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.
  • first closure part and the second closure part can be placed against one another along a closing direction.
  • the first closure part and the second closure part are locked together by the connecting element.
  • the lock can be released so that the first closure part and the second closure part can be separated from one another.
  • 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 one another, in order to magnetically assist the closing of the closure device.
  • 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 in an initial position in a housing of the other closure part received so that the engagement elements do not protrude outwards from the housing or only protrude insignificantly in the initial position. 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 for connecting the closure parts.
  • 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.
  • 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.
  • 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 connecting element can be rotated relative to the second body about an axis of rotation pointing along the closing direction.
  • the connecting element can be attached to the engagement device in a first rotational position to close the closure device and, after attachment, can be transferred from the first rotational position to a second rotational position that is different from the first rotational position, so that in the closed position the second closure part is locked by the connecting element in the second rotational position relative to the first closure part.
  • the locking parts of the locking device are brought closer together along the closing direction.
  • the locking parts can be brought closer together with magnetic support from the magnetic devices of the locking parts, which magnetically attract each other when the locking device is closed and thus draw the locking parts towards each other.
  • the connecting element on the second body of the second closure part is in the first rotational position, in which the connecting element can be placed on the engagement device, for example inserted into an opening in the engagement device.
  • the connecting element can be moved from the first rotational position to the second rotational position, so that the closure parts are locked together via the connecting element and its engagement in the engagement device.
  • the closure parts are thus held together by the engagement of the connecting element in the engagement device, and the closure parts can be released from one another by releasing the lock by returning the connecting element from the second rotational position to the first rotational position.
  • the connecting element has a bearing shaft that is rotatably mounted on the second body.
  • the connecting element is rotatably mounted on the body of the second closure part about the axis of rotation pointing along the closing direction.
  • the connecting element can be attached to the engagement device of the first closure part to close the closure device.
  • the second locking part can (only) be attached to the first locking part when the connecting element is in the first rotational position.
  • the connecting element can be moved from the first rotational position to the second rotational position in order to lock the locking parts together in this way.
  • the connecting element is (axially) movable along the closing direction between an initial position and a functional position relative to the second Body is adjustable and, in the functional position, viewed along the closing direction, projects relative to the second body, so that the connecting element for locking the first closure part and the second closure part together can be brought into engagement with the engagement device.
  • the second magnetic device which is assigned to the second closure part, is arranged on the connecting element.
  • the first magnetic device and the second magnetic device are designed to interact in a magnetically attractive manner when the first closure part and the second closure part approach each other in order to transfer the connecting element from the starting position into the functional position.
  • the closure parts of the closure device are brought closer together in the closing 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 the closing direction and can thus be brought into engagement with the engagement device on the first closure part.
  • 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 closing direction.
  • the connecting element assumes the first rotational position relative to the second body in the starting position. If the connecting element is in the starting position, the connecting element is in the first rotational position, in which it is possible to attach the connecting element to the engagement device of the first closure part.
  • the connecting element is rotatable about the axis of rotation relative to the second body after being transferred into the functional position in order to transfer the connecting element from the first rotational position into the second rotational position.
  • the connecting element If the connecting element is moved from the starting position to the functional position when the locking parts approach each other to close the locking device, the connecting element initially (continues to) assume the first rotational position and can thus be attached to the engagement device of the first locking part. Once the connecting element has been attached to the engagement device, the connecting element can be moved from the first rotational position to the second rotational position in order to lock the locking parts together.
  • the closing process takes place in different phases.
  • the closure parts are placed together when the connecting element is in the first rotational position, so that the connecting element is attached to the engagement device in a magnetically supported manner.
  • the closure parts approach each other and thus the connection element is attached to the engagement device along the closing direction. If the connecting element is attached to the engagement device and, for example, the bodies of the closure parts lie against each other with surfaces facing each other, the connecting element can be rotated about the axis of rotation pointing along the closing direction relative to the body of the second closure part in order to lock the closure parts together and thus complete the closing process. Only after the connecting element has been moved from the first rotational position to the second rotational position after being attached to the engagement device about the axis of rotation are the closure parts locked together and thus fixed to each other in the closed position of the closure device.
  • the connecting element for closing the locking device can be manually moved by a user from the first rotational position to the second rotational position, so that the locking is manually established by a user after the locking element has been attached to the engagement device.
  • the locking can also take place automatically after the connecting element has been attached to the engagement device by moving the connecting element from the first rotational position to the second rotational position.
  • the second closure part can have a tensioning element that is designed to pre-tension the connecting element in the direction of the second rotational position. Before the connecting element has been attached to the engagement device, the connecting element is held in the first rotational position. As soon as the connecting element has been attached to the engagement device, the tensioning element is released and thus, due to the pre-tension, transfers the connecting element from the first rotational position to the second rotational position.
  • the connecting element can be magnetically transferred from the first rotational position to the second rotational position when the connecting element has been attached to the engagement device, for example in that the first magnetic device and the second magnetic device each point towards each other with a plurality of poles offset in a plane extending perpendicular to the axis of rotation and interact in a multi-pole manner such that an axial and also rotational force effect with respect to the axis of rotation exists between the magnetic devices.
  • the connecting element can be held mechanically or magnetically in the first rotational position when the locking device is open.
  • the connecting element is held in the first rotational position against the prestressing force of the prestressing element.
  • the connecting element can be latched relative to the body of the second closure part or mechanically locked in some other way, for example by being positively received in an engagement section formed on the second body.
  • the connecting element is placed on the engagement device, the mechanical hold is released, so that the connecting element can be automatically transferred from the first rotational position to the second rotational position, for example due to a spring-mechanical or magnetic preload.
  • the connecting element is held magnetically in the first rotational position when the closure device is opened, for example, magnetic devices on the body of the second closure part and on the connecting element work together magnetically.
  • the second closure part can have a third magnetic device arranged on the second body of the second closure part, which is designed to work together magnetically with a fourth magnetic device of the locking element for holding the connecting element relative to the second body when the closure device is open.
  • the connecting element is thus held magnetically axially and/or rotationally in position when the closure device is open. and can thus be used to close the locking device on the engagement device of the first locking part.
  • the magnetic hold is removed, for example by superimposing other magnetic forces, so that the connecting element can be transferred from the first rotational position to the second rotational position, for example due to a spring-mechanical or magnetic preload, in order to lock the locking parts together.
  • the third magnetic device is arranged on the body of the second closure part.
  • the fourth magnetic device in contrast, is arranged on the connecting element.
  • the fourth magnetic device can be formed by the second magnetic device or by an additional magnetic device on the connecting element that is separate from the second magnetic device.
  • the second closure part has an actuating element that can be actuated by a user, which is operatively connected to the connecting element and can be actuated to rotate the connecting element. If the transfer of the connecting element from the first rotational position to the second rotational position does not occur automatically when the closure parts are placed against one another, a user can act on the connecting element via the actuating element to rotate it. Conversely, a user can act on the actuating element to rotate the connecting element from the second rotational position to the first rotational position and thus release the lock to open the closure device.
  • the actuating element can, for example, be designed as a lever element protruding outward from the body of the second closure part.
  • the actuating element can be connected directly to the connecting element. In another embodiment, however, the actuating element can also be operatively connected to the connecting element, for example through an intermediate gear, for example a pinion gear or a lever gear.
  • the engagement device has an opening formed on the first body into which the connecting element can be inserted.
  • the connecting element is inserted into the opening and, after insertion into the opening, can be transferred from the first rotational position to the second rotational position in order to lock the closure parts together in this way.
  • the opening has a limiting section that limits the opening circumferentially.
  • the shape of the opening defined by the limiting section is such that the connecting element can be inserted into the opening in the first rotational position and, after turning from the first rotational position to the second rotational position after inserting the connecting element into the opening, engages behind the limiting section with respect to the closing direction, so that the connecting element fixes the closure parts to one another along the closing direction.
  • the opening has a non-rotationally symmetrical shape in a plane perpendicular to the axis of rotation.
  • the opening into which the connecting element is inserted to close the locking device therefore deviates from a circular shape and is not rotationally symmetrical.
  • the (non-rotationally symmetrical) shape of the opening is basically arbitrary.
  • the opening can be approximately triangular, square or otherwise regular or irregular, for example polygonal.
  • the opening has a cross shape.
  • the opening has the shape of an elongated hole.
  • the second closure part has an engagement section formed on the second body, which engages in the opening after the connecting element is attached to the engagement device.
  • the engagement section protrudes, for example, from a surface of the second body, which faces the first body when the closure parts are attached to one another, in the direction of the closing direction.
  • the engagement section formed in a fixed manner on the second body is introduced into the opening on the body of the first closure part when the closure parts are attached to one another and is accommodated in the opening in the closed position, for example in a rotationally fixed manner with respect to the axis of rotation.
  • the connecting element is adjustable between a starting position and a functional position, for example linearly along the closing direction relative to the body of the second closure part, the connecting element can be accommodated in the starting position, for example, within the engagement section.
  • the connecting element is adjusted relative to the engagement section and in the functional position protrudes outwards along the closing direction relative to the engagement section.
  • the first closure part has an adjustment part which, when the closure device is open, is arranged in the opening such that the adjustment part at least partially closes the opening.
  • the adjustment part can be adjusted out of the opening so that the opening is exposed and the connecting element of the second closure part can be inserted into the opening on the first closure part.
  • the adjustment part can, for example, be substantially flush with an outward-facing surface of the body of the first closure part, so that the opening is closed to the outside and, for example, no dirt can penetrate into the interior of the body of the first closure part.
  • the aesthetics of the first closure part can be improved by such an adjustment part when the closure device is open.
  • essentially flush means that no sharp-edged areas of the adjustment part protrude from the surface of the body of the first closure part.
  • the adjustment part should not protrude more than 25 mm outwards relative to the surface when the adjustment part closes the opening of the body of the first closure part when the closure device is open.
  • the adjustment part is guided on the first body so as to be linearly displaceable along the closing direction. If the closure parts are brought closer together to close the closure device, the adjustment part is adjusted out of the opening and is linearly displaced on the body of the first closure part.
  • the adjustment part can, for example, be held mechanically or magnetically in position on the body of the first closure part when the closure device is open, such that the adjustment part is arranged in the opening and thus at least partially closes the opening to the outside.
  • a mechanical hold can, for example, be provided by a spring element that pre-tensions the adjustment part relative to the body of the first closure part.
  • a magnetic hold can, for example, be provided by magnetic devices that have a magnetically attractive effect between the body of the first closure part and the adjustment part and thereby hold the adjustment part magnetically in the opening.
  • the adjustment part In the closed position of the locking device, the adjustment part is adjusted out of the opening. If the locking device is opened again, the adjustment part can be automatically adjusted back into the opening by pre-tensioning a mechanical spring or by magnetic pre-tensioning of magnetic devices acting between the adjustment part and the first body, so that the adjustment part again at least partially closes the opening.
  • 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 engages, for example, in an opening of the engagement device of the first closure part and engages behind a limiting section delimiting the opening, 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 closing direction.
  • a positive engagement or a positive connection is understood to mean that the closure parts are caught together in relation to the closing 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 closing 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 closing direction, for example with a spherical shape.
  • the head has a non-rotationally symmetrical shape in a plane perpendicular to the axis of rotation.
  • the shape of the head viewed along the plane perpendicular to the axis of rotation, can correspond to the shape of the opening, so that the head and the opening of the engagement device are complementary to one another and the head can be inserted into the opening of the engagement device of the first closure part in the first rotational position.
  • 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, 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 magnetic attraction between the Magnetic devices 24, 212 ensure that the adjustment part 21 is held in engagement with the opening 201 when the closure direction 1 is open, as can be seen from Fig. 6F is evident.
  • the connecting element 34 with the head 343 does not engage in the engagement section 301 when the closure device 1 is open, but lies axially along the closing direction X on the engagement section 301, as can be seen from Fig. 6A-6G
  • the clamping element 35 represents, in contrast to the embodiment according to Fig. 1A-1D to 4A-4H , a clamping force in the direction of the first rotational position of the connecting element 34, which the connecting element 34 assumes when the closure device 1 is open, so that the connecting element 34 is held in the position according to Fig. 6A to 6G is held.
  • the connecting element 34 and the engagement section 301 on the body 30 are inserted into the opening 201 in the area of the surface 200 of the body 20 of the closure part 2, as can be seen from Fig. 7A to 7G
  • the adjusting part 21 is thereby pushed along the closing direction X into the body 20.
  • the magnetic devices 22, 32 on the housing part 202 of the body 20 and on the connecting element 34 are brought closer together, so that the magnetic attraction force between the magnetic devices 22, 32 causes an axial adjustment of the connecting element 34 along the closing direction X and the connecting element 34 is drawn into the interior 203 of the body 20, as can be seen from Fig. 8A to 8G
  • the magnetic devices 22, 32 are each designed to be multi-pole and provide a magnetic attraction force not only linearly along the closing direction X, but also rotationally around the axis of rotation D pointing along the closing direction X, so that due to the magnetic interaction between the magnetic devices 22, 32, the connecting element 34 is rotated about the axis of rotation D and into the locking position according to Fig. 8F and 8G is brought.
  • the locking parts 2, 3 are locked together via the connecting element 34.
  • the connecting element 34 is rotated into the second rotational position and is therefore no longer congruent with the opening 201 of the body 20, so that the head 343 of the connecting element 34 engages behind an edge section 206 which circumferentially delimits the opening 201.
  • the closure parts 2, 3 are thus locked together in the closed position of the closure device 1.
  • the connecting element 34 and the rotary element 33 are connected to one another in a rotationally fixed manner about the rotation axis D, but can be moved axially relative to one another.
  • the rotary element 33 remains axially in position on the body 30 when the connecting element 34 is axially adjusted when the locking direction 1 is closed, while the connecting element 34 is adjusted along the closing direction X relative to the body 30 and is drawn into the interior 203 of the body 20 of the locking part 2 in order to be able to lock the locking parts 2, 3 together.
  • the actuating element 36 engages in an opening 333 on the shaft 330 of the rotary element 33 and is thereby firmly connected to the rotary element 33.
  • the actuating element 36 passes through an elongated hole opening on the bearing shaft 340 of the connecting element 34 (see Fig. 7F ), so that the connecting element 34 is fixed in a rotationally fixed manner to the rotary element 33, but is axially adjustable relative to the rotary element 33 and also relative to the actuating element 36 which is fixedly arranged on the rotary element 33.
  • the actuating element 36 lies in the opening 304 on the body 30, which extends in an arc around the axis of rotation D, and is adjustable in the opening 304.
  • the head 343 of the connecting element 34 has a cross shape.
  • the connecting section 301 on the body 30 and the opening 201 on the body 20 are also shaped in a complementary manner.
  • the connecting section 301 with the head 343 of the connecting element 34 received therein can be introduced into the opening 201, wherein to close the closure device 1, the head 343 is pulled into the interior of the housing 20 and rotated relative to the body 20. In the embodiment shown, the rotation takes place by approximately 45°.
  • Fig. 10A, 10B In the embodiment shown, the head 343 of the connecting element 34 has an elongated shape and rests on the engagement portion 301 on the body 30, as can be seen from Fig. 10A
  • the axis of rotation D, around which the connecting element 34 is rotatable, is not centric to the head 343, but is offset downwards, as can be seen from Fig. 10A is evident.
  • the opening 201 on the body 20 is formed as an elongated hole complementary to the shape of the head 343.
  • the head 343 and the engagement section 301 of the closure part 3 can thus be brought into engagement with the opening 201, displacing an adjustment part 21 arranged in the opening 201.
  • the head 343 After the head 343 has been inserted into the opening 201, it can be rotated about the axis of rotation D in order to lock the closure parts 2, 3 together, analogously to what has been described above.
  • the connecting element 34 is not axially adjustable to the body 30 of the closure part 3, but can only be rotated about the axis of rotation D.
  • the connecting element 34 is not axially adjustable to the body 30 of the closure part 3, but can only be rotated about the axis of rotation D.
  • a locking device of the type described can be used, for example, in a vehicle, for example to lock objects, such as electrical or electronic devices to a vehicle seat or other vehicle component.
  • a locking device of the type described can be used to connect any number of assemblies to one another.
