Definitions

  • the invention relates to a device for non-skid guidance of a ski on a hard-pressed or icy road, which device has at least one web attached to the side of the ski, which extends over a part of the inner side surface of the ski that is in the region of the ski binding.
  • skis used in many known designs have a tread on the carriageway, on the longitudinal edges of which hard metal strips are arranged as ski edges, which above all protect the highly stressed longitudinal edge.
  • such ski edges also offer protection against lateral slipping.
  • this protection is not guaranteed on hard-pressed or icy ski slopes, especially on steep slopes. Efforts have therefore not been lacking to ensure protection against lateral slipping, even under extreme driving conditions, without making it difficult or even impossible to guide the ski.
  • edge of the web directed towards the roadway is at most flush with the plane of the tread of the ski.
  • a ski 1 is partially shown, on the surface 2 of a toe-side binding part 3 of a safety ski binding is attached.
  • a web 5 is fastened with two screws, the edge of which is directed towards the road 7 and is flush with the running surface 9 of the ski 1.
  • the web 5 lies on the side surface 4, but the web 5 could also be inserted flush in the side surface 4.
  • the thin-walled web 5, which is drawn too thick in FIGS. 2-4 practically does not contribute to an increase in driving resistance.
  • 2-4 shows a ski edge 10 lying in the tread 9 in the form of a metal strip, which however does not form part of the invention.
  • the edge 8 of the web 5 forms a cutting edge 11 which lies on the outside of the web 5 and at a distance from the side surface 4. If the formation of the cutting edge 11 is dispensed with, the beveling of the edge 8 is omitted.
  • a hollow grinding-like edge 8 can also be provided, as is also used in ice skates.
  • the cutting edge 11 is flush with the plane of the tread 9, while in FIG. 3 it is set back by a small amount z from this plane. With this reset it is achieved that the web 5 is practically ineffective when the ski lies smooth on the road 7.
  • the edge 8 or the cutting edge 11 becomes effective, as can be seen from the greatly enlarged FIG. 4.
  • the web 5 ends in the extended stel development of its cutting edge 11 by the amount z above the tread 9 of the ski 1. Nevertheless, it can be seen without difficulty that the cutting edge 11 can penetrate the road 7 and thus reliably prevent the ski 1 from slipping off.
  • the edge shown in dashed lines in FIG. 4 shows the flush position of the cutting edge 11 with the running surface 9 of the ski 1. It can be seen that in this case the cutting edge 11 penetrates the driving surface 7 earlier, ie with a smaller inclination of the running surface 9 towards the road 7 can.
  • Fig. 5 shows an arrangement in which the web 5 is slidably attached to the side surface 4.
  • the bores 12 in the web 5 have an oval shape, so that after loosening the screws 6 the web 5 can be brought into the flush position with the running surface 9 of the ski. If, on the other hand, the ski is used in soft or freshly fallen snow, the web 5 can be brought back to its previous position according to FIG. 5.
  • FIG. 6 and 7 show an embodiment of the device according to the invention, in which the transition of the web 5 from the back to the flush position is effected by the weight of the driver and / or by inertial forces exerted by the driver.
  • the web 5 is provided with oval openings 12 for the shaft of the fastening screws 6, the screw head being located in a likewise oval recess 13 in the web 5.
  • a step 14 is connected to the web 5, which, see FIG. 7, extends at a distance parallel to the ski surface up to the opposite side surface 4.
  • a compression spring 15, for example a leaf spring, as shown in FIG. 7, or a rubber spring is located in the space formed between the ski surface and the step bracket 14.
  • the Compression spring 15 exerts an upward force and holds the web 5 in its previous position, which also does not change when only about half the weight of the skier presses on the kick bar 14. Only when a certain limit force is exceeded, for example when shifting the body weight of the driver onto a ski or when an additional centrifugal force arises when a change of direction is initiated, does the compression spring 15 yield and the web 5 moves downward into the essentially flush position. 6 and 7, the sole 16 of a ski boot is shown schematically, which rests on the step bracket 14 and is otherwise held by the binding part 3 and the heel part, not shown.
  • the movement of the web 5 can be determined either by the size of the oval openings 12 or the oval depressions 13, but it is also possible to omit a limitation of the flush position, so that in extreme stress cases the web 5 extends beyond the level of the tread 9 can extend. During normal travel with corresponding changes in direction, on the other hand, the web 5 remains within the previous and the flush position.
  • the past position of the web 5 does not in any way need to correspond to the position with the distance z according to FIG. 3, rather this value can be larger, so that with normal the safety Driving no influence of the web 5 is noticeable.
  • the setting of the web 5 and the choice of the distance z must be determined individually for the individual driver, which can be achieved in that the screw 6 has an eccentric that lies in the circular opening 12 of the web 5 and allows any setting of the value z.
  • the web 5 does not have to be moved over its entire length from the previous to the flush position.
  • the edge 8 of the web 5 is subject to a certain amount of wear.
  • the web 5 can, however, be easily removed and the edge 8 reworked.
  • the web 5 as a whole only has to be replaced after it has been reworked several times.
  • the web 5 is expediently only attached to the inner side surfaces 4 of the skis, so that a web 5 is effective with each change of travel on one side or the other.
  • the web 5 is also possible to arrange the web 5 completely or only sunk in the side face 4 in the front side seen in the direction of travel, so that the risk of being attached is thus further reduced or avoided.
  • the recessed arrangement of the web 5, however, requires a corresponding recess in the ski edge 10 lying in the tread 9 and in the side surface 4.
  • the length of the web 5 can also be selected depending on the weight and driving style of the driver. In any case, the skis should be guided safely, including a slight change in the direction of travel during normal driving and, on the other hand, a safe hold of the ski without slipping on icy slopes is understood.
  • the web 5 can be relatively short and cannot exceed the area of the ski binding, i.e. about 40 - 150 mm long.
  • the arrangement of the web 5 in the region of the toe ball or forefoot is particularly expedient.
  • the dimension Z can be about 0.5 to 1.8 mm and the web thickness 1.5 to 3.0 mm.
