Definitions
- the present invention relates to a comfort bootie for ski boot including an enveloping upper the foot and a plastic rod intended to at least partially surround the lower leg and the internal face of which is provided with distributed projections on at least part of its surface.
- a ski boot liner must provide several functions namely, adapting the shell to the shape foot, thermal insulation, comfort and function interface between the shell and the foot for the transmission of information and orders between the ski and the foot and vice versa. These functions are largely contradictory part if we consider that the adaptation morphological and comfort presuppose flexibility and compressibility, while the interface function assumes close and rigid contact.
- the molding provides the desired anatomical shape.
- the comfort obtained is average.
- the interface function it is very poorly filled due to the compressibility uniform of the bootie, that is to say of the too high compressibility in support areas used particularly for the transmission of reactions from skiing and foot and leg orders to ski.
- patent FR 2 690 814 is described a slipper of comfort with at least partially extendable upper and on the outside of which are fixed a plurality of wedging elements for the purpose to obtain a compromise between controlled compressibility the thickness of the boot, likely to be different from one area to another, and an elastic extension transverse of the rod to allow passage foot without using a tongue. Elements of dunnage in different materials are used in order to obtain different compressibility zones.
- patent CH 608 349 it, in accordance with the preamble of the claim 1, is further proposed to make an inner liner essentially in 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 projections on the surface of the slipper allow to create zones of different compressibility in order to simultaneously ensure foot comfort and good grip last necessary for precise control of the ski.
- the projection of projections has greater density in the malleolus region so as to obtain greater capacity for deformation.
- the projections therefore fulfill the function of a foam which would present significantly greater thickness in the malleolus region and other comfort zones, while that it would be thin in the other areas.
- the object of the present invention is to obtain a bootie meeting as best as possible the formal requirements anatomical, comfort and technicality mentioned above.
- the boot according to the invention has the characteristics defined in claim 1.
- the pins of different heights allow to obtain a relief adapting to the. morphology of the skier's foot and, on the other hand, the variable height and, where appropriate, the density of distribution of the pins and / or their variable section, delimit a more or less large space in which the foam can penetrate during compression, which provides areas with different characteristics with regard to the deformation capacity, the recovery capacity of the initial form after cessation of compression, the pressure reaction time, i.e. of the time measured until maximum deformation, this reaction time being decisive in accuracy of skiing, and the ability to adapt to the morphology, i.e. the ability to deform while still retaining some compressibility, characteristic which one could call adaptability.
- the invention makes it possible to obtain a slipper whose molded part, of variable thickness, adapts very good at the morphology of the foot and the leg, a good comfort and very good technicality due to the selective rigidity of the support zones ensuring the interface function.
- Figures 1 and 2 give a schematic representation a ski boot consisting of a shell 1 to variable volume and a rod 2 in the form of a necklace.
- the shell and collar are for example made of polyurethane.
- the shell 1 is provided with two tightening loops 3 and 4. It is the same for the rod 2 which is shown a loop 5 in Figure 2. Loops have not been shown in Figure 1, but we recognize in it two flaps 2a and 2b of the collar 2, flaps provided with collar closure and tightening loops.
- Shell 1 and upper 2 house a comfort liner comprising an upper 7 surrounding the forefoot and the bottom of the heel and extending below the malleolus 8 of the foot 9 and a rod consisting essentially of a part 10 of enveloping plastic material the back of the leg and ankle and extending on each side of the leg and ankle and a tongue 6 covering a portion 11 at the same material as part 10.
- Parts 10 and 11 of the liner are provided with pins 12 directed inwards. As can be seen in Figure 3, these pins 12, slightly frustoconical in shape, are not all of the same height and diameter and the density of their distribution varies according to the zones considered.
- the part 10 and part 11, fixed on the tongue 6, are further coated internally with a layer of synthetic foam 13.
- Figure 1 schematically illustrates the perfect adaptation of the interior shape from the boot to the shape of the foot and the leg. As we will see later, this adaptation is carried out without compression of sensitive areas and in a determined manner and controlled according to the lower leg areas.
- the height and variable mean diameter of the pins 12 as well as their distribution appear clearly on the perspective view shown in the figure 3.
- This figure represents the outer half of the part 10, that is to say the part extending over the outside of the right foot.
- the other half is symmetrical, except for the deep cut 14 that 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 from part 10, but it deviates from this axis of symmetry towards the outside of the foot.
- the pins 12 came from molding with their support 10 and have a frustoconical shape.
- Plastic used is for example polyurethane.
- A, B, C, D and E There are three different types of designated areas by A, B, C, D and E.
- the upper zone A, as well as zones B and C were only represented by the pins marginal areas.
- the pins 12a of 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 in zone C have an average diameter of 5 mm, a height of 2 mm and a pitch of 7 mm.
- the pins 12d of 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 pins of the same diameter and of the same pitch than the neighboring area, but of declining height.
- room 10 behaves like a variable thickness part, more precisely as a part whose inner face has a relief of variable height.
- the pins 12 delimit 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 tendon Achilles.
- the relief formed by the pins 12 ensures an adaptation of the part 10 to the lower leg morphology.
- the parts of this foam which do not take no support on the pins penetrate into the spaces located between the pins undergoing a deformation which varies from zero in the center, to a maximum equal value to the compression undergone on the pins.
- the degree of foam penetration between the pins depends on the volume of the space between the pins, that is to say of the height, diameter and density of distribution spikes. The degree of penetration of the foam contributes to give the slipper a particular behavior in compression.
- zones A are zones exhibiting relatively large deformation capacity. This are comfortable support areas. It is notably the case of the posterior support zone A for the support of the calf.
- zones C are zones with short reaction time with low capacity to deform and poor adaptability to the morphology. C zones are therefore much more suitable for transmit the pressures involved in guiding ski.
- Zone B is an area 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 that of the material forming the support of the pins. It is thus possible to obtain compressibility zones different by the only choice of material adequate. In this case, the pins may therefore have uniform cross-section and density.
- the part 10 supporting the pins can be itself in a single material or in several different materials.
- the effect obtained by the non-uniformity of the pins could be further amplified by the use of different densities depending on the area.
- the frustoconical shape of the pins is dictated by reasons mold release practices. In principle, the pins could have a cylindrical shape or even a non-circular section. The end of the pins could to be bulging.
