  • An exemplary closure device has an actuating element which is adjustably arranged on the base body and which is operatively connected to the at least one closure element in such a way that by adjusting the actuating element relative to the base body, the at least one closure element can be rotated relative to the base body.

  • a design of the closure device can be particularly advantageous when used, for example, on a belt system, for example for a child seat in a vehicle, in order to create a multi-point fastening in this way.
  • a belt can be arranged on every second closure part, so that by fastening the second closure parts to the first closure part, several belts can be attached to the first closure part. This results in simple handling, in particular for closing the closure device.

  • the blocking element 32 serves to block the engagement of the locking sections 222, 302 in the closed position with one another, as will be explained below with reference to the further exemplary embodiments.
  • second closure parts 3 are to be attached to closure elements 22 of a first closure part 2, wherein in this embodiment each closure element 22 has two locking sections 222A, 223A, 222B, 223B on different sides and thus the second closure elements 3 can be attached to a closure element 22 from different sides.
  • Fig.5 In the closed position shown, two second locking parts 3 are held on each side of the first locking part 2, so that a multi-point fastening is again created.
  • a belt 4 is arranged on a belt fastening 21 on a base body 20 of the first closure part 2.
  • each second closure part 3 has a belt fastening 31 on a base element 30, via which a belt 4 is fixed to the respective second closure part 3, as shown schematically in Fig.5 is marked.
  • two locking sections 222A, 223A, 222B, 223B are arranged on each side of a closure element 22, diametrically opposed to a rotation axis D (about which the closure element 22 is rotatably mounted on the base body 20 of the first closure part 2), which can each be brought into positive engagement with two locking sections 302, 303 on associated second closure parts 3.
  • each second closure part 3 has a blocking element 32 which is received with a head section 320 in a receiving space 300 of the base element 30 of the respectively associated second closure part 3 and which projects with a blocking section 321 into the area of the locking sections 302, 303 on the base element 30 of the second closure part 3.
  • the receiving space 300 is closed to the outside by a cover element 301.
  • Fig. 7 and 8A, 8B, 8C show a second closure element 3 on an associated closure element 22, which is rotatably mounted about a rotation axis D on the base body 20 of the first closure part 2.
  • Two magnetic elements 230, 231 are arranged on the closure element 22, which, when the second closure part 3 is attached to the closure element 22, interact in a magnetically attractive manner with magnetic elements 330, 331 on the base element 30 of the second closure part 3 (
  • Fig. 8A to 8C show the magnetic elements 230, 231, 330, 331 in a cutaway manner; as can be seen from Fig.9 in conjunction with Fig.10
  • the magnetic elements 230, 231, 330, 331 are each cylindrically shaped and, when a second closure part 3 is attached to an associated closure element 22 with unlike poles, they are located opposite one another in such a way that a magnetic force of attraction exists between the second closure part 3 and the closure element 22).
  • the locking sections 302, 303 with locking projections 304 formed thereon come into contact with the locking sections 222A, 223A on the associated side of the closure element 22 and run with run-up slopes 305 onto run-up slope 225 on the locking sections 222A, 223A of the closure element 22, so that the locking sections 302, 303 are moved past the locking sections 222A, 223A of the closure element 22 with an offset transverse to the direction of rotation D (opposite an engagement direction E).
  • the blocking section 321 of the blocking element 32 on the second closure part 3 comes into contact with the locking section 222A of the closure element 22 in the attachment direction A and is adjusted by the locking section 222A relative to the base element 30, counter to a magnetic attraction force between the blocking element 32 and the base element 30 due to an interaction between a magnetic element 322 on the head section 320 of the blocking element 32 (formed, for example, by a magnetic armature made of ferromagnetic material) and the magnetic elements 330, 331 on the base element 30.
  • the blocking section 321 of the blocking element 32 comes to lie on a radially inner side of the blocking section 222A of the closure element 22 facing away from the blocking section 302, as can be seen from Fig. 8B can be seen.
  • the blocking section 321 thus ensures the engagement between the locking sections 222A, 302 and, via this, also the engagement between the locking sections 223A, 303 on the other side.
  • the second closure part 3 cannot be displaced against the engagement direction E to the adjustment element 22 and the positive connection between the locking sections 222A, 223A, 302, 303 can not be canceled.
  • the closure element 22 can be rotated about the axis of rotation D along an actuation direction B1 by approximately 180°, so that, as in Fig. 8C shown, the locking sections 222A, 223A, 302, 303 come out of engagement with one another and the positive connection between the second closure part 3 and the closure element 22 is thus canceled.
  • the magnetic elements 230, 231, 330, 331 are also rotated relative to one another such that the magnetic elements 230, 231, 330, 331 are now each in pairs with poles of the same name in opposite positions, so that the magnetic elements 230, 231, 330, 331 magnetically repel one another and the release of the second closure part 3 from the closure element 22 is thus magnetically supported.
  • a second closure part 3 can be attached to each side of the closure element 22.
  • the second closure parts 3 are of identical construction, and the positive connection is produced in the same way for each second closure part 3 and can also be released again in the same way.
  • the first closure part 2 has an actuating element 24 which is designed as a rack and can be moved along an actuating direction B to the base body 20 of the first closure part 2.
  • the actuating element 24 is accommodated in a guide recess 202 of the base body 20 and guided in the guide recess 202 along the actuating direction B.
  • Support elements 245 protrude into spring receptacles 203 on both sides of the guide recess 202 and act on spring elements 244 in the form of compression springs accommodated in the spring receptacles 203, via which the actuating element 24 is moved against the actuating direction B to the base body 20.
  • the actuating element 24 in the manner of a rack has two toothings 242 on opposite sides, each of which is in coupling engagement with one of the closure elements 22.
  • each closure element 22 has a coupling section 221 in the form of a circumferential toothing, via which the actuating element 24 meshes with the respective closure element 22, so that when the actuating element 24 is actuated in the actuating direction B, the closure elements 22 are rotated together along an actuating direction B1, B2 to the base body 20 of the first closure part 2.
  • the closure elements 22 are adjusted to the respectively assigned second closure parts 3, so that the positive connection between the closure elements 22 and the second closure parts 3 is canceled and the second closure parts 3 can thus be removed from the first closure part 2 to open the closure device 1.
  • second closure parts 3 can be attached to different sides of a closure element 22, magnetic elements 230, 231 in the form of permanent magnets on the closure element 22 can also interact equally with the closure parts 3 on the different sides. Connecting the second closure parts 3 to the closure element 22 on its opposite sides thus enables a simple design for providing a multi-point fastening while reducing the number of components of the closure device 1, while also being easy to handle, in particular for opening the closure device 1.
  • the arrangement according to Fig. 7 and 8A to 8C can also realize a closure device 1 as such with (exactly) one closure element 22 to which two second closure parts 3 can be attached.
  • closure devices 1 can be realized in which a plurality of second closure parts 3 are to be attached to a first closure part 2, in other embodiments of a closure device 1 only a first closure part 2 and a second closure part 3 can be connected to one another.
  • the closure device 1 has a first closure part 2 and a second closure part 3 to be attached thereto, which in their function for attaching the second closure part 3 to the first closure part 2 and for releasing the closure parts 2, 3 from each other is the same as in the embodiment according to Fig. 7 and 8A to 8C are identical, so that, in particular with regard to the functioning of the locking sections 222, 223, 302, 303 and the blocking element 32 of the second closure part 3, reference should be made in full to the preceding explanations.
  • the closure element 22 of the first closure part 2 is formed in one piece with a belt fastening 21.
  • the closure parts 2, 3 can be rotated towards each other for opening, as is the case in the transition from Fig. 11A, 11B towards Fig. 12A, 12B is shown.
  • a two-part closure device 1 with a first closure part 2 and a second closure part 3 is thus created.
  • the closure element 22 of the first closure part 2 is arranged rotatably on a base body 20, which also includes a belt fastening 21, and can be rotated about an axis of rotation D relative to the base body 20 when the base body 20 is stationary in order to open the closure direction 1, as is the case in the transition from Fig. 14A, 14B towards Fig. 15A, 15B is shown.
  • the belt fastenings 21, 31 of the first closure part 2 and the second closure part 3 can thus remain in position relative to one another.
  • the functioning of the closure device 1, in particular for establishing the positive connection when attaching and releasing is identical to that described above, in particular with reference to Fig. 7 and 8A to 8C
  • the functioning of the barrier sections 222, 223, 302, 303 and the Blocking element 32 of the second closure part 3 reference should therefore be made to the above statements.
  • a locking device of the type described can be used as a belt buckle on a child seat for use in a vehicle or as a belt buckle for a stroller.
  • embodiments in which several second locking parts are to be connected to a first locking part can be used as multi-point fastenings in multi-point belt systems.
  • Such a closure device can also create a connection between two individual closure parts.
  • a closure device can be used, for example, as a buckle on a helmet, for example a sports helmet, a ski helmet or a bicycle helmet.
  • Such a closure device can also be used to connect completely different components to one another, for example as a closure for a bag, for example a school bag, or to attach other parts to one another.
  • An actuating element for actuating a locking element of the first locking part or for jointly actuating several locking elements of the first locking part can, as described, be designed as a gear or rack.
  • other actuating elements are also conceivable, for example in the form of a chain, a rope, a push button, a crank rod or a link element, whereby a force deflection takes place to convert an actuating movement into a rotary movement of one or more locking elements.
