Definitions

  • the present invention relates to a downhill skiing or ski touring boot equipped with an improved skiing-walking selection mechanism.
  • such boots include a leg portion, which hugs the tibial portion of the user's leg and is hinged to a foot portion, which instead contains the user's foot and is fitted with a sole.
  • the leg portion is perfectly secured to the foot portion, that is to say it does not rotate in relation thereto, allowing for precise and safe skiing.
  • the leg portion In the walking configuration, the leg portion is unlocked in relation to the foot portion: the rotation of the leg portion in relation to the foot portion thus ensures better and more comfortable walking compared to traditional boots, as it follows the natural rotation of the ankle.
  • the rotation of the leg portion may be locked and unlocked by reversibly fixing the leg portion to the foot portion.
  • the passage from the walking configuration to the skiing configuration should be as quick and as easy as possible because the skier, during downhill skiing, has to switch between the two configurations many times, depending on the route to be taken.
  • Some solutions of the prior art provide that the movement of the main selection lever, which is designated for switching from the skiing configuration to the walking configuration and vice versa, is also operatively connected to the adjustment levers of the leg portion and/or of the foot portion of the boot. In this manner, when the main selection lever is positioned for opening, that is, the leg portion is unlocked so that it may rotate in relation to the foot portion, the adjustment levers for the leg portion and/or the foot portion open or in any case are loosened.
  • This configuration allows for greater comfort for the user since, with a single movement of the main lever, it may move into the skiing configuration, in which the leg portion is locked in rotation and the adjustment levers are all correctly tensioned, and also into the walking configuration, in which not just the leg portion is free to rotate, but at the same time the adjustment levers are open, allowing a greater freedom of movement of the foot and of the tibial portion in relation to the boot during the walk.
  • opening the adjustment lever of the leg portion and/or of the foot portion makes it so that, when the user has to return to the skiing position, the mechanism is not able to recover the previous adjustments of said adjustment levers.
  • the main reason is due to the fact that, once opened, the adjustment levers tend to unhook with respect to the related racks, for which reason the user is then subsequently forced to restore, by trial and error, the correct tension of said adjustment levers.
  • the purpose of the present invention is to provide a downhill skiing/ski touring boot that solves the aforementioned disadvantages with respect to the known art.
  • reference sign 4 denotes a ski boot in its entirety, comprising a lower part or foot portion 8 suitable for enclosing the user's foot, and an upper part or leg portion 12 suitable for enclosing the lower part of the skier's leg.
  • ski boot means a boot for downhill skiing, ski touring, or even a boot of the "Telemark” type.
  • foot portion and leg portion should also be considered in a general and non-restrictive way: the present invention does not have any kind of limitation with respect to the shapes, sizes, materials, or type of leg portion and foot portion, and therefore types of leg portion and foot portion that at least partially enclose the foot and lower part of the leg, especially the skier's shin, are also covered by the invention.
  • the leg portion 12 is hinged to the foot portion 8 so as to rotate in relation to the foot portion 8 around hinges 16 which define a rotation axis X-X.
  • the leg portion may rotate forwards, towards a tip 20 of the boot 4, and backwards, towards the rear or heel 24 of boot 4.
  • hinge 16 may be different; preferably there are two hinges 16 arranged on opposite sides with respect to the leg portion 12.
  • the hinges 16 identify a rotation axis X-X that may, in one embodiment, be horizontal, that is to say parallel to the sole 26 of the boot 4.
  • the leg portion 12 comprises a selection lever 28 suitable for selectively locking and/or unlocking the rotation of the leg portion 12 in relation to the foot portion 8, depending on whether the user wishes to pass from the skiing configuration to the walking configuration, respectively.
  • leg portion 12 In the skiing configuration the leg portion 12 will be locked in relation to the boot 4, while in the walking configuration the leg portion 12 will be free to rotate back and forth, around the relevant hinges 16, so as to accommodate, to the greatest possible extent, the natural rotation of the user's ankle.
  • the leg portion 12 is provided with at least one adjustment lever 32 that is operatively connected to at least one hook 36 which may be engaged on teeth 40 of a rack 44.
  • the adjustment lever 32 and the rack 44 are fixed to opposite flaps 48, 52 of the leg portion 12 which are mutually closable in a known way.
  • the at least one adjustment lever 32 is operable in rotation so as to mutually approach or distance said flaps 48, 52 of the leg portion 12 from each other, based on the mutual position between the hook 36 and the tooth 40 of the rack 44 on which said hook 36 is engaged.
  • the selection lever 28 is operatively connected to means 56 for locking/unlocking the rotation of the leg portion 12 in relation to the foot portion 8.
  • the selection lever 28 is operatively connected to a support 60 and to a post 64 which may be engaged in abutment against a peg 68 fixed to the foot portion 8.
  • the selection lever 28 and the post 64 are integral with the leg portion 12, while the peg 68 is integral with the foot portion 8.
  • the peg 68 is a cylindrical element arranged along a transverse direction T-T substantially perpendicular to the post 36.
  • Said transverse direction T-T may be, for example, parallel to and offset from the rotation axis X-X defined by the hinges 16.
  • the selection lever 28 in the passage from the opening configuration to the closing configuration, mutually distances the support 60 and the post 64 from each other, placing an abutment end 72 of the latter against the peg 68 to prevent a rotation of the leg portion 12 backwards, towards the heel 24.
  • the abutment end 72 of the post 64 is at least partially counter-shaped with respect to the peg 68 and the selection lever 28 is kinematically connected to the post 64 by means of a connecting rod 76.
  • the foot portion 8 comprises at least one end-stroke (not shown) in the forward rotation of the leg portion 12.
  • the leg portion 12 comprises at least one end-stroke (not shown) in the forward rotation towards the foot portion 8.
  • the selection lever 28 is operatively connected to said at least one adjustment lever 32 and/or to said rack 44 in such a way as to bring the flaps 48, 52 of the leg portion 12 closer together when arranged in a skiing configuration and, vice versa when arranged in a walking configuration.
  • the adjustment lever 32 is slidably mounted on a base 80 fixed to one of said flaps 48, 52 of the leg portion 12, wherein the selection lever 28 is operatively connected to the adjustment lever 32 so as to cause the translation thereof in relation to said base 80.
  • the rack 44 is slidably mounted on a base 80 fixed to one of the flaps 48, 52 of the leg portion 12, wherein the selection lever 28 is operatively connected to the rack 44 so as to cause the translation thereof in relation to said base 80.
  • the selection lever 28 is operatively connected to said at least one adjustment lever 32 and/or to said rack 44 by means of at least one cable or rope 84, so as to pull the cable or rope 84 in the passage from the opening configuration to the closing configuration of the selection lever 28.
  • opening the selection lever 28 simultaneously allows the rotational unlocking of the leg portion 12 in relation to the foot portion 8 so as to allow walking, and also the loosening of the adjustment lever 32 of the leg portion 12 and/or of the foot portion 8 to further facilitate walking and make it more comfortable/ergonomic.
  • This loosening in fact, makes it possible to distance the flaps 48, 52 from each other.
  • closing the selection lever 28 simultaneously allows the rotational locking of the leg portion 12 in relation to the foot portion 8 so as to allow skiing, and also the closing or the tensioning of the adjustment lever 32 of the leg portion 12 and/or of the foot portion 8.
  • This closing in fact, makes it possible to bring the flaps 48, 52 closer together.
  • the selection lever 28 is operatively connected to a plurality of adjustment levers 32 and/or racks 44, said operative connection being of the parallel type.
  • the leg portion 12 is provided with a flexible upper closing band (not shown) that is operatively connected to said selection lever 28.
  • Said flexible upper closing band is provided, for example, with Velcro ® closing means.
  • the leg portion 12 is free to rotate around the respective hinges 16, along the axis of rotation X-X.
  • the rotational movement of the leg portion 12 will be guided by the rotation of the user's ankle.
  • the loosening of the adjustment levers 32 of the leg portion 12 and/or of the foot portion 8 subsequent to the opening of the selection lever 28 further facilitates the walking and renders it more comfortable/ergonomic, since this loosening makes it possible to distance the flaps 48, 52 from one another.
  • the adjustment levers 32 reduce their pulling since the adjustment lever 32 or the rack 44 is able translate on the related bases 80 in such a way as to increase the distance between said flaps 48, 52.
  • the post 64 When the selection lever 28 is moved to the closing position, the post 64 places its abutment end 72 against the peg 68 in such a way as to block the rotation of the leg portion 12 towards the heel 24.
  • the adjustment levers 32 increase their tightening since the adjustment lever 32 or the rack 44 is able to translate on the related bases 80 in such a way as to bring said flaps 48,52 together.
  • Independent adjustment in this case means that the tightening of one adjustment lever 32 does not have an influence on the tightening of the other and vice versa.
  • the present invention overcomes the drawbacks of the prior art.
  • the present invention makes it possible to smoothly pass from the skiing configuration to the walking configuration with the simple operation of a single selection lever operatively connected both to the locking/unlocking means and to the adjustment levers of the boot.
  • the operative connections between the selection lever and the plurality of adjustment levers is in parallel, not in series.
  • the closing forces applied by the adjustment levers are independent of one another, and therefore, despite the repeated operations of the selection lever, the boot always maintains the same level of adjustment and tensioning given in an independent manner by the individual adjustment levers.
