EP3515224B1 - Closure device for connecting two parts - Google Patents

Description

The invention relates to a locking device for connecting two parts according to the preamble of claim 1.

Such a closure device, for example, from U.S. 3,102,314 is known, comprises a first closure part having a first surface with an arrangement of first structural elements arranged thereon, and a second closure part having a second surface with an arrangement of second structural elements arranged thereon. The first closure part and the second closure part are to be attached to one another in such a way that the first surface of the first closure part faces the second surface of the second closure part, so that the first structural elements and the second structural elements engage in one another in such a way that movement of the closure parts relative to one another along a loading direction Is blocked.

Such a closure device can be used, for example, on textile objects, for example items of clothing, for example a bra. However, the closure device can also be used to connect other parts, for example as a closure for a bag, backpack, suitcase or other container or for example also for a protective vest, for example a life jacket or the like.

At one from the U.S. 7,478,460 known closure device, closure parts have a surface structure with arc-shaped elements. By placing the closure parts together, the circular elements engage with each other so that the closure parts are held together.

At one from the U.S. 5,983,467 known closure device closure parts on structural elements in the form of, for example, mushroom-shaped projections that can hook together in order to bring about a hold between the closure parts in this way.

In the case of a closure device that can be used, for example, as a closure for a textile garment (in the manner of a hook-and-loop fastener), it is desirable that loads, particularly under tension, can be absorbed in a favorable, reliable manner. The closure device should be easy to close and also easy to open, but should be able to withstand high forces under load. A variable usability with inexpensive production is also desirable.

From the U.S. 3,102,314 a closure device is known in which arrangements of structural elements in the form of, for example, cuboid magnetic elements are arranged on closure parts.

At one from the U.S. 4,197,618 known magnetic closure device has a closure part on magnetic poles to which another, ferromagnetic closure part can be attached.

the DE 20 2009 006 189 U1 describes a magnetic connecting mechanism consisting of two parts for the adjustable connection of two belts or other parts, the slipping or sliding of the parts in the longitudinal direction being prevented or limited by a wavy formation of the surface of the magnetic, magnetizable or magnet-containing parts.

It is the object of the present invention to provide a closure device which is suitable for absorbing tensile loads while being easy to close and also easy to open again.

This object is solved by an object with the features of claim 1.

Accordingly, the first closure part has a first magnet arrangement with a plurality of magnetic poles offset from one another along the first surface and the second closure part has a second magnet arrangement with a plurality of magnetic poles offset from one another along the second surface.

The closure device can be closed by attaching its closure parts to one another. Each closure part has an arrangement of structural elements on its surface, which engage with one another when the closure parts are attached, so that the closure parts are fixed to one another so that they can withstand tensile loads. The direction of loading is in the plane of the surfaces of the closure parts. The loading is thus along a direction tangential to the surfaces.

The surfaces of the closure parts each extend over an area. The closure parts are preferably flexible at least in sections and can therefore be flexibly adapted in shape, for example curved.

In this case, the engagement between the arrangements of the structural elements on the surfaces of the closure parts takes place due to magnetic interaction between the closure parts. For this purpose, a magnet arrangement with a plurality of magnetic poles is arranged on each closure part, the magnet arrangements facing each other magnetically when closing and when closure parts are attached to one another (with complete or at least partial opposite magnetic poles). Due to the magnetic interaction, the closing of the closure device is thus easy, and in addition, when the closure parts are attached to one another, the structural elements of the closure parts are held in engagement magnetically, so that the hold of the closure parts on one another is magnetically secured.

The magnetic poles of each magnet assembly are offset from one another along the surface of the associated closure member. The magnet arrangement is therefore multi-pole and has several different magnetic poles (north poles and south poles) towards the magnet arrangement of the other closure part, with opposite magnetic poles of the magnet arrangements of the closure parts being attracted to each other when the closure parts are attached to one another and the closure device is closed.

The multi-pole magnet arrangement can in particular also have the effect that the closure parts can be attached to one another in a limited number of discrete positions. These discrete positions are dictated by such positions in which the magnet arrangements of the closure parts face each other in a magnetically attractive manner, unlike magnetic poles of the magnet arrangements are thus located directly opposite one another.

For example, to open the closure parts, they can simply be pulled apart from one another, as a result of which the structural elements of the closure parts disengage from one another. It may be conceivable and possible to move the closure parts relative to one another in the opposite direction to the loading direction for opening, which, with the appropriate polarity of the magnet arrangement, can cause, for example, this tangential opening movement to bring poles of the magnet arrangement with the same name closer together and thus the closure parts to move magnetically repel each other. This can contribute to a particularly easy opening of the closure device that is pleasant to the touch.

In one embodiment, the closure parts are hermaphroditic and each have the same arrangement of structural elements. The first structural elements of the first closure part thus correspond in their shape (and optionally also in their arrangement) to the second structural elements of the second closure part. In particular, the first structural elements can protrude from the surface of the first closure part and the second structural elements can protrude from the surface of the second closure part and thus be designed as protruding engagement projections.

In the closed position of the closure device, the first structural elements of the first closure part and the second structural elements of the second closure part engage in one another. In principle, the structural elements can be formed very differently by any shaped projection elements or by any structural shaping on the surface. For example, the arrangement of structural elements can also be formed by roughening with irregularly shaped, possibly microscopically small mountains and valleys on the surface of the associated closure part. The arrangement of first structural elements on the first surface of the first closure part and the arrangement of second structural elements on the second surface of the second closure part creates a structural shape on the respective surface that is designed to engage with the structural shape of the respective other surface and in the closed position of the locking device creates a connection that can withstand tensile loads.

In one configuration, the first structure elements have first blocking surfaces and the second structure elements have second blocking surfaces. When the closure parts are attached to each other the structural elements with their blocking surfaces facing each other, so that when the closure parts are loaded in the loading direction, the blocking surfaces come into contact with one another and in this way movement of the closure parts relative to one another in the loading direction is blocked.

The blocking surfaces can extend, for example, as surfaces directed perpendicularly to the surface.

Alternatively, the blocking surfaces can also form undercuts and for this purpose extend at an (acute) angle to the surface.

Other undercut geometries on the structural elements are also conceivable and possible. Thus, the structural elements can have latching lugs or webs or the like, which can be brought into engagement with one another.

A movement of the closure parts relative to one another in the loading direction is blocked via the blocking surfaces. The closure parts cannot be moved tangentially to one another in the loading direction, so that tensile forces on the closure parts can be absorbed and a loadable connection is thus created in the loading direction when the closure parts are attached to one another.

It is conceivable and possible here that the connection can be subjected to tensile loads not only in the direction of loading, but also against the direction of loading. For this purpose, the first structural elements can each have a further blocking surface on a side facing away from the first blocking surface, and the second structural elements can also each have a further blocking surface on a side facing away from the second blocking surface. When loaded against the loading direction, the structural elements come into contact with one another via their further blocking surfaces, so that the connection between the closure parts is also secured against the loading direction.

In another embodiment, however, it can also be provided that the closure parts can be moved towards one another counter to the direction of loading, for example in order to adapt the closed position of the closure parts to one another and to tension the closure device, for example. For this purpose, the first structural elements can have first abutment surfaces and the second structural elements can have second abutment surfaces, the first structural elements and the second structural elements abutting one another with their abutment surfaces when the closure parts are loaded counter to the loading direction. The first Structural elements thus point with their blocking surfaces in the direction of loading, while their ramp surfaces point in the opposite direction to the loading direction. The run-on surfaces can, for example, extend obliquely to the surface of the associated closure part and form ramps, which run up on one another counter to the direction of loading when the closure parts move relative to one another.

A kind of mechanical freewheel against the direction of the load can be created by means of such ramp surfaces. While the closure parts lock to one another in the event of a tensile load in the direction of the load, the structural elements of the closure parts can slide over one another when the load is applied in the opposite direction to the loading surfaces, so that the position of the closure parts in relation to one another can be adjusted in the opposite direction to the load.

The first structural elements and/or the second structural elements each have a curved shape or a V-shape when the respective surface is viewed from above. The structural elements can be arc-shaped or V-shaped.

The tip of the V-shape can point in the direction of loading, for example. The structural elements of a closure part can be separated from one another transversely to the direction of loading, it also being conceivable and possible to connect several structural elements to one another transversely to the direction of loading, for example to form a zigzag line or a curved line. By interrupting the structural elements from one another, favorable flexibility can be obtained on the respective closure part, for example.

In one configuration, the structural elements can, for example, each have at least one leg which extends along the assigned surface and is aligned at an oblique angle to the direction of loading. If the structural elements are V-shaped, each structural element can have two legs, for example, which are aligned at an angle, in particular an obtuse angle, to one another. Due to the V-shaped design, the engagement between the structural elements is preferably self-reinforcing, in that the first structural elements on the first surface of the first closure part are pulled into engagement with the second structural elements on the second surface of the second closure part when loaded in the direction of loading and through the engagement the V-shape, the structural elements in particular cannot be displaced to one another transversely to the direction of loading.

The first structural elements can be arranged, for example, in a grid pattern on the first surface of the first closure part, while the second structural elements are arranged in a grid pattern on the second surface of the second closure part. Thus, the first structural elements can be arranged on the first surface in rows offset from one another along the loading direction, while the second structural elements are arranged analogously in rows on the second surface. In this case, the structural elements of adjacent rows, viewed transversely to the direction of loading, cannot be offset from one another. Or the structural elements of adjacent rows can be offset from one another (exactly) by half the width of a structural element, measured transversely to the direction of loading.

The first magnet arrangement of the first closure part and the second magnet arrangement of the second closure part are each formed with a plurality of magnetic poles which are offset from one another along the surface of the respective associated closure part. Each magnet arrangement can be formed by an arrangement of (discrete) permanent magnet elements that are inserted, for example, in a recess provided for this purpose in the closure part and thus point with different poles toward the surface of the associated closure part. However, it is also conceivable and possible to design each closure part with a multi-pole permanent magnet film, it being possible to glue or weld such a permanent magnet film to a body forming the surface on the back of the structural elements, or to design the body itself with such a permanent magnet film, on the surface of which the structural elements are directly formed.

The permanent magnet elements can be designed as neodymium magnets, for example. A permanent magnetic film is, for example, a plastic-bonded, flexible, permanent-magnetic film that can contain, for example, a magnetic powder with a neodymium content, for example.

The magnetic poles of the first magnet arrangement and/or the magnetic poles of the second magnet arrangement are preferably lined up periodically. The magnetic poles thus form an arrangement with, for example, magnetic poles that are offset from one another along the loading direction and/or transversely to the loading direction and lined up next to one another.

In one configuration, the magnetic poles of the first magnet arrangement and/or the magnetic poles of the second magnet arrangement can be lined up next to one another along the loading direction. Along the load direction, the north and south poles are lined up alternately, resulting in a (periodic) sequence. In this way, discrete positions for connecting the closure parts to one another can be specified, in which the magnetic poles of the first closure part and the magnetic poles of the second closure part are opposite each other so that the closure parts are magnetically attracted to one another and the structural elements of the closure parts engage with one another.

The first structural elements and/or the second structural elements preferably have a first periodicity and the magnetic poles of the first magnet arrangement and/or the magnetic poles of the second magnet arrangement have a second periodicity, each viewed along the loading direction. In this case, the first periodicity can correspond to the second periodicity or to an integer multiple of the second periodicity. If, for example, the structural elements of the first closure part and the structural elements of the second closure part are arranged with the same (first) periodicity and this first periodicity corresponds to the second periodicity with which the magnetic poles of the first magnet arrangement and the second magnet arrangement are arranged in relation to one another, then via the magnetic poles a discrete number of positions can be defined in which the closure parts can be fitted together and just engage their structural elements. The magnetic attraction between the closure parts thus causes attachment in such a way that the structural elements reliably engage with one another and the closure device thus reliably closes.

If the first periodicity corresponds to the second periodicity or to an integer multiple of the second periodicity, this can also provide a simple opening or possibly a type of magnetic freewheeling. Provision can thus be made for the closure parts to be displaced relative to one another in the opposite direction to one another when the closure parts are loaded in the opposite direction to the loading direction, as a result of which the magnet arrangements of the closure parts with poles of the same name are brought closer to one another and thus repel one another, so that the closure device can be opened particularly easily . Likewise, in this way structural elements can be jumped over by magnetic repulsion when the closure parts are moved towards one another against the direction of loading, so that when the closure parts are moved towards one another the structural elements do not engage with one another in the load direction. With such a magnetic freewheel, a ramp-shaped design of the structural elements is not required by providing appropriate run-on surfaces.

The first closure part and the second closure part are preferably displaceable relative to one another by a release distance counter to the loading direction in order to provide magnetic freewheeling. When shifted by the release path, the magnet arrangements of the closure parts with poles of the same name come into opposition and thereby repel each other (the magnet arrangements reverse polarity relative to one another). The structural elements on the surfaces are arranged relative to one another in such a way that when they are displaced by the release path, each structural element of one closure part does not collide with the structural element on the other closure part that follows in the opposite direction to the load.

The release path preferably corresponds to half the periodicity of the magnet arrangements along the direction of loading.

The magnet arrangements of the closure parts are preferably lined up and positioned along the loading direction in such a way that when the closure parts are placed against one another, the structural elements can reliably engage with one another, but their blocking surfaces do not yet abut against one another. After attachment, the closure parts thus have a certain amount of play with respect to one another in the direction of loading and are not (yet) secured to one another, in particular transversely to the direction of loading, so that the closure parts can be displaced relative to one another transversely to the direction of loading. This can allow easy opening by transverse displacement of the closure parts relative to one another. Under load, the structural elements then come into contact with the blocking surfaces in contact with one another, with this contact also blocking a transverse displacement of the closure parts relative to one another, particularly in the case of a V-shaped configuration of the structural elements.

In addition or as an alternative to the arrangement along the loading direction, the magnetic poles of the first magnet arrangement and the magnetic poles of the second magnet arrangement can also be arranged in a row along a transverse direction extending transversely to the loading direction. In this way, discrete positions for connecting the closure parts can be specified, which are offset from one another transversely to the loading direction. This arrangement of magnetic poles is also advantageous, for example, in Connection with the "mechanical freewheel" described above, because this arrangement of the magnetic poles causes a positioning effect transversely to the direction of loading during adjustment against the direction of loading.

In one embodiment, magnetic poles are lined up both in the loading direction and transversely to the loading direction, resulting in a two-dimensional grid of alternating magnetic poles (north poles and south poles).

Not part of the invention is a closure device for connecting two parts, which comprises a first closure part having a first surface with an arrangement of first structural elements arranged thereon and a second closure part having a second surface with an arrangement of second structural elements arranged thereon. The first closure part and the second closure part are to be attached to one another in such a way that the first surface of the first closure part faces the second surface of the second closure part, so that the first structural elements and the second structural elements engage in one another in such a way that movement of the closure parts relative to one another along a loading direction is blocked is. It is provided that the first closure part has a first magnet arrangement and the second closure part has a second magnet arrangement, the first magnet arrangement and/or the second magnet arrangement being formed at least in sections by a permanent magnet foil.

The advantages and advantageous configurations described above can also be applied analogously to this closure device. In particular, the features of all subclaims can also be combined with this closure device.

A closure device of the type described above can be used in particular for a textile closure, ie a closure for connecting textile parts, in particular for items of clothing. Jackets, belts, shoes or other items of clothing, for example a bra, can be closed by means of such a textile fastener.

1 12 shows an exemplary embodiment of a closure device 1, which has a first closure part 2 extending over a surface area and a second closure part 3 extending over a surface area. The closure device 1 can be used, for example, as a closure on a piece of clothing (for example on a jacket), on a container (for example on a bag or on a backpack) or on a vest (for example a protective vest, a life jacket or the like).

Each closure part 2 , 3 has a body 20 , 30 with a peripheral edge 200 , 300 and a raised section 201 , 301 projecting over the edge 200 , 300 . A surface 203, 303 is formed on the raised section 201, 301, on which structural elements 22, 32 of identical shape are arranged.

The closure parts 2, 3 can be attached to one another with their surfaces 203, 303 and thereby engage with one another with their structural elements 22, 32. In a recess 202, 302 formed on the rear of the raised section 201, 301, a magnet arrangement 21, 31 is accommodated on each closure part 2, 3, which causes the closure parts 2, 3 to be magnetically attracted to one another when they are attached to one another and in an attached to one another Position are held together magnetically.

2 shows a plan view of the arrangement according to FIG 1 . Figures 3A to 3C show the closure device 1 in a closed position and Figures 4A to 4C when moving against the load direction B1, B2.

The structural elements 22, 32 on the surfaces 203, 303 of the closure parts 2, 3 each have a V-shape, with legs 222, 322 which are aligned at an obtuse angle to one another, as is shown schematically in FIG 3D is shown. In cross section, shown in Figure 3C and Figure 4C , the structural elements 22, 32 each have a sawtooth shape, with blocking surfaces 220, 320 extending at an acute angle to the surface 203, 303 on a first side of the legs 222, 232, which form an undercut with the surface 203, 303, and ramp surfaces 221, 321 on the other side of legs 222, 232 which extend at an obtuse angle to surface 203, 303 and each form a ramp.

In the closed position of the closure device 1, in which the closure parts 2, 3 are attached to one another, the structural elements 22, 32 of the closure parts 2, 3 face each other in such a way that the blocking surfaces 220, 320 of the structural elements 22, 32 face each other, such as this out Figures 3A to 3C is evident. If the closure parts 2, 3 are loaded relative to one another along a loading direction B1, B2 (by pulling on the first closure part 2 in the loading direction B1 and on the second closure part 3 in the loading direction B2), the structural elements 22, 32 pass over their blocking surfaces 220, 320 in contact with one another, so that a relative movement between the closure parts 2, 3 along the loading direction B1, B2 is blocked. The closure device 1 can thus be subjected to tensile loads and is also able to absorb large forces without the closure parts 2, 3 being able to become detached from one another due to the effect of the force.

The engagement between the structural elements 22, 32 is brought about and maintained here on the one hand due to the undercuts of the blocking surfaces 220, 320 and is also secured by the magnetic attraction between the magnet arrangements 21, 31.

How out Figures 3A and 3D As can be seen, the structural elements 22, 32 are separated from one another transversely to the loading direction B1, B2 on each closure part 2, 3, in that gaps are formed between the structural elements 22, 32. The structural elements 22, 32, which have a V-shape when viewed from above, point with the vertex of the V in the respective associated loading direction B1, B2 (the structural elements 22 point with the vertex of the V in the loading direction B1, while the structural elements 32 of the V point in the loading direction B2).

To open the closure device 1, the closure parts 2, 3 are removed from one another. This can be done by lifting one closure part 2, 3 from the other closure part 3, 2. However, the opening can also take place by pulling on the closure parts 2, 3 counter to the loading direction B1, B2, namely in a release direction L1, L2, as is shown in Figures 4A to 4C is shown.

By moving the closure parts 2, 3 in the release direction L1, L2 relative to one another, the structural elements 22, 32 run onto one another with their abutment surfaces 221, 321, and due to the ramp shape of the abutment surfaces 221, 321, the closure parts 2, 3 are at least slightly apart lifted. This weakens the magnetic force of attraction between the magnet arrangements 21, 31 of the closure parts 2, 3, so that the closure parts 2, 3 can be easily removed from one another.

The ramp shape of the structural elements 22, 32 behind the blocking surfaces 220, 320 also enables a type of mechanical freewheeling when the closure parts 2, 3 are pulled against the loading direction B1, B2 (in the release direction L1, L2). When the first closure part 2 is pulled in the release direction L1, a structural element 22 of the first closure part 2 is removed with its blocking surface 220 from an associated blocking surface 320 of a structural element 32 of the second closure part 3 and slides with its ramp surface 221 onto a ramp surface 321 of one in the Adjoining structural element 32 of the second closure part 3 adjoining the release direction L1. After the structure element 22 of the first closure part 2 has passed this adjacent structure element 32 of the second closure part 3, the blocking surface 22 of this structure element 22 is now located opposite the blocking surface 320 of the adjacent structure element 32 that has just passed, so that the closure parts 2, 3 exactly a structural element 22, 32 are offset from one another along the loading direction B1, B2.

By moving the closure parts 2, 3 relative to one another in the release direction L1, L2, the position of the closure parts 2, 3 can thus be adjusted to one another by moving the closure parts 2, 3 tangentially. The result is a ratcheting sliding of the closure parts 2, 3 relative to one another.

In the embodiment according to Figures 1 to 4A-4C w the magnet arrangements 21, 31 have magnetic poles N, S, which are offset from one another transversely to the loading direction B1, B2, as is shown in FIG 2 is shown. The magnet assemblies 21, 31 are thus transverse to Load direction B1, B2 periodically. The periodicity of the magnetic poles N, S of the magnet arrangements 21, 31 is such that when the closure parts 2, 3 are placed on one another, the structural elements 22, 32 of the closure parts 2, 3 engage with one another in the correct position so that they can be locked via their blocking surfaces 220, 320 to lock when loaded. Due to the multi-pole nature of the magnet arrangements 21, 31, it is thus easier to attach the closure parts 2, 3 to one another in the correct position, with reliable closure of the closure device 1.

Other pole arrangements of the magnet arrangements 21, 31 are conceivable and possible, as is shown in different exemplary embodiments in Figures 5 to 7 is shown.

6 in this case corresponds functionally to the arrangement of the exemplary embodiment according to FIG Figures 1 to 4A-4C .

In the embodiment according to figure 5 the magnetic poles N, S of each magnet arrangement 21, 31 are offset from one another along the loading direction B1, B2, in that the magnetic poles N, S are lined up alternately in a periodic manner along the loading direction B1, B2.

In the embodiment according to 7 in contrast, each magnet arrangement 21, 31 has a two-dimensional pattern of magnetic poles N, S, with a multiplicity of rows of magnetic poles along the loading direction B1, B2 and two columns in the transverse direction Y transverse to the loading direction B1, B2.

With the magnetic poles N, S offset from one another along the loading direction B1, B2 in the exemplary embodiments according to 5 and 7 can in particular be brought about that the closure parts 2, 3 along the loading direction B1, B2 engage with one another in the correct position. In particular, the magnet arrangements 21, 31 can be arranged relative to one another in such a way that the structural elements 22 of the first closure part 2 and the structural elements 32 of the second connection part 3 come to lie between one another and not on top of one another when the closure parts 2, 3 are attached (which would otherwise result in incomplete closure of the locking device 1 could result).

In the two-dimensional distribution of the magnetic poles N, S of each magnet arrangement 21, 31 according to the embodiment 7 can a positioning in the correct position can be facilitated both along the loading direction B1, B2 and transversely to the loading direction B1, B2.

The magnet arrangements 21, 31 can be formed by discrete permanent magnet elements, for example by neodymium magnets. Each magnet arrangement 21, 31 can be accommodated in the recess 202, 302 in the body 20, 30 of the associated closure part 2, 3 and bonded or cast to the body 20, 30 of the closure part 2, 3. In this case, the depression 202, 302 can be closed off from the outside, e.g. by a cover, for example a foil or the like.

Alternatively, each magnet arrangement 21, 31 can also be formed by a magnetic foil, for example a plastic foil, which contains, for example, a magnetic powder with a neodymium content. Such a magnetic foil can be accommodated in the recess 202, 302 of the associated closure part 2, 3 and glued to the body 20, 30 or connected in some other way. However, it is also conceivable to produce the body 20, 30 of the closure parts 2, 3 entirely from such a magnetic foil, so that in this case the body 20, 30 and possibly also the structural elements 22, 32 arranged thereon are magnetic.

Figures 8 to 12A-12D show another embodiment of a closure device 1, which differs from the basis of Figures 1 to 4A-4C described embodiment in particular by the shape of the structural elements 22, 32 differs.

In the embodiment according to Figures 8 to 12A-12D have the structural elements 22, 32, which are analogous to the exemplary embodiment according to FIG Figures 1 to 4A-4C V-shaped, on the back of blocking surfaces 220, 320 there are no ramp-shaped ramp surfaces, but are directed perpendicularly to the surfaces 203, 303 on rear surfaces 223, 323 (facing away from the blocking surfaces 220, 320).

In the closed position, shown in Figures 10A to 10D , the structural elements 22, 32 each engage in intermediate spaces between the structural elements 32, 22 on the respective other part, each structural element 22 of the one, first closure part 2 with its locking surfaces 220 formed on the legs 222, 322 locking surfaces 320 on the legs 322 of an associated structural element 32 of the other, second closure part 3 is opposite, like this Figures 10C and 10D is evident.

How out Figures 10C and 10D can also be seen, in the position shown, the magnet arrangements 21, 31 of the closure parts 2, 3 face each other with opposite magnetic poles N, S, so that the closure parts 2, 3 attract each other and the structural elements 2, 3 3 together in the in Figures 10A to 10D shown plant.

When the closure parts 2, 3 are loaded in the loading direction B1, B2 relative to one another, the blocking surfaces 220, 320 of the structural elements 22, 32 come into contact with one another, with undercuts being formed on these blocking surfaces 220, 320 so that the engagement between the structural elements 22, 32 cannot be easily released under load and is therefore able to absorb large loading forces.

The structural elements 22, 32 are dimensioned and arranged relative to one another in such a way that the closure parts 2, 3 can be displaced relative to one another in the release direction L1, L2 by a release distance LW corresponding to half the periodicity of the magnetic poles N, S of the magnet arrangements 21, 31, without the structural elements 22 , 32 abut one another in the release direction L1, L2.

If the closure parts 2, 3 are to be released from one another, the closure parts 2, 3 can be moved relative to one another by the release path LW counter to the loading direction B1, B2, i.e. in a release direction L1, L2, so that the structural elements 22, 32 with their blocking surfaces 220, 320 disengage from each other and also the magnet arrangements 21, 31 are moved towards one another in such a way that like poles N, S of the magnet arrangements 21, 31 are brought closer to one another, as is shown in particular in Figures 11C and 11D is evident. The closure parts 2, 3 thus repel each other, so that the closure parts 2, 3 can be easily detached from each other.

By pulling on the closure parts 2, 3 in the release direction L1, L2, the position of the closure parts 2, 3 can also be adjusted counter to the load direction B1, B2, i.e. in the release direction L1, L2 - in the manner of a magnetic freewheel. Thus, the structural elements 22 of the one, first closure part 2 jump over the following structural element 32 of the other, second one when pulled (and the resulting displacement by the release path LW) in the release direction L1 on the closure part 2 due to the magnetic repulsion between the closure parts 2, 3 Closure part 3 as shown in Figures 11C and 11D is shown. With another train in the In the release direction L1, L2, the closure parts 2, 3 are pulled towards one another again when the magnet arrangements 21, 31 again come to face each other with opposite poles, as is shown in Figures 12C and 12D is shown. Each structural element 22 of the first closure part 2 thus comes in turn with its blocking surfaces 220 opposite blocking surfaces 320 of structural elements 32 on the other, second closure part 3, so that the closure parts 2, 3 in the release direction L1, L2 by just the periodicity of the magnetic poles N, S of the magnet arrangement 21, 31 (corresponding to the spacing (the periodicity) of adjacent rows of structural elements 21, 31) are offset from one another.

Due to the fact that when the closure parts 2, 3 are attached to one another, the structural elements 22, 32 initially come to lie at a distance from one another (viewed along the loading direction B1, B2) (see FIG Figures 10A to 10D ), a transverse displacement of the closure parts 2, 3 along the transverse direction Y is possible in the unloaded state. This is not prevented because the locking surfaces 220, 320 of the structural elements 22, 32 do not abut and engage with one another. Such a transverse displacement can enable the closure device 1 to be opened simply by pushing the closure parts 2, 3 off from one another.

Different arrangements and shapes of structural elements 22, 32 on the closure parts 2, 3 are conceivable and possible.

At the in 13 illustrated embodiment, each closure part 2, 3 structural elements 22, 32 which are aligned in a grid pattern to each other. Each closure part 2, 3 is provided with several rows A, B, each with a plurality of structural elements 22, 32, which structurally interact when the closure parts 2, 3 are attached in such a way that a relative movement of the closure parts 2, 3 in the loading direction B1, B2 are locked to each other.

In the embodiment according to 13 the structural elements 22, 32 of the different rows A, B, viewed transversely to the loading direction B1, B2, are not offset from one another. The structural elements 22, 32 of the different rows A, B of each closure part 2, 3 are thus aligned with one another (when viewed along the loading direction B1, B2).

In contrast, the structural elements 22, 32 of adjacent rows A, B in the exemplary embodiment according to FIG 14 just about half the width of a structure element 22, 32 (measured transversely to the loading direction B1, B2) offset from one another. Again, the structural elements 22, 32 of the two closure parts 2, 3 act together in a locking manner when the closure parts 2, 3 are attached to one another.

In the embodiment according to 15 the structural elements 22, 32 are each formed by a straight projection element extending obliquely to the loading direction B1, B2. The structural elements 22, 32 of adjacent rows A, B are in this case arranged as mirror images of one another (the center line between the rows A, B corresponding to the mirror axis). Together, the structural elements 22, 32 thus block a relative movement of the closure parts 2, 3 in the loading direction B1, B2 and also transversely to the loading direction B1, B2.

At the in 16 In the exemplary embodiment illustrated, the structural elements 22, 32 are V-shaped in their basic form, but are curved at their tips. In the closed position, the structural elements 22 of the first closure part 2 come to lie between the structural elements 32 of the other, second closure part 3 (viewed in the transverse direction Y transverse to the loading direction B1, B2).

In the embodiment according to 17 the structural elements 22, 32 are formed in the shape of a circular arc.

If the magnetic poles N, S of the magnet arrangements 21, 31 are lined up alternately along the loading direction B1, B2, then the magnet arrangements 21, 31 can be aligned with one another just as is shown in an exemplary embodiment in FIG Figures 18A to 18C is shown. There, when the magnetic poles N, S are located opposite one another for attaching the closure parts 2, 3, the blocking surfaces 220, 320 of the structural elements 22, 32 of the two closure parts 2, 3 are spaced apart from one another. When the closure parts 2, 3 are attached to one another, the blocking surfaces 220, 320 do not come into direct contact with one another, but rather the structural elements 22, 32 come (initially) to lie between one another. This can make it easier to attach the closure parts 2, 3 to one another because tilting of the structural elements 22, 32, in particular structural elements 22, 32 lying one on top of the other, is avoided. The blocking surfaces 220, 320 only come into contact with one another when there is a load in the load direction B1, B2, as in Figure 18C shown, so that a relative movement between the closure parts 2, 3 is blocked.

This is shown analogously in Figures 19A to 19C for an embodiment in which the structural elements 22, 32 have undercuts on their blocking surfaces 220, 320. In this case in particular, the positioning of the closure parts 2, 3 can be facilitated by the opposite positioning of the magnetic poles N, S of the magnet arrangement 21, 31 with the blocking surfaces 220, 320 of the structural elements 22, 32 being at a distance from one another.

Figures 20 to 26 show different exemplary embodiments of magnet arrangements 21, 31 with magnetic poles N, S of different periodicity P2 (along the loading direction B1, B2) and with different shapes of the magnetic poles N, S.

In the exemplary embodiment according to FIG 20 the periodicity P2 of the magnet arrangement 21, 31 corresponds precisely to the periodicity P1 of the structural elements 22, 32.

In the embodiment according to 21 In contrast, the periodicity P2 of the magnet arrangement 21, 31 corresponds to four times the periodicity P1 of the structural elements 22, 32. In the exemplary embodiment according to FIG 21 the number of positions in which the closure parts 2, 3 can be attached to one another in a magnetically attractive manner is thus significantly reduced.

Figures 22 to 24 show magnet arrangements 21 with different periodicity P2 along the loading direction B1, B2. In the embodiment according to 23 is the periodicity P2 compared to the periodicity P2 of the embodiment according to 22 halved, and in accordance with the embodiment 24 the periodicity P2 of the magnetic poles N, S of the magnet arrangement 21 is halved compared to the periodicity P2 of the magnet arrangement 21 in the exemplary embodiment according to FIG 23 .

25 and 26 illustrate that the magnetic poles N, S do not necessarily have to extend in a straight line along the transverse direction (or optionally also along the loading direction B1, B2), but can also have a V-shape, for example. It is also possible here, as in 26 shown to design the magnetic poles N, S in a zigzag shape, with a periodicity P3 along the transverse direction Y.

The closure device 1 with its closure parts 2, 3 can be flexible at least to a certain degree in order to be used, for example, on a piece of clothing or on a container. However, care must be taken here that torsion on the structural elements 22, 32 does not result in the structural elements 22, 32 are disengaged from each other when the closure parts 2, 3 are attached to one another and the connection between the closure parts 2, 3 is thus released.

For this purpose, the extension of the structural elements 22, 32 obliquely to the loading direction B1, B2 can be advantageous, as shown below with reference to FIG Figures 29 to 34 should be explained.

In the case of a structural element 22 extending in a straight line and oriented transversely to the loading direction B1, B2, as is the case in FIG 27 and 29 is shown, as well as in an arrangement of a plurality of linearly extending, transversely aligned structural elements 22, as exemplified in Figures 31A and 31B shown, the length X1 along which the structural element 22 acts to stiffen against a torsion T about the transverse direction Y (in the direction of a curvature along the loading direction B1, B2) corresponds precisely to the edge width over which the structural element 22 is attached to the body 20 of the associated Closure part 2 is attached.

A single structure element 22 (see for example 27 and 29 ) and also an arrangement of structural elements 22 (see Figures 31A and 31B ) can hardly counteract a torsion T, which acts around the transverse direction Y and leads to a curvature along the loading direction B1, B2.

This is different in the case of obliquely extending structural elements 22, as exemplified in FIG 28 and 30 for a row A of structural elements 22 and in 32A, 32B for a plurality of rows A, B of structural elements 22 lined up next to one another. For a structural element 22 extending obliquely, the length X2 over which the structural element 22 has a stiffening effect against a torsion T about the transverse direction Y corresponds to the length projected onto the loading direction B1, B2, as illustrated 30 and Figures 32A and 32B is evident. The structural elements 22 thus effectively counteract a torsion T about the transverse direction Y and a curvature of the closure part 2 along the loading direction B1, B2.

In addition, the obliquely extending structural elements 22 also have the effect of self-reinforcing the connection between the closure parts 2, 3 33 and 34 is evident.

Thus, in the case of a structural element 22 extending in a straight line, which is as in Figure 33 shown is aligned transversely to the direction of loading B1, B2, a transverse displacement along the transverse direction Y is not prevented, so that the closure parts 2, 3 even in the loaded State can be moved transversely to each other and thus an opening of the closure device 1 in the loaded state, possibly also an unintentional opening, is possible.

In the case of obliquely extended structural elements 22, as in 34 shown, a force F is transferred to the structural elements 22 in a normal force FN and in a tangential force FQ, with the tangential force FQ acting in the direction of the adjacent structural element 22 along the transverse direction Y and is thus supported by this adjacent structural element 22. This is how it works with the in 34 Structural element 22 shown below exerts the tangential force FQ obliquely upwards and is supported by the structural element 22 arranged above the structural element 22, so that the engagement of the arrangement of structural elements 22 of the closure part 2 in the associated structural elements 32 of the other closure part 3 is self-reinforcing and in particular along a transverse displacement the transverse direction Y is inhibited.

Completely different structural forms of the structural elements on the surfaces of the closure parts are also conceivable and possible. For example, a roughening with (microscopically) small structural elements can be provided on the surfaces, which can protrude regularly or irregularly from the surface and thus form peaks and valleys arranged regularly or irregularly with respect to one another.

The closure parts can have a magnet arrangement of discrete permanent magnet elements, for example neodymium magnets.

However, it is also conceivable and possible for the closure parts to have one or more magnetic foils which are glued or welded to the bodies of the closure parts. In this context, it is also conceivable and possible for the bodies of the closure parts themselves to be formed from a permanent magnetic (foil) material, for example by incorporating a magnetic powder.
