Disclosed is a textile sliding surface with a functional layer (1) and a base layer (2), which are connected to each other by filament yarns. The functional layer (1) is formed of pile loops, whereby the height of the pile loops in the functional layer (1) has a height (4), depending on the sport, in the range 4-1 4 mm and the functional layer (1) has 400-2400 pile loops per dm.sup.2. The yarns are bound into the base layer (2) in the lower part of the pile loops by W-bonds (10).

A method for producing a sliding board includes bonding one or more solid components with one or more enhanced structural sections to produce a core layer. A first enhanced structural section of the enhanced structural sections includes a corrugated medium. The core layer is extended between a first layer and a second layer. The first layer and/or the second layer are moved toward the core layer.

A ski having a core that includes a left lateral edge, a right lateral edge, and at least one central inner core positioned between the two lateral edges. The core also includes a plurality of left wings arranged between at least one central inner core and the left lateral edge, each left wing forming an angle between 5° and 85° or between 95° and 175° with the longitudinal axis X, and a plurality of right wings arranged between at least one central inner core and the right lateral edge, each right wing forming an angle between 5° and 85° or between 95° and 175° with the longitudinal axis X.

A method of changing a shape of a gliding surface of a gliding device may involve, in response to longitudinal deflection of the gliding device, causing at least one force transfer element to move longitudinally relative to the gliding device. Causing the at least one force transfer element to move longitudinally relative to the gliding device may involve causing the at least one force transfer element to deflect first and second laterally opposite side elements of the gliding device along a portion of the gliding device extending longitudinally along a binding region of the gliding device. Apparatuses and gliding devices are also disclosed.

Provided are a sliding instrument having a low frictional resistance to the snow surface, the ice surface, or the water surface and having excellent sliding performance and a method for manufacturing the sliding instrument. A sliding instrument to slide on snow, ice, or water includes a sliding surface (1) to come into contact with the snow surface, the ice surface, or the water surface, and the sliding surface (1) has a surface roughness Ra of 1.0 m or less. A method for manufacturing the sliding instrument includes polishing a sliding surface (1) using a polishing composition slurry containing abrasives to make the sliding surface (1) have a surface roughness Ra of 1.0 m or less.

There is provided a snowboard attachment to a standard snowboard for riding under powder snow conditions. The snowboard attachment comprises a nose part, an elongate passage and a body part. The nose part is operable to attach to the standard snowboard for providing lift and float while riding on powder snow. The elongate passage has walls extending between an opening in a top surface of the snowboard attachment and an opening in a bottom surface of the snowboard attachment, and is orientated transverse to the longitudinal axis of the snowboard attachment. The walls of the elongate passage are configured to surround the standard snowboard. The body part is attached in operation to the nose part, and has clamp through openings. The clamp through openings are arranged to receive bolts of a binding clamp of the standard snowboard, such that the clamp through openings lie in operation between the binding clamp and the standard snowboard.
