Description

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

[0002] Such a connecting device comprises a first connecting part assigned to a first assembly, which has a first base body and an engagement device with at least one engagement projection. The connecting device further comprises a second connecting part assigned to a second assembly, which can be inserted onto the first connecting part and has a second base body with at least one engagement section arranged on the second base body. The at least one engagement section can be brought into engagement with the engagement device of the first connecting part, so that in a connected position, the first connecting part and the second connecting part are held against one another.

[0003] The connecting device is designed 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 interact in a magnetically attractive manner to assist in the attachment of the first connecting part and the second connecting part to one another.

[0004] In a closure device known from EP 3 616 553 A1 for detachably connecting two parts, a first connecting part can be attached to a second connecting part to connect the connecting parts together. A shoelace is arranged on one of the connecting parts, which can be tightened by connecting the connecting parts together.

[0005] EP 3 192 388 B1 discloses a closure device 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] US10758019B2 discloses a connecting device according to the preamble of claim 1.

[0007] In the connecting device, the first connecting part is assigned to a first assembly. The second connecting part, in contrast, is assigned to a second assembly. By closing the connecting device, i.e. by placing the connecting parts against one another, the assemblies can be connected to one another. One or both of the assemblies can, for example, be designed as a section of material, for example made of a textile material, a leather material or even a section of a plastic surface, for example a belt or a section of a piece of clothing, although this is not mandatory and it is also conceivable for one or both of the assemblies to be formed by a rigid object. The proposed solution is based on the object of providing a connecting device that enables assemblies to be connected to one another in a simple and reliable manner.

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

[0009] A proposed connecting device comprises, among other things, a first connecting part assigned to a first assembly, which has a first base body and an engagement device with at least one engagement projection, and a second connecting part assigned to a second assembly, which can be attached to the first connecting part and has a second base body with at least one engagement section arranged on the second base body. The at least one engagement section can be brought into engagement with the engagement device of the first connecting part, so that in a connected position (of the first and second connecting parts), the first connecting part and the second connecting part are held together. The first connecting part and the second connecting part each have a magnetic device which interact with one another in a magnetically attractive manner to assist the attachment of the first connecting part and the second connecting part.In order to be able to manually or mechanically attach the second connecting part to the first connecting part and to detach it from the second connecting part again in the connected position, the second connecting part is connected to a handling section. The second connecting part can be attached to the first connecting part via the handling section. Furthermore, an (opening) force can be introduced into the handling section when the first and second connecting parts are in the connected position in order to disengage the engagement section from the engagement device and to detach the second connecting part from the first connecting part.

[0010] In connecting devices known to date on the market, the handling section is typically connected to a base section or merges into such a base section on which the second main body of the second connecting part is provided. A displacement of the handling section is thus accompanied by a direct displacement of the second main body, wherein the connection to the second assembly is typically also established via the base section or the base section is part of the second assembly. The handling section is therefore provided to attach the second connecting part to the first connecting part and, when the first and second connecting parts are in the connected position, to introduce a force therethrough in order to disengage the engagement section from the engagement device.

[0011] For example, by pulling on the handling section, the second connecting part with the second base body and a section of the second assembly connected thereto can be brought closer to the first base body of the first connecting part, and the two connecting parts can be engaged with each other to connect the two assemblies via the connecting device. For example, a tensile force is introduced via the handling section to bring a strap carrying the second connecting part, a tab or flap carrying the second connecting part, or a comparable section of a second assembly closer to the first connecting part and secure it thereto.If a comparatively large tensile force must be applied, for example because a container or item of clothing whose two components are to be held together is heavily filled or expanded, and thus the second connecting part must be attached to the first connecting part against a tensioning force, the engagement of the engagement section on the engagement device may be difficult. In such a situation, the release of the second connecting part from the first connecting part may also be difficult due to the load acting on the connecting device, particularly if a tensioning force counteracting the release of the connection acts not only directly on the handling section but also on the second base body of the second connecting part.Furthermore, in the connected position of the first and second connecting parts, when the second base body is arranged on the base section connected to the second assembly, a load acting on the base section via the second assembly acts directly on the second base body and thus on the connection of the first and second connecting parts.

[0012] Against this background, for transmitting the force to the second connecting part in order to disengage the engagement section from the engagement device and to detach the second connecting part from the first connecting part, a transmission part is provided on the connecting device, which transmission part comprises the handling section, a base section connected to the handling section and extending along an extension direction, and a bridge section connected to the base section at a first end point. The bridge section extends between the first end point and a second end point spaced apart from the first end point in the extension direction, with a length that is greater than the distance between the two end points.The second base body is held on this bridge section, wherein the bridge section can then be displaced with the second base body relative to the base section and the handling section when the second connecting part is attached to the first connecting part.

[0013] Due to the displaceability of the bridge section and the second base body provided thereon, the at least one engagement section of the second base body can, for example, be more easily brought into engagement with the engagement device of the first base body with magnetic support, since a displacement movement of the second base body relative to the base section and the handling section is permitted for this purpose. Even under tension on the handling section and the base section, a displaceability of the second base body is thus specifically permitted, for example, to allow it to snap onto the first base body with magnetic support.

[0014] When the first and second connecting parts are connected, a force can be introduced via the handling section to disengage the engagement section from the engagement device and to detach the second connecting part from the first connecting part. For example, a force introduced at the handling section can be transmitted via the base section into the bridge section and, in turn, to the second base body.

[0015] In one embodiment, a defined amount of play of the second base body relative to the handling section is provided via the bridge section. This means that the second base body can be displaced by a predetermined amount relative to the handling section. This allows the second base body to be displaced independently of and relative to the handling section when the second connecting part is attached to the first connecting part, within limits defined by the bridge section. Furthermore, when the first and second connecting parts are in the connected position, when a load acts on the base section (e.g. from the second assembly to the base section), the base section can be displaced via the bridge section to the second base body. As a result, in the connected position, not every load acting on the second assembly and the base section connected to it is transferred directly to the second base body.In the connected position, a decoupling of the base section and the second base body is achieved to a certain degree via the bridge section.

[0016] The bridge section can also limit the rotatability of the second base body relative to the handling section. If the second base body is provided on a displaceable bridge section extending between the two end points, the rotatability of the second base body relative to the handling section can be relatively easily limited, for example, by the length of the bridge section and / or its rigidity.

[0017] In principle, the length bridged by the bridge section between the first endpoint and the second endpoint is smaller than the total length of the bridge section between the first endpoint and the second endpoint. The second endpoint can also be provided on the base section, so that the bridge section extends between two areas of the base section. However, this is by no means mandatory. For example, a second endpoint can also be provided on a component of the second assembly connected to the base section.

[0018] In principle, a tensile force introduced at the handling section and acting along a tensile direction for attaching the second connecting part to the first connecting part can be transmitted via the base section. The bridge section can be displaceable relative to the base section along a connecting direction inclined to the tensile direction, in particular perpendicular, in order to engage the engagement section with the engagement device. Thus, a comparatively large tensile force (in particular manually) can be applied along the tensile direction in order to bring the first and second connecting parts sufficiently close together so that - supported by the magnetic interaction of the first and second magnetic devices - the engagement section engages with the engagement device and the first and second connecting parts can be transferred into the connected position.By making the second base body with the bridge section displaceable relative to the base section loaded with the tensile force, the second base body can be brought closer to the first base body to a predetermined minimum distance in order to achieve this engagement and a concomitant snapping of the second base body onto the first base body without the corresponding tensile force acting on the second base body itself.

[0019] The bridge section is, for example, made of a flexible material or designed to be elastically displaceable. The manufacture of the bridge section from a flexible material includes, for example, the bridge section being made of a flexible material section, for example, a flexible, particularly textile, fabric section, a leather fabric section, or a plastic surface section.

[0020] In one embodiment, the bridge section can be constructed from multiple elements consisting of rigid and / or flexible elements. The bridge section can be displaceable by adjusting the rigid and / or flexible elements relative to one another. For example, in this context, the bridge section can comprise a multi-link chain, in particular, be formed by a multi-link chain.

[0021] The second base body can be fixed to the bridge section. This includes, in particular, the second base body being sewn to a flexible material of the bridge section.

[0022] In an alternative embodiment, the second base body comprises a connecting section which is at least partially encompassed, in particular engaged behind, by a bridge section made of a flexible material and / or constructed in multiple sections. In this case, the second base body is therefore not directly rigidly fixed to the bridge section. Rather, the partial encompassing of the bridge section ensures that the second base body is held on the bridge section and can thereby be displaced relative to the handling section. Due to the partial encompassing of the second base body by the flexible and / or multi-section bridge section, a force can nevertheless be transmitted from the bridge section to the second base body at the connecting section in order to disengage the engagement section from the engagement device and, for this purpose, to displace the second base body relative to the first base body.

[0023] In principle, it can be provided that, in the connected position of the first and second connecting parts, the second base body is tiltable relative to the first base body in order to disengage the engagement section from the engagement device. The first and second connecting parts are therefore configured here such that the second base body must execute a pivoting movement relative to the first base body in order to disengage the engagement section from the engagement device. The transmission part, which in particular has the bridge section, is accordingly provided to transmit a force to the second connecting part in the connected position, which force leads to a pivoting movement of the second base body relative to the first base body.The second base body is consequently tiltable relative to the first base body to enable the at least one engagement portion and the at least one engagement projection to be disengaged in order to separate the first connecting part and the second connecting part from one another. In this context, it can be provided, for example, that the second base body can be lifted from the first base body on a side (of the second base body) facing away from the at least one engagement projection for tilting relative to the first base body.

[0024] Conversely, for assuming the connected position and engaging the engagement portion with the engagement device, a tilting movement of the second base body relative to the base portion and handling portion may be permitted when attaching the second connecting part to the first connecting part via the bridge portion.

[0025] In one possible embodiment, the first connecting part can additionally have a blocking section rigidly arranged on the first base body, which is designed to cooperate with the second connecting part in the connected position in order to block the engagement of the at least one engagement section with the at least one engagement projection counter to the engagement direction. When the connecting parts are attached, the at least one engagement section of the second connecting part engages with the at least one engagement projection of the first connecting part in the engagement direction, so that in the connected position there is a positive or non-positive connection between the connecting parts and the connecting parts are thus held against one another in a load-bearing manner by the engagement of the at least one engagement section with the at least one engagement projection.The engagement between the at least one engagement section of the second connecting part and the at least one engagement projection of the first connecting part is secured in the connected position by the blocking section of the first connecting part, which is rigidly formed on the first base body of the first connecting part, in that the blocking section cooperates in a blocking manner counter to the engagement direction with an associated section of the second connecting part, and the at least one engagement section cannot therefore be moved counter to the engagement direction towards the at least one engagement projection, at least not without removing the blocking. Due to the blocking effect of the blocking section, the at least one engagement section is thus blocked in its engagement with the at least one engagement projection.

[0026] In a configuration with a blocking section, the connecting parts could be held in the connected position due to the magnetic effect of the magnetic devices in such a way that the connecting parts are blocked from one another by the blocking section of the first connecting part, counter to the direction of engagement. Thus, the connecting parts cannot be separated from one another by a (pure) sliding movement counter to the direction of engagement.

[0027] In one possible embodiment, the second connecting part, as explained above, can be tilted relative to the first connecting part to release the connecting parts from one another. In a variant with a blocking section, the second connecting part can then be tilted relative to the first connecting part to release the connecting parts from one another, in order to move the second connecting part toward the first connecting part in a tilting plane defined by the closing direction and the engagement direction, such that the second connecting part can be moved toward the blocking section on the first base body, counter to the engagement direction.By tilting the second connecting part relative to the first connecting part, the blocking effect of the blocking section can be canceled, so that the second connecting part can be moved over the blocking section and thus the at least one engagement section of the second connecting part can be brought out of engagement with the at least one engagement projection of the first connecting part.

[0028] The blocking effect of a blocking section rigidly arranged on the first base body of the first connecting part makes it possible to ensure that the second connecting part cannot be moved linearly against the engagement direction, but rather must be tilted in a tilting plane spanned by the closing direction and the engagement direction in order to separate the connecting parts from one another. The tilting movement can occur about a defined tilting axis. However, the tilting movement can also occur along a curved path of movement located in the tilting plane, whereby the second connecting part is tilted relative to the first connecting part as a result of the tilting movement. The tilting movement can be superimposed by a linear movement against the engagement direction and / or against the closing direction.

[0029] It should be noted that the connecting parts can be tilted relative to one another to separate them. The connection between the connecting parts is also established not in a linear closing movement, for example, but rather by the connecting parts being placed against one another in a wobbling manner while tilted relative to one another and moved into engagement. During the establishment of the connection, the second connecting part can also tilt relative to the first connecting part to enable the at least one engagement portion of the second connecting part to engage the at least one engagement projection of the first connecting part.

[0030] In the connected position, the second connecting part can, in one possible embodiment, be rotatable about the closing direction relative to the first connecting part. This can, on the one hand, enable the connecting parts to be placed against one another in an angularly tolerant manner. It is also possible to rotate the second connecting part relative to the first connecting part when the connecting parts are in the connected position. Upon rotation, the at least one engagement section and the at least one engagement projection retain their engagement. Furthermore, the engagement is blocked by the blocking section even during rotation. Rotating the connecting parts about the closing direction relative to one another in the connected position therefore does not lead to the connecting parts becoming separated from one another.

[0031] The ability to rotate between the connecting parts in the connected position can enable any desired rotational movement through any desired angle. However, it is also conceivable that the movement of the connecting parts is limited to a predetermined angle of rotation, for example, by stops or the like. The angle of rotation is preferably greater than 10°, more preferably greater than 20°, particularly preferably greater than 45° or even greater than 90°.

[0032] Although not mandatory, the at least one engagement projection can be provided on the first base body of the first connecting part so that it is rigid and non-deformable (under a load acting as intended). If the at least one engagement projection is formed on the first base body of the first connecting part so that it is rigid and non-deformable (under a load acting as intended), the engagement projection can, under certain circumstances, absorb and dissipate forces more reliably when engaging with the at least one engagement section of the second base body. The at least one engagement projection can be formed integrally with the first base body of the first connecting part, wherein the first base body is designed to be rigid and non-deformable overall.

[0033] Alternatively or additionally, the engagement portion can be provided rigidly on the second base body. This includes, in particular, the engagement portion being rigidly formed on the second base body. For example, the second base body of the second connecting part, with the at least one engagement portion formed thereon, is rigid and non-deformable and, for this purpose, is formed, for example, from metal or a hard plastic material.

[0034] In this context, "non-deformable" refers to a substantially rigid geometry and material selection of the base body, which ensures that the base body of the first connecting part, with the engagement projection formed thereon, does not deform under a specified load; thus, the base body is not 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 off the first connecting part on a side facing away from the at least one engagement projection in the opposite direction to the closing direction in order to tilt it relative to the first connecting part. In this case, the second connecting part in the connected position can also engage with the at least one engagement projection on the first base body of the first connecting part via the at least one engagement section provided on the second base body, wherein this engagement takes place in a front region of the second connecting part - viewed in relation to the engagement direction. With a rear region with respect to the engagement direction, the second connecting part in the connected position can be lifted off the first connecting part in the opposite direction to the closing direction in order to tilt the second connecting part relative to the first connecting part.If a blocking section is provided, the second connecting part can be lifted off the first connecting part in the connected position counter to the closing direction in order to tilt the second connecting part relative to the first connecting part and thereby cancel the blocking effect of the blocking section of the first connecting part, so that the second connecting part can be moved to the blocking section of the first connecting part and the at least one engagement section can be brought out of engagement from the at least one engagement projection counter to the engagement direction.

[0036] For example, the at least one engagement section of the second connecting part is formed by an edge section that can be brought into engagement with the at least one engagement projection. Alternatively or additionally, the at least one engagement section of the second connecting part can extend circumferentially on the first base body. In this case, the second connecting part can in particular have a single engagement section that extends circumferentially on the second base body and projects (radially) outwards. The engagement section is undercut in that a further section adjoining the engagement section springs back inwards relative to the engagement section and thus enables the engagement section to be brought into engagement with the at least one engagement projection of the engagement device of the first connecting part.

[0037] If the second base body of the second connecting part is rotationally symmetrical on a pin forming the engagement section, the engagement section projects radially outwards and runs in a circle around the pin.

[0038] However, the second base body can also be non-rotationally symmetrical. In this case, the engagement section can, for example, be angular, for example, square, around the base body.

[0039] The first assembly and / or the second assembly can be made, for example, from a flexible fabric section, for example from a textile fabric, a leather fabric, a plastic surface section, or another material. The first assembly and / or the second assembly can be formed, for example, by a belt, a band, a part of a garment, a part of a bag, a backpack, or another container, or an entirely different assembly. Such a fabric section can have very different material thicknesses; with greater fabric thicknesses or a harder material, the fabric can be perforated to attach the connecting device.

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

[0041] In the connecting device, for example, one or both of the connecting parts can be connected to the respective associated assembly via a seam connection, although other types of connection between an assembly and an associated connecting part are also possible. To create a seam connection, a sewing thread can be passed through a sewing area on the respective base body to create a seam between the respective connecting part and the associated assembly, thus connecting the connecting part to the assembly.

[0042] The connecting parts can be placed against one another to connect the assemblies and, in a connected position, are arranged relative to one another such that they are held together by the magnetic interaction of the magnetic devices and also by the engagement of the engagement portion of the second connecting part with the engagement device of the first connecting part. In the normal operating state, the connecting parts are connected to the respectively assigned assembly. To close the connecting device, the connecting parts are placed against one another with magnetic assistance from a magnetic attraction force of the magnetic devices, such that the at least one engagement portion of the second connecting part engages with the at least one engagement projection of the engagement device of the first connecting part, thus establishing a connection between the connecting parts.

[0043] To close the connecting device, the connecting parts can, for example, be placed against each other along a closing direction. Along the closing direction, the magnetic devices interact magnetically, so that the connecting parts are drawn toward each other with magnetic assistance. However, it is also possible to place the connecting parts along a direction different from the closing direction.

[0044] The connection between the connecting parts in the connected position can be free of play or with play.

[0045] The engagement of the at least one engagement section with the at least one engagement projection in the connected position can be positively or non-positively engaged. In particular, the at least one engagement section and / or the at least one engagement projection can have surfaces extending perpendicular to a closing direction or surfaces extending obliquely to the closing direction, which face each other in the connected position and establish a positively or non-positively engaged connection, with or without play.

[0046] The retention of the connecting parts in the connected position can act along the closing direction and / or along a direction transverse or oblique to the closing direction.

[0047] For example, a load direction along which belt forces act can be perpendicular or diagonal to the closing direction. However, a load direction can also act, for example, opposite to the closing direction.

[0048] The joining of the connecting parts to one another is magnetically assisted. 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 particularly assist the joining of the connecting parts to one another. The magnetic devices, for example, exert a magnetic attraction along a closing direction, so that the magnetic devices exert a magnetic attraction force along the closing direction and pull the connecting parts toward one another along the closing direction when they are joined.

[0049] The magnetic devices can, for example, each be formed by a permanent magnet. However, it is also possible to design one of the magnetic devices as a permanent magnet and the other as a magnetic armature, thus forming a passively magnetic (ferromagnetic) element.

[0050] In one embodiment, the at least one engagement section is formed by an edge section that can be brought into engagement with the at least one engagement projection. The at least one engagement section can be formed by an outwardly facing edge section that extends circumferentially on the second base body. In another embodiment, the at least one engagement section can not be formed circumferentially on the base body, but rather, for example, only on one end face. The edge section can delimit the second base body outwardly, viewed along the second plane.

[0051] Because the at least one engagement section can be brought into engagement with the at least one engagement projection parallel to a second plane along which the engagement section extends on the base body, or along a direction extending obliquely thereto, the at least one engagement section and the at least one engagement projection, viewed along a direction perpendicular to this second plane, at least partially coincide with one another. The engagement (also) creates a hold between the connecting parts along the direction perpendicular to the second plane.

[0052] In one embodiment, the at least one engagement portion of the second connecting part, viewed along a second plane, projects outward relative to another portion of the second base body. The second plane can, for example, be directed approximately perpendicular to a closing direction along which the connecting parts can be joined to close the connecting device (it being possible for the connecting parts to also be joined to one another in a direction deviating from the closing direction). Transverse to the closing direction, the at least one engagement portion projects from another portion of the second base body of the second connecting part.The at least one engagement section is thus undercut with respect to a direction perpendicular to the second plane, in that the further section springs back relative to the engagement section and thus enables engagement with the at least one engagement projection of the engagement device of the first connecting part.

[0053] Surfaces of the engagement portion 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 with each other without play or with play, can be aligned along a second plane along which the engagement portion extends on the base body, or obliquely to the second plane in order to produce a positive or force-locking connection.

[0054] The connection can be established via the at least one engagement section and the at least one engagement projection alone. However, it is also conceivable that additional connection partners contribute to establishing the connection.

[0055] In one embodiment, the second base body has two engagement sections formed on edges facing away from each other. Thus, (at least) two engagement sections are formed on the base body, which are formed on different edges of the base body. The engagement sections are each undercut in that the engagement sections protrude outwardly and a further section of the base body adjoining the respective engagement section is recessed such that the respective engagement section can be brought into engagement with an associated engagement projection of the engagement device of the first connecting part in order to close the connecting device.

[0056] In one embodiment, the at least one engagement projection of the first connecting part is rigidly formed on the first base body. The at least one engagement section of the second connecting part can be brought into engagement with the at least one engagement projection of the first connecting part, for example, along an engagement direction that is parallel or oblique to a first plane along which the at least one engagement projection extends. The at least one engagement projection of the first connecting part is thus rigidly and non-elastically formed on the first base body of the first connecting part.

[0057] To close the connecting device, the at least one engagement projection can be brought into engagement with the at least one engagement section rigidly formed on the second base body of the second connecting part. This is preferably achieved by pushing the at least one engagement section into engagement with the at least one engagement projection in an engagement direction parallel or oblique to the first plane. In the connected position, the at least one engagement section is thus engaged (with or without play) with the at least one engagement projection, so that the connecting parts are held in position relative to one another along a direction perpendicular or oblique to the first plane via the engagement of the at least one engagement section with the engagement projection.Mutually facing surfaces of the at least one engagement portion and the at least one engagement projection can be aligned along the first plane or also obliquely to the first plane.

[0058] In one embodiment of the connecting device, one or more engagement projections are rigidly formed on the first base body of the first connecting part. The second connecting part can be engaged with the at least one engagement projection by bringing the at least one engagement section of the second connecting part into engagement with the at least one engagement projection of the first connecting part. The first connecting part and the second connecting part are attached to one another, for example, along a closing direction, along which magnetic devices of the connecting parts provide a magnetic attraction force, so that the connecting parts are drawn toward one another along the closing direction.In contrast, the engagement of the at least one engagement section of the second connecting part with the at least one engagement projection of the first connecting part occurs along an engagement direction that is directed transversely or obliquely to the closing direction. In the connected position, the at least one engagement section engages the at least one engagement projection in a form-fitting or force-fitting manner, so that the connecting parts are held together.

[0059] In one embodiment, the first connecting part has two engagement projections which are spaced apart from one another transversely to the closing direction and transversely to the engagement direction.

[0060] The at least one engagement section can have a curved (arc-shaped) shape. The at least one engagement section can be formed circumferentially on the second base body or, alternatively, can be formed only over an arc section, for example, over an arc section of less than 180°, on the second base body. If the engagement section extends circumferentially on the second base body, the engagement section can be formed in a circular shape or can also have a different shape, for example, an angular shape, for example, a polygonal shape, for example, a square or hexagonal shape.

[0061] Regardless of the specific design of the first connecting part and the second connecting part, in particular of the at least one engagement projection of the engagement device of the first connecting part and the at least one engagement section of the second connecting part, the connecting parts can be designed such that, in the connected position, the second connecting part can be rotated relative to the first connecting part in a direction perpendicular to the first plane. In the connected position, the connecting parts can thus be rotated relative to one another.

[0062] Other configurations of the connecting parts are also conceivable and possible, wherein the at least one engagement projection can be arranged rigidly or movably relative to the first base body of the first connecting part and / or wherein the at least one engagement section can be arranged rigidly or movably relative to the second base body of the second connecting part.

[0063] In principle, the first connecting part and / or the second connecting part can be designed in multiple parts. This includes, in particular, the first connecting part and / or the second connecting part comprising at least two elements connected to one another in an articulated manner.

[0064] The proposed solution further relates to a system comprising a first assembly and a second assembly, wherein the first and second assemblies can be connected using a variant of a proposed connecting device. The assemblies can in turn be part of a higher-level assembly or connected to one another via additional elements in an overall system. In a proposed system, the base section of the transmission part, to which the handling section is connected, can be connected to the second assembly or at least partially or completely formed by a section of the second assembly.

[0069] The Figures 1A , 1B and 1Cshow the use of an embodiment of a proposed connecting device V on a backpack T, in order to detachably connect a second assembly A2 to a first assembly A1. The second assembly A2 is a flap on the top side of the backpack T. This flap is to be connected to the first assembly A1 on the front side of the backpack T via a tab LS in order to close an opening on the top side of the backpack T, through which the interior of the backpack T is accessible when the flap is open. For this purpose, a second connecting part 2 of the connecting device V is provided on the underside of the tab LS. This second connecting part 2 can be connected to a first connecting part 1 of the connecting device V on the front side of the backpack T. For example, the connecting parts 1 and 2 of the connecting device V are fixed to a component of the respective assembly A1 or A2 by sewing.

[0070] The Figure 1B shows the backpack T with the flap LS no longer shown here, in order to show the connecting device V in a connected state. In the Figure 1C Details of the first connecting part 1, which is concealed by the second connecting part 2, are also visible.

[0071] The Figure 2shows an enlarged view of the second connecting part 2 provided on an underside of the tab LS. The second connecting part 2 has, among other things, a rigid base body 20, which can be brought into positive engagement with a first base body 10 of the first connecting part 1 of the connecting device V via a circumferentially extending engagement section 21. A second magnetic device M2 is provided in a pin protruding from the second base body 20, around which the engagement section 21 extends as a circumferential edge.When the second connecting part 2 is attached to the first connecting part 1, this second magnetic device 2 interacts with a first magnetic device M1 of the first connecting part in a magnetically attractive manner to support the positive engagement of the engagement section 21 of the second connecting part 2 into the first base body 10 of the first connecting part 1 and to achieve an automatic assumption of the connected position of the first and second connecting parts 1 and 2 when the two base bodies 10 and 20 are sufficiently close to one another. In the connected position, the first and second connecting parts 1, 2 are held together and cannot be rotated relative to one another.

[0072] In the Figure 2The second connecting part 2 shown is provided with a transmission part 3 having a handling section in the form of a gripping tab 30, to which a force is applied to attach the first connecting part 2 to the first connecting part 1 and, when the first and second connecting parts 1 and 2 are connected, to which a force is applied to release the two connecting parts 1 and 2 from one another. The gripping tab 30, which is provided here for manual engagement, is made of a flexible material and merges into an elongated, likewise flexible base section 31, via which the transmission part 3 is connected to the second assembly A2 and, if applicable, the tab LS of the backpack T.Accordingly, by pulling on the handle tab 30, the tab LS of the backpack T can be manually actuated to close or open the flap on the top of the backpack T and accordingly to attach or detach the second connecting part 2 to the first connecting part 1. The base section 31, the handle tab 30, and the bridge section 34 are formed, for example, by a continuous textile strap or leather strap, in which two opposing sections are fixed to each other at least at the first end point 341.

[0073] In order to support a simple and therefore smooth engagement of the second base body 20 with its engagement section 21 on the first base body 10, particularly when closing the connecting device V and a tension acting on the base section 31 (especially when the backpack T is fully filled), the second base body 20 of the second connecting part 2 is not provided directly on the base section 31. Rather, 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 displaced with respect to the base section 31 and the handle tab 30.In the present case, the bridge section 34 extends from a first end point 341 on the base section 31 in the region of the gripping 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 assembly A2 or merges into it. The bridge section 34 is therefore fixed at the end points 341 and 342. The length of the bridge section 34 between these end points 341, 342 is greater than a distance between the two end points 341 and 342, measured along an extension direction E of the base section 31, which points from the bridge section 30 to a force introduction point at which the base section 31 transmits a force to the second assembly A2 or, conversely, a force acting on the second assembly A2 is introduced into the base section 31.In the present case, the bridge section 34 is also made of a flexible material and bridges the two end points 341 and 342, so that the bridge section 34 is displaceable transversely to the extension direction E relative to the base section 31.

[0074] As can be seen in particular from the Figure 3As illustrated, in the connected state of the first and second connecting parts 1 and 2, due to the provision of the second base body 20 on the bridge section 34, a displacement movement of the base section 31 as a result of a force (manually) introduced on the gripping tab 30 does not lead to an immediate displacement of the second base body 20. Rather, the gripping tab 30 with the base section 31 connected thereto can, when a tensile force is applied to open the upper flap on the backpack T, initially be displaced by a defined adjustment path along a pulling direction Z, without a force acting directly on the second base body 20. In addition, the bridge section 34 ensures that in the connected position, when a force is applied to the base section 31 (e.g.from the second assembly A2 on the base section 31) acting load, the base section 31 can be displaced to the second base body 20 and, for example, as shown in the . Figure 3under the effect of this load relative to the second base body 20, without loading the second base body 20. The provision of the bridge section 34 on the transmission part 3 thus ensures that a load on the gripping tab 30 or the base section 31 does not directly lead to a load on the second base body 20 and thus on the connection between the first and second connecting parts 1 and 2. Only when the play made possible by the bridge section 34 is exhausted is force introduced via the bridge section 34, which is now under tension on one side, into the base body 20 of the second connecting part 2. Accordingly, corresponding forces only act on the locking device V after the play made possible by the bridge section 34 has been overcome.

[0075] Only when the grip tab 30 and thus the base section 31 have bridged a play predetermined by the bridge section 34 does further pulling on the grip tab 30 act on the second base body 20 of the second connecting part 2. The second base body 20 is still loaded into an engaged position with the first base body 10 by the attractive effect of the first and second magnetic devices M1 and M2 with a magnetic force acting in a connecting direction R. Counter to this magnetic force, by further pulling on the grip tab 30, the second base body 20 is then brought out of engagement with the first base body 10 of the first connecting part 1 by lifting a rear end.

[0076] The first connecting part 1 is shown in an enlarged scale in the Figure 4shown. The first connecting part 1 with its base body 10 has an engagement device 11 with, in this case, two opposing engagement projections 12. When the second connecting part 2 is placed against the first connecting part 1, a front region of the engagement section 21 of the second base body 20 is brought into positive engagement with these engagement projections 12 - supported by the two magnetic devices M1 and M2 - so that the two connecting parts 1 and 2 are held together in the then assumed connected position and remain connected even when a load is applied to one or both of the connecting parts 1 and 2. Only through the defined displacement movement of the second base body 20 relative to the first base body 10 of the first connecting part 1, as explained above, can the two base bodies 10 and 20 be disengaged again and the connecting parts 1 and 2 be released from one another.

[0077] The provision of the second base body 2 on the bridge section 34 of the transmission part 3 is described in accordance with the illustrations of Figures 5A and 5Balso facilitates the connection of the two connecting parts 1 and 2. Thus, via the bridge section 34, the second base body 20 can be brought into engagement with the first base body 10 smoothly and automatically, even if the grip tab 30 has to be pulled with a comparatively large pulling force in order to close the flap on the backpack T, for example, because the backpack T is completely full.If, for example, a user pulls with one hand H on the grip tab 30 along a pulling direction Z in order to attach the second connecting part 2 to the first connecting part 1, the base body 20 can easily snap automatically into the first base body 10 of the first connecting part 1 under the action of the magnetic device M1 and M2, since the second base body 30 provided on the bridge section 34 can be displaced in a transverse direction (transverse to the pulling direction Z) relative to the taut base section 31 by the play defined by the length of the pliable bridge section 34.

[0078] As in the Figure 5B As shown, the two base bodies 10 and 20 can thus be brought into engagement with one another and thus the two connecting parts 1 and 2 can be held together if a tensile force is still to be applied to the grip tab 30 in order to bring the second connecting part 2 closer to the first connecting part 1.

[0079] In a variant of a connecting device V according to the Figures 6 to 10 A second base body 20 of a second connecting part 2 is also held on a flexible bridge section 34 in order to introduce a play between the second base body 20 and a handling section in the form of a gripping tab 30. In deviation from the embodiment of the Figures 1 to 5BHere, 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 hinged via a pivot axis 23. On the other hand, the second base body 20 is not directly fixed to the bridge section 34. Rather, the flexible bridge section 34 engages around a connecting web 204 of the second base body 30. Thus, here, the band-shaped, flexible bridge section 34 is guided through an opening in the base body 20 and, between two end points 341 and 342 of the bridge section 34, engages around the connecting web 204 provided at the end of the second base body 20.

[0080] The first end point 341 of the bridge section 34 is also in the variant of the Figures 6 to 10in the area of ​​the grip tab 30 on the base section 31, so that a force from the grip section 30 can also be introduced into the bridge section 34. The second end point 342, at which the bridge section 34 is again connected to the flexible base section 31 in the present case to form a loop fixed to the base section 31, is spaced from the first end point 341 in the extension direction E of the base section 31.

[0081] The base section 31 continues in the direction of extension E into an end loop, via which the base section 31 engages around a connecting web 223 on the coupling element 22 and is held thereto. The coupling element 22, in turn, serves to connect the second connecting part 2 to a second assembly A2, which is designed here in the manner of a belt strap.

[0082] Due to the pivotability of the second base body 20 relative to the coupling element 22 of the second connecting part 2, the second connecting part can be brought into engagement with a first base body 10 of a first connecting part 1 of the connecting device V, which in the Figure 7 shown in a single view. The first base body 10 of this first connecting part 1 is attached to a first assembly A1, which in this case is also designed in the manner of a belt strap. Accordingly, the two connecting parts 1 and 2 can interact in the manner of a belt buckle to connect two belt ends to one another.

[0083] An engagement device 11 with an engagement projection 12 is provided on the first base body 10 of the first connecting part 1. An engagement portion 21 of the second base body 20, which is formed at a longitudinal end of the second base body 20 and faces the coupling element 22, can be engaged with this individual engagement projection 12 of the first base body 10. Thus, an engagement gap is provided between the longitudinal end of the second base body 20 and the coupling element 22, into which engagement gap the engagement projection 12 can engage when the second connecting part 2 is attached to the first base body 10 of the first connecting part 1 as intended. The assumption of the connected position of the first and second connecting parts 1 and 2 is magnetically supported by first and second magnetic devices M1 and M2 of the two base bodies 10, 20, in which the engagement portion 21 is overlapped by the engagement projection 12.In the connected position, detachment of the second connecting part 2 from the first connecting part 1 against the magnetic forces applied by the first and second magnetic devices M1 and M2 is only possible by performing a tilting movement of the second base body 20 about the pivot axis 23 relative to the first base body 10. This detachment process is shown in the . Figure 10 illustrated in more detail.

[0084] If a user pulls with one hand H on the grip tab 30 along a pulling direction Z and pivots the second base body 20 as shown in the Figure 10By pivoting the base body 20 about the pivot axis 23 along a pivoting direction L, the two connecting parts 1 and 2 can be separated from one another. By holding the base body 20 on the flexible bridge section 34, a tensile force introduced at the grip tab 30 is again transmitted to the connecting web 204 and thus to the base body 20 only after bridging a defined play. Consequently, a displacement movement of the handle section 30 by a defined amount must first have occurred before a force is introduced into the second base body 20.

[0085] Likewise, the design of the connecting device V according to the Figures 6 to 10With the bridge section 34 and the connection of the second base body 2 thereto, it is achieved that, in the connected position of the first and second connecting parts 1, 2, the base section 31 can be displaced towards the second base body 20 when a load acts on the base section 31 (e.g., from the second assembly A2 on the base section 31). A load acting on the base section 31 when the connecting device V is closed therefore does not directly lead to a force introduction into the second base body 20 and, as a result, to a direct load on the connection between the first and second connecting parts 1, 2.In the illustrated embodiment, in the connected position, due to the design of the transmission part 3 with the bridge section 34 and the connection of the transmission part 3 to the elements of the second composite part 2, a load is always exerted on the connection between the first and second closure parts 1, 2 and thus on the closure provided thereby. In particular, the handling section in the form of the gripping tab 30 remains unloaded due to the bridge section 34.

[0086] Closing of the connecting device V is possible by means of the Figures 8A and 8Billustrated in more detail. When the second connecting part 2 is attached to the first connecting part 1, in order to connect the two assemblies A1 and A2 via the connecting device V and to hold them together, the bridge section 34 again allows the second base body 20 to snap onto the first base body 10 by a displacement movement of the second base body 20 to the possibly taut base section 31 and the gripping tab 30. Figure 9 then shows the connected position of the first and second closure parts 1 and 2. List of reference symbols
