Definitions

  • FIG. 1 illustrates a longitudinal section through magnetic heel holding means according to the invention.
  • FIG. 2 is a top view of the heel holding means of FIG. 1.
  • FIG. 3 represents a section taken along the line III- III of FIG. 2.
  • FIG. 4 is a section similar to that of FIG. 3 through a modified heel holding means according to the invention.
  • FIG. 5 diagrammatically illustrates a side view of a mechanical boot tip holding means according to the invention.
  • FIG. 6 shows a top view of the boot tip holding means of FIG. 5.
  • the ski safety binding according to the present invention is characterized primarily in that the magnetic holding means is equipped with a tongue which extends below the sole of the ski boot and which together with an angle member forms a U-shaped clamp, said angle member extending over a portion of the heel of the ski boot. In this way the occurrence of tilting moments is prevented.
  • the angle member engaging the heel is adjustable relative to the tongue.
  • the tongue is arranged in a recess provided in the base plate of the magnetic holding means whereby a lateral slipping of the ski boot is prevented.
  • the U-shaped clamp formed by the tongue and the angle member is expediently by means of a bolt connected to the magnet or the soft iron plate in such a way that the axis of the bolt is in alignment with the axis of the magnet so that the point of attack of the force tending to open the magnetic holding means will always be located in the center of the magnet.
  • the bolt has its lower end provided with a thread or with a groove for a spring ring.
  • an elastic disc is arranged below the head of the bolt, said disc acting in the manner of a ball joint. Furthermore, the elastic disc is adapted to absorb shocks. The elastic disc will prevent the soft iron plate from detaching itself from the magnet in response to the occurrence of short, shock-like forces which act in a direction counter to the holding force of the magnet.
  • the bolt is hollow and has its. upper portion provided with an inner thread receiving a screw while below said screw there is provided a pressure spring which through the intervention of a pin exerts a pressure upon the magnet which pressure is directed counter to the direction of the magnetic force.
  • a pressure spring which through the intervention of a pin exerts a pressure upon the magnet which pressure is directed counter to the direction of the magnetic force.
  • the effective magnetic force may be varied. The stronger the pressure exerted by the pressure spring, the weaker will become the effective magnetic holding force.
  • the holding force may be selected precisely in conformity with the holding force necessary for the respective skier.
  • the magnetic holding force may also be controlled by exchanging the soft iron plate.
  • the salesman will determine the thickness of the soft iron plate in conformity with the requirements of the respective buyer so that accidents due to an incorrect adjustment of the release force can no longer occur.

  • thinner soft iron plates are supplemented by a plate of non-magnetizable material the thickness of which is so selected that the space between the soft iron plate and the elastic intermediate layer is completely filled.
  • the clamping member of the magnetic holding means is provided with a longitudinal bore for the passage of a bolt which establishes the connection between the U-shaped clamp formed by the tongue and the angle member on one hand and the magnet or soft iron plate on the other hand. In this way a certain displacement of the clamping member relative to the magnet or soft iron plate is possible. Such displacement may occur when skiing through a dip in the terrain inasmuch as the ski will bend in such circumstances.
  • an elastic abutment member is inserted into the base plate. The end of the tongue rests against said abutment member so that a shortening of the distance between the magnet and the mechanical holding means when skiing through a dip will be compensated for.
