Definitions

  • the invention relates to a safety ski binding according to the preamble of claim 1.
  • Such a ski binding is essentially described in AT-PS 330.632.
  • the locking member is designed such that it causes the heel holder to be actuated both in the event of excessive lateral forces and in the event of excessive forces occurring in the vertical plane.
  • the toe piece can therefore be designed as a simple holding bracket, as a result of which the holding device for the ski boot can be designed in a particularly simple manner in the front area of the shoe plate.
  • the known device has the disadvantage that the sole plate in the heel area is secured against lifting only by the interaction of the spring-loaded pressure piece with the associated ski-fixed holding part. As a result, changes in the position of the soleplate, which result when the ski bends due to uneven ground, have an effect on the release mechanism of the ski binding.
  • AT-PS 361 350 in which a ski binding is disclosed in which a toe piece is mounted in a longitudinally adjustable manner on a swivel plate with the interposition of a slide.
  • this known solution aims in a different direction than the subject of the invention in that the longitudinal adjustment is only possible to adapt to the shoe size after releasing a locking.
  • the aim of the present invention is to avoid the disadvantages mentioned and to prevent the ski boot or sole plate from becoming tense when the ski is being driven on an uneven terrain.
  • the sole plate is coupled to the guide plate, the sole plate is securely guided in any of its positions, thereby preventing the ski shoe sole located on the sole plate from being braced.
  • both a secure holding of the same and freedom of movement between the sole plate and the ski are guaranteed when the latter bends.
  • the stepless movement of the guide plate on the ski-fixed base plate also serves this purpose.
  • the task is, after a lateral triggering operation, the sole plate both in the front and in the rear area together with the toe and with the heel holder in the starting position, i.e. automatically swing back into the driving position.
  • the features of claim 2 provide a particularly simple but effective design of the movable connection between the sole plate and the guide plate.
  • the toe piece could be mounted directly on the guide plate which is longitudinally displaceable along the guide rail.
  • the bearing block for the toe piece is formed by the front region of the sole plate according to the features of claim 3, whereby the part of the sole plate causing the connection with the guide plate can be formed on the bearing block .
  • the features of claim 4 enable a trouble-free movement with each pivoting movement of the sole plate relative to the guide plate.
  • This feature is additionally ensured in relation to the longitudinal direction of the ski by the features of claim 5.
  • the overall construction thus ensures good and safe ski guidance at all times, even when the ski bends according to the terrain.
  • FIG. 1 shows parts of the ski binding according to the invention in longitudinal section
  • FIG. 2 shows the ski binding according to FIG. 1 with the ski slightly bent, the ski brake being omitted here
  • FIG. 3 shows the front region of the ski binding in longitudinal section on an enlarged scale
  • FIG. 4 shows a section along the line IV-IV of FIG. 3.
  • a complete safety ski binding to be described in more detail on flat terrain can be seen on a ski 1 before boarding.
  • the parts shown with dash-dotted lines are not the subject of the invention and have only been shown for the sake of clarity.
  • a base plate 3 for a toe 10 and a mounting plate 5 for a sole plate 20 pivotally mounted in a known manner on a pivot 6 by means of its recess are fastened by means of only indicated screws 2.
  • the sole plate 20 also carries a heel holder 30 and a ski brake 40, which are of a known type, do not form part of the subject of the invention and therefore have not been described in detail.
  • the pivot 6 is firmly connected to the mounting plate 5 and carries the sole plate 20 with the interposition of a sleeve 7.
  • the sleeve 7 is firmly inserted into the recess of the sole plate 20 in the present exemplary embodiment. It consists of a low-friction plastic material which allows the sole plate 20 to tilt relative to the pivot 6 without the risk of jamming.
  • a polyacetal plastic is particularly suitable as the plastic.
  • the base plate 3 has guide rails 3a which extend in the longitudinal direction of the ski and project upwards on both sides.
  • a guide plate 4 is mounted so as to be longitudinally displaceable but not detachable, side parts 4a of the guide plate 4 embracing or engaging around the guide rails 3a of the base plate 3 (see FIG. 4).
  • a guide groove 4b which runs parallel to the top of the ski and essentially transversely to the longitudinal axis of the ski, is excluded.
  • the guide groove 4b has an upward widening 4b 1 at its front end.
  • the guide groove 4b and its upward extension 4b i run along a circular ring piece, the center line of which is drawn along a circle, the center of which lies at the intersection of the longitudinal axis of the ski 1 and the axis of the pivot pin 6.
  • a downward and rearward sloping guide surface 4c is formed on the top of the guide plate 4.
  • a control nose 4d rises in the region of the longitudinal axis of the guide surface 4c.
  • the front area of the sole plate 20 is designed as a bearing block 20a for the front jaw 10, which is only indicated here.
  • the front end region of the bearing block 20a is designed as an extension 20b with an upwardly projecting part 20c.
  • the projection 20b of the bearing block 20a engages in the guide groove 4b of the guide plate 4, the upwardly projecting part 20c of the projection 20b extending into the extension 4b, the guide groove 4b. There is a slight clearance S between the upward part 20c and the extension 4b.
  • the rear end region of the mounting plate 5 is designed as a guide for the swivel plate 20.
  • An intermediate element 5a and a control cam element 5b arranged above are firmly connected to the mounting plate 5, for example riveted.
  • the front area of the control cam element 5b is designed as a holding rail 5b, and overlaps a holding element 20d which is connected to the sole plate 20 and is approximately U-shaped in cross section.
  • the rear region of the control curve element 5b serves as a control curve 5b 2 for the sole plate 20 and interacts with a control roller 30a connected to the heel holder 30.
  • the control roller 30a is supported by means of its holder 30b on a spring 30c of the heel holder 30 which presses it against the control curve 5b 2 .
  • the guide plate 4 can slide forward on the guide rails 3a of the base plate 3 in accordance with the extent of the ski deflection, the sole plate 20 sliding upwards with its sleeve 7 on the pivot pin 6. This prevents possible tensioning of the sole plate 20 or the deflection of the ski 1 is ensured in accordance with the terrain and thus good and safe ski guidance at all times.
  • a permanent operative connection of the sole plate 20 and the toe plate 10 with the guide plate 4 is ensured at all times, even when the sole plate 20 is pivoted, by ensuring that the L-shaped extension 20b of the sole plate 20 is guided in the guide groove 4b of the guide plate, whereby the upwardly projecting part 20c of the L-shaped projection 20b in the extension 4b, the guide groove 4 engages.
  • the longitudinally displaceable mounting of the guide plate 4 according to the invention in cooperation with a known adjustment mechanism of the sole plate 20, permits a slight length adjustment of the sole plate 20 (approximately in the range of up to three shoe sizes) without the need to reassemble the ski binding, which would weaken the Ski 1 would result from additional holes.
  • the invention is not restricted to the exemplary embodiment shown. There are other variants that fall under the scope of protection.
  • the sleeve can also be attached to the pin.
  • the intermediate plate provided above the mounting plate could also be integrally formed either with the mounting plate and / or with the cam element.
