Description

The invention relates to a mechanical-magnetic connection construction, d. H. Connection construction with a mechanical locking by means of magnetic force support, this connecting construction is particularly suitable for closures, as used on bags, backpacks and similar items. However, this list does not limit the scope of the invention.

Depending on their application, a great variety of requirements are made of these manually operated closures.

So there are z. For example, the requirement that the closure itself be blocked under load. To achieve this requirement, such closures have undercuts or bevels and are designed so that a positive locking is formed when the closure is loaded in the intended loading direction. To close the closure, the closure halves to be joined are moved in the closing direction to each other and then usually hung together.

The following explanations relate to closure halves which are to be closed and which are biased, d. H. on the closure halves is a force that acts opposite to the closing direction.

For interlocking the shutter halves are brought into a closed position in which they are moved towards each other via a suspension point. Depending on the depth of the undercut, the shutter halves move during hanging a smaller or larger path opposite to the bias. To open, these closure halves must be moved again opposite this path to the bias to disengage the closure halves, ie to overcome the undercut. The shutter halves are therefore harder to solve under bias than without bias. When notching or unhooking, it is often necessary to move the shutter halves slightly sideways. These movements are usually not registered by humans, because the human hand copes with such movements easily. However, if the functionality of the hand is limited, for. B. because of a Illness, or when a ski glove is worn, the movement sequences in opening and closing become very important, especially when closing when closing on at least one half of a fastener force against which the human hand force has to work.

The requirement that the closure can not or only with difficulty be opened under load has thus been achieved by means of the above-described interlocking with the undercuts, but only at the price that the closure under pretensioning closes just as hard as it opens.

But there is also the requirement that the closure should be closed comfortably under load. This can z. B. be achieved by z. B. a buckle in addition to the mechanical lock also contains a magnetic anchor construction. This ensures that the closure halves contract by themselves and thus the manual force is supported by the magnetic tightening force.

Such closures can often open jerky again, because when opening the magnetic force must be overcome. However, in a number of applications it is desired that the closure should also be very comfortable and easy to open so that even persons wearing thick gloves or limited in hand motor skills can easily open the closure when the closure is unloaded.

From the prior art a variety of closure structures are known, but always meet only a part of the requirements described above.

This is how the documents describe WO2008 / 006357 A2 and WO2009 / 010049 A2 two locking constructions that are very easy to close and open, but do not provide secure locking under load. As a result, such a closure can accidentally burst under load, which must be avoided in safety-relevant requirements. With these two Closure constructions are achieved or assisted by magnetic force closure.

In the document EP 0 907 331 B1 is described a closure construction for jewelry, in which the normal load is also absorbed by a positive mechanical connection. Furthermore, magnets are provided which cause some help in closing. This magnetic closure opens under load heavier than without load, since the closure halves are hung as described above, one inside the other and when unmounting a piece to each other must be moved. However, it closes when closing under load just as hard as it must be moved by the depth of the undercut against the load. In addition, it must also be partially worked against the magnetic force. Depending on the structural design of such magnetic fasteners, a more or less jerky separation of the magnet from the armature occurs, which impairs the opening feel of the closure.

• Selbsttätiges oder sehr leichtes Schließen ohne Belastung
• Schließkraftunterstützung beim Schließen unter Belastung
• Sichere Verriegelung unter Belastung
• Sehr einfaches Öffnen ohne Belastung

From the range of different requirement profiles of the opening and closing behavior of closures that are opened and closed by hand, the following requirement profile from the prior art has not yet become known:

• Automatic or very easy closing without load
• Closing force assistance when closing under load
• Safe locking under load
• Very easy opening without load

It is the object of the invention to provide a closure which fulfills the requirement profile described above.

This object is achieved with the closure structures according to the invention according to claim 1 and 2.

According to claim 1, a mechanical-magnetic connection construction on two connection modules for connecting two elements. At each of the elements in each case one of the connection modules can be fastened. The attachment takes place at the load receiver of the connection module. The load absorption z. As in a buckle, the slot-shaped openings in which the straps are threaded to secure the straps to the buckle. The connection modules can already be loaded when closing with a load F _L , ie the connection modules must be z. B. are contracted by hand against the force generated by the load before they engage and lock.

The force direction of the load F _L is substantially in the direction of the connecting line between the load receptacles, ie, in a buckle assembly, the direction of force on a line in the direction of two strained straps whose end portions are connected by means of the buckle.

The connection modules have the following features: a locking device for positive locking of the connection modules, wherein the locking device has a spring locking element which is arranged in the first connection module. In the second connection module a matching locking piece is arranged.

There is provided a magnet armature construction having a first magnet disposed in one of the connection modules and an armature or a second magnet disposed in the other connection module.

Furthermore, a displacement track is formed in the first connection module, on which the locking piece of the second connection module can be displaced from a closed position, ie a locked state, into an open position, ie into an unlocked state.

• Beim Öffnen werden die Verbindungsmodule von der Schließposition in die Offenposition auf der Verschiebebahn verschoben, wobei der erste Magnet und der Anker oder der zweite Magnet gegeneinander verschoben werden, sodass eine allmähliche Abschwächung der gegenseitigen magnetischen Anziehung eintritt.

The locking device, the magnet-armature construction and the sliding track are in operative connection by the following features:

• When opening the connection modules are moved from the closed position to the open position on the sliding track, wherein the first magnet and the armature or the second magnet are shifted against each other, so that a gradual weakening of the mutual magnetic attraction occurs.

At the same time, the locking piece and the spring locking element on the sliding track are shifted so far against each other in this shift until the spring locking element enters a recess provided for this purpose on the locking piece and thus is no longer in engagement with the locking piece, without the spring locking element is pushed aside.

When closing the connection modules lock by means of the locking device in contrast to the subject of EP 0 907 331 B1 directly into the closed position, wherein the locking piece pushes the spring locking element against a spring force of the spring locking element aside until it engages.

At the same time, when closing, the magnet-armature construction pulls the connection modules towards each other, whereby the locking of the locking device is at least supported.

According to the spatial position of the load receptacles on the connection modules and the spatial position and the shape of the displacement track are chosen and designed so that when moving the connection modules from the closed position to the open position, the load receptacles of the connection modules must move towards each other by an amount Δx. This opening movement takes place against the load F _L , so that a physical work
W = F _L x Δx is necessary. Thus, the connection structure under the load F _{L can be opened} heavier than without the load F _L.

Thus, the object of the invention has been achieved. The connecting construction closes automatically without load or very easily, since the magnetic force strongly supports the closing movement. Furthermore, the connection construction closes comfortably due to the magnetic closing force support even under load. Under load, a very secure locking takes place, which is greater, the greater the force of the attacking load. And without load, the connection construction can be opened very easily.

According to claim 2, a mechanical-magnetic connection construction on two connection modules for connecting two elements. At each of the elements in each case one of the connection modules can be fastened. The attachment takes place at the load receiver of the connection module. The load-carrying in a buckle are the slot-shaped openings into which the straps are threaded to attach the straps to the buckle. The connection modules can already be loaded when closing with a load F _L , ie, the connection modules must, for. B. are contracted by hand against the force generated by the load before they engage and lock.

The force direction of the load F _L is substantially in the direction of the connecting line between the load receptacles, ie, in a buckle assembly, the direction of force on a line in the direction of two strained straps whose end portions are connected by means of the buckle.

The connection modules have the following features: a locking device for positive locking of the connection modules, wherein the locking device has a spring locking element which is arranged in the first connection module. In a second connection module, a matching locking piece is arranged. In addition, a kraftumleitende bevel is provided in the second connection module.

There is provided a magnet armature construction having a first magnet disposed in one of the connection modules and an armature or a second magnet disposed in the other connection module.

Furthermore, a displacement track is formed in the first connection module, on which the locking piece of the second connection module from a closed position, d. H. a lock state, in an open position, d. H. is displaceable in an unlocked state.

• Beim Öffnen werden die Verbindungsmodule von der Schließposition in die Offenposition auf der Verschiebebahn verschoben, wobei der erste Magnet und der Anker oder der zweite Magnet gegeneinander verschoben werden, sodass eine allmähliche Abschwächung der gegenseitigen magnetischen Anziehung eintritt.

The locking device, the magnet-armature construction and the sliding track are in operative connection by the following features:

• When opening the connection modules are moved from the closed position to the open position on the sliding track, wherein the first magnet and the armature or the second magnet are shifted against each other, so that a gradual weakening of the mutual magnetic attraction occurs.

At the same time, the locking piece and the spring locking element are displaced on the sliding track against each other in this shift, wherein the spring locking element is pushed so far aside by the kraftumleitende slope until the spring locking element is no longer in engagement with the locking piece.

When closing the connection modules snap by means of the locking device in contrast to the subject of EP 0 907 331 B1 directly into the closed position, wherein the locking piece pushes the spring locking element against a spring force of the spring locking element aside until it engages.

At the same time, when closing, the magnet-armature construction pulls the connection modules towards each other, whereby the locking of the locking device is at least supported.

According to the invention here, as in claim 1, the spatial position of the load receptacles on the connection modules and the spatial position and the shape of the sliding track are chosen and designed so that when moving the connection modules from the closed position to the open position, the load receptacles of the connection modules to a Amount Δx must move towards each other. This opening movement takes place against the load F _L , so that a physical work W = F _L x Δx is necessary. Thus, the connection structure under the load F _{L is} harder to open than without the load F _L.

In order to explain the technical teaching on which the invention is based, this teaching is first of all shown on the basis of abstract drawings, since this principle is contained in all subsequent concrete closure constructions.

The interaction of the closure halves when closing and opening the closure and the spatial positions of the essential functional elements present are described. Furthermore, the forces acting on closing and opening, ie, when connecting and disconnecting the shutter halves, are described and the physical work involved in connecting and disconnecting is described. For a better understanding, the technical teaching of the invention is compared with the technical teaching, the closure construction of the above EP 0 907 331 B1 underlying.

in diagram form constructive and also functional features of a hook-shaped closure during closing and opening and

Fig. 11a-c

the subject of the invention according to claim 1 and claim 2.

The teaching according to the invention is first explained in comparison with reference to the functions and effects which correspond to a magnetic closure according to the prior art EP 0 907 331 B1 occur.

The FIGS. 10a to 10c show in diagram form constructive and also functional features of a hook-shaped closure during closing and opening. This closure contains in each connection module 1 and 2 each have a magnet 48 and 80 and closure means, which are formed as a tongue 74 and socket 38.

Fig. 10a shows from left to right in two movement sections, the physical work that must be used when closing the shutter under load.

Starting from an idle state, first the connection _module 2 is raised against a downward force F _L from a disconnection position to a height P0, for which the work W _{Δy is} necessary. The height P ₀ is the height position that the connection module 2 has also in the suspended state. Since the magnetic force supports this lifting somewhat, the actual work to be applied W is _Δy minus W _mag1 , see the lower double arrow on the left. The force F _L is the force that has to be overcome when closing under load in order to mount the closure.

In the next movement step, the connection module 2 is further raised so that it faces the recess of the connection module 1. This distance traveled on lifting is indicated by Δx. In order to cover this distance Δx, a work W _{Δx is} required. In addition, as far as possible approached magnets are removed again from each other. For this purpose also a work is required, which denotes W _mag2 and complicates the closing additional. It should be noted that the stronger the downward force F _L , the more difficult it is to close this shutter. However, especially at the critical moment of hooking the connection module 2, the magnetic force also impedes the threading process.

For completeness, the closed position and the opening operation of the closure will be described.

The Fig. 10b shows the closed position of the closure, in which the connection module 2 is lowered to the height Po.

The Fig. 10c shows the opening of the shutter, wherein the connection module 2 against the load F _L must be lifted by Δx.

In contrast to the technical teaching known from the prior art described above, the closure according to the invention closes more comfortably, in particular under load, which will be explained below.

Analogous to the Fig. 10a to 10c Now, the technical teaching of the invention based on the Fig. 11a to 11c explained. For a better understanding, the difference in the work to be done when closing is first described.

Fig. 11a shows the work to be done to close the shutter. The connection module 2 is in a position in which the magnetic force begins to act. Although the connection module 2 is pulled down by the applied force F _L , the magnetic force assists the upward movement of the connection module 2 against the load F _L until it snaps into the closed position Po. For this, the work W _Δy must be done. Due to the magnets 4 and 8 simultaneously acts the magnetic force between these magnets and makes a work W _magnet . As a result, the actual work W _Δy to be performed is reduced by the work W _magnet applied by the magnetic force.

The Fig. 11b shows the closure in the closed position Po, ie the connection modules 1 and 2 are snapped, ie locked together by means of a spring locking device. When locking the spring locking element 9 is pressed against the locking piece 5, wherein the spring locking element 9 is pushed aside so far, until it snaps behind the locking piece 5. Die Federverriegelungsseinrichtung 9 ist mit dem Sperrstück 5 verbunden. Since this spring locking device is known from the introductory state of the prior art, can be dispensed with a more detailed description.

Unlike in the FIGS. 10a to 10c Prior art, the closure according to the invention was closed without the application of additional work. Consequently, this closure closes according to the object of the invention even under load comparatively easier and more comfortable since only a straight-line movement is required for locking and no complicated suspension movement.

It will be explained below that this closure also solves the problem of being difficult to open under load.

The Fig. 11c shows the opening process. For this purpose, the connection module 1 and connection module 2 is displaced on a displacement track 60a, whereby the locking device is disengaged. The position of the load receptacles 51, 51 and the position and shape of the displacement track 60a are chosen according to the technical teaching of the invention such that during this opening displacement of the connection modules the load receptacles 51, 52 were moved toward each other against the force FL by the distance Δx, so that a work W _Δx had to be done for this. The larger the load F _L , the greater the work required, ie the shutter opens heavier with load than without load.

The Fig. 11a to 11c describe both the subject matter of the invention according to claim 1 and according to claim 2.

The functionality has been shown here by means of an oblique displacement track (60a), but as the following exemplary embodiments show, the technical teaching of the invention can also be implemented by curved tracks.

Fig. 1a-e each show in plan view, sectional view AA and perspective view of a linear push-sliding buckle according to the invention for straps according to claims 1 and 3 in the main phases of movement during opening and closing. According to claim 3, the sliding track is formed obliquely. The load receptacles 51, 52 are formed here for the reception of straps and are referred to below Gurtbandaufnahmen 51, 52. Other features are renamed in this and in the following embodiment depending on the embodiment, but provided with the same reference numerals, if this is the understanding of the embodiment.

Fig. 1a shows a linear push-sliding buckle plug 1 and housing 2 with the Gurtbandaufnahmen 51 and 52, wherein the plug and housing are separated from each other. They are now mated in the direction X against the force F _L , which acts in the direction of the connection line between the Gurtbandaufnahmen. This connecting line is identical in the figure with the section line AA. In the plug, a magnet 4 and an anchor or a second magnet 8 is provided in the housing. Due to the magnetic attraction plug 1 and housing 2 are contracted in the X direction, the magnetic force thus supports the closing under load. On the plug attached locking pieces 5a, 5b and attached to the housing spring locking elements 9, 9 'together form a snap lock.

Fig. 1b shows the linear push-in buckles during engagement. The locking lugs 9a, 9b of the spring locking elements are pushed aside by the locking pieces against the spring force of the spring locking elements until they engage.

Fig. 1c shows the linear push-sliding buckles after locking in the closed position. Next, the plug 1 is displaced relative to the housing 2 for opening on an inclined displacement track 60a in an opening direction Y. The oblique displacement track 60a is inclined relative to the horizontal H (perpendicular to load F _L ) by the angle alpha, in other words: the angle between load F _L and opening direction Y is greater than 90 °.

• Magnet 4 und Anker oder zweiter Magnet 8 wurden allmählich voneinander abgeschert, wodurch eine angenehme, subjektiv kaum Kraft erfordernde Haptik erzielt wird,
• Die Sperrstücke 5a, 5b und den Federverriegelungselemente 9, 9' wurden soweit seitlich gegeneinander verschoben, dass sie außer Eingriff gelangt sind, ohne dass das Federverriegelungselement 9, 9' beiseite gedrängt wurde, d.h., der Rastverschluss wurde ohne zusätzlichen Kraftaufwand geöffnet,
• Erfindungsgemäß wurde das Verbindungsmodul 1 auf der schrägen Verschiebebahn 60a so verschoben, dass es um einen Betrag delta x entgegen der Last F_L gezogen wurde. Hierfür war eine von der Last abhängig Kraft nötig, d.h. die linear-Steck-Schiebeschnalle ist unter Last schwerer zu öffnen, als ohne Belastung. Je größer alpha ist, desto schwerer ist die linear-Steck-Schiebeschnalle unter Last zu öffnen. Es sind also verschiedene Variationen denkbar: bei einer linear-Steck-Schiebeschnalle für den Gebrauch an Rucksäcken etc. wird der Winkel alpha= ca. 10°-20° ausreichend für eine Sicherung der Schnalle unter Last sein. Der Winkel alpha kann für den Gebrauch an Sicherheitsausrüstung wesentlich größer gewählt werden.

Fig. 1d and Fig. 1e show the linear push-sliding buckles after the shift to the open position. The displacement caused three functions:

• Magnet 4 and armature or second magnet 8 were gradually sheared off from each other, whereby a pleasant, subjectively little force-requiring feel is achieved,
• The locking pieces 5a, 5b and the spring locking elements 9, 9 'have been shifted so far laterally against each other that it comes out of engagement are, without the spring locking element 9, 9 'was pushed aside, ie, the snap closure was opened without additional effort,
• According to the invention, the connection module 1 has been displaced on the oblique displacement path 60a such that it has been pulled counter to the load F _L by an amount delta x. This required a load-dependent force, ie the linear push-in slide buckle is harder to open under load than without load. The larger alpha is, the harder the linear push-in buckle is to be opened under load. There are therefore various variations conceivable: in a linear push-sliding buckle for use on backpacks, etc., the angle alpha = about 10 ° -20 ° be sufficient for securing the buckle under load. The alpha angle can be much larger for use on safety equipment.

In Fig. 7 is shown a development of the linear push-sliding buckles.

• Fig. 2a zeigt die getrennte bogenförmige, beidseitig zu öffnende bogenförmige Steck-Schwenkschnalle, bestehend aus Stecker 1 und Gehäuse 2 mit den Gurtbandaufnahmen 51 und 52, wobei Stecker und Gehäuse sich voneinander getrennt gegenüberstehen. Sie werden nun gegen die Kraft F_L zusammengesteckt, die gebrauchsmäßig in Richtung der Verbindungslinie zwischen den Gurtbandaufnahmen wirkt. Diese Verbindungslinie ist in der Figur identisch mit der Schnittlinie A-A. Im Stecker ist ein Magnet 4 und im Gehäuse ein Anker oder ein zweiter Magnet 8 vorgesehen. Durch die magnetische Anziehung werden Stecker 1 und Gehäuse 2 in Richtung X zusammengezogen, die Magnetkraft unterstützt also das Schließen unter Last. Am Stecker angebrachte Sperrstücke 5a, 5b und am Gehäuse angebrachte Federverriegelungselemente 9, 9' bilden zusammen einen Rastverschluß.

Fig. 2a-e each show in plan view, sectional view AA and perspective view of an arcuate plug-swivel buckle for straps in the main phases of movement during the opening and closing according to claims 1, 6, 7:

• Fig. 2a shows the separate arcuate, double-sided opening arcuate plug-swivel buckle, consisting of connector 1 and housing 2 with the Gurtbandaufnahmen 51 and 52, wherein the plug and housing are separated from each other. They are now plugged against the force F _L , which acts in the direction of the line connecting the Gurtbandaufnahmen. This connecting line is identical in the figure with the section line AA. In the plug, a magnet 4 and an anchor or a second magnet 8 is provided in the housing. Due to the magnetic attraction plug 1 and housing 2 are contracted in the X direction, the magnetic force thus supports the closing under load. On the plug attached locking pieces 5a, 5b and attached to the housing spring locking elements 9, 9 'together form a snap lock.

Fig. 2b shows the arcuate plug-swivel buckle during engagement. The locking lugs 9a, 9b of the spring locking elements are pushed aside by the locking pieces against the spring force of the spring locking elements until they engage.

Fig. 2c shows the arcuate plug-swivel buckle after locking in the closed position. Next, the plug 1 is displaced relative to the housing 2 for opening on a circular arc-shaped displacement track 60b in an opening direction Y. In this embodiment, the trajectory according to claim 6 has two open positions, which are obtained by displacement in the direction Y or Y '

• Die Sperrstücke5a, 5b und den Federverriegelungselemente 9, 9' wurden soweit seitlich verschoben, dass sie außer Eingriff gelangt sind, ohne dass das Federverriegelungselement 9, 9' beiseite gedrängt wurde, d.h. der Rastverschluss wurde ohne zusätzlichen Kraftaufwand geöffnet,
• Nach Anspruch 7 ist am Stecker ein Gurtband 98 angebracht und Gurtband und Stecker sind als eine steife konstruktive Einheit betrachtet worden, was bei gebräuchlichen modernen dicht gewebten Gurtbändern aus Kunststoff zulässig ist. In diesem Ausführungsbeispiel nach Anspruch 7 liegt der Mittelpunkt der kreisbogenförmigen Verschiebebahn 60b außerhalb des Steckers 1 und auf der Verbindungslinie zwischen den Lastaufnahmen. Das Gurtband 98 muss eine größere Länge als den Radius der Verschiebebahn haben, damit das belastete Ende 51a oberhalb des Mittelpunktes M liegt.

Fig. 2d shows the arcuate plug-swivel buckle after the shift to the open position. The displacement caused three functions:

• Magnet 4 and armature or second magnet 8 were gradually sheared off from each other, whereby a pleasant, subjectively little force-requiring feel is achieved,
• The locking pieces 5a, 5b and the spring locking elements 9, 9 'have been displaced laterally so far that they have been disengaged without the spring locking element 9, 9' being pushed aside, ie the snap fastener was opened without additional effort,
• According to claim 7, a webbing 98 is attached to the plug and webbing and plug have been considered as a rigid structural unit, which is allowed in common modern tight woven webbings made of plastic. In this embodiment according to claim 7, the center of the circular arc-shaped displacement track 60b is outside the plug 1 and on the connecting line between the load receptacles. The webbing 98 must have a greater length than the radius of the displacement track, so that the loaded end 51a is above the center point M.

Fig. 2e shows how the plug 1 has been moved on the arcuate displacement track 60b so that the loaded end 51a of the webbing 98 has been pulled by an amount delta x against the load F _L. For the shift in the direction of Y was dependent on the load force required, ie the arcuate plug-swivel buckle is more difficult to open under load than without load, provided that the length of the webbing and the radius of the movement track have been selected accordingly.

Fig. 2e shows this delta x compared to the closed position and open position.

• Fig. 3a zeigt die geöffnete bogenförmige Steck-Schwenkschnalle, bestehend aus Stecker 1 und Gehäuse 2 mit den Gurtbandaufnahmen 51 und 52, wobei Stecker und Gehäuse sich voneinander getrennt gegenüberstehen. Sie werden nun in Richtung X gegen die Kraft F_L zusammengesteckt, die gebrauchsmäßig in Richtung der Verbindungslinie zwischen den Gurtbandaufnahmen wirkt. Diese Verbindungslinie ist in dieser Figur identisch mit der Schnittlinie A-A. Im Stecker ist ein Magnet 4 und im Gehäuse ein Anker oder ein zweiter Magnet 8 vorgesehen. Durch die magnetische Anziehung werden Stecker 1 und Gehäuse 2 in Richtung X zusammengezogen, die Magnetkraft unterstützt also das Schließen unter Last.

Fig. 3a-e each show in plan view, sectional view AA and perspective view of a further embodiment according to the invention of an arcuate plug-in buckle for straps in the most important phases of movement during the opening and closing according to claims 1, 5, 6:

• Fig. 3a shows the open arcuate plug-swivel buckle, consisting of connector 1 and housing 2 with the Gurtbandaufnahmen 51 and 52, wherein the plug and housing are separated from each other. They are now mated in the direction X against the force F _L , which acts in the direction of the connection line between the Gurtbandaufnahmen. This connecting line is identical in this figure with the section line AA. In the plug, a magnet 4 and an anchor or a second magnet 8 is provided in the housing. Due to the magnetic attraction plug 1 and housing 2 are contracted in the X direction, the magnetic force thus supports the closing under load.

On the plug attached locking pieces 5a, 5b and attached to the housing spring locking elements 9, 9 'together form a snap lock.

Fig. 3b shows the arcuate plug-swivel buckle during engagement. The locking lugs 9a, 9b of the spring locking elements are pushed aside by the locking pieces against the spring force of the spring locking elements until they engage.

Fig. 3c shows the arcuate plug-swivel buckle after locking in the closed position. Next, 1 is shifted relative to the housing 2 for opening on the circular-arc movable track 60b in an opening direction Y. In In this embodiment, the trajectory according to claim 6 has two open positions, which are obtained by displacement in the direction Y or Y '

• Magnet 4 und Anker oder zweiter Magnet 8 wurden allmählich voneinander abgeschert, wodurch eine angenehme, subjektiv kaum Kraft erfordernde Haptik erzielt wird,
• Die Sperrstücke 5a, 5b und den Federverriegelungselemente 9, 9' wurden soweit seitlich verschoben, dass sie außer Eingriff gelangt sind, ohne dass das Federverriegelungselement 9, 9' beiseite gedrängt wurde, d.h. der Rastverschluss wurde ohne zusätzlichen Kraftaufwand geöffnet,

Nach Anspruch 5 liegt der Mittelpunkt M der Verschiebebahn 60b in diesem Ausführungsbeispiel innerhalb des Steckers 1, der Mittelpunkt (M) liegt auf der Verbindungslinie zwischen den Lastaufnahmen und die Gurtbandaufnahme 51 liegt oberhalb des Mittelpunkts M. Für die Verschiebung der Gurtbandaufnahme 51 um delta x war eine von der Last F_L abhängig Kraft nötig, d.h. die bogenförmige Steck-Schiebschnalle ist unter Last schwerer zu öffnen als ohne Last.

Fig. 3d and Fig. 3e shows the arcuate plug-swivel buckle after the shift to the open position. The displacement caused three functions:

• Magnet 4 and armature or second magnet 8 were gradually sheared off from each other, whereby a pleasant, subjectively little force-requiring feel is achieved,
• The locking pieces 5a, 5b and the spring locking elements 9, 9 'have been displaced laterally to the extent that they have been disengaged, without the spring locking element 9, 9' was pushed aside, ie the snap lock was opened without additional effort,
• The plug 1 has been moved so far on the arcuate displacement track 60b that the Gurtbandaufnahme 51 by an amount delta x was pulled against the load F _L. According to claim 5 is the midpoint M of the displacement track 60b in this embodiment, within the connector 1, the midpoint (M) lies on the connecting line between the load receptacles and the Gurtbandaufnahme 51 is above the center M. For the displacement of the Gurtbandaufnahme 51 by delta x was a force dependent on the load F _{L is} necessary, ie the curved push-pull buckle is harder to open under load than without load.

Fig. 3e shows the delta x compared to the closed position and open position.

Depending on how strong the arcuate plug-swivel buckle should be secured under load, one will choose the radius of the displacement track 60b and the distance of the webbing seat 51 from the center M accordingly.

Fig. 4 shows a development of the invention Fig. 3a-e , Here is the release of the locking piece until very late, although magnet 4 and anchor 8 have already been sheared off each other. In the present embodiment, the release takes place only after a rotation of 180 °. The locking piece is completely formed and only interrupted by the release gap 66. With a rotation of about 180 °, the opening can be supported by the reversed magnet 4 in the plug 1 by suitable arrangement of the magnets.

Fig. 5a-d show a linear plug-sliding buckle with opening by kraftumleitende surface according to claim 2. It differs from the execution Fig1a-e only by the different opening according to the preambles of claims 1 and 2. It is therefore only on the of Fig. 1 entered different opening.

The force-diverting, bevelled surfaces 70a, 70b are arranged on the plug, and the force-deflecting, bevelled surfaces 71a, 71b are arranged on the spring-locking elements of the housing 2. The force deflecting surfaces 71a, 71b are not necessarily functionally necessary, but improve the function.

Fig. 5a shows in plan view and sectional view AA a linear plug-sliding buckles of plug 1 and housing 2 in a separate position.

Fig. 5b shows the plug and Fig. 5d shows the housing in different views, respectively, for a better understanding of the position of the force-redirecting beveled surfaces 70a, b and 71a, b.

Fig. 5c shows the of Fig. 1c different opening: by the kraftumlenkenden surfaces 70a, b 71a, b is displaced during the displacement of plug from closed position in the open position in the direction Y gradually the spring locking element, that is, it is compared to the version after Fig. 1 a certain additional effort required to solve the linear push-slide buckles. This is advantageous if the opening of the linear plug-sliding buckles should be difficult, for example in security applications.

Fig. 6a-g show a frontal sliding buckle, which unlike Fig. 1 perpendicular to the load F _L in the direction X closes according to claims 1 and 3.

Fig. 6f and 6g show an exploded view from below or above.

In the plug 1, a magnet 4 is arranged. He is covered with a decorative cap 62. On the plug, a locking piece 5a is arranged as a circumferential edge around a cylinder 65, beveled edge, which forms a latching closure with a spring ring 9 arranged in the housing. On the plug a webbing receiver 52 is arranged. In the housing 2, the spring ring 9 is arranged with a circumferential detent 9a. It is held centered in the housing with an inner stop 63 of a cap 61. On the housing, a webbing receiver 51 is provided. About an oblique displacement track 60a, which is directed at an angle alpha obliquely to a horizontal H, wherein the horizontal is perpendicular to a normal, vertical between the Gurtbandaufnahmen 51, 52 adjacent load F _L , plug and housing are obliquely moved against each other.

The phases Fig. 6a-6e correspond to the phases Fig. 1a-e , they each show in plan view, sectional view AA and perspective view of a frontal sliding buckle according to the invention for straps in the most important phases of movement during opening and closing:

Fig. 6a shows a front-sliding buckle plug 1 and housing 2 with the Gurtbandaufnahmen 51 and 52, wherein the plug and housing are separated from each other. They are now put together in the direction of X. In the plug, a magnet 4 and an anchor or a second magnet 8 is provided in the housing. Due to the magnetic attraction plug 1 and housing 2 are contracted in the X direction, the magnetic force thus supports the closing under load. The magnetic force assist in closing is here because of fig1 different position of the closing direction X is not as pronounced as in Fig. 1 , The magnetic force supports the closing by the restoring force of the magnets laterally to the main attraction direction. This restoring force is weaker than the attraction in the main attraction direction. However, essential for easy closing under load is that the plug and housing are not an additional delta y as in Fig. 10a in a closure according to the prior art when closing against each other must be pulled against the load F _L , so no unnecessary force when closing is required. The attached to the plug locking pieces 5a and arranged in the housing spring ring 9 together form a snap lock.

Fig. 6b shows the frontal sliding buckle during engagement. Magnet 4 and armature or second magnet 8 are dimensioned and arranged so that their attractive force is sufficient to contract the snap lock in the direction X independently. In this case, the spring ring 9 is spread by the locking piece 5a against the spring force of the spring ring until the locking piece engages behind the locking lug 9a.

Fig. 6c shows the frontal sliding buckle after locking in the closed position. Next, the plug 1 is displaced relative to the housing 2 for opening on an inclined displacement track 60a in the opening direction Y. The oblique displacement track 60a is inclined relative to the horizontal H (perpendicular to the load F _L ) by the angle alpha, in other words: the angle between load F _L and opening direction Y is greater than 90 °.

• Magnet 4 und Anker oder zweiter Magnet 8 wurden allmählich voneinander abgeschert, wodurch eine angenehme, subjektiv kaum Kraft erfordernde Haptik erzielt wird.
• Der Zylinder 65 mit Sperrstück 5a und der Federring 9 wurden soweit seitlich gegeneinander verschoben, dass sie außer Eingriff gelangt sind, d.h. der Rastverschluss wurde geöffnet. Hierbei tritt der Zylinder durch eine Öffnung 64 im Federring.
• Erfindungsgemäß wurde der Stecker 1 auf der schrägen Verschiebebahn 60a so verschoben, dass es um einen Betrag delta x entgegen der Last F_L gezogen wurde. Hierfür war eine von der Last F_L abhängig Kraft nötig, d.h. die Frontal-Schiebeschnalle ist unter Last schwerer zu öffnen, als ohne Belastung. Je größer alpha ist, desto schwerer ist die Frontal-Schiebeschnalle zu öffnen. Es sind also verschiedene Variationen denkbar: bei einer Frontal-Schiebeschnalle für den Gebrauch an Rucksäcken etc. wird der Winkel alpha= ca. 10°-20° ausreichend für eine Sicherung der Schnalle unter Last sein. Der Winkel alpha kann für den Gebrauch an Sicherheitsausrüstung wesentlich größer gewählt werden.

Fig. 6d and Fig. 6e show the frontal sliding buckles after the shift in the open position. The displacement caused three functions:

• Magnet 4 and armature or second magnet 8 were gradually sheared off from each other, whereby a pleasant, subjectively little force-requiring feel is achieved.
• The cylinder 65 with locking piece 5a and the spring ring 9 have been moved laterally against each other so far that they have come out of engagement, ie, the snap closure has been opened. In this case, the cylinder enters through an opening 64 in the spring ring.
• According to the invention, the plug 1 has been displaced on the oblique displacement path 60a such that it has been pulled counter to the load F _L by an amount delta x. This required a force dependent on the load F _L , ie the frontal sliding buckle is harder to open under load than without load. The larger alpha is, the harder it is to open the frontal sliding buckle. So there are several variations conceivable: in a frontal sliding buckle for use on backpacks, etc., the angle alpha = about 10 ° -20 ° will be sufficient for securing the buckle under load. The alpha angle can be much larger for use on safety equipment.

Fig. 6e shows the delta x compared to the closed position and open position.

• Wird die Öffnung 64 gleich groß mit dem Zylinder 65 gewählt, wird der Federring während der Verschiebung in Richtung Y nicht gespreizt, d.h. die Frontal-Schiebeschnalle öffnet sehr leicht.
• Wird die Öffnung 64 kleiner als der Durchmesser des Zylinders 65 gewählt, wird der Federring während der Verschiebung in Richtung Y gespreizt, d.h. die Frontal-Schiebeschnalle öffnet mit einem vorbestimmten Widerstand.
• Wird die Öffnung 64 sehr klein gewählt, sodass sich der Federring weiter als beim Einrastvorrang nach Fig. 6b spreizt, liegt ein verschiedenes Öffnungsverhalten vor: Der Federring wurde dann so weit gespreizt, dass eine Öffnung auch entgegen der Schließrichtung X möglich ist, es liegt eine alternative Öffnungsvariante durch ein Beiseitedrücken des Federverriegelungselements durch eine kraftumleitende, angeschrägte Fläche nach Anspruch 2 vor.

The opening 64 in the spring ring, from which the cylinder 65 emerges at the opening, can be selected differently for different applications.

• If the opening 64 is selected to be the same size with the cylinder 65, the spring ring is not spread during the displacement in the direction Y, that is, the frontal sliding buckle opens very easily.
• If the opening 64 is selected to be smaller than the diameter of the cylinder 65, the spring ring is spread in the direction Y during the displacement, ie the frontal sliding buckle opens with a predetermined resistance.
• If the opening 64 is chosen to be very small, so that the spring ring continues after the latching priority Fig. 6b spreads, there is a different opening behavior: The spring ring was then spread so far that an opening is also possible against the closing direction X, there is an alternative opening variant by a Beiseitedrücken the spring locking element by a kraftumleitende beveled surface according to claim 2.

Fig. 7 shows in section the plug-sliding buckles Fig. 1a-e in closed position. It is further developed by the magnets 4 and 8 offset by the offset 50 so mounted against each other so that the magnetic force in the closed position generates a restoring force, which causes an automatic reset of connection module 1 in the closed position. This prevents unintentional opening under load, in particular at the beginning of an unintentional shift from the closed position to the open position in addition to the inclined sliding track.

Fig. 8a-f in plan view, sectional view AA and perspective view of an inventive arcuate plug-buckle buckle for straps in the main phases of movement during opening and closing according to claim 1,6 and 9. It is according to claim 6 in two open positions by displacement in the direction Y or Y 'to open. According to claim 9 locking piece 5a and guide rail 60a, 60a 'are formed so that the locking piece can pivot independently of the contour of locking piece and sliding track, ie that it is not necessarily performed in the contour of the sliding track. Due to the pivotability plug and housing can align collinear by the load F _L.

Fig. 8a shows the open push-sliding buckle, consisting of connector 1 and housing 2 with the Gurtbandaufnahmen 51 and 52, wherein the plug and housing are separated from each other. They are now mated in the direction X against the force F _L , which acts in the direction of the connection line between the Gurtbandaufnahmen. This connecting line is identical in this figure with the section line AA. In the plug, a magnet 4 and an anchor or a second magnet 8 is provided in the housing. Due to the magnetic attraction plug 1 and housing 2 are contracted in the X direction, the magnetic force thus supports the closing under load. On the plug attached locking pieces 5a, 5b and attached to the housing spring locking elements 9, 9 'together form a snap lock.

Fig. 8b shows the plug-in slide buckles during engagement. The locking lugs 9a, 9b of the spring locking elements are pushed aside by the locking pieces against the spring force of the spring locking elements until they engage.

Fig. 8c shows the plug-sliding buckles after locking in the closed position. Next, the plug 1 is displaced relative to the housing 2 for opening on the inclined displacement track 60 'in an opening direction Y'. In this embodiment, the displacement track according to claim 6 has two open positions, obtained by shifting in the direction of Y or Y '. The closed position is in the middle in between.

• Magnet 4 und Anker oder zweiter Magnet 8 wurden allmählich voneinander abgeschert, wodurch eine angenehme, subjektiv kaum Kraft erfordernde Haptik erzielt wird,
• Die Sperrstücke 5a, 5b und die Federverriegelungselemente 9, 9' wurden soweit seitlich verschoben, dass sie außer Eingriff gelangt sind, ohne dass das Federverriegelungselement 9, 9' beiseite gedrängt wurde, d.h. der Rastverschluss wurde ohne zusätzlichen Kraftaufwand geöffnet,
• Der Stecker 1 wurde auf der schrägen Verschiebebahn 60a' so weit verschoben, dass die Gurtbandaufnahme 51 um einen Betrag delta x entgegen der Last F_L gezogen wurde.

Fig. 8d . Fig. 8e and Fig. 8f show the arcuate plug-swivel buckle after the shift in an open position. The displacement caused three functions:

• Magnet 4 and armature or second magnet 8 were gradually sheared off from each other, whereby a pleasant, subjectively little force-requiring feel is achieved,
• The locking pieces 5a, 5b and the spring locking elements 9, 9 'have been displaced laterally to the extent that they have been disengaged, without the spring locking element 9, 9' was pushed aside, ie the snap fastener was opened without additional effort,
• The plug 1 has been moved so far on the oblique displacement track 60a 'that the Gurtbandaufnahme 51 by an amount delta x was pulled against the load F _L.

According to claim 9, the locking piece 5a within the inclined sliding track 60a or 60a 'is movable. In other words: plug and housing are indeed moved against each other, but not exactly against each other, so that plug and housing are independent of the shape of the locking piece and the sliding track against each other and can be aligned with the applied force. Fig. 8f shows a variant with a round shaped locking piece, which is particularly good in the sliding track movable, so that plug and housing can be pivoted against each other.

Fig. 8e shows the delta x compared to the closed position and open position.

Fig. 9a-e each show in plan view, sectional view AA and perspective view of an inventive arcuate plug-buckle buckle for straps in the main phases of movement during opening and closing according to claims 1 and 4. According to claim 4, the center of the circular arc Moving track 60b laterally moved to the side of the open position from the center position on the connecting line between the load holders 51, 52.

Fig. 9a shows the open, one-sided plug-swivel buckle according to claim 1 and 4, consisting of plug 1 and housing 2 with the Gurtbandaufnahmen 51 and 52, wherein the plug and housing are separated from each other. They are now mated in the direction X against the force F _L , which acts in the direction of the connection line between the Gurtbandaufnahmen. This connecting line is identical in this figure with the section line AA.

In the plug, a magnet 4 and an anchor or a second magnet 8 is provided in the housing. Due to the magnetic attraction plug 1 and housing 2 are contracted in the X direction, the magnetic force thus supports the closing under load.

On the plug attached locking pieces 5a, 5b and attached to the housing spring locking elements 9, 9 'together form a snap lock.

Fig. 9b shows the one-sided plug-swivel buckle during engagement. The locking lugs 9a, 9b of the spring locking elements are pushed aside by the locking pieces against the spring force of the spring locking elements until they engage.
