Description

Technical Field

[0001] The present invention relates to a closure device. Background Art

[0002] This closure device includes a first closure component and a second closure component, wherein the first closure component has a first plug-in section and a first magnet device, and the second closure component has a second plug-in section and a second magnet device. The housing module includes two plug-in openings, a third magnet device and an operating component, wherein in order to connect to the housing module, the first closure component and the second closure component can be inserted into each plug-in opening by means of corresponding plug-in sections. This is carried out under the condition that the first magnet device and the third magnet device and the second magnet device and the third magnet device are magnetically attracted to each other, so that the magnetic assistance is used to place the closure component on the housing module. In the closed position, the closure component is connected to the housing module in a form-fitting manner and is thus retained on the housing module. The operating component can be operated to loosen the first closure component and the second closure component from the housing module so that the closure component can be removed from the housing module, thereby opening the closure device.

[0003] Such a closure device can be used, for example, as a belt buckle on a baby carriage or a child seat. A multi-belt connection can be provided via such a closure device, in that, for example, a plurality of belts can be connected to one another via a closure component and a housing module. Summary of the invention

[0004] The object of the present invention is to provide a closure device which is easy to handle, allows a safe and reliable connection in the closed position and can be produced simply and cost-effectively.

[0005] This object is achieved by the closure device according to the invention.

[0006] Therefore, the operating component includes a locking element having a locking section, which is connected in a closed position in a form-fitting manner to a first plug-in section of a first closure part and a second plug-in section of a second closure part, wherein the operating component has an operating element that can be operated by a user, wherein when the operating element of the operating component is operated, the locking element moves together with the operating element and can be adjusted relative to the operating element when the first closure part and the second closure part are inserted into each a plug-in opening.

[0007] The locking section of the locking element, for example in the form of an undercut, serves to lock the plug section relative to the housing module in the closed position, so that the plug section cannot be removed from the housing module in the opposite direction to the respectively associated closing direction, at least without actuating the operating assembly. In the closed position, the plug section is thus locked with the operating assembly, wherein by actuating the operating assembly the form-fitting connection is cancelled and the plug section can be removed from the housing module.

[0008] The locking element can be adjusted by actuating the actuating assembly, so that the locking section can be disengaged from the first plug section and the second plug section.

[0009] The operating element can be designed, for example, in the form of a push piece, on which a user can act in order to operate the operating assembly. When the operating element is operated, the locking element is adjusted together with the operating element and is thus effectively connected to the operating element. Due to the elastic prestressing of the operating assembly, the operating element and the locking element can be reset together in the opposite direction of the operating direction after the operation, so that the operating element and the locking element return to the initial position, in which the locking can be achieved by means of the closure part when inserted into the housing module. In this case, when the closure part is inserted into the plug opening of the housing module, the locking element can be adjusted independently of the operating element and can be moved relative to the operating element, so that the plug-in section of the closure part can, for example, touch the locking section of the locking element and can engage with the locking section in a form-fitting manner.

[0010] In this case, the operating element can also be in two parts and thus be formed by two operating parts to be operated by the user. By dividing the operating element into two operating parts, for example, a locking element can be operated (for example in the manner of a rocker) so that the closure parts can be released separately and independently of each other from the housing module. By operating the operating part of the operating element, the locking element can thus be operated to unlock the plug section of the associated closure part.

[0011] In one embodiment, the operating element can be locked via a locking device. In the locked 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 locking element.

[0012] In one embodiment, the locking element is elastically preloaded relative to the housing section of the housing module via a first spring element. In contrast, the operating element is elastically preloaded relative 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 configured, for example, as compression springs, so that when the operating element is operated in an operating direction, the first spring element and the second spring element are tensioned under pressure. The first spring element can be configured in this case 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 operating element is elastically preloaded relative to the housing section via the second spring element, and the second spring element can be configured to have a relatively large spring constant, so that the elastic preload of the operating element relative to the housing caused by the second spring element is greater than the elastic preload of the locking element relative to the housing caused by the first spring element.

[0013] In this way, the blocking element can be elastically prestressed in a relatively soft manner relative to the housing, while the actuating element is prestressed in a relatively hard manner relative to the housing via the second spring element.

[0014] When the operating element is operated to adjust the locking element to release the closure part, the operating element and the locking element move together so that the preload force of the spring element can be overcome together. The preload force (determined in particular by the hard spring constant of the second spring element) can be determined in this case so that the operating element can only be operated by overcoming a sufficient force to release the closure device, and the force is preferably determined so that, for example, a child cannot easily operate the operating element. In this way, the safety against accidental, unauthorized release of the closure device is increased.

[0015] When inserting the closure part, the locking element can be moved independently of the actuating element against the elastic preload of the first spring element, wherein the locking element can be deflected in a relatively flexible manner due to the soft elastic preload 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 preload, the placement of the closure part and the engagement with the locking element can be automatically initiated by magnetic attraction when the locking element is automatically deflected due to magnetic attraction.

[0016] In one embodiment, the locking element can be formed in one piece. The locking element can have, for example, two first locking sections, which are connected to the first plug section when the closure device is in the closed position, and two second locking sections, which are connected to the second plug section in the closed position.

[0017] Alternatively, however, the locking element can also be designed in multiple parts. Thus, the locking element can be formed, for example, by two halves. It is conceivable that each half forms a locking section for connection to one of the plug sections. However, it is also conceivable that each half forms, for example, two locking sections for connection both to the first plug section and to the second plug section.

[0018] If the locking element is designed in multiple parts, each part of the locking element can be operatively connected to the operating element and can therefore be moved by the operating element.

[0019] In one configuration, the first closure part and the second closure part can be inserted into each plug opening, for example.

[0020] Since the first closure part and the second closure part can be inserted into each plug opening, the first closure part and the second closure part can be configured as universal parts. This can simplify production under variable availability and simpler handling, thereby reducing production costs.

[0021] In one embodiment, a third magnet arrangement with poles of the same name points towards the first plug opening and the second plug opening, respectively. The third magnet arrangement here acts together with the first magnet arrangement of the first closure part and with the second magnet arrangement of the second closure part in a magnetically attractive manner, wherein the first magnet arrangement and the second magnet arrangement, for example, point towards the third magnet arrangement with poles of the same name when the first closure part and the second closure part are attached to the housing module. Since the third magnet arrangement with poles of the same name points towards the closure part, structurally identical closure parts with the same magnet arrangement can be inserted into both plug openings in order to be magnetically attracted to the third magnet arrangement of the housing module.

[0022] The third magnet arrangement can here point with a single magnetic pole, for example with a north pole, toward 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 toward the third magnet arrangement and thus interact magnetically with the north pole.

[0023] Alternatively, the third magnet arrangement can also provide a magnetic pole arrangement, wherein for example the north pole and the south pole (and optionally further magnetic poles) are arranged one above the other or adjacent to one another. In this case, the first closure part and the second closure part point to the third magnet arrangement with the same magnetic pole arrangement, i.e. have the same arrangement of magnetic poles arranged one above the other or adjacent to one another, so that the closure parts each interact with the housing module magnetically by attraction.

[0024] However, it is also conceivable that the first closure part and the second closure part point with differently named magnetic poles to the third magnet device and in this respect cannot be inserted into two plug-in openings respectively (at least magnetically), but only interact with the third magnet device by magnetic attraction when the first closure part and the second closure part are inserted into the plug-in opening associated with the corresponding closure part.

[0025] 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 also be formed by one or more permanent magnets, or alternatively by a magnetic armature made of ferromagnetic material.

[0026] 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.

[0027] In one design, the third magnet arrangement is arranged between the first closure part and the second closure part in the closed position, so 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. Therefore, the third magnet arrangement is located in a central position between the plug-in openings, so that the closure part can approach the third magnet arrangement on both sides so that the third magnet arrangement is magnetically attracted to 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 part, the placement of the closure part on the housing module is magnetically assisted, so that the closing of the closure device can preferably be carried out as automatically as possible to establish a shape-fitting connection between the closure part and the housing module.

[0028] In one design, the third magnet device is arranged on the operating assembly, and is adjusted together with the operating assembly when the operating assembly is operated. This can achieve that when the operating assembly is operated to release the closure component from the housing module, the magnet device can also be adjusted relative to the closure component and the magnet device arranged thereon, so that when the operating assembly is operated, the magnetic attraction between the third magnet device and the magnet device of the closure component is also weakened, thereby facilitating the removal of the closure component from the housing module.

[0029] In this case, the third magnet arrangement can be firmly arranged on the operating component, for example, on the operating element, and can thus move similarly to the operating element when the operating element is operated. However, the third magnet arrangement can also be (only) operatively connected to the operating element and, for example, rotated about an axis when the operating element is operated, so that the magnetic poles of the magnet arrangement are reversed, and thus, for example, the magnetic attraction with the closure part is reversed to magnetic repulsion.

[0030] When the third magnet arrangement is adjusted relative to the closure part, the magnetic attraction can even be converted into magnetic repulsion if necessary due to the so-called edge effect. Thus, when magnets that are magnetically attracted to each other in the closed position with poles of different names move tangentially relative to each other with their opposing pole faces during opening, magnetic repulsion occurs. If the magnets have at least approximately the same pole shape (i.e., the surfaces with which the poles are opposite are essentially shaped 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 in the opening direction, and the pole faces are held parallel to each other (so that the magnets are, for example, placed approximately edge to edge), a magnetic repulsion between the magnets thus occurs, which reaches a maximum with further displacement and then slowly decreases.

[0031] The closure element can be guided on the housing module via suitable guides, which facilitates the placement of the closure element on the housing module and also prevents the closure element from tilting relative to the housing module when the operating assembly is actuated to release the closure element.

[0032] In one embodiment, the housing module has a housing, and the operating assembly is adjustably arranged on the housing. The operating assembly can be adjusted relative to the housing in an operating direction to release the first closure part and the second closure part from the housing module, for example, by a user acting on the operating assembly and pressing the operating assembly in the form of a button into the housing. By operating the operating assembly, the form-fitting connection between the housing module and the closure part is cancelled, so that the closure part can be removed from the housing module and the closure device is opened.

[0033] In one embodiment, the operating assembly is elastically preloaded in the direction opposite to the operating direction toward the housing. The operating assembly is thus operated against a spring force provided by the elastic preload, for example, caused by one or more spring elements. After the operation is completed, the operating assembly returns to the initial position due to the elastic preload, in which the closing element can be locked to the housing module when the closing element is inserted onto the housing module again, and the closing device can be closed again.

[0034] In one embodiment, the elastic force provided by the elastic preload exceeds a predetermined minimum force. The idea behind this is that the closure device, for example when used as a buckle on a baby carriage or a child seat, can only be opened by a specific user, for example an adult, and that a child should not be able to open the closure device easily. The operation of the operating assembly should therefore require a minimum force that cannot be easily applied by a child. This minimum force can be set by dimensioning the spring element or elements that provide the elastic preload 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.

[0035] In one embodiment, a first closure component with a first plug section and a second closure component with a second plug section can each be inserted into one of the plug openings along a closing direction for connection to the housing module. The closing direction is oriented, for example, transversely to the operating direction, wherein the closing directions can lie in a common plane or even be colinear, but oriented in opposite directions to one another, along which the closure component can be plugged into the plug opening. For example, the plug openings on the housing module are formed on opposite sides of the housing module so that the closure component can be plugged into the housing module with its plug sections on sides facing away from one another in order to be able to lock with the housing module, wherein the closure component is arranged with a magnetic attraction between the magnet arrangement of the closure component and the magnet arrangement of the housing module.

[0036] In one design, 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 collision bevel extending obliquely to the closing direction and obliquely to the operating direction, and the collision bevel can be configured to cause the latching head to collide with the associated locking section on the housing module when the corresponding plug section is inserted, thereby establishing a form-fitting connection between the plug section and the housing module.

[0037] In one design, the latch head has two impact bevels formed on the sides of the latch head facing away from each other. The impact bevels are preferably oriented toward the corresponding closing direction in a mirror-inverted manner, so that the latch head has a wedge shape with impact bevels on the sides facing away from each other.

[0038] The latching head is, for example, designed mirror-symmetrically with respect to a mirror-symmetrical plane oriented perpendicularly to the actuation direction. Typically, each closure element can be designed substantially mirror-symmetrically with respect to a mirror-symmetrical plane oriented perpendicularly to the actuation direction.

[0039] According to another aspect, in a common design, the closure device comprises: a first closure component, the first closure component having a first plug-in section and a first magnet device; a second closure component, the second closure component having a second plug-in section and a second magnet device; and a housing module, the housing module having two plug-in openings, a third magnet device and an operating assembly. In order to connect to the housing module, the first closure component can be inserted into one of the plug-in openings by means of the first plug-in section when the first magnet device and the third magnet device are magnetically attracted, and the second closure component can be inserted into one of the plug-in openings by means of the second plug-in section when the second magnet device and the third magnet device are magnetically attracted, and connected to the housing module in a form-fitting manner along the closing direction. The operating assembly can be operated to release the first closure component and the second closure component from the housing module. It is proposed that the first closure component and the second closure component can be inserted into each plug-in opening.

[0040] The above-described aspects can be freely combined with a closure device of this type, so that in this respect reference should be made to the above-described embodiments.

[0041] In one embodiment, the operating assembly has a locking element which forms a locking section which, in the closed position, is connected in a form-fitting manner to a first plug-in section of the first closure part and to a second plug-in section of the second closure part.

[0042] By operating the operating assembly, the locking element can be adjusted so that the locking section can be disengaged from the first plug section and the second plug section.

[0043] The operating assembly can have, for example, an operating element, for example in the form of a push piece, on which a user can act in order to operate the operating assembly. When the operating element is operated, the locking element is adjusted together with the operating element and is thus operatively connected to the operating element.

[0044] In one embodiment, the locking element is elastically preloaded relative to the housing section of the housing module via a first spring element. In contrast, the operating element is elastically preloaded relative 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 both be designed, for example, as compression springs, so that when the operating element is actuated in the actuation direction, the first spring element and the second spring element are tensioned under pressure.

[0045] In one design, the operating assembly has an acting element on which a collision slope is formed, and when the operating assembly is operated, the collision slope acts on the first plug section and the second plug section in a force-deflecting manner so as to assist in releasing the first plug section and the second plug section. The acting element can, for example, be firmly connected to the operating element of the operating assembly and move in the operating direction when the operating assembly is operated. Via the acting element, for example, an effective connection with a locking element can be established here, so that when the operating assembly is operated in the operating direction, the locking element moves together with the acting element in the operating direction. Since the collision slope is formed on the acting element, when the insertion component is inserted into the housing module, the acting element acts on the plug section of the closure component so that it is conveyed out of the plug opening in the opposite direction to the corresponding associated closing direction, so that when the operating assembly is operated, the closure device is assisted in releasing, in the manner of: the closure component is pressed outward from the plug opening in the opposite direction to the corresponding associated closing direction. Therefore, when the operating assembly is operated, the closure component can be removed from the housing module in a simple manner.

[0046] The impact bevel can be firmly connected to the active element or can be formed by an elastically deformable element which, during actuation of the actuating element, is gradually prestressed and presses the closure part out of the plug opening starting from a predetermined actuation point.

[0047] The object is also achieved by a closure device, which has a first closure part, which has a first plug section and a first magnet device; a second closure part, which has a second plug section and a second magnet device; and a housing module, which has two plug openings, a third magnet device and an operating assembly. In order to be connected to the housing module, the first closure part can be inserted into one of the plug openings by means of the first plug section when the first magnet device and the third magnet device are magnetically attracted, and the second closure part can be inserted into one of the plug openings by means of the second plug section when the second magnet device and the third magnet device are magnetically attracted, and connected to the housing module in a positive fit in the closing direction, wherein the operating assembly can be operated to release the first closure part and the second closure part from the housing module. It is proposed that the operating assembly has an action element, on which a collision bevel is formed, which acts on the first plug section and the second plug section in a force-deflecting manner when the operating assembly is operated, so as to assist in releasing the first plug section and the second plug section.

[0048] The closure device can be combined with the above aspects and different embodiments, so that in this respect reference is made to the above embodiments.

[0049] The active element can be, for example, firmly connected to the operating element of the operating assembly and can move in the operating direction when the operating assembly is operated. For example, an effective connection with the locking element can be established via the active element, so that when the operating assembly is operated in the operating direction, the locking element moves together with the active element in the operating direction. Since a collision slope is formed on the active element, when the closing component is inserted into the housing module, the active element acts on the plug-in section of the closing component, so that the plug-in section is conveyed out of the plug-in opening in the opposite direction to the corresponding associated closing direction, so that the closing device is assisted in releasing when the operating assembly is operated, in that the closing component is pressed outward from the plug-in opening in the opposite direction to the corresponding associated closing direction. Therefore, when the operating assembly is operated, the closing component can be removed from the housing module in a simple manner.

[0050] The impact bevel can also be firmly connected to the active element or be formed by an elastically deformable element which, during actuation of the actuating element, is gradually prestressed and presses the closure part out of the plug opening starting from a predetermined actuation point.

[0051] In one embodiment, a strap connection device for fixing the strap is arranged on the first closure part and the second closure part. A strap connection device can also be arranged on the housing module, so that three straps can be connected to each other via the first closure part, the second closure part and the housing module.

[0052] In addition, a belt coupling element with a further belt coupling device for fixing a further belt can be arranged on the first closure part and / or the second closure part (respectively). Such a belt coupling element can be arranged, for example, on the body of the respectively associated closure part in such a way that the body passes through the opening of the belt coupling element. Such an arrangement of the belt coupling element on the associated closure part makes it possible to releasably hold the belt coupling element on the closure part, wherein in the closed position of the closure device, the belt coupling element is firmly connected to the housing module via the closure part.

[0053] If a strap coupling element with a further strap coupling device is provided on each of the two closure parts, five straps can be connected to one another via the closure device.

[0054] Closures of the type described can be used, for example, to secure belts to one another on a stroller or child seat. Such closures can generally be used in any location where multiple components need to be secured to one another, for example, to secure multiple belts, straps, belts, cords or other elements to one another.

[0081] exist Figure 1A , 1B In the embodiment shown in FIGS. 7A to 7C , the closure device 1 has a housing module 2 and two closure parts 3, 4 to be placed on the housing module 2. The closure parts 3, 4 can be placed on the housing formed by the housing parts 20, 21 of the housing module 2 along the closing direction X1, X2, respectively, and locked with the housing module 2 in the closed position, so that the closure parts 3, 4 can be fixed relative to the housing module 2 opposite to the closing direction X1, X2.

[0082] First refer to Figure 1A and 1B 2, the housing part 20 of the housing module 2 forms plug openings 200, 201, into which a closure part 3, 4 can be inserted by means of a plug section 31, 41 along 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 openings 200, 201 are delimited upwards by the housing part 21.

[0083] A strap connection 204 is integrally formed on the housing part 20 , via which the strap can be fastened to the housing module 2 .

[0084] The housing module 2 has an operating assembly 28, which is formed by an operating element 22, an active element 23 connected to the operating element 22, and a locking element 24. The operating assembly 28 is received in an opening 210 in the housing part 21 and can be operated in particular to release the closure parts 3, 4 from the housing module 2.

[0085] The operating element 22 can be operated by a user along the operating direction B in that the user acts on the face section 220 of the operating element 22 and thereby presses the operating element 22 into the housing formed by the housing parts 20, 21 along the operating direction B. The operating element 22 is guided on the housing part 21 via a guide element 221 in the form of a tab protruding laterally from the face section 220 along the operating direction B in that the web 223 engages in an associated recess 211 on the side in the opening 210 of the housing part 21 and the operating element 22 is thus guided in a straight line along the operating direction B toward the housing part 21.

[0086] In the exemplary embodiment shown, the active element 23 is firmly connected to the actuating element 22 in that the latching head 233 is introduced into the latching groove 222 on the inner side of the guide element 221 and latches at an end section of the latching groove 222 .

[0087] On both sides of the body 230, the active element 23 has coupling elements 234 in the form of wedges, via which the active element 23 is operatively connected to the locking element 24 when the operating element 22 is operated, in that the coupling elements 234 engage in an engagement section 243 on a pin 240 protruding from the body of the locking element 24. When the operating element 22 is operated, the active element 23 thus presses the locking element 24 in the operating direction B, so that the locking element 24 moves together with the operating element 22 and the active element 23.

[0088] Two locking sections 241 , 242 are respectively formed on both sides of the locking element 24 , which serve for a positive connection with the closure parts 3 , 4 , as will be described below.

[0089] The operating assembly 28 is elastically preloaded relative to the housing part 20 of the housing module 2 via the spring elements 26, 27. The central spring element 26 preloads the assembly of the operating element 22 and the active element 23 against the housing part 20 in the opposite direction of the actuation direction B, in that the spring element 26 is supported on the housing part 20 at one end, penetrates the opening 244 in the body of the locking element 24, and abuts against the locking element 23 at the other end. In contrast, the spring element 27 preloads the locking element 24 relative to the housing part 20 in that the spring element 27 is supported on the housing part 20 on the one hand and on the other hand in the pin 240 of the locking element 24.

[0090] The spring element 26 has a relatively large spring constant and thus preloads the operating element 22 with a relatively hard spring force against the housing part 20 , while the spring element 27 can be designed to be relatively soft and have a low spring constant and thus preloads the locking element 24 relatively softly against the housing part 20 .

[0091] Enclosed within the body 230 of the locking element 23 is a magnet arrangement 25 which is formed by two permanent magnets in the exemplary embodiment shown.

[0092] The closure parts 3, 4 each have a body 30, 40 on which a plug-in section 31, 41 is formed. Each plug-in section 31, 41 has two latching heads 310, 410, which form collision bevels 311, 312 on sides facing away from each other (along the actuation direction B) and are used to establish a positive connection with the locking sections 241, 242 of the locking element 24 in the plugged position of the closure parts 3, 4.

[0093] Two guide webs 313, 413 are respectively formed on the side of the plug-in sections 310, 410, which are used to engage with the associated guide grooves 202, 203 in the plug-in openings 200, 201 of the housing component 20 when the closure components 3, 4 are inserted, so that the closure components 3, 4 are linearly guided along the respectively associated closing directions X1, X2 toward the housing component 20. The guide webs 313, 413 also prevent the closure components 3, 4 from tilting when the operating component 28 is operated and released from the housing component 2 by guiding and engaging in the guide grooves 202, 203.

[0094] Each closure part 3 , 4 has a magnet arrangement 35 , 45 which is enclosed in the plug section 31 , 41 and which is realized in each case by a permanent magnet in the exemplary embodiment shown.

[0095] A handle 33 , 43 and a belt coupling device 32 , 42 for operation by a user are formed on each closure part 3 , 4 .

[0096] A belt coupling element 34, 44 is also provided on each closure part 3, 4, which forms an opening 341, 441 on the body 340, 440, through which the body 30, 40 of the closure part 3, 4 passes. A fixing element 300, 400 is formed on the body 30, 40 of the closure part 3, 4 for engaging in an associated fixing engagement 343, 443 in the opening 341, 441 of the belt coupling element 34, 44.

[0097] The bodies 30, 40 of the closure parts 3, 4 can hereby preferably be accommodated in the openings 341, 441 of the associated belt coupling elements 34, 44 in different positions, i.e. in positions rotated 180° relative to each other (with respect to the closing direction X1, X2). The bodies 30, 40 can thus be inserted into the respectively associated openings 341, 441 in a mirror-inverted manner.

[0098] The belt coupling elements 34 , 44 form a further belt coupling device 342 , 442 and are detachably connected to the bodies 30 , 40 of the closure parts 3 , 4 , so that the belt 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 .

[0099] Figure 2A-2C The closure device 1 is shown in the closed position. In the closed position, the closure parts 3, 4 are connected to the housing module 2, so that the strip 5 is fixed together on the housing module 2 and thus connected to each other at one point.

[0100] In the closed position, the latching heads 310, 410, such as in particular according to Figure 2C As can be seen in the sectional view of FIG, the locking sections 241, 242 of the locking element 24 are connected in a form-fitting manner, so that the locking components 3, 4 are locked with the housing module 2 via these. Due to the elastic prestressing of the spring elements 26, 27, the operating assembly 28 is located in an upper position in the housing formed by the housing components 20, 21 in the closed position.

[0101] In this upper position - viewed in the operating direction B - the magnet arrangement 25 of the operating assembly 28 is substantially at the same height as the magnet arrangements 35, 45 of the closure parts 3, 4, as can be seen from the Figure 2B As can be seen from the cross-sectional view of Figure 2B As can be seen in the figure, the magnet arrangement 35 here points outward with the same magnetic pole (in this case the south pole S), wherein the magnet arrangements 35, 45 of the closure parts 3, 4 respectively point with the same magnetic pole (in this case the north pole N) towards the magnet arrangement 35. The magnet arrangements 35, 45 of the closure parts 3, 4 are therefore respectively opposite to the magnet arrangement 35 of the housing module 2 in a magnetically attractive manner.

[0102] In the exemplary embodiment shown, the closure parts 3 , 4 are designed as common parts. In particular, the closure parts 3 , 4 are formed identically at their plug sections 31 , 41 , wherein the magnet arrangements 35 , 45 are also oriented with the same magnetic poles toward the housing module 2 (if the closure parts 3 , 4 are attached to the housing module 2 ). This makes it possible for the closure parts 3 , 4 to be inserted into each plug opening 200 , 201 and for each closure part 3 , 4 to be inserted into the respective other plug opening 201 , 200 .

[0103] The formation of the closure elements 3 , 4 by means of common parts allows for simple handling and also simple production, while reducing tool costs and also simplifies assembly, wherein no particular attention has to be paid to arranging the closure elements 3 , 4 in the correct orientation.

[0104] With regard to the plug sections 31 , 41 , in particular the latching heads 310 , 410 , the closure parts 3 , 4 are also formed in a mirror-inverted manner relative to a mirror symmetry plane extending perpendicularly to the actuation direction B, which allows the closure parts 3 , 4 to be attached to the housing module 2 in a mirror-inverted manner.

[0105] Now refer to Figures 3A-3C 6A-6C, in order to open the closure device 1, the user presses the operating element 22 so that the operating element 22 can be pressed into the housing formed by the housing parts 20, 21 along the operating direction B, as shown in FIG. Figures 3A-3C arrive Figures 4A-4C Therefore, the active element 23 moves together with the operating element 22 in the operating direction B and acts on the locking element 24, so that the locking sections 241, 242 of the locking element 24 are disengaged from the locking heads 310, 410 of the closure parts 3, 4 in the operating direction B.

[0106] Here, the magnet arrangement 25 arranged on the active element 23 is also adjusted in the operating direction B and is thus 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 may be flipped due to edge effects).

[0107] The locking element 23 has a collision bevel 231, 232 on the side facing the closure parts 3, 4, which is used to cooperate with the collision bevel 311, 411 on the upper side of the latching head 310, 410 of the closure parts 3, 4, so that when the operating component 28 is operated, the closure parts 3, 4 can be pressed outward from the plug openings 200, 201 in the opposite direction to the respectively associated closing direction X1, X2, as in the case of Figures 3A-3C arrive Figures 4A-4CThe closure parts 3, 4 are therefore mechanically pressed outwards at least a certain distance from the plug openings 200, 201 when opening, so that they can be easily opened as in Figures 5A-5C The closure parts 3 , 4 shown in FIG. 1 are removed from the housing module 2 .

[0108] After the operation is completed, the operating assembly 28 automatically returns to the initial position due to the elastic preload of the spring elements 26, 27, in which the face section 220 is arranged essentially flush with the upper side of the housing part 21, and the locking element 24 again assumes the following position, in which the closure parts 3, 4 can be locked with the housing module 2 when they are reinstalled, as shown in FIG. Figures 6A-6C As can be seen in .

[0109] When the closure parts 3, 4 are mounted on the housing module 2, as in Figures 7A-7C As can be seen in the figure, the plug-in sections 31, 41 with the locking heads 310, 410 formed thereon are in contact with the locking sections 241, 242 of the locking element 24, wherein the collision bevels 312, 412 on the locking heads 310, 410 collide with the collision bevels on the plug-in sections 241, 242, thereby deflecting the locking element 24 along the operating direction B, so that the locking heads 310, 410 can move along the corresponding associated closing directions X1, X2 through the locking sections 241, 242 and form a shape-fitting engagement with the locking sections 241, 242, as shown in FIG. Figures 3A-3C of the view corresponding to the closed position.

[0110] When establishing the closed position, when the coupling element 234 moves relative to the coupling section 243, the locking element 24 can be adjusted independently of the operating element 22 and the action element 23, so that the locking element 24 can be deflected to overcome the elastic preload of the spring element 27, and then the closing elements 3 and 4 form a shape-fitting connection with the locking element 24 by means of their plug-in sections 31 and 41.

[0111] Since the spring element 27 is relatively soft, the deflection of the locking element 24 when the closure parts 3, 4 are attached can be carried out in a relatively flexible manner with less force, so that the magnetic attraction force of the magnet arrangement 25, 35, 45 automatically causes the deflection of the locking element 24 when the closure parts 3, 4 are attached.

[0112] 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, respectively. Figure 8As schematically shown in the figure, this is achieved in particular as follows: the magnet devices 35, 45 on the plug-in sections 31, 41 of the closure parts 3, 4 are oriented with the same magnetic pole (in this case the north pole N) towards the magnet device 25 on the active element 23 of the housing module 2, so that each closure part 3, 4 can be placed on the magnet device 25 from each side under the condition of magnetic attraction between the magnet devices 25, 35, 45.

[0113] In other embodiments, the magnet arrangement 25, 35, 45, as in Fig. 9 , also each having a plurality of magnetic poles N, S, which point to the correspondingly associated other magnetic arrangements 25, 35, 45. Thus, in the case of the magnetic arrangement 25 of the housing module, two magnetic poles N, S can be arranged one above the other, wherein in this case the closure parts 3, 4 have the same magnetic arrangement 35, 45, wherein (precisely reversed) magnetic poles N, S are arranged one above the other. Each closure part 3, 4 can again be inserted into each plug opening 200, 201 under magnetic attraction with the magnetic arrangement 25 of the housing module 2.

[0114] In accordance with Fig. 9 In the embodiment of the present invention, the magnetic poles N, S of the respective magnet devices 25, 35, 45 are arranged one above the other - viewed in the operating direction B. In an alternative design, as in this Fig.10 As schematically shown in FIG. 1 , the magnet devices 25, 35, 45 also have a plurality of magnetic poles N, S, which point to the correspondingly associated other magnet devices 25, 35, 45 and are arranged adjacent to each other along a transverse direction oriented transversely to the operating direction B and transversely to the closing directions X1, X2. Each closure component 3, 4 can be inserted into each plug opening 200, 201 again when magnetically attracted to the magnet device 25 of the body module 2.

[0115] Since the closure parts 3, 4 are also designed radially symmetrically, especially on the plug-in sections 31, 41, with respect to a mirror symmetry plane oriented perpendicularly to the actuation direction B, the closure parts 3, 4 can be rotated 180° in a plane spanned by the actuation direction B and the closing directions X1, X2 and inserted into the plug openings 200, 201 on different sides of the housing module 2. The plug-in sections 31, 41 can interact with the actuation bevels 231, 232 on the locking sections 241, 242 and with the actuation bevels 231, 232 on the active element 23 via the latching heads 310, 410 and the actuation bevels 311, 312, 411, 412 formed on both sides thereof.

[0116] exist Fig.11In the embodiment shown in FIG. 1 , a locking device 29 is provided on the housing module 2, which is used to lock the operating element 22 of the operating assembly 28 in the locked position relative to the housing formed by one or more housing parts 20, 21 of the housing module 2. This prevents accidental operation of the operating element 22 and also prevents so-called two-way release. 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.

[0117] In accordance with Fig.11 In the exemplary embodiment of FIG. 2 , the locking device 29 is arranged laterally on the end side of the housing module 2 .

[0118] On the contrary, according to Fig.12 In the exemplary embodiment of FIG. 2 , the locking device 29 having the movable locking element 290 is arranged on the upper side of the housing module 2 , on which the operating element 22 is also accessible.

[0119] In accordance with Fig.12 In the embodiment of the present invention, the operating element 22 is further divided into two operating parts 224, 225. The operating parts 224, 225 can be operated separately from each other so that the closing parts 3, 4 can be released from the housing module 2 in this way independently of the other closing parts 4, 3. For this purpose, the corresponding associated operating parts 224, 225 are operated, thereby moving the locking element, for example, in the manner of a rocker, so that the corresponding associated closing parts 3, 4 are unlocked and then released from the housing module 2.

[0120] In this exemplary embodiment, each actuating element 224 , 225 can have, for example, a third magnet arrangement in order to interact magnetically with the respectively associated closure element 3 , 4 .

[0121] The concept on which the invention is based is not limited to the exemplary embodiments described above, but can be implemented in different ways.

[0122] A closure device of the type described can be used in particular as a closure in baby carriages or child seats, but optionally also 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.
