Definitions
- This invention relates to improvements in skis and, in particular, to improvements which will increase the edge holding on a ski.
- Skis of various sizes and shapes are well known and specific skis can be designed to operate optimally under different conditions. Variations in the shape of a ski which appear somewhat minor can, when the ski is being used to the extreme of its performance, make a perceptible difference in that performance. If, for example, the ski is being used for racing, the difference may be of great importance.
- the object of the present invention is to provide a ski which increases the edge holding during turning and skiing transverse to a slope.
- a ski with a lower and an upper face having on an inner edge of the lower face a groove narrow relative to a width of the ski.
- the groove may be of the order of 2mm wide and 0.2 to 0.5 mm deep.
- the outer edge of the groove may be provided with a bevel.
- the ski can be conventional and its overall form of construction will not be described herein.
- a ski 10 is provided with an upper and a lower face 11.
- the upper face can be utilised for the fixing of a ski-boot 15 and the lower face 11 for contact with a surface, for example ground, snow, ice, dry ski-slope etc.
- a concave groove 13 is provided along an inner edge of the lower face 11 of the ski 10.
- the groove 13 extends approximately 10 to 15 cm forwardly beyond a toe of the ski-boot 15 and approximately 10 to 15 cm rearwardly of a heel of the ski-boot 15.
- the groove 13 may be of the order of 2 mm wide and 0.2 to 0.5 mm deep.
- a bevel 14 may be provided of, for example, between 0.5 degrees and 3 degrees and may run the length of the groove 13 or may, in fact, extend either the full length or over a substantial length of the ski 10.
- the ski of the present invention provides features for skiers of all calibres.
- the provision of the groove 13 and the adjacent edge increases the edge holding on the ski when turning or when skiing transverse to the slope, as it reduces the on-snow contact area and thus increases the downward pressure on the inside edge of the ski, which is the most critical part of the ski during such manoeuvres.
- the skier can maintain higher speed during turning and can also decrease the radius of the turn.
- the ski of the invention provides more consistent drive during turning and increased stability in changing conditions.
- the ski of the invention provides greater security than otherwise in hard packed snow, man-made snow and in icy conditions.
