Definitions

  • the present invention relates to a ski, in particular an alpine ski. It relates more particularly to an improvement in this type of skiing.
  • ski we already know different types of ski and there are many variations. These consist of an elongated beam whose front end is curved upwards to form a spatula, the rear end also being more slightly to form the heel.
  • the structure generally comprises peripheral protection elements, internal resistance elements to resist the flexural and torsional stresses, and a core. These elements are assembled by gluing or by injection, the assembly generally being carried out hot in a mold having the final shape of the ski, with a front part strongly raised in a tip, a rear part slightly raised in the heel, a central arched part. .
  • skis intended for strong skiers are generally much stiffer and respond much more quickly to flexion stresses, particularly at high speed and on bumpy courses and difficult snow.
  • their excessive stiffness is harmful for easy driving and good mobility of the ski.
  • Document DE 39 33 717 presents a ski, the binding elements of which are fixed to a covering part; itself secured to deformable elastic bodies allowing continuous deformation and without providing additional stiffness to the ski, in particular, when passing over heavily uneven terrain.
  • the object of the present invention aims, on the contrary, to increase the stiffness of the ski from a certain determined flexion value.
  • the ski of the present invention aims to provide an improvement to the aforementioned drawbacks.
  • the improvements brought about by the invention give the ski a satisfactory behavior under all conditions of use, even the most extreme.
  • the ski according to the invention comprises a first lower sub-assembly or base, the front end of which is raised to form the tip; and a second upper sub-assembly or stiffener, characterized in that the upper sub-assembly is formed by two parts of beam or section with separate evolving section, each linked to the first lower sub-assembly either by a flexible connection extending partially or totally between the upper sub-assembly and the base, either by a rigid connection extending partially between the upper sub-assembly and the base, and in that the two parts are aligned along the longitudinal axis of the ski , and are spaced from one another by a clearance when the ski is at rest and the parts cooperate with each other when the ski is stressed in bending, from a determined bending value, so as to increase the stiffness ski.
  • the stiffener in two parts has a length of between 50 and 80% less than the length of the surface of the base in contact with the snow.
  • the front and rear parts are partially linked to the base by rigid connections.
  • the front and rear parts are totally linked to the base, each by a flexible connection.
  • the two parts of the stiffener are connected by a damping device.
  • the free space between the two parts of the stiffener can be completely or partially occupied by an elastic system, notably of spring.
  • the ski of the invention as shown in FIG. 1 according to a first embodiment, comprises a lower sub-assembly or base (1) and an upper sub-assembly or stiffener (2).
  • the stiffener consists of a first front part (20) and a second rear part (21).
  • the two front (20) and rear (21) parts extend longitudinally and are separated from each other. They each have an upper surface (201, 210) spaced apart by a small distance (d) so as to provide a clearance (22) between each part (20, 21).
  • Each part (20, 21) is linked to the base by connecting means (3).
  • the parts (20, 21) of the stiffener are aligned along the median longitudinal axis (I, I ') of the ski.
  • the two parts are two symmetrically identical beams (symmetry with respect to the median vertical axis (II-II ')). But of course, this characteristic is not essential to the invention.
  • the base (1) is the element in contact with the snow and is in the form of an elongated beam (10) having its own distribution of thickness, of width and therefore its own stiffness.
  • This elongated beam can have a stiffness less than or equal to that of a conventional ski.
  • the base (1) comprises a slightly arched central part (113), having a lower sliding surface (114) and an upper surface (115).
  • the central part (113) occupies most of the length of the base and is extended on the one hand at the front by an anterior part (116) raised to form the spatula (117) and on the other hand, by a rear part (118) slightly raised to form the heel of the ski.
  • the rear part (118) being relatively short and of low lift, and the front part (116) is longer and much more arched, as is known per se and shown in the figures.
  • the upper face (115) of the central part (113) of the base (1) is covered with a stiffener (2) in two parts.
  • This element is intended to complete the distribution of the stiffnesses of the base (1) so as to obtain the desired overall distribution.
  • the application of a bending force from the top to the bottom leads to a reduction in the distance (d) or the clearance (22) created between the two surfaces (201, 210) of the parts of the stiffener creating a support of the two surfaces (202, 212) of the two parts of the stiffener and thus increasing the stiffness of the ski.
  • the curve in FIG. 4 shows the shape of the change in the stiffness of the ski as a function of the increase in the bending force (F) applied to the ski.
  • the portion A of the curve corresponds to the application of force values below the minimum input value as a function of the stiffener.
  • the stiffness of the ski is then that of the base.
  • the portion B corresponds to the operating range of the stiffener, resulting in an increase in the slope of the curve due to the stiffness input from the stiffener.
  • FIG. 5 and FIG. 6 show an example of the structure of the ski of the invention.
  • the structure of the base (1) can be of the sandwich type or of the box type or of any other type.
  • a preferred structure is shown comprising a rigid upper reinforcement (101) in the form of a shell with a "U" section forming a top wall (102) and two side walls (103 and 104) covering a core (105 ), the assembly being closed at its lower part by a lower element (106) comprising the metal edges (107, 108), a sliding layer (109) generally made of polyethylene as well as lower reinforcement elements (110, 111) .
  • An upper surface layer (112) covers the upper reinforcement to form the decor of the base.
  • the reinforcing layers (101, 110, 111) can be of all types such as layers of composite materials such as fiberglass, carbon fiber with epoxy or polyester resin, or even a metal alloy.
  • the core (105) can be filled or unloaded foam, wood or aluminum honeycomb.
  • the surface layer providing the decoration may be made of a thermoplastic material such as polyamide. It can be monolayer or made up of several layers.
  • each part (20, 21) of the stiffener is of the box type and is formed of a core (23) disposed between an upper reinforcement ( 24) and a lower reinforcement (25).
  • the structure could also be of the sandwich type, that is to say be made up of a stack of different elements such as reinforcements and cores.
  • the stiffener (2) can also be constituted by a simple profit in the form of "Omega" for example.
  • provision can be made to make the stiffener made of composite material by the technique of TRE (Thermoplastic Reinforced Stampable) or SMC (Sheet Molding Compound) for example.
  • the upper reinforcement (24) is covered with another additional reinforcement layer (240) in the shape of an inverted "U” and forming an upper wall and two side walls (241, 242).
  • a surface layer (26) covers the top and the side faces of the stiffener (2) to form the finish and the decoration thereof.
  • the reinforcing layers of the stiffener can be of all types such as layers of composite materials such as fiberglass, carbon fiber, with epoxy or polyester resin or still metallic or fibro-metallic reinforcements.
  • the core (23) can be filled or unloaded foam, wood or aluminum honeycomb.
  • the surface layer providing the decoration can be made of polyamide for example, be monolayer or multilayer.
  • connection means (3) such that the connection between the two elements is flexible and / or partially rigid.
  • FIG. 1 to 6 shows an example in which the connections (3) between the base assemblies (1) and parts (20, 21) of the stiffener (2) are completely flexible.
  • the connecting means (3) are produced by a flexible interface (30) arranged between the base (1) and the entire length of each part (20, 21) of the stiffener (2).
  • the interface under each part (20, 21) has a width l3 equal to that of each part and a length L3 equal to the length of each part of the stiffener.
  • the interface (30) is produced by a layer of a flexible material of the elastic type, and in particular of the viscoelastic type, of thickness from 0.1 to 5 mm, which is glued or welded on the one hand, to the surface upper (115) of the base (1) and secondly, under the lower surface of the stiffener.
  • the material used can be elastic with a hardness of 10 to 85 shores A or a viscoelastic material with a modulus of elasticity of 15 to 160 megapascals, a hardness of 50 to 95 shores A and a damping value of 0.13 to 0.72.
  • these data are only exemplary embodiments for a temperature of 20 degrees and a frequency of 15 hertz.
  • the interface (30) is fixed to the base (1) and the stiffener (2) is produced either by a thermosetting resin of the polyester, vinylester or polyurethane epoxy type or a thermoplastic film such as a polyamide, or any other way.
  • connection between each part (20, 21) is partial and produced at the front and rear end of the stiffener.
  • the front part (20) of the stiffener is linked by its front end (203) over a length l1.
  • the rear part (21) is linked by its rear end (213) over a length l2.
  • the connections (3) in this case are flexible and produced by two flexible interfaces.
  • connection (3) between the base (1) and each part of the stiffener (2) is partially rigid; that is to say that the connection, when it is rigid, does not extend under the entire surface of the stiffener (2) to allow in particular a bringing together of the parts of the stiffener between them.
  • the rigid connection (3) can be obtained by any means such as bonding, by mechanical connection such as screws or rivets or even by welding, in particular by ultrasound or by vibration.
  • connection (3) between the base (1) and its stiffener (2) can be mixed, that is to say partly flexible and partly rigid.
  • FIGS 8 and 8a show an interesting variant of the invention in which a damping device (4) connects the two parts (20, 21) of the stiffener.
  • the space or clearance (22) between the two parts (20, 21) when the ski is at rest is occupied by a pad of viscoelastic material having damping properties.
  • the pad compresses as the ski is stressed in flexion. It is preferably held in place by gluing against the surfaces (202, 212) of the front and rear parts of the stiffener.
  • FIG. 9 shows the variation curve of the stiffness as a function of the force applied in bending.
  • the first portion A of the curve illustrates the compression range of the pad (4).
  • the stiffness no longer varies linearly as a function of the flexion applied but gradually.
  • Section B illustrates the incompressibility range of the tampon (4). In this case, the stiffness varies linearly depending on the stresses applied.
  • damping device one can also provide any type of device such as hydraulic or gas compression, for example.
  • FIGS. 10 to 11 show a variant of FIGS. 8 and 8a in which the damping is done by shearing of a pad of viscoelastic material connecting a first portion (205) of upper surface of one of the parts (20) to a second portion (215) of lower surface of the other part (21).
  • the clearances (206, 216) allow complementary fitting of the ends (204, 214) of the parts of the stiffener when the ski is stressed in bending as shown in FIGS. 12 and 12a.
  • the damping effect can be limited to avoid a possible tearing of the pad (4) by the contact of the surfaces (202, 212) of the ends (205, 215) of the parts (20, 21) of the stiffener.
  • Figures 13 to 15 illustrate another variant of the invention where the space or clearance (22) created between the two parts (20, 21) is occupied by an energizing system (5) offering an elastic restoring force to the stresses of bending of the ski.
  • the system can be an elastic system, in particular a spring.
  • the bending forces of the ski result in a bringing together of the two parts (20, 21) of the stiffener between them, which compress the spring (5) and create a restoring force proportional to the bending force exerted as shown in the first portion A of the curve in FIG. 15.
  • the second portion B shows the effect provided by the stiffener when the end of the stroke of the spring (5) is reached (FIG. 14a).
  • the energizing system (5) only partially occupies the clearance (22) separating the two parts of the stiffener.
  • the system (5) is integral with the end (201) of one of the parts.

  • the dimensions of the housing both horizontal "l4" and vertical "h4" are greater than the horizontal dimensions "l3" and vertical "h3" of the parts of the stiffener to form a space necessary for the freedom of the latter, as the shows figure 19.
  • the stiffener does not directly receive the stresses of the skier. Also, the support or the stirrup (6) is supported only on the base (1).
  • connection between the support and the base is rigid or flexible and obtained for example by gluing, welding or any other means, such as mechanical.
