Definitions
- the invention relates to a device intended to modify the natural distribution of a ski on its sliding surface.
- the invention also relates to a ski equipped with such a device.
- This device comprises a vertically movable feeler, on which part of the shoe rests.
- the probe is connected to a return rocker which transforms the vertical stresses picked up by the probe into horizontal stresses which are transmitted to the ski via a transmission plate.
- the vertical stresses of the boot are transmitted to the ski in the form of a bending moment applied to at least one of the ends of the ski.
- This bending moment changes the natural pressure distribution of the ski on the snow.
- the problem posed by the invention is to achieve a simpler construction of a device intended to modify the natural distribution of pressure of a ski on its sliding surface.
- the problem is solved according to the invention by the use of a flexible blade whose curvature is modified locally.
- a feeler on which the shoe rests is supported on the blade, in its zone of variable curvature.
- the ends of the blade are designed to be secured to the ski.
- the variation in curvature caused by the pressing of the feeler on the blade modifies its overall length, which results in a bending stress exerted on at least one of the ends of the ski.
- Figure 1 is a side view of the interface device mounted on a ski portion, and equipped with two front and rear retaining elements.
- Figure 2 is a top view of the construction of Figure 1.
- Figure 3 shows a side view of an interface device according to another embodiment of the invention.
- FIG. 4 illustrates another alternative embodiment of the interface device.
- Figure 1 shows the middle part of a ski equipped with two retaining elements 62 and 63 similar to the previous elements.
- the rear retaining element 63 is mounted on a base 64 secured to the ski.
- the element 63 is integral with the ski at least for the vertical direction.
- the front retainer 62 has a base plate 65 hinged to a base 66 about a transverse axis 69 located in front of the retainer.
- a base plate 65 hinged to a base 66 about a transverse axis 69 located in front of the retainer.
- any other suitable means of articulation is suitable.
- the front retaining element 62 has a support plate 68 on which the front part of the sole rests.
- the support plate 68 can oscillate over a small amplitude in an approximately vertical direction.
- the upward movement of the base plate 65 is limited by lugs 70.
- the base plate 65 Approximately under the support plate 69, the base plate 65 has a shoe 72 which projects beneath the base plate.
- the base 66 has a bowl 72, the shape and dimensions of which are provided so that the shoe can penetrate inside the bowl.
- a flexible blade 75 is extended overall between the front and rear fixing elements.
- the blade 75 has an inextensible nature, on the other hand, advantageously, it is highly flexible.
- it is formed by a metallic ribbon. It can also be carried out using one or more cables.
- the blade is fixed to the base. Due to the thickness of the base, the front end of the blade is raised relative to the upper surface of the ski. The blade rests against the upper surface of the base to the edge of the bowl, then passes over the bowl 72. An area 75a of the blade is therefore deprived of support between the edges of the bowl. The shoe rests on this zone 75a of the blade. Due to its flexibility and the presence of the bowl, the blade 75 has in its area 75a a variable curvature.
- the blade is securely connected to the ski by any suitable means.
- the blade is sandwiched between the slide and the base 64.
- the tension of the blade is sufficient for it to support at rest the component of the weight of the skier which passes through the front support plate 69.
- the bending moments to which the bases subject the ski depend on the intensity of the tensile stresses, but also on the altitude with respect to the ski of each of the anchoring points of the blade on the bases.
- the bowl can be filled with a block 77 of foam or any other suitable material to prevent snow and dirt from hindering the flexing of the blade in the bowl.
- the block may have damping or visco-elastic qualities.
- the block 77 may have a certain hardness to resist the support of the shoe 72 and increase the intensity of the shoe stresses which is necessary to vary the curvature of the zone 75a of the blade.
- FIG. 3 illustrates an alternative embodiment.
- the ski is equipped with two retaining elements 82 and 83.
- the front element 82 is mounted integrally on a base 84 which is itself secured to the ski.
- the rear element 83 has a slide 85 mounted articulated with respect to a base plate 86 around a transverse axis 87.
- the slide has on the front a support plate 89 on which the shoe sole rests.
- a blade 90 is stretched between the front and rear bases.
- the ends of the blade are for example secured to each of the bases, or else, as shown in FIG. 3, the blade 90 can be secured at the rear to the underside of the slide 85.
- the blade On the rear, the blade is guided by a support flange 91 of the base which is raised relative to the rest of the base.
- the edge is located in front of the front end of the slide 85. Beyond this edge, that is to say under the slide 85, the blade is detached from the upper surface of the base, and it is held without support on an area 90a which, due to the flexibility of the blade has a variable curvature.
- the slide is in abutment against this zone 90a of the blade, and for example, it has on the front and on its lower face a support shoe 92.
- the bending moment can be modified by the altitude of the point where the tensile stress is transmitted to the base.
- the rear element it would be possible to reduce the intensity of the bending moment by securing the blade not to the slide, but directly to the base, or else by providing in the base a central opening to lower the end of the blade to the upper surface of the ski.
- FIG. 4 represents an alternative embodiment according to which the blade 95 is secured to the ski at its two ends 95a and 95b situated respectively in front of the front retaining element 102 and behind the rear retaining element 103.
- the ends are joined to the ski by any suitable means, for example screws.
- the blade is raised relative to the upper surface of the ski and it is extended.
- FIG. 4 shows the blade raised forward by a base 96 located under the front retaining element 102.
- the blade passes freely over the base, for example at a groove or a slot.
- the blade is raised by a base 97 located under the rear retaining element.
- the blade is extended in traction.
- one of the constructions described relative to FIG. 3 can be used, with a bowl 98 located in the base 96, and an articulated base plate 99 pressing the blade by a shoe 100 located directly above the bowl.
- the present invention is not limited to the various embodiments which have just been described. It is possible to find many variants or technical equivalents.
- the flexibility of the blade could vary along the blade. That is to say that the blade could have maximum flexibility in its area where it is deprived of support, and could be more rigid, or even completely rigid over other parts of its length.
