Definitions

  • the present invention relates to a ski boot.
  • the present invention relates to an alpine or Telemark ski boot, use to which the following description refers purely by way of example without this implying any loss of generality.
  • more recent alpine or Telemark ski boots normally consist of a rigid shell made of plastic material which is shaped so as to receive the foot of the skier, and is bottomly provided with a front sole and with a rear heel usually made of a non-slip elastomeric material; of a rigid cuff made of plastic material which is C-shaped so as to surround the ankle of the skier from behind, and is hinged to the upper part of the shell so as to be able to rotate about a transversal reference axis substantially coincident with the articulation axis of the ankle; and of an inner liner made of soft, thermal-insulating material, which is removably inserted inside the shell and the cuff, and is shaped so as to surround and protect both the foot and the bottom part of the leg of the skier; and of a protective upper tongue made of plastic material, which has the bottom end hinged to the shell, immediately above the tarsal-phalangeal area of the foot, and extends along the upper part of the shell up to just
  • Alpine or Telemark ski boots are also provided with a number of manually-operated closing buckles which are conveniently distributed on the shell and on the cuff, and are structured so as to be able to selectively close/tighten the shell and the cuff so as to stably immobilize the leg of the skier within the boot; and of a manually-operated cuff locking device, which straddles the shell and the cuff, in the area immediately above the heel, and is structured so as to be able to adjust the pivoting ability of the cuff with respect to the shell.
  • the cuff locking device is structured so as to be able, on choice, to rigidly fix the cuff to the shell so as to prevent any relative movement between the two components; or to completely release the cuff from the shell so as to allow the cuff to freely pivot about the articulation axis of the ankle both forward and backward.
  • the rigidity of the protective tongue may be a hindrance to the movement of the cuff
  • almost all alpine and Telemark ski boots have, at the bend or elbow of the tongue, a transversal gusseted folding which extends from one lateral side to the other of the tongue, and is structured so as to allow, when needed, the protective tongue to elastically bend so as to go along with the pivoting of the cuff with respect to the shell, hence making the boot more flexible and comfortable during walking.
  • the tibia of the user may still tilt forward by some degrees without any hindrance due to the elastic bending of the upper part of the protective tongue, and to the two side strips of the cuff which saddle each other above the upper part of the protective tongue.
  • alpine and Telemark ski boots have decided to provide their alpine and Telemark ski boots with a soft tongue and with a rigid tongue, which are easy to interchange with each other.
  • the transversal folding with programmed deformation is only on the soft tongue while the rigid tongue is generally provided with longitudinal stiffening ribs.
  • Aim of the present invention is to provide an alpine or Telemark ski boot which is simpler and more practical to use, and which is also capable of blocking the movement of the ankle of the user more efficiently, without however prejudicing the comfort of the fit.
  • a ski boot as defined in claim 1 and preferably, though not necessarily, in any one of the dependent claims.
  • number 1 indicates as a whole a ski boot, and in particular a ski boot specifically structured for alpine or Telemark skiing.
  • Boot 1 basically consists of a rigid outer shell 2 made of plastic or composite material, which is shaped so as to receive the foot of the user, and is bottomly provided with a front sole 3 and a rear heel 4 preferably, though not necessarily, made of a non-slip elastomeric material; and of a rigid cuff 5 made of plastic or composite material, which is shaped so as to surround the bottom part of the leg of the user, and is hinged on the upper part of shell 2 so as to be able to freely tilt about a transversal reference axis A, which is substantially perpendicular to the centreline plane of the boot (i.e. perpendicular to the plane of the sheet of paper in Figure 1 ), and is also locally substantially coincident with the articulation axis of the ankle of the user.
  • a transversal reference axis A which is substantially perpendicular to the centreline plane of the boot (i.e. perpendicular to the plane of the sheet of paper in Figure 1 ), and is also locally substantially coinciden
  • cuff 5 is freely pivotally fixed on shell 2 by means of two connecting hinges 6, which are positioned on the outer and inner lateral sides of shell 2 and of cuff 5, aligned along axis A so as to allow cuff 5 to tilt/rotate on shell 2 while always staying locally substantially coplanar to a reference plane orthogonal to axis A.
  • boot 1 is also provided with an inner liner 7 which is preferably made of soft and thermal insulating material, is preferably, though not necessarily, removably accommodated within shell 2 and cuff 5 and lastly, is shaped so as to surround and protect both the foot and the bottom part of the leg of the user; and of an oblong and convex protective tongue 8 which is preferably, though not necessarily, made of plastic or composite material, and is arranged resting on shell 2 in the area above the instep of the foot and the front part of the leg, to cover a longitudinal slit 2a which extends along the upper ridge of shell 2, i.e.
  • the longitudinal slit 2a allows the upper part of shell 2 to elastically widen so as to allow the user to slip his/her foot into liner 7 more easily.
  • the protective tongue 8 essentially consists of an oblong and convex rigid shell 8, which is substantially L-bent so as to copy the profile of the upper part of shell 2.
  • the bottom portion 8a of protective tongue 8 extends above shell 2, to completely cover the initial stretch of the longitudinal slit 2a which extends above the instep of the foot, approximately starting from the metatarsal area of the foot; while the upper portion 8b of the protective tongue 8 extends above shell 2 and underneath cuff 5, to completely cover the final stretch of the longitudinal slit 2a which is arranged substantially in front of the ankle and of the bottom part of the tibia of the user.
  • the bottom portion 8a and the upper portion 8b of protective tongue 8 are also structured so to be substantially rigid and indeformable, and the protective tongue 8 is also provided with an intermediate, elastically-deformable portion 8c which is more or less positioned at the bend of the tongue, so as to join the bottom portion 8a and the upper portion 8b of the tongue to each other, and is structured so as to allow the protective tongue 8 to elastically bend at the middle elbow thereof.
  • the intermediate elastically-deformable portion 8c of the tongue is preferably, though not necessarily, positioned immediately below the point in which the tongue 8 slips underneath the cuff 5, i.e. more or less at the height where the tibia joins the talus bone of the foot.
  • the intermediate portion 8c of the tongue preferably, though not necessarily, consists of gusseted folding 8c with programmed deforming, which extends from one side to the other of the protective tongue 8, more or less at the bend or elbow of the tongue (i.e. at the height where the tibia joins the talus bone of the foot), and is structured so as to allow the upper portion 8b of the tongue to freely tilt forward towards the bottom portion 8a of the tongue which rests on the area of shell 2 above the instep of the foot, thus going along with any tilting of cuff 5 with respect to shell 2.
  • the bottom portion 8a of protective tongue 8 is preferably, though not necessarily, hinged directly on shell 2 behind the tip of the latter (i.e. approximately above the tarso-phalangeal joint area of the foot), so that the entire protective tongue 8 may freely rotate about a reference axis locally substantially perpendicular to the longitudinal centreline plane of the boot, i.e. locally substantially parallel to tilting axis A of cuff 5, so as to tilt forward and leave free access to the longitudinal slit 2a of the shell.
  • boot 1 also comprises a manually-operated cuff locking device which straddles shell 2 and cuff 5, in the rear area of boot 1 arranged immediately above the heel, and is structured so as to be able, on choice, to:
  • the cuff locking device 9 preferably, though not necessarily, comprises: a rigid connection rod or strut 10, which has the lower end 10a hinged to shell 2 more or less at the heel of the boot, so as to be able to freely rotate about a reference axis B which is locally perpendicular to the centreline plane of the boot (i.e. perpendicular to the plane of the sheet of paper in Figure 1 ), and which extends substantially on the centreline plane of the boot, i.e.
  • a mechanical strut-locking member 11 which is rigidly fixed on cuff 5, immediately above the heel of the boot, so as to be engaged in axially sliding manner by the upper part 10b of strut 10, and is structured so as to be able to selectively prevent any relative movement between the strut 10 and the mechanical strut-locking member 11 so as to rigidly connect the cuff 5 to shell 2.
  • the mechanical strut-locking member 11 is a component already widely known and used in the field of alpine ski boots, and hence will not be further described.
  • the cuff 5 consists of a rigid front greave 12 and a rigid rear greave 13, which are adapted to mutually couple to one another so as to form a rigid and detachable tubular body 5, which is provided with a substantially tubular-cylindrical shaped upper annular band or ring 5a which completely surrounds the leg of the user, and with two flat lateral appendages 5b which extend downwards, on opposite sides of the centreline plane of the boot, so as to reach the two connecting hinges 6 arranged on the lateral sides of shell 2.
  • the rigid rear greave 13 covers the rear part of the leg of the user, is mechanically constrained to shell 2 by means of the cuff locking device 9, and is hinged directly on the outer and inner lateral sides of shell 2 by means of the two connecting hinges 6, so as to be able to freely rotate about axis A thus remaining on the centreline plane of the boot.
  • the cuff locking device 9 straddles between shell 2 and the rigid rear greave 13, in the area of boot 1 arranged above the heel.
  • the rigid front greave 12 covers the upper part 8b of the protective tongue 8, which in turn covers the front part of the leg of the user, and is hinged on the lateral sides of the rigid rear greave 13 more or less at the two connecting hinges 6, so as to be able to freely rotate about axis A together with, or separately from, the rigid rear greave 13, thus remaining on the centreline plane of the boot.
  • the rigid front greave 12 and the rigid rear greave 13 are hinged to each other more or less at the flat lateral appendages 5b of the rigid tubular and detachable body 5, so as to open as a compass with respect to each other.
  • the rigid front greave 12 may, on choice, rotate about axis A in single block with the rigid rear greave 13, and with the limits set by the cuff locking device 9; or tilt/rotate forward in an independent manner from the rigid rear greave 13, so as to open/decompose the two halves of the upper annual ring 5a.
  • cuff 5 is also provided with a manually-operated greaves closing device 14, which is structured so as to be able to selectively maintain the rigid front greave 12 stably and rigidly coupled to the rigid rear greave 13, so as to form/ compose the rigid and detachable tubular body 13.
  • the rigid front greave 12 is lastly shaped so as to be able to mechanically couple with the upper part 8b of the protective tongue 8, so as to prevent the protective tongue 8 from freely moving underneath the rigid front greave 12, when the rigid front greave 12 is rigidly coupled with the rigid rear greave 10 to form/compose the rigid and detachable tubular body 5.
  • the rigid rear greave 13 consists of a more or less semi-cylindrical rigid shell 13 made of plastic or composite material, which is shaped so as to cover the rear part of the leg of liner 7, more or less in the area from the calf down to where it joins the Achilles tendon, and is hinged directly on the outer and inner lateral sides of shell 2 by means of the two cuff-articulation hinges 6, so as to be able to freely rotate about axis A while remaining on the centreline plane of the boot.
  • the rigid front greave 12 consists of a more or less semi-cylindrical rigid shell 12 made of plastic or composite material, which is shaped so as to cover the upper part 8b of protective tongue 8, and is hinged to the lateral sides of the rigid rear greave 13 at the two cuff-articulation hinges 6, so as to be able to freely rotate about axis A together with or separately from the rigid rear greave 10, thus remaining on the centreline plane of the boot.
  • the rigid shell 12 forming the rigid front greave 12 is preferably, though not necessarily, also provided with at least one tooth, ridge, a transversal rib or other coupling protuberance 15 which overhangingly protrudes from the inner concave surface 12a of the shell, and is dimensioned so as to be able to engage/mesh in a corresponding coupling seat or groove 15a realized on the upper portion 8b of the tongue, so as to prevent any movement of the upper portion 8b of the tongue with respect to the rigid front greave 12.
  • the protective tongue 8 is equipped with a number (three in the example shown) of coupling seats or grooves 15a conveniently staggered vertically along the upper portion 8b of the tongue, while the rigid shell 12 is provided with a number (two in the example shown) of transversal coupling ribs 15 which overhangingly protrude from the inner concave surface 12a of rigid shell 12, one above the other, and each of which is dimensioned so as to be able to engage/mesh in any one of the coupling seats or grooves 15a vertically staged along the upper portion 8b of the tongue.
  • coupling protuberance(s) 15 may also be realized on the upper portion 8b of the protective tongue 8, and that the coupling seat(s) or the groove(s) 15a may be realized on the inner concave surface 12a of the rigid shell 12.
  • the greaves closing device 14 instead preferably, though not necessarily, consists of a manually-operated winch fastening device 14, as the one marketed by American company BOA TECHNOLOGY INC, which has the winch-holder unit 14a rigidly fixed on the outer surface of the rigid front 12 or rear greave 13, and has the two tensioning cables 14b which extend from the winch-holder unit 14a so as to tighten and/or couple with the other rigid greave 12, 13, on opposite sides of the centreline plane of the boot.

  • Winch fastening device 14 is a component already known in the field of footwear, and was already shown and described in patent applications US19970917056 , WO1998 US16314 , JP20000507254 , US20010956601 , US20010099566 , US19990337763 , JP20010519784 , W02000 US19440 , US19990388756 , US20010993296 , US20030459843 , US20050263253 , US20070841872 , US20070842009 , US20070841997 , US20070842013 , US20070842005 , W02005 US39273 and US20040623341P , to which reference is directly made for all further details on the structure and/or operation of the device.
  • boot 1 is provided with a number of manually-operated mechanical boot-closing devices 16, which are suitably distributed to straddle shell 2 and the protective tongue 8, and are structured so as to be able to selectively rigidly fix the protective tongue 8 on shell 2, and at the same time tighten the shell 2 to stably immobilize the leg of the user inside boot 1.
  • the mechanical closing devices 16 preferably, though not necessarily, consist of a series of lever-operated closing buckles 16 which are arranged above the instep of the foot, straddling the shell 2 and the protective tongue 8, so as to be able to tighten the shell 2 while, at the same time, immobilizing the bottom portion 8a of protective tongue 8 in abutment against the upper part of shell 2.
  • the lever-operated closing buckles 16 are components already widely known in the field of ski boots, and hence will not be further described.
  • sky boot 1 General operation of sky boot 1 is easy to infer from the above disclosure, and hence does not require further explanations. Rather than to specify that, in addition to controlling the movement of cuff 5 by means of the cuff locking device 9, the user now also has the opportunity of releasing/decoupling the rigid front greave 12 from the rigid rear greave 13, and then of walking while leaving the rigid front greave 12 free to move forward thus going along with the movement of the leg of the user. Thereby, the sky boot 1 resistance to bending is exclusively determined by the protective tongue 8, which remains rigidly fixed to the shell 2 by means of the mechanical closing devices 16.
  • the front part of cuff 5 now corresponds to the middle part of the rigid front greave 12, and hence has a much superior structural rigidity than the one provided by the current C-shaped cuffs made of plastic material.
  • the upper annular band or ring 5a of cuff 5 is sufficiently rigid to prevent even the smallest forward bending of the tibia.
  • cuff 5 makes the insertion of the foot into boot 1 much simpler and faster.
  • the rigid front greave 12 may be hinged to the rigid rear greave 13 by means of two auxiliary connecting hinges 6', which are arranged on the outer and inner lateral sides of the rigid rear greave 13, vertically staggered immediately above the two connecting hinges 6, and are aligned along a reference axis C locally parallel to and separated from axis A.
  • the rigid front greave 12 may rotate on the body of the rigid rear greave 13 about axis C to open and close as a compass, and may also rotate together with the rigid rear greave 13 about axis A to copy the movement of the bottom part of the leg.
  • the protective tongue 8 may consist of a piece of synthetic fabric of suitable thickness, possibly coupled with an impermeable film, which is fixed on the upper part of shell 2 preferably, though not necessarily, by means of gluing, to cover the longitudinal opening 2s.
  • the cuff locking device 9 may be structured so as to be able to, on choice:
