Patent

CA 2206171

In-line skate equipped with an energizing device consisting of a boot (5) whose sole (6) is attached to an upper plate (3) of a frame (1) on a lower part of which the skate wheels (4) are mounted, the said boot including a low-mounted shaft (10) equipped with a rigid rear counter (12) on which pivots a collar (13) which is also rigid and is designed to surround the wearer's ankle and pivot around the joint (19) to counteract elastic return devices placed between the said shaft and the said collar, characterized in that these devices (100) are called into action at least during a pivot to the rear of the said collar (13) from a mid-way equilibrium position of rest (00') that is approximately vertical, and following an angular path whose amplitude is limited by an end stop (101) fixed to one part of the shaft (10) or to a corresponding part of the collar (13), so as to benefit from an elastic return by the latter at least in the forward direction, the strength of the return being proportional to the angular travel of the shaft within the limit set by the position of the end stop (101).

Patin à roues en ligne disposant d'un dispositif d'énergisation comportant une chaussure (5) dont la semelle (6) est associée à une platine supérieure (3) d'un châssis (1) sur une partie inférieure duquel sont disposées les roues de patinage (4), ladite chaussure comportant une tige basse (10) munie d'un contrefort arrière rigide (12) sur lequel est articulé un collier (13) également rigide apte à entourer la cheville de l'utilisateur et à pouvoir pivoter autour de l'articulation (19) pour agir à l'encontre de moyens de rappel élastiques interposés entre ladite tige et ledit collier, caractérisé en ce que ces moyens (100) sont sollicités au moins lors d'un pivotement vers l'arrière dudit collier (13) à partir d'une position d'équilibre inactive médiate (00'), sensiblement verticale et selon une course angulaire limitée en amplitude par une butée de fin de course (101) disposée fixement sur une partie de la tige (10) ou sur une partie correspondante du collier (13), de façon à bénéficier d'un rappel élastique de celui-ci au moins vers l'avant, selon une énergie de valeur proportionnelle à la course angulaire de la tige dans une limite maximale déterminée par la position de la butée fin de course (101).
