Title (EN) TOOTH CLUTCH TRANSMISSION FOR WHEELCHAIRS
(FR) TRANSMISSION D’EMBRAYAGE À DENT POUR CHAISES ROULANTES
Abstract:
(EN) A conveyance to carry humans, such as a wheelchair, is described having levers on each side of the wheelchair that are manually moved forward and backward to propel the conveyance. The levers are connected to a tooth clutch mechanism that allow the user to shift into forward, reverse or neutral, brake, and change mechanical advantage (gear ratio), all this without removing the user's hands from the drive levers.
(FR) La présente invention concerne un moyen de transport pour transporter des personnes, tel qu’une chaise roulante, présentant des leviers sur chaque côté de la chaise roulante qui sont manuellement déplacés vers l’avant et vers l’arrière pour propulser le moyen de transport. Les leviers sont reliés à un mécanisme d’embrayage à dent qui permet à l’utilisateur de passer en marche avant, en marche arrière ou en position neutre, de freiner, et de changer l'avantage mécanique (le rapport d’engrenage), tout ceci sans que l’utilisateur retire ses mains des leviers d’entraînement.
