Description

Die Erfindung betrifft Möbelelemente, die über Hebe- und Führungselemente fest mit einer Wand verbunden sind und die einzeln oder gemeinsam zwischen einer oberen und einer unteren Endlage mittels eines Antriebes verstellbar sind.The invention relates to furniture elements which are firmly connected to a wall by means of lifting and guiding elements and which can be adjusted individually or jointly between an upper and a lower end position by means of a drive.

Es sind bereits Lösungen bekannt, die das Absenken von Schrankmöbeln gestatten. So wird beispielsweise nach der deutschen Patentschrift DE 3613530 ein an einer senkrechten Wand montierbares Schrankmöbel vorgeschlagen, daß zwischen einer oberen wandnahen Endlage und einer unteren wandfernen Endlage parallel zur Montagewand verstellbar ist. Erfindungsgemäß wird dazu an einer Basisplatte mindestens eine Führungseinrichtung befestigt, die wiederum aus zwei Führungselementen besteht, die einerseits an der Basisplatte angeordnet, andererseits mit dem Schrank verbunden ist.Solutions are already known which allow cabinet furniture to be lowered. For example, according to the German patent DE 3613530, a cabinet that can be mounted on a vertical wall is proposed that can be adjusted parallel to the mounting wall between an upper end position near the wall and a lower end position remote from the wall. For this purpose, according to the invention, at least one guide device is attached to a base plate, which in turn consists of two guide elements which are arranged on the one hand on the base plate and on the other hand connected to the cabinet.

Abwandlungen der erfindsgemäßen Lösung verwenden Führungsplatten zwischen denen in Bewegungsrichtung des Schrankes Führungsprofile laufen. Eine weitere Variante benutzt als Führungseinrichtung Lenkerpaare, deren Lenkerarme an der Basisplatte und am Schrank angebracht sind.Modifications of the solution according to the invention use guide plates between which guide profiles run in the direction of movement of the cabinet. Another variant uses pairs of handlebars as guide means, the handlebar arms of which are attached to the base plate and to the cabinet.

Diesen Lösungen ist gemeinsam, daß die Führungseinrichtung seitlich am bewegbaren Schrankmöbel angeordnet ist und eine Seitenwand benötigt, die mit der Basisplatte fest verbunden ist.These solutions have in common that the guide device is arranged laterally on the movable cabinet furniture and requires a side wall which is firmly connected to the base plate.

Zum Anheben und Ansenken der Schrankmöbel sind fluidbetätigte Zylindertriebe vorgesehen, die jeweils innerhalb der Schrankmöbel eingebaut sind.Fluid-actuated cylinder drives are provided for lifting and lowering the cabinet furniture, which are each installed within the cabinet furniture.

Nachteil dieser Lösungen ist, daß der bewegbare Schrankmöbelraum durch diese Maßnahmen eingeschränkt wird. Zudem ist bei der vorgeschlagenen Lösung nachteilig die seitliche Anbringung der Führungseinrichtung, die zu erheblichen Umbauten bzw. Änderungen am Schrankmöbel zwingt.The disadvantage of these solutions is that the movable cabinet furniture space is restricted by these measures. In addition, the lateral solution of the guide device is disadvantageous in the proposed solution considerable conversions or changes to the cabinet furniture.

Der Erfindung liegt daher die Aufgabe zugrunde, in ihrer Höhe wahlweise verstellbare Möbelelemente, die einzeln oder gemeinsam bewegt werden, zu entwickeln, die ohne seitlichen Platzverlust und Platzverlust in den für die Benutzer wichtigen, unteren bewegbaren Möbelelementen, auskommen.The invention is therefore based on the object of developing height-adjustable furniture elements which can be moved individually or jointly and which manage without lateral space loss and space loss in the lower movable furniture elements which are important for the users.

Die bewegbaren Möbelelemente sollen zudem aus der üblichen Serienfertigung stammen. Sie sind somit ohne Umbauten und Einbauten versehen und in allen üblicherweise angebotenen Varianten einsetzbar.The movable furniture elements should also come from the usual series production. They are therefore provided without conversions and internals and can be used in all commonly offered variants.

Die Bewegungsvorrichtungen sind verdeckt anzubringen, um den optischen Eindruck gegenüber einem üblichen Möbelelement nicht zu verschlechtern und sollen anspruchsvoll, wartungsfrei und geräuscharm gestaltet sein.The movement devices are to be installed in a concealed manner so as not to impair the visual impression compared to a conventional furniture element and should be designed to be sophisticated, maintenance-free and quiet.

Durch leichte Montage der zusätzlich erforderlichen Hebe- und Führungseinrichtung ist der gegenüber den üblichen Möbelelementen größere Aufwand zu verringern.By easily assembling the additionally required lifting and guiding device, the greater effort compared to the usual furniture elements can be reduced.

Die erfindungsgemäße Aufgabe wird dadurch gelöst, daß die Möbelelemente (2) durch eine Hebe- und Führungsvorrichtung, durch die sie mit einer senkrechten Wand verbunden sind, einzeln oder gemeinsam zwischen einer oberen wandnahen und einer unteren wandfernen Endlage mittels eines Antriebes (5) verstellbar sind. ( Fig.1,2,3 )The object of the invention is achieved in that the furniture elements (2) can be adjusted individually or together between an upper end position near the wall and a lower end position remote from the wall by means of a drive (5) by means of a lifting and guiding device by which they are connected to a vertical wall . (Fig. 1,2,3)

Die Hebevorrichtung besteht aus einem Antrieb ( 5 ), den Drehpunkten ( 4 ), ( 7 ), die fest mit der Grundplatte ( 1 ) verbunden sind, den Drehelementen ( 6 ) und ( 8 ), zur Verbindung der Koppelglieder ( A ) und ( B ), einer gemeinsamen Befestigungsvorrichtung ( 23 ), die mit dem Drehpunkt ( 17 ) fest verbunden ist.The lifting device consists of a drive (5), the pivot points (4), (7), which are firmly connected to the base plate (1), the rotating elements (6) and (8), for connecting the coupling links (A) and ( B), a common fastening device (23) which is connected to the fulcrum (17) is firmly connected.

Die Führungsvorrichtung besteht aus Koppelgliedern ( C ) und den Drehpunkten ( 13 ), ( 18 ) und ( 22 ), die mit der Grundplatte ( 1 ) sowie den Drehpunkten ( 12 ), ( 19 ) und ( 21 ), die mit der Befestigungsvorrichtung ( 23 ) verbunden sind.The guide device consists of coupling links (C) and the pivot points (13), (18) and (22), which are connected to the base plate (1) and the pivot points (12), (19) and (21), which are connected to the fastening device ( 23) are connected.

Die bewegbaren Möbelelemente ( 2 ) werden wahlweise durch einen Antrieb ( 5 ) elektrisch, pneumatisch oder hydraulisch bewegt und sind über Fernsteuerungsschalter in an sich bekannter Weise schaltbar.The movable furniture elements (2) are optionally moved electrically, pneumatically or hydraulically by a drive (5) and can be switched via remote control switches in a manner known per se.

Die Hebevorrichung ist in einem fest mit der Wand montierten Möbelelement ( 3 ) oberhalb des in der Höhe beweglich verstellbaren Möbelelementes ( 2 ) untergebracht.The lifting device is accommodated in a furniture element (3) fixed to the wall above the height-adjustable furniture element (2).

Die Befestigung des Antriebes ( 5 ) befindet sich in Punkt ( 4 ). Vorzugsweise ist der Antrieb mit einem Spindelgewinde ausgestattet. Der Antrieb bewegt dazu das Spindelgewinde derart, daß in Antriebsrichtung die entsprechende Spindel entweder auf oder ab bewegt wird.The drive (5) is fastened in point (4). The drive is preferably equipped with a spindle thread. For this purpose, the drive moves the spindle thread in such a way that the corresponding spindle is either moved up or down in the drive direction.

Über den Drehpunkt ( 7 ), der mit der Grundplatte ( 1 ) fest verbunden ist, wird die Kraft über Koppelglieder ( A ) und ( B ) über das Drehelement ( 8 ) und den Drehpunkt ( 17 ) auf die Befestigungsvorrichtung ( 23 ) übertragen. Das Koppelglied ( B ) ist dabei über den Drehpunkt ( 17 ) und der Befestigungsvorrichtung ( 23 ) mit dem Möbelelement ( 2 ) fest verbunden.Via the fulcrum (7), which is firmly connected to the base plate (1), the force is transmitted via coupling elements (A) and (B) via the rotating element (8) and the fulcrum (17) to the fastening device (23). The coupling member (B) is firmly connected to the furniture element (2) via the pivot point (17) and the fastening device (23).

Die Führungsvorrichtung kann wahlweise derart ausgebildet sein, daß die Koppelglieder ( C ) parallel zueinander angeordnet und mittels eines Koppelgliedes ( D ) über die Drehelemente ( 20 ) verbunden sind. ( Fig.1 ) Andererseits besteht die Möglichkeit zwischen dem Drehpunkt ( 24 ), der fest mit der Grundplatte ( 1 ) verbunden ist und dem Drehelement ( 20 ) ein Dämpfungselement ( E ) anzuordnen. Das Dämpfungselement ( E ) wirkt vorteil hafterweise kraftentlastend.The guide device can optionally be designed such that the coupling elements (C) are arranged parallel to one another and are connected by means of a coupling element (D) via the rotating elements (20). (Fig.1) On the other hand, there is the possibility of arranging a damping element (E) between the pivot point (24), which is firmly connected to the base plate (1), and the rotating element (20). The damping element (E) advantageously has a force-relieving effect.

Eine weitere Ansführungsform der Führungsvorrichtung besteht darin, daß die Koppelglieder ( C ) scherengitterförmig angeordnet und über das Drehelement ( 16 ) miteinander verbunden sind ( Fig. 3 ).Another embodiment of the guide device is that the coupling links (C) are arranged in a scissor-lattice shape and are connected to one another via the rotary element (16) (FIG. 3).

Vorteilhafterweise kann die Grundplatte ( 1 ) in Fig. 2 eine für alle Anwendungsfälle einheitliche Größe erhalten.The base plate (1) in FIG. 2 can advantageously have a size that is uniform for all applications.

Die Grundplatte ist mit der Hebe- und Führungsvorrichtung verbunden. Damit sind Hebe- und Führungsvorrichtung möglich, die auf wirtschaftlich sinnvolle Art vorgefertigt und wahlweise einzeln oder in größerer Anzahl, aber unabhängig voneinander, auf einfache Weise an der Montagewand befestigt werden können.The base plate is connected to the lifting and guiding device. This makes lifting and guiding devices possible, which can be prefabricated in an economically sensible manner and optionally attached to the mounting wall in a simple manner, either individually or in large numbers, but independently of one another.

Die Hebevorrichtung wird in der beanspruchten Form in einem fest mit der Wand montierten Möbelelement ( 3 ) untergebracht, das oberhalb des in der Höhe verstellbaren Möbelelementes ( 2 ) liegt. Aufgrund dieser Anordnung wird gewährleistet, daß lediglich das feststehende Möbelelement ( 3 ), das für den hier vorrangig angesprochenen Benutzer ( z.B. Behinderte ) nur schwer erreichbar ist, mit den notwendigen Hebevorrichtungen räumlich belastet wird.In the form claimed, the lifting device is accommodated in a furniture element (3) which is fixed to the wall and which is above the height-adjustable furniture element (2). This arrangement ensures that only the fixed furniture element (3), which is difficult to reach for the user primarily addressed here (e.g. disabled people), is spatially loaded with the necessary lifting devices.

Eine besondere Ansgestaltung der Erfindung wird durch die Befestigungsvorrichtung ( 23 ) ermöglicht. Über die mit ihr verbunden Drehpunkte ( 12 ), ( 17 ) und ( 19 ) werden die gemeinsame Verbindung von Hebe- und Führungsvorrichtungen erreicht und gleichzeitig die Befestigung und stabile Fürung der bewegbaren Möbelelemente ( 2 ) gewährleistet. Umbauten an den Möbelelmenten werden ausgeschlossen, da lediglich rückseitig an die Möbelelemente die Befestigungsvorrichtung ( 23 ) angebracht wird.A special design of the invention is made possible by the fastening device (23). Via the pivot points (12), (17) and (19) connected to it, the joint connection of lifting and guiding devices is achieved and at the same time the fastening and stable guidance of the movable furniture elements (2) is ensured. Modifications to the furniture elements are excluded, since the fastening device (23) is only attached to the rear of the furniture elements.

Die Erfindung wird an den nachfolgenden Ansführungsbeispielen näher erläutert:The invention is explained in more detail in the following examples:

Beispiel 1: ( Fig.1 ) Example 1: (Fig.1)

In der Ausgangsstellung befindet sich das bewegliche Möbelelement ( 2 ) unterhalb des fest angebrachten Möbelelementes ( 3 ). Durch Einfahren des Antriebes wird das Koppelglied ( A ) um den Drehpunkt ( 7 ) derart bewegt, daß der Punkt ( 8a ) und der Drehpunkt ( 17a ) in die Position ( 8b ) bzw. ( 17b ) gebracht wird.In the starting position, the movable furniture element (2) is located below the fixed furniture element (3). By retracting the drive, the coupling member (A) is moved around the pivot point (7) in such a way that the point (8a) and the pivot point (17a) are brought into the positions (8b) and (17b).

Dabei legt das Möbelelement ( 2 ) den in der Abbildung Fig. 1 vorbezeichneten Weg zurück. Damit befindet sich das Möbelelement ( 2 ) in der unteren wandfernen Stellung.The furniture element (2) travels the way described in Figure 1. The furniture element (2) is thus in the lower position away from the wall.

Um eine parallele Zwangsführung des Möbelelementes ( 2 ) zu gewährleisten, wird das Koppelglied ( C ) der Führungsvorrichtung, das über Drehpunkt ( 18 ) an der Grundplatte ( 1 ) fixiert ist, über die Drehpunkte ( 19a ) aus seiner Ansgangslage in die Endlage ( 19b ) geführt.In order to ensure a parallel positive guidance of the furniture element (2), the coupling member (C) of the guide device, which is fixed to the base plate (1) via pivot point (18), is moved from its initial position into the end position (19b) via the pivot points (19a) ) guided.

Die Koppelglieder ( C ) geben dadurch den für die Möbelelementführung notwendigen Weg vor.The coupling links (C) thereby specify the path necessary for the furniture element guide.

Beispiel 2: ( Fig.3 ) Example 2: (Fig.3)

Die Bewegung des Möbelelmentes ( 2 ) erfolgt zunächst über den Antrieb ( 5 ), wie im Beispiel 1 ( Fig.1 ).The furniture element (2) is first moved via the drive (5), as in example 1 (FIG. 1).

Die Zwangsführung des Möbelelmentes ( 2 ) mittels der Führungsvorrichtung erfolgt scherenartig.The forced guidance of the furniture element (2) by means of the guiding device takes place like scissors.

Der an der Befestigungsvorrichtung ( 23 ) befestigte feste Drehpunkt ( 12a ) wird nach ( 12b ) gebracht. Somit werden die zwangsgeführten Drehpunkte ( 13 ), ( 21 ) und ( 22 ) entlang des Führungsprofiles ( 14 ) und ( 15 ) geführt. Das Führungsprofile ( 14 ) ist dabei an der Grundplatte ( 1 ) befestigt. Das Führungsprofile ( 15 ) ist am Möbelelement ( 2 ) rückseitig befestigt. Die Koppelglieder ( C ) sind drehbar über das Drehelement ( 16 ) miteinander verbunden. Dadurch wird die scherenartige Führung der Koppelglieder ermöglicht.The fixed pivot point (12a) attached to the fastening device (23) is brought to (12b). Thus the positively guided pivot points (13), (21) and (22) are guided along the guide profile (14) and (15). The guide profile (14) is attached to the base plate (1). The guide profile (15) is attached to the rear of the furniture element (2). The coupling elements (C) are rotatably connected to one another via the rotating element (16). This enables the scissor-like guidance of the coupling links.
