  • the spring is used in conjunction with an associated contour on the lever for the composite formation of the bistable position assurance unit.
  • the spring is a leg spring with two spring legs.
  • To support and support the spring or leg spring is a pin which passes through an associated spring coil.
  • a locking system with multi-stable component-spring element device is described.
  • an eccentric portion is provided on a component which is pivoted along a movement path between at least a first stable position and a second stable position.
  • the spring element between a fixed bearing and a floating bearing is clamped and formed from a single-straight spring wire, which is bent at both ends by 90 °.
  • the procedure is consistently that the spring element performs more or less pronounced movements when taking the at least one stable position or when changing position.
  • the procedure is such that the spring element carries out a more or less pronounced linear movement, at least in the area of the movable bearing.
  • the described rotary and / or linear movements of the spring element are observed in addition to the already obligatory and elastic deformations of the spring element and occur.
  • fatigue problems of the spring element may occur during intensive and long-term use, or there is a risk that the spring element does not or no longer completely fills the desired function. That is, on long time scales in the state of the art under certain circumstances, the functional safety is at risk.
  • the invention aims to provide a total remedy.
  • a locking system has the features of the first claim.
  • the spring element is made predominantly of a straight spring wire.
  • it is usually the procedure that the spring element is clamped at each endpoints.
  • an intermediate region remaining between the two end points can be elastically deformed, the lever interacting with the spring element providing the desired elastic deformations of this intermediate region.
  • a spring element designed as a straight spring wire which adjoins Endpoints is clamped.
  • any linear movements, rotations, etc., of the spring element are not permitted in the beginning of operation, so that the previously described fatigue problems can not or no longer occur.
  • the elasticity of the spring is used in the invention in order to represent the at least one stable position of the lever can.
  • the position assurance unit is designed bistable. That is, the lever can be pivoted into two stable positions, wherein the two respective stable positions are defined by the interaction of the lever with the spring element respectively. This is done in detail by the fact that the spring or the spring element engages through the opening in the lever and the opening is designed so that the described pivoting movements of the lever are allowed. In most cases, the lever can be pivoted from one stable position to the other stable position, wherein the angular range between these two stable positions represents the predetermined swivel angle range,
  • the opening in the lever has two substantially opposite and spaced contact surfaces for the spring element.
  • the spring element In order to allow the Schwenkbarkelt of the lever against the spring element penetrating him taking into account the predetermined pivoting angle range, have the antireflective surfaces over a distance to each other, which is a multiple of a diameter of the spring element.
  • the spring element is predominantly designed as a straight spring wire or produced predominantly from such a straight spring wire.
  • the straight spring wire typically has a cylindrical shape with a circular cross-section and associated diameter. The diameter of the spring element fits usually two or even three times side by side between the two defining the opening in the lever contact surfaces.
  • the distance between the two said contact surfaces for example, twice, three times, etc., the diameter of the spring element.
  • decimal multiples are conceivable and are included, for. B. such that the distance is 1.5 times, 2.5 times the diameter of the spring element.
  • the two defining the opening in the lever contact surfaces are designed differently.
  • the contact surfaces are, on the one hand, a deflection surface and, on the other hand, a stop surface.
  • the deflection surface abuts against the spring element during all pivoting movements of the lever.
  • the stop surface moves only to define the stable position against the spring element.
  • the deflection deflects the spring element or the straight spring wire between the two stable positions on one side, that is in one direction. Because the spring wire or the spring element is clamped at its end points in each case, so that the spring element acting on the deflection surface for the described elastic deformation of the spring element in one direction, that is one-sided, provides. In the respectively stable position, however, the spring element undergoes substantially no deflection. That is, in this stable position, the deflection surface does not or practically does not act on the spring element.
  • the tilting point corresponds to the fact that the spring element generates a maximum of the lever counteracting force by the maximum deflection, so that the lever is always anxious to avoid in one or the other direction compared to the tipping point.
  • the opposing forces built up by the spring element are designed to be smaller than in the region of the tipping point.
  • the tipping point is centered between the two stable positions. This central position is compared to the predetermined swivel angle range. In addition to this predetermined swivel angle range with end-side stable positions and central tilting point, an overstroke range is observed beyond the stable position.
  • the spring element undergoes a two-sided deflection. That is, the spring element is deflected in the overstroke in two directions, namely radially outwardly and radially inwardly compared to a pivot point or a rotation axis of the lever mounted on the relevant axis respectively pivot lever. In contrast, the spring element experiences in the tipping point and between the two stable positions only a deflection radially outward.
  • the spring element builds up particularly strong and acting on the lever counter forces, which the lever in the direction of the stable Apply position back.
  • the two Studentshub Kunststoffe each beyond the stable position thus represent as it are resilient end stops, so that the lever is not expressly against any mechanically fixed stops .. Rather, the end stops - if you will - designed resilient, namely, are in the form of each described Kochhub Kunststoffe in front.
  • These overstroke ranges correspond to a two-sided deflection of the spring element and thus to the fact that the lever located in the overstroke region experiences a force acting on it in the direction of the stable position.
  • the lever is typically a pivoting lever mounted on the axis already mentioned.
  • the lever is usually equipped with a motor drive, which ensures a certain self-locking of the lever. That is, the opposing forces built up by the spring element assist in a motorized movement of the lever in the direction towards the stable position or counteract a motorized movement of the lever beyond the stable position.
  • the opposing forces of the spring element which then arise in the associated overstroke range ensure that the motor drive and with it the lever are, as it were, turned back. This explains the function of the thus realized elastic end stops.
  • the locking system according to the invention can be used particularly advantageously for the realization of a worm drive. That is, the lever including the motor drive advantageously acts as a worm drive, which can be used, for example, in conjunction with a locking lever, an anti-theft lever, etc. of a motor vehicle door lock.
  • mechanical end stops are not required because the locking system according to the invention is equipped with alternative resilient end stops. This increases the life and reliability, especially since fatigue of the spring element according to the invention - in contrast to the prior art - are no longer observed.
  • the main benefits are the main benefits.
  • a locking system is shown, in this case partially a motor vehicle door lock.
