LOCKING DEVICE WITH AN ADJUSTABLE CONNECTING ELEMENT

Description

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

[0002] Such a locking device comprises a first locking part, which has a first body, an engagement device arranged on the first body, and a first magnetic device, and a second locking part, which has 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 locking device, the first locking part and the second locking part are brought into contact with each other. In a closed position, the connecting element engages with the engagement device to hold the first locking part and the second locking part together. To open the locking device, the engagement between the connecting element and the engagement device can be released, so that the first locking part and the second locking part can be separated from each other.

[0003] In the locking device, the connecting element on the second body of the second locking part is adjustable along a path between a starting position, in which the connecting element is at least partially enclosed in the body, and a functional position. In the functional position, viewed along a linear direction, it projects relative to the second body, allowing the connecting element to engage with the engagement mechanism of the first locking part. The first and second magnetic devices are designed to attract each other magnetically when the first and second locking parts approach each other, thereby moving the connecting element from its starting position to its functional position.

[0004] In a locking device known from DE 10 2010 044 198 A1, spring-loaded locking elements are arranged on a locking part, which, in a closed position, engage with engagement elements of another locking part. In a starting position, the engagement elements are received in a housing of the other locking part, such that in the starting position, the engagement elements do not protrude from the housing or only protrude minimally. From the starting 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 brought into engagement with the spring-loaded locking elements to connect the locking parts.

[0005] 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 associated housing in a starting position and can be swung out of the housing to lock it.

[0006] In a locking device, such as that known from DE 10 2010 044 198 A1, engagement elements are extended on one locking element as the locking parts approach each other. In the closed position, these elements engage with spring-loaded locking elements on another locking part, thus establishing a connection between the locking parts. The engagement elements are pre-tensioned relative to a body of the associated locking part in the direction of the initial position, for example, by a spring force. This results in the locking parts being in a pre-tensioned position against each other in the closed position.

[0007] For example, when using a locking device in a vehicle, such as on a padded surface, it may be desirable that locking parts do not have a large contact area with each other in a closed position, in order to enable a reliable connection between the locking parts even on irregularly shaped surfaces, such as padded surfaces.

[0008] The object of the present invention is to provide a closure device that is variably applicable and enables a reliable connection of closure parts, even, for example, on irregularly shaped surfaces.

[0009] This problem is solved by an object having the features of claim 1.

[0010] Accordingly, the connecting element for transferring from the initial position to the functional position is movable at least along part of the adjustment path along an adjustment direction different from the linear direction relative to the second body, whereby in the closed position, due to the engagement of the connecting element with the engagement device, movement of the connecting element along the adjustment direction relative to the second body is blocked.

[0011] To close the locking device, the locking components are brought close together, for example, along a closing direction. Due to the magnetic interaction of the magnetic elements on the first locking component and the connecting element of the second locking component, the connecting element of the second locking component is moved from its initial position to its operating position as the locking components approach each other. While in the initial position the connecting element is wholly or partially embedded in the body of the associated second locking component, in the operating position the connecting element is adjusted relative to the body of the second locking component such that it protrudes from the body along a linear direction and can thus engage with the engagement mechanism on the first locking component.

[0012] The linear direction can, for example, approximate a closing direction along which the first locking part and the second locking part can be brought close to each other to close the locking device.

[0013] The locking components can, for example, be attached to each other exclusively along the closing direction (at least on the final part of the closing path). In another configuration, however, the locking components can also be attached to each other along the closing direction and also along other directions, for example, perpendicular to the closing direction, in order to close the locking device, so that the approach of the locking components to each other is not limited to the closing direction.

[0014] However, the adjustment of the connecting element from the initial position to the functional position when closing the locking device does not (exclusively) occur linearly along the linear direction, but at least over part of the adjustment path in a guided manner along an adjustment direction different from the linear direction.The adjustment movement of the connecting element for transitioning from its initial position to its functional position when closing the locking device includes, for example, superimposed motion components. These components involve adjustments occurring along a linear direction on the one hand, and along a direction perpendicular to the linear direction or rotating around the linear direction on the other. As the locking parts approach each other, the connecting element is adjusted relative to the body of the second locking part such that, in its functional position, it protrudes along the linear direction relative to the body. Thus, the movement of the connecting element is not purely linear. Rather, it moves in a guided manner along a path of motion that deviates from the linear direction.

[0015] The connecting element can be adjustable in a straight line on the body of the second locking part. In this case, the adjustment direction is preferably perpendicular or oblique to the linear direction, so that one direction vector component points, for example, along the linear direction and another direction vector component of the movement points perpendicular to the linear direction.

[0016] In another embodiment, the connecting element to the body of the second closure part is rotatably guided, in which case one direction vector component of the rotational movement points along the linear direction and another direction vector component points rotationally around the direction of rotation.

[0017] Other, superimposed movements can also occur. For example, the connecting element may initially be moved linearly along the linear direction to transition from the initial position to the functional position, with a movement occurring along a different direction than the linear direction on part of the adjustment path, for example, on the last part of the adjustment path before reaching the functional position, such as along a helical path directed around the linear direction.

[0018] The phrase "the adjustment direction differs from the linear direction" here means that the adjustment direction deviates from the linear direction with a direction vector component, at least over part of the adjustment path. This direction vector component, deviating from the linear direction, is in particular perpendicular to the linear direction or extends in a plane perpendicular to the linear direction, for example, in the case of a rotational movement around the linear direction. However, a direction vector component of the adjustment direction preferably points in the linear direction, so that, due to the adjustment movement in the adjustment direction, the connecting element is moved from the initial position to the functional position in a guided manner and, in the functional position, protrudes relative to the body of the second locking element when viewed along the linear direction.

[0019] The adjustability of the connecting element along the adjustment direction, which differs from the linear direction, can be used to lock the connecting element in its position relative to the body of the second locking part when the locking device is in the closed position. Thus, in the closed position, due to the engagement of the connecting element with the engagement mechanism, movement of the connecting element along the adjustment direction relative to the second body of the second locking part is blocked. Because of this locking effect, the connecting element cannot move along the adjustment direction relative to the body of the second locking part when the locking device is in the closed position and the connecting element is engaged with the engagement mechanism of the first locking part.Because movement along the adjustment direction is blocked, the connecting element is fixed in its functional position relative to the body of the second locking part, preventing it from being moved out of this position. This ensures that, in the closed position, the connecting element engages with the engagement mechanism of the first locking part, thereby establishing the connection between the two parts, while the body of the second locking part is not necessarily in contact with the body of the first. By locking the connecting element in its functional position when the locking device is in the closed position, the bodies of the locking parts are kept at a distance from each other, thus preventing them from being in direct contact.

[0020] This makes it possible, in particular, to create a secure and reliable connection between the fastener components, even on irregularly shaped surfaces, such as padded surfaces, regardless of the shape of the fastener bodies. Furthermore, signs of wear, such as scratches or scuffs, on a padded surface can be avoided in this way.

[0021] The second locking element can, for example, be arranged on a (quasi-)stationary assembly, such as in a vehicle, for instance, on a vehicle seat. In its initial position, the connecting element is, for example, wholly or partially enclosed within the housing of the second locking element, so that in the non-use position, the connecting element does not protrude and is therefore not obstructive, and also does not detract from the aesthetic appearance of the associated assembly. The first locking element, on the other hand, can be arranged on an assembly that is fixed in place, for example, in a vehicle, such as an electrical or electronic assembly like a mobile phone or a navigation device, or on a mounting device like a storage compartment, a clothes hanger, a table, or the like.As the locking parts approach each other, the connecting element is moved from the initial position to the functional position, so that the locking parts can be attached to each other and thus the first locking part is held in position on the second locking part in the closed position of the locking device.

[0022] In one embodiment, the connecting element has a head that is positively locked to the engagement device in the closed position. In the closed position of the locking device, the connecting element with its head projects relative to the housing of the second locking part and engages in the engagement device of the first locking part, so that the locking parts are positively locked to each other.

[0023] The head of the connecting element can, for example, have an engagement projection forming an undercut, which engages 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.

[0024] In one embodiment, the second body of the second locking part forms a surface that, in the closed position, faces the first locking part. In the initial position, the head is essentially flush with the surface, while in the functional position, it is spaced from the surface along the linear direction. In the initial position, the connecting element is received in the body of the second locking part such that the head does not protrude outwards relative to the surface of the second body, or only does so minimally, but is essentially flush with the surface. The surface is not necessarily flat, but can, for example, be curved. In this case, the head of the connecting element can have a shape that continues the contour of the surface and is thus flush with it.In its initial position, the second locking part thus has a closed shape on its outwardly facing surface, without the connecting element protruding disruptively from the body of the second locking part.

[0025] The term "essentially flush" in this context means that no sharp edges of the fastener protrude from the surface. In particular, the fastener should not protrude more than 25 mm outwards relative to the surface when in its initial position.

[0026] As the locking parts approach each other to close the locking device, the connecting element is moved from its functional position to its initial position and, in the functional position, protrudes from the surface along the linear direction. This movement allows the connecting element to engage with the engagement mechanism of the first locking part, thus connecting the locking parts together in the closed position.

[0027] In one embodiment, the surface of the second body is not in contact with the first body when closed. Because the connecting element is locked in its position relative to the body of the second locking part when the locking device is in the closed position, the bodies of the locking parts can be kept apart from each other in the closed position. This ensures that, in particular, the surface of the second locking part is not in contact with the body of the first locking part. The connection of the locking parts thus becomes independent of the properties of the locking parts' bodies, especially their surface finish, such as padding on one of the locking parts.

[0028] The engagement mechanism of the first locking part can be designed in different ways.

[0029] For example, the engagement device can be designed to create a latching connection with the connecting element in the closed position. For this purpose, the engagement device can, for example, include a spring locking element, as described in DE 10 2010 044 198 A1. When the locking device is closed, the connecting element thus engages with the engagement device in a latching manner and is preferably positively locked to the engagement device in the closed position.

[0030] In one embodiment, the engagement device has an insertion opening into which the connecting element can be inserted in the functional position for closing the locking device.

[0031] It can be provided that the first magnetic device is arranged on the first body of the first locking part in the area of ​​the insertion opening and is configured to interact with the second magnetic device on the connecting element of the second locking part when the first locking part and the second locking part approach each other to close the locking device, such that the connecting element is drawn into the insertion opening due to magnetic attraction. For example, the first magnetic device can be arranged on the bottom of the insertion opening so that, through magnetic interaction with the second magnetic device on the connecting element of the second locking part, the connecting element is moved into the insertion opening along a linear direction and is thus magnetically drawn into the insertion opening.

[0032] An insertion opening can be connected to, for example, a receiving opening that extends from the insertion opening along an insertion direction perpendicular to the linear direction. After being inserted into the insertion opening, the connecting element can be inserted into this receiving opening in the insertion direction to bring the locking device into the closed position. The locking device is thus closed by first inserting the connecting element into the insertion opening along the linear direction and then inserting it perpendicular to the linear direction into the receiving opening adjacent to the insertion opening. In the closed position, the connecting element engages with the receiving opening in a form-fitting manner, for example, so that the locking parts are held together.

[0033] For example, the receiving opening has at least one edge section. In the closed position, the connecting element engages behind this at least one edge section, creating a positive connection between the connecting element and the engagement device, and thus positively locking the locking parts to each other.

[0034] In this text, a positive locking engagement or positive locking connection means that the locking parts are locked together in the linear direction due to the shape of the engagement device on the one hand and the connecting element on the other, and therefore cannot be separated from each other along the linear direction, at least not without breaking the positive locking. The positive locking connection may have some play. The surfaces of engagement projections that are in contact with each other may also be chamfered or curved in the linear direction, for example, convexly shaped.

[0035] In one embodiment, the first locking element can have one or more wedge surfaces formed against which the connecting element runs when it is inserted into the receiving opening in the insertion direction. Such a wedge surface allows the connecting element to be axially fixed to the engagement device without play along the linear direction (both in and out of the linear direction).

[0036] The keel surface can, for example, be shaped at least on one edge section.

[0037] A first wedge surface can, for example, be formed on a side of the edge section facing outwards towards the second locking part, while a second wedge surface can be formed on a side of the edge section facing inwards away from the second locking part. The connecting element is designed so that, when inserted into the receiving opening, both wedge surfaces interact to axially secure it by wedging.

[0038] In one embodiment, the receiving opening has a slot through which the connecting element engages in the closed position. The slot can be defined, for example, between edge sections of the receiving opening, which extend approximately parallel to each other along the insertion direction, or at an oblique angle to the insertion direction, resulting in a tapered slot that narrows towards the insertion direction. In the closed position, the connecting element engages behind the edge sections of the slot with its head, for example, a forming engagement projection on the head, thus creating a positive-locking engagement between the connecting elements and the engagement device.

[0039] In one embodiment, the first locking element has a locking device designed to lock the connecting element from the closed position, preventing movement against the insertion direction. The connecting element can be inserted into the receiving opening in the insertion direction, passing the locking device during the insertion movement. However, when the locking device is in the closed position, the locking device makes it difficult or impossible to move the connecting element out of the receiving opening against the insertion direction.

[0040] For example, the locking device can have a spring-loaded locking element that is adjustable relative to the first body. The connecting element can be moved past this locking element in the insertion direction to move it into the closed position, but it prevents the connecting element from moving out of the closed position in the opposite direction. When moving in the insertion direction, the connecting element pushes the locking element aside, allowing it to pass through. Once the connecting element has passed the locking element, the spring-loaded preload causes the locking element to snap back into a locked position, thus preventing or hindering the connecting element from moving back out of the receiving opening.

[0041] The locking element can, for example, protrude into the receiving opening in such a way that, when the connecting element is moved back against the insertion direction, it comes into contact with the locking element, thus blocking or at least hindering the connecting element in the receiving opening.

[0042] To make opening more difficult, the locking element can, for example, be beveled 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 against 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.

[0043] To prevent opening, a stop surface of the locking element facing the connecting element in the closed position along the insertion direction can, for example, be positioned 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 it.

[0044] In one embodiment, the connecting element is guided on the second body, at least along part of its adjustment path, such that it can be rotated relative to the second body about an axis of rotation pointing along the v-direction, and is movable along the linear direction due to this rotation. Thus, at least along part of its adjustment path when moving from the initial position to the functional position, the connecting element performs an adjustment movement that deviates from a linear movement along the linear direction. For this purpose, the connecting element is guided on the body of the second locking part, such that when moving from the initial position to the functional position, the connecting element is forced to move along the adjustment direction and is rotated relative to the body about the axis of rotation pointing along the linear direction.

[0045] Due to the twisting, the connecting element also performs a movement along the linear direction and is thus adjusted along the linear direction relative to the body of the second locking part, so that the connecting element is extended from the body and protrudes in the functional position relative to the body along the linear direction.

[0046] The guided movement occurs at least on part of the adjustment path. In another part of the adjustment path, a linear movement along a linear direction may occur. For example, to move from the initial position to the functional position, the connecting element may first have to be moved linearly along a linear direction until it engages with a guide device on the body of the second locking part, and then, during further movement towards the functional position, move in a guided manner relative to the body of the second locking part.

[0047] For example, the second locking part has a guide element arranged on the second body, on which the connecting element is adjustable at least along the part of its adjustment path along the direction of adjustment. For example, a guide track is formed on the guide element, along which the connecting element is guided for adjustment at least along the part of its adjustment path. The guide track can, for example, be oriented along a helix, so that the connecting element performs a guided, helical movement relative to the body of the second locking part and is thus rotated about the linear direction and adjusted linearly along the linear direction relative to the body in a superimposed manner.

[0048] In one embodiment, the connecting element has a positive locking section which, in the closed position, engages with the first locking part in a rotationally fixed manner to prevent movement of the connecting element along the adjustment direction relative to the second body. In the closed position, not only are the locking parts held together, but the connecting element is also fixed in its position relative to the body of the second locking part by preventing movement of the connecting element along the adjustment direction relative to the body of the second locking part. For this purpose, the connecting element engages with the first locking part via the positive locking section in the closed position, thus preventing any rotational movement of the connecting element in the closed position.

[0049] For example, the positive locking section can be engaged with the engagement device in a rotationally fixed manner in the closed position. For example, the head of the connecting element can have a rotationally symmetrical shape (with respect to an axis of rotation pointing along the linear direction) and, for example, form an engagement projection that extends radially outwards around the axis of rotation. In contrast, the positive locking section can deviate from a rotationally symmetrical shape, so that engagement with the engagement device can result in a rotationally fixed fixing of the connecting element to the engagement device.

[0050] For example, the positive locking section can be located between edge sections of the engagement device in the closed position, such as between edge sections of a slot opening or a receiving opening of the engagement device. The positive locking section can, for example, be flattened when viewed along a plane perpendicular to the axis of rotation and form parallel, flat wall sections facing away from each other, with which the positive locking section is in contact with the edge sections of the engagement device in the closed position. Due to the position of the positive locking section between the edge sections of the engagement device, the positive locking section and, above it, the connecting element are fixed against rotation in the closed position.

[0051] It can be provided that only the engagement of the positive locking section with the engagement device causes the connecting element to be fully moved into its functional position. For this purpose, the engagement device is preferably designed to act on the positive locking section when the engagement is established, in order to move the connecting element along the adjustment direction into a rotational position relative to the second body of the second locking part that corresponds to the functional position. For example, due to the magnetic attraction between the magnetic devices, the connecting element can be moved from its initial position towards the functional position, whereby, for example, due to an elastic preload, the connecting element is initially not moved fully into its functional position.Only when the connecting element with the positive locking section engages with the engagement device is the connecting element, due to the interaction with the engagement device, moved into a rotational position corresponding to the functional position and thus, for example, fully into the functional position against the preloading effect of a preloading element. In the functional position, the connecting element is then preferably preloaded relative to the body of the second locking part and is thus held against the body of the second locking part without play.

[0052] It should be noted that the positive locking section can also engage positively with other opposing sections on the side of the first locking part in order to fix the connecting element rotationally fixed relative to the first locking part.

[0053] In particular, the functions can also be separate: For example, the engagement device can only secure the connection along the linear direction, but still allow rotation of the connecting element. The rotation lock can then be achieved separately via one or more other form elements.

[0054] In one embodiment, the second locking part has an elastically deformable preload element designed to preload the connecting element relative to the second body, at least in the functional position. The preload element can be, for example, an elastic spring or a rubber element, such as an O-ring, extending around a rotational axis associated with the connecting element. When moved into the functional position, the preload element is elastically tensioned, so that in the functional position, an elastic preload is exerted on the connecting element relative to the body of the second locking part.

[0055] In one embodiment, the connecting element is held in its initial position relative to the second body when the locking device is open. For example, the connecting element can be spring-loaded or magnetically biased relative to the body of the second locking part in the direction of the initial position.

[0056] In one embodiment, the second locking element has a third magnetic device arranged on the second body of the second locking element, which magnetically interacts with the second magnetic device to hold the connecting element in its initial position. The third magnetic device attracts the second magnetic device so that, when the locking device is open, the connecting element is held in its initial position on the body of the second locking element.When the locking parts are brought close together, the magnetic attraction between the first magnetic device of the first locking part and the second magnetic device on the connecting element of the second locking part overrides the magnetic attraction between the second magnetic device and the third magnetic device and exceeds it as soon as the locking parts have been brought sufficiently close together, so that the connecting element is moved from the initial position to the functional position due to the magnetic attraction between the first magnetic device and the second magnetic device.

[0057] In one embodiment, the first and second locking parts are fixed in the closed position relative to each other, both along the linear direction and along a plane perpendicular to the linear direction. In the closed position, the first and second locking parts cannot be moved relative to each other, particularly not rotationally.

[0058] The fixed positioning, particularly in a plane perpendicular to the linear direction, and especially rotationally around the linear direction, can be achieved, for example, by a suitable engagement structure on the first and second locking parts. Along the linear direction, the locking parts are fixed relative to each other by the engagement of the connecting element with the engagement device.

[0059] In one embodiment, the second locking element has two connecting elements, each adjustable between a neutral position and a functional position relative to the second body. In the functional position, viewed along the linear direction, the connecting elements project relative to the second body such that they can engage with the engagement mechanism of the first locking element. In the closed position, the connecting elements engage with the engagement mechanism to hold the first and second locking elements together. Each connecting element has an associated second magnetic element for magnetic interaction with the first magnetic element of the first locking element.

[0060] For example, the engagement device on the first locking part can have two spring-loaded locking elements, each associated with one of the connecting elements. In another embodiment, the engagement device can have two engagement openings and two adjoining receiving openings, with one insertion opening and one receiving opening each being associated with one of the connecting elements.

[0061] Because the connection between the locking parts in the closed position is established via two connecting elements and their engagement with the engagement device of the first locking part, the locking parts are fixed in position relative to each other in the closed position, and in particular also rotationally fixed, thus establishing a fixed connection between assemblies that are assigned to the locking parts.

[0062] If more than two connecting elements are provided, the axes of rotation can all be in one plane, but different from each other, for example.

[0063] In one embodiment, the first locking part has a first electrical contact assembly and the second locking part has a second electrical contact assembly. When the locking device is closed, the contact assemblies, each of which may, for example, have one or more electrical contacts, come into electrical contact with each other, thus establishing an electrical connection.

[0064] The first electrical contact assembly can, for example, be formed by a first electrical connector part, and the second electrical contact assembly by a second electrical connector part. When the locking device is closed, the connector parts engage with each other in a plugging motion. The first electrical connector part and the second electrical connector part are plugged together in the closed position. The insertion direction along which the plugging connection is to be made preferably corresponds to the insertion direction.

[0065] The connector components can be used, for example, to establish a data connection or an electrical supply connection between assemblies that are associated with the locking components. The connector components can be configured, for example, with USB ports, such as USB-C ports, or other connections for electrical or electronic devices, for example, for telecommunications applications.

[0066] In one embodiment, the second connector part is arranged on the connecting element of the second locking part. For example, the first connector part can be arranged in the area of ​​a receiving opening of the engagement device of the first locking part. When the locking device is closed, the connecting element engages with the engagement device, and the connector parts come into a plug-in connection with each other, so that in addition to the mechanical fastening of the locking parts to each other, an electrical connection is also established.

[0067] The locking device is magnetically designed. The first and second magnetic elements can each be formed, for example, by permanent magnets positioned with opposite poles, thus attracting each other magnetically. In another embodiment, the first and second magnetic elements can each be formed by a permanent magnet on one side and a passive magnetic armature, for example, made of a ferromagnetic material, on the other.

[0068] If the second magnetic element is a permanent magnet, the third magnetic element can, for example, be a passive magnetic armature. In another embodiment, the third magnetic element is a permanent magnet that is magnetically attracted to the second magnetic element.

[0071] In a Fig. 1A , 1B until Fig. 6A-6E In the illustrated embodiment, a locking device 1 comprises a first locking part 2 and a second locking part 3 to be connected to the first locking part 2 along a closing direction X corresponding to a linear direction. The locking parts 2, 3 are in an open position, as shown in Fig. 2A bis 2E , separately from each other. In a closed position, shown in Fig. 6A bis 6E , in contrast, the locking parts 2, 3 are attached to each other, so that the assemblies assigned to the locking parts 2, 3 are connected to each other via the locking device 1.

[0072] The closure part 2 has a body 20 on which an engagement device 21 is formed. The engagement device 21 forms, as shown, for example, in the exploded view according to Fig. 1B as can be seen, insertion openings 210A, 210B, to which an associated receiving opening 211A, 211B is connected along an insertion direction Y.

[0073] Magnetic devices 22A, 22B are arranged in the area of ​​the insertion openings 210A, 210B on the body 20. In the illustrated embodiment, the magnetic devices 22A, 22B are designed as permanent magnets and are received in openings 200A, 200B on the body 20, as can be seen from the exploded view according to the figure. Fig. 1A results.

[0074] The locking element 3 has connecting elements 34A, 34B which are guided on guide elements 31A, 31B and above them on a body 30 of the locking element 3. The guide elements 31A, 31B are attached to the body 30 by means of retaining devices 301 in the form of locking mechanisms and accommodate the connecting elements 34A, 34B within them.

[0075] Each connecting element 34A, 34B has a magnetic device 32A, 32B in the form of a permanent magnet, which magnetically attracts a corresponding magnetic device 22A, 22B on the body 20 of the closure part 2. As can be seen from the sectional view according to Fig. 2C in conjunction with Fig. 1A As can be seen, the magnetic devices 32A, 32B are arranged in the area of ​​a head 343 of the respective associated connecting element 34A, 34B.

[0076] Each connecting element 34A, 34B has an adjusting body 340 on which the head 343 is formed. The head 343 forms an engagement projection for engaging the engagement device 21 of the locking part 2. A positive-locking section 344 with flattened side surfaces is formed between the head 343 and a cylindrical section of the adjusting body 330. A collar 341 projects radially from the adjusting body 340 and carries engagement elements 342, via which the respective connecting element 34A, 34B is guided on guide tracks 310 inside the respective associated guide part 31A, 31B.

[0077] Each guide element 31A, 31B is closed on one side facing away from a surface 300 of the body 30 by a base element 35A, 35BB, on which a third magnetic device 36A, 36B in the form of a permanent magnet is mounted. Each base element 35A, 35B has a base plate 350 from which a pin 351 projects centrally, within which the associated magnetic device 36A, 36B is mounted, as can be seen, for example, in the sectional view according to Fig. 2C as is evident.

[0078] Inside each guide part 31A, 31B a pretensioning element 33A,33B in the form of a rubber-elastic O-ring is included, which serves to pretension the respective connecting element 34A, 34B relative to the guide part 31A, 31B and thus relative to the body 30.

[0079] In the open position of the locking device 1, as shown in Fig. 2A bis 2E The locking parts 2 and 3 are separated from each other. The connecting elements 34A and 34B are located in a Fig. 2A bis 2E The initial position shown is such that the heads 343 of the connecting elements 34A, 34B are flush with the surface 300 of the body 30 and therefore do not protrude outwards. In this initial position, the connecting elements 34A, 34B are thus received inside the guide parts 31A, 31B and are therefore recessed relative to the body 30 of the locking part 3.

[0080] The magnetic devices 32A, 32B of the connecting parts 34A, 34B interact in the initial position with the magnetic devices 36A, 36B on the base elements 35A, 35B when the locking device 1 is open, and thereby hold the connecting elements 34A, 34B magnetically in the initial position.

[0081] Because the connecting elements 34A, 34B do not protrude outwards from the body 30 in the initial position, the connecting elements 34A, 34B are not obstructive when the locking device 1 is open and do not disturb an aesthetic impression, for example inside a vehicle (for example, if the locking part 3 is fixed to an associated assembly, for example on a vehicle seat, in order to enable the attachment of an assembly associated with the locking part 2 to the vehicle assembly associated with the locking part 3 by connecting it with the locking part 2).

[0082] If the locking parts 2, 3 are brought (approximately) closer together along the closing direction X, as shown from Fig. 3A bis 3E As can be seen, the locking parts 2, 3 are brought into a position relative to each other by the magnetic attraction forces between the magnetic devices 22A, 22B on locking part 2 and the magnetic devices 32A, 32B on locking part 3, in which the connecting elements 34A, 34B are opposite the insertion openings 210A, 210B of the engagement device 21 and are aligned with the insertion openings 210A, 210B along the closing direction X, as can be seen from the sectional view according to Fig. 3C as is evident.

[0083] If the locking parts 2, 3 are brought close together along the closing direction X to such an extent that the magnetic attraction forces between the magnetic devices 22A, 22B on locking part 2 and the magnetic devices 32A, 32B on locking part 3 exceed the magnetic holding forces between the magnetic devices 32A, 32B, 36A, 36B on locking part 3, then the connecting elements 34A, 34B are moved from their initial position according to Fig. 3A bis 3E outwards in the direction of a functional position relative to the body 30 of the locking part 3, as can be seen from Fig. 4A bis 4E The connecting elements 34A, 34B are thus adjusted on the guide parts 31A, 31B and thereby extended out of the body 30 through openings 302A, 302B in the surface 300, so that the connecting elements 34A, 34B with their heads 343 protrude relative to the surface 300 of the body 30.

[0084] The connecting elements 34A, 34B are guided via the engagement elements 342 on the collar 341 of the adjusting body 340 of the respective connecting element 34A, 34B on guide tracks 310 of the respective associated guide part 31A, 31B such that the connecting elements 34A, 34B perform a forced movement relative to the body 30 when moved from the initial position towards the functional position. In particular, the connecting elements 34A, 34B do not move linearly out of the guide parts 31A, 31B along the closing direction X, but are rotated about an associated axis of rotation D along an adjustment direction V on the respective associated guide part 31A, 31B when moved towards the functional position.The guide tracks 310, in the form of radially inwardly projecting, helically extended guide sections, cause, in the manner of a thread, that when rotated about the axis of rotation D along the adjustment direction V, the connecting elements 34A, 34B are also adjusted along the closing direction X relative to the body 30 in a superimposed movement and are thus transferred in the direction of the functional position in which the connecting elements 34A, 34B with their heads 343 protrude from the surface 300 of the body 30 in the direction of the locking part 2.

[0085] In the position according to Fig. 4A bis 4E The connecting elements 34A, 34B with their heads 343 are arranged in accordance with each of the bases of the associated insertion openings 210A, 210B and are located opposite the magnetic devices 22A, 22B on the body 20 of the closure part 2, as can be seen from Fig. 4C as is evident.

[0086] To fully close the locking device 1, the locking parts 2, 3 are now moved relative to each other along the insertion direction Y, which extends transversely to the closing direction X, so that the connecting elements 34A, 34B enter the receiving openings 211A, 211B along the insertion direction Y, as shown in Fig. 5A bis 5E The connecting elements 34A, 34B thus engage with the receiving openings 211A, 211B such that the connecting elements 34A, 34B with their heads 343 engage behind edge sections 212 of the receiving openings 211A, 211B and the form-fitting section 344 axially adjoining the respective head 343 engages between the associated edge sections 212, as is evident in the transition of Fig. 5A bis 5E towards Fig. 6A bis 6E as is evident.

[0087] In the illustrated embodiment, the insertion of the connecting elements 34A, 34B into the receiving openings 211A, 211B is carried out manually by a user, whereby the insertion can be assisted, for example, by gravity.

[0088] When inserted into the receiving openings 211A, 211B, the magnetic devices 22A, 22B on the closure part 2 and the magnetic devices 32A, 32B on the connecting elements 34A, 34B on the closure part 3 are tangentially separated from each other along the insertion direction Y, so that the insertion takes place against the magnetic attraction force of the magnetic devices 22A, 22B, 32A, 32B.

[0089] A locking device 24 is arranged on the body 20 of the locking part 2. This locking device has a locking element 240 that is adjustable on the body 20 transversely to the insertion direction Y and transversely to the closing direction X and is spring-loaded relative to the body 20 by a spring element 242. The locking element 240 engages with a locking lug 241 in the area of ​​the receiving opening 211B, so that when the connecting element 34B is inserted into the receiving opening 211B, its head 343 slides onto the locking lug 241, pushes it aside, and thus passes the locking element 240, as occurs in the transition of Fig. 5A-5E towards Fig. 6A-6E as is evident.

[0090] In the Fig. 6A bis 6E In the depicted closed position, the locking device 1 is thus locked, in that the connecting element 34B is blocked by the locking device 24 in the receiving opening 211B and thus the other connecting element 34A cannot slide out of the associated receiving opening 211A against the insertion direction Y or only with difficulty.

[0091] As this is shown Fig. 4A-4E and 5A-5E As can be seen, the preload element 33A, 33B of each connecting element 34A, 34B assumes an intermediate position between the collar 341 of the connecting element 34A, 34B and the body 30 when the connecting element 34A, 34B is magnetically adjusted from its initial position towards its functional position, and is elastically tensioned. The preload elements 33A, 33B ensure that the respective connecting element 34A, 34B is not yet completely transferred into a rotational position corresponding to its functional position by the magnetic interaction of the magnetic devices 22A, 22B, 32A, 32B, but a slight residual angle remains, as can be seen from Fig. 4A-4E and 5A-5E as is evident.

[0092] Only when the connecting elements 34A, 34B are inserted into the receiving openings 211A, 211B are they fully transferred into their rotational position corresponding to their functional position. This is achieved by the engagement of the positive locking section 344 with its flattened side walls between the edge sections 212 of the respective receiving opening 211A, 211B. The insertion of the positive locking section 344 between the edge sections 212 thus causes the respective connecting element 34A, 34B to rotate into the Fig. 6A-6E The illustrated end position shows the positive locking sections 344 of the connecting elements 34A, 34B engaging positively between the edge sections 212 of the receiving opening 211A, 211B and thus being positively locked between the edge sections 212.

[0093] Because the connecting elements 34A, 34B with their positive locking sections 344 engage positively between the edge sections 212 of the receiving openings 211A, 211B when the locking device 1 is in the closed position according to Fig. 6A bis 6E When the connecting elements 34A and 34B are in their rotational position relative to the body 20 of the locking part 2, and thus also relative to the body 30 of the locking part 3, the locking parts 2 and 3 are fixed relative to each other in the closed position by the arrangement of two connecting elements 34A and 34B. Because the connecting elements 34A and 34B are locked in their rotational position, they cannot rotate backward relative to the guide elements 31A and 31B in the opposite direction of adjustment V and are therefore fixed relative to the body 30 in the extended functional position.

[0094] The final rotation of the connecting elements 34A, 34B into their functional position when inserted into the receiving openings 211A, 211B causes the connecting elements 34A, 34B to extend slightly further along the closing direction X relative to the body 30, contrary to the preload of the preloading elements 33A, 33B, thus tensioning the preloading elements 33A, 33B. This preloading of the preloading elements 33A, 33B eliminates any play and ensures that the assembly is free of rattling in the closed position.

[0095] In the closed position, the connecting elements 34A, 34B are thus fixed in their position relative to the body 30 of the locking part 3. This means that the connection between the locking parts 2, 3 is independent of whether the bodies 20, 30 of the locking parts 2, 3 touch in the closed position. Rather, the connection is established solely via the connecting elements 34A, 34B and their engagement with the engagement device 21, whereby the surface 300 of the body 30 of the locking part 3 can be spaced apart from the body 20 of the locking part 2, as can be seen, for example, in the sectional views according to [reference]. Fig. 6C und 6E as is evident.

[0096] Because the bodies 20, 30 of the locking parts 2, 3 are not in contact with each other in the closed position, their surfaces facing each other can be shaped as desired. In particular, the surface 300 of the body 30 of the locking part 3 can be curved or corrugated, deviating from a flat shape. Because the connection of the locking parts 2, 3 in the closed position is independent of whether the bodies 20, 30 are in contact with each other, the shape of the bodies 20, 30 on their surfaces facing each other, or, for example, padding on the surface 300, does not impair the connection of the locking parts 2, 3.

[0097] This also makes it possible in particular to integrate one or both locking parts 2, 3 into their respective assigned assemblies, for example into a vehicle assembly, such as a vehicle seat.

[0098] If the locking direction 1 is to be reopened, a user can, for example, manually act on the locking device 24 and adjust the locking element 240 so that the locking lug 241 is removed transversely to the insertion direction Y from the area of ​​the receiving opening 211B, so that the connecting elements 34A, 34B can be pushed out of the receiving openings 211A, 211B along the insertion direction Y and the locking device 1 can thus be opened.

[0099] In the illustrated embodiment, an electrical connector part 23 is arranged on the body 20 of the closure part 2 and is located at one end of the receiving opening 211B. A corresponding mating connector part 37 is arranged on the adjusting body 340 of the connecting element 34B. In the functional position of the connecting element 34B, the mating connector part 37 is opposite the connector part 23, so that when the connecting element 34B is inserted into the corresponding receiving opening 211B along the insertion direction Y, the connector parts 23 and 37 engage with each other in a plugging motion, thus establishing an electrical connection between them.

[0100] The connector parts 23 and 37 can, for example, form an electrical connector through which data signals can be transmitted and / or an electrical supply can be provided. For example, such a connector can implement a USB connector, such as a USB-C connector.

[0101] In a modified, in Fig. 7A , 7B bis 11A-11F In the illustrated embodiment, the surface 300 of the body 30 of the closure part 3 is curved, wherein in the open position of the closure device 1, as shown in Fig. 8A bis 8F , the heads 343 of the connecting elements 34A, 34B are flush with the surface 300 in the openings 302A, 302B, thereby accommodating and continuing the curved shape of the surface 300.

[0102] In the exemplary embodiment according to Fig. 7A , 7B bis 11A-11F The guide parts 31A, 31B are formed in one piece with the body 30.

[0103] The connecting elements 34A, 34B are guided on the guide parts 31A, 31B by corresponding alignment of the guide tracks 310 along opposite adjustment directions V, V', as can be seen, for example, from Fig. 9E in the transition to Fig. 10E This is evident. When moving from their respective starting positions towards the functional position, the connecting elements 34A, 34B are thus rotated in opposite directions to each other, whereby the slope of the opposing guide tracks 310 on the guide parts 31A, 31B is the same in magnitude and thus the connecting elements 34A, 34B are extended equally far along the closing direction X.

[0104] Accordingly, the final transfer of the connecting elements 34A, 34B into the functional position when inserted along the insertion direction Y into the receiving openings 211A, 211B is also in the opposite direction, as can be seen from Fig. 10E in the transition to Fig. 11E as is evident.

[0105] Furthermore, the exemplary embodiment is according to Fig. 7A , 7B bis 11A-11F functionally identical to the previously described embodiment, so reference should also be made to the explanations regarding this.

[0106] In the described embodiments, the guide tracks 310 on the guide parts 31A, 31B are formed by radially inwardly projecting guide sections shaped like threaded sections, which force the connecting elements 34A, 34B into a helical movement when moved towards the functional position, as a result of which the connecting elements 34A, 34B are axially adjusted in a superimposed manner along the closing direction X and are also rotated about the respective associated axis of rotation D pointing along the closing direction X.

[0107] In one embodiment, shown in Fig. 12A bis 12D The adjustment movement of the connecting elements 34A, 34B is guided along helical guide tracks 310 over the entire adjustment path from the initial position in the direction of the functional position.

[0108] In another embodiment, shown in Fig. 13A, 13B In contrast, the guidance along helical guide tracks 310 only occurs over a portion of the adjustment path. Initially, when moving from the starting position, each connecting element 34A, 34B is moved linearly along the closing direction X until the engagement elements 342 interact with the guide tracks 310, and then the further movement of the connecting elements 34A, 34B from the starting position to the functional position takes place in a guided manner along the guide tracks 310 in accordance with a helical movement.

[0109] The underlying idea of ​​the invention is not limited to the embodiments described above, but can also be realized in other ways.

[0110] A locking device of the type described can be used, for example, in a vehicle to fasten objects, such as electrical or electronic devices, to a vehicle seat or to another vehicle assembly.

[0111] However, this is not a limitation. A locking device of the type described can be used to connect any number of assemblies. Bezugszeichenliste
