Definitions

  • the present invention relates to a ski-boot.
  • the present invention relates to a ski-boot for alpine skiing or telemark, to which the following description refers purely by way of example, without this implying any loss of generality.
  • ski-boots for alpine skiing or telemark are generally made up of: a rigid shell made of plastic material, which is shaped in as to receive the skier's foot, and is provided at the bottom with a front sole and a rear heel made of anti-slip elastomeric material; a rigid bootleg made of plastic material, which is shaped so as to wrap round the ankle of the skier and is hinged to the top part of the shell so as to be able to rotate about a reference axis substantially coinciding with the articulation axis of the ankle; an internal shoe-liner made of soft and thermally insulating material, which is inserted in a removable manner inside the shell and the bootleg and is shaped so as to envelop and protect both the foot and the bottom part of the skier's leg; and a number of manually operated closing members, which are appropriately distributed on the shell and on the bootleg and are structured so as to be able to tighten both the shell and the bootleg so to immobilize the skier's leg
  • ski-boots for alpine skiing or telemark are moreover provided with a manually-operated collar locking device which can, according to the skier's choice and alternatively,
  • the top part of the shell of telemark ski-boots is also provided with a programmed deformation bellows, which extends astride of the metatarsal region of the foot so to allow the rear part of the shell to bend forwards with respect to the toe of the shell so as to favour the natural movement of the skier's foot.
  • ski-boots for alpine skiing or telemark in which the bootleg is integrally made of a composite material basically constituted by one or more superimposed layers of glass fibres and/or carbon fibres appropriately intertwined and/or superimposed on one another and embedded in a matrix of epoxy resin of a thermosetting type.
  • Said solution enables a slight reduction in the overall weight of the ski-boot, simultaneously increasing the structural stiffness of the ski-boot in the area of the ankle.
  • WO 99/10054 and EP 1221290 disclose similar ski boots, according to the preamble of claim 1.> Aim of the present invention is to further reduce the overall weight of ski-boots for alpine skiing or telemark, without however jeopardizing the flexibility of the shell. The latter being a characteristic that is essential for practising alpine skiing and telemark properly and in safe conditions.
  • a ski-boot is provided as specified in claim 1 and preferably, though not necessarily, in any one of the dependent claims.
  • the ski-boot 1 basically comprises an outer rigid shell 2, which is shaped so as to receive the skier's foot and is provided at the bottom with a front sole 3 and a rear heel 4 made preferably, though not necessarily, of anti-slip elastomeric material; and a rigid bootleg 5, which is shaped so as to wrap round the user's ankle and is hinged on the top part of shell 2 in order to be able to freely swing about a rotation axis A which is substantially perpendicular to the longitudinal mid plane of the ski-boot and which locally substantially coincides with the articulation axis of the user's ankle.
  • bootleg 5 is fixed in a freely swivelling manner on the shell 2 via two connecting hinges 6, which are positioned on the outer and inner lateral sides of shell 2, aligned along the axis A.
  • the ski-boot 1 is moreover provided with an internal shoe-liner 7 made of soft and thermally insulating material, which is positioned inside shell 2 and bootleg 5 preferably, though not necessarily, in a removable manner and is shaped so as to envelop and protect both the foot and the bottom part of the user's leg; and a number of manually operated closing members 8 which are appropriately distributed on shell 2 and on bootleg 5, and are structured so as to be able to selectively tighten shell 2 and/or bootleg 5 so as to immobilize the user's leg stably inside the ski-boot 1.
  • an internal shoe-liner 7 made of soft and thermally insulating material
  • the bootleg 5 consists of a shell 5 having preferably, though not necessarily, a monolithic structure and which is made of a composite material constituted by one or more superimposed layers of glass fibres and/or carbon fibres and/or aramidic fibres, appropriately intertwined and/or superimposed on one another and embedded in a matrix of epoxy resin, phenolic resin, or polyester resin of a thermosetting type.
  • shell 5 is also provided with a surface layer made of mono-oriented polyester-polyarylate fibres (commercially known as VECTRAN) embedded in the matrix of thermosetting resin.
  • Said surface layer forms the entire internal surface 5a of shell 5, i.e. the surface of shell 5 facing shell 2 and the shoe-liner 7, and performs the dual function of absorbing the mechanical vibrations in the contact areas between bootleg 5 and the shell 2 and of preventing any splinters of composite material deriving from possible breaking of the shell 5 from reaching the user's leg.
  • shell 2 is, instead, formed by a front half-shell 9 and a rear half-shell 10, fixed in a rigid and unmovable way to one another.
  • the front half-shell 9 has a substantially ogival shape, covers completely the user's toes approximately up to the beginning of the plantar arch area and is entirely made of at least one non-reinforced plastic polymer, via a process of injection moulding of a known type.
  • front half-shell 9 is entirely made of at least one homogeneous plastic polymer that does not enclose reinforcement fibres, such as, for example, high-density polyurethane and/or polyester and/or polyether amide (commercially known as PEBAX) and/or other similar plastic polymers, through a process of injection moulding.
  • reinforcement fibres such as, for example, high-density polyurethane and/or polyester and/or polyether amide (commercially known as PEBAX) and/or other similar plastic polymers
  • the rear half-shell 10 completely covers the remaining part of the user's foot, starting substantially from the boundary between the plantar arch and the metatarsal region of the foot, and is entirely made of a composite material constituted by one or more superimposed layers of glass fibres and/or carbon fibres and/or aramidic fibres, appropriately intertwined and/or superimposed on one another and embedded in a matrix of epoxy resin, phenolic resin, or polyester resin of a thermosetting type.
  • the front half-shell 9 of shell 2 is moreover provided with a transverse elastically deformable portion 9a which extends from one side to the other of the shell 2, approximately astride of the metatarsal region of the foot, and is structured so as to enable the front half-shell 9 to deform locally in an elastic way in order to enable the entire shell 2 to bend in the metatarsal region of the foot and favour possible bending of the user's foot.
  • sole 3 is stably fixed on the bottom wall of front half-shell 9, and front half-shell 9 is divided into a front portion and a rear portion, both of which are substantially rigid and undeformable, and into an elastically deformable intermediate portion 9a that extends on the top wall of the front half-shell 9 from one side to the other of the shell 2, roughly above the metatarsal region of the foot and almost reaching sole 3 so to separate and joint together the front portion and the rear portion of front half-shell 9.
  • the elastically deformable portion 9a of front half-shell 9 is formed by a programmed deformation bellows 9a extending from one side to the other of the shell 2, roughly astride of the metatarsal region of the foot, and almost reaching sole 3, and which is structured so as to allow the user's toes to freely bend by a few degrees.
  • bellows 9a i.e. the elastically deformable portion 9a of front half-shell 9 extends from one side to the other of shell 2 following a slightly oblique arched path, so that the end on the inner side of shell 2 is located further forwards with respect to the end set on the outer side of shell 2 so as to follow the natural bending axis of the foot.
  • front half-shell 9 is preferably, though not necessarily, also provided with a projecting appendage 9b of a substantially duck-bill shape, which prolongs in cantilever manner from the toe of the ski-boot 1 remaining substantially coplanar to the sole 3 and is structured in so to be able to couple in a rigid and stable, but easily releasable manner with the forward piece of any known-type ski-coupling device.
  • rear half-shell 10 instead, substantially has the shape of a tub without one of the smaller side walls, and is telescopically inserted inside the front half-shell 9 so to form a single body with the latter.
  • the rear half-shell 10 is moreover provided with a plane projecting tongue or flap 10a, which prolongs in cantilever manner inside the front half-shell 9 remaining locally tangential to the bottom wall of the front half-shell 9, on the opposite side of sole 3, more or less as far as the bottom of the front half-shell 9, and adheres stably to the bottom wall of the front half-shell 9 throughout the contact area with the front half-shell 9.
  • the rear half-shell 10 is moreover provided with a surface layer made of mono-oriented polyester-polyarylate fibres (commercially known as VECTRAN) embedded in the matrix of thermosetting resin.
  • Said surface layer forms the entire internal surface 10b of the rear half-shell 10, i.e. the surface of the rear half-shell 10 directly facing the shoe-liner 7, and performs the dual function of absorbing the mechanical vibrations in the contact areas between shell 2 and shoe-liner 7 and of preventing any splinters of composite material deriving from possible breaking of the rear half-shell 10 from reaching the user's foot.
  • shell 2 is preferably, though not necessarily, also provided with an insole 11 made of foamed plastic polymer, which has the function of absorbing the mechanical vibrations in the contact areas between shell 2 and shoe-liner 7, and is fixed in an unmovable manner on the bottom of the shell 2, astride of the front half-shell 9 and the rear half-shell 10 so as to coat substantially the entire internal surface of shell 2 which is to support the sole of the user's foot.
  • insole 11 made of foamed plastic polymer
  • insole 11 has preferably, though not necessarily, the shape of a tray, and is made of ethylene-vinyl-acetate foam with closed cells (commercially known as EVA).
  • heel 4 of shell 2 is an element which is completely separate from the rear half-shell 10, and which is attached to the rear half-shell 10 by means of a metal supporting bracket 12 which, in turn, is rigidly fixed on the outside of the rear half-shell 10, on the area corresponding to the heel of the foot, and is preferably, though not necessarily, structured so as to be able to couple in a rigid and stable, but easily releasable, manner with the heel piece of any known type ski-coupling device.
  • the metal supporting bracket 12 is substantially L-shaped so that a first portion 12a of the bracket extends underneath the rear half-shell 10, towards the toe of the ski-boot, remaining locally adherent to the outer surface of the rear half-shell 10, whilst the second portion 12b of the bracket prolongs upwards, remaining always locally adherent to the outer surface of the rear half-shell 10, up to almost reach the attachment of Achilles tendon after passing completely over the heel of the foot.
  • Heel 4 instead, consists of a wedge of anti-slip elastomeric material, which is fixed directly on the horizontal portion 12a of the bracket, on the opposite side of the rear half-shell 10.
  • ski-boot 1 is preferably, though not necessarily, also provided with a manually-operated bootleg locking device 13 which, according to the skier's choice and alternatively, is able to rigidly clamp the bootleg 5 to the shell 2 so to prevent any relative movement between the two elements; engage the bootleg 5 to the shell 2 so as to allow only positive oscillations of the bootleg 5 about the axis A, which, starting from a pre-set resting position, bring bootleg 5 up toward the toe of shell 2 of ski-boot 1; or else release bootleg 5 from shell 2 so as to allow the bootleg 5 to freely oscillate about the axis A both forwards and backwards.
  • a manually-operated bootleg locking device 13 which, according to the skier's choice and alternatively, is able to rigidly clamp the bootleg 5 to the shell 2 so to prevent any relative movement between the two elements; engage the bootleg 5 to the shell 2 so as to allow only positive oscillations of the bootleg 5 about the axis A, which, starting from a pre-set

  • the distal end of coupling lever 16 In the first operating position, the distal end of coupling lever 16 is engaged to the anchorage plate 15 so as to rigidly clamp the bootleg 5 to the rear half-shell 10 and prevent any relative movement between the two elements.
  • the distal end of coupling lever 16 In the second operating position, the distal end of coupling lever 16 is set bearing upon the surface of the rear half-shell 10, immediately above the anchorage plate 15, and can bear upon the anchorage plate 15 so as to allow only oscillations of the bootleg 5 about axis A which, starting from a pre-set resting position, bring the bootleg 5 up toward the toe of the ski-boot 1, i.e. to the front half-shell 9.
  • coupling lever 16 is set bearing upon the surface of the rear half-shell 10, immediately underneath the anchorage plate 15 so as to release the bootleg 5 from the rear half-shell 10 and allow the bootleg 5 to freely oscillate about axis A both forwards and backwards.
  • the anchorage plate 15 is preferably, though not necessarily, made in one piece with the metal supporting bracket 12 that connects the heel 4 to the rear half-shell 10, and is provided with a cylindrical transverse pin 15a which is fixed to the body of the metal supporting bracket 12 at a given distance from the surface of the rear half-shell 10 and so to be parallel to the rotation axis B of the lever; whilst the distal end of coupling lever 16 is provided with a transverse groove or indent (not visible in the figures), which extends on the lever body parallel to axis B and is sized so as to receive and trap temporarily the transverse pin 15a.
  • the bootleg locking device 13 is preferably, though not necessarily, also provided with a closing lace 18 which has its two ends fixed to two opposite side flaps of the bootleg 5 so as to completely surround the bootleg 5, and is centrally engaged to the coupling lever 16; and a pair of driving elements 19 which are fixed on the outer surface of the bootleg 5 on opposite sides of the top supporting plate 14 and are slidably engaged by the two stretches of the closing lace 18.
  • the driving elements 19 are designed to keep the two terminal portions of closing lace 18 which cross over each other on the front part of bootleg 5, in a position astride of the two opposite side flaps of bootleg 5, so that the positioning of coupling lever 16 in any of the three operating positions described above will enable tensioning of the closing lace 18, which, in turn, pulls the two opposite side flaps of bootleg 5 one against the other so to tighten the bootleg 5 against the shoe-liner 7 and block the user's ankle stably inside the ski-boot 1.

  • the ski-boot 1 is provided with only one other manually operated closing member 8, which is designed to tighten the shell 2 so to immobilize the user's foot stably inside the ski-boot 1.
  • Said closing member 8 is preferably, though not necessarily, constituted by a traditional clamping hook 8 with manually operated tensioning leverage, which is positioned crosswise on the outer surface of the rear half-shell 10, astride of the longitudinal opening (not illustrated) that allows the user to inserted his foot inside the shell 2.
  • the clamping hook 8 is a component already widely known in the field and hence won't be further described.
  • ski-boot 1 Operation of ski-boot 1 is practically identical to that of any other ski-boot for alpine skiing or telemark currently on the market and hence does not require any further explanations.
  • construction of the front portion of shell 2 in normal plastic polymer prevents the mechanical stresses that are transmitted from the ski-boot 1 to the forward piece of the ski-coupling device from causing an unexpected and sudden crumbling of the parts made of composite material.
  • anchorage plate 15 is made in one piece with the metal supporting bracket 12 which connects the heel 4 to the rear half-shell 10 and is moreover structured so to be able to couple in a rigid and stable, but easily releasable, manner with the heel piece of the ski-coupling device, enables all mechanical stresses transmitted by bootleg 5 to be discharged directly on the heel piece of the ski-coupling device, without involving the rear half-shell 10.
  • the rear half-shell 10 is not subjected to repetitive bending loads that could cause failure due to fatigue of the composite material, making possible a drastic reduction in the thickness of the wall of composite material to the advantage of lightness and of reduction in the production costs of the rear half-shell 10.
