[0001] Locking device with an adjustable connecting element

[0002] Description

[0003] The invention relates to a closure device according to the preamble of claim 1.

[0004] Such a closure device comprises a first closure part having a first body, an engagement device arranged on the first body, and a first magnetic device, and a second closure part having a second body, a connecting element movably arranged on the second body, and a second magnetic device arranged on the connecting element. To close the closure device, the first closure part and the second closure part can be placed against one another. In a closed position, the connecting element engages with the engagement device to hold the first closure part and the second closure part against one another. To open the closure device, the engagement between the connecting element and the engagement device can be released, so that the first closure part and the second closure part can be separated from one another.

[0005] In the closure device, the connecting element on the second body of the second closure part is adjustable between an initial position, in which the connecting element is at least partially received in the body, and a functional position. In the functional position, the connecting element protrudes relative to the second body, viewed along a linear direction, so that the connecting element can be brought into engagement with the engagement device of the first closure part. The first magnetic device and the second magnetic device are designed to interact in a magnetically attractive manner when the first closure part and the second closure part approach one another, in order to transfer the connecting element from the initial position along the linear direction into the functional position.

[0006] In a closure device known from DE 10 2010 044 198 A1, spring locking elements are arranged on a closure part, which, in a closed position, engage with engagement elements of another closure part. The engagement elements are accommodated in a housing of the other closure part in an initial position, so that in the initial position the engagement elements do not protrude outward from the housing or protrude only slightly. From the initial position, the engagement elements can be adjusted relative to the housing, so that in a functional position the engagement elements protrude from the housing and can be engaged with the spring locking elements to connect the closure parts.

[0007] A locking device known from US 6,659,516 for locking a laptop computer in a closed position has a hook element which is received in an initial position in an associated housing and can be pivoted out of the housing for locking.

[0008] In a locking device, such as that known from DE 10 2010 044 198 A1, engagement elements on one locking part are extended when locking parts approach each other, in order to engage with spring locking elements on another locking part in a closed position and to establish a connection between the locking parts in the closed position. The engagement elements are pre-tensioned, for example, spring-elastically, relative to a body of the associated locking part in the direction of the initial position, which results in the locking parts being in pre-tensioned contact with each other in the closed position.

[0009] For example, when using a locking device in a vehicle, for example on a padded surface, it may be desirable for locking parts in a closed position not to be in contact with one another over a large area in order to enable a reliable connection between the locking parts even on irregularly shaped, for example padded, surfaces.

[0010] It is also desirable that the connecting element does not protrude significantly from a surface when not in use, thus avoiding potential injury or impairment to users. In addition to minimizing hazards to users, there is also an aesthetic advantage when not in use, as designed surfaces in a variety of applications are not interrupted by locking elements when the locking device is not in use, yet offer the added value of an integrated locking solution when in use.

[0011] The object of the present invention is to provide a closure device which can be used variably and enables a reliable connection of closure parts.

[0012] This object is achieved by an article having the features of claim 1.

[0013] Accordingly, the engagement device has an attachment section and a receiving opening adjoining the attachment section along an insertion direction pointing transversely or obliquely to the linear direction, wherein the connecting element can be attached to the attachment section in the functional position for closing the closure device and, after being attached to the attachment section, can be pushed into the receiving opening in the insertion direction in order to transfer the closure device into the closed position.

[0014] To close the closure device, the closure parts of the closure device are brought closer together in a linear direction. Due to the magnetic interaction of the magnetic devices on the side of the first closure part and the connecting element of the second closure part, when the closure parts approach each other, the connecting element of the second closure part is moved from the starting position to the functional position. While the connecting element is fully or partially enclosed in the body of the associated second closure part in the starting position, the connecting element is adjusted relative to the body of the second closure part in the functional position such that the connecting element protrudes from the body in a linear direction and can thus be brought into engagement with the engagement device on the first closure part.

[0015] The linear direction can, for example, approximately correspond to a closing direction along which the first closure part and the second closure part can be brought closer together to close the closure device. The closure parts can, for example, be positioned against each other exclusively along the closing direction (at least along the final part of the closing path). In another embodiment, the closure parts can also be positioned against each other along the closing direction and also along other directions, for example, transversely to the closing direction, to close the closure device, so that the ability of the closure parts to approach each other is not limited to the closing direction.

[0016] The adjustment of the connecting element from the initial position to the functional position when closing the locking device is preferably carried out linearly, for example along an adjustment direction pointing along the linear direction.

[0017] The engagement device has an attachment section to which the connecting element can be attached in the functional position for closing the closure device. Adjacent to the attachment section is a receiving opening which extends from the attachment section along an insertion direction pointing transversely or obliquely to the linear direction and into which the connecting element can be inserted in the insertion direction after being attached to the attachment section in order to transfer the closure device into the closed position. The closure device is thus closed in such a way that the connecting element is first attached to the attachment section, for example along the linear direction, and is then inserted transversely or obliquely to the linear direction into the receiving opening adjoining the attachment section.In the closed position, for example, the connecting element engages positively with the receiving opening so that the locking parts are held together.

[0018] The attachment section is formed, for example, by an insertion opening into which the connecting element can be inserted in the functional position to close the closure device. However, the attachment section can also be formed by a (not further defined) surface to which the connecting element can be attached in the functional position and from which the connecting element can be inserted into the receiving opening.

[0019] Functionally, it is irrelevant whether an insertion opening forming an attachment section is circumferentially limited and defines a space into which the connecting element can be inserted. What matters is only that the connecting element, in the functional position for closing the locking device, can be attached to the attachment section and from there pushed into the receiving opening in the insertion direction.

[0020] The second closure part can, for example, be arranged on a (quasi-)stationary assembly, for example in a vehicle, for example on a vehicle seat. In the initial position, the connecting element is, for example, completely or partially accommodated in the housing of the second closure part, so that in the initial position corresponding to a non-use position, the connecting element does not protrude significantly outwards and is therefore not a hindrance and, moreover, does not impair the aesthetic external appearance of the associated assembly. The first closure part, on the other hand, can be arranged on an assembly that is to be fixed in a vehicle, for example on an electrical or electronic assembly such as a mobile phone or a navigation device or on a holding device such as a storage compartment, a coat hanger, a table or the like.When the closure parts approach each other, the connecting element is moved from the starting position into the functional position so that the closure parts can be fastened to each other and thus the first closure part is held in position on the second closure part in the closed position of the closure device.

[0021] In one embodiment, the connecting element has a head that is held positively on the engagement device in the closed position. In the closed position of the closure device, the connecting element protrudes with the head relative to the housing of the second closure part and engages the engagement device of the first closure part, so that the closure parts are fixed to one another in a positively locking manner.

[0022] The head of the connecting element can, for example, have one or more engagement projections, each forming an undercut, which engage with the engagement device in the closed position, so that the connecting element engages the engagement device in a form-fitting manner with respect to the linear direction.

[0023] In one embodiment, the second body of the second closure part forms a surface which, in the closed position, faces the first closure part, wherein the head is substantially flush with the surface in the initial position and is spaced from the surface along the linear direction in the functional position. In the initial position, the connecting element is received in the body of the second closure part such that the head does not protrude outwards, or only protrudes insignificantly, relative to the surface of the second body, but is substantially flush with the surface. The surface is not necessarily flat, but can be curved, for example, in which case the head of the connecting element can have a shape that continues the shape of the surface and is thus substantially flush with the surface.In the initial position, the second closure part thus has a self-contained shape on its outwardly facing surface, without the connecting element protruding in a disturbing manner from the body of the second closure part.

[0024] In this context, substantially flush means that no sharp-edged areas of the fastener protrude from the surface. In particular, the fastener should not protrude more than 25 mm outward relative to the surface when the fastener is in its initial position.

[0025] When the closure parts approach each other to close the closure device, the connecting element is moved from the functional position to the initial position and, in the functional position, protrudes toward the surface along the linear direction. By moving the connecting element to the functional position, it can be brought into engagement with the engagement device of the first closure part to connect the closure parts to one another in the closed position.

[0026] In one embodiment, the first magnetic device is arranged on the first body of the first closure part in the region of the attachment section, for example in the region of the insertion opening forming the attachment section, and is designed to cooperate with the second magnetic device on the connecting element of the second closure part when the first closure part and the second closure part approach one another to close the closure device in such a way that the connecting element is pulled towards the attachment section, for example into the insertion opening forming the attachment section, due to the magnetic attraction.For example, the first magnetic device can be arranged at a base of the attachment section, for example, the insertion opening forming the attachment section, so that the connecting element is magnetically drawn along the linear direction toward the attachment section through magnetic interaction with the second magnetic device on the connecting element of the second closure part. In one embodiment, the receiving opening has at least one edge section. In the closed position, the connecting element engages behind the at least one edge section, creating a positive connection between the connecting element and the engagement device, and the closure parts are secured to one another in a positive-locking manner.

[0027] In this text, a positive engagement or a positive connection is understood to mean that the locking parts are caught together with respect to the linear direction due to the shape of the engagement device on the one hand and the connecting element on the other. Thus, they cannot be separated from each other along the linear direction, at least not without breaking the positive connection. The positive connection may be subject to play. Surfaces of engaging projections that engage with each other can, for example, be beveled or curved relative to the linear direction, for example, with a spherical shape.

[0028] In one embodiment, the receiving opening has a slotted opening through which the connecting element engages in the closed position. The slotted opening can, for example, be defined between edge sections of the receiving opening, which, for example, extend approximately parallel to one another along the insertion direction or at an oblique angle to the insertion direction, resulting in a pointed slotted opening that tapers in the insertion direction. In the closed position, the connecting element engages behind the edge sections of the slotted opening with its head, for example an engagement projection formed on the head, so that a positive engagement exists between the connecting element and the engagement device.

[0029] In one embodiment, the first closure part has a locking device that is designed to act on the connecting element to block or impede movement counter to the insertion direction out of the closed position. The connecting element can be pushed into the receiving opening in the insertion direction, wherein the locking device is passed during the insertion movement. If the closure device is in the closed position, however, moving the connecting element out of the receiving opening counter to the insertion direction is made difficult or blocked by the locking device. For example, the locking device can have a locking element that is resiliently adjustable relative to the first body, past which the connecting element can be moved in the insertion direction to transfer it into the closed position, but which blocks movement of the connecting element counter to the insertion direction out of the closed position.When moving in the insertion direction, the connecting element pushes the locking element aside, allowing the locking element to be passed. Once the connecting element has passed the locking element, the locking element snaps back into a locked position due to the spring-elastic preload, preventing or hindering the connecting element's retraction from the receiving opening.

[0030] The locking element can, for example, protrude into the receiving opening in such a way that the connecting element comes into contact with the locking element when moved back against the insertion direction and thus the connecting element is locked or hindered in the receiving opening.

[0031] To make opening more difficult, the locking element can, for example, be bevelled on a stop surface facing the connecting element in the closed position along the insertion direction, so that the connecting element can run onto the stop surface counter to the insertion direction and the locking direction can thus be opened when a limit force (determined by the shape of the stop surface and the connecting element and also by a spring preload) is overcome.

[0032] In contrast, to block the opening, a stop surface of the locking element facing the connecting element in the closed position along the insertion direction can be positioned, for example, perpendicular to the insertion direction, so that the connecting element cannot run onto the stop surface and the locking device can only be opened by actuating the locking device to unlock.

[0033] In one embodiment, the locking element is tiltably mounted on the body of the first closure part. For this purpose, the locking element can be supported on the body of the first closure part via a bearing section and can thus be tiltable about the bearing section relative to the body of the first closure part. In another embodiment, the locking element can, for example, be displaceably arranged on the body of the first closure part, for example, along a linear or curved movement path.

[0034] The locking element can, for example, have a gripping portion that a user can grasp to move the locking element out of a locked position and thus unlock the locking device. By moving the locking element relative to the body of the first locking part, the locking element can be moved out of the region of the receiving opening such that the connecting element can be moved counter to the insertion direction in the receiving opening and brought into the region of the attachment portion, so that the second locking part can be removed from the first locking part.

[0035] In one embodiment, the first closure part has an actuating element that can be actuated by a user to move the locking device out of a locked position. The actuating element is preferably designed as an additional element to the locking element of the locking device.

[0036] In one embodiment, the actuating element is adjustable relative to the body of the first closure part. The actuating element can, in principle, be movable in any desired manner relative to the body of the first closure part, for example, pivotable, rotatable, or displaceable.

[0037] For example, the actuating element can be linearly displaceable on the body. By displacing the actuating element on the body of the first closure part, the actuating element acts on the locking element of the locking device and moves the locking element out of the locked position, so that the closure device is unlocked and the second closure part can thus be moved out of the area of ​​the receiving opening.

[0038] In one embodiment, the actuating element is movable along an actuating direction on the body—for example, longitudinally, transversely, or obliquely relative to the insertion direction. The actuating element can be designed, for example, as a push-button element that can be moved, for example, longitudinally, obliquely, or transversely to the insertion direction, thereby acting on the locking element and displacing the locking element out of the region of the receiving opening such that the connecting element of the second closure part can be released and moved out of the receiving opening counter to the insertion direction.

[0039] In one embodiment, the actuating element has a first active element. The locking device, in contrast, has a second active element. The first active element is designed to deflect the force on the second active element when the actuating element is adjusted along the actuating direction to move the locking device in a direction different from the actuating direction. For example, a bevel is formed on each of the active elements. When the actuating element is actuated, the active elements converge on one another, so that the locking element is adjusted, for example, transversely to the actuating direction on the body of the first closure part.

[0040] Essentially, the actuating element moves the locking device. The force can be transmitted by force redirection, with the actuating element's direction of movement being different from the locking device's direction of movement. However, the actuating element can also be designed to drive the locking device along with it, with the actuating element's direction of movement being the same as the locking device's direction of movement.

[0041] For example, by moving the actuating element along the actuating direction, the locking element of the locking device on the body of the first closure part can be tilted, so that the locking element is moved out of the area of ​​the receiving opening and the connecting element is thus unlocked.

[0042] In one embodiment, the connecting element has a positive-locking section that, in the closed position, engages rotationally with the first closure part. In the closed position, not only are the closure parts held together, but the connecting element is also fixed in its position relative to the body of the second closure part. For this purpose, the connecting element engages with the first closure part via the positive-locking section in the closed position, so that any rotational movement of the connecting element relative to the first closure part is blocked in the closed position.

[0043] For example, the form-locking section can be rotationally engaged with the engagement device in the closed position. For example, a head of the connecting element can have a rotationally symmetrical shape (with respect to a rotational axis extending along the linear direction) and, for example, form an engagement projection that extends around the rotational axis and projects radially outward. In contrast, the form-locking section can deviate from a rotationally symmetrical shape, for example, so that engagement with the engagement device can result in a rotationally fixed attachment of the connecting element to the engagement device.

[0044] For example, in the closed position, the form-locking section can be located between edge sections of the engagement device, for example between edge sections of a slot opening of a receiving opening of the engagement device. The form-locking section can, for example, be flattened, viewed along a plane perpendicular to the rotation axis, and form mutually opposite, parallel, flat wall sections with which the form-locking section bears against the edge sections of the engagement device in the closed position. Due to the position of the form-locking section between the edge sections of the engagement device, the form-locking section, and above it the connecting element, are rotationally fixed in the closed position.

[0045] It should be noted that the form-fitting section can also engage positively with other counter-sections on the side of the first closure part in order to fix the connecting element in a rotationally fixed manner relative to the first closure part.

[0046] In particular, the functions can also be separated: For example, the engagement device can only fix the connection along a linear direction, but still allow rotation of the connecting element. The rotation lock can then be achieved separately via one or more other design elements.

[0047] In one embodiment, the connecting element is guided linearly along an adjustment direction on the second body. The connecting element is thus adjustable linearly, i.e., in a straight line, relative to the body of the second closure part. The adjustment direction can be directed, for example, along the linear direction or transversely or obliquely thereto.

[0048] In one embodiment, the connecting element is rotatable relative to the second body about the adjustment direction. The connecting element is guided on the body of the second closure part in such a way that the connecting element can adjust linearly on its adjustment path, but cannot rotate about the adjustment direction relative to the body of the second adjustment part. In one embodiment, the second closure part has an elastically deformable prestressing element that is designed to prestress the connecting element relative to the second body, at least in the functional position. The prestressing element can be formed, for example, by an elastic spring or by a rubber element, for example an O-ring, which extends about an axis of rotation assigned to the connecting element.When transferred into the functional position, the pre-tensioning element is elastically tensioned so that in the functional position an elastic pre-tension is exerted on the connecting element relative to the body of the second closure part.

[0049] In one embodiment, the connecting element is held in the initial position relative to the second body when the closure device is in the open position. For example, the connecting element can be spring-loaded or magnetically preloaded relative to the body of the second closure part toward the initial position.

[0050] In one embodiment, the second closure part has a third magnetic device arranged on the second body of the second closure part, which magnetically interacts with the second magnetic device to hold the connecting element in the initial position. The third magnetic device interacts with the second magnetic device in a magnetically attractive manner, so that when the closure device is open, the connecting element is held in the initial position on the body of the second closure part.If the closure parts are brought closer together, the magnetic attraction between the first magnetic device of the first closure part and the second magnetic device on the connecting element of the second closure part superimposes the magnetic attraction between the second magnetic device and the third magnetic device and exceeds this as soon as the closure parts have been brought sufficiently close to one another, so that the connecting element is transferred from the starting position into the functional position due to the magnetic attraction between the first magnetic device and the second magnetic device.

[0051] In one embodiment, the first closure part and the second closure part are fixed to one another in the closed position, viewed along the linear direction and along a plane perpendicular to the linear direction. In the closed position, the first closure part and the second closure part cannot be moved relative to one another, in particular not even rotationally. The fixed position, in particular in a plane perpendicular to the linear direction, in particular rotationally about the linear direction, can be achieved, for example, by a suitable engagement structure on the first closure part and the second closure part. Along the linear direction, in contrast, the closure parts are fixed to one another via the engagement of the connecting element in the engagement device.

[0052] In one embodiment, the second closure part has two connecting elements, each of which is adjustable between an initial position and a functional position relative to the second body and, in the functional position, as viewed along the linear direction, protrudes relative to the second body such that the connecting elements can be brought into engagement with the engagement device of the first closure part. In the closed position, the connecting elements each engage with the engagement device to hold the first closure part and the second closure part against one another. The connecting elements each have an associated second magnetic device for magnetically interacting with the first magnetic device of the first closure part.

[0053] For example, two engagement openings and two adjoining receiving openings can be formed on the engagement device, wherein one attachment section, for example one insertion opening each, and one receiving opening are assigned to one of the connecting elements.

[0054] Because the connection between the closure parts in the closed position is established via two connecting elements and their engagement with the engagement device of the first closure part, the closure parts are fixed in a positionally fixed manner, in particular also rotationally fixed, to one another in the closed position and thus establish a positionally fixed connection between assemblies that are assigned to the closure parts.

[0055] In one embodiment, the first closure part has a first electrical contact assembly and the second closure part has a second electrical contact assembly. When the closure device is closed, the contact assemblies, which can each have one or more electrical contacts, for example, come into electrical contact with one another, thus establishing an electrical connection. The first electrical contact assembly can be formed, for example, by a first electrical connector part and the second electrical contact assembly by a second electrical connector part. When the closure device is closed, the connector parts engage with one another in a plug-in manner. The first electrical connector part and the second electrical connector part are connected to one another in a plug-in manner in the closed position.A plug-in direction along which the plug-in connection is to be established preferably corresponds to the insertion direction.

[0056] The connector parts can be used, for example, to establish a data connection or an electrical supply connection between assemblies associated with the closure parts. The connector parts can be configured, for example, as USB ports, such as USB-C ports, or other ports for electrical or electronic devices, such as for telecommunications applications.

[0057] In one embodiment, the second connector part is arranged on the connecting element of the second closure part. For example, the first connector part can be arranged in the region of the receiving opening of the engagement device of the first closure part. When the connecting element is brought into engagement with the engagement device upon closing the closure device, the connector parts are connected to one another in a plug-in manner, thus establishing not only the mechanical fastening of the closure parts to one another but also an electrical connection.

[0058] The closure device is designed to be magnetic. The first magnetic device and the second magnetic device can, for example, each be formed by a permanent magnet that faces each other with opposite poles and thus magnetically attracts each other. In another embodiment, the first magnetic device and the second magnetic device can be formed, on the one hand, by a permanent magnet and, on the other hand, by a passive magnetic armature, for example, made of a ferromagnetic material.

[0059] If the second magnetic device is formed by a permanent magnet, the third magnetic device can be formed, for example, by a passive magnetic armature. In another embodiment, the third magnetic device is formed by a permanent magnet that is magnetically attractive to the second magnetic device. One or more of the magnetic devices can also be formed by electromagnets, for example.

[0137] Fig. 15 is a schematic representation of an embodiment of a first closure part of a closure device.

[0138] In an embodiment shown in Fig. 1A-1C to Fig. 6A-6I, a closure device 1 has a first closure part 2 and a second closure part 3 to be connected to the first closure part 2 along a linear direction corresponding to the closing direction X. The closure parts 2, 3 are separated from one another in an open position, shown in Fig. 3A to 3I. In a closed position, shown in Fig. 6A to 6I, the closure parts 2, 3 are fastened to one another, so that assemblies assigned to the closure parts 2, 3 are connected to one another via the closure device 1. The closure part 2 has a body 20 on which an engagement device 21 is formed. The engagement device 21 has, as can be seen, for example, from the exploded view according to Fig. 1B and the separate view of the closure part 2 according to Fig.2, an insertion opening 210 forming an attachment section, to which an associated receiving opening 211 adjoins along an insertion direction Y.

[0139] A magnetic device 22 is arranged on the body 20 in the region of the insertion opening 210 forming the attachment section. In the illustrated embodiment, the magnetic device 22 is designed as a permanent magnet and is received in an opening 200 on the body 20, as can be seen from the exploded view according to Fig. 1A.

[0140] The closure part 3 has a connecting element 34 which is guided on a body 30 of the closure part 3 so as to be linearly adjustable along an adjustment direction corresponding to the closing direction X.

[0141] The connecting element 34 has a magnetic device 32 in the form of a permanent magnet, which interacts in a magnetically attractive manner with the magnetic device 22 on the body 20 of the closure part 2. As can be seen from the sectional view according to Fig. 3I in conjunction with Fig. 1A, the magnetic device 32 is arranged in the region of a head 343 of the connecting element 34.

[0142] The connecting element 34 has an adjusting body 340 on which the head 343 is formed. The head 343 forms two engagement projections pointing away from each other along a transverse direction Q for engaging the engagement device 21 of the closure part 2. Between the head 343 and a base plate of the adjusting body 340, a form-fitting section 344 with flattened side surfaces facing away from each other along the transverse direction Q is formed.

[0143] With the adjusting body 340, the connecting element 34 is received in the body 30 and guided adjustably along the closing direction X.

[0144] The body 30 is delimited on a side facing away from the surface 300 of the body 30 by a base element 35, on which a third magnetic device 36 in the form of a permanent magnet or a passive magnetic armature is received. The base element 35 has a base plate 350 that delimits the body 30 to the rear of the surface 300. A prestressing element 33 in the form of a rubber-elastic O-ring is accommodated inside the body 30, which serves to prestress the connecting element 34 relative to the body 30.

[0145] In the open position of the closure device 1, shown in Figs. 3A to 3I, the closure parts 2, 3 are separated from one another. The connecting element 34 is in an initial position shown in Figs. 3A to 3I, in which the head 343 of the connecting element 34 is arranged within an opening 302 on the surface 300 and is substantially flush with the surface 300 of the body 30 and thus does not protrude outwardly. In the initial position, the connecting element 34 is thus received inside the body 30 and thus countersunk relative to the body 30 of the closure part 3.

[0146] In the initial position when the closure device 1 is open, the magnetic device 32 of the connecting part 34 interacts with the magnetic device 36 on the base element 35 and thereby magnetically holds the connecting element 34 in the initial position.

[0147] Because the connecting element 34 does not protrude outwards from the body 30 in the initial position, the connecting element 34 is not obstructive when the closure device 1 is open and also does not disturb an aesthetic impression, for example in the interior of a vehicle (for example when the closure part 3 is fixed to an associated assembly, for example to a vehicle seat, in order to enable an assembly associated with the closure part 2 to be fastened to the vehicle assembly associated with the closure part 3 by connecting it to the closure part 2).

[0148] If the closure parts 2, 3 are brought (approximately) closer to one another along the closing direction X, the closure parts 2, 3 are brought into a position relative to one another due to the magnetic attraction forces between the magnetic device 22 on the closure part 2 and the magnetic device 32 on the closure part 3, in which the connecting element 34 is opposite the insertion opening 210 of the engagement device 21 and is aligned with the insertion opening 210 along the closing direction X, as can be seen from the sectional view according to Fig. 3I.

[0149] If the closure parts 2, 3 are brought close to one another along the closing direction X to such an extent that the magnetic attractive forces between the magnetic device 22 on the closure part 2 and the magnetic device 32 on the closure part 3 exceed the magnetic holding forces between the magnetic devices 32, 36 on the closure part 3, the connecting element 34 is moved from the starting position according to Fig. 3A to 3I towards a functional position relative to the body 30 of the closure part 3, as can be seen from Fig. 4A to 4I. The connecting element 34 is thus adjusted on the body 30 and thereby extended out of the body 30 through the opening 302 in the surface 300, so that the connecting element 34 protrudes with its head 343 relative to the surface 300 of the body 30.

[0150] In the illustrated embodiment, the connecting element 34 is guided linearly along the closing direction X on the body 30 of the closure part 3 and is mounted so as to be rotationally fixed to the body 30. In the starting position according to Fig. 3A to 3I, the connecting element 34 lies with the head 343 in the opening 302 on the surface 300 of the body 30. When the connecting element 34 is adjusted to move it from the starting position to the functional position, the connecting element 34 is moved outwards through the opening 302 in the surface 300, wherein due to the cross-sectional shape of the head 343, the connecting element 34 reaches through the opening 302 such that the connecting element 34 is rotationally fixed to the body 30 of the closure part 3.

[0151] In the position according to Fig. 4A to 4I, the connecting element 34 is in contact with a bottom 214 of the insertion opening 210 with its head 343 and is located opposite the magnetic device 22 on the body 20 of the closure part 2, as can be seen from Fig. 4I.

[0152] To completely close the closure device 1, the closure parts 2, 3 are now displaced relative to one another along the insertion direction Y, which extends transversely to the closing direction X, so that the connecting element 34 runs into the receiving opening 211 along the insertion direction Y, as can be seen from Fig. 5A to 5I. The connecting element 34 thus engages with the receiving opening 211 in such a way that the connecting element 34, with the head 343 and the outwardly projecting engagement projections formed thereon, engages behind edge sections 212 of the receiving opening 211 and the form-fitting section 344 axially adjoining the head 343 engages between the edge sections 212, as can be seen in the transition from Fig. 5A to 5I to Fig. 6A to 6I.In the illustrated embodiment, the connecting element 34 is inserted into the receiving opening 211 manually by a user, whereby the insertion can be assisted, for example, by gravity.

[0153] When inserted into the receiving opening 211, the magnetic device 22 on the closure part 2 and the magnetic device 32 on the connecting element 34 on the closure part 3 are tangentially moved away from each other along the insertion direction Y, so that the insertion takes place against the magnetic attraction force of the magnetic devices 22, 32.

[0154] A locking device 24 is arranged on the body 20 of the closure part 2. The locking device 24 has a locking element 240 that is tiltably mounted on the body 20 via a bearing section 243 and can be tilted relative to the body 20 about a tilt axis extending transversely to the closing direction X and transversely to the insertion direction Y and pointing along the transverse direction Q. The locking element 240 is spring-loaded relative to the body 20 via a spring element 242. The body 20 is closed at a rear side by a housing part 202. A bearing receptacle 203 is formed on the housing part 202, on which the bearing section 243 of the locking element 240 is received for tiltable mounting.

[0155] The locking element 240 engages with a locking lug 241 through an opening 215 in the base 214 of the engagement device 21 into the area of ​​the receiving opening 211 (see Fig. 2 in conjunction with the sectional view according to Fig. 3F), so that the connecting element 34 with its head 343 slides onto the locking lug 241 when inserted into the receiving opening 211, pushes it aside and thus passes the locking element 240, as can be seen in the transition from Fig. 5A-5I to Fig. 6A-6I.

[0156] In the closed position shown in Fig. 6A to 6I, the closure device 1 is thus locked in that the connecting element 34 is blocked by the locking device 24 in the receiving opening 211 or can only slide out of the receiving opening 211 with difficulty against the insertion direction Y.

[0157] As can be seen from Fig. 4A-4I and 5A-5I, the prestressing element 33 of the connecting element 34 assumes an intermediate position between the base plate of the adjusting body 340 of the connecting element 34 and the body 30 during the magnetically effected adjustment of the connecting element 34 from the initial position towards the functional position and is elastically tensioned so that a prestress is provided for the play-free and rattling-free connection of the closure parts 2, 3.

[0158] Because the connecting element 34 engages with the positive-locking portion 344 in a positive-locking manner between the edge portions 212 of the receiving opening 211 when the closure device 1 is in the closed position according to Figs. 6A to 6I, the connecting element 34 is locked in its rotational position relative to the body 20 of the closure part 2. Because the connecting element 34 is also guided in a rotationally fixed manner on the body 30 of the closure part 3, the closure parts 2, 3 are fixed in position in the closed position, in particular rotationally fixed (with respect to the closing direction X) relative to one another.

[0159] If the closure device 1 is to be opened again, a user can, for example, act manually on the locking device 24 via a handle section 244 projecting outwards from the body 20 and tilt the locking element 240 towards the body 20 in such a way that the locking lug 241 is removed from the area of ​​the receiving opening 211 through the opening 215 and thus the connecting element 34 is pushed out of the receiving opening 211 along the insertion direction Y and the closure device 1 can thus be opened.

[0160] In the illustrated embodiment, an electrical connector part 23 is arranged on the body 20 of the closure part 2, which is located at one end of the receiving opening 211. An associated mating connector part 37 is arranged on the adjusting body 340 of the connecting element 34. When the connecting element 34 engages in the receiving opening 211, the mating connector part 37 assumes a position opposite the connector part 23, so that when the connecting element 34 is inserted along the insertion direction Y into the receiving opening 211, the connector parts 23, 37 engage with one another in a plug-in manner, thus establishing an electrical connection between the connector parts 23, 37.

[0161] The connector parts 23, 37 can, for example, form an electrical connector via which data signals can be transmitted and / or an electrical supply can be provided. For example, such a connector can implement a USB connector, for example a USB-C connector. An embodiment illustrated in Figs. 7A-7C to 14A-14H is identical to the embodiment previously explained with reference to Figs. 1A-1C to 6A-6I, except for the differences explained below.

[0162] In contrast to the embodiment according to Figs. 1A-1C to 6A-6I, in the embodiment according to Figs. 7A-7C to 14A-14H, no gripping portion is formed on the locking element 240 of the locking device 24 that can be actuated by a user from outside the body 20. Instead, an actuating element 25 is arranged on the body 20 of the first closure part 2, displaceable along an actuating direction B, which is designed to unlock the locking device 24.

[0163] The actuating element 25 has a sliding body 250 that extends longitudinally along the actuating direction B and projects through an opening 204 in the body 20 of the first closure part 2. At an outwardly projecting end, the sliding body 250 carries an actuating portion 251 that can be actuated by a user from outside the body 20.

[0164] The actuating element 25 is spring-loaded along the actuating direction B by a preloading element 253 in the form of a mechanical compression spring relative to the body 20.

[0165] In the illustrated embodiment, the actuation direction B is directed transversely to the insertion direction Y.

[0166] On the sliding body 250 of the actuating element 25, active elements 252 are formed which are designed to interact with active elements 245 on the locking element 240 of the locking device 24.

[0167] In a non-actuated position, which the actuating element 25 assumes when no user presses on the actuating section 251, the actuating element 25 projects outwardly with the actuating section 251 opposite to the actuating direction B, as can be seen from Figs. 8A-8H to 11A-11H. In the direction of this non-actuated position, the actuating element 25 is prestressed via the prestressing element 253.

[0168] The closing of the closure device 1 takes place in the same way as was explained above for the embodiment according to Fig. 1A-1C to 6A-6I and as can be seen from the transition from the open position (Fig. 8A-8H) to the closed position (Fig. 11A-11H).

[0169] In the closed position according to Fig. 11 A-11 H, the connecting element 34 of the second closure part 3 is locked in the receiving opening 211 of the engagement device 21 of the first closure part 2, in that the locking device 24 with locking lugs 241 formed on the locking element 240 projects into the region of the receiving opening 211 and thus locks the head 343 of the connecting element 34 in the receiving opening 211, as can be seen from Fig. 11 H. In particular, the locking lugs 241 protrude from the bottom 214 of the engagement device 21 in the locked position according to Fig. 11 H and come to lie behind the head 343 of the connecting element 34, so that the connecting element 34 cannot (easily) be moved out of the receiving opening 211 against the insertion direction Y.

[0170] To unlock the locking device 1, a user can press on the actuating portion 251 in the actuating direction B and thereby displace the actuating element 25 on the body 20 of the first locking part 2, as can be seen in Figs. 12A-12H. As a result, the active elements 252 on the displacement body 250 run onto the active elements 245 on the locking element 240 and tilt the locking element 240 on the body 20 of the first locking part 2. The locking lugs 241 are thus moved out of the region of the receiving opening 211, so that the connecting element 34 is released in the receiving opening 211.

[0171] The connecting element 34 can thus be displaced counter to the insertion direction Y in the receiving opening 211, as can be seen from Fig. 13A-13H and 14A-14H, so that the closure parts 2, 3 can be removed from each other from the position shown in Fig. 14A-14H and the closure device 1 is thus opened.

[0172] Apart from the actuation of the locking device 24 via the actuating element 25, the embodiment according to Figs. 7A-7C to 14A-14H is identical to the embodiment described above with reference to Figs. 1A-1C to 6A-6I, so that reference should also be made in full to the explanations therein.

[0173] In the exemplary embodiments described above and illustrated in the figures, the attachment section 210 is formed by a circumferentially limited insertion opening into which the connecting element 34 of the closure part 3 can be inserted in the functional position in order to close the closure device 1. However, it is not functionally decisive whether the attachment section 210 is circumferentially limited. What is important is merely that the connecting element 34 can be attached to the attachment section 210 to close the closure device 1, in order to be inserted from there into the receiving opening 211 adjoining the attachment section 210.

[0174] In an embodiment of a first closure part 2 shown schematically in Fig. 15, the attachment section 210 is formed by a surface to which the connecting element 34 can be attached and from there inserted along the insertion direction Y into the adjoining receiving opening 211.

[0175] For example, a magnetic device 22 for interacting with the connecting element 34 of the closure part 3 can be arranged in the region of the attachment section 210 formed by the surface.

[0176] Apart from the design of the attachment section 210, the embodiment according to Fig. 15 is identical to the previously described embodiment. In particular, the closure part 2 according to Fig. 15 can be used with the closure part 3 of the previously described embodiments.

[0177] The idea underlying the invention is not limited to the embodiments described above, but can also be implemented in other ways.

[0178] A locking device of the type described can be used, for example, in a vehicle, for example to fasten objects, such as electrical or electronic devices or holders for these devices, to a vehicle seat or to another vehicle component.

[0179] However, this is not limiting. A locking device of the type described can be used to connect any number of assemblies together. Reference numerals
