CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is the United States national phase of International Patent Application No. PCT / EP2023 / 082936, filed Nov. 24, 2023, and claims priority to German Patent Application No. 10 2022 131 419.7, filed Nov. 28, 2022, the disclosures of which are hereby incorporated by reference in their entireties.BACKGROUNDTechnical Field
[0002] The disclosure relates to a closure device for interconnecting two modules.Technical Considerations
[0003] A closure device of this kind comprises a first closure part having a body, a receiving opening formed on the body, and at least one locking element that is adjustable relative to the body. The closure device further comprises a second closure part which comprises a plug portion. For closing the closure device, the plug portion can be inserted into the receiving opening. In a closed position, the plug portion engages in the receiving opening and the second closure part is locked by the at least one locking element relative to the first closure part, such that the first closure part and the second closure part are held together. For separating the first closure part and the second closure part from one another, the locking effect of the at least one locking element can be overcome and the first closure part and the second closure part can be separated from one another by removing the plug portion from the receiving opening.
[0004] In the case of a closure device known from WO 2022 / 152418 A1, closure elements of a closure part are pivotable relative to a base element of the closure part, in order to act on an engagement element of a further closure part in a closed position and to thereby interconnect the closure parts.SUMMARY
[0005] An object underlying the proposed solution is providing a closure device which allows for a comfortable possibility of fixing the closure parts on one another, with reliable holding of the closure parts together in the closed position.
[0006] This object is achieved by a closure device having features as described herein.
[0007] According thereto, the at least one locking element comprises a first locking portion and a second locking portion. The second closure part comprises a first engagement device and a second engagement device. In the closed position, the locking element assumes a locking position relative to the body of the first closure part, in which the first locking portion is in engagement with the first engagement device, and the second locking portion is in engagement with the second engagement device. For overcoming the locking effect of the at least one locking element, the first locking portion can be brought out of engagement with the first engagement device and / or the second locking portion can be brought out of engagement with the second engagement device.
[0008] The at least one locking element that is arranged adjustably on the body of the first closure part serves to lock the second closure part relative to the first closure part in the closed position. For this purpose, the locking element comprises a first locking portion and a second locking portion which are spatially and functionally separated from one another and engage in associated engagement devices on the second closure part when the closure device is in the closed position. By the engagement of the first locking portion into the first engagement device and of the second locking portion into the second engagement device, the second closure part is locked on the first closure part, such that the plug portion is held in engagement with the receiving opening and the closure parts cannot be separated from one another, at least not without overcoming the locking effect.
[0009] The overcoming of the locking effect for opening the closure device can be achieved in that the first locking portion can be brought out of engagement with the first engagement device and / or the second locking portion can be brought out of engagement with the second engagement device. At least an engagement between the first locking portion and the first engagement device or between the second locking portion and the second engagement device must therefore be overcome in order to overcome the locking effect. If the engagement of at least one locking pairing, e.g., between the first locking portion and the first engagement device or between the second locking portion and the second engagement device, has been overcome, then the second closure part can be moved relative to the first closure part, at least along one spatial direction, such that the plug portion can be brought out of engagement with the receiving opening along the spatial direction and the closure parts can thus be released from one another.
[0010] The first closure part can comprise one or more, for example two, locking elements, which are arranged adjustably on the body of the first closure part. In this case, each locking element can comprise two locking portions which are in engagement with associated engagement devices of the second closure part in the closed position. In the case of an arrangement of a plurality of locking elements, even only one locking element may comprise two locking portions.
[0011] Compared with existing solutions, a closure device of the type described can offer the advantage that a fixation and separation can exist in different spatial directions, and in this case the fixation is magnetically assisted. A closure device of the type described here can be used for connecting straps, belts and harnesses on safety equipment or as a closure on bags, textiles, clothing, shoes or also watches, electronic devices, jewelry or the like.
[0012] In one non-limiting embodiment, the plug portion can be inserted into the receiving opening along a first spatial direction and along a second spatial direction perpendicular to the first spatial direction. The plug portion can thus be inserted into the receiving opening not only exclusively along a single spatial direction, but rather along a first spatial direction and along a second spatial direction perpendicular to the first spatial direction, or a movement that is oblique to the first spatial direction and to the second spatial direction and is made up vectorially by movement vector components along the first spatial direction and the second spatial direction. Furthermore, a fixing of the plug portion into the receiving opening may also be possible by a rotational movement, for example about a third spatial direction perpendicular to the first spatial direction and to the second spatial direction. The plug portion can thus be inserted into the receiving opening in a variable manner by very different movements, such that the closure parts can be interconnected in a variable manner by different movements.
[0013] In one non-limiting embodiment, in the closed position the plug portion is locked in the receiving opening both along the first spatial direction and along the second spatial direction by the engagement of the first locking portion in the first engagement device and the engagement of the second locking portion in the second engagement device. The locking effect of the at least one locking element is therefore such that in the closed position the closure parts are spatially fixed relative to one another and are thus held together in a manner fixed in location and position, in particular also non-rotatably. Since the locking portions of the at least one locking element of the first closure part engage in the engagement devices, a relative movement between the closure parts along the first spatial direction and along the second spatial direction and also along an oblique direction made up by movement vector components along the first spatial direction and the second spatial direction, as well as a rotational movement, is blocked.
[0014] In one non-limiting embodiment, the engagement of the first engagement portion with the first engagement device blocks a relative movement of the first closure part and of the second closure part relative to one another both along the first spatial direction and along the second spatial direction. In one non-limiting embodiment, the engagement of the first engagement portion with the first engagement device thus results in a locking effect both along the first spatial direction and along the second spatial direction, or an oblique direction made up vectorially by movement vector components along the first spatial direction and the second spatial direction. For example, in this case, the engagement of the first engagement portion with the first engagement device does not block or only insufficiently blocks a rotational relative movement of the first closure part and of the second closure part for example about a third spatial direction perpendicular to the first spatial direction and to the second spatial direction.
[0015] In one non-limiting embodiment, the engagement of the second engagement portion with the second engagement device blocks a relative movement of the first closure part and of the second closure part relative to one another along the second spatial direction, but not along the first spatial direction. The locking effect of the engagement of the second engagement portion with the second engagement device in the closed position of the closure device thus acts along the second spatial direction but not along the first spatial direction. For example, the locking effect of the engagement between the second engagement portion of the at least one locking element and the second engagement device serves to block a rotational movement of the closure parts relative to one another about the third spatial direction, such that due to the joint locking effect of the engagement of the first engagement portion with the first engagement device and of the second engagement portion with the second engagement device the closure parts are fixed relative to one another in a manner fixed in location, in particular also non-rotatably, when the closure device is in the closed position.
[0016] In one non-limiting embodiment, an adjustment plane is spanned by the first spatial direction and a third spatial direction that is perpendicular to the first spatial direction and to the second spatial direction. For example, for overcoming the locking effect of the at least one locking element, the first locking portion can be brought out of engagement with the first engagement direction, in the adjustment plane, and / or the second locking portion can be brought out of engagement with the second engagement device, in the adjustment plane. Thus, the locking engagement can be overcome by a relative movement between the respective engagement portion of the at least one locking element and the associated engagement device of the second closure part, such that the locking effect of at least one locking pairing is released, and thus by releasing the locking effect a relative movement of the closure parts relative to one another at least along one spatial direction, for example along the first spatial direction, along the second spatial direction, along an oblique direction, or along a rotational direction, is released.
[0017] In one non-limiting embodiment, the second closure part comprises a base portion, which protrudes relative to the plug portion, transversely to the first spatial direction. The base portion thus extends transversely to the first spatial direction, in particular along the third spatial direction. The plug portion extends from the base portion along the first spatial direction, such that the plug portion can be inserted into the receiving opening on the body of the first closure part for closing the closure device, but in the process the base portion comes to rest outside of the receiving opening, on the body of the first closure part.
[0018] In one non-limiting embodiment, the second engagement device, with which the second locking portion of the at least one locking element is in engagement in the closed position of the closure device, is formed on the base portion. The second engagement device can for example be formed as an engagement opening, with which the second locking portion of the at least one locking element is in engagement in the closed position. The engagement can be configured such that in particular a relative movement of the second locking portion relative to the second engagement device along the second spatial direction is blocked.
[0019] In one non-limiting embodiment, the first engagement device is formed on the plug portion. If, furthermore, the second engagement device is formed on the base portion, then the first engagement device and the second engagement device are formed on different portions of the second closure part, and are thus spatially and functionally separated from one another.
[0020] For example, the first engagement device can be formed by an engagement opening on the plug portion. The engagement opening can for example be formed as a depression on an end-face surface of the plug portion, which faces along the third spatial direction towards the associated adjustment element. The first engagement portion of the at least one adjustment element is in engagement with the engagement opening in the closed position of the closure device, such that thereby preferably a movement of the second closure part relative to the first closure part along the first spatial direction and furthermore also along the second spatial direction is blocked.
[0021] The first locking portion and the second locking portion on the at least one locking element are preferably spatially separated from one another and thus formed at different locations on the at least one locking portion. Furthermore, preferably the first engagement device and the second engagement device are also spatially separated from one another, on the second closure part. The at least one locking element engages, in the closed position, with different portions in associated, functionally and spatially separated engagement devices on the second closure part, and thus locks the closure parts relative to one another, in the closed position.
[0022] The at least one locking element is arranged adjustably on the body of the first closure part. In this case, the at least one locking element can for example be movable in a rotationally or linearly displaceable manner, relative to the body of the first closure part.
[0023] In one non-limiting embodiment, the at least one locking element is mounted so as to be pivotable relative to the body of the closure part, about a bearing axis. The bearing axis of the locking element, about which the locking element is pivotable relative to the body of the first closure part, can for example face along the second spatial direction. An adjustment movement of the locking element thus takes place rotatably in a pivot plane which is spanned by the first spatial direction and the third spatial direction that is perpendicular to the first spatial direction and to the second spatial direction.
[0024] In one non-limiting embodiment, the first engagement portion protrudes radially to the bearing axis, along a first direction. In contrast, the second engagement portion protrudes radially to the bearing axis, along a second direction.
[0025] For example, the first engagement portion and the second engagement portion protrude in substantially opposite directions relative to the bearing axis, with respect to the bearing axis. The first engagement portion and the second engagement portion thus protrude from the bearing axis diametrically along different directions, such that the engagement portions are formed on different ends of the at least one locking element.
[0026] In one non-limiting embodiment, the first closure part of the closure device comprises a first magnet device. The second closure part in contrast comprises a second magnet device. The magnet devices interact in a magnetically attracting manner, such that for closing the closure device the closure parts are pulled towards one another, and in particular the locking portion is pulled into engagement with the receiving opening formed on the body of the first closure part. A simple, comfortable closing process results, which is assisted magnetically by the magnetic attractive force of the magnet devices.
[0027] The first magnet device can be arranged on the body of the first closure part or also on the at least one locking element. The second magnet device can for example be arranged on the plug portion.
[0028] In one non-limiting embodiment, the at least one locking element comprises a third magnet device which interacts with the second magnet device in a magnetically attracting manner in the closed position, such that at least one locking element is loaded in the direction of the locking position by the magnetic attraction. The third magnet device can implement the first magnet device or can be provided as an additional magnet device in addition to the first magnet device, on the first closure part. Thus, a magnetic preload acts on the at least one locking element in the direction of the locking position, which preload is caused by a third magnet device being arranged on the locking element which interacts in a magnetically attracting manner with the second magnet device of the second closure part. If the plug portion of the second closure part is inserted into the receiving opening of the first closure part, in order to close the closure device, then the at least one locking element is loaded by magnetic interaction of the third magnet device on the at least one locking element and the second magnet device on the second closure part such that the at least one locking element is brought into engagement, with the engagement portions formed thereon, with the associated engagement devices, and is held in the locking position.
[0029] In addition or alternatively, a spring-mechanical preload in the direction of the locking position can act on the at least one locking element, such that when the closure device is closed the at least one locking element automatically assumes the closed position and thus locks the closure parts relative to one another when the closure parts are fixed against one another in the closed position.
[0030] In one non-limiting embodiment, the at least one locking element can be adjusted out of the locking position into a release position, relative to the body, for overcoming the locking effect. In the release position, the at least one locking element is adjusted, compared to the locking position, on the body of the first closure part such that the engagement of the first locking portion with the associated, first engagement device, and furthermore also the engagement of the second locking portion with the associated second engagement device is overcome and thus the closure parts are no longer locked relative to one another. The closure parts can thus be separated from one another for opening the closure device.
[0031] In one non-limiting embodiment, the first closure part comprises a preload element, for example in the form of a mechanical spring, which preloads the at least one locking element relative to the body in the direction of the release position. If the closure device is opened, then the at least one locking element is held on the body of the first closure part, owing to the spring preload, in the release position. If the closure device is closed and if for this purpose the closure parts are fixed on one another such that the plug portion of the second closure part engages into the receiving opening on the body of the first closure part, then the at least one locking element is for example magnetically loaded by magnetic interaction of a third magnet device on the at least one locking element and the second magnet device on the second closure part and thereby adjusted relative to the body of the first closure part such that the at least one locking element is transferred into the locking position and thus an engagement is established between the first locking portion and the associated first engagement device and between the second locking portion and the associated second engagement device.
[0032] In one non-limiting embodiment, the at least one locking element is held magnetically in the release position, relative to the body, when the closure device is open. Instead of or in addition to a preload element in the form of a mechanical spring, which preloads the locking element mechanically in the direction of the release position, a magnetic preload can thus also be provided, for example in that a third magnet device of the at least one locking element interacts with a fourth magnet device on the body of the first closure part, and thus the locking element is loaded mechanically in the direction of the release position when the closure device is open. If the closure device is closed, the magnetic attraction between the third magnet device on the locking element and the second magnet device on the second closure part is superimposed on and exceeds the magnetic preload in the direction of the release position, such that the at least one locking element is transferred from the release position into the locking position when the closure device is closed.
[0033] A fourth magnet device is not necessarily configured as a separate magnet device on the first closure part. For example, the fourth magnet device can also be formed by the first magnet device of the first closure part.
[0034] For example, the at least one locking element is held magnetically in the release position relative to the body, when the closure device is open, in that there is an interaction of the third magnet device of the locking element and the first magnet device on the body of the first closure part. If a plurality of locking elements is provided, then additionally or alternatively an interaction between the third magnet devices of the plurality of locking elements can exist, which loads the locking elements in the direction of the release position when the closure device is open. In this case, there can be both an interaction between the third magnet devices of the locking elements, and furthermore an interaction of the third magnet devices with the first magnet device, wherein the interactions hold the locking elements, together, in the release position.
[0035] In one non-limiting embodiment, the at least one locking element comprises an actuation portion for actuation by a user for transfer from the locking position into the release position. The actuation portion is accessible from outside the first closure part, and can be actuated by a user in order to adjust the at least one locking element on the body of the first closure part. For example, the actuation portion of the at least one locking element engages through an opening on the body of the first closure part, and can thus be actuated from the outside by a user.
[0036] An actuation direction along which the actuation portion is to be actuated in order to transfer the at least one locking element out of the locking position into the release position can for example be oriented along the third spatial direction that is perpendicular to the first spatial direction and to the second spatial direction.
[0037] If two locking elements are provided on the first closure part, the locking elements can for example be intended to be actuated towards one another along opposing actuation directions facing along the third spatial direction, for example, in order to transfer the locking elements out of the locking position into the release position. For this purpose, a user can for example act on the locking elements with two fingers and press the elements towards one another, such that as a result the locking elements are transferred together out of the locking position into the release position.
[0038] In one non-limiting embodiment, the second closure part comprises an actuation element which can be actuated for transferring the at least one locking element into the release position on the second closure part. An actuation of the locking element for adjustment out of the locking position into the release position thus takes place indirectly by an actuation of an actuation element on the second closure part, which, upon actuation, acts on the at least one locking element on the first closure part.
[0039] If two locking elements are adjustably arranged on the first closure part, then the second closure part can for example comprise two actuation elements, wherein each locking element on the first closure part is assigned one actuation element on the second closure part.
[0040] In one non-limiting embodiment, the actuation element is configured to act mechanically on the at least one locking element on the first closure part, for the purpose of adjustment. The actuation element can for example be movable along the third spatial direction, on the second closure part. If the actuation element on the second closure part is adjusted, then the actuation element acts mechanically on the at least one locking element and adjusts the at least one locking element from the locking position into the release position, in order to be able to open the closure device.
[0041] In another non-limiting embodiment, the actuation element is configured to adjust a magnet device, for example the second magnet device, on the second closure part in order to transfer the at least one locking element into the release position by magnetic interaction of the at least one locking element with the magnet device. In a first position of the actuation element, the magnet device assumes a position on the second closure part in which the magnet device interacts in a magnetically attracting manner with the third magnet device of the at least one locking element. By adjusting the actuation element, the position of the magnet device on the second closure part can be changed, such that the magnet device is adjusted relative to the third magnet device of the at least one locking element and a magnetic attractive force preferably reverses into a magnetic repelling force. On account of the changed magnetic interaction, the at least one locking element is transferred from the locking position into the release position and the closure device is thus unlocked.
[0042] In this non-limiting embodiment, the magnet device, for example the second magnet device, can for example be arranged on the actuation element. The actuation element can for example be rotatably arranged on the second closure part, for example on the plug portion of the second closure part, such that rotating the actuation element makes it possible for the magnet device on the second closure part to rotated and thus for its position to be changed.
[0043] In this non-limiting embodiment, an axis of rotation of the actuation element can for example be oriented along the third spatial direction which extends perpendicularly to the first spatial direction and to the second spatial direction.
[0044] In other possible non-limiting embodiments, however, the axis of rotation can also be oriented along the first or second spatial axis.
[0045] In one non-limiting embodiment, the plug portion of the second closure part comprises a resiliently deflectable deflection arm. The first engagement device is formed on the deflection arm. In this case, it can be provided that the deflection arm is deflectable on the second closure part in order to bring the first locking portion out of engagement with the first engagement device. The deflection arm on the second closure part can for example be resilient along the third spatial direction, e.g., transversely to the first spatial direction and to the second spatial direction. The deflection arm is thus resiliently adjustable on the second closure part, along the third spatial direction.
[0046] In general it is possible that the closure device can be unlocked by adjusting the at least one locking element out of the locking position into a release position, in order to thus unlock, and thus open, the closure device by actuating the at least one locking element. In addition or alternatively, however, it can also be possible that the engagement of at least one engagement portion with an associated engagement device is overcome in that a portion of the second closure part, on which the engagement device is arranged, is adjusted. This can take place by the resilient adjustment of the deflection arm on the plug portion of the second closure part. The locking engagement between the engagement device of the deflection arm and the associated engagement portion of the at least one locking element is thus overcome not by an adjustment movement of the locking element, but rather by a deflection movement on the resilient deflection arm. If the engagement has been overcome by deflection of the deflection arm, then a movement of the closure parts relative to one another at least along one spatial direction is released, such that the closure device can be opened.
[0047] In one non-limiting embodiment, the second closure part comprises a blocking element which is configured for locking the deflection arm on the second closure part, in a blocking position, such that the deflection arm cannot be brought out of engagement with the first engagement device. The blocking element is adjustable out of the blocking position, such that the deflection arm can be brought out of engagement with the first engagement device. In the closed position of the closure device, the blocking element assumes the blocking position, such that a resilient deflection of the deflection arm is not possible. The blocking element can be adjusted on the second closure part, in order to overcome the blocking of the deflection arm. If the blocking is overcome, then the deflection arm can be resiliently deflected and thus the engagement of the engagement device on the deflection arm with the associated locking portion on the at least one locking element can be overcome.
[0048] In particular, in one non-limiting embodiment in which a blocking element is provided for blocking the deflection arm in the closed position, the deflection arm can be resiliently formed on the second closure part in such a way that the deflection arm is deflected automatically on the second closure part when the closure parts are loaded relative to one another along one spatial direction when the blocking element is adjusted out of the blocking position. If the deflection arm is thus not blocked against deflection, on the second closure part, then the deflection arm can be automatically resiliently adjusted on the second closure part when there is a loading between the closure parts. In the closed position, the deflection arm is blocked by the blocking element, such that a resilient deflection of the deflection arm is not possible. For opening the closure device, the blocking element can be adjusted out of the blocking position, such that a resilient adjustment of the deflection arm is released and, upon loading of the closure parts relative to one another, the deflection arm is automatically deflected and the engagement between the engagement device on the deflection arm and the associated engagement portion on the at least one locking element is thus automatically overcome.
[0049] If the first closure part comprises two locking elements, then preferably two resiliently deflectable deflection arms are formed on the second closure part, which arms each carry an engagement device which is in each case associated with a locking portion of the associated locking element.
[0050] The first magnet device and the second magnet device can for example each be formed by a permanent magnet. In the closed position, the magnet devices face one another with opposite poles and thus attract one another magnetically, such that on the one hand the closing of the closure device is magnetically assisted by the magnet devices, and on the other hand the closure parts are also magnetically loaded relative to one another in the closed position.
[0051] In another non-limiting embodiment, the first magnet device and the second magnet device can be formed by a permanent magnet on the one hand and by a passively magnetic armature, for example made of a ferromagnetic material, for example an iron material, on the other hand.
[0052] A third magnet device of the at least one locking element can for example be formed by a permanent magnet or, if the second magnet device of the second closure part is formed by a permanent magnet, by a passively magnetic armature.
[0053] A fourth magnet device on the body of the first closure part for interacting with a third magnet device of the at least one locking element can be formed by a permanent magnet or, if the third magnet device is formed by a permanent magnet, by a passively magnetic armature. The fourth magnet device can also be implemented by the first magnet device of the first closure part.BRIEF DESCRIPTION OF THE DRAWINGS

[0098] FIGS. 1 to 6 show a first non-limiting embodiment of a closure device 1 which comprises a first closure part 2 and a second closure part 3. The closure parts 2, 3 can be fixed on one another and are interconnected, in a closed position shown in FIG. 3A, in such a way that the closure parts 2, 3 are fixed in a manner fixed in position along all the spatial directions X, Y, Z and furthermore in a non-rotatable manner relative to one another.
[0099] The closure device 1 can be opened such that the closure parts 2, 3 can be separated from one another, as is shown in FIG. 5A.
[0100] The first closure part 2 comprises a body 20 on which a U-shaped receiving opening 203 is formed.
[0101] The second closure part 3 comprises a base portion 30 which extends transversely along a spatial direction Y and from which a plug portion 31 protrudes along a spatial direction X. The second closure part 3 can be inserted by the plug portion 31 into the receiving opening 203 on the body 20 of the first closure part 2, in order to in this way close the closure device 1.
[0102] A first magnet device 22 is arranged on the body 20. In contrast, a second magnet device 32 is arranged on the second closure part 3. The magnet devices 22, 32 interact in a magnetically attracting manner, such that the closure parts 2, 3 are pulled towards one another for closing the closure device 1 when the closure parts 2, 3 move closer together, and thus the plug portion 31 is brought into engagement with the receiving opening 203 on the body 20 of the closure part 2 in a magnetically assisted manner.
[0103] Two locking elements 21A, 21B are pivotably arranged on the body 20 of the first closure part 2. The locking elements 21A, 21B are mounted on associated bearing elements 201A, 201B, in the form of bearing pins, on a housing part 200 of the body 20, which each define a bearing axis, and are pivotable about the bearing elements relative to the body 20.
[0104] Each locking element 21A, 21B comprises a first locking portion 210 and a second locking portion 211. The locking portions 210, 211 of each locking element 21A, 21B protrude relative to the associated bearing element 201A, 201B along different directions and thus face approximately diametrically away from one another with respect to the associated bearing element 201A, 201B. The locking portions 210, 211 are thus functionally and spatially separated from one another, in that the locking portions 210, 211 are spaced apart from one another in a pivot plane of the respective locking element 21A, 21B that is spanned by the spatial directions X, Y.
[0105] An actuation portion 212 is formed on each locking element 21A, 21B, which actuation portion lies in an associated opening 202A, 202B on the body 20 of the closure part 2 and is accessible from the outside, such that the locking elements 21A, 21B can be actuated by hand by a user.
[0106] Third magnet devices 213 are arranged on the locking elements 21A, 21B, which magnet devices are in particular configured for interacting with the second magnet device 32 of the second closure part 3, in the closed position.
[0107] In the closed position of the closure device 1, shown in FIGS. 3A to 3D, the locking portions 210, 211 of each locking element 21A, 21B engage in an associated engagement device 310A, 310B, 311A, 311B, in each case, on the closure part 3, as is visible from the sectional view according to FIG. 3D. First engagement devices 310A, 310B, which are associated with the first locking portions 210 of the locking elements 21A, 21B, are formed on the plug portion 31 in the form of engagement openings. Second engagement devices 311A, 311B are formed, in contrast, on the base portion 30 of the closure part 3, in the form of engagement openings that are open downwards (with respect to the spatial direction X).
[0108] In the closed position according to FIGS. 3A to 3D, the closure parts 2, 3 are fixed on one another and interconnected, such that the closure parts 2, 3 are held in a manner fixed in location and non-rotatably relative to one another. In this case, the magnet devices 22, 32 interact in a magnetically attracting manner. Furthermore, the magnet devices 213 of the locking elements 21A, 21B interact in a magnetically attracting manner with the magnet device 32 of the closure part 3, such that the locking elements 21A, 21B are loaded in the direction of a locking position shown in FIG. 3D, in which position the locking portions 210, 211 are in engagement with the associated engagement devices 310A, 310B, 311A, 311B on the closure part 3.
[0109] The engagement of the first locking portions 210 of the locking elements 21A, 21B with the associated engagement devices 310A, 310B in the form of the engagement openings on the plug portion 31 is such that the closure part 3 is locked relative to the closure part 2, along the spatial direction X and furthermore also along the spatial direction Z that is perpendicular to the spatial directions X, Y. In the case of locking elements 21A, 21B located in the locking position, the plug portion 31 cannot be brought out of engagement with the receiving opening 203 along the spatial direction X and furthermore likewise along the spatial direction Z, because this is counteracted by the engagement of the engagement portions 210 into the engagement devices 310A, 310B in the form of the engagement openings on the plug portion 31.
[0110] The engagement of the second engagement portions 211 into the associated engagement devices 311A, 311B on the base portion 30 of the closure part 3 furthermore locks a movement of the closure part 3 along the spatial direction Z relative to the closure part 2, but not a movement of the closure parts 2, 3 relative to one another along the spatial direction X. The additional engagement of the second engagement portions 211 of the locking elements 21A, 21B with the associated engagement devices 311A, 311B on the base portion 30 of the closure part 3 in particular causes locking also of a rotational adjustment of the closure parts 2, 3 about the spatial direction Y, in addition to a linear adjustment of the closure parts 2, 3 relative to one another along the spatial directions X, Z.
[0111] For opening the closure device 1, the locking elements 21A, 21B on the closure part 2 can be actuated by a user by hand, in that a user for example presses inwards along an actuation direction B with two fingers on the actuation portions 212 of the locking elements 21A, 21B, such that the locking elements 21A, 21B are adjusted on the closure part 2, as can be seen from FIG. 4. As a result, the engagement of the engagement portions 210 with the engagement devices 310A, 310B on the plug portion 31 of the closure part 3, and furthermore also the engagement of the engagement portions 211 with the engagement devices 311A, 311B on the base portion 30, is overcome, such that the locking elements 21A, 21B are unlocked. The closure direction 1 can thus be opened.
[0112] In this case, the closure parts 2, 3 can be separated from one another in a variable manner after unlocking the locking elements 21A, 21B.
[0113] Thus, the closure parts 2, 3 can be pulled apart from one another along the spatial direction X, as is shown in FIGS. 5A, 5B.
[0114] Furthermore, the closure parts 2, 3 can also be separated from one another along the spatial direction Z, as is shown in FIG. 6.
[0115] An oblique movement having movement vector components along the spatial direction X and along the spatial direction Z is also conceivable.
[0116] A movement of the closure parts 2, 3 rotationally, relative to one another, about the spatial direction Y is furthermore conceivable.
[0117] When the closure device 1 is open, as can be seen for example from FIG. 5B, the locking elements 21A, 21B are preferably held in their unlocked release position.
[0118] If the closure device 1 is intended to be closed again, then the closure parts 2, 3 can be fixed against one another such that the plug portion 31 is introduced into the receiving opening 203. In this case, the closure parts 2, 3 can be interconnected linearly along the spatial direction X or along the spatial direction Z or along an oblique movement having movement components along the spatial direction X and the spatial direction Z, or also rotationally with a rotational movement about the spatial direction Y, analogously to the movability of the closure parts 2, 3 relative to one another for opening the closure device 1.
[0119] The locking elements 21A, 21B are for example held by magnetic interaction of the magnet devices 213 with the magnet device 22 of the closure part 2 in the unlocked release position according to FIG. 5B, when the closure device 1 is open. In another non-limiting embodiment, shown in FIG. 7, additional magnet devices 23, for example in the form of passively magnetic armatures, can be provided on the closure part 2, which devices interact with the magnet devices 213, for example formed by permanent magnets, on the locking elements 21A, 21B, and load the locking elements 21A, 21B in the direction of the release position.
[0120] When the closure device 1 is open, the locking elements 21A, 21B are thus held in the release position by magnetic interaction between the magnet devices 213, 23.
[0121] If the closure device 1 is closed, and if the plug portion 31 of the closure part 3 is in engagement with the associated receiving opening 203 on the body 20 of the closure part 2, as is shown in FIG. 7, then the magnetic attraction between the magnet devices 213 on the locking elements 21A, 21B and the magnet device 32 on the closure part 3 is superimposed on and exceeds the magnetic attraction between the magnet devices 213 and the magnet devices 23, such that the locking elements 21A, 21B are moved in the direction of the locking position and are located in the locking position in the closed position of the closure device 1, in which locking position the engagement portions 210, 211 of the locking elements 21A, 21B are in engagement with the associated engagement devices 310A, 310B, 311A, 311B of the closure part 3.
[0122] In yet another non-limiting embodiment, shown in FIG. 8, the locking elements 21A, 21B are spring preloaded in the direction of the release position, relative to the body 20 of the closure part 2, by mechanical spring elements 24. If the closure device 1 is open, then the locking elements 21A, 21B are moved by the spring elements 24 on the body 20 of the closure part 2 into the release position, and held there. If the closure device 1 is closed, then the magnetic attractive force between the magnet devices 213 on the locking elements 21A, 21B and the magnet device 32 on the closure part 3 is superimposed on the spring-mechanical preload and exceeds this, such that the locking elements 21A, 21B are moved into the locking position according to FIG. 8 on account of the magnetic interaction with the magnet device 32 on the closure part 3.
[0123] In the case of a non-limiting embodiment shown in FIGS. 9A-9C to 11, locking elements 21A, 21B do not comprise any actuation portions that are accessible from the outside and can be actuated by a user, as in the case of the non-limiting embodiments set out above. Instead, actuation elements 33A, 33B are arranged on the closure part 3, which elements can be moved along an actuation direction B, on the closure part 3, facing along the spatial direction Y, and act on the locking elements 21A, 21B for adjusting the locking elements 21A, 21B.
[0124] In view of the locking function of the locking elements 21A, 21B in the closed position, shown in FIGS. 9A-9C, the locking elements 21A, 21B are functionally identical to the locking elements 21A, 21B of the non-limiting embodiments described above, and therefore reference is made to the explanations in this respect. In particular, in the closed position, as can be seen from FIG. 9C, locking portions 210 of the locking elements 21A, 21B are in engagement with associated engagement devices 310A 310B, 311A, 311B on the closure part 3, such that the closure parts 2, 3 are locked relative to one another.
[0125] If a user acts on the actuation elements 33A, 33B along the actuation direction B and presses the elements towards one another, the locking elements 21A, 21B can be adjusted out of the locking position according to FIG. 9C and be transferred into the release position according to FIG. 10. The locking effect of the locking elements 21A, 21B is thus overcome, and therefore the closure parts 2, 3 can be separated from one another, as is shown in FIG. 11. In turn, as is explained on the basis of the non-limiting embodiment according to FIGS. 1-6, the closure parts 2, 3 can be moved relative to one another along the spatial direction X, along the spatial direction Z perpendicular to the spatial directions X, Y, or also by a rotational movement about the spatial direction Y, in order to separate the closure parts 2, 3 from one another.
[0126] In the case of a non-limiting embodiment shown in FIGS. 12A-12C to 14, the locking elements 21A, 21B are configured functionally as in the non-limiting embodiment according to FIGS. 9A-9C to 11. In particular, the locking elements 21A, 21B do not comprise any actuation portions that are actuatable by a user and accessible from the outside. In the locking position shown in FIG. 12C, the locking elements 21A, 21B engage with the locking portions 210, 211 in associated engagement devices 310A, 310B, 311A, 311B on the closure part 3 and thus lock the closure parts 2, 3 relative to one another in the closed position.
[0127] In the non-limiting embodiment shown in FIGS. 12A-12C to 14, the plug portion 31 of the closure part 3 comprises resiliently deflectable deflection arms 313A, 313B, on which the engagement devices 310A, 310B in the form of engagement openings are formed. The deflection arms 313A, 313B are in particular resiliently deflectable in an adjustment plane spanned by the spatial directions X, Y, by a user acting on the deflection arms 313A, 313B via handle portions 314A, 314B formed on the deflection arms 313A, 313B and pushing the arms towards one another, as can be seen from FIGS. 13A and 13B.
[0128] In the closed position of the closure device 1, corresponding to the position according to FIG. 12C, the deflection arms 313A, 313B assume a relaxed position, in which the deflection arms 313A, 313B are not deflected and the engagement portions 210 of the locking elements 21A, 21B are in engagement with the engagement devices 310A, 310B on the deflection arms 313A, 313B.
[0129] By deflecting the deflection arms 313A, 313B, as shown in FIGS. 13A, 13B, the engagement of the engagement devices 310A, 310B on the deflection arms 313A, 313B with the respectively associated locking portion 210 of the locking elements 21A, 21B can be overcome, such that the closure parts 2, 3 can be removed from one another along the spatial direction X, as is visible from FIG. 14. By deflection of the deflection arms 313A, 313B, the locking effect is thus overcome along the spatial direction X, but not along the spatial direction Z, because the engagement portions 211 of the locking elements 21A, 21B remain in engagement with the engagement devices 311A, 311B, as can be seen from FIG. 13B.
[0130] If the closure parts 2, 3 have been moved relative to one another, for the purpose of opening, by a comparatively small adjustment path along the spatial direction X, then the engagement of the engagement portions 211 with the associated engagement devices 311A, 311B is overcome, such that the closure parts 2, 3 can be freely separated from one another.
[0131] Otherwise, the non-limiting embodiment according to FIGS. 12A-12C to 14 is functionally comparable in particular to the non-limiting embodiments illustrated above on the basis of FIGS. 1-6, and therefore reference is made to the explanations in this respect.
[0132] In the case of a non-limiting embodiment shown in FIGS. 15A to 15E, the locking elements 21A, 21B are functionally identical to the locking elements 21A, 21B of the non-limiting embodiments according to FIGS. 9A-9C to 11 and 12A-12C to 14.
[0133] In the non-limiting embodiment shown in FIGS. 15A to 15E, the plug portion 31 is formed rigidly on the base portion 30 of the closure part 3. On the plug portion 31, an actuation element 34 is rotatable about an axis of rotation 340 facing along the spatial direction Y and carries the magnet device 32 of the closure part 3, such that the position of the magnet device 32, formed by a permanent magnet, on the plug portion 31 can be changed.
[0134] In the closed position, the magnet device 32, as shown in FIG. 15C, interacts in a magnetically attracting manner with the magnet devices 213 on the locking elements 21A, 21B, such that the locking elements 21A, 21B are loaded in the direction of the locking position and the engagement portions 210, 211 of the locking elements 21A, 21B are in engagement with the engagement devices 310A, 310B, 311A, 311B on the closure part 3. In this case, the magnetic attraction is brought about in that the magnet devices 213 oppose magnetic poles N, S of the magnet device 32 with opposite magnetic poles S, N, as can be seen from the sectional view according to FIG. 15C.
[0135] If the actuation element 34 is rotated on the plug portion 31 about the axis of rotation 340 along a direction of rotation D about 180°, as is visible from FIGS. 15D and 15E, then the position of the magnetic poles S, N of the magnet device 32 is reversed, as can be seen from FIG. 15E. Now, the magnet devices 213 of the locking elements 21A, 21B on the one hand and the magnet device 32 on the other hand oppose one another with the same poles S, N, such that the magnet devices 213, 32 interact in a magnetically repelling manner.
[0136] The locking elements 21A, 21B are thus transferred magnetically into the release position according to FIG. 15E, and the closure device 1 is unlocked, such that the closure parts 2, 3 can be separated from one another.
[0137] A non-limiting embodiment shown in FIGS. 16A-16C corresponds to the non-limiting embodiment according to FIGS. 1-6.
[0138] In contrast to the non-limiting embodiment according to FIGS. 1-6, magnet devices 213 are arranged on the locking elements 21A, 21B, on a side of the bearing element 201A, 201B facing the engagement portions 211. For loading the locking elements 21A, 21B in the locking position according to FIG. 16C, the magnet devices 213 interact in a magnetically repelling manner with the magnet device 32 of the closure part 3.
[0139] Furthermore, the non-limiting embodiment according to FIGS. 16A-16C is functionally identical to the non-limiting embodiment according to FIGS. 1-6.
[0140] A non-limiting embodiment shown in FIGS. 17A-17C corresponds to the non-limiting embodiment according to FIGS. 1-6.
[0141] In contrast to the non-limiting embodiment according to FIGS. 1-6, the engagement portions 211 of the locking elements 21A, 21B are configured as hooks, which, by engagement with the engagement devices 311A, 311B on the closure part 3, also provide a locking effect along the spatial direction X, such that the two engagement portions 210, 211 of the locking elements 21A, 21B lock both along the spatial direction X and along the spatial direction Z, by the engagement with the associated engagement devices 310A, 310B, 311A, 311B.
[0142] Otherwise, the non-limiting embodiment is functionally identical to the non-limiting embodiment according to FIGS. 1-6, and therefore reference is also made to the explanations in this respect.
[0143] A non-limiting embodiment shown in FIGS. 18A-18C to 21 corresponds to the non-limiting embodiment according to FIGS. 12A-12C to 14. In particular, resiliently deflectable deflection arms 313A, 313B are formed on the plug portion 31, which arms bear the engagement devices 310A, 310B in the form of the engagement openings.
[0144] In the non-limiting embodiment shown, a blocking element 35 is provided on the closure part 3, which element is adjustable along the spatial direction X relative to the closure part 3. The blocking element 35 comprises a blocking portion 350 which is displaceable in an opening 315 formed between the deflection arms 313A, 313B.
[0145] In a blocking position, shown in FIG. 18C, the blocking portion 350 lies between the deflection arms 313A, 313B and in this way blocks a resilient deflection movement of the deflection arms 313A, 313B. In the closed position of the closure device 1 according to FIG. 18C, the deflection arms 313A, 313B are thus blocked, such that the engagement between the locking elements 21A, 21B with the associated engagement devices 310A, 310B, 311A, 311B locks the closure parts 2, 3 relative to one another.
[0146] For opening the closure device 1, the blocking element 35 can be moved in an unlocking direction C into a position on the closure part 3 in which the blocking portion 350 no longer blocks the deflection arms 313A, 313B, as can be seen from FIG. 19.
[0147] In the non-limiting embodiment shown, the deflection arms 313A, 313B are formed so as to be so flexible that, in the case of loading of the closure parts 2, 3 relative to one another along the spatial direction X, the deflection arms 313A, 313B automatically swerve resiliently inwards, as is shown in FIG. 20. The closure parts 2, 3 can thus be separated from one another, as can be seen from FIG. 21.
[0148] If the closure parts 2, 3 have been moved relative to one another by a small adjustment path along the spatial direction X, and as a result the engagement of the engagement portions 211 of the locking elements 21A, 21B with the associated engagement devices 311A, 311B has also been overcome, then the closure parts 2, 3 can be separated from one another in free movement.
[0149] When the closure device 1 is open, the locking elements 21A, 21B are for example held by magnetic interaction of the magnet devices 213 with the magnet device 22 of the closure part 2 in the release position. Additionally or alternatively, a spring preload can act on the locking elements 21A, 21B in the direction of the release position.
[0150] In yet a further non-limiting embodiment, shown in FIGS. 22A-22C, in contrast to the non-limiting embodiment according to FIGS. 1-6 the locking elements 21A, 21B do not comprise any magnet devices 213, but rather are preloaded relative to one another in a spring-mechanical manner by a preload element 25 in the form of an elastically deformable spring element that is formed in one piece with the locking elements 21A, 21B.
[0151] If the locking elements 21A, 21B are moved out of the locking position according to FIG. 22C by manual actuation along the actuation direction B on the actuation portions 212, this takes place counter to the spring preload of the preload element 25. If the closure device 1 is closed, the locking elements 21A, 21B come into engagement with the associated engagement devices 310A, 310B, 311A, 311B automatically, on account of the spring preload of the preload element 25, such that the locking effect of the locking elements 21A, 21B in the closed position according to FIG. 22C is established automatically upon closing of the closure device 1.
[0152] Otherwise, the non-limiting embodiment according to FIGS. 22A-22C is functionally identical to the non-limiting embodiment according to FIGS. 1-6, and therefore reference is also made to the explanations in this respect.
[0153] The concept on which the solution is based is not limited to the embodiments set out above, but rather can be also be implemented in other manners.
[0154] The closure device can serve for interconnecting any modules.
[0155] For example, the closure device can be used as a closure for a wristband, for example on a wristwatch or a piece of jewelry.
[0156] In another non-limiting embodiment, the closure device can provide a belt strap closure for interconnecting two belts.
[0157] Other possible uses of the closure device are conceivable and possible.
