Abstract

The invention relates to a mechanical/magnetic connecting structure, that is to say a mechanical interlock by means of magnetic-force assistance, which is particularly suitable for closures such as those which are used on bags, rucksacks and comparable objects, wherein the connecting structure has the following features: an interlock apparatus having at least one spring interlock element which moves in a direction and is arranged in one of the connecting modules, and having a blocking piece for interlocking of the connecting modules, which blocking piece is arranged in the other connecting module, and having a movable unlocking element with a force-deflecting rising sliding surface, which is likewise arranged in the other connecting module, and a magnet armature structure having at least one magnet which is arranged in one of the connecting modules, and at least one armature which is arranged in the other connecting module.

Description

The invention relates to a mechanical-magnetic connection construction, d. H. a magnetic force assisted mechanical interlock particularly suited for closures used on bags, rucksacks and similar articles, this list is not intended to limit the scope of the invention.

In principle, such connection constructions can be divided into two main groups. There are mechanical connecting structures, the opening and closing mechanism consists of a combination of mostly positive and non-positively acting components. Frequently, springs are used to maintain a locked state so that closing and opening must occur against the spring force. Such connection constructions are known in the art, so that reference is made only to the state of the art from the content of subclasses IPC A44B.

For example, from the document US 5974 637 Plug buckles known in which a spring latching is formed so that a separating element, such as a wedge, with a tapered surface, the latch gradually spreads until it disengages and is released. Closures such as these buckle have by the gradual overcoming of the detent on a soft opening feel, but have an unsatisfactory closing haptics, since they can be closed with considerable force and usually only with two hands.

Another major group of connection constructions are the magnetically-acting connection structures in which the magnetic force is used to hold the connection together. These connection constructions are also well known for closures of bags and other containers of the professional world, so that here too only reference is made to the content of the subclasses of IPC E05C.

Furthermore, combinations between these two main groups are known. In these combinations, it is usually attempted to meet specific requirements for a connection construction by specifically combining the different properties of a mechanical connection and a magnetic connection structure.

In the following, for the sake of better understanding the advantages of the invention, first of all some of the main characteristics of the mechanical and magnetic connection constructions will be discussed.

A positive mechanical lock usually has a mechanical component that is loaded when the lock is loaded to train, pressure or shearing. The size of the mechanical resistance of this component defines the stability of the connection structure. Mechanical connection structures are inexpensive to produce because z. B. in pocket closures only very inexpensive iron parts or plastic parts are used.

In principle, these mechanical connection constructions have the property that a locking spring force has to be overcome manually during mating. Therefore, in some cases, the handling of the connection constructions is not very comfortable, so that use is made of magnetic connection constructions, because they pull themselves together due to the magnetic force.

The force felt when closing and opening on the hand is referred to below as haptic. Especially with closures that are operated by hand, the haptics of the human hand force must be adjusted.

For magnetic connections in which the magnetic force is used directly to prevent the opening of the connection, the magnet and the associated anchor must be dimensioned according to the holding force. If no special requirements are placed on the locking force and the haptics, these connections are in principle applicable.

The closures must be oversized in certain cases, however, if z. B. safety requirements are met. This can z. B. be required in a backpack for mountaineers. This backpack may not open even if the closure is charged with a multiple of the normal locking force, which z. B. may occur in a crash. In this respect, closures are designed with such a requirement profile as mechanical closures, since with mechanical structures and high safety factors can be realized without much additional effort. In this respect, these connection constructions have prevailed on the mass market.

Furthermore, various mechanical connection constructions are known from the prior art in which magnets are used in addition to a mechanical locking. However, the magnets only serve to hold together the mechanical lock in the closed state. The magnetic force is used instead of the spring force of a mechanical spring. These constructions do not have a pleasant feel. They are usually relatively easy to close, but difficult to open.

In the document US 6295702 is a mechanically locked magnetic closure is described in which during the closing magnet and armature pull a mechanical detent that must be unlocked at opening first, before the magnetic closure can be opened.

The opening haptic is unsatisfactory, because during the opening magnet and armature in their Hauptanziehungsrichtung, ie the direction in which they have moved when closing each other, are separated and thus a jerky feel is connected, since the magnetic attraction in the closed position is maximum and after strongly unlinear drops. In addition, the mechanical tumbler secured here by an additional magnet-armature system in the closed position, which is also opened opposite to the magnetic field, so that the feel for unlocking the shutter has a jerky course and is therefore unsatisfactory.

From the document US 6182336 Furthermore, a mechanical tumbler of a magnetic closure is known, which is opened by an inclined surface of a control knob. However, the opening feel is also unsatisfactory here, since during the opening magnet and armature in their Hauptanziehungsrichtung, ie the direction in which they have moved when closing each other, are separated and thus a pronounced jerky feel is connected, since the magnetic attraction in the closed position is maximum and then decreases strongly unlinear.

From the US 4,270,781 is a connecting structure designed as a door opening and closing device, in which two components are displaceable relative to one another in order to hold a door closing in a retracted state of the components and to open the door in an extended state. The connecting structure has a locking device for locking the components to each other in the retracted state, which is realized by a arranged on the one component groove, in which a guided on the other component ball for coupling the components engages and in the retracted state with a Locking portion of the groove in plant is. The connecting structure also has a magnet-armature construction, which is formed by a magnet on the one component and metallic plates on the other component and serves to hold the door in the retracted state of the components magnetically in the closed position. When one component is extended relative to the other component, the magnetic attraction between the magnet and the armature is weakened, thereby reducing the magnetic attraction force on the door so that the door can be opened.

1. a. Verriegelung erfolgt mechanisch,
2. b. Verbindungskonstruktion zieht sich von selbst zusammen,
3. c. Verbindungskonstruktion lässt sich leicht öffnen, d. h. weist eine gute Haptik auf, die
4. d. gleichmäßig, d. h. ruckfrei über den gesamten Bedienweg verläuft.

For the following requirements, no connection construction is known from the prior art:

1. a. Locking is done mechanically,
2. b. Connecting construction contracts by itself,
3. c. Connection construction is easy to open, ie has a good feel, the
4. d. evenly, ie smoothly over the entire operating path runs.

It is therefore the object of the invention to provide a connecting structure that meets all three requirements a to c at the same time.

This object is achieved with a mechanical-magnetic connection construction according to claim 1. This connection construction has two connection modules and serves to connect two elements, to each of which one of the connection modules can be fastened.

• Eine Verriegelungsvorrichtung mit wenigstens einem federnd ausweichenden Federverriegelungselement, das in einem der Verbindungsmodule angeordnet ist,
  wenigstens einem Sperrstück zum formschlüssigen Verriegeln der Verbindungsmodule, das in dem anderen Verbindungsmodul angeordnet ist und einem bewegbaren Entriegelungselement mit einer kraftumlenkenden ansteigenden Gleitfläche. Das Federverriegelungselement ist so ausgebildet, dass es beim Schließen der Verbindungskonstruktion gegen das Sperrstück gedrängt wird. Das Federverriegelungselement, das Sperrstück und die miteinander in Berührung kommenden Flächenabschnitte des Federverriegelungselements und des Sperrstücks sind so ausgebildet, dass das Federverriegelungselement seitlich ausgelenkt wird und schließlich in das Sperrstück einschnappt, wenn sich das Verriegelungselement und das Sperrstück relativ aufeinander zu bewegen. Es ist dem Fachmann klar, dass die Verwendung des Begriffs "Feder" lediglich die Eigenschaft "federnd" beschreiben soll. Demzufolge fallen auch alle Ausführungsformen darunter, bei denen elastische Materialien eingesetzt werden. Es ist weiterhin klar, dass die "federnde" oder die "elastische" Eigenschaft auch dem Sperrstück zugeordnet werden kann.

The connecting structure has the following features:

• A locking device with at least one resiliently deflecting spring locking element, which is arranged in one of the connecting modules,
  at least one locking piece for positive locking of the connection modules, which is arranged in the other connection module and a movable unlocking element with a kraftumlenkenden rising sliding surface. The spring locking element is designed so that it is urged against the locking piece when closing the connecting structure. The spring locking element, the locking piece and the contacting surface portions of the spring locking element and the locking piece are formed so that the spring locking element is deflected laterally and finally snaps into the locking piece when the locking element and the locking piece move relative to each other. It is clear to the person skilled in the art that the use of the term "spring" should only describe the property "resilient". As a result, all embodiments fall under which elastic materials are used. It is also clear that the "resilient" or the "elastic" property can also be assigned to the locking piece.

The locking piece and the locking element are designed so that the mechanical strength is sufficient depending on the actual occurring or possible loads.

• Wenn die Verbindungskonstruktion zusammengeschnappt ist, liegt eine formschlüssige Verbindung vor. Um den Formschluss zu lösen, wird das bewegbare Entriegelungselement verschoben, bis das Federverriegelungselement so weit von der kraftumlenkenden ansteigenden Gleitfläche beiseite gedrängt worden ist, bis das Sperrstück nicht mehr in Eingriff mit dem Federverriegelungselement steht, d. h. das Federverriegelungselement und das Sperrstück werden von der Eingriffsposition in die Nichteingriffsposition gebracht. Dabei ist dem Fachmann klar, dass die Kraft umlenkende ansteigende Gleitfläche nicht notwendigerweise am Ende des Federverriegelungselements anzugreifen braucht, sondern auch an einer anderen, frei wählbaren, federnden Stelle des Federverriegelungselements angreifen kann.

Further, the unlocking member is movable to urge the spring lock member from an engagement position in which the spring lock member is engaged with the lock piece to a disengaged position in which the spring lock member is not engaged with the lock piece. In this case, the kraftumlenkende increasing sliding surface of the spring locking element is designed so that it pushes the spring locking element against the spring force aside during a shift. This combination of features will be explained in more detail below:

• If the connection construction snaps together, there is a positive connection. In order to release the positive engagement, the movable unlocking element is displaced until the spring locking element has been pushed aside by the kraftumlenkenden rising sliding surface until the locking piece is no longer in engagement with the spring locking element is, that is, the spring locking element and the locking piece are brought from the engaged position to the disengaged position. It is clear to those skilled in the art that the force deflecting rising sliding surface does not necessarily need to attack the end of the spring locking element, but can also attack at another, freely selectable, resilient point of the spring locking element.

The connection construction furthermore has a magnet armature construction, wherein the magnet is arranged in one of the connection modules and the armature is arranged in the other connection module. The magnetic force between armature and magnet is chosen so large that during the closing operation, the connecting modules are pulled from a predetermined minimum distance from each other, whereby the spring locking element urges against the locking piece until it snaps into engagement. In other words, magnet and armature are dimensioned so that the spring force of the spring locking element is overcome. It will be clear to those skilled in the art that magnet-armature constructions can not consist of only a single magnet and a single armature. In the following, therefore, a magnet-armature construction will be understood to mean any combination of magnets and armatures which are least of one another, it being known to the person skilled in the art that the armature may consist of a ferromagnetic material or may also be a magnet. Certain magnetic anchor designs not only attract, but can also repel when opposing two magnetic poles of the same name. Unless special additional conditions apply, it does not matter if the magnet is moved relative to the armature or the armature is opposite to the magnet. It is also clear that the interaction between magnet and armature is the same as between two magnet attracting.

When the connection modules are connected, there is a mechanical lock and also a magnetic attraction. It should be noted, however, that magnetic attraction absorbs only a negligible part of the main load of the connection. The magnetic anchor construction almost exclusively serves to automatically close the connection.

Thus, when separating the magnet from the anchor the initially mentioned pleasant, d. H. jerk-free feel, the connection module with the magnet and the connection module with the armature are displaced laterally relative to one another until the magnetic force is sufficiently weakened in order to be able to easily separate the modules by hand. This is the case when the armature surface facing the magnet has become sufficiently small. It is clear that the displacement between the magnet and the armature can also be a twist or a pivot.

The movable magnet is coupled to the unlocking element, i. h., With the magnet and the unlocking element is moved, wherein the term "coupled" not only means that the unlocking element must be rigidly connected to the magnet. A coupling also means a connection via a spring. A coupling is also present when a driver moves the unlocking, but this driver is not always applied to the unlocking, d. h., if there is a game. These relationships are explained in more detail in the description of the embodiments.

• Wenn der Magnet weit genug vom Anker verschoben wurde, sodass die magnetische Anziehungskraft zwischen Anker und Magnet ausreichend schwach ist, ist das Federverriegelungselement allmählich zurückgedrängt worden, d. h., es befindet sich in der Nichteingriffsposition. In dieser Nichteingriffsposition ist die Verbindungsvorrichtung sowohl mechanisch entriegelt, als auch magnetisch gelöst.

Hereinafter, the essential features and properties of the main feature of the invention will be summarized.

• When the magnet has been displaced far enough away from the armature that the magnetic attraction force between the armature and the magnet is sufficiently weak, the spring locking element has been gradually pushed back, that is, it is in the disengaged position. In this disengaged position, the connection device is both mechanically unlocked and released magnetically.

In other words, to open the shutter, the magnetic force is gradually weakened or canceled by the lateral displacement of the magnet and armature with little effort and the spring lock mechanism is gradually opened with little effort. Thus, it is understood that this connecting structure has a particularly soft opening haptics.

It is clear that when closing the connecting structure, the above-described opening position between the unlocking element and the spring locking mechanism and between the armature and the magnet must not be present, i. That is, when closing, the locking piece, the spring locking element and the unlocking must face each other so that it can come to snapping. On the other hand, when closing, the magnet and the armature must face each other in a position in which the magnetic force between the magnet and the armature is strong enough to overcome the spring force of the spring locking element, so that the snap action can take place.

In other words, it must be ensured after opening or at the latest shortly before the closing of the connecting structure that the locking structure and the magnet-armature construction are each returned to their original position, in which the contraction and the snapping are possible. This provision of the functional elements of the locking structure and the magnet-armature construction is effected by return means. All that needs to do is to apply a force to the component to be returned. In the present invention, the force of a return spring is preferably used, which is biased when opening the connecting structure. It is clear to the person skilled in the art that this return spring need only be so strong in order to force the functional elements moved during opening back into their starting position. This only a very small force is required, so that only a weak return spring is required. This is one reason why the aforementioned soft and pleasant feel is retained.

• Wenn ein Anker und ein Magnet aneinander haften, dann kann diese magnetische Haftverbindung gelöst werden, in dem der Anker vom Magneten abgeschoben wird. Wenn die sich anziehenden Flächen von Magnet und Anker gleich groß sind, dann verkleinert sich der anziehende Flächenabschnitt, wenn Anker und Magnet seitlich voneinander abgeschoben werden. Beim Abschieben muss eine Rückstellkraft überwunden werden, denn der Magnet und der Anker werden durch die Magnetkraft in der Ausgangsposition gehalten. Je kleiner die Reibung zwischen den sich anziehenden Flächen ist, um so größer ist die Rückstellkraft. Dieser bekannte Effekt kann noch verstärkt werden, wenn Magnet und Anker bestimmte Formen und/oder Magnetisierungen aufweisen. So ist z. B. klar, dass sich eine dreieckige Ankerfläche bei geeigneter Magnetisierung nach einer näherungsweise gleich großen, ebenfalls dreieckigen Magnetfläche ausrichtet.

However, the provision can also be made by magnetic means. This effect is well-known to the person skilled in the art, so that only one possibility is explained by many:

• If an anchor and a magnet stick together, then this magnetic bond can be released by pushing the anchor off the magnet. If the attracting surfaces of magnet and anchor are the same size, then the attracting surface portion decreases when anchors and Magnet are laterally pushed apart from each other. When pushing off a restoring force must be overcome, because the magnet and the armature are held by the magnetic force in the starting position. The smaller the friction between the attracting surfaces, the greater the restoring force. This known effect can be further enhanced if magnet and armature have certain shapes and / or magnetizations. So z. B. clear that aligns a triangular armature surface with a suitable magnetization for an approximately equal, also triangular magnetic surface.

The technical teaching described above with reference to a sliding movement can analogously apply the expert also to a rotational movement or to a tilting movement, without requiring an inventive step is required.

According to an advantageous embodiment of the invention according to claim 2, the magnet-armature construction on a plurality of locking elements or a locking element with a plurality of locking portions. With this embodiment of the invention, it is z. B. possible to better distribute the attacking load force.

According to an advantageous embodiment of the invention according to claim 3, the magnet-armature construction on a coupling device which has a game in the direction of movement of the movable magnet, so that the unlocking element is pulled by means of a stop only in the direction of the magnet when the game is used up , The advantage of this embodiment is that the displacement of the magnet from the armature can be greater than the distance the unlocking element has to be displaced until the spring locking element is out of engagement with the locking piece. With this embodiment, connecting structures can be built in which the displacement of the magnet from the armature due to structural constraints must be greater than the path that the unlocking element is moved.

According to an advantageous embodiment of the invention according to claim 4, the magnetic anchor construction as a coupling device on a coupling spring whose spring force along the direction of movement of the magnet and the unlocking extends. The advantage of this embodiment is that with this combination of features a security against the opening of the connecting structure has been created under stress. The coupling spring is dimensioned so that in the unloaded state of the mechanical locking device when moving the magnet via the coupling device and the unlocking element is pulled along. In the loaded state, however, the frictional force between the spring locking element and the locking piece is greater than the spring force, ie, the magnet can, for. B. be moved by hand without the mechanical lock opens. If the mechanical lock is relieved in this state, the spring immediately pulls or pushes the unlocking element in the opening direction so that the connection can be opened.

According to an advantageous development of the invention according to claim 5, the magnetic anchor construction on a coupling device which has a game in the direction of movement of the movable magnet, so that the unlocking element is pulled by means of a stop only in the direction of the magnet when the game is used up , Furthermore, a return spring for the unlocking element is provided, whose spring force extends along the direction of movement of the unlocking element. When the magnet is displaced from the armature and the play of the coupling device is used up, the return spring is tensioned. When the connection is released, the magnet and the armature pull in the counter-overlay, and at the same time the unlocking element is urged into its initial position.

From the dependent claims 3 to 5 it can be seen that there are a variety of combinations of this type, in which attacks, drivers and springs are used, but all follow the same technical teaching, so that the skilled person depending on the technical conditions an appropriate Combination without the need for an inventive step. In particular, tension and compression springs can be combined.

According to an advantageous embodiment of the invention according to claim 6 is an operable by hand or with the foot actuator for moving the Magnet or the armature provided, which is movably mounted in one of the two connection modules.

According to an advantageous embodiment of the invention according to claim 7, a hand-tangible object is provided on one of the connection modules, which can be placed by hand on the other connection module. This embodiment of the invention is suitable for. B. for connecting a bicycle lamp with the bicycle handlebar. In this case, the anchor is directly connected to the object in one piece.

According to an advantageous development of the invention according to claim 8, the magnet-armature construction in a connection module at least one magnet and in the other connection module at least one ferromagnetic armature or poled on attraction magnet. This arrangement is preferred when a low cost connection is needed.

According to an advantageous development of the invention according to claim 9, the magnet-armature construction in a connection module on a magnet with two ferromagnetic baffles and in the other connection module on a ferromagnetic armature, wherein the baffles are arranged so that they are in magnetic operative relationship with the ferromagnetic armature and the magnet does not touch the anchor. This arrangement is preferred when a robust connection is required, because in this magnetic anchor construction no mechanical contact of the magnetic surface with the surface of the armature occurs, so that damage to the sensitive magnetic surface z. B. is avoided when repeated shifting, even if foreign objects such. B. sand in between.

According to an advantageous embodiment of the invention according to claim 10, the magnet-armature construction in a connection module on a magnet with a ferromagnetic baffle and in the other connection module on a ferromagnetic armature, wherein the magnet and the baffle are arranged so that they are in magnetic operative relationship with the ferromagnetic anchor stand. This arrangement is preferred when the magnetic force is particularly good to be exploited, which is achieved by the bundling of the magnetic field lines in the magnetic guide plate.

According to an advantageous development of the invention according to claim 11, the magnet-armature construction in each connection module on a magnet with ferromagnetic baffles, wherein the baffles in the closed position are attractive. This arrangement is preferred when a robust connection with a high tightening force is required in the closed state, and when at least low repulsion is desired when opening.

According to an advantageous development of the invention according to claim 12, the magnet-armature construction at least two each opposite magnets, which are both in a closed position of the connection in a tightening position and in the open position in a repelling position. This arrangement is preferred when a connection with high tightening force in the closed state and high repulsion force is required when opening.

According to an advantageous embodiment of the invention according to claim 13, the magnet-armature construction has a magnet arrangement in which in each connection module, a magnet and a ferromagnetic armature are arranged so that in the closed state, the magnets are in opposition to the armature and are polarized so that in the open state, the magnets are polarized on repulsion. This arrangement is preferred when a cost-effective connection with high tightening force in the closed state and low repulsion force is required when opening.

According to an advantageous embodiment of the invention according to claim 14, the unlocking element in addition to the kraftumlenkenden rising sliding surface, which brings the spring locking element out of engagement with the locking piece, a second sliding surface, which after urging the spring locking element in the disengaged position, the force of the tensioned spring locking element in a Ejection force between the first connection module and the second connection module deflects to eject the first connection module from the second connection module. It is clear to the person skilled in the art that the ejection force arises when either the spring locking pieces were urged from a straight position to an oblique position and the resulting skew the spring tension of the spring locking element has been partially converted into an ejection force, insofar as the second sliding surface allows sliding with low friction of the elements to each other, or if the unlocking presses with the second sliding surface on a slope on the spring locking element or an obliquely formed second sliding surface on the unlocking with the spring locking element interacts or combinations of the aforementioned possibilities, which convert by means of known to those skilled chamfers and sliding surfaces, the spring tension at least partially into an ejection force.

With the schematic representation in Fig. 1 a to 1e the general function of the invention will be described. Fig. 1 f shows a special function.

The reference symbols 1 and 2 designate the connection modules to be connected, which are separated by a dividing line 3 for the sake of clarity. Both connection modules are thus separated, d. H. spaced opposite.

The connection module 1 consists of a magnet 4, a locking piece 5 and an unlocking element 40 with a kraftumlenkenden portion 40 a. The Unlocking element 40 is connected via a coupling device 7 with the magnet 4.

The connecting module 2 consists of a ferromagnetic armature 8 and a spring locking element 9, which has a locking piece 9a and a spring portion 9b. When the movable connection module 2 approaches the fixed connection module 1 from below, ie in the direction of the arrow A, then a position is lost Fig. 1b reached.

In this position, the locking piece 9a is located on the locking piece 5 with an engagement surface 9c, which may be tapered. By means of the magnetic force F between the magnets 4 and 8, the resiliently held locking piece 9a is urged against the lower edge of the locking piece 5. The magnetic force F and the spring constant of the spring portion 9b are so dimensioned that the spring portion 9b springs back in the direction of the arrow, so that a position after Fig. 1c is reached.

In this intermediate position, the locking piece 9a has been pushed back in the direction of the arrow. When it has reached the upper edge of the locking piece 5, the spring portion 9b urges the locking piece 9a in the in Fig. 1d shown arrow direction.

In this position, the magnetic surface and the armature surface are in contact or close to each other, and the locking piece 9a now lies on the surface of the locking piece 5, d. h., the lock is snapped shut. It is thus no longer possible, the connection module 2 down, d. H. in loading direction B, as the lock prevents this.

It should be emphasized that the magnetic force has no significant influence on the strength of the connection.

1. a. Das Federverriegelungselement 9 wird über die Kopplungsvorrichtung verschoben, sodass das Verriegelungsstück 9a durch die kraftumlenkende ansteigende Gleitfläche 40a des Entriegelungselements 40 soweit zurückgedrängt wird, bis das Verriegelungsstück 9a und das Sperrstück 5 nicht mehr in Eingriff stehen.
2. b. Durch die seitliche Verschiebung des Magneten 4 tritt eine erhebliche Schwächung der Magnetkraft F ein, sodass der Anker 8 nicht mehr oder nur noch schwach von dem Magneten angezogen wird.

The release of the connection modules 1 and 2 from each other is in Fig. 1 e shown. For this purpose, the magnet 4 is pushed off laterally in the direction of arrow C from the armature 8. This performs two functions:

1. a. The spring locking element 9 is moved over the coupling device, so that the locking piece 9a is pushed back by the kraftumlenkende rising sliding surface 40a of the unlocking element 40 until the locking piece 9a and the locking piece 5 are no longer engaged.
2. b. By the lateral displacement of the magnet 4 occurs a significant weakening of the magnetic force F, so that the armature 8 is no longer or only weakly attracted by the magnet.

These two functions cause a haptic pleasantly soft opening of the connection, since the at least greatly weakened magnetic force F, the otherwise so typical for magnetic locks jerky separation does not occur.

It is clear to the person skilled in the art that it is equivalent whether, as in Fig. 1e ' shown, the locking piece 5 is fixedly arranged in the connection module 1 and only the unlocking element 40 is moved, or whether the locking piece and the unlocking element, as in Fig. 1e shown, are made in one piece and moved together.

Fig. 1z and Fig. 1z 'show the separate connection modules with movable or fixed locking piece.

After disconnecting the connection modules, the magnet-armature arrangement reverts to the starting position by means of suitable measures which are still to be described Fig. 1a It should be noted here that an automatic reset already takes place due to the magnetic property. One skilled in the art will appreciate that the degree of recovery depends on a number of factors, with friction between the magnet and the armature being a significant factor.

Hereinafter, the coupling device 7 will be explained. The coupling device 7 is a rigid or an elastic connection between the magnet 4 and the locking piece 5. However, the coupling device 7 may also be a partially fixed and loose connection, ie a connection with a game.

First, it is assumed that the coupling device 7 is a rigid connection. In this case, the magnet 4, the coupling device 7 and the locking piece 5 are to be regarded as an integral body. As a result, the force application point of the displacement force Fv is arbitrary. In the Fig. 1e the displacement force Fv acts on the magnet 4.

If the coupling device 7 is a tension spring, then the force application point is no longer freely selectable, ie the force application point for the displacement force Fv must be selected on the magnet 4, as in Fig. 1f shown.

In Fig. 1f a particular general embodiment of the invention is shown, which in conjunction with the Fig. 1e will be explained below. The coupling device 7 is a tension spring. Out Fig. 1e It can be seen that with the displacement of the magnet 4 and the displacement of the locking piece 5 is carried out. In Fig. 1f the connected connection modules 1 and 2 are under tensile stress in the loading direction B, ie the locking piece 5 and the locking piece 9a of the spring locking element 9 are pressed against each other. This surface pressure of the superposed surface portions prevents the unlocking element 40 from being pulled by the tension spring in the direction of the displaced magnet. Thus, there is a safety lock that can not be opened under load, since only the magnet 4 is displaced. The unlocking element 40 is blocked because the frictional force is greater than the spring force of the tension spring.

Fig. 1g - 1i show a further particular advantageous development of the invention. Show Fig. 1g '- 1i' the same stages as Fig. 1g - 1i from a different perspective. Fig. 1g shows the closure in the closed state accordingly Fig. 1d , New is in Fig. 1h in that the unlocking element 40 has a second sliding surface 40b which is urged against the locking piece 9a when it is opened. The second sliding surface 40b and the locking piece 9a have such a geometry that, as in FIG Fig. 1i shown, the spring tension of the tensioned locking spring 9b is deflected in an ejection force in the arrow direction. This is particularly advantageous in closures that have a magnetic anchor system that still has a weakened residual tightening force in the open position. By the Tuning the spring force of the locking spring 9b on the Restanziehung in opening position between magnet 4 and armature 8, and by means of a suitable geometry of kraftumlenkenden portion 40b and the slope of the locking piece 9c, the ejection force in the direction of arrow be dimensioned so that this residual tightening force between the magnet 4 and armature 8 is overcome and the shutter opens automatically.

Finally, the Fig. 1c ' explained. It is clear to the person skilled in the art that the function of the spring section 9b can also be taken over by the locking piece 5 if the locking piece 5 can yield elastically in the direction of the arrow by means of a spring section 5a. Also, a combination is possible, that is, it is both a spring portion 9b, and a spring portion 5a provided. Thus, the shows Fig. 1c ' the same functional stages as the Fig. 1 c.

The previous versions of the coupling device concerned the rigid and the elastic coupling device. If the coupling device is a connection with a game, the function can not with the Fig. 1 be explained. For this purpose, the following figures are used.

The Fig. 2a - b show a special coupling device 7. Since the general function of the invention already in Fig. 1 has been described, not all functional phases are shown graphically below. The Fig. 2a shows a closed connection construction, ie, this functional phase 2a corresponds to the functional phase in Fig. 1d ,

The magnet 4 is connected via a coupling device 7 with the unlocking element 40. The coupling device 7 has a clearance 7d along the direction of movement of the magnet when opening. From the Fig. 2 It can be seen that a coupling engagement piece 7c, which is firmly connected to the unlocking element 40, engages in a coupling recess 7b. The coupling recess 7b is longer than the coupling engagement piece 7c, so that a coupling play 7d is formed. In the Fig. 2a is the coupling engaging piece 7c at the left end of the coupling recess 7b. When the magnet 4 is displaced in the arrow direction, the coupling plate 7a moves with the coupling recess 7b also in this direction until the Coupling engagement piece 7c at the right end of the coupling recess 7b is applied, ie, the coupling play 7d was passed through without the locking piece 5 moves. If the magnet is moved even further, the unlocking element 40 is pulled along, so that, as out Fig. 1e is known, the locking piece 9a is pushed by the kraftumlenkenden rising sliding surface 40a of the unlocking member 40 aside until the disengaged position is reached. Thus, the connection structure is opened, since both the positive locking is released, and the tightening force between the magnet 4 and the armature 8 is weakened or greatly weakened. This results in a haptic pleasant opening behavior when the connecting structure is opened by hand. By appropriate measures, a provision is made in the starting position Fig. 2a ,

The advantage of this coupling devices with a game is that the magnet-armature construction can be built so that a particularly soft feel results in particularly strong attractive magnet-armature systems chosen by the distance of the displacement of the magnet 4 is particularly long is while at the same time the distance of the displacement of the unlocking element 40 may be smaller and less friction occurs here. This can be z. B. are advantageously used for a closure in which several narrow spring locking elements, which cause a uniform tumbler, to be unlocked simultaneously.

The Fig. 3a - b show another special coupling device 7. The general function has already been after Fig. 1 described, and the special effect of a paddock with play was after Fig. 2 described. In Fig. 3 the coupling recess 7b is much longer. In addition, a return spring 10 is coupled to the unlocking element 40, which is stretched when moving the magnet 4 when the coupling play 7 d is used up. After opening the connecting structure, ie after unlocking, the unlocking element return spring 10a pulls the unlocking element 40 back again.

The advantage of this coupling devices with play is a very reliable return to the closed position, regardless of the magnetic return.

This coupling device is used for example for safety belt fasteners.

The Fig. 4a - b show another special coupling device 7. The general function has already been after Fig. 1 described, and the special effect of a paddock with play was after Fig. 2 described. In addition, a magnet return spring 10 b is coupled to the magnet 4, which is compressed when moving the magnet 4. After opening the connecting structure, ie after unlocking, the magnet return spring 10b pushes the magnet back over the coupling device 7 and thus also the unlocking element 40 again when the coupling play 7d has been used up.

The advantage of this coupling devices with game is that when approaching the modules, the magnets are always in the position of maximum attraction and thus pull each other particularly effective. This coupling device is used for poorly accessible closures that should attract optimal.

The Fig. 5a - c show another special coupling device 7. The general function has already been after Fig. 1 described and the special effect of a paddock with play was after Fig. 2 described. This connection construction relates to a safety function against opening under load, as already in Fig. 1f described. The Fig. 5a shows the closed connection structure under load, ie, the locking piece 9a is pressed in the direction of arrow on the locking piece 5. Between the locking piece 5 and the magnet 4, a magnetic unlocking-coupling spring 10c is arranged. If the magnet 4 after Fig. 5b shifted in the direction of the arrow, the magnet-unlocking element-coupling spring 10c expands, while the unlocking element 40 is held in position by means of the locking piece 9a. When the loading force B is eliminated, the magnetic unlocking element coupling spring 10c pulls the locking piece 5 to the left so that the locking piece 9a is urged by the unlocking member to the disengaged position. The pushing back of the unlocking element 40 to the right via the left end portion of the coupling recess 7b.

The advantage of this coupling devices with play is that opening under load is prevented. These coupling devices are used, for example, for secured closures of loaded straps, ropes, ropes, etc., as required for mountaineering or yachting needs.

Below are the schematic diagrams of the Fig. 1 to 5 described in specific embodiments. As far as possible, it is indicated in the specific embodiments, on which the schematic diagrams of Fig. 1 to 5 the particular embodiment concerned is based.

It is clear to those skilled in the art that the movements of the magnet and the unlocking element 40 and the other elements is not limited to a straight-line movement. However, the rectilinear motion is best suited for explanation, so that for the description of the schematic diagram of the invention in the Fig. 1 to 5 the straight-line movement was chosen. It is also clear to the person skilled in the art that there are a large number of variants with regard to the arrangement of coupling devices and their design, solely by the combination of the variants shown, so that a person skilled in the art can find suitable combinations or modifications as needed without himself being inventive have to.

In the following embodiments, the movement of the magnet is rectilinear.

The Fig. 6 shows a closure for bags or satchels. The Fig. 6a shows a perspective view of the essential components of the closure. 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. On the type of mounting options will not be indicated in the following embodiments, since it is clear to the skilled person how such products are attached. The connection module 1 is designed as a plug with a longitudinally extending wedge-shaped plug-in section 11. In the plug portion 11 is a fixed locking piece 5 and the plug with the eleventh integrally formed unlocking element 40 with the kraftumlenkenden rising sliding surfaces 40a1, 40a2, 40a3, 40a4 provided. 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 following views.

The Fig. 6b and FIG. 2 c show two sectional views AA-1, AA-2 and BB-1, BB-2, respectively, from which it can be seen how the two connection modules unlock. In the sectional view AA-1 and BB-1 are the spring locking element 9a1 and 9a2 on the locking pieces 5 and 5 'on. This corresponds to the functional phase in Fig. 1d , In the sectional view AA-2 and BB-2, the spring locking elements 9a1 and 9a2 are already bent back from the kraftumlenkenden rising sliding surfaces 40a1 and 40a3. This corresponds to the functional phase in Fig. 1e ,

From the longitudinal sections CC-1 and CC-2 in Fig. 6d the position of the magnets 4a and 4b and armature 8a and 8b of ferromagnetic material can be seen. It will be understood by those skilled in the art that the armatures 8a and 8b may also be magnets. The position of the magnets 4a and 4b and the armatures 8a and 8b is to be determined by the person skilled in the art so that in the illustrated sectional view CC-1 the two connection modules are contiguous, ie, either two attracting magnets or a magnet and an armature have to be face. If z. B. magnets 4a and 4b also anchor magnets 8a and 8b attractively facing, then the magnets 4a and b and the armature magnets 8a and b are poled ungleichnamig. When the magnets 4a and b and the armature magnets 8a and b are shifted from each other, then two magnetic poles of the same name face each other, which cause a repulsion, which is described in the separation of the connection modules.

Fig. 7 shows an embodiment of the invention as a buckle. Fig. 7a shows a perspective view of the buckle in the closed state comparable Fig. 1 d. The connection module 2 is designed as a plug 2, which has a belt seat 64 and is inserted into the housing 1a. In the housing 1a, the rocker arm 1b is tiltably mounted via the stub axles 62a, b in the axle bearings 63a, b. About the operating lever 50, the rocker arm can be tilted.

Fig. 7b shows the sectional view C - C of the closed buckle analogous to Fig. 1d , In the plug 2, the armature 8 is arranged in the rocker arm 1b, the magnet 4 is arranged. Both are attractive in the closed position. A positive connection between connection module 1 and 2 is about the locking of the locking pieces 9a1, 2 with the locking pieces 5a, b. The locking pieces are firmly connected to the housing 1a.

Fig. 7f shows the buckle in phase analogous to Fig. 1e , Here, the kraftumlenkenden rising sliding surfaces 40a1, 2 of the unlocking the locking pieces 9a1, 2 far enough against the spring force of the locking springs 9b1, 2 pushed back that the locking pieces 9a1, 2 are out of engagement with the locking pieces 5a, b and the form-fitting is released. In the right view of Fig. 7f It can be seen that the magnet 4 and the armature 8 are tilted against each other and the magnetic attraction is correspondingly weakened, so that the buckle is also released magnetically to open.

It is also in Fig. 7f corresponding Fig. 1h the ejection support drawn according to claim 15. In the shifted state, the sliding surfaces 40b1, 2 of the unlocking mechanism and / or the chamfers 9c1, 2 of the spring locking mechanism cooperate so that the spring tension of the springs 9b1,2 is deflected into an ejection force of the plug 2 from the housing 1a.

The Fig. 8 shows a closure for strap ends on backpacks or bags or for holding an ice pick. In this closure, the two connection modules 1 and 2 are no longer linearly shifted from each other, but rotated concentrically to each other.

The Fig. 8a shows the essential components except magnet and armature in an exploded view. The rotary member 1b for receiving the magnets 4a, b (not shown) has a locking member 5 formed as a peripheral edge fixedly connected to the rotary member and also fixedly connected unlocking members 40 with the rising sliding surface 40a. The rotary part 1b is in the first connection module 1a rotatably mounted. It is rotated with the operating lever 50, which is firmly connected during assembly with the rotary member 1b.

The spring locking element 9 is designed particularly soft resilient and thus offers a particularly soft feel while stable mechanical locking by the Querzug on the locking pieces 9a1, 2. The spring locking element 9 is annular, wherein the ring forms the spring portion 9b. In contrast, two locking pieces 9a1 and 9a2 are connected to the ring, that is, the spring locking element 9 is integrally formed. At the locking pieces 9a1 and 9a2 is ever a bevel 9c, which is identical to the bevel 9c from the Fig. 1 , The locking pieces 9a1, 9a2 are movably mounted in the recesses 12a, b in the second connecting module 2.

Fig. 8b shows the position of the cutting plane BB. Fig. 8d shows the sectional view BB-1, in which the closed closure is shown. Here, when closing the locking pieces 9a1, 9a2 pushed by the locking piece 5 aside and are drawn here behind the locking piece 5 locked.

Fig. 8c shows the sectional view BB-2, in which the shutter in the actuated state analogous to Fig. 1e is drawn. Here, the locking pieces 9a1, 9a2 have been pushed aside from the force deflecting rising sliding surfaces 40a1, 40a2 of the unlocking member 40 so that the locking pieces 9a1, 9a2 and the locking piece 5 are disengaged.

In addition, show Fig. 8c and 8d the arrangement of the magnet-armature system. The magnets 4a, 4b are rotatably mounted in the connection module 1a together with the rotary part 1b. The armature magnets 8a and 8b are fixedly arranged in the connection module 2. In the closed state, the magnets 4a, 4b and the armature magnets 8a, 8b face each other so that in Fig. 8d opposing poles attractively facing each other or ever an anchor and a magnet are attractively opposed. In Fig. 8c the magnets 4a, 4b have been moved, and there are at least two poles of the same name opposite, so that the closure is pushed open by the magnetic force.

Fig. 8e shows in sectional view AA-1 again the closed position analog Fig. 1d and in sectional view AA-2, the shifted position after Fig. 1e in that the force deflecting rising sliding surfaces 40a1, 40a2 have urged the locking pieces 9a1, 9a2 into disengaged position.

After these detailed explanations, it has become apparent that further embodiments of the invention are possible by the connecting modules either in rotation, tilting or sliding, either shifted against each other as a whole or be moved against each other via an actuator, ie magnet or armature in a connection module are movably mounted. In addition, it will be apparent to those skilled in the art that various magnet systems that repel in the translated state may be used. Finally, it is clear to the person skilled in the art that there are very different arrangements for the locking piece 5. The locking piece 5 may be fixedly connected to the movable in connection module 1 a magnet 4, as in the embodiment according to Fig. 8 shown. Alternatively, the locking piece 5 can be firmly connected to the connection module 1a, while the magnet is movably mounted in the connection module 1a, as in the embodiment according to FIG Fig. 7 is shown.
