Definitions

  • the invention relates to a safety ski binding with a releasable binding part, which holds and triggers the one - in particular front - end of the ski shoe or the ski boot sole as soon as forces acting between the ski shoe or the ski boot sole and the binding part exceed an adjustable triggering force, and with a display on which the set release force can be read.
  • Such safety ski bindings are known in a variety of forms, for example reference is made to DE-GM 74 38 471.
  • the side spacing of sole holders which laterally release the front end of the ski shoe sole can be adapted to the width of the respective sole.
  • the set value of the release force changes. Therefore, according to DE-GM 74 38 471 it is provided that when the distance between the sole holders from one another is adjusted to the width of the ski boot sole, the display of the set triggering force is inevitably changed in accordance with the increase or decrease brought about by the said adjustment. The display shows the actual release force regardless of the set distance between the sole holders.
  • ski shoe soles In today's common ski boots, the ski shoe soles have a standardized width, so that the need to adapt the sole holder or the sole holder to the sole width is largely eliminated. Accordingly, constructions of the type shown in DE-GM 74 38 471 are of little importance.
  • the triggering force is adjusted in accordance with the resilience of the respective skier, in particular in adaptation to the resilience of the knee joints.
  • the value readable on the display of the binding part should reflect the maximum permissible or permitted torque with respect to the axis of the tibia (shin) of the skier. Since on the one hand a torque represents a product of the power and lever arm and on the other hand only the release force can be set directly on the binding part, the display can only correctly reproduce the maximum permissible or permitted torque if the ski boot or the ski boot sole has a specific one Have length or the binding part engages the ski boot or the sole of the boot with a predetermined distance from the axis of the tibia.
  • the ski boots or the ski boot soles have quite different lengths. This means that if the ski binding is set correctly on the display, the Z-value determined for the respective skier cannot usually be shown. Rather, the displayed Z-value will deviate upwards or downwards from the Z-value determined for the respective skier if the binding is correctly set, if the ski boot or the ski boot sole have a particularly large or a particularly small length.
  • the object of the invention is now to provide a safety ski binding, the display of which allows a permissible or permitted triggering torque to be reproduced regardless of the length of the ski boot or the ski boot sole.
  • This object is achieved in that an actuator for shoe length-dependent change of the calibration of the display is arranged on the binding part.
  • a separate display is arranged for the adjustment of the actuator, which shows the length of the ski shoe or the sole of the ski shoe taken into account.
  • the invention is therefore based on the general idea of changing the display depending on the length of the shoe in order to maximize it regardless of the length of the ski boot or the sole of the boot the knees and the like of the skier's torque.
  • the front binding part 1 shown in FIGS. 1 and 2 designed according to the invention, has a housing 2 fastened on the upper side of the ski with two sole holders 3 which cooperate with one another in the manner of pliers and which in a generally known manner, the front end of the ski boot sole, not shown, from above and to the side.
  • the sole holders 3 can trigger according to the arrows P against an adjustable triggering resistance and thus release the ski boot.
  • the triggering resistance is predetermined by the tension of a compression spring 4 which is only visible in FIG. 1 and cooperates with the sole holders 3.
  • This compression spring 4 has an invisible abutment on the sole holder and an abutment 5 on the housing side, which - as shown - can be formed by a flange-like plate against which the compression spring 4 is tensioned at one end.
  • the abutment 5 on the housing side is displaceable within the housing 2 in the longitudinal direction of the ski or in the pressure direction of the compression spring 4, but is non-rotatably guided.
  • a grub screw 6 is non-rotatably fastened, which is screwed into a threaded sleeve 7, which is accommodated within a corresponding bore of the housing 2 and has a flange-like collar 8 on its end facing the housing-side abutment 5, which is supported on a housing-side bearing surface is.
  • a slot 7 ' is arranged in the threaded sleeve 7, into which the blade of a screwdriver can be inserted.
  • the threaded sleeve 7 can be rotated relative to the threaded pin 6 or to the abutment 5 on the housing, the axial distance between the abutment 5 on the housing and the collar 8 of the threaded sleeve 7 being changed accordingly, because the rotation mentioned Threaded sleeve causes a displacement of the threaded pin 6 within the internal thread of the threaded sleeve 7.
  • the tension of the compression spring 4 is changed accordingly, ie a rotation of the threaded sleeve 7 causes a change in the triggering resistance of the sole holder 3.
  • a marking 9 is arranged, which is visible through a slot-like window of a scale carrier 11 arranged on the upper side of the housing and extending in the longitudinal direction of the ski.
  • the scale carrier 11 carries a scale 12 which interacts with the marking 9, on which, in accordance with the respectively set position of the abutment 5 on the housing and thus the marking 9, the respectively set release resistance of the sole holder 3 can be read.
  • the values on the scale 12 are intended to indicate the magnitude of a torque which must be effective with respect to the axis of the tibia (shin) of the skier in order to trigger the sole holder 3.
  • This torque to be released to trigger the sole holder 3 is dependent on the one hand on the tension of the compression spring 4 and on the other hand on the distance of the sole holder 3 from the axis of the tibia or from the length of the ski boot sole.
  • the scale carrier 11 is arranged so as to be displaceable in the longitudinal direction of the ski or in the pressure direction of the compression spring 4, with any positions of the scale carrier 11 being predetermined between two by stops on the housing side by means of an adjusting screw 13 End positions can be set.
  • the set screw 13 is screwed into a threaded bore 14 in the longitudinal direction of the housing or in the pressure direction of the compression spring 4, so that the set screw 13 can be moved forwards or backwards in the longitudinal direction of the ski by rotation in the threaded bore 14.
  • the set screw 13 passes through a bore within an upwardly angled flange 11 ′ of the scale carrier 11, said flange 11 ′ between the head of the set screw 13 and a clamping ring 15, which is fastened to the shaft of the set screw 13, relative to the set screw 13 is held immovable in the longitudinal direction. If the set screw 13 is rotated and pushed forward or backward accordingly in the threaded bore 14 on the housing, the scale carrier 11 therefore undergoes the same displacement relative to the housing 2.
  • a mark 16 is now arranged on the scale carrier 11, which cooperates with a further scale 17 on the housing 2, which in the example shown has graduations for different lengths of the shoe sole (e.g. 250 mm, 300 mm and 350 mm).
  • the triggering resistance of the binding part shown is set as follows:
  • the mark 16 of the scale carrier 11 is turned by a corresponding rotation of the adjusting screw 13 relative to the scale 17 to a graduation line representing the respective length of the ski shoe sole (or to a corresponding intermediate position between two Graduation marks).
  • the scale 12 of the scale carrier 11 is thus calibrated so that, in cooperation with the marking 9, it indicates the value (Z value) of the torque which must be overcome with respect to the axis of the tibia when the sole holder 3 is triggered.
  • the marking 9 of the abutment 5 on the housing can now be adjusted to the value of the scale 12, which corresponds to the maximum tolerable torque with respect to the axis of the tibia of the skier.
  • FIGS. 3 and 4 differs from the embodiment of FIGS. 1 and 2 essentially by a different mounting of the scale carrier 11.
  • the scale carrier 11 has an extension, which is designed as a toothed rack 18 and interacts with a gear 19 that is rotatable in the housing 2 but is mounted with an escapement.
  • a central pin 20 is arranged on the gearwheel 19 in a rotationally fixed manner, which is received in an upwardly open bore in the housing 2 and has a slot 20 'at its upper end for inserting a screwdriver.
  • the gear wheel 19 can be rotated within the housing 2, the scale carrier 11 changing due to the Interaction of the gear 19 with the rack 18 moves accordingly in the longitudinal direction of the ski. Since the gear 19 is arranged within the housing 2 with an escapement, an automatic rotation of the gear 19 and thus an automatic displacement of the scale carrier 11 after an adjustment has been made are prevented.
  • the scale support 11 is transparent, so that the arrangement of a slit-like window 10 (see FIG. 2) in the scale support 11 is unnecessary and the marking 9 on the housing-side abutment 5 (see FIG 1) is visible through the scale carrier 11.
