The invention relates to a sporting device (1), in particular a touring ski assembly. The sporting device (1) comprises a sliding body (2) on which a bottom side (3) is designed as a sliding surface (4). Furthermore, the sporting device (1) comprises a binding apparatus (6) disposed on the top face (5) of the sliding body (2) for fastening to a sporting shoe (7) of a user (8) in such a way that the fastening can be released as and when necessary, a circulating belt (13) having a first segment (14) for establishing a relative motion between the sliding body (2) and the ground (12) and a second, returning segment (15), as well as a drive apparatus (17) and at least one first deflecting apparatus (18) for the belt (13). The first segment (14) is disposed next to the bottom side (3) of the sliding body (2) and the second, returning segment (15) is disposed next to the top face (5) of the sliding body (2). At least the majority of the length (9) of the sliding body (2) is surrounded by the circulating, intrinsically closed belt (13). By means of this design, a user can be supported with regard to his advancing movement, in particular the overcoming of ascents and mountain routes can thereby be made easier, such that the body force or performance capacity to be applied by the user can be lower.

A method, system and apparatus for carrying a user including a board for supporting the user, a ground-contacting member coupled with the board, a motorized drive assembly coupled with the ground-contacting member and one or more sensors coupled with the drive assembly. In operation, the drive assembly adjusts the velocity of the ground-contacting member based on one or more distances of the board from a surface below the board as detected by the sensors. As a result, the system is able to maintain a desired velocity when ascending, descending or traversing uneven ground without the need for excessive and sometimes impossible tilting of the board.

An apparatus comprising a platform; a plurality of trucks coupled to the platform; and a roller assembly coupled to the platform, wherein the roller assembly is configured for an omnidirectional rotation, wherein the roller assembly is configured for an elastic biasing, wherein the roller assembly is driven by a motor.

The jumping platform has a lateral mounting portion and a lateral lapping portion respectively formed on two lateral surfaces of the jumping platform. The extendable jumping platform assembly has multiple jumping platforms, multiple extending boards, and a jumping board. The jumping platform assembly has a lateral mounting portion and a lateral lapping portion so that the jumping platforms and the extending boards can be juxtaposed for extending lateral leaping range safely and extending sliding length according to the usage. One end of the extending board is mounted on the jumping platform, the other end of the extending board is mounted on the jumping board, and each one of the extending board and the jumping board has a leg assembly for supporting.

A motorized personal transportation article is described which transports a person by wearing a pair of power-assisted motorized shoes, wherein the shoes provide an increase in a user's walking speed in a forward walking action through supplementary motion of moving or propelling means based on an intended walking speed of the user, such that when a user's intended walking speed changes or when a user intends to substantially decelerate or immobilize, the speed of the supplementary motion can be adjusted before the step is completed. The sole of each of the shoes houses at least one plate coupled to moving or propelling means such as conveyor assemblies, and the moving or propelling means are designed to neutralize forces acting to disrupt the operation of the moving or propelling means during a forward walking action or the balance and comfort of the user.
