Definitions

  • This invention concerns an element to distribute forces on ski boots, as set forth in the main claim.
  • the distributor element according to the invention is applied to the field of footwear and, in particular, to the manufacture of ski boots for downhill skiing which have their leg portion fitted so as to be able to oscillate backwards and forwards on the upper of the boot.
  • the thrust of the skier in these particular operations has possibly to be discharged without dispersions along a well defined part of the ski so as to enable the ski to be correctly controlled.
  • the difficulty lies in discharging the forces imparted by the leg directly onto the sole of the boot and especially onto the desired side of the boot so as to ensure a good thrust against the ground and therefore a correct control and a good anchorage of the skis on the snow.
  • the boots tend to be deformed resiliently and to bulge under the effect of the thrust of the leg of the user, this thrust being discharged onto the leg portion of the boot, while the undesired deformation causes a marked dispersion of the thrust, which therefore is not discharged downwards.
  • Some devices disclosed are applied to the outside of the boot and provide for the use of a plurality of elements which are associated with each other, with the upper and with the leg portion of the ski boot.
  • WO 92/16120 discloses a ski boot including a support which cooperates at the rear with the leg portion associated with the calf of the skier and below with the sole of the boot by means of a bar; this support has a form mating with the leg portion with which it cooperates partly at the rear, and is fixed to the upper by a fork element which cooperates substantially with half of the circumference of the leg.
  • This device generates torques, which act on the boot and tend to open out the path of the ski in a curve or else cause a rotation of the boot around itself under certain extreme conditions.
  • EP-A-0.430.821 discloses a ski boot in which a symmetrical fork cooperates at the rear with the high part of the leg portion of the ski boot and is pivoted below on both sides of the upper of the boot.
  • This device makes possible a symmetrical discharge of the thrust exerted by the skier on the leg portion of the boot but does not make possible the directing of this thrust onto the desired part of the ski, as required during changes of direction and halting.
  • EP-A-0.634.115 discloses a ski boot having a lateral support comprising at least one rigid element, which is a one-piece element or is conformed as an integral part of the upper of the boot; this element is associated at least partly with the inner side of the foot, of the leg and of the instep.
  • This lateral support transmits to the base of the boot and to the instep thereof the lateral thrust provided by the calf of the leg, this transmission being direct and affecting only partially the boot.
  • this transmission discharges the lateral thrust onto a plane perpendicular to the base of the boot.
  • the purpose of this invention is to provide a ski boot comprising an element to distribute the forces, this element enabling all the force imparted by the leg to be discharged substantially directly on the boot and at the desired zone of the sole of the boot so as to make possible a correct control of the ski.
  • the distributor element according to the invention enables that thrust to be discharged substantially wholly along the desired part of the boot, thus facilitating control of the ski especially during changes of direction.
  • the distributor element according to the invention ensures a working elasticity, which makes the bending of the leg progressive and at the same time assists return of the leg to the unbent position.
  • the distributor element according to the invention includes an upper part which is associated with the upper rear part of the leg portion of the boot and which surrounds partially that part and the lower part extending on the desired side of the boot.
  • the lower part of the element distributing the forces extends at its lower end to the desired zone of the boot.
  • the lower part of the distributor element is firmly associated with the leg portion of the boot and with the rear portion of the upper.
  • lower part of the distributor element is anchored laterally to the upper at both the front and rear ends of the upper.
  • the distributor element according to the invention is simple to produce and install.
  • the inclusion of the distributor element on the rear part of the boot makes possible the opening of the upper at the front in the area of the neck of the foot and thus improves the fitting of the boot.
  • the distributor element according to the invention is asymmetrical and entails a thrust towards the inside of the boot, which assists transfer of the thrust to the inner edge of the ski..
  • the distributor element may consist of two pieces following each other in the longitudinal direction and stably associated with each other so as to permit personalised adjustments.
  • the distributor element includes means for the stable connection/momentary disconnection between its upper part and the upper rear part of the leg portion of the boot so as to facilitate walking around.
  • the lower rear lateral part of the element is associated with slit means and clamping means to enable the distributor element to oscillate together with the leg portion of the boot.
  • the lower front lateral part of the element is associated with a pivot for rotation of the leg portion of the boot.
  • the distributor element according to the invention may include thinned areas to reduce the weight and to control the axis of transmission and distribution of the thrust according to desired and particular directions.
  • the reference number 10 in the figures denotes generally an element to distribute forces according to the invention.
  • the distributor element 10 according to the invention is applied to ski boots 11 which are used for downhill skiing and which are of a type that comprises an upper 15 with which is associated a leg portion 12 able to oscillate in this case forwards and backwards in relation to the upper 15.
  • leg portion 12 is associated with the upper 15 by means of lateral rotation pivots 13.
  • the distributor element 10 consists of an asymmetric plate, which consists advantageously, but not necessarily, of a plastic material and which includes a first upper part 10a cooperating at least momentarily with the central rear part of the leg portion 12 and a second lower part 10b associated with a desired lower lateral part of the boot 11.
  • the lower part 10b of the distributor element 10 is associated with the inner lateral part of the boot 11.
  • the upper part 10a of the distributor element 10 is secured by first fixture means 16 to the upper rear part of the leg portion 12.
  • the lower part 10b comprises a lower front part 10c associated with the leg portion 12 by means of the rotation pivot 13 of the leg portion 12 and comprises also a lower rear part 10d associated with the lateral rear part of the upper 15 by means of second fixture means 14.
  • the lower rear lateral part 10d is associated with slit means and clamping means to enable the distributor element 10 to oscillate together with the leg portion 12.
  • the lower front part 10c is associated with the lower lateral median part of the upper 15.
  • the lower front part 10c of the distributor element 10 extends so as to be anchored to the lower lateral front part of the upper 15 by means of third fixture means 20.
  • the distributor element 10 consists of a plate consisting advantageously of a plastic material formed in one body.
  • the distributor element 10 consists of two pieces 110, 210 which follow each other and are stably associated together by adjustment and clamping means 19.
  • first fixture means 16 to fix the first upper part 10a of the distributor element 10 to the upper rear part of the leg portion 12 can be momentarily disactuated so as to enable the skier to walk about more easily.
  • the distributor element 10 includes thinned areas 17 which provide the distributor element 10 with the desired characteristics of lightness.
  • the distributor element 10 includes suitably arranged reinforcing ribs 18 to ensure the desired characteristics of stiffness and to ensure at the same time a differentiated transmission of the thrust generated by the leg portion 12 against the desired part of the boot 10 so as to facilitate control of the ski.
