A fastening assembly for a ski crampon includes a hinge pin having a mounting portion and a securing portion. The mounting portion has a smaller dimension in a first direction and a larger dimension in a second direction, the first and second directions orthogonal to the longitudinal direction of the hinge pin. The securing portion has substantially the same dimension in the first and second directions. A mounting fastening portion defines a gap and an opening. The gap and the opening each extends substantially transversely to a ski longitudinal direction and substantially parallel to the ski surface. The gap receives the mounting portion of the hinge pin, which is inserted through the opening. The dimension of the opening in the ski longitudinal direction is larger than the dimension of the mounting portion in the first direction and smaller than the dimension of the mounting portion in the second direction.

A frame of a snowshoe has an annular frame, a vamp, a plurality of teeth and an upper, wherein the annular frame is made from a metal pipe with a triangular cross-section, the front end of the annular frame is upturned, the middle portion of the annular frame is horizontal, and the rear portion of the annular frame is horizontal or upturned; the annular frame has a top surface for mounting a vamp and has a bottom surface with a sharp downward angle, and the lateral teeth for anti-skid effect are mounted on the bottom surface of the frame. The snowshoe is simple in structure, light and easy to carry, high in strength, and firm and stable to mount, and is lightweight, safe and skid proof when walking on the snow and is convenient for climbing, so that it is suitable for people who like snow sports.

A portable snowboard with detachable parts comprises a first planar section and a second planar section. The first planar section comprises a first member of an interconnecting joint. A second end of the first planar section comprises the first member of the interconnecting joint. The second planar section comprises a second member of the interconnecting joint. The second end of the second planar section comprises a second member of the interconnecting joint. The first member of the interconnecting joint is detachably fastened to the second member of the interconnecting joint to engage the first planar section with the second planar section to form the portable snowboard.

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 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 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.

In a preferred embodiment a wheeled platform apparatus and method for use in rolling on a surface are provided. The apparatus includes a platform having a top surface, a bottom surface, a front portion, a center portion, a rear portion, and a first wheel and a second wheel that interface with or are positioned below the bottom surface of the platform to facilitate rolling movement of the platform. The apparatus may further include an attachment device interfacing with the top surface and the footwear, as well as a footrest to support the forefoot of another foot, or footwear.

An electronically controlled detachable motorized track system for a snowboard having front and rear baseplates sized to fit in a backpack with right and left motorized tracks having a length extending beyond the front and rear baseplates from proximate the rear of a snowboard to proximate the front of a snowboard and beyond the front and rear baseplates, each adapted for wrapping around drive rollers and freely rotating rear rollers. A hand controller wirelessly controls the tracks.

A ski seat assembly is provided that includes a support structure, a seat coupled to the support structure, and an adjustable binding insert mechanism coupled to the support structure. The adjustable binding insert mechanism including a toe piece, a heel piece, and an adjustable connector connecting the toe piece to the heel piece, wherein the adjustable connector is adjustable to adjust a length of the adjustable binding insert mechanism to fit into a binding on a ski.

A stowable motorized skateboard comprising a first board section, a second board section, a power supply section, and support bars. The first board section includes a locking mechanism and first support anchors. The second board section includes a controller, a motor, second support anchors, and power supply anchors. The power supply section is between the first and second board sections, encasing a battery electrically coupled to the controller and the motor, and including a catch receiving the locking mechanism. The power supply section further receives the power supply anchors. The support bars extend from the first board section to the second board section and receive the first support anchors and the second support anchors.

An electronically controlled detachable motorized track system for a snowboard having front and rear baseplates sized to fit in a backpack with right and left motorized tracks having a length extending beyond the front and rear baseplates from proximate the rear of a snowboard to proximate the front of a snowboard and beyond the front and rear baseplates, each adapted for wrapping around drive rollers and freely rotating rear rollers. A hand controller wirelessly controls the tracks.

A portable snowboard with detachable parts includes a first planar section with a first member of an interconnecting joint, and a second planar section with a second member of the interconnecting joint. The first member of the interconnecting joint is detachably fastened to the second member of the interconnecting joint to engage the first planar section with the second planar section to form the portable snowboard. An anti-folding member, detachably attached between the first planar section and the second planar section, is coplanar in construction with the first planar section and the second planar section to prevent a relative folding between the first planar section and the second planar section. Multiple communication accessories are positioned on predefined sections of the first planar section and the second planar section for recording and transmitting information regarding a snowboarding session using the portable snowboard to a base station and/or a user device.
