Description

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

Such a closure device known in-house comprises a first closure part which has a first plug-in section and a first magnet arrangement, and a second closure part which has a second plug-in section and a second magnet arrangement. A housing module comprises two plug-in openings, a third magnet arrangement and an actuating assembly, wherein the first closure part and the second closure part with the respective plug-in section can each be inserted into one of the plug-in openings for connection to the housing module. This takes place with magnetic attraction of the first magnet arrangement with the third magnet arrangement and the second magnet arrangement with the third magnet arrangement, so that the attachment of the closure parts to the housing module is supported magnetically. In a closed position, the closure parts are positively connected to the housing module and thus held on the housing module. The actuation assembly can be actuated to release the first closure part and the second closure part from the housing module, so that the closure parts can be removed from the housing module and the closure device can thus be opened.

Such a locking device can be used, for example, as a buckle on a stroller or on a child seat. A multi-strap connection can be provided via such a locking device, for example in that several straps can be connected to one another via the locking parts and the housing module.

A locking device for a multi-belt connection is for example from the subsequently published DE 10 2018 123 026 A1 known.

The object of the present invention is to provide a locking device that is comfortable to use, enables a secure and reliable connection in the closed position and is easy and inexpensive to manufacture.

This object is achieved by an object having the features of claims 1, 17 and 19.

Accordingly, the first closure part and the second closure part can be inserted into each of the plug-in openings.

Because the first closure part and the second closure part can be inserted into each of the plug-in openings, the first closure part and the second closure part can be designed as identical parts. This can simplify production and thus reduce production costs, with variable usability and also simple handling.

In one embodiment, the third magnet arrangement with a pole of the same name points towards the first plug-in opening and the second plug-in opening. The third magnet arrangement here acts magnetically attractively with the first magnet arrangement of the first closure part and with the second magnet arrangement of the second closure part, the first magnet arrangement and the second magnet arrangement each having a pole of the same name when the first closure part and the second closure part are attached to the housing module, for example point towards the third magnet arrangement. Because the third magnet arrangement with poles of the same name points towards the closure parts, closure parts of the same construction with the same magnet arrangements can be inserted into both plug-in openings, with magnetic attraction with the third magnet arrangement of the housing module.

The third magnet arrangement can point towards each of the closure parts with a single magnetic pole, for example with a north pole, in which case the first magnet arrangement of the first closure part and the second magnet arrangement of the second closure part each point with a south pole towards the third magnet arrangement and thus interact with the North Pole in a magnetically attractive manner.

Alternatively, the third magnet arrangement can also provide a pole arrangement in which, for example, a north pole and a south pole (and possibly further poles) are arranged one above the other or next to one another. In this case, the first closure part and the second closure part have the same pole arrangement towards the third magnet arrangement, i.e. they have the same arrangement of magnetic poles arranged one above the other or next to one another, so that the closure parts each interact magnetically attractively with the housing module.

The third magnet arrangement can be formed by one or more permanent magnets. In this case, the first and the second magnet arrangement of the first and the second closure part can also be formed by one or more permanent magnets or alternatively by a magnetic armature made of a ferromagnetic material.

The third magnet arrangement can alternatively be formed by a magnetic armature. In this case, the first magnet arrangement of the first closure part and the second magnet arrangement of the second closure part are each formed by one or more permanent magnets.

In one embodiment, the third magnet arrangement in the closed position is arranged between the first closure part and the second closure part such that the first closure part is arranged on a first side of the third magnet arrangement and the second closure part is arranged on a second side of the third magnet arrangement facing away from the first side . The third magnet arrangement is thus in a central position between the plug-in openings so that the closure parts can be brought closer to the third magnet arrangement on both sides, with magnetic attraction of the third magnet arrangement with the first magnet arrangement of the first closure part and the second magnet arrangement of the second closure part. Due to the interaction of the third magnet arrangement with the magnet arrangements of the closure parts, the attachment of the closure parts to the housing module is supported magnetically so that the closure of the closure device can preferably take place largely automatically, producing a positive connection between the closure parts and the housing module.

In one embodiment, the third magnet arrangement is arranged on the actuation assembly and is thus adjusted together with the actuation assembly when the actuation assembly is actuated. This makes it possible that when the actuation assembly is actuated to release the closure parts from the housing module, the magnet arrangement is also adjusted relative to the closure parts and the magnet arrangements arranged thereon, so that when the actuation assembly is actuated the magnetic attraction force of the third magnet arrangement with the magnet arrangements of the closure parts is also weakened and the Removal of the closure parts from the housing module is thus facilitated.

When the third magnet arrangement is adjusted relative to the closure parts, the magnetic attraction can possibly even be converted into magnetic repulsion due to a so-called edge effect. Magnetic repulsion thus results when magnets, which are magnetically attracting opposite each other with unlike poles in the closed position, are moved tangentially with their opposite pole faces when opening. If the magnets have at least approximately the same pole shape (ie the surfaces with which the poles face each other are essentially shaped identically) and if the magnets move a certain distance, e.g. about their width (measured in the opening direction) or slightly less than their width, shifted relative to each other along the opening direction and if the pole faces are kept parallel to each other (so that the magnets are roughly edge to edge, for example), there is a magnetic repulsion between the magnets, which reaches a maximum with further shifting and then slowly falls off.

The closure parts can be guided on the housing module via suitable guide devices, which makes it easier to attach the closure parts to the housing module and also prevents the closure parts from tilting relative to the housing module when the actuation assembly is actuated to release the closure parts.

In one embodiment, the housing module has a housing on which the actuating assembly is adjustably arranged. In order to release the first locking part and the second locking part from the housing module, the actuating assembly can be adjusted in an actuating direction towards the housing, for example by a user acting on the actuating assembly and pressing the actuating assembly into the housing like a push button. By actuating the actuation assembly, the positive connection between the housing module and the locking parts is canceled, so that the locking parts can be removed from the housing module and the locking device is thus opened.

In one embodiment, the actuation assembly is spring-biased towards the housing against the actuation direction. The actuation assembly is thus actuated against the spring force provided by the spring preload, for example by one or more spring elements. After actuation, the actuation assembly is returned to an initial position due to the spring preload, in which, when the closure parts are plugged onto the housing module again, the closure parts are locked with the housing module and the closure device can thus be closed again.

In one embodiment, the spring force provided by the spring preload exceeds a predetermined minimum force. The idea behind this is that the closure device should only be opened by certain users, for example adults, for example when used as a buckle on a stroller or a child's seat, whereas children should not open the closure device easily should be able to. The actuation of the actuation assembly should therefore require a minimum force that a child cannot easily apply. This minimum force can be set by dimensioning one or more spring elements that provide the spring preload of the actuation assembly. For example, the minimum force can be equal to or greater than 5 Newtons, preferably equal to or greater than 10 Newtons, more preferably equal to or greater than 20 Newtons or even equal to or greater than 50 Newtons.

In one embodiment, the first closure part with the first plug-in section and the second closure part with the second plug-in section for connecting to the housing module can each be plugged into one of the plug-in openings along a closing direction. The closing direction is here, for example, directed transversely to the actuation direction, the closing directions along which the closure parts can be plugged into the plug-in openings, located in a common plane or even collinear, but oriented in opposite directions. For example, the plug-in openings on the housing module are formed on diametrically opposite sides of the housing module, so that the locking parts with their plug-in sections can be plugged onto the housing module on the sides facing away from each other in order to lock with the housing module, with the attachment of the locking parts under magnetic attraction of the magnet arrangements Closure parts with the magnet arrangement of the housing module takes place.

In one embodiment, the first plug-in section and the second plug-in section each have a latching head for establishing a form-fitting connection with the housing module. The latching head can have at least one run-up bevel extending obliquely to the closing direction and obliquely to the actuating direction, which can be designed so that the latching head runs onto an associated locking section on the housing module when the respective plug-in section is inserted, thus establishing a positive connection between the plug-in section and the housing module becomes.

In one embodiment, the latching head has two run-up bevels which are formed on sides of the latching head facing away from one another. The run-up bevels are preferably directed mirror-inverted to the respective closing direction, so that the latching head has a wedge shape with run-up bevels on sides facing away from one another.

The latching head is designed, for example, mirror-symmetrical to a mirror-symmetrical plane directed perpendicular to the actuation direction. In general, each closure part can be formed essentially mirror-symmetrically to a mirror-symmetry plane directed perpendicular to the actuation direction.

In one embodiment, the actuation assembly has a locking element that forms locking sections which, in the closed position, are positively connected to the first plug-in section of the first closure part and to the second plug-in section of the second closure part. The locking sections, for example in the form of undercuts, serve to lock the plug-in sections to the housing module in the closed position so that the plug-in sections cannot be removed from the housing module against the respectively assigned closing direction, at least not without actuating the actuation assembly. In the closed position, the plug-in sections are thus locked to the actuation assembly, whereby the positive connection can be canceled by actuation of the actuation assembly and the plug-in sections can thus be removed from the housing module.

The locking element can be adjusted by actuating the actuation assembly, so that the locking sections can thereby be brought out of engagement from the first plug-in section and the second plug-in section.

The actuation assembly can, for example, have an actuation element, for example in the form of a lever, on which a user can act in order to actuate the actuation assembly. When the actuating element is actuated, the locking element is adjusted together with the actuating element and is thus operatively connected to the actuating element. Due to a spring preload of the actuation assembly, the actuation element and the locking element can be reset together against the actuation direction after actuation has taken place, so that the actuation element and the locking element return to an initial position in which locking with the closure parts can take place when they are inserted into the housing module . The locking element can be adjusted independently of the actuating element and movable relative to the actuating element when the locking parts are inserted into the plug-in openings of the housing module, so that the plug-in sections of the locking parts run onto the locking sections of the locking element, for example, and can come into positive engagement with the locking sections.

In one embodiment, the locking element is spring-preloaded with respect to a housing section of the housing module via a first spring element. The actuating element is on the other hand a second spring element opposite the The housing section of the housing module is spring-preloaded, the first spring element and the second spring element having different spring constants. Both the first spring element and the second spring element can, for example, be designed as compression springs, so that when the actuation element is actuated in the actuation direction, the first spring element and the second spring element are tensioned under pressure. The first spring element can be designed to be softer than the second spring element in that the first spring element has a smaller spring constant than the second spring element. The second spring element, via which the actuating element is spring preloaded with respect to the housing section, can be designed with a comparatively large spring constant, so that the spring preload of the actuating element relative to the housing via the second spring element is greater than the spring preload of the blocking element relative to the housing via the first spring element.

In this way, the locking element can be spring-preloaded in a comparatively soft manner with respect to the housing, while the actuating element is preloaded in a comparatively hard manner with respect to the housing via the second spring element.

When the actuating element is actuated to adjust the locking element to release the locking parts, the actuating element and the locking element are moved together so that the pretensioning force of the spring elements must be overcome together. The pre-tensioning force (determined in particular by the hard spring constant of the second spring element) can be dimensioned in such a way that the actuating element for releasing the locking device can only be actuated by overcoming a sufficient force, which is preferably dimensioned such that, for example, a child cannot use the actuating element can easily operate. In this way, the security against unintentional, unauthorized loosening of the locking device is increased.

In contrast, when the closure parts are plugged in, the locking element can be moved against the spring preload of the first spring element independently of the actuating element, the locking element being able to be deflected in a comparatively smooth manner due to the soft spring preload of the first spring element. This enables the locking parts to be plugged in with magnetic support via the magnet assemblies, whereby, due to the soft spring preload, the attachment of the locking parts and the engagement with the locking element can be effected automatically by the magnetic attraction, with automatic deflection of the locking element due to the magnetic attraction.

This aspect can also be used independently of whether the closure parts can be plugged into both the first plug-in opening and the second plug-in opening.

A closure device in a general configuration comprises a first closure part which has a first plug-in section and a first magnet arrangement, a second closure part which has a second plug-in section and a second magnet arrangement, and a housing module which has two plug-in openings, a third magnet arrangement and an actuation assembly . To connect to the housing module, the first closure part with the first plug-in section can be inserted into one of the plug-in openings and into one of the plug-in openings with magnetic attraction of the first magnet arrangement with the third magnet arrangement and the second closure part with the second plug-in section under magnetic attraction of the second magnet arrangement with the third magnet arrangement Closed position positively connected to the housing module. The actuation assembly can be actuated to release the first closure part and the second closure part from the housing module. It is provided here that the actuation assembly has a locking element which has locking sections which, in the closed position, are positively connected to the first plug-in section of the first closure part and to the second plug-in section of the second closure part, the actuation assembly having an actuation element that can be actuated by a user, wherein the locking element is moved together with the actuating element when the actuating element of the actuating assembly is actuated and is adjustable relative to the actuating element when the first closure part and the second closure part are inserted into each of the plug-in openings, the locking element via a first spring element opposite a housing section of the housing module and the The actuating element is spring-biased by a second spring element with respect to the housing section of the housing module, the first spring element and the second spring element having different spring constants exhibit.

The aspects described above can be freely combined with the closure device of this type, so that reference should be made to the preceding statements in this regard.

In one embodiment, the actuation assembly has an active element on which run-up bevels are formed which, when the actuation assembly is actuated, deflects force on the first plug-in section and the second plug-in section act to help release the first plug-in section and the second plug-in section. The active element can for example be firmly connected to the actuation element of the actuation assembly and is moved in the actuation direction when the actuation assembly is actuated. In this case, for example, an operative connection with the blocking element can be established via the active element, so that when the actuation assembly is actuated in the actuation direction, the blocking element is moved together with the active element in the actuation direction. Due to the fact that run-up bevels are formed on the active element, the active element acts on the plug-in sections of the closure parts when the closure parts are plugged into the housing module, so that they are conveyed out of the plug-in openings against the respectively assigned closing direction, so that the closure device is released when the actuating assembly is actuated is supported by the closure parts being pressed out of the plug-in openings against the respectively assigned closing direction. The closure parts can thus be easily removed from the housing module when the actuation assembly is actuated.

The run-up bevels can be firmly connected to the active element or be formed by elastically deformable elements which are gradually biased during the actuation of the actuating element and, from a predetermined point of actuation, push the closure parts out of the plug-in openings.

The object is also achieved by a closure device with a first closure part that has a first plug-in section and a first magnet arrangement, a second closure part that has a second plug-in section and a second magnet arrangement, and a housing module that has two plug-in openings, a third magnet arrangement and a Having actuation assembly. To connect to the housing module, the first closure part with the first plug-in section can be inserted into one of the plug-in openings and into one of the plug-in openings with magnetic attraction of the first magnet arrangement with the third magnet arrangement and the second closure part with the second plug-in section under magnetic attraction of the second magnet arrangement with the third magnet arrangement Closed position positively connected to the housing module, wherein the actuation assembly can be actuated to release the first closure part and the second closure part from the housing module. It is provided that the actuation assembly has an active element on which run-up bevels are formed which, when the actuation assembly is actuated, act in a force-diverting manner on the first plug-in section and the second plug-in section in order to support the release of the first plug-in section and the second plug-in section.

The closure device can be combined with the previously described aspects and different configurations, so that reference should be made to the preceding statements in this regard.

The active element can for example be firmly connected to the actuation element of the actuation assembly and is moved in the actuation direction when the actuation assembly is actuated. For example, an operative connection with a blocking element can be established via the active element, so that when the actuation assembly is actuated in the actuation direction, the blocking element is moved together with the active element in an actuation direction. Due to the fact that run-up bevels are formed on the active element, the active element acts on the plug-in sections of the closure parts when the closure parts are plugged into the housing module, so that they are conveyed out of the plug-in openings against the respectively assigned closing direction, so that the closure device is released when the actuating assembly is actuated is supported by the closure parts being pressed out of the plug-in openings against the respectively assigned closing direction. The closure parts can thus be easily removed from the housing module when the actuation assembly is actuated.

The run-up bevels can also be firmly connected to the active element or be formed by elastically deformable elements which are gradually pretensioned during the actuation of the actuating element and, from a predetermined point of actuation, push the closure parts out of the plug-in openings.

In one embodiment, a belt connection for fastening a belt is arranged on the first closure part and on the second closure part. A belt connection can also be provided on the housing module so that three belts can be connected to one another via the first closure part, the second closure part and the housing module.

In addition, a belt connection element with a further belt connection for fastening a further belt can be arranged on the first closure part and / or on the second closure part (each). Such a belt connection element can be arranged, for example, on a body of the respectively assigned closure part in that the body reaches through an opening in the belt connection element. Such Arrangement of the belt connection element on the associated closure part can enable a releasable hold of the belt connection element on the closure part, wherein in the closed position of the closure device the belt connection element is firmly connected to the housing module via the closure part.

If a belt connection element with a further belt connection is arranged on each of the two fastening parts, five belts can be connected to one another via the fastening device.

A locking device of the type described can be used, for example, on a stroller or a child seat to fasten belts to one another. Such a locking device can generally be used wherever it is necessary to fasten several assemblies to one another, for example to fasten several straps, bands, straps, ropes or other elements to one another.

The locking heads are in the closed position 310 , 410 , as in particular from the sectional view according to 2C visible, form-fitting with the locking sections 241 , 242 of the locking element 24 connected, so that the closure parts 3 , 4th with the housing module 2 are locked. The actuation assembly 28 is in the closed position in an upper position in that by the housing parts 20th , 21st formed housing, due to the spring preload of the spring elements 26th , 27 .

In this upper position is - viewed along the actuation direction B. - the magnet arrangement 25th the actuation assembly 28 essentially at the same level as the magnet assemblies 35 , 45 the closure parts 3 , 4th , as shown in the sectional view 2 B can be seen. The magnet arrangement 35 shows how 2 B can be seen, with poles of the same name (in this case the south pole S) facing outwards, with the magnet arrangements 35 , 45 the closure parts 3 , 4th each with the same pole (in this case a north pole N) towards the magnet arrangement 35 point. The magnet arrangements 35 , 45 the closure parts 3 , 4th are thus each magnetically attractive to the magnet arrangement 35 of the housing module 2 across from.

In the illustrated embodiment, the closure parts 3 , 4th designed as identical parts. In particular, the closure parts 3 , 4th at their plug-in sections 31 , 41 shaped identically, with the magnet arrangements 35 , 45 with poles of the same name towards the housing module 2 point (if the closure parts 3 , 4th to the housing module 2 are set). This enables the closure parts 3 , 4th into each of the plug-in openings 200 , 201 can be plugged in and any closure part 3 , 4th thus also in the other plug-in opening 201 , 200 can be plugged in.

The formation of the closure parts 3 , 4th the use of identical parts enables simple handling and also simple production, while reducing tool costs and, moreover, simplifying assembly, in which no special attention is paid to the correct positioning of the closure parts 3 , 4th must be laid.

Looking at the plug-in sections 31 , 41 , especially the locking heads 310 , 410 , are the locking parts 3 , 4th also mirror-inverted to one perpendicular to the direction of actuation B. extended mirror plane of symmetry, which allows the closure parts 3 , 4th in a mirror-inverted manner to the housing module 2 to apply.

Referring now to the views of FIG 3A-3C to 6A-6C , a user presses to open the locking device 1 on the actuator 22nd to the actuator 22nd in the direction of actuation B. into that through the housing parts 20th , 21st to press in the formed housing, as shown in the transition from 3A-3C towards 4A-4C can be seen. This becomes the active element 23 together with the actuating element 22nd in the direction of actuation B. moves and acts on the locking element 24 a so that the locking sections 241 , 242 of the locking element 24 in the direction of actuation B. disengaged from the locking heads 310 , 410 the closure parts 3 , 4th to be brought.

In addition, the magnet arrangement 25th attached to the active element 23 is arranged in the direction of actuation B. adjusted and thus by the magnet arrangements 35 , 45 the closure parts 3 , 4th removed so that the magnetic attraction force between the locking parts 3 , 4th and the housing module 2 is weakened (and possibly turned around due to an edge effect).

The locking element 23 points to the locking parts 3 , 4th facing sides ramp bevels 231 , 232 on, which serve with the approach slopes 311 , 411 on the top of the locking heads 310 , 410 the closure parts 3 , 4th cooperate to make the closure parts 3 , 4th when the actuation assembly is actuated 28 against the respectively assigned closing direction X1 , X2 from the plug-in openings 200 , 201 come out like this in the transition from 3A-3C towards 4A-4C can be seen. The locking parts 3 , 4th are thus mechanically at least a certain distance out of the plug-in openings when opening 200 , 201 pressed out so that the locking parts 3 , 4th , as in 5A-5C shown, in a simple manner from the housing module 2 can be removed.

After actuation, the actuation assembly 28 due to the spring preload of the spring elements 26th , 27 automatically into a Initial position postponed in which the area section 220 essentially flush with an upper side of the housing part 21st is arranged and the locking element 24 again occupies a position in which the closure parts 3 , 4th when repositioning the housing module 2 can be locked out like this 6A-6C can be seen.

When attaching the locking parts 3 , 4th to the housing module 2 how out 7A-7C visible, get the plug-in sections 31 , 41 with the locking heads formed on it 310 , 410 in annex with the blocking sections 241 , 242 of the locking element 24 , with the bevels 312 , 412 on the locking heads 310 , 410 on run-up slopes on the plug-in sections 241 , 242 run up and thereby the locking element 24 so far in the actuation direction B. deflect that the locking heads 310 , 410 in the respective assigned closing direction X1 , X2 at the blocking sections 241 , 242 can be moved past and in positive engagement with the locking sections 241 , 242 arrive, as shown in the views corresponding to the closed position 3A-3C can be seen.

When establishing the closed position, the locking element is 24 independent of the actuator 22nd and the active element 23 adjustable, with a relative movement of the coupling elements 234 to the engagement sections 243 so that the locking element 24 against the spring preload of the spring elements 27 can be deflected and the closure parts 3 , 4th with their plug-in sections 31 , 41 thus in a form-fitting connection with the locking element 24 can be brought.

Because the spring elements 27 are relatively soft, the deflection of the locking element 24 when the closure parts 3, 4 are attached, relatively smooth-running with little force, so that the magnetic forces of attraction of the magnet arrangements 25th , 35 , 45 automatic deflection of the locking element 24 when attaching the closure parts 3.4 can cause.

Due to the design and orientation of the magnet arrangements 25th , 35 , 45 can the locking parts 3 , 4th in each plug-in opening 200 , 201 be plugged in. This is achieved, among other things, as schematically shown in 8th shown that the magnet assemblies 35 , 45 at the plug-in sections 31 , 41 the closure parts 3 , 4th with poles of the same name (in this case the north pole N) to the magnet arrangement 25th on the active element 23 of the housing module 2 point and each closure part 3 , 4th thus from each side to the magnet arrangement 25th can be applied, each with magnetic attraction between the magnet arrangements 25th , 35 , 45 .

In another embodiment, the magnet arrangements 25th , 35 , 45 as shown schematically in 9 is shown, also each have a plurality of magnetic poles N, S, which lead to a respectively assigned, different magnet arrangement 25th , 35 , 45 point. So can with the magnet arrangement 25th of the housing module, two magnetic poles N, S can be arranged one above the other, in which case the closure parts 3 , 4th same magnet arrangements 35 , 45 have, in which (exactly reversed) magnetic poles N, S are arranged one above the other. Again, each closure part 3 , 4th in every plug-in opening 200 , 201 are inserted, each with magnetic attraction to the magnet assembly 25th of the housing module 2 .

In the embodiment according to 9 are the magnetic poles N, S of the individual magnet arrangements 25th , 35 , 45 - viewed along the actuation direction B. - arranged one above the other. In an alternative embodiment, the magnet arrangements 25th , 35 , 45 as shown schematically in 10 is shown, also each have a plurality of magnetic poles N, S, which lead to a respectively assigned, different magnet arrangement 25th , 35 , 45 point and along a transverse to the actuation direction B. and across the closing directions X1 , X2 directed transverse direction are arranged side by side. Again, each closure part 3 , 4th in every plug-in opening 200 , 201 are inserted, each with magnetic attraction to the magnet assembly 25th of the housing module 2 .

Because the closure parts 3 , 4th also in particular at the plug-in sections 31 , 41 mirror symmetrical to one perpendicular to the direction of actuation B. directed mirror symmetry plane are formed, the closure parts 3 , 4th in one through the actuation direction B. and the closing direction X1 , X2 rotated by 180 ° and into the plug-in openings 200 , 201 on the different sides of the housing module 2 be plugged in. About the locking heads 310 , 410 and the bevels formed on both sides 311 , 312 , 411 , 412 can the plug-in sections 31 , 41 each with the run-up slopes on the blocking sections 241 , 242 and with the bevels 231 , 232 on the active element 23 work together.

The idea on which the invention is based is not restricted to the exemplary embodiments described above, but can also be implemented in other ways.

A locking device of the type described can be used in particular as a lock on a stroller or a child seat, but possibly also in another application, for example on a sports seat (rally seat) or anywhere where several assemblies are to be connected to one another at one point.
