Definitions

  • the invention relates to a method for producing an inner shoe for ski shoes by foaming the inner shoe in situ, the foot of the wearer wearing a double-walled stocking being placed in the shoe and the foam mass being introduced into the double-walled stocking in the lower part of the shoe and the displaced air is omitted at the top of the same.
  • a method of this kind has become known from US Pat. No. 3,834,044. It has the advantage that the shoe is adapted exactly to the shape of the wearer's foot.
  • a filling hose arranged in the longitudinal median plane of the shoe leads the foam into a free space in the heel area, from where the fully reacting foam is distributed uncontrollably to the front and upper part of the shoe.
  • the inner boot of ski boots usually extends beyond the ankle. The foam in reaction first comes into a large-volume space, expands in it and only then does the foam move uncontrollably into the upper and the tip area, which has a much smaller volume.
  • the air between the inner shoe lining and the outer skin is displaced by the chemical reaction of the components and exits to the outside through a ventilation hose arranged in the upper heel area of the shoe.
  • the foam therefore moves in the direction of least resistance.
  • the air to be displaced is not completely discharged through the ventilation hose, but remains trapped, especially in the toe but also partially in the upper liner area, and forms air bubbles.
  • the traffic jam delays the replenishment of unreacted foam. Since the reaction takes place within narrow limits, it can happen that the front parts are not or only insufficiently foamed by delaying the flow rate. Maintaining the component temperature, which affects the reaction time, among other things, is extremely difficult to maintain in retail.
  • FR-A-2 541 095 pulls a liner, generally longitudinally divided in the instep and front cuff area, which has openings in the front area for admitting the foam mass and openings in the upper area of the cuff for exhausting the displaced air.
  • the filling happens simultaneously on both sides.
  • the foam mass gives the most compact padding in the forefoot area, since it is applied with the greatest pressure, while in the most stressed ankle area the foam is less dense.
  • the object of the present invention is to eliminate the disadvantages of the known methods and to take measures so that the foam mass reaches the ankle area with a relatively high pressure, so that at this point where the foot is subjected to the greatest lateral pressure stress, there is compact, sufficient padding without that in the other foamed parts of the inner shoe dead spaces are formed by air pockets.
  • the foam or the mass used to foam out the shoe is introduced on both sides of the shoe in the region between the ankle and instep.
  • foaming from the front foam is first foamed over the naturally narrow areas and only then does the foam drift into the larger free space or heel area.
  • Backlog formation is avoided by the given physically correct flow direction and only through this technology can the disadvantage of asymmetrical foaming be avoided. Due to the targeted and simultaneous foaming of the instep and ball area, the set foot remains in its position and is not pushed out of the axis.
  • the mass is expediently introduced to the right and left of the longitudinal axis of symmetry of the stocking, preferably at the same time. This results in an even distribution of the foam.
  • the two spaces in the front area of the shoe into which the foam or the mass is introduced are expediently separated from one another.
  • 1 denotes a ski boot shell, which is articulated to a cuff 2 to protect the ankle area of the skier's foot.
  • 3 is the inner shoe, which consists of an inner lining 4, an outer lining 5 and a sole 6, the space between the inner and outer lining being filled with a foam material 7.
  • the inner shoe 3 is foamed in such a way that the inner lining and the outer lining in the form of a hollow stocking is pulled over the feet of the skier dressed with ski socks, which along the entry opening, i.e. is sewn along the upper edge and the instep opening to be laced or otherwise closed.
  • a stronger fabric is predominantly used, which is sealed on the side facing the cavity by a rubber layer, while the outer lining e.g. thin leather, plastic material or the like. is used.
  • Near the upper edge of the outer lining 5 there is an outlet opening 8 on each side of the longitudinal center plane and in the region of the lower end of the instep opening an inlet opening 13 is provided on both sides of the longitudinal center plane.
  • a hose 9 or 10 leads from the outlet openings and the two inlet openings via corresponding openings from the shell 1 or sleeve 2.
  • various changes can be made to the number and arrangement of the outlet openings. It is thus possible to arrange only one outlet opening on the heel side in the longitudinal center plane.
  • the foam or mass is introduced in the flex area of the shoe between the ankle and instep.
  • the foam bottle is connected to the two ends of the hose 10 by means of an adapter, whereupon the foaming is carried out until foam emerges from the outlet hose 9.
  • the mass is preferably introduced simultaneously in the flexion area of the foot via the tubes 10 on the left and right of the longitudinal median plane, the mass flowing, as indicated by the large arrow 15, first against the heel and then towards the tip and partly also towards the ankle spreads. As the mass spreads, the majority of the air escapes through the hoses 9 in the upper region of the stocking 14, so that no dead spaces can arise.
  • the stocking 14 can be sewn on the tip side, as shown in dashed lines at 24, so that the mass cannot reach to the toe.
  • the non-foamed tip part then has a soft, glued-on lining on the inside to achieve protection against the cold. This measure enables better freedom of movement of the toes. Then the hoses 9, 10 are pulled out jerkily and the inner shoe is removed from the outer shoe. The openings for the hoses 9, 10 are expediently closed by covering caps, whereupon the inner shoes are inserted into the shell 1.
  • the stocking 14 is equipped in such a way that air, but not foam, can escape at least in the instep and partly also in the heel area.
  • This object is achieved in such a way that the material of the stocking 14 is air-permeable but essentially foam-impermeable, for example a fabric, or that the stocking 14 consists of air- and foam-impermeable material. for example made of leather or plastic, at least at the places where air should escape, corresponding pores, fine openings, or the like. be formed.
  • the hollow stocking 14 can be produced from a plurality of stamped parts which are sewn together, the air being able to escape at least at the seams and / or on natural or artificially produced pores. Of course they have to Seams, pores or the like not be designed so that only air can escape; rather there is the possibility that even through individual seam stitches, pores, or the like. Traces of the foam mass can escape, but this does not affect the quality of the liner.
  • the stocking 14 preferably consists of a left and a right stamped part; These stamped parts are sewn together in the middle on the tip and heel sides and form the outer wall of the stocking.
  • the inner wall of the stocking is formed by the inner lining 4, which is sewn to the two stamped parts in order to form the hollow stocking 14.
  • An eyelet band 16 is formed in the instep area by means of one seam 17 each. All stamped parts with a sole part 25, e.g. made of leather or plastic, sewn together to prevent the mass from penetrating under the foot.
  • the seam 17 prevents the mass from penetrating into the interior of the eyelet band 16, but, like all other seams, allows the air to escape.
  • a tongue (not shown) is sewn onto the lower end of the eyelet band 16 or at the beginning of the central seam of the two stamped parts at the top of the stocking.
  • a sleeve-like support part 18 is also attached to the stamped parts by sewing.
  • the heel-side connection of the two stamped parts can also be made by a strip of leather or plastic (not shown) which is sewn to the stamped parts.
  • a foam composition based on polyurethane is advantageously selected. If the ski shoe parts or at least the shell of ski boots, which consist of shell and shaft, are made of plastic based on polyurethane, a connection can be established between the shell and the mass if the shell side emerges.
