Some embodiments disclosed herein provide an apparatus for joining two skis to form a splitboard. The apparatus can comprise a first attachment portion configured to attach to a first ski and a second attachment portion configured to attach to a second ski. The first attachment portion and the second attachment portion can be configured to engage to prevent splitboard skis from moving up and down relative to each other, from moving apart in a direction perpendicular to a seam of the splitboard, from sliding relative to each other in a direction parallel to the seam, and from rotating about the seam of the splitboard.

The present disclosure relates to splitboard bindings. The splitboard bindings can be used to change a splitboard between a snowboard for riding downhill in a ride mode and touring skis for climbing up a hill in a tour mode. The bindings can have a first interface and a second interface configured to engage and disengage. The interfaces can be configured such that a binding has large clearances for easy transitions. The first interface can be configured with a locking mechanism. The second interface can be configured to remove large clearances between the first interface and second interface, when the locking mechanism of the first interface is engaged with the second interface, allowing the first interface to attach tightly to the second interface and splitboard to improve the ride of the splitboard.

The invention refers to a folding ski for sporting or military purposes. The technical problem is how to conceive a functional ski without a retaining projection with a latching mechanism arranged at the front end of the ski front section, which projection is used to fasten a connecting platform in the folded state of the ski. The folding ski of the invention includes a ski front section, a ski rear section, a folding connection that inseparably connects the rear end of the ski front section with the front end of the ski rear section, a connecting platform that is intended to stiffen the folding connection and is pivotal around its axis of rotation a that extends perpendicularly to the upper surface of the ski, wherein the connecting platform is directly pivotally connected with the ski front or rear section.

A collapsible ski device, having: a first forward ski member having a bottom surface, a tip and a rear end; a second middle ski member having a bottom surface, a forward end and a rear end; and a third rear ski member having a bottom surface, a forward end and a tail. The forward end of the second middle ski member is pivotably coupled to the rear end of the first forward ski member by a first hinge mechanism. The first hinge mechanism has a flexible component attached at a first location to a first attachment surface on the first forward ski member and attached at a second location to a second attachment surface on the second middle ski member. The rear end of the second middle ski member is pivotably coupled to the forward end of the third rear ski member by a second hinge mechanism. The second hinge mechanism has a flexible component attached at a first location to a third attachment surface on the second middle ski member and attached at a second location to a fourth attachment surface on the third rear ski member.

A splitboard fastening system is disclosed herein. The splitboard fastening system comprises a crossbar comprising a shear bushing interface and a hook, an eccentric post coupled to a lever and configured to engage an inside edge of the hook in response to rotation of the lever, and a shear bushing configured to engage the shear bushing interface, wherein the crossbar is configured to be coupled to a first splitboard ski, and wherein the eccentric post and the shear bushing are configured to be independently coupled to a second splitboard ski.

One aspect of this disclosure is a sliding apparatus. In some aspects, the sliding apparatus may comprise an elongated body containing magnets. The elongated body may comprise a toe end, a tail end, a top surface, and a slide surface. In one aspect, the magnets may be located between the toe and tail ends of the elongated body, spaced apart from one another in the elongated body, and polarized to define top poles oriented toward the top surface of the elongated body and bottom poles oriented toward the slide surface of the elongated body. For example, the magnets may be arranged so the bottom poles have alternating polarities in a direction relative to the elongated body. Related apparatus and systems also are disclosed.

A ski having vents for venting snow from beneath the ski to a location above the ski and a modified keel that provides for greater and easier directional control over the ski relative to a conventional ski.
