<p>Device for management of two derailleurs for cycles. The device comprises actuating means connected to two derailleur gears by transmission means (C1, C2). It is characterized in that it comprises a cam (26, 81, 82) which is driven in rotation with respect to a second element (42, 64) by the action of actuating means and which acts on an element of a fixed part (12, 60) of the device. The reaction of said fixed part induces a movement nof a part (20, 71, 72) of the device carrying at least one of said elements and on which the transmission means are integral. The movement occurs simultaneously with the rotation of the first element (26, 80), so that traction is exerted at the same time in the same direction on said transmission means (C1, C2), one of which is caused to move. Application to the cycle industry.</p> |
