Definitions

  • the invention relates to a ski with a base body that has a tread, an upper side opposite the tread and two opposing side wall surfaces between the upper side and tread, and with a main side edge profile that delimits the tread in the longitudinal direction and adjoins a side wall surface, and with at least one independent additional side edge, which is offset above the tread in the direction of the top of the base body and protrudes laterally outwards over the main side edge profile.
  • edges or steel edges are generally referred to as edges or steel edges, since they are usually made of steel.
  • edges profiles or edges serve to achieve a better grip of the ski when it is tilted, in particular in the case of stuck and / or icy slopes, and additionally protect the edges of the tread of the base body against deliberate wear.
  • EP-OS-0 087 089 to provide, in addition to this main side edge profile, a further side edge which is offset above the tread in the direction of the upper side of the base body and which projects laterally outward beyond the main side edge profile, such that the free edge of the main side edge profile is a predetermined distance below the free edge of the additional side edge.
  • This construction ensures that the additional side edge does not become effective during normal straight-ahead driving, but, when the ski is inclined to a certain extent, it engages in the snow or ice in addition to the free edge of the main side edge profile and thus prevents the ski from slipping sideways , so that the user of the ski can drive through dangerous routes safely and at higher speed, since the additional edge ensures better guidance of the ski even on difficult ground.
  • the invention has for its object to provide an improved ski, in which the effectiveness of the additional side edge is guaranteed even under unfavorable conditions.
  • the snow discharge channel in the area of at least one side wall surface of the base body of the ski that the snow discharge channel, due to its dimensions, does not tend to fill with snow and / or ice particles even during normal driving, ie when the ski is not tilted that could subsequently affect the effectiveness of the additional side edge.
  • This ensures that the at least two free edges are securely gripped when the ski is tilted, the particular advantages of the snow discharge channel provided according to the invention being shown by particularly favorable guiding properties, since the snow or ice mass pressed into the snow discharge channel during tilting is caused by the pressure acting on it to a certain extent becomes a temporarily effective guide rib through which the tilted ski is guided laterally, as with a tongue and groove connection.
  • one suitably dimensioned snow discharge channel high shear or frictional forces between the ski still connected to the snow on the slopes on the one hand and snow or ice residues in the snow discharge channel on the other hand, which has the consequence that deposits that may be in the snow discharge channel fix, after a short time be swept away again by the snow or ice mass, which moves through the snow discharge channel in the sense of the desired management function.
  • each snow discharge channel is connected to the top of the base body via at least one passage, this passage being designed, for example, as an elongated hole.
  • This passage being designed, for example, as an elongated hole.
  • the advantage of the invention is that the additional edge (s) and the snow drainage channel (s) are clearly set apart from the edge which was originally present and function as separate edges.
  • the above statements make it clear that the basic idea of the invention can be implemented in different variants, it being important in all cases that the additional edges take effect at the desired time or at the intended inclination of the ski relative to the slope and that snow and ice can be discharged through one or more snow discharge channels.
  • the embodiment of the invention is not limited to use in alpine skiing, but can also advantageously be used in cross-country skiing, where more safety against slipping or especially during the skating step (siltoning technique) Breaking out of the skis is achieved In the case of runs which are given on cross-country trails as well as on downhill slopes, the measures according to the invention bring practically the same advantages as in downhill skiing.
  • the embodiment according to the invention can also be advantageously implemented in the case of wide individual skis - so-called snowboards and monoskis - in which case at least one additional side edge and the snow discharge channel on each longitudinal edge of the ski are preferable.
  • the additional side edge profiles in connection with an associated snow drainage channel enable higher cornering speeds even with a water ski, since the water behaves similarly to a more or less compact ice or snow layer at high running speeds.
  • FIG. 1 shows a partial cross section through a ski with a base body 1, which has a tread 2, an upper side 3 and a side wall surface 4, which in the exemplary embodiment merges into the upper side 3 via a rounded longitudinal edge.
  • a base body 1 which has a tread 2, an upper side 3 and a side wall surface 4, which in the exemplary embodiment merges into the upper side 3 via a rounded longitudinal edge.
  • One longitudinal edge - in FIG. 1 the left edge of the tread 2 - is provided with an inserted main side edge profile 5.
  • An additional side edge 6 is provided above the main side edge profile 5, which lies closer to the top 3 of the ski and protrudes outwards by a distance S from the main side edge profile 5.
  • a snow discharge channel 7, which in the exemplary embodiment has a rounded cross section.
  • the snow discharge channel 7 - the depth of the snow discharge channel is, for example, 5 to 10 mm - also inclines due to its dimensions and its cross-sectional profile under unfavorable conditions not to clog, so that a secure guidance through the free edge of the additional side edge 6 is guaranteed when the ski is tilted.
  • FIG. 2 In the exemplary embodiment of a ski shown in FIG. 2, only an additional side edge 6 is provided in addition to the main side edge profile 5, similarly to FIG. 1. Between these two edges 5, 6 there is again a snow discharge channel 7, which in principle again has a rounded cross section, but the rounding is approximated by individual, straight sections, which may be easier to manufacture in terms of production technology.
  • the special feature of the ski according to FIG. 2 is that a passage 10 leads from the snow discharge channel 7 to the top of the ski, the passage 10, as is clear from the plan view according to FIG. 4, having the shape of an elongated hole. From Fig. 4 it is also clear that there are several passages arranged at a distance from one another along the snow discharge channel 7.
  • the passages 10 are inclined obliquely upwards and backwards in the running direction of the ski, so that they can remove snow and ice particles from the snow discharge channel 7 well.
  • the embodiment according to FIG. 3 differs from that according to FIG. 1 in that two additional side edges 6, 8 are provided and in each case protrude outwards by a distance S, once with respect to the main side edge profile 5 or the additional side edge 6 , a further snow discharge channel 9 being present between the two additional side edges 6, 8.
  • the free edge of the additional side edge 8 is effective when the ski is tilted more strongly, the amount of snow or ice accumulating between the side edges 6 and 8 being discharged through the additional snow discharge channel 9.
  • passages 10 can go to the top of the base body 1 be present, starting from each of the two snow discharge channels 7, 9, so that consequently there are two rows of passages 10 offset from one another transversely to the running direction on the top of the ski.
