Definitions

  • the invention relates to a closure device according to the preamble of claim 1.
  • Such a locking device has a first locking part which comprises a housing and a locking piece arranged on the housing, a second locking part which comprises an at least partially resiliently designed spring locking element, and magnetic means which act between the locking piece of the first locking part and the second locking part and cause a magnetic attraction force between the locking piece of the first closure part and the second closure part.
  • first locking part is attached to the second locking part in a locking direction, the locking process being supported magnetically due to the magnetic attraction of the magnetic means between the locking piece of the first locking part and the second locking part.
  • the locking piece and the spring locking element are then in engagement with one another, so that the locking part is locked against the second locking part counter to the locking direction.
  • the locking piece and the spring locking element thus form in the Closing position creates a form fit against the closing direction, so that the locking piece is held on the spring locking element in a latching manner in the closed position.
  • the spring locking element is displaced relative to the locking piece in an opening direction directed essentially transversely to the closing direction, in order in this way to disengage the spring locking element and the locking piece.
  • the closing takes place in a magnetically assisted manner in that the attachment of the first closure part to the second closure part and the latching engagement of the locking piece with the spring locking element is supported magnetically.
  • the first locking part is attached to the second locking part in the locking direction, thereby producing a locking engagement between the locking piece and the spring locking element.
  • the spring locking element is moved approximately in a straight line by moving the second locking part or at least a part of the second locking part in the opening direction essentially transversely to the closing direction, so that in this way the locking piece disengages from the spring locking element and the first locking part disengages from the second locking part can be removed.
  • a locking device of this type can be used in a variety of ways to connect two components to one another, one of the components being connected to the first locking part and the other of the components being connected to the second locking part and the locking of the locking parts to one another to secure the components be coupled with each other.
  • Closing devices of this type provide a secure, resilient connection between two parts in their closed position and can be closed in a simple manner and opened again in a haptically pleasant manner.
  • the possible uses of such closure devices extend to devices of a general type for (releasably) connecting two components, such as closures of pockets, flaps or lids, connecting devices for belts or leashes or even completely different components.
  • the locking piece of the first locking part is in the locking device of WO 2009/092368 A2 from the housing of the first closure part to engage To be able to produce the locking piece of the first locking part with the spring locking element of the second locking part can be unsightly and cumbersome when the locking device is open.
  • the WO 2012/066146 A1 describes a locking device in which a movable locking piece is arranged on a first locking part, which locking piece can be brought into engagement with a spring locking element on a second locking part.
  • An electrical coil for electromagnetic coupling is arranged in a closed position on each of the closure parts.
  • the DE 10 2013 213 633 A1 describes a closure device in which closure parts have locking surfaces on thread-like connecting areas.
  • the closure parts can be designed for electrical contacting.
  • the object of the present invention is to provide a closure device in which the locking piece in an open position of the closure device does not, if possible, prevent the use of a component connected to the first closure part.
  • the locking piece is movably arranged on the housing of the first closure part such that in a retracted position it is at least partially enclosed in a receiving chamber of the housing and in an extended position protrudes from the housing in such a way that it engages with the Spring locking element can be brought.
  • the present invention is based on the idea of arranging the locking piece movably on the housing of the first closure part.
  • the locking piece In a retracted position, the locking piece is largely arranged in the housing and therefore does not protrude or at least not completely protrude from the housing.
  • the locking piece In an open position of the locking device, the locking piece is in the retracted position and is therefore not a hindrance or disruption when using a component connected to the first locking part.
  • the locking piece is transferred from its retracted position to the extended position and in this extended position protrudes from the housing in such a way that it is brought into engagement with the spring locking element and thus latches on to the locking of the first locking part with the second locking part Spring locking element can be attached.
  • At least one first electrical contact element is arranged on the locking piece and at least one second electrical contact element is arranged on the second closure part. Electrical contacting can thus be provided via the closure device by having a contact element of the locking piece on the one hand and a contact element of the second closure part electrically in the closed position on the other hand contact each other and thus a current can be transmitted between the closure parts.
  • the transfer of the locking piece from the retracted position to the extended position is preferably carried out automatically by the action of the magnetic means, which act in a magnetically attractive manner between the locking piece and the second closure part. If the first locking part is attached to the second locking part, the magnetic means generate a magnetic force of attraction between the locking piece on the first locking part and the second locking part and transfer the locking piece from its retracted position to the extended position, so that the locking piece is mechanically connected to the spring locking element latched and the locking device can be locked in this way.
  • the magnetic means can be formed, for example, by two (permanent) magnets, one of which is arranged on the locking piece and the other on the second closure part.
  • magnets on one of the locking piece and the second locking part
  • magnetic armature made of ferromagnetic material, for example iron
  • the magnetic means are advantageously dimensioned in such a way that when the first closure part is attached to the second closure part, the locking piece is held in the extended position in order to bring the locking piece into engagement with the spring locking element.
  • the background here is that when the locking piece is attached to the spring locking element, the locking piece pushes the spring locking element aside in an elastic manner in order to bring the locking piece with a latching section into engagement with a corresponding latching section on the spring locking element.
  • the force required to push the spring locking element aside should be less than the magnetic force of attraction of the magnetic means, so that the locking piece is held in its extended position when it is engaged and is not pushed into its retracted position due to the force required to establish the latching.
  • the preload can also be brought about by a mechanical spring which acts between the locking piece and the housing of the first locking part and returns the locking piece to its retracted position after the locking device has been opened.
  • An adjusting element can be provided on the second closure part, which is mounted on a housing of the second closure part so as to be displaceable along the opening direction.
  • the spring locking element is arranged on this adjusting element, so that the spring locking element can be moved relative to the locking piece of the first closure part by actuating the adjusting element.
  • the spring locking element In the closed position, the spring locking element is in engagement with the locking piece, so that the first locking part is held on the second locking part.
  • the adjusting element can then be actuated in such a way that the spring locking element is moved relative to the locking piece and is brought out of engagement with the locking piece.
  • This adjusting element can for example be designed in the manner of a slide and mounted on the housing of the second closure part, the adjusting element being adjustable in the direction of the opening direction relative to the housing and the spring locking element being moved relative to the housing by actuating the adjusting element.
  • the closure device is therefore not opened by moving the second closure part as a whole, but by actuating the adjusting element of the second closure part, due to which the engagement between the locking piece and the spring locking element is released and the first closure part can be removed from the second closure part.
  • the magnetic means advantageously act between the locking piece of the first locking part and the adjusting element of the second locking part, so that the magnetic means also exert a force on the adjusting element in such a way that the adjusting element due to the magnetic force of attraction between the locking piece and the adjusting element when attaching of the first closure part is adjusted to the second closure part in such a position in which the locking piece can be brought into engagement with the spring locking element.
  • the spring locking element advantageously extends in a circumferential direction around the closing direction and is designed, for example, as a strip that is bent around the closing direction and resilient at least in sections, on which a latching section is arranged for latching engagement with a corresponding latching section on the locking piece. In the closed position, the spring locking element engages around the locking piece in the circumferential direction, at least in sections, so that the locking piece is held on the spring locking element by this encircling.
  • the spring locking element is opened circumferentially in sections in the opening direction, so that the locking piece can be released from the grip with the spring locking element by a relative movement between the spring locking element and the locking piece.
  • the locking piece is thus attached to the spring locking element in the closing direction and hereby pushes the spring locking element aside in an elastic manner in the direction of widening transversely to the closing direction, so that the spring locking element engages Engages with the locking piece and engages around the locking piece in a locking engagement position along the circumferential direction.
  • the spring locking element is then moved in the opening direction relative to the locking piece, so that the locking piece disengages from the spring locking element by a relative movement transverse to the closing direction.
  • the at least one first electrical contact element and the at least one second electrical contact element are preferably in electrical contact with one another in the closed position of the closure device. In the closed position, the at least one first electrical contact element of the locking piece is thus on the associated, at least one second electrical contact element of the second Closure part, so that an electrical connection is created between the closure parts.
  • the locking piece can have one or more electrical contact elements.
  • two first contact elements can be arranged on the locking piece which, in the closed position, make electrical contact with two assigned second contact elements of the second closure part. In this way, differently polarized currents (+, -) can be transmitted between the closure parts.
  • the locking piece In the extended position, the locking piece is preferably in contact with a contact element of the housing of the first closure part.
  • an additional electrical contact to the first contact element
  • the locking piece In the retracted position the locking piece is not in contact with the contact element of the housing, so that the locking piece is de-energized in the retracted position.
  • a switch for example a reed switch, is provided, which switches the locking piece in the retracted position to be de-energized.
  • a contact element can also be arranged on the housing of the first closure part, which contact element makes contact with an associated contact element of the second closure part in the closed position. Electrical contact between the closure parts is thus also established independently of the locking piece between the housing of the first closure part and the second closure part. In this way, for example, differently polarized currents can be transmitted on the one hand via the locking piece and on the other hand via the additional contact on the housing.
  • a further contact element which does not make contact with the contact element of the second closure part can also be arranged on the housing of the first closure part in addition to a first contact element (which contacts an associated contact element of the second closure part in the closed position). Electrical contact is made between the first contact element and the further contact element arranged on the housing by a bridging contact element arranged on the locking piece, which only establishes an electrical connection in the extended position of the locking piece, the locking piece itself remaining de-energized. In this way, the first contact element arranged on the housing is de-energized when the locking piece is in the retracted position. Multipole arrangements can also be implemented by arranging any number of these connections.
  • a first exemplary embodiment of a closure device 1, shown in FIG Figures 1 to 6 has a first closure part 2 and a second closure part 3, which are present separately from one another in an open position, for closing in a Closing direction X can be attached to one another and are locked together in a closed position.
  • the first closure part 2 comprises a housing 21 with a housing section 210 which encloses a receiving chamber 213.
  • a locking piece 22 is arranged displaceably.
  • the second closure part 3 comprises a housing 31 to which a housing part 32 is attached.
  • a holding section 330 which holds a spring locking element 34 in a rotationally fixed manner on a receiving opening 310 of the housing 31, is arranged on the housing 31.
  • a section of a pocket cover can be held in a clamped manner between the housing 31 and the housing part 32.
  • the locking piece 22 arranged on the housing 21 of the first closure part 2 and the spring locking element 34 arranged on the housing 31 of the second closure part 3 serve to mechanically lock the first closure part 2 with the second closure part 3 in a closed position.
  • the locking piece 22 and the spring locking element 34 each have one or more latching sections 222 and 340, which can be brought into engagement with one another in a latching manner to lock the first locking part 2 with the second locking part 3 and, in the closed position, provide a positive connection of the locking piece 22 the spring locking element 34 cause.
  • the first closure part 2 can be attached to the second closure part 3 in a closing direction X in order to transfer the closure device 1 into its closed position, as will be shown below with reference to FIG Figures 3 to 6 still to be explained in detail.
  • the spring locking element 34 extends here along a circumferential direction U around the closing direction X and is circumferentially opened in sections through an opening 341.
  • the spring locking element 34 is displaced relative to the locking piece 22 in an opening direction Y, which is directed essentially transversely to the closing direction X, so that the locking piece 22 is guided through the circumferential opening 341 on the spring locking element 34 and out of engagement with the spring locking element 34 reached.
  • FIGS 3A and 3B show the locking device 1 before the locking device 1 is closed.
  • the locking piece 22 has retracted into the receiving chamber 213 of the housing 21 and is thus in a retracted state in which it does not protrude outward from the housing 21.
  • a magnet 212 is arranged, which faces a magnet 223 of the locking piece 22 in a magnetically attractive manner (see FIG Figure 3B ). Due to the magnetic force of attraction between the magnets 212, 223, the locking piece 22 in the open position of the locking device 1 is initially held in its retracted position.
  • the locking piece 22 In the extended position, the locking piece 22 extends through an opening 211 on the housing 21 and projects outwardly from the housing 21.
  • the locking piece 22 rests against the edge section of the opening 211 that delimits the receiving chamber 213 in the closing direction X, so that an end position for the extended position is defined by the border of the opening 211.
  • the magnets 223, 331 realize magnetic means for generating an attractive force between the locking piece 22 and the second closure part 3 and fulfill two functions.
  • the magnetic means 223, 331 have the effect that the locking piece 22 when the first closure part 2 is attached to the second Closing part 3 from its retracted position (see Figure 3B ) to its extended position (see Figure 4B ) is transferred.
  • the magnetic means 223, 331 generate a magnetic force of attraction that magnetically supports the closing of the locking device 1 and pulls the locking piece 22 into engagement with the spring locking element 34, so that the mechanical locking of the locking piece 22 with the spring locking element 34 with suitable dimensioning of the magnets 223, 331 can be produced in a largely automatic manner.
  • the magnetic means in the form of magnets 223, 331 are dimensioned so that when the locking piece 22 is attached to the spring locking element 34, the locking piece 22 is not returned to its retracted position, but the latching section 222 of the locking piece 22 engages with the latching section 340 of the spring locking element 34 reach and for this purpose the spring locking element 34 can push aside in the direction of widening.
  • Figures 5A and 5B show the locking device 1 in its closed position, in which the latching sections 222, 340 of the locking piece 22 and the spring locking element 34 are latching in engagement with one another, so that the engagement of the locking piece 22 with the spring locking element 34, the first locking part 2 in a mechanically locked manner on the second closure part 3 is held.
  • the locking piece 22 and the spring locking element 34 are displaced relative to one another along the opening direction Y, as shown in FIG Figures 6A and 6B is shown.
  • the second locking part 3 is moved together with the spring locking element 34 in the opening direction Y relative to the first locking part 2 with the locking piece 22 arranged thereon, so that the locking piece 22 passes through the circumferential opening 341 on the spring locking element 34 and disengages from the spring locking element 34 reached.
  • the magnets 223, 331 on the locking piece 22 and on the housing 31 are also removed from one another, so that the magnetic force of attraction between these magnets 223, 331 is weakened. If the first closure part 2 is sufficiently far away from the second closure part 3, the magnetic attraction force of the magnets 212, 223 acting between the housing 21 of the first closure part 2 and the locking piece 22 exceeds the magnetic attraction force of the magnets 223, 331, so that due to the magnetic attraction force between the magnets 212, 223 the locking piece 22 is pulled towards the magnet 212 on the housing section 210 of the housing 21 of the first closure part 2 and is thus transferred into its retracted position (see Figure 3B ).
  • the locking piece 22 In the retracted position, as mentioned, the locking piece 22 then does not protrude, or at least not interferingly, from the housing 21 to the outside, so that the locking piece 22 is not a hindrance when handling a component to which the first closure part 2 is connected and in addition, the overall aesthetic impression of this component (for example when used on a handbag or the like) is not impaired.
  • FIGS 7 to 12 show a further embodiment of a closure device 1, which essentially differs from the embodiment according to FIG Figures 1 to 6 differs in that two locking pieces 22a, 22b are provided on a housing 21 of a first closure part 2 and two spring locking elements 34a, 34b are provided on a housing 31 of a second closure part 3 and thus a double mechanical interlocking of the closure parts 2, 3 can be produced.
