Definitions
- the present invention relates to a Schrägraffstore with a drive and elevator rollers on which elevator members are wound on which a Lamellenbehang is suspended, wherein the provided on the lower side of Schrägraffstores elevator roller from the drive by means of a switching device can be decoupled.
- the switching device may be formed in such a way that it has a multi-stage planetary gear, the gear stages each having a sun gear, with this meshing planetary gears, a planet carrier supporting them and a ring gear, wherein the winding roller is rotationally coupled to the ring gear of the last gear stage and in the last gear stage between the ring gear and the sun gear or the planet carrier a rotation stop is provided which limits the relative rotation of the ring gear to the planet carrier or sun gear of the last gear, so that when adjacent rotation stop the drive entrains the elevator pulley.
- the object of the invention is to provide a Schrägraffstore with a planetary gear, which can be easily integrated into the upper rail of the system.
- the object is achieved by a Schrägraffstore according to claim 1, wherein the winding roller of the lower side of the plant is arranged on the outer circumference of the ring gear of the last gear stage.
- the ring gears had an outer diameter, which was well above the core diameter of the Auszugsrollen, it has surprisingly been found that it is possible with the inventive design of ring gears and elevator role to arrange them axially practically congruent and thereby the axial space requirement considerably to diminish.
- the planetary gear stages therefore have radial dimensions, which nevertheless allow a design of the elevator pulley with a sufficiently small core diameter on the outer circumference of the ring gears. This makes it possible to integrate the multi-stage planetary gear in the top rail of Schrägraffstores, so that no drive parts more protrude laterally from the rail profile and are exposed to the risk of damage.
- a two-stage planetary gear which is a first, rotationally connected to the drive sun gear, a combing with this set of first planet gears, which are mounted on a first planet carrier, a rotationally connected thereto second sun , Having a meshing with this set of second planetary gears and a second planetary carrier to the storage.
- a two-stage planetary gear which is a first, rotationally connected to the drive sun gear, a combing with this set of first planet gears, which are mounted on a first planet carrier, a rotationally connected thereto second sun , Having a meshing with this set of second planetary gears and a second planetary carrier to the storage.
- the ring gears of the gear stages are rotationally connected to each other.
- about the ring gears and a bearing of the planetary gear is possible.
- the winding roller is arranged axially between the planetary gear sets.
- This embodiment allows the core diameter of the winding roll between the two ring gears, in which the planetary gear sets mesh, radially to draw relatively far inward, without weakening the ring gears.
- the thus possible slightly enlarged outer diameter of the ring gears has a favorable effect on the strength properties, so that less expensive materials for the gears can be used.
- the drive acts in each case via a bevel gear on the elevator rollers, so that they lie with their axes of rotation perpendicular to the shaded wall opening.
- the inventive design of the two-stage planetary gearset allows even in this embodiment to integrate all the parts within the upper rail, although Also, the bevel gear still requires a certain axial space in the region of the axis of rotation of the elevator rollers.
- the advantage of the described arrangement of the elevator rollers is that an entanglement of the elevator members, which are usually designed as elevator belts, in the region of the exit point from the upper rail is not required.
- the ring gears and the elevator pulley can be made in one piece on the lower side of the system, but should an increased strength requirement exist for the teeth, but it is also readily conceivable that ring gears are designed as separate insert elements sitting in inner peripheral surfaces of the elevator pulley.
- the rotation stop is formed on a disc which cooperates with a shoulder on the ring gear, wherein it can be fixed to the second planetary carrier, for example by a releasable clamping seat or a toothing with a sufficiently small tooth width, or even the second Planet carrier forms.
- a so-called elevator bearing 10 an oblique firing system (not shown) is shown, as it comes on the lower-lying plant side used.
- the elevator bearing 10 is mounted in an upper rail and connected via a drive shaft 12 with a drive, not shown.
- the drive shaft 12 also drives a turning device 14 (see Fig. 2 . 5 and 6 ), which acts via a ladder cord 16, on which the slats are suspended, on the curtain to adjust different slat tilt positions can.
- the turning device is known as such and should therefore not be discussed further here.
- the elevator bearing 10 has a housing 18 with a base 20 and a lid 22, which in Fig. 2 is removed to allow insight into the interior of the elevator bearing 10.
- the drive shaft 12 is rotationally connected to a bevel pinion 24, which is in engagement with a bevel gear 26.
- the axis of rotation of the Kegeltellerrades 26 is perpendicular to the surface of the slat slope or perpendicular to the wall opening, which is to be shadowed by the Schrägraffstore.
- an elevator pulley 28 is disposed coaxially with the bevel gear 26.
- Lifting tape wound which is connected to the fall profile of the Lamellenbehangs and with the help of the curtain is einholbar. Since the entry length on the lower side of the system is naturally smaller than on the higher side of the plant, the rotational connection between the bevel gear 26 and the elevator pulley 28 must be interrupted at an appropriate time, the drive then only drives the elevator pulley on the higher side of the plant.
- the drive should first be made exclusively on the higher side of the installation until the fall profile has reached a slope corresponding to the upper rail.
- a switching device 30 between the bevel gear wheel 26 and the elevator pulley 28 then establishes the rotational lock between these two parts, so that in a further catching up also takes place on the lower side of the plant.
- the exact structure and function of the designed as a two-stage planetary gearbox switching device 30 is off 4 to 6 seen.
- the bevel gear 26 is rotationally rigidly connected to an input shaft 32 which extends through the entire planetary gear drive.
- the input shaft 32 is formed with a first sun gear 34 (see Fig. 5 ), which lies in spatial axial proximity to the conical disk wheel 26.
- a first sun gear 34 (see Fig. 5 )
- the first sun gear 34 With three planet wheels 36 which are rotatably mounted in each case a first planet carrier 38.
- the planetary gears 36 further mesh in a ring gear 40.
- the planet carrier 38 is rotationally rigidly connected to a hollow shaft 42, which on the outer circumference of the input shaft 32 relative is mounted rotatably to this.
- the hollow shaft 42 is in its outer periphery with a second sun gear 44 for the second gear stage (see Fig. 6 ) which engages a second set of planet wheels 46, which in turn mesh in a ring gear 48.
- the planet gears 46 are each rotatably mounted on a second planet carrier 50 which is formed as a disc and at its periphery with a radial projection 52 (see Figure 3 ) is formed, which cooperates with an axial projection 54 of the ring gear 48 and forms a rotation stop, which limits the relative rotation between the ring gear 48 and the second planetary carrier 50.
- both ring gears 40, 48 and the winding roller 28 are made as a one-piece part, for example, zinc die casting, ie, both the ring gear 40 of the first gear stage and the ring gear 48 of the second gear 48 are rigidly connected.
- the winding roller is located centrally between the two gear stages and their core diameter 56 is displaced radially inwards, whereby a sufficiently small core diameter 56 for the winding roller 28 can be combined with a diameter of larger diameter for the ring gears 40, 48 that is advantageous for reasons of strength ,
- the planetary gear shown has the advantage that the rotation stop between the second planet carrier 50 and the ring gears always remains closed, as long a load is introduced into the elevator pulley 28 via the elevator belt. But as soon as the drop profile moves against a stop, for example an end stop in the extended end position, the elevator roller 28 stops and the radial projection 52 moves away from the axial projection 54 until the drop profile of the curtain reaches the extended end position also on the higher side of the system.
- the planetary gear with the arranged on the outer circumference of the ring gears 40, 48 elevator pulley 28 is designed to save space and can be easily integrated into the elevator bearings without parts projecting laterally or a particularly large wound reel diameter would be required.

Description
Die vorliegende Erfindung befasst sich mit einem Schrägraffstore mit einem Antrieb und Aufzugsrollen, auf denen Aufzugsorgane aufwickelbar sind, an denen ein Lamellenbehang aufgehängt ist, wobei die an der tiefer liegenden Seite des Schrägraffstores vorgesehene Aufzugsrolle vom Antrieb mit Hilfe einer Schalteinrichtung abkoppelbar ist. Die Schalteinrichtung kann in der Weise ausgebildet sein, dass sie ein mehrstufiges Planetengetriebe besitzt, dessen Getriebestufen jeweils ein Sonnenrad, mit diesem kämmende Planetenräder, einen diese lagernden Planetenträger sowie ein Hohlrad aufweisen, wobei die Aufzugsrolle mit dem Hohlrad der letzten Getriebestufe drehschlüssig gekoppelt ist und in der letzten Getriebestufe zwischen dem Hohlrad und dem Sonnenrad oder dem Planetenträger ein Drehanschlag vorgesehen ist, der die relative Verdrehung des Hohlrades zu dem Planetenträger oder Sonnenrad der letzten Getriebestufe begrenzt, so dass bei anliegendem Drehanschlag der Antrieb die Aufzugsrolle mitnimmt.The present invention relates to a Schrägraffstore with a drive and elevator rollers on which elevator members are wound on which a Lamellenbehang is suspended, wherein the provided on the lower side of Schrägraffstores elevator roller from the drive by means of a switching device can be decoupled. The switching device may be formed in such a way that it has a multi-stage planetary gear, the gear stages each having a sun gear, with this meshing planetary gears, a planet carrier supporting them and a ring gear, wherein the winding roller is rotationally coupled to the ring gear of the last gear stage and in the last gear stage between the ring gear and the sun gear or the planet carrier a rotation stop is provided which limits the relative rotation of the ring gear to the planet carrier or sun gear of the last gear, so that when adjacent rotation stop the drive entrains the elevator pulley.
Ein derartiger Schrägraffstore ist bereits bekannt und besitzt gegenüber älteren Varianten mit reibschlüssigen Kupplungen als Schaltvorrichtungen, wie sie beispielsweise aus der
Problematisch bei dem Einsatz von Planetenanschlaggetrieben ist, dass diese einen erheblichen Raumbedarf haben, so dass sie sich in den möglichst schlank gehaltenen Oberschienen von Raffstoreanlagen nur schwer integrieren lassen. Bei den bekannten Ausführungsformen ist es daher notwendig, das Planetenanschlaggetriebe außerhalb des Schienenprofils der Oberschiene anzuordnen, so dass es optisch störend in Erscheinung tritt und bei einem Transport der Anlage leicht beschädigt werden kann. Wenn die Anlage mit einer Blende abgedeckt wird, ist baulich eine entsprechend große Tiefe vorzusehen.The problem with the use of planetary gear drives is that they have a considerable space requirement, so that they can be integrated into the slender top rails of external venetian blind systems as slender as possible. In the known embodiments, it is therefore necessary to arrange the planetary stop gear outside of the rail profile of the upper rail, so that it appears optically disturbing in appearance and can be easily damaged during transport of the system. If the system is covered with a diaphragm, a correspondingly large depth is structurally provided.
Die Aufgabe der Erfindung besteht darin, einen Schrägraffstore mit einem Planetenanschlaggetriebe zu schaffen, das sich leichter in die Oberschiene der Anlage integrieren lässt.The object of the invention is to provide a Schrägraffstore with a planetary gear, which can be easily integrated into the upper rail of the system.
Erfindungsgemäß wird die Aufgabe durch einen Schrägraffstore nach Anspruch 1 gelöst, bei welchem die Aufzugsrolle der tiefer liegenden Anlagenseite am Außenumfang des Hohlrades der letzten Getriebestufe angeordnet ist.According to the invention the object is achieved by a Schrägraffstore according to claim 1, wherein the winding roller of the lower side of the plant is arranged on the outer circumference of the ring gear of the last gear stage.
Während bei den bekannten Varianten die Hohlräder einen Außendurchmesser besaßen, der deutlich über dem Kerndurchmesser der Auszugsrollen lag, hat es sich überraschenderweise gezeigt, dass es mit der erfindungsgemäßen Ausbildung von Hohlrädern und Aufzugsrolle möglich ist, diese axial praktisch deckungsgleich anzuordnen und dadurch den axialen Raumbedarf erheblich zu vermindern. Die Planetengetriebestufen besitzen daher radiale Abmessungen, die dennoch eine Ausbildung der Aufzugsrolle mit hinreichend kleinem Kerndurchmesser am Außenumfang der Hohlräder ermöglichen. Dadurch ist es möglich, das mehrstufige Planetenanschlaggetriebe in der Oberschiene des Schrägraffstores zu integrieren, so dass keine Antriebsteile mehr aus dem Schienenprofil seitlich hervorstehen und der Gefahr von Beschädigungen ausgesetzt sind.While in the known variants, the ring gears had an outer diameter, which was well above the core diameter of the Auszugsrollen, it has surprisingly been found that it is possible with the inventive design of ring gears and elevator role to arrange them axially practically congruent and thereby the axial space requirement considerably to diminish. The planetary gear stages therefore have radial dimensions, which nevertheless allow a design of the elevator pulley with a sufficiently small core diameter on the outer circumference of the ring gears. This makes it possible to integrate the multi-stage planetary gear in the top rail of Schrägraffstores, so that no drive parts more protrude laterally from the rail profile and are exposed to the risk of damage.
Ausreichend lange Verstellwege im Bereich des Drehanschlages können bereits mit einem zweistufigen Planetenanschlaggetriebe erreicht werden, das ein erstes, mit dem Antrieb drehschlüssig verbundenes Sonnenrad, einen mit diesem kämmenden Satz erster Planetenräder , die an einem ersten Planetenträger gelagert sind, ein mit diesem drehschlüssig verbundenes zweites Sonnenrad, einen mit diesem kämmenden Satz zweiter Planetenräder sowie einen zweiten Planetenträger zu deren Lagerung aufweist. Besonders bevorzugt ist dabei eine Ausführungsform, bei welcher die Hohlräder der Getriebestufen drehschlüssig miteinander verbunden sind. Über die Hohlräder ist auch eine Lagerung des Planetengetriebes möglich.Sufficiently long adjustment in the field of rotation stop can be achieved with a two-stage planetary gear, which is a first, rotationally connected to the drive sun gear, a combing with this set of first planet gears, which are mounted on a first planet carrier, a rotationally connected thereto second sun , Having a meshing with this set of second planetary gears and a second planetary carrier to the storage. Particularly preferred is an embodiment in which the ring gears of the gear stages are rotationally connected to each other. About the ring gears and a bearing of the planetary gear is possible.
In einer besonders bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Wickelrolle axial zwischen den Planetenradsätzen angeordnet ist. Diese Ausführungsform erlaubt es, den Kerndurchmesser der Wickelrolle zwischen den beiden Hohlrädern, in denen die Planetenradsätze kämmen, radial relativ weit nach innen zu ziehen, ohne die Hohlräder zu schwächen. Der dadurch mögliche etwas vergrößerte Außendurchmesser der Hohlräder wirkt sich günstig auf die Festigkeitseigenschaften aus, so dass weniger teure Werkstoffe für die Verzahnungen zum Einsatz kommen können.In a particularly preferred embodiment of the invention, it is provided that the winding roller is arranged axially between the planetary gear sets. This embodiment allows the core diameter of the winding roll between the two ring gears, in which the planetary gear sets mesh, radially to draw relatively far inward, without weakening the ring gears. The thus possible slightly enlarged outer diameter of the ring gears has a favorable effect on the strength properties, so that less expensive materials for the gears can be used.
In einer weiter bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass der Antrieb jeweils über ein Kegelradgetriebe auf die Aufzugsrollen wirkt, so dass diese mit Ihren Drehachsen senkrecht zur verschatteten Maueröffnung liegen. Die erfindungsgemäße Ausbildung des zweistufigen Planetenanschlaggetriebes erlaubt es sogar bei dieser Ausführungsform, sämtliche Teile innerhalb der Oberschiene zu integrieren, obgleich auch die Kegelradstufe noch einen gewissen axialen Bauraum im Bereich der Drehachse der Aufzugsrollen benötigt. Der Vorteil der beschriebenen Anordnung der Aufzugsrollen besteht darin, dass eine Verschränkung der Aufzugsorgane, die in der Regel als Aufzugsbänder ausgebildet sind, im Bereich der Austrittsstelle aus der Oberschiene nicht erforderlich ist.In a further preferred embodiment of the invention, it is provided that the drive acts in each case via a bevel gear on the elevator rollers, so that they lie with their axes of rotation perpendicular to the shaded wall opening. The inventive design of the two-stage planetary gearset allows even in this embodiment to integrate all the parts within the upper rail, although Also, the bevel gear still requires a certain axial space in the region of the axis of rotation of the elevator rollers. The advantage of the described arrangement of the elevator rollers is that an entanglement of the elevator members, which are usually designed as elevator belts, in the region of the exit point from the upper rail is not required.
Je nach Anforderungen können die Hohlräder und die Aufzugsrolle auf der niedrigeren Anlageseite einstückig gefertigt sein, sollte für die Verzahnung aber ein erhöhter Festigkeitsbedarf bestehen, ist es aber auch ohne weiteres denkbar, dass Hohlräder als separate Einsatzelemente ausgebildet sind, die in Innenumfangsflächen der Aufzugsrolle sitzen.Depending on the requirements, the ring gears and the elevator pulley can be made in one piece on the lower side of the system, but should an increased strength requirement exist for the teeth, but it is also readily conceivable that ring gears are designed as separate insert elements sitting in inner peripheral surfaces of the elevator pulley.
Vorteilhaft ist eine Ausführungsform, bei welcher der Drehanschlag an einer Scheibe ausgebildet ist, die mit einem Absatz an dem Hohlrad zusammenwirkt, wobei sie an dem zweiten Planetenträger festlegbar ist, beispielsweise durch einen lösbaren Klemmsitz oder eine Verzahnung mit hinreichend kleiner Zahnbreite, oder selbst den zweiten Planetenträger bildet.Advantageous is an embodiment in which the rotation stop is formed on a disc which cooperates with a shoulder on the ring gear, wherein it can be fixed to the second planetary carrier, for example by a releasable clamping seat or a toothing with a sufficiently small tooth width, or even the second Planet carrier forms.

Entsprechend dieser Darstellung ist zu erkennen, dass die Antriebswelle 12 drehschlüssig mit einem Kegelritzel 24 verbunden ist, das mit einem Kegeltellerrad 26 in Eingriff steht. Die Drehachse des Kegeltellerrades 26 steht senkrecht zur Fläche des Lamellenhangs bzw. senkrecht zur Maueröffnung, die durch den Schrägraffstore verschattet werden soll.According to this representation, it can be seen that the

Der Planetenträger 38 ist drehstarr mit einer Hohlwelle 42 verbunden, die auf dem Außenumfang der Eingangswelle 32 relativ zu dieser verdrehbar gelagert ist. Die Hohlwelle 42 ist in ihrem Außenumfang mit einem zweiten Sonnenrad 44 für die zweite Getriebestufe (siehe
Wie aus
Im Gegensatz zu Schaltkupplungen, die immer nur zu einem bestimmten Schaltpunkt beispielsweise in Abhängigkeit von der Anzahl von Umdrehungen der Antriebswelle 12 schalten können, besitzt das gezeigte Planetenschlaggetriebe den Vorteil, dass der Drehanschlag zwischen dem zweiten Planetenträger 50 und den Hohlrädern immer dann geschlossen bleibt, solange eine Last über das Aufzugsband in die Aufzugsrolle 28 eingeleitet wird. Sobald das Fallprofil aber gegen einen Anschlag fährt, beispielsweise einen Endanschlag in der ausgefahrenen Endposition, bleibt die Aufzugsrolle 28 stehen und der Radialvorsprung 52 entfernt sich vom Axialvorsprung 54, bis auch auf der höheren Anlagenseite das Fallprofil des Behangs die ausgefahrene Endstellung erreicht hat. Damit vereinfachen sich Einstellmaßnahmen und darüber hinaus besitzt das Planetenanschlaggetriebe den Vorteil, dass bei einem unbeabsichtigten Verklemmen auf der niedrigeren Anlagenseite ebenfalls ein Lösen des Drehanschlages erfolgt und die Aufzugsrolle 28 ohne weiteres Abwickeln von Bandvorrat stehenbleibt. Beim Wiederauffahren wird der Behang dann wieder in der richtigen Position mitgenommen, wenn nämlich bei umgekehrter Drehrichtung des Antriebes der Radialvorsprung 52 wieder gegen den axialen Vorsprung 54 läuft.In contrast to clutches that can always switch only to a certain switching point, for example, depending on the number of revolutions of the
Wie aus den Abbildungen gut zu erkennen ist, ist das Planetenanschlaggetriebe mit der am Außenumfang der Hohlräder 40, 48 angeordneten Aufzugsrolle 28 sehr raumsparend ausgebildet und lässt sich ohne weiteres in das Aufzugslager integrieren, ohne dass Teile seitlich hervorstehen oder eine besonders großer Wickelrollendurchmesser erforderlich wäre.As can be clearly seen from the figures, the planetary gear with the arranged on the outer circumference of the ring gears 40, 48
