  • Patent number: 5181894
    Abstract: A ski-practicing device includes front and rear base members and two longitudinal members disposed in parallel therebetween. A sliding pedal is slidably mounted on each longitudinal member to provide a foot rest. A sliding member is slidably mounted in each longitudinal member. A stick assembly is pivotally attached to each sliding member by a pivotal plate, thereby allowing the stick assembly to be slidable relative to the longitudinal member via the sliding member. Such an arrangement also allows an outward pivotal movement of the stick assembly and the pivotal plate relative to the sliding member, and allows forward and rearward pivotal movement of the stick assembly relative to the pivotal plate.
