Abstract
A throttle control device for use with a spring-return throttle wherein a rotatable sleeve on a handlebar must be rotated to advance the throttle, the throttle control device including a clamping arrangement receivable over the rotatable sleeve to be just forward of a handgrip normally received over the sleeve, the clamping arrangement having a tab that engages conventional equipment to prevent rotation of the clamping means, and including a lever operated cam for clamping the sleeve to hold the throttle in a pre-set position, the clamping arrangement being held in position by the handgrip.
Claims8
A throttle control device, for a throttle apparatus including a handlebar and throttle operating means mounted on said handlebar, said throttle operating means including a sleeve rotatably mounted on said handlebar, said sleeve being adapted for receiving a handgrip thereover, and a housing fixed to said handlebar adjacent to said sleeve, said control device comprising clamping means for selectively holding said throttle operating means in a predetermined position, characterized in that said clamping means includes a disk defining an aperture for receiving said sleeve, said disk being positionable between said handgrip and said housing with said handgrip substantially contiguous to said disk, anchoring means for preventing rotation of said disk with respect to said housing including a tab fixed to said disk and engageable with said housing, said disk including a plurality of sections, means for urging said plurality of sections away from one another to enlarge said aperture and allow free rotation of said sleeve with respect to said disk, and constricting means for urging said plurality of sections towards one another to constrict said aperture and restrict rotation of said sleeve.
A throttle control device, for a throttle apparatus including a handlebar and throttle operating means mounted on said handlebar, said throttle operating means including a sleeve rotatably mounted on said handlebar, said sleeve being adapted for receiving a handgrip thereover, and a housing fixed to said handlebar adjacent to said sleeve, said control device comprising clamping means for selectively holding said throttle operating means in a predetermined position, characterized in that said clamping means includes a disk defining an aperture for receiving said sleeve, said disk being positionable between said handgrip and said housing with said handgrip substantially contiguous to said disk, anchoring means for preventing rotation of said disk with respect to said housing including a tab fixed to said disk and engageable with said housing, said disk including at least one open portion separating adjacent sections of the disk, the aperture being large enough to allow free rotation of said sleeve with respect to said disk with the sections separated a predetermined distance, the control device further comprising constricting means for urging the sections toward one another so as to constrict said aperture until the disk engages and restricts rotation of the sleeve.
