Definitions

  • the subject of the invention is a comfort bootie mainly made of foam and fitted with a frame outer for sports shoe such as shoe ski or skate shoe.
  • Such a bootie is known from the patent application WO 96/13183 and of patent EP 0 657 112.
  • the liner is thermoformable and it is planned to thermoform it on a form.
  • the material used such as PE and PVA could be thermoformed on foot.
  • Thermoforming a comfort liner in located on the user's feet is known for many years and it is described in particular in documents such as EP 0 004 829 and JP 246 876.
  • the invention aims improve the fit of a comfort liner fitted a frame with the morphology of the foot of the user.
  • the comfort boot according to the invention is characterized in that its frame is made of material thermoformable in situ.
  • the foam could also be made of material thermoformable in situ.
  • the invention also relates to a method of setting in the form of such a comfort bootie, characterized by what we have the bootie with its frame in shoe and heat the frame, and the case also the foam of the liner, at its VICAT softening temperature, then introduces the foot or a molding of the user's foot in the liner and closes the shoe until the reinforcement material and, where applicable, also liner, either sufficiently cooled.
  • Reading the document FR 2 739 760 shows how much the idea of thermoforming a reinforcement in situ was far from the minds of inventors. It says in effect in this document that we noticed so not obvious a priori that direct heating of the lining, i.e. the liner, arranged inside of the shoe was not likely to damage or soften the outer rod of the latter. The man of the trade was therefore led to fear that the heating slipper also does not soften its frame.
  • Another object of the invention is to define a type of frame whose shape is particularly good suitable for strengthening a liner, especially if this reinforcement is intended to be thermoformed in situ.
  • Figure 1 shows a slipper with its frame.
  • Figure 2 shows the frame only.
  • the boot shown in Figure 1 includes a rod 1 made, in known manner, of a flexible material covered with a layer of synthetic foam thermoformable, for example a thermoplastic foam with closed cells such as PE-tBDL (polyethylene linear) or EVA (ethylene vinyl acetate), i.e. low density polyethylene with a VICAT softening temperature (standard NF T 51-021) relatively low.
  • a layer of synthetic foam thermoformable for example a thermoplastic foam with closed cells such as PE-tBDL (polyethylene linear) or EVA (ethylene vinyl acetate), i.e. low density polyethylene with a VICAT softening temperature (standard NF T 51-021) relatively low.
  • PE-tBDL polyethylene linear
  • EVA ethylene vinyl acetate
  • VICAT softening temperature standard NF T 51-021
  • the liner has a tongue 2 and a frame 3 also in thermoformable material having a relatively low softening temperature and in all cases below 100 ° C under load of 1kg.
  • This material is preferably a polyethylene with low density such as PE-tBDL having a softening temperature under load of 1kg below a range of 50 to 83 ° C or EVA with a softening temperature of 60 to 80 ° C for a comonomer content of 5 to 20% for a softening temperature below 50 ° C for 25 to 40% comonomer content, or EMA (ethylene metacrylic acid) or EAA (ethylene acid acrylic) with temperatures respectively softening from 63 ° C and 84 to 74 ° C.
  • PE-tBDL having a softening temperature under load of 1kg below a range of 50 to 83 ° C or EVA with a softening temperature of 60 to 80 ° C for a comonomer content of 5 to 20% for a softening temperature below 50 ° C for 25 to 40% comonomer content
  • EMA ethylene metacrylic acid
  • EAA ethylene acid acrylic
  • the frame can be made of solid injected material or alveolar or a combination of these two materials.
  • the frame 3 has a central portion 3a extending on the back of the foot, above the heel area. From this part 2a extend downwards two parts 3b and 3c which pass under the malleolar region to go up towards the instep. Of the game central 3a also go upwards two 3d and 3rd branches that extend, slightly obliquely forward, on each side of the area tibial.
  • This frame ensures optimal maintenance of the foot and ankle. It also provides precise transmission of forces between the leg, plus especially the shin, and skiing without creating annoying, even painful, pressure on vessels blood. When skiing, the movement of the shin gives the direction of the edge grip, that is to say the side of the ski on which the leg will take support. This transmission of the tibial support is therefore essential in edge grip and precision of this edge take.
  • the immediate transmission of forces between the ski and the leg is essential, but it should not be do at the expense of comfort. Indeed, if the skier experience pain, even slight, due to compression blood vessels or a bone tip, this feeling of discomfort results in a feeling insecurity. It is therefore important that the frame of the slipper does not cause this feeling of discomfort.
  • the shape of the frame 3 fulfills these conditions. This form could deviate from form represented.
  • the frame 3 could also equip a liner with comfort not thermoformable in situ. She might be made of a material other than a thermoformable material.
  • the liner can be heated, for example with air hot.
