Definitions

  • the present invention relates to a ski boot, and in particular to a ski boot with an upper quarter connected to the front quarter for dampening the impact between a skier's tibia and the quarter of the ski boot.
  • the quarters are connected to the shell in such a manner that they can oscillate about a horizontal axis extending perpendicular to the longitudinal extension of the base of the shell.
  • the amount of flexibility of a boot is, in general, very limited, and has a point which defines the limit of oscillation which, in some cases, causes an impact between a skier's leg and the quarter of the boot, as the quarter itself can not continue to rotate.
  • the dampening action derives solely from a secondary phenomenon of the structure of the boot, and consequently it is not optimal.
  • a ski boot is illustrated which, at the upper edge of the front quarter, has a cut-out wherein a distribution plate or curved plate is located which covers the cut-out and which is articulated, at a middle portion thereof, about an axis extending transversely with respect to the longitudinal extension of the quarter and which is supported by the quarter itself.
  • the plate positions itself at the zone where the tibia of the leg rests, so as to always maintain the same angular orientation assumed by the leg of the skier and thus providing a distributed support zone and not concentrated on the edge line.
  • the plate is contained, at least for a large zone of its lateral portions, at the interior of the quarter and exerts a scraping action on the quarter itself, which, by virtue of the intrinsic elasticity, determined by the material of which the quarter is made, causes an elastic biasing action more or less determined by the degree of flexion movement, which biasing action tends to move the plate towards its initial rest position.
  • the aim of the invention is indeed that of solving the above mentioned problems by providing a ski boot in which it is possibile to elastically dampen the impact between the leg and the quarter without influencing the selectable degree of flexibility of the quarter.
  • Another object of the present invention is to provide a ski boot wherein the features of shock absorption or dampening do not require structural complications in the ski boot itself.
  • a not least object of the present invention is that of providing a ski boot, which can be easily manufactured, and which is advantageous from a purely economical point of view.
  • a ski boot comprising a shell whereto are connected a front quarter and a rear quarter, characterized by the fact that it comprises an upper quarter, articulated to said front quarter and positioned at least partially at a lowered zone of the front upper edge of said front quarter, there also being provided, means for connection of said upper quarter to said rear quarter.
  • the ski boot comprises a shell 1 whereto are connected, in a per se known manner, a front quarter 2 and a rear quarter 3.
  • the peculiarity of the invention is constituted by the fact that it comprises an upper quarter 10 which is positioned substantially at a lowered zone 11 of the front upper edge of the front quarter 2.
  • the upper quarter 10 is oscillable with respect to the front quarter 2 and may be hinged by means of a pin 12 or similar elements, which are positioned at the front part of the quarter or by means of a lateral hinge connection provided at the lower part of the upper quarter 10.
  • the upper quarter 10 is also connected to the front quarter 2 by means of pegs 15, which are preferably fixed to the front quarter 2 in a lateral position and which engage in elongate slots 16 correspondingly formed on the upper quarter 10.
  • the pegs 15 are slideably held within the slots 16, and more precisely the slots slide with respect to the pegs since the pegs are fixed on the front quarter 2 in a lateral positon.
  • the upper quarter 10 is associated, through connection means constituted by cables 20, with an actuating lever 21 fixed to the front quarter and operable for exerting the desired traction force on the cables.
  • the cables which practically act as a pulling element, may be connected to any point of the upper quarter, the upper quarter may be positioned either internally or externally of the front quarter; in the case wherein the upper quarter is located externally the cables will pass externally of the front quarter.
  • shock absorbing action or dampening of the impact is in practice obtained by exploiting the elastic action exerted by the forward flexure of the rear quarter as pulled by the cables.
  • the upper quarter 10 is associated, at its upper part, to the front quarter 2 by means of bosses or pins 25 fixed to the front quarter in a lateral position and engaging with holes or apertures 26 which are defined in the thickness of the upper quarter 10.
  • elastic shock absorbing means are provided which act between the front quarter and the upper quarter 10 and which advantageously are constituted by sectors 31 made of elastic material such as rubber or the like.
  • the sectors 31 are housed in the apertures 26, within the thickness of the upper quarter 10, and engage with the bosses 25.
  • connection determined through the elastic sectors 31, is such that, when the leg is flexed forwards to abut against the upper quarter, there is generated a rotational movement of the upper quarter 10 about the pin 12 with respect to the front quarter 2, with the consequent compression of the sector 31 on the bosses 25, consequently obtaining an elastic dampening of the impact.
  • the sectors 31 are advantageously located to define a semi-circumferential portion and engage with part of the bosses 25 facing the rear quarter.
  • the invention fully achieves the proposed aim and objects, and in particular it will be noted that the invention offers the possibility of dampening the impact which is created by a forward flexure, between the tibia and the front quarter,through the exploitation of elastic means which may be constituted by the intrinsic elasticity of the rear quarter connected to the upper quarter or by the elastic sectors introduced within the holes 26 .
