Definitions

  • the present invention relates to a ski device.
  • Known skis currently have a variously configured internal structure, the function of which is to obtain the best compromise between a flexible ski, so as to adapt to the configuration of the snow surface while skiing, and a ski which is at the same time stiff enough to ensure adequate grip on the snow surface.
  • the structure of the ski must furthermore be able to absorb the vibrations imparted thereto while skiing, in order to effectively control and handle the ski.
  • the aim of the present invention is therefore to eliminate the disadvantages described above in known types by providing a ski device which allows to achieve an optimum damping of the vibrations imparted to the ski and allows the skier to customise the flexibility of a ski according to his own physical requirements or to the characteristics of the snow surface.
  • an important object is to provide a structurally simple device as well as reliable and safe in use.
  • Another object is to provide a device which can be applied to known skis as well.
  • Not least object is to provide a device which associates with the preceding characteristics those of having modest manufacturing costs and of being applicable to skis in a rapid and simple manner.
  • a ski device with which a tip element and a heel element are associated, characterized in that it comprises at least one covering element associated with a ski, said at least one covering element being arranged between a ski binding member and an end of said ski, said covering elements being mutually interconnected by flexibility controlling and vibration damping means.
  • the reference numeral 1 indicates a single ski with which a tip element 2 and a heel element (not illustrated in the figure for the sake of simplicity) of a ski binding, are associated; a boot 3 is associable with said ski binding.
  • the device according to the invention comprises, at the interspace between the tip 4 and the tip element 2, or in the interspace between the rear end of the ski and the heel element, a first, second and third covering elements, respectively indicated by the numerals 5, 6 and 7.
  • Said covering elements may be resilient and thus be advantageously made of plastics.
  • the first covering element 5 is adjacent to the tip element 2 and has a box-like configuration, and may optionally embrace the tip element 2, at least partially.
  • First and second transverse recesses or seats, indicated by the numerals 8 and 9, are formed on the first element 5, for arranging a first screw 10 and a second screw 11 for fastening to the ski 1.
  • the third covering element 7 also has a box-like configuration, and third and fourth transverse seats, indicated by the numerals 12 and 13, are defined thereon for arranging a third screw 14 and a fourth screw 15 for fastening to the ski 1.
  • the second covering element 6 is arranged in the interspace comprised between the first and third covering elements, and its ends are advantageously inserted with a tight fit within the corresponding ends of the first covering element 5 and of the third covering element 7.
  • the second covering element 6 has means for controlling the flexibility and for damping the vibrations of the ski 1; said means are arranged at an adapted fifth seat 16 which is defined axially and internally with respect to said second covering element 6.
  • a pawl 17 is arranged centrally inside said fifth seat 16 and has a cylindrical configuration; its lateral surface is advantageously knurled and can be accessed outside said second covering element 6, which is internally provided with complementarily threaded regions.
  • said L-shaped ends of the first and second bars are partially arranged within the adjacent box-like ends of the first covering element 5 and of the third covering element 7, and resilient elements, such as a first spring and a second spring, or resilient blocks made of plastics or rubber material, indicated respectively by the numerals 20 and 21, are interposed between said ends.
  • the use of the device is as follows: once the first, second and third covering elements have been associated with the ski, for example so that the first covering element totally or partially covers the tip element or the heel element of the ski binding, the skier can vary the degree of flexibility and/or of vibration damping of the ski by acting on the pawl 17 so as to vary the position of the first and second bars within the second covering element 6.
  • figures 4, 5, 6 and 7 illustrate a second embodiment, in which a first covering element 105, a second covering element 106 and a third covering element 107 are again provided.
  • Tabs 122a and 122b protrude at the ends of the first covering element and of the second covering element which are respectively adjacent to the second covering element and to the third covering element, and the adjacent ends of the second and third covering elements are slidably associated on said tabs.
  • a pair of pins 124a and 124b protrude proximate to the front perimetric edge 123 of the covering elements and can be slidably arranged at adapted pairs of slots 125a and 125b defined laterally to the adjacent ends of the second and third covering elements.
  • Means for controlling the flexibility and/or the vibration damping of the ski are constituted by resilient elements 120, such as springs or rubber pads, which may even have different degrees of compressibility.
  • Said resilient elements 120 can be arranged at adapted sixth seats 126a and 126b which are defined axially to the first and second covering elements and to the second and third covering elements respectively at their mutually adjacent ends.
  • Figures 8, 9 and 10 illustrate a further embodiment of the device, in which only the interactions between the first covering element 205 and the second covering element 206 have been illustrated for simplicity.
  • the first covering element 205 again has, proximate to its end which is adjacent to the corresponding end of the second covering element 206, a tab 222a from which a pair of pins 224a protrude laterally and can slide in adapted slots 225a.
  • a slider 227 which can be operated by the skier, is slidably associated at the interspace between the adjacent ends of the first and second covering elements and therefore at the tab 222a, and has an essentially T-shaped configuration; its wings 228a and 228b slide in adapted and counter-shaped guides defined on said ends of said first and second covering elements.
  • the first, second and third covering elements may furthermore have, at the ends which interact with the ski 201, wings 229a and 229b which are slidably associable at adapted U-shaped profiled elements 230 which can be coupled directly to the ski 201.
  • Figures 11 and 12 illustrate a further embodiment, in which the means for controlling flexibility and for damping vibrations are constituted by one or more pistons 331 which have a body 332 from which a pair of stems 333a and 333b extend; said stems can be advantageously articulated transversely to the first covering element 305 and to the third covering element 307.
  • the axes of said pistons 331 may be parallel with respect to the longitudinal axis of the ski or may have a divergent or converging direction with respect to the tip of the ski.
  • Figure 13 illustrates still a further embodiment, wherein the flexibility controlling and damping vibrations means are constituted by a single resilient element 420 which is shaped complementarily to the first covering element 405, to the second covering element 406 and to the third covering element 407.
  • Said covering elements may also be constituted by a single element provided with adapted transverse recesses suitable for allowing differentiated articulation at said regions.
  • a ski device has thus been provided which allows to rapidly and easily change the characteristics of the ski itself, passing from a resilient ski to a stiff one, limiting and controlling the vibrations thereof while skiing.
  • the executable adjustments can be based on the different types of snow surface, on the different types of track and of course on the skill of the skier.
  • the covering elements can constitute an aesthetically advantageous element when they are applied to the ski, by partially or totally concealing the elements which constitute the ski fastening.
