Abstract: Systems, apparatus and methods for gliding on a surface with improved mobility are described. According to various embodiments, boards are provided which are configured to overlap. This innovative overlapping ability helps allow for versatile stance configuration and ensures that collision between the boards occurs between a base and an edge. This type of collision will generally result in a sliding action, allowing one board to ride up onto the top of the edge of the other board. This type of interaction reduces damage to the boards and improves riding experience. Boards with equal height nose and tail shovels are more likely to collide edge-to-edge in a disruptive manner. Other embodiments are described and claimed.

Abstract: Skibobs are disclosed having features for conveying the skibob with rider on a moving chairlift while the rider remains mounted on the seat of the skibob. The frame and suspension are configured for elevating the underside of the skibob seat above the level of the chairlift bench during loading, so that the chairlift bench, while moving forward from behind the rider, can pick up the skibob, rider and all, and carry the mounted rider up the ski slope without falling. As the undercarriage of the skibob is lifted off the snow, the rider is deposited on the chairlift bench so that the seat of the skibob is secured in place by the weight of the rider on the seat.

A pair of transverse support portions are provided. The first upper and second lower contact surface regions also include a plurality of complementary engagement formations to provide a positive engagement and lateral indexing between the elongate blade support portions and the transverse support portions. The elongate blade support portions and the transverse support portions are maintained in engagement by a plurality of coupling members.

Abstract: A steering mechanism for a recreational vehicle includes a foot support and a steering device connected to the foot support, the steering device being moved by a motion of the foot support. A recreational vehicle is also disclosed that includes a front portion, a body connected to the front portion, a track mechanism disposed in the body, a steering mechanism disposed in the front portion, and a foot support disposed between the front portion and the body, the steering mechanism being steered by a motion of the foot support. A method of steering the recreational vehicle is also disclosed.

Abstract: A skateboard/ski combination wherein the four wheels of a traditional skateboard have been removed, while the skateboard trucks remain in place, and are then replaced with four ski apparatuses. An anchoring plate connects springs from the underside of the skateboard deck to the ski apparatus base that maintains a traditional ski shape, with rails that protrude outward from the front and rear of the ski base, still maintaining a traditional ski shovel shape. The ski base, which has a flat or concave surface perpendicular to the length of the ski, contains a radius positioned longitudinally to the ski length (rocker) that then transitions to a small radius at the front and rear of the skis, thereby providing a traditional ski shovel in the front and rear of the ski base. Metal or plastic rails are mounted to the ski base on opposing sides of the base in a vertical fashion, extending below the surface of the base.

Abstract: A collapsible snowboard pole is presented. In exemplary embodiments of the present invention a snowboard pole can be provided with a manually expandable and compressible shaft, a basket at the tip, and a handle at the top. The basket can slide between a lower tip-ward (distal) position for storage and an upper top-ward (proximal) position for use. In exemplary embodiments of the present invention the pole can be expanded to full length and disengaged from a docking mechanism located at the back of a snowboard with one hand, while a user is in motion on the snowboard. Once disengaged, the user can easily deploy the basket to its full upward extension for use. Additionally, a user can dock a collapsed pole and secure it in a docking mechanism, or can insert the pole tip in a docking mechanism, then collapse the pole and then secure it in the docking mechanism, all with one hand while in motion on the snowboard.

Abstract: A sliding device for snow is provided with a supporting slide (1) and a turning slide (2) arranged in front of the supporting slide. The smallest portion of said turning slide (2) is wider than the widest portion of the supporting slide (1). The ground contact portion (2a) of said turning slide spreads out forward and is essentially a trapezoid-like plate. The largest width of this ground contact portion is about 1.01–1.1 times the smallest width of the ground contact portion.

Abstract: A snowskateboard includes a support deck having an upper side and a lower side opposite the upper side. First and second trucks are mounted to the lower side. The trucks include rotatable yokes having axles. A set of first runners is disposed over the first yoke axle. A set of second runners is disposed over the second yoke axle. A first biasing mount is mounted in each of the first runners and disposed over the first axle. The first biasing mounts each have first biasing members configured to bias in a torsional direction relative to the first truck axle. A second biasing mount is mounted in each of the second runners and is disposed over the second axle. The second biasing mounts each have second biasing members configured to bias in a torsional direction relative to the second axle.

Abstract: A ski-snowboard device has a support board for the user and a plurality of ski pairs mounted to the underside of the board. The ski-snowboard has a steering and suspension system, connecting the skis in each pair, to provide paired steering and independent suspension. Each steering and suspension system preferably comprises two pivoting generally-V-shaped arms connecting the board to the skis, wherein the V-shaped arms are spaced apart at their top end connections to the board, and each connect to different portions of rocker members that hold the skis. The V-shaped arms pivot relative to the board, and the rocker members pivot relative to the arms and also relative to the skis. Shock-absorbing/biasing systems cushion vibrations and tune the suspension and steering. Thus, the skis move right and left, move to their inside edges, and swing forward and rearward, to properly steer the ski-snowboard right and left and up and down terrain, for enhanced handling and control by the user.
