Definitions

  • the present invention relates to a ski boot.
  • the present invention relates to a ski touring or telemark boot, to which the following description refers purely by way of example.
  • ski touring boots normally comprise a rigid plastic shell shaped to receive the user's foot; a front sole and rear heel made of non-slip elastomeric material; a rigid plastic leg hinged to the shell at the ankle joint; and a number of fasteners appropriately arranged on the shell and leg, and designed to grip both the shell and leg to immobilize the user's leg inside the boot.
  • the shell, housing the user's foot, of ski touring boots normally comprises an elastically deformable portion extending astride the metatarsal region of the foot, to enable the front portion of the shell to flex temporarily into a slightly curved shape, and so enable slight flexing of the sole of the user's foot.
  • the shell of ski touring boots normally comprises a controlled-deformation accordion pleat extending astride the metatarsal region of the foot to enable the tip of the shell to flex a few degrees with respect to the rest of the shell.
  • ski touring boots with an accordion pleat at the front of the shell have proved unsuitable for use in combination with the latest two-point ski-boot clamping systems, which are designed to fix the boot to the touring or telemark ski by means of two clamping jaws aligned along the longitudinal axis of the ski and designed to grip and rigidly clamp the front sole of the boot to a tip-up supporting plate hinged to and projecting from the ski, directly beneath the tip of the boot.
  • the two clamping jaws of the latest ski-boot clamping systems are located on the two ends of the tip-up supporting plate, so as to lock onto the sole of the boot : one at the tip of the boot, and the other at the arch separating the sole from the heel of the boot.
  • Arching of the sole may, obviously, be prevented by adopting a shell of high flexural rigidity, capable of opposing any elastic deformation of the sole.
  • ski touring or telemark boots with an accordion pleat at the front of the shell are designed to d o exactly the opposite, with the result that the structural rigidity imparted to the shell, and to the sole integral with it, is insufficient to ensure correct performance of the latest two-point ski-boot clamping systems.
  • a ski boot as claimed in Claim 1 and preferably, though not necessarily, in any one of the dependent Claims.
  • Number 1 in Figure 1 indicates as a whole a ski boot, in particular a specially designed, safe ski touring or telemark boot.
  • Boot 1 substantially comprises a rigid plastic shell 2 shaped to receive the user's foot; a front sole 3 and rear heel 4, made of non-slip elastomeric material and fixed in known manner to the bottom of shell 2; and a rigid plastic leg 5 shaped to receive the user's ankle and hinged to shell 2 at the ankle joint.
  • leg 5 is fixed in freely rotating manner to the two sides of shell 2 by two hinges 6 aligned along the transverse articulation axis A of the ankle, which in turn is substantially perpendicular to the mid vertical plane of the boot; and shell 2 has an elastically deformable portion 7 extending astride the metatarsal region of the foot to allow the front of shell 2 to flex temporarily into a slightly curved shape, and so enable slight flexing of the sole of the user's foot.
  • the elastically deformable portion 7 of shell 2 extends from one side to the other of shell 2, astride the metatarsal region of the foot, and almost up to sole 3, so as to separate and connect the tip portion 2a and the mid-portion 2b, both substantially rigid and undeformable, of shell 2.
  • the elastically deformable portion 7 of shell 2 comprises a controlled-deformation accordion pleat 7, which extends from one side to the other of shell 2, substantially astride the metatarsal region of the foot, and almost up to sole 3, so as to allow the tip portion 2a of shell 2 to tilt a few degrees with respect to mid-portion 2b of shell 2.
  • accordion pleat 7, i.e. the elastically deformable portion 7 of shell 2 extends along a slightly oblique, arc-shaped trajectory from one side to the other of shell 2, so that the end on the inner side of shell 2 is located ahead of the end on the outer side of shell 2 to follow the natural bend axis of the foot.
  • boot 1 also comprises a number of fasteners 8 appropriately arranged on shell 2 and leg 5, and designed to grip both shell 2 and leg 5 to immobilize the user's leg inside boot 1; and a shell clamping member 9, which, when necessary, connects tip portion 2a of shell 2 rigidly to mid-portion 2b of shell 2, to prevent any relative movement between the various parts of shell 2, and so form a rigid, substantially undeformable body of shell 2 and sole 3 integral with it.
  • Fasteners 8 are commonly known devices and therefore not described in detail.
  • this extends astride elastically deformable portion 7 of shell 2, i.e. astride accordion pleat 7, while preferably, though not necessarily, remaining coplanar with the mid vertical plane of boot 1, and comprises two supporting brackets 10 and 11 secured rigidly to the body of shell 2, facing each other on opposite sides of elastically deformable portion 7 of shell 2. More specifically, bracket 10 is secured rigidly to mid-portion 2b of shell 2, and bracket 11 is secured rigidly to tip portion 2a of shell 2.
  • clamping member 9 also comprises an articulated connecting arm 12, which extends astride elastically deformable portion 7 of shell 2, while preferably, though not necessarily, remaining coplanar with the mid vertical plane of boot 1, and is hinged at both ends to brackets 10 and 11 to rotate freely, with respect to brackets 10 and 11, about respective axes of rotation B and C, which are parallel to each other, locally tangent to the outer surface of shell 2, and substantially perpendicular to the longitudinal axis of articulated arm 12 (and therefore preferably, though not necessarily, perpendicular to the mid vertical plane of boot 1).
  • articulated arm 12 is divided into two half-arms 13 and 14, which are hinged to each other to rotate, with respect to each other, about a third axis of rotation D parallel to axes B and C, and are designed to assume a first operating configuration, in which half-arms 13 and 14 open and close freely scissor-fashion, and a second operating configuration, in which half-arms 13 and 14 are locked with respect to each other to rigidly connect supporting brackets 10 and 11 of clamping member 9, which in turn are fixed rigidly to tip portion 2a and mid-portion 2b of shell 2.
  • half-arm 13 is hinged to bracket 10 to rotate freely about axis B; half-arm 14 is hinged to bracket 11 to rotate freely about axis C; and half-arms 13 and 14 are designed to open and close freely scissor-fashion, as long as axis D is above the plane P of axes B and C ( Figure 2), i.e. as long as axis D remains on the opposite side of plane P of axes B and C with respect to shell 2, and to lock together when axis D is below plane P ( Figure 1), i.e. when axis D is located between plane P of axes B and C and the surface of shell 2, and the distance between axis D and plane P of axes B and C equals a predetermined maximum distance d o .
  • articulated arm 12 is in the first operating configuration when axis D is above plane P of axes B and C, and in the second operating configuration when axis D is below plane P of axes B ad C, at maximum distance d o from plane P.
  • boot 1 also comprises a leg clamping device 15 which, selectively and alternatively, provides for locking leg 5 rigidly to shell 2 to prevent any relative movement between the two; for clamping leg 5 to shell 2 to only permit positive oscillation of leg 5 about axis A, from a predetermined rest position towards tip portion 2a of shell 2; or for releasing leg 5 from shell 2 to allow leg 5 to oscillate freely back and forth about axis A.
  • leg clamping device 15 which, selectively and alternatively, provides for locking leg 5 rigidly to shell 2 to prevent any relative movement between the two; for clamping leg 5 to shell 2 to only permit positive oscillation of leg 5 about axis A, from a predetermined rest position towards tip portion 2a of shell 2; or for releasing leg 5 from shell 2 to allow leg 5 to oscillate freely back and forth about axis A.
  • articulated arm 12 As regards shell clamping member 9, on the other hand, the user, when necessary, presses the central portion of articulated arm 12 to push axis D below, and to maximum distance d o from, plane P of axes B and C; in which position, articulated arm 12 forms a rigid structure rigidly connecting brackets 10 and 11, and preventing any flexing of tip portion 2a of shell 2 with respect to mid-portion 2b of shell 2.
  • boot 1 provides, as required by the user, for effectively allowing flexing of the user's foot to lift the heel of boot 1 off the ski, as well as for a high degree of structural rigidity of shell 2 when using boot 1 in conjunction with the latest two-point ski-boot clamping systems.
  • articulated arm 12 is hinged to brackets 10 and 11 so that axes of rotation B and C are locally perpendicular to the surface of shell 2 and preferably, though not necessarily, coplanar with the mid vertical plane of boot 1.
  • axis of rotation D of half-arms 13, 14 of articulated arm 12 is also perpendicular to the surface of shell 2, and is movable from one side to the other of plane P of axes B and C - which plane, in this case, may coincide with the mid vertical plane of boot 1 - to lock tip portion 2a of shell 2 rigidly to the mid-portion, or to allow tip portion 2a of shell 2 to flex with respect to mid-portion 2b of shell 2.
  • shell clamping member 9 may comprise a rigid rod or brace 16, which is hinged to bracket 10 to rotate freely about an axis B' locally perpendicular to the surface of shell 2, and is movable, in a plane locally perpendicular to axis B', to and from a work position, in which it extends astride elastically deformable portion 7 of shell 2, and is positioned with its distal end 16a resting on bracket 11 and engaging a seat formed in the body of bracket 11, which is obviously located on the opposite side of elastically deformable portion 7 of shell 2.
  • brace 16 prevents any compression of elastically deformable portion 7 of shell 2, and hence any reduction in the distance between brackets 10 and 11. In other words, in the above work position, brace 16 prevents any flexing of tip portion 2a of shell 2 with respect to mid-portion 2b of shell 2.
  • shell clamping member 9 comprises a rigid rod or brace 17, which is hinged to bracket 10 to rotate freely about an axis B" locally tangent to the surface of shell 2, and is movable to and from a work position, in which it extends astride elastically deformable portion 7 of shell 2, and is positioned with its distal end 17a resting on the body of bracket 11 on the opposite side of elastically deformable portion 7 of shell 2, to prevent any further compression of elastically deformable portion 7 of shell 2, and hence any flexing of tip portion 2a of shell 2 with respect to mid-portion 2b of shell 2.
  • shell clamping member 9 also comprises a safety hand lever 18 for rigidly, firmly, but easily removably locking the distal end 17a of brace 17 to the body of bracket 11 on which it rests.
