Definitions

  • the invention relates to a ski boot, in particular with a lower shell which has an essentially longitudinally central opening, as well as a cover for bridging this opening and a shaft part which can be pivoted in relation to the lower shell in the longitudinal direction of the boot and, if necessary, a heel-side opening which can be closed by means of a preferably pivotable lid, with a Sole part which has at least one shoulder and a tip part which extends back into the ball section, outside and preferably below the lower shell a longitudinal stiffening extending between the heel and the tip part is provided.
  • the modern shells of ski boots which are made of plastic materials, are intended to ensure good power transmission from the skier's foot to the ski and, for this purpose, be as torsionally rigid as possible in the longitudinal direction. If a very stiff or thick material is used to achieve this purpose, this has the disadvantage that it makes it difficult to get in and out of the boot, especially at low temperatures when using the ski boot.
  • the overlap in the so-called overlap shoes - shoes in which the lower shell consists of two side parts which at least partially overlap in the longitudinal direction - is very difficult to open and also in shoes with, for example, a longitudinal opening in the instep and flexion area, which are covered by a cover is bridged, the two side parts of the lower shell are difficult to bend apart for getting in and out.
  • a ski boot of the type mentioned in the opening paragraph is known from US-A-4,998,358.
  • the longitudinal stiffening is in the form of two longitudinal bars connecting the tip part to the heel.
  • These longitudinal poles have the disadvantage that they do not exert any torsional rigidity and therefore only allow poor transmission of power from the skier's foot to the ski.
  • a shoe sole structure has become known from DE-A1-27 23 884, in which a wire element is provided between the heel and tip of the shoe sole, which is connected via support elements on the one hand to the sole heel and on the other hand to the sole tip.
  • This construction also has the same disadvantages as the one described above.
  • the longitudinal stiffening around the longitudinal axis of the boot is torsionally rigid and is preferably screwed to the lower shell in the region of the heel and the tip part.
  • This feature provides a stiffening of the shoe against torsion about the longitudinal axis of the shoe by the additional longitudinal stiffening, while the shoe itself can be made of the soft plastic material which is advantageous for facilitating getting in and out as well as adapting to the shape of the foot. Since the longitudinal stiffening additionally provided in the sole area of the shoe does not form an integral part of the shell, there is also no cold bridge over which the inside of the shoe can cool down and get into the shoe via the cold.
  • the longitudinal stiffening is a profile, preferably a hollow profile.
  • the heel and the toe part possibly also the corresponding areas of the sole and / or the underside of the lower shell, have mutually facing recesses with axes oriented essentially parallel to the longitudinal axis of the ski boot, into which recesses the longitudinal stiffening is inserted.
  • An advantageous embodiment of the invention is characterized in that the heel and / or the toe part, at most the entire sole, are manufactured independently of the lower shell and at most releasably connected to these parts, the connection of the longitudinal reinforcement to the ski boot by the connecting means of the sole or the paragraph and / or the top part is given.
  • the attachment of the longitudinal stiffening and, if necessary, its replacement - and thus both a possibility of repair and adaptation to different slope conditions or physical conditions of the skier - can be carried out more easily or is possible in the first place.
  • the longitudinal stiffening is advantageously made of a light material such as carbon fiber composite, aluminum or aluminum alloys, etc. in order not to unnecessarily increase the weight of the shoe.
  • FIG. 1 shows the lower shell 1 of the ski boot according to the invention, which also comprises a sole 11 in connection with the shaft section 12 which can be pivoted in the longitudinal direction of the boot with respect to the lower shell 1.
  • a cover 13 which can also be pivoted in the longitudinal direction of the shoe is provided. After boarding, d. H. while the shoe is in use, this is by means of known closure devices attached to the lower shell 1, the shaft part 12 and / or the lid 13, for example by means of the buckles 5 or one or more shown, from one side of the lower shell 1 to the opposite side running rope (s), closed.
  • a flexion movement of the foot is preferably possible due to the longitudinally pivotable attachment of the shaft part 12 via the connection 14 and also the rear cover 13 (connection not shown).
  • a cover 15 for the essentially longitudinally central opening 16 of the lower shell 1 is provided essentially in the longitudinal center of the shoe.
  • the lower shell 1 of the ski boot according to the invention can be made of all materials used for the production of shells for ski boots, for example of polyurethane, and has a sole 11 with a heel 2 in the heel area of the foot and a toe part 3 extending into the ball area below the forefoot on.
  • the shoulder 2 and the toe part 3 can be separate parts (see FIG. 3), in which case an area 4 of the underside of the lower shell 1 lies between these parts 2, 3, or can be provided with a connecting piece 9 in order to form a continuous sole (see Fig. 4).
  • the longitudinal stiffening 10 made of a light but torsionally rigid material, for example made of a carbon fiber composite material or aluminum or an aluminum alloy .
  • the longitudinal stiffening 10 extends approximately from the center of the heel part 2 to the front end of the tip part 3, whereby a larger longitudinal area of the shell 1 is covered by the stiffening effect of the longitudinal stiffening 10.
  • a recess 6 in the paragraph 2 and a recess 7 in the tip part 3 are provided, into which recesses 6, 7 the front or rear end of the longitudinal reinforcement 10 is inserted.
  • connection of the longitudinal reinforcement 10 to the lower shell 1 of the ski boot can be carried out in any, preferably detachable manner, both to mount the longitudinal reinforcement 10 and to replace it in the event of a repair or adaptation of the ski boot to slope conditions or special wishes or circumstances of the skier
  • the longitudinal reinforcement 10 is therefore preferably connected to the lower shell 1 by means of two screws 8 at each of its front and rear ends, which ends are preferably located within the shoulder 2 or the tip part 3. But gluing, riveting or any other possible type of connection would also be conceivable.
  • Fig. 3 it is expressed that the paragraph 2 and / or the toe part 3 can be manufactured separately and then connected to the lower shell 1 of the ski boot.
  • the connection of the longitudinal reinforcement 10 to the lower shell 1 and the connection of the heel 2 and / or the toe part 3 to the lower shell 1 are advantageously combined, and both connections are realized by the screws 8.
  • the screws 8 hold in this case both the paragraph 2 or the tip part 3 and within the Recesses 6 and 7 of these parts received longitudinal reinforcement 10 against the lower outside of the lower shell 1.
  • the upward-facing side of the longitudinal reinforcement 10 and the underside of the lower shell 1 so that a good fit of the longitudinal reinforcement 10 is ensured over the entire length, whereby but nevertheless - due to the non-continuous material course between the longitudinal reinforcement 10 and the lower shell 1 - no cold bridges are formed.
  • a sole 11, as shown in FIG. 4, can also preferably be detachably connected to the lower shell 1, advantageously both the sole 11 and the longitudinal reinforcement 10 by the screws 8, rivets or the like on the lower shell 1 are attached.
  • An underside of the connecting region 9 which is complementary to the longitudinal stiffening 10 is also advantageous here.
  • recesses corresponding to or complementing the recesses 6, 7 can also be provided in the front and rear area of the outside of the lower shell.
