Description

Closure device with two closure parts that can be connected to a housing module

Technical Field

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

Background

The closure device comprises a first closure part with a first plug-in section and a first magnet arrangement, and a second closure part with a second plug-in section and a second magnet arrangement. The housing module comprises two plug-in openings, a third magnet arrangement and an actuating assembly, wherein the first closing part and the second closing part can be inserted into in each case one plug-in opening by means of a corresponding plug-in section for connection to the housing module. This takes place with the first and third magnet arrangements and the second and third magnet arrangements magnetically attracted to one another, so that the magnetic assistance in the placement of the closure element on the housing module. In the closed position, the closure part is positively connected to the housing module and is held on the housing module. The operating assembly can be operated for releasing the first and second closure members from the housing module, so that the closure members can be taken out of the housing module and the closure device can be opened.

Such a closure device can be used, for example, as a buckle on a baby carriage or a child seat. Via such a closure device, a multi-band connection can be provided, for example, in the following manner: a plurality of straps can be interconnected via the closure member and the housing module.

Disclosure of Invention

The object of the invention is to provide a closure device which is comfortable to handle, can be securely and reliably connected in the closed position, and can be produced in this way in a simple and cost-effective manner.

This object is achieved by the subject matter having the features of claim 1.

The actuating assembly therefore comprises a locking element with a locking section which is connected in a form-fitting manner with the first plug section of the first closure part and the second plug section of the second closure part in the closed position, wherein the actuating assembly has an actuating element which can be actuated by a user, wherein the locking element moves together with the actuating element when the actuating element of the actuating assembly is actuated and can be adjusted relative to the actuating element when the first closure part and the second closure part are inserted into in each case one plug opening.

The latching section of the latching element, for example in the form of a lateral recess, serves to lock the plug section in the closed position relative to the housing module, so that the plug section cannot be removed from the housing module counter to the respectively associated closing direction, at least without operating the operating assembly. In the closed position, the plug section is thus locked with the operating assembly, wherein by operating the operating assembly the form-fitting connection is cancelled, and the plug section can be removed from the housing module.

The locking element can be adjusted by actuating the actuating assembly, so that the locking section can thus be disengaged from the first and second plug section.

The actuating element can be designed, for example, in the form of a pressing element, which can be acted upon by a user in order to actuate the actuating assembly. When the operating element is actuated, the blocking element is adjusted together with the operating element and is thus effectively connected to the operating element. Due to the elastic pretensioning of the actuating assembly, the actuating element and the blocking element can be reset together counter to the actuating direction after actuation has taken place, so that the actuating element and the blocking element return into an initial orientation in which locking can be achieved by means of the closure part when inserted into the housing module. In this case, the latching element can be adjusted independently of the actuating element and can be moved relative to the actuating element when the closure part is inserted into the plug-in opening of the housing module, so that the plug-in section of the closure part can, for example, come into contact with the latching section of the latching element and can be brought into positive engagement with the latching section.

In this case, the operating element can also be divided into two parts, which are in turn formed by two operating parts to be operated by the user. By dividing the actuating element into two actuating parts, for example, the blocking element can be actuated (for example, in the manner of a rocker arm), so that the blocking parts can be released separately and independently of one another from the housing module. By actuating the actuating part of the actuating element, the locking element can thus be actuated for unlocking the plug section of the associated closure part.

In one embodiment, the operating element can be locked via a locking device. In the locking position, the locking device locks the operating element relative to the housing module. The locking device can be unlocked, so that the operating element can be moved toward the housing module for adjusting the blocking element.

In one embodiment, the locking element is elastically pretensioned with respect to the housing section of the housing module via a first spring element. In contrast, the actuating element is elastically pretensioned with respect to the housing section of the housing module via a second spring element, wherein the first spring element and the second spring element have different spring constants. The first and second spring elements can be embodied, for example, as compression springs, so that when the actuating element is actuated in an actuating direction, the first and second spring elements are tensioned under pressure. The first spring element can in this case 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 actuating element is elastically pretensioned relative to the housing section by means of a second spring element, which can be designed to have a relatively large spring constant, so that the elastic pretension of the actuating element relative to the housing by means of the second spring element is greater than the elastic pretension of the blocking element relative to the housing by means of the first spring element.

In this way, the blocking element can be elastically pretensioned in a relatively soft manner with respect to the housing, while the actuating element is pretensioned in a relatively stiff manner with respect to the housing via the second spring element.

When the actuating element is actuated to adjust the blocking element in order to release the closing element, the actuating element and the blocking element move together such that the pretensioning force of the spring element can be overcome together. The pretensioning force (in particular determined by the hard spring constant of the second spring element) can be determined in such a way that the actuating element can only be actuated to release the closure device by overcoming a sufficient force, which is preferably determined in such a way that the actuating element cannot be easily actuated by a child, for example. In this way, security against accidental, unauthorized release of the closure is increased.

When the closing part is inserted, the blocking element can be moved independently of the actuating element against the elastic pretensioning of the first spring element, wherein the blocking element can be deflected in a relatively flexible manner due to the soft elastic pretensioning of the first spring element. This makes it possible to insert the closure part with magnetic assistance via the magnet arrangement, wherein due to the soft elastic pretensioning the seating of the closure part and the engagement with the closure element can be brought about in an automatic manner by magnetic attraction when the closure element is automatically deflected due to the magnetic attraction.

In one embodiment, the locking element can be formed in one piece. The locking element can have, for example, two first locking segments which are connected to the first plug-in segment when the closure device is in the closed position, and two second locking segments which are connected to the second plug-in segment in the closed position.

Alternatively, however, the blocking element can also be designed in multiple parts. The blocking element can thus be formed, for example, by two halves. It is conceivable here for each half to form a latching section for connection to one of the plug sections. However, it is also conceivable for each half to form, for example, two latching sections for connecting both the first and the second plug section.

If the blocking element is designed in multiple parts, each part of the blocking element can be operatively connected to the actuating element and can be moved by the actuating element.

In one embodiment, the first closing element and the second closing element can be inserted into each plug-in opening, for example.

Since the first closing part and the second closing part can be inserted into each plug-in opening, the first closing part and the second closing part can be designed as a common part. This makes it possible to simplify the production with variable availability and also simpler handling, and thus to reduce the production costs.

In one embodiment, the third magnet arrangement with the same magnetic pole points in each case at the first and second plug-in openings. The third magnet arrangement is shared in magnetically attractive fashion with the first magnet arrangement of the first closing part and with the second magnet arrangement of the second closing part, wherein the first and second magnet arrangements, when the first and second closing parts are mounted on the housing module, point towards the third magnet arrangement, for example with like-named poles, respectively. Since the third magnet arrangement with the same magnetic pole points toward the closure element, the structurally identical closure element with the same magnet arrangement can be inserted into the two plug-in openings to magnetically attract the third magnet arrangement of the housing module.

The third magnet arrangement can be directed with a single magnetic pole, for example with a north pole, towards each closure part, wherein in this 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 magnetically attractive with a north pole.

Alternatively, the third magnet arrangement can also provide a magnetic pole arrangement in which, for example, the north pole and the south pole (and optionally further magnetic poles) are arranged one above the other or next to one another. In this case, the first closing part and the second closing part are directed toward the third magnet arrangement with the same arrangement of magnetic poles, i.e. with the same arrangement of magnetic poles arranged one above the other or adjacent to one another, so that the closing parts interact in each case magnetically attractive manner with the housing modules.

However, it is also conceivable that the first closing part and the second closing part point with different magnetic poles at the third magnet arrangement and, for this purpose, cannot be inserted (at least magnetically) into the two plug-in openings, respectively, but rather interact magnetically attractive with the third magnet arrangement only when the first closing part and the second closing part are inserted into the plug-in openings associated with the respective closing part.

The third magnet arrangement can be formed by one or more permanent magnets. In this case, the first and second magnet arrangements of the first and second closure parts can likewise be formed by one or more permanent magnets or alternatively by magnetic armatures made of 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 is arranged between the first and second closure parts in the closed position, 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 located centrally between the plug-in openings, so that the closure part can be approached on both sides to the third magnet arrangement, so that the third magnet arrangement magnetically attracts 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 arrangement of the closure element, the mounting of the closure element on the housing module is magnetically assisted, so that the closure of the closure element can preferably be carried out as automatically as possible in order to establish a form-fitting connection of the closure element with the housing module.

In one embodiment, the third magnet arrangement is arranged on the operating assembly and is adjusted together with the operating assembly when the latter is operated. This can be achieved: the magnet arrangement can also be adjusted relative to the closure part and the magnet arrangement arranged thereon when the operating assembly is operated to release the closure part from the housing module, so that the magnetic attraction of the third magnet arrangement with the magnet arrangement of the closure part is also weakened when the operating assembly is operated, thereby facilitating the removal of the closure part from the housing module.

In this case, the third magnet arrangement can be arranged firmly on the operating assembly, for example on the operating element, and can thus be moved in a similar manner to the operating element when the latter is operated. However, the third magnet arrangement can also be operatively connected (only) to the operating element and, for example, be rotated about an axis when the operating element is operated, so that the magnetic poles of the magnet arrangement are reversed, for example, to magnetically repel one another from the magnetic attraction of the closure member.

When the third magnet arrangement is adjusted relative to the closure part, the magnetic attraction can possibly even be converted into magnetic repulsion due to the so-called edge effect. Thus, magnetic repulsion occurs when magnets magnetically attractably opposing in a closed position with different named poles move tangentially with their opposing pole faces relative to each other when open. If the magnets have at least approximately the same pole shape (i.e. the surfaces with which the poles oppose are shaped essentially identically), and the magnets are moved a certain distance, for example approximately their width (measured in the opening direction) or approximately less than their width relative to each other along the opening direction, and where the pole faces are held parallel to each other (so that the magnets are placed, for example, approximately edge to edge), magnetic repulsion between the magnets is thus created, which reaches a maximum with further displacement and then slowly falls.

The closure element can be guided on the housing module via suitable guide means, which facilitates the mounting of the closure element on the housing module and, furthermore, prevents the closure element from tilting relative to the housing module when the operating assembly is operated to release the closure element.

In one embodiment, the housing module has a housing on which the operating assembly is adjustably arranged. The actuating assembly can be adjusted in the actuating direction relative to the housing in order to release the first and second closure parts from the housing module, for example, in that: the user acts on the operating assembly and presses the operating assembly in the manner of a push button into the housing. By actuating the actuating assembly, the form-fitting connection between the housing module and the closure element is eliminated, so that the closure element can be removed from the housing module and the closure device opened.

In one embodiment, the actuating element is elastically pretensioned against the actuating direction toward the housing. The operation of the operating assembly is thus carried out against the spring force provided by the elastic pretension, for example by means of one or more spring elements. After the completion of the operation, the operating assembly returns, due to the elastic pretensioning, into an initial position in which, upon reinsertion of the closure element onto the housing module, a locking of the closure element with the housing module can be achieved, and the closure device can be closed again.

In one embodiment, the spring force provided by the spring pretension exceeds a predetermined minimum force in this case. The idea behind this is: the closure device can be opened only by a specific user, for example an adult, when used as a buckle on a baby carriage or a child seat, for example, while a child should not be able to easily open the closure device. The operation of the operating assembly should therefore require a minimum force that cannot be easily applied by a child. The minimum force can be set by dimensioning the one or more spring elements which provide the elastic pretension of the operating assembly. For example, the minimum force can be greater than or equal to 5 newtons, preferably greater than or equal to 10 newtons, more preferably greater than or equal to 20 newtons, or even greater than or equal to 50 newtons.

In one embodiment, the first closing part with the first plug section and the second closing part with the second plug section can each be inserted into one of the plug openings in the closing direction for connection to the housing module. The closing direction, along which the closing part can be inserted onto the plug-in opening, is oriented here, for example, transversely to the operating direction, wherein the closing directions can lie in a common plane or even be collinear, but are oriented opposite one another. For example, the plug-in openings on the housing modules are formed on opposite sides of the housing modules such that the closure part can be plugged onto the housing modules by means of the plug-in sections thereof on sides facing away from each other in order to be lockable with the housing modules, wherein the closure part is arranged with the magnet arrangement of the closure part magnetically attracted to the magnet arrangement of the housing modules.

In one embodiment, the first plug section and the second plug section each have a latching head for establishing a form-fitting connection with the housing module. The latching head can have at least one impact ramp extending obliquely to the closing direction and obliquely to the operating direction, which can be designed to impact the latching head against the associated latching section on the housing module when the respective plug-in section is inserted, so that a form-fitting connection between the plug-in section and the housing module is established.

In one embodiment, the locking head has two impact ramps formed on the sides of the locking head facing away from each other. The impact ramps are preferably oriented in a mirror-inverted manner in the respective closing direction, so that the locking heads have a wedge shape with the impact ramps on the sides facing away from one another.

The locking head is embodied mirror-symmetrically with respect to a mirror-symmetry plane oriented perpendicularly to the operating direction, for example. In general, each closing element can be designed substantially mirror-symmetrically with respect to a mirror-symmetry plane oriented perpendicularly to the operating direction.

According to a further aspect, in a general embodiment, the closure device comprises: a first closure part having a first plug-in section and a first magnet arrangement; a second closure part having a second plug-in section and a second magnet arrangement; and a housing module having two plug-in openings, a third magnet arrangement and an operating assembly. For connection to the housing module, the first closing part can be inserted in each case into one of the plug-in openings by means of the first plug-in section with the first magnet arrangement magnetically attracted to the third magnet arrangement and the second closing part can be inserted in each case with the second magnet arrangement magnetically attracted to the third magnet arrangement by means of the second plug-in section and connected to the housing module in a form-fitting manner in the closing direction. The operating assembly is operable to release the first and second closure members from the housing module. It is proposed that the first and second closing parts can be inserted into each plug-in opening.

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

In one embodiment, the actuating assembly has a locking element forming a locking section which, in the closed position, is connected in a form-fitting manner to the first plug section of the first closure part and to the second plug section of the second closure part.

The locking element can be adjusted by actuating the actuating assembly, so that the locking section can thus be disengaged from the first and second plug-in sections.

The actuating assembly can have, for example, an actuating element, for example in the form of a pressing element, which can be acted upon by a user in order to be able to actuate the actuating assembly. When the operating element is actuated, the blocking element is adjusted together with the operating element and is thus effectively connected to the operating element.

In one embodiment, the locking element is elastically pretensioned with respect to the housing section of the housing module via a first spring element. In contrast, the actuating element is elastically pretensioned with respect to the housing section of the housing module via a second spring element, wherein the first spring element and the second spring element have different spring constants. The first spring element and the second spring element can be designed, for example, as compression springs, so that when the operating element is operated in the operating direction, the first spring element and the second spring element are tensioned under pressure.

In one embodiment, the actuating assembly has an actuating element on which an impact ramp is formed, which, during actuation of the actuating assembly, acts in a force-deflecting manner on the first and second plug-in sections in order to be able to assist the release of the first and second plug-in sections. The reaction element can, for example, be firmly connected to an operating element of the operating assembly and can be moved in an operating direction when the operating assembly is operated. In this case, for example, an operative connection with the blocking element can be established via the active element, so that when the actuating assembly is actuated in the actuating direction, the blocking element is moved together with the active element in the actuating direction. As a result of the fact that the impact ramp is formed on the actuating element, in the event of insertion of the insertion part onto the housing module, the actuating element acts on the plug-in section of the closure part such that it is conveyed out of the plug-in opening counter to the respectively associated closing direction, in such a way that, when the actuating assembly is actuated, the release of the closure device is assisted by: the closure element is pressed out of the plug-in opening counter to the respectively associated closing direction. The closure part can thus be removed from the housing module in a simple manner when the operating assembly is operated.

The impact ramp can be firmly connected to the active element or can be formed by an elastically deformable element which is gradually pretensioned during the actuation of the actuating element and presses the closure part out of the plug-in opening from a predetermined actuating point.

The object is also achieved by a closure device having: a first closure part having a first plug-in section and a first magnet arrangement; a second closure part having a second plug-in section and a second magnet arrangement; and a housing module having two plug-in openings, a third magnet arrangement and an operating assembly. For connection to the housing module, the first closing element can be inserted into one of the plug-in openings by means of the first plug-in section with the first magnet arrangement magnetically attracted to the third magnet arrangement and the second closing element can be inserted into one of the plug-in openings by means of the second plug-in section with the second magnet arrangement magnetically attracted to the third magnet arrangement and connected to the housing module in a form-fitting manner in the closing direction, wherein the actuating assembly is operable to release the first closing element and the second closing element from the housing module. It is proposed that the actuating assembly has an actuating element, on which an impact ramp is formed, which acts in a force-deflecting manner on the first and second plug-in sections during the actuation of the actuating assembly in order to be able to assist the release of the first and second plug-in sections.

The closure device can be combined with the above-described aspects and different embodiments, so that reference should be made to the above-described embodiments in this respect.

The reaction element can, for example, be firmly connected to an operating element of the operating assembly and can be moved in an operating direction when the operating assembly is operated. Via the active element, an operative connection can be established, for example, with the blocking element, so that, when the operating assembly is operated in the operating direction, the blocking element moves together with the active element in the operating direction. Due to the fact that the impact ramp is formed on the actuating element, when the closure part is inserted into the housing module, the actuating element acts on the plug-in section of the closure part such that said plug-in section is conveyed out of the plug-in opening counter to the respectively associated closing direction, in order to assist the release of the closure device when the actuating assembly is actuated, in that: the closure element is pressed out of the plug-in opening counter to the respective associated closing direction. The closure part can thus be removed from the housing module in a simple manner when the operating assembly is operated.

The impact ramp can also be firmly connected to the active element or be formed by an elastically deformable element which is gradually pretensioned during the actuation of the actuating element and presses the closure part out of the plug-in opening from a predetermined actuating point.

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

In addition, a band coupling element with a further band coupling device for fixing a further band can be provided (respectively) on the first and/or second closure part. Such a band coupling element can be provided, for example, on the body of the respectively associated closure part in such a way that: the body extends through the opening of the strap coupling element. This arrangement of the band coupling element on the associated closure part makes it possible to releasably hold the band coupling element on the closure part, wherein in the closed position of the closure device the band coupling element is firmly connected to the housing module via the closure part.

If a belt coupling element with a further belt coupling is provided on each of the two closure parts, five belts can be connected to one another via the closure means.

Closures of the type mentioned can be used, for example, on strollers or child seats for securing the straps to one another. Such closure devices can generally be used at any location where it is desired to secure components to one another, such as for securing straps, bands, belts, cords or other elements to one another.

Detailed Description

In the exemplary embodiment shown in fig. 1A, 1B to 7A-7C, the closure device 1 has a housing module 2 and two

closure parts

3, 4 to be mounted on the housing module 2. The

closure members

3, 4 can be mounted on the housing formed by the

housing parts

20, 21 of the housing module 2 along the closing directions X1, X2, respectively, and are locked with the housing module 2 in the closed position, so that the

closure members

3, 4 can be fixed relative to the housing module 2 counter to the closing directions X1, X2.

Referring first to the exploded views in fig. 1A and 1B, the housing part 20 of the housing module 2 forms plug-in

openings

200, 201 into which in each case one

closure part

3, 4 can be inserted by means of the plug-in

sections

31, 41 in the respectively associated closing direction X1, X2. The housing part 21 is placed on the housing part 20 and is firmly connected to the housing part 20, so that the plug-in

openings

200, 201 are delimited upward by the housing part 21.

A belt coupling 204 is formed on the housing part 20, via which the belt can be fixed on the housing module 2.

The housing module 2 has an actuating assembly 28, which is formed by the actuating element 22, the actuating element 23 connected to the actuating element 22 and the blocking element 24. The actuating assembly 28 is accommodated in an opening 210 in the housing part 21 and can be actuated in particular for releasing the

closure parts

3, 4 from the housing module 2.

The operating element 22 can be operated by a user in the operating direction B by: the user acts on the face section 220 of the actuating element 22 and presses the actuating element 22 in the actuating direction B into the housing formed by the

housing parts

20, 21. Operating element 22 is guided on housing part 21 via a guide element 221 in the form of a tab projecting laterally from face section 220 in operating direction B in such a way that: the webs 223 engage in associated recesses 211 on the side within the opening 210 of the housing part 21 and the actuating element 22 is therefore guided in a straight line in the actuating direction B toward the housing part 21.

In the embodiment shown, the reaction element 23 is firmly connected to the operating element 22 in such a way that: the locking head 233 is inserted into the locking groove 222 on the inner side of the guide element 221 and is locked on the end section of the locking groove 222.

On both sides of the body 230, the reaction element 23 has a coupling element 234 in the form of a wedge, via which the reaction element 23 is effectively connected with the blocking element 24 when the operating element 22 is operated, in such a way that: the coupling element 234 engages into an engagement section 243 on the pin 240 protruding from the body of the blocking element 24. When the actuating element 22 is actuated, the actuating element 23 therefore presses the blocking element 24 in the actuating direction B, so that the blocking element 24 moves together with the actuating element 22 and the actuating element 23.

Two latching

sections

241, 242, which are intended for a form-fitting connection with the

closure parts

3, 4 and which are also described below, are each formed on both sides on the latching element 24.

The actuating assembly 28 is elastically prestressed relative to the housing part 20 of the housing module 2 via the

spring elements

26, 27. The central spring element 26 in this case pretensions the assembly of the actuating element 22 and the reaction element 23 against the actuating direction B against the housing part 20 in that: the spring element 26 is supported on the housing part 20 at one end, passes through an opening 244 in the body of the locking element 24 and bears on the other end against the locking element 23. In contrast, the spring element 27 pretensions the locking element 24 against the housing part 20 in that: the spring element 27 is supported on the one hand on the housing part 20 and on the other hand in the pin 240 of the blocking element 24.

While the spring element 26 has a relatively large spring constant and thus pretensions the actuating element 22 against the housing part 20 with a relatively hard spring force, the spring element 27 can be designed to be relatively soft and to have a low spring constant and thus pretensions the blocking element 24 against the housing part 20 in a relatively soft manner.

Within the body 230 of the blocking element 23 a magnet arrangement 25 is enclosed, which magnet arrangement 25 is formed by two permanent magnets in the embodiment shown.

The

closure parts

3, 4 each have a

body

30, 40 on which the plug-in

sections

31, 41 are formed. Each plug-in

section

31, 41 has two latching

heads

310, 410 which form impact ramps 311, 312 on the sides facing away from one another (in the operating direction B) and serve to establish a form-fitting connection with the latching

sections

241, 242 of the latching element 24 in the plugged position of the

closure parts

3, 4.

Two

guide webs

313, 413 are formed on the side of the plug-in

sections

310, 410, respectively, which guide webs are intended to engage with associated

guide grooves

202, 203 in the plug-in

openings

200, 201 of the housing part 20 when the

closure parts

3, 4 are inserted, so that the

closure parts

3, 4 are guided linearly in the associated closing direction X1, X2, respectively, towards the housing part 20. The

guide webs

313, 413 engage in the

guide grooves

202, 203 by guidance and also prevent the

closure parts

3, 4 from tilting during the actuation of the actuating assembly 28 and during the release from the housing assembly 2.

Each closing

part

3, 4 has a

magnet arrangement

35, 45, which is enclosed in the plug-in

section

31, 41 and which in the exemplary embodiment shown is realized by a permanent magnet.

A

handle

33, 43 and a

belt coupling

32, 42 for operation by a user are formed on each

closure part

3, 4.

On each

closure part

3, 4 there is also provided a

strap coupling element

34, 44 which forms an

opening

341, 441 in the

body

340, 440 through which the

body

30, 40 of the

closure part

3, 4 extends. The fixing

element

300, 400 for engagement into the associated fixing

engagement

343, 443 in the

opening

341, 441 of the

belt coupling element

34, 44 is formed on the

body

30, 40 of the

closure part

3, 4.

The

body

30, 40 of the

closure part

3, 4 can here preferably be accommodated in the

opening

341, 441 of the associated

belt coupling element

34, 44 in a different position, respectively, i.e. in a position which is twisted by 180 ° with respect to one another (with respect to the closing direction X1, X2). The

bodies

30, 40 can thus be inserted mirror-inverted into the respective associated

openings

341, 441.

The

strap coupling elements

34, 44 form a

further strap coupling

342, 442 and are releasably connected to the

body

30, 40 of the

closure part

3, 4, so that the

strap coupling elements

34, 44 can be removed, but are still firmly connected to the housing module 2 via the

closure parts

3, 4 in the closed position of the closure device 1.

Fig. 2A-2C show the closure device 1 in the closed position. In the closed position, the

closure parts

3, 4 are connected with the housing module 2 such that the strap 5 is jointly fixed on the housing module 2 and thereby connected to each other at one point.

In the closed position, the latching heads 310, 410, as can be seen in particular from the sectional view according to fig. 2C, are connected in a form-fitting manner with the latching

sections

241, 242 of the latching element 24, so that they are locked with the housing module 2 via this latching

part

3, 4. Due to the elastic pretensioning of the

spring elements

26, 27, the actuating assembly 28 is located in the closed position in an upper position in the housing formed by the

housing parts

20, 21.

In this upper orientation, viewed in the operating direction B, the magnet arrangement 25 of the operating assembly 28 is at substantially the same level as the

magnet arrangements

35, 45 of the

closure parts

3, 4, as can be seen from the sectional view according to fig. 2B. As can be seen from fig. 2B, the magnet arrangement 35 is here directed to the outside with a magnetic pole of the same name (south pole S in this case), wherein the

magnet arrangements

35, 45 of the

closure parts

3, 4 are each directed to the magnet arrangement 35 with the same magnetic pole (north pole N in this case). The

magnet arrangements

35, 45 of the

closure parts

3, 4 are thus each magnetically attracted against the magnet arrangement 35 of the housing module 2.

In the exemplary embodiment shown, the

closure parts

3, 4 are designed as a common part. In particular, the

closure parts

3, 4 are identically shaped on their plug-in

sections

31, 41, wherein furthermore the

magnet arrangements

35, 45 each point with a pole of the same name to the housing module 2 (if the

closure parts

3, 4 are attached to the housing module 2). This can be achieved: the closing

part

3, 4 can be inserted into each plug-in

opening

200, 201, and each closing

part

3, 4 can therefore also be inserted into the respective other plug-in

opening

201, 200.

The formation of the

closure parts

3, 4 by means of common parts enables simple handling and also simple production, while reducing the tool costs and also simplifying the installation, wherein special care does not have to be taken to arrange the

closure parts

3, 4 in the correct orientation.

With regard to the plug-in

sections

31, 41, in particular the latching

tabs

310, 410, the

closure parts

3, 4 are also formed mirror-inverted relative to a mirror-symmetrical plane extending perpendicularly to the operating direction B, which makes it possible to mount the

closure parts

3, 4 on the housing module 2 in mirror-inverted fashion.

Referring now to the views according to fig. 3A-3C to 6A-6C, to open the closure device 1, the user presses the operating element 22 in order to be able to press the operating element 22 in the operating direction B into the housing formed by the

housing parts

20, 21, as can be seen in the transition from fig. 3A-3C to fig. 4A-4C. The actuating element 23 is therefore moved together with the actuating element 22 in the actuating direction B and acts on the blocking element 24, so that the blocking

sections

241, 242 of the blocking element 24 are disengaged from the latching heads 310, 410 of the

closure parts

3, 4 in the actuating direction B.

In this case, the magnet arrangement 25 arranged on the reaction element 23 is also adjusted in the operating direction B and is removed from the

magnet arrangements

35, 45 of the

closure parts

3, 4, so that the magnetic attraction between the

closure parts

3, 4 and the housing module 2 is weakened (and possibly reversed due to edge effects).

The blocking element 23 has, on the side facing the

closure parts

3, 4, impact ramps 231, 232 for: in cooperation with the impact ramps 311, 411 on the upper side of the latching heads 310, 410 of the

closure parts

3, 4, in order to be able to press the

closure parts

3, 4 out of the plug-in

openings

200, 201 counter to the respectively associated closing direction X1, X2 when the actuating assembly 28 is actuated, as can be seen in the transition from fig. 3A to 3C to fig. 4A to 4C. The

closure parts

3, 4 are thus mechanically pressed out of the

plug openings

200, 201 at least a certain distance when opened, so that the

closure parts

3, 4 as shown in fig. 5A to 5C can be removed from the housing module 2 in a simple manner.

After the completion of the operation, the operating unit 28 automatically returns to the initial position, in which the face section 220 is arranged substantially flush with the upper side of the housing part 21, as a result of the elastic pretensioning of the

spring elements

26, 27, and the latching element 24 again assumes an orientation in which the

closure parts

3, 4 can be locked with the housing module 2 when being reset, as can be seen in fig. 6A to 6C.

When the

closure parts

3, 4 are placed on the housing module 2, as can be seen in fig. 7A to 7C, the

plug sections

31, 41 with the latching heads 310, 410 formed thereon abut against the latching

sections

241, 242 of the latching element 24, wherein the impact ramps 312, 412 on the latching heads 310, 410 impact against the impact ramps on the

plug sections

241, 242, and the latching element 24 is thereby deflected in the operating direction B, so that the latching heads 310, 410 can be moved in the respectively associated closing direction X1, X2 past the latching

sections

241, 242 and form a form-fitting engagement with the latching

sections

241, 242, as can be seen from the views according to fig. 3A to 3C corresponding to the closed position.

When the closed position is established, the blocking element 24 can be adjusted independently of the actuating element 22 and the actuating element 23 in the event of a relative movement of the coupling element 234 with respect to the engagement section 243, so that the blocking element 24 can be deflected against the elastic pretensioning of the spring element 27, and the

closure elements

3, 4 are brought into a form-fitting connection with the blocking element 24 by means of their

plug sections

31, 41.

Since the spring element 27 is of comparatively soft design, the deflection of the blocking element 24 during the setting of the

closure parts

3, 4 can take place in a comparatively flexible manner with a comparatively low force, so that the magnetic attraction of the

magnet arrangement

25, 35, 45 automatically causes the deflection of the blocking element 24 during the setting of the

closure parts

3, 4.

Due to the design and orientation of the

magnet arrangements

25, 35, 45, the

closure elements

3, 4 can be inserted into each plug-in

opening

200, 201. As schematically shown in fig. 8, this is achieved in particular as follows: the

magnet arrangements

35, 45 on the plug-in

sections

31, 41 of the

closure parts

3, 4 face the magnet arrangement 25 on the active element 23 of the housing module 2 with the same magnetic pole (in this case the north pole N), so that with magnetic attraction between the

magnet arrangements

25, 35, 45, respectively, each

closure part

3, 4 can be placed on the magnet arrangement 25 from each side.

In other embodiments, the

magnet arrangements

25, 35, 45, as is shown schematically in fig. 9, also each have a plurality of magnet poles N, S which point toward the respective associated

other magnet arrangement

25, 35, 45. In the case of the magnet arrangement 25 of the housing module, the two magnet poles N, S can therefore be arranged one above the other, wherein in this case the

closure elements

3, 4 have

identical magnet arrangements

35, 45, wherein the (precisely inverted) magnet poles N, S are arranged one above the other. Each closing

part

3, 4 can again be inserted into each plug-in

opening

200, 201, respectively, with magnetic attraction to the magnet arrangement 25 of the housing module 2.

In the exemplary embodiment according to fig. 9, the poles N, S of the

respective magnet arrangement

25, 35, 45 are arranged one above the other, viewed in the operating direction B. In an alternative embodiment, as is shown schematically in fig. 10, the

magnet arrangements

25, 35, 45 also each have a plurality of magnet poles N, S which are directed toward the respectively associated

other magnet arrangement

25, 35, 45 and are arranged next to one another in a transverse direction oriented transversely to the operating direction B and transversely to the closing directions X1, X2. Each closing

part

3, 4 can again be inserted into each plug-in

opening

200, 201, respectively, with magnetic attraction to the magnet arrangement 25 of the body module 2.

Since the

closing parts

3, 4 are also embodied radially symmetrically with respect to a mirror-symmetrical plane oriented perpendicularly to the operating direction B, in particular on the

plug sections

31, 41, the

closing parts

3, 4 can be rotated by 180 ° in a plane spanned by the operating direction B and the closing directions X1, X2 and inserted into the

plug openings

200, 201 on different sides of the housing module 2. Via the locking heads 310, 410 and the impact ramps 311, 312, 411, 412 formed on both sides thereof, the

plug sections

31, 41 can interact with the impact ramps on the latching

sections

241, 242 and with the impact ramps 231, 232 on the actuating element 23, respectively.

In the exemplary embodiment shown in fig. 11, a locking device 29 is provided on the housing module 2, which locking device serves to lock the actuating element 22 of the actuating assembly 28 in a locked position relative to the housing of the housing module 2 formed by the one or

more housing parts

20, 21. This therefore prevents an accidental actuation of the actuating element 22 and also releases it in the so-called two-way (2-Wege-

) The approach provides child safety. Accordingly, two operating steps are required to operate the operating element 22, namely on the one hand by displacing the locking element 290 and on the other hand by pressing the operating element 22 to unlock the locking device 29.

In the exemplary embodiment according to fig. 11, the locking device 29 is arranged laterally on the end face of the housing module 2.

In contrast, in the exemplary embodiment according to fig. 12, the locking device 29 with the displaceable locking element 290 is arranged on the upper side of the housing module 2, on which the actuating element 22 is also accessible.

In the embodiment according to fig. 12, the operating element 22 is also divided into two operating

parts

224, 225. The

actuating elements

224, 225 can be actuated separately from one another in order to be able in this way to release the

closure elements

3, 4 from the housing module 2 independently of the

other closure element

4, 3, respectively. For this purpose, the respectively associated

actuating element

224, 225 is actuated, which in turn moves the blocking element, for example in the manner of a rocker, so that the respectively associated

closure element

3, 4 is unlocked and is released from the housing module 2.

In this embodiment, each operating

part

224, 225 can have, for example, a third magnet arrangement for magnetically interacting with the respectively associated

closure part

3, 4.

The idea on which the invention is based is not limited to the embodiments described above, but can be implemented in different ways.

A closure device of the type described can be used in particular as a closure in a baby carriage or a child seat, but can also be used if desired in other applications, for example in sports seats (rally seats) or in any application in which a plurality of components are to be connected to one another at one point.
