Description

Die Erfindung richtet sich auf eine Vorrichtung zum Koordinieren einer Relativbewegung zwischen einem bewegbaren Möbelteil und einem ortsfesten Möbelteil entlang einer Führungsleiste gemäß dem Oberbegriff von Anspruch 1, wobei die Vorrichtung im bestimmungsgemäßen Zustand an dem einen Möbelteil und die Führungsleiste an dem anderen Möbelteil angeordnet ist. Ferner richtet sich die Erfindung auf ein Möbelstück nach Anspruch 14 mit zumindest einem ortsfesten Möbelteil und einem relativ dazu bewegbaren Möbelteil, die mit einer solchen Vorrichtung und Führungsleiste versehen sind, um die Relativbewegung der Möbelteile zu gewährleisten.The invention is directed to a device for coordinating a relative movement between a movable furniture part and a stationary furniture part along a guide rail according to the preamble of claim 1, wherein the device is arranged in the intended condition on one furniture part and the guide rail on the other furniture part. Furthermore, the invention is directed to a piece of furniture according to claim 14 with at least one stationary furniture part and a relatively movable furniture part, which are provided with such a device and guide bar to ensure the relative movement of the furniture parts.

Vorrichtungen und Möbel bzw. Möbelstücke der eingangs genannten Art sind im Stand der Technik in verschiedenen Ausgestaltungen bekannt. Ein Beispiel stellen Tische und Schränke mit Schubladen dar, wobei die Schubladen eine Relativbewegung zu dem jeweiligen Tisch oder Schrank vollziehen siehe z.B. US 4 441 771 . Ferner sind beispielsweise Betten oder Schlafcouchen, /-sofas mit einem bewegbaren, die Liegefläche bildenden Oberteil und einem ortsfesten, einen Bettkasten aufweisenden Unterteil bekannt, wobei das Oberteil relativ zum Unterteil bewegt werden kann, um den Bettkasten freizulegen oder das Sofa auszuklappen. Zum Koordinieren dieser Relativbewegung zwischen Oberteil und Unterteil des Bettes oder des Sofas können beispielsweise an der Unterseite des Oberteils Rollen vorgesehen werden, die entlang einer an der Oberseite des Unterteils vorgesehenen schienenartigen Führungsleiste bewegbar sind. Aufgrund der Führung der Rollen innerhalb der schienenartigen Führungsleiste wird dabei eine Verschiebung des Oberteils relativ zum Unterteil quer zur Bewegungsrichtung verhindert. Ein Nachteil dieser Ausgestaltung besteht darin, dass die Rollen sehr massiv ausgebildet werden müssen, da diese das Eigengewicht des Oberteils sowie sämtliche Lasten aufnehmen müssen, die auf die Liege- bzw. Sitzfläche des Bettes ausgeübt werden. Sind die Rollen nicht stabil genug, so kann leicht die Lauffähigkeit der Rollen beeinträchtigt werden, so dass ihre Funktionsweise nicht länger gewährleistet ist. Zudem bestehen Rollen aus einer Mehrzahl von Einzelteilen, die montiert werden müssen, was recht zeitintensiv ist. Ferner muss die Führungsleiste als Schiene ausgebildet werden, was ebenfalls nicht wünschenswert ist.Devices and furniture or pieces of furniture of the type mentioned are known in the prior art in various embodiments. An example are tables and cabinets with drawers, where the drawers make a relative movement to the respective table or cabinet see eg U.S. 4,441,771 , Further, for example, beds or sofa beds, / -sofas with a movable, the lying surface forming upper part and a stationary, a bed base having lower part known, the upper part can be moved relative to the lower part to expose the bed box or unfold the sofa. For coordinating this relative movement between the upper part and the lower part of the bed or the sofa, it is possible, for example, to provide rollers on the underside of the upper part, which rollers are movable along a rail-like guide strip provided on the upper side of the lower part. Due to the leadership of the roles within the rail-like guide bar thereby a displacement of the upper part is prevented relative to the lower part transverse to the direction of movement. A disadvantage of this embodiment is that the rollers must be made very solid, since they must absorb the weight of the upper part and all the loads that are exerted on the lying or sitting area of the bed. If the rollers are not stable enough, the runnability of the rollers can be impaired so that their functioning is no longer guaranteed. In addition, there are roles from a number of items that need to be mounted, which is quite time consuming. Furthermore, the guide bar must be formed as a rail, which is also undesirable.

Bei einer anderen Variante sind die Rollen durch Holzklötze ersetzt, die während der Relativbewegung des Oberteils und des Unterteils des Bettes entlang einer schienenartigen Führungsleiste bewegt werden. Bei häufiger Beanspruchung und insbesondere wenn das Oberteil relativ zum Unterteil gekippt wird, um ersteres besser ausziehen zu können, splittern die Holzklötze jedoch leicht, wodurch ihre Funktion beeinträchtigt werden kann. Ferner weisen die Holzklötze scharfe Kanten auf, die auf Dauer die Führungsleiste beschädigen können. Schließlich ist auch bei dieser Variante eine schienenartige Führungsleiste erforderlich, was es nach Möglichkeit zu vermeiden gilt.In another variant, the rollers are replaced by wooden blocks, which are moved during the relative movement of the upper part and the lower part of the bed along a rail-like guide rail. With frequent use, and especially when the upper part is tilted relative to the lower part, in order to be able to extend the former better, the wooden blocks splinter easily, whereby their function can be impaired. Furthermore, the wooden blocks have sharp edges that can permanently damage the guide bar. Finally, even with this variant, a rail-like guide rail is required, which should be avoided if possible.

Ausgehend von diesem Stand der Technik ist es eine Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Koordinieren einer Relativbewegung zwischen einem bewegbaren Möbelteil und einem ortsfesten Möbelteil entlang einer Führungsleiste zu schaffen, die einen einfachen und kostengünstigen Aufbau aufweist und welche eine langlebige und zuverlässige Handhabung ermöglicht.Based on this prior art, it is an object of the present invention to provide a device for coordinating a relative movement between a movable furniture part and a stationary furniture part along a guide bar, which has a simple and inexpensive construction and which allows a durable and reliable handling.

Zur Lösung dieser Aufgabe schafft die vorliegende Erfindung eine Vorrichtung zum Koordinieren einer Relativbewegung zwischen einem bewegbaren Möbelteil und einem ortsfesten Möbelteil nach Anspruch 1, sowie ein Möbelstück nach Anspruch 14. Die abhängigen Ansprüche beziehen sich auf individuelle Ausgestaltungen der vorliegenden Erfindung.To achieve this object, the present invention provides a device for coordinating a relative movement between a movable furniture part and a stationary furniture part according to claim 1, and a piece of furniture according to claim 14. The dependent claims relate to individual embodiments of the present invention.

Die hier vorgeschlagene Vorrichtung, die zum Koordinieren einer Relativbewegung zwischen einem bewegbaren Möbelteil und einem ortsfesten Möbelteil entlang einer Führungsleiste dient, wobei die Vorrichtung in einem bestimmungsgemäßen Zustand an einem Möbelteil und die Führungsleiste an dem anderen Möbelteil angeordnet ist, umfasst eine Auflage- und Gleitfläche, die bei der Relativbewegung auf der Führungsleiste aufliegt und auf dieser gleitend bewegbar ist, eine Führungsfläche, welche die Vorrichtung bei der Relativbewegung entlang der Führungsleiste führt, und eine Anschlagfläche, die bei Erreichen einer vorbestimmten Endposition an einem Bereich des ortsfesten Möbelteils oder der Führungsleiste anschlägt, wobei sich die Auflage- und Gleitfläche, die Führungsfläche und die Anschlagfläche jeweils quer zueinander erstrecken und ebenso umfasst die Auflage- und Gleitfläche einen Hauptflächenbereich, der in einem Normalzustand auf der Führungsleiste aufliegt, und wenigstens einen Nebenflächenbereich, der gegenüber dem Hauptflächenbereich in Bewegungsrichtung des bewegbaren Möbel derart geneigt ist, dass er im Falle eines relativen Kippens der Möbelteile auf der Führungsleiste bevorzugt großflächig zur Auflage kommt. Die Auflage-und Gleitfläche der Vorrichtung dient zum einen als Auflager und nimmt Lasten auf, die auf das Möbelteil ausgeübt werden. Während der Relativbewegung zwischen dem bewegbaren Möbelteil und dem ortsfesten Möbelteil ist sie zum anderen gleitend auf der Führungsleiste bewegbar und dient entsprechend als Gleitfläche. Die Führungsfläche führt die Vorrichtung bei der Relativbewegung der Möbelteile entlang der Führungsleiste, wodurch diese zum einen die Richtung der Relativbewegung, die nachfolgend als Bewegungsrichtung bezeichnet wird, vorgibt und zum anderen eine Relativbewegung in zumindest einer Richtung quer zur Bewegungsrichtung verhindert. Die Anschlagfläche definiert schließlich die Endposition der Relativbewegung.The device proposed here, which is used to coordinate a relative movement between a movable furniture part and a stationary furniture part along a guide rail, wherein the device is arranged in a proper condition on a furniture part and the guide rail on the other furniture part comprises a support and sliding surface, which rests on the guide rail during the relative movement and is slidably movable thereon, a guide surface which guides the device during the relative movement along the guide rail, and a stop surface which strikes a region of the stationary furniture part or the guide rail when a predetermined end position is reached; wherein the support and sliding surface, the guide surface and the stop surface each extend transversely to each other and also includes the support and sliding surface a major surface area which rests in a normal state on the guide rail, and we at least one auxiliary surface area which is inclined relative to the main surface area in the direction of movement of the movable furniture in such a way that, in the case of a relative tilting of the furniture parts on the guide strip, it preferably comes into contact over a large area. The support and sliding surface of the device serves as a support and takes on loads that are exerted on the furniture part. During the relative movement between the movable furniture part and the stationary furniture part, it is on the other hand slidably movable on the guide rail and serves as a sliding surface accordingly. The guide surface leads the device during the relative movement of the furniture parts along the guide bar, whereby this on the one hand, the direction of relative movement, which is hereinafter referred to as the direction of movement, and on the other hand prevents relative movement in at least one direction transverse to the direction of movement. The stop surface finally defines the end position of the relative movement.

Erfindungsgemäß umfasst die Vorrichtung wenigstens ein Durchgangsloch zur Aufnahme eines Befestigungsmittels, wie beispielsweise zur Aufnahme einer Schraube. Vorteilhaft sind jedoch mehr als ein Durchgangsloch vorgesehen, um eine Verdrehung der Vorrichtung im an einem Möbelteil befestigten Zustand zu verhindern.According to the invention, the device comprises at least one through hole for receiving a fastening means, such as for receiving a screw. Advantageously, however, more than one through hole are provided in order to prevent a rotation of the device in the attached state to a furniture part.

Da das bewegbare Möbelteil normalerweise zum Ausführen der Relativbewegung zwischen den Möbelteilen im Bezug auf das ortsfeste Möbelteil - durch geringes Anheben - gekippt wird, da sich der bewegbare Möbelteil auf diese Weise bequemer handhaben lässt, umfasst die Auflage- und Gleitfläche neben dem Hauptflächenbereich, der im Normalzustand auf der Führungsleiste aufliegt, zudem zumindest einen Nebenflächenbereich, der gegenüber dem Hauptflächenbereich in Bewegungsrichtung des bewegbaren Möbelteils derart geneigt ist, dass er im Falle eines relativen Kippens der Möbelteile auf der Führungsleiste bevorzugt großflächig zur Auflage kommt. Entsprechend wird auch im Falle eines Kippens des bewegbaren Möbelteils ein großflächiges Auflager sowie eine Gleitfläche durch die erfindungsgemäße Vorrichtung bereitgestellt. Hierdurch wird einerseits der Abtrieb zwischen der Vorrichtung und korrespondierenden Führungsleiste reduziert und andererseits kann ein Verkanten des bewegbaren Möbelteils bei der auszuführenden Relativbewegung sicher vermieden werden.Since the movable furniture part is usually tilted to carry out the relative movement between the furniture parts with respect to the fixed furniture part - by little lifting - because the movable furniture part can be handled more comfortably in this way, the support and sliding surface next to the main surface area, which in Normal state rests on the guide rail, in addition at least one secondary surface area, which is inclined relative to the main surface area in the direction of movement of the movable furniture part such that it preferably in the case of a relative tilting of the furniture parts on the guide bar over a large area comes to rest. Accordingly, in the case of a tilting of the movable furniture part, a large-area bearing and a sliding surface are provided by the device according to the invention. As a result, on the one hand the output between the device and corresponding guide rail is reduced and on the other hand, tilting of the movable furniture part can be reliably avoided in the relative movement to be performed.

Bevorzugt weist die Auflage- und Gleitfläche zwei Nebenflächenbereiche auf, die an gegenüberliegenden Seiten des Hauptflächenbereiches angeordnet sind. Entsprechend kann die Vorrichtung in verschiedenen Ausrichtungen verwendet werden, was unter Bezugnahme auf die nachfolgend beschriebenen Ausführungsformen der erfindungsgemäßen Vorrichtung noch genauer erläutert wird. Allerdings sei bereits jetzt schon erwähnt, dass somit ein und dieselbe Vorrichtung sowohl linkseitig als auch rechtsseitig zum Koordinieren der Relativbewegung verwendbar ist. Hierdurch lassen sich die Herstellungs- und Lagerkosten durch höhere Stückzahlen reduzieren und die Montage der Vorrichtung an dem Möbelstück vereinfachen. Der bzw. die zuvor genannten Neigungswinkel zwischen dem Hauptflächenbereich und dem bzw. den Nebenflächenbereich(en) liegen bevorzugt im Bereich von 5° bis 30°, besser noch im Bereich von 15° bis 25°.Preferably, the support and sliding surfaces have two auxiliary surface regions, which are arranged on opposite sides of the main surface region. Accordingly, the device can be used in various orientations, which will be explained in more detail with reference to the embodiments of the device according to the invention described below. However, it should already be mentioned that one and the same device can thus be used both on the left side and on the right side for coordinating the relative movement. As a result, the manufacturing and storage costs can be reduced by higher quantities and simplify the installation of the device on the piece of furniture. The aforementioned inclination angle between the main surface area and the minor area area (s) is preferably in the range of 5 ° to 30 °, more preferably in the range of 15 ° to 25 °.

Die Figuren 1 bis 3 zeigen eine erste Ausführungsform einer Vorrichtung 10, zum Koordinieren einer Relativbewegung zwischen einem bewegbaren Möbelteil 44 und einem ortsfesten Möbelteil 46 entlang einer Führungsleiste 50, 52 gemäß der vorliegenden Erfindung, wobei Figur 1 eine perspektivische Ansicht, Figur 2 eine Draufsicht und Figur 3 eine Unteransicht der Vorrichtung 10 darstellt. Die Vorrichtung 10 ist aus einem Kunststoff einteilig mittels Spritzgussverfahren hergestellt, welcher insbesondere technisches Polyurethan (PU), Polypropylen (PP) oder Polyethylen (PE) bzw. Mischungen der zuvor genannten Stoffe aufweist. Die Vorrichtung 10 umfasst einen Auflage-, Anschlag- und Gleitabschnitt 12 sowie einen Führungs- und Anschlagabschnitt 14, die nebeneinander angeordnet sind und sich rechtwinklig zueinander erstrecken. Der Auflage-, Anschlag- und Gleitabschnitt 12 weist an seiner Oberseite eine Auflage- und Gleitfläche 16 auf, die in drei Bereiche unterteilt ist, nämlich in einen Hauptflächenbereich 18 und in zwei Nebenflächenbereiche 20, 22. Die beiden Nebenflächenbereiche 20, 22 sind an gegenüberliegenden Seiten des Hauptflächenbereiches 18 angeordnet und gegenüber dem Hauptflächenbereich 18 zur Bewegungsrichtung B, in der die Vorrichtung 10 im bestimmungsgemäßen Zustand bewegt wird (siehe Figur 6), in einem Winkel α abwärts geneigt. Der Winkel α liegt bevorzugt in einem Bereich von 5° bis 30°, besser noch 15° bis 25°. In der Mitte der Auflage- und Gleitfläche 16 ist ein Durchgangsloch 24 zu Aufnahme einer Schraube vorgesehen. Das Durchgangsloch 24 setzt sich an der Unterseite der Auflage- und Gleitfläche 16 in einer röhrenartigen Ausbildung 26 fort, die durch Stege 28 stabilisiert ist, wobei die Stege 28 zwei Aussparungen 30 an der Unterseite des Auflage-, Anschlag- und Gleitabschnitts voneinander trennen. Alternativ kann der Auflage-, Anschlag- und Gleitabschnitt 12 auch als Vollkörper mit darin vorgesehenem Durchgangsloch 24 ausgebildet werden. Die in den Figuren 1-3 dargestellte Ausgestaltung des Auflage-, Anschlag- und Gleitabschnittes 12 mit den Aussparungen 30, der röhrenartigen Ausbildung 26 und den Stegen 28 ist jedoch hinsichtlich der Material- und Gewichtsreduzierung vorteilhaft.The FIGS. 1 to 3 show a first embodiment of a device 10, for coordinating a relative movement between a movable furniture part 44 and a stationary furniture part 46 along a guide rail 50, 52 according to the present invention, wherein FIG. 1 a perspective view, FIG. 2 a top view and FIG. 3 a bottom view of the device 10 represents. The device 10 is made of a plastic in one piece by means of injection molding, which in particular technical polyurethane (PU), polypropylene (PP) or polyethylene (PE) or mixtures of the aforementioned substances. The device 10 comprises a support, stop and sliding portion 12 and a guide and stop portion 14, which are arranged side by side and extend at right angles to each other. The support, abutment and sliding portion 12 has on its upper side on a support and sliding surface 16 which is divided into three areas, namely in a main surface area 18 and in two auxiliary surface areas 20, 22. The two auxiliary surface areas 20, 22 are at opposite Side of the main surface area 18 and arranged opposite the main surface area 18 to the direction of movement B, in which the device 10 is moved in the intended condition (see FIG. 6 ), inclined downwards at an angle α. The angle α is preferably in a range of 5 ° to 30 °, more preferably 15 ° to 25 °. In the middle of the support and sliding surface 16, a through hole 24 is provided for receiving a screw. The through hole 24 continues on the underside of the support and sliding surface 16 in a tubular formation 26 which is stabilized by webs 28, wherein the webs 28, two recesses 30 on the underside of the support, stop and sliding section from each other. Alternatively, the support, abutment and sliding portion 12 can be formed as a solid body with through hole 24 provided therein. The in the Figures 1-3 illustrated embodiment of the support, stop and sliding portion 12 with the recesses 30, the tubular formation 26 and the webs 28, however, is advantageous in terms of material and weight reduction.

Der Führungsabschnitt 14 ist im Wesentlichen quaderförmig ausgebildet und weist an seiner Oberseite 32 ein Durchgangsloch 34 auf. Ähnlich wie das Durchgangsloch 24 des Auflage-, Anschlag- und Gleitabschnitts 12 setzt sich auch das Durchgangsloch 34 an der Unterseite der Oberseite 32 in Form einer röhrenartigen Ausbildung 36 fort, die durch Stege 38 innerhalb einer Aussparung 40 gestützt ist. Alternativ kann der Führungsabschnitt 14 ebenso wie der Auflage-, Anschlag- und Gleitabschnitt 12 als Vollkörper mit darin ausgebildetem Durchgangsloch 34 ausgebildet werden, wobei jedoch die in den Figuren 1 bis 3 dargestellte Ausgestaltung mit der Aussparung 40, der röhrenartigen Ausbildung 36 und den Stegen 38 hinsichtlich einer Gewichts- und Materialreduzierung vorteilhaft ist.The guide section 14 has a substantially cuboid shape and has a through hole 34 on its upper side 32. Similar to the through hole 24 of the support, abutment and sliding portion 12, the through hole 34 on the underside of the top surface 32 continues in the form of a tubular formation 36 which is supported by webs 38 within a recess 40. Alternatively, the guide portion 14 as well as the support, abutment and sliding portion 12 may be formed as a solid body having formed therein through hole 34, wherein, however, in the FIGS. 1 to 3 illustrated embodiment with the recess 40, the tubular formation 36 and the webs 38 is advantageous in terms of weight and material reduction.

Beide Durchgangslöcher 24, 34 sind gesenkt, so dass der jeweilige Schraubenkopf der in den Durchgangslöchern 24, 34 aufzunehmenden Schrauben nicht über den Hauptflächenbereich 18 der Auflage- und Gleitfläche 16 bzw. nicht über die Oberseite 32 des Führungs- und Anschlagabschnittes 14 vorsteht.Both through holes 24, 34 are lowered, so that the respective screw head of the screws to be received in the through holes 24, 34 does not project beyond the main surface region 18 of the support and sliding surface 16 or not over the upper surface 32 of the guide and stop section 14.

Die Figuren 4 und 5 sind perspektivische Ansichten und zeigen ein Möbelstück 42 in Form einer Schlafcouch bzw. Schlafsofa mit einem bewegbaren oberen Möbelteil 44 und einem ortsfesten unteren Möbelteil 46, wobei Figur 5 das Möbel 42 im ausgezogenen Zustand und Figur 4 das Möbel 42 im nicht-ausgezogenen Zustand zeigt. Das obere Möbelteil 44 bildet eine Liegefläche der Schlafcouch, wohingegen das untere Möbelteil 46 einen Bettkasten 48 aufweist. Um den Bettkasten 48 aus dem in Figur 4 dargestellten nicht-ausgezogenen Zustand freizulegen, wird das obere Möbelteil 44 relativ zu dem unteren Möbelteil 46 in Bewegungsrichtung B nach vorne ausgezogen, wie es in Figur 5 dargestellt ist. Dabei bewegt sich je eine Vorrichtung 10 der in den Figuren 1 bis 3 dargestellten Art entlang einer der an dem unteren Möbelteil 46 angeordneten Führungsleisten 50, 52, welches in Figur 6 dargestellt ist und nachfolgend genauer erläutert wird.The FIGS. 4 and 5 are perspective views and show a piece of furniture 42 in the form of a sofa bed or sofa bed with a movable upper furniture part 44 and a stationary lower furniture part 46, wherein FIG. 5 the furniture 42 in the extended state and FIG. 4 the furniture 42 in the non-extended state shows. The upper furniture part 44 forms a lying surface of the sofa bed, whereas the lower furniture part 46 a Bed box 48 has. To the bed box 48 from the in FIG. 4 uncovered illustrated non-extended state, the upper furniture part 44 is pulled out relative to the lower furniture part 46 in the direction of movement B to the front, as shown in FIG. 5 is shown. In this case, each moves a device 10 in the FIGS. 1 to 3 shown along one of the arranged on the lower furniture part 46 guide rails 50, 52, which in FIG. 6 is shown and explained in more detail below.

Figur 6 ist eine perspektivische Ansicht und zeigt eine Vorrichtung 10 gemäß den Figuren 1 bis 3, die an der Führungsleiste 50 des in den Figuren 4 und 5 dargestellten Möbels 42 angeordnet ist. FIG. 6 is a perspective view showing a device 10 according to the FIGS. 1 to 3 attached to the guide rail 50 of the FIGS. 4 and 5 shown furniture 42 is arranged.

Die Vorrichtung 10 ist mit Hilfe von durch die Durchgangslöcher 24, 34 der Vorrichtung 10 hindurch geführte Schrauben 54 an der Unterseite des oberen Möbelteils 44 befestigt, wobei in Figur 6 auf die Darstellung des oberen Möbelteils 44 verzichtet wurde. Die Vorrichtung 10 ist derart an der Führungsleiste 50 positioniert, dass der Hauptflächenbereich 18 der Auflage- und Gleitfläche 16 des Auflage-, Anschlag- und Gleitabschnitts 12 auf der Oberseite der Führungsleiste 50 aufliegt. Entsprechend dient der Hauptflächenbereich 18 der Auflage- und Gleitfläche 16 als Auflager zur Aufnahme des Eigengewichts des oberen Möbelteils 44 sowie von Kräften, die auf das obere Möbelteil 44 wirken. Wird die Vorrichtung 10 ferner in Bewegungsrichtung B bewegt, so gleitet der Hauptflächenbereich 18 über die Oberseite der Führungsleiste 50.The device 10 is secured by means of guided through the through holes 24, 34 of the device 10 through screws 54 on the underside of the upper furniture part 44, wherein in FIG. 6 has been dispensed with the representation of the upper furniture part 44. The device 10 is positioned on the guide rail 50 in such a way that the main surface region 18 of the support and sliding surface 16 of the support, abutment and sliding section 12 rests on the upper side of the guide rail 50. Accordingly, the main surface area 18 of the support and sliding surface 16 serves as a support for receiving the dead weight of the upper furniture part 44 and of forces acting on the upper furniture part 44. If the device 10 is further moved in the direction of movement B, then the main surface area 18 slides over the top of the guide bar 50th

Die dem Auflage-, Anschlag- und Gleitabschnitt 12 zugewandte Fläche 56 liegt an der Stirnseite der Führungsleiste 50 an und dient während einer Bewegung der Vorrichtung 10 entlang der Führungsleiste 50 als Führung, weshalb diese Fläche nachfolgend als Führungsfläche 56 bezeichnet wird. Ferner verhindert die Führungsfläche 56 unter Bezugnahme auf Fig. 6 eine Bewegung des oberen Möbelteils 44 und der Vorrichtung 10 quer zur Bewegungsrichtung B in Querrichtung C. Die der vorderen Wand 58 des unteren Möbelteils 46 zugewandte Fläche 60 des Auflage-, Anschlag- und Gleitabschnittes 12 schlägt, wenn die Vorrichtung 10 entlang der Führungsleiste 50 in Richtung der vorderen Wand 58 des unteren Möbelteils 46 bewegt wird, irgendwann gegen die vordere Wand 58 an, weshalb diese Fläche 60 nachfolgend als Anschlagfläche 60 bezeichnet wird. Dabei definiert die Anschlagfläche 60 eine Endposition der Relativbewegung zwischen dem oberen Möbelteil 44 und dem unteren Möbelteil 46. Alternativ oder zusätzlich können auch die in Fig. 1 und 2 dargestellten Anschlagsflächen 60, die parallel zu zuvor erwähnten Anschlagsfläche 60 ausgerichtet sind und am Führungsabschnitt 14 angeordnet sind, die Anschlagsfunktion übernehmen.The support, stop and sliding portion 12 facing surface 56 abuts the end face of the guide bar 50 and is used during a movement of the device 10 along the guide bar 50 as a guide, which is why this area is hereinafter referred to as guide surface 56. Further, the guide surface 56 prevents with reference to Fig. 6 a movement of the upper furniture part 44 and the device 10 transversely to the direction of movement B in the transverse direction C. The front wall 58 of the lower furniture part 46 facing surface 60 of the support, abutment and sliding portion 12 strikes when the device 10 along the guide bar 50 in Direction of the front wall 58 of the lower furniture part 46 is moved, at some point against the front wall 58th why this surface 60 is referred to below as a stop surface 60. In this case, the stop surface 60 defines an end position of the relative movement between the upper furniture part 44 and the lower furniture part 46. Alternatively or additionally, the in Fig. 1 and 2 illustrated abutment surfaces 60 which are aligned parallel to the aforementioned abutment surface 60 and are arranged on the guide portion 14, take over the stop function.

Der im Winkel α geneigte Nebenflächenbereich 20 der Auflage- und Gleitfläche 16 kommt an der Oberseite der Führungsleiste 50 zur Auflage, wenn das obere Möbelteil 44 zusammen mit der Vorrichtung 20 relativ zu dem unteren Möbelteil 46 in Richtung des Pfeils 62 gekippt wird. In diesem Zustand dient dann der Nebenflächenbereich 20 als Auflager zur Aufnahme des Eigengewichts des oberen Möbelteils 44. Wird dann eine Relativbewegung zwischen dem oberen Möbelteil 44 und dem unteren Möbelteil 46 in Bewegungsrichtung B ausgeführt, gleitet der Nebenflächenbereich 20 auf der Oberseite der Führungsleiste 50. Das obere Möbelteil 44 ist dank des Nebenflächenbereiches 20 also auch im gekippten Zustand problemlos auf der Führungsleiste 50 gehalten und bewegbar.The inclined at an angle α side surface area 20 of the support and sliding surface 16 comes to rest on the top of the guide bar 50 when the upper furniture part 44 is tilted together with the device 20 relative to the lower furniture part 46 in the direction of arrow 62. If then a relative movement between the upper furniture part 44 and the lower furniture part 46 is executed in the direction of movement B, the auxiliary surface area 20 slides on the top of the guide bar 50th Das Upper furniture part 44 is thus easily held on the guide rail 50 and movable even in the tilted state thanks to the auxiliary surface area 20.

Die Anordnung der Vorrichtung 10 an der in Figur 5 dargestellten Führungsleiste 52 des unteren Möbelteils 46 entspricht der in Figur 6 dargestellten Anordnung mit Ausnahme der Tatsache, dass die baugleiche Vorrichtung 10 um 180° in Richtung des Pfeils 64 gedreht ist. Folglich unterscheiden sich die links- und rechtsseitig angeordneten Vorrichtungen 10, die mit den Führungsleisten 50 bzw. 52 zusammenwirken, nur durch ihre unterschiedlich Anordnung bzw. Ausrichtung. Entsprechend wird durch den Führungsabschnitt 14 der an der Führungsleiste 52 angeordneten Vorrichtung 10 eine Bewegung in der der Querrichtung C entgegengesetzten Richtung verhindert. Somit können das obere Möbelteil 44 und das untere Möbelteil 46 im Wesentlichen nur in Bewegungsrichtung B relativ zueinander bewegt werden.The arrangement of the device 10 at the in FIG. 5 shown guide rail 52 of the lower furniture part 46 corresponds to the in FIG. 6 arrangement shown except for the fact that the identical device 10 is rotated by 180 ° in the direction of arrow 64. Consequently, the left and right side arranged devices 10, which cooperate with the guide rails 50 and 52, respectively, differ only by their different arrangement or orientation. Accordingly, by the guide portion 14 of the arranged on the guide rail 52 device 10 prevents movement in the transverse direction C opposite direction. Thus, the upper furniture part 44 and the lower furniture part 46 can be moved substantially only in the direction of movement B relative to each other.

Figur 7 ist eine perspektivische Ansicht einer zweiten Ausführungsform einer Vorrichtung 70 gemäß der vorliegenden Erfindung. Der Aufbau der Vorrichtung 70 entspricht in wesentlichen Zügen demjenigen der in den Figuren 1 bis 3 dargestellten Vorrichtung 10. Jedoch sind bei der Vorrichtung 70 die Nebenflächenbereiche 20 der Auflage- und Gleitfläche 16 größer als diejenigen der Vorrichtung 10 ausgebildet. Zudem erstreckt sich der Führungsabschnitt 14 über die gesamte Länge des Auflage-, Anschlag-und Gleitabschnitts 12. Entsprechend dient vorliegend die Stirnfläche 72 des Führungsabschnittes 14 ebenfalls als Anschlagfläche, wodurch eine stabilere Anschlagfläche erzielt wird. FIG. 7 is a perspective view of a second embodiment of a device 70 according to the present invention. The structure of the device 70 substantially corresponds to that of those in the FIGS. 1 to 3 shown Device 10. However, in the device 70, the minor surface areas 20 of the bearing and sliding surfaces 16 are made larger than those of the device 10. In addition, the guide portion 14 extends over the entire length of the support, stop and sliding portion 12. Accordingly, in the present case, the end face 72 of the guide portion 14 also serves as a stop surface, whereby a more stable stop surface is achieved.

Figur 8 ist eine perspektivische Ansicht und zeigt eine dritte Ausführungsform einer Vorrichtung 80 gemäß der vorliegenden Erfindung. Der Aufbau der Vorrichtung 80 entspricht in wesentlichen Zügen demjenigen der in den Figuren 1 bis 3 dargestellten Vorrichtung 10 mit Ausnahme der Tatsache, dass zwei Führungsabschnitte 14 vorgesehen sind, die einander gegenüber angeordnet sind. Eine einzelne Vorrichtung 80 verhindert also bereits eine Bewegung des oberen Möbelteils 44 relativ zum unteren Möbelteil 46 quer zur Bewegungsrichtung B. Bei allen in den Figuren dargestellten Vorrichtungen 10, 70 und 80 sind diejenigen Kanten und Ecken, die mit den Führungsleisten 50, 52 oder mit anderen Teilen des Möbels 42 in Kontakt kommen, bevorzugt abgerundet oder angephast ausgebildet, um Beschädigungen sowohl der Vorrichtungen 10, 70 und 80 als auch des Möbels 42 zu verhindern. Ferner sind die Vorrichtungen 10, 70 und 80 bevorzugt einteilig aus einem verschleiß- und reibungsarmen Kunststoff hergestellt. Alternativ können die Vorrichtungen 10, 70 und 80 natürlich auch mehrteilig ausgebildet sein. Ferner können diejenigen Flächen der Vorrichtungen 10, 70 und 80, die mit anderen Bauteilen in Berührung kommen, auch lediglich mit einem reibungs- und verschleißarmen Material beschichtet sein. Auch könnte die Vorrichtung aus einem Sintermaterial aufgebaut sein, bei welchem Schmierstoffe eingebunden sind. FIG. 8 FIG. 12 is a perspective view showing a third embodiment of a device 80 according to the present invention. FIG. The structure of the device 80 substantially corresponds to that in the FIGS. 1 to 3 shown device 10 except for the fact that two guide portions 14 are provided, which are arranged opposite to each other. A single device 80 thus already prevents movement of the upper furniture part 44 relative to the lower furniture part 46 transversely to the direction B. For all devices 10, 70 and 80 shown in the figures, those edges and corners, with the guide rails 50, 52 or with other parts of the furniture 42 come into contact, preferably rounded or bevelled trained to prevent damage to both the devices 10, 70 and 80 and the furniture 42. Furthermore, the devices 10, 70 and 80 are preferably made in one piece from a low-wear and low-friction plastic. Alternatively, the devices 10, 70 and 80 can of course also be designed in several parts. Furthermore, those surfaces of the devices 10, 70 and 80 which come into contact with other components may also be coated with only a low-friction and low-wear material. Also, the device could be constructed of a sintered material, in which lubricants are involved.

Es sollte klar sein, dass die zuvor beschriebenen Ausführungsformen nur als Beispiel dienen und in keiner Weise einschränkend sind. Vielmehr sind Modifikationen und Änderungen möglich, ohne den Schutzbereich der vorliegenden Erfindung zu verlassen, der durch die beiliegenden Ansprüche definiert ist. So ist es auch denkbar, dass die erfindungsgemäße Vorrichtung 10 auch um gedreht (insbesondere um 90° gedreht) oder spiegelsymmetrisch eingebaut werden kann, um die vorgesehene Relativbewegung zwischen den jeweiligen Möbelteilen 44 und 46 zu koordinieren.It should be understood that the embodiments described above are by way of example only and are in no way limiting. Rather, modifications and changes are possible without departing from the scope of the present invention, which is defined by the appended claims. Thus, it is also conceivable that the device 10 according to the invention can also be installed rotated (in particular rotated by 90 °) or mirror-symmetrically in order to coordinate the intended relative movement between the respective furniture parts 44 and 46.
