Definitions

  • the present invention relates to a new and improved construction of releasable ski binding of the type incorporating a release plate releasably anchored at both of its ends to the ski against the action of spring force, the release plate being equipped with holding means for the heel and sole of the ski boot.
  • Another and more specific object of the present invention relates to a new and improved construction of releasable ski binding incorporating a release plate and means providing for selective support action of the ski boot such that the inclination of the boot can be varied, as desired, with respect to the ski.
  • the releasable ski binding of this development comprises a release plate equipped with means providing a support which can be adjusted to all sides for the ski boot with respect to its inclination relative to the ski.
  • the release plate further is equipped with adjustable holding means for the heel and sole of the boot.
  • release plate permits adjusting to all sides the angle of inclination of the boot with respect to the ski, so as to be able to undertake corrections for the skier if, for instance, the skier has bowed legs (O-shaped legs) or else so-called X-shaped legs or to be able to allow the skier to adjust the release binding so that he can ski with a particular individual style or at least try out such style.
  • adjustable holding means for the heel or sole of the ski boot can be advantageously constituted by a respective bracket; the ends of each bracket are anchored at the release plate and the length between the anchoring locations can be adjusted.
  • a further advantageous construction of the invention contemplates that the anchoring means of the brackets are adjustable not only in the lengthwise direction of the release plate but also in a direction transversely with respect thereto.
  • the support means adjustable in inclination and the appropriately adjustable heeland/or sole holding means a particularly beneficial symbiosis insofar as the holding means not only permit of every random inclination, but furthermore at the same time also allow for a random shifting of the supporting or tread surface of the ski boot and therefore a complete individual accommodation of the relationship between the skier and the skiis.
  • the ski boot can be inclined towards the one and/or the other side to a greater or lesser extent, as desired, and thus can be randomly shifted in the lengthwise direction of the ski, but also can be shifted or positioned laterally forwardly and/or rearwardly and also at an inclination.
  • the adjustability of the ski boot relative to the ski exceeds these adjustment possibilities which can be realized with a universal joint.
  • FIG. I is a top plan view of a releasable ski binding incorporating a release plate, the adjustable support means of which are provided by support screws, wherein however the support screws have been conve' niently shown in the disassembled position at the lower part of this FIG. 1;
  • FIG. 2 illustrates the arrangement of FIG. I viewed from the side, further depicting a ski boot mounted in the releasable ski binding and the holding means engaging with the heel and the sole of such ski boot;
  • FIG. 3 is a variant construction of releasable ski binding, depicted similar to the showing of FIG. 1, but in this case employing as the support means wedge-like members;
  • FIGS. 4 and 5 illustrate further modified constructions of the wedge-like members.
  • FIGS. 1 and 2 there is shown a releasable ski binding of the type incorporating a release plate 2 re leasably retained to be movable to all sides at the ski 1, by means of anchoring pins 3 and 4 engaging with the opposed ends 2a and 2b respectively, of the release plate 2, as best seen by referring to FIG. I.
  • the anchoring pins 3 and 4 sometimes also known as locking pins, are pivotably mounted for movement to all sides in their associated housing 5 and 6 respectively.
  • Each such anchoring pin 3 and 4 is subjected to the action of a non-visible spring arranged in its respective housing 5 and 6, so that these anchoring pins normally assume the position depicted in FIGS. 1 and 2, and thus retain the release plate 2 in its illustrated normal position on the ski 1. Furthermore as far as the locking pin 3 is concerned, which is here shown mounted at the rear end 2a of the release plate 2 considered with respect to the ski boot 10, this pin 3 cooperates with the release plate so as to also retain such against lateral movement until exceeding the permissible safety factor of setting of the binding.
  • the position of the release plate 2 is fixed by a pivot or plug pin 7 which fits into a bore 2c of the release plate 2 and in cooperation with such release plate 2 provides a plug-like releasable connection for the release plate at the ski I.
  • the pivot pin 7 and bore 20 may be each advantageously of cylindrical shape.
  • the release plate 2 can pivot about the pivot pin 7 and in the case of a load acting in the lengthwise direction of the ski also can raise away from such pivot pin 7 which is normally fixed to the top surface of the ski.
  • the release plate 2 is provided at both of its ends 2a and 2b as well as at its central region 2d with respective pairs of threaded recesses or bores 8 serving to receive support screws 9.
  • These support screws 9 in their entirety form support means for the ski boot it], the heel and sole of which bear upon the convex-shaped screw heads 90. Consequently, it should be apparent that the ski boot I can be spatially positioned, e.g. tilted and/or canted as desired, to impart thereto a given desired inclination.
  • the heel and sole tip of the ski boot it are each connected via a holding member, here in the form of a respective bracket 11 and 12, with the release plate 2, and thus the boot can be securely urged against the support screws 9.
  • a holding member here in the form of a respective bracket 11 and 12, with the release plate 2, and thus the boot can be securely urged against the support screws 9.
  • the threaded anchoring spindles l3 and the threaded spindle sleeves or threaded nut members 14 in each case arranged at the ends of the associated bracket 11 and 12, it is possible to vary the length of such brackets in order to ensure for positive retention of the ski boot for any inclination thereof which it might assume.
  • the spindles l3 selectively engage by means of their inwardly flexed threaded ends into one of the lateral threaded recesses or bores provided in spaced relationship along the lengthwise extending edges of the release plate 2, as best seen by referring to FIG. 2. Owing to this construction the spindles 13 can be adjusted transversely with respect to the release plate 2, wherein, on the one hand, it is possible to vary the mutual spacing of the anchoring means and, on the other hand, the brackets themselves can be displaced laterally with respect to the release plate 2.
  • the screws 9 can be formed of plastic or the like or could possess a covering or coating formed of such material; instead of using screws with slotted heads they could also have hexagonal heads or the like, so as to be able to rotate such screws even when the ski boot is mounted on the release plate. They could also possess large surface heads or be combined in groups or in totality with a respective support element, for instance a fiat or plate-shaped support element. Instead of using the screws it would be also possible to use other suitable support elements which can be adjusted in height or mutually exchangable support elements possessing different heights, such as wedges, double'wedges, shims and the like. All such elements in any event will provide a support for the ski boot which allows such boot to be adjusted to all sides with respect to the inclination that the boot assumes relative to the ski.
  • FIG. 3 illustrates such a modified arrangement of releasable ski binding viewed in top plan view, similar to the showing of FIG. 1, wherein alongside of the actual releasable binding there have been shown details of certain of the components.
  • substantially U-shaped wedges 20 and 21 or equivalent structure which are mounted for instance in straddling relationship on the release plate 2.
  • a releasable ski binding for use with a ski and a ski boot having a heel, sole and bottom tread comprising a release plate, anchoring means for releasably anchoring the release plate at its ends to the ski, support means for the ski boot provided on the top surface of the release plate acting against the bottom tread of the ski boot for enabling adjustment of the inclination of the ski boot relative to the ski in the lengthwise direction of the ski and canting of the ski boot relative to the ski in the transverse direction of the ski, and adjustable holding means for the heel and sole of the ski boot mounted on said release plate for adapting the holding means to the assumed inclination and canting of the ski boot brought about by the action of the support means.
  • support elements comprise wedge means.
