Definitions

  • the invention relates to a toe piece according to the preamble of claim 1.
  • the aim of the invention is to remedy this and to design the mechanism for the automatic adaptation of the toe to the respective shoe sole thickness in the case of a toe of the type mentioned at the outset so that as little friction as possible occurs.
  • the front support wall of the bearing part has two sections adjoining one another in the vertical direction, the lower section and the upper section enclosing an obtuse angle with one another, a tilting edge is formed around which the bearing part adapts to the Shoe sole is pivotable.
  • the embodiment according to the features of claim 2 allows, after exhausting the tilting movement possible by the tilting edge, a further pivoting of the bearing part for the release of the binding.
  • FIG. 1 shows the front jaw partially torn open
  • FIG. 2 shows a longitudinal section through the front jaw in the ready-to-start position of the ski binding, with an indicated ski boot
  • FIG. 3 shows a representation like FIG. 2, with a ski boot inserted, with a thicker one Sole
  • FIG. 4 the same view with the sole holder pivoted a little more
  • FIG. 5 the binding with the sole holder pivoted to the maximum
  • FIGS. 6 and 7 a partial view from the rear, the binding in FIG. 6 in the rest position and in FIG. 7 laterally is shown pivoted upwards.
  • FIG. 1 and 2 show the toe 1 according to the invention in the position ready for entry. It has a housing 2, which is fastened to a ski 50 by means of only indicated screws 51.
  • a release spring 40 is accommodated in the housing 2, the pretensioning of which can be adjusted in a known manner by an adjusting device 43.
  • the release spring 40 is arranged between a spring plate 41 and, with the interposition of a bearing bush 42, a vertically running rear transverse wall 3 of the housing 2.
  • the release spring 40 is penetrated in the axial direction by a pull rod 10, one end 11 of which cooperates with the adjusting device 43 and the other end 12 of which is connected to a substantially vertically extending release plate 13.
  • the trigger plate 13 has at its lower end 14 a control surface 15 directed towards the ski tip and a stop 16 pointing in the direction of the shoe 60.
  • a first curve 5 closes at the top of the vertically running rear transverse wall 3 of the housing 2 and at it Section 6 running horizontally to the rear.
  • the bearing part 20 is frame-shaped when viewed from the rear, that is to say provided with a through opening 21 for the pull rod 10, and — viewed from the side — has approximately the shape of a C.
  • the vertically extending portion of the C is formed by the support wall 22 and is equipped with a front support surface 23 and a rear support surface 24.
  • two axes 34 for angle levers 35 are arranged symmetrically to the longitudinal central axis of the toe piece 2.
  • the shorter lever arms 36 of the two angle levers 35 are supported on the one hand on the release plate 13 and on the other hand on the rear support surface 24 of the bearing part 20.
  • the longer lever arms of the angle lever 35 are designed as sole holders 37 for contacting the sole 61 of the ski boot 60, which is only indicated in the drawing.
  • the front support surface 23 of the bearing part 20 has two sections adjoining one another in the vertical direction, the lower section 25, viewed in the ready-to-enter position of the front jaw 2, abutting on the rear side 4 of the rear transverse wall 3 of the housing 2.
  • the upper section 26 forms an obtuse angle ⁇ with the lower section 25. Between the upper section 26 and the lower section 25, the bearing part 20 has a tilting edge 27.
  • the upper leg 32 of the bearing part 20 is provided in the section of the longitudinal central axis with a surface 28 which is inclined towards the rear and downwards.
  • the transition between the upper section 26 of the front support surface 23 and the surface 28 which is inclined backwards and downwards is designed as a further curve 29.
  • the bearing part 20 is fork-shaped in the plan view in the region of the longitudinal center axis and has a recess 30 open towards the front and a projection 31 directed towards the rear.
  • the recess 30 is a corresponding wedge-like projection 7 v. assigned to the housing 2.
  • a travel limiter 8 facing the stop 16 of the release plate 13 is also arranged on the housing 2.
  • the lower section 25 of the front support surface 23 of the bearing part 20 lies flat against the rear side 4 of the rear transverse wall 3 of the housing 2 and the bearing part 20 touches with its curve 29 the horizontally rearward section 6 of the housing 2.
  • the bearing part 20 tilts slightly counter-clockwise around the tipping edge 27.
  • the release spring 40 is slightly compressed.
  • the bearing part 20 with the angle levers 35 automatically returns to the starting position after removal of the ski shoe 60 and it is possible to use ski shoes with a thicker or thinner sole without any additional manipulation.
  • FIGS. 4 and 5 show how the bearing part 20 and the angle lever 35 are pivoted in the event of an increased force directed upwards, for example in the event of a backward or backward turn.
  • the bearing part 20 is pivoted further about the tilting edge 27 against the force of the release spring 40.
  • the release plate 13 detaches itself from the shorter lever arms 36 of the angle lever 35. This initially enables the angle lever 35 to be pivoted without force for sideways release.
  • the wedge-shaped design of the projection 7 in cooperation with the recess 30 allows the bearing part 20 to pivot laterally (see FIGS. 6, 7). An excessive pivoting of the sole holder 37 and thus an undesired release of the ski boot 60 is avoided by the fact that the pivoting path of the bearing part 20 is limited by the impact of the stop 16 of the release plate 13 on the path limiter 8.

Abstract

Une mâchoire antérieure (1) comprend un boîtier (2) dans lequel est logé un ressort de déclenchement (40). Le ressort de déclenchement (40) agit sur une barre de traction (10) qui le traverse et qui à son tour agit par l'intermédiaire d'une plaque de déclenchement (13) sur les bras plus courts (36) de deux leviers coudés (35) pivotant sur une pièce de support (20) autour d'axes verticaux (34), alors que les bras plus longs des leviers forment des organes (37) de retenue de la semelle. La pièce de support (20) est pourvue d'une ouverture traversante (21) pour la barre de traction (10) et comprend une surface antérieure d'appui (23) qui s'appuie au moins en partie sur une paroi transversale postérieure (3) du boîtier (2). La paroi transversale postérieure (3) du boîtier (2) se termine par une section (6) qui s'étend à peu près horizontalement vers l'arrière. La surface antérieure d'appui (23) de la pièce de support (20) comprend deux sections (25, 26) adjacentes dans le sens de la hauteur. La paroi transversale postérieure (3) du boîtier (2) est pratiquement verticale. En outre, la section inférieure (25) et la section supérieure (26) forment ensemble un angle obtus (alpha) et la section supérieure (26) de la surface antérieure d'appui (23) se termine par une surface (28) inclinée en arrière vers le bas.
