Definitions

  • the invention relates to a closure device according to the preamble of claim 1.
  • Such a closure device is used to connect two assemblies to one another, for example as a closure for containers, bags, items of clothing, helmets or to connect other assemblies to one another.
  • a closure device should be easy to close and easy to open again.
  • the locking device In a closed position, the locking device should provide a secure hold for the assemblies to be connected and in particular fix the assemblies so resiliently to one another that the assemblies cannot be easily separated from one another, at least not without deliberate actuation of the locking direction.
  • a closure device of this type comprises a first closure part, which has a housing part, a spring locking element which is arranged in an elastically resilient manner on the housing part and has at least one first latching section, and a first magnetic element.
  • the closure device also includes a second closure part, which has a blocking element with at least one second latching section and a second magnetic element.
  • the first closure part and the second closure part can be attached to one another in a closing direction under the magnetically attractive effect of the first magnetic element and the second magnetic element. In a closed position, the first latching section and the second latching section are in positive engagement with one another, so that the first closure part and the second closure part are held together counter to the closing direction.
  • the closure parts While in the closed position the closure parts are held together in a latching manner by the engagement between the spring locking element and the blocking element, the closure parts can be separated from each other by releasing the engagement between the spring locking element and the locking element.
  • two subassemblies of the closure device can be moved relative to one another by introducing an actuating force. If the form-fitting engagement between the spring locking element and the blocking element is eliminated, the closure parts can be separated from one another.
  • Such a closure device is, for example, from EP 2 040 572 B1 and the EP 2 252 176 B1 famous.
  • the object of the present invention is to provide a closure device that makes unintentional opening even more difficult.
  • the locking device has a blocking element which is designed to block a movement of the assemblies relative to one another, with the assemblies being movable relative to one another when an actuating force between the assemblies is greater than a blocking force.
  • the closure parts can be attached to one another along the closing direction with the latching sections latching in a simple, haptically comfortable manner, with the closure parts being held securely together in the closed position by latching the latching sections of the spring locking element on the one hand and the locking element on the other.
  • the closure device By moving the subassemblies of the closure device relative to one another, the closure device can be opened by disengaging the latching sections of the spring locking element on the one hand and the locking element on the other by moving the assemblies relative to one another.
  • the closure device has an inhibiting element which is designed to provide an inhibiting force for inhibiting the opening movement when there is an opening movement of the assemblies relative to one another.
  • the inhibiting element is designed in such a way that the inhibiting element inhibits the opening movement, but not (completely) blocks it, so that when the actuating force exceeds an inhibiting force between the Assemblies, the locking device can be opened by overcoming the inhibiting element.
  • the blocking element thus makes the opening process more difficult and in this way reduces the risk of the closure device being released unconsciously and unintentionally.
  • the blocking element does not block the opening movement in such a way that opening is only possible after the blocking element has been actuated (caused by an additional actuating means).
  • the form-fitting engagement between the latching sections of the spring locking element and the blocking element is canceled.
  • the relative movement of the assemblies to one another can in this case, for example, move the spring locking element relative to the blocking element.
  • the spring locking element can be spread by the relative movement of the assemblies, for example—with the spring locking element otherwise standing still—so that the form-fitting engagement is canceled in this way.
  • one of the subassemblies is assigned to the spring locking element, so that moving this subassembly moves the spring locking element relative to the locking element.
  • the spring locking element is thus moved out of engagement with the locking element, so that the connection between the closure parts is broken in this way and the closure parts can be separated from one another.
  • one of the assemblies is part of the first closure part and the other of the assemblies is part of the second closure part.
  • one of the assemblies can be realized by the first closure part as a whole and the other of the assemblies can be realized by the second closure part as a whole.
  • one of the assemblies can be realized by the housing part of the first closure part, which is to be moved to a further housing part of the first closure part in order to open the closure device.
  • the spring locking element arranged on the housing part is attached to the first closure part and thus also to the Blocking element of the second closure part moves in order to cancel the form-fitting engagement between the latching portions of the spring locking element and the locking element for opening the closure device in this way.
  • the blocking provided by the blocking element occurs during opening between the closure parts, namely between the assemblies of the closure parts to be moved for opening.
  • the blocking it is also possible for the blocking to be brought about between assemblies that are part of one of the closure parts, so that a relative movement of assemblies of one of the closure parts is blocked by the blocking element for opening.
  • both assemblies can be part of the first closure part.
  • the assemblies are moved relative to one another to open the closure device, with the blocking element acting between the assemblies and inhibiting the opening movement of the assemblies relative to one another.
  • one of the assemblies can be configured by the housing part on which the spring locking element is arranged.
  • the other of the assemblies can be implemented by a further housing part of the first closure part, relative to which the housing part of the first closure part carrying the spring locking element is to be moved.
  • the inhibiting element is arranged on one assembly and is designed to interact with the other of the assemblies when the assemblies move relative to one another.
  • the blocking element can, for example, be arranged in one piece on the assembly and interact with the other assembly during a relative movement in such a way that the other of the assemblies rubs against the blocking element, for example, and in this way a block is provided.
  • the blocking element assumes a basic position when the closure device is in the closed position.
  • the inhibition element can be deflected out of this basic position when the assemblies are moved relative to one another.
  • the deflection is not effected by an additional actuating means, but by interaction of the assemblies with one another during the opening movement, so that the inhibiting element makes the opening movement more difficult, but does not have to be actuated separately in order to allow opening.
  • the blocking element can be fully or partially elastic and thus elastically deflectable from the basic position. After the opening process has taken place, the blocking element returns to its basic position due to its elasticity, so that when it is closed again, the opening process of the closure device is again blocked.
  • the blocking element is designed to act between the assemblies when the assemblies move in a direction of movement relative to one another in such a way that one of the assemblies is adjusted transversely to the direction of movement relative to the other of the assemblies .
  • the assemblies are moved relative to one another along a direction of movement.
  • the inhibiting element acts between the assemblies and causes the assemblies to be adjusted relative to one another transversely to the direction of movement when moving along the direction of movement.
  • the inhibiting element can be in the form of an elastic element or optionally also in the form of a rigid element and can be arranged on one of the assemblies.
  • the blocking element is designed in such a way that when the assemblies move relative to one another, the other of the assemblies runs onto the blocking element and is thereby adjusted relative to one of the assemblies. In this way, for example, friction can be provided between the assemblies, which counteracts the opening movement of the assemblies relative to one another.
  • the inhibiting element is designed to adjust one of the assemblies transversely to the direction of movement relative to the other of the assemblies against a magnetic attraction force of the first magnetic element and the second magnetic element.
  • the magnetic force of attraction between the magnetic elements also acts at least between the assemblies. Because the blocking element displaces the assemblies during the opening movement against the magnetic force of attraction, a blockage is provided between the assemblies, the blocking force being determined by the force required to displace the assemblies relative to one another against the magnetic force of attraction.
  • the spring locking element and the blocking element can be moved relative to one another in order to open the closure device along an opening direction that is different from the closing direction.
  • One of the assemblies here is for example associated with the spring locking element and the other of the assemblies, for example, the locking element, so that the spring locking element and the locking element can be moved relative to each other by relative movement of the assemblies.
  • the fact that the opening direction differs from the closing direction should be understood to mean that the opening direction is not in the same direction as the closing direction and is also not directed in the opposite direction to the closing direction.
  • the opening direction can be directed, for example, transversely or at an oblique angle to the closing direction, so that the closure device is closed and opened in different directions.
  • closure parts are attached to one another for closing along the closing direction.
  • the blocking element of the second closure part and the spring locking element of the first closure part snap into engagement with one another while the spring locking element is pushed aside elastically, so that the blocking element is positively held on the spring locking element in the closed position counter to the closing direction.
  • the closure parts are moved towards one another along the opening direction in order in this way to disengage the latching sections from one another, preferably by moving the latching sections tangentially to one another and thus disengaging them.
  • disengagement of the locking element and the spring locking element can be achieved by a relative movement between the spring locking element and the locking element.
  • disengaging can also be brought about by force-deflecting elements that push the latching section of the spring locking element aside, as is the case, for example, in FIG EP 2 166 895 B1 is described, or by a mixed form.
  • the blocking element counteracts the opening movement of the assemblies relative to one another.
  • the inhibiting element can be arranged at very different locations in order to inhibit the opening movement.
  • the inhibiting element can be designed in particular for interaction between the first closure part and the second closure part and for this purpose can be arranged on the first closure part for interaction with the second closure part or on the second closure part for interaction with the first closure part.
  • the inhibiting element can be arranged on the housing part of the first closure part for interaction with a housing section of the second closure part or with the locking element of the second closure part.
  • the inhibiting element can be arranged on a housing section of the second closure part for interaction with a housing section of the first closure part.
  • the blocking element can also be placed between the housing part and the housing of the first closure part, so as to inhibit an opening movement of the spring locking element on the first closure part.
  • the blocking element can be arranged movably on a base of the second closure part, in which case the inhibiting element acts, for example, between the blocking element and the base of the second closure part and in this way inhibits movement of the blocking element to open.
  • the blocking element can interact between those assemblies that are to be moved towards one another in order to open the closure device, with the blocking element being designed in such a way that the blocking element enables the opening movement when the blocking force is overcome, without a separate actuation of the blocking element being necessary for this purpose.
  • the blocking element can be deflected elastically towards the housing part of the first closure part or towards the second closure part.
  • the blocking element can, for example, be designed in one piece with the housing part of the first closure part or with a base of the second closure part, for example in the form of an elastically deformable spring tongue.
  • a spring tongue can be cut free in sections from a housing section of the housing part of the first closure part or a housing section of the second closure part and can extend along the opening direction, with the blocking element being deflectable perpendicular to the opening direction with elastic deformation during the opening movement.
  • the inhibiting element is not formed in one piece, for example, with the housing part of the first closure part or with a base of the second closure part, but as an element arranged movably with respect to the housing part of the first closure part or the base of the second closure part, for example in the form of a lever element.
  • a separate blocking element can, for example, be elastically pretensioned and thus elastically deflectable.
  • the chocking element has an elastically deformable spring section and a chocking head for interacting with one of the assemblies.
  • the blocking element is arranged, for example, on the housing part of the first closure part, the blocking head can be designed to interact with the second closure part, for example with the locking element of the second closure part.
  • the arresting element is arranged on the second closure part, the arresting head can be designed to interact with the first closure part, for example a housing section of the first closure part.
  • the blocking head has a ramp on which a section of one of the assemblies runs.
  • the ramp extends, for example, obliquely to the opening direction. If the blocking element is arranged, for example, on the first closure part, for example on the housing part of the first closure part, the second closure part, for example the blocking element of the second closure part, can run onto the ramp when the closure device is opened, so that the blocking element is pushed aside and thereby providing a stopping force.
  • the blocking force can be adjusted, for example, by the angle of the ramp relative to the opening direction and by the elastic properties of the blocking element.
  • the at least one second latching section of the blocking element of the second closure part can have a run-on slope for interacting with the arresting element, particularly in a configuration in which the blocking element is arranged on the housing part of the first closure part.
  • the blocking force can be increased, in particular by the design of ramps on the blocking element and/or on a component that interacts with the blocking element, by the elastic properties of the blocking element, be adjusted by lever ratios on the blocking element and by the magnetic attraction between the magnetic elements of the closure parts.
  • the blocking force is dimensioned in such a way that unintentional opening is reliably prevented, but a user can open the closure device by overcoming the blocking force.
  • the inhibiting force can act as a breakaway force that has to be overcome for opening and after which the opening can take place comparatively easily.
  • a breakaway force can be provided, for example, by an elastically deflectable element, and after pushing aside the blocking element, the (further) opening of the closure device can take place relatively easily by moving the spring locking element and the locking element relative to one another.
  • the blocking element In a configuration in which the blocking element is arranged on the housing part (realizing one of the assemblies) of the first closure part, the blocking element (realizing the other assembly) is in contact with the blocking element in the closed position.
  • the blocking element thus already acts in the closed position essentially without play with the blocking element, so that to open the closure device during an opening movement the blocking element runs directly onto the blocking element and interacts with it.
  • the blocking element in the closed position does not interact with the blocking element arranged on the first closure part and is therefore not in contact with the blocking element in the closed position.
  • the blocking element can thus initially be moved over a certain opening path to the spring locking element until the blocking element comes into contact with the inhibiting element, with the opening path being such that the inhibiting effect of the inhibiting element begins before the form-fitting engagement of the first latching section and of the second latching section is cancelled. The opening movement is thus blocked before the closure parts are detached from one another.
  • the magnetic elements work together in a magnetically attractive manner.
  • the magnetic elements can each be formed by a permanent magnet or an arrangement of permanent magnets, the magnetic elements with unlike Point poles to each other and thus interact magnetically attractive along the closing direction.
  • one of the magnetic elements can be configured as a permanent magnet or an arrangement of permanent magnets and the other of the magnetic elements can be configured as a ferromagnetic armature and thus passively magnetic.
  • the magnetic elements when the closure device is opened, the magnetic elements are sheared off tangentially from one another by the assemblies being moved towards one another. During the opening movement, the magnetic force of attraction between the first magnetic element and the second magnetic element weakens and can even turn into repulsion from a certain opening path. This enables the closure parts to be separated easily and with a pleasant feel when the form-fitting engagement between the latching sections of the spring locking element and the blocking element is eliminated.
  • the blocking of the blocking element can start when the magnetic elements are (still) attracted to each other.
  • the inhibition can only set in when the magnetic elements interact in a repelling manner after a certain opening distance.
  • the magnetic elements work together in a magnetically attractive manner along the closing direction and thus support the attachment of the closure parts for closing the closure device.
  • closing can take place largely automatically, for example, when the closure parts are brought closer together, so that the locking element is pulled into latching engagement with the spring locking element under the magnetic effect.
  • the spring locking element can, for example, have the form of a circumferentially open C-ring on which one or more latching sections are formed, which point radially inwards, for example.
  • the locking element which in this case is for example peg-shaped, can be inserted in order to engage the locking element with the spring locking element in a form-fitting manner.
  • the spring locking element can be formed, for example, by one or more latching tongues, for example by one another opposite locking tongues, between which the locking element can be used.
  • the blocking element of the second closure part has a blocking section for blocking the opening movement.
  • the blocking element can be rotatable about the closing direction to the spring locking element between a first position and a second position, the blocking section facing the arresting element arranged on the first closure part in the first position but not facing in the second position.
  • the closure device In the first position, the closure device cannot be opened due to the interaction of the blocking section with the inhibiting element.
  • the closure device In the second position, on the other hand, the closure device can be opened by overcoming the blocking force.
  • a ramp in the area of the blocking element, for example, a ramp can be formed to run onto the blocking element, which however only faces the blocking element in the second position, so that the locking device is only opened when the blocking element is in the second position relative to the blocking element, overcoming the blocking force can be.
  • the blocking section can have a vertical flank, for example, which extends perpendicularly to the opening direction, so that the blocking section cannot interact with the inhibiting element to push it aside. If, in the first position, the blocking section faces the blocking element, the blocking element cannot be pushed aside by interacting with the blocking element, so that opening is blocked. The opening can only take place when the blocking element has been brought into the second position relative to the spring locking element.
  • the blocking element can be prestressed in the direction of the first position toward the first closure part, so that the blocking element is accommodated in a blocking manner on the spring locking element in the closed position.
  • a bias can be brought about, for example, by the magnetic elements, in that the magnetic elements automatically bring the blocking element into the first position when the closure device is closed.
  • the magnetic elements each have at least two magnetic poles, which point towards the other magnetic element, with the magnetic poles facing each other in a magnetically attractive manner in the first position, while in the second position there is magnetic repulsion between the magnetic elements, so that the Locking element when closing the closure device automatically enters the first position relative to the spring locking element.
  • prestressing can be effected, for example, by an elastic element, for example one or more spring elements.
  • a bias towards the first position can be brought about by gravity or by inclined planes.
  • the blocking element can also not be biased in the direction of the first position, so that the blocking element can only be adjusted between the first position and the second position by manual actuation by a user.
  • the inhibiting element is not necessarily designed as a mechanical element for providing a mechanical inhibiting force.
  • the blocking element can, for example, be realized by a third magnetic element, which is arranged and configured such that the third magnetic element magnetically counteracts the relative movement of the assemblies relative to one another for opening the closure device.
  • a magnetic inhibitory force is provided due to, for example, magnetic repulsion to be overcome when the assemblies are moved relative to one another to open the closure device.
  • the arresting element in the form of the third magnetic element can be arranged, for example, on the housing part of the first closure part.
  • the blocking element in the form of the third magnetic element can, for example, be offset from the first magnetic element of the first closure part in the opening direction, so that the second closure part with the second magnetic element arranged on it is brought closer to the blocking element in the form of the third magnetic element in the opening direction when the closure device is opened.
  • a repulsion between the third magnetic element on the first closure part and the second magnetic element on the second closure part must therefore be overcome.
  • FIG. 1A , 1B until 7A-7D show an exemplary embodiment of a closure device 1, which 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 first closure part 2 has a housing part 20 which, on a raised section, forms an attachment surface 200 around which a receiving groove 201 for receiving a spring locking element 21 extends.
  • the spring locking member 21 is in the form of a C-ring and is opened at a location to form an opening 212 .
  • Latching sections 211 in the form of undercuts protrude radially inwards from a spring section 210 extending in a C-shape around the closing direction X.
  • the housing part 20 forms a receiving opening 202 for receiving a magnet element 22 .
  • the receiving opening 202 is closed to the outside by a cover element 3 .
  • the housing part 20 of the first closure part 2 is held firmly between housing parts 23, 24, which are screwed together to form the closure part 2 and, for example, accommodate an assembly assigned to the closure part 2 between them, so that the housing parts 23, 24 are fixed to the assembly.
  • the housing part 23 forms an engagement opening 230 into which the second closure part 3 can be inserted in the closing direction X with a pin-shaped locking element 31 and within which the spring locking element 21 is arranged, as shown in FIG 2 is evident.
  • the housing part 23 is open in the closing direction X on the side facing the second closure part 3 to form the engagement opening 230 and is also opened laterally through an opening 231 along an opening direction Y transverse to the closing direction X.
  • the second closure part 3 has a base 30 to be fixed to an associated assembly.
  • the locking element 31 protrudes from the base 30 and forms a shaft section 310 and a latching section 311 running around the circumference of the closing direction X in the form of an undercut.
  • a magnetic element 32 is accommodated in the locking element 31 and interacts attractively with the magnetic element 22 of the first closure part 2 .
  • the first closure part 2 and the second closure part 3 can be attached to one another in the closing direction X in order in this way to bring the locking element 31 into engagement with the engagement opening 230 on the housing part 23 and thus with the spring locking element 21 arranged within the engagement opening 230.
  • the attachment is effected by magnetic attraction of the magnet elements 22, 32 in a magnetically assisted manner, so that the closure parts 2, 3 are attracted to one another when they approach one another.
  • the blocking element 31 comes into contact with a peripheral ramp 312 on the latching section 311 with the latching sections 211 on the spring locking element 21 and thereby forces the latching sections 211 aside, with radial expansion of the spring locking element 21, until the latching section 311 has moved past the latching sections 211 and the latching portions 211 snap into engagement with the latching portion 311, as in the transition from Figures 3A-3D towards Figures 4A-4D is evident.
  • the blocking element 31 rests against the attachment surface 200 of the housing part 20 in the closed position.
  • the magnetic elements 22, 32 face each other in a magnetically attractive manner.
  • a locking element 25 in the form of an elastically deflectable spring tongue formed integrally and in one piece on the housing part 20 is arranged on the housing part 20 of the first closure part 2 .
  • the arresting element 25 has, as shown in the sectional view Figure 4D As can be seen, it has an elastically deformable spring section 250 which is connected at one end to the housing part 20 and at its other, free end carries a locking head 251 which projects upwards counter to the closing direction X and on one of the locking element 31 of the second closure part 3 side facing a ramp 252 forms.
  • the blocking element 25 extends essentially along an opening direction Y, along which the blocking element 31 is to be moved relative to the spring locking element 21 in order to open the closure device 1 .
  • the blocking element 25, designed in the manner of a spring tongue, is directed in the opposite direction to the opening direction Y and points with the blocking head 251 towards the blocking element 31 received on the spring locking element 21 in the closed position.
  • the inhibiting element 25 provides an inhibition which counteracts the opening of the closure device 1 and thus makes opening more difficult.
  • the closure parts 2, 3 To open the closure device 1, the closure parts 2, 3 must be moved relative to one another in the opening direction Y, so that the blocking element 31 is moved out of the engagement of the spring locking element 21 through the opening 212 formed on the side of the C-shaped spring locking element 21.
  • the opening direction Y is essentially perpendicular to the closing direction X, so that the opening movement differs from the closing movement.
  • closure parts 2, 3 thus realize assemblies that can be moved relative to one another in order to open the closure device 1. Because the closure parts 2, 3 are moved towards one another as a whole, the spring locking element 21 and the locking element 31 are moved relative to one another and disengaged from one another, so that thereby the connection between the closure parts 2, 3 is canceled and the closure parts 2, 3 can be separated from each other.
  • the blocking element 31 When opening, the blocking element 31 is moved out of the area of the spring locking element 21, so that the latching sections 211, 311 are disengaged. During the lateral movement of the blocking element 31, the locking section 311 on the blocking element 31 runs with its ramp 312 onto the blocking element 25, so that the blocking element 25 is deflected perpendicularly to the opening direction Y (in the exemplary embodiment downwards in the direction of the closing direction X), like this in transition from Figures 4A-4D towards Figures 5A-5D is evident.
  • a force that counteracts the opening movement of the closure device 1 is required to deflect the blocking element 25 .
  • the blocking force provided in this way acts as a breakaway force in that a large force is required at the start of the opening movement in order to deflect the blocking element 25 perpendicularly to the opening direction Y as a result of the ramps 252, 312 running onto one another. If the blocking element 25 is deflected, as in Figure 5D shown, so the further opening can be done easily.
  • the blocking element 25 with the blocking head 251 in the closed position is in contact with the latching section 311 of the blocking element 31 .
  • the blocking element 25 thus counteracts the opening movement right at the start, so that the closure device 1 can only be opened by deflecting the blocking element 25 .
  • the magnetic elements 22, 32 are sheared off from one another tangentially along the opening direction Y, weakening the magnetic attraction force of the magnetic elements 22, 32.
  • the magnetic elements 22, 32 moved sufficiently far towards one another been, due to a so-called edge effect even a magnetic reversal and thus repulsion between the magnetic elements 22, 32 result, so that the closure parts 2, 3 can be easily separated from each other after the locking element 31 has been moved out of the area of the spring locking element 21.
  • a guide surface 204 is formed in the area of the lateral opening 231 of the housing part 23, which is curved in sections and is therefore inclined so that the blocking element 31 is guided along a removal direction E on the closure part 2 for easy removal from the closure part 2.
  • FIGS 7A-7D show the closure device 1 with separate closure parts 2, 3.
  • the closure device 1 is formed by two closure modules 26, 32, each of which has two closure parts 2A, 2B, 3A, 3B.
  • the closure module 26 has two first closure parts 2A, 2B on a housing 260, which can be brought into engagement with two second closure parts 3A, 3B on a body 320 of the second module 32.
  • the closure modules 26, 32 can be attached to one another in the closing direction X, as a result of which the blocking elements 31 of the second closure parts 3A, 3B on the module 32 side latch with the spring locking elements 21 of the first closure parts 2A, 2B on the module 26 side intervention, so that in the in 9A, 9B and 11A-11C illustrated closed position, the modules 26, 32 are held together.
  • the modules 26, 32 can be rotated about an axis of rotation D to each other, as in the transition from 9A, 9B towards 10A, 10B is evident.
  • the module 32 is rotatably mounted on the module 26 via a pivot pin formed on the body 320 which, in the closed position, engages in a pivot pin engagement 261 on the housing 26 of the module 26 .
  • the rotary movement synchronously removes the locking elements 31 of the closure parts 3A, 3B from the spring locking elements 21 of the closure parts 2A, 2B, so that the modules 26, 32 can be removed from one another counter to the closing direction X.
  • each first closure part 2A, 2B of the module 26 is assigned an inhibiting element 25 which inhibits the opening movement.
  • the blocking element 25 is the embodiment according to Figures 8 to 12 in this case identical to the embodiment according to 1 until 7A-7D .
  • the second closure part 3 is identical to the embodiment shown in FIG Figures 1 to 7A-7D designed.
  • a first closure part 2 has a housing 27 on which a housing part 20 is arranged in the manner of a slide so that it can be moved along an opening direction Y′, so that the spring locking element 21 on the housing part 20 is movable along the opening direction Y′ by actuating an actuating element 205 formed on the housing part 20 and designed as a push button relative to the blocking element 31 engaging in an engagement opening 271 of the housing 27 in the closed position in order to open the closure device 1.
  • the housing part 20 is pretensioned in relation to the housing 27 via a spring element 270 in the direction of a position in which the blocking element 31 can be connected to the spring locking element 21 .
  • the locking element 31 is inserted into the engagement opening 271 of the housing 27 in the closing direction X and thereby brought into engagement with the spring locking element 21 on the housing part 20, as can be seen from the sectional view in FIG Figure 15A is evident.
  • the housing part 20 is pushed via the actuating element 205 in the opening direction Y′ towards the housing 27 so that the spring locking element 21 is moved towards the blocking element 31 and disengaged from the blocking element 31 .
  • a blocking element 25 is arranged on the housing part 20, which is designed analogously to the blocking element 25 of the embodiment according to FIGS. 1 to 7A-7D. 1 to 7A-7D, the blocking element 25 counteracts the opening movement in that the blocking element 25 interacts with the blocking element 31 via the blocking head 251 and is deflected during the opening movement with elastic deformation and thereby provides an inhibition.
  • FIG. 17A, 17B illustrated embodiment which is similar in its basic structure to the embodiment of FIGS vertical flank 314 formed.
  • the blocking section 313 is used in the in Figure 17B shown position to block opening of the closure device 1.
  • the blocking element 31 is rotatable about an axis of rotation A relative to the spring locking element 21 .
  • the blocking element 31 can thus be placed between an in Figure 17B shown blocking position and in Figure 17A shown release position to the Federverrieglungselement 21 are rotated.
  • the blocking section 313 with the flank 314 formed thereon and perpendicular to the opening direction Y faces the arresting element 25, which in this exemplary embodiment is designed as a spring tongue projecting counter to the closing direction X without a ramp formed thereon.
  • the locking element 31 When closing the closure device 1 according to 17A, 17B the locking element 31 is magnetically drawn into engagement with the spring locking element 21 due to magnetic interaction between the magnetic elements 22, 32 on the closure parts 2, 3. Due to the polarization of the magnetic elements 22, 32 as they are made Figure 17B can be seen, the blocking element 31 is here in accordance with the blocking position Figure 17B brought, in opposite poles of the magnetic elements 22, 32 face each other attractively.
  • the blocking element 31 is positively engaged with the spring locking element 21 and is also blocked against opening by the blocking section 314 facing the blocking element 25 with its vertical flank 314 on the blocking element 31 .
  • the blocking element 31 is to be rotated about the axis of rotation A, which is directed along the closing direction X, with respect to the closure part 2, as is done in the transition from FIG Figure 17B towards Figure 17A can be seen, so in the release position according to Figure 17A the locking section 311 with the ramp 312 formed on it faces the blocking element 25 and the closure device 1 can thus be opened by overcoming the blocking by the blocking element 25 by moving the blocking element 31 in the opening direction Y to the closure part 2 and thus disengaging from the Spring locking element 21 is brought.
  • the arresting element 25 is designed as a spring tongue which is formed integrally on the housing part 20 of the closure part 2 .
  • this is not limiting.
  • the blocking element can also be formed at a different location on the first closure part 2 or on the second closure part 3 . If the blocking element is arranged on the first closure part 2, it acts together with the second closure part 3 to inhibit opening, for example. If, on the other hand, the blocking element is arranged on the second closure part 3, the blocking element interacts, for example, with the first closure part 2 to block the opening movement. In another embodiment is conceivable - for example, in a multi-part design of the closure parts 2, 3 as in the embodiment shown in FIG Figures 13 to 16A , 16B - that the blocking element acts between housing parts of the first closure part 2 or analogously between housing parts of the second closure part 3 and thus inhibits an opening movement on one of the closure parts.
  • the arresting element 25 is inherently elastic. However, this is also not restrictive.
  • the blocking element can also be arranged as a separate element so that it can move on an associated closure part and can be deflected.
  • the blocking element 25 is designed as a lever element which is arranged in an articulated manner about an articulation axis 253 on a housing part 23 of a closure part 2 and which is elastically pretensioned towards the housing part 23 via a tensioning device 254 .
  • the blocking element 25 is in a basic position ( 18A ) with a head toward the blocking element 31 accommodated on the housing part 23, so that at the beginning of the opening movement a comparatively large, inhibiting force is provided via the blocking element 25 due to the lever ratios.
  • the opening movement 18B, 18C
  • the blocking element 25 is deflected, the blocking force is reduced due to the changing lever ratios until the blocking element 31 can be removed from the housing part 23 .
  • the arresting element 25 on the housing part 20 is not designed as an elastically deflectable spring tongue (as in the exemplary embodiment according to Figure 1A , 1B until 7A-7D) configured, but as a rigidly formed on the housing part 20 projection element.
  • the second closure part 3 is moved in the opening direction Y relative to the first closure part 2, as a result of which the blocking element 31 with the latching section 311 formed thereon runs onto the blocking element 25 via ramps on the latching section 311 and the blocking element 25. like this in transition from Figures 20A-20C towards Figures 21A-21C is evident.
  • the second closure part 3 is thus lifted off the first closure part 2 counter to the closing direction X, namely in an adjustment direction H, against the magnetic attraction force between the magnetic elements 22, 32 of the closure parts 2 , 3.
  • the locking force provided by the locking element 25 is set by the magnetic force of attraction between the magnetic elements 22 , 32 and the shape of the ramps on the locking element 25 and on the latching section 311 .
  • the blocking force acts as a breakaway force in that a comparatively large force is required when the latching section 311 of the blocking element 31 runs onto the blocking element 25 for further movement after running on the arresting element 25 in the state according to FIG Figure 21C but then a comparatively small force for further opening of the closure device 1 is required.
  • FIG. 22 to 24A-24C illustrated embodiment is the arresting element 25, in contrast to the embodiment according to Figures 19 to 21A-21C , Formed by a further, third magnetic element in the form of a permanent magnet, which is arranged on the housing part 20 of the first closure part 2 and the magnetic element 22 is upstream in the opening direction Y, as shown, for example Figure 23B is evident.
  • the other magnetic element that implements the blocking element 25 inhibits an opening movement of the second closure part 3 in that the other magnetic element has a different pole (north pole N) towards the second closure part 3 than the magnetic element 22 (south pole S), as shown 22 is evident.
  • the magnetic elements 22, 32 of the closure parts 2, 3 face each other in a magnetically attractive manner.
  • the magnetic elements 22 , 32 point towards one another with opposite poles, so that the magnetic element 32 of the closure part 3 points with a north pole N towards the south pole S of the magnetic element 22 .
  • the closure device 1 is opened by the second closure part 3 being moved in the opening direction Y relative to the first closure part 2, as in the transition from Figures 23A-23C towards Figures 24A-24C
  • the magnetic element 32 is approached in the opening direction Y to the magnetic element realizing the blocking element 25 .
  • the magnetic element 32 of the second closure part 3 thus reaches a pole of the same name (north pole N) opposite to the magnetic element on the housing part 20 of the first closure part 2 that realizes the arresting element 25, as shown in FIG Figure 24C is evident.
  • the magnetic elements 25, 32 thus act together in a magnetically repellent manner.
  • a closure device of the type described can be used in a variety of ways to connect two assemblies to one another.
  • the closure device By inhibiting the opening movement, the risk of unintentional opening is reduced here, so that the closure device can provide a secure hold in the closed position with additional security against unintentional opening.
