Fastening device comprising two fastening parts

Abstract

The proposed solution relates in particular to a fastening device (V) for connecting two parts (RS1, RS2; Z1, Z2) and comprising a first fastening part (1) and a second fastening part (2), wherein the first fastening part (1) comprises a first load-application portion (101), which is intended for connecting to a first part (RS1, Z1) of the two parts (RS1, RS2; Z1, Z2) to be connected to one another, and wherein the second fastening part (2) comprises a second load-application portion (201), which is intended for connecting to a second part (RS2, Z2) of the two parts (RS1, RS2; Z1, Z2) to be connected to one another. According to a first aspect of the proposed solution, the first and second fastening parts (1, 2) can be placed on one another along a placement axis (S) and connected to one another, wherein, in an interconnected state, the fastening parts (1, 2) can be pivoted relative to one another about the placement axis (S). Applying a loading (F1a, F1b) to the first and second load-application portions (101, 201) in a direction away from the placement axis (S) allows the fastening parts (1, 2) to be pivoted about the placement axis (S) from the placement position into an engagement position, in which at least one form-fitting element (11, 11.1, 11.2, 11.3; 21, 21.1, 21.2, 21.3) of the one fastening part (1, 2) engages on an engagement region (22, 22.1, 22.2, 22.3; 12, 12.1, 12.2, 12.3) of the other fastening part (2, 1), wherein the fastening parts (1, 2) are prevented from being separated from one another along the placement axis (S) by the form-fitting element (11, 11.1, 11.2, 11.3; 21, 21.1, 21.2, 21.3) engaging on the engagement region (22, 22.1, 22.2, 22.3; 12, 12.1, 12.2, 12.3).

[0003] Locking device with two locking parts

[0004] Description

[0005] The proposed solution concerns a locking device with two locking parts.

[0006] Locking devices with two interlocking locking parts are widely known in various forms. For example, EP 3 292 785 A1 discloses a locking device in which two locking parts can be attached to one another along an insertion axis and are automatically moved into a locked position by magnetic force, in which the two locking parts can no longer be separated from each other without rotating them around the insertion axis. The locking device of EP 3 292 785 A1 is thus suitable, for example, for a jewelry clasp to quickly connect and lock two parts to be joined together. However, the automatic, magnetically driven adjustment of the locking parts to a locking position immediately after the two locking parts are attached to one another may not be advantageous for other applications and may also hinder the quick opening of the clasp.

[0007] There is therefore still a need for alternatively designed locking devices that can be used to connect two parts.

[0008] Against this background, according to a first aspect of the proposed solution, a locking device for joining two parts is provided, comprising a first locking part and a second locking part. Each of the locking parts has

[0009] P 0344 WO IV FID444WO Page 2 shows a load-bearing section designed for connection to a portion of the parts to be joined. The first and second locking parts can be attached to and connected along an attachment axis, and in a connected state, they can pivot relative to each other about the attachment axis. Furthermore, a proposed locking device provides for an attachment position for the first and second locking parts, in which they are positioned relative to each other and connected after being attached.Only by applying a load pointing away from the insertion axis to the first and second load application sections of the first and second locking parts can the two locking parts be pivoted from the insertion position around the insertion axis into an engagement position in which at least one positive locking element of one locking part engages in an engagement area of ​​the other locking part and the first and second locking parts are locked against separation from each other along the insertion axis via the positive locking element engaging in the engagement area.

[0010] In a locking device according to the first aspect of the proposed solution, it is thus provided that, after being attached, the first and second locking parts are initially in a defined attachment position relative to each other and can be pivoted into an engagement position relative to each other by forces acting on the first and second load-bearing sections. In this position, the first and second locking parts are positively locked against separation along the attachment axis. Until a load acts on the first and second load-bearing sections of the first and second locking parts, the locking parts can therefore remain in an attachment position in which separation of the locking parts along the attachment axis is still possible. Only under load do the first and second locking parts pivot relative to each other into the engagement position.

[0011] A load application area can be defined at both the first and second load application sections, where a load is introduced into the locking device via the first or second part connected to the respective locking element. A connecting line linking the load application areas of the first and second load application sections can have a path such that it does not intersect the application axis when the first and second locking elements are in their application position. A load introduced into the locking device at the load application areas thus typically has a direction of action that is not exclusively radial to the application axis, but also always in a

[0012] P 0344 WO IV FID444WO Page 3

[0013] A force component results that runs perpendicular to the axis of attachment. Thus, via the first and second locking elements, and in particular the arrangement of the load application areas with respect to the axis of attachment, it is ensured that a load applied by the first and second elements to be joined leads to a pivoting of the first and second locking elements relative to each other.

[0014] The connecting line runs, for example, in a plane perpendicular to the insertion axis and / or at a predetermined distance from the insertion axis. If the connecting line runs at a distance from the insertion axis, this distance can be used to define the moment about the insertion axis with which the respective first or second locking element is subjected when a force is applied to its first or second load-bearing section, when the first and second locking elements are in the insertion position. The length of a (virtual) lever arm can therefore be defined by this distance, and thus the magnitude of the moment under which the first and second locking elements pivot from the insertion position to the engagement position when forces are applied to the load-bearing sections via the parts connected to the locking elements, for example, by pulling the first and second parts to be connected to the locking device apart.

[0015] In one embodiment, the connecting line is designed so that it does not intersect the insertion axis, even in the engagement position. This ensures that even after pivoting into the engagement position, a moment is still introduced in the engagement position that exceeds the load acting on the load application sections.

[0016] In this context, it may also be provided that a pivoting range of the first and second locking parts, within which the first and second locking parts can pivot about the pivoting axis in their connected state between the insertion position and the engagement position, is limited such that the connecting line linking the load application areas of the first and second load application sections never intersects the insertion axis within this pivoting range. Thus, a pivoting range is defined that ensures that the first and second locking parts cannot be adjusted relative to each other beyond a dead center.

[0017] To separate the first and second locking parts, it may be necessary to first pivot them from their engagement position relative to each other, at least into the insertion position. Separating the

[0018] P 0344 WO IV FID444WO Page 4 Therefore, separation of the first and second locking parts is only possible here if the two locking parts are swung back into the insertion position or beyond.

[0019] In a further development based on this principle, the first and second locking parts are, for example, pivotable relative to each other about the insertion axis along a pivoting direction beyond the insertion position to separate them in a T-shape. The first and / or the second locking part comprises at least one ramp section. Upon reaching the insertion position, a separation force applied to pivot the first and second locking parts can be converted into a force component acting parallel to the insertion axis by further pivoting of the first and second locking parts along the pivoting direction. Under the influence of this force component, the first and second locking parts are displaced away from each other in a direction parallel to the insertion axis. Thus, the at least one ramp section facilitates axial separation of the first and second locking parts simply by performing the pivoting movement in the direction of the insertion position and subsequently beyond.

[0020] In a further development, at least one ramp section is provided on both the first and second locking parts. The ramp sections of the first and second locking parts can interact to move the locking parts away from each other parallel to the insertion axis. In particular, such a design variant can include the at least one ramp section having an inclined ramp surface. A section of the other locking part, for example, another ramp section of the other locking part, slides onto this surface when pivoted further beyond the insertion position, and separation of the first and second locking parts is only possible once one end of the ramp surface is reached.In such a design variant, an axial displacement across at least one ramp section can be generated by the pivoting movement of the first and second locking parts relative to each other. However, this axial displacement only allows the first and second locking parts to actually separate from each other at the end of the inclined ramp surface. Until the end of the ramp surface is reached, the first and second locking parts remain at least partially positively locked to each other.

[0021] A ramp section can, for example, be formed on the positive locking element. Alternatively or additionally, a ramp section can be formed on a closure part body of the

[0022] P 0344 WO IV FID444WO Page 5 of the first or second locking part, spaced apart from the positive locking element provided on the locking part or from the engagement area provided on the locking part. The location of a ramp section can offer various advantages depending on the application, particularly with regard to where a force component acting parallel to the insertion axis is generated via the ramp surface to displace the first and second locking parts parallel to the insertion axis and thus axially away from each other when the first and second locking parts are pivoted relative to each other into or beyond the insertion position.

[0023] In one embodiment, the locking device, in the engagement position of the first and second locking parts, defines a force application surface. A separating force with a component perpendicular to the application axis can be applied to this surface. Under the influence of this separating force (after the load acting on the first and second load application sections has ceased and / or while the load continues to act on these sections), the first and second locking parts can be pivoted relative to each other from the engagement position towards the application position. The force application surface of the locking device is therefore designed and arranged such that a separating force with a component perpendicular to the application axis can be applied to it, causing the locking device to open and the first and second locking parts to pivot relative to each other towards their application position.By applying the separating force to the force application surface, the locking elements can be pivoted from the engagement position towards the insertion position, particularly when the first and second locking elements are still subjected to load at the load application sections, especially in the direction of the engagement position. This eliminates the need for a user to grasp both the first and second locking elements to pivot them relative to each other towards the insertion position and then separate them again. Instead, a force applied to the force application surface can cause the first and second locking elements to pivot relative to each other into the insertion position. This makes it particularly easy to open a closure formed by the locking device, for example, by applying force only to the force application surface.

[0024] For example, the force application area is defined by at least one surface section of both the first and second locking parts. Alternatively or additionally, a release element of the locking device is accessible at the force application area, which, under the influence of the separating force, causes the first and second locking parts to pivot.

[0025] P 0344 WO IV FID444WO Page 6

[0026] The locking components can be released from the engagement position towards the insertion position. Such a release element can, for example, be spring-loaded into an ejection position and locked in a detent position other than the ejection position when the first and second locking components are in their engagement position. If the release element's locking mechanism is released under the force of the separating force, the release element moves into the ejection position, whereby this movement causes the two locking components to pivot towards the insertion position.

[0027] In the application position, the force application surface can, for example, have a V-shaped or U-shaped cross-section, with opposing legs of the V-shape or U-shape being formed by the surface sections of the first and second locking parts inclined towards each other around the application axis.

[0028] In one embodiment, the opening angle of the legs of the V- or U-shaped locking mechanism is limited to a predetermined threshold value in the application position. Consequently, the opening angle of the legs does not fall below a predefined dimension. This threshold value can be defined by a separate separating element designed for separating the first and second locking parts. A minimum opening angle of the legs is thus precisely calibrated to a specific separating element so that the separating element can be applied to the force-application surface without jamming and is not jammed between the surface sections when the surface sections of the two locking parts are pivoted towards each other under the applied separating force, which involves a pivoting of the locking parts relative to each other in the direction of the application position.

[0029] In one embodiment, the first locking element has a first guide section and the second locking element has a second guide section. When the first and second locking elements are connected, these guide sections define a pivot bearing, allowing them to pivot relative to each other about the insertion axis – from the insertion position to the engagement position and back. Under the influence of the separating force applied to the force application surface, the first and second guide sections are adjustable relative to each other. This adjustment, in turn, is accompanied by a change in the position of the insertion axis defined by the guide sections with respect to the first and second load application sections, provided the load application sections remain loaded by the parts connected to the locking device.

[0030] P 0344 WO IV FID444WO Page 7

[0031] Alternatively or additionally, when the first and second locking parts are in the engagement position and a load is applied to the locking device at the first and second load application sections, a moment can be introduced into at least one of the two locking parts via the separating force applied to the force application surface. Under this effect, the first and / or second locking parts pivot towards the insertion position. If at least one ramp section is provided on the first and second locking parts, applying the separating force to the force application surface along a separation direction (for example, via a separate separating element guided along the separation direction) can cause the locking parts to pivot towards the insertion position. This pivoting action then also results in the complete separation of the first and second locking parts from each other by means of the at least one ramp section.Therefore, with a continuous movement along a separating direction of a separating part acting on the force application surface, the positive locking of the first and second locking parts can be released from each other, and furthermore, the locking parts can also be separated from each other.

[0032] For example, to reinforce the positive locking of the first and second locking parts to each other in the engagement position, at least one of the locking parts can comprise at least two positive locking elements which, in the engagement position, are engaged at at least two different engagement areas of the other locking part.

[0033] Alternatively or additionally, both the first and second locking parts can each have at least one positive locking element, and both the second and first locking parts can each have at least one engagement area. In such a design variant, the first and second locking parts thus interlock positively when they are in the engagement position.

[0034] In one embodiment, the first locking component comprises a first locking component body with a first side and a second side facing away from the first side. Similarly, the second locking component comprises a second locking component body with a first side and a second side facing away from the first side, wherein the two locking components can be connected to each other in two different connection variants along the attachment axis. Here, in

[0035] P 0344 WO IV FID444WO Page 8 of a first connection variant of the two different connection variants, the first side of the first locking component body faces the second side of the second locking component body when the first and second locking components are in the insertion position. In a second connection variant of the two different connection variants, the first side of the second locking component body again faces the second side of the first locking component body when the first and second locking components are in the insertion position. In such a design variant, the first and second locking components can therefore be inserted with different sides facing each other and moved from the insertion position to an engagement position.For example, one locking element can be positioned with its front facing the back of the other locking element, or vice versa. From each of these two possible positions, the locking elements can be pivoted into an engagement position under load on the load-bearing sections. This makes it easier for a user of the locking device to close a gate provided by the device, as it is irrelevant which locking element is at the front or rear with respect to an engagement direction parallel to the engagement axis.

[0036] In a possible further development, one and the same positive locking element of one closure part engages in a different engagement area of ​​the other closure part, depending on the connection variant used to join the closure parts. For example, if a positive locking element of one closure part engages in a first engagement area of ​​the other closure part when the first and second closure parts assume an engagement position achieved by pivoting around the insertion axis from the insertion position of the first connection variant, the same positive locking element engages in a second engagement area of ​​the other closure part, different from the first engagement area, when an engagement position is reached that was achieved by pivoting around the insertion axis from the insertion position of the second connection variant.

[0037] In one embodiment of a proposed locking device, it may alternatively or additionally be provided that the first and second locking parts can be connected to each other along the insertion axis both to assume a first insertion position relative to each other and to assume a second insertion position relative to each other, even if the locking parts are inserted with the same sides of their locking part bodies facing each other. In the interconnected

[0038] P 0344 WO IV FID444WO Page 9

[0039] In this configuration, the first and second locking parts can be pivoted from either of their initial positions relative to each other into the same engagement position (but along opposite pivot directions). This also simplifies the connection of the first and second locking parts, as assuming an initial position does not require a specific orientation of the locking parts relative to each other.

[0040] To facilitate the alignment of the first and second locking parts, each can include at least one magnetic element. When the locking parts are aligned, the magnetic elements attract each other to define the alignment position. However, the movement of the first and second locking parts from this magnetically assisted alignment position to the engagement position is not magnetically driven. Instead, the first and second locking parts initially remain in the alignment position when the locking device is unloaded. Only when a load is applied to the load-bearing sections of the first and second locking parts do they pivot from the alignment position to the engagement position, in which they are positively locked together.

[0041] In a possible further development, additional magnetic elements of the locking components can interact magnetically in the engagement position to counteract the locking components' pivoting from the engagement position to the application position. Consequently, if the engagement position is assumed due to the load applied to the load-bearing sections, the first and second locking components can be magnetically secured against pivoting back towards the application position. Furthermore, the additional magnetic elements can, through their magnetic attraction, ensure that the locking components are and remain in a precisely defined orientation relative to each other while the engagement position is established.

[0042] In one embodiment, it can be provided that the magnetic elements of the first and second locking parts, which attract each other magnetically when the locking parts are attached, and / or at least one further magnetic element, i.e., at least one additional magnetic element provided besides these magnetic elements that support attachment, generate a magnetic force on the connected locking parts, under the influence of which the locking parts are biased into their attachment position.

[0043] P 0344 WO IV FID444WO Page 10

[0044] The orientation of the poles of the magnetic elements supporting the locking mechanism, and / or at least one additional magnetic element, can therefore effect a magnetic force-based return from the engagement position to the locking position when no (sufficient) load acts on the locking parts to hold the first and second locking parts in their engagement position. Consequently, the engagement position is only established and maintained under load. As soon as the load is removed, the locking position is resumed.

[0045] In one embodiment, the locking device includes an additional auxiliary part that can be detachably connected to one of the locking parts a) for aligning the first and second locking parts and / or b) for separating the first and second locking parts from each other. In this embodiment, an additional, separate component is provided as an auxiliary part to facilitate the alignment and / or separation of the locking parts for the user, for example, because the locking parts are not directly accessible. Because the auxiliary part can be detachably connected to one of the locking parts, it can be removed after closing or opening a closure provided by the locking device. This also allows, for example, the use of one and the same auxiliary part for multiple locking devices.

[0046] For example, the additional auxiliary part includes a connecting head that can be detachably connected mechanically and / or magnetically to a closure part body of a closure part.

[0047] For example, the additional auxiliary part is designed and intended to hold one of the locking parts in a position in space when the locking parts are to be attached to or separated from each other. Alternatively or additionally, the additional auxiliary part can be designed and intended to apply a separating force to the locking device when the first and second locking parts are in the engagement position, in order to pivot the first and second locking parts relative to each other into the attachment position. In the latter case, the additional auxiliary part can therefore be used as a separating part as described above.

[0048] In principle, a load-bearing section can be used, for example, to connect to a flexible part, in particular a traction element and / or a part made of a textile.

[0049] P 0344 WO IV FID444WO Page 11

[0050] The load-bearing section may be designed and provided for a material, in particular a rope, a strap, a belt, a piece of fabric or cloth, or a cord, and / or a metallic part, in particular a metal wire. Alternatively, a load-bearing section may be designed and provided for a connection, in particular a rigid or articulated connection, to a rigid part, in particular a bolt, post, or rod. Furthermore, it is naturally also included that a load-bearing section of one closure part is designed and provided for a connection to a flexible part, while a load-bearing section of the other closure part is designed and provided for a connection to a rigid part. Likewise, it is possible that both load-bearing sections are each designed and provided for a connection to a flexible part or each for a connection to a rigid part.

[0051] For example, the fastening device is designed and intended for connecting two drawstrings or for connecting two tarpaulin sections or two net sections, in particular two tarpaulin sections of a tent or cover, or for connecting two net sections of a camouflage net. In this context, in particular, the proposed fastening device offers significant advantages that cannot be achieved with conventional zippers or snap fasteners.

[0052] The aforementioned embodiment of a locking device, in which the first and second locking parts can be connected to each other in two different connection variants, is obviously advantageous regardless of whether the first and second locking parts are only pivoted from an insertion position around the insertion axis into an engagement position by applying a load pointing away from the insertion axis to the first and second load application sections.Accordingly, according to a second aspect of the proposed solution, independently of the above, a locking device for connecting two parts is provided, wherein the first locking part comprises a first locking part body with a first side and a second side facing away from the first side, the second locking part comprises a second locking part body with a first side and a second side facing away from the first side, and the first and second locking parts can be connected to each other in two different connection variants, wherein in a first connection variant of the two different connection variants the first side of the first locking part body faces the second side of the second locking part body when the first and second locking parts are in the insertion position.

[0053] P 0344 WO IV FID444WO page 12, and in a second connection variant of the two different connection variants, the first side of the second closure part body faces the second side of the first closure part body when the first and second closure parts are in the insertion position.

[0054] The first and second locking parts thus form an interface on both sides of their respective locking part bodies, through which a connection of the locking parts with each other is made possible.

[0055] It has also been shown that the aforementioned embodiment of a locking device is fundamentally advantageous, in which the first and second locking parts each comprise at least one magnetic element, and the magnetic elements of the first and second locking parts interact magnetically to determine the engagement position when the first and second locking parts are placed against each other. Furthermore, by pivoting from the engagement position, the first and second locking parts assume an engagement position in which they are mechanically and / or magnetically secured relative to each other. A corresponding locking device therefore addresses a third aspect of the proposed solution.

[0056] One embodiment may provide that, in the engagement position achieved by pivoting from the insertion position, further magnetic elements of the first and second locking parts interact magnetically, in particular by magnetically attracting or repelling each other, to counteract pivoting of the first and second locking parts from the engagement position into the insertion position. Therefore, it is provided that the insertion of the first and second locking parts is magnetically assisted by initial magnetic elements of the first and second locking parts. Once the engagement position is achieved, it is secured by further, additional magnetic elements of the first and second locking parts, optionally in addition to a mechanical locking mechanism.

[0057] According to a fourth aspect of the proposed solution, a locking device for connecting two parts is provided, in which the locking device, in the engagement position of the first and second locking parts, defines a force application surface on which a separating force with a force component perpendicular to the insertion axis of the first and second locking parts can be applied, under the effect of which, when a load is applied to the first and second load application sections, the locking parts can be pivoted relative to each other from the engagement position in the direction of the insertion position in order to

[0058] P 0344 WO IV FID444WO Page 13 to separate the first and second locking parts from each other. Analogous to the design variant with a corresponding force application surface in a locking device according to the first aspect, in an independent locking device according to the fourth aspect, the definition of a force application surface ensures that the first and second locking parts in their engagement position can be separated from each other relatively easily by applying a separating force to the force application surface.

[0059] In principle, any embodiment of a proposed locking device, according to one of the aforementioned first, second, third, or fourth aspects (which can also be combined with each other), can provide a locking arrangement with at least two locking devices. In such a locking arrangement, the same first and second parts can also be connected to each other via at least two locking devices.

[0060] For example, one embodiment provides that the at least two locking devices are arranged consecutively in one spatial direction. It can then be further provided that the at least two locking devices arranged consecutively in one spatial direction can be opened successively by separating their first and second locking parts from one another. This is achieved by adjusting a separating part along the spatial direction with a separating force exceeding a threshold value to act sequentially on the locking devices. The successive locking devices can thus be opened relatively easily under the action of the separating part, similar to a zipper. Ultimately, the required separating force only needs to exceed the loads with which the individual locking devices are subjected in the direction of their respective engagement positions.The separating element could be, for example, a rod, a hook, a cord, a user's finger, or a user's hand.

[0061] The proposed solution is fundamentally defined by the attached independent claims, the aspects of which can also be combined. Possible embodiments are specified in the dependent claims.

[0062] Furthermore, the attached figures illustrate possible implementation variants of the proposed solution.

[0063] This shows:

[0065] Figures 1 A-24 show a first embodiment of the proposed solution, in which two locking parts are pivotable relative to each other in a connected state and in an engagement position a positive locking element of one locking part engages with an engagement area of ​​the other locking part in the manner of a bayonet lock and thereby prevents the first and second locking parts from separating from each other in an engagement position, wherein the locking parts can be pivoted from a magnetically assisted starting position into the engagement position by applying a tensile force to tensile means connected to the locking parts;

[0066] Figures 25A-67 show another embodiment of a proposed

[0067] A locking device in which several positive locking elements distributed around the circumference of a guide section are provided on a locking part for engagement with several engagement areas of the other locking part in the engagement position, wherein Figures 40 to 67 - analogous to Figures 17 to 24 for the first embodiment - illustrate a separation of the two locking parts from each other by applying a separating force via a separate separating part;

[0068] Figures 68A-1 10 show a third embodiment in which both locking elements and engagement areas are provided on both locking parts in such a way that the two locking parts can be attached to each other in two different connection variants and thus connected to each other;

[0069] Figures 1 11 A-135 show another variant in which the two

[0070] The locking parts can not only be attached to each other in two different connection variants, but for each connection variant, attachment in two different positions is also possible, so that the locking parts from two different positions can be positioned relative to each other – under the application of a load via the two tensioning elements.

[0071] P 0344 WO IV FID444WO page 15 one and the same engagement position can be pivoted, whereby the locking components shown here are designed as identical parts by way of example;

[0078] Figures 144A-144D show a further development based on the embodiment shown in Figures 1 11 A to 135, in which an additional auxiliary part is provided for holding a closure part in a specific position during connection with the other closure part;

[0080] Figures 145A-145D show a further development based on the embodiment variant of Figures 144A to 144D, in which the auxiliary part for applying the separating force is provided on the locking device;

[0081] Figures 146A-154C show a further embodiment in which, on the first and second locking parts, not only are first and second magnetic elements provided for magnetically assisted attachment of the locking parts to one another and the specification of the attachment position, but additional magnetic elements are provided to magnetically secure the engagement position of the first and second locking parts to one another.

[0082] Figures 1A to 24 show a first embodiment of a proposed locking device V, in which two locking parts 1 and 2 are magnetically connected along an alignment axis S to assume an alignment position relative to each other. Under the influence of a load on the two connected locking parts 1, 2 by means of the attached tension elements Z1, Z2, the connected locking parts 1, 2 can be pivoted from the alignment position into an engagement position about the alignment axis S, which thus also forms a pivot axis for the locking device V, or coincides with the pivot axis. In the engagement position, positive locking elements 11, 21 of the two locking parts 1, 2 engage reciprocally in engagement areas 12, 22. The two locking parts 1, 2 are thus secured against separation by means of these positive locking elements.

[0083] Figures 1A and 1B show exploded views of the locking device V. Each locking part 1, 2 has a locking part body 10 or 20. A load-bearing section 101 or 201 is formed on each of these locking part bodies 10, 20, which has a pull-cord channel 1010 or 2010. The corresponding pull-cord Z1 or Z2 is guided in this pull-cord channel 1010 or 2010. A thickening, forming a stop Z10 or Z20, is provided at one end of a pull-cord Z1, Z2 projecting from the respective pull-cord channel 1010 or 2010, such that pulling on the respective pull-cord Z1, Z2 indirectly exerts a tensile force on the load-bearing section 101, 201. A stopper Z10, Z20 can, for example, be formed by a node in the traction element Z1 or Z2 or by an element molded onto the respective traction element Z1, Z2.

[0084] P 0344 WO IV FID444WO Page 17

[0085] Each locking element body 10, 20 forms a guide section 100 or 200 spaced apart from a respective load engagement section 101 or 201. The two locking elements 1, 2 are brought together along the insertion axis S via their guide sections 100 and 200, as illustrated, for example, in Figures 2 to 6. Each guide section 100, 200 carries a magnetic element M1, M2. The magnetic elements M1, M2 attract each other magnetically when the locking elements 1, 2 are brought together along the insertion axis S.

[0086] Under the influence of the magnetic elements M1, M2, the locking parts 1, 2 assume the engagement position relative to each other shown in different views in Figures 7 to 11. In this engagement position, the two locking parts 1, 2 can be separated from each other along the engagement axis S, for example, if a user manually pulls both locking parts 1, 2 away from each other along the engagement axis S by applying force to the load-bearing sections 101, 201.

[0087] When the locking parts 1, 2 are connected to each other in their insertion position as shown in Figures 7 to 11, the connected guide sections 100, 200 define a pivot bearing for the locking device V, via which the locking parts 1, 2 can be pivoted relative to each other from the insertion position to an engagement position shown in Figures 12 to 16 about the pivot axis coinciding with the insertion axis S. The guide sections 100, 200 with the magnetic elements M1, M2 form a central part of the locking device V. The load-bearing sections 101, 201 project forward on both sides of this central part in a wing-like manner.

[0088] From the insertion position, the locking elements 1, 2 of the illustrated locking device V can be pivoted into the engagement position under load of the tensioning elements Z1, Z2. Thus, the tensioning elements Z1, Z2 can be subjected to opposing tensile forces F1a, F1b as shown in Figure 12. By acting on the respective tensile force F1a, F1b at the associated load engagement section 101 or 201 at a load application area B1a or B1b shown in Figure 14, which is offset from the insertion / pivot axis S, a torque M1a, M1b is introduced into the respective locking elements 1, 2 via the tensile force F1a or F1b, as shown in Figure 15.This torque M1 a, M1 b thus results in opposing pivoting movements of the locking parts 1 , 2, so that the locking parts 1 , 2 assume the engagement position in which a positive locking element 1 1 or 21 projecting radially with respect to the insertion / pivoting axis S on the guide section 100 or 200 is each completely inserted into a recess on the respective other guide section.

[0089] P 0344 WO IV FID444WO Page 18

[0090] The respective positive locking element 11, 21 engages positively in the engagement area 22 or 12 of the other locking part 2, 1, so that the locking parts 1, 2 cannot be separated from each other in the engagement position without being pivoted back into the insertion position. The locking parts 1, 2 are therefore moved into the engagement position solely by the load applied to the locking device V via the tension elements Z1, Z2 in the form of the tensile forces F1a, F1b, after the locking parts 1, 2 have been inserted against each other. Only the load with the tensile forces F1a, F1b leads to a positive locking of the locking parts 1, 2 against each other.

[0091] To pivot the locking parts 1, 2 from the engagement position back to the insertion position and to separate the locking parts 1, 2 from each other, the locking part bodies 10, 20 are provided for to form a central force application surface A adjacent to the load application areas B1 a, B1 b. A separating force FT perpendicular to the insertion / pivot axis S can be applied to both locking parts 1, 2 at this surface, causing the locking parts 1, 2 to pivot back to the insertion position. This is illustrated in Figures 17 to 21 for the first embodiment. The force application surface A is formed by surface sections 103 and 203 of the first and second locking parts 1, 2. In this design, these surface sections 103, 203 are each arranged on the upper surface of the respective locking part 1 or 2 adjacent to the respective load application area B1 a or B1 b.The surface sections 103, 203 each form legs of a V-shape or U-shape defined in cross-section, into which a separating part 3 is to be inserted to release the connection between the first and second locking parts 1, 2.

[0092] Here, the tensile force F1a and F1b, respectively, continue to act on the two locking parts 1 and 2. Both locking parts 1 and 2 are thus loaded into the engagement position. The locking device V, with its locking part bodies 10 and 20 and, in particular, the force application surface A, is designed such that, in the engagement position, pressing on the force application surface A, which is formed centrally between the load application areas B1a and B1b, introduces opposing torques M2a and M2b into the two locking parts 1 and 2 with the separating force FT, in order to pivot the locking parts 1 and 2 towards their engagement position (see, in particular, Figures 19 and 20). As the load application sections B1a and B1b pivot towards each other, the V-shape or U-shape on which the force application surface A is formed narrows. Here, the narrowing is limited to a minimum opening angle a according to Figure 20, so that the separating part 3 becomes

[0093] P 0344 WO IV FID444WO Page 19

[0094] The application of the separating force FT between the locking parts 1 and 2 prevents jamming. For example, the separating part 3 is a rod or pin intended for opening the locking device V. With the locking device V in the illustrated orientation, this rod or pin can be pressed onto the locking parts 1 and 2 from above, centrally and perpendicular to the insertion / pivot axis S, with its longitudinal side facing down, and moved downwards with a separating force FT exceeding the tensile forces F1a and F1b. This pivots the locking parts 1 and 2 relative to each other in the direction of their insertion position.

[0095] Since both guide sections 100, 200, in their connected state, have opposing ramp sections 102, 202, each forming a ramp surface inclined towards the insertion / pivot axis S, the pivoting of the locking parts 1, 2 back into the insertion position is accompanied by an axial displacement of the locking parts 1, 2 relative to each other. Thus, during a pivoting movement about the pivot axis S in the direction of the insertion position, the ramp sections 102, 202 slide towards each other. Under the influence of the separation force FT, a force is consequently introduced into the locking parts 1, 2, under the influence of which the first and second locking parts 1, 2 are displaced away from each other in a direction parallel to the insertion / pivot axis S. This assists the separation of the locking parts 1, 2 against the magnetic force applied via the magnetic elements M1, M2.

[0096] If the separating part 3 is guided further along the separation direction perpendicular to the insertion / pivoting axis S, the locking parts 1 and 2 of the locking device V are pivoted back to their original insertion direction and beyond. Under the action of the ramp surfaces 102, 202 sliding against each other, the locking parts 1, 2 are axially displaced from each other by a defined distance when the positive locking elements 11, 21 are no longer engaged with the engagement areas 22, 12 of the respective other locking part 2, 1. The locking parts 1, 2 can thus be completely separated from each other by the separating part 3, so that the two tensioning elements Z1, Z2 are no longer connected to each other. This state is illustrated in Figures 22A to 24.

[0097] Figures 25A to 67 show a further embodiment of a locking device V, in which several positive locking elements 11.1, 11.2, 11.3 are provided on one of the locking parts 1, 2 – here the first locking part 1 – distributed around the circumference of a guide section 100. In the connected state of the

[0098] P 0344 WO IV FID444WO Page 20 first and second locking parts 1 , 2 these form-locking elements 11.1 , 11.2 , 1 1.3 can each engage in an associated engagement area 22.1 , 22.2 or 22.3 in a form-locking manner when the first and second locking parts 1 , 2 are pivoted from the insertion position to the engagement position by pulling on the pull elements Z1 , Z2.

[0099] The engagement areas 22.1, 22.2 and 22.3 are arranged radially outside the guide section 200 of the second locking part, which contains the magnetic element M2. Thus, the engagement areas 22.1, 22.2, 22.3 are provided in radially outside recesses of the locking part body 20 at the edge of an opening in the (second) locking part body 20, into which the guide section 100 of the first locking part 1 can be inserted when the two locking parts 1, 2 are brought together along the insertion axis S (and subsequent pivot axis of the locking parts 1, 2).

[0100] Each of the positive locking elements 110, 110.2 and 110.3 of the first locking part 1 and each engagement area 220.1, 220.2 and 220.3 of the second locking part has ramp sections 110 and 220 respectively inclined to the insertion axis S. These ramp sections 110 and 220 slide onto each other when the first and second locking parts 1 and 2 are pivoted from the engagement position back into the insertion position, in order to convert the separation force FT applied to separate the locking parts 1 and 2 into a force component that leads to an axial displacement of the first and second locking parts 1 and 2 away from each other. The function of the ramp sections 1, 10 and 220 is therefore identical to the embodiment described above in Figures 1A to 24. In contrast, however, the ramp sections 110, 220 of the embodiment shown in Figures 24A to 67 are designed in the area of ​​the guide sections 1, 10, 220.In addition, several such ramp sections 110, 220 are provided for each closure part 1 , 2.

[0101] Figures 25A and 25B show an exploded view of the second embodiment of the locking device V, where functionally identical components are identified by identical reference numerals. Figures 26 to 32 then illustrate, analogous to the embodiment described above, the positioning of the first and second locking parts 1, 2 along the positioning axis A. After this positioning, the locking parts 1, 2 are in the positioning position relative to each other as illustrated in Figures 33 to 39. In this positioning position, none of the positive locking elements 11.1 to 11.3 are in positive engagement with their respective associated engagement areas 22.1, 22.2, or 22.3. A corresponding engagement of the positive locking elements 11.1 to 11.3 in the

[0102] P 0344 WO IV FID444WO Page 21

[0103] The engagement areas 22.1 to 22.3 are only activated by pulling on the tension elements Z1, Z2 with the tension forces F1a, F1b, causing the locking parts 1, 2 to pivot relative to each other into the engagement position. This engagement position is shown in Figures 40 to 46, here again with a separating part 3 already attached to the engagement surface A.

[0104] If the separating element 3 is pressed perpendicular to the insertion / pivot axis S, as shown in Figures 47 to 53, with a sufficiently high separating force FT against the force application surface A, and thus against the two surface sections 103, 203 of the first and second locking parts 1, 2, while the tensioning elements Z1, Z2 continue to be subjected to the tensile forces F1a, F1b against each other, the insertion / pivot axis S is pressed with the separating force FT in the direction of action and thus in the separation direction; in this case, the insertion / pivot axis S moves "downwards". The locking parts 1, 2 are thereby pivoted relative to each other in the direction of their insertion position. This pivoting movement causes the surface sections 103, 203 to pivot towards each other, but again only up to the minimum opening angle a, so that the separating element 3 cannot become jammed between the surface sections 103, 203.

[0105] As the locking parts 1, 2 pivot towards the insertion position, the ramp sections 1 10, 220 slide towards each other again. The first and second locking parts 1, 2 are thereby displaced axially from each other once more, after the positive locking elements 1 1.1 to 1 1.3 have been completely disengaged from their associated influence areas 22.1 to 23.3. This is illustrated in Figures 54 to 60. Figures 61 to 65 then show the completely separated state of the first and second locking parts with the separating part 3 still moving along the separation direction.

[0106] Figures 66 and 67 show the second closure part 2 corresponding to the section lines CC and DD of Figure 65. In particular, the inner engagement areas 22.1, 22.3 and 22.3, adjacent to the guide section 200, are shown again.

[0107] 22.3 with the ramp sections 220 visible within the closure part body 20.

[0108] Figures 68A to 110 show a further embodiment of the locking device V according to the proposed solution. In this embodiment of the locking device V, the first and second locking parts 1 and 2 are each equipped with either positive locking elements 11.1-11.3 or 21.1-11.1.

[0109] 21.3 as well as with engagement areas 12.1-12.3 or 22.1-22.3. Thus, on the first closure part 1, 1 A are distributed circumferentially on a first side.

[0110] P 0344 WO IV FID444WO Page 22

[0111] Positive locking elements 1 1.1 - 1 1.3 are formed on a projecting guide section 100. On a second side 1 B, facing away from the first side 1 A, a recess is provided for inserting a guide section 200 of the second locking part 2. On this recess, engagement areas 12.1 - 12.3 for the positive locking elements 21.1 - 21.3 of the second locking part 2 are provided radially outside.

[0112] In the embodiment shown in Figures 68A to 110, it is possible to attach and connect the two closure parts 1 and 2 in two different ways. The second closure part 2, with its first side 2A, on which the guide section 200 projects axially, can be attached to the second side 1B of the first closure part 1A. This inserts the guide section 200 of the second closure part, with its radially outwardly projecting positive locking elements 21.1–21.3, into the recess accessible on the second side 1B of the closure part body 10 of the first closure part 1. By pivoting the first and second closure parts relative to each other into the engagement position by pulling on the tension elements Z1 and Z2, the positive locking elements 22.1–22.3 then engage in the engagement areas 12.1–12.1.3 of the first locking part each engage a rim 121 of the recess and thus lock the first and second locking parts 1 , 2 together in a form-fitting manner.

[0113] Alternatively, the first and second locking parts 1, 2 can also be positioned and connected to each other in a different connection variant such that the first side 1A of the first locking part 1, with its axially projecting guide section 100, is inserted into the recess of the locking part body 20 of the second locking part 2, accessible on the second side 2B. If, in this positioning position, the first and second locking parts 1, 2 are pivoted into the engagement position by pulling on the tension elements Z1, Z2, the positive locking elements 11.1, 11.2, and 11.3 of the first locking part 1 each engage an edge 212 of the recess on the second locking part 2 at an engagement area 22.1, 22.2, or 22.3, in order to positively lock and hold the first and second locking parts 1, 2 together.

[0114] Figures 68A to 110 show, in views corresponding to Figures 25A to 67, the joining of the first and second locking parts 1 , 2 to each other and their separation from each other for the connection variant mentioned above, in which the guide section 200 of the second locking part 2 engages in the recess on the second side 1 B of the first locking part 1.

[0115] P 0344 WO IV FID444WO Page 23

[0116] In the embodiment shown in Figures 11 1 A to 135, the two locking parts 1, 2 of a locking device V, according to the proposed solution, can not only be attached to one another in two different connection variants, i.e., with different arrangements of the first and second locking parts 1, 2 along an attachment direction. Rather, for each of the two possible connection variants, attachment in two different positions is also possible, so that the locking parts 1, 2 can be pivoted from either of these different positions into the same engagement position relative to each other by pulling on the pull rods Z1, Z2. In contrast to the embodiments described above, the locking parts 1, 2 are also designed here as identical parts in order to save manufacturing costs.

[0117] In contrast to the embodiments described above, the load-bearing section 101, 201 of the locking parts 1, 2 of embodiment 1 11 A to 135 is each designed as a tab with a pull-out opening 1010 or 2010. Furthermore, analogous to the embodiment described first in Figures 1 A to 24, in embodiment 11 1 A to 135, only exactly one positive locking element 11 or 21 is formed for each locking part 1 or 2 in the form of a web projecting radially from the respective guide section 10 or 20. However, both locking parts 1, 2 have an engagement area 12.1, 12.2 or 22.1, 22.2 both above and below the respective guide section 10 or 20 with respect to the mounting / pivot axis S. An intervention area 12.1, 12.2 or 22.1, 22.2 is formed on a wall between the respective load application section 101 or 201 and the guide section carrying the respective magnetic element M1 or M2. Thus, on both sides of a closure part body 10 or 20, the possibility is provided that a projecting positive locking element 21 or 11 of the respective other closure part 2 or 1 can engage positively in an engagement area 22.1 or 22.2 respectively 12.1 or 12.2 when the closure parts 1, 2 are pivoted into an engagement position relative to each other. In the respective engagement position, the form-locking element 1 1 or 21 engages an edge 221 or 121 behind the closure part body 20 or 10 of the other closure part 2, 1 in order to secure the two closure parts 1 , 2 against separation from each other (see in particular Figures 1 13, 1 15, 1 19, 123 and 127).

[0118] Furthermore, by enabling the two locking parts 1, 2 to be magnetically assisted and aligned in two different starting positions, the two locking parts 1, 2 can also be pivoted from two different starting positions into exactly the same engagement position, but then along

[0119] P 0344 WO IV FID444WO Page 24 different pivot directions. For example, if, as shown in Figure 118, the two locking parts 1, 2 are positioned in a first engagement position, the first locking part 1 must be pivoted counterclockwise and the second locking part 2 clockwise to assume the engagement position. In another possible engagement position, the first and second locking parts would be rotated by 90° with the tensioning elements Z1, Z2, so that the first locking part 1 would have to be pivoted clockwise and the second locking part 2 counterclockwise about the engagement / pivot axis S to assume the engagement position.

[0120] Furthermore, Figures 111A to 135, in views and sequences corresponding to Figures 68A to 110, illustrate the joining of the locking parts 1, 2 to one another (Figures 111A to 115), the assumption of the joining position (Figures 116 to 119), the transfer of the locking parts 1, 2 into the engagement position by pulling the pulling elements Z1, Z2 away from each other (Figures 120 to 123), the attachment of a separating element 3 to a force application surface A of the locking parts 1, 2 in the engagement position (Figures 124 to 127), the pivoting of the locking parts 1, 2 back into the joining position under the action of the trending element 3 (Figures 128 to 131), and the final complete separation of the locking parts 1, 2 from each other by the moving separating element (Figures 132 to 135).

[0121] Figures 136A, 136B and 136C show the locking device V of Figures 1 11 A to 135 in a first connection variant, in which the second locking part 2 is arranged in front of the first locking part 1, in corresponding views during the insertion, the engagement position and the pivoting back into the insertion position under the action of the separating part 3.

[0122] Figures 137A, 137B and 137C show, in views corresponding to Figures 136A to 136C, the second connection variant in which the first locking part 1 is arranged in front of the second locking part 2, but the locking parts 1 , 2 are in a corresponding insertion position relative to each other after being attached, as in the embodiment variant of Figures 136A to 136C.

[0123] Figures 138A, 138B and 138C as well as 139A, 139B and 139C again show the first and second connection variants with a second attachment position of the first and second locking parts 1, 2 relative to each other. Here, a pivoting of the locking parts 1, 2, which are in the engagement position, into their attachment position and the separation are shown.

[0124] P 0344 WO IV FID444WO page 25 of the locking parts 1 , 2 are separated from each other by a separating part 3 which is moved in the opposite direction of separation, i.e. upwards (and not downwards as in the embodiment variants of Figures 136A-136C and 137A-137C).

[0125] Figures 140A and 140B each show a side view of a further embodiment of a proposed locking device V, illustrating a connecting line g that links the load application areas B1a and B1b. The connecting line g is spaced apart from the pivot axis S of the locking device V, which forms the pivot axis, over the entire permissible pivot range between the application position and the engagement position. This geometric arrangement is also implemented in the embodiments described above, so that in the application position, by pulling the load application sections 101 and 201 away from each other, the locking parts 1 and 2 can be pivoted into their engagement position, in which the positive locking between the locking parts 1 and 2 is then established.

[0126] In the embodiment shown in Figures 140A and 140B, the connecting line is exemplarily spaced at a distance h1 from the mounting / pivot axis S, such that a lever arm is defined over this distance h1 for the torques M1a or M1b resulting from pulling on the load application sections 101 or 201 with a tensile force F1a or F1b. The arrangement of the load application areas B1a, B1b with respect to the guide sections 100, 200, respectively the pivot bearing formed therewith when the locking parts 1, 2 are connected, and the pivot axis S defined therein, thus ensures that, when the locking device V is used as intended and a load is applied to the load application areas B1a, B1b, the locking parts 1, 2 are moved into the engagement position.

[0127] In views corresponding to Figures 140A and 140B, Figures 141A, 141B, and 141C illustrate the separation of the two locking parts 1, 2 from one another by means of a separating element A acting on the force application surface A of the locking device V. Here, forces FT, F1a, F1b and moments M2a, M2b acting in different phases are illustrated in Figures 141A to 141C. In particular, it can be seen from Figure 141A that a section of the force application surface A, on which the separating element 3 acts, is spaced a distance h2, measured perpendicular to the axis of application / pivot S, from the connecting line g. This ensures that the force application surface A is not affected by the force acting perpendicular to the axis of application / pivot S.

[0128] P 0344 WO IV FID444WO Page 26 acting separating part 3 the resulting torque M2a, M2b is applied to a closing part 1 , 2 when the tensile forces F1 a and F1 b continue to act on the load application areas B1 a, B1 b, even before the insertion / swivel axis S is displaced in the separation direction under the action of the separating part 3.

[0129] Figures 142A to 142D illustrate a closure arrangement VA in which several (possibly identical) closure devices V are arranged in a row, one behind the other or one above the other, along a spatial direction, in the manner of a zipper. Two textile edge pieces RS1 and RS2 are connected to each other by the row of closure devices V. The first pull tab Z1, held on the first closure part 1, is fixed to a first textile edge piece RS1, while the second pull tab Z2, held on the opposite, second textile edge piece RS2, is fixed to the second closure part 2. The row of closure devices V is arranged in a gap between the two textile edge pieces RS1 and RS2, such that the two edge pieces RS1 and RS2 are connected to each other via pairs of closure parts P1 to P5 of the row of closure devices V.The locking devices V can be designed in particular according to an embodiment shown in the figures above.

[0130] By connecting the textile edge pieces RS1 and RS2 under tension via the fastening devices V, the tension elements Z1 and Z2 are each biased away from each other, and the fastening element pairs P1 to P5 are each moved into their engagement position. Due to the aforementioned design of the fastening devices V, a separating element 3 can now be pulled through the gap from above with a separating force FT. Each time the separating element 3 acts from above on a force application surface A of a fastening device V, the corresponding fastening element pair P1 to P5 is pivoted into the engagement position and then separated from each other. The fastening arrangement VA can thus be opened relatively easily with the individual separating element 3, similar to a zipper, and the textile edge pieces RS1 and RS2 can therefore be separated from each other.

[0131] The textile edge sections RS1 and RS2 could, for example, be sections of a tent tarpaulin, cover, or camouflage net. With the illustrated closure arrangement VA, these sections can be joined together and separated relatively quickly and easily.

[0132] P 0344 WO IV FID444WO Page 27

[0133] This principle also applies to the further development shown in Figures 143A to 143D. In contrast to the embodiment shown in Figures 142A to 142D, the only difference is that each locking device V of a locking element pair P1 to P5 is equipped with a release element 4, which the separating element 3 only needs to act upon from above to trigger the separation of a locking element pair P1 to P5. A corresponding release element 4 can, for example, be spring-loaded into an ejection position and locked in a detent position other than the ejection position when the first and second locking elements 1, 2 are in their engagement position. When the release element 4 is released under the influence of the separating force FT, the release element 4 moves into the ejection position, and this movement causes the two locking elements 1, 2 to pivot in the direction of the engagement position.The release element 4 does not necessarily have to be spring-loaded. The decisive factor is solely that, under the influence of the separating force FT on the release element 4, the release element 4 can be displaced on the firing device V, thereby triggering an adjustment of the first and second locking parts 1, 2 of a locking part pair P1 to P5 into the engagement position.

[0134] Figures 144A to 144D show a further development based on the embodiment shown in Figures 11A to 135, in which an additional auxiliary part 5 is provided for holding one of the locking parts 1, 2 in a specific position during connection with the other locking part. In the illustrated embodiment, the auxiliary part 5 is designed to hold the first locking part 1. For this purpose, the auxiliary part 5 has a rod 51 as a force application section for a user and a connecting head 50 at its end. The connecting head 50 can magnetically attract the magnetic element M1 of the first locking part 1. This allows a user to hold the locking part 1 in position via the auxiliary part 5 without having to manually grasp the first locking part 1 directly.

[0135] For example, the auxiliary part 5, as shown in Figure 144A, can first be brought with its connecting body 50 to the locking part body 10 of the first locking part 1 (Figure 144A) and magnetically connected to it (Figure 144B). Subsequently, the first locking part 1 is attached to the second locking part 2 via the auxiliary part 5 (Figure 144C). Once the first and second locking parts 1, 2 have been pivoted into the engagement position by the tensile forces F1a and F1b acting on them via the tensile elements Z1, Z2, the auxiliary part 5 can be removed from the first locking part 1 (Figure 144D).

[0136] P 0344 WO IV FID444WO Page 28

[0137] Conversely, the auxiliary part 5 can also be used independently (or alternatively, only) to separate the two locking parts 1, 2 from each other. First, the auxiliary part 5 is brought into contact with the locking parts 1, 2, which are in their engagement position relative to each other (Figure 145A), and its connecting head 50 is connected to the first locking part 1 (Figure 145B). By pulling on the rod 51, the separation force FT can then be introduced into the locking device V, so that the insertion / pivot axis S shifts in the direction of action of the separation direction FT (here, therefore, the separation direction pointing downwards in Figures 145A-145D) – while the tensile forces F1a, F1b continue to be applied – and thus the locking parts 1, 2 are pivoted into the insertion position until they are separated from each other (Figure 145C). The auxiliary part 5 is then removed from the first closure part 1 (Figure 145D).

[0138] Figures 146A to 154C show a further embodiment of a locking device V according to the proposed solution, in which the first and second locking parts 1, 2 are not only provided with first magnetic elements M1 and M2 for magnetically assisted engagement of the locking parts 1, 2 and the specification of the engagement position. Rather, the locking parts 1, 2 of the locking device V of Figures 146A to 154C are provided with further, second magnetic elements M11 and M22. These further magnetic elements M11 and M22 together form orientation magnets that interact magnetically, at least in the engagement position, in order to magnetically secure the engagement position of the locking parts 1, 2.

[0139] The embodiment shown in Figures 146A to 154C builds upon the embodiment shown in Figures 11A to 135, so that here too the locking parts 1, 2 can be connected in two different alignment positions relative to each other and then pivoted from either of these two alignment positions (by pulling on the tension elements Z1, Z2) into the engagement position. In the engagement position, a positive locking element 11 of the first locking part 1 engages in an engagement area 22 of the second locking part 2. Furthermore, in the engagement position, a positive locking element 21 of the second locking part 2 engages in an engagement area 12 of the first locking part 1.

[0140] As illustrated in particular by the sectional views in Figures 150A, 150B, 150C, 154A, 154B and 154C, the orientation magnet M11 is arranged in the positive locking element 11 of the first locking part 1. This orientation magnet M11 of the positive locking element 11 of the first locking part 1 acts in the engagement position.

[0141] P 0344 WO IV FID444WO Page 29 magnetically attracts the orientation magnet M22 in the locking part body 20 of the second locking part 2. In this way, the two locking parts 1, 2 can only be pivoted from their engagement position back towards an engagement position by overcoming the magnetic force exerted by the orientation magnets M11 and M22. The engagement position, in which the locking parts 1, 2 are mechanically secured against separation, is thus magnetically secured here by the orientation magnets M11 and M22.

[0142] The interaction of the orientation magnets M11 and M22 ensures that the first and second locking parts 1, 2 are in a clearly defined engagement position relative to each other and remain there, even if the tensile forces F1a, F1b decrease or even cease. Therefore, an externally applied separating force FT, exceeding the magnetic attraction of the second magnetic elements / orientation magnets M11 and M22, is always required to pivot the two locking parts 1 and 2 of a locking device V of Figures 146A to 154C back towards an engagement position.

[0143] As shown by the following claims and the accompanying figures, the proposed solution is not limited to the details depicted in the figures. Rather, different aspects of the proposed solution can be implemented and combined in various ways.

[0144] In principle, a fastening device V or a fastening arrangement VA can be designed and provided for connecting two tensioning elements Z1, Z2 and / or two parts RS1, RS2 made of a textile material, in particular a rope, a band, a strap, a piece of fabric or a cord, or for connecting to a rigid part, in particular a bolt, a post or a pole. This includes the possibility that one fastening part 1 or 2 is connected to a flexible part and the other fastening part 2, 1 is connected to a rigid part. For example, a proposed fastening device V and a fastening arrangement formed by it can form a fastening on a tent tarpaulin, a cover, or a net, in particular a camouflage net.
