Definitions

  • the present invention relates to a ski boot comprising an inner comfort liner and auxiliary means for wedging at least a part of the foot, these means being adjustable from the outside.
  • Patent AT-385,185 also proposes to use a screw device directed on the Achilles tendon but acting on tongues by means of two arms. The device occupies a considerable volume in the shoe. The two devices mentioned above do not allow the two sides of the heel to be adjusted differently.
  • the present invention aims to achieve this wedging by means also simple as possible, not very sensitive to frost, continuously adjustable and allowing differentiated adjustment of the two sides of the heel, respectively of the forefoot, when they are present on each side of the shoe.
  • the shoe according to the invention is characterized in that the auxiliary wedging means are constituted by at least one cam rotatably mounted between the shoe and the liner and secured to a pivot passing through the shoe and provided on the outside with a means allowing its rotation training.
  • a shell shoe made of synthetic material and comprising a shell bottom intended to surround the foot and the heel and provided, at the rear, with a relatively flexible tongue extending upwards, and a rod in two parts, of which a rear part is articulated on the bottom of the shell, the cams are mounted on the rear part of the rod and act on the tongue of the bottom of the shell.
  • the drive means consist for example of a screw slot making it possible to drive the cams in rotation by means of a coin.
  • the shoe represented is a shell shoe comprising a shell bottom 1 made of relatively rigid synthetic material surrounding the foot and the heel and a rod articulated on this shell bottom 1, rod comprising a front part 2 and a rear part 3, these two parts being articulated on the bottom of the shell at two opposite points, one of which, 4, is visible in the drawing.
  • This type of shoe, with rear boot, is well known in itself.
  • the rear part 3 of the upper is provided with padding 5 cooperating with an inner liner 6 to ensure the comfort of the foot.
  • the liner 6 is provided at the rear of a pocket 7 in which engages a relatively flexible tongue 8 secured to the bottom of the shell 1 by a narrowed portion 9 allowing the tongue to flex forward and backward and take a more or less pronounced curvature.
  • cams 10 On the rear part 3 of the upper, in two zones located above the heel, on each side of the boot and on either side of the part of the upper intended to come in front of the Achilles tendon of the skier , are arranged two cams 10, one of which is visible in the drawing. The areas of the foot concerned are therefore the areas delimited by the malleoli, the heel and the Achilles tendon.
  • Each cam 10 is integral with a pivot 11 passing through the wall of the rear part 3 of the rod and provided on the outside with a head 12 having a screw slot 13 for its drive by means of a coin or a screwdriver.
  • the cam 10 has a boss 14 extending over approximately half of the disc 15 constituting the base of the cam and centered on the axis of the pivot 11.
  • the cam could however have a different shape. It could for example have the shape of a bell cam as known in mechanics. The main thing is that during the rotation of the cam, the latter gradually pushes inwards the side of the tongue 8 which therefore comes to close on each side of the Achilles tendon. It is thus possible to perfectly wedge the heel.
  • the slight circumferential slope of the cam is sufficient in principle to prevent the reaction of the tongue 8 on the cam causing the latter to rotate.
  • the cams could act directly on the liner or on the padding integral with the rear part of the upper.
  • the cams could be mounted on a bottom of the hull.
  • the cams could be rotated by any means other than a screw slot.
  • the cams can be made of metal or hard plastic.
  • One or two cams similar to the cams described above could also be used to block the forefoot.
  • An example is shown in Figures 4 and 5.
  • the shoe shown is equipped with two cams 16 and 17 mounted on the shell 1, on either side of the median vertical plane of this shell.
  • the cams act on a flexible plate 18 mounted between the shell 1 and the comfort liner 6, which has the function of distributing the pressure of the cams.
  • This plate 18 is constituted either by the extension of a pressure distributor covering the instep for the distribution of the pressure of a cable, or by a particular plate which can be fixed by its end in the region of the end of the foot.
  • the action of the cams 16 and 17 makes it possible not only to wedge the foot in the boot but also to position the axis of the foot optimally for driving the ski.
