  • the first magnet device and the second magnet device are designed, when the first locking part and the second locking part to interact with each other in a magnetically attractive manner in order to transfer the connecting element from the initial position along the linear direction 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.

  • the connecting element does not protrude significantly from a surface when not in use, in order to avoid possible injury or To avoid any impairment of users.
  • there is also an aesthetic advantage when not in use, as designed surfaces in a variety of applications are not interrupted by locking elements when the locking device is not in use, but have the added value of an integrated locking solution when in use.
  • 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.
  • the engagement device has an attachment section and a receiving opening adjoining the attachment section along an insertion direction pointing transversely or obliquely to the linear direction, wherein the connecting element can be attached to the attachment section in the functional position for closing the closure device and, after being attached to the attachment section, can be pushed into the receiving opening in the insertion direction in order to transfer the closure device into the closed position.
  • 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). In another embodiment, 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 is preferably carried out linearly, for example along an adjustment direction pointing along the linear direction.
  • the engagement device has an attachment section to which the connecting element can be attached in the functional position for closing the closure device.
  • the attachment section is followed by a receiving opening which extends from the attachment section along an insertion direction pointing transversely or obliquely to the linear direction and into which the connecting element can be pushed in the insertion direction after being attached to the attachment section in order to transfer the closure device into the closed position.
  • the closure device is thus closed in such a way that the connecting element is first attached to the attachment section, for example along the linear direction, and then pushed transversely or obliquely to the linear direction into the receiving opening adjoining the attachment section. In the closed position, the connecting element is in positive engagement with the receiving opening, for example, so that the closure parts are held together.
  • the attachment section is formed, for example, by an insertion opening into which the connecting element can be inserted in the functional position to close the closure device.
  • the attachment section can also be formed by a (not further limited) surface to which the connecting element can be attached in the functional position and from which the connecting element can be pushed into the receiving opening.
  • an insertion opening forming an attachment section is circumferentially limited and defines a space into which the connecting element can be inserted.
  • the only important thing is that the connecting element in the functional position for closing the locking device is attached to the attachment section. and from there pushed into the receiving opening in the insertion direction.
  • 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 significantly outwards and is therefore not a hindrance and also does not impair the aesthetic external impression of the associated assembly.
  • the first closure part 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 one or more engagement projections, each forming an undercut, which engage with the engagement device in the closed position, so that the connecting element engages the engagement device in a form-fitting manner with respect to the linear direction.
  • the second body of the second closure part forms a surface which, in the closed position, faces the first closure part, wherein the head is substantially flush with the surface in the initial position and is spaced from the surface along the linear direction in the functional position.
  • the connecting element is thus in the body of the second Closure part is accommodated 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 essentially flush with the surface.
  • the second closure part therefore 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 connecting element should not protrude outwards by more than 25 mm relative to the surface when the connecting element is in the starting position.
  • the connecting element When the closure parts approach each other to close the closure device, the connecting element is transferred from the functional position to the starting position and, in the functional position, protrudes towards the surface along the linear direction.

  • the first magnet device is arranged on the first body of the first closure part in the region of the attachment section, for example in the region of the insertion opening forming the attachment section, and is designed to 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 towards the attachment section, for example into the insertion opening forming the attachment section, due to the magnetic attraction.
  • the first magnet device can be arranged on a base of the attachment section, for example the insertion opening forming the attachment section, so that the connecting element is magnetically drawn along the linear direction towards the attachment section by magnetic interaction with the second magnet device on the connecting element of the second closure part.
  • 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.
  • a positive engagement or a positive connection is understood to mean that the closure parts are caught together in relation to the linear direction 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 along the linear direction, at least not without removing the positive connection.
  • the positive connection can have play.
  • Surfaces of engagement projections that are in engagement with each other can also be bevelled or curved in relation to the linear direction, for example, be spherical.

  • 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 element and the engagement device.
  • the first closure part has a locking device that is designed to act on the connecting element to block or impede 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 made difficult or blocked by the locking device.
  • 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 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 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 locking element is mounted on the body of the first closure part in a tiltable manner.

  • the actuating element can be displaced linearly on the body.
  • the actuating element acts on the locking element of the locking device and moves the locking element out of the locking position so that the closure device is unlocked and the second closure part can thus be moved out of the area of the receiving opening.
  • the actuating element can be moved along an actuating direction on the body, for example longitudinally, transversely or obliquely relative to the insertion direction.
  • the actuating element can be designed, for example, as a pusher element that can be moved, for example, longitudinally, obliquely or transversely to the insertion direction in order to act on the locking element and to adjust the locking element out of the area of the receiving opening in such a way that the connecting element of the second locking part and can be moved out of the receiving opening against the direction of insertion.

  • the actuating element moves the locking device.
  • the force can be transmitted by force redirection, if the actuating direction of the actuating element is different from the direction of movement of the locking device.
  • the actuating element can also be designed to move the locking device with it, if the actuating direction of the actuating element is the same as the direction of movement of the locking device.
  • the locking element of the locking device on the body of the first closure part can be tilted, so that the locking element is moved out of the area of the receiving opening and the connecting element is thus unlocked.
  • the connecting element has a form-fitting section which, in the closed position, is rotationally engaged with the first closure part.
