Description

Technical Field

[0001] The proposed solution relates to a connecting device according to the preamble of claim 1 .

[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 having at least one engagement projection. The connection device also comprises a second connection piece associated with a second component and insertable at the first connection piece, the second connection piece having a second base body having at least one engagement section 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 connecting device is configured as a magnetic connecting device. For this purpose, the first connecting part has a first magnetic device and the second connecting part has a second magnetic device. The first magnetic device and the second magnetic device act together magnetically to support the first connecting part and the second connecting part to be placed on each other. Background Art

[0004] In the known locking device for releasably connecting two parts from EP 3 616 553 A1, a first connecting member can be placed on a second connecting member so that the connecting members are connected to each other. Here, a lace is provided at one of the connecting members, which lace can be tensioned by connecting the connecting members to each other.

[0005] A buckle 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 placing the connecting elements on each other, the components can be connected to each other. One or both of the components can be formed, for example, by material sections, for example of textile material, leather material or also of 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. Summary of the invention

[0007] The proposed solution is based on the object of providing a connecting device which enables a simple to produce and reliable connection of components to one another.

[0008] This object is achieved by a connecting device having the features of claim 1 .

[0009] Here, the proposed connection device comprises in particular: a first connection part associated with the first component, the first connection part having a first base body and a coupling device, the coupling device having at least one coupling protrusion; and a second connection part associated with the second component, which can be placed on the first connection part, the second connection part having a second base body, the second base body having at least one coupling section arranged on the second base body. At least one coupling section can be engaged with the coupling device of the first connection part, so that in the connection position (of the first and second connection parts), the first connection part and the second connection part are held on each other. The first connection part and the second connection part each have a magnetic device, which acts together magnetically to support the first connection part and the second connection part to be placed on each other. In order to be able to manually or mechanically place the second connection part on the first connection part and release it from the second connection part in the connection position, the second connection part is connected to an operating section. The second connection part can be placed on the first connection part via the operating section. In addition, in the connection position of the first and second connection parts, an (opening) force can be introduced at the operating section in order to disengage the coupling section from the coupling device and release the second connection part from the first connection part.

[0010] In the connection devices known on the market, the operating section is typically connected to a base section or transitions into such a base section, at which the second base body of the second connection element is arranged. Therefore, displacement of the operating section is accompanied by direct displacement of the second base body, wherein the connection to the second component is typically also established via the base section or the base section is part of the second component. Therefore, the operating section is designed to place the second connection element on the first connection element and thereby introduce a force in the connected position of the first and second connection elements in order to disengage the engagement section from the engagement device.

[0011] Thus, for example, by pulling at the operating section, the second connecting element can be brought close to the first base body of the first connecting element by means of the second base body and the section of the second component connected to the second base body, and the two connecting elements can be joined to each other in order to connect the two components to each other via the connecting device. For example, a tensile force is introduced via the operating section in order to bring close to the belt of the second component carrying the second connecting element, the tab or cover carrying the second connecting element or a section similar to the first connecting element and fix it thereon. If a relatively large tensile force must be applied here, for example because the container or clothing whose two components are to be held together is strongly filled or widened so that the second connecting element must be placed on the first connecting element against the tension, then the joining of the joining section at the joining device becomes difficult. In this case, due to the load acting on the connecting device, the loosening of the second connecting element from the first connecting element will also become difficult, especially when the tension that resists the loosening of the connection not only acts directly on the operating section but also on the second base body of the second connecting element. Furthermore, in the connected position of the first and second connecting elements, when the second base body is arranged on the base section connected to the second component, the load acting on the base section via the second component directly acts on the second base body and thus on the connection of the first and second connecting elements.

[0012] In this context, in order to transmit force to the second connecting member so as to disengage the engagement section from the engagement device and to release the second connecting member from the first connecting member, a transmission member is provided at the connecting device, the transmission member comprising an operating section, a base section connected to the operating section and extending along the extension direction, and a bridging section connected to the base section at a first end point. The bridging section extends between the first end point and a second end point spaced apart from the first end point in the extension direction by a length greater than the spacing between the two end points relative to each other. A second base body is held on the bridging section, wherein when the second connecting member is placed on the first connecting member, the bridging section can then be displaced relative to the base section and the operating section by means of the second base body.

[0013] By means of the displaceability of the bridging section and of the second base body arranged thereon, it is possible, for example, to make it easier for at least one engagement section of the second base body to engage with an engagement device of the first base body under magnetic support, since a displacement movement of the second base body relative to the base section and the operating section is permitted for this purpose. Thus, even under stresses acting on the operating section and the base section, the displaceability of the second base body is permitted in a targeted manner, so that the second base body can be snapped onto the first base body, for example, under magnetic support.

[0014] In the connected state of the first and second connecting elements, a force can be introduced again via the actuating section in order to disengage the coupling section from the coupling device and to release the second connecting element from the first connecting element. For example, the force introduced at the actuating section can be transferred via the base section into the bridging section and thereby in turn to the second base body.

[0015] In one embodiment, a defined gap of the second base body relative to the operating section is preset via the bridging section. Therefore, the second base body is provided with the ability to be displaced relative to the operating section by a preset amount. Here, when the second connecting member is placed on the first connecting member, the second base body can be displaced independently of the operating section and relative to the operating section within the limits defined by the bridging section. In addition, in the connection position of the first and second connecting members, in the case of a load acting on the base section (for example, from the second component to the base section), the base section can be displaced toward the second base body via the bridging section. Thus, in the connection position, not every load acting on the second component and the base section connected to the second component is directly transferred to the second base body. Therefore, in the connection position, the decoupling of the base section and the second base body is achieved to a certain extent via the bridging section.

[0016] The twistability of the second base body relative to the operating section can also be limited via the bridging section. If the second base body is arranged at a bridging section extending between two end points and displaceable, the twistability of the second base body relative to the operating section can be limited relatively simply, for example, in the length of the bridging section and / or its rigidity.

[0017] In principle, the length bridged by the bridge section between the first end point and the second end point is shorter than the total length of the bridge section between the first end point and the second end point. Here, the second end point can also be arranged at the base section, so that the bridge section extends between two areas of the base section. However, this is by no means mandatory. Thus, for example, the second end point can also be arranged at a component of the second component that is connected to the base section.

[0018] In principle, the tensile force introduced at the operating section and acting in the pulling direction can be transmitted via the base section in order to place the second connecting member on the first connecting member. Here, the bridging section can be displaced relative to the base section along a connecting direction that is inclined relative to the pulling direction and in particular extends vertically, so that the engaging section engages with the engaging device. Therefore, a relatively large tensile force can be applied (in particular manually) along the pulling direction in order to bring the first and second connecting members sufficiently close to each other so that the engaging section engages with the engaging device supported by the magnetic interaction of the first and second magnetic devices and the first and second connecting members can be transferred into the connecting position. By displacing the second base body relative to the base section loaded with tensile force by means of the bridging section, the second base body can approach the first base body up to a preset minimum distance in order to achieve the engagement and thus the second base body is snapped into the first base body without the corresponding tensile force acting on the second base body itself.

[0019] The bridge section is made of a soft material or is elastically displaceable, for example. Producing the bridge section from a soft material includes, for example, that the bridge section is made of a soft material section, for example, a soft, in particular textile material section, a leather material section or a plastic surface section.

[0020] In one embodiment, the bridge section can be formed in a multi-jointed manner from a solid and / or flexible element. The bridge sections can be displaced relative to one another by adjusting the solid and / or flexible element. For example, in this regard it can be provided that the bridge section comprises a multi-jointed chain, in particular is formed by a multi-jointed chain.

[0021] The second base body can be fixed on the bridging section. This includes, in particular, sewing the second base body to the soft material of the bridging section.

[0022] In an alternative embodiment, the second base body comprises a connecting section, which is at least partially surrounded by a bridging section made of a soft material and / or constructed in a multi-section manner, in particular engaged from the rear. In this case, the second base body is therefore not directly rigidly fixed to the bridging section. More precisely, by partially surrounding the bridging section, the second base body is held on the bridging section and can thereby be displaced relative to the actuating section. By partially surrounding the second base body by a soft and / or multi-section bridging section, it is still possible for the bridging section to transmit a force to the second base body at the connecting section in order to disengage the engaging section from the engaging device and to displace the second base body relative to the first base body for this purpose.

[0023] In principle, it can be provided that in the connection position of the first and second connecting elements, the second base body can be tilted relative to the first base body in order to disengage the engagement section from the engagement device. Therefore, the first and second connecting elements are configured here so that the second base body must perform a pivoting movement relative to the first base body in order to disengage the engagement section from the engagement device. In particular, a transmission element with a bridging section is provided correspondingly to this in order to transmit the force that causes the pivoting movement of the second base body relative to the first base body to the second connecting element in the connection position. Therefore, the second base body can be tilted relative to the first base body in order to achieve disengagement of at least one engagement section and at least one engagement projection in order to separate the first connecting element and the second connecting element from each other. In this regard, it can be provided, for example, that in order to tilt relative to the first base body, the second base body can be lifted from the first base body at the side (of the second base body) facing away from the at least one engagement projection.

[0024] Conversely, for assuming the connection position and for engaging the engagement section with the engagement device, a tilting movement of the second main body relative to the base section and the actuating section can be permitted via the bridging section when the second connecting element is attached to the first connecting element.

[0025] In a possible embodiment, the first connecting element can additionally have a latching 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 latch the engagement of at least one engagement section with at least one engagement projection counter to the engagement direction. When the connecting element is placed, 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. In this case, in the connection position, 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 by the latching section of the first connecting element rigidly formed on the first base body of the first connecting element, in that the latching section cooperates with the associated section of the second connecting element in a latching manner counter to the engagement direction, so that at least one engagement section cannot move counter to the engagement direction towards the at least one engagement projection at least without releasing the latch. Thus, due to the latching effect of the latching section, the engagement of the at least one engagement section with the at least one engagement projection is blocked.

[0026] In the embodiment with the latching section, the connecting parts can be held relative to each other in the connected position due to the magnetic effect of the magnetic device, so that the connecting parts are latched relative to each other by the latching section of the first connecting part against the joining direction. Therefore, the connecting parts cannot be released from each other by a (pure) displacement movement against the joining direction.

[0027] In a possible design, as explained above, in order to release the connecting parts from each other, the second connecting part can be tilted relative to the first connecting part. In a variant with a locking section, in order to release the connecting parts from each other, the second connecting part can be tilted relative to the first connecting part so that the second connecting part moves relative to the first connecting part in an inclined plane developed by the closing direction and the engagement direction, so that the second connecting part can move toward the locking section on the first base body against the engagement direction. By tilting the second connecting part relative to the first connecting part, the locking effect of the locking section can be canceled, so that the second connecting part moves beyond the locking section, so that at least one engagement section of the second connecting part can be disengaged from at least one engagement protrusion of the first connecting part.

[0028] The latching effect of the latching section rigidly arranged on the first base of the first connecting element can achieve that the second connecting element cannot be moved linearly against the joining direction, but tilts in an inclined plane extending through the closing direction and the joining direction to separate the connecting elements from each other. In this case, the tilting movement can be carried out about a defined tilting axis. However, the tilting movement can also be carried out along a curved movement track located in the inclined plane, wherein the second connecting element tilts relative to the first connecting element due to the tilting movement. In this case, the tilting movement can be superimposed by a linear movement against the joining direction and / or against the closing direction.

[0029] It should be noted that the connecting elements can be tilted relative to each other in order to separate the connecting elements. The establishment of the connection between the connecting elements is also not carried out in a linear closing movement, for example, but rather by the connecting elements being placed on each other in a swiveling manner relative to each other in a tilted state and moving in engagement with each other. When establishing the connection, the second connecting element can also be tilted towards the first connecting element in order to achieve an engagement of at least one engagement section of the second connecting element with at least one engagement projection of the first connecting element.

[0030] In a possible design, in the connected position, the second connecting part can be twisted about the closing direction toward the first connecting part. This allows, on the one hand, the connecting parts to be arranged on each other with angular tolerance. In addition, it is possible that the second connecting part is 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, during the twisting, the engagement latching by the latching section also remains. 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 separate from each other.

[0031] The rotatability between the connecting parts in the connected position enables any rotational movement at any angle. However, it is also conceivable that the movement of the connecting parts is limited to a predetermined rotational angle, for example by a stop or the like. Here, the rotational angle is preferably greater than 10°, further preferably greater than 20°, particularly preferably greater than 45°, or even greater than 90°.

[0032] Although not mandatory, at least one engagement projection can be arranged rigidly and non-deformably (under normal loads) on the first base body of the first connecting element. If at least one engagement projection is formed rigidly and non-deformably (under normal loads) on the first base body of the first connecting element, the engagement projection can in some cases absorb and dissipate forces more reliably when engaging with at least one engagement section of the second base body. In this case, the at least one engagement projection can be 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.

[0033] Alternatively or in addition, the joining section can be rigidly arranged on the second base body. This includes, in particular, that the joining section is rigidly formed on the second base body. For example, the second base body of the second connecting element together with at least one joining section formed thereon is rigid and non-deformable and, for this purpose, is composed, for example, of metal or hard plastic material.

[0034] In this context, “non-deformable” is to be understood as a substantially non-yielding geometry and material selection of the base body, which results in the base body of the first connecting part together with the engagement projection formed thereon not being deformed under normal loads, i.e. the base body is not designed to be elastic. For example, the base body of the first connecting part can be made of metal or a hard plastic material.

[0035] In one embodiment, as explained above, the second connecting part can be lifted from the first connecting part on the side facing away from the at least one engagement projection in the opposite direction to the closing direction in order to tilt relative to the first connecting part. Here, the second connecting part can also be engaged with the at least one engagement projection on the first base body of the first connecting part via at least one engagement section arranged on the second base body in the connected position, wherein the engagement takes place in the front area of ​​the second connecting part - viewed with respect to the engagement direction. With the help of the area behind with respect to the engagement direction, the second connecting part can be lifted from the first connecting part in the connected position in the opposite direction to the closing direction in order to tilt the second connecting part relative to the first connecting part in the described manner. If a latching section is provided, the second connecting part can be lifted from the first connecting part in the connected position in the opposite direction to the closing direction in order to tilt the second connecting part relative to the first connecting part in the described manner, thereby canceling the latching effect of the latching section of the first connecting part, so that the second connecting part can move toward the latching section of the first connecting part, and at least one engagement section can be disengaged from the at least one engagement projection in the opposite direction to the engagement direction.

[0036] For example, at least one engagement section of the second connection element is formed by an edge section, which can engage with at least one engagement projection. Alternatively or in addition, at least one engagement section of the second connection element can be circumferentially encircling the first base body. In this case, the second connection element can in particular have a single engagement section, which extends circumferentially on the second base body and here (radially) protrudes outwards. The engagement section is undercut in that another section connected to the engagement section is recessed inwardly relative to the engagement section, thereby achieving engagement of the engagement section with at least one engagement projection of the engagement device of the first connection element.

[0037] If the second base body of the second connecting element is designed rotationally symmetrically with respect to the pin forming the joining section, the joining section projects radially outwards and surrounds the pin in a circular manner.

[0038] However, the second base body can also be designed to be rotationally non-symmetrical. In this case, the joining section can, for example, be angularly, for example quadrilaterally, surrounding the base body.

[0039] The first component and / or the second component can be formed, for example, by a soft material section, for example made of textile material, leather material, plastic surface section or 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 a completely different component. Such a material section can have completely different material thicknesses, wherein in the case of a greater material thickness or in the case of a harder material, the material can be perforated for the placement of the connection device.

[0040] However, the first component and / or the second component can also be formed by a solid object, for example by a plastic component.

[0041] In the connection device, one or both of the connection elements can be connected to the respectively associated component, for example, via a sewed connection, but other types of connections between the component and the associated connection element are also possible. To produce the sewed connection, the sewing thread can be guided through the vicinity of the respective base body in order to produce the sew between the respective connection element and the associated component in the described manner and thus connect the connection element to the component.

[0042] The connecting parts can be placed on each other for connecting the components and are arranged relative to each other in the connected position so that the connecting parts 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 connecting part with the engagement device of the first connecting part. In the operating state, the connecting parts are connected to the respectively associated components. In order to close the connecting device, the connecting parts are placed on each other with magnetic support by the magnetic attraction force of the magnetic device, so that at least one engagement section of the second connecting part engages with at least one engagement protrusion of the engagement device of the first connecting part, thereby establishing a connection between the connecting parts.

[0043] In order to close the connection device, the connection parts can be placed on each other, for example, in a closing direction. The magnetic devices act together magnetically in the closing direction, so that the connection parts are attracted to each other with magnetic support. However, it is also possible to place the connection parts in a direction different from the closing direction.

[0044] In the connected position, the connection between the connecting parts can be play-free or have play.

[0045] 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. In particular, the at least one engagement section and / or the at least one engagement projection can have surfaces extending perpendicularly to the closing direction or surfaces extending obliquely with respect to the closing direction, which surfaces in the connection position point toward each other and establish a form-fitting or force-fitting, play-free or play-containing connection.

[0046] Holding the connecting element in the connected position can act in the closing direction and / or in a direction oriented transversely or obliquely with respect to the closing direction.

[0047] For example, the load direction, along which the belt force acts, can be oriented transversely or obliquely relative to the closing direction. However, the load direction can also act, for example, counter to the closing direction.

[0048] The connection parts are supported magnetically when placed on each other. For this purpose, the first connection part has a first magnetic device and the second connection part has a second magnetic device. The first magnetic device and the second magnetic device in particular support the connection parts to be placed on each other. The magnetic devices act, for example, magnetically attracting in the closing direction, so that the magnetic devices generate a magnetic attraction force in the closing direction and attract the connection parts towards each other in the closing direction when placed.

[0049] The magnetic devices can each be formed, for example, by a permanent magnet. 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.

[0050] In one embodiment, at least one engagement section is formed by an edge section that can engage with at least one engagement projection. At least one engagement section can be formed by an edge section that is circumferentially formed on the second base body and points outwards. In another embodiment, at least one engagement section can not be circumferentially formed on the base body, but can be formed only on the end side, for example. In this case, the edge section can delimit the second base body outwardly when viewed along the second plane.

[0051] Since at least one engagement section can engage with at least one engagement projection parallel to the second plane or along a direction extending obliquely relative to the second plane, wherein the engagement section extends along the second plane on the base body, and when viewed in a direction perpendicular to the second plane, the at least one engagement section and the at least one engagement projection at least partially overlap with each other, a hold is (also) established between the connecting elements in a direction perpendicular to the second plane via the engagement.

[0052] In one embodiment, when viewed along the second plane, at least one engagement section of the second connecting element 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 connecting elements can be arranged on one another to close the connection device (wherein it is not excluded that the connecting elements can also be arranged on one another in a direction different from the closing direction). At least one engagement section of the second base body of the second connecting element protrudes from another section transversely to the closing direction. 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 enabling engagement with at least one engagement projection of the engagement device of the first connecting element.

[0053] On the one hand, the surface of the joining section and on the other hand the surface of at least one joining protrusion can be oriented along a second plane of the joining section or inclined relative to the second plane in order to establish a form-fitting or force-fitting connection, wherein the surfaces face each other in the connected position and engage with each other without gap or with gap, along which second plane the joining section extends on the base body.

[0054] In this case, the connection can be established solely via the at least one engagement section and the at least one engagement projection. However, it is also conceivable that further connection partners cooperate to establish the connection.

[0055] In one embodiment, the second base body has two engagement sections formed at edges that are spaced apart 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 sections protrude 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 connecting device.

[0056] In one embodiment, at least one engagement projection of the first connecting element is rigidly formed on the first base body. Here, at least one engagement section of the second connecting element engages with at least one engagement projection of the first connecting element, for example, along an engagement direction pointing parallel or obliquely relative to a first plane, wherein at least one engagement projection extends along the first plane. Thus, at least one engagement projection of the first connecting element is rigidly and non-elasticly formed on the first base body of the first connecting element.

[0057] 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 by engaging at least one engagement section with at least one engagement projection in an engagement direction pointing parallel or obliquely with respect to the first plane. Thus, in the connected 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 or oblique to the first plane. The surfaces of at least one engagement section and at least one engagement projection facing each other can here be oriented along the first plane or also obliquely with respect to the first plane.

[0058] Therefore, in one design, in the connecting device, one or more engaging protrusions are rigidly formed at the first base of the first connecting member. The second connecting member can engage with the at least one engaging protrusion by engaging at least one engaging section of the second connecting member with the at least one engaging protrusion of the first connecting member. Here, the first connecting member and the second connecting member are arranged on each other, 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 protrusion of the first connecting member is carried out along an engaging direction oriented transversely or obliquely with respect to the closing direction. In the connected position, at least one engaging section is engaged with at least one engaging protrusion in a form-fitting or force-fitting manner, so that the connecting members are held on each other.

[0059] 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.

[0060] At least one joining section can have a curved (arc-shaped) shape. At least one joining section can be formed here in a circumferential manner on the second base body, or alternatively can 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 circumferential on the second base body, the joining section can be formed in a circular circumferential manner or can also have another shape, for example an angular shape, for example a polygonal shape, for example a quadrilateral or hexagonal shape.

[0061] Independently of the specific design of the first and second connecting elements, in particular the specific design of the at least one engaging projection of the engaging device of the first connecting element and 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 toward 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.

[0062] Other designs of the connecting parts are also conceivable and feasible, in which at least one engagement protrusion can be arranged rigidly and movably toward the first base body of the first connecting part, and / or in which at least one engagement section can be arranged rigidly and movably toward the second base body of the second connecting part.

[0063] In principle, the first connecting member and / or the second connecting member can be formed in multiple parts. This includes in particular that the first connecting member and / or the second connecting member comprises at least two elements which are connected in an articulated manner to each other.

[0064] The proposed solution also relates to a system having a first component and a second component, wherein the first and second components can be combined with an embodiment variant of the proposed connection device. In this case, the components can again be part of a superordinate component or be connected to one another via further elements in the overall system. In the proposed system, the base section of the transmission element connected to the actuating section can be connected to the second component or at least partially or completely formed by a section of the second component.

[0065] The embodiment variant of the proposed connecting device can be, for example, a bag or a backpack or a protective garment, for example a part of a protective vest. In the context, for example, the first assembly can be formed by a bag body or a backpack body, and the second assembly can be formed by a bag cover or a backpack cover.

[0066] The following list of possible applications is intended to illustrate the versatility of the connection device, but is not to be understood as restrictive and in particular not as closed. Thus, the connection device, in particular as a locking latch, can be used for:

[0111] Figure 1A , Figure 1B and Figure 1C The application of a variant embodiment of the proposed connecting device V on a backpack T is shown in order to releasably connect a second component A2 to a first component A1. The second component A2 is a cover on the upper side of the backpack T. The cover is connected to the first component A1 on the front side of the backpack T via a tab LS in order to close an opening on the front side of the backpack T, via which the interior of the backpack T is accessible when the cover is open. For this purpose, a second connecting element 2 of the connecting device V is provided on the lower side of the tab LS. The second connecting element 2 can be connected to the first connecting element 1 of the connecting device V on the front side of the backpack T. For example, the connecting elements 1 and 2 of the connecting device V are fixed to the components of the corresponding components A1 or A2 by sewing.

[0112] Figure 1BA backpack T is shown, which has tabs LS (not shown here again) in order to show the connecting device V in the connected state. Figure 1C Details of the first connecting element 1 covered by the second connecting element 2 can also be seen.

[0113] Figure 2 The second connecting part 2 arranged on the underside of the tab LS is shown in an enlarged view. The second connecting part 2 has in particular a rigid base body 20 which can be joined in a form-fitting manner to the first base body 10 of the first connecting part 1 of the connecting device V via a circumferentially surrounding joining section 21. A second magnetic device M2 is provided in a pin protruding from the second base body 20, the joining section 21 surrounding the pin as a circumferential edge. When the second connecting part 2 is placed on the first connecting part 1, the second magnetic device 2 interacts with the first magnetic device M1 of the first connecting part in a magnetically attractive manner in order to support the form-fitting joining of the joining section 21 of the second connecting part 2 into the first base body 10 of the first connecting part 1 and to achieve automatic assuming of the connecting position of the first and second connecting parts 1, 2 when the two base bodies 10 and 20 are sufficiently close to each other. In the connecting position, the first and second connecting parts 1, 2 are held on each other and cannot be twisted relative to each other.

[0114] exist Figure 2 In the second connecting part 2 shown in FIG. 1 , a transmission part 3 having an operating section in the form of a handle tab 30 is provided in order to introduce a force thereon for attaching the first connecting part 2 to the first connecting part 1 and, in the connected state of the first and second connecting parts 1 , 2, for releasing the two connecting parts 1 and 2 from each other. The handle tab 30, which is provided for manual actuation, is made of a soft material and transitions into a longitudinally extending, likewise soft base section 31, via which the transmission part 3 is connected to the second component A2 and, if necessary, to the tab LS of the backpack T. Accordingly, by pulling the handle tab 30, it is possible to manually act on the tab LS of the backpack T in order to close or open the lid at the upper side of the backpack T and, accordingly, to fix the second connecting part 2 on the first connecting part 1 or to separate it from the first connecting part. The base section 31, the handle tab 30 and the bridge section 34 are formed, for example, by a continuous textile or leather strap, wherein two sections lying opposite one another are fixed to one another at least at a first end point 341.

[0115] In order to support the simple and thus easy and smooth connection of the second base body 20 with its connection section 21 to the first base body 10, in particular when the connection device V is closed and stresses act on the base section 31 (in particular when the backpack T is filled), the second base body 20 of the second connecting element 2 is not arranged directly on the base section 31. Instead, the second base body 20 is arranged on a bridge section 34, for example fixed thereto by sewing, which allows the base body 20 to be displaceable relative to the base section 31 and the handle tab 30. Therefore, the bridge section 34 extends from a first end point 341 on the base section 31 in the region of the handle tab 30 to a second end point 342 in the region of the end of the base section 31, at which the base section 31 is connected to the second component A2 or transitions into the second component. The bridge section 34 is therefore fixed at the end points 341 and 342. Here, the length of the bridging section 34 between the end points 341, 342 is greater than the distance between the two end points 341 and 342 measured along the extension direction E of the base section 31, which extends from the bridging section 30 to the force introduction point at which the base section 31 transmits forces into the second component A2 or vice versa introduces forces acting on the second component A2 into the base section 31. The bridging section 34 is also made of a soft material in the present case and bridges the two end points 341 and 342, so that the bridging section 34 can be displaced transversely to the extension direction E relative to the base section 31.

[0116] In particular, according to Figure 3 As shown, in the connected state of the first and second connecting parts 1 and 2, since the second base body 20 is arranged at the bridging section 34, the displacement movement of the base section 31 caused by the force (manually) introduced at the handle tab 30 does not cause a direct joint displacement of the second base body 20. On the contrary, when a pulling force is applied to open the upper lid at the backpack T, the handle tab 30 together with the base section 31 connected thereto can first be displaced by a defined adjustment distance in the pulling direction Z without directly applying a force to the second base body 20. In addition, the bridging section 34 makes it possible that in the connected position, under a load acting on the base section 31 (for example, from the second component A2 on the base section 31), the base section 31 can be displaced toward the second base body 20 and, for example, according to Figure 3, under the effect of the load, the second base body 20 is displaced without loading the second base body 20. Therefore, by arranging the bridging section 34 at the transmission member 3, it is achieved that the load acting on the handle tab 30 or the base section 31 also does not directly cause a load acting on the second base body 20 and thus on the connection between the first connecting member 1 and the second connecting member 2. Only when the gap achieved by the bridging section 34 is exhausted, the force is introduced into the base body 20 of the second connecting member 2 via the bridging section 34, which is now under stress on one side. Correspondingly, the corresponding force is applied to the locking device V only after the gap achieved by the bridging section 34 is overcome.

[0117] Only when the handle tab 30 and thereby the base section section 31 eliminate the gap provided by the bridging section 34, the second base body 20 of the second connecting member 2 is acted upon by further pulling on the handle tab 30. The second base body 20 is still loaded into the engagement position with the first base body 10 by the attraction of the first and second magnetic devices M1 and M2 by means of the magnetic force acting in the connecting direction R. Then, by further pulling the handle tab 30 in opposition to the magnetic force, the second base body 20 is disengaged from the first base body 10 of the first connecting member 1 by lifting the rear end.

[0118] exist Figure 4 1 shows the first connecting part 1 in an enlarged scale. The first connecting part 1 with the base body 10 has an engagement device 11, which has two engagement projections 12 that are currently opposite to each other. When the second connecting part 2 is placed on the first connecting part 1, the front area of ​​the engagement section 21 of the second base body 20 engages with the engagement projections 12 in a form-fitting manner, supported by the two magnetic devices M1 and M2, so that the two connecting parts 1 and 2 are held on each other in the connection position then occupied and remain connected even when a load is applied to one or both of the connecting parts 1 and 2. Only by the above-defined displacement movement of the second base body 20 relative to the first base body 10 of the first connecting part 1 can the two base bodies 10 and 20 be disengaged again and the connecting parts 1 and 2 can be released from each other.

[0119] By arranging the second base body 2 on the bridging section 34 of the transmission element 3, corresponding to Figure 5A and Figure 5BThe illustration also simplifies the connection of the two connecting elements 1 and 2. Thus, via the bridging section 34, it is achieved that the second base body 20 can be smoothly and automatically joined to the first base body 10 even when the handle tab 30 has to be pulled with a relatively large pulling force in order to close the lid on the backpack T, for example because the backpack T is full. If, for example, the user pulls the handle tab 30 with his hand H in the pulling direction Z in order to place the second connecting element 2 on the first connecting element 1, the base body 20 can be automatically and easily snapped into the first base body 10 of the first connecting element 1 under the action of the magnetic devices M1 and M2, because the second base body 30 arranged on the bridging section 34 can be displaced in the transverse direction (transverse to the pulling direction Z) relative to the tautly tensioned base section 31 by the gap defined by the length of the flexible bridging section 34.

[0120] Therefore, if Figure 5B As shown, if a tensile force is also applied to the handle bar 30 in order to bring the second connecting part 2 completely close to the first connecting part 1 first, the two base bodies 10 and 20 can be joined to one another so that the two connecting parts 1 and 2 are held on one another.

[0121] In accordance with Figures 6 to 10 In a variant embodiment of the connecting device V, the second base body 20 of the second connecting part 2 is also held on the flexible bridging section 34, so that a gap is introduced between the second base body 20 and the actuating section in the form of a handle bar 30. Figure 5B In the embodiment variant of the invention, on the one hand, the second connecting part 2 is designed in two parts and has a coupling element 22, to which the second base body 20 is articulated via a pivot axis 23. On the other hand, the second base body 20 is not directly fixed to the bridging section 34. Instead, the flexible bridging section 34 surrounds the connecting piece 204 of the second base body 30. Thus, the strip-shaped, flexible bridging section 34 is guided through the opening in the base body 20 and surrounds the connecting piece 204 of the second base body 20 arranged at the end side between the two end points 341 and 342 of the bridging section 34.

[0122] exist Figures 6 to 10 In a variant embodiment, the first end point 341 of the bridge section 34 is also arranged in the region of the handle tab 30 on the base section 31, so that forces can also be introduced from the handle tab 30 into the bridge section 34 via this. The second end point 342 is spaced apart from the first end point 341 in the extension direction E of the base section 31, at which the bridge section 34 is now again connected to the flexible base section 31 in order to form a ring fixed to the base section 31.

[0123] The base section 31 transitions into an end ring in the extension direction E during further development, via which the base section 31 surrounds and holds the connecting piece 223 on the coupling element 22. The coupling element 22 in turn serves to attach the second connecting part 2 to the second component A2, which is designed in this case in the manner of a belt.

[0124] By virtue of the pivotability of the second base body 20 relative to the coupling element 22 of the second connecting element 2, the second connecting element can be joined to the first base body 10 of the first connecting element 1 of the connecting device V, which is Figure 7 . The first base body 10 of the first connecting element 1 is fixed to the first component A1, which is also designed in the present case as a belt type. Correspondingly, the two connecting elements 1 and 2 can act together in the manner of a buckle to connect the two belt ends to each other.

[0125] A coupling device 11 with a coupling projection 11 is provided on the first base body 10 of the first connecting member 1. A coupling section 21 of the second base body 20, which is formed at the end of the longitudinal side of the second base body 20 and faces the coupling element 22, can be coupled with the single coupling projection 12 of the first base body 10. Therefore, a coupling gap is provided between the end of the longitudinal side of the second base body 20 and the coupling element 22, into which the coupling projection 12 can be coupled when the second connecting member 2 is conventionally placed on the first base body 10 of the first connecting member 1. Here, the first and second connecting members 1 and 2 are magnetically supported to occupy a connection position, in which the coupling section 21 is overlapped by the coupling projection 12, via the first and second magnetic devices M1, M2 of the two base bodies 10, 20. In the connection position, the second connecting member 2 is only possible to release from the first connecting member 1 against the magnetic forces exerted by the first and second magnetic devices M1, M2 when a tilting movement of the second base body 20 relative to the first base body 10 is carried out about the pivot axis 23. The loosening process Fig.10 Further shown in .

[0126] If the user pulls the handle tab 30 along the pulling direction Z with his hand H and thereby moves the second base body 20 according to Fig.10 2 and 3. The two connecting parts 1 and 2 can then be released from each other by pivoting about the pivot axis 23 in the pivot direction L as shown in the figure. By holding the base body 20 on the soft bridging section 34, the tensile force introduced at the handle tab 30 is only transferred back to the connecting piece 204 and thus to the base body 20 after bridging the defined gap. Therefore, before the force is introduced into the second base body 20, the handle tab 30 must first be displaced to a defined extent.

[0127] Likewise, in the case of a substrate having a bridging section 34 and a second base body 2 attached thereto, Figures 6 to 10 In the design of the connecting device V, it is also achieved that in the connection position of the first and second connecting parts 1, 2, the base section 31 can be displaced toward the second base body 20 when a load acts on the base section 31 (for example, from the second component A2). Therefore, when the connecting device V is closed, the load acting on the base section 31 does not directly lead to the introduction of force into the second base body 20 and, via this, a direct load on the connection between the first connecting part 1 and the second connecting part 2. In addition, in the embodiment variant shown, in the connection position, the load always acts on the connection of the first and second locking parts 1, 2 and thus on the locking provided thereby, through the design of the transmission part 3 and the bridging section 34 and the attachment of the transmission part 3 to the elements of the second composite component 2. In this case, in particular, the operating section in the form of the handle tab 30 is kept free of load by the bridging section 34.

[0128] With the help of Fig. 8A and Figure 8B The closing of the connecting device V is explained in more detail. When the second connecting part 2 required for this is placed on the first connecting part 1, in order to connect and hold the two components A1 and A2 to each other via the connecting device V, the bridging section 34 allows the second base body 20 to be snapped onto the first base body 10 again by a displacement movement of the second base body 20 toward the possibly tightened base section 31 and the handle tab 30. Then, Fig. 9 The connected positions of the first and second locking members 1 and 2 are shown.
