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 means of 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.
  • Document US-A-3,722,112 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 means, 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 means 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 means 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 comprises 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.
  • Fig. 1 is used to describe forms of embodiment of a sport footwear, such as a ski boot, or similar sport footwear, according to the present invention, indicated in its entirety by the reference number 10.
  • the ski boot 10 can be provided with a containing body, or shell 20, made of a rigid plastic or composite material and configured to contain, inside its own internal compartment 21, both the user's foot and part of the leg comprised between the malleolar zone and the knee.
  • 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 productive 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 includes two lateral portions 25a, 25b, 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 front aperture 26 can be delimited by an open profile that can be essentially U-shaped.
  • the front aperture 26 develops along an essentially L-shaped surface, coordinated with an overall L-shape of the combination of the shell 20 and upper cuff 60.
  • a rigid or semi-rigid covering member such as a tongue 40, can be provided to completely cover the front aperture 26 in order to close the ski boot 10 and confer structural rigidity and resistance on it during use.
  • the tongue 40 can be selectively removable, even partly, in order to allow the user to put on and take off the ski boot 10 more easily.
  • the ski boot 10 includes 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 25a and 25b 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 closing mechanisms 30 allow to reduce pressure on the upper cuff 60 and/or the tongue 40, allowing the user to walk more easily, or to take off or put on the ski boot 10 more easily.
  • Figs. 1 and 2 are used to describe the shell 20, in which, in the upper part of the front end portion 22, a weakening notch 27 is made, positioned between the front aperture 26 and the toe-box 24 and delimited by two lateral edges 28 each forming part of a respective lateral portion 25a, or 25b.
  • the weakening notch 27 has an elongated shape.
  • the weakening notch 27 can extend essentially in a direction coincident or substantially parallel to the longitudinal median axis X of development of the part of the shell 20 comprised between toe-box 24 and heel 29 and intended to contain the user's foot during use.
  • the weakening notch 27 can have a rectilinear or curvilinear development, or along a broken or mixed line, and can have a longitudinal section which is rectangular, triangular or any other regular or irregular shape, even oblong, according to the invention oriented in a direction inclined or transverse to it, in particular lateral, that is, not centered.
  • the present invention provides that the weakening notch is inclined with respect to the longitudinal median axis X.
  • the weakening notch 27 is at the side of the longitudinal median axis X.
  • the weakening notch 27 is in a non-symmetrical position with respect to the longitudinal median axis X.
  • the lateral or in any case non-symmetrical positioning of the weakening notch 27 can allow a better closure, without pressure points on the foot or toes, since the lateral disposition adapts very well to the non-symmetrical conformation typical of the foot. Moreover, even if the boot 10 is closed hard, this does not generate deformations of the material of the shell 20 and prevents further painful pressure for the user.
  • a plurality of weakening notches 27 can be provided, depending on the specific requirements of the producer of the ski boot 10 or of the user.
  • figs. 1 and 2 are used to describe forms of embodiment, which can be combined with all the forms of embodiment described here, of a weakening notch 27, substantially wedge-shaped and converging toward the toe-box 24 of the shell 20.
  • the two lateral edges which delimit the weakening notch 27 can be convergent with respect to each other, toward the toe-box 24 of the shell 20, defining, for example, a V-shaped configuration, like an elongated nose, advantageously at the side of the longitudinal median axis X and inclined, or slightly inclined, with respect thereto, that is, non-symmetrical with respect to the longitudinal median axis X.
  • the weakening notch 27 has an open profile and communicates with the front aperture 26, of which it substantially defines a terminal appendix, but this does not exclude possible embodiments in which the weakening notch 27 can have a closed profile and therefore be separate from the front aperture 26.
  • 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 means of a front terminal closing mechanism 30a, for which some forms of embodiment are described in fig. 3 .
  • the front terminal closing mechanism 30a ( 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.
  • the front terminal closing mechanism 30a acts as a tie-rod mean and is configured to selectively determine the reciprocal bringing together or distancing of the lateral edges 28, as will be clear hereafter.
  • the front terminal closing mechanism 30a in the specific example shown in fig. 3 , includes a rack 31, defined by a series of ridges 31a and grooves 31b, reciprocally alternate, and attached to a lateral portion 25a, or 25b of the shell 20.
  • the front terminal closing element 30a can also include an actuation lever 32 attached to the other lateral portion 25b, or 25a, with respect to the one to which the rack 31 is attached.
  • the actuation lever 32 can cooperate with the rack 31 to achieve the selective clamping of the front terminal closing mechanism 30a.
  • the clamping provides that the driving of the actuation lever 32 determines a desired closing force to which a determinate bringing together or distancing of the lateral portions 25a and 25b, and consequently of the lateral edges 28, corresponds.
  • the bringing together or distancing of the lateral edges 28 determines a variation in the front terminal volume 23.
  • the weakening notch 27 can be configured so that the lateral edges 28 are reciprocally overlapping, or can be overlapping, when the actuation lever 32 is driven.
  • one or more variants of closing mechanisms 30 can be provided.
  • figs. 4a and 4b are also used to describe forms of embodiment and variants of the front terminal closing mechanism 30a alone, indicated respectively with the reference numbers 130a and 230a.
  • the front terminal closing mechanism 130a in fig. 4a includes a screw regulator 33, instead of the rack 31 and the actuation lever 32.
  • the screw regulator 33 can be provided with two threaded elements, for example a pin 35 threaded externally and positioned inside a bushing 36 threaded internally, configured to move reciprocally after the screwing or unscrewing of one of them, for example of the bushing 36.
  • the pin 35 and the bushing 36 can each be attached or connected to one of the lateral portions 25a and 25b, determining, after the screwing or unscrewing thereof, respectively the bringing together or distancing of the lateral edges 28.
  • FIG. 34 can include a protection lever 34, which surrounds the screw regulator 33 to protect it from any possible knocks or damage that could compromise its functionality.
  • the screw regulator 33 can include reciprocally engaging toothed members, such as for example a worm screw which acts on a pair of racks, each solid to a lateral portion 25a, 25b.
  • the variant terminal closing mechanism 230a includes a rack 31 that, unlike what has been described heretofore, is attached to a support band or platelet 37 made for example by molding, in a single piece with the shell 20.
  • Figs. 4b and 5 are used to describe forms of embodiment, which can be combined with all the forms of embodiment described here, of the support band 37 positioned in the front end portion 22 near the weakening notch 27.
  • the weakening notch 27 can have an arched oblong shape with the function of limiting the stresses acting on the lateral edges 28 because of the effect of the closing force exerted by the front terminal closing mechanism 30a, 130a, 230a.
  • this configuration can be intended to allow one lateral edge 28 to overlap over the other during the clamping of the front terminal closing mechanism 30a.
  • the tongue 40 can be divided into a first lower segment 41, positioned as upper covering of the front end portion 22 of the shell 20, and a second upper segment 42, positioned to cover the front aperture 26 in the remaining part of the shell 20.
  • tongue 40 which can also be in a single piece, or divided into more than two segments, the latter for example to facilitate the user in walking when the closing mechanisms 30 are loosened or unclamped.
