    DESCRIPTION "SKI SHOE WITH SKI-WALK MECHANISM TO FRONTSIDE"
    FIELD OF THE INVENTION
    The present invention relates to a ski boot provided with a mechanism for selecting from
    Ski configuration is provided to the Gehkonfiguration, which is usually referred to as Ski-Walk and is located at a position on the front.
    STATE OF THE ART
    As is known, ski boots comprise a shell adapted to receive the foot of the user and a cuff adapted to receive the user's tibia portion which are at least partially open to permit the foot to be imported. The subsequent closing of the shell and the cuff via a plurality of buckles closure, which are provided with hooks which hook into ratchet teeth, which are conveniently positioned on the shoe. Moreover, it is known to export some types of ski boots for ski touring activities, which are intended to provide the skier with a ski configuration in which the cuff must be rigid relative to the shell, with extreme precision on the shoe and the foot thus transferring the ski, may proceed to a walking configuration in which the shoe must allow maximum possible rotation of the cuff with respect to the shell to assist the rotational movement of the foot during walking of the user.
    The transition from one configuration to another can also be done very often, especially when the user is transitioning from groomed slopes to off-piste trails and therefore has to constantly alternate between ski trail sections and walkway sections.
    Generally these ski boot types are used in disciplines like telemark ski touring and the like.
    The ski boot solutions known in the prior art provide for the construction of a cuff articulated on the shell for rotation about a pivot axis positioned near the ankles and a ski / walking selection. or ski-walk mechanism capable of preventing or allowing the rotation of the cuff with respect to the shell.
    Such a mechanism of the known type usually comprises a rod which is hinged to the shell and provided with a free end adapted to selectively engage with a hook or similar device which conveniently engages the collar is attached. In case of locking the end prevents the
    Bar any relative movement and thus any translational movement between the cuff and the shell, serving essentially both as a support and as a tension rod.
    The known solutions are not free of disadvantages and limitations.
    Above all, the known solutions provide rods which, together with the corresponding locking / unlocking mechanisms, comprise buckles or snaps which have to be actuated for the transition between configurations, are arranged at the rear of the shell and on the sleeve.
    Such buckles and devices are, in view of the fact that they are located at the rear of the boot, difficult to access: the user thus has to bend down and run his hand on the rear side of the shoe, not even the handle to be taken and operated buckle sees.
    The recognition and operation of these devices are thus complicated and inconvenient, considering also the fact that the user must be able to operate them with donning lined gloves. Moreover, the devices must also ensure that there are no relative movements between the cuff and the shell in the ski configuration: in other words, the latch / unlock mechanism must be able to substantially lock the cuff, with the possibility of minimal play must be prevented. Otherwise, the user would lose sensitivity and the ski boot would be imprecise when skiing.
    On the other hand, the same device must be able to counteract in the walking configuration the rotational movement of the sleeve with respect to the shell as little as possible. In this way, easy and less tiring walking is possible.
    The two requirements are therefore contradictory. In fact, the known solutions of the prior art provide for the use of rods that intermesh with pivot pins; such rods used to stiffen the latch, even when unlocked, involve considerable friction with parts of the ski boot which act as a guide therefor.
    The above-mentioned problems are by no means negligible, especially considering that over a day several dozen times may be required to enable / disable the device.
    Therefore, it can be understood that the technical task of the present invention is highly understandable among users.

    There is thus a need to solve the disadvantages and limitations mentioned in relation to the known state of the art.
    This need is met with a ski boot according to claim 1.

    DETAILED DESCRIPTION
    With reference to the preceding figures, there is shown generally at 4 an overall schematic view of a ski boot according to the present invention.
    It should be noted that the term ski boot for the purposes of the present invention is to be interpreted in a broad sense and includes any type of ski boot for ski touring, telemark and the like.
    The ski boot 4 comprises a shell 8 adapted to receive the foot of a user and a cuff 12 connected to the shell 8 and adapted to receive a shin portion of a user.
    For purposes of the present invention, both the shell 8 and the collar 12 may have any dimension, shape, and any material, and be of any type including, for example, two or more assembled or hinged parts.
    The cuff 12 is articulated to the shell 8 in the region of a pair of joints 14 in the area of the ankle of the user.
    The cuff 12 includes a pair of side flaps 16, 18 that overlap at least partially in the region of a front portion 20 of the cuff 12 that extends to a tip 24 of the shell 8.
    The shell 8 in turn comprises a pair of lower flaps 26, 28 which at least partially extend towards each other and / or overlap one another.
    The shoe 4 further comprises a tongue 32 which at least partially overlaps the side flaps 16, 18 in the region of the front portion 20 of the cuff 12.
    The tongue also at least partially overlaps the lower flaps 26, 28 of the shell 8 in the region of a back portion 36 of the shell.
    The tongue 32 comprises a pair of regions, with a first region 40 forming an interface with the front portion 20 of the collar 12, a second region 44 forming an interface with a back portion 36 of the shell 8, between the first and second regions 40, 44 Joint means 48 are interposed, which are adapted to allow a relative rotation between the first and the second region 40, 44.
    The term joint means 48 is to be understood in the broadest sense and not literally.
    In particular, it is possible to provide that the hinge means 48 comprise an elastically deformable portion 52. For example, the elastically deformable portion 52 may include a bellows-type portion. In this case, the bellows-like portion does not form a joint in the true sense, since no precise geometric axis of rotation can be determined, since the rotation takes place in the region of the elastically deformable part. In any event, the bellows-like portion performs the hinge function, allowing relative rotation between the first and second regions 44. The deformation is elastic in the sense that when the thrust ends on at least one of the regions, the bellows-like portion or equivalent elastically deformable portion 52 elastically returns to its own undeformed configuration without undergoing permanent or plastic deformation.
    According to another possible embodiment, the hinge means 48 comprise joints with corresponding pivot pins (not shown).
    Mixed embodiments are also possible in which the hinge means 48 comprise both an elastically deformable portion 52, which is provided, for example, with a bellows-type portion, and one or more pivot pins.
    The second region 44 of the tongue 32 is in turn articulated on the back of the shell 8 on the opposite side of the hinge means 48. Advantageously, the tongue 32 is provided with ski-walk selection means 56 to permit a ski configuration in which the ski-walk selection means 56 rigidly fix the first and second regions 40, 44 between them, thereby preventing the mutual rotation a walking configuration in which the ski walk selection means 56 allow the relative rotation between the first and the second region 40, 44.
    Preferably, the ski-walk selection means 56 provide a restriction on double-sided rotation between the first region 40 and the second region 44 such that any rotation between the regions 40, 44 is prevented for both approach and removal.
    Preferably, the ski walk selection means 56 are arranged on, or over, the hinge means 48 sitting.
    According to one embodiment, the ski walk selection means 56 comprise at least one hook 60 and at least one tooth 64 adapted to couple with the hook 60 to interlock the first and second regions 40, 44 with each other, the hook 60 and the tooth 64 are each arranged on a corresponding region 40, 44 of the tongue 32.
    In other words, the hook 6 0 and the tooth 64 are equally fixed on which of the various regions 40, 44: Thus, the corresponding positions on the regions are equivalent for the purpose of the present invention.
    The tooth 64 may for example consist of a simple pin on which the hook 60 engages.
    In particular, the hook 60 is hinged to a corresponding area 40, 44 such that it rotates from an unlatching configuration in which it is disengaged from the tooth 64 to a locking configuration in which it locates on the other area 44, 40 to hook into the corresponding tooth 64.
    Preferably, the hook 60 is hinged to a first pivot pin 61 to move from the latch or skid configuration to the unlatch or pivot
    To be able to go to Gehkonfiguration by turning around the corresponding first pivot pin 61 around. Preferably, the fuse 68 is pivotally mounted on a second pivot pin 63 to from the
    Locking configuration of the hook 60 in the unlocking configuration of the hook 60 to be able to go around by turning around the corresponding second pivot pin 63 around.
    The coupling between the hook 60 and the tooth 64 is preferably of the frictional type, i. with excess, but can also be free.
    Preferably, the ski walk selection means 56 includes a fuse 68 adapted to lock the hook 60 in place as it engages the corresponding tooth 64.
    The second region 44 is articulated to the back portion 36 of the shell 8 near a tip 24 of the shoe 4 by means of a pair of pivot pins 72 connected to lateral portions 76, 78 of the shell 8.
    In one embodiment, the tongue 32 includes a reinforcing plate 80 that extends from the pivot pins 72 to ski walk selection means 56.
    The cuff 12 includes closure means 84 which include buckles 88 which are operably connected in a known manner to rings 90 and corresponding detents 92 which, in the closure configuration, allow closure between the side flaps 16, 18.
    Preferably, the closure means 84 are positioned in a manner to overlap the first portion 40 of the tongue 32 in the closure configuration of the same closure means 84.
    In this way, upon closure of the closure means 84 on the sleeve 12, a restriction on the rotation of the tongue 32 is obtained. It is clear that when the closure means 84 on the cuff 12 are closed and the ski-walk selection means 56 are in the skiing position, a maximum possible rigidity of the shoe 4 is obtained. In the closed configuration of the closure means 84 on the cuff 12, when the unlocking of the ski walk selection means 56 to the walk or walk position is performed, the tongue 32 will be able to flex forward, thus controlling the walking movement even partially, to support. It will be understood that maximum walking deflection and thus maximum deflection of the user's leg will be possible in the opened configuration of the closure means 84 on the cuff 12 and the walk position of the ski walk selection means 56.
    According to one embodiment, the closure means 84 of the cuff 12 are positioned to at least partially overlap the ski-walk selection means 56 to prevent the release of the ski-walk selection means 56 in the closed configuration of the closure means 84. This embodiment provides additional security since it prevents the unlocking of the ski walk selection means 56 as long as the closure means 84 are closed.
    According to one embodiment, the shell 8 comprises closure means 84 comprising buckles 88 which are operatively connected to rings 90 and corresponding detents 92 which, in the closed configuration, allow closure between the lower flaps 26, 28 with the closure means 84 in the closed position Configuration of the closure means 84 are positioned so that they at least partially overlap the second portion 44 of the tongue 32.
    According to one embodiment, the shell 8 comprises closure means 84 comprising buckles 88 operable with rings 90 and corresponding ones
    Latching latches 92 which, in the closed configuration, allow the closure between the lower flaps 26, 28, the closure means 84 being positioned so as to at least partially overlap the ski-walk selection means 56 in order to unlock the ski-walkway. Selection means 56 in the closed configuration of the closure means 84 to prevent.
    As is apparent from the description, the ski boot according to the invention makes it possible to overcome the disadvantages set forth in the known prior art. In particular, thanks to the present invention, the rear ski-walk mechanism, which is present in all footwear on the market for use in the telemark ski touring disciplines, is completely eliminated.
    In this way, especially the security for the user is increased. In fact, the selector mechanism located at the front of the tongue is located in a sheltered place that is less impacted. In fact, in the event of a fall, the rear or lateral part of the cuff or shell is likely to be subject to more impacts and certainly not the anterior part near the hinge of the tongue near the junction of the tibial component and the back of the foot. Moreover, the ski-walk mechanism in the frontal position can be easily controlled by the user, it is easily accessible and easier to use compared to the known solutions, since it is arranged at a position that is always visible to the user who can easily recognize and operate him, even with gloves on. Moreover, the ski-walk mechanism of the present invention in the locked or ski configuration is extremely rigid and thus also very precise in transmitting the user's movements to the shoe. Thus, in the ski configuration, the shoe has a rigidity more than adequate to meet the requirements of a skier in terms of reliability and skiing precision.
    At the same time, the mechanism of the present invention in the Walk position is capable of
    Releasing rotational movement of the cuff with respect to the shell without in any way inhibiting or counteracting the rotation of the cuff and thus without increasing the effort on the part of the user when walking. Moreover, the present invention is also characterized by the ease of walking even with closed buckles: in fact, by unlocking the ski
    Walk mechanism even with closed buckles a deflection of the cuff in relation to the shell possible. Thus, it is possible to go with both fully open buckles and closed buckles. Moreover, the implementation of the solution of the present invention is particularly economical: in fact, the mechanism itself is completely housed in the tongue.
    Theoretically, it is also possible to use the present invention as a retrofit: the original tongue could be replaced with one provided with a hinge and a corresponding ski-walk mechanism to allow the walking movement of a shoe that was not originally intended for this use is designed. Moreover, the solution of the present invention is more economical than the known solutions because, as mentioned, it is concentrated on the tongue in the forward position.
    This lower cost is thus due to the simplicity of the ski-walk mechanism on the tongue, which can eliminate some of the components and mechanisms used in the known solutions, which are mechanically more complex. Moreover, thanks to the present invention, the
    In fact, the articulation on the tongue can be advantageously used to increase the insertion opening for the foot, and thus to simplify dressing, by simply unfolding the tongue forward as the shoe is tightened. Moreover, unlike the solutions of the prior art, the angle of inclination of the shoe during skiing is always the same for each leg / calf dimension, as it is determined by the front mechanism on the tongue in the skiing position, as the rear cuff will rotate freely and independently and can adapt to the calf dimension. It is actually known that, given the same size, the caliper diameters may vary on average by plus or minus about 6 cm.
    This may not be the case with back-to-back shoes where leg tilt is changed: in fact, the known solutions often use a removable spoiler with a maximum thickness of one centimeter to try to improve this situation.
    Thanks to the present invention, the problem is solved in advance. Moreover, thanks to the simplicity and smaller number of components of the final product, the present shoe has better fatigue resistance.
    In sum, the present invention makes it possible to obtain a very technical shoe characterized by the resistance of the angle of inclination of the sleeve with respect to the shell, the blocking of the protrusion and the ease of insertion and extraction of the foot.
    The person skilled in the art can make numerous modifications and variations to the above-described ski boots to meet situation-specific and specific needs, which however are contained in the scope of protection defined by the following claims.
