Description

  • The present invention relates to snowboarding.
  • A board is made up of a board having the general structure of a ski, that is to say comprising a tip, a skate area and a heel, the sole being delimited laterally on the underside of the board by two metal edges. As on a ski the dimension lines, that is to say the lateral curvature of the edges can vary, according to the characteristics which the surfing must include. When the edges are curved to provide a narrower board in the middle than at its ends, a board is said to have a profile in the shape of an "wasp waist". The larger the wasp size, the easier it is to initiate a turn. On the contrary, a smaller wasp size makes it more difficult to initiate turns, but favors the conduct of surfing on hard snow at high speed.
  • The document DE-A-2924023 describes a monoski comprising a lower part intended for guiding on snow, of width less than the upper part, which is used for mounting the bindings and which has curved edges in the direction of the longitudinal median axis in the skate area.
  • On a board, the user's two feet are fixed longitudinally offset relative to each other. If, originally, the feet were fixed parallel to each other and perpendicular to the axis of the surf, the two feet are now slightly turned forward, and diverging forward to respect the natural position of an individual's legs. If this position improves comfort and ability to evolve, it has the disadvantage, in the case of a wasp-sized surf fairly marked, that the center of gravity of the user passes, when taking edge forwards, in front of the most curved part of the dimension line, or when taking an edge backwards, behind the most curved part of the dimension line. It follows that the attachment of the edge considered on the snow is not done uniformly, the heel is not sufficiently loaded in the first case, while the tip is not sufficiently loaded in the second case. It is for this reason that most surfboards have only a slightly marked wasp profile.
  • Another difficulty encountered by beginners in the practice of surfing lies in the initiation of turns. Indeed, the edges being beyond the ends of the feet of the user, it is necessary to give an important impulse to strongly incline the surfing, in order to carry out an edge grip.
  • The present invention aims to remedy these drawbacks.
  • To this end, the surf it relates to, of the type comprising a wasp-shaped profile, that is to say the dimension lines of which are curved in the direction of the longitudinal median axis of the surf in the skate area of it, is characterized in that the fixings each form a non-zero angle with a line perpendicular to the longitudinal axis of the surf, and in that the two dimension lines are offset longitudinally one relative to the other and are positioned so that the most curved point of each dimension line is located on the axis of symmetry of the axes passing through the two fixings.
  • It follows from this structure that, whatever the front or rear support of the user on one or the other edge, its center of gravity passes through the point of maximum curvature thereof, which ensures a perfect balance in surfing, which is neither oversteer nor understeer.
  • Advantageously, the rear edge delimiting the heel is inclined relative to the perpendicular to the longitudinal axis of the ski, the longitudinal edge located on the side of the rear of the bindings being longer than the longitudinal edge located on the side of the front of the fixings, of a value equal to the offset of the dimension lines.
  • In addition to the functional characteristics resulting from this structure, it gives the surf a particular aesthetic quite pleasant.
  • In practice, the longitudinal offset between the two dimension lines is of the order of 5 cm.
  • According to another characteristic of the invention, this surf comprises two pairs of edges, namely the traditional outer edges, and two other edges, each parallel to one of the outer edges, arranged closer than the latter to the axis. longitudinal of the surf, under the feet of the user, the plane containing the interior edges being located below the plane containing the exterior edges.
  • The inner edges, arranged under the feet of the user, allow tilting and pressing on an edge easier than traditionally, ensuring a rapid turn initiation, facilitating the practice of surfing by beginners, without harming the ability to slip easily. In addition, on groomed snow, it is possible to bring the surf in a balanced position in which it rests on its two edges located on the same side, before gradually increasing the angulation and bringing surfing on the outer edge in curves taken at higher speed.
  • Advantageously, the distance between two edges located on the same side is of the order of 55 mm, while their vertical offset is around 7 to 8 mm in the skate area.
  • According to another characteristic of the invention, each sole zone situated between an outer edge and an inner edge is offset vertically with respect to the central part of the sole, and is inclined from the inside towards the outside and of the sole. towards the upper face of the surf.
  • In any case, the invention will be clearly understood with the aid of the following description with reference to the appended schematic drawing representing an embodiment of this surf:
    • Figure 1 is a top view:
    • Figures 2 and 3 are two views of the cross section of this surf, respectively, flat and cornering of large radius;
    • Figure 4 is a side view.
  • The surfboard shown in the drawing and designated by the general reference 2 comprises, in a known manner, a spatula 3, a skid zone 4 and a heel 5.
  • This surf has a wasp-shaped profile, that is to say has dimension lines 6 and 7 having a marked curvature in their central part.
  • As shown in the drawing, this surfboard is equipped, in a known manner, with two fixings for the two feet of the user, designated by the reference 8 for the front fixation, and 9 for the rear fixation. The two bindings 8 and 9 are offset longitudinally, and form an angle with the perpendicular to the longitudinal axis 10 of the surf, the axes respectively 12 and 13 of these two bindings 8 and 9 being slightly turned forward relative to the perpendicular to the longitudinal axis 10, and these two axes 12 and 13 forming between them an angle slightly open towards the front, that is to say on the side of the dimension line 6.
  • The two axes 12 and 13 of the two fasteners 8 and 9 are therefore symmetrical with respect to a line 14, itself inclined with respect to the perpendicular to the longitudinal axis 10 of the surf.
  • As is apparent from FIG. 1, and according to the essential characteristic of the invention, the two dimension lines 6 and 7 are offset longitudinally with respect to each other, so that the point of maximum curvature of each dimension line 6, 7 is located at the point of intersection of line 14 with the dimension line considered. In practice, this longitudinal offset of the two dimension lines is of the order of 5 cm. Given the differences in positioning of the two dimension lines, the rear edge 15 delimiting the heel is inclined from front to rear and from the end of the dimension line 6 towards the end of the dimension line 7 .
  • It follows from this characteristic that, when the user takes an edge grip at the level of the dimension line 6, his center of gravity passes through the point of maximum curvature of this dimension line, so that the surf is perfectly balanced. Similarly when the user takes an edge grip on the edge corresponding to the dimension line 7, his sense of gravity passes through the point of maximum curvature of this dimension line, so that the surf is perfectly balanced, having neither a survivor nor a subviror character.
  • In accordance with another characteristic of the invention, this surf comprises two pairs of edges, namely the traditional outer edges 16 and 17 corresponding to the dimension lines 6 and 7, and two inner edges 18 and 19, parallel respectively to the edges 16 and 17 located in a plane below the plane containing the edges 16 and 17, and located under the support area of the feet of the user.
  • As shown in the drawing, the sole has a central part 20 and two lateral parts 22 offset vertically upwards with respect to the central part with a value of 7 to 8 mm in the shoe area. As for the lateral offset between the two edges 16.18 and 17.19, it is of the order of 55 mm.
  • It follows from this structure that, given the location of the edges 18 and 19 under the feet of the user, it is easy to tilt the surf on one of these edges to initiate a turn, by finding a position of equilibrium stable in which the corresponding outer edge is also supported on the snow. It is also possible to exceed this stable equilibrium position on two edges so as to only press on the outer edge as with traditional surfing. This structure greatly facilitates the learning of surfing, and driving it on groomed snow, without adversely affecting the sideslip capabilities.
  • As is apparent from the above, the invention brings a great improvement to the existing technique, by providing a surf of simple design, remaining perfectly balanced during turns on one or the other edge, while allowing execution short radius turns, thanks to a wasp-shaped profile that can be very marked, and has a very pleasant aesthetic.
