Patent ID: 7770490

Claim:
A motor throttle assembly, for attachment on a handle bar, comprising: a fixed assembly and a rotating assembly; said fixed assembly comprising a rigid tubular inner sleeve and a cable pull; said inner sleeve having means for attachment on said handle bar and having a pair of aligned diametrically opposed longitudinal cutouts; said cable pull being slidably disposed within said inner sleeve and having means for attaching a throttle cable; said cable pull having a pair of opposed outwardly extending guide posts designed to rest within and protrude outward through said longitudinal cutouts; said rotating assembly comprising a rigid tubular outer sleeve and bearing means; said outer sleeve having a pair of longitudinally extending helical cutouts in counterpoise relation; said rotating assembly being designed to receive said fixed assembly therein, with said bearing means interposed in rotatable supporting relation, and said pair of longitudinal cutouts underlying said pair of helical cutouts for receiving said pair of guide posts through said longitudinal cutouts and into said helical cutouts; whereby rotation of said rotating assembly draws said guide posts along said helical cutouts, with balanced force, and causes said cable pull to traverse said inner sleeve and accelerate a motor; and a first pair of guide post bearing sets mounted on said guide posts, for reducing friction between said guide posts and said longitudinal cutouts and a second pair of guide post bearing sets mounted on said guide posts for reducing friction between said posts and said helical cutouts.
