Definitions

  • the invention relates to an opening device for an at least parallel and horizontally displaceable wing of a window, a door or the like.
  • a releasable locking device for at least the lower extension arm or arms in the parallel storage position, which consists of a control arm assigned to the extension arm in the area of the carriage or carriages, which has a control bracket with an abutment seated on the fixed frame the sliding-closing movement of the wing can be brought into and out of operative connection, in which the control arm on the carriage is only limitedly pivotably mounted on the horizontal plane and is designed as a two-armed lever, and in which the locking member a sits in the free end of the lever arm leading in the sliding closing direction of the wing.
  • the control arm which is mounted on the carriage so that it can be pivoted to a limited extent, acts directly as a support member via the second lever arm, which is directed away from the lever arm carrying the locking member, at an obtuse angle.
  • the forces acting in the closing direction on the sash located in the parallel storage position are thereby introduced in a form-fitting but asymmetrical manner on the one hand via the pivot bearing of the raising arm and on the other hand via the pivoting bearing of the control arm spaced therefrom for mounting the rollers in the carriage.
  • the extension arm on the lower wing cross member has a freely rotatable mounting, the force effects transmitted to the carriage are introduced asymmetrically to its rollers in the frame-side, stationary running rail. This can not only result in undesirable deformations on the running rail, but there is also the possibility that the running rollers of the carriages rise on the rounded profile of the guide web of the running rail and then get out of guiding engagement therewith.
  • control arm mounted on the carriage and designed as a support lever constantly interacts with the running rail for the carriage until the sash reaches the sliding closing position. It is only here that the control shoulder and thus the control arm for the extension arms are free, so that the sash can subsequently be moved into its closed position on the fixed frame by means of the extension arms.
  • the invention has for its object to provide an opening device of the type described above, the extending arm cooperating with the locking device is positively supported or locked in its pivot position corresponding to the parallel storage position against the wing, without the function of the releasable locking device in the interaction of its control approach with the abutment sitting on the fixed frame is impaired during the sliding-closing movement of the wing.
  • the opening arm forms a quadrilateral joint with the second lever arm of the control arm, the connecting bracket and the additional arm, via which the actuating movement of the control arm of the locking device and the additional arm of the opening device are brought into mutual dependence, namely in the Way that the additional arm on the wing is engaged in the locking catch when the extension arm comes out of engagement with the frame-side abutment, while conversely the additional arm disengages from the wing-side locking catch after the control arm has come into engagement in the frame-side abutment.
  • This positive coupling ensures that the parallel displacement of the wing relative to the fixed frame can only be initiated when the wing has been brought completely into its parallel storage position. The sash can only leave its parallel storage position again after it has been pushed back into the relative position to the fixed frame necessary for its proper closing.
  • the deployment arms are securely fixed in their parallel storage position by the releasable locking device during the movement of the wing in the sliding-closing direction until the control shoulder of the control arm in the area of the sliding-closing movement of the wing with the abutment on fixed frame comes into operative connection and from this a feedback movement controlled in a certain way for the wing latching additional arm is derived.
  • the wing-side latch for the additional arm is stressed in the blocking sense or in the sense of a positive locking of the extension arm against the wing.
  • control arm is mounted on the carriage approximately in the aligned position of the articulation point of the extension arm.
  • the two lever arms of the control arm can be arranged at an obtuse angle to one another, the joint between its second lever arm and the connecting plate when the wing is in the closed position with the joint of the extension arm on the wing on an approximately parallel plane to the fixed frame.
  • a design has proven itself according to claim 4, according to which the fixed stop on the fixed frame has the shape of an arcuously curved claw, the outlet and inlet opening of which is closer to the plane of the fixed frame than its closed end section.
  • the functional reliability of the opening device according to the invention can also be improved in that, according to claim 5, the control arm is acted upon in the blocking direction by a prestressing force, in particular a spring.
  • the invention provides that the locking receptacle is inclined against the guide slot and its angle of inclination has at least approximately cover position with an arc of curvature, the center of which coincides with the joint of the additional arm on the extension arm located relative to the wing in the parallel storage position. It is particularly expedient according to claim 7 when the latching receptacle is provided on the wing with its end facing away from the fixed frame.
  • a measure of the invention which further improves the functional reliability of the opening device is also seen according to claim 8 in that the wing-side ends of the additional arms of both opening devices can be moved synchronously with one another, e.g. are coupled via a push rod.
  • a particularly advantageous design of an opening device according to the invention is characterized according to claim 9 by two with their extension arm and their additional arm and the associated wing-side bearing block mirror-image to each other and by a differential coupling gear via which the pivotally guided ends of the wing arms of the additional arms can be connected to each other in opposite directions so as to be positively movable are.
  • An opening device designed in this way can be used in one and the same embodiment both for leaves of windows and doors that can be horizontally displaced in the opening direction from the closed position to the right and to the left, the opening devices cooperating with the leaf in the manner of a so-called trapezoidal link system, which ensures exact parallel displacement of the wing is beneficial across its plane.

Abstract

A disengaging device which is constructionally simple and operationally reliable for a wing of a window, door or the like which is required to take up a configuration parallel and disengaged from a stationary frame in order to be slidable horizontally for opening and closing. The wing is connected to the frame with upper and lower swingout arms in pairs. The lower swingout arms are each pivotally mounted at the lower transverse wing bar at one end and to a traveling carriage at the other end. A releasable blocking device is provided for the lower swing out arms which is activated when they are in the disengaged and stable parallel position. The blocking device is activated through a control arm associated with the lower traveling carriages. The control arm can be brought into and out of operative connection with a thrust bearing located on the stationary frame. The control arm is mounted on the traveling carriage and limited to basically horizontal planar motion in a limitedly swivelable manner. It is configured as a two armed lever. At the free end of the first lever arm, which runs and extends in the direction in which the wing is closed, a locking link is provided. At the free end of the other lever arm, a connection lashing is articulated. An additional arm is pivoted to the swingout arm at one end and at the other end engages by means of a pinion in a swivelable and movable manner in a guide slot formed in a bearing surface in the wing. At the end of the guide slot, an uptake notch is provided which accepts the pinion of the additional arm when the device is in the parallel stop position. This connection lashing is connected in a swivelable manner to the additional arm, the connection being made between its joint with the swingout arm and the pinion end, thereby coupling its motion with that of the control arm 23.

Description

Die Erfindung betrifft eine Ausstellvorrichtung für einen zumindest parallelabstellbaren und in dieser Lage horizontal verschiebbaren Flügel eines Fensters, einer Tür od. dgl. mit unten Ausstellarmen und oberen Ausstellarmen, bei welcher zumindest der oder die unteren Ausstellarme einerseits am unteren Flügelquerholm und andererseits an einem bzw. je einem Laufwagen jeweils drehbar gelagert sind, mit einer auslösbaren Sperrvorrichtung für wenigstens den oder die in Parallelabstellage befindlichen unteren Ausstellarme, die aus einem im Bereich des oder der Laufwagen dem Ausstellarm zugeordneten Steuerarm besteht, der über einen Steueransatz mit einem am feststehenden Rahmen sitzenden Widerlager durch die Schiebe-Schließendbewegung des Flügels in und außer Wirkverbindung bringbar ist, bei welcher der Steuerarm am Laufwagen etwa auf horizontaler Ebene ausschließlich begrenzt schwenkbeweglich gelagert sowie als zweiarmiger Hebel ausgebildet ist, und bei welcher das Riegelglied am freien Ende des in Schiebe-Schließrichtung des Flügels vorlaufenden Hebelarms sitzt.The invention relates to an opening device for an at least parallel and horizontally displaceable wing of a window, a door or the like. With lower raising arms and upper raising arms, in which at least the lower raising arm or arms on the one hand on the lower wing cross member and on the other hand on or one carriage each is rotatably supported, with a releasable locking device for at least the lower extension arm or arms in the parallel storage position, which consists of a control arm assigned to the extension arm in the area of the carriage or carriages, which has a control bracket with an abutment seated on the fixed frame the sliding-closing movement of the wing can be brought into and out of operative connection, in which the control arm on the carriage is only limitedly pivotably mounted on the horizontal plane and is designed as a two-armed lever, and in which the locking member a sits in the free end of the lever arm leading in the sliding closing direction of the wing.

Ein Beschlag dieser Art ist bereits bekannt durch das DE-GM 84 35 367.A fitting of this type is already known from DE-GM 84 35 367.

Der am Laufwagen begrenzt schwenkbeweglich gelagerte Steuerarm wirkt hierbei über den stumpfwinklig von dem das Riegelglied tragenden Hebelarm weggerichteten, zweiten Hebelarm unmittelbar mit dem ihm benachbarten, in Parallelabstellage befindlichen unteren Ausstellarm als Stützglied zusammen. Die auf den in Parallelabstellage befindlichen Flügel im Schließsinne einwirkende Kräfte werden dadurch einerseits über das Drehlager des Ausstellarms sowie andererseits über das hiervon beabstandete Schwenklager des Steuerarms formschlüssig, aber unsymmetrisch zur Lagerung der Laufrollen in den Laufwagen eingeleitet.The control arm, which is mounted on the carriage so that it can be pivoted to a limited extent, acts directly as a support member via the second lever arm, which is directed away from the lever arm carrying the locking member, at an obtuse angle. The forces acting in the closing direction on the sash located in the parallel storage position are thereby introduced in a form-fitting but asymmetrical manner on the one hand via the pivot bearing of the raising arm and on the other hand via the pivoting bearing of the control arm spaced therefrom for mounting the rollers in the carriage.

Da andererseits der Ausstellarm am unteren Flügelquerholm eine frei drehbewegliche Lagerung hat, werden die auf den Laufwagen übertragenen Kraftwirkungen unsymmetrisch zu dessen Laufrollen in die rahmenseitige, ortsfeste Laufschiene eingeleitet. Hieraus können sich aber nicht nur unerwünschte Verformungen an der Laufschiene ergeben, sondern es besteht auch die Möglichkeit, daß die Laufrollen der Laufwagen am abgerundeten Profil des Führungssteges der Laufschiene hochsteigen und dann mit diesem außer Führungseingriff gelangen.On the other hand, since the extension arm on the lower wing cross member has a freely rotatable mounting, the force effects transmitted to the carriage are introduced asymmetrically to its rollers in the frame-side, stationary running rail. This can not only result in undesirable deformations on the running rail, but there is also the possibility that the running rollers of the carriages rise on the rounded profile of the guide web of the running rail and then get out of guiding engagement therewith.

Die gleichen Unzulänglichkeiten ergeben sich auch bei dem Beschlag nach der DE-OS 32 34 677, bei welchem mit dem Ausstellarm ein Zusatzarm lediglich schwenkbeweglich in Verbindung steht, der andererseits mit einem Zapfen schwenkverschieblich in einen Führungsschlitz am Laufwagen eingreift, wobei dieser Führungsschlitz für den Zapfen des Zusatzarmes an dem der Parallelabstellage des Flügels zugeordneten Ende eine Rastaufnahme aufweist.The same shortcomings also arise with the fitting according to DE-OS 32 34 677, in which an additional arm is only pivotally connected to the extension arm, which on the other hand swivels with a pin in a guide slot on the carriage, this guide slot for the pin of the additional arm has a catch at the end assigned to the parallel storage position of the wing.

Da auch in diesem Falle die Rastaufnahme für den Zapfen des Zusatzarms einen beträchtlichen Abstand vom Drehlager des Ausstellarms am Laufwagen hat und der Führungsschlitz sich in einem in Schiebe-Schließrichtung des Flügels auskragenden, dornartigen Fortsatz des Laufwagens befindet, treten hier die beim Beschlag nach dem DE-GM 84 35 367 gegebenen Unzulänglichkeiten in noch höherem Maße in Erscheinung.Since the catch for the pin of the additional arm is also at a considerable distance from the pivot bearing of the extension arm on the carriage in this case and the guide slot is located in a thorn-like extension of the carriage which projects in the sliding-closing direction of the wing, here the fitting occurs according to DE -GM 84 35 367 given shortcomings in an even greater degree.

Bei dem durch die US-PS 2 741 807 bekannt gewordenen Beschlag treten die vorstehend aufgezeigten Unzulänglichkeiten zwar nicht auf, weil dort der als Stützhebel ausgebildete Steuerarm, bedingt durch seine am Flügel in Fluchtlage mit dem Ausstellarm vorgesehene Schwenklagerung, die auf den parallel abgestellten Flügel quer zu seiner Ebene ausgeübten Kraftwirkungen unter Umgehung des Laufwagens unmittelbar in den feststehenden Rahmen einleiten kann. Das ist aber nur dann möglich, wenn der Steuerarm jeweils über die Gesamtlänge des horizontalen Verschiebeweges für den Flügel hinweg mit einem rahmenseitig bzw. ortsfest eingebauten, schienenförmigen Widerlager zusammenwirkt, über das dann die Parallelabstellage der Ausstellarme in jeder möglichen Schiebestellung durch den Steuerarm gesichert werden kann.In the case of the fitting disclosed by US Pat. No. 2,741,807, the above-mentioned shortcomings do not occur because there the control arm designed as a support lever, due to its swivel mounting provided on the wing in alignment with the extension arm, transversely on the wing placed in parallel can exert force effects exerted on its level bypassing the carriage directly into the fixed frame. However, this is only possible if the control arm interacts with a rail-side abutment installed on the frame or stationary over the entire length of the horizontal displacement path for the sash, by means of which the control arm can then secure the parallel parking position of the extension arms in any possible sliding position .

Beim Beschlag nach der FR-PS 1 551 381 wirkt der am Laufwagen gelagerte und als Stützhebel ausgebildete Steuerarm ständig mit der Laufschiene für den Laufwagen zusammen, bis der Flügel die Schiebe-Schließendstellung erreicht. Erst hier wird der Stueuransatz und damit der Steurarm für die Ausstellarme frei, so daß nachfolgend der Flügel mittels der Ausstellarme in seine Schließlage am feststehenden Rahmen bewegt werden kann.When fitting according to FR-PS 1 551 381, the control arm mounted on the carriage and designed as a support lever constantly interacts with the running rail for the carriage until the sash reaches the sliding closing position. It is only here that the control shoulder and thus the control arm for the extension arms are free, so that the sash can subsequently be moved into its closed position on the fixed frame by means of the extension arms.

Allen vorstehend erläuterten, bekannten Beschlägen ist der Nachteil eigentümlich, daß die drehbewegliche Verbindung des mit der auslösbaren Sperrvorrichtung zusammenwirkenden Ausstellarms mit dem Flügel auch in dessen Parallelabstellage erhalten bleibt und dadurch Winkelverlagerungen dieses Ausstellarms relativ zum Flügel in dessen Parallelabstellage nicht wirksam unterbunden werden können.All of the known fittings described above have the disadvantage that the rotatable connection of the extending arm cooperating with the releasable locking device with the wing is retained even in its parallel storage position, and as a result angular displacements of this raising arm relative to the wing in its parallel parking position cannot be effectively prevented.

Der Erfindung liegt die Aufgabe zugrunde, eine Ausstellvorrichtung der anfangs erläuterten Gattung zu schaffen, deren mit der Sperrvorrichtung zusammenarbeitender Ausstellarm in seiner der Parallelabstellage entsprechenden Schwenkstellung formschlüssig gegen den Flügel abgestützt bzw. verriegelt ist, ohne daß hierdurch die Funktion der auslösbaren Sperrvorrichtung beim Zusammenwirken ihres Steueransatzes mit dem am feststehenden Rahmen sitzenden Widerlager bei der Schiebe-Schließendbewegung des Flügels beeinträchtigt ist.The invention has for its object to provide an opening device of the type described above, the extending arm cooperating with the locking device is positively supported or locked in its pivot position corresponding to the parallel storage position against the wing, without the function of the releasable locking device in the interaction of its control approach with the abutment sitting on the fixed frame is impaired during the sliding-closing movement of the wing.

Die Lösung dieser Aufgabe wird erfindungsgemäß nach den Kennzeichnungsmerkmalen des Anspruchs 1 dadurch erreicht,

  • daß mit dem Ausstellarm ein Zusatzarm lediglich schwenkbeweglich in Verbindung steht, der mit einem Zapfen schwenkverschieblich in einen Führungsschlitz am Flügel eingreift,
  • daß für den Zapfen des Zusatzarmes an dem der Parallelabstellage des Flügels zugeordneten Ende des Führungsschlitzes eine Rastaufnahme vorgesehen ist,
  • daß am freien Ende des zweiten Hebelarms des Steuerarms eine Verbindungslasche angelenkt ist, und daß die Verbindungslasche am Zusatzarm im Bereich zwischen dem Zapfen und dem Gelenk am Ausstellarm lediglich schwenkbeweglich angreift und eine Zwangsbewegungs-Kopplung mit dem Steuerarm bildet.
According to the invention, this object is achieved according to the characterizing features of claim 1 by
  • that an additional arm is only pivotally connected to the extension arm and engages with a pin pivotably in a guide slot on the wing,
  • that a snap-in receptacle is provided for the pin of the additional arm at the end of the guide slot assigned to the parallel storage position of the wing,
  • that a connecting strap is articulated at the free end of the second lever arm of the control arm, and that the connecting strap on the additional arm in the region between the pin and the joint on the extension arm only swivels and forms a forced movement coupling with the control arm.

Vorteilhaft bei dieser Ausbildung einer Ausstellvorrichtung ist, daß der Ausstellarm mit dem zweiten Hebelarm des Steuerarms, der Verbindungslasche und dem Zusatzarm ein Gelenkviereck bildet, über das die Stellbewegung des Steuerarms der Sperrvorrichtung sowie des Zusatzarms der Ausstellvorrichtung in gegenseitige Abhängigkeit gebracht sind, und zwar in der Weise, daß der Zusatzarm am Flügel in die Sperrast eingerückt wird, wenn der Ausstellarm mit dem rahmenseitigen Widerlager außer Eingriff gelangt, während umgekehrt der Zusatzarm aus der flügelseitigen Sperrrast ausrückt, nachdem der Steuerarm in das rahmenseitige Widerlager um Eingriff gelangt ist. Es wird durch diese Zwangskopplung gewährleistet, daß die Parallelverschiebung des Flügels relativ zum feststehenden Rahmen erst eingeleitet werden kann, wenn der Flügel vollständig in seine Parallelabstellage gebracht worden ist. Auch kann der Flügel seine Parallelabstellage erst wieder verlassen, nachdem er in die für sein ordnungsgemäßes Schließen notwendige Relativstellung zum feststehenden Rahmen zurückgeschoben wurde.It is advantageous in this embodiment of an opening device that the opening arm forms a quadrilateral joint with the second lever arm of the control arm, the connecting bracket and the additional arm, via which the actuating movement of the control arm of the locking device and the additional arm of the opening device are brought into mutual dependence, namely in the Way that the additional arm on the wing is engaged in the locking catch when the extension arm comes out of engagement with the frame-side abutment, while conversely the additional arm disengages from the wing-side locking catch after the control arm has come into engagement in the frame-side abutment. This positive coupling ensures that the parallel displacement of the wing relative to the fixed frame can only be initiated when the wing has been brought completely into its parallel storage position. The sash can only leave its parallel storage position again after it has been pushed back into the relative position to the fixed frame necessary for its proper closing.

Es hat sich gezeigt, daß mit den Erfindungsmerkmalen die Ausstellarme durch die auslösbare Sperrvorrichtung bei der Bewegung des Flügels in Schiebe-Schließrichtung so lange sicher in ihrer Parallelabstellage fixiert sind, bis der Steueransatz des Steuerarms im Bereich der Schiebe-Schließendbewegung des Flügels mit dem Widerlager am feststehenden Rahmen in Wirkverbindung tritt und hieraus eine in bestimmter Weise gesteuerte Rückkoplungsbewegung für den Flügel verrastenden Zusatzarm abgeleitet wird. Bei in Schiebe-Schließrichtung wirkender Kraftausübung am Flügel wird die flügelseitige Rast für den Zusatzarm nämlich im Sperrsinne bzw. im Sinne einer formschlüssigen Verriegelung des Ausstellarms gegen den Flügel beansprucht.It has been shown that, with the features of the invention, the deployment arms are securely fixed in their parallel storage position by the releasable locking device during the movement of the wing in the sliding-closing direction until the control shoulder of the control arm in the area of the sliding-closing movement of the wing with the abutment on fixed frame comes into operative connection and from this a feedback movement controlled in a certain way for the wing latching additional arm is derived. When force is exerted on the wing in the sliding-closing direction, the wing-side latch for the additional arm is stressed in the blocking sense or in the sense of a positive locking of the extension arm against the wing.

Die Erfindung sieht nach Anspruch 2 vor, daß der Steuerarm am Laufwagen etwa in Fluchtlage der Anlenkstelle des Ausstellarms gelagert ist. Dabei können nach Anspruch 3 die beiden Hebelarme des Steuerarms stumpfwinklig zueinander angeordnet sein, wobei das Gelenk zwischen dessen zweitem Hebelarm und der Verbindungslasche bei Schließlage des Flügels mit dem Gelenk des Ausstellarms am Flügel auf einer zum feststehenden Rahmen etwa parallelen Ebene liegt.The invention provides according to claim 2 that the control arm is mounted on the carriage approximately in the aligned position of the articulation point of the extension arm. The two lever arms of the control arm can be arranged at an obtuse angle to one another, the joint between its second lever arm and the connecting plate when the wing is in the closed position with the joint of the extension arm on the wing on an approximately parallel plane to the fixed frame.

Bewährt hat sich nach Anspruch 4 eine Ausbildung, nach der der ortsfeste Anschlag am feststehenden Rahmen die Form einer bogenförmig gekrümmten Klaue hat, deren Aus- und Einlauföffnung der Ebene des feststehenden Rahmens näher liegt als ihr geschlossener Endabschnitt.A design has proven itself according to claim 4, according to which the fixed stop on the fixed frame has the shape of an arcuously curved claw, the outlet and inlet opening of which is closer to the plane of the fixed frame than its closed end section.

Die Funktionssicherheit der erfindungsgemäßen Ausstellvorrichtung läßt sich auch noch dadurch verbessern, daß nach Anspruch 5 der Steuerarm im Sperrsinne durch eine Vorspannkraft, insbesondere eine Feder, beaufschlagt ist.The functional reliability of the opening device according to the invention can also be improved in that, according to claim 5, the control arm is acted upon in the blocking direction by a prestressing force, in particular a spring.

Nach Anspruch 6 sieht die Erfindung vor, daß die Rastaufnahme gegen den Führungsschlitz geneigt verläuft und ihr Neigungswinkel wenigstens annähernd Deckungslage mit einem Krümmungsbogen hat, dessen Zentrum mit dem Gelenk des Zusatzarms an dem relativ zum Flügel in der Parallelabstelllage befindlichen Ausstellarm zusammenfällt. Dabei ist es nach Anspruch 7 besonders zweckmäßig, wenn die Rastaufnahme mit ihrem Ende vom feststehenden Rahmen weggerichtet am Flügel vorgesehen ist.According to claim 6, the invention provides that the locking receptacle is inclined against the guide slot and its angle of inclination has at least approximately cover position with an arc of curvature, the center of which coincides with the joint of the additional arm on the extension arm located relative to the wing in the parallel storage position. It is particularly expedient according to claim 7 when the latching receptacle is provided on the wing with its end facing away from the fixed frame.

Eine die Funktionssicherheit der Ausstellvorrichtung weiter verbessernde Maßnahme der Erfindung wird nach Anspruch 8 auch darin gesehen, daß die flügelseitigen Enden der Zusatzarme beider Ausstellvorrichtungen synchronbeweglich miteinander, z.B. über eine Schubstange, gekuppelt sind.A measure of the invention which further improves the functional reliability of the opening device is also seen according to claim 8 in that the wing-side ends of the additional arms of both opening devices can be moved synchronously with one another, e.g. are coupled via a push rod.

Eine besonders vorteilhafte Bauart einer erfindungsgemäßen Ausstellvorrichtung ist nach Anspruch 9 gekennzeichnet durch zwei mit ihrem Ausstellarm und ihrem Zusatzarm sowie dem zugehörigen flügelseitgen Lagerbock zueinander spiegelbildlich ausgebildete Laufwagen und durch ein Differential-Koppelgetriebe, über das die schwenkverschieblich am Flügel geführten Enden der Zusatzarme gegenläufig zwangsbeweglich miteinander verbindbar sind.A particularly advantageous design of an opening device according to the invention is characterized according to claim 9 by two with their extension arm and their additional arm and the associated wing-side bearing block mirror-image to each other and by a differential coupling gear via which the pivotally guided ends of the wing arms of the additional arms can be connected to each other in opposite directions so as to be positively movable are.

Eine solchermaßen ausgestaltete Ausstellvorrichtung kann in ein und derselben Ausführungsform sowohl für nach rechts als auch für nach links aus der Schließlage in Öffnungsrichtung horizontalverschiebbare Flügel von Fenstern und Türen benutzt werden, wobei die Ausstellvorrichtungen mit dem Flügel nach Art eines sogenannten Trapezlenkersystems zusammenarbeiten, das einer exakten Parallelverlagerung des Flügels quer zu seiner Ebene zuträglich ist.An opening device designed in this way can be used in one and the same embodiment both for leaves of windows and doors that can be horizontally displaced in the opening direction from the closed position to the right and to the left, the opening devices cooperating with the leaf in the manner of a so-called trapezoidal link system, which ensures exact parallel displacement of the wing is beneficial across its plane.

Das Differential-Koppelgetriebe kann nach Anspruch 10 in besonders vorteilhafter Weise aus zwei durch ein Umkehrgetriebe miteinander in ständiger Antriebsverbindung gehaltenen Schubstangen besteht. Der Gegenstand der Erfindung ist in der Zeichnung dargestellt. Es zeigen bzw. zeigt die

  • Fig. 1 und 2 in Stirnansicht und Seitenansicht eine parallelabstellbare Kippschiebetür bei Schließstellung des Flügels,

In den Fig. 1 bis 6 Zeichnung ist eine Balkon- bzw. Terrassentür dargestellt, die in einem feststehenden Rahmen 1 einen ortsfest. montierten Flügel 2 bzw. ein festes Türfeld 2 aufweist und die darüberhinaus mit einem beweglichen Flügel 3 ausgestattet ist.1 to 6 drawing, a balcony or terrace door is shown, which is fixed in a fixed frame 1. mounted wing 2 or a fixed door panel 2 and which is also equipped with a movable wing 3.

Der bewegliche Flügel 3 kann dabei relativ zum feststehenden Rahmen 1 und zum fest montierten Flügel bzw. Türfeld 2 aus der in den Fig. 1 und 2 angedeuteten Schließlage entweder in Kippöffnungsstellung gebracht werden, wie das die Fig. 3 und 4 erkennen lassen. Er läßt sich aber auch gegenüber dem feststehenden Rahmen 1 und dem ortsfest montierten Flügel bzw. festen Türfeld 2 in eine parallel abgestellte Lage bringen und dann aus dem Bereich der Durchgangsöffnung 4 des feststehenden Rahmens 1 in Horizontalrichtung vor den fest eingebauten Flügel bzw. das feste Türfeld 2 verschieben, wie das in den Fig. 5 und 6 zu sehen ist.The movable wing 3 can be brought relative to the fixed frame 1 and to the fixed wing or door panel 2 from the closed position indicated in FIGS. 1 and 2 either in the tilt-open position, as can be seen in FIGS. 3 and 4. However, it can also be placed in a parallel position relative to the fixed frame 1 and the fixed wing or fixed door panel 2 and then from the area of the passage opening 4 of the fixed frame 1 in the horizontal direction in front of the fixed wing or the fixed door panel 2 shift, as can be seen in FIGS. 5 and 6.

Um diese drei Stellungen des Flügels 3 relativ zum feststehenden Rahmen 1 sowie zum fest montierten Flügel bzw. zum festen Türfeld 2 zu ermöglichen wird zwischen dem Flügel 3 und dem feststehenden Rahmen 1 eine besondere Beschlaganordnung, nämlich ein sogenannter Kipp-Paralelabstell-Schiebebeschlag, vorgesehen, von der bzw. dem in den Fig. 1 bis 6 der Einfachheit halber nur die Bedienungshandhabe 5 am Flügel sowie die obere Ausstellvorrichtung 6 und die untere Ausstellvorrichtung 7 zwischen Flügel 3 und feststehendem Rahmen 1 zu sehen sind.In order to enable these three positions of the sash 3 relative to the fixed frame 1 and to the fixedly mounted sash or to the fixed door panel 2, a special fitting arrangement, namely a so-called tilt-parallel parking sliding fitting, is provided between the sash 3 and the fixed frame 1, 1 to 6, for the sake of simplicity, only the operating handle 5 on the sash and the upper opening device 6 and the lower opening device 7 between the sash 3 and the fixed frame 1 can be seen.

Von der Kinematik her können die obere Ausstellvorrichtung 6 und die untere Ausstellvorrichtung 7 ähnlich ausgelegt sein. Der Grundaufbau der oberen Ausstellvorrichtung 6 kann jedoch auch von solchen Bauarten abgeleitet sein, wie sie für Fenster oder Türen mit Kipp- oder Drehkippflügel zum Einsatz gelangen und beispielsweise durch das DE-GM 1 774 702, das DE-GM 1 813 918 sowie die DE-AS 10 75 007 zum Stand der Technik gehören. Es muß lediglich dafür gesorgt sein, daß die rahmenseitigen Anlenkstellen dieser Ausstellvorrichtungen in eine horizontale Schiebeführung 8 am oberen Querholm des feststehenden Rahmens 1 ständig eingreifen und eine synchrone Bewegung ihrer Ausstellarme gesichert ist.In terms of kinematics, the upper opening device 6 and the lower opening device 7 can be designed similarly. The basic structure of the upper opening device 6 can, however, also be derived from those types such as are used for windows or doors with tilt or turn-tilt sashes and, for example, through DE-GM 1 774 702, DE-GM 1 813 918 and DE -AS 10 75 007 belong to the prior art. It is only necessary to ensure that the frame-side articulation points of these opening devices constantly engage in a horizontal sliding guide 8 on the upper cross member of the fixed frame 1 and that a synchronous movement of their opening arms is ensured.

Die untere Ausstellvorrichtung 7 muß in jedem Falle so ausgelegt sein, daß sie das Gewicht des beweglichen Flügels 3 sicher trägt, während sie mit einer Laufschiene 9 am unteren Querholm des feststehenden Rahmens 1 zusammenwirkt.The lower opening device 7 must in any case be designed so that it bears the weight of the movable wing 3 securely while cooperating with a running rail 9 on the lower cross member of the fixed frame 1.

Im vorliegenden Falle kommt es hauptsächlich auf Ausbildung und Wirkungsweise der unteren Ausstellvorrichtung 7 an, die in den Fig. 7 und 8 in ihrem Grundaufbau und jeweils in der Draufsicht gezeigt ist. Diese Ausstellvorrichtung 7 weist dabei mindestens zwei baugleiche Ausstellarme 10 auf, von denen jeder über eine Achse 11 auf im wesentlichen horizontaler Ebene verschwenkbar an einem Laufwagen 12 angelenkt ist.In the present case, the main issue is the design and mode of operation of the lower opening device 7, which is shown in FIGS. 7 and 8 in its basic structure and in each case in a top view. This raising device 7 has at least two identical raising arms 10, each of which is articulated on a carriage 12 so as to be pivotable about an axis 11 on a substantially horizontal plane.

Jeder dieser Laufwagen 12 ist dabei mit zwei um im wesentlichen horizontale Achsen frei drehbar gelagerten Laufrollen 13 versehen, mittels denen er sich auf der Laufschiene 9 des feststehenden Rahmens 1 parallel zu dessen Ebene verfahrbar abstützt.Each of these carriages 12 is provided with two rollers 13 which are freely rotatable about substantially horizontal axes and by means of which it is supported on the running rail 9 of the fixed frame 1 so as to be movable parallel to its plane.

Die Ausstellarme 10 greifen mit ihrem anderen Ende über eine Achse 14 lediglich schwenkbar an der Unterkante des beweglichen Flügels 3 an.The extension arms 10 only pivotally engage the lower edge of the movable wing 3 via an axis 14.

Die beiden Laufwagen 12 der Ausstellvorrichtung 7 stehen vorzugsweise über eine Kupplungsstange 15 in fester Verbindung, so daß ihre Lagerachsen 11 für die beiden Ausstellarme 10 ständig in einem festen Abstand zuein ander gehalten sind. Auch die Achsen 14 der Ausstellarme 10 greifen mit konstantem Abstand zueinander an der Unterkante des Flügels 3 an, dergestalt, daß der Flügel 3, die Laufwagen 12 mit der Kupplungsstange 15 sowie die beiden Ausstellarme 14 miteinander ein Lenkerparallelogramm bilden. Mit Hilfe dieses Lenkerparallelogramms läßt sich der Flügel 3 quer zu seiner eigenen Ebene und auch quer zur Ebene des feststehenden Rahmens 1 zwischen der in Fig. 7 gezeigten Schließlage und der aus Fig. 8 ersichtlichen Parallelabstellage verstellen.The two carriages 12 of the opening device 7 are preferably in a fixed connection via a coupling rod 15, so that their bearing axes 11 for the two opening arms 10 are kept at a constant distance from one another. The axes 14 of the extension arms 10 engage at a constant distance from one another on the lower edge of the wing 3, in such a way that the wing 3, the carriage 12 with the coupling rod 15 and the two deployment arms 14 form a handlebar parallelogram with one another. With the help of this parallelogram of the handlebar, the wing 3 can be adjusted transversely to its own plane and also transversely to the plane of the fixed frame 1 between the closed position shown in FIG. 7 and the parallel storage position shown in FIG. 8.

Während bei der der Fig. 7 entsprechenden Einstellung der Ausstellvorrichtung 7 eine Bewegung des Flügels 3 aus der den Fig. 1 und 2 entsprechenden Schließage in die aus Fig. 3 und 4 ersichtliche Kippöffnungsstellung möglich ist, kann der Flügel 3 in der Parallelabstellage der Ausstellvorrichtung 7 nach Fig. 8 horizontal in die aus den Fig. 5 und 6 ersichtliche Öffnungsstellung geschoben werden.While in the setting of the opening device 7 corresponding to FIG. 7, a movement of the leaf 3 from the closing position corresponding to FIGS. 1 and 2 into the tilt opening position shown in FIGS. 3 and 4 is possible, the leaf 3 can be in the parallel parking position of the opening device 7 8 are pushed horizontally into the open position shown in FIGS. 5 and 6.

Damit der Flügel 3 relativ zum feststehenden Rahmen 1 während seiner Horizontalverschiebung ständig sicher in der Parallelabstellage gegenüber dem feststehenden Rahmen 1 verbleibt, ist es notwendig, die Parallelabstellage zumindest der Ausstellarme 10 der unteren Ausstellvorrichtung 7 gegenüber dem feststehenden Rahmen 1 bzw. den auf dessen Laufschiene 9 geführten Laufwagen 12 durch eine besondere Sperrvorrichtung 16 zu blockieren. Andererseits muß durch Aulösen der Sperrvorrichtung 16 die Blockierung der Parallelabstellage für die Ausstellarme 10 jedoch aufgehoben werden, sobald der Flügel 3 seine Schiebe-Schließendbewegung erreicht, damit er aus der Parallelabstellage nach Fig. 8 in die Schließlage nach Fig. 7 gegen den feststehenden Rahmen 1 angelegt werden kann.In order for the wing 3 to remain securely in the parallel storage position relative to the fixed frame 1 relative to the fixed frame 1 during its horizontal displacement, it is necessary that the parallel parking position of at least the extension arms 10 of the lower opening device 7 relative to the fixed frame 1 or on the running rail 9 thereof block guided carriage 12 by a special locking device 16. On the other hand, by releasing the locking device 16, the blocking of the parallel storage position for the extension arms 10 must, however, be released as soon as the sash 3 reaches its final sliding closing movement so that it moves from the parallel storage position according to FIG. 8 into the closed position according to FIG. 7 against the fixed frame 1 can be created.

Der Einfachheit halber wird eine Sperrvorrichtung 16 lediglich zwischen dem schließseitigen unteren Ausstellarm 10 und dem ihn tragenden Laufwagen 12 vorgesehen, obwohl es durchaus möglich ist, beiden Ausstellarmen 10 und Laufwagen 12 eine solche Sperrvorrichtung 16 zuzuordnen. Aufgrund des vorgesehenen Zusammenwirkens der beiden Ausstellarme 10 nach Art eines Lenkerparallelogramms reicht es jedoch völlig aus, die auslösbare Sperrvorrichtung 16 nur im Bereich des schließseitigen Ausstellarms 10 und des schließseitigen Laufwagens 12 vorzusehen.For the sake of simplicity, a locking device 16 is only provided between the closing lower lower arm 10 and the carriage 12 carrying it, although it is entirely possible to assign such a locking device 16 to both raising arms 10 and carriage 12. Due to the intended interaction of the two extension arms 10 in the manner of a handlebar parallelogram, it is entirely sufficient to provide the releasable locking device 16 only in the area of the closing-side raising arm 10 and the closing-side carriage 12.

Zumindest mit dem schließseitigen, unteren Ausstellarm 10 der Ausstellvorrichtung 7 steht, wie die Fig. 7 und 8 deutlich zeigen, ein Zusatzarm 17 mittels eines Gelenkes 18 an seinem einen Ende lediglich in schwenkbarer Dauerverbindung. Sein anderes Ende greift mit einem Zapfen 19 schwenkverschieblich in einen Führungsschlitz 20 ein, der sich in einem Lagerbock 21 befindet, welcher auf der raumseitigen Stirnfläche des Flügels 3 sitzt und auch den Träger für die Lagerachse 14 des Ausstellarms 10 bildet.At least with the lower, lower extension arm 10 of the opening device 7, as FIGS. 7 and 8 clearly show, an additional arm 17 is only in a pivotable permanent connection by means of a joint 18 at one end. Its other end engages with a pin 19 in a pivotable manner in a guide slot 20 which is located in a bearing block 21 which sits on the end face of the wing 3 on the room side and also the Carrier for the bearing axis 14 of the extension arm 10 forms.

Der Führungsschlitz 20 erstreckt sich im wesentlichen in Richtung der Ebene des Flügels 3 und ist an seinem der Parallelabstellage des Flügels 3 zugeordneten Ende mit einer Rastaufnahme 22 für den Zapfen 19 des Zusatzarmes 17 versehen. Diese Rastaufnahme 22 verläuft dabei gegenüber dem Führungsschlitz 20 geneigt, wobei ihr Neigungswinkel wenigstens annähernd Deckungslage mit einem Krümmungsbogen hat, dessen Zentrum mit dem Gelenk 18 des Zusatzarmes 17 am Ausstellarm 10 zusammenfällt, wenn dieser sich relativ zum Flügel 3 in der der Parallelabstellage entsprechenden Winkelstellung befindet, wie das die Fig. 8 erkennen läßt.The guide slot 20 extends essentially in the direction of the plane of the wing 3 and is provided at its end associated with the parallel storage position of the wing 3 with a latching receptacle 22 for the pin 19 of the additional arm 17. This snap-in receptacle 22 is inclined with respect to the guide slot 20, its angle of inclination at least approximately covering position with an arc of curvature, the center of which coincides with the joint 18 of the additional arm 17 on the extension arm 10 when the latter is in the angular position corresponding to the wing 3 in the parallel storage position , as can be seen in FIG. 8.

Die Rastaufnahme 22 schließt sich so an den Führungsschlitz 20 an, daß ihr Ende vom feststehenden Rahmen 2 weggerichtet am Flügel 3 vorgesehen ist.The locking receptacle 22 adjoins the guide slot 20 in such a way that its end facing away from the fixed frame 2 is provided on the wing 3.

Während sich der Zapfen 19 des Zusatzarms 17 im Führungsschlitz 20 längsverschiebt, wenn der Ausstellarm 10 gegenüber dem Flügel 3 um die Gelenkachse 14 am Lagerbock 21 zwischen der Ausgangslage nach Fig. 7 und der Parallelabstellage nach Fig. 8 verschwenkt wird, kann er in der Parallel abstellage nach Fig. 8 um das Gelenk 18 hinein oder aber aus dieser in entgegengesetzter Richtung herausgeschwenkt werden.While the pin 19 of the additional arm 17 shifts longitudinally in the guide slot 20 when the extension arm 10 is pivoted relative to the wing 3 about the hinge axis 14 on the bearing block 21 between the starting position according to FIG. 7 and the parallel parking position according to FIG. 8, it can be parallel 8 around the hinge 18 or swung out of this in the opposite direction.

Bei Eingriff des am Zusatzarm 17 befindlichen Zapfens in die Rastaufnahme 22 wirkt der Zusatzarm 17 mit dem Ausstellarm 10 als Sperrvorrichtung 16 zusammen, die den Ausstellarm 10 relativ zum Flügel 3 in seiner der Parallelabstellage entsprechenden Winkelstellung blockiert. Der Flügel 3 wird hierdurch gegenüber dem feststehenden Rahmen 1 in der vorgegebenen, parallelen Abstandslage gehalten, in welcher er mittels der Laufwagen 12 parallel zur Ebene des feststehenden Rahmens 1 in Horizontalrichtung verschoben werden kann.When the pin located on the additional arm 17 engages in the latching receptacle 22, the additional arm 17 interacts with the extension arm 10 as a locking device 16 which blocks the extension arm 10 relative to the wing 3 in its angular position corresponding to the parallel storage position. The wing 3 is thereby held relative to the fixed frame 1 in the predetermined, parallel spacing position in which it can be moved in the horizontal direction by means of the carriage 12 parallel to the plane of the fixed frame 1.

Die vom Zusatzarm 17 und der Rastaufnahme 22 gebildete Sperrvorrichtung 16 für den Ausstellarm 10 wird durch einen Steuerarm 23 beeinflußt, welcher am Laufwagen 12, etwa auf einer horizontalen Ebene, begrenzt schwenkbeweglich gelagert ist. Die Lagerachse für den Steuerarm 23 kann dabei in vorteilhafter Weise Fluchtlage mit der Achse 11 aufweisen, um die der Ausstellarm 10 schwenkbeweglich mit dem Laufwagen 12 in Verbindung steht.The locking device 16 formed by the additional arm 17 and the latching receptacle 22 for the extension arm 10 is influenced by a control arm 23 which is mounted on the carriage 12, for example on a horizontal plane, so that it can be pivoted to a limited extent. The bearing axis for the control arm 23 can advantageously be in alignment with the axis 11, about which the extension arm 10 is pivotally connected to the carriage 12.

Der Steuerarm 23 ist als zweiarmiger Hebel ausgebildet, dessen einer Hebelarm 24 in Schiebe-Schließrichtung über den Laufwagen 12 hinausragt und an seinem freien Ende einen Zapfen als Riegelglied 25 trägt. Der andere Hebelarm 26 des Steuerarms 23 verläuft unter einem stumpfen Winkel zu dessen Helebarm 24 und greift mit seinem freien Ende über ein Gelenk 27 an einer Verbindungslasche 28 an, die wiederum über ein Gelenk 29 mit dem Zusatzarm 17 in ständiger Verbindung steht, welches zwischen dessen Gelenk 18 am Ausstellarm 10 und dem Zapfen 19 gelegen ist. In der Schließlage des Flügels 3 (Fig. 7) liegt das Gelenk 27 mit dem Gelenk 14 des Ausstellarms 10 auf einer zum feststehenden Rahmen 1 parallelen Ebene.The control arm 23 is designed as a two-armed lever, one lever arm 24 of which projects beyond the carriage 12 in the sliding-closing direction and carries a pin as a locking member 25 at its free end. The other lever arm 26 of the control arm 23 extends at an obtuse angle to its helebarm 24 and engages with its free end via a joint 27 on a connecting bracket 28, which in turn is in constant connection via a joint 29 with the additional arm 17, which is between the latter Joint 18 on the extension arm 10 and the pin 19 is located. In the closed position of the wing 3 (FIG. 7), the joint 27 with the joint 14 of the extension arm 10 lies on a plane parallel to the fixed frame 1.

Der Ausstellarm 10 bildet mit dem Hebelarm 26 des Steuerarms 23, der Verbindungslasche 28 und dem Zusatzarm 17 ein Gelenkviereck. Über dieses Gelenkviereck kann dabei der Zapfen 19 des Zusatzarms 17 bei Parallelabstelllage des Flügels 3 (Fig. 8) im Bereich der Rastaufnahme 22 in Abhängigkeit von einer durch das Riegelglied 25 hervorgerufenen Schwenkbewegung des Steuerarms 23 zwischen der strichpunktiert eingezeichneten Sperrlage und der durch voll ausgezogene Linien angedeuteten Freigabstellung begrenzt winkelverstellt werden.The extension arm 10 forms with the lever arm 26 of the control arm 23, the connecting bracket 28 and the additional arm 17 a four-bar linkage. The pin 19 of the additional arm 17 can be positioned over this joint quadrilateral when the wing 3 is in the parallel storage position (FIG. 8) in the region of the latching receptacle 22 as a function of a pivoting movement of the control arm 23 caused by the locking member 25 between the broken-line position shown in broken lines and the solid lines indicated release position can be adjusted angle limited.

Zur Betätigung des Steuerarms 23 wirkt der am freien Ende seines Hebelarms 24 als Riegelglied 25 vorgesehene Zapfen mit einem am feststehenden Rahmen 1 ortsfest angebrachten Widerlager 30 zusammen, das die Form einer bogenförmig gekrümmten Klaue 31 hat, deren Aus- und Einlauföffnung 32 der Ebene des feststehenden Rahmens 1 näher liegt als ihr geschlossener Endabschnitt 33.To actuate the control arm 23, the pin provided on the free end of its lever arm 24 as a locking member 25 interacts with an abutment 30 which is fixedly attached to the fixed frame 1 and which has the shape of an arcuately curved claw 31, the outlet and inlet opening 32 of which is at the level of the fixed one Frame 1 is closer than its closed end portion 33.

Wird der Flügel 3 durch Horizontalverschiebung im Schließsinne - nach den Fig. 7 und 8 von rechts nach links - verschoben, dann läuft das Riegelglied 25 von rechts nach links in die Aus- und Einlauföffnung 32 der Klaue 31 ein und wird von dieser in Richtung vom feststehenden Rahmen 1 weg abgelenkt, bis es in den Bereich des geschlossenen Endabschnitts 33 gelangt. Hierdurch wird der Steuerarm 23 gegenüber dem Laufwagen 12 um die Achse 11 verschwenkt, und zwar so, daß sich sein Hebelarm 24 vom feststehenden Rahmen 1 weg, sein Hebelarm 26 aber auf den feststehenden Rahmen 1 zu verschwenkt. Der Hebelarm 26 übt damit eine Zugkraft an der Verbindungslasche 28 aus, welche auf den Zusatzarm 17 übertragen wird. Der hieran befindliche Zapfen 19 wird damit aus der Rastaufnahme 22 in den Bereich des Führungsschlitzes 20 zurückgezogen, so daß die Sperrvorrichtung 16 unwirksam ist. Nunmehr kann der Ausstellarm 10 aus der Parallelabstellage nach Fig. 8 in Richtung gegen den feststehenden Rahmen 1 geschwenkt werden, bis der Flügel 3 hierzu die Schließlage nach Fig. 7 einnimmt.If the wing 3 is displaced horizontally in the closing direction - according to FIGS. 7 and 8 from right to left - then the locking member 25 runs from right to left into the outlet and inlet opening 32 of the claw 31 and is moved by this in the direction of fixed frame 1 deflected away until it reaches the area of the closed end portion 33. As a result, the control arm 23 is pivoted relative to the carriage 12 about the axis 11, in such a way that its lever arm 24 moves away from the fixed frame 1, but its lever arm 26 pivots towards the fixed frame 1. The lever arm 26 thus exerts a tensile force on the connecting bracket 28, which is transmitted to the additional arm 17. The pin 19 located thereon is thus withdrawn from the latching receptacle 22 into the region of the guide slot 20, so that the locking device 16 is ineffective. The extension arm 10 can now be pivoted from the parallel storage position according to FIG. 8 towards the fixed frame 1 until the wing 3 assumes the closed position according to FIG. 7 for this purpose.

Durch das Einschwenken des Ausstellarms 10 wird über das von diesem, dem Hebelarm 16, der Verbindungslasche 28 und dem Zusatzarm 17 gebil dete Gelenkviereck der Zapfen 19 des Zusatzarms 17 in Längsrichtung des Führungsschlitzes 20 verlagert, und zwar in solcher Art und Weise, daß gleichzeitig über den Steuerarm 23 das Riegelglied 25 mit der Klaue 31 am feststehenden Rahmen 1 in Formschlußeingriff gehalten und damit unbeweglich Lagenfixiert wird.By pivoting the Ausstellarms 10 is about this, the lever arm 16, the connecting plate 28 and the additional arm 17 gebil Dete quadrilateral pin 19 of the additional arm 17 in the longitudinal direction of the guide slot 20, in such a way that at the same time that the control arm 23, the locking member 25 with the claw 31 on the fixed frame 1 in positive engagement and thus immobile positions is fixed.

Erst wenn der Flügel 3 relativ zum feststehenden Rahmen 1 mittels der Ausstellarme 10 aus der Schließlage nach Fig. 7 in die Parallelabstellage nach Fig. 8 gebracht ist, gibt das Gelenkviereck den Steuerarm 23 und damit dessen Riegelglied 25 für eine mögliche, begrenzte Schwenkbewegung um die Achse 11 frei. Erst daraufhin ist dann eine Horizontalverschiebung des Flügels 3 relativ zum feststehenden Rahmen 1 von links nach rechts möglich, weil das Riegelglied 25 in der bogenformig gekrümmten Klaue 31 von deren geschlossenem Endabschnitt 33 in Richtung zur Aus- und Einlauföffnung 32 hin wandern kann. Mit dieser Wanderbewegung des Riegelgliedes 25 innerhalb der bogenförmig gekrümmten Klaue 31 geht jedoch das zwangsweise Einschwenken das Zapfens 19 am Zusatzarm 17 in die Rastaufnahme 22 einher, wodurch die Sperrvorrichtung 16 zwangsläufig in Tätigkeit tritt.Only when the sash 3 is brought relative to the fixed frame 1 by means of the extension arms 10 from the closed position according to FIG. 7 into the parallel storage position according to FIG. 8, does the four-bar linkage give the control arm 23 and thus its locking member 25 for a possible, limited pivoting movement about the Axis 11 free. Only then is it possible to move the wing 3 horizontally relative to the fixed frame 1 from left to right, because the locking member 25 can move in the curved claw 31 from its closed end section 33 in the direction of the outlet and inlet opening 32. With this movement of the locking member 25 within the arc claw 31 curved in shape, however, the forcible pivoting of the pin 19 on the additional arm 17 into the latching receptacle goes hand in hand, whereby the locking device 16 inevitably comes into operation.

Bewährt hat es sich, den Steuerarm 23 und/oder das Verbindungsgelenk 27 zwischen dessen Hebelarm 26 und der Verbindungslasche 28 durch eine Vorspannkraft, insbesondere eine - nicht gezeigte - Schenkelfeder, so zu beaufschlagen, daß hierdurch der Zusatzarm 17 ständig im Sinne eines Einrückens seines Zapfens 19 in die Rastaufnahme 22 beaufschlagt ist. Auch wenn das Riegelglied 25 sich außerhalb des Wirkbereichs des ortsfesten Widerlagers 30 bzw. der Klaue 32 befindet, wird hierdurch die Sperrvorrichtung 16 selbsttätig in ihrer Eingriffslage gehalten und fixiert.It has proven useful to act on the control arm 23 and / or the connecting joint 27 between its lever arm 26 and the connecting bracket 28 by means of a pretensioning force, in particular a leg spring (not shown), such that the additional arm 17 is thereby constantly in the sense of engaging its pin 19 is loaded into the latching receptacle 22. Even if the locking member 25 is outside the effective range of the fixed abutment 30 or the claw 32, the locking device 16 is thereby automatically held and fixed in its engaged position.

Aus den Fig. 7 und 8 der Zeichnung ist noch ersichtlich, daß beide Ausstellarme 10 der Ausstellvorrichtung 7 mit einem Zusatzarm 17 versehen werden können. Auch der zweite Zusatzarm 17 wirkt dabei über seinen Zapfen 19 mit einem Führungsschlitz 20 und einer Rastaufnahme 22 am Flügel 3 zusammen.7 and 8 of the drawing it can still be seen that both raising arms 10 of the raising device 7 can be provided with an additional arm 17. The second additional arm 17 also interacts via its pin 19 with a guide slot 20 and a latching receptacle 22 on the wing 3.

In diesem Falle ist es besonders zu empfehlen, die flügelseitigen Enden der beiden Zusatzarme 17 synchronbeweglich miteinander zu kuppeln, und zwar beispielsweise über eine Schubstange 34, die an den Zapfen 19 angreift.In this case, it is particularly recommended that the wing-side ends of the two additional arms 17 be coupled to one another in a synchronously movable manner, for example via a push rod 34 which engages the pin 19.

Abgesehen davon, daß hierdurch Gleichlaufbewegungen der beiden Ausstellarme 10 der Ausstellvorrichtung 7 zwangsgesteuert werden, wirken auch beide Zusatzarme 17 als Sperrvorrichtung 16 mit dem Flügel 3 zusammen, die beide von einem gemeinsamen Steuerarm 23 her betätigt werden.In addition to the fact that this controls the synchronous movements of the two raising arms 10 of the raising device 7, both additional arms 17 also act as a blocking device 16 with the wing 3, both of which are actuated by a common control arm 23.

Die Ausstellvorrichtung 7 nach den Fig. 9 und 10 unterscheidet sich von derjenigen nach den Fig. 7 und 8 im wesentlichen dadurch, daß sie aus zwei jeweils mit ihrem Ausstellarm 10 und ihrem Zusatzarm 17 sowie dem zugehörigen flügelseitigen Lagerbock 21 zueinander spiegelbildlich ausgebildeten Laufwagen 12 besteht. Jeder dieser Laufwagen 12 ist dabei auch mit einem Steuerarm 23 und einer diesen mit dem Zusatzarm 17 koppelnden Verbindungslasche 28 ausgestattet.The opening device 7 according to FIGS. 9 and 10 differs from that according to FIGS. 7 and 8 essentially in that it consists of two carriages 12 which are each mirror images of one another with their opening arm 10 and their additional arm 17 and the associated wing-side bearing bracket 21 . Each of these carriages 12 is also equipped with a control arm 23 and a connecting link 28 coupling it to the additional arm 17.

In diesem Falle stehen die über die Zapfen 19 im Führungsschlitz 20 schwenkverschieblich am Flügel 3 geführten Enden beider Zusatzarme 17 gegenläufig zwangsbeweglich durch ein Differential-Koppelgetriebe 35 miteinander in Verbindung, welches beispielsweise zwei Schubstangen 36a und 36b aufweist, die durch ein Umkehrritzel 37 miteinander in ständiger Antriebsverbindung gehalten sind.In this case, the ends of both additional arms 17, which are pivotably displaceably guided on the wing 3 via the pins 19 in the guide slot 20, are connected in opposite directions by a differential coupling gear 35 which, for example, has two push rods 36a and 36b, which are in constant contact with one another by means of a reversing pinion 37 Drive connection are held.

Die in den Fig. 9 und 10 dargestellte Ausstellvorrichtung 7 hat gegenüber derjenigen nach den Fig. 7 und 8 den Vorteil, daß sie sich in ein und derselben Ausführungsform sowohl für horizontal nach rechts als auch für horizontal nach links in Öffnungsstellung verschiebbare Fenster- und Türflügel 3 in Benutzung nehmen läßt. Vorteilhaft ist darüberhinaus aber auch, daß die Ausstellvorrichtung 7 nach den Fig. 9 und 10 zwischen dem Flügel 3 und den beiden Laufwagen 12 nach Art eines Trapezlenkersystems wirksam ist, bei dem die flügelseitigen Lagerachsen 14 beide Ausstellarme 10 übereinstimmenden Stützabstand von den beiden Flügelecken aufweisen.The opening device 7 shown in FIGS. 9 and 10 has the advantage over that according to FIGS. 7 and 8 that in one and the same embodiment they can be moved both horizontally to the right and horizontally to the left in the open position of the window and door leaves 3 can be used. It is also advantageous, however, that the raising device 7 according to FIGS. 9 and 10 is effective between the wing 3 and the two carriages 12 in the manner of a trapezoidal link system, in which the wing-side bearing axles 14 have both raising arms 10 corresponding support distance from the two wing corners.
