Definitions

  • the invention relates to a safety ski binding, as specified in the preamble of claim 1 and claim 4.
  • a known binding of this type which is described in DE-OS 31 02 010, uses two pairs of toggle levers to lock the sole holder in the driving position. But these are difficult to monitor.
  • the known heel holder is relatively complicated in its construction.
  • the object of the invention is to eliminate the disadvantages of the known design and to create a safety ski binding which is simple to manufacture and assemble, the manufacture of toggle levers becoming superfluous.
  • the measure of claim 2 ensures that the heel holder can be easily installed.
  • claim 3 has the advantage of an arrangement of the control cam protected against snow and dirt for triggering in a plane parallel to the top of the ski and the associated roller.
  • the structure of the heel holder is further simplified by the feature of claim 5. It is aimed in this direction also the measure of claim 6.
  • FIG. 1 is a vertical longitudinal central section through the rear end of the ski binding in the driving position according to the first embodiment and FIG. 2 is a plan view of the rear end of the ski binding partially cut along the line II-II in FIG. 1.
  • Fig. 3 is a vertical longitudinal section through the heel holder in the open position after a frontal fall and in Fig. 4 the same section is shown after a fall.
  • FIGS. 5 and 6 show a longitudinal central section or a representation corresponding to FIG. 2 of a further embodiment in the driving position.
  • the safety ski binding shown in FIGS. 1 to 4 is a so-called plate binding. It has a sole plate 1 which can be pivoted about a ski-fixed pivot in a horizontal plane. On the ski, which is not shown in the drawing, there is a base plate 2, which carries the pivot. At the front end of the sole plate 1, a toe piece, not shown, is attached, which is not the subject of the present invention. The rear end of the soleplate 1 wears a heel holder designated 3 in its entirety.
  • a body 4 On the base plate 2, a body 4 is also attached, which carries a control cam 4a on its side facing the pivot. On the opposite side, the body 4 has a rib 4b which engages in a groove 5, which is circular in plan view, in the housing 6 of the heel holder 3. Of course, the pivot pin forms the center point for the circular arc of the groove 5. Between the body 4 and the sole plate 1 there is a gap for a roller 7.
  • the housing 6 of the heel holder 3 has on the side facing the pivot a fork-shaped extension 8 which is screwed onto the sole plate 1. Furthermore, in the housing 6 there is a bore 9 running parallel to the top of the ski and in the longitudinal direction of the ski, in which on the one hand an annular piston 10 provided with two lateral projections 10a and on the other hand another piston 11 which is guided in a bore of the annular piston 10 is accommodated.
  • the annular piston 10 is acted upon by a first spring 12, the preload of which is adjustable in a manner known per se. Coaxial with the first spring 12 is a second spring 13, which acts on the piston 11. This spring 13 can also be adjusted in its pretension.
  • an axis 14 is mounted above the bore 9 there is a transverse bore in which an axis 14 is mounted.
  • a unit is articulated to this, which consists of a sole holder 15, a step spur 16 and a release lever 17.
  • the unit bears an egg on the inside ne control cam 18.
  • an intermediate member 19 is mounted on the axle 14, which is supported on one side on the end face of the annular piston 10 (see FIG. 2), and which carries an axle 21 on its underside, on which an intermediate lever 22nd is mounted, which rests on the one hand on the inner piston 11 and on the other hand on a one-armed locking rocker 23.
  • the locking rocker 23 is mounted on an axis 24 which passes through the fork-shaped extension 8 which is screwed onto the soleplate 1 and on which a two-armed control lever 20 is also mounted.
  • the two-armed control lever 20 bears against the intermediate member 19 with projections 20a.
  • the control lever 20 also carries a downwardly projecting axis 20b on which the roller 8 is mounted.
  • the sole holder 15 In the driving position, the sole holder 15 is held by the first spring 12 and the second spring 13.
  • the control curve 4a is approximately V-shaped, so that the roller 7 tries to keep the sole plate 1 under the influence of the spring 12 in the longitudinal direction of the ski in the driving position.
  • step spur 16 and release lever 17 swivels clockwise in FIG. 1, which results in the ski boot being released (see FIG 3).
  • the free end of the locking rocker 23 slides along the control cam 18 and pushes the two pistons 10 and 11 back via the intermediate lever 22.
  • a release of the sole holder 15 does not take place in the case of a pure fall on the heel holder 3.
  • the spring 12 is already compressed somewhat, so that the sole holder 15 is only loaded by the second spring 13, which facilitates the release of the ski boot.
  • the release lever 17 In the event of an arbitrary release, the release lever 17 is pivoted clockwise. The end of the locking rocker 23 slides along the control cam 18, which results in a compression of the two springs 12 and 13. As soon as the release point of the heel holder 3 is reached, the release lever 17 automatically pivots into the open position.
  • This heel holder 3 ' also has a housing 6' which is screwed onto the soleplate 1 'by means of a fork-shaped extension 8'.
  • a bore 9' running parallel to the top of the ski in the longitudinal direction of the ski, in which an annular piston 10 'is guided so as to be secured against rotation.
  • an annular piston 10 ' In the bore of this annular piston 10 ' another piston 11 'out.
  • Each piston 10 'or 11' is acted upon by a compression spring 12 'or 13'.
  • the springs 12 'and 13' are nested coaxially.
  • the preload of the spring 13 ' is adjusted by means of a screw 30 which is screwed into a spring plate 31 which is supported on the piston 11'.
  • the screw 30 rests with its head on a threaded sleeve 32 which is screwed into a further spring plate 33 which is opposite the spring plate 31.
  • the threaded sleeve 32 is supported on a transverse wall of the housing 6 'and penetrates a bore in the same.
  • the spring plate 33 has a lateral extension which protrudes into a recess 6'a of the housing which runs in the longitudinal direction of the ski and is provided with a scale and thus prevents the spring plate from rotating and which serves to display the set spring preload.
  • An intermediate member 19 ' is also mounted on the axis 14', which is supported on the right side in FIG. 5 on the end face of the annular piston 10 'and which bears an axis 21' in its lower region.
  • an intermediate lever 22 ' is mounted, which is on the one hand on the inner piston 11' and on the other hand abuts on a locking rocker 23 '.
  • This locking rocker 23 ' is mounted on an axis 24' which passes through the fork-shaped extension 8 'of the housing 6'.
  • the intermediate member 19' in the heel holder 3 ' the intermediate member 19' carries a downwardly projecting axis 19'a on which a roller 7 'is mounted which rolls on the control curve of the body 4'.
  • the intermediate member 19 'on the side facing the housing 6' carries two cams 19'b which bear against the end face of the annular piston 10 'running perpendicular to the axis of the bore 9'.
  • the release lever 17 ' is mounted on an axis 34 which is anchored in the region of the upper end of the locking rocker 23'.
  • the trigger lever 17 ' is approximately U-shaped in cross section.
  • the function of the heel holder 3 ' essentially corresponds to that of the first exemplary embodiment.
  • the pretension of the inner spring 13' is changed by turning the screw 30.
  • both springs 12 'and 13' are changed in their pretension, especially since both springs are supported with their right ends (see FIG. 5) on the spring plate 33.
