Description

Technical Field

[0001] The invention relates to a connection device according to the preamble of claim 1 . Background Art

[0002] The connection device comprises a first connection piece associated with a first component, the first connection piece having a first base body and an engagement device with at least one engagement protrusion. The connection device also comprises a second connection piece associated with a second component, the second connection piece being pluggable to the first connection piece, the second connection piece having a second base body having at least one engagement section rigidly arranged at the second base body. The at least one engagement section can engage with the engagement device of the first connection piece, so that in the connected position, the first connection piece and the second connection piece are held on each other.

[0003] The connection device is designed as a magnetic connection device. For this purpose, the first connection member has a first magnetic device, and the second connection member has a second magnetic device. The first magnetic device and the second magnetic device act together magnetically to assist the first connection member and the second connection member to be attached to each other.

[0004] In the locking device known from EP 3 616 553 A1 for releasably connecting two parts, a first connecting piece can be attached to a second connecting piece in order to connect the connecting pieces to each other. Here, a lace is provided at one of the connecting pieces, which can be tightened by connecting the connecting pieces to each other.

[0005] A locking device is known from EP 3 192 388 B1, in which a first connecting part has a rigid engagement projection and can be connected to a second connecting part. A strap is adjustably arranged on the second connecting part.

[0006] In the connection device, a first connecting element is associated with a first component. In contrast, a second connecting element is associated with a second component. By closing the connection device, i.e. by attaching the connecting elements to each other, the components can be connected to each other. One or both of the components can be designed, for example, by material sections, for example made of textile material, leather material or also plastic surface sections, for example by sections of a belt or clothing, wherein this is not mandatory and it is also conceivable that one or both of the components are formed by a rigid object.

[0007] A connecting device is known from JPS 57186307 A, in which connecting pieces are sewn to associated material sections. One of the connecting pieces has a pin which can be inserted into an associated opening at the other connecting piece in order to connect the connecting pieces.

[0008] A button is known from CN110063548A, which is arranged on a material section and sewn to the material section. A magnetic element is arranged on the button. Summary of the invention

[0009] The object underlying the present invention is to provide a connecting device which enables components to be securely connected to one another while producing the connection between the components and the associated connecting elements in a simple, space-saving and cost-effective manner.

[0010] This object is achieved by the subject matter having the features of claim 1 .

[0011] Thus, the first base body has a first stitching area for establishing a first stitching portion for connection with the first component, wherein the first stitching area extends along a first plane and, viewed along the first plane, the first stitching area has a smaller spacing from the first magnetic device than at least one engaging projection in at least one section. Additionally or alternatively, the second base body has a second stitching area for establishing a second stitching portion for connection with the second component, wherein the second stitching area extends along a second plane and, viewed along the second plane, the second stitching area has a smaller spacing from the second magnetic device than at least one engaging section in at least one section.

[0012] In the connection device, the first connector can be sewn with the first component, and / or the second connector can be sewn with the second component. Therefore, the first connector can have a first sewing area, at which, through or in which it can be sewn with the help of a needle and thread, so as to establish a sewn connection between the first connector and the associated first component. In conventional use (after connection with the associated component), there is a sewn connection between the first connector and the associated first component via sewing established with the first sewing area. Additionally or alternatively, the second connector can have a second sewing area, at which it can be sewn with the help of a thread, so as to establish a sewing for connecting between the second connector and the associated second component. In the conventional configuration state, there is a sewn connection between the second connector and the associated second component via sewing established with the first sewing area.

[0013] By arranging the stitching for connecting the first connecting element to the associated first component and / or the stitching for connecting the second connecting element to the associated second component at the respective base body in a close positional relationship relative to the magnetic means of the respective connecting element - compared to the engagement projection or engagement section - a stitched connection with small spatial dimensions is obtained between the respective connecting element and the associated component. By establishing the connection via the base body instead of an outwardly protruding flange, the area over which the stitching extends (also referred to as the footprint) can be relatively small.

[0014] By means of a stitched connection of the respective connecting element to the associated component in a spatially relatively narrow positional relationship to the respectively associated magnetic device, a force transmission is obtained between the connecting element and the associated component in a spatially narrow positional relationship to the magnetic device, which is arranged, for example, centrally on the respective connecting element. The stitching is spatially arranged, for example, between the magnetic device and at least one engagement projection or engagement section, so that a favorable force flow is obtained between the component and the connecting element arranged therebetween.

[0015] The connection of the respective connecting element to the associated component can be produced simply and cost-effectively by sewing, wherein such a sewing connection can be implemented in a load-bearing manner and achieves a close positional relationship between the respective connecting element and the associated component. In addition, sewing is also possible on small surfaces, in particular on narrow strips such as are used on bicycle helmets.

[0016] It is conceivable that, at the location of the sutured connection, for example by selecting and dimensioning the sutures, a desired breaking point is achieved, which tears when a certain load force is exceeded. Thus, when a predetermined load force is exceeded, the connection part is separated from the associated component due to the tearing of the suture, which can be useful, for example, in the case of excessive loads, for example when used in airbags, in order to achieve an emergency separation.

[0017] The first component and / or the second component can be formed, for example, by soft material segments, for example made of textile material, leather material, plastic surface segments and other materials. The first component and / or the second component can be formed, for example, by a belt, by a strip, by a part of clothing, by a part of a bag, a backpack or other container or by completely different components.

[0018] Such material sections can have completely different material thicknesses, wherein in the case of greater material thicknesses or in the case of harder materials the material can be perforated for the placement of sutures.

[0019] However, the first component and / or the second component can also be formed by a solid object, for example by a plastic component.

[0020] In the connection device, one or two of the connectors can be connected to the respectively associated components via a suture connection. In order to establish the suture connection, the suture thread is guided through the suture area at the corresponding substrate so as to establish sutures between the corresponding connector and the associated component in the described manner so as to connect the connector to the component.

[0021] The first substrate or the second substrate having a suture area should be understood as the corresponding substrate having a suture hole arrangement or an area in which the suture hole can be arranged. The suture hole can be predefined at the suture area. However, when suture is established by a needle, the suture hole can also be formed at the suture area by piercing the suture area, wherein the substrate is designed in the suture area so that the substrate can be pierced by a needle, for example, in the suture area, the substrate has a thin part that can be pierced or the suture area is formed by a soft material, such as a membrane material or a fabric material. The thin part that can be pierced should be composed of a sufficiently tough material, that is, piercing does not cause brittle fracture.

[0022] The spacing is measured along the first plane between the first magnetic device and the first stitching area on the one hand and between the first magnetic device and at least one engaging protrusion on the other hand. Here, the spacing can be measured in particular between the center of the first magnetic device and the first stitching area or between the center of the first magnetic device and at least one engaging protrusion. It should be understood that at least one section of the first stitching area has a smaller spacing from the first magnetic device than at least one engaging protrusion, and that at least a portion of the first stitching area is closer to the first magnetic device than at least one engaging protrusion (viewed along the first plane). In order to determine this, a (imaginary) circle can be drawn in the first plane around the center of the first magnetic device, the circle having a radius corresponding to the spacing between the center of the first magnetic device and at least one engaging protrusion. If at least a portion of the first stitching area is within the circle, the portion has a smaller spacing from the center of the first magnetic device than at least one engaging protrusion.

[0023] In this case, the distance between the first magnetic device and the at least one engagement projection is measured between the center of the first magnetic device and the radial inner edge of the at least one engagement projection.

[0024] The spacing is measured along the second plane between the second magnetic device and the second stitching area on the one hand and between the second magnetic device and at least one joining section on the other hand. In this case, the spacing can be measured in particular between the center of the second magnetic device and the second stitching area or between the center of the second magnetic device and at least one joining section. It should be understood that at least one section of the second stitching area has a smaller spacing from the second magnetic device than at least one joining protrusion, that at least a part of the second stitching area is closer to the second magnetic device than at least one joining section (viewed along the second plane). In order to determine this, a (imaginary) circle can be drawn in the second plane around the center of the second magnetic device, the circle having a radius corresponding to the spacing between the center of the first magnetic device and at least one joining section. If at least a part of the second stitching area is within the circle, the part has a smaller spacing from the center of the second magnetic device than at least one joining section.

[0025] The distance between the second magnetic device and the at least one engagement portion is measured between the center of the second magnetic device and an outer edge of the at least one engagement portion.

[0026] In one embodiment, the first substrate has a first arrangement of sewing holes for establishing a first seam for connection with a first component, wherein the sewing holes in the first arrangement of sewing holes are arranged along a first plane, and when viewed along the first plane, at least some of the sewing holes in the first arrangement of sewing holes have a smaller distance from the first magnetic device than at least one engaging protrusion. Additionally or alternatively, the second substrate has a second arrangement of sewing holes for establishing a second seam for connection with a second component, wherein the sewing holes in the second arrangement of sewing holes are arranged along a second plane, and when viewed along the second plane, at least some of the sewing holes in the second arrangement of sewing holes have a smaller distance from the second magnetic device than at least one engaging section.

[0027] The first arrangement of the suture holes constitutes a first suture area, via which a first suture can be established. Additionally or alternatively, the second arrangement of the suture holes constitutes a second suture area, via which a second suture can be established.

[0028] Suture hole for example can be perpendicular to or be inclined to corresponding plane and extend through corresponding matrix.But also feasible is that suture hole for example is predefined as (not extending through matrix completely) blind hole at matrix place, and just is penetrated by suture needle when setting up suture.

[0029] If stitching holes are provided at the first base body of the first connecting element, the stitching holes are arranged relative to each other in such a way that the stitching holes are arranged one to another along a first plane and, when viewed along the first plane, the stitching holes are at least partially closer to the first magnetic device than the at least one engagement projection. Thus, at least some of the stitching holes occupy such a spatial position at the first base body that the stitching holes are closer to the first magnetic device than the at least one engagement projection. Thus, some of the stitching holes have a smaller spacing from the first magnetic device than the at least one engagement projection and, when viewed along the first plane, the engagement projection occupies a position further outward relative to the first magnetic device.

[0030] If the stitching holes are arranged at the second base body of the second connecting element, the stitching holes are arranged relative to each other in such a way that they are arranged one next to the other along the second plane and, when viewed along the second plane, they are at least partially closer to the second magnetic device than at least one joining section. Thus, at least some of the stitching holes occupy such a spatial position at the second base body that they are closer to the second magnetic device than at least one joining section. Thus, when viewed along the second plane, at least some of the stitching holes have a smaller spacing from the second magnetic device than at least one joining section, which is further outward relative to the second magnetic device.

[0031] In one embodiment, the first stitching area extends along at least one straight or curved line. Additionally or alternatively, the second stitching area extends along at least one straight or curved line. For example, the stitching holes in the first arrangement of stitching holes are arranged with each other along at least one straight or curved line. Additionally or alternatively, the stitching holes in the second arrangement of stitching holes are arranged with each other along at least one straight or curved line. Thus, the stitching holes at the corresponding connector can form a row along a straight or curved line, wherein it is also conceivable that the stitching holes extend along a plurality of straight or curved lines so that a plurality of stitches can be established for connecting the corresponding connector to the associated component.

[0032] In one design, the first stitching area extends along a plurality of lines arranged at an angle to one another. Additionally or alternatively, the second stitching area extends along a plurality of lines arranged at an angle to one another. For example, the stitching holes in the first arrangement of stitching holes are arranged along a plurality of lines arranged at an angle to one another. Additionally or alternatively, the stitching holes in the second arrangement of stitching holes can be arranged along a plurality of lines arranged at an angle to one another. Thus, the lines can constitute angled lines in the manner of polygonal lines, wherein the lines are angled relative to one another at angles not equal to 0° and not equal to 180°. Here, the individual lines can extend in a straight line or can also be curved. In particular, the lines can be connected to one another to establish a continuous stitching.

[0033] In one design, the suture holes for establishing a circumferentially closed first suture are arranged with each other in the first suture area. Additionally or alternatively, the suture holes are arranged with each other in the second suture area for establishing a circumferentially closed second suture. For example, the suture holes in the first arrangement of suture holes are arranged with each other for establishing a circumferentially closed first suture. Additionally or alternatively, the suture holes in the second arrangement of suture holes are arranged with each other to establish a circumferentially closed second suture. Therefore, the suture holes of the corresponding connector constitute a circumferentially closed row. The suture holes can be arranged with each other, for example, along a circular line so as to be circumferentially closed. In another example, the suture holes can also be arranged with each other along a polygonal line, for example a quadrilateral or polygonal polygonal line, so as to be circumferentially closed. The suture holes arranged with each other are arranged relative to each other so that a circumferentially closed suture can be established.

[0034] In one design, the first stitching area extends circumferentially around the first magnetic device as viewed along the first plane. Additionally or alternatively, the second stitching area extends circumferentially around the second magnetic device as viewed along the second plane. For example, the stitching holes in the first arrangement of stitching holes are arranged circumferentially around the first magnetic device as viewed along the first plane. Additionally or alternatively, the stitching holes in the second arrangement of stitching holes are arranged circumferentially around the second magnetic device as viewed along the second plane. Thus, the stitching holes at the corresponding connectors are arranged with each other so that the stitching holes extend circumferentially around the magnetic device of the corresponding connector, thereby forming an arrangement of the stitching holes around the corresponding magnetic device.

[0035] In one embodiment, the first base body can be attached to the first component with a first outer side extending along the first plane, wherein the first stitching area extends at the first outer side, for example in such a way that the stitching holes in the first arrangement of stitching holes are arranged with each other at the first outer side. Additionally or alternatively, the second base body can be attached to the second component with a second outer side extending along the second plane, wherein the second stitching area extends at the second outer side, for example in such a way that the stitching holes in the second arrangement of stitching holes are arranged with each other at the second outer side. The corresponding connecting element can be attached to the associated component, for example a material segment, such as a belt or other textile material or a face segment made of other materials, in such a way that the base body of the corresponding connecting element is attached to the associated component with the outer side. At the outer side, the stitching holes of the corresponding connecting element are arranged with each other, so that a stitching connection can be established between the connecting element and the associated component via the stitching holes.

[0036] It can be provided that the first base body has a first groove on a first inner side facing away from the first outer side, into which the suture holes of the first suture area open. Additionally or alternatively, the second base body can have a second groove on a second inner side facing away from the second outer side, into which the suture holes of the second suture area open. Thus, a groove is formed on the inner side of the corresponding connecting part facing away from the outer side, in which the suture holes of the corresponding connecting part can be accessed. The suture holes extend from the outer side through the base body (at least in the case of the suture to be established) to the region of the groove on the inner side, so that the suture holes can be accessed not only from the outer side but also from the inner side, so that the suture can be established by guiding the suture thread through the suture holes.

[0037] The grooves at the inner side of the respective connecting piece preferably extend along the suture holes arranged in relation to one another, thereby following the arrangement of the suture holes in relation to one another.

[0038] The groove is formed as a recess on the base body and is formed into the base body from the inside. The suture hole extends through the base body from the outside toward the inside and opens into the groove.

[0039] In one embodiment, the first groove extends circumferentially around the first magnetic device at the first inner side of the base body. Additionally or alternatively, the second groove extends circumferentially around the second magnetic device at the second inner side of the second base body. Thus, the groove circumferentially surrounds the magnetic device of the corresponding connecting piece.

[0040] The connectors can be attached to each other to connect the components and are arranged relative to each other in the connected position so that the connectors are held on each other by the magnetic interaction of the magnetic device and also by the engagement of the engagement section of the second connector with the engagement device of the first connector. In a normal state, the connectors are connected to the respectively associated components, wherein at least one of the connectors is connected to the associated component via stitching established at the stitching holes of the connector. In order to close the connection device, the connectors are attached to each other by the magnetic attraction force of the magnetic device with the assistance of magnets, so that at least one engagement section of the second connector engages with at least one engagement protrusion of the engagement device of the first connector, thereby establishing a connection between the connectors.

[0041] In order to close the connection device, the connection pieces can be attached to each other, for example, along the closing direction. Along the closing direction, the magnetic means act together magnetically so that the connection pieces are pulled toward each other with magnetic assistance.

[0042] However, attachment of the connecting element in a direction different from the closing direction is also possible here.

[0043] The connection between the connecting elements in the connected position can be play-free or play-free.

[0044] The engagement of the at least one engagement section with the at least one engagement projection in the connection position can be form-fitting or force-fitting. The at least one engagement section and / or the at least one engagement projection can in particular have surfaces extending perpendicularly to the closing direction or surfaces extending obliquely to the closing direction, which in the connection position point toward each other and establish a form-fitting or force-fitting, play-free or play-containing connection.

[0045] The retention of the connecting element in the connected position can act in the closing direction and / or in a direction pointing transversely or obliquely to the closing direction.

[0046] For example, the load direction can be oriented transversely or obliquely to the closing direction, along which the belt force acts, for example. However, the load direction can also act, for example, counter to the closing direction.

[0047] The attachment of the connecting elements to each other is assisted magnetically. For this purpose, the first connecting element has a first magnetic device and the second connecting element has a second magnetic device. The first magnetic device and the second magnetic device in particular assist in attaching the connecting elements to each other. The magnetic devices act, for example, magnetically attractingly in the closing direction, so that the magnetic devices cause a magnetic attraction force in the closing direction and pull the connecting elements toward each other in the closing direction when attached.

[0048] The magnetic devices can be formed, for example, in each case by permanent magnets. However, it is also possible that one of the magnetic devices is formed by a permanent magnet and the other of the magnetic devices is formed by a magnetic armature and thus by a passive magnetic (ferromagnetic) element.

[0049] In one embodiment, at least one engagement section is formed by an edge section, which points outwardly in a direction parallel to or obliquely to the second plane and can engage with at least one engagement projection in this direction. At least one engagement section can be formed by an edge section that surrounds the second base body and points outwardly. In another embodiment, at least one engagement section can not be formed in a surrounding manner on the base body, but for example only at the end side. In this case, the edge section can delimit the second base body outwardly when viewed along the second plane.

[0050] In such a way that the at least one engagement section can engage with the at least one engagement projection in a direction parallel to or obliquely to the second plane, the at least one engagement section and the at least one engagement projection at least partially overlap with each other when viewed in a direction perpendicular to the second plane. Via the engagement, a hold is thus (also) established between the connectors in a direction perpendicular to the second plane.

[0051] In one embodiment, when viewed along the second plane, at least one engagement section of the second connector protrudes outwardly relative to another section of the second base body. The second plane can, for example, be oriented approximately perpendicularly to a closing direction, along which the connectors can be attached to each other to close the connection device (wherein it is not excluded that the connectors can also be attached to each other in a direction different from the closing direction). At least one engagement section protrudes transversely to the closing direction from another section of the second base body of the second connector. Thus, at least one engagement section is undercut relative to a direction perpendicular to the second plane, in that the other section is recessed relative to the engagement section, thereby achieving engagement with at least one engagement projection of the engagement device of the first connector.

[0052] Here, the surface where the engagement section is recessed can extend parallel to the second plane or obliquely to the second plane. In the connected position, the engagement of the engagement section with at least one engagement projection of the engagement device of the first connecting member can be a form fit or a force fit and can be gap-free or gap-free.

[0053] The other section can, for example, constitute a fastening section, via which the second connecting piece can be attached to the associated second component and on which, for example, an arrangement of suture holes is formed. The fastening section, which is recessed relative to the joining section (viewed along the second plane), can in particular realize a second outer side, on which the suture holes are arranged in a row and with which the base body of the second connecting piece can be attached to the associated second component for connection.

[0054] In one embodiment, the at least one engagement section of the second connecting element circumferentially surrounds the second base body when viewed along the second plane. In this case, the second connecting element can in particular have a single engagement section, which extends circumferentially on the second base body and projects (radially) outwards therefrom. The engagement section is undercut in that a further section connected to the engagement section is recessed inwards relative to the engagement section, thereby enabling the engagement section to engage with at least one engagement projection of the engagement device of the first connecting element.

[0055] If the base body of the second connecting part is designed rotationally symmetrically on the pin forming the joining section, the joining section projects radially outwards and runs around the pin in a circular manner.

[0056] However, the second base body may also be designed not to be rotationally symmetrical. In this case, the joining section may, for example, surround the base body in an angular manner, for example in a quadrilateral manner.

[0057] The surfaces of the engagement section on the one hand and of the at least one engagement projection on the other hand, which face each other in the connected position and engage each other without play or with play, can be oriented along the second plane or obliquely to the second plane in order to produce a positive or non-positive connection.

[0058] Here, the connection can be established only via at least one engagement section and at least one engagement projection. However, it is also conceivable that other connection partners cooperate to establish the connection.

[0059] In one embodiment, the second base body has two engagement sections formed at edges facing away from each other. Thus, (at least) two engagement sections are formed on the base body, which are formed at different edges of the base body. The engagement sections are each undercut in that the engagement section protrudes outwards and another section of the base body connected to the respective engagement section is recessed, so that the respective engagement section can engage with an associated engagement projection of the engagement device of the first connecting element in order to close the connection device.

[0060] In one embodiment, at least one engagement projection of the first connecting member is rigidly formed on the first base body. At least one engagement section of the second connecting member can be engaged with at least one engagement projection of the first connecting member, for example, along an engagement direction pointing parallel to or obliquely to the first plane. Thus, at least one engagement projection of the first connecting member is rigidly and non-elasticly formed on the first base body of the first connecting member.

[0061] In order to close the connection device, at least one engagement projection can engage with at least one engagement section rigidly formed on the second base body of the second connection element, wherein this is preferably carried out in such a way that at least one engagement section is pushed into engagement with at least one engagement projection in an engagement direction pointing parallel to or obliquely to the first plane. Thus, in the connection position, at least one engagement section engages with at least one engagement projection (without or with play), so that via the engagement of at least one engagement section with the engagement projection, the connection elements are held in position relative to each other in a direction perpendicular to or obliquely to the first plane. The faces of at least one engagement section and of at least one engagement projection facing each other can be oriented along the first plane or also obliquely to the first plane.

[0062] Therefore, in one design, in the connecting device, one or more engaging projections are rigidly formed at the first base of the first connecting member. The second connecting member can be engaged with at least one engaging projection in such a way that at least one engaging section of the second connecting member is engaged with at least one engaging projection of the first connecting member. The first connecting member and the second connecting member are attached to each other here, for example, along a closing direction, and the magnetic device of the connecting member provides a magnetic attraction force along the closing direction so that the connecting members are attracted toward each other along the closing direction. In contrast, the engagement of at least one engaging section of the second connecting member with at least one engaging projection of the first connecting member is carried out along an engaging direction oriented transversely or obliquely to the closing direction. In the connected position, at least one engaging section is engaged with at least one engaging projection in a form-fitting or force-fitting manner so that the connecting members are held on each other.

[0063] In one embodiment, the first connecting element has a blocking section rigidly arranged on the first base body, which is designed to cooperate with the second connecting element in the connection position in order to block the engagement of at least one engagement section with at least one engagement projection against the engagement direction. When the connecting elements are attached, at least one engagement section of the second connecting element engages with at least one engagement projection of the first connecting element in the engagement direction, so that in the connection position there is a form-fitting or force-fitting connection between the connecting elements, so that the connecting elements are held on each other in a load-bearing manner by the engagement of at least one engagement section with at least one engagement projection. The engagement between at least one engagement section of the second connecting element and at least one engagement projection of the first connecting element is ensured in the connection position by a blocking section of the first connecting element rigidly formed on the first base body of the first connecting element, in that the blocking section cooperates with the associated section of the second connecting element in a blocking manner against the engagement direction, so that at least one engagement section cannot move relative to the at least one engagement projection against the engagement direction, at least not without eliminating the blocking. Thus, due to the blocking effect of the blocking section, the at least one engagement section is locked in its engagement with the at least one engagement projection.

[0064] The connecting parts are held relative to each other in the connection position due to the magnetic effect of the magnetic device, so that the connecting parts are blocked relative to each other against the joining direction by the blocking section of the first connecting part. Therefore, the connecting parts cannot be released from each other by a (pure) displacement movement against the joining direction.

[0065] In one design, in order to release the connecting pieces from each other, the second connecting piece can be tilted relative to the first connecting piece so that the second connecting piece moves relative to the first connecting piece in an inclined plane formed by the closing direction and the engagement direction, so that the second connecting piece can move relative to the blocking section in the opposite direction of the engagement direction. By tilting the second connecting piece relative to the first connecting piece, the blocking effect of the blocking section can be eliminated, so that the second connecting piece moves over the blocking section so that at least one engagement section of the second connecting piece can be disengaged from at least one engagement protrusion of the first connecting piece.

[0066] The blocking effect of the blocking section rigidly arranged on the first base of the first connecting element ensures that the second connecting element cannot move linearly against the joining direction, but can tilt in an inclined plane formed by the closing direction and the joining direction in order to separate the connecting elements from each other. The tilting movement can be performed around a defined tilting axis. However, the tilting movement can also be performed along a curved movement track located in the tilting plane, wherein the second connecting element tilts relative to the first connecting element due to the tilting movement. The tilting movement can be superimposed by a linear movement against the joining direction and / or against the closing direction.

[0067] It should be noted that in order to separate the connecting elements, the connecting elements can be tilted relative to each other. The establishment of the connection between the connecting elements is not carried out in a straight closing movement, for example, but in such a way that the connecting elements are attached to each other in a swinging manner while tilting relative to each other and move into engagement with each other. Even when the connection is established, the second connecting element can be tilted relative to the first connecting element in order to achieve engagement of at least one engagement section of the second connecting element with at least one engagement projection of the first connecting element.

[0068] In one embodiment, in the connected position, the second connecting part can be twisted relative to the first connecting part about the closing direction. This allows the connecting parts to be attached to each other with an angle tolerance. In addition, it is possible for the second connecting part to be twisted relative to the first connecting part when the connecting part is in the connected position. During the twisting, the at least one engagement section and the at least one engagement projection remain engaged. In addition, the blocking of the engagement by the blocking section also remains during the twisting. Therefore, the twisting of the connecting parts relative to each other about the closing direction in the connected position does not cause the connecting parts to be separated from each other.

[0069] The rotatability between the connecting parts in the connection position can realize any rotational movement at any angle. However, it is also conceivable that the movement of the connecting parts is limited to a predetermined rotation angle, for example, by a stop or the like. Here, the rotation angle is preferably greater than 10°, further preferably greater than 20°, particularly preferably greater than 45° or even greater than 90°.

[0070] Since the at least one engagement projection is formed rigidly and non-deformably (under normal load conditions) on the first base body of the first connecting element, the engagement projection can reliably absorb and dissipate forces when engaging with the at least one engagement section of the second base body. In this case, the at least one engagement projection is preferably formed integrally with the first base body of the first connecting element, wherein the first base body is designed as a whole to be rigid and non-deformable.

[0071] In this context, "non-deformable" is to be understood as a substantially rigid geometry and material selection of the base body, which results in that the base body of the first connecting element together with the connecting projection formed thereon does not deform under conventional loads, so that the base body is non-elastic. For example, the base body of the first connecting element can be composed of metal or a hard plastic material.

[0072] Likewise, the base body of the second connecting part together with the at least one joining section integrally formed thereon is rigid and non-deformable and, for this purpose, is made of metal or a hard plastic material, for example.

[0073] In one embodiment, the second connector can be lifted from the first connector against the closing direction on the side facing away from the at least one engagement projection so as to be tilted relative to the first connector. In the connected position, the second connector engages with the at least one engagement projection on the first base body of the first connector via at least one engagement section rigidly formed on the second base body, wherein the engagement takes place in the front region of the second connector, viewed in the direction of engagement. With the aid of the rear region with respect to the direction of engagement, the second connector can be lifted from the first connector against the closing direction in the connected position so as to tilt the second connector relative to the first connector in the manner described so as to eliminate the blocking effect of the blocking section of the first connector, so that the second connector can move relative to the blocking section of the first connector and the at least one engagement section can be disengaged from the at least one engagement projection against the direction of engagement.

[0074] In order to simplify the operation for the user, the second connecting piece can, for example, have an operating section on which the user can grip in order to tilt the second connecting piece relative to the first connecting piece. The operating section can, for example, be formed by a tab in the rear region of the second connecting piece, which the user can pull in order to lift the second connecting piece from the first connecting piece in the rear region opposite to the closing direction. However, the operating section can also be formed, for example, by a grip groove or another grip section on which the user can grip in order to tilt the second connecting piece relative to the first connecting piece in the described manner.

[0075] In one embodiment, the first connecting element has two engaging projections which are spaced apart from one another transversely to the closing direction and transversely to the engaging direction.

[0076] At least one joining section can have a curved (arc-shaped) shape. At least one joining section can be formed circumferentially on the second base body, or can alternatively be formed only on an arc section on the second base body, for example on an arc section of less than 180°. If the joining section is circumferentially on the second base body, the joining section can be circumferentially formed or can also have another shape, for example an angular shape, for example a polygonal shape, for example a quadrilateral or hexagonal shape.

[0077] In one design, at least one engagement protrusion of the first connecting member is arranged on a spring locking element that can be elastically deformed, and the spring locking element is arranged on the first base body. Therefore, at least one engagement protrusion can be spring-elastically deflected relative to the first base body.

[0078] The spring locking element can be formed, for example, by a C-shaped ring that can be elastically deformed along the first plane. In particular, the C-shaped ring can be elastically deformed so that the C-shaped ring can be elastically widened in the first plane to engage at least one engagement section of the second connector with the spring locking element formed by the C-shaped ring.

[0079] In particular, the first connector and the second connector can be attached to each other along the closing direction so that at least one engagement section of the second connector engages with the spring locking element along the closing direction, wherein at least one engagement section of the second connector can be disengaged from the spring locking element by movement along an opening direction pointing transversely or obliquely to the closing direction so that the first connector and the second connector are separated from each other for opening the connecting device.

[0080] In the embodiment, the at least one engagement projection is not rigidly arranged on the first base body, but is formed on a spring-elastic spring locking element so that it can be elastically moved relative to the first base body. The first connecting piece can be locked with at least one engagement section of the second connecting piece via the spring locking element in that the second connecting piece is attached to the first connecting piece in a closing direction so that the at least one engagement section engages with the spring locking element. In the connected position, the spring locking element surrounds the pin of the second connecting piece carrying the at least one engagement section around the closing direction so that a latching connection is established between the connecting pieces.

[0081] The surfaces of the at least one engagement section and of the at least one engagement projection that face each other can be arranged perpendicularly to the closing direction or also obliquely to the closing direction.

[0082] The connecting parts can be attached to each other in a closing direction with the help of magnets by means of magnetic devices in order to close the connecting device, while the connecting parts can be separated from each other by a relative movement in that the second connecting part is moved relative to the first connecting part in an opening direction. As a result, at least one engagement section of the second connecting part is disengaged from at least one engagement projection on the spring locking element, thereby eliminating the latching connection between the connecting parts. By the movement in the opening direction, the second connecting part is moved out of the spring locking element and disengaged from the spring locking element.

[0083] One or more engagement projections may be formed on the spring locking element. For example, an engagement projection may be formed on each leg of a spring locking element formed, for example, by a C-shaped ring. Another engagement projection may, for example, be formed on a section of the spring locking element that is centrally arranged between the legs.

[0084] In one design, at least one engagement projection of the first connecting member is movably arranged on the first base body. In particular, at least one engagement projection of the first connecting member can move relative to the first base body along the locking direction and can engage with at least one engagement section along the locking direction. If the first connecting member and the second connecting member are attached to each other in the connected position, at least one engagement projection of the first connecting member engages with at least one engagement section of the second connecting member, so that the connecting members are held on each other.

[0085] In one embodiment, the first connecting piece has a locking element that can be moved along the locking direction on the first base body, and at least one engagement projection is arranged on the locking element. In the connected position, the locking element engages with at least one engagement section of the second connecting piece via the engagement projection arranged thereon, so that a connection is established between the connecting pieces. By moving the locking element, the engagement can be eliminated so that the connecting pieces can be separated from each other for opening the connection device.

[0086] The locking element can in particular be rigidly shaped per se. However, the locking element can be moved relative to the first base body of the first connecting part along the locking direction, so that the locking element can perform a relative movement relative to the base body of the first connecting part.

[0087] The locking element can be spring-preloaded relative to the first base body of the first connecting piece, for example. The spring preload can act in particular in the direction in which at least one engagement projection of the locking element engages with at least one engagement section of the second connecting piece.

[0088] In one embodiment, the locking element has a third magnetic device, which is designed to cooperate with the second magnetic device of the second connecting member by magnetic attraction so that at least one engagement projection is engaged with at least one engagement section along the locking direction. The third magnetic device thus cooperates with the second magnetic device of the second connecting member by magnetic attraction. If the connecting members approach each other, the locking element is loaded in the direction of engagement with the engagement section of the second connecting member, so that the engagement between the engagement projection and the engagement section is established autonomously when the connecting members are attached to each other. In the connected position, due to the magnetic attraction, the locking element remains engaged with the engagement section of the second connecting member with the engagement projection.

[0089] The third magnetic device can be designed, for example, by a permanent magnet which interacts magnetically with the second magnetic device of the second connecting part.

[0090] It can be provided that the third magnetic device of the locking element and the first magnetic device of the first connecting part interact magnetically repelling each other, so that the locking element is held in the unlocked position when the connecting device is opened. If the connecting parts are brought closer together to close the connecting device, the magnetic attraction between the first magnetic device of the first connecting part and the third magnetic device of the locking element exceeds the magnetic repulsion between the third magnetic device and the first magnetic device from a certain point onwards, so that the locking element engages with the engagement projection provided thereon with the engagement section of the second connecting part.

[0091] The third magnetic device can also be designed by a magnetically passive, in particular ferromagnetic, armature which interacts magnetically attractingly with the second magnetic device of the second connecting part (in this case formed by a permanent magnet).

[0092] The connecting parts can be attached to each other in particular along a closing direction for closing the connecting device. A locking direction can be oriented in particular transversely to the closing direction, along which the at least one engagement projection can be moved relative to the first base body of the first connecting part.

[0093] Independent of the specific design of the first connecting element and the second connecting element, in particular the specific design of the at least one engaging projection of the engaging device of the first connecting element and the specific design of the at least one engaging section of the second connecting element, the connecting elements can be designed such that the second connecting element can be twisted relative to the first connecting element in the connected position about a direction perpendicular to the first plane. Thus, in the connected position, the connecting elements can be twisted relative to each other.

[0094] Other designs of the connecting element are also conceivable and feasible, in which the at least one engagement projection can be arranged rigidly or movably relative to the first main body of the first connecting element.

[0095] A system comprises a first component, a second component and a connection device according to the aforementioned type. It is proposed that a first base body of a first connecting member is sewn to the first component via a first stitching portion at a first stitching area, and / or a second base body of a second connecting member is sewn to the second component via a second stitching portion at a second stitching area.

[0096] Observed along the first plane, the first stitching part preferably has a smaller spacing from the first magnetic device than at least one engaging protrusion in at least one section. Additionally or alternatively, observed along the second plane, the second stitching part has a smaller spacing from the second magnetic device than at least one engaging section in at least one section.

[0097] The advantages and advantageous embodiments described above for the connecting device also apply analogously to this system, so that reference should be made to the above explanations here.

[0231] exist Figure 1A , Figures 1B to 5A - Figure 5G In the embodiment shown in , the connection device 1 has a first connection part 2 (the so-called female part) and a second connection part 3 (the so-called male part) to be attached to the first connection part 2 .

[0232] The connecting parts 2 and 3 can generally be attached to each other along the closing direction X, wherein the connecting parts 2 and 3 respectively have magnetic devices 21 and 31 in the form of permanent magnets (or alternatively in the form of permanent magnets on the one hand and magnetic armatures on the other hand), which act together magnetically and pull the connecting parts 2 and 3 towards each other along the closing direction X.

[0233] It should be noted that attachment of the connectors 2 , 3 is also possible in a direction different from the closing direction X, for example oriented obliquely to the closing direction X. The magnetic means 21 , 31 act together magnetically in the closing direction X and pull the connectors 2 , 3 towards each other in the closing direction X.

[0234] As according to Figure 1A and Figure 1B As can be seen in the exploded view of the first connecting element 2, the first connecting element 2 has a base body 20, which forms a receiving opening 23 for receiving the second connecting element 3. A belt receiving portion 22 in the form of a connecting piece and an opening connected thereto is provided on the base body 20, to which a belt is fastened or can be fastened. On the side facing away from the receiving opening 23, the base body 20 forms a fastening opening 25 for receiving the magnetic device 21.

[0235] The receiving opening 23 is formed as a depression on the base body 20. A bottom surface 230 in the form of a flat surface extending perpendicularly to the closing direction X is formed within the receiving opening 23, and the second connecting member 3 can be flatly abutted against the bottom surface when inserted into the receiving opening 23 to establish the connection between the connecting members 2, 3.

[0236] In the bottom surface 230 , a recess 231 is formed in the form of a depression into which—as will be described further below—a blocking element 303 engages at the base section 300 of the second connecting part 3 in the connected position of the connecting parts 2 , 3 .

[0237] The receiving opening 23 is delimited at the front end by a support section 233, which serves as a support device and load absorber for the second connecting part 3 in the connected position. A recessed opening 232 is formed between the support section 233 and the bottom surface 230, which is used to facilitate the establishment of the connection of the connecting parts 2, 3 as well as the separation, in that the edge section 305 of the base section 300 of the second connecting part 3 can be sunk into the recessed opening 232 when establishing the connection and also when separating the connection, as in the example of Fig. 5F and will be described below.

[0238] The recessed opening 232 is formed as a recessed portion relative to the bottom surface 230 and is connected to the bottom surface 230, so that the recessed opening 232 is located between the support section 233 and the bottom surface 230. An inclined transition surface 237 is formed at the transition between the recessed opening 232 and the bottom surface 230, which serves as a guide for the second connecting piece 3 for establishing a connection, as in the case of a disconnected connection.

[0239] On the rigidly designed base body 20, on the two lateral raised sections 242, 243, engagement projections 240, 241 are provided, which are rigidly formed with the base body 20 and are located above the bottom surface 230 when viewed in the height direction H pointing in the closing direction X and are used to establish a form-fitting or force-fitting connection between the connecting parts 2, 3 in the connected position. The engagement projections 240, 241 are spaced apart from one another in the transverse direction Q. The engagement projections 240, 241 together form an engagement device 24, which realizes a form-fitting or force-fitting engagement with the second connecting part 3. As will be explained below, the base section 300 of the second connecting part 3 is accommodated between the connecting protrusions 240, 241 and the bottom surface 230 in the connected position by means of the connecting section 340 formed thereon and is also supported on the supporting section 233 at the front edge 305, so that the connecting parts 2, 3 are safely and securely held on each other via this.

[0240] Sliding slopes 244 , 245 are formed at the engagement protrusions 240 , 241 , which are inclined relative to the height direction H and cause the second connection member 3 to slide away against the engagement direction Y when the connection members 2 , 3 are attached to each other along the closing direction X.

[0241] The cutout 231 is laterally delimited by arc-shaped delimiting walls 236, which together realize a blocking section of the first connecting part 2 and are oriented perpendicularly to the bottom of the cutout 231 and also perpendicularly to the bottom surface 230. The delimiting walls 236 extend in an arc shape around a central axis B of the cutout 231, which is oriented along the normal N of the bottom surface 230.

[0242] An impact ramp 235 is formed between the limiting walls 236 , which is arranged behind the support section 233 on the recess 231 and provides a sliding surface to facilitate sliding of the blocking element 303 into the recess 231 and release of the blocking element 303 from the recess 231 .

[0243] The bottom surface 230 extends flatly along a plane perpendicular to the normal direction N.

[0244] If this is based on Figure 1A , Figure 1B As can be seen in the exploded view of the second connecting element 3, the second connecting element 3 is firmly connected to an associated component in the form of a belt 4. The second connecting element 3 has a base body 30, to which the belt 4 is firmly connected by means of a seam 5.

[0245] The main body 30 can be formed in one piece and in one piece, for example, by plastic injection molding.

[0246] The base section 300 has a cylindrical basic shape and forms a base surface 302 on the side facing the first connecting part 2 (when the connection is established), which extends flat and, when the second connecting part 3 is attached to the first connecting part 2 , comes into flat contact with the bottom surface 230 in the receiving opening 23 .

[0247] A blocking element 303 with a circular cross section, which is concentric to the cylindrical base section 300 and is provided for engagement in a recess 231 on the bottom surface 230 of the main body 20 of the first connecting part 2 , protrudes from the base surface 302 .

[0248] A fastening opening 35 is formed in the blocking element 303 , which serves to accommodate a magnetic device 31 , for example in the form of a permanent magnet of the second connecting part 3 , and in which the magnetic device 31 is fastened.

[0249] The base section 300 and the joining section 340 constitute the joining device 34 of the second connecting member 3, which is used to cooperate with the joining protrusions 240, 241 of the joining device 24 of the first connecting member 2 and sink under the joining protrusions 240, 241 when establishing the connection, so that a shape-fitting or force-fitting connection is established between the connecting members 2 and 3.

[0250] In the illustrated embodiment, the joining section 340 is formed by a circumferential edge of the base section 300, which protrudes radially relative to the fastening section 301 to form an undercut, and the joining section 340 can be engaged with the joining protrusions 240, 241 of the first connecting part 2, which also form an undercut, via the undercut, so as to connect the connecting parts 2, 3 to each other.

[0251] The connection elements 2, 3 are usually attached to each other along a closing direction X, along which the magnetic means 21, 31 act together magnetically and thus pull the connection elements 2, 3 magnetically and towards each other. The connection elements 2, 3 can be brought closer to each other manually, wherein from a certain degree of approach, the magnetic attraction force autonomously engages the connection elements 2, 3 and thus causes the establishment of the connection of the connection device 1. It is thus sufficient that the connection elements 2, 3 are not attached to each other precisely, wherein the establishment of the connection then takes place as autonomously as possible.

[0252] If the connectors 2 and 3 are close to each other, as from Figure 3A-3GIt can be seen that the base section 300 of the base body 30 of the second connecting member 3 then comes into contact with the engaging projections 240, 241 from above, for example, along the closing direction X. Due to the inclined sliding ramps 244, 245 formed on the engaging projections 240, 241, the base section 300 slides off the engaging projections 240, 241, wherein the base section 300 can come into contact with the bottom surface 230 in the receiving opening 23 of the first connecting member 2 with the rear edge 304 and thus slide along the bottom surface 230 in a guided manner without prematurely getting stuck in the blocking element.

[0253] If the base section 300 slides off the engagement projections 240, 241 so that the base section 300 has passed the engagement projections 240, 241 in the closing direction X, the engagement section 340 formed at the surrounding edge of the base section 300 now engages with the engagement projections 240, 241 in the engagement direction Y with the aid of the magnetic attraction of the magnetic devices 21, 31, as shown in FIG. Figure 4A-4G The movement along the (approximate) joining direction Y is carried out in a magnetically assisted manner, wherein the load forces (introduced via the belt 4) can additionally assist in forming the joint.

[0254] If the engagement section 340 is moved in the engagement direction Y to engage with the engagement projections 240, 241, the blocking element 303 slides into the recess 231 in the receiving opening 23 of the first connecting member 2, as in the case of Figure 4A-4G Orientation Figure 2A-2G (connecting device 2 is shown in the connected position) can be seen in the transition.

[0255] exist Figure 2A-2G In the connection position shown in FIG. 2 , the blocking element 303 is inserted into the recess 231 and the base section 300 with the base surface 302 formed thereon lies flatly on the bottom surface 230 within the receiving opening 23 of the first connecting part 2 .

[0256] In the connected position, the base section 300 faces the support section 233 with the (front) edge section 305 and rests in a supporting manner on the support section 233. If forces are introduced into the second connecting part 3 via the belt 4, the forces are absorbed and dissipated by the supporting contact of the base section 300 on the support section 233.

[0257] Corresponding to the curvature of the cylindrical base section 300 , the support section 233 is curved in an arc shape about the closing direction X, so that there is contact between the edge section 305 on the base section 300 and the support section 233 along an arc-shaped support line or support surface.

[0258] The support section 233 is arranged here in a central section, viewed in the transverse direction Q, between the engagement projections 240, 241 and is spaced apart from the engagement projections 240, 241 at a central section along the engagement direction Y. The support section 233 extends arcuately below the engagement projections 240, 241 and beyond them, so that a planar support for the base section 300 is achieved centrally between the engagement projections 240, 241 and also directly in the region of the engagement projections 240, 241.

[0259] In the connected position, the belt 4 is arranged on the connecting piece 3 at approximately the height of the engagement projections 240, 241 on the connecting piece 2 or below the engagement projections 240, 241. This has the effect that the belt force introduced via the belt 4 cannot tilt the connecting piece 3 in the receiving opening 23 or can only generate a small tilting moment, wherein the engagement projections 240, 241 ensure the position of the connecting piece 3 on the connecting piece 2, especially in the height direction H.

[0260] In the connected position and under load between the connecting parts 2 , 3 , the belt 4 is inserted between the raised sections 242 , 243 and thus between the engagement projections 240 , 241 , so that the engagement projections 240 , 241 are supported symmetrically with respect to the belt 4 via the belt 4 under force introduction.

[0261] In the connected position, the magnetic devices 21 , 31 interact magnetically to hold the connecting parts 2 , 3 in the connected position.

[0262] Since the blocking element 303 is engaged in the recess 231, a tangential movement of the connecting parts 2, 3 relative to each other is also blocked against the joining direction Y. The blocking element 303 is inserted into the recess 231 in the connected position, so that the blocking element 303 is accommodated between the limiting walls 236 that realize the blocking section and is in blocking contact with the arc-shaped limiting walls 236, so that the blocking element 303 cannot move relative to the limiting walls 236 against the joining direction Y.

[0263] Due to the rotationally symmetrical shape of the blocking element 303 and the cylindrical shape of the base section 300 , the connecting piece 3 can be moved in the connected position along a circumferential direction U about the rotation axis R (see Figure 2A ) can be twisted at any angle within the receiving opening 23 of the connecting piece 2 while maintaining the connection between the connecting pieces 2 , 3 and also while blocking the blocking element 303 in the recess 231 .

[0264] The twistability also enables the connection elements 2, 3 to be attached to each other in any rotational position, wherein the connection elements 2, 3 are oriented relative to each other via the strap 4 under load, so that the strap 4 is placed between the engagement projections 240, 241 and the connection element 3 is supported symmetrically on the connection element 2. Due to the twistability, the connection elements 2, 3 are attached to each other with position tolerance, which makes the establishment of the connection simple and comfortable.

[0265] As this from Figure 4A-4G As can be seen in the figure, the front edge section 305 of the base section 300 sinks into the sinking opening 232 when sliding under the engagement projections 240, 241, and the sinking opening is formed not only in a recessed manner relative to the bottom surface 230 but also relative to the recess 231. Due to the sinking of the edge section 305 into the sinking opening 232, the blocking element 303 can slide into the recess 231 and establish the engagement of the engagement section 340 formed on the base section 300 with the engagement projections 240, 241. In addition, this can increase the angular range of the opening force applied to the actuating section 40 (tab) and prevent the edge section 305 from being clamped during opening.

[0266] In the connected position, the front edge section 305 of the base section 300 then rests on a positive-fit section in the form of a step 234 formed between the recessed opening 232 and the support section 233 at the level of the bottom surface 230. By the base section 230 resting on the step 234, the connecting part 3 is additionally supported against tilting relative to the connecting part 2.

[0267] Alternatively, the shape-fitting section can also be formed on the support section 233, for example by a recess, into which the base section 300 engages with the edge section 305 and is thus supported on the support section 233 to prevent tilting, which is accompanied by the downward movement of the edge section 305 on the support section 233 along the closing direction X.

[0268] The form-fitting section in the form of a step 234 prevents tilting in the connection position, in particular when a load is applied to the belt 4. Thus, the second connection part 3 with its base body 30 rests in the connection position with a first region formed by the rear region (with respect to the joining direction Y) on the bottom surface 230 of the base body 20 of the first connection part 2. In the second region connected in the joining direction Y, formed by the region above the recessed opening 232, the second base body 30 of the second connection part 3, in contrast, does not rest on the first base body 20 of the first connection part 2. With the aid of a third region connected in the joining direction Y, formed by the front edge section 305 of the base section 300, the second base body 30 rests on the step 234, so that a two-point bearing type support is achieved in the connection position, with a free space formed between them in the region of the recessed opening 232.

[0269] In the load-bearing position, the base section 300 bears the load with the front edge section 305 against the support section 233 and thus holds the step 234 in a self-reinforcing manner.

[0270] If the connectors 2 and 3 are to be separated from each other, the movement process is essentially carried out in the opposite direction. In particular, in order to separate the connectors 2 and 3, the user grips the actuating section in the form of a tab 40 (formed by a protruding section of the belt 4) on the rear side of the connector 3 facing away from the engagement projections 240 and 241, thereby lifting the connector 3 at its rear end from the bottom surface 230 and thus tilting the connector 3 from the connected position relative to the connector 2, so that the base section 300 slides off the step 234 with the front edge section 305 and lifts the blocking element 303 out of the recess 231, as shown in FIG. Figure 5A-5G In this way, the obstruction between the connecting members 2 and 3 in the direction opposite to the joining direction Y is eliminated, so that the connecting member 3 can be disengaged from the joining with the connecting member 2 in the direction opposite to the joining direction Y, so that the connecting members 2 and 3 can be released from each other.

[0271] The tilting takes place in an inclined plane which is oriented perpendicularly to the bottom surface 230 , ie formed by the closing direction X and the joining direction Y. The tilting is approximately about a tilting axis K (see Fig. 5F ) is carried out so that the connecting part 3 performs a pivoting movement in an inclined plane perpendicular to the tilting axis K, thereby lifting the blocking element 303 out of the recess 231, so that the connecting parts 2 and 3 move relative to each other in the opposite direction of the joining direction Y and can be separated from each other.

[0272] If, in particular when the connection device 1 is not under load, the connection of the connection parts 2, 3 is to be released, the connection parts 2, 3 are tilted relative to each other and in particular also moved relative to each other opposite to the joining direction Y, so that the front edge section 305 of the base section 300 (forming the third area) slides off the step 234 and sinks into the area of ​​the sinking opening 232. The form-fitting section established by the step 234 thus no longer (any more) inhibits tilting, so that the connection parts 2, 3 can be easily and easily separated from each other via the actuation section 40 during tilting.

[0273] In the illustrated embodiment, the second connecting member 3 can be attached to the first connecting member 2 in an (arbitrary) twisted position, and in an arbitrary rotational position, the engagement section 340 of the second connecting member 3 can engage with the engagement projections 240, 241 of the first connecting member 2. In the connected position, the second connecting member 3 can be rotated relative to the first connecting member 2 along the circumferential direction U around the rotation axis R while maintaining the engagement of the engagement section 340 with the engagement projections 240, 241 and while engaging the blocking element 303 in the recess 231.

[0274] If, under load, in the connected position of the connection device 1, a belt force acts between the belts 4, 5, the belt 4 is inserted between the engagement projections 240, 241, as this Figure 2A-2G The engagement projections 240, 241 are arranged in the present case laterally on the strip 4, so that the strip 4 extends through between the engagement projections 240, 241 (viewed in a transverse direction Q pointing from the engagement projection 240 to the engagement projection 241).

[0275] In contrast, if the second connecting member 3 is twisted relative to the first connecting member 2 along the circumferential direction U about the rotation axis R, the belt 4 can extend over one of the engagement projections 240, 241, while the belt 4 is flexibly and softly deformed. During twisting, the belt 4 (in relation to the rotation direction) slides on one of the engagement projections 240, 241 and is deformed, so that the belt 4 can move over the corresponding engagement projection 240, 241.

[0276] In the embodiment shown, the second connecting element 3 is connected to an associated component in the form of a belt 4 via a seam 5 and is sewn to the belt 4 .

[0277] If this is based on Figure 1AAs can be seen in the exploded view of FIG, the base body 30 of the connecting piece 3 faces the belt 4 with the fastening section 301 and forms the outer side, and the fastening section 301 and the base body 30 are in contact with the belt 4 with the outer side. The outer side of the fastening section 301 facing the belt 4 extends along a flat plane perpendicular to the closing direction X, along which the belt 4 can be connected to the base body 30 and fastened to the base body 30 in the state of the conventional configuration.

[0278] The sewing holes 50 are formed at the base body 30 and extend through the base body 30. The sewing holes 50 are arranged one after another along a circular line (approximately) at the outer side of the fastening section 101 and constitute a series of sewing holes 50 extending around the fastening opening 35 in which the magnetic device 31 of the connecting piece 3 is accommodated.

[0279] As this from Figure 1B As can be seen in the figure, a groove 51 is formed at the base section 300 on the inner side facing the connecting piece 2, and the suture hole 50 leads into the groove. The groove 51 extends around the blocking element 303 formed centrally at the base body 30, and the fastening opening 35 is formed inside the blocking element, and the magnetic device 31 is accommodated in the fastening opening.

[0280] The groove 51 is shaped as a recess at the base face 302 of the base section 300 of the base body 30 and follows a series of suture holes 50 at the inner side of the base body 30 .

[0281] The stitching 5 is formed by a stitching line, which is guided through the belt 4 and the stitching hole 50, for example, when using a CNC sewing machine, so as to sew the connecting member 3 to the belt 4. Therefore, through the stitching 5, the belt 4 can be sewed to the base 30 of the connecting member 3 via the stitching hole 50 to be firmly connected to the connecting member 3.

[0282] The arrangement of the sewing holes 50 forms a sewing area 52, at which a seam 5 can be established in order to sew the belt 4 to the connecting element 3. Figure 3C and Figure 3E Combination Figure 3B The stitching area 52, as depicted, defined by the series of stitching holes 50, has a spacing A2 from the center Z2 of the magnetic device 31 of the connecting piece 3, which is smaller than the spacing A2' of the surrounding joining section 340 from the center Z2 of the magnetic device 31. Therefore, after the strap 4 is connected to the connecting piece 3, the stitching 5 is closer to the magnetic device 31 than the joining section 340.

[0283] As this from Figure 3EAs can be seen in FIG. 1 , at the (radial) position where the stitching 5 is established, the distance A2 between the center Z2 of the magnetic device 31 and the stitching area 52 is measured along a plane defined by the outer side of the fastening section 301 and perpendicular to the closing direction X. In contrast, the distance A2' is measured between the center Z2 of the magnetic device 31 and the outer edge of the joining section 340. The distance A2 is smaller than the distance A2', so that the stitching area 52 with the stitching 5 arranged thereon is closer to the magnetic device 31 than the joining section 340.

[0284] The seam 5 is thus formed in the base body 30 of the connecting element 3 in a central region around the magnetic device 31. As a result, the seam 5 extends over a relatively small surface area and has little effect on the installation space of the connecting element 3.

[0285] This results in a favorable force flow, in which the force is introduced centrally into the connecting part 3 via the strip 4 and into the connecting part 2 by the engagement of the engagement section 340 with the engagement projections 240 , 241 .

[0286] In the embodiment shown, the connecting element 3 is formed rotationally symmetrically with respect to the base body 30. The magnetic device 31 is arranged in the center of the base body 30 so that the center Z2 of the magnetic device 31 is aligned with the rotation axis R (see Figure 2A )coincide.

[0287] The center Z2 corresponds to the center of gravity of the magnetic device 31 and is projected onto a plane defined by the outer side of the fastening section 301 .

[0288] Fig. 6A , Figure 6B A further embodiment of a connecting element 3 is shown, which can be connected to a further connecting element in order to realize a connecting device.

[0289] According to Figure 1A , Figures 1B to 5A - Figure 5G The embodiments are different, in accordance with Fig. 6A , Figure 6B In the embodiment of the present invention, the base body 30 of the connecting part 3 is not rotationally symmetrically formed, but has a rectangular shape (viewed along a plane defined by an outer side that can be connected to the associated component 4). The base body 30 forms two engagement sections 340, 341 at outer edges facing away from each other, which are undercut so that they can engage with the associated engagement projections 240, 241 of the associated connecting part 2.

[0290] In the embodiment shown, an arrangement of mutually aligned suture holes 50 is formed on the base body 30 on the outer side facing the component 4. The mutual arrangement of the suture holes 50 follows a polygonal line consisting of three straight lines which are connected to each other at an angle of 90° and are bent relative to each other.

[0291] The suture holes 50 are arranged around the central fastening opening 35 in which the magnetic device 31 is received, as in the case of Fig. 6A Visible in.

[0292] Similar to Figure 1A , Figures 1B to 5A - Figure 5G In the embodiment of the present invention, at least some of the suture holes 50 are arranged closer to the central magnetic device 31 than the joining sections 340, 341, and correspondingly have a spacing A2 from the center Z2 of the magnetic device 31, which is smaller than the spacing A2' between the joining sections 340, 341 and the center Z2 of the magnetic device 31, as shown in Fig. 6A Drawn in.

[0293] At the connector 3 Fig. 7A , Figure 7B In another embodiment shown in FIG. 1 , at the outer edges of the base body 30 pointing away from each other (similar to the embodiment according to Fig. 6A , Figure 6B In the embodiment of the invention, a joining section 340, 341 is formed, wherein the connecting piece can be joined with another associated connecting piece of the connecting device.

[0294] An arrangement of stitching holes 50 is formed between the joining sections 340 , 341 , which are arranged one next to the other along the outer side of the component 4 and form a stitching area 52 which is at least partially closer to the magnetic device 31 of the connecting part 3 than the joining sections 340 , 341 .

[0295] The suture holes 50 are arranged along a straight line. The suture part 5 can be placed on the suture holes 50 to sew the component 4 and the connecting member 3 together.

[0296] Fig. 8A , FIG. 8B to FIG. 10A - Fig.10F Shown in use according to Fig. 6A , Figure 6B An embodiment of the connection device 1 with a connection piece 3 which can be connected with an associated connection piece 2 in order to close the connection device 1 . Figure 9A-9F Correspondingly, the connecting device 1 is shown in the connected position of the connecting parts 2 , 3 .

[0297] On the connecting piece 3, at the edges of the base body 30 pointing away from each other and outward, joining sections 340, 341 are formed, which are undercut with respect to the closing direction X in that the sections of the base body 30 respectively connected to the joining sections 340, 341 are recessed, thereby releasing space behind the respective joining sections 340, 341. 9A to 9FAs can be seen in FIG. 2 , the connecting piece 3 can be engaged with the engaging protrusions 240 , 241 on the raised sections 242 , 243 of the base body 20 of the connecting piece 2 via the engaging sections 340 , 341 .

[0298] In the connected position, the connecting parts 2 , 3 are fixed relative to each other in the closing direction X and also in a direction oriented transversely thereto by means of the magnetic devices 21 , 31 and also by the engagement of the engagement sections 340 , 341 with the engagement projections 240 , 241 .

[0299] Taking into account the closing process and also the opening process and the holding in the connected position, according to Fig. 8A , FIG. 8B to FIG. 10A - Fig.10F The embodiment is functionally similar to Figure 1A , Figures 1B to 5A - Figure 5G of the embodiments, so that reference should also be made to the Figure 1A , Figures 1B to 5A - Figure 5G The above implementation scheme of the embodiment of the embodiment.

[0300] According to Figure 1A , Figures 1B to 5A - Figure 5G Unlike the embodiment of the present invention, the connecting member 3 is formed non-rotationally symmetrically with the base body 30 and forms two spatially separated connecting sections 340, 341 instead of a surrounding connecting section. Accordingly, the connecting members 2, 3 cannot be rotated relative to each other in the connected position, but are held fixed relative to each other.

[0301] In the embodiment shown, the connecting element 3 is connected to the belt 4 via a stitching 5. An arrangement of stitching holes 50 extending around the fastening opening 35 is realized on the base body 30, in which the magnetic device 31 is accommodated. In this case, at least some of the stitching holes 50 are closer to the magnetic device 31 than the joining sections 340, 341 at the outer edges of the base body 30, such as Fig. 8A Combination Fig.9A and Fig.9E visible.

[0302] In particular, at least some of the stitching holes 50 have a distance A2 from the center Z2 of the magnetic device 31 that is smaller than a distance A2 ′ of the engagement devices 340 , 341 from the center Z2 of the magnetic device 31 .

[0303] In addition, according to Fig. 8A , FIG. 8B to FIG. 10A - Fig.10FIn the embodiment of the present invention, the connecting element 2 is also sewn to an associated component 7, for example in the form of a planar material section. In this case, the base body 20 of the connecting element 2 has an arrangement of sewing holes 60, which are arranged one after another around the fastening opening 25 on the outer side of the base body 20 of the connecting element 2 facing the component 7 along a plane defined by the outer side, such as from Figure 8B It can be seen that the magnetic device 21 is accommodated in the fastening opening.

[0304] The suture hole 60 extends through the main body 20 and opens into a groove 61 on the inner side of the connecting part 2 facing the connecting part 3 .

[0305] The sewing holes 60 form sewing regions 62 , via which the seams 6 can be produced, so that the component 7 can be sewn to the connecting element 3 .

[0306] Here, at least some of the stitching holes 60 have a spacing A1 relative to the center Z1 of the magnetic device 21 that is smaller than the spacing A1' between the center Z1 of the magnetic device 21 and the engaging protrusions 240, 241, as in Figure 8B As a result, at least some of the suturing holes 60 are closer to the magnetic device 21 than the engaging protrusions 240 , 241 .

[0307] Therefore, according to Fig. 8A , FIG. 8B to FIG. 10A - Fig.10F In the embodiment of the present invention, the two connecting members 2 , 3 are sewn to the associated components 4 , 7 , respectively, wherein the sewing is performed via sewing areas 52 , 62 , respectively, which are arranged in a positional relationship close to the magnetic devices 21 , 31 .

[0308] Figures 11A-11G Show according to Fig. 6A , Figure 6B The connecting member 3 can be connected with the Fig. 8A , FIG. 8B to FIG. 10A - Fig.10F Used together with the connecting piece 2.

[0309] Figure 12A-12G Show according to Fig. 7A , Figure 7B The connection part 3 can be arranged according to Fig. 8A , FIG. 8B to FIG. 10A - Fig.10F The connector is used at 2 locations.

[0310] Figure 13A-13G and Fig.14 Shown in accordance with Fig. 8A , FIG. 8B to FIG. 10A - Fig.10FStructurally, the connector 2 is similar to the connector according to the embodiment of the present invention. Fig. 8A , FIG. 8B to FIG. 10A - Fig.10F However, according to Figure 13A-13G and Fig.14 Embodiments and basis Fig. 8A , FIG. 8B to FIG. 10A - Fig.10F The difference of the embodiment of the present invention is that no continuous suture area is created at the base body 20, but the suture holes 60, 60' are arranged along two straight lines extending parallel to each other, as shown in FIG. Fig.14 Thus, two stitching areas 62, 62' are created on the connecting element 2 for accommodating each stitching 6, 6'.

[0311] The suture holes 60 , 60 ′ each open into an associated groove 61 , 61 ′ on the inner side of the connecting part 2 facing the other connecting part 3 .

[0312] For each of the stitching areas 62, 62', at least some of the stitching holes 60, 60' are closer to the magnetic device 21 in the center of the connector 2 than the engaging protrusions 240, 241, and correspondingly have a spacing A1, A1'' from the center Z1 of the magnetic device 21, which spacing is smaller than the spacing A1' of the engaging protrusions 240, 241 from the center Z1 of the magnetic device 21, as shown in Fig.13D and Fig.13F Drawn in.

[0313] Fig.15A , FIG. 15B to FIG. 17A - Fig.17H A further embodiment of a connection device 1 is shown, in which the connection elements 2, 3 can be attached to each other along a closing direction X. Figures 16A-16H In the connection position shown in , the connection parts 2 , 3 are connected to one another.

[0314] The connecting parts 2 , 3 each have a base body 20 , 30 , on which magnetic devices 21 , 31 are arranged. The magnetic devices 21 , 31 act together magnetically in a closing direction X, thereby attracting the connecting parts 2 , 3 towards each other, in order to assist the attachment.

[0315] In the embodiment shown, an engagement section 340 is formed on the base body 30 of the connection piece 3, which engagement section protrudes radially outward, surrounds the pin-shaped base body 30, and is undercut with respect to the closing direction X. Correspondingly, a section which is recessed radially inward relative to the engagement section 340 is connected to the engagement section 340, so that the engagement section 340 can engage with an associated engagement projection 240 on the side of the connection piece 2, such as this from Figure 16G Visible in.

[0316] In the exemplary embodiment shown, an elastically resilient spring locking element 246 is provided on the base body 20 of the connecting element 2 , said spring locking element carrying the engagement projection 240 .

[0317] The spring locking element 246 has the shape of a C-ring which can be elastically widened in a plane perpendicular to the closing direction X so that the engagement section 340 on the base body 30 of the connecting piece 3 can engage in the closing direction X with the spring locking element 246 .

[0318] The spring locking element 246 constitutes the engagement device 24 in that an engagement protrusion 240 is formed on the spring locking element 246, which protrudes radially inward and can engage with the engagement section 340 of the connecting piece 3. Here, an engagement protrusion 240 is formed on each leg of the spring locking element 240 formed by a C-shaped ring. Another third engagement protrusion 240 is formed at the middle distance between the two legs.

[0319] In order to close the connection device 1, the connection pieces 2, 3 are attached to each other along the closing direction X, so that the connection piece 3 engages with the spring locking element 246 of the connection piece 2 with the engagement section 340. The spring locking element 246 widens radially during insertion until the engagement section 340 has passed the engagement projection 240 and the spring locking element 246 engages with the engagement projection 240 with the engagement section 340.

[0320] The attachment is effected by magnetic attraction of the magnetic means 21 , 31 , so that the connecting parts 2 , 3 are attracted towards each other and the engagement section 340 preferably autonomously engages with the spring locking element 246 when the connecting parts 2 , 3 are brought close together.

[0321] In accordance with Figures 16A-16H In the connection position, the spring locking element 246 surrounds the base body 30 of the connection piece 3. By the engagement of the engagement section 340 with the engagement projection 240, the connection pieces 2, 3 are fixed relative to each other along the closing direction X.

[0322] In order to open the connection device 1, the connection piece 3 can be moved relative to the connection piece 3 in the opening direction O so as to move the engagement section 340 in the opening direction O in the manner described in order to disengage the spring locking element 246. As a result, the connection piece 3 is moved out of the spring locking element 246 through the lateral opening of the C-shaped ring, so that the engagement section 340 is disengaged from the engagement protrusion 240 at the spring locking element 246, so that the connection pieces 2, 3 are separated from each other.

[0323] In the embodiment shown, the connecting element 3 is connected to the associated component 4 in the form of a belt by means of stitching 5. In this case, stitching holes 50 are provided on the base body 30 for forming an access region 52, which are arranged one above the other around the closing direction X.

[0324] A series of sewing holes 50 extends around the fastening opening 35 in which the magnetic device 31 is accommodated in the base body 30 .

[0325] As this Figure 16G It is shown that the stitching hole 50 is closer to the magnetic device 31 than the joining section 340 by setting the stitching hole 50 at a radial distance A2 from the center Z2 of the magnetic device 31, which is smaller than the radial distance A2' of the joining section 340 from the center Z2 of the magnetic device 31.

[0326] In the illustrated embodiment, the connecting element 2 is connected to the associated component 7 via a threaded ring 27 screwed onto the threaded section 200. In one embodiment, the connecting element 2 can also be sewn to the associated component 7.

[0327] In accordance with Figure 1A , Figures 1B to 5A - Figure 5G In the embodiment of the present invention, the base body 30 of the connecting member 3 is at least approximately rotationally symmetrically shaped. However, this is not mandatory. In particular, the joining section 340 of the connecting member 3 can also be shaped non-rotationally symmetrically.

[0328] Therefore, in Figure 19A-19E In the embodiment shown in , the joining section 340 is not formed circumferentially on the base section 300 of the connecting piece 3. The undercut joining section 340 is formed especially in the region of the end side pointing along the joining direction Y, but not on the rear section pointing opposite to the joining direction Y.

[0329] The connecting element 3 is in turn sewn to the associated component 4 , wherein the sewing region 52 is closer to the central magnetic device 31 than the end-side joining section 340 .

[0330] according to FIG. 19A to FIG. 19E The connector can be connected with Figure 1A , Figures 1B to 5A - Figure 5G The connecting piece 2 is engaged.

[0331] exist Fig. 20A , Fig. 20B and Figure 21A-Figure 21EIn another embodiment shown in FIG. 1 , the base body 30 of the connecting element 3 is polygonally shaped and follows the polygonal lines of a hexagon at the surrounding outer contour. The connecting element 3 is in turn sewn to the associated component 4 via a sewing portion 5, wherein the sewing area 52 is closer to the central magnetic device 31 than the joining section 340 formed by the polygonal outer contour, in that the sewing area 52 has a distance A2 from the center Z2 of the magnetic device 31, which is smaller than the distance A2' between the center Z2 and the outer joining section 340, as shown in FIG. Fig.21B Drawn in.

[0332] according to Fig. 20A , Fig. 20B , Figure 21A-Figure 21E The connecting piece 3 can be connected with Figure 1A , Figures 1B to 5A - Figure 5G Similar connecting elements are commonly used to realize the connecting device 1 .

[0333] Figure 22A-22C A further exemplary embodiment of a connecting device 1 having connecting elements 2 , 3 is shown in section.

[0334] according to Figure 22A-22C The connection device 1 corresponds in function to a large extent to the Figure 1A , Figures 1B to 5A - Figure 5G Embodiment of the invention. Figure 1A , Figures 1B to 5A - Figure 5G The embodiments are different, in accordance with Figure 22A-22C In the embodiment, a locking element 26 is additionally provided on the first connecting member 2, which forms a coupling protrusion 260, which is designed to cooperate in a form-fitting manner with a coupling section 340 formed circumferentially on the base section 300 of the second connecting member 3 in the connected position of the connecting members 2 and 3.

[0335] The locking element 26 is arranged on the base 20 of the first locking part 2 in a manner that it can move along a locking direction V oriented transversely to the closing direction X, so that the locking element 26 can move along the locking direction V relative to the base 20 so as to engage or disengage the engaging protrusion 260 with the engaging section 340 at the base 300 of the base 30 of the first connecting part 3.

[0336] In the embodiment shown, a third magnetic device 261 is provided on the locking element 26, which is designed to magnetically cooperate with the second magnetic device 31 of the second connecting part 3. If the connecting parts 2, 3 are attached to each other along the closing direction X, the magnetic devices 261, 31 magnetically attract each other, so that the locking element 26 is loaded in the direction in which the engagement projection 260 engages with the engagement section 340.

[0337] When the connectors 2 and 3 are attached to each other, the base 300 collides with the collision slope formed thereon onto the collision slope at the engagement projection 260, so that the locking element 26 is first pressed to one side against the locking direction V when the connectors 2 and 3 are attached, as shown in FIG. Fig. 22B If the second connecting member 3 has passed the engaging protrusion 260 with the base 30, due to the magnetic attraction between the magnetic devices 261 and 31, the locking element 26 engages with the engaging section 340 at the base 300 along the locking direction V with the engaging protrusion 260 provided thereon, as shown in FIG. Fig. 22C Visible in.

[0338] If the connecting device 1 is to be opened, the user can adjust the locking element 26 via the actuating tab 262 counter to the locking direction V in order to cancel the engagement of the engagement projection 260 with the engagement section 340 in the described manner so that the connecting parts 2 , 3 can be separated from each other.

[0339] In accordance with Figure 22A-22C In an embodiment of the present invention, it can be provided that the third magnetic device 261 of the locking element 26 and the first magnetic device 21 of the first connecting member 2 act together in a magnetically repelling manner, so that when the connecting device 1 is opened, the locking element 26 remains in an unlocked position pulled back against the locking direction V. This can make it easier to attach the connecting members 2 and 3 to each other. When the connecting members 2 and 3 are attached to each other, from a certain point on, the magnetic attraction between the third magnetic device 261 and the second magnetic device 31 exceeds the magnetic repulsion between the third magnetic device 261 and the first magnetic device 21. Therefore, if the connecting members 2 and 3 are already attached to each other, due to the magnetic attraction, the locking element 26 engages with the engagement section 340, so that the connecting members 2 and 3 are locked relative to each other.

[0340] In addition to the locking element 26, Figure 22A-22C The embodiments are functionally similar to those according to Figure 1A , Figures 1B to 5A - Figure 5G The same embodiment as that of Figure 1A , Figures 1B to 5A - Figure 5G In particular, according to Figure 22A-22CIn the embodiment of FIG. 4 , the second connecting element 3 is also connected to the associated component 4 in the form of a belt via a stitching 5 .

[0341] exist Figure 23A-23D In another embodiment shown in FIG. 1 , the connecting device 1 has two connecting elements 2 , 3 which can be attached to one another along a closing direction X. The first connecting element 2 has a first base body 20 which forms a receiving opening 23 into which the second connecting element 3 can be inserted with a second base body 30 along the closing direction X in order to connect the connecting elements 2 , 3 to one another.

[0342] Each connecting element 2 , 3 has magnetic means 21 , 31 which act together magnetically so as to magnetically assist the connecting elements 2 , 3 to attach to each other.

[0343] Similar to the above description, according to Figure 23A-23D In the embodiment of the second connecting element 3, the second connecting element 3 is firmly connected to the associated component in the form of a belt 4 via a stitching 5. For this purpose, stitching holes 50 are formed on the second base body 30, through which the stitching line extends. The stitching holes 50 are arranged one after another on the first base body 50 and form a series of stitching holes 50, which extend around the magnetic device 31 of the connecting element 3, similar to the above according to Figure 1A , Figures 1B to 5A - Figure 5G The embodiments described herein.

[0344] A locking element 26 is provided on the connection piece 2, which is guided movably on the base body 20 along a locking direction V pointing transversely to the closing direction X and carries an engagement projection 260. In addition, the locking element 26 has a third magnetic device 261, which cooperates magnetically with the magnetic device 31 of the connection piece 3 when the connection pieces 2, 3 are attached to each other.

[0345] The connecting device 1 is closed by the connecting parts 2, 3 being brought closer together along the closing direction X and the connecting part 3 with the base body 30 being inserted into the receiving opening 23 of the base body 20 of the connecting part 2, as is done in the example of the embodiment of the invention. Fig.23A towards Fig.23D This is done in a magnetically assisted manner by the magnetic attraction of the magnetic devices 21 , 31 of the connecting parts 2 , 3 .

[0346] When the connecting parts 2, 3 are attached to each other, the connecting part 3 passes the engaging protrusion 260 of the locking element 26 with the engaging section 340 formed thereon, as shown in FIG. Fig. 23B and Fig.23CIf the engagement section 340 has passed the engagement protrusion 260 , the locking element 26 autonomously engages with the engagement section 340 via the engagement protrusion 260 due to the magnetic attraction between the magnetic devices 261 , 31 .

[0347] To open the connecting device 1 , the locking element 26 can be moved on the base body 20 counter to the locking direction V, for example by actuation by a user, so that the engagement between the engagement projection 260 and the engagement section 340 is released and the connecting parts 2 , 3 can be removed from each other.

[0348] In accordance with Figure 23A-23D In the embodiment of the invention, the magnetic device 261 of the locking element 26 and the magnetic device 21 of the first connecting member 2 can also be arranged opposite to each other in a magnetically repelling manner. When the connecting device 1 is opened, in the described case, the locking element 26 remains on the base body 20 in an unlocked position retracted against the locking direction V, which can facilitate the attachment of the connecting members 2 and 3. When the connecting members 2 and 3 are attached to each other, from a certain point on, the magnetic attraction between the third magnetic device 261 and the second magnetic device 31 exceeds the magnetic repulsion between the third magnetic device 261 and the first magnetic device 21. Therefore, if the connecting members 2 and 3 are already attached to each other, due to the magnetic attraction, the locking element 26 engages with the engagement section 340, so that the connecting members 2 and 3 are locked relative to each other.

[0349] A connecting device 1 of the type described can be used, for example, at a bag or backpack. The connecting device 1 can be used to connect strap ends, to connect a strap to a bag body or to close a bag or backpack lid or to place an object on a bag or backpack.

[0360] The connecting device 1 can be used as a holding device for a camera, for example for connecting a camera to a belt.

[0361] The connecting device 1 can be used as a closure for a watch or a watch strap.

[0362] In all the applications mentioned, the rotatability of the connection elements 2, 3 solves an important aspect of the requirements of the respective application. Conventional plug-in closures, which are often used for applications of this type, are not rotatable.

[0363] Other application possibilities are conceivable and feasible.
