Description

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

Such a closure device comprises a first closure part, which has a first body, an engagement device arranged on the first body and a first magnet device, and a second closure part, which has a second body, a connecting element movably arranged on the second body and a second magnet 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 is in engagement with the engagement device for holding 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.

In the closure device, the connecting element on the second body of the second closure part is adjustable between a starting position, in which the connecting element is at least partially accommodated in the body, and a functional position, and in the functional position protrudes relative to the second body, so that the connecting element can be brought into engagement with the engagement device of the first closure part. The first magnet device and the second magnet device are designed to interact in a magnetically attractive manner when the first closure part and the second closure part approach each other in order to transfer the connecting element from the starting position to the functional position.

In one of the EN 10 2010 044 198 A1 In the known closure device, spring locking elements are arranged on a closure part, which in a closed position engage with engagement elements of a further closure part. The engagement elements are accommodated in a starting position in a housing of the further closure part, so that in the starting position the engagement elements do not protrude outwards from the housing or only protrude insignificantly. 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 locking elements to connect the closure parts.

One of the US 6 659 516 B2 A known locking device 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.

In the case of a locking device, such as that used in EN 10 2010 044 198 A1 As is known, engagement elements on one closure part are extended when closure parts approach one another in order to engage with spring locking elements on another closure part in a closed position and to establish a connection between the closure parts in the closed position. The engagement elements are pre-tensioned relative to a body of the associated closure part in the direction of the starting position, for example in a spring-elastic manner, which means that the closure parts are in pre-tensioned contact with one another in the closed position.

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 surfaces, for example on padded surfaces.

Another locking device is in the EN 10 2021 006 521 A1 described.

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, even on irregularly shaped surfaces, for example.

This object is solved by an article having the features of claim 1.

Accordingly, the connecting element can be pivoted about an axis of rotation relative to the second body in order to adjust the connecting element into the functional position in an adjustment direction directed about the axis of rotation, wherein the connecting element in the closed position is in positive engagement with the engagement device of the first closure part such that a movement of the connecting element counter to the adjustment direction relative to the first closure part is blocked due to the positive engagement.

To close the closure device, the closure parts of the closure device are moved, for example along a closing direction, approached each other. 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 transferred from the starting position to the functional position. While the connecting element is completely or partially enclosed in the body of the associated second closure part in the starting position, the connecting element in the functional position is adjusted to the body of the second closure part in such a way that the connecting element protrudes from the body and can thus be brought into engagement with the engagement device on the first closure part.

However, the adjustment of the connecting element from the starting position to the functional position when closing the locking device does not take place linearly, but rather around an axis of rotation. The connecting element can be pivoted about the associated axis of rotation to the body and can thus be pivoted like a lever element relative to the body of the second locking part in order to move from the starting position to the functional position. In the starting position, the connecting element is, for example, completely or partially enclosed in the body of the second locking part. In the functional position, on the other hand, the connecting element protrudes relative to the body of the second locking part in such a way that the connecting element can be brought into engagement with the engagement device of the first locking part and thus a connection can be established between the locking parts.

The technical advantage of an adjustment around a rotation axis is given in particular by the simple realization of a precise, almost play-free fixing of the locking parts.

If the locking parts are brought closer together to close the locking device, the connecting element is pivoted out of the starting position due to the magnetic attraction between the magnet devices. Once the connecting element has been moved into the functional position, the connecting element can be brought into engagement with the engagement device so that the locking parts are held together in the closed position.

In the closed position, the connecting element is locked on the first closure part in such a way that the connecting element cannot be adjusted relative to the body of the first closure part in the opposite direction to the adjustment direction pointing around the axis of rotation, in which direction the connecting element has been pivoted to transfer it into the functional position. With respect to the adjustment direction, the connecting element is thus fixed in the closed position on the first closure part, so that the connecting element is locked in its position with respect to the adjustment direction relative to the first closure part. Due to the engagement with the engagement device, the connecting element cannot be moved from the functional position back into the starting position when the closure device is in the closed position, at least not without the engagement between the connecting element and the engagement device of the first closure part being canceled.

This applies in particular when the first closure part is held in a fixed position relative to the second closure part in the closed position, for example because the first closure part is in contact with the second closure part or the connection is made by several (at least two) spatially distributed connecting elements. In this case, the connecting element can no longer be moved towards the second closure part due to the engagement of the connecting element with the engagement device of the first closure part.

Because the connecting element can be pivoted about a rotation axis (preferably perpendicular to a closing direction) relative to the body of the second closure part and thus has to be pivoted about the rotation axis in order to transfer from the starting position to the functional position (or vice versa from the functional position to the starting position), the connecting element carries out an adjustment movement in order to transfer between its different positions, which is not directed linearly along the closing direction and thus differs from the closing direction. The adjustability of the connecting element along the adjustment direction that is different from the closing direction can be used to lock the connecting element in its position (also) relative to the body of the second closure part when the closure device is in the closed position. In the closed position, due to the engagement of the connecting element with the engagement device, a movement of the connecting element against the adjustment direction (directed around the rotation axis) can also be blocked relative to the second body of the second closure part if the closure parts are held in a fixed position relative to one another in the closed position. Due to the locking effect, the connecting element cannot move along the adjustment direction relative to the body of the second closure part when the closure device is in the closed position and the connecting element is in engagement with the engagement device of the first closure part. Because movement along the adjustment direction is blocked, the connecting element is in its a functional position relative to the body of the second closure part, so that the connecting element cannot be adjusted from the functional position. This makes it possible to ensure that in the closed position the connecting element engages with the engagement device of the first closure part and thereby establishes the connection between the closure parts, but the body of the second closure part is not necessarily in contact with the body of the first closure part. By locking the connecting element in the functional position when the closure device is in the closed position, the bodies of the closure parts can be kept at a distance from one another, so that surface contact between the bodies of the closure parts is avoided.

This makes it possible to create a secure and reliable connection between the closure parts, even with irregularly shaped surfaces of the bodies of the closure parts, for example with a padded surface on a body, which is independent of the shape of the surfaces of the bodies of the closure parts. Signs of wear, such as scratches or grinding marks, on a padded surface, for example, can also be avoided in this way.

In one embodiment, the first closure part and the second closure part can be brought closer together in a closing direction to close the closure device, with the axis of rotation being directed at least approximately perpendicular to the closing direction. The closure parts can, for example, only be placed together along the closing direction (at least on a final part of the closing path). In another embodiment, the closure parts can also be placed together along the closing direction and also along other directions, for example transversely to the closing direction, in order to close the closure device, so that the ability of the closure parts to come closer together is not limited to the closing direction.

In one embodiment, the connecting element can be pivoted relative to the second body for transfer from the starting position to the functional position, for example by an angle between 20° and 150°, preferably between 30° and 100°, for example 45° or 90°.

The second closure part can be arranged, for example, on a (quasi-)stationary assembly, for example in a vehicle, for example on a vehicle seat. In the starting position, the connecting element is, for example, completely or partially accommodated in the body of the second closure part, so that in the starting position corresponding to a non-use position, the connecting element does not protrude outwards and is therefore not a hindrance and also does not impair the aesthetic external impression 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 one another, the connecting element is transferred from the starting position to the functional position so that the closure parts can be fastened to one another and the first closure part is thus held in position on the second closure part in the closed position of the closure device.

In one embodiment, the connecting element has a head which is held in a form-fitting manner on the engagement device in the closed position. In the closed position of the closure device, the connecting element with the head protrudes relative to the body of the second closure part and engages in the engagement device of the first closure part, so that the closure parts are fixed in a form-fitting manner to one another.

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, in particular with respect to the closing direction.

In one embodiment, the second body of the second closure part forms a surface that faces the first closure part in the closed position, the head being essentially flush with the surface in the starting position and being spaced apart from the surface in the functional position, preferably viewed along the closing direction. In the starting position, the connecting element is accommodated in the body of the second closure part in such a way that the head does not protrude outwards or only protrudes insignificantly relative to the surface of the second body, but is essentially 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 flush with the surface. In the starting position, the second closure part thus has a self-contained shape on its outward-facing surface. without the connecting element protruding disturbingly from the body of the second closure part.

In this case, substantially flush means that no sharp-edged areas of the connecting element protrude from the surface and there is no risk of injury to a user, for example in the event of a collision in a vehicle or in the event of contact, for example when a vehicle occupant gets into a vehicle.

For example, the substantially flush arrangement can create a visual unity between the surface of the second body and the visible surface of the connecting element, even if they are not exactly in one plane or are coplanar or have the same area and/or are separated by shadow gaps, bevels or radii.

When the closure parts approach each other to close the closure device, the connecting element is transferred from the starting position to the functional position and protrudes relative to the surface in the functional position. By transferring to the functional position, the connecting element can be brought into engagement with the engagement device of the first closure part in order to connect the closure parts to one another in the closed position.

In one embodiment, the surface of the second body is not in contact with the first body in the closed position. Because the connecting element is locked in its position when the locking device is in the closed position, the bodies of the locking parts can be kept at a distance from one another in the closed position, which can ensure 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 is thus made independently of the nature of the bodies of the locking parts, in particular a surface design of the bodies of the locking parts, for example padding on one of the bodies of the locking parts.

In one embodiment, the connecting element has a closing part arranged on the second body, which in the functional position is in contact with the second body. The closing part can, in particular, limit the pivoting path of the connecting element relative to the second body in the direction of the functional position by means of the contact, such that the connecting element cannot be pivoted relative to the second body beyond the functional position. In addition, the closing part can, for example, close an opening in the surface of the second body that is released by the head of the connecting element when the connecting element is in the functional position.

The engagement device of the first closure part can be designed in different ways.

For example, the engagement device can be designed to establish a locking connection with the connecting element in the closed position. For this purpose, the engagement device can have a spring locking element, for example as shown in the EN 10 2010 044 198 A1 When the locking device is closed, the connecting element thus engages with the engagement device in a locking manner and is preferably held in a form-fitting manner on the engagement device in the closed position.

Such a spring locking element or an arrangement of spring locking elements can, for example, be designed as described in different embodiments in the EP 2 389 084 B1 , the EP 2 040 572 B1 or the EP 2 254 435 B1 described.

The engagement device has an insertion opening into which the connecting element can be inserted in the functional position for closing the locking device.

In this case, it can be provided that the first magnet device is arranged on the first body of the first closure part in the region of the insertion opening and is designed to interact with the second magnet device on the connecting element of the second closure part when the first closure part and the second closure part approach each other to close the closure device in such a way that the connecting element is drawn into the insertion opening due to the magnetic attraction. For example, the first magnet device can be arranged on a base of the insertion opening so that the connecting element is moved into the insertion opening by magnetic interaction with the second magnet device on the connecting element of the second closure part and the connecting element is thus magnetically drawn into the insertion opening.

The insertion opening is followed by a receiving opening which extends from the insertion opening along an insertion direction (preferably different from the closing direction, for example transverse or oblique to the closing direction) and into which the connecting element after insertion into the insertion opening, it can be pushed in the insertion direction in order to move the locking device into the closed position. The locking device is thus closed in such a way that the connecting element is first inserted into the insertion opening along the closing direction and then pushed transversely to the closing direction into the receiving opening adjacent to the insertion opening. In the closed position, the connecting element is, for example, positively engaged with the receiving opening so that the locking parts are held together.

For example, the insertion direction can be directed along the axis of rotation about which the connecting element can be pivoted relative to the body of the second closure part.

The insertion direction can be linear or can also point along a curved, arc-shaped path of movement. In particular, the insertion direction can point around the closing direction, so that the closure parts can be connected to one another by a rotary movement around the closing direction. This can be advantageous, for example, if several, for example three or more, connecting elements are provided.

For example, the receiving opening has at least one edge section. In the closed position, the connecting element engages behind the at least one edge section, so that a positive connection is created between the connecting element and the engagement device and the closure parts are fixed to one another in a positive fit.

In this text, a positive engagement or a positive connection is understood to mean that the locking parts are caught together due to the shape of the engagement device on the one hand and the connecting element on the other, and thus cannot be separated from each other, at least not without removing the positive connection. The positive connection can have play. Surfaces of engagement projections that engage with each other can also be beveled or curved, for example spherical in shape.

For example, the receiving opening has a slot opening through which the connecting element engages in the closed position. The slot opening can be defined, for example, between edge sections of the receiving opening, which extend approximately parallel to one another along the insertion direction, or at an oblique angle to the insertion direction, so that a tapered slot opening is produced that tapers in the insertion direction. In the closed position, the connecting element engages behind the edge sections of the slot opening with its head, for example an engagement projection formed on the head, so that there is a positive engagement between the connecting elements and the engagement device.

In one embodiment, the receiving opening has an engagement groove extending along the insertion direction, into which the connecting element engages in the closed position. The engagement groove can preferably be recessed with respect to a plane perpendicular to the adjustment direction. For example, the connecting element has an engagement web extending along the insertion direction, which can be inserted into the engagement groove along the insertion direction and engages in the engagement groove in the closed position. The engagement is preferably such that, due to the engagement of the engagement web in the engagement groove, the connecting element is (also) fixed to one another in a direction perpendicular to the insertion direction and the adjustment direction.

For example, due to the engagement of the connecting element in the engagement device, the connecting element can be fixed in the closed position along a plane perpendicular to the axis of rotation relative to the first closure part. Due to the engagement of the connecting element with the engagement device, the connecting element, viewed along the plane perpendicular to the axis of rotation, is fixed in a form-fitting manner relative to the first closure part and is thus caught, wherein the connecting element is preferably held on the first closure part in a rotationally and positionally fixed manner.

In one embodiment, the first closure part has a locking device that is designed to lock the connecting element to block a movement counter to the insertion direction from the closed position. The connecting element can be pushed into the receiving opening in the insertion direction, with the locking device being 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 blocked or at least made more difficult by the locking device.

For example, the locking device can have a locking element that is spring-elastically adjustable to the first body, past which the connecting element can be moved in the insertion direction to transfer it into the closed position, which prevents movement of the connecting element against the insertion direction out of the closed position however, it is locked. When moving in the insertion direction, the connecting element pushes the locking element aside, for example, so that the locking element can 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, so that moving the connecting element back out of the receiving opening is blocked or made difficult.

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 it is moved back against the direction of insertion and the connecting element is thus locked in the receiving opening.

To make opening more difficult, the locking element can be bevelled, for example, 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.

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 it.

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 that extends around an adjusting body of the connecting element. When transferred to the functional position, the prestressing element is elastically tensioned, so that in the functional position an elastic prestress is exerted on the connecting element relative to the body of the second closure part.

In one embodiment, the connecting element is held in the starting position relative to the second body in an open position of the closure device. For example, the connecting element can be spring-mechanically or magnetically prestressed relative to the body of the second closure part in the direction of the starting position.

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

In one embodiment, the first closure part and the second closure part are fixed in position relative to one another in the closed position, in particular when viewed along the closing direction and along a plane perpendicular to the closing direction. In the closed position, the first closure part and the second closure part cannot therefore be moved relative to one another, in particular not even in a rotational manner.

The positionally fixed fixing, in particular in a plane perpendicular to the closing direction, in particular rotationally about the closing direction, can be achieved, for example, by a suitable engagement structure on the first closure part and the second closure part.

In one embodiment, the second closure part has at least two connecting elements, each of which can be pivoted between a starting position and a functional position relative to the second body and, in the functional position, protrude relative to the second body in such a way 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 are each in engagement with the engagement device for holding the first closure part and the second closure part against one another. The connecting elements each have an associated second magnet device for magnetic interaction. ken with the first magnetic device of the first closure part.

For example, the engagement device on the first closure part can have two spring locking elements, each of which is assigned to one of the connecting elements. In another embodiment, two insertion openings and two adjoining receiving openings can be formed on the engagement device, with one insertion opening and one receiving opening each being assigned to one of the connecting elements.

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

In one embodiment, the connecting elements are arranged next to one another, for example along a transverse direction perpendicular to the closing direction and the rotation axis. In the closed position, the connecting elements are brought closer to the body of the first closure part, for example from opposite sides.

In one embodiment, the connecting elements can be pivoted about a common axis of rotation relative to the second body.

In another embodiment, the connecting elements can be pivoted relative to the second body about two axes of rotation that extend parallel to one another and are spaced apart from one another. In this embodiment, each connecting element is thus assigned an individual axis of rotation, with the axes of rotation extending parallel to one another.

In one embodiment, the connecting elements can be pivoted relative to the second body by an angle between 20° and 150°, preferably between 30° and 100°, for transfer from the starting position to the functional position. In the starting position, the head of each locking element lies, for example, in an associated opening on a surface of the second closure part and thus does not protrude, or only slightly protrudes, from the body of the second closure part. By pivoting about the respectively associated axis of rotation, the connecting elements can be adjusted out of the body and protrude outwards relative to the body in the functional position, the pivoting movement taking place at such an angle that the connecting elements can each be brought into engagement with the engagement device on the first body of the first closure part.

In one embodiment, the connecting elements can be pivoted in opposite directions about a common axis of rotation or about an associated, individual axis of rotation relative to the second body in order to transfer them from the starting position to the functional position. The connecting elements are thus pivoted in opposite directions to one another towards the body of the second closure part in order to transfer them to the functional position.

In another embodiment, the connecting elements can also be pivoted in the same direction.

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

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, so that an electrical connection is established.

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 locking 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. An insertion direction along which the plug-in connection is to be established preferably corresponds to the insertion direction.

The connector parts can be used, for example, to establish a data connection or to establish an electrical supply connection between assemblies that are assigned to the closure parts. The connector parts can be formed, for example, by USB ports, for example USB-C ports, or other ports for electrical or electronic devices, for example for telecommunications applications.

In one embodiment, the second electrical contact assembly, for example 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 a receiving opening of the engagement device of the first closure part. If the connecting element is brought into engagement with the engagement device when the closure device is closed, the connector parts come into a plug-in connection with one another, so that in addition to the mechanical fastening of the closure parts to one another, an electrical connection is also established.

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 one another with opposite poles and thus attracts one another magnetically. 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.

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 which is magnetically attractive to the second magnetic device.

One or more of the magnetic devices can also be formed by electromagnets, for example.

In a 1A , 1B until 5A-5E In the embodiment shown, 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 closing direction X. The closure parts 2, 3 are in an open position, shown in 2A to 2E , separated from each other. In a closed position, shown in 5A to 5E , 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 forms, as can be seen for example from the exploded view according to 1B As can be seen, insertion openings 210A, 210B, each of which is connected along an insertion direction Y to an associated receiving opening 211A, 211B.

Magnetic devices 22A, 22B are arranged in the area of the insertion openings 210A, 210B on the body 20. The magnetic devices 22A, 22B are designed as permanent magnets in the embodiment shown and are accommodated in associated mounting openings on the body 20, as can be seen from the exploded view according to 1A results.

The closure part 3 has connecting elements 34A, 34B, which are pivotably mounted about a common axis of rotation D via an axle element 348 on a bearing section 303 and above that on a body 30 of the closure part 3. The axis of rotation D extends perpendicular to the closing direction X and points along the insertion direction Y.

Each connecting element 34A, 34B has a magnetic device 32A, 32B in the form of a permanent magnet, which interacts in a magnetically attractive manner with a respective associated magnetic device 22A, 22B on the body 20 of the closure part 2. As can be seen from the sectional view according to 2D in conjunction with 1A As can be seen, the magnetic devices 32A, 32B are arranged in the region of a head 343 of the respectively associated connecting element 34A, 34B.

Each connecting element 34A, 34B has an adjusting body 340 which extends in an arc shape (on an approximately constant radius) around the axis of rotation D and on which the head 343 is formed. Each head 343 forms an engagement web 347 for engaging in an engagement groove 213 in an associated receiving opening 211A, 211B of the engagement device 21 of the closure part 2. The adjusting body 340 is mounted on the axle element 348 via a lever arm 345 and can thus pivot about the axis of rotation D relative to the body 30 of the closure part 3.

A closing part 346 is formed on the adjusting body 340 of the respective connecting element 34A, 34B, which protrudes radially to the adjusting body 340 and is flat, so that in a functional position of the respective connecting element 34A, 34B an associated opening 302A, 302B formed on the surface 300 of the body 30 is closed by the closing part 346, as can be seen from 5A and 5B is evident.

The locking part 346 serves as a stop to limit the pivoting path of the respective connecting element 34A, 34B relative to the body 30. In the functional position, the closing part 346 rests against the body 30, so that the respective connecting element 34A, 34B cannot be pivoted relative to the body 30 beyond the functional position.

Magnetic devices 36A, 36B in the form of permanent magnets are arranged on the body 30 of the closure part 3, which interact in a magnetically attractive manner with the magnetic devices 32A, 32B of the connecting elements 34A, 34B, so that, when the closure device 1 is open, the connecting elements 34A, 34B are held in their assumed position corresponding to an initial position.

In the open position of the locking device 1, shown in 2A to 2E , the closure parts 2, 3 are separated from each other. The connecting elements 34A, 34B are located in the 2A to 2E shown starting position, in which the heads 343 of the connecting elements 34A, 34B are flush with the surface 300 of the body 30 and thus do not protrude outwards. In the starting position, the connecting elements 34A, 34B are thus accommodated inside the guide parts 31A, 31B and sunk relative to the body 30 of the closure part 3.

In the initial position when the closure device 1 is open, the magnetic devices 32A, 32B of the connecting parts 34A, 34B interact with the stationary magnetic devices 36A, 36B on the body 30 of the closure part 3 and thereby hold the connecting elements 34A, 34B magnetically in the initial position.

Because the connecting elements 34A, 34B do not protrude outward from the body 30 in the initial position, the connecting elements 34A, 34B are not obstructive when the closure device 1 is open and also do 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).

If the closure parts 2, 3 are brought closer together (for example approximately along the closing direction X), as is shown in 3A to 3E As can be seen, the closure parts 2, 3 are brought into a position relative to one another due to the magnetic attraction forces between the magnet devices 22A, 22B on the closure part 2 and the magnet devices 32A, 32B on the closure part 3, in which the connecting elements 34A, 34B assume a position opposite the insertion openings 210A, 210B, as can be seen from the sectional view according to 3D is evident.

If the closure parts 2, 3 are brought close to each other to such an extent that the magnetic attraction forces between the magnetic devices 22A, 22B on the closure part 2 and the magnetic devices 32A, 32B on the closure part 3 exceed the magnetic holding forces between the magnetic devices 32A, 32B, 36A, 36B on the closure part 3, the connecting elements 34A, 34B are moved from the initial position according to 3A to 3E out in the direction of the functional position relative to the body 30 of the closure part 3, as can be seen from 4A to 4E can be seen. The connecting elements 34A, 34B are thus pivoted about the common axis of rotation D relative to the body 30 of the closure part 3 and thereby moved with the adjusting body 340 through the associated opening 302A, 302B in the surface 300 of the body 30, so that the connecting elements 34A, 34B protrude with their heads 343 relative to the surface 300 of the body 30.

In the embodiment shown, the connecting elements 34A, 34B are used to transfer from the starting position ( 3A to 3E) into the functional position ( 4A to 4E) pivoted by an angle between 30° and 60°, for example approximately 45°, relative to the body 30 of the closure part 3. The pivoting takes place about a common axis of rotation D defined by the axis element 348, wherein the connecting elements 34A, 34B are adjusted in mutually opposite adjustment directions V relative to the body 30, as can be seen in particular from 4D in conjunction with 3D is evident.

Due to the magnetic attraction between the magnetic devices 22A, 22B of the closure part 2 and the magnetic devices 32A, 32B of the connecting elements 34A, 34B, the connecting elements 34A, 34B are drawn into the insertion openings 210A, 210B of the engagement device 21 of the closure part 2, as can be seen from 4A to 4E In the position according to 4A to 4E the connecting elements 34A, 34B with their heads 343 are in contact with a respective bottom of the associated insertion opening 210A, 210B and are located in a position opposite the magnetic devices 22A, 22B on the body 20 of the closure part 2, as can be seen from 4D is evident.

To completely close the closure device 1, the closure parts 2, 3 are now inserted along the insertion direction Y, which is transverse to the Closing direction X and points along the axis of rotation D, are displaced relative to each other so that the connecting elements 34A, 34B slide into the receiving openings 211A, 211B along the insertion direction Y, as can be seen from 5A to 5E can be seen. The connecting elements 34A, 34B thus come into engagement with the receiving openings 211A, 211B in such a way that the connecting elements 34A, 34B engage with their heads 343 behind edge sections 212 of the receiving openings 211A, 211B.

On the head 343 of each connecting element 34A, 34B, an engagement web 347 is formed, which projects from the head 343 in the opposite direction to the respective associated adjustment direction V (so to speak backwards with respect to the transfer direction from the starting position to the functional position). When the connecting elements 34A, 34B are inserted into the receiving openings 211A, 211B, the respective engagement web 347 is inserted into an associated, complementary engagement groove 213 on an edge section 212, as can be seen in particular from 5B in conjunction with 5D In the closed position according to 5A to 5E the head 343 of each connecting element 34A, 34B is thus engaged with the associated receiving opening 211A, 211B in such a way that the head 343 is completely caught on the engagement device 21 in a plane perpendicular to the axis of rotation D and is thus locked in the plane perpendicular to the axis of rotation D relative to the engagement device 21.

In the closed position, each connecting element 34A, 34B is locked on the engagement device 21, in particular against the associated adjustment direction V pointing around the axis of rotation D, so that the respective connecting element 34A, 34B cannot be removed from the body 20 of the closure part 2 against the adjustment direction V, at least not without the connecting element 34A, 34B being pushed out of engagement with the engagement device 21 against the insertion direction Y and the engagement thus being canceled.

Because the connecting elements 34A, 34B are jointly fixed to the engagement device 21 and thus to the body 20 of the closure part 2, the closure parts 2, 3 are fixed in position relative to one another in the plane perpendicular to the axis of rotation D.

In the closed position, the openings 302A, 302B in the surface 300 of the body 30 of the closure part 3 are closed by the closing parts 346 of the connecting elements 34A, 34B, as can be seen from 5A to 5E The locking parts 346 are in each case in contact with the body 30 from the inside in such a way that the connecting elements 34A, 34B cannot be adjusted any further in the respectively associated adjustment direction V.

In the embodiment shown, the connecting elements 34A, 34B are inserted into the receiving openings 211A, 211B manually by a user, whereby the insertion can be assisted by gravity, for example.

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 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 22A, 22B, 32A, 32B.

In the 1A , 1B until 5A to 5E In the exemplary embodiment shown, for example, a locking device can be arranged on the body 20 of the closure part 2, which has a locking element that is adjustable on the body 20 transversely to the insertion direction Y and is spring-loaded relative to the body 20, for example via a spring element. Such a locking element can, for example, engage with a locking nose in the area of one or both of the receiving openings 211A, 211B, so that the respective connecting element 34A, 34B slides with its head 343 onto the locking nose when inserted into the receiving opening 211A, 211B, pushes it aside and thus passes the locking element. In the closed position, the closure device 1 is then locked in that the respective connecting element 34A, 34B is blocked in the receiving opening 211A, 211B by the locking device and thus cannot slide out of the associated receiving opening 211A, 211B against the insertion direction Y. If the locking device 1 is to be opened again, a user can, for example, act on the locking device manually and adjust it 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.

In the closed position according to 5A to 5E the connecting elements 34A, 34B are fixed in their position relative to the body 30 of the closure part 3 because the connecting elements 34A, 34B jointly engage in the engagement device 21 and are fixed relative to the engagement device 21. The connecting elements 34A, 34B are thereby and by the locking parts 346 in contact with the body 30 completely fixed in their position relative to the body 30. This has the consequence that the connection between the closure parts 2, 3 is independent of whether the bodies 20, 30 of the closure parts 2, 3 touch in the closed position. Rather, the connection is established solely via the connecting elements 34A, 34B and their engagement in the engagement device 21, wherein the surface 300 of the body 30 of the closure part 3 can be spaced apart from the body 20 of the closure part 2, as can be seen, for example, from 5A to 5E is evident.

Because the bodies 20, 30 of the closure parts 2, 3 do not rest against one another in the closed position, the bodies 20, 30 of the closure parts 2, 3 can have any shape on their mutually facing sides. In particular, the surface 300 of the body 30 of the closure part 3 can be curved or wavy instead of a flat shape. Because the connection of the closure parts 2, 3 in the closed position is independent of the bodies 20, 30 resting against one another, the shape of the bodies 20, 30 on their mutually facing sides or, for example, padding on the surface 300 does not affect the connection of the closure parts 2, 3.

This also enables, in particular, an integration of one or both closure parts 2, 3 into respectively assigned assemblies, for example into a vehicle assembly, for example into a vehicle seat.

In another, in 6A, 6B to 10A-10E In the embodiment shown, the connecting elements 34A, 34B of the closure part 3 are each pivotably mounted about an individual axis of rotation D on an associated axis element 348A, 348B and above that on an associated bearing section 303 of the body 30 of the closure part 3.

The connecting elements 34A, 34B are to be pivoted in opposite directions to each other in order to move the connecting elements 34A, 34B from the starting position ( 7A to 7E) into the functional position ( 9A-9E) to swivel.

While in the embodiment according to 1A, 1B to 5A-5E the connecting elements 34A, 34B are to be pivoted by an angle between 30° and 60°, for example approximately 45°, relative to the body 30 of the closure part 3 in order to pivot the connecting elements 34A, 34B between the initial position and the functional position, the connecting elements 34A, 34B in the embodiment according to 6A, 6B to 10A-10E by an angle of approximately 90° relative to the body 30 of the closure part 3.

In the closed position, shown in 10A to 10E , the heads 343 of the connecting elements 34A, 34B thus point towards each other, wherein the body 20 of the closure part 2 assumes an intermediate position between the heads 343 of the connecting elements 34A, 34B.

Furthermore, the embodiment according to 6A, 6B to 10A-10E functionally equivalent to the embodiment according to 1A, 1B to 5A-5E , so reference should also be made to the preceding explanations.

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

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

However, this is not limiting. A locking device of the type described can be used to connect any number of assemblies to one another.
