Description

Die Erfindung bezieht sich auf ein als unteres bandseitiges Lager eines Dreh-Kipp-Beschlags ausgebildetes Lager für einen Flügel eines Fensters, einer Tür od. dgl., mit einem Rahmen-Lagerteil und einem Flügel-Lagerteil, wobei das Rahmen-Lagerteil einen Lagerzapfen und das Flügel-Lagerteil eine Lagerhülse mit einer Lagerbohrung aufweist, die an ihrem oberen Ende mit einem axial einstellbaren Lagerstück versehen ist. Ein solches Lager ist durch die EP-A 0 010 144 bekannt geworden. Dieses Lager ermöglicht aufgrund seines in vertikaler Richtung verstellbaren Lagerstücks eine Vertikalausrichtung des Flügels. Ansonsten ist es ein normalgängiges Lager, welches ohne besonderen Kraftaufwand geöffnet und geschlossen werden kann. Solche Lager haben den Nachteil, daß sie sehr genau eingebaut werden müssen. Wenn der Flügel nicht exakt im Lot steht, so führt dies zu einer unerwünschten Flügelbewegung gegenüber seinem festen Rahmen. Der Flügel bleibt deshalb in einer geringen Drehöffnungsstellung, die zu Lüftungszwecken an sich ausreichen würde, nicht stehen.The invention relates to a formed as a lower hinge-side bearing of a turn-tilt fitting bearing for a wing of a window, a door or the like. With a frame bearing part and a wing bearing part, the frame bearing part, a bearing pin and the wing bearing part has a bearing sleeve with a bearing bore, which is provided at its upper end with an axially adjustable bearing piece. Such a bearing is known from EP-A 0 010 144. This bearing enables a vertical alignment of the wing due to its vertically adjustable bearing piece. Otherwise it is a normal-running bearing, which can be opened and closed without any special effort. Such bearings have the disadvantage that they have to be installed very precisely. If the wing is not exactly perpendicular, this leads to an undesirable wing movement in relation to its fixed frame. The sash therefore does not remain in a small opening position, which would be sufficient for ventilation purposes.

Durch die US-A 4 490 884 ist ein Lager für einen drehbar gelagerten Flügel bekannt geworden, dessen Reibungswiderstand beim Öffnen veränderbar ist. Man kann die Veränderung bis hin zur Schwergängigkeit erhöhen. Dieser Flügel kann also selbst bei nicht ganz korrekter Montage in der jeweils gewünschten Öffnungslage stehen bleiben, wenn man die Schwergängigkeit dementsprechend einstellt. Hierbei wird es allerdings als nachteilig angesehen, daß der Flügel in vertikaler Richtung gegenüber dem festen Rahmen nicht justiert werden kann. Infolgedessen muß man ihn zumindest insoweit sehr genau montieren, was einen entsprechenden Aufwand mit sich bringt.From US-A 4 490 884 a bearing for a rotatably mounted wing is known, the frictional resistance of which can be changed when opened. You can increase the change up to stiffness. This wing can therefore remain in the desired opening position even if the assembly is not completely correct, if you adjust the stiffness accordingly. Here, however, it is considered disadvantageous that the sash cannot be adjusted in the vertical direction relative to the fixed frame. As a result, it has to be mounted very precisely, at least in so far, which entails a corresponding outlay.

Durch die US-A 1 745 545 ist ein Beschlag bekannt geworden, mit dem man eine drehbar gelagerte Tür mehr oder weniger schwergängig justieren kann. Hierzu wird jedoch ein aufwendiger, komplizierter und damit auch störanfälliger Mechanismus vorgeschlagen, der für eine Verwendung bei einem modernen Fensterbeschlag nicht in Frage kommt. Sowohl bei diesem Beschlag als auch dem zuvor besprochenen Lager nach der US-A 4 490 884 erfolgt die Veränderung der Reibung jeweils mit Hilfe einer Klemmhülse. Auch beim Beschlag der US-A 1 745 545 ist eine Vertikaleinstellung der Tür nicht möglich.A fitting has become known from US-A 1 745 545, with which one can adjust a rotatably mounted door to a greater or lesser degree. For this purpose, however, a complex, complicated and thus also failure-prone mechanism is proposed, which is out of the question for use in a modern window fitting. Both in this fitting and in the previously discussed bearing according to US Pat. No. 4,490,884, the friction is changed with the aid of a clamping sleeve. A vertical adjustment of the door is also not possible when fitting US-A 1 745 545.

Die Aufgabe der Erfindung wird nun darin gesehen, ein Lager gemäß dem Oberbegriff des Anspruchs 1 so weiterzubilden, daß unter Beibehaltung der vertikalen Einstellmöglichkeit des Flügels das unerwünschte Verstellen aus einer vom Benutzer vorgegebenen Drehlage zumindest erschwert wird, ohne daß dies zu einer nachteiligen Beeinflussung der Bedienung des Flügels führt.The object of the invention is seen in further developing a bearing according to the preamble of claim 1 so that while maintaining the vertical adjustment of the wing the undesired adjustment from a rotational position specified by the user is at least made more difficult without this having an adverse effect on the operation of the wing leads.

Zur Lösung dieser Aufgabe wird erfindungsgemäß vorgeschlagen, daß das Lager gemäß dem Oberbegriff des Anspruchs 1 entsprechend dem kennzeichnenden Teil dieses Anspruchs ausgebildet ist. Durch die nunmehr mögliche Veränderung des Lagerbohrungsquerschnittes im Bereich des unteren Teils der Lagerhülse kann man das Spiel zwischen Lagerzapfen und Lagerbohrung so festlegen, daß der Flügel einerseits nicht schwergängig wird, andererseits aber bei nicht ganz perfekten Einbau des Fensters oder der Tür eine Lagerreibung vorhanden ist, welche das Verstellen unter dem Eigengewicht oder unter einem Luftzug zumindest erschwert, vorzugsweise aber vermeidet. Trotzdem bleibt die Möglichkeit der Vertikalausrichtung des Flügels erhalten.To solve this problem, the invention proposes that the bearing is designed according to the preamble of claim 1 in accordance with the characterizing part of this claim. Due to the now possible change in the bearing bore cross-section in the area of the lower part of the bearing sleeve, the play between the bearing journal and the bearing bore can be determined in such a way that the sash does not become stiff on the one hand, but bearing friction is present if the window or door is not perfectly installed, which at least complicates the adjustment under the dead weight or under a draft, but preferably avoids it. Nevertheless, the possibility of vertical alignment of the wing remains.

Es ist nicht unbedingt notwendig, daß der Lagerdurchmesser zentrisch verengt oder erweitert wird, vielmehr erreicht man eine Klemmung auch durch eine leichte federelastische Verformung der Lagerbohrung, wobei der ursprünglich runde Querschnitt nicht mehr vollkommen erhalten bleibt. Wegen der geringen, hier in Betracht kommenden Veränderung des Lagerspiels hat dies aber auf die Lagerung selbst keinen nachteiligen Einfluß.It is not absolutely necessary for the bearing diameter to be narrowed or widened in the center; rather, clamping is also achieved by slightly resiliently deforming the bearing bore, the originally round cross section no longer being completely preserved. Because of the small change in the bearing play that is considered here, this has no adverse effect on the bearing itself.

Andererseits ermöglicht diese Veränderung des wirksamen Lagerspiels eine Herstellung der einzelnen Teile mit größerer Toleranz als bisher üblich, so daß der evtl. auftretende bauliche Mehraufwand hierdurch wieder ausgeglichen wird.On the other hand, this change in the effective bearing play enables the individual parts to be manufactured with a greater tolerance than was previously the case, so that any additional structural effort that may occur is compensated for again.

Eine Weiterbildung der Erfindung sieht vor, daß der untere Teil der Lagerhülse als Klemmhülse ausgebildet ist. Er kann mittels wenigstens einer Klemmschraube verengt werden. Klemmschrauben eignen sich in besonderer Weise zur sehr feinfühligen Veränderung des Lagerspiels bzw. der Bremswirkung. Ein besonderes Sicherungselement ist in der Regel nicht erforderlich, vielmehr ist die Klemmschraube meist selbsthemmend.A further development of the invention provides that the lower part of the bearing sleeve is designed as a clamping sleeve. It can be narrowed using at least one clamping screw. Clamping screws are particularly suitable for very sensitive changes in the bearing play or the braking effect. A special securing element is usually not necessary, rather the clamping screw is usually self-locking.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, daß sich im geschlitzten Teil der Lagerhülse ein geschlitzter hülsenförmiger Bremsring, vorzugsweise aus Kunststoff, befindet. In der Regel reicht ein einziger Schlitz der Lagerhülse und des Bremsrings aus. Durch die Schlitzbreite sowie die federelastischen Eigenschaften von Lagerhülse und Bremsring wird das theoretisch maximal mögliche Maß der Lagerbohrungsverengung festgelegt. Bei eingestecktem Lagerzapfen wird dieses Maximalmaß jedoch kaum ausgenutzt. Somit ergeben sich auch praktisch keine nennenswerten Abweichungen von der zylindrischen Form. Wenn die Lagerhülse auf ihrer gesamten Länge geschlitzt ist, so erstreckt sich zweckmäßigerweise auch der hülsenförmige Bremsring über etwa die gesamte Lagerhülsenlänge. Bei Kunststoffausführung ist ein Material zu wählen, das einerseits den auftretenden Belastungen standhält und andererseits eine Eignung als Lagermaterial besitzt.In a further embodiment of the invention it is proposed that a slotted sleeve-shaped brake ring, preferably made of plastic, is located in the slotted part of the bearing sleeve. As a rule, a single slot in the bearing sleeve and the brake ring is sufficient. The slot width and the spring-elastic properties of the bearing sleeve and brake ring determine the theoretically maximum possible dimension of the bearing bore narrowing. However, this maximum dimension is hardly used when the bearing journal is inserted. This means that there are practically no significant deviations from the cylindrical shape. If the bearing sleeve is slotted over its entire length, the sleeve-shaped brake ring expediently also extends over approximately the entire length of the bearing sleeve. In the case of plastic, a material must be selected that on the one hand withstands the loads that occur and on the other hand is suitable as a bearing material.

Eine weitere Variante der Erfindung kennzeichnet sich dadurch, daß der Bremsring drehfest in der Lagerhülse bzw. deren als Klemmhülse ausgebildetem Teilstück gehalten ist. Man verhindert dadurch ein Drehen des Bremsrings in der Lagerhülse, so daß für das Drehen bzw. Halten des Flügels nur die Reibung zwischen dem Klemmhülseninnern und dem Material des Lagerzapfens maßgeblich ist.A further variant of the invention is characterized in that the brake ring is held in a rotationally fixed manner in the bearing sleeve or in its section designed as a clamping sleeve. This prevents the brake ring from rotating in the bearing sleeve, so that only the friction between the inside of the clamping sleeve and the material of the bearing journal is decisive for turning or holding the wing.

Weitere Ausgestaltungen und Vorteile des erfindungsgemäßen Lagers ergeben sich aus der nachfolgenden Zeichnungsbeschreibung.Further configurations and advantages of the bearing according to the invention result from the following description of the drawings.

Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung. Hierbei stellen dar:

  • Fig. 1 Eine Seitenansicht des in der erfindungsgemäßen Weise ausgebildeten Lagerteils des Lagers der in Frage stehenden Art,
  • Fig. 2 in vergrößertem Maßstab einen Schnitt gemäß der Linie 11-11 der Fig. 1.
The drawing shows an embodiment of the invention. Here represent:
  • 1 is a side view of the bearing part of the bearing of the type in question, designed in the manner according to the invention,
  • 2 is an enlarged section along the line 11-11 of FIG. 1st

Beim Ausführungsbeispiel handelt es sich um ein Dreh-Kipp-Lager mit einem Flügel-Lagerteil 1 und einem nicht dargestellten in herkömmlicher Weise ausgebildeten Lagerteil eines festen Rahmens. Die Lagerhülse 2 befindet sich dabei am Flügel-Lagerteil 1, während sich der in diesem Falle schwenkbar gelagerte Lagerzapfen, welcher von unten her in Richtung des Pfeils 3 in die Lagerhülse 2 eingreift, am Lagerteil des festen Rahmens befindet. Demnach ist der Flügel im Sinne des Dopelpfeils 4 um die geometrische Achse 5 des Lagerzapfens drehbar und in Richtung des Pfeils 6 in eine Kippstellung überführbar. Die geometrische Zapfenachse 5 ist zugleich auch die geometrische Achse der Lagerhülse 2. Die geometrische Kippachse 7 ist in Fig. 1 symbolisch eingetragen.In the embodiment, it is a turn-tilt bearing with a wing bearing part 1 and a bearing part of a fixed frame not shown in the conventional manner. The bearing sleeve 2 is located on the wing bearing part 1, while in this case the pivot pin, which engages from below in the direction of arrow 3 in the bearing sleeve 2, is located on the bearing part of the fixed frame. Accordingly, the wing can be rotated in the sense of double arrow 4 about the geometric axis 5 of the bearing journal and can be converted into a tilting position in the direction of arrow 6. The geometric pin axis 5 is also the geometric axis of the bearing sleeve 2. The geometric tilt axis 7 is symbolically entered in FIG. 1.

Das Lager des Ausführungsbeispiels dient insbesondere zum Lagern eines vergleichweise schweren Flügels eines Fenster oder einer Tür an einem Blendrahmen. Infolgedessen ist es als verstärkte Ausführung mit Tragwinkeln 8 und 9 ausgebildet In Verlängerung des kurzen Winkelschenkels des Tragwinkels 8 erstreckt sich noch ein damit einstückig gefertigter unterer Tragarm 10. Dieser und die beiden vertikalen Schenkel der Tragwinkel 8 und 9 werden am zugeordneten bandseitigen Vertikalschenkel bzw. am unteren horizontalen Schenkel des Flügelrahmens angeschraubt. Die Verbindung des vertikalen längeren Winkelschenkels 11 des Tragwinkels 8 mit einem Lagerkörper 12 erfolgt über Niete 13, wobei es sich vorzugsweise um angeformte Nietzapfen des Lagerkörpers 12 handelt. Eine Bohrung 14 des lagerkörpers 12 sowie eine damit fluchtende Bohrung am oberen Ende des vertikalen Winkelschenkels 11 dient zum Durchtritt einer Befestigungsschraube. Weitere Befestigungsbohrungen sind gemäß Fig. 1 der Zeichnung an den beiden Tragwinkeln 8 und 9 vorgesehen.The bearing of the embodiment is used in particular for storing a comparatively heavy leaf of a window or a door on a frame. As a result, it is designed as a reinforced version with support brackets 8 and 9. In extension of the short angle leg of the support bracket 8, a lower support arm 10 made in one piece extends with it screwed lower horizontal leg of the casement. The connection of the vertical, longer angle leg 11 of the support bracket 8 to a bearing body 12 takes place via rivets 13, which are preferably molded-on rivet pins of the bearing body 12. A bore 14 of the bearing body 12 and a bore aligned therewith at the upper end of the vertical angle leg 11 serve for the passage of a fastening screw. Further mounting holes are provided on the two support brackets 8 and 9 as shown in FIG. 1 of the drawing.

An den Lagerkörper 12 schließt sich ein winkel-oder bogenförmiger Lageransatz 15 an, an welchem der kurze Winkelschenkel des Tragwinkels 9 unten unmittelbar anliegt. Die Verbindung zwischen diesen drei Teilen erfolgt durch Nieten.The bearing body 12 is adjoined by an angular or arcuate bearing projection 15, on which the short angle leg of the support bracket 9 bears directly below. The connection between these three parts is made by rivets.

Die Lagerhülse 2 ist ein Teil des Lagerkörpers 12. Sie ist mit Hilfe eines Querschlitzes 16 in zwei, vorzugsweise ungleich lange Teile unterteilt, wobei der kürzere untere Teil in der Art einer Klemmhülse 17 ausgebildet ist. Man erreicht dies mit Hilfe eines Vertikalschlitzes 18, der annähernd radial zur Lagerbohrung 19 verläuft. Er erstreckt sich von der in Fig. 2 links gelegenen vertikalen Fläche 20 des Lagerkörpers 12 bis zur Bohrung 21 der Lagerhülse 2. In letzterer befindet sich ein hülsenförmiger Bremsring 22. Der Querschlitz 16 erstreckt sich über etwa die Hälfte des Lagerkörpers 12, wie man Fig. 2 der Zeichnung deutlich entnehmen kann. Demnach verläuft sein inneres Ende 23 etwa durch die geometrische Zapfen- bzw. Lagerachse 5. Beim Ausführungsbeispiel verlaufen der Quer- und der Längsschlitz senkrecht zueinander, wobei sich der Querschlitz senkrecht zur geometrischen Achse 5 erstreckt, während der Längsschlitz in Richtung der geometrischen Zapfenachse 5 und parallel zur Flügelebene verläuft. Durch die beschriebene Ausbildung des Lagerkörpers 12 kann dieser einstückig und damit preisgünstig gefertigt werden.The bearing sleeve 2 is part of the bearing body 12. It is divided into two, preferably of unequal lengths, with the aid of a transverse slot 16, the shorter lower part being designed in the manner of a clamping sleeve 17. This is achieved with the aid of a vertical slot 18 which extends approximately radially to the bearing bore 19. It extends from the vertical surface 20 of the bearing body 12 on the left in FIG. 2 to the bore 21 of the bearing sleeve 2. In the latter there is a sleeve-shaped brake ring 22. The transverse slot 16 extends over approximately half of the bearing body 12, as can be seen in FIG 2 can clearly be seen in the drawing. Accordingly, its inner end 23 runs approximately through the geometric pin or bearing axis 5. In the exemplary embodiment, the transverse and longitudinal slots run perpendicular to one another, the transverse slot extending perpendicular to the geometric axis 5, while the longitudinal slot in the direction of the geometric pin axis 5 and runs parallel to the wing plane. Due to the described design of the bearing body 12, it can be manufactured in one piece and thus inexpensively.

Am hülsenförmigen Bremsring 22 befindet sich außen eine radial abstehende, in Richtung seiner Achse erstreckende, vorzugsweise angeformte Feder 24, die in eine Innennut 25 der Klemmhülse 17 und damit auch des Lagerkörpers 12 eingreift. Dadurch ist der Bremsring drehfest in der Lagerhülse 2 behalten. Wenn man auf ein entsprechendes Spiel im Nut- und Federbereich verzichtet, so kann der Bremsring dadurch auch in axialer Richtung gehalten werden. Gegenüberliegend, also um 180° am Umfang versetzt, ist der sich über die gesamte Länge erstreckende Schlitz 26 des hülsenförmigen Bremsrings 22. Er ermöglicht das Verengen und Aufweiten des Querschnitts der Lagerbohrung 19.On the sleeve-shaped brake ring 22 there is a radially projecting spring 24, which is preferably formed on and extends in the direction of its axis and which engages in an inner groove 25 of the clamping sleeve 17 and thus also of the bearing body 12. As a result, the brake ring is retained in the bearing sleeve 2 in a rotationally fixed manner. If one does without a corresponding play in the tongue and groove area, the brake ring can also be held in the axial direction. Opposite, i.e. offset by 180 ° on the circumference, is the slot 26 of the sleeve-shaped brake ring 22, which extends over the entire length. It enables the cross section of the bearing bore 19 to be narrowed and widened.

Das Verengen der Lagerbohrung erfolgt durch Eindrehen einer Klemmschraube 27 in ein Gewinde 28 des Lagerkörpers 12. Es befindet sich genau gesagt in dem in Fig. 2 oberhalb des Längsschlitz 18 gelegenen Teilstück des Lagerkörpers. Das darunter liegende Teilstück besitzt eine abgesetzte Bohrung 29 zum Durchstecken der Klemmschraube 27, wobei sich im erweiterten Bohrungsteil der Kopf der als Innensechskantschraube ausgebildeten Klemmschraube befindet. Das Eindrehen der letzteren bewirkt nicht nur eine Verengung des Längsschlitzes 18, sondern auch der Lagerhülsenbohrung 21. Diese Verengung überträgt sich auf den satt daran anliegenden hülsenförmigen Bremsring 22, so daß sich dessen Längsschlitz 26 verengt. Demnach ist die gesamte Verengung der Lagerbohrung 19 und damit auch die Reduzierung des Lagerspiels vorzugsweise durch die Breite des Längsschlitzes 26 des hülsenförmigen Bremsrings 22 bestimmt.The bearing bore is narrowed by screwing a clamping screw 27 into a thread 28 of the bearing body 12. It is located, to be precise, in the section of the bearing body located above the longitudinal slot 18 in FIG. 2. The section below it has a stepped bore 29 for inserting the clamping screw 27, the head of the clamping screw designed as an Allen screw being located in the enlarged bore part. The screwing in of the latter causes not only a narrowing of the longitudinal slot 18, but also of the bearing sleeve bore 21. This narrowing is transferred to the sleeve-shaped brake ring 22 which fits snugly against it, so that its longitudinal slot 26 narrows. Accordingly, the overall narrowing of the bearing bore 19 and thus also the reduction in the bearing play is preferably determined by the width of the longitudinal slot 26 of the sleeve-shaped brake ring 22.

Fig. 2 entnimmt man, daß die Längsachse der Innennut 25 des Lagerkörpers 12 mit dem Längsschlitz 18 und damit auch dem Inneren Ende des Querschlitzes einen Winkel von vorzugsweise etwa 45° einschließt, wobei die Innennut gegen das Gewinde 28 für die Klemmschraube 27 weist.Fig. 2 reveals that the longitudinal axis of the inner groove 25 of the bearing body 12 with the longitudinal slot 18 and thus also the inner end of the transverse slot encloses an angle of preferably approximately 45 °, the inner groove pointing against the thread 28 for the clamping screw 27.

In eine Bohrung am in Gebrauchslage oberen Ende der Lagerhülse 2 ist ein Gewindebolzen 31 eingedreht, dessen unteres, insbesondere abgesetztes zapfenförmiges Ende in eine entsprechende Bohrung eines Lagerstücks 30 eingreift. Dieses besitzt an seinem nach unten weisenden Ende eine kalottenförmige Ausnehmung 32, Daran liegt das ballige Ende des Lagerzapfens an. Mit Hilfe dieser Einrichtung kann man den Flügel im Bereich des bandseitigen unteren Endes gegenüber dem festen Rahmen in Höhenrichtung einstellen.A threaded bolt 31 is screwed into a bore at the upper end of the bearing sleeve 2 in the position of use, the lower, in particular stepped, pin-shaped end of which engages in a corresponding bore of a bearing piece 30. This has a dome-shaped recess 32 at its downward-facing end. The spherical end of the bearing journal bears against it. With the help of this device, the sash can be adjusted in the height direction in the area of the hinge-side lower end relative to the fixed frame.
