  • the invention relates to a snow gliding element, in particular a Ski or a sledge or a snowboard, with a sliding element body, which has a surface and a lower surface, the lower surface in partial areas along the longitudinal axis of the snow gliding element in the envelope a convex shape having.
  • tread known from snow skis, which is a convex Have shape.
  • US 5,673,926 shows a ski that is very short Design, the underside of which has a prism shape in the front area has under the foot of the skier in a flat bottom with rounded on the side, raised and thus convex Area.
  • US 4,974,868 shows two configurations of snowboards which each have three broad transverse grooves. Furthermore but is the bottom surface when executed after the first three Figures have a convex lower surface and the lower surface in the execution after the last three figures is with provided a convex lower surface on the side edges concave into a cutting side edge.
  • the US 4,974,868 should enable a simplified turning of the snowboard, because the tilting movement over the convex underside the snowboard's edge is easier to reach into the snow can. There is also only a small proportion of the snowboard actually in contact with the snow.
  • the CH 600 905 shows a convex shape of the sole with longitudinal embedded ridges.
  • All the known snow gliding elements described describe convex Ski surfaces that are easier to steer due to lateral loads want to ensure the ski or snowboard.
  • the ski surfaces are designed like a seesaw, with side edge reinforcements partially drawn in, i.e. Edge elements that protrude beyond the convex end edge surface, for better guidance and no easy overturning to realize. But this is not a result of shifting the pressure point Controlled control of the snow gliding element possible.
  • the invention lies Task based on a snow gliding element of the aforementioned To be designed in such a way that. Pressure point shift one self-stabilizing control of the snow gliding element achieved becomes.
  • the underside according to the invention has an overall convex Cross-section, which is structured by several leading edges becomes. These leading edges create the bottom view waisted sliding surfaces. From the center to the side, the Waist gradually, i.e. the leading edges are in the Bottom view increasingly curved longitudinally. This creates the following effect: If the vehicle is loaded laterally asymmetrically, So the pressure point of the weight moves from the middle, the trunk tilts to the corresponding side. Come through this more curved leading edges are used, which leads to this that the vehicle is turning toward the shifted pressure point describes. The curve radius increases with increasing weight shift smaller.
  • the effect according to the invention is due to the variable contact surface achieved with all appropriately designed sliding elements.
  • FIG. 1 shows a tailored snowboard 1 according to a first Embodiment of the invention in a bottom view. It has a sliding element body 2, of which only the Bottom 3 can be seen. This consists of several, in itself concave, aligned in the longitudinal direction 5 of the snowboard 1 Wells 6. There are five wells or grooves 6, which are arranged side by side. With the lines 7 are the Designated contact lines on which two adjacent depressions 6 in a discontinuous manner, i.e. in an edge, or in rounded To merge into one another.
  • the reference numeral 17 is the outermost one Edge that denotes the area of transition to Surface 4 of the snowboard 1 forms as shown in FIG. 2 is recognizable.
  • Edges 7 and 17 are leading edges that are in the bottom view Form waisted sliding surfaces. From the middle to the side the waistline increases gradually, i.e. the leading edges are increasingly more longitudinally curved in the bottom view.
  • FIG. 2 shows the snowboard 1 according to FIG. 1 in a dimetric View.
  • the Edge 17 is the lower edge of the snowboard side surface 8 which corresponds to the thickness of the material of the sliding element body 2.
  • the side surface 8 could also be very high be smaller, and in the most extreme case reduce to edge 17.
  • the edges 7 are shown in dashed lines.
  • FIG. 3 and 4 show a side view and a front view of the snowboard 1 according to FIG. 1 on a support 11 in tilted position or in a tilted position.
  • the edition is usually not a rigid, not compressible element but can by a snow gliding element 1 as shown here be pushed in (lightly).
  • the Number of leading edges 7 (17) or sliding surfaces is a minimum of three, so there are a minimum of two wells 6. Im 1 to 4 embodiment shown five depressions 6 and six sliding surfaces. The number of leading edges 7 can also be chosen larger, ten being one possible reasonable size is. However, there is also a larger number of these structures possible.
  • FIG. 5a to 5d show cross-sectional views of various Embodiments for snow gliding elements, wherein Fig. 5b a less strongly curved modification of the embodiment 1 shows. 5a has eight wells and thus nine leading edges 7 (17).
  • the depressions 26 Grooves that are rather small in width compared to the convex Bottom surface 37.
  • the depressions 36 are asymmetrical designed and merge at edges 7. The The region of the greater curvature lies with these depressions 36 away from the center line of the ski towards edges 17.
  • FIG. 6 shows a front view of a snow kickboard of the invention, wherein Fig. 7 is a bottom view and Fig. 8 is a 6 shows a perspective view of the snow kickboard according to FIG.
  • the waisted board has the in connection with Fig. 1st to 5 described recesses 6 and edges 7.
  • a holding plate 14 mounted on the a holding and driving rod 15 is attached, the two Support struts 18 is held.
  • the driver's footprint 24 includes some preferably rough strips 25 for a secure one Stand.
  • the rod with grip ball made of soft material also serves here as with street kickboards to control the device.
  • the roughened and profiled stand area 24 optionally adjustable hand straps (similar to those on windsurf boards), or holding hooks for the feet or for one foot mountable. Furthermore, one can be kicked with the rear foot Brake, which acts directly on the snow surface via levers, to be assembled.
  • the footprint 24 is concave in cross section designed to increase the pressure of the feet around the edges. For pulling uphill, the rod 15 can be folded forward, so that you can pull the device comfortably behind you. For transport, it can also be folded flat over the back Fold the fuselage.
  • the waist to be seen in FIG. 7 is essential for better cornering stability of the sports equipment.
  • the line 6 widens the structures 6. Because of the smaller one Curvature of the front part up to line 32, the location of the least Width of the board, and the shorter, less elongated and narrower end of the board with narrower recesses 6 at the locally widest point there (marked with the transverse line 33) it is easier to screw in.
  • FIG. 9 shows a front view of a snow sled according to the invention, a perspective view of the same and a bottom view of the snow sledge according to FIG. 9.
  • the design of the underside is similar to that of the carriage previous embodiments.
  • the essentially convex Underside with edges 7 is interrupted by depressions 6. As can be seen in the bottom view, these are in Seen longitudinally from the front, first widening up to a line 31, then narrowing to the waist on the line 32 and finally broadening to the level in front area, which is achieved on line 33.
  • An advantage of the carriage according to FIG. 9 is that it is firmer (Snow) underlay only a small contact area, namely the area of the edges on which the support rests, and thus a higher contact pressure is achieved.
  • a soft snow surface bag conventional sledges.
  • the one proposed here Sledges then distribute the bearing surface over one large area, so that additional sliding surfaces in whole or in part are used. The gliding remains qualitative even then Good.
  • PU foam parts also come EPP (Expanded Polypropylene) parts.
  • EPP Expanded Polypropylene
  • inflatable Seat cushion with several chambers. This ensures one comfortable suspension and good cold insulation with low weight , Optionally, it is completely in the same technology as high quality inflatable boats manufactured, i.e. the bottom surface will made of a rubber-like soft plastic.
  • FIG. 12 shows a perspective view of a Downhill skis according to the invention, wherein Fig. 13 is a front view and FIG. 14 shows a bottom view of the downhill ski according to FIG. 12 represent.
  • the waist of the ski also appears in this figure with a narrowing of the depressions 6 and a corresponding one Lines of the edges 7 clearly stand out.
  • the driver of the snow gliding element is for cornering to set a certain inclination of the same. This is about the Convexity, i.e. the angular arrangement of the sliding surfaces, adjustable, the width also plays a role. Through the angle and the width can adjust the driving dynamics, the means how much the snow gliding element falls into the curve or must be pressed into a curve. With progressive driving dynamics easy curves with minimal pressure point shifts drive while cornering only through strong pressure point shifts can be achieved. A snow gliding element, a snowboard, for example, is therefore a lot in curves more stable, because you do not drive on an edge 7 but ever according to snow hardness and hull design also on several gliding surfaces.
  • the manager is through the design of the leading edges in the Cross-section largely depending on the medium to be driven change and optimize. Furthermore, you can be the manager Define asymmetrically, for example on skis.
  • the edges are designed in the form of scales in the embodiment according to FIG. 5d, so that when the ski tilts it gently slips away instead of steering in the wrong direction. simultaneously is the guiding effect against downhill forces and centrifugal forces with such a ski much better than with usual.
  • leading edges according to FIGS. 5a to d have different degrees of cross-section, so that different guiding characteristics at different angles of inclination be achieved.
  • this embodiment designed hull takes Contact pressure of the front and rear end of the fuselage with increasing Inclination due to shape. So is a hull at the bottom not concave in the side view like conventional hulls spanned but slightly convex. This is in Fig. 3 with the Reference numeral 47 for the raised front nose of the board shown. The tip of the snow gliding element lies in the Not at rest.
  • simple snow gliding elements apply as a blow molded part or as a rotational molded part
  • injection molding or Drawing parts are designed and in the higher-quality segment consist of fiber-reinforced plastics.
  • a sandwich construction is optional.
  • Leading edges are made of metal.
