Description

Field of the Invention

[0001] The present invention relates to a latching device for connecting two components to each other according to the preamble of claim 1.

[0002] Such a latching device includes a first latching member having a body portion, a receiving opening formed at the body portion, and at least one locking element that can be adjusted relative to the body portion. The latching device further includes a second latching member having an insertion section. To close the latching device, the insertion section can be inserted into the receiving opening. In the closed position, the insertion section engages in the receiving opening, and the second latching member is locked relative to the first latching member by at least one locking element, such that the first latching member and the second latching member are held on each other. To separate the first latching member and the second latching member from each other, the locking action of at least one locking element can be released, and the first latching member and the second latching member can be separated from each other by removing the insertion section from the receiving opening. Background Art

[0003] In the latching device known from WO 2022 / 152418 A1, a latching element of one latching member can pivot relative to a base element of that latching member in order to act on an engaging element of another latching member in the closed position, thereby connecting the latching members to each other. Summary of the Invention

[0004] The object of the present invention is to provide a latching device that enables a comfortable placement of the latching members on each other while the latching members are reliably held on each other in the closed position.

[0005] The object is achieved by the subject matter having the features of claim 1.

[0006] Accordingly, at least one locking element has a first locking section and a second locking section. The second latching member has a first engaging means and a second engaging means. In the closed position, the locking element is in a locked position relative to the body portion of the first latching member, in which the first locking section engages with the first engaging means and the second locking section engages with the second engaging means. To release the locking action of at least one locking element, the first locking section can be disengaged from the first engaging means and / or the second locking section can be disengaged from the second engaging means.

[0007] At least one locking element, which is adjustably arranged at the body of the first fastening element, serves to lock the second fastening element relative to the first fastening element in the closed position. To this end, the locking element has a first locking section and a second locking section, which are spatially and functionally separated from each other, and when the fastening device is in the closed position, the first locking section and the second locking section engage in associated engagement means at the second fastening element. Since the first locking section engages in a first engagement means and the second locking section engages in a second engagement means, the second fastening element is locked at the first fastening element such that the insertion section remains engaged with the receiving opening and the fastening elements cannot be separated from each other, at least not without releasing the locking action.

[0008] The locking action can be released to open the fastening device in such a way that the first locking section can be disengaged from the first engagement means and / or the second locking section can be disengaged from the second engagement means. Thus, to release the locking action, at least one engagement between the first locking section and the first engagement means or between the second locking section and the second engagement means must be released. If at least one locking pair, i.e., the engagement between the first locking section and the first engagement means or between the second locking section and the second engagement means, has been released, the second fastening element can be moved relative to the first fastening element at least along one spatial direction such that the insertion section can be disengaged from the receiving opening along the spatial direction, so that the fastening elements can be disengaged from each other.

[0009] The first fastening element can have one or more, for example two, locking elements, which are adjustably arranged at the body of the first fastening element. Each locking element can have two locking sections here, which engage in the associated engagement means of the second fastening element in the closed position. In the case of a plurality of locking elements being provided, only one locking element can also have two locking sections.

[0010] Compared with existing solutions, the fastening device of the described type offers the following advantages: There can be a mountability and separability along different spatial directions, and the mounting is magnetically supported here. The fastening device of the type described here can be used to connect straps, belts, and harnesses to protective equipment or as a fastening on bags, textiles, clothing, shoes, or also as a fastening on watches, electronic devices, jewelry, etc.

[0011] In a design, the plug-in section can be inserted into the receiving opening along a first spatial direction and along a second spatial direction perpendicular to the first spatial direction. Thus, the plug-in section can not only be inserted into the receiving opening along a single spatial direction, but also along the first spatial direction and along the second spatial direction perpendicular to the first spatial direction, or along a movement inclined relative to the first and second spatial directions, which is composed of vector components of movement along the first and second spatial directions. In addition, it is also possible to place the plug-in section in the receiving opening by a rotational movement, for example, a rotational movement about a third spatial direction perpendicular to the first and second spatial directions. Thus, the plug-in section can be variably inserted into the receiving opening by completely different movements, such that the locking elements can be variably connected to each other by different movements.

[0012] In a design, in the closed position, by engaging the first locking section with the first engaging device and the second locking section with the second engaging device, the plug-in section is locked in the receiving opening not only along the first spatial direction but also along the second spatial direction. Thus, the locking action of at least one locking element causes the locking elements to be spatially fixed relative to each other in the closed position, and thus orientationally and positionally fixed, and in particular torsionally held on each other. Due to the engagement of the locking section of at least one locking element of the first locking element with the engaging device, the relative movement of the locking elements along the first spatial direction and along the second spatial direction is locked, and the relative movement along an inclined direction composed of vector components of movement along the first and second spatial directions is also locked, as well as the rotational movement.

[0013] In a design, the engagement of the first engaging section with the first engaging device locks the relative movement of the first and second locking elements relative to each other not only along the first spatial direction but also along the second spatial direction. Thus, the engagement of the first engaging section with the first engaging device exerts a locking action not only along the first spatial direction and along the second spatial direction but also in an inclined direction composed of vector components of movement along the first and second spatial directions in a vectorial manner. For example, the engagement of the first engaging section with the first engaging device does not lock or only insufficiently locks the rotational relative movement of the first and second locking elements, for example, about a third spatial direction perpendicular to the first and second spatial directions.

[0014] In a design, the engagement of the second engagement section with the second engagement device locks the relative movement of the first locking element and the second locking element relative to each other along the second spatial direction, but not along the first spatial direction. Thus, in the closed position of the locking device, the locking effect of the engagement of the second engagement section with the second engagement device 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 section of at least one locking element and the second engagement device is used to lock the rotational movement of the locking elements relative to each other about the third spatial direction, such that when the locking device is in the closed position, through the combined locking effect of the engagement of the first engagement section with the first engagement device and the engagement of the second engagement section with the second engagement device, the locking elements are fixed in orientation, in particular also torsionally fixed relative to each other.

[0015] In a design, an adjustment plane is defined by the first spatial direction and a third spatial direction perpendicular to the first and second spatial directions. For example, to release the locking effect of at least one locking element, the first locking section can be disengaged from the first engagement device in the adjustment plane and / or the second locking section can be disengaged from the second engagement device in the adjustment plane. Thus, the locking engagement can be released by the relative movement between the respective engagement sections of at least one locking element and the associated engagement device of the second locking element, such that the locking effect of at least one locking pair is released, thereby releasing the relative movement of the locking elements relative to each other along at least one spatial direction, such as along the first spatial direction, along the second spatial direction, along an inclined direction or along a rotational direction, by loosening the locking effect.

[0016] In a design, the second locking element has a base section that projects transversely to the first spatial direction relative to the insertion section. Thus, the base section extends transversely to the first spatial direction, in particular along the third spatial direction. The insertion section extends from the base section along the first spatial direction such that the insertion section can be inserted into the receiving opening at the body of the first locking element to close the locking device, but here, the base section is outside the receiving opening at the body of the first locking element.

[0017] In a design, the second engagement device is formed at the base section and the second locking section of at least one locking element engages with the second engagement device in the closed position of the locking device. The second engagement device can, for example, be formed as an engagement opening with which the second locking section of at least one locking element engages in the closed position. The engagement can be achieved such that the relative movement of the second locking section relative to the second engagement device along the second spatial direction is in particular locked.

[0018] In a design, the first engaging device is formed at the plugging section. Furthermore, if the second engaging device is formed at the base section, the first engaging device and the second engaging device are formed at different sections of the second locking element, so as to be spatially and functionally separated from each other.

[0019] For example, the first engaging device can be formed by an engaging opening at the plugging section. The engaging opening can be formed, for example, at the end side of the plugging section as a recess pointing in the third spatial direction towards the associated adjusting element. In the closed position of the locking device, the first engaging section of at least one adjusting element engages with the engaging opening, such that preferably, the movement of the second locking element relative to the first locking element along the first spatial direction and also along the second spatial direction is locked.

[0020] The first locking section and the second locking section at at least one locking element are preferably spatially separated from each other, so as to be at different positions on at least one locking section. Furthermore, the first engaging device and the second engaging device at the second locking element are preferably also spatially separated from each other. At least one locking element engages with the associated, functionally and spatially separated engaging devices at the second locking element in different sections in the closed position, so as to lock the locking elements relative to each other in the closed position.

[0021] At least one locking element is adjustably arranged at the body of the first locking element. At least one locking element can, for example, move relative to the body of the first locking element in a rotatable or linearly movable manner.

[0022] In a design, at least one locking element is pivotally supported relative to the body of the locking element about a support axis. The support axis of the locking element can, for example, point along the second spatial direction, and the locking element can pivot about the support axis relative to the body of the first locking element. Therefore, the adjusting movement of the locking element is carried out rotationally in a pivot plane extending through the first spatial direction and a third spatial direction perpendicular to the first spatial direction and the second spatial direction.

[0023] In a design, the first engaging section projects radially relative to the support axis along the first direction. In contrast, the second engaging section projects radially relative to the support axis along the second direction.

[0024] For example, the first engaging section and the second engaging section project relative to the support axis in substantially opposite directions with respect to the support axis. Therefore, the first engaging section and the second engaging section project in exactly opposite directions along different directions from the support axis, such that the engaging sections are formed at different ends of at least one locking element.

[0025] In one embodiment, the first locking element has a first magnetic device. In contrast, the second locking element has a second magnetic device. The magnetic devices interact in a magnetically attractive manner, so that in order to close the locking device, the locking elements are attracted toward each other and in particular the locking section engages with the receiving opening formed on the body of the first locking element. This results in a simpler, more comfortable closing process that is magnetically supported by the magnetic attraction of the magnetic devices.

[0026] The first magnetic device can be arranged on the body of the first closure part, or can also be arranged on at least one locking element. The second magnetic device can be arranged on the plug section, for example.

[0027] In one design, at least one locking element has a third magnetic device, which acts in a magnetically attracted manner with the second magnetic device in the closed position, so that at least one locking element is loaded toward the locked position by magnetic attraction. The third magnetic device can realize the first magnetic device, or can be set as an additional magnetic device in addition to the first magnetic device at the first locking member. Therefore, the magnetic preload towards the locked position caused by the following method acts on at least one locking element: a third magnetic device is provided at the locking element, which acts in a magnetically attracted manner with the second magnetic device of the second locking member. If the plug-in section of the second locking member is inserted into the receiving opening of the first locking member in order to close the locking device, at least one locking element is loaded by the magnetic interaction of the third magnetic device at the at least one locking element and the second magnetic device of the second locking member, so that at least one locking element is engaged with the associated engagement device with the engagement section formed thereon and is held in the locked position.

[0028] Additionally or alternatively, a spring-mechanical preload toward the locking position can act on at least one locking element so that when the locking device is closed, at least one locking element is automatically in the closed position, thereby locking the locking parts relative to each other when the locking parts are placed on each other in the closed position.

[0029] In the initial position, the at least one locking element can be adjusted relative to the body from a locking position into a release position in order to release the locking effect. Compared to the locking position, in the release position, the at least one locking element is adjusted at the body of the first locking element in such a way that the engagement of the first locking section with the associated first engagement means and also the engagement of the second locking section with the associated second engagement means is released, so that the locking elements are no longer locked relative to each other. As a result, the locking elements can be separated from each other in order to open the locking device.

[0030] In a design, the first locking element has a preloading element, such as a preloading element in the form of a mechanical spring, which preloads at least one locking element towards the release position relative to the body. If the latching device is opened, at least one locking element is held at the body of the first locking element due to the spring preloading in the release position. If the latching device is closed and the locking elements are arranged on one another such that the insertion section of the second locking element engages in the receiving opening at the body of the first locking element, at least one locking element is magnetically loaded, for example, by the magnetic interaction of a third magnetic device at at least one locking element and a second magnetic device at the second locking element, such that it is adjusted relative to the body of the first locking element such that at least one locking element is transferred into the locking position, thereby establishing an engagement between the first locking section and the associated first engaging device and between the second locking section and the associated second engaging device.

[0031] In a design, in the case of an open latching device, at least one locking element is magnetically held in the release position relative to the body. Thus, instead of or in addition to a preloading element in the form of a mechanical spring that magnetically preloads the locking element towards the release position, magnetic preloading can also be provided, for example, by the interaction of a third magnetic device of at least one locking element and a fourth magnetic device at the body of the first locking element, such that in the case of an open latching device, the locking element is magnetically loaded towards the release position. If the latching device is closed, the magnetic attraction between the third magnetic device at the locking element and the second magnetic device at the second locking element overrides and exceeds the magnetic preloading towards the release position, such that when the latching device is closed, at least one locking element is transferred from the release position into the locking position.

[0032] The fourth magnetic device does not necessarily have to be configured as a separate magnetic device at the first locking element. For example, the fourth magnetic device can also be constituted by the first magnetic device of the first locking element.

[0033] For example, in the case of an open latching device, at least one locking element is magnetically held in the release position relative to the body in such a way that there is an interaction between the third magnetic device of the locking element and the first magnetic device at the body of the first locking element. If there are multiple locking elements, an interaction can additionally or alternatively exist between the third magnetic devices of the multiple locking elements, which load the locking elements towards the release position when the latching device is open. Here, not only can there be an interaction between the third magnetic devices of the locking elements with one another, but there can also be an interaction between the third magnetic device and the first magnetic device, wherein the interaction holds the locking elements jointly in the release position.

[0034] In a design, at least one locking element has a manipulation section for being manipulated by a user to transfer from a locked position to a released position. The manipulation section can be accessed from outside the first locking member and can be manipulated by the user to adjust at least one locking element at the body of the first locking part. For example, the manipulation section of at least one locking element extends through an opening at the body of the first locking part, so that it can be manipulated by the user from the outside.

[0035] For example, the manipulation direction can be oriented along a third spatial direction perpendicular to the first spatial direction and the second spatial direction, and the manipulation section should be manipulated along the manipulation direction to transfer at least one locking element from the locked position to the released position.

[0036] If two locking elements are provided at the first locking part, these two locking elements can, for example, be manipulated towards each other in opposite manipulation directions pointing along the third spatial direction to transfer the locking elements from the locked position to the released position. For this purpose, the user can, for example, act on the locking elements with two fingers and press them towards each other, so that the locking elements are jointly transferred from the locked position to the released position thereby.

[0037] In a design, the second locking part has a manipulation element which can be manipulated at the second locking part to transfer at least one locking element to the released position. Thus, the manipulation of the locking element to adjust from the locked position to the released position is carried out indirectly by manipulating the manipulation element at the second locking part. When manipulated, the manipulation element acts on at least one locking element at the first locking part.

[0038] If two locking elements are adjustably provided at the first locking part, the second locking part can, for example, have two manipulation elements, wherein the manipulation elements at the second locking part are associated with each locking element at the first locking part.

[0039] In a design, the manipulation element is configured to mechanically act on at least one locking element at the first locking part for adjustment. The manipulation element can, for example, move along the third spatial direction at the second locking part. If the manipulation element is adjusted at the second locking part, the manipulation element mechanically acts on at least one locking element and adjusts at least one locking element from the locked position to the released position so as to be able to open the locking device.

[0040] In another design, the actuating element is configured to adjust a magnetic device, for example a second magnetic device, at the second locking element in order to transfer at least one locking element into a release position by means of a magnetic interaction between at least one locking element and the magnetic device. In a first position of the actuating element, the magnetic device is in an orientation at the second locking device in which the magnetic device interacts with a third magnetic device of at least one locking element in a magnetically attracting manner. By adjusting the actuating element, the orientation of the magnetic device at the second locking element can be changed such that the magnetic device is adjusted relative to the third magnetic device of at least one locking element and the magnetic attraction force is preferably reversed to a magnetic repulsion force. Due to the changed magnetic interaction, at least one locking element is transferred from the locking position into the release position, thereby unlocking the locking device.

[0041] In this design, the magnetic device, for example the second magnetic device, can be arranged at the actuating element, for example. The actuating element can be rotatably arranged, for example, at a plug-in section of the second locking element, for example, such that the magnetic device at the second locking element can be rotated by twisting the actuating element, thereby changing its orientation.

[0042] In this design, the axis of rotation of the actuating element can be oriented, for example, along a third spatial direction perpendicular to the first and second spatial directions.

[0043] However, in other possible designs, the axis of rotation can also be oriented along the first or second spatial axis.

[0044] In one design, the plug-in section of the second locking element has an elastically deflectable deflection arm. A first engaging device is formed at the deflection arm. It can be provided here that the deflection arm is deflectable at the second locking element in order to disengage the first locking section from the first engaging device. The elasticity of the deflection arm at the second locking element can exist, for example, along the third spatial direction, i.e., transversely to the first and second spatial directions. Thus, the deflection arm can be elastically adjusted at the second locking element along the third spatial direction.

[0045] Generally, it is feasible to unlock a latching device by adjusting at least one locking element from a locked position to a released position, so as to unlock and thus open the latching device by manipulating at least one locking element. However, additionally or alternatively, it may also be feasible to disengage at least one engaging section from an associated engaging device by adjusting a section of a second latching member provided with an engaging device. This can be done by elastically adjusting a deflection arm at an insertion section of the second latching member. Thus, the locking engagement between the engaging device of the deflection arm and the associated engaging section of at least one locking element is not released by the adjusting movement of the locking element, but by the deflection movement at the elastic deflection arm. If the engagement has been released by the deflection of the deflection arm, the movement of the latching members relative to each other along at least one spatial direction is released, such that the latching device can be opened.

[0046] In one design, the second latching member has a blocking element configured to lock the deflection arm at the second latching member in a blocking position such that the deflection arm cannot disengage from the first engaging device. The blocking element can be adjusted out of the blocking position such that the deflection arm can disengage from the first engaging device. In the closed position of the latching device, the blocking element is in the blocking position such that elastic deflection of the deflection arm is not feasible. The blocking element can be adjusted at the second latching member to relieve the blocking of the deflection arm. If the blocking is relieved, the deflection arm can be elastically deflected, so that the engagement between the engaging device at the deflection arm and the associated locking section at at least one locking element can be disengaged.

[0047] Particularly in a design with a blocking element for blocking the deflection arm in the closed position, the deflection arm can be elastically formed at the second latching member such that when the latching members are loaded relative to each other along a spatial direction with the blocking element adjusted out of the blocking position, the deflection arm automatically deflects at the second latching member. Thus, if the deflection arm is not blocked at the second latching member to prevent deflection, the deflection arm can be automatically elastically adjusted at the second latching member when loading is applied between the latching members. In the closed position, the deflection arm is blocked by the blocking element such that elastic deflection of the deflection arm is not feasible. To open the latching device, the blocking element can be adjusted out of the blocking position such that the elastic adjustment of the deflection arm is released, and when the latching members are loaded relative to each other, the deflection arm automatically deflects, thereby automatically disengaging the engagement between the engaging device at the deflection arm and the associated engaging section at at least one locking element.

[0048] If the first latching member has two locking elements, preferably two elastically deflectable deflection arms are formed at the second latching member, and the deflection arms respectively carry engaging devices which are respectively associated with the locking sections of the associated locking elements.

[0049] The first magnetic device and the second magnetic device can for example be formed by permanent magnets respectively. In the closed position, the magnetic devices point their different poles towards each other, so as to attract magnetically, such that on the one hand, the closing of the latching device is magnetically supported by the magnetic devices, and on the other hand, the latch members are also magnetically loaded relative to each other in the closed position.

[0050] In another design, the first magnetic device and the second magnetic device can on the one hand be formed by permanent magnets and on the other hand can be formed by a passively magnetic armature, which is for example made of a ferromagnetic material, such as iron material.

[0051] The third magnetic device of at least one locking element can for example be designed by a permanent magnet, or if the second magnetic device of the second latch member is formed by a permanent magnet, the third magnetic device can be designed by a passively magnetic armature.

[0052] The fourth magnetic device, which is located at the body of the first latch member and is used to cooperate with the third magnetic device of at least one locking element, can be formed by a permanent magnet, or if the third magnetic device is formed by a permanent magnet, the fourth magnetic device can be formed by a passively magnetic armature. The fourth magnetic device can also be realized by the first magnetic device of the first latch member. Description of the Drawings

[0097] Figures 1 to 6 A first embodiment of a latch device 1 is shown, which has a first latch member 2 and a second latch member 3. The latch members 2, 3 can be placed on one another and are connected to one another in the Figure 3A closed position shown, such that the latch members 2, 3 are fixed in orientation along all spatial directions X, Y, Z and are furthermore torsionally fixed against rotation relative to one another.

[0098] The latch device 1 can be opened such that the latch members 2, 3 can be separated from one another, as shown in Figure 5A ;

[0099] The first latch member 2 has a body 20, at which a receiving opening 203 having a U-shaped configuration is formed.

[0100] The second latch member 3 has a base section 30, which extends transversely along the spatial direction Y, and a plug section 31, which projects from the base section along the spatial direction X. The second latch member 3 can be inserted with the plug section 31 into the receiving opening 203 at the body 20 of the first latch member 2 in order to close the latch device 1 in that way.

[0101] A first magnetic device 22 is provided at the body 20. In contrast thereto, a second magnetic device 32 is provided at the second latch member 3. The magnetic devices 22, 32 act together in a magnetically attracting manner such that, in order to close the latch device 1, when the latch members 2, 3 approach one another, the latch members 2, 3 attract one another, so that the plug section 31 engages with the receiving opening 203 at the body 20 of the latch member 2 in a magnetically supported manner.

[0102] At the body 20 of the first fastener 2, two locking elements 21A, 21B are pivotally provided. The locking elements 21A, 21B are supported at the housing part 200 of the body 20 at associated support elements 201A, 201B in the form of support spindles, each defining a support axis, and can pivot relative to the body 20 thereon.

[0103] Each of the locking elements 21A, 21B has a first locking section 210 and a second locking section 211. The locking sections 210, 211 of each of the locking elements 21A, 21B project in different directions relative to the associated support elements 201A, 201B and point approximately oppositely away from each other with respect to the associated support elements 201A, 201B. Thus, the locking sections 210, 211 are functionally and spatially separated from each other in such a way that the locking sections 210, 211 are spaced apart from each other in the pivot planes of the respective locking elements 21A, 21B extending in the spatial directions X, Y.

[0104] At each of the locking elements 21A, 21B, an actuating section 212 is formed, which is placed in associated openings 202A, 202B at the body 20 of the fastener 2 and can be accessed from the outside, so that the locking elements 21A, 21B can be manually actuated by the user.

[0105] At the locking elements 21A, 21B, a third magnetic device 213 is provided, which is designed in particular for cooperation with the second magnetic device 32 of the second fastener 3 in the closed position.

[0106] In Figures 3A to 3D it is shown that in the closed position of the fastening device 1, the locking sections 210, 211 of each of the locking elements 21A, 21B engage into respective associated engaging devices 310A, 310B, 311A, 311B at the fastener 3, as can be seen from a sectional view according to Figure 3D The first engaging devices 310A, 310B associated with the first locking section 210 of the locking elements 21A, 21B are formed in the form of engaging openings at the plug-in section 31. In contrast thereto, the second engaging devices 311A, 311B are formed in the form of engaging openings (open downwardly with respect to the spatial direction X) at the base section 30 of the fastener 3.

[0107] In accordance with Figures 3A to 3DIn the closed position, the locking elements 2, 3 are placed on one another and connected to one another such that the orientations of the locking elements 2, 3 are fixed and torsionally resistant relative to one another. The magnetic devices 22, 32 act together in a magnetically attractive manner here. In addition, the magnetic devices 213 of the locking elements 21A, 21B act together in a magnetically attractive manner with the magnetic device 32 of the locking element 3 such that the locking elements 21A, 21B are loaded towards the locking position shown in Figure 3D in which the locking sections 210, 211 engage with the associated engagement devices 310A, 310B, 311A, 311B at the locking element 3.

[0108] The first locking section 210 of the locking elements 21A, 21B engages with the associated engagement devices 310A, 310B in the form of engagement openings at the insertion section 31 such that the locking element 3 is locked relative to the locking element 2 along the spatial direction X and also along a spatial direction Z perpendicular to the spatial directions X, Y. When the locking elements 21A, 21B are in the locking position, the insertion section 31 cannot be disengaged from the receiving opening 203 along the spatial direction X and also cannot be disengaged along the spatial direction Z because the engagement section 210 engages into the engagement devices 310A, 310B in the form of engagement openings at the insertion section 31 against this disengagement.

[0109] In addition, the second engagement section 211 engages into the associated engagement devices 311A, 311B at the base section 30 of the locking element 3 to lock the movement of the locking element 3 relative to the locking element 2 along the spatial direction Z, but does not lock the movement of the locking elements 2, 3 relative to one another along the spatial direction X. The additional engagement of the second engagement section 211 of the locking elements 21A, 21B with the associated engagement devices 311A, 311B at the base section 30 of the locking element 3 particularly causes that in addition to the linear adjustment of the locking elements 2, 3 relative to one another along the spatial directions X, Z, the rotational adjustment of the locking elements 2, 3 about the spatial direction Y is also locked.

[0110] To open the locking device 1, the locking elements 21A, 21B at the locking element 2 can be manually manipulated by the user in such a way that the user, for example, presses inwards along the manipulation direction B with two fingers at the manipulation section 212 of the locking elements 21A, 21B such that the locking elements 21A, 21B at the locking element 2 are adjusted as can be seen from Figure 4 This disengages the engagement of the engagement section 210 with the engagement devices 310A, 310B at the insertion section 31 of the locking element 3 and also disengages the engagement of the engagement section 211 with the engagement devices 311A, 311B at the base section 30 such that the locking elements 21A, 21B are unlocked. Thus, the locking device 1 can be opened.

[0111] After unlocking the locking elements 21A, 21B, the locking elements 2, 3 can then be separated from each other in a variable manner.

[0112] Therefore, the locking elements 2, 3 can be pulled apart from each other in the spatial direction X, as is shown in Figure 5A , Figure 5B .

[0113] In addition, the locking elements 2, 3 can also be separated from each other in the spatial direction Z, as is shown in Figure 6 .

[0114] An inclined movement with movement vector components in the spatial direction X and in the spatial direction Z is also conceivable.

[0115] A movement of the locking elements 2, 3 rotating relative to each other about the spatial direction Y is also conceivable.

[0116] In the case of the open locking device 1, for example, it can be seen from Figure 5B that the locking elements 21A, 21B are preferably held in their unlocked release positions.

[0117] If the locking device 1 is to be closed again, the locking elements 2, 3 can be placed on each other such that the plug-in section 31 is introduced into the receiving opening 203. The locking elements 2, 3 can be connected to each other linearly or also rotationally with a rotational movement about the spatial direction Y along the spatial direction X or along the spatial direction Z or along an inclined movement having movement components in the spatial direction X and the spatial direction Z, analogous to the movability of the locking elements 2, 3 relative to each other for opening the locking device 1.

[0118] When the locking device 1 is open, the locking elements 21A, 21B are held in the unlocked release position according to Figure 5B by the magnetic interaction between the magnetic means 213 of the locking elements 21A, 21B and the magnetic means 22 of the locking element 2. In Figure 7 a further design shown, an additional magnetic means 23, for example in the form of a passive magnetic armature, can be provided at the locking element 2, which additional magnetic means acts together with the magnetic means 213, for example formed by a permanent magnet, at the locking elements 21A, 21B and loads the locking elements 21A, 21B towards the release position.

[0119] Therefore, in the case of the open locking device 1, the locking elements 21A, 21B are held in the release position by the magnetic interaction between the magnetic means 213, 23.

[0120] If the locking device 1 is closed and the plug-in section 31 of the locking element 3 is in engagement with the associated receiving opening 203 at the body 20 of the locking element 2, as is shown in Figure 7As shown, the magnetic attraction between the magnetic devices 213 at the locking elements 21A, 21B and the magnetic device 32 at the locking member 3 covers and exceeds the magnetic attraction between the magnetic device 213 and the magnetic device 23, such that the locking elements 21A, 21B move towards the locking position and are in this locking position in the closed position of the locking device 1, in which the engaging sections 210, 211 of the locking elements 21A, 21B engage with the associated engaging devices 310A, 310B, 311A, 311B of the locking member 3.

[0121] In Figure 8 In a further alternative embodiment shown, the locking elements 21A, 21B are spring-preloaded towards the release position via a mechanical spring element 24 relative to the body 20 of the locking member 2. If the locking device 1 is opened, the locking elements 21A, 21B are moved into the release position by the spring element 24 at the body 20 of the locking member 2 and remain there. If the locking device 1 is closed, the magnetic attraction between the magnetic devices 213 at the locking elements 21A, 21B and the magnetic device 32 at the locking member 3 covers the mechanical spring preloading and exceeds the mechanical spring preloading, such that the locking elements 21A, 21B move into the locking position according to Figure 8 due to the magnetic interaction with the magnetic device 32 at the locking member 3.

[0122] In Figures 9A - 9C to Figure 11 In the embodiment shown, the locking elements 21A, 21B do not have an externally accessible and user-manipulable actuating section as in the embodiments described above. Instead, actuating elements 33A, 33B are provided at the locking member 3, which can be actuated at the locking member 3 in an actuating direction B pointing in the spatial direction Y and act on the locking elements 21A, 21B to adjust the locking elements 21A, 21B.

[0123] Regarding the locking function of the locking elements 21A, 21B in the closed position shown in Figures 9A - 9C , the locking elements 21A, 21B are functionally identical to the locking elements 21A, 21B of the embodiments described above, such that reference should be made to the description thereof. In particular, as can be seen from Figure 9C , in the closed position, the locking sections 210 of the locking elements 21A, 21B engage with the associated engaging devices 310A, 310B, 311A, 311B at the locking member 3, such that the locking members 2, 3 are locked relative to one another.

[0124] By the user acting on the actuating elements 33A, 33B in the actuating direction B and pressing them towards one another, the locking elements 21A, 21B can be adjusted away from the according toFigure 9C to the locking position and transferred into the release position according to Figure 10 . Thus, the locking action of the locking elements 21A, 21B is released, such that the locking fasteners 2, 3 can be separated from each other, as shown in Figure 11 . As described according to the embodiment of Figures 1 - 6 , the locking fasteners 2, 3 can in turn move relative to each other 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 locking fasteners 2, 3 from each other.

[0125] In Figures 12A - 12C to Figure 14 in the embodiment shown, the locking elements 21A, 21B are functionally designed as in the embodiment according to Figures 9A - 9C to Figure 11 . In particular, the locking elements 21A, 21B do not have a manipulable, externally accessible manipulation section. In the locking position shown in Figure 12C , the locking elements 21A, 21B engage with the associated engagement devices 310A, 310B, 311A, 311B at the locking fastener 3 with locking sections 210, 211, thereby locking the locking fasteners 2, 3 relative to each other in the closed position.

[0126] In Figures 12A - 12C to Figure 14 in the embodiment shown, the plug-in section 31 of the locking fastener 3 has elastically deflectable deflection arms 313A, 313B at which engagement devices 310A, 310B are formed in the form of engagement openings. The deflection arms 313A, 313B can in particular be elastically deflected in an adjustment plane extending through the spatial directions X, Y in such a way that the user acts on the deflection arms 313A, 313B via gripping sections 314A, 314B formed at the deflection arms 313A, 313B and presses the deflection arms towards each other, as can be seen from Figure 13A and Figure 13B .

[0127] In the closed position of the locking device 1, corresponding to the position according to Figure 12C , the deflection arms 313A, 313B are in the relaxed position, in which the deflection arms 313A, 313B are not deflected and the engagement sections 210 of the locking elements 21A, 21B engage with the engagement devices 310A, 310B at the deflection arms 313A, 313B.

[0128] By deflection of the deflection arms 313A, 313B, as in Figure 13A , Figure 13BAs shown, it is possible to release the engagement of the locking sections 210 respectively associated with the engaging devices 310A, 310B at the deflection arms 313A, 313B and the locking elements 21A, 21B, such that the locking elements 2, 3 can be pulled apart from each other along the spatial direction X, as can be seen from Figure 14 This can be seen. Thus, by the deflection of the deflection arms 313A, 313B, the locking action is released along the spatial direction X, but not along the spatial direction Z, because the engaging sections 211 of the locking elements 21A, 21B remain engaged with the engaging devices 311A, 311B, as can be seen from Figure 13B This can be seen.

[0129] If the locking elements 2, 3 are moved relative to each other along the spatial direction X by a relatively small adjustment distance for opening, the engagement of the engaging section 211 with the associated engaging devices 311A, 311B is also released, such that the locking elements 2, 3 can be freely separated from each other.

[0130] In other respects, the embodiments according to Figures 12A - 12C to Figure 14 are functionally particularly similar to the embodiments described above according to Figures 1 - 6 , such that reference should also be made to the explanations therefor.

[0131] In the embodiment shown in Figures 15A to 15E , the locking elements 21A, 21B are functionally the same as the locking elements 21A, 21B of the embodiments according to Figures 9A - 9C to Figure 11 and Figures 12A - 12C to Figure 14 .

[0132] In the embodiment shown in Figures 15A to 15E , the plug section 31 is rigidly formed at the base section 30 of the locking element 3. At the plug section 31, the actuating element 34 can be twisted about a rotational axis 340 pointing along the spatial direction Y and carries the magnetic device 32 of the locking element 3, such that the orientation of the magnetic device 32 formed by the permanent magnet at the plug section 31 can be changed.

[0133] In the closed position, the magnetic device 32, as shown in Figure 15C , acts in a magnetically attracting manner together with the magnetic devices 213 at the locking elements 21A, 21B, such that the locking elements 21A, 21B are loaded towards the locking position, and the engaging sections 210, 211 of the locking elements 21A, 21B engage with the engaging devices 310A, 310B, 311A, 311B at the locking element 3. This magnetic attraction is caused by the fact that the magnetic devices 213 are arranged with opposite magnetic poles S, N relative to the magnetic poles N, S of the magnetic device 32, as can be seen from the sectional view according to Figure 15C .

[0134] If the actuating element 34 is rotated 180° about the axis of rotation 340 in the rotational direction D at the insertion section 31, as can be seen from Figure 15D and Figure 15E then the orientation of the magnetic poles S, N of the magnetic means 32 is reversed, as can be seen from Figure 15E . Now, on the one hand, the magnetic means 213 of the locking elements 21A, 21B and, on the other hand, the magnetic means 32 are arranged with like poles S, N opposite each other, such that the magnetic means 213, 32 act together in a magnetically repulsive manner.

[0135] Accordingly, the locking elements 21A, 21B are magnetically displaced into the release position according to Figure 15E , and the latching device 1 is unlocked such that the latch members 2, 3 can be separated from each other.

[0136] In Figures 16A - 16C the embodiment shown is identical to the embodiment according to Figures 1 - 6 .

[0137] Differently from the embodiment according to Figures 1 - 6 , the magnetic means 213 at the locking elements 21A, 21B are arranged on the side of the support elements 201A, 201B facing the engagement section 211. In order to load the locking elements 21A, 21B into the locking position according to Figure 16C , the magnetic means 213 act together in a magnetically repulsive manner with the magnetic means 32 of the latch member 3.

[0138] Furthermore, the embodiment according to Figures 16A - 16C is functionally identical to the embodiment according to Figures 1 - 6 .

[0139] In Figures 17A - 17C the embodiment shown is identical to the embodiment according to Figures 1 - 6 .

[0140] Differently from the embodiment according to Figures 1 - 6 , the engagement sections 211 of the locking elements 21A, 21B are configured as hooks which also provide a locking action along the spatial direction X by engaging with the engagement means 311A, 311B at the latch member 3, such that the two engagement sections 210, 211 of the locking elements 21A, 21B are locked not only along the spatial direction X but also along the spatial direction Z by engaging with the associated engagement means 310A, 310B, 311A, 311B.

[0141] In other respects, the embodiment is functionally identical to the embodiment according to Figures 1 - 6 , such that reference should also be made to the description thereof.

[0142] InFigures 18A - 18C to Figure 21 The embodiments shown in Figures 12A - 12C to Figure 14 are the same as the embodiments according to

[0143] In the embodiment shown, a blocking element 35 is provided at the latch 3, which can be adjusted relative to the latch 3 along the spatial direction X. The blocking element 35 has a blocking section 350, which can move in an opening 315 formed between the deflection arms 313A, 313B.

[0144] In Figure 18C the shown blocking position, the blocking section 350 is placed between the deflection arms 313A, 313B and in this way blocks the elastic deflection movement of the deflection arms 313A, 313B. Thus, in the closed position of the latching device 1 according to Figure 18C the deflection arms 313A, 313B are blocked such that the engagement between the locking elements 21A, 21B and the associated engagement means 310A, 310B, 311A, 311B locks the latches 2, 3 relative to each other.

[0145] To open the latching device 1, the blocking element 35 can be moved along the unlocking direction C to a position at the latch 3 in which the blocking section 350 no longer blocks the deflection arms 313A, 313B, as can be seen from Figure 19 this.

[0146] In the embodiment shown, the deflection arms 313A, 313B are elastically formed such that when the latches 2, 3 are loaded relative to each other along the spatial direction X, the deflection arms 313A, 313B automatically elastically deflect inwards, as shown in Figure 20 this. Thus, the latches 2, 3 can be separated from each other, as can be seen from Figure 21 this.

[0147] If the latches 2, 3 are moved relative to each other along the spatial direction X by a small adjustment distance such that the engagement between the engagement sections 211 of the locking elements 21A, 21B and the associated engagement means 311A, 311B is also released, the latches 2, 3 can be separated from each other in free movement.

[0148] In the case of the open latching device 1, the locking elements 21A, 21B are held in the released position, for example, by the magnetic interaction of the magnetic means 213 at the locking elements 21A, 21B with the magnetic means 22 of the latch 2. Additionally or alternatively, the spring preloading at the locking elements 21A, 21B can act towards the released position.

[0149] In Figures 22A - 22C yet another alternative embodiment shown, different from the embodiment according to Figures 1 - 6 the locking elements 21A, 21B do not have a magnetic means 213, but are preloaded relative to each other in a spring-mechanical manner via a preloading element 25 in the form of an elastically deformable spring element integrally formed with the locking elements 21A, 21B.

[0150] If the locking elements 21A, 21B are moved away from the locking position according to FIG. 22 by manual manipulation along the manipulation direction B at the manipulation section 212, this occurs against the spring preloading of the preloading element 25. If the latching device 1 is closed, due to the spring preloading of the preloading element 25, the locking elements 21A, 21B automatically engage with the associated engaging means 310A, 310B, 311A, 311B, such that when the latching device 1 is closed, the locking action of the locking elements 21A, 21B in the locking position according to Figure 22C automatically occurs.

[0151] In other respects, the embodiment according to Figures 22A - 22C is functionally the same as the embodiment according to Figures 1 - 6 such that reference should also be made to the description thereof.

[0152] The concept on which the present invention is based is not limited to the embodiments described above, but can also be implemented in other ways.

[0153] The latching device can be used to connect any components to each other.

[0154] For example, the latching device can be used as a latch for a wristband, for example, on a watch or jewelry.

[0155] In another design, the latching device can provide a buckle for connecting two straps to each other.

[0156] Other uses of the latching device are conceivable and feasible.
