Definitions

  • the invention relates to an inner shoe, in particular for ski boots, hiking boots or the like, comprising a foot part, a shaft part and preferably also a tongue extending from the foot part up to the upper edge of the shaft part, the inner shoe being closed at least at one point with inner fluid-filled bubbles is provided. Further objects of the invention relate to a ski or mountain boot with this inner boot.
  • a molded part made of polyurethane in the form of a shoe sole has become known from AT-B 366 565, pressure-elastic hollow microspheres being enclosed in the polyurethane.
  • the distribution of such hollow microspheres in the wall of the inner shoe for the purpose of protection against the cold and uncomfortable pressure has not yet been satisfactorily resolved.
  • the object of the present invention is to provide a light and economically producible liner with a good protective effect at the vulnerable points.
  • the liner mentioned at the outset is characterized according to the invention in that the bubbles are provided in an upholstery embedded in the material.
  • the bubbles can be filled with a gas, for example air, a liquid or a gel, or with a pasty mass or a Mixture of these substances can be filled.
  • Gas or air bubbles are advantageously on the one hand a good heat insulator and on the other hand a good shock-absorbing or cushioning layer.
  • the upholstery used according to the invention has the advantage over foam materials that it is not moisture-absorbent, therefore does not store any liquid, and also does not lose its consistency or hardens in the areas which are preferably exposed to stress. This means that an inner shoe with high wearing comfort and a very good cushioning effect can be produced with also simpler and cheaper production.
  • the advantage of low weight is also important, so that a light liner with good insulation and comfort can be produced.
  • the bubbles are distributed irregularly in the volume of the material in a manner known per se, which surprisingly results in an even softer cushioning effect compared to regularly arranged bubbles in the material of the inner shoe.
  • the material is provided between the outer layer and the lining of the inner shoe so that damage to the material and possibly the connection to the basic structure of the inner shoe can be avoided.
  • the padding is provided in combination with a foam layer, the foam layer preferably having a larger area and extending beyond the edge of the padding.
  • This feature also protects the upholstery with the blisters against damage and detachment, whereby the advantages of the foam material are also introduced, such as the shape and adaptability to various, including anatomical, conditions, which can also be done subsequently by foaming on the foot. Larger distances between the foot and the inside of the shell of the shoe can also be bridged and compensated for more easily with foam.
  • the padding can advantageously be at least in the area around the Achilles tendon and / or the ankle and / or the instep, preferably up to the upper edge of the Shaft part, and / or be provided on the upper edge of the shaft part.
  • These areas of the liner are the most pressure-sensitive areas or the places where the foot should be adjusted or fixed.
  • the padding is in the form of a film, preferably a plastic film, with essentially the same thickness over the entire surface.
  • films are similar to those used as packaging material and can be cut accordingly for the areas of the foot to be protected.
  • the simple to manufacture and therefore cheap material also makes it possible to produce the entire inner shoe economically, and it was also found that this padding surprisingly adapts to the foot much better and is softer than, for example, foils with spaced apart and elevations forming the foil , fixed air or gas bubbles.
  • the invention also relates to a ski boot with an inner boot according to one of the preceding paragraphs, the inner boot being arranged unconnected in the ski boot, at most detachably connected to it, and thus being removable or removable.
  • the advantages also given in the previous paragraphs are therefore also realized for the entire shoe, with the inner shoe additionally being removed and separated from the outer shell, for example as a hut shoe, or in other shoes, ie. H. other outer shells can be used.
  • the inner shoe shown in Fig. 1 consists of a foot part 1, which encloses the wearer's foot from the toes to about the ankle. This is followed by a shaft part 2, which extends from the ankle to the area of the lower leg.
  • the foot part 1 and the shaft part 2 are preferably cut open in the longitudinal center of the inner shoe or have a longitudinal center opening that is formed by a tongue 3 is covered. At most, the tongue 3 can also lie below or within the longitudinal center opening of the inner shoe and be covered by its side parts.
  • FIG. 1 also marks those regions of the inner shoe which are advantageously provided with material containing fluid-filled bubbles, preferably gas or air bubbles, according to the padding according to the invention.
  • the material present in the vesicles can be selected depending on the desired cushioning and insulating properties and can also be formed by a gel, a liquid or a pasty mass. Mixtures of the substances mentioned can of course also be used. Gases have the advantage of low weight with good heat insulation and soft padding.
  • a substantially triangular section 4 of the padding is provided on the rear of the foot part 1, preferably up to a small distance into the shaft part 2, and covers the Achilles tendon and the area behind and above the ankle, running forward on both sides of the inner shoe from.
  • the ankle itself is protected by a likewise essentially triangular section 5, the opposite side of the inner shoe, which is not visible in FIG is essentially the same.
  • the section of the padding provided there is offset according to the different position of the outwardly protruding ankle section.
  • the Achilles tendon and the ankle-protecting sections 4 and 5 can be combined to form a part 9, which extends from the rear heel and tendon region of the inner shoe on both sides to the front, towards the tip of the inner shoe, runs.
  • the upper edge of part 9 is preferably at the height at which part 4 (FIG. 1) also has its upper edge, preferably above the ankle joint.
  • Fig. 2b the tongue 3 of an inner shoe according to the invention is shown schematically in perspective and it can be seen that it can also be provided with a section 10 of the cushioning material.
  • the tongue 3 can be arranged inside or outside of the inner shoe.
  • the upholstery in order to protect the upholstery from damage or detachment with the air or gas bubbles, it is arranged between the outer skin 11 and the inner lining 12 of the inner shoe, as shown in FIGS. 3a to 3c, in the simplest version without additional layers.
  • a conventional foam material 13 which is kept somewhat larger than the respective section 4 to 10 of the material containing the air or gas bubbles and projects beyond these sections at the edges, may also be present, which is also between the outer skin 11 and the lining 12 lies.
  • the foam material 13 is on the outside and the respective section 4 to 10 is on the inside or the arrangement, as shown in FIG. 3c, is reversed.
  • FIG. 4 shows a complete ski boot, consisting of a fixed outer shell 14 with an articulated shaft part 15 surrounding the lower part of the lower leg and an inner boot which realizes at least one of the features described above.
  • the upper edge of the inner shoe extends beyond the upper edge of the shaft part 15 and the sections 7 and 8 made of the cushioning material are also located in the region of the upper edge of the shaft part 15 or, as shown, protrude beyond and cover this edge against the The foot or lower leg of the wearer.
  • the material 4 to 10 is preferably in the form of a film which essentially has the same thickness everywhere. If individual areas of the inner shoe are desired thicker, either several layers of the film can be arranged one above the other or a foam layer can be provided to bridge the greater distance.
  • the inner boot according to the invention can be used for all types of shell shoes, including mountain roller skates or other sports shoes, boots or the like.
