Definitions

  • the present invention relates to a cross-country ski fastening.
  • ski fastenings are currently known for the practice of cross-country skiing; the known ski fastenings generally have the essential feature of locking the tip of an adapted shoe to the ski.
  • Said tip is provided as an extension of the sole of the shoe and deforms elastically during the stride, and this allows to adopt the so-called alternated step technique.
  • This technique in fact allows better efficiency in skiing if the ski can be placed edgewise with respect to the plane of the snow, imparting to said ski a lateral movement according to an axis which is oblique with respect to the advancement axis.
  • fastenings which are essentially constituted by two elements, one suitable for locking the tip of the shoe and the other adapted to lock the heel region.
  • One of said coupling means is pivoted to the plate, has means for adjusting its oscillation with respect to said plate and cooperates with locking means adapted to make it temporarily associable with the base which can be coupled to the ski.
  • the aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a cross-country ski fastening which allows the skier to adopt both the alternated step technique and the side push step technique and is at the same time structurally very stable so as to allow the optimum transmission of efforts from the shoe to the ski.
  • an important object is to provide a cross-country ski fastening with an easier axial and transverse locking of the shoe with respect to the ski.
  • Another important object is to provide a fastening which associates with the preceding characteristics that of allowing a rapid and optimum coupling and uncoupling of the shoe.
  • Another object is to provide a fastening which is structurally simple and does not require particular maintenance.
  • Not least object is to provide a fastening which associates with the preceding characteristics that of being reliable and safe in use.
  • a cross - country ski fastening comprising a base which can be coupled to a ski, a plate being transversely and freely pivoted to one end of said base, characterized in that said plate is transversely provided with at least one point of engagement with the sole of a shoe and, specularly to the longitudinal axis, with at least two brackets to which at least two lateral jaws for coupling to complementarily shaped grip elements defined on said sole are articulated, said fastening further comprising means for adjusting the oscillation of said at least two jaws with respect to said plate.
  • said at least two jaws can be arranged on the plate along axes which are mutually parallel, divergent or convergent toward the front part of the ski.
  • said at least one point of engagement with the sole of the shoe is conveniently located approximately at the tip of said shoe, whereas if the jaws converge toward the front part of the ski said at least one engagement point is located proximate to the end of said plate which is opposite to the pivoting end of said plate to said base.
  • the fastening generally indicated by the reference numeral 1, comprises a planar base 2 which can be coupled at the surface of a ski 3.
  • a pair of first lateral shoulders 4a and 4b advantageously arranged specularly with respect to the longitudinal median axis of said planar base 2, protrude from said planar base 2 proximate to its end directed toward the tip of the ski 3.
  • a plate 5 is freely and transversely pivoted to the end of said first lateral shoulders 4a and 4b and extends in the opposite direction with respect to that of the tip of the ski 3.
  • Said plate has at least one point of engagement with the sole 6 of a shoe 7 for cross-country skiing; said point is advantageously constituted by a first wing 8 which protrudes perpendicular from an end of said plate; said first wing 8 advantageously has a curved configuration.
  • said first wing has a concavity directed toward the rear end of the ski 3 (as shown in figure 1); if said wing 108 protrudes from the opposite end, the' concavity is instead directed toward the tip of said ski 103, as shown in figure 5 wherein similar elements are designated by reference numeral added by 100, with reference to figure 1.
  • a complementarily shaped first transverse seat 9 for the first wing 8 is naturally provided at the sole 6.
  • a first pair of brackets 10a and 10b and a second pair of brackets 11a and 11b protrude from said plate 5 laterally and specularly to said plate's longitudinal median axis.
  • the first pair of brackets is adjacent to the first lateral shoulders 4a and 4b, whereas the second pair of brackets is instead adjacent to the opposite end of the plate 5.
  • a first jaw 12 and a second jaw 13 which have the same configuration and are arranged approximately specularly to the longitudinal median axis of the plate 5 are articulated at the ends of each of said first and second pairs of brackets.
  • Said first and second jaws have a plurality of tabs, indicated by the numerals 14a and 14b, which have a substantially wedge-like shape and are directed toward the longitudinal median axis of said plate 5.
  • Said tabs constitute means for coupling to complementarily shaped grip elements defined on said sole 6; said grip elements are constituted by complementarily shaped seats 15a and 15b defined laterally to the sole 6.
  • the axes of said first jaw 12 and said second jaw 13 can diverge toward the front part of the ski 3: in this case the engagement point, constituted by the first wing 8, is arranged approximately transversely to the plate 5 at said first lateral shoulders 4a and 4b.
  • Figure 7 illustrates a different arrangement of the axes of the first jaw 212 and of the second jaw 213, which converge toward the front part of the ski 203, not illustrated.
  • the engagement point constituted by the first wing 208 can be arranged at the end of the plate 205 which is directed toward the front part of the ski, optionally also including said first lateral shoulders 4a and 4b, not illustrated in the figure.
  • said engagement point can be provided, as illustrated in figure 5, at the end of the plate 105 which is adjacent to the second pair of brackets 111a and 111b.
  • first jaw 312 and the second jaw 313 can have their axes arranged mutually parallel, as illustrated in figure 8.
  • Figures 9 and 11 schematically illustrate the plate 405, in which the first jaw 412 and the second jaw 413 have their axis of rotation with respect to the first and second pair of brackets inclined with respect to the plane of arrangement of the ski 403 by an angle A which is smaller than 90 degrees, assuming as positive a counterclockwise direction of rotation starting from the front part of the ski 403.
  • the point of engagement with the sole of the shoe can be located at one of the transverse ends of the plate 405, 505.
  • the fastening furthermore comprises means for the adjustment of the oscillation of the first and second jaws; said means are constituted by a first pair of springs 16a and 16b and by a second pair of springs 17a and 17b.
  • Each of said first and second pairs of springs is arranged along transverse axes with respect to the plate 5 and are interposed, on planes which are approximately mutually parallel, between said first jaw 12 and said second jaw 13 and a facing pair of plates 18a and 18b which have a wedge-like configuration at their mutually facing surfaces.
  • each of said first and second pairs of springs are advantageously accommodated at adapted seats provided on the facing surfaces of said first jaw 12 and plate 18a and of said second jaw 13 and plate 18b.
  • the means for adjusting the oscillation of said first and second jaws with respect to the plate 5 furthermore comprises an adapted first screw 19 which is arranged approximately axially to said plate 5 and interacts with a pair of first nuts 20a and 20b.
  • the wedge-like lateral surfaces of the nuts 20a, 20b are shaped complementarily to the facing surfaces of said pair of plates 18a and 18b and interact therewith.
  • the rotation imparted to the screw 19 actuates the mutual approach or spacing of said nuts 20a and 20b and thus forces a movement' of the pair of plates 18a and 18b toward the first and second jaws or in the opposite direction, thus compressing the first and second pairs of springs or allowing their elongation.
  • the fastening furthermore includes means for contrasting the oscillation of the plate 5 with respect to the base 2; said means are constituted by a third spring 21 which is coiled at the pin 22 for pivoting the plate 5 to the first lateral shoulders 4a and 4b of the planar base 2 and has a first end, which interacts with an adapted raised portion 23 which protrudes transversely to the first wing 8 which constitutes the point of engagement with the sole of the shoe, and a second end which rests at the base 2 toward the front portion of the ski.
  • said means are constituted by a third spring 21 which is coiled at the pin 22 for pivoting the plate 5 to the first lateral shoulders 4a and 4b of the planar base 2 and has a first end, which interacts with an adapted raised portion 23 which protrudes transversely to the first wing 8 which constitutes the point of engagement with the sole of the shoe, and a second end which rests at the base 2 toward the front portion of the ski.
  • a means is provided for adjusting the contrast to the oscillation of the plate with respect to the base; said means is constituted by a second screw 24 the stem whereof is rotatably associated at a second wing 25 which protrudes from said base 2 and is associated with a second nut 26 which is associated with said base and interacts with the surface of the end of the third spring 21 adjacent to the base 2.
  • the invention has achieved the intended aim and objects, a cross-country ski fastening having been provided with which the sole of a shoe is stably associable so as to allow the optimum transmission, on the part of the skier, of the efforts from the shoe to the ski and which thus allows said skier to adopt the side push step technique as well as the alternated step technique.
  • the point of engagement and the particular configuration given to the first and second jaws provide in fact the best axial transverse locking of the sole of the shoe.
  • the means adapted to adjust the oscillation of the first and second jaws furthermore allows to achieve an optimum coupling and/or release of the shoe from the fastening.
  • the adjustable means for contrasting the oscillation of the plate with respect to the base allow the skier to select the maximum elevation of the plate with respect to the base according to his own requirements by means of a simple and compact structure.
