Definitions

  • the present invention relates to a ski comprising a longitudinal rib at its upper part.
  • Skis are already known, in particular cross-country skis, which have a longitudinal rib on their upper face.
  • This longitudinal rib generally has a trapezoidal cross section, in other words it is delimited by a horizontal upper face and two inclined lateral faces, and this rib with trapezoidal cross section connects to the lower part of the ski which has a rectangular cross section, of low height, whose short sides constitute the edges of the ski. Due to the reduced height of these edges, such a ski slides more easily on snow.
  • the upper longitudinal rib can be used in particular for the lateral guidance of the boot mounted on the cross-country ski, which is adapted for this purpose thanks to the provision, in its sole, a groove having in cross section a shape complementary to that of the rib of the ski.
  • Such cross-country skiing is known in particular from patent FR-A-2565114.
  • the present invention relates to improvements made to such a ski with the aim of improving its technical qualities, without notably increasing its weight.
  • this ski comprising a central zone in which the sole of a shoe is supported and which is situated between two longitudinal front and rear zones which extend the central support zone respectively towards the front and towards the rear, and which are connected to flat anterior and posterior end portions of the ski, and an upper longitudinal rib extending over the most large part of the length of the ski, up to its flat end portions, is characterized in that the transverse section of the rib is formed, in the central zone, by the superposition of at least two elementary sections each having the form of '' a quadrilateral and connected by a common side constituting the lower side of the upper elementary section and the upper side of the lower elementary section whose lower side is horizontal, the lateral sides of the lower elementary section converging upwards and being more inclined, with respect to a vertical and longitudinal plane, than those of the upper elementary section, and in that in the anterior and posterior zones the transverse section of the rib has the shape of a single quadrilateral.
  • FIG. 1 a cross-country ski 1 which has a cross section with an evolving profile in the longitudinal direction and which has, at its upper part, over most of its length, a longitudinal rib.
  • the cross section of this rib, located above the edges of the ski, is made up, on certain parts of the length of the ski, by a single quadrilateral, in this case an isosceles trapezoid and, on another part of the length, by two superimposed quadrilaterals, in this case two isosceles trapezoids.
  • the cross-country ski 1 can be subdivided into three longitudinal zones where the longitudinal rib is formed, namely a central zone A which bears a cross-country ski chase (not shown) which is connected to the ski at its front end and whose the sole is provided with a longitudinal groove, and two front longitudinal zones B and rear C which extend the central support zone A respectively towards the front and towards the rear, and which are connected to anterior and posterior end portions flat, that is to say devoid of the longitudinal rib.
  • a central zone A which bears a cross-country ski chase (not shown) which is connected to the ski at its front end and whose the sole is provided with a longitudinal groove
  • two front longitudinal zones B and rear C which extend the central support zone A respectively towards the front and towards the rear, and which are connected to anterior and posterior end portions flat, that is to say devoid of the longitudinal rib.
  • the cross section of the rib of the cross-country ski 1 has the shape of a single isosceles trapezoid, while in the central longitudinal zone A its cross section consists of the superposition of two elementary sections, each has the shape of an isosceles trapezoid.
  • FIG. 1 are represented various profiles of the cross section of the cross-country ski 1 along the length.
  • At its extreme front cross-sectional part of the ski 1 1 has a flattened rectangular shape delimited laterally by the two vertical sides of the ski and 9.10 that is found all along the ski.
  • the cross section of the rib considered to be limited to the part situated above the lower rectangular part delimited by the edges 9, 10 and which is absent in the anterior extreme part, has, in the anterior longitudinal zone B, the shape of a single isosceles trapezoid, of height going backwards, as it is represented by the two profiles 1b of small height and 1c of greater height than the previous one.
  • a cross section of the rib 1 passes to the unique shape of an isosceles trapezium with the two superimposed isosceles trapezoids, as shown by profiles 1d and 1 e. Then the cross section of the rib again takes the form of a single isosceles trapezoid in the posterior section C, as illustrated by the profiles 1f, 1g, up to the extreme posterior part of the ski where the rib is absent and the cross section of the ski has a flattened rectangular shape similar to that of the anterior end portion.
  • the cross section of the rib of the cross-country ski 1 comprises an upper elementary section 2, defining a longitudinal guide rib proper, and a lower elementary section or base 3, these two elementary sections each having, in this case, the shape of an isosceles trapezoid.
  • the upper guide rib 2 has a horizontal upper face or edge 4 which is extended downwards by two inclined lateral faces 5,6.
  • the three faces 4,5,6 define the upper rib 2 which contributes to the lateral guidance and to the centering of the boot on the ski, as a result of the engagement of this guide rib 2 in the longitudinal groove of the sole of the boot, during the practice of cross-country skiing.
  • the inclination of the lateral faces 5, 6 of the upper guide rib 2, with respect to the vertical and longitudinal plane of symmetry P of the ski varies from the front to the rear of the central support zone A.
  • the angle a formed by the inclined lateral faces 5, 6 with the vertical plane P varies from 0 to 10 degrees and is preferably close to 5 degrees, while in the rear part of the central support zone A, where the heel of the shoe applies, this angle is more important and it can vary from 20 to 40 degrees.
  • the lower trapezoidal elementary section or base 3 comprises two inclined lateral faces 7,8 extending downwards the inclined lateral faces 5,6 and symmetrical with respect to the vertical plane P.
  • the inclined lateral faces 7,8 of the base 3 are more inclined, with respect to the vertical and longitudinal plane P, than the upper inclined faces 5,6, the angle of inclination b of these faces 7,8 with respect to the plane P can vary from 30 to 60 degrees.
  • the two lower inclined lateral faces 7,8 of the base 3 are connected to the vertical edges 9,10, of low height, of the ski.
  • FIGS 2 to 20 illustrate, by way of non-limiting examples, various embodiments of the cross-country ski according to the invention.
  • cross-country skiing is achieved by assembling, by gluing, several profiles preferably made of a composite material of the glass-epoxy resin type.
  • the cross-country ski is obtained by the assembly of two profiles, namely an external profile 11 or "shell", whose evolving cross section defines the profile of the ski over its whole length, as has been explained with reference to FIG. 1, and an internal profile 12 or "core” which retains the same shape of cross section over the entire length of the ski but whose height is variable.
  • the ski also comprises a lower horizontal reinforcement element 13 which is glued under the core 12 and under this reinforcement element 13 is in turn glued the sole 14 of the ski itself.

  • the advantage of such a distribution is that it makes it possible to obtain effective support for the upper guide rib, formed by the faces 4,5,6, to reinforce the "internal element or core 12" when it is pushed in. to reinforce the ski edges and to fulfill the shearing functions of a ski core while providing a hollow and light structure, having an excellent resistance / weight ratio.
