Abrégé

The present invention relates to a ski (1) for ski touring or a grip part (10) attachable to a ski for ski touring or cross-country skiing, which ski (1) is comprised of an elongated, beam-like structure comprising at least side walls (2), an upper surface (3) and a base (4). Over at least a part of the distance to the middle part (42) of the base, on the surface layer (40) of the base (4), are formed lamellas (401) by means of slits (400) transverse to the longitudinal direction (L) of the ski (1), tilted backwards with respect to the normal (N) of the base (4) and the longitudinal direction (L) of the ski (1), each lamella (401) comprising a foot (405), two sides (402, 403), and one side (404) parallel with the base (4), wherein in the gliding phase the base side (404) is arranged parallel with the base (4), defining an substantially flat gliding surface. At the push-off phase, when a backwards pushing force is applied to the ski (1), at least some of the lamellas (401) deform in the direction of the normal (N) of the base (4), generally retaining their shape starting from the foot (405), forming a contact surface of increased friction. The invention also relates to a corresponding method for treating the ski or grip part.

Abrégé

The present invention relates to a ski (1) for cross-country skiing, which ski (1) is comprised of an elongated, beam-like structure comprising at least side walls (2), an upper surface (3) and a base (4), the ski (1) being formed to be cambered, wherein the base (4) is made to curve upwards over the length of the ski, the front (41) and rear (43) parts of the base are in contact with the ground, but the middle part (42) of the base is detached from the ground when the ski (1) is placed, with its base (4) against the ground, unweighted on an even horizontal ground. Over at least a part of the distance to the middle part (42) of the base, on the surface layer (40) of the base (4), are formed lamellas (401) by means of slits (400) transverse to the longitudinal direction (L) of the ski (1), tilted backwards with respect to the normal (N) of the base (4) and the longitudinal direction (L) of the ski (1), the lamellas comprising two sides (402, 403), and one side (404) parallel with the base (4), the lamella (401) extending from the surface layer (40) of the base (4) to the inner layer (45), to which the lamella (401) is connected. The invention also relates to a corresponding ski for freestyle cross-country skiing, and a method for treating the ski.
