Patent

CA 2403363

The invention relates to a rolling sports equipment, especially an inline skateboard or an inline roller skate, with two roller axles disposed one behind the other in a single line and mounted on a board or a portable frame. The rear-most of the two roller axles (rear axle) can be pivoted about an axis (steering axis) extending forward and downward at an angle, which forms a squint angle. The treads of the rollers are bent in a direction transverse to the direction of rotation and have a high coefficient of friction comparable to that of rubber.

L'invention concerne un article de sport à roulettes, notamment une planche à roulettes en ligne ou un patin à roulettes en ligne, qui présente deux axes de roulettes placés l'un derrière l'autre sur lesquels sont montées des roulettes roulant en ligne l'une derrière l'autre et qui sont fixés sur une planche ou sur un châssis-support. Selon l'invention, l'axe postérieur des deux axes de roulettes (axe arrière) peut pivoter autour d'un axe descendant obliquement vers l'avant (axe de direction) qui forme un angle de chasse. Les surfaces de roulement des roulettes sont courbées perpendiculairement au sens de rotation et présentent un coefficient de frottement élevé, similaire à celui du caoutchouc.
