Definitions

  • the invention relates to a mechanical-magnetic connection construction, d. H. a magnetic force assisted mechanical interlock particularly suited for closures used on bags, rucksacks and similar articles, this list is not intended to limit the scope of the invention.
  • connection constructions can be divided into two main groups.
  • the opening and closing mechanism consists of a combination of mostly positive and non-positively acting components.
  • springs are used to maintain a locked state so that closing and opening must occur against the spring force.
  • Such connection constructions are known in the art, so that reference is made only to the state of the art from the content of subclasses IPC A44B.
  • Plug buckles known in which a spring latching is formed so that a separating element, such as a wedge, with a tapered surface, the latch gradually spreads until it disengages and is released.
  • Closures such as these buckle have by the gradual overcoming of the detent on a soft opening feel, but have an unsatisfactory closing haptics, since they can be closed with considerable force and usually only with two hands.
  • connection constructions are the magnetically-acting connection structures in which the magnetic force is used to hold the connection together. These connection constructions are also well known for closures of bags and other containers of the professional world, so that here too only reference is made to the content of the subclasses of IPC E05C.
  • a positive mechanical lock usually has a mechanical component that is loaded when the lock is loaded to train, pressure or shearing.
  • the size of the mechanical resistance of this component defines the stability of the connection structure.
  • Mechanical connection structures are inexpensive to produce because z. B. in pocket closures only very inexpensive iron parts or plastic parts are used.
  • connection constructions have the property that a locking spring force has to be overcome manually during mating. Therefore, in some cases, the handling of the connection constructions is not very comfortable, so that use is made of magnetic connection constructions, because they pull themselves together due to the magnetic force.
  • haptic The force felt when closing and opening on the hand.
  • haptics The force felt when closing and opening on the hand. Especially with closures that are operated by hand, the haptics of the human hand force must be adjusted.
  • the magnet and the associated anchor must be dimensioned according to the holding force. If no special requirements are placed on the locking force and the haptics, these connections are in principle applicable.
  • closures must be oversized in certain cases, however, if z. B. safety requirements are met. This can z. B. be required in a backpack for mountaineers. This backpack may not open even if the closure is charged with a multiple of the normal locking force, which z. B. may occur in a crash.
  • closures are designed with such a requirement profile as mechanical closures, since with mechanical structures and high safety factors can be realized without much additional effort. In this respect, these connection constructions have prevailed on the mass market.
  • the opening haptic is unsatisfactory, because during the opening magnet and armature in their Hauptanziehungscardi, ie the direction in which they have moved when closing each other, are separated and thus a jerky feel is connected, since the magnetic attraction in the closed position is maximum and after strongly unlinear drops.
  • the mechanical tumbler secured here by an additional magnet-armature system in the closed position which is also opened opposite to the magnetic field, so that the feel for unlocking the shutter has a jerky course and is therefore unsatisfactory.
  • the connecting structure designed as a door opening and closing device, in which two components are displaceable relative to one another in order to hold a door closing in a retracted state of the components and to open the door in an extended state.
  • the connecting structure has a locking device for locking the components to each other in the retracted state, which is realized by a arranged on the one component groove, in which a guided on the other component ball for coupling the components engages and in the retracted state with a Locking portion of the groove in plant is.
  • the connecting structure also has a magnet-armature construction, which is formed by a magnet on the one component and metallic plates on the other component and serves to hold the door in the retracted state of the components magnetically in the closed position. When one component is extended relative to the other component, the magnetic attraction between the magnet and the armature is weakened, thereby reducing the magnetic attraction force on the door so that the door can be opened.
  • connection construction has two connection modules and serves to connect two elements, to each of which one of the connection modules can be fastened.
  • the locking piece and the locking element are designed so that the mechanical strength is sufficient depending on the actual occurring or possible loads.
  • connection construction furthermore has a magnet armature construction, wherein the magnet is arranged in one of the connection modules and the armature is arranged in the other connection module.
  • the magnetic force between armature and magnet is chosen so large that during the closing operation, the connecting modules are pulled from a predetermined minimum distance from each other, whereby the spring locking element urges against the locking piece until it snaps into engagement.
  • magnet and armature are dimensioned so that the spring force of the spring locking element is overcome. It will be clear to those skilled in the art that magnet-armature constructions can not consist of only a single magnet and a single armature.
  • a magnet-armature construction will be understood to mean any combination of magnets and armatures which are least of one another, it being known to the person skilled in the art that the armature may consist of a ferromagnetic material or may also be a magnet. Certain magnetic anchor designs not only attract, but can also repel when opposing two magnetic poles of the same name. Unless special additional conditions apply, it does not matter if the magnet is moved relative to the armature or the armature is opposite to the magnet. It is also clear that the interaction between magnet and armature is the same as between two magnet attracting.
  • connection modules When the connection modules are connected, there is a mechanical lock and also a magnetic attraction. It should be noted, however, that magnetic attraction absorbs only a negligible part of the main load of the connection.
  • the magnetic anchor construction almost exclusively serves to automatically close the connection.
  • connection module with the magnet and the connection module with the armature are displaced laterally relative to one another until the magnetic force is sufficiently weakened in order to be able to easily separate the modules by hand. This is the case when the armature surface facing the magnet has become sufficiently small. It is clear that the displacement between the magnet and the armature can also be a twist or a pivot.
  • the movable magnet is coupled to the unlocking element, i. h., With the magnet and the unlocking element is moved, wherein the term “coupled” not only means that the unlocking element must be rigidly connected to the magnet.
  • a coupling also means a connection via a spring.
  • a coupling is also present when a driver moves the unlocking, but this driver is not always applied to the unlocking, d. h., if there is a game.
  • this connecting structure has a particularly soft opening haptics.
  • the locking structure and the magnet-armature construction are each returned to their original position, in which the contraction and the snapping are possible.
  • This provision of the functional elements of the locking structure and the magnet-armature construction is effected by return means. All that needs to do is to apply a force to the component to be returned.
  • the force of a return spring is preferably used, which is biased when opening the connecting structure. It is clear to the person skilled in the art that this return spring need only be so strong in order to force the functional elements moved during opening back into their starting position. This only a very small force is required, so that only a weak return spring is required. This is one reason why the aforementioned soft and pleasant feel is retained.
  • the magnet-armature construction on a plurality of locking elements or a locking element with a plurality of locking portions With this embodiment of the invention, it is z. B. possible to better distribute the attacking load force.
  • the magnet-armature construction on a coupling device which has a game in the direction of movement of the movable magnet, so that the unlocking element is pulled by means of a stop only in the direction of the magnet when the game is used up
  • the advantage of this embodiment is that the displacement of the magnet from the armature can be greater than the distance the unlocking element has to be displaced until the spring locking element is out of engagement with the locking piece.
  • connecting structures can be built in which the displacement of the magnet from the armature due to structural constraints must be greater than the path that the unlocking element is moved.
  • the magnetic anchor construction as a coupling device on a coupling spring whose spring force along the direction of movement of the magnet and the unlocking extends.
  • the advantage of this embodiment is that with this combination of features a security against the opening of the connecting structure has been created under stress.
  • the coupling spring is dimensioned so that in the unloaded state of the mechanical locking device when moving the magnet via the coupling device and the unlocking element is pulled along. In the loaded state, however, the frictional force between the spring locking element and the locking piece is greater than the spring force, ie, the magnet can, for. B. be moved by hand without the mechanical lock opens. If the mechanical lock is relieved in this state, the spring immediately pulls or pushes the unlocking element in the opening direction so that the connection can be opened.
  • a hand-tangible object is provided on one of the connection modules, which can be placed by hand on the other connection module.
  • This embodiment of the invention is suitable for. B. for connecting a bicycle lamp with the bicycle handlebar.
  • the anchor is directly connected to the object in one piece.
  • the magnet-armature construction in a connection module at least one magnet and in the other connection module at least one ferromagnetic armature or poled on attraction magnet. This arrangement is preferred when a low cost connection is needed.
  • This arrangement is preferred when a robust connection is required, because in this magnetic anchor construction no mechanical contact of the magnetic surface with the surface of the armature occurs, so that damage to the sensitive magnetic surface z. B. is avoided when repeated shifting, even if foreign objects such. B. sand in between.
  • This arrangement is preferred when the magnetic force is particularly good to be exploited, which is achieved by the bundling of the magnetic field lines in the magnetic guide plate.
  • the magnet-armature construction in each connection module on a magnet with ferromagnetic baffles, wherein the baffles in the closed position are attractive. This arrangement is preferred when a robust connection with a high tightening force is required in the closed state, and when at least low repulsion is desired when opening.
  • the magnet-armature construction at least two each opposite magnets, which are both in a closed position of the connection in a tightening position and in the open position in a repelling position. This arrangement is preferred when a connection with high tightening force in the closed state and high repulsion force is required when opening.
  • the magnet-armature construction has a magnet arrangement in which in each connection module, a magnet and a ferromagnetic armature are arranged so that in the closed state, the magnets are in opposition to the armature and are polarized so that in the open state, the magnets are polarized on repulsion.
  • This arrangement is preferred when a cost-effective connection with high tightening force in the closed state and low repulsion force is required when opening.

  • the ejection force arises when either the spring locking pieces were urged from a straight position to an oblique position and the resulting skew the spring tension of the spring locking element has been partially converted into an ejection force, insofar as the second sliding surface allows sliding with low friction of the elements to each other, or if the unlocking presses with the second sliding surface on a slope on the spring locking element or an obliquely formed second sliding surface on the unlocking with the spring locking element interacts or combinations of the aforementioned possibilities, which convert by means of known to those skilled chamfers and sliding surfaces, the spring tension at least partially into an ejection force.
