Definitions

  • the invention relates to a ski, in particular a cross-country ski or alpine ski, with a ski body, on the underside of which a tread is arranged.
  • Skis are known in various designs. This also applies to cross-country skis or alpine skis.
  • the object of the present invention is to create a ski which is especially suitable for so-called “skating” and in which it is important to obtain a loss that is as loss-free as possible, in particular on icy terrain, without impairing the gliding ability mentions that skating is a kind of ice skating technique. Furthermore, the invention is generally intended to provide a ski, in particular a cross-country ski or an alpine ski, with improved driving behavior.
  • the essence of the present invention therefore lies in the fact that the longitudinal edge on the running side, which is at least on the inside during use, is reinforced.
  • a kind of “steel edge” is laid in the side cheek of the ski. It has been shown that such a construction gives the ski a higher grip when it is skated, without the sliding ability being impaired. Since the right and left skis can be interchanged at any time for normal use, the construction according to the invention is preferably carried out on both side cheeks of the ski. It is also important according to the invention that at least the side cheek that is inside during use is provided with a tread covering. This promotes the glide of the ski when "skating".
  • a specific embodiment is characterized in that a longitudinal edge reinforcement, in particular in the form of a longitudinal edge strip, is assigned to the side cheek, which is at least on the inside during use.
  • This longitudinal edge strip is preferably located between the lateral tread covering and the associated longitudinal edge of the lower tread covering.
  • the longitudinal guidance of the skis can be improved further in that longitudinal guide grooves are formed at least in sections near the two longitudinal edges of the lower tread.
  • the lower tread is made in a manner known per se from sintered or extruded polyethylene (PE), while the longitudinal edge strips, through which a reinforced edge construction is obtained, are made of hard but slippery material, such as PTFE, ABS or metal.
  • PE polyethylene
  • the side tread coverings assigned to the side cheeks are made of approximately the same hard elastic, in particular medium-hard plastic material as the lower tread cover, which is also said to be growable.
  • the longitudinal edge strips have a height of approximately 0.5 to 1.2 mm, in particular approximately 0.8 mm.
  • the height of the longitudinal edge strips can vary over their length. Starting from the center of the ski, it preferably decreases steadily or in steps in the forward and / or rearward direction.
  • the width of each longitudinal edge is approximately 1.0 to 10.0%, in particular 1.0 to 5.0% of the total width of the lower tread or the ski body.
  • the two aforementioned longitudinal grooves in the tread are located within the inner boundary of the longitudinal edge strips, albeit at a relatively short distance from them.
  • the tread and / or at least the tread covering associated with the use of the inner side cheek can have a recoil-effective, in particular scale-like surface structure.
  • the longitudinal guide grooves are arranged in sections in a front region comprising the ski tip and / or in a rear region of the ski comprising the ski end. This means that the longitudinal guide grooves are arranged either only in the front or only in the rear area of the ski or both in the front and in the rear ski area. This improves the smooth running and the guidance of the ski, especially at higher speeds.
  • the longitudinal guide grooves preferably each comprise a pair of grooves with individual grooves arranged in parallel. This arrangement of the grooves leads to a further improvement in the smooth running and the guidance of the ski.
  • the distance between the individual grooves of a pair of grooves is from 5 mm to 15 mm, in particular from 7 mm to 13 mm.
  • the length of the longitudinal guide grooves can be from 200 mm to 300 mm, in particular from 230 to 270 mm.
  • FIG. 1 shows the principle of a ski designed according to the invention, in particular skating skis, in cross section;
  • Figure 2 is a plan view of the lower tread surface of a ski with longitudinal guide grooves.
  • 3 shows a plan view of the lower tread surface of a ski with longitudinal guide grooves in pairs and
  • FIG. 4 shows the principle of a ski construction with a longitudinal guide groove formed in the lateral tread surface.
  • the ski body according to FIG. 1 is identified by the reference number 10.
  • the ski body 10 can be of classic construction, either with a wooden core, a foam core or a combination thereof.
  • the ski top surface 11 is also conventionally formed by a usually printed plastic film.
  • a tread 12 is arranged on the underside, which can consist of sintered or extruded polyethylene and is preferably waxable.
  • the two side cheeks are also provided with tread coverings 13, 14.
  • a longitudinal edge strip 15, 16 is arranged between the lateral tread coverings and the lower tread cover, which can consist of relatively hard but slidable, possibly also wax-absorbent material, such as PE, PTFE, ABS or metal. With regard to the dimensioning of these longitudinal edge strips, reference is made to the above statements.
  • the attached drawing also shows that two longitudinal grooves 17, 18 are also formed in the tread 12, each extending near the two longitudinal edges of the tread 12 and having an edge distance of between about 1.0 and 13.0 mm.
  • the side tread coverings 13, 14 consist of medium-hard plastic material, preferably also sintered PE, so that they are waxable.
  • the ski described is therefore characterized by a reinforced edge construction, the reinforcement being laid in the region of the side cheeks. Accordingly, the construction described is particularly suitable for so-called "skating". It goes without saying that the principle of ski construction shown in FIG. 1 can not only be applied to cross-country skiing, but is also suitable for alpine skiing.
  • FIGS. 2 and 3 show a further exemplary embodiment of the ski construction according to the invention, which can be used both for cross-country skis and for alpine skis. As can be seen from FIGS.
  • the longitudinal guide grooves 17, 18 or longitudinal guide grooves do not extend over the entire length of the respective ski, but are limited to a specific area of the ski.
  • the longitudinal guide grooves 17, 18 are only provided in the front region 19 of the ski, which includes the ski tip 20. It is also possible to arrange the longitudinal guide grooves 17, 18 only in the rear area of the ski, which is not shown here.
  • a combination of these two exemplary embodiments is also possible, in which the longitudinal guide grooves 17, 18 are arranged in sections only in the front region 19 and in sections only in the rear region of the ski, in such a way that the longitudinal guide grooves 17, 18 are not continuous, but in the longitudinal direction of the ski an area is separated in which the tread surface is smooth.
  • the longitudinal guide grooves 17, 18 can each comprise a pair of grooves 21, 22.
  • Each pair of grooves 21, 22 consists of two parallel grooves 2 LA, 21B, 22A, 22B, each of which extends near the two longitudinal edges of the tread 12.
  • the two pairs of grooves 21, 22 are each arranged on one side of the ski center line, the distance between the two individual grooves 21A, 21B, 22A, 22B of each pair of grooves 21, 22 being smaller in the present example than the distance between the individual grooves 21B arranged on the inside , 22B of the two pairs of grooves 21, 22.
  • the individual grooves 21B, 22B arranged on the inside can also be provided at a smaller distance from one another.
  • the distance between the individual grooves 21A, 21B, 22A, 22B of each pair of grooves 21, 22 is 5 to 15 mm, in particular 7 to 13 mm. In a particularly preferred form, the distance is 10 mm in each case.
  • the two groove pairs 21, 22 both only in the front section 19 or only in the rear section of the ski, and also in the front and can be arranged in the rear section of the ski.
  • the length of the longitudinal guide grooves 17, 18 is 200 to 300 mm, in particular 230 to 270 mm and is to be selected accordingly depending on the respective ski length. In a particularly preferred embodiment, the length is in each case 260 mm, the distance between the front end of the longitudinal guide grooves 17, 18, that is to say from the ski tip 20, as viewed in the direction of travel, being approximately 100 mm.
  • the distance between the longitudinal guide grooves 17, 18 according to FIG. 2 is approximately 53 mm, although other distances can also be selected.
  • the distance between the individual grooves 21B, 22B shown on the inside in FIG. 3 is approximately 40 mm and the distance between the individual grooves 21A, 22A arranged on the outside is approximately 60 mm.
  • the groove depth is 0.5 mm and the groove width is approximately 2.65 mm.
  • the groove width is approx. 2.65 mm, whereby the side groove walls are made with a radius of R 2.0.
  • FIG. 4 shows a further exemplary embodiment of the invention, which can be implemented both with cross-country skis and with alpine skis.
  • a further longitudinal guide groove 23 is formed at least in sections. This further longitudinal guide groove 23 is formed near the edge which delimits the lower tread surface 12 in the longitudinal direction of the ski.
  • the further longitudinal guide groove 23 can be arranged in the lower third of the side cheek. It is thereby achieved that in the case of cross-country skiing during “skating” and in the case of alpine skiing during “carving”, the further longitudinal guide groove 23 is pressed into the snow surface and can therefore perform a guiding function.
  • the further longitudinal guide groove 23 can, like the longitudinal guide grooves 17, 18 according to FIGS. 2, 3, be arranged in sections only in the front region 19 and / or in a rear region of the ski that surrounds the ski end.
  • the dimensions of the others Longitudinal guide groove 23 in the side cheek correspond to the dimensions given above in connection with the longitudinal guide grooves 17, 18 in the lower tread surface 12.
  • the longitudinal guide groove 23 shown in FIG. 4 in the tread surface 13 of the inner side cheek can be combined with the ski construction shown in FIG. 3 such that two groove pairs 21, 22 are formed in the lower tread surface 12 and the further longitudinal guide groove 23 are formed in the lateral tread surface 13.
  • the longitudinal guide grooves 17, 18 (FIG. 2) provided in sections in the lower tread surface 12 lead to an improvement in the ski guidance and smooth running of the ski, in particular at higher speeds.
  • a further improvement of these properties is achieved by designing the two longitudinal guide grooves 17, 18 as double grooves or as groove pairs 21, 22 (FIG. 4).
  • the tread surface 13 of the side cheek of the ski body 10 that is inside during use has, at least in sections, a further longitudinal guide groove 23
  • this further longitudinal guide groove 23 can be formed on both sides.
