Description

Kettenantrieb mit innenliegende AntriebsmotorChain drive with internal drive motor
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) .The invention relates to a chain drive for hinged sashes of windows, doors or the like. With the features of the preamble of claim 1 (see. FR-A-2 278 891).
In zunehmenden Maße werden für Kipp- oder Klappfenster motorisch angetriebene Ausstelleinrichtungen, wie Ausstellscheren oder dgl. verwendet. Der mögliche Ausstellwinkel und damit die freizugebende Öffnung ist bei Ausstellscheren begrenzt. Es ist aber in vielen Fällen gefordert, daß eine große Öffnung des Flügels ermöglicht wird, um zum Beispiel im Gefahrenfalle für einen raschen und zuverlässigen Rauchabzug oder dgl. Sorge zu tragen. Für diese Fälle sind in der Regel Ausstellscheren nicht geeignet.Motorized opening devices, such as opening scissors or the like, are increasingly being used for tilting or hinged windows. The possible opening angle and thus the opening to be opened is limited for opening scissors. In many cases, however, it is required that a large opening of the wing be made possible, for example to ensure rapid and reliable smoke extraction or the like in the event of danger. Knife scissors are generally not suitable for these cases.
Die FR-A-2 278 891 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 einFR-A-2 278 891 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. There is a on one end of the housing
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.Chain drive wheel, which is in engagement with the release chain and can insert 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 long chain length with a reasonable size of the housing, so that a large opening angle and a particularly large ventilation opening to be released for the deployable wing is achieved.
Demgegenüber ist es Auffgäbe 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 angeordneten elektromotorischen Antrieb. Diese Aufgabe wird durch die Lehre des Anspruchs 1 gelöst.In contrast, it is the 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 an electric motor drive arranged in the housing. This object is achieved by the teaching of claim 1.
Mit dieser Lösung wird es möglich, in einem Kettenantriebsgehäuse von begrenzten Abmessungen eine große Länge der für die Aufnahme der Ausstellkette erforderlichen Kettenführung unterzubringen und diese große Länge auch sicher mit dem motorischen Antrieb auszufahren bzw. einzuziehen, weil sich die drei Kettenabschnitte über im wesentlichen gleiche, der Länge des Gehäuses entsprechende, Längen erstecken. Gleichzeitig wird die Antriebsachse des elektromotorischen Antriebes parallel zu den erwähnten drei Kettenführungsabschnitten ausgerichtet und die Einbauhöhe des Antriebsmotors entspricht in etwa der Höhe des Gehäuses. So kann eine kompakte Anordnung von Kettenführungsabschnitten 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.With this solution, it is possible to accommodate a long length of the chain guide required for accommodating the display chain in a chain drive housing of limited dimensions and to extend or retract this long length safely with the motor drive, because the three chain sections extend over essentially the same, cover lengths corresponding to the length of the housing. At the same time, the drive axis of the electric motor drive is aligned parallel to the three chain guide sections mentioned and the installation height of the drive motor corresponds approximately to the height of the housing. A compact arrangement of chain guide sections and electromotive drive can thus be achieved with almost complete use of the space available in the housing without the chain introduced into the housing having to go through tight radii of curvature.
Bevorzugt kann eine wendeiförmige Anordnung der Kettenführung eingesetzt werden, wie dies in der Weiterbildung gemäß der Lehre des Anspruches 3 angegeben ist. Dabei läßt sich eine besonders günstige räumliche und auch für den Betrieb vorteilhafte Anordnung der gesamten Kettenlänge in dem Kettenantriebsgehäuse gemäß der Lehre des Anspruchs 6 erreichen.A helical arrangement of the chain guide can preferably be used, as indicated in the further development according to the teaching of claim 3. A particularly favorable spatial arrangement, which is also advantageous for operation, of the entire chain length in the chain drive housing can be achieved in accordance with the teaching of claim 6.
Zwar ist es aus der AU-A 26 009/77 bereits bekannt, eine wendeiförmige Anordnung mit zwei oder mehr Etagen für die eingeführte Kette vorzusehen, wobei eine Rampe verwendet wird. In diesem Beispiel aus der Stand der Technik wird allerdings das Kettenantriebsritzel seitlich neben den dreiIt is already known from AU-A 26 009/77 to provide a helical arrangement with two or more levels for the inserted chain, using a ramp. In this example from the prior art, however, the chain drive sprocket is on the side next to the three
Kettenführungsabschnitten angeordnet, so daß sich wiederum enge Krümmungsradien ergeben bei gleichzeitig langgestrecktem Gehäuse, ohne daß der elektromotorische Antrieb bei dieser Anordnung Berücksichtigung findet.Chain guide sections arranged so that again there are tight radii of curvature with an elongated housing at the same time, without the electromotive drive being taken into account in this arrangement.
Ein elektromotorischer Antrieb wird auch in Verbindung mit einer Ausführungsform gemäß US 4,481,735 vorgeschlagen, bei der allerdings die in das Gehäuse eingeführte Kette über zwei Endlagenschalter abgetastet wird und nicht einmal drei zueinander parallele Kettenführungsabschnitte im Gehäuse erreicht werden, sondern nur VA zueinander parallele Abschnitte vorgesehen sind. Außerhalb des Gehäuses wird der Motor angeordnet, der mit der senkrecht zu denAn electromotive drive is also proposed in connection with an embodiment according to US 4,481,735, in which, however, the chain inserted into the housing has two Limit switch is scanned and not even three mutually parallel chain guide sections are reached in the housing, but only VA mutually parallel sections are provided. Outside of the housing, the motor is arranged that is perpendicular to the
Kettenführungsabschnitten angeordneten Achse des Antriebsritzels in mechanischer Verbindung steht. Eine kompakte Anordnung einer langen Ausstellkette kann dort nicht erreicht werden. Chain guide sections arranged axis of the drive pinion is in mechanical connection. A compact arrangement of a long display chain cannot be achieved there.
Die Erfindung wird nachfolgend anhand schematischer Zeichnungen an mehreren Ausführungsbeispielen näher erläutert.The invention is explained in more detail below with the aid of schematic drawings using several exemplary embodiments.

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.For easier assembly, the housing 5 consists of at least two housing parts which are firmly connected to one another.
Wie aus Figur 4 und 5 ersichtlich ist, kann das Gehäuse 10 im inneren Bereich Montageelemente 15, 16 zur Anbringung einesAs can be seen from FIGS. 4 and 5, the housing 10 can have mounting elements 15, 16 in the inner region for attaching a
Motors mit Getriebe und Getriebeausgangsritzel und zur Montage eines Kettenantriebsrades aufweisen, wobei die Motorgetriebeachse mit 16a und die Drehachse des Kettenantriebsgliedes 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, 13 und 14, parallel zu den Stirnseiten des Gehäuses erstrecken. Der Abschnitt 14 bildet zugleich denHave motor with gear and transmission output pinion and for mounting a chain drive wheel, the motor gear 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 consists essentially of three arranged parallel to the longitudinal direction of the housing and to each other Chain guide sections 12a, 12b, 12c, the length of which corresponds approximately to the length L of the housing. These length sections are connected to one another by transition sections, two of which, 13 and 14, extend parallel to the end faces of the housing. Section 14 also forms the
Austrittsabschnitt der Kettenführung, deren Austrittsöffnung bei 14a angedeutet ist.Outlet section of the chain guide, the outlet opening of which is indicated at 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 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, as illustrated in FIG. 5, which represents a section along the section line V-V in FIG.
Die Höhe des Gehäuses 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 is determined by the installation height of the actual drive, while the width dimensions of the housing are determined by the longitudinal sections 12a-12c of the chain guide lying next to one another in the same plane.
Bei der Ausführungsform nach Figur 6-8, die bevorzugt ist, 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 Ubergangsabschnitt 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 Gehäuses weitgehend bestimmt. Das gleiche gilt für die Breite und für die Länge des Gehäuses. In the embodiment according to FIGS. 6-8, which is preferred, 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 wheel 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. About the same Distances above and below the level 35 lie in levels 36 and 37 loop-shaped sections of the continuous chain guide 32. 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 housing. The same applies to the width and length of the housing.
