[0001] Locking device with a mounting element

[0002] Description

[0003] The invention relates to a closure device according to the preamble of claim 1.

[0004] Such a closure device comprises a first closure part which has a housing part, a spring locking element, and a first magnetic device. The spring locking element and the first magnetic device are arranged on the housing part in an assembled position of the first closure part. A second closure part has a locking piece and a second magnetic device. In the assembled position, the first closure part and the second closure part can be placed against one another along a closing direction to close the closure device and are held against one another in a closed position by engagement of the locking piece with the spring locking element along the closing direction. To open the closure device, the closure parts can be released from one another by a relative movement along an opening direction that differs from the closing direction.

[0005] WO 2008 / 006357 A2 discloses various designs of closure devices in which a spring locking element in the form of an elastically resilient part is arranged on a closure part, which can be brought into engagement with a locking piece on another closure part in order to close the closure device. Magnetic devices are arranged on the closure parts, for example in the form of permanent magnets or in the form of one or more permanent magnets and a passively magnetic, ferromagnetic armature, which interact in a magnetically attractive manner to close the closure device, so that when the closure parts are placed against one another, the closure parts are drawn towards one another and the locking piece on one closure part engages the spring locking element on the other closure part.By means of a relative movement, for example by a linear, lateral sliding movement or by a rotary movement, an engagement between the locking piece and the spring locking element can be removed so that the locking parts can be separated from one another.

[0006] Other designs of closure devices with magnetically interacting closure parts are known, for example, from WO 2009 / 092368 A2.

[0007] A closure device of the type in question consists of a comparatively large number of components. The first closure part comprises a housing part, a spring locking element, and a first magnetic device, which are to be joined together to assemble the first closure part. In this case, there is always a need for simple, cost-effective production, possibly with the possibility of automation, for joining the components of the individual closure parts together.

[0008] The object of the present invention is to provide a locking device which is easy to assemble, with little weakening of a housing of the first locking part carrying the spring locking element.

[0009] This object is achieved by an article having the features of claim 1.

[0010] Accordingly, the first closure part has a mounting element which, for mounting the first closure part, can be inserted into a mounting opening of the housing part together with the first magnetic device and / or the spring locking element in a mounting direction different from the closing direction and is immovably connected to the housing part in the mounted position of the first closure part.

[0011] In a normal operating state, the closure parts are each in an assembled position. In the assembled position of the first closure part, the first magnetic device and the spring locking element are connected to the housing part of the first closure part. Furthermore, in a mounted position of the second closure part, the second magnetic device is arranged on a housing part of the second closure part that supports the locking piece. In such a normal operating state, the closure parts can be placed against one another along the closing direction to close the closure device.

[0012] In the closed position, the closure parts are held together by the engagement of the locking piece of the second closure part with the spring locking element of the first closure part along the closing direction and are thus fixed relative to one another. By a relative movement between the closure parts, for example by a movement of the first or second closure part as a whole or by a movement of a section of the first or second closure part relative to the other closure part, the locking piece and the spring locking element can be disengaged from one another, wherein this relative movement occurs along an opening direction different from the closing direction.

[0013] By disengaging the locking piece and the spring locking element, the locking parts can be separated from each other and are separated from each other in an open position of the locking device.

[0014] In this case, the opening direction differs from the closing direction, meaning that the opening direction points in a different direction than the closing direction. The opening direction is therefore neither aligned nor opposite to the closing direction. The opening direction can, for example, be perpendicular to the closing direction or at an oblique angle to the closing direction.

[0015] An opening movement can, for example, correspond to a linear movement. Accordingly, the opening direction extends in a straight line. In another embodiment, however, the opening movement can also correspond to a rotary movement. In this case, the opening movement points around an associated rotational axis.

[0016] To facilitate the assembly of the first closure part, a mounting element is provided which can be inserted into a mounting opening in the housing part of the first closure part for mounting the first closure part. The mounting element can serve as a carrier for the first magnetic device and / or the spring locking element such that the first magnetic device and / or the spring locking element can be placed on the housing part of the first closure part via the mounting element. For assembly, the mounting element is inserted in the assembly direction into the mounting opening of the housing part such that, in the assembled position of the first closure part, the first magnetic device and / or the spring locking element are mounted on the housing part via the mounting element and thus assume a proper functional position in or on the housing part.

[0017] In this case, the mounting direction being different from the closing direction means that the mounting direction points in a different direction than the closing direction. The mounting direction is therefore neither aligned nor opposed to the closing direction. The mounting direction can, for example, be perpendicular to the closing direction or at an angle to the closing direction.

[0018] The mounting direction can be linear. However, the mounting direction can also be along a curved path of movement along which the mounting element is to be inserted into the mounting opening of the housing part.

[0019] The mounting direction can be the same as the opening direction. However, the mounting direction can also point in a different direction than the opening direction.

[0020] For example, the mounting direction and the opening direction may each be perpendicular to the closing direction, wherein the mounting direction and the opening direction may be in the same direction or point along different directions (in a plane perpendicular to the closing direction).

[0021] Because the mounting element serves as a support for the first magnetic device and / or the spring locking element, assembly can be simplified and, if necessary, automated. Thus, the first magnetic device and / or the spring locking element can be arranged on the housing part via the mounting element by inserting the mounting element into the mounting opening of the housing part in the assembly direction. The housing part can, for example, be designed in one piece and can thus preferably be designed to be stable and resilient.By means of the mounting element, the first magnetic device and / or the spring locking element can be placed in the housing part in such a way that in the mounted position of the first closure part, the first magnetic device and the spring locking element assume their intended position for interaction with the other closure part, in particular the second magnetic device of the second closure part and the locking piece of the second closure part.

[0022] In one embodiment, the mounting element serves as a support for both the first magnetic device and the spring locking element. The mounting element thus allows the first magnetic device and the spring locking element to be mounted to the housing part in a single assembly step.

[0023] In one embodiment, the mounting direction is linear. In this embodiment, the mounting element can be inserted as a drawer element into the mounting opening of the housing part of the first closure part in order to mount the first closure part.

[0024] In one embodiment, the first magnetic device and / or the spring locking element are arranged on the mounting element in a pre-assembly position. The mounting element can be inserted into the mounting opening of the housing part of the first closure part in the assembly direction, thereby transferring the first closure part into the assembled position. For example, in the pre-assembly position, the first magnetic device and the spring locking element are arranged on the mounting element, so that the mounting element, together with the first magnetic device and the spring locking element, can be inserted into the mounting opening of the housing part in order to assemble the first closure part.

[0025] The first magnetic device of the first closure part and the second magnetic device of the second closure part can each be configured, for example, with one or more permanent magnets. In another configuration, one of the magnetic devices is configured with one or more permanent magnets, while the other magnetic device is configured with one or more passively magnetic elements in the form of ferromagnetic armatures. To close the closure device, the magnetic devices assume a position relative to one another in which the magnetic devices interact in a magnetically attractive manner, so that the attachment of the closure parts to one another is magnetically assisted.

[0026] When the closure device is opened, the magnetic devices are also moved relative to each other, moving away from each other along the opening direction. Thus, any magnetic attraction between the magnetic devices is weakened or even reversed into magnetic repulsion. The closure parts can thus be easily removed from each other after a relative movement along the opening direction.

[0027] In one embodiment, the first closure part and the second closure part can be loaded relative to each other in the closed position along a load direction that differs from the closing direction and the opening direction. The closure device can be designed, for example, as a webbing closure, on which, when loaded as intended, a load introduced by straps acts along a defined load direction. The load direction differs from the closing direction and also from the opening direction. For example, the load direction is approximately perpendicular to the closing direction and also perpendicular to the opening direction.

[0028] For example, a strap receptacle for attaching a strap can be arranged on each of the closure parts so that straps can be connected to one another via the closure device.

[0029] In one embodiment, the mounting element has a closing section that, in the mounted position, is flush with an outer side of the first housing part. In the mounted position of the first closure part, the mounting opening is thus closed to the outside by the mounting element, allowing an aesthetically pleasing appearance of the first closure part to be created.

[0030] In one embodiment, the housing part of the first closure part is molded in one piece. The housing part of the first closure part can be formed, for example, as a plastic molded part, for example, as an injection-molded plastic part. To complete the first closure part, the first magnetic device and the spring locking element are mounted on the housing part via the mounting element, so that in the assembled position of the first closure part, the spring locking element and the first magnetic device are positioned on the housing part as intended and can perform their intended function of connecting the closure parts to one another.

[0031] In one embodiment, the mounting element has a receiving opening for receiving the first magnetic device. The receiving opening can, for example, be formed in a base of the mounting element. For example, the receiving opening can be accessible on a first side of the mounting element, so that the first magnetic device can be inserted into the receiving opening on this first side for installation. In contrast, the spring locking element can be arranged on a second side of the mounting element facing away from the first side, in order to mount the first magnetic device and the spring locking element on the housing part by inserting the mounting element into the mounting opening of the housing part.

[0032] The first magnetic device can, for example, be formed by a cylindrical magnetic element. The receiving opening on the mounting element is shaped complementarily to the first magnetic device, so that the first magnetic device can be received in the receiving opening of the mounting element.

[0033] In one embodiment, the housing part has a plug-in opening. In the assembled position, the spring locking element, viewed along an axis pointing in the closing direction, is arranged in a space within the housing part that is aligned with the plug-in opening, such that the locking piece can be brought into engagement with the spring locking element by insertion into the plug-in opening. The locking parts are at least approximately and at least over a final section of the path when the locking parts are placed against one another along the axis, so that the locking piece and the spring locking element slide into engagement with one another along the axis.The spring locking element is arranged in the region of the plug-in opening of the housing part in such a way that, in the mounted position of the first closure part, the locking piece of the second closure part can be inserted along the axis into the plug-in opening of the housing part and the locking piece thereby comes into engagement with the spring locking element placed in the region of the plug-in opening.

[0034] In the closed position, the locking piece and the spring locking element are in engagement with each other, so that the locking parts are fixed to each other along the axis (and thus along the closing direction) and cannot be separated from each other as long as the engagement between the locking piece and the spring locking element is not canceled by a relative movement along the opening direction.

[0035] In one embodiment, the first magnetic device and the second magnetic device interact in a magnetically attractive manner along the axis. When the locking parts are placed against each other, the locking parts are thus attracted toward each other along the axis, so that the locking piece automatically engages the spring locking element along the axis, thus connecting the locking parts.

[0036] In the closed position, the first magnetic device and the second magnetic device can be aligned with each other along the axis and, for example, each arranged concentrically to the axis. However, it is also conceivable for the first magnetic device and the second magnetic device to be transversely offset relative to each other in the closed position, so that in the closed position, the locking parts are (also) magnetically acted upon by force transversely to the closing direction, in order, for example, to load the locking parts in the direction of engagement between the locking piece and the spring locking element, counter to the opening direction.

[0037] In one embodiment, to open the closure device, the locking piece can be moved out of the plug-in opening along the opening direction in order to disengage the locking piece and the spring locking element from one another. The closure device is closed by inserting the locking piece in the closing direction into the plug-in opening of the housing part of the first closure part, thus causing the locking piece to engage with the spring locking element on the housing part. The plug-in opening is open laterally, namely in the opening direction, so that the locking piece can be disengaged from the plug-in opening and thus from the spring locking element by lateral movement in the opening direction.

[0038] The closure device can be opened by moving the first closure part and the second closure part as a whole relative to each other. However, it is also conceivable and possible for only a part of the first closure part and / or the second closure part to be moved for opening.

[0039] In one embodiment, the spring locking element has a first latching section and the blocking piece has a second latching section. The first latching section and the second latching section engage with one another in the closed position to hold the first closure part and the second closure part against one another. In particular, a positive connection can be established via the latching sections, so that the closure parts are held against one another along the closing direction via the positive engagement of the blocking piece with the spring locking element. The blocking piece of the second closure part can, for example, have the form of a pin protruding from a body of the second closure part along the closing direction. The second latching section protrudes radially outwards to the closing direction and in this way enables engagement with the spring locking element of the first closure part.

[0040] In contrast, the first latching portion of the spring locking element of the first closure part can, for example, protrude radially inwards (with respect to the closing direction) in order to thereby establish engagement of the spring locking element with the locking piece in the closed position.

[0041] In one embodiment, the spring locking element is designed as a rigid element and is spring-loaded relative to the housing via an elastic spring element, so that the spring locking element can elastically deflect when the closure parts are placed against one another and, when the closure parts are placed against one another, can snap into a locking position in order to fix the closure parts to one another along the closing direction by engagement with the locking piece.

[0042] In another embodiment, the spring locking element is inherently elastically shaped and is elastically deformable for locking with the locking piece. To establish the connection between the locking parts, the spring locking element can be elastically deflected by elastic deformation, thereby snapping into engagement with the locking piece of the second locking part and thus establishing a connection between the locking parts through engagement with the locking piece.

[0043] In one embodiment, the spring locking element has at least one leg that can be elastically deflected transversely to the closing direction. The first locking portion is preferably formed on the at least one leg, so that a locking connection with the locking piece and thus between the closure parts can be established via the at least one elastically deflectable leg.

[0044] For example, the spring locking element has two legs that can be elastically deflected transversely to the closing direction and that, in the closed position, accommodate the locking piece between them. The spring locking element can, for example, have a C-shape when viewed in a plane perpendicular to the closing direction. A first locking section is preferably formed on each of the legs so that a positive connection can be established between the closure parts by engagement of the legs with the locking piece. In the closed position, the legs encompass the locking piece so that the engagement of the legs with the locking piece holds the closure parts together and the closure parts are thus fixed to one another along the closing direction.

[0045] In one embodiment, the legs are integrally connected to one another via a connecting section and are elastically deflectable relative to the connecting section. A locking section, for example, is also formed on the connecting section, so that the connecting section also contributes to engagement with the locking piece.

[0046] The connecting section is supported, for example, on the mounting element (if the spring locking element is to be mounted together with the mounting element on the housing part of the first closure part). The connecting section can be fixedly attached to the mounting element. However, the legs of the spring locking element are elastically attached to the mounting element and thus, in the mounted position of the first closure part, can be deflected relative to the housing part, so that the legs can establish a snap-in connection with the locking piece of the second closure part when the closure device is mounted as intended.

[0047] The spring locking element can be attached to the mounting element as a separate element in order to mount the spring locking element together with the mounting element on the housing part of the first closure part. In another embodiment, however, the spring locking element can also be formed integrally with the mounting element.

[0048] In one embodiment, the mounting element has a base extending transversely or obliquely to the closing direction and a raised portion protruding relative to the base. The base extends along a plane oriented transversely or obliquely to the closing direction. A raised portion is formed on the base, within which, for example, the first magnetic device is accommodated and which protrudes from the base toward the other, second closure part.

[0049] The raised portion can, for example, form a contact surface for the locking piece in the closed position. When the locking pieces are brought together, the locking piece of the second closure part is pulled toward the first closure part along the closing direction in such a way that the locking piece is brought closer to the contact surface on the raised portion and, for example, rests against the contact surface in the closed position, so that the closure pieces assume a defined position relative to each other.

[0050] In one embodiment, the spring locking element extends partially around the raised portion. For example, the legs of the spring locking element can engage around the raised portion, so that the spring locking element (at least if it is formed as a separate element from the mounting element) is centered on the mounting element via the raised portion. The raised portion can, for example, be aligned with the plug-in opening formed in the housing part, for example, by the raised portion being arranged concentrically with the plug-in opening in the mounted position of the first closure part.

[0051] To assemble the first closure part, the mounting element is inserted, in particular pushed, in the assembly direction into the mounting opening of the housing part of the first closure part. In the assembled position, the mounting element is firmly and immovably connected to the housing part, so that the position of the mounting element on the housing part of the first closure part is not changed when the closure device is handled as intended. In the assembled position, the mounting element can be firmly connected to the housing part, for example via a screw connection, a rivet connection, an adhesive connection, a weld connection, a clamp connection, or a form-fitting connection, in particular by locking.

[0052] In one embodiment, the mounting element has at least one locking element that is locked to the housing part in the mounted position of the first closure part. In the mounted position, the locking element of the mounting element engages, for example, with a housing section of the housing part, thereby creating a positive connection between the mounting element and the housing part, for example, a connection that cannot be easily removed without interference.

[0053] The locking element secures the mounting element relative to the housing part, particularly counter to the mounting direction, so that the mounting element cannot be removed from the mounting opening of the housing part counter to the mounting direction. In one embodiment, the mounting element has several locking elements that create a locking connection between the mounting element and the housing part at different locations. The locking elements can be configured, for example, as locking hooks, locking pins, or other locking elements that create a positive locking connection with the housing part in the mounted position.

[0054] A closure device of the type described can serve, for example, as a closure for bags, backpacks, suitcases, or other containers. A closure device of the type described can, for example, provide a strap closure for a backpack or for a helmet, in particular a sports helmet, for example a bicycle helmet or a ski helmet.

[0055] A closure device of the type described can in principle serve as a closure for connecting any objects to one another.

[0056] According to a further aspect, a method for assembling a closure device comprises: assembling a first closure part by inserting a mounting element together with a first magnetic device and / or a spring locking element into a mounting opening of a housing part in a mounting direction different from a closing direction and immovably connecting it to the housing part, and providing a second closure part which has a locking piece and a second magnetic device, wherein the first closure part, which is in an assembled position, and the second closure part can be placed against one another along the closing direction to close the closure device,are held together in a closed position by engagement of the locking piece with the spring locking element along the closing direction and can be released from each other to open the locking device by a relative movement along an opening direction different from the closing direction.

[0057] The advantages and advantageous embodiments described above for the closure device are also applicable analogously to the method, so that reference should be made to the preceding explanations in this regard.

[0103] Fig. 1A, 1B to 4A-4H show an embodiment of a closure device 1 having a first closure part 2 and a second closure part 3, which can be placed against one another along a closing direction X and are connected to one another in a closed position shown in Fig. 2A-2H. By a relative movement along an opening direction Y, the closure parts 2, 3 can be separated from one another, so that in an open position shown in Fig. 3A-3H, the closure parts 2, 3 are separate from one another and assemblies assigned to the closure parts 2, 3 are not connected to one another.

[0104] In the illustrated embodiment, the first closure part 2 has a housing part 20, on which a spring locking element 21 and a first magnetic device 22 in the form of a permanent magnet are mounted via a mounting element 23. In an assembled position, the spring locking element 21 and the first magnetic device 22 are arranged in the region of a plug-in opening 201 of the housing part 20, so that the closure parts 2, 3 can be attached to one another along an axis A pointing along the closing direction X by inserting a locking piece 31 of the second closure part 3 along the axis A into the plug-in opening 201 and thus engaging the spring locking element 21 on the housing part 20.

[0105] The locking piece 31 is formed on a housing part 30 of the closure part 3 and protrudes as a pin from a base 301 in the region of a slot 300 provided by the housing part 30. A locking section 310 is formed on the locking piece 31, which projects radially outwardly with respect to the axis A and is connected to associated locking sections 210 on legs 211 of the spring locking element 21 on the first closure part

[0106] 2 can be engaged.

[0107] In a receiving opening 304 concentric with the locking piece 31, a second magnetic device 32 in the form of a permanent magnet is arranged on the second closure part

[0108] 3. In the mounted position, the receiving opening 304 is closed to the outside by a cover element 303.

[0109] The magnetic devices 22, 32 point towards each other with unlike poles and thus are magnetically attractive to each other, so that the closure parts 2, 3 are magnetically attracted to each other when the closure parts 2, 3 are placed against each other and the closing of the closure device 1 is thus magnetically supported.

[0110] The magnetic attraction forces act in particular along the axis A, so that the locking piece 31 of the second closure part 3 is pulled along the axis A in the closing direction X into engagement with the plug-in opening 201 and the spring locking element 21 of the first closure part 2 received therein when the closure device 1 is closed.

[0111] The spring locking element 21 has two legs 211 that are integrally connected to one another via a connecting section 212 and that carry radially inwardly facing locking sections 210. A locking section 210 is formed on each leg 211 and also on the connecting section 212. In the closed position, the locking sections 210 engage with the locking section 310 of the locking piece 31, so that a positive connection is established and the closure parts 2, 3 are held together in a positive-locking manner along the closing direction X.

[0112] Fig. 3A-3H show the closure device 1 in an open position with the closure parts 2, 3 separated. To close the closure device 1, the closure parts 2, 3 are brought closer together along the closing direction X, so that the locking piece 31 of the closure part 3 is inserted along the axis A into the plug-in opening 201 of the housing part 20 of the closure part 2 and engages with the spring locking element 21 inside the housing part 20, as can be seen from Fig. 2A-2H, which show the closure device 1 in the closed position. In the closed position, the locking section 310 of the locking piece 31 is in positive engagement with the locking sections 210 on the legs 211 and the connecting section 212 of the spring locking element 21, so that the closure parts 2, 3 are positively secured to one another along the axis A and thus along the closing direction X.

[0113] A belt attachment 202, 302 is formed on each closure part 2, 3, via which a belt can be attached to the respective associated closure part 2, 3. The closure device 1 is thus designed as a belt fastener. When used as intended, a load acts between the closure parts 2, 3 along a load direction L, exerting a tensile force on the belts attached to the belt attachments 202, 302.

[0114] Due to the engagement of the locking piece 31 in the plug-in opening 201 in the closed position, the locking parts 2, 3 are also fixed to one another along the load direction L which is approximately perpendicular to the closing direction X.

[0115] To open the closure direction 1, the closure parts 2, 3 can be moved relative to one another along the opening direction Y perpendicular to the closing direction X, in order to disengage the locking piece 31 from the spring locking element 21 in the opening direction Y. The plug-in opening 201 of the housing part 20 is open laterally in the opening direction Y, as can be seen, for example, from Fig. 1 B. Likewise, the spring locking element 21 is open in the opening direction Y, so that the locking piece 31 can be disengaged from the spring locking element 21 in the opening direction Y and also disengaged from the plug-in opening 201, in order to separate the closure parts 2, 3 from one another and thus open the closure device 1.

[0116] Due to the movement of the closure parts 2, 3 relative to each other along the opening direction Y, the magnetic devices 22, 32 are also moved relative to each other, so that the magnetic devices 22, 32 are sheared off tangentially from each other. Due to the relative movement of the magnetic devices 22, 32, the magnetic attraction forces between the magnetic devices 22, 32 also weaken, so that the closure parts 2, 3 can be easily separated from each other.

[0117] In the illustrated embodiment, the first magnetic device 22 is received in a receiving opening 231 in the region of a base 234 of a body 230 of the mounting element 23. The base 234 extends along a plane extending transversely to the closing direction X. The receiving opening 231 is accessible on a first side facing away from the spring locking element 21, so that the magnetic device 22 can be joined to the receiving opening 231 on the first side.

[0118] On a second side facing away from the first side, the spring locking element 21 is arranged on the mounting element 23 such that the legs 211 of the spring locking element 21 engage around a raised portion 232 that projects relative to the base 234. The legs 211 are elastically adjustable transversely to the closing direction X to spread the spring locking element 21 in a plane perpendicular to the closing direction X. The connecting portion 212 is supported on the mounting element 23 and, for example, is fastened to the mounting element 23.

[0119] The raised portion 232 provides a contact surface against which the locking piece 31 rests in the closed position, as can be seen from Fig. 2F.

[0120] The locking piece 31 can slide along the raised portions 232 in order to open the closure device 1 by relative movement of the closure parts 2, 3 along the opening direction Y.

[0121] A closing section 233 is formed on the mounting element 23, which, in the mounted position of the first closure part 2, closes the mounting opening 200 to the outside and is flush with an outer side of the housing part 20 of the closure part 2, as can be seen in particular from Fig. 2B.

[0122] In the illustrated embodiment, the first magnetic device 22 and the spring locking element 21 are arranged on the mounting element 23 in a pre-assembly position, shown in Fig. 4A-4H, wherein in the pre-assembly position the mounting element 23 is separate from the housing part 20 of the first closure part 2. To assemble the first closure part 2, the mounting element 23 is pushed into the mounting opening 200 in an assembly direction M, which is directed parallel to the opening direction Y, so that the first magnetic device 22 and the spring locking element 21 are introduced into the interior of the housing part 20 and reach a position within the housing part 20 that is aligned with the plug-in opening 201 and concentric with the axis A, as can be seen from the sectional views according to Fig. 2F and 2H, illustrating the closure device 1 in the closed position.

[0123] In the assembled position, the mounting element 23 is locked to the housing part 20 via a locking element 235 and is thus fixed to the housing part 20 opposite to the assembly direction M. The locking element 235 is designed as a hook and engages behind a housing section 203 in the assembled position, as can be seen from Fig. 2, so that a positive connection, for example one that cannot be released non-destructively, is created between the mounting element 23 and the housing part 20 and, in the assembled position, the mounting element 23 is fixed to the housing part 20 in a stationary and positionally fixed manner.

[0124] When handled as intended to open and close the locking device 1, the mounting element 23 remains immovable on the housing part 20.

[0125] In the illustrated embodiment, locking elements 238 in the form of locking pins are formed on the closing section 233, which in the mounted position engage with associated locking openings 204 on the housing part 20 and create an additional locking connection between the mounting element 23 and the housing part 20.

[0126] The fact that the first magnetic device 22 and the spring locking element 21 are mounted via the mounting element 23 results in simplified assembly. Thus, the spring locking element 21 and the magnetic device 22 can be placed on the housing part 20 of the first closure part 2 in a single assembly step. By inserting the mounting element 23 into the housing part 20, they are precisely positioned within the housing part 20 in alignment with the plug-in opening 201. The housing part 20 can thus be manufactured in one piece.

[0127] In the assembled position, the mounting opening 200 is flush closed by the closing portion 233 of the mounting element 23, allowing an aesthetically pleasing appearance of the first closure part 2. In the illustrated embodiment, the spring locking element 21 is formed by a plastic part, for example, a plastic injection-molded part, and is attached to the mounting element 23 as a separate component.

[0128] In another embodiment, the spring locking element 21 can also be formed integrally and in one piece with the mounting element 23, in which case, for example, the connecting portion 212 merges integrally into the body 230 of the mounting element 23 and the legs 211 can be elastically deflected relative to the connecting portion 212 for spreading the spring locking element 21.

[0129] In a further embodiment illustrated in Figs. 5A, 5B to 12A, 12B, a closure device 1 comprises two closure parts 2, 3, which, as in the previously described embodiment, can be placed against one another along a closing direction X in order to close the closure device 1. The closure parts 2, 3 can be moved relative to one another along an opening direction Y perpendicular to the closing direction X in order to separate the closure parts 2, 3 from one another and thus open the closure device 1.

[0130] In the illustrated embodiment, a first closure part 2 has a housing part 20 which forms a mounting opening 200 and a plug-in opening 201, as can be seen from the exploded views according to Figs. 5A, 5B and 6A, 6B. In an assembled position of the first closure part 2, a mounting element 23 is received in the mounting opening 200, on which a first magnetic device 22 and a spring locking element 21 are arranged such that the magnetic device 22 and the spring locking element 21 come to lie in the region of the plug-in opening 201 in the interior of the housing part 20, as can be seen, for example, from Figs. 7A-7F, illustrating the closure device 1 in the closed position.

[0131] In the illustrated embodiment, the spring locking element 21 is formed from a sheet metal part, for example, made of spring steel. The spring locking element 21 has two legs 211, which form locking sections 210 through their inner, mutually facing edges and are integrally and integrally connected to one another via a connecting section 212 bent over to form the legs 211.

[0132] The legs 211 extend flatly along a plane perpendicular to the closing direction X. In this plane, the legs 211 are elastically adjustable relative to the connecting section 212 bent by 90°, so that the legs 211 can be spread apart with the locking sections 210 formed thereon, particularly when the closure parts 2, 3 are attached to one another.

[0133] This results in a flat design of the closure device 1, in which in particular the spring locking element 21 on the first closure part 2 does not contribute significantly to the overall height.

[0134] The spring locking element 21 is supported on the mounting element 23 via the connecting section 212. Engagement sections 213 in the form of bent tabs on the legs 211 engage with engagement openings 236 on the body 230 of the mounting element 23 and limit a spreading movement of the legs 211, thus counteracting excessive loading on the legs 211 of the spring locking element 21.

[0135] In the region of a bottom 234 of a clearance of the mounting element 23, a raised portion 232 is formed, which projects relative to the bottom 234 and creates a contact surface for a locking piece 31 of the other, second closure part 3.

[0136] On a side facing away from the spring locking element 21, the mounting element 23 forms a receiving opening 231 in which the first magnetic device 22 is received.

[0137] For mounting the first closure part 2, the mounting element 23 can be inserted into the mounting opening 200 of the housing part 20 of the closure part 2 in a mounting direction M perpendicular to the closing direction X and also to the opening direction Y. In the mounted position, as can be seen, for example, from Figs. 7A to 7F and from the sectional views according to Figs. 8C, 9C and 11B, the mounting opening 200 is closed to the outside by a closing section 233 of the mounting element 23, in that the closing section 233 is flush with an outer side of the housing part 20 in the region of the mounting opening 200.

[0138] In the assembled position, the mounting element 23 is locked to the housing part 20 via locking elements 235, in that the locking elements 235 engage behind associated housing sections 203 of the housing part 20, as can be seen, for example, in Figs. 7F and 9C. In addition, a locking element 238 in the form of a locking pin engages with an associated locking opening 204 of the housing part 20 (see, for example, Fig. 6B), thus creating an additional locking connection on the closing section 233.

[0139] On a housing part 30 of the second closure part 3, a locking piece 31 is formed in the form of a pin projecting axially along the closing direction X relative to a base 301 of a slot 300. A locking portion 310 protrudes radially outward on the locking piece 31.

[0140] In the closed position, the locking piece 31 engages in the spring locking element 21 such that the latching portion 310 on the locking piece 31 engages positively with the latching portions 210 on the inner edges of the legs 21 1 of the spring locking element 21 and thereby a positive connection is established between the closure parts 2, 3, as can be seen from Fig. 7A-7F.

[0141] A second magnetic device 32 is accommodated in a receiving opening 304 on the rear side of the housing part 30, which magnetically interacts with the first magnetic device 22 of the first closure part 2.

[0142] To close the closure direction 1, the closure parts 2, 3 can be placed against one another along the closing direction X, so that the locking piece 31 is pulled along an axis A into engagement with the plug-in opening 201 and engages with the spring locking element 21. In the closed position, the locking piece 31 rests with a recessed contact surface 311 formed radially inside the latching section 310 against the raised section 232 of the mounting element 23 on the side of the first closure part 2, as can be seen from Fig. 7D, so that the closure parts 2, 3 assume a defined, centered position relative to one another.

[0143] As can be seen in particular from Fig. 12B, in the closed position of the closure device 1, the magnetic devices 22, 32 have a transverse offset relative to one another with respect to the axis A, which is defined by a cylinder axis of the substantially cylindrically shaped locking piece 31, which causes the second closure part 3 to be loaded counter to the opening direction Y into engagement with the spring locking element 21. Thus, the magnetic device 22 of the first closure part 2 is transversely offset relative to the axis A counter to the opening direction Y, so that a directional vector component of a magnetic attraction force between the closure parts 2, 3 acts counter to the opening direction Y and thus the closure part 3 is loaded counter to the opening direction Y in the direction of engagement with the spring locking element 21 relative to the closure part 2.

[0144] To open the closure device 1, the closure parts 2, 3 can be moved relative to each other along the opening direction Y. As a result, the locking piece 31 can be disengaged from the spring locking element 21 in the opening direction Y and moved laterally out of the plug-in opening 201 of the housing part 20. The closure parts 2, 3 are thus separated from each other and are in an open position, separated from each other.

[0145] With regard to the basic functionality of closing and opening the closure device 1, the embodiments according to Figs. 1A, 1B to 4A-4H and 5A, 5B to 12A, 12B are essentially identical, so that the description of one embodiment also applies analogously to the other embodiment.

[0146] The idea underlying the invention is not limited to the embodiments described above, but can also be implemented in other ways.

[0147] The mounting element can be connected to the housing part of the first closure part by one or more locking elements. Additionally or alternatively, other types of connection are also conceivable and possible, for example, a screw connection, a rivet connection, a clamp connection, an adhesive connection, a welded connection in the assembled position, or the like. Such a connection can be established, for example, after the mounting element has been inserted into the housing part of the first closure part for assembly.

[0148] The mounting direction in which the mounting element is to be inserted into the housing part for mounting the first closure part can be directed in the same direction as the opening direction, but can also differ from the opening direction, in particular can be directed perpendicularly or obliquely to the opening direction.

[0149] The opening direction and the mounting direction are each different from the closing direction, meaning they are neither aligned in the same direction nor opposite to the closing direction. The mounting direction and the opening direction can be perpendicular or diagonal to the closing direction. The opening direction can be linear or rotational. The mounting direction can be linear or follow a curved path.
