Patent

CA 2045556

There is disclosed a pedal powered structure in which a frame carrying a seat (12) and an axle (14) with a pivotally mounted pedal (15) on each side thereof is modified to include a pedal axle (17) extension beyond the pedal (15) at its inner and outer ends to provide inner and outer extensions, said pedal axle (17) rotating on a bearing (70) mounted within a crank assembly (16). Ligatures, (20, 21) one for each pedal axle extensions (18, 19) are connected at one end to one of the pedal axle extensions (18, 19) at the other end to an element (25) mounted behind and below the seat (12). The parallel ligatures (20, 21) spaced apart by approximately the width of the pedal, and strap means (22) are secured between each pair of parallel ligatures (20, 21) intermediate its length to rest upon the thigh of the rider above the knee when the rider is using the pedal powered structure. Ligatures (20, 21) are connected to the ends of strap (22) by means of two pulleys (23, 24), one on each end of the said strap (22).

Véhicule à pédales dont le cadre, supportant une selle (12) et un axe (14) sur lequel est montée de chaque côté une pédale (15) pivotante, a été modifié pour comprendre une rallonge d'axe de pédale (17) se prolongeant au-delà de la pédale (15), sur ses extrémités interne et externe afin d'obtenir des rallonges interne et externe. L'axe de pédale (17) tourne au moyen d'un roulement (70) monté à l'intérieur d'une manivelle (16). Des raccords (20, 21), un par rallonge d'axe de pédale (18, 19), sont reliés, à une extrémité, à une des rallonges d'axe de pédale (18, 19) et, à l'autre extrémité, à un dispositif (25) monté derrière et au-dessous de la selle (12). Les raccords parallèles (20, 21) sont espacés d'environ la largeur de la pédale, et des courroies (22) placées à mi-distance des raccords relient chaque paire de raccords parallèles (20, 21), de manière à reposer sur la cuisse du cycliste, au-dessus du genou, lorsque le cycliste utilise le véhicule à pédales. Les raccords (20, 21) sont fixées aux extrémités des courroies (22) au moyen de deux poulies (23, 24), une à chaque extrémité des courroies (22).
