Definitions

  • the abutment engages the associated second element in point or line contact at a surface thereof which extends substantially normal to the plane of movement of the displaceable element, and the abutment is spaced from the locus at which the force of the spring acts upon the other second element by. a distance which decreases with increasing displacement of the movable first element from its rest position.
  • the present invention relates generally to a ski binding construction, more particularily to an arrangement for the elastic retention of ski binding components, more particularly safety ski binding components.
  • ski bindings it is frequently necessary to maintain a component, for instancea sole holder, in such a manner in a predetermined position that the component will become movable against the action of a biasing element in one or in two mutually opposite directions only after an initial predetermined force has been overcome. It is immaterial in this connection whether such movement is to take place in direction transversely or normal to the longitudinal axis of the ski, or in any other direction.
  • the prior art has proposed to so pivot the component to be displaced by means of two pivoting arms to anotherzcomponent of the binding which is at least at times connected with ski, so that a four-bar kinematic chain is obtained the movable component or coupling of which consitutes thecomponent which is to be displaced.
  • the kinematic chain is maintained in its rest position by biasing means which act on at least two of the four bars or elements ofthe chain.
  • biasing means which act on at least two of the four bars or elements ofthe chain.
  • springs or spring-loaded snap-in ball couplings may be used for this purpose which act via suitable abutments on surfaces of turnable components of the arrangement.
  • An additional object of the invention is to provide such an arrangement which operates with a minimum of frictional resistance.
  • onefeature of the invention resides in a ski binding having a four-bar kinematic chain including two opposite first elements one of which is to be secured to a ski and the other of which carries a boot-engaging portion and is displaceable in a predetermined plane from and to a rest position, and two opposite second elements linked with the first elements, in a combination which comprises pretensioned energy storing means acting between these second elements, and abutment means interposed between the energy storing means and one of the second elements.
  • the abutment means engages the one second element in at most line contact at a surface thereof which extends substantially
  • the difficulty with the prior art proposals is that normal to the aforementioned plane and such engagement is effective at the latest on initiation of the displacement of other first element.
  • the abutment means is spaced from the locus at. which the energy storing means acts upon the other of the second elements by a distance which decreases with increasing displacement of the other first element'from the rest position thereof.
  • Theconstruction according to the present invention has significant advantages. lnthe first place, the frictional force which arises on displacement of the displaceable first element and which must be overcome, is very small because the area on which this force must be transmitted is reduced to a point or to a line.
  • the force required for effecting the displacement of the displaceable first element corresponds to all intents and purposes to the balancing force of the energy storing means, so that it can be precisely predetermined.
  • F urthermore, a contamination of the arrangement with dirt, slush or the like, or even various degrees of lubrication which may be encountered at different times or under different operating conditions, will remain largely without influence upon the force which counteracts the movement of the displaceable first element 'from its rest position.
  • the balancing force assures that the arrangement will have a damping effect on the useful movements of the ski boot with reference to the ski, and will always returnthe ski boot to its normal starting position on the ski. It is well known that such movements of the boot with reference to the ski take place almost constantly during skiing but of course are not usually'sufficient to trigger a release of the release binding, if the latter type of binding is provided.
  • a release arrangement may be provided so that if the movement of the boot with respect to the ski exceeds the length of the permissible path, the binding will release Because the release force corresponds to the biasing force which obtains when the end of the aforementioned path has been reached, it is clear that this force is to all intents and purposes independent of the condition of contamination or lubrication of the binding.
  • the point or line-contact is obtained by at least one edge, that is by a knife-like abutment edge, so that the cooperation between the abutment and the second element of the kinematic chain upon which the abutment acts, is essentially that of the beam of the scale with the knife edge on which it is balanced.
  • the invention also proposes that the biasing force exerted by the energy storing means may cooperate in both directions with an abutment, in which the abutments are provided with knife-edged abutment edges which abut againstthe respective second elements in response to movement of the displaceable first element in one or in the opposite direction.
  • each of the abutments with at least two such abutment edges, which are located at opposite sides of and equidistantly spaced from the axes along which the biasing action of the energy storing means is transmitted, such equidistant spacing obtaining when the displaced first element is in its rest position; in this case a force of identical magnitude is opposed to the displacement of the displaceable first element as it moves from and to its rest position; If a safety release binding is provided with the arrangement according to the present invention, then such release will take place in both directions of displacement of the first element with a constant and identical-magnitude force.
  • one abutment has an abutment portion, such as an abutment edge, which is located either on the axis along which the force of the energy storing means is exerted or which crosses this axis, whereas the other abutment has at least two abutment edges equidistantly spaced from this axis at opposite sides thereof.
  • the biasing force may be made adjustable.
  • a variable damping force or resistance to triggering of the release binding can be obtained which is of equal magnitude in both directions of displacement of the displaceable first element.
  • one of the abutments is provided with two or more pairs of abutment edges which are located at opposite sides of the aforementioned axis, with the abutment being turnable about this axis so that in dependence upon such turning, the one or another pair of abutment edges can engage the respectively associated second element. Edges of each pair are equidistantly spaced from the axis, but this spacing is different in different pairs so that. depending upon the distance from the axis.
  • the biasing force can be varied in that the pretension of the energy storing means is influenced sooner or later as calculated from the moment at which displacement of the displaceable first element begins.
  • the abutment means may utilize two abutment elements each of which may have one abutment edge located on the aforementioned axis, and one of them may have at least one additional abutment edge which is Iaterally spaced from this axis. It is possible to utilize two sets of such abutment elements, and to provide each of them with energy storing means, for instance. in the form of a helical spring, with the biasing force exerted by one of the energy storing means being different from that exerted by the other.
  • both abutments of each set in the aforementioned embodiment each have an abutment edge which is located on the respective axis along which the energy storing means transmits its biasing force, whereas the other abutment has two or more abutment edges which are spaced at different distances from these axes.
  • the last-mentioned edges will be turnable with respect to and about these axes.
  • Both abutments may also be provided with several pairs of such edges which can be turned about the axis.
  • abutment edges may be in the form of continuous arcuate curves to thus permit an essentially continuous adjustment analogous as in the case of an adjustment of the biasing force.
