Definitions
- the invention relates to a pair of skis for alpine skiing, with asymmetrically tailored skis, each ski having a more curved side shape cutout on the outside than on the inside.
- the outer ski i.e. the ski on the outside of the curve
- the inner ski remains more or less unloaded.
- the shape of the inside of the respective outer ski is of primary importance for cornering.
- Various ski geometries have already been proposed in this connection to facilitate the initiation of turns, cf. e.g. the AT 387 147 B or the corresponding FR 2 559 673 A, where a specific, strong waist is proposed to facilitate archery, especially in fresh snow, which is also intended to merge into straight sections at the front and rear via kinks.
- a comparable ski with straight sections in the shovel area and in the end area and with a strong waist is further described in DE 41 12 950 AI.
- a different curvature of the side shape cutouts on the inside or outside of the ski is also disclosed for the purpose of adapting the skiing behavior to the desired operating conditions.
- the curvature on the inside of the ski should be stronger than that on the outside of the ski.
- ski geometries result, in which the outer sides of the skis have more curved side shape cutouts than the inner sides.
- this situation occurs when the skis of a pair of skis, in which the inside curvature of the skis is preferably stronger than the outside, are exchanged, so that instead of being particularly suitable for short turns, they are suitable for long giant slalom turns achieve.
- the known ski designs have in common that they are designed for a conventional skiing technique, in which in particular "on the inner edge” of the outer skis (or valley skis) is used, the shape or geometry of the Side shape cutout on this inside the suitability for shorter or longer turns, for an easier turn initiation etc. is obtained.
- a new skiing technique is the so-called “carving” technique, in which the skier tries to load both skis as evenly as possible when cornering; this new technology started with snowboarding, and similar to snowboarding, skiing with the carving technique takes a swing under the same load on both skis, i.e. cornering, simply initiated by "folding" the legs in the area of the knee joints, in which case the bow is to be driven both on the inner edge of the outer ski and on the outer edge of the inner ski.
- the known skis consistently lead to problems, since the arches given by the waists of the inner edge of the outer ski or the outer edge of the inner ski are not “parallel” to one another, but intersect one another. When cornering according to the carving technique, this means that the inner ski cannot be guided parallel to the outer ski, or only with difficulty. the skis cross over or the inner ski is pulled away from the outer ski, causing falls.
- the aim of the invention is to provide a pair of skis of the type mentioned at the beginning, which provides a remedy here and, due to its design, is particularly suitable for carving skiing technique.
- the pair of skis according to the invention of the type mentioned at the outset is characterized in that the waist on the outside of each ski is set back by a measure in the cm range compared to that on the inside, whereby when cornering, in which the two skis are at a distance in dm Area from each other with which the outer ski is set back in the direction of travel relative to the inner ski, the waists of the outside of the inner ski and the inside of the outer ski describe at least approximately concentric arches.
- both skis succeed in parallel when cornering with a relatively wide ski guidance, even when the inner ski is loaded when driving according to the carving technique to hold each other so that blending or the like is avoided.
- the centers of curvature of the waists of the inside of the outer ski and the outside of the inner ski are centered -to the center-ski distance of approx. 30 cm to 50 cm, in particular approx. 40 cm to 45 cm, and when the outer ski is set back from the inner ski of approx. 10 cm to 25 cm, in particular approx. 15 cm to 20 cm, essentially collapse.
- the difference in the radii of curvature can be, for example, only 2 or less than 10%.
- the radius of curvature of a pair of skis with a length of approx. 200 cm on the inside of the skis about 28 m each and on the outside about 26 m each; with shorter skis, for example with a length of 170 cm, the corresponding radii of curvature can be 26 m or 24 m.
- the preferably provided outward displacement of the waist on the outside of each ski compared to the waist on the inside (or in comparison to a symmetrical ski design) is, for example, in the range from approximately 1 mm to (preferably) 1.5 mm for shorter ski lengths (about 170 cm) and at about 2 mm to 4 mm, preferably 2.5 mm, with longer ski lengths (about 200 cm).
- a version of the ski geometry has also proven to be favorable, according to which the waist on the outside of each ski in the area of the ski end ends further back than the waist on the inside of the ski.
- the outside waist of each ski thus ends - despite the greater curvature - behind the waist on the inside of the ski, viewed in the direction of travel.
- the amount of recessing of the outside waist in the ski end area is approximately 3 cm.
- the waist can transition from the concave curvature to the convex curvature in the blade area in a conventional manner. This transition, as well as the transition into the straight part of the outside of the ski and from this into the convex shovel part on the outside of each ski, can also be achieved by means of curved pieces, so-called splines.
- Fig.l in a schematic plan view of a pair of skis, and not to scale, but greatly exaggerated in terms of the shape of the outside waist of the inner ski, so as to better illustrate the effect to be achieved according to the invention
- FIG. 2 shows a schematic plan view, on a larger scale, of a comparable, approximately scale-drawn pair of skis
- FIG. 3 shows a detail in a top view, on an enlarged scale, compared to FIG. 2, details regarding the displacements of the outside waist of each ski compared to the inside waist.
- a pair of skis is shown schematically in plan view when cornering, the outer ski in the curve, the outer ski 1, being set back in the direction of travel 3 relative to the inner ski in the curve, the inner ski 2.
- the two skis 1, 2 are fitted, whereby in the left ski in Fig.l, the outer ski 1, a conventional, symmetrical waist is shown, ie the side shape cutout 14 on the outside (ie the side facing away from the other ski 2) and the Side shape cutout 15 on the inside of the ski 1 have the same curvature.
- the Inner ski 2 illustrates an outside side shape cutout 24 ′ with the same curvature as the side shape cutout 25 on the inside with a dash-dotted line.
- the inside waist of the outer ski 1 or the outside waist of the inner ski 2 defines arches 16 and 26 'which are not concentric, cf. also intersect the centers of curvature M or M ', but at a distance in front of the skis 1, 2.
- Relevant for this is, in particular, the fact that, when cornering, the inner ski 2 is usually guided in front of the outer ski 1 in the direction of travel, as is also shown in FIG. 1.
- the center-to-center distance D of the two skis 1, 2 must also be taken into account, which is relatively large, especially in the new carving skiing technique, and is to be set in the range from 30 cm to 50 cm, approximately 40 cm to 45 cm .
- this ski distance D could be compensated for by a more curved side shape cutout 14 or 24 'on the respective outside of the ski compared to the inside side shape cutout 15 or 25, i.e. by means of correspondingly large radii of curvature R for the curvature of the inside side shape cutouts 15 or 25 im
- the center of curvature (see M and M' in FIG. 1) is still apart due to the longitudinal offset of the skis 1, 2; so that intersecting arches 16 and 26 'are obtained which are traversed with the inside of the outer ski 1 and the outside of the inner ski 2.
- the waist ie the concavely curved side shape cutout 24, on the outside of each ski 1, 2 compared to the waistline, that is to say the concavely curved side shape cutout 15 or 25, on the inside of the respective ski 1, 2 towards the rear offset, which, in conjunction with the smaller radius of curvature r for the outside waist, enables concentric arches 16, 26 to be achieved at least approximately.
- the waist on the outside of the ski is preferably also moved outwards, this outward displacement at the beginning of the waist, adjacent to the ski shovel, is strongest and this outward displacement towards the rear end of the ski runs to zero.
- This is greatly exaggerated in Fig.l for the right ski, the inner ski 2, illustrated, this graphic exaggeration is also related to the fact that the radii of curvature R, r are drawn briefly in relation to the ski length.
- the two skis 1, 2 are drawn approximately to scale in the case of a comparable cornering (see arcs 16 and 26, respectively), the longitudinal offset of the respective outside waist of the skis 1, 2 compared to the inside waist is adjacent in the region of the respective ski shovel 7, but especially in the area of the ski ends 8 clearly visible.
- these geometric relationships result more clearly from the plan view according to FIG. 3 drawn on a larger scale.
- the concavely curved side shape cutout 25 begins on the inside of the ski 2 at a point 9 which lies further forward, viewed in the longitudinal direction of the ski, than the point 10 at the start of the concave curved side shape cutout 24 on the Outside of the ski 2.
- This offset in the longitudinal direction of the ski is indicated in Figure 3 with the dimension X.
- the outside waist ie the curve of the outside side shape cutout 24, in comparison to a symmetrical design shown in dashed lines, thus in comparison to a waist such as that on the (left) inside of the ski 2 would correspond to a dimension Y offset to the outside, namely in the front ski section, adjacent to the ski shovel 7.
- This outward displacement of the outside waist runs towards the end of the ski towards zero, but at the end of the ski 8 there is still a length -Displacement of the outside waist (outside side cutout 24) to the rear by a dimension x, compared to the waist on the inside of the ski 2.
- the dimension x is preferably smaller than the dimension X, as can be seen from the illustration in FIG. It is also possible that the waist (side shape cutout 24) on the outside of each ski 1, 2 extends to the extreme end of the ski.
- a straight section 11 is provided on the outside of the ski 2 following the concavely curved side shape cutout 24 (or 14 in the case of the ski 1), which is preferably parallel to the longitudinal axis of the ski 2 runs, possibly also diverging forwards relative to the longitudinal axis of the ski, so as to avoid a plow-like geometry with a corresponding braking effect in this area that plows backwards.
- the limiting curves are made up of individual smoothly merging curve pieces, so-called splines, educated.
- the longitudinal offset of the waists at the front (dimension X) or at the rear (dimension x) can be the same throughout, for example 4 cm or 3 cm, the outward displacement of the outside waist in the front ski area (dimension Y) changes with the ski length;
- the dimension Y for ski lengths in the range of 200 cm is approximately 2.5 mm, possibly 2.2 mm to 2.3 mm (2.5 mm is considered the preferred maximum, although dislocations of up to 4 mm are also possible); in the case of shorter ski lengths, approximately 170 cm, the dimension Y is preferably approximately 1.5 mm, in some circumstances even only approximately 1 mm.
- the radii of curvature R or r differ depending on the ski length and can be 28 m or 26 m for ski lengths of approximately 200/205 cm, for example 26 m / 24 for ski lengths of 170 cm.
- the largest ski width in the area of the shovel 7 can, as studies have shown, be about 10 cm for the ski geometry described, specifically with a ski length of about 200 cm, whereas the greatest width at the ski end 8 is about 8 cm for this ski length is.
- the width at the narrowest, approximately central point of the ski for a ski length of 200 cm is approximately 6 cm.
- the corresponding values can be provided as follows: maximum width on the ski shovel 7: 8.8 cm; greatest width at the end of the ski: 7.6 cm; smallest width (ski center): 6 cm.
- the skis 1, 2 can be manufactured according to conventional construction methods, for example according to the sandwich construction or according to the shell construction.
