Definitions

  • the present invention relates to a heel clamp for a ski binding.
  • heel clamps which hold the ski shoe on the ski in a suppressed position and which release when the shoe heel is stressed in a vertical direction. Release entails a relaxing of the ⁇ tightener spring.
  • heel clamps are known in which the ski shoe is disengaged by a stress on the heel in a vertical and horizontal direction, but in these the ski shoe rotates horizontally out of the ski binding and the tightener spring remains tightened. In these known construtcions, bone fractures occur, because the point of disengagement cannot be adjusted exactly.
  • the heel clamp of the invention includes a clamp housing and a boot suppressor pivoted on the clamp housing.
  • a tightening lever is pivoted on the clamp housing.
  • a tightener spring provides a clamping force to hold the suppressor against the heel in a locking position.
  • the suppressor ⁇ is tiltable in the vertical direction against the clamp housing and/or is simultaneously displaceable and/or swingable in the horizontal direction. The locking of the tightener lever is released by any one of the suppressor movements.
  • FIGURE 1 is a longitudinal section of a side elevation of a first embodiment of the heel clamp
  • FIGURE 2 is a top plan view thereof, partly in section;
  • FIGURE 3 is a section along line III- III of FIG- URE l;
  • FIGURE 4 is a side elevation of the rst embodiment
  • FIGURE 5 is a longitudinal section of a side elevation of a second embodiment of the heel clamp
  • FIGURE 6 is a top plan view of the embodiment shown in FIGURE 5, partly in section.
  • the rst embodiment of the present invention comprises a ski 1 on which is attached a base plate 2.
  • This base plate 2 includes a foundation 3.
  • Clamp housing 5 is slidably mounted via rivet 30 in the base plate and pin 4 in slot 23 of the foundation.
  • Tightener lever 7 is pivotably mounted to the clamp housing on pin 6. Connected to the tightener lever 7 at pin 8 is the eye of bolt 9. There is an adjusting nut 10 on the thread of .this bolt and attached to this nut is spring 11, which has at its other end helical windings of reduced diameter. Spring 11 is attached to the base plate at its reduced end by way of bolt 12. On one end of the clamp housing 5 is arran-ged the suppressor 13. This suppressor 13 can tilt about the pin 27 and is also, as shown particularly in FIGURE 2, laterally shiftably mounted on pin 27. The suppressor 13 has pivoted to it two disengaging levers 14.
  • the latch 18 moves out of engagement with the blocking nose 20 of the tightener lever 7. This disengaging is also attainable by a pressure in direction of arrow 21 on the lever 7. This causes the auxiliary lever 22 to push away the latch 18 from its engagement with the blocking nose 20.
  • the auxiliary lever 22 is swingably arranged on the tightener lever 7 and holds the blocking latch 18 away from the blocking nose 20 until the nose 20 reaches a position above the blocking latch 18.
  • FIGURE 3 shows a symmetrical arrangement of a heel clamp with the position of the spring 19 surrounding the pin 4 and the arrangement of this pin in the side foundations 3.
  • FIGURE 4 shows a side elevation, in which the foundation 3 is evident. In both foundations 3 there are inclined slots 23 for guiding the pins 4.
  • the spring 11 shifts the tghtener lever 7 and therefore also the clamp housing in an obliquely upwards direction.
  • FIGURE 4 also shows the heel 34 of a ski boot in position on a ski. The suppressor is contoured to fit again and over the heel of the boot ⁇
  • the FIGURES 5 and 6 show another embodiment of the arrangement of the supppressor 13 on the clamp housing 5. Of special interest is the connection of the suppressor of the pullrod 16.
  • the second embodiment achieves movement of the pullrod toward the suppressor when the suppressor moves laterally in either direction because parts 26 are at their deepest positions in the notches 25 in FIGURE 6 and movement in either direction from this geometrically extreme position results in a unidirectional movement of the pullrod.
  • the ski boot is placed in the binding when the tightener lever 7 is released from engagement with latch 18. Then, counterclockwisely in the drawing, the tightener lever is rotated about pivot pin 6, until latch 18 engages the blocking nose 20. The blocking nose and latch are on the underside of the tightener lever.
  • spring 11 pulls clamp housing and suppressor into engagement with the heel. Because of slot 23 and pin 4, the movemen of the suppressor pushes the boot into the toe binding while at the same time bearing downwards on the upper ridge of the heel.
  • Horizontal perpendicular directions mean the two vector directions lying in the plane of the sole of a ski boot clamped to a ski and lying perpendicular to the ski.
  • Normal position of the ski boot means that position of the boot relative to the ski when the boot is clamped to the ski, but not skiing is being done. When skiing is being done and a fall occurs, excessive thrusts on the boot can move the boot out of its normal position.
  • the present invention is also operable with those types of boots now conventional on the North American continent having a concave groove in the rear wall for use with a cable in other types of bindings.
  • the suppressor 13 preferably is to be built outwards into a nose mating with the groove. This may be in addition to the top portion of the suppressor 13, or in lieu thereof.

  • a clamp as claimed in claim 1, said means to translate comprising:
