Definitions

  • the present invention relates to a sports boot, such as a ski boot or, in general, an item of sports footgear such as a skate.
  • the shell is generally manufactured with high-quality material, such as for example polyurethane, because it must be very rigid, so as to allow optimum transmission of efforts from the foot to the ski, and it also must be highly resistant to abrasion in order to reduce the wear due to coupling to the binding and to interaction with the ground while walking.
  • high-quality material such as for example polyurethane
  • the shell also has at least one quarter, also made of high-quality material and thus having a high degree of rigidity.
  • Italian patent no. 858508 filed on February 26, 1969 discloses a method for manufacturing ski footgear in which a rigid thermoplastic material is injected into a mold to form, with said material, only the lower part of the item of footgear, which is joined to the upper part, made of soft and semi-elastic material, by means of a welding with penetration of the materials along the joining line.
  • EP-A-484 845 discloses a conventional ski boot as defined in the preamble of the appended claim 1.
  • the aim of the present invention is to eliminate the problems described above in conventional boots by providing a boot which allows the user to optimally transmit efforts at the ski, or at the wheels of the skate, and at the same time allows to achieve an optimum condition of comfort, also providing an easy insertion of the foot.
  • an important object is to provide a boot wherein the use of high-quality and therefore rigid material is extremely limited, thus allowing to provide a product having a low cost, conversely, allowing to provide a stiffer boot by using conveniently rigid materials for boot of highly technical characteristics, for example for competitions.
  • Another important object is to provide a boot which is reliable and safe in use and can be manufactured with conventional equipment.
  • a further object is to provide a boot which is structurally simple and easy to apply.
  • the reference numeral 1 designates a flap applied to a sports boot 2 which is constituted by at least one quarter 4 associated to a shell 3.
  • the illustrated examples show in particular a ski boot.
  • a longitudinal depression 6 is formed on the shell 3 at the upper metatarsal region 5.
  • the quarter 4 instead embraces the skier's leg to the rear and has an opening 8 at the front region 7.
  • Both the quarter 4 and the shell 3 may be made of a traditional high quality material, such as polyurethane, or of a material which is not of extremely high quality, such as for example polypropylene, having a smaller degree of rigidity and resistance to abrasion than other materials, such as polyurethane, usually used in the prior art to obtain the shell and the quarter.
  • a traditional high quality material such as polyurethane
  • a material which is not of extremely high quality such as for example polypropylene, having a smaller degree of rigidity and resistance to abrasion than other materials, such as polyurethane, usually used in the prior art to obtain the shell and the quarter.
  • each flap comprises a first rigid element, designated by the reference numerals 9a, 9b, 9c and 9d, and a second soft element, designated by the reference numerals 10a, 10b, 10c and 10d.
  • the external lateral side of the boot may be provided with a flap as described above, as in the illustrated embodiment, or may be provided with a simple flap constituted by a single element formed integrally with or associated with the quarter or shell.
  • the first rigid elements 9a, 9b, 9c and 9d respectively affect the lateral regions 11a and 11b of the user's leg and the lateral regions 12a and 12b of his foot.
  • the first rigid elements can be connected, in a fixed or removable manner, respectively to the quarter 4 and to the shell 3.
  • adapted first seats 13 and second seats 14 are formed on the quarter and shell.
  • Complementarily shaped first engagement means 15 and second engagement means 16, which are associated approximately at the perimetric edges of the first rigid elements, can be associated with seats 13 and 14.
  • the second soft elements 10a, 10b, 10c and 10d are associated with the first rigid elements, for example by glueing, electric welding or by means of rivets, and affect the front region 7 of the leg and the upper metatarsal region 5, partially overlapping one another.
  • Means for mutually securing the quarter and the shell, such as adapted levers 20, can furthermore be applied to the first rigid elements and to the second soft elements.
  • the flap comprises a first rigid element, which affects at least the lateral inner region of the foot or of the leg, and a second soft element, which affects the upper metatarsal region or the tibial region.
  • the shell and quarter can be made either of a material having low strength characteristics and thus of lower quality, allowing for a considerable containment of costs, or of a traditional material of higher technical characteristics, such as polyurethane, for obtaining a stiffening of the lateral regions, particularly of the inner lateral region of the boot for a high performance boot.
  • the presence of the first rigid elements at least at the lateral inner regions of the shell and of the quarter allows optimum transmission of the efforts from the leg and from the foot to the ski, for an improved performance, thus obtaining a boot having regions which are more or less rigid according to the specific requirements.
  • the presence of the second soft elements allows to easily insert the foot in the boot and subsequently remove it even at low temperatures.
  • the invention has achieved the intended aim and objects, a flap having been obtained which allows to provide a boot by means of material having low strength characteristics and thus not extremely rigid, the first rigid elements in any case ensuring the rigidity required to ensure lateral support, or to provide a boot with traditional high quality materials with improved technical characteristics for an improved performance.
  • the use of the second soft elements allows to increase comfort for the user.
  • a boot is thus technically provided having more or less rigid regions located in the points where it is technically and functionally necessary to differentiate said degree of rigidity.
