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 module as well as on the second connection module in each case a magnet or on the one hand a magnet and on the other hand a magnetic armature are arranged, the production of the mechanical latching and thus the transfer of the closure device in the closed position is magnetically supported. If appropriate Dimensioning of the magnets, 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 exactly aligned with each other, a magnetic attraction force is applied
  • connection modules Alignment of the connection modules to each other, ie, the magnetic attraction attracts the connection modules with alignment of the magnetic means to each other 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.
  • 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. This object is achieved by an article having the features of claim 1.

  • 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 direction vector is mathematically decomposable in direction vector components, one of which is directed counter to the opening direction.
  • a second directional vector component perpendicular to the first directional vector component may point in the closing direction.
  • directed guide portion is achieved that even with an offset of the connection modules when attaching to each other, so for example when the first connection module is offset in the opening direction relative to the second connection module, a slight and largely automatic closing of the closure device takes place.
  • the magnetic means used can be made small, since the orientation of the connection modules to each other during Conversion into the closed position no longer takes place solely by the magnetic means, but in a guided manner by means of the guide section. An oversizing of the magnetic means is no longer necessary so that small magnets can be used with a small space requirement for the realization of the magnetic means.

Abstract

L'invention concerne un dispositif de fermeture destiné à relier deux pièces, avec un premier module de liaison (1) et un deuxième module de liaison (2), le premier module de liaison étant disposé dans la direction de fermeture contre le deuxième module de liaison et étant encliqueté mécaniquement avec le deuxième module de liaison dans la position de fermeture, et avec des moyens magnétiques (10, 20) qui, afin de faciliter le transfert du premier module de liaison dans la position de fermeture, exercent une force d'attraction magnétique entre le premier module de liaison et le deuxième module de liaison. Le premier module de liaison, par un mouvement du premier module de liaison ou d'une partie du premier module de liaison dans une direction d'ouverture, qui diffère de la direction de fermeture, peut être détaché du deuxième module de liaison. Il est prévu pour ce faire au moins un segment de guidage (240A, 240B) disposé sur le deuxième module de liaison afin de guider le premier module de liaison dans la position de fermeture lorsque le premier module de liaison est placé sur le deuxième module de liaison. Ledit au moins un segment de guidage, au moins par une composante du vecteur de direction (FY), est orienté à l'opposé de la direction d'ouverture (Y).
