Abstract
A bicycle electric/electronic derailleur has a plurality of mutually movable components: a support body configured to be attached to a bicycle frame, a chain guide, and a pair of connecting arms, for connection between the support body and the chain guide at respective geometric articulation axes. A geared motor controls the motion of the plurality of mutually movable components. At least one first component has a case with a chamber containing the geared motor and/or one or more electric/electronic devices. The chamber crosses at least one articulation axis. The case comprises a blind hole that is coaxial with the one axis and open outwards of the case. A second component has a pivot pivotable in the blind hole.
Claims12
A bicycle electric/electronic derailleur comprising:
- a plurality of mutually movable components, comprising a support body configured to be attached to a bicycle frame, a chain guide, and a pair of connecting arms comprising a proximal connecting arm and a distal connecting arm, for connection between the support body and the chain guide at respective geometric articulation axes, comprising a support body-proximal connecting arm articulation axis, a support body-distal connecting arm articulation axis, a chain guide-proximal connecting arm articulation axis, and a chain guide-distal connecting arm articulation axis,
- a geared motor for controlling mutual motion of the plurality of mutually movable components,
- wherein at least one first component of the mutually movable components comprises a case,
- wherein a chamber containing said geared motor and/or one or more electric/electronic devices is formed in said case, the chamber crossing at least one first axis of the two among said articulation axes to which the first component is articulated,
- wherein said case comprises a first blind hole coaxial with said crossed first axis and open outwards of said case, and a second component of the mutually movable components articulated to the first component at said crossed first axis comprises a pivot pivotable in the first blind hole.
