The present invention relates to an apparatus for attachment to a slidable runner, adjustable between a folded configuration for transport or storage and an unfolded configuration for use, and tunable to match various terrain characteristics and user characteristics and preferences.

A ski-attachable upright conveyance can have a swept-back handle, an upright frame, strengthening members, ski clamp attachments, a braking system, and a plurality of standing plates. The ski clamp attachments allow simple attachment to a variety of skis (skates, wheels, etc.) to form the base of the conveyance so that it can slide across snow, ice, etc. The standing plates provide a non-slip surface upon which a user places his/her feet, allowing the person to stand upright while operating the conveyance. A braking system can allow a user to safely control their speed, stop, etc. The upright frame sweeps upwards before joining the swept-back handle. The frame locks the ski clamp attachments together and provides rigidity. Additional rigidity and support can be added via strengthening support members. A user can vary the pressure and forces exerted on the swept-back handle to assist in steering.

The transport device provides a front wall, rear wall, two side walls, and a bed for storage of transported contents. Handle apertures located within the side walls and rear wall are strategically placed to allow the user to manipulate the transport device. The handle apertures enable users to easily position and manipulate the transport device for transporting items and use as a scoop. Storage recesses are found on the rear wall and side walls on the transport device. The elevated storage recesses allow storage above items transported on the bed of the transport device.

Disclosed is a support and suspension assembly for a snow sports board. The assembly includes a base configured to be attached to a snow sports board and a frame above the base. The frame includes a first portion extending vertically upward or upward and forward to an upper end. The frame further includes a second portion extending generally rearward from the upper end of the first portion. A seat is on the second portion of the frame. A shock absorber is connected between the base and the frame. A linkage assembly is pivotably connected between the base and the first portion of the frame.

The snow surface skimmer is provided with: a skimmer body; a steering handle, which extends upward at a slant from the skimmer body; a seat installed on a region of the skimmer body that is behind the steering handle; and a skimming board. The skimming board is detachably attached to the bottom surface of the skimmer body by a skimmer attachment mechanism so that the attachment position in the front-back direction is adjustable. A skimming board suited to the skimming person's body type, build, etc. can be attached to the skimmer body at the appropriate position in the front-back direction.

A surface walker for human beings consisting of a chassis holding four articulated, movable limbs for walking. Each limb rests on foot, ski or float. Chassis is topped with cushioned seat whereon user lies prone on chest and belly with access to limbs, which are activated with arms and legs. Chassis height and limb length are adjustable. User regulates walking gait, limb stride and motion frequency of limbs. Walker advances on land and water and diverse landscapes. Design incorporates optional computer-controlled power assistance for walker motion and use of mechanical hand for enhanced traction and anchoring effects.

A snow raft comprises a plurality of adjustable speed control studs to control the speed of the raft wherein adjustments are made by way of threading and unthreading the studs located within threaded sockets.

Snowmobile having a suspension assembly comprising an upper A-arm, a lower A-arm, and a ski leg. The ski leg is pivotably connected to the upper A-arm via an upper A-arm connector and to the lower A-arm via a lower A-arm connector and is pivotable about a kingpin axis. A ski is connected to the ski leg via a ski connector. The upper A-arm connector, the lower A-arm connector and the ski connector are positioned one with respect to the others such that the kingpin axis is behind the ski connector at a level of the ski connector when the ski is viewed from the side.
