Description
- The present invention generally regards the technical field of winter sports footwear, and it particularly regards a ski boot.
- Use of ski boots is generally known. Such ski boots are generally "standard" and they are formed by a cuff, a lower shell coupled to the cuff and a liner arranged inside the first two to receive the foot of the user.
- Thus, ski boots have a discontinuity arranged in central position on the lower shell and on the cuff to define a pair of end portions mutually slidable to tighten/widen the ski boot.
- To this end, a pair of hooks and a pair of seats arranged at the cuff and a pair of hooks and a pair of seats arranged at the lower shell, are generally present.
- Whenever there arises the need to vary the configuration of the ski boot, for example whenever required to tighten/widen it prior to/after descending, there arises the need for the user to clean the ski boot of the snow and act on each single hook to open/close it.
- Furthermore, such operation is required each time the user decides to insert/remove the foot into/from the ski boot, for example after skiing.
- Furthermore, when intending to take a break the user is forced to open all hooks so as to remove the foot from the ski boot, with the disadvantages outlined above, or is forced to release the ski boot from the ski and walk with the ski boot which, besides ruining the latter, also makes the walking difficult and uncomfortable.
- In any case, whenever the user releases the hooks for example for the insertion/removal of the foot or for widening the ski boot ready for descent, it loses the initial configuration of the ski boot. In other words, each time the user is forced to act on each single hook and remember which was the correct configuration.
- Such operations are in any case particularly long and difficult, especially in the conditions in which the user is generally found during the use of the ski boot.
- Such disadvantages are even more marked should the user be a particularly skilled or professional skier, or the descents to be executed be particularly difficult, given that the user is forced to tighten and widen the ski boot at the start and at the end of each descent.
- Solutions have been provided in the art, see in particular
US 2014/373393 A1 ,CH 688 606 A5 WO 90/05466 A1 - An object of the present invention is to at least partly overcome the aforementioned drawbacks, by providing a ski boot that is highly functional, easy to manufacture and inexpensive.

- Another object of the invention is to provide a ski boot in which it is particularly easy and quick to vary the configuration thereof.
- Another object of the invention is to provide a ski boot that maintains the initial adjustments during and after use.
- Another object of the invention is to provide a ski boot that allows the removal of the liner.
- Another object of the invention is to provide a ski boot that is particularly comfortable to use.
- These and other objects that will be more apparent hereinafter, are attained by a ski boot according to what is described, illustrated and/or claimed herein.

lower shell 30 may be arranged above thecuff 10 and it may be generally cylindrical-shaped to surround the lower part of the leg of a user thus defining an axis X. - On the other hand, the sole of the
cuff 10 designed to rest against the skis or the ground may define a plane π substantially perpendicular to the axis X. - The
cuff 10 and thelower shell 30 may be coupled so that the axis X is slightly inclined with respect to the plane π. Such inclination may affect the posture of the user when skiing and it may be fixed or adjustable on the ski boot by means of systems of the known type. Furthermore, even the material with which thelower shell 30 is made determines the flexibility thereof and thus the flexibility of the ski boot 1 during use. - The
cuff 10 and thelower shell 30 may thus be coupled to define a substantiallyrigid support structure 2 suitable to contain inside theliner 90. The latter may be configured to receive the foot of the user. - The
liner 90 may be of per se known type. For example, it may be made so as to thermally insulate the foot of the user, so as to form a soft layer to be interposed between the foot of the user and thesupport structure 2 and so as tom position the foot in thesupport structure 2 in an optimal manner, for example with the correct inclination with respect to the ground. - As known, during use, the ski boot 1 must be particularly adherent to the foot of the user.
- To this end, the
support structure 2 may comprise adiscontinuity 3 to define twoopposite end portions lower shell 30 and thecuff 10 may comprisesuch discontinuity 3 so that both have the pair of opposite ends mutually slidable. - Preferably, as schematically illustrated in
figures 8 to 10 , the twoend portions support structure 2, so as to vary the configuration of the ski boot 1 i.e. Move from a narrow to a wide configuration and vice versa. - The
end portions - For example, the initial position of the
ends - Such operative positions may vary depending on the needs of the user, for example depending on the characteristics of the foot.

end portions - Preferably, even the initial position of the
end portions - In other words, as better outlined hereinafter, the distance of the
end portions - Suitably,
devices 50 for connecting theend portions lower shell 30 and thecuff 10 at thediscontinuity 3 may be provided for. - For example, two
connection devices 50 arranged on thelower shell 30 and twoconnection devices 50 arranged on thecuff 10 may be provided for. It is clear that such example is not exclusive and theconnection devices 50 may vary in number or be arranged at different position. - The
connection devices 50 may thus allow to keep theend portions - Each
connection device 50 may comprise a pair of male 51 and female 52 elements which may be operatively connected with theend portions support structure 2. - For example, the
end 5 may comprise at least oneseat 52 while themale element 51, for example a hook, may be operatively connected with theend 4. - More in particular, the
seat 52 may comprise a plurality ofgrooves 53 so that thehook 51 can be inserted into any of the latter so that theend portions - In other words, the
connection devices 50 may be substantially adjustable to vary the predetermined mutual distance corresponding to the initial position of theend portions - Thanks to such characteristic, each
hook 51 may thus be positioned in one of thegrooves 53 of the corresponding seat 52so as to define the initial position. It is clear that thedifferent connection devices 50 may thus be adjusted differently on the same ski boot 1. - The user may thus determine the mutual distance of the
end portions connection device 50. - In this manner, the ski boot 1 may adapt to the different needs of the user.
- Furthermore, upon determining the initial position of the
end portions connection device 50 to promote the sliding of theend portions - On the other hand, according to a preferred but non-exclusive embodiment of the invention, the ski boot 1 may comprise at least one
lever 60 to promote the sliding of theend portions 4, 5between the initial and operative positions so as to vary the configuration of the ski boot 1. - Suitably, the
lever 60 may be configured to act simultaneously on allconnection elements 50. - For example, at least one
tensioner 61 for connecting thehook 51 with theend 5 of thesupport structure 2 may be provided for. Preferably, a plurality oftensioners 61, one for eachhook 51 may be provided for. - Suitably, guide means 40 for
tensioners 61 may be provided for so as to guide the sliding of the latter upon the sliding of theend portions grooves 41 and/or a plurality of idlers orpulleys 42 arranged on thesupport structure 2. - Though not shown in the attached figures, it is clear that one or more protection elements may be provided for so as to keep the
guides 41, theidlers 42 and thetensioners 61 protected and not accessible to the user. For example, a protection guard may be provided for or theguides 41 andidlers 42 may rest inside thecuff 10. - The lever 60may thus be operatively connected with all
tensioners 61 so that the actuation of the former promotes the sliding of the latter so that theend portions - In other words, the
lever 60 may thus simultaneously act on alltensioners 61 and thus on allconnection devices 50. In particular, thelever 60 may act on alltensioners 61 with the same force. - For example, a
ring 45 connected with thelever 60 may be provided for. Thetensioners 61 may be connected withsuch ring 45 so that the displacement of the latter promotes the simultaneous displacement of all tensioners 61. - It is clear that such solution is not exclusive.

lever 60 may be hinged so that the rotation thereof around a hinging point promotes the extension of thetensioners 61. - Suitably, the foot inside the ski boot 1 may be compressed maintaining the different proportions between the
different connection devices 50, i.e. the difference between the different predetermined distances of theend portions - For example, the user may configure the
connection devices 50 on thelower shell 30 so that theend portions connection devices 50 on thecuff 10 so that theend portions - Such differences will remain substantially intact even once the
end portions - Thus, the user may advantageously actuate the
lever 60 only to move from the initial position to the operative position and vice versa. - In this manner, such operation may be particularly quick and simple to obtain, even in the typical conditions of use like in the presence of cold and snow. For example, the
lever 60 may be configured so as to be simple to actuate even when wearing ski gloves. - Furthermore, the
end portions hook 51 from theseat 52 so as to maintain the adjustment of the initial position chosen by the user. - In other words, upon positioning the
hooks 52 in thesuitable groove 53, one may pass from the wide configuration and the narrow configuration of the ski boot 1 by acting using onelever 60 only. - Safety means 70 may be suitably provided for to prevent the inadvertent removal of the male and
female elements - According to a different embodiment, the
male elements 51 of theconnection devices 50 may comprise a pair of screw-lead-screw elements 57 that can be mutually screwed so as to predetermine the initial position. - More in detail, the
male element 51 may comprise anend 54 that can be inserted into theseat 52, anopposite end 55 coupled with thetensioner 61 while the screw-lead-screw elements 57 may rest interposed between theends - In particular, the
female element 52 may comprise an abutment element 52' for theend 54 of the male element so that the latter abuts against abutment element 52'. - The screw-lead-
screw elements 57 may thus vary the distance between theend 55 and the abutment element 52' so as to define the plurality of initial positions of theend portions - Thanks to such characteristic, as schematically illustrated in
Figs. 11, 12 and 13 the distance between theends end portions - In this manner, similarly to the description outlined above regarding the
hooks 51, a predetermined initial position may be firstly determined and then move from the initial position to the operative positions of theend portions lever 60. - In other words, the mutual distance of the
end portions - As schematically illustrated in
Figs. 5, 6 and 7 , thelever 60 may be a longitudinal element, as illustrated inFIGS.. 2, 3 and 4 may be a ratchet - In the first case there may be a simple and quick adjustment, i.e. by actuating the
lever 60 the same may thus move from an inoperative position corresponding to the initial position of theend portions 4, 5 (Figs. 2 ,5 and8 ) to an operative position corresponding to the operative position of theend portions 4, 5 (Fig. 3 ,6 and9 ). A plurality of operative positions may possibly be provided for. For example, thelever 60 may be further rotated to a further operative position (Figs. 4 ,7 and10 ). - It is clear that further operative positions not illustrated in the attached figures may be provided for.
- On the other hand, in the second case, thanks to the characteristics of the
ratchet 60 which may be of the per se known type, theend portions - In any case, safety means may be provided for so as to prevent the inadvertent displacement of the
lever 60. For example, elements such as hooks may be provided for so as to hold thelever 60 in the operative positions. - In order to allow the insertion of the foot of the user into the ski boot 1 the male 51 and female 52 element may have to be de-coupled, i.e. open the
connection devices 50 or it may be sufficient to bring theend portions - On the other hand, according to a particular embodiment, a
rear area 20 that can be opened so as to allow the insertion and/or the removal of theliner 90 into/from thesupport structure 2 may be provided for. - In this case, the mutual distance of the
end portions rear area 20. - Advantageously, the foot of the user may be inserted and removed into/from the
support structure 2 together with theliner 90. - Suitably, the latter may be configured to allow the user to walk.
- The
liner 90 may thus have a substantially rigid sole 91 so as to allow the user to walk and it may have closing means 92 for closing it such as a footwear of the known type. For example, one ormore laces 92 may be provided for. - In this manner, the user may move away from the skis while the
support structure 2 may stay attached to the skis and maintain the configuration with the adjustments of theconnection devices 50 which may thus remain intact. - In particular, the
rear area 20 may be rotationally coupled with thecuff 10 in proximity of therear area 20 and above it so as not to hinder the attachments for the skis which are of the standard type. - Thus, the
rear area 20 may rotate between an open position (Fig. 17 ) and a closed position (Fig. 19 ) in which it is integrally joined with thesupport structure 2. - Suitably, a plurality of
means 80 for the selective locking of therear area 20 with thesupport structure 2 may be provided for. Such locking means 80 may be of the per se known type, preferably of the quick release type. - According to a particular aspect of the invention, the locking means 80 may comprise at least one
pair push buttons 81, levers or the like to be actuated simultaneously by the user so as to release such locking means 80. This may allow to prevent the inadvertent release of the locking means 80. - The locking means 80 may be of the per se known type, for example they may be one or more pairs of snap-coupled male and female elements.
- According to an aspect of the invention, a
gasket 85 may be interposed between thesupport structure 2 and therear area 20, in particular between the mutual edges so that the ski boot 1 is sealed against water and snow upon closing therear area 20. - It is clear that in this case the
liner 90 must not necessarily be sealed against water and snow. - Operatively, the locking means 80 may be released, the
rear area 20 may be rotated up to the open position and theliner 90 may be inserted, as schematically illustrated inFigs. 17 to 19 . - On the other hand, irrespective of this, one may act on the
connection devices 50 so as to define the initial position of theend portions - Thus, one may act on the
lever 60 so as to approach theend portions - Possibly, one may further act on the
lever 60 to promote the further approaching of theend portions - Even though the invention has been described with reference to the attached figures, the reference numbers utilised in the description and in the claims are meant for improving the intelligibility of the invention and thus do not limit the claimed scope of protection in any manner whatsoever.
