Definitions

  • the present invention relates to the technical field of ski mountaineering.
  • the present invention relates to a ski boot for ski mountaineering.
  • ski boots for ski mountaineering comprising two retractable pins at opposite side walls in the respective front portion, which are apt to engage a toe of a ski mountaineering coupling which is provided with suitable through holes.
  • EP 1 249 183 A1 discloses a ski boot with a pair of immobile front pins and a pair of movable rear pins, respectively engaging holes of a toe piece and holes of a rear piece. The rear pins are biased toward a protruding position, but can be retracted when the user pulls a handle.
  • the ski boot is provided with suitable seats inside which the corresponding bushes are housed, at said opposite front side walls.
  • Elastic means associated to the pins are arranged inside the bushes, to act on the pins by stressing them outwards of the seat. It is known that, for practicing ski mountaineering, when the skier is going downhill the respective ski boots are to be able to be disengaged from the corresponding couplings in case of stresses (for example if the skier falls down).
  • the lever does not intercept the pins when the skier is going to go climbing: in this way, the pin can engage the corresponding hole in the toe in not removable manner, thus allowing the ski boot to oscillate with respect to the toe according to a cross axis thereto.
  • said ski boots strictly need couplings provided with means for acting, from outside inwards, on the pins of the ski boots, so that the action of the elastic means is hindered.
  • Such means which for example comprise a couple of levers, are quite cumbersome and have a negative effect on the whole weight of the group formed by ski boot and coupling.
  • Such means are subjected to impacts, which can lead to the damage thereof or to the fall of the skier.
  • the pins can be damaged accidentally as well; in fact, when the ski boot is disengaged from the corresponding coupling, they are stressed outside of the seat by the elastic means, and so, they are exposed to impacts.
  • a similar situation occurs for example when, the skis being removed and put on the shoulders, a skier walks on a rock route or is climbing: it is clear that the ski boot can impact on a rock, thus damaging a pin. Once the pin is damaged, it will be hardly able to be disengaged from the corresponding seat again, or however to engage it optimally.
  • Aim of the present invention is to overcome the just described drawbacks.
  • the ski boot for ski mountaineering proposed with the present invention solves the drawbacks of the prior art.
  • the proposed ski boot does not need couplings provided with levers or other means as cumbersome as the ones known, and reduces significantly the weight of the group formed by coupling and ski boot with respect to the current state of art.
  • the user can act easily on the control means, for example by means of a ski stick to arrange the assembly ski boot-coupling for a downhill, a climbing, or for disengaging the ski boot from the coupling (by acting through the control means on the front pins, and according to a variant, on the rear pins as well).
  • the pins of the proposed ski boot are not exposed to impacts when the ski boot is disengaged from the corresponding coupling (for example when the user is climbing or walks on a rock route).
  • the pins can be kept in the corresponding seats, thus avoiding to be subjected to damages, which often occurred in prior art.
  • the ski boot (1) comprises: a couple of front pins (P1), provided in the front portion (A) of the ski boot (1) at opposed side walls, apt to engage corresponding holes of a toe (K) for ski mountaineering; a couple of front seats (2), provided in the front portion (A) of the ski boot (1), each one receiving one of the front pins (P1) (see for example fig. 2A ).
  • Each front pin (P1) is movable in the corresponding seat (2) to assume: a climbing configuration (when the user has to go climbing), in which it projects from the corresponding seat (2) to engage in not removable manner a hole of a toe (K) for ski mountaineering and to allow the ski boot (1) to oscillate with respect to the axis of the same front pin (P1); a downhill configuration (when the user has to go downhill), in which it projects from the corresponding seat (2) to engage removably a hole of a toe (K) for ski mountaineering; and a disengaging configuration (when the user has to disengage the ski boot (1) from the corresponding coupling) in which it is in the corresponding seat (2) so that it is disengaged from the hole of the toe (K).
  • the ski boot (1) comprises: control means (4); first connection means (5, 50) housed at least partially in the ski boot (1) and connected to the front pins (P1) and to the control means (4).
  • control means (4) are constrained to the first connection means (5, 50) so that they can assume: an operating position, in which they act on the first connection means (5, 50) so that the front pins (P1) are moved in the respective climbing configuration (see figs. 1-3 , 2A , 3A , 18-20 , 19A, 20A ); an intermediate position in which they act on the first connection means (5, 50) so that the front pins (P1) are moved in the respective downhill configuration (see fig. 4-6 , 5A , 6A , 21-23 , 22A, 23A ); and a not operating position in which they act on the first connection means (5, 50) so that the front pins (P1) are moved in the respective disengaging configuration (see figs. 7-9 , 8A , 9A , 24-26 , 25A, 26A ).
  • the first connection means (5, 50) are shaped so that, when the front pins (P1) are in the downhill configuration and the ski is subjected to a stress higher than a critical one, the front pins (P1) are disengaged from the respective hole of the toe (K), thus allowing the ski boot (1) to be disengaged from the toe (K).
  • a user can easily arrange the ski boot (1) for use, when he is going to go climbing, downhill, or can disengage the ski boot from the corresponding coupling.
  • a user can act on the control means (4) by means of a ski stick; such aspect is particularly practical.
  • ski boot (1)-toe (K)assembly is less cumbersome and less heavy than prior art.
  • the ski boot (1) comprises first elastic means (3) associated to the first connection means (5, 50).
  • such first elastic means (3) provide that the ski boot (1) is disengaged from toe (K) in case the ski is subjected to a stress higher than a critical one.
  • the first connection means (5, 50) comprise a first bar element (5) (see figs. 2A, 3A , 19A, 20A ) comprising at least an end portion (15) and a body portion (16); the first bar element (5) is constrained through the end portion (15) to the control means (4) so that by moving these last ones, the first bar element (5) is moved consequently along its own axis (or possibly a direction parallel to its own axis), to determine the movement of the front pins (P1).
  • a first bar element (5) see figs. 2A, 3A , 19A, 20A
  • the first bar element (5) is constrained through the end portion (15) to the control means (4) so that by moving these last ones, the first bar element (5) is moved consequently along its own axis (or possibly a direction parallel to its own axis), to determine the movement of the front pins (P1).
  • the first bar element (5) is moved inside the ski boot (1) when the control means (4) are brought from the respective not operating position (disengaging situation) to the respective intermediate position (downhill situation) or to the respective operating position (climbing position); vice versa they are moved outwards of the ski boot (1).
  • the first elastic means (3) are associated to the first bar element (5) so that it is stressed inwards of the ski boot (1).
  • the first elastic means (3) allow the ski boot (1) to be disengaged from the respective coupling when the user is going downhill and the ski is subjected to a determined stress (for example following a fall).
  • the first bar element (5) is a wire.
  • the first bar element (5) can work in traction and pressure.
  • the first elastic means (3) are not needed to allow the ski boot (1) to be disengaged from the toe (K) in case during a downhill the ski is subjected to a stress higher than a critical one.
  • the front seats (2) are communicating with respect to each other and define a first channel (20) in the front portion (A) of the ski boot (1) (see figs. 2A , 5A , 8A , 19A , 22A , 25A ).
  • the first connection means (5, 50) comprise further: two first piston rod elements (50), each one hinged through a first end to the body portion (16) of the first bar element (5), and associated through the second end to a front pin (P1).
  • the two first piston rod elements (50) are arranged so that by moving the control means (4), the respective second ends approach and move away mutually in the first channel (20) to determine the movement of the front pins (P1).
  • the first two piston rod elements (50) are hinged around the same axis passing through the first bar element (5) and are arranged obliquely thereto.
  • the second ends of the two first piston rod elements (50) move away mutually when the control means (4) are brought from the respective not operating position (disengaging situation) to the respective intermediate position (downhill position) or to the respective operating position (climbing position); vice versa they mutually approach.
  • the first piston rod elements (50) are arranged symmetrically with respect to the development axis of the first bar element (5) (see figs. 2A , 5A , 8A , 19A , 22A , 25A ).
  • the second ends of the first two piston rod elements (50) are articulated to the first front pins (P1) (see figs. 2A , 5A , 8A , 19A , 22A , 25A ).
  • the first connection means (5, 50) can comprise two first connection elements (for example shaped as pin or piston), arranged in the first channel (20), each one connected to a front pin (P1) and to the second end of a first piston rod element (50).
