Description

Toggle closure

The invention relates to a toggle lever lock according to the preamble of claim 1.

Such a toggle closure comprises a first closure element, a second closure element, which is pivotable about a first pivot axis to the first closure element for closing the toggle closure, and a tensioning element, which is pivotally connected to the second closure element about a second pivot axis spaced from the first pivot axis.

Such toggle buckles are known from the prior art for a long time and can be used for example for tensioning a tension belt or for tightly closing a ski boot or other sports shoe. In such a toggle closure, the second closure element may be attached to the first closure element to close the toggle closure, wherein for opening the toggle closure, the second closure element is separable from the first closure element and thus the first closure element and the second closure element can be detached from each other.

In another embodiment, however, it is also possible to connect the first closure element and the second closure element articulated and non-detachable, wherein in In this case, for example, the clamping element releasably connected to a tension element, such as a belt, a belt or other designed for transmitting tensile forces element can be connected (so this is often realized, for example, in ski boots, in which a clamping element engages a tension member in the manner of a toothed belt ).

Desirable is a toggle fastener, which can be easily closed on the one hand, finding the juxtaposed parts, and the second holds reliably in the closed position. The toggle closure should be easy to use, allow a haptic pleasant opening and closing and ensure a reliable grip.

Object of the present invention is to provide a toggle closure available that is easy to use for a user, with reliable hold in the closed position.

This object is achieved by a toggle lever with the features of claim 1. Accordingly, the toggle lever closure has at least one magnetic device which acts between the first closure element and the second closure element and / or between the first closure element and the tensioning element.

The toggle closure is thus magnetically formed, wherein the magnetic device can fulfill different functions.

Firstly, the magnetic device can act, for example, between the first closure element and the second closure element such that when the second closure element is attached to the first closure element, the closure elements can be found in a simple, reliable, positionally correct manner. The magnetic device thus facilitates in this case finding the closure elements for closing the toggle lever closure.

Secondly, it is conceivable and possible for the magnetic device to act between the first closure element and the second closure element and / or between the first closure element and the tensioning element, so that the toggle closure is held reliably and resiliently in its closed position. In this case, the magnetic device thus acts in particular for fixing in the closed position. In one embodiment, the second closure element can be attached to the first closure element for closing the toggle lever closure and can be removed from the first closure element in order to open the knee lever closure. In this embodiment of a toggle lever closure, the first closure element and the second closure element are thus detachable from one another. By attaching the second closure element to the first closure element and by subsequent pivoting of the second closure element relative to the first closure element, the tensioning element pivotally connected to the second closure element is moved, thereby exerting a tensile force on a tension element adjoining the tension element, so that the toggle lever closure under tensioning of the tension element is closed. For opening, the second closure element can be pivoted back relative to the first closure element, so that the tension on the tensioning element is loosened. By removing the second closure element from the first closure element of the toggle closure is then opened.

In this embodiment, the first closure element, for example, a fastening element and the second closure element having an engagement portion, wherein the engagement portion for the articulated connection of the second closure element with the first closure element is attachable to the fastening element. The engagement portion may, for example, extend longitudinally along the first axis of rotation and be realized by a strut element that provides a hinge axis for pivoting the second closure element to the first closure element. The engaging portion engages, after attaching the second closure element to the first closure element, on the fastening element of the first closure element, wherein the engagement of the engagement portion with the fastening element is such that an articulated connection between the second closure element and the first closure element is provided.

The second closure element may have an integral pivot part on which on the one hand the engagement section is arranged and on the other hand engages the clamping element. The engagement portion and the second pivot axis about which the tensioning element is pivotable relative to the second closure element, are in this case spaced apart, so that upon pivoting of the second closure element relative to the first closure element, the tensioning element is moved and thereby a tensioning element adjoining the tensioning element is tensioned. In one embodiment, the second closure element can be configured by a wire bracket, in which the engagement portion is realized by a transverse strut of the bracket. The wire bow can be hooked into the hook-shaped fastening element in this case, so that after hooking an articulated connection between the second closure element and the first closure element.

In an alternative embodiment, the second closure element may also be formed in two parts with parts that are movable relative to one another. For example, the second closure element may have a pivoting part and a coupling element connected in an articulated manner to the pivoting part. With the pivoting part, the clamping element is hingedly connected. In contrast, the attachment element can be attached to the first closure element and carries the engagement section, so that after attaching the attachment element to the first closure part, the attachment element is held in a form-fitting manner on the first closure part and thus establishes a connection between the second closure element and the first closure element.

The attachment element may be formed, for example, as described in WO 2014/180512 A1, the content of which is to be fully included in the present case.

Alternatively, the attachment element can also be designed, for example, as described in WO 2014/090926 A1, the content of which should also be fully included in the present case.

In particular, the engagement portion may be rectilinearly extended along the first pivot axis. In this case, the engagement portion is thus directed transversely to a (directed perpendicular to the pivot axes) loading direction. Alternatively, however, the engagement portion may also be extended at an oblique angle to the first pivot axis.

Again alternatively, the engagement portion may have a V-shape, with two portions which are angled to each other and each extending obliquely to the first pivot axis and together form a V. The tip of the Vs can in this case point in a loading direction, as described in WO 2014/090926 A1. If the first closure element and the second closure element are to be attached to each other in order to close the knee lever closure, then the magnetic device can serve in particular to magnetically support the attachment of the second closure element to the first closure element. For this purpose, the magnetic device may be configured to magnetically engage the engagement portion of the second closure member during engagement with the fastener of the first closure member. When attaching the second closure element to the first closure element, the parts are thus largely self-contained, so that the application is considerably simplified for the user and a user in particular needs to approximate the second closure element only the first closure element, so that the magnetic device then engages the engagement portion can pull the fastener.

In a specific embodiment, a first magnetic element can be arranged on the first closure element in the region of the fastening element, while a second magnetic element is arranged on the second closure element in the region of the engagement section. The first and the second magnetic elements may in this case be formed as a permanent magnet. It is also conceivable and possible, however, for one of the magnetic elements to be formed by a permanent magnet and the other of the magnetic elements to be formed by a ferromagnetic armature, so that a magnetic attraction exists between the magnetic elements. When the engagement portion is brought close to the fastener, the magnetic members are tightened so that the engagement portion is pulled into engagement with the fastener and thus the second fastener is hinged to the first fastener. If the second closure element is configured with a one-piece pivoting part, the second closure element can thus be pivoted about the first pivot axis. If the second closure element is formed in two parts with an attachment element and a pivoting part (which can be pivoted about the first pivot axis to the attachment element), the pivoting part can be pivoted relative to the attachment element after attachment.

If the second closure element is embodied as a wire bow, the wire bow can itself have ferromagnetic properties, for example, so that the second closure element in the form of the wire bow is magnetically attracted to the first closure element when applied to the first closure element. Alternatively or additionally, on the second closure element in the form of the wire bracket, a cylindrical magnet or a cylindrical component with ferromagnetic Properties are arranged, which can be attached to the fastening element of the first closure element.

In an alternative embodiment of the toggle closure, as already explained, the second closure element can be connected to the first closure element in an articulated manner, but not releasably, about the first pivot axis. In this case, the second closure element is thus hingedly connected to the first closure element, wherein the hinge connection can not be solved to open the toggle lever closure. In this case, the clamping element, for example, a connecting element, for example in the form of a hook or an eyelet, which is releasably connectable with a tension member for transmitting tensile forces. By hooking the clamping element in the tension element and then pivoting the second closure element to the first closure element of the toggle closure can thus be closed, under tension on the clamping element.

In an alternative embodiment, the clamping element can also be firmly connected to the tension element. This applies to both basic embodiments of the toggle lever closure (ie with releasable connection of the second closure element with the first closure element and with non-releasable connection of the second closure element with the first closure element). The clamping element is thus not detachably connected to the tension element, wherein by pivoting the second closure element relative to the first closure element causes a tension on the tensioning element and thereby a tensile force is exerted on the tension element.

In a closed position, in one embodiment, the second closure element is arranged to the first closure element, that the connecting element of the clamping element and the second pivot axis come to rest on different sides of the first pivot axis. To close the toggle closure, the second closure element is pivoted relative to the first closure element, so that the second closure element is approximated to the first closure element and the first closure element and the second closure element, for example, come to lie approximately on each other. In this way, the clamping element is pulled along in the pivoting direction and thus tensioned, so that tensile forces are exerted on a subsequent to the clamping element tension element. For example, in the closed position, the second closure element abut with its pivoting part on a body of the first closure element, so that the second closure element occupies a defined position relative to the first closure element. The magnetic device can serve in this case in particular (also) for fixing the toggle lever closure in the closed position. For this purpose, the magnetic device at a location which is spaced from the first pivot axis, magnetically attractive act between the first closure element and the second closure element or between the first closure element and the clamping element, so that the toggle lever lock is held in the closed position. Characterized in that the magnetic device acts spaced from the first pivot axis, the magnetic fixing forces act with a lever arm to the first pivot axis, wherein the magnetic fixation between the first closure element and the second closure element or between the first closure element and the clamping element can act.

The magnetic forces can in this case be dimensioned so that when loaded during operation opening of the toggle lever lock due to the loading forces acting on the toggle lock, is not possible. Opening is only possible by deliberate actuation for pivoting back the second closure element relative to the first closure element. Additionally or alternatively, a latching device may be provided which mechanically locks the first closure element and the second closure element (and / or the first closure element and the tensioning element) in the closed position. There is thus provided an additional mechanical locking, which holds the toggle lever lock in the closed position.

In one embodiment, spring-mechanical biasing forces can act between the tensioning element and the second closure element, biasing the second closure element about the second pivot axis (about which the second closure element and the tensioning element are hinged together) relative to the tensioning element in the direction of a preferred position. Such biasing can be effected for example by a leg spring acting around the second pivot axis.

However, such a prestressing can also be effected by the second closure element having, for example, arms offset from each other along the second pivot axis, which engage the clamping element at different locations offset transversely to the second pivot axis. In a preferred position, the arms are (for the most part) relaxed. However, the second closure element becomes moved relative to the clamping element, a tension on the arms is effected, which leads to a spring bias.

In one embodiment, the second closure element has an operating element which can be actuated to open the toggle closure. The control element can be designed, for example, as a flexible, pliable release tab (for example, a piece of tape) on which it is possible to pull in order to open the toggle lever lock. The operating element can protrude, for example, in the closed position of the toggle lever closure under the tensioning element in such a way that the tensioning element can be raised by pulling on the control element and the second closure element can be released from the first closure element.

Another design of a closure device comprises a first closure element, which has a fastening element in the form of a hook, and a second closure element in the form of a wire clip for attachment to the fastening element of the first closure element. In this case, it is provided that the first closure element cooperates magnetically attractively with the second closure element. Thus, a particularly simple closure is provided, in which a second closure element in the form of a wire bracket for closing the closure is simply hooked into a hook-shaped fastening element of a first closure element. Magnetic forces act between the first closure element and the second closure element, so that the attachment of the second closure element to the first closure element is magnetically assisted.

In one embodiment, the first closure element can have a first magnetic element or at least sections can be made of a ferromagnetic material. Additionally or alternatively, the second closure element may comprise a second magnetic element or at least partially be made of a ferromagnetic material. In any case, magnetically attractive magnetic forces act between the first closure element and the second closure element. The attachment of the second closure element to the first closure element is thus magnetically assisted, and moreover the retention of the second closure element on the first closure element is magnetically secured when the closure device is closed. Such a closure device may be part of a toggle closure, as described above. In this context, reference should be made to the above. The idea underlying the invention will be explained in more detail with reference to the embodiments illustrated in the figures. Show it:

Fig. 1 shows a schematic view of an orthopedic aid 3 in the form of a rail, which can be attached to the limb of a patient, in the example shown to the leg B of the patient, and serves as a knee or Fußorthese example. For this purpose, the orthopedic aid 3 is attached to the leg B and fixed by means of toggle fasteners 1 via a plurality of tension elements 2 in the form of straps.

Hereinafter, different embodiments of such toggle fasteners 1 will be explained, it being already noted here that such toggle fasteners can be used in very different ways and are therefore not limited to use on orthopedic aids. Toggle fasteners 1, for example, generally for tensioning a belt or Belt can be used, for example, as a closure of a container or as a closure for a sports shoe, for example a ski boot.

In one exemplary embodiment of a toggle closure 1 illustrated in FIGS. 2A to 2D, a first closure element 10 has a body 100 which is fastened, for example, firmly to an object, for example an orthopedic aid 3 according to FIG. From the body 100 is a fastener 101, to which a second closure element 1 1 can be set such that an engagement portion 1 12 of the second closure element 1 1 comes to rest on a bounded by a projection 102 sliding surface 104 of the fastener 101 and thus a articulated connection between the second closure element 1 1 and the first closure element 10 creates. On the second closure element 1 1 is a clamping element 12 (in the illustrated embodiment in the form of a bracket) hinged over ends 121, wherein on a remote from the second closure element 1 1 connecting element 120 in the form of a bar strut a tension element 2, for example in the form of a Bandes or belts may be appropriate.

In the illustrated embodiment, the second closure element 1 1 and the first closure element 10 are detachable from each other. To close the toggle closure 1, the second closure element 1 1 is attached to the engagement portion 1 12 to the fastener 1 1 1, so that the engagement portion 1 12 comes to rest with a sliding surface 1 14 on the sliding surface 104 of the fastener 101. After attachment, the second closure element 1 1 is pivotable about a first pivot axis D1 relative to the first closure element 10, as shown in the transition from Fig. 2A, B to Fig. 2C, D.

When attaching the second closure element 1 1 to the first closure element 10, the fastening element 101 of the first closure element 10 comes into engagement with an opening 1 1 1 on a pivoting part 1 10 of the second closure element 1 first The attachment of the second closure element 1 1 to the first closure element 10 and the finding of the engagement portion 1 12 with the fastener 101 is magnetically assisted by magnetic elements 103, 1 13, on the one hand in the region of the fastener 101 to the body 100 of the first closure element 10 and on the other hand, in the region of the engagement portion 1 12 are arranged on the second closure element 1 1, as shown schematically in Fig. 2B. The magnetic elements 103, 1 13 are magnetically attractive, so that the engaging portion 1 12 is automatically pulled into engagement with the fastener 101 and in particular the sliding surfaces 104, 1 14 come into contact with each other.

The clamping element 12 is in contrast pivotable about a second pivot axis D2 relative to the second closure element 1 1. By pivoting the second closure element 1 1 relative to the first closure element 10, the tensioning element 12 is entrained so that a tensile force is exerted on the tension element attached to the tensioning element 12 and the tension element 2 is thus tensioned. In the closed position, shown in FIGS. 2C and 2D, the second closure element 11 is in contact with the body 100 of the first closure element 10 with the pivoting part 110. In the closed position, the second pivot axis D2 arrives at a first side of the fastening element 101 lie, while the connecting element 120 of the clamping element 12, on which the pulling element 2 engages, is arranged on a different, second side of the fastening element 101. The second pivot axis D2 and the connecting element 120 are thus arranged on different sides of the fastening element 101.

A magnetic element 103 'is arranged on the body 100 of the first closure element 10 (in addition to the magnetic element 103), which in the closed position magnetically attracts a magnetic element 1 13' (additional to the magnetic element 11) on the pivoting part 110 of the second closure element 11 is opposite. The second closure element 1 1 is thus magnetically held in the closed position, so that above the position of the second closure element 1 1 is fixed relative to the first closure element 10 in the closed position.

The magnetic attraction is preferably dimensioned such that unintentional release is not readily possible, in particular under the action of a load acting on the tensioning element 12 via the tension element 2, in any case not without conscious opening of the second closure element 11.

To open the second closure element 1 1 can be pivoted from the position shown in Fig. 2C and 2D back into the position shown in Fig. 2A and 2B, so that the magnetic elements 103 ', 1 13' are separated from each other. Then, the closure elements 10, 1 1 are removed from each other, so that the connection between the closure elements 10, 1 1 is released. In one embodiment of a toggle closure 1 shown in FIGS. 3A to 3D, the second closure element 11 is realized as a wire bow, which can be attached to a fastening element 101 in the form of a hook of a first closure element 10.

In the illustrated embodiment, a magnetic elements 103 is disposed on the fastening element 101 in the region of the sliding surface 104, which, with an attached second closure element 1 1, with a magnetic element 1 13 on a transverse strut 1 16 of the second closure element 1 1 in opposition. The magnetic element 1 13 may be formed as a permanent magnet or as a ferromagnetic component and is the magnetic element 103 on the fastener 101 magnetically attractive.

It is conceivable here to design the magnetic element 103 of the fastening element 101 as a permanent magnet. In this case, the magnetic element 1 13 may be configured as a permanent magnet or as a ferromagnetic component.

It is also conceivable to form the magnetic elements 103 as a ferromagnetic component. In this case, the magnetic element 1 13 is realized by a permanent magnet.

If the magnetic element 103 is formed as a permanent magnet, it may be possible to dispense with a separate, cylindrical magnetic element 1 13 if the wire clip implementing the second closure element 11 is made of a ferromagnetic material and thus interacts magnetically attractively with the magnetic elements 103.

Disposed from the magnetic element 1 13, the second closure element 1 1 is articulated in the form of the wire bracket with a clamping element 12, to which a tension element 2 is arranged, for example in the form of a belt or bands. The toggle closure 1 is used for tensioning the tensioning element 12 by the second closure element 1 1, as shown in the transition between Fig. 3A and 3B to Fig. 3C and 3D, about the first pivot axis D1 relative to the first closure element 10 is pivoted. In the closed position, shown in Fig. 3C and 3D, the second closure element 1 1 in the form of the wire bracket added to a latching device 105 on the body 100 of the first shutter member 10 is pivoted such that a cross member 1 15 of the second shutter member 1 1 with a latching recess 106th the latching device 105 in engagement reaches and the second closure element 1 1 is thus latchingly held in position to the first closure element 10.

The second closure element 1 1 is thus locked in the closed position with the first closure element 10. In addition, the clamping element 12 is held in position, so that the toggle lever lock 1 is fixed in its closed position.

To release the toggle closure 1, the second closure element 1 1 can be released from the latch, so that the second closure element 1 1 from the position shown in FIG. 3C and 3D can be pivoted in the direction of the position shown in FIGS. 3A and 3B, then the second Closing element 1 1 to remove from the first closure element 10 and to open the toggle lever closure 1.

A closure device of the type illustrated in FIGS. 3A to 3D can also be used without a tensioning element 12. In this case, the closure is not designed as a toggle closure, but as a simple closure in which a second closure element 1 1 is hooked to close the closure device in a simple manner in the fastener 101 of the first closure element 10 and the stop of the closure elements 10, 1 1 to each other is magnetically secured.

A locking device is not required in this case. The closing of the closure takes place by simply hooking the second closure element 1 1 in the first closure element 10. In an embodiment of a toggle closure 1 shown in Fig. 4A to 4D, the second closure element 1 1 is formed in two parts. The second closure element 1 1 has a Ansetzelement 1 17, which may be formed as described in WO 2014/180512 A1, the content of which is to be fully included in the present case.

With the Ansetzelement 1 17 - pivotable about the first pivot axis D1 - a pivot member 1 10 articulated, which is extended with arms 1 18, 1 19 of the Ansetzelement 1 17 and these arms 1 18, 1 19 with a connecting portion 123 of a Clamping element 12 is connected.

To close the toggle closure 1, the attachment element 1 17 is attached to the first closure element 10, so that the attachment element 1 17 with an engagement portion 1 12 in the fastener 101 and arranged thereon Projection 1 12 engages, as shown in Fig. 4B. In this case, the attachment element 1 17 comes to lie on the body 100 of the first closure element 10 between the attachment element 101 and a blocking element 107 in the form of a projection, so that the position of the attachment element 1 17 is fixed to the first closure element 10.

Both the Ansetzelement 1 17 and the body 100 of the first closure member 10 each have a magnetic element, so that the attachment of the Ansetzelements 1 17 takes place on the body 100 in a magnetically assisted manner. The Ansetzelement 1 17 is attracted by the body 100, so that the attachment element 1 17 passes in a magnetically assisted manner in the position shown in Fig. 4B.

If the attachment element 1 17 has been attached to the first closure element 10, then the pivot member 1 10 can be pivoted about the first pivot axis D1 with respect to the Ansetzelement 1 17, so as to tension the clamping element 12 with the tension element 2 arranged thereon, as this in the transition from FIG. 4B to FIG. 4D.

The pivoting part 1 10 is thereby pivoted in a pivoting direction S1 about the first pivot axis D1 relative to the Ansetzelement 1 17 and thus with respect to the first closure element 10, wherein the clamping element 12 is pivoted in a pivoting direction S2 about the second pivot axis D2 relative to the pivot member 1 10 as can be seen in the transition from Fig. 4B to Fig. 4D. The tension element 2 on the clamping element 12 is taken and thus stretched to train.

On the clamping element 12, a handle 122 is attached to which a user can attack to close the toggle closure 1 or reopen. Thus, a user can pull on the handle 142 to open and thus lift the tensioning element 12 so that the pivoting part 110 is pivoted back about the first pivot axis D1 and also the tensioning element 12 about the pivot axis D2.

In the embodiment according to FIGS. 4A to 4D, the arms 1 18, 1 19 of the pivoting part 1 10, via which the attachment element 1 17 is connected to the tensioning element 12, do not extend parallel to one another, but extend at an angle to one another, as shown in FIG. 5A to 5C. Thus, as can be seen in the enlarged view of FIG. 5B, arms 1 18, 1 19 engage with their ends 1 18A, 1 18B at a distance A transverse to (in this case, virtual) second pivot axis D 2 on the shaft Connecting portion 123 of the clamping element 12, which causes the pivot member 1 10 is biased in a preferred position.

In this preferred position, shown in Fig. 5A and 5B, the arms 1 18, 1 19 are largely relaxed. Upon pivoting of the pivoting part 1 10 relative to the clamping element 12 about the second pivot axis D2, the arms 1 18, 1 19 deformed, resulting in clamping forces on the arms 1 18, 1 19, trying to reset the pivot member 1 10 in the direction of the preferred position , The ends 1 18A, 1 19A can in this case, for example, in mutually offset openings on both sides of the connecting portion 123 engage the clamping element 12, so that the arms 1 18, 1 19 held at their ends 1 18 A, 1 19 A at a distance A to each other at the connecting portion 123 , The pivoting part 1 10 can also be biased in a different manner relative to the clamping element 12, for example via a leg spring, which acts around the second pivot axis D2 and biases the pivoting part 1 10 in the direction of a preferred position relative to the clamping element 12. In an embodiment of a toggle closure 1 shown in FIGS. 6A to 6C and 7A, 7B, an engagement element 11 (which is configured similarly to the embodiment according to FIGS. 4A to 4D) is attached to a first closure element 10 for closing the toggle closure 1 By means of a blocking element 107 in the form of a projection on the body 100 of the first closure element 10, the position of the attachment element 1 17 is also defined rearwardly of the attachment element 101 by the attachment element 1 17 between the fastening element 101 and the blocking element 107 is received. The first closure element 10 has a magnetic element 103, as can be seen from FIGS. 7A and 7B, and likewise the attachment element 1 17 has a magnetic element (not visible in the figures), so that the attachment element 1 17 magnetically engages during attachment the fastener 101 is pulled. Both the first closure element 10 and the attachment element 1 17 can in this case have a magnetic element in the form of a permanent magnet. It is also conceivable and possible, however, that one of the elements has a permanent magnet and the other of the elements has a ferromagnetic armature. The closing of the toggle closure 1 is carried out in a completely analogous manner as described above for the exemplary embodiment according to FIGS. 4A to 4D. By pivoting the pivot member 1 10 about the first pivot axis D1 relative to the Ansetzelement 1 17 and thus relative to the first closure member 10 and by simultaneous pivoting of the clamping member 12 about the second pivot axis D2 relative to the pivot member 1 10 of the toggle closure 1 comes into the closed position according to FIG. 6C, in which the tensioning element 12 lies substantially on the first closure element 10 and thus a tension element 2 acting on the tensioning element 12 (see FIG. 6A) is tensioned.

At a connecting portion 123, to which the pivoting part 1 10 of the second closure element 1 1 hinged about the second pivot axis D2, a latching device 124 is formed in the form of two hooks in the closed position of the toggle closure 1 with a latching device 105 in the form of two locking recesses 106th of the first closure element 10 are engaged, so that the clamping element 12 is locked relative to the first closure element 10. The toggle closure 1 is thus secured in the closed position and can not be readily opened, at least not unintentionally under the action of load forces on the tension element 2.

In the illustrated embodiment, an operating element 13 in the form of a release lug is arranged on the attachment element 1 17, on which a user can pull to open the toggle lever closure 1. By lifting the clamping element 12 on a handle 122 and pulling on the operating element 13, the toggle lever 1 can be opened and the attachment element 1 17 are released from the first closure element 10.

It is also conceivable and possible to provide in a modified embodiment, no handle 122 on the clamping element 12, but the control element 13 in the closed position under the clamping element 12 protrude. By pulling on the operating element 13, the tensioning element 12 can then be raised in a movement sequence and the attachment element 17 can be released from the first closure element 10.

In the embodiments described above, the engagement portion 1 12 extends in a straight line along the first pivot axis D1. However, this is not limiting. Also conceivable are other embodiments of the engaging portion 1 12th For example, the engaging portion 1 12 may form a V-shape, as shown schematically in FIG. 8. In this case, the engagement portion 1 12 can engage with a likewise V-shaped fastening element 101 on the first closure element 10 into engagement and thus produce a positive connection when attached to the first closure element 10 second closure element 1.

The attachment element may be formed in this case, as described for example in WO 2014/090926 A1.

In the embodiments described above, the second closure element 1 1 (releasably) to be attached to the first closure element 10 to close the toggle lever closure 1. When opening the toggle closure 1, the second closure element 1 1 can be removed from the first closure element 10 in order to release in this way the connection between the second closure element 1 1 and the first closure element 10.

In another embodiment, shown schematically in Fig. 9, however, is also conceivable, the second closure element 1 1 to the first pivot axis D1 hinged, but not releasably connected to the first closure element 10. The clamping element 12 can in this case, for example articulated and also not releasably attack about the second pivot axis D2 pivotally mounted on the second closure element 1 1, wherein the clamping element 12 can be releasably connected to the tension element 2, for example by the tensioning element 12 in a hook 20 of the tension element. 2 is hooked. Again, a toggle closure 1 is provided, in which by pivoting the second closure element 1 1 clamping forces can be exerted on the tension element 2.

In a modified embodiment is also conceivable, in the embodiment of FIG. 9, the connection of the clamping element 12 with the tension element 2 not releasably to design. In this case can be effected by closing the toggle closure 1, a tension that can be relaxed by opening the toggle fastener 1, but without parts in this case are to be detached from each other. The idea underlying the invention is not limited to the embodiments described above, but can in principle also be implemented in a completely different manner. A toggle closure of the type described here can be used in very different ways for the exciting joining parts together. One application may be to attach an orthopedic device, such as an orthosis, to a patient, in which case the orthopedic device is strapped to one limb of the patient via one or more toggle fasteners. However, a toggle closure of the type described here can also be used, for example, for closing a container, for example a box or a bag, or for closing a sports shoe, for example a ski boot.
