Description

Die Erfindung betrifft einen Magnetverschluß, insbesondere zur Verwendung als Möbel- und Gehäusebeschlag, mit einem aus einem Kunststoff bestehenden, im allgemeinen schaftförmigen Gehäuse mit mindestens einem in diesem gehaltenen Permanentmagnet und gegebenenfalls mit einem Gegenstück, gemäß dem Oberbegriff der Ansprüche 1 und 4.The invention relates to a magnetic closure, in particular for use as a furniture and housing fitting, with a consisting of a plastic, generally shaft-shaped housing with at least one held in this permanent magnet and optionally with a counterpart, according to the preamble of claims 1 and 4.

Die Türen von Möbeln und Gehäusen, dies gilt insbesondere für die Türen von Badezimmerschränken und Fotokopierergehäusen, werden in zunehmendem Maß nicht mit Schloß und Schlüssel, sondern mit Magnetsystemen verschlossen. Beim Öffnen und Schließen erübrigt dies das Drehen eines Schlüssels. Beim Öffnen einer Tür mit Magnetverschluß muß die Tür lediglich mit geringem Kraftaufwand aus ihrer magnetischen Verriegelung gelöst und dann in bekannter Weise aufgeschwenkt werden. Zum Schließen wird die Tür in Schließstellung geschwenkt. Die Schließbewegung endet unter starker Geräuschbildung beim Anschlagen des Gegenstücks auf dem Permanentmagnet. Wegen der Fangwirkung am Ende des Schließweges unter starker Geräuschbildung werden die hierfür verwendeten Maagnetsysteme auch Magnetschnäpper genannt. Beim Stand der Technik werden die Permanentmagnetsysteme, bestehend aus zwei Stahl-Polplatten mit zwischenliegendem Permanentmagnet, in einem offenen Gehäuse gehalten oder liegen frei und sind damit sichtbar. Auch die Stahl-Gegenstücke liegen frei und sind als solche erkennbar. Zum Unterdrücken dieses von vielen Benutzern als häßlich empfundenen Aussehens werden Magnete bei hochwertigen Möbeln mit einem Furnier überzogen oder mit Spachtel abgedeckt. In der Serienfertigung scheidet ein Überfurnieren wegen der Schwierigkeit dieses Verfahrens sowie der damit verbundenen Kosten aus. Zum Erhalten einer ausreichend hohen Magnet- bzw. Schließkraft muß das Furnier oder die Spachtelschicht sehr dünn gehalten werden. Nur dann kommt die Magnetkraft im letzten Bereich der Schließbewegung noch ausreichend zur Wirkung. Deshalb sind auch diese abgedeckten Maagnete ebenso wie die nicht abgedeckten Magnete mit dem Nachteil behaftet, daß ihre Wirkung unter Geräuschbildung endet.The doors of furniture and housings, this applies in particular to the doors of bathroom cabinets and photocopier housings, are increasingly closed not with lock and key, but with magnetic systems. When opening and closing this eliminates the need to turn a key. When you open a door with magnetic lock the door must be solved only with little effort from its magnetic lock and then swung open in a known manner. To close the door is pivoted in the closed position. The closing movement ends with heavy noise when striking the counterpart on the permanent magnet. Because of the catching effect at the end of the closing path with strong noise, the Maagnetsysteme used for this purpose are also called Magnetschnäpper. In the prior art, the permanent magnet systems, consisting of two steel pole plates with intermediate permanent magnet, held in an open housing or are exposed and are thus visible. The steel counterparts are also free and recognizable as such. To suppress this appearance, which many users find ugly, magnets are covered with veneer or covered with a spatula in high-quality furniture. In series production overfurning is ruled out because of the difficulty of this process and the associated costs. To obtain a sufficiently high magnetic or closing force, the veneer or the filler layer must be very thin being held. Only then does the magnetic force in the last area of the closing movement still have sufficient effect. Therefore, these covered magnets as well as the uncovered magnets have the disadvantage that their effect ends with noise.

Die US 2 987 338 A zeigt einen magnetischen Türverschluß, bei dem der Magnet in einem Gehäuse liegt und metallische Polstücke auf dessen dem Gegenstück gegenüberliegenden Seite angeordnet sind. Bei Schließen der Tür schlagen das Gegenstück und die Polstücke unter Geräuschbildung aufeinander. Die FR 1 273 435 A zeigt einen magnetischen Türverschluß, bei der ein zylinderförmiger Magnet von aus Weicheisen oder einem anderen Metall mit hoher Permeabilität bestehenden ebenfalls zylinderförmigen Elementen umschlossen wird. Ihre Stirnseiten ragen etwas aus dem Türverschluß heraus. Bei Schließen der Tür schlagen sie unter Geräuschbildung auf das Gegenstück auf.US 2 987 338 A shows a magnetic door lock in which the magnet is located in a housing and metallic pole pieces are arranged on its opposite side of the counterpart. When closing the door, the counterpart and the pole pieces hit each other with noise. FR 1 273 435 A discloses a magnetic door lock in which a cylindrical magnet is enclosed by elements also of cylindrical shape made of soft iron or other high permeability metal. Their faces protrude slightly out of the door lock. When the door is closed, they strike the counterpart with noise.

Von diesem Stand der Technik ausgehend liegt der Erfindung die Aufgabe zugrunde, einen Magnetverschluß so auszubilden, daß die magnetische Anziehungskraft während des letzten Teils der Schließbewegung langsamer ansteigt bzw. beim Öffnen langsamer abfällt als beim Stand der Technik. Zusätzlich sollen die beim Auftreffen des Permanentmagneten oder des magnetischen Teils auf das Gegenstück entstehenden Geräusche herabgesetzt oder sogar vermieden werden. Weiter soll das Aussehen verbessert werden.Based on this prior art, the invention has the object, a magnetic closure in such a way that the magnetic attraction increases more slowly during the last part of the closing movement or slows down when opening than in the prior art. In addition, the noise generated when the permanent magnet or the magnetic part impinges on the counterpart should be reduced or even avoided. Next, the appearance should be improved.

Die Lösung für diese Aufgabe ergibt sich bei einem Magnetverschluß der eingangs genannten Gattung nach der Erfindung durch die kennzeichnenden Merkmale der Ansprüche 1 und 4.The solution to this problem arises in a magnetic closure of the type mentioned according to the invention by the characterizing features of claims 1 and 4.

Permanentmagnete aus einem hochenergetischen Magnetwirkstoff mit Anziehungskräften, die bedeutend über denen herkömmlicher Permanentmagnete auf Hartferrit-Grundlage liegen, sind seit einiger Zeit im Handel. Die hohe magnetische Anziehungskraft auch auf Entfernung dieser aus hochenergetischem Magnetwerkstoff bestehenden Permanentmagnete ermöglicht ihre Anwendung in einem durch einen Kopf verschlossenen Schaft oder in einem an seinem Arbeitsende offenen und dort mit einem Kragen versehenen Schaft. Der den Permanentmagneten vollständig abdeckende Kopf und der den Blick auf den Permanentmagneten einschränkende Kragen führen zusätzlich zu dem erwünschten guten Aussehen. Die hohe magnetische Anziehungskraft auch auf Entfernung läßt den sich durch den Kopf oder den Kragen ergebenden größeren Abstand zum Gegenstück zu und bleibt so groß, daß sie in ausreichendem Maße wirksam wird. Der größere Endabstand zwischen Permanentmagnet und Gegenstück auch in der Schließstellung führt zu einem allmählichen Ansteigen und Abfallen der Schließkraft während des letzten Teiles der Wegstrecke. Dies und die Elastizität des den Kopf und den Kragen bildenden Werkstoffs dämpfen die Geräuschbildung praktisch bis auf den Wert Null. Die angestrebten Ziele werden damit mit beiden erfindungsgemäßen Ausführungsformen erreicht.Permanent magnets made of a high-energy magnetic substance with attractive forces, which are significantly higher than those of conventional hard ferrite-based permanent magnets, have been on the market for some time. The high magnetic attraction also on removal of these high-energy magnetic material existing permanent magnets allows their application in a closed by a head shaft or in an open at his working end and there provided with a collar shaft. The permanent magnet completely covering the head and the view of the permanent magnet restricting collar in addition to the desired good appearance. The high magnetic attraction even at a distance leaves the larger distance to the counterpart resulting from the head or the collar and remains so great that it becomes sufficiently effective. The larger end distance between the permanent magnet and counterpart even in the closed position leads to a gradual increase and decrease in the closing force during the last part of the route. This and the elasticity of the material forming the head and the collar virtually dampens the noise to zero. The desired objectives are thus achieved with both embodiments of the invention.

Bei der den Kopf aufweisenden ersten Ausführungsform weist dieser eine ebene Stirnfläche auf oder hat Linsenform. Bei dieser Ausführungsform wird der Permanentmagnet mit etwas Spannung in das offene Ende des Schaftes eingeschoben und an dessen Arbeitsende durch den Kopf gehalten. Bei der zweiten Ausführungsform mit offenem Arbeitsende ist ein Ring in dieses Ende eingelegt. Der Permanentmagnet liegt an diesem Ring an und wird dadurch in seiner Sollage gehalten.In the head having the first embodiment, this has a flat end face or has a lens shape. In this embodiment, the permanent magnet is inserted with some tension in the open end of the shaft and held at the working end by the head. In the second embodiment with open working end, a ring is inserted in this end. The permanent magnet is applied to this ring and is thereby held in its desired position.

Bei der zweiten Ausführungsform steht der Kragen zweckmäßig axial etwas vor. Dadurch wird der gewünschte größere Abstand zum Gegenstück erzielt. Weiter erschwert ein axial vorstehender Kragen den unerwünschten Blick auf das freie Ende des Permanentmagneten.In the second embodiment, the collar is expedient axially slightly before. As a result, the desired greater distance to the counterpart is achieved. Furthermore, an axially projecting collar impedes the unwanted view of the free end of the permanent magnet.

Der erfindungsgemäße, aus einem hochenergetischen Magnetwerkstoff bestehende Permanentmagnet enthält ein Seltenerdmetall. Hierbei handelt es sich um Neodym, das zweckmäßig als Nd2Fe24B, in Form einer Neodymeisenborverbindung, vorliegt.The inventive permanent magnet consisting of a high-energy magnetic material contains a rare earth metal. This is neodymium, which is expediently present as Nd 2 Fe 24 B, in the form of a neodymium iron boron compound.

Bei beiden Ausführungsformen kann der Schaft an zwei sich gegenüberliegenden Stellen unter Bildung von Spreizschlitzen axial geschlitzt sein. Dies erleichtert sein Einschieben in Bohrungen in Türen. Die Elastizität des den Schaft bildenden Kunststoffes führt zu einem Aufweiten des Schaftes in der Bohrung und begünstigt seinen sicheren Halt.In both embodiments, the shaft may be axially slotted at two opposite locations to form spreader slots. This facilitates its insertion into holes in doors. The elasticity of the plastic forming the shaft leads to a widening of the shaft in the bore and favors its secure hold.
