Description

Die Erfindung betrifft ein System zum Befestigen eines Möbelbeins an einem Möbel und Verfahren zum Befestigen des Möbelbeins an dem Möbel, insbesondere ein System zum Befestigen eines Möbelbeins an einem Möbel und Verfahren zum Befestigen des Möbelbeins an dem Möbel, die eine einfache Montage ermöglichen.The invention relates to a system for attaching a furniture leg to a furniture and methods for attaching the furniture leg to the furniture, in particular a system for attaching a furniture leg to a furniture and methods for attaching the furniture leg to the furniture, which enable easy assembly.

Möbel weisen in der Regel mehrere Komponenten auf. Ein Tisch beispielsweise besteht aus einem Rahmenelement, an dem auf der einen Seite eine Tischplatte und auf der anderen Seite Tisch- bzw. Möbelbeine befestigt sind.Furniture usually has several components. A table, for example, consists of a frame element to which a table top is attached on one side and table or furniture legs on the other side.

Wenn ein Kunde ein solches Möbel käuflich erwirbt, muss dieses vom Hersteller, vom Großhändler, oder vom Einzelhändler zum Kunden transportiert werden. Zum platzsparenden Transport wird das Möbel dabei in seine Einzelteilen zerlegt transportiert. Beim Endkunden müssen dann beispielsweise die einzelnen Möbelbeine ans Möbel montiert werden.If a customer purchases such furniture, it must be transported from the manufacturer, wholesaler or retailer to the customer. To save space, the furniture is transported disassembled into its individual parts. For the end customer, for example, the individual furniture legs then have to be mounted on the furniture.

Aus dem Stand der Technik sind Konstruktionen bekannt, durch welche ein Möbelbein an einem Möbel ohne Zuhilfenahme von Werkzeug angebracht werden kann, beispielsweise mittels einer Einrastvorrichtung. Allerdings haben solche Konstruktionen gemäß dem Stand der Technik den Nachteil, dass die so an einem Möbel angebrachten Möbelbeine nicht spielfrei befestigt sind. Daraus resultiert eine Schwingungsanfälligkeit des Möbels.Constructions are known from the prior art through which a furniture leg can be attached to a piece of furniture without the aid of tools, for example by means of a snap-in device. However, such constructions according to the prior art have the disadvantage that the furniture legs attached to a piece of furniture are not fastened without play. This results in the furniture being susceptible to vibration.

Laut den "Anforderungen und Prüfungen von Büromöbeln - Leitfaden für die Sicherheitsanforderungen an Büro-Arbeitstische und Büroschränke in Deutschland" (siehe DIN-Fachbericht 147, Juni 2006, Punkt 3.6) des DIN-Instituts (Deutsches Institut für Normung e.V.) muss durch die Konstruktion eines Büro-Arbeitstisches allerdings sichergestellt sein, dass Schwingungen verhindert werden. Hierfür ist ein spezieller Test mittels eines Pendelschlaghammers vorgesehen. Konstruktionen gemäß dem Stand der Technik, welche das Befestigen eines Möbelbeins an einem Möbel ohne die Zuhilfenahme von Werkzeug vorsehen, erfüllen die Kriterien des DIN-Instituts bezüglich der Schwingungsfreiheit in der Regel nicht.According to the "Requirements and tests of office furniture - Guide for the safety requirements for office work tables and office cabinets in Germany" (see DIN technical report 147, June 2006, point 3.6) of the DIN Institute (German Institute for Standardization eV), however, the design of an office work table must ensure that vibrations are prevented. A special test using a pendulum impact hammer is intended for this purpose. Constructions according to the state of the art, which provide for the attachment of a furniture leg to a piece of furniture without the use of tools, generally do not meet the DIN Institute's criteria regarding freedom from vibration.

Aus dem Stand der Technik-Dokument DE 10 2005 037 394 A1 ist ein solches Standfußbefestigungssystem bekannt, in welchem ein Verriegelungsmechanismus zum werkzeuglosen Verriegeln eines Tischbeins an einem Tisch offenbart wird. Bei der offenbarten Konstruktion wird das Tischbein schräg in eine Ausnehmung des Tisches eingesetzt, und durch ein Kippen (bzw. Aufrichten) des Tischbeins ein Verriegeln durch ein Verriegelungselement ausgelöst. Bei dieser Konstruktion wird in der Regel keine spielfreie Festlegung des Tischbeins innerhalb der Ausnehmung erreicht werden, es sei denn, die Abmessungen der zu verriegelnden Teile, also Ausnehmung und Kopfstück, sind als Presspassung ausgeführt, was sehr aufwändig und extrem teuer in der Herstellung wäre. Zudem wäre die Montage nur mit extrem großen Kraftaufwand möglich, da man die Bauteile bei einer Presspassung mit hoher Kraft einpressen muss, damit sie sicher gehalten werden können.From the prior art document DE 10 2005 037 394 A1 Such a base fastening system is known, in which a locking mechanism for locking a table leg to a table without tools is disclosed. In the disclosed construction, the table leg is inserted obliquely into a recess in the table, and when the table leg is tilted (or raised), locking is triggered by a locking element. With this construction, the table leg will generally not be fixed within the recess without play, unless the dimensions of the parts to be locked, i.e. recess and head piece, are designed as a press fit, which would be very complex and extremely expensive to produce. In addition, assembly would only be possible with an extremely large amount of force, as the components have to be pressed in with great force for a press fit so that they can be held securely.

Es ist daher Aufgabe der vorliegenden Erfindung, ein System zum Befestigen eines Möbelbeins an einem Möbel bereitzustellen, mit welchem ein Möbelbein schnell, einfach, kostengünstig und spielfrei, zudem ohne Zuhilfenahme von Werkzeug an einem Möbel befestigt werden kann.It is therefore the object of the present invention to provide a system for attaching a furniture leg to a piece of furniture, with which a furniture leg can be attached to a piece of furniture quickly, easily, inexpensively and without play, and without the use of tools.

Die Aufgabe wird durch ein System gemäß Anspruch 1 und ein Verfahren gemäß Anspruch 12 gelöst. Vorteilhafte Weiterentwicklungen der Erfindung sind in den abhängigen Ansprüchen enthalten.The task is solved by a system according to claim 1 and a method according to claim 12. Advantageous further developments of the invention are contained in the dependent claims.

Gemäß einem Aspekt der Erfindung weist ein System zum Befestigen eines Möbelbeins an einem Möbel ein Befestigungselement, das dazu eingerichtet ist, an dem Möbelbein befestigbar zu sein, und ein Halteelement, das dazu eingerichtet ist, an dem Möbel befestigbar zu sein, auf. Das Halteelement weist an einer Seite einen ersten Vorsprung und einen von dem ersten Vorsprung beabstandeten zweiten Vorsprung auf. Das Befestigungselement weist eine erste Seite, eine an der ersten Seite angrenzende zweite Seite und eine der ersten Seite gegenüberliegende dritte Seite auf. Ferner weist das Befestigungselement eine zur ersten Seite hin offene Aussparung, die dazu eingerichtet ist, den ersten Vorsprung aufzunehmen, eine von der zweiten Seite ausgehend an der dritten Seite entlang verlaufende Vorspannfläche und eine sich an die Vorspannfläche anschließende von der dritten Seite abstehende Anschlagfläche auf.According to one aspect of the invention, a system for attaching a furniture leg to a piece of furniture includes a fastening element adapted to be attachable to the furniture leg and a retaining element adapted to be attachable to the furniture. The holding element has one on one side first projection and a second projection spaced apart from the first projection. The fastening element has a first side, a second side adjacent to the first side and a third side opposite the first side. Furthermore, the fastening element has a recess that is open towards the first side and is designed to accommodate the first projection, a pretensioning surface that extends from the second side along the third side, and a stop surface that adjoins the pretensioning surface and projects from the third side.

Das Halteelement mit dem ersten Vorsprung und dem zweiten Vorsprung, und das Befestigungselement mit der Aussparung, der Vorspannfläche und der Anschlagfläche sind dazu eingerichtet, dass das System in einem Zustand, in dem der erste Vorsprung von der ersten Seite aus in einer vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung anliegt und der zweite Vorsprung spielfrei an der Vorspannfläche und an der Anschlagfläche anliegt, eine spielfreie Befestigung des Möbelbeins am Möbel ermöglicht.The holding element with the first projection and the second projection, and the fastening element with the recess, the biasing surface and the stop surface are designed to ensure that the system is in a state in which the first projection extends from the first side at a predetermined depth and thereby rests against the recess without play on both sides and the second projection rests against the pretensioning surface and on the stop surface without play, allowing the furniture leg to be attached to the furniture without play.

Durch eine solche Konfiguration des Systems ist es mit einfachen und kostengünstigen Mitteln möglich, das Möbelbein einfach und spielfrei an das Möbel zu montieren.By configuring the system in this way, it is possible to mount the furniture leg on the furniture easily and without play using simple and inexpensive means.

In einer vorteilhaften Weiterbildung des Systems ist der erste Vorsprung durch eine erste Achse ausgebildet und der zweite Vorsprung ist durch eine zweite Achse ausgebildet, die jeweils von dem Halteelement vorstehen.In an advantageous development of the system, the first projection is formed by a first axis and the second projection is formed by a second axis, each of which protrudes from the holding element.

Achsen sind einfach und kostengünstig zu beschaffen oder anzufertigen und zu lagern, so dass eine kostengünstige Herstellung unterstützt wird.Axles are easy and inexpensive to obtain or manufacture and store, supporting cost-effective manufacturing.

Gemäß einer weiteren vorteilhaften Weiterbildung des Systems sind die erste Achse und die zweite Achse zwischen gegenüberliegenden Seiten von dem Halteelement vorstehend angeordnet, und das Befestigungselement weist zwei Aussparungen, die jeweils dazu eingerichtet sind, die erste Achse aufzunehmen, und zwei Vorspannflächen und zwei Anschlagflächen, an denen jeweils die zweite Achse anliegt, auf.According to a further advantageous development of the system, the first axis and the second axis are arranged protruding between opposite sides of the holding element, and the fastening element has two recesses, each of which is designed to receive the first axis, and two Preloading surfaces and two stop surfaces, against which the second axis rests.

Durch das Vorsehen der ersten und zweiten Achsen an gegenüberliegenden Seiten, wobei die Seiten voneinander abgewandt oder einander zugewandt sein können, wird eine Stabilität des Systems erhöht und eine Lage des Möbelbeins zu dem Möbel kann einfach festgelegt werden.By providing the first and second axes on opposite sides, whereby the sides can face away from or facing each other, stability of the system is increased and a position of the furniture leg in relation to the furniture can be easily determined.

einer weiteren vorteilhaften Weiterbildung des Systems weist das Halteelement Öffnungen zum Aufnehmen der Achsen auf, und zumindest eine der Öffnungen weist einen Querschnitt auf, der dazu eingerichtet ist, dass ein kraftfreies Einführen einer von der ersten und zweiten Achse in die zumindest eine Öffnung ermöglicht wird, und dass, in dem Zustand, in dem die erste Achse von der ersten Seite aus in der vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung anliegt und die zweite Achse spielfrei an der Vorspannfläche und an der Anschlagfläche anliegt, die zumindest eine von der ersten und zweiten Achse und die zumindest eine der Öffnungen zwei Kontaktpunkte aufweisen.In a further advantageous development of the system, the holding element has openings for receiving the axes, and at least one of the openings has a cross section which is designed to enable force-free insertion of one of the first and second axes into the at least one opening, and that, in the state in which the first axis rests against the recess from the first side at the predetermined depth and with no play on both sides and the second axis rests against the preload surface and the stop surface without play, the at least one of the first and second axis and the at least one of the openings have two contact points.

Durch den Querschnitt, der das kraftfreie Einführen ermöglicht, also beispielsweise ein freier Querschnitt, der größer als ein Durchmesser der Achse ist, kann die Achse einfach und schnell an dem Halteelement montiert werden. In der Position, in der der erste Vorsprung von der ersten Seite aus in der vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung anliegt, und der zweite Vorsprung spielfrei an der Vorspannfläche und an der Anschlagfläche anliegt, also in der montierten Position, ist durch die zwei Kontaktpunkte eine absolut spielfreie und statisch bestimmte Fixierung möglich.Due to the cross section that enables force-free insertion, for example a free cross section that is larger than a diameter of the axle, the axle can be easily and quickly mounted on the holding element. In the position in which the first projection rests against the recess from the first side at the predetermined depth and with no play on both sides, and the second projection rests against the preload surface and the stop surface without play, i.e. in the mounted position, is through the Two contact points ensure absolutely play-free and statically determined fixation.

Bei einer vorteilhaften Weiterbildung des Systems weist zumindest eine Öffnung einen ovalen Querschnitt auf.In an advantageous development of the system, at least one opening has an oval cross section.

Ein ovaler Querschnitt für das Ermöglichen bzw. Bereitstellen der zwei Kontaktpunkte ist einfach und kostengünstig herzustellen.An oval cross section for enabling or providing the two contact points is easy and inexpensive to produce.

In einer nächsten vorteilhaften Weiterbildung des Systems ist das Befestigungselement dazu eingerichtet, dass ein Abstand zwischen einer Mittelachse der ersten Achse und der Vorspannfläche entlang dem Verlauf der Vorspannfläche von der zweiten Seite zu der Anschlagfläche nicht konstant ist, wobei die erste Achse in der vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung anliegt.In a next advantageous development of the system, the fastening element is set up so that a distance between a central axis of the first axis and the preload surface is not constant along the course of the preload surface from the second side to the stop surface, the first axis being at the predetermined depth and there is no play on both sides of the recess.

Durch den nicht konstanten Abstand wird es ermöglicht, dass eine Spielfreiheit des Systems in der Position, in der die zweite Achse an der Anschlagfläche und spielfrei an der Vorspannfläche anliegt, einfach zu erreichen ist, oder dass in dieser eine Vorspannkraft zwischen den Vorsprüngen, der Aussparung und der Vorspannfläche einfach in einer gewünschten Weise erzeugt wird, indem der Abstand entsprechend im Voraus abgestimmt wird.The non-constant distance makes it possible to easily achieve freedom from play in the system in the position in which the second axis rests against the stop surface and against the pretensioning surface without play, or that in this position there is a pretensioning force between the projections, the recess and the biasing surface is easily created in a desired manner by adjusting the distance accordingly in advance.

Bei einer nächsten vorteilhaften Weiterbildung des Systems weist die Vorspannfläche einen ersten Bereich, entlang dem sich der Abstand von der zweiten Seite ausgehend vergrößert, und einen sich an den ersten Bereich anschließenden zweiten Bereich, entlang dem sich der Abstand von dem zweiten Bereich ausgehend verkleinert oder konstant bleibt, auf.In a next advantageous development of the system, the biasing surface has a first area along which the distance from the second side increases, and a second area adjoining the first area, along which the distance from the second area decreases or remains constant stays, on.

Durch das Vorsehen dieser zwei Bereiche kann das Verhalten des Befestigungselements zu dem Halteelement während der Montage beeinflusst werden. Da sich der Abstand in dem ersten Bereich vergrößert, wird bei einer Bewegung der Achse entlang der Vorspannfläche entweder allmählich eine Spielfreiheit erzeugt oder die Vorspannkraft wird kontrolliert aufgebracht. In dem zweiten Bereich kann dann die Spielfreiheit oder die Vorspannkraft einfach erhalten bleiben, da keine Kraftkomponente so wirkt, dass die Verbindung gelöst wird.By providing these two areas, the behavior of the fastening element to the holding element can be influenced during assembly. Since the distance in the first area increases, when the axis moves along the preload surface, either a clearance is gradually created or the preload force is applied in a controlled manner. In the second area, the freedom from play or the preload force can then simply be maintained, since no force component acts in such a way that the connection is released.

Darüber hinaus kann ein Übergang von dem ersten in den zweiten Bereich taktil durch einen Monteur erfasst werden, so dass ein Erreichen der endgültigen Position durch den Monteur spürbar erfassbar ist.In addition, a transition from the first to the second area can be detected tactilely by a fitter, so that the fitter can noticeably detect when the final position has been reached.

In einer weiteren vorteilhaften Weiterbildung des Systems weist die Aussparung eine Abmessung in Richtung zu der zweiten Seite auf, die sich von der ersten Seite ausgehend zu der dritten Seite hin verkleinert.In a further advantageous development of the system, the recess has a dimension towards the second side, which decreases from the first side towards the third side.

Eine solche Form der Aussparung ist einfach herzustellen und dabei kann durch eine Abstimmung mit dem Durchmesser der Achse die Position der ersten Achse in der sie von der ersten Seite aus in der vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung anliegt, einfach bestimmt werden.Such a shape of the recess is easy to produce and the position of the first axis in which it rests on the recess from the first side at the predetermined depth and with no play on both sides can be easily determined by coordinating with the diameter of the axis.

Gemäß einer anderen vorteilhaften Weiterbildung des Systems weist das System eine Verriegelungseinrichtung auf. Die Verriegelungseinrichtung fixiert das Befestigungselement zu dem Halteelement in dem Zustand, in dem der erste Vorsprung von der ersten Seite aus in einer vorbestimmten Tiefe und dabei beidseitig an der Aussparung anliegt und der zweite Vorsprung an der Anschlagfläche und spielfrei an der Vorspannfläche anliegt.According to another advantageous development of the system, the system has a locking device. The locking device fixes the fastening element to the holding element in the state in which the first projection rests from the first side at a predetermined depth and on both sides of the recess and the second projection rests on the stop surface and without play on the preload surface.

Durch diese Verriegelungseinrichtung kann die Position, in der der zweite Vorsprung an der Anschlagfläche anliegt, gesichert werden, so dass die spielfreie Verbindung zwischen dem Halteelement und dem Befestigungselement beispielsweise auch bei einem Anheben des Tisches an der Tischplatte nicht gelöst wird.This locking device can be used to secure the position in which the second projection rests on the stop surface, so that the play-free connection between the holding element and the fastening element is not released, for example even when the table is lifted on the table top.

Bei einer weiteren vorteilhaften Weiterentwicklung des Systems ist die Verriegelungseinrichtung an dem Halteelement angebracht und weist einen relativ zu dem Halteelement bewegbaren Riegel und ein Vorspannelement, das eingerichtet ist, den Riegel in einer Verriegelungsrichtung in eine Verriegelungsposition zu drängen, in der die Verriegelungseinrichtung die an der Anschlagfläche anliegende Position des zweiten Vorsprungs verriegelt, auf.In a further advantageous development of the system, the locking device is attached to the holding element and has a latch that is movable relative to the holding element and a biasing element that is set up to push the latch in a locking direction into a locking position in which the locking device is on the stop surface the adjacent position of the second projection is locked.

In einer vorteilhaften Weiterbildung eines solchen Systems ist die Verriegelungseinrichtung an dem Halteelement so angeordnet ist und so ausgebildet, dass die Verriegelungsrichtung parallel zu einer Richtung eines Vorstehens des ersten und zweiten Vorsprungs verläuft.In an advantageous development of such a system, the locking device is arranged on the holding element and is designed in such a way that the locking direction runs parallel to a direction of protrusion of the first and second projections.

Durch diese Anordnung besteht die Möglichkeit, die Verriegelung nachträglich ergonomisch wieder zu lösen.This arrangement makes it possible to subsequently release the lock ergonomically.

Gemäß einem anderen Aspekt der Erfindung weist ein Verfahren zum Befestigen eines Möbelbeins an einem Möbel die folgenden Schritte auf: Einbringen des ersten Vorsprungs des Halteelements in die zur ersten Seite hin offene Aussparung des Befestigungselements; Ausführen einer Schwenkbewegung zwischen dem Befestigungselement und dem Halteelement so, dass sich der zweite Vorsprung des Halteelements entlang der Vorspannfläche bewegt, so dass der erste Vorsprung in der vorbestimmten Tiefe in der Aussparung und beidseitig spielfrei anliegt und der zweite Vorsprung an der Anschlagfläche und spielfrei an der Vorspannfläche anliegt.According to another aspect of the invention, a method for attaching a furniture leg to a piece of furniture comprises the following steps: introducing the first projection of the holding element into the recess of the fastening element which is open towards the first side; Executing a pivoting movement between the fastening element and the holding element so that the second projection of the holding element moves along the preloading surface, so that the first projection rests at the predetermined depth in the recess and without play on both sides and the second projection rests on the stop surface and without play on the Pretension surface is in contact.

Durch dieses Verfahren ist es mit einfachen und kostengünstigen Mitteln möglich, das Möbelbein einfach und spielfrei an das Möbel zu montieren.This process makes it possible to mount the furniture leg on the furniture easily and without play using simple and inexpensive means.

Gemäß einer vorteilhaften Weiterentwicklung des Verfahrens wird die Position, in der der zweite Vorsprung an der Anschlagfläche anliegt, verriegelt.According to an advantageous further development of the method, the position in which the second projection rests on the stop surface is locked.

Dadurch kann die Position, in der der zweite Vorsprung an der Anschlagfläche anliegt, gesichert werden, so dass die Verbindung zwischen dem Halteelement und dem Befestigungselement beispielsweise auch bei einem Anheben des Tisches an der Tischplatte nicht gelöst wird.As a result, the position in which the second projection rests on the stop surface can be secured, so that the connection between the holding element and the fastening element is not loosened, for example even when the table is lifted on the table top.

In einer vorteilhaften Weiterentwicklung des Verfahrens wird der zweite Vorsprung zunächst in einen ersten Bereich der Vorspannfläche bewegt, in dem sich ein Abstand zwischen einer Mittelachse einer in der vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung anliegenden ersten Achse als den ersten Vorsprung und der Vorspannfläche entlang dem Verlauf der Vorspannfläche von der zweiten Seite zu der Anschlagfläche vergrößert. Dabei wird eine Vorspannkraft zwischen den Vorsprüngen, der Aussparung und der Vorspannfläche aufzubringen oder eine Spielfreiheit erzeugt. Dann bewegt sich der zweite Vorsprung in einem zweiten Bereich der Vorspannfläche, in dem sich der Abstand verkleinert oder konstant bleibt, um die an der Anschlagfläche anliegende Position des zweiten Vorsprungs selbsttätig zu erhalten.In an advantageous further development of the method, the second projection is first moved into a first region of the prestressing surface, in which a distance between a central axis of a first axis which lies against the recess at the predetermined depth and is free of play on both sides as the first projection and the prestressing surface the course of the preload surface from the second side to the stop surface is increased. A preload force is applied between the projections, the recess and the preload surface or a clearance is created. Then the second projection moves in a second area of the preload surface, in which the distance decreases or remains constant, in order to automatically maintain the position of the second projection resting on the stop surface.

Durch diese Merkmale des Verfahrens kann das Verhalten des Befestigungselements zu dem Halteelement während der Montage beeinflusst werden. Da sich der Abstand in dem ersten Bereich vergrößert, wird bei einer Bewegung der Achse entlang der Vorspannfläche entweder die Vorspannkraft kontrolliert aufgebracht oder allmählich eine Spielfreiheit erzeugt. In dem zweiten Bereich kann dann die Spielfreiheit oder die Vorspannkraft einfach erhalten bleiben, da keine Kraftkomponente so wirkt, dass die Verbindung gelöst wird.These features of the method can influence the behavior of the fastening element to the holding element during assembly. Since the distance in the first area increases, when the axis moves along the preload surface, either the preload force is applied in a controlled manner or a clearance is gradually created. In the second area, the freedom from play or the preload force can then simply be maintained, since no force component acts in such a way that the connection is released.

In einer weiteren vorteilhaften Weiterentwicklung des Verfahrens ist ein Übergang zwischen dem ersten und den zweiten Bereich der Vorspannfläche taktil erfassbar.In a further advantageous development of the method, a transition between the first and second regions of the prestressing surface can be detected tactilely.

Durch den Übergang kann einem Monteur durch ein spür- und/oder auch hörbares Rasten zurückgemeldet werden, dass eine endgültige Montageposition, nämlich die Position, in der der zweite Vorsprung an der Anschlagfläche anliegt und die spielfreie Verbindung hergestellt ist, erreicht ist.Through the transition, a fitter can be informed by a noticeable and/or audible snap that a final assembly position, namely the position in which the second projection rests on the stop surface and the play-free connection is established, has been reached.

Die Erfindung wird nachstehend unter Bezugnahme auf die beigefügten Zeichnungen erläutert.The invention is explained below with reference to the accompanying drawings.

Ferner ist an dem Befestigungselement 4 eine sich an die Vorspannfläche 7 anschließende von der dritten Seite S3 abstehende Anschlagfläche 8 vorgesehen. Ein unteres Ende der Vorspannfläche 7 und die Anschlagfläche 8 sind in dieser Ausführungsform in einer Vertiefung bzw. Ausnehmung des Befestigungselements 4 vorgesehen. In einer alternativen Ausführungsform ist die Vertiefung nicht vorgesehen. Ein Vorsehen der Vorspannfläche 7 und der Anschlagfläche 8 an einer offenen dritten Seite S3 ist ebenfalls möglich.Furthermore, the fastening element 4 has a recess 6 that is open towards the first side S1. Starting from the second side S2, a biasing surface 7 running along the third side S3 is provided. Furthermore, a stop surface 8 protruding from the third side S3 is provided on the fastening element 4, adjoining the pretensioning surface 7. In this embodiment, a lower end of the biasing surface 7 and the stop surface 8 are provided in a recess or recess of the fastening element 4. In an alternative embodiment, the recess is not provided. Providing the biasing surface 7 and the stop surface 8 on an open third side S3 is also possible.

Das Halteelement 5 ist an dem Tisch 1 befestigt. Das Halteelement 5 weist an einer Seite eine erste Achse 9 und eine von der ersten Achse 9 beabstandete zweite Achse 10 auf, die von dem Halteelement 5 von der Seite vorstehen. Die erste Achse 9 und zweite Achse 10 sind parallel angeordnet. In einer alternativen Ausführungsform sind nicht Achsen vorgesehen, sondern ein erster und ein davon beabstandeter zweiter geeignet geformter Vorsprung sind stattdessen vorgesehen. In einer weiteren alternativen Ausführungsform sind die Achsen 9, 10 nicht parallel angeordnet, sondern in einer anderen geeigneten Stellung zueinander, in der eine Vorspannung oder Spielfreiheit auf das System aufgebracht werden kann, ausgerichtet.The holding element 5 is attached to the table 1. The holding element 5 has on one side a first axis 9 and a second axis 10 spaced from the first axis 9, which protrude from the side of the holding element 5.

In an alternative embodiment, axes are not provided, but a first and a second, spaced apart, suitably shaped projection are provided instead. In a further alternative embodiment, the axes 9, 10 are not arranged parallel, but aligned in another suitable position relative to each other in which a preload or freedom from play can be applied to the system.

Die Aussparung 6 des Befestigungselements 4 ist dazu eingerichtet, die erste Achse 9 aufzunehmen. Die Aussparung 6 weist eine Abmessung in Richtung der zweiten Seite S2 auf, die sich von der ersten Seite S1 ausgehend zu der dritten Seite S3 hin verkleinert. Alternativ ist es nicht zwingend erforderlich, dass sich die Abmessung in Richtung der zweiten Seite 2 verkleinert je größer eine Tiefe in der Aussparung 6 ist. Eine gleichbleibende Abmessung in Richtung der zweiten Seite S2 ist ebenfalls möglich, sofern die Abmessung auf einen Durchmesser der ersten Achse 9 so abgestimmt ist, dass ein spielfreies Aufnehmen gewährleistet ist.The recess 6 of the fastening element 4 is designed to accommodate the first axis 9. The recess 6 has a dimension in the direction of the second side S2, which decreases from the first side S1 towards the third side S3. Alternatively, it is not absolutely necessary that the dimension in the direction of the second side 2 decreases the greater the depth in the recess 6. A constant dimension in the direction of the second side S2 is also possible, provided that the dimension is matched to a diameter of the first axis 9 in such a way that play-free recording is guaranteed.

In Fig. 1 ist ein Zustand gezeigt, in dem die erste Achse 9 von der ersten Seite S1 aus in einer vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung 6 anliegt und die zweite Achse 10 an der Anschlagfläche 8 und spielfrei an der Vorspannfläche 7 anliegt. In diesem Zustand sind das Halteelement mit dem ersten Vorsprung und dem zweiten Vorsprung, und das Befestigungselement mit der Aussparung, der Vorspannfläche und der Anschlagfläche dazu eingerichtet, dass eine spielfreie Befestigung des Tischbeins 2 am Tisch 1 ermöglicht wird.In Fig. 1 a state is shown in which the first axis 9 rests against the recess 6 from the first side S1 at a predetermined depth and without play on both sides, and the second axis 10 rests against the stop surface 8 and against the preload surface 7 without play.

Die erste Achse 9 ist bereits von der ersten Seite S1 aus in die vorbestimmte Tiefe eingebracht und liegt dabei beidseitig spielfrei an der Aussparung 6 an. Die zweite Achse 10 ist in einem Zustand dargestellt, in dem sie sich entlang der Vorspannfläche 7 bewegt, um eine Vorspannung zwischen der ersten Achse 9 und der Aussparung 6 zu erzeugen. Alternativ kann eine Spielfreiheit dazwischen aufrechterhalten oder erzeugt werden.The first axis 9 is already inserted into the predetermined depth from the first side S1 and lies against the recess 6 without play on both sides. The second axis 10 is shown in a state in which it moves along the biasing surface 7 to generate a bias between the first axis 9 and the recess 6. Alternatively, clearance can be maintained or created therebetween.

Fig. 3 zeigt eine vergrößerte Detailansicht eines Details A in Fig. 1. Das Halteelement 5 weist eine Öffnung 11 zum Aufnehmen der ersten Achse 9 auf. Die Öffnung 11 weist einen Querschnitt auf, der eingerichtet ist, ein kraftfreies Einführen der ersten Achse 9 zu ermöglichen.

Die Öffnung 11 weist einen ovalen Querschnitt auf, der dazu eingerichtet ist, den freien Querschnitt und die beiden Kontaktpunkte K1, K2 zu ermöglichen. In einer alternativen Ausführungsform weist die Öffnung 11 keine ovale Form, sondern eine andere geeignete Form, beispielsweise eine Ellipse, auf.In the in Fig. 1 State shown, in which the first axis 9 rests against the recess from the first side S1 at the predetermined depth and with no play on both sides, and the second axis 10 rests against the preload surface 7 and the stop surface 8 without play, have the first axis 9 and the opening 11 has two contact points K1, K2. The opening 11 has an oval cross section, which is designed to enable the free cross section and the two contact points K1, K2. In an alternative embodiment, the opening 11 does not have an oval shape, but rather another suitable shape, for example an ellipse.

Gleichzeitig weisen die erste Achse 9 und die Aussparung 6 zwei Kontaktpunkte K3, K4 auf. Dadurch ist die spielfreie Verbindung zwischen dem Befestigungselement 4 und dem Halteelement 5 an der ersten Achse 9 gewährleistet.At the same time, the first axis 9 and the recess 6 have two contact points K3, K4. This ensures the play-free connection between the fastening element 4 and the holding element 5 on the first axis 9.

Fig. 4 zeigt eine vergrößerte Detailansicht eines Details B in Fig. 1. Das Halteelement 4 weist eine Öffnung 12 zum Aufnehmen der zweiten Achse 10 auf. Die Öffnung 12 weist einen Querschnitt auf, der eingerichtet ist, ein kraftfreies Einführen der zweiten Achse 10 zu ermöglichen. Dazu weist die Öffnung 12 einen freien Querschnitt auf, der größer als ein Durchmesser der zweiten Achse 10 ist. Fig. 4 shows an enlarged detailed view of a detail B in Fig. 1 . The holding element 4 has an opening 12 for receiving the second axis 10. The opening 12 has a cross section that is designed to enable force-free insertion of the second axis 10.

In Fig. 1 ist ein Abstand D zwischen einer Mittelachse MA der in der vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung 6 anliegenden ersten Achse 9 und der Vorspannfläche 7 gezeigt, In Fig. 4 ist gezeigt, dass der Abstand D entlang dem Verlauf der Vorspannfläche 7 von der zweiten Seite S2 zu der Anschlagfläche 8 nicht konstant ist.In Fig. 1 is a distance D between a central axis MA of the first axis 9 which lies against the recess 6 at the predetermined depth and without play on both sides and the biasing surface 7 shown, In Fig. 4 it is shown that the distance D along the course of the preload surface 7 from the second side S2 to the stop surface 8 is not constant.

Insbesondere weist die Vorspannfläche 7 einen ersten Bereich 7a auf, entlang dem sich der Abstand D von der zweiten Seite ausgehend vergrößert, um das System durch die Bewegung der zweiten Achse 10 entlang der Vorspannfläche 7 vorzuspannen oder alternativ ein Spiel aus dem System zu eliminieren. Ferner weist die Vorspannfläche 7 einen zweiten Bereich 7b auf, entlang dem sich der Abstand D von dem ersten Bereich 7a ausgehend verkleinert. In einer alternativen Ausführungsform bleibt der Abstand D in dem zweiten Bereich 7b konstant.In particular, the biasing surface 7 has a first region 7a along which the distance D increases starting from the second side in order to bias the system by the movement of the second axis 10 along the biasing surface 7 or alternatively to eliminate play from the system. Furthermore, the biasing surface 7 has a second region 7b, along which the distance D from the first region 7a decreases. In an alternative embodiment, the distance D remains constant in the second region 7b.

In einer alternativen Ausführungsform kann der Abstand zwischen der Mittelachse MA der in der vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung 6 anliegenden ersten Achse 9 und der Vorspannfläche 7 konstant sein, wobei dann eine Spielfreiheit gewährleistet sein kann, ohne das System durch die Bewegung der zweiten Achse 10 entlang der Vorspannfläche 7 vorzuspannen oder weiter vorzuspannen.In an alternative embodiment, the distance between the central axis MA of the first axis 9, which rests against the recess 6 at the predetermined depth and without play on both sides, and the preload surface 7 can be constant, in which case freedom from play can be guaranteed without the system being affected by the movement of the second axis 10 to pretension or further pretension along the pretensioning surface 7.

In Fig. 5 ist dargestellt, dass die zweite Achse 10 zwischen gegenüberliegenden Seiten von dem Halteelement 5 vorstehend angeordnet ist. Obwohl nicht dargestellt, ist auch die erste Achse 9 zwischen den gegenüberliegenden Seiten von dem Halteelement 5 vorstehend angeordnet.In Fig. 5 is shown that the second axis 10 is arranged protruding between opposite sides of the holding element 5. Although not shown, the first axis 9 is also arranged projecting between the opposite sides of the holding element 5.

Das Befestigungselement 5 weist zwei Aussparungen 6 auf, die jeweils die erste Achse 9 aufnehmen und zwei Vorspannflächen 7 und zwei Anschlagflächen 8 auf, an denen dann jeweils die zweite Achse 10 anliegt.The fastening element 5 has two recesses 6, each of which accommodates the first axis 9, and two biasing surfaces 7 and two stop surfaces 8, against which the second axis 10 then rests.

In einer alternativen Ausführungsform stehen die erste und zweite Achse 9, 10 lediglich einseitig von einer Seite des Halteelements 5 oder beidseitig von dem Haltelement 5 nach außen vor, wobei dann ggf. nur eine Aussparung 8 und jeweils nur eine Vorspannfläche 7 und Anschlagfläche 8 vorgesehen sind.In an alternative embodiment, the first and second axles 9, 10 are only on one side of one side of the holding element 5 or on both sides of it Holding element 5 outwards, in which case only one recess 8 and only one preload surface 7 and stop surface 8 are provided.

Die Verriegelungseinrichtung 13 ist an dem Halteelement 5 angebracht und weist einen relativ zu dem Halteelement 5 bewegbaren Riegel 14 auf. Ferner weist die Verriegelungseinrichtung 13 ein Vorspannelement 15 auf, das den Riegel 14 in einer Verriegelungsrichtung VR in eine Verriegelungsposition drängt, in der die Verriegelungseinrichtung 13 die an der Anschlagfläche 8 anliegende Position der zweiten Achse 10 verriegelt.The locking device 13 is attached to the holding element 5 and has a latch 14 that is movable relative to the holding element 5. Furthermore, the locking device 13 has a biasing element 15 which pushes the bolt 14 in a locking direction VR into a locking position in which the locking device 13 locks the position of the second axis 10 resting on the stop surface 8.

Dadurch wird das Befestigungselement 4 in dem Zustand, in dem die erste Achse 9 von der ersten Seite S1 aus in der vorbestimmten Tiefe und dabei beidseitig an der Aussparung 6 anliegt und die zweite Achse 10 an der Anschlagfläche 8 und spielfrei an der Vorspannfläche 7 anliegt, zu dem Halteelement 5 fixiert.As a result, the fastening element 4 is in the state in which the first axis 9 rests on the recess 6 from the first side S1 at the predetermined depth and on both sides and the second axis 10 rests on the stop surface 8 and without play on the preload surface 7, fixed to the holding element 5.

Die Verriegelungseinrichtung 13 ist an dem Halteelement 5 so angeordnet, dass die Verriegelungsrichtung VR parallel zu einer Richtung des Vorstehens der ersten und zweiten Achse 9, 10 verläuft.The locking device 13 is arranged on the holding element 5 such that the locking direction VR runs parallel to a direction of protrusion of the first and second axes 9, 10.

In alternativen Ausführungsformen kann die Verriegelungseinrichtung 13 nicht mit einem Vorspannelement versehen sein und stattdessen manuell verriegelbar sein, weiterhin kann sie nicht an dem Halteelement, sondern an dem Befestigungselement angebracht sein und außerdem eine andere Verriegelungsrichtung aufweisen. Wesentlich ist, dass das System in dem Zustand, in dem die erste Achse 9 von der ersten Seite S1 aus in der vorbestimmten Tiefe und dabei beidseitig an der Aussparung 6 anliegt und die zweite Achse 10 an der Anschlagfläche 8 und spielfrei an der Vorspannfläche 7 anliegt, fixiert wird.In alternative embodiments, the locking device 13 may not be provided with a biasing element and instead may be manually lockable; furthermore, it may not be attached to the holding element but to the fastening element and may also have a different locking direction. It is essential that the system is in the state in which the first axis 9 rests against the recess 6 from the first side S1 at the predetermined depth and on both sides and the second axis 10 rests against the stop surface 8 and against the preload surface 7 without play , is fixed.

Im Betrieb wird zum Befestigen des Tischbeins 2 zunächst die erste Achse 9 des Halteelements 5 in die zur ersten Seite S1 hin offene Aussparung 6 des Befestigungselements 4 eingebracht. Das Halteelement 5 wird dabei so weit bewegt, dass die erste Achse 9 beidseitig an der Aussparung 6 anliegt. Dadurch ist gewährleistet, dass die zweite Achse 10 so positioniert ist, dass sie sich ohne Kollision mit der zweiten Seite S2 des Halteelements 5 an der Vorspannfläche 7 des Halteelements 5 entlang bewegen kann. Andererseits liegt, wenn die erste Achse 9 nicht ausreichend tief in die Aussparung 6 eingebracht wurde, die zweite Achse 10 auf der zweiten Seite S2 auf und das Halteelement 5 kann relativ zu dem Befestigungselement 4 so bewegt werden, dass die zweite Achse 10 zu der Vorspannfläche 7 gelangt.During operation, to fasten the table leg 2, the first axis 9 of the holding element 5 is first inserted into the recess 6 of the fastening element 4, which is open towards the first side S1. The holding element 5 is moved so far that the first axis 9 rests on the recess 6 on both sides. This ensures that the second axis 10 is positioned so that it can move without collision with the second side S2 of the holding element 5 can move along the biasing surface 7 of the holding element 5. On the other hand, if the first axis 9 has not been inserted sufficiently deeply into the recess 6, the second axis 10 rests on the second side S2 and the holding element 5 can be moved relative to the fastening element 4 so that the second axis 10 faces the biasing surface 7 arrived.

Anschließend wird eine Schwenkbewegung zwischen dem Befestigungselement 4 und dem Halteelement 5 ausgeführt, so dass sich die zweite Achse 10 des Halteelements 5 entlang der Vorspannfläche 7 des Befestigungselements 4 bewegt bis die erste Achse 9 in der vorbestimmten Tiefe in der Aussparung 6 und dabei beidseitig spielfrei anliegt und die zweite Achse an der Anschlagfläche 8 und spielfrei an der Vorspannfläche 7 anliegt. In Abhängigkeit von der Montagestellung des Tischs 1 wird das Befestigungselement bezüglich des Halteelements 5 oder das Halteelement 5 bezüglich des Befestigungselements 4 geschwenkt.A pivoting movement is then carried out between the fastening element 4 and the holding element 5, so that the second axis 10 of the holding element 5 moves along the biasing surface 7 of the fastening element 4 until the first axis 9 rests at the predetermined depth in the recess 6 and there is no play on both sides and the second axis rests on the stop surface 8 and without play on the preload surface 7. Depending on the mounting position of the table 1, the fastening element is pivoted with respect to the holding element 5 or the holding element 5 is pivoted with respect to the fastening element 4.

Beim Ausführen der Schwenkbewegung zwischen dem Befestigungselement 4 und dem Halteelement 5 in die Position, in der die zweite Achse 10 an der Anschlagfläche 8 anliegt, wird, sofern die Verriegelungseinrichtung 13 mit dem Vorspannelement 15 für eine automatische Verriegelung vorgesehen ist, das System 3 automatisch verriegelt.When the pivoting movement between the fastening element 4 and the holding element 5 is carried out into the position in which the second axis 10 rests on the stop surface 8, the system 3 is automatically locked, provided that the locking device 13 with the biasing element 15 is provided for automatic locking .

Bei der Schwenkbewegung bewegt sich die zweite Achse 10 zunächst in dem ersten Bereich 7a der Vorspannfläche 7, in dem sich ein Abstand zwischen der Mittelachse MA der in der vorbestimmten Tiefe und dabei beidseitig spielfrei an der Aussparung 6 anliegenden ersten Achse 9 und der Vorspannfläche 7 entlang dem Verlauf der Vorspannfläche 7 von der zweiten Seite S2 zu der Anschlagfläche 8 vergrößert, um eine Vorspannkraft zwischen den Achsen 9, 10, der Aussparung 6 und der Vorspannfläche 7 zu erzeugen. Anschließend bewegt sich die zweite Achse 10 dann in dem zweiten Bereich 7b der Vorspannfläche 7, in dem sich der Abstand D verkleinert, um die an der Anschlagfläche 8 anliegende Position der zweiten Achse 10 zwangsgeführt zu erhalten. Dabei wird ein Übergang zwischen dem ersten und dem zweiten Bereich gegebenenfalls taktil erfasst. Alternativ wird das System 3 durch die Schwenkbewegung lediglich spielfrei, ohne dass eine Vorspannkraft erzeugt wird.During the pivoting movement, the second axis 10 initially moves in the first area 7a of the pretensioning surface 7, in which a distance between the central axis MA of the first axis 9, which lies against the recess 6 at the predetermined depth and without play on both sides, and the pretensioning surface 7 the course of the preload surface 7 from the second side S2 to the stop surface 8 is increased in order to generate a preload force between the axes 9, 10, the recess 6 and the preload surface 7. The second axis 10 then moves in the second region 7b of the pretensioning surface 7, in which the distance D decreases in order to maintain the position of the second axis 10 resting against the stop surface 8 in a positively guided manner. There will be a transition between the first and the second area if necessary detected tactilely. Alternatively, the system 3 is simply free of play due to the pivoting movement, without any preload force being generated.
