Abstract

A concealed lower corner bearing intended for turn, especially turn-and-tilt windows, doors or the like is equipped with a link mechanism (3), which is arranged between the wing lower edge and the lower transverse spar of the fixed frame (1) and which, during the turn-opening of the wing (2), causes a displacement of the axis of rotation of the wing occurring transversely relative to the wing plane, and furthermore with a supporting bar (11) which is arranged between the fixed frame (1) and the wing (2) in the region of the axis of rotation and which is supported with its lower end (11') on the fixed frame (1) and cooperates in carrying the wing (2) in the region of the axis of rotation. To prevent the wing (2) from sagging when it is being turn-opened, the supporting bar (11), guided vertically displaceably at its upper end on the wing frame (2) and designed as a supporting scissor mechanism, is equipped with a suspension link (12) which is articulated approximately centrally on it and from the lower end (12') of which the wing frame (2) is suspended. <IMAGE>

Description

Die Erfindung bezieht sich auf ein verdeckt liegendes unteres Ecklager für Dreh-, insbesondere Dreh/Kipp-Fenster, -Türen od.dgl., mit einem zwischen der Flügelunterkante und dem unteren Querholm des feststehenden Rahmens angeordneten, beim Drehöffnen des Flügels eine quer zur Flügelebene erfolgende Verlagerung der Flügeldrehachse bewirkenden Lenkergestänge und einem zwischen dem festen Rahmen und Flügel im Drehachsbereich angeordneten, sich im wesentlichen in dessen Längsrichtung erstreckenden Arm.The invention relates to a concealed lower corner bearing for pivoting, in particular pivoting / tilting windows, doors or the like, with an arranged between the lower edge of the wing and the lower cross member of the fixed frame, when opening the wing, one transverse to the wing plane subsequent displacement of the wing pivot axis effecting linkage and an arranged between the fixed frame and wing in the pivot axis area, extending substantially in the longitudinal direction of the arm.

Ein verdeckt liegendes unteres Ecklager obiger Art ist aus DE-U-89 07 630 bekannt.A concealed lower corner bearing of the above type is known from DE-U-89 07 630.

Der Erfindung liegt die Aufgabe zugrunde, ein Ecklager der eingangs erwähnten Gattung zu schaffen, das bei einfacher Bauart ein Verlagerung des Flügels in vertikaler Richtung bei dessen Drehöffnen sicher verhindert.The invention has for its object to provide a corner bearing of the type mentioned, which is easier Design reliably prevents the sash from moving in the vertical direction when it opens.

Diese Aufgabe wird ausgehend von einem gattungsgemäßen Ecklager erfindungsgemäß durch den kennzeichnenden Teil des Anspruchs 1 gelöst.This object is achieved on the basis of a generic corner bearing according to the invention by the characterizing part of claim 1.

Auf diese Weise kommt es beim Drehöffnen des Flügels zu keiner vertikalen verlagerung des Flügels, da die Aufhängestelle des Flügels am unteren Ende des Hängelenkers lediglich eine Horizontalverlagerung gegenüber dem unteren Ende des Stützstabes erfährt.In this way, there is no vertical displacement of the wing when the wing is opened, since the suspension point of the wing at the lower end of the hanging link only undergoes a horizontal shift relative to the lower end of the support rod.

Vorteilhaft ist der Stützstab an seinem unteren Ende lagerzapfenartig zugespitzt und darüber in einem an einer Festrahmenschiene an deren der Drehachse zugewandtem Ende sitzenden Lagertopf kugelgelenkig abgestützt, während der Hängelenker an seinem freien unteren Ende hakenartig ausgebildet und darüber in einer am drehachsseitigen Ende einer Flügelrahmenschiene nach oben abgewinkelt angebrachten Hakenöse eingehängt ist.The support rod is advantageously tapered at its lower end like a trunnion and above it is supported in a bearing pot on a fixed frame rail at its end facing the axis of rotation, while the hanging joint is hook-like at its free lower end and angled upwards in one at the end of a sash frame rail on the axis of rotation attached hook eye is hooked.

Das mit der neuen Abstützschere zusammenwirkende Lenkergestänge ist vorteilhaft von der durch Anspruch 8 der DE-PS 21 13 665 bekannten Bauart, nämlich mit einem am unteren Querholm des feststehenden Rahmens drehachsnah unverschieblich angebrachten Traglenker und zwei damit gelenkig verbundenen, an der Flügelunterkante unverschieblich angelenkten Parallellenkern versehen, die zusammen mit dem Traglenker und der Flügelunterkante ein Lenkerparallelogramm bilden und wobei der eine Parallellenker über seine Gelenkverbindungsstelle am Tragarm zu einem Steuerarm verlängert ist, der mit seinem freien Ende in einem am festen Rahmen vorhandenen Führungsschlitz längsverschieblich geführt ist. Während jedoch bei der bekannten Lenkergestänge-Bauart der Steuerarm in Verlängerung des drehachsnah liegenden Parallellenkers und der Führungsschlitz für das freie Steuerarmende im Bereich des Traglenkers bzw. des Lenkerparallelogramms liegen und dadurch noch eine entsprechend breite Ecklager-Bauart bedingen, ist nach einem weiteren Merkmal der Erfindung der Steuerarm an dem von der Flügeldrehachse entfernt angeordneten Parallellenker vorhanden und der Führungsschlitz außerhalb des Schwenkbereichs des Traglenkers angeordnet.The interacting with the new support scissors handlebar linkage is advantageous of the type known from claim 8 of DE-PS 21 13 665, namely provided with a fixed on the lower cross member of the fixed frame near the axis of rotation fixed support arm and two articulated, articulated parallel to the lower edge of the wing articulated parallel link , which, together with the support arm and the lower edge of the wing, form a handlebar parallelogram, and the one parallel link is extended via its joint connection point on the support arm to a control arm which is guided with its free end in a guide slot provided on the fixed frame so as to be longitudinally displaceable. However, while in the known linkage design the control arm in the extension of the parallel link near the pivot axis and the guide slot for the free control arm end lie in the area of the support arm or the handlebar parallelogram and thereby still require a correspondingly wide corner bearing design, according to a further feature of the invention the control arm is present on the parallel link located at a distance from the wing axis of rotation and the guide slot is arranged outside the pivoting range of the support arm.

Auf diese Weise können sämtliche Teile des unteren Ecklager-Lenkergestänges in der Flügelschließstellung deckungsgleich untereinanderliegen, so daß das gesamte Ecklager dann so schmal ist, wie es der normalen Breite seiner einzelnen Lenker bzw. Arme entspricht. Hierdurch kann ein solches Lenkergestänge auch bei solche Schmalbauweisen erfordernden, mit Mitteldichtungen versehenen Kippschwenk-Fenstern ohne weiteres eingebaut werden.In this way, all parts of the lower corner bearing linkage in the wing closed position are congruent with each other, so that the entire corner bearing is then as narrow as it corresponds to the normal width of its individual links or arms. In this way, such a handlebar linkage can also be installed without any problems even in the case of such narrow construction methods which require tilt-and-pivot windows provided with center seals.

Das in Fig.1 abgebildete Dreh/Kipp-Fenster besteht aus dem feststehenden Rahmen 1 und dem darin angeschlagenen, sowohl um eine senkrechte Achse drehbaren als auch um eine untere horizontale Achse kippbaren Fensterflügel 2. Dazu ist der Flügel an seiner unteren drechachsseitigen Ecke über das in Fig.1 generell mit 3 bezeichnete Ecklager einerseits sowie über eine oben angeordnete, generell mit 4 bezeichnete Ausstellschere versehen bzw. darüber mit dem festen Rahmen 1 verbunden. Sowohl das untere Ecklager 3 als auch die obere Ausstellvorrichtung 4 sind, wie Fig.1 zeigt, vollständig verdeckt angeordnet, so daß von diesen Beschlagteilen von außen nichts zu sehen ist. Lediglich der für die Bedienung der Ausstellvorrichtung 4 über ein Treibstangengetriebe notwendige Betätigungsgriff 5 ist als Fensterbeschlagteil sichtbar und unmittelbar zugänglich. Die obere Ausstellvorrichtung 4 ist von herkömmlicher Beschaffenheit. Vorteilhaft wird dafür die durch die DE-OS 29 40 049 bekannte Schmalbauart verwendet.The rotating / tilting window shown in Fig.1 consists of the fixed frame 1 and the hinged window sash, which can be rotated both about a vertical axis and tiltable about a lower horizontal axis 2. For this purpose, the sash is at its lower corner on the roof side above the in Fig.1 generally designated 3 corner bearings on the one hand and provided with an above-arranged, generally designated 4 scissors or connected to the fixed frame 1 above. Both the lower corner bearing 3 and the upper one The opening device 4, as shown in FIG. 1, is arranged so that it is completely concealed, so that nothing can be seen from the outside of these fitting parts. Only the actuating handle 5 required for operating the opening device 4 via a connecting rod gear is visible as a window fitting part and is directly accessible. The upper display device 4 is of a conventional nature. The narrow construction known from DE-OS 29 40 049 is advantageously used for this.

Das untere Ecklager 3 besitzt ein Lenkergestänge, das beim Drehöffnen des Flügels 2 eine Verlagerung des unteren Endes seiner Drehachse quer zur Flügelebene bewirkt. Dieses Lenkergestänge ist insbesondere von der in Fig.2 deutlich erkennbaren Beschaffenheit. Es besteht aus der am unteren Querholm 1′ des festen Rahmens anzuschlagenden Festrahmenschiene 6, dem Traglenker 7, den beiden Parallellenkern 8 und 9 mit dem in dessen Verlängerung liegenden Steuerarm 9′ sowie der an der Unterkante des Flügels 2 anzuschlagenden Flügelrahmenschiene 10. Weiterhin gehören zum unteren Ecklager der entsprechend den Fig.3 und 4 im Drehachsbereich zwischen dem festen Rahmen 1 und dem Flügel 2 im Drehachsbereich angeordnete und sich im wesentlichen in dessen Längsrichtung erstreckende Stützstab 11 mit dem etwa mittig an ihm angelenkten Hängelenker 12, an dessen unterem Ende der Flügel 2 hängt.The lower corner bearing 3 has a linkage which, when the wing 2 is rotated, causes the lower end of its axis of rotation to be displaced transversely to the wing plane. This handlebar linkage is in particular of the nature clearly visible in FIG. It consists of the fixed frame rail 6 to be attached to the lower cross bar 1 'of the fixed frame 6, the supporting link 7, the two parallel link arms 8 and 9 with the control arm 9' located in its extension, and the sash frame rail 10 to be attached to the lower edge of the wing 2 3 and 4 in the pivot axis area between the fixed frame 1 and the wing 2 in the pivot axis area and essentially extending in the longitudinal direction of the support rod 11 with the approximately articulated hinge joint 12 at its lower end, at the lower end of the wing 2 hangs.

Der Traglenker 7 ist mit seinem einen Ende drehachsnah über den Bolzen 13 auf der Festrahmenschiene 6 unverschieblich angelenkt und mit seinem anderen Ende über den Gelenkbolzen 14 mit dem Steuerarm 9′ bzw. dem Parallellenker 9 gelenkig verbunden. Weiterhin ist auch der Parallellenker 8 mit dem Traglenker 7 über den Anlenkbolzen 14′ gelenkig verbunden. Über die Gelenkbolzen 15,16 sind die Parallellenker 8,9 an der Flügelrahmenschiene 10 unverschieblich angelenkt. Die Parallellenker 8,9 bilden zusammen mit dem Traglenker 7 und der Flügelrahmenschiene 10 ein Lenkerparallelogramm.The support arm 7 is articulated with its one end near the axis of rotation via the pin 13 on the fixed frame rail 6 and with its other end via the hinge pin 14 with the control arm 9 'and the parallel link 9 articulated. Furthermore, the parallel link 8 is articulated with the support arm 7 via the pivot pin 14 '. The parallel links 8, 9 are articulated immovably on the casement rail 10 via the hinge pins 15, 16. The parallel link 8.9 together with the support link 7 and the sash rail 10 form a link parallelogram.

Auf der Festrahmenschiene 6 ist außerhalb des Schwenkbereichs des Traglenkers 7 ein Führungsschlitz 17 vorgesehen, in welchem das festrahmenseitige Ende 9˝ des Steuerarms über den Gelenkführungsstift 18 längsverschieblich geführt ist. Auf diese Weise werden die Flügelrahmenschiene 10 und damit auch der Flügel während seiner Drehöffnungsbewegung im Zusammenwirken mit dem Traglenker 7 so gesteuert, daß die untere Flügelecke eine annähernde Kreisbewegung um die fiktive Drehachse des Flügels beschreibt.A guide slot 17 is provided on the fixed frame rail 6 outside the pivoting range of the supporting link 7, in which the fixed frame side end 9˝ of the control arm is guided in a longitudinally displaceable manner via the articulation guide pin 18. In this way, the sash rail 10 and thus the wing are controlled during its rotary opening movement in cooperation with the support arm 7 so that the lower wing corner describes an approximate circular movement about the fictitious axis of rotation of the wing.

Auf der Festrahmenschiene 6 ist an der Außenkante eine nach oben vorstehende Anschlagleiste 6′ vorgesehen, an der in der Flügelschließstellung der Traglenker 7 sowie die beiden Parallellenker 8,9 anliegen. Weiterhin sind auf der Oberseite der Flügelrahmenschiene 10 noch von Befestigungsschraublöchern 19 durchsetzte Befestigungsköpfe 20 vorhanden, die in eine an der Flügelrahmenunterkante vorhandene Nut eingreifen und für eine sichere Befestigung der Schiene 10 am Flügel sorgen.On the fixed frame rail 6, an upwardly projecting stop bar 6 'is provided on the outer edge, on which in the wing closed position of the support arms 7 and the two parallel links 8, 9 lie. Furthermore, on the upper side of the sash rail 10 there are fastening heads 20 which are penetrated by fastening screw holes 19 and which engage in a groove provided on the lower edge of the sash frame and ensure secure fastening of the rail 10 to the sash.

Der Stützstab 11 und der an ihm etwa mittig angelenkte Hängelenker 12 bilden eine Abstützschere, die wesentlich zur Abtragung des Flügelgewichts im Drehachsbereich beiträgt, so daß die Lenker 7,8,9 und 9′ des Eckgelenks davon wesentlich entlastet bleiben. Sowohl der Stützstab 11 als auch der Hängelenker 12 bestehen aus entsprechend gestanztem Flachmaterial, wobei der Hängelenker zu einem U-förmigen, den Stützstab 11 umgreifenden Gabelprofil geformt ist.The support rod 11 and the approximately articulated hinge 12 form a scissor stay, which contributes significantly to the removal of the sash weight in the pivot area, so that the handlebars 7,8,9 and 9 'of the corner joint remain substantially relieved. Both the support rod 11 and the hanging joint 12 consist of correspondingly punched flat material, the hanging joint being shaped into a U-shaped fork profile encompassing the supporting rod 11.

Der Stützstab 11 ist an seinem unteren Ende 11′ lagerzapfenartig zugespitzt und darüber in einem an der Festrahmenschiene 6 an deren der Drehachse zugewandtem Ende sitzenden Lagertopf 21 kugelgelenkig abgestützt. An seinem oberen Ende besitzt der Stützstab 11 einen aus Kunststoff bestehenden Gleitkopf 22, der in einer am Flügelrahmen 2 vorhandenen Führungsschiene 23 höhen- und gleitverschieblich geführt ist.The support rod 11 is tapered at its lower end 11 'like a trunnion and above it is supported in a spherical joint on a fixed frame rail 6 at its end facing the axis of rotation at the end of the bearing pot 21. At its upper end, the support rod 11 has a sliding head 22 made of plastic, which is guided in a guide rail 23 provided on the sash frame 2 so that it can slide and slide.

Der Hängelenker 12 ist an seinem unteren Ende hakenartig ausgebildet und darüber in die am drehachsseitigen Ende der Flügelrahmenschiene 10 nach oben abgewinkelt angebrachte Hakenöse 24 eingehängt. Da der Hängelenker 12 ein Gabelprofil besitzt, sind an dessen freien Schenkelenden zur Bildung der Einhängehaken 12′ T-profilförmige Einschnitte 12˝ vorgesehen, während am drehachsseitigen Ende der Flügelrahmenschiene 10 die hier vorhandene Halteöse 24 mit zwei entsprechend nebeneinander liegenden Ösenschlitzen versehen ist.The hanging joint 12 is hook-shaped at its lower end and is hooked above it into the hook eye 24, which is attached at the pivot axis end of the sash frame 10 and is angled upward. Because the hanging joint 12 has a fork profile owns, are provided at its free leg ends to form the hook 12 'T-shaped incisions 12˝, while at the pivot axis end of the sash rail 10, the retaining eyelet 24 provided here is provided with two eyelet slots lying side by side.

Da die aus dem Stützstab 11 und dem Hängelenker 12 bestehende Abstützschere während der Flügel-Drehöffnungsbewegung zwar bezüglich des Stützstabes 11 eine entsprechende Kippbewegung vollführt, wie das insbesondere Fig.3 erkennen läßt, und damit auch die Anlenkstelle 25 zwischen dem Stützstab 11 und dem Hängelenker 12 eine entsprechende Verlagerung nach unten erfährt, wird diese jedoch durch die dabei erfolgende entgegengesetzte Schwenkbewegung des Hängelenkers 12 zugleich kompensiert, so daß das untere Ende des Hängelenkers 12 eine Horizontalverlagerung erfährt, mithin auch der Flügel 2 drehachsseitig nicht abzusacken vermag.Since the support scissors consisting of the support rod 11 and the suspension arm 12 perform a corresponding tilting movement with respect to the support rod 11 during the wing rotation opening movement, as can be seen in particular in FIG. 3, and thus also the articulation point 25 between the support rod 11 and the suspension arm 12 undergoes a corresponding shift downwards, but this is at the same time compensated for by the opposite pivoting movement of the hanging link 12, so that the lower end of the hanging link 12 undergoes a horizontal shift, and consequently the wing 2 cannot sag on the rotary axis side.

Im Rahmen der vorliegenden Erfindung sind mancherlei Abwandlungen möglich. So können anstelle des dargestellten unteren Ecklager-Lenkergestänges grundsätzlich auch andere bekannte Lenkergestänge verwendet werden, die beim Drehöffnen des Flügels eine entsprechende Verlagerung seiner Drehachse bewirken.Various modifications are possible within the scope of the present invention. So instead of the lower corner bearing linkage shown, other known linkage can be used, which cause a corresponding displacement of its axis of rotation when opening the wing.
