Description

Die Erfindung betrifft einen Kettenantrieb für ausstellbare Flügel von Fenstern, Türen oder dgl. mit den Merkmalen des Oberbegriffs des Anspruchs 1 (vgl. FR-A-2 278 891) bzw. gem. Oberbegriff des Anspruchs 7.The invention relates to a chain drive for extendable Wing of windows, doors or the like. With the characteristics of Preamble of claim 1 (cf. FR-A-2 278 891) or according to Preamble of claim 7.

Die FR-A-2 278 891 (Teleflex) zeigt einen Kettenantrieb für ausstellbare Flügel, in welchem eine Kettenführung drei zur Längsseite des Gehäuses parallele Kettenführungsabschnitte aufweist. An der einen Stirnseite des Gehäuses befindet sich ein Kettenantriebsrad, das mit der Ausstellkette im Eingriff ist und die Kette in das Gehäuse einfahren oder aus diesem herausfahren kann. Die Achse des Kettenantriebsrades ist senkrecht zur Flachseite des Gehäuses. Neben dem Kettenantriebsrad wird die eingeführte Kette mit drei zueinander im wesentlichen parallelen Kettenführungsabschnitten gelagert, wozu zwei enge Krümmungsradien erforderlich sind. Damit erreicht dieser Kettenantrieb im Stand der Technik eine besonders große Kettenlänge bei vernünftigem Ausmaß des Gehäuses, so daß ein großer Öffnungswinkel und eine besonders große freizugebende Belüftungsöffnung für den ausstellbaren Flügel erreicht wird. FR-A-2 278 891 (Teleflex) shows a chain drive for hinged wings, in which a chain guide has three chain guide sections parallel to the long side of the housing. On one end of the housing there is a chain drive wheel, which is in engagement with the release chain and can drive the chain into or out of the housing. The axis of the chain drive wheel is perpendicular to the flat side of the housing. In addition to the chain drive wheel, the inserted chain is supported with three chain guide sections which are essentially parallel to one another, for which purpose two narrow radii of curvature are required. This chain drive in the prior art thus achieves a particularly large chain length with a reasonable size of the housing, so that a large opening angle and a particularly large ventilation opening to be opened for the deployable wing is achieved.

Demgegenüber ist es Aufgabe der Erfindung, eine weitere Verlängerung der in dem Gehäuse einbringbaren Kette zu ermöglichen und dies bei in etwa gleichen Gehäuseabmessungen und zusätzlich in dem Gehäuse angeordnetem Antrieb. Diese Aufgabe wird mit Anspruch 1 oder Anspruch 7 gelöst.In contrast, it is an object of the invention to enable a further extension of the chain which can be introduced into the housing, and this with approximately the same housing dimensions and additionally with a drive arranged in the housing. This object is solved with claim 1 or claim 7.

In dem Kettenantriebs-Gehäuse von begrenzten Abmessungen wird so eine große Länge der für die Aufnahme der Ausstellkette erforderlichen Kettenführung untergebracht und diese große Kettenlänge auch sicher mit dem motorischen Antrieb ausgefahren bzw. eingezogen, weil sich die drei Kettenabschnitte über im wesentlichen gleiche, der Länge des Gehäuses entsprechende, Längen erstrecken. Gleichzeitig wird die Antriebsachse des motorischen Antriebes parallel zu den erwähnten drei Kettenführungsabschnitten ausgerichtet. Die Einbauhöhe des Antriebsmotors entspricht in etwa der Höhe des Gehäuses. So kann eine kompakte Anordnung von Ketten-Führungsabschnitten und elektromotorischem Antrieb erreicht werden, bei nahezu vollständiger Ausnutzung des in dem Gehäuse zur Verfügung stehenden Raumes, ohne daß die in das Gehäuse eingeführte Kette enge Krümmungsradien durchlaufen muß.So in the chain drive housing of limited dimensions a large length of the chain to accommodate the display chain required chain guide and this large Chain length also extended safely with the motor drive or moved in, because the three chain sections over in essentially the same, corresponding to the length of the housing, Extend lengths. At the same time, the drive axis of the motor drive parallel to the three mentioned Chain guide sections aligned. The installation height of the Drive motor corresponds approximately to the height of the housing. So can a compact arrangement of chain guide sections and electric motor drive can be achieved at almost full utilization of the available in the housing standing space without the chain inserted into the housing must pass through narrow radii of curvature.

Bevorzugt kann eine wendelförmige Anordnung der Kettenführung eingesetzt werden (Anspruch 3). Dabei läßt sich eine besonders günstige räumliche und auch für den Betrieb vorteilhafte Anordnung der gesamten Kettenlänge in dem Kettenantriebsgehäuse erreichen (Anspruch 6).A helical arrangement of the chain guide can be preferred are used (claim 3). One can be special favorable spatial and also advantageous for the operation Arrangement of the entire chain length in the chain drive housing achieve (claim 6).

Zwar ist in der AU-A 26 009/77 (Ogden) bereits eine wendelförmige Anordnung mit zwei oder mehr Etagen für die eingeführte Kette vorgesehen, wobei eine Rampe (dort Figur 14) verwendet wird. In diesem Beispiel aus der Stand der Technik wird das Kettenantriebsritzel seitlich neben den (dort nur zwei) Führungsabschnitten angeordnet, so daß sich enge Krümmungsradien ergeben bei gleichzeitig langgestrecktem Gehäuse, ohne daß der elektromotorische Antrieb bei dieser Anordnung Berücksichtigung findet. Ein elektromotorischer Antrieb wird auch in Verbindung mit einer Ausführungsform gemäß US-A 4,481,735 (Jentoft) vorgeschlagen, bei der allerdings die in das Gehäuse eingeführte Kette über zwei Endlagenschalter abgetastet wird und keine drei zueinander parallele Kettenführungsabschnitte im Gehäuse erreicht werden, sondern nur 1½ zueinander parallele Abschnitte vorgesehen sind (dort Figur 10). Außerhalb des Gehäuses wird der Motor (dort 44) angeordnet, der mit der senkrecht zu den Führungsabschnitten angeordneten Achse des Antriebsritzels in mechanischer Verbindung steht. Eine kompakte Anordnung einer langen Ausstellkette kann dort nicht erreicht werden.In AU-A 26 009/77 (Ogden) a helical arrangement with two or more levels is already provided for the inserted chain, a ramp (there, FIG. 14) being used. In this example from the prior art, the chain drive pinion is arranged laterally next to the (only two) guide sections, so that there are narrow radii of curvature with an elongated housing at the same time, without the electromotive drive being taken into account in this arrangement. An electric motor drive is also proposed in connection with an embodiment according to US-A 4,481,735 (Jentoft), in which, however, the chain inserted into the housing is scanned via two limit switches and no three parallel chain guide sections are reached in the housing, but only 1½ parallel to each other Sections are provided (there Figure 10). The motor (there 44) is arranged outside the housing and is in mechanical connection with the axis of the drive pinion arranged perpendicular to the guide sections. A compact arrangement of a long display chain cannot be achieved there.

Die Erfindung wird nachfolgend anhand mehrerer Ausführungsbeispiele näher erläutert.

The invention is explained below with reference to several examples of execution in detail.
Figure 1-3
is a tilting window equipped with a chain drive in front view or in vertical section in the closed position and the maximum open position.
Figure 4
is a top view and in cross section of a first embodiment of the chain drive.
Figures 6-8
is a modified, preferred embodiment in plan view, in cross section and in longitudinal section.

Die Figuren 1-3 zeigen ein Kippfenster mit besonders großem Öffnungswinkel. Das Fenster besteht üblicherweise aus einem Blendrahmen, an dem durch untere Kipplager 3 ein Flügelrahmen angelenkt ist, an dessen oberen Ende über einen Befestigungsbock 6 das freie Ende einer Ausstellkette 7 befestigt ist, die zu einem Kettenantrieb 4 gehört, der ein die Antriebselemente und die Kettenführung aufnehmendes Gehäuse 5 umfaßt, das oberhalb des Flügelüberschlages am Blendrahmen befestigt ist. Figures 1-3 show a tilt window with a particularly large opening angle. The window usually consists of a frame on which a sash frame is articulated by lower tilting bearings 3, at the upper end of which the free end of an opening chain 7 is attached via a mounting bracket 6, which chain chain belongs to a chain drive 4, which includes the drive elements and the chain guide accommodating housing 5, which is attached above the wing flap on the frame.

Das Gehäuse 5 besteht zur leichteren Montage aus wenigstens zwei Gehäuseteilen, die fest miteinander verbunden sind.The housing 5 consists of at least two for easier assembly Housing parts that are firmly connected.

Wie aus Figur 4 und 5 ersichtlich ist, kann das Gehäuse 10 im inneren Bereich Montageelemente 15, 16 zur Anbringung eines Motors mit Getriebe und Getriebeausgangsritzel und zur Montage eines Kettenantriebsrades aufweisen, wobei die Motor-Getriebeachse mit 16a und die Drehachse des Kettenantriebs-Gliedes mit 15a bezeichnet sind. In dem Gehäuse, das als langgestrecktes Flachgehäuse ausgebildet ist, dessen Länge mit L in Figur 4 angegeben ist, ist eine Kettenführung angeordnet. Diese besteht im wesentlichen aus drei parallel zur Längsrichtung des Gehäuses und zueinander angeordneten Kettenführungsabschnitten 12a, 12b, 12c, deren Länge etwa der Länge L des Gehäuses entsprechen. Diese Längenabschnitte sind durch Übergangsabschnitte miteinander verbunden, von denen sich zwei Abschnitte 13 und 14 parallel zu den Stirnseiten des Gehäuses erstrecken. Der Abschnitt 14 bildet zugleich den Austrittsabschnitt der Kettenführung, deren Austrittsöffnung 14a ist.As can be seen from FIGS. 4 and 5 , the housing 10 can have mounting elements 15, 16 in the inner region for attaching a motor with a transmission and transmission output pinion and for mounting a chain drive wheel, the motor transmission axis with 16a and the axis of rotation of the chain drive link with 15a. A chain guide is arranged in the housing, which is designed as an elongated flat housing, the length of which is indicated by L in FIG . This essentially consists of three chain guide sections 12a, 12b, 12c arranged parallel to the longitudinal direction of the housing and to one another, the length of which corresponds approximately to the length L of the housing. These length sections are connected to one another by transition sections, of which two sections 13 and 14 extend parallel to the end faces of the housing. The section 14 also forms the exit section of the chain guide, the exit opening of which is 14a.

Der Kettenantrieb in beiden Bewegungsrichtungen erfolgt im Übergangsbereich zwischen dem Austrittsabschnitt 14 und dem anschließenden Längsabschnitt 12a der Kettenführung. Alle Führungsabschnitte liegen in einer gemeinsamen, zur Oberseite des Gehäuses 10 parallelen Ebene, wie dies Figur 5 veranschaulicht, welche einen Schnitt entlang der Schnittlinie V-V der Figur 4 darstellt.The chain drive in both directions of movement takes place in the transition region between the outlet section 14 and the subsequent longitudinal section 12a of the chain guide. All guide sections lie in a common plane parallel to the upper side of the housing 10, as illustrated in FIG. 5 , which represents a section along the section line VV in FIG .

Die Höhe des Gehäuses 10 wird durch die Einbauhöhe des eigentlichen Antriebs bestimmt, während die Breitenabmessungen des Gehäuses durch die in gleicher Ebene nebeneinanderliegenden Längsabschnitte 12a-12c der Kettenführung bestimmt werden.The height of the housing 10 is determined by the installation height of the actual drive determines while the width dimensions of the housing by the side by side in the same plane Longitudinal sections 12a-12c of the chain guide can be determined.

Bei der Ausführungsform nach Figur 6-8 läßt sich das Verhältnis zwischen Gesamtlänge der Ausstellkette und Größenabmessungen des Kettenantriebsgehäuses noch wesentlich günstiger gestalten. Das Gehäuse 20, 21 des Kettenantriebes ist wiederum mehrteilig ausgebildet und weist eine flache, langgestreckte Kastenform auf. Der mittlere Bereich des Gehäuses ist der Höhe nach und der Breite nach für die Unterbringung des eigentlichen Antriebes vorgesehen. Dieser besteht aus einem Antriebsmotor 22 mit Getriebe 23 und Ausgangswelle 24, auf der beispielsweise ein Schraubenrad oder eine Schnecke 25 angeordnet ist, welche in Antriebseingriff mit einem Zahnrad 27 steht, das gleichachsig und antriebsmäßig mit einem Kettenantriebsrad 29 verbunden ist. Die Drehachse des eigentlichen Antriebes ist mit 26 und die Drehachse des Zahnrades 27 und des Kettenrades 29 mit 28 bezeichnet. Wie aus Figur 7 ersichtlich ist, liegt die Drehachse 26 in einer zur Flachseite des Gehäuses parallelen Ebene 35, welche die Gehäusehöhe etwa halbiert. In etwa gleichen Abständen oberhalb und unterhalb der Ebene 35 liegen in Ebenen 36 und 37 schleifenförmige Abschnitte der durchgehenden Kettenführung 32. Die beiden Ebenen sind durch einen schrägen Rampenabschnitt 39 der Kettenführung miteinander verbunden. Bei dieser Ausbildung bildet die Kettenführung in einer den Austritt 33 aus dem Gehäuse aufweisenden Ebene einschließlich des rampenförmigen Abschnittes 39 eine volle Schleife, die sich entlang der Innenkonturen des Gehäuses erstreckt und deutlich mehr als das zweifache der Länge des Gehäuses 20, 21 aufweist. Zusätzlich erstreckt sich die Kettenführung in der anderen Ebene nochmals etwa über eine Länge entsprechend der halben Länge einer vollen Schleife der beschriebenen Art. Man erhält so eine besonders große Länge der Ausstellkette bei vergleichsweise geringen Abmessungen des Gehäuses. Auch hier erfolgt der Antrieb der Ausstellkette unmittelbar am Übergangsabschnitt mit dem die Austrittsöffnung 33 aufweisenden Kettenführungsabschnitt und dem anschließenden ersten sich entlang der Länge des Gehäuses erstreckenden Führungsabschnitt. Die Kette 30 ist zuverlässig in der Kettenführung aufgenommen und geführt. Der wesentliche Teil der Höhe des Gehäuses wird durch die notwendige Einbauhöhe des Motors 22 weitgehend bestimmt. Das gleiche gilt für die Breite und für die Länge des Gehäuses.In the embodiment according to FIGS. 6-8 , the ratio between the total length of the chain and the size dimensions of the chain drive housing can be made even more favorable. The housing 20, 21 of the chain drive is again made of several parts and has a flat, elongated box shape. The height and width of the central area of the housing are intended to accommodate the actual drive. This consists of a drive motor 22 with gear 23 and output shaft 24, on which, for example, a helical gear or a worm 25 is arranged, which is in drive engagement with a gear 27 which is connected coaxially and in terms of drive with a chain drive gear 29. The axis of rotation of the actual drive is designated by 26 and the axis of rotation of the gear 27 and the sprocket 29 by 28. As can be seen from FIG. 7 , the axis of rotation 26 lies in a plane 35 which is parallel to the flat side of the housing and which roughly halves the housing height. At approximately equal intervals above and below level 35, loop-shaped sections of the continuous chain guide 32 lie in levels 36 and 37. The two levels are connected to one another by an inclined ramp section 39 of the chain guide. In this embodiment, the chain guide forms a full loop in a plane having the exit 33 from the housing, including the ramp-shaped section 39, which extends along the inner contours of the housing and has significantly more than twice the length of the housing 20, 21. In addition, the chain guide extends in the other plane again over a length corresponding to half the length of a full loop of the type described. In this way, a particularly long length of the chain is obtained with comparatively small dimensions of the housing. Here, too, the drive-out chain is driven directly at the transition section with the chain guide section having the outlet opening 33 and the subsequent first guide section extending along the length of the housing. The chain 30 is reliably received and guided in the chain guide. The essential part of the height of the housing is largely determined by the necessary installation height of the motor 22. The same applies to the width and length of the housing.
