Collapsible ski

A collapsible ski, comprising:

• in its assembled, functional state:
• a front part of the collapsible ski comprising a front portion with a tip slightly bent away from a ground surface;
• a rear part of the collapsible ski comprising a rear portion with a tail;
• a central region of the collapsible ski comprising a connecting platform, wherein the connecting platform is adapted for mounting a ski binding comprising a front part and a rear part onto a top surface of the collapsible ski, wherein the ski binding is suitable for attaching a ski shoe onto a top surface of the ski, the top surface during use of the collapsible ski being faced away from the ground surface;
• an opposite sliding surface, including two ski edges, wherein the opposite sliding surface is faced towards the ground surface during the use of the ski;
• wherein the collapsible ski, when assembled, includes the front part of the collapsible ski and the rear part of the collapsible ski mutually interconnected pivotally around a transversal geometrical axis extending parallel to the sliding surface,
• wherein the front part of the ski is, in the area of engagement with the connecting platform, furnished with a front part indentation,
• wherein the rear part of the ski is, in the area of engagement with the connecting platform, furnished with a rear part indentation,
• wherein the connecting platform is adapted to rest within the area of the front part and rear part indentations, and
• wherein the connecting platform is, on each of its terminal portions, which protrude apart from each other, furnished with a convex circular surface having a pre-determined radius of curvature, wherein each convex circular surface includes a protrusion,
• wherein the front part indentation terminates with a concave circular surface, wherein a radius of curvature of the front part indentation concave circular surface is adjusted to the radius of curvature on the corresponding terminal portion of the connecting platform, wherein the front part indentation includes is furnished with a groove, which is adapted to cooperate with the protrusion on the corresponding terminal portion of the connecting platform, and
• wherein the rear part indentation terminates with a concave circular surface, wherein a radius of curvature of the rear part indentation concave circular surface is adjusted to a radius of curvature on the corresponding terminal portion of the connecting platform, wherein the rear part indentation includes a groove, which is adapted to cooperate with the protrusion on the corresponding terminal portion of the connecting platform.

• wherein the front part of the collapsible ski is, in the area of engagement with the connecting platform, furnished with a front part guiding protrusion located on an essentially flat top surface of the collapsible ski;
• wherein the rear part of the collapsible ski is, in the area of engagement with the connecting platform, furnished with a rear part guiding protrusion located on the essentially flat top surface of the collapsible ski,
• wherein the connecting platform is adapted to rest within the area of the front part and rear part guiding protrusions;
• wherein the connecting platform is, on each of its front and rear terminal portions which protrude apart from each other, furnished with a convex circular surface having a pre-determined radius of curvature, wherein each of the front and rear convex circular surfaces include a protrusion,
• wherein the front part guiding protrusion includes a concave circular surface, wherein a radius of curvature of the front part guiding protrusion is adjusted to the radius of curvature on the front convex circular surface of the connecting platform, wherein the front part guiding protrusion further includes a groove adapted to engage with the front convex circular surface protrusion, and
• wherein the rear part guiding protrusion includes a concave circular surface, wherein a radius of curvature of the rear part guiding protrusion is adjusted to a radius of curvature on the rear convex circular surface of the connecting platform, wherein the rear part guiding protrusion further includes a groove adapted to engage with the rear convex circular surface protrusion.
