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.

The invention relates to a folding ski having an articulated connection. The technical problem is to configure a folding ski structure that will act as a classic ski, which means that the assembled structure of the folding ski will act as a uniform support. The folding ski of the invention comprises a ski front section, a ski rear section, an articulated connection that inseparably connects the ski front section with the rear section, a connecting plate intended to strengthen the articulated connection of the ski, the connecting plate comprising a front and rear base plate and a bridging plate, wherein a plurality of ribs and/or grooves in the shape of a circular arc are formed on the upper side of the front base plate and the rear base plate and a plurality of grooves and/or ribs are formed on the bottom side of the bridging plate so that each pair of a rib and a groove forms a positive lock connection that transfers longitudinal shear forces, and at least a part of the ribs is formed with at least one flap and the corresponding groove is formed with a notch which receives a flap so as to form a positive lock connection which also transfers vertical forces.

An improved highback adjustment system for a splitboard boot binding. A captive strut is mounted on the spine of the highback, the strut having a forward lean adjustor block such that rotation or sliding of the block lengthens or shortens the strut. The combination provides a broadly adjustable range of forward lean bias in small increments and the block is readily disengaged and stowed on the highback when not needed. Advantageously, the mechanism that can be operated and adjusted without tools, even with gloved hands, a significant benefit in winter conditions, and does not jam with snow. Methods of use of the improved forward lean adjustor and highback are also disclosed.

A flat board as a base plate of a binding for splitboards with holders for the bindings' fixation on skis that are joined together to form a snowboard that has a circular slit (or opening) formed in a central part of the board. The circular slit is equipped with a perimeter recess for removable fixation of a contact ring which is, on its inner perimeter, equipped with two pairs of opposed dents (or indentations) that are designed for connection with a holder. The contact ring is also modified between the dents (or indentations) for insertion of end pins of a locking eccentric. The locking eccentric is formed by an axial shaft with end pins protruding from end hubs formed at both ends of the axial shaft.

A binding system includes a base portion shaped to receive a boot. The base portion has first and second opposite facing surfaces. The binding system also includes a first interface having first and second surfaces. The first interface includes two separable interface portions, with each of the two interface portions having first and second opposite facing surfaces and including at least one coupling element disposed over at least the second surface of the interface portion. The at least one coupling element includes a body segment proximate to the second surface of the interface portion and a blocking head segment distal to the second surface of the interface portion. The body segment has a first width with respect to a longitudinal axis of the body segment and the blocking head section having a second, greater width than the first width.

Splitboard binding systems including a binding that may be attached to either a left or right gliding board in a ski mode or to both gliding boards in a snowboard mode. The binding includes left and right bottom rails attached to the bottom surface of a base plate, which define channels for slidable attachment to “pucks” disposed on the gliding board in snowboard mode. Each rail has a circular bore at a forward end for attachment to a counterpart pivot pin on a ski mode toe bracket in a ski mode by a sideways movement. A securing lever is disposed on an upper surface of the toe bracket. When the securing lever is rotated into a securing position, an end of the securing lever prevents removal of the pivot pin from the rail bore. Rotating the securing lever to a removal position allows the binding to be removed.

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.

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.
