Definitions

  • the invention relates to a side-releasable front jaw of a safety ski binding according to the preamble of patent claim 1.
  • the side-releasable jaws are provided with tilting surfaces arranged on both sides of the vertical median longitudinal plane on the side of the binding housing facing the ski boot, with straight upright, parallel to each other, straight tilting axes, whereby on attack the tilting surfaces under the action of the release force on the side of the sole holder facing away from the ski boot, complementary tilting counter surfaces such that, in the event of excessive lateral forces on the ski boot, the sole holder swings out against the force of the release spring and releases the ski boot.
  • the invention provides according to the older proposal that the release spring exerts a slightly obliquely downward force on the sole holder and between the line of action of the release spring and the branch below it each tilt axis a trained so much less than 90 ° There is an angle that the force component acting downward on the sole holder is able to move the sole holder downward at least in the event of the vibrations occurring during skiing until the hold-down device is pressed against the top of the sole of the ski boot along the tilt axes.
  • the present invention applies the inventive idea according to the older proposal to side-releasable cheeks according to EP-A-0 241 360, in which the side legs swing out laterally about a substantially upright pivot axis when a predetermined side force exerted by the ski boot is exceeded and release the ski boot.
  • the general idea of the invention is to be seen in the fact that the release spring also exerts a downward force component on the hold-down device, which is arranged on the binding housing so as to be vertically tiltable about a transverse axis and is pressed against the top of the ski boot sole by the downward force component.
  • the aim of the present invention is to apply the inventive concept defined above to the side-releasable jaws according to EP-A-0 241 360, without being an exaggerated one Effort for the implementation is necessary and the functional reliability of the baking is impaired.
  • the training according to claim 1 is provided in a side-releasable baking of the type mentioned.
  • a sole hold-down 15 and two side legs 14 are integrally formed on a sole holder 29, the front end of the sole 17 of the ski boot 12 engaging between the side legs 14 provided on the left and right and pressed down by the sole hold-down against a tread plate 41 .
  • the sole holder 29 extends by means of a bridge part 29 'over a central support pin 30 fastened to the ski 22 to the front, where it contains the release spring 13 with an axis arranged in the longitudinal direction of the ski within a release spring receiving space 43.
  • the release spring 13 is on one inside the up receiving space 43 axially displaceably arranged abutment 44 is supported, which can be adjusted in the longitudinal direction of the ski by an adjusting nut 53 accessible from the front, which is screwed onto the front end of a horizontally arranged pull rod 38.
  • the end of the pull rod 38 facing away from the adjusting nut 53 extends through a central opening 54 of the support pin 30 running in the longitudinal direction of the ski with funnel-shaped ends extending somewhat beyond the rear end of the support pin 30, where the end of the pull rod 38 is form-fitting with one perpendicular to the support rod 38 extending, substantially flat support disc 39 is connected, which extends in relation to the axis of the tie rod 38 of this in all radial directions.
  • the flat support disk 39 is preferably arranged round and concentric with the tie rod 38.
  • the tie rod 38 passes through the central bore 54 with clear play on all sides and is in a provided within the central part of the bore 54 ball guide 37, which has a tie rod 38 in the sliding seat receiving central bore 37 ', pivoted in all directions and axially displaceable .
  • the opening 54 has at both ends the funnel shape which can be seen in FIG. 9 and widens outwards. Due to the ball guide 37, the pull rod 38 and thus also the sole holder 29 can be pivoted both about a transverse axis 36 and about a vertical axis 36 '. Combined height-side triggers are also possible.
  • the rear end of the release spring 13 is supported on an abutting abutment 42 on the front support surface 31 of the support pin 30, which abutment 42 is fixed to the bridge part 29 'of the sole holder 29 and preferably forms a piece with it.
  • the sole holder 29 is biased backwards by the release spring 13 and from the rear by the support pin 30, which is arranged ski-supported.
  • the front support surface 31 of the support pin 30 and the rear surface of the abutment 42 fixed to the sole holder and the rear vertical support surface 40 of the support pin 30 and the front surface of the support disc 30 run perpendicular to the pull rod 38, so that the sole holder 39 at predetermined excessive height and / or lateral forces on the tip of the ski boot both in height and in the lateral direction against the force of the spring 13 and can release the ski boot 12.
  • the rear vertical support surface 40 is now above the tie rod 38 - seen in side view - at 40 'by a small angle of e.g. Tilted 5 ° forward.
  • the front surface of the support disk 39 above the tie rod 38 can be tilted somewhat backwards, as is indicated by the dashed line at 39 '.
  • the front support surface 31 of the trunnion 30 below the tie rod 38 - also seen in side view - in the manner indicated at 31 'in dashed lines extend somewhat obliquely downwards and backwards in the direction of the ski boots, while the opposite surface 42' of the abutment 42 correspondingly can be tilted slightly in the opposite direction.
  • the normal height release force becomes effective again, because then both the support plate 39 and the stop abutment 42 again Support radially outwards at the top or bottom on the support pin 30, whereby the resistance to a height movement of the hold-down device 15 is suddenly increased.
  • the sole holder 29 can press onto the ski boot sole 17 from above with a defined force of, for example, 200 N, while above the range of movement a the significantly greater normal height release force acts, which is only overcome under stresses which are dangerous for the skier's leg.
  • the support surfaces extending to the left and right of the pull rod 38 on the support pin 30 or on the support plate 39 and on the abutment 42 are directed flat and perpendicular to the axis of the pull rod 38, so that the lateral triggering by the measures according to the invention for generating a reduced hold-down force is not affected in any way.
  • both the side support and the holding down of the ski boot tip which are arranged obliquely to the longitudinal direction of the ski, can be used, as are provided for the front jaw according to EP-A-0 241 360.
