    • The present invention provides for an anti-reverse sliding motion mechanism which comprises a pair of carriers (1) having a plurality of movable sliding plates (13) disposed therein. As each carrier (1) carrying the plurality of sliding plates (13) subject to a thrust in opposite direction, the sliding plates (13) extend and move to be in perpendicular to the carrier (1), thereby producing an anti-thrust resistance force which serves as a opposite force for moving forward. When the carrier (1) is subject to a forward pushing force, the anti-reverse sliding plates move to present a horizontal smooth surface which serves as a sliding surface. By the alternating action of the pair of carriers, a forward driving force is obtained as a result of the combination of anti-reverse and sliding actions.
    • 本发明提供了一种防反转滑动机构,其包括一对具有设置在其中的多个可动滑板(13)的托架(1)。 当承载多个滑动板(13)的每个承载件(1)承受相反方向的推力时,滑动板(13)延伸并移动成与载体(1)垂直,从而产生抗推力 作为向前移动的相反力的力。 当载体(1)受到向前推力时,防反转滑板移动以呈现用作滑动表面的水平光滑表面。 通过一对载体的交替作用,作为反向和反向滑动动作的组合的结果,获得正向驱动力。

    • The invention relates to a cross-country ski for classic cross-country skiing, including a gliding phase and a kicking phase. The ski comprises a common, continuous lower surface having a front and a rear glide zone and a central grip zone, the ski being formed with a central upward bent camber, which exerts a camber force against depression of the camber, such that in the gliding phase the ski is able to bear the weight of a skier while maintaining the central grip zone spaced from an underlying snow surface, whereas in the kicking phase, when the skier is exerting a kicking force towards the ski, the camber force is overcome and the grip zone is pressed towards the underlying snow surface. The ski additionally comprising a front part, a rear part and a camber regulating mechanism, said front part and said rear part being joined by an intermediate low flexural resistance portion of the ski having a reduced flexural resistance in comparison to adjacent portions of the ski, wherein the camber regulating mechanism has a high camber state and a low camber state where said high camber state is a state when the camber is maximally curved upwards and the grip zone is not in contact with the under¬ lying snow surface, whereas the low camber state is a state when the camber is low and the grip zone is in contact with the underlying snow surface. The camber regulating mechanism is bridging over the low flexural resistance portion and interconnecting the front and the rear parts and is designed such that it, at least in the high camber state, contributes to the overall camber force acting against depression of the camber and such that the camber force from the camber regulating mechanism is lower at the low camber state than at the high camber state or at a dead center position between the high camber state and the low camber state.
