Description

Möbelbeschlag und Verfahren zur Herstellung eines Möbelbeschlages Furniture fitting and method for producing a furniture fitting
Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Möbelbeschlages zur bewegbaren Lagerung wenigstens eines Möbelteiles an einem Möbelkorpus. The present invention relates to a method for producing a furniture fitting for movably mounting at least one furniture part on a furniture body.
Im Weiteren betrifft die Erfindung einen Möbelbeschlag der zu beschreibenden Art. The invention also relates to a furniture fitting of the type to be described.
Die gelenkige Verbindung zwischen zwei Bauteilen eines Möbelbeschlages wird häufig so hergestellt, indem die Bauteile jeweils mit einer Öffnung versehen werden, ein Stift durch die Öffnungen der beiden Bauteile hindurchgesteckt und dann zumindest ein Ende des Stifts durch Taumeln verbreitert wird. Auf diese Weise sind die beiden Bauteile in einer axialen Richtung des Stiftes relativ zueinander festgelegt. The articulated connection between two components of a furniture fitting is often produced in that the components are each provided with an opening, a pin is inserted through the openings of the two components and then at least one end of the pin is widened by tumbling. In this way, the two components are fixed relative to one another in an axial direction of the pin.
Nachteilig daran ist, dass die Kosten zur Herstellung des Möbelbeschlages, insbesondere bei zahlreicher Anordnung von Stiften, erhöht sind. Außerdem besteht bei einem Kaltumformverfahren wie dem Taumeln die Gefahr, dass sich Risse am Stift bilden können. Werden diese Risse durch ein optisches Erkennungssystem oder durch Stichproben rechtzeitig detektiert, so kann der Stift sogleich ausgetauscht werden. Kleinere Fissuren des Stifts bleiben hingegen oft unbemerkt und können zu einem späteren Zeitpunkt zu einem Bruch der Verbindung zwischen den Bauteilen des Möbelbeschlages führen. The disadvantage of this is that the costs for producing the furniture fitting are increased, in particular when there are a large number of pins. In addition, with a cold forming process such as tumbling, there is a risk that cracks can form on the pin. If these cracks are detected in time by an optical detection system or by spot checks, the pin can be replaced immediately. Smaller fissures in the pin, on the other hand, often go unnoticed and can later lead to a break in the connection between the components of the furniture fitting.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zur Herstellung eines Möbelbeschlages sowie einen verbesserten Möbelbeschlag unter Vermeidung der oben diskutierten Nachteile anzugeben. The object of the present invention is to specify a method for producing a furniture fitting and an improved furniture fitting while avoiding the disadvantages discussed above.
Dies wird erfindungsgemäß durch die Merkmale der Patentansprüche 1 und 13 gelöst. According to the invention, this is achieved by the features of patent claims 1 and 13 .
Das Verfahren zur Herstellung eines Möbelbeschlages zur bewegbaren Lagerung wenigstens eines Möbelteiles an einem Möbelkorpus weist die folgenden, vorzugsweise in der angegebenen Reihenfolge zeitlich aufeinanderfolgenden, Verfahrensschritte auf: - es wird in einem ersten Verfahrensschritt wenigstens ein, vorzugsweise plattenförmiger, Grundkörper bereitgestellt, The method for producing a furniture fitting for the movable mounting of at least one furniture part on a furniture body has the following method steps, preferably in the order given in chronological order: - in a first method step, at least one, preferably plate-shaped, base body is provided,
- es wird in einem zweiten Verfahrensschritt wenigstens eine, vorzugsweise zylindrische, Öffnung mit wenigstens einem die Öffnung umgebenden Kragen in den wenigstens einen Grundkörper eingebracht, wobei der wenigstens eine Kragen vom wenigstens einen Grundkörper absteht, - in a second process step, at least one, preferably cylindrical, opening with at least one collar surrounding the opening is introduced into the at least one base body, with the at least one collar protruding from the at least one base body,
- der wenigstens eine Kragen wird in einem dritten Verfahrensschritt zumindest bereichsweise erhitzt, und - The at least one collar is at least partially heated in a third method step, and
- der wenigstens eine Kragen wird in einem vierten Verfahrensschritt im erhitzten Zustand durch eine mechanische Umformung in zumindest einer radialen Richtung zu einer, vorzugsweise ringförmigen, Wulst verbreitert. - The at least one collar is widened in a fourth process step in the heated state by mechanical deformation in at least one radial direction to form a preferably annular bead.
Somit wird in einem ersten Verfahrensschritt ein Grundkörper bereitgestellt. Der Grundkörper kann beispielsweise durch Stanzen aus einem, vorzugsweise ebenen, Blech, vorzugsweise aus Stahl, hergestellt werden. A base body is thus provided in a first method step. The base body can be produced, for example, by stamping from a preferably flat sheet metal, preferably made of steel.
Die Materialstärke des ebenen Grundkörpers kann vorzugsweise zwischen 0,5 mm und 1,0 mm betragen. The material thickness of the planar base body can preferably be between 0.5 mm and 1.0 mm.
In einem zweiten Verfahrensschritt wird eine Öffnung in den Grundkörper eingebracht, wobei ein Kragen gezogen wird. Dieser Kragen bildet ein Drehlager mit einer vergrößerten Abstützfläche aus. Der Kragen kann beispielsweise durch Kragenziehen hergestellt werden. Die Öffnung im Grundkörper kann beispielsweise durch eine Bohrung gebildet sein. In a second process step, an opening is made in the base body, with a collar being drawn. This collar forms a pivot bearing with an enlarged support surface. The collar can be produced, for example, by collaring. The opening in the base body can be formed by a bore, for example.
In einem dritten Verfahrensschritt wird der Kragen, vorzugsweise das freie Ende des Kragens, lokal erhitzt. Diese Erhitzung kann beispielsweise durch ein schnell rotierendes Werkzeug herbeigeführt werden, welches an den Kragen angedrückt wird. Durch die auftretende Reibung wird das Material des Kragens plastifiziert, d.h. in einen verformbaren oder fließfähigen Zustand gebracht. In a third method step, the collar, preferably the free end of the collar, is locally heated. This heating can be brought about, for example, by a rapidly rotating tool which is pressed against the collar. The friction that occurs plasticizes the material of the collar, i.e. it puts it in a deformable or flowable state.
In einem vierten Verfahrensschritt wird der Kragen im erhitzten Zustand umgeformt, wobei ein verbreiterter Wulst gebildet wird. Durch eine auf den Kragen ausgeübte Axialkraft und durch die hohe Drehzahl des rotierenden Werkzeuges wird das Material des Kragens in einer radialen Richtung verdrängt, wobei eine charakteristische Wulst entsteht. Durch diese Wulst sind die miteinander zu verbindenden Bauteile des Möbel beschlages in einer axialen Richtung des Kragens relativ zueinander festlegbar. In a fourth process step, the collar is shaped in the heated state, with a widened bead being formed. By an axial force exerted on the collar and by the high speed of the rotating tool, the material of the collar is displaced in a radial direction, creating a characteristic bulge. This bead allows the components of the furniture fitting to be connected to one another to be fixed relative to one another in an axial direction of the collar.
Durch das vorgeschlagene Verfahren ergeben sich einige Vorteile. Zunächst kann auf zusätzliche Befestigungsmittel (wie beispielsweise einen Stift) zur Verbindung der beiden Bauteile des Möbelbeschlages verzichtet werden, wodurch die Kosten in der serienmäßigen Herstellung des Möbelbeschlages signifikant reduziert werden können. Folglich kann im Werk auch auf eine eigene Zuführstation zur Bereitstellung von zusätzlichen Befestigungsmitteln, insbesondere Stiften, verzichtet werden. The proposed method results in a number of advantages. First of all, additional fastening means (such as a pin) for connecting the two components of the furniture fitting can be dispensed with, as a result of which the costs in the series production of the furniture fitting can be significantly reduced. Consequently, there is no need for a separate feed station in the factory to provide additional fastening means, in particular pins.
Durch die stattfindende Wärmebehandlung ist auch eine definierte und spanlose Umformung, eine höhere Festigkeit des Kragens sowie eine glatte Oberfläche der produzierten Wulst erzielbar. Im Ergebnis kann am freien Ende des Kragens eine charakteristische, torusförmige Wulst vorhanden sein. The heat treatment that takes place also makes it possible to achieve defined and non-cutting forming, greater strength of the collar and a smooth surface of the bead produced. As a result, a distinctive toroidal ridge may be present at the free end of the collar.
Der Kragen kann sich durch die Zuführung von Hitze im Zuge des dritten Verfahrensschritts im erhitzten Bereich verfärben (beispielsweise eine Schwarzfärbung oder eine Blaufärbung), wodurch sich auch besondere optische Effekte erzielen lassen. Beispielsweise kann der Grundkörper des Möbelbeschlages eine übliche Zinkfarbe aufweisen, wohingegen die Drehachsen des Möbelantriebes an den beiden Enden durch die Erhitzung schwarz gefärbt sind. The collar can discolor in the heated area (for example black or blue) due to the application of heat in the course of the third process step, which also allows special optical effects to be achieved. For example, the base body of the furniture fitting can have a conventional zinc color, whereas the rotary axes of the furniture drive are colored black at both ends as a result of the heating.
Der Möbelbeschlag gemäß der Erfindung weist wenigstens einen, vorzugsweise plattenförmigen, Grundkörper auf, wobei der wenigstens eine Grundkörper wenigstens eine, vorzugsweise zylindrische, Öffnung mit wenigstens einem die Öffnung umgebenden Kragen aufweist, wobei der wenigstens eine Kragen vom wenigstens einen Grundkörper absteht. Der wenigstens eine Kragen weist wenigstens eine in zumindest einer radialen Richtung sich erstreckende, vorzugsweise ringförmige, Wulst auf. Vorzugsweise ist vorgesehen, dass der Möbelbeschlag mittels des beschriebenen Verfahrens hergestellt ist. Weitere Einzelheiten und Vorteile der vorliegenden Erfindung ergeben sich aus der nachfolgenden Figuren beschreibung. The furniture fitting according to the invention has at least one, preferably plate-shaped, base body, the at least one base body having at least one, preferably cylindrical, opening with at least one collar surrounding the opening, the at least one collar protruding from the at least one base body. The at least one collar has at least one preferably annular bead extending in at least one radial direction. Provision is preferably made for the furniture fitting to be produced using the method described. Further details and advantages of the present invention result from the following description of the figures.

Fig. la-ld zeigen das Verfahren zur Fierstellung eines Möbelbeschlages 1 in verschiedenen Verfahrensschritten, nämlich Fig. La-ld show the method for Fierstellung a furniture fitting 1 in different steps, viz
- in einem ersten Verfahrensschritt (A) wird wenigstens ein, vorzugsweise plattenförmiger, Grundkörper 2 bereitgestellt (Fig. la), - In a first method step (A), at least one, preferably plate-shaped, base body 2 is provided (Fig. La),
- in einem zweiten Verfahrensschritt (B) wird wenigstens eine, vorzugsweise zylindrische, Öffnung 3 mit wenigstens einem die Öffnung 3 umgebenden Kragen 4 in den wenigstens einen Grundkörper 2 eingebracht, wobei der wenigstens eine Kragen 4 vom wenigstens einen Grundkörper 2 absteht, vorzugsweise wobei der Kragen 4 eine Stirnseite 13 aufweist (Fig. lb), - In a second process step (B), at least one, preferably cylindrical, opening 3 with at least one collar 4 surrounding the opening 3 is introduced into the at least one base body 2, with the at least one collar 4 protruding from the at least one base body 2, preferably with the Collar 4 has an end face 13 (Fig. lb),
- in einem dritten Verfahrensschritt (C) wird der wenigstens eine Kragen 4, vorzugsweise durch eine Wärmequelle 5, besonders bevorzugt durch ein rotierendes Werkzeug 5a, zumindest bereichsweise erhitzt (Fig. lc), und - in einem vierten Verfahrensschritt (D) wird der wenigstens eine Kragen 4 im erhitzten Zustand durch eine mechanische Umformung, vorzugsweise durch das rotierende Werkzeug 5a, in zumindest einer radialen Richtung zu einer, vorzugsweise ringförmigen, Wulst 6 verbreitert (Fig. Id). - In a third method step (C), the at least one collar 4, preferably by a heat source 5, particularly preferably by a rotating tool 5a, at least partially heated (Fig. Lc), and - In a fourth process step (D), the at least one collar 4 is widened in the heated state by mechanical forming, preferably by the rotating tool 5a, in at least one radial direction to form a preferably annular bead 6 (Fig. Id).
Der Möbelbeschlag 1 bildet gemäß Fig. Id eine, vorzugsweise bereichsweise zylindrische, Lagerstelle 7 für ein Bauteil 11 (Fig. 2) des Möbelbeschlages 1 aus. Das Bauteil 11 des Möbelbeschlages 1 ist in einem montierten Zustand bereichsweise zwischen dem Grundkörper 2 und der Wulst 6 an einem hohlzylindrischen Abschnitt 16 des Kragens 4 aufgenommen und um eine vom Kragen 4 gebildete Achse schwenkbar gelagert. According to FIG. 1d, the furniture fitting 1 forms a bearing point 7, preferably cylindrical in some areas, for a component 11 (FIG. 2) of the furniture fitting 1. The component 11 of the furniture fitting 1 is accommodated in a mounted state in regions between the base body 2 and the bead 6 on a hollow-cylindrical section 16 of the collar 4 and pivoted about an axis formed by the collar 4 .
Auf die zusätzliche Anordnung von Befestigungsmitteln, insbesondere Stiften, kann somit verzichtet werden. The additional arrangement of fastening means, in particular pins, can thus be dispensed with.
Fig. 2 zeigt eine perspektivische Ansicht eines Möbelbeschlages 1, welcher im gezeigten Ausführungsbeispiel zur lösbaren Verriegelung einer Schubladenfrontblende mit einer Schubladenseitenwand ausgebildet ist. Fig. 2 shows a perspective view of a furniture fitting 1, which is designed in the embodiment shown for the releasable locking of a drawer front panel with a drawer side wall.
Der Möbelbeschlag 1 ist in einem montierten Zustand an einem vorderen Ende der Schubladenseitenwand angeordnet und weist typischerweise ein um eine Drehachse 8 schwenkbares Fangelement 9 mit einer Fangöffnung 12 auf. Im gezeigten Ausführungsbeispiel entspricht das Fangelement 9 dem Grundkörper 2. In a mounted state, the furniture fitting 1 is arranged on a front end of the drawer side wall and typically has a catch element 9 which can be pivoted about a rotation axis 8 and has a catch opening 12 . In the exemplary embodiment shown, the catch element 9 corresponds to the base body 2.
An der Rückseite der Schubladenfrontblende ist ein (hier nicht gezeigtes) Halteteil zu befestigen. Das Fangelement 9 ist durch einen Eintritt des Halteteiles in die Fangöffnung 12 auslösbar, wobei das Fangelement 9 (zusammen mit dem damit gekoppelten Halteteil) durch die Kraft eines Kraftspeichers 10 einziehbar ist. Auf diese Weise ist die Schubladenfrontblende gegen die vordere Stirnseite der Schubladenseitenwand drückbar. Solche Möbelbeschläge 1 sind vom Aufbau grundsätzlich bekannt und brauchen an dieser Stelle nicht näher beschrieben zu werden. A bracket (not shown) attaches to the rear of the drawer front panel. The catching element 9 can be triggered by the holding part entering the catching opening 12 , with the catching element 9 (together with the holding part coupled thereto) being retractable by the force of an energy accumulator 10 . In this way, the drawer front panel can be pressed against the front face of the drawer side wall. Such furniture fittings 1 are basically known in terms of structure and do not need to be described in more detail at this point.
Der Kraftspeicher 10, beispielsweise in Form einer als Druckfeder ausgebildeten Schraubenfeder, drückt über das Bauteil 11 gegen die Lagerstelle 7 des Möbelbeschlages 1. Das Bauteil 11 ist an der Lagerstelle 7 schwenkbar gelagert. Zu erkennen ist, dass das Bauteil 11 bereichsweise zwischen dem Grundkörper 2 (d.h. dem Fangelement 9) und der Wulst 6 aufgenommen ist. Auf diese Weise ist die Position des Bauteiles 11 in einer axialen Richtung der Lagerstelle 7 festgelegt. The energy accumulator 10, for example in the form of a helical spring designed as a compression spring, presses via the component 11 against the bearing point 7 of the furniture fitting 1. The component 11 is on the bearing point 7 pivotally mounted. It can be seen that the component 11 is accommodated in regions between the base body 2 (ie the catch element 9) and the bead 6. In this way, the position of the component 11 is fixed in an axial direction of the bearing point 7 .
Es ist jedoch keinesfalls notwendig, dass das Bauteil 11 die Lagerstelle 7, insbesondere den hohlzylindrischen Abschnitt 16 (Fig. Id), vollständig umgreift und damit unlösbar mit der Lagerstelle 7 verbunden ist. Stattdessen kann das Bauteil 11 einen klammerförmigen Abschnitt aufweisen, durch welchen das Bauteil 11 mit der Lagerstelle 7 lösbar verbindbar ist. Zum Lösen der Verbindung zwischen dem Bauteil 11 und der Lagerstelle 7 ist es ausreichend, das Bauteil 11 entgegen der Kraft des Kraftspeichers 10 zu bewegen und den klammerförmigen Abschnitt des Bauteiles 11 von der Lagerstelle 7 zu trennen. However, it is by no means necessary for the component 11 to completely encompass the bearing point 7, in particular the hollow-cylindrical section 16 (FIG. 1d), and thus be permanently connected to the bearing point 7. Instead, the component 11 can have a clip-shaped section, through which the component 11 can be releasably connected to the bearing point 7 . In order to release the connection between the component 11 and the bearing point 7, it is sufficient to move the component 11 against the force of the energy accumulator 10 and to separate the clamp-shaped section of the component 11 from the bearing point 7.
Fig. 3a-3c zeigen den Möbelbeschlag 1 gemäß Fig. 2 in einer perspektivischen Ansicht sowie zwei verschiedene Detaildarstellungen hierzu. 3a-3c show the furniture fitting 1 according to FIG. 2 in a perspective view and two different detailed representations of this.
In Fig. 3a ist der Möbelbeschlag 1 erkennbar, wobei der vom Grundkörper 2 quer abstehende Kragen 4 im Zuge des ersten und zweiten Verfahrensschritts bereits hergestellt wurde. Der Kragen 4 ist bereichsweise zylindrisch ausgebildet und weist eine vom Grundkörper 2 abgewandte Stirnseite 13 auf. The furniture fitting 1 can be seen in FIG. 3a, the collar 4 projecting transversely from the base body 2 having already been produced in the course of the first and second method steps. The collar 4 is cylindrical in some areas and has an end face 13 facing away from the base body 2 .
Im Zuge des dritten Verfahrensschritts wird der Kragen 4 zumindest an der Stirnseite 13 durch eine Wärmequelle 5, vorzugsweise durch das rotierende Werkzeug 5a, erhitzt. In the course of the third method step, the collar 4 is heated at least on the end face 13 by a heat source 5, preferably by the rotating tool 5a.
Fig. 3b zeigt den in Fig. 3a eingekreisten Bereich in einer vergrößerten Ansicht. Das rotierende Werkzeug 5a weist einen Zentrierstift 15 und eine ringförmige Erhebung 14 auf. Ein solches Werkzeug 5a kann beispielsweise einen so genannten Fließbohrer aufweisen, welcher mit hoher Geschwindigkeit rotiert und zumindest bereichsweise in den wenigstens einen Kragen 4 und/oder die Öffnung 3 eingeführt wird. FIG. 3b shows the circled area in FIG. 3a in an enlarged view. The rotating tool 5a has a centering pin 15 and an annular elevation 14 . Such a tool 5a can, for example, have what is known as a flow drill, which rotates at high speed and is inserted at least in regions into the at least one collar 4 and/or the opening 3 .
Die ringförmige Erhebung 14 des Werkzeuges 5a wird im Zuge des dritten Verfahrensschritts in Kontakt mit dem wenigstens einen Kragen 4, vorzugsweise mit der Stirnseite 13 des Kragens 4, gebracht. Fig. 3c zeigt das in den Kragen 4 eingeführte Werkzeug 5a, wobei die Wulst 6 (Fig. 2) im Zuge des vierten Verfahrensschritts mittels des Werkzeuges 5a gebildet wird. Durch das Werkzeug 5a wird ein Druck in eine axiale Richtung des Kragens 4 ausgeübt. Auf diese Weise wird die Wulst 6 im Zuge des vierten Verfahrensschritts an einem vom wenigstens einen Grundkörper 2 beabstandeten Ende des Kragens 4 ausgebildet. The ring-shaped elevation 14 of the tool 5a is brought into contact with the at least one collar 4, preferably with the end face 13 of the collar 4, in the course of the third method step. FIG. 3c shows the tool 5a inserted into the collar 4, the bead 6 (FIG. 2) being formed by means of the tool 5a in the course of the fourth method step. A pressure is exerted in an axial direction of the collar 4 by the tool 5a. In this way, the bead 6 is formed in the course of the fourth method step on an end of the collar 4 spaced apart from the at least one base body 2 .
Am Kragen 4 zwischen der Wulst 6 und dem Grundkörper 2 verbleibt wenigstens ein hohlzylindrischer Abschnitt 16 (Fig. Id, Fig. 4b), welcher einen kleineren Durchmesser als die Wulst 6 aufweist. Dieser hohlzylindrische Abschnitt 16 des Kragens 4 dient zur, vorzugsweise schwenkbaren, Lagerung des Bauteiles 11 des Möbelbeschlages 1. At least one hollow cylindrical section 16 (FIG. 1d, FIG. 4b), which has a smaller diameter than the bead 6, remains on the collar 4 between the bead 6 and the base body 2. FIG. This hollow-cylindrical section 16 of the collar 4 is used for the preferably pivotable mounting of the component 11 of the furniture fitting 1.
Fig. 4a zeigt den Grundkörper 2 (Fangelement 9) mit dem vom Grundkörper 2 quer abstehenden Kragen 4 in einem unverformten Zustand. Durch das rotierende Werkzeug 5a wird die Stirnseite 13 des Kragens 4 derart erhitzt, dass das Material des Kragens 4 in einen plastifizierten Zustand überführbar ist. 4a shows the base body 2 (catching element 9) with the collar 4 projecting transversely from the base body 2 in an undeformed state. The end face 13 of the collar 4 is heated by the rotating tool 5a in such a way that the material of the collar 4 can be converted into a plasticized state.
Fig. 4b zeigt den Grundkörper 2 (Fangelement 9) mit dem vom Grundkörper 2 quer abstehenden Kragen 4 in einem verformten Zustand. Durch Andrücken des Werkzeuges 5a gegen die Stirnseite 13 des Kragens 4 und durch die hohe Drehzahl des Werkzeuges 5a wird der Kragen 4 in einer radialen Richtung zu einer, vorzugsweise ringförmigen, Wulst 6 verbreitert. 4b shows the base body 2 (catching element 9) with the collar 4 protruding transversely from the base body 2 in a deformed state. By pressing the tool 5a against the end face 13 of the collar 4 and by the high speed of the tool 5a, the collar 4 is widened in a radial direction to form a preferably annular bead 6 .
Zwischen der Wulst 6 und dem Grundkörper 2 verbleibt wenigstens ein hohlzylindrischer Abschnitt 16, welcher einen kleineren Durchmesser als die Wulst 6 aufweist. At least one hollow-cylindrical section 16 , which has a smaller diameter than the bead 6 , remains between the bead 6 and the base body 2 .
Das schwenkbare Bauteil 11 kann entweder unmittelbar nach der Herstellung des Kragens 4 an der Lagerstelle 7 angeordnet werden, wobei anschließend die Wulst 6 hergestellt wird. In einem montierten Zustand ist das Bauteil 11 bereichsweise zwischen dem Grundkörper 2 und der Wulst 6 aufgenommen. The pivotable component 11 can either be arranged at the bearing point 7 immediately after the production of the collar 4, with the bead 6 then being produced. In an assembled state, the component 11 is accommodated in some areas between the base body 2 and the bead 6 .
Alternativ kann das Bauteil 11 auch nach der Herstellung der Wulst 6 an der Lagerstelle 7 angeordnet werden. Dies kann beispielsweise durch eine den hohlzylindrischen Abschnitt 16 nur teilweise umgreifende Klammer des Bauteiles 11 ermöglicht werden, wobei das Bauteil 11 auch nach der Herstellung der Wulst 6 mit der Lagerstelle 7 lösbar verbindbar ist. Alternatively, the component 11 can also be arranged at the bearing point 7 after the bead 6 has been produced. This can, for example, by the hollow cylindrical section 16 only Partially encompassing clip of the component 11 can be made possible, the component 11 being releasably connectable to the bearing point 7 even after the bead 6 has been produced.
Fig. 5a zeigt eine perspektivische Ansicht eines Möbelbeschlages 1 in einer geringfügig modifizierten Ausführungsform, wobei die Wulst 6 der Lagerstelle 7 erst nach der Anbringung des drehbaren Bauteiles 11 gebildet wird. 5a shows a perspective view of a furniture fitting 1 in a slightly modified embodiment, with the bead 6 of the bearing point 7 being formed only after the rotatable component 11 has been attached.
Der Kraftspeicher 10 ist über die Gelenkachse 17 schwenkbar mit dem um die Drehachse 8 schwenkbaren Bauteil 11 verbunden. The energy accumulator 10 is pivotably connected via the joint axis 17 to the component 11 pivotable about the axis of rotation 8 .
In einem ersten und zweiten Verfahrensschritt wird zunächst der Grundkörper 2 mit dem Kragen 4 bereitgestellt. In einem weiteren Verfahrensschritt wird das Bauteil 11 drehbar am Kragen 4 angeordnet. In a first and second method step, the base body 2 with the collar 4 is first provided. In a further method step, the component 11 is arranged on the collar 4 such that it can rotate.
Fig. 5b zeigt den in Fig. 5a eingekreisten Bereich in einer vergrößerten Ansicht, wobei das Bauteil 11 am Kragen 4 der Lagerstelle 7 vorpositioniert ist. FIG. 5b shows the area circled in FIG. 5a in an enlarged view, the component 11 being pre-positioned on the collar 4 of the bearing point 7. FIG.
Fig. 5c zeigt den Bereich der Lagerstelle 7, nachdem der Kragen 4 in einem dritten Verfahrensschritt erhitzt und in einem vierten Verfahrensschritt in einer radialen Richtung zu einer, vorzugsweise ringförmigen, Wulst 6 umgeformt wurde. Das drehbare Bauteil 11 ist in einem montierten Zustand um die Drehachse 8 der Lagerstelle 7 drehbar gelagert und bereichsweise zwischen dem Grundkörper 2 und der Wulst 6 aufgenommen. 5c shows the area of the bearing point 7 after the collar 4 has been heated in a third method step and shaped in a radial direction into a preferably annular bead 6 in a fourth method step. In a mounted state, the rotatable component 11 is mounted so that it can rotate about the axis of rotation 8 of the bearing point 7 and is accommodated in regions between the base body 2 and the bead 6 .
Die Erfindung wurde in den Figuren anhand eines Möbelbeschlages 1 zum lösbaren Befestigen einer Schubladenfrontblende mit einer Schubladenseitenwand erläutert. Selbstverständlich kann der Möbelbeschlag 1 auch als Möbelantrieb zum Bewegen einer Möbelklappe, als Möbelscharnier zur bewegbaren Lagerung eines Möbelteiles oder als Schubladenausziehführung ausgebildet sein. The invention was explained in the figures using a furniture fitting 1 for detachably fastening a drawer front panel to a drawer side wall. Of course, the furniture fitting 1 can also be designed as a furniture drive for moving a furniture flap, as a furniture hinge for the movable mounting of a furniture part, or as a drawer pull-out guide.
