Definitions

  • the present invention relates to a ski boot structure, and more specifically a monobloc ski boot structure.
  • ski boots have been manufactured in the form of a rigid shell made of plastics material, on which shell is hinged a lower leg envelopment, also made of rigid plastics material, ensuring that the boot is equipped with padding and inner boots which come into direct contact with the foot of the user, so that not only is damage to the foot avoided, but increased comfort in use is ensured without sacrificing the rapid and faithful transmission of the commands of the skier's leg and foot through the boot and the binding to the ski.
  • the lateral edges of the ski have "side cuts", or narrowed sections connected by wide radius arcs to the ends of the ski, so that the skier is obliged to act constantly on the edges of the skis and above all, in order to turn better, the athlete must act substantially in the central region of the ski, while in order to modity the radius of curvature he must increase or reduce (depending on the desired result) the lateral angulation of the system constituted by the boot, the binding and the ski.
  • the ski boot structure becomes a monobloc constituted by the shell alone, which preferably extends upwards to form or to substitute at least partially the part of the lower leg envelopment capable of receiving the lower portion of the tibia of the user, which shell is intended to receive padding and/or an inner boot of the known type.
  • one-piece ski boots have already been known in the past, but were made of hide, so that it was not feasible for them to provide a lower leg envelopment of the traditional type.
  • the lack of rigidity of the boot upper discouraged then, as now, its adoption for any application which requires faithful transmission of the commands of the skier's leg to the ski.
  • the prior art also includes one-piece boots produced when the structures made of plastics material are proposed and produced as a substitute for the hide boots, without it being possible, however, to provide the functional capability which is achieved with the boot structure according to the present invention.
  • the ski boot according to the present invention comprises a shell 10, produced for example by injection from a suitable plastics material, so as to produce both the shell 12 itself, the boot upper 14 and a sole 16 as one body.
  • an inner sole 18 for example wedge-shaped, while the boot upper extends upwards, differing in this respect from the shell of the traditional boots known hitherto, in forming a part similar to a lower leg envelopment 20 and intended to receive the lower end of the leg and the ankle joint.
  • the boot upper 14 is divided at the front into two halves 22A, 22B (Fig. 7), the edges of which define an opening which is elongate in a longitudinal direction in the front part of the shell 10, so that it is defined as a front entry boot, the opening preferably being closed by means of an added-on sealing element which prevents the penetration of snow and ice, and which may alternatively be produced in the form illustrated in Figures 5 and 5A or in that in Figures 6 and 6A.
  • the sealing element 24 is shaped at the lower end, or that nearest the toe of the boot, with a laterally deformed tongue 25 for end anchorage in a corresponding recess 27 formed in the part 14A of the boot upper.
  • the sealing element 24 is fixed to the edge 22A of the boot upper, for example by means of rivets which engage the holes 29, and has an enlargement 31 at the end, so that it forms a seal between the edges 22(A,B) and the fixed portion 14A of the boot upper.
  • the particular shape of the sealing element 24 should be noted, which as shown in particular in Fig. 9, follows the shape of the longitudinal margin of the edge 22A of the boot upper (or the margin of this edge which defines the front opening of the boot upper); it can also be seen from Figure 8 that a part of that same sealing element 24 extends below the lower horizontal margin of the edge 22A, after having formed the enlarged portion 31.
  • Figures 6 and 6A show a different embodiment of the sealing element, indicated this time with the overall reference 28, this also being shaped so as to follow the shape of the longitudinal margin of the edge 22A (as can be seen in Fig. 10).
  • the anchorage to one of the edges of the boot upper is effected by means of rivets which engage the holes 29.
  • the traditional clip closure levers 26 complete the boot.
  • accessory elements consist of the wrap-around portions 30 and 32 which are fixed externally to the shell at the level of the boot upper in a manner which is known per se (for example by means of rivets 33) and the height of which is adjusted according to the desired height of the lower leg envelopment 20.
  • these wrap-around portions are preferably interchangeable, so as to allow a choice between other wrap-around parts which are lower, higher, harder or softer.
  • an element 32 having the function of permitting limited forward articulation of the upper part 20 of the boot.
  • this element 32 in the form of a shaped insert, is seated in a corresponding recess 42 formed in the body of the upper part of the shell 12 and is equipped on the inner surface (or that turned towards the shell of the boot), with an L-shaped tooth 34 capable of engaging a projection 36 of corresponding and complementary shape, formed on the facing surface of the monobloc.
  • the fixing of the element 32 is completed by a screw 38 which engages an oblong hole 40 and a corresponding hole provided in the body of the shell 12.
  • Figure 4 shows other recesses 46, 48 similar to 42 and which can be accompanied by inserts analogous to that indicated by 32.
  • the sole portion which must be as rigid as possible, there can be carried out the co- injection of a very rigid material resistant to wear and to torsion on the outside which encloses a core of lighter, heat-insulating material.
  • the position of the two materials can be inverted, so that the outer material is more flexible and surrounds an inner core of more rigid material.
