Definitions

• the invention belongs to the field of sport articles, namely to skis, and concretely refers to a collapsible ski.
• the purpose of the invention is to create a ski, which shall consist of parts, which shall be simply assembled in situ without any tools, which could on the one hand simplify storage and transporting and on the other hand to simplify also technology of manufacturing of each particular part, when compared with manufacturing of classic one-part ski, wherein all components of the ski would have to be permanently interconnected both during the use and also in collapsed position, and none of constituent parts shall not protrude outside of the length of both parts of such ski, and wherein the concept of the ski shall provide to each average user all benefits like classic skis, in particular an uniform bending curve and correspondingly distribution of loads along ski edges.
• a collapsible ski is disclosed in SI 24358 A and WO 2014189472, to which the applicant In this application wishes to rely by reference, wherein such ski in its assembled i.e. functional state comprises a front area with a tip, which is smoothly bent away from the ground, a rear area with either at least approximately flat or smoothly bent away from the ground, as well as a central area, which is foreseen form mounting of a ski binding, which consists of a front part and a rear part and is mounted on the upper surface, which is faced away from the ground.
• the opposite sliding surface is during the use faced towards the ground and is furnished with ski edges, which extend at least along the majority of the ski length.
• Such ski consists of a front part and a rear part, which are interconnected and can be pivoted around the geometric axis, which extends parallel with said sliding surface. Moreover, said parts can be in their aligned position optionally immobilized by means of a platform, on which the front part and a rear part of a ski binding, which is foreseen for attachment of a ski shoe, are mounted. Moreover, when said front part and said rear part are aligned, and when being immobilized by means of a platform, said platform is rotatable around a geometric axis, which extends throughout the pivoting area between said parts and is perpendicular with respect to said sliding surface.
• said platform with mounted parts of a ski binding is adjusted to cooperate with each of said parts of the ski.
• said parts can be pivoted relative to each other, so that the ski in disassembled state can be stored, e.g. in rucksack, however, the platform is separated from said part, so that during the use e.g. in alpinism, or during military activities, it can be easily forgotten or lost or the like.
• the purpose of the invention is also providing a possibility of assembling parts, which are manufactured separately and can be standardized, both in view of semi products as well as finalized ski as a whole.
• a collapsible ski is also disclosed in US 4,405, 150.
• Such ski in its functional state ad when it is ready to use like each functional ski, comprises a front area with a tip, which is smoothly bent away from the ground, a rear area with either at least approximately flat or smoothly bent away from the ground, as well as a central area, which is foreseen form mounting of a ski binding.
• a surface, which is faced towards the ground, is furnished with a sliding surface, the lateral edges of which are equipped with ski edges serving for guiding of a ski when being turned on a hard ground.
• Such ski consists of at least three parts, which can be connected with each other in a detachable manner, namely of a front part and a rear part, which can be interconnected in a detachable manner, as well as of a top part, which is pivotally interconnected with said rear part and can be placed over at least a portion of said front part and then in such position of overlapping said parts fixed.
• Said top part is conceived as an U-profile and is adjusted to cooperate with two ribs, which are arranged on the top surface of said front part and said rear part at least in the central area in the area of cooperation of said parts and which protrude apart from the ground.

• Such local increasing of stiffness leads to essential changing of bending properties of the ski as a whole, since its bending capability in the front area and in the rear area is essentially higher than in the central area.
• the described concept of the top part in the form of U-profile does not allow mounting of rails for quickly mounting of ski binding. Adapting of the top part for such purpose would namely lead to additional essential increasing of height, weight and stiffness of the ski.
• the invention refers to a collapsible ski, which in its assembled i.e. functional state comprises a front area with a tip, which is smoothly bent in a direction apart from the ground, a rear area with a tail, which is either at least approximately flat or smoothly bent away from the ground, as well as a central area, which is foreseen form mounting of a ski binding, which consists of a front assembly and a rear assembly and is suitable for attachment of each ski shoe onto a top surface of the ski, which is during the use faced apart from the ground.
• the opposite surface of the ski, which is during the use faced towards the ground is furnished with ski edges, which extend along at least the majority of the ski length.
