Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
160 words
A hand control device for a speed change gear mechanism for a bicycle with the device arranged to be mounted on the handle bar of the bicycle adjacent a hand grip on the handle bar, wherein the improvement comprises a drive means, holder means arranged to mount said drive means on the handle bar so that said drive means is rotatable about the axis of the handle bar, said drive member including a knob arranged to extend outwardly from the handle bar so that it is accessible for rotating said drive member from the hand grip on the handle bar, a driven member mechanically interengaged with said drive member for rotation about an axis angularly intersecting the axis of rotation of said drive member, and a wire secured to said driven member and movable therewith when said driven member is rotated by said drive member and said wire extending from said driven member for operating the speed change gear mechanism.
Claim 2
Dependent Claim
160 words
A hand control device for a speed change gear mechanism for a bicycle with the device arranged to be mounted on the handle bar of the bicycle adjacent a hand grip on the handle bar, wherein the improvement comprises a drive means, holder means arranged to mount said drive means on the handle bar so that said drive means is rotatable about the axis of the handle bar, said drive member including a knob arranged to extend outwardly from the handle bar so that it is accessible for rotating said drive member from the hand grip on the handle bar, a driven member mechanically interengaged with said drive member for rotation about an axis angularly intersecting the axis of rotation of said drive member, and a wire secured to said driven member and movable therewith when said driven member is rotated by said drive member and said wire extending from said driven member for operating the speed change gear mechanism.
Claim 3
Dependent Claim
203 words
A hand control device for a speed change gear mechanism for a bicycle with the device arranged to be mounted on the handle bar of the bicycle adjacent a hand grip on the handle bar, wherein the improvement comprises a drive member, cogwheel teeth formed in the circumferential periphery of said drive member, said drive member including a knob arranged to extend outwardly from the handle bar so that it is accessible for rotating said drive member from the hand grip on the handle bar, holder means arranged to mount said drive member on the handle bar so that said drive member is rotatable about the axis of the handle bar, a driven member arranged to be mounted on the handle bar for rotation about an axis intersecting the axis of said drive member and said driven member having cogwheel teeth formed in the circumferential periphery thereof, said cogwheel teeth on said driven member being in interengagement with said cogwheel teeth on said drive member for transferring rotatable motion from said drive member to said driven member, and a wire secured to said driven member and being movable therewith, said wire extending from said driven member for operating the speed change gear mechanism.
Claim 4
Dependent Claim
203 words
A hand control device for a speed change gear mechanism for a bicycle with the device arranged to be mounted on the handle bar of the bicycle adjacent a hand grip on the handle bar, wherein the improvement comprises a drive member, cogwheel teeth formed in the circumferential periphery of said drive member, said drive member including a knob arranged to extend outwardly from the handle bar so that it is accessible for rotating said drive member from the hand grip on the handle bar, holder means arranged to mount said drive member on the handle bar so that said drive member is rotatable about the axis of the handle bar, a driven member arranged to be mounted on the handle bar for rotation about an axis intersecting the axis of said drive member and said driven member having cogwheel teeth formed in the circumferential periphery thereof, said cogwheel teeth on said driven member being in interengagement with said cogwheel teeth on said drive member for transferring rotatable motion from said drive member to said driven member, and a wire secured to said driven member and being movable therewith, said wire extending from said driven member for operating the speed change gear mechanism.
Claim 5
Dependent Claim
69 words
A hand control device, as set forth in claim 2, characterized in that said holder means comprises a first handle bar holder and a second handle bar holder, said first and second handle bar holders being shaped to fit about and closely engage the handle bar, and connecting means for securing said first and second handle bar holders together and for securing said holding means on the handle bar.
Claim 6
Dependent Claim
210 words
A hand control device for a speed change gear mechanism for a bicycle with the device arranged to be mounted on the handle bar of the bicycle adjacent a hand grip on the handle bar, wherein the improvemenT comprises a drive member, holder means arranged to mount said drive member on the handle bar so that said drive member is rotatable about the axis of the handle bar, said drive member including a knob arranged to extend outwardly from the handle bar so that it is accessible for rotating said drive member from the hand grip on the handle bar, a casing secured to said holder means, a shaft located within said casing, a drive member rotatably mounted on said shaft, a speed indicating disk plate located on said driven member, said casing comprising a cover plate covering said speed indicating disk plate, and said cover plate having an opening for viewing said disk plate, and said cover plate having indicator marks thereon along the opening therethrough for indicating the speed changes effected by the speed change gear mechanism, and a wire secured to said driven member and being displaceable when said driven member is rotated, said wire extending from said driven member for operating the speed change gear mechanism.
