder Materialfehlers eine undichte stelle vorhanden ist, so kann die Luft in die Spalträume zwischen dem wechselprofil und den Hauptprofilen eintreten. Da zusätzlich eine Innendichtung vorgesehen ist, bleibt als einzeige stelle für den Durchtritt deiser Luft ins Rauminnere das Schwingflügellager. Der Benutzer ist folglich der Meinung, daß das Schwingflügellager als solches undicht wäre, obwohl der Lufteintritt an einer anderen Stelle erfolgte.The sash and frame of modern swing windows are preferably made of aluminum or plastic profiles, but wooden frames are still in use. The profile systems have both internal and external seals, so that drafts can practically not occur in the actual frame area. Because the upper wing half of a swing-wing bearing swivels into the interior of the room with a rotation around the first axis of rotation, while the lower wing half is moved outwards, a change in the sealing plane must take place in the bearing itself. This fact and also the well-known design of the swing wing bearings lead to creeping paths for drafts occurring in the swing wing bearing. If there is a leak at any point in the outer seal due to a processing or material defect, the air can enter the gaps between the alternating profile and the main profiles. Since an inner seal is also provided, the swing-wing bearing remains as a display point for the passage of this air into the interior of the room. The user is therefore of the opinion that the oscillating-wing bearing as such would be leaky, even though the air entry took place at a different location.

Durch die DE-A-2 854 820 ist ein Schwingflügellager ähnlicher Art bekannt geworden, welches mit Hilfe von Dichtstreifen abgedichtet ist. Diese sind sowohl zwischen das Rahmenlagerteil und den Kipphebel bzw. zwischen letzteren und das Flügellagerteil geschaltet als auch zwischen das Rahmenprofil des Blendrahmens und das Rahmenlagerteil einerseits und das Profil des Flügels und das Flügellagerteil andererseits. Wie man aus dem Fensterbau weiß, ist eine derartige Konstruktion mit eingesetzten Dichtstreifen grundsätzlich toleranzempfindlich. Es kommt noch hinzu, daß sowohl die Dichtstreifen selbst als auch deren Montage zusätzliche Kosten verursachen. Im übrigen ist der Dichtstreifen ein Verschleißteil, welches von Zeit zu Zeit mit entsprechenden Kosten ausgetauscht werden muß.From DE-A-2 854 820 a swing-type bearing of a similar type has become known, which is sealed with the aid of sealing strips. These are connected between the frame bearing part and the rocker arm or between the latter and the wing bearing part as well as between the frame profile of the frame and the frame bearing part on the one hand and the profile of the wing and the wing bearing part on the other. As you know from window construction, such a construction with sealing strips used is generally sensitive to tolerances. There is also the fact that both the sealing strips themselves and their assembly cause additional costs. Otherwise, the sealing strip is a wearing part, which must be replaced from time to time with the corresponding costs.

Die Aufgabe der Erfindung wird infolgedessen darin gesehen, ein Schwingflügellager der eingangs beschriebenen Art so weiterzubilden, daß ein Luftdurchtritt mit geringstem Aufwand und ohne Erhöhung der Toleranzanforderungen verhindert wird.The object of the invention is consequently seen in developing a swing-wing bearing of the type described at the outset in such a way that air passage is prevented with little effort and without increasing the tolerance requirements.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß das Schwingflügellager gemäß dem Oberbegriff des Anspruchs 1 entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet ist. Bei diesem Lager übergreift jeweils ein Falz einen Überschlag, wobei aufgrund des Dichtungssprungs in den beiden Schwingflügellagern auch bei der durch Überschlag und Falz gebildeten Schwingflügellagerabdichtung ein Dichtungssprung vorhanden ist, der die Bewegung des Schwingflügels zunächst um die erste und nachfolgend oder gleichzeitig um die zweite Drehachse ermöglicht. Andererseits dichten aber Falz und Überschlag das Lager an seiner dem Rauminnern zugekehrten, die Sichtflächen aufweisenden Vorderseite ab, so daß dort keine Zugluft hindurchtreten kann. Die Breite von Falz und Überschlag richten sich nach den Toleranzen bei der Herstellung von Blend- und Flügelrahmen sowie dem Betrag, um welchen bei ungünstigen Toleranzen und Beanspruchungen das Rahmen- und das Flügellagerteil in Längsrichtung ihrer Drehachsen gegebenenfalls auseinandergezogen werden können. Alle vorstehenden und nachfolgenden Ausführungen beziehen sich jeweils auf das geschlossene Fenster und das eingebaute Schwingflügellager, und zwar für einen im Rauminnern stehenden Beobachter.To achieve this object, it is proposed according to the invention that the swing-wing bearing is designed in accordance with the preamble of claim 1 in accordance with the characterizing part of this claim. In this bearing, a rebate overlaps a rollover, and due to the leaking seal in the two pivoting wing bearings, there is also a leaping seal in the pivoting wing bearing seal formed by rollover and rebate, which enables the pivoting wing to move first about the first and subsequently or simultaneously about the second axis of rotation . On the other hand, fold and overlap seal the bearing on its front facing the interior, which has the visible surfaces, so that no drafts can pass through there. The width of the rebate and rollover depend on the tolerances in the manufacture of frame and sash as well as the amount by which the frame and sash bearing part can be pulled apart in the longitudinal direction of their axes of rotation if unfavorable tolerances and stresses. All of the above and the following explanations relate to the closed window and the built-in swing-wing bearing, for an observer standing inside the room.

Das vordere Lagerende ist demnach das die Sichtflächen aufweisende Lagerende, welches dem Rauminnern zugekehrt ist. In bekannter Weise liegt die erste Drehachse unterhalb der zweiten Drehachse. In Weiterbildung der Erfindung wird vorgeschlagen, daß das Rahmenlagerteil einen von seinem oberen Ende bis auf Höhe der ersten Drehachse reichenden Falz, und der Kipphebel an seinem dem Rahmenlagerteil zugeordneten Längsrand einen in den Falz eingreifenden, seitlich abstehenden ersten Überschlag etwa gleicher Länge aufweisen. An der ersten Drehachse findet dann ein Sprung von Falz und Überschlag statt, weil bei der Kippbewegung des Flügels um die erste Drehachse der obere Teil des Kipphebels mit dem Flügellagerteil ins Rauminnere schwenken, während der untere Teil nach außen hin verschwenkt wird. Diese Schwenkbewegungen dürfen selbstverständlich durch den ins Nachbarteil übergreifenden Falz nicht behindert werden.The front end of the bearing is accordingly the end of the bearing which has visible surfaces and which faces the interior of the room. In a known manner, the first axis of rotation lies below the second axis of rotation. In a further development of the invention, it is proposed that the frame bearing part have a fold extending from its upper end to the height of the first axis of rotation, and the rocker arm on its longitudinal edge assigned to the frame bearing part have a first projection which is laterally protruding and engages in the fold and has approximately the same length. A fold of fold and rollover then takes place on the first axis of rotation, because with the Tilting movement of the wing about the first axis of rotation, pivot the upper part of the rocker arm with the wing bearing part into the interior, while the lower part is pivoted outwards. These swiveling movements must of course not be hindered by the fold extending into the neighboring part.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß sich am unteren Ende des Kipphebels an dessen dem Rahmenlagerteil zugeordneten Längsrand eine den ersten Überschlag seitlich überragende erste Dichtleiste befindet, die vom unteren Kipphebelende bis etwa zur Höhe der ersten Drehachse reicht und eine Kante am unteren Ende des Rahmenlagerteils hintergreift. Diese erste Dichtleiste ist vorteilhafterweise angeformt. Die Länge der genannten Kante entspricht zumindest der Länge der ersten Dichtleiste. Der Begriff "unteres Ende des Rahmenlagerteils" bezieht sich dabei auf den vorderen Endbereich des Rahmenlagerteils der, in vertikaler Richtung gesehen, üblicherweise nicht so weit nach unten reicht als der hintere Endbereich des Rahmenlagerteils. Angesprochen ist in diesem Zusammenhang jedenfalls das unterhalb der ersten Drehachse gelegene, in Verlängerung des Falzes am Rahmenlagerteil befindliche Stück des letzteren. Außerdem liegt die Kante des Rahmenlagerteils, welche von der ersten Dichtleiste bei geschlossenem Flügel hintergriffen wird, seitlich neben dem Falz, also von der Mitte des Kipphebels weiter entfernt als der Falz des Rahmenlagerteils.In a further embodiment of the invention it is proposed that at the lower end of the rocker arm on its longitudinal edge assigned to the frame bearing part there is a first sealing strip projecting laterally beyond the first rollover, which extends from the lower rocker arm end to approximately the height of the first axis of rotation and an edge at the lower end of the Reaches behind the frame bearing part. This first sealing strip is advantageously molded on. The length of the said edge corresponds at least to the length of the first sealing strip. The term "lower end of the frame bearing part" refers to the front end region of the frame bearing part which, viewed in the vertical direction, usually does not extend as far down as the rear end region of the frame bearing part. In this context, the piece of the latter located below the first axis of rotation and extending the fold on the frame bearing part is addressed. In addition, the edge of the frame bearing part, which is engaged by the first sealing strip when the sash is closed, lies laterally next to the fold, that is to say further from the center of the rocker arm than the fold of the frame bearing part.

Eine andere Variante der Erfindung ist gekennzeichnet durch eine Ausnehmung im Rahmenlagerteil, deren unteres Ende bogenförmig begrenzt und treppenartig geformt ist, wobei der Radius des Bogen dem Radius der Bewegungsbahn des unteren Endes des Kipphebels entspricht. Diese Ausnehmung befindet sich im wesentlichen unterhalb der ersten Drehachse, und zwar vom Rauminnern her gesehen, beginnend hinter der hintergriffenen Kante des Rahmenlagerteils. Sie erstreckt sich dann bis hin zur unteren Deckplatte des Rahmenlagerteils. Es entsteht dadurch eine in etwa keilförmige Gestalt der Ausnehmung. Ihre Tiefe entspricht dem Betrag, um welchen die erste Dichtleiste seitlich über den ersten Überschlag Übersteht. Hinsichtlich des ersten Treppenabsatzes entspricht die Tiefe der Breite des ersten Überschlags.Another variant of the invention is characterized by a recess in the frame bearing part, the lower end of which is arched and shaped like a staircase, the radius of the arch corresponding to the radius of the movement path of the lower end of the rocker arm. This recess is located essentially below the first axis of rotation, as seen from the interior of the room, starting behind the rear edge of the frame bearing part. It then extends to the lower cover plate of the frame bearing part. This creates an approximately wedge-shaped shape of the recess. Their depth corresponds to the amount by which the first sealing strip protrudes laterally beyond the first rollover. With regard to the first landing, the depth corresponds to the width of the first rollover.

In weiterer Ausbildung der Erfindung wird vorgeschlagen, daß das der unteren Deckplatte zugekehrte Ende der Ausnehmung zugleich einen Anschlag für den Kipphebel bildet. Dieser Anschlag begrenzt die erste Drehbewegung, d.h. die Überführung des Flügels von der Schließstellung in die Lüftungsstellung. Zusätzlich oder alternativ kann man für diese erste Drehbewegung auch noch einen anderen Anschlag im Lager vorsehen. Bei einem Schwingflügellager mit gleichzeitiger Drehung um beide Achsen ist ein derartiger Anschlag nicht erforderlich.In a further embodiment of the invention it is proposed that the end of the recess facing the lower cover plate also forms a stop for the rocker arm. This stop limits the first rotary movement, i.e. the transfer of the wing from the closed position to the ventilation position. Additionally or alternatively, another stop in the bearing can also be provided for this first rotary movement. In the case of a swing-wing bearing with simultaneous rotation about both axes, such a stop is not necessary.

Eine zweckmäßige Weiterbildung der Erfindung besteht darin, daß der Kipphebel an seinem dem Flügellagerteil zugeordneten Längsrand einen von seinem unteren Ende bis auf Höhe der zweiten Lagerachse reichenden, seitlich abstehenden zweiten Überschlag aufweist, der in einen vom unteren Ende bis auf Höhe der zweiten Drehachse reichenden Falz des Flügellagerteils eingreift. Hierbei handelt es sich um einen Teil der Abdichtung zwischen dem Kipphebel und dem Flügellagerteil u. zwar bis hin zur zweiten Drehachse, wo dann ebenfalls ein Sprung in der Dichtebene stattfindet, analog dem Sprung zwischen Rahmenlagerteil und Kipphebel an der ersten Drehachse. Dieser Sprung in der Dichtebene erfolgt jeweils zur Seite hin. D.h. die Teile der Dichtebene oberhalb und unterhalb des Dichtungssprunges liegen beide in einer gemeinsamen Ebene, jedoch sind sie seitlich gegeneinander versetzt.An expedient development of the invention is that the rocker arm on its longitudinal edge assigned to the wing bearing part has a laterally projecting second rollover from its lower end to the level of the second bearing axis, which folds into a fold extending from the lower end to the level of the second axis of rotation of the wing bearing part engages. This is part of the seal between the rocker arm and the wing bearing part u. up to the second axis of rotation, where there is also a jump in the sealing plane, analogous to the jump between the frame bearing part and the rocker arm on the first axis of rotation. This leap in the sealing plane takes place to the side. I.e. the parts of the sealing plane above and below the sealing step both lie in a common plane, but they are laterally offset from one another.

Eine andere Ausgestaltung der Erfindung sieht vor, daß sich am oberen Ende des Kipphebels an dessen, dem Flügellagerteil zugeordneten Längsrand eine den zweiten Überschlag seitlich überragende zweite Dichtleiste befindet, die eine Kante am oberen Ende des Flügellagerteils hintergreift, welche gegenüber dem Falz des Flügellagerteils seitlich zurückgesetzt ist. Dadurch entsteht der obere Teil der Abdichtung zwischen Kipphebel und Flügellagerteil, der vom oberen Schwingflügellagerende bis etwa zur zweiten Drehachse reicht.Another embodiment of the invention provides that at the upper end of the rocker arm on its longitudinal edge assigned to the wing bearing part there is a second sealing strip which projects laterally beyond the second flap and which engages behind an edge at the upper end of the wing bearing part which resets laterally with respect to the fold of the wing bearing part is. This creates the upper part of the seal between the rocker arm and wing bearing part, which extends from the upper end of the swing arm bearing to about the second axis of rotation.

Die zweite Dichtleiste befindet sich in sehr vorteilhafter Weise an einem abnehmbar am Kipphebel oder der zweiten Drehachse gehaltenen Element. Hinsichtlich der ersten Alternative ergibt sich dadurch ein besonderer Vorteil, daß das Element ein Bremsteil des Lagers bildet, das mit dem oberen Kipphebelende abnehmbar verbunden ist und ein in der Art eines Gleitsteins oder dergleichen wirkendes Element aufweist oder aufnimmt, das in eine Umfangsnut eines, die zweite Drehachse bildenden Zapfens des Flügellagerteils eingreift. Bei dem als Gleitstein wirkenden Element kann es sich um das bisher bekannte Einschraubelement bzw. eine Schraube handeln. Ihr Schaft greift tangential in die Umfangsnut des Lagerzapfens ein. Aufgrund der verdeckten Anbringung dieser Schraube od. dgl. erhält man eine außen glatte Sichtfläche des Kipphebels und eine geschützte Anordnung der gesamten Axialsicherung für den Kipphebel im Lagerinnern. Das Einschraubelement ermöglicht das Aushängen des Flügels nach einer 180° Drehung.The second sealing strip is located in a very advantageous manner on an element which is detachably held on the rocker arm or the second axis of rotation. With regard to the first alternative, there is a particular advantage in that the element forms a brake part of the bearing, which is detachably connected to the upper rocker arm end and has or receives an element which acts in the manner of a sliding block or the like and which fits into a circumferential groove of one of the engages second axis of rotation forming pin of the wing bearing part. The element acting as a sliding block can be the previously known screw-in element or a screw. Its shaft engages tangentially in the circumferential groove of the bearing journal. Due to the hidden attachment of this screw or the like, an externally smooth visible surface of the rocker arm and a protected arrangement of the entire axial lock for the rocker arm inside the bearing is obtained. The screw-in element enables the sash to be unhooked after a 180 ° turn.

Um auch gegenüber den weiterführenden Rahmenprofilen ober- und unterhalb des Schwingflügellagers eine gute Abdichtung zu erzielen, ist es sehr zweckmäßig, wenn ein streifenartiges Dichtelement am oberen und unteren stirnseitigen Ende des plattenartigen Teils des Kipphebels angebracht ist. Dabei kann es sich um ein im Querschnitt kreisförmiges, in eine entsprechende Nut klemmend eingedrücktes Dichtelement handeln. Seitlich links und rechts davon kann man am vorderen Endbereich des Rahmen- bzw. Flügellagerteils jeweils auch noch ein Dichtelement zwischen Lager und weiterführenden Holm einsetzen. In vergleichbarer Art läßt sich auch noch der Spalt zwischen der unteren Deckplatte des Rahmenlagerteils und der oberen Deckplatte des Flügellagerteils abdichten, indem man in Weiterbildung der Erfindung zwischen die einander zugekehrten Stirnkanten der oberen und unteren Deckplatte ein an einer der Deckplatten befestigtes, streifenartiges Dichtelement schaltet. Dabei kann das Dichtelement selbst eine streifenartige Form haben. Statt dessen kann es sich aber auch um ein angeformte Leiste einer platte handeln, die an der Innenfläche entweder der unteren oder der oberen Deckplatte befestigt, beispielsweise angeklebt wird.In order to achieve a good seal against the further frame profiles above and below the swing wing bearing, it is very expedient if a strip-like sealing element is attached to the upper and lower end face of the plate-like part of the rocker arm. It can be a circular cross-section that is pressed into a corresponding groove Act sealing element. To the left and right of this, a sealing element between the bearing and the further spar can also be used at the front end area of the frame or wing bearing part. In a comparable manner, the gap between the lower cover plate of the frame bearing part and the upper cover plate of the wing bearing part can also be sealed by switching a strip-like sealing element fastened to one of the cover plates between the facing end edges of the upper and lower cover plate. The sealing element itself can have a strip-like shape. Instead, however, it can also be a molded-on strip of a plate which is attached to the inner surface of either the lower or the upper cover plate, for example by gluing.

Die Erfindung wird nachfolgend anhand eines Ausführungsbeispiels näher erläutert. Dabei handelt es sich um Schrägbilddarstellungen, wobei bekannte und im Zusammenhang mit der erfindungsgemäßen Ausbildung nicht interessierende Details der Übersichtlichkeit halber weggelassen sind, so beispielsweise die Bremse und die Steuerung, welche sicherstellt, daß die Drehbewegung um die zweite Achse erst dann stattfindet, wenn die Drehbewegung um die erste Achse beendet ist. Es zeigen:

  • Fig. 1 das Flügellagerteil,
  • Fig. 2 den Kipphebel, wobei die Seite sichtbar ist, die dem Flügellagerteil zugekehrt ist,
  • Fig. 3 nochmals den Kipphebel, wobei die dem Rahmenteil zugekehrte Fläche sichtbar ist und
  • Fig. 4 das Rahmenlagerteil.
The invention is explained in more detail below using an exemplary embodiment. These are skewed representations, whereby known details which are of no interest in connection with the design according to the invention are omitted for the sake of clarity, for example the brake and the control, which ensures that the rotary movement about the second axis only takes place when the rotary movement about the first axis is finished. Show it:
  • 1 the wing bearing part,
  • 2 shows the rocker arm, the side that is facing the wing bearing part is visible,
  • Fig. 3 again the rocker arm, the surface facing the frame part is visible and
  • Fig. 4, the frame bearing part.

Die drei wesentlichsten Elemente des Schwingflügellagers sind das Flügellagerteil 1, der Kipphebel 2 und das Rahmenlagerteil 3. Der Kipphebel 2 ist drehbar sowohl mit dem Flügellagerteil als auch dem Rahmenlagerteil verbunden, wobei die erste Drehachse 4 der drehbaren Anlenkung des Kipphebels am Rahmenlagerteil 3 dient, während die zweite Drehachse 5 die drehbare Anlenkung des Kipphebels am Flügellagerteit 1 bewirkt. Beide Drehbewegungen sind begrenzt und können in bekannter Weise nur aufeinanderfolgend vorgenommen werden. Zunächst erfolgt ein Drehen des Flügels um die erste Drehachse 1 in eine schräge Stellung, die als Lüftungsstellung des Flügels dient. Nachfolgend kann dann der Flügel weitergedreht werden, bis er insgesamt eine 180° Drehung durchgeführt hat. Dadurch wird dann die außen liegende Scheibe vom Rauminnern her leicht zugänglich, so daß sie problemlos gereinigt werden kann. Der Flügel nimmt gegenüber der Schließstellung eine nach innen versetzte parallellage ein, so daß man auch in der Drehendstellung den Raum über die entstandenen Spalte zwischen Blendrahmen und Flügelrahmen lüften kann. In bekannter Weise wird die Drehbewegung des Flügels mittels einer vorzugsweise einstellbaren Bremse gebremst, während eine Zwangssteuerung, wie gesagt, den aufeinanderfolgenden Ablauf der beiden Drehbewegungen beim Offnen und Schließen des Flügels gewährleistet.The three most important elements of the swing wing bearing are the wing bearing part 1, the rocker arm 2 and the frame bearing part 3. The rocker arm 2 is rotatably connected to both the wing bearing part and the frame bearing part, the first axis of rotation 4 serving for the pivotable articulation of the rocker arm on the frame bearing part 3, while the second axis of rotation 5 causes the rotatable articulation of the rocker arm on the wing bearing part 1. Both rotary movements are limited and can only be carried out successively in a known manner. First, the wing is rotated about the first axis of rotation 1 into an oblique position, which serves as the ventilation position of the wing. The wing can then be rotated further until it has made a total of 180 ° rotation. As a result, the outside pane is then easily accessible from the interior of the room, so that it can be cleaned without problems. Compared to the closed position, the sash assumes an inward parallel position, so that even in the rotating end position, the space can be ventilated via the gaps between the frame and sash frame. In a known manner, the rotary movement of the wing is braked by means of a preferably adjustable brake, while a positive control, as said, ensures the successive sequence of the two rotary movements when opening and closing the wing.

Sowohl das Flügellagerteil 1 als auch das Rahmenlagerteil 3 haben eine winkelförmige Gestalt,.wobei im Fall des Flügellagerteils 1 der eine Winkelschenkel durch die obere Deckplatte 6 und beim Rahmenlagerteil 3 der eine Winkelschenkel durch die untere Deckplatte 7 gebildet ist. Die beiden Deckplatten sind, wie die Figuren 1 und 4 zeigen, jeweils kürzer als die benachbarte Längskante des anderen Schenkel des betreffenden Lagerteils. Bei geschlossenem Lager stehen die beiden Deckplatten unmittelbar übereinander, und sie bilden zusammen eine innen im Rahmen liegende, nach außen weisende Lagergehäusewand. Der Spalt zwischen den beiden Deckplatten wird mittels eines streifenartigen Dichtelements abgedichtet, das an einer der beiden Stirnkanten eingesetzt wird, insbesondere an der oberen Stirnkante 9 der unteren Deckplatte 7. Diese obere Stirnkante 9 ist zur Bildung einer Haltenut für das streifenartige Dichtelement muldenartig geformt. Gegenüberliegend befindet sich eine schräg verlaufende untere Stirnkante 10 der oberen Deckplatte 6, die bei geschlossenem Lager fest an dem streifenartigen Dichtelement 8 angepreßt ist.Both the wing bearing part 1 and the frame bearing part 3 have an angular shape, whereby in the case of the wing bearing part 1 the one angle leg is formed by the upper cover plate 6 and in the frame bearing part 3 the one angle leg is formed by the lower cover plate 7. As shown in FIGS. 1 and 4, the two cover plates are each shorter than the adjacent longitudinal edge of the other leg of the bearing part in question. When the bearing is closed, the two cover plates are directly one above the other, and together they form a bearing housing wall which is located inside the frame and points outwards. The gap between the two cover plates is sealed by means of a strip-like sealing element which is used on one of the two end edges, in particular on the upper end edge 9 of the lower cover plate 7. This upper end edge 9 is shaped like a trough to form a retaining groove for the strip-like sealing element. Opposite is an inclined lower front edge 10 of the upper cover plate 6, which is pressed firmly against the strip-like sealing element 8 when the bearing is closed.

Der Kipphebel 2 besteht im wesentlichen aus dem Lagerschenkel 11 mit der Lagerbohrung 12 für die aus einem Zapfen bestehende erste Drehachse 4 und dem dazu rechtwinklig angeordneten plattenartigen Teil 13. Dessen, dem Rauminnern zugekehrte Fläche bildet eine Sichtfläche 14 des Schwingflügellagers. Links daneben befindet sich in eingebautem Zustand des Lagers die Sichtfläche 15 des Flügellagerteils 1 und rechts davon die Sichtfläche 16 des Rahmenlagerteils 3.The rocker arm 2 consists essentially of the bearing leg 11 with the bearing bore 12 for the first axis of rotation 4 consisting of a pin and the plate-like part 13 arranged at right angles thereto. Its surface facing the interior forms a visible surface 14 of the swing-wing bearing. To the left of this is the visible surface 15 of the wing bearing part 1 in the installed state of the bearing and to the right of it the visible surface 16 of the frame bearing part 3.

Dabei befindet sich die Sichtfläche 15 am vorderen Endbereich 17 des Flügellagerteils und die Sichtfläche 16 am vorderen Endbereich 18 des Rahmenlagerteils 3. Der plattenartige Teil 13 des Kipphebels 2 und die vorderen Endbereiche 17 und 18 des Flügel bzw. des Rahmenlagerteils sind mittels Falz und Überschlag gegeneinander abgedichtet, wie nachstehend noch näher erläutert wird. Dadurch kann gegebenenfalls ins Lagerinnere eingetretene Außenluft am Schwingflügellager nicht ins Rauminnere austreten. Ein Wechsel in den Dichtflächen der Fälze und Überschläge zwischen dem Rahmenlagerteil und dem Kipphebel, etwa auf Höhe der ersten Drehachse 4, und zwischen dem Kipphebel und dem Flügellagerteil, etwa auf Höhe der zweiten Drehachse 5, gewährleisten trotz des seitlichen Übergreifens der drei hauptsächlichen Teile des Schwingflügellagers ein ungehindertes Drehen um die erste und nachfolgend oder gleichzeitig um die zweite Drehachse.The visible surface 15 is located at the front end region 17 of the wing bearing part and the visible surface 16 at the front end region 18 of the frame bearing part 3. The plate-like part 13 of the rocker arm 2 and the front end regions 17 and 18 of the leaf or the frame bearing part are mutually folded and folded over sealed, as will be explained in more detail below. As a result, any outside air that may have entered the interior of the swing-wing bearing cannot escape into the interior of the room. A change in the sealing surfaces of the folds and rollovers between the frame bearing part and the rocker arm, approximately at the level of the first axis of rotation 4, and between the rocker arm and the wing bearing part, approximately at the level of the second axis of rotation 5, ensure despite the lateral overlap of the three main parts of the Swing wing bearing an unhindered rotation around the first and subsequent or simultaneously around the second axis of rotation.

Das Rahmenlagerteil 3 besitzt einen von seinem oberen Ende 20 bis auf Höhe der ersten Drehachse 4 reichenden Falz 19. Er wird bei geschlossenem Flügel von einem ersten Überschlag 21 übergriffen, der sich an dem dem Rahmenlagerteil 3 zugeordneten Längsrand 22 des Kipphebel 2 befindet. Die Länge und Form des Uberschlags 21 entsprechen denjenigen des Falzes 19. Außerdem ist der Überschlag 21, wie Fig 3 zeigt, bündig mit der Sichtfläche 14. Am unteren Ende 23 des Kipphebels 2 befindet sich an dessen dem Rahmenlagerteil 3 zugeordneten Längsrand 22 eine den ersten Überschlag 21 seitlich überragende erste Dichtleiste 24. Ihr unteres Ende folgt ebenso dem vorderen Endbereich 18 des Rahmenlagerteils 3, wie dies beim oberen Ende des ersten Überschlags 21 und dem Falz 19 der Fall ist.The frame bearing part 3 has a fold 19 extending from its upper end 20 to the level of the first axis of rotation 4. When the sash is closed, it is overlapped by a first flap 21 which is located on the Frame bearing part 3 associated longitudinal edge 22 of the rocker arm 2 is located. The length and shape of the flap 21 correspond to that of the fold 19. In addition, the flap 21, as shown in FIG. 3, is flush with the visible surface 14. At the lower end 23 of the rocker arm 2 there is a first on the longitudinal edge 22 associated with the frame bearing part 3 Rollover 21 laterally projecting first sealing strip 24. Its lower end also follows the front end region 18 of the frame bearing part 3, as is the case with the upper end of the first rollover 21 and the fold 19.

Demnach reicht also diese erste Dichtleiste 24 vom unteren Kipphebelende 23 bis etwa zur Höhe der ersten Drehachse 4. Sie hintergreift bei geschlossenem Flügel eine Kante 25 am unteren Ende des Endbereichs 18 des Rahmenlagerteils 3. Um dies zu ermöglichen, ist es erforderlich, daß das Rahmenlagerteil 3 mit einer Ausnehmung 26 versehen ist, deren Form und Größe sowie Anordnung am Rahmenlagerteil 3 bezüglich der ersten Drehachse 4 von der Größe und Bewegungsbahn der ersten Dichtleiste 24 abhängt. Weil letztere gegenüber der Ebene des plattenartigen Teils 13 des Kipphebels 2 zurückversetzt ist, ist die Ausnehmung 26 an ihrem unteren Ende 27 treppenartig ausgeformt. Außerdem ist sie dort entsprechend dem Bewegungsradius des unteren Endes der ersten Dichtleiste 24 bogenförmig geformt. Das der unteren Deckplatte 7 am Rahmenlagerteil 3 zugekehrte Ende 28 der Ausnehmung 26 bildet zugleich einen Anschlag für den Kipphebel 2. Er begrenzt dessen Aufklapp-Drehbewegung gegenüber dem Rahmenlagerteil 3 und er arbeitet mit dem unteren Ende 23 des Kipphebels 2 zusammen. Im übrigen besitzt der Kipphebel an diesem unteren Ende 23 ebenso wie an seinem oberen Ende 29, u. zwar am plattenartigen Teil 13, eine Aufnahmenut 30 bzw. 31 für ein steifenartiges, nicht gezeigtes Dichtelement, welches demjenigen 8 am oberen Ende der unteren Deckplatte 7 entsprechen kann.Accordingly, this first sealing strip 24 extends from the lower rocker arm end 23 to approximately the height of the first axis of rotation 4. When the sash is closed, it engages behind an edge 25 at the lower end of the end region 18 of the frame bearing part 3. To make this possible, it is necessary that the frame bearing part 3 is provided with a recess 26, the shape and size and arrangement of the frame bearing part 3 with respect to the first axis of rotation 4 depends on the size and movement path of the first sealing strip 24. Because the latter is set back in relation to the plane of the plate-like part 13 of the rocker arm 2, the recess 26 is shaped like a step at its lower end 27. In addition, it is shaped in an arc shape there according to the radius of movement of the lower end of the first sealing strip 24. The end 28 of the recess 26 facing the lower cover plate 7 on the frame bearing part 3 at the same time forms a stop for the rocker arm 2. It limits its swing-open movement relative to the frame bearing part 3 and it cooperates with the lower end 23 of the rocker arm 2. Otherwise, the rocker arm has at this lower end 23 as well as at its upper end 29, u. on the plate-like part 13, a receiving groove 30 or 31 for a stiffened sealing element, not shown, which can correspond to that 8 at the upper end of the lower cover plate 7.

Der Kipphebel 2 besitzt an seinem, dem Flügellagerteil 1 zugeordneten Längsrand 32 einen von seinem unteren Ende 23 bis auf Höhe der zweiten Lagerachse 5 reichenden seitlich nach links (Fig. 2) abstehenden zweiten Überschlag 34, der ebenfalls bündig mit der Sichtfläche 14 abschließt. Er greift bei geschlossenem Lager in einen vom unteren Ende 35 bis auf Höhe der zweiten Drehachse 5 reichenden Falz 36 des Flügellagerteils 1 ein.The rocker arm 2 has, on its longitudinal edge 32 assigned to the wing bearing part 1, a second rollover 34, which extends from its lower end 23 to the level of the second bearing axis 5 and projects laterally to the left (FIG. 2) and also ends flush with the visible surface 14. When the bearing is closed, it engages in a fold 36 of the wing bearing part 1 which extends from the lower end 35 to the level of the second axis of rotation 5.

Des weiteren befindet sich am oberen Ende 29 des Kipphebels 2, und zwar an dessen dem Flügellagerteil 1 zugeordneten Längsrand 32, eine den zweiten Überschlag 34 seitlich überragende zweite Dichtleiste 37. Sie ist an einem abnehmbar am Kipphebel 2 gehaltenen Element 38 angeformt. Es wird in nicht näher gezeigter Weise mit dem Kipphebel 2 verschraubt und besitzt zu diesem Zwecke eine Durchsteckbohrung 39 für eine in ein Gewinde des Kipphebels 2 einzudrehende Schraube. An seiner Unterseite befindet sich eine Mulde, die den als zweite Drehachse 5 dienenden Zapfen des Flügellagerteils von oben übergreift, wobei dieser Zapfen andererseits in der Lagermulde 40 des Kipphebels 2 ruht. Am Zapfen 5 ist eine Umfangsnut 41 vorgesehen, in welche tangential der Schaft der erwähnten Befestigungsschraube für das Element 38 eingreift und dadurch die axiale Sicherung des Kipphebels 2 auf dem Zapfen 5 bewirkt, ohne die Relativdrehung von Kipphebel und Flügellagerteil zu behindern.Furthermore, at the upper end 29 of the rocker arm 2, namely on its longitudinal edge 32 assigned to the wing bearing part 1, there is a second sealing strip 37 which laterally projects beyond the second flap 34. It is formed on an element 38 which is detachably held on the rocker arm 2. It is screwed to the rocker arm 2 in a manner not shown in detail and for this purpose has a through hole 39 for a screw to be screwed into a thread of the rocker arm 2. On its underside there is a trough which overlaps the pin of the wing bearing part serving as the second axis of rotation 5, said pin resting on the other hand in the bearing trough 40 of the rocker arm 2. On the pin 5, a circumferential groove 41 is provided, in which tangentially the shaft of the mentioned fastening screw for the element 38 engages and thereby brings about the axial securing of the rocker arm 2 on the pin 5 without hindering the relative rotation of the rocker arm and wing bearing part.

Die zweite Dichtleiste 37 hintergreift eine Kante 42 am oberen Ende des Flügellagerteils 1. Diese ist gegenüber dem Falz 36 seitlich nach links (Fig. 1) zurückgesetzt. In sehr vorteilhafter Weise liegen der Falz 19 und der Überschlag 24 einerseits sowie der Falz 36 und der Überschlag 37 andererseits bei geschlossenem Lager jeweils stirnseitig aneinander an, so daß auch an diesen Stellen eine Abdichtung erzielt wird.The second sealing strip 37 engages behind an edge 42 at the upper end of the wing bearing part 1. This is set laterally to the left relative to the fold 36 (FIG. 1). In a very advantageous manner, the fold 19 and the flap 24 on the one hand and the fold 36 and the flap 37 on the other hand each abut one another on the end face when the bearing is closed, so that a seal is also achieved at these points.
