Definitions

  • the present invention relates to the technological sector of skis and the associated accessories which allow optimum performance to be achieved in all the sporting disciplines of downhill skiing. More particularly, the invention relates to an assembly consisting of ski, ski-boot and associated bindings in which one or more weights of variable size are mounted on the ski in order to achieve better balancing of the ski itself and a reduction in the vibrations of its various parts caused by the fact that the pressure stresses acting on the zone of bearing contact of the ski with the snow change continually and very rapidly as regards the intensity and the point of application.
  • skis are known where one or more weights are applied in predefined positions which, however, are determined to a large extent by the respective manufacturers.
  • inertial masses of variable magnitude are arranged along the ski, but no particular teaching is provided as regards the magnitude of these masses and the points where they are applied.
  • weights may to a certain extent improve the performance of a ski but, not having thoroughly analysed the physical problem to be solved, leaves it to the user to determine in each case the size of the weights and their location on the basis of his/her personal sensations.
  • the patent US-A-5203583 also envisages the arrangement of several masses and determines the weight, in grammes, of each of them and the points where they are to be arranged, but these teachings, since they relate to the ski only and do not refer to the ski/ski-boot/binding assembly, do not allow one to obtain advantages irrespective of the type of ski-boot used, its weight, the weight of the bindings and the weight of the ski.
  • the inventors of the present invention have defined in an objective manner a precise criterion for determining the magnitude of the abovementioned weights and their location. They have in fact found that, during a descent, the entire ski-boot/ski/bindings assembly is subject to a rotation both about the longitudinal axis of the ski and in a vertical plane about the point where the weight of the ski, ski-boot and associated bindings (as well as the skier him/herself) bear on the ground.
  • This point coincides substantially with the point of attachment of the ski-boot on the ski and is located inside the zone of the bindings, in an approximately central position.
  • the inventors have therefore determined that, in order to reduce the vibrations of the two parts of a ski situated "upstream" and "downstream" of the abovementioned point of attachment, it is necessary to reduce to a minimum the magnitude of the masses of these parts which, as a result of the associated moment of inertia, may amplify the vibrations thereof generated during the abovementioned rotational movements and acting both individually and in combination with each other.
  • weights preferably only one, as will be seen below
  • a weight and location such as to ensure that the centre of gravity of the ski/ski-boot/bindings assembly coincides with the already mentioned point of attachment.
  • the tail part of the ski is substantially shorter and has a mass which is smaller than that of the tip part such that the centre of gravity of the assembly is displaced towards the tip of the ski, slightly beyond said point of attachment.
  • the preferred solution proposed by the inventors is therefore that of applying a single weight in the vicinity of the tail of each ski so as to cause the centre of gravity of the ski/ski-boot/bindings assembly to coincide substantially with the point of attachment.
  • weights may also be applied onto the same ski, with one always being applied so as to obtain the result described above.
  • the present invention therefore relates to an assembly consisting of ski, ski-boot and bindings as described in the preamble of the accompanying Claim 1 and characterized by that described in the characterizing part of the same claim.
  • FIG 1 shows an assembly 10 according to the present invention: a ski-boot 2 is fixed onto bindings 3 (usually a plate) integral with the ski 1.
  • the upper side of the ski in the vicinity of its tail 1c, has fixed to it a weight 4i consisting of a casing 5 which is fixed by means of screws or the like onto the ski 1 and containing, inside it, a plate 6 (Fig. 3) which has compartments 7n, each of which is shaped so as to house, inside it, without substantial play, a body 8n which is preferably made of metal and has a matching shape and predefined weight.
  • the arrow F in Figure 3 shows how a body 8n is inserted into a compartment 7n).
  • each body 8n and/or the number of bodies 8n inserted into the abovementioned plate 6 may be varied, depending on the weight of the individual parts 1, 2, 3, forming the assembly 10 in each example of application, so as to cause the centre of gravity G of the assembly 10 to coincide with the said point of attachment A of the bindings 3 on the ski 1.
  • both the plate 6 and the casing 5 may be made using one of the numerous synthetic resins known to persons skilled in the art.
  • the overall weight of the mass 4i applied onto the tail part 1c of the ski 1 must consequently be increased (example not shown in the figures) so as to ensure always that the said point of attachment A coincides with the centre of gravity of the assembly.
