Definitions

  • the invention relates to the field of snow sliding sports, more precisely that of alpine skiing. It aims to improve the structure of such skis intended to receive a platform for raising and unlocking the ski.
  • the sliding material is mainly consisting of a sliding board proper on which is A mounting area for the binding is defined in a standardized manner. This area of mounting the mounting receives a safety mounting consisting of a stopper and of a heel able to cooperate respectively with the toe and the heel of a ski boot. This mounting area of the binding is centered relative to the mounting point in the middle of the shoe.
  • skis have a very deep dimension line, and therefore have a relatively small width in the middle zone corresponding to the zone of mounting the binding.
  • the assembly consisting of the stop and the heel piece of the binding enclosing the rigid sole of the shoe, clamp the board by modifying its intrinsic characteristics of stiffness.
  • a problem which the invention proposes to solve is that of the unlocking of the ski, in other words the problem of interference of the rigidity of the whole binding / shoe with the intrinsic rigidity of the board.
  • the stopper allows the efficient transmission of forces from the skier's foot to the gliding board, and more precisely towards the edges so that the ski is efficient and reactive. In other words, it is important that the stopper is firmly and directly secured to the board.
  • the binding stopper should be firmly and deeply anchored in the gliding board.
  • the invention therefore aims to solve all of these problems.
  • this ski has a different thickness in the area of mounting the fixing stop relative to the thickness of the mounting area of the heel of the binding.
  • the upper surface of the board in this area therefore has a stepped surface.
  • this stepped area which constitutes the thickness of the enhancement and the point of support of the platform on the board.
  • the front part of the plate supporting the binding stop can be firmly anchored in the ski area the thicker, while its rear part constituting the platform of the platform supporting the heel of the binding is not rigidly linked to the ski.
  • the combination of the stopper and the thin plate constitutes a relatively non-deformable assembly capable of directly transferring the forces of feet of the skier towards the ski edges, guaranteeing maximum precision in driving the ski.
  • the rear part of the plate is floating in relation to the rear of the mounting area of the binding.
  • the rear of the plate is cantilevered relative to the above the ski.
  • the invention by fixing the heel piece on a plate detached in this area on the upper surface of the ski, ensures total unclamping thereof.
  • the rear part of the plate is mounted with sliding capacity in relation to the board.
  • the ski may also include a wedge interposed between the rear part of the plate and the portion of the ski corresponding to the rear level of the mounting area fixing.
  • This wedge is capable of sliding relative to the ski in the rear part of the mounting area of the binding. In this way, the plate is not cantilevered and allows good transmission of the forces exerted from the shoe to the ski.
  • this wedge has elongated lights in the longitudinal direction of the ski. These lights are intended to receive pawns of guide mounted on the ski in the rear portion of the mounting area of the fixing to allow the displacement of said wedge, in a direction longitudinal, maintaining good lateral centering.
  • the connecting screws of the heel cross the plate and grip in the wedge without reaching the ski.
  • the wedge may have recesses intended to lighten it.
  • the ends of the mounting screws of the heel piece fits inside these recesses, thus avoiding their contact with the hold.
  • the plate has a rear end curved downwards and comprising a segment parallel to the upper face of the board, this segment being able to slide relative to the rear portion of the zone mounting mounting.
  • the aforementioned segment may include lights cooperating with studs mounted in the board as already explained.
  • the shim interposed between the plate and the upper face of the ski may be made of a deformable material, for example elastomeric, to allow the rear part of the plate to be moved by compared to skiing by shear deformation of the material constituting the wedge.
  • the lower surface of the rear part of the plate as well as the upper surface of the ski in the rear part of the mounting fixings are fixed, for example by gluing to a material elastomeric, that is to say capable of deforming in shear. So when the plate, and more precisely its rear part moves relative to the face upper part of the ski, the block or pad made of elastomeric material deforms and thus dampens part of the flexion deformation movements of the ski.
  • the ski also comprises return means capable of opposing the sliding of the rear part of the plate.
  • the return means cause the very rapid return of the board to its natural position, when the cause of the deformation has disappeared.
  • This assisted return movement helps to energize the board and improves driving the ski, especially when practicing slalom.
  • these return means can be constituted in particular by springs interposed between a stop located on the upper surface of the ski and a stop located on the plate.
  • These return means can be constituted by studs or buffers elastic or even hyper elastic working in compression.
  • the underside of the plate can follow a complementary shape allowing the good transmission of efforts and supports.
  • Figure 1 is a side view of a ski made according to a first form of the invention.
  • FIG. 2 is a detailed top view of the ski illustrated in FIG. 1, in the skate area, and in which the platform plate has been removed.
  • Figure 3 is a section along III-III of Figure 2.
  • FIG. 4 is a view of the single plate removed in FIG. 2.
  • Figure 5 is a side view of a ski made according to a second form of the invention.
  • Figure 6 is a detailed sectional view of the mounting area of the binding of a ski produced according to a third embodiment.
  • Figure 7 is also a detailed sectional view of the mounting area fixing a ski produced according to a fourth embodiment.
  • Figure 8 is a side view of the skate area of a ski according to another variant.
  • Figure 9 is a top view of Figure 8.
  • the ski (1) according to the invention is remarkable in the mounting area of the binding.
  • This area (2) of mounting of the binding is defined in a standardized way, and corresponds to the area in which the stop (3) and the heel piece (4) of the binding are mounted on the board (5).
  • the mounting area of the binding has a length between 30 and 50% of the carrying length of the ski, which is defined between the front (8) and rear (9) contact lines as shown in Figure 1.
  • front of the front contact line (8) is the spatula (6), while in rear of the rear contact line (9) is the heel (7) of the ski.
  • the ski (1) comprises a rigid plate (10) on which are mounted, for example by screwing, the stop (3) and the heel piece (4) fixing.
  • This plate (10) can, for example, be a metal plate of four millimeters thick.
  • the board (5) has a difference in thickness between the front and the rear at the level of the area (2) for mounting the binding.
  • the front portion (12) of the area (2) for mounting the binding has a thickness (e 1 ) which is clearly greater than the thickness (e 2 ) of the board (5 ) at the rear portion (13) of the mounting mounting area (2).
  • the thickness (e 2 ) of the board (5) at the rear level (13) of the area (2) for mounting the binding corresponds, by continuity, to the thickness of a board (5) standard in the part rear (15) of the pad, that is to say about 15 mm while the thickness (e 1 ) is about 25 mm.
  • the front part (20) of the plate (10) is mounted rigidly on the front portion (12) of the mounting area (2) of the fastener which extra thickness form.
  • This assembly can be done either directly by the specific screwing of the i plate, either by screwing the fixing stopper through the plate which then extends into the internal structure of the board.
  • the rear part (21) of the plate (10) is capable of sliding relative to the board (5) to ensure the unclamping the ski, in other words, not giving the overall stiffness of the ski a fraction inherent in the stiffness of the sole of the shoe.
  • the rear part (21) of the plate (10) rests on a slide (25) which is itself in contact by its face lower (26) to the upper face of the board.
  • This slide (25) can be profiled at the front to match the shape of the slope (27) of the change area board thickness (5).
  • the rear part (21) of the plate (10) is integral with the slide (25), by any known fixing means, in particular in the case of Figures 2 to 4 by the holes (38) for mounting the heel.
  • the slide (25) is slidably mounted relative to the board (5) to authorize the unlocking of the ski.
  • this slide (25) of general shape rectangular, has oblong lights (30) inside which penetrate pins (31) integral with the upper face of the board.
  • the geometry and the number of lights and pawns are not limited to the illustrated form, but can be adapted according to the materials used and the general dimensions of the hold.
  • these pins (31) are supported in order to maintain the plating of the slide (25) on the ski despite the bending of the latter.
  • the plate (10) can optionally, according to Figure 4, have a plurality screw holes (39, 38) for mounting the toe (3) and the heel piece (4).
  • This plate (10) also has at the front level (20) screw holes (36) allowing it to be firmly anchored in the thick part (12) of the zone (2) mounting the fastener.
  • the screw holes (36) of the heel piece are threaded while the screw holes (38, 39) of the stopper do not are not necessarily.
  • this joining of the plate of the board can also be made by the holes (39) for screwing the stop (3) of the fixing according to Figures 2 to 4.
  • the lights have a return means, by example a spring (40) which, working in compression opposes the displacement of the slide (25) relative to the ski.
  • a return means by example a spring (40) which, working in compression opposes the displacement of the slide (25) relative to the ski.
  • springs (40) or more generally the return members have an effect boosting on the ski, for example at the end of a turn. Indeed, in the case where pressure is exerted on the ski so as to make it bend by bending, the slide (25) being rigidly connected (38) to the plate (10), this assembly as well as the binding / shoe assembly does not undergo any length modification. So there is relative displacement of the rear mounting area (13) of the binding, and more specifically of the pins (31) linked to the ski with respect to the lights (30) of the slide. It follows that the springs (40) are compressed. When the impulse of the skier at the end of the turn disappears, the return members (40) accelerate the backward movement of the ski (13) relative to the plate (10), or in other words, bring the board (5) into a more flat configuration.
  • return members can be made so extremely varied, and are not limited to the embodiment of Figure 2 corresponding to springs.
  • the plate (10) has two shims (70, 71) under its lower face, in its rear zone, one of which (70) is integral with the board, while the other (71) is integral with the face bottom of the plate (10).
  • the rear wedge (70) has on its upper face screws or pins (74, 75) with shoulder intended to penetrate into the openings (72, 73) arranged on the plate (10). These pins (74, 75) are intended to prevent any displacement transverse of the plate (10), and to guide the plate (10) longitudinally during the bending the board. The shoulders of the pawns (74, 75) prevent the displacement of the plate (10) upwards.
  • the shim (71) is in turn secured to the plate (10) by a screwing or any other appropriate means.
  • the space between the shims (70) and (71) accommodates a spring (76) working in compression, and the ends of which come into contact with the shims (70) and (71).
  • the plate (10) has an opening (77) allowing to visualize the state of compression of the spring.
  • the high ends of the pins (74, 75) slide inside the lights (72, 73) by guiding the longitudinal movement of the plate (10).
  • the invention is not limited to the embodiment illustrated in FIG. 1, but covers other variants in which the rear part of the platform is not slidably mounted relative to the upper face of the board, but is simply mounted cantilever or floating relative to this upper face of the board.
  • the plate (32) can be fixed in its front part (33) to the front zone (12) for mounting the ski bindings (5) while the rear part (34) of the plate is cantilevered above the area rear (13) for mounting the fasteners.
  • the plate (50) can rest directly on the upper face (51) of the ski, at its rear end (52). To do this, the rear end (52) of the plate is inclined downward, and has a segment (53) which rests on the upper face (51) of the ski in the rear mounting area fixings.
  • the space (55) located between the plate (50) and the upper face (51) of the ski in the thinnest part (13) of the zone (2) for mounting the fixing can be hollowed out.
  • such a space is filled with a easily compressible material to avoid snow accumulation.
  • the segment (53) forming the rear end of the plate (50) has a light (54) equivalent to that provided in the slide (25) of the embodiment of FIG. 2.
  • This light (54) receives a stud (56) firmly anchored in the structure of the board (5) to ensure the longitudinal guidance of the displacement of the plate (50) while allowing a certain consecutive movement when bending the ski.
  • the rear part (61) of the plate (60) rests on an elastomeric stud (62) able to deform when the ski bends.
  • the elastomeric stud (62) is fixed under the plate (60), and on the face upper (63) of the ski, to allow good lateral guidance of the plate (60) during of its movements in relation to the board.
  • this pad In the case where this pad is made of a viscoelastic material, it allows to provide some damping of vibrations. In the event that this pad is made in an elastic or even hyper elastic material, it then ensures a some boost to skiing.
  • the mounting area (2) of the attachment is extended forward by a boss (28) of additional thickness, substantially equivalent to the thickness of the plate forming the platform in order to achieve an aesthetic integration thereof.
  • the platform (10) is integrated into the upper face of the ski and is not prominent, which avoids the risk of injury.
  • the ski according to the invention has multiple advantages, and in particular ensures a good unlocking of the ski, while allowing a firm and very rigid connection of the fixing stop by compared to the board ensuring high precision in skiing.
