Definitions

  • the present invention relates to a ski fastening.
  • the known ski fastenings are currently usually composed of a heel element and a tip element which are associated with the ski for the engagement of the ends of a ski boot.
  • Each of said heel and tip elements therefore has adapted and distinct adjustment means for the correct engagement, release and securing of the boot.
  • an Austrian patent application no. 190/83 filed on January 21, 1983, discloses a fastening comprising a lateral and a rear engagement elements, adjustment means for both engagement elements being provided on the rear engagement elements.
  • Said known fastening has the disadvantage of providing a common and simultaneous adjustment for the two engagement elements; such an adjustment can only be a compromise due to the different requirements of the lateral and the rear elements.
  • the aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a ski fastening which allows an optimal adjustment of the securing action between the ski and the boot.
  • an important object is to provide a fastening in which said adjustment can be performed by the skier with localized interventions.
  • Another important object is to provide a fastening in which at least one of the engagement means can have small dimensions, be structurally simple and have a simpler design from an aesthetic point of view.
  • Not least object is to provide a fastening which associates the preceding characteristics with that of being reliable and safe in use.
  • a ski fastening characterized in that it comprises at least one front and one rear engagement means for a boot, means being arranged on one of said front and rear engagement means or on said ski for the independent adjustment of said front and rear engagement means.
  • the fastening for a ski is constituted by a rear engagement means 2 and by a front engagement means 3 which are associated with the ski 100.
  • the rear engagement means 2 comprises a heel element 7 pivoted transversely at one end of a case 4 at a first pin 8 adjacent to the ski 100.
  • the heel element 7 engages the heel 5 of a ski boot 6.
  • a lever 10 is furthermore associated with the heel element 7 at the first pin 8 and at a second pin 9; by turning down the lever 10, toward the underlying ski, said heel element 7 is rotated, consequently lifting the heel 5 of the boot and therefore opening the fastening.
  • a first seat 11 for a first adjustment means 12 for the heel element 7 is furthermore defined axially within the case 4; said adjustment means is constituted by a first screw 13 which can be inserted at the rear region 14 of the case 4 and compresses a first spring 15 at a point member 16 which is axially slidable in the first seat 11 and engages an adapted cam 17 provided rearward to said heel element 7.
  • a second seat 18 for a second means 19 for the adjustment of the front engagement means 3 is defined, below the first seat 11 on the case 4.
  • Said second seat 18 is also defined axially to the case 4 along an axis which coincides with the longitudinal axis of the ski 100.
  • the head of a second screw 20 protrudes from the case 4 at said second seat 18 and at the region 14; the stem of said screw is associated with a complementarily threaded seat defined at the stem 21 of a T-shaped lug 22.
  • a pair of first pins 23a and 23b protrudes at the wings of said lug toward the front engagement means, and a second pair of springs 24a and 24b is arranged coaxially to said pins.
  • first 26 and second 27 identical levers are arranged coaxially to a pair of second T-shaped pins 25a and 25b which abut respectively at a first 26 and second 27 identical levers, each freely pivoted in a median region respectively at a third pin 28 and at a fourth pin 29 which protrude perpendicular from the base 30 of the case 4.
  • Each lever 26,27 is also freely pivoted, at its other end, to a rod 31 at a single pin which is slidable in adapted first slots 38a and 38b defined at the adjacent ends of the respective first lever 26 and second lever 27.
  • Said rod 31 is arranged approximately at the median axis of said rear and front engagement means.
  • Said front engagement means is constituted by a tip element 32 for the engagement of the front end of the ski boot 6 which is slidably associated at a base support 33, which is associated with the ski, by means of an adapted fifth pin 34 rigidly associated with the tip element 32, and is slidable at an adapted second slot 35 defined longitudinally on the base support 33.
  • said base support and the rod 31 can be extendable or retractable, for example by telescoping, or in any other suitable way, to adjust its length in order to adapt to different boot sizes.
  • the rod 31 is connected to the tip element 32 by means of a sixth pin 36 which is rigidly associated with the end of said rod 31 and is accommodated at an adapted third seat 37 provided on said tip 32.
  • Said third seat 37 is V-shaped, with its vertex directed toward the rear engagement means 2.
  • the use of the fastening is therefore as follows: initially, the skier, acting only at the rear engagement means 2, adjusts the degree of securing of the heel element 7 on the heel 5 of the boot 6 by acting at the first screw 13.
  • the front engagement means 3 is adjusted by acting again at the second screw 20 associated at the rear engagement means 2; a compression of the second pair of springs 24a and 24b corresponds to a clockwise rotation of said second screw.
  • a lateral thrust of the boot at the tip element 32 causes the sliding of the sixth pin 36 at the wings of the third seat 37, causing a translatory motion of the rod 31 toward the tip of the ski; said translatory motion leads to a compression of the second pair of springs 24a and 24b which will oppose the release of the fastening up to a preset limit.
  • the invention has achieved the intended aim and objects, a ski fastening having been obtained in which the means for the adjustment of the tip element and of the heel element can be, for example, integrated in the rear engagement means or, as an alternative, in the front engagement means or, again as an alternative, at the ski, keeping the rear and front adjustments independent and distinct.
  • the adjustment means can in fact also be provided on the ski, and this allows to locate them in a more convenient portion of the ski, where more room is available.
  • Figures 3-5 show a ski fastening 101, according to a further aspect of the invention, comprising a rear engagement means 102 and a front engagement means 103, associated with a ski 100.
  • the fastening 101 is substantially similar to the fastening 1 described above, and the rear engagement means 102 comprises a heel element 107 pivoted at a case 104 and adapted to engage the heel 5 of a ski boot 6.
  • a first adjusting means 112 comprises a first spring 115, adjusted by a first screw 113, and biasing a point member 116 against a heel cam 117 formed on the heel element 107.
  • a second adjusting means 119 comprises a shaft 121 having a first end 140 connected to a portion 130 of the fastening structure, and a second end inserted and abutting in a hole of a second screw 120.
  • the screw 120 has an external threading engaged with a slider 141 in such a way that, by turning the screw 120, the slider 141 slides with respect to the case 104.
  • a second spring 124 is coaxially arranged on the shaft 121, between the slider 141 and a pusher 125 which can freely slide on the shaft 121.
  • the shaft 121 also has a flange 142 and a third spring 129, arranged between the flange 142 and a portion 144 of the case, for biasing the shaft 121 in abutment with the screw 120.
  • a pair of cams 126 is arranged at the pusher 125, each cam 126 being pivoted, by means of a pivot 127, to the case 104.
  • Each cam 126 has an upper section 128 abutting against the pusher 125, and a lower fork section 145 engaging a transverse cam pivot 138.
  • the cam pivot rod 138 is associated with a longitudinal rod 131 connected with the front engaging means 103. Turning the adjusting second screw 120, adjusts the biasing force of the second spring 124 against the pusher 125, which contrasts the clockwise rotation (with reference to figure 4) of the cam 126 moved by the leftward motion of the rod 131.
  • the front engagement means 103 comprises a tip element 132 pivoted to a base support 133 and adapted to rotate according to a transverse horizontal axis 150 and according to a vertical axis 151.
  • the tip element comprises a horizontal pin 137 which engages a second cam member 136 connected to the longitudinal rod 131. It is apparent that when the tip element is forced to rotate, in the direction of arrows 152 or 153, for example, the pin 137 pushes the cam member 136 toward the left, as indicated by the arrow in figure 4, therefore moving the longitudinal rod 131 rightward.
  • the operation of the fastening 101 is substantially similar to the operation of fastening 1 described above.
  • Figures 7-8 schematically illustrates a fastening 201, according to a further aspect of the invention, comprising a rear engagement element 202 and a front engagement element 203, and wherein the first and second adjusting means, respectively 212 and 219, are associated with the front engagement means 203.
  • the first adjusting means 212 acts on the tip element 232 and the second adjusting element 219 acts on the heel element 207, by means of the longitudinal rod 231, substantially as described above.
  • FIG 9 schematically illustrates a ski fastening 301, according to still a further aspect of the invention, comprising a rear engagement element 302 and a front engagement element 303, and wherein the first and second adjusting means, respectively 312 and 319, are contained in a casing 304 arranged on the ski 100, behind the rear engagement element.
  • the first adjusting means 312 acts on the heel element 307, by means of a first longitudinal rod 331a
  • the second adjusting means 319 acts on the tip element 332, by means of a second longitudinal rod 331b.
  • the fastenings 201 and 301 respectively illustrated in figures 7,8 and 9, also substantially operate as described above in detail.
  • the materials, as well as the dimensions, may also be the most appropriate according to the specific requirements.
