Definitions

  • the invention relates to a shoe intended to be releasably supported. on a sliding board, and in particular an alpine ski boot. It also concerns a pair of shoes.
  • An alpine ski boot is generally held in abutment against a ski by a front fastener and a rear fastener.
  • Each fastener has a movable retaining jaw against the return force of a spring, in order to release the shoe beyond a determined stress threshold.
  • the tips of the shoe which include the end of the sole and lower part of the upper have a symmetrical shape with respect to a plane vertical and longitudinal.
  • This thus defined shape can be associated with different models of fasteners. In addition, it can be indifferently associated with one or the other of the two skis of a pair.
  • the stress threshold beyond which the binding element releases the shoe is the same that the torsional stress tends to make the shoe come out towards the inside of the foot or towards outside.
  • the knee of a human being is more or less resistant to torsional stress exerted on the leg, in the direction of the latter.
  • the knee is more fragile for an inward rotation of the foot, that is to say towards the other foot.
  • the problem posed by the invention is to propose a shoe which improves the knee protection.
  • Another object of the invention is to provide a shoe which remains compatible with the market fasteners, just like a standard shoe.
  • Another object of the invention is to propose a shoe which is simple to produce.
  • the shoe is made more easily releasable on one side than on the other.
  • the shoe escapes the element of fixing more easily in one direction of loading than in the other. This first sense advantageously corresponds to the direction where the skier's knee is the most fragile.
  • the shape of the end piece is adapted front of the shoe to make the shoe more easily releasable on one side.
  • the friction between part of the end piece and the fixing element is provided.
  • Figures 1 and 2 illustrate the state of the art and show a shoe 1 with a sole 2 as defined by standard ISO 5355.
  • the sole 2 has in particular a front end piece 3 and a rear end piece 4.
  • the front end piece 3 which is more particularly concerned with the invention comprises a lower part of sole delimited by a sole surface 5 and an upper part of upper defined by an upper surface 6 located on the upper of the shoe.
  • the shape of these two surfaces 5 and 6 is defined by the standard.
  • the front toe of the shoe is retained in the front fastening element rather by its sole part, or rather by its stem part, i.e. the jaw of the fastener is in contact with or the sole surface 5, or with the upper surface 6.
  • Figure 2 shows the outline of the front end, seen from above.
  • surfaces 5 and 6 are symmetrical with respect to the vertical median plane, the trace of which is shown diagrammatically at 8 in FIG. 2.
  • Surface 5, seen from above, has in its central part the shape of an arc of circle of large radius, which is bordered laterally on each side by an arc of circle of smaller radius.
  • the rod surface 6, seen from above has the shape of an arc of large radius circle.
  • the jaw of the fastening element retains the shoe by a contact located in these areas, either by a plug on rod, or by a taken on sole.
  • a lateral stress exerted by the shoe on the jaw beyond the release threshold of the fastener causes movement lateral of the jaw.
  • the tip of the shoe slides along a side edge of the jaw, until it escapes completely to this one. The shoe is thus released.
  • the shoe is in contact with the jaw only in the standardized area of the front end, and more precisely only in a right or left part of the upper or sole.
  • Figure 3 shows a top view of the front toe of a shoe according to a first embodiment of the invention.
  • This figure shows in 15 the sole surface, and in 16 the rod end surface. Also shown in 18 is the trace of the plan median, and in 19a, 19b, 20a, 20b, the tangents to the sole surface and the stem surface, which approximately locate the contact areas between the nozzle and its retaining element.
  • the rod and / or sole are made asymmetrical with respect to the median plane.
  • Figure 3 shows on the left side of the median plane 18, portions of surface 15b and 16b of traditional form.
  • the dashed lines 15 'and 16 ' represent the symmetrical image of the portions 15b and 16b with respect to the plane median 18.
  • surfaces 15 and 16 have a straight portion 15a and 16a, which is substantially set back from the portion symmetrical 15 'and 16' corresponding.
  • the surfaces 15a and 16a are set back between the areas of tangency with planes 19a and 20a and the median plane so as not to modify the conditions under which the shoe is retained in a centered position by a retainer.
  • the general curvature of the surfaces 15 or 16 does not has no marked discontinuity in this recessed area.
  • the right portion of upper or sole surface gradually moves away from the symmetrical portion then gradually approaches it, between the zone of contact with the tangents 19a and 20a and the trace of the median plane.
  • the shoe of Figure 3 behaves as follows. In position centered, the shoe is retained in an element before fixing the same way than a traditional shoe.
  • the shoe requests the fastening element by its straight portion, it will be able to escape more easily from the jaw of the binding, thanks to its contact surface with the fastener which is set back from a traditional shoe. The release of the shoe is therefore facilitated on one side compared to each other.
  • the shrinkage is present on both the upper surface and the sole surface, so that a easier release is achieved as well with the fasteners standard to grip on rod than those to grip on sole. It goes without saying that the withdrawal could be present only on the stem surface, or only on the sole surface.
  • the other shoe has one or more withdrawals of the same type, but on the other side of the shoe.
  • the both knees of the skier are better protected by a release of the shoe easier on the side where the knee is more fragile. It should be noted that this result is achieved without requiring a pairing of the skis with the shoes, that is to say that the skier does not need to locate a straight ski and a left ski, it can fit each ski either on the right side or on the side left.
  • Figure 4 relates to another embodiment of the invention.
  • the sole 25 and upper 26 surfaces have a traditional shape.
  • the end piece present on the right side of the median plane 28 a recess 21 at the sole, and 22 at the tip.
  • the recesses 21 and 22 extend over the height of the standard zone, over substantially the length of the upper and sole surface portion located in a side of the midplane and they are filled with a wafer of low material friction 23, 24, for example a polytetrafluoroethylene plate.
  • This plate has a thickness equal to the depth of the recess, and it is assembled to the rest of the shell of the shoe by any appropriate means, and by example by collage.
  • FIG. 5 shows the recesses of the upper and the sole occupied by a series of vertical rollers or needles shown diagrammatically at 29.
  • the portion of the nozzle at low friction is the external surface 35a, 36a of an insert 33 produced in a material with lower friction than the rest of the tip.
  • a ski boot shell is made of polyurethane or polypropylene.
  • the added element can be made in this type of material but with the addition of graphite, polytetrafluoroethylene fillers or silicone oil.
