Patent

CA 2178905

A treadmill device includes a frame (12) and two side by side treadmills (14) each having a continuous tread (34) and first and second ends. The first ends of the two treadmills are pivotally supported on a base portion of the frame by a roller shaft (32) which extends through the treadmill rollers. The second ends of the treadmills are independently supported by spring return hydraulic cylinders (38) which are connected between the treadmills and spaced support members of the frame. The continuous treads are driven by a motor (18) which is coupled to the roller shaft. The treadmills alternately pivot up and down as a user walks thereon.

Une trépigneuse comprend un cadre (12) et deux tapis de marche (14) contigus dont chacun comporte une surface de marche continue (34) et deux extrémités. La première extrémité de chaque tapis de marche est supportée de façon pivotante sur une partie de base du cadre à l'aide d'un arbre à rouleaux (32) qui traverse les rouleaux du tapis de marche. La deuxième extrémité de chaque tapis de marche est supportée de façon indépendante par les vérins hydrauliques rappelés par ressort qui sont montés entre les tapis de marche et des éléments de support espacés du cadre. Les tapis continus sont entraînés par un moteur (18), qui est couplé à l'arbre à rouleaux. Les tapis de marche pivotent alternativement vers le haut et vers le bas pendant qu'un utilisateur marche sur eux.
