Definitions

  • the present invention concerns a sport footwear, such as a ski boot, or similar footwear, such as a snowboard boot, trekking boot, or an ice-skating boot, provided with a closing mechanism which allows the selective clamping and release thereof.
  • Sport footwear such as ski boots, snowboard boots, trekking boots, or other similar sport footwear, which can be provided with an upper part, or cuff, and a lower part, or shell.
  • the shell can be formed by two lateral portions that, crossing over and overlapping each other, can determine the closure of the ski boot in correspondence with the upper zone of the user's foot or ankle.
  • Shells are also known, formed by two lateral portions configured to determine a front aperture in the upper part of the shell starting from a median zone thereof. Such shells are closed at the front in the tarsal and metatarsal zone of the foot and the tibial zone of the leg by a rigid shaped covering element, also known in the field as tongue.
  • the rigid tongue can be bigger or smaller depending on the specific conformations of the shell and the ski boot, it can also affect the shin zone of the boot and its main function is structural, to support the weight of the user as he/she advances.
  • the rigid tongue has the function of facilitating and simplifying the operations to put on or remove the ski boot before and after use.
  • the rigid tongue is normally rotated toward the outside of the ski boot to allow the user to put it on or take it off more easily.
  • the shell, the upper cuff and the rigid tongue are configured to move in a coordinated way, so as to support both the foot and the leg of the user, optimizing the reaction of the ski boot to the bending and stresses of use.
  • ski boots are also provided with closing mechanisms attached to the shell and/or to the upper cuff, which selectively allow to clamp the ski boot for use during sporting activity, or to release it so that it can be put on or taken off.
  • Each known closing mechanism generally comprises a rack, defined by a series of alternate ridges and grooves and attached near one side of the opening of the ski boot, and an actuation lever attached near the opposite side of the opening of the ski boot with respect to the side where the rack is attached.
  • the actuation lever is provided with one or more pegs suitable to cooperate with one or more of the grooves of the rack, chosen by the user, in order to obtain the clamping of the closing mechanism and the consequent closing of the opening of the shell by bringing together the two sides described above.
  • the closing force depends on the groove of the rack in which the user puts the one or more pins of the actuation lever, according to his/her requirements.
  • the user is able to make an adjustment of the mechanical hold and rigidity of the ski boot during the sporting activity.
  • the greatest closing force is normally applied to the closing mechanism closest to the front part of the shell, that is, the closing mechanism that during use surrounds the metatarsal zone of the user's foot.
  • ski boots One disadvantage of known ski boots is that, once the closing mechanisms have been released or loosened, for example during a pause in the sporting activity, it is difficult to restore, upon restarting the activity, the desired adjustment of the mechanical hold and rigidity of the ski boots. The difficulty is greatest in correspondence with the closing mechanisms subjected to the greatest closing force.
  • Known ski boots in which the shell has the front aperture have the disadvantage that they have a front terminal portion, that is, the portion of the shell that surrounds the zone of the user's toes, which is rigid, and hence cannot be adjusted by closing mechanisms.
  • ski boots Another disadvantage of known ski boots is the difficulty that a user can find, whether an expert or not, in putting on and/or removing the boots, which difficulty is caused particularly by the fact that their structure is, and must be, mainly rigid and solid, taking into account the activities it must perform.
  • U.S. Pat. No. 3,722,122 describes a known ski boot that provides a shell which can be closed using closing systems with levers.
  • the shell can have at the front part a short V-shaped notched portion, in a central and symmetrical position with respect to a longitudinal median axis of the boot, which is provided to prevent the bending and deformation under stress of the material when the boot is closed.
  • closing systems with levers do not overlap the short V-shaped notched portion, but are provided only astride the front aperture of the shell and therefore would not have any effect in possibly varying and adjusting the volume of the rigid front part of the ski boot, since they would only bring together the lateral edges of the front aperture of the shell.
  • one purpose of the present invention is to obtain a ski boot or other similar sport boot, which can be adjusted and closed with a desired closing force also in the front end zone and which allows to obtain a desired adjustment of the mechanical hold and rigidity of the ski boot easily restorable even after the sporting activity has been suspended.
  • Another purpose of the present invention is to obtain a ski boot or similar sport boot which is easy to use and at the same time allows to simplify and facilitate the operations to put on and take off the ski boot.
  • the Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.
  • a sport footwear such as a ski boot, or similar sport footwear, made according to the present invention, comprises at least a rigid shell which has a front aperture, a front point and a front end portion, comprised between the front aperture and the point along a longitudinal median axis of development of the shell.
  • the sport footwear comprises a weakening notch or slit with an elongated shape, made through in the front end portion of the shell and configured to allow a volumetric variation of the shell at least in correspondence to the front end portion.
  • the weakening notch has an open profile communicating with the front aperture, of which it defines a terminal appendix, while alternative solutions provide that the weakening notch has a closed profile and is separate from the front aperture.
  • the weakening notch is delimited by reciprocally adjacent or overlapping edges.
  • the sport footwear comprises tie-rod, for example a front terminal closing mechanism, associated at the upper part to the weakening notch in order to define the desired volumetric variation, in particular acting in traction in a direction transverse to the longitudinal median axis.
  • tie-rod for example a front terminal closing mechanism, associated at the upper part to the weakening notch in order to define the desired volumetric variation, in particular acting in traction in a direction transverse to the longitudinal median axis.
  • the front terminal closing mechanism is provided in the front end portion in correspondence to the weakening notch, in particular overlapping it, that is, above and transversely astride it.
  • the front terminal closing mechanism can be attached to lateral portions of the shell that laterally delimit the front aperture and can be configured to assume at least an unclamped condition and a clamped condition that brings together the lateral portions.
  • the weakening notch is inclined with respect to the longitudinal median axis.
  • the weakening notch is at the side of the longitudinal median axis, that is, not aligned with the longitudinal median axis, or rather it is not central.
  • the weakening notch can be provided on the internal side or on the external side of the boot, whether it is the right one or the left.
  • providing the weakening notch laterally allows a better closing of the boot, since it prevents the generation of localized pressure points on the user's foot, since it advantageously takes into account the typical conformation of the foot, which is not symmetrical but develops differently between the outside and the inside.
  • the lateral weakening notch adapts favorably to the non-symmetrical morphology of the foot, allowing the user to put on the boot comfortably, which does not generate painful local pressures.
  • this lateral position of the weakening notch that even if the boot is closed hard, it does not generate deformations of the material of the front portion of the shell during closing, which can for example cause deformations protruding toward the inside of the boot and cause painful pressures on the toes or the foot in general.
  • the weakening notch is delimited by reciprocally adjacent or overlapping edges.
  • the front terminal closing mechanism comprises two elements which can be reciprocally brought together, and the shell comprises a support band or platelet for one of said elements, made in a single piece with one of the lateral portions of the shell in correspondence to one of the edges.
  • the support band allows to anchor the closing of the boot in a wraparound and uniform way around the foot, contributing to prevent forming deformations of the material and painful pressure points on the foot.
  • the sport footwear can comprise a rigid or semi-rigid covering member attached to the front end portion of the shell and provided with a first lower segment configured to irremovably cover the front end portion, and with a second upper segment, hinged to the first lower segment and configured to selectively assume a closed condition, to cover the front aperture, and an open condition in which it is rotated toward the front end portion with respect to the front aperture.

  • the shell 20 has an overall “L” shape, coordinated with the part of the foot and the leg comprised between the knee and the malleolar part to be surrounded and contained.
  • the shell 20 can be made by a production process of molding for example.
  • an upper part or upper cuff 60 can be provided, which is also rigid, and configured to reinforce the ski boot 10 in its rear and/or front part.
  • the upper cuff 60 can be pivoted on the shell 20 substantially in correspondence to the zone in which the user's ankle joint will be disposed during use, so that the upper cuff 60 can, when required, incline with respect to the shell 20 .
  • the shell 20 is configured to contain the user's foot and ankle, and that the upper cuff 60 is configured to contain the part of the leg comprised between the malleolar zone and the knee.
  • the shell 20 generally develops along a longitudinal median axis or direction X, between a front point or toe-box 24 and a heel 29 and can include a front end portion 22 , that delimits a front terminal volume 23 of the internal compartment 21 comprised between the toe-box 24 of the shell 20 and the part of the latter which, during use, contains the user's metatarsal zone and toes.
  • the shell 20 can include two lateral portions 25 a , 25 b , that delimit from opposite sides a front aperture 26 which affects the shell 20 at the front from the upper end of the latter as far as the front end portion 22 .
  • the front aperture 26 is configured to facilitate the insertion and extraction of the user's foot into and out of the internal compartment 21 of the shell 20 , in particular putting the internal compartment 21 into direct communication with the outside during the operations to put on and take off the ski boot 10 .

  • the ski boot 10 can include a plurality of closing mechanisms 30 , configured to determine the closing and adjustment of the rigidity, and therefore the clamping and solid grip around the user's leg and foot.
  • This adjustment of the rigidity made by the closing mechanisms 30 can provide, in a known way, in the upper and front parts of the shell 20 ( FIG. 1 ), to bring its lateral portions 25 a and 25 b reciprocally nearer, toward the inside of the front aperture 26 .
  • the closing mechanisms 30 can also be configured to contact the tongue 40 and the upper cuff 60 when closed or clamped, and maintain the covering of the front aperture 26 , as well as adjust the rigidity of the ski boot 10 .

  • the weakening notch 27 is configured to define a weakening of the structure of the shell 20 in correspondence to the front end portion 22 . This allows to modify the front terminal volume 23 delimited by said front end portion 22 , and therefore a volumetric adjustment desired by the user, by a front terminal closing mechanism 30 a , for which some forms of embodiment are described in FIG. 3 .
  • the front terminal closing mechanism 30 a ( FIGS. 1 and 3 ) can be attached to the front end portion 22 of the shell 20 in correspondence to the weakening notch 27 and overlapping the same, that is, above and transversely astride the latter.
