Description

Die Erfindung betrifft einen Magnetverschluss zum Verschließen von vorzugsweise Handtaschen und vergleichbaren Gegenständen. Derartige Verschlüsse sind aus dem Stand der Technik zum Beispiel aus der US 2002/0000024 A1 oder der US 2004/0244419 A1 hinreichend bekannt, in denen eine mechanische Verriegelung für einen Magnetverschluss bzw. eine magnetisch unterstützte Verriegelung für eine Verschlussvorrichtung beschrieben werden.The invention relates to a magnetic closure for closing preferably handbags and similar items. Such closures are known from the prior art for example from US 2002/0000024 A1 or the US 2004/0244419 A1 well-known in which a mechanical lock for a magnetic closure or a magnetically assisted lock for a closure device are described.

Diese Verschlüsse weisen jedoch eine unbefriedigende Haptik auf, weil auf Grund des stark nichtlinearen Verlaufs der magnetischen Anzugskraft ein Öffnen des Verschlusses von Hand meist nur ruckartig erfolgen kann. Es ist daher ein beständiges Bedürfnis, die Öffnungs- und Schließeigenschaften derartiger Verschlüsse zu verbessern, wobei zusätzlich zu beachten ist, dass Magnetverschlüsse so ausgebildet sein müssen, damit Daten auf Kreditkarten nicht gelöscht werden.However, these closures have an unsatisfactory haptic, because due to the strong non-linear course of the magnetic attraction opening of the closure by hand can usually be done only jerky. It is therefore a continuing need to improve the opening and closing properties of such closures, in addition to the fact that magnetic locks must be designed so that data on credit cards are not deleted.

Es besteht daher die Aufgabe der Erfindung darin, einen Magnetverschluss bereitzustellen, der eine zuverlässige Funktion und eine angenehme Haptik aufweist und zudem die auf der Kreditkarte gespeicherten Daten nicht löscht.It is therefore the object of the invention to provide a magnetic closure, which has a reliable function and a pleasant feel and also does not delete the data stored on the credit card.

Diese Aufgabe wird mit einem Magnetverschluss nach Anspruch 1 gelöst. Ein Magnetverschluss mit zwei Verbindungsmodulen zum Verbinden von zwei Elementen, an denen jeweils eines der Verbindungsmodule befestigbar ist, weist in jedem der Verbindungsmodule wenigstens einen Permanentmagneten auf. Weiterhin ist an jedem Verbindungsmodul ein rohrförmiger Führungsabschnitt angeordnet. Der Begriff rohrförmig ist nicht auf einen kreisförmigen Querschnitt beschränkt ist. Der Querschnitt kann eine frei wählbare symmetrische oder unsymmetrische Form haben. Es kommt lediglich darauf an, dass die Führungsabschnitte ineinander steckbar ausgebildet sind. Die gleichen Bedingungen gelten für rinnenförmige Führungsabschnitte.This object is achieved with a magnetic closure according to claim 1. A magnetic closure with two connection modules for connecting two elements, to each of which one of the connection modules can be fastened, has at least one permanent magnet in each of the connection modules. Furthermore, a tubular guide section is arranged on each connection module. The term tubular is not limited to a circular cross-section. The cross section may have a freely selectable symmetrical or asymmetrical shape. It is only important that the guide sections are plugged into each other. The same conditions apply to channel-shaped guide sections.

Die Permanentmagnete sind am Boden der Führungsabschnitte angeordnet, wobei in dem ersten Führungsabschnitt der Permanentmagnet fest angeordnet ist und in dem zweiten Führungsabschnitt der Permanentmagnet so bewegbar angeordnet ist, dass sich der Permanentmagnet beim Schließen selbsttätig in eine Anzugsposition zu dem anderen Permanentmagneten ausrichtet.The permanent magnets are arranged at the bottom of the guide portions, wherein in the first guide portion of the permanent magnet is fixedly disposed and movable in the second guide portion of the permanent magnet, that the permanent magnet automatically aligns when closing in a tightening position to the other permanent magnet.

Die Erfindung weist folgende Vorteile auf:
Durch die ineinander steckbaren Führungsabschnitte lässt sich der Verschluss bequem zusammenfügen. Da die Magnete innerhalb der Führungsabschnitte angeordnet sind, kann eine magnetfeldempfindliche Kreditkarte nicht beschädigt werden. Beim Zueinanderziehen der Magnete entsteht für den Menschen ein gewünschtes haptisches Gefühl. Dieses Gefühl vermittelt den Eindruck, dass sich der Verschluss automatisch und sicher schließt. Beim Öffnen entsteht auch ein gewünschtes haptisches Gefühl. Dieses Gefühl vermittelt den Eindruck, dass sich der Verschluss scheinbar von selbst öffnet, da die magnetischen Abstoßungskräfte die Module angenehm weich trennen - im Gegensatz zu dem ruckartigen Öffnen, wie es von den meisten Verschlüssen dieser Art aus dem Stand der Technik bekannt ist. Damit der erfindungsgemäße Magnetverschluss funktioniert, muss eine technische Maßnahme vorgesehen werden, damit die beim Öffnen entstehenden magnetischen Querkräfte aufgefangen werden. Diese Querkräfte werden von den ineinander steckenden Führungsabschnitten aufgenommen. Insofern haben diese Führungsabschnitte eine Doppelfunktion, d. h. sowohl als Abstandshalter für die Kreditkarte, als auch als Widerlager gegen die magnetischen Querkräfte, die beim Öffnen entstehen.The invention has the following advantages:
The plug-in guide sections make it easy to assemble the closure. Since the magnets are disposed within the guide portions, a magnetic field sensitive credit card can not be damaged. When the magnets are pulled together, a desired haptic feeling is created for humans. This feeling gives the impression that the closure closes automatically and safely. When opening also creates a desired haptic feeling. This feeling gives the impression that the shutter seems to open by itself, as the magnetic repulsion forces make the modules pleasantly soft-unlike the jerky opening known from most prior art closures of this type. In order for the magnetic closure according to the invention to function, a technical measure must be provided so that the magnetic transverse forces arising during opening are absorbed. These transverse forces are absorbed by the nested guide sections. In this respect, these guide sections have a double function, ie both as a spacer for the credit card, as well as an abutment against the magnetic transverse forces that arise when opening.

Nach Anspruch 2 weisen die Führungsabschnitte Anschrägungen oder Abrundungen auf, um das Ineinanderstecken zu erleichtern.According to claim 2, the guide portions chamfers or rounded to facilitate nesting.

Nach Anspruch 3 weisen die Führungsabschnitte ein Spiel auf, um das Ineinanderstecken zu erleichtern.According to claim 3, the guide portions on a game to facilitate nesting.

Nach Anspruch 4 ist neben dem Permanentmagnet wenigstens ein ferromagnetischer Anker so angeordnet, dass im Schließzustand der Permanentmagnet an einem ferromagnetischen Anker anliegt und beim Öffnen die Permanentmagnete in eine Abstoßungsposition bewegbar sind.According to claim 4, in addition to the permanent magnet at least one ferromagnetic armature is arranged so that in the closed state of the permanent magnet bears against a ferromagnetic armature and when opening the permanent magnets are movable in a repulsion position.

Nach Anspruch 5 bestehen die Führungsabschnitte aus ferromagnetischem Material, wodurch eine weitere Abschirmung des Magnetfeldes bewirkt wird, so dass die Gefahr einer Beschädigung von Kreditkarten noch weiter gesenkt wird.According to claim 5, the guide portions are made of ferromagnetic material, whereby a further shielding of the magnetic field is effected, so that the risk of damage to credit cards is further reduced.

Nach Anspruch 6 haben die Führungsabschnitte einen kreisförmigen Querschnitt. Damit lassen sich besonders einfache Konstruktionen herstellen.According to claim 6, the guide portions have a circular cross-section. This makes it possible to produce particularly simple constructions.

Nach Anspruch 7 ist an dem bewegbaren Magneten eine Rückstellvorrichtung vorgesehen. Diese Rückstellvorrichtung erleichtert die Bedienung des Verschlusses.According to claim 7, a return device is provided on the movable magnet. This return device facilitates the operation of the closure.

Nach Anspruch 9 ist die Rückstellvorrichtung ein auf Abstoßung gepolter Magnet. Diese Ausführungsform weist eine besonders gute Haptik auf.According to claim 9, the restoring device is a poled on repulsion magnet. This embodiment has a particularly good feel.

Nach Anspruch 10 ist die Rückstellvorrichtung ein Gewicht, das in einer vorbestimmten räumlichen Ausrichtung des Magnetverschlusses auf Grund der Gewichtskraft den bewegbaren Magneten in seine Ausgangsposition drückt. Diese Ausführungsform ist besonders kostengünstig.According to claim 10, the return device is a weight which presses the movable magnet in its initial position in a predetermined spatial orientation of the magnetic closure due to the weight force. This embodiment is particularly inexpensive.

Die Erfindung wird nachfolgend an Hand eines Ausführungsbeispiels und anhängenden Zeichnungen näher erläutert:

The invention will be explained in more detail below with reference to an embodiment and attached drawings:
Fig. 1

Ausgehend von Fig. 1 und 2 weist die Erfindung ein verpolbares Magnetsystem auf, das bei Drehung durch Magnetkraft schließt oder öffnet. Erfindungsgemäß sind die Magnete am Boden rohrförmiger Führungsabschnitte angeordnet. In der Schnittdarstellung sind die Magnete mit N und S gekennzeichnet. In der Position c stehen sich gleichnamige Pole gegenüber, so dass sich der Verschluss von selbst öffnet, d. h. das Oberteil wird in Pfeilrichtung abgestoßen. Es ist aus den Zeichnungen entnehmbar, dass in der Position a die Magnete in einem Abstand x von der Oberkante der rohrförmigen Führungsabschnitte versenkt sind. Dieser Abstand ist so bemessen, dass Kreditkarten nicht beschädigt werden. Weiterhin ist entnehmbar, dass die Führungsabschnitte an ihren Oberkanten leicht gerundet sind, so dass sie gut ineinander passen. Wenn der Magnetverschluss verschlossen ist, liegen die rohrförmige Führungsabschnitte in entsprechenden Ausnehmungen des jeweiligen Gegenstücks, damit die sich anziehenden Magnete dicht beieinander liegen können.Starting from Fig. 1 and 2 the invention has a poled magnet system which closes or opens upon rotation by magnetic force. According to the invention, the magnets are arranged on the bottom of tubular guide sections. In the sectional view, the magnets are marked with N and S. In the position c, poles of the same name face each other, so that the closure opens by itself, ie the upper part is repelled in the direction of the arrow. It can be seen from the drawings that in the position a, the magnets at a distance x from the upper edge of the tubular guide portions sunk. This distance is calculated so that credit cards are not damaged. Furthermore, it can be seen that the guide sections are slightly rounded at their upper edges, so that they fit well together. When the magnetic closure is closed, the tubular guide portions lie in corresponding recesses of the respective counterpart, so that the attracting magnets can be close to each other.

Fig. 3 zeigt die Ausführungsform nach Fig. 1 in der Schnittansicht mit einer Federrückstellung, die mittels einer Rückstellfeder RF bewirkt wird, um den Verschluss in seine Ausgangslage zurückzustellen. Fig. 3 shows the embodiment according to Fig. 1 in the sectional view with a spring return, which is effected by means of a return spring RF, to return the closure to its original position.

Fig. 4 zeigt die Ausführungsform nach Fig. 1 in der Schnittansicht mit einer Magnetrückstellung, die mittels Rückstellmagnete bewirkt wird, um den Verschluss in seine Ausgangslage zurückzustellen. Fig. 4 shows the embodiment according to Fig. 1 in the sectional view with a magnet reset, which is effected by means of return magnets to return the shutter to its original position.

Fig. 5 zeigt die Ausführungsform nach Fig. 1 in der Schnittansicht mit einer gravimetrischen Rückstellung, die mittels eines Gewichts bewirkt wird, um den Verschluss in seine Ausgangslage zurückzustellen. Diese Ausführungsform wird dort angewendet, wo eine definierte räumliche Einbaulage gegeben ist, wie z. B. an einem Schrank. Fig. 5 shows the embodiment according to Fig. 1 in the sectional view with a gravimetric reset, which is effected by means of a weight to return the closure to its original position. This embodiment is applied where a defined spatial installation position is given, such. B. on a cabinet.

Die Fig. 6 zeigt einen Verschluss mit einer geradlinigen Öffnungsbewegung. Die Fig. 6a zeigt eine perspektivische Ansicht der wesentlichen Bestandteile. Der Verschluss besteht aus den Verbindungsmodulen 1 und 2, die an der Tasche befestigt werden. Grundsätzlich kann die Befestigung auf verschiedene Art und Weise erfolgen, z. B. durch Annähen, Kleben, Vernieten oder Verschrauben. Auf die Art der Befestigungsmöglichkeiten wird in den nachfolgenden Ausführungsformen nicht weiter hingewiesen, da dem Fachmann klar ist, wie derartige Produkte befestigt werden. Das Verbindungsmodul 1 ist als Stecker mit einem sich längs erstreckenden keilförmigen Steckabschnitt 11 ausgebildet. In dem Steckabschnitt 11 ist ein feststehendes Sperrstück 5 mit einer Lücke 6 ausgebildet. Das Federverriegelungselement 9 ist separat dargestellt und wird in die Federverriegelungselement- Aufnahme-Öffnung 12 in Pfeilrichtung eingesetzt. Die Magnete sind in den nächsten Ansichten gezeigt.The Fig. 6 shows a closure with a rectilinear opening movement. The Fig. 6a shows a perspective view of the essential components. The closure consists of the connection modules 1 and 2, which are attached to the bag. In principle, the attachment can be done in various ways, for. B. by sewing, gluing, riveting or screwing. The nature of the mounting options is not further specified in the following embodiments, since it is clear to the person skilled in the art how such products are fastened. The connection module 1 is designed as a plug with a longitudinally extending wedge-shaped plug-in section 11. In the plug portion 11, a fixed locking piece 5 is formed with a gap 6. The spring locking element 9 is shown separately and is inserted into the spring locking element receiving opening 12 in the arrow direction. The magnets are shown in the next views.

Die Fig. 6b zeigt zwei Schnittansichten A-A, aus denen ersichtlich ist, wie sich die beiden Verbindungsmodule verriegeln. In der Schnittansicht A-A-1 liegt das Federverriegelungselement 9 an dem Sperrstück 5 auf. Das entspricht der Funktionsphase in Fig. 1b. In der Schnittansicht A-A-2 ist das Federverriegelungselement 9 bereits zurückgebogen. Das entspricht der Funktionsphase in Fig. 1c.The Fig. 6b shows two sectional views AA, showing how the two connection modules lock. In the sectional view AA-1, the spring locking element 9 rests against the locking piece 5. This corresponds to the functional phase in Fig. 1b , In the sectional view AA-2, the spring locking element 9 is already bent back. This corresponds to the functional phase in Fig. 1c ,

Aus dem Längsschnitt B - B ist die Lage der Magneten und Anker aus ferromagnetischem Material erkennbar. Dem Fachmann ist klar, dass die Anker 8 ebenfalls Magnete sein können. Die Lage der Magnete und der Anker ist vom Fachmann so zu bestimmen, dass sich in der dargestellten Schnittansicht B- B die beiden Verbindungsmodul aneinanderziehen, d. h. es müssen entweder zwei sich anziehende Magnete oder ein Magnet und ein Anker sich gegenüber stehen. Wenn z. B. den Magnete 4a und 4b ebenfalls Magnetanker 8a und 8b anziehend gegenüber stehen, dann sind die Magnete 4 und die Magnetanker 8 ungleichnamig gepolt. Wenn die Magnete 4 und die Magnetanker 8 zueinander verschoben werden, dann stehen sich zwei gleichnamige Magnetpole gegenüber, die eine Abstoßung bewirken, was beim Trennen der Verbindungsmodule beschrieben wird.From the longitudinal section B - B, the position of the magnets and armature made of ferromagnetic material can be seen. The skilled person will appreciate that the armatures 8 can also be magnets. The position of the magnets and the armature is to be determined by a person skilled in the art such that in the illustrated sectional view B-B, the two connecting modules are pulled together, ie. H. There must be either two attracting magnets or a magnet and an anchor facing each other. If z. B. the magnets 4a and 4b also magnet armature 8a and 8b are attractively opposite, then the magnets 4 and the magnet armature 8 are poled ungleichnamig. If the magnets 4 and the armature 8 are shifted from each other, then there are two magnetic poles of the same name, which cause a repulsion, which is described in the separation of the connection modules.

Die Fig. 6c zeigt die gleiche Darstellung wie Fig. 6b, jedoch ist aus der Schnittansicht A-A erkennbar, dass das Federverriegelungselement 9 mit dem Sperrstück 5 verriegelt ist. Somit ist die Verbindung geschlossen. Es ist zu erwähnen, dass sich das Federverriegelungselement 9 in dem Abstützbereich 13 vollflächig abstützt und bei Belastung der Verbindungskonstruktion fast ausschließlich auf Druck belastet wird, wodurch eine sehr hohe Stabilität der Verbindungskonstruktion entsteht.The Fig. 6c shows the same representation as Fig. 6b However, it can be seen from the sectional view AA that the spring locking element 9 is locked with the locking piece 5. Thus, the connection is closed. It should be mentioned that the spring locking element 9 is fully supported in the support region 13 and is loaded almost exclusively under pressure when the connecting construction is loaded, resulting in a very high stability of the connection construction.

Die Fig. 6d zeigt die Öffnungsphase, bei der das Verbindungsmodul 2 nach links verschoben ist. Damit liegt das Federverriegelungselement 9 in der Lücke 6 und ist somit nicht mehr in Eingriff. Gleichzeitig wurde durch die Verschiebung des Moduls 2 auch die Magnet-Anker-Konstruktion 4/8 verschoben. In dieser Fig. 6d ist gezeigt, dass hinter den Magneten noch Magnetleitplatten angeordnet sind, Diese dienen in diesem Beispiel zur verbesserten Ausnutzung der Magnetkraft durch den Kurzschluss der hinten austretenden magnetischen Feldern und schirmen den Tascheninhalt wie z.B. Kreditkarten gegen unerwünschte Magnetfelder ab.The Fig. 6d shows the opening phase in which the connection module 2 is shifted to the left. This is the spring locking element 9 in the gap 6 and is thus no longer engaged. At the same time, the magnet-armature construction 4/8 was moved by the displacement of the module 2. In this Fig. 6d Magnetic plates are shown behind the magnets, these serve in this example, the improved utilization of magnetic force by the short circuit of the rear exiting magnetic fields and shield the pocket contents such as credit cards against unwanted magnetic fields.

Aus den Zeichnungen ist ebenfalls entnehmbar, dass die Magnete versenkt angeordnet sind und die Führungsabschnitte so ausgebildet sind, dass die Verschlusshälften gut zusammenfügbar sind.It can also be seen from the drawings that the magnets are arranged sunk and the guide sections are formed such that the closure halves can be easily joined together.
