Definitions

  • This invention relates to a method for adjunct control of the free volume between the outer shell and the inner shoe in an article of sport footwear, and to an article of footwear, such as a skiing or skating boot and the like, with adjunct control of the free volume between the outer shell and the inner shoe in accordance with the method.
  • the inner shoe padding is designed to allow the inner shoe to adapt itself to the user's foot morphology so as to properly match its shape at least in some critical areas of the boot/foot fit. Accordingly, the inner shoe is to act as a soft compliant structure intervening between the foot and the boot shell, while the much stiffer structure of the latter provides support for the foot.
  • a new boot may not fit tightly around the user's foot, in the former case, or may undergo in use a deterioration of its original performance features due to local padding compression, in the latter case. Understandably, these are but two instances of typical problems encountered with footwear of this kind, and more may actually appear which are all tied to the accuracy of fit of the padding and that of the attendant support afforded to the user's foot.
  • a free volume develops between the inner shoe and the outer shell which adversely affects the tight fit and comfort to be expected from the boot. Notice that the term "free volume” encompasses here those spaces and interstices where the inner shoe and outer shell are held apart as well as areas between the shoe and the shell where the compressive state of the padding falls below predetermined optimum values.
  • a method for adjunct control of the free volume between the outer shell and inner shoe of an article of sport footwear characterized in that it comprises the steps of: fitting an auxiliary padding over the inner shoe such that it is interposed between said shoe and shell, said auxiliary padding having a resin injection chamber defined therein; injecting said resin in a flowable state into said injection chamber to mold said auxiliary padding such that it will at least partly fill said free volume between the outer shell and the inner shoe; and allowing said resin to cure.
  • an article of sport footwear such as a skiing or skating boot and the like, incorporating adjunct control of the free volume between the outer shell and the inner shoe by the above-outlined method, comprises an outer shell and a padded inner shoe inserted into said shell, and is characterized in that it comprises an auxiliary padding fitted over the inner shoe to intervene between the inner shoe and the outer shell, said padding having an injection chamber defined therein for a resin in a flowable state, capable of subsequent curing into said auxiliary padding to at least partly fill the free volume between the outer shell and the inner shoe.
  • a ski boot having an outer shell 2, typically made of a plastics material, and a padded inner shoe 3.
  • the shell 2 and shoe 3 are quite conventional both in shape and construction.
  • the user can initially control that free volume by so pulling the conventional fastening means (not shown because foreign to this invention) provided as to tighten the boot shell against the inner shoe.
  • the action of this first adjustment is applied to the shell as a whole, to generally tighten it down onto the inner shoe and is, therefore, comparatively inaccurate.
  • auxiliary padding 4 in the typical form and arrangement of an ankle support, which is fitted over the inner shoe, as shown in Figure 2, so as to intervene between the shoe and the shell 2.
  • the auxiliary padding 4 is bag-shaped and comprises two walls 4a,b sealed to each other all around their periphery so as to define an injection chamber 5 therebetween. Said walls are substantially impervious to resins in a flowable state for injection into the chamber 5 through a thin tube 6 leading to said chamber from outside the boot 1.
  • the next step of the inventive method provides for the boot to be donned, fastening it as desired onto the user's foot, and injecting through the tube 6 a resin in a flowable state, which resin will then expand and cure after a time selected to be reasonably short.
  • the cured resin inside the auxiliary padding 4 is indicated at 10.
  • Suitable resins are, for example, polyurethane or silicone or the like resins having appropriate compositions for injection in a flowable state and optional expansion before curing.
  • the tube 6 is cut off close to the shell 2.
  • the auxiliary padding 4 can be molded to at least partly fill the free volume between the outer shell and the inner shoe.
  • the shoe 3 is unattached to the auxiliary padding 4 at toe 7 and heel 8 areas thereof, because in these areas, the auxiliary padding is formed with openings whose edges are denoted by 7a and 8a. These openings are effective to promote blood circulation to the foot toes and heel by avoiding too constrictive an action on the foot in such areas.
  • Indicated at 9 is an additional opening through which the auxiliary padding 4 can be fitted over and removed from the inner shoe 3.
  • auxiliary padding can be taken out of the inner shoe 3, and hence of the boot 1, after the resin 10 has been injected and cured. This is simply performed by taking out the inner shoe through the boot entry opening 9, and conversely, replacing it into the auxiliary padding. This allows the boot fit to be reiterately modified to suit in the course of the boot service life and/or to meet specific foot clamping requirements, as may be the case where the boot is used for contest purposes.
  • the method of this invention, the boot obtained thereby, and the auxiliary padding employed may undergo changes and modifications within the same inventive concept.
  • the tube 6, which in the embodiment described is passed through the outer shell 2 could be passed between the shell and the inner shoe.
  • portions of the auxiliary padding may be left out of the injection chamber and/or the auxiliary padding may be made to a pattern other than that shown herein.
  • auxiliary padding having the walls 4a,b arranged to define a sealed bag-shaped enclosure, again in the form of an ankle support, into whose chamber 5 a compressible fluid, preferably air, would be introduced.
  • the enclosure would be pre-filled with air under a desired pressure at the manufacturing stage and the tube 6 omitted.
