Definitions

  • the subject of the present invention is a comfort boot for ski boots comprising a vamp enveloping the foot and a plastic rod intended to at least partially surround the lower leg and the internal face of which is provided with projections distributed over a part at less than its surface.
  • a ski boot liner must perform several functions, namely, the adaptation of the shell to the shape of the foot, thermal insulation, comfort and the interface function between the shell and the foot for the transmission of information. and orders between ski and foot and vice versa. These functions are largely contradictory if we consider that morphological adaptation and comfort suppose flexibility and compressibility, while the interface function supposes a close and rigid contact.
  • booties Basically two methods of manufacturing booties are known, molding and coupling of foams.
  • the molding provides the desired anatomical shape.
  • the comfort obtained is average.
  • the interface function it is very poorly fulfilled due to the uniform compressibility of the liner, that is to say the compressibility which is too high in the support zones used particularly for the transmission of the reactions of the ski and the foot and leg orders when skiing.
  • patent FR 2 690 814 is described a comfort liner having an at least partially extensible upper and on the external face of which are fixed a plurality of wedging elements in order to obtain a compromise between a controlled compressibility of the 'thickness of the liner, which may be different from one zone to another, and a transverse elastic extension of the upper to allow the passage of the foot without resorting to a tongue.
  • Wedging elements made of different materials are used in order to obtain different compressibility zones.
  • patent CH 608 349 it is also proposed to produce an inner liner essentially of expanded polyurethane provided on its internal face with projections coming directly into contact with the foot and the ankle.
  • the capacity for compression deformation and a variable density of distribution of the protrusions on the surface of the liner make it possible to create different zones of compressibility with the aim of simultaneously ensuring the comfort of the foot and a good grip of the latter necessary for precise driving. ski.
  • the distribution of the projections has a greater density in the region of the malleoli so as to obtain a greater capacity for deformation.
  • the projections therefore fulfill the function of a foam which would have a substantially greater thickness in the malleoli region and other comfort zones, while it would be thin in the other zones.
  • the object of the present invention is to obtain, essentially by molding, a liner that best meets the requirements of anatomical shape, comfort and technicality mentioned above.
  • the pins of different heights allow to obtain a relief adapting to the morphology of the skier's foot.
  • the studs can be in direct contact with the foot, but the liner is preferably provided with an interior foam lining covering the studs.
  • the variable height and, if necessary, the density of distribution of the pins and / or their variable section, in this case delimit a more or less large space in which the foam can penetrate during its compression, which also makes it possible to obtain zones having different characteristics with regard to the deformation capacity, the capacity for recovering the initial shape after cessation of compression, the reaction time to pressure, i.e. of the time measured until maximum deformation, this reaction time being decisive in the precision of the handling of the ski, and the capacity to adapt to the morphology, that is to say the capacity to deform while preserving still a certain compressibility, characteristic which one could call adaptability.
  • the invention makes it possible to obtain a slipper whose molded part, of variable thickness, adapts very well to the morphology of the foot and of the leg, good comfort and very good technicality due to the rigidity. selective support zones ensuring the interface function.
  • Figure 1 is a sectional view along I-I of Figure 2 through a ski boot fitted with a boot according to the invention.
  • Figure 2 is a cross-sectional view along II-II according to Figure 1, showing the shoe seen from above.
  • Figure 3 is a developed view in perspective of half of the plastic part provided with pins of the bootie of the shoe shown in Figures 1 and 2, that is to say, a bootie for the right foot.
  • Figures 1 and 2 give a schematic representation of a ski boot consisting of a shell 1 with variable volume and a rod 2 in the form of a collar.
  • the shell and the collar are for example made of polyurethane.
  • the shell 1 is provided with two tightening loops 3 and 4.
  • the same is true of the rod 2 of which a loop 5 has been shown in FIG. 2.
  • the loops have not been shown in FIG. 1, but recognizes therein two flaps 2a and 2b of the collar 2, flaps provided with the closure and tightening loops of the collar.
  • the shell 1 and the upper 2 house a comfort boot comprising an upper 7 surrounding the forefoot and the lower part of the heel and extending below the malleolus 8 of the foot 9 and of a rod consisting essentially of a plastic part 10 enveloping the rear of the leg and the ankle and extending on each side of the leg and the ankle and a tongue 6 covering a part 11 made of the same material as the part 10.
  • the parts 10 and 11 of the liner are provided with pins 12 directed inwards. As can be seen in FIG. 3, these pins 12, of slightly frustoconical shape, are not all of the same height and of the same diameter and the density of their distribution varies according to the zones considered.
  • Part 10 and part 11, fixed on the tongue 6, are furthermore coated internally with a layer of synthetic foam 13.
  • FIG. 1 schematically illustrates the perfect adaptation of the inner shape of the liner to the shape of the foot and the leg. As will be seen below, this adaptation is carried out without compression of sensitive areas and in a determined and controlled manner according to the areas
  • FIG. 3 represents the outer half of the part 10, that is to say the part s' spanning the outside of the right foot.
  • the other half is symmetrical, except for the deep cut 14 which separates the inner and outer parts in the area corresponding to the position of the Achilles tendon.
  • This cutout 14 does not extend along the axis of symmetry of the part 10, but it deviates from this axis of symmetry in the direction of the outside of the foot.
  • the pins 12 have come from molding with their support 10 and have a frustoconical shape.
  • the plastic used is for example polyurethane.
  • zones A, B, C, D and E There are three different types of zones designated by A, B, C, D and E.
  • the upper zone A, as well as zones B and C have only been represented by the marginal spikes of these zones.
  • the pins 12a of the zones A have an average diameter of 3 mm, a height of 4 mm and a pitch (center distance) of 6 mm.
  • the pins 12b in zone B have an average diameter of 4 mm, a height of 3 mm and a pitch of 6 mm.
  • the pins 12c of zone C have an average diameter of 5 mm, a height of 2 mm and a pitch of 7 mm.
  • the pins 12d in zone D have an average diameter of 2 mm, a height of 3 mm and a pitch of 4 mm.
  • the E zones are marginal transition zones having spikes of the same diameter and not the same as the neighboring zone, but of decreasing height.
  • the part 10 behaves like a part of variable thickness, more precisely as a part whose inner face has a relief of variable height.
  • the pins 12 define a depression M corresponding to the position of the malleolus. The latter can therefore be accommodated in this depression M.
  • the transition zones E adjoining the cutout 14 forms a housing for the Achilles tendon.
  • the relief formed by the pins 12 ensures an adaptation of the part 10 to the morphology of the lower leg.
  • the parts of this foam which do not bear on the pins penetrate into the spaces located between the pins by undergoing a deformation which varies from zero in the center, to a maximum value equal to the compression undergone on the pins.
  • the degree of penetration of the foam between the pins depends on the volume of the space between the pins, that is to say on the height, the diameter and the density of distribution of the pins. The degree of penetration of the foam contributes to giving the liner a particular behavior in compression.
  • zones A are zones having a relatively large deformation capacity. These are comfortable support areas. This is particularly the case of the posterior support zone A for the support of the calf.
  • the zones C are zones with short reaction time having a low capacity to deform and a low adaptability to the morphology. Zones C are therefore much more capable of transmitting the pressures involved in guiding the ski.
  • Zone B is an zone with characteristics intermediate between those of zones A and those of zones C.
  • additional zones F consisting of pins having a diameter of 3 mm, a height of 0.2 mm and a pitch of 6 mm.
  • the pins is made of one or more materials of different stiffness than that of the material forming the support of the pins. It is thus possible to obtain different compressibility zones by the sole choice of the suitable material. In this case, the pins can therefore have a uniform cross-section and density.
  • the part 10 supporting the pins can itself be made from a single material or from several different materials.
  • the effect obtained by the non-uniformity of the pins could be further amplified by the use of foams of different densities according to the zones.
  • the liner may not include foam 13, the pins 12 then being directly in contact with the foot or simply covered with a woven material or a felt. In this case, we would still take advantage of the particular structure of the liner, that is to say the internal relief adapting to the morphology of the foot, the variable ability from one area to another to deform and to adapt to the morphology of the foot by deformation.
  • the frustoconical shape of the pins is dictated by practical reasons of demolding. In principle, the pins could have a cylindrical shape, or even a non-circular section. The ends of the pins could be curved.
