Definitions

  • the invention relates to a device aimed at modifying the natural pressure distribution of a ski such as in particular an alpine ski on its sliding surface.
  • the invention also relates to a ski brake which is intended to brake the movement of a ski, in particular an alpine ski, in the event of release of the boot which is retained on the ski.
  • the invention also relates to a ski equipped with the preceding device or brake.
  • the skis which are used for the practice of alpine skiing consist of relatively long boards, on which the skier's shoes are retained by front and rear fastening elements.
  • the boots and the fasteners are located approximately in the middle area of the ski, which is commonly called the skate.
  • the skis have in themselves, at rest, a natural camber, by which the skate is raised naturally relative to the front end of the ski, or tip, and the rear end of the ski, or heel.
  • the skis have flexibility, which is due to their internal structure. During skiing, the ski deforms elastically in response to the various stresses to which it is subjected on the part of the skier, but also on the part of the terrain on which it slides.
  • the main stress to which the ski is subjected is constituted by the weight of the skier, and by the reaction to which the sliding surface subjects the ski.
  • the ski is also stressed by the binding elements. It is in fact known that the fastening elements pinch the shoe in a longitudinal direction. The reaction to this pinching action is transmitted by the binding elements to the ski. This reaction, however, has a different nature depending on the method of assembling the rear binding element to the ski. Indeed, some rear binding elements are assembled directly to the ski, while others are assembled to the front binding element by an inextensible link, such as a metal blade which extends under the boot.
  • Skiing is also influenced by the position of the skier over his boots, depending on whether he carries his weight forward or backward.
  • the behavior of the ski on snow can be modified, in particular its ease of initiation when cornering, its quality of driving when cornering or in a straight line, by influencing the camber of the ski, or even by playing on the longitudinal distribution of the ski pressure on the snow.
  • this pressure distribution it is known that one can make the ski more or less pivoting or more or less guiding, that is to say that one can promote its ability to turn easily, and to have great driving stability.
  • the pressure distribution of the ski on the snow is determined mainly by the internal structure of the ski, and by the method of assembly of the binding elements to the ski, that is to say with or without connecting blade between the front and rear elements.
  • the pressure distribution can also be influenced by the thrust intensity given to the recoil springs.
  • European patent application No. 183 586 describes a blade of material elastic spring blade type attached above the ski, between the binding elements and the ski. This blade has, at its front and rear ends, sliders through which a portion of the forces to which the ski is subjected passes vertically.
  • This device however has the disadvantage of having modest performance for a large size. It is suitable for the case where both feet of the skier are in support for the same ski, to avoid that the entire weight of the skier is concentrated in the skate area. On the other hand, it is ill-suited in the case of a pair of traditional skis.
  • these devices are designed to be fitted with standard fixing and braking elements.
  • no special arrangements are made for the brake to take account of the presence of the element which has been added to the ski.
  • One of the aims of the invention is to provide a device which makes it possible to dynamically modify the pressure distribution of a ski on its sliding surface, that is to say which takes account of the position of the skier on his skis, and the vertical pushing force exerted by the skier on his skis.
  • Another object of the present invention is to provide a device which also gives the skier a suspension effect during gliding.
  • Another object of the invention is to propose a device which induces a prestress in the ski, this prestressing being able to be eliminated in particular in the absence of the boot, when the ski is stored.
  • Another object of the invention is to provide a ski brake whose elements are integrated into the pressure distribution device.
  • the device according to the invention is intended to equip a ski, such as in particular an alpine ski, the ski being equipped with at least one fastening element intended to retain a boot in its central zone of the skate, and at least one plate d support on which the shoe sole rests.
  • the ski brake according to the invention comprises at least one movable brake arm between a working position where the arm projects under the lower surface of the ski, and a rest position where the arm rises along the lateral edges of the ski, it includes actuation means for returning the arms from their working position to their rest position when the shoe is engaged in the retaining binding, and an energy means for resiliently returning the arms to the working position when the shoe is released.
  • the actuation means comprise a set of two levers oriented in the longitudinal direction of the ski above it, articulated together around a horizontal and transverse axis in the manner of a toggle unstable movable between an open position and a flattened position against the upper surface of the ski, that one of the levers carries the brake arms and that the two levers are, moreover, connected to the base of the ski by connecting means in which they generate a taring preload, when the shoe is engaged in the fastening elements and actuates the toggle joint in the flattened position.

  • the front and rear slats 82 and 91 also play a role of transmission from the front to the rear of the ski or vice versa of the stresses to which one end of the base 1 is subjected.
  • an upward bending stress to which the front end of the base is subjected generates in the front batten 82 a rearwardly oriented longitudinal thrust force, which is transmitted to the connecting member 81 and to the rocker 87 which, if it does not pivot, fully transmits this stress to the rear batten 91.
  • the pushing force generates a bending moment which tends the rear end of the base towards the snow.
  • a bending stress on the rear end of the base is transmitted forward.
  • the front and rear slats 81 and 91 also play a role in absorbing the vertical vibrations to which the front and rear ends of the base are subjected. Indeed, these slats preferably have elastic bending qualities in a vertical direction.
  • the base plates 84 and 93 of the front and rear fastening elements overlap the stiffening slats 82 and 91, they have a guiding function for these slats, and in particular they prevent their buckling under the effect of '' compression stress.
  • the base plates 84 and 93 are however integral with the base, hence a good transmission of forces between the shoe and the base.
  • a longitudinal stop could limit the rearward movement of the rocker 87, and return to the ski at this level the longitudinal rearward thrust forces induced by the rocker 87.
  • FIG. 15 illustrates an alternative embodiment according to which the elastic return to the open position of the toggle joint 41 is produced by a torsion spring. This spring replaces the push springs 55 and 56 previously described.
  • This figure represents the two levers 93 and 94 which constitute the toggle 41.
  • the levers are articulated around an axis 95 which is offset downward relative to the plane defined by the main part of the lever 94.
  • the axis 95 is carried by the lever 94, and its ends circulate in lateral openings that the lever 93 has in its rear part.
  • a torsion spring 96 visible in FIG. 16 is wound around the axis 96.
  • the spring has two symmetrical windings 102 and 103, a central loop 99, and two free ends 100 and 101.
  • the free ends 100 and 101 are supported on the lever 93, in the region of the vertical bearing surface 98, while the central loop 99 is supported on the front end 97 of the lever 94.
  • the spring 96 exerts on the levers 93 and 94 a moment which resiliently recalls the toggle to its open position.
  • a pallet 102 extends the lever 93 backwards and extends above the lever 94 in the flattened position of the toggle.
  • the lever 94 carries the brake arms 110 and 111 with their segments 110a, b, c, and 111a, b, c, similar to the segments 10a, b, c, 11a, b, c, previously described.
  • the upper segments 110c and 111c are shorter than the segments 10c and 11c previously described. Indeed, they no longer have the function of an axis of articulation between the levers 93 and 94.
  • the lever 94 which constitutes the brake housing has at its end 97 an opening 112, through which the mouth 99 of the spring 96 bears against the segments 110c and 111c, in the vicinity of the median longitudinal and vertical plane defined by the ski.
  • the thrust force to which the brake arms are thus subjected tends to elastically keep these brake arms apart.
  • connection means only comprise a front connection member 120.
  • the connecting member 120 comprises two levers 123 and 124 which are of the same type as the levers 43 and 44 previously described.
  • the two levers are articulated together around an axis 125.
  • the front end is connected to the front fixing element in the same way as what has been described with reference to FIGS. 3 and 4, that is to say tell the base plate 14 by a transverse axis 42.
  • the axis 125 is carried by the lever 124, and it circulates in a slot 126 of the lever 123.
  • Springs 127 push the axle 125 elastically towards the rear end of the slot 126.
  • springs could be replaced by a spring such as spring 96, or by any other elastic return device of the toggle joint in the open position.
  • the free rear end of the lever 124 is connected to a rocker 135 with two branches, around an axis 136 which is located in the central part of the rocker.
  • the rocker 135 is itself articulated around an axis 137 located in its upper part, and which is carried by the lateral wings of the rear base plate 14.
  • the rocker 135 has a rear leg 135b on which rests, in a vertical direction, the front part of the rear slide 127. This slide, along which the body of the rear fixing element 4 slides, is articulated, relative to the base plate 18, about the axis 20 located in its rear part.
  • the lever 123 is extended towards the rear, above the lever 124, by a pallet 138.
  • the shoe In the flattened position of the toggle joint, the shoe is supported on the pallet 138 which is itself supported on the front part of the slide 127.
  • the stresses induce at the base plate before a bending moment which is transmitted to the ski.
  • the reaction is transmitted to the ski at axis 137.
  • the pretension induced in the front connecting member is created by the contact of the lever 124 against the bearing surface 129, and by the return force of the springs 127.
