Device and methods for a ski assembly system and snowboard assembly system having a ski or snowboard with a centerline axis, a perpendicular axis, and a ski suspension system. The ski or snowboard suspension system has a suspension platform with two or more struts rotatably coupled with the suspension platform and at least one of a front mount assembly and a rear mount assembly.

A ski for use on ice or snow is disclosed. The ski includes a ski body having a tip portion, a tail portion, and a longitudinal running length extending between the tip portion and the tail portion and a substantially flat bottom surface for sliding on snow or ice. The ski also includes a suspension system comprised of a substantially rigid support structure secured to the longitudinally central region of the said ski body at two attachment locations separated by a distance of at least 5 inches along the longitudinal axis of the ski body, and at least one resilient element configured to exert an opposing force between the support structure and the ski body in the area between the two attachment locations.

A mounting plate and mounting plate system for a ski comprising: a bottom surface configured to be placed against a ski; an upward directed left and right side edge along the outer sides of the mounting plate, where the edges have laterally opposed undercuts that are configured to hold a ski binding with complementary cuts fastened to the mounting plate in the vertical direction; a longitudinal groove, configured to hold a first interchangeable rail fixed in the lateral direction and the longitudinal direction, and a second interchangeable rail which can be interchanged with the first rail, fixed in a lateral direction but movable in the longitudinal direction.

A support plate for a binding for a gliding board that includes the following: a chassis to be fixed on an upper surface of the gliding board; a damping plate intended to be at least partially interposed between a lower surface of the chassis and the upper surface of the gliding board. The support plate includes a wedge that is less compressible than the damping plate, movable between a hardness configuration, suitable for transmitting a vertical force from the chassis to the upper surface of a gliding board, and inhibiting, at least partially, the compression of the damping plate and between a flexibility configuration, suitable for the force to be retransmitted from the chassis to the upper surface of a gliding board, mainly via the damping plate.

Device and methods for a ski assembly system and snowboard assembly system having a ski or snowboard with a centerline axis, a perpendicular axis, and a ski suspension system. The ski or snowboard suspension system has a suspension platform with two or more struts rotatably coupled with the suspension platform and at least one of a front mount assembly and a rear mount assembly.

A ski binding moving mechanism (1) comprising:a ski binding (2a) configured to be fastened in the vertical and lateral direction on a ski, and further configured to be movable in the longitudinal direction relative to the ski;a rod (5) with two or more pushing elements (51a, 51b, . . . ), the rod (5) being fastened to the ski binding (2a); anda rotatable element (32), configured to be fastened fixedly relative to the ski in the longitudinal direction of the ski, the rotatable element (32) being rotatable relative to the ski (6), wherein the rotatable element (32) comprises:a first and a second rotating pin (321, 322) configured to rotate with the rotatable element (32), and cooperate with the pushing elements (51a, 51b, . . . ), whereinthe rotatable element (32) is configured to be rotated at least one revolution and move the rod (5) and the binding (2a) in the same longitudinal direction throughout the revolution.

A mounting plate and mounting plate system for a ski comprising: a bottom surface configured to be placed against a ski; an upward directed left and right side edge along the outer sides of the mounting plate, where the edges have laterally opposed undercuts that are configured to hold a ski binding with complementary cuts fastened to the mounting plate in the vertical direction; a longitudinal groove, configured to hold a first interchangeable rail fixed in the lateral direction and the longitudinal direction, and a second interchangeable rail which can be interchanged with the first rail, fixed in a lateral direction but movable in the longitudinal direction.

A system, method and apparatus for a digitally Controlled Variable Stiffness item of athletic equipment, such as a Ski, Snowboard, and Boots. A core of thermally responsive metal alloy, such as Nitinol is disposed within the athletic equipment. A thermal control module and controller permit the athlete to program the athletic equipment to a desired stiffness parameter. The controller may include an app operable via a mobile computing device in communication with the thermal control module.

The present invention relates to a mounting system for a binding, or a binding component (2; 4) on a cross-country ski, where a mounting plate (6) is arranged on the top surface of the ski and where the mounting plate (6) comprises longitudinal side edges having a profile (33) with undercuts for longitudinal positioning and attachment of the binding or binding component (2; 4) with the aid of a complementary profile (34) on the binding or binding component (2; 4). According to the invention, the mounting plate (6) comprises a longitudinal channel (21) that houses a longitudinal rail (5), where the upper side of the rail (5) comprises at least one locking device (20; 23), and where the underside of the binding or binding component (2; 4) comprises at least one complementary locking device.

A ski shoe harness includes a sole, a receiver, and a heel strap. The sole includes a binding mechanism adapted to engage a binding system of a ski. The sole and the receiver are attached and define a space to receive the front portion of a shoe. The heel strap, attached to the receiver, wraps around the rear portion of the shoe, interlocking the ski shoe harness with the shoe. Further, the heel strap includes an adjustment mechanism. Using the ski shoe harness of the present invention, non-ski shoes and boots of a various designs and sizes may be used to share and utilize skis having common cross-country binding systems.
