An apparatus for training a student to ski is a ski pole that, used in a pair and held laterally, converts to guiding harness. The apparatus is configured as a pair arranged around the student and held by both student and instructor. The apparatus converts to typical-use ski poles when training is complete. The apparatus is configured like a typical-use ski pole, but articulated with a ratchet joint that enables arrangement around the student.

A non-motorized transport device including first and second skis; first front and rear fastening feet fastened on the first ski and second front and rear fastening feet fastened on the second ski; a longitudinal beam; an edging handle fastened to the longitudinal beam; and a connecting system connecting the longitudinal beam to the first and second front and rear fastening feet, the connecting system including first and second front connecting rods each including a middle portion pivotally mounted on the longitudinal beam about a respective front articulation axis and first and second end portions which are respectively connected to the first and second front fastening feet by respective front ball joint connections, and a rear connecting rod including a middle portion pivotally mounted on the longitudinal beam about a rear articulation axis and first and second end portions respectively connected to the first and second rear fastening feet by respective rear ball joint connections.

Method of using a snowboard training apparatus for transferring the feel of toe side and heel side of a snowboard from an instructor to a snowboard learner is disclosed. The training apparatus includes a training rod having a first and second end. The first end and second end of the training rod can be adapted to be supported by a snowboarder's leg, snowboarder's boot, snowboard's bindings or a snowboard itself. The training apparatus can also include a second training rod.

A restricted, preferably spring elastic and dampened movability of transversal struts (5a, b) in the longitudinal direction (10) with respect to a skid (2a) supporting the transversal struts prevents a transmission and build-up of vibrations through the connection units (3) at the piece of winter sports equipment (1).

A device allowing the control of a pair of skis or a surfboard, in particular for snow, by the combined simple rotation and simple tilting of a single drive member such as a handlebar, simultaneously by lateral inclination and by longitudinal warping. It therefore combines the necessary mechanical functionalities of a pair of conventional fasteners with the ease of use of a bicycle and does not require skis or specific surfboard. It allows you to move freely over the snow by driving with both feet which are retained but not locked, or to use one foot to push on the flat and stabilize. The lever arm offered by the drive body is much greater than that of a pair of conventional fasteners, greatly improving the ease of use and the maximum capabilities of the machine. Finally, it instantly folds back for easy handling and storage.

The invention relates to a mating device (2) for mating two skates, characterized in that it comprises a first fastening module (6) and a second fastening module (6′), each designed to be fastened to a skate and comprising a body (7) between the two fastening modules (6, 6′), the said body (7) allowing at least a translational freedom between the two fastening elements (6, 6′), the distance between the two fastening modules (6, 6′) being free between a predetermined minimum distance and a predetermined maximum distance.

A ski winter sports device for sliding down a hill. The ski winter sports device includes a first ski, a second ski and a third ski, a standing device on which a user can stand, a holding device, and a frame. The first and second skis are arrangeable on the standing device next to each other in a direction of travel so that the first ski is available for a first foot of the user and the second ski is available for a second foot of the user. The holding device can be held by at least one hand of the user. The frame connects the standing device to the holding device. The frame is connected to the standing device in a relatively movable manner. The frame and the standing device are foldable relative to each other so that a spatial volume of the ski winter sports device is reducible.
