Definitions

  • the present invention relates to a ski boot according to the preamble of claim 1.
  • Alpine skis are usually equipped with safety bindings that consist of a front and a rear binding part, as is known, for example, from the standards DIN 7880, 150 5355 and 150 9462. These hold the ski boot releasably fixed in the toe and heel area on the ski.
  • the front binding part usually triggers when turning around an axis perpendicular to the ski surface, while the rear binding part releases the ski boot when falling forward.
  • the problem with turning falls is that the release characteristics of the front binding part can be influenced by undefined and unmanageable frictional relationships between the heel of the ski boot and its base, for example a support plate of the rear binding part or a step plate of a ski brake.
  • the release of the front binding part can be delayed above all if the sole of the heel and the support or tread plate have a profile which are locked into one another in the idle state or can lock into one another during the release of the binding.
  • a good profile of the sole, especially in the heel area, cannot be avoided to ensure safe walking with the ski boots.
  • the rear binding part presses the ski boot against the surface in the heel area with considerable force. This fact, even with negligible profiling of the sole and base, means that the heel turns requires a considerable amount of effort as long as the shoe is still held in the binding at the bottom.
  • the CH-PS 522 371 discloses a sports shoe for football, hockey, golf or tennis, or for ballroom dancing with a sole and / or heel part which is rotatable relative to the rest of the shoe about an axis which is substantially vertical runs to the sole or heel.
  • the sole or heel part enables the person wearing the shoe to rotate about an axis and is thereby protected against sliding.
  • the object of the present invention is to create a ski boot in which the frictional relationships between the heel and its base have no influence on the functional reliability of the ski binding, in particular in the event of a turning crash.
  • the heel element is mounted in a heel piece and projects downwards above it.
  • the heel element can be kept small and the heel piece can be equipped with a good profile, so that safe walking is possible.
  • the heel element is plate-shaped and can be fastened to the heel piece by means of a snap connection. This allows a simple and safe assembly of the heel element and a problem-free replacement of the same.
  • the heel element and the heel piece preferably have annular or circular opposing sliding surfaces which lie essentially in planes perpendicular to the axis. As a result, the friction can be kept small and a rocking of the heel element against the heel piece can be prevented.
  • the shaft 10 of the ski boot 12 shown in FIG. 1 consists of a front and a rear shell part 14 and 16.
  • the front shell part 14 covers the foot of the wearer in the toe and instep area and the lower front part of the lower leg, with a transverse ribbing 18 between the instep and the lower leg allowed after bending the lower leg of the wearer forward.
  • the rear shell part 16 comprising the rear lower part of the lower leg is pivotably mounted on the front shell part 14 by means of a joint 20.
  • the two shell parts 14 and 16 which are preferably made of plastic, are held together with a closure, not shown.
  • a padded inner shoe 22 Arranged in the interior of the shaft 10 is a padded inner shoe 22 which projects above the two shell parts 14, 16.
  • a sole 24 of the ski boot 12 is held in the front end region by a front and in the heel region by a rear binding part 26 or 28 fastened to a ski 25.
  • the sole surface 30 rests in the toe area on a support plate 32 of the front binding part 26, while a heel element 34 arranged in the heel area 33 is supported on a step plate 36 of a brake 38.
  • the brake 38 is held by the shoulder element 34 in the position shown in FIG. 1.
  • the spring-loaded and pivotable brake 38 pivoted on the ski surface 39 swivels clockwise by approximately 90 °, so that lateral brake hooks 40 slide over the sliding surface 42 of the Skis 25 protrude and prevent an uncontrolled descent of the skis 25.
  • FIG. 2 the parts specified further above are designated with the same reference numerals as in FIG. 1. These parts are only dealt with to the extent that this is necessary for an understanding of the invention.
  • Solid lines show the ski boot 12 in its normal position as it is held on the ski 25 by means of the front and rear binding parts 26, 28.
  • the rear binding part 28 triggers and pivots about an axis parallel to the ski surface 39 and perpendicular to the longitudinal axis 44 of the ski and thus releases the heel area 33 of the ski boot 12 so that it can separate from the ski 25.
  • the front binding part 26 In the event of a fall, however, the front binding part 26 must also release the ski boot 12.
  • the front binding part 26 can be pivoted about a pivot axis 46, which runs perpendicular to the ski surface 39 (cf. also FIG. 1).
  • the ski boot 12 is shown in broken lines during the release by the front binding part 26.
  • Its longitudinal axis 48 has pivoted by an angle ⁇ relative to the longitudinal axis 44 of the ski around a further axis 50 (see FIG. 1), which runs perpendicular to the sole surface 30 and is located in the heel area 33 of the sole 24.
  • the ski boot 12 rotates about this axis 50, because during the release of the ski boot 12 from the rear binding part 28, the tread plate 36 of the brake 38 follows the heel element 34.
  • FIG. 3 shows the heel area 33 of the ski boot 12 with a part of the rear binding part 28 and the ski 25 cut along a line III-III of FIG. 4.
  • a heel piece 54 is attached to a sole wall 51 by means of four screw bolts 52.
  • the heel piece 54 is covered on the underside by a herringbone profiled sole part 56, the rear end of which is supplemented by an exchangeable rubber part 58.
  • the heel piece 54 has a stepped recess 60 which is central to the axis 50 and has an annular rib 61 which is delimited in the radial direction towards the bottom by a sliding surface 62 perpendicular to the axis 50 and at the top by a snap surface 64 parallel thereto.
  • An element body 66 of the shoulder element 34 is rotatably mounted on the rib 61.
  • the element body 66 is plate-shaped and has a concentric ring of snap tongues 68, the snap lugs 70 of which engage behind the snap surface 64.
  • the element body 66 has a further annular sliding surface 72 which is parallel to the sliding surface 62 of the heel piece 54.
  • the underside 74 of the element body 66 is provided with a profiled step covering 76 made of a soft plastic.
  • the compressive strength of the step covering 76 is lower than that of the element body 66, which is designed as a supporting element.
  • the tread covering 76 rests on the tread plate 36 of the brake 38 and projects downward over the sole part 56.
  • the tread plate 36 is made of plastic and is provided with holes 78 which form a profile.
  • the pivot shaft of the brake 38 is designated 80.
  • the sliding surface 42 is the surface of a ski base 82.
  • the frictional relationships between the tread plate 36 of the brake 38 and the sole 24 of the ski boot 12 no longer play a role in the triggering of the front binding part 26 in the event of a turning or forward turning fall.
  • the heel element 34 is rotatably mounted in the heel piece 54 so that it can maintain the position relative to the tread plate 36 while the remaining part of the ski boot 12 swivels about the axis 50; the sliding surfaces 62, 72 and the ring 73 limit the friction to a very low degree.
  • the ski 25 is not equipped with a brake 38, there is a rear support plate on the step plate 36, on which the heel element 34 comes to rest. In this case, too, the frictional relationships between this support plate and the heel element 34 do not play a role in the release of the front binding part 26.
  • the step covering 76 can be equipped with a profile, which is formed, for example, by irregularly distributed knobs.
  • the heel piece 54 Since the heel piece 54 is screwed to the sole wall 51, it can be exchanged without problems together with the heel element 34, if this is necessary, for example, as a result of wear on the sole part 56 or the step covering 76.
  • a sole exchange of the heel element is also possible by detaching the snap lugs 70 from the snap surface 64 and removing the heel element 34 from the heel piece 54 and a new heel element 34 is inserted into the recess 60 and attached to the snap surfaces 64.
  • rollers or balls can also be arranged between the sliding surfaces 62 and 72. These friction-reducing means can be dispensed with if the heel piece 54 and the heel element 34, at least in the area of the sliding surfaces 62, 72, consist of materials which have a small amount of friction in the common contact surface.
  • the heel element 34 and / or the heel piece 54 can be composite injection molded parts, the element body 66 and the heel piece 54 being made of plastic and having an anti-abrasive surface on the underside, the compressive strength of which is lower than that of the heel piece 54 and the element body 66.
  • the rotatable heel element 34 is formed by the entire heel area 33.
