Definitions

  • skis are commonly known today which utilize to a considerable extent filament materials combined with resins. Using these materials results in a considerable weight saving and moreover offers the possibility to influence the long'itudinal-, lateral-, and torsional stiffness characteristic along the total ski in such a mode to gain distinguished gliding qualities. Since today an extreme high torsional stiffness is preferred new designs of skis apply a box type construction form which delivers a completely closed torsional tube with maximum torsional stiffness. On account of these modern structural designs it.is possible to form the ski body hollow.
  • the purpose of the invention is to accomplish a new ski with an adjustable device which offers the possibility to combine the stability qualities of a long and a short ski and all interim sizes by choice without changing the external dimensions of the ski and only by utilizing the adjustable device.
  • This peculiarity is solved according to the invention with a ski of the above mentioned characteristic by at least one movable mass which can be displaced in longitudinal direction of the ski by means of the adjustable device and which changes the mass moment of inertia about the vertical axis of the ski.
  • the invention provides, that, outside or inside of the ski masses can be arranged in a fixed movable position.
  • the mass moment of inertia can be changed considerably by changing the position of the masses either by fixing or shifting them to different places in longitudinal direction of the ski. Therefore it is possible to incorporate in only one ski the mass moments of inertia of short and long skis with all interim moments and to gain stability and gliding qualities which have not been known up to now.
  • only one or more, but espe cially two masses can be fixed at distinct places of the ski in an initial position from which they can be transferred to another fixed position or they can be shifted for instance continuously by means of a cable device in longitudinal direction of the ski and can be locked with the same device at an attained position simultaneously.
  • FIG. 3 is the same ski form as above but with another position of the masses shown in FIG. 1 and FIG. 2;
  • FIG. 4 is a more detailed presentation of the adjustable device shown in a cross section view
  • FIG. 5 is a view from above of the adjustable device shown in FIG. 4;
  • FIG. 6 is a cross section view of the end of the ski
  • FIG. 7 is a cross section view from above of the end of the ski shown in FIG. 6.
  • FIGS. 1, 2 and 3 the schematical arrangement, in a view from the sideand two top views, illustrates a hollow ski 5 in a box type construction which contains two continuously movable masses 1.
  • the masses 1 can be moved towards the center or to the ends of the ski 5 by means of a cable 3 and two guide pulleys 4 in such a manner, that they can be locked at all interim positions between the extreme outer position illustrated in FIGS. 1 and 2 and the extreme inner position illustrated in FIG. 3.
  • the position of a conventional ski binding is 'indicated by the reference number 6.
  • FIGS. 4, 5, 6 and 7 presented in two side views in cross section and two views from above one of which is also presented in a cross section view.
  • the movable masses 1 consisting of a material of high specific gravity are presented in form of a plate which may consist out of one piece, or, on account of the bending of the ski during skiing, of elements which are combined together flexible.
  • the adjustable device 2 is schematically presented by a cable pulley 21 and control disc 22 which is positioned above the ski 5 near the center. The masses 1 can be moved inside the ski body 51 within certain limits by the cable 3 which is guided around the two guide pulleys 4 and which can be moved'by operating the adjustable device 2.
  • FIGS. 6 and 7 a mass 1 is visible in an extreme closed position to the guide pulley 4' in the end part of the ski.
  • the guide pulley 4 and the mass 1 are partly covered by the cable 3 in FIG. 6.
  • mass means means mounted on said body for selectively moving said mass means in a direction generally parallel to the longitudinal axis of said body, said mass means in one longitudinal position on said body defining one stability and gliding characteristic, said mass means in another longitudinal position on said body defining another stability and gliding characteristic.
  • said mass means comprises a pair of masses both mounted for longitudinal movement on said body toward and away from each other and the center of said body.
  • said means for moving saidmasses comprises cable means guided by pulley means and drive means for driving said cable means relative to said body, said masses being secured to a reach of said cable means and being movable by said cable means along said body when said cable means is driven by said drive means.
  • said moving means comprises cable means guided by pulley means and drive means for driving said cable means relative to said body, said mass means being secured to a reach of said cable means and being movable by said cable means along said body when said cable means is driven by said drive means.
