Abstract
Abstract A device for displaying the gear parameters of a bicycle comprises a sensor for detecting the position of the member (or members) for controlling the gear-change, and display means connected to the sensor means and able to supply a signal indicative of the ratio engaged. In a preferred embodiment, the number of teeth of the two gear-wheels (front and rear) on which the chain is engaged are displayed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
127 words
A device for displaying gear parameters of a bicycle, including a driving chain engageable selectively with a series of sprockets connected to the hub of the wheel in order to obtain different gear ratios and a member for controlling the lateral movement of the chain from one sprocket to another, said device further comprisng: (a) sensor means for detecting the position of the control member; (b) display means connected to the sensor means and able to supply a signal indicative of the ratio engaged; (c) said display means displaying the number of teeth of a particular sprocket of said series of sprockets with which the chain is engaged; and (d) wherein said display means supplies the value of the distance covered by each push on a pedal.
Claim 2
Independent Claim
127 words
A device for displaying gear parameters of a bicycle, including a driving chain engageable selectively with a series of sprockets connected to the hub of the wheel in order to obtain different gear ratios and a member for controlling the lateral movement of the chain from one sprocket to another, said device further comprisng: (a) sensor means for detecting the position of the control member; (b) display means connected to the sensor means and able to supply a signal indicative of the ratio engaged; (c) said display means displaying the number of teeth of a particular sprocket of said series of sprockets with which the chain is engaged; and (d) wherein said display means supplies the value of the distance covered by each push on a pedal.
Claim 3
Dependent Claim
188 words
Device for displaying the gear parameters of a bicycle including a driving chain engageable selectively with a series of sprockets connected to the hub of the rear wheel in order to obtain different gear ratios, and a member for controlling the lateral movement of the chain from one sprocket to another, said device further comprising: (a) sensor means for detecting the position of the control member; (b) display means connected to the sensor means and able to supply a signal indicative of the ratio engaged; and (c) said control member including a lever mounted rotatably on a hub fixed to the frame of the bicycle, wherein the sensor means comprise a plurality of movable contacts fixed to the lever and a fixed contact fixed to the hub in such manner that upon the rotation of the lever, the movable contacts are selectively snap-engaged with the fixed contact so as to ensure both an electrical connection between the contacts and the precise positioning of the lever, the movable contacts having a mutual spacing chosen in dependence on the number of sprockets assiciated with the hub of the rear wheel.
Claim 4
Dependent Claim
