Definitions

  • the present invention relates to a sports shoe, particularly a ski boot or a skate.
  • Conventional ski boots may be constituted by a shell and by at least one quarter made of very rigid plastics, so as to allow to protect the foot and the lower part of the leg against accidental impacts and to allow the anchoring of levers that are subjected to considerable tensions imparted to them during fastening and during sports practice, and also allow the transmission of forces from the foot to the sports implement.
  • a ski boot has been proposed, which is marketed by the Rossignol company under the trademark SOFT1 and is constituted by a rigid shell that laterally surrounds the foot of the user and part of the lower region of the leg of the user and has an upper opening.
  • a quarter is pivoted to the rigid shell; the quarter also is rigid and laterally surrounds the leg of the user.
  • the ends of closure levers are associated with the flaps of the quarter and the shell. Also, the shell is overmolded at an additional upper.
  • An upper with soft overlapping flaps is associated at the upper open region of the shell, and a soft innerboot can be arranged inside the quarter and the shell.
  • the bands that constitute the levers rest directly at the underlying soft flaps: this entails difficulty in the mutual sliding of the two materials and therefore the discomfort for the user increases when the levers are fastened and when they are further tensioned during sports practice.
  • the forces transmitted directly to the metatarsal region, to the instep region and to the front part of the tibia are such as to produce localized pressure regions that decrease user comfort.
  • the aim of the present invention is to solve the drawbacks noted above and solve the described technical problems by providing a sports shoe, such as a ski boot or a skate, that allows to achieve optimum transmission of the forces of the foot to the sports implement, allows optimum anchoring of the levers, and allows the user to achieve a high degree of comfort both when putting on the shoe and during sports practice.
  • a sports shoe such as a ski boot or a skate
  • An object is to provide a sports shoe that has a low weight.
  • a further object is to provide a sports shoe that has low manufacturing costs by limiting the use of high-rigidity materials.
  • a further object is to provide a sports shoe in which the fastening of the levers does not cause localized pressures in the metatarsal and instep regions of the foot or in the front part of the tibia of the user's leg.
  • the reference numeral 1 designates a sports shoe, particularly a ski boot, which is constituted by a rigid box-like shell 2.
  • the shell is produced for example by injecting thermoplastic material with thicknesses 3 whose dimensions are comparable to those of conventional ski boot shells.
  • the box-like shell 2 includes a lower sole 4 of a standardized type, from which a perimetric ridge 5 protrudes.
  • the ridge laterally surrounds part of the foot of the user and therefore has a limited height with respect to the surface on which the sole rests on the ski.
  • Counters 8a and 8b are provided at a heel region 6 and at a toe region 7; the first counter is directed toward the heel region 6, and a first tongue 9 is hinged thereto.
  • the tongue is as rigid as the box-like shell and lies longitudinally in the direction of the region 6 of the heel, so as to affect a region 10 of the user's foot instep.
  • a first tab 11 and a second tab 12 protrude from the perimetric ridge 5, transversely to the box-like shell 2 and at a chosen point of the foot instep region 10.
  • the first tab 11 has such an extension as to affect at least the entire height of the lateral edge of the foot of the user, optionally partially surmounting it, while the second tab 12 surrounds, in an upper region, the first tongue 9, which is rigid, affecting it totally or partially.
  • the first and second tabs may have the same rigidity of the box-like shell and can be separate from the shell and associated therewith.
  • the second tab 12 is substantially shaped like a letter Y, in which first wings 13a, 13b are connected to the perimetric ridge 5 in regions that are approximately adjacent to the plantar arch region, on the opposite side with respect to the first tab, so as to allow a better and optimum distribution of the forces when fastening a first lever 14 adapted to mutually fasten the first and second tabs.
  • the sports shoe also comprises a semirigid secondary shell 15, which is also made for example of thermoplastic material but is not as thick as the box-like shell 2, so as to be less rigid.
  • the secondary shell 15 surrounds the entire foot of the user, except for the foot instep region 10, where there is an opening 16.
  • the secondary shell 15 surrounds the entire malleolar region 17 and partially surrounds the rear-lateral region of the leg of the user.
  • Two second tongues 18a and 18b can be positioned at the opening 16 and are associated with the secondary shell 15.
  • the flaps are made of a material that is soft and therefore suitable to increase user comfort.
  • the two second tongues 18a and 18b are associated by riveting, gluing or overmolding at the edges formed by the opening 16 in the secondary shell 15.
  • the shoe also comprises a semirigid cuff 19 which is approximately as rigid as the secondary shell 15, which is articulated thereto by means of rivets, or other fasteners, at the malleolar region 17.
  • the cuff 19 is open at the front.
  • a soft outer covering 20 is associated with the secondary shell 15 and with the cuff 19.
  • the covering 20 is provided by means of fabric or other soft material.
  • the covering 20 can be obtained by gluing and/or sewing it, in one or more pieces, directly to the secondary shell and to the cuff.
  • the resulting structure can be inserted at the box-like shell 2, so as to thus obtain the shoe 1.
  • a second lever 21 which is arranged in the foot instep region so that its ends are associated for example at the studs for the pivoting of the secondary shell 15 to the cuff 19.
  • a third lever 22 which is identical to the first lever 14 and therefore is again Y-shaped so as to form second wings 23a and 23b which mutually diverge and are associable with the free ends for example at the cuff 19 by means of appropriate rivets or fixing elements.
  • a usual known soft innerboot 24 can then be inserted in the structure thus obtained.
  • the shoe thus obtained has a low weight and reduced manufacturing costs, because the use of highly rigid materials is limited.
  • the shoe not only allows optimum connection of the levers thereto but also allows to avoid producing localized pressures in the metatarsal and instep regions of the foot or at the front region of the tibia of the user's leg.
  • the materials and the shape or the dimensions of the individual components of the shoes may of course be the most pertinent and disparate according to specific requirements.
