Definitions

  • the invention relates to a safety ski binding, as specified in the preamble of claim 1 and claim 5.
  • a known embodiment 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. These are difficult to assemble and, moreover, the known heel holder is comparatively complicated in its construction, whereby set trigger values cannot always be maintained due to internal friction.
  • 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 two guide rods for the compression springs which serve to trigger in a horizontal plane, are determined. This precisely defines the points of application of the two springs on the control lever.
  • the construction according to claim 5 is characterized in that the force of the spring, which is intended for the pivoting of the sole holder in the vertical direction, is transmitted on both sides of the control lever to the locking rocker.
  • the spring can engage in the middle in a horizontal plane on the control lever, which has advantages with regard to a symmetrical configuration.
  • the measure of claim 7 makes it possible that the adjusting screw, which is used to adjust the pretension of the pressure spring loading the roller for triggering in a horizontal plane, can practically only be adjusted by a trained fitter. An adjustment of the adjusting screw by a layperson is practically impossible. However, accidents caused by improper adjustment of the spring can be prevented.
  • the feature of claim 8 enables a full support of the two collar halves on the one hand in the middle position and on the other hand in each of the two end positions of the swung out sole plate.
  • claim 9 reduces the length of the release lever and the force required to open the heel holder.
  • the measure of claim 10 also aims in this direction.
  • the feature of claim 11 enables a reliable opening of the heel holder even if it does not automatically jump into the starting position as a result of wear and tear in the event of an arbitrary release after the release point has been exceeded.
  • the heel holder can be brought directly into its closed position by actuating the release lever counter-clockwise.
  • Figure 1 is a side view of the entire safety ski binding.
  • 2 is a vertical longitudinal central section through the heel holder of the safety ski binding according to the first embodiment, which is in the driving position.
  • Figure 3 is a section along the line III-III in Figure 2 and
  • Figure 4 is a vertical longitudinal central section through the release lever of the heel holder.
  • FIGS. 5-7 show in the longitudinal middle section of the sole holder the interaction of the sole holder and release lever during the arbitrary opening process in a plane lying behind, further components being only indicated.
  • 8 shows a second embodiment of a heel holder, which is also in the driving position, in the vertical longitudinal central section.
  • the safety ski binding shown in Fig. 1 to 7 is a so-called plate binding.
  • a sole plate 1 is pivotally mounted around the pivot 2b in a horizontal plane.
  • a front jaw 2c is attached, which is not the subject of the present invention.
  • the rear end of the sole plate 1 carries a heel holder, designated in its entirety by 3, which has a housing 6.
  • a body 4 On the base plate 2a, a body 4 is also attached, which carries on its side facing away from the pivot 2b a top view of approximately V-shaped control cam 4a on which a roller 7 is guided.
  • a circular arc-shaped groove 5 is recessed, in which a rib 1a of the sole plate 1 engages.
  • a fork 8 which is also screwed to the soleplate 1, is fastened to the housing 6 of the heel holder 3 on the side facing the pivot 2b by means of a rivet 8a.
  • the fork 8 forms a bearing block.
  • two recesses 9a and 9b are recessed in the housing 6, which serve to receive a compression spring 12 and two compression springs 13.
  • the compression spring 12 acts on a piston 10 which is guided in the recess 9a formed as a bore.
  • a unit consisting of a sole holder 15 and a step spur 16 is articulated to this, on the inside of which there is a control cam 17.
  • the transverse axis 14 also carries a control lever 20, on the lower end of which the axis 20a for the roller 7 is mounted.
  • the control lever 20 is approximately frame-shaped with a recess 21, the latter serving for the passage of the nose 10a of the piston 10. This is pressed by the compression spring 12 against the rear boundary surface of a locking rocker 23, the axis 24 of which is mounted in the fork 8 and the front side of which rests on the control cam 17.
  • two bores 20b are provided in the control lever 20, into each of which a shoulder 11b of the heads 11a of each tappet 11 engages.
  • the release lever 18 is approximately U-shaped in front view and has hook-like projections 18a in the region of its two legs, which are in operative connection with the lower guide surfaces 15b of the sole holder 15. Furthermore, the trigger lever 18 has two on its two legs to the outside showing lateral approaches 18b, which interact with congruent surfaces 15a of the sole holder 15 when opening after the trigger point has been exceeded. Finally, in the upper region of the two legs of the release lever 18, two lugs 18c are provided, which are assigned to upper guide surfaces 15c of the sole holder 15 and which serve to close the sole holder 15.
  • the lugs 18c are also supported in the closed state of the binding on the sole holder 15 and thus stabilize the position of the release lever 18 (FIG. 5).
  • a recess 18d is formed in the central region, which serves to release the transverse axis 14.
  • the web 18e of the release lever 18 carries an indentation 18f which is intended to engage the tip of a ski pole.
  • 18g denotes the bores in the legs of the release lever 18, which are penetrated by the axis 31.
  • the two plungers 11 are located in the recess 9b and are pressed by the two compression springs 13 against the control lever 20.
  • the trigger lever 18 is pivoted clockwise.
  • the phases of the opening are shown in Figs. 5-7.
  • the extensions 18a of the release lever 18 engage the lower guide surfaces 15b of the sole holder 15 and which lie laterally from the longitudinal center plane and pry up the sole holder 15, the end of the locking rocker 23 sliding along the control curve 17, which compresses the compression spring 12 Consequence (Fig. 5).
  • the sole holder 15 opens, supported by the relaxing compression spring 12.
  • the opening of the sole holder 15 is additionally supported from a certain opening angle in that the shoulders 18b of the trigger lever 18 on the congruent surfaces 15a of the sole holder 15 come to rest.
  • the release lever 18 shown in FIG. 4 is not limited in its application to the embodiment shown in FIG. 2, it can also be used in the embodiment according to FIG.
  • FIG. 8 The embodiment of a heel holder 3 'shown in FIG. 8 is similar to that described first. In this embodiment, however, only two compression springs 12 'and 13' are connected coaxially to one another.
  • the inner compression spring 13 ' is supported by means of a spring plate 24'a and Collar (25'b) from an adjusting screw 25 'on the somewhat angled control lever 20', which is provided with a passage opening 22 for the centering screw 25 'and which is articulated on the housing 6' by means of the transverse axis 14 'and carries the roller 7'.
  • the outer compression spring 12 ' is supported by a pressure ring 26 on a fork-shaped intermediate member 19 which is approximately triangular in side view, is articulated on the transverse axis 14', carries a further roller 27 and laterally surrounds the control lever 20 '.
  • the further roller 27 rolls on the locking rocker 23 ', in the upper region of which an axis 31' is arranged, on which the release lever 18 is mounted.
  • 23'a designates the nose of the locking rocker 23 'with which it rests on the control cam 17'.
  • the adjusting screw 25 ' is extended towards the end of the ski.
  • This extension 25'a is guided in a sleeve 28 which carries an external thread and is mounted in the rear wall of the housing 6 '.
  • a spring plate 29 is screwed onto the sleeve 28. Between the spring plate 29 and the compression spring 12 'there is a pressure ring 30 which bears a mark 30a. The position of this mark 30a and thus the pretension of the compression spring 12 'can be read from a window 6'a in the housing 6', which is provided with a scale.
