Description

Die Erfindung betrifft einen Sessel mit Aufstehhilfe entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a chair with stand-up aid according to the preamble of claim 1.

Derartige Sessel (siehe z.B. die Druckschriften DE-U-20 2006 016889 und DE-U-297 07 947 ) kommen als Sitz- oder Liegemöbel zum Einsatz, in letzterem Fall üblicherweise als Liegesessel. In dieser Stellung sind das Fußteil in eine Gebrauchsstellung auf und die Rückenlehne in eine Liegestellung abgeschwenkt, wobei sowohl die Rückenlehne wie auch das Fußteil jeweils über einen separaten Motor betätigbar sind.Such chair (see, for example, the publications DE-U-20 2006 016889 and DE-U-297 07 947 ) are used as sitting or lying furniture, in the latter case usually as a reclining chair. In this position, the foot in a position of use and the backrest are pivoted to a reclining position, both the backrest and the foot part are each actuated by a separate motor.

Der Motor zur Verschwenkung des Fußteiles dient auch dem Anheben und Verschwenken des Sesselkörpers in eine Aufstehposition, so dass insbesondere älteren oder behinderten Personen ein Aufstehen aus dem Sessel erleichtert wird.The motor for pivoting the foot also serves to raise and pivot the chair body in a standing position, so that in particular elderly or disabled persons getting up from the chair is facilitated.

Zur getrennten Verschwenkung der Rückenlehne und des Fußteiles sind jeweils separate Antriebe vorgesehen, die als Spindelantriebe ausgebildet sind, wobei mit dem das Fußteil verschwenkenden Spindelantrieb auch der Aufstellbeschlag betreibbar ist.For separate pivoting of the backrest and the foot part each separate drives are provided, which are designed as spindle drives, with the pivoting the foot part spindle drive and the installation fitting is operable.

Die bislang bekannte Konzeption des Aufstellbeschlages bedingt allerdings eine relativ hohe Antriebsleistung des Spindelantriebs, da dieser zur Anhebung und Verschwenkung des Sesselkörpers gegen den Aufstellbeschlag drücken muss. Überdies ist die Krafteinleitung in den Aufstellbeschlag ungünstig, wodurch sich gleichfalls eine höhere notwendige Motorleistung ergibt.However, the previously known conception of Aufstellbeschlages requires a relatively high drive power of the spindle drive, as it must press to raise and pivoting of the chair body against the mounting fitting. Moreover, the introduction of force in the mounting fitting is unfavorable, which also results in a higher required engine power.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Sessel der gattungsgemäßen Art so weiterzuentwickeln, dass seine Funktionsfähigkeit verbessert und die Antriebsdimensionierung optimiert wird.The invention is therefore based on the object, a chair of the generic type so that its functionality improved and the drive sizing is optimized.

Diese Aufgabe wird durch einen Sessel mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a chair with the features of claim 1.

Durch die gegensinnige Verschwenkung des Lenker- und Aufstellhebels und deren Anlenkung an der Antriebsspindel jeweils einer anderen Seite des Antriebs zugeordnet, wird der entsprechende Spindelantrieb beim Anheben und Verschwenken im Sinne der Aufstehhilfe, lediglich auf Zug belastet, wodurch eine geringere Belastung des Antriebs erreicht wird.Assigned by the opposite direction pivoting of the handlebar and raising lever and its linkage to the drive spindle in each case a different side of the drive, the corresponding spindle drive when lifting and pivoting in the sense of standing up, only charged to train, whereby a lower load on the drive is achieved.

Hierzu trägt auch die nun gegebene verbesserte Krafteinleitung in die Antriebsspindel bei, so dass der Spindelantrieb kleiner dimensioniert werden kann.This also contributes to the now given improved introduction of force in the drive spindle, so that the spindle drive can be made smaller.

Darüber hinaus erlaubt die erfindungsgemäße Ausbildung des Aufstellbeschlages eine größere Verfahrgeschwindigkeit des Spindelantriebs, was zur Komforterhöhung des Sessels insgesamt beiträgt.In addition, the inventive design of Aufstellbeschlages allows a greater travel speed of the spindle drive, which contributes to the comfort increase of the chair altogether.

Weiter erlaubt die Erfindung konstruktive Maßnahmen, mit denen mit geringem Aufwand die Funktionssicherheit erhöht wird.Next, the invention allows design measures with which the reliability is increased with little effort.

Hierzu gehört vor allem, dass bei ausgeschwenkter Funktionsstellung des Fußteiles die Aufstehhilfe blockiert ist, so dass eine Beschädigung des Fußteiles durch Fehlbedienung praktisch ausgeschlossen ist.This includes, above all, that when the functional position of the foot part pivots out, the stand-up aid is blocked so that damage to the foot part due to incorrect operation is virtually ruled out.

Andererseits ist die Ausschwenkbarkeit des Fußteiles blockiert, wenn sich die Auf stehhilfe in Funktionsstellung befindet, d.h., der Sesselkörper hochgestellt und nach vorne gekippt ist.On the other hand, the pivotability of the foot is blocked when the upstand is in working position, that is, the chair body is raised and tilted forward.

Nach einer vorteilhaften Weiterbildung der Erfindung ist dazu vorgesehen, am freien Ende des Lenkerhebels, also dem dem Koppelglied abgewandten Ende, eine Lasche drehbar zu befestigen, die gelenkig mit einem Winkelhebel verbunden ist, der an der Antriebsspindel angelenkt ist und so die gelenkige Verbindung zwischen dem Lenkerhebel und der Antriebsspindel schafft.According to an advantageous embodiment of the invention is provided at the free end of the handlebar lever, ie the end remote from the coupling member, rotatably attach a tab which is hingedly connected to an angle lever which is hinged to the drive spindle and so the articulated connection between the Handlebar lever and the drive spindle creates.

Des weiteren ist mit einem Schwenkbeschlag des Fußteiles eine Lenkerlasche verbunden, die an seinem anderen Ende drehbar am Seitenteil angeschlossen ist.Furthermore, a handlebar link is connected to a pivot fitting of the foot part, which is connected at its other end rotatably mounted on the side part.

Bei ausgeschwenktem Fußteil liegen der Anlenkpunkt der Lasche am Lenkerhebel und der Anlenkpunkt der Lenkerlasche am Seitenteil in einer horizontalen Ebene, wodurch eine Blockade des Aufstellbeschlages derart erreicht ist, dass eine Auf schwenkung des Sesselkörpers im Sinne einer Aufstehhilfe nicht möglich ist.When swung foot part of the pivot point of the tab on the handlebar lever and the pivot point of the handlebar lug on the side part in a horizontal plane, whereby a blockage of the Aufstellbeschlages are achieved such that a pivoting on the chair body in terms of a stand-up is not possible.

Andererseits liegt der Anlenkpunkt der Lasche mit dem Lenkerhebel bei einer Auf stehstellung des Sesselkörpers außerhalb des Überdeckungsbereiches mit dem Anlenkpunkt der Lenkerlasche am Seitenteil, wodurch eine Blockade des Fußteiles gegeben ist, durch die auch bei Betätigung des Spindelantriebs das Fußteil nicht verschwenkbar ist.On the other hand, the point of articulation of the tab with the handlebar lever is in a standing position of the chair body outside the coverage area with the articulation point of the handlebar lug on the side part, whereby a blockage of the foot part is given by the foot is not pivotable even when operating the spindle drive.

Da das Fußteil in jedem Fall in Nichtgebrauchsstellung blockiert ist, ergibt sich eine Sicherung beim Transport des Sessels, zumal mit der Festsetzung des Fußteiles auch der Aufstellbeschlag und damit der Standrahmen fest zueinander positioniert sind.Since the foot is blocked in each case in non-use position, there is a backup during transport of the chair, especially with the fixing of the foot and the mounting fitting and thus the stand are firmly positioned to each other.

Nach einem weiteren Gedanken der Erfindung ist vorgesehen, den Aufstellhebel über ein angelenktes Scherenglied mit dem Seitenteil zu verbinden, wobei je nach Schwenkwinkel des Aufstellhebels über das Scherenglied der Sesselkörper an seinem hinteren Ende in die Aufstehposition gehoben wird.According to a further aspect of the invention, it is provided to connect the raising lever via a hinged scissor member with the side part, wherein depending on the pivot angle of the raising lever on the scissor member of the chair body is lifted at its rear end in the standing position.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous embodiments of the invention are characterized in the subclaims.

Ein Ausführungsbeispiel wird nachfolgend anhand der beigefügten Zeichnungen beschrieben.An embodiment will be described below with reference to the accompanying drawings.

In den Figuren ist ein Sessel mit Aufstehhilfe dargestellt, der einen Standrahmen 1 aufweist, an dem mittels eines Aufstellbeschlages 10 ein durch einen elektrischen Spindelantrieb 7 anheb- und kippbarer Sesselkörper 2 angeschlossen ist.In the figures, an armchair is shown with stand-up, which has a stand frame 1, to which by means of a Aufstellbeschlages 10 a by an electric spindle drive 7 liftable and tiltable chair body 2 is connected.

Dieser Sesselkörper 2 weist zwei parallel und abständig zueinander angeordnete Seitenteile 3, ein daran befestigtes Sitzteil 5, eine über einen Motor 8 verschwenkbare Rückenlehne 4 sowie eine durch den Spindelantrieb 7 von einer abgeschwenkten Nichtgebrauchs- (Figuren 2 und 3) in eine aufgeschwenkte Gebrauchsstellung (Figur 1) bewegbare Fußstütze 6 auf.This chair body 2 has two parallel and spaced apart arranged side parts 3, a seat part 5 attached thereto, a pivotable about a motor 8 backrest 4 and a by the spindle drive 7 from a pivoted non-use ( Figures 2 and 3 ) in a pivoted position of use ( FIG. 1 ) movable footrest 6 on.

Erfindungsgemäß ist der Aufstellbeschlag 10 mit einem zweiarmigen Aufstellhebel 12 sowie einem zweiarmigen Lenkerhebel 11 versehen, die gegensinnig zueinander bewegbar und jeweils schwenkbar am Standrahmen 1 befestigt sind.According to the Aufstellbeschlag 10 is provided with a two-armed raising lever 12 and a two-armed handlebar lever 11, which are mounted in opposite directions to each other movable and each pivotally mounted on the frame 1.

Die dem Standrahmen 1 zugewandten Arme des Lenker- und des Aufstellhebels 11, 12 sind durch ein Koppelglied 13 miteinander verbunden.The frame 1 facing arms of the handlebar and the raising lever 11, 12 are connected by a coupling member 13 with each other.

Der andere Arm des Aufstellhebels 12 ist an ein Scherenglied 18 durch eine Zugfeder 19 kraftunterstützend angelenkt, das an einem Seitenteil 3 befestigt ist, wobei die Zugfeder 19 am Aufstellhebel 12 und an dem Scherenglied 18 angreift.The other arm of the raising lever 12 is articulated to a scissor member 18 by a tension spring 19 which is mounted on a side part 3, wherein the tension spring 19 acts on the raising lever 12 and on the scissor member 18.

Der zweite Arm des Lenkerhebels 11 trägt eine Lasche 21, die über ein Drehlager 26 mit dem Lenkerhebel 11 verbunden ist und andererseits an einem Stützlager 25 angeschlossen ist. Dabei ist dieses Stützlager 25 als horizontal ausgerichtetes Rohr ausgebildet, das jeweils einem Seitenteil 3 zugeordnete Beschläge bzw. Beschlagteile miteinander verbindet.The second arm of the handlebar lever 11 carries a tab 21 which is connected via a pivot bearing 26 with the handlebar lever 11 and on the other hand connected to a support bearing 25. In this case, this support bearing 25 is formed as a horizontally oriented tube, each of which connects a side part 3 associated fittings or fittings together.

Der Einfachheit halber werden im folgenden die nur einem Seitenteil 3 zugeordneten Beschlagteile beschrieben, die im wesentlichen jedoch im Bereich beider Seitenteile angeordnet sind, also insbesondere aus Stabilitätsgründen zweifach vorliegen, wobei das genannte Stützlager 25, das die beiden Laschen 21 der beiden Seiten miteinander verbindet, an einem Winkelhebel 17 befestigt ist, der mit einer Antriebsspindel 9 des Spindelantriebs 7 verbunden ist. Die jeweils einem Seitenteil 3 zugeordneten Lenkerhebel 11, die ebenso wie die übrigen zweifach vorhandenen Beschlagteile synchron mit dem jeweils anderen Beschlagteil bewegt werden, sind durch ein Verbindungsrohr 20 miteinander verbunden.For the sake of simplicity, only one side part 3 associated fitting parts will be described in the following, which are arranged substantially in the region of both sides, so in particular two reasons of stability, wherein said support bearing 25, which connects the two tabs 21 of the two sides, is attached to an angle lever 17 which is connected to a drive spindle 9 of the spindle drive 7. Each one side part 3 associated handlebar lever 11, which are moved as well as the other two-fold fitting parts synchronously with the other fitting part, are connected by a connecting tube 20 with each other.

Zwischen der unteren Anlenkung des Lenkerhebels 11 am Standrahmen 1 und dem Drehlager 26 ist der zweite Arm des Lenkerhebels 11 drehbar an einem Haltearm 28 angeschlossen, der wiederum mit einer Befestigungslasche 27, die am Seitenteil 3 befestigt ist, verbunden ist.Between the lower linkage of the handlebar lever 11 on the frame 1 and the pivot bearing 26 of the second arm of the handlebar lever 11 is rotatably connected to a support arm 28 which in turn is connected to a fastening tab 27 which is attached to the side part 3.

Daneben ist an dem Haltearm 28 eine Lenkerlasche 16 angelenkt, die an einem Scherenbeschlag 15 befestigt ist, mit der das Fußteil 6 am Sitzteil 5 angeschlossen ist. Im Verbindungsbereich des Lenkerhebels 11 mit dem Haltearm 28 ist ein Schwenkzapfen 22 vorgesehen, der fest mit dem Seitenteil 3 verbunden ist, so dass sich der Lenkerhebel 11 ebenso wie die angeschlossene Lasche 21 um diesen Schwenkzapfen 22 drehen kann.In addition, a handlebar lug 16 is hinged to the support arm 28, which is fastened to a scissors fitting 15, with which the foot part 6 is connected to the seat part 5. In the connecting region of the handlebar lever 11 with the support arm 28, a pivot pin 22 is provided which is fixedly connected to the side part 3, so that the handlebar lever 11 as well as the connected tab 21 can rotate about this pivot pin 22.

Mittels eines Anschlussbolzens 23 ist die Lenkerlasche 16 am Haltearm 28 schwenkbar festgelegt.By means of a connecting bolt 23, the handlebar lug 16 is pivotally mounted on the support arm 28.

Wie erwähnt, ist der Lenkerhebel 11 über die Lasche 21 und den Winkelhebel 17 am Spindelantrieb 7 befestigt, wobei der Winkelhebel 17 an einem Ende einer Antriebsspindel 9 des Spindelantriebs 7 angreift. Auf der anderen Seite des Spindelantriebs 7 ist auf der Antriebsspindel 9 eine mit dem Spindelantrieb 7 fest verbundene Spindelmutter geführt, an der eine Anschlusslasche 29 befestigt ist, die andererseits am zweiten Arm des Aufstellhebels 12 angelenkt ist.As mentioned, the handlebar lever 11 is attached via the tab 21 and the angle lever 17 on the spindle drive 7, wherein the angle lever 17 engages one end of a drive spindle 9 of the spindle drive 7. On the other side of the spindle drive 7, a spindle nut fixedly connected to the spindle drive 7 is guided on the drive spindle 9, to which a connecting lug 29 is fastened, which on the other hand is articulated on the second arm of the setting lever 12.

In der Figur 1 ist der Sessel in einer Liegeposition dargestellt, in der die Rückenlehne 4 ab- und das Fußteil 6 in eine Gebrauchsstellung aufgeschwenkt sind.In the FIG. 1 the chair is shown in a reclining position in which the backrest 4 off and the foot 6 are pivoted into a position of use.

In dieser Position liegen der Anschlussbolzen 23 und das Drehlager 26 (siehe auch die Figur 3 Ansicht Z) in einer horizontalen Achse übereinander, wodurch bei Betätigung des Spindelantriebs 7 verhindert wird, dass die in dieser Position auseinander gespreizt liegenden Beschlagteile Lenkerhebel 11/Aufstellhebel 12 in eine Stellung verschwenkt werden, in der der Sesselkörper 2 angehoben und nach vorne gekippt werden kann, entsprechend der Figur 3.In this position are the connecting pin 23 and the pivot bearing 26 (see also the FIG. 3 View Z) in a horizontal axis one above the other, which prevents actuation of the spindle drive 7 that spread apart in this position lying fittings handlebar lever 11 / setting lever 12 are pivoted to a position in which the chair body 2 can be raised and tilted forward , according to the FIG. 3 ,

Nach einem Absenken des Fußteiles 6 in eine Nichtgebrauchsstellung, entsprechend der Figur 2, in der auch die Rückenlehne 4 gerade gestellt ist und der Sessel eine sozusagen Sitzstellung einnimmt, wird beim weiteren Verfahren des Spindelantriebs 7 bzw. der Antriebsspindel 9 der Winkelhebel 17 zum Spindelantrieb 7 hin verschwenkt, bis er an dem Verbindungsrohr 20 zur Anlage kommt.After lowering the foot part 6 in a non-use position, according to the FIG. 2 in which also the backrest 4 is straight and the chair occupies a sitting position, so to speak, the angle lever 17 is pivoted to the spindle drive 7 in the further process of the spindle drive 7 and the drive spindle 9 until it comes to rest on the connecting pipe 20.

Beim folgenden weiteren Verfahren des Spindelantriebs 7 wird das Drehlager 26 aus dem Überdeckungsbereich mit dem Anschlussbolzen 23 nach oben hin herausgefahren und durch die Verbindung mittels des Koppelgliedes 13 bei der Verschwenkung des Lenkerhebels 11 der Aufstellhebel 12 aufgeschwenkt, unter Anheben des Möbelkörpers 2, so dass eine Aufstehposition, entsprechend der Figur 3 erreicht wird.In the following further method of the spindle drive 7, the pivot bearing 26 is moved out of the coverage area with the connection pin 23 upwards and swung by the connection by means of the coupling member 13 during the pivoting of the handlebar lever 11 of the set-up lever 12, raising the furniture body 2, so that a Stand up position, according to the FIG. 3 is reached.

Dabei sind der Schwenkzapfen 22, mit dem der Lenkerhebel 11 schwenkbar am Seitenteil befestigt ist, und der Schwenkbolzen 24, mit dem der Winkelhebel 17 drehbar an der Lenkerlasche 16 angeschlossen ist, in einer horizontalen Ebene axial übereinander liegend, wodurch eine Verschwenkung des Fußteiles 6 in dieser Auf stehposition verhindert wird.In this case, the pivot pin 22, with the handlebar lever 11 is pivotally mounted on the side part, and the pivot pin 24, with the angle lever 17 is rotatably connected to the handlebar lug 16, axially superimposed in a horizontal plane, thereby pivoting the foot part 6 in This upright position is prevented.
