Definitions

  • the present invention relates to a ski and more particularly to an improvement of its front end.
  • Alpine, cross-country or cross-country skiing ends at the front with a spatula which is curved upwards so as to facilitate sliding of the ski over snow.
  • This tip which generally ends in a point, is an integral part of the rest of the ski and therefore it can cause serious injury to another skier, in the event of a frontal impact with the latter.
  • a rigid spatula forming a single piece with the rest of the ski, can destabilize the skier or even cause his fall if it comes to strike a stake when the skier performs a descent marked by such stakes (slalom test for example ).
  • the frontal shocks received by the tip are transmitted to the entire ski and this may result in degradation of the latter.
  • the present invention aims to remedy these various drawbacks.
  • this ski comprising, at the front, a spatula, is characterized in that its spatula is constituted by a part independent of the ski itself, mounted movable relative to the front of the ski, and by at least one element. elastic interposed between the independent moving part and the front of the ski itself.
  • Figure 1 is a vertical and longitudinal sectional view of the front part of a ski comprising an independent spatula which can slide longitudinally.
  • FIG. 2 is a substantially horizontal sectional view taken along line II-II of FIG. 1.
  • Figure 3 is a cross-sectional view taken along line III-III of Figure 1.
  • FIG. 4 is a plan view of the front part of the ski shown in FIG. 1.
  • Figures 5 and 6 are views in vertical and longitudinal section of alternative embodiments of the front part of the ski.
  • Figure 7 is a plan view of another alternative embodiment of the front part of the ski.
  • FIG. 8 is a view in vertical and longitudinal section of the front part of the ski shown in FIG. 7.
  • Figure 9 is a vertical and longitudinal sectional view of another alternative embodiment of the front part of the ski.
  • FIG. 10 is a substantially horizontal sectional view taken along the line X-X in FIG. 9.
  • FIG. 11 is a plan view of the front part of the ski shown in FIG. 9.
  • Figure 12 is a vertical and longitudinal sectional view of another alternative embodiment of the front part of a ski.
  • FIG. 13 is a substantially horizontal sectional view taken along the line XIII-XIII of FIG. 12.
  • Figure 14 is a vertical and longitudinal sectional view of another alternative embodiment of the front part of a ski.
  • Figure 15 is a sectional view taken along the line XV-XV of figure 14.
  • Figure 16 is a vertical and longitudinal sectional view of another alternative embodiment of the front part of a ski.
  • FIG. 17 is a plan view of the front part of the ski shown in FIG. 16.
  • Figures 18 and 19 are views in substantially horizontal section of alternative embodiments of the front part of the ski.
  • Figure 20 is a vertical and longitudinal sectional view of an alternative embodiment of the front part of a spatula ski that can pivot about a transverse axis.
  • FIG. 21 is a substantially horizontal sectional view taken along the line XXI-XXI of FIG. 20.
  • Figures 22 and 23 are plan views of the front part of skis having an independent asymmetrical tip.
  • the tip comprises an independent tip 2 which is mounted to slide longitudinally on the front of the ski 1.
  • the tip 2 is hollowed out by a blind recess 3 extending in the plane of the end piece 2, closed at the front by a transverse bottom 3a and which opens into the rear end face 2a of the end piece 2.
  • a central tongue 4 which is an integral part of the ski 1 and which extends forward from the front face 1a of the ski 1 proper.
  • This tab 4 has a transverse width or dimension less than the width of the ski and its thickness is substantially equal to the vertical dimension of the recess 3 so that the end piece 2 is fitted tightly onto the tongue 4, while being able to slide on this tongue.
  • the front front face 4a of the tongue is located at a distance behind the bottom 3a of the recess 3 so as to leave a longitudinal play a between them allowing a slight sliding of the end piece 2 towards the rear.
  • the ski tip also includes an elastic element 5, forming a shock absorber, which is interposed between the rear front face 2a of the end piece 2 and the front front face 1a of the ski 1.
  • the shock absorbing element 5 can be formed , as shown in the embodiment illustrated in Figures 1 to 4, by a ring of an elastic material, for example of the rubber type, which is integral with the rear end face 2a of the nozzle 2, surrounding the opening of the recess 3 into which the tongue 4 enters.
  • the elastic ring 5 can be fixed to the rear front face 2a of the end piece 2 by any appropriate means, for example by molding or by bi-material injection.
  • the end piece 2 is itself made of a relatively hard material making it possible to absorb shocks and wear.
  • the tip 2 of the tip can, in the event of a frontal impact, slide backwards with respect to the ski 1, compressing the elastic element 5 forming a shock absorber. shock.
  • This sliding movement is made possible by the longitudinal play a existing between the front end face 4a of the tongue central 4 and the front transverse bottom 3a of the recess 3.
  • the tip 2 of the spatula is retained forwards, on the central tongue 4, by any appropriate means.
  • this retention can be ensured by providing, in the two lateral faces of the tongue 4, two opposite notches 6, formed at the place where the tongue 4 is connected to the front end face 1a of the ski 1.
  • the ring 5 forming shock absorber, secured to the tip 2 of the spatula is engaged elastically in the two opposite notches 6, which ensures, because the ring 5 is secured to the tip 2, the maintenance in place of this tip on the tongue 4, by "snap", in the extension of the front of the ski 1.
  • the parts of the elastic ring which are engaged in the two notches 6, have convex surfaces closely matching the concave profiles of the two notches 6.
  • similar notches can also be provided in the upper and lower faces of the tongue 4 so that the elastic ring 5 is anchored on the four faces of the tongue 4.
  • the recess 3 and the tongue 4 may each have a rectangular shape or, which is preferable, an isosceles trapezoid shape converging towards the front, as can best be seen in FIGS. 2 and 4.
  • the part of the trapezoidal tongue 4 which is engaged in the recess 3, has a longitudinal dimension which is less than the depth or longitudinal dimension of the trapezoidal recess 3.
  • the inclined lateral faces 4b of the trapezoidal tongue 4 have a angle of inclination between them which is greater than the angle of inclination of the two inclined lateral faces 3b of the trapezoidal recess 3.
  • the longitudinal play a and the lateral play b thus allow the end piece 2 to undergo, in the event of an impact, not only a pure longitudinal movement towards the rear, in the event of a purely frontal impact, but also a complex movement of translation towards the rear and lateral pivoting, in the event of an oblique impact, this lateral pivoting being made possible as a result of the provision for lateral clearance b .
  • the overall thickness of the elastic ring 5 forming a shock absorber which is equal to that of the end piece 2, in the region of its posterior front face 2a, is slightly greater than the thickness of the front of the ski 1, so that the upper and lower faces of the elastic ring 5 are slightly projecting from the upper and lower faces of the ski 1.
  • the elastic ring 5 is extended towards the rear by an external peripheral lip 5a which covers, over a short distance, the upper and lower faces of the ski 1, thus ensuring continuity between the ski 1 and the elastic ring 5.
  • a layer of elastic material 5b is also interposed between the upper and lower faces of the central tongue 4 and the upper and lower faces of the recess 3, so as to also create shock absorption. in the vertical direction.
  • the central tongue 4 and the recess 3 are eliminated and the elastic element 5 shock absorber is then constituted by a piece of solid elastic material, extending transversely and ensuring the junction between the rear end face 2a full of the mouthpiece 2 of the tip and the front face 1a of the ski 1.
  • the elastic member 5 is fixed by any suitable means, for example by gluing, to the two end faces 1a and 2a.
  • the elastic element forming a shock absorber consists of a mass of elastic material 7 which fills the space defined between the faces 3a, 3b of the recess 3 and 4a, 4b of the tongue 4.
  • the retention of the end piece 2 towards the front is obtained by bosses 8 which are formed in the connection zone of the lateral faces 3b of the recess 3 and of the posterior front face 2a of the nozzle 2 and which project inwards. These bosses 8 are engaged respectively in the two notches 6 provided in the lateral faces of the central tongue 4.
  • the rear front face 2a of the end piece 2 defines, with the front front face 1a of the ski 1, a empty space 9 which is surrounded by a peripheral sealing lip 11, extending towards the rear, forming an integral part of the end piece 2.
  • This lip 11 covers the four faces of the ski 1 over which it can slide.
  • a frontal and / or lateral impact is absorbed by the elastic deformation of the layer of shock absorbing material 7 which is then compressed between the end piece 2 and the central tongue 4.
  • the tip 2 is full and its front face 2a is extended rearward by a central tongue 4.
  • the front part of the ski 1 is hollowed out by a recess 3 receiving the tongue 4 secured to the end piece 2.
  • the nozzle 2 constituting the independent piece of the spatula is itself made entirely of elastic material. It is snapped onto the central tongue 4, by bosses 8 engaged in notches 6 formed in the lateral faces of the tongue 4, and it has, at the rear, a peripheral edge 13 of small thickness, which bears against the front front face 1a of the ski 1. This edge 13 acts as a shock absorbing element, because it can then be crushed somewhat to absorb the energy of the impact.
  • FIGS 16 and 17 illustrate an alternative embodiment in which the central tongue 4 carries an upper plate 14, of elastic material, which is housed in a recess 15 formed in the upper part of the nozzle 2 constituting the spatula.
  • the plate 14 is fixed, at its lower part, to the tongue 4 by any appropriate means, for example by lower pins passing through holes drilled in the tongue 4 and terminated by deformed heads 16 in the form of rivet heads.
  • the plate 14 rests, by its tapered front part, on a ramp 17 inclined from bottom to top towards the front, which is formed on the upper face of the tip 2.
  • this end piece 2 causes, by moving back slightly with respect to the tongue 4, the lifting of the tapered front part of the plate 14, which then takes a curved shape towards the top, as indicated in dashes in FIG. 16.
  • This deformation of the plate 14 makes it possible to absorb the energy of the impact and this plate then returns to its initial shape, due to its elasticity.
  • Figures 18 and 19 illustrate alternative embodiments in which the elastic element forming shock absorber is constituted by a mechanical spring.
  • the end piece 2 is pushed forward by a spring leaf 18, forming a bending spring.
  • This leaf spring 18 is arched so as to have a convex shape towards the front, to extend transversely and to bear, by its two ends, on the front front face 1a of the ski 1 and, by its convex median part. towards the front, against the posterior front face 2a of the end piece 2. Consequently if the end piece 2 of the spatula moves back under the effect of a frontal impact, it causes a crushing of the spring leaf 18 which collects thus the energy of the shock.
  • the end piece 2 can be retained forwards by any suitable means, for example by means of a vertical finger 19 secured to the tongue 4 and engaged in a longitudinal slot 21 in the end piece 2.
  • the elastic element forming shock absorber can be constituted by at least one longitudinal compression spring.
  • the tip 2 of the spatula is thus pushed forward by two compression springs 22 extending longitudinally and engaged, at their ends, in housings dug opposite the one from the other respectively in the front front face 1a of the ski 1 and in the rear front face 2a of the tip 2 of the tip.
  • Figures 20 and 21 illustrate an alternative embodiment in which the tip comprises an independent tip 23 which is articulated on the front of the ski 1, around a transverse axis 24.
  • the tip 23 of the tip is biased towards its normal position, in the extension of the front of the ski 1, by one or more springs such as torsion springs 25.
  • torsion springs 25 In this case the energy of a frontal impact is absorbed by pivoting the end piece 23 of the tip counterclockwise around the axis 24, the spring or springs 25 then playing the role of elastic shock absorbing element.
  • the springs 25 ensure the return of the tip 23 of the tip in its normal position, in the extension of the ski 1, after the impact.
  • FIG. 22 shows the front of a ski, the tip of which has a tip made of rigid material 26 of asymmetrical shape, in the case of a ski more particularly suited to the practice of slalom.
  • the endpiece 26 is connected to the front front face 1a of the ski 1 by means of an elastic element 27 which has, seen substantially in plan, a corner or circle sector shape.
  • the apex 27a of the wedge-shaped elastic element 27 is situated in the plane of the outer edge 1b of the ski 1 and to this apex 27a is connected the convex outer edge 26a of the end piece 26.
  • the elastic element 27 has, on the side opposite its summit 27a, an edge 27b which ensures continuity between the internal edge 1c of the ski 1 and the concave internal edge 26b of the endpiece 26.
  • the tip 26 of asymmetrical shape is made of elastic material and it is connected to the front front face 1a of the ski 1.
  • This tip 26 has, on the side of the internal edge 1c of the ski 1 , a concave edge 26b and on its convex outer edge is attached a curved element 28, made of hard impact-resistant material, which extends from the end of the end piece 26, to the point of connection between the front front wall the ski 1 and its external edge 1b.
