A skiing device having at least a pair of parallel, elongated, longitudinally extending runners is provided with a platform therebetween, and quadrilateral linkage arrangements extend between the runners and the platform independently while at least one link member extends between the runners. The quadrilateral linkage arrangements between the runners and the platform allow the ski to carve a turn in the slope of a hill with more ease since the two runners present separate control edges.
A linkage connecting two runners and a platform, includes three link members in a pentagonal configuration to effect a progressive shift of weight onto the uphill runner from the downhill runner during rotation of the runners about the long axis of the platform.
A combination ski and binding plate apparatus comprising a first and second mounting plate assembly for supporting mounting plates for boot bindings and for operably linking a pair of skis. The first and second mounting plate assemblies each comprise a four bar linkage assembly including a first inner bar and a first outer bar operably secured to a mounting plate. The first inner bar is pivotally secured to the first outer bar. A rear linkage assembly including a rear inner bar and a rear outer bar are operably secured to the mounting plate. The rear inner bar is pivotally secured to the rear outer bar. Both the front linkage assembly and rear linkage assembly are secured to both skis allowing the skis to pivot and move about a central pivot point allowing a downward pressure or force on either side of the mounting plate to be translated into an upward force on an opposite side of the plate providing an upward lifting force to a ski edge beneath the opposite side of the plate from which the downward or force is exerted on the plate resulting in a parallel synchronized motion with outside and inside edges of the skies always maintaining the same position relative to each other.
The present invention discloses a sports device for sliding on an underlying surface, in particular a winter sports device, having parallel skates having sliding surfaces, at least one connecting member running transversely with respect to, and jointedly interconnecting, the skates such that the sliding surfaces of the skates lie substantially parallel to each other, a standing plate and at least one swivelling lever for securement of the foot engaging device on each connecting member, wherein each swivelling lever is articulated jointedly on the connecting member by means of an offset axle member for producing an acentric swivelling axis, wherein on each connecting member (crossbar) there are arranged at least two swivelling levers symmetrically and eccentrically with respect to the longitudinal axis of the winter sports device on each side, and wherein the swivelling levers are arranged in plan view at least partially outside the eccentric swivelling axes, which represent the connection between connecting member (crossbar) and swivelling lever.
Alpine ski (1) having a sidecut (9) which has a radius smaller than 24 meters, wherein the front (10) and/or rear (18) ends have a cavity (11, 15) opening longitudinally at said end, the dimensions of the cavity (11, 15) allowing the deformation of said end when a transverse force is exerted at the front and/or rear contact lines so as to permit the inner and outer edges of the ski to move closer to one another.
A multi-edge snowboard includes multiple boards with attached bindings. A pivot mechanism that connects the bindings to the boards rotates each board, so that each board can provide an active edge that engages the snow during turning or stopping. The increase in the number of active edges relative to a conventional snowboard improves the performance of the multi-edge snowboard, while the binding structure retains the feel of a conventional snowboard.
