Definitions
- Connection device for connecting a first connection section to a second connection section
- the present invention relates to a connecting device for detachably connecting a first connecting portion to a second connecting portion. Furthermore, the invention relates to a flat structure comprising at least one such connecting device.
- Connection devices that are used to detachably connect a first connection section to a second connection section should provide the connection between the two connection sections in the simplest and quickest possible way and also make it possible to release the connection again as quickly and easily as possible.
- the two connecting sections can be connected to objects that are to be detachably connected to one another.
- the connecting devices are often designed like a zipper. With a slider, opposing staples are brought into one another in a form-fitting manner when closing and separated again when opening.
- the zipper allows the two connection sections to be connected to one another without interruption.
- the zipper can be opened and closed much more quickly and easily compared to a connection with buttons.
- the object of one embodiment of the present invention is to propose a connecting device for connecting a first connecting section to a second connecting section, with which it is possible with simple and inexpensive means to transmit increased forces acting perpendicular to the locking line. Furthermore, one embodiment of the present invention is based on the object to provide a fabric with such a connecting device.
- One embodiment of the invention relates to a connecting device for connecting a first connecting section to a second connecting section, comprising
- a second connecting section to which a plurality of second magnetic bodies or second magnetisable bodies is attached, whereby for connecting the first connecting section to the second connecting section, o one of the first magnetic bodies is used between two adjacently arranged second magnetic bodies or vice versa or o one the first magnetic body can be positioned between two adjacent second magnetizable bodies,
- the first magnetic bodies each have a recess and the second magnetic bodies or the second magnetizable bodies each have a projection or vice versa and
- the magnetic bodies preferably consist of permanent magnets, also called permanent magnets, while the magnetizable bodies initially have no magnetic effect and due to the spatial proximity to the magnetic bodies of the same ben magnetized and therefore attracted.
- the magnetizable bodies can also be magnetized during manufacture.
- the magnetizable bodies are made of a ferromagnetic material, preferably iron.
- magnets After magnetization, permanent magnets retain this for a long time.
- Metallic alloys of iron, nickel and aluminum with additives of cobalt, manganese and copper or ceramic materials are typically used for production.
- Particularly strong magnets are made from rare earths in a sintering process, such as samarium-cobalt or neodymium-iron-boron.
- the magnetizable bodies can also be used in powder form, which is incorporated into a sealing compound that is liquid during manufacture and then aligned and magnetized with an external magnetic field.
- the connecting device can be used in particular where a sealed closure is required, for example in diving suits. Silicone, for example, can be used as a sealant.
- the polarity alignment of the first magnetic body and the second magnetic body runs along the closure line.
- the second magnetizable bodies these are magnetized with a corresponding pole orientation.
- Polarity alignment is to be understood as meaning the arrangement of the poles in the connected state. Due to the fact that the first magnet bodies and the second magnet bodies not only adhere to one another due to the magnetic force acting between them, but also that a positive connection is also effected, the connecting device according to the present disclosure only opens when opening forces act perpendicularly to the closure line, which are significantly higher than those forces at which generic zippers open according to the prior art. This effectively prevents the connecting device from being opened unintentionally.
- first magnetizable bodies can also be used instead of the first magnetic bodies, provided the connecting device has the second magnetic bodies.
- first magnetic body and the second magnetic body can be constructed identically.
- second magnetic bodies Due to the fact that the first magnet body and the second magnet body are constructed identically, they can be manufactured in very large quantities, which means that the costs for providing the proposed connecting device can be kept low.
- the first magnet body and the second magnet body can be formed in a spherical shape, with the recess being designed in the shape of a segment of a sphere.
- the second magnetic body Due to the fact that the recess according to the present embodiment is designed in the shape of a segment of a sphere, a separate projection no longer needs to be provided. Rather, the spherical magnetic body itself acts as a projection which can engage in the recess in the shape of a segment of a sphere.
- the recess in the shape of a segment of a sphere in a manner corresponding to the rest of the magnetic body, so that a possible large-scale contact of the magnetic body in the ku gel segment-shaped recess of the adjacent magnetic body can be achieved.
- the magnetic bodies can move relative to each other without losing the form fit. The movement relative to one another causes a certain flexibility to be provided within the connecting device, with which tolerance deviations are compensated.
- this movement is a "nodding movement”.
- This flexibility can also be increased with the material of the first connection section and the second connection section, for example by the material used having increased extensibility or elasticity.
- At least one first positioning magnet body can be arranged on the first connecting section and/or at least one second positioning magnet body can be arranged on the second connecting section.
- the proposed connection device can also be closed if the first connection section is offset relative to the closure line in relation to the second connection section and is therefore arranged in a manner deviating from the intended positioning.
- a similar effect can occur with jackets that are closed with buttons when a button is not placed in the associated buttonhole, but in example in the adjacent buttonhole. This has a negative effect on the fit of the jacket.
- the use of a positioning magnetic body ensures that the two connecting sections are aligned in their desired position relative to one another. Ferromagnets or permanent magnets can be used as positioning magnets.
- first positioning magnet body and the second positioning magnet body can be arranged in such a way that they interact with one another when they are connected.
- first positioning magnetic body and the second positioning magnetic body can be spaced significantly from the remaining first magnetic bodies and the remaining second magnetic bodies.
- connection device can comprise a first pair of positioning magnetic bodies with a first polarity alignment and a second pair of positioning magnetic bodies with a second polarity alignment, the first pair of positioning magnetic bodies and the second pair of positioning magnetic bodies being arranged adjacent to one another and the first polarity alignment and the second polarity alignment perpendicular to the closure line and run opposite to each other.
- the first pair of positioning magnet bodies and the second pair of positioning magnet bodies each include a first positioning magnet body and a second positioning magnet body.
- the poling orientation can be defined, for example, by means of a line connecting the north pole with the south pole.
- One or both Magne thnesmagnet emotions can be designed as a permanent magnet.
- One of the positioning magnet bodies of a pair of positioning magnet bodies can be configured as a magnetizable body or as a ferromagnet.
- the first positioning magnetic body has a shape deviating from the shape of the first magnetic body and/or
- the second positioning magnetic body have a shape deviating from the shape of the second magnetic body.
- the connecting device cannot be closed or not properly closed at least at the point where a positioning magnetic body is to be positioned between two adjacent magnetic bodies arranged on the opposite connecting section.
- the user receives clear feedback that the first connection section and the second connection section are not aligned with one another as intended.
- a further developed embodiment can be characterized in that the first positioning magnetic body has a magnetic force that differs from the magnetic force of the first magnetic body and/or the second positioning magnetic body has a magnetic force that differs from the magnetic force of the second magnetic body. It is advisable that the magnetic force of the first positioning magnetic body and the second positioning magnetic body is greater than that of the first magnetic body and the second magnetic body. Be the first Connecting section and the second connecting section moves towards each other, the two positioning magnet bodies will first attract each other, whereby the intended alignment of the first connecting section can be provided relative to the second connecting section.
- At least one of the first magnetic bodies can have a stronger magnetic force than the other first magnetic bodies and/or at least one of the second magnetic bodies can have a stronger magnetic force than the other second magnetic bodies.
- the magnet bodies can be equipped there with an increased magnetic force in order to counteract the opening.
- At least one of the first magnetic bodies can have a different shape than the other first magnetic bodies and at least one of the second magnetic bodies can have a different shape than the other second magnetic bodies.
- the actual shape of the magnet body can remain the same in the geometric sense, but the size can change. It can be useful for the size to change continuously along the closure line. The magnetic field acting along the closure line in the connected state is only disturbed to a small extent as a result.
- dem User specified a clear alignment with which the first connection section and the second connection section should be connected to each other.
- the first magnetic bodies each have a channel-shaped first recess and
- the second magnet body each have a channel-shaped second recess, wherein
- the trough-shaped first depression in the connected state is arranged in alignment with the trough-shaped second depression, and
- the connecting device has a magnetic locking rod which, in the connected state, can be introduced into the channel-shaped first depressions and into the channel-shaped second depressions.
- the magnetic locking bar is inserted into the first recess and the second recess in the connected state. In doing so, it is attracted by the first magnetic bodies and the second magnetic bodies and consequently held on them, so that it cannot become detached from them in an uncontrolled manner.
- the first magnetic body and the second magnetic body are designed spherically, you can align largely freely relative to each other despite the magnetic force acting between them. Since in many cases flexible fabrics, in particular textile fabrics, are to be connected to one another, an uneven closing pattern can occur along the magnet body.
- the locking bar reduces the degree of freedom with which the magnet bodies can orient themselves relative to one another. info meanwhile, the magnetic bodies line up along the locking bar, so that a linear locking pattern is provided. In addition, the minimum necessary opening forces acting in the plane of the fabric are increased.
- the first magnetic bodies each have a first through hole and
- the second magnet body each have a second passage bore, wherein
- the first through-hole in the connected state is arranged in alignment with the second through-hole
- the connecting device has a closure body which, in the connected state, can be passed through the first through bores and the second recesses.
- At least one of the first magnet bodies and/or at least one of the second magnet bodies has a waist for fixing a fastening strap.
- a fastening strap can be looped around the waist, which is secured by the waist against slipping.
- the fastening band serves to bind the magnetic bodies to the connecting portions. That Fastening tape can be riveted, for example cut with the kausab.
- the connec tion device can have a sliding body which partially encompasses the first magnetic body and the second magnetic body and can be moved along the first magnetic body and the second magnetic body and fixed within the connecting device.
- the sliding body can be operated in a similar way to a slider of a zipper and also fulfills a similar function to the slider.
- the sliding body supports the positioning of the first and second magnetic bodies when the connecting device is closed, this support being unnecessary due to the magnetic force acting attractively between the first and second magnetic bodies.
- the sliding body can also transmit tensile forces between the first and second magnetic bodies.
- the sliding body can be positioned where increased tensile forces act perpendicularly to the closure line and there is a risk of the connecting device opening.
- the sliding body can also be used for the following purpose: In the event that the connecting device is only to be partially closed, the sliding body is moved to the point up to which the connecting device is to be closed.
- the sliding body keeps the first magnetic body and the second magnetic body at a distance, so that no or no sufficiently large magnetic force acts between the first and the second magnetic forces.
- the sliding body itself can also consist of a magnetic or magnetizable material, in particular iron, consist of or include this, so that a magnetic force acts between the sliding body and the magnetic bodies. This magnetic force can be dimensioned in such a way that the sliding body remains in a certain position and does not move in an uncontrolled manner.
- a rod can be connected to the sliding body. The use of a rod is particularly useful if the connecting device is to be used to connect two connecting sections that extend over areas that are difficult to access, for example at heights that are otherwise only accessible with a ladder.
- first connection section and the second connection section can be arranged on a common fastening tape.
- the connecting device can be used in the manner of a hook and loop fastener.
- the first connecting portion and the second connecting portion are separated, for example by an eyelet through which the common fastener tape is passed.
- the connecting device is particularly suitable for opening and closing shoes, in particular sandals.
- One embodiment of the invention relates to a fabric comprising at least one connecting device according to one of the previous embodiments.
- the technical effects and advantages that arise with the proposed fabric suffice correspond to those discussed for the present connection device.
- the connecting device only opens with forces acting perpendicularly to the closure line, which are significantly higher than the forces at which generic zip fasteners according to the prior art open. This effectively prevents the connec- tion device from being opened inadvertently.
- the fabrics are in particular configured as textile fabrics.
- the sheet-like structure has at least two connecting devices according to one of the previous embodiments, the second connecting section being completely or partially delimited by the connecting devices.
- the fabric has two connecting devices, these can be arranged in a V-shape.
- the second connecting section has approximately the shape of a triangle in plan view, being firmly connected to the first connecting section at the edge which connects the two free ends of the two connecting devices to one another.
- the second connection section is connected to the first connection section in the manner of a hinge and can be opened accordingly without the connection between the first connection section and the second connection section being broken. In this way, for example, a jacket pocket can be closed and opened if necessary.
- the fabric can be designed as a sail of a sailing boat, the two connec tion devices are opened from a certain force, which is applied by the wind on the sail.
- This force can be chosen to prevent the sailboat from capsizing can be prevented.
- the same effect is produced as when the sail is opened, but independently of the intervention of the sailor in question. If the force that the wind exerts on the sail decreases, the two connecting devices close again.
- the number of connecting devices used and their arrangement in relation to one another are not limited.
- An implementation of the present invention relates to a connecting device for detachably connecting a first connecting section to a second connecting section, comprising
- first magnet units each having o a primary first magnetic body and a pri mary second magnetic body or o a first primary magnetic body and a pri mary second magnetizable body

- a magnet unit is formed from two structural units, namely from a first magnet body and a second magnet body or from a first magnet body and a second magnetizable body.
- first magnetic body and the second magnetic body can be spatially separated from each other.
- Connection units and the like can be arranged in between.
- This implementation is therefore particularly suitable for long-stretched connecting devices, for example for tents or for attaching tarpaulins to trucks or trains or for attaching mosquito nets to door frames.
- the primary first magnetic body and the secondary ERS th magnetic body each have a recess and the primary second magnetic body and the secondary second magnetic body each have a projection or vice versa, wherein the projections engage in the Ausneh rules in the connected state.
- second magnetizable bodies are used instead of the second magnetic bodies.
- a further implementation specifies that the first magnet unit is equipped with a first through-channel and the second magnet unit is equipped with a second through-channel through which a securing element, in particular a flexible securing element, can be guided.
- a securing element in particular a flexible securing element
- a rod can be used as a rigid securing element, while a rope or wire can be used as a flexible securing element.
- the opening force required to open the connec tion device can be further increased.
- rigid securing elements can be implemented as rods. These can consist of or comprise a magnetizable material or can be designed as a ferromagnet. Where the first magnetic bodies interact with the second magnetic bodies in the connected state, the magnetic force acting between them can be increased due to the magnetizing ability of the rigid securing elements.
- the connecting device When using flexible securing elements, the connecting device can be easily adapted to non-linear or changing courses of the closure line. If the connecting device is fitted with a flexible If the securing element is not required, it can be folded up to save space. It also prevents some of the magnetic units from getting lost.
- connection device comprises a tensioning device with which the flexible securing element can be pretensioned. In the tensioned state, it is prevented that the first magnet units and the second magnet units can unintentionally become detached from one another. As a result, the opening force required to open the connecting device is increased.
- the form fit between the first magnet units and the second magnet units can be maintained even with larger opening forces.
- a clamping screw which is connected to the same at a first end of the fle xible securing element
- the flexible securing element can be tensioned and released again in a simple manner and in a short time.
- the fastening element can be designed, for example, in the manner of part of a bayonet catch which the flexible securing element can be attached to a stationary arranged complementary second part of a Bajo nice closure.
- the flexible securing element it is also possible, please include the flexible securing element to be attached to the first magnet unit or to the second magnet unit in the area of the second end of the flexible securing element. To this end, it may be sufficient to arrange a stop on the flexible fuse element, which strikes against the magnet unit in question.
- One implementation is characterized in that a number of stiffening bodies are arranged on the flexible securing element.
- the stiffening bodies are arranged in such a way that they can be displaced along the first through channel and the second through channel as a result of pulling the flexible securing element and can be arranged in such a way that they can be inserted into both a first magnetic body and a second magnetic body connected to the first Magnetic body cooperates, inra conditions. In this position, the stiffening body is surrounded by the first magnetic body and the second magnetic body.
- the reinforcing bodies make it more difficult for the interacting magnetic bodies to be released, so that the opening force required to open the connecting device can be increased.
- the stiffening bodies consist of or comprise a magnetizable material. Due to the fact that the stiffening bodies are made of a magnetizable material or include this, the magnetic force between the interacting first magnetic bodies and second magnetic bodies is increased.
- the use of a spacer makes it possible to keep the magnetic bodies at the desired distance from one another, which is particularly advantageous when the connec tion device is used to connect textile fabrics.
- the first spacer is designed as a first spring and/or the second spacer is designed as a second spring.
- a minimum distance between the magnetic bodies is specified and, on the other hand, it is ensured that the connecting device can be adapted to different courses of the closure line.

- the connecting device 101 includes a first connecting portion 12 to which a plurality of first magnetic bodies 14 is fixed.
- the connecting section 12 can consist of a textile material which can be designed in the manner of a web of fabric or in the manner of a belt.
- the first dacasab section 12 is connected to a first fabric 16, which is designed as a first textile fabric 16 and can be part of a jacket, not shown, a room divider, a roll-up, a sail or the like, for example.
- the fibers of the first fabric 16 can be natural or synthetic fibers.
- the first dacasab section 12 can be sewn onto the first fabric 16 or glued to it.
- a fastening strap 18 is provided in each case in the illustrated exemplary embodiment.
- the fastening strip 18 can also be sewn to the first flat structure 16 and to the first connecting section 12, with rivet connections, screw connections, adhesive connections or the like also being conceivable.
- the connection of the fastening strap 18 to the first magnetic body 14 can be implemented in such a way that the first magnetic body 14 has a through-opening, not shown here, through which the fastening strap 18 can be passed. The fastening strap 18 is then guided in the manner of a loop.
- a plurality of second magnetic bodies 20 are connected to a second connecting portion 22, the second connecting portion 22 being fixed to a second sheet 24.
- the first surface structure 16 and the second surface structure 24 can form the first connecting section 12 or the second connecting section 22 .
- the first magnetic bodies 14 are directly connected to the first sheet 16 using the fastening straps 18 already mentioned
- the second magnetic bodies 20 are directly connected to the second sheet 24 using the fastening straps 18 already mentioned.
- the first magnet body 14 and the second magnet body 20 have a polarity which is marked in FIG. 1 with N for the north pole and S for the south pole.
- the first magnetic body 14 and the second magnetic body 20 are arranged such that in the connected state a first magnetic body 14 is arranged between two adjacent second magnetic bodies 20 and a second magnetic body 20 is arranged accordingly between two adjacent first magnetic bodies 14 .
- the first magnetic bodies 14 and the second magnetic bodies are in the connected state 20 arranged along a closure line L.
- a polarity orientation PM can be defined, which defines the arrangement of the poles of the magnetic bodies 14, 20 in the connected state.
- the polarity alignment PM can be understood, for example, as a line which connects the north pole of a first magnet body 14 to the south pole of an adjacent second magnet body 20 . It can be seen that in the connected state the polarity orientation PM runs at least approximately parallel to the closure line and coincides with it.
- the first magnetic body 14 and the second magnetic body 20 are aligned in such a way that, in the connected state, the north pole of the first magnetic body 14 points to the south pole of the adjacent second magnetic body 20 and vice versa.
- the first magnetic body 14 exerts a first magnetic force EMI and the second magnetic body 20 exerts a second magnetic force EM2. Both the first magnetic force EMI and the second magnetic force EM2 act mainly parallel to the closure line L.
- the first magnetic bodies 14 and the second magnetic bodies 20 attract each other, adhere to each other in the connected state and consequently connect the first connecting section 12 and the second connecting section 22 commonality.
- the magnet bodies 14 , 20 have a recess 26 and a projection 28 .
- the magnet bodies 14, 20 have a spherical section 30 or are designed in the form of a ball as a whole, with the recess 26 being designed in such a way that the spherical section 30, for example of a first magnet body 14, fits into the recess 26 an adjacent arranged second magnetic body 20 can engage.
- the recess 26 can be designed in the shape of a segment of a sphere.
- the spherical section 30 acts as such as a projection 28, and it is just as conceivable to provide a projection 28 that differs significantly from the rest of the shape of the magnetic bodies 14, 20.
- the projection 28 engages in the recess 26, so that a positive connection perpendicular to the closure line L is produced.
- the magnetic force acting between two adjacent magnet bodies 14, 20 ensures that this positive locking is maintained in the connected state. Forces which act perpendicularly to the closure line L are at least partially distributed to the magnetic bodies 14, 20 via the form fit.
- the opening force FO In order to open the connecting device 10i, the opening force FO must therefore be large enough to cancel the form fit against the acting magnetic force. In comparison to the zip fasteners known from the prior art mentioned at the outset, the opening force FO is significantly greater. An uncontrolled opening of the connecting device 10i is therefore avoided.
- FIG. 2 a second embodiment of the proposed connecting device IO2 is also shown in a top view in the connected state.
- the essential structure of the connecting device IO2 according to the second embodiment largely corresponds to the structure of the connecting device 10i according to the first embodiment shown in FIG. only the main differences will be discussed below.
- the connecting device IO2 according to the second embodiment includes, in addition to the first magnetic bodies 14 and the second magnetic bodies 20, two first positioning magnetic bodies 32 and two second positioning magnetic bodies 34.
- a polarity alignment PP can also be defined with regard to the poles of the positioning magnetic bodies 32, 34. This runs at least approximately perpendicularly to the closure line L and in the plane of the first connecting section 12 and the second connecting section 22.
- the first positioning magnet body 32 and the second positioning magnet body 34 are arranged at a distance from the adjacent first or second magnet bodies 14, 20, in order to different course of the magnetic fields not to influence negatively.
- the first and second positioning magnetic bodies 32, 34 have a different external shape than the first and second magnetic bodies 20.
- the positioning magnetic bodies have no projection 28 and no correspondingly designed recess 26.
- the magnetic force which acts between a first positioning magnet body 32 and a second positioning magnet body 34 arranged opposite, can be selected such that it is greater than the first magnetic force FM1 and the second magnetic force FM2.
- the connecting device IO2 When a user wants to close the Vietnamesesvor direction IO2, two oppositely arranged positioning magnetic body will attract more than the first magnetic body 14 and the second magnetic body 20. As a result, the first connecting portion 12 and the second connecting portion 22 positioned relative to each other. Then the user needs the first connection section 12 and the second connection section 22 only to let go. The connecting device IO2 then closes by itself as a result of the acting magnetic forces.
- the provision of the first positioning magnetic bodies 32 and the second positioning magnetic bodies 34 prevents the first connecting portion 12 and the second connecting portion 22 from being offset in the connected state along the locking line L deviating from the intended orientation. It is consequently prevented that, for example, a jacket is closed "crookedly".
- FIG. 3 shows a third embodiment of the proposed connecting device 10 3 , the main difference from the first embodiment shown in FIG. 1 being that some of the first magnetic bodies 14 and some of the second magnetic bodies 20 have a greater first magnetic force FM1 or exert a greater second magnetic force FM2 than other first magnetic bodies 14 and other second magnetic bodies 20.
- Those magnetic bodies 14, 20 which exert an increased magnetic force are shown hatched in FIG. 3 for identification purposes.
- a desired positioning of the first connecting section 12 and the second connecting section 22 can be brought about when those first magnet bodies 14 and those second magnet bodies 20 which exert an increased magnetic force are attached to the respective ends the connec tion device 10 are arranged. As can be seen from FIG.
- first magnetic bodies 14 lying on the inside and second magnetic bodies 20 lying on the inside are also designed in such a way that they exert an increased first magnetic force FM1 or second magnetic force FM2.
- the inner first magnetic body 14 and the Internal second magnetic bodies 20, which exert an increased first or second magnetic force FM2 serve less to position the first connecting section 12 in relation to the second connecting section 22 and more to generate the opening forces FO that are necessary to open the connecting device 10 3 , to increase.
- the opening forces FO are not distributed uniformly along the closing line L on the first magnetic body 14 and the second magnetic body 20, the first magnetic body 14 and the second magnetic body 20, which each exert an increased magnetic force, can be positioned there where the opening forces FO are particularly large.
- first magnetic bodies 14 and all of the second magnetic bodies 20 it is therefore not necessary to design all of the first magnetic bodies 14 and all of the second magnetic bodies 20 in such a way that they exert an increased magnetic force.
- the production costs can be kept low, since cheaper magnets, for example made of magnetized iron instead of neodymium, can be used for those first magnet body 14 and second magnet body 20 which exert a lower first or second magnetic force FM2.

- the locking rod 42 or the locking cord 43 is held in the first depressions 36 and the second depressions 38 by the first magnet bodies 14 and the second magnet bodies 20 due to the magnetic force acting between them and is therefore not lost in an uncontrolled manner.
- the locking rod 42 or the locking strand 43 ensure that opening forces FO, which act perpendicular to the locking line L and within the plane of representation in Figure 4, do not result in the first magnetic bodies 14 and the second magnetic bodies 20 being removed from one another and consequently being separated the connection device IO4 can open.
- the connecting device IO4 can only be opened in the manner described above if the closing rod 42 or the closing strand 43 is removed, provided a sufficiently large opening force FO is applied.

- the first magnetic bodies 14 and the second magnetic bodies 20 are moved toward one another, which can be seen from the middle region of the figure 5 emerges.
- the magnetic forces acting between the first magnetic bodies 14 and the second magnetic bodies 20 are now so great that they are transferred into the connected state as soon as the sliding body 44 has been pushed over them.
- the sliding body 44 also has another function:
- the sliding body 44 can also be made of a magnetic or magnetized material, so that it is held by the first magnetic bodies 14 and the second magnetic bodies 20 in a specific position, which can be specified by the user. As a result, with the positioning of the sliding body 44, the user can determine how far the connection device IO 5 should be closed.

- the first spacer 84 is designed as a first spring 104 and the second spacer 86 as a second spring 106 .
- a flat structure 16 is attached to a carrier 108 by means of a connecting device 10 according to the eleventh, twelfth or thirteenth exemplary embodiment.
- the first magnet units 76 are fastened to the carrier 108 and the second magnet units 78 are fastened to the textile fabric 16 .
- the sheet-like structure 16 it is arranged in such a way that one of the second magnet units 78 is positioned between two adjacently arranged first magnet units 76.
- the fuse element 92 are then guided through the first through-channels 91 and the second through-channels 93 .
- the securing element 92 can also be designed as a stiff locking bar 42 (cf. FIG.
- the flexible securing element 92 can be guided through the first through-channels 91 and the second through-channels 93 with the aid of gravity, with the weight of the stiffening body 96 being helpful here. In the case of the flexible fuse element 92, this can then be braced. In this way, for example, a tarpaulin can be attached to a truck or a flag to a pole.
- the magnetic force of some of the first magnetic bodies 80 and second magnetic bodies 82 lying against one another can be greater than the magnetic force of the remaining magnetic bodies.
- the concept of the positioning magnet bodies 32, 34 already described can also be implemented here, so that the correct positioning of the sheet-like structure 16 relative to the carrier 108 can be simplified.
