Abstract
Abstract A bicycle indicator system for showing the operational state of a brake and the gear shift condition of the bicycle, in which a brake position indicator plate is moveably connected to a brake handle lever and in parallel with and above a gear shift indicator plate such that movement of the brake handle lever to operate the brake will move said brake indicator plate to cover simultaneously all of the gear shift indicia on a gear shift indicator plate from view by an operator and such that release of the brake by movement of the brake handle lever will move said brake position indicator plate to uncover the gear shift indicator plate for view by the operator.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
292 words
An indicator system for a bicycle having a brake system, gear shift system, and a frame, comprising: 1. a cabinet mounted on said frame, and having a pair of slots and an opening perforated on the top thereof; 2. pivot means affixed to said frame and inside of said cabinet; 3. brake handle means pivotally mounted on said pivot means and extending upward therefrom through one of said slots; 4. friction means for holding said brake handle means in position until moved manually, 5. gear shift handle means pivotally mounted on said pivot means and extending upward therefrom through the other of said slots; 6. speed indicating means secured to said cabinet opposite to and below said opening, said speed-indicating means having a surface with speed indication indicia thereon indicative of the gear shift condition of said gear shift system; 7. means connected to said gear shift hand means for indicating on said speed indicator means the speed corresponding to the gear shift position; 8. brake-indicating means movably mounted on said cabinet below said opening and parallel to said speed-indicating means, said brake-indicating means being of sufficient area to close said opening and having a surface with indicia indicative of the operational state of said brake; 9. means connecting said brake handle means and said brakeindicating means whereby movement of said brake handle means to operate said brake moves said brake indicator means over said gear shift indicator means to simultaneously cover all of said gear shift information indicia from view through said opening; and 10. restoring means for returning said brake indicating plate from covering position over said gear shift-indicating means when said brake handle means releases said brake and thereby enabling view of said speed indication indicia through said opening.
Claim 2
Dependent Claim
292 words
An indicator system for a bicycle having a brake system, gear shift system, and a frame, comprising: 1. a cabinet mounted on said frame, and having a pair of slots and an opening perforated on the top thereof; 2. pivot means affixed to said frame and inside of said cabinet; 3. brake handle means pivotally mounted on said pivot means and extending upward therefrom through one of said slots; 4. friction means for holding said brake handle means in position until moved manually, 5. gear shift handle means pivotally mounted on said pivot means and extending upward therefrom through the other of said slots; 6. speed indicating means secured to said cabinet opposite to and below said opening, said speed-indicating means having a surface with speed indication indicia thereon indicative of the gear shift condition of said gear shift system; 7. means connected to said gear shift hand means for indicating on said speed indicator means the speed corresponding to the gear shift position; 8. brake-indicating means movably mounted on said cabinet below said opening and parallel to said speed-indicating means, said brake-indicating means being of sufficient area to close said opening and having a surface with indicia indicative of the operational state of said brake; 9. means connecting said brake handle means and said brakeindicating means whereby movement of said brake handle means to operate said brake moves said brake indicator means over said gear shift indicator means to simultaneously cover all of said gear shift information indicia from view through said opening; and 10. restoring means for returning said brake indicating plate from covering position over said gear shift-indicating means when said brake handle means releases said brake and thereby enabling view of said speed indication indicia through said opening.
Claim 3
Dependent Claim
11 words
pivot means affixed to said frame and inside of said cabinet;
Claim 4
Dependent Claim
11 words
pivot means affixed to said frame and inside of said cabinet;
Claim 5
Dependent Claim
146 words
The indicator system of claim 1, wherein said opening is parallel to said slots, said restoring means comprises spring means; said connecting means comprises a pair of links pivotally mounted on said cabinet, one of said links being connected to said spring means, said one link having an extended portion contactable by said brake handle means whereby movement of said brake handle means to operate said brake moves said extended portion of said one link against pressure of said spring means to move said brake-indicating means perpendicular to direction of movement of said brake handle means, and direction of said slots, to cover said speed-indicating means to prevent view through said opening and whereby movement of said brake handle means to release said brake causes said spring means to move said brake-indicating means from above said speed-indicating means thereby to enable view thereof through said opening.
Claim 6
Dependent Claim
170 words
The indicator system of claim 1, wherein said opening is perpendicular to said slots, said speed-indicating means having indicia placed thereon readable in a direction perpendicular to said slots, said brake-indicating means having a surface displaced from and adjacent to said opening, said restoring means comprises spring means, said connecting means comprises a connecting element extending from said brake-indicating means in the same direction of said slots, a pair of lines pivotally mounted on said connecting element, one of said links being connected to said spring means, a contacting rod connectable to said one link and extending therefrom such as to be contactable by said brake handle means whereby movement of said brake handle means to operate said brake causes said brake-indicating means to move against pressure of said spring means, parallel to said slots and over said speeding indicating means to prevent view from said opening and movement of said brake handle means to release said brake causes said spring means to remove said brake-indicating means from said opening.
