Abstract
The invention concerns a member for fixing (1) a bicycle wheel friction drive device comprising a first part (2) linked to said driving device (3), so as to be pivotable about a first pivot pin (4), and a second part (5) attached to the first part (2), so as to enable mutual pivoting between them about a second pivot pin (6), said second part (5) including a fastener (7) located at a predetermined distance from said second pivot pin (6), said fixing member (1) further comprising adjusting means designed to fix in an adjustable angular position the first part (2) relative to the second part (5).
Claims9
A member (1) for fixing a device for driving a bicycle wheel by friction, comprising
- a fastener (7) connected to an element of the bicycle frame,
- the friction drive device (3) being arranged so as to be able to pivot freely about a first pivot pin (4), characterised in that the fixing member also comprises
- a first part (2), to which the drive device is connected so as to be able to pivot freely about the said first pivot pin (4),
- a second part (5), which is connected to the first part (2) so as to allow mutual pivoting between the first part (2) and the second part (5) about a second pivot pin (6) before clamping and keeping them integral with each other, and the second part (5) comprises the said fastener (7), at a distance from the said second pivot pin,
- adjustment means (17-19:26-27) capable of detachably fixing the first part (2) with respect to the second part (5) in an angular position adjustable by the said mutual pivoting so that after the adjustment the first part (2) is fixed with respect to the second part (5), and
- means (22-25) of modifying the separation between the first pivot pin (4) and the second pivot pin (6), and therefore adjusting the length between the fastener and the drive device so as to place the drive wheel on the bicycle tyre according to the bicycle configuration.
