Definitions

  • the invention relates to a closure device for connecting two parts according to the preamble of claim 1.
  • Such a closure device has a first connection module and a second connection module, which can be arranged in a closing direction to one another and mechanically locked in a closed position.
  • magnetic means are provided which cause a magnetic attraction between the connection modules to assist the transfer of the connection modules to the closed position.
  • connection modules in a vertical closing direction are set together and lock it mechanically.
  • a magnet or on the one hand a magnet and on the other hand a magnetic armature are arranged both on the first connection module and on the second connection module, the production of the mechanical latching and thus the transfer of the closure device in the closed position is magnetically supported.
  • the closing of the closure device is largely automatic, when the connection modules are approached to each other. By displacing or rotating the first connection module relative to the second connection module, the mechanical locking can then be released again, wherein at the same time the magnetic means are sheared off from one another by lateral movement and thus removed from one another.
  • Locking devices of this type on the one hand in their closed position a safe and reliable connection of two parts with each other available and on the other hand can be closed in a simple manner and opened again in a haptic pleasant way.
  • the uses of such closure devices extend to devices of a general type for (releasably) connecting two parts, such as closures of bags, flaps or lids, connecting devices for straps or lines or other components and the like.
  • the magnetic means realized for example by magnets or a magnet and a magnetic armature, small in order to save on costs for magnets and also to keep the construction volume of the closure device low.
  • the magnetic means should cause a sufficient magnetic force to create an attractive force between the connection modules, which allows a largely automatic mechanical latching.
  • connection modules are attached to each other. If the fitting takes place exactly in the closing direction with exactly aligned magnetic means, a large magnetic attraction between the connection modules, so that the transfer to the closed position is supported in a desired manner by the action of the magnetic means. If the magnetic means are not aligned exactly with one another, then the magnetic attraction force causes the connection modules to be aligned with one another, ie the magnetic attraction pulls the connection modules toward one another while aligning the magnetic means and in the closed position, in which the magnetic means should be aligned largely congruent frontal to each other.
  • connection modules This alignment of the connection modules to each other when closing the closure device is desirable.
  • a complete, optimal alignment is practically but only when the magnetic attraction of the magnetic means has a predetermined strength and the magnetic means are sized accordingly large. If the magnetic means are dimensioned small, it may happen that the magnetic attraction force is insufficient to align the connection modules to each other and to automatically transfer to the closed position in case of inexact alignment of the connection modules to each other when closing the closure device. This is due to the fact that with inaccurate positioning of the connection modules to each other, the respective magnetic means (such as magnet and armature) are not exactly opposite, but laterally offset from each other, so that the acting magnetic attraction force is smaller than in exact alignment of the magnetic means to each other. If this reduced magnetic attraction force is insufficient to produce the mechanical locking, the connection modules remain in an intermediate position in which the closure device is not completely closed; an automatic transfer to the closed position does not take place.
  • a closure device in which a first connection module can be attached to a second connection module, wherein magnetic means are provided to magnetically assist in establishing a closure position.
  • a closure device in the form of a plug-in buckle in which a connecting module can be moved linearly relative to another connecting module in order to open the closure device from a closed position.
  • the present invention has for its object to provide a closure device for connecting two parts, which allows a safe, haptic pleasant closing under largely automatic, magnetically assisted transfer to the closed position and thereby manages with small-sized magnetic means.
  • an additional guide portion is provided on the second connection module, which leads the first connection module in the closed position.
  • the guide portion is aligned so that it is directed with at least one direction vector component opposite to the example, transverse to the closing direction facing opening direction.
  • the guide section may be directed obliquely to the opening direction and thereby describe an obtuse angle with the opening direction.
  • a direction vector component means a vector component of the direction vector of the guide section.
  • the direction vector of the guide section points in the direction in which the guide section guides the first connection module.
  • This directional vector is mathematically decomposable into direction vector components, one of which is opposite to the Opening direction is directed.
  • a second directional vector component perpendicular to the first directional vector component may point in the closing direction.
  • a blocking piece is arranged on the first connecting module and a spring locking element is arranged on the second connecting module, which jointly realize a mechanical locking device.
  • Both the locking piece and the spring locking element may have locking projections in the manner of locking elements, which engage in a form-fitting manner with one another for the purpose of producing the mechanical locking.
  • the guide section is arranged in the closing direction in front of the latching projection of the spring locking element in such a mechanical latching.
  • the first connection module when it is attached with an offset to the second connection module (that is to say not exactly aligned along the closing direction), is first aligned with the second connection module, before the latching is then established.
  • the at least one guide portion an orientation such that the magnetic means are optimally opposed to generate a maximum attractive force; only then the latching projections of the locking piece and the spring locking element engage. This ensures that the production of mechanical locking is best supported by the magnetic means and can be dispensed with an oversizing of the magnetic means.
  • the guide section thus enables the magnetic means to optimally-without lateral offset-be aligned with one another for the purpose of producing the mechanical locking and to magnetically attract one another for the best possible support of the latching process.
  • the guide section is arranged in the closing direction in front of the locking projection of the spring locking element on the second connecting module, the guide section does not hinder lateral displacement of the first connecting module in the opening direction for opening the closing device.
  • the spring locking element and the locking piece are displaced relative to each other, so that the spring locking element is moved along the opening direction out of the region of the at least one locking piece.
  • the opening direction can be aligned transversely to the closing direction, wherein the mechanical locking between locking piece and locking element is canceled by the fact that locking projections of the locking piece and the spring locking element laterally, d. H. tangentially, be disengaged.
  • the at least one guide section for guiding the first connection module into the closed position can be arranged, for example, on a spring locking element or a plug receptacle of the second connection module.
  • the spring locking element serves on the one hand for producing the mechanical locking and on the other hand also for guiding the first connecting module into the closed position.
  • these functions are separated:
  • the spring locking element is used for mechanical locking, while the guide portion on the connector receptacle of the second connection module leads the first connection module in the direction of the closed position.
  • the locking piece of the first connection module may be formed substantially rotationally symmetrical and a latching projection for mechanical locking having a latching projection of the spring locking element of the second connection module.
  • the spring locking element may be formed substantially annular, extend around a central axis extending parallel to the closing direction and be arranged on a connector receptacle of the second connection module.
  • the spring locking element is thereby opened in sections in the circumferential direction and realized in this way a recess which allows removal of the locking piece of the first connection module in the opening direction (transverse to the closing direction) from the spring locking element of the second connection module and thus releasing the closure device.
  • the substantially ring-shaped spring locking element can be arranged in a variant rotatably on the connector receptacle of the second connection module.
  • the recess of the spring locking element is in this case seen from the central axis of such that the spring locking element is open in the opening direction, so that the locking piece of the first connection module can be pushed in the opening direction of the spring locking element of the second connection module.
  • the spring locking element holds in this way the locking piece against the closing direction by positive mechanical locking in the connector receptacle of the second connection module, but not against the opening direction in which the spring locking element is open. Contrary to the opening direction, the connection modules are held together in particular by the magnetic attraction of the magnetic means, which must be overcome for opening.
  • the spring locking element can also be arranged rotatably on the connector receptacle of the second connection module.
  • the spring locking element is rotatable about the central axis for releasing the first connecting module from the second connecting module, wherein in a secured position, the spring locking element is rotated so that it is not open in the opening direction (as viewed from the central axis of the spring locking element) (ie the recess of the spring locking element is located in a direction other than the opening direction viewed from the center axis), so that the locking piece can not be removed in the opening direction from the spring locking element. The mechanical locking of spring locking element and locking piece is thus secured.
  • this is Federverriegelungselement for releasing the first connection module from the second connection module about the central axis is rotated so that the recess of the spring locking element seen from the central axis in the opening direction is arranged and the spring locking element is thus open in the opening direction, so that the first connection module with its locking piece in the Opening direction can be pushed out of the spring locking element of the second connection module.
  • a lever may be arranged on the spring locking element in this case, with which the spring locking element from the secured in the unlocked position and vice versa can be rotated.
  • Conceivable in this context is also to bias the spring locking element by using, for example, a mechanical spring in a position, so that without actuation of the lever, the spring locking element is always arranged for example in the secured position in which a release of the first connection module from the second connection module is not possible ,
  • the locking piece of the connection module can substantially into a Extend longitudinally at an angle to the closing direction and have a locking projection for mechanical locking with a locking projection of a spring locking element of the second connection module.
  • locking piece and spring locking element are not rotationally symmetrical, but extend in a longitudinal direction on the first connection module or on the second connection module. Both on the locking piece and on the spring locking element locking projections are formed, which together when attaching the first connection module to the second connection module engage and establish the mechanical locking.
  • the first connection module and the second connection module are displaced relative to each other along the opening direction, the opening direction being directed along the longitudinal direction of the locking piece.
  • the locking piece can be directed so that the opening direction is aligned with a direction vector component counter to a main load direction, so that under the action of a load in the main load direction no opening of the closure device can take place.
  • This latching means can also be realized by the spring locking element, which in the closed position, the locking piece circumferentially surrounds such that to release the connection modules from each other, a spring force of the spring locking element must be overcome. Due to the circumferential gripping the spring locking element counteracts opening of the closure device, wherein by dimensioning of the spring locking element and the magnetic means a suitable opening force required can be adjusted.
  • the magnetic means may be formed by a respective (permanent) magnet arranged on the first connection module and on the second connection module or on the one hand a magnet and on the other hand a magnetic armature, for example of a ferromagnetic steel.
  • the magnetic means on the first connection module and on the second connection module are suitable for generating the magnetic attractive force between the connection modules aligned with each other.
  • the magnetic means are realized by two magnets, they face each other with opposite poles.
  • the effect of the guide section in a magnet system consisting of magnet and armature is particularly effective.
  • the advantage of these magnet systems is that only one magnet is needed, which reduces costs.
  • These magnet systems have physically but only a much weaker lateral restoring moment.
  • the magnet can be dimensioned small even in the realization of the magnetic means by magnet and armature to save costs and space.
  • the movement of the first connection module relative to the second connection module for opening the closure device also mitigates the magnetic attraction force between the first connection module and the second connection module by removing the magnetic means from each other by moving the connection modules along the opening direction.
  • the mechanical locking is disengaged and the magnetic means are removed from each other, so that the first connection module can be easily and easily removed from the second connection module and the closure device can be opened.
  • the closure device can also be formed by a first closure part and a second closure part, which can be attached to one another in the closing direction and which each have two or more connection modules.
  • one closure part can have, for example, two first connection modules and the other closure part can have two second connection modules, or in a second variant, both closure parts can each have a first connection module and a second connection module.
  • two connection modules are arranged on each closure part in these variants, namely either two first connection modules on the one hand and two second connection modules or one first and one second connection module on the other hand.
  • the closure parts in turn lock in the closing direction and are mechanically locked together in the closed position via the two connecting modules arranged on the closure parts.
