Definitions

  • ABSTRACT An apparatus for releasing a safety ski binding comprising an actuation element intended to bear against the shank of the leg above the ankle bone.
  • This actuation element may be operatively coupled directly or indirectly with an automatic release mechanism of the ski binding so that the latter is released through pronounced bending of the leg shank relative to the ski.
  • the actuation element may be constituted as part of a ski boot or as a separate component.
  • the present invention relates to a new and improved apparatus for releasing a safety ski binding.
  • Still a further significant object of the present invention relates to an improved construction of apparatus for effectively releasing a safety ski binding in a quick, positive and reliable manner and which is relatively simple in construction, economical to manufacture, and extremely easy to use.
  • Yet another object of importance relates to the provision of an apparatus for effectively releasing a safety ski binding which may be integrated as a component of the ski boot or constitutes a separate component which cooperates with the ski boot.
  • the invention contemplates the provision of an actuation element intended to bear against the shank of the leg above the ankle bone.
  • This actuation element can be coupled directly or indirectly with the automatic release mechanism of the ski binding, so that upon pronounced bend ing of the lower shank of the leg relative to the ski the automatic release mechanism can be released.
  • FIG. I is a schematic side view of a first embodiment ofinventive apparatus for releasing a safety ski binding:
  • FIG. 2 is a schematic side view of a second embodiment of inventive apparatus:
  • FIG. 3 is a schematic side view of a third embodiment of inventive apparatus:
  • FIG. 4 is a schematic side view of a fourth embodiment of inventive apparatus.
  • FIG. I there is shown a ski boot B having a lower boot portion 1 equipped with a sole 2 and an upper portion 3, secured through the agency of any suitable closure mechanism 4 to the shin bone or shank of the leg of a skier.
  • the boot upper portion 3 is pivotably connected at hinge location 5 at the region ofthe ankle joint with the lower portion I of the ski boot.
  • Upper portion 3 possesses at its rear region a downwardly depending extension 6 provided with a projection or nose 7 capable of operatively engaging with a standard safety ski binding, generally indicated by reference character R.
  • projection 7 engages with a part 8 of a heel support 9 of such schematically illustrated ski binding.
  • the boot upper portion 3 supported via the ski boot B indirectly at the ski S is pivoted or rocked about the hinge joint 5 so that the projection or nose 7 is raised.
  • the safety ski binding R is released.
  • the upper portion 3 and the extension 6 equipped with the projection 7 or equivalent structure thus form an actuation element functioning in the manner of a double-arm lever wherein one arm of such double-arm lever i.e. here the upper portion 3 is substantially coextensive with the lower shank of the leg.
  • FIG. 2 there is shown a ski boot upper portion 10 which likewise can be fixed by means of a suitable closure mechanism 4 with the leg shank or shin bone.
  • Upper portion 10 is here downwardly extended and hingedly connected at the hinge joint means 11 with the sole 2 of the ski boot B.
  • a similar hinge joint would be advantageously provided at the opposite side of the boot.
  • a projection 12 at the rear lower end of the upper portion 10 cooperates with a part of portion 13 of the ski binding R, here for in stance an automatic heel release mechanism 14 of such safety ski binding, so that during an extreme bending or flexing of the leg shank or shin-bone during a frontal fall the ski binding R will be released in the same manner as considered above for the first embodiment.
  • the upper portion 10 together with the projection 12 functions, as previously explained, in the manner of a double-arm lever which is indirectly supported at the ski S through the agency of the ski boot sole 2.
  • the embodiment of ski boot depicted in FIG. 3 likewise possesses an upper portion 15 hingedly connected at the hinge joints or pivot means 16 with the boot sole 2 and which can be connected about the shin bone or shank of the leg through the agency of the closure mechanism 4 or equivalent.
  • the upper portion 15 extends to the region of the top surface or face of the ski S and possesses two contact or impact points or regions P and P which during rocking of such boot upper portion 15 about pivot means 16 cooperate with the top surface of the ski.
  • the portion 17 of the heel support 18 of the safety ski binding R engages over the heel region of the ski boot B, so that upon lifting such ski boot heel the safety ski binding will be released.
  • the upper portion thus provides an actuation elenent in the form of a double-arm lever which is indiectly supported at the ski via the ski boot sole 2 and s indirectly coupled with the automatic heel release nechanism of the ski binding R via the heel of the ski not B.
  • ski boot upper portion 19 vhich again can be fixed about the shin-bone or shank )f the leg of the skier through the agency of the closure nechanism 4 or equivalent.
  • This ski boot upper portion [9 possesses a part or component 20 defining for in .tance at least one but preferably two flexed portions vhich extend beneath the sole 2 of the bottom portion l of the ski boot B and rest in at least one, but preferaily two recesses 21 provided at opposite sides of the met sole 2 at the region of the top surface of the ski 3.
  • a part 22 of the heel support 23 of the ski minding R engages over the heel of the ski boot.
  • the upper portion 19 will )e correspondingly pivoted and component 20 in coop- :ration with the recesses 21 and the top surface of the ki S raises the rear part of the ski boot B away from uch top surface of the ski so that in the same manner is for the embodiment of FIG. 3 here also the safety ski iinding R is released. Also in the case ofa rearward fall he rear end of the ski boot will be raised in the same nanner and the ski binding released. in this case the acuation element defined by the upper portion 19 and .lso forming a double-arm lever, as previously exllained. is directly supported at the ski and indirectly oupled via the heel with the automatic heel release nechanism of the ski binding.
  • Such type actuation elenent can be constructed as a unit which is independent f or separate from the ski boot.
  • the upper portion an form the actual upper of the ski boot or, for intance, can constitute an additional sleeve or collar.
  • An apparatus for releasing a safety ski binding comprising actuation means adapted to be affixed to the lower shank of the leg above the ankle joint in cooperating relation with a ski boot, said actuation means further adapted to be operatively connected to an automatic release mechanism of a safety ski binding for releasing said automatic release mechanism upon pronounced bending of the lower shank of the leg relative to the ski, said actuation means comprising a doublearm lever and further adapted to be pivotally retained on the ski boot at a location spaced from the point of operative connection of said actuation means with said automatic release mechanism.
  • said actuation means includes means for facilitating direct connection of said actuation means to said automatic release mechanism of the ski binding.
  • said actuation means includes means for facilitating indirect connection of said actuation means to said automatic release mechanism of the ski binding.
  • actuation means includes means for directly supporting said actuation means on the ski.
  • said actuation means includes a member substantially comparable to at least part of the upper portion of the ski boot, said member adapted to encircle the lower shank of the leg above the ankle joint.
  • said actuation means is a unit adapted to be operably connected to the ski boot.
  • said actuation means includes projection means for engaging a release element of an automatic heel release ski binding.
  • An apparatus for releasing a safety ski binding comprising an actuation element intended to be fixed with the lower shank of the leg above the ankle joint and capable of being connected with an automatic release mechanism of a safety ski binding, so that said automatic release mechanism will be released upon pronounced bending of the lower shank of the leg relative to the ski, and means for articulating said actuation element to the lower portion of a ski boot, said actuation element including a projection intended to engage with a release element of an automatic heel release ski bind- 20.
  • An apparatus for releasing a safety ski binding comprising actuation means adapted to be pivotally mounted to a ski boot for acting upon a releasable ski binding such that during undesired positional shifting or loading of said actuation means the releasable ski binding will be actuated to assume a ski boot release position, said actuation means including a portion extending essentially coextensive with the lower shank of the skiers leg when inserted into the ski boot.
