  • the greater height of the structure means that the power transmission via the binding into the sliding element can be increased. Furthermore, the additional height on the ski or snowboard and the overhanging guide rails change the volume and shape of the gliding boards. Due to the fact that the guide rails are overhanging, the sliding sports board is wider in its width, across its base, and the new lateral outer profiles are reshaped. This means that the structure is wider than its base and tread.
  • the height or thickness of the gliding boards is determined by the height of the structure, connected to its base or connection, with a conventional ski or snowboard and its thickness.

  • the lateral outer edges of the tread at the base are reinforced on the skis and snowboards with steel edges so that they take the lead on the ski slope or on other hard surfaces, when cornering and also work optimally on hard icy slopes and do not slip away. It is also possible for the edges on the overhanging guide rails to be shaped in such a way that, in the case of a certain lateral position in the curves, on the runway, they hit these and lead as additional side edges. These additional side edges are reinforced with steel edges for driving on ski slopes for this purpose. This gives the gliding boards the advantage of optimized grip on the ski slopes thanks to the additional edge grip.
  • the height of the structure also mostly determines the mounting heights of the bindings and their connection to its gliding board and its base.
  • the bindings can be mounted higher and thus the power transmission to the outer edges of the slide sports boards is determined.
  • the shoes due to the additional widths and heights of the superstructures and with their guide rails, the shoes have more space in relation to their narrower bases, which give the sliding boards the tread when driving on the slopes or on hard surfaces.
  • This has the advantage that the bases of the skis and snowboards can become narrower and the shoes no longer stand over the outer edges. As a result, the shoes no longer hook on hard surfaces and therefore have less resistance surfaces in braking powder that brake when driving.
  • sliding sports boards with narrower bases can be driven more dynamically.
  • the minimum width is given by the shoe, binding or foot lengths or the shoe, binding or foot widths, the driver of the new sliding sports boards, and the positions, how much the lateral outer edges of the guide rails, over the lower or the upper lateral outer edges the bases stand.
  • the determination of the guide rail shapes i.e. their new outer profile shapes, gives the sliding boards their effective widths.
  • this has the advantage that the running surfaces of the gliding boards are increased by the widths and heights of the guide rails.
  • the overhanging guide rails have a controlling and optimizing effect when driving.
  • the shapes, dimensions and positions of the guide rails on the superstructure are determined so that they slide into the sunken boards , give optimized cornering when driving.
  • the treads of the guide rails whose treads are above the base, optimize driving behavior when cornering and driving straight ahead, in powder snow and in water.
  • the treads are then automatically enlarged in powder snow and water because when the boards sink in, the base treads increase by the widths and heights of the guide rails.
  • the running surfaces of the guide rails are not used as running surfaces because they are located above the running surface of the base.
  • the outer edges of the overhanging guide rails can be shaped in such a way that they can lead in curves, on hard surfaces, with a certain lateral position.

  • the rails hang less in the curves due to the optimized displacement and the optimized flow of snow or water to the side and under the gliding board.
  • the snow or water is redirected. As a result, less snow or water flows over the gliding boards when driving. This creates less resistance and the gliding boards become faster. This also creates fewer areas, such as on the side edges of the gliding boards, on the bindings or on the shoes of the drivers, on which the new gliding boards are hit by unwanted snow or water currents that occur when driving, and thereby slowed down.
  • the snow or water is displaced from the gliding board and optimized.

  • the advantages of landing jumps are that if the landing is not ideal, the additional outer profile shapes can still save it.
  • the enlarged, lateral outer profiles hang less in powder snow and in the water and can therefore save you from a fall in the event of a critical, twisted landing.
  • the advantages of landing after a short take-off and when traveling at high speeds are the same as for critical landings after jumps.

  • additional edges on the overhanging guide rails on the body can be reinforced with steel edges or plastic edges. These edges on the guide rails, depending on how much they stand over the outer edges of the base, can take the lead when the gliding board slides and curves.

They steer better when driving straight ahead and allow more stability in corners and prevent them from sliding sideways in steep corners. There are different options where and how many fins are attached. The number, positions and dimensions of the fins are determined depending on the use of the gliding board and their requirements when driving, in water or snow. Fins can be attached to the front, back or in the middle. The same also applies to the gliding boards, such as skis and snowboards, which are mainly used in deep snow.

  • the tread of the base can have one or more concave channels, all of which are inserted between the two lower, lateral outer edges of the base in the tread of the base on the gliding board. These channels run at least partially or along the entire length of the tread.
  • the concave channels on the tread of the gliding board give the snow and water new directions of flow. These are thus optimized and leave the Gliding sports boards glide better and faster, when driving straight ahead and when cornering.
  • the tread at the base of the gliding board can have air channels.
  • the shapes of the air ducts in cross-section to the direction of travel are individually shaped. They give the gliding board more buoyancy.
  • the airstream and the headwind that arise when driving the gliding boards are channeled with the air channel on the tread and the wind flows optimally under the gliding board.
  • the air channels are inserted at least partially or along the entire length of the tread and can also be inserted in combination with the concave channels and the fins on the tread of the gliding board.
  • the sliding sport boards are optimized with the insertion of the concave channels and the air channels on the tread of the base, more aerodynamically and while sliding. The sliding sports boards get even more lift and are faster and more dynamic for driving.
  • the shape of the body and its overhanging guide rails are also aerodynamically shaped.
