Definitions

  • the invention relates to a snow sliding board according to the preamble of the independent claims.
  • skis and snowboards are often placed on one edge when cornering and, ideally, the curve is driven completely on one edge. A sideways drift across the direction of travel can thus be reduced and the curve can thus be traversed faster. From the “carving" of these tracks, the name "carving” is derived.
  • the design of the tread in the top view (outline) and in the side view (side elevation) is relevant for the behavior of a snowboard.
  • snowboard boards In order to make carving possible, snowboard boards have a sidecut in plan view, which in combination with the self-adjusting. Deflection gives the effectively driven radius.
  • a problem of today's snow gliding boards is that although the sidecut in the floor plan is intended for carving, the side elevation has never been adapted to the new circumstances.
  • the vertical curvature in the side elevation and the lateral sidecut in the floor plan of the snow gliding boards currently on the market are based on empirical findings of the manufacturers. Also, the ends, especially the blade (front end) of today's snow gliding boards are made according to traditional, never changed templates. The present forms of snow gliding boards are not optimally designed for carving, so that when driving an increased resistance arises, resulting in an unnecessary reduction in speed.
  • the ski industry has been trying to optimize the equipment, but without success, because the mechanics are considered too two-dimensional.
  • the skier needs the lateral outline to make a bow. He needs the tip (shovel) so that the device does not stick.
  • the blade Seen in a side view, the blade typically extends vertically beyond the central region in a conventional snow gliding board. In particular, when cornering the blade forms a significant resistance due to its strong curvature and causes unwanted deceleration.
  • FR2786108 (Salomon SA) shows a ski with a pointed bend, which is on the one hand particularly long and on the other hand wide.
  • the length of the Spitzaufbiegung ie the distance between the foremost point of the ski and a front contact line, at which the ski touches the base for the first time, is between 300 mm and 500 mm.
  • the greatest value of the width of the Spitzaufbiegung is greater than or equal to 105 mm. This is to ensure that the ski is easier to drive in powder snow without changing its driving characteristics on hard snow.
  • US6986525 (Rossignol SA) according to the title refers to a snow sliding board with an adapted blade and tail curvature.
  • One goal is to show a short waisted ski whose load-bearing surface is said to be enlarged compared to the prior art and which shows a more progressive behavior when the curves are introduced.
  • an ISO standard 6289 is used protruding leading snowboard is pressed onto a flat surface, so that it rests in the middle area on this fed. The resulting contact area is limited by a front and a rear contact line (definition according to ISO standard 6289).
  • An object of the invention is to show an improved snow sliding board, which has less resistance and better traction, especially when cornering
  • a sliding surface of a snow gliding board has the following areas in side elevation seen from the front to the rear: concave Spitzaufbiegung, which forms the blade in the front region; convex leader (middle region); concave Endankbiegung, which opens in the rear area to the rear
  • the middle area has a positive, upwardly sloping convex curvature, which merges in the region of the ends in concave negative curvatures
  • the areas in which the sign of the curvature change are called saddle points
  • the curvatures are chosen so that laid on a plane unloaded Schneegleitbrett only in the region of its concave Endkurümmache, the contact areas of the sliding surface, rests and lifts in the middle of this (bias).
  • the function of the invention is not adversely affected by a geometric deviation, provided that the curvatures, their relationship to each other and the transition points (saddle points) are arranged so that the inventive kinematics ("roll effect", see below) while driving
  • the curvature direction of the leader between the peripheries (blade and tail) is defined as a positive, convex curvature, and the peripheral curvatures in the area of the bucket and tail are defined as a negative, concave curvature.
  • Any existing straight sections between the convex and concave areas act as a limitation of deformation in that a Schneegleitbrett can only be bent so far until they lie (both obliquely and in the flat state) along its entire edge length.
  • Straight areas act in particular as a deformation limit when the curvature changes on the opposite side, eg. from concave to convex.
  • Such straight portions are understood in the context of the invention described herein as positive, convex curvatures, since they behave essentially as such.
  • the following elements are distinguished in the description of the boundaries of the sliding surface (viewed from front to back): pointed end, sidecut, end termination.
  • pointed end For the description of the geometry of the sliding surface in the side and in the ground plan, simplified arcs or straight lines are used, as they have geometric points that are helpful for the explanation. However, instead of circular arcs and straight lines, other elements such as ellipse, clothoid, parabola, etc. may be used to define the geometry. As quadrant points (extreme points) points are called, the snowboard at the largest resp. smallest perpendicular distance to a longitudinal axis of the device.
  • the pointed end and end termination begin at a forward quadrant point, respectively, at a rear quadrant point, which form the transitions to the sidecut.
  • a mid-quadrant point can be found in the narrowest part of the sidecut.
  • Saddle points are understood as areas in which the sign of the curvature (positive, negative, respectively convex, concave) changes. These are of particular relevance for the definition of the lateral crack of the sliding surface
  • the snow sliding board when the snow sliding board is guided on an edge through a curve, it deforms elastically in the central region as a result of the loads occurring, so that the initially convex curvature becomes temporarily a concave curvature.
  • the lateral sidecut and the upstand angle angle between the sliding surface and the ground when the snow sliding board is placed on the edge
  • the side edge lying on the ground ideally describes a substantially circular path, which in the Ideal case corresponds to the driving curve
  • the bearing areas and saddle points in the blade and tail areas are very close together, the distance between these two areas is typically only 2% to 4% of the total length of the snow gliding board.
  • the saddle point often can not be determined in the sense discussed here, since the sliding surfaces between the convex and the concave portions just identify intermediate pieces, which act as a deformation limit.
  • the mean radii of the end regions (blade, tail) are around 500 mm and the mean radii of the prestressing around 13,000 mm to 14,000 mm.
  • the blade area (tip to landing point in unloaded condition) usually covers about 10% of the length of the snowboard so that the saddle point is around 12% to 14% of the total length.
  • the support area In the rear area of the support area is about 2% to 4% and the saddle point about 4% to 5% from the end (100%) away
  • the support area shifts only slightly, since the support area in the unloaded state and the saddle point very close lie together, resp. straight sections between the curvature changes prevent the deformation.
  • the tip always retains approximately the same direction with respect to the ground, resp. the direction of travel.
  • a highly tilted, curved tip is required so that no insertion results
  • a conventional snow sliding board regardless of the deflection, always pressed in about the same area the strongest on the ground areas with strongest Edge pressure is comparatively close to the end regions.
  • An idea of the invention is to achieve an optimal interaction of the physics when gliding and the mechanics of the gliding device. This goal is achieved by a deformation-dependent change, respectively, by an inventive vote of the side crack and the floor plan while driving. a shift of the high pressure along the edge in the form of a controlled rolling effect is achieved. Edge areas with high edge pressure are temporarily shifted towards the middle of the snow sliding board and the influence of the edges in the critical end areas is thereby reduced.
  • Another idea of the invention is that a load-dependent modified Spitzaufbiegung when edge up (put on the edge) of the sports equipment an important role for the swing initiation, respectively. control can take over. This is not taken into account in conventional designs
  • An embodiment of a snow gliding board according to the invention has a curvature transition (saddle point) between convex pretension radius and concave peripheral bends, which, compared to a conventional snow gliding board, is arranged in the longitudinal direction farther towards the center (50% of the length of the snow gliding board), so that between the contact point and the saddle point a rolling surface is formed, which allows a variable edge force distribution, especially when cornering in the folded state
  • the edge region with high load temporarily towards the center of the snowboard and the critical edge areas in the inlet area are relieved.
  • the Aufrollf Anlagen results in a participatedkanteten Schneegleitbrett due to the external forces acting by the Schneegleitbrett is deformed so that a "deepest edge region", which forms the relevant direction of travel contact between the edge and a substrate, due to the self-adjusting deformation along shifting the edge
  • the area of the snowboard which lies in the longitudinal direction before the deepest edge area, it is practically not loaded and thus retains essentially its original shape.
  • the invention has the advantage that due to the rolling effect, in particular the end portions of the snow gliding board can be made much stiffer compared to the prior art, so that less flutter and high-frequency interference occur, as they typically occur at high speeds.
  • the distance between the support area and the saddle point, and the radii of the end portions are selected so that a load-dependent rolling at least one end portion is achieved.
  • Rolling up here means a temporary, load-dependent lifting of the end regions as a result of a displacement of the support region relative to the longitudinal center and an associated unrolling along the concave sliding surfaces in the end regions.
  • the average radii of curvature in the support area are also much larger compared to conventional snow gliding boards. In a preferred embodiment, they are about 3000 mm and are thus about 4 to 6 times larger than in a conventional snow gliding board.
  • a snow gliding board result, inter alia, when traversing mountain edges, where as far as possible no changes of direction are to be made, the momentum control on the runway, in deep snow or in door runs.
  • the sliding speed will generally be higher in all snow conditions and applications, as the strain resulting from the load results in an optimized sideline resulting in less resistance and reduced susceptibility to external disturbances.
