Definitions
- 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.
- first closure part and the second closure part can be placed against one another.
- the connecting element is in engagement with the engagement device for holding the first closure part and the second closure part against one another.
- 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.
- the connecting element on the second body of the second closure part is adjustable along an adjustment path between an initial position, in which the connecting element is at least partially accommodated in the body, and a functional position and protrudes in the functional position, viewed along a linear direction, 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 into the functional position.
- spring locking elements are arranged on a closure part, which in a closed position engage with engagement elements of another closure part.
- the engagement elements are accommodated in a housing of the other closure part in an initial position, so that in the initial position the engagement elements do not protrude outwards from the housing or only protrude insignificantly. From the initial position, the engagement elements can be adjusted relative to the housing, so that in a functional position the engagement elements protrude from the housing and can be brought into engagement with the spring locking elements to connect the closure parts.
- a locking device known from US 6,659,516 for locking a laptop computer in a closed position has a hook element which is received in an initial position in an associated housing and can be pivoted out of the housing for locking.
- engagement elements on one locking part are extended when locking parts approach each other in order to engage with spring locking elements on another locking part in a closed position and to establish a connection between the locking parts in the closed position.
- the engagement elements are pre-tensioned relative to a body of the associated locking part in the direction of the starting position, for example with a spring elasticity, which means that the locking parts are in pre-tensioned contact with each other in the closed position.
- 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.
- the connecting element is guided on the second body at least over a part of the adjustment path in such a way that the connecting element can be rotated relative to the second body about an axis of rotation pointing along the linear direction for adjustment between the starting position and the functional position and can be moved along the linear direction due to a rotation.
- the closure parts of the closure device are brought closer together in a linear direction. Due to the magnetic interaction of the magnetic devices on the side of the first closure part and the connecting element of the second closure part, when the closure parts come closer together, the connecting element of the second closure part is moved 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 in a linear direction and can thus be brought into engagement with the engagement device on the first closure part.
- the linear direction can, for example, approximately correspond to a closing direction along which the first closure part and the second closure part can be brought closer to one another in order to close the closure device.
- the closure parts can, for example, be attached to one another exclusively along the closing direction (at least on the last part of the closing path).
- the closure parts can also be attached to one another 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 approach one another is not limited to the closing direction.
- the adjustment of the connecting element from the initial position to the functional position when closing the locking device does not take place (exclusively) linearly along the linear direction, but at least over part of the adjustment path in a guided manner along a rotational adjustment direction that differs from the linear direction.
- the adjustment movement of the connecting element for transferring from the starting position to the functional position when closing the locking device therefore contains superimposed movement components in which a superimposed adjustment takes place on the one hand along the linear direction and on the other hand along a direction that rotates around the linear direction and which have the result that when the locking parts approach one another, the connecting element is adjusted relative to the body of the second locking part in such a way that the connecting element protrudes relative to the body along the linear direction in the functional position.
- the movement of the connecting element therefore does not take place purely in a straight line along the linear direction. Rather, the connecting element moves in a guided manner along a movement path that deviates from the linear direction.
- the connecting element is thus guided rotatably at least over a part of the adjustment path to the body of the second closure part, wherein a direction vector component of the rotational movement points along the linear direction and a further direction vector component points rotationally around the direction of rotation.
- the connecting element is not necessarily guided along the entire adjustment path to carry out a rotary movement on the body of the associated second closure part.
- the connecting element can initially be moved linearly along the linear direction to transfer from the starting position to the functional position, with a movement along a helical line directed around the linear direction taking place on part of the adjustment path, for example on the last part of the adjustment path before reaching the functional position.
- the connecting element thus carries out an adjustment movement that deviates from a linear movement along the linear direction in that the connecting element is rotated relative to the body of the associated second closure part during adjustment.
- the connecting element is guided on the body of the second closure part so that when the connecting element is moved from the starting 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. Due to the rotation, 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 closure part, so that the connecting element is extended from the body and protrudes along the linear direction relative to the body in the functional position.
- the guided movement takes place at least over part of the adjustment path.
- a linear movement along the linear direction can take place.
- the connecting element can first be moved linearly along the linear direction until the connecting element comes into operative connection with a guide device on the body of the second closure part, in order to then move in a guided manner relative to the body of the second closure part during further transfer in the direction of the functional position.
- the second closure part has a guide part arranged on the second body, on which the connecting element is adjustably guided at least over part of the adjustment path along the adjustment direction.
- a guide track is formed on the guide part, along which the connecting element is guided at least on the part of the adjustment path for adjustment along the adjustment direction.
- the guide track can, for example, be directed along a screw line, so that the connecting element carries out a guided, helical movement relative to the body of the second closure part and is thus rotated in a superimposed manner about the linear direction and adjusted linearly along the linear direction relative to the body.
- the connecting element is movable relative to the second body at least over part of the adjustment path along the adjustment direction for transfer from the starting position to the functional position, wherein in the closed position a movement of the connecting element along the adjustment direction relative to the second body is blocked due to the engagement of the connecting element with the engagement device.
- the adjustability of the connecting element along the adjustment direction different from the linear direction can be used to adjust the connecting element to lock in its position relative to the body of the second closure part when the closure device is in the closed position.
- a movement of the connecting element along the adjustment direction relative to the second body of the second closure part is blocked.
- 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 a movement along the adjustment direction is blocked, the connecting element is fixed in its functional position relative to the body of the second closure part, so that the connecting element cannot be adjusted from the functional position.
- 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.
- the connecting element In the initial position, the connecting element is, for example, completely or partially accommodated in the housing of the second closure part, so that in the initial position corresponding to a non-use position, the connecting element does not protrude outwards and is therefore not a hindrance and also does not impair the aesthetic external appearance of the associated assembly.
- the first closure part on the other hand, can be arranged on an assembly that is to be fixed in a vehicle, for example on an electrical or electronic Assembly such as a mobile phone or a navigation device or on a holding device such as a storage compartment, a coat hanger, a table or the like.
- the connecting element has a head which is held in a form-fitting manner on the engagement device in the closed position.
- the connecting element with the head protrudes relative to the housing 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 with respect to the linear direction.
- 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 along the linear direction in the functional position.
- the connecting element is received 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.
- the second closure part thus has a self-contained shape on its outward-facing surface, without the connecting element protruding in a disruptive manner from the body of the second closure part.
- substantially flush means that no sharp-edged areas of the connecting element protrude from the surface.
- the fastener shall not protrude more than 25 mm outwards relative to the surface when the fastener is in its initial position.
- the connecting element 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 in the functional position protrudes towards the surface along the linear direction. 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.
- the surface of the second body does not contact the first body in the closed position. Because the connecting element is locked in its position relative to the body of the second closure part when the closure device is in the closed position, the bodies of the closure parts can be kept at a distance from one another in the closed position, whereby it can be achieved that in particular the surface of the second closure part does not contact the body of the first closure part.
- the connection of the closure parts is thus independent of the nature of the bodies of the closure parts, in particular a surface design of the bodies of the closure parts, for example padding on one of the bodies of the closure parts.
- the engagement device of the first closure part can be designed in different ways.
- the engagement device can be designed to establish a latching connection with the connecting element in the closed position.
- the engagement device can have a spring locking element, for example as described in DE 10 2010 044 198 A1.
- the connecting element When the locking device is closed, the connecting element thus engages with the engagement device in a latching manner and is preferably held in a form-fitting manner on the engagement device in the closed position.
- the engagement device has an insertion opening into which the connecting element can be inserted in the functional position for closing the closure device.
- 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.
- the first magnet device can be arranged on a base of the insertion opening so that the connecting element is moved along the linear direction 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.
- a receiving opening can be connected to the insertion opening, which extends from the insertion opening along an insertion direction that is transverse to the linear direction and into which the connecting element can be pushed in the insertion direction after being inserted into the insertion opening in order to move the closure device into the closed position.
- the closure device is thus closed in such a way that the connecting element is first inserted into the insertion opening along the linear direction and then pushed transversely to the linear direction into the receiving opening that adjoins the insertion opening.
- the connecting element In the closed position, the connecting element is, for example, positively engaged with the receiving opening so that the closure parts are held together.
- the receiving opening has at least one edge section.
- 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.
- a positive engagement or a positive connection is to be understood as meaning that the locking parts are caught together with respect to the linear direction due to the shape of the engagement device on the one hand and the connecting element on the other hand and thus cannot be separated from each other along the linear direction, at least not without removing the positive connection.
- the positive connection can be subject to play.
- Surfaces of Engagement projections that engage with each other can also be beveled or curved to the linear direction, for example, can be spherical in shape.
- one or more wedge surfaces can be formed on the first closure part, onto which the connecting element runs when the connecting element is pushed into the receiving opening in the insertion direction.
- the connecting element can be fixed axially to the engagement device along the linear direction (in and against the linear direction) without any play.
- the keel surface can, for example, be formed on at least one edge section.
- a first wedge surface can be formed, for example, on a side of the edge section facing outwards towards the second closure part, while a second wedge surface can be formed on a side of the edge section facing inwards away from the second closure part.
- the connecting element is designed to interact with both wedge surfaces for axial fixing by wedging when inserted into the receiving opening.
- 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, for example, 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.
- 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.
- the first closure part has a locking device which is designed to lock the connecting element to block a movement against the insertion direction from the closed position.
- the connecting element can be pushed into the receiving opening in the insertion direction, the locking device being passed during the insertion movement. If the closure device is in the closed position, the However, the locking device blocks or at least makes it difficult for the connecting element to be removed from the receiving opening in the opposite direction to the insertion direction.
- the locking device can have a locking element that is spring-elastically adjustable relative to the first body, past which the connecting element can be moved in the insertion direction to move it into the closed position, but which blocks movement of the connecting element against the insertion direction from the closed position.
- the connecting element pushes the locking element aside, for example, so that the locking element can be passed.
- the locking element snaps back into a locking position due to the spring-elastic preload, so that moving the connecting element back out of the receiving opening is blocked or made more 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 thus the connecting element is locked or hindered in the receiving opening.
- 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.
- 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.
- the connecting element has a form-fitting section which, in the closed position, engages the first closure part in a rotationally fixed manner in order to block movement of the connecting element along the adjustment direction relative to the second body.
- the connecting element In the closed position, not only the closure parts are connected to one another held, but also the position of the connecting element is fixed relative to the body of the second closure part by blocking movement of the connecting element along the adjustment direction relative to the body of the second closure part.
- the connecting element is in engagement with the first closure part via the form-fitting section in the closed position, so that a twisting movement of the connecting element is blocked in the closed position.
- the form-fitting section can engage the engagement device in a rotationally fixed manner in the closed position.
- a 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 runs around the axis of rotation and projects radially outwards.
- the form-fitting section can, on the other hand, deviate from a rotationally symmetrical shape, for example, so that engagement with the engagement device can cause the connecting element to be fixed to the engagement device in a rotationally fixed manner.
- the form-fitting section can be located in the closed position between edge sections of the engagement device, for example between edge sections of a slot opening of a receiving opening of the engagement device.
- the form-fitting section can be flattened, for example, viewed along a plane perpendicular to the axis of rotation, and form flat wall sections facing away from one another and running parallel to one another, with which the form-fitting section is in contact with the edge sections of the engagement device in the closed position. Due to the position of the form-fitting section between the edge sections of the engagement device, the form-fitting section and above it the connecting element are fixed in a rotationally fixed manner in the closed position.
- the engagement device is preferably designed to act on the form-fitting section when the engagement is established in order to move the connecting element along the adjustment direction into a rotational position associated with the functional position relative to the second body of the second closure part.
- the connecting element can be transferred from the starting position towards the functional position, for example due to an elastic Pre-tensioning means that the connecting element is not initially moved completely into the functional position.
- the connecting element Only when the connecting element with the form-fitting section comes into engagement with the engagement device is the connecting element transferred into a rotational position associated with the functional position due to the interaction with the engagement device and thus moved completely into the functional position, for example against the pre-tensioning effect of a pre-tensioning element. In the functional position, the connecting element is then preferably pre-tensioned relative to the body of the second closure part and is thus held on the body of the second closure part without play.
- form-fitting section can also engage in a form-fitting manner with other counter-sections on the side of the first closure part in order to fix the connecting element in a rotationally fixed manner relative to the first closure part.
- the functions can also be separate: for example, the engagement device can only fix the connection in a linear direction, but still allow the connection element to rotate.
- the rotation lock can then be achieved separately using one or more other form elements.
- the second closure part has an elastically deformable prestressing element which is designed to prestress the connecting element relative to the second body at least in the functional position.
- the prestressing element can be formed, for example, by an elastic spring or by a rubber element, for example an O-ring, which extends around an axis of rotation associated with the connecting element.
- the prestressing 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.
- the connecting element is held in the starting position relative to the second body in an open position of the closure device.
- 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.
- the second closure part has a third magnet device arranged on the second body of the second closure part, which is magnetically connected to 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.
- first closure part and the second closure part are fixed in position relative to one another in the closed position, viewed along the linear direction and along a plane perpendicular to the linear direction. In the closed position, the first closure part and the second closure part cannot therefore be moved relative to one another, in particular not even in a rotational manner.
- the fixed position in particular in a plane perpendicular to the linear direction, in particular rotationally around the linear direction, can be achieved, for example, by a suitable engagement structure on the first closure part and the second closure part.
- the closure parts are fixed to one another via the engagement of the connecting element in the engagement device.
- the second closure part has at least two connecting elements, each of which is adjustable between an initial position and a functional position relative to the second body and, in the functional position, viewed along the linear direction, 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.
- the connecting elements In the closed position, the connecting elements each engage 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 with the first magnet device of the first closure part.
- 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.
- two engagement 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.
- 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.
- the axes of rotation can all be in the same plane, but different from each other, for example.
- the first closure part has a first electrical contact assembly and the second closure part has a second electrical contact assembly.
- 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.
- 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 connected, for example, by USB ports, for example USB-C ports, or other ports for electrical or electronic devices, for example for telecommunications applications.
- the second connector part is arranged on the connecting element of the second closure part.
- 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.
- 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.
- the third magnetic device can be formed, for example, by a passive magnetic armature.
- 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.

- Fig. 13A is a sectional view according to Fig. 12C, in another embodiment of the guide parts.
- Fig. 13B is a sectional view of Fig. 12D according to the other embodiment.
- 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 corresponding to a linear direction.
- the closure parts 2, 3 are separated from one another in an open position, shown in Fig. 2A to 2E.
- a closed position shown in Fig. 6A to 6E, 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 Fig. 1 B, insertion openings 210A, 210B, to which an associated receiving opening 211A, 211B adjoins in each case along an insertion direction Y.
- Magnetic devices 22A, 22B are arranged in the region of the insertion openings 210A, 210B on the body 20.
- the magnetic devices 22A, 22B are designed as permanent magnets and are accommodated in openings 200A, 200B on the body 20, as can be seen from the exploded view according to Fig. 1A.
- the closure part 3 has connecting elements 34A, 34B which are guided on guide parts 31A, 31B and above that on a body 30 of the closure part 3.
- the guide parts 31A, 31B are attached to the body 30 via holders 301 in the form of locking devices and accommodate the connecting elements 34A, 34B in their interior.
- 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 respectively associated magnetic device 22A, 22B on the body 20 of the closure part 2.
- 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 on which the head 343 is formed.
- the head 343 forms an engagement projection for engaging in the engagement device 21 of the closure part 2.
- a form-fitting 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 in the interior of the respectively associated guide part 31A, 31B.
- Each guide part 31A, 31B is closed on a 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 accommodated.
- Each base element 35A, 35B has a base plate 350, from which a pin 351 protrudes centrally, within which the associated magnetic device 36A, 36B is accommodated, as can be seen, for example, from the sectional view according to Fig. 2C.
- each guide part 31A, 31B there is a prestressing element 33A.33B in the form of a rubber-elastic O-ring, which serves to prestress the respective connecting element 34A, 34B relative to the guide part 31A, 31B and thus relative to the body 30.
- the closure parts 2, 3 are separated from each other.
- the connecting elements 34A, 34B are in a starting position shown in Fig. 2A to 2E, 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.
- the connecting elements 34A, 34B are thus accommodated inside the guide parts 31A, 31B and thus countersunk relative to the body 30 of the closure part 3.
- the magnetic devices 32A, 32B of the connecting parts 34A, 34B interact with the magnetic devices 36A, 36B on the base elements 35A, 35B and thereby hold the connecting elements 34A, 34B magnetically in the initial position.
- 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).
- closure parts 2, 3 are (approximately) brought closer to one another along the closing direction X, as can be seen from Fig. 3A to 3E, 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 face 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.
- the connecting elements 34A, 34B are moved from the starting position according to Fig. 3A to 3E in the direction of a functional position relative to the body 30 of the closure part 3, as can be seen from Fig. 4A to 4E.
- the connecting elements 34A, 34B are thus adjusted on the guide parts 31A, 31B and thereby moved out of the body through openings 302A, 302B in the surface 300. 30 extended so that the connecting elements 34A, 34B protrude with their heads 343 relative to the surface 300 of the body 30.
- the connecting elements 34A, 34B are guided via the engagement elements 342 on the collar 341 of the adjustment body 340 of the respective connecting element 34A, 34B on guide tracks 310 of the respectively associated guide part 31A, 31B in such a way that the connecting elements 34A, 34B execute a forced movement relative to the body 30 when transferred from the starting position in the direction of the functional position.
- the connecting elements 34A, 34B do not move in a straight line along the closing direction X out of the guide parts 31A, 31B, but are rotated about an associated axis of rotation D along an adjustment direction V on the respectively associated guide part 31A, 31B when transferred in the direction of the functional position.
- the guide tracks 310 in the form of radially inwardly projecting, helically extending guide sections, have the effect, in the manner of a thread, that when rotating about the axis of rotation D along the adjustment direction V, the connecting elements 34A, 34B are also adjusted in superimposed movement along the closing direction X relative to the body 30 and are thus transferred in the direction of the functional position in which the connecting elements 34A, 34B protrude with their heads 343 from the surface 300 of the body 30 in the direction of the closure part 2.
- 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 Fig. 4C.
- the closure parts 2, 3 are now displaced relative to one another along the insertion direction Y, which extends transversely to the closing direction X, so that the connecting elements 34A, 34B run into the receiving openings 211A, 211B along the insertion direction Y, as can be seen from Fig. 5A to 5E.
- 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 and the form-fitting section 344 axially adjoining the respective head 343 engages between the associated edge sections 212, as can be seen in the transition from Fig. 5A to 5E to Fig. 6A to 6E.
- 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.
- 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.
- a locking device 24 is arranged on the body 20 of the closure part 2, which has a locking element 240 that is adjustable transversely to the insertion direction Y and transversely to the closing direction X on the body 20 and is spring-loaded relative to the body 20 via a spring element 242.
- the locking element 240 engages with a locking lug 241 in the area of the receiving opening 211 B, so that the connecting element 34B slides with its head 343 onto the locking lug 241 when inserted into the receiving opening 211 B, pushes it aside and thus passes the locking element 240, as can be seen in the transition from Fig. 5A-5E to Fig. 6A-6E.
- the closure device 1 In the closed position shown in Fig. 6A to 6E, the closure 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.
- the pre-tensioning 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 during the magnetically induced adjustment of the connecting element 34A, 34B from the starting position towards the functional position and is elastically tensioned.
- the pre-tensioning elements 33A, 33B cause the respective connecting element 34A, 34B to not yet be completely transferred into a rotational position associated with the functional position by the magnetic interaction of the magnetic devices 22A, 22B, 32A, 32B, but rather a slight residual angle remains, as can be seen from Fig. 4A-4E and 5A-5E.
- the connecting elements 34A, 34B with their form-fitting sections 344 engage in a form-fitting manner between the edge sections 212 of the receiving openings 211A, 211B when the closure device 1 is in the closed position according to Fig. 6A to 6E, the connecting elements 34A, 34B are locked in their rotational position relative to the body 20 of the closure part 2 and thus also relative to the body 30 of the closure part 3.
- the closure parts 2, 3 are fixed in position relative to one another in the closed position by the arrangement of two connecting elements 34A, 34B. Because the connecting elements 34A, 34B are locked in their rotational position, the connecting elements 34A, 34B in particular cannot rotate back against the adjustment direction V relative to the guide parts 31A, 31B and are thus fixed in the extended functional position relative to the body 30.
- Connecting elements 34A, 34B are extended slightly further along the closing direction X relative to the body 30 against the pre-tension of the pre-tensioning elements 33A, 33B and the pre-tensioning elements 33A, 33B are thus tensioned.
- pre-tensioning the pre-tensioning elements 33A, 33B play is eliminated and rattling is prevented in the closed position.
- the connecting elements 34A, 34B are thus fixed in their position relative to the body 30 of the closure part 3. This means that the connection between the closure parts 2, 3 is independent of whether the bodies 20, 30 of the closure parts 2, 3 touch each other in the closed position. Rather, the connection is established solely via the connecting elements 34A, 34B and their engagement in the engagement device 21, with the surface 300 of the body 30 of the closure part 3 facing the body 20 of the closure part 2, as can be seen, for example, from the sectional views according to Fig. 6C and 6E.
- 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.
- 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.
- a user can, for example, act manually on the locking device 24 and adjust the locking element 240 so that the locking lug 241 is removed from the area of the receiving opening 211 B transversely to the insertion direction Y, so that the connecting elements 34A, 34B can be pushed out of the receiving openings 211A, 211 B along the insertion direction Y and the closure device 1 can thus be opened.
- an electrical connector part 23 is arranged on the body 20 of the closure part 2, which is located at one end of the receiving opening 211 B.
- an associated mating connector part 37 is arranged on the adjustment body 340 of the connecting element 34B. In the functional position of the connecting element 34B, the mating connector part 37 assumes a position opposite the connector part 23, so that when the connecting element 34B is inserted along the insertion direction Y into the associated receiving opening 211 B, the connector parts 23, 37 engage with one another in a plug-in manner and thus an electrical connection is established between the connector parts 23, 37.
- the connector parts 23, 37 can, for example, form an electrical connector via which data signals are transmitted and/or an electrical supply can be provided.
- a connector can implement a USB connector, for example a USB-C connector.
- the surface 300 of the body 30 of the closure part 3 is curved, wherein in the open position of the closure device 1, shown in Fig. 8A to 8F, the heads 343 of the connecting elements 34A, 34B in the openings 302A, 302B are flush with the surface 300 and thereby take up and continue the curved shape of the surface 300.
- the guide parts 31A, 31B are formed integrally with the body 30.
- 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, in Fig. 9E in the transition to Fig. 10E.
- the connecting elements 34A, 34B are thus rotated in opposite directions to one another, whereby the slope of the opposing guide tracks 310 on the guide parts 31A, 31B is the same in amount and thus the connecting elements 34A, 34B are extended the same distance along the closing direction X.
- the guide tracks 310 on the guide parts 31A, 31B are formed by guide sections that project radially inwards and are shaped like threaded sections, which force the connecting elements 34A, 34B into a helical movement when they are transferred in the direction of the functional position, due to which the connecting elements 34A, 34B are adjusted axially along the closing direction X in a superimposed manner and also can be rotated around the respective assigned axis of rotation D pointing along the closing direction X.
- the adjustment movement of the connecting elements 34A, 34B is guided along the entire adjustment path from the starting position in the direction of the functional position along helical guide tracks 310.
- each connecting element 34A, 34B is moved linearly along the closing direction X until the engagement elements 342 interact with the guideways 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 guideways 310 in accordance with a helical movement.
- 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.
- a locking device of the type described can be used to connect any number of assemblies to one another.
