Definitions

• the present disclosure relates to snow-sport equipment and more specifically to a combination snowboard and downhill ski.
• downhill skiing has a long history of innovation and a great variety of ski designs have been developed over the years.
• Generally downhill skis are substantially flat axial planks with a binding used to couple with a ski boot.
• Each axial side of the individual skis has a sharpened metal edge that gives the skier the ability to turn and control his speed during downhill descent.
• the axial side of the individual skis have a parabolic sidecut, meaning the tip and tail of the ski are wider then the middle of the axial distance.
• the parabolic shape gives the skier more control over turning because the sidecut naturally encourages parabolic motion downhill as a skier applies pressure to the given edge.
• cross-country skiing and backcountry/ alpine trekking there are many solutions for cross-country skiing and backcountry/ alpine trekking.
• One common design feature for cross-country skiing and backcountry/ alpine trekking skis include a binding that holds the toe of the boot securely in place while allowing the heel of the boot to rise and fall in a rhythmic motion.
• the rhythmic motion facilitates gliding as opposed to a marching motion that is used when snowshoeing.
• snowboards are typically designed with substantially parabolic edges to facilitate turning.
• snowboards also typically employ bindings that semi-permanently hold the snowboarders boot to the board, forcing the rider to strap in and strap out of the bindings one or two feet when a rider wants to traverse flat or upward portions of the mountain or trail.
• unstrapping one foot from a snowboard and "skating" eliminates the advantage of having a large surface area under a rider's feet, causing the rider's feet to sink into the snow and requiring more effort.
• splitboards which allow use of a single device for more than one ski/ride style, have gained a somewhat recent popularity.
• a splitboard is a reconfigurable snowboard/ alpine- trekking ski combination designed with various clasps and multi-purpose binding configurations to allow a user to physically split a snowboard down its length into two skis, reconfigure the bindings, and use the skis for cross country skiing or backcountry trekking.
• splitboards do not have inside edges suitable for downhill skiing. Due to the lack of edges and a function-limiting straight inside edge, splitboard skis are unusable for downhill skiing.
• a combination ski-snowboard device interchangeably configured in one of: a ski configuration comprising two skis each with both an inside and outside edge and a ski binding mounting systems, and in a snowboard configuration having two outside edges and two binding mounting systems.
• Some embodiments involve a ski-snowboard combination device involving a first gliding board having and first edge having a substantially concave shape, a second gliding board having a first edge having a substantially concave shape, and a fastening device configured to reversibly affix the inside edge of the first gliding board to the inside edge of the second gliding board, thereby forming an opening with two convex sides.
• the ski-snowboard combination device comprises a ski binding mounting system coupled with each of the gliding boards and one half of a snowboard binding system, thereby allowing the ski-snowboard to be converted between ski and snowboard configurations.
• the ski binding mounting systems involve a bottom plate coupled with a gliding board, an aperture in the bottom plate, and a top plate having a disk disposed on the bottom-side surface of the top plate.
• the disk releasably couples with the aperture of the bottom plate and releases in the event of a threshold level of torque applied to the disk and a topside surface of the top plate is configured with a boot.
• the bottom plate includes a torque-sensitive release mechanism, a set screw accessible from the outside of the bottom plate in mechanical communication with the torque-sensitive release mechanism and configured for adjusting the threshold torque, an release setting gauge visible from the outside of the bottom plate for displaying a quantified representation of the threshold torque.
