Abstract

The invention relates to an actuator device (100) for a bicycle gearshift, comprising: - an actuation kinematic mechanism including a first body (112) configured to be fixed to a bicycle frame, a second body configured to support a derailleur of the gearshift and a pair of articulating connecting rods (104) that connect the first body (112) and the second body; - a drive member (120) configured to control the deformation of the actuation kinematic mechanism, the drive member (120) comprising a motor (121) fixedly connected to one (112) of the first body (112) and the second body, and a motion transmission element (122) having a predetermined rotation axis and set in rotation by the motor (121); - a snap mechanism (150) arranged between said motion transmission element (122) and a connecting rod (104) of said pair of connecting rods and comprising a first member (160) rotating integrally with said motion transmission element (122) and provided with a coupling seat (162) and a second member (170) fixedly connected to said connecting rod (104) and comprising a coupling element (172) that, when the actuator device (100) is in a first operative engagement configuration, is housed at least partially in said coupling seat (162) and allows the transfer of the rotation from said first member (160) to said second member (170) and that, when the actuator device (100) is in a second operative release configuration, is not housed in said coupling seat (162) and allows the free rotation of said first member (160) with respect to said second member (170). The second member (170) comprises a first cavity (174) extending along a first direction coinciding with said predetermined rotation axis and a second cavity (176) extending along a second direction substantially perpendicular to the first direction. Said first cavity (174) houses at least partially said first member (160) and said second cavity (176) houses a pre-loaded elastic element (178) pushing against said coupling element (172) along said second direction towards said first member (160) so that, when the actuator device (100) is in said first operative configuration, said coupling element (172) is pushed into said coupling seat (162).
